Abstract
A lifter to maintain vehicle comprises a lift mechanism and a hydraulic drive mechanism. The lift mechanism comprises a crotch and an arm plate, and the hydraulic drive mechanism comprises a control box, a pump valve, a motor, a hydraulic cylinder, etc., and the lifter to maintain vehicle is characterized in that the hydraulic cylinder are placed upright, and the top of a piston rod of the hydraulic cylinder is connected with a movable pulley, and one end of a chain belt of the movable pulley and the other end of it integrates the crotch as an entirety. The crotch has a frame structure, and the hydraulic drive mechanism is in the other side of the lift mechanism to have a function of centralized control and convenient maintenance. A location mechanism composed of a positioning box and a reference column is located between the lift mechanism and the hydraulic drive mechanism to have a fixing and spacing function.
Description
The utility model is a kind ofly to be used for various power actuated vehicles the maintenance lift car is arranged.
Also do not have a kind of hydraulic lift that is specifically designed to the self-propelled vehicle maintenance with regard to present, and existing various load-carrying hydaulic lift platform is because the restriction of self structure can not perform well in the maintenance of self-propelled vehicle.
The purpose of this utility model is to provide a kind of hydraulic up-down car that is used for the workover rig motor vehicle.
The utility model is achieved in that lift car is made up of lifting mechanism, hydraulic drive mechanism, wherein, lifting mechanism comprises crotch and arm plate, one end of arm plate is connected with crotch, and the other end is connected on the fixed frame, and hydraulic drive mechanism comprises control box, pump, valve, motor, oil cylinder, it is characterized in that oil cylinder is upright placement, the top of oil cylinder piston bar is connected with a movable pulley device, and chain one end on the movable pulley is fixed, and the other end and crotch are connected as a single entity.
Fig. 1 is the lateral plan of the design embodiment.
Fig. 2 is the front elevation of embodiment.
Fig. 3 is a movable pulley device scheme drawing.
Below in conjunction with embodiment the design is described in detail.
Lift car mainly is made up of lifting mechanism and hydraulic drive mechanism, wherein, lifting mechanism comprises crotch 1 and two arm plates 2, one end of arm plate 2 is connected on the fixed frame 3, hydraulic drive mechanism comprises control box 4, pump 5, motor 6, oil cylinder 7 and valve etc., it is characterized in that oil cylinder 7 is upright placement, and the piston rod part of oil cylinder 7 is connected with a movable pulley device, chain 9 one ends on the movable pulley 8 are fixed by nut, and the crotch 1 that the other end and channel-section steel are made is connected as a single entity.
In addition, for centralized control, convenient for maintaining, crotch 1 is a framed structure, and the centre is empty, and the control box 4 in the hydraulic drive mechanism, pump 5, motor 6, oil cylinder 7 and valve etc. all are positioned at the opposite side of lifting mechanism.
Moreover, for the lifting and the fixing of crotch 1 of realizing crotch 1 better reaches hoisting position, between lifting mechanism and hydraulic drive mechanism, set up detent mechanism, this detent mechanism is made up of registration mast 10 and location case 13, registration mast 10 is provided with knock hole 12 by certain spacing from bottom to top, location case 13 is socketed on the registration mast 10, and location case 13 is connected as a single entity with crotch 1 again.Registration mast 10 and hydraulic drive mechanism all are fixed on the beam supporting plate 14 of lifting mechanism side.
And the location also is provided with position fixing handle 15 and locating dowel pin 16 on the case 13, by stirring the upper and lower position of position fixing handle 15, can make crotch 1 promote location case 13 and hoist with the spacing between the knock hole 12 and locate along registration mast 10 together.
Also have, in the front end both sides of beam supporting plate 14 supporting leg 18 that has rotary handle 17 is set respectively, in maintenance work, to play the single-piece supporting role.
In lifting mechanism, an end and the crotch 1 of one of them arm plate are affixed, and the other end and underframe 3 flexibly connect, and an end of another arm plate and crotch flexibly connect, and the other end and underframe 3 are affixed.
The design is hand propelled maintenance lift car, and push rod 19 is positioned at the front center of beam supporting plate 12, a roller 20 is arranged below the push rod 19, and the both sides of underframe 3 equally also are provided with two rollers 21.
By manual starter 22 full voltage startings, driven by motor pump, valve work make the piston rod of oil cylinder drive the movable pulley device, and then make chain drive crotch, and crotch promotes the location case and hoists along registration mast jointly.Control in-oil cylinder oil mass by a hand change over valve, and then play control crotch lifting and static effect.
The utility model is by the improvement to existing hydaulic lift platform, especially oil cylinder is changed into upright shape and pass through a movable pulley device, enable to service a car, and crotch is a framed structure, hydraulic drive mechanisms etc. all are arranged on a side of lifting mechanism, keep in repair convenient.
Accompanying drawing has other explanation:
23--chain guard 24--handgrip 25--support.
