Self-propelled robot for the handling of explosive charges
A self-propelled robot is used to handle explosive charges and is of the type that is remote controlled by a control console. The robot can be used to handle explosive devices and charges as well as perform special, dangerous operations. The self-propelled robot includes a chassis, and two laterally spaced-apart endless tracks having adjustable lateral spacing, and an adjustable-length scraper disposed at the front thereof. The robot also includes an articulated arm having a first segment which takes the form of a fork that is actuated by a pair of cylinders and which terminates in a clamp. The articulated arm is foldable between an extended position and a folded condition.
1. A remotely-controlled self-propelled robot for the handling of explosive charges, comprising:
a chassis;
a pair of laterally spaced-apart endless tracks for moving the chassis in a running direction, said endless tracks being adjustably disposed in a laterally spaced-apart relationship such that an amount of space laterally between said endless tracks is adjustable;
an adjustable-length scraper mounted at a front of said chassis so as to be adjustable in length in a lateral direction of said chassis;
an articulated arm provided at a front of said chassis, said articulated arm having a plurality of mutually articulable segments including a first segment pivotably connected to said chassis;
a clamp provided at an end of said articulated arm; and
at least one hydraulic cylinder connected between said chassis and said first segment for actuating movement of said articulated arm;
wherein said first segment of said articulated arm includes a first portion connected to said chassis, and a second portion inclined at an angle relative to said first portion;
wherein said first segment is fork-shaped such that at least said first portion thereof has two spaced-apart prong portions;
wherein said at least one hydraulic cylinder is connected to said first segment near an intersection of said first and second portions of said first segment; and
wherein said articulable segments of said articulated arm are mutually connected so that said articulated arm is foldable between an extended condition in which said articulable segments extend forwardly of said chassis, and a folded condition in which said first portion of said first segment extends upwardly and rearwardly, said second portion of said first segment extends substantially horizontally rearwardly, and a portion of said articulated arm extends between said spaced-apart prong portions of said first portion of said first segment of said articulated arm such that said clamp and a portion of said articulated arm are extended rearwardly beyond said spaced-apart prong portions of said first portion of said first segment of said articulated arm.
2. The remotely-controlled self-propelled robot according to claim 1 , wherein
said articulated arm and said clamp are configured and arranged such that, when said articulated arm is in said folded condition, said clamp is superposed vertically above said chassis and said endless tracks.
3. The remotely-controlled self-propelled robot according to claim 2 , further comprising
telescopic cross-members mounting said laterally spaced-apart endless tracks to said chassis; and
at least one hydraulic cylinder operably connected to said laterally spaced-apart endless tracks for adjusting the lateral space therebetween.
4. The remotely-controlled self-propelled robot according to claim 3 , wherein
said adjustable-length scraper includes a laterally-extending center scraper part and rotary arms at laterally-opposing ends of said laterally-extending center scraper part for adjusting the length of the adjustable-length scraper in the lateral direction of said chassis.
5. The remotely-controlled self-propelled robot according to claim 4 , wherein
said adjustable-length scraper is configured to be folded between an extended condition in which said rotary arms extend laterally away from said laterally-extending center scraper part, and a folded condition in which said rotary arms are folded in superposed relation with said laterally-extending center scraper part.
6. The remotely-controlled self-propelled robot according to claim 1 , further comprising
telescopic cross-members mounting said laterally spaced-apart endless tracks to said chassis; and
at least one hydraulic cylinder operably connected to said laterally spaced-apart endless tracks for adjusting the lateral space therebetween.
7. The remotely-controlled self-propelled robot according to claim 6 , wherein
said adjustable-length scraper includes a laterally-extending center scraper part and rotary arms at laterally-opposing ends of said laterally-extending center scraper part for adjusting the length of the adjustable-length scraper in the lateral direction of said chassis.
8. The remotely-controlled self-propelled robot according to claim 7 , wherein
said adjustable-length scraper is configured to be folded between an extended condition in which said rotary arms extend laterally away from said laterally-extending center scraper part, and a folded condition in which said rotary arms are folded in superposed relation with said laterally-extending center scraper part.
9. The remotely-controlled self-propelled robot according to claim 1 , wherein
said adjustable-length scraper includes a laterally-extending center scraper part and rotary arms at laterally-opposing ends of said laterally-extending center scraper part for adjusting the length of the adjustable-length scraper in the lateral direction of said chassis.
10. The remotely-controlled self-propelled robot according to claim 9 , wherein
said adjustable-length scraper is configured to be folded between an extended condition in which said rotary arms extend laterally away from said laterally-extending center scraper part, and a folded condition in which said rotary arms are folded in superposed relation with said laterally-extending center scraper part.
11. The remotely-controlled self-propelled robot according to claim 1 , wherein
said at least one hydraulic cylinder comprises plural hydraulic cylinders.
