Description

Roll changing equipment system of straightener
Technical Field
The utility model relates to a combined type frame straightening machine type, an automatic roll changing vehicle and a roll changing integrated frame with an integral structure form, wherein the roll changing integrated frame is matched with a maintenance base for use under the process condition of roll changing of a transverse track.
Background
The section steel straightening production line adopting the combined type frame straightening machine type (Combined rack type) adopts an automatic roll changing machine integral group roll changing process for matching the productivity of a rolling line, reducing the roll changing operation time and improving the roll changing efficiency.
The combined straightening machine frame is mainly formed by combining an operation side frame, a transmission side frame and a front frame and a rear frame for carrying the vertical rolls, and the frames form a closed state; except that the operation side frame can move along a longitudinal moving track which is in the same direction as the axis line of the straightening roll, the rest parts of the combined frame are relatively fixed in a corresponding connection mode, and the frame is required to be opened to detach or load the straightening roll during roll changing. When in straightening operation, the straightening roller is arranged in the middle of the operating side frame and the transmission side frame; when the roll changing operation is performed, after the fastening condition of the straightening roll system and the operation side stand is unlocked, the operation side stand carries the straightening roll to move on a longitudinal track along the axial direction of the straightening roll under the driving of a hydraulic cylinder; after reaching the roll changing position, a condition is formed that the straightening roll can be radially moved out.
Under the process condition of automatic roll changing and roll changing in groups, typical process arrangement and equipment configuration modes of a straightening operation area are that a transverse moving track is arranged in parallel along a straightening center line at a certain distance from a straightener and used for running of the automatic roll changing and roll changing; on the traversing rails, an automatic roll changing vehicle is arranged on each of the inlet and outlet direction rails of the straightener.
Before straightening operation, the automatic roll changing vehicle stays on each waiting position; wherein one automatic roll changing vehicle loads a new straightening roll. When the roll changing operation is performed, the combined type stand is opened, the operation side stand carries old straightening rolls to a roll changing position, the empty automatic roll changing vehicle enters a roll changing area of the stand and then stays on the roll changing position of the transverse moving track, and after the old straightening rolls are moved onto the automatic roll changing vehicle from the operation side stand through a straightening roll carrying procedure, the automatic roll changing vehicle carrying the old straightening rolls moves out of the roll changing area of the combined type straightener; the automatic roll changing vehicle carrying the group of new straightening rolls enters the roll changing area of the frame and then stays on the roll changing position of the transverse moving track, and after the new straightening rolls move to the frame at the operation side through the procedure of the carrying party of the straightening rolls, the unloaded automatic roll changing vehicle exits the roll changing area of the combined frame. The operating side frame is moved to a roll changing position, and an empty automatic roll changing vehicle 1 arranged at the left side of the straightener enters a roll changing position of a transverse moving track in the frame; the automatic roll changing truck 2 loaded with the new straightening rolls is in a waiting position on the traversing rail.
The combined frame straightener transverse track automatic roll changing machine group integral roll changing process is an automatic process for automatically disassembling and assembling straightening rolls under a three-dimensional coordinate system. In the automatic roll changing process, the old straightening roll carried on the operating side frame is transferred to the automatic roll changing vehicle, the new straightening roll carried on the automatic roll changing vehicle is transferred to the operating side frame, the functional structure of the carrying straightening roll is a cantilever type roll shaft no matter whether the operating side frame or the automatic roll changing vehicle is adopted, the cantilever type roll shaft in a short and small half shaft form is inserted into a central hole of the straightening roll in an exchange mode, one pull claw locks the straightening roll, and the other pull claw releases the straightening roll; in each stage of the roll changing process, the operating side frame and the automatic roll changing vehicle have the setting requirement of the instant position. In the roll changing integrated frame on the automatic roll changing vehicle, the axial lead of the hanging straightening roll is between the axial lead of the roll shaft of the hanging straightening roll and the axial lead of the roll shaft of the hanging straightening roll on the bearing seat of the operating side frame, so that the requirements on the axial dimension position precision and the coaxiality position are higher; the automatic carrier vehicle carrying the roll changing integrated frame is used in the function structure of automatic assembly. The correlation degree between the geometric dimension and the precision requirement of the movement position is high. In order to solve the problems of the size and the position precision in the roll changing process of the automatic roll changing machine, the important point is to solve the problems of the structure, the performance and the parametrism of the automatic roll changing machine which are matched with the straightener serving as a reference standard; the existing equipment architecture, body structure and connection mode are analyzed to propose new solutions.
The automatic roll changing machine system mainly comprises a lower machine system with functions of moving on a transverse track, positioning a car body and the like and an upper machine system carrying straightening rolls. The upper equipment system is generally a roll changing integrated frame for integrally changing the straightening roll; the lower equipment hierarchy body equipment is typically a coupling system between the automated carrier vehicle and the upper lower equipment therein.
The number and the position relation of the roll shafts of the hanging straightening rolls on the roll changing integrated frame are determined according to the structural size of the straightener and the set vertical roll changing position of the straightening rolls.
According to the condition of the process field, the application mode of the roll changing integrated frame and the connection mode of the roll changing integrated frame and the carrier vehicle are determined by the preparation operation mode. The roll changing integrated frame and the carrier vehicle are connected in a simple direct welding and positioning quick connecting system.
The roll changing integrated frame is a key device in the automatic roll changing vehicle, and the self structural form and the connection mode with the automatic carrier vehicle have great influence on the application mode of the automatic roll changing vehicle and the performance required by roll changing operation. In the existing combined type frame straightener production line, an automatic roll changing vehicle basically fixes a roll changing integrated frame in a mode of direct connection or welding of fasteners; as shown in fig. 2, the main technical features thereof can be reflected by the following aspects:
1) Structural system
In the structural system of the roll changing integrated frame, a roll shaft of a hanging straightening roll is arranged in a modularized roll box unit; and then a plurality of modularized roll box units are assembled into a roll changing integrated frame in the frame body.
2) Roller box unit connection mode
The bottom surface of the roller box unit and the combining surface of the frame body are axially positioned by adopting a flat key in the direction vertical to the roller shaft, and are connected and fastened in the up-down direction by a bolt component; meanwhile, in order to coordinate the requirements of the dimension and the position of the central line of the same row of roller shafts and the central line of the upper row of roller shafts and the central line of the lower row of roller shafts in the height direction, a gasket group is adopted between the joint surface of each roller box unit and the frame body for adjustment.
3) Frame and its connection mode with car body
The frame body is a welding workpiece. The matching surfaces used on the bottom surfaces of the upper roller box unit and the lower roller box unit in the frame body structure are in a concave shape which is discontinuously distributed.
The frame body and the vehicle body of the carrier vehicle are directly welded into a whole.
4) Adjustment mode
In order to coordinate the levelness of the automatic carrier vehicle, the bearing seats of the wheel sets positioned at the lower part of the vehicle body are assembled by using the gasket sets to adjust the height direction.
The automatic roller changing vehicle with the machine type structure has the following problems
The arrangement of intermediate links in the roll box brings adverse effects in terms of structure, function and performance
The roll shaft used for hanging the straightening roll in the integrated frame assembled by the roll box units is a basic function piece for roll changing integration.
The requirements of dimensional accuracy, parallelism, coaxiality position accuracy and the like among the roll shafts in the roll changing process not only need the guarantee of manufacturing size and form tolerance of the roll shafts in the unit roll box, but also need the guarantee of the contour size and form tolerance of the connection of the roll box unit and the frame body, the contour size and form tolerance of the frame body and the quality assurance of the connection assembly; the various factors have a great influence on the exchange function of the straightening roll carrier.
As an intermediate link, the modular design of the roller box unit brings local convenience in terms of manufacturing, but the intermediate link is arranged to complicate the structure of the roller changing integrated frame, thereby bringing about equipment assembly, complexity of adjustment links and adverse factors in field use and maintenance. The roller box unit is arranged to enable the performance of the roller shaft to be adversely affected from the requirements of functions and performances of the roller replacing integrated frame.
2) Adverse effects of frame Structure
The roll changing process takes the center line of a roll system of the straightener as a reference; all the center lines of the lower straightening rollers are on the same horizontal line, so that the joint surfaces of the roller box units for installing the lower rollers are on the same horizontal plane in the integrated frame. However, as the matching surfaces used on the bottom surfaces of the upper roller box unit and the lower roller box unit in the frame body structure are in concave shapes which are discontinuously distributed, the roller box unit and the frame body connecting structure adopt a radial assembly mode; thereby bringing complexity of the processing and manufacturing process and influencing the consistency of the center high dimension of the matching surface. The method that all the roller box units are adjusted by adopting the gasket groups directly reflects the inconsistent and non-horizontal phenomena of the central high dimension of the frame body, and indirectly reflects the unmatched state of the direct welding mode of the frame body and the carrier body and the roller changing performance requirement.
Secondly, because the roller box unit and the frame body are axially positioned by adopting the flat key, the positioning mode simultaneously controls the axial position of the roller shaft and the parallelism between the roller shafts. From the single roller box positioning angle, the axial lead of the roller shaft of the roller box can be ensured to be vertical to the vehicle body; however, because the concave state of discontinuous dispersion of the matching surfaces of the frame bodies influences the key groove processing adverse factors, the accuracy requirements of the same axial position of the roll shaft and the parallelism between the roll shafts are difficult to realize.
In addition, the abrupt change of the structural section of the frame body has a certain adverse effect on the deformation control of the welding workpiece.
3) The connection mode of the frame body structure and the vehicle body limits the application range of the integrated frame function
Because the composite gravity center of the roll changing integrated frame carried on the upper part of the automatic roll changing vehicle is outside the dangerous overturning edge of the outline of the frame body, the roll changing integrated frame is lack of the dangerous overturning resistance, and can only be directly and fixedly connected with the vehicle body of the carrier vehicle into a whole, the composite gravity center is formed in the whole range of the automatic carrier vehicle, and the anti-overturning stability in the transverse moving track of the automatic carrier vehicle is maintained, so that the roll changing integrated frame cannot have the functional condition of leaving the automatic carrier vehicle to perform independent operation; the automatic carrier vehicle can only detach and load the straightening rollers at the parking position on the transverse moving track, so that the roller changing operation area and the roller preparing operation area are greatly limited.
And secondly, the frame body of the automatic carrier vehicle is directly and fixedly connected with the vehicle body into a whole, the connection relationship is seemingly simple, but the influence of adverse factors such as the processing difficulty of large-size structural equipment and the deformation of the frame body and the vehicle body is brought.
The automatic roller changing machine has the advantages that the machine type system is complex, the structural design is unreasonable, the assembly and adjustment links are multiple, the process application mode and the site condition are limited, and the like; in the process of roll replacement, in the process of aligning and executing a straightening roll carrying party exchange program by centering a roll shaft in a roll box unit on a roll replacement integrated frame and a cantilever type roll shaft on a bearing seat of an operating side frame, the phenomena of serious axial lead dimension deviation, parallelism, coaxiality and other shape and position deviation exist, and the actual adjustment is difficult, so that the blocking phenomenon in the process of executing the straightening roll carrying party exchange program is caused, and the integral group roll replacement process is influenced to be smoothly carried out.

Description of the embodiments
The roll changing integrated frame and the lower equipment system of the automatic roll changing vehicle have two connection modes: an integrated automatic roll changing vehicle with fixed position at the bottom of a roll changing integrated frame; the mating surfaces are coupled using fasteners. The application mode of the connection mode is that the backup roll operation on the roll changing integrated frame is carried out on the automatic roll changing vehicle at the parking position. The other is that the automatic carrier vehicle and the roll changing integrated frame are divided into two independent units; the automatic carrying vehicle is arranged at two ends or one end of the straightener on the transverse moving track. When the roll changing operation is performed, the automatic carrier vehicle and the roll changing integrated frame adopt a rapid combination mode, and the roll changing integrated frame is rapidly positioned and automatically clamped on the automatic carrier vehicle, so that the automatic roll changing vehicle which automatically runs, rapidly positions and automatically executes a straightening roll carrying party exchange program is constructed. The roll changing integrated frame can also be independently applied to roll preparation operation and maintenance operation; the roller replacement integrated roller supporting and maintenance operation can be performed in the places except the parking places of the automatic roller replacing vehicle in the adjacent area of the combined type rack straightener.
One embodiment of the roll changing integrated frame consists of a frame body (410), a roll shaft assembly unit (430), a pull claw safety locking mechanism (434), a pull claw pose detection mechanism (450), a sleeving detection device (460), a hydraulic valve group and pipeline system (470), an electric control device (490) and the like.
The frame body is used for carrying a roll shaft unit (430), a pull claw safety locking mechanism (434), a pull claw pose detection mechanism (450), a sleeving detection device (460), a hydraulic valve group and pipeline (470), an electric control device (480) and the like. The frame body fixedly connected with the carrier vehicle body is shown in fig. 4; and the frame body in a quick connection mode with the carrier vehicle body is shown in figure 5.
The frame body is an integral welding structure which is mainly formed by welding a vertical plate (411), a coaming (412), a shaft sleeve (413), a combined structure formed by a panel (415), a sleeve (414) and a rear panel (416), a combined structure formed by a foot structure (418) and a bottom plate (417) at the lower part and a plurality of rib plates, and is used as a main body of the bearing structure.
The periphery of the vertical plate (411) is covered by the coaming (412) according to the outline so as to improve the local rigidity of the frame body (410). Two rectangular holes are reserved on one side of the enclosing plate (412) of the frame body (410) up and down for installing the distribution block.
The vertical plate (411) is provided with 10 shaft sleeves (413) in two rows up and down, and is welded perpendicular to the vertical plate (411) for axially assembling 10 roll shaft units. The enclosing plate (412) forms an enclosing structure on the upper part and the end part of the vertical plate (411). The vertical plate (411) is coupled with a combined structure composed of a foot structure (418) and a bottom plate (417) and is perpendicular to the bottom plate (417).
The sleeve (413) is used for assembling the roll shaft unit (430). The position and the size of the shaft sleeve (413) arranged on the frame body vertical plate (411) correspond to the center line of the position where the straightening roller is arranged by the roller changing of the combined type frame straightener. The outline of the shaft sleeve (413) is of a stepped cylindrical structure; the front end is provided with a convex disc structure, and the inner end surface is used for welding and positioning with the vertical plate (411); the outer end surface is finished and then serves as a matching surface of the roll shaft unit (430); the inner cavity is a shaft sleeve (413) with a single cylindrical structure, and the shaft sleeve is used for axially positioning a roll shaft unit (430) after finish machining. The front end surfaces of all the shaft sleeves (413) welded on the vertical plate (411) are arranged on a vertical plane; the central line of the shaft sleeve (413) is parallel to the lower surface E of the bottom plate of the frame body. Because the consistency of the center line position, the size and the end face of all round holes for assembling the shaft sleeve (413) of the roll shaft unit (430) on the frame body is ensured by a processing machine tool, the axial assembly of the roll shaft unit (430) does not need to be adjusted, thereby avoiding assembly adjustment errors under the structural condition in the essential sense and improving the application performance.
The panel (414) is welded on the surface of the frame body vertical plate (411) and right above the shaft sleeve (413). A sleeve (414) is welded at a position corresponding to the panel (414) behind the frame body vertical plate (411), and the rear end of the sleeve (415) is sealed by a rear panel (416).
A part of the frame body vertical plate (411), the panel (414), the sleeve (415) and the rear panel (416) form a unit combination structure for installing the straightening roller pull claw safety locking mechanism (434). The horizontal axis of the unit combination structure is parallel to the axis of the shaft sleeve (413).
A part of the frame body vertical plate (411), the panel (415), the sleeve (414) and the rear panel (416) form a unit combination structure for installing the straightening roller pull claw safety locking mechanism (434). The partial unit composite structure back panel (416) may also be eliminated. When the straightening roller safety locking mechanism driven by the cam shaft is installed, the outline of the sleeve (414) can be square, and a rectangular hole is formed in the top surface of the sleeve for installing the pull claw pose detection switch assembly.
The two sides of the lower part of the frame body are provided with a combined structure of a footing structure (418) and a bottom plate (417) at the lower part, and the combined structure bears the function of a load fulcrum. The foot structure (418) is connected with the appearance of the combined structure of the bottom plate, and has enough area relative to the table surface of the carrier vehicle, so that the integrated frame and the combined gravity center after carrying are ensured to be in the outline polygonal range of the combined structure, and the safety capability of resisting dangerous overturning is obtained greatly. The safety capability of the integrated frame against dangerous toppling is extremely important when the integrated frame is separated from a carrier vehicle for application; the integrated frame can be ensured to be positioned on a horizontal plane, and cannot tip over when other fixing measures are not used, so that the intrinsic safety of the integrated frame is improved.
Four bottom plates (417) are arranged at four corners of the bottom of the frame body, a bottom plate (346) is arranged in the middle of the frame body, the marks of the bottom surface E are all on the same plane, the bottom surface E is taken as a joint surface for connecting the roll changing integrated frame and the carrier loader from the view of roll changing process function, and from the view of machining function, 5 connecting lines for installing the central line of a shaft sleeve (413) of a lower straightening roll shaft are taken as the reference of the bottom surface E on the frame body (410). The large plane formed by four corners is used as a reference, so that the parallelism between the central line of the shaft sleeve (413) and the reference plane and the parallelism between the sleeve (414) are guaranteed; meanwhile, the front end faces of all the shaft sleeves (413) are guaranteed to be on the same vertical elevation.
The structures of the frame bottom plate (417) and the bottom plate (346) are slightly different according to the different modes of fixed connection or quick connection with the carrier vehicle body.
The structure of the frame body bottom plate (417) and the bottom plate (346) which are fixedly connected with the carrier vehicle body is simpler; the lower bottom surface of the bottom plate is on the same horizontal plane; bolt holes for connecting with the carrier vehicle are distributed on the bottom plate.
The integrated frame in a quick connection mode with the carrier vehicle body is characterized in that a plurality of functional structures for fixing the frame body in the carrier vehicle positioning, quick locking and fixing, maintenance preparation occasions and the like are arranged on the frame body bottom plate (417) due to the consideration of the quick connection function in terms of use, the matching of one carrier vehicle with a plurality of integrated frames and the like.
Under the condition of the quick connection mode of the integrated frame and the carrier vehicle, the lower bottom surface of the bottom plate (417) is on the same horizontal plane; the bottom plate is distributed with: a swing bolt hole slot 4171, two cylindrical pin slots 4172 positioned laterally, and a longitudinal positioning slot 4173 after the base plate (347) is secured.
The U-shaped opening mark D on the outer edge of the bottom plate (417) is a movable joint bolt hole groove 4171 which is a movable joint bolt fastening part and is matched with a movable joint bolt on the carrier vehicle to play a role of connecting and fastening the integrated frame.
The two cylindrical pin grooves are arranged on the same axis and used for transversely positioning the integrated frame and the carrier vehicle. The cylindrical pin groove is semicircular, and the axis is arranged on the bottom plate (417) and parallel to the axis of the shaft sleeve (413).
A cylindrical pin slot on the fixed rear floor (347) is used for longitudinal positioning of the integrated rack and carrier. Under the condition of a quick connection mode of the integrated frames and the carrier vehicles, the longitudinal positioning support of the integrated frames adopts a fixing mode after assembly due to the interchangeability requirement of matching a plurality of integrated frames of one carrier vehicle; therefore, for accommodating the upper base plate (347) of the longitudinally fixed positioning support, the middle section of the bottom of the frame body is concave. The bottom plate (346) is connected with an upper bottom plate (347) in the longitudinal positioning support seat of the integrated frame, and is welded after adjustment.

The pull claw safety locking mechanism is matched with the pull claw pose detection mechanism and the sleeved detection device, and has the advantages of high automation program, short roller changing process time and the like.
In the utility model, the pull claw in the safety locking has two working position states; when the pull claw is in a vertical position, the straightening roller is allowed to be installed into the roller shaft; after the straightening roller is arranged in the roller shaft, the pull claw is turned into a horizontal position, and the hook head is embedded into the groove of the straightening roller to prevent the straightening roller from accidentally sliding on the roller shaft, so that the safety locking function is realized. Because of the limitation of the width dimension of the groove of the straightening roller, failure influence factors such as that the straightening roller is not sleeved in, or that the self factor of the pulling claw is not transferred into a horizontal pose exist; therefore, the gripper pose detection mechanism is arranged and sleeved in the detection mechanism so as to verify and ensure the effectiveness of the safety measures.

Under the condition of a transverse moving track, adopting an automatic roll changing vehicle straightening roll group integral replacement mode is a process for accurately controlling the displacement change of each part of the machine under a three-dimensional coordinate system; the disassembly, assembly and replacement process of the straightening roller is completely mechanical and automatic. In the roll changing process, in a roll changing integrated frame carried on the upper part of the automatic carrier vehicle, strict requirements on position dimensional accuracy and coaxiality form and position tolerance exist between the axial lead of a roll shaft of a hanging straightening roll and the axial lead of the roll shaft of the hanging straightening roll of a bearing seat of a stand on an operation side; the requirement of positioning precision of the automatic carrier vehicle on the transverse moving track cannot be met only by means of the electric braking performance of the driving motor.
The accurate positioning of the automatic carrier vehicle (300) on the transverse moving track is realized by the combined action of a braking and secondary positioning mechanism of a driving motor. The efficacy of the secondary positioning mechanism is realized by the interaction of a piston pin in a hydraulic pin cylinder on a transverse moving track and positioning blocks on the front end and the rear end of a vehicle body of the automatic carrier vehicle (300). Under the condition that positioning blocks are arranged at the front end and the rear end of a vehicle body of the automatic carrier vehicle (300), a driving motor of the automatic carrier vehicle (300) adopts an energy consumption braking mode.

When the roll changing operation is performed, under the measurement and control of the laser position detection device, the automatic carrier vehicle runs on the transverse moving track to a roll changing position of a roll changing space of the combined straightener frame; when the roller changing position on the transverse moving track reaches the preset position, the automatic carrier vehicle runs at a reduced speed; when the preset roll changing position is reached, under the action of electric control, the motor of the motor reducer (306) stops running and brakes, and then the braking is released, and a piston pin in a secondary positioning hydraulic pin cylinder (624) arranged on the transverse moving track (620) is lifted and inserted into the car body positioning frame (304) and the car body positioning frame (314). When the automatic carrier vehicle parks under the action of electric control, due to the deviation of parking precision, during the extending process of the hydraulic bolt (624) bolt function, the conical head part is in contact with the wall surfaces of the conical frustum-shaped holes at the lower parts of the vehicle body positioning frame (304) and the vehicle body positioning frame (314), and under the action of the inclined surface component force, the automatic carrier vehicle performs self-adaptive horizontal coordinated movement and parallel posture adjustment in the advancing direction of the transverse moving track (620). Because the position relations of the car body positioning frame (304), the car body positioning frame (314) and the hydraulic bolt cylinder (624) on the car body (302) are set according to the state that the cantilever type roll shaft of the roll changing integrated frame on the automatic carrier and the cantilever type roll shaft on the frame at the operation side are simultaneously inserted into the straightening roll during debugging, the interaction process of the car body positioning frame and the secondary positioning hydraulic bolt cylinder enables the automatic carrier to realize secondary accurate positioning at the roll changing position on the transverse moving track.
Because the combined type frame straightening machine automatic roll changing machine unitized integral roll changing process is an automatic process of automatic disassembly and assembly of straightening rolls under a three-dimensional coordinate system, under the mode of combining an automatic carrying vehicle and a roll changing integrated frame, the dimensional position precision and the coaxiality position precision between the roll shaft axis of the hanging straightening rolls on the roll changing integrated frame and the roll shaft axis on the frame of the operation side of the straightening machine are required to be realized by the integrated application of the main action elements of the positioning system structure matched with the dimensional position precision of the automatic carrying vehicle, the roll changing position precision on a track and the positioning system structure arranged on the table top of the automatic carrying vehicle.

The longitudinal locating pins (351) in the integrated frame longitudinal locating support (349) are adjusted to be positioned so that the axial lines of the longitudinal locating pins are in the X, Z axial plane, namely in the symmetrical central planes of the front left support (341) and the front right support (342).
In a matching mode that an automatic carrier vehicle is matched with a plurality of roll changing integrated frames for roll changing, as the cylindrical pins are fixed on the lower support (351) by screws, the axial lead of the longitudinal positioning pins (352) is adjusted to be in the X, Z axial plane; the lower support (351) is connected with the base (350) through bolts, the base (350) is connected with the car body (302) of the automatic carrier car through bolts, and after the adjustment of all roll changing integrated frames is finished, the lower support (351) is welded with the base (350).

3) Positioning adjustment of automatic carrier vehicle matched with multiple roll changing integrated frames
An upper support (353) of the integration frame longitudinal positioning support (348) and corresponding fasteners are coupled to the roll change integration frame. Because a matching mode that one automatic carrier vehicle is matched with a plurality of roll changing integrated frames for roll changing is adopted, the direction of an upper support (352) is regulated by taking a structural function piece in a three-point positioning system on the automatic carrier vehicle as a reference.
The upper support (352) is connected with the frame body (410) of the roll changing integrated frame by screws, and is welded and fixed with the frame body (410) of the roll changing integrated frame (400) after final adjustment and positioning.
When the automatic roll changing vehicle is positioned at a roll changing position in a roll changing area of the combined type frame, a straightening roll changing program is simulated, then a longitudinal positioning base (350) is welded with the vehicle body, and an upper support (352) is welded with a roll changing integrated frame.
In the supporting, positioning and locking system (340), four locking hydraulic cylinders (348) and four movable joint bolt assemblies (347) are used for locking and fixing the roll changing integrated frame (400) in a front left support (341), a front right support (342), a rear left support (343) and a rear right support (344) which are symmetrically arranged on four corner bases at the upper part of a vehicle body of the automatic carrier.
The head of the piston rod of the locking hydraulic cylinder (347) is tongue-shaped and is also used as a wedge-shaped pressing block matched with the pressing part of the roll changing integrated frame (400). The piston rod of a locking hydraulic cylinder (348) arranged on the vehicle body is always set in a retracted state.

The hydraulic cylinders of the safety locking claw mechanism (434) are controlled independently in consideration of intrinsic safety requirements of the roll changing integrated frame (400) and the carrying function of the integrated frame by a roller way, so that corresponding hydraulic circuits and pipe distribution modes are determined. Because the hydraulic cylinder adopts a single control mode, the problem that the pipelines for the oil supply loop of the hydraulic cylinder are densely distributed in a limited space is generated; according to the utility model, the control valve group and the pipeline system (470) adopt an oil way block and pipeline construction mode to be used as a coping strategy and scheme for coping with dense pipeline arrangement.
The control valve group and the pipeline system (470) are distributed on the upper and lower sides of the frame coaming (412) and used for controlling the safety locking pull claw mechanisms (434) corresponding to the upper and lower straightening rollers.

Two hard tube groups (484) are arranged on the upper and lower sides of the frame body and are used for locking mechanical driving hydraulic cylinders by pulling claws of the upper and lower straightening rollers; each set of 5 rows of 10 hard tubes. The rigid tube group (484) passes through the reserved holes on the rib plate at the rear of the frame body, is horizontally arranged and is fixed by a tube clamp (shown in figures 12 and 14). The upper hard tube and the lower hard tube are used for oil supply branch circuits of one hydraulic cylinder, and the five circuits are distributed in the frame body in a front-back arrangement mode.

The straightening roller is sleeved into the detection device (460) and used for detecting the horizontal depth of the straightening roller inserted into the cantilever type roller shaft, and erroneous judgment of locking of the idle roller is prevented. The sensing element signals in the pulling claw pose detection mechanism (450) are vertical position detection switches (451) and horizontal position detection switches (452) which are inductive proximity switches; because the pulling claw only has the vertical and horizontal pose states of the pulling claw, in operation, two detection switches are arranged, and one detection switch detects the induction signal, and the other detection switch does not detect the induction signal. The signal cables of the vertical position detection switch (451) and the horizontal position detection switch (452) enter the terminal box (491) through the reserved pore canal on the vertical plate (411).
The outlet cable from the test unit hose (492) in the test unit terminal box (491) is routed to the transition terminal box (493) and then into the header (494) for final access into the control box (495).

Because of the fast combination mode of the roll changing integrated frame and the carrier vehicle and the independent use requirement of the standby roll process stage, the power supply of a control box (495) in the integrated frame and the cable connection communicated with the carrier vehicle adopt a plug-in connector mode.
The integral structure frame has the advantages of simple structure, strong deformation resistance and convenient processing and use. The sleeve for assembling the roll shaft is directly welded on the frame body; the sleeve hole and the matching end surface for assembling the roll shaft are directly processed and formed on the frame body; the machine tool ensures the mutual meta-apparent size and form and position tolerance of the sleeve holes without depending on installation and adjustment, thereby ensuring the high-precision position requirement in the roll changing process.
