Description

Technical Field

[0001] The invention relates to a double hydraulic drive distribution network construction cable retracting and releasing reel, and relates to the technical field of distribution network construction cable retracting and releasing. Background Art

[0002] In the mechanized operation process of distribution network construction, the cable is generally retracted and released by electric drive or manual winding. However, it is difficult to obtain electricity during outdoor operations, and electric drive often requires a very long cable to ensure its working range. Obviously, it is labor-intensive and inconvenient to wind such a long and heavy cable manually, and the work efficiency is also very low. Therefore, the use of hydraulic method to drive the reel to retract the cable can effectively increase the cable retraction length and reduce labor intensity, thereby improving the efficiency of cable retraction. The existing cable reel drive scheme is as follows: a motor is used to drive a reducer, the reducer drives a small sprocket, the small sprocket drives a large sprocket through a chain, and the large sprocket is fixed to the drum by bolts to drive the drum to rotate. The biggest problem with the prior art is that a motor is used to drive a reducer to obtain a larger output torque, which leads to the following disadvantages of the cable reel in actual applications:

[0003] 1. The drive system is very complex, with too many components, low reliability and high cost. 2. In actual applications, it occupies a large volume and is difficult to use in situations where the vehicle size is limited. 3. The system speed has no speed limit and self-locking function. In actual use, the speed of the cable reel is difficult to control, and the reel rotates randomly, which makes it easy for the cable to be entangled and scattered. Summary of the invention

[0004] The invention provides a double hydraulic drive distribution network construction cable retracting and unreeling reel for overcoming the defects of the prior art cable retracting and unreeling reel system being complex, having low reliability, occupying a large space and having difficulty in controlling the rotation speed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The invention discloses a double hydraulically driven cable retractable reel for distribution network construction, comprising a reel mounting frame, both ends of which are provided with a cable reel body, an upper portion of which is provided with a mechanical transmission mechanism for driving the cable reel body, and a lower portion thereof is provided with a hydraulic motor, and the mechanical transmission mechanism is a sprocket chain transmission mechanism.

[0007] Furthermore, a support plate for supporting the hydraulic motor is provided below the reel mounting frame.

[0008] Furthermore, the mechanical transmission mechanism includes a small sprocket located on the side of the reel mounting frame, the small sprocket is connected to the output end of the hydraulic motor, and a large sprocket is located on the cable reel body, and the two transmit power through a chain. A bearing seat is provided above the reel mounting frame, and the transmission shaft passes through the two bearing seats, and one end of the transmission shaft is connected to the large sprocket.

[0009] Furthermore, the cable reel body includes a supporting sleeve, and the two ends of the supporting sleeve are respectively connected to a reel inner plate and a reel outer plate, a plurality of reinforcing ribs are welded between the reel inner plate and the reel outer plate, and a reel outer plate traction groove is provided on the reel outer plate.

[0010] Furthermore, the two bearing seats are fixedly connected to the reel mounting frame by bolts to provide support for the transmission shaft and the cable reel body.

[0011] Furthermore, the bottom of the reel mounting frame is fixed to the vehicle body by bolts so as to move with the vehicle.

[0012] The beneficial effects achieved by the present invention are: it adopts a hydraulic drive method, occupies a small space, but the output torque is greatly increased, and the cable can be retracted and released over a longer distance. The entire system does not require a deceleration device, has fewer components, and has high reliability. The entire reel is fixed inside the vehicle body through a mounting frame, has high maneuverability, and can adapt to a variety of outdoor working environments. BRIEF DESCRIPTION OF THE DRAWINGS
