Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, specifically to a trolley movement anti-tipping mechanism. 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 core problems with existing crane trolleys (especially end beam trolleys) during operation: First, during lifting operations, if the lifted load is severely tilted, the drive on both sides of the trolley is asynchronous leading to "rail wear," or an unexpected impact occurs, the traditional trolley, which relies solely on its traveling wheels to run on the rails, is at risk of tipping over. Once tipped over, it can cause serious damage to the equipment and even lead to a major safety accident. Second, after long-term use, factors such as wheel wear and rail installation errors may cause the trolley to sway left and right or move in a serpentine pattern (i.e., "deviation") during operation. This not only affects positioning accuracy but also accelerates the wear of the wheels and rails, generating noise and vibration. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a trolley-moving anti-tipping mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A trolley-mounted anti-tipping mechanism includes a load-bearing beam, an end beam trolley mounted on top of the load-bearing beam, and a first anti-tipping assembly and a second anti-tipping assembly with identical structures mounted at both ends of one side of the end beam trolley. The first anti-tipping assembly includes an anti-tipping bracket, a first side anti-tipping wheel and a second side anti-tipping wheel mounted on both sides of the middle of the anti-tipping bracket and cooperating with the load-bearing beam, and a lower anti-tipping wheel mounted at the lower end of the anti-tipping bracket and cooperating with the load-bearing beam.

[0006] Preferably, the anti-tipping bracket includes a bracket body, an installation part that bends 90° from the upper end of the bracket body to one side and is fixed to the end beam trolley by bolts, an anti-tipping support part integrally formed on the inner side of the middle of the bracket body and close to the side of the load-bearing beam, and a bending part that bends 90° from the lower end of the bracket body to one side for fixing and installing the lower anti-tipping wheel.

[0007] Furthermore, the anti-tipping support maintains a certain gap with the side of the load-bearing beam.

[0008] Preferably, the first anti-rollover wheel and the second anti-rollover wheel are arranged on the same straight line.

[0009] Preferably, the load-bearing beam includes a load-bearing beam body welded 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, an end beam trolley track welded to the surface of the cover plate above the load-bearing beam body, and an anti-tipping wheel guide rail fixed to the side of the load-bearing beam body by bolts.

[0010] Furthermore, the anti-tipping wheel guide rail cooperates with the first side anti-tipping wheel, the second side anti-tipping wheel and the lower anti-tipping wheel to jointly restrict the tipping of the end beam trolley.

[0011] Preferably, end panels are welded to both ends of the end beam trolley, and the lower end of the end panel is provided with a correction groove.

[0012] Preferably, the first anti-rollover component and the second anti-rollover component have symmetrical structures.

[0013] The beneficial effects of this utility model are as follows: 1. By cooperating with the anti-tipping wheel guide rail at three points—the first anti-tipping wheel, the second anti-tipping wheel, and the lower anti-tipping wheel—the end beam trolley is "held" onto the load-bearing beam from three directions: the side and the bottom. Even in extreme situations such as wheel derailment or asynchronous drive causing the trolley to tilt, the gap reserved between the anti-tipping support and the side of the load-bearing beam will be converted into mechanical support, directly abutting against the load-bearing beam, forming the last solid physical defense line, effectively preventing the trolley from completely tipping over, and greatly improving the safety of equipment operation. 2. The correction groove works in conjunction with the end beam trolley track, acting as a guide device to effectively limit the trolley's left and right swaying during movement, ensuring its smooth operation along a straight line. The symmetrically arranged first and second anti-tipping components work together to balance the constraint forces, avoiding jamming or instability that may be caused by unilateral force, further enhancing the stability of operation.

[0015] 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.

[0016] Example like Figure 1-4 As shown, a trolley-moving anti-tipping mechanism includes a load-bearing beam 1, an end beam trolley 2 mounted on the load-bearing beam 1, and a first anti-tipping component 3 and a second anti-tipping component 4 with identical structures installed at both ends of one side of the end beam trolley 2.

[0017] The load-bearing beam 1 includes a load-bearing beam body 11 welded from two long steel plates with a spacer plate, a cover plate 12 welded above and below the load-bearing beam body 11 and extending outward on both sides, an end beam trolley track 13 welded to the surface of the cover plate 12 above the load-bearing beam body 11, and an anti-tipping wheel guide rail 14 fixed to the side of the load-bearing beam body 11 by bolts.

[0018] End panels 21 are welded to both ends of the end beam trolley 2. A correction groove 211 is formed at the lower end of each end panel 21. The correction groove 211 cooperates with the end beam trolley track 13 to prevent left-right swaying and correct deviation during the movement of the end beam trolley 2. Specifically, the correction groove 211 constitutes an additional guiding mechanism that effectively suppresses possible left-right swaying of the end beam trolley 2 during movement, improving operational accuracy and stability. When the end beam trolley 2 deviates slightly, the correction groove contacts the track, generating a force that forces the trolley back to the correct position, achieving automatic correction and preventing accumulated deviation from causing rail wear or jamming.

[0019] The first anti-tipping component 3 includes an anti-tipping bracket 31, a first-side anti-tipping wheel 32 and a second-side anti-tipping wheel 34 installed on both sides of the middle of the anti-tipping bracket 31 and cooperating with the load-bearing beam 1, and a lower anti-tipping wheel 35 installed at the lower end of the anti-tipping bracket 31 and cooperating with the load-bearing beam 1. Specifically, by setting the first-side anti-tipping wheel 32, the second-side anti-tipping wheel 34 and the lower anti-tipping wheel 35, the end beam trolley is constrained from three directions, forming a stable spatial anti-tipping structure. This fundamentally prevents the trolley from tilting and lifting laterally relative to the load-bearing beam. Moreover, the cooperation of the first anti-tipping component 3 and the second anti-tipping component 4 ensures that the trolley has two support points on that side when it moves to any position, with uniform force distribution and a stable and reliable anti-tipping effect.

[0020] The anti-tipping bracket 31 includes a bracket body 311, an installation part 312 that is bent 90° to one side from the upper end of the bracket body 311 and fixed to the end beam trolley 2 by bolts, an anti-tipping support part 313 integrally formed on the inner side of the middle of the bracket body 311 and close to the side of the load-bearing beam 1, and a bending part 314 that is bent 90° to one side from the lower end of the bracket body 311 for fixing and installing the lower anti-tipping wheel 35.

[0021] The anti-tipping support 313 maintains a certain gap with the side of the load-bearing beam 1 to provide mechanical support in case of tipping. Specifically, maintaining a certain gap ensures that the anti-tipping support will not rub against the load-bearing beam during normal operation of the equipment, thereby avoiding unnecessary wear, noise, and running resistance, and ensuring smooth operation of the trolley. When a tipping tendency occurs, this small gap will quickly disappear, and the anti-tipping support will immediately abut against the side of the load-bearing beam, providing rigid mechanical support to prevent the tipping angle from further increasing.

[0022] The first anti-tipping wheel 32 and the second anti-tipping wheel 34 are arranged on the same straight line. Specifically, this ensures that when the two side wheels contact the anti-tipping wheel guide rail, the force points are on the same horizontal line, avoiding additional torque caused by height misalignment, making the lateral restraint force more balanced and effective. The same straight line arrangement can make the end beam trolley 2 more stable in posture when subjected to lateral force, reducing the possibility of jamming or shaking.

[0023] In this embodiment, the anti-tipping wheel guide rail 14 cooperates with the first side anti-tipping wheel 32, the second side anti-tipping wheel 34 and the lower anti-tipping wheel 35 to jointly restrict the tipping of the end beam trolley 2.

[0024] In this embodiment, the first anti-rollover component 3 and the second anti-rollover component 4 are symmetrically structured and located at both ends of the same side of the end beam trolley 2. Specifically, the symmetrical arrangement of the first anti-rollover component 3 and the second anti-rollover component 4 ensures that the anti-rollover forces at both ends of the end beam trolley 2 are completely symmetrical, providing optimal balance.

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.
