Description

Technical Field

[0001] The invention relates to the field of scrap steel basket vehicles, and in particular to a safety anti-falling control device for a scrap steel basket vehicle and a use method thereof. Background Art

[0002] Inclined track basket cars are specialized transport equipment designed to run along fixed inclined tracks, with the slope of the track typically reaching or exceeding 15°. This type of equipment is widely used in industrial scenarios such as steel mills and foundries, primarily responsible for the important task of transporting materials such as scrap steel. Its core function is to smoothly and efficiently transport scrap steel placed on the ground along an inclined track to the feed openings of high-altitude furnaces, such as converters and electric arc furnaces. It can also be used to transport processed materials from high altitudes downward, enabling flexible transfer of materials between different heights.

[0003] Inclined track-based basket carts achieve this functionality thanks to their tilted tracks, which create a material transfer channel between high and low locations. However, the height difference and tilt angle of the tracks present certain safety risks during operation. To ensure operational safety, the equipment must be equipped with specialized drive mechanisms and safety devices. The drive mechanism provides power for the basket cart, ensuring it travels along the track at the predetermined speed and direction. Safety devices, such as fall arresters, play a key role in preventing the basket cart from falling in the event of an emergency.

[0004] After searching relevant patent documents, it was discovered that a scrap steel transfer basket vehicle with application number 202320506834.4, which is designed to prevent falling, has a certain innovative design. The basket vehicle mainly includes a base, on the top wall of which is a placement plate, and the top wall of the placement plate is provided with a limiting mechanism and a fixing mechanism. During actual operation, the invention uses a first servo motor to precisely control the forward and backward movement of the first limiting plate, thereby reliably limiting the forward and backward position of the transport basket placed on the placement plate; at the same time, the coordinated action of the second limiting plate and two springs is used to effectively limit the left and right position of the transport basket, preventing the transport basket from sliding off the placement plate in multiple directions. In addition, the device also uses a fourth servo motor to control the transmission system of pulleys and belts to realize the function of automatically driving the transport basket loaded with scrap steel to move to the placement plate, avoiding the tedious process of manually moving the transport basket, significantly reducing the workload of workers, and improving the efficiency and safety of material transfer.

[0005] However, in the existing technical solutions, although some safety protection measures have been taken into consideration, there are still some areas that need improvement. When the driving mechanism of the inclined rail-type material basket car fails, such as the chain suddenly breaks, the motor loses control, etc., the material basket car will lose power control and then slide down at an excessive speed. At this time, the anti-drop device will start working quickly, and try to prevent the material basket car from continuing to fall by inserting the pawl into the anti-drop hole pre-set on the track. However, in actual applications, since the basket car loaded with a large amount of scrap steel has a large mass and inertia, it is often difficult to achieve the ideal locking effect by relying solely on the anti-drop device for locking. When the anti-drop device is subjected to a huge impact force, the pawl may wear, deform, or the anti-drop hole may be damaged, resulting in loose locking, or even unable to effectively prevent the material basket car from sliding down, thereby posing a serious threat to the safety of equipment and personnel. Summary of the Invention

[0006] The object of the present invention is to provide a safety anti-falling control device for a scrap steel basket cart and a method of using the same, so as to solve the problems raised in the background technology described above and overcome the technical defects thereof.

[0008] As a further solution of the present invention: the basket trolley assembly also includes a shock-absorbing spring fixedly installed at the bottom of both ends of the support frame, a load-bearing frame is fixedly installed on the outside of the bottom end of the shock-absorbing spring, and a load-bearing basket is installed at the middle position of the upper end of the support frame.

[0009] As a further solution of the present invention: wheel axles are installed at both ends of the carrier frame, and track wheels are rotatably installed at both ends of the wheel axles.

[0010] As a further solution of the present invention: the anti-fall control assembly further includes a plug body slidably mounted inside the fixed hydraulic cylinder, and the middle position of the lower end of the plug body is fixedly connected to the connecting rod.

[0011] As a further solution of the present invention: a motor seat is fixedly mounted on one end of the assembly seat, a control motor is fixedly mounted on the lower end of the motor seat, and an output end of the control motor is fixedly connected to the rotating shaft.

[0012] As a further solution of the present invention: the outer wall of the fixed hydraulic cylinder is penetrated by a connecting delivery pipe located below the plug body, and the output end of the connecting delivery pipe is connected to the first anti-falling auxiliary component and the second anti-falling auxiliary component.

[0013] As a further solution of the present invention: the first anti-fall auxiliary component includes a fixed block fixedly installed at the bottom end of one end of the carrier frame, a socket is fixedly installed on the side wall of the fixed block close to the track, an oil chamber is provided inside the socket, a plug-in column is slidably installed inside the oil chamber, and a socket matching the plug-in column is provided on one side edge of the track.

[0014] As a further solution of the present invention: the second anti-fall auxiliary component includes an assembly frame fixedly mounted at the bottom end of the middle position of the carrier frame, an oil channel is opened inside the assembly frame, the upper end of the oil channel is connected to the first connecting channel, and the bottom end of the oil channel is connected to the second connecting channel.

[0015] As a further solution of the present invention: an upper clamping seat is fixedly installed on the upper end of the side wall of the assembly frame, a first control oil chamber is opened at the inner bottom end of the upper clamping seat, an upper clamping block is slidably installed inside the first control oil chamber, a lower clamping seat is fixedly installed on the lower end of the side wall of the assembly frame, a second control oil chamber is opened at the inner upper end of the lower clamping seat, a lower clamping block is slidably installed inside the second control oil chamber.

[0016] As a further solution of the present invention: a method for using a safety anti-falling control device for a scrap steel basket cart comprises the following steps: S1: Buckle-fit anti-fall: Through the inertia or gravity of the basket car, the hook can naturally droop and quickly contact the supporting sleeper, directly snapping into the buckle slot, and anti-fall can be achieved through mechanical size matching; S2. Plug-in anti-falling: The hook drives the hydraulic system to insert the plug-in column into the track socket. Through the synergistic effect of mechanical hooking and hydraulic auxiliary braking, it achieves the multiple anti-falling effects of "double protection + force optimization + buffering and energy absorption"; S3. Clamping to prevent falling: The second anti-fall auxiliary component completely restricts the freedom of the basket car when falling through a three-dimensional constraint system of longitudinal, lateral and vertical constraints, reducing the risk of derailment.

[0017] As a further solution of the present invention: Compared with the prior art, the present invention has the following beneficial effects: The hook size of the present invention is larger than the gap between the assembly seat and the supporting rail sleeper, which ensures from the physical size that as long as the basket car slides down, the hook will be able to contact and hook the engaging groove. When the hook size is larger than the gap, there is no need to rely on complex triggering mechanisms such as springs and sensors. Only through the inertia or gravity of the basket car sliding down, the hook can naturally droop and quickly contact the supporting rail sleeper and directly snap into the engaging groove. This design does not require complex "precision triggering" components such as sensors and hydraulic drive devices. Anti-falling can be achieved only through mechanical size matching. The structure is simple and reduces failure points such as aging of electronic components and leakage of hydraulic pipelines. It is suitable for the scrap steel workshop environment with a lot of dust and high vibration. During maintenance, it is only necessary to check whether the hook is deformed and whether the engaging groove is worn. There is no need to calibrate precision components, which reduces labor and time costs and ensures that the device is in an effective state for a long time.

[0018] This invention utilizes a "hook-engagement triggering hydraulic assisted braking" design. The hook drives the hydraulic system to insert the plug-in post into the track socket. The synergistic effect of mechanical hooking and hydraulic assisted braking achieves the multiple advantages of "double protection + force optimization + buffering and energy absorption." The hook preferentially engages the engagement groove, assuming the primary braking force. The synchronously triggered plug-in post inserts into the track socket, creating a secondary rigid constraint. Even if the hook accidentally unhooks or deforms due to excessive force, the plug-in post still engages with the socket to prevent the basket from sliding further. This "double insurance" design reduces the probability of anti-fall failure to almost zero, making it particularly suitable for harsh scenarios such as heavy loads of tens of tons of scrap steel and high-frequency operations.

[0019] The present invention can avoid the problem that the constraint of a single hook and a snap-fit ​​groove can only prevent the basket car from sliding down the track longitudinally through the provision of a second anti-fall auxiliary component, but cannot limit the lateral shaking or tipping of the basket car, especially when it is overloaded or the track is uneven. The second anti-fall auxiliary component prevents the basket car from sliding down through longitudinal constraint, the cooperation of the hook and the snap-fit ​​groove; lateral constraint, the upper clamping block and the lower clamping block apply clamping force from both sides of the track to suppress the lateral swing or derailment of the basket car; vertical constraint, the clamping force of the upper and lower clamping blocks is transmitted to the supporting rail sleepers through the track, dispersing the vertical impact force and preventing local deformation of the track due to excessive force. This three-dimensional constraint system completely restricts the freedom of the basket car when falling, and is particularly suitable for handling complex working conditions such as "falling accompanied by shaking or tipping", greatly reducing the risk of derailment.

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0022] An embodiment according to the present invention is shown in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 4A safety anti-falling control device for a scrap steel basket cart includes a basket cart assembly 1, which includes a support frame 103. An anti-falling control assembly 4 is provided at the middle position of the lower end of the support frame 103. The anti-falling control assembly 4 includes a fixed hydraulic cylinder 401 fixedly installed at the middle position of the lower end of the support frame 103. A connecting rod 402 is slidably installed at the bottom end of the fixed hydraulic cylinder 401. An assembly seat 404 is fixedly installed at the bottom end of the connecting rod 402. A rotating shaft 405 passes through the middle position of the bottom end of the assembly seat 404. Hooks 406 are fixedly installed on the outer walls of both ends of the rotating shaft 405. A track 2 is provided below the basket car assembly 1, and a supporting sleeper 3 is fixedly installed at the lower end of the track 2. A buckling groove 407 that matches the hook 406 is provided on the side wall of the supporting sleeper 3. The anti-fall control assembly 4 also includes a plug body 403 slidably installed inside the fixed hydraulic cylinder 401. The middle position of the lower end of the plug body 403 is fixedly connected to the connecting rod 402. The outer wall of the fixed hydraulic cylinder 401 is penetrated by a connecting delivery pipe 6 located below the plug body 403. The output end of the connecting delivery pipe 6 is connected to the first anti-fall auxiliary assembly 7 and the second anti-fall auxiliary assembly 8; A motor base 501 is fixedly mounted on one end of the assembly base 404, a control motor 5 is fixedly mounted on the lower end of the motor base 501, and the output end of the control motor 5 is fixedly connected to the rotating shaft 405. The basket trolley assembly 1 also includes a shock-absorbing spring 102 fixedly mounted on the bottom of both ends of the support frame 103, a carrier frame 101 is fixedly mounted on the outside of the bottom end of the shock-absorbing spring 102, a carrier basket 104 is mounted in the middle position of the upper end of the support frame 103, and wheel axles 105 are mounted on both ends of the carrier frame 101, and track wheels 106 are rotatably mounted on both ends of the wheel axle 105.

[0024] By adopting the above technical solution, when in use, a large amount of scrap steel can be loaded through the provided load basket 104, and the support frame 103 can support and load the load basket 104. The load frame 101 and the shock-absorbing spring 102 can support and buffer the load basket 104. At the same time, the track wheel 106 and the wheel axle 105 can support the load frame 101, and enable the load basket 104 to move on the track 2. The driving mechanism provides power for the operation of the material basket car to ensure that it can travel on the track 2 at a predetermined speed and direction. The support rail sleeper 3 provided can provide support for the track 2. When the basket car assembly 1 falls, the basket car assembly 1 will slide down on the inclined track 2. When the basket car assembly 1 slides down, the hook 406 rotates through the rotating shaft 405 It is installed on the assembly seat 404. It should be noted that the size of the hook 406 is larger than the size between the assembly seat 404 and the upper end of the supporting rail sleeper 3. In this way, when the basket car assembly 1 slides down, the hook 406 can hook the snap-fitting groove 407 on the supporting rail sleeper 3, thereby realizing the hooking safety protection treatment of the basket car falling. The size of the hook 406 is larger than the gap between the assembly seat 404 and the supporting rail sleeper 3. From the physical size, it is guaranteed that as long as the basket car slides down, the hook 406 will inevitably contact and hook the snap-fitting groove 407. When the size of the hook 406 is larger than the gap, there is no need to rely on complex triggering mechanisms such as springs and sensors. Only through the inertia or gravity of the basket car sliding down, the hook 406 can naturally droop and quickly contact the supporting rail sleeper 3, and directly snap into the snap-fitting groove 407. This design does not require complex "precision triggering". Components such as sensors and hydraulic drive devices can achieve fall prevention only by matching mechanical dimensions. They have a simple structure and reduce failure points, such as no aging of electronic components and leakage of hydraulic pipelines. They are suitable for the scrap steel workshop environment with high dust and vibration. During maintenance, it is only necessary to check whether the hook 406 is deformed and the locking groove 407 is worn. There is no need to calibrate precision components, which reduces labor and time costs and ensures that the device is in an effective state for a long time.

[0025] When the hook 406 is engaged with the engaging groove 407, the hook 406 will pull the connecting rod 402 downward through the rotating shaft 405 and the assembly seat 404, so that the plug body 403 can move downward, thereby squeezing the liquid inside the fixed hydraulic cylinder 401. By squeezing the liquid inside the fixed hydraulic cylinder 401, the oil inside the fixed hydraulic cylinder 401 can flow into the first anti-falling auxiliary component 7 and the second anti-falling auxiliary component 8 through the connecting delivery pipe 6; when the basket trolley assembly 1 moves downward normally, the control motor 5 is started, and the control motor 5 is energized to drive the rotating shaft 405 to rotate. The rotation of the rotating shaft 405 can drive the hook 406 fixed thereon to rotate, so that the hook 406 and the assembly seat 404 are in a parallel state, which can avoid the influence of the hook 406 on the movement of the device when the basket trolley assembly 1 is retreating. When the basket trolley assembly 1 climbs the slope to feed materials, the control motor 5 does not control the hook 406, so that the hook 406 and the side of the supporting rail sleeper 3 are in an overlapping state.

[0026] Specifically, such as Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the first anti-fall auxiliary component 7 includes a fixed block 701 fixedly mounted on the bottom end of one end of the carrier 101, a socket 703 is fixedly mounted on the side wall of the fixed block 701 close to the track 2, an oil chamber 704 is defined inside the socket 703, a plug post 705 is slidably mounted inside the oil chamber 704, and a socket 702 that matches the plug post 705 is defined on one side edge of the track 2; The second anti-fall auxiliary component 8 includes an assembly frame 801 fixedly mounted at the bottom end of the middle position of the carrier frame 101, an oil channel 802 is provided inside the assembly frame 801, the upper end of the oil channel 802 is connected to the first connecting channel 803, and the bottom end of the oil channel 802 is connected to the second connecting channel 806, an upper clamping seat 804 is fixedly installed on the upper end of the side wall of the assembly frame 801, a first control oil chamber 810 is provided at the inner bottom end of the upper clamping seat 804, an upper clamping block 805 is slidably installed inside the first control oil chamber 810, a lower clamping seat 807 is fixedly installed on the lower end of the side wall of the assembly frame 801, a second control oil chamber 808 is provided at the inner upper end of the lower clamping seat 807, and a lower clamping block 809 is slidably installed inside the second control oil chamber 808.

[0027] By adopting the above technical solution, when in use, when the oil inside the fixed hydraulic cylinder 401 flows into the first anti-falling auxiliary component 7 and the second anti-falling auxiliary component 8 through the connecting delivery pipe 6, the oil in the connecting delivery pipe 6 will flow into the oil chamber 704 inside the socket 703, which can increase the oil in the oil chamber 704, so that the oil can push the plug-in column 705 to slide upward in the oil chamber 704, so that the plug-in column 705 can be inserted into the corresponding socket 702, so that the falling device can be blocked and prevented from falling through the socket 702 on the track 2. In this design of "hook 406 engaging to trigger hydraulic auxiliary braking", the hook 406 drives the hydraulic system to insert the plug-in column 705 into the socket 702. Through the synergistic effect of mechanical hooking and hydraulic auxiliary braking, "double protection + force optimization + buffering energy absorption" is achieved. The advantages of this design are multiple: hook 406 preferentially engages with engagement slot 407, providing the primary braking force. Simultaneously, latch 705 engages socket 702, creating a secondary rigid constraint. Even if hook 406 accidentally becomes unhooked or deforms due to excessive force, latch 705 retains its engagement with socket 702, preventing the basket from sliding further. This "double insurance" design reduces the probability of anti-fall failure to near zero, making it particularly suitable for harsh environments such as those with heavy loads of tens of tons of scrap steel and high-frequency operations.

[0028] When the oil flowing into the connecting pipe 6 flows into the oil channel 802 inside the assembly frame 801, the oil inside the oil channel 802 flows into the first control oil cavity 810 and the second control oil cavity 808 through the first connecting channel 803 and the second connecting channel 806 respectively, and the increase of the oil in the first control oil cavity 810 and the second control oil cavity 808 can push the upper clamping block 805 and the lower clamping block 809 to move in the upper clamping seat 804 and the lower clamping seat 807, so that the side wall of the track 2 can be clamped and fixed by the upper clamping block 805 and the lower clamping block 809, thereby further achieving the effect of auxiliary anti-falling. The auxiliary anti-falling design of "hydraulic drive clamping track 2" significantly improves the reliability and safety of the anti-falling control device through the three mechanisms of multi-directional constraint, flexible buffering and self-adaptive clamping. The setting of the second anti-falling auxiliary assembly 8 can avoid the problem that the single hook 406 and the buckling groove 407 can only prevent the basket car from sliding downward along the track 2 in longitudinal constraint, but cannot limit the lateral shaking or tilting of the basket car, especially when the load is heavy or the track 2 is uneven. The second anti-falling auxiliary assembly 8 prevents sliding downward through longitudinal constraint and the cooperation of the hook 406 and the buckling groove 407; the lateral constraint is that the clamping force of the upper clamping block 805 and the lower clamping block 809 is applied from both sides of the track 2 to suppress the lateral swinging or derailment of the basket car; the vertical constraint is that the clamping force of the upper clamping block 805 and the lower clamping block 809 is transmitted to the support rail sleeper 3 through the track 2 to disperse the impact force in the vertical direction and avoid local deformation of the track 2 due to excessive force. This three-dimensional constraint system completely limits the freedom of the basket car when it falls, especially suitable for handling complex working conditions such as "falling with shaking or tilting", greatly reducing the risk of derailment.

[0029] Specifically, as shown in Figures 1 to 6 the use method of the safety anti-falling control device of the scrap steel basket car, comprising the following steps: S1: buckling anti-falling: through the inertia or gravity of the basket car sliding downward, the hook 406 can naturally droop and quickly contact the support rail sleeper 3, directly entering the buckling groove 407, and achieving anti-falling through mechanical size matching; S2, plug-in anti-falling: the hook 406 drives the hydraulic system to insert the plug-in column 705 into the plug-in hole 702, realizing the multiple anti-falling effects of "double protection + force optimization + buffering energy absorption" through the synergistic effect of mechanical hooking and hydraulic auxiliary braking; S3, clamping anti-falling: the second anti-falling auxiliary assembly 8 has a three-dimensional constraint system of longitudinal, lateral and vertical constraints, which completely limits the freedom of the basket car when it falls, reducing the risk of derailment.

[0030] Working principle: When in use, the supporting basket 104 can be used to load a large amount of scrap steel, and the supporting frame 103 can support the supporting basket 104. The supporting frame 101 and the shock-absorbing spring 102 can support and buffer the supporting basket 104. At the same time, the track wheel 106 and the wheel axle 105 can support the supporting frame 101 and make the supporting basket 104 move on the track 2. The driving mechanism provides power for the operation of the basket car to ensure that it can move on the track at a predetermined speed and direction. 2, the support rail 3 can provide support for the track 2. When the basket car assembly 1 falls, the basket car assembly 1 will slide down on the inclined track 2. When the basket car assembly 1 slides down, the hook 406 is rotated and installed on the assembly seat 404 through the rotating shaft 405. It should be noted that the size of the hook 406 is larger than the size between the assembly seat 404 and the upper end of the support rail sleeper 3. In this way, when the basket car assembly 1 slides down, the hook 406 can hook the buckling groove 407 on the support rail sleeper 3, thereby To achieve a hook safety protection treatment for the basket car falling, when the hook 406 is fastened with the fastening groove 407, the hook 406 will pull the connecting rod 402 downward through the rotating shaft 405 and the assembly seat 404, so that the plug body 403 can move downward, thereby squeezing the liquid inside the fixed hydraulic cylinder 401. By squeezing the liquid inside the fixed hydraulic cylinder 401, the oil inside the fixed hydraulic cylinder 401 can flow into the first anti-falling auxiliary component 7 and the second anti-falling auxiliary component 8 through the connecting delivery pipe 6; When the car assembly 1 moves downward normally, the control motor 5 is started. When the control motor 5 is energized, it can drive the rotating shaft 405 to rotate. The rotation of the rotating shaft 405 can drive the hook 406 fixed thereon to rotate, so that the hook 406 and the assembly seat 404 are in a parallel state. This can avoid the influence of the hook 406 on the movement of the device when the basket car assembly 1 is retreating. When the basket car assembly 1 climbs the slope to feed materials, the control motor 5 does not control the hook 406, so that the hook 406 is in an overlapping state with the side of the supporting rail sleeper 3; When the oil inside the fixed hydraulic cylinder 401 flows into the first anti-falling auxiliary component 7 and the second anti-falling auxiliary component 8 through the connecting delivery pipe 6, the oil in the connecting delivery pipe 6 will flow into the oil chamber 704 inside the socket 703, so that the oil in the oil chamber 704 can be increased, so that the oil can push the plug column 705 to slide upward in the oil chamber 704, so that the plug column 705 can be inserted into the corresponding socket 702, so that the falling device can be blocked and prevented from falling through the socket 702 on the track 2. When the oil in the connecting delivery pipe 6 flows into the inside of the assembly frame 801 When the upper clamping block 805 and the lower clamping block 809 are connected to the oil channel 802, the oil inside the oil channel 802 will flow into the first control oil chamber 810 and the second control oil chamber 808 through the first connecting channel 803 and the second connecting channel 806 respectively. By increasing the oil in the first control oil chamber 810 and the second control oil chamber 808, the upper clamping block 805 and the lower clamping block 809 can be pushed to move in the upper clamping seat 804 and the lower clamping seat 807, so that the side wall of the track 2 can be clamped and fixed by the upper clamping block 805 and the lower clamping block 809, thereby further achieving the effect of auxiliary anti-falling treatment.

[0031] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
