Abstract
The utility model relates to an automatic maintenance lifting device, which is a lifting device mainly used for an automatic gear case. The utility model comprises two groups of rectangle hinge mechanisms (1), a screw (2), a pair of transmitting gears which are a driver (3) and a driven wheel (4), an expansion bracket (5), a locating bearing (6), an upper frame (7) and an under frame (8). A ceiling disc (17) can be arranged on the upper frame. A chassis (18) and a roller (19) can be arranged on the under frame. The upper part of the rectangle hinge mechanism supports and fixedly connects with an upper frame (7), and the lower part is connected with an under frame (18) in fixed connection. Two lateral sides of the rectangle hinge mechanisms are separately connected with a front cross bar (9) and a back cross bar (10) of the expansion bracket (5) in hinge connection. The rectangle hinge mechanisms (1) are connected with the upper frame (7) and the lower frame (8), and the joint part of two hinges are meshed by using partial teeth (21). The screw (2) is sheathed on screw sleeves (11), (12) fixed on the front cross bar and on the back cross bar. The arrangement of the screw sleeve uses internal threads which are arranged in a symmetrical form. The front end of the screw is connected with the driver in fixed connection. A driving bearing (20) is arranged between the screw and the driven wheel. The teeth of the driver are combined with the teeth of the driven wheel. The front end of the driver is closely combined with the bearing which locates in the locating bearing. The end of the driver is connected with a handle (13). The extension bracket comprises a basal sleeve (14), a middle sleeve (15) and an inserted end (16). The utility model has the advantages of simple structure, convenient operation, safety and stability.
Description
Technical field:
The utility model belongs to elevating gear, especially vehicle maintenance and repair jacking equipment technical field.
Background technology:
Existing vehicle maintenance and repair jacking system mainly is that crane in bridge type and cucurbit hang.But the lifting, the lifting appliance that are used for automobile gearbox still lack specialized equipment.Maintenance at present is used to lift the method for automobile gearbox, mainly is that this method is not only dangerous but also waste time and energy, and causes casing and heavy mail corrupted easily by the lifting of manpower stay cord.Even adopt cucurbit to hang,, also be easy to generate and come off or safety misadventure takes place because the structure of the weight of change speed gear box and automobile also extremely is inconvenient to lift.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure for the weak point that overcomes above-mentioned prior art existence just, and is easy to operate, the vehicle maintenance and repair jacking system of safety and stability.
The purpose of this utility model is achieved by the following technical solution:
It is that driving wheel and flower wheel, expansion bracket, location bearing and upper frame and underframe are formed by two groups of rectangle linkages, screw rod, an a pair of transmission gear; The upper support of rectangle linkage and captive joint upper frame, the bottom captive joint underframe of rectangle linkage; The two side ends of rectangle linkage hinge respectively is connected on the forward and backward cross bar of expansion bracket, and screw rod is inserted in screw rod fixing on the forward and backward cross bar and puts, and the form that adopts negative thread to be symmetry that is provided with of screw rod cover is installed.The front end of screw rod is captiveed joint with flower wheel, and the teeth of driving wheel match with the teeth of flower wheel, and the bearing in the front end of driving wheel and the location bearing closely cooperates handle of end joint connection.Expansion bracket is made up of for three sections end sleeve, middle sleeve, insertion section.
It rotates driving gear by motor or handle, drives and gently rotates from gear, orders about the screw rod rotation from gear, and two screw rods that are fixed on the expansion bracket put.Because of relative straight-line displacement takes place in the rotation of screw rod different aspect, because the negative thread of two screw rods covers is the reverse screw mode,, the rotation of screw rod stretches so driving expansion link, two groups of rectangle linkages also raise or reduce because of stretching with contracting of expansion bracket.Thereby the hinge-rod that impels four link type of drawing close and draw back of the front and back cross bar on the expansion bracket moves up and down respectively and reaches the purpose of push rod lifting, because the hinge place at push rod is provided with carriage or pallet, and then the effect by push rod holds up the equipment on the carriage or put down.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the dextrad view of Fig. 1;
The specific embodiment:
Rectangle hinge arrangement 1 adopts the metal tube of wall thickness to make, and its hinge connection both can adopt general hinge, also can adopt the bearing-type hinge.What the utility model was selected for use is two groups of rectangle hinge arrangements 1, its eight shed sticks adopt local tooth 21 engagements in the outside at the place of tangling of upper frame 7 and underframe 8 meeting points, to prevent that hinge from skidding, screw rod 2 will be longer than expansion bracket 5 from vertically going up, and expansion bracket 5 is end sleeve 14, middle sleeve 15, is inserted sections 16 and be socketed to form respectively by three metal tubes.Middle sleeve 15 inserts end sleeve 14, inserts section 16 and inserts middle sleeve 15.Its function is mainly used in the flexible of expansion link, whole expansion bracket 5 is a U font, each weldering of two ends connects one section front rail 9 and rear transverse rod 10, screw rod cover 11,12 is welded in respectively on the forward and backward cross bar center, screw rod cover 11,12 its negative thread directions are symmetry and place, push away or spur forward and backward cross bar to order about screw rod 2, thereby tear rectangle linkage 1 up-and-down movement.Driving device is made up of driving wheel 3, flower wheel 4, location bearing 6, drive bearing 20, rocking bar, handle 13.Driven wheel is the gear of pair of meshing, and location bearing 6 is welded on the front rail 9, and cover closely cooperates with screw rod 2 in the drive bearing 20.For ease of using, on the utility model upper frame 7, be welded with 17, take over a business on 17 and can design the structure that matches with the change speed gear box profile, so that stably hold gear case.On underframe 8, be connected with four rolling 19 so that move.
