Description

Technical Field

[0001] The present invention relates to the technical field of electric power wire installation tools, and particularly relates to a strain clamp for electric power engineering. Background Art

[0002] A strain clamp is a key fitting used to fix electric power wires and bear their tension in a transmission line. Its main functions include: anchoring and bearing mechanical loads. On a strain tower, corner tower or terminal tower, the strain clamp anchors the electric power wire and bears the longitudinal tension of the line to prevent the electric power wire from loosening or falling off due to wind vibration, icing or temperature change; dispersing stress, dispersing the stress of the electric power wire through a clamping structure, reducing local stress concentration, and protecting the electric power wire from damage.

[0003] Existing traditional strain clamps mostly adopt the connection method of U-shaped bolts and nuts. During the installation process, it is necessary to frequently turn multiple groups of U-shaped bolts and nuts, making the installation reliability dependent on manual operation. The tightening torque of the bolts needs to be strictly controlled. Insufficient torque will cause slippage, and excessive torque will damage the electric power wire. It is difficult to precisely control during on-site construction; moreover, the U-shaped bolt and the surface of the electric power wire are connected by hard pressing, and excessive local pressure may cause deformation or broken strands of the outer aluminum strands of the electric power wire, especially under long-term vibration or dynamic load, which will accelerate the fatigue damage of the electric power wire and shorten the service life of the electric power wire. Summary of the Invention

[0004] The purpose of the present invention is to provide a strain clamp for electric power engineering, in which the buckle plate component is set to be quickly inserted and connected with the Y-shaped component, and an opening and closing rotating plate formed by a screwing adjustment bolt is arranged at the outer bottom of the Y-shaped component, and elastic rotating plates that elastically rotate inward symmetrically at the bottom end of the buckle plate are provided. Cooperating with the movement of the conical column driven by the adjustment bolt and the spherical column on the side of the passive slider, the pressing action of the buckle plate component and the Y-shaped component on the electric power wire can be quickly and safely formed.

[0005] The purpose of the present invention is achieved through the following technical solution. A strain clamp for electric power engineering includes a Y-shaped component, an adjustable tooth component, a buckle plate component, an elastic tooth component and a combined fastening component. The adjustable tooth component includes a vertical frame body and an adjustment bolt. The buckle plate component includes a buckle plate. The elastic tooth component includes a bottom column. The combined fastening component includes a conical column, a pressing inclined surface and a spherical column; The vertical frame body is fixedly connected to the outer bottom of the main body of the Y-shaped component. The adjustment bolt is threadedly connected to the vertical frame body. The outer bottom of the Y-shaped component is rotatably connected with an opening and closing rotating plate symmetrically centered on the adjustment bolt. The top of the adjustment bolt is rotatably connected with a synchronous rotating seat. Both ends of the synchronous rotating seat are rotatably connected with a pushing connecting rod. One end of the pushing connecting rod on the same side is rotatably connected to the middle of the opening and closing rotating plate; The buckle plate can be slidably inserted into the main body of the Y-shaped component. The bottom columns are symmetrically fixedly connected to the bottom end of the buckle plate. Each group of bottom columns is elastically and rotatably connected with an elastic rotating plate inward; The conical column is fixed to the top of the adjusting bolt, the outer bottom of the Y-shaped component body is elastically slid inwardly with passive sliders on both sides, the pressing inclined surface is set at the bottom of the passive slider, and the spherical column is fixed to the inner middle of the passive slider.

[0006] The use process of the technical solution of the present invention is as follows: The Y-shaped component is connected as a whole to the pole tower hanging point through a hanger; Before the power conductor is installed, the gusset plate component and the Y-shaped component are in a separated state, and the opening and closing rotary plate is in the retracted limit position; When the adjusting bolt is turned to control the opening and closing rotary plate to be in the retracted limit position, the conical column is in the downward limit position, at which time the inner end of the spherical column and the small conical end of the outer conical surface of the conical column slide tangentially, and the passive slider is in the inward retracted limit position; After the power conductor is inserted into the groove in the main body of the Y-shaped component, the gusset plate component can be positioned and slidably inserted with the Y-shaped component through the gusset plate, so that the bottom end of the gusset plate and the groove in the main body of the Y-shaped component together form a wrapping for the power conductor; By screwing the adjusting bolt, the adjusting bolt and the frame body form a threaded connection, which drives the movement of the synchronous rotary seat. The synchronous rotary seat forms a screw connection with the opening and closing rotary plates at different positions through the push connecting rods at both ends, which can drive the symmetrically distributed opening and closing rotary plates to form an opening and closing action. When the two groups of opening and closing rotary plates are opened outward synchronously, the teeth on the outer side of the opening and closing rotary plates can contact the teeth on the inner side of the elastic rotary plates to form a mutual clamping connection, so that the buckle plate component and the Y-shaped component form a locking connection; And synchronously, the adjustment bolt drives the movement of the conical column. When the conical column moves upward, the outer conical surface of the conical column from the small conical end to the large conical end forms a sliding tangential fit with the inner end of the spherical column, thereby pushing the passive slider outward, so that the pressing inclined surface forms a sliding tangential fit with the outer cylindrical surface of the bottom column. When the pressing inclined surface moves outward, it can push the bottom column downward, thereby driving the buckle plate to move downward; Since the teeth on the outer side of the opening and closing rotary plate and the teeth on the inner side of the elastic rotary plate only allow the elastic rotary plate to move downward after contact, with the cooperation of the elastic rotary plate's own inward elastic rotation, as the passive slider is twisted, on the one hand, it can drive the opening and closing rotary plate to open outward, and lock the teeth on the outer side of the opening and closing rotary plate and the teeth on the inner side of the elastic rotary plate more safely and firmly, and on the other hand, drive the buckle plate to press the power conductor through the bottom column.

[0007] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) Compared with the conventional method of fixing and compressing the power conductor in the Y-shaped member by connecting the U-shaped bolts and nuts, the present invention adopts a quick-insert connection method, which does not require repeated screwing of nuts connected to different U-shaped bolts, thereby improving work efficiency to a certain extent; (2) After the power conductor is inserted into the groove of the Y-shaped component body, in order to enable the buckle component to securely, reliably and quickly clamp the power conductor, the present invention not only sets a one-way mutual locking method between the outer teeth of the opening and closing rotating plate and the inner teeth of the elastic rotating plate, but also arranges the symmetrically distributed opening and closing rotating plates to form a synchronous opening and closing action by screwing the adjusting bolt, and arranges the elastic rotating plate to be elastically rotated inward. As a result, after the buckle component and the Y-shaped component wrap the power conductor, the greater the outward expansion action of the opening and closing rotating plate driven by screwing the adjusting bolt, the greater the locking degree between the opening and closing rotating plate and the elastic rotating plate, and the safer the connection between the opening and closing rotating plate and the elastic rotating plate becomes; (3) Further, with the screwing action of the adjusting bolt, the inner ends of the conical column and the spherical column can also form a sliding tangential fit, pushing the passive slider to move outward, and using the sliding tangential fit formed by the pressing inclined surface and the outer cylindrical surface of the bottom column. Thus, by screwing the adjusting bolt, both the downward pressing action of the buckle on the power conductor can be completed, and the greater the distance the buckle moves downward, the greater the locking force between the opening and closing rotating plate and the elastic rotating plate, so that the pressing work on the power conductor can be safely and quickly achieved.

[0013] As Figures 1 - 16 shown, a strain clamp for a power project, the groove in the main body of the Y-shaped member 1 is used to place a power conductor. The vertical frame body 202 is fixedly connected to the outer bottom of the main body of the Y-shaped member 1. The adjusting bolt 204 is threadedly connected to the vertical frame body 202. The opening and closing rotary plates 206 are rotatably connected to the outer bottom of the Y-shaped member 1 symmetrically with the adjusting bolt 204 as the center. The top of the adjusting bolt 204 is rotatably connected to the synchronous rotary seat 211. Both ends of the synchronous rotary seat 211 are rotatably connected to the pushing connecting rods 213. One end of the pushing connecting rods 213 on the same side is rotatably connected to the middle of the opening and closing rotary plate 206. Rotating the adjusting bolt 204 can drive the symmetrically distributed opening and closing rotary plates 206 to form a synchronous opening and closing action; The buckling plate 301 can be slidably inserted into the main body of the Y-shaped member 1 to form a crimping of the power conductor placed in the groove in the main body of the Y-shaped member 1. The bottom columns 402 are symmetrically fixedly connected to the bottom end of the buckling plate 301. Each group of bottom columns 402 has an elastic rotary plate 403 rotatably connected inwardly. And when the opening and closing rotary plate 206 is in the retracted position, the inward extreme elastic rotary connection position of the elastic rotary plate 403 will not interfere with the sliding insertion action of the buckling plate 301 and the main body of the Y-shaped member 1; The conical column 501 is fixedly connected to the top of the adjusting bolt 204. Passive sliders 504 are elastically slidably connected inwardly on both sides of the outer bottom of the main body of the Y-shaped component 1. The pressing inclined surface 505 is arranged at the bottom end of the passive slider 504. The spherical column 508 is fixed to the inner middle part of the passive slider 504, and both can form a sliding tangent fit with the outer conical surface of the conical column 501. When the adjusting bolt 204 is screwed to drive the conical column 501 to move upward, the sliding tangent fit formed between the conical column 501 and the inner end of the spherical column 508 can push the pressing inclined surface 505 to form a sliding tangent fit with the outer cylindrical surface of the bottom column 402. Here’s how it works: The Y-shaped member 1 is connected as a whole to the pole tower hanging point through a hanging piece; Before the power conductor is installed, the gusset member 3 and the Y-shaped member 1 are in a separated state, and the opening and closing rotary plate 206 is in a retracted limit position; When the adjusting bolt 204 is screwed to control the opening and closing rotary plate 206 to be in the retracted limit position, the conical column 501 is in the downward limit position, at which time the inner end of the spherical column 508 and the small conical end of the outer conical surface of the conical column 501 are tangentially matched in sliding, and the passive slider 504 is in the inward retracted limit position under the condition that the passive slider 504 itself moves inwardly with the elastic force support. At this time, the passive slider 504 will not interfere with the sliding and inserting cooperation between the gusset member 3 and the Y-shaped member 1; After the power conductor is inserted into the groove in the main body of the Y-shaped component 1, the pinch plate component 3 can form a positioning slide insertion with the Y-shaped component 1 through the pinch plate 301, so that the bottom end of the pinch plate 301 and the groove in the main body of the Y-shaped component 1 together form a wrapping for the power conductor, and the power conductor is in an uncompressed state at this time; By screwing the adjusting bolt 204, the adjusting bolt 204 and the stand body 202 form a threaded connection, driving the movement of the synchronous rotary seat 211. The synchronous rotary seat 211 forms a screw connection with the opening and closing rotary plates 206 at different positions through the push connecting rods 213 at both ends, which can drive the symmetrically distributed opening and closing rotary plates 206 to form an opening and closing action. When the two groups of opening and closing rotary plates 206 are synchronously opened outward, the teeth on the outer side of the opening and closing rotary plates 206 can contact the teeth on the inner side of the elastic rotary plate 403 to form a mutual clamping connection, so that the buckle plate component 3 and the Y-shaped component 1 form a locking connection; And synchronously, the adjusting bolt 204 drives the movement of the conical column 501. When the conical column 501 moves upward, the outer conical surface of the conical column 501 from the small conical end to the large conical end forms a sliding tangential fit with the inner end of the spherical column 508, thereby pushing the passive slider 504 outward, so that the pressing inclined surface 505 forms a sliding tangential fit with the outer cylindrical surface of the bottom column 402. Since the pressing inclined surface 505 itself is opened in the outward and upward direction, when the pressing inclined surface 505 moves outward, it can push the bottom column 402 to move downward, thereby driving the buckle plate 301 to move downward; Since the teeth on the outer side of the opening and closing rotating plate 206 only allow the elastic rotating plate 403 to move downward after contacting the teeth on the inner side of the elastic rotating plate 403, with the cooperation of the inward elastic rotation of the elastic rotating plate 403 itself, as the passive slider 504 is screwed, on the one hand, it can drive the opening and closing rotating plate 206 to open outward, locking the teeth on the outer side of the opening and closing rotating plate 206 and the teeth on the inner side of the elastic rotating plate 403 more securely. On the other hand, it drives the buckle plate 301 to press the power conductor through the bottom post 402; That is to say, as the passive slider 504 is screwed, a pressing action of the power conductor between the buckle plate 301 and the groove body of the Y-shaped member 1 can be formed. And the tighter the power conductor is pressed by the buckle plate 301 and the Y-shaped member 1, the larger the opening angle of the opening and closing rotating plate 206 outward, and the more secure the locking between the elastic rotating plate 403 and the opening and closing rotating plate 206.

[0014] The specific structure of the Y-shaped member 1 is as Figure 3 shown. The Y-shaped member 1 is integrally cast. The Y-shaped wire clamp 101 is the main structure of the Y-shaped member 1. Reinforcing rib plates 102 are fixedly connected in a distributed manner at the outer bottom of the Y-shaped wire clamp 101, aiming to improve the support and tensile strength of the Y-shaped wire clamp 101; The fastening connection column 103 is horizontally fixedly connected at the corner of the Y-shaped wire clamp 101. A U-shaped connection ring, an extension rod, and a pole fastening clamp are connected between the fastening connection column 103 and the pole tower, for realizing the connection and fixation of the whole Y-shaped member 1 with the pole tower; Opening and closing rotating seats 104 are fixedly connected in pairs on both sides of the outer bottom of the Y-shaped wire clamp 101. The paired opening and closing rotating seats 104 are respectively fixedly connected with different reinforcing rib plates 102; Clamping sliding seats 105 are symmetrically fixedly connected on both sides of the Y-shaped wire clamp 101; Pressing grooves 106 are symmetrically opened at the top of the Y-shaped wire clamp 101, for providing space for the downward movement and pressing action of the buckle plate 301.

The adjusting bolt 204 is threadedly connected with the fixing nut 203; The bottom end of the moving column 205 is fixedly connected coaxially with the top end of the adjusting bolt 204; The outer side of the opening and closing rotating plate 206 is provided with buckle teeth 207. At both sides of the top end of each group of opening and closing rotating plates 206, there are fixedly connected opening and closing rotating shafts 208. The opening and closing rotating shafts 208 on the same side are rotatably connected to the opening and closing rotating seats 104. When the adjusting bolt 204 is screwed, the opening and closing rotating plate 206 can rotate with the opening and closing rotating shaft 208 as the reference to form an opening and closing action; A middle position groove 209 is opened at the bottom end of the main body of the opening and closing rotating plate 206.

[0016] The specific structures of the buckle plate member 3 and the elastic tooth component 4 are as Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown. Positioning columns 302 are fixedly connected to the bottom corners of the buckle plate 301, and each group of positioning columns 302 can be inserted into the buckle sliding seat 105 in a facing manner. The buckle pressing blocks 303 are fixedly connected to the bottom end of the buckle plate 301 in an arranged manner, which is used to form the crimping work on the power conductor penetrating into the Y-shaped wire clamp 101; And the buckle pressing block 303 is made of engineering plastic material, and its inner surface is provided with knurling, which can improve the friction force in contact with the power conductor and improve the safety of the buckle pressing block 303 for crimping the power conductor; The side standing plates 401 are symmetrically fixedly connected to the bottom end of the buckle plate 301. The bottom column 402 is fixedly connected to the bottom end of the side standing plate 401. The side hole 407 is opened in the middle of the position where the side standing plate 401 is connected to the bottom column 402, which is used to provide a space for the sliding tangential fit between the pressing inclined surface 505 and the outer circular surface of the bottom column 402; The top end of the elastic rotating plate 403 is fixedly connected with an elastic rotating shaft 404 horizontally. The elastic rotating plate 403 is rotatably connected to the bottom column 402 through the elastic rotating shaft 404; Elastic teeth 405 are opened on the inner side of the elastic rotating plate 403, and the tooth shape of the elastic teeth 405 matches the tooth shape of the buckle teeth 207, and only allows the elastic rotating plate 403 to move downward along the fit with the opening and closing rotating plate 206 alone; An elastic connecting plate 406 is symmetrically and fixedly connected between the outer side of the elastic rotating plate 403 and the outer side of the side standing plate 401. The elastic connecting plate 406 can provide an elastic thrust for the elastic rotating plate 403 to rotate inward relative to the elastic rotating shaft 404, so as to form a clamping and locking fit between the clamping teeth 207 and the elastic clamping teeth 405; And because the elastic rotating plate 403 itself is formed with an elastic thrust to rotate inward by the elastic connecting plate 406, that is to say, an elastic locking will be formed between the clamping teeth 207 and the elastic clamping teeth 405, which can, to a certain extent, eliminate the adverse influence of the vibration of the power conductor on the connection of this device; A positioning groove 408 is also opened in the middle of the inner side of the elastic rotating plate 403 to eliminate the interference in the cooperation with the pushing connecting rod 213.

[0017] The specific structure of the combined fastening assembly 5 is as shown in Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 shown. The conical column 501 is fixedly connected to the top end of the moving column 205. The rubber extrusion column 502 is fixedly connected to the top end of the conical column 501 and will not interfere with the sliding tangential fit between the outer conical surface of the conical column 501 and the inner end of the spherical column 508; And when the adjusting bolt 204 is screwed to drive the conical column 501 to move upward to form a sliding tangential fit with the spherical column 508, so that the passive slider 504 moves outward and presses the buckle plate 301 downward, as the rubber extrusion column 502 moves upward, after the rubber extrusion column 502 passes through the bottom hole 201, it can form contact extrusion on the bottom surface of the power conductor. Cooperating with the pressing action of the pressing block 303 on the top surface of the power conductor, it can, to a certain extent, improve the safety and reliability of locking the power conductor; The bottom standing seats 503 are symmetrically arranged on both sides of the bottom hole 201 and are both fixedly connected to the outer bottom of the Y-shaped wire clamp 101.

The two ends of the compression spring 507 are respectively clamped in different inner fixing holes 509. The purpose of opening the inner fixing holes 509 is to facilitate the clamping connection of the compression spring 507 and improve the elastic stroke of the compression spring 507 within a limited space range; A pair of sliding seats 510 are fixedly connected to the bottom end of each group of bottom standing seats 503.
