Description
Technical field
The present invention relates to crane accessory technical fields, specially a kind of crampon for building crane.
Background technology
Suspension hook is one is the shackle or hook with chain or rope, another hook that is coarse, usually having handle, espespecially
To transport goods or hang the most common type suspender in hoisting machinery that hooks of meat, suspension hook is often by means of member hangs such as pulley blocks
On the steel wire rope of lifting mechanism, suspension hook is divided into single hook and double hook by shape;It is divided into forging suspension hook and stacked by manufacturing method
Suspension hook, single hook is simple to manufacture, is easy to use, but stressing conditions are bad, and it is 80 tons of workplaces below to be used in lifting capacity mostly;
Frequently with the symmetrical double hook of stress when lifting capacity is big, the steel plate that stacked suspension hook is cut and formed by several pieces rivets, individual plates
Entire suspension hook will not destroy when material is cracked, and safety is preferable, but it is larger to conduct oneself with dignity, and be used in big elevating capacity or handling molten steel mostly
On the crane for containing bucket, suspension hook is often hit in operation process, must be manufactured using the Fine Steel Casting iron of good toughness, suspension hook classification
It is extremely wide, it generally comprises:Shackle, hanging ring, annulus, pyriform ring, long hanging ring, combination hanging ring, S hooks, nose suspension hook, American suspension hook goat's horn are hung
Hook, eye-shaped Slip Hook, with insurance card lifting bolt, chain shackle, have the characteristics that it is unique, novel, of fine quality, safe, be suitable for work
Factory, mine, oil, chemical industry and ship harbour etc., it is ensured that safety, quality safety coefficient, dead load reaches 3 times, with mechanical row
Industry develops, and general suspension hook cannot meet the lifting of big object, under the environment such as harbour, harbour, operation on the sea, the volume of suspension hook
Determine lifting capacity and reach a few kiloton or even ton up to ten thousand, therefore, suspension hook uses special substance with regard to extremely important when making, and forging is hung
Hook common material has 20DG20Mn, 35CrMo, DG34CrMo, 30Cr2Ni2Mo etc..
But there are following deficiencies for the prior art:
1, crampon using when stop features get rusty easily;
2, safety is bad when crane hook uses, and slings job insecurity.
Invention content
In view of the deficiencies of the prior art, it the present invention provides a kind of crampon for building crane, has solved
Weight suspension hook using when stop features get rusty easily used with crane hook when safety it is bad, sling asking for job insecurity
Topic.
To achieve the above object, the present invention provides the following technical solutions:
A kind of crampon for building crane, including fixed link, the fixed link are interspersed in the top of coupler body, institute
The lower section that fixed link is located at bindiny mechanism is stated, the upper end of the coupler body is mounted on the lower end of bindiny mechanism, bindiny mechanism's packet
Mounting blocks, link block, bearing and rotating seat are included, the link block is mounted on the lower end of mounting blocks, the both sides setting of the bearing
Above the junction of link block and mounting blocks, it is connected by way of clamping, the bearing is socketed in the middle part of rotating seat,
The rotating seat is T-type, and the down either side of rotating seat top high spot and the both sides upper end of bearing abut against, the coupler body
Opening limited position mechanism is installed, the position-limit mechanism includes connector, clockwork spring, baffle, block and axis pin, and the clockwork spring is logical
It crosses connector with the outer wall of coupler body to be connected, the clockwork spring is mounted at the center of axis pin, one end and the axis pin phase of the baffle
Connection, the block installation baffle and the outside junction in axis pin, the other end of the baffle and the left upper end of coupler body offset
It connects, reinforcing rod is installed below the coupler body.
Preferably, the coupler body is mounted on the lower end of rotating seat.
Preferably, the inside of the axis pin offers cavity, and lubricating oil, the both sides of the cavity are filled in the cavity
Offer oil outlet.
Preferably, through-hole is offered in the fixed link, the through-hole is provided with two groups, is opened in a left side for fixed link respectively
Right both ends, the through-hole are internally provided with auxiliary hangs muscle.
Preferably, the reinforcing rod is provided with four groups, is separately positioned on the lower end inside of coupler body, by welding with
Coupler body is connected.
The present invention provides a kind of crampons for building crane, have following advantageous effect:
(1) present invention is by the position-limit mechanism of setting, and position-limit mechanism includes connector, clockwork spring, baffle, block and axis pin,
Axis pin is internally provided with cavity, and the both sides of cavity offer oil outlet, in coupler body in use, needing rope being hooked on coupler body
On, dam forces are rotated down around clockwork spring, and after rope is hooked on coupler body, clockwork spring rebound can drive baffle to playback, and make
The lower end of baffle is connected to the left upper end of coupler body, the block of setting for limit baffle will not rotary motion outward, use
Convenient, when driving axis pin rotation, oil outlet can also slide on clockwork spring inner wall, when rotating moment, in cavity
Lubricating oil can be thrown out of axis pin is lubricated, to make baffle be less prone to stuck phenomenon, when usual, go out
Oilhole is connected on the inner wall of clockwork spring, and when not rotating, the lubricating oil in cavity is not easy to flow out Come, rotation when
It waits, can just be painted on the inner wall of clockwork spring, may be implemented to ask gap oiling, so as to achieve the purpose that saving, will not cause more
Remaining waste need not often go to fill lubricating oil to cavity, and in the dust of construction site, crampon is typically exposed to the external world,
Pass through the lubricating oil of setting so that baffle will not become rusty extremely on coupler body, and stop features are easy life when solving crampon use
The problem of rust.
(2) for the present invention by the bindiny mechanism of setting, bindiny mechanism includes mounting blocks, link block, bearing and rotating seat, hook
Body is mounted on the lower end of rotating seat, and artificial moves rotating seat, bearing movable so that coupler body rotates, and changes direction, coupler body it is upper
Side is equipped with fixed link, and fixed link assists the length of hangs muscle not by assisting hangs muscle to be connected with the crane large arm of top
Only it is merely a kind of, is made and changed according to on-site actual situations, coupler body usage time is long, but bindiny mechanism is replaced,
Bindiny mechanism is using a period of time, because oxidative phenomena occurs for dust or rainwater so that bindiny mechanism becomes fragile, by auxiliary
Hangs muscle is helped, coupler body is connected with the crane large arm of top, prevents bindiny mechanism from accident occurs and is broken, causes the wound of personnel
Evil, solves the problems, such as that safety is bad when crane hook use.
(3) reinforcing rod of the invention by setting, crampon sling object usually using rope, and rope hangs over coupler body
On, four groups of reinforcing rods of setting increase the frictional force of rope and coupler body so that rope will not be moved arbitrarily, sling work more
Stablize.
