Abstract

The invention discloses a spiral lifting mechanism. The spiral lifting mechanism comprises a lifting column, a screw rod and a guide rod are arranged inside the lifting column, the upper end of the screw rod is connected with a driving mechanism, a rectangular hole is formed in the lifting column, a rotating barrel is arranged on the screw rod, a plurality of supporting blocks are arranged inside the rotating barrel and distributed on the inner wall of the rotating barrel in the rotating direction of a thread on the screw rod, a groove is formed in the bottom of each supporting block, an idler wheel is rotationally arranged inside each groove, the idler wheels are meshed with the thread of the screw rod, one end of the rotating barrel is connected with a guide sleeve arranged on the guide rod in a sliding mode, and the other end of the rotating barrel is further connected with a chuck penetrating through the rectangular hole. When the spiral lifting mechanism works, stress at the two ends of the rotating barrel can be balanced by being regulated by the guide sleeve, and it is avoided that stress at one end of the chuck is overlarge and therefore the joint of the chuck and the rotating barrel is fractured; when a motor breaks down, the idler wheels can buffer instant impact force between the supporting blocks and the thread, the degree of damage to the rotating barrel is lowered, and stability of the spiral lifting mechanism is improved.

Description

Spiral lifting mechanism

Technical field

The present invention relates to a kind of elevator, specifically refer to spiral lifting mechanism.

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 spiral lifting mechanism, 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:

Spiral lifting mechanism, 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 and chuck passes rectangular opening.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.

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.

Described driver train comprises drive motor, on the mouth of drive motor, bevel pinion is installed, and at the top of described screw mandrel, large bevel gear is installed, and big gear wheel coordinates with miniature gears.Drive motor is connected with screw mandrel by large bevel pinion, makes screw mandrel realize the rotation of both forward and reverse directions, guarantees that rotating cylinder fast speed on screw mandrel rises or declines.

Also be provided with travel switch in end, the upper and lower two ends of described lifting column, described travel switch is connected with drive motor, and described chuck is between two travel switches.For preventing that rotating cylinder from excessively rising or declining; be provided with travel switch at the upper and lower two ends of lifting column; travel switch is connected with drive motor; in the time that rising or drop to assigned address, rotating cylinder contacts with travel switch; travel switch control drive motor stops operating; and then move in the continuation of the cylinder that stops the rotation, protect well rotating cylinder, avoid it impaired.

The rotation direction of described roller is consistent with the hand of rotation of screw thread.The rotation direction of the roller that is positioned at groove in the time that rotating cylinder rises or decline has multiple, such as roller rotation direction and screw thread rotation direction shape have a certain degree etc., with as preferably, the rotation direction of roller is arranged on screw mandrel to the hand of rotation of screw thread consistent, can improve rising or the descending speed of rotating cylinder, improve raw lifting efficiency.

The present invention compared with prior art, has following advantage and beneficial effect:
