Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-4, the present utility model provides a technical solution: a guard rail for civil engineering comprising: the base 1 and circular stand 2, circular stand 2 bottom is equipped with base 1, circular stand 2 outer wall rotates and is equipped with changes cover 3, circular stand 2 outer wall is located to change cover 3 below and rotates and be equipped with down changes cover 4, it is equipped with to go up change cover 3 and change cover 4 outer wall one side down and cut arm 5, it is equipped with U-shaped support 6 to cut arm 5 one end, it is equipped with pinch roller 7 to rotate between U-shaped support 6 both ends opening, it has protection fence 10 to press from both sides tightly between the pinch roller 7, it is equipped with fixed plate 8 to go up change cover 3 and change cover 4 outer wall and keep away from U-shaped support 6 one side down, be equipped with fixture block 9 between the fixed plate 8. The protective fence plate 10 is inserted between the pressing wheels 7, the clamping blocks 9 are knocked downwards, the fixing plates 8 rotate towards two sides, due to the scissor-type structure of the scissor arms 5, the pressing wheels 7 can move towards one side of the outer wall of the protective fence plate 10, the pressing wheels 7 clamp and fix the protective fence plate 10, the installation of the protective fence is completed, the whole installation and disassembly process is simple and convenient, and the problem that the protection is fixed due to the fact that the traditional welding fixation is avoided due to the detachable clamping design between the protective fence plate 10 and the upright posts.
The clamping block 9 is in a shape with a narrow center and wide two ends, and two ends of the clamping block 9 are in interference fit with the fixing plate 8. There is the clearance between fixture block 9 central authorities and the fixed plate 8 for go up the cover 3 and rotate the cover 4 and can carry out the rotation of low-angle, then peg graft protection fence board 10 between pinch roller 7, strike fixture block 9 downwards, make fixed plate 8 rotate to both sides.
The outer wall of the pinch roller 7 is made of anti-skid rubber, raised strips 11 are arranged on the outer walls of the two sides of the guard rail plate 10, and the side walls of the raised strips 11 are abutted against the outer wall of the pinch roller 7. The upper rotating sleeve 3, the lower rotating sleeve 4, the shearing arm 5 and the fixing plate 8 form a shearing structure, and when the fixing plate 8 moves to two sides, the pressing wheel 7 moves to one side of the protective fence plate 10. Due to the shear structure of the shear arm 5, the pinch roller 7 can move to one side of the outer wall of the guard rail plate 10, so that the pinch roller 7 clamps and fixes the guard rail plate 10.
The pinch roller 7 is vertical setting, and sand grip 11 one side and pinch roller 7 contact position are equipped with the fillet that increases area of contact, and the fillet diameter is the same with pinch roller 7 external diameter.
The groove is arranged at the contact part between the outer wall of the protective fence board 10 and the pinch roller 7, the contact area between the protective fence board 10 and the pinch roller 7 is increased through the clamping connection between the groove and the pinch roller 7, the friction force is increased, and the stability of the protective fence board 10 is ensured.
Working principle: when the rail guard for civil engineering uses, fix circular stand 2 subaerial according to construction site, when needs installation guard rail board 10, only need upwards or strike fixture block 9 downwards, make fixture block 9 and fixed plate 8 be in the unclamped state, fixture block 9 hangs in fixed plate 8 top this moment, because there is the clearance between fixture block 9 central authorities and the fixed plate 8, make upward swivel 3 and lower swivel 4 can carry out the rotation of small angle, then peg graft guard rail board 10 between pinch roller 7, strike fixture block 9 downwards, make fixed plate 8 rotate to both sides, because the scissors structure of scissor arm 5, pinch roller 7 can be moved to guard rail board 10 outer wall one side, make pinch roller 7 press from both sides tight fixedly to guard rail board 10, accomplish the installation of rail guard, whole installation dismantlement process is simple and convenient, because the detachable joint design between guard rail board 10 and the stand, the problem that traditional welded fastening led to the fact the protection fixed is avoided.
All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
