Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment for high-altitude operations, in particular to a safety guarantee device for high-altitude operations of a transformer substation with adaptive length. Background Art

[0002] Equipment and transmission lines in substations are responsible for power transmission, so they have limited fatigue resistance and need frequent maintenance. Equipment in substations is set up at high places, such as steel trusses. Operators must wear qualified safety equipment during operation to ensure that they can effectively prevent falling in the event of an accident.

[0003] The existing safety equipment is a double insurance wearable device. However, due to the special structure of the steel truss, the double insurance hook is fixed on the steel truss. When the operator moves, the double insurance hook will slide on the steel truss, which will cause wear on the insulating paint or surface coating on the steel truss, posing a safety hazard to subsequent power transmission. However, if the double insurance hook is fixed on the steel truss, the length of the safety rope attached to the insurance hook is certain, which will shorten the working range of the operator. For this reason, a safety device with adaptive length for high-altitude operations in substations is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a safety guarantee device with adaptive length for high-altitude operations in a substation, which solves the technical problems mentioned in the background technology.

[0006] The safety box is divided into a storage chamber and a driving chamber by a vertical partition. The adaptive storage assembly includes two sliding blocks arranged in the driving chamber, a limit plate located between the two sliding blocks, an elastic member located between the limit plate and the two sliding blocks, and a plurality of storage rods located on the sliding blocks and extending through the partition to the storage chamber. The storage rods are provided with guide wheels, and the safety ropes are interlaced and wound around the guide wheels. The vertical partitions are provided with sliding holes matching the storage rods.

[0007] Preferably, a guide rod is further provided between the limit plate and the two sliding blocks; and a guide through hole for cooperating with the guide rod is provided on the sliding block.

[0008] Preferably, the connection assembly includes a U-shaped connection plate, two arc-shaped clamping members rotatably arranged in the U-shaped connection plate, and an operating assembly driving the two arc-shaped clamping members to open and close;

A connecting buckle for cooperating with the connecting ring is provided on the safety protection box, and the connecting buckle and the connecting ring are fixedly connected by a connecting bolt.

[0010] Preferably, the operating assembly includes a lead screw rotatably arranged in the U-shaped connecting plate, a driving block slidably arranged in the U-shaped connecting plate, and two arc-shaped rods rotatably arranged on both sides of the driving block;

[0011] An internal threaded hole for cooperating with the lead screw is formed on the driving block, and the end of the arc-shaped rod is hinged to the arc-shaped clamping member.

[0012] Preferably, an operating turntable is provided on the lead screw and outside the U-shaped connecting plate, and a holding rod is further provided on the U-shaped connecting plate.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 6 , a safety protection device with an adaptive length for high-altitude operation in a substation, including a safety protection box 1 and a safety rope 101 located inside the safety protection box 1, and further including an adaptive storage component 2 for storing the safety rope 101 and a connection component 3 for connecting to the steel truss of the substation;

[0027] The safety protection box 1 is divided into a storage cavity and a driving cavity by a vertical partition. The adaptive storage component 2 includes two sliding blocks 205 arranged in the driving cavity, a limit plate 203 located between the two sliding blocks 205, an elastic member 206 located between the limit plate 203 and the two sliding blocks 205, and a plurality of storage rods 201 located on the sliding blocks 205 and extending through the partition into the storage cavity. Guide wheels 202 are provided on the storage rods 201, and the safety rope 101 is intertwined around the guide wheels 202. A sliding hole matching the storage rod 201 is provided on the vertical partition.

[0028] Furthermore, a guide rod 204 is also provided between the limit plate 203 and the two sliding blocks 205; a guide through hole for cooperating with the guide rod 204 is provided on the sliding block 205.

[0029] When traditional power operators work at heights in a substation, especially when working on the steel truss of a substation, due to the special structure of the steel truss (there are many vertical bars, diagonal bracing bars, cross diagonal bars, etc.), when the head of the safety belt, i.e., the safety rope 101, of the power operator is firmly fastened, the excess safety rope 101 will hang down naturally and be distributed beside the power operator. When the power operator walks and works on the steel truss, the hanging safety rope 101 will be easily affected by the steel truss, which will cause the power operator to frequently swing the safety rope 101, thus eliminating the influence of the safety rope 101 on the work of the power operator.

[0030] In the present utility model, the excess safety rope 101 is stored by the adaptive storage component 2 in the safety protection box 1, which reduces the length of the safety rope 101 hanging down naturally, and further reduces the influence of the safety rope 101 on the working area of the power operator. At the same time, if the power operator moves, the safety rope 101 can be smoothly pulled out from the safety protection box 1. After returning to the original position, the pulled-out safety rope 101 can be stored under the action of the adaptive storage component 2, so that the safety rope 101 can adapt to the length of working at heights, effectively eliminating the influence of the too-long safety rope 101 on power operation and improving the safety guarantee of working at heights.

[0031] The working principle of the adaptive storage component 2 in the present utility model is as follows: In the initial stage, the head of the safety rope 101 is fixedly arranged in the safety protection box 1, and then the safety rope 101 is wound around a plurality of guide wheels 202 in sequence. Since the specific number of the guide wheels 202 is four, that is, two on each side inside the safety protection box 1, the shape of the safety rope 101 after winding is an "S" shape.

[0032] When the power operator moves, the safety rope 101 will be pulled, which will cause the length of the safety rope 101 inside the safety protection box 1 to become shorter, and further drive all the guide wheels 202 inside the safety protection box 1 to move towards the center, thus completing the wire release of the safety rope 101 in the safety protection box 1. When the power operator moves back to the initial area, under the action of the four elastic members 206, the sliding block 205 moves towards the side away from the limiting plate 203. Since the storage rod 201 is arranged on the sliding block 205, when the sliding block 205 moves, it will drive the storage rod 201 to move towards both sides of the safety protection box 1. And since the guide wheel 202 is rotatably arranged on the storage rod 201, it will drive the safety rope 101 exposed outside the safety protection box 1 to be retracted into the safety protection box 1.

[0033] Since the entire adaptive storage component 2 provides the storage power for the safety rope 101 through four elastic members 206, the safety rope 101 can be adaptively stored when the power operator moves, and the pulled-out length of the safety rope 101 can automatically adapt to the usage requirements of the power operator, thereby reducing the interference of the safety rope 101 on power operations and effectively protecting the safety of the power operator.

[0034] Embodiment 2

[0035] Please refer to Figures 5 - 6 , this embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, please refer to each other and will not be elaborated in detail here.

[0036] As a further technical solution of this embodiment, the connection component 3 includes a U-shaped connecting plate 301, two arc-shaped clamping members 302 rotatably arranged in the U-shaped connecting plate 301, and an operating component for driving the two arc-shaped clamping members 302 to open and close;

[0037] An anti-slip rubber pad is provided on the inner side of the arc-shaped clamping member 302, a connecting ring 3021 is provided at the end of the arc-shaped clamping member 302, a connecting buckle 102 for cooperating with the connecting ring 3021 is provided on the safety protection box 1, and the connecting buckle 102 and the connecting ring 3021 are fixedly connected by a connecting bolt.

[0038] Furthermore, the operating component includes a lead screw 303 rotatably arranged in the U-shaped connecting plate 301, a driving block 304 slidably arranged in the U-shaped connecting plate 301, and two arc-shaped rods 305 rotatably arranged on both sides of the driving block 304; an internal threaded hole for cooperating with the lead screw 303 is provided on the driving block 304, and the end of the arc-shaped rod 305 is hinged to the arc-shaped clamping member 302.

[0039] Furthermore, an operating turntable 3031 is provided on the lead screw 303 and outside the U-shaped connecting plate 301, and a holding rod is also provided on the U-shaped connecting plate 301.

[0040] The traditional safety rope 101 is hung on the steel truss by winding, which causes the winding part of the safety rope 101 to often rub against the steel truss when the power operator moves. When the force is too large, it will damage the protective paint surface of the steel truss, resulting in a significant reduction in the service life of the steel truss. In order to reduce the occurrence of this situation, the present utility model also provides a connection component 3 on the safety protection box 1. By hanging the connection component 3 on the steel truss and then fixedly connecting the connection component 3 to the safety protection box 1 through a connecting bolt, the hanging of the entire safety protection box 1 is realized, effectively protecting the safety of the power operator, and at the same time, it can also protect the protective paint surface of the steel truss;

[0041] The method of hanging the connecting component 3 is specifically as follows: The power operator can determine the angle of the U-shaped connecting plate 301 through the holding rod, and then turn the operation turntable 3031, so that the driving block 304 moves towards one side of the two arc-shaped clamping members 302. Since two arc-shaped rods 305 are rotatably arranged on both sides of the driving block 304, and the other ends of the arc-shaped rods 305 are hinged to the corresponding arc-shaped clamping members 302, turning the lead screw 303 can drive the two arc-shaped clamping members 302 to close, thereby fixing the entire connecting component 3 to the main beam of the steel truss and completing the hanging of the connecting component 3. Since the inner side of the arc-shaped clamping member 302 is provided with an anti-slip rubber pad, it can protect the outer surface of the main beam of the steel truss after hanging and reduce the damage of the connecting component 3 to the steel truss;

[0042] When the two arc-shaped clamping members 302 are closed, the two staggered connecting rings 3021 coincide with each other, and then the connecting buckle 102 and the connecting ring 3021 are fixedly connected through a connecting bolt, thereby completing the fixed connection between the connecting component 3 and the safety protection box 1, and the entire safety protection device can ensure the normal work of the power operator.

[0043] Each embodiment in this specification is described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiments.
