Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a lightweight anti-overturning scaffolding for high-altitude operation in the subway. Background Technique

[0002] The scaffolding for the subway refers to a temporary structure used in subway construction, mainly for support, maintenance, and safety passages, etc. This kind of scaffolding is usually composed of steel pipes and fasteners, and there is also a trend to use disk-lock scaffolding. The characteristics of the subway scaffolding are high load-bearing requirements, strict space limitations, and complex construction environments, etc.

[0003] Due to the special subway environment, when maintaining the pipelines at the top of the tunnel, the bottom of the scaffolding is usually installed with load-bearing wheels so that the scaffolding can be towed by a locomotive on the track. However, the conventional scaffolding for the track is usually heavy. The main reason is that the standard gauge of the track is 1.435 meters, which is a universal standard in the world. Therefore, when installing pipelines on the scaffolding, in order to avoid the risk of the scaffolding tipping over due to top-heavy and bottom-light, the weight below will be increased. However, increasing the weight will lead to a reduction in the number of load carriages of the towing locomotive for maintenance, thereby reducing the carrying capacity of the scaffolding for a single maintenance trip. To solve this technical problem, the utility model proposes a lightweight anti-overturning scaffolding for high-altitude operation in the subway. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a lightweight anti-overturning scaffolding for high-altitude operation in the subway, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A lightweight anti-overturning scaffolding for high-altitude operation in the subway, including a load-bearing plate. Above the load-bearing plate, there is a carrying basket. Below the carrying basket, there is a hydraulic press I. On the outer surface of the load-bearing plate, there is a hydraulic press II. Below the load-bearing plate, there is a positioning frame. Below the load-bearing plate, there are two clamping clips.

[0007] Preferably, a steel wheel is rotatably connected to the outer surface of the load-bearing plate. Below the load-bearing plate, there are pre-set cement sleepers and steel rails. The outer surface of the steel wheel is in close contact with the outer surface of the steel rail. A buffer is fixedly installed on the outer surface of the load-bearing plate, and an iron fence is fixedly installed on the outer surface of the buffer.

[0008] Preferably, the outer surfaces of the two clamping clips are rotatably connected to each other. The outer surface of the clamping clip is rotatably connected to the outer surface of the load-bearing plate. The outer surface of the clamping clip is in close contact with the outer surface of the steel rail. A hydraulic rod is rotatably connected to the bottom surface of the load-bearing plate, and the output end of the hydraulic rod is rotatably connected to the outer surface of the clamping clip.

[0009] Preferably, a transmission rod is slidably connected to the inner wall of the load-bearing plate. The bottom end of the transmission rod is fixedly installed on the outer surface of the positioning frame. A push plate is fixedly installed at the top end of the transmission rod. The output end of the second hydraulic press is fixedly installed on the outer surface of the push plate.

[0010] Preferably, a first support frame is rotatably connected to the outer surface of the load-bearing plate. A second support frame is rotatably connected to the outer surface of the first support frame. A load-bearing wheel is rotatably connected to the outer surface of the second support frame.

[0012] Preferably, a guardrail is fixedly installed on the outer surface of the carrying basket. A climbing frame is installed on the outer surface of the guardrail.

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

[0014] In the utility model, through the cooperation between the steel rail, the concrete sleeper, the carrying basket, the first hydraulic press, the second hydraulic press, the positioning frame, the load-bearing plate and the clamp, the load-bearing plate is made of conventional metal materials and has honeycomb-shaped openings inside, which can play a certain supporting role. When it is necessary to deploy the scaffolding, the second hydraulic press can be started. The second hydraulic press can push the positioning frame so that the positioning frame can be closely attached to the concrete sleeper for laying the steel rail, so as to prevent the scaffolding from slipping when there is no traction force. At the same time, the clamp can clamp the steel rail to prevent the risk of the scaffolding tipping over due to its light weight. The operator can ride in the carrying basket and start the first hydraulic press to lift the height for normal operation. Thus, while reducing the weight, it can also ensure that the scaffolding will not shift or tip over during the deployment process, solving the problem that increasing the weight will lead to a decrease in the number of load carriages of the traction locomotive for maintenance, thereby reducing the carrying capacity of the scaffolding per maintenance trip.

[0015] In the utility model, through the cooperation between the guardrail, the carrying basket and the climbing frame, the guardrail can provide the most basic protection for the operators on the carrying basket. There are two bent rods installed on the climbing frame, which can make it convenient for the operators to hold when they are about to board or get off the carrying basket, so as to reduce the risk of the operators slipping and falling due to the slippery soles.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figures 1-5As shown in the figure, a portable scaffolding for high-altitude operation in the subway to prevent tipping includes a load-bearing plate 1. Above the load-bearing plate 1 is a carrying basket 2. Below the carrying basket 2 is a hydraulic press 1. On the outer surface of the load-bearing plate 1 is installed a hydraulic press 2. Below the load-bearing plate 1 is a positioning frame 5. Below the load-bearing plate 1 are two clamps 6. The load-bearing plate 1 is made of conventional metal materials and has honeycomb-shaped openings inside, which can play a certain supporting role. When the scaffolding needs to be deployed, the hydraulic press 2 can be started. The hydraulic press 2 can push the positioning frame 5 so that the positioning frame 5 can closely adhere to the concrete sleeper 8 for laying the rail 9, to prevent the scaffolding from slipping when there is no traction force. At the same time, the clamp 6 can clamp the rail 9 to prevent the risk of the scaffolding tipping over due to its light weight. The operator can ride in the carrying basket 2 and start the hydraulic press 1 to lift the height for normal operation. Thus, while reducing the weight, it can also ensure that the scaffolding will not shift or tip over during the deployment state, solving the problem that increasing the weight will lead to a reduction in the number of loaded carriages of the traction locomotive for maintenance, thereby reducing the carrying capacity of the scaffolding per maintenance trip.

[0024] A steel wheel 7 is rotatably connected to the outer surface of the load-bearing plate 1. Below the load-bearing plate 1, there are preset concrete sleeper 8 and rail 9. The outer surface of the steel wheel 7 is in close contact with the outer surface of the rail 9. A buffer 10 is fixedly installed on the outer surface of the load-bearing plate 1. An iron fence 11 is fixedly installed on the outer surface of the buffer 10. The load-bearing plate 1 can move on the rail 9 through the steel wheel 7. The buffer 10 can facilitate the slip car dispatching of the traction locomotive in the subway depot. The iron fence 11 can reduce the risk of construction-generated sundries directly falling on the rail 9.

[0025] The outer surfaces of the two clamps 6 are rotatably connected to each other. The outer surface of the clamp 6 is rotatably connected to the outer surface of the load-bearing plate 1. The outer surface of the clamp 6 is in close contact with the outer surface of the rail 9. A hydraulic rod 12 is rotatably connected to the bottom surface of the load-bearing plate 1. The output end of the hydraulic rod 12 is rotatably connected to the outer surface of the clamp 6. When the hydraulic rod 12 operates, it can push the two clamps 6 to closely adhere to the two rails 9. And the rail 9 for the track is I-shaped, so that when the two clamps 6 closely adhere to the rail 9, they can be mutually clamped with the two rails 9, and thus it is not easy to tip over.

[0026] A transmission rod 13 is slidably connected to the inner wall of the load-bearing plate 1. The bottom end of the transmission rod 13 is fixedly installed on the outer surface of the positioning frame 5. The top end of the transmission rod 13 is fixedly installed with a push plate 14. The output end of the hydraulic press 2 is fixedly installed on the outer surface of the push plate 14. When the hydraulic press 2 operates, it can push the push plate 14. The push plate 14 can simultaneously push the four transmission rods 13 to move downward. When the transmission rods 13 move downward, the positioning frame 5 can be simultaneously sleeved on the four concrete sleepers 8 for the subway, thus avoiding the situation of the equipment body slipping.

[0027] The outer surface of the load-bearing plate 1 is rotatably connected to a support frame 15, the outer surface of the support frame 15 is rotatably connected to a support frame 2 16, the outer surface of the support frame 2 16 is rotatably connected to a load-bearing wheel 17, the outer surface of the upper support frame 15 is rotatably connected to the outer surface of the carrying basket 2, the outer surface of the lower load-bearing wheel 17 is slidably connected to the outer surface of the load-bearing plate 1, the upper load-bearing wheel 17 is slidably connected to the bottom surface of the carrying basket 2, the support frame 15 and the support frame 2 16 can push the carrying basket 2 up and down under the push of external force, and with a simple structure, the occupied space is reduced as much as possible, and the light transmittance is increased, which is more suitable for dimly lit subway tunnels.

[0028] The rotation connection point between support frame 15 and support frame 2 16 is rotationally connected with a push rod 18, the outer surface of the push rod 18 is rotationally connected to the outer surface of the hydraulic press 1 3, and the output end of the hydraulic press 3 is rotationally connected to the outer surface of another push rod 18. The hydraulic press 1 3 can push the two push rods 18, so that the push rods 18 can force the support frame 1 15 and support frame 2 16 to change their own shapes, thereby driving the supporting basket 2 to move up and down.

[0029] A guardrail 19 is fixedly installed on the outer surface of the carrying basket 2, and a climbing frame 20 is installed on the outer surface of the guardrail 19. The guardrail 19 can provide the most basic protection for the workers on the carrying basket 2. Two curved rods are installed on the climbing frame 20, which can facilitate the workers to grab with their hands when they are about to board the carrying basket 2 or climb down from the carrying basket 2, so as to reduce the risk of the workers slipping and falling.
