Abstract
The utility model discloses a rotary driving system of a tower crane for a crane, which comprises two hydraulic motors. Transmission gears are fixed on output shafts of the two hydraulic motors. A gear ring is fixed on a tower body of the tower crane. The transmission gears are in meshed transmission with the gear ring to drive the tower body to rotate. In the rotary driving system of the tower crane for the crane, one motor controls two hydraulic motors to work and hydraulic motors control the tower body and a large arm to rotate, so that the rotary driving system of the tower crane for the crane has a simple structure and is convenient to control, has low noise and good reliability, rotates stably, and can be conveniently used for the processing and installation of the rotary table.
Description
Technical field
The utility model relates to hoisting crane.
Background technology
Tower crane is the rotary crane that swing arm is contained in towering body of the tower top.Working space is big, is mainly used in the installation of vertical and the horizontal feed and the building element of material in the housing construction.Form by metal construction, operating mechanism and electric system three parts.Metal construction comprises body of the tower, swing arm and base etc.Operating mechanism hoists, luffing, revolution and walking four parts.The revolution of body of the tower causes turntable processing technology complicacy on the tower machine, difficult installation like this with two fluid couplings in the prior art.
The utility model content
The utility model technical matters to be solved just provides a kind of tower machine gyroscopic drive system of hoisting crane, and is simple in structure, and control is convenient, also is convenient to the processing and the installation of body of the tower turntable.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the tower machine gyroscopic drive system of hoisting crane; It is characterized in that: comprise two HM Hydraulic Motors; Be fixed with transmission gear on said two hydraulic motor output shaft, a fixing gear ring on the tower machine body of the tower, said transmission gear and gear ring engaged transmission drive the body of the tower rotation.
The utility model is with two HM Hydraulic Motor work of an electric machine control, and is simple in structure with the revolution of hydraulic motor controlled body of the tower and big arm, and control is convenient, also is convenient to the processing and the installation of turntable, and revolution steadily, and noise is little, good reliability.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the utility model hydraulic system structure schematic diagram.
The specific embodiment
As shown in Figure 1; Tower machine gyroscopic drive system for the utility model hoisting crane comprises two HM Hydraulic Motors 1, is fixed with transmission gear on said two hydraulic motor output shaft; A fixing gear ring on the tower machine body of the tower, said transmission gear and gear ring engaged transmission drive the body of the tower rotation.
Because the rotation of slewing tower is the large gear ring and the engagement of the small transmission gear on the hydraulic motor output shaft of leaning on the slewing tower; Drive the rotation of slewing tower through the rotation of miniature gears; So revolving table left-hand revolution during the HM Hydraulic Motor clickwise, slewing tower clickwise during the HM Hydraulic Motor left-hand revolution.
P oil inlet, T return opening among the figure.Open electrical motor 8, make oil pump 7 work.
(1) HM Hydraulic Motor clickwise.
1, shifts the handle of two two position and four-way reversing valves 2 onto B mouth position, make two position and four-way reversing valves be in off condition;
2, shift the handle of three position four-way directional control valve 3 onto the A mouth, hand can not be decontroled, and HM Hydraulic Motor 1 beginning clickwise after slewing tower left-hand revolution, slewing tower rotate to and specify external position, is decontroled the hand of control three position four-way directional control valve 3, and the handle braking recovers.
(2) HM Hydraulic Motor left-hand revolution:
1, shifts the handle of two two position and four-way reversing valves 2 onto B mouth position, make two position and four-way reversing valves be in off condition;
2, move the handle of three position four-way directional control valve 3 to the B mouth, hand can not be decontroled, and HM Hydraulic Motor 1 beginning left-hand revolution after slewing tower clickwise, slewing tower rotate to and specify external position, is decontroled the hand of control three position four-way directional control valve 3, and the handle braking recovers.
For guaranteeing normal operation, also be provided with other annex flow regulating valve 6, by pass valve 5, compression indicator 4, filter screen 9.
Off working state:
1, closes electrical motor;
2, shift the handle of two two position and four-way reversing valves onto A mouth position, make two position and four-way reversing valves and fuel tank connected state, slewing tower can be rotated with the wind.
Claims (1)
1. the tower machine gyroscopic drive system of hoisting crane; It is characterized in that: comprise two HM Hydraulic Motors (1); Be fixed with transmission gear on said two hydraulic motor output shaft, a fixing gear ring on the tower machine body of the tower, said transmission gear and gear ring engaged transmission drive the body of the tower rotation.
