Heavy-load energy storage box traction device based on electric push rod

Abstract

The invention provides a heavy-load energy storage box traction device based on an electric push rod, and aims to solve the problem that an energy storage box cannot be transported by existing side zipper logistics transmission due to the fact that the energy storage box is too heavy and the axial thrust of side zipper transmission is small in the prior art. The device mainly comprises a limiting rail, a traction mechanism, a main body frame, a limiting mechanism, traction calipers and a push rod mechanism. According to the modularized electric traction device cooperatively working with the side zipper, accurate axial thrust is provided through the electric push rod, and the problems of insufficient thrust and dynamic instability in the transportation process of a heavy-load energy storage box are solved.

Description

Technical Field

[0001] This invention relates to the field of industrial logistics transportation equipment technology, and in particular to a heavy-duty energy storage box traction device based on an electric push rod. Background Technology

[0002] Traditional factory logistics uses standard side zippers to transfer containers. Since the production requirements of energy storage equipment are very similar to those of containers, the side zipper method of containers is used to transport energy storage boxes. However, considering the heavy load requirements of energy storage boxes and the limitations of side zipper transmission, some current side zipper logistics transmission methods cannot transport energy storage boxes.

[0003] Specifically, chain drives exhibit a unidirectional force characteristic; that is, side-pull chain drives primarily drive the load through the lateral tension of the chain, but the chain's longitudinal (traction direction) thrust is relatively weak. For heavy-load or long-distance transportation, the lateral friction and meshing force of the chain alone may not provide sufficient propulsion. Therefore, to combine existing container side-zipper logistics equipment for transporting heavier energy storage containers, the problem of insufficient axial thrust needs to be addressed. Summary of the Invention

[0004] This application addresses the shortcomings of the prior art by providing a modular electric traction device that works in conjunction with a side zipper. The device provides precise axial thrust through an electric push rod, thus solving the problems of insufficient thrust and dynamic instability during the transportation of heavy-duty energy storage boxes.

[0005] The technical solution adopted in this invention is as follows: A heavy-duty energy storage box traction device based on an electric push rod includes a limiting rail arranged on one side of the on-site side zipper transmission mechanism, a traction mechanism slidably arranged on the limiting rail, the traction mechanism including a main frame, a limiting mechanism arranged at the bottom of the main frame and cooperating with the limiting rail, a traction clamp arranged on one side of the main frame for attaching to the side zipper, and a push rod mechanism arranged at the top of the main frame for pushing or avoiding a non-powered trolley.

[0006] Furthermore, the cross-section of the limiting rail is an H-shaped steel rail.

[0007] Furthermore, the main frame includes roller cavities located at the front and rear, and a device cavity located in the middle; The limiting mechanism includes a planar roller horizontally disposed inside the front and rear roller cavities, the planar roller meshing with the upper surface of the H-beam rail; The limiting mechanism also includes wheel frames fixed on both sides of each set of roller cavities, and transverse guide wheels are installed on a set of wheel frames opposite to each other. The transverse guide wheels mesh with the vertical surface of the H-beam rail. A longitudinal guide wheel is mounted on a set of wheel frames in the middle, and the longitudinal guide wheel engages with the lower surface of the upper profile of the H-beam rail.

[0008] Furthermore, the traction caliper includes a side welding plate fixed to the side of the main frame. A base plate is fixed to the side welding plate by fasteners. A reinforcing rib is welded on the base plate. The back of the reinforcing rib is simultaneously welded and fixed to the main frame. Engaging claws are fixed below the side wall of the side welding plate.

[0009] Furthermore, the push rod mechanism includes an electric push rod located in the middle of the main frame. The working end of the electric push rod is movably hinged to the top of the main frame. A rotating shaft is provided inside the main frame. A push rod that rotates with the shaft is fixed on the rotating shaft. A hinge seat is provided coaxially on the rotating shaft. The swing end of the electric push rod is hinged to the hinge seat.

[0010] The advantages of this invention over the prior art are as follows: 1) Precise thrust compensation is possible: the electric actuator directly provides axial thrust, making up for the shortness of longitudinal thrust of the chain and increasing thrust; 2) Effectively enhances dynamic stability: Six-degree-of-freedom displacement is constrained by a triple guide wheel system in the plane, lateral and longitudinal directions, improving the ability to resist eccentric loads; the meshing pawls are rigidly engaged with the chain, eliminating the risk of slippage in traditional friction transmission; 3) Low maintenance cost: The modular design supports quick disassembly and assembly, replacing the complex oil circuit maintenance of the hydraulic system; the electric actuator has a long service life, significantly reducing downtime.

Limiting mechanism 22: Planar roller 221: meshes with the upper surface of the 244H-type steel rail and bears the load; Guide roller: installed in pairs on the side wall of the roller cavity 211, meshes with the vertical plane of the 244 rail to prevent lateral deviation; Longitudinal guide roller 224: installed in pairs in the middle, meshes with the lower surface of the 244 rail to prevent overturning; 3.
