Abstract

The utility model relates to a light crane, comprising a column type support, an upper swing mechanism, a clamp plate type amplitude changing assembly, a telescopic working arm, a swing positioning device, and a steel rope hook which is driven by an electric hoisting mechanism. The utility model is characterized in that the crane can swing for 360 DEG, a working radius can be conveniently adjusted, and a power supply on a vehicle can be used. The utility model has the advantages of convenient operation, decreased labour intensity for loading and unloading, light weight, reduced power loss for vehicles, and decreased expense for operations. The utility model can be used for lifting on vehicles, and the work can be completed by a driver only. The utility model is especially suitable for being assembled on light lorry vehicles, is suitable for lifting heavy objects below 450 kg, and can also be used as a fixed crane.

Description

Light crane

The utility model relates to a kind of elevator machinery, and particularly a kind of light hoisting gear that adopts electric tramsmission is mainly used in light-duty vehicle truck-mounted crane dress weight.

Elevator machinery is the lifting device that often uses of carrier particularly in modernization construction.The lorry-mounted crane tool is used very extensive.The lorry-mounted crane tool is generally hydrostatic drive at present, cost is higher, in addition, existing hydraulic pressure truck-mounted crane relate to vehicle retrofitting, and formality is loaded down with trivial details, the complete machine structure complexity, volume is big, has increased the automobile unnecessary power loss, and common product mostly is the large-tonnage design, lifting to little tonnage article seems heavy and inconvenient, can not satisfy the needs of handling labor.

In view of this, the purpose of this utility model is to provide a kind of light hoisting gear that adopts the drive of motor elevator, and it is specially adapted to the truck-mounted crane dress to little tonnage article, has overcome the deficiency of prior art.

The purpose of this utility model is to realize like this.The support of light hoisting gear is the column form, and swing type mechanism is fixed on above the column, is plate-like, the two is rotating, and is fixed with the luffing assembly on swing type mechanism, and the inner of basic arm is fixed in the luffing assembly, adopt rotation-coupled, and being provided with the registration device of regulating the basic arm angle, hoisting mechanism is a driven by motor, is packed in luffing assembly side, basic arm is a tubular, in telescopic boom is arranged and is provided with registration device, there is suspension hook on the telescopic boom top, links through steel cable and hoisting mechanism.

The obtained technological advance of the utility model is: (1) this crane structure is simple, in light weight, has only 100kg, biggest lifting capacity 450kg, (2) demolition part is less, needn't often keep in repair, (2) but can turn round luffing, scalable, superior performance, (4) this machine AC and DC is dual-purpose, can use loaded power, easy to use, (5) applicability is strong, both has been suitable for town and country, be suitable for woods again and herd, (6) are simple to operate, safe, reliable.

The embodiment that provides below in conjunction with accompanying drawing and accompanying drawing further describes the utility model.

Should illustrate that present embodiment is not as to qualification of the present utility model.

What Fig. 1 provided is structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is that the B of Fig. 1 is to view (semi-sictional view)

Fig. 4 is a basic arm luffing view.

With reference to the utility model shown in Figure 1, this machine support 12 is packed on the truck body base plate 14, and support 12 is the column form, there is garden type attic base the column upper end, swing type mechanism 10 is packed on the attic base, and swing type mechanism is the garden disk shape, and passes through the bearing normal-running fit between column; Bolster is arranged above the swing type mechanism, and between the swing type mechanism assembly ball is arranged, rotate flexibly, attic base is installed in the rotating shaft, vertically be provided with two iron plates 16 on the attic base, (Fig. 3) claim vertical clamping plate, it is shown in Figure 1 that second splint has constituted luffing assembly 6() a part, have knock hole on the clamping plate base, on the disk cover of swing type mechanism, be provided with the hole seat, the two can insert revolution locating dowel pin 18(as shown in Figure 3), in order to limiting rotary position, the limit of keeping right, clamping plate 16 both sides of luffing assembly has luffing knock hole 8, basic arm 4 is a tubular, its the inner and connects normal-running fit with the clamping plate axle between two clamping plate, clamping plate are provided with luffing locating dowel pin 7, it is inserted in the luffing knock hole on the clamping plate, can limit the extension angle of basic arm, adjusting position can reach by a plurality of knock holees are set, and telescopic boom 2 is arranged in the basic arm 4, it also is empty tubular, all have knock hole 1 on two arms, the position of knock hole can be preset by the difference requirement, and two arm rest telescopic boom locating dowel pins 3 are fixing.For fixation, can also insert snap ring and can guarantee safety in the punching of the locating dowel pin other end, more firm, in case the bearing pin slippage.As shown in fig. 1, the top of telescopic boom 2 is provided with suspension hook 19, it links to each other with the hoisting mechanism 9 that is packed in luffing assembly clamping plate side through steel cable, as shown in Figure 3, what the cable hoist structure was selected for use is that Light-duty Vehicle is with being close to magneto generator 17 and epicyclic reduction gear unit 15, drive motor-driven cylinder elevator steel cable 5 by automobile power source through being reverse into the 220V source of AC, mention suspension hook 19, the operating switch 11 that links to each other with motor can be pulled in the automobile with flexible cord, operate more convenient, in use, can be with 13 of removable bearing sets of bearing in ground, the time spent can not turned up it or pull down.

Shown in Fig. 1 C, the C ' is the different fixing position of telescopic boom 2, and shown in D, the D ' is that the different luffings position of telescopic boom or the difference that is called basic arm are upheld angle, and shown in the M position is the retracted state of basic arm.

This hoisting crane should be installed in the front left side in the big railway carriage or compartment of automobile by designing requirement, is positioned at the automotive frame Ministry of worker, should note being carried out in accordance with regulations lubricated during use.Can adjust telescopic boom according to the distance of lifted weight object distance car, swinging radius generally in 1.3-1.8 rice scope, can be adjusted change angle according to cargo weight, and the lifted weight thing should be in allowed band.
