Description

Technical Field

[0001] The present invention relates to the technical field of equipment installation, and particularly relates to a shock-absorbing clamping device for a power equipment wiring terminal and a working method thereof. Background Art

[0002] During the installation process of power equipment, it is often necessary to connect transmission cables. The traditional methods include manual winding for connection, adding U-shaped clamps for connection clamping, or using some wiring clamps to connect and clamp the wire ends by extrusion. However, during use, power equipment often generates vibrations at a certain frequency. Due to the continuous occurrence of the vibration frequency, once the connection position is not firm, loosening will occur, which will affect the stability of power transmission at best and may cause the cable to disconnect and fall onto the equipment, resulting in equipment damage or accidental electric shock and death of personnel at worst.

[0003] Based on the above problems, the present invention proposes a shock-absorbing clamping device for a power equipment wiring terminal. Summary of the Invention

[0004] Aiming at the problems in the above technical background, the purpose of the present invention is to provide a shock-absorbing clamping device for a power equipment wiring terminal, which solves the problems of low wiring strength and poor seismic performance of the existing wiring clamping devices in the background art.

[0005] In order to achieve the above purposes, the technical solution adopted by the present invention is as follows:

[0006] A shock-absorbing clamping device for a power equipment wiring terminal includes two groups of symmetrically installed C-shaped frames. The inner sides of the two ends of the two groups of C-shaped frames are fixedly installed on the front and rear surfaces of two groups of symmetrically installed wire positioning mechanisms for the installation and positioning of two wire ends to be connected by bolting. The wire positioning mechanism includes an upper wire end fixed installation block and a lower wire end fixed installation block that can be slidably installed. At the same time, a rotary wiring mechanism for rotary winding and clamping of the wire is installed between the two groups of wire positioning mechanisms. An anti-rotation limit mechanism for preventing rotation after wiring is installed on the rotary wiring mechanism. The rotary wiring mechanism is composed of an upper rotary wiring clamping block and two groups of symmetrically installed lower rotary wiring clamping blocks.

[0007] Further, a through upper wire end jack is horizontally provided in the upper wire end fixed mounting block. At the same time, a first conical groove for facilitating wire winding is provided at one end of the upper wire end jack close to the patch cord mechanism. One end of the upper wire end fixed mounting block close to the patch cord mechanism is provided with an upper semi-circular rotating guide rail groove. The upper semi-circular rotating guide rail groove is communicated with a concentric upper semi-circular rotating guide rail anti-disengagement groove at the inner bottom of the upper wire end fixed mounting block. Symmetrically arranged side grooves are provided at the bottoms of the front and rear surfaces of the upper wire end fixed mounting block. A sliding guide rail is installed in the side grooves. The upper wire end fixed mounting block is slidably mounted on the top of the lower wire end fixed mounting block through the symmetrically arranged sliding guide rails at the front and rear.

[0008] Furthermore, symmetrically arranged guide rail clamping blocks are provided at the front and rear of the top of the lower wire end fixed mounting block. The sliding guide rails provided at the front and rear of the bottom of the upper wire end fixed mounting block are slidably mounted on the guide rail clamping blocks. And the bottom surface of the upper wire end fixed mounting block is fitted and mounted with the top surface of the lower wire end fixed mounting block. A through lower wire end jack is horizontally provided in the lower wire end fixed mounting block. A second conical groove for facilitating wire winding is provided at one end of the lower wire end jack close to the patch cord mechanism. A lower semi-circular rotating guide rail groove is provided on one side surface of the lower wire end fixed mounting block outside the second conical groove. The lower semi-circular rotating guide rail groove is communicated with a concentric lower semi-circular rotating guide rail anti-disengagement groove at the inner bottom of the lower wire end fixed mounting block. And the upper semi-circular rotating guide rail groove and the lower semi-circular rotating guide rail groove are concentric and have the same horizontal depth.

[0009] Furthermore, upper semi-circular rotating blocks are symmetrically installed at the left and right ends of the upper rotating patch cord clamping block. An upper semi-circular anti-disengagement block is installed inward at the outer end of the upper semi-circular rotating block. The upper semi-circular rotating blocks at both ends are rotatably installed in the upper semi-circular rotating guide rail grooves on the inner sides of the upper wire end fixed mounting blocks installed on both sides of the upper rotating patch cord clamping block. At the same time, the upper semi-circular anti-disengagement blocks are rotatably installed in the upper semi-circular rotating guide rail anti-disengagement grooves. A semi-cylindrical upper rotating patch cord cavity with openings at both ends and the bottom is provided inside the upper rotating patch cord clamping block. A rotating patch cord plate with a flush bottom surface is provided in the middle of the upper rotating patch cord cavity. An upper rotating block through hole that coincides with the horizontal projection of the upper wire end jack is provided on the rotating patch cord plate. Third conical grooves for facilitating wire winding are symmetrically provided at both ends of the upper rotating block through hole. Lower rotating patch cord clamping blocks with a horizontal width half of that of the upper rotating patch cord clamping block and the same longitudinal width are symmetrically installed at the bottom of the upper rotating patch cord clamping block.

[0010] Further, the lower rotary wiring clamping block is provided with a lower rotary wiring cavity with an opening facing upward and laterally outward. At the same time, a lower rotary block through-hole is provided on the wall of the lower rotary wiring clamping block that penetrates the inner side of the lower rotary wiring cavity. A fourth tapered groove for facilitating the winding of the wire is provided at the outer end of the lower rotary block through-hole. The lower rotary block through-hole coincides with the lateral projection of the lower wire end jack. One end of the lower rotary wiring clamping block close to the lower wire end fixing block is installed with a lower semi-circular rotary block. A lower semi-circular anti-disengagement block is fixedly installed on the inner side of the outer end of the lower semi-circular rotary block. The lower semi-circular rotary block is rotatably installed in the lower semi-circular rotary guide groove. At the same time, the lower semi-circular anti-disengagement block is rotatably installed in the lower semi-circular rotary guide anti-disengagement groove. The lower rotary wiring cavities on both sides of the bottom correspond one by one to the upper rotary wiring cavities that are divided into two parts above, and they are coaxial and have the same radius.

[0011] Further, the upper rotary wiring clamping block is provided with a cylindrical lock groove with an opening facing one side end. Above the cylindrical lock groove, there is an upper through groove with a longitudinal width smaller than the diameter. A plurality of groups of positioning holes are annularly arranged on one side surface of the upper wire end fixing block and the lower wire end fixing block included in the wire positioning mechanism facing the opening end of the cylindrical lock groove. And the ring formed by the rotation of the cylindrical lock groove coincides with the ring formed by the plurality of groups of positioning holes. At the same time, the positioning holes have the same diameter as the cylindrical lock groove, and inner anti-slip threads are provided in the positioning holes.

[0012] Furthermore, an anti-rotation limiting mechanism for preventing rotation after the wiring is completed is installed in the cylindrical lock groove. The anti-rotation limiting mechanism includes a limiting lock bar and a telescopic pushing block.

[0013] Furthermore, the limiting lock bar is installed in the cylindrical lock groove. The bottom of the telescopic pushing block is fixed to the top of the inner side end of the limiting lock bar. At the same time, the telescopic pushing block extends out of the upper rotary wiring clamping block through the upper through groove. Outer anti-slip threads are provided at the outer end of the limiting lock bar.

[0014] Another object of the present invention is to provide a working method of a shock-absorbing clamping device for a power equipment wiring terminal, which includes the following steps:

[0015] S1. Insert one of the two wires to be connected into the left upper wire end jack, the upper rotary block through-hole, and the right upper wire end jack in sequence.

[0016] S2. Insert the second wire to be connected into the left lower wire end jack, two groups of lower rotary block through-holes, and the right lower wire end jack in sequence. The first wire to be connected and the second wire to be connected can be inserted into the device in the reverse direction, but it is necessary to ensure that the insertion directions of the two wires are opposite.

[0017] S3. After the waiting connection line is inserted completely, rotate the upper rotating connection clamping block to drive the two groups of lower rotating connection clamping blocks below to rotate together;

[0018] S4. During the rotation process, the upper rotating block through-hole and the through-holes of the two groups of connected lower rotating blocks drive the line to wind. Since each through-hole is provided with a tapered groove, it can avoid abrasion of the line. At the same time, when rotating, hold the waiting connection line and control the wire inlet speed at both ends of the device to ensure that strong two groups of winding wire bodies are formed in the upper rotating connection cavity and the two lower rotating connection cavities on both sides, greatly improving the stability of the connection;

[0019] S5. After the rotary connection is completed, push the telescopic push block to drive the limit lock bar to insert into the corresponding positioning hole to perform anti-rotation positioning on the rotary connection mechanism, greatly improving the seismic resistance of the connection device.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) In the present invention, by setting two groups of symmetrical C-shaped frames and symmetrically installing line positioning mechanisms for installing and positioning two waiting connection ends on the inner sides of both ends of the C-shaped frame, the line positioning mechanism increases the accuracy of the connection. The line positioning mechanism includes an upper end fixed installation block and a lower end fixed installation block that can be slidably installed, and has the characteristics of convenient installation and disassembly. At the same time, a rotary connection mechanism for rotating, winding and clamping the line is installed between the two groups of line positioning mechanisms. The cable is wound and connected through the rotary connection mechanism, greatly improving the stability of the connection. The rotary connection mechanism includes an upper rotary connection clamping block and two groups of symmetrically installed lower rotary connection clamping blocks. The upper rotary connection clamping block and the two groups of symmetrically installed lower rotary connection clamping blocks are provided with a connected upper rotary connection cavity and two lower rotary connection cavities. The upper rotary connection cavity is divided into two parts corresponding to one group of lower rotary connection cavities respectively. The upper rotary connection clamping block is provided with a rotary connection plate, and the rotary connection plate is provided with an upper rotary block through-hole. The lower rotary connection clamping block is provided with a lower rotary block through-hole. The upper rotary connection clamping block and the two groups of symmetrically installed lower rotary connection clamping blocks realize the formation of strong two groups of winding wire bodies in the upper rotary connection cavity and the two lower rotary connection cavities on both sides, ensuring the firmness of the winding connection. An anti-rotation limit mechanism for preventing rotation after the connection is completed is also installed on the rotary connection mechanism. The anti-rotation limit mechanism includes a limit lock bar and a telescopic push block. Pushing the telescopic push block drives the limit lock bar to insert into the corresponding positioning hole on the line positioning mechanism to achieve the effect of preventing rotation. The structure is simple and the operation is convenient.

[0033] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0034] As Figure 1-9 shown, a shock-absorbing clamping device for a power equipment terminal includes two groups of symmetrically installed C-shaped frames 23. The inner sides of the two ends of the two groups of C-shaped frames 23 are fixedly installed by bolting on the front and rear surfaces of two groups of symmetrically installed line positioning mechanisms for the installation and positioning of two terminals to be connected. The line positioning mechanism includes an upper terminal fixed installation block 1 and a lower terminal fixed installation block 7 that can be slidably installed. At the same time, a rotary wiring mechanism for winding and clamping the line is installed between the two groups of line positioning mechanisms. The cable is wound and connected through the rotary wiring mechanism, which greatly improves the stability of the connection. An anti-rotation limit mechanism for preventing rotation after the connection is completed is also installed on the rotary wiring mechanism. The rotary wiring mechanism is composed of an upper rotary wiring clamping block 13 and two groups of symmetrically installed lower rotary wiring clamping blocks 20. The rotary wiring mechanism is positioned by the anti-rotation limit mechanism to prevent rotation, further improving the seismic resistance of the wiring device during wiring.

[0035] Principle of the shock-absorbing clamping device:

[0036] By setting two sets of symmetric C-shaped frames 23, and symmetrically installing wire positioning mechanisms for the installation and positioning of two wire ends to be connected at the inner sides of both ends of the C-shaped frame 23, the wire positioning mechanism improves the accuracy of wiring. The wire positioning mechanism includes an upper wire end fixed mounting block 1 and a lower wire end fixed mounting block 7 that can be slidably installed, which has the characteristics of convenient installation and disassembly. At the same time, a rotary wiring mechanism for rotary winding and clamping of the wire is installed between the two sets of wire positioning mechanisms. The rotary wiring mechanism includes an upper rotary wiring clamping block 13 and two sets of symmetrically installed lower rotary wiring clamping blocks 20. The upper rotary wiring clamping block 13 and the two sets of symmetrically installed lower rotary wiring clamping blocks 20 are provided with a communicating upper rotary wiring cavity 1301 and two lower rotary wiring cavities 2001. The upper rotary wiring cavity 1301 is divided into two parts corresponding to one set of lower rotary wiring cavities 2001 respectively. A rotary wiring plate 18 is arranged in the upper rotary wiring clamping block 13. An upper rotary block through hole 19 is arranged on the rotary wiring plate 18. A lower rotary block through hole 22 is arranged on the lower rotary wiring clamping block 20. By rotating the upper rotary wiring clamping block 13 and the two sets of symmetrically installed lower rotary wiring clamping blocks 20, two strong winding wire bodies are formed in the upper rotary wiring cavity 1301 and the two lower rotary wiring cavities 2001 on both sides, ensuring the firmness of the winding connection. A rotation prevention limiting mechanism for preventing rotation after wiring is installed on the rotary wiring mechanism. The rotation prevention limiting mechanism includes a limiting lock bar 15 and a telescopic pushing block 16. Pushing the telescopic pushing block 16 drives the limiting lock bar 15 to insert into the corresponding positioning hole 12 on the wire positioning mechanism to achieve the effect of preventing rotation. The structure is simple, the operation is convenient, and the rotation is prevented, further improving the seismic resistance of the wiring of the wiring device.

[0037] As Figure 3 、 4 shown, a through upper wire end jack 2 is horizontally arranged in the upper wire end fixed mounting block 1. At the same time, a first tapered groove 201 for facilitating wire winding is arranged at one end of the upper wire end jack 2 close to the transfer wiring mechanism. One end of the upper wire end fixed mounting block 1 close to the transfer wiring mechanism is provided with an upper semi-circular rotary guide rail groove 4. The upper semi-circular rotary guide rail groove 4 is located at the bottom of the upper wire end fixed mounting block 1 and communicates with a concentric upper semi-circular rotary guide rail anti-drop groove 3. Side grooves 5 are symmetrically arranged at the bottoms of the front and rear surfaces of the upper wire end fixed mounting block 1. A sliding guide rail 6 is installed in the side grooves 5. The upper wire end fixed mounting block 1 is slidably installed on the top of the lower wire end fixed mounting block 7 through the symmetrically arranged sliding guide rails 6 at the front and rear. The setting of the first tapered groove 201 avoids wear of the depression during the process of winding the wire, and at the same time can increase the wire corner and improve the bonding strength.

[0038] As Figure 3 、 5As shown in the figure, guide rail blocks 11 are symmetrically arranged at the front and back of the top of the lower wire end fixed mounting block 7. The sliding guide rails 6 arranged at the front and back of the bottom of the upper wire end fixed mounting block 1 are slidably mounted on the guide rail blocks 11, and the bottom surface of the upper wire end fixed mounting block 1 is fitted and mounted with the top surface of the lower wire end fixed mounting block 7. A through lower wire end jack 8 is horizontally arranged in the lower wire end fixed mounting block 7. A second tapered groove 801 for facilitating wire winding is arranged at one end of the lower wire end jack 8 close to the patch cord mechanism. A lower semi-circular rotary guide rail groove 9 is arranged on one side surface of the lower wire end fixed mounting block 7 outside the second tapered groove 801. The lower semi-circular rotary guide rail groove 9 communicates with a concentric lower semi-circular rotary guide rail anti-disengagement groove 10 at the inner bottom of the lower wire end fixed mounting block 7. And the upper semi-circular rotary guide rail groove 4 is concentric with the lower semi-circular rotary guide rail groove 9 and has the same horizontal depth. By providing the sliding guide rails 6 and the guide rail blocks 11, the upper wire end fixed mounting block 1 and the lower wire end fixed mounting block 7 can be easily installed together, and the installation and disassembly are convenient to operate. At the same time, the upper semi-circular rotary guide rail groove 4 being concentric with the lower semi-circular rotary guide rail groove 9 and having the same horizontal depth can also provide trajectory limitation for the rotation of the rotary block.

[0039] As Figure 2-7 As shown in the figure, upper semi-circular rotary blocks 17 are symmetrically installed at the left and right ends of the upper rotary patch cord clamping block 13. Upper semi-circular anti-disengagement blocks 1701 are installed on the outer ends of the upper semi-circular rotary blocks 17 towards the inside. The upper semi-circular rotary blocks 17 at both ends are rotatably installed in the upper semi-circular rotary guide rail grooves 4 inside the upper wire end fixed mounting blocks 1 installed on both sides of the upper rotary patch cord clamping block 13. At the same time, the upper semi-circular anti-disengagement blocks 1701 are rotatably installed in the upper semi-circular rotary guide rail anti-disengagement grooves 3. A semi-cylindrical upper rotary patch cord cavity 1301 with openings towards both ends and the bottom is arranged inside the upper rotary patch cord clamping block 13. A rotary patch cord plate 18 with a flush bottom surface is arranged in the middle of the upper rotary patch cord cavity 1301. Upper rotary block through holes 19 that coincide with the horizontal projections of the upper wire end jacks 2 are arranged on the rotary patch cord plate 18. Third tapered grooves 1901 for facilitating wire winding are symmetrically arranged at both ends of the upper rotary block through holes 19. Lower rotary patch cord clamping blocks 20 with a horizontal width half of that of the upper rotary patch cord clamping block 13 and the same longitudinal width are symmetrically installed at the bottom of the upper rotary patch cord clamping block 13. The upper rotary patch cord clamping block 13 can freely rotate in the upper semi-circular rotary guide rail grooves 4 and the lower semi-circular rotary guide rail grooves 9 through the upper semi-circular rotary blocks 17 and the upper semi-circular anti-disengagement blocks 1701 symmetrically arranged at both ends and will not fall off, increasing the structural stability.

[0040] As Figure 5-8As shown in the figure, the lower rotating wiring clamping block 20 is provided with a lower rotating wiring cavity 2001 with an opening facing upward and laterally outward. At the same time, a lower rotating block through-hole 22 is provided on the wall of the lower rotating wiring clamping block 20 that penetrates the inner side of the lower rotating wiring cavity 2001. A fourth conical groove 2201 that is conducive to winding the wire is provided at the outer end of the lower rotating block through-hole 22. The lateral projection of the lower rotating block through-hole 22 coincides with the lower wire end jack 8. One end of the lower rotating wiring clamping block 20 close to the lower wire end fixed mounting block 7 is installed with a lower semi-circular rotating block 21. A lower semi-circular anti-disengagement block 2101 is fixedly installed on the inner side of the outer end of the lower semi-circular rotating block 21. The lower semi-circular rotating block 21 is rotatably installed in the lower semi-circular rotating guide groove 9. At the same time, the lower semi-circular anti-disengagement block 2101 is rotatably installed in the lower semi-circular rotating guide anti-disengagement groove 10. The lower rotating wiring cavities 2001 on both sides of the bottom correspond one by one to the upper rotating wiring cavities 1301 that are divided into two parts above, and at the same time, they have the same axis and radius. The lower rotating wiring clamping block 20 can freely rotate in the upper semi-circular rotating guide groove 4 and the lower semi-circular rotating guide groove 9 through the lower semi-circular rotating block 21 and the lower semi-circular anti-disengagement block 2101 provided at the outer end, and the structure is stable.

[0041] As Figure 6-8 shown in the figure, the upper rotating wiring clamping block 13 is provided with a cylindrical locking groove 14 with an opening facing one end. Above the cylindrical locking groove 14, there is an upper through groove 1401 with a longitudinal width smaller than the diameter. A plurality of groups of positioning holes 12 are annularly provided on one side surface of the upper wire end fixed mounting block 1 and the lower wire end fixed mounting block 7 facing the opening end of the cylindrical locking groove 14. And the ring formed by the rotation of the cylindrical locking groove 14 coincides with the ring formed by the plurality of groups of positioning holes 12. At the same time, the positioning holes 12 have the same diameter as the cylindrical locking groove 14. Inner anti-slip threads 1201 are provided in the positioning holes 12 to ensure that one opening of the cylindrical locking groove 14 coincides with the central circular track of the positioning holes 12 during the rotation process, facilitating the insertion of the anti-rotation limiting mechanism.

[0042] As Figure 8 shown in the figure, an anti-rotation limiting mechanism for preventing rotation after the wiring is completed is installed in the cylindrical locking groove 14. The anti-rotation limiting mechanism includes a limiting lock bar 15 and a telescopic push block 16. The top of the telescopic push block 16 is provided with wavy lines or other structures to increase the friction coefficient, facilitating the control by personnel pushing.

[0043] As Figure 5 、 8As shown in the figure, the limit lock bar 15 is installed in the cylindrical lock groove 14. The bottom of the telescopic push block 16 is fixed to the top of the inner side end of the limit lock bar 15. At the same time, the telescopic push block 16 extends out of the upper rotary wiring clamping block 13 through the upper through groove 1401. The outer side end of the limit lock bar 15 is provided with an outer anti-slip pattern 1501. By pushing the limit lock bar 15 into the positioning hole 12, the outer anti-slip pattern 1501 contacts the inner anti-slip pattern 1201, preventing the limit lock bar 15 from moving and disengaging from the limit function, and increasing the reliability of the limit.

[0044] The working method of a shock-absorbing clamping device for a power equipment wiring terminal proposed by the present invention includes the following steps:

[0045] S1. Insert one of the two wires to be connected into the left upper line end jack 2, the upper rotary block through hole 19, and the right upper line end jack 2 in sequence.

[0046] S2. Insert the second wire to be connected into the left lower line end jack 8, the two groups of lower rotary block through holes 22, and the right lower line end jack 8 in sequence. The first wire to be connected and the second wire to be connected can be inserted into the device in the reverse direction, but it is necessary to ensure that the insertion directions of the two wires are opposite.

[0047] S3. After the wires to be connected are inserted, rotate the upper rotary wiring clamping block 13 to drive the two groups of lower rotary wiring clamping blocks 20 below to rotate together.

[0048] S4. During the rotation process, the upper rotary block through hole 19 and the two groups of connected lower rotary block through holes 22 drive the wires to wind. Since each wire hole is provided with a tapered groove, it is possible to avoid abrasion of the wires. At the same time, when rotating, the wires to be connected are pulled, and the wire inlet speed at both ends of the device is controlled to ensure that strong two groups of winding wire bodies are formed in the upper rotary wiring cavity 1301 and the two side lower rotary wiring cavities 2001, greatly improving the stability of the wiring.

[0049] S5. After the wiring is completed by rotation, the telescopic push block 16 is pushed to drive the limit lock bar 15 to insert into the corresponding positioning hole 12 to perform anti-rotation positioning on the rotary wiring mechanism, greatly improving the seismic resistance of the wiring device.

[0050] When disassembling the shock-absorbing clamping device, first remove the C-shaped frame 23, then adjust the upper rotary wiring clamping block 13 to the top, and the two groups of lower rotary wiring clamping blocks 20 are at the bottom. Pull the fixed mounting blocks 7 at both sides of the lower line end to move outward. The fixed mounting blocks 7 at the lower line end drive the lower rotary wiring clamping blocks 20 to move outward. Then, the upper line end fixed mounting block 1 is rotated to disengage from the upper rotary wiring clamping block 13, and the lower line end fixed mounting block 7 is rotated to disengage from the lower rotary wiring clamping block 20. Just operate in reverse order of the installation steps.

[0051] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention.
