Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, an electric leveling support leg mainly includes a worm screw 1, a crank handle 2, a torque motor 3, a turbine 4, a first flat key 5, a transition shaft 6, a second flat key 7, a screw rod 8, a nut 9, Guide rod 10, the third flat key 11, outer sleeve 12, gear cover 13, proximity switch 14, spring 15, top cover 16.

[0027] The action principle is as follows: the rotation of the torque motor 3 directly drives the rotation of the worm 1, and the worm 1 further drives the rotation of the worm wheel 4, drives the transition shaft 6 to rotate through the first flat key 5, and then drives the screw 8 to rotate through the second flat key 7, and further pushes the nut 9 and guide rod 10 stretch out or retract.

[0028] The proximity switch 14 is arranged on the top cover 16, and the retaining cover 13 is fixedly connected with the ball scre...

Abstract

The invention relates to an electric leveling supporting leg which mainly comprises a worm, a crank, a torque motor, a turbine, a first flat key, a transition shaft, a second flat key, a ball screw, a ball nut, a guide rod, a third flat key, an outer sleeve, a check cover, a proximity switch, a spring and a top cover. The grounded detection problem of the electric leveling supporting leg is solved, the electric leveling supporting leg has the manual and electric operating modes, switching is not needed, and a transmission device has the self-locking function. The detection function of the leveling supporting leg is enhanced, the operating function of the supporting leg is improved, and the operating safety of the supporting leg under the loaded condition is effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicle electromechanical leveling, in particular to an electric leveling support leg. Background technique [0002] In many occasions, on-board mobile equipment needs to be automatically leveled before work, so that the work can be completed under an accurate horizontal reference. Usually, the car loaded with equipment is supported as a whole with four supporting legs, and then the automatic leveling is realized by an automatic control device. The role of the supporting legs is to bear the load of the vehicle, adjust the height of the support point, and keep the support position unchanged after the leveling is completed. [0003] According to different power sources, the leveling support legs are divided into manual support legs, electric support legs and hydraulic support legs. The manual support leg is leveled by manual operation, which has a low degree of automation and is difficult to operate, so i...
