Concrete vibrating rod inserting and pulling speed regulating device for building construction

Abstract

The invention relates to a concrete vibrating rod inserting and pulling speed regulating device for building construction, and discloses a speed regulating device. The speed regulating device regulates the inserting and pulling speed of a vibrating rod through a ratchet wheel and pawl structure, can form angle guide when the vibrating rod is inserted, and is characterized in that a supporting plate is of an annular plate-shaped structure, one ends of multiple connecting plates are connected with the bottom of the supporting plate at equal angles, the other ends of the connecting plates extenddownwards, bottom supporting feet are arranged at the other ends of the connecting plates, reinforcing ribs are arranged between the bottom supporting feet and the connecting plates, a balance weightring is located below the supporting plate and close to the other ends of the connecting plates, and at least three fixing frames are arranged on the supporting plate at equal angles; and the fixing frames are composed of two fixing plates, one ends of the fixing plates are fixedly connected with the top of the supporting plate, the other ends of the fixing plates extend obliquely upwards close tothe center line of the supporting plate, guide rollers are arranged on the fixing frames through roller shafts, a plurality of anti-skid strips are arranged on the guide rollers, and ratchet wheels are arranged at the positions, close to a supporting frame, of the roller shafts.

[0002] At present, in the process of cable layout, some cables need to be suspended and fixed from a high place. The existing suspension is currently in the process of building construction. Generally, during pouring, manual hand-held vibrating rods are used to insert them into the concrete for vibrating work. When using the vibrating rods, it is necessary to follow the operation method of quick insertion and slow removal. The quick insertion is to prevent the surface layer from being vibrated. The concrete is vibrated first, and delamination and segregation occur with the lower concrete, and the slow pulling is to make the concrete have time to fill the cavity formed when the vibrator is pulled out, and because the quick insertion and slow removal are all done manually, the Workers have high requirements for operating experience, and it is difficult to accurately control the speed of slow pulling when manual slow pulling is performed, resulting in operational errors and resulting in holes in the concrete
