Abstract

A double-stroke scissor frame mechanism comprises an upper platform, two left supporting arms, two right supporting arms, two hydraulic cylinders and a lower platform. The upper platform is arranged above the lower platform. Lower ends of the two right supporting arms are respectively hinged at two side portions of the surface of the left end of the lower platform. A front side portion and a back side portion of the upper end of each right supporting arm are respectively provided with idler wheels. Upper ends of two left supporting arms are respectively hinged on two side portions of the bottom face of the left end of the upper platform. Two side portions of the lower end of each left supporting arm are respectively provided with idler wheels. One left supporting arm is hinged with the middle of one right supporting arm. Bottom faces of cylinder bodies of the two hydraulic cylinders are respectively hinged on two sides of the middle of the surface of the lower platform. Outer ends of piston rods are respectively hinged on upper portions of the left supporting arms. In the working process of the double-stroke scissor frame mechanism, strokes of the hydraulic cylinders are increased along with increase of the hoisting height of the upper platform, and then are in returning motion along with the increase of the hoisting height of the upper platform after reaching certain height, and therefore the utilization rate of the hydraulic cylinders is high in the hoisting process, long in hoisting displacement, and high in stability.

Description

Two-pass type shear shank mechanism

Technical field

The utility model belongs to mechanical equipment technical field, particularly relates to a kind of two-pass type shear shank mechanism.

Background technology

Cut and rise mechanism and be applied in large quantities on the airport special equipments such as food conveyor, platform truck, mobile connecting bridge and portable control tower and other common apparatus.But at present commonly used cutting rises mechanism and have following point: the hydraulic actuating cylinder on it can only be done the one way motion, so the degree of utilization of hydraulic actuating cylinder is lower, and meeting and cause certain space to waste.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of doublestroke that has, and the hydraulic actuating cylinder degree of utilization is higher, take up room less, and the better two-pass type shear shank of safety performance mechanism.

In order to achieve the above object, the two-pass type shear shank mechanism that the utility model provides comprises upper mounting plate, two left support arms, two right support arms, two hydraulic actuating cylinders and lower platform; Wherein lower platform is horizontally disposed with; Upper mounting plate is arranged on the top of lower platform in the mode parallel with lower platform; The lower end of two right support arms is hinged on respectively the position, both sides, left end surface of lower platform, and before and after the upper end of every right support arm, the position, both sides is separately installed with a roller that can horizontally slip on upper mounting plate right-hand member bottom surface; The upper end of two left support arms is hinged on respectively the position, both sides, left end bottom surface of upper mounting plate, the position, both sides, lower end of every left support arm is separately installed with a roller that can horizontally slip on lower platform right-hand member surface, and a left support arm 2 and be positioned at the middle part of a right support arm of the same side with it hinged; The cylinder body bottom surface of two hydraulic actuating cylinders is hinged on respectively the both sides, middle part, surface of lower platform, and the piston rod outer end that is positioned at upper end is hinged on respectively the top of two left support arms, and cylinder interior is connected with hydraulic efficiency pressure system by pipeline.

Described left support arm and right support arm equal in length.

The two-pass type shear shank mechanism that the utility model provides in the course of the work, hydraulic cylinder travel on it first increases with the increase of upper mounting plate lift height, then to after certain altitude along with the return motion is done in the increase of upper mounting plate height, therefore in lifting process, the degree of utilization of hydraulic actuating cylinder is very high, the lifting displacement is long, and stability is high.In addition, this two-pass type shear shank mechanism also has structure design simply, rationally, and little, low cost and other advantages takes up room.

The accompanying drawing explanation

The two-pass type shear shank mechanism block diagram that Fig. 1 provides for the utility model.

The two-pass type shear shank longitudinal construction cutaway view that Fig. 2 provides for the utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the two-pass type shear shank mechanism that the utility model provides comprises the right support arm of the left support arm of upper mounting plate 1, two 2, two 4, two hydraulic actuating cylinders 3 and lower platforms 5; Wherein lower platform 5 is horizontally disposed with; Upper mounting plate 1 is arranged on the top of lower platform 5 in the mode parallel with lower platform 5; The lower end of two right support arms 4 is hinged on respectively the position, both sides, left end surface of lower platform 5, and before and after the upper end of every right support arm 4, the position, both sides is separately installed with a roller 6 that can horizontally slip on upper mounting plate 1 right-hand member bottom surface; The upper end of two left support arms 2 is hinged on respectively the position, both sides, left end bottom surface of upper mounting plate 1, the position, both sides, lower end of every left support arm 2 is separately installed with a roller 7 that can horizontally slip on lower platform 5 right-hand member surfaces, and a left support arm 2 and be positioned at the middle part of a right support arm 4 of the same side with it hinged; The cylinder body bottom surface of two hydraulic actuating cylinders 3 is hinged on respectively the both sides, middle part, surface of lower platform 5, and the piston rod outer end that is positioned at upper end is hinged on respectively the top of two left support arms 2, and cylinder interior is connected with hydraulic efficiency pressure system by pipeline.

Described left support arm 2 and right support arm 4 equal in length.

The two-pass type shear shank mechanism working process now the utility model provided is described below: at first will treat lifting such as food conveyor, platform truck, the airport special equipments such as mobile connecting bridge and portable control tower are placed on the upper mounting plate 1 of this two-pass type shear shank mechanism, then the hydraulic oil of self-hydraulic system passes into the bottom of hydraulic actuating cylinder 3 upper cylinder bodies by pipeline in the future, thereby make piston rod protruding, under the effect of piston rod, the roller 6 of the roller 7 of left support arm 2 lower ends and right support arm 4 upper ends will be respectively be moved to the left together with on the bottom surface of the surface of lower platform 5 and upper mounting plate 1, the left support arm 2 of result and right support arm 4 are drawn close gradually, thereby make upper mounting plate 1 and on the lifting thing for the treatment of raise gradually, reach thus the purpose of lifting object.
