Abstract
The utility model belongs to the technical field of telescopic devices and discloses a universal displacement telescopic device. The universal displacement telescopic device is technically characterized by comprising a middle beam and edge beams. A Sealing rubber strips are arranged between the middle beam and the edge beams, a supporting cross beam with displacement box bodies at the two ends is arranged below the middle beam and the edge beams, the middle beam and the edge beams are interconnected via a synchronous chain plate, comb-shaped steel plates are arranged on the middle beam and the edge beams and engaged with each other, and a height adjusting pad is arranged below the middle beam. According to the universal displacement telescopic device provided by the utility model, the comb-shaped steel plates are arranged on the middle beam and the edge beams and engaged with each other, so that when a vehicle passes through, a smooth transition is provided to not only reduce the noise but also reduce the impact force generated when the vehicle passes through, thereby reducing the formation of cracks and greatly increasing the service life of the telescopic device. The height adjusting pad which is arranged below the middle beam can adjust the mounting height of the middle beam to facilitate the installation and maintenance.
Description
Technical field
The utility model belongs to the stretching device technical field, relates in particular to a kind of universal displacement stretching device.
Background technology
Bridge extension joint comprises central sill and side bar, is provided with sealing joint strip between central sill and side bar, and central sill and side bar are arranged with the bearing cross beam that two ends are the displacement casing, and chain template parallelogram synchronous shift system is installed on stretching device.This stretching device is when vehicle passes through; Can produce very big impact force to the side bar deformed steel, produce very big noise, excessive impact side bar can make the side bar deformed steel deform simultaneously; Deformed steel and concrete take place produce the crack; Make impurity such as water get into the crack, the connecting reinforcement of stretching device is corroded the service life of minimizing stretching device.In addition, the central sill setting height(from bottom) can not be adjusted, and causes certain influence to installation and maintenance.
The utility model content
It is little that the technical problem that the utility model will solve just provides a kind of noise, long service life, the universal displacement stretching device of easy installation and maintenance.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise central sill and side bar; Be provided with sealing joint strip between central sill and side bar, central sill and side bar are arranged with the bearing cross beam that two ends are the displacement casing, and central sill is connected through synchronous carrier bar with side bar; Be provided with the comb shaped steel plate that is complementary above said central sill and the side bar, central sill is arranged with heightens cushion block.
Its additional technical feature is: the cross section of said central sill and side bar is C type, G type, Z type, E type, F type.
The universal displacement stretching device that the utility model provided compared with prior art; Be provided with the comb shaped steel plate that is complementary above central sill and the side bar; When vehicle passed through, smooth transition had not only reduced noise and has also reduced the impact force that produces when vehicle passes through like this; Reduced the appearance in crack, improved the service life of stretching device greatly.And central sill is arranged with and heightens cushion block, can realize the adjustment of central sill setting height(from bottom), helps installation and maintenance.As required, the cross section of central sill and side bar can be C type, G type, Z type, E type, F type.
