Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable laying machine for construction. Background Art

[0002] A cable is a device for transmitting electrical energy or signals. It is usually a rope-like cable made up of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. Auxiliary devices such as pay-off racks are generally used during the cable laying process.

[0003] For example, the Chinese patent with publication number CN208980033U proposes a cable pay-off bracket, which passes the cable drum through a connecting rod, and the two ends of the connecting rod are mounted on two brackets. By adjusting the length of the connecting rod, it can be suitable for the insertion of cable drums of different sizes, thereby realizing the positioning and pay-off of cable drums of different sizes. A plurality of support blocks are arranged at intervals on the movable frame of the bracket, and a rotating device is movably connected between the support blocks in the same position, so that the rotating device can be conveniently placed on support blocks of different heights to adapt to the pay-off height. The rotating device is provided with a roller to facilitate the rotation of the connecting rod in the arc groove of the rotating device, thereby improving the pay-off efficiency. However, in this scheme, when the staff pays off the cable, the staff will pull one end of the cable to pay off the cable. When the cable drum rotates, there is a certain inertia, and after paying off the cable, there will often be multiple runs of the cable, so the staff needs to use tools such as wooden sticks to limit the rotation speed. Since the inertia of the cable drum may be large when it rotates, it is often difficult to control the speed, which may cause excessive pay-off. Utility Model Content

The block 22 is movably connected with the card hole 19. Through the provided block 22, when the staff adjusts the height of the placement block 3, the staff pulls the adjustment plate 20, and then the inclined surface of the block 22 is squeezed with the inclined surface of the card hole 19, and then the second spring 23 is squeezed, and the block 22 enters the interior of the storage groove 21 along the direction of the guide column 24. When the staff moves the adjustment plate 20 to a suitable position, the second spring 23 rebounds and drives the block 22 to enter the interior of the card hole 19 again to limit the adjustment plate 20, thereby increasing the height of the support plate 2. When the staff needs to store the adjustment plate 20, the block 22 will be pushed along the guide column 24 into the interior of the storage groove 21. At this time, the staff pushes the adjustment plate 20 upward to enter the movable groove 1 7, so as to store the adjustment plate 20, which is convenient for adjusting the height of the support plate 2, and push plates 26 are fixedly installed on both sides of the block 22, and the push plates 26 are movably sleeved with the inside of the moving hole 18.

A plurality of rubber plates 35 are fixedly installed on the bottom surface of the base 32. When the staff places it on the cement ground, the rubber plates 35 will increase the friction between the ground and the support plate 2, which is convenient for limiting the support plate 2. A support block 29 is fixedly installed on one side of the limiting frame 9, and a limiting hole 30 is provided on the top surface of the support block 29.

The inner wall surface of the threaded hole 28 is threadedly connected with the outer wall surface of the threaded column 31. Through the provided support block 29, when the staff needs to replace the pay-off roller 1, they first rotate the threaded column 31 out of the inside of the load-bearing block 27, and then hold the support block 29 and lift it up, and then drive the limiting frame 9 to move upward. At this time, after turning the limiting frame 9 180 degrees, the staff takes the pay-off roller 1 out of the inside of the placement block 3, and then places the new pay-off roller 1 inside the placement block 3.After the staff member holds the support block 29 again and moves the limiting frame 9 back to the original position, the staff member again puts the threaded column 31 into the load-bearing block 27 of the limiting hole 30 and tightens it, which makes it easier to replace the pay-off roller 1.

[0025] Working principle: Please refer to Figure 1-Figure 5 As shown, through the arrangement of the pay-off roller 1, when the staff pays off the cable, firstly, after adjusting the positions of the two support plates 2 by the width of the pay-off roller 1, the staff then takes the limiting frame 9, rotates the limiting frame 9 to a certain angle, and then opens the interior of the placement block 3, and the staff places the pay-off roller 1 inside the support plate 2, and then pulls the limiting frame 9 again to rotate it, and then rotates the limiting frame 9 to its original position, and then the staff pulls the cable at this time, and then the pay-off roller 1 drives the pay-off roller 1 to rotate as the staff pulls the cable, and at the same time, the ball 6 contacting the surface of the pay-off roller 1 also follows The pay-off roller 1 rotates to reduce the friction between the pay-off roller 1 and the placement block 3. As the cable decreases, the rotation speed of the pay-off roller 1 increases continuously. At this time, the staff presses the pressure plate 10, and the pressure plate 10 drives the speed limit plate 15 and the anti-skid plate 16 to move, and the anti-skid plate 16 contacts the surface of the pay-off roller 1, and then the anti-skid plate 16 limits the rotation speed of the pay-off roller 1. The staff adjusts the rotation speed of the pay-off roller 1 by pressing it multiple times, which is convenient for controlling the speed of the pay-off, thereby achieving the effect of controlling the speed of the pay-off, and preventing the pay-off roller 1 from rotating too fast and causing too much pay-off.

[0026] Through the provided block 22, when the staff adjusts the height of the placement block 3, the staff pulls the adjustment plate 20, and then the inclined surface of the block 22 is squeezed with the inclined surface of the clamping hole 19, and then the second spring 23 is squeezed, and the block 22 enters the interior of the storage groove 21 along the direction of the guide column 24. When the staff moves the adjustment plate 20 to a suitable position, the second spring 23 rebounds and drives the block 22 to enter the interior of the clamping hole 19 again to limit the adjustment plate 20, thereby increasing the height of the support plate 2. When the staff needs to store the adjustment plate 20, the block 22 will be pushed along the guide column 24 into the interior of the storage groove 21. At this time, the staff pushes the adjustment plate 20 upward to enter the moving groove 17 The staff can then hold the support block 29 to lift the threaded column 31 out of the load-bearing block 27, and then drive the limiting frame 9 to move upward. At this time, after turning the limiting frame 9 180 degrees, the staff takes out the wire-paying roller 1 from the inside of the placement block 3, and then places the new wire-paying roller 1 inside the placement block 3. After the staff holds the support block 29 again to move the limiting frame 9 back to its original position, the staff again puts the threaded column 31 into the load-bearing block 27 of the limiting hole 30 and tightens it, which makes it easy to replace the wire-paying roller 1.
