In order to achieve the above object, the utility model provides a following technical scheme: a device for preventing prefabricated arch box from toppling over comprises
The support body, the support body center is equipped with the steel chain, the support body inboard is equipped with the steel sheet, be equipped with the inclinometer on the steel sheet, the steel sheet avris is equipped with the channel-section steel, the steel chain bottom is equipped with damping spring shock absorber, damping spring shock absorber bottom is equipped with the gyro wheel.
Preferably, the support body is formed by welding I-steel, and the inclinometer is fixedly installed on the upper portion of the support body.
Preferably, the bottom of the inclined strut at two sides of the frame body is connected with the damping spring shock absorber through two high-strength bolts, and meanwhile, the lower part of the damping spring shock absorber is provided with the simple roller.
Preferably, a reinforcing protection structure is arranged between the frame body and the arch box, and the reinforcing protection structure is formed by welding two steel plates which are parallel to each other on the inner side of the frame body.
Preferably, an integral stability reinforcing structure is arranged between the two frame bodies, the integral stability reinforcing structure is formed by respectively abutting two channel steels at the upper position and the lower position on the vertical I-shaped steels at the two sides of the frame body, and the channel steels are connected with the I-shaped steels through bolts.
Prevent that prefabricated case that encircles from taking place the device of empting in the transportation, vertically install two support bodies respectively at the case of encircleing, encircle the case and when dragging and remove, survey the balanced state who encircles the case at any time through the inclinometer, in time stop dragging when the inclination number of degrees is too big, adjust the balance that encircles the case, avoid crooked case that encircles to be continued to drag and move ahead and lead to empting. When the arch box is too large in inclination amount and people do not timely find that the arch box is inclined, the damping spring shock absorbers at the bottoms of the inclined struts on the two sides of the frame body play a role, so that potential energy impact caused by inclination of the arch box is relieved, and the frame body and the structure of the arch box are protected.
Can set up between hunch case and the support body and strengthen protective structure, strengthen protective structure for at the inboard welding of support body two steel sheets that are parallel to each other to increase and the area of contact who encircles the case, alleviate the damage of energy impact to hunch case concrete structure brought in the twinkling of an eye in the slope.
Can set up between two support bodies and strengthen overall stability structure, strengthen overall stability structure for respectively on the vertical I-steel of support body both sides the position from top to bottom near two channel-section steels of installation, the channel-section steel passes through the bolt and is connected with the I-steel.
The utility model discloses a technological effect and advantage: through class triangle bracing structure support body, the steel chain, the inclinometer, damping spring shock absorber, make the device optimize the structure of self, during the use, the user is fixed in the support body on encircleing the case, prevent the vertical removal of support body through the fastening steel chain, survey the running balance state who encircles the case through the inclinometer, alleviate the potential energy impact because of empting and bring through damping spring shock absorber, above effect, the practicality and the reliability of device have been strengthened, be favorable to the device to use widely under the simple and crude environment of construction condition.
