Distribution valve body top one side of described distribution assembly is provided with gas source air inlet, valve is positioned at the inboard neck location of distribution valve body, the housing of distribution valve body neck is provided with air extractor duct, this air extractor duct is connected with infrastigmatal air flue, the distribution assembly is connected with brake assembly by bonded assembly tracheae line on this air extractor duct, on the housing of distribution valve body, lead to and distribute the position of valve pocket to be provided with leakage port, this leakage port is communicated with bonded assembly tracheae line on the air extractor duct by the tracheae line, the inboard of leakage port all is communicated with distributing valve pocket and distribution spool, distributes the disappointing road on the spool to communicate with leakage port when the position that the air winch meta stops.
The utility model is provided with torque limiter between speed reduction gearing and motor assembly output shaft, to realize overload protection, improve the device security performance, the protection lifting means, thus improved safety; The utility model has adopted disk type brake mechanism and hand-operated brake mechanism simultaneously, has improved safety and reliability more; The utility model has on the distribution valve body and increases that to be provided with two gas ports be air extractor duct and leakage port, one at distribution valve body neck, side at the distributing valve of distribution valve body, the tracheae line that leads to brake assembly is simultaneously together with these two gas ports, valve is opened compressed gas source and is ventilated to brake assembly by the air extractor duct of distribution valve body neck, remove brake, another leakage port is in closed condition; Valve closure, the air extractor duct of distribution valve body neck is not just to the logical compressed gas source of brake assembly, the leakage port that this moment, the distribution valve body led to distributing valve is just in time opened, pressurized air in the brake assembly cylinder is discharged, and the brake assembly braking under action of the spring improves the reliability of braking.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the R portion enlarged drawing of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise distribution assembly 1, housing piston assembly, speed reduction gearing 4, reel 5, brake assembly 7 and left and right support, described reel 5 is arranged between the two stands, brake assembly 7 is arranged on the outside of left socle, distribution assembly 1 is arranged on the housing piston assembly and forms motor assembly, motor assembly is installed in the outside of right support, is provided with hand-operated brake assembly 3 between the reel 5 wheel rims outside and right support.Described brake assembly 7 is the disk type brake structure, and distribution assembly 1 is connected with brake assembly 7 by the tracheae line, and described speed reduction gearing 4 is arranged on reel 5 inside, and speed reduction gearing 4 is connected with the motor assembly output shaft by torque limiter 2.
Distribution valve body top one side of described distribution assembly 1 is provided with gas source air inlet 10, source of the gas leads to distributing valve by valve 9, valve 9 is positioned at the inboard neck location of distribution valve body, the housing of distribution valve body neck is provided with air extractor duct 8, this air extractor duct 8 is connected with air flue under the valve 9, giving vent to anger of valve 9 control air extractor ducts 8, distribution assembly 1 is connected with brake assembly 7 by bonded assembly tracheae line on this air extractor duct 8, on the housing of distribution valve body, lead to the position of distributing valve pocket and be provided with leakage port 11, these leakage port 11 outsides are communicated with bonded assembly tracheae line on the air extractor duct 8 by pipeline, air extractor duct 8 and leakage port 11 are communicated with brake assembly 7 by the tracheae line simultaneously, two gas ports do not open or close simultaneously, as long as a gas port is opened, other closes by a gas port.The inboard of leakage port 11 all is communicated with distributing valve pocket and distribution spool, distributes the disappointing road on the spool to communicate with leakage port 11 when the position that the air winch meta stops.
Disk type brake brake assembly 7 of the present utility model is the normally closed structure, and promptly air winch stops or blocks the pressurized air that certain pressure is not arranged to brake assembly 7 passbands under the source of the gas state, and brake assembly 7 is in braking state, and reel 5 can not rotate.Disk type brake mechanism in the present embodiment is in the form of piston, can also be air sac.When winch needs work, by handle 6 Control Allocation valves valve 9 is opened, gas is entered through valve 9 by gas source air inlet 10 and is redistributed in the distributing valve in the distributing valve, and a gas part that enters in the valve 9 enters brake assembly 7 through air extractor duct 8, so just remove brake, reel 5 can be worked; Simultaneously, another part enters the interior gas of distributing valve through distributing valve and leads to cylinder liner, promotes piston and back and forth does manual work, and the gas motor assembly is started working, and motor assembly output is rotated drive reel 5 work of doing manual work and realized dipping and heaving.When needs reel 5 quit work, handle 6 Control Allocation valves cut out valve 9, and reel 5 sides quit work, and at this moment discharge in the disappointing road got back on the distributing valve by the tracheae line of the indoor gas of the brake air of brake assembly 7.
