Description

A municipal isolation bracket Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a municipal isolation support. Background Technology

[0002] Municipal isolation supports are a type of isolation railing. During municipal construction, isolation supports can be used to isolate the construction site, providing a convenient working space for construction workers. This helps improve construction efficiency, reduce unnecessary construction time and costs, prevent damage and pollution to the surrounding environment during construction, and ensure the safety of construction workers.

[0003] Currently, isolation supports are commonly used in municipal construction operations. Therefore, it is necessary to transport the isolation supports to the location of use. In this process, transportation vehicles are usually used to transport them to the designated location. However, in some places, due to road conditions, it is not convenient for transport vehicles to directly reach the installation location of the supports. In this case, workers need to unload the supports and carry them to the location of use, which greatly increases the workload of workers. Therefore, a municipal isolation support is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a municipal isolation bracket to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a municipal isolation support, including a top plate. Two columns are fixedly connected to the bottom surface of the top plate, and a base plate is fixedly connected to the bottom surface of the two columns. A plurality of railings are fixedly installed between the two columns by bolts. A sliding groove is formed on the bottom surface of each column, and a support column is slidably connected to the inner wall of the groove. A base is fixedly connected to the bottom surface of each support column. A locking bolt is threaded onto the side of each column, and the bottom surface of the locking bolt is in contact with the support column. The base plate... A U-shaped frame is fixedly installed on the top surface by bolts. A threaded post is threadedly connected to the top of the U-shaped frame. A lifting plate is rotatably connected to the bottom end of the threaded post via a bearing. The lifting plate is slidably connected to the U-shaped frame. A pin is fixedly connected to the bottom surface of the lifting plate. A through hole is opened through the top surface of the base plate. A rotating rod is rotatably connected to the inner wall of the through hole. A locking disc is fixedly connected to the top surface of the rotating rod. The pin engages with the locking disc. A connecting plate is fixedly connected to the bottom surface of the rotating rod. Two universal wheels are fixedly connected to the bottom surface of the connecting plate.

[0007] Preferably, in any of the above embodiments, the length of the support column is equal to the depth of the groove, and the top surface of the base is provided with a plurality of locking holes.

[0008] A limiting shaft is fixedly connected to the side of the support column, and a slot is opened through the side of the column. The limiting shaft is slidably connected to the column through the slot.

[0009] The thickness of the base plate is equal to the length of the rotating rod, and the locking disc and connecting plate are slidably connected to the base plate.

[0010] The top surface of the locking disc has several snap-fit ​​holes, and the pin is slidably connected to the locking disc through the snap-fit ​​holes.

[0011] A guide rod is fixedly connected to the top surface of the lifting plate. The guide rod is slidably connected to the U-shaped frame. The length of the guide rod is equal to that of the threaded column.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] When isolation brackets are needed to isolate municipal construction sites, the columns can be pushed to move under the rolling of the casters. Each connecting plate has two casters on its bottom, and the rolling of the four casters ensures stable movement of the isolation brackets, making them easier to transport and greatly reducing the workload of workers. After the isolation brackets are in the working position, the locking bolts can be turned to move them away from the support columns, thus releasing the lock on the support columns. Then, the support columns can be pulled down to make the base contact the ground. By controlling the length of the support columns extending from the sliding grooves, the casters can be lifted off the ground, making the isolation bracket installation more stable. After using the ground locking nails to install the base on the ground through the locking holes, the threaded column can be turned to move the lifting plate upwards until the pin is fully moved out of the locking hole, thus releasing the lock on the locking plate. At this time, the connecting plate can be pushed to rotate around the rotating rod until both casters are directly under the base plate. Then, the threaded column can be reversed, and the threaded drive will drive the pin to re-insert into the locking hole, thus storing the two casters and preventing them from being exposed and affecting pedestrian traffic.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0021] As shown in Figures 1 to 5, a municipal isolation support includes a top plate 1. Two columns 2 are fixedly connected to the bottom surface of the top plate 1. A base plate 3 is fixedly connected to the bottom surface of the two columns 2. Several railings 4 are bolted between the two columns 2. A sliding groove 5 is formed on the bottom surface of the columns 2. A support column 6 is slidably connected to the inner wall of the sliding groove 5. A base 7 is fixedly connected to the bottom surface of the support column 6. Locking bolts 8 are threaded onto the side of the columns 2, with the bottom surface of the locking bolts 8 fitting against the support column 6. A U-shaped frame 9 is bolted to the top surface of the base plate 3. The top of the U-shaped frame 9 is threaded with a threaded post 10. The bottom end of the threaded post 10 is rotatably connected to a lifting plate 11 via a bearing. The lifting plate 11 is slidably connected to the U-shaped frame 9. The bottom surface of the lifting plate 11 is fixedly connected with a pin 12. The top surface of the base plate 3 has a through hole 13. The inner wall of the through hole 13 is rotatably connected with a rotating rod 14. The top surface of the rotating rod 14 is fixedly connected with a locking disc 15. The pin 12 is engaged with the locking disc 15. The bottom surface of the rotating rod 14 is fixedly connected with a connecting plate 16. The bottom surface of the connecting plate 16 is fixedly connected with two universal wheels 17.

[0022] As an optional technical solution of this utility model, the length of the support column 6 is equal to the depth of the slide groove 5, and a number of locking holes 18 are opened through the top surface of the base 7. By controlling the length of the support column 6 extending out of the slide groove 5, not only can the caster wheel 17 be lifted off the ground, but the height of the isolation bracket can also be adjusted.

[0023] The side of the support column 6 is fixedly connected to the limiting shaft 19, and the side of the column 2 is provided with a through slot 20. The limiting shaft 19 is slidably connected to the column through the slot 20. When the support column 6 slides inside the slide groove 5, it will drive the limiting shaft 19 to slide inside the slot 20, which can limit the movement of the support column 6.

[0024] The thickness of the base plate 3 is equal to the length of the rotating rod 14. The locking plate 15 and the connecting plate 16 are slidably connected to the base plate 3. The top surface of the locking plate 15 has several snap-fit ​​holes 21. The pin 12 is slidably connected to the locking plate 15 through the snap-fit ​​holes 21. The connecting plate 17 is pushed to rotate around the rotating rod 14 until both casters 17 are directly below the base plate 3. Then the threaded post 10 is reversed, and the pin 12 is re-inserted into the snap-fit ​​holes 21 through the threaded transmission. This can store the two casters 17 and prevent them from being exposed and affecting pedestrian traffic.

[0025] A guide rod 22 is fixedly connected to the top surface of the lifting plate 11. The guide rod 22 is slidably connected to the U-shaped frame 9. The length of the guide rod 22 is equal to that of the threaded column 10.

[0026] A municipal isolation bracket works on the following principle:

[0027] 1): When it is necessary to use isolation brackets to isolate municipal construction sites, the column 2 can be pushed to move under the rolling of the caster wheel 17.

[0028] 2): After the isolation bracket moves to the use position, the locking bolt 8 can be rotated to move it away from the support column 6, which can release the lock on the support column 6. Then, the support column 6 is pulled down to make the base 7 contact the ground. By controlling the length of the support column 6 extending out of the slide groove 5, the caster wheel 17 can be lifted off the ground.

[0029] 3): Rotate the threaded column 10 to drive the lifting plate 11 upward until the pin 12 is completely out of the locking hole 21. Then the locking plate 15 can be released. At this time, the connecting plate 17 can be pushed to rotate around the rotating rod 14 until both casters 17 are directly below the base plate 3. Then reverse the threaded column 10 and drive the pin 12 to re-insert into the locking hole 21 through the threaded transmission. The two casters 17 can then be stored.

[0030] In summary, this municipal isolation support, when used to isolate a municipal construction site, allows the column 2 to be pushed and moved by the omnidirectional wheels 17. Each connecting plate 16 has two omnidirectional wheels 17 on its bottom surface, and the rolling of all four omnidirectional wheels 17 ensures stable movement of the isolation support, making it easier to transport and significantly reducing the workload of workers. Once the isolation support has reached its designated position, the locking bolt 8 can be rotated to move it away from the support column 6, releasing the lock on the support column 6. Then, the support column 6 can be pulled downwards to bring the base 7 into contact with the ground. By controlling the length of the support column 6 extending beyond the sliding groove 5, the... To lift the casters 17 off the ground, the isolation bracket can be installed more stably. After installing the base 7 on the ground using the locking pins through the locking holes 18, the threaded column 10 can be rotated to drive the lifting plate 11 upward until the pin 12 is fully moved out of the locking hole 21. Then the locking plate 15 can be released. At this time, the connecting plate 17 can be pushed to rotate around the rotating rod 14 until both casters 17 are directly below the base plate 3. Then the threaded column 10 is reversed, and the pin 12 is re-inserted into the locking hole 21 through the threaded transmission. This can store the two casters 17 and prevent them from being exposed and affecting pedestrian traffic.
