Description

Technical Field

[0001] The present application relates to the field of protective fences, and in particular, to a protective fence used in the construction of a rotating bridge. Background Art

[0002] During the construction of the rotating bridge, in order to isolate the construction area from other surrounding areas and protect the construction area, a protective fence will be set up on the periphery of the construction area to surround the construction area.

[0003] Existing protective fences are generally in a fixed state, so that the columns and protective plates are in a vertically fixed state, such as a construction enclosure structure described in the authorization announcement number CN117449698B, wherein a protective fence structure is formed by the combination of a first side bracket, a second side bracket, a first protective assembly and an isolation plate. Regardless of whether the protective fence is hit or slowly pushed, since the fence is a fixed structure as a whole, once a vehicle hits the fence or pushes the fence, the protective fence will be dented or damaged, thereby causing unnecessary loss of the protective fence. Therefore, the present invention provides a protective fence for the construction of a rotating bridge. Summary of the invention

[0004] The main purpose of the present application is to provide a protective fence for the construction of a rotating bridge. By slowly pushing the guardrail and hitting the guardrail, the different performances of the guardrail in different states are utilized. When the vehicle slowly pushes the guardrail, the guardrail is tilted as a whole to prevent the vehicle from pushing the guardrail during the reversing process and causing unnecessary property losses. When the vehicle hits the guardrail, an instantaneous reverse support force is provided to force the vehicle to stop.

[0005] To achieve the above-mentioned purpose, the present application provides a protective fence for the construction of a rotating bridge, comprising a main support assembly and an upper protective plate hinged at equal intervals between two main support assemblies, wherein a lower protective plate is hinged at the bottom end of the upper protective plate, and two adjacent upper protective plates are hinged to each other through an articulated frame, and the main support assembly comprises:

[0006] The support base is fixed to the ground by expansion bolts, and a groove is provided at the top of the support base, and the rear end of the groove is connected to the outside, and hinge shafts are fixed on both side walls of the groove, and telescopic rods are sleeved on the hinge shafts;

[0007] The column is rotatably connected to the front end of the groove through a rotating shaft, and a sliding groove is opened in the lower half of the column, and a sliding block is slidably connected inside the sliding groove, and the other ends of the two telescopic rods are respectively hinged to the two ends of the sliding block, and the upper halves of both sides of the column are vertically fixed with hinged rods.

[0008] Preferably, both ends of the support base are provided with fixing holes for bolts to pass through.

[0009] Preferably, a built-in groove is provided at the bottom of the groove directly below the column, and a return spring 1 is arranged inside the built-in groove, and an arc-shaped limit block is fixedly connected to the top of the return spring 1, and arc-shaped grooves matching the arc-shaped limit block are provided at equal intervals at the bottom of the column along a quarter of its circumference.

[0010] Preferably, both left and right ends of the upper protective plate are provided with hinged through holes matching the hinged frame, and a second slide groove is provided on the back side of the upper protective plate, and a first slide groove is provided on the back side of the lower protective plate.

[0011] Preferably, a support bracket assembly is provided on the back side of the lower protective plate and the upper protective plate, wherein the support bracket assembly includes a support foot supported on the ground, the top of the support foot is hinged with a first sleeve and a second sleeve respectively, and the first sleeve and the second sleeve are each provided with a second return spring, a telescopic guide rod is provided on the inner side of the second return spring, and the second return spring and the other end of the telescopic guide rod provided inside the first sleeve and the second sleeve are respectively connected to the first rod and the second rod, and a slider that can slide along the second slide groove and the first slide groove is respectively hinged at the other end of the first rod and the second rod.

[0012] Preferably, the telescopic rod is formed by a combination of a square sleeve and a square sleeve rod, wherein the bottom end of the square sleeve rod is connected to the inner bottom end of the square sleeve via a spring.

[0013] The benefits of the present application are as follows: first, when a vehicle pushes the guardrail slowly, for example, the vehicle pushes the guardrail in the reversing state, due to the slow speed of the vehicle, the spring inside the telescopic rod and the second return spring inside the supporting bracket assembly will not instantly release the elastic potential energy, thus giving the spring inside the telescopic rod and the second return spring inside the supporting bracket assembly sufficient reaction time, so that the spring and the second return spring can be slowly compressed. During the compression process of the spring and the second return spring, on the one hand, due to the slow speed of the vehicle pushing the guardrail, on the other hand, the length of the telescopic assembly inside the telescopic rod and the supporting bracket assembly changes, so that the sliding block inside the sliding groove and the sliders inside the second and first slide slowly from top to bottom along their corresponding interiors, so that the guardrail as a whole rotates along the rotation axis, thereby tilting the guardrail as a whole, avoiding the vehicle pushing the guardrail during the reversing process, causing unnecessary property losses, and at the same time explaining that if the loaded vehicle is too large to enter through the gate, the rear of the vehicle can also be extended to the inside of the construction area for unloading by slowly reversing;

[0014] Secondly, when a vehicle hits the guardrail, for example, a vehicle hits the guardrail while driving and causes a car accident, due to the relatively fast speed of the vehicle, the impact force generated at the moment of hitting the guardrail will be instantly transmitted to the internal spring of the telescopic rod and the internal reset spring 2 of the support bracket assembly, so that the elastic potential energy generated by the internal spring of the telescopic rod and the internal reset spring 2 of the support bracket assembly is instantly released, and recoils in the direction of the impact force of the vehicle, forcing the vehicle to stop. At the same time, since the sliding groove and the first and second slide grooves are distributed along the height direction, and the two sliders and the sliding block are initially in the top of the first, second and sliding grooves, when the elastic potential energy is instantly released, an upward reverse supporting force is provided to the slider and the sliding block, thereby increasing the reverse supporting force of the instantaneous impact of the vehicle.

[0030] See also Figure 1-Figure 7 As shown, the present embodiment provides a protective fence for the construction of a rotating bridge, comprising a main support assembly 100 and an upper protective plate 400 which is hinged at equal intervals between two main support assemblies 100, wherein a lower protective plate 200 is hinged at the bottom end of the upper protective plate 400, and two adjacent upper protective plates 400 are hinged to each other through a hinge frame 300, and the main support assemblies 100 are distributed at intervals, thereby enclosing the construction area of ​​the rotating bridge, and then the hinge frame 300 and the hinge rod 105 on the main support assembly 100 cooperate with the hinge through hole 401 on the upper protective plate 400 to form a protective fence, in this process, the upper protective plates 400 are hinged to each other, so that the upper protective plates 400 can be rotated along the hinge frame 300 and the hinge rod 105, thereby realizing the arbitrary change of the fence encirclement angle, and at the same time facilitating the folding and storage of the guardrail;

[0031] The main support assembly 100 includes:

[0032] The support base 101 is fixed to the ground by expansion bolts, and a groove 108 is provided at the top of the support base 101, and the rear end of the groove 108 is connected to the outside, and hinge shafts 107 are fixed on both side walls of the groove 108, and telescopic rods 106 are sleeved on the hinge shafts 107;

[0033] The column 104 is rotatably connected to the front end of the groove 108 through a rotating shaft 114, and a sliding groove 102 is opened in the lower half of the column 104, and a sliding block 103 is slidably connected inside the sliding groove 102, and the other ends of the two telescopic rods 106 are respectively hinged to the two ends of the sliding block 103, and the upper halves of both sides of the column 104 are vertically fixed with hinged rods 105.

[0034] In this embodiment, the guardrail is slowly pushed by the vehicle and hits the guardrail, and the different performances of the guardrail in different states are utilized. When the vehicle slowly pushes the guardrail, the guardrail is tilted as a whole, so as to prevent the vehicle from pushing the guardrail during the reversing process and causing unnecessary property damage. When the vehicle hits the guardrail, an instantaneous reverse support force is provided to force the vehicle to stop.

[0035] In this embodiment, both ends of the support base 101 are provided with fixing holes 109 for bolts to pass through. When in use, the support base 101 is fixed on the ground by the bolts passing through the fixing holes 109 and cooperating with the pre-installed expansion sleeves.

When in use, during the rotation of the guardrail along the rotating shaft 114, the arc-shaped limit block 112 slides along the inside of the built-in groove 110 during the rotation of the guardrail, and the arc-shaped limit block 112 is reset by the return spring 111, thereby limiting the column 104.

[0037] like Figure 5 as well as Figure 6 As shown, in this embodiment, both left and right ends of the upper protective plate 400 are provided with hinged through holes 401 matching the hinged frame 300, and a slide groove 2 402 is provided on the back of the upper protective plate 400, and a slide groove 1 201 is provided on the back of the lower protective plate 200. When in use, the hinged through holes 401 on the hinged frame 300 cooperate with each other to connect the upper protective plates 400 to form a fence.

[0038] like Figure 1 , Figure 5 as well as Figure 6As shown, in this embodiment, a support bracket assembly 500 is arranged on the back of the lower protective plate 200 and the upper protective plate 400, wherein the support bracket assembly 500 includes a support foot 506 supported on the ground, and the top of the support foot 506 is hinged with a first sleeve 503 and a second sleeve 505, respectively, and the first sleeve 503 and the second sleeve 505 are both provided with a return spring 2 507 inside, and a telescopic guide rod 508 is arranged on the inner side of the return spring 2 507. By setting the telescopic guide rod 508, it can be ensured that the sleeve rod slides stably inside the sleeve, and a telescopic guide rod 508 is arranged inside the first sleeve 503 and the second sleeve 505. The other ends of the return spring 507 and the telescopic guide rod 508 are respectively connected to the first set rod 502 and the second set rod 504, and the other ends of the first set rod 502 and the second set rod 504 are respectively hinged with sliders 501 that can slide along the second slide groove 402 and the first slide groove 201. When in use, the supporting feet 506 are set on the ground and then the two sliders 501 are respectively slidably connected to the inside of the second slide groove 402 and the first slide groove 201. At the same time, the upper protective plate 400 is reversely supported by the first sleeve 503 and the first set rod 502, and the lower protective plate 200 is reversely supported by the second sleeve 505 and the second set rod 504.

[0039] In this embodiment, the telescopic rod 106 is formed by a combination of a square sleeve and a square sleeve rod, wherein the bottom end of the square sleeve rod is connected to the bottom end of the square sleeve through a spring. When in use, the telescopic rod 106 supports the column 104.

[0040] In summary:

[0041] First, the main support assemblies 100 are arranged at intervals to enclose the construction area of ​​the rotating bridge, and then the hinged frame 300 and the hinged rod 105 on the main support assembly 100 cooperate with the hinged through hole 401 on the upper protective plate 400 to form a protective fence. In this process, the upper protective plates 400 are hinged to each other, so that the upper protective plates 400 can be rotated along the hinged frame 300 and the hinged rod 105, so as to realize the arbitrary change of the fence encirclement angle, and at the same time facilitate the folding and storage of the guardrail;

[0042] Subsequently, during the use of the guardrail, when a vehicle slowly pushes the guardrail, for example, the vehicle pushes the guardrail in reverse, due to the slow speed of the vehicle, the spring inside the telescopic rod 106 and the second return spring 507 inside the support bracket assembly 500 will not instantly release elastic potential energy, thereby giving the spring inside the telescopic rod 106 and the second return spring 507 inside the support bracket assembly 500 enough reaction time to allow the spring and the second return spring 507 to be slowly compressed. During the compression process of the spring and the second return spring 507, on the one hand, due to the slow speed of the vehicle pushing the guardrail, on the other hand, the length of the telescopic rod 106 and the telescopic assembly inside the support bracket assembly 500 changes, causing the sliding block 103 inside the sliding groove 102 and the second slide groove 402 to be compressed. The slider 501 inside the slide groove 201 slides slowly from top to bottom along its corresponding interior, so that the guardrail as a whole rotates along the rotation axis 114, thereby tilting the guardrail as a whole to prevent the vehicle from pushing the guardrail during the reversing process and causing unnecessary property losses. At the same time, during the rotation of the guardrail along the rotation axis 114, the arc groove 113 and the arc limit block 112 cooperate with each other, so that during the rotation of the guardrail, the arc limit block 112 slides along the inside of the built-in groove 110 and is reset by the reset spring 111, thereby limiting the column 104. At the same time, it is explained that if the loaded vehicle is too large to enter through the gate, the rear of the vehicle can also be extended to the inside of the construction area for unloading by slowly reversing;

[0043] At the same time, during the use of the guardrail, when a vehicle hits the guardrail, for example, a vehicle hits the guardrail during driving and causes a traffic accident, due to the relatively fast speed of the vehicle, the impact force generated at the moment of hitting the guardrail will be instantly transmitted to the internal spring of the telescopic rod 106 and the internal return spring 2 507 of the support bracket assembly 500, so that the elastic potential energy generated by the internal spring of the telescopic rod 106 and the internal return spring 2 507 of the support bracket assembly 500 is instantly released, and recoils in the direction of the impact force of the vehicle, forcing the vehicle to stop. At the same time, since the sliding groove 102 and the sliding groove 1 201 and the sliding groove 2 402 are all distributed in the height direction, and the two sliders 501 and the sliding block 103 are initially at the top of the sliding groove 1 201, the sliding groove 2 402 and the sliding groove 102, when the elastic potential energy is instantly released, an upward reverse supporting force is provided to the slider 501 and the sliding block 103, thereby increasing the reverse supporting force of the instantaneous impact of the vehicle.
