Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a reinforcing structure of a road and a bridge comprises a limiting column 2, a gear 3 and a shell 12, wherein the gear 3 is arranged inside the shell 12, racks 7 are arranged inside the shell 12 at two sides of the gear 3, gear blocks 6 are uniformly arranged on the inner sides of the racks 7, and one side of the tooth block 6 far away from the rack 7 is meshed with the outer side of the gear 3, the top end of the shell 12 is provided with a through hole 14, the bottom end of the shell 12 is provided with a limit block 17, and the second pinhole 16 has all evenly been seted up all around to the inside bottom of stopper 17, first pinhole 5 has evenly been seted up all around to the inside of gear 3, and the inside of gear 3 is provided with spacing post 2, and hexagonal bolt head 13 is installed on the top of spacing post 2, and the outside of hexagonal bolt head 13 is just all installed first spacer pin 4 to first pinhole 5 position department, and the outside bottom of spacing post 2 is just all installed second spacer pin 18 to second pinhole 16 position department.

In this implementation: the rack 7 keeps away from the one end of gear 3 and all installs arm-tie 1, and the locating hole 8 has all evenly been seted up in arm-tie 1's outside, use arm-tie 1 and locating hole 8 can make things convenient for the device to be connected with the bridge road surface better, two sets of installation pieces 9 are all installed to the both sides of casing 12, stability when having increased the device installation, the bolt 11 is installed on the top of hexagonal bolt head 13, use the bolt 11 can be comparatively conveniently with spacing post 2 take out and install, the use degree of difficulty of device has been reduced, the in-service use value of device has been improved, anti-skidding groove 10 has evenly been seted up on the top of casing 12, the security when having increased the device use, reinforcing plate 15 has all been installed between the both ends of second pinhole 16 and the bottom of casing 12, the intensity of the device is strengthened this thing, the life of.

The working principle is as follows: when the device is used, firstly, the shell 12 is placed at the upper part of a bridge crack, so that the pull plates 1 are respectively lapped at two ends of the crack, then the fixing bolt is driven into the road surface of the bridge through the positioning hole 8, the preparation work of the device is completed, the hexagonal bolt head 13 is clamped and rotated anticlockwise through the wrench, at the moment, the limiting column 2 drives the gear 3 to rotate anticlockwise, the pull plate 1 can be drawn into the shell 12 due to the mutual meshing of the gear 3 and the tooth block 6, the distance between the pull plates 1 is changed, so that the bridge road surface at two sides of the crack is pulled to be healed, when the pulling limit of the device is reached, the pull bolt 11 can be downwards hammered, so that the second limiting pin 18 is clamped into the second pin hole 16, the locking of the device is completed, the device is simple and effective, when the device needs to be rearranged, only a tool is used for pulling the pull bolt 11, the limiting column 2 drives the second limiting pin 18 to leave the inner part of the second pin hole 16, so that the device can be pulled and clamped again, and the actual use effect of the device is good.
