Description

Technical Field

[0001] This invention relates to the field of highway traffic technology, and in particular to a trigger-type height lifting protection device. Background Technology

[0002] ETC systems are now widely used on highways, and there are numerous gantry structures for installing ETC systems. If a vehicle collision occurs at the ETC gantry location, it may not only cause injury or death to the vehicle occupants, but may also affect the normal operation of the ETC system. Therefore, special guardrail structures are needed for protection.

[0003] Currently, the steel guardrails at this location all use a structure with raised horizontal beams, which is not only complex and expensive, but also has an uneven transition with the standard section of guardrails, affecting the linear landscape effect of the guardrails.

[0004] Therefore, there is an urgent need to provide a new guardrail structure to solve the aforementioned problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a trigger-type height lifting protection device to solve the problems existing in the prior art, which can be smoothly connected and transitioned with standard guardrail sections and is easy to process and install.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a trigger-type height-lifting protective device, including a protective device body, the protective device body including a column, a crossbeam and a beam plate, the beam plate being installed on the top of the column on the side near the driving lane; it also includes a height-lifting mechanism, the crossbeam being installed on the top of the column through the height-lifting mechanism, when the protective device body is hit by a vehicle, the height-lifting mechanism can drive the crossbeam to lift.

[0008] Preferably, a compressible limiting member is provided between the beam and the column, the compressible limiting member being able to deform under pressure upon impact.

[0009] Preferably, the height lifting mechanism includes a sliding sleeve, an elastic component, and a sliding plate. The sliding sleeve is slidably disposed on the top of the column, and the crossbeam is disposed on the top of the sliding sleeve. The elastic component is located inside the sliding sleeve, and its bottom is fixed inside the column. The sliding plate is located above the elastic component, and one end of the sliding plate passes through the compressible limiting member and is fixedly connected to it. The other end of the sliding plate passes through the column and the sliding sleeve, and its end is located outside the column and is limited by the limiting member. The sliding plate has a spring hole for the elastic component to pass through, and the sliding sleeve has a sleeve sliding hole that allows the sliding plate to pass through and enables the sliding sleeve to move up and down relative to the sliding plate.

[0010] In the initial state, the elastic component is in a compressed state. When a vehicle hits the beam, it can deform the compressible limiting member and push the sliding plate toward the side of the column opposite to the driving lane. When the sliding plate moves to the point where the spring hole is directly opposite the elastic component, the elastic component can pass through the spring hole and push the sliding sleeve and the crossbeam upward.

[0011] Preferably, the elastic component includes a plurality of springs arranged sequentially from bottom to top, with the bottom of each spring mounted on a support and a sliding plate disposed above each spring; wherein the support of the lowest spring is fixed to the column, and the supports of the remaining springs are fixed to the sliding sleeve.

[0012] Preferably, the elastic component includes a first spring and a second spring arranged sequentially from bottom to top. The bottom of the first spring is mounted on the column via a first support, and the bottom of the second spring is mounted on the sliding sleeve via a second support. A sliding plate is provided above both the first spring and the second spring, and the sliding plate above the first spring is located below the second support. The sliding sleeve has a first sleeve sliding hole and a second sleeve sliding hole spaced apart from bottom to top. The first sleeve sliding hole and the second sleeve sliding hole are respectively used for the sliding plates above the first spring and the second spring to pass through, and are capable of moving up and down relative to the corresponding sliding plates.

[0013] When a vehicle hits the bottom of the beam, the bottom of the compressible limiting member can be deformed, pushing the sliding plate above the first spring to move toward the side of the column opposite to the driving lane. When the sliding plate moves to the point where the spring hole on it is directly opposite the first spring, the first spring can pass through the spring hole to push the sliding sleeve and the crossbeam upward.

[0014] When a vehicle simultaneously impacts the bottom and top of the beam, the bottom of the compressible limiting member deforms, pushing the sliding plate above the first spring toward the side of the pillar facing away from the roadway. When the sliding plate moves to the point where its spring hole aligns with the first spring, the first spring passes through the spring hole and pushes the sliding sleeve and the crossbeam upward. Simultaneously, the top of the compressible limiting member deforms, pushing the sliding plate above the second spring toward the side of the pillar facing away from the roadway. When the sliding plate moves to the point where its spring hole aligns with the second spring, the second spring passes through the spring hole and pushes the sliding sleeve and the crossbeam upward.

[0015] Preferably, the vertical height of the first sleeve sliding hole is greater than the extension / retraction amount of the first spring, and the vertical height of the second sleeve sliding hole is greater than the extension / retraction amount of the second spring.

[0016] Preferably, the first support is detachably installed on the column by fixing bolts.

[0017] Preferably, a connector is provided at one end of the sliding plate that extends into the compressible limiting member, and the connector is connected to the beam plate; and a limiting block is provided on the side of the connector near the column, the limiting block being used to limit the distance the sliding plate moves toward the column.

[0018] Preferably, the connecting member is a connecting channel steel, which is fixedly connected to the beam plate by bolts; wherein the bolts pass through the beam plate and the connecting channel steel in sequence, and are embedded in the groove of the connecting channel steel for bolting.

[0019] Preferably, the limiting member is an anti-detachment pin, and a fixing pin hole is opened at one end of the sliding plate that protrudes from the column, and the anti-detachment pin passes through the fixing pin hole.

[0020] The present invention achieves the following technical effects compared to the prior art:

[0021] The trigger-type height-lifting protective device of this invention includes a protective device body and a height-lifting mechanism. In the initial state, the overall height of the protective device body matches the height of the standard section guardrail, allowing for a smooth transition and easy processing and installation. It can also form a standard to guide engineering applications and promotion, which is of great significance. When the protective device body is hit by a vehicle, the height-lifting mechanism can drive the crossbeam to lift, increasing the effective height of the overall protective structure. The contact area with the vehicle increases and the interception height increases, which can effectively reduce or even prevent the lateral tilt value generated during the vehicle impact, preventing the vehicle from scraping the ETC gantry column and achieving the purpose of protecting the ETC system.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The purpose of this invention is to provide a trigger-type height lifting protection device to solve the problems existing in the prior art, which can be smoothly connected and transitioned with standard guardrail sections and is easy to process and install.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figures 1-6 As shown, this embodiment provides a trigger-type height-lifting protective device, which can be used for protection in different scenarios. As a preferred embodiment, the trigger-type height-lifting protective device is used for protection on the inner side of the ETC gantry column and is connected to a standard guardrail section. It includes a protective device body, which includes a column 2, a crossbeam 3, and a beam plate 4. The column 2 is anchored in the ground 5, and the beam plate 4 is installed on the top of the column 2 on the side closest to the driving lane. The above structure is similar to the conventional guardrail structure in the art, and will not be described in detail in this embodiment. In this embodiment, the trigger-type height-lifting protective device also includes a height-lifting mechanism. The crossbeam 3 is installed on the top of the column 2 through the height-lifting mechanism. When the protective device body is hit by a vehicle 100, the height-lifting mechanism can drive the crossbeam 3 to lift.

[0035] In its initial state, the overall height of the protective device body in this embodiment matches the height of the standard section guardrail, allowing for a smooth transition and easy processing and installation. It also serves as a standard guide for engineering application and promotion, which is of great significance. When the protective device body is impacted by vehicle 100, the height-lifting mechanism can lift the crossbeam 3, increasing the effective height of the overall protective structure. This increases the contact area with vehicle 100 and the interception height, effectively reducing or even preventing the lateral tilt generated during the impact of vehicle 100, preventing vehicle 100 from scraping against the ETC gantry 1's pillar, thus protecting the ETC system.

[0036] In this embodiment, it should be noted that when the column of the ETC gantry 1 is located in the middle of the road, trigger-type height lifting protection devices are installed on both sides of it; when the column of the ETC gantry 1 is located on the side of the road, trigger-type height lifting protection devices are installed only on its inner side.

[0037] In this embodiment, a compressible limiting member 10 is also provided between the beam plate 4 and the column 2. The compressible limiting member 10 can be deformed by compression when subjected to a collision. The beam plate 4 is bolted to the compressible limiting member 10.

[0038] In this embodiment, as Figures 1-3 As shown, the height lifting mechanism mainly includes a sliding sleeve 12, an elastic component, and a sliding plate 11. The bottom of the sliding sleeve 12 is slidably disposed on the top of the column 2, and the crossbeam 3 is disposed on the top of the sliding sleeve 12. The elastic component is located inside the sliding sleeve 12, and the bottom of the elastic component is fixed inside the column 2. The sliding plate 11 is located above the elastic component, and one end of the sliding plate 11 passes through the compressible limiting member 10 and is fixedly connected to the compressible limiting member 10. The other end of the sliding plate 11 passes through the column. 2 and the sliding sleeve 12, with its end located outside the column 2 and limited by a limiting member to restrict the position of the sliding plate 11; the sliding plate 11 has a spring hole 113 for the elastic component to pass through, the sliding sleeve 12 has a sleeve sliding hole 121, the sleeve sliding hole 121 extends along the length of the sliding sleeve 12, allowing the sliding plate 11 to pass through, and allowing the sliding sleeve 12 to move up and down relative to the sliding plate 11, while the column 2 has a corresponding positioning hole for the sliding plate 11 to pass through.

[0039] In the initial state, the elastic component is in a compressed state, and the spring hole 113 on the sliding plate 11 is located on the side above the elastic component near the beam plate 4. When the vehicle 100 hits the beam plate 4, it can deform the compressible limiting member 10 and push the sliding plate 11 toward the side of the pillar 2 facing away from the driving lane. When the sliding plate 11 moves to the point where the spring hole 113 is directly opposite the elastic component, the elastic component can pass through the spring hole 113 to push the sliding sleeve 12 and the crossbeam 3 upward.

[0040] In this embodiment, the elastic component mainly includes multiple springs arranged sequentially from bottom to top. The bottom of each spring is mounted on a support, and a sliding plate 11 is provided above each spring. The support of the lowest spring is fixed to the column 2, and the supports of the other springs are fixed to the sliding sleeve 12. In this embodiment, multiple springs are provided to achieve multi-level lifting and improve the protective effect.

[0041] In a preferred embodiment, the elastic component includes two springs, namely a first spring 6 and a second spring 8 arranged sequentially from bottom to top. The bottom of the first spring 6 is mounted on a first support 7, which is mounted on the column 2 by a fixing bolt 13. The bottom of the second spring 8 is mounted on the sliding sleeve 12 by a second support 9. A sliding plate 11 is provided above both the first spring 6 and the second spring 8, and the sliding plate 11 above the first spring 6 is located below the second support 9. In the initial state, the sliding sleeve 12 is completely located inside the column 2, and the sliding sleeve 12 can compress the first spring 6 and the second spring 8 respectively through the two sliding plates 11.

[0042] The sliding sleeve 12 is provided with a first sleeve sliding hole and a second sleeve sliding hole spaced apart from bottom to top. The first sleeve sliding hole and the second sleeve sliding hole are respectively used for the sliding plate 11 above the first spring 6 and the second spring 8 to pass through, and can move up and down relative to the corresponding sliding plate 11.

[0043] In this embodiment, the vertical height of the first sleeve sliding hole is greater than the extension and retraction of the first spring 6, and the vertical height of the second sleeve sliding hole is greater than the extension and retraction of the second spring 8, ensuring the overall lifting height.

[0044] In this embodiment, the first support 7 is detachably installed on the column by fixing bolt 13. When the trigger-type height lifting protection device needs to be restored after being hit, the fixing bolt 13 is removed, the first support 7 and the first spring 6 naturally move down, and only the compressible limiting part 10 is replaced. The sliding sleeve 12 returns to its position, the first support 7 is then moved up, the first spring 6 is compressed, and the fixing bolt 13 is inserted to restore it. The operation is convenient.

[0045] In this embodiment, the sliding plate 11 is preferably a sliding steel plate.

[0046] In this embodiment, as Figure 2As shown, a connector is provided at one end of the sliding plate 11 that extends into the compressible limiting member 10. The connector is preferably a connecting channel steel 111, which is bolted to the beam plate 4. Specifically, the bolt passes through the body of the beam plate 4 and the connecting channel steel 111 in sequence and is embedded in the groove of the connecting channel steel 111 for bolting, which facilitates operation. Limiting blocks 112 are provided on both sides of the sliding plate 11. The limiting blocks 112 are located on the side of the connector closer to the column 2 and are used to limit the distance that the sliding plate 11 moves toward the column 2.

[0047] In this embodiment, the limiting member is preferably an anti-detachment pin 14. The sliding plate 11 has a fixing pin hole 114 at one end that protrudes from the column 2. The anti-detachment pin 14 passes through the fixing pin hole 114 to limit the position of the sliding plate 11.

[0048] In this embodiment, the crossbeam 3 is preferably a reinforced crossbeam, and the initial height of the crossbeam 3 does not exceed the height of the beam plate 4. The beam plate 4 is preferably a three-wave beam plate. Furthermore, the crossbeam 3 is provided with a crossbeam bend 301 at one end facing the vehicle direction, and the crossbeam bend 301 is located in front of the ETC gantry 1, which can prevent the crossbeam 3 from inserting into the vehicle body when the vehicle 100 hits the end face of the crossbeam 3.

[0049] like Figure 5 and Figure 6 As shown, the working principle of the trigger-type height lifting protection device in this embodiment is as follows:

[0050] First stage pop-out: When vehicle 100 hits the bottom of beam plate 4, that is, when the bottom of the compressible limiting member 10 deforms, it causes the sliding plate 11 below to slide through the column 2 and the sliding sleeve 12 to slide towards the back side of the column 2 until the limiting block 112 contacts the column 2. At this time, the spring hole 113 on the sliding plate 11 is directly opposite the top position of the first spring 6. The first spring 6 pops out from the spring hole 113 and hits the bottom of the second support 9. The crossbeam 3 is lifted by the first spring 6 and raised to the height of H1.

[0051] In the second stage of ejection: the vehicle 100 impacts the bottom and top of the beam 4. The bottom deformation of the compressible limiting member 10 causes the lower sliding plate 11 to slide, causing the first spring 6 to eject. When the top of the compressible limiting member 10 deforms, the upper sliding plate 11 slides towards the back of the column 2 until the spring hole 113 on the upper sliding plate 11 is aligned with the top of the second spring 8. The second spring 8 ejects from the spring hole 113 and presses against the bottom of the crossbeam 3. The crossbeam 3 is lifted by the second spring 8, raising the height of H2.

[0052] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
