Embodiment 2

[0037] Example 2: Such as figure 1 , Figure 5 to Figure 7 , Another preferred embodiment of the present invention: a platform level automatic adjustment device, including a platform 12, air springs 6 are installed under the four corners of the platform 12, the air springs 6 and the lifts installed in the support legs 3 The upper end of the mechanism 5 is connected, and the lower end of the elevating mechanism 5 is connected with the transmission device 4, and the transmission device 4 drives the elevating mechanism 5 to adjust the platen 12. A support B15 is installed at the middle position below the platen 12. The support B15 is composed of a seat body 16, a pole 17 and a ball head B26. The center of the seat body 16 is fixed with a pole 17, and the end of the pole 17 is a ball head B26. , The pole 17 is sleeved with a snap ring 18 . The snap ring 18 is circular, with threads on the outer periphery, and a concave arc surface matching the shape of the ball head B26 on the...

Embodiment 3

[0039] Example 3: A platform level automatic adjustment device, the cantilever 2 is in the shape of "Y", see Figure 9 , and the connecting line of its ends is an equilateral triangle or an isosceles triangle. Others are identical with embodiment 1 or embodiment 2.

Embodiment 4

[0040] Example 4: An automatic adjustment device for platform level, the cantilever 2 is in the shape of a "ten", and the connection line at the end is in the shape of a square or a rhombus. Others are identical with embodiment 1 or embodiment 2.

[0041] The steps of the adjustment method of an automatic platform level adjustment device in the present invention are as follows: first, the joint connection between the dead weight of the plumb weight 10 and the center of the swing rod 8 is used, and when the horizontal position of the platform 12 deviates, the swing rod 8 will always Pointing to the center of the earth, now the cantilever 2 keeps the horizontal position all the time. The vehicle-mounted platform has four supporting legs 3, which are divided into three groups, one of which includes two supporting legs 3, and three regulating air valves 1 respectively control the corresponding air springs 6, so as to control the lifting of the air springs 6 in the supporting lif...

Abstract

The invention discloses an automatic horizontal adjusting device and adjusting method for platform. The automatic horizontal adjusting device for the platform comprises a bedplate, wherein an air spring is mounted under each corner of the bedplate, the air springs are connected with the upper ends of lifting mechanisms mounted in support legs, the lower ends of the lifting mechanisms are connected with transmission devices, a base is arranged under the support legs, a support seat A is mounted in the middle position under the bedplate, adjusting gas valves are also fixedly mounted under the bedplate, the adjusting gas valves are connected with the air springs through gas pipes, one end of a swing rod is provided with a spherical head A and is fixed by a clamp sleeve sleeved on the exterior of the support seat A, the other end of the swing rod is provided with a plumb bob, a suspension arm is mounted on the rod body of the swing rod, the end head of the suspension arm is correspondingly positioned under contact points of the adjusting gas valves, a locking plate is fixedly arranged on the base, and a movable magnet block inside the plumb bob controls the locking through a remote control switch. The invention also provides the horizontal adjusting method for the platform, and the horizontal adjusting device and the adjusting method have the characteristics that the horizontal adjusting time is short, the horizontal adjusting accuracy is high, the reliability is high and the like.

Description

technical field [0001] The invention relates to the field of working machinery, in particular to a platform level automatic adjustment device and adjustment method for multi-point support mainly for vehicle-mounted equipment. Background technique [0002] During the use of mobile equipment, there are usually horizontal requirements for the installation surface of the equipment. However, due to factors such as terrain with a certain slope and geological structure, it is required that the platform should always be level with the horizontal plane at any inclination angle. In the case of multiple fulcrums to support huge equipment and heavy loads, the difficulty of leveling is obvious by manually lifting and lowering each fulcrum to make it level through the traditional observation level. Nearly 80% of the vehicle-mounted platforms in our country have not yet realized automatic level adjustment, and most of the equipment that realizes automatic level adjustment is electro-hydrau...
