Description

Technical Field

[0001] This utility model relates to the field of mechanical auxiliary equipment technology, and more specifically to a belt pulley turning device. Background Technology

[0002] Belt pulleys are commonly used in mechanical transmission systems, such as material handling and mechanical transmission. To ensure the normal operation and maintenance of equipment, it is often necessary to manually rotate the belt pulleys to check the operating status of the equipment, troubleshoot problems, or prepare for equipment startup.

[0003] In the traditional manual turning process, the operator usually turns the pulley directly by hand to make the pulley rotate to the appropriate position. This method is time-consuming and laborious. The existing manual turning device has a complex structure and is cumbersome to operate, which is not convenient for the operator to turn the pulley quickly and easily. At the same time, it occupies a lot of space, especially when the equipment installation space is limited or the operating environment is harsh, making the operation more difficult. In addition, it cannot be stored away.

[0004] Therefore, how to provide a pulley cart device that is simple in structure, easy to operate, and saves space is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a pulley turning device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pulley turning device for connection with a pulley drive includes:

[0008] A snap-fit ​​component, which is fixed to the pulley shaft of the pulley and arranged along the axial direction of the pulley shaft;

[0009] A drive rod, one end of which is snapped onto the outside of the pulley shaft, and a locking groove is provided on the side wall of the end of the drive rod away from the snap-fit ​​part;

[0010] The handle is cranked, and the crank is hinged to the end of the drive rod away from the latching member via a hinge, and can be folded and stored in the locking groove.

[0011] Through the above technical solution, the pulley turning device provided by this utility model efficiently converts external force into rotational power through the cooperation of the drive rod and the locking member. The operator only needs to apply a small force to easily drive the locking member and the pulley shaft to rotate circumferentially, without the need to directly manually rotate the pulley, reducing the operator's labor intensity and enabling precise rotation to the appropriate position. It eliminates the need for cumbersome tool installation and debugging steps, greatly simplifying the turning operation process, saving operation time, and improving work efficiency. The crank handle can be easily unfolded and retracted through the hinge, allowing the operator to quickly unfold the crank handle for turning operations when needed and quickly retract it after operation, greatly improving the convenience and efficiency of operation. This significantly reduces the overall size of the device, saving space. This compact design is particularly suitable for equipment installation environments with limited space, solving the technical problem of complex structure and large space occupation in existing turning devices.

[0012] Preferably, in the above-mentioned pulley turning device, the hinge includes a pin and a torsion spring. The pin passes through the drive rod and the crank handle, and the torsion spring is sleeved on the outside of the pin, with its two ends abutting against the inner sides of the drive rod and the crank handle, respectively. The torsion spring provides elastic restoring force, ensuring that the handle automatically maintains an angle (90°-120° adjustable) with the drive rod when unfolded, resulting in strong operational stability. When folded, the torsion spring assists the handle in returning to the locking groove, improving storage efficiency.

[0013] Preferably, in the above-mentioned pulley turning device, the depth of the locking groove is greater than the diameter of the crank handle, and the outer surface of the crank handle is in contact with the groove wall of the locking groove. The depth design prevents the handle from being exposed after being stored, preventing bumps or accidental activation; the groove wall contact reduces handle shaking and ensures the compactness of the structure after storage.

[0014] Preferably, in the above-mentioned pulley turning device, a first magnetic block is fixed in the locking groove, and the crank handle has a first magnetic piece magnetically connected to the first magnetic block. The magnetic force secures the retracted handle, preventing it from dislodging from the locking groove due to vibration or external force, thus enhancing safety. No additional locking structure is required. Simultaneously, the magnetic force is greater than the spring force of the torsion spring, ensuring the crank handle is stably retracted in the locking groove. When needed, external force overcomes the magnetic force, allowing the crank handle to disengage from the locking groove and unfold.

[0015] Preferably, in the above-mentioned pulley turning device, the cross-section of the locking member is a polygonal rod structure, and the locking end of the drive rod is provided with a polygonal limiting hole that matches the locking member. The polygonal structure design can effectively prevent relative rotation between the drive rod and the locking member, ensuring stable power transmission and accurate torque transmission.

[0016] Preferably, in the above-mentioned pulley turning device, a second magnetic block is fixed inside the polygonal limiting hole, and a second magnetic piece corresponding to the second magnetic block is fixed to the end face of the snap-fit ​​component. Magnetic attraction assists in quick alignment of the snap-fit ​​component and the drive rod, simplifying the installation steps; it enhances the connection stability between the drive rod and the snap-fit ​​component, preventing accidental separation; and when disassembly is required, the drive rod can be axially disassembled by overcoming the magnetic attraction force.

[0017] Preferably, in the above-mentioned pulley turning device, the outer side of the crank handle is covered with an anti-slip rubber layer. This increases the handle's friction, prevents hand slippage, and improves operational safety; the rubber layer also buffers vibrations and reduces operator fatigue.

[0018] Preferably, the above-mentioned pulley turning device further includes a protective cover covering the outside of the pulley. The protective cover has a clearance hole, and the end of the snap-fit ​​member away from the pulley shaft extends through the clearance hole to the outside of the protective cover. The protective cover isolates the pulley from the influence of external factors such as dust and oil, extending the life of the device; the end of the snap-fit ​​member extending to the outside of the protective cover allows the turning operation to be performed without removing the protective cover.

[0019] Preferably, in the above-mentioned pulley turning device, the outer wall of the protective cover is fixed with a buckle for engaging the drive rod. The buckle design allows the drive rod to be fixed to the protective cover after storage, further saving space, and allowing it to be picked up and used at any time, optimizing the overall layout of the device and improving portability and neatness.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a belt pulley turning device, which has the following beneficial effects:

[0021] 1. This utility model allows the operator to easily drive the pulley to rotate simply by shaking the handle, without the need for complicated tool installation and debugging, greatly simplifying the turning operation process; the handle can be folded and stored through the hinge, which can be quickly unfolded for turning operation when needed, and can be quickly stored in the locking slot after the operation is completed, reducing the space occupied by the device, and is especially suitable for narrow or complex working environments.

[0022] 2. This utility model improves safety performance by setting up a protective cover. At the same time, the end of the snap-fit ​​component away from the pulley shaft extends to the outside of the protective cover, so the operation can be completed without removing the protective cover when turning the gear.
