Further describe the utility model in conjunction with the accompanying drawings, the utility model is made of chassis, column, coaster, lifting holder fork, turn-screw, power drive and the return pulley device that is used to move.One specific embodiment is provided shown in the accompanying drawing.By the body that chassis 1 and column 2 constitute, column 2 connects with chassis 1 usefulness bolt by the gusset piece 21 that is welded on its lower end, and the forebody on chassis 1 is a fork-shaped, about pitch 11,12 front ends and be provided with return pulley 13,14.Middle part, 1 rear end is provided with manpower traction's easy to loading and unloading towing dolly formula return pulley device on the chassis.This device is by including: wheel 91, wheel shaft 90, the supporting body 92 and the mop 94 that are fixedly connected on wheel shaft 90 constitute.One bearing pin 93 is arranged on the supporting body 92, be set with a connected body 15 at 1 rear end, chassis middle part, offer a pin-and-hole 16 on it, chassis connected body 15 is seated on the supporting body 92, bearing pin 93 and pin-and-hole 16 plug-in mountings are hinged to cooperate connection, when needs move this lifting machine, hold up 1 rear portion, chassis with towing dolly, mop 94 these machines of traction by towing dolly move.

A connected body 22 has been fixedly connected in the upper end of column 2, leading screw 4 is parallel to column 2, the upper end of leading screw 2 is rotated to install with connected body 22 by axle bed 41, surface bearing 42, radial bearing 44, bearing stopper nut 43 mechanism arrangement and is connected, and it suspends leading screw and is installed on the connected body 22.The lower end of leading screw 2 is installed with gusset piece 21 rotations on chassis or column 2 bottoms by axle bed 46 and is connected.The motor 7 that drives the leading screw rotation is fixedly mounted on the connected body 22.Driving leading screw 2 with sprocket wheel or gear drive rotates.

Coaster 3 is one to be slidingly installed with column 2, move up and down along column, carry the movable parts of lifting holder fork, it adopts the plate body welded structure, weld the car body of making coaster by the four sides plate body, bearing pin 31,33,

guide wheel

32,34 are installed on the coaster body,

guide wheel

32,34 movably is installed on the bearing pin 31,33, guide wheel depends on the front and rear surfaces of column 2, and coaster 3 is slidingly installed by bearing pin 31,33 and

guide wheel

32,34 and column 2.

The nut that cooperates drive coaster 3 to move up and down with leading screw 4 along column 2.It can be directly to be fixedly connected on coaster 3, also can adopt alternate manner to connect.Shown in Figure 1.Coaster 3 is provided with overhead gage 35.Side shield 36 has through hole 37 on the overhead gage 35, leading screw 4 passes this hole 37, and nut 5 places on the following leading screw 4 of baffle plate 35.Nut 5 is by seamed edge of himself or locating plate 51 and the limitting casing free-running fit that is made of side shield 36 and coaster body wall fixed thereon, and restriction nut 5 rotates.Between nut 5 and overhead gage 35, be provided with spherical pad 52,53.Nut 5 moves up and down along column 2 by overhead gage 35 drive coasters 3 with the transmission of leading screw 4.
