Technical Field
[0001] This utility model relates to a new type of tracked pipeline installation grabber for mining, belonging to the field of coal mine pipeline installation technology. Background Technology
[0002] The existing underground pipeline auxiliary installation vehicle in coal mines only has one pipeline grabbing robotic arm, which requires workers to be equipped with an aerial platform during operation, making the operation cumbersome; the minimum range of motion of the robotic arm is too large, making it unable to operate in narrow underground roadways. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a new type of tracked pipeline installation grabber for mining, used for the installation of gas drainage pipelines in coal mine roadways.
[0004] This utility model is achieved through the following technical solution: a new type of mining tracked pipeline installation and lifting vehicle, including a vehicle body, a chassis assembly at the bottom of the vehicle body, and a mechanical arm assembly, a standing platform, a walking operation platform assembly and a pipeline lifting platform on the vehicle body.
[0005] The chassis assembly is constructed from welded and bolted steel plates. A track assembly is located at the bottom of the chassis assembly, its design providing excellent off-road performance and ground traction, enabling it to adapt to complex underground terrain. The robotic arm assembly consists of a slewing assembly, a gripping column, hydraulic cylinders, and a pipe-gripping component. A personnel platform is located on one side of the vehicle body, providing standing space for operators. The pipe-lifting platform is used for lifting and laying pipes.
[0006] The robotic arm assembly is a 6-DOF robotic arm, including a slide assembly, a rotary mechanism I, a primary arm I, a secondary arm I, a main arm cylinder, a rotating support, and a gripper assembly. The slide assembly is mounted on the vehicle body and connected to the rotary mechanism I. The rotary mechanism I is connected to the primary arm I and the main arm cylinder. The main arm cylinder is connected to the rotary mechanism I and the secondary arm I. The secondary arm I is connected to the rotating support. The gripper assembly is mounted on the rotating support.
[0007] The rotary mechanism I is connected and fixed to the slide assembly via hexagonal bolts and spring washers. The rotary mechanism I can rotate on the slide assembly. The boom cylinder provides power for the movement of the secondary boom I, enabling its angle change. The primary boom I is connected to the rotary mechanism I via a boom pivot pin and a positioning sleeve, and can rotate around the connection point.
[0008] The manned platform includes a rotating mechanism II, a base, a balance arm I, a primary arm II, a balance connecting frame, a balance arm II, a secondary arm II, and a manned platform. The rotating mechanism II is fixed to the vehicle body and is connected to the base via hexagonal bolts and spring washers. The balance arm I is connected to the balance connecting frame and the base via locating pins. The balance connecting frame is connected to the primary arm II and the secondary arm II to maintain the balance of the robotic arm during movement. The balance arm II is connected to the balance connecting frame and the manned platform, and the manned platform is connected to the secondary arm II.
[0009] The base and the balance connecting frame are connected to a hydraulic cylinder, and the balance connecting frame and the secondary arm II are connected to a hydraulic cylinder. The hydraulic cylinder extends and retracts to drive the primary arm II and the secondary arm II to rotate around the connection point, thereby realizing the extension, retraction, and angle adjustment of the robotic arm to change the working range and height of the platform.
[0010] The lifting pipeline platform includes a lifting rail base, scissor arms I, II, III, IV, and a frame platform. The lifting rail base is connected to scissor arms II via positioning pins. Scissor arms I are provided with a pulley positioning shaft and pulleys at their bottom. Scissor arms I are connected to the lifting rail base via the pulley positioning shaft and pulleys, allowing scissor arms I to slide on the lifting rail base. Scissor arms II and III are connected to lifting cylinders.
[0011] The scissor arms I, II, III, and IV, driven by the lifting cylinder, extend and retract by rotating the hinge points, thereby changing the height position of the frame platform.
[0012] The vehicle body also houses a powertrain, which uses compressed air for power.
[0013] The beneficial effects of this utility model are: it can work and operate in narrow underground tunnels, its working range is small, and only two workers are needed to operate and install the pipeline. The maximum working height can reach 4 meters. Its power source is compressed gas, which can be safely operated in environments containing gas. Attached Figure Description
