[0006] The upper ends of the four support columns arranged on both sides are provided with top plates, and the two top plates are symmetrically arranged on the left and right. The tops of the four support columns are fixedly connected to the bottoms of the two top plates respectively, and fixed frames are fixedly installed on the opposite sides of the tops of the two top plates, and a hexagonal sleeve is arranged between the two fixed frames, and hexagonal rods are arranged on both sides of the hexagonal sleeve. A second motor is fixedly installed on the other side of the top of the top plate arranged on the right side, a driving gear is arranged on one side of the second motor, and a driven gear is arranged on the top of the driving gear, and the surfaces of the two hexagonal rods correspond to the interiors of the two fixed frames, and winding rollers are fixedly installed, and the surfaces of the two winding rollers are wound with hanging ropes.

[0007] One end of the bidirectional screw is movably connected to a bearing fixedly installed at the top position on one side of the base.

[0010] One end of the hexagonal rod arranged on the left side passes through the interior of the left fixing frame and is movably connected to a bearing fixedly installed at the top position on one side of the inner wall of the fixing frame.

[0013] A matching device for synchronously lifting and installing a large-span roof steel structure of a gymnasium comprises the following steps:

[0014] Step 1: First, place the two steel structures that need to be installed in the two rectangular grooves under the two connecting plates respectively. Then, control the two hydraulic cylinders to drive the clamping plates to move downward and fix the two steel structures on the rectangular frame. Make sure that the clamping plates have enough clamping force on the steel structures to ensure that the steel structures will not slip or shake during subsequent operations.

[0015] Step 2, after the steel structure is clamped and stabilized, start the first motor, the first motor drives the first output shaft to rotate, and then drives the bidirectional screw to rotate. Since both sides of the surface of the bidirectional screw are threadedly connected with threaded plates, when the bidirectional screw rotates, the two threaded plates will move synchronously relative to each other, and the two threaded plates simultaneously drive the two support plates at the bottom to slide on the two guide rods respectively. At the same time, the support wheels at the bottom of the support plates roll at the bottom of the base, so that the threaded plates can play a stable supporting effect during the movement. The two threaded plates simultaneously drive the two support columns at the top to move relative to each other along the two moving grooves, and then move the two fixed steel structures relative to each other. When the connection on the opposite side of the two steel structures moves to a suitable connection position, the construction personnel install the two steel structures together. At the same time, since the hexagonal sleeve is socketed with the two hexagonal rods, the two hexagonal rods can move in the hexagonal sleeve.

[0016] Step three, after the two steel structures are installed in abutment, if they need to be lifted to a specified height, control the second motor to make the driving gear drive the driven gear to rotate, the driven gear drives the right hexagonal rod to rotate, the right hexagonal rod drives the hexagonal sleeve and the left hexagonal rod to rotate synchronously, and during the synchronous rotation of the two hexagonal rods, the winding rollers in the two fixed frames are also driven to rotate, and during the synchronous rotation of the two winding rollers, the two lifting ropes are pulled upward to be reeled in, and the lifting ropes pull the lifting plate upward through the hanging rings, and the lifting plates on both sides slide along the surfaces of the support columns on both sides respectively, and the steel balls in the circular grooves on the lifting plates roll against the surfaces of the support columns, ensuring that the lifting plates will not shake during vertical lifting and lowering, thereby improving the overall stability, and performing subsequent installation operations after the two steel structures installed in abutment are lifted to a specified height.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The matching device for synchronous lifting and installation of the large-span roof steel structure of the large gymnasium is designed with a bidirectional screw, a first motor, a threaded plate, a support column, a lifting plate, a hexagonal rod, a winding roller, a hexagonal sleeve, a suspension rope, a second motor, a driving gear and a driven gear. The first motor is controlled to rotate the bidirectional screw. The threaded transmission of the bidirectional screw and the two threaded plates can realize the synchronous relative movement of the two fixed steel structures until they reach the precise matching position, which significantly improves the matching installation efficiency. When the matching installation of the steel structure is completed, the second motor is controlled to drive the hexagonal rod and the hexagonal sleeve to rotate synchronously by utilizing the transmission of the driving gear and the driven gear. The rotation of the hexagonal rod further drives the winding roller in the fixed frame to rotate, and the two suspension ropes are synchronously wound up to realize the rapid and synchronous lifting of the steel structure. The operation is convenient and fast, which improves the construction efficiency. The design of the guide rod, support plate, support wheel, circular groove and steel ball, the guide rod provides a precise sliding path for the support plate, ensuring the linearity and stability during the movement, and the support wheel at the bottom of the support plate rolls on the guide rod, which effectively reduces the friction and makes the movement smoother. At the same time, the design of the support wheel also increases the load-bearing capacity and stability of the device. During the vertical lifting process of the lifting plate, the steel ball in the circular groove rolls with the surface of the support column to ensure the smoothness and accuracy of the lifting. The design of the steel ball reduces the friction between the lifting plate and the support column, making the lifting process smoother, which plays an important role in the stability of the steel structure during the counterpart installation or lifting operation, and provides reliable technical support for the installation of large-span roof steel structures of large gymnasiums.

[0036] A matching device for synchronously lifting and installing a large-span roof steel structure of a gymnasium comprises the following steps:

[0037] Step 1. First, place the two steel structures that need to be installed in the two rectangular grooves 18 under the two connecting plates 15 respectively. Then, control the two hydraulic cylinders 16 to drive the clamping plates 19 to move downward and fix the two steel structures on the rectangular frame 17. Make sure that the clamping plates 19 have sufficient clamping force on the steel structures to ensure that the steel structures will not slip or shake during subsequent operations.

[0038] Step 2, after the steel structure is clamped and stabilized, start the first motor 3, the first motor 3 drives the first output shaft to rotate, and then drives the bidirectional screw 2 to rotate. Since both sides of the surface of the bidirectional screw 2 are threadedly connected with threaded plates 6, when the bidirectional screw 2 rotates, the two threaded plates 6 will move synchronously relative to each other, and the two threaded plates 6 simultaneously drive the two support plates 5 at the bottom to slide on the two guide rods 4 respectively. At the same time, the support wheels 7 at the bottom of the support plates 5 roll at the bottom of the base 1, so that the threaded plates 6 play a stable supporting effect during the movement. The two threaded plates 6 simultaneously drive the two support columns 10 at the top to move relative to each other along the two moving grooves 9, and then move the two fixed steel structures relative to each other. After the connection on the opposite side of the two steel structures moves to a suitable connection position, the construction personnel install the two steel structures in a mating manner. At the same time, since the hexagonal sleeve 25 is sleeved with the two hexagonal rods 23, the two hexagonal rods 23 can move in the hexagonal sleeve 25.

[0039] Step 3, after the two steel structures are installed in abutment, if it is necessary to lift them to a specified height, control the second motor 27 to make the driving gear 28 drive the driven gear 29 to rotate, and the driven gear 29 drives the right hexagonal rod 23 to rotate, and the right hexagonal rod 23 drives the hexagonal sleeve 25 to rotate synchronously with the left hexagonal rod 23. During the synchronous rotation of the two hexagonal rods 23, the winding rollers 24 in the two fixed frames 22 are driven to rotate at the same time. During the synchronous rotation of the two winding rollers 24, the two lifting ropes 26 are pulled upward to be wound up, and the lifting ropes 26 pull the lifting plate 11 upward through the hanging ring 20, and the lifting plates 11 on both sides slide along the surfaces of the support columns 10 on both sides respectively, and the steel balls 13 in the circular grooves 12 on the lifting plates 11 roll against the surfaces of the support columns 10, ensuring that the lifting plates 11 will not shake during vertical lifting and lowering, thereby improving the overall stability, and performing subsequent installation operations after the two steel structures installed in abutment are lifted to a specified height.

[0040] In summary: the matching device for synchronous lifting and installation of the large-span roof steel structure of the large gymnasium, through the design of the bidirectional screw 2, the first motor 3, the threaded plate 6, the support column 10, the lifting plate 11, the hexagonal rod 23, the winding roller 24, the hexagonal sleeve 25, the suspension rope 26, the second motor 27, the driving gear 28 and the driven gear 29, controls the first motor 3 to rotate the bidirectional screw 2, and through the threaded transmission of the bidirectional screw 2 and the two threaded plates 6, the two steel structures after the pairing and fixing can be synchronously moved relative to each other until they reach the precise matching position, which significantly improves the matching installation efficiency. When the matching installation of the steel structure is completed, by controlling the second motor 27, the transmission of the driving gear 28 and the driven gear 29 is utilized to drive the hexagonal rod 23 and the hexagonal sleeve 25 to rotate synchronously, and the rotation of the hexagonal rod 23 further drives the winding roller 24 in the fixed frame 22 to rotate, and synchronously winds up the two suspension ropes 26, so as to realize the rapid installation of the steel structure. Synchronous lifting, matching and lifting operations are convenient and fast, which improves the construction efficiency. The design of the guide rod 4, support plate 5, support wheel 7, circular groove 12 and steel ball 13, the guide rod 4 provides a precise sliding path for the support plate 5, ensuring the linearity and stability during the movement, and the support wheel 7 at the bottom of the support plate 5 rolls on the guide rod 4, which effectively reduces the friction and makes the movement smoother. At the same time, the design of the support wheel 7 also increases the load-bearing capacity and stability of the device. During the vertical lifting process of the lifting plate 11, the steel ball 13 in the circular groove 12 rolls in contact with the surface of the support column 10, ensuring the smoothness and accuracy of the lifting. The design of the steel ball 13 reduces the friction between the lifting plate 11 and the support column 10, making the lifting process smoother, thereby playing an important role in the stability of the steel structure during matching installation or lifting operations, and providing reliable technical support for the installation of large-span roof steel structures of large gymnasiums.

Then, two hydraulic cylinders (16) are controlled to drive the clamping plates (19) to move downward and fix the two steel structures on the rectangular frame (17). It is ensured that the clamping plates (19) have sufficient clamping force on the steel structures to ensure that the steel structures will not slip or shake during subsequent operations. Step 2: After the steel structure is clamped and stabilized, start the first motor (3), the first motor (3) drives the first output shaft to rotate, and then drives the bidirectional screw (2) to rotate. Since both sides of the surface of the bidirectional screw (2) are threadedly connected with threaded plates (6), when the bidirectional screw (2) rotates, the two threaded plates (6) will move synchronously relative to each other, and the two threaded plates (6) will simultaneously drive the two support plates (5) at the bottom to slide on the two guide rods (4), and at the same time, the support wheel (7) at the bottom of the support plate (5) moves along with the bottom of the base (1). The threaded plate (6) is rolled so that it can play a stable supporting role during the movement. The two threaded plates (6) simultaneously drive the two support columns (10) at the top to move relatively along the two moving grooves (9), thereby moving the two fixed steel structures relatively. When the connection points on the opposite sides of the two steel structures are moved to a suitable connection position, the construction personnel perform a docking installation on the two steel structures. At the same time, since the hexagonal sleeve (25) is sleeved with the two hexagonal rods (23), the two hexagonal rods (23) can move in the hexagonal sleeve (25); Step 3: After the two steel structures are installed in a butt-jointed manner, if it is necessary to lift them to a specified height, the second motor (27) is controlled to make the driving gear (28) drive the driven gear (29) to rotate, and the driven gear (29) drives the right hexagonal rod (23) to rotate, and the right hexagonal rod (23) drives the hexagonal sleeve (25) and the left hexagonal rod (23) to rotate synchronously. During the synchronous rotation of the two hexagonal rods (23), the winding rollers (24) in the two fixed frames (22) are driven to rotate at the same time, and the two winding rollers (24) rotate synchronously. During the process, the two hanging ropes (26) are pulled upward and retracted, and the hanging ropes (26) pull the lifting plate (11) upward through the hanging rings (20), and the lifting plates (11) on both sides slide along the surfaces of the support columns (10) on both sides respectively, and the steel balls (13) in the circular grooves (12) on the lifting plates (11) roll along the surfaces of the support columns (10), ensuring that the lifting plates (11) will not shake during vertical lifting, thereby improving the overall stability. When the two steel structures installed in pairs are lifted to a specified height, subsequent installation operations are carried out.
