Description
Technical field
The utility model belongs to steel pipe's production equipment technical field, more particularly to a kind of to have the function of gantry of automatic spacing
Hoisting device of crane.
Background technology
Portal jib crane is the important equipment that must be provided in steel pipe's production.Previous portal jib crane, boom hoisting is upward
During rise, mainly manually range estimation manipulates lifting heights by rule of thumb, and when inevitably having improper maneuver, misoperation suspension hook will push up
Hit upper member；During operation, worker needs energy high concentration, manipulates tired.The boom hoisting of some portal jib cranes, using hanging
Hammer drives driving lever to be controlled, and when suspension hook rises, needs to collide sash weight and could control to automatically power off to stop rising, this method,
Suspension hook often collides sash weight, is easily damaged component, needs to be replaced frequently.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of it is simple in structure, make assembling easily,
Low manufacture cost, the portal jib crane with the automatic spacing lifting without often replacing component, labor intensity can be reduced
It puts.
The utility model solves its technical problem and is achieved through the following technical solutions：
A kind of portal jib crane boom hoisting with automatic spacing, including electric block, cucurbit walker, switch
Case, it is characterised in that：A limiter is further included, electric block is set on cucurbit walker and is controlled with switch-box and connected, limit
Position device is set to electric block side on cucurbit walker and controls connection with switch-box, and the limiter by stent, is approached and opened
Composition is closed, stent is installed on cucurbit walker, and limiter is set on stent front end apart from five centimetres of electric block.
Moreover, the stent is made of chassis, L-type upper frame, chassis is installed on cucurbit walker, and L-type upper frame is laterally solid
Loaded at the top of chassis.
Moreover, its cross section of the chassis is U-shaped.
Moreover, the L-type upper frame, is formed with adjustment hole thereon.
It the advantages of the utility model and has the beneficial effect that：
1. the utility model has the function of the portal jib crane boom hoisting of automatic spacing, simple in structure, make, assembling is held
Easily.
2. the utility model has the function of the portal jib crane boom hoisting of automatic spacing, chassis and L-type upper frame and bottom are set
Frame cross section is U-shaped, features simple structure, convenient for assembling.
3. the utility model has the function of the portal jib crane boom hoisting of automatic spacing, adjustment hole is formed on L-type upper frame,
The adjusting proximity position of the switch can be needed according to suspension hook lifting heights.
4. the utility model has the function of the portal jib crane boom hoisting of automatic spacing, scientific structure design is reasonable, has
Simple in structure, making assembling is easily, production cost is relatively low, need not often replace component, can reduce the advantages that labor intensity, is one
Kind has the function of the portal jib crane boom hoisting with automatic spacing of higher innovation.

Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is limited, it is impossible to which the scope of protection of the utility model is limited with this.
A kind of portal jib crane boom hoisting with automatic spacing, including electric block 3, cucurbit walker 1, switch
Case, innovation are：Further include a limiter 4.Electric block, which is set on cucurbit walker and is controlled with switch-box, to be connected
It connects, limiter is set to the one side that electric hoist suspension hook upgrades on cucurbit walker and is controlled with switch-box and connected.
Limiter is formed by stent 5, close to switch 6, and stent is installed on cucurbit walker, and limiter is set to stent
Upper front end is apart from five centimetres of electric block steel wire rope.2 five centimetres of steel wire rope of the limiter on electric block, you can ensure sense
Induction signal, and can avoid because of steel wire rope pendulum impact
Stent is made of chassis 8, L-type upper frame 7, and chassis is installed on cucurbit walker, and L-type upper frame is laterally installed in chassis
Top.Its cross section of chassis is U-shaped.L-type upper frame is formed with adjustment hole 9 thereon.
The operation principle of the utility model：
The portal jib crane boom hoisting that the utility model has the function of automatic spacing is assemblied on portal jib crane, according to steel
The position of maximum height steel wire rope that cord is raised above will approach switch and be set at the position steel wire rope, and make to approach switch
Front end is apart from about five centimetres of steel wire rope peak position.In operation process, when suspension hook rises, steel wire rope is wound on electric block
During to peak position, to signal and switch-box is transmitted a signal to close to inductive switching, the electric elements in switch-box are automatic
The power supply of control cut-out Motor Driven Elevating Calabash motor, electric block stop operating, you can realize control height under hook, limitation suspension hook
The purpose of position.
Although disclosing the embodiment and attached drawing of the utility model for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modification are all can
Can, therefore, the scope of the utility model is not limited to embodiment and attached drawing disclosure of that.
