Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane technology, and in particular to a disc brake for a bridge crane. Background Technology
[0002] The disc brake of the bridge crane plays a significant role. During operation, it can precisely control the lifting and running speed, ensuring that the load is lifted and moved smoothly according to instructions, and guaranteeing operational accuracy. When not in operation, it can brake tightly to prevent the load from slipping, providing reliable safety protection for the work site and effectively avoiding accidents.
[0003] However, due to structural design limitations, existing disc brakes for bridge cranes cannot simultaneously brake the sides and bottom of the equipment when braking, resulting in an incomplete and unbalanced braking process. This not only prolongs the braking distance and reduces work efficiency, but may also fail to stop the equipment in a timely and stable manner in emergency situations, greatly threatening the operational safety of bridge cranes.
[0004] Therefore, this application provides a disc brake for a bridge crane to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disc brake for bridge cranes.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a disc brake for a bridge crane, comprising:
[0007] Support base;
[0008] A clamping assembly is placed on top of a support base. The clamping assembly includes a protective shell fixed to the top of the support base. A rotating shaft is rotatably connected to the top of the support base away from the protective shell. A support plate is fixed to the top of the rotating shaft. A damping spring is provided on one side of the support plate. A clamping block is fixed to the other end of the damping spring. An anti-slip plate is fixed to the other end of the clamping block.
[0009] A braking assembly is located on the top of a support base away from the clamping assembly. The braking assembly includes a support arc plate fixed to the top of the support base. A fixed housing is fixed to the other side of the support arc plate. A sliding plate is slidably connected to the bottom of the fixed housing. A connecting plate is fixed to the outside of the sliding plate. A second telescopic rod is provided on the connecting plate. The other end of the second telescopic rod is connected to the fixed housing.
[0010] Furthermore, a top fixing cover is fixed to the top of the protective shell, a driving power supply is fixed to one side of the top fixing cover, a first telescopic rod is provided on one side of the driving power supply, and a push plate is provided on the other side of the first telescopic rod.
[0011] The beneficial effects of adopting the above-mentioned further solution are: the top fixed cover on the top of the protective shell provides protection and installation base for the internal materials, and the drive power supply is fixed on it. When started, the drive power supply drives the first telescopic rod on one side to extend and retract, thereby pushing the push plate to move. This component combination can make precise position adjustments to the internal structure, thereby achieving effective control of the braking components.
[0012] Furthermore, the top of the top fixing cover has a slot, and the top of the support plate is disposed within the slot.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the top fixing cover accommodates the top of the support plate through the slot, which plays a role in stabilizing support and limiting position.
[0014] Furthermore, a piston is provided on the connecting plate, and brake pads are fixed inside both the piston and the fixed housing.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the piston on the connecting plate cooperates with the brake pad inside the fixed housing. When braking, the piston pushes the brake pad to press against the brake disc, and the braking is achieved by using friction, ensuring that the equipment stops safely.
[0016] Furthermore, a connecting wire is provided on one side of the drive power supply, and the other end of the connecting wire is fixedly connected to the piston.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the piston is driven, and with the help of the force transmitted by the connecting line, it synchronously drives the motor on one side to operate, thereby driving the first telescopic rod to work. The coordinated action of multiple components achieves an efficient and synchronous braking effect.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] 1. The protective outer shell is fixed on the support base to protect the internal components. The rotating shaft is rotatably connected to the support base, and the support plate on top of it serves as a support structure. One end of the damping spring is connected to the support plate, which can provide buffering and rebound force. When braking is required, the damping spring contracts, which drives the clamping block and its anti-slip plate to move towards the braking component. The friction generated by the close contact between the anti-slip plate and the braking component causes the braking component to stop rotating, thereby achieving an efficient and stable braking effect and ensuring the safe operation of the bridge crane.
[0020] 2. The support arc plate is fixed on the support base, providing a stable support structure for the entire braking assembly. The fixed housing on its side is used to protect the internal components. The sliding plate at the bottom can slide flexibly within the fixed housing. The sliding plate is pushed or pulled by the extension and retraction movement of the second telescopic rod on the outer connecting plate. When braking is required, the second telescopic rod extends, causing the sliding plate, piston, and inner brake pads to come into close contact with the brake disc, generating friction and thus achieving an effective braking effect, ensuring that the crane stops running safely and smoothly.

[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] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a disc brake for a bridge crane, comprising: a support base 1;
[0032] The clamping assembly 2 is placed on top of the support base 1. The clamping assembly 2 includes a protective shell 29 fixed to the top of the support base 1. A rotating shaft 21 is rotatably connected to the top of the support base 1 away from the protective shell 29. A support plate 22 is fixed to the top of the rotating shaft 21. A damping spring 24 is provided on one side of the support plate 22. A clamping block 23 is fixed to the other end of the damping spring 24. An anti-slip plate 26 is fixed to the other end of the clamping block 23. The protective shell 29 is fixed to the support base 1 to provide protection for the internal components. The rotating shaft 21 is rotatably connected to the support base 1. The support plate 22 on its top serves as a support structure. One end of the damping spring 24 is connected to the support plate 22 and can provide buffering and rebound force. When braking is required, the damping spring 24 contracts, driving the clamping block 23 and the anti-slip plate 26 on it to move towards the braking component. The friction generated by the tight contact between the anti-slip plate 26 and the braking component stops the rotation of the braking component, thereby achieving an efficient and stable braking effect and ensuring the safe operation of the bridge crane.
[0033] Braking assembly 3 is located on the top of the support base 1 away from the clamping assembly 2. Braking assembly 3 includes a support arc plate 31 fixed to the top of the support base 1. A fixed housing 32 is fixed to the other side of the support arc plate 31. A sliding plate 33 is slidably connected to the bottom of the fixed housing 32. A connecting plate 34 is fixed to the outside of the sliding plate 33. A second telescopic rod 36 is provided on the connecting plate 34. The other end of the second telescopic rod 36 is connected to the fixed housing 32. The support arc plate 31 is fixed to the support base 1, providing a stable support structure for the entire braking assembly 3. The fixed housing 32 on its side is used to protect the internal components. The sliding plate 33 at the bottom can slide flexibly within the fixed housing 32. The second telescopic rod 36 on the outer connecting plate 34 moves to push or pull the sliding plate 33. When braking is required, the second telescopic rod 36 extends, causing the sliding plate 33, piston 35, and inner brake pad 37 to come into close contact with the brake disc, generating friction, thereby achieving an effective braking effect and ensuring that the crane stops running safely and smoothly.
[0034] Furthermore, such as Figure 1 - Figure 3As shown: A top fixing cover 210 is fixed to the top of the protective housing 29. A drive power supply 28 is fixed to one side of the top fixing cover 210. A first telescopic rod 25 is provided on one side of the drive power supply 28. A push plate 27 is provided on the other side of the first telescopic rod 25. The top fixing cover 210 on the top of the protective housing 29 provides protection and a mounting base for the internal materials. The drive power supply 28 is fixed on it. When started, the drive power supply 28 drives the first telescopic rod 25 on one side to extend and retract, thereby pushing the push plate 27 to move. This component combination can make precise position adjustments to the internal structure, thereby achieving effective control of the braking components.
[0035] The above solutions still have braking stability issues, such as... Figure 1 - Figure 4 As shown: In this scheme, a piston 35 is provided on the connecting plate 34. Both the piston 35 and the inside of the fixed housing 32 are fixed with brake pads 37. The piston 35 on the connecting plate 34 and the brake pads 37 inside the fixed housing 32 cooperate with each other. When braking, the piston 35 pushes the brake pads 37 to press against the brake disc, and the braking is achieved by friction, so as to ensure the safe stop of the equipment.
[0036] The above solutions also have the problem of simultaneous braking, such as... Figure 1 - Figure 3 As shown: In this scheme, a connecting line 4 is provided on one side of the drive power supply 28, and the other end of the connecting line 4 is fixedly connected to the piston 35. The piston 35 is driven, and with the force transmitted by the connecting line 4, it synchronously drives the motor on one side to run, thereby driving the first telescopic rod 25 to work. The coordinated action of multiple components achieves an efficient and synchronous braking effect.
[0037] Working principle: such as Figure 1 - Figure 4 As shown, the protective shell 29 is fixed on the support base 1 to provide protection for the internal components. The rotating shaft 21 is rotatably connected to the support base 1, and the support plate 22 on its top serves as a support structure. One end of the damping spring 24 is connected to the support plate 22, which can provide buffering and rebound force. When braking, the damping spring 24 contracts, driving the clamping block 23 and the anti-slip plate 26 to move towards the braking component. The friction generated by the contact between the anti-slip plate 26 and the braking component stops the braking component from rotating, thus achieving the braking effect.
[0038] The supporting arc plate 31 is fixed on the supporting base 1 to provide stable support for the braking assembly 3. The fixed housing 32 on its side protects the internal components. The sliding plate 33 at the bottom can slide inside the fixed housing 32. The second telescopic rod 36 on the outer connecting plate 34 can extend and retract, which can push or pull the sliding plate 33. When braking, the second telescopic rod 36 extends, which drives the sliding plate 33, piston 35 and inner brake pad 37 to come into close contact with the brake disc, generating friction to achieve braking.
[0039] The top fixing cover 210 on the top of the protective shell 29 provides protection and installation base for the internal materials. The drive power supply 28 is fixed on it. When started, the drive power supply 28 drives the first telescopic rod 25 to extend and retract, pushing the push plate 27 to move, thereby realizing effective control of the braking components. The top fixing cover 210 accommodates the top of the support plate 22 through the slot, which plays a role in stabilizing support and limiting.
[0040] The piston 35 on the connecting plate 34 cooperates with the brake pad 37 inside the fixed housing 32. When braking, the piston 35 pushes the brake pad 37 to press against the brake disc, and braking is achieved by friction. When the piston 35 is driven, it drives the drive power supply 28 on one side to operate synchronously with the force transmitted by the connecting line 4, thereby driving the first telescopic rod 25 to work. Multiple components work together to achieve an efficient and synchronous braking effect, ensuring the safe operation of the bridge crane.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
