[0032] In the existing technology, there are various types of materials used in underground coal mines, and a single type of lifting device cannot realize the loading, unloading and installation of different types of materials; a large amount of auxiliary materials are required for loading, unloading and installation during the underground coal mine tunnels, development and support processes, which currently mainly rely on manual handling, which is labor-intensive, dangerous and inefficient. Mechanization is needed to replace manual labor, reduce labor intensity, improve work efficiency and enhance safety; the underground coal mine tunnels are narrow, and different lifting devices are required for the loading, unloading and installation of different materials, and equipment replacement takes too long.

[0033] See also Figure 1-6 The present invention provides a technical solution: a mechanical claw type vehicle-mounted lifting device for an explosion-proof diesel engine crawler transport vehicle for mining, comprising an explosion-proof diesel engine crawler transport vehicle body 1, wherein a walking crawler 2 for movement is installed at the bottom of the explosion-proof diesel engine crawler transport vehicle body 1; a mechanical claw type lifting assembly 3, wherein the mechanical claw type lifting assembly 3 is installed at the top of the explosion-proof diesel engine crawler transport vehicle body 1; the mechanical claw type lifting assembly 3 comprises a clamping claw assembly and a lifting assembly, wherein the clamping claw assembly is arranged on one side of the lifting assembly; the mechanical claw type lifting assembly 3 is powered and stabilized by the explosion-proof diesel engine crawler transport vehicle body 1, and is fully hydraulically controlled, with stable output, high safety performance, smooth operation, strong lifting and snatching capabilities, and fast switching between the lifting function and the snatching function, and can be operated separately, and can be quickly adjusted according to different complex working conditions and demand conditions;

[0034] The lifting component and the gripper component are designed to be foldable in one piece, with a high degree of integration. Both lifting and pipe grabbing can be achieved without disassembly or assembly, without affecting the overall performance and trafficability of the vehicle. It can directly adapt to the lifting operations of different materials, and can be used for both material lifting operations and auxiliary installation operations of pipelines.

[0035] When the lifting assembly is in use, the lifting assembly includes a first slewing reducer 5, a boom column 6 and a boom 9. The first slewing reducer 5 is installed on the top of the explosion-proof diesel engine crawler transport vehicle body 1, and the boom column 6 is installed on the top of the first slewing reducer 5. One end of the boom 9 is hinged to one end of the boom column 6. A mechanical claw arm 13 is installed inside the boom 9, and a hook 16 is installed at one end of the mechanical claw arm 13. A telescopic assembly is provided on one side of the boom 9. The telescopic assembly includes a telescopic oil cylinder 12, one end of the telescopic oil cylinder 12 is fixedly connected to one side of the boom 9, and the piston rod of the telescopic oil cylinder 12 is installed on the telescopic arm 14 through a bracket.

[0036] When the gripper assembly is in use, the gripper assembly includes a second rotary reducer 15, a mechanical claw arm 13 and two mechanical claws 8. The second rotary reducer 15 is installed on the other side of the telescopic arm 14. The mechanical claw arm 13 is installed on the second rotary reducer 15. A rotary oil cylinder 11 is installed at one end of the mechanical claw arm 13. A mounting seat is installed at one end of the rotary oil cylinder 11. The two mechanical claws 8 are respectively hinged on both sides of one end of the mounting seat. An opening and closing assembly is installed on the mounting seat. The opening and closing assembly includes two mechanical claw cylinders 10. One end of the two mechanical claw cylinders 10 is respectively hinged. The two mechanical claws 8 are hinged on both sides of the mounting base, and the piston rods of the two mechanical claw cylinders 10 are respectively hinged on the two mechanical claws 8; the mechanical claw arm 13 is driven to rotate by the second rotary reducer 15, which can drive the mechanical claw arm 13 to rotate 360 ​​degrees. When the mechanical claw 8 needs to be rotated, the rotary cylinder 11 is driven to rotate so that the mechanical claw 8 can be rotated 360 degrees, thereby facilitating the use of the mechanical claw 8. When it is necessary to clamp the material, the piston rod of the mechanical claw cylinder 10 is driven to extend, thereby pushing one end of the two mechanical claws 8 to close, so as to clamp the material.

[0037] A hydraulic control valve group 4 is installed on the rear side of the explosion-proof diesel engine crawler transporter body 1. The hydraulic control valve group 4 is used to drive the extension and reset of the pistons of the lifting cylinder 7, the mechanical claw cylinder 10, the rotary cylinder 11 and the telescopic cylinder 12. The deployment angle of the boom 9 is fifty-one degrees.

[0038] The working principle or structural principle is that when in use, the rotation of the first rotary reducer 5 can drive the mechanical claw lifting assembly 3 to rotate 360 ​​degrees, and the mechanical claw lifting assembly 3 moves to a suitable position, and the valve stem of the hydraulic control valve group 4 drives the piston rod of the lifting cylinder 7 to extend, so that the piston rod of the lifting cylinder 7 pushes the boom 9 to unfold, and then the valve stem of the hydraulic control valve group 4 drives the piston rod of the telescopic cylinder 12 to extend, and the piston rod of the telescopic cylinder 12 drives one end of the telescopic arm 14 to move through the bracket, so that the telescopic arm 14 moves out of the inside of the boom 9, which is convenient for lifting materials.

[0039] When the mechanical claw 8 is used, the mechanical claw arm 13 is driven to rotate by the second rotary reducer 15, which can drive the mechanical claw arm 13 to rotate 360 ​​degrees. When the mechanical claw 8 needs to be rotated, the rotary cylinder 11 is driven to rotate by the hydraulic control valve group 4, so that the mechanical claw 8 can rotate 360 ​​degrees, thereby facilitating the use of the mechanical claw 8. When it is necessary to clamp materials, the piston rod of the mechanical claw cylinder 10 is driven to extend by the hydraulic control valve group 4, thereby pushing one end of the two mechanical claws 8 to close, so as to facilitate clamping of materials. The above components are coordinated to complete the lifting operation, pipe hoisting operation or auxiliary installation operation of the pipeline. The clamping claw assembly and the lifting assembly are independent of each other and do not affect each other. The conversion between functions can be completed without disassembly. According to different working conditions and requirements, they can be switched at will to complete the operation task.

[0040] In summary, the integrated folding design of the lifting assembly and the gripper assembly provides a high degree of integration, enabling both lifting and pipe grabbing functions without requiring disassembly or assembly, without affecting the vehicle's overall performance and passability. The system can directly adapt to different material lifting operations, both for material lifting and for auxiliary pipe installation. It is convenient to use and highly safe. Furthermore, the mechanical claw lifting assembly 3 is powered and stabilized by the explosion-proof diesel engine crawler transporter body 1. The operation is fully hydraulically controlled, resulting in stable output, high safety, and smooth operation. The lifting and grabbing functions can be quickly switched between and can be operated independently, allowing for rapid adjustment based on complex working conditions and requirements. Furthermore, the structure is flexible, with the lifting assembly capable of 360° horizontal rotation, vertical lift, and free extension and retraction within a set range. The mechanical claw 8 can rotate 360° vertically and 360° left and right, coordinating with the lifting assembly to meet the requirements of different working conditions. When not in use, the mechanical claw 8 can be retracted to be flush with the lifting arm without affecting the lifting function.
