Description
Technical field
The utility model relates to the hydraulic engineering field, particularly relates to a kind of arrangements for speed regulation of fast opening and closing.
Background technology
QPK series gate hoist is widely used the keying of hydraulic engineering stop gate as a kind of fast opening and closing of JB3094-82 regulation.Regulation according to standard, closing velocity is all at 4M/min～5M/min, working method opens and closes by the motor drives works gate that rises and falls for conventional, when the needs quick closedown, open the brake band-type brake, gate freely falling body fast-descending, when excessive velocities, the action of the mechanical adjustable speed drive of high speed shaft coaxial linkage reduces the rotating speed of axle by the continuous clutch of taper brake disc on conical friction sheet and the fixed bearing, thus with velocity-stabilization in control range.
But in normal use procedure, find following problem:
1. be subjected to processing technology and horizontal constraints is installed, conical surface decentraction or the cone angle of taper sheath and taper brake disc do not wait, and the conical friction sheet partly contacts with brake disc in braking procedure, and the friction plate concentrated wear is serious, and the governor heating is uneven.
2. if selected friction plate poor quality sends huge ear-piercing sound during use, some also can give out a large amount of flue dust.
3. friction plate uses an end just wearing and tearing or aging after the time, must change, and affect the normal use of headstock gear, and the friction plate of replacing and the concentricity of brake disc can't be well controlled.
4. if lift is excessive, friction plate can be in running order for a long time, causes the brake disc temperature rise too high, and reliability greatly reduces, and can have influence on application life.
5. not too high in order to guarantee brake disc work temperature rise, needs increase weight, the area of dissipation of brake disc,, so the centrifugal speed governor profile in the large-scale keying is all very large.

The technical problem that the utility model mainly solves provides a kind of arrangements for speed regulation of fast opening and closing, can realize infinitely variable speeds, and speed is regulated smooth-going and reliable, use not limit by lift, and long service life, cost is low, and is simple in structure, and it is little to generate heat, noiselessness.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the arrangements for speed regulation that a kind of fast opening and closing is provided, comprise: housing, be provided with oil pump, pipeline and adjusting device in the described housing, be connected by pipeline between described adjusting device and the oil pump, be provided with vane group in the described oil pump, described adjusting device comprises control valve, spool and elastic component, one end of described spool is connected with control valve, the other end of spool is connected with elastic component, and described spool and control valve are connected to form damping hole.
In preferred embodiment of the utility model, described pipeline comprises the first pipeline and the second pipeline, and described the first pipeline is connected with the left end of adjusting device, and described the second pipeline is connected with the right-hand member of adjusting device.
In preferred embodiment of the utility model, described elastic component is spring.
In preferred embodiment of the utility model, described vane group comprises 3 blades.
In preferred embodiment of the utility model, be connected with headstock gear on the described vane group.
The beneficial effects of the utility model are: the arrangements for speed regulation of the utility model fast opening and closing can be realized infinitely variable speeds, and speed is regulated smooth-going and reliable, use not limit by lift, and long service life, cost is low, and is simple in structure, and it is little to generate heat, noiselessness.
Description of drawings
Fig. 1 is the structural representation of arrangements for speed regulation one preferred embodiment of the utility model fast opening and closing;
The mark of each parts is as follows in the accompanying drawing: 1, housing, and 2, oil pump, 3, pipeline, 4, adjusting device, 21, vane group, 22, blade, the 31, first pipeline, the 32, second pipeline, 41, control valve, 42, spool, 43, elastic component.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of arrangements for speed regulation of fast opening and closing, comprise: housing 1, be provided with oil pump 2, pipeline 3 and adjusting device 4 in the described housing 1, be connected by pipeline 3 between described adjusting device 4 and the oil pump 2, be provided with vane group 21 in the described oil pump 2, described adjusting device 4 comprises control valve 41, spool 42 and elastic component 43, one end of described spool 42 is connected with control valve 41, and the other end of spool 42 is connected with elastic component 43, and described spool 42 and control valve 41 are connected to form damping hole.
In addition, described pipeline 3 comprises the first pipeline 31 and the second pipeline 32, and described the first pipeline 31 is connected with the left end of adjusting device 4, and described the second pipeline 32 is connected with the right-hand member of adjusting device 4.
In addition, described elastic component 43 is spring, thereby spool 42 is because the pressure of hydraulic oil moves, and spring can make the spool 43 after moving automatically reset.
In addition, described vane group 21 comprises 3 blades 22.
In addition, be connected with headstock gear on the described vane group 21, vane group 21 is connected with the headstock gear of external gate, by adjusting the rotary speed of vane group 21, the falling speed of regulating gate.
The arrangements for speed regulation specific works principle of the utility model fast opening and closing is as follows: when vane group 21 turns clockwise, hydraulic oil enters into adjusting device 4 inside through the first pipeline 31, then because pressure, spool 42 is promoted to the right, and then hydraulic oil flows out adjusting device 4 and again refluxes in the oil pump 1 through the second pipeline 32; When vane group 21 is rotated counterclockwise, spool 42 is got back to initial position under the thrust of spring, oil flow in the adjusting device 4 by the second pipeline 32, thereby flow into the inside of spool 42, then flow out damping hole, get back to oil pump 2 inside by the first pipeline 31, the 21 one-tenth undamped states of vane group in the oil pump 2; When needs are adjusted the rotary speed of vane group 21, control valve 41 to be regulated, the size that changes damping hole is controlled the speed of hydraulic oil, the rotary speed of the vane group 21 in the final control oil pump 2; The axis of rotation of vane group 21 is connected to the high-speed rotating shaft of headstock gear, thereby when realizing that headstock gear is opened, be the undamped state, when the needs Rapid door closer, vane group 21 is driven and is rotated counterclockwise, control the rotary speed of vane group 41 by the speed of control valve 41 regulator solution force feeds, thus the falling speed of regulating gate.
Be different from prior art, the arrangements for speed regulation of the utility model fast opening and closing can be realized infinitely variable speeds, and speed is regulated smooth-going and reliable, use not limit by lift, and long service life, cost is low, and is simple in structure, and it is little to generate heat, noiselessness.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
