Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, specifically an adjustable cable laying tension control frame. Background Technology

[0002] Cable laying refers to the process of orderly and smoothly unfolding and releasing coiled or reeled cables according to construction or production needs. In many fields such as power engineering, communication engineering, and building wiring, it is necessary to release cables from their stored state (such as on a reel) and lay them in a designated location. This operation of releasing cables is called cable laying.

[0003] Cables consist of conductors, insulation layers, and sheaths. If the tension is too high during cable laying, the cable will be overstretched, causing the conductor to deform or break, affecting its conductivity. The insulation and sheaths may also be damaged or thinned, reducing the cable's insulation and protection capabilities and creating safety hazards. On the other hand, if the tension is too low, the cable is prone to loosening and tangling, resulting in knots and twists during subsequent pulling and laying. This not only increases the difficulty of construction but may also damage the cable. Therefore, tension adjustment is necessary during cable laying. Existing control frames adjust cable tension mainly by moving the tension wheel vertically. However, as the adjustment components move up and down, the overall center of gravity of the equipment will change significantly, which can easily cause the frame to sway, affecting the stability of the equipment and potentially even causing safety accidents.

The pressure sensor converts the detected pressure signal into an electrical signal and transmits it to the control system, providing a basis for subsequent precise adjustment. The second drive motor is connected to the bidirectional lead screw and receives instructions from the control system. When the control system determines the current tension of the cable body based on the signal fed back by the pressure sensor... When there is a deviation between the force and the preset tension, a control signal is sent to the second drive motor.

This ensures that the tension of the cable body is always kept within the preset range, effectively avoiding problems such as cable breakage or tangling due to improper tension. Moreover, the horizontal adjustment method can keep the cable body relatively straight during the laying process, reducing excessive bending caused by vertical undulations. The center of gravity of the entire tension adjustment component changes little, and the adjustment action will not have a significant impact on the stability of the control frame body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 One embodiment of this utility model is an adjustable cable tension control frame, comprising: a control frame body 1, and further comprising...

[0024] The wire feeding roller 3 is mounted on one side of the top of the control frame body 1 via a bracket 2, and the wire feeding roller 3 is wound with the cable body 4. A first drive motor 24 for driving the wire feeding roller 3 to rotate is fixed at one end of the bracket 2.

[0025] Both ends of the wire feeding roller 3 are fitted with limiting rings 15 to limit the cable body 4 and prevent the cable body 4 from moving axially.

[0026] A fixing rod 14 is provided between the end plates at both ends of the wire feeding roller 3. The side of the limiting ring 15 near the fixing rod 14 is connected to the fixing rod 14 through the sleeve plate 23, and the sleeve plate 23 and the fixing rod 14 are locked together by fasteners.

[0027] By sliding the sleeve 23 on the fixed rod 14, the position of the sleeve 23 and the limiting ring 15 can be adjusted, which can be adjusted according to the size of the cable body 4;

[0028] The inner sidewall of the limiting ring 15 is uniformly provided with guide balls 25, which converts the sliding friction between the wire feeding roller 3 and the limiting ring 15 into rolling friction, and can reduce frictional resistance when the limiting ring 15 is adjusted.

[0029] Adjustment seat 8 is set on the control frame body 1 on one side of the wire feeding roller 3, and the adjustment seat 8 is provided with a bidirectional lead screw 9, and the two ends of the bidirectional lead screw 9 are respectively fitted with movable sleeves 10.

[0030] Tension wheel 5, there are 2 sets of tension wheels 5, and guide wheel 6 is provided on the adjustment seat 8 between tension wheels 5. The cable body 4 passes through the top of tension wheel 5 and the bottom of guide wheel 6 in sequence, and the cable body 4 forms an S-shaped path during the cable laying process.

[0031] The cable body 4 is wound on the wire feeding roller 3 and passes through the tension wheel 5, the guide wheel 6 and the other set of tension wheels 5 in an S-shaped path. The guide wheel 6 is located between the two sets of tension wheels 5 and can provide stable guidance for the cable body 4, preventing the cable body 4 from deviating or leaving the predetermined path during the tension adjustment process.

[0032] Tension wheels 5 are respectively set on the top of movable sleeve 10 through U-shaped frame 7. Tension wheels 5 are set inside U-shaped frame 7 through roller 17, and pressure sensors 16 are set at both ends of roller 17.

[0033] The first drive motor 24 starts and drives the wire feeding roller 3 to rotate and feed the wire. The pressure sensor 16 monitors the pressure of the cable on the tension wheel 5 in real time and converts the pressure of the cable body 4 on the tension wheel 5 into an electrical signal, which is then transmitted to the control system.

[0034] The second drive motor 12 is located on one side of the adjusting seat 8, and the output end of the second drive motor 12 is connected to the bidirectional lead screw 9.

[0035] If the tension deviation exceeds the threshold, the control system sends an adjustment command to the second drive motor 12. The second drive motor 12 drives the bidirectional lead screw 9 to rotate, driving the movable sleeves 10 on both sides to move axially. The movable sleeves 10 drive the tension wheels 5 to move closer or further away synchronously through the U-shaped frame 7, changing the cable wrap angle and the degree of tension. If the distance between the tension wheels 5 is reduced, the tension of the cable body 4 will decrease, and vice versa.

[0036] This ensures that the tension of the cable body 4 is always kept within the preset range, effectively preventing problems such as cable body 4 breaking or tangling due to improper tension. Moreover, the horizontal adjustment method can keep the cable body 4 relatively straight during the cable laying process, reducing excessive bending caused by vertical fluctuations. The center of gravity of the entire tension adjustment component changes little, and the adjustment action will not have a significant impact on the stability of the control frame body 1.

[0037] The bottom of the movable sleeve 10 is provided with a guide block 11, and the bottom of the adjusting seat 8 is provided with two sets of guide grooves that match the guide block 11, which can effectively limit the movement direction of the movable sleeve 10 and prevent it from swaying or deviating laterally.

[0038] Each movable sleeve 10 has a buffer seat 13 at its top, and each buffer seat 13 has a movable plate 22 inside it via an elastic body 19. The top of each movable plate 22 is connected to the U-shaped frame 7.

[0039] All elastomers 19 are made of rubber, which has good elasticity and cushioning properties and can effectively absorb the impact and vibration caused by the change in position of tension wheel 5 or the sudden change in tension of cable body 4 during the tension adjustment process.

[0040] Furthermore, a through groove 20 is provided at the center of the elastomer 19, and a support column 21 is embedded in the through groove 20 to improve the structural strength of the elastomer 19 and prevent excessive deformation of the elastomer 19 while providing cushioning.

[0041] Limiting blocks 18 are provided on both sides of the movable plate 22, and limiting grooves matching the limiting blocks 18 are provided on both sides inside the buffer seat 13. The movable plate 22 can move slightly adaptively within the buffer seat 13 according to the tension change of the cable body 4. Through the cooperation of the limiting blocks 18 and the limiting grooves, the movement of the movable plate 22 is ensured to be stable.

[0042] The specific models and specifications of the first drive motor 24, the second drive motor 12, and the pressure sensor 16 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0043] Working Principle: In this embodiment, the cable body 4 is wound around the pay-off roller 3 and passes through the tension wheel 5, below the guide wheel 6, and above another set of tension wheels 5, forming an S-shaped path. The limiting rings 15 at both ends of the pay-off roller 3 limit the cable body 4 to prevent axial movement. By sliding the sleeve 23 on the fixed rod 14, the position of the sleeve 23 and the limiting ring 15 can be adjusted according to the size of the cable body 4. The guide balls 25 on the inner wall of the limiting ring 15 convert the sliding friction between the pay-off roller 3 and the limiting ring 15 into rolling friction. Adjusting the position of the limiting ring 15 reduces frictional resistance. The first drive motor 24 starts, driving the pay-off roller 3 to rotate and pay off the cable. The pressure sensor 16 monitors the pressure of the cable on the tension wheel 5 in real time and converts the pressure of the cable body 4 on the tension wheel 5 into an electrical signal, which is transmitted to the control system. If the tension deviation exceeds the threshold, the control system sends a signal to the second drive motor 12. Upon receiving the adjustment command, the second drive motor 12 drives the bidirectional lead screw 9 to rotate, driving the movable sleeves 10 on both sides to move axially. The movable sleeves 10, through the U-shaped frame 7, drive the tension wheels 5 to move closer or further away synchronously, changing the cable wrap angle and tension. When the distance between the tension wheels 5 decreases, the tension of the cable body 4 decreases, and vice versa. The elastic body 19 in the buffer seat 13 can effectively absorb the impact and vibration caused by the change in position of the tension wheels 5 or the sudden change in tension of the cable body 4 during the tension adjustment process. The rubber elastic body 19 has good elasticity and buffering performance. With the structural design of the through groove 20 and the support column 21, it avoids excessive deformation of the elastic body 19 while buffering, preventing the cable body 4 from being worn on the surface or damaged in the internal structure due to vibration. The movable plate 22 can move slightly adaptively within the buffer seat 13 according to the change in tension of the cable body 4. Through the cooperation of the limit block 18 and the limit groove, the movement of the movable plate 22 is ensured to be stable.
