The lifting supporting platform comprises a bed plate and a jacking base plate. The lifting supporting platform is characterized by further comprising a scissor jack arranged between the bed plate and the jacking base plate; four arms of the scissor jack are made from support plates to form a rhombus lifting frame, wherein two force application screw rods are arranged in the middle of the lifting frame, and the positions, at the force application ends of the two screw rods, of screw rod bodies are respectively provided with a transmission gear; the two transmission gears are in transmission through a chain; a force application handle is arranged at the force application end of one of the force application screw rods. The lifting supporting platform is reasonable in structure, easy and convenient to operate, and capable of being widely applied to all kinds of lifting operation.
Description
Technical field
The utility model relates to a kind of falling unit, specifically refers to a kind of landing support platform.
Background technology
Adopt at present jack very general as playing falling unit, such as monomer liquid pressure type jack, scissor-like jack etc., during use, the push rod of jack being butted on to the below of being played falling unit will be risen by ejection device or land, but in use find, when by ejection device, being a mobiles, the monomer jack is difficult to install steadily hold.The Mechanical Help industry of take is example, when at the larger part of some weight such as dismounting driving engine etc., jack need to be placed on to split part below, by after the dismounting of the bolt of rear end plate of part, because the mandril of lifting jack diameter is less, is difficult to split part is steadily held.In use procedure, also attempt using two jacks, below split part, place supporting plate, two jacks are placed on to the supporting plate below, after the part dismounting, two jack pressure releases are fallen after rise, part is held unlikely inclination by supporting plate and is come off.But use two jacks to need jack in jack-up and falling process, to keep the conformability of operation, cause equally supporting plate to tilt and cause part to come off otherwise two push rod height are inconsistent.
Summary of the invention
While for overcoming current use jack, carrying out the part dismounting, split part is difficult for the technical matters of steadily being held, and the utility model provides a kind of landing support platform rational in infrastructure, easy and simple to handle.
The technical solution adopted in the utility model is: a kind of landing support platform, comprise bed plate and jack-up seat board, it is characterized in that: this support platform also comprises the scissor-like jack be arranged between bed plate and jack-up seat board, described scissor-like jack comprises two upper backup pads in left and right, two lower supporting plates in left and right, the both sides at upper and lower support plate two ends are respectively to one articulated joint of Supporting plate extension, the articulated joint of both sides, stay bearing plate top, upper left, the articulated joint of both sides, stay bearing plate top, upper right is hinged with the two side of jack-up seat board respectively by two top jointed shafts, the articulated joint of both sides, stay bearing plate bottom, lower-left, the articulated joint of both sides, stay bearing plate bottom, bottom right is hinged with the bed plate two side respectively by two root bottom part jointed shafts, upper left stay bearing plate bottom articulated joint and lower-left stay bearing plate top articulated joint, upper right stay bearing plate bottom articulated joint and bottom right stay bearing plate top articulated joint are hinged respectively by the middle jointed shaft in two of left and right, left and right upper backup pad and left and right lower supporting plate form the rhombus alighting gear, two application of force leading screws pass respectively the middle jointed shaft in two of left and right, are respectively equipped with transmission gear on the leading screw body of two rhizoid thick stick force sides, and between two transmission gears, by chain gear, the force side of an application of force leading screw is provided with application of force handle therein.
The articulated joint on upper backup pad top, described left and right, the articulated joint of lower supporting plate bottom, left and right are dentation, and the articulated joint of left and right upper backup pad top articulated joint, lower supporting plate bottom, left and right is respectively by the mutual interlock of a tooth in articulated joint.
The width of described left and right upper backup pad, left and right lower supporting plate is less than the width of bed plate and jack-up seat board.
The beneficial effects of the utility model are: this landing support platform adopts stay bearing plate to make the payload area that can effectively increase the jack-up seat board alighting gear of scissor-like jack, by the jack distortion caused is set when the technological means such as two application of force leading screws, the interlock of hinged head's tooth can prevent that load is excessive, cause the appearance of jack-up seat board tilt phenomenon, in leading screw, introduce synchronous rotation device and can guarantee the steady lifting of jack-up seat board.This landing support platform of this landing support platform is rational in infrastructure, easy and simple to handle, can be widely used in various landing operations.
