Description

Technical Field

[0001] The invention relates to a wire drawing electric device and a use method thereof, belonging to the technical field of electric power. Background Art

[0002] State Grid Corporation of China has established the strategic goal of "three types, two networks, and world-class" in the new era. Provincial and municipal companies are also actively exploring and advancing the construction and transformation of power grids at all levels. Among them, the construction of distribution networks cannot be ignored. In the construction of distribution networks, in order to prevent the lines from being damaged by strong wind loads, or to increase the stability of poles in areas with loose soil, guy wires should also be set. The role of guy wires is to withstand poles with relatively significant fixed unbalanced loads, prevent line towers from overturning, and towers from bearing excessive bending moments, so as to increase the stability of towers.

[0003] During the construction of power lines, the method of making the wire terminal is to bend the steel strand into a U-shaped bend and then insert it into the wedge-shaped wire clamp slot for fixing. The traditional method is for on-site workers to do it manually, but this method has the following disadvantages: ① The steel strand is relatively hard, and it is difficult to bend the bend manually, which is laborious; ② The size of the U-shaped bend is not easy to fit tightly with the tongue of the wedge-shaped wire clamp; ③ It needs to be hit with a hammer, and the anti-corrosion layer on the wire clamp is easily damaged during the hammering, affecting the installation quality of the wire clamp. Summary of the invention

[0004] The object of the present invention is to provide a wire drawing electric device and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a wire drawing electric device, comprising a power device (1) that moves up and down, the power device (1) is connected to a support structure (3), and a piston push rod (2) that moves back and forth is arranged in the power device (1), a main shaft (4) is fixed on the piston push rod (2), and the main shaft (4) extends from both the front and back sides of the support structure (3), the main shaft (4) extending from the front side of the support structure (3) is hinged to a left support rod (5.1) and a right support rod (5.2), and the main shaft (4) extending from the back side of the support structure (3) is hinged to a left support rod (5.1) and a right support rod (5.2). The left support rod (5.1) and the right support rod (5.2) are respectively hinged at the middle of the left turning arm (6.1) and the right turning arm (6.2); one end of the left turning arm (6.1) and the right turning arm (6.2) are coaxially hinged to the detachable center wheel (8), and the other ends of the left turning arm (6.1) and the right turning arm (6.2) are respectively hinged to the left extrusion wheel (7.1) and the right extrusion wheel (7.2); the back of the supporting structure (3) is also provided with a wire clamp groove (10) rigidly connected thereto, and the wire clamp groove (10) and the tongue plate groove (9) are in a vertical corresponding relationship.

[0006] As a further solution of the present invention, the left extrusion wheel (7.1) and the right extrusion wheel (7.2) are pulleys with arc-shaped grooves on the edges, which are used to adapt to steel strands of different specifications and models and clamp them in the grooves in the forward direction.

[0007] As a further solution of the present invention, the center wheel (8) is composed of two half-groove pulleys with only half a groove; after the two half-groove pulleys are spliced ​​back to back, they form a complete pulley with an arc-shaped groove on the edge, which can adapt to steel strands of different specifications and models and clamp them in the groove in the forward direction; at the same time, the top half piece is removed from the supporting structure (3) to facilitate the removal of the steel strand that has been bent into a U shape.

[0008] As a further solution of the present invention, the center wheel (8) has different sizes and can be removed and replaced as a whole from the supporting structure (3) so as to correspond to tongue plates of wedge-shaped wire clamps of different specifications and models, so that the steel strands are bent to an arc that matches the wedge-shaped wire clamp.

[0009] As a further solution of the present invention, the power device is an electric hydraulic device or a linear motor. The internal piston push rod is controlled by the staff by wire or remote control to achieve linear reciprocating motion within a certain range, thereby pushing or loosening the left support rod (5.1) and the right support rod (5.2) hinged on the main shaft (4) and the rigidly connected tongue plate groove (9).

[0010] The method of using the pull wire to make an electric device includes the following steps:

[0011] Step 1: Select steel strands and wedge-shaped wire clamps of matching specifications and models, and replace the center wheel (8) with a suitable size; put the outer frame of the wedge-shaped wire clamp on the long end of the steel strand in the correct direction in advance, in preparation for step 3;

[0012] Step 2: The staff moves the piston push rod (2) upwards by wire control or remote control. With the support of the two support rods (5.1 / 5.2), the two crank arms (6.1 / 6.2) are folded upwards, pushing the two extrusion wheels (7.1 / 7.2) to bend the steel strand into a U-shape with the same arc as the groove of the center wheel (8);

[0013] Step 3: Pass the short end of the steel strand through the pre-set wedge-shaped wire clamp, and slide the wedge-shaped wire clamp to the U-shaped bending side of the steel strand by hand; when the wedge-shaped wire clamp is slid to a point where it cannot be pushed, remove the upper half of the center wheel (8), take out the U-shaped steel strand, and put the tongue plate of the wedge-shaped wire clamp into the U-shaped part;

[0014] Step 4: Use the reverse side of the device to place the upper end of the wedge-shaped wire clamp into which the U-shaped steel strand is placed against the wire clamp groove (10). Then, the staff uses wire control or remote control to move the piston push rod (2) upward, and the tongue plate groove (9) squeezes the U-shaped steel strand together with the tongue plate upward, so that the steel strand, the tongue plate, and the outer frame of the wedge-shaped wire clamp fit tightly together, thus completing the entire process of wire pulling.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The U-shaped bend made by pulling the wire is easy to be folded, saving time and effort; 2. U-shaped steel strand clamps with different bending degrees can be made according to different types of wire clamps, even if the U-shaped steel strand fits tightly with the tongue plate of the wedge-shaped wire clamp; 3. The anti-corrosion layer on the wire clamp will not be damaged; 4. The entire production process is standardized, the work steps are optimized, and the production efficiency is improved.

[0028] The left extrusion wheel (7.1) and the right extrusion wheel (7.2) are pulleys with arc grooves on the edges, which are used to adapt to steel strands of different specifications and types, and clamp them in the grooves in the forward direction. The center wheel (8) is composed of two half-groove pulleys with only half grooves; after the two half-groove pulleys are spliced ​​back to back, a complete pulley with arc grooves on the edges is formed, which is used to adapt to steel strands of different specifications and types, and clamp them in the grooves in the forward direction; at the same time, the top half piece is removed from the support structure (3) to facilitate the removal of the steel strand that has been bent into a U shape. The center wheel (8) has different sizes and is removed and replaced as a whole from the support structure (3), so as to correspond to the tongue plates of wedge-shaped wire clamps of different specifications and types, so that the steel strand is bent to an arc that matches the wedge-shaped wire clamp. The electric hydraulic device or the linear motor (1) is a selective relationship, and the internal piston push rod (2) can be controlled by the staff by wire or remote control to achieve linear reciprocating motion within a certain range, thereby pushing (or loosening) the left support rod (5.1) and the right support rod (5.2) hinged on the main shaft (4), as well as the rigidly connected tongue plate groove (9).

[0029] The method of using the pull wire to make an electric device includes the following steps:

[0030] Step 1: According to the requirements of relevant power regulations, select steel strands and wedge-shaped wire clamps of matching specifications and models, and replace the center wheel (8) of appropriate size; put the outer frame of the wedge-shaped wire clamp on the long end of the steel strand in the correct direction in advance, ready for step 3;
