Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of highway construction, in particular to a highway construction protection device. BACKGROUND

[0002] When a road section needs to be repaired or newly built, a protection device is usually erected to enclose the construction site, which can ensure the safety of the surrounding environment during construction, and also has a certain noise reduction effect.

[0003] For example, Chinese patent publication CN112983118A discloses a highway construction safety protection system, which belongs to the field of building construction and includes a plurality of protection units connected in sequence. Each protection unit includes a protection base and a support rod arranged on the top of the protection base. A connecting chain is arranged between two adjacent protection bases, and a plurality of connecting guardrails are arranged between two adjacent support rods. One of the connecting guardrails is provided with a warning sign. A plurality of anti-collision bases are arranged on the protection base along the height direction of the protection base. The anti-collision base is provided with a first buffer assembly on the side away from the protection base. A second buffer assembly is arranged between each anti-collision base and the protection base. The protection device can improve the protection performance of the construction site and ensure the safety of the workers during construction.

[0004] The application sets a plurality of buffer assemblies on the front side of the anti-collision base to achieve buffering. However, when the anti-collision base tilts to one side, the back side of the anti-collision base lacks corresponding support force. Once the anti-collision base tilts, the entire device will quickly collapse, thereby losing the protection effect and causing the overall loss of the protection device, which has certain use limitations.

[0005] Therefore, it is necessary to provide a highway construction protection device to solve the above technical problems. SUMMARY

[0006] The present application aims to provide a highway construction protection device to solve the problems raised in the background.

[0007] To achieve the above-mentioned purpose, a highway construction protection device is designed, which can provide support force to the tilted side of the anti-collision base when the anti-collision base tilts to one side.

[0008] Based on the above idea, the present application provides the following technical solution: a highway construction protection device, including a base, a front support assembly corresponding to the collision piece is arranged on one side of the base, and a rear support assembly fixedly connected with the front support assembly is arranged on the top of the base; when the collision piece contacts the front support assembly, the front support assembly can be pushed to relatively approach the base, and when the front support assembly moves, the rear support assembly can be rotated to the other side of the base, so that the rear support assembly abuts against the ground on the other side of the base.

[0009] As a further scheme of the present application: the front support assembly comprises a support rod in sliding fit with the base and fixed connection with the rear support assembly, the end of the support rod away from the base is fixedly installed with a partition plate, the surface of the partition plate away from the support rod is fixedly installed with a cushion layer, and the outer surface of the support rod is sleeved with a first spring.

[0010] As a further scheme of the present application: the number of the support rods is several and they are equidistantly arranged from top to bottom, and the length dimension of the partition plate in the up-down direction is matched with the length dimension of the base in the up-down direction.

[0011] As a further scheme of the present application: the rear support assembly comprises a round rod rotatably installed on the base, the outer surface of the round rod is fixedly sleeved with a shell in active fit with the top surface of the base, the outer surface of the round rod and the base are sleeved with a torsion spring, and the outer surface of the round rod is fixedly wound with a traction rope in fixed connection with the support rod.

[0012] As a further scheme of the present application: when the support rod is relatively close to the base, the traction rope can be released, so that the round rod drives the shell to rotate away from the partition plate on one side of the base under the action of the torsion spring.

[0013] As a further scheme of the present application: the rotation base point of the round rod and the base is located on the side of the base away from the partition plate, so that the shell can be completely fit with the side of the base away from the partition plate after the round rod rotates.

[0014] As a further scheme of the present application: the bottom of the base is fixedly installed with a plug rod which can be inserted into the ground.

[0015] As a further scheme of the present application: the side of the partition plate away from the partition plate is rotatably provided with an auxiliary assembly, and the end of the support rod is fixedly installed with a top rod in abutment with the auxiliary assembly; when the support rod is close to the base, the top rod can drive the auxiliary assembly to move out of the base.

[0016] As a further scheme of the present application: the auxiliary assembly comprises a cover in rotatable connection with the partition plate and in abutment with the top rod, the inside of the cover is elastically connected with a side plate through a second spring, and the cover and the side plate are in parallel with the base.

[0017] As a further scheme of the present application: the surface of the shell is provided with a groove for the cover to be placed in, and when the cover is located in the groove, the surface of the cover away from the partition plate is flush with the surface of the base away from the partition plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation between the base, the front support assembly, and the rear support assembly, when the collision member abuts against the front side of the base, the rear support assembly can rotate and abut against the ground behind the base; when the collision member abuts against the rear side of the base, the bottom surface of the front support assembly can abut against the ground in front of the base. That is, regardless of whether the collision member contacts the front or rear side of the base, effective support can be achieved for the base. The multi-level protection formed by the front and rear support assemblies can effectively improve the anti-tipping effect of the base and ensure the long-term stable use of the base and the device as a whole. At the same time, the rotational design of the rear support assembly along the base allows it to be folded after use, which facilitates the transportation of the entire device and reduces the space occupied, making it more practical.

DETAILED DESCRIPTION

[0031] Embodiment one:

[0032] Referring to Figures 1 to 5 The embodiment of the present application provides a highway construction protection device, which is mainly used for improving the anti-toppling performance of the protection device as a whole, thereby achieving the purpose of long-term stable use. The device comprises a base 1, the front side of the base 1 is provided with a front support assembly 2 in direct contact with a collision piece, and the top of the base 1 is provided with a rear support assembly 3 fixedly connected with the front support assembly 2.

[0033] When in use, the base 1 is inserted into the ground to form fixation, and when the collision piece contacts the front support assembly 2, the front support assembly 2 can be pushed to relatively approach the base 1, and the front support assembly 2 can make the rear support assembly 3 rotate to the rear side of the base 1 when relatively moving, and the rotated rear support assembly 3 can abut against the ground behind the base 1, thereby forming effective support for the base 1 and avoiding the continuous toppling of the base 1.

[0034] Further, when the number of the base 1 is several (two in the figure), the adjacent two bases 1 are synchronously moved through the connecting piece 4. The connecting piece 4 is detachably connected with the base 1, which can facilitate the transportation and rapid assembly of the base 1 and prolong the protection range after assembly. Moreover, the connecting piece 4 can improve the overall protection performance, because when the collision piece contacts one of the front support assemblies 2 to make one of the bases 1 tilt, the base 1 will drive the adjacent base 1 to synchronously move through the connecting piece 4, so that the resistance of the base 1 to toppling is increased.

[0035] In the above structure, the connecting piece 4 can be a soft rope, a soft tube or an elastic connecting rod, etc., to adapt to the different corresponding angle requirements between the adjacent two bases 1, which are all mature technologies and will not be described in detail here.

[0036] Referring to Figure 2 and Figure 3In the embodiment, preferably, the front support assembly 2 comprises a support rod 203 reciprocally slidable relative to the front side of the base 1 and fixedly connected with the rear support assembly 3, a front end of the support rod 203 is fixedly installed with a partition plate 201, the partition plate 201 has a certain length in the up-down direction, of course, slightly smaller than the length of the base 1 in the up-down direction, and a front side of the partition plate 201 is fixedly installed with a cushion layer 202. The cushion layer 202 is elastic and can be planar or arc-shaped convex relative to the front side of the partition plate 201.

[0037] When the impact member moves towards the base 1, the cushion layer 202 can be directly contacted, the first wave force is absorbed by the cushion layer 202, and the partition plate 201 and the support rod 203 are close to the base 1. In order to realize the subsequent automatic reset of the partition plate 201 and the support rod 203, a first spring 204 is sleeved on the outer surface of the support rod 203. In order to improve the support effect of the partition plate 201, the number of support rods 203 can be correspondingly increased, and in the embodiment, the number of support rods 203 is three and arranged equidistantly from top to bottom.

[0038] In the above structure, the rear support assembly 3 can be fixedly connected with one of the support rods 203, and in the embodiment, the uppermost support rod 203 is connected. When the uppermost support rod 203 is close to the base 1, the rear support assembly 3 can be driven to rotate towards the rear side of the base 1, so that the rear support assembly 3 is abutted with the ground behind the base 1.

[0039] Referring to Figure 2 and Figure 5 In the embodiment, preferably, the rear support assembly 3 comprises a round rod 303 rotatably installed on the base 1, a shell 301 falling on the top surface of the base 1 is fixedly sleeved on the outer surface of the round rod 303, and a sliding plate 302 is slidably installed in the interior of the shell 301 in the up-down direction. The outer surface of the round rod 303 and the base 1 are sleeved with a torsion spring (not shown in the figure), and the torsion spring makes the round rod 303 drive the shell 301 to have a tendency to rotate towards the rear side of the base 1.

[0040] In order to realize the initial limiting of the round rod 303, a traction rope 304 fixedly connected with the uppermost support rod 203 is further wound on the outer surface of the round rod 303, the first spring 204 drives the support rod 203 to move outwardly relative to the base 1 and pull the traction rope 304, so that the round rod 303 drives the shell 301 to be in a vertical state. Of course, the traction rope 304 can be fixedly connected with other support rods 203, and the working process is the same.

[0041] It should be noted that the rotating force of the torsion spring acting on the round rod 303 is smaller than the pushing force of the plurality of first springs 204 on the support rods 203. At this time, the arrangement of the plurality of support rods 203 in combination with the first springs 204 can not only effectively support the partition plate 201, but also provide sufficient force to the traction rope 304 to ensure that the round rod 303 drives the shell 301 to keep corresponding to the base 1 in the initial state.

[0042] In the above structure, the front and rear surfaces of the shell 301 are in an idle state. In actual use, warning slogans can also be installed. The front and rear surfaces of the shell 301 are smooth, and the installation of the warning slogans is more convenient. At the same time, the arrangement of the shell 301 also ensures the height requirement of the protection device. The slide plate 302 has a certain gravity, which can increase the overall weight of the device to improve stability, and can immediately slide out to form support with the ground.

[0043] In order to ensure the supporting force, a telescopic spring (not shown in the figure) can be fixedly installed between the inner bottom wall of the shell 301 and the bottom surface of the slide plate 302; or the surface of the shell 301 away from the round rod 303 can be in contact with the ground after the shell 301 is rotated based on the base 1. At this time, the length dimension of the shell 301 in the up-down direction needs to be increased correspondingly.

[0044] Referring to Figure 2 , Figure 4 and Figure 5 , in the present embodiment, preferably: the bottom surface of the base 1 is fixedly installed with a plug rod 101 that can be inserted into the ground, the top surface of the base 1 is provided with a notch 102 for rotating and arranging the round rod 303, and the front side of the base 1 is provided with a sliding groove 103 for reciprocating sliding of the support rod 203; at the same time, the traction rope 304 extends from the sliding groove 103 into the notch 102 and is fixedly wound around the round rod 303.

[0045] In the present embodiment, the arrangement of the notch 102 makes the rotation of the round rod 303 driving the shell 301 unable to form a corresponding fit with the rear surface of the base 1, i.e. the maximum rotation angle is less than 180 degrees. Correspondingly, the rotation point of the round rod 303 and the base 1 can be arranged on the rear surface of the base 1 (the round rod 303 can be installed by arranging two protrusions on the rear surface of the base 1), at this time the shell 301 can be aligned with the rear surface of the base 1 after rotation; the advantages of the above design are: forming a rotating fit folding, which can facilitate overall transportation and reduce overall space occupation.

[0046] In the above structure, after the shell 301 is folded and attached to the rear surface of the base 1, a lock catch can be additionally installed between the shell 301 and the base 1 to avoid opening and resetting under the action of the plurality of first springs 204; wherein the lock catch is an existing mature technology, which will not be described in detail here. If the lock catch is not set, the base 1 can be attached one by one after being folded in the shell 301, and the mutual pushing force and extrusion force can be used to avoid the shell 301 from opening.

[0047] In use, first, the base 1 is relatively fixed to the ground through the insertion rod 101, and the plurality of bases 1 are arranged in a row through the connecting piece 4; when the collision piece contacts the cushion layer 202 on the front side of the base 1, the cushion layer 202 can drive the baffle 201 and the support rod 203 to move close to the base 1 and extrude the first spring 204, and the support rod 203 releases the traction rope 304 when moving, so that the round rod 303 drives the shell 301 to rotate to the rear side of the base 1. When the shell 301 rotates more than 90 degrees, the sliding plate 302 can automatically slide out of the shell 301 under the action of gravity and abut against the ground behind the base 1, so as to realize effective support of the base 1.

[0048] In actual use, if the collision piece contacts the rear side of the base 1, the side of the baffle 201 of the base 1 will be inclined, and at this time, the bottom of the baffle 201 with a longer length can abut against the ground in front of the base 1, so as to realize effective support of the base 1.

[0049] In summary, through the cooperation of the baffle 201, the traction rope 304, the shell 301 and the base 1 and the like, when the collision piece abuts against the front side of the base 1, the shell 301 can be rotated and the sliding plate 302 can automatically slide out and abut against the ground behind the base 1, and when the collision piece abuts against the rear side of the base 1, the bottom surface of the baffle 201 can abut against the ground in front of the base 1; that is, no matter whether the collision piece contacts the front side or the rear side of the base 1, effective support of the base 1 can be realized, the front and rear multi-stage protection of the baffle 201 and the sliding plate 302 greatly improves the anti-toppling effect of the base 1, and ensures long-term stable use of the base 1 and the whole device. At the same time, the rotation design of the shell 301 along the base 1 can form folding after use, which is convenient for transportation of the whole device, can also reduce the occupied space, and the whole device has higher practicability.

[0050] Embodiment two:

[0051] Please refer to Figures 1 to 8Based on Embodiment 1, to further improve the anti-tipping effect of the base 1, an auxiliary component 5 is rotatably installed on the side of the base 1 away from the partition 201 (rear surface), and a top rod 205 is fixedly installed at the rear end of the intermediate support rod 203 to abut against the auxiliary component 5. When the collision component causes the support rod 203 to approach the base 1, the top rod 205 can drive the auxiliary component 5 to rotate out from the rear surface of the base 1, at which time the auxiliary component 5 can abut against the bottom surface behind the base 1. The advantage of the above design is that the movement of the auxiliary component 5 does not require the support rod 203 to move a large distance.

[0052] Furthermore, a groove is provided on the rear surface of the housing 301 for the placement of the auxiliary component 5. At this time, the groove is connected with the sliding groove 103 for installing the intermediate support rod 203 to facilitate the movement of the top rod 205.

[0053] Reference Figure 7 and Figure 8 In this embodiment, preferably, the auxiliary component 5 includes a cover 501 rotatably connected to the groove and abutting against the top rod 205. A side plate 502 is elastically connected inside the cover 501 via a second spring 503. Under the action of the second spring 503, the side plate 502 tends to move downwards along the cover 501. Initially, the cover 501 and the side plate 502 are parallel to the rear surface of the base 1. If the top rod 205 moves towards the rear of the base 1, it can push the cover 501 to rotate out from the rear of the base 1. At this time, the side plate 502 extends out from inside the cover 501 under the action of the second spring 503 and abuts against the ground behind the base 1.

[0054] Of course, the top rod 205 can also be fixedly connected to other support rods 203, as long as the upper and lower positions of the cover 501 are adjusted accordingly, or the position of the cover 501 is not changed but the length and shape of the top rod 205 are adjusted instead.

[0055] In use, the partition 201, traction rope 304, and housing 301 provide support by abutting against the ground on the tilted side of the base 1. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference lies in that when the impact component contacts the padding layer 202, the support rod 203 moves into the slide groove 103. At this time, the top rod 205 moves synchronously to push out the cover 501, causing the side plate 502 to extend from the cover 501 under the action of the second spring 503 and abut against the ground behind the base 1. If the impact component continues to move, pushing the support rod 203 further into the slide groove 103, the traction rope 304 can rotate the housing 301, causing the sliding plate 302 to also abut against the ground behind the base 1, thus improving the protective effect in conjunction with the side plate 502.

[0056] In the embodiment one, the shell 301 needs to rotate to the corresponding state with the ground, which requires the support rod 203 to move a certain distance along the sliding groove 103, that is, the impact piece must collide with the support rod 203 to move a certain distance. If the distance is not enough, the shell 301 may not rotate to the corresponding angle with the ground, which cannot form effective support, and there is a certain use limitation.

[0057] Compared with the embodiment one, through the cooperation of the support rod 203, the top rod 205, the cover shell 501 and the side plate 502, when the support rod 203 moves, the cover shell 501 can be pushed out of the base 1, so that the side plate 502 quickly abuts against the ground. At this time, the support rod 203 does not need to move enough distance, that is, the impact piece can form effective support even if the pushing distance of the support rod 203 is small. After the pushing distance is enough, the shell 301 can also rotate to cooperate with the side plate 502 to further improve the protection effect. The overall design is combined with the movement of the support rod 203, and the situation that the shell 301 cannot rotate due to insufficient movement distance of the support rod 203 is avoided, which improves the protection effect of the base 1 and further guarantees the anti-toppling effect. After use, it can also be folded to avoid protrusion, so as not to affect the subsequent folding of the shell 301 and the base 1, and the occupied space is smaller and the applicability is stronger.

[0058] Embodiment three:

[0059] Please refer to Figures 1 to 10 On the basis of the embodiment two, in order to further improve the anti-toppling effect of the base 1, a moving assembly 6 passing through the connecting piece 4 is arranged between two adjacent bases 1, the moving assembly 6 is fixedly connected with the traction rope 304 of one of the bases 1 and fixedly connected with one of the support rods 203 of the other base 1.

[0060] When the traction rope 304 moves, the support rod 203 of the other base 1 can be driven to move synchronously through the moving assembly 6, so that the traction rope 304 and the cover shell 501 of the other base 1 also move synchronously, so as to form that when the impact piece contacts the partition plate 201 of one of the bases 1, the traction rope 304 and the cover shell 501 of the adjacent base 1 are also driven to move synchronously. Correspondingly, the buffering effect of the impact piece is better.

[0061] Further, the connecting piece 4 is designed as a hose, and an opening 401 is formed at the top of the hose. The moving assembly 6 can be operated through the opening 401.

[0062] Please refer to Figure 9 and Figure 10In the embodiment, preferably, the moving assembly 6 comprises a first pull rope 601 fixedly connected with the traction rope 304 and a second pull rope 602 fixedly connected with the support rod 203 on the adjacent base 1, and the adjacent ends of the first pull rope 601 and the second pull rope 602 are relatively fixed by knotting. The first pull rope 601 is perpendicular to the traction rope 304 in the top view, so that the first pull rope 601 is pulled when the traction rope 304 moves.

[0063] In the above structure, the number of the first pull rope 601 and the second pull rope 602 is two and each is staggered, that is, one base 1 corresponds to one first pull rope 601 and one second pull rope 602. Here, the way that the first pull rope 601 and the second pull rope 602 are led out from the opposite sides of the two bases 1 also facilitates the positioning, combination and installation of the two bases 1.

[0064] It should be noted that the embodiment is described by the linkage of the adjacent two bases 1, and the number of the first pull rope 601 and the second pull rope 602 can be increased to meet the synchronous linkage of more bases 1 in actual use.

[0065] It should be further noted that the first pull rope 601 is led out from the left base 1, the second pull rope 602 is led out from the right base 1, and they are relatively fixed by knotting, which provides the function of the connecting piece 4. Therefore, in actual use, the connecting piece 4 can be omitted, and the first pull rope 601 and the second pull rope 602 directly serve as the connecting structure of the adjacent two bases 1.

[0066] In use, the partition plate 201 and the shell 301 can be abutted against the ground on the dumping side of the base 1 to form support, and the top rod 205, the cover 501 and the side plate 502 can make the cover 501 quickly move out to form support when the support rod 203 moves. The working process and effect are the same as those in the second embodiment, which will not be repeated here. The difference is that when the impact piece contacts the cushion layer 202 of one of the bases 1, the support rod 203 moves into the sliding groove 103, at this time, the traction rope 304 of one of the bases 1 is in a released state, the traction rope 304 can pull the first pull rope 601 and the knotted second pull rope 602, the second pull rope 602 can drive the support rod 203 on the adjacent base 1 to move into the sliding groove 103, and then the traction rope 304 on the adjacent base 1 is also in a released state. In this process, the movement of the support rod 203 can drive the cover 501 to move out through the top rod 205 and form support through the side plate 502. In this way, the synchronous movement of the covers 501 and the shells 301 of the adjacent two bases 1 is realized, and the double arrangement can improve the buffering effect of the impact piece.

[0067] In the second embodiment, when multiple bases 1 are used simultaneously, linkage cannot be formed, and if the collision member contacts multiple bases 1 simultaneously, no effect is produced, and if the collision member contacts the cushion 202 of one base 1, no auxiliary supporting force can be provided between other bases 1, so that the linkage protection effect of the device as a whole needs to be improved, and there is a certain use limitation.

[0068] Compared with the second embodiment, through cooperation of the traction rope 304, the supporting rod 203, the first pulling rope 601, and the second pulling rope 602, when the supporting rod 203 and the traction rope 304 of one base 1 move, the supporting rod 203 and the traction rope 304 of other bases 1 can be driven to move synchronously, so that the housings 301 and the cover shells 501 on more bases 1 move synchronously to form support, and the multi-stage linkage can further improve the anti-toppling effect of the bases 1 and the whole. The overall design is combined with the movement of the supporting rod 203, and the first pulling rope 601 and the second pulling rope 602 can replace the connecting structure between adjacent two bases 1, so that the working cost can be further saved and the production benefit can be improved, and more needs in actual use are met.
