During the on-site hot construction of the overtaking lane, the regeneration unit is close to the median strip. When the unit heats the asphalt pavement, the surface temperature of the old pavement can reach up to 200°C, and a large amount of high-temperature smoke and heat radiation will be generated, which will have an adverse effect on the green belt and cause huge economic losses. Therefore, certain measures must be taken to protect the green plants in the median strip.

[0004] The guard plates of existing green plant protection devices are mainly temporarily fixed on both sides of the unit using a bracket structure. They must be disassembled, recycled, transported, and stored before and after construction. The process is cumbersome, the disassembly and assembly are complicated and difficult, the space is large, and they cannot be carried with the unit. There are many problems. Utility Model Content

[0057] Figures 1 to 9 An embodiment of a green plant protection device for an on-site heat regeneration unit provided by the utility model is shown. The green plant protection device for an on-site heat regeneration unit includes a first guard plate 11, a second guard plate 12, a support component 13 and a movable connecting member 16. The first guard plate 11 and the second guard plate 12 are hingedly connected, and the first guard plate 11 and the second guard plate 12 can be folded or unfolded, and the second guard plate 12 and the support component 13 are connected by a movable connecting member 16. A first track 14 is provided on one side of the support component 13, and the top end of the first track 14 extends to the end face of the support component 13. The movable connecting member 16 is connected to the side of the second guard plate 12 and is slidably connected to the first track 14. The support component 13 is configured such that when the movable connecting member 16 slides to the top end of the first track 14, the support component 13 can rotate relative to the second guard plate 12.

[0058] When the second guard plate 12 and the support component 13 slide relative to each other, the support component 13 is close to the side surface of the second guard plate 12 and is parallel or approximately parallel. When the movable connecting member 16 slides to the top along the first track 14, the second guard plate 12 can rotate to match the end surface of the support component 13. At this time, the second guard plate 12 and the support component 13 form an angle.

[0059] When using, Figure 1 As shown, the first guard plate 11 and the second guard plate 12 are unfolded and erected, and the first guard plate 11 can be flipped to the top of the second guard plate 12 to increase the overall height of the green plant protection device, which can block the high-temperature smoke and heat radiation of the asphalt pavement during the on-site hot regeneration construction and protect the green plants; the second guard plate 12 and the support component 13 are relatively rotated to form an angle, and the support component 13 can support the second guard plate 12. A connecting seat 131 can be provided at one end of the support component 13 away from the second guard plate 12, and the connecting seat 131 can be fixedly connected to the longitudinal beam of the on-site hot regeneration unit or other positions.

[0060] When recycling, Figure 2 As described above, the first guard plate 11 and the second guard plate 12 are folded up, the support component 13 is rotated to fit the side of the second guard plate 12, and the second guard plate 12 is slid along the first track 14 and stored on one side of the support component 13. This can reduce the overall volume of the green plant protection device, making it easy to recycle and transport, and convenient for random group carrying.

[0061] The first guard plate 11, the second guard plate 12 and the supporting component 13 can be directly unfolded or folded without installing or disassembling the components. The operation is simple and convenient, which can save labor and improve construction efficiency.

[0062] The first guard plate 11 and the second guard plate 12 are made of refractory materials and can withstand the high temperature environment during the on-site hot regeneration construction process to ensure the quality of use.

[0063] In some embodiments, Figure 3 As shown, the first guard plate 11 and / or the second guard plate 12 include an internal refractory material 101 and a metal shell 102 covering the outside of the refractory material 101. The refractory material 101 can be a benzene board, which can block heat, and is light and easy to carry. The metal shell 102 can be an iron plate, a steel plate, etc. The metal shell 102 covers the entire surface of the refractory material 101, and can fully protect the refractory material 101.

[0064] In some embodiments, Figure 6 and Figure 7 As shown, the first guard plate 11 is configured to be able to rotate toward the side of the second guard plate 12 away from the support component 13, so that the first guard plate 11 and the support component 13 can be prevented from interfering when folded and stored. Specifically, the first guard plate 11 and the second guard plate 12 are connected by a hinge 103, and the hinge 103 is connected to the side of the first guard plate 11 and the second guard plate 12 away from the support component 13.

[0065] In some embodiments, Figure 1 , Figure 2 and Figure 4As shown, a second track 15 is provided on the side of the second guard plate 12, and a movable connecting member 16 is slidably connected to the second track 15. In detail, when the second guard plate 12 is parallel to the supporting member 13, the first track 14 and the second track 15 are also parallel to each other and correspond in position. When the first guard plate 11 and the second guard plate 12 are unfolded and erected, the second track 15 extends in the height direction, and the supporting member 13 can be supported at different height positions of the second guard plate 12 along the second track 15.

[0066] In some embodiments, Figure 2 As shown, a limiting member 151 is provided on the second track 15, and the limiting member 151 is used to limit the movable connecting member 16. Specifically, when the second guard plate 12 slides relative to the supporting member 13, the limiting member 151 can push the movable connecting member 16, so that the movable connecting member 16 can slide along the first track 14 and can slide to the top of the first track 14.

[0067] Furthermore, the position-limiting member 151 is configured to be fixed at different positions of the second rail 15 , so that the height position of the supporting component 13 supported on the second guard plate 12 can be adjusted.

[0068] Specifically, the limiting member 151 may be a bolt, a pin, a block, etc., which is detachably mounted on the second rail 15. The second rail 15 may be provided with a plurality of holes for mounting the limiting member 151 along the length direction.

[0069] In some embodiments, Figure 3 and Figure 4 As shown, the movable connecting member 16 includes a connecting rod 161 and two movable blocks 162. The two movable blocks 162 are respectively arranged at opposite ends of the connecting rod 161, and the two movable blocks 162 are respectively slidably engaged in the first track 14 and the second track 15.

[0070] In detail, the cross-sections of the first track 14 and the second track 15 are C-shaped structures, the two movable blocks 162 are slidably restricted in the C-shaped structure, and the connecting rod 161 extends from the opening of the C-shaped structure. The two movable blocks 162 are enlarged ends of the connecting rod 161 and cannot be separated from the opening of the C-shaped structure, thereby connecting the second guard plate 12 and the support member 13. The limiting member 151 can limit the movable block 162 in the second track 15.

[0071] Furthermore, if Figure 5As shown, the top of the first track 14 is provided with a track opening 141, and the connecting rod 161 is configured to be able to rotate into the track opening 141. The movable block 162 can be a sphere or a cylinder, and can rotate in the first track 14 and the second track 15. When the movable connecting member 16 slides to the top of the first track 14, the connecting rod 161 can rotate into the track opening 141, thereby realizing the relative rotation of the second guard plate 12 and the supporting component 13.

[0072] In some embodiments, Figure 1 and Fig. 9 As shown, a first rotating support 17 is provided between the first guard plate 11 and the second guard plate 12, one of the first guard plate 11 and the second guard plate 12 is rotatably connected to the first rotating support 17, and the other of the first rotating support 17 is detachably connected to the first rotating support 17. When the first guard plate 11 and the second guard plate 12 are in the unfolded state, the first rotating support 17 can connect the first guard plate 11 and the second guard plate 12 and limit the position. The first rotating support 17 can be connected to the side of the first guard plate 11 and the second guard plate 12 close to the support component 13.

[0073] In one example, one end of the first rotating support 17 is connected to the second guard plate 12 through a fixing pin 19, and the first rotating support 17 can rotate around the fixing pin 19. The first guard plate 11 is provided with a mounting hole 110 for mounting a fastener 20, and the end of the first rotating support 17 away from the fixing pin 19 can be fixedly connected to the first guard plate 11 through the fastener 20. The fastener 20 can be a pin, a bolt, etc. After the fastener 20 is removed, the first guard plate 11 and the second guard plate 12 are freed from the limit and can be folded up, and the first rotating support 17 can be stored on the side of the second guard plate 12 by rotating it.

[0074] In some embodiments, Figure 1 and Figure 4 As shown, a second rotating support member 18 is provided between the second guard plate 12 and the supporting member 13, and the number of the second rotating support members 18 can be one or more. One of the second guard plate 12 and the supporting member 13 is rotatably connected to the second rotating support member 18, and the other of them is detachably connected to the second rotating support member 18. When the supporting member 13 and the second guard plate 12 form an angle, the second rotating support member 18 is connected between the supporting member 13 and the second guard plate 12, and can support the second guard plate 12.

[0075] In one example, one end of the second rotating support member 18 is hinged to the support member 13 through a rotating shaft, and the other end forms a hook (not shown in the figure). A hanging hole 21 is provided on one side of the connecting support member 13 of the second guard plate 12. Rotating the second rotating support member 18 can make the hook hang in the hanging hole 21 to achieve connection and support with the second guard plate 12. The second rotating support member 18 forms a stable triangular support between the end of the support member 13 and the second guard plate 12.

[0076] In some embodiments, a plurality of support components 13 are provided, and the first tracks 14 on the plurality of support components 13 are parallel to each other and are respectively connected to the second guard plate 12 through different movable connecting members 16 . Increasing the number of support components 13 can improve the support stability of the second guard plate 12 .

[0077] like Figure 1 In a specific embodiment shown, two support members 13 are provided and spaced apart, the first tracks 14 on the two support members 13 are parallel, and two second tracks 15 are correspondingly provided on the side of the second guard plate 12. The stoppers 151 on the two second tracks 15 are at the same height, and the two movable connecting members 16 can slide to the top of the corresponding second tracks 15 at the same time, so as to ensure that the second guard plate 12 can rotate relative to the support member 13.
