The height limit equipment will set corresponding height limit warning signs according to construction needs to mark the height limit. The required marked heights for different municipal projects are different. Usually, the height limit warning signs are installed on the height limit equipment through bolts. When replacing, professional personnel need to use corresponding auxiliary tools for disassembly, and then continuously adjust the torque of the bolts for installation. Too tight or too loose will affect the installation quality. However, the existing safety height limit equipment for municipal engineering does not have components for conveniently replacing the height limit warning signs.

[0004] The present utility model is realized as follows. A safety height limit device for municipal engineering includes two support frames and a bracket. The bottom of the bracket is fixedly connected to the top of the support frame. A height limit rod is movably connected to one side of the two support frames facing each other. An installation shell is fixedly connected to the front side of the height limit rod.

[0006] Preferably, two extrusion rotating blocks are movably connected to one side of the inner cavity of the device shell close to the limiting block through a rotating shaft. The surface of the extrusion rotating block contacts the surface of the control extrusion plate.

Specific embodiments

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and detailed as follows in conjunction with the accompanying drawings.

[0020] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 4 shown, a safety height limit device for municipal engineering provided by an embodiment of the present invention includes two support frames 1 and brackets 2. The bottom of the bracket 2 is fixedly connected to the top of the support frame 1. A height limit rod 3 is movably connected to one side of the two support frames 1 facing each other. An installation shell 4 is fixedly connected to the front side of the height limit rod 3. A device shell 5 that cooperates with the installation shell 4 is movably connected to the inner cavity of the installation shell 4. A height limit warning sign 6 is fixedly connected to the front side of the device shell 5. Two extrusion control plates 7 are movably connected to the inner cavity of the device shell 5. One side of the two extrusion control plates 7 facing away from each other penetrates through the device shell 5 and extends to the outside of the inner cavity of the device shell 5. A limiting device 8 is arranged inside the device shell 5.

[0022] Referring to Figure 4 , the limiting device 8 includes two limiting blocks 801. One side of the two limiting blocks 801 facing away from each other penetrates through the device shell 5 and extends to the outside of the inner cavity of the device shell 5. Outer shells 802 are fixedly connected to one side of the two limiting blocks 801 facing away from each other. Inner shells 803 are movably connected to the inner cavities of the outer shells 802. One side of the two inner shells 803 facing away from each other is fixedly connected to the inner cavity of the device shell 5. Springs 804 are fixedly connected to one side of the two limiting blocks 801 facing away from each other. One side of the two springs 804 facing away from each other is fixedly connected to the inner cavity of the device shell 5.

[0023] Adopting the above scheme: By arranging the limiting device 8, when the height limit warning sign 6 moves to a suitable position, the limiting device 8 has a limiting effect on the position of the height limit warning sign 6.

[0024] Referring to Figure 4, on one side of the inner cavity of the device housing 5 close to the limiting block 801, two extrusion rotating blocks 9 are movably connected by a rotating shaft, and the surface of the extrusion rotating block 9 contacts the surface of the control extrusion plate 7.

[0025] With the above solution: by setting the extrusion rotating block 9, when the extrusion control plate 7 moves, it will drive the extrusion rotating block 9 to rotate through the rotating shaft. When the extrusion rotating block 9 rotates, it can drive the extrusion hole 10 to rotate along the surface of the extrusion rod 11.

[0026] Reference Figure 4 , an extrusion hole 10 is formed on the surface of the extrusion rotating block 9. A front side of the limiting block 801 is fixedly connected with an extrusion rod 11 that is used in cooperation with the extrusion hole 10. The front side of the extrusion rod 11 penetrates through the extrusion hole 10 and extends to the outside of the inner cavity of the extrusion hole 10. The surface of the extrusion rod 11 contacts the inner cavity of the extrusion hole 10.

[0027] With the above solution: by setting the extrusion hole 10 and the extrusion rod 11, the extrusion hole 10 can generate an extrusion force on the extrusion rod 11, and the extrusion rod 11 subjected to the extrusion force can drive the limiting block 801 to move.

[0028] Reference Figure 4 , both the top and bottom of the device housing 5 are fixedly connected with moving rods 12 that are used in cooperation with the extrusion control plate 7. Opposite sides of the two moving rods 12 penetrate through the extrusion control plate 7 and extend to the outside of the extrusion control plate 7.

[0029] With the above solution: by setting the moving rods 12, pressing the extrusion control plate 7 will drive the extrusion control plate 7 to move along the surface of the moving rods 12. The setting of the moving rods 12 has a limiting effect on the moving position of the extrusion control plate 7.

[0030] Reference Figure 3 , limiting grooves 13 that are used in cooperation with the limiting block 801 are formed on both the left and right sides of the inner cavity of the installation housing 4. The surface of the limiting block 801 contacts the inner cavity of the limiting groove 13.

[0031] With the above solution: by setting the limiting grooves 13, when the device housing 5 moves into the inner cavity of the installation housing 4 and the extrusion control plate 7 is released, the restoring force generated by the spring 804 restoring its shape will drive the limiting block 801 to be clamped in the inner cavity of the limiting groove 13. The cooperation between the limiting block 801 and the limiting groove 13 has a limiting effect on the position of the device housing 5.

[0032] Reference Figure 3 , T-shaped insertion blocks 14 are fixedly connected to both the left and right sides of the device housing 5. A T-shaped insertion groove 15 that is used in cooperation with the T-shaped insertion block 14 is formed on the top of the device housing 5. The surface of the T-shaped insertion block 14 contacts the inner cavity of the T-shaped insertion groove 15.

[0033] Adopting the above solution: By setting the T-shaped insertion block 14 and the T-shaped insertion groove 15, when the device housing 5 moves, it will drive the T-shaped insertion block 14 to move into the inner cavity of the T-shaped insertion groove 15. The combined use of the T-shaped insertion block 14 and the T-shaped insertion groove 15 has a limiting effect on the moving position of the device housing 5.

[0034] The working principle of the present utility model:

[0035] During use, when the safety height limit device for municipal engineering needs to conveniently replace the height limit warning sign 6, first, the operator removes the warning sign to be replaced, and then pushes the extrusion control plates 7 towards the opposite sides of each other, driving the extrusion control plates 7 to move along the surface of the moving rod 12. When the extrusion control plates 7 move, they will generate an extrusion force on the extrusion rotating block 9. The extrusion rotating block 9 subjected to the extrusion force will drive the extrusion hole 10 to rotate along the surface of the extrusion rod 11. The extrusion hole 10 will generate an extrusion force on the extrusion rod 11. The two extrusion rods 11 subjected to the extrusion force will move towards each other. When the extrusion rods 11 move, they will drive the two limit blocks 801 to move towards each other. When the limit blocks 801 move, they will drive the outer shell 802 to move along the surface of the inner shell 803. When the force generated by the movement of the limit blocks 801 causes the spring 804 to undergo elastic deformation, when the limit blocks 801 completely move into the inner cavity of the device housing 5, the T-shaped insertion block 14 is moved into the inner cavity of the T-shaped insertion groove 15, and at the same time, the device housing 5 is completely moved into the inner cavity of the mounting housing 4. Then, the two extrusion control plates 7 are released. The restoring force generated by the spring 804 restoring its shape will drive the limit blocks 801 to be clamped in the inner cavity of the limit groove 13. The combined use of the limit blocks 801 and the limit groove 13 has a limiting effect on the positions of the device housing 5 and the height limit warning sign 6. At this time, the safety height limit device for municipal engineering completes the convenient replacement of the height limit warning sign 6.

[0036] In summary: For this safety height limit device for municipal engineering, through the combined use of the limiting device 8, the limit blocks 801, the outer shell 802, the inner shell 803 and the spring 804, the height limit device for municipal engineering is mainly used to control and manage traffic flow, ensure traffic safety, and prevent large vehicles from entering certain specific areas. The height limit device will set corresponding height limit warning signs according to construction needs to mark the height of the height limit. The heights required to be marked for different municipal engineering are different. Usually, the height limit warning signs are installed on the height limit device through bolts. When replacing, professional personnel need to use corresponding auxiliary tools for disassembly, and then continuously adjust the torque of the bolts for installation. Being too tight or too loose will affect the installation quality. However, the existing safety height limit devices for municipal engineering do not have components for conveniently replacing the height limit warning signs.
