Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, specifically to a crane correction end beam. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is widely used in many fields today. The crane trolley moves on the end beam to move materials. However, due to factors such as unbalanced force or long-term wear, the crane trolley may tip over. Therefore, it is necessary to add corresponding anti-tipping structures to the crane trolley to avoid safety accidents.

[0003] The following are some of the core problems with the end beams of existing cranes during operation: First, after long-term use, factors such as wheel wear and track installation errors may cause the trolley to sway left and right or move in a serpentine manner during operation, which can easily cause the end beam to overturn; Second, during lifting operations, if the lifted load is severely tilted, the drive on both sides of the trolley is not synchronized, causing "rail biting", or if an unexpected impact occurs, the traditional trolley that only relies on the traveling wheels to run on the track is at risk of overturning. Once overturned, it will cause serious damage to the equipment and may even cause a major safety accident. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a correction end beam for cranes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A crane alignment end beam includes a load-bearing beam, an end beam trolley mounted on top of the load-bearing beam, and alignment and anti-tipping assemblies with identical structures installed at both ends of the end beam trolley. The alignment and anti-tipping assemblies include anti-tipping plates fixedly installed at the front and rear ends of the end beam trolley by bolts, angle steel support seats fixedly installed with the anti-tipping plates and the end beam trolley by bolts, and alignment wheels installed on the anti-tipping plates and cooperating with the load-bearing beam.

[0006] Preferably, a rectangular groove for mounting a load-bearing beam is provided at the center of the lower end of the anti-tipping plate, and a track groove is provided at the top of the rectangular groove that is recessed inward.

[0007] Furthermore, an anti-tipping support is integrally formed on the inner side of the lower end of the rectangular groove.

[0008] Preferably, there are two sets of correction wheels, which are symmetrically installed on both sides of the lower end of the anti-tipping plate.

[0009] Preferably, the load-bearing beam includes a load-bearing beam body welded together from two long steel plates with a spacer plate, a cover plate welded above and below the load-bearing beam body and extending outward on both sides, and an end beam trolley track welded to the surface of the cover plate above the load-bearing beam body.

[0010] The beneficial effects of this utility model are as follows: by assembling the anti-tipping plate and the correction wheel in the anti-tipping and correction assembly with the load-bearing beam, it can effectively prevent the end beam trolley from tipping over during operation, ensuring the stability of the crane. At the same time, the correction wheel can help the end beam trolley maintain the correct track during operation, prevent deviation, and improve operational safety. Attached Figure Description

[0011] Figure 1 This is a structural diagram of a crane correction beam according to the present invention; Figure 2 for Figure 1 Structural diagram of the anti-tipping plate assembly with the correction wheel. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0013] Example like Figure 1-2 As shown, a crane straightening end beam includes a load-bearing beam 1, an end beam trolley 2 mounted on the load-bearing beam 1, and straightening and anti-tipping components 3 with identical structures installed at both ends of the end beam trolley 2.

[0014] The load-bearing beam 1 includes a load-bearing beam body 11 welded from two long steel plates with a partition plate, a cover plate 12 welded above and below the load-bearing beam body 11 and extending outward on both sides, and an end beam trolley track 13 welded to the surface of the cover plate 12 above the load-bearing beam body 11.

[0015] Specifically, the structural design of the load-bearing beam 1 uses a combination of long steel plates and spacers, and is supported by the cover plate 12 and the end beam trolley track 13, which makes the load-bearing capacity of the load-bearing beam 1 stronger, and can better distribute the load during the operation of the crane, thereby improving the overall work efficiency.

[0016] The anti-tipping and correction assembly 3 includes an anti-tipping plate 31 that is fixedly installed at the front and rear ends of the end beam trolley 2 by bolts, an angle steel support 32 that is fixedly installed with the anti-tipping plate 31 and the end beam trolley 2 by bolts, and a correction wheel 33 that is installed on the anti-tipping plate 31 and cooperates with the load-bearing beam 1.

[0017] It should be further explained that by assembling the anti-tipping plate 31 and the straightening wheel 33 in the anti-tipping and anti-overturning assembly 3 in conjunction with the load-bearing beam 1, the end beam trolley 2 can be effectively prevented from overturning during operation, ensuring the stability of the crane. At the same time, the design of the straightening wheel 33 can help the end beam trolley 2 maintain the correct track during operation, prevent deviation, and improve operational safety. The lower center of the anti-tipping plate 31 has a rectangular groove 311 for mounting the load-bearing beam 1, and the top of the rectangular groove 311 is recessed to form a track groove 312. Specifically, the anti-tipping plate 31 spans the load-bearing beam 1 through the rectangular groove 311, while the track groove 312 spans the end beam trolley track 13. This ensures that the anti-tipping plate 31 does not contact the load-bearing beam 1 during the movement of the end beam trolley 2, thereby avoiding unnecessary wear, noise, and running resistance, and ensuring smooth trolley operation.

[0018] An anti-tipping support 313 is integrally formed on the inner side of the lower end of the rectangular groove 311. When a tipping tendency occurs, the anti-tipping support 313 will immediately abut against the side of the load-bearing beam, providing rigid mechanical support to prevent the tipping angle from expanding further.

[0019] Therefore, the rectangular groove 311 on the anti-tipping plate 31, together with the correction wheel 33, can provide the first layer of correction protection, and the anti-tipping support part 313 on the anti-tipping plate 31 can provide the second layer of anti-tipping protection.

[0020] Two sets of correction wheels 33 are symmetrically installed on both sides of the lower end of the anti-tipping plate 31. The two sets of correction wheels 33, installed symmetrically, roll directly on the two sides of the cover plate of the load-bearing beam 1, forming an effective guiding constraint. This can promptly correct the lateral deviation of the end beam trolley 2 during operation, avoiding severe friction between the wheel flange and the track, and track wear caused by deviation. This greatly reduces the wear of the wheels and tracks, extends the service life of the equipment, and at the same time, the smooth and unobstructed operation also reduces the load on the drive motor.

[0021] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
