Description
Technical field
It the utility model is related to a kind of new and high technology to rebuild traditional industry technical field, specifically a kind of bearing pin Anti-fall dress
Put.
Background technology
New high-tech industry is engaged in the research of one or more new and high technologies and products thereof, opened based on new and high technology
Enterprise's set of hair, production and technological service, often development difficulty is very big for the key technology that this industry is possessed, but once opens
Send out successfully, but have and be higher than in general economic benefit and social benefit.
Derrick crane needs to beat bearing pin in the air in dismounting, be when getting in the past using it is artificial single-handedly hold to prevent
Drop, but large-scale tower crane pin shaft is relatively large in diameter, diameter about 70mm, worker, which single-handedly holds, has larger difficulty, and
And worker acts power when also needing resistance to beat, if the accident of falling at high altitude will be occurred by coming off, potential safety hazard is larger.For this
Situation, to solve the difficulty in unloading process, spy researches and develops a kind of bearing pin anti-dropping apparatus.
Utility model content
The purpose of this utility model is to provide a kind of bearing pin anti-dropping apparatus, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：
A kind of bearing pin anti-dropping apparatus, including connection system, connection annulus, bearing pin sleeve, screw, bearing pin socket port,
The connection system includes rope, sling, big rope sling, and sling and big rope sling are arranged in the both ends of rope, sling respectively
On connection annulus, connection annulus is welded on the top of bearing pin sleeve, and bearing pin socket port is arranged on the bottom of bearing pin sleeve simultaneously
Hole slot is offered, screw passes through bearing pin socket port by the hole slot, and the part that screw stretches out bearing pin socket port is arranged with
Nut.
As further program of the utility model：The bearing pin sleeve is interference fitted with tower crane bearing pin.
As the utility model further scheme：The rope is steel wire rope.
As the utility model further scheme：The length of the rope is 2m.
As the utility model further scheme：The diameter of the big rope sling is more than the external diameter of bearing pin sleeve.
Compared with prior art, the beneficial effects of the utility model are：The utility model is reasonable in design, can effectively prevent
Shotpin axle drops, and avoids bearing pin the accident of falling at high altitude, has liberated the both hands of worker, needs worker to hold pin when reducing tower crane dismounting
The step of axle, save artificial, raising efficiency.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, a kind of bearing pin anti-dropping apparatus, including connection system 1, connection annulus 2, bearing pin sleeve 3, spiral shell
Silk 4, bearing pin socket port 5, the connection system 1 include rope 6, sling 7, big rope sling 8, and sling 7 and big rope sling 8 are distinguished
At the both ends of rope 6, sling 7 is set on connection annulus 2, and connection annulus 2 is welded on the top of bearing pin sleeve 3, pin sleeve
Cylinder port 5 is arranged on the bottom of bearing pin sleeve 3 and offers hole slot, and screw 4 passes through bearing pin socket port 5 by the hole slot,
The part that screw 4 stretches out bearing pin socket port 5 is arranged with nut.
Further, bearing pin sleeve 3 described in the utility model is interference fitted with tower crane bearing pin, makes bearing pin sleeve 3 and tower crane
Bearing pin connection is more firm.
Further, rope 6 described in the utility model is steel wire rope, wear-resistant, corrosion-resistant and strong with higher tension
Degree.
Further, the length of rope 6 described in the utility model is 2m, suitable for the tower body of various diameters.
Further, the diameter of big rope sling 8 described in the utility model is more than the external diameter of bearing pin sleeve 3, can allow entirely to fill
Put through.
Operation principle of the present utility model is：During using the utility model, bearing pin sleeve 3 is inserted in bearing pin, passes through screw 4
Bearing pin socket port 5 is tightened, with anti-dropout, bearing pin sleeve 3 is connected with stacker crane body using steel wire rope 6, made
Bearing pin can be hung from above on tower body when coming off, and rope sling 8 is connected with tower body, and whole device is passed through into rope sling 8 around tower body, so as to
It is bundled on tower body.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
