Abstract
The utility model discloses a portable device enabling a crane to be multi-purpose, which can enable an automobile crane to have effects of a ladder truck, a high-altitude rescue vehicle and the like. The device can be articulated to the front end of a lifting arm of the crane, and a safe platform is provided for the operation of high-altitude operation, rescue and the like, and the device is simple in structure, is convenient to carry, and is installed rapidly; the device mainly comprises a load bearing frame (barrel), a shaft, a connecting pin, a lock nut, a spacing plate, an ejection rod and a bearing; the connecting pin in the device is inserted into a connecting pin hole in the side wall surface at the front end of the lifting arm of the crane and is positioned by the nut, thus the device can be used; the device after installation can be safely and firmly fixed on the lifting arm through the shaft, the connecting pin, the lock nut, the spacing plate and the like, and meanwhile, the device is convenient to dismount and mount; a sliding sleeve on the load bearing frame can rotate around the shaft, and the sliding sleeve, the ejection rod, the bearing and the other structures can enable the angle of the load bearing frame to be regulated automatically and timely when the elevation angle of the lifting arm changes. The device is excellent in performance, is wide in application field, and is wide in prospect.
Description
Technical field
The utility model can make car hosit have effects such as ladder truck, high-altitude rescue vehicle simultaneously through installing easy device additional.
Background technology
At present, car hosit is widely used in places such as factory, mine, oil field, harbour, urban construction field, emergency reliefs, and these workplaces usually need the staff to carry out aloft work.Because hoisting crane itself does not possess the effect that high-altitude operation platform is provided, and carries out aloft work to the staff and brings greater inconvenience.Present stage, the difficult problem of aloft work is mainly solved through purchasing ladder truck equipment in these places.Use not only cost height of hoisting crane, ladder truck yet purchase simultaneously, also have problems such as the parking place demand is big.Adopt this novel portable unit, can car hosit be had simultaneously the effect of ladder truck, high-altitude rescue vehicle.
Summary of the invention
In order to overcome existing hoisting crane the deficiency of high-altitude operation platform can not be provided; The utility model provides a kind of portable unit; This device can be hinged to the crane arm front end, for work such as aloft work, rescue provide a security platform, and simple in structure, easy to carry, quick for installation.
The utility model solves the technical scheme that its technical matters adopted: device mainly is made up of load-carrying basket (or well-bucket), rotating shaft and connecting pin, locknut, positioning plate, push rod and bearing.For hoisting crane with auxiliary cargo boom, capable of using insert the connecting pin that connects main crane arm and auxiliary cargo boom be connected the hinge-point of pin-and-hole as this device and hoisting crane.Do not have the hoisting crane of this connection pin-and-hole for other, can be at crane boom front end welding analog structure as hinge-point.The load-carrying basket can be welded by materials such as shaped steel, band irons, and lays base plate.The load-carrying basket also can be substituted by the suitable capacity can of other high strength.Be positioned at of the position perforate (bore dia according to material therefor intensity get 40mm-80mm suitable size) of center line vertical shaped steel in load-carrying basket side, and in the hole, welding the steel pipe of same outer diameter as, constituting the sliding sleeve that can rotate around the axis near upper surface.The high strength round steel that adopts two sections external diameters to be slightly smaller than bore dia is welded into T-shaped makes it become the part that has rotating shaft and connecting pin function simultaneously.Axle is inserted in the sliding sleeve, and the welding axle cap.The other end of axle installs spacing steel plate additional.At the parallel welding push rod of the vertical lower of axle sleeve and install the bearing that horizontally rotates additional and carry out further spacing and balance.With the cutting thread of connecting pin end, and be equipped with locknut.Can install cushion etc. additional at load-carrying frame bottom plate middle part in addition, the load-carrying basket is installed side door, makes things convenient for aloft work personnel work, and makes its convenient rescue in the rescue place.After this portable unit completes, with positioning and to use in the insertion of the connecting pin in the device connection pin-and-hole and with jam nut.Pivot structure can make this device have the automatically regulating horizontal force under positioning plate, push rod and bearing auxiliary.The aloft work personnel get into behind the load-carrying case just and can carry out operation with the high-altitude that crane boom arrives need of work.
The beneficial effect of the utility model is: make car hosit after installing this portable unit additional, have ladder truck, high-altitude rescue vehicle effect simultaneously, increase work efficiency, practice thrift cost greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

The specific embodiment
As shown in Figure 1 in the portable unit core, this device is installed on the connecting pin pin-and-hole position (shown among Fig. 1 8) on the car hosit crane arm front end side wall (position is shown among Fig. 4 6).Structures such as rotating shaft and connecting pin, locknut, positioning plate can be with this device after installation, is bonded on the crane arm to stability and safety easy disassembly simultaneously.Sliding sleeve can rotate around the axis, and when structures such as sliding sleeve, push rod, bearing made the load-carrying basket change at the crane arm elevation angle, it is vertical that in time automatic compensation load-carrying basket keeps direction.The hoisting crane characteristic has determined plane, crane arm left and right sides wall place to become vertical direction, so structure by gravitys such as sliding sleeve, push rod, bearing can keep direction vertical the load-carrying basket.Bearing plays the effect of rolling and supporting in this device, can prevent to cause danger when the axle sleeve rotational angle is excessive.
In the embodiment of Fig. 4, the load-carrying basket adopts framed structure, and base plate is laid in the bottom, and base plate is laid cushion near the side wall surface place.The load-carrying basket also is provided with side door, conveniently carries out height rescue.This device can supply two staff to carry out aloft work simultaneously.The load-carrying basket of this portable unit can be substituted by other suitable capacity high duty metal container.For the hoisting crane that itself does not have auxiliary cargo boom and main crane arm connecting pin pin-and-hole, can be at crane arm front wall welding connection pin-and-hole as depicted in figs. 1 and 2.The connecting pin of this portable unit is inserted in the connection pin-and-hole, with using after the jam nut locking.
