Description
Technical field
The present invention relates to a kind of elevator, specifically assignment wiring conduit joint arrangement for adjusting height.
Background technology
Traditional spiral lift is generally made up of parts such as worm and gear, casing, bearing, leading screws; Principle of work is: motor or the rotation of manual drives worm screw, and the rotation of worm drive worm gear reducer, worm gear inner chamber is processed as negative thread, drives leading screw to move up and down, and because there is worm and gear inside, the deceleration effort of leading screw, reaches the effect of amplifying thrust.And spiral lift is very wide as its use field of jacking equipment in a kind of modern times, the development of screw-threaded shaft elevator is also very fast, be not difficult to draw the developing direction of following elevator, its medium velocity, speed change and safety performance are main points wherein, the importance of safety is all extremely important on various device, the spiral lift that lifting mode stage uses will be higher in safety requirements, in order to guarantee performing artist's safety, what lifting table designed will be larger, and the elevator using also can be larger, nowadays the elevator diameter that large-scale arenas uses will exceed 3 meters, stability and safety are also greatly improved.As use in mines elevator, its hoisting depth can reach several kms, and present stage, the hoisting speed of tens meters per second can not meet demand, and hoisting speed will further promote so, reach km on hundreds of per second, and acceleration amplitude also will strengthen.The elevator that some occasions are used in the course of the work, carry out speed change and reach job requirement, and frequency conversion type elevator also will have certain market demand in future so.
But in the spiral lift of middle-size and small-size bearing load, in the situation such as electrical fault or power-off time, the lifting unit branch of elevator drops suddenly, and then cause between lifting part and support section producing larger impact dynamics, easily cause lifting partial interior impaired, and then the service life of having reduced elevator.
Summary of the invention
The object of the present invention is to provide distribution wire pipeline connection arrangement for adjusting height, the mutual impact of lifting part and support section while avoiding electrical fault, the extent of damage of reduction lifting part, the service life of improving jacking system.
Object of the present invention is achieved through the following technical solutions:
Distribution wire pipeline connection arrangement for adjusting height, comprise lifting column, screw mandrel and pilot bar are installed in described lifting column, the upper end of described screw mandrel is connected with driver train, on lifting column, have rectangular opening, on described screw mandrel, rotating cylinder is installed, in rotating cylinder, be provided with multiple back-up blocks, described back-up block is distributed in rotating cylinder inwall along the hand of rotation of screw thread on screw mandrel, have groove in back-up block bottom, in groove, rotate and be provided with roller, screw-threaded engagement on roller and described screw mandrel, one end at rotating cylinder is connected with pilot sleeve, pilot sleeve is slidably arranged on pilot bar, the other end of rotating cylinder is also connected with chuck, chuck comprises left snap ring and right snap ring, left snap ring is connected with right snap ring by bearing pin, on right snap ring top, handle is installed, the both sides of handle are provided with projection, depression bar is also installed on handle, the two ends of depression bar are connected with peg, left snap ring top is provided with hangers, peg coordinates with hangers left snap ring is fixedly connected with right snap ring through projection, on peg, be also provided with spring and spring is located between projection and depression bar.In use, screw mandrel rotates and is arranged in lifting column in the present invention, and under the drive of driver train, screw mandrel rotates, and drives the rotating cylinder being positioned on screw mandrel to rise or decline, and the chuck being connected with rotating cylinder one end rises piece-holder or decline, when rising, screw thread on screw mandrel is connected with the back-up block on rotating cylinder inwall, be positioned at the roller of groove and the upper surface line of screw thread contacts, because back-up block is distributed on rotating cylinder inwall along the direction of screw thread rotation on screw mandrel, therefore when screw mandrel rotates, roller moves up along screw thread upper surface, realize whole rotating cylinder on move, the pilot sleeve that the rotating cylinder other end connects is slidably arranged on pilot bar, in the time that rotating cylinder moves up and down, guarantee that rotating cylinder can not occur significantly to move radially, and in the time that chuck holding workpiece rises, pilot sleeve can also regulate the stress balance at rotating cylinder two ends, avoid chuck one end stressed excessive and cause chuck and rotating cylinder junction occur fracture, and when when power failure or electrical fault, back-up block and wire rod thread close contact, the possibility that there will not be rotating cylinder sharply to decline, the setting of roller can be played buffer action to the instantaneous impulsive force between back-up block and screw thread, greatly reduce the extent of damage of rotating cylinder, improve the working stability performance of elevator, chuck is placed in end, pipe fitting lower end in the border circular areas forming between left snap ring and right snap ring, promote depression bar, peg is moved forward, spring is compressed simultaneously, peg engages with hangers through projection, and left snap ring and right snap ring are connected and fixed, and utilizes the elastic force of spring to act on respectively depression bar and projection, make peg produce an application force along handle orientations to hangers, and then complete the clamping to pipe fitting, when completing after lifting process, manually firmly depression bar is continued to press down, peg and hangers are separated, left snap ring separates by bearing pin automatically with right snap ring, unclamp the clamping to pipe fitting, in clamping process, by spring, being connected between left snap ring and right snap ring regulated, in the time that lifting unit divides appearance obviously to rock, the spring of compression keeps at any time to the application force between depression bar and projection, guarantee the dynamics of the clamping of pipe fitting, avoid pipe fitting in the process of rocking, to occur the phenomenon gliding, avoid pipe fitting and left snap ring simultaneously, between right snap ring, there is relative cliding friction.
The spacing of two adjacent described screw threads is greater than the thickness of back-up block.The spacing size of two adjacent screw threads, can have influence on the area of contact of back-up block and screw mandrel, in the time that adjacent two flight pitch are greater than the width of back-up block, the roller that arranges on back-up block and back-up block can be completely and screw thread laminating, improved rotating cylinder rising or stability when decline.
