Background technology
Hydaulic lift platform is a kind of jacking system that generally uses in various mechanical equipments.The structure of common hydaulic lift platform as shown in Figure 3, it comprises base, bearing surface and hydraulic-driven part in constituting, in the both sides of base the scissor-type bracing frame is installed, the hinged place of two bracing frames connects with bearing pin, and the roller of base rolling relatively is equipped with in lateral branch support lower end.The hydaulic lift platform of this conventional confguration has following problems: 1. bay-lift unbalance stress, and poor stability causes bearing surface to rock, thereby influences the reliability of bay-lift work; 2. the bearing pin connection mode friction drag of bracing frame hinge is big, and parts depreciation is serious, and service life is short.
Summary of the invention
The utility model is used to solve the defective of above-mentioned prior art and a kind of stress equalization is provided, supports steady failure-free hydaulic lift platform.
The alleged problem of the utility model solves by the following technical programs:
A kind of hydaulic lift platform, comprise base, bearing surface, scissor-type bracing frame and hydraulic actuating cylinder in the formation, one side of described scissor-type bracing frame is hinged with base and bearing surface respectively, its special feature is: described bay-lift also is provided with the rolling slide block guide rail mechanism, described rolling slide block guide rail mechanism is made up of guide rail and rolling slide block, both constitute moving sets, its motion contact surface is a friction of rolling, described guide rail is fixed with base and bearing surface respectively, and the opposite side of described rolling slide block and scissor-type bracing frame is hinged.
Above-mentioned hydaulic lift platform, the cross section of described guide rail are criss-cross, and described rolling slide block is a square frame shape, and guide rail is positioned at this square frame, and each frame body middle part of described rolling slide block is provided with the roller bearing of back-shaped configuration.
Above-mentioned hydaulic lift platform, described roller bearing two ends are provided with retainer, and retainer is inlaid in the module, and module is inlaid in the frame body place of rolling slide block.
Above-mentioned hydaulic lift platform, the hinged place of hinged place, bracing frame and base, bracing frame and the bearing surface at described scissor-type bracing frame middle part is equipped with needle bearing.
The utility model improves at common hydaulic lift platform poor stability, problem that functional reliability is low, its characteristics are embodied in following aspect: 1. rolling slide block guide rail mechanism design makes the bay-lift good stability, when being subjected to the load of all directions, the bearing surface of hydaulic lift platform all can guarantee the balance of table top, both ensure the reliable of work, and protected hydraulic actuating cylinder not bear the influence of capsizing moment again; 2. the vice division chief that moves in relative rotation that respectively has of bay-lift is and rolls stressedly, and friction drag is little, and all rollers are evenly stressed, has prolonged the service life of roller effectively.3. all movable parties have all limited five degree of freedom, and it can only be rotated or translation according to design direction, make bay-lift have higher functional reliability.
