Description

Technical Field

[0001] This invention relates to the field of elevators, and more particularly to an automated industrial material transport elevator with fall protection. Background Technology

[0002] In existing technologies, there are several significant problems when using elevators in conjunction with dump trucks to transport materials from low to high places. On the one hand, during the process of the elevator lifting and lowering the dump truck loaded with materials, the dump truck is prone to shaking due to vibration or inertia from the operation of the equipment. This can cause materials to fall out of the dump truck, affecting transportation efficiency and the site environment, or even lead to serious safety accidents such as the dump truck falling off the elevator. On the other hand, after the elevator transports the dump truck to the high platform, workers often have to place one or even both feet on the lifting components of the elevator to operate it when retrieving or placing the dump truck, due to the limited arm length. This greatly increases the risk of workers falling from heights and poses a serious safety hazard. Summary of the Invention

[0003] In order to overcome the shortcomings of the elevator transporting dump trucks, such as the dump trucks easily shaking and causing materials to fall or even crash, and the fact that workers need to step on the lifting components when retrieving materials from heights, which poses a great safety hazard, this invention provides an automated industrial material transport elevator that prevents falls.

[0004] An automated industrial material transport elevator with fall protection includes an elevator body and a lifting plate; the lifting plate is fixedly connected to the lifting part of the elevator body.

[0005] It also includes a rotating plate, a receiving plate, and a supporting plate; the rotating plate is rotatably connected to one side of the lifting plate; a receiving plate is slidably connected to each of the two slots of the lifting plate; and the receiving plate also slides in the slot of the rotating plate; a supporting plate is fixed to the side of the receiving plate near the lifting part; the wheel and outrigger are supported by the receiving plate, and the wheel is supported and limited by the supporting plate.

[0007] Preferably, it further includes a second drive assembly, which includes an electric push rod and a connecting plate; the electric push rod is rotatably connected to the right side of the lifting plate; the telescopic part of the electric push rod is rotatably connected to the connecting plate; the connecting plate is fixedly connected to the rotating plate.

[0008] Preferably, the rotating plate has a slot adapted to the handle of the dump truck.

[0009] Preferably, the right side of the upper surface of the receiving plate is provided with multiple anti-slip raised strips.

[0010] Preferably, it also includes a pressing plate, a locking block, and a spring; multiple springs are fixedly connected to the side of the upright plate; one end of the spring is fixedly connected to the pressing plate; multiple locking blocks are fixedly connected to the pressing plate, and the locking blocks pass through the upright plate and enter its slot.

[0011] Preferably, a column is fixedly connected to the left side of the lifting plate; the extrusion plate has a first inclined portion on the side near the lifting part; the column is guided to extrude the extrusion plate through the first inclined portion.

[0012] Preferably, the locking block has a telescopic component, which allows the locking block to adaptively abut against the wheel.

[0013] Preferably, it also includes a second electric slider, a fall arrestor, a long connecting column, a short connecting column, and a support plate; the second electric slider is slidably connected to the electric slide rail; the fall arrestor is fixedly connected to the second electric slider; multiple long connecting columns and short connecting columns are connected to the elevator body, and the long connecting columns and short connecting columns are spaced apart; a support plate is fixedly connected to one side of each long connecting column and short connecting column.

[0014] Preferably, the long connecting column, the short connecting column and the elevator body are detachably connected.

[0015] This invention effectively solves the risk of swaying and falling when transporting dump trucks using existing elevators, as well as the safety hazards for workers operating at heights.

[0016] To address the problem of materials falling or even crashing due to vibration or inertial swaying in dump trucks, this invention achieves precise positioning through multiple structural synergies: a trapezoidal slotted abutment plate directly supports and abuts the wheels, its closed side limiting the dump truck's pushing distance, and together with the support plate supporting the outriggers, forming a basic positioning system; a clamping block and spring form an elastic clamping structure, the spring's preload causing the compression plate and clamping block to conform to the wheels, a second inclined section guides the dump truck to be centered, and the telescopic component adapts to the wheel's tilt state, ensuring tight clamping; the column cooperates with the first inclined section, and after the dump truck is positioned, the compression plate further increases the clamping force of the clamping block, rotating the lifting plate to a vertical position; the rotating plate limits the right side of the dump truck, and the cooperation between the rotating plate and the abutment plate improves the stability of the dump truck during lifting and lowering, preventing falls. This multi-layered fixing completely avoids dump truck swaying during transportation, eliminating material falling and crashing accidents.

[0017] To address the issue of workers needing to step on lifting components when retrieving and placing dump trucks from heights, this invention achieves safe operation through two movable structural designs: a rotating plate and a lifting plate are rotatably connected, and in conjunction with a second drive assembly (an electric push rod driving a connecting plate), the plate can rotate to a vertical position during transport, forming a left-right bidirectional limit with the upright plate; during retrieval and placement, it rotates to a horizontal position, forming a continuous plane with the receiving plate; a first drive assembly (an electric slide rail driving a first electric slider and a connecting block) drives the receiving plate to slide within the slots of the rotating plate and the lifting plate, pushing the dump truck to the side closer to the platform. Workers do not need to step on the lifting components; they can complete the retrieval and placement from the platform, completely eliminating the risk of trampling at heights.

[0018] To address the potential risk of the lifting platform falling due to a malfunction in the lifting machine itself, a second electric slider moves the anti-fall plate on the electric slide rail, avoiding the support plate during normal lifting. In the event of a fall, the support plates on the spaced long and short connecting columns can support the anti-fall plate, preventing the lifting platform from falling rapidly, thus adding multiple safety redundancies to the equipment operation.

[0029] A fall-prevention automated industrial material handling elevator, such as Figures 1-8 As shown, it includes a lift body 1 and a lift plate 2; the lift plate 2 is fixedly connected to the lifting part 1a of the lift body 1.

[0030] It also includes a rotating plate 3, a receiving plate 4, and abutting plate 5; the rotating plate 3 is rotatably connected to one side of the lifting plate 2; a receiving plate 4 is slidably connected to each of the two slots of the lifting plate 2; and the receiving plate 4 also slides within the slots of the rotating plate 3; the abutting plate 5 is fixedly connected to the side of the receiving plate 4 near the lifting part 1a; the wheel 01a and the outrigger 01b are supported by the receiving plate 4, and the wheel 01a is abutted and limited by the abutting plate 5, such as... Figure 5 As shown, the abutment plate 5 is trapezoidal in shape and has a slot.

[0031] It also includes a first drive assembly 6, which includes an electric slide rail 61, a first electric slider 62, and a connecting block 63; the electric slide rail 61 is installed on the lower side of the lifting plate 2; the first electric slider 62 is slidably connected to the electric slide rail 61; the connecting block 63 is fixedly connected to the first electric slider 62; the connecting block 63 is fixedly connected to the bottom of the receiving plate 4, and the first electric slider 62 slides on the electric slide rail 61, driving the receiving plate 4 to move to the left or right through the connecting block 63.

[0032] It also includes a second drive assembly 7, which includes an electric push rod 71 and a connecting plate 72; the electric push rod 71 is rotatably connected to the right side of the lifting plate 2; the telescopic part of the electric push rod 71 is rotatably connected to the connecting plate 72; the connecting plate 72 is fixedly connected to the rotating plate 3, and the rotating plate 3 is driven to rotate relative to the lifting plate 2 by the telescopic part of the electric push rod 71.

[0033] The rotating plate 3 has a slot adapted to the handle of the dump truck 01, which is used to limit the position of the handle of the dump truck 01.

[0034] Multiple anti-slip ridges are provided on the right side of the upper surface of the receiving plate 4.

[0035] It also includes a pressing plate 101, a locking block 102 and a spring 103; multiple springs 103 are fixedly connected to the side of the upright plate 5; one end of the spring 103 is fixedly connected to the pressing plate 101; multiple locking blocks 102 are fixedly connected to the pressing plate 101, and the locking blocks 102 pass through the upright plate 5 and enter its slot.

[0036] The card block 102 has a second inclined portion 102a.

[0037] A column 104 is fixedly connected to the left side of the lifting plate 2; the pressing plate 101 has a first inclined part 101a on the side near the lifting part 1a; the column 104 is guided to press the pressing plate 101 through the first inclined part 101a.

[0038] The locking block 102 has a telescopic component 102b, which allows the locking block 102 to adaptively abut against the wheel 01a.

[0039] It also includes a second electric slider 201, a fall arrestor 202, a long connecting column 203, a short connecting column 204, and a support plate 205; the second electric slider 201 is slidably connected to the electric slide rail 61; the fall arrestor 202 is fixedly connected to the second electric slider 201; multiple long connecting columns 203 and short connecting columns 204 are connected to the elevator body 1, and the long connecting columns 203 and short connecting columns 204 are distributed at intervals; a support plate 205 is fixedly connected to one side of each of the long connecting columns 203 and short connecting columns 204.

[0040] The long connecting column 203 and the short connecting column 204 are detachably connected to the lifting platform body 1, which facilitates adjustment according to the height of the platform.

[0041] In existing technologies, dump trucks are often used to load and move materials when transporting them from low to high places. The dump truck loaded with materials is placed in an elevator, which moves the dump truck upwards to transport the materials. However, there are problems. When the elevator moves the dump truck up and down, the dump truck will shake. At best, the materials will fall off, and at worst, the dump truck will fall downwards. In addition, when workers push the dump truck out from the high platform, they need to step on the lifting parts of the elevator, which poses a great safety hazard.

[0042] When using this invention, first control the lifting unit 1a to move down to the ground, such as... Figures 2-4 As shown, at this time the rotating plate 3 is in a horizontal state, and the first electric slider 62 is controlled to move to the right on the electric slide rail 61. The first electric slider 62 drives the receiving plate 4 and the abutting plate 5 to move to the right through the connecting block 63. At this time, the right side of the receiving plate 4 enters the slot of the rotating plate 3.

[0043] Then the worker pushes the dump truck 01 loaded with materials onto the plane formed by the rotating plate 3 and the receiving plate 4, and then pushes the wheels 01a into the abutment plate 5, with the wheels 01a located in the slots of the abutment plate 5, and places the outriggers 01b on the anti-slip protrusions of the receiving plate 4; further, as Figure 2 As shown, when the wheel 01a is pushed into the abutting plate 5, the left side of the abutting plate 5 is closed to allow the wheel 01a to abut against it, so that the worker can easily control the pushing distance of the dump truck 01; at the same time, when the wheel 01a enters the abutting plate 5, it contacts the second inclined part 102a. Both abutting plates 5 have a locking block 102 on one side to guide the worker to push the dump truck 01 to the center position.

[0044] After wheel 01a enters the abutting plate 5, spring 103 drives the pressing plate 101 and the locking block 102 to move towards wheel 01a. The force of spring 103 causes the locking block 102 to abut against wheel 01a. At the same time, under the combined action of the support leg 01b and the anti-slip convex strip, the active movement of the dump truck 01 is prevented.

[0045] Then, as Figures 1-7 As shown, the first electric slider 62 drives the receiving plate 4 to move to the left and reset via the connecting block 63. The receiving plate 4 drives the abutment plate 5 and the tipper truck 01 to move to the left. When the pressing plate 101 moves to the left and contacts the column 104, the first inclined part 101a guides the column 104 to press the pressing plate 101. Then the pressing plate 101 further drives the locking block 102 towards the wheel 01a, so that the locking block 102 applies an additional force to the wheel 01a, improving the stability of the tipper truck 01 during subsequent lifting and lowering. At the same time, by setting a telescopic component 102b for each locking block 102, it can adapt to the tilt of the wheel 01a, ensuring that the locking block 102 applies a force to the wheel 01a. It should be noted that when the pressing plate 101 moves to the right and separates from the column 104, the locking block 102 does not apply an additional force to the wheel 01a, only the force of the spring 103. At this time, when the worker lifts the outrigger 01b and pulls the tipper truck 01, the force of the spring 103 can be overcome.

[0046] Furthermore, such as Figures 2-4 As shown, the telescopic part of the control electric push rod 71 retracts, thereby driving the connecting plate 72 to drive the rotating plate 3 to rotate relative to the lifting plate 2, rotating the lifting plate 2 to a vertical state; the rotating plate 3 limits the right side of the dump truck 01, and the cooperation between the rotating plate 3 and the abutting upright plate 5 improves the stability of the dump truck 01 during the lifting process and prevents it from falling.

[0047] Furthermore, when the lifting plate 2 moves up to the high platform, the present invention is controlled to present... Figure 2As shown, the rotating plate 3 is horizontal, and the receiving plate 4 moves the tipper truck 01 to the right. In this way, the worker can grab the handle of the tipper truck 01 at the platform and take it away without having to step on the rotating plate 3 because his arms are not long enough, which greatly ensures the safety of the worker working at height.

[0048] Furthermore, to prevent a malfunction of the elevator body 1 from causing the lifting plate 2 to fall rapidly, this invention includes a second electric slider 201, a fall arrestor 202, a long connecting column 203, a short connecting column 204, and a support plate 205; as shown Figure 8 As shown, because the length of the long connecting column 203 is greater than that of the short connecting column 204, and they are spaced apart from each other, when the lifting plate 2 falls rapidly, the anti-fall plate 202 will contact the support plate 205 on the long connecting column 203 or the short connecting column 204 after falling a certain distance, thereby supporting the lifting plate 2 and overcoming the falling problem. When the lifting plate 2 is raised and lowered, the anti-fall plate 202 moves left and right on the electric slide rail 61 via the second electric slider 201 to avoid the support plate 205. In this way, by setting the second electric slider 201, the anti-fall plate 202, the long connecting column 203, the short connecting column 204 and the support plate 205, the normal raising and lowering action of the lifting plate 2 can be maintained. Moreover, when the lifting plate 2 falls, the support plate 205 supports the anti-fall plate 202 to prevent the lifting plate 2 from falling, thus ensuring the safety of operation.

[0049] As can be seen from the above, the present invention effectively solves the risk of shaking and falling when transporting dump trucks by existing elevators and the safety hazards of workers operating at heights;

[0050] To address the issue of materials falling or even crashing due to vibration or inertial swaying of the dump truck 01, this invention achieves precise positioning through a multi-layered structural synergy: the trapezoidal slotted abutment plate 5 directly supports and abuts against the wheel 01a, and its closed side limits the pushing distance of the dump truck 01. Combined with the support plate 4 supporting the outriggers 01b, this forms a basic positioning mechanism; the clamping block 102 and spring 103 form an elastic clamping structure, and the pre-tensioning force of the spring 103 causes the pressing plate 101 and the clamping block 102 to adhere to the wheel 01a; the second inclined part 102a guides the dump truck 01 to be placed in the center; and the telescopic part... Component 102b adapts to the tilting state of wheel 01a to ensure tight clamping; the column 104 cooperates with the first tilting part 101a, and after the tipper truck 01 is positioned, it further increases the clamping force of the clamping block 102 by squeezing the squeezing plate 101, and rotates the lifting plate 2 to a vertical state; the rotating plate 3 limits the right side of the tipper truck 01, and the cooperation between the rotating plate 3 and the abutting plate 5 improves the stability of the tipper truck 01 during the lifting process and prevents it from falling. In this way, multiple fixation is achieved, which completely avoids the tipper truck 01 shaking during transportation and eliminates material falling and falling accidents.

[0051] To address the issue of workers needing to step on the lifting part 1a when retrieving or placing the dump truck 01 from a height, this invention achieves safe operation through two movable structural designs: the rotating plate 3 is rotatably connected to the lifting plate 2, and in conjunction with the second drive assembly 7 (electric push rod 71 driving connecting plate 72), it can rotate to a vertical state during transportation, forming a left-right bidirectional limit with the abutment plate 5; during retrieval or placement, it rotates to a horizontal state, forming a continuous plane with the receiving plate 4; the first drive assembly 6 (electric slide rail 61 driving the first electric slider 62 and connecting block 63) drives the receiving plate 4 to slide within the slots of the rotating plate 3 and the lifting plate 2, which can push the dump truck 01 to the side closer to the platform. Workers do not need to step on the lifting part 1a; they can complete the retrieval or placement at the platform, completely eliminating the risk of being trampled at height.

[0052] To address the potential risk of the lifting platform 2 falling due to a malfunction of the lifting body 1, the second electric slider 201 drives the anti-fall plate 202 to move on the electric slide rail 61. During normal lifting, it can avoid the support plate 205. When a fall occurs, the support plates 205 on the spaced long connecting columns 203 and short connecting columns 204 can support the anti-fall plate 202, preventing the lifting platform 2 from falling rapidly, thus adding multiple safety redundancies to the equipment operation.

[0053] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
