Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, and more specifically, to a protective fence for railway construction. Background Technology

[0002] Protective fencing for railway construction is a temporary safety facility set up to ensure the safety and standardized management of the construction site and to protect the surrounding environment. Its main function is to prevent unauthorized personnel from entering the construction area, ensure the safety of construction workers, and effectively isolate the construction area from the external environment to reduce external interference.

[0003] Chinese Patent Publication No. CN214463240U discloses a protective fence for railway construction. This patent utilizes a U-shaped support plate to securely place the first and second bases in suitable positions. Alternatively, the U-shaped support plate can be placed on the railway rail near the construction site, using a magnetic plate to attract the top of the rail, thus ensuring the stable placement of the first and second bases and preventing tipping. This effectively protects the construction site. By activating a water pump, clean water from the tank is atomized and sprayed from multiple first and second atomizing nozzles. The atomized water mist collides with dust in the air and condenses into water droplets, which fall to the ground. The multiple atomizing nozzles allow for a wider spray range, effectively reducing dust and purifying the air around the work area, thus improving air quality.

[0004] However, the protective fences mentioned in the aforementioned patents can only serve to reduce dust and purify the air. Most existing protective fences have sprinkler heads for water spraying, and their overall function is relatively simple. Moreover, most existing protective fences are fixed in construction areas. Without sufficient warning signs, in dim environments, not only are pedestrians prone to collisions, but some novice drivers may also hit the fences when encountering them in low light conditions, which can easily cause personal injury and vehicle damage. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a protective fence for railway construction. It can achieve the purpose of buffering and weakening the impact force through the main cushioning pad, and at the same time, it uses the lifting rod to raise the secondary guardrail frame, so as to increase the height of the overall protective fence, thereby effectively playing the role of protection and anti-collision.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A protective fence for railway construction includes a main guardrail frame. A pair of base posts are fixedly connected to the lower end of the main guardrail frame. A buffer main pad is fixedly connected to the middle of the main guardrail frame. A secondary guardrail frame is slidably connected to the rear end of the main guardrail frame. A buffer secondary pad is fixedly connected to the middle of the secondary guardrail frame. The buffer secondary pad has the same structure as the buffer main pad. A pair of control slots are opened on one end of the main guardrail frame near the secondary guardrail frame, and the pair of control slots are respectively located on the left and right sides of the secondary guardrail frame. Limit blocks are slidably connected in the control slots and are fixedly connected to the secondary guardrail frame. A lifting rod is fixedly connected to the lower inner wall of the control slot, and the upper end of the lifting rod is fixedly connected to the limit block. The buffer main pad buffers and weakens the impact force, while the lifting rod raises the secondary guardrail frame, increasing the overall height of the protective fence, thereby effectively providing protection and preventing impacts.

[0010] Furthermore, the main buffer pad includes multiple hexagonal buffer blocks, all of which are located in the middle of the main guardrail frame. An elastic mesh rope runs through the middle of each of the multiple hexagonal buffer blocks, and the elastic mesh rope is fixedly connected to the inner wall of the main guardrail frame. The multiple hexagonal buffer blocks can buffer the impact force, and the elasticity of the elastic mesh rope can be used to reset the hexagonal buffer blocks that protrude due to the impact.

[0011] Furthermore, the hexagonal buffer block includes a buffer bag, which is located in the middle of the main guardrail frame. A buffer airbag is fixedly connected to the end of the buffer bag away from the secondary guardrail frame. The buffer bag is filled with antifreeze gel and buffer gravel. The buffer airbag can reduce injuries to the personnel who are impacted, while the antifreeze gel and buffer gravel in the buffer bag can effectively buffer high impacts, thereby maximizing the reduction of personnel injuries and vehicle damage caused by vehicle collisions.

[0012] Furthermore, a frame pad is fixedly connected to the end of the main guardrail away from the secondary guardrail. A pair of elastic protective nets are fixedly connected to the inner walls of both the main guardrail and the secondary guardrail. The main buffer pad and the secondary buffer pad are located between the two pairs of elastic protective nets. The frame pad protects the unprotected edge of the main guardrail, maximizing the protection of the fence. At the same time, the elastic protective nets not only provide a certain buffering effect, but also limit and wrap the main buffer pad and the secondary buffer pad, preventing them from detaching from the main guardrail and the secondary guardrail due to excessive force.

[0013] Furthermore, a pair of warning lights are fixedly connected to the upper end of the main guardrail, and a sprinkler head is fixedly connected to the upper end of the secondary guardrail. The sprinkler head can spray water to reduce dust in the construction area, while the warning lights can be used to warn pedestrians in the construction area and prevent them from crashing into the work.

[0014] Furthermore, a pair of grooves are provided on the left end of the main guardrail frame, and a pair of protrusions that match the grooves are fixedly connected to the right end of the main guardrail frame. By connecting the protrusions with the grooves, the multiple guardrails are firmly connected, and when a single guardrail is impacted, it can be cushioned by the support of the other guardrails.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0018] (2) In this scheme, the main buffer pad includes multiple hexagonal buffer blocks. The multiple hexagonal buffer blocks are all located in the middle of the main guardrail frame. An elastic mesh rope runs through the middle of the multiple hexagonal buffer blocks, and the elastic mesh rope is fixedly connected to the inner wall of the main guardrail frame. The impact force can be buffered by the multiple hexagonal buffer blocks. At the same time, the elasticity of the elastic mesh rope can be used to reset the hexagonal buffer blocks that protrude due to the impact.

[0019] (3) In this scheme, the hexagonal buffer block includes a buffer bag, which is located in the middle of the main guardrail. The buffer bag is fixedly connected to a buffer airbag at the end away from the secondary guardrail. The buffer bag is filled with antifreeze gel and buffer gravel.

A pair of elastic protective nets are fixedly connected to the inner walls of the main guardrail frame and the secondary guardrail frame. The buffer main pad and the buffer secondary pad are located in the middle of the two pairs of elastic protective nets. The frame pad protects the unprotected edge part of the main guardrail frame to maximize the protection of the fence. At the same time, the elastic protective net can not only play a certain buffering role, but also limit and wrap the buffer main pad and the buffer secondary pad to prevent them from being detached from the main guardrail frame and the secondary guardrail frame due to excessive force.

[0032] Example 1:

[0033] Please see Figures 1-4 A protective fence for railway construction includes a main guardrail frame 1, a pair of base posts 2 fixedly connected to the lower end of the main guardrail frame 1, a buffer main pad 3 fixedly connected in the middle of the main guardrail frame 1, a secondary guardrail frame 4 slidably connected to the rear end of the main guardrail frame 1, a buffer secondary pad 5 fixedly connected in the middle of the secondary guardrail frame 4, the buffer secondary pad 5 having the same structure as the buffer main pad 3, a pair of control grooves 6 opened at one end of the main guardrail frame 1 near the secondary guardrail frame 4, and the pair of control grooves 6 being located on the left and right sides of the secondary guardrail frame 4 respectively, a limit block 7 slidably connected in the control groove 6, and the limit block 7 being fixedly connected to the secondary guardrail frame 4, a lifting rod 8 fixedly connected to the lower inner wall of the control groove 6, and the upper end of the lifting rod 8 being fixedly connected to the limit block 7. The buffer main pad 3 buffers and weakens the impact force received, and at the same time, the lifting rod 8 is used to lift the secondary guardrail frame 4, so that the overall protective fence is raised, thereby effectively achieving the effect of protection and anti-collision.

[0034] The main buffer pad 3 includes multiple hexagonal buffer blocks 31, which are all located in the middle of the main guardrail frame 1. An elastic mesh rope 32 runs through the middle of the multiple hexagonal buffer blocks 31, and the elastic mesh rope 32 is fixedly connected to the inner wall of the main guardrail frame 1. The multiple hexagonal buffer blocks 31 can buffer the impact force, and the elasticity of the elastic mesh rope 32 can reset the hexagonal buffer blocks 31 that protrude after impact.

[0035] The hexagonal buffer block 31 includes a buffer bag 311, which is located in the middle of the main guardrail frame 1. A buffer airbag 312 is fixedly connected to the end of the buffer bag 311 away from the secondary guardrail frame 4. The buffer bag 311 is filled with antifreeze gel 313 and buffer gravel 314. The buffer airbag 312 can reduce injuries to the personnel who are hit, while the antifreeze gel 313 and buffer gravel 314 in the buffer bag 311 can effectively buffer high impacts, thereby maximizing the reduction of personnel injuries and vehicle damage caused by vehicle collisions.

[0036] A frame pad 9 is fixedly connected to the end of the main guardrail frame 1 away from the secondary guardrail frame 4. A pair of elastic protective nets 10 are fixedly connected to the inner walls of both the main guardrail frame 1 and the secondary guardrail frame 4. The main buffer pad 3 and the secondary buffer pad 5 are located between the two pairs of elastic protective nets 10. The frame pad 9 protects the unprotected edge of the main guardrail frame 1 to maximize the protection of the fence. At the same time, the elastic protective nets 10 can not only play a certain buffering role, but also limit and wrap the main buffer pad 3 and the secondary buffer pad 5 to prevent them from detaching from the main guardrail frame 1 and the secondary guardrail frame 4 due to excessive force.

[0037] A pair of warning lights 12 are fixedly connected to the upper end of the main guardrail frame 1, and a sprinkler head 11 is fixedly connected to the upper end of the secondary guardrail frame 4. The sprinkler head 11 can spray water to reduce dust in the construction area, while the warning lights 12 can be used to warn pedestrians in the construction area and prevent them from crashing into it.

[0038] The left end of the main guardrail frame 1 has a pair of grooves, and the right end of the main guardrail frame 1 is fixedly connected with a pair of protrusions that match the grooves. The protrusions and grooves are connected to each other to make the multiple guardrails firmly connected. When a single guardrail is hit, it can be cushioned by the support of the other guardrails.

[0039] When using it, please refer to Figures 1-4 When pedestrians or vehicles collide with the fence, the impact force can be weakened by the protection of multiple hexagonal buffer blocks 31, thus playing a protective role. Furthermore, when the height of the main guardrail frame 1 is insufficient, a pair of lifting rods 8 are used to raise the limiting block 7, causing the secondary guardrail frame 4 to rise and increase the height of the main guardrail frame 1, thereby maximizing the protection of the fence. Compared with traditional railway construction protective fences, this utility model can achieve the purpose of buffering and weakening the impact force through the buffer main pad 3, and at the same time, use the lifting rods 8 to raise the secondary guardrail frame 4, thereby increasing the overall height of the protective fence, thus effectively playing a protective and anti-collision role.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
