Description
Technical field
The present invention relates to a kind of elevator, specifically assign 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 manual drives worm screw rotate, and worm drive worm gear reducer rotates, and worm gear embedded SMA actuators is 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 equipment, the spiral lift that lifting mode stage uses will be higher in safety requirements, in order to ensure the safety of performing artist, what lifting table designed will be larger, and the elevator used also can be larger, nowadays the elevator diameter that large-scale theater uses will more than 3 meters, stability and safety have also been obtained very large raising.As use in mines elevator, its hoisting depth can reach a few km, and present stage, the hoisting speed of tens meters per second can not meet demand, and so hoisting speed will promote further, reach km on hundreds of per second, and acceleration amplitude also will strengthen.In the course of the work, carry out speed change to reach job requirement, so frequency conversion type elevator also has certain market demand by future to the elevator that some occasions use.
But in the spiral lift of middle-size and small-size bearing load, time in the situation such as electrical fault or power-off, the lifting unit branch of elevator drops suddenly, and then cause producing larger impact dynamics between lifting part and support section, easily cause lifting partial interior impaired, and then reduce the service life of elevator.
Summary of the invention
The object of the present invention is to provide distribution wire pipeline connection arrangement for adjusting height, when avoiding electrical fault, lifting part and the mutual impact of support section, reduce the extent of damage of lifting part, improve the service life of 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, lifting column has rectangular opening, described screw mandrel is provided with rotating cylinder, multiple back-up block is provided with in rotating cylinder, described back-up block is distributed in rotating cylinder inwall along the hand of rotation of screw thread on screw mandrel, groove is had bottom back-up block, rotate in groove and be provided with roller, screw-threaded engagement on roller and described screw mandrel, pilot sleeve is connected with in one end of rotating cylinder, 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, handle is also provided with depression bar, the two ends of depression bar are connected with peg, left snap ring top is provided with hangers, peg passes and is fixedly connected with right snap ring by left snap ring protruding cooperation with hangers, peg is also provided with spring and spring is located between projection and depression bar.In use, screw mandrel rotates and is arranged in lifting column, and under the drive of driver train, screw mandrel rotates in the present invention, and drive the rotating cylinder be positioned on screw mandrel rise or decline, piece-holder then rises or declines by the chuck be connected with rotating cylinder one end, during 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 linear contact lay of screw thread, due to back-up block along the directional spreding of screw thread rotation on screw mandrel on rotating cylinder inwall, therefore when screw mandrel rotates, roller threadingly upper surface moves up, realize whole rotating cylinder on move, the pilot sleeve that the rotating cylinder other end connects is slidably arranged on pilot bar, when rotating cylinder moves up and down, ensure that rotating cylinder can not occur significantly to move radially, and when rising when grips workpiece, pilot sleeve can also regulate the stress balance at rotating cylinder two ends, avoid chuck one end stressed excessive and cause the junction of chuck and rotating cylinder to occur rupturing, and when when power failure or electrical fault, back-up block and wire rod thread close contact, there will not be the possibility that rotating cylinder sharply declines, the setting of roller can play 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, pipe fitting lower end is placed in the border circular areas that formed between left snap ring and right snap ring by chuck, promote depression bar, peg is moved forward, spring is compressed simultaneously, peg engages with hangers through protruding, and left snap ring and right snap ring are connected and fixed, and utilizes the elastic force of spring to act on depression bar respectively with protruding, make peg produce an application force along handle orientations to hangers, and then complete the clamping to pipe fitting, after completing lifting process, depression bar continues to press down by artificial force, peg is separated with hangers, left snap ring is separated by bearing pin automatically with right snap ring, namely the clamping to pipe fitting is unclamped, in clamping process, by spring, the connection between left snap ring and right snap ring is regulated, when lifting unit divides appearance obviously to rock, the spring of compression keeps the application force between depression bar and projection at any time, ensure the dynamics of the clamping of pipe fitting, avoid pipe fitting in the process of rocking, occur the phenomenon glided, avoid pipe fitting and left snap ring simultaneously, relative cliding friction is there is between right snap ring.
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, the area of contact of back-up block and screw mandrel can be had influence on, when adjacent two flight pitch are greater than the width of back-up block, the roller that back-up block and back-up block are arranged can fit with screw thread completely, improves the stability of rotating cylinder when rising or decline.
Described driver train comprises drive motor, and the mouth of drive motor is provided with bevel pinion, and be provided with large bevel gear at the top of described screw mandrel, large bevel gear coordinates with bevel pinion.Drive motor is connected with screw mandrel by large bevel pinion, makes screw mandrel realize the rotation of both forward and reverse directions, ensures that rotating cylinder fast speed on screw mandrel rises or declines.
