Abstract
The invention discloses a small lifter which comprises a hydraulic motor, a lifting device and a constant moment gear device, wherein the hydraulic motor comprises a gear roller, the lifting device comprises a coiling roller, a steel rope and an objective table, and the constant moment gear device comprises a gear chuck, an elastic element and a cylindrical pin; the gear roller is connected with the coiling roller, and the steel rope connects the coiling roller with the objective table; the gear chuck is mounted on the gear roller, the elastic element is mounted on the inner wall of the coiling roller, and the cylindrical pin is mounted on the elastic element and connected with the gear chuck. According to the small lifter, when the weight of objects on the objective table is larger than elastic force, the cylindrical pin on the gear chuck can compress the elastic element, so that the gear chuck idles, the coiling roller does not rotate, the too large pre-tightening force is prevented, the hydraulic motor is prevented from being overloaded, and therefore the lifter is protected.
Description
Technical field
The present invention relates to vehicle for construction applied technical field, be specially a kind of dumbwaiter.
Background technology
The small-sized lifting type of prior art gets more and more, instead of manpower transport's building materials gradually, achieves mechanization production gradually, greatly reduces the input of manpower, further increase work efficiency.But in the process of regular job, the situation that HM Hydraulic Motor burns out because of overload can be run into, so we design the excessive elevator of a kind of small-sized prevention predetermincd tension, greatly can carry and do economic benefit.
Summary of the invention
The object of the present invention is to provide a kind of dumbwaiter, it can solve Problems existing in background technology by actv..
For achieving the above object, the invention provides following technical scheme: a kind of dumbwaiter, comprise HM Hydraulic Motor, jacking system and determine torque gear device, described HM Hydraulic Motor comprises gear roller bearing, described jacking system comprises serving roller bearing, steel cable and objective table, describedly determine torque gear device and comprise wheel chuck, elastic element and straight pin, described gear roller bearing is connected with serving roller bearing, described steel cable connects serving roller bearing and objective table, described wheel chuck is arranged on gear roller bearing, described elastic element is arranged on serving roller bearing inwall, described straight pin is arranged on elastic element, and be connected with wheel chuck.
Preferably, described HM Hydraulic Motor also comprises oil inlet and oil outlet, its middle gear roller bearing comprises gear, oil outlet and oil inlet are arranged on HM Hydraulic Motor top, oil inlet is communicated with oil outlet, and gear is arranged on gear wheel shaft, by controlling oil inlet input hydraulic pressure oil, fluid Sports band moving gear rotates, and gear roller bearing rotates thereupon.
Preferably, described jacking system also comprises fixed pulley, and fixed pulley connects steel cable, reduces steel cable friction force by fixed pulley.
Compared with prior art; the invention has the beneficial effects as follows: this dumbwaiter can change the moment of elasticity size of determining elastic element in torque gear device; protection HM Hydraulic Motor is not damaged because of overload; if objective table weight of object exceedes the elastic force size pre-set; straight pin meeting compression elastic element on wheel chuck; wheel chuck is dallied; serving roller bearing does not rotate; prevention predetermincd tension is reached excessive with this; prevent HM Hydraulic Motor overload, thus protection elevator is not impaired, simple and practical; easy to use, be easy to promote.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present invention;
Fig. 2 of the present inventionly determines torque gear setting plane.
In Reference numeral: 1, HM Hydraulic Motor, 11, oil inlet, 12, oil outlet, 13 gear roller bearings, 131, gear, 2, jacking system, 21, serving roller bearing, 22, steel cable, 23, fixed pulley, 24, objective table, 3, torque gear device is determined, 31, wheel chuck, 32, straight pin, 33, elastic element.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, the invention provides a kind of technical scheme: a kind of dumbwaiter, comprise HM Hydraulic Motor 1, jacking system 2 and determine torque gear device 3, HM Hydraulic Motor 1 comprises oil inlet 11, oil outlet 12 and gear roller bearing 13, gear roller bearing 13 comprises gear 131, jacking system 2 comprises serving roller bearing 21, steel cable 22, fixed pulley 23 and objective table 24, determine torque gear device 3 and comprise wheel chuck 31, straight pin 32 and elastic element 33, oil outlet 11 and oil inlet 12 are arranged on HM Hydraulic Motor 1 top, gear 131 is arranged on gear roller bearing 13, oil inlet 11 is communicated with oil outlet 12, high-pressure and hydraulic fluid is inputted by controlling oil inlet 11, hydraulic oil liquid fluxion strap moving gear 131 rotates, gear roller bearing 13 rotates thereupon, hydraulic oil liquid exports by oil outlet 12, again be input to oil inlet 11 li, realize hydraulic oil liquid to circulate, ensure that gear continues to rotate, propulsion source is provided, gear roller bearing 13 is connected with serving roller bearing 21, fixed pulley 23 connects steel cable 22, reduce friction, steel cable 22 connects serving roller bearing 21 and objective table 24, wheel chuck 31 is arranged on gear roller bearing 13, elastic element 33 is arranged on inside serving roller bearing 21, straight pin 32 is arranged on elastic element 33, and be connected with wheel chuck 31, pre-set the elastic force that elastic element 32 carries, elastic force is less than the twisting resistance of HM Hydraulic Motor 1 gear roller bearing 13 in theoretical value, when the quality of the building materials of objective table 24 is greater than elastic force time, straight pin 32 meeting compression elastic element 33 on wheel chuck 31, wheel chuck 31 is dallied, serving roller bearing 21 does not rotate, prevention predetermincd tension is reached excessive with this, prevent HM Hydraulic Motor 1 overload, thus protection elevator is not impaired.
Principle of design of the present invention is: the elastic force size of torque gear device 3 li of elastic elements 33 determined by this dumbwaiter by changing; protection HM Hydraulic Motor 1 is not damaged because of overload; if objective table 24 weight of object exceedes the elastic force size pre-set; straight pin 32 meeting compression elastic element 33 on wheel chuck 31; wheel chuck 31 is dallied, and serving roller bearing 21 does not rotate, and reaches prevention predetermincd tension excessive with this; prevent HM Hydraulic Motor 1 overload, thus protection elevator is not impaired.
