Description

Technical Field

[0001] The invention relates to the technical field of equipment related to conveying, winding and connecting electric wires, and in particular to a ground wire storage mechanism with an auxiliary pulling function. Background Art

[0002] The grounding wire of the high-voltage transformer is the most important and direct safety technical measure to ensure the safety of personnel and equipment. Generally, the ground wire will be buried underground for a long time. If a landslide occurs in the mountains or the local personnel are involved in infrastructure expansion, the buried ground wire may be exposed. At this time, the ground wire needs to be re-laid. After the new ground wire is laid, the old ground wire needs to be stored. Generally, it is directly placed in a long strip around or stored with the help of a cable rack.

[0003] However, since the grounding wire is relatively heavy and less prone to deformation than the cable grounding wire, directly winding it with a cable rack will cause uneven winding of the grounding wire, and simply turning the winding shaft to drag the dense, long and non-deformable grounding wire requires a large force, and this will cause uneven force on the winding shaft, which can easily cause the winding shaft to deform. After searching, the Chinese patent with application number: 202010736050.1 and name "A winding rack for grounding wire" discloses a method of winding the grounding wire layer by layer on a winding shaft by driving the threading block to move back and forth by a driving member, but the shortcomings of this patent are that: during the entire process, the grounding wire in the trench is wound around the winding shaft by rotating the winding shaft, and the winding shaft is unevenly stressed during the winding process, which requires a high strength of the winding shaft and is prone to deformation of the winding shaft after long-term use. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a ground wire storage mechanism with an auxiliary pulling function.

[0005] The present invention provides a ground wire storage mechanism with auxiliary pulling function, comprising a frame and a winding shaft installed on the frame, the winding shaft is used to wind the ground wire, the length of the winding shaft is greater than the width of the ground wire, and also comprises a sliding member, the sliding member is horizontally slidably installed on the frame, the sliding member is provided with a ground wire fixing mechanism, the ground wire fixing mechanism is used to clamp and fix the ground wire, the ground wire fixing mechanism divides the ground wire into a winding part and a dragging part, one end of the winding part is connected to the winding shaft;

[0006] The frame is also provided with an auxiliary wire pulling mechanism, which is connected to the sliding member. The auxiliary wire pulling mechanism makes the pulling force of the dragging part greater than the pulling force of the winding part in the initial stage of winding, that is, when the length of the dragging part is greater than the length of the winding part, the pulling force of the dragging part is greater than the pulling force of the winding part.

[0007] When the winding shaft rotates to wind the ground wire around it, the auxiliary wire pulling mechanism assists in pulling the ground wire so that the pulling force of the initial dragging part of the winding is greater than the pulling force of the winding part, thereby reducing the force difference between a certain position and other positions of the winding shaft, thereby increasing the service life of the winding shaft.

[0008] In order to reduce the footprint of the device, preferably, the sliding member has a first station and a second station, the sliding member reciprocates between the first station and the second station, the first station is farther away from the winding shaft relative to the second station, when the sliding member is in the first station, the ground wire fixing mechanism fixes the ground wire, and when the sliding member is in the second station, the ground wire fixing mechanism releases the clamped ground wire.

[0009] Preferably, in some embodiments, the auxiliary pulling mechanism includes a traction rope installed on the sliding member, and the other end of the traction rope is detachably installed on the winding shaft. When the winding shaft rotates, the traction rope is in a stretched state. When the winding shaft rotates, the traction rope is wound around the winding rope, and then the traction rope drives the sliding member to move horizontally, thereby pulling the ground wire away from the winding shaft.

[0010] As a further optimized solution of the present invention, the traction rope is provided with at least two groups, the winding shaft includes a winding part and a traction part, and the traction rope is wound around the traction part when the winding part rotates to wind the ground wire. The traction part is provided with at least two groups, and one group of the traction parts corresponds to one group of the traction ropes.

[0011] As a further optimized solution of the present invention, a sleeve is provided on the outside of the winding shaft, and a fixing part is provided between the sleeve and the winding shaft along the radial direction of the winding shaft so that the winding shaft and the sleeve can rotate simultaneously, the part provided with the sleeve is the traction part, and the outer diameter of the sleeve can be adjusted.

[0012] In some embodiments, preferably, the auxiliary wire pulling mechanism includes a moving mechanism, which drives the sliding member to move on the frame. The moving mechanism can be a screw slider mechanism or a cylinder or electric cylinder in the prior art that can drive the component to move horizontally.

[0013] As a further optimized solution of the present invention, the speed at which the moving machine drives the sliding member to move horizontally is greater than the linear speed of the ground wire on the winding shaft.

[0014] As a further optimized solution of the present invention, the ground wire fixing mechanism includes a bottom support installed on the sliding member, and a clamping block installed above the bottom support through a clamping mechanism. The clamping mechanism drives the clamping block to move in the vertical direction to tighten or loosen the ground wire between the bottom support and the clamping block. The clamping mechanism can be an electric cylinder or a pneumatic cylinder in the prior art or other mechanisms that can drive the plate-like component to move back and forth in the vertical direction.

[0015] As a further optimized solution of the present invention, the bottom support has a lower groove, and the clamping block has a raised portion opposite to the lower groove. The raised portion and the lower groove cause the ground wire between the bottom support and the clamping block to bend and deform. It should be noted that the partial protrusion or bending of the ground wire has little effect on the effect of the ground wire during actual use.

[0016] As a further optimized solution of the present invention, the lower grooves and the protrusions are provided with at least two groups, one group of the lower grooves is opposite to one group of the protrusions, a pre-stretching groove is provided between any two adjacent lower grooves, a deformation interval is formed between the pre-stretching groove and the lower groove, and the top of the clamping block is provided with an elastic extrusion protrusion opposite to the pre-stretching groove, when the clamping block moves downward, the elastic extrusion protrusion contacts the ground wire and squeezes part of the ground wire into the pre-stretching groove, and then the protrusion contacts the ground wire and bends and squeezes the ground wire into the lower groove, and in this process the elastic extrusion protrusion moves upward. This ensures the clamping effect of the ground wire fixing mechanism on the ground wire.

[0017] In the present invention, the proposed ground wire storage mechanism with auxiliary pulling function has a simple structure. The ground wire fixing mechanism separates the ground wire into a winding part and a dragging part, which is connected to the sliding member through the auxiliary pulling mechanism. The auxiliary pulling mechanism makes the pulling force of the dragging part in the initial winding stage greater than the pulling force of the winding part, thereby reducing the technical problem of uneven force on the winding shaft, reducing the force difference of the winding shaft to a certain extent, and thereby increasing its service life.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-Figure 6 The illustrated ground wire storage mechanism with auxiliary pulling function comprises a frame 1 and a winding shaft 2 mounted on the frame 1. As in the prior art, a driving mechanism is also provided for driving the winding shaft 2 to rotate. The winding shaft 2 is used to wind the ground wire. The length of the winding shaft 2 is greater than the width of the ground wire. The sliding member 3 is horizontally slidably mounted on the frame 1. A sliding groove is provided on the frame 1. The sliding member 3 is horizontally slidably mounted in the sliding groove. The sliding displacement of the sliding member 3 relative to the frame 1 is perpendicular to the axis of the winding shaft 2. A ground wire fixing mechanism 4 is provided on the sliding member 3. The ground wire fixing mechanism 4 is used to clamp and fix the ground wire. The ground wire fixing mechanism 4 separates the ground wire into a winding part and a dragging part. One end of the winding part is connected to the winding shaft 2.

[0029] The frame 1 is also provided with an auxiliary wire pulling mechanism 5, which is connected to the sliding member 3. The auxiliary wire pulling mechanism 5 makes the pulling force of the initial dragging part of the winding greater than the pulling force of the winding part.

[0030] It should be noted that in order to achieve uniform winding of the ground wire on the winding shaft 2, the frame 1 is also provided with a wire mechanism (not shown in the figure) that reciprocates left and right and is used for uniform ground wire winding, as in the prior art.

[0031] When the winding shaft 2 rotates, the auxiliary wire pulling mechanism 5 assists in pulling the sliding member 3 to move horizontally and then assists in pulling the dragging part to move closer to the winding shaft 2, reducing the force of the ground wire winding part 20 on the winding shaft 2, thereby reducing the deformation of the winding shaft 2 and increasing its overall service life to a certain extent.

[0032] In order to reduce the footprint of the device, in some embodiments, preferably, the sliding member 3 has a first station and a second station, the sliding member 3 reciprocates between the first station and the second station, the first station is farther away from the winding shaft 2 relative to the second station, when the sliding member 3 slides to the first station, the ground wire fixing mechanism 4 fixes the ground wire, and when the sliding member is in the second station, the ground wire fixing mechanism 4 releases the clamped ground wire.

[0033] like Figure 1-5 In some embodiments shown in the figure, the ground wire fixing mechanism 4 includes a bottom support 40 installed on the sliding member 3, and a clamping block 42 installed above the bottom support 40 through a clamping mechanism 41. The clamping mechanism 41 drives the clamping block 42 to move in the vertical direction to tighten or loosen the ground wire between the bottom support 40 and the clamping block 42. The clamping mechanism 41 can be an electric cylinder or a pneumatic cylinder in the prior art or other mechanism that can drive the plate-like component to move back and forth in the vertical direction. Specifically, the clamping mechanism 41 is an electric cylinder installed on the bottom support 40. When the ground wire is initially wound, the clamping mechanism 41 drives the clamping block 42 to move in the vertical direction. The clamping block 42 moves upward to make the distance between the clamping block 42 and the bottom support 40 relatively large, and then the ground wire passes through the bottom support 40 and the clamping block 42, and then the clamping block 42 moves downward through the clamping mechanism 41 to achieve the clamping of the ground wire; when the winding wheel rotates to wind the ground wire, the auxiliary wire pulling mechanism 5 drives the sliding member 3 to move horizontally to reduce the large force on a certain position of the winding shaft 2. When the sliding member 3 slides to the second station, the winding shaft 2 stops rotating and the clamping mechanism 41 moves upward and moves to the first station, and the above movement is repeated to achieve the winding of the ground wire with auxiliary pulling.

[0034] In order to increase the clamping effect on the ground wire and prevent the ground wire from moving relative to the ground wire clamping mechanism, in some embodiments, preferably, the bottom support 40 has a lower groove 400, and the pressing block 42 has a protrusion 420 opposite to the lower groove 400. The protrusion 420 and the lower groove 400 cause the ground wire between the bottom support 40 and the pressing block 42 to bend and deform. When the ground wire is placed on the bottom support 40, the pressing mechanism 41 drives the pressing block 42 to move downward and causes the upper surface of the bottom support 40 to contact the pressing block 42. 2, and the protrusion 420 moves into the lower groove 400 to bend the ground wire, and the protrusion 420 fixes the ground wire in the lower groove 400. It should be noted that the bending angle of the ground wire is not large, and the depth of the lower groove 400 is less than 20 mm. In this embodiment, the depth of the lower groove 400 is 10 mm, and when the bent ground wire becomes the winding part, the ground wire is wound on the winding shaft 2 due to the rotation of the winding shaft 2. At this time, the bent part will be deformed to a certain extent to make it straight.

[0035] Preferably, if Figure 5 As shown, a through groove 401 is provided on the bottom support 40, and the lower half of the clamping block 42 matches the through groove 401. The setting of the through groove 401 realizes the positioning of the clamping block 42 on the one hand, and prevents the ground wire from deviating from the bottom support 40 when the ground wire is placed on the bottom support 40 on the other hand. The lower groove 400 is provided in the through groove 401.

[0036] In some embodiments, preferably, at least two groups of lower grooves 400 and protrusions 420 are provided, one group of lower grooves 400 is opposite to one group of protrusions 420, and a pre-stretching groove 402 is provided between any two adjacent lower grooves 400, and a deformation interval is formed between the pre-stretching groove 402 and the groove, and the ground wire located between the deformation interval is clamped by the upper surface of the bottom support 40 and the lower surface of the pressing block 42, and the lower surface of the pressing block 42 is provided with an elastic extrusion protrusion 421 opposite to the pre-stretching groove 402, and the elastic extrusion protrusion 421 can be elastically deformed in the vertical direction, and when no force is applied, the elastic extrusion protrusion 421 is elastically extruded. The lower surface of the pressing protrusion 421 is below the protruding portion 420, and the depth of the pre-stretching groove 402 is greater than the depth of the lower groove 400. When the clamping block 42 moves downward, the elastic extrusion protrusion 421 first contacts the ground wire and squeezes the ground wire into the pre-stretching groove 402, and then the protruding portion 420 contacts the ground wire and moves downward. When the protruding portion 420 drives the ground wire to move in the groove, the protruding portion 420 squeezes the ground wire and the elastic extrusion protrusion 421 deforms, causing the ground wire in the pre-stretching groove 402 to move to both sides, thereby preventing the ground wire between the two lower grooves 400 from being pulled and deformed.

[0037] Specifically, the elastic extrusion protrusion 421 includes a strip-shaped protrusion and an elastic member installed between the strip-shaped protrusion and the pressing block 42. The elastic member is a spring. Of course, those skilled in the art can adopt other elastic structures that can be elastically deformed in the vertical direction.

[0038] The lower groove 400 is an arc-shaped groove, and the lower surface of the protrusion 420 is an arc-shaped surface, which is convenient for clamping the ground wire.

[0039] In some embodiments, preferably, the auxiliary wire pulling mechanism 5 includes a traction rope 50 installed on the sliding member 3, and the other end of the traction rope 50 is detachably installed on the winding shaft 2. Specifically, the traction rope 50 can be installed on the outside of the winding shaft 2 by means of a hook. When the winding shaft 2 rotates, the traction rope 50 is in a stretched state, and the traction rope 50 drives the sliding member 3 to move closer to the winding shaft 2. When the winding shaft 2 rotates, the traction rope 50 is wound around the winding rope, and then the traction rope 50 drives the sliding member 3 to move horizontally, thereby pulling the ground wire away from the winding shaft 2.

[0040] As a further optimized solution of the present invention, at least two groups of traction ropes 50 are provided, and the winding shaft 2 includes a winding part 20 and a traction part 21. When the winding part 20 rotates to wind the ground wire, the traction rope 50 is wound on the traction part 21. The traction part 21 is provided with at least two groups, one group of traction parts 21 corresponds to one group of traction ropes 50, and the traction part 21 can rotate relative to the winding part 20, and a detachable clamping piece 7 can be provided between the traction part 21 and the winding part 20 to make the traction part 21 rotate synchronously with the winding part 20. When the sliding part 3 moves from the first station to the second station, the traction part 21 rotates synchronously with the winding part 20. After the sliding part 3 moves to the second station, the clamping piece 7 is removed so that the traction part 21 can rotate relative to the winding part 20, so that the traction rope 50 wound on the traction part 21 can be wound off the traction part 21. It should be noted that a driving mechanism for driving the winding part 20 to rotate is also included. The driving mechanism can be a motor and a gear transmission mechanism in the prior art (not shown in the figure).

[0041] As a further optimized solution of the present invention, a sleeve 6 is sleeved on the outside of the winding shaft 2, and a clamping piece 7 is provided between the sleeve 6 and the winding shaft 2 along the radial direction of the winding shaft 2 so that the winding shaft 2 and the sleeve 6 can rotate simultaneously. The part on which the sleeve 6 is sleeved is the traction part 21, and the outer diameter of the sleeve 6 can be adjusted. Sleeves 6 of different sizes can be replaced, thereby ensuring that the outer diameter of the sleeve 6 is larger than the outer diameter of the winding part 20 after winding the ground wire, thereby avoiding the traction rope 50 from being in a loose state during the winding process.

[0042] In some embodiments, the sleeve 6 includes a middle connection 60 connected to the winding axis, the middle connection 60 is sleeved on the outside of the winding shaft 2 and fixed to the winding shaft 2 by a clamping piece 7, the clamping allows the middle connection 60 to rotate synchronously with the winding shaft 2, and the middle connection 60 can be rotated relative to the winding shaft 2 by removing the clamping piece 7; the clamping piece 7 is coaxial with the axis of the middle connection 60 through the winding shaft 2, and a mounting disk 62 is provided on the outer side of the middle connection 60, and a plurality of support rods 61 that can be adjusted to the distance from the axis of the winding shaft 2 are installed on the mounting disk 62, and the traction rope 50 is wound around the outside of the support rods 61; specifically, a plurality of groups of mounting holes are opened on the mounting disk 62, and the distances between any two adjacent groups of mounting holes and the axis of the winding shaft 2 are not equal. When the support rod 61 is installed in the mounting holes at different positions, the outer diameter of the sleeve 6 wrapped around the traction rope 50 is changed.

[0043] Embodiment 2:

[0044] like Figure 6 The difference between the present embodiment shown and the above-mentioned embodiment is that the auxiliary wire pulling mechanism 5 includes a moving mechanism, which drives the sliding member 3 to move on the frame 1. The moving mechanism can be a screw slider mechanism or a cylinder or electric cylinder in the prior art that can drive the component to move horizontally. The moving mechanism in this embodiment is a screw slider mechanism.

[0045] In this embodiment, preferably, the speed at which the moving machine drives the sliding member 3 to move horizontally is greater than the linear speed of the ground wire on the winding shaft 2, thereby ensuring that the tension of the ground wire in the dragging part is greater than the tension of the winding part 20.
