Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a crane with an anti-deviation wheel assembly. Background Technology

[0002] Cranes, as indispensable core equipment in engineering construction, port loading and unloading, logistics and warehousing, etc., can efficiently complete the vertical lifting and horizontal handling of heavy cargo by means of their powerful lifting, luffing, slewing and running mechanisms working together. In bridge construction, cranes can accurately lift prefabricated components; in port terminals, they bear the heavy responsibility of rapid container loading and unloading; in large factories, they are a key force in the assembly of heavy equipment. When existing cranes work in different sites, due to uneven and complex terrain, the crane wheel assembly is prone to misalignment due to uneven force. This not only seriously affects the normal operating efficiency of the crane, but may also cause serious safety accidents such as cargo swaying, equipment imbalance, or even overturning, which greatly threaten personnel safety and project progress. Therefore, this utility model proposes a crane with anti-misalignment wheel assembly. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background art where, when cranes operate in different locations, the wheel assembly of the crane is prone to shifting due to uneven force on complex terrain such as slopes, bumps, and depressions. This not only seriously affects the normal operating efficiency of the crane, but may also cause major safety accidents such as cargo shaking, equipment imbalance, or even overturning, greatly threatening personnel safety and project progress. The invention proposes a crane with anti-shift wheel assembly.

[0004] The technical solution of this utility model is as follows: A crane with an anti-deviation wheel assembly includes: a crossbeam, on which a hook assembly for lifting goods is slidably disposed, and connecting plates are fixedly disposed on the bottom surfaces of both ends of the crossbeam; two columns for support are disposed directly below the crossbeam, the upper ends of the columns are sleeved with the connecting plates, a connecting sleeve is sleeved on the outer wall of the columns, connecting plates are fixedly disposed on both sides of the connecting sleeve, a set of support legs is disposed between the connecting plates, and a limiting assembly for preventing the wheel assembly from deviating is disposed at the lower end of the support legs.

[0028] Example

[0029] like Figures 1 to 3 As shown, this utility model proposes a crane with an anti-deviation wheel assembly, comprising: a crossbeam 1, which is designed in an "I" shape to provide good support strength; a hook assembly 2 for lifting goods is slidably mounted on the crossbeam 1, and the hook assembly 2 includes a hook frame, with a fixed pulley block installed on the top of the hook frame. The fixed pulley block is rotatably connected to the hook frame via bearings, which can reduce the frictional resistance of the wire rope during lifting. The fixed pulley block is connected to the crane's winch via a high-strength wire rope. The hoist's winding and unwinding actions control the lifting and lowering of the hook assembly. A hook is installed below the hook frame. The hook is made using a forging process and is equipped with an anti-disengagement device at the hook opening to prevent the goods from accidentally falling off during the lifting process. Guide wheels are also provided on both sides of the hook frame. The guide wheels contact the edge of the slide rail on the crossbeam 1 to ensure that the hook assembly 2 moves stably on the crossbeam 1. Connecting pieces 3 are fixedly installed on the bottom surfaces of both ends of the crossbeam 1, and the connecting pieces 3 are bent at 90 degrees to stably connect the crossbeam 1 to the column 4.

[0030] Furthermore, two support columns 4 are provided directly below the crossbeam 1, and the columns 4 are symmetrically arranged. The upper end of the column 4 is sleeved with the connecting piece 3. The outer wall of the column 4 is sleeved with a connecting sleeve 5. The connecting sleeve 5 and the column 4 are fixedly connected by a limiting bolt. Connecting plates 6 are fixedly arranged on both sides of the connecting sleeve 5, and the connecting plates 6 are symmetrically arranged. A set of support legs 7 is arranged between the connecting plates 6, and the support legs 7 are inclined. The first reinforcing piece 12 is provided on both sides of the support leg 7, and the second reinforcing piece 13 is provided on one side of the support leg 7. The first reinforcing piece 12 and the second reinforcing piece 13 provide stable support for the support leg 7, ensuring the stability of the support leg 7.

[0031] like Figure 4 and Figure 5 As shown, the lower end of the outrigger 7 is provided with a limiting component 8 for preventing wheel assembly displacement. The limiting component 8 includes a fixing plate 801 fixedly mounted on the bottom surface of the outrigger 7, and the outrigger 7 and the fixing plate 801 are welded together to ensure the stability of the connection. A reinforcing rib 14 is provided at the connection between the outrigger 7 and the fixing plate 801 to increase the stability of the connection between the outrigger 7 and the fixing plate 801. The bottom surface of the fixing plate 801 is fixed with wheels 802 by bolts for moving the crane to different positions for lifting. The first adjusting screw 803 and the second adjusting screw 804 are connected through the groove. The lower end of the first adjusting screw 803 is rotatably provided with a first connecting seat 805. The lower end of the first connecting seat 805 is rotatably provided with a fixed seat 806 through a fixing pin, which can ensure that the first connecting seat 805 and the fixed seat 806 are rotatably connected. The bottom surface of the fixed seat 806 is fixedly provided with a limit plate 807. The bottom surface of the limit plate 807 is provided with multiple limit protrusions 15 to increase the friction between the limit plate 807 and the ground and prevent the wheel 802 from deviating.

[0032] Secondly, a guide frame 808 is fixedly installed on the upper surface of the limiting plate 807. A guide groove is opened on one side of the guide frame 808, and there are two guide frames 808, which are arranged symmetrically. A second connecting seat 809 is provided between the guide frames 808. The upper end of the second connecting seat 809 is rotatably connected to the second adjusting screw 804, which facilitates the displacement of the second connecting seat 809. Sliding blocks 810 are fixedly installed on both sides of the second connecting seat 809. The sliding blocks 810 are movably sleeved with the second connecting seat 809 to ensure that the limiting plate 807 deflects at an angle, so as to fit tightly with the ground and thus stably limit the wheel 802.

[0033] Furthermore, a first mounting base 9 is fixedly installed on the bottom surface of the crossbeam 1, and a second mounting base 10 is fixedly installed on one side of the connecting sleeve 5. A hydraulic cylinder 11 is installed between the second mounting base 10 and the first mounting base 9. The output end of the hydraulic cylinder 11 pushes the first mounting base 9, thereby making it easier to adjust the lifting height of the hook assembly 2 on the crossbeam 1.

[0034] In this embodiment, the crane is moved above the goods to be lifted using wheels 802. The hydraulic cylinder 11 between the crossbeam 1 and the connecting sleeve 5 is activated. The output end of the hydraulic cylinder 11 drives the column 4 to slide up and down along the connecting sleeve 5, causing the column 4 to move the crossbeam 1 up and down. The crossbeam 1 then causes the hook assembly 2 to rise or fall accordingly until the hook assembly 2 reaches a suitable height for lifting the goods. After adjustment, the column 4 and the connecting sleeve 5 are tightened with bolts to ensure stability during lifting.

[0035] After the crane is adjusted to the appropriate lifting height, the first adjusting screw 803 and the second adjusting screw 804 on the fixed plate 801 are rotated. Since the first adjusting screw 803 is threadedly engaged with the fixed plate 801, it drives the first connecting seat 805 connected to its lower end to move vertically downwards. This, in turn, drives the limiting plate 807 downwards via the first connecting seat 805 and the fixed seat 806, causing one end of the limiting plate 807 to contact the ground first. Subsequently, the second adjusting screw 804 is also threadedly engaged with the fixed plate 801. During its rotation, the second adjusting screw 804 drives the second connecting seat 809 to move vertically downwards. As the second connecting seat 809 moves downwards, it drives the sliding block 810 to slide within the guide frame 808, causing the guide frame 808 to bring the other end of the limiting plate 807 into contact with the ground according to the angle of the ground. After the limiting plate 807 contacts the ground, the multiple limiting protrusions 15 on the bottom surface increase the friction between the limiting plate and the ground, restricting the movement of the wheel 802 from multiple directions, effectively preventing the wheel from deviating due to uneven force during the hoisting process, and providing stable support for the hoisting operation.

[0036] After limiting the crane's position, activate hook assembly 2 to move it along the crossbeam directly above the cargo to be lifted. Then, accurately hook the hook assembly onto the cargo's lifting point. Operate the crane's lifting control device to slowly raise hook assembly 2, allowing the cargo to smoothly leave the ground. Once the cargo has reached a safe height, activate hook assembly 2 again to lift the cargo to the target location. Slowly lower hook assembly 2 to gently place the cargo at the designated location, completing the lifting operation.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
