Description

Technical Field

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

[0002] Cables are usually composed of several or several groups of conductors. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables and aluminum alloy cables, etc. They are all composed of single or multiple strands of wire and insulation layer, used to connect circuits and electrical appliances, etc. With the continuous acceleration of urbanization construction, the amount of cable laying operations has also greatly increased. During the cable laying process, it is generally carried out by tying the cable with steel wire rope for dragging or by using a pig cage to pull the cable outer sheath.

[0003] Since the diameter of the cable is larger than the diameter of the traction rope, the distance between the traction belts needs to be manually adjusted when the traction rope is transitioned to the cable, which results in a waste of the workers' physical strength when laying and traction.

[0019] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0020] according to Figure 1-5 As shown, a cable traction device for cable laying includes a base 1, on which two groups of traction mechanisms are symmetrically arranged, and the traction device includes a fixed seat 2, which is fixedly mounted on the base 1 through a support frame 14, and a slide 3 is slidably mounted on the front and rear ends of the fixed seat 2, a first spring 4 is provided between the slide 3 and the fixed seat 2, a traction conveyor belt assembly is provided on the slide 3, and a driving mechanism for driving the traction conveyor belt assembly is provided on the base 1.

[0021] In this embodiment, the fixed seat 2 is a C-shaped structure, and a slide groove 21 is respectively provided on the top wall and the bottom wall at the front and rear ends of the fixed seat 2. The slide seat 3 is slidably installed in the slide groove 21, and the first spring 4 is fixedly installed in the slide groove 21, and the other end of the first spring 4 is in contact with the slide seat 3.

[0022] In this embodiment, the traction conveyor belt assembly includes two sets of transmission shafts 5, which are rotatably mounted on the slide seats 3 at the front and rear ends of the fixed seat 2 respectively. A transmission wheel 6 is fixedly mounted on the transmission shaft 5, and a conveyor belt 7 is installed on the transmission wheel 6. Under the action of the first spring 4, the cable or traction rope is clamped by the conveyor belt 7. When the traction rope transitions to the cable, the cable will squeeze the conveyor belt 7 outward, thereby automatically adapting to cables of different diameters.

[0023] In this embodiment, an arc-shaped groove 71 is provided on the outer side surface of the conveyor belt 7 , and the arc-shaped groove 71 increases the contact area between the conveyor belt 7 and the cable, thereby preventing the cable from slipping on the conveyor belt 7 .

[0024] In this embodiment, the driving mechanism includes a motor 8, which is rigidly fixed on the side wall of the fixed base 2 through a motor bracket. A driving wheel 9 is fixedly installed on the power output shaft of the motor 8, and a driven wheel 10 is fixedly installed on the transmission shaft 5 at either end of the fixed base 2. The left and right sides of the top of the base 1 are respectively provided with mounting grooves 11, and a T-shaped slider 12 is slidably installed in the mounting groove 11. A second spring 13 is fixedly installed in the mounting groove 11, and the other end of the second spring 13 abuts against the T-shaped slider 12. A tensioning wheel 15 is rotatably installed on the T-shaped slider 12. The driving wheel 9, the driven wheel 10 and the tensioning wheel 15 are interconnected by a transmission belt 16. When the position of the conveyor belt 7 changes, under the action of the second spring 13, the transmission belt 16 is tensioned by the tensioning wheel 15, so that the motor 8 can drive the conveyor belt 7 to rotate.

[0025] In this embodiment, a bearing frame 17 is fixedly installed on the top of the front and rear ends of the base 1, and a support wheel 18 is rotatably installed on the bearing frame 17. The cable is lifted by the support wheel 18 to prevent the cable from falling downward, resulting in the cable being unable to be clamped between the conveyor belts 7 and affecting the laying.

[0026] The specific working process of the utility model is as follows: during the cable laying process, the traction rope is first clamped between the conveyor belts 7, and then the motor 8 is started. The conveyor belt 7 is driven to rotate by the motor 8, and the traction rope is conveyed forward under the action of the conveyor belt 7. When the traction rope transitions to the cable, the cable will squeeze the conveyor belts 7 on both sides outward. At this time, the slide 3 moves to both sides together with the conveyor belt 7, and at the same time, the T-shaped slide block is squeezed outward under the action of the second spring 13. The transmission belt 16 is tensioned by the tensioning wheel 15, and the cable is conveyed forward under the action of the conveyor belt 7, so that the conveyor belt 7 can automatically adapt to cables of different diameters, effectively reducing the burden on the staff.
