Description

Technical Field

[0001] The utility model relates to the technical field of electric power operation and maintenance, and in particular to a high-voltage line insulator crushing device. Background Art

[0002] High-voltage line insulators are devices made of special insulating materials. They are mainly used in high-voltage and ultra-high-voltage overhead transmission lines and substations in power transmission systems. Their core function is to provide electrical insulation between wires and poles or towers to ensure that current only flows along the wires and does not leak to the ground or other conductors, thereby ensuring the safe operation of the power system and the safety of personnel.

[0003] During the maintenance of high-voltage lines, insulators are exposed to the natural environment for a long time and are easily damaged by natural factors such as wind, rain, and lightning. When the insulator is seriously damaged, it needs to be replaced. In this process, the operator usually uses handheld tools to knock on the insulator to break it. This crushing method requires a lot of physical strength, the operator's work intensity is high, and there is a risk of handheld tools slipping, which poses a high safety risk. In addition, the material of the insulator is usually hard ceramic or glass, which is difficult to crush, the crushing efficiency is low, and splashing is easy to occur during the crushing process, causing harm to the operator. Therefore, it is particularly important to develop a device that can quickly and safely crush insulators. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides a high-voltage line insulator breaking device, which solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A high-voltage line insulator crushing device comprises a corner connecting rod, which is a blunt-angle bending structure. A crushing head is fixedly provided at the front end of the corner connecting rod, and an extension rod is welded and fixed to the rear end of the crushing head. A handle rod is sleeved on the extension rod, and a contraction groove is provided inside the handle rod. The extension rod is movably arranged in the contraction groove. A long screw is provided inside the handle rod, and the upper end of the long screw extends out from the top of the handle rod. A knob is fixedly provided at the upper end of the long screw, and a threaded hole is provided inside the extension rod. The long screw is screwed to the extension rod through the threaded hole. A circle of rotating clamping plate is fixedly provided on the long screw between the knob and the handle rod, and a protective cover is sleeved on the outer side of the rotating clamping plate. The rotating clamping plate is rotatably connected to the protective cover, and the protective cover is fixedly connected to the handle rod through screws.

[0007] Furthermore, the crushing head is composed of an upper jaw plate, a lower jaw plate, a limiting support rod, an adjusting bolt and a fixing rod. The right end of the fixing rod is welded to the front end of the corner connecting rod, and the lower side of the left end of the fixing rod is welded to the lower jaw plate. A movable upper jaw plate is symmetrically arranged on the upper side of the lower jaw plate. The limiting support rod passes through the interior of the upper jaw plate, and the lower end of the limiting support rod is fixedly connected to the lower jaw plate. The interior of the upper jaw plate is threaded with an adjusting bolt, and the lower end of the adjusting bolt is embedded in the interior of the fixing rod and is rotatably connected to it.

[0008] Furthermore, a PVC transparent protective cover with a cone-shaped structure is sleeved on the fixing rod, and its opening faces the left side.

[0009] Furthermore, an inclined reinforcing rib plate is welded on the inner side of the corner connecting rod.

[0010] Furthermore, a non-slip grip cover made of rubber is sleeved on the upper side of the handlebar ring surface.

[0011] Furthermore, limit blocks are fixed on the upper and lower sides of the extension rod ring surface near the right end, and limit slide grooves are opened on the upper and lower sides of the handle rod ring surface, and the limit slide grooves are connected with the contraction grooves, and the limit blocks extend from the limit slide grooves.

[0012] Furthermore, a hanging ring is fixedly provided on the outer end surface of the knob.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model adopts a corner bending structure as a whole, and uses the principle of mechanics to help provide a better mechanical angle and a more convenient operation method during the crushing process, facilitate force application, and improve the convenience of crushing the insulator. At the same time, the upper jaw plate and the lower jaw plate are used to form a clamping structure for the insulator, which is convenient for quickly crushing the insulator, reducing the difficulty of operation and effectively reducing the physical exertion of the operator.

[0015] 2. The utility model can clamp onto the insulator through the crushing head, and the insulator can be crushed by the joint action of the upper jaw plate and the lower jaw plate when force is applied. At the same time, the position of the upper jaw plate can be adjusted by the adjusting bolt, which is convenient for adjusting the distance between the upper jaw plate and the lower jaw plate, and can be suitable for insulators of different thicknesses. When crushing the insulator, the operator first adjusts the distance between the upper jaw plate and the lower jaw plate by rotating the adjusting bolt to adapt to the insulator to be crushed. Then, the crushing head is clamped onto the insulator, and force is applied through the handle bar to make the upper jaw plate and the lower jaw plate clamp and crush the insulator. Since the upper jaw plate is movable, it can be adaptively adjusted according to the shape and size of the insulator to ensure uniform and efficient crushing effect.

[0016] 3. A cone-shaped transparent PVC protective cover is set on the fixed rod, and its opening faces the left. The main function of the protective cover is to prevent the debris, dust or other splashes generated during the crushing process from causing harm to the operator. The use of PVC transparent material allows the operator to clearly observe the crushing process, thereby more accurately controlling the crushing force and position.

[0017] 4. The upper side of the handlebar ring is covered with a rubber anti-skid grip. The rubber anti-skid grip has good friction, which can greatly increase the stability of the operator when holding the handlebar, improve the protection performance, and reduce operational errors caused by hand sliding, thereby reducing the risk of accidents.

[0018] 5. The coordinated use of the limit block and the limit slot ensures the stable sliding of the extension rod in the handle bar. When the length of the extension rod needs to be adjusted, the limit block will move along the limit slot to maintain the linearity and stability of the extension rod during the sliding process. At the same time, it effectively prevents the extension rod from rotating in the handle bar, ensuring that the force can be transmitted along a straight line when the crushing device is used, thereby improving work efficiency and safety. In addition, the design of the limit block also plays a limiting role, that is, when the extension rod is fully retracted or extended to the maximum length, the limit block will reach the end of the limit slot, thereby preventing the extension rod from moving further, avoiding damage to the device or inconvenience in operation caused by excessive stretching or contraction.

[0019] 6. A hanging ring is fixed on the outer end surface of the knob, which is convenient for the operator to connect the device with an external sling, so that the device can be conveniently hung on a tool bag, work belt or other equipment, making it easy to carry and preventing the device from accidentally falling during high-altitude operations.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] like Figures 1 to 5 As shown, a high-voltage line insulator crushing device includes a corner connecting rod 2, the corner connecting rod 2 is an obtuse-angle bending structure, a crushing head 1 is fixedly arranged at the front end of the corner connecting rod 2, an extension rod 5 is welded and fixedly arranged at the rear end of the crushing head 1, a handle rod 4 is sleeved on the extension rod 5, a contraction groove 13 is opened inside the handle rod 4, the extension rod 5 is movably arranged in the contraction groove 13, a long screw rod 11 is arranged inside the handle rod 4, and the upper end of the long screw rod 11 extends from the top end of the handle rod 4, a knob 9 is fixedly arranged at the upper end of the long screw rod 11, and a handle rod 4 is opened inside the extension rod 5. There is a threaded hole 12, and the long screw 11 is screwed to the extension rod 5 through the threaded hole 12. A circle of rotating clamping plate 15 is fixed on the long screw 11 between the knob 9 and the handle rod 4. A protective cover 14 is sleeved on the outer side of the rotating clamping plate 15. The rotating clamping plate 15 is rotatably connected to the protective cover 14, and the protective cover 14 is fixedly connected to the handle rod 4 through screws. This design solves the problem that the crushing method of knocking the insulator by hand-held tools requires a lot of physical strength, the work intensity of the operator is high, and the hand-held tool has the risk of slipping, and the safety risk is high. In addition, the material of the insulator is usually hard ceramic or glass, which is difficult to crush, the crushing efficiency is low, and splashing is easy to occur during the crushing process, causing harm to the operator.

[0029] The crushing head 1 is composed of an upper jaw plate 1.2, a lower jaw plate 1.3, a limit support rod 1.4, an adjusting bolt 1.5 and a fixing rod 1.6. The right end of the fixing rod 1.6 is welded to the front end of the corner connecting rod 2. The lower side of the left end of the fixing rod 1.6 is welded to the lower jaw plate 1.3. A movable upper jaw plate 1.2 is symmetrically arranged on the upper side of the lower jaw plate 1.3. The upper jaw plate 1.2 is penetrated by the limit support rod 1.4, and the lower end of the limit support rod 1.4 is fixedly connected to the lower jaw plate 1.3. The upper jaw plate 1.2 is screwed with an adjusting bolt 1.5, and the lower end of the adjusting bolt 1.5 is embedded in the fixing rod 1.6 and rotatably connected thereto. The crushing head 1 can be clamped on the insulator by the arrangement of the design. When force is applied, the insulator is crushed by the joint action of the upper jaw plate 1.2 and the lower jaw plate 1.3. At the same time, the position of the upper jaw plate 1.2 can be adjusted by the setting of the adjusting bolt 1.5, so as to adjust the distance between the upper jaw plate 1.2 and the lower jaw plate 1.3, and can be suitable for insulators of different thicknesses. When crushing the insulator, the operator first adjusts the distance between the upper jaw plate 1.2 and the lower jaw plate 1.3 by rotating the adjusting bolt 1.5 to adapt to the insulator to be crushed. Then, the crushing head 1 is clamped onto the insulator, and the upper jaw plate 1.2 and the lower jaw plate 1.3 are used to clamp and crush the insulator by applying force through the handle bar 4. Since the upper jaw plate 1.2 is movable, it can be adaptively adjusted according to the shape and size of the insulator to ensure uniform and efficient crushing effect.

[0030] A conical PVC transparent protective cover 1.1 is set on the fixed rod 1.6, and its opening faces the left side. The main function of the protective cover is to prevent the debris, dust or other splashes generated during the crushing process from causing harm to the operator. The use of PVC transparent material makes it convenient for the operator to clearly observe the crushing process, so as to more accurately control the crushing force and position.

[0031] An inclined reinforcing rib plate 3 is welded to the inner side of the corner connecting rod 2. The reinforcing rib plate 3 can effectively increase the load-bearing capacity and bending strength of the connecting rod, thereby preventing the connecting rod from bending or breaking.

[0032] The upper side of the ring surface of the handle bar 4 is covered with a rubber anti-skid grip 8. The rubber anti-skid grip 8 has good friction, which can greatly increase the stability of the operator when holding the handle bar 4, improve the protection performance, and reduce the operating errors caused by hand sliding, thereby reducing the risk of accidents.

[0033] The upper and lower sides of the ring surface of the extension rod 5 near the right end are fixed with limit blocks 7, and the upper and lower sides of the ring surface of the handle rod 4 are provided with limit slots 6, and the limit slots 6 are connected with the contraction slots 13, and the limit blocks 7 extend from the limit slots 6. The use of the limit blocks 7 and the limit slots 6 ensures the stable sliding of the extension rod 5 in the handle rod 4. When the length of the extension rod 5 needs to be adjusted, the limit blocks 7 will move along the limit slots 6, so as to maintain the linearity and stability of the extension rod 5 during the sliding process. At the same time, the extension rod 5 is effectively prevented from rotating in the handle rod 4, ensuring that the force can be transmitted along a straight line when the crushing device is used, thereby improving the work efficiency and safety. In addition, the design of the limit blocks 7 also plays a role of limiting, that is, when the extension rod 5 is fully contracted or stretched to the maximum length, the limit blocks 7 will reach the end of the limit slots 6, thereby preventing the extension rod 5 from further moving, avoiding damage to the device or inconvenience in operation caused by excessive stretching or contraction.

[0034] A hanging ring 10 is fixedly provided on the outer end surface of the knob 9, and the hanging ring 10 is convenient for the operator to connect the device to an external sling, so that the device can be conveniently hung on a tool bag, a work belt or other equipment, thereby facilitating carrying and preventing the device from accidentally falling during high-altitude operations.

[0035] The working principle of the high-voltage line insulator crushing device is as follows: in actual use, the operator connects to the lifting ring at the tail of the device through an external lifting rope to achieve the connection of the device to prevent the device from accidentally falling during operation. Rotate the knob 9, drive the long screw 11 to rotate through the knob 9, drive the extension to move through the rotation of the long screw 11, adjust the length of the extension rod 5, and make the overall length of the extension rod 5 and the handle rod 4 suitable for the current working environment and operation requirements. Then the operator rotates the adjustment bolt 1.5 to adjust the distance between the upper jaw plate 1.2 and the lower jaw plate 1.3 to adapt to the thickness of the insulator to be crushed. Align the crushing head 1 with the insulator so that the insulator is stuck between the upper jaw plate 1.2 and the lower jaw plate 1.3, and apply force through the handle rod 4 so that the crushing head 1 clamps the insulator. As the force increases, the upper jaw plate 1.2 and the lower jaw plate 1.3 work together to crush the insulator. During the crushing process, the cone-shaped PVC transparent protective cover 1.1 can effectively block the fragments and splashes of the insulator and protect the operator from injury.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
