[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a conduit threader for power construction, comprising a support plate 1, a winding wheel assembly 3 fixedly installed above the support plate 1, a fixed pole 2 fixedly installed above the support plate 1 and on one side of the winding wheel assembly 3, a support assembly 6 fixedly installed above the support plate 1 and on the side of the fixed pole 2 away from the winding wheel assembly 3, a plurality of universal wheels 7 with brakes fixedly installed below the support plate 1, a protective cleaning device 4 installed above the support plate 1 and on the outside of the winding wheel assembly 3, and a cutting device 5 installed above the support plate 1 and between the fixed pole 2 and the support assembly 6.

[0022] Specifically, the protective cleaning device 4 includes a fixed box 41, a lead screw 42, a lifting block 43, a cleaning component 44, and a protective shell 45. The fixed box 41 is fixedly installed above the support plate 1 and on the side of the winding wheel assembly 3 away from the fixed rod 2. The lead screw 42 is installed near the center of the fixed box 41 via a bearing. The lifting block 43 is installed on the outside of the lead screw 42 and on the inside of the fixed box 41 via a thread. The protective shell 45 is fixedly installed on one side of the lifting block 43 and on the outside of the winding wheel assembly 3. The cleaning component 44 is fixedly installed on the side of the protective shell 45 near the fixed rod 2.

[0023] By adopting the above technical solution, staff can protect the winding wheel assembly 3 and the wires on it by using the cooperation of the lead screw 42 and the protective shell 45 when needed, thereby reducing the possibility of accidental damage to the wires.

[0024] Specifically, the shape and size of the inner cross-section of the fixed box 41 are the same as the shape and size of the outer cross-section of the lifting block 43.

[0025] By adopting the above technical solution, the threader can ensure that the inner side of the fixing box 41 and the outer side of the lifting block 43 fit together, thereby preventing the lifting block 43 from shifting during the lifting process and ensuring the normal operation of the work.

[0026] Specifically, the cleaning component 44 includes a fixed cylinder 441, a cleaning brush 442, and a screw 443. The fixed cylinder 441 is fixedly installed on the side of the protective shell 45 near the fixed pole 2. The top and bottom of the fixed cylinder 441 are threaded with screws 443. The two adjacent sides of the two screws 443 are fitted with cleaning brushes 442 via bearings.

[0027] By adopting the above technical solution, workers can clean the surface of the wires when needed by using the screw 443 and cleaning brush 442, thereby better meeting the work needs in different situations.

[0028] In this embodiment, when a conduit puller is needed for electrical construction, the worker first places the wire on the winding wheel assembly 3, then rotates the lead screw 42 in the protective cleaning device 4. The lead screw 42 is threadedly connected to the lifting block 43, and the outer side of the lifting block 43 is in contact with the inner side of the fixing box 41. Therefore, the lead screw 42 drives the lifting block 43 and its protective shell 45 to descend until the protective shell 45 covers the winding wheel assembly 3 and the wire on it. Then, the worker pushes the puller, and the puller is moved to the working position by the various braked casters 7 under the support plate 1. Place the wire through the fixed cylinder 441 in the cleaning assembly 44. The operator can rotate the two screws 443 respectively. The screws 443 are connected to the cleaning brushes 442 by bearings. The front and rear sides of the cleaning brushes 442 are in contact with the inner side of the fixed cylinder 441. Therefore, the two screws 443 drive the two cleaning brushes 442 to move until the two cleaning brushes 442 are in close contact with the wire. When the wire moves, the two cleaning brushes 442 can wipe away the dirt on the wire. Then, the wire is passed through the fixed rod 2 and the support assembly 6, and finally enters the required pipe for use.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the cutting device 5 includes a fixed frame 51, a cutter 52, a pressing plate 54, and a connecting rod 55. The fixed frame 51 is fixedly installed above the support plate 1 and between the fixed rod 2 and the support assembly 6. The connecting rod 55 is slidably connected to the top of the fixed frame 51. The cutter 52 is fixedly connected to the bottom of the connecting rod 55 and inside the fixed frame 51. The pressing plate 54 is fixedly connected to the top of the connecting rod 55.

[0031] By adopting the above technical solution, workers can cut the wires when needed through the cooperation of structures such as the fixed frame 51 and the cutter 52, thereby reducing the inconvenience that may be encountered during the work process and better meeting the needs of the work.

[0032] Specifically, the cutting device 5 also includes a compression spring 53, which is fixedly connected between the fixed frame 51 and the pressing plate 54 and located outside the connecting rod 55.

[0033] By adopting the above technical solution, after the wire is cut, the pressing plate 54 and the cutter 52 can return to their original positions by compressing the spring 53, thereby reducing the possibility of adverse effects on subsequent work and ensuring the normal operation of the work.

[0034] In this embodiment, during operation, the operator can pass the wire through the inner side of the fixed frame 51 in the cutting device 5. When the wire needs to be cut, the operator presses the pressing plate 54, which in turn drives the cutter 52 to descend via the connecting rod 55, thereby cutting the wire. This reduces the inconvenience for the operator. After the cutting is completed, the operator releases the pressing plate 54. Under the action of the compression spring 53, the pressing plate 54 rises, which in turn drives the connecting rod 55 and the cutter 52 back to their original positions. The inner side of the fixed frame 51 and the front and rear sides of the cutter 52 are in contact with each other.

[0035] The structure and principle of the support plate 1, fixed rod 2, winding wheel assembly 3 (composed of fixed plate, connecting plate, support plate, connecting component, motor and winding wheel), support component 6, and braked universal wheel 7 in this utility model have been disclosed in a power construction conduit cable puller disclosed in Chinese patent application number 202421102253.5. Its working principle is as follows: during use, the two plugs on the connecting component are inserted and connected to the connecting plate, and the plate body is sleeved with the bearing on the winding wheel. The position of the connecting component is then positioned by screws to support the rotation of the winding wheel. The connection, installation, and disassembly of the connecting component and the connecting plate are convenient, facilitating the replacement of the winding wheel and improving flexibility. Four braked universal wheels move the entire power construction conduit cable puller to the cable pulling area. The height of the adjusting component is adjusted by sliding and by limiting screws, thereby adjusting and fixing the height of the three support rods. This ensures that the wire is flush with the conduit opening during cable pulling, preventing the wire from forming an angle with the conduit opening and causing wear, thus improving stability.

[0036] The working principle and usage process of this utility model are as follows: When a conduit threader is needed for power construction, the worker first places the wire on the winding wheel assembly 3, and then rotates the screw 42 in the protective cleaning device 4. The screw 42 is threadedly connected to the lifting block 43, and the outer side of the lifting block 43 is in contact with the inner side of the fixed box 41. Therefore, the screw 42 drives the lifting block 43 and its protective shell 45 to descend until the protective shell 45 covers the winding wheel assembly 3 and the wire on it. Then, the worker pushes the threader, and moves it to the working position through the various braked casters 7 under the support plate 1. Then, the wire is passed through the fixed cylinder 441 in the cleaning assembly 44. The worker can rotate the two screws 443 respectively. The screws 443 are connected to the cleaning brush 442 by bearings, and the front and rear sides of the cleaning brush 442 are in contact with the inner side of the fixed cylinder 441. The two screws 443 respectively drive the two cleaning brushes 442 to move until the two cleaning brushes 442 are in close contact with the wire. When the wire moves, the two cleaning brushes 442 can wipe away the dirt on the wire, and then let the wire pass through the fixed rod 2 and the support assembly 6, and finally enter the required pipe for use. During operation, the operator can let the wire pass through the inside of the fixed frame 51 in the cutting device 5, and then press the pressing plate 54 when the wire needs to be cut, so that the cutter 52 is driven down through the connecting rod 55 to cut the wire, reducing the inconvenience of the operator. After the cutting is completed, the pressing plate 54 is released, and the pressing plate 54 rises under the action of the compression spring 53, which in turn drives the connecting rod 55 and the cutter 52 back to their original positions, and the inside of the fixed frame 51 is in close contact with the front and rear sides of the cutter 52.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
