Abstract
The utility model relates to an autocrane, particularly relates to a sliding device for a horizontal support oil cylinder of the autocrane, and belongs to the technical field of machining. The sliding device comprises sliding blocks additionally arranged on the lower end surface of a movable support leg; and the sliding blocks are directly connected with a sliding support leg through screws and directly in contact with a fixed support leg. When the movable support leg is moved, the sliding blocks are worn, at the same time, the surface contact is changed into the point contact, so that the using situation of the movable support leg is improved, the service life of the movable support leg is prolonged, the maintenance cost of the movable support leg is reduced, and the maintenance is simple and convenient.
Description
Technical field
The utility model relates to a kind of car hosit, is specifically related to a kind of carriage of car hosit horizontal support legs oil cylinder, belongs to the Machining Technology field.
Background technology
Known car hosit horizontal support legs motion structure is that cross cylinder cylinder head one end is connected with fixed supporting leg by bearing pin, the other end is connected with movable supporting legs with bearing pin by the pin shaft hole on the piston rod, movable supporting legs is done cross motion by stretching of cross cylinder in fixed supporting leg, this kind design drawback is: horizontal support legs is when doing cross motion, direct and fixed supporting leg joint, horizontal support legs outside, because the quality of self is big, contact surface is bigger, make horizontal support legs and fixed supporting leg produce bigger wearing and tearing, the actual contact point of horizontal support legs and fixed supporting leg produces uncertain, make that the whole stressing conditions when horizontal support legs is movable is not good, at any time use the increase of time, make its mode of operation more abominable, thereby influence the service life of supporting leg, increase its maintenance cost.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of carriage of car hosit horizontal support legs oil cylinder is provided, this device is included in the movable supporting legs lower surface increases slide block, and slide block is by screw and slip supporting leg direct connection, with the fixed supporting leg direct contact.When movable supporting legs moves, make slide block produce wearing and tearing, change the face contact into a some contact simultaneously, the condition of service of movable supporting legs is improved, when increasing its life-span, can reduce its maintenance cost, easy maintenance.
The utility model is realized with following technical scheme: a kind of carriage of car hosit horizontal support legs oil cylinder, it includes cylinder block, cylinder block one end is connected with fixed supporting leg by first bearing pin, the cylinder block other end is connected with movable supporting legs by second bearing pin on the piston rod, it is characterized in that: there is slide block described movable supporting legs lower surface by screw retention.
Described movable supporting legs lower surface is fixed with several slide blocks.
The utility model has the advantages that: this device is included in the movable supporting legs lower surface increases slide block, and slide block is by screw and movable supporting legs direct connection, with the fixed supporting leg direct contact.When movable supporting legs moves, make slide block produce wearing and tearing, change the face contact into a some contact simultaneously, the condition of service of movable supporting legs is improved, when increasing its life-span, can reduce its maintenance cost, easy maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is the utility model structural representation:
Among the figure: 1, first bearing pin, 2, cylinder block, 3, fixed supporting leg, 4, piston rod, 5, movable supporting legs, 6, slide block, 7, screw, 8, second bearing pin.
The specific embodiment
As shown in the figure: a kind of carriage of car hosit horizontal support legs oil cylinder, it includes cylinder block 2, cylinder block one end is connected with fixed supporting leg 3 by first bearing pin 1, the cylinder block other end is connected with movable supporting legs 5 by second bearing pin 8 on the piston rod 4, and described movable supporting legs 5 lower surfaces are fixed with slide block 6 by screw 7.
Described movable supporting legs 5 lower surfaces are fixed with several slide blocks 6.
Working process: this device is included in the movable supporting legs lower surface increases slide block, and slide block is by screw and movable supporting legs direct connection, with the fixed supporting leg direct contact.When movable supporting legs moves, have only the friction of slide block and fixed supporting leg, have only slide block that wearing and tearing are arranged, but at high speed is more sliding after the wearing and tearing, can increase the service life of mechanism, slide block and fixed supporting leg direct contact play directional tagging.
Claims (2)
