Abstract
The invention relates to a tensioner ring tightening method and a tensioner ring tightening mechanism. A tensioner ring is formed by splicing 3 to 6 sub-tensioner rings with embedding seam allowances, and reducing wedge sockets are reserved at the two ends of each splicing joint of the sub-tensioner rings. The tensioner ring tightening method of the invention comprises the following steps of: performing pressurization with a single-head oil cylinder, pushing and expanding the reducing wedge sockets at the splicing joints of the sub-tensioner rings with the tensioner ring tightening mechanism, simultaneously compressing a sealing rubber gasket, and inwards pushing reducing wedges in the reducing wedge sockets with hands, namely, decompressing the oil cylinder after inwards tightly inserting the reducing wedges and generating high circumferential forces by the tensioner ring and the reducing wedges per se to keep a compressed and sealing state of the sealing rubber gasket between a steel tube and the tensioner ring. The tensioner ring is tightened by the tensioner ring tightening method, which is labor-saving, convenient and of no noise.
Description
Technical field:
The present invention relates to the pipeline pressure technical field of measurement and test, be meant the method and the tensioner ring tightening mechanism of the tensioner ring tightening that uses in the pressure testing of large-scale pipeline especially.
Background technology:
At present, domestic water supply and drainage pipeline pressure test method is to adopt whether seepage of pipe joint is measured in pipe joint weld sealing pressure testing.Specific purpose tool as Chinese patent CN 200910136351.4 pipeline pressure test methods and device and beating variable diameter wedge, its concrete grammar is to place the O-ring seal that a cylindrical has annular groove at the pipe joint weld, the O-ring seal tensioner ring inner support that has the tensioner rings splicing in a plurality of minutes of inlaying the rim of the mouth, locate with screw, then, (variable diameter wedge front end circular arc radius r is little with a variable diameter wedge, arc radius R is big in the rear end, differ 6～12mm) and insert the opening part that divides the tensioner ring splicing, manpower uses the double direction impulse hammering to beat variable diameter wedge, wedging tensioner ring inner support O-ring seal, and huge circumferential force is compressed O-ring seal between tensioner ring and water conveyance steel tube, make the middle annular groove of pipe joint weld and O-ring seal outside surface become a strong sealing space, open the drain tap exhaust, the beginning water-filling, arranged gas after, close drain tap, continue water-filling and pressurization, reach the authorised pressure value after, close inlet valve, it is that pressure measurement is qualified that the confining pressure time reaches predetermined value, has promptly detected the bearing capacity at pipe joint place.After pressure testing detects, remove pressure testing device.Its method is, tensioner ring has the branch tensioner ring splicing of inlaying the rim of the mouth by three～six and forms, only leaves a variable diameter wedge socket in minute tensioner ring splicing place, and variable diameter wedge is inserted socket, and manpower uses the ram hammer beating variable diameter wedge to get final product the stretching tensioner ring.
Shortcoming: when manpower used the ram hammer beating variable diameter wedge, along with the insertion of variable diameter wedge, the arc radius of variable diameter wedge became greatly, and the bounce that variable diameter wedge is subjected to tensioner ring is just big more, just requires great effort more with the ram hammer beating variable diameter wedge, and hit noise is big, the labour intensity height.
Summary of the invention:
The method and the tensioner ring tightening mechanism that the purpose of this invention is to provide a kind of tensioner ring tightening.Tensioner ring has the branch tensioner ring splicing of inlaying the rim of the mouth by three～six and forms, and only leaves a variable diameter wedge socket in minute tensioner ring splicing place.The tensioner ring tightening method is that original " manpower with the method for ram hammer beating variable diameter wedge with tensioner ring tightening " changed into singly lifting one's head the oil cylinder pushing tow tightening mechanism that pressurizes, support big variable diameter wedge socket, O-ring seal is compressed simultaneously, afterwards, advance to be placed on the variable diameter wedge of variable diameter wedge spigot with hand push, inwardly be seated, oil cylinder decompression then, the huge circumferential force that utilizes tensioner ring and variable diameter wedge self to form, keep the compression seal state of O-ring seal between steel pipe and tensioner ring, wherein, tightening mechanism is fixed on the branch tensioner ring on variable diameter wedge spigot both sides by the thrust axillare.During dismounting, in the basic Chu of the big variable diameter wedge socket of oil cylinder pressurization support,, will singly lift one's head the oil cylinder off-load after zero-bit, from tensioner ring tightening mechanism, take out again and singly lift one's head oil cylinder and tightening mechanism with pulling out the variable diameter wedge that is placed in the variable diameter wedge socket.
Realize the tensioner ring tightening mechanism of tensioner ring tightening method, tensioner ring has the branch tensioner ring splicing of inlaying the rim of the mouth by three～six and forms, only leave a variable diameter wedge socket in minute tensioner ring splicing place, tensioner ring tightening mechanism, by tightening mechanism, two thrust axillares that have a thrust axis and one singly lift one's head oil cylinder and form, tightening mechanism comprises a pair of lifting jack slippage pedestal, two slippage mainboards, two gussets and floor, wherein, lifting jack slippage pedestal contains slippage front and back seat, a side of seat respectively is provided with the slide block of protrusion before and after the slippage, the middle inside symmetry of two slippage mainboards has the matrix gathering sill, after a floor is welded in the bottom at middle part between the two slippage mainboards, with two lifting jack slippage pedestals, insert in the matrix gathering sill of two slippage mainboards from left-right symmetric, then gusset is placed on the two ends of two slippage mainboards, be integral with bolt, at last its fastening is placed on the axle of thrust axillare, constitutes a complete tensioner ring tightening mechanism.
The present invention is the further innovation to tensioner ring tightening method and apparatus in the pipeline pressure test method, and advantage is laborsaving, convenient, noiseless.
