Description

Pressure locating guide device
Technical field
The present invention relates to mechanical equipment technical field, and in particular to pressure locating guide device.
Background technology
In tower crane lifting process, the guider branch on the crossbeam of jacking stock is fixedly connected in standard section of tower crane master On the outside of chord member, play guided bearing, and can move up and down.If guider and main chord of standard section in lifting process It is unable to reliable contacts, the standard knot of bottom(Fixed component)Cannot operative constraint tower crane top movable part, apply lifting Work produces very big potential safety hazard, it is likely that triggers serious accident.Therefore, guider is needed to use to prevent here This problem.
Guider is relatively common parts in conventional mechanical devices, and in general guider is all to fix not Dynamic, spigot surface is vertically had no problem, but relative motion can be often produced between two parts up and down of tower crane, using normal The guider of rule can not solve the problem.
Application No. 201020186994.8, entitled tower crane add, dropped the Chinese utility model patent of section guider public A kind of tower crane lifting and guiding device is opened, it includes directive wheel, guide wheel shaft, directive wheel fixed plate, directive wheel connecting plate, attached Fixed plate and fixing bolt;Directive wheel is installed in directive wheel fixed plate by guide wheel shaft, and directive wheel fixed plate, which is fixed, to be connected It is connected to the side of directive wheel connecting plate;The position up and down of directive wheel connecting plate and attached fixed plate is correspondingly provided with bolt connection respectively Hole, and the spacing between the bolt connecting hole at position is more than or equal to the crossbeam of tower crane jacking stock in the height direction up and down Thickness, attached fixed plate pass through the fixation that is arranged between its bolt connecting hole and the corresponding bolt connecting hole of directive wheel connecting plate Bolt connection can effectively ensure that tower crane directive wheel and main chord of standard section in lifting process in the opposite side of directive wheel connecting plate Reliable contacts, to constrain the superstructure of tower crane, it is ensured that the safe construction in tower crane lifting process.The program uses two guiding Wheel blocks main chord of standard section from two faces, thus can effectively ensure directive wheel and main chord of standard section reliable contacts, It is larger to the frictional force of main chord so that main chord is more easy to grind but two guide rods of this structure directly contact main chord Damage, reduces service life;It can not also be automatically adjusted when unbalance loading occurs, make guiding that deviation occur, cause tower crane to lift When produce guider and the insecure problem of main chord of standard section reliable contacts, have impact on the security of tower crane.
The content of the invention
It is an object of the invention to for deficiency of the prior art, and pressure locating guide device is provided, it can subtract Small directive wheel improves the service life of tower crane to the frictional force of main chord;Meanwhile it can solve the problem that between directive wheel and main chord During generation unbalance loading, it can not automatically adjust and to be oriented to the problem of deviation occurs.
The purpose of the present invention is achieved through the following technical solutions:
Pressure locating guide device is provided, including square body outer box and the interior inner cylinder for being placed on the outer box, inner cylinder are separated into by dividing plate Ante-chamber and back cavity;Wherein, pressurization oil cylinder is provided with ante-chamber, pressurization oil cylinder is provided with oil inlet and outlet, and pressurizes between oil cylinder and inner cylinder Gap it is relative be provided with one group of extension spring, be additionally provided with soft isolating device, in addition to end cap, end cap between extension spring and pressurization oil cylinder Pressurization oil cylinder is fixed on ante-chamber;Multiple directive wheels are provided with back cavity, back-moving spring is provided between directive wheel and the dividing plate.
Wherein, the quantity of directive wheel is two, and corresponding back-moving spring quantity is four.
Wherein, square body spacing block is provided between two directive wheels, two directive wheels are symmetrically arranged at the two of spacing block Side.
Wherein, end cap is the cover plate provided with multiple screws, and being provided with the middle part of cover plate can be exposed to the oil inlet and outlet of compressing cylinder The through hole of ante-chamber.
Wherein, cover plate is circular metal plate, and the multiple screw is uniformly at its outer ring.
Wherein, end cap is relatively set with detent.
Wherein, soft isolating device is the isolating device made of soft rubber.
Beneficial effects of the present invention:
Tower crane is in lifting, it is necessary to guider and main chord of standard section reliable contacts, the standard knot of bottom(Fixed component) The movable part on energy operative constraint tower crane top;Using pressure locating guide device provided by the invention, its directive wheel with every Back-moving spring is provided between plate, back-moving spring when directive wheel is by certain pressure, the compressible back-moving spring of directive wheel to In shrink certain distance so that relatively reasonable pressure is kept between directive wheel and main chord, prevent to some extent master The excessive wear of swing arm, add the service life of tower crane.Meanwhile when serious unbalance loading occurs, due to the extension spring in ante-chamber Soft isolating device is additionally provided between pressurization oil cylinder, the relative position that the soft isolating device causes extension spring between the oil cylinder that pressurizes A certain degree of regulation can be carried out by putting, and during unbalance loading generation, soft isolating device can be adjusted correspondingly automatically, so that with Back-moving spring among back cavity cooperates to be modified to unbalance loading.
