DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0029] like Figure 1 and Figure 2As shown, the present invention provides a road guardrail installation structure for municipal construction, including a fixed base plate 1 and a guardrail 2. The fixed base plate 1 is set to stably fix the device on the ground of the municipal road. Both ends of the upper side of the fixed base plate 1 are fixedly connected with support columns 3, and the support columns 3 are hollow. Both ends of the lower side of the guardrail 2 are fixedly connected with clamping tubes 4. The guardrail 2 is fixedly connected with a first plug-in column 5 in the clamping tube 4. The first plug-in column 5 is coaxially arranged with the clamping tube 4. Both ends of the upper side of the fixed base plate 1 are provided with clamping grooves 6. The fixed base plate 1 is fixedly connected with a second plug-in column 7 in the clamping groove 6. The second plug-in column 7 is coaxially arranged with the first plug-in column 5. A first spring 8 is arranged between the clamping tube 4 and the first plug-in column 5. The upper end of the first spring 8 is sleeved on the outside of the first plug-in column 5, and the lower end of the spring is sleeved on the second plug-in column 7, the lower end of the spring is inserted into the card slot 6, the card tube 4 and the first plug column 5 are provided to stably fix the upper end of the first spring 8 on the lower side of the guardrail 2, and the card slot 6 and the second plug column 7 are provided to stably fix the lower end of the first spring 8 on the fixed base plate 1. The first spring 8 has a dual function. One is to connect the guardrail 2 with the fixed base plate 1, and the guardrail 2 is in a vertical state as much as possible due to the elastic force of the first spring 8 itself. The second is that when the guardrail 2 is hit, the first spring 8 converts the rigid connection between the guardrail 2 and the fixed base plate 1 into an elastic connection, and the guardrail 2 can rotate. Then, when one of the guardrails 2 falls, it will not affect the other guardrails 2 next to it. After the force disappears, the guardrail 2 returns to a vertical state due to the force of the first spring 8. The device can make the guardrail 2 in a stable vertical state under normal circumstances through the force of the first spring 8. When it is hit, the guardrail 2 rotates and tilts without affecting the guardrail 2 next to it, preventing a large area of ​​the guardrail 2 from being damaged.

[0030] like Figure 1 and Figure 3 As shown, an auxiliary component 9 is provided in the support column 3, and the auxiliary component 9 includes a guide rod 91 and a connecting rope 92. One end of the guide rod 91 is fixedly connected to the fixed bottom plate 1, and the upper end of the guide rod 91 is fixedly connected to the upper end of the support column 3. The guide rod 91 and the support column 3 are coaxially arranged, and the guide rod 91 is in the support column 3. The guide rod 91 is sleeved with a second spring 93, and the upper end of the second spring 93 is fixedly connected to the upper end of the support column 3. Figure 4As shown, a slider 94 is fixedly connected to the lower end of the second spring 93, and the guide rod 91 passes through the slider 94. The slider 94 is slidably connected to the guide rod 91, and one end of the connecting rope 92 is fixedly connected to the slider 94. A through hole 95 is opened on the upper side of the support column 3, and the connecting rope 92 passes through the through hole 95. The other end of the connecting rope 92 is fixedly connected to the guardrail 2. The auxiliary component 9 cooperates with the first spring 8 for buffering. The guide rod 91 provides a good guiding effect for the second spring 93. The connecting rope 92 transmits the force of the inclined guardrail 2 to the slider 94. The slider 94 transmits the force to the second spring 93 when sliding on the guide rod 91. The second spring 93 provides good elastic force after compression, and then has a pulling effect on the inclined guardrail 2, so as to prevent the guardrail 2 from colliding with the ground due to excessive rotation angle and causing damage.

[0031] like Figure 5 As shown, a guide assembly 10 is provided near the through hole 95 of the support column 3, and the guide assembly 10 includes a first support member 101 and a second support member 102, and the first support member 101 and the second support member 102 are respectively fixed on both sides of the through hole 95, the first support member 101 is sleeved with a first wire wheel 103, and the first wire wheel 103 is rotatably connected to the first support member 101, and the second support member 102 is sleeved with a second wire wheel 104, and the second wire wheel 104 is rotatably connected to the second support member 102, and the connecting rope 92 is located between the first wire wheel 103 and the second wire wheel 104. The set guide assembly 10 provides good guidance for the movement of the connecting rope 92. When the guardrail 2 is tilted, the set first wire wheel 103 and the second wire wheel 104 can stably clamp the connecting rope 92 therebetween while rotating, so that the tilting of the guardrail 2 is smoother and the excessive friction of the connecting rope 92 is prevented from causing breakage.

[0032] like Figure 2 As shown, a first anti-slip washer 11 is fixedly connected to the circumferential side of the inner wall of the clamping tube 4, and a second anti-slip washer 12 is fixedly connected to the circumferential side of the inner wall of the clamping groove 6. The first anti-slip washer 11 and the second anti-slip washer 12 are both rubber washers with good elasticity and anti-slip properties. The first anti-slip washer 11 and the second anti-slip washer 12 provide good friction for the upper and lower ends of the first spring 8, thereby improving the stability and safety of the first spring 8.

[0033] The implementation principle of this embodiment is as follows: when the device is used, the device is first fixed on the ground of the municipal road through the fixed base plate 1. When one of the guardrails 2 is hit, the guardrail 2 rotates and drives the first spring 8 at that position to bend, and the guardrail 2 topples over without affecting the guardrails 2 next to it. At the same time, the guardrail 2 pulls the connecting rope 92, and the connecting rope 92 moves between the first guide wheel 103 and the second guide wheel 104. The rotation of the first guide wheel 103 and the second guide wheel 104 plays a good guiding role for the connecting rope 92. The connecting rope 92 drives the slider 94 to move upward along the guide rod 91. At this time, the second spring 93 is in a compressed state, and the connecting rope 92 plays a pulling role for the guardrail 2.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
