Technical Field

[0001] The utility model belongs to the technical field of wire threading devices, and particularly relates to a wire threading device for municipal public works. Background Technique

[0002] A wire threading device is a device for threading wires through a wire pipe during the construction of municipal building electrical engineering. The commonly used wire threading device is to pre-thread a pulling rope into the wire pipe. After the construction is completed, one end of the wire is connected to the pulling rope, and by pulling the pulling rope, the wire is threaded into the interior of the wire pipe.

[0003] However, the commonly used pulling rope is a single-strand pulling rope. There are many high-power wires in municipal engineering, and high-power wires are relatively thick and hard. During the wire threading process, the pulling force on the pulling rope is relatively large. Once the pulling rope breaks, it is difficult to continue pulling the wire, resulting in the failure of wire threading. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire threading device for municipal public works. During the pulling process, when the stressed pulling rope breaks, the wire can be continuously pulled through the safety rope, improving the success rate of wire threading, so as to solve the problems raised in the above background technique.

[0020] In order to make the purpose and advantages of the utility model clearer, the following specifically describes the utility model with reference to the embodiments. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the specific protection scope claimed by the utility model.

[0021] As Figure 1 and 2As shown in the figure, a threading device for municipal public works includes a stress-bearing pulling rope 1 and a safety rope 2. A combined end 3 is fixedly connected to the stress-bearing pulling rope 1. There are several combined ends 3, and several combined ends 3 are equidistantly distributed along the length direction of the stress-bearing pulling rope 1. A connecting member 4 is fixedly connected to the combined end 3. The safety rope 2 passes through the connecting member 4 and is fixedly connected to the connecting member 4. One end of the stress-bearing pulling rope 1 is fixedly connected to a connecting end 5, and one end of the safety rope 2 is fixedly connected to the connecting end 5.

[0022] According to the above structure, when threading, connect the electric wire to the connecting end 5, and then pull the stress-bearing pulling rope 1 to thread the electric wire into the pipeline. The safety rope 2 plays an insurance role. During the pulling process, when the stress-bearing pulling rope 1 breaks, the electric wire can continue to be pulled through the safety rope 2, improving the success rate of threading.

[0023] As Figure 3 and 4 shown, the combined end 3 includes a tapered head 31 and a column head 32. The column head 32 is fixedly connected to one end of the tapered head 31. A C-shaped groove 33 is provided on the side wall of the column head 32.

[0024] According to the above structure, when threading, if there is sand blockage in the pipeline, the setting of the tapered head 31 is beneficial to dredge the pipeline and facilitate threading.

[0025] As Figure 3 and 4 shown, to improve the tensile strength of the stress-bearing pulling rope 1, the stress-bearing pulling rope 1 is arranged in a double strand. The stress-bearing pulling rope 1 passes through the tapered head 31 and the column head 32, and the stress-bearing pulling rope 1 is fixedly connected to the tapered head 31 and the column head 32. Equally spaced nodules 11 are provided on the stress-bearing pulling rope 1, and several nodules 11 are respectively arranged at one end of several column heads 32.

[0026] According to the above structure, the setting of the nodules 11 can improve the connection stability between the stress-bearing pulling rope 1 and the combined end 3. When pulling the stress-bearing pulling rope 1, the nodules 11 can abut against the end of the column head 32, preventing relative sliding between the stress-bearing pulling rope 1 and the column head 32.

[0027] As Figure 4 shown, the connecting member 4 includes a C-shaped sleeve 41 fixedly connected inside the C-shaped groove 33. An arc-shaped plate 42 is fixedly connected to the side wall of the C-shaped sleeve 41. The safety rope 2 passes through the arc-shaped plate 42 and is fixedly connected to the arc-shaped plate 42. The length of the stress-bearing pulling rope 1 between adjacent two column heads 32 is 2 - 3 centimeters shorter than the length of the safety rope 2 between adjacent two column heads 32.

[0028] According to the above structure, since the length of the stress-bearing pulling rope 1 between adjacent two column heads 32 is shorter than the length of the safety rope 2 between adjacent two column heads 32, when pulling the electric wire, the stress-bearing pulling rope 1 is stressed first. If the stress-bearing pulling rope 1 breaks, the safety rope 2 can be stressed to continue pulling the electric wire.

[0029] As Figure 5 shown, the connecting end 5 includes a connecting bar 51. One end of the stress-bearing pulling rope 1 and one end of the safety rope 2 are both fixedly connected to one side of the connecting bar 51. A ring 52 for connecting an electric wire is arranged on the other side of the connecting bar 51.

[0030] According to the above structure, connecting the electric wire to the ring 52 facilitates the connection between the electric wire and the device.

[0031] The working principle of the present utility model is as follows: Connect the electric wire to the ring 52. When threading the wire, pull the stress-bearing pulling rope 1 to thread the electric wire into the wire pipe. The safety rope 2 plays a safety role. During the pulling process, since the length of the stress-bearing pulling rope 1 between two adjacent column heads 32 is shorter than the length of the safety rope 2 between two adjacent column heads 32, when pulling the electric wire, the stress-bearing pulling rope 1 is stressed first. If the stress-bearing pulling rope 1 breaks, the safety rope 2 can be stressed to continue pulling the electric wire, improving the success rate of threading. When there is sand blockage in the wire pipe during threading, the setting of the conical head 31 is beneficial to dredge the wire pipe for easy threading. The setting of the knot 11 can improve the connection stability between the stress-bearing pulling rope 1 and the combined end 3. When pulling the stress-bearing pulling rope 1, the knot 11 can abut against the end of the column head 32 to prevent relative sliding between the stress-bearing pulling rope 1 and the column head 32.

[0032] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
