Embodiment 1

[0047] refer to figure 1 , shows a flowchart of steps of a method for leveling a support platform according to Embodiment 1 of the present invention.

[0048] The leveling method in this embodiment is suitable for leveling a large-span four-point support platform, and the specific steps of leveling include:

[0049] Step S102: controlling the extension of the four outriggers, and determining that the pressure on the four outriggers reaches a first set threshold according to the triggering states of the pressure relays respectively corresponding to the four outriggers.

[0050] Among them, the four-point support platform is a platform supported by four outriggers, so-called large-span support platform. Those skilled in the art usually refer to a support platform with a length of more than ten meters as a large-span support platform. Then, the large-span four-point support platform in this embodiment refers to a support platform supported by four outriggers with a length of mor...

Embodiment 2

[0061] refer to Figure 4 , shows a flow chart of steps of a method for leveling a support platform according to Embodiment 2 of the present invention.

[0062] The leveling method of this embodiment is still applicable to the leveling of the large-span four-point support platform. The installation positions of the front and rear launch platforms on the vehicle body support platform are the same as those in the first embodiment. , More specifically, the first two-axis leveling sensor is arranged on the turntable of the front launching platform, and the second two-axis leveling sensor is arranged on the turntable of the rear launching platform.

[0063] The leveling of the supporting platform of the present embodiment specifically includes the following steps:

[0064] Step S202: The leveling module controls the extension of the four outriggers, and judges whether the pressure relays corresponding to the four outriggers are all triggered; if the pressure relays corresponding t...

Embodiment 3

[0100] refer to Figure 5 , shows a flow chart of the steps of a method for leveling a support platform in Embodiment 3 of the present invention, referring to Figure 6 A hardware schematic diagram of a leveling module implementing the leveling method in this embodiment is shown.

[0101] The support platform in this embodiment is a large-span dual-target four-point support platform, and the connection structure between the launch platform and the vehicle body is still as follows: image 3As shown, there are four outriggers, and the front and rear launch platforms are two leveling targets respectively. A dual-axis leveling sensor is installed on each of the two leveling targets. The dual-axis leveling sensor needs to be installed in a position that can truly reflect the The position of the final horizontal angle of the corresponding launch platform, for example: installed on the turntable of the launch platform.

[0102] like Figure 6 As shown, the leveling module, that is...

Abstract

The invention provides a leveling method and a leveling device for a supporting platform. The leveling method is used for a large-span four-point supporting platform and comprises the steps of controlling four supporting legs to extend out, and determining that the pressure on the four supporting legs reaches a first set threshold value according to triggering states of pressure relays respectively corresponding to the four supporting legs; adjusting the transverse angle and the longitudinal angle of a front emission platform and the transverse angle of a rear emission platform according to a set rule to enable the transverse angle and the longitudinal angle, which are sensed by a first dual-axial leveling sensor, of the front emission platform to be smaller than a second set threshold value and enable the transverse angle, which is sensed by a second dual-axial leveling sensor, of the rear emission platform to be smaller than a third set threshold value; respectively adjusting the heights of the supporting legs according to a set sequence, and changing the transverse angles of the front emission platform and the rear emission platform at preset angles according to the heights of the adjusted supporting legs. According to the leveling method and the leveling device, the platform can be effectively adjusted and horizontally and stably retained.

Description

technical field [0001] The invention relates to the technical field of support platforms, in particular to a method and device for leveling a support platform. Background technique [0002] In order to meet the needs of special fields such as the military, it is currently necessary to install a launch platform on the vehicle body to realize the installation of large weapons on the vehicle body. The structural diagram of the car body with the launch platform installed is as follows: figure 1 As shown, among them, the leveling platform of the car body, that is, the support platform, is a large-span support platform with a length of 12 meters. The whole platform is supported by four legs, and the four legs are respectively distributed in the middle and rear of the car body. The outriggers are distributed in a trapezoidal shape, and two launch platforms are arranged on the vehicle body platform behind the front two outriggers and the rear two outriggers respectively. [0003] ...
