Cable spring reel support bracket

Abstract

This utility model discloses a cable spring drum support frame, including a wheel mounting plate, stiffening plates, a frame, a wheel frame, pulleys, a U-shaped frame, and a spring drum. The wheel mounting plate is configured with an L-shaped structure, and two pulleys are arranged horizontally and longitudinally on the lower inner wall of the wheel frame, forming a cable passage area between the four pulleys. This cable spring drum support frame, by setting four pulleys arranged horizontally and longitudinally to form a cable passage area, ensures that the pulleys support the cable regardless of which cable is attached to it, preventing wear during unwinding. Furthermore, the pulleys consist of a screw, a sleeve, and a lock nut; the sleeve can be replaced individually after wear, offering the advantage of easy maintenance.

Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, and in particular relates to a cable spring drum support frame. Background Technology

[0002] A rail-crossing crane is a special lifting device suspended from rails or steel beams, characterized by modular design, multi-point support, and the ability to operate across rails. A cable spring reel is a cable winding device that provides power, control power, or control signals to large mobile equipment. Existing spring reels only provide vertical support to prevent wear during cable winding and unwinding; wear problems still occur when the cable is outside the pulley. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a spring drum support frame that forms a support area between four pulleys and provides comprehensive protection for the cable during winding.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a cable spring drum support frame, comprising a wheel mounting plate, a stiffening plate, a frame, a wheel frame, pulleys, a U-shaped frame, and a spring drum. The wheel mounting plate is configured as an L-shaped structure, and the U-shaped frame is screwed and fixedly installed at the rear end of the wheel mounting plate. The upper and lower ends of the stiffening plate are fixedly connected to the wheel mounting plate and the frame, respectively. The inner end of the spring drum is fixedly installed on the wheel mounting plate, and the wheel frame is fixedly installed on the frame. Two pulleys are arranged horizontally on the upper side of the inner wall of the rotating wheel frame, and two pulleys are arranged horizontally on the lower side of the inner wall of the rotating wheel frame. A cable passage area is formed between the four pulleys.

[0005] Preferably, the pulley consists of a screw, a sleeve, and a lock nut. The screw is slidably installed in the through hole of the wheel frame, the sleeve is slidably fitted onto the cylindrical section of the screw, and the lock nut is screwed onto the threaded section of the screw to lock and fix it to the wheel frame.

[0006] Preferably, both the top and bottom ends of the stiffener are rounded.

[0007] Preferably, the lower part of the frame is provided with two semi-circular plates, which are respectively screwed to the lower end of the stiffening plate and the wheel frame.

[0008] Preferably, the screws and lock nuts of the horizontally arranged pulleys lock and fix the wheel frame to the frame.

[0009] Preferably, the inner end of the spring drum is also fixedly connected to the stiffening plate.

[0010] Compared with the prior art, the advantages of this utility model are: This cable spring reel support frame forms a cable passage area by setting four pulleys arranged longitudinally and transversely. Regardless of which pulley the cable is attached to, the pulley can provide support for the cable, avoiding wear on the cable during unwinding. In addition, the pulley is composed of a screw, a sleeve, and a lock nut, and the sleeve can be replaced individually after wear, which has the advantage of easy maintenance.

[0016] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 4 The cable spring reel support frame shown includes a wheel mounting plate 1, a stiffener 2, a frame 3, a wheel rim 4, pulleys 41, a U-shaped frame 5, and a spring reel 7. The wheel mounting plate 1 is configured as an L-shaped structure. The U-shaped frame 5 is screwed and fixedly installed at the rear end of the wheel mounting plate 1. The upper and lower ends of the stiffener 2 are fixedly connected to the wheel mounting plate 1 and the frame 3, respectively. The inner end of the spring reel 7 is fixedly installed on the wheel mounting plate 1. The wheel rim 4 is fixedly installed on the frame 3. Two pulleys 41 are arranged horizontally on the upper side of the inner wall of the wheel rim 4, and two pulleys 41 are arranged horizontally on the lower side of the inner wall of the wheel rim 4. The four pulleys 41 form a cable passage area.

[0017] The pulley 41 consists of a screw 411, a sleeve 412, and a lock nut 413. The screw 411 is slidably installed in the through hole of the wheel frame 4. The sleeve 412 is slidably fitted onto the cylindrical section of the screw 411 and can rotate freely on the screw 411. The lock nut 413 is screwed onto the threaded section of the screw 411 and locks it to the wheel frame 4. After the sleeve 412 wears out, the lock nut 413 can be unscrewed, the screw 411 and the sleeve 412 can be pulled out, and the sleeve 412 can be replaced separately.

[0018] The top and bottom ends of the stiffening plate 2 are both rounded to reduce its weight.

[0019] The lower part of the frame 3 is provided with two semi-circular plates 31, which are screwed to the lower end of the stiffening plate 2 and the wheel frame 4 respectively to reduce the overall weight of the frame 3.

[0020] The screw 411 and lock nut 413 of the horizontally arranged pulleys 41 lock and fix the wheel frame 4 and the frame 3.

[0021] The inner end of the spring drum 7 is also fixedly connected to the stiffening plate 2. The stiffening plate 2 can also thicken the wheel mounting plate 1 and improve the firmness of the inner end of the spring drum 7.

[0022] The U-shaped frame 5 and the wheel mounting plate 1 are fitted together and installed on the column of the lifting equipment. The cable is wound on the spring drum 7. The cable passes through the cable passage area formed between the four pulleys 41. The cable passage area is located below the spring drum 7 to avoid the cable from getting stuck due to excessive offset angle with the spring drum 7 when unwinding.
