Abstract
The invention discloses an integral spring damping barrel, which belongs to the field of elevating machines. The integral spring damping barrel is mainly characterized in that: the inside of the barrel is provided with a screw shaft and a piston engaged with the screw shaft; a plurality of guide rods pass through the piston; a spring is arranged in the barrel; and when the rotating barrel drives the piston rotating, the piston extrudes the spring by moving away from the screw rod in an engaged way so as to produce resistance force and realize damping brake on the barrel. The invention directlyreplaces the barrel in an elevating machine. When the external braking force for controlling and driving the barrel disappears caused by the failure of a component, an ordinary barrel causes an elevated load to be lowered because of lacking braking force. The integral spring damping barrel can limit the load falling speed of an elevator so as to realize safety protection, and can also meet the requirement on the working state of a fire-proof curtain. The integral spring damping barrel runs in power-supply-free state, has compact size, can run repeatedly for a long time almost without maintenance, and avoids the defects in the prior art.
Description
Technical field
The invention belongs to the lifting machinery field, especially reach the integral spring damping barrel of speed control in the lifting process with the spring damping mode.
Background technology
Existingly reach the lifting machinery of lifting weight by reel folding and unfolding steel rope, steel band or other traction things, general undamped device in its reel, the rising or falling speed undamped power of reel is adjusted.Other then adopts hydraulic damping or hydraulic segmented damping mode, as utility model patent 89200327.8,00243067.3 and patent of invention 200510014819.4,200810053525.6 etc.The present invention realizes the control of spool velocity can being used for jacking equipment and safety curtain in the spring damping mode, especially has the fixedly jacking equipment of lifting travel.Realize comparing with the hydraulic damping mode, have simpler, maintenance free, the longer characteristics of work life almost of processing.
Summary of the invention
The objective of the invention is to overcome the shortcoming that prior art exists, the integral spring damping barrel that provides a kind of integrated small size, repeatedly used, reaches speed control in the spring damping mode for spool type elevator and safety curtain.
Technical scheme of the present invention is summarized as follows:
Integral spring damping barrel, 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 can be driven by any known rotation type of drive, screw shaft is arranged in the reel, and the piston that is meshed with screw shaft arranged, there are several to parallel and through the piston guide bar of piston, the two ends of reel are fixed at the two ends of pilot bar with screw shaft.Spring is arranged in the reel, and described spring is more than one or one.
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, can be the jacking equipment of spool type, especially have the jacking equipment of fixed journey system, a kind of security protection system is provided, 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, safe and reliable, can prolonged and repeatedly move, and be easy to regulate, almost maintenance free maintenance.
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 axle key, 2 bearing support, 3 pilot bars, 4 reels, 5 screw shafts, 6 pistons, 7 pilot bars, 8 steel ropes, 9 thrust barings, 10 bearing support, 11 axle drive shafts, 12 spring A, 13 spring B.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated:
This integral spring damping barrel, support by bearing support 2,10, axle drive shaft 11 can be driven by any known rotation type of drive, driving reel 4 rotates, the outside face of reel 4 is wound with the rope or belt shape traction thing of traction weight, be steel rope 8 in the present embodiment, reel 4 rotates and drives steel rope 8 retractables, and the other end of steel rope 8 hangs weight or safety curtain (omitting among the figure) ascending, descending with the retractable of 4 pairs of steel ropes 8 of reel.During rising, steel rope 8 is also collected in reel 4 rotations, and the piston 6 in the reel 4 rotates with reel 4 synchronously owing to the drive of pilot bar 3,7, screw shaft 5 is made it to maintain static by axle key 1, piston 6 is screw-threaded engagement with screw shaft 5, and under the effect of thread engagement, the piston 6 of rotation moves to the right, in this example, spring is not laid on the right side of piston 6, and piston 6 moves to the right and do not stress, so undamped when rising.During decline, reel 4 contrarotations discharge steel rope 8, piston 6 moves to the left, when running to extrusion spring A12, spring B 13, spring produces piston 6 and stops its resistances that move and moving to left and increase with piston 6, this resistance has reduced the rotative speed of piston 6 and reel 4, has played the effect of damping.
When this reel is used for lifting and safety curtain system, if the part fails such as newspaper lock in the system, or safety curtain is in the fire starting state, this moment, reel 4 lost power and the braking from axle drive shaft 11, under the effect of natural gravity, hang steel rope 8 hitch wheels, 4 fast rotational of weight or safety curtain and discharge steel rope 8, piston 6 is moved to the left, when dropping to certain altitude, the left side of piston 6 at first is subjected to the thrust of spring B 13, hinder piston 6 moving velocity left, made that the rotative speed of reel 4 is slowed down, controlled the descending speed of weight or safety curtain.When piston 6 continues to be moved to the left and during extrusion spring A12, piston 6 speed that moves to left further slows down, reel 6 discharges steel ropes 8 and slows down, the descending speed of weight or safety curtain also further slows down thereupon, according to Hook's law, along with compression of spring, dumping force can strengthen gradually.Select elasticity, length, the quantity of spring and adjust its position, can reach different dampings, control is by the descending speed of the weight of rope traction or safety curtain.
