Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and more specifically, to a transfer device for installing a steel structure tower and a using method thereof. Background Art

[0002] In modern construction, steel structure towers are widely used due to their high strength and short construction period. During the installation of steel structure towers, transfer devices play a crucial role.

[0003] Regarding the transfer devices for installing steel structure towers, there are many existing technologies, for example: Chinese Patent Publication No. CN119142748A discloses a technology field of iron accessory transfer, in particular to an iron accessory transfer device. This patent provides an iron accessory transfer device that can move to different positions to transfer iron accessories and can also transport iron accessories to different height positions for storage. An iron accessory transfer device includes a crawler vehicle, a first motor, a rotating rod, etc. A first motor is connected to the upper part of the crawler vehicle, and a rotating rod is connected to the output shaft of the first motor. In this invention, the iron accessories to be transferred are placed in a placement vehicle, then the crawler vehicle is moved to the iron accessory storage shelf or transfer vehicle, and then the staff places the iron accessories in the placement vehicle on the first conveyor belt. The second motor is started to drive the first rotating shaft to rotate, so that the first conveyor belt rotates to transport the iron accessories, achieving the effect of being able to move to different positions to transfer the iron accessories.

[0004] However, in the actual use process, there are still some problems to be solved urgently: 1. Current transfer devices often require operators to manually carry steel parts onto the transfer device. This process is not only cumbersome but also greatly increases the labor intensity of the operators. Repeated operations for a long time are likely to cause operator fatigue, thereby affecting work efficiency and construction safety. 2. When cutting steel plates during high-altitude operations, due to the large frictional force between the steel plate and the surface of the support, operators need to exert a great deal of effort to complete the handling and cutting operations. Coupled with the limited space for high-altitude operations and few stress points, during the process of handling the steel plate, if the operator is slightly careless, there is a risk of slipping, which undoubtedly poses a serious threat to the life safety of construction workers.

[0005] Therefore, a transfer device for installing a steel structure tower and a using method thereof are proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a transfer device for installing a steel structure tower and a using method thereof to solve the problems raised in the above background art.

[0007] To solve the above technical problems, one of the objectives of the present invention is to provide a transfer device for the installation of steel structure towers, including a mobile vehicle.

[0009] As a further improvement of this technical solution, a through groove is opened inside the support base. A moving frame is provided in the through groove. Support rollers are provided on the inner wall of the moving frame.

[0010] As a further improvement of this technical solution, a support plate is provided at the bottom of the support base. A column cylinder is provided on the surface of the support plate. A sliding column is slidably provided inside the column cylinder. The sliding column is fixed to the bottom of the moving frame. A moving frame is provided between the column cylinder and the sliding column. In the natural state, the support roller is flush with the top of the support base.

[0011] As a further improvement of this technical solution, the pressing component includes an electric telescopic rod on the top of the moving frame. A fixed frame is provided at the end of the electric telescopic rod. A servo motor is provided on the side wall of the fixed frame. The output end of the servo motor penetrates through the fixed frame and a friction roller is provided at the end.

[0012] As a further improvement of this technical solution, multiple groups of friction rollers are provided inside the fixed frame. Belt shafts are provided at the ends of the friction rollers. A transmission belt is provided on the surface of the belt shafts. The friction rollers are driven by the transmission belt between them.

[0013] As a further improvement of this technical solution, an eccentric wheel is provided at the end of the friction roller. The eccentric wheel is fixed to the end of the friction roller. A connecting rope is provided at the end of the eccentric wheel. A striking ball is provided at the end of the connecting rope. When the eccentric wheel rotates, it drives the striking ball to strike the surface of the steel plate.

[0014] As a further improvement of the technical solution, the lifting assembly includes a second cylinder provided on one side of the clamping plate. A limiting plate is provided at the end of the piston rod of the second cylinder. Rack teeth are provided on both sides of the limiting plate. When the limiting plate moves, it drives the rack teeth to move in the vertical direction.

[0015] As a further improvement of the technical solution, a rotating lead screw is provided inside the through groove. A rotating gear is provided at the end of the rotating lead screw. When the rack teeth move, they drive the rotating gear to mesh and rotate. A ramp plate is provided on the surface of the rotating lead screw. When the rotating lead screw rotates, it drives the ramp plate to move in the horizontal direction.

[0016] The second object of the present invention is to provide a processing method for a transfer device for installing a steel structure tower, including the transfer device for installing a steel structure tower described in any one of the above, and including the following steps: S1. When the mobile vehicle moves to the storage bin, control the output shaft of the first motor to drive the first lead screw to rotate. When the first lead screw rotates, it drives the moving plate to move in the vertical direction. When the moving plate moves below the steel plate, control the piston rod at the end of the first cylinder to drive the moving frame to move downward in the vertical direction. During the downward movement of the moving frame until the support base fits with the ground, control the output end of the second motor to drive the main gear to rotate. When the main gear rotates, it drives the driven gear to mesh and rotate. The driven gear drives the second lead screw to rotate coaxially. When the second lead screw rotates, it drives the clamping plates to move relative to each other in the horizontal direction. During the movement of the support base, it shovels up the material plate on the ground, so that the material plate slides along the inclined plane to the surface of the support base for placement; S2. When the steel plate is placed on the surface of the support base, control the output end of the electric telescopic rod to drive the fixed frame to move in the vertical direction. During the movement of the fixed frame, it drives the friction roller to move downward. The top of the steel plate placed on the surface of the support base is limited by the friction roller. When the steel plate moves to the installation position, control the output shaft of the servo motor to drive the friction roller to rotate. Since the bottom of the friction roller is in contact with the top of the steel plate, therefore, the friction roller rotates through the transmission belt to apply a frictional force to the top of the steel plate, so that the steel plate moves on the surface of the support roller; S3. Control the piston rod at the end of the second cylinder to move downward in the vertical direction. During the movement of the second cylinder, it drives the limiting plate to move in the vertical direction. When the limiting plate moves, it drives the rack teeth to move. When the limiting plate moves above the steel plate, stop moving to limit it. At the same time, when the rack teeth move downward, they drive the rotating gear to mesh and rotate. When the rotating gear rotates, it drives the rotating lead screw to rotate coaxially. When the rotating lead screw rotates actively, it drives the ramp plate to move in the horizontal direction towards the bottom of the moving frame, so that the moving frame drives the support roller to drive the steel plate to move away from the surface of the support base in the vertical direction.

[0017] Compared with the prior art, the beneficial effects of the present invention: 1. For the transfer device used in the installation of the steel structure tower, control the output shaft of the first motor to drive the first lead screw to rotate. When the first lead screw rotates, it drives the moving plate to move vertically. When the moving plate moves below the steel plate, control the piston rod at the end of the first cylinder to drive the moving frame to move downward vertically. During the downward movement of the moving frame until the support base fits the ground, control the output end of the second motor to drive the main gear to rotate. When the main gear rotates, it drives the driven gear to mesh and rotate. The driven gear drives the second lead screw to rotate coaxially. When the second lead screw rotates, it drives the clamping plate to move relatively in the horizontal direction. During the movement of the support base, it shovels up the material plate on the ground, causing the material plate to slide along the slope surface to the surface of the support base for placement, thus avoiding the need for operators to carry the steel plate and reducing the labor intensity of the operators. 2. For the transfer device used in the installation of the steel structure tower, when cutting the steel plate, the friction roller rotates on the top of the steel plate. When the friction roller rotates, it drives the eccentric wheel to rotate coaxially. There is at least one set of eccentric wheels. When the eccentric wheel rotates, it drives the hitting ball to rotate. When the hitting ball rotates to the bottom, it knocks on the surface of the material plate, so that the sand and gravel particles adhered to the surface of the material plate fall off, avoiding the material plate from slipping due to the reduction of the friction force between the arm and the surface of the steel plate when taking the material plate, thus ensuring the installation quality of the tower body.

[0018] 3. For the transfer device used in the installation of the steel structure tower, when the rack moves downward, it drives the rotating gear to mesh and rotate. When the rotating gear rotates, it drives the rotating lead screw to rotate coaxially. When the rotating lead screw rotates actively, it drives the slope plate to move closer to the bottom of the moving frame in the horizontal direction, causing the moving frame to drive the support roller to drive the steel plate to move away from the surface of the support base vertically. At this time, control the electric telescopic rod to drive the fixed frame to move upward, so that the friction roller arranged inside the fixed frame always fits the top of the steel plate, thus realizing the automatic lifting of the moving frame and improving the convenience of using the transfer device.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] One of the purposes of the present invention is to refer to Figures 1-8 As shown, a transfer device for installing a steel structure tower is provided, including a mobile vehicle 100. Extension plates 101 are provided on both sides of the mobile vehicle 100. First motors 200 are provided on the tops of the extension plates 101. The output shafts of the first motors 200 penetrate through the extension plates 101 and a first lead screw 201 is provided at the end. A moving plate 202 is provided on the surface of the first lead screw 201. A shipping component 300 is provided below the moving plate 202. The shipping component 300 is used to clamp a steel plate. A pressing component 400 is provided inside the shipping component 300. The pressing component 400 is used to press the steel plate to keep it stable during the transfer of the steel plate. A lifting component 500 is provided above the shipping component 300. The lifting component 500 is used to limit both sides of the steel plate during blanking, and at the same time cooperate with the pressing component 400 to make the steel plate slide down for blanking.

[0025] During the transfer process of steel plates, it is usually necessary for operators to carry the steel plates onto the transfer vehicle, which increases the labor intensity of the operators. Therefore, the consignment component 300 includes a first cylinder 301 provided at the top of the moving plate 202. A moving frame 302 is provided at the end of the piston rod of the first cylinder 301. A second motor 303 is provided at the top of the moving frame 302. A main gear 304 is provided at the output end of the second motor 303. Second lead screws 305 are provided on both sides. Driven gears are provided at the ends of the second lead screws 305. When the main gear 304 rotates, it drives the driven gears to rotate. Clamping plates 306 are provided on the surfaces of the second lead screws 305. A support base 307 is provided at the bottom of the clamping plate 306. The bottom of the support base 307 is parallel to the horizontal plane. When the moving vehicle 100 moves to the storage bin, the output shaft of the first motor 200 is controlled to drive the first lead screw 201 to rotate. When the first lead screw 201 rotates, it drives the moving plate 202 to move in the vertical direction. When the moving plate 202 moves below the steel plate, the piston rod at the end of the first cylinder 301 is controlled to drive the moving frame 302 to move downward in the vertical direction. During the downward movement of the moving frame 302 until the support base 307 fits the ground, the output end of the second motor 303 is controlled to drive the main gear 304 to rotate. When the main gear 304 rotates, it drives the driven gears to mesh and rotate. The driven gears drive the second lead screws 305 to rotate coaxially. When the second lead screws 305 rotate, they drive the clamping plates 306 to move relative to each other in the horizontal direction. During the movement of the support base 307, the stock plate on the ground is shoveled up, so that the stock plate slides along the slope surface and is placed on the surface of the support base 307, thus avoiding the operators from carrying the steel plates and reducing the labor intensity of the operators.

[0026] When the steel plate moves to the installation location, due to working at high altitude, during the process of cutting the steel plate, workers need to carry and cut it. Since the frictional force between the steel plate and the surface of the support base 307 is relatively large, workers need to use a relatively large amount of force to carry it. Due to the relatively small force application points at high altitude, during the process of carrying the steel plate, it may cause the workers to slip and result in injuries to the installers. Therefore, a through groove is provided inside the support base 307, a moving frame 308 is arranged inside the through groove, support rollers 309 are arranged on the inner wall of the moving frame 308, a support plate is arranged at the bottom of the support base 307, a cylinder 310 is arranged on the surface of the support plate, a sliding column 311 is slidably arranged inside the cylinder 310, and the sliding column 311 is fixed to the bottom of the moving frame 308. A moving frame 302 is arranged between the cylinder 310 and the sliding column 311. In the natural state, the support rollers 309 are flush with the top of the support base 307. When the steel plate moves to the installation location, by pushing the moving frame 308 to move in the vertical direction, the moving frame 308 stretches the sliding column 311 during the movement. The sliding column 311 slides on the inner wall of the cylinder 310. At the same time, the sliding column 311 pulls the tension spring 312 during the movement. When the moving frame 308 drives the support rollers 309 to move away from the surface of the support base 307, pull one side of the steel plate to make the steel plate slide on the surface of the support rollers 309, which is convenient for workers to cut the steel plate, thus facilitating workers to cut the steel plate and avoiding potential safety hazards.

[0027] When the steel plate is placed on the surface of the support base 307, control the moving vehicle 100 to drive the steel plate to move. When the steel plate passes through a bumpy section during the movement, it is easy to shake, which may cause the steel plate to fall and requires secondary shoveling and clamping, affecting the handling efficiency. Therefore, the pressing component 400 includes an electric telescopic rod 401 at the top of the moving frame 302. A fixed frame 402 is arranged at the end of the electric telescopic rod 401. A servo motor 403 is arranged on the side wall of the fixed frame 402. The output end of the servo motor 403 penetrates through the fixed frame 402 and a friction roller 404 is arranged at the end. When the steel plate is placed on the surface of the support base 307, control the output end of the electric telescopic rod 401 to drive the fixed frame 402 to move in the vertical direction. The fixed frame 402 drives the friction roller 404 to move downward during the movement. The top of the steel plate placed on the surface of the support base 307 is limited by the friction roller 404, thereby preventing the steel plate from falling when the moving vehicle 100 passes through a bumpy area, and thus improving the transfer efficiency.

[0028] When the steel plate moves to the installation position, operators need to carry and cut the steel plate. Long-term high-intensity labor of operators is likely to affect the cutting speed. Therefore, multiple groups of friction rollers 404 are provided inside the fixed frame 402. Belt shafts are provided at the ends of the friction rollers 404, and a transmission belt 405 is provided on the surface of the belt shafts. The friction rollers 404 are driven by the transmission belt 405. When the steel plate moves to the installation position, the output shaft of the control servo motor 403 drives the friction rollers 404 to rotate. Since the bottom of the friction roller 404 is in contact with the top of the steel plate, the friction roller 404 applies a frictional force to the top of the steel plate through the rotation of the transmission belt 405, causing the steel plate to move on the surface of the support roller 309, reducing the labor intensity of the operator and ensuring the cutting speed of the steel plate.

[0029] Considering that when the steel plate is being transported, sand and gravel particles are likely to fall on the surface of the stacked plates when placed outdoors. When the operator picks up the steel plate, the steel plate may slip out of the hand. During the slipping process of the steel plate, it may hit the installed tower body, affecting the construction quality. Therefore, an eccentric wheel 406 is provided at the end of the friction roller 404. The eccentric wheel 406 is fixed at the end of the friction roller 404. A connecting rope is provided at the end of the eccentric wheel 406, and a hitting ball 407 is provided at the end of the connecting rope. When the eccentric wheel 406 rotates, it drives the hitting ball 407 to strike the surface of the steel plate. When cutting the steel plate, the friction roller 404 rotates on the top of the steel plate. When the friction roller 404 rotates, it drives the eccentric wheel 406 to rotate coaxially. The eccentric wheel 406 is provided with at least one group. When the eccentric wheel 406 rotates, it drives the hitting ball 407 to rotate. When the hitting ball 407 rotates to the bottom, it strikes the surface of the plate, so that the sand and gravel particles adhering to the surface of the plate fall off, avoiding the steel plate from slipping due to the reduction of the frictional force between the arm and the surface of the steel plate when picking up the plate, thus ensuring the installation quality of the tower body.

[0030] Considering that during the movement of the steel plate blanking, in order to avoid warping during the movement and causing the operating personnel to be hit by the steel plate, therefore, the lifting assembly 500 includes a second cylinder 501 provided on one side of the clamping plate 306. A limiting plate 502 is provided at the end of the piston rod of the second cylinder 501. Rack bars 503 are provided on both sides of the limiting plate 502. When the limiting plate 502 moves, it drives the rack bars 503 to move in the vertical direction. A rotating lead screw 504 is provided inside the through groove. A rotating gear 505 is provided at the end of the rotating lead screw 504. When the rack bars 503 move, they drive the rotating gear 505 to mesh and rotate. A ramp plate 506 is provided on the surface of the rotating lead screw 504. When the rotating lead screw 504 rotates, it drives the ramp plate 506 to move in the horizontal direction. When it is necessary to blank the steel plate, control the piston rod at the end of the second cylinder 501 to move downward in the vertical direction. During the movement of the second cylinder 501, it drives the limiting plate 502 to move in the vertical direction. When the limiting plate 502 moves, it drives the rack bars 503 to move. When the limiting plate 502 moves above the steel plate, it stops moving to limit it, improving the safety of the blanking operation. At the same time, when the rack bars 503 move downward, they drive the rotating gear 505 to mesh and rotate. When the rotating gear 505 rotates, it drives the rotating lead screw 504 to rotate coaxially. When the rotating lead screw 504 rotates actively, it drives the ramp plate 506 to move closer to the bottom of the moving frame 308 in the horizontal direction, so that the moving frame 308 drives the supporting roller 309 to drive the steel plate to move away from the surface of the support 307 in the vertical direction. At this time, control the electric telescopic rod 401 to drive the fixed frame 402 to move upward, so that the friction roller 404 provided inside the fixed frame 402 always fits against the top of the steel plate, thus realizing the automatic lifting of the moving frame 308 and improving the convenience of using the transfer device.

[0031] The second object of the present invention is to provide a processing method for a transfer device for installing a steel structure tower, including the transfer device for installing a steel structure tower in any one of the above, and including the following steps: S1. When the mobile vehicle 100 moves to the silo, control the output shaft of the first motor 200 to drive the first lead screw 201 to rotate. When the first lead screw 201 rotates, it drives the moving plate 202 to move in the vertical direction. When the moving plate 202 moves below the steel plate, control the piston rod at the end of the first cylinder 301 to drive the moving frame 302 to move downward in the vertical direction. During the downward movement of the moving frame 302 until the support 307 is in contact with the ground, control the output end of the second motor 303 to drive the main gear 304 to rotate. When the main gear 304 rotates, it drives the driven gear to mesh and rotate. The driven gear drives the second lead screw 305 to rotate coaxially. When the second lead screw 305 rotates, it drives the clamping plate 306 to move relative to each other in the horizontal direction. During the movement of the support 307, it shovels up the stock plate on the ground, so that the stock plate slides along the inclined plane to the surface of the support 307 for placement; S2. When the steel plate is placed on the surface of the support 307, control the output end of the electric telescopic rod 401 to drive the fixed frame 402 to move in the vertical direction. During the movement of the fixed frame 402, drive the friction roller 404 to move downward, and limit the top of the steel plate placed on the surface of the support 307 through the friction roller 404. When the steel plate moves to the installation position, control the output shaft of the servo motor 403 to drive the friction roller 404 to rotate. Since the bottom of the friction roller 404 is in contact with the top of the steel plate, therefore, the friction roller 404 rotates through the transmission belt 405 to apply a frictional force to the top of the steel plate, so that the steel plate moves on the surface of the support roller 309; S3. Control the piston rod at the end of the second cylinder 501 to move downward in the vertical direction. During the movement of the second cylinder 501, drive the limiting plate 502 to move in the vertical direction. When the limiting plate 502 moves, drive the rack 503 to move. When the limiting plate 502 moves above the steel plate, stop moving to limit it. At the same time, when the rack 503 moves downward, drive the rotating gear 505 to mesh and rotate. When the rotating gear 505 rotates, drive the rotating lead screw 504 to rotate coaxially. When the rotating lead screw 504 rotates actively, drive the ramp plate 506 to move horizontally towards the bottom of the moving frame 308, so that the moving frame 308 drives the support roller 309 to drive the steel plate away from the surface of the support 307 in the vertical direction.

10. A method for using a transfer device for installing a steel structure tower, which is implemented by the transfer device for installing a steel structure tower according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When the mobile vehicle moves to the material yard, the output shaft of the first motor is controlled to drive the first screw to rotate. When the first screw rotates, it drives the mobile plate to move in the vertical direction. When the mobile plate moves to the bottom of the steel plate, the piston rod at the end of the first cylinder is controlled to drive the mobile frame to move downward in the vertical direction. The mobile frame moves downward until the support is in contact with the ground. The output end of the second motor is controlled to drive the main gear to rotate. When the main gear rotates, it drives the driven gear to mesh and rotate. The driven gear drives the second screw to rotate coaxially. When the second screw rotates, it drives the clamping plate to move relatively in the horizontal direction. During the movement of the support, the material plate on the ground is scooped up, so that the material plate slides along the slope surface to the surface of the support for placement; S2. When the steel plate is placed on the surface of the support, the output end of the electric telescopic rod is controlled to drive the fixed frame to move in the vertical direction. During the movement of the fixed frame, the friction roller is driven to move downward, and the top of the steel plate placed on the surface of the support is limited by the friction roller. When the steel plate moves to the installation position, the output shaft of the servo motor is controlled to drive the friction roller to rotate. Since the bottom of the friction roller fits the top of the steel plate, the friction roller applies friction to the top of the steel plate through the rotation of the transmission belt, so that the steel plate moves on the surface of the support roller; S3. Control the piston rod at the end of the second cylinder to move downward in the vertical direction. During the movement of the second cylinder, the limit plate is driven to move in the vertical direction. When the limit plate moves, it drives the rack to move. When the limit plate moves above the steel plate, it stops moving to limit it. At the same time, when the rack moves downward, it drives the rotating gear to engage and rotate. When the rotating gear rotates, it drives the rotating screw to rotate coaxially. When the rotating screw actively rotates, it drives the ramp plate to move toward the bottom of the moving frame in the horizontal direction, so that the moving frame drives the support roller to drive the steel plate away from the support surface in the vertical direction.
