The construction method disclosed by the invention has the advantages of accurate rack centring, low construction cost, and simple and safe operation.
Description
Technical field
The present invention relates to a kind of construction method improving steel tube punching machine frame accuracy of alignment, belong to metallurgical machinery equipment installation field.
Technical background
Steel tube punching machine is the key equipment of seamless steel tube production chain, and punch installation engineering quality directly affects the product quality of seamless steel pipe.In punch equipment is in the past installed, adopt integral hoisting method, that is: it is right first to be organized on assembly platform by punch memorial archway, then by group to good punch integral hoisting to installation site, finally adjust installation.This method need be installed with large automobile crane or crawler crane, there is the reasons such as construction site is narrow, factory building roof, job site is closed, inadequate, the large-scale crane radius of gyration of overhead traveling crane maximum lift heavy amount is limited, causes equipment hoisting and adjustment difficulty.Limit by large-scale crane radius of gyration, need the factory roof that close remove, equipment hoisting potential safety hazard is comparatively large, and final frame accuracy of alignment is low, the crane used time is many, waste time and energy.
Summary of the invention
The object of this invention is to provide that a kind of frame centering is accurate, operating expenses is low, the construction method of safe raising steel tube punching machine frame accuracy of alignment simple to operate.
The object of the invention is by realize with under type:
First left and right for punch base is lifted on the basis that equipment is installed, left and right base is relative, between reserve frame is connected T-shaped key size (centre-to-centre spacing+key high size) assembling space with internal part, then respectively arranged on left and right sides frame is assembled into the inner side of base, arranged on left and right sides frame is pre-assembled with lower pressuring upper device, upper screwdown gear, changing rig and crosshead bolt respectively, measure adjustment equipment absolute altitude, levelness, the depth of parallelism and perpendicularity; Be placed between basis, both sides that the left and right base of punch and equipment installs by symmetrical respectively for four hydraulic jack again, horizontally disposed two hydraulic jack in every side, four hydraulic jack are by the action of a hydraulic control device control synchronization; Theodolite is adopted to determine the Precise Installation Position of left and right base, light barrier transmitter is set, two grating sensing lines are transmitted into respectively the Precise Installation Position of the left and right base that theodolite is determined, be separately fixed on arranged on left and right sides base inside edge by two cover grating displacement sensors, the holding wire of grating displacement sensor is connected with the breaker of hydraulic control device; Power to hydraulic control device, four hydraulic jack start to do extend action simultaneously, promotion base and the frame be connected with base move to punch equipment center simultaneously, when grating sensor with base motions to grating sensing line position time, the breaker open circuit immediately that sensor connects, power-off, causes hydraulic control device locking, hydraulic jack stop motion, completes the left and right frame of punch and synchronously passes centering installation.
Advantage of the present invention is:
(1) one drags four synchronous hydra-ulic jacks propulsive forces to utilize hydraulic means to control, and realizes synchronously advancing;
(2) grating displacement sensor is by the refraction principle of light, and connecting breaker makes power supply automatically close, thus fast braking hydraulic means, can accurately stop in the horizontal direction;
(3) frame centering is accurate, improves installation accuracy, reduces operating expenses, simple to operate safe and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of punch;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is hydraulic control device control principle drawing.
Detailed description of the invention
With reference to accompanying drawing, in φ 159 mandrel mill-rolled steel pipe production line project that Baogang is seamless, punch is installed as example, and present invention is described:
Punch be arranged in factory building BC across 12 ~ 13 lines between, on 13 meters of reinforced concrete platforms.Punch body equipment manufactures and designs for western mark group of Germany (SMS group).Punch main body frame heavily about 180t, the heavy 260000kg of main frame, appearance and size is 4710mm × 3624mm × 7244mm.Punch equipment is loose mail arrival, carries out Assembling.
1, preparation before construction method: first install left and right two bases 5,4 of punch, reserve frame and be connected T-shaped key size (centre-to-centre spacing+key high size) with internal part.Then respectively arranged on left and right sides frame 3,2 is assembled into the inner side of base, arranged on left and right sides frame is pre-assembled with bolt with lower pressuring upper device 1, upper screwdown gear 6, changing rig 7 and crosshead 8 respectively, reserve left and right frame equally and coordinate with internal unit the size that T-shaped key is high, measure adjustment equipment absolute altitude, levelness, the depth of parallelism and perpendicularity.
2, centering location and installation construction method:
(1) be placed between basis, both sides 9,10 that the left and right base 5,4 of punch and equipment installs by symmetrical respectively for four hydraulic jack 11, horizontally disposed two hydraulic jack in every side, four hydraulic jack are by the action of a hydraulic control device control synchronization;
(2) theodolite is adopted to determine the Precise Installation Position of left and right base 5,4, light barrier transmitter 12 is set, two grating sensing lines 13,14 are transmitted into respectively the Precise Installation Position of the left and right base that theodolite is determined, be separately fixed on arranged on left and right sides base 5,4 inside edge by two cover grating displacement sensors 15,16, the holding wire of grating displacement sensor 15,16 is connected with the breaker 18 of hydraulic control device 19;
(3) power supply 17 powers to hydraulic control device 19, four hydraulic jack 11 start to do extend action simultaneously, promotion base and the frame be connected with base move to punch equipment center simultaneously, when grating sensor with base motions to grating sensing line position time, the breaker open circuit immediately that sensor connects, power-off, causes hydraulic control device locking, hydraulic jack stop motion, completes the left and right frame of punch and synchronously passes centering installation.
Facts have proved and utilize the method, novel, quick, reliable, the accuracy of alignment of steel tube punching machine frame can greatly be improved, shorten the construction period, increase work efficiency, achieve good effect.
