Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a road and bridge construction protection device. Background Art

[0002] Road and bridge construction refers to the survey, design, construction, maintenance, and management of highways and bridges. Road and bridge projects can be divided into roadbed, pavement, bridges, culverts, tunnels, drainage, protection, greening, traffic engineering, electromechanical and other projects according to their structures. When roads and bridges are under construction, warning signs and road cones will be used in combination for protection.

[0003] However, when the existing warning signs are in use, they are placed on the ground through a bracket. Since the bracket is composed of four columns, the supporting strength is poor. When encountering strong winds or passing vehicles, they are easily blown down or tilted, which easily affects the warning effect. Therefore, we propose a road and bridge construction protection device to solve the above problem. Utility Model Content

[0007] Preferably, the cross section of the storage frame is set to be U-shaped, and two groups of storage frames are symmetrically arranged on the surface of the reinforcing cross bar.

[0011] Preferably, the limiting mechanism includes a fixing frame, which is fixedly connected to the top of the storage frame, and a second stud is threadedly inserted into the top of the fixing frame, and a second clamping block is abutted at the bottom of the second stud, and a reset spring is welded between the inner wall of the fixing frame and the top of the second clamping block, so that the second clamping block can be easily pushed by the second stud, and the reset spring can reset the second clamping block.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4 A road and bridge construction protection device includes a construction warning sign 1. A support frame 2 is installed on the surface of the construction warning sign 1, and a reinforcing cross bar 3 is fixed at the bottom of the support frame 2. A storage frame 4 is fixed on the surface of the reinforcing cross bar 3, and a folding mechanism 5 is hinged in the storage frame 4. The storage frame 4 can facilitate the storage of the limit folding mechanism 5. The outer end of the folding mechanism 5 is fixedly connected to a support mechanism 6, and the upper part of the storage frame 4 is fixedly connected to a limit mechanism 7.

[0026] Further, see Figure 1 and Figure 3 It can be seen that the cross section of the storage frame 4 is set to be U-shaped, and two groups of storage frames 4 are symmetrically arranged on the surface of the reinforcing cross bar 3. By setting the cross section of the storage frame 4 to be U-shaped, the folding mechanism 5 can be easily rotated as a whole inside it.

[0027] Further, see Figure 3 and Figure 4 It can be known that the folding mechanism 5 includes a hinge shaft 51, and a hinge rod 52 is hinged inside the storage frame 4 through the hinge shaft 51. A first clamping block 53 is fixedly connected above the hinge shaft 51. The hinge shaft 51 can conveniently drive the hinge rod 52 to rotate inside the storage frame 4.

[0028] Further, see Figure 3 and Figure 4 It can be known that the support mechanism 6 includes a fixed block 61, the outer end of the hinged rod 52 is fixedly connected to the fixed block 61, and the internal thread of the fixed block 61 is inserted with a first stud 62, and the lower part of the first stud 62 is fixedly connected to a support plate 63. By rotating the first stud 62, it can be moved in the fixed block 61, which facilitates the function of pushing the support plate 63.

[0029] Further, see Figure 3 and Figure 4 It can be known that the cross-section of the support plate 63 is set to be circular, and an anti-skid rubber pad 64 is glued to the bottom of the support plate 63, and the surface of the anti-skid rubber pad 64 is provided with anti-skid grooves. The anti-skid grooves on the surface of the anti-skid rubber pad 64 can increase the friction between the support plate 63 and the ground.

[0030] Further, see Figure 1 and Figure 3 It can be known that the limiting mechanism 7 includes a fixed frame 71, the upper part of the storage frame 4 is fixedly connected with the fixed frame 71, and the top of the fixed frame 71 is threadedly inserted with a second stud 72, and the lower part of the second stud 72 abuts against a second clamping block 73. By rotating the second stud 72, the second stud 72 can push the second clamping block 73 to move, and a reset spring 74 is welded between the inner wall of the fixed frame 71 and the upper part of the second clamping block 73. The elastic force of the reset spring 74 itself can easily reset the second clamping block 73 and keep it away from the first clamping block 53.

[0031] Further, see Figure 1 and Figure 3 It can be seen that the cross-section of the second clamping block 73 is set to be rectangular, and a rectangular groove adapted to the first clamping block 53 is opened below the second clamping block 73. The second clamping block 73 is sleeved on the surface of the first clamping block 53, which can facilitate the function of limiting and fixing the first clamping block 53.

[0032] Working principle: When the utility model is in use, when the construction warning sign 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 The second stud 72 can be unfolded and rotated to make the second stud 72 away from the surface of the second block 73. At this time, the elastic force of the return spring 74 can make the second block 73 away from the surface of the first block 53. When the hinged rod 52 is moved, the hinged rod 52 can drive the hinge shaft 51 and the first block 53 to rotate in the storage frame 4. When the hinged rod 52 drives the fixing block 61 to unfold, the second stud 72 can be rotated to make the second stud 72 push the second block 73 so that the second block 73 is engaged with the surface of the first block 53, so as to limit the hinged rod 52. At this time, by rotating the first stud 62, the support plate 63 can drive the anti-skid rubber pad 64 to contact the ground, so as to increase the overall stability of the support frame 2.

[0033] The above is the entire working principle of the utility model.

[0034] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0035] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
