Description

Removable nested type elevator

Technical field

The utility model relates to a kind of lifting goods and manned implement, refers to the vertical conveyor that goods transports between a kind of carrying that is applicable to the short range goods and the diff-H especially.

Background technology

Usually can be applied to dumbwaiter equipment in the production, as: exhibition is arranged exhibits and is torn exhibition open, and goods transports between the flow production line diff-H; The carrying of short range goods, parallel loading and unloading; Regulate workpiece height, the feeding of eminence feeder, the lifting of main equipment accessory during the workpiece assembling; Carrying vehicles such as storage loading and unloading place and fork truck are supporting to carry out that goods loads and unloads fast etc.Jacking equipment now commonly used has two kinds on fixed hydraulic elevator and movable type hydraulic elevator, as shown in Figure 1, the lifting arm of elevator is the connecting rod shape structure of reporting to the leadship after accomplishing a task, and hydraulic mandril provides power, control lifting, the vertical lift machinery that the telescopic sleeve oil cylinder is formed.The fixed hydraulic bay-lift is a kind of lifting good stability, is the ideal tools of the goods up and down in places such as workshop, market, storehouse.The movable type hydraulic elevator has two kinds of common structures, as shown in Figures 2 and 3, according to the superposed state after the lifting arm folding, can be divided into vertical telescopic and horizontal stretch formula, flexural deformation easily, can be widely used in the occasion of aloft work such as station, harbour, hall, hotel, workshop, this two form all has the shortcoming that volume after the folding is big, take up space, and connecting rod bonded assembly structural strength is little.

The utility model content

The purpose of this utility model is to provide a kind of removable nested type elevator, support load bearing stength height, in conjunction with firmly, flexible smooth, take up an area of little after the folding, easy operating, it is steady also to have a lifting, operates light, go slick, safe in utilization, the entire machine design compact conformation, rock little, in light weight, load-carrying is big, characteristics such as conveniently moving.

For achieving the above object, technical solution of the present utility model is:

Removable nested type elevator, comprise lifting arm, bearing platform structure and base, base has castor, also comprise the driven pulley group, described lifting arm is upright quadra structure, the interior exterior angle on lifting arm four limits itself is a guide rail, and several lifting arms are passed the lifting arm setting-in bearing platform structure that contracts nested, the most inboard; Described driven pulley group comprises fixed pulley, cable wire, change speed gear box.

The V-arrangement pulley is established at four angles, peripheral lifting arm top, and middle all lifting arms are all established the V-arrangement pulley up and down, and the lining is enclosed below the lifting arm four angles and established the V-arrangement pulley, V-type pulley and the corresponding sliding block joints of four limit guide rails.

Described quadra structure is rectangular frame structure, square-shaped frame shelf structure.

Also comprise control handle, described control handle links to each other with change speed gear box.

Also being included as the driven pulley group provides the electrical motor and the control button thereof of power.

Described driven pulley group also comprises reel and ratchet device.

Described driven pulley group also comprises service brake, and service brake is connected with the reel axis by cable wire.

Described castor is the cardan wheel of tight mechanism with lock.

Described bearing platform structure is to be replaceable bearing platform, comprises loading arm and bearing platform.

During use, change speed gear box reaches the purpose of carrying article by the lifting of cable traction control bearing platform.

After adopting such scheme, it is upright rectangular frame structure that the utility model has adopted lifting arm, by framed structure, and with extension load-carrying height, the support strength height, in conjunction with firmly, flexible smooth.The interior exterior angle on elevator machine frame four limits is a guide rail, several lifting arms pass contract nested, shrink the back take up an area of little, easy operating.Lifting arm four limit guide rails and be located at lifting arm V-arrangement pulley up and down and cooperate by assembly pulley and change speed gear box control, are realized the installation and the landing of differing heights object, reach the requirement of differing heights loading and operation, lifting is steady, operates light, go slick, safe in utilization.The entire machine design compact conformation, rock characteristics such as little, in light weight, conveniently moving, ascend a height, move job safety, economical and practical, reduce labour power and labour intensity.
