Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting equipment adjustment device. Background Technology

[0002] Lifting equipment is a type of mechanical equipment used for vertical lifting, horizontal movement, and installation of heavy objects. It is widely used in construction, industry, logistics, and energy sectors. Its core function is to achieve precise handling and positioning of heavy objects through mechanical force. Different operating environments require different lifting equipment. The selection of lifting equipment is a key aspect of lifting projects, and it is necessary to comprehensively consider the operating environment, load characteristics, economy, and safety. For example, small gantry cranes are often used in workshops, warehouses, logistics centers, and construction sites, taking into account the usage requirements.

[0003] Small gantry cranes are lightweight and compact lifting equipment that combines the span advantage of gantry cranes with the flexibility of small equipment. Existing small gantry cranes generally adopt a simple structure with an electric hoist suspended from the main beam. The lifting height is limited by the frame height and cannot be well adjusted.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5The present invention provides an embodiment as follows: To achieve the above objectives, the present invention adopts the following technical solution: A hoisting equipment adjustment device includes a support column 1, a connecting block 2 19 fixedly connected to the top of the support column 1, a support column 20 fixedly connected to the top of the connecting block 2 19, a limiting block 3 fixedly connected to the top of the support column 20, a rotating shaft 2 4 rotatably connected to the inner wall of the limiting block 3, a crossbeam 5 fixedly connected to the outer wall of the rotating shaft 2 4, a rotating shaft 3 6 fixedly connected to the right side of the crossbeam 5, a limiting block 2 7 rotatably connected to the outer wall of the rotating shaft 3 6, a crossbeam 2 8 fixedly connected to the right side of the limiting block 2 7, a protective shell 9 fixedly connected to the bottom of the crossbeam 2 8, a base 22 fixedly connected to the bottom of the support column 1, and a retraction mechanism 2 provided on both the left and right sides of the base 22. The retraction mechanism 2 is used to retract the wheels to improve the load-bearing capacity.

[0032] Specifically, the limiting block 3 limits and supports the rotation of the rotating shaft 4, the crossbeam 8 limits the crossbeams 5 and 8 so that they can be fixed at the lowest height, the protective shell 9 provides a fixed position for the lifting part, and the crossbeam 8 can maintain balance to prevent the two sides from shifting when adjusting the height and affecting the overall stability.

[0033] Please see the appendix Figure 2 and attached Figure 4 The retraction mechanism 2 includes a slide 201. The outer wall of the slide 201 is fixedly connected to the inner wall of the base 22. The inner wall of the base 22 is provided with a plurality of hidden grooves 202 near the edge. A plurality of sliders 203 are slidably connected to the inner wall of the slide 201. Limiting plates 204 are fixedly connected to the adjacent sides of the sliders 203. A rotating shaft 205 is rotatably connected to the inner wall of the hidden groove 202. A connecting block 206 is fixedly connected to the outer wall of the rotating shaft 205. A universal wheel 208 is fixedly connected to the bottom of the connecting block 206. A fixing piece 207 is fixedly connected to the top of the universal wheel 208.

[0034] Specifically, these hidden slots 202 provide storage space for the connecting block 206 and related components. When the casters 208 are not needed, the bottom of the base 22 can be made flat, increasing the contact area with the ground and improving the load-bearing capacity. The fixing plate 207 can fix the casters 208 so that they do not rotate.

[0035] Please see the appendix Figure 1 and attached Figure 5 A wire threading block 17 is fixedly connected to the outer wall of the limiting block 1 3, and a wire threading block 16 is fixedly connected to the top of the limiting block 2 7. A wire threading hole 15 is opened on the front side of the protective shell 9. A motor 10 is fixedly connected to the right side of the inner wall of the protective shell 9. A gear set 11 is fixedly connected to the output end of the motor 10. A wire reel 12 is fixedly connected to the output end of the gear set 11. A steel cable 13 is fixedly connected to the middle of the outer wall of the wire reel 12. A hook 14 is fixedly connected to the bottom end of the steel cable 13.

[0036] Specifically, the wire hole 15, the first wire block 16, and the second wire block 17 work together to guide the power cord and prevent the wires from becoming tangled and affecting operation. The gear set 11 plays the role of transmitting power and changing the transmission ratio. It can convert the high-speed rotational motion output by the motor 10 into a speed and torque suitable for the rotation of the coil 12, so that the coil 12 can reel in and unelute the steel cable 13 at a suitable speed and force.

[0037] Please see the appendix Figure 1 and attached Figure 2 The bottom end of the connecting block 2 19 is fixedly connected to the hook 2 18, the top of the base 22 is fixedly connected to multiple reinforcing strips 21, the outer wall of the coil 12 is fixedly connected to the left side of the inner wall of the protective shell 9 near the edge, and the top of the gear set 11 is fixedly connected to the middle of the inner wall of the protective shell 9.

[0038] Specifically, the reinforcing strip 21 provides lateral support for the support column 1, which can enhance the support capacity of the support column 1. The hook 2 18 can be used to hang tools, making it convenient for workers to access tools at any time and improving work efficiency.

[0039] Working principle: When the operator needs to adjust the height of the equipment, they only need to push the support column 1 from the left and right sides. At this time, the rotating shaft 6 and the protective shell 9 can only move upward under the limit of the limiting block 7. Specifically, the rotating shaft 4 and the rotating shaft 6 rotate counterclockwise, driving the crossbeam 8 to move upward. When it rises to the required height, stop pushing the support column 1 and fix the support column 1 in the position to quickly complete the height adjustment. To restore the height, simply stop pushing the support column 1, and the height will automatically return to normal under the action of gravity.

[0040] Since the bottom of the equipment needs to bear a large weight during use, and the caster wheel 208 generally cannot bear such a large weight, thus affecting the effectiveness of the equipment, when the operator uses the equipment for lifting, the slider 203 can be pushed to release the limit on the connecting block 206. By rotating the connecting block 206, the caster wheel 208 can be retracted to prevent the lifting weight from being concentrated on the caster wheel 208 and causing it to be damaged.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
