Abstract
The utility model relates to a pneumatic balance crane which belongs to hoisting and carrying machinery technical field. The pneumatic balance crane comprises a coiling block arranged in a shell body and a cable rope coiled on the coiling block, wherein an thread is machined on the inner hole of the coiling block and constructs a screw pair with a screw rod on the shell body; one end of the coiling block is restrained with a piston shaft axially, the piston is positioned in a piston cavity in the shell body. As the pneumatic balance crane adopts pneumatic drive, the pneumatic balance crane is easy and flexible to use and realizes accurate positioning; meanwhile, the pneumatic balance crane has convenient operation and good buffering performance.
Description
Technical field
The utility model relates to a kind of lifting appliance, and especially a kind of air counterbalance hangs, and belongs to lifting, handling machinery technical field.
Background technology
Understand according to the applicant, traditional winding type lifting appliance mainly is made of the drive motor that is placed in reel in the housing, is wrapped in the cable on the reel and drives reel usually.This type of lifting appliance is difficult to realize accurate location, and when lifting is convenient, dexterous inadequately, is easy to generate braking and impacts.
The utility model content
The purpose of this utility model is: at the shortcoming of above-mentioned existing existence, propose a kind ofly can realize accurate location, and lifting is convenient, dexterous air counterbalance hangs
In order to reach above purpose, air counterbalance bull ladle of the present utility model is drawn together and is placed in the interior reel of housing, is wrapped in the cable on the reel, and it is characterized in that: the endoporus of described reel is shaped on screw thread, constitutes screw pair with the screw mandrel that is supported on the housing; One end of described reel and piston axial constraint, described piston is arranged in the plunger shaft of housing.
Like this, after plunger shaft feeds pressurized air, will order about piston and drive longitudinal travel of reel, one side is the wire winding rod rotation under the effect of screw pair, thereby cable is wound up, and realizes the lifting of weight.
Understand easily,, therefore be easy to flexible control, realize accurately location because the utility model has been taked pneumatic actuation, and easy to operate, have good cushion characteristic.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Embodiment one
The basic structure of present embodiment air counterbalance device as depicted in figs. 1 and 2, housing (assembly) 20 is made of cylindrical shell and the protecgulum 5 and the bonnet 27 that are separately fixed at the cylindrical shell two ends, wherein be mounted with reel 12, by the hook seat 15 of captive joint with it hook 14 be housed on it.Be wound with steel wire cable 38 on the reel 12, the lower end of steel wire cable 38 connects suspension hook 43 down.The two ends of housing 20 are respectively by protecgulum center bolt 1 and bonnet center bolt 28 back-up roller ballscrews 10.The endoporus of reel 12 is shaped on screw thread, constitutes screw pair with ball screw 10.One end of reel 12 and piston 22 axial constraints, between plain thrust bearing 21 is housed.Piston 22 is arranged in the plunger shaft of housing 20.Other related components among Fig. 1 and Fig. 2 is respectively: drg 6, radial bearing 7, pin 11, housing inner covering 13, ball screw support sleeve 24, steel wire cable guide 31, pneumatic distribution valve 34, elbow 35, tackle system 36, operating system 37, its assembly relation and effect are not difficult to be found out in conjunction with its title by figure.
During use, by operating system, can control pneumatic distribution valve, make pressurized air enter plunger shaft, and then order about the piston horizontal displacement, drive parallel motion of reel, one side is rotated around ball screw, realizes the lifting action of steel wire cable.Facts have proved that the air counterbalance of present embodiment hangs compact conformation, easy to operate, dexterous safety, can make the weight that is hung in the space, be in the quick condition of agravicization, be convenient to accurate location, be widely used in various lifting occasions.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
