Abstract

This invention discloses a hoisting device suitable for mining battery swapping vehicles, comprising a support assembly, a locking assembly, and a triggering assembly. The support assembly includes a support frame, the locking assembly includes a locking block, and the triggering assembly includes a handle and a trigger rod. During battery box hoisting, the support frame is aligned with the battery box frame, and the device descends. The locking head of the locking block abuts against the battery box frame. The trigger rod, through a linkage mechanism, drives the locking block to rotate. The support frame, linkage mechanism, and locking head form a lever-like mechanism. The rotation of the locking head allows the device to continue descending until the support frame abuts against the battery box frame. The locking head then rotates in the opposite direction, entering between the battery box frame and the box body. The locking head and support frame cooperate to fix the battery box, locking it under its own weight. After hoisting to the desired position, the locking block rotates, causing the locking head to disengage from the battery box frame, thus unlocking the battery box.

Description

Technical Field

[0001] This invention relates to the technical field of underground transportation equipment and its supporting facilities in coal mines, and in particular to a hoisting device suitable for mine battery swapping vehicles. Background Technology

[0002] With the increasing demands for safe production, energy conservation, emission reduction, and intelligent development in coal mines, the adoption of explosion-proof battery vehicles for underground auxiliary transportation is becoming a growing trend. Currently, explosion-proof battery vehicles used in underground coal mines are primarily for transporting personnel and materials. Powered by explosion-proof lithium batteries, they offer advantages such as zero emissions and low noise, significantly improving the underground working environment.

[0003] Currently, the range of explosion-proof lithium battery vehicles used in mining is difficult to meet the needs of operation in the entire mine shaft, and charging is not possible underground, causing "range anxiety" for drivers. The limitation of their range reduces the efficiency and attendance rate of vehicle use.

[0004] Battery swapping vehicles separate the vehicle from the battery, becoming one of the methods to solve range anxiety in battery-powered vehicles.

[0005] Existing ground-based battery swapping vehicles can perform battery swapping using mature battery swapping station systems, which employ multiple sensors and electric or hydraulic actuators to achieve fully automated battery grabbing and replacement. However, there are currently no mature battery swapping standards or solutions for mining vehicles, and battery swapping must be completed within the existing driving environment.

[0006] Therefore, how to change the current situation where there is no dedicated battery hoisting device for mining battery swapping vehicles suitable for the existing operating environment has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The purpose of this invention is to provide a hoisting device suitable for mining battery swapping vehicles, so as to solve the problems existing in the prior art, provide convenient conditions for battery swapping of mining vehicles, and improve the working efficiency of mining battery swapping vehicles.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This invention provides a hoisting device suitable for mining battery swapping vehicles, comprising a support assembly 100, a locking assembly 200, and a triggering assembly 300. The support assembly 100 includes a support frame 1, which abuts against the frame of the battery box 16 to be hoisted. The locking assembly 200 includes a locking block 2, which is hinged to the inner wall of the support frame 1. The locking block 2 has a locking head 3, which extends between the frame and the body of the battery box 16. The locking head 3 cooperates with the support frame 1 to fix the frame of the battery box 16. The triggering assembly 300 includes a handle 4 and a trigger rod 5. The handle 4 is connected to the trigger rod 5, which is slidably connected to the support frame 1. The trigger rod 5 is connected to the locking block 2 via a linkage mechanism. The locking block 2 is hinged to the linkage mechanism. One end of the locking block 2 is connected to the locking head 3, and the other end is hinged to the linkage mechanism. The middle part of the locking block 2 is hinged to the support frame 1. The trigger rod 5 can drive the locking block 2 to rotate.

[0037] The hoisting device of this invention, applicable to mining battery swapping vehicles, involves aligning the support frame 1 with the frame of the battery box 16 during hoisting. As the device descends, the locking head 3 of the locking block 2 abuts against the frame of the battery box 16, preventing further descent. The handle 4 then drives the trigger rod 5, which in turn rotates the locking block 2 via a linkage mechanism. The support frame 1, linkage mechanism, and locking head 3 form a lever-like mechanism. Please refer to [reference needed]. Figure 3 and Figure 4 The locking head 3 rotates, allowing the device to continue descending until the support frame 1 abuts against the frame of the battery box 16. The locking head 3 then rotates in the opposite direction and enters between the frame and the body of the battery box 16. The locking head 3 and the support frame 1 cooperate to fix the battery box 16, locking it under the weight of the battery box 16. After the battery box 16 is hoisted into place, the handle 4 drives the trigger rod 5 and the linkage mechanism to move, causing the locking block 2 to rotate, thus disengaging the locking head 3 from the frame of the battery box 16 and unlocking the battery box 16. This improves the ease of hoisting the battery box 16, provides convenient conditions for battery swapping in mining vehicles, and helps improve the working efficiency of mining vehicles.

[0038] The linkage mechanism includes a spatial reversing block 6, a first link 7, and a second link 8, as detailed below. Figure 2The space reversing block 6 is slidably connected to the support frame 1. The sliding direction of the space reversing block 6 is perpendicular to the plane of the support frame 1. The space reversing block 6 is connected to the locking block 2 by the first connecting rod 7. One end of the first connecting rod 7 is hinged to the locking block 2, and the other end of the first connecting rod 7 is hinged to the space reversing block 6. The space reversing block 6 is connected to the trigger rod 5 by the second connecting rod 8. One end of the second connecting rod 8 is hinged to the trigger rod 5, and the other end of the second connecting rod 8 is hinged to the space reversing block 6. The handle 4 can push the trigger rod 5, which in turn drives the space reversing block 6 to slide vertically via the second connecting rod 8. The space reversing block 6 uses the first connecting rod 7 to push the locking block 2 to rotate, so that the locking head 3 of the locking block 2 can shift towards the center of the support frame 1, allowing the device to fall smoothly. After the support frame 1 abuts against the frame of the battery box 16, the device falls into place, the locking block 2 and the trigger rod 5 reset, and the locking head 3 enters between the frame and the body of the battery box 16. The locking block 2 and the support frame 1 cooperate to lock the battery box 16. During the hoisting process, the weight of the battery box 16 ensures the locking reliability of the locking block 2 and improves the working stability of the device. The trigger rod 5 uses a linkage mechanism to drive the locking block 2 to rotate, which has a simple structure and reliable movement.

[0039] In this specific embodiment, there are four sets of locking components 200. The lines connecting the locking components 200 form a rectangle. The locking components 200 are symmetrically arranged with the trigger rod 5 as the axis. Each space reversing block 6 connects two locking blocks 2. The two space reversing blocks 6 are connected by a third connecting rod 9. The two space reversing blocks 6 are respectively hinged to the third connecting rod 9. The setting of four sets of locking components 200 improves the uniformity of force on the battery box 16 during hoisting and further improves the hoisting safety factor.

[0040] To facilitate the installation and fixation of the space reversing block 6, the support assembly 100 also includes a support rod 10, which is connected to the support frame 1. The support rod 10 is connected to a support shaft 11, and the axis of the support shaft 11 is perpendicular to the plane of the support frame 1. The space reversing block 6 is slidably connected to the support shaft 11. The space reversing block 6 slides up and down along the support shaft 11, thereby driving the locking block 2 to rotate and completing the locking and unlocking of the battery box 16.

[0041] In practical applications, the support rod 10 can be set as an I-beam. The support rod 10 is connected to the support frame 1, which improves the overall structure of the support assembly 100. While facilitating the connection between the support shaft 11 and the space reversing block 6, it simplifies the structure of the support assembly 100, reduces the weight of the device itself, and improves the flexibility and adaptability of the device.

[0042] Specifically, the trigger assembly 300 also includes a handle link 12. One end of the handle link 12 is hinged to the handle 4, and the other end of the handle link 12 is hinged to the support frame 1. One end of the handle 4 is hinged to the trigger rod 5, and the other end of the handle 4 is a free end. The hinge point between the handle 4 and the handle link 12 is located between the hinge point between the handle 4 and the trigger rod 5 and the free end of the handle 4. The handle 4, the handle link 12, the trigger rod 5, and the support frame 1 form a crank-slider mechanism. Rotating the handle 4 can drive the trigger rod 5 to move, and then the trigger rod 5 can drive the locking assembly 200 to work. This improves the ease of operation of the device while ensuring the reliability of the movement of the trigger rod 5.

[0043] To further improve the reliability of the trigger rod 5, the trigger rod 5 is a square rod, and the support frame 1 has a square hole that matches the trigger rod 5. The trigger rod 5 can slide through the square hole and connect to the second connecting rod 8. The square rod and square hole effectively prevent the trigger rod 5 from rotating out of position. In addition, the handle connecting rod 12 and the trigger rod 5 are provided with positioning holes 14 that allow the positioning pin 13 to pass through. When the locking block 2 is locked, the positioning pin 13 can be passed through the positioning holes 14 on the handle connecting rod 12 and the trigger rod 5 to lock the trigger rod 5, further improving the working safety factor of the device.

[0044] More specifically, the support assembly 100 also includes a guide block 15, which is connected to the support frame 1. The guide block 15 has a guide slope that is inclined from top to bottom away from the support frame 1. During the lowering of the device, the guide slope of the guide block 15 can play a guiding role to prevent the device from tilting and to enable the support frame 1 to be aligned with the frame of the battery box 16, thus facilitating the operation of the subsequent locking assembly 200.

[0045] In this specific embodiment, there are multiple guide blocks 15, and the lines connecting the guide blocks 15 form a rectangle to achieve guidance in various directions. Some guide blocks 15 are connected to the inner sidewall of the support frame 1, and the remaining guide blocks 15 are connected to the outer sidewall of the support frame 1. This helps to save working space and avoid affecting the normal operation of the locking assembly 200.

[0046] Furthermore, the locking head 3 has a locking surface and a relief slope. The locking surface is a plane parallel to the bottom surface of the frame of the battery box 16. The locking surface is located above the relief slope. The relief slope is inclined from top to bottom in a direction away from the support frame 1. During the downward movement of the device, the frame of the battery box 16 contacts the relief slope of the locking head 3, which can push the locking block 2 to rotate. The locking block 2 can be rotated without the trigger rod 5, thus avoiding the phenomenon of the locking block 2 being blocked. After the locking head 3 extends between the frame and the box body of the battery box 16, the locking plane contacts the bottom of the frame of the battery box 16, thereby locking the battery box 16.

[0047] The present invention relates to a hoisting device for mining battery swapping vehicles. During the hoisting process, guided by the avoidance slope of the locking head 3, the locking block 2 rotates and comes into tangential contact with the inside of the battery box 16 frame. Until it passes the lower plane of the battery box 16 frame, the weight of the locking head 3 is much greater than the upper weight. The locking block 2 falls back and rotates due to its own weight, thus locking the battery box 16. The battery box 16 is also passively locked due to its own weight, improving the ease of operation and adaptability of the device. When the device is fully positioned over the battery box 16... After locking, the positioning pin 13 passes through the positioning hole 14 on the handle connecting rod 12 and the trigger rod 5, restricting the device to a rigid connection, thereby limiting the rotation of the locking block 2 and ensuring the device locks the battery box 16, improving the reliability of locking and the safety during operation. In addition, when unlocking the battery box 16, the rotation of the locking block 2 can be completed by rotating the handle 4 and the transmission of the linkage mechanism, thereby unlocking the battery box 16. The unlocking operation of the battery box 16 can be carried out manually, greatly improving the convenience and adaptability of unlocking.

[0048] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
