Description

Track reinforcing structure of gantry crane Technical Field The utility model belongs to the technical field of portal cranes, and particularly relates to a track reinforcing structure of a portal crane. Background The portal crane is mainly applied to outdoor use, so that the track is reinforced by a track reinforcing structure in order to ensure that the whole portal crane can stably run on the track, the track reinforcing structure in the prior art can be installed by being matched with the track when the track is paved, for example, a portal crane track reinforcing device disclosed in the utility model with the publication number of CN216687139U is required to be fixedly installed at the bottom surface of the track in the use process, and thus, the portal crane track reinforcing device is not suitable for reinforcing the track paved originally in the use process, and therefore, the defect and the defect still exist in the prior art. Disclosure of utility model The utility model aims to provide a track reinforcement structure of a portal crane, which solves the problems in the prior art. In order to solve the problems, the utility model adopts the following technical scheme: The rail reinforcing structure of the portal crane comprises vertically distributed fixed blocks, wherein positioning screws vertically distributed are connected to the fixed blocks in a sliding manner, the top ends of the positioning screws are positioned outside the fixed blocks and are in threaded connection with locking rings, the bottom ends of the positioning screws are coaxially and fixedly connected with limiting blocks, and positioning nails vertically distributed and with sharp ends are coaxially and fixedly connected to the bottom surfaces of the limiting blocks; The top fixedly connected with of one side of fixed block is with fixed block structure as an organic whole consolidates the piece, consolidate the bottom surface of piece and be the slope that inclines upwards, install supplementary clamp on the side of consolidating the piece. Further, the auxiliary pressing piece comprises an extending block which is parallel to the inclined plane of the reinforcing block, the extending block is fixedly connected with the reinforcing block, one side of the extending block far away from the reinforcing block is in threaded connection with a pressing bolt which is perpendicular to the extending block and penetrates through the extending block, the head of the pressing bolt is obliquely arranged upwards, and the screw end of the pressing bolt is sleeved with a connecting sleeve in threaded connection. Further, the auxiliary pressing piece is arranged on the front side and the back side of the reinforcing block. Further, the number of the locking rings on the positioning screw rod is two. Further, the diameter of stopper is greater than the diameter of locating screw rod and locating nail, the locating screw rod is through the vertical first through-hole and the fixed block sliding connection who sets up on the fixed block, set up the second through-hole that sets up with first through-hole coaxial line on the bottom surface of fixed block, the aperture of second through-hole and the diameter looks adaptation of stopper and be greater than the aperture of first through-hole, and the hole height of second through-hole is greater than the vertical distance between the top surface of stopper and the locating nail bottom. By adopting the technical scheme, the utility model has the beneficial effects that: When the fixing device is used, when the fixing device is buckled at the bottom of the track, the inclined surface of the reinforcing block can be abutted against the inclined surface of the bottom of the track, one side of the fixing block, which is close to the reinforcing block, can be abutted against the side edge of the bottom of the track, then a tool hammer or the like can be used for smashing a positioning nail into the ground after the fixing block is pressed manually until the limiting block abuts against the ground, the position of the positioning screw can be fixed, then the locking ring is rotated on the positioning screw until the locking ring abuts against the top surface of the fixing block, the reinforcing block can be pressed against the bottom of the track to reinforce the track, and secondly, when the locking ring is used for pressing the bottom of the track, the auxiliary pressing piece can be used for further pressing the bottom of the track by the reinforcing block to improve the reinforcing effect on the track.
