Description

TECHNICAL FIELD

[0001] The utility model discloses a wire pipe drawing device, is suitable for circuit installation uses. BACKGROUND

[0002] The most widely used in the circuit construction process is hidden installation type at present, that is, fixing PVC line pipe in the wall groove or ground groove opened in advance, covering with cement, and then covering wall paint, ceramic tile or floor on the surface. There are electric wires in the line pipe, and the electric wires are connected with each electric point. Such hidden line installation mode can achieve the purpose of beauty and order.

[0003] There are two ways of installing electric wires in line pipe. The earliest one is pre-installation, that is, when embedding line pipe, the electric wire is inserted into the line pipe, and then the subsequent covering process is carried out.

[0004] In order to facilitate future maintenance and replacement, the construction requires that the electric wire is made into a live wire process, that is, any electric wire can be pulled out of the line pipe and replaced. Therefore, the line pipe arrangement direction and the turning radius are required. The above-mentioned pre-installation type obviously cannot meet the requirements of the live wire process. In order to solve this problem, the pipe-through type has appeared in recent years, that is, only the empty line pipe is embedded, and then the electric wire is inserted into the line pipe after the surface process is completed. The successful threading of the electric wire means that the live wire process can be realized. The specific operation steps are as follows: the metal pipe-through line with toughness and strength is inserted into the line pipe opening, the pipe-through line is pushed out of the other end opening of the line pipe, then the electric wire on the line roll is hung on the hook of the pipe-through line, and then the pipe-through line with the electric wire is pulled back until the front end of the electric wire is pulled back to the line pipe opening, and the electric wire installation task of this section of line pipe is completed. In this way, the live wire process can be ensured to meet the standard, the future maintenance and replacement are facilitated, and the owner can also confirm that all the electric wires in the line pipe have no joints.

[0005] In addition, when a certain section of electric wire needs to be repaired and replaced individually after use, only the section of electric wire needs to be pulled out, and the new wire needs to be pulled in.

[0006] The above-mentioned two cases all need to carry out threading operation. The most original construction method is to pull by hand, and the disadvantages of this method are as follows: 1. laborious, high labor intensity and low efficiency, especially in the case of long distance and many turns. 2. When pulling, the front end of the pulling device or the electric wire and the rear end of the electric wire will rub against the wall surface or the bottom box because the direction of the force and the direction of the line pipe are perpendicular. This will cause damage to the wall surface, the bottom box and the electric wire on one hand, and a person needs to send the wire at the rear end on the other hand, so that single-person operation cannot be realized. 3. The line pipe on the top needs to be operated by ladder.

[0007] In order to solve the above problems, in recent years, some simple auxiliary devices also appear, the main structure is that the body is fixed on the bottom box through the spring or screw, the body is provided with a roller, the roller can realize that the wire does not contact the bottom box, and the friction damage condition is avoided, but only this, and other problems still have no better solution.

[0021] Figure 5 is a structural schematic of Example 2.

[0022] Figure 6 is a structural schematic of Example 3 DETAILED DESCRIPTION

[0023] Example 1:

[0024] 1 is a bracket, 2 is a vertical pole, 3 is a vertical pole, 4 is an upper horizontal pole, 5 is a middle horizontal pole, 6 is a lower horizontal pole, 7 is a roller, 8 is a roller, 9 is a reel, 10 is an extension frame, 11 is a roller, 12 is a horizontal support pole, 13 is an "L" shaped opening hole, 14 is a post, 15 is a baffle, 16 is a handle, 18 is a wire tube, 19 is a tube penetrating wire, 20 is an electric wire, and 21 is a bottom box.

[0025] Wall construction: as shown in Figure 1 , Figure 2 , Figure 3 , at the feeding end, the tube penetrating wire 19 is extended into the wire tube 18 according to the traditional method, and after being pushed to the rear end, the electric wire 20 is connected, and then the front end of the tube penetrating wire 19 is fixed on the reel 9. By exerting force on the handle 16 with the hand, the reel 9 and the lower horizontal pole 6 are rotated (the reel 9 is fixed on the lower horizontal pole 6, and the lower horizontal pole 6 and the vertical pole 2 and the vertical pole 3 have bearings therebetween), so that the tube penetrating wire 19 is pulled and wound on the reel 9 until the electric wire 20 is pulled out.

[0026] In the above process, after the tube penetrating wire 19 or the electric wire 20 comes out of the end of the wire tube 18 in the bottom box 21, it rubs on the rollers 11 and 8 and finally reaches the reel 9. The rollers 11 and 8 play the roles of following, reducing frictional resistance and bearing 90 degree turning force (the rollers 8 and 11 and the middle horizontal pole 5 and the extension frame 10 have bearings therebetween). In the whole process, the tube penetrating wire 19 or the electric wire 20 does not contact the bottom box 21 and the wall surface.

[0027] The function of the extension frame 10 is to make the roller 11 extend into the bottom box 21 as far as possible and approach the opening of the wire tube 18, as shown in Figure 2 , so that the friction between the opening of the wire tube 18 and the tube penetrating wire 19 or the electric wire 20 can be effectively reduced.

[0028] The height of the middle horizontal pole 5 is adjusted according to the height of the bottom box 21, and the adjustment is achieved by putting the posts 14 at both ends of the middle horizontal pole 5 into the "L" shaped opening holes 13. The posts 14 here are square posts, which are used to avoid the rotation of the middle horizontal pole 5 as a whole, so that the position of the extension frame 10 is changed.

[0029] The transverse support rod 12 is in contact with the wall surface and bears the transverse thrust.

[0030] At the feeding end, as shown in Figure 4 , the rear end of the wire 20 is wound on the wire reel 9, and the wire 20 enters the opening of the wire tube 18 from bottom to top through the rollers 8 and 11 under the action of the pulling force at the pulling end. Thus, the wire 20 is continuously pulled without being jammed or damaged, and the feeding end can be unattended, realizing single-person operation of the whole process.

[0031] Embodiment 2

[0032] Ceiling construction: as shown in Figure 5 , the basic action mode is similar to that of embodiment 1, except that the height of the upper cross rod 4 is adjusted, the wire 19 or the wire 20 is threaded, and after coming out of the end of the wire tube 18 on the ceiling, it is wiped on the roller 7 and then turned to reach the wire reel 9.

[0033] At this time, the columns 14 at both ends of the upper cross rod 4 are round columns, and the roller 7 and the upper cross rod 4 can be in a fixed connection relationship, i.e., the upper cross rod 4 and the roller 7 rotate synchronously.

[0034] Embodiment 3

[0035] As shown in Figure 6 , in order to achieve the effect of saving labor, the motor 17 and the gear set 22 are used to drive the lower cross rod 6, thereby driving the wire reel 9 to rotate.
