Description

Technical Field

[0001] The present invention relates to the technical field of coil transportation, and specifically provides a wireless operation control system for a coil turnover and cross-span flat trolley. Background Art

[0002] When processing steel coils, in order to facilitate the transportation of coils (narrow coils, narrow strips), the coils are usually placed on corresponding flat trolleys, and the automatic transfer and transportation of the coils are realized through the operation of the flat trolleys.

[0003] For example, in a Chinese patent with the publication number: CN217912762U, the patent name: Continuous casting machine transverse transfer trolley, and the publication date: November 29, 2022, the top of the support frame is symmetrically provided with track grooves, an electric trolley is movably installed on the top of the support frame, moving wheels are symmetrically installed at both ends of the electric trolley, and movable grooves are symmetrically opened at one end of both sides of the electric trolley. By the combined use of a locking knob and a fixing screw, the positions of the movable block and the limiting rod can be adjusted. When the transported slab is located on the top of the electric trolley, the limiting rod can limit the position of the slab, so that the slab is at the center position of the top end of the electric trolley, which is convenient for subsequent positioning and grasping, preventing the slab from being placed obliquely, resulting in the subsequent transfer and extraction device being unable to accurately grasp the slab. And the scale line plays a reference role in the position of the limiting rod, and the position of the limiting rod can also be changed according to the different sizes of the slab, so as to ensure that slabs of different sizes can also be accurately placed in the middle of the top end of the electric trolley. Among the above-mentioned existing technologies, the following technical problems exist: When the existing trolley is used on the track, it is not convenient to monitor the surrounding obstacles. When the obstacles approach and no timely warning can be given, unnecessary safety accidents are likely to occur. At the same time, when the trolley is running, it is not convenient to make timely deceleration and braking treatments on the trolley according to the approaching distance of the obstacles in real time, thereby reducing the safety of the trolley during use.

[0004] Therefore, we propose a wireless operation control system for a coil turnover and cross-span flat trolley to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a wireless operation control system for a coil turnover and cross-span flat trolley to solve the problems in the above background art that when the existing trolleys on the market are used on the track, it is not convenient to monitor the surrounding obstacles. When the obstacles approach and no timely warning can be given, unnecessary safety accidents are likely to occur. At the same time, when the trolley is running, it is not convenient to make timely deceleration and braking treatments on the trolley according to the approaching distance of the obstacles in real time, thereby reducing the safety of the trolley during use.

[0006] To achieve the above object, the present invention provides the following technical solution: A wireless operation control system for a coil turnover cross-span flat trolley, including a trolley body and a support platform installed above the trolley body.

[0008] By adopting the above technical solution, through the infrared sensors in the advancing and retreating directions of the trolley body, it is possible to monitor the surrounding obstacles when the trolley body moves.

A power tooth plate is connected to the side of the moving plate, and the support platform is interconnected with the trolley body through auxiliary springs. A linkage gear rod is arranged on the side of the power tooth plate, and a positioning clamping rod is installed on the linkage gear rod. The linkage gear rod and the positioning clamping rod are symmetrically arranged with respect to the vertical central axis of the support platform. A first rubber sleeve is installed at the upper end of the positioning clamping rod far from the center direction of the trolley body, and a second rubber sleeve is installed at the upper end of the positioning clamping rod close to the center direction of the trolley body. The interiors of the first rubber sleeve and the second rubber sleeve are hollow structures.

[0010] By adopting the above technical solution, when a coil is placed on the support platform, the weight of the coil can cause the moving plate to drive the power tooth plate to move downward, thereby causing the engaged linkage gear rod to drive the positioning clamping rod to rotate.

[0011] Preferably, a plurality of auxiliary springs are evenly distributed below the support platform, and the moving plate at the lower end of the support platform can slide on the trolley body.

[0012] By adopting the above technical solution, through the auxiliary springs provided at the bottom of the support platform, auxiliary support for the support platform can be provided, and when the support platform is unloaded, a reset elastic force for the support platform can be provided.

[0013] Preferably, an overload control module is provided on the limiting module, and the overload control module shares a set of systems with the deceleration module and the braking module in the hierarchical response module.

[0014] By adopting the above technical solution, the overload control module, the deceleration module and the braking module share a set of systems, so that the whole is integrally arranged, and a single module can simultaneously respond to overload control and braking.

[0015] Preferably, the second rubber sleeve is connected to the receiving block through an air delivery pipe, and the inside of the receiving block is connected to a piston plate through a built-in spring. A braking frame is fixed on the piston plate, and one end of the braking frame extending out of the receiving block is located on the side of the guide wheel.

[0018] By adopting the above technical solution, by changing the magnitude of the normal pressure between the braking frame and the guide wheel, the deceleration or braking treatment of the guide wheel can be realized.

[0019] Preferably, an intervention module is arranged on the side of the braking module. When the infrared sensor monitors that an obstacle is at a dangerous distance, the intervention module controls the braking module to immediately respond, and the braking module is used to clamp and position the guide wheel.

[0020] By adopting the above technical solution, through the setting of the intervention module, the trolley can be braked in time when the surrounding staff is close to the trolley body.

[0021] Preferably, the intervention module includes an air injection pipe, the air injection pipe is connected to the receiving block, an electromagnetic on-off valve is installed on the air injection pipe, and one end of the air injection pipe far from the receiving block is connected to an air pump.

[0023] Compared with the prior art, the beneficial effect of the present invention is that: for the wireless operation control system of the coil turnover and cross-span flat trolley, the infrared sensors arranged in the forward and backward directions of the trolley body can detect surrounding obstacles, and at the same time, deceleration or braking treatment is performed according to the distance of the obstacles to ensure the safety of the surrounding operating environment; 1. A positioning clamping rod is provided. After the steel coil is placed on the support table, the weight of the steel coil can exert pressure on the support table. After the support table is pressed, the moving plate can move downward. After the moving plate moves downward, the power tooth plate can move synchronously. Through the movement of the power tooth plate, the meshing-connected linkage gear rod can drive the positioning clamping rod to rotate towards the steel coil, and the rotated positioning clamping rod is used to position the transferred steel coil, improving the stability of the steel coil during movement; 2. An infrared sensor is provided. When the trolley body moves, the infrared sensor can monitor the distance to surrounding obstacles. The grading response module makes the deceleration module and the braking module respond according to the distance of the obstacles. At the same time, when the deceleration module and the braking module are working, the alarm can emit sound and light alarms to remind the surrounding staff to operate at a safe distance; 3. A piston plate is provided. The rotation angle of the positioning clamping rod is controlled according to the weight of the steel coil. When the rotation angle of the positioning clamping rod is too large, the second rubber sleeve on it is squeezed against the coil material, and the internal air flow enters the inside of the accommodating block through the air delivery pipe. After the air flow inside the accommodating block increases, it can push the piston plate and the braking frame to move towards the direction of the guide wheel. The braking of the trolley body is realized by pressing the braking frame against the guide wheel. When overloaded, the trolley body cannot operate normally, thereby protecting the trolley body and improving the safety of the trolley body itself. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Example 1: Please refer to Figures 1-9, when the existing trolley is used on the track, it is not convenient to monitor the surrounding obstacles. When the obstacles approach and no timely warning can be given, unnecessary safety accidents are likely to occur. At the same time, when the trolley is running, it is not convenient to make timely deceleration and braking treatments for the trolley according to the approaching distance of the obstacles in real time, thereby reducing the safety of the trolley during use. To solve this technical problem, the following technical content is disclosed in this embodiment. A wireless operation control system for a coil turnover and overpass flat trolley includes a trolley body 1 and a support platform 2 installed above the trolley body 1. Guide wheels 3 are installed at the bottom of the trolley body 1, and the middle rotating shaft of the guide wheels 3 is connected to the output shaft of the motor through a bevel gear set 4. Infrared sensors 5 are installed on both the left and right sides of the trolley body 1. The infrared sensors 5 are connected to the controller. The output end of the controller is connected to the input end of the data processing module, and the data processing module is connected to the hierarchical response module. The hierarchical response module realizes deceleration and braking according to the distance from the obstacle, and the hierarchical response module is connected to the alarm 6 on the trolley body 1. The infrared sensors 5 are supported by a wireless network receiving module. The infrared sensors 5 are arranged in the forward and backward directions of the trolley body 1. A limiting module is arranged below the support platform 2. The limiting module includes a moving plate 7 fixed to the lower end of the support platform 2. A power tooth plate 8 is connected to the side of the moving plate 7, and the support platform 2 is connected to the trolley body 1 through an auxiliary spring 9. A linkage gear rod 10 is arranged on the side of the power tooth plate 8, and a positioning clamping rod 11 is installed on the linkage gear rod 10. The linkage gear rod 10 and the positioning clamping rod 11 are symmetrically arranged about the vertical central axis of the support platform 2. The upper end of the positioning clamping rod 11 far from the center of the trolley body 1 is installed with a first rubber sleeve 12, and the upper end of the positioning clamping rod 11 close to the center of the trolley body 1 is installed with a second rubber sleeve 13. The interiors of the first rubber sleeve 12 and the second rubber sleeve 13 are hollow structures. A plurality of auxiliary springs 9 are evenly distributed below the support platform 2, and the moving plate 7 at the lower end of the support platform 2 can slide on the trolley body 1. The second rubber sleeve 13 is connected to a receiving block 15 through an air delivery pipe 14, and the interior of the receiving block 15 is connected to a piston plate 16 through a built-in spring 17. A brake frame 18 is fixed to the piston plate 16, and one end of the brake frame 18 extending out of the receiving block 15 is located at the side of the guide wheel 3. The brake frame 18 is symmetrically arranged about the horizontal central axis of the guide wheel 3, and the brake frame 18 is slidably connected to the trolley body 1. The side surface of the brake frame 18 in contact with the guide wheel 3 is set as a rough surface. An intervention module is arranged on the side of the braking module. The intervention module is used to control the braking module to immediately respond when the infrared sensors 5 detect that the obstacle is at a dangerous distance, and use the braking module to clamp and position the guide wheel 3. The intervention module includes an air injection pipe 19, and the air injection pipe 19 is connected to the receiving block 15. An electromagnetic on-off valve 20 is installed on the air injection pipe 19, and the end of the air injection pipe 19 far from the receiving block 15 is connected to an air pump 21.

[0028] Place the corresponding coil material on the support table 2. After the coil material is placed on the support table 2, the weight of the coil material can exert pressure on the support table 2. After the support table 2 is pressed, the moving plate 7 can move downward. After the moving plate 7 moves, it can drive the power tooth plate 8 to move. After the power tooth plate 8 moves, the meshing-connected linkage gear rod 10 can rotate. By using the rotation of the linkage gear rod 10, the positioning clamp rod 11 can rotate synchronously, thereby clamping the steel coil. The first rubber sleeve 12 and the second rubber sleeve 13 are respectively arranged on the two sides of the positioning clamp rod 11. The elastic deformation of the first rubber sleeve 12 and the second rubber sleeve 13 plays a role in clamping and buffering. By turning on the motor, the guide wheel 3 can be rotated by using the bevel gear set 4, so as to realize the automatic movement of the trolley body 1. During the movement, the infrared sensor 5 detects the surrounding obstacles, and transmits the monitoring data to the data processing module. The data calculated by the data processing module is transmitted to the hierarchical response module. When the distance between the obstacle and the trolley body 1 is 3m - 5m, the controller controls the electromagnetic on-off valve 20 to open, and uses the air inflation pump 21 to inflate the inside of the receiving block 15. After the air inflation pump 21 inflates the inside of the receiving block 15, the thrust of the air flow can make the piston plate 16 drive the brake frame 18 to move towards the direction of the guide wheel 3. By the contact between the brake frame 18 and the guide wheel 3, the trolley body 1 can be decelerated. When the distance between the obstacle and the trolley body 1 is less than 3m, the air inflation pump 21 increases the inflation amount of the inside of the receiving block 15, so that the piston plate 16 drives the brake frame 18 to move a larger distance towards the guide wheel 3, thereby increasing the normal pressure between the brake frame 18 and the guide wheel 3, and realizing the braking treatment of the guide wheel 3, so as to avoid the operator being at risk of safety such as the narrow coil or narrow strip of the coil material falling and the trolley colliding when walking along with the vehicle at a close distance.

[0029] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. The following technical content is disclosed in this embodiment. An overload control module is arranged on the limit module. The overload control module shares a set of systems with the deceleration module and the braking module in the hierarchical response module. The second rubber sleeve 13 is connected to the receiving block 15 through an air pipe 14, and the inside of the receiving block 15 is connected to the piston plate 16 through a built-in spring 17. A brake frame 18 is fixed on the piston plate 16, and one end of the brake frame 18 extending out of the receiving block 15 is located on the side of the guide wheel 3. The brake frame 18 is symmetrically arranged about the horizontal central axis of the guide wheel 3, and the brake frame 18 is slidably connected to the trolley body 1. The side surface of the brake frame 18 in contact with the guide wheel 3 is set as a rough surface.

[0030] Since two support platforms 2 are installed on the trolley body 1, and a set of limit modules are correspondingly arranged on the sides of the two support platforms 2, and second rubber sleeves 13 are installed at the upper ends of the positioning clamping rods 11 on the sides of the two support platforms 2 close to the center direction of the trolley body 1. At the same time, the second rubber sleeves 13 are interconnected with the accommodating block 15 through air pipes 14. When a coil material is placed on one of the support platforms 2, the weight of the coil material can cause the moving plate 7 to move downward, and the positioning clamping rod 11 on its side rotates towards the direction of the support platform 2. After the positioning clamping rod 11 rotates, the second rubber sleeve 13 on it is squeezed against the coil material. After the second rubber sleeve 13 is pressed, the air flow inside it can enter the inside of the accommodating block 15 through the air pipe 14. Although the second rubber sleeve 13 on the positioning clamping rod 11 on the side of the other support platform 2 is also connected to the accommodating block 15 through the air pipe 14, the second rubber sleeve 13 is already at the expansion limit state in the initial state. Therefore, it cannot enter the second rubber sleeve 13 on the positioning clamping rod 11 on the side of the other support platform 2. The air flow only pushes the piston plate 16 inside the accommodating block 15 to move. When a coil material is placed on the other support platform 2 in the same way, after the same positioning clamping rod 11 rotates, the air flow inside its second rubber sleeve 13 will also enter the inside of the accommodating block 15 through the air pipe 14. As the air flow inside the accommodating block 15 increases, it can further push the piston plate 16 to move. When the weights of the coil materials on the two support platforms 2 are overloaded, the moving distance of the piston plate 16 inside the accommodating block 15 is large, and the brake frame 18 on the piston plate 16 will press against the side of the guide wheel 3, realizing the braking of the guide wheel 3, so that the trolley body 1 cannot operate normally in the overloaded state, realizing the overload protection of the trolley body 1, reducing the probability of the equipment running overloaded, and improving the service life of the equipment.

[0031] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
