Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
As shown in Figure 1, medical hoist tower brake system of the present invention, comprises air compressor 1, gas holder 2, final controlling element 3 and the first Qi Sha mechanism 4 and the second Qi Sha mechanism 5.
Be connected tracheae 13 by first between air compressor 1 with gas holder 2 to be connected.Air compressor 1 can produce pressurized air, provides compressed gas source for giving medical hoist tower brake system.The air compressor 1 of medical hoist tower brake system of the present invention is independently equipment, only for providing compressed gas source to the brake system of a medical hoist tower.In other words, every exactly platform medical hoist tower is equipped with an independently air compressor 1, and this air compressor 1 volume is relatively little, is easy to carry and installs.This provide the mode of source of the gas be different from existing hospital set up, the air compression system of source of the gas is provided to the brake system of a large amount of medical hoist towers.
The pressurized air that air compressor 1 produces connects tracheae 13 by first and is input in gas holder 2, and gas holder 2 just can save a certain amount of pressurized air, as bailout gas, thus reduces the frequent starting of air compressor.
Sense cell 12 is also connected with, for responding to the compressed-air actuated pressure in gas holder 2 between air compressor 1 and gas holder 2.When the pressurized air in gas holder 2 is lower than setting value, air compressor 1 is energized and produces pressurized air, connects tracheae 13 input in gas holder 2 by first; When the compressed-air actuated pressure in gas holder 2 reaches setting value, air compressor 1 power-off quits work.Preferably, sense cell 2 is sensor.
The outlet side of gas holder 2 connects tracheae 14 by second and is connected with final controlling element 3.Preferably, final controlling element 3 is solenoid valve.Preferably, final controlling element 3 is connected with AC220V or DC24V power supply.The outlet side of final controlling element 3 connects tracheae the 15, four connection tracheae 16 by the 3rd and is connected with the second Qi Sha mechanism 5 with the first Qi Sha mechanism 4 respectively.By power-off and the energising of final controlling element 3, control the current of the compressed gas source of supply first Qi Sha mechanism 4 and the second Qi Sha mechanism 5 or release.Due to the set-up mode of final controlling element 3 power-off conducting, make compressed gas source be in current state always, even if the unexpected power-off of power supply system, also can not affect the braking locking function of the first Qi Sha mechanism 4 and the second Qi Sha mechanism 5, for user provides safe guarantee.
Preferably, first connects tracheae 13, second connection tracheae the 14, three connection tracheae the 15, three connection tracheae 16 is flexible pipe, such as polyurethane flexible pipe.
Shown in Fig. 2, it be the cross section of the first air-bag base 41, first air-bag base 41 of arc is spill that the first Qi Sha mechanism 4 comprises length direction, and the first air bag 42 is housed in the first air-bag base 41.It is that the cross section of the second air-bag base 51, second air-bag base 51 of arc is similarly spill that second Qi Sha mechanism 5 comprises length direction, and the second air bag 52 is housed in the second air-bag base 51.First air bag 42 and the second air bag 52 are made up of elastic material, and preferably, this elastic material is silica gel.
Medical hoist tower brake system of the present invention also comprises the rotating machinery coordinated with the first Qi Sha mechanism 4 and the second Qi Sha mechanism 5.
As shown in Figure 2, rotating machinery comprises chassis 6, is fixedly mounted on the axle core 7 on chassis 6, and is rotatably installed in the wheel hub 8 on axle core 7 by the first tapered bearing 10 and the second tapered bearing 11.
First tapered bearing 10 and the second tapered bearing 11 are fixedly mounted on the outer circumferential face of axle core 7, the inner peripheral surface of wheel hub 8 are formed with protruding 81.During assembling, protruding 81 are arranged between the first tapered bearing 10 and the second tapered bearing 11, and connect with it respectively, and wheel hub 8 just can rotate by axle core 7 relatively.
Wheel hub 8 has lower end surface 82, and chassis 6 has upper-end surface 61, is formed with annular groove between lower end surface 82 and upper-end surface 61, and the first Qi Sha mechanism 4 and the second Qi Sha mechanism 5 are just housed in this annular groove respectively.First air-bag base 41 and the second air-bag base 51, by screw or other fixed elements, are separately fixed on the upper-end surface 61 on chassis 6.Certain gap is provided with between the upper-end surface of the first air-bag base 41 and the second air-bag base 51 and the lower end surface 82 of wheel hub 8.
The working principle of medical hoist tower brake system of the present invention is: when sense cell 12 senses that compressed-air actuated pressure in gas holder 2 is lower than predetermined value, air compressor 1 is energized work, produce pressurized air, pressurized air connects tracheae 13 by first and is input in gas holder 2.Enough pressurized air is had in gas holder 2, and during final controlling element 3 power-off conducting, pressurized air just can connect tracheae 14, final controlling element 3 and the 3rd connection tracheae 15, the 4th by second and connect tracheae 16, be input in the first air bag 42 of the first Qi Sha mechanism 4 and the second air bag 52 of the second Qi Sha mechanism 5 respectively, air bag 42,52 are just in inflated condition separately, make the first air bag 42 and the second air bag 52 cokled surface like this, and contact with the lower end surface 82 of the wheel hub 8 of rotating machinery respectively, produce frictional force locking wheel hub 8, thus reach braking function.
When the wheel hub 8 of rotating machinery will be made to rotate, by user operation, final controlling element 3 is energized, thus the gas in the first air bag 42 and the second air bag 52 is released, the then surface retraction of the first air bag 42 and the second air bag 52, restPose, disengage with the lower end surface 82 of the wheel hub 8 of rotating machinery respectively, then frictional force disappears thereupon, wheel hub 8 just can rotate relative to axle core 7, thus reaches spinfunction.
Again make final controlling element 3 power-off by user operation, then the first air bag 42 and the second air bag 52 are inflated again, and frictional force produces again, and the wheel hub 8 of rotating machinery is locked again.Control final controlling element 3 power-off, energising by user operation, control the inflation of the first air bag 42 and the second air bag 52, venting, thus lock and unclamp the wheel hub 8 of rotating machinery, realize braking and spinfunction.
Air compressor 1 due to medical hoist tower brake system of the present invention is independently equipment, independently compressed gas source can be provided for the first Qi Sha mechanism 5 of Qi Sha mechanism 4, second, so user does not need to drop into a large amount of expenses set up air compression system, do not need to be installed to gas pipeline when capital construction to use scene, reduce input cost yet.
The brake system of every platform tower crane is all equipped with the air compressor 1 independently providing compressed gas source, and thus every platform tower crane all can control locking and the releasing orientation of rotating machinery independently, can not cause the inefficacy of all tower crane brake system because of a set of air compression system fault.
