Abstract
The utility model relates to a device for clamping blowout prevention device conveying sliding blocks, in particular to a blowout prevention device conveying sliding block driving device used for an offshore drilling platform. The blowout prevention device conveying sliding block driving device used for the offshore drilling platform is simple in structure, low in machining and manufacturing difficulty, and flexible in movement in the working process. A pressing plate structure is improved, the height of a pressing plate cylinder is lowered, connection with a rack in a matched mode is removed, and manufacturing precision is decreased. By the guide direction of three pressing plate positioning pins, a tooth plate structure is improved, by utilization of a plane pressing plate with double circular arcs, a friction coefficient is large, slipping is avoided in the moving process, and abrasion between the tooth plates and a guide rail is reduced. Due to the improvements, the clamping mechanism is low in requirements of machining and manufacturing precision, low in machining cost, stable and reliable in clamping, the abrasion between the guide rail and the tooth plates is reduced, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of device of clamping preventer transportation slide block, specifically relates to a kind of drive unit that transports slide block for the offshore drilling platform preventer.
Background technology
At present, the slide block clamping device that generally uses is divided into two kinds and is respectively: hydraulic bolt structure and friction clamp structure.Its shortcoming of hydraulic bolt structure is latch and pin-and-hole status requirement higher, needs to adjust latch and pin-and-hole relative position in the start-up course.Tradition friction clamping device shortcoming is that pressing plate upper cylinder and machine frame hole are had quality of fit, and requirement on machining accuracy is higher, and dental lamina is brave profile of tooth or double side arc shaped, and the clamping poor reliability is easily skidded in the slide block walking process.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model is will provide a kind of to transport slide-driving device for the offshore drilling platform preventer, and it drives by clip claw mechanism and holds guide rail tightly, and then the linear drives cylinder movement is realized the slide block rectilinear motion.
To achieve these goals, the technical scheme that adopts of the utility model is a kind ofly to transport slide-driving device for the offshore drilling platform preventer: it consists of by driving hydraulic cylinder 1, right jaw 2, left jaw 3, hydraulic cylinder mounting base 4, pressing plate 5, guide rail 6 and dental lamina 7; Hydraulic cylinder mounting base 4 is equipment rack, and driving hydraulic cylinder 1, right jaw 2, left jaw 3 are installed on the frame; Right jaw 2 and left jaw 3 lay respectively at the left and right sides that drives hydraulic cylinder; Pressing plate 5 bottoms contact with guide rail 6, and top is for driving hydraulic cylinder 1; In the groove of right jaw 2, left jaw 3 dental lamina 7 is housed respectively.
When the loop is connected, drive hydraulic cylinder 1 rodless cavity oil-feed, descent of piston continues descendingly behind contact pressing plate 5 upper surfaces, drive mounting base 4, right jaw 2, right jaw 3 and move upward, led by pressing plate alignment pin 8 in the descending process of pressing plate, after hydraulic cylinder arrived stroke, the dental lamina 7 that is arranged on right jaw 2, the left jaw 3 contacted with guide rail, holds guide rail tightly by frictional force, then jaw drives cylinder action, realizes the slide block rectilinear motion.
The utility model has the advantage of: 1, simple in structure, processing, manufacture difficulty are low, flexible movements in the course of work.
2, improve pressure plate structure, reduce the pressing plate height of column, cancellation is connected with frame, reduces the accuracy of manufacture.By three place's pressing plate alignment pin guiding.
3, improve dental plate structure, adopt two circular arc planar shaped pressing plates, friction factor is large, avoids skidding in the motion process, has reduced the abrasion of dental lamina and guide rail.
4, by above improvement, the design's clamping device is made requirement on machining accuracy low, cuts down finished cost, and clamping is reliable and stable, has reduced the wearing and tearing of guide rail and dental lamina, extends working time.
