Abstract
The invention provides an upper pressing type shear shank mechanism which comprises an upper platform, two left supporting arms, two right supporting arms, two hydraulic cylinders and a lower platform, wherein the lower platform is arranged above the lower platform; the lower ends of the two right supporting arms are respectively hinged to two sides on the surface at the left end of the lower platform; idler wheels are arranged on the front side and the rear side at the upper end of each right supporting arm; the upper ends of the two left supporting arms are hinged to two sides on the bottom surface at the left end of the upper platform; the idler wheels are arranged on two sides at the lower end of each left supporting arm; one left supporting arm is integrally hinged to the middle of one right supporting arm; the bottom surfaces of two hydraulic cylinder bodies are respectively hinged to the upper parts of the two right supporting arms; and the external ends of piston rods are respectively hinged to the two sides in the middle of the bottom surface of the upper platform. According to the upper pressing type shear shank mechanism provided by the invention, the hydraulic cylinders are configured at the upper parts of the right supporting arms, therefore, the hydraulic cylinders are short in route; and moreover, the routes of the hydraulic cylinders are increased along with the raise of the hoisting height of the upper platform during hoisting, and the hydraulic cylinders are returned when the height of the upper platform is increased after reaching a certain height, so that high utilization rate of the hydraulic cylinders can be achieved.
Description
Technical field
The invention belongs to mechanical equipment technical field, particularly relate to a kind of pressure type shear shank mechanism of going up.
Background technology
Cut and rise mechanism and be applied at food conveyor, platform truck in large quantities, move on airport special equipment such as 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 hydraulic actuating cylinder degree of utilization is lower, and meeting and cause certain space waste.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of doublestroke that has, the hydraulic actuating cylinder degree of utilization is higher, and it is littler to take up room, and safety performance is better gone up pressure type shear shank mechanism.
In order to achieve the above object, the pressure type shear shank mechanism of going up provided by the invention 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 with the mode parallel with lower platform; The lower end of two right support arms is hinged on the position, both sides, left end surface of lower platform respectively, and the position, both sides is separately installed with a roller that can on upper mounting plate right-hand member bottom surface, horizontally slip before and after the upper end of every right support arm; The upper end of two left support arms is hinged on the position, both sides, left end bottom surface of upper mounting plate respectively; The position, both sides, lower end of every left support arm is separately installed with a roller that can on lower platform right-hand member surface, horizontally slip, and left support arm 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 the top of two right support arms respectively, and the piston rod outer end that is positioned at the upper end is hinged on the both sides, middle part, bottom surface of upper mounting plate respectively, and cylinder interior links to each other with hydraulic efficiency pressure system through pipeline.
The equal in length of described left support arm and right support arm.
The pressure type shear shank mechanism of going up provided by the invention is configured in right support arm top with the hydraulic actuating cylinder as the lifting engine installation, and promptly near the upper mounting plate place, so the stroke of hydraulic actuating cylinder is short.In addition, in the lifting process, hydraulic cylinder travel increases with the lift height of upper mounting plate earlier, do return and move along with the height of upper mounting plate increases hydraulic actuating cylinder behind the certain altitude then, so the degree of utilization of hydraulic actuating cylinder is very high.In addition, pressure type shear shank mechanism also has structure design simply, rationally on the basis, and little, low cost and other advantages takes up room.
Description of drawings
Fig. 1 is the pressure type shear shank mechanism block diagram of going up provided by the invention.
Fig. 2 is the pressure type shear shank structure longitudinal sectional view of going up provided by the invention.
The specific embodiment
Like Fig. 1, shown in Figure 2, the pressure type shear shank mechanism of going up provided by the invention comprises the right support arm of the left support arm of upper mounting plate 1, two 2, two 3, two hydraulic actuating cylinders 4 and lower platforms 5; Wherein lower platform 5 is horizontally disposed with; Upper mounting plate 1 is to be arranged on the top of lower platform 5 with lower platform 5 parallel modes; The lower end of two right support arms 3 is hinged on the position, both sides, left end surface of lower platform 5 respectively, and the position, both sides is separately installed with a roller 6 that can on upper mounting plate 1 right-hand member bottom surface, horizontally slip before and after the upper end of every right support arm 3; The upper end of two left support arms 2 is hinged on the position, both sides, left end bottom surface of upper mounting plate 1 respectively; The position, both sides, lower end of every left support arm 2 is separately installed with a roller 7 that can on lower platform 5 right-hand member surfaces, horizontally slip, and left support arm 2 and be positioned at the middle part of a right support arm 3 of the same side with it hinged; The cylinder body bottom surface of two hydraulic actuating cylinders 4 is hinged on the top of two right support arms 3 respectively, and the piston rod outer end that is positioned at the upper end is hinged on the both sides, middle part, bottom surface of upper mounting plate 1 respectively, and cylinder interior links to each other with hydraulic efficiency pressure system through pipeline.
The equal in length of described left support arm 2 and right support arm 3.
The pressure type shear shank mechanism working process of going up provided by the invention is set forth as follows: at first will treat being placed on the upper mounting plate 1 of pressure type shear shank mechanism on this of lifting such as airport special equipments such as food conveyor, platform truck, mobile connecting bridge and portable control towers at present; The hydraulic oil of self-hydraulic system passes through the bottom that pipeline feeds hydraulic actuating cylinder 4 upper cylinder bodies in the future then; Thereby make piston rod protruding; Under the effect of piston rod; The roller 7 of support arm 2 lower ends, a left side and the roller 6 of right support arm 3 upper ends will be respectively be moved to the left on the bottom surface of the surface of lower platform 5 and upper mounting plate 1 together; Result left side support arm 2 is drawn close with right support arm 3 gradually, thus make upper mounting plate 1 and on the lifting thing of treating raise gradually, reach the purpose of lifting object thus.
