Abstract
A lifting device for a middle trough automatic installation welding machine tool comprises a machine frame, a lifting platform and a power hydraulic cylinder horizontally installed at the bottom of the machine frame, the end portion of a piston rod of the power hydraulic cylinder is connected with a vertical plate, and two sides of the vertical plate are respectively connected with a steel cable. A steel cable A of the steel cables extends from the vertical plate to pass by a fixed pulley at the lower portion of the left end of the machine frame and goes upwards, and then passes by a fixed pulley at the upper portion of the left end of the machine frame and goes downwards to be connected with the left end of the lifting platform. The other steel cable B extends from the vertical plate to pass by a fixed pulley B at the lower portion of the left end of the machine frame, extends rightwards along the bottom of the machine frame, passes by a fixed pulley at the bottom of the right end of the machine frame, passes by a fixed pulley at the upper portion of the right end of the machine frame, and then extends downwards to be connected with the right end of the lifting platform. The lifting device for the middle trough automatic installation welding machine tool can achieve automatic lifting of the lifting platform of the middle trough and is matched with a space stepping down when the middle trough overturns. In addition, the lifting device adopts the matching of the horizontal hydraulic cylinder, the steel cables and the pulleys, achieves lifting of the lifting platform, can save the space at the lower portion of the machine frame, and provides larger moving range for the lifting platform.
Description
Technical field
The utility model relates to the technical field of the intermediate channel manufacturing of drag conveyor, particularly relates to a kind of lowering or hoisting gear that is used for intermediate channel automatic assembly welding lathe.
Background technology
The primary structure of various types of drag conveyors is identical with the parts of composition basically, and it mainly is made up of chain-drive section, middle part and three parts of drive end unit.
The operation principle of drag conveyor is, with the delivery chute that opens wide at the middle part bearing piece as coal, scraper plate is fixed on forms scraper chain on the chain, as driving component.After the head driving section starts, drive the sprocket wheel rotation on the head axle, make scraper chain circular flow drive coal and move, until arriving the chain-drive section unloading along delivery chute.Scraper chain is walked around sprocket wheel circular flow, accomplishes the conveying of coal.
The delivery chute of drag conveyor is formed by a plurality of intermediate channel butt joints, is the critical piece of drag conveyor.The intermediate channel of drag conveyor mainly comprises the ledge that is arranged at both sides and is fixedly connected on the middle plate between the two, wherein in plate mainly play a part to carry material, plate directly contacts with material and scraper chain in this.
Intermediate channel need be born the friction to it of coal, scraper plate and chain as the bearing part of material in the running, so intermediate channel is bigger as a kind of wearing detail demand; Existing intermediate channel all is to adopt artificial welding; The stability of its weldquality, speed of welding all can not guarantee, remain to be proposed a kind of automatic welding equipment; Because the total upset of the welding procedure of intermediate channel is inevitable technology; The stand of whole support intermediate channel just need be stepped down when upset, to intermediate channel upset vacating space, existing facilities fail head it off.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of lowering or hoisting gear that is used for intermediate channel automatic assembly welding lathe to be provided.
The technical scheme of the utility model is: a kind of lowering or hoisting gear that is used for intermediate channel automatic assembly welding lathe; Comprise frame, lifting platform; Lying low is installed in the power hydraulic cylinder of frame bottom, and the piston rod end of described power hydraulic cylinder is connected with a riser, and the both sides of this riser are connected with cable wire respectively; The fixed pulley A that one of them cable wire A begins to stretch out the bottom of walking around the frame left end by riser upwards, the fixed pulley of walking around frame left end top again is downwards and be connected the left end of lifting platform; After another one cable wire B began to stretch out the fixed pulley B that walks around frame left end bottom by riser, along frame bottom to the right and walk around the fixed pulley of frame right-hand member bottom, the fixed pulley of upwards walking around frame right-hand member top then downwards and be connected the right-hand member of lifting platform.
Described cable wire is connected on the riser through the adjustment bolt, and described adjustment bolt one end connects cable wire for hook, and the other end is the screw mandrel that passes riser, is equipped with nut on the screw mandrel of riser both sides.
Lifting platform comprises lifting platform body and parallel several intermediate channel carrying rollers mounted thereto.
The beneficial effect of the utility model
The lowering or hoisting gear that is used for intermediate channel automatic assembly welding lathe of this utility model can be realized the automatic lifting of the lifting platform of intermediate channel; Step down in space when cooperating the intermediate channel upset; This lowering or hoisting gear adopts the hydraulic cylinder and cable wire, the pulley that lie low to cooperate in addition; Realize the up-down of lifting platform, can save the space of frame lower, bigger scope of activities is provided to lifting platform.
