Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the device of the present invention includes a curved plate 2 erected on the tractor body 1, and the curved plate 2 is fixed on the outside of the two central tie rods 5 on the tractor body 1 by the fixed plate 3 on the curved plate, the lower fixed plate 4 of the curved plate and bolts (Such as figure 2 shown). Such as image 3 As shown, the curved plate 2 is welded by two side plates and a transverse plate, and concentric through holes 6 and curved slots 7 are opened at corresponding positions on the two side plates.

[0021] Below the curve plate 2 is provided with a tractor suspension frame lower cross bar 8 connected on the tractor body 1 . The lower cross bar 8 swings with the end close to the tractor body as a fulcrum, and the side plate of the curved plate 2 is parallel to the swing surface of the lower c...

Abstract

The invention relates to a linear lifting device in swing process, which comprises a curve plate fixed on a tractor, a main swing arm, an upper sliding rod and a lower sliding rod; wherein, a concentric through hole and a curve slot hole are arranged on the curve plate; the head part of the main swing arm is connected with the concentric through hole of the curve plate, the middle part is connected with the lower transverse rod of a suspension frame through a main arm connecting plate, the tail part of the main swing arm is mounted with a guiding base, an upper linear slot hole and a lower liner slot hole in certain angle are machined on the main swing arm, and the two slot holes meet at the concentric through hole; the front end of the upper sliding rod pass through the curve slot hole and the upper linear slot hole through a connecting pin; the front end of the lower sliding rod pass through the curve slot hole and the lower linear slot hole through a connecting pin; the rear ends of the upper and lower sliding rods respectively pass through two guiding holes on the guiding base to connect with a connecting base, the lower sliding rod is connected with the base of the connecting base and the upper sliding rod is movably connected with the guiding rod of the connecting base. The linear lifting device realizes the purpose of linear lifting of the tractor trailer unit in the swing process.

Description

technical field [0001] The invention relates to a mechanical lifting device, in particular to a device configured with a large and medium-sized tractor during swinging in a straight line. Background technique [0002] At present, there are usually two ways of connecting tractors and rear implements at home and abroad, one is directly connected by traction, and the other is articulated through a hydraulic suspension device that can realize lifting movements. The connection between the hydraulic suspension and the rear implement is a three-point connection (the rear implement is connected with two lower connecting plates and an upper central tie rod on the hydraulic suspension). The hydraulic oil cylinder of the tractor pushes the lifting arm of the hydraulic suspension device, and the lifting arm pulls the vertical tie rod to move up and down. The vertical pull rod drives the two connecting plates to swing up and down at a certain point of the tractor, thereby realizing the ...
