Description

Technical Field

[0001] This utility model relates to the field of construction wiring technology, specifically a wiring device for building engineering. Background Technology

[0002] Wiring installation in building construction refers to the process of passing wires or cables through pre-laid conduits, cable trays, or cable racks during the electrical installation of a building. Construction workers must arrange, pull, and fix the wires and cables reasonably according to design requirements to ensure that the wiring connections are correct, neat, and orderly, while also ensuring that the wires and cables are not damaged, so as to achieve the normal operation of electrical functions such as power supply and signal transmission within the building, and to comply with relevant electrical installation specifications and safety standards.

[0003] According to the announcement number CN119297853A, a wiring construction device for building engineering includes a movable base, a wiring box, and a shock-absorbing groove. The wiring box is located on the upper side of the movable base, and the shock-absorbing groove is opened on the left and right sides of the bottom of the movable base. A lifting box is fixedly connected to the top of the movable base, and a first motor is fixedly connected to the right side of the rear side wall of the lifting box.

[0004] This wiring device for building construction can move the first guide roller during wiring, allowing the first and second guide rollers to clamp the wire body. However, the device is difficult to adjust the clamping force on the wires and cables flexibly. After the cables have been used for a period of time, there may be difficulties in pulling or slippage during the cable pulling process. It may also cause the cable to not be tightly wound when winding and unwinding. Therefore, the device needs to be improved accordingly. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wiring construction device for building engineering, comprising a base, a deceleration mechanism fixedly connected to the top of the base, and a clamping mechanism provided at the left end of the top of the base;

[0007] The clamping mechanism includes a support base located at the top left end of the base. Two bidirectional lead screws are rotatably connected to the front and rear ends of the support base. A cross-threaded block is threaded onto the surface of each bidirectional lead screw. A guide seat is fixedly connected to the surface of each cross-threaded block. A first spring is fixedly connected inside the guide seat. An I-shaped block is fixedly connected to one end of the first spring. A long rod is rotatably connected to the surface of the first spring.

[0008] Preferably, the guide seat has a vertical groove inside, and the surface of the I-shaped block is slidably connected to the inside of the vertical groove, so that the I-shaped block can slide inside the vertical groove.

[0009] Preferably, the support base has slots on its front and rear interiors, and the surface of the cross-threaded block is slidably connected to the interior of the slots.

[0010] Preferably, a groove is formed inside the left end of the support base, and the surface of the slider is slidably connected to the inside of the groove, so as to facilitate the slider to slide inside the groove.

[0011] Preferably, the deceleration mechanism includes a T-shaped platform, which is fixedly connected to the top of the base. The left end of the T-shaped platform is fixedly connected to the right side of the support seat. A crossbar is rotatably connected inside the T-shaped platform. A take-up roller is fixedly connected to the surface of the crossbar. A friction cylinder is fixedly connected to the left end of the take-up roller.

[0014] Compared with the prior art, this utility model provides a wiring construction device for building engineering, which has the following beneficial effects:

[0015] 1. This cable threading device for construction engineering, through a clamping mechanism, uses a first clamping roller to drive an I-shaped block to clamp the surface of the cable during the threading process, and a second clamping roller to drive a slider to clamp the cable during the second spring. This allows for control of the tension force on the surface of the take-up roller during cable threading and unwinding, preventing difficulties in pulling or slippage during cable pulling, and also preventing the cable from becoming loose on the surface of the take-up roller. In addition, rotating the bidirectional screw drives the cross-threaded block to slide inside the support seat, thereby driving the guide seat to move up and down for adjustment. This changes the gap of the first clamping roller and thus changes the control of the clamping force on the cable, further facilitating the cable threading and unwinding operation.

[0016] 2. This cable-threading device for construction projects, through a deceleration mechanism, rotates a bidirectional screw to drive a cross-threaded block to slide inside a support base, thereby adjusting the guide seat up and down. This changes the gap of the first clamping roller and thus alters the control of the cable winding and unwinding clamping force. Additionally, rotating an adjusting screw moves a T-shaped block inside a T-shaped seat, causing the connecting strip and friction cylinder to move under the limit of the limiting rod. This changes the contact area between the friction cylinder and the friction cylinder, thereby altering the frictional force between them and changing the force required for cable pulling, thus preventing difficulties in cable pulling.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Combination Figures 2 to 7 A wiring construction device for building engineering includes a base 1, a deceleration mechanism 3 fixedly connected to the top of the base 1, and a clamping mechanism 2 provided at the top left end of the base 1.

[0031] The clamping mechanism 2 includes a support base 21, which is located at the top left end of the base 1. A bidirectional lead screw 22 is rotatably connected to the front and rear ends of the support base 21. A cross-threaded block 23 is threaded onto the surface of the bidirectional lead screw 22. A guide seat 242 is fixedly connected to the surface of the cross-threaded block 23. A first spring 241 is fixedly connected inside the guide seat 242. An I-shaped block 24 is fixedly connected to one end of the first spring 241, and a long rod 25 is rotatably connected to its surface. A first clamping roller 26 is fixedly connected to the surface of the long rod 25. A transmission wheel 261 is fixedly connected to the upper surface of the rod 22, and a transmission belt 262 is connected to the surface of the transmission wheel 261. A second spring 27 is fixedly connected inside the support base 21. A slider 28 is fixedly connected to one end of the second spring 27. There are two sets of sliders 28. A second clamping roller 29 is rotatably connected between the two sets of sliders 28. A vertical groove is opened inside the guide seat 242. The surface of the I-shaped block 24 is slidably connected to the inside of the vertical groove. The front and rear interiors of the support base 21 are respectively opened with slots. The surface of the cross-threaded block 23 is slidably connected to the inside of the slot.

[0032] Furthermore, a groove is opened inside the left end of the support base 21, and the surface of the slider 28 is slidably connected to the inside of the groove. The first clamping roller 26 uses the elastic force of the first spring 241 to drive the I-shaped block 24 to perform clamping force on the surface of the cable under the limiting action inside the guide seat 242. On the other hand, the second clamping roller 29 uses the elastic force of the second spring 27 to make the slider 28 perform corresponding clamping on the cable under the limiting action inside the support base 21. In this way, the tension of the cable wound on the surface of the take-up roller 33 can be controlled during the cable threading and unwinding, so as to avoid the phenomenon of the cable slack on the surface of the take-up roller 33.

[0033] Example 2

[0034] See Figure 1-7 Furthermore, based on Embodiment 1, the deceleration mechanism 3 includes a T-shaped platform 31, which is fixedly connected to the top of the base 1. The left end of the T-shaped platform 31 is fixedly connected to the right side of the support base 21. A crossbar 32 is rotatably connected inside the T-shaped platform 31. A take-up roller 33 is fixedly connected to the surface of the crossbar 32. A friction cylinder 34 is fixedly connected to the left end of the take-up roller 33. A T-shaped seat 35 is fixedly connected to the bottom front end of the T-shaped platform 31. An adjusting screw 36 is rotatably connected inside the T-shaped seat 35. A T-shaped block 37 is threadedly connected to the surface of the adjusting screw 36. A connecting strip 38 is fixedly connected to the top of the T-shaped block 37. A friction cylinder 39 is fixedly connected to the top of the connecting strip 38. A limiting rod 391 is fixedly connected to the front of the T-shaped platform 31. A limiting hole is opened inside the friction cylinder 39. The surface of the limiting rod 391 is slidably connected to the limiting hole.

[0035] Furthermore, a guide groove is provided inside the T-shaped seat 35, and the surface of the T-shaped block 37 is slidably connected to the inside of the guide groove. By rotating the adjusting screw 36, the T-shaped block 37 is moved inside the T-shaped seat 35, which in turn causes the connecting strip 38 and the friction cylinder 39 to move under the limit of the limiting rod 391. This changes the tight contact area between the friction cylinder 34 and the friction cylinder 39, thereby changing the frictional force between the friction cylinder 34 and the friction cylinder 39, and thus changing the force required when pulling the cable, avoiding difficulties in pulling the cable.

[0036] In actual operation, when this device is used for wire threading in construction projects, the cable wound on the take-up roller 33 is pulled out and sequentially passed between the two first clamping rollers 26 and the two second clamping rollers 29. Then, grooves are opened in the middle of the surfaces of both the first clamping rollers 26 and the second clamping rollers 29 for pulling and threading. The first clamping rollers 26 and the second clamping rollers 29 are relatively perpendicular to each other, ensuring that the cable is pulled from the center point, thus ensuring stable wire threading. During this process, the first clamping rollers... The roller 26 uses the elastic force of the first spring 241 to drive the I-shaped block 24 to perform clamping force on the surface of the cable under the limiting action inside the guide seat 242. On the other hand, the second clamping roller 29 uses the elastic force of the second spring 27 to allow the slider 28 to perform corresponding clamping on the cable under the limiting action inside the support seat 21. In this way, the tension of the cable wound on the surface of the take-up roller 33 can be controlled during the cable threading and unwinding, so as to avoid the phenomenon of the cable slack on the surface of the take-up roller 33.

[0037] Furthermore, during cable winding and unwinding, the rotation of the take-up roller 33 causes the friction cylinder 34 to fit tightly against the inner wall of the friction cylinder 39. This allows for friction between the friction cylinder 34 and the friction cylinder 39 during the rotation of the take-up roller 33, preventing the cable from becoming loosely entangled due to uncontrolled rotation of the take-up roller 33. Additionally, when the cable becomes difficult to pull, the clamping force of the cable and the frictional force between the friction cylinder 34 and the friction cylinder 39 can be adjusted. Rotating the bidirectional lead screw 22 causes the cross-threaded block 23 to slide inside the support seat 21, thereby driving the guide... The seat 242 can be adjusted up and down to change the gap of the first clamping roller 26 and thus change the control of the cable winding and unwinding clamping force. In addition, by rotating the adjusting screw 36, the T-shaped block 37 can be moved inside the T-shaped seat 35, and the connecting strip 38 and friction cylinder 39 can be moved under the limit of the limiting rod 391. This can change the tight contact area between the friction cylinder 34 and the friction cylinder 39, thereby changing the friction force between the friction cylinder 34 and the friction cylinder 39, and thus changing the force required when pulling the cable, avoiding difficulties in pulling the cable.
