Description

Technical Field

[0001] The invention mainly relates to the technical field of electric power construction auxiliary equipment, in particular to a cable pay-off rack. Background Art

[0002] The cable pay-off rack is a commonly used auxiliary equipment in power construction. Its main function is to install a large cable reel to facilitate the rotation of the cable reel to reel in and release the cable. Since the large cable reel is heavy, the current cable pay-off rack is generally made of a heavier metal structure. In addition to carrying the pay-off rack, it can also prevent rollover.

[0003] The existing cable pay-off rack still has the following defects:

[0004] ① The external structure of the pay-off rack is irregular, which makes storage and transportation inconvenient;

[0005] ② The pay-off rack cannot adjust and control the outgoing wire speed well. Since the driving and reduction mechanisms are mostly driven by a rotating shaft passing through the cable reel, the torque required for starting and adjusting is extremely large, and the adjustment effect is not good;

[0006] ③ The upper limit of the support capacity of the pay-off stand installed by passing a single axis through the cable reel is low, and the support stability needs to be improved. Summary of the invention

[0007] In order to address the deficiencies in the prior art, the present invention provides a cable pay-off stand, which has a higher upper limit of load-bearing capacity and can stably support and effectively control the pay-off and reeling of a large cable reel to better meet construction needs; after the pay-off stand is folded, the external structure is regular, which can improve space utilization and facilitate storage and transportation.

[0008] In order to achieve the above object, the present invention is implemented through the following technical solutions:

The cutting edge on one side of the lower connecting rod 42 is used to prevent the placement surface from being scratched and damaged when the cable pay-off racks are loaded and moved close to each other.

[0029] The protection assembly 7 includes an upper swing arm 71, which is rotatably mounted on the top of the triangular frame 1, and the upper swing arm 71 is rotatably connected to the lower swing arm 72. A protection rod 73 is installed between the two groups of the upper swing arms 71 and the lower swing arms 72, and the protection rod 73 is installed at the rotation connection between the upper swing arm 71 and the lower swing arm 72.

[0030] The tensioning drive device 8 includes a motor mounting seat 81, and the motor mounting seat 81 is fixedly mounted on the triangular frame 1. A tensioning drive motor 82 is fixedly mounted on the motor mounting seat 81. A wire rope drum 83 is rotatably mounted between the tensioning drive motor 82, the motor mounting seat 81 and the sub-frame 6. The output shaft of the tensioning drive motor 82 is connected to the rotating shaft of the wire rope drum 83. A wire rope 84 is wound around the wire rope drum 83. A guide ring 85 is also fixedly mounted on the sub-frame 6 on this side. When in use, the wire rope 84 passes through the guide ring 85. A column 86 is fixedly mounted in the sub-frame 6 on the side away from the tensioning drive device 8. When in use, the wire rope 84 of one cable pay-off rack is connected to the column 86 of another cable pay-off rack. The motor mounting seat 81 is respectively fixedly connected to the bottom side beam 11, the support rod 3, and the reinforcing rod 20; the tensioning drive motor 82 has a reducer structure, and the rotation of the tensioning drive motor 82 can drive the wire rope drum 83 to rotate and then tighten the wire rope 84 to make the two cable pay-off frames approach each other to set up the cable reel.

[0031] The motor mounting seat 2 91 of the rotating shaft driving device 9 is fixedly connected to the sub-frame 6. The motor mounting seat 2 91 is fixedly mounted with a rotating shaft driving motor 92 through a connecting column. A driving pulley 93 is mounted on the output shaft of the rotating shaft driving motor 92. A driven pulley 94 is mounted on one end of the supporting rotating shaft 5 close to the rotating shaft driving device 9. A transmission belt 95 is mounted on the driving pulley 93 and the driven pulley 94. The rotation of the rotating shaft driving motor 92 can drive the supporting rotating shaft 5 to rotate through the driving pulley 93, the transmission belt 95, and the driven pulley 94, thereby driving the cable reel to rotate.

[0032] The device is also provided with a control device, which is a control device based on a single-chip microprocessor. The control device is connected to a power supply and a tensioning drive motor 82 and a rotating shaft drive motor 92 in the device through a wired connection. The operator controls the operation of the device through the control device.

[0033] When the device is in use, two cable pay-off racks are placed on both sides of the cable reel to be paid out, the upper swing arm 71 in the protection component 7 is flipped upward, and the fixed plug 74 is inserted into the fixing hole 130 located at the upper part; a certain length of steel wire rope 84 is released by the control device, and the end of the steel wire rope 84 is connected to the column 86 of another set of cable pay-off racks; the positions of the two sets of cable pay-off racks are adjusted so that the cable reels are close to the triangular frames 1 on both sides of each cable pay-off rack, and the pre-tensioning operation is started by the control device, and the tensioning drive motor 82 drives the steel wire rope drum 83 to rotate and continuously tighten the steel wire rope 84 until the support shaft 5 contacts the cable reel and generates a large resistance and stops. After the cable pay-off racks on both sides are pre-tensioned, check again whether the relative position with the cable reel needs to be adjusted. After confirming the position, the device is started by control to set up the cable reel operation, and the tensioning drive motor 82 further rotates at a high power to tighten the steel wire rope 84. The two support shafts 5 set up the cable reel in the process of constantly approaching each other, and stop after being set up to a suitable height. After the cable reel is installed, the wire-releasing operation is started through the control device. The shaft drive motor 92 rotates to drive the support shaft 5 to rotate, thereby driving the cable reel to rotate and release the wire. The wire-releasing cable is led out from the outlet guide frame 10, and the wire-releasing work is started. The wire-releasing speed can be adjusted according to construction needs through the control device. Through the supporting effect of the supporting shafts 5 on both sides of the present scheme, the upper limit of the bearing capacity and the support stability of the cable pay-off rack can be effectively improved. At the same time, since the driving contact point is located outside the cable reel, the required driving torque is small, which can significantly improve the ability to adjust the speed of the incoming and outgoing wires. After the use of this device is completed, the protective component 7 is restored to the storage state, and the upper swing arm 71 and the lower swing arm 72 are flipped downward to fit flush with the inclined support beam 13, and the two pay-off racks are stacked up. Figure 5 The state shown can improve space utilization and facilitate storage and transportation.
