Description

Technical Field

[0001] This utility model relates to the field of bridge support technology, and more specifically, to a bridge support dismantling device. Background Technology

[0002] For small bridge piers, in some pedestrian bridges or small highway bridges, the diameter of the support steel pipe is relatively small, commonly around 48mm. The wall thickness of this steel pipe is generally around 3-3.5mm. It can meet the requirements of relatively light superstructure load and small construction load. For example, in the construction of some simple rural bridges, the bridge support can achieve the purpose of supporting the formwork and a small amount of concrete pouring weight by using steel pipes with a diameter of 48mm.

[0003] Currently, the method for dismantling bridge supports involves separating the assembled steel pipes. This process is typically carried out by workers who unscrew the bolts connecting the pipes and then dismantle them one by one. In practice, to improve efficiency, workers sometimes simply throw the dismantled pipes onto the ground. This can easily cause the pipes to bend or break, rendering them unusable later. Therefore, a bridge support dismantling device is proposed to address these issues. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] Reference Figures 1-4This utility model provides a technical solution: a bridge support dismantling device, including a base plate 1 and a dismantling mechanism 3, with a vertical pole 2 installed on the side of the upper surface of the base plate 1. The dismantling mechanism 3 includes a movable rod 31, which is slidably installed on the upper surface of the base plate 1. A first connecting rod 311 is rotatably installed on the inner side of the movable rod 31, and a second connecting rod 32 is rotatably installed on the inner side of the vertical pole 2. A round rod 321 is stably installed on the inner side of the first connecting rod 311 and the second connecting rod 32. A partition plate 33 is installed above the base plate 1 and stably connected to the outer surface of the vertical pole 2. A push rod 331 is rotatably installed on the upper surface of the partition plate 33, and one end of the push rod 331 is rotatably connected to the first connecting rod 311.

[0032] In a preferred embodiment, a sliding groove 4 is provided on the upper surface of the base plate 1, and a slider 5 is provided inside the sliding groove 4. A movable rod 31 is fixedly installed on the upper surface of the slider 5. When the height position of the steel pipe is adjusted, the movable rod 31 needs to be moved to increase the distance between the movable rod 31 and the upright 2, so that the first connecting rod 311 and the second connecting rod 32 can rotate normally, thereby changing the position of the steel pipe so as to pick up the steel pipe.

[0033] In a preferred embodiment, one end of the first connecting rod 311 is rotatably connected to the inner side of the upright 2, and one end of the second connecting rod 32 is rotatably connected to the inner side of the movable rod 31. To ensure stable use of the first connecting rod 311 and the second connecting rod 32, both ends of the first connecting rod 311 and the second connecting rod 32 are rotatably connected to the inner sides of the upright 2 and the movable rod 31, respectively. This device provides two first connecting rods 311 and two connecting rods 32, which are installed between the upright 2 and the movable rod 31 to ensure stable use of the first connecting rod 311 and the second connecting rod 32.

[0034] In a preferred embodiment, a support column 7 is stably installed at the bottom of the partition 33, and the bottom of the support column 7 is stably connected to the upper surface of the base plate 1. An electric telescopic rod 8 is rotatably connected to the upper surface of the partition 33, and the telescopic end of the electric telescopic rod 8 is rotatably connected to the push rod 331. In this device, the partition 33 is set above the base plate 1, and the support column 7 is fixedly installed on the upper surface of the base plate 1. The support column 7 supports the partition 33, so that the partition 33 can be used stably, and the electric telescopic rod 8 and the push rod 331 can be used stably.

[0035] Since this device is used outdoors, where outdoor power is not very convenient, and the device needs to control the normal operation of the electric telescopic pole 8, a storage battery 9 is stably installed on the upper surface of the base plate 1. The storage battery 9 is electrically connected to the electric telescopic pole 8, and supplies power to the electric telescopic pole 8 so that the electric telescopic pole 8 can be used normally and control the rotation of the push rod 331 to change the height position of the steel pipe.

[0036] When placing and collecting steel pipes, this device ensures that the steel pipes are stably placed on the first connecting rod 311 and the second connecting rod 32. A connecting plate 10 is stably installed on the outer side of the slider 5. The connecting plate 10 is internally threaded with a screw 11. A threaded hole 12 is provided on the upper surface of the base plate 1, and the screw 11 is screwed into the threaded hole 12 to limit the movement of the movable rod 31. By screwing the screw 11 into the threaded hole 12, the slider 5 is positioned, thereby positioning the movable rod 31. This prevents the first connecting rod 311 and the second connecting rod 32 from rotating, thus stably placing the steel pipes on the first connecting rod 311 and the second connecting rod 32 for easy use.

[0037] When dismantling the steel pipe, the bolts at one end of the steel pipe are unscrewed. When one end of the steel pipe is loose, the steel pipe is prone to tipping over under its own weight, causing danger. To solve this problem, a clamping mechanism 13 is installed on the top of the upright 2. The clamping mechanism 13 includes a support rod 131, a rectangular plate 132 and a conical hole 133. The support rod 131 is fixedly installed on the top of the upright 2, and the rectangular plate 132 is stably connected to the top of the support rod 131. A conical hole 133 is opened on one side of the rectangular plate 132, and the conical hole 133 penetrates the upper and lower surfaces of the rectangular plate 132. A sliding hole 14 is opened on the outer side of the upright 2, and a moving block 6 is set inside the sliding hole 14. One end of the first connecting rod 311 and the second connecting rod 32 are respectively rotatably connected to the moving block 6.

[0038] In practical use, when disassembling one end of the steel pipe, to prevent the steel pipe from tipping over, this device is pushed to the position of the steel pipe, moving the steel pipe into the interior of the rectangular plate 132, that is, moving the steel pipe into the interior of the conical hole 133, and locking the steel pipe inside the conical hole 133. After the steel pipe is continuously disassembled, it can still be kept in a vertical state. This method can limit the position of the steel pipe and prevent it from tipping over during disassembly, thus avoiding danger.

[0039] Specifically, the working process or principle of a bridge support dismantling device is as follows: Currently, the method of dismantling bridge supports involves disassembling the assembled steel pipes. The dismantling process is generally carried out by workers who unscrew the bolts at the joints of the steel pipes and then dismantle the steel pipes one by one. In actual operation, in order to improve work efficiency, workers may simply throw the dismantled steel pipes directly on the ground. Such operation can easily cause the steel pipes to bend due to impact, rendering them unusable later. Therefore, this device was designed to solve this problem.

[0040] This device can place disassembled steel pipes on the first connecting rod 311 and the second connecting rod 32 to collect the steel pipes, avoiding direct disposal on the ground and preventing deformation. This ensures the steel pipes can be reused. Specifically, the device can be moved to the site by pushing it directly. The device can be pushed to the site by the rolling wheels on the base plate 1. Since the steel pipes are multiple pieces assembled together, when disassembling one end of the steel pipe, to prevent the steel pipe from tipping over, the device will be pushed to the position of the steel pipe, moving the steel pipe into the interior of the rectangular plate 132, that is, into the interior of the conical hole 133. The steel pipe is then secured inside the conical hole 133. After continuous disassembly of the steel pipe, it can still maintain a vertical position. Then, the steel pipe is taken out from inside the conical hole 133 and placed horizontally on the first connecting rod 311 and the second connecting rod 32.

[0041] When this device is in use, the first connecting rod 311 and the second connecting rod 32 are set to an inclined state. When the steel pipe is placed on the first connecting rod 311 and the second connecting rod 32, the steel pipe will automatically slide to the bottom position to place the steel pipe and avoid throwing it directly on the ground, which would cause the steel pipe to bend and affect its use. In this way, the steel pipe can be disassembled continuously.

[0042] When the number of steel pipes placed on this device reaches a certain amount, it is no longer possible to place more. At this point, the steel pipes need to be transferred to a transport vehicle for continued use. Therefore, this device can be moved to the side of the transport vehicle. To facilitate the retrieval of the steel pipes, this device can control the electric telescopic rod 8. The retraction of the telescopic end of the electric telescopic rod 8 will drive the push rod 331 to rotate, lowering the height of the push rod 331. At this time, the first connecting rod 311 and the second connecting rod 32 will slowly descend, bringing the originally tilted first connecting rod 311 and the second connecting rod 32 to a horizontal state, lowering the height of the steel pipes, making it easier to retrieve and load the steel pipes onto the vehicle for convenient use.

[0043] Since the movable rod 31 is slidably mounted on the base plate 1, when collecting steel pipes, the screw 11 is used to position the slider 5, thereby positioning the movable rod 31. When it is necessary to change the position height of the steel pipe, the screw 11 can be unscrewed from the slider 5, so that the movable rod 31 can move normally. When the first connecting rod 311 and the second connecting rod 32 rotate, they will squeeze the movable rod 31 to lower the position height of the steel pipe, so as to facilitate the picking up of the steel pipe for loading and use.

[0044] It should be noted that the battery 9 and the electric telescopic pole 8 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
