Abstract
The utility model relates to a bolt fastening machine which comprises a tensioning jack and a bolt fastening mechanism, wherein the tensioning jack is composed of a tool screw rod 1, a tensioning nut 2, a piston 3, a cylinder body 4, a nozzle tip A and a nozzle tip B; the bolt fastening mechanism is composed of a cylindrical support leg 5, a bearing 6, an inner hexagonal sleeve nut 9, a work nut 10, a work screw rod 12, a transmission mechanism and a support plate 13; the bearing 6, the inner hexagonal sleeve nut 9 and the work nut 10 are orderly sheathed in the cylindrical support leg 5; the transmission mechanism is composed of a rocking rod 11 and a bevel gear 8. The tool screw rod 1 of the tensioning jack and the work screw rod 12 of the bolt fastening mechanism are connected into a whole by a connecting cylinder 7 through screw threads. The tensioning jack has the advantages of compact structure, simple operation and safe and reliable construction.
Description
The utility model relates to a kind of screw rod stretch-draw jack.
The screw rod stretch-draw jack of existing band window formula spike will reach fastening nut in the spike by instrument when the screw rod stretch-draw anchor, be subjected to the influence of working space, nut is difficult for tightening, to making anchoring unreliable, and working security is poor, in addition, for reaching the enough intensity and the requirement of construction space, the physical dimension of window formula spike must strengthen, and has wasted working space, sometimes even can not satisfy the requirement of construction.
The purpose of this utility model is: provide a kind of by stretch-draw jack and bolted mechanism form, compact conformation, easy and simple to handle, construction safety, the reliable bolted machine of anchoring.
For reaching above-mentioned purpose, bolted machine of the present utility model, comprise stretch-draw jack and bolted mechanism, the stretch-draw jack is by the instrument screw rod, tensioning nut, piston, cylinder body and turnover oil nozzle are formed, bolted mechanism reaches cover bearing within it successively by columnar spike, interior hexagonal sleeve nut, the work nut of outer-hexagonal shape, forwardtransfer signal worm reaches by rocking bar, transmission mechanism that helical gear is formed and support plate are formed, the instrument screw rod of stretch-draw jack is integral by being threaded by connecting cylinder with the forwardtransfer signal worm of bolted mechanism, interior hexagonal sleeve nut and the engagement of helical gear helical teeth, support plate by on the bolt on spike, spike and cylinder body tight fit.
Owing to adopt said structure, the bolted facility of the utility model have compact conformation, easy and simple to handle, construction safety, the reliable advantage of anchoring, are widely used in the screw rod anchoring construction engineering.
Be further described below in conjunction with the architectural feature of drawings and Examples the bolted machine of the utility model.
Accompanying drawing: the structural representation of bolted machine.
Embodiment
A kind of bolted machine, its structure as shown in drawings, this bolted machine comprises stretch-draw jack and bolted mechanism two parts, the stretch-draw jack is by instrument screw rod 1, tensioning nut 2, piston 3, cylinder body 4 and oil nozzle A, B forms, bolted mechanism reaches cover bearing 6 within it successively by columnar spike 5, interior hexagonal sleeve nut 9, the work nut 10 of outer-hexagonal shape, forwardtransfer signal worm 12 reaches by rocking bar 11, transmission mechanism that helical gear 8 is formed and support plate 13 are formed, the instrument screw rod 1 of stretch-draw jack is integral by being threaded by connecting cylinder 7 with the forwardtransfer signal worm 12 of bolted mechanism, interior hexagonal sleeve nut 9 and the engagement of helical gear 8 helical teeth, support plate 13 by on the bolt on spike 5, spike 5 and cylinder body 4 tight fits.
During work, hydraulic oil enters the A hole and goes out to promote piston 3 and tensioning nut 2 and drive instrument bolts 1, connecting cylinder 7, work nut 10, forwardtransfer signal worm 12 together to left movement from the B hole, after forwardtransfer signal worm 12 reaches required stretching force, shake rocking bar 11, rotate together by helical gear 8 drive sleeve nuts 9 and work nut 10, reach the purpose of locking forwardtransfer signal worm 12.
