Description
Technical field
The present invention relates to a kind of elevator, specifically refer to a kind of clamping device of electrical conduits elevator.
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.
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; In pipe fitting lifting process, return as required and vertical lifting is carried out to pipe fitting, by the holding device of lifting part, pipe fitting is clamped, when being elevated, loosening easily appears in general holding device, can cause pipe fitting glide and in downslide process outer surface of pipe fittings can rub with holding device, cause pipe fitting impaired.
Summary of the invention
The object of the present invention is to provide a kind of clamping device of electrical conduits elevator, avoid pipe fitting surprisingly loosen in lifting process and cause pipe fitting to glide, reduce the pipe fitting extent of damage.
Object of the present invention is achieved through the following technical solutions:
A kind of clamping device of electrical conduits elevator, comprise left snap ring and right snap ring, described left snap ring is connected with right snap ring by bearing pin, be provided with handle on described right snap ring top, the both sides of handle are provided with projection, and handle is also provided with depression bar, the two ends of described depression bar are connected with peg, described left snap ring top is provided with hangers, and left snap ring was fixedly connected with right snap ring through protruding to coordinate with hangers by peg, peg is also provided with spring and spring is located between projection and depression bar.The present invention in use, pipe fitting lower end is placed in the border circular areas formed between left snap ring and right snap ring, promote depression bar, peg is moved forward, and spring is compressed simultaneously, and peg engages with hangers through protruding, left snap ring and right snap ring are connected and fixed, utilize 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, reduce the extent of damage of pipe fitting.
The circle ring inner wall that described left snap ring and right snap ring are formed is provided with multiple major arc groove, and described major arc grove shaped circumferential array distribution is at circle ring inner wall.Faced by the smooth circular clamp that left and right snap ring is formed, the clamping dynamics of pipe fitting is less, and pipe fitting easily glides in lifting process; The multiple major arc grooves arranged are compared with general deep-slotted chip breaker, square groove, increase annulus local and the area of contact of pipe fitting appearance, also avoid pipe fitting appearance by the groove edge scratch of groove while improving the Clamping force of annulus local to pipe fitting appearance, improve the clamping stability of left and right snap ring in lifting process.
Described right snap ring is also provided with anticreep plate, and anticreep plate and right snap ring hinged.During lifting, pipe fitting itself has certain weight, particularly when pipe fitting starts clamping or terminates clamping, also need manually to help pipe fitting, increase the work capacity of staff, the anticreep plate of setting and the bottom-hinged of right snap ring, can rotate it, when clamping pipe fitting, anticreep plate is rotated the bottom to left and right snap ring, and anticreep plate provides certain support for pipe fitting, facilitates the fast clamp of pipe fitting; When terminating the clamping to pipe fitting, pipe fitting is held by anticreep plate, eliminates the artificial support to pipe fitting, reduces the working strength of workman.
Described handle by connecting panel and right snap ring hinged, described connecting panel is fixed on right snap ring.Handle and right snap ring hinged, during clamping, handle can move up and down, and when handle moves down, can increase the application force of peg to hangers, improves left and right snap ring to the clamping dynamics of pipe fitting; When handle moves up, the application force of peg to hangers can be reduced at the end of clamping, shorten the operating time, increase work efficiency.
Described spring is torsion spring.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the clamping device of a kind of electrical conduits elevator of the present invention, 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, ensures the dynamics of the clamping of pipe fitting, avoids pipe fitting in the process of rocking, occur the phenomenon glided, avoid pipe fitting to occur relative cliding friction with between left snap ring, right snap ring simultaneously, reduce the extent of damage of pipe fitting;
2, the clamping device of a kind of electrical conduits elevator of the present invention, when clamping pipe fitting, anticreep plate is rotated the bottom to left and right snap ring, and anticreep plate provides certain support for pipe fitting, facilitates the fast clamp of pipe fitting; When terminating the clamping to pipe fitting, pipe fitting is held by anticreep plate, eliminates the artificial support to pipe fitting, reduces the working strength of workman;
3, the clamping device of a kind of electrical conduits elevator of the present invention, handle and right snap ring hinged, during clamping, handle can move up and down, and when handle moves down, can increase the application force of peg to hangers, improves left and right snap ring to the clamping dynamics of pipe fitting; When handle moves up, the application force of peg to hangers can be reduced at the end of clamping, shorten the operating time, increase work efficiency.
