Technical problem to be solved in the utility model is to provide a kind of car hosit Vertical Cylinders backing plate, lightweight, is easy to remove and install.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of car hosit Vertical Cylinders backing plate, comprise base, support, support is fixed on base by several screws, base comprises pedestal, liner, lining, pedestal adopts non-metallic material, bottom it for cylinder, middle part be cone, top is that round boss, the end face upwards extended is provided with step circular groove and the some blind holes around circular groove; Liner adopts metallic material, and for being with the disc structure of boss, its end face center is provided with spherical groove; Lining adopts metallic material, and be the column structure of bottom belt boss, center is provided with internal thread hole; Liner, lining are nested in circular groove, the blind hole inside of pedestal respectively;

Support adopts metallic material, and comprise two parallel arc side plates, be positioned at U-shaped base plate bottom two arc side plates, U-shaped base plate is provided with several through holes corresponding with blind hole quantity and position.

In the utility model preferred embodiment, pedestal, liner, lining are that mould is one-body molded, are embedded as a whole with liner, lining when pedestal is shaping, to ensure to be connected firmly.

The beneficial effects of the utility model are: the utility model structure is simple, lightweight, be easy to remove and install, convenient in carrying, and metallic support realizes the connection of whole backing plate and Vertical Cylinders, simple installation; Non-metal base can meet the support function of backing plate, greatly reduces the weight of backing plate simultaneously, reduces labour intensity during handling; Liner contacts with Vertical Cylinders disputer, uses metallic material to make, can meet intensity and resistance to abrasion demand; The tapped bore at lining center adopts metallic material to make the screwing force requirement that can meet screw, connects more reliable; Sleeve, with boss, can ensure to inlay firmly with pedestal, get loose after avoiding long-term tension.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of car hosit Vertical Cylinders backing plate, comprise base 1, support 2, support 2 is fixed on base 1 by several screws 3, becomes an integral structure.As shown in Figures 2 and 3, base 1 comprises pedestal 11, liner 12, lining 13, composition graphs 4 and Fig. 5, for reducing the weight of whole backing plate, be convenient to dismounting, pedestal 11 adopts non-metallic material, it is cylinder bottom it, middle part is cone, top is the round boss upwards extended, end face is provided with step circular groove 111 and the some blind holes 112 around circular groove 111, pedestal 11 utilizes mould one-body molded, and in advance liner 12 and lining 13 are imbedded before casting, it is made to be set into as a whole, to ensure to be connected firmly, circular groove 111 is positioned at the center of pedestal 11, for inlaying liner 12, its scantling of structure depends on the oad of liner 12, blind hole 112 is for inlaying lining 13, its scantling of structure depends on the oad of lining 13, the quantity of quantity and lining 13 is consistent.Non-metal base 1 can meet the support function of backing plate, greatly reduces the weight of backing plate simultaneously, reduces labour intensity during handling.

Refer to Fig. 6, liner 12 adopts metallic material, and for being with the disc structure of boss, its end face center is provided with spherical groove 121.When automobile crane machine operation, the bulb of Vertical Cylinders end sinks in spherical groove 121, and both contact with each other with transmitting forces, adopts metallic material liner 12 can meet intensity and resistance to abrasion demand.Refer to Fig. 7, lining 13 adopts metallic material, and be the column structure of bottom belt boss 132, center is provided with internal thread hole 131, for the connection of screw 3.Adopt metal lining 13 can meet the screwing force requirement of screw 3, make to connect reliable, avoid appearing at and non-metal susceptor 11 opens tapped bore cause screw 3 screwing force not enough, connect loosely, loosen, the even situation of Joint failure; Be provided with boss 132 bottom lining 13, can ensure to inlay firmly with pedestal 11, get loose after avoiding long-term tension.

Refer to Fig. 8 and Fig. 9, support 2 adopts metallic material, and comprise two parallel arc side plates 21, be positioned at U-shaped base plate 22 bottom two arc side plates 21, U-shaped base plate 22 is provided with several through holes 23 corresponding with blind hole 112 quantity and position.Screw 3, through through hole 23, is screwed in the internal thread hole 131 of lining 13, is fixed on base 1 by support 2.Metallic support 2 realizes the connection of whole backing plate and Vertical Cylinders, simple installation, and when car hosit is in motoring condition, even if Vertical Cylinders rises, the bulb of its end leaves spherical groove 121, two arc side plates 21 and the Vertical Cylinders of support 2 still keep coupled condition, thus make car hosit can carry backing plate synchronously to travel.

The utility model structure is simple, lightweight, be easy to remove and install, convenient in carrying, is equally applicable to the supporting-foot base plate of other type construction machinery and equipment.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
