Further, in this utility model, described coaster is provided with U-shaped framework, is provided with and fixes the main shaft being connected with U-shaped framework in described U-shaped framework, and described continuous track formula roller surrounds on described main shaft。The present invention adopts U-shaped frame structure, and its bearing capacity is big, it is possible to suitable in the sliding of the bigger works of weight。
Further, described carriage bottom is provided with the roller trolley pedestal being fixed together with carriage, described jack power transmission pedestal bottom is provided with spacing adjustment pedestal, on described spacing adjustment pedestal, the bottom corresponding to jack power transmission pedestal is respectively provided on two sides with pedestal limiting plate at it, the bottom of described jack power transmission pedestal is positioned at the slideway formed by two pieces of pedestal limiting plates, being additionally provided with jack counter-force pedestal on described spacing adjustment pedestal, described jack is connected with jack counter-force pedestal。Can ensure that the transverse shifting in jack power transmission pedestal loading process by pedestal limiting plate and prevent that moving process occurs raw inclination。
For ease of works carries out effectively spacing and correction, described spacing adjustment roller is preferably located at the rear flank portion of described coaster。
This utility model has the advantage that
1, adopt the coaster with continuous track formula roller as slideway, the rolling friction utilizing roller reduce further horizontal frictional resistance, its frictional resistance is little, speed of application is fast, construction period can be shortened, can saving the cost such as equipment, electric power, and can apply a cross force to works and reach the effect of correction by adjusting jack, spacing adjustment roller can the direction of travel of limiting structure thing simultaneously;Reliability of the present invention is high, it is ensured that the safety of works sliding。
2, this utility model can realize works and carries out spacing adjustment in running, effectively reduces the time under static adjustment, improves construction safety coefficient, and save human cost。
3, this utility model simple structure, principle is understandable, it is easy to make, with low cost to install, and has higher practicality。
