Description

Technical Field

[0001] This utility model relates to the field of fire protection construction technology, and in particular to a wiring device for fire protection construction. Background Technology

[0002] The installation of fire protection equipment is a major part of fire protection construction. This includes the installation of automatic fire alarm and linkage systems, gas extinguishing systems, and smoke extraction and ventilation / air conditioning systems. The installation of automatic fire alarm and linkage systems involves laying numerous electrical wires between various components, often using concealed wiring methods such as embedding wires in conduits within walls. Current technology for this wiring often involves manual wire feeding, repeatedly loosening the wire reel before inserting one end of the conductor into the embedded conduit. This method is not only complex but also prone to causing wire tangling. Furthermore, workers need to hold the reel up for extended periods, leading to high labor intensity and reduced construction efficiency.

[0003] In the prior art, Chinese patent application number 202220556209.6 discloses a wire-threading device for fire protection construction, including a fixed base with handles and a vertical rod at both ends, a bearing plate at the end of the vertical rod, and a wire guide wheel rotatably connected to the fixed base for guiding the wire. The wire guide wheel is hollow and has an air inlet hole on its groove sidewall. A negative pressure mechanism communicating with the hollow part of the wheel is provided on the outer wall of the wire guide wheel. A wire-threading mechanism is provided on the bearing plate. This utility model has a simple structure, can effectively pull and feed the wire, improve the efficiency of wire threading, and prevent wire tangling during the feeding process.

[0004] However, the above-mentioned technical solutions have the drawback that although they use a motor to drive a pulley, belt, and driven pulley to make a pair of pressure rollers rotate and squeeze the wire into the pre-embedded pipe to complete the wire threading work, the distance between the pair of pressure rollers cannot be changed, which makes it impossible to thread wires of different thicknesses, resulting in a single function. Therefore, this application proposes a wire threading device for fire protection construction to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example

[0028] Reference Figures 1-4 A wiring device for fire protection construction includes a frame 1, and the wiring device further includes:

[0029] Two electric push rods 2 are provided, and the two electric push rods 2 are respectively fixedly installed on the left and right sides of the frame 1;

[0030] The bracket 3 is provided in two parts, both of which are located inside the frame 1. The two brackets 3 are fixedly mounted on the output shafts of the two electric push rods 2 on the sides of the two brackets that are far apart from each other.

[0031] The transmission assembly includes two sliders 4, two first motors 5, and two conveying rollers 6. The two sliders 4 are slidably connected to the bottom inner wall of the frame 1. A sliding hole 11 is provided on the top inner wall of the frame 1. The top ends of the two first motors 5 pass through the sliding hole 11 and are slidably connected to the sliding hole 11. The top end of the conveying roller 6 is fixedly installed on the output shaft of the corresponding first motor 5. The bottom end of the conveying roller 6 is rotatably connected to the top end of the corresponding slider 4. The top and bottom ends of the bracket 3 are fixedly installed to the first motor 5 and slider 4 located on the same side, respectively.

[0032] A support component is disposed below the frame 1 and is used to adjust the height of the frame 1.

[0033] To solve the problem of inapplicability to the transmission of cables of different thicknesses, such as Figure 2 As shown, by passing the cable through the interior of the frame 1 and placing it between the two conveying rollers 6, activating the two electric push rods 2 can drive the two supports 3 to move closer together. The two supports 3 can then drive the two sliders 4, the two first motors 5, and the two conveying rollers 6 to move closer together. The two conveying rollers 6 can then compress the cable. Activating the two first motors 5 can then drive the two conveying rollers 6 to rotate relative to each other. The two rotating conveying rollers 6 can then drive the cable to move, thereby realizing the cable feeding operation. In this way, stable feeding of cables of different thicknesses can be achieved, improving the applicability.

[0034] In order to provide stable sliding support for the first motor 5, limit blocks 10 are fixedly installed on the front and rear sides of both first motors 5, and one side of the limit block 10 is slidably connected to the inner wall of the sliding hole 11.

[0035] In order to provide stable sliding support for the slider 4, a groove 9 is provided on the bottom inner wall of the frame 1, and the two sliders 4 are slidably connected in the groove 9.

[0036] In order to improve the contact friction between the conveyor roller 6 and the cable and ensure the stability of the cable delivery, a rubber ring 7 is fixedly sleeved on the conveyor roller 6, and multiple rubber blocks 8 are fixedly installed at equal intervals on the outer side of the rubber ring 7.

[0037] In order to provide stable guidance and support for the cable, fixing plates 12 are fixedly installed on the front and rear sides of the frame 1, and wire conduits 13 are fixedly installed on both fixing plates 12.

[0038] To improve the adjustment of the cable feeding height, the base plate 14 is placed in an appropriate position and fixed to the ground. Then, the second motor 16 is activated, driving the lead screw 17 to rotate. Through the threaded connection between the lead screw 17 and the moving plate 18, the moving plate 18 and four transmission rods 19 can move up and down, thus adjusting the height of the frame 1. This allows for adjustment of the cable threading position at different heights, improving its applicability. The support assembly includes the base plate 14, the lifting frame 15, and the second motor 16. The system includes a lead screw 17, a movable plate 18, and four transmission rods 19. The top of the base plate 14 is fixedly installed at the bottom end of the lifting frame 15. The second motor 16 is fixedly installed at the top of the base plate 14. The bottom end of the lead screw 17 is fixedly installed on the output shaft of the second motor 16. The top end of the lead screw 17 is rotatably connected to the top inner wall of the lifting frame 15. The movable plate 18 is threaded onto the lead screw 17. The bottom ends of the four transmission rods 19 are all fixedly installed at the top of the movable plate 18. The top ends of the four transmission rods 19 all penetrate the top inner wall of the lifting frame 15 and are fixedly installed at the bottom of the frame 1.

[0039] To assist the frame 1 in its upward movement, a spring 20 is fixedly installed on the top of the lifting frame 15, and the top of the spring 20 is fixedly installed on the bottom of the frame 1.

[0040] It should be noted that the specific models of electric actuator 2, first motor 5, and second motor 16 used can be selected by those skilled in the art. Furthermore, the electric actuator 2, first motor 5, and second motor 16 mentioned above are all existing technologies, and this solution will not elaborate on them.

[0041] The working principle of this utility model is as follows: In use, firstly, the electric push rod 2, the first motor 5, and the second motor 16 are connected to an external power source. Then, by passing the cable through the inside of the frame 1 and positioning it between the two conveying rollers 6, activating the two electric push rods 2 causes the two supports 3 to move closer together. The two supports 3 then cause the two sliders 4, the two first motors 5, and the two conveying rollers 6 to move closer together. The two conveying rollers 6 then compress the cable. Activating the two first motors 5 then causes the two conveying rollers 6 to rotate relative to each other. The two rotating conveying rollers 6 then move the cable, thus enabling the cable feeding operation. This method can stably transport cables of different thicknesses, improving the applicability. In addition, by placing the base plate 14 in an appropriate position and fixing it to the ground, activating the second motor 16 causes the lead screw 17 to rotate. Through the threaded connection between the lead screw 17 and the moving plate 18, the moving plate 18 and the four transmission rods 19 can move up and down, thus adjusting the height of the frame 1. This allows for adjustment of the cable threading position at different heights, further improving the applicability.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
