Description

Technical Field

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

[0002] In the field of power engineering construction and cable laying operations, traditional technical solutions have revealed numerous problems affecting construction safety and cable quality in actual operation. When laying cables into cable wells using conventional methods, the lack of effective support and guiding devices causes the cable to continuously rub against the edge of the cable well during the release process. This mechanical friction easily causes wear and scratches on the cable sheath, especially when there are burrs or unevenness at the edge of the well, significantly increasing the risk of sheath damage, which in turn leads to a decrease in cable insulation performance and creates safety hazards such as leakage and short circuits for subsequent operation. In existing technologies, the control of cable release speed mainly relies on the force of manual operation of the drum, but manual operation is difficult to achieve precise control. When construction workers pull the cable too hard, the drum will continuously release excessive cable due to inertia, causing the cable to accumulate and become chaotic in the well. This not only increases the workload of subsequent cleanup but may also cause problems such as limited working space and obstruction of equipment operation due to cable entanglement. To address the above technical defects, those skilled in the art have proposed a solution for a cable laying device. Utility Model Content

[0003] The purpose of this utility model is to provide a technical solution for a cable laying device to address the shortcomings mentioned in the background art. To overcome the drawbacks and defects described in the background art, this technical solution includes the following:

[0004] The cable reel frame includes a cable laying stabilizer fixedly connected to the front side wall of the cable reel frame; the cable reel frame includes a steel support, drum baffles rotatably disposed on the left and right sides of the top of the steel support, and a drum fixedly connected between the drum baffles, with a cable wound around the outer ring of the drum.

[0005] The cable laying stabilizer includes a fixed wheel and a movable wheel. A connecting rod is rotatably connected to the left side of the fixed wheel. A screw passes through the end of the connecting rod away from the fixed wheel. A bearing is fixedly connected to the right end of the screw. A rotating shaft is fixed inside the inner ring of the bearing. The end of the rotating shaft away from the bearing is fixedly connected to the left side wall of the movable wheel. A support rod is rotatably connected to the right side wall of the fixed wheel. The bottom end of the support rod is fixedly connected to the front side wall of the steel bracket.

[0006] As a preferred embodiment of this utility model, a groove for clamping the outer surface of the cable is formed on the outer circumference surface of both the fixed wheel and the movable wheel.

[0007] As a preferred embodiment of this utility model, the end of the screw away from the connecting rod is fixedly connected to the left side wall of the outer ring of the bearing.

[0008] As a preferred embodiment of this utility model: a rubber ring is fixedly connected to the right section of the screw, and the left sidewall of the rubber ring is in close contact with the right sidewall of the connecting rod.

[0009] As a preferred embodiment of this utility model: a nut is screwed onto the left section of the screw, and the right side wall of the nut is in close contact with the left side wall of the connecting rod.

[0010] As a preferred embodiment of this utility model, the connecting rod has a strip-shaped through hole for the screw to move inside.

[0011] As a preferred embodiment of this utility model: a clamp is fixed on the crossbar of the left side wall of the steel bracket, and a pin passes through the inside of the clamp.

[0012] As a preferred embodiment of this utility model: four fixing plates are fixedly connected in a ring array on the outer surface of the drum edge, and each fixing plate has a through hole for the pin to pass through, so as to limit the rotation of the drum by inserting the pin.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] In this design, the fixed and movable wheels of the cable laying stabilizer work together. Their outer grooves clamp and elevate the cable, preventing the cable sheath from rubbing against the well edge during laying, reducing the risk of cable sheath damage and extending cable life. By rotating the nut to adjust the position of the connecting rod on the screw, the distance between the movable and fixed wheels can be changed, thereby controlling the clamping force on the cable. Friction is used to adjust the cable release speed, preventing the drum from releasing too much cable due to inertia when pulling the cable forcefully, ensuring a smooth and orderly laying process. The clamps, pins, and drum side fixing plates on the steel bracket can restrict drum rotation when necessary, promptly stopping the cable from continuing to release, providing safety for personnel working in cable wells.

The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0022] Example 1: A cable laying device includes a cable reel frame 1, and a cable laying stabilizer 2 is fixedly connected to the front side wall of the cable reel frame 1. The cable reel frame 1 includes a steel support 101, and drum baffles 104 are rotatably arranged on the left and right sides of the top of the steel support 101. Drums 103 are fixedly connected to each other between the drum baffles 104, and a cable 102 is wound around the outer ring of the drum 103. The cable laying stabilizer 2 includes a fixed wheel 201 and a movable wheel 203. A connecting rod 208 is rotatably connected to the left side of the fixed wheel 201. The end of the connecting rod 208 away from the fixed wheel 201 passes through a screw 209. The right end of the screw 209 is fixedly connected to the left side wall of the outer ring of a bearing 202. A rotating shaft 204 is fixed inside the inner ring of the bearing 202. The end of the rotating shaft 204 away from the bearing 202 is fixedly connected to the left side wall of the movable wheel 203. A support rod 206 is rotatably connected to the right side wall of the fixed wheel 201. The bottom end of the support rod 206 is fixedly connected to the front side wall of a steel bracket 101. A groove is formed on the outer surface of both the fixed wheel 201 and the movable wheel 203 to clamp the outer surface of the cable 102. A rubber ring 205 is fixedly connected to the right section of the screw 209. The left sidewall of the rubber ring 205 is in close contact with the right sidewall of the connecting rod 208. A nut 207 is screwed onto the left section of the screw 209. The right sidewall of the nut 207 is in close contact with the left sidewall of the connecting rod 208. A slotted through hole for the screw 209 to move is opened inside the connecting rod 208. A clamp 106 is fixed to the crossbar on the left sidewall of the steel bracket 101. A pin 105 passes through the clamp 106. Four fixing plates 107 are fixedly connected in a ring array on the outer surface of the drum flange 104. A through hole for the pin 105 to pass through is opened inside the fixing plate 107.

[0023] When laying cables to the cable well, first place the cable reel frame 1 in a suitable position, then lead the cable 102 out from the drum 103, passing it through the groove between the fixed wheel 201 and the movable wheel 203. By adjusting the position of the adjusting nut 207 on the screw 209, the distance between the connecting rod 208 and the bearing 202 is changed, thereby adjusting the clamping force of the movable wheel 203 and the fixed wheel 201 on the cable 102. When it is necessary to release the cable, pull the cable with the force controlled according to the actual needs. Since the cable is clamped and raised by the cable laying stabilizer 2, the cable sheath will not rub against the edge of the cable well. When it is necessary to restrict the rotation of the drum 103, insert the pin 105 into the clamp 106, making it pass through the through hole of the fixing plate 107 on the drum side 104, thereby preventing the drum 103 from rotating and avoiding excessive cable release due to inertia after pulling the cable with force, ensuring the safety of personnel working in the cable well.

[0024] Example 2: A cable laying device, also including a cable reel frame 1 and a cable laying stabilizer 2 fixed to its front side wall. A drum guard 104 is rotatably mounted on the steel support 101 of the cable reel frame 1, and a drum 103 is fixed between the drum guards 104, with the drum 103 winding around the cable 102. In the cable laying stabilizer 2, a fixed wheel 201 cooperates with a screw 209 via a connecting rod 208 on the left side. The right end of the screw 209 is connected to a movable wheel 203 via a bearing 202 and a rotating shaft 204. The right side of the fixed wheel 201 is connected to the steel support 101 via a support rod 206. The outer rings of the fixed wheel 201 and the movable wheel 203 have grooves for clamping the cable 102. The screw 209 has a rubber ring 205 and a nut 207, and the connecting rod 208 has a strip-shaped through hole for the screw 209 to move. The steel bracket 101 has a clamp 106 and a pin 105 on the left crossbar, and the drum edge 104 has a fixing piece 107 with a through hole.

[0025] In practical use, the cable reel frame 1 is transported to the vicinity of the cable well, and the cable 102 is led out and placed between the fixed wheel 201 and the movable wheel 203. By rotating the nut 207, the tightness of the contact between the rubber ring 205 and the connecting rod 208 is changed, thereby adjusting the pressure of the movable wheel 203 on the cable 102 and realizing the adjustment of the clamping force. During the cable laying process, the cable laying stabilizer 2 raises the cable so that it does not contact the edge of the cable well. When it is necessary to stop the cable release in special circumstances, the pin 105 is quickly inserted into the clamp 106 and passes through the through hole of the fixing plate 107 to restrict the rotation of the drum 103, prevent the cable from continuing to release due to inertia, and ensure operational safety.

[0026] Example 3: A cable laying device includes a cable reel frame 1 and a cable laying stabilizer 2 disposed on its front side. The cable reel frame 1 consists of a steel support 101, drum baffles 104 rotatably mounted on both sides of the top of the steel support 101, a drum 103 fixed between the drum baffles 104, and a cable 102 wound on the drum 103. In the cable laying stabilizer 2, a connecting rod 208 is connected to the left side of the fixed wheel 201, and the connecting rod 208 cooperates with a screw 209. The right end of the screw 209 is connected to the movable wheel 203 through a bearing 202 and a rotating shaft 204. The right side of the fixed wheel 201 is connected to the steel support 101 through a support rod 206. Grooves for clamping the cable 102 are formed on the outer rings of the fixed wheel 201 and the movable wheel 203. A rubber ring 205 and a nut 207 are provided on the screw 209, and a strip-shaped through hole is formed on the connecting rod 208. The steel bracket 101 has a clamp 106 and a pin 105 on the left crossbar, and the drum edge 104 has a fixing piece 107 with a through hole.

[0027] Before cable laying, check that all components of the device are intact. After placing the cable reel frame 1 stably, lead the cable 102 out of the drum 103 and place it in the grooves of the fixed wheel 201 and the movable wheel 203. According to the cable specifications and laying requirements, adjust the position of the nut 207 on the screw 209 to change the contact pressure between the rubber ring 205 and the connecting rod 208, thereby adjusting the clamping force of the movable wheel 203 on the cable 102. During the laying process, the cable laying stabilizer 2 raises the cable to avoid friction with the edge of the cable well. If it is necessary to pause cable release, the operator can quickly insert the pin 105 into the clamp 106 and through the through hole of the fixing plate 107 to limit the rotation of the drum 103, prevent the cable from being released too much due to inertia, and ensure the safety of personnel working in the cable well.

[0028] Based on the above-described preferred technical solution, the workflow of the technical solution is explained as follows: In the cable reel frame 1, the steel bracket 101 serves as the overall support structure, the drum baffle 104 is rotatably set on the left and right sides of the top of the steel bracket 101, the drum 103 is fixedly connected between the sides of the drum baffle 104 that are close to each other, and the cable 102 is wound on the outer ring of the drum 103. The cable laying stabilizer 2 is fixed on the front side wall of the cable reel frame 1. It includes a fixed wheel 201 and a movable wheel 203. The left side of the fixed wheel 201 is rotatably connected to a connecting rod 208. A strip-shaped through hole is opened at the end of the connecting rod 208 away from the fixed wheel 201. A screw 209 passes through the strip-shaped through hole. The right end of the screw 209 is fixedly connected to the left side wall of the outer ring of the bearing 202. A rotating shaft 204 is fixed inside the inner ring of the bearing 202. The end of the rotating shaft 204 away from the bearing 202 is fixedly connected to the left side wall of the movable wheel 203. In this way, the movable wheel 203 can rotate through the rotating shaft 204 and the bearing 202, and its position can be adjusted with the cooperation of the screw 209 and the connecting rod 208. The right side wall of the fixed wheel 201 is rotatably connected to a support rod 206. The bottom end of the support rod 206 is fixedly connected to the front side wall of the steel bracket 101 to support the fixed wheel 201. Both the fixed wheel 201 and the movable wheel 203 have a groove on their outer surface to hold the outer surface of the cable 102. After the cable 102 is led out from the drum 103, it passes through the groove. The cable can be raised by the clamping of the fixed wheel 201 and the movable wheel 203. The right section of the screw 209 is fixedly connected to a rubber ring 205. The left sidewall of the rubber ring 205 is in close contact with the right sidewall of the connecting rod 208. The left section of the screw 209 is screwed with a nut 207. The right sidewall of the nut 207 is in close contact with the left sidewall of the connecting rod 208. By rotating the nut 207, the degree of compression of the connecting rod 208 by the nut 207 and the rubber ring 205 can be changed, thereby changing the position of the connecting rod 208 on the screw 209. The distance between the movable wheel 203 and the fixed wheel 201 can be adjusted to adjust the clamping force of the cable 102. Different clamping forces will affect the friction when the cable is released, thereby controlling the speed of cable release and preventing the drum 103 from releasing too much cable due to inertia after pulling the cable forcefully. A clamp 106 is fixed on the crossbar of the left side wall of the steel bracket 101. A pin 105 passes through the inside of the clamp 106. Four fixing plates 107 are fixedly connected in a ring array on the outer surface of the drum sidewall 104. The fixing plates 107 have through holes for the pin 105 to pass through. When it is necessary to restrict the rotation of the drum 103, the pin 105 is inserted into the clamp 106 and passes through the through hole of the fixing plate 107. The cooperation between the pin 105 and the fixing plate 107 prevents the drum sidewall 104 from rotating, thereby restricting the rotation of the drum 103, preventing the cable from continuing to be released, and ensuring the safety of personnel working in the cable well.During the cable laying process, after the cable 102 is led out from the drum 103, it passes through the groove between the fixed wheel 201 and the movable wheel 203. The cable laying stabilizer 2 clamps and lifts the cable to prevent the cable sheath from rubbing against the edge of the cable well. At the same time, the clamping force and release speed of the cable are controlled by adjusting the nut 207. If necessary, the pin 105 is used to restrict the rotation of the drum 103.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
