Abstract
Description
Technical Field
[0001] This application relates to the field of steel processing equipment technology, and in particular to a device for detecting the positioning of a sintering trolley. Background Technology
[0002] During the sintering process of steel, the sintering raw materials are loaded onto a sintering trolley and run along a track. After passing through processes such as preheating, ignition, sintering, and cooling, the resulting steel raw materials are transported to the tipping point. The tipping device then dumps the ironmaking raw materials loaded in the trolley to a designated location.
[0003] The existing sintering machine uses sensors to detect when the trolley reaches the tipping position, and then controls the tipping device to start, so that the ironmaking raw materials loaded in the trolley are dumped to the designated position.
[0004] When the aforementioned trolley arrival detection equipment is in use, the high temperature and high dust concentration in the sintering workshop result in a short sensor lifespan and interference with the detection results. To ensure that the trolley has reached the tipping position when tipping is performed, a tipping device is set to start with a delay, which greatly affects the working time of steel sintering and reduces the efficiency of steel sintering. Summary of the Invention
[0005] To improve the efficiency of steel sintering, this application provides a device for detecting the positioning of the sintering trolley.
[0006] This application provides a device for detecting the positioning of a sintering trolley, which adopts the following technical solution:
[0007] A device for detecting the arrival position of a sintering trolley includes a track, a trolley, a tipping assembly, a control assembly, and a detection assembly. The trolley moves along the track and includes a hopper for loading steel raw materials. The tipping assembly is disposed on the track and is used to tip the hopper. The control assembly is disposed on the track and is used to control the working state of the tipping assembly. The detection assembly is disposed on the track and is used to perform detection after the trolley reaches the tipping position and to adjust the working state of the control assembly.
[0008] By adopting the above technical solution, during the sintering process of steel, when the trolley moves along the track to the tipping position under the action of the pusher, the detection component promptly adjusts the working state of the control component when the trolley reaches the tipping position, so that the tipping component starts working and tipps the hopper, pouring the steel raw materials loaded in the hopper out to the designated position. This ensures that the trolley tipps in time when it reaches the tipping position, avoiding unnecessary waste of time and thus improving the efficiency of steel sintering.
[0009] Optionally, the detection assembly includes a detection telescopic rod and a first spring; the fixed end of the detection telescopic rod is fixedly disposed on the track; the movable end of the detection telescopic rod divides the fixed end of the detection telescopic rod into a detection rod-containing cavity and a detection rodless cavity; the first spring is disposed in the detection rodless cavity, and its two ends are fixedly connected to the fixed end of the detection telescopic rod and the movable end of the detection telescopic rod, respectively.
[0010] By adopting the above technical solution, when the trolley runs along the track to the point of nearing the tipping position during the sintering process of steel, the trolley comes into contact with the movable end of the detection telescopic rod. As the trolley moves forward, the movable end of the detection telescopic rod is compressed to overcome the first spring and retract. Through the mechanical structure, the trolley can be detected after it reaches the tipping position. This method has a long service life and accurate detection results.
[0011] Optionally, the trolley further includes a chassis located at the bottom of the hopper, with one side of the hopper hinged to the chassis; the tipping assembly includes a hydraulic telescopic rod, a liquid storage tank, a first connecting pipe, a hydraulic pump, and a return pipe; the fixed end of the hydraulic telescopic rod is fixedly mounted on the track; the movable end of the hydraulic telescopic rod divides the fixed end of the hydraulic telescopic rod into a hydraulic rod-type chamber and a hydraulic rodless chamber; the liquid storage tank is mounted on the track and is pre-filled with liquid; both ends of the first connecting pipe are connected to the hydraulic rodless chamber and the interior of the liquid storage tank, respectively; the hydraulic pump is mounted on the first connecting pipe; both ends of the return pipe are connected to the hydraulic rodless chamber and the liquid storage tank, respectively; an electric valve is installed on the return pipe; a discharge assembly is provided on the hopper to discharge the steel raw material in the hopper.
[0012] By adopting the above technical solution, when the trolley moves to the tipping position and tipes the hopper, the liquid in the storage tank enters the hydraulic rodless chamber through the first connecting pipe under the action of the hydraulic pump, thereby pushing the hydraulic telescopic rod to extend and thus lifting the hopper upward to tip it. When the hopper rotates to the preset angle, the steel raw material in the hopper is discharged to the designated position through the discharge component, thus realizing the discharge of the steel raw material in the hopper.
[0013] Optionally, the control component includes a socket, a plug, and a first adjusting component; the socket is fixedly mounted on the track; the plug is slidably connected to the track and is used in conjunction with the socket; when the plug is inserted into the socket, the hydraulic pump starts and the electric valve closes; the first adjusting component is mounted on the track and is used to adjust the relative position of the plug and the socket.
[0014] By adopting the above technical solution, when the trolley moves to the tipping position and tipps the hopper, the first adjusting component adjusts the plug to slide towards the socket. When the plug is inserted into the socket, the hydraulic pump starts and the electric valve closes. By controlling the working state of the hydraulic pump, the working state of the tipping component is controlled.
[0015] Optionally, a limiting groove is formed on the track; a limiting component is provided on the track; the limiting component includes a movable plate, a limiting telescopic rod, a second spring, and a second connecting pipe; the movable plate is horizontally disposed at the opening of the limiting groove and is slidably connected to the track; the limiting telescopic rod is vertically disposed in the limiting groove, the fixed end of the limiting telescopic rod is fixedly connected to the track, and the movable end of the limiting telescopic rod is fixedly connected to the movable plate; the movable end of the limiting telescopic rod divides the fixed end of the limiting telescopic rod into a limiting rod cavity and a limiting rodless cavity; the second spring is located in the limiting rodless cavity, and its two ends are fixedly connected to the movable end of the limiting telescopic rod and the fixed end of the limiting telescopic rod, respectively; one end of the second connecting pipe communicates with the limiting rodless cavity, and liquid is pre-filled in the limiting rodless cavity; the detection component further includes a second adjusting component, which is used to adjust the communication state of the two ends of the second connecting pipe.
[0016] By adopting the above technical solution, when the trolley reaches the tipping position during the sintering process of steel, the second adjusting component connects the two ends of the second connecting pipe, allowing the liquid in the limit rodless cavity to be discharged through the second connecting pipe. This causes the limit telescopic rod to retract, and under the weight of the trolley, it presses down on the movable plate. The movable plate slides downward, causing the wheels of the trolley to move downward and be fixed in the limit groove. This achieves the limit and fixation of the trolley, ensuring that the trolley tipps at the tipping position and preventing the steel raw material from not being discharged to the designated location. It also prevents the trolley from shaking during tipping, which could cause the steel raw material to not be discharged to the designated location.
[0017] Optionally, the first adjusting component includes a control telescopic rod and a third spring; the fixed end of the control telescopic rod is fixedly connected to the track, and the movable end of the control telescopic rod is fixedly connected to the plug; the fixed end of the control telescopic rod divides the movable end of the control telescopic rod into a control rod cavity and a control rodless cavity; one end of the second connecting pipe away from the limiting telescopic rod is connected to the control rodless cavity, and both the second connecting pipe and the control rodless cavity are pre-filled with liquid; the third spring is located in the control rodless cavity, and its two ends are fixedly connected to the fixed end of the control telescopic rod and the movable end of the control telescopic rod, respectively.
[0018] By adopting the above technical solution, when the trolley moves to the tipping position and tipps the hopper, the liquid discharged from the limit rodless chamber enters the control rodless chamber through the second connecting pipe, causing the control telescopic rod to extend, thereby driving the plug to slide closer to the socket, thus realizing the adjustment of the positional relationship between the plug and the socket.
[0019] Optionally, the control component further includes an elastic element, a third connecting pipe, and a fourth connecting pipe; the elastic element is fixedly mounted on the track and has a hollow structure; the two ends of the third connecting pipe are respectively connected to the interior of the elastic element and the control rodless cavity; the two ends of the fourth connecting pipe are respectively connected to the limiting rod cavity and the hydraulic rod cavity; liquid is pre-filled inside the elastic element, the limiting rod cavity, the hydraulic rod cavity, and the fourth connecting pipe.
[0020] By adopting the above technical solution, during the sintering process of steel, the amount of steel raw material loaded in the hopper varies each time, resulting in different lengths of retraction of the limiting telescopic rod when the trolley reaches the tipping position. The more steel raw material loaded in the hopper, the longer the retraction length of the limiting telescopic rod, the larger the volume of the limiting rod cavity, the more liquid in the hydraulic rod cavity enters the limiting rod cavity through the fourth connecting pipe, the longer the hydraulic telescopic rod can extend, and the greater the angle at which the hopper rotates upward around its hinge axis with the chassis under the push of the hydraulic telescopic rod. The faster the steel raw material in the hopper is discharged, the shorter the time required for steel raw material discharge is shortened without wasting energy, avoiding wasted working hours and thus improving the sintering efficiency of steel.
[0021] Optionally, the second adjusting component includes an adjusting telescopic rod, a fourth spring, and a fifth connecting pipe; the fixed end of the adjusting telescopic rod is fixedly connected to the track, and the movable end of the adjusting telescopic rod is inserted into the second connecting pipe, the movable end of the adjusting telescopic rod dividing the fixed end of the adjusting telescopic rod into an adjusting rod cavity and an adjusting rodless cavity; the fourth spring is located in the adjusting rodless cavity, and its two ends are fixedly connected to the fixed end of the adjusting telescopic rod and the movable end of the adjusting telescopic rod, respectively; the two ends of the fifth connecting pipe are respectively connected to the adjusting rod cavity and the detecting rodless cavity; liquid is pre-filled in the fifth connecting pipe, the detecting rodless cavity, and the adjusting rod cavity.
[0022] By adopting the above technical solution, when the trolley moves to the tipping position during the sintering process of steel, the liquid in the rodless detection chamber enters the regulating rod chamber through the fifth connecting pipe due to the contraction of the detection telescopic rod, causing the regulating telescopic rod to contract and the two ends of the second connecting pipe to be in a connected state, thereby realizing the adjustment of the connection state of the two ends of the second connecting pipe.
[0023] Optionally, one side wall of the hopper is a hinged plate, and the top of the hinged plate is hinged to the hopper; the discharge assembly includes a first magnetic strip and a second magnetic strip, the first magnetic strip is fixedly connected to the hinged plate, the second magnetic strip is fixedly connected to the hopper, and the first magnetic strip and the second magnetic strip have mutual attraction.
[0024] By adopting the above technical solution, when the hopper is tipped over, under the state of the hydraulic telescopic rod, the hopper rotates upward around its own hinge axis with the chassis. Due to its own weight, the steel raw material in the hopper overcomes the mutual attraction between the first and second magnetic strips, causing the hinge plate to open and then being discharged to the designated position, thus realizing the discharge of the steel raw material in the hopper.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. By setting up detection and control components, during the sintering process of steel, when the trolley moves along the track to the tipping position under the action of the pusher, the detection component detects that the trolley has reached the tipping position and adjusts the working state of the control component in time, so that the tipping component starts to work and tip the hopper, pouring the steel raw material loaded in the hopper out to the designated position. This ensures that the trolley tipps in time when it reaches the tipping position, avoiding unnecessary waste of time and thus improving the efficiency of steel sintering.
[0027] 2. By setting up control components, the more steel raw materials loaded in the hopper, the longer the hydraulic telescopic rod extends. Under the push of the hydraulic telescopic rod, the greater the angle at which the hopper rotates upward around its hinge axis with the chassis, the faster the steel raw materials in the hopper are discharged. While ensuring no energy waste, the time required for steel raw material discharge is shortened, avoiding wasted working hours, thereby improving the sintering efficiency of steel.
[0028] 3. By setting a limiting component, when the trolley reaches the tipping position during the sintering process of steel, the wheels of the trolley move downward and are fixed in the limiting groove, thereby limiting and fixing the trolley. This ensures that the trolley tipps over at the tipping position, preventing the steel raw material from not being discharged to the designated location. At the same time, it also prevents the trolley from shaking during tipping, which would cause the steel raw material to not be discharged to the designated location. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0044] This application discloses a device for detecting the positioning of a sintering trolley 2. (Refer to...) Figure 1A device for detecting the arrival position of a sintering trolley 2 includes a track 1, a trolley 2, a tipping assembly 3, a control assembly 4, and a detection assembly 5. The track 1 is horizontally positioned, and the trolley 2 moves along the track 1. The trolley 2 includes a hopper 21 for loading steel raw materials. The tipping assembly 3 is mounted on the track 1 and is used to tip the hopper 21. The control assembly 4 is mounted on the track 1 and is used to control the working state of the tipping assembly 3. The detection assembly 5 is mounted on the track 1 and is used to detect whether the trolley 2 has reached the tipping position and to adjust the working state of the control assembly 4.
[0045] During the sintering process of steel, the trolley 2 runs along the track 1 under the action of the pusher. When it reaches the tipping position, the detection component 5 detects that the trolley 2 has reached the tipping position and adjusts the working state of the control component 4 so that the tipping component 3 starts to work, tipping the hopper 21 and pouring the steel raw materials loaded in the hopper 21 out to the designated position.
[0046] Reference Figure 2 The trolley 2 includes a chassis 22 and a hopper 21. The chassis 22 is horizontally positioned, and the wheels of the trolley 2 are connected to the chassis 22. The hopper 21 has a top-opening structure and is horizontally positioned above the chassis 22. One side of the hopper 21 is hinged to the chassis 22, and the hinge axis is horizontally positioned. The side wall of the hopper 21 near the designated position is a hinge plate 211, the top of which is hinged to the hopper 21, and the hinge axis is horizontally positioned.
[0047] Reference Figure 3 The hopper 21 is equipped with a discharge assembly 6, which includes a first magnetic strip 61 and a second magnetic strip 62. The first magnetic strip 61 is fixedly connected to the hinge plate 211, and the second magnetic strip 62 is fixedly connected to the hopper 21. The first magnetic strip 61 and the second magnetic strip 62 are attracted to each other.
[0048] When the trolley 2 reaches the tipping position, under the action of the tipping assembly 3, the hopper 21 rotates upward around its own hinge axis with the chassis 22. Due to its own weight, the steel raw material in the hopper 21 overcomes the mutual attraction between the first magnetic strip 61 and the second magnetic strip 62, causing the hinge plate 211 to open and then be discharged to the designated position.
[0049] Reference Figure 4The track 1 has limit grooves 11 on both sides. A limit assembly 7 is installed on the track 1, comprising a movable plate 71, a limit telescopic rod 72, a second spring 73, and a second connecting pipe 74. The movable plate 71 is horizontally positioned at the opening of the limit groove 11 and slidably connected to the track 1, with its sliding axis vertically positioned. The limit telescopic rod 72 is vertically positioned within the limit groove 11, with its fixed end fixedly connected to the track 1 and its movable end fixedly connected to the movable plate 71. The movable end of the limit telescopic rod 72 divides its fixed end into a limit rod cavity 721 and a limit rodless cavity 722, with the limit rod cavity 721 located above the limit rodless cavity 722. The second spring 73 is vertically positioned within the limit rodless cavity 722, with both ends fixedly connected to the movable end and the fixed end of the limit telescopic rod 72, respectively. One end of the second connecting pipe 74 is connected to the limiting rodless cavity 722, which is pre-filled with liquid.
[0050] Reference Figure 5 and Figure 6 The detection assembly 5 includes a detection telescopic rod 51, a first spring 52, and a second adjusting component 53. The detection telescopic rod 51 is vertically positioned, with its fixed end fixedly mounted on the track 1, and its movable end having a wedge-shaped top. The movable end of the detection telescopic rod 51 divides its fixed end into a detection rod cavity 511 and a detection rodless cavity 512, with the detection rod cavity 511 located above the detection rodless cavity 512. The first spring 52 is vertically positioned within the detection rodless cavity 512, and its two ends are fixedly connected to the fixed end and the movable end of the detection telescopic rod 51, respectively.
[0051] Reference Figure 6 The second adjusting component 53 includes an adjusting telescopic rod 531, a fourth spring 532, and a fifth connecting pipe 533. The adjusting telescopic rod 531 is vertically installed inside the track 1. The fixed end of the adjusting telescopic rod 531 is fixedly connected to the track 1, and the movable end of the adjusting telescopic rod 531 is inserted into the second connecting pipe 74. The movable end of the adjusting telescopic rod 531 divides the fixed end of the adjusting telescopic rod 531 into an adjusting rod cavity 5311 and an adjusting rodless cavity 5312, with the adjusting rod cavity 5311 located below it. The fourth spring 532 is vertically installed inside the adjusting rodless cavity 5312, and its two ends are fixedly connected to the fixed end and the movable end of the adjusting telescopic rod 531, respectively. The two ends of the fifth connecting pipe 533 are connected to the adjusting rod cavity 5311 and the detecting rodless cavity 512, respectively. Liquid is pre-filled inside the fifth connecting pipe 533, the detecting rodless cavity 512, and the adjusting rod cavity 5311.
[0052] During the sintering process of steel, when the trolley 2 runs along the track 1 to a position close to the tipping point, the side wall of the chassis 22 abuts against the top of the movable end of the detection telescopic rod 51. Since the top of the movable end of the detection telescopic rod 51 is wedge-shaped, as the trolley 2 moves forward, the movable end of the detection telescopic rod 51 is squeezed to overcome the first spring 52 and moves downward, so that the liquid in the detection rodless chamber 512 enters the regulating rod chamber 5311 through the fifth connecting pipe 533. The regulating telescopic rod 531 is squeezed to overcome the fourth spring 532 and contracts, so that the two ends of the second connecting pipe 74 are in a connected state.
[0053] When the two ends of the second connecting pipe 74 are in a connected state, due to the gravity of the trolley 2, the trolley 2 presses down on the movable plate 71, causing the movable end of the limiting telescopic rod 72 to slide down against the second spring 73, so that the liquid in the limiting rodless cavity 722 is discharged through the second connecting pipe 74, and the wheel of the trolley 2 is fixed in the limiting groove 11.
[0054] Reference Figure 5 The tipping assembly 3 includes a hydraulic telescopic rod 31, a liquid storage tank 32, a first connecting pipe 33, a hydraulic pump 34, and a return pipe 35. The hydraulic telescopic rod 31 is vertically installed inside the track 1. The fixed end of the hydraulic telescopic rod 31 is fixedly connected to the track 1. An elastic pad is provided at the top of the movable end of the hydraulic telescopic rod 31. The movable end of the hydraulic telescopic rod 31 divides the fixed end of the hydraulic telescopic rod 31 into a hydraulic rod-type chamber 311 and a hydraulic rodless chamber 312, with the hydraulic rod-type chamber 311 located above the hydraulic rodless chamber 312. The liquid storage tank 32 is installed inside the track 1 and contains oil. The two ends of the first connecting pipe 33 are connected to the hydraulic rodless chamber 312 and the liquid storage tank 32, respectively. The hydraulic pump 34 is installed on the first connecting pipe 33 and is used to transport the liquid in the liquid storage tank 32 to the hydraulic rodless chamber 312. The two ends of the return pipe 35 are connected to the hydraulic rodless chamber 312 and the liquid storage tank 32, respectively. An electric valve 351 is installed on the return pipe 35.
[0055] Reference Figure 6 The control component 4 includes a socket 41, a plug 42, and a first adjusting component 43. The socket 41 is fixedly installed inside the track 1 and has a slot. The plug 42 is located inside the track 1 and is slidably connected to the track 1, with its sliding axis aligned with the length direction of the slot. The plug 42 is used in conjunction with the socket 41. When the plug 42 is inserted into the socket 41, the hydraulic pump 34 starts and the electric valve 351 closes. When the plug 42 moves away from the socket 41, the hydraulic pump 34 stops working and the electric valve 351 opens.
[0056] Reference Figure 6The first adjusting component 43 includes a control telescopic rod 431 and a third spring 432. The control telescopic rod 431 is horizontally disposed inside the track 1, and the direction of the extension axis of the control telescopic rod 431 is the same as the direction of the sliding axis of the plug 42. The fixed end of the control telescopic rod 431 is fixedly connected to the track 1, and the movable end of the control telescopic rod 431 is fixedly connected to the plug 42. The fixed end of the control telescopic rod 431 divides the movable end of the control telescopic rod 431 into a control rod cavity 4311 and a control rodless cavity 4312, with the control rod cavity 4311 located between the control rodless cavity 4312 and the plug 42. The end of the second connecting pipe 74 away from the limiting telescopic rod 72 is connected to the control rodless cavity 4312, and both the second connecting pipe 74 and the control rodless cavity 4312 are pre-filled with liquid. The third spring 432 is located inside the control rodless cavity 4312. The length direction of the third spring 432 is the same as the length direction of the control telescopic rod 431, and its two ends are fixedly connected to the fixed end and the movable end of the control telescopic rod 431, respectively.
[0057] During the sintering process of steel, when the trolley 2 reaches the tipping position, while the wheels of the trolley 2 are fixed in the limiting groove 11, the oil in the limiting rodless chamber 722 enters the control rodless chamber 4312 through the second connecting pipe 74, squeezing the limiting telescopic rod 72 to extend against the third spring 432, thereby driving the plug 42 to slide closer to the socket 41 until the plug 42 is inserted into the socket 41. Then the hydraulic pump 34 starts and the electric valve 351 closes. Under the action of the hydraulic pump 34, the liquid in the storage tank 32 enters the hydraulic rodless chamber 312 through the first connecting pipe 33, thereby pushing the hydraulic telescopic rod 31 to extend. The extended hydraulic telescopic rod 31 lifts the hopper 21 upward to tip it over.
[0058] Reference Figure 2 and Figure 6 The control component 4 also includes an elastic element 44, a third connecting pipe 45, and a fourth connecting pipe 46. The elastic element 44 has a hollow structure and is fixedly installed inside the track 1. The elastic force of the elastic element 44 is greater than the elastic force of the third spring 432. The two ends of the third connecting pipe 45 are connected to the interior of the elastic element 44 and the control rodless cavity 4312, respectively. The two ends of the fourth connecting pipe 46 are connected to the detection rod cavity 511 and the hydraulic rod cavity 311, respectively. Liquid is pre-filled inside the elastic element 44, the detection rod cavity 511, the hydraulic rod cavity 311, and the fourth connecting pipe 46.
[0059] During the sintering process of steel, when the trolley 2 reaches the tipping position, the length of the retraction of the limiting telescopic rod 72 varies each time the amount of steel raw material loaded in the hopper 21 is different. The more steel raw material loaded in the hopper 21, the longer the retraction length of the limiting telescopic rod 72, the larger the volume of the limiting rod cavity 721, the more liquid in the hydraulic rod cavity 311 enters the limiting rod cavity 721 through the fourth connecting pipe 46, the longer the hydraulic telescopic rod 31 can extend, and the greater the angle at which the hopper 21 rotates upward around its hinge axis with the chassis 22 under the push of the hydraulic telescopic rod 31, the faster the steel raw material in the hopper 21 is discharged.
[0060] The more steel raw materials loaded in the hopper 21, the longer the retracted length of the limiting telescopic rod 72, and the more liquid in the limiting rodless cavity 722 enters the control rodless cavity 4312 through the second connecting pipe 74. Since the elastic force of the elastic element 44 is greater than the elastic force of the third spring 432, the liquid entering the control rodless cavity 4312 first squeezes the movable end of the control telescopic rod 431, causing the control telescopic rod 431 to extend, thereby driving the plug 42 to move closer to the socket 41. When the plug 42 is inserted into the socket 41, the excess liquid enters the elastic element 44 through the third connecting pipe 45, and the elastic element 44 expands.
[0061] The implementation principle of the detection device for the sintering trolley 2 in this embodiment is as follows:
[0062] During the sintering process of steel, when the trolley 2 reaches the tipping position, the movable end of the pressure detection telescopic rod 51 of the chassis 22 moves downward, causing the adjusting telescopic rod 531 to retract, so that the two ends of the second connecting pipe 74 are in a connected state. At this time, the trolley 2 presses the movable plate 71 downward to slide downward, so that the wheels of the trolley 2 are fixed in the limiting groove 11. When the movable plate 71 slides downward, it causes the limiting telescopic rod 72 to retract, so that the liquid in the limiting rodless cavity 722 enters the control rodless cavity 4312, causing the limiting telescopic rod 72 to extend, thereby causing the plug 42 to be inserted into the socket 41. Then the hydraulic pump 34 starts and the electric valve 351 closes. Under the action of the hydraulic pump 34, the liquid in the storage tank 32 enters the hydraulic rodless cavity 312, pushing the hydraulic telescopic rod 31 to extend, and lifting the hopper 21 upward to tip it over.
[0063] When the hopper 21 is tipped over, the hopper 21 rotates upward around its hinge axis with the chassis 22. Due to its own weight, the steel raw material in the hopper 21 overcomes the mutual attraction between the first magnetic strip 61 and the second magnetic strip 62, causing the hinge plate 211 to open and then be discharged to the designated position.
[0064] Since the amount of steel raw materials loaded in the hopper 21 varies each time, the control component 4 is adjusted so that the more steel raw materials loaded in the hopper 21, the longer the hydraulic telescopic rod 31 can extend, the greater the angle at which the hopper 21 rotates upward around its hinge axis with the chassis 22, and the faster the steel raw materials in the hopper 21 are discharged.
[0065] After the steel raw materials in the hopper 21 are discharged, due to the reduction in weight, the limiting telescopic rod 72 extends and resets under the action of the second spring 73. The movable plate 71 is in a horizontal state with the top wall of the track 1. Under the action of the elastic force of the elastic element 44, the liquid inside the elastic element 44 flows into the limiting rodless cavity 722 through the second connecting pipe 74. Then, under the action of the third spring 432, the telescopic rod 431 is controlled to retract and reset, so that the plug 42 moves away from the socket 41. The hydraulic pump 34 stops working, the electric valve 351 opens, and under the action of the gravity of the hopper 21, the liquid in the hydraulic rodless cavity 312 enters the oil storage tank through the return pipe 35. The hydraulic telescopic rod 31 retracts and resets, so that the hopper 21 rotates downward around its hinge axis with the chassis 22 to reset. The trolley 2 moves forward along the track 1 and leaves the tipping position under the action of the pusher.
[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
