Description

Technical Field

[0001] The present invention relates to the field of conveying operation platforms, and particularly to an anti-falling component for a combined conveying operation platform and a control method therefor. Background Art

[0002] A combined conveying operation platform is a multi-functional logistics device composed of multiple combinable components. It can be flexibly assembled according to different operation requirements to adapt to various cargo conveying and handling tasks. In the fields of warehousing, logistics, production, etc., it can effectively improve the conveying efficiency, facilitate adjustment and expansion, meet the requirements of changing operation scenarios, and provide a stable and efficient platform support for material handling.

[0003] In the prior art, during the process of conveying materials by a combined conveying operation platform, for a combined conveying operation platform with a lifting function, when the combined conveying operation platform rises to the highest position for conveying, if the conveyed materials are too heavy, the overweight materials will impose a burden on the combined conveying operation platform, resulting in a risk of falling during the conveying process of the combined conveying operation platform, thereby affecting the normal operation of the combined conveying operation platform. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an anti-falling component for a combined conveying operation platform and a control method therefor.

[0005] In a first aspect, the present invention provides an anti-falling component for a combined conveying operation platform, including a platform, an elevating pit is formed inside the platform, and further includes: A base, fixed to the inner bottom of the elevating pit; An elevating frame, fixed to the top of the base; An elevating platform, fixed to the top of the elevating frame, and the elevating frame is used to drive the elevating platform to move vertically; A weighing and conveying component, installed on the top of the elevating platform, for monitoring the weight of the conveyed materials while conveying the materials; A clamping component, installed between the elevating platform and the platform, for realizing anti-falling protection of the elevating platform by restricting the position of the elevating platform when the elevating platform rises to the highest position; A control unit, used to control the start of the weighing and conveying component and the clamping component; The lifting frame can drive the lifting platform to move vertically. The lifting frame is any lifting frame commonly used in the prior art. After the lifting platform moves upward, it is flush with the top of the platform. The weighing and conveying assembly can convey materials and weigh the conveyed materials during the conveying process, which helps to avoid the situation that the conveyed materials are too heavy, resulting in the extrusion of the lifting platform during the conveying process and the risk of the lifting platform falling. When the lifting platform rises to the highest point and is in the position of conveying materials, the clamping component can clamp the position of the lifting platform, which helps to reduce the risk of the lifting platform falling. And when the lifting platform still has the risk of falling, it can emergently support and protect the lifting platform to prevent the lifting platform from continuing to fall, which helps to achieve the anti-falling protection of the lifting platform, so that the lifting platform can be protected when there is a risk of falling or falling, and it helps to avoid the situation that the lifting platform falls completely downward and causes damage or the materials conveyed above are damaged.

[0006] Preferably, the weighing and conveying assembly includes: Four second connecting frames, symmetrically fixed to both ends of the lifting platform; Four gravity sensors, respectively fixed to the tops of the four second connecting frames; Four first connecting frames, respectively detachably installed on the tops of the four gravity sensors; A conveying platform, fixed to the tops of the four first connecting frames; A number of conveying rollers, all rotatably installed inside the conveying platform, and the materials are conveyed by the rotation of the conveying rollers; A driving member, installed on the side wall of the conveying platform, for driving the conveying rollers to rotate; The second connecting frame can install the gravity sensor. The weight of the materials conveyed on the conveying platform is applied to the first connecting frame, and the gravity sensor can detect the gravity applied by the first connecting frame, so as to detect the weight of the conveyed materials and avoid the situation that the conveyed materials are too heavy and cause falling; The driving member includes a motor, a synchronous chain belt and synchronous gears. The motor drives one of the synchronous gears to rotate. The rotation of the synchronous gear drives all the synchronous gears to rotate through the transmission of the synchronous chain belt. The synchronous gear drives the conveying rollers to rotate, and the conveying rollers can convey the materials after rotation, so as to detect the weight of the conveyed materials while conveying the materials. When it is detected that the conveyed materials are too heavy, the addition of materials is reduced.

[0007] Preferably, the clamping component includes: Two groups of limit insertion rods. Two of the limit insertion rods are in a group, and the two groups of limit insertion rods are symmetrically and movably inserted into the inner parts of the cylindrical grooves at both ends of the lifting platform; Two first cylinders, with two of the first cylinders as a group. The two groups of first cylinders are symmetrically installed at both ends of the lifting platform and drive the respective limit insertion rods to move horizontally. Two anti-falling frames, which are respectively installed at both ends of the platform. Two groups of limit slots, with two of the limit slots as a group. The two groups of limit slots are respectively symmetrically opened on the opposite sides of the two anti-falling frames, and the limit slots are adapted to the limit insertion rods. Two air impact mechanisms, which are respectively installed inside the two anti-falling frames and are used to clean the inside of the limit slots when the limit insertion rods are connected. Two falling trigger mechanisms, which are respectively installed inside the two anti-falling frames and are used to identify the fall of the lifting platform. After the first cylinder is started, it drives the connected limit insertion rod to move, so that the limit insertion rod is inserted into the inside of the limit slot. The air impact mechanism can be triggered when the limit insertion rod is connected, so that the inside of the limit slot is impacted by the airflow during connection, which is beneficial to removing pollutants such as debris accumulated inside the limit slot, and is beneficial to avoiding the situation that the limit slot is blocked and affects the insertion. After the limit insertion rod is connected, it clamps and supports the lifting platform. When the lifting platform still has a falling situation, the falling trigger mechanism is started. After the falling trigger mechanism is started, it further supports the lifting platform. Therefore, when the lifting platform has a falling situation, it can quickly support and protect the lifting platform, which is beneficial to avoiding the situation that the materials conveyed are damaged due to the fall of the lifting platform.

[0008] Preferably, the clamping component further includes: Four straight rods, which are respectively installed inside the respective limit slots. Four discs, which are respectively rotationally connected to the ends of the four straight rods through universal balls. Four groups of pressure sensors, and the four groups of pressure sensors are respectively installed at the ends of the four straight rods in a circumferential array. When the disc is offset and squeezed, some of the pressure sensors in the same group are not stressed. When the limit insertion rod squeezes the disc, the diameter of the end of the limit insertion rod decreases, so that the contact area between the limit insertion rod and the disc is reduced. When the limit insertion rod generates an offset, the limit insertion rod squeezes at the edge of the disc, resulting in the limit insertion rod being offset after being squeezed, so that some of the pressure sensors are not stressed, which can identify the offset of the limit insertion rod, and can give a warning in time when the limit insertion rod generates an offset, to prompt the staff that the lifting platform has an offset, so that the staff can check the lifting platform in time to avoid the situation that the lifting platform continues to be used after being damaged and causes a fall.

[0009] Preferably, the air impulse mechanism comprises: Two second pressure sensors are respectively mounted on the side walls of the two discs of the same anti-fall frame, and when the limit plug rods are connected, the second pressure sensors are pressurized; An air pump installed inside the anti-fall frame; A connecting pipe is fixed inside the anti-fall frame, and the output end of the air pump is connected to the connecting pipe; Two output pipes are respectively embedded and installed on the inner walls of the two limiting grooves, the two output pipes are connected to the connecting pipe, and a plurality of one-way exhaust holes are installed on the two output pipes; After the second pressure sensor is pressurized, it controls the air pump to start, and the air pump delivers gas to the inside of the connecting tube. The gas inside the connecting tube enters the inside of the output tube, and is then quickly discharged from the inside of the output tube through the one-way exhaust hole to form a high-pressure airflow, thereby cleaning the pollutants inside the limit groove through the action of the high-pressure airflow, which helps to avoid the situation where the limit groove is blocked and affects the positioning connection.

[0010] Preferably, the positioning assembly further comprises: Two groups of support platforms, a plurality of the support platforms form one group, and the two groups of support platforms are movably inserted into a plurality of receiving grooves opened on opposite sides of the two anti-fall frames; Two groups of second cylinders are arranged in one-to-one correspondence with the support platforms and are respectively installed inside the corresponding anti-fall frames, and the second cylinders are used to push the corresponding support platforms out of the receiving slots; A plurality of push plates are respectively fixed to the ends of the telescopic rods of the second cylinders, and all the push plates are respectively slidably connected to the inside of the annular slide grooves on the support platforms through sliding contacts; When the lifting platform falls, the fall trigger mechanism is triggered, thereby controlling the second cylinder to start, and the second cylinder pushes the push plate, and the push plate pushes the support platform, so that the support platform is fully extended. The extended support platform can receive the fallen lifting platform, which is helpful to avoid the lifting platform from falling a long distance. When it falls a short distance, it can reduce damage to the transported materials.

[0011] Preferably, the positioning assembly further includes: A plurality of motors, one motor corresponds to one support platform, and the motors are respectively installed inside the two anti-fall frames; A plurality of cross-connecting rods are rotatably mounted inside the two anti-fall frames, and all the motors drive the cross-connecting rods to rotate through output shafts; A plurality of plug-in slots are respectively provided at the ends of the support platforms, and the cross plug-in rods are slidably inserted in the plug-in slots; The radius of the support platform gradually increases from the top to the bottom of the cross-section and is symmetric on both sides. After the support platform rotates, it can lift the object supported on the top. After the motor starts, it can drive the cross-shaped insertion rod to rotate, and the cross-shaped insertion rod drives the support platform to rotate. As a result, the part with an increasing bottom radius after rotation is rotated to the top, so as to lift the lifting platform through the rotation action, so that the falling lifting platform can be lifted again to coincide with the platform under the lifting action, enabling the lifting platform to normally support the weighing and conveying assembly in a short time, thus realizing normal conveying within a short time, and being able to complete the conveying of the continuously conveyed materials through emergency conveying within a short time, which is conducive to reducing the adverse impact of falling on conveying.

[0012] Preferably, the clamping component further includes: A plurality of buffer plates, which are respectively installed on the tops of the respective support platforms; A plurality of elastic support rods, which are respectively fixed inside the respective support platforms, and the tops of all the elastic support rods are respectively connected to the respective buffer plates; A plurality of relief grooves, which are respectively opened on the tops of the respective support platforms, and the relief grooves are adapted to the buffer plates; When the lifting platform falls, during the falling process, it impacts and squeezes the buffer plate. The buffer plate is elastically supported by the elastic support rods. Through the arrangement of the plurality of elastic support rods, part of the impact force of the fall is buffered, which is conducive to reducing the impact generated by the fall and reducing the damage to the equipment and materials caused by the fall.

[0013] Preferably, the fall trigger mechanism includes: A gear, which is rotatably installed inside the anti-fall frame, and the gear is sleeved on the outer ring of one of the straight rods; A first spring, which is fixed between the straight rod corresponding to the gear and the anti-fall frame, and the straight rod and the anti-fall frame are slidably inserted and connected; A thread groove, which is opened on the surface of the straight rod corresponding to the gear, and the thread groove is adapted to the sliding contact of the inner wall of the gear; A threaded rod, which is rotatably installed inside the anti-fall frame; A gear set, which is installed inside the anti-fall frame, and after the gear rotates, it drives the threaded rod to rotate through the gear set; A threaded sleeve, which is threadedly sleeved on the outer ring of the threaded rod and is slidably connected to the anti-fall frame, and a pressing head is fixed at the bottom of the threaded sleeve; A plurality of trigger buttons, which are linearly arrayed and installed inside the anti-fall frame, and the pressing head is used to press the trigger buttons; Two pressing platforms, which are respectively vertically slidably installed at the bottoms of the two limiting grooves; Two second springs are fixed between the pressing table and the anti-falling frame, and a third pressure sensor is fixed at the bottom of the pressing table; After the limit plugging rod moves, it pushes the straight rod to move. After the straight rod moves, it drives the threaded groove to move. Thus, the gear is driven to rotate through the adaptation of the threaded groove and the sliding contact on the inner wall of the gear. After the gear rotates, the threaded rod is driven to rotate through the gear set. After the threaded rod rotates, the threaded sleeve moves. The threaded sleeve drives the pressing head to move, so as to sequentially squeeze the trigger buttons. After the limit plugging rod is completely plugged, the pressing head presses all the trigger buttons. At this time, if the lifting platform falls, after the limit plugging rod is damaged, it disengages from the straight rod, so that the straight rod resets under the elastic action of the first spring, thereby driving the pressing head to reset and move. At this time, due to the fall of the lifting platform, the limit plugging rod is damaged and presses the pressing table, so that the third pressure sensor is pressed. After the third pressure sensor is pressed, when the pressing head presses the trigger buttons in sequence, the second cylinder, the motor and the alarm can be triggered in sequence, so that the support platform can extend and rotate in sequence to support and lift the lifting platform, so as to provide emergency anti-falling protection for the lifting platform.

[0014] In a second aspect, a control method for an anti-falling component of a combined conveying operation platform is provided. The control method includes the following steps: The control unit obtains the falling information from the card position component; The control unit generates protection control information according to the falling information. The protection control information is used to control the card position component to start emergency support protection; The control unit sends the protection control information to the card position component; The control unit obtains the weight information M1 from the weighing and conveying component; The control unit obtains the weight threshold information M0 from the user terminal connected to the control unit, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n; The control unit substitutes the weight information M1, the weight threshold information M0, the constant weight M2, and the safety interval coefficient n into the judgment formula M1 ≤ M2 + M0(1 - n). If the judgment formula is met, the control unit generates safety conveying control information. The safety conveying control information is used to prompt the staff that safe emergency conveying can be carried out in the current state. If the judgment formula is not met, the control unit generates emergency pause control information. The emergency pause control information is used to prompt the staff that an emergency pause is required immediately in the current state; The control unit sends the safety conveying control information or the emergency pause control information to the user terminal; When the lifting platform falls, the clamping component detects the fall and generates fall information, and then sends the fall information to the control unit, so that the control unit obtains the fall information from the clamping component. The control unit generates protection control information according to the fall information and sends the protection control information to the clamping component to control the clamping component to start emergency support protection, so that the clamping component urgently supports and lifts the falling lifting platform to avoid the situation of the large-distance fall of the lifting platform. After the lifting of the lifting platform is completed, the weighing and conveying component monitors the weight of the material to obtain the weight information M1, and then sends the weight information M1 to the control unit, so that the control unit obtains the weight information M1 from the weighing and conveying component. The staff can input the weight threshold information M0, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n through the user terminal. The weight threshold information M0 is the maximum weight threshold for conveying, which is set by the staff according to different equipment. The constant weight M2 is the weight of the weighing and conveying component itself and is a fixed value. The safety interval coefficient n is the weight ratio left between the maximum weight conveyed and the weight threshold information M0 after a fall occurs, so that the control unit can obtain the weight threshold information M0, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n from the user terminal. Then the control unit substitutes the above data into the judgment formula M1 ≤ M2 + M0(1 - n). If the judgment formula is met, the control unit generates safety conveying control information and sends the safety conveying control information to the user terminal. The safety conveying control information is used to prompt the staff that safe emergency conveying can be carried out in the current state, so that when there is a material that needs to be urgently conveyed, the staff does not temporarily shut down the equipment, but urgently conveys the material within a specified time range and shuts down the equipment for maintenance after the conveying is completed. If the judgment formula is not met, the control unit generates emergency pause control information and sends the emergency pause control information to the user terminal. The emergency pause control information is used to prompt the staff that an emergency pause needs to be carried out immediately in the current state, so that when the staff receives the emergency pause control information, they immediately stop the equipment for maintenance because the weight of the material currently conveyed on the weighing and conveying component exceeds the safety value, and further fall may occur if the conveying continues.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the weighing and conveying component, the detection of the weight of the conveyed material is realized while the material is being conveyed. When it is detected that the conveyed material is too heavy, the addition of the material is reduced to avoid the situation of falling caused by the overweight of the conveyed material.

[0016] 2. Through the setting of the clamping component, when the lifting platform still has the risk of falling, it can emergently support and protect the lifting platform to prevent it from continuing to fall, which is conducive to realizing the anti-falling protection of the lifting platform, enabling the lifting platform to be protected when there is a risk of falling or actual falling, and helping to avoid the situation where the lifting platform falls completely downward and causes damage or the materials transported above are damaged.

[0017] 3. Through the setting of the control method, when there are materials that need to be emergently transported after a fall, the staff do not immediately shut down the equipment, but within a specified time range, emergently transport the materials. When the weight of the materials currently being transported on the weighing and conveying component exceeds the safety value, the equipment is immediately emergently paused for maintenance.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0030] As Figures 1 to 10 shown, an anti-falling component for a combined conveying operation platform includes a platform 1. An internal lifting pit 101 is provided in the platform 1, and further includes: A base 102, fixed to the inner bottom of the lifting pit 101; A lifting frame 103, fixed to the top of the base 102; A lifting table 104, fixed to the top of the lifting frame 103. The lifting frame 103 is used to drive the lifting table 104 to move vertically; A weighing and conveying component, installed on the top of the lifting table 104, for monitoring the weight of the conveyed material while conveying the material; A clamping component, installed between the lifting table 104 and the platform 1, for realizing anti-falling protection of the lifting table 104 by limiting the position of the lifting table 104 when the lifting table 104 rises to the highest position; A control unit, used to control the start of the weighing and conveying component and the clamping component; In the prior art, during the process of conveying materials by a combined conveying operation platform, for a combined conveying operation platform with a lifting function, when the combined conveying operation platform rises to the highest position for conveying, if the conveyed material is too heavy, the overweight material will cause a burden on the combined conveying operation platform, resulting in a risk of falling during the conveying process of the combined conveying operation platform, thus affecting the normal operation of the combined conveying operation platform; This embodiment of the present invention can solve the above problems. The specific implementation is as follows. The lifting frame 103 can drive the lifting platform 104 to move vertically. The lifting frame 103 is any lifting frame commonly used in the prior art. After the lifting platform 104 moves upward, it is flush with the top of the platform 1. The weighing and conveying assembly can convey the material and weigh the conveyed material during the conveying process, which helps to avoid the risk of the conveyed material being too heavy, resulting in the extrusion of the lifting platform 104 during the conveying process and the risk of the lifting platform 104 falling. When the lifting platform 104 is lifted to the highest point and is in the position of conveying the material, the clamping component can clamp the position of the lifting platform 104, which helps to reduce the risk of the lifting platform 104 falling. And when the lifting platform 104 still has the risk of falling, it can urgently support and protect the lifting platform 104 to prevent the lifting platform 104 from continuing to fall, which helps to achieve the anti-falling protection of the lifting platform 104, so that the lifting platform 104 can be protected when there is a risk of falling or actual falling, and helps to avoid the situation that the lifting platform 104 falls completely downward and causes damage or the conveyed material above is damaged.

[0031] As an optional embodiment, the weighing and conveying assembly includes: Four second connecting frames 204, symmetrically fixed to both ends of the lifting platform 104; Four gravity sensors 205, respectively fixed to the tops of the four second connecting frames 204; Four first connecting frames 203, respectively detachably installed on the tops of the four gravity sensors 205; The conveying platform 2 is fixed to the tops of the four first connecting frames 203; A plurality of conveying rollers 201 are all rotatably installed inside the conveying platform 2, and the material is conveyed by the rotation of the conveying rollers 201; The driving member 202 is installed on the side wall of the conveying platform 2 and is used to drive the conveying rollers 201 to rotate; The second connecting frame 204 can install the gravity sensor 205. The weight of the material conveyed on the conveying platform 2 is applied to the first connecting frame 203, and the gravity sensor 205 can detect the gravity applied to the first connecting frame 203, so as to detect the weight of the conveyed material and avoid the situation of falling caused by the conveyed material being too heavy; The driving member 202 includes a motor, a synchronous chain belt and synchronous gears. The motor drives one of the synchronous gears to rotate. The rotation of the synchronous gear drives all the synchronous gears to rotate through the transmission of the synchronous chain belt, and the synchronous gear drives the conveying roller 201 to rotate. After the conveying roller 201 rotates, it can convey the material, so as to detect the weight of the conveyed material while conveying the material. When it is detected that the conveyed material is too heavy, the addition of the material is reduced.

[0032] As an alternative embodiment, the clamping component includes: Two groups of limiting insertion rods 3, with two limiting insertion rods 3 in a group, and the two groups of limiting insertion rods 3 are symmetrically and movably inserted into the inner part of the cylindrical grooves 301 at both ends of the lifting platform 104; Two first cylinders 302, with two first cylinders 302 in a group, and the two groups of first cylinders 302 are symmetrically installed at both ends of the lifting platform 104 to drive the respective limiting insertion rods 3 to move horizontally; Two anti-falling frames 303, respectively installed at both ends of the platform 1; Two groups of limiting grooves 304, with two limiting grooves 304 in a group, and the two groups of limiting grooves 304 are respectively symmetrically formed on the opposite sides of the two anti-falling frames 303, and the limiting grooves 304 are adapted to the limiting insertion rods 3; Two air flushing mechanisms, respectively installed inside the two anti-falling frames 303, and used to clean the inside of the limiting grooves 304 when the limiting insertion rods 3 are connected; Two falling triggering mechanisms, respectively installed inside the two anti-falling frames 303, and used to identify the fall of the lifting platform 104; After the first cylinder 302 is started, it drives the connected limiting insertion rod 3 to move, so that the limiting insertion rod 3 is inserted into the inside of the limiting groove 304. The air flushing mechanism can be triggered when the limiting insertion rod 3 is connected, so as to impact the inside of the limiting groove 304 through the action of air flow during connection, which is beneficial to removing pollutants such as debris accumulated inside the limiting groove 304, and is beneficial to avoiding the situation that the blocking of the limiting groove 304 affects the insertion; After the limiting insertion rod 3 is connected, it clamps and supports the lifting platform 104. When the lifting platform 104 still has a falling situation, the falling triggering mechanism is started. After the falling triggering mechanism is started, it further supports the lifting platform 104, so that when the lifting platform 104 has a falling situation, it can quickly support and protect the lifting platform 104, which is beneficial to avoiding the situation that the materials conveyed are damaged due to the fall of the lifting platform 104.

[0033] As an alternative embodiment, the clamping component further includes: Four straight rods 305, respectively installed inside the respective limiting grooves 304; Four discs 4, respectively rotatably connected to the ends of the four straight rods 305 through universal balls; Four groups of pressure sensors 401, and the four groups of pressure sensors 401 are respectively installed at the ends of the four straight rods 305 in a circumferential array. When the disc 4 is offset and squeezed, some of the pressure sensors 401 in the same group are not stressed; When the limit insertion rod 3 presses against the disc 4, the diameter of the end of the limit insertion rod 3 decreases, reducing the contact area between the limit insertion rod 3 and the disc 4. When the limit insertion rod 3 is offset, the limit insertion rod 3 presses against the edge of the disc 4, causing the limit insertion rod 3 to be offset after being pressed, so that part of the pressure sensor 401 is not stressed, enabling the offset of the limit insertion rod 3 to be identified, and enabling a warning to be given in a timely manner when the limit insertion rod 3 is offset, to prompt the staff that the lifting platform 104 is offset, so that the staff can check the lifting platform 104 in a timely manner to avoid the situation of continued use and falling after the lifting platform 104 is damaged.

[0034] As an alternative embodiment, the air flushing mechanism includes: Two second pressure sensors, respectively installed on the side walls of the two discs 4 of the same anti-falling frame 303, and when the limit insertion rod 3 is connected, the second pressure sensors are stressed; An air pump 306, installed inside the anti-falling frame 303; A connecting pipe 307, fixed inside the anti-falling frame 303, and the output end of the air pump 306 communicates with the connecting pipe 307; Two output pipes 308, respectively embedded and installed on the inner walls of the two limit slots 304, both two output pipes 308 communicate with the connecting pipe 307, and a plurality of one-way exhaust holes are installed on both two output pipes 308; After the second pressure sensors are stressed, they control the air pump 306 to start. The air pump 306 conveys gas into the inside of the connecting pipe 307. The gas inside the connecting pipe 307 enters the inside of the output pipe 308, and then quickly discharges through the one-way exhaust holes inside the output pipe 308 to form a high-pressure air flow, so as to clean the pollutants inside the limit slot 304 through the action of the high-pressure air flow, which is beneficial to avoiding the situation that the limit slot 304 is blocked and affects the clamping connection.

[0035] As an alternative embodiment, the clamping component further includes: Two groups of support platforms 5, with multiple support platforms 5 as a group, and the two groups of support platforms 5 are respectively movably inserted into a plurality of receiving slots 503 opened on the opposite sides of the two anti-falling frames 303; Two groups of second cylinders 501, arranged corresponding to the support platforms 5, respectively installed inside the corresponding anti-falling frames 303, and the second cylinders 501 are used to push the corresponding support platforms 5 to extend out of the receiving slots 503; A plurality of pushing plates 502, respectively fixed to the ends of the expansion rods of the respective second cylinders 501, and all the pushing plates 502 are respectively slidably connected to the inside of the annular chutes on the respective support platforms 5 through sliding contacts; When the lifting platform 104 falls, the fall trigger mechanism is triggered, thereby controlling the second cylinder 501 to start. The second cylinder 501 pushes the push plate 502, and through the push plate 502, the support platform 5 is pushed, so that the support platform 5 extends completely. The extended support platform 5 can catch the falling lifting platform 104, which is beneficial to avoid large-distance falls of the lifting platform 104. In the case of small-distance falls, it can reduce the damage to the conveyed materials.

After the support platform 5 rotates, it lifts the object supported on the top; After the motor 6 starts, it can drive the cross insertion rod 601 to rotate, and the cross insertion rod 601 drives the support platform 5 to rotate, so that the part with an increased bottom radius after rotation is rotated to the top after rotation, thereby lifting the lifting platform 104 through the rotation effect, so that the falling lifting platform 104 can be re-aligned with the platform 1 under the lifting effect, so that the lifting platform 104 can normally support the weighing and conveying component in a short time, so as to realize normal conveying within a short time, so that the materials to be continuously conveyed can be completed through emergency conveying within a short time, which is beneficial to reducing the adverse impact of the fall on the conveying.

[0037] As an alternative embodiment, the clamping component further includes: A plurality of buffer plates 7 are respectively installed on the tops of the respective support platforms 5; A plurality of elastic support rods 701 are respectively fixed inside the respective support platforms 5, and the tops of all the elastic support rods 701 are respectively connected to the respective buffer plates 7; A plurality of relief grooves are respectively opened on the tops of the respective support platforms 5, and the relief grooves are adapted to the buffer plates 7; When the lifting platform 104 falls, during the falling process, it impacts and presses the buffer plate 7. The buffer plate 7 is elastically supported by the elastic support rods 701. Through the arrangement of the plurality of elastic support rods 701, part of the impact force of the fall is buffered, which is beneficial to reducing the impact generated by the fall and is beneficial to reducing equipment damage and material damage caused by the fall.

[0038] As an alternative embodiment, the fall trigger mechanism includes: A gear 801 rotatably installed inside the anti-fall frame 303, with the gear 801 sleeved on the outer circle of one of the straight rods 305; A first spring 802 fixed between the straight rod 305 corresponding to the gear 801 and the anti-fall frame 303, and the straight rod 305 and the anti-fall frame 303 are in sliding plug-in connection; A thread groove 803 is opened on the surface of the straight rod 305 corresponding to the gear 801, and the thread groove 803 is adapted to the sliding contact on the inner wall of the gear 801; A threaded rod 805 is rotatably installed inside the anti-fall frame 303; A gear set 804 is installed inside the anti-fall frame 303, and after the gear 801 rotates, it drives the threaded rod 805 to rotate through the gear set 804; A threaded sleeve 806 is threadedly sleeved on the outer circle of the threaded rod 805 and is slidably connected to the anti-fall frame 303, and a pressing head is fixed at the bottom of the threaded sleeve 806; A plurality of trigger buttons 807 are linearly arrayed and installed inside the anti-fall frame 303, and the pressing head is used to press the trigger buttons 807; Two pressing platforms 808 are respectively vertically slidably installed at the bottom of the two limiting grooves 304; Two second springs 809 are fixed between the pressing platform 808 and the anti-fall frame 303, and a third pressure sensor is fixed at the bottom of the pressing platform 808; When the limiting plugging rod 3 moves, it pushes the straight rod 305 to move. After the straight rod 305 moves, it drives the thread groove 803 to move, so as to drive the gear 801 to rotate through the adaptation of the thread groove 803 and the sliding contact on the inner wall of the gear 801. After the gear 801 rotates, it drives the threaded rod 805 to rotate through the gear set 804. After the threaded rod 805 rotates, it drives the threaded sleeve 806 to move, and the threaded sleeve 806 drives the pressing head to move, so as to sequentially squeeze the trigger buttons 807. After the limiting plugging rod 3 is completely plugged, the pressing head passes through all the trigger buttons 807. At this time, if the lifting platform 104 falls, after the limiting plugging rod 3 is damaged, it disengages from the straight rod 305, so that the straight rod 305 resets under the elastic action of the first spring 802, thereby driving the pressing head to reset and move. At this time, due to the fall of the lifting platform 104, the damaged limiting plugging rod 3 squeezes the pressing platform 808, so that the third pressure sensor is pressed. After the third pressure sensor is pressed, when the pressing head sequentially presses the trigger buttons 807, it can sequentially trigger the second cylinder 501 and the motor 6 and alarm, so that the support platform 5 can sequentially extend and rotate to support and lift the lifting platform 104, so as to provide emergency anti-fall protection for the lifting platform 104.

[0039] As Figure 1A control method for an anti-falling component of a combined conveying operation platform shown, the control method comprising the following steps: The control unit obtains the falling information from the clamping component; The control unit generates protection control information according to the falling information, and the protection control information is used to control the clamping component to start emergency support protection; The control unit sends the protection control information to the clamping component; The control unit obtains the weight information M1 from the weighing and conveying component; The control unit obtains the weight threshold information M0 from the user terminal connected to the control unit, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n; The control unit substitutes the weight information M1, the weight threshold information M0, the constant weight M2, and the safety interval coefficient n into the judgment formula M1 ≤ M2 + M0(1 - n). If the judgment formula is met, the control unit generates safety conveying control information, and the safety conveying control information is used to prompt the staff that safe emergency conveying can be carried out in the current state. If the judgment formula is not met, the control unit generates emergency pause control information, and the emergency pause control information is used to prompt the staff that an emergency pause is required immediately in the current state; The control unit sends the safety conveying control information or the emergency pause control information to the user terminal; When the lifting table 104 falls, the clamping component monitors the fall and generates fall information, and then sends the fall information to the control unit, so that the control unit obtains the fall information from the clamping component. The control unit generates protection control information according to the fall information and sends the protection control information to the clamping component to control the clamping component to start emergency support protection, so that the clamping component urgently supports and lifts the falling lifting table 104 to avoid the situation of the large-distance fall of the lifting table 104. After the lifting of the lifting table 104 is completed, the weighing and conveying component monitors the material weight to obtain the weight information M1, and then sends the weight information M1 to the control unit, so that the control unit obtains the weight information M1 from the weighing and conveying component. The staff can input the weight threshold information M0, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n through the user terminal. The weight threshold information M0 is the maximum weight threshold for conveying, which is set by the staff according to different equipment. The constant weight M2 is the weight of the weighing and conveying component itself and is a fixed value. The safety interval coefficient n is the weight ratio left between the maximum weight conveyed after a fall occurs and the weight threshold information M0, so that the control unit can obtain the weight threshold information M0, the constant weight M2 of the weighing and conveying component, and the safety interval coefficient n from the user terminal. Subsequently, the control unit substitutes the above data into the judgment formula M1 ≤ M2 + M0(1 - n). If the judgment formula is met, the control unit generates safety conveying control information and sends the safety conveying control information to the user terminal. The safety conveying control information is used to prompt the staff that safe emergency conveying can be carried out in the current state, so that when there is material that needs to be conveyed urgently, the staff does not temporarily turn off the equipment, but urgently conveys the material within the specified time range and turns off the equipment for maintenance after the conveying is completed. If the judgment formula is not met, the control unit generates emergency pause control information and sends the emergency pause control information to the user terminal. The emergency pause control information is used to prompt the staff that an emergency pause needs to be carried out immediately in the current state, so that when the staff receives the emergency pause control information, they immediately stop the equipment for maintenance because the weight of the material currently conveyed on the weighing and conveying component exceeds the safety value, and further fall may occur if the conveying continues.

[0040] Working principle of the present invention: The lifting frame 103 can drive the lifting platform 104 to move vertically. The lifting frame 103 is any lifting frame commonly used in the prior art. After the lifting platform 104 moves upward, it is flush with the top of the platform 1. The weighing and conveying assembly can convey the materials and weigh the conveyed materials during the conveying process, which is beneficial to avoid the risk that the conveyed materials are too heavy, resulting in the extrusion of the lifting platform 104 during the conveying process and the risk of the lifting platform 104 falling. When the lifting platform 104 is lifted to the highest point and is in the position for conveying the materials, the clamping component can clamp the position of the lifting platform 104, which is beneficial to reduce the risk of the lifting platform 104 falling. And when the lifting platform 104 still has the risk of falling, it can emergently support and protect the lifting platform 104 to avoid the continuous fall of the lifting platform 104, which is beneficial to realize the anti-fall protection of the lifting platform 104, so that the lifting platform 104 can be protected when there is a fall or a risk of falling, which is beneficial to avoid the situation that the lifting platform 104 falls completely downward and causes damage or the materials conveyed above are damaged.
