The purpose of this utility model will realize by following technical measures: comprise feed nut, feed screw, wedge head, adjusting lever, adjustment assembly, flange hole bayonet lock, mobile jib and secondary bar; Screw is opened at mobile jib middle part, feed screw revolved this screw from top to bottom, and the fixing feed nut in feed screw upper end, wedge head is installed in feed screw lower end, and there is wedge shape sword wedge head lower end, simultaneously, mobile jib one breaks away and is inserted in adjusting lever, and mobile jib opposite side sliding sleeve enters secondary bar or an adjusting lever, and secondary bar or adjusting lever upper end radial aperture are also inserted in from mobile jib both side ends respectively, a flange hole bayonet lock is fixed respectively in the secondary bar of two sides or adjusting lever lower end, and two flange hole bayonet locks of this two side are installed in opposite directions; There is adjustment assembly at adjusting lever middle part, and adjusting assembly is adjustable telescopic device.
Especially, adjust assembly and comprise an internal thread sleeve pipe, adjusting lever therefrom part is two sections, adjusting lever epimere lower end outer rim has annular boss, in internal thread sleeve pipe upper port, along there being annular gear platform, adjusting lever epimere upper end outer rim has screw thread, and internal thread sleeve pipe links together upper and lower section of adjusting lever.
Especially, peg graft in wedge head upper end and feed screw lower end, and screw in lower locking nut in wedge head outer rim radial aperture.
Especially, secondary bar or adjusting lever upper surface axial aperture the upper locking nut that spins.
Advantage of the present utility model and effect: flange to be separated is placed between two flange hole bayonet locks, when the dismounting operation of carrying out pipe flange connection device, only need to just can be by flange separation with spanner rotating nut, performance safety is reliable, simple and convenient practicality, save manpower, can significantly improve by operating speed, reduce workmen's working strength.Easy to carry, use flexibly, manufacture that this is low.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: feed nut 1, feed screw 2, lower locking nut 3, wedge head 4, upper locking nut 5, adjusting lever 6, adjustment assembly 7, flange hole bayonet lock 8, mobile jib 9, secondary bar 10.
The specific embodiment
The utility model principle is, the secondary bar appropriateness that slip on mobile jib upper end is adjusted after length, more convenient and be connected to accurately in corresponding screw, or under given conditions, selects other stand-by card contact.
The utility model comprises: feed nut 1, feed screw 2, wedge head 4, adjusting lever 6, adjustment assembly 7, flange hole bayonet lock 8, mobile jib 9 and secondary bar 10.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, screw is opened at mobile jib 9 middle parts, feed screw 2 revolved this screw from top to bottom, and the fixing feed nut 1 in feed screw 2 upper ends, wedge head 4 is installed in feed screw 2 lower ends, there is wedge shape sword wedge head 4 lower ends, simultaneously, mobile jib 9 one breaks away and is inserted in adjusting lever 6, mobile jib 9 opposite side sliding sleeves enter secondary bar 10 or an adjusting lever 6, be that secondary bar 10 or adjusting lever 6 upper end radial aperture are also inserted in from mobile jib 9 both side ends respectively, a flange hole bayonet lock 8 is fixed respectively in the secondary bar 10 of two sides or adjusting lever 6 lower ends, and two flange hole bayonet locks 8 of this two side are installed in opposite directions; There is the assembly 7 of adjustment at adjusting lever 6 middle parts, and adjusting assembly 7 is adjustable telescopic device.
In aforementioned, adjust assembly 7 and comprise an internal thread sleeve pipe, adjusting lever 6 therefrom part is two sections, adjusting lever 6 epimere lower end outer rims have annular boss, in internal thread sleeve pipe upper port, there is annular gear platform on edge, adjusting lever 6 epimere upper end outer rims have screw thread, and internal thread sleeve pipe links together upper and lower section of adjusting lever 6.
In aforementioned, pegging graft in wedge head 4 upper ends and feed screw 2 lower ends, and screws in lower locking nut 3 in wedge head 4 outer rim radial aperture.
In aforementioned, secondary bar 10 or adjusting lever 6 upper surface axial aperture the upper locking nut 5 that spins.
In the utility model, feed nut 1 is connected with feed screw 2 for transmitting the torsion of spanner effect; The active force that the torsion that feed screw 2 produces feed nut 1 produces forward by mobile jib 9; Lower locking nut 3 stops the slippage from feed screw 2 of wedge head 4, and does not affect the rotation of feed screw 2 in wedge head 4; Wedge head 4 utilizes its sharp-pointed shape between flange and valve, to strut, and is convenient to change the upkeep operations such as mat; Upper locking nut 5 is according to distance between the width adjustment adjusting lever 6 between valve and flange and secondary bar 10, and precession is locked; Adjusting lever 6, when flange hole and valve corresponding aperture generation dislocation, utilizes the adjustment assembly on adjusting lever to rotate the screw that can draw high dislocation; Adjust assembly 7 for the length of adjusting lever.Mobile jib 9 is for the positioning action between adjusting lever 6 and secondary bar 10, and feed screw 2 produces rotation motion forward by the screw on mobile jib 9.Flange hole bayonet lock 8 is selected according to the size in flange aperture, and forms being connected between adjusting lever 6, secondary bar 10 and flange.
During the utility model work, by the bolt complete removal on valve and adpting flange; Adjusting lever 6 and secondary bar 10 are arranged on mobile jib 9, and select suitable flange hole connecting pin to install, and by the locking nut screwing of the upper locking nut of adjusting lever 65 and the secondary bar of corresponding opposite side 10 upper ends; And feed screw 2 is screwed in to mobile jib 9, and in mobile jib 9 lower ends, wedge head 4 is installed; The feed nut 1 of rotation mobile jib 9 upper ends, feed screw 2 rotarily drives wedge head 4 and advances, and, until there is the width of operation in gap between expanded flange; After operation, can utilize feed screw 2 to exit wedge head 4, and connecting bolt on flange is installed, fulfil assignment; If there is wrong hole phenomenon in flange, can utilize and regulate assembly 7 to adjust wrong hole phenomenon, can normal mounting position until reach connecting bolt.
