[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses a protective device for road construction.

[0025] Reference Figure 1 , Figure 2The road construction protection device includes a plurality of protection frames 1 for erecting on the road. The bottom of the protection frame 1 is detachably mounted with a plurality of support seats 4 for being placed on the road surface. The number of the support seats 4 can be increased or decreased according to the actual length of the protection frame 1. In this embodiment, two support seats 4 are used as an example.

[0026] like Figure 2 , Figure 3 As shown, two support seats 4 are symmetrically arranged on both sides of the protective frame 1. A limiting groove 40 is provided on the top side wall of the support seat 4 facing the protective frame 1. The width of the limiting groove 40 is adapted to the bottom width of the protective frame 1, and the bottom of the protective frame 1 is inserted into the limiting groove 40 from top to bottom. A plug-in column 41 is also fixedly installed on the bottom wall of the limiting groove 40 facing the protective frame 1. The length of the plug-in column 41 extends along the height direction of the protective frame 1. The bottom of the protective frame 1 is provided with a plug-in hole 10 for the plug-in column 41 to be inserted from bottom to top into the protective frame 1. Through the mutual plug-in cooperation between the plug-in column 41 and the plug-in hole 10, the sliding of the protective frame 1 in the horizontal direction on the support seat 4 can be effectively limited, thereby ensuring the stability of the protective frame 1 installed on the support seat 4.

[0027] like Figure 2 , Figure 3 As shown, the bottom of the support seat 4 is movably provided with a plurality of support blocks 42 whose bottom walls are used to contact the ground. The support blocks 42 are arranged in sequence along the length direction of the support seat 4, and the support blocks 42 are slidably arranged in the support seat 4 along the height direction of the protective frame 1. A plurality of groups of return springs 6 corresponding to the support blocks 42 are arranged in the support seat 4. The return springs 6 are extended and retracted along the sliding direction of the support blocks 42 in the support seat 4. One end of the return spring 6 contacts the inner wall of the support seat 4, and the other end of the return spring 6 is connected and fixed to the respective opposite support blocks 42 and contacts each other. The return spring 6 is used to push the respective support blocks 42 to move in the direction away from the support seat 4 until they contact each other with the road surface. The return spring 6 and the support block 42 can buffer the support seat 4, thereby ensuring the stability of the protective frame 1 when the protective frame 1 is hit.

[0028] like Figure 2 , Figure 3 As shown, a connecting frame 2 is detachably installed on one side of the protective frame 1, and two plug-in slots 11 are provided on the outer side wall of the protective frame 1 facing the connecting frame 2. The cross-section of the plug-in slot 11 along the horizontal direction is roughly T-shaped, and the length of the plug-in slot 11 extends along the height direction of the protective frame 1, and the plug-in slots 11 are symmetrically arranged on both sides of the protective frame 1.

[0029] like Figure 2 , Figure 3As shown, the length of the connecting frame 2 extends in the direction away from the protective frame 1, and the length of the connecting frame 2 is perpendicular to the height of the protective frame 1. The connecting frame 2 includes a first connecting seat 20 and a second connecting seat 21 which are coaxially arranged. A plug-in connector 200 is fixedly installed at one end of the first connecting seat 20, and the shape of the plug-in connector 200 is adapted to the shape of the plug-in slot 11. The first connecting seat 20 is inserted into the plug-in slot 11 from top to bottom through the plug-in connector 200, and the first connecting seat 20 extends from the opening of the plug-in slot 11 to the outside of the protective frame 1. The first connecting seat 20 is fixed to one side of the protective frame 1 by the mutual plug-in connection between the plug-in connector 200 and the plug-in slot 11.

[0030] like Figure 2 , Figure 3 As shown, the second connection seat 21 is slidably sleeved on one end of the first connection seat 20 away from the protective frame 1, and the second connection seat 21 is threadedly connected with a fastener 5. The first connection seat 20 is provided with a plurality of locking holes 22, and the locking holes 22 are arranged in sequence along the sliding direction of the second connection seat 21 outside the first connection seat 20. The locking holes 22 are located on the sliding path of the fastener 5, and the fastener 5 is inserted on the second connection seat 21 along the sliding direction perpendicular to the second connection seat 21, and the fastener 5 is used to be inserted into the relative locking holes 22. After the fastener 5 is unscrewed from the second connection seat 21, the second connection seat 21 can be slid along the length direction of the first connection seat 20, and the position of the second connection seat 21 can be adjusted to achieve the purpose of adjusting the overall length of the connection frame 2. After the length of the connection frame 2 is adjusted, the fastener 5 is re-tightened in the locking hole 22 at the appropriate position, and the second connection seat 21 can be locked on the first connection seat 20.

[0031] like Figure 2 , Figure 3 As shown, a clamping member 3 for clamping and fixing on the elevated guardrail is provided at one end of the second connection seat 21 away from the first connection seat 20. The clamping member 3 includes a first clamp 30 and a second clamp 31 which are arranged opposite to each other. The first clamp 30 and the second clamp 31 are clamped to each other under the action of an external pressure spring. A first clamping groove 32 is formed between the first clamp 30 and the second clamp 31. The inner side wall of the first clamping groove 32 is generally in an arc shape. When the first clamp 30 and the second clamp 31 are separated from each other to overcome the elastic force of the pressure spring, the first clamping groove 32 can be smoothly clamped and fixed on the circular elevated guardrail.

[0032] like Figure 2 , Figure 3As shown, a second clamping groove 33 is formed between the first clamp 30 and the second clamp 31. The second clamping groove 33 and the first clamping groove 32 are respectively located on both sides of the clamping member 3. The inner side wall of the second clamping groove 33 is roughly rectangular. When the first clamp 30 and the second clamp 31 are separated from each other to overcome the elastic force of the pressure spring, the second clamping groove 33 can be smoothly clamped and fixed on the rectangular elevated guardrail.

[0033] like Figure 2 , Figure 3 As shown, the clamping member 3 is rotatably arranged on the second connecting seat 21, and the rotation axis of the clamping member 3 extends along the length direction of the second connecting seat 21. By rotating the clamping member 3, the opening directions of the first clamping groove 32 and the second clamping groove 33 are adjusted, so as to ensure that the clamping member 3 is smoothly and firmly clamped on the elevated guardrail of a specific shape, and then can be adapted to the clamping and fixing of elevated guardrails of different shapes, further increasing the scope of application.

[0034] like Figure 2 , Figure 3 As shown, a threaded column 12 is fixedly provided on one side of the protective frame 1 away from the connecting frame 2, and the threaded column 12 is perpendicular to the protective frame 1. A connecting plate 13 is fixedly provided on the other outer side wall of the protective frame 1 away from the threaded column 12, and the threaded column 12 and the connecting plate 13 are symmetrically arranged on both sides of the protective frame 1. A through hole 14 is penetrated on the connecting plate 13 for the threaded column 12 on the adjacent protective frame 1 to be inserted in the horizontal direction, and a fastening nut 15 is threadedly connected on the threaded column 12, so that each protective frame 1 can be conveniently connected and fixed in sequence through the threaded column 12 and the connecting plate 13, so as to adapt to the construction of roads of different lengths.

[0035] The implementation principle is: the protective frame 1 is fixed to the elevated guardrail through the clamp 3. At this time, the protective frame 1 and the elevated guardrail can be connected and fixed to each other under the traction of the connecting frame 2, so that the protective frame 1 is not prone to the risk of overturning when blown by strong winds, which greatly enhances the fixing effect of the protective frame 1 and improves the overall stability of the protective frame 1. In addition, the protective frame 1 and the support seat 4 are detachably connected. On the one hand, it is convenient for transportation, and on the other hand, it can also replace the worn support seat 4 to ensure the support effect of the support seat 4. This application greatly improves the overall stability of the protective frame 1, so that it can be better applied to the construction needs of elevated roads with strong winds.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
