Abstract

The utility model relates to a hoister, particularly a double drum hoister which is suitable for the foundation construction of the vibration, the beating and the extracting of piles and hammers. The utility model is characterized in that interlocking one-way clutches (7), (17) which are composed of ratchet wheels (10), (13) and ratchet wheels (11), (12) are respectively arranged between rollers (6), (9) so as to cause a control mechanism to be simplified, and workers can conveniently carry out pressurization and pile extracting so long as workers press buttons to operate a control system in a cab.

Description

Double drum winding machine

The utility model relates to winch, and particularly twin drum winch is applicable to the foundation construction of pile driving by vibration pile pulling hammer.

Existing vibration is played the pile pulling hammer and is gone up the twin drum winch that adopts, owing to adopt two power-transfer clutchs, (friction-type or castellated) is equipped with corresponding brake, with the manual mode of operation vibro-driver extractor is pressurizeed and pile pulling, adopt four lever operated pretty troublesome, and be unfavorable for driving in-house operation.

The purpose of this utility model is to provide the twin drum winch of a kind of transmission device with the free-wheel clutch of a pair of interlocking, and control mechanism is simplified, and staff's operation control system of pressing a button in operator's compartment is easily pressurizeed and pile pulling.

Of the present utility model being characterised in that respectively has the free-wheel clutch of an interlocking (7), (17) between reel (6), (9), free-wheel clutch (7), (17) are made up of ratchet (10), (13) and ratchet (11), (12), ratchet (10), (13) are fixed with reel (6), (9) respectively with bolt, pack in the groove of pawl base (14) opposite to each other in ratchet (11), (12), a fan-shaped boss (16) is respectively arranged on ratchet (11), (12).

Existing accompanying drawings is as follows:

Fig. 1 is a constructional drawing of the present utility model.

Electrical motor (1) is used key connecting with retarder (2), retarder (2) is directly used key connecting with center shaft (4), reel (6), (9) are placed on the center shaft (4) by bearing, free-wheel clutch (7), (17) of an interlocking respectively are housed between reel (6), (9), center shaft (4) is bearing on the bearing seat (5), rope processing device (8) compresses steel rope, makes reel (6), (9) produce damping.

Fig. 2 is the constructional drawing of free-wheel clutch (7), (17).

Pawl base (14) connects with center shaft (4) with key, ratchet (10), (13) are fixed with reel (6), (9) respectively with bolt, ratchet (11), (12) are loaded in the groove of pawl base (14) opposite to each other, make ratchet (11), (12) projection with spring (15), a fan-shaped boss (16) is respectively arranged on ratchet (11), (12), on ratchet (11) or (12), lift, when entering mode of operation, the fan-shaped boss (16) of ratchet (11) or (12) is just retraining ratchet (11) or (12), make its can not on lift.

Now the transmission process with free-wheel clutch (7), (17) is described as follows:

Fig. 3 is the working condition figure of free-wheel clutch (7).

Fig. 4 is the working condition figure of free-wheel clutch (17).

Fig. 5 is the working diagram of fan-shaped boss (16).

When center shaft (4) when the ω direction is rotated, reel (9) does not rotate under the pressure effect of rope processing device (8), that is ratchet (13) does not rotate, and ratchet (12) is pressed in pawl base (14) groove, under the effect of spring (15), ratchet (11) is lifted on then, enter mode of operation, thereby drive ratchet (10), make reel (6) overcome damping and rotate, when ratchet (11) when entering mode of operation, the fan-shaped boss (16) that plays effect of contraction retraining ratchet (12) can not on lift, thereby realize making reel (9) be in free state, when electrical motor (1) counter-rotating drives center shaft (4) contrarotation, then reel (9) rotates, and reel (6) is in free state.

Below the utility model being used to vibrate the working process of playing the pile pulling hammer is described below:

Beat pile pulling when hammer when the utility model is used for vibration, pressurize as reel (6) is used for, reel (9) is used for the sash weight pile pulling.Press a button, make electrical motor (1) when just changeing, reel (6) pressurization, reel (9) is in free state, puts steel rope automatically; When making electrical motor (1) counter-rotating when pressing a button, reel (9) sash weight, group stake, reel (6) is in free state, puts steel rope automatically, so just can satisfy the action need of vibrating pile driver with two buttons.

Compared with the prior art, control of the present utility model can be carried out at the indoor push-botton operation of driving easily, has reduced labor intensity of operating personnel widely, and has manufacturing simply, and is in light weight, low cost and other advantages.
