Description

Technical Field

[0001] The present invention relates to the technical field of building elevators, and in particular to an automatic elevator device. Background Art

[0002] A lift is a type of lifting machinery used to transport people or objects vertically. It's particularly useful for vertical transportation at construction sites. Lifts are often equipped with various flat conveying devices, connecting conveyor lines at different heights. They're typically hydraulically driven, hence the name hydraulic lift. Besides transporting cargo at varying heights, they're also widely used for high-altitude installation and maintenance operations.

[0003] At present, there are some existing technologies that can, for example, patent publication number CN219362930U, whose main technical means is to drive the driving roller to rotate by the main reel, and the driving roller drives the steel cable to rotate, so that the first cargo compartment rises while the second cargo compartment descends. When the first cargo compartment reaches the loading floor, the movable connection on the second cargo compartment opens, and the second reel reels or releases the second steel cable, so that the second cargo compartment reaches the unloading floor. After reaching the unloading floor, the movable connection on the second cargo compartment is locked and connected with the steel cable again. At this time, the first cargo compartment and the second cargo compartment can be lifted and lowered relative to each other at the same time, and the first cargo compartment and the second cargo compartment reach the loading floor and the unloading floor at the same time, realizing simultaneous loading and unloading. After analysis, the disadvantage of this technical solution is that when the two cargo boxes are driven by the steel cable at the same time, the bearing pressure of the steel cable is large and it is very easy to break. There is no auxiliary device for the steel cable in the prior art. After breaking, the cargo box will fall and cause damage to the lifted building materials. Based on this, the present invention provides an automatic lifting device with a simple and ingenious structure that can automatically protect the steel cable. Summary of the Invention

A movable rod is slidably installed in the box body, and a hook is installed at the end of the movable rod close to the support rod, and the movable rod is connected to the transmission assembly; when the cargo box drops rapidly, the transmission assembly starts and drives the movable rod to instantly extend out of the box body, and the hook moves to the other side of the support rod and hangs on the support rod.

[0006] As a further solution of the present invention: the transmission assembly includes: A speed meter, mounted on the top of the cargo box and positioned toward the support rod; and The sliding plate is slidably installed in the box body and is connected to the fixed plate by a spring. The fixed plate is fixed to the box body. The sliding plate is connected to an electric telescopic block, and the electric telescopic block is engaged with a slot provided on the inner wall of the box body. The electric telescopic block is connected to a speedometer; when the electric telescopic block is in an extended state, it extends out of the sliding plate and is engaged in the slot, and the spring is in a compressed state at this time; when the speedometer detects that the relative movement speed of the support rod is greater than a threshold value, it determines that the cargo box is in a rapid descending state, then the electric telescopic block contracts and slides away from the slot, and the elastic force of the spring drives the movable rod to extend instantaneously.

[0007] As a further solution of the present invention: the sliding plate and the fixed plate are both made of magnetic materials, and the sliding plate and the fixed plate magnetically repel each other.

[0008] As a further solution of the present invention: there are two hooks, and the two hooks are movably installed on the top and bottom surfaces of the movable rod respectively; when the movable rod is instantly extended, the hook hits the support rod and moves toward the movable rod until the hook slides off the support rod.

[0009] As a further solution of the present invention: a trigger assembly is installed on the movable rod, a baffle is slidably installed on the movable rod, and the trigger assembly is connected to the baffle; when the hook hits the support rod, the baffle is located between the support rods on both sides; when the hook moves toward the direction close to the movable rod, the trigger assembly is activated and drives the baffle to descend.

[0010] As a further solution of the present invention: the trigger component includes: A displacement sensor is mounted on the movable rod and arranged toward the hook; an elastic telescopic block, one end of which is fixed to the movable rod and the other end of which is connected to the hook; and The output source has a fixed end installed at the bottom of the movable rod and an output end connected to the baffle, and the output source is connected to the displacement sensor.

[0011] As a further scheme of the present application: the bottom of the box is rotationally connected with the same end of the first and second columns, the other end of the first column is fixed to the top of the box, and the other end of the second column is connected with the output end of the telescopic rod, and the fixed end of the telescopic rod is mounted to the top of the box.

(2) In the present application, during the process of the instant extension of the movable rod, when the hook hits the support rod, the hook will move towards the movable rod, at this time, the elastic expansion block is contracted until the hook slides over the support rod; when the hook moves towards the movable rod, the displacement sensor detects the translation of the hook, and then the output source drives the baffle to descend, which can assist the hook to avoid the problem that the box descends before the hook moves between the two rows of support rods, so that the hook cannot be hung on the support rod to stop the box. (3) In the present application, after the hook is hung on the support rod, the box will continue to descend for a distance, then the telescopic rod is extended, the first and second columns are relatively rotated with the box, the box is rotated until the telescopic rod is extended to the longest state, and during the process, the hook rotates on the support rod, which can delay the stopping process of the box and avoid the problem that the instantaneous stop of the box causes impact force to damage the building materials in the box.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figures 1-4 As shown, the present invention is an automatic elevator device, comprising: A mounting frame 1 is provided with two driving sources 2, which respectively drive two rollers 3 to rotate. The two rollers 3 are rotatably mounted on the mounting frame 1, and two steel cables 4 are mounted on the two rollers 3. Cargo box 5, two of the cargo boxes 5 are fixedly connected to both sides of the steel cable 4, and a guide wheel group 7 is fixed on the surface of the cargo box 5 close to the steel cable 4. The guide wheel group 7 is slidably matched with the guide rail 8, and the guide rail 8 is fixed to the mounting frame 1; A bracket 9 is fixed to the inner side of the guide rail 8, and a plurality of support rods 10 are horizontally arranged at equal intervals on both sides of the bracket 9, and the bracket 9 is located between the two cargo boxes 5; and The box body 11 is fixedly installed on the top of the cargo box 5, and the surface of the box body 11 close to the support rod 10 is open. A movable rod 12 is slidably installed in the box body 11, and a hook 13 is installed at the end of the movable rod 12 close to the support rod 10. The movable rod 12 is connected to the transmission assembly 14; when the cargo box 5 drops rapidly, the transmission assembly 14 starts and drives the movable rod 12 to instantly extend out of the box body 11, and the hook 13 moves to the other side of the support rod 10 and hangs on the support rod 10.

[0019] In one case of this embodiment, the driving source 2 can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the roller 3 rotate, this embodiment does not make specific limitations here; the two ends of the steel cable 4 are respectively mounted on the roller 3; the number of the guide wheel group 7 is at least one, and the guide wheel group 7 includes a wheel frame and a guide wheel, the guide wheel is in contact with the guide rail 8, and the guide rail 8 slides with the wheel frame; each of the cargo boxes 5 is provided with two symmetrically arranged boxes 11, and the hooks 13 on the two cargo boxes 5 are symmetrically arranged, and two rows of support rods 10 are respectively provided on both sides of the bracket 9, and the two rows of support rods 10 are located between the hooks 13 on the two cargo boxes 5; at least one connecting block 6 is fixed on the cargo box 5, and the connecting block 6 is fixedly connected to the steel cable 4.

[0020] When this embodiment is actually used, in the initial state, the movable rod 12 is located in the box body 11, and there is a gap between the hook 13 and the support rod 10; when the two driving sources 2 drive the two rollers 3 to rotate, the steel cable 4 rotates synchronously and drives the two cargo boxes 5 to rise and fall; when the cargo box 5 drops rapidly, the transmission assembly 14 starts and drives the movable rod 12 to instantly extend out of the box body 11, and the hook 13 moves to between the two rows of support rods 10. As the cargo box 5 continues to drop, the hook 13 will be hung on the support rod 10 to prevent the cargo box 5 from continuing to drop and being damaged. After the steel cable 4 breaks due to the large weight pressure of the two cargo boxes 5, it can assist the steel cable 4 to stop the cargo box 5 to prevent it from dropping rapidly and causing the building materials being lifted and transported therein to be damaged.

[0021] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the transmission assembly 14 includes: A speed meter 1401 is mounted on the top of the cargo box 5 and arranged toward the support rod 10; and The sliding plate 1405 is slidably installed in the box body 11, and is connected to the fixed plate 1406 by a spring 1404. The fixed plate 1406 is fixed to the box body 11. The sliding plate 1405 is connected to the electric telescopic block 1402, and the electric telescopic block 1402 is engaged with the slot 1403 provided on the inner wall of the box body 11. The electric telescopic block 1402 is connected to the speedometer 1401; when the electric telescopic block 1402 is in an extended state, it extends out of the sliding plate 1405 and is engaged in the slot 1403. At this time, the spring 1404 is in a compressed state; when the speedometer 1401 detects that the relative movement speed of the support rod 10 is greater than the threshold value, it determines that the cargo box 5 is in a rapidly descending state, then the electric telescopic block 1402 contracts and slides away from the slot 1403, and the elastic force of the spring 1404 drives the movable rod 12 to extend instantaneously.

[0022] In one case of this embodiment, the speedometer 1401 and the electric telescopic block 1402 are both connected to an external controller. The speedometer 1401, the electric telescopic block 1402 and the external controller are all existing technologies, and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0023] When this embodiment is actually used, in the initial state, the electric telescopic block 1402 is in the extended state. At this time, the output end of the electric telescopic block 1402 extends out of the sliding plate 1405 and is locked in the slot 1403, so that the sliding plate 1405 can be stationary in the box body 11; when the cargo box 5 is raised or lowered, the support rod 10 will move relative to the cargo box 5, and the speed meter 1401 can monitor the relative movement speed of the support rod 10. When the relative movement speed of the support rod 10 is greater than the threshold, the device determines that the cargo box 5 is in a rapid descending state, and the electric telescopic block 1402 contracts and slides out of the slot 1403. The elastic force of the spring 1404 to restore the deformation drives the movable rod 12 to extend instantaneously and insert it between the two adjacent support rods 10. After the hook 13 slides over the support rod 10, it is located between the two rows of support rods 10. Then the cargo box 5 continues to descend, allowing the hook 13 to hang on the support rod 10.

[0024] like Figure 4-Figure 5 As shown, as a preferred embodiment of the present invention, the sliding plate 1405 and the fixed plate 1406 are both made of magnetic materials, and the sliding plate 1405 and the fixed plate 1406 magnetically repel each other.

[0025] During actual application of this embodiment, during the process in which the elastic force of the spring 1404 restoring its deformation drives the movable rod 12 to extend instantaneously, the magnetic repulsion between the sliding plate 1405 and the fixed plate 1406 assists the instantaneous extension of the movable rod 12, which can avoid the problem of the speed of the movable rod 12 being reduced due to the decrease in the elastic force of the spring 1404 after long-term use, thereby ensuring that the movable rod 12 can be extended instantaneously and the acceleration hook 13 is hung on the support rod 10, thereby quickly stopping the cargo box 5.

[0026] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the number of the hooks 13 is two, and the two hooks 13 are movably installed on the top and bottom surfaces of the movable rod 12 respectively; when the movable rod 12 is instantly extended, the hook 13 hits the support rod 10, and it will move toward the direction close to the movable rod 12 until the hook 13 slides off the support rod 10.

[0027] In one case of this embodiment, a trigger assembly 15 is installed on the movable rod 12, a baffle 16 is slidably installed on the movable rod 12, and the trigger assembly 15 is connected to the baffle 16; when the hook 13 hits the support rod 10, the baffle 16 is located between the support rods 10 on both sides; when the hook 13 moves toward the direction close to the movable rod 12, the trigger assembly 15 is activated and drives the baffle 16 to descend.

[0028] Wherein, the trigger component 15 includes: A displacement sensor 1501 is mounted on the movable rod 12 and arranged toward the hook 13; An elastic telescopic block 1502, one end of which is fixed to the movable rod 12 and the other end of which is connected to the hook 13; and The output source 1503 has a fixed end mounted on the bottom of the movable rod 12 and an output end connected to the baffle 16 . The output source 1503 is connected to the displacement sensor 1501 .

[0029] It should be noted that the displacement sensor 1501 and the output source 1503 are both connected to an external controller. The displacement sensor 1501 and the output source 1503 are both existing technologies, and this application does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application; the output source 1503 can be a hydraulic cylinder, a pneumatic cylinder and other components, and can also be other mechanisms that can achieve linear motion. This embodiment does not make specific limitations here.

[0030] During actual application of this embodiment, when the movable rod 12 is instantaneously extended, when the hook 13 hits the support rod 10, the hook 13 will move toward the movable rod 12. At this time, the elastic telescopic block 1502 contracts until the hook 13 slides over the support rod 10; when the hook 13 moves toward the movable rod 12, the displacement sensor 1501 detects the translation of the hook 13, and the output source 1503 drives the baffle 16 to descend, which can assist the hook 13 and avoid the problem that the hook 13 fails to move to the two rows of support rods 10 in time and the cargo box 5 descends, resulting in the hook 13 failing to hang on the support rod 10 and unable to stop the cargo box 5.

[0031] like Figure 3-Figure 5 As shown, as a preferred embodiment of the present invention, the bottom of the box body 11 is rotatably connected to the same end of the first column 17 and the second column 18, the other end of the first column 17 is fixed to the top of the cargo box 5, and the other end of the second column 18 is connected to the output end of the telescopic rod 19, and the fixed end of the telescopic rod 19 is installed on the top of the cargo box 5.

[0032] In one case of this embodiment, a counterweight 20 is fixed to the bottom of the box body 11; when the telescopic rod 19 is in a free state, the box body 11 is arranged horizontally.

[0033] In actual application of this embodiment, after the hook 13 is hung on the support rod 10, the cargo box 5 will continue to descend for a distance, then the telescopic rod 19 will extend, the first column 17 and the second column 18 will rotate relative to the box body 11, and the box body 11 will rotate until the telescopic rod 19 is extended to its longest state. During this process, the hook 13 rotates on the support rod 10. This setting can delay the stopping process of the cargo box 5 and avoid the problem that the impact force caused by the instantaneous stop of the cargo box 5 causes damage to the building materials inside it.

[0034] Working principle of the present invention: The above embodiment of the present invention provides an automatic lifting device. When the cargo box 5 drops rapidly, the transmission assembly 14 starts and drives the movable rod 12 to instantly extend out of the box body 11, and the hook 13 moves to between the two rows of support rods 10. As the cargo box 5 continues to drop, the hook 13 will be hung on the support rod 10 to prevent the cargo box 5 from continuing to drop and being damaged. After the weight pressure of the two cargo boxes 5 is too large and the steel cable 4 breaks, it can assist the steel cable 4 to stop the cargo box 5 and prevent it from dropping rapidly and causing the construction materials lifted and transported therein to be damaged.

[0035] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
