Abstract

The utility model discloses an anti-wind device for a rail-mounted crane trolley, belonging to the field of auxiliary devices of cranes. The anti-wind device is composed of an anti-wind pull rod, locating rings, anchoring rings, clamping rings and a fixed hook and characterized in that the anti-wind pull rod is a turnbuckle; the locating rings are welded at four corners of a frame of the trolley; the fixed hook is welded on the frame of the trolley; the anchoring rings are welded on a beam of a crane; the anti-wind pull rod is connected to the locating rings through the clamping rings. Compared with the prior art, the anti-wind device has the characteristics of simplicity and convenience in operation, safety and reliability and can be used for effectively preventing the trolley for sliding or rolling over and overturning under the condition of stress increment caused by typhoon.

Description

Locomotive crane tool dolly wind-proof device

Technical field

The utility model relates to a kind of elevator machinery auxiliary device, particularly a kind of wind-proof device that is applicable to locomotive crane tool dolly.

Background technology

Locomotive crane comprises crane in bridge type, transfer crane, seat type rotary crane etc.This kind machinery, also often berths near outdoor harbour when elevator machinery is in off working state generally in open area or wharf apron operation.For the large scale development trend that adapts to the shipping boats and ships and improve its handling efficiency, portal crane is also constantly towards the maximization future development, and the maximization of hoisting crane also makes its center of gravity improve, wind area increases, its wind load that bears is also just larger, especially for the coasting area of many typhoons, dolly on elevator machinery is easy to move under the wind-force effect and slides or turn on one's side, not only directly affect the production order of harbour, simultaneously also make relevant enterprise suffer great economic loss, even cause casualties.For guaranteeing safety, the windbreak anchoring device of monkey is essential.

All there is weak point in various degree in present existing windbreak anchoring device: 1. rail clamping device: although rail clamping device can make dolly directly be connected with track, and produce sliding resistance and certain ability that dolly is tumbled that prevents is arranged, but because of the contact surface of itself and track too little, be subjected to the impact of track seam dislocation, effect is undesirable, and complex structure, must could use by supporting Hydraulic Station, cost is higher, and the trend that is eliminated is gradually arranged.2. top rail machine: top rail machine can make dolly produce larger sliding resistance, better performances when being applied in Main Engine Cut-Off, but it is slow in one's movements, can't play windbreak function in trolley travelling and work.3. clip wheel device: install the clip wheel device additional on the walking passive gear of dolly, become the rolling of flower wheel for sliding, strengthen the friction drag that moves, can not be thoroughly that the dolly wedge is dead, and slow in one's movements, the motion of dolly in the time of can not effectively stoping prominent chance high wind in service.4. install anchoring device additional on the case beam, not only affect steel structure intensity, also can cause overhaul of the equipments inconvenience.5. anti-creep iron wedge, do not have protective action to the wind-force that makes progress.

Also have in prior art and use wind-proof pull rod or cable arrangement to carry out grappling, facts have proved, wind-proof pull rod or drag-line be also the strongest in the anti-hurricane of typhoon protection be also one of the device of most critical.But, due to installation deviation and in typhoon dolly have even deflection of larger vibration, often cause and stressedly between drag-line do not wait.Like this, stressed large drag-line may damage or rupture because of overload, and load is transferred on other drag-lines fully, causes drag-line to produce delivery type overload fracture, leads to grave accident.

The utility model content

Technical assignment of the present utility model is for above the deficiencies in the prior art, a kind of locomotive crane tool dolly wind-proof device of high efficient and reliable is provided, and can according to circumstances tightens up state to it and finely tune.

The technical scheme in the invention for solving the technical problem is: a kind of locomotive crane tool dolly wind-proof device comprises wind-proof pull rod, steady ring and anchor ring; It is characterized in that: also comprise snap ring and stay hook, described wind-proof pull rod is turnbuckle; Wind-proof pull rod is connected on steady ring by snap ring.

The track that above-mentioned anchor ring is welded on the crane balance beam is inboard.

Compared with prior art, the utlity model has following outstanding beneficial effect:

1, easy and simple to handle, safe and reliable, effectively prevent because causing dolly to slide in typhoon stress increase situation or turning on one's side and topple;

2, flower basket bolt in order to adjust windproof drag-line degree of tightness, keeps the optimum regime of windproof and skidproof.

Description of drawings

Fig. 1 is collapsed state schematic diagram of the present utility model.

Fig. 2 is working state schematic representation of the present utility model.

The specific embodiment

Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.

As shown in Figure 1, 2, the utility model comprises wind-proof pull rod 1, steady ring 2, anchor ring 4, snap ring 3, stay hook 5.Described wind-proof pull rod 1 is turnbuckle.Steady ring 2 is welded on 6 four jiaos of car frames, and stay hook 5 is welded in car frame 6, and anchor ring 4 is welded on crane transverse beam.Wind-proof pull rod 1 is connected on steady ring 2 by snap ring 3.

In prioritization scheme, anchor ring 4 is welded on track 7 inboards on the crane balance beam.

Fig. 1 is collapsed state schematic diagram of the present utility model, during hoisting crane work, wind-proof pull rod 1 is hung on stay hook 5 the dolly autonomous.

Fig. 2 is working state schematic representation of the present utility model.Hoisting crane fulfils assignment after work, and the staff is hooked on wind-proof pull rod 1 end on anchor ring 4, thereby the restriction dolly is along the displacement on the car body direction, in order to avoid produce slippage because of reasons such as typhoons.

Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the situation that do not deviate from various apparent change that spirit and scope of the present utility model carry out it all within protection domain of the present utility model.

Claims
