Abstract
The utility model relates to a stand bar chassis. The stand bar chassis comprises a ball head stay, a ball head cap, a ball socket, a ball, a ball rack, a spring, a chassis, a cover body and the like. A ball head of the ball head stay is positioned inside the ball socket. The ball head cap is connected with the ball socket through a bolt, so that the ball head stay can not break away from the ball socket. The ball is placed inside a ball pit of the chassis, and the ball rack is connected with the chassis through the bolt so that the position of the ball is fixed but the ball can rotate. The pressure spring is sleeved outside the ball rack. The cover body is connected with the chassis through the bolt in order to restrict the activity ranges of the ball socket. According to the stand bar chassis, the chassis with the ball is added based on the common stand bar chassis to enable the ball socket to have a certain activity range inside a plane. The stand bar chassis can achieve the requirements of spacing changes of a stand bar in a four-stand-bar hydraulic synchronous climbing mechanism.
Description
Technical field
The utility model relates to a kind of leg chassis.
Background technique
When equipment adopts four leg hydraulic synchronization lifting mechanisms, in the time of need to carrying out pitching or roll adjusting, because leg ball head stay extrusion is different, so that the leg spacing changes, need the leg chassis to have certain spacing to regulate.The leg chassis structure that uses at present mainly is comprised of ball head stay, ball-and-socket and bulb lid etc., because ball-and-socket directly supports on the ground, the surface friction drag on ball-and-socket and ground is very large, so that the adjusting requirement that the leg spacing changes can't be realized in this kind leg chassis.
The model utility content
Technical problem to be solved in the utility model is: a kind of leg chassis of realizing leg spacing regulatory function in the four leg hydraulic synchronization lifting mechanisms is provided.
The technical solution of the utility model is: a kind of leg chassis, comprise ball head stay 1, bulb lid 7, ball-and-socket 2, the bulb of ball head stay 1 is placed in the ball-and-socket 2, bulb lid 7 links to each other with ball-and-socket 2 by screw, and it is characterized by: described leg chassis also comprises ball 3, ball rack 4, chassis 6 and cover body 8; Ball 3 is placed in the ball nest on chassis 6; Ball rack 4 places ball 3 tops, and has the ball hole of restriction ball 3 the sphere of activities; Ball rack 4 is connected and fixed by screw and chassis 6; Cover body 8 passes through the movable chamber that screw 9 links to each other with chassis 6 and forms ball-and-socket 2; Ball-and-socket 2 places ball rack 4 tops and contacts with ball 3.
The beneficial effects of the utility model are: this model utility increases the chassis with ball on basis, common leg chassis, ball-and-socket is floated to be placed on the ball, certain the sphere of activities can planar be arranged, realized the requirement that the leg spacing changes in the four leg hydraulic synchronization lifting mechanisms.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model leg base;
Fig. 2 is the transverse sectional view of a kind of embodiment of the utility model leg base shown in Figure 1;
Wherein, 1-ball head stay, 2-ball-and-socket, 3-ball, 4-ball rack, 5-spring, 6-chassis, 7-bulb lid, 8-cover body, 9-screw.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to Fig. 1, Fig. 2, a kind of embodiment of the present utility model mainly comprises ball head stay 1, ball-and-socket 2, ball 3, ball rack 4, spring 5, chassis 6, bulb lid 7, cover body 8 and screw 9, ball head stay 1 is positioned in the ball-and-socket 2 by bulb lid 7, can turn an angle in ball-and-socket simultaneously; Ball-and-socket 2 floating being placed on the ball 3; Ball 3 is placed in the ball nest on chassis 6; Ball rack 4 places ball 3 tops, and has the ball hole of restriction ball 3 the sphere of activities; Ball rack 4 is connected and fixed by screw and chassis 6; Ball 3 is positioned in the ball nest on the chassis 6 by ball rack 4; Cover body 8 passes through the movable chamber that screw 9 links to each other with chassis 6 and forms ball-and-socket 2; Ball-and-socket 2 places ball rack 4 tops and contacts with ball 3.Cover body 8 passes through the movable chamber that screw 9 links to each other with chassis 6 and forms ball-and-socket 2, the sphere of activities of restriction ball-and-socket 2; Spring 5 is sleeved on ball rack 4 outsides, between ball-and-socket and chassis, when the float base integrated hanging, makes chassis and ball head stay dead in line.
During use, when four leg hydraulic climbing mechanisms carry out pitching or roll adjusting, because wherein two leg extrusions of two leg ball head stay extrusions and other are different, therefore the spacing on different extrusions chassis must increase, this moment, ball-and-socket slided by the ball that ball head stay drives on the chassis, realized the requirement that the chassis spacing increases.
The utility model has been realized the variation requirement of leg spacing when four leg hydraulic climbing mechanism pitching or roll are regulated by increase the method on ball chassis under common leg chassis.
