[0010] The utility model also has the following specific features:

[0011] The outer surface of the mounting plate is provided with four mounting holes, and the four mounting holes are respectively located at the four corners of the upper surface of the mounting plate.

[0012] The piston structure comprises a first piston, which is arranged in the interior of the cylinder body, and one side of the outer surface of the first piston is fixedly connected with one end of the movable rod, and the other end of the movable rod is fixedly connected with one side of the outer surface of the supporting plate.

[0013] The elastic structure comprises two rectangular sleeves and a fixed plate, the top of the outer surface of the two rectangular sleeves is fixedly connected with the bottom of the outer surface of the same fixed frame, the inner surfaces of the two rectangular sleeves are respectively slidably connected with the outer surfaces of two rectangular plates, the left and right sides of the outer surfaces of the two rectangular plates are fixedly connected with the fixed blocks, and the bottoms of the outer surfaces of the four fixed blocks are fixedly connected with the top of the outer surface of the mounting plate.

[0014] The outer surfaces of the two fixed blocks on the left and the two fixed blocks on the right are respectively fixedly connected with one end of the two touch rods, the opposite surfaces of the two fixed blocks on the left and the two fixed blocks on the right are respectively fixedly connected with the two sides of the two side plates, the alarm is arranged on one side of the side plate, the first switch is arranged on the other side of the side plate, the outer surface of the rectangular plate is sleeved with two first springs, and the two ends of the two first springs are respectively fixedly connected with the two sides of the rectangular sleeve and one side of the two fixed blocks.

[0015] The opposite surfaces of the two handles are respectively fixedly connected with the opposite surfaces of the outer surface of the screw rod, the threads on the two sides of the outer surface of the screw rod are oppositely arranged, the two sides of the inner wall of the fixed frame are respectively fixedly connected with the two sides of the outer surface of the guide plate, the outer surface of the guide plate is slidably connected with the inner surfaces of the two guide sleeves, and the two guide sleeves are respectively clamped in the interiors of the two supporting plates.

[0017] The use method of the cable positioning and locking device comprises the following steps:

[0018] S1. In use, first turn the handle to rotate the screw, which in turn moves the two nuts closer together. This causes the two nuts to move the two support plates closer together, which in turn moves the two support plates to move the two movable rods. The two movable rods then move the first piston inside the cylinder. Since the cylinder and cylindrical tube contain liquid, the first piston can press the liquid into the cylindrical tube, which in turn moves the second piston. This moves the second piston, which in turn moves the connecting rod, which in turn moves the connecting plate, which in turn moves the hole sleeve. At the same time, the connecting plate pulls the rope, which moves the connecting block, causing the second spring to deform. This causes the two hole sleeves to separate, which in turn moves the support frame, which in turn moves the arc plate, causing the two arc plates to move away from each other. Simultaneously, the hole sleeves move the two rollers away from each other. Because the gap between the two clamping plates is large, they will not close. Even after the two arc plates open, the gap between the clamping plates still ensures that the cable can be inserted smoothly.

[0019] S2. Then, place the cable between the two arc-shaped plates from top to bottom and rotate the handle in the opposite direction. This causes the screw to move the two nuts away from each other, allowing the two support plates to reset the movable rod, which in turn resets the first piston. The second piston then pushes the connecting rod to move, which in turn pushes the connecting plate to move, loosening the cable. At this point, the elastic force of the second spring pushes the connecting block to move, and the connecting plate moves the hole sleeve. The hole sleeve then moves the arc-shaped plate through the support frame, causing the two arc-shaped plates to close together. Simultaneously, the two hole sleeves move the two rollers closer together to fit the cable. Now, the cable can be dragged for cable transfer. The cable cleaning ring can clean the surface of the cable. If the roller gets stuck while the cable is being dragged, the friction between the cable and the roller increases, generating heat. This heat causes the internal gas to expand and enter the shell through the through hole, causing the piston rod to move upward and trigger the second switch. The second switch then controls the alarm to sound, allowing relevant personnel to be alerted in time.

[0020] S3. After the cable transmission is completed, turn the handle to drive the screw to rotate, causing the two nuts to move closer to each other, the two connecting plates to move closer to each other, and the two clamping plates to move closer to each other. This allows the two clamping plates to clamp the cable. When the cable is clamped and subjected to external tension, the clamping plates lock the cable, causing the cable to drag the clamping plates and support plates to move. This causes the support plates to move the first bearing and the fixing frame through the nuts and screw, causing the rectangular sleeve to slide and the first spring to deform. At the same time, the contact rod touches the first switch, causing the first switch to control the alarm to sound, so that relevant personnel can discover and deal with the situation in a timely manner.

[0021] The beneficial effects of this invention are as follows: By setting up a clamping structure, a control device, a guide overheat alarm structure, and a cleaning ring, this invention allows the clamping structure and control device to work together to smoothly separate the two cleaning rings, thereby facilitating the placement of the cable. At the same time, by closing the two cleaning rings, a good supporting effect can be provided when dragging the cable. Meanwhile, the cleaning ring and the guide overheat alarm structure can reduce cable wear and prevent cable breakage and damage. Thus, this device, through the cooperation of the clamping structure and control device, not only facilitates the placement of the cable but also locks the cable in place, ensuring the stability of the cable installation.

[0022] This invention, by incorporating a clamping structure, a control device, a guide overheat alarm structure, and a cleaning ring, allows the clamping structure and control device to work together to smoothly separate the two cleaning rings, facilitating cable placement. Simultaneously, by closing the two cleaning rings, it provides good support when dragging the cable. Furthermore, the cleaning rings and the guide overheat alarm structure reduce cable wear and tear, preventing cable breakage and damage. Thus, this device, through the cooperation of the clamping structure and control device, not only facilitates cable placement but also locks the cable in place, ensuring the stability of the cable installation.

[0023] This invention, by setting up an elastic structure, a first switch, and an alarm, allows the elastic structure to resist the external force when the cable is pulled, reducing the drag on the cable. At the same time, if the external force is large, the movement of the contact rod can trigger the first switch, which in turn controls the alarm to sound, making it easier for relevant personnel to discover the problem in time and perform inspection and maintenance immediately, thereby reducing economic losses.

[0024] This invention incorporates a guided overheat alarm structure. When the roller becomes stuck, the increased friction between the roller and the cable causes the gas inside the roller to expand. This gas then controls a piston rod to activate a second switch, which in turn triggers an alarm. This alerts relevant personnel to the cable dragging and friction, allowing for timely inspection and handling. This prevents damage to the cable surface caused by prolonged dragging, thus reducing the cable's lifespan.

[0025] This invention, by setting up a control device, allows the two arc-shaped plates to be smoothly separated under the action of the clamping structure, facilitating cable placement. This process does not affect the clamping structure's locking of the cable. Furthermore, the hydraulic fluid drive of the control device can control the movement of the two second pistons, and the hydraulic pull can control the rope movement. Thus, this device can achieve the opening and closing of multiple sets of arc-shaped plates on the left and right sides without the need for other external forces. The hydraulic drive makes the entire process simpler and faster. Attached Figure Description

Detailed Implementation

[0035] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0036] like Figures 1-8 As shown, this invention provides a cable positioning and locking device and method for building electromechanical installation with compressible cable transmission. It includes a mounting plate 1, a control device 6 disposed on the front side of the outer surface of the mounting plate 1, and a clamping structure 5 disposed at one end of the control device 6. By configuring the control device 6 and the clamping structure 5, the clamping structure 5 can drive the control device 6 to move, thereby smoothly opening the arc-shaped plate 12, further facilitating the placement of the cable between the two arc-shaped plates 12. Simultaneously, the clamping structure 5, in conjunction with the control device 6, can drive the two arc-shaped plates 12 to close, thus providing effective support for the cable. Furthermore, the clamping structure 5 can secure the cable... The position is locked to ensure cable stability. The bottom of the outer surface of the clamping structure 5 is fixedly connected to the top of the outer surface of the elastic structure 9. By setting the elastic structure 9, when the cable is pulled by an external force, the elastic structure 9 can resist the external force and reduce the drag on the cable. The elastic structure 9 is set on the upper surface of the mounting plate 1. The two sides of the elastic structure 9 are fixedly connected to one end of the opposite face of the two contact rods 4 respectively. The two sides of the outer surface of the elastic structure 9 are provided with a first switch 14. By setting the first switch 14, it is convenient to control the alarm 3 to alarm, so that the staff can discover and inspect the cable in time.

[0037] Two alarms 3 are provided on the surface of the elastic structure 9. The top of the outer surface of the control device 6 is fixedly connected to two connecting brackets 7. Two hole sleeves 10 are slidably connected to the outer surface of each of the two connecting brackets 7. By setting the connecting brackets 7 and the hole sleeves 10, the connecting brackets 7 can guide the hole sleeves 10, so that the hole sleeves 10 can slide smoothly. The upper surface of the hole sleeve 10 is provided with a guide overheat alarm structure 8. By setting the guide overheat alarm structure 8, the rolling of the guide overheat alarm structure 8 can reduce the friction between it and the cable, thereby facilitating the sliding of the cable. The two sides of the outer surface of the hole sleeve 10 are fixedly connected to one end face of two support brackets 13 respectively. The other end face of the two support brackets 13 is fixedly connected to the bottom of the outer surface of two arc plates 12 respectively. The two adjacent arc plates 12 overlap. A cleaning ring 11 is fixedly connected to the inner side of the arc plate 12. By setting the cleaning ring 11, and the cleaning ring 11 having a certain degree of softness, the wear between it and the cable can be reduced. At the same time, the cleaning ring 11 can clean the surface of the cable.

[0038] The control device 6 includes a cylinder 67 and two piston structures 61. The two piston structures 61 are disposed inside the cylinder 67. Both sides of the outer surface of the cylinder 67 are connected to one end of two connecting pipes 68, which connect the cylinder 67 and the cylindrical tube 62. The other ends of the two connecting pipes 68 are connected to the two cylindrical tubes 62. A bracket 66 is fixedly connected to the bottom of the outer surface of each cylindrical tube 62, which secures the cylindrical tube 62. The bracket 66 is fixedly connected to the surface of the mounting plate 1. A second piston 63 is disposed inside each cylindrical tube 62, ensuring a tight seal between the second piston 63 and the cylindrical tube 62 to prevent air leakage. One side of the outer surface of each second piston 63 is fixedly connected to one end of two connecting rods 64. The connection is fixed by setting connecting rods 64, which can connect the second piston 63 and the connecting plate 65. The other ends of the two connecting rods 64 are fixedly connected to one side of the outer surface of the two connecting plates 65 respectively. The top of the upper surface of the two connecting plates 65 is fixedly connected to the bottom of the outer surface of the two hole sleeves 10 respectively. A rope 15 is fixedly connected to the back of the connecting plate 65. The rope 15 is slidably connected to the pulley 16. By setting the pulley 16, the pulley 16 can ensure the smooth sliding of the rope 15. The back of the pulley 16 is fixedly connected to the support frame 7. One side of the inner wall of the support frame 7 is fixedly connected to the second spring 17. By setting the second spring 17, the elastic force of the second spring 17 can drive the connecting block 18 to return to its original position smoothly. One end of the second spring 17 is fixedly connected to the connecting block 18. The upper surface of the connecting block 18 is fixedly connected to the lower surface of the hole sleeve 10 behind it.

[0039] The clamping structure 5 includes a fixing frame 55, which supports and fixes the first bearing 53. The first bearing 53 is clamped onto both sides of the outer surface of the fixing frame 55, supporting the screw 51 and ensuring its smooth rotation. The same screw 51 is sleeved within the two first bearings 53. The outer surface of the screw 51 is threadedly connected to the inner surfaces of the two nuts 52. The screw 51 and nuts 52 allow the rotation of the screw 51 to control the linear movement of the nuts 52. The outer surfaces of the two nuts 52 are fixedly connected to the interior of the two support plates 58 respectively. By setting the support plates 58, the support plates 58 can support and fix the clamping plate 59, preventing the clamping plate 59 from falling off. The opposite sides of the two support plates 58 are fixedly connected to one end of the two front piston structures 61 and the two rear piston structures 61 respectively. The top of the outer surface of the two support plates 58 is fixedly connected to the bottom of the outer surface of the two clamping plates 59 respectively. By setting the clamping plate 59, and the surface of the clamping plate 59 is provided with a rubber layer, the rubber layer can protect the cable when the clamping plate 59 clamps the cable, preventing cable wear.

[0040] like Figure 1 and Figure 3 As shown, four mounting holes 2 are provided on the outer surface of the mounting plate 1. The four mounting holes 2 are located at the four corners of the upper surface of the mounting plate 1. By setting the mounting holes 2, the position of the mounting plate 1 can be locked through the mounting holes 2 to ensure the stability of the mounting plate 1. The piston structure 61 includes a first piston 611, which is set inside the cylinder 67. By setting the first piston 611, the first piston 611 can ensure the sealing between the first piston 611 and the cylinder 67 and effectively prevent air leakage. One side of the outer surface of the first piston 611 is fixedly connected to one end of the movable rod 612. By setting the movable rod 612, the first piston 611 can be indirectly connected to the support plate 58. The other end of the movable rod 612 is fixedly connected to one side of the outer surface of the support plate 58.

[0041] like Figure 5As shown, the elastic structure 9 includes two rectangular sleeves 91 and a fixing plate 94. The top of the outer surface of the two rectangular sleeves 91 is fixedly connected to the bottom of the outer surface of the same fixing frame 55. The inner surfaces of the two rectangular sleeves 91 are slidably connected to the outer surfaces of the two rectangular plates 92, respectively. By setting the rectangular plates 92, the rectangular plates 92 can ensure the smooth sliding of the rectangular sleeves 91. Fixing blocks 95 are fixedly connected to the left and right sides of the outer surfaces of the two rectangular plates 92. By setting the fixing blocks 95, the fixing blocks 95 can fix the rectangular plates 92. The bottom of the outer surface of the four fixing blocks 95 is fixedly connected to the top of the outer surface of the mounting plate 1. The two sides of the outer surface of the fixing plate 94 are fixedly connected to one end of the two contact rods 4, respectively. By setting a fixing plate 94, the contact rod 4 can be fixed. The opposite faces of the two fixing blocks 95 on the left and the two fixing blocks 95 on the right are fixedly connected to the two sides of the two side plates 96 respectively. By setting the side plates 96, fixing points can be provided for the alarm 3 and the first switch 14. The alarm 3 is set on one side of the side plate 96, and the first switch 14 is set on the other side of the side plate 96. Two first springs 93 are sleeved on the outer surface of the rectangular plate 92. By setting the first springs 93, the elastic force of the first springs 93 can provide a certain resistance to external forces and reduce the drag of external forces on the cable. The two ends of the two first springs 93 are fixedly connected to the two sides of the rectangular sleeve 91 and one side of the two fixing blocks 95 respectively.

[0042] like Figure 6 , Figure 7 and Figure 8As shown, the two ends of the outer surface of the screw 51 are fixedly connected to the opposite faces of the two handles 54. The handles 54 allow the operator to easily control the rotation of the screw 51. The threads on both sides of the outer surface of the screw 51 are arranged in opposite directions, which facilitates the control of the two nuts 52 moving closer and further apart. The two sides of the inner wall of the fixing bracket 55 are fixedly connected to the two sides of the outer surface of the guide plate 56. The outer surface of the guide plate 56 is slidably connected to the inner surfaces of the two guide sleeves 57. The guide plate 56 and guide sleeves 57 allow the guide sleeves 57 to slide stably on the surface of the guide plate 56, thus enabling the support plate 58 to move stably. The two guide sleeves 57 are respectively engaged with the two... Inside the support plate 58, the overheat alarm structure 8 includes a second bearing 81. By setting the second bearing 81, the smooth rotation of the roller 82 can be ensured. By setting the roller 82, the friction between the roller 82 and the cable can be reduced, allowing the cable to slide smoothly. The second bearing 81 is fixedly connected to the top of the outer surface of the sleeve 10. The roller 82 is sleeved inside the second bearing 81. A shell 84 is fixedly connected inside the roller 82. Several through holes 86 are opened on the outer surface of the shell 84 to facilitate air intake. A piston rod 85 is set inside the shell 84. A second switch 83 is set on the upper side of the inner wall of the roller 82 to facilitate the operation of the alarm 3.

[0043] The method of using a cable positioning and locking device for wire-crushing transmission in building electromechanical installation includes the following steps:

[0044] S1. In use, first turn the handle 54, causing the handle 54 to drive the screw 51 to rotate. This causes the screw 51 to drive the two nuts 52 closer together, which in turn drives the two support plates 58 closer together. This causes the two support plates 58 to drive the two movable rods 612 to move. The two movable rods 612 then drive the first piston 611 to move inside the cylinder 67. Since the cylinder 67 and the cylindrical tube 62 contain liquid, the first piston 611 can press the liquid into the cylindrical tube 62, which in turn drives the second piston 63 to move. This causes the second piston 63 to drive the connecting rod 64 to move. 4. The connecting plate 65 is moved, which in turn moves the hole sleeve 10. At the same time, the connecting plate 65 pulls the rope 15, which moves the connecting block 18, causing the second spring 17 to deform. This causes the two hole sleeves 10 to separate, which in turn moves the support frame 13. The support frame 13 then moves the arc plate 12, causing the two arc plates 12 to move away from each other. Simultaneously, the hole sleeves 10 move the two rollers 82 away from each other. Because the gap between the two clamping plates 59 is large, they will not close. Even after the two arc plates 12 open, the gap between the clamping plates 59 can still ensure that the cable can be inserted smoothly.

[0045] S2. Then, place the cable between the two arc-shaped plates 12 from top to bottom, and rotate the handle 54 in the opposite direction. This causes the screw 51 to move the two nuts 52 away from each other, causing the two support plates 58 to move the movable rod 612 back to its original position. This causes the first piston 611 to return to its original position, causing the second piston 63 to push the connecting rod 64 to move. The connecting rod 64 then pushes the connecting plate 65 to move, causing the connecting plate 65 to loosen the cable 15. At this time, the elastic force of the second spring 17 pushes the connecting block 18 to move, and at the same time, the connecting plate 65 moves the hole sleeve 10. The hole sleeve 10 then moves the arc-shaped plate 12 through the support frame 13, causing the two... When the arc-shaped plates 12 close together, the two sleeves 10 drive the two rollers 82 to approach each other and adhere to the cable. At this time, the cable can be dragged to perform the cable transmission operation, so that the cable cleaning ring 11 can clean the surface of the cable. If the rollers 82 get stuck when the cable is dragged, the friction between the cable and the rollers 82 will increase, which will generate heat. Heat will be generated inside the rollers 82, and the internal gas will expand and enter the shell 84 through the through hole 86, causing the piston rod 85 to move upward. The piston rod 85 will then trigger the second switch 83. At this time, the second switch 83 can control the alarm 3 to perform the alarm operation, so as to promptly remind relevant personnel to handle the situation.

[0046] S3. After the cable transmission is completed, turn the handle 54 to drive the screw 51 to rotate, causing the two nuts 52 to move closer to each other, causing the two connecting plates 65 to move closer to each other, and causing the two clamping plates 59 to move closer to each other. This allows the two clamping plates 59 to clamp the cable. When the cable is clamped and subjected to external tension, the clamping plates 59 lock the cable, causing the cable to drag the clamping plates 59 and the support plate 58 to move. This causes the support plate 58 to drive the first bearing 53 and the fixing frame 55 to move through the nuts 52 and the screw 51, causing the rectangular sleeve 91 to slide. This causes the first spring 93 to deform, and at the same time, the contact rod 4 touches the first switch 14, causing the first switch 14 to control the alarm 3 to sound an alarm, so that relevant personnel can discover and deal with the situation in a timely manner.

[0047] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.

8. The cable positioning and locking device for building electromechanical installation with compressible cable transmission according to any one of claims 1-7, characterized in that, The method of using the cable positioning locking device includes the following steps: S1. In use, first turn the handle to rotate the screw, which in turn moves the two nuts closer together. This causes the two nuts to move the two support plates closer together, which in turn moves the two support plates to move the two movable rods. The two movable rods then move the first piston inside the cylinder. Since the cylinder and cylindrical tube contain liquid, the first piston can press the liquid into the cylindrical tube, which in turn moves the second piston. This moves the second piston, which in turn moves the connecting rod, which in turn moves the connecting plate, which in turn moves the hole sleeve. At the same time, the connecting plate pulls the rope, which moves the connecting block, causing the second spring to deform. This causes the two hole sleeves to separate, which in turn moves the support frame, which in turn moves the arc plate, causing the two arc plates to move away from each other. Simultaneously, the hole sleeves move the two rollers away from each other. Because the gap between the two clamping plates is large, they will not close. Even after the two arc plates open, the gap between the clamping plates still ensures that the cable can be inserted smoothly. S2. Then, place the cable between the two arc-shaped plates from top to bottom and rotate the handle in the opposite direction. This causes the screw to move the two nuts away from each other, allowing the two support plates to reset the movable rod, which in turn resets the first piston. The second piston then pushes the connecting rod to move, which in turn pushes the connecting plate to move, loosening the cable. At this point, the elastic force of the second spring pushes the connecting block to move, and the connecting plate moves the hole sleeve. The hole sleeve then moves the arc-shaped plate through the support frame, causing the two arc-shaped plates to close together. Simultaneously, the two hole sleeves move the two rollers closer together to fit the cable. Now, the cable can be dragged for cable transfer. The cable cleaning ring can clean the surface of the cable. If the roller gets stuck while the cable is being dragged, the friction between the cable and the roller increases, generating heat. This heat causes the internal gas to expand and enter the shell through the through hole, causing the piston rod to move upward and trigger the second switch. The second switch then controls the alarm to sound, allowing relevant personnel to be alerted in time. S3. After the cable transmission is completed, turn the handle to drive the screw to rotate, causing the two nuts to move closer to each other, the two connecting plates to move closer to each other, and the two clamping plates to move closer to each other. This allows the two clamping plates to clamp the cable. When the cable is clamped and subjected to external tension, the clamping plates lock the cable, causing the cable to drag the clamping plates and support plates to move. This causes the support plates to move the first bearing and the fixing frame through the nuts and screw, causing the rectangular sleeve to slide and the first spring to deform. At the same time, the contact rod touches the first switch, causing the first switch to control the alarm to sound, so that relevant personnel can discover and deal with the situation in a timely manner.
