[0002] In recent years, the number of newly built and renovated 10kV power supply lines has increased year by year. During the construction process of 10kV lines, a capstan traction conductor is required to complete the wiring work. The existing technical equipment of some construction units can no longer meet the increasing engineering needs, so they need to be improved, such as overhead line winding traction machines.

[0003] After searching, the patent application number CN202120619590.1 provides a 10kV overhead line automatic winding traction machine. The 10kV overhead line automatic winding traction machine includes a base, a capstan installed on the base, and a rope collector installed on the base. The end of the drum of the capstan is coaxially provided with a driving sprocket; the rope collector includes a bracket, a rotating shaft, a rope collecting disc and a driven sprocket. Brackets are installed at intervals on the base, and rotating shafts are rotatably arranged between the brackets. Rope collecting discs are arranged at intervals on the rotating shaft, and a driven sprocket is arranged at one end of the rotating shaft. A chain is arranged between the driven sprocket and the driving sprocket. The rope collector is driven to rotate by the chain, and the traction rope wound on the rope collector pulls the wire to move under the rotation of the rope collector, which saves manpower time for winding the traction rope and saves space for winding the traction rope. It has low price, simple operation, low construction cost, is easy to move in places with complex terrain, and can pull wires within the permitted range of construction.

[0004] Based on the above search and in combination with the prior art, it is found that in the prior art, the automatic winding traction machine for overhead wires similar to the above disclosure mostly requires manual observation of whether the cable is obstructed at all times when traction is being performed, so as to manually stop traction. However, in actual application, it is difficult for the operator to detect and stop traction in time, resulting in the cable being damaged by excessive traction. Therefore, an automatic winding traction machine for overhead wires is proposed to improve the above problem. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: an automatic winding traction machine for overhead lines, comprising a base, a take-up drum is installed on the upper end of the base through a take-up frame, a driving mechanism for driving the take-up drum to rotate, and a controller for controlling the start and stop of the driving mechanism are also installed on the upper end of the base:

[0007] A transmission shaft sleeve is installed at the side end of the take-up frame for horizontal rotation, and a transmission disc is fixed at one end of the transmission shaft sleeve close to the take-up disc. The connecting shaft of the take-up disc movably passes through the transmission disc and extends to the inner side of the transmission shaft sleeve, and a bearing is installed between the transmission shaft sleeve and the transmission shaft sleeve;

[0008] A first electromagnet is fixed on the end surface of the transmission disk close to the take-up disk, and a second electromagnet is fixed on the end surface of the take-up disk close to the transmission disk. The first electromagnet and the second electromagnet attract each other when powered on.

[0009] The driving mechanism is connected with the transmission shaft sleeve.

[0010] As a further supplement to the present solution, an elastic paddle is fixed to the end surface of the take-up drum close to the transmission disk, and a lever is fixed to the side end of the transmission disk. When the lever rotates with the transmission disk, the lever contacts the elastic paddle.

[0011] As a further supplement to this solution, the driving mechanism includes a power unit, a drive pulley and a drive belt;

[0012] The power unit is installed at the upper end of the base, and two transmission pulleys are provided, one transmission pulley is coaxially fixed on the output shaft of the power unit, and the other transmission pulley is coaxially fixed with the transmission shaft sleeve;

[0013] The transmission belt is connected between two transmission pulleys.

[0014] As a further supplement to this solution, a push handle is installed at one end of the base, and a moving wheel is installed at the bottom end of the base.

[0015] As a further supplement to the present solution, the push handle is rotatably connected to the base, and a fixed knob for fixing the push handle in an outwardly opened state is installed on the base.

In the utility model, through the coordinated arrangement of the transmission disk, the first electromagnet on the transmission disk, and the second electromagnet on the take-up drum, the first electromagnet and the second electromagnet can be energized when in use, and the two attract each other at this time. When the driving mechanism drives the transmission disk to rotate, the transmission disk rotates synchronously with the take-up drum through the action of the first electromagnet and the second electromagnet, and the traction rope is wound, so that the cable is pulled by the traction rope; when the cable is subjected to greater external resistance, the winding resistance of the take-up drum becomes larger accordingly. When the resistance is greater than the suction force between the first electromagnet and the second electromagnet, the first electromagnet is separated from the second electromagnet, and the transmission disk still rotates under the action of the driving mechanism, while the take-up drum does not rotate, thereby effectively preventing the cable from being damaged by excessive force.

[0019] 2. In the utility model, an elastic paddle is fixed on the end face of the take-up disk close to the transmission disk, and a lever is fixed on the side end of the transmission disk. When the lever rotates with the transmission disk, the lever contacts the elastic paddle and makes a clicking sound, so as to remind the staff to clear the obstacles in time.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: Reference Figure 1-6 The automatic winding traction machine for overhead lines shown includes a base 1, a take-up drum 3 is installed on the upper end of the base 1 through a take-up frame 2, a driving mechanism for driving the take-up drum 3 to rotate, and a controller 5 for controlling the start and stop of the driving mechanism are also installed on the upper end of the base 1. The driving mechanism includes a power unit 4, a transmission pulley 6 and a transmission belt 7. The power unit 4 is installed on the upper end of the base 1. The power unit 4 can adopt conventional power equipment in the prior art, such as an electric motor. The motor and the controller 8 are electrically connected using the prior art to control the start and stop of the motor.

[0030] A transmission sleeve 13 is installed on the side end of the take-up frame 2 for horizontal rotation, and a transmission disk 12 is fixed to one end of the transmission sleeve 13 close to the take-up drum 3. The connecting shaft of the take-up drum 3 movably passes through the transmission disk 12 and extends to the inner side of the transmission sleeve 13, and a bearing is installed between the transmission sleeve 13. A first electromagnet 14 is fixed to the end surface of the transmission disk 12 close to the take-up drum 3, and a second electromagnet 15 is fixed to the end surface of the take-up drum 3 close to the transmission disk 12. The first electromagnet 14 and the second electromagnet 15 attract each other when energized.

[0031] Two transmission pulleys 6 are provided, one transmission pulley 6 is coaxially fixed on the output shaft of the power unit 4 , and the other transmission pulley 6 is coaxially fixed to the transmission sleeve 13 , and the transmission belt 7 is connected between the two transmission pulleys 6 .

[0032] By the coordinated arrangement of the transmission disk 12, the first electromagnet 14 on the transmission disk 12, and the second electromagnet 15 on the take-up drum 3, the first electromagnet 14 and the second electromagnet 15 can be energized during use, and the two attract each other at this time. When the driving mechanism drives the transmission disk 12 to rotate, the transmission disk 12 rotates synchronously with the take-up drum 3 through the action of the first electromagnet 14 and the second electromagnet 15, and the traction rope is wound, thereby using the traction rope to pull the cable; when the cable is subjected to greater external resistance, the winding resistance of the take-up drum 3 becomes larger accordingly. When the resistance is greater than the suction force between the first electromagnet 14 and the second electromagnet 15, the first electromagnet 14 and the second electromagnet 15 are separated, and the transmission disk 12 still rotates under the action of the driving mechanism, while the take-up drum 3 does not rotate, thereby effectively preventing the cable from being damaged by excessive force.

[0033] Among them, in order to remind the staff of the obstruction of the cable, an elastic paddle 16 is fixed to the end face of the take-up reel 3 close to the transmission disc 12, and a lever 17 is fixed to the side end of the transmission disc 12. When the lever 17 rotates with the transmission disc 12, the lever 17 contacts with the elastic paddle 16, making a clicking sound, so as to remind the staff to clear the obstacle in time.

[0034] A push handle 8 is installed at one end of the base 1, and a moving wheel 10 is installed at the bottom end of the base 1 to facilitate the movement of the tractor.

[0035] like Figure 3 As shown, the push handle 8 is rotatably connected to the base 1, and a fixed knob 9 is installed on the base 1 to fix the push handle 8 in an outwardly opened state, so as to facilitate the stable pushing of the tractor and facilitate the folding and storage of the push handle 8 when idle. Figure 4 As shown, to reduce the footprint.

[0036] In order to better fix the tractor, a fixing rod 11 is penetrated through the vertical thread on the base 1. When in use, the fixing rod 11 can be inserted into the ground to fix the tractor to prevent the tractor from being displaced during traction.

[0037] The working principle of the utility model is as follows: when in use, the first electromagnet 14 and the second electromagnet 15 can be energized, and the two attract each other at this time. When the driving mechanism drives the transmission disk 12 to rotate, the transmission disk 12 rotates synchronously with the take-up drum 3 through the action of the first electromagnet 14 and the second electromagnet 15, and the traction rope is wound up, so that the cable is pulled by the traction rope; when the cable is subjected to a large external resistance, the winding resistance of the take-up drum 3 becomes larger accordingly. When the resistance is greater than the suction force between the first electromagnet 14 and the second electromagnet 15, the first electromagnet 14 and the second electromagnet 15 are separated, and the transmission disk 12 still rotates under the action of the driving mechanism, while the take-up drum 3 does not rotate, thereby effectively preventing the cable from being damaged by excessive force, and when the lever 17 rotates with the transmission disk 12, the lever 17 contacts with the elastic paddle 16, and a clicking sound is emitted, so as to remind the staff to clear the obstacle in time.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
