Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to a safety protection frame structure for electric power construction. Background Art

[0002] During the inspection and installation of power facilities and road lighting, construction workers are required to climb utility poles. Common cement utility poles do not have any facilities for climbing and protection, especially in mountainous areas where large equipment cannot be used. Construction workers can only use foot buckles and safety belts for climbing protection.

[0003] In order to improve the safety of power construction operations, Chinese patent application No. 2023110824878 discloses a ground protection device for power tower construction, the technical solution includes two protective nets cooperating with the power tower, one end of the protective net is provided with a make way groove cooperating with the power tower, one end of the protective net cooperating with the power tower is provided with a support rod, the lower end of the support rod is provided with a second support leg, the other end of the protective net away from the power tower is connected with a net wrapping mechanism, the lower end of the net wrapping mechanism is provided with a first support leg, the upper end of the support rod is provided with a first protective pad, and the upper end of the net wrapping mechanism is provided with a second air cushion; a protective net is arranged below the power tower to form a safe falling area below the power tower, which can cushion falling personnel and reduce casualties; at the same time, it can block objects falling from above to prevent injuries to personnel below, thereby improving safety protection.

[0004] The solution recorded in the above patent is used to set up a buffer area on the way of falling to prevent the occurrence of hard collision after the danger of falling occurs, but it cannot prevent the danger from occurring at the first time, and it is necessary to provide a protective net with a large enough range to ensure that objects falling from a height are caught. Although the first support leg and the second support leg in the patent solution are retractable, the protective net can be extended to the area as close to the construction work as possible, and although it can intervene at the first time of the danger to prevent greater harm due to the increase in kinetic energy, it requires support legs that are almost as long as the telephone poles to achieve this, which greatly increases the difficulty of installing the protective device.

[0005] In summary, there is an urgent need for a safety protection frame structure for electric power construction that can provide protection for construction workers in the first place, is simple to install, and has a reliable structure. Summary of the invention

[0006] In view of the problems of complicated installation and failure to provide protection in the first time in the prior art, a safety protection frame structure for electric power construction is proposed which can provide protection for construction workers in the first time and has simple installation and reliable structure.

[0007] In order to solve the above problems, the technical solution of the present invention is:

[0008] A safety protection frame structure for power construction, comprising a protection platform and a clamping seat; the clamping seat comprises a fixed clamping member, a connecting member, and a movable supporting member; the connecting member is detachably connected to the fixed clamping member, and the movable supporting member comprises a movable clamping part and a supporting part, wherein when the supporting part moves upward relative to the connecting member, the movable clamping part and the fixed clamping member move away from each other, and when the supporting part moves downward relative to the connecting member, the movable clamping part and the fixed clamping member move toward each other; the protection platform is arranged on the supporting part.

[0009] As a preferred technical solution, both the fixed clamp and the protective platform are provided with locking rings, and the locking rings are used to connect a safety rope.

[0010] As a preferred technical solution, the length of the safety rope connected to the locking ring on the protective platform is shorter than the length of the safety rope connected to the locking ring on the fixed clamp.

[0011] As a preferred technical solution, it also includes a movable connecting rod and a limiting member; one end of the movable connecting rod is rotatably connected to the movable clamping part, and the other end is rotatably connected to the supporting part; the limiting member includes a guide rod and a guide hole; the guide rod is arranged on the movable clamping part, and the guide hole is arranged on the connecting member; the guide rod can slide along the guide hole.

[0012] As a preferred technical solution, anti-slip pads are provided on the clamping surfaces of the fixed clamping piece and the movable clamping part.

[0013] As a preferred technical solution, the anti-slip pad is composed of a plurality of independent gaskets, and there is a gap between the independent gaskets adjacent to each other in the axial direction.

[0014] As a preferred technical solution, the independent gasket includes an upward turning portion and a liquid scraping portion, and the liquid scraping portion is adjacent to the gap.

[0015] As a preferred technical solution, the surface of the upward-turning portion protrudes from the liquid-wiping portion.

[0016] Beneficial effects of the present invention:

[0017] 1. The safety protection frame structure of the power construction of the present invention can directly fix the protection platform arbitrarily below the working position of the construction personnel on the electric pole through the clamping seat. When the danger occurs, it can take over the construction personnel in the first time and provide safety protection for the construction personnel. The clamping of the fixed clamping member and the movable clamping member on the clamping seat is controlled by the construction personnel, and it moves with the construction personnel throughout the rising and falling process, which greatly reduces the impact on the climbing efficiency. The protection platform is connected to the support part of the movable support member, and the support part controls the relative movement of the movable clamping part. When the force on the protection platform on the support part is greater, the pressure applied by the movable clamping part and the fixed clamping member on the electric pole is greater, and the friction between the clamping seat and the electric pole is greater, and the protection is more effective. The protection platform of the present invention can not only play a protective role, but also when long-term construction work is required, the construction personnel can directly stand in the protection platform to work. The protection platform and the clamping seat of the present invention do not have a complicated driving structure, simple maintenance, high reliability, and a single person can complete the work.

[0018] 2. The anti-skid pads on the fixed clamping parts and the movable clamping parts of the safety protection frame structure for power construction described in the present invention are composed of a number of independent gaskets with gaps above and below, and the independent gaskets are arranged in sequence and spaced apart in the axial direction. When the anti-skid pad slides relatively on the pole tower, the edge of the independent gasket will scratch the surface of the pole tower, and the liquid on its surface will be gathered in the gap instead of being always isolated between the anti-skid pad and the surface of the pole tower, thereby eliminating the factors of slipping and reducing the risk of slipping.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to better understand the safety protection frame structure of power construction provided by the present embodiment, the existing power construction structure is briefly introduced below. The existing power construction protection structure refers to that the feet of the construction workers are clamped on the electric poles through foot buckles, and a safety rope connected to the electric poles is tied around the waist and abdomen to fix the upper body, and the up and down movement is achieved by alternating movement of the foot buckles. During construction, the feet of the construction workers are in an up and down state, and the feet play a fixed role and cannot move at will. If long-term construction is required, it is very easy to cause physical discomfort; the safety rope at the waist can only prevent the body from tilting sideways, and cannot prevent falling when the foot fixation fails.

[0035] In the prior art, there is a high-altitude lamp post climbing frame with application number 2020208878316, which includes a manned device and a climbing device. The manned device includes a manned board and a protective frame, and the climbing device includes a telescopic structure and a pole holding structure arranged in pairs. The pole holding structure is installed on the electric pole. The operator enters the manned board in the protective frame and locks the operating door. The hydraulic cylinder 2 on the bottom pole holding structure extends, so that the bottom pole holding structure first holds the electric pole tightly. The hydraulic cylinder 1 extends, driving the manned device and the top pole holding structure to move upward on the electric pole. Then, the hydraulic cylinder 2 on the top pole holding structure extends, so that the top pole holding structure holds the electric pole tightly. At this time, the hydraulic cylinder 2 on the bottom pole holding structure shortens, and the bottom pole holding structure loosens the electric pole. The hydraulic cylinder 1 shortens, so that the bottom pole holding structure and the bottom plate move upward. This process is repeated to allow the manned device to climb on the electric pole. However, this mechanism of alternating climbing through hydraulic cylinders has a climbing stroke that each time depends on the stroke of hydraulic cylinder one, and cannot move upward continuously, which greatly reduces the climbing efficiency. Its safety depends not only on the strength of the material itself, but also on the friction between hydraulic cylinder two and the pole. When hydraulic cylinder two fails, there is a risk of falling. Therefore, although the above-mentioned climbing frame frees the feet of the construction workers, it sacrifices the efficiency and flexibility of climbing. The climbing frame itself cannot be self-locking and lacks anti-slip insurance, which reduces safety. In addition, the structure is complicated and is not suitable for single-person transfer operations.

[0036] In order to overcome the above-mentioned defects in the prior art, please refer to the attached Figure 1 The present invention provides a safety protection frame structure for power construction, including a protection platform 1 and a clamping seat 2; the protection platform 1 is used to provide safety protection for construction personnel. In this embodiment, the protection platform 1 is a semi-enclosed structure with a fence, and a locking ring 3 for connecting with a safety rope is also provided on the protection platform 1; the clamping seat 2 is used to fix with the electric pole, and at the same time, the protection platform 1 can make the clamping seat 2 clamp the electric pole more stably when it is under force. For details, please refer to the attached Figure 2 The clamping seat 2 includes a fixed clamping member 21, a connecting member 22, and a movable supporting member 23. The movable clamping portion 231 on the movable supporting member 23 can move away from or closer to the fixed clamping member 21 under the movement of the supporting portion 232, so as to achieve the clamping and loosening of the electric pole. The fixed clamping member 21 is provided with a semi-arc groove adapted to the pole body of the electric pole, and a locking ring 3 for connecting a safety rope is also provided above the fixed clamping member 21.

[0037] Please see attached Figure 3In this embodiment, the connecting member 22 is a symmetrical plate-like structure, one end of which is used for detachable fixed connection with the fixed clamping member 21 by bolts, and the other end is provided with a slide groove. The movable support member 23 includes a movable clamping portion 231 and a support portion 232. The support portion 232 is a plate-like or steel frame structure. Blocks corresponding to the slide grooves of the connecting member 22 are provided on both sides of the support portion 232. The direction of the slide groove is the direction of movement of the protective platform 1, that is, the direction of movement along the electric pole. The movable clamping portion 231 is also a semi-arc groove adapted to the pole body such as the electric pole, and the movable clamping portion 231 is connected to the support portion 232 by two movable connecting rods 233. One end of the movable link 233 is connected to the movable clamping part 231 through a rotating shaft, and the other end is connected to the support part 232 through a rotating shaft to form a parallelogram structure. In order to enable the movable clamping part 231 to move away from or close to the electric pole under the pulling of the movable link 233, the length of the movable link 233 is greater than the distance between the support part 232 and the electric pole, so that effective pressure can always be provided for the movable clamping part 231. The present invention is also provided with a limit member 24, which includes a guide rod 241 arranged at the bottom of the movable clamping part 231 and a guide hole arranged at the bottom of the connecting member 22, and the guide rod 241 is adapted to pass through the guide hole.

[0038] How to use the present invention: Please see the attached Figure 4 , attached Figure 4One of the construction methods is shown. The safety rope is not shown in the figure. The construction workers place the fixed clamping member 21 of the safety protection frame structure of the power construction described in the present invention on one side of the bottom of the electric pole, and the movable support member 23 is placed on the other side of the electric pole. The connecting member 22 connected to the movable support member 23 is fastened to the fixed clamping member 21 by bolts; before climbing, the support part 232 is pressed down so that the movable clamping part 231 and the fixed clamping member 21 clamp the electric pole between them. The construction workers can stand on the protective platform 1 to test its stability. The construction workers also use foot buckles and waist safety ropes to climb, and the human body is located directly above the protective platform 1. A shorter safety rope is connected between the locking ring 3 of the protective platform 1 and the waist of the construction workers; a longer safety rope is taken, one end of which is connected to the locking ring 3 on the fixed clamping member 21, and the other end is vertically connected upward to the safety belt used to fix the waist and abdomen of the construction workers. The safety rope can be used to control the movement of the fixed clamping member 21 and the movable support member 23 respectively. The safety rope connected to the fixed clamping member 21 is relatively long, which can simplify the control operation of the movable support member 23, and facilitate the overall movement by controlling the movement of the support part 232. Specifically, when the construction workers climb upward, the safety rope connected to the protective platform 1 follows the construction workers' waist to move up. When the clamping seat 2 and the electric pole are in a state of tightening and clamping, the protective platform 1 will first bring The movable support part 232 moves up relative to the connecting member 22, so that the movable clamping part 231 gradually moves away from the fixed clamping part 21 along the direction of the guide hole. When the clamping force between the clamping seat 2 and the electric pole disappears, the safety protection frame structure of the electric power construction described in the present invention can move up with the construction personnel. When it moves up to the working position, it is only necessary to move the support part 232 down relative to the connecting member 22, so that the fixed clamping part 21 and the movable clamping part 231 clamp the electric pole to fix the position of the protection platform 1; it should be understood that the length of the movable connecting rod 233 is greater than the distance between the support part 232 and the electric pole, so that the greater the force applied to the protection platform 1, the tighter the clamping; similarly, the clamping force between the clamping seat 2 and the electric pole disappears first, and when the construction personnel descend, the safety protection frame structure of the electric power construction described in the present invention can descend under its own weight as the safety rope is relaxed.

[0039] It should be noted that the safety protection frame structure of the power construction of the present invention can directly fix the protection platform 1 arbitrarily below the working position of the construction personnel on the electric pole through the clamping seat 2. When the danger occurs, it can take over the construction personnel in the first time and provide safety protection for the construction personnel, and is particularly suitable for climbing equipment such as equal-diameter poles and towers. The clamping of the fixed clamping member 21 and the movable clamping member on the clamping seat 2 is controlled by the construction personnel, and it moves with the construction personnel throughout the rising and falling process, greatly reducing the impact on the climbing efficiency. The protection platform 1 is connected to the support portion 232 of the movable support member 23, and the support portion 232 controls the relative movement of the movable clamping portion 231. When the protection platform 1 on the support portion 232 is subjected to greater force, the greater the pressure exerted on the electric pole by the movable clamping portion 231 and the fixed clamping member 21, the greater the friction between the clamping seat 2 and the electric pole, and the more effective the protection. The protection platform 1 of the present invention can not only play a protective role, but also when long-term construction work is required, the construction personnel can directly stand in the protection platform 1 to work. The protection platform 1 and the clamping seat 2 of the present invention do not have a complicated driving structure, are easy to maintain, have high reliability, and can be completed by a single person.

[0040] Example 2

[0041] In order to protect the semicircular arc surface on the fixed clamping member 21 and the movable clamping portion 231 and prevent the long-term friction from reducing the strength of the structure, in some preferred embodiments, see the attached Figure 5 The surfaces used for clamping on the fixed clamping member 21 and the movable clamping portion 231, that is, the semi-arc groove surfaces of the fixed clamping member 21 and the movable clamping portion 231, are both provided with anti-slip pads 4, which can not only increase the friction coefficient between the clamping seat and the pole, but also provide buffering to avoid wear on the surface of the semi-arc groove.

[0042] In addition to routine inspection and maintenance, power transmission failures are likely to occur in thunderstorm weather. At this time, emergency repairs need to be carried out as soon as possible after the thunderstorm disappears. However, at this time, facilities such as poles are still wet. Even if an anti-skid pad 4 is provided on the contact surface, the liquid in the area covered by the anti-skid pad 4 cannot be discharged, so there is still a risk of slipping. In order to solve the above problem, please refer to the attached Figure 6 The anti-skid pad 4 is composed of a plurality of independent gaskets 41 with gaps 42 above and below. Specifically, in the present embodiment, the independent gaskets 41 are arranged in sequence along the semi-arc surfaces of the fixed clamping member 21 and the movable clamping portion 231 in the axial direction. When the anti-skid pad 4 slides relatively on the pole tower, the edge of the independent gasket 41 will scratch the surface of the pole tower, and the liquid on the surface will be gathered in the gaps 42 instead of being always isolated between the anti-skid pad 4 and the surface of the pole tower, thereby eliminating the factors causing slippage and reducing the risk of slippage.

[0043] Preferably, in some embodiments, in order to further eliminate the effect of slippery, see the attached Figure 7 , Attachment Figure 8 The independent gasket 41 is provided with an upper flip surface 411 on its surface, and the upper flip surface 411 can move relative to the surface of the independent gasket 41. A liquid scraping portion 412 is provided below the upper flip surface 411, and the liquid scraping portion 412 is connected to the gap 42. When in use, when the surface of the independent gasket 41 matches the surface of the tower, if slippage occurs, please refer to the attached Fig. 9 , attached Fig. 9 The schematic diagram of the upper flip surface 411 fully flipped up is shown, and it can also be in a wrinkled upward gathering state; the upper flip surface 411 moves upward to expose the surface of the gasket in the next layer which is still in a dry state. At the same time, during the sliding process, the scraper 412 scrapes the liquid remaining on the pole tower into the gap 42, and the liquid on the outer surface of the pole tower is absorbed by the surface of the upper flip surface 411 that first contacts the pole tower, and after the upper flip surface 411 deforms and shrinks, the liquid at the corresponding pole tower position is in a wiped state, and finally, under the action of pressure, the surface of the dry independent gasket 41 in the inner layer of the corresponding upper flip surface 411 fits with the pole tower after wiping and drying, ensuring its friction, thereby improving safety, and the upper flip surface 411 is in a wrinkled or flipped state, which can further prevent the liquid from flowing downward. It should be noted that in some preferred embodiments, the surface of the upper flip portion can be slightly higher than the scraper 412, and a protruding convex structure will be set on the outer surface of the upper flip surface 411 to facilitate the upward movement of the upper flip portion.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the principle of the present invention. These improvements and supplements should also be regarded as the scope of protection of the present invention.
