Background technology
Conventional double-speed winch is by a double-speed motor band movable reel running at present, high and low two kinds of rotative speeds are provided, due to double-speed motor behavior of structure, its rotating speed and the proportional relation of motor coil winding, common double-speed motor has 2:1, two kinds of 4:1, along with marine crane uses in more inflammable and explosive special operation environment, common speed ratio cannot meet user's operating needs, if adopt special motor, exist research and development difficulty very big, productive costs is high, does not possess the problems such as commonality.
Utility model content
The purpose of this utility model is to provide a kind of electronic explosion-proof hoisting winch, and the explosion-proof performance that it can solve conventional double-speed winch is low, the narrow problem of high low speed output ratio coverage.
In order to address the above problem, the technical solution adopted in the utility model is: include reel and be connected to slowspeed machine and the high-speed electric expreess locomotive of described reel two end axles, it is characterized in that: described reel one end axle is connected with described slowspeed machine by the first parallel shafts drop-gear box, the first planetary reduction box, explosion-proof clutch open in usual successively; Described reel other end axle is connected with described high-speed electric expreess locomotive by the second parallel shafts drop-gear box, the second planetary reduction box successively.
In technique scheme, technical scheme can also be more specifically: the output gear axle head of described the first parallel shafts drop-gear box and described the second parallel shafts drop-gear box is provided with explosion-proof drg.
Further, the input gear axle head of described the first parallel shafts drop-gear box and described the second parallel shafts drop-gear box is provided with explosion-proof drg.
Further, the mouth of described slowspeed machine and described high-speed electric expreess locomotive is provided with explosion-proof drg.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the part of the utility model except framing member all adopts conventional products, is convenient to design, produces and safeguards.
2, two single-speed motors drive the drop-gear box that is distributed in winch two ends to drive winch operation, by the coupling of the motor of friction speed and the drop-gear box of different speed ratios, realize the high low speed range regulation of winch broadness, break through the optional scope of conventional double-speed motor speed proportional.
3, two single-speed motors, drg and power-transfer clutchs are selected explosion proof type, can meet the applying working condition of winch in inflammable and explosive special operation environment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Embodiment 1 shown in Fig. 1, includes reel 6, and reel 6 one end axles are connected with slowspeed machine 1 by explosion-proof drg 5, the first parallel shafts drop-gear box 4, the first planetary reduction box 3, explosion-proof clutch open in usual 2 successively; Reel 6 other end axles are connected with high-speed electric expreess locomotive 7 by explosion-proof drg 10, the second parallel shafts drop-gear box 9, the second planetary reduction box 8 successively.
Slowspeed machine connects planetary reduction box by explosion-proof clutch open in usual, and while guaranteeing that high-speed electric expreess locomotive drives winch work, slowspeed machine can be because of drop-gear box speed ratio speed-raising driving; Planetary reduction box is connected with reel through one group of parallel shafts drop-gear box, the long design challenges of axial length of avoiding motor, reel coaxially to cause; Parallel shafts drop-gear box uses as wall frame, compact conformation, and it is convenient to install.
Because the high low speed of electronic explosion-proof hoisting winch operates as two motor independent inputs, so just can realize the optional speed ratio of relative broad range by adjusting drop-gear box speed ratio, the ratio coverage of planetary reduction box is greatly between 10～1000 at present, single-stage parallel shafts drop-gear box ratio coverage is greatly between 1～6, using under motor (4 utmost point motors that synchronous speed the is 1500r/min) prerequisite of identical input speed, can realize the high low speed output of 600:1; When high speed gear motor adopts 2 utmost point motors that synchronous speed is 3000r/min, when low gear motor adopts 8 utmost point motor that synchronous speed is 750r/min, the high low speed output speed ratio of electronic explosion-proof hoisting winch can reach 2400:1.
In the time that electronic explosion-proof hoisting winch is selected high-speed cruising, slowspeed machine 1 power-off, explosion-proof clutch 2 power-off open in usual are opened, and explosion-proof drg 5 energisings are opened, and start high-speed electric expreess locomotive 7; In the time that electronic explosion-proof hoisting winch is selected low cruise, high-speed electric expreess locomotive 7 power-off, explosion-proof drg 10 energisings are opened, and start slowspeed machine 1.
Except above-described embodiment 1, explosion-proof drg can also be contained in the input gear axle head of the first parallel shafts drop-gear box 4 and the second parallel shafts drop-gear box 9, or be contained on the mouth axle of slowspeed machine 1 and high-speed electric expreess locomotive 7, in the time that winch requires single brake structure, select above-mentioned wherein 1 position that explosion-proof drg is installed, in the time that winch requires two brake structure, select above-mentioned wherein 2 positions that explosion-proof drg is installed.
In the time of user's needs three, four-speed electronic explosion-proof hoisting winch, only need that single speed fire proof motor is replaced by double-speed motor and just can realize, for example third gear speed ratio 55:30:15, fourth gear speed ratio 100:36:25:18.
