Description

Technical Field

[0001] This utility model relates to the field of lifting and loading machinery technology, specifically to an automatic mobile hydraulic lifting platform. Background Technology

[0002] A hydraulic lifting platform is a multi-functional lifting and loading / unloading machine, mainly used in engineering, warehouses, parking lots, docks, high-altitude operations and maintenance, etc. The lifting system of the lifting platform is driven by hydraulics, hence the name hydraulic lifting platform.

[0003] Chinese patent application CN211570005U discloses an automatic mobile hydraulic lifting platform, including a mounting box. A motor is installed inside the mounting box, and a drive gear is mounted on the output end of the motor. Driven gears mesh on both sides of the drive gear, and connecting rods are fixed to each driven gear. These connecting rods extend to the outside of the mounting box and are equipped with moving wheels. A base plate is provided on the top of the mounting box, and sliding rods are evenly installed on the bottom of the base plate, extending into the interior of the mounting box. Limit blocks are fixed to the bottom ends of the sliding rods. The springs between the base plate and the mounting box dampen vibrations during movement, reducing device shaking and ensuring the stability of the top plate, thus improving device safety. Push plates on both sides of the base plate can push away large obstacles during movement, ensuring linear and smooth movement of the device. Although the push plate can push away large pieces of gravel that cannot be blown away by the exhaust port, the gravel will stop in front of the push plate and slowly detach from it as the push plate moves forward. If too much gravel accumulates, it will undoubtedly affect the walking speed of the hydraulic lifting platform. Utility Model Content

[0036] The working principle and beneficial effects of the above technical solution are as follows:

[0037] This utility model discloses an automatic mobile hydraulic lifting platform. A hydraulic lift 10 is used for lifting goods. A traveling component 13 drives a fixed platform 12, the hydraulic lift 10 located on the fixed platform 12, and a lifting platform 11 located on the hydraulic lift 10. An air blowing component 16 blows away small pieces of gravel. A triangular push plate 14 located at the front end of the traveling direction of the fixed platform 12 pushes larger pieces of gravel. A gravel crushing rod component 15 crushes the large pieces of gravel pushed by the triangular push plate 14 into smaller pieces. The air blowing component 16 then continues to blow away the smaller pieces of gravel. This utility model provides an automatic mobile hydraulic lifting platform where the gravel crushing rod component 15 crushes the large pieces of gravel pushed by the triangular push plate 14 into smaller pieces, and the air blowing component 16 continues to blow away the smaller pieces of gravel. This solves the problem of excessive gravel accumulation affecting the traveling speed of the hydraulic lifting platform.

[0038] In one embodiment, the bottom end of the fixed platform 12 and the walking assembly 13 are connected by multiple spring columns 17.

[0039] The beneficial effects of the above technical solution are as follows:

[0040] The spring column 17 serves to reduce vibration.

[0041] In one embodiment, the walking component 13 includes:

[0042] The lower mounting shell 18 is a square box with an open bottom and is mounted on the bottom of the fixed platform 12.

[0043] Roller assemblies: Two sets of roller assemblies are mounted opposite each other on the side of the lower housing 18, and the crushing rod assembly 15 is connected to each set of roller assemblies.

[0044] The working principle and beneficial effects of the above technical solution are as follows:
