Abstract
The invention relates to an integrated hydraulic segmented damping reel which belongs to the field of lifting machinery. The integrated hydraulic segmented damping reel is technically characterized in that a screw shaft and a piston which is meshed with the screw shaft are arranged in the integrated hydraulic segmented damping reel, a plurality of guide bars pass through the piston, a plurality of hydraulic medium channels which can regulate flow are arranged in the screw shaft, and the segmented damping brake of the integrated hydraulic segmented damping reel can be realized through the flow regulation of the channels. The invention directly replaces the reel in the lifting machinery, and when external brake force which controls and drives a roller disappears caused by the failure of a machine member, the integrated hydraulic segmented damping reel can limit the falling speed of lifter loads in a segmented mode, thereby realizing safety protection. The invention can also meet requirements of the work state of a fireproof curtain. The integrated hydraulic segmented damping reel can work in a power-free state, has small volume, can repeatedly operate for a long time without maintenance and overcomes the defects of the prior art.
Description
Technical field
The invention belongs to the lifting machinery field, especially reach the integrated hydraulic segmented damping reel of speed segmentation restriction in the lifting process with the hydraulic segmented damping mode.
Background technology
The existing lifting machinery that reaches the lifting weight by reel folding and unfolding steel rope, steel band or other traction things, undamped device in its reel, in the lifting process if the control of no personnel or other modes, its speed can not be adjusted, cut off the power supply, during accident such as braking, power link are malfunctioning, its descending speed is uncontrollable especially, and for example: the brake failure of jacking equipment can make weight pound earthward with the speed as the free-falling body, causes property damage and personal injury.And for example: the safety curtain that uses in the critical facilitys such as stage, market, library, museum, requirement can be under the condition of outage, segmentation is with different speed landing, so that can isolate burning things which may cause a fire disaster fast personnel are withdrawn if having time, existing safety curtain closing operator, or volume is bigger, complex structure, or can not repeated use.As utility model patent 89200327.8,00243067.3 and patent of invention 200510014819.4 etc., just there is above deficiency respectively.
Summary of the invention
The objective of the invention is to overcome the shortcoming that prior art exists, for spool type elevator and safety curtain provide integrated hydraulic segmented damping reel a kind of integrated small size, repeatedly used, segmentation adjustable speed damping brake.
Technical scheme of the present invention is summarized as follows:
Integrated hydraulic segmented damping reel, by the reel, screw shaft, the piston that is meshed with screw shaft, pilot bar of band axle drive shaft, prop up and be configured to, the axle drive shaft of this reel is driven by the rotation type of drive, screw shaft is arranged in the reel, the hydraulic medium passage is arranged in the screw shaft, the control cock of regulating rate-of flow is arranged in the passage, the piston that is meshed with screw shaft is arranged in the reel, there are several to parallel and through the pilot bar of piston, the two ends of reel are fixed at the two ends of pilot bar with screw shaft.
Hydraulic medium passage in the screw shaft is positioned at screw shaft, is one or more passages, and the opening of passage is positioned at radially screw thread place of screw shaft.
The effect of pilot bar is that piston is rotated jointly with reel, and at the effect lower edge of screw shaft axial motion.
The present invention has following advantage:
1, the jacking equipment that can be all spool types provides a kind of security protection system, can protect any mechanical hardover failure except that traction thing fractures such as steel rope.Prevent because of reel drive in the link any one malfunctioning as: axle key damages, and coupler fracture, axle drive shaft fracture, gear damage, malfunctioning or the like the load free falling phenomenon that causes of newspaper lock.
2, compact conformation, volume is little, and Installation and Debugging are simple.Can directly replace original common reel.
3, hydraulic medium passage and control cock are arranged in static screw shaft, therefore electric controlled regulating valve can be installed, and reach other built-in or external pressure, flow detection control system.
4, the operation of can cutting off the power supply. even run on the environment that does not have power supply, especially when being applied to the special fireproof curtain, can save those only install and debugging in the just driven by power and the electric control appliance of use.
5, safe and reliable, can prolonged and repeatedly move, and be easy to regulate, for ease of maintenaince.
Description of drawings
Below in conjunction with embodiment shown in the drawings the present invention further is illustrated, present embodiment only is used for the present invention is described and does not limit the present invention.
Fig. 1 is the structure cutaway view of one embodiment of the invention.
Wherein: 1 control cock, 2 axle keys, 3 bearing support, 4 oil circuit B, 5 pilot bars, 6 reels, 7 screw shafts, 8 pistons, 9 pilot bars, 10 hydraulic oil, 11 oil circuit C, 12 hydraulic oil, 13 steel ropes, 14 thrust barings, 15 bearing support, 16 axle drive shafts, 17 connect oil circuit, 18 stifled cores, 19 oil circuit A.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated:
This integrated hydraulic segmented damping reel, support by bearing support 3,15, input shaft 16 is driven by the rotation type of drive, driving reel 6 rotates, the outside face of reel 6 is wound with the band shape traction thing of traction weight, is steel rope 13 in the present embodiment, and reel 6 rotates and drives steel rope 13 retractables, the other end of steel rope 13 hangs weight or safety curtain (omitting among the figure), the ascending, descending with the retractable of 6 pairs of steel ropes 13 of reel.During rising: reel 6 rotations are also collected steel rope 13, piston 8 in the reel 6 is because the drive of pilot bar 9, rotate synchronously with reel 6, screw shaft 7 is made it to maintain static by axle key 2, piston 8 is screw-threaded engagement with screw shaft 7, under the effect of thread engagement, the piston 8 of rotation moves to the right, and the hydraulic oil 10 on extruding right side arrives the left side of pistons 8 by oil circuit C 11, perforation oil circuit 17 and oil circuit B 4, oil circuit A 19.During decline, above-mentioned motion process is then opposite.In the normal lifting process, owing to do not reach limited speed, the flow of hydraulic oil is very little, and each asphalt channel is very little to the resistance of hydraulic oil, does not influence rising or falling speed.Part fails such as newspaper lock when weight-lifting equipment, or safety curtain is in the fire starting state, this moment, reel 6 lost braking and the power from axle drive shaft 16, under the effect of gravity, hang steel rope 13 hitch wheels, 6 fast rotational of weight or safety curtain and discharge steel rope 13, piston 8 is moved to the left, because flow strengthens, asphalt channel and control cock 1 convection current quantitative limitation, the left side of piston 8 is subjected to the thrust of hydraulic oil 10, hinder piston 8 moving velocity left, made the rotative speed of reel 6 be restricted, controlled the descending speed of weight or safety curtain.When piston 8 continues to be moved to the left and to hide the oilhole of oil circuit A 19, this oil circuit is blocked, the speed that moves to left of piston 8 further slows down, reel 6 discharges steel rope 13 and slows down, and the descending speed of weight or safety curtain also further slows down thereupon, with continuing to move to left with after oil circuit B 4 blocking-up by piston, hydraulic oil only can be by the engaged gap infiltrate between piston 8 and the screw shaft 7, with making that the descending speed of weight or safety curtain is slower, so just reached segmented damping, the effect of control rate.Regulate three control cocks 1 respectively, can regulate each section speed respectively, make it to reach requirement.
In addition, if extract the spool of three control cocks 1 out, external oil pressure detects and flow control element, can start damping control as required at any time.
