Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable traction device. Background Technology

[0002] Electricity is essential to our lives, and cable tunnels are inextricably linked to electricity. A cable tunnel is a tunnel used for laying cables. Cable tunnels have many advantages, the most obvious of which is that they are a one-time investment. There are many cable supports inside the tunnel, and after the tunnel is built, it only needs to be inspected regularly.

[0003] However, in the existing technology, when using a cable pulling device to pull a cable, the cable may fall out of the device due to its rebound force when the pulling is stopped, causing workers near the device to be injured by the ejected cable. Secondly, the width of some cable pulling devices is fixed, which makes it impossible to effectively pull different types of cables. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable traction device, comprising: a base plate, with legs installed at all four ends of the bottom of the base plate, a fixing groove in the middle of the top of the base plate, a width adjustment device inside the fixing groove, fixing holes in all four ends of the top of the base plate, the four fixing holes being divided into two groups, a blocking device inside each group of fixing holes, and a placement plate groove installed at the top of the inner cavity of the fixing groove.

[0006] Furthermore, the interior of both sets of fixing holes is provided with four limiting grooves, and fastening bolts are threaded through both ends of both sides of the base plate. A controller is installed on one side of the base plate, and both ends of the bottom of the placement plate groove are embedded in the top ends of the base plate.

[0007] Furthermore, the width adjustment device includes a forward and reverse motor, the output end of which is fixedly connected to a bidirectional threaded rod. Two movable plates are threadedly fitted onto the surface of the bidirectional threaded rod. Guide rods are embedded through both ends of the two movable plates. A fixed box is installed on the top of each of the two movable plates. Five rotating rods are installed equidistantly inside the two fixed boxes via bearings.

[0008] Furthermore, a double-groove pulley is fixedly fitted at the bottom of the surface of each of the multiple rotating rods. The multiple double-groove pulleys are divided into two groups on average. Four transmission belts are alternately fitted inside the two groups of double-groove pulleys. Rollers are fixedly fitted at the top of the surface of each of the multiple rotating rods. A motor is installed at the bottom end of each of the two rotating rods.

[0009] Furthermore, one end of the forward and reverse motor is installed in the middle of one side of the base plate, one end of the surface of the bidirectional threaded rod is movably inserted through the surface of the base plate, and the other end of the bidirectional threaded rod is installed on one side inside the fixed groove through a bearing. Both ends of the two guide rods are installed on both sides inside the fixed groove, and the surfaces of the two motors penetrate the two fixed boxes and are fixedly embedded on the top of the two movable plates.

[0010] Furthermore, the blocking device includes two lifting columns, each with four limit blocks equidistantly installed on its surface, a connecting column installed at the top of the two lifting columns, and a rotating cylinder installed in the middle of the connecting column via a bearing.

[0011] Furthermore, the surfaces of the two lifting columns are movably embedded inside the two fixing slots, and the surfaces of the multiple limiting blocks are movably embedded inside the limiting slots located at the same end.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model loosens the lifting column by rotating the fastening bolts, and then pushes the lifting column to rise and fall along the direction of the fixing hole, the limiting block and the limiting groove. The height is adjusted so that the bottom surface of the rotating drum is in contact with the top surface of the cable. Then the fastening bolts are rotated to tighten the lifting column. This avoids the phenomenon that the cable will fall out of the equipment due to the rebound force when the cable stops pulling, which would cause the staff near the equipment to be injured by the ejected cable.

[0014] 2. In this utility model, the controller starts the forward and reverse motors and the motor. The forward and reverse motors drive the bidirectional threaded rod to rotate, which in turn drives the moving plate and the fixed box to move along the direction of the guide rod. When the surface of the brake roller presses against the surface of the cable, it stops. Then, the motor drives the rotating rod and the double groove pulley to rotate, which in turn drives the transmission belt and multiple rollers to rotate. The rotation of the rollers drives the cable to be pulled. This also avoids the situation where the width of some cable pulling equipment is fixed, which makes it impossible to effectively pull different types of cables. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a cable traction device, comprising: a base plate 1, with support legs 101 installed at all four ends of the bottom of the base plate 1, a fixing groove 106 opened in the middle of the top of the base plate 1, a width adjustment device 2 provided inside the fixing groove 106, fixing holes 103 opened at all four ends of the top of the base plate 1, the four fixing holes 103 being divided into two groups, a blocking device 3 being provided inside the two groups of fixing holes 103, and a placement plate groove 102 installed at the top of the inner cavity of the fixing groove 106.

[0025] Specifically: the width adjustment device 2 is used to adjust the cable according to different cable models, and the blocking device 3 is used to restrain the cable that has stopped pulling.

[0026] In one embodiment, four limiting grooves 104 are provided around the interior of both sets of fixing holes 103, fastening bolts 105 are threaded through both ends of both sides of the base plate 1, a controller is installed on one side of the base plate 1, and both ends of the bottom of the placement plate groove 102 are embedded in the top ends of the base plate 1.

[0027] Specifically, such as Figure 1-3 As shown: the blocking device 3 is limited by the fixing hole groove 103 and the limiting groove 104, and the fastening bolt 105 is used to fix and loosen the blocking device 3, thus playing the role of limiting and fixing.

[0028] In one embodiment, the width adjustment device 2 includes a forward and reverse motor 201. The output end of the forward and reverse motor 201 is fixedly connected to a bidirectional threaded rod 202. Two movable plates 203 are threadedly sleeved on the surface of the bidirectional threaded rod 202. Guide rods 204 are embedded through both ends of the two movable plates 203. Fixed boxes 205 are installed on the top of the two movable plates 203. Five rotating rods 206 are installed equidistantly inside the two fixed boxes 205 through bearings.

[0029] Specifically, such as Figure 1-5 As shown: The forward and reverse motors 201 drive the moving plate 203 and the fixed box 205 to move along the direction of the guide rod 204, which plays a role in adjusting the width.

[0030] In one embodiment, a double-groove pulley 207 is fixedly fitted on the bottom of the surface of a plurality of rotating rods 206. The plurality of double-groove pulleys 207 are divided into two groups. Four transmission belts 208 are alternately fitted inside the two groups of double-groove pulleys 207. Rollers 209 are fixedly fitted on the top of the surface of a plurality of rotating rods 206. A motor 210 is installed at the bottom end of two rotating rods 206.

[0031] Specifically, such as Figure 1-5 As shown: the motor 210 drives the roller 209 to rotate, which plays a role in pulling the cable.

[0032] In one embodiment, one end of the forward and reverse motor 201 is installed in the middle of one side of the base plate 1, one end of the surface of the bidirectional threaded rod 202 is movably inserted through the surface of the base plate 1, and the other end of the bidirectional threaded rod 202 is installed on one side inside the fixed groove 106 through a bearing. Both ends of the two guide rods 204 are installed on both sides inside the fixed groove 106. The surfaces of the two motors 210 are inserted through the two fixed boxes 205 and fixedly embedded on the top of the two movable plates 203.

[0033] Specifically, such as Figure 1-4 As shown: The forward and reverse motor 201, the bidirectional threaded rod 202, the guide rod 204 and the motor 210 are fixed by the base plate 1, the fixing groove 106 and the moving plate 203, which plays a fixing role.

[0034] In one embodiment, the blocking device 3 includes two lifting columns 301, four limiting blocks 302 are equidistantly installed on the surface of each of the two lifting columns 301, a connecting column 303 is installed on the top of the surface of the two lifting columns 301, and a rotating cylinder 304 is installed in the middle of the surface of the connecting column 303 via a bearing.

[0035] Specifically, such as Figure 3 and 6 As shown: The cable is limited by the lifting column 301 and the rotating drum 304, which serves to block it.

[0036] In one embodiment, the surfaces of the two lifting columns 301 are movably embedded inside the two fixing slots 103, and the surfaces of the multiple limiting blocks 302 are movably embedded inside the limiting slots 104 located at the same end.

[0037] Specifically, such as Figure 3 and 6 As shown: The lifting column 301 and the limiting block 302 are connected and limited through the fixing hole groove 103 and the limiting groove 104, which plays a limiting role.

[0038] Working principle:

[0039] Place the equipment on a flat surface. The forward and reverse motors 201 and 210 are electrically connected to the controller and connected to an external power source. By pushing one end of the cable along one end of the surface of the placement plate groove 102 to the other end, the lifting column 301 is loosened by rotating the fastening bolt 105. Then, the lifting column 301 is pushed up and down along the direction of the fixing hole groove 103, the limit block 302 and the limit groove 104. Adjust the height so that the bottom surface of the rotating drum 304 is in contact with the top surface of the cable. Then, rotate the fastening bolt 105 to tighten the lifting column 301. This prevents the cable from falling out of the equipment due to the rebound force when the cable stops being pulled, thus avoiding the phenomenon that the personnel near the equipment will be injured by the ejected cable.

[0040] When pulling the cable, the controller starts the forward and reverse motors 201 and 210. The forward and reverse motors 201 drive the bidirectional threaded rod 202 to rotate, while the moving plate 203 and the fixed box 205 move along the direction of the guide rod 204. When the surface of the brake roller 209 presses against the surface of the cable, it stops. Then, the motor 210 drives the rotating rod 206 and the double groove pulley 207 to rotate, while the transmission belt 208 and multiple rollers 209 rotate. The rotation of the rollers 209 drives the cable to be pulled. This also avoids the situation where the width of some cable pulling equipment is fixed, which would prevent different types of cables from being effectively pulled.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
