Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the mining crawler lift includes a lifting platform 1, a lifting arm 2, a lifting cylinder 3, a frame 4, and a crawler track 5. In the figure, multiple lifting lugs 101 are symmetrically arranged on both sides of the lifting platform 1. The lifting platform 1 is used as an aerial work platform and a transport platform. Specifically, two sets of top chutes 102 are symmetrically arranged on the inner side of the bottom of the lifting platform 1, and a top shaft hole 103 is formed at one end of the top chutes 102.

[0021] In the figure, the lifting arm 2 includes two sets of main arms 201 and auxiliary arms 202. The main arms 201 and auxiliary arms 202 are arranged crosswise to form a scissor-fork structure. The middle parts of the main arms 201 and auxiliary arms 202 are connected by a central shaft 203, wherein: the tops of the two main arms 201 are installed in the top shaft hole 103 through the main top rotating shaft 204, the middle parts of the two main arms 201 are installed with lifting shafts 205, and the bottoms of the two main arms 201 are installed with main sliding wheels 207 through the main bottom rotating shaft 206. The main sliding wheels 207 can be The two auxiliary arms 202 are movably mounted in the bottom chute 401 at the front end of the vehicle frame 4. Auxiliary sliding wheels 210 are mounted on the top of the two auxiliary arms 202 via auxiliary top rotating shafts 209. The auxiliary sliding wheels 210 are movably mounted in the top chute 102. The bottoms of the two auxiliary arms 202 are mounted on the rear end of the vehicle frame 4 via auxiliary bottom rotating shafts 211. The cylinder tails 301 of the two lifting cylinders 3 are swingably mounted on the auxiliary bottom rotating shafts 211. The ends of the telescopic rods 302 of the lifting cylinders 3 are connected to the lifting shaft 205 via shaft sleeves 303. Specifically, one or more reinforcement rods 208 are also installed between the two main arms 201.

[0022] During actual operation, when the lifting cylinder extends, it first drives the lifting shaft 205 upward, then drives the main arm 201 and auxiliary arm 202 to rise synchronously. Because the main arm 201 and auxiliary arm 202 are of the same length, their top positions can also remain consistent. When the lifting cylinder retracts, it similarly drives the main arm 201 and auxiliary arm 202 to descend synchronously. Because the bottom end of the main arm is connected to the frame via a sliding wheel and chute structure, and the top end of the auxiliary arm is connected to the lifting platform via a sliding wheel and chute structure, this connection scheme effectively ensures the smooth raising and lowering of the lifting platform, keeping the lifting platform in a constant horizontal working state.

The hydraulic system 402 includes a gear pump, a hydraulic oil tank, and a multi-way valve. The hydraulic system 402 is used to provide hydraulic oil to the lifting cylinder, the leg cylinder, etc. Specifically, the crawler travel device 5 includes a track 501, track wheels 502, and a hydraulic motor 503. Among them, the four track wheels 502 are symmetrically arranged on both sides of the frame 4. The two track wheels 502 on the front side are driving wheels driven by the hydraulic motor 503, and the two track wheels 502 on the front side are follower wheels. The track 501 is mounted on the driving wheels and the follower wheels.

[0024] It should be noted that H-shaped outrigger oil cylinders 6 are provided at the four corners of the frame 4 , and the four H-shaped outrigger oil cylinders 6 are used for supporting and leveling the equipment.

[0025] In practical application, this lift is equipped with a crawler track system, allowing it to adapt to the complex road conditions within mines. Furthermore, the lift utilizes a scissor-type structure with a cross-arm and auxiliary arm to reliably raise and lower the lift platform, meeting various transport and construction heights. Lifting speed and height can be precisely controlled by controlling the lift cylinder.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
