[0027] In order for those skilled in the art to better understand the technical scheme of the utility model, the following will be combined with the accompanying drawings to further describe the utility model in detail. Figures 1-6 The utility model will be further described in detail.

[0028] The utility model discloses a kind of guiding conveying devices for mica tape insulation corrugated copper sheath cable production, including guiding component of guiding cable and winding component of winding cable, guiding component includes multiple guide parts 1, guide part 1 includes guide frame 31, two guide wheels 32 being arranged in upper and lower interval are provided on guide frame 31, flexible part 33 is provided on guide wheel 32, when guide wheel 32 guides cable, flexible part 33 wraps cable surface, and the hard friction that cable moves and receives is changed into soft friction.

[0029] Specifically, guiding component and winding component are fixedly installed on ground, winding component is used to guide cable to the position of winding component and wind, wherein, in the embodiment, winding component includes winding frame, winding column and drive motor, winding column is rotatably installed on winding frame, drive motor is used to drive winding column to rotate on winding frame, to wind cable, existing cable is guided when producing, multiple guide parts 1 are arranged in production workshop, multiple guide parts 1 are arranged between each work station, guide part 1 is used to guide cable to pass through different work stations, until cable is wound on winding component, existing cable is guided, and staff uses mechanical equipment to pass through two guide wheels 32 being arranged in upper and lower interval and pass through each work station, until the end of cable is connected with winding component, when winding cable, winding component works, and cable is wound, under the traction of winding component, cable passes through each work station along guide wheel 32 on guide part 1, until cable is wound on winding component, and the winding treatment after the conduction of cable is completed.

[0030] However, existing guide wheel 32 is usually made of hard metal or plastic material, however, the surface of existing mica tape mineral insulation corrugated copper sheath cable is provided with an outer protective sleeve made of corrugated copper material, so that the protective sleeve on the outer side of cable and guide wheel 32 are usually contacted in hard friction mode when guide wheel 32 guides cable, which can easily cause the protective sleeve on the surface of cable to be worn.

[0031] To solve the above problem, in the embodiment, flexible part 33 is provided on guide wheel 32, when guide wheel 32 guides cable, flexible part 33 wraps cable surface, and the hard friction that cable moves and receives is changed into soft friction.

[0032] Specifically, the flexible part 33 can be made of flexible materials such as silica gel or rubber (in this embodiment, specifically, rubber), that is, a rubber layer is sleeved on the surface of the guide wheel 32, at this time, as the winding assembly pulls the cable, the cable slides on the guide wheel 32, and the cable contacts the rubber layer on the surface of the guide wheel 32, at this time, a soft friction effect is formed between the cable and the guide wheel 32, and the surface protective sleeve of the cable is prevented from being abraded during transportation.

[0033] Preferably, the guide wheel 32 comprises a connecting rod 321 and two side edge baffles 322, the connecting rod 321 and the two side edge baffles 322 are coaxially arranged, and the connecting rod 321 connects the two side edge baffles 322, the flexible part 33 is arranged outside the connecting rod 321, the two ends of the flexible part 33 are sealingly connected with the two side edge baffles 322 respectively, and the flexible part 33 and the connecting rod 321 are spaced to form a water filling space 5, and a water inlet 6 is arranged on the side edge baffle 322 and communicates with the water filling space 5, and water flows into the water filling space 5 through the water inlet 6 to make the flexible part 33 swell.

[0034] Specifically, before the cable is guided and transported, the staff connects the water filling device with the water inlet 6, the water filling device can be a common water pipe and a water storage tank, the water pipe connects the water storage tank with the water inlet 6, and the water pipe transports the water in the water storage tank to the water filling space 5 through the water inlet 6, when the water filling space 5 is filled with water, the water filling space 5 swells to make the flexible part 33 arch, then, when the cable needs to be guided and transported, the staff needs to pass the cable to be transported through the space between the two guide wheels 32, at this time, the cable is pressed on the flexible part 33 of the lower guide wheel 32 under the action of gravity, at this time, the flexible part 33 is extruded by the cable, and the flexible part 33 is concave downward to form a shape wrapping the cable, when the winding assembly pulls the cable to slide on the guide wheel 32, the cable contacts the flexible part 33, a soft friction effect is formed between the flexible part 33 and the cable, and the surface protective sleeve of the cable is prevented from being abraded during transportation.

[0035] It also needs to be explained that, because water has incompressibility, when the flexible part 33 is concave downward under the pressure of the cable (the downward concave refers to the concave of the flexible part 33 to the direction of the connecting rod 321), the flexible part 33 also wraps the two sides of the cable, when the cable shakes to the two sides (that is, to the direction of the two side edge baffles 322) during movement, the flexible part 33 wrapping the two sides of the cable can reduce the shaking amplitude of the cable, and the cable is prevented from colliding with the two side edge baffles 322 to cause damage to the cable.

[0036] The existing cable will sway on the guide wheel 32 during the guiding transportation process, and the swaying cable is easy to hit the side edge baffle 322 of the guide wheel 32, and the surface of the cable is easy to be damaged.

[0037] Further, the proximal end faces of the two side edge baffles 322 are provided with protection assemblies 7, which are used to protect the cable when the surface of the cable hits the side edge baffles 322; the protection assembly 7 comprises a contact ring 71 coaxial with the side edge baffle 322, the contact ring 71 is sleeved on the outside of the flexible part 33, and the inner circle of the contact ring 71 is spaced apart from the flexible part 33, the contact ring 71 and the side edge baffle 322 are connected through a plurality of buffer springs 72, and the plurality of buffer springs 72 are arranged along the circumference of the side edge baffle 322; the surface of the contact ring 71 is wrapped with a flexible layer 73, which buffers the impact of the cable once; the contact ring 71 and the side edge baffle 322 are further provided with a water storage bag 74, which is connected with the water filling space 5, when the contact ring 71 is extruded, the water in the water storage bag 74 enters the water filling space 5.

[0038] Specifically, when the amplitude of the cable is too large, causing the cable to move towards the two side edge baffles 322, the cable first contacts the surface of the contact ring 71, the flexible layer 73 on the surface of the contact ring 71 is in flexible contact with the cable, avoiding damage to the surface of the cable, and at the same time, the flexible layer 73 buffers the impact of the cable once when the cable contacts the flexible layer 73, if the first buffering of the flexible layer 73 cannot completely eliminate the kinetic energy of the cable, under the impact of the cable, the contact ring 71 moves towards the side edge baffle 322 closest to it, at this time, the buffer spring 72 connected to the contact ring 71 is extruded and deformed, buffering the impact of the cable twice, and because there is a water storage bag 74 between the contact ring 71 and the side edge baffle 322, when the buffer spring 72 connected to the contact ring 71 is contracted, the water storage bag 74 is extruded by the contact ring 71, and the water flow in the water storage bag 74 enters the water filling space 5, the water filling space 5 continues to expand and become larger, increasing the wrapping area between the flexible part 33 and the cable, when the cable moves towards the other side edge baffle 322, the increased flexible part 33 reduces the amplitude of the cable, to reduce the impact force when the cable hits the contact ring 71, protecting the cable.

[0039] In order to transport cables of different sizes, preferably, the connecting rod 321 is a telescopic structure, when the water filling space 5 is filled with water, as the water flow continues to enter the water filling space 5, the connecting rod 321 is elongated; the connecting rod 321 comprises a fixed sleeve 323 and a sliding column 324, one end of the fixed sleeve 323 is connected with one of the side edge baffles 322, one end of the sliding column 324 is connected with the other side edge baffle 322, the other end of the sliding column 324 is inserted into the fixed sleeve 323, and the sliding column 324 and the fixed sleeve 323 are slidingly connected, and the fixed sleeve 323 and the sliding column 324 are connected through a traction spring 325.

[0040] Specifically, when the size of the cable to be transported is too large, causing the guide wheels 32 to be unable to guide the transportation of the cable, the water filling device continues to fill water into the water filling space 5, and as the pressure in the water filling space 5 increases, the sliding column 324 slides along the fixed sleeve 323 under the action of the water flow, at this time, the two side edge baffles 322 are separated from each other, causing the distance between the guide wheels 32 to increase, at this time, the traction spring 325 is stretched, accumulating elastic potential energy; when subsequent transportation of large-size cables is not required, the water in the water filling space 5 is sucked out by the water filling device, at this time, the traction spring 325 releases the accumulated elastic potential energy, the sliding column 324 moves within the fixed sleeve 323, and the two side edge baffles 322 move close to each other, so that the guide wheels 32 return to the initial state.

[0041] At the same time, in order to ensure that the distance between the two guide wheels 32 arranged in an up-down manner can meet the transportation of cables of different sizes, preferably, the guide frame 31 is further provided with an adjusting mechanism 4, the adjusting mechanism 4 is connected with one of the guide wheels 32, and the adjusting mechanism 4 drives the guide wheel 32 connected therewith to move along the vertical direction towards the other guide wheel 32.

[0042] Specifically, the adjusting mechanism 4 comprises a guide sliding groove opened in the guide frame 31 and an electric control telescopic rod, the guide sliding groove is vertically arranged, one of the guide wheels 32 is slidingly installed in the guide sliding groove, and the electric control telescopic rod is fixedly installed on the guide frame 31; a telescopic section of the electric control telescopic rod is connected with the guide wheel 32 slidingly installed in the guide sliding groove, and through the elongation of the electric control telescopic rod, the guide wheel 32 connected with the electric control telescopic rod moves along the vertical direction away from or close to the other guide wheel 32, so as to adjust the distance between the two guide wheels 32, thereby meeting the transportation of cables of different sizes.

[0043] The above only describes certain exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
