Abstract

The invention relates to an electric support leg which comprises a support leg body as well as a gearbox and a motor arranged at the side part of one support leg assembly, wherein a main output shaft, a three-stage gear, a high-speed transmission gear, a low-speed transmission gear, an input bevel gear set, a shifting rod mechanism and a rocker plate are arranged inside a gearbox; the main output shaft is sleeved with the three-stage gear; the main output shaft is connected with a main gear transmission mechanism inside a left support leg assembly and a right support leg assembly; the input bevel gear set is driven by the motor; the high-speed transmission gear and the low-speed transmission gear are arranged on the rocker plate and are meshed with the input bevel gear set; the shifting rod mechanism is used for controlling the rocker plate to swing in three different shifts, so as to enable the three-stage gear to be meshed with the high-speed transmission gear, meshed with the low-speed transmission gear or dissociated from both the high-speed transmission gear and the low-speed transmission gear. The electric support leg has three options of manual control, electric high speed control and electric low speed control, and is reasonable in structure and labor-saving in operation.

Description

technical field [0001] The invention relates to the technical field of semi-trailer outriggers, in particular to electric outriggers. Background technique [0002] Semi-trailer outriggers are special parts for various semi-trailers. The left and right outriggers are installed on the left and right sides of the front end of the semi-trailer. When the semi-trailer is hooked to the tractor, the semi-trailer outriggers rise from the ground. At this time, the outriggers of the semi-trailer are extended to an appropriate length to keep the semi-trailer body level. Most of the adjustment of the inner casing of the existing legs is achieved manually, such as the semi-trailer supporting device disclosed in Chinese Patent No. 99236524.4 on June 28, 2000, including left and right legs that can be installed on the front end of the semi-trailer And its intermediate connecting shaft, two-speed gear transmission mechanism, the legs are closed inner and outer double casing structure; Sphe...
