Description

Technical Field

[0001] This application relates to the field of power construction technology, and in particular to a power construction safety device. Background Technology

[0002] Safety equipment for power construction is a core protective device used during power grid transmission and transformation engineering construction and power outage maintenance to reliably ground out power equipment or lines and ensure the safety of workers. When installing high-voltage grounding wires, it is usually necessary to connect the conductor end clamp at the top of the operating rod to the live conductor being maintained (such as a conductor or busbar), and manually tighten the clamp using a spiral structure to ensure reliable grounding circuit continuity. Common spiral grounding wires mainly consist of an epoxy resin insulated operating rod, a conductor end clamp, and a rotating handle at the tail. During operation, the worker holds the operating rod steady with one hand and rotates the handle with the other, causing the insulated rod to rotate and thus tighten the clamp.

[0003] However, the above-mentioned device has obvious shortcomings in actual operation. Due to the low coefficient of friction between the insulating gloves and the operating rod surface, it is very easy to slip when rotating the handle while wearing gloves; at the same time, the grounding wire itself is relatively thick and heavy, especially when installing the grounding wire at height. The operator needs to overcome great resistance to continuously rotate the insulating rod, which is not only laborious, but also makes it difficult to ensure that the wire clamp is tightened in place, resulting in an unstable grounding connection and potential safety hazards such as detachment or poor contact.

[0004] Therefore, there is a need to provide a safety device for power construction. Summary of the Invention

[0005] To address the problem that existing power construction safety devices require manual rotation of the handle, which is both laborious and makes it difficult to ensure a secure connection, this application provides a power construction safety device.

[0006] This application provides a power construction safety device, which adopts the following technical solution: it includes a grounding clamp, a connecting wire, a wiring clamp, an insulating rod, and a driving assembly. The grounding clamp includes a grounding hook, a grounding block, and a grounding bolt. The grounding hook has a limiting groove and a grounding screw hole. One end of the grounding block is inserted into the limiting groove and can slide along the limiting groove. The grounding bolt is screwed to the grounding screw hole, and the screw end of the grounding bolt passes through the grounding screw hole and is rotatably connected to the grounding block, and can drive the grounding block to move closer to or away from the hook tip of the grounding hook. The wiring pliers include a wiring hook, a wiring block, and a wiring rod. The wiring hook has a limiting groove and a wiring hole. One end of the wiring block is inserted into the limiting groove and can slide along the limiting groove. One end of the wiring rod passes through the wiring hole and is connected to the wiring block. The wiring hook is electrically connected to the grounding hook via the connecting wire; One end of the insulating rod is connected to the wiring hook; The drive assembly is connected to the connector rod and can drive the connector rod to move the connector block closer to or away from the hook tip of the connector hook.

[0007] By adopting the above technical solution, the grounding block of the grounding clamp can slide within the limiting groove of the grounding bolt to approach or move away from the tip of the grounding hook, achieving a secure grounding. Similarly, the wiring block of the wiring clamp can slide within the limiting groove of the wiring rod to approach or move away from the tip of the wiring hook, facilitating connection to the de-energized conductor. Simultaneously, the drive assembly can drive the wiring rod to move the wiring block, eliminating the need for manual rotation. Compared to existing technologies that require workers to manually rotate the handle to tighten the clamp, this avoids the slippage problem when rotating the handle while wearing insulated gloves. Furthermore, it eliminates the need for operators to continuously rotate the insulating rod against significant resistance, saving effort and ensuring the clamp is securely tightened, resulting in a firm grounding connection and reducing the safety hazards of detachment or poor contact.

[0008] Specifically, the drive assembly includes an inner rod and a drive member. The insulating rod has a receiving cavity inside. The cavity wall has a near hook hole and a far hook hole opposite each other along the axial direction of the insulating rod. The inner rod is rotatably connected in the receiving cavity, and the rotation axis of the inner rod and the central axis of the near hook hole are both coincident with the central axis of the far hook hole. The top end of the inner rod has a lifting screw hole, and the bottom end of the connecting rod has an external thread adapted to the lifting screw hole. The bottom end of the connecting rod passes through the near hook hole and is screwed into the lifting screw hole. The bottom end of the inner rod passes through the far hook hole and is connected to the drive member for transmission. The drive member can drive the inner rod to rotate. The groove wall of the limiting groove can abut against the connecting block and restrict the connecting block and the connecting rod from rotating with the inner rod.

[0009] By adopting the above technical solution, the driving component drives the inner rod to rotate. Since the bottom end of the connecting rod is screwed to the lifting screw hole at the top of the inner rod, and the wall of the limiting groove restricts the connecting block and the connecting rod from rotating with the inner rod, the rotation of the inner rod can cause the connecting rod to drive the connecting block to slide along the limiting groove, approaching or moving away from the hook tip of the connecting hook. This enables the connecting pliers to clamp and release the wire, avoiding the laborious and unstable problems of manual operation, and making the operation of power construction safety equipment more labor-saving, convenient and reliable.

[0010] Furthermore, the driving component includes a motor, a power supply component, and a control component. The bottom end of the inner rod is provided with a spline hole, and the output shaft of the motor is provided with a spline that matches the spline hole. The power supply component is electrically connected to the motor and can supply power to the motor. The control component is electrically connected to the motor and can drive the output shaft of the motor to rotate.

[0011] By adopting the above technical solution, the spline on the motor output shaft is adapted to the spline hole at the bottom of the inner rod. The power supply component delivers power to the motor, and the control component drives the motor output shaft to rotate, which causes the inner rod to rotate. This, in turn, drives the wiring rod to move the wiring block closer to or away from the hook tip of the wiring hook, avoiding the laborious and slippage problems of manual rotation. This realizes the automatic operation of power construction safety equipment, making wiring operations more labor-saving, convenient, and reliable.

[0012] Furthermore, the power supply component is a battery box, which has a battery compartment for accommodating batteries. The motor body is connected to the battery box and electrically connected to the batteries in the battery compartment.

[0013] By adopting the above technical solution and using a battery box as the power supply component, the battery compartment can hold batteries to power the motor, enabling the motor to operate independently without relying on an external power source. This improves the flexibility and convenience of using electrical construction safety equipment and allows it to adapt to different construction environments and scenarios.

[0014] Furthermore, the control component includes a clamping control button and a releasing control button. Both the clamping control button and the releasing control button are located on the battery box and are electrically connected to the motor. When the clamping control button is pressed, it can control the output shaft of the motor to drive the inner rod to rotate in the outward direction of the lifting screw hole. When the releasing control button is pressed, it can control the output shaft of the motor to drive the inner rod to rotate in the inward direction of the lifting screw hole.

[0015] By adopting the above technical solution, a clamping control button and a releasing control button are set on the battery box and electrically connected to the motor. The user can press the clamping control button to drive the motor output shaft to rotate the inner rod in the direction of rotation of the lifting screw hole, which will drive the terminal block to approach the hook tip of the terminal hook, thereby achieving rapid clamping of the wire. Pressing the releasing control button will drive the motor output shaft to rotate the inner rod in the direction of rotation of the lifting screw hole, which will drive the terminal block away from the hook tip of the terminal hook, thereby achieving rapid release of the wire. The operation is simple and improves the convenience and efficiency of using safety equipment for power construction.

[0016] Furthermore, the control unit also includes an overload protector connected in series in the circuit between the motor and the battery. When the terminal block approaches the tip of the terminal hook and the wire to be clamped is pressed between the terminal block and the terminal hook, and the load on the motor increases, the overload protector can disconnect the circuit between the motor and the battery to shut down the motor.

[0017] By adopting the above technical solution, when the terminal block approaches the tip of the terminal hook and the wire to be clamped is pressed between the terminal block and the terminal hook, the motor load will increase. At this time, the overload protector can cut off the circuit between the motor and the battery to shut down the motor, avoid damage to the motor due to overload, extend the service life of the motor, and at the same time prevent damage to the wire due to excessive clamping, ensuring the normal use of power construction safety equipment and the safe connection of the wire.

[0018] Specifically, the hook tip of the wire hook has a wire-receiving groove, and the middle part of the wire-receiving groove is recessed away from the insulating rod.

[0019] By adopting the above technical solution, the wire-receiving groove opened at the tip of the connector hook can accommodate the wire, and the middle of the wire-receiving groove is recessed away from the insulating rod, which can better fit the wire, prevent the wire from slipping off the connector hook, and make the connection more secure.

[0020] Furthermore, the driving component includes a mounting box, a handle, a driven shaft, and a tightening spline shaft. A connecting hole leading to the interior of the mounting box is provided on one side. The mounting shaft is housed within the mounting box. The handle has a wide end and a narrow end, respectively. The narrow end is rotatably connected to the mounting shaft. An arc-shaped rack is formed around the mounting shaft on the wide end. A tightening hole is provided on the inner wall of the mounting box along the length of the mounting shaft. The driven shaft is rotatably connected within the mounting box. A driven gear is fitted onto the driven shaft, meshing with the arc-shaped rack. One end of the driven shaft passes through the tightening hole and connects to the tightening spline shaft. The bottom end of the inner rod has a spline hole adapted to the tightening spline shaft and can be fitted onto the tightening spline shaft via the spline hole for keyed connection.

[0021] By adopting the above technical solution, when the operator operates the handle, the arc-shaped rack at the wide end of the handle will drive the driven gear to rotate, the driven gear will drive the driven shaft to rotate, and the driven shaft will then drive the inner rod to rotate through the tightened spline shaft, thereby driving the connecting rod to move the connecting block closer to or away from the hook tip of the connecting hook. This realizes a manual driving method for moving the connecting block, which allows the operator to flexibly control the position of the connecting block according to the actual situation. It avoids the problems of slippage, laborious operation, and difficulty in ensuring a firm connection when manually rotating the insulating rod, making the power construction safety equipment more labor-saving, convenient, and reliable during operation.

[0022] Furthermore, the drive element also includes a torsion spring disposed on the mounting shaft, which is capable of applying a force to the handle to drive the side of the handle away from the interior of the mounting box away from the interior of the mounting box.

[0023] By adopting the above technical solution and setting a torsion spring on the mounting shaft, the side of the handle away from the inside of the mounting box can automatically rotate away from the inside of the mounting box when no external force is applied. This makes it easier for the operator to operate the handle, improves the convenience and efficiency of operation, and helps to restore the handle to its initial position, preparing it for the next operation.

[0024] Furthermore, the drive component also includes a one-way bearing and a loosening spline shaft adapted to the spline hole. The one-way bearing is disposed between the driven gear and the driven shaft. The tightening hole and the loosening hole are respectively opened on the inner wall of the mounting box along the length direction of the mounting shaft. The end of the driven shaft away from the tightening hole passes through the loosening hole and is connected to the loosening spline shaft. When the handle is rotated around the mounting shaft to the inside of the mounting box on the side away from the mounting box, the inner and outer rings of the one-way bearing are locked together, and the tightening spline shaft can drive the inner rod keyed to the tightening spline shaft to rotate in the outward direction of the lifting screw hole. The loosening spline shaft can drive the inner rod keyed to the loosening spline shaft to rotate in the inward direction of the lifting screw hole. When the handle is rotated away from the inside of the mounting box on the side away from the mounting box around the mounting shaft, the inner and outer rings of the one-way bearing can rotate.

[0025] By adopting the above technical solution, since the tightening and loosening spline shafts are respectively located at both ends of the driven shaft, when the handle is rotated, the inner rod can be driven to rotate in the direction of screwing out or screwing in the lifting screw hole by tightening or loosening the spline shaft, thereby realizing the clamping and loosening action of the terminal block; and when the handle is rotated out of the mounting box, the inner and outer rings of the one-way bearing can rotate, so that the handle will quickly return to its original position after the user releases it, which improves the stability and reliability of the device operation and can better meet the needs of wiring and disconnection in power construction.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive assembly drives the connector rod to move the connector block closer to or away from the hook tip of the connector hook, achieving automatic fixing, reducing the rotational force, and solving the problem of slippage when rotating the handle while wearing gloves; 2. Using a drive assembly instead of manually rotating the insulating rod can overcome the resistance caused by the thick and heavy grounding wire, making wiring easier; 3. The drive assembly ensures a tight fit between the terminal block and the terminal hook, avoiding safety hazards such as loose grounding connection, detachment, or poor contact.

[0029] The following is in conjunction with the appendix Figure 1-7 Further explanation: See Figure 1 , Figure 2 and Figure 3In a first embodiment, a power construction safety device includes a drive assembly 5 and at least three grounding clamps 1, three connecting wires 2, three wiring clamps 3, and three insulating rods 4. Each of the grounding clamps 1, connecting wires 2, and wiring clamps 3 corresponds to one of the insulating rods 4. The grounding clamp 1 includes a grounding hook 11, a grounding block 12, and a grounding bolt 13. The grounding hook 11 has a limiting groove and a grounding screw hole on its hook body. One end of the grounding block 12 is inserted into the limiting groove and can slide along it. The grounding bolt 13 is screwed into the grounding screw hole, and the screw end of the grounding bolt 13 passes through the grounding screw hole and is rotatably connected to the grounding block 12, enabling the grounding block 12 to move closer to or away from the hook tip of the grounding hook 11. The wiring clamp 3 includes a wiring hook 31, a wiring block 32, and a wiring rod 33. The wiring hook 31 has a limiting groove and a wiring hole on its hook body. One end of the wiring block 32 is inserted into the limiting groove and can slide along it. One end of the wiring rod 33 passes through the wiring hole and is connected to the wiring block 32. The wiring hook 31 is connected via... Connecting wire 2 is electrically connected to grounding hook 11; one end of insulating rod 4 is connected to wiring hook 31; driving assembly 5 includes inner rod 51 and driving component 52, insulating rod 4 has a receiving cavity 41 inside, the cavity wall of receiving cavity 41 has a near hook hole and a far hook hole opposite to each other along the axial direction of insulating rod 4, inner rod 51 is rotatably connected in receiving cavity 41, and the rotation axis of inner rod 51 and the central axis of near hook hole are both coincident with the central axis of far hook hole, the top end of inner rod 51 has a lifting screw hole 511, and wiring rod 33... The bottom end is provided with an external thread that matches the lifting screw hole 511, and the bottom end of the connecting rod 33 passes through the near hook hole and is screwed into the lifting screw hole 511. The bottom end of the inner rod 51 passes through the far hook hole and is connected to the drive member 52 for transmission. The bottom end of the inner rod 51 is provided with a spline hole. The hook tip of the connecting hook 31 is provided with a wire receiving groove 311. The middle part of the wire receiving groove 311 is recessed in the direction away from the insulating rod 4 so that the connecting block 32 can abut the wire to be connected between the connecting block 32 and the groove wall of the wire receiving groove 311.

[0030] See Figure 2 and Figure 3The drive unit 52 includes a motor 521, a power supply unit 522, and a control unit 523. The output shaft of the motor 521 is provided with a spline that matches the spline hole. The power supply unit 522 is a battery box, which has a battery compartment 5221 for holding batteries. The motor 521 is connected to the battery box and electrically connected to the batteries in the battery compartment 5221 so that the batteries can supply power to the motor 521. The control unit 523 includes a clamping control button 5231, a releasing control button 5232, and an overload protector (not shown in the figure). The clamping control button 5231 and the releasing control button 5232 are both located on the battery box and are connected to the motor 521. 1. Electrical connection, and when the clamping control button 5231 is pressed, it can control the output shaft of the motor 521 to drive the inner rod 51 to rotate in the outward direction of the lifting screw hole 511. When the releasing control button 5232 is pressed, it can control the output shaft of the motor 521 to drive the inner rod 51 to rotate in the inward direction of the lifting screw hole 511. An overload protector is connected in series in the circuit between the motor 521 and the battery. When the terminal block 32 is close to the hook tip of the terminal hook 31 and the wire to be clamped is abutted between the terminal block 32 and the terminal hook 31, and the load of the motor 521 increases, the overload protector can cut off the circuit between the motor 521 and the battery to shut down the motor 521.

[0031] The working process of the first embodiment described in this application is as follows: First, the user can rotate the grounding bolt 13 to fix a grounding clamp 1 to a grounded conductor such as a grounding metal rod. Then, hold and lift the insulating rod 4 corresponding to the grounding clamp 1 until the wire to be connected is placed between the hook tip of the connector 31 and the connector block 32. Then, adjust the position of the connector 31 along the length of the wire until the connector 31 is directly above the exposed section of the wire where the insulation has been stripped off. Then, hold the insulating rod 4 with one hand and the battery box with the other hand, and connect the spline on the output shaft of the motor 521 to the spline hole at the bottom of the inner rod 51. Then, press the clamping control button 5231. At this time, the clamping control button 5231 will cause the output shaft of the motor 521 to drive the inner rod 51 to rise. The screw hole 511 rotates outward, causing the terminal block 32 to approach the hook tip of the terminal hook 31, thus quickly clamping the wire. After the wire is clamped, the load on the motor 521 increases and triggers the overload protector to shut down the motor 521. Then, the above operation is repeated to install terminal clamps 3 on multiple wires and ground the corresponding ground clamps 1. Compared with the existing technology, which requires workers to manually rotate the handle 525 to rotate the insulating rod 4 to tighten the wire clamp, this method avoids the problem of slippage when rotating the handle 525 while wearing insulating gloves. It also eliminates the need for operators to overcome significant resistance to continuously rotate the insulating rod 4, saving more effort and ensuring that the wire clamp is tightened in place, making the grounding connection firm and reducing the safety hazards of detachment or poor contact. After the operation is completed, the user can hold the insulating rod 4 with one hand and connect the spline on the output shaft of the motor 521 to the spline hole at the bottom of the inner rod 51 with the other hand. Then, press the release control button 5232. At this time, the release control button 5232 will cause the output shaft of the motor 521 to drive the inner rod 51 to rotate in the direction of screwing in the lifting screw hole 511, which will drive the terminal block 32 away from the hook tip of the terminal hook 31, thereby realizing the quick unlocking of the wire.

[0032] See Figure 4 , Figure 5 , Figure 6 and Figure 7 In the second embodiment, the drive assembly 5 includes a mounting box 524, a handle 525, a driven shaft 526, a torsion spring, a tightening spline shaft 527, a one-way bearing 529, and a loosening spline shaft 528 adapted to the spline hole. A communicating hole leading to the interior of the mounting box 524 is provided on one side of the mounting box 524. A mounting shaft 5241 is provided inside the mounting box 524. The handle 525 has a wide end and a narrow end, respectively. The narrow end is rotatably connected to the mounting shaft 5241, and an arc-shaped rack 5251 is formed around the mounting shaft 5241 on the wide end. A tightening hole is provided on the inner wall of the mounting box 524 along the length of the mounting shaft 5241. The driven shaft 526 is rotatably connected inside the mounting box 524. A driven gear 5261 is sleeved on the driven shaft 526, and the driven gear 5261 meshes with the arc-shaped rack 5251. One end of the driven shaft 526 passes through the tightening hole and is connected to the tightening spline shaft 527. The bottom end of the inner rod 51 has a spline hole that matches the tightening spline shaft 527, and can be sleeved on the tightening spline shaft 527 through the spline hole and keyed to the tightening spline shaft 527. A torsion spring is provided on... The mounting shaft 5241 is mounted on a handle 525, which is capable of applying a force to the handle 525 to rotate away from the interior of the mounting box 524. A one-way bearing 529 is disposed between the driven gear 5261 and the driven shaft 526. Tightening holes and loosening holes are provided opposite to each other on the inner wall of the mounting box 524 along the length of the mounting shaft 5241. The end of the driven shaft 526 away from the tightening hole passes through the loosening hole and connects to the loosening spline shaft 528. The handle 525 rotates around the mounting shaft 5241 on the side away from the mounting box 524. When the mounting box 524 is installed inside, the inner and outer rings of the one-way bearing 529 are locked together. Tightening the spline shaft 527 can drive the inner rod 51, which is keyed to the tightened spline shaft 527, to rotate in the outward direction of the lifting screw hole 511. Loosening the spline shaft 528 can drive the inner rod 51, which is keyed to the loosened spline shaft 528, to rotate in the inward direction of the lifting screw hole 511. When the handle 525 is rotated away from the mounting box 524 on the side away from the mounting box 524, the inner and outer rings of the one-way bearing 529 can rotate.

[0033] The implementation principle of the second embodiment described in this application is as follows: Since the tightening spline shaft 527 and the loosening spline shaft 528 are respectively located at both ends of the driven shaft 526, when the handle 525 rotates, the inner rod 51 can be driven to rotate in the direction of screwing out or screwing in the lifting screw hole 511 by tightening the spline shaft 527 or loosening the spline shaft 528, thereby realizing the clamping and loosening action of the terminal block 32; and when the handle 525 rotates away from the inside of the mounting box 524, the inner and outer rings of the one-way bearing 529 can rotate, and the torsion spring can make the side of the handle 525 away from the inside of the mounting box 524 automatically rotate away from the inside of the mounting box 524 when there is no external force, so that the handle 525 will quickly return to its original position after the user releases it, which improves the stability and reliability of the device operation and can better meet the needs of wiring and disconnection in power construction; compared with the electrical structure of the drive component 5 in the first embodiment, the second embodiment of this application adopts a pure mechanical structure, which has better insulation performance and stability, and a longer service life.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
