Description

Technical Field

[0001] The utility model relates to the technical field of guardrail plate installation, in particular to a clamping device for guardrail plates. Background Art

[0002] Guardrail is a very important form of clamping device for semi-rigid guardrail. It is also a continuous structure in which corrugated steel guardrails are spliced ​​together and supported by main columns. It mainly utilizes the deformation of soil foundation, columns, beams and endurance plates to absorb collision energy, and force out-of-control vehicles to change direction and return to the normal driving direction to prevent vehicles from running off the road, so as to protect vehicles and passengers and reduce losses caused by accidents.

[0003] Existing guardrails are mainly used on roadsides of highways or mountainous areas to prevent vehicles from running off the road in accidents and to play a buffering role. When installing guardrails, conventional straight sections can be installed directly, but when encountering a more curved road, the guardrails can only be bent manually. Since the guardrails have strong resistance to bending, manual installation is time-consuming and laborious. If you are not careful, the rebound of the guardrails can easily cause injuries to workers. Utility Model Content

[0004] The utility model aims to solve the disadvantages of the existing manual installation of curved road guardrails, which is time-consuming and labor-intensive, and proposes a clamping device for the guardrails.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping device for a guardrail plate comprises a threaded column, the outer wall of the threaded column is threadedly connected to a fixing block, the lower end dog of the fixing block is fixedly connected to a lower clamping claw, the front end of the fixing block is threadedly connected to a limiting cover, the outer wall of the limiting cover is slidably connected to an upper clamping claw, the outer wall of the threaded column is threadedly connected to a fixing column, the top end of the fixing column is fixedly connected to an upper mounting ring, the bottom end of the fixing column is fixedly connected to a mounting block, the mounting block is slidably connected to lower mounting rings that are symmetrically distributed, and the top end of the lower mounting ring is fixedly connected to a connecting block.

[0007] Preferably, the outer wall of the connecting block is threadedly connected with bolts, the outer walls of the upper mounting ring and the lower mounting ring are both provided with extrusion columns, and the outer walls of the extrusion columns are fixedly connected with a rotating block.

[0008] Preferably, a cylinder is fixedly connected to the mounting block, and the lower mounting ring is rotatably connected to the cylinder.

[0009] Preferably, the threaded column is fixedly connected to a handle away from the tail end, and a through hole is provided on the outer wall of the handle.

[0011] Preferably, a sliding groove is provided on the outer wall of the upper clamping claw, the sliding groove is slidably connected to the limiting cover, and the limiting cover and the threaded column do not contact each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, the upper mounting ring and the lower mounting ring can be fixed at the upper and lower positions of the road pile, and then the position of the clamping device can be adjusted by rotating the threaded column, the guardrail plate can be placed in the clamping device, and then the threaded column can be driven to rotate by rotating the handle. Under the condition of mutual restraint between the clamping device and the guardrail plate, and the mounting ring and the roadbed, the threaded column drives the guardrail plate to bend backward, so that the guardrail plate can be clamped and bent more easily, which saves time and effort in use and can also reduce the probability of worker injury.

[0014] 2. When the utility model is in use, the limit cover, bolts, extrusion columns, etc. can be used in coordination with each other, so that when encountering roadbeds or guardrails of different sizes, timely adjustments can be made to adapt to more situations, thereby greatly increasing the practicality of the device and making it easier to disassemble.

[0020] Reference Figure 1-Figure 3 A clamping device for a guardrail plate comprises a threaded column 1, the outer wall of the threaded column 1 is threadedly connected with a fixing block 2, the lower end dog of the fixing block 2 is fixedly connected with a lower clamping claw 3, the front end of the fixing block 2 is threadedly connected with a limiting cover 4, the outer wall of the limiting cover 4 is slidably connected with an upper clamping claw 5, the outer wall of the threaded column 1 is threadedly connected with a fixing column 6, the top end of the fixing column 6 is fixedly connected with an upper mounting ring 7, the bottom end of the fixing column 6 is fixedly connected with a mounting block 8, the mounting block 8 is slidably connected with lower mounting rings 9 which are symmetrically distributed, and the top end of the lower mounting ring 9 is fixedly connected with a connecting block 10.

[0021] Furthermore, the outer wall of the connection block 10 is threadedly connected with a bolt 11 , and the outer walls of the upper mounting ring 7 and the lower mounting ring 9 are both provided with an extrusion column 12 , and the outer wall of the extrusion column 12 is fixedly connected with a rotating block 13 .

[0022] Among them, the bolt 11 can control the opening and closing of the lower mounting ring 9, so that it can be easily disassembled after installation. The extrusion column 12, in cooperation with the rotating block 13, can make the entire device more firmly installed on the roadbed when encountering roadbeds of different sizes.

[0023] Furthermore, a cylinder 14 is fixedly connected to the mounting block 8 , and the lower mounting ring 9 is rotatably connected to the cylinder 14 .

[0024] The cylinder 14 is arranged inside the mounting block 8, and the separated lower mounting ring 9 is arranged on the cylinder 14. The lower mounting ring 9 rotates around the cylinder 14 to open a larger opening and free the device trapped in the roadbed.

[0025] Furthermore, a turning handle 15 is fixedly connected to the threaded column 1 away from the tail end, and a through hole 16 is opened on the outer wall of the turning handle 15 .

[0026] Among them, the cross-sectional area of ​​the turning handle 15 is larger than the cross-sectional area of ​​the threaded column 1, so that when rotating to the tail end, the fixing column 6 will not fall out of the device. After the through hole 16 is opened, the worker can use a long rod to rotate the threaded column 1 with the help of the through hole 16, which can save more effort.

[0027] Furthermore, a limiting block 17 is fixedly connected to the head end of the threaded column 1 .

[0028] The limiting block 17 is mainly used to limit the fixing column 6, the upper clamping claw 5 and the fixing block 2 from being out of position during rotation.

[0029] Furthermore, a sliding groove is provided on the outer wall of the upper clamping claw 5 , and the sliding groove is slidably connected to the limiting cover 4 , and the limiting cover 4 and the threaded column 1 do not contact each other.

[0030] Among them, the function of the slide groove is to adjust the height of the upper clamping claw 5, which can adapt to guardrail boards of different sizes, and the inner walls of the upper clamping claw 5 and the lower clamping claw 3 are provided with anti-slip pads to prevent the guardrail board from detaching due to wet and slippery surface.

[0031] Working principle: When the guardrail plate needs to be bent, first rotate the bolt 11, open the connecting block 10, move the lower mounting ring 9 to install it on the lower half of the roadbed, and then connect it again with the bolt 11. The upper mounting ring 7 can be directly put on the roadbed. When encountering roadbeds of different sizes, the rotating block 13 can be rotated to drive the extrusion column 12 to squeeze the roadbed to increase the friction between the two, and then rotate the limit cover 4 to adjust the height of the upper clamping claw 5 according to the size of the guardrail plate, and then place the guardrail plate between the lower clamping claw 3 and the upper clamping claw 5. Finally, rotate the handle 15, and the handle 15 drives the threaded column 1 to rotate, and the threaded column 1 drives the fixed block 2 to move backward to achieve the bending of the guardrail plate, so that the guardrail plate can be clamped and bent more easily at the same time. It is more time-saving and labor-saving to use, and the probability of worker injury can be reduced.
