Description

Technical Field

[0001] The utility model relates to the field of hoisting, in particular to a heavy truck battery box hoist. Background Art

[0002] With the development of society, the use of electric heavy trucks will become more extensive. The existing heavy truck battery replacement equipment on the market has the following main disadvantages: 1. The lifting time of the lifting equipment is long, which affects the battery replacement rhythm; 2. The requirements for the site and the use environment are relatively stringent; 3. The equipment cost of the visual intelligent heavy-duty lifting equipment is high, the control is complex, the maintenance cost is too high, the application range is low, and it cannot be used in harsh environments such as wind, sand, and saline-alkali. In addition, most of the existing lifting equipment is fixed, and the grabbing is often achieved through the movement of the main body of the equipment, which takes a long time and is bulky. These factors have seriously restricted the development of electric heavy trucks.

[0003] Patent publication number CN217808305U discloses a heavy-duty truck battery-exchange hanger, which includes a support frame, two mounting frames, two hook assemblies and two adjustment structures. The support frame is extended in the left and right directions, and its upper end is used to connect the lifting equipment; the two mounting frames are installed at intervals in the left and right directions at the lower end of the support frame; the two hook assemblies are respectively installed on the two mounting frames, and each of the hook assemblies includes a driving member and two hooks. The two hooks are arranged at intervals in the front-to-back direction and are rotatably installed on the corresponding mounting frames along the front-to-back axis. The driving member is used to drive the two hooks to rotate synchronously, and the two hooks have a first state for separating from the heavy-duty truck battery box and a second state for engaging with the heavy-duty truck battery box in their rotation stroke. The hoist can solve the problem that the existing battery exchange hoist cannot flexibly adjust the distance between the hooks according to the width of the battery box. However, the hooks of the hoist are all arranged on the outer periphery of the rotating shaft and are matched with the rotating shaft to stop rotation. The hooks only have a first state for separating from the heavy-duty truck battery box and a second state for engaging with the heavy-duty truck battery box in their rotation stroke. At the same time, when the hook is directly above the heavy-duty truck battery box when descending, there is no guide structure, and manual height adjustment is required, which is prone to inaccurate positioning. Utility Model Content

[0004] The purpose of the utility model is to provide a heavy truck battery box hoist in order to overcome the defects of the existing fixed hoist in the prior art that the grabbing is performed by the movement of the main body, resulting in a long grabbing action and a cumbersome action.

[0089] In this embodiment, if Figures 4 to 6 As shown, the rotation drive mechanism 3 is provided with two groups, which are respectively located at the two ends of the mounting base plate 1. The rotation drive mechanism 3 includes:

[0090] A motor mounting plate 302 connected to the mounting base plate 1;

[0091] A motor reducer 301 connected to the motor mounting plate 302 and outputting power;

[0092] A drive shaft 303 connected to the motor reducer 301;

[0093] And first bevel gears 305 are arranged at both ends of the driving shaft 303 .

[0094] In this embodiment, if Figures 4 to 7 As shown, the hook assembly 4 has two groups, which are respectively installed at the two ends of the bottom of the mounting base plate 1, each group has two hooks, which are respectively connected to the two ends of the driving shaft 303 of the rotating drive mechanism 3. The hook assembly 4 includes:

[0095] A rotating base 403 fixed on the mounting base plate 1;

[0096] A second bevel gear 407 meshing with the first bevel gear 305 to convert the lateral rotation of the drive shaft 303 into a vertical rotation;

[0097] A rotating shaft 404 passing through the rotating base 403 and rotating;

[0098] A hook 401 connected to the rotating shaft 404 and rotating therewith;

[0099] A bearing 406 and a bearing seat 409 connecting the rotating shaft 404 to the rotating base 403;

[0100] A shaft sleeve 408 sleeved on the rotating shaft 404;

[0101] A position sensing sheet 410 located on the rotating shaft 404 for detecting whether the rotation angle is in position;

[0102] A protective cover 405 for preventing external pollution is located outside the rotating shaft 404. A wear-resistant plate 402 is also provided on the hook 401 to increase the friction between the heavy truck battery box 10 and the hook 401 to prevent it from sliding off and also reduce the damage of the hook 401.

[0103] In this embodiment, the hook 401 is initially parallel to the frame of the heavy truck battery box 10. When the in-position sensor 410 senses that the rotation angle reaches 90 degrees, the rotation-in-position switch 8 is triggered, and the hook 401 rotates to the position.

[0104] In this embodiment, there are six guide mechanisms 5, which are distributed in a rectangular shape at the bottom of the mounting base plate 1. The guide mechanism 5 is cylindrical in shape, and has a chamfered surface on the outside, which facilitates the sling to enter the top of the heavy truck battery box 10. When the guide mechanism 5 is lowered to a certain height, the in-position travel switch 7 is triggered, and the sling is in place and cannot be lowered.

[0105] In this embodiment, the sling also includes a plurality of limiting mechanisms 6 located next to the hook assembly 4, which are used to further limit the descending height of the sling. When the limiting mechanisms 6 are in contact with the top of the frame of the heavy truck battery box 10, the sling can no longer descend, thereby preventing the sling from colliding and being damaged with the heavy truck battery box 10.

[0106] The working process and principle of the spreader are as follows:

[0107] The robot arm of the lifting equipment is connected to the sling through a flexible connecting mechanism 2, and the sling is moved to the top of the heavy truck battery box 10. The robot arm of the lifting equipment begins to descend, and the sling passes through the inclined surface of the guide mechanism 5, so that the sling enters the top of the heavy truck battery box 10. Since the flexible connecting mechanism 2 on the sling allows the sling to swing, the sling will not be stuck on the top of the heavy truck battery box 10, and continues to descend until the sling triggers the in-place travel switch 7. At this time, the sling is in place and the robot arm stops descending.

[0108] At this time, the hook 401 is parallel to the frame of the heavy truck battery box 10 to prevent the hook 401 from colliding with the frame during the descent. After the hoist is in place, the rotary drive mechanism 3 drives the hook assembly 4 to rotate. When the hook 401 rotates 90 degrees, that is, the hook 401 is perpendicular to the frame of the heavy truck battery box 10 and can clamp the frame of the heavy truck battery box 10, the rotation to position switch 8 is triggered, and the hook 401 is rotated to position. At this time, the robot arm of the hoisting equipment begins to rise to complete the work of grabbing the heavy truck battery box 10.

[0109] After the lifted heavy truck battery box 10 arrives at the placement position, the mechanical arm of the lifting equipment begins to descend. After the heavy truck battery box 10 falls into place, the hoist continues to descend until the position travel switch 7 is triggered, and the descent of the hoist stops. At this time, the hook assembly 4 is driven by the rotation drive mechanism 3 to start reverse rotation, and the hook 401 rotates back to the original position and triggers the rotation into place switch 8, and the mechanical arm rises and leaves, completing the placement work.

[0110] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
