Description

Technical Field

[0001] This utility model relates to the technical field of fall protection design for lifting devices, specifically a fall-triggered lifting platform. Background Technology

[0002] In the field of modern engineering machinery, ensuring the safety of equipment operation is paramount. Preventing accidents caused by rope breakage is a key issue, leading to the development of rope breakage locking protection devices. Ratchet caliper type is a common rope breakage protection technology. The core principle of this type of device utilizes the one-way locking characteristic of a ratchet. A ratchet typically consists of a series of teeth, and the caliper that engages with it allows the rope to pass smoothly through the ratchet during normal operation. However, once the rope breaks, the caliper quickly locks the ratchet, preventing further movement of the equipment and thus providing protection. This type of device is commonly used in elevators, hoists, and similar equipment.

[0003] The ratchet caliper type rope breakage protection solution has the disadvantages of complex structure, high design precision, and low adaptability. For the new type of lifting platform used on piling vessels, how to design a fall-prevention trigger lifting platform with a simpler structure, higher adaptability, and economic rationality is a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to provide a fall-prevention trigger-type lifting platform, which can effectively protect against falls when the lifting rope breaks; at the same time, the fall-prevention trigger-type lifting platform has the characteristics of simple structure and high installation adaptability, which meets its application in offshore lifting platforms.

[0005] A fall-prevention trigger-operated lifting platform includes: a platform support extending vertically and comprising at least two vertical guide rails on both sides, with multiple positioning beams spaced apart between the two vertical guide rails; a mounting frame for positioning and assembling the movable platform, the mounting frame having two vertical support sections on both sides, with guide pulleys on the two vertical support sections for slidably connecting to the two vertical guide rails; a horizontal support section between the two vertical support sections, with a main rope connection point at the center of the horizontal support section, trigger-operated locking structures on both sides of the main rope connection point, and auxiliary rope connection points on the trigger-operated locking structures; and a lifting drive device located at the upper end of the platform support. A main connecting rope extends vertically downwards, with its end connected to the main rope connection point. Secondary connecting ropes extend from both sides of the end of the main connecting rope, with their ends connected to their respective connection points. In the connected state, the secondary connecting ropes exert an upward pulling force on the trigger-locking structures on both sides. When the main connecting rope breaks off from the lifting drive device, the secondary connecting ropes lose their connection to the main connecting rope and thus lose the pulling force, causing the trigger-locking structures on both sides to move towards the positioning beam. The positioning beam engages with the trigger-locking structure, positioning the movable platform against the platform support.

[0006] Furthermore, the trigger-type locking structure includes a locking plate and a locking seat; one end of the locking plate has a latching position, and the other end has a rotating interface; the latching position is located on the lower side of one end of the locking plate; the lower side of the locking seat is connected to the horizontal section of the bracket, and a connecting shaft is provided on the locking seat, the connecting shaft passing through the rotating interface to allow the locking plate to rotate and connect to the locking seat; an elastic connector is connected between the locking seat and the locking plate; in application, the locking plate includes an unlocked state in one rotational position and a locked state in another rotational position; in the unlocked state, the height of one end of the locking plate is higher than that of the locking plate. In a fixed state, the locking plate is positioned at one end of its height. Under the elastic potential energy of the elastic connector, the locking plate tends to rotate downwards around the connecting axis. In the locked state, the locking plate is locked and positioned relative to the locking seat. The auxiliary rope connection position is provided at the upper end of one end of the locking plate. When the main connecting rope is disconnected from the lifting drive device, the auxiliary connecting ropes on both sides lose their connection support from the main connecting rope and lose the lifting force, causing the locking plates on both sides to rotate and move towards the positioning beam. The positioning beam abuts against the locking plate to position the movable platform to the platform support.

[0007] Furthermore, the center of gravity of the locking plate is offset at one end; when the locking plate is connected to the connecting shaft via a rotating interface, the locking plate with its center of gravity offset has a tendency to rotate downwards around the shaft.

[0008] Furthermore, the locking plate is provided with a first latch, the locking seat is provided with a second latch, and the elastic connector includes a spring connector connected between the first latch and the second latch.

[0009] Furthermore, the trigger-type locking structure also includes a movable locking member disposed on the locking seat; the movable locking member includes a locking block disposed near the locking plate, the locking block being connected to an elastic component; when the locking plate is in an unlocked state, the position of the locking plate limits the pushing movement of the locking block, and the elastic component has elastic potential energy; when the locking plate is in a locked state, the position of the locking plate rotates to avoid and release the limitation on the locking block, the elastic potential energy of the elastic component is released, causing the locking block to push out and lock against the locking plate, thereby locking and positioning the locking plate relative to the locking seat.

[0010] Furthermore, in the application of the movable locking member, the pushing direction of the locking block is perpendicular to the flipping and rotating direction of the locking plate; when the locking plate is in the unlocked state, the plate surface of the locking plate on the side of the movable locking member limits the pushing movement of the locking block.

[0011] Furthermore, a limiting block is provided on the lower part of the plate surface of the locking plate near the rotating interface on the side of the plate surface facing the movable locking member; when the locking plate is in the unlocked state, the limiting block on the plate surface limits the pushing movement of the locking block; when the locking plate is in the locked state, the limiting block is below the pushed-out locking block, and the locking block forms a locking stop on the limiting block, thereby locking the position of the locking plate.

[0012] Furthermore, the locking seat is provided with a plurality of through holes on the side corresponding to the connecting shaft; each of the through holes is arranged parallel to the axial direction of the connecting shaft; the movable locking member includes a drive rod that passes through the through hole, one end of the drive rod that is close to the side of the connecting shaft is connected to the locking block, and the drive rod connects the elastic component between the locking block and the locking seat.

[0013] Furthermore, multiple through holes are provided, the locking block is plate-shaped, and each through hole is provided with a drive rod. The ends of the multiple drive rods are connected to one side plate of the locking block, and multiple elastic components are provided between one side plate of the locking block and each drive rod.

[0014] Furthermore, a limiting component is provided at the other end of the drive rod, the outer diameter of which is larger than that of the through hole; a reset hole is provided on the locking seat, and a reset rod is horizontally extended on one side plate of the locking block corresponding to the reset hole, the reset rod passing through the reset hole, and a gripping structure for user gripping is provided at the end of the reset rod away from the locking block.

[0015] The beneficial effects of this utility model are as follows:

[0016] By designing a fall-prevention trigger-type lifting platform for large offshore lifting platform applications, the lifting drive device, in conjunction with a main rope and auxiliary rope, and a mounting frame using guide pulleys and vertical guide rails, provides the overall lifting structure with stable transmission. Furthermore, a trigger-type locking structure is installed between the auxiliary rope and the mounting frame, allowing the lifting platform to extend and engage with the platform support in the event of a breakage of the main rope, thus achieving fall-prevention positioning of the platform.

[0017] The above-mentioned structural setup is characterized by its simplicity and stability. Furthermore, the anti-fall trigger-type lifting platform can be linked with the positioning beam on a conventional offshore platform for positioning and locking, making it reasonable, economical, and scalable for modification and installation.

[0030] To make the technical solution, purpose and advantages of this utility model clearer, the following explanation is given in conjunction with the accompanying drawings and embodiments.

[0031] like Figures 1 to 4 As shown, this utility model discloses a lifting platform with a trigger-locking anti-fall function, which includes a vertically arranged platform support 100. A lifting drive device is mounted on the platform support 100, and a mounting frame 200 is movably mounted on the platform support 100. The movable platform is positioned and mounted on the mounting frame. A lifting rope is provided at the drive end of the lifting drive device to bind the mounting frame 200. Under the drive of the lifting drive device, the mounting frame 200 can drive the movable platform to perform lifting drive movement along the movable guide of the platform support 100.

[0032] The mounting frame 200 and the platform support 100 are equipped with a trigger-type locking structure 1. When the lifting drive device suddenly fails and the movable platform falls, the trigger-type locking structure 1 locks between the platforms, thereby linking the movable platform to the platform support 100 for positioning and stopping.

[0033] Example 1:

[0034] This embodiment describes a specific lifting platform structure.

[0035] The platform support 100 extends vertically and includes at least two vertical guide rails 101 on both sides, with multiple positioning beams 102 arranged at intervals between the two vertical guide rails 101.

[0036] The mounting frame 200 is provided with two vertical support sections 201 on both sides. Guide pulleys 206 are provided on the two vertical support sections 201 to slide and connect to the two vertical guide rails 101 on both sides, so as to meet the sliding and lifting application of the mounting frame 200 in conjunction with the movable platform. The side of the two vertical support sections 201 away from the platform support 100 is provided with a platform mounting position 203 for mounting the movable platform. A support horizontal section 202 is provided between the two vertical support sections 201. A main rope connection position 204 is provided in the center of the support horizontal section 202 for binding the main rope 301 of the lifting rope. The trigger-type locking structure 1 is provided on both sides of the main rope connection position 204, and the auxiliary rope connection position 205 is provided on the trigger-type locking structure 1 for binding the auxiliary rope 302 of the lifting rope.

[0037] The lifting drive device has a connecting main rope 301 extending vertically downward from the upper end of the platform support 100. The end of the connecting main rope 301 is connected to the main rope connection position 204, thus completing the connection of the lifting rope to the lifting drive device and the mounting frame 200.

[0038] At the end of the main rope 301 (near the main rope connection position 204), two connecting auxiliary ropes 302 are extended on both sides, and the ends of the connecting auxiliary ropes 302 on both sides are connected to the auxiliary rope connection positions 205 on both sides. In the state of the lifting rope binding connection to the mounting frame 200, the main rope 301 provides the main lifting force to the mounting frame 200, and the connecting auxiliary ropes 302 on both sides have a certain upward lifting force on the trigger-type locking structure 1 on both sides.

[0039] In application, when the main connecting rope 301 breaks off from the lifting drive device, the movable platform falls due to the main lifting force. At this time, the auxiliary connecting ropes 302 on both sides lose their connection support from the main connecting rope 301 and lose the lifting force, causing the trigger-type locking structures 1 on both sides to move towards the positioning beam 102. The positioning beam 102 engages with the trigger-type locking structure 1 to position the movable platform to the platform support 100, stopping the fall.

[0040] In this embodiment, the trigger-type locking structure 1 is symmetrically arranged on both sides of the main rope connection position 204. During the descent, the trigger-type locking structures 1 on both sides can simultaneously lock the positioning beam 102, ensuring the stability of the moving platform positioning between the platform in the case of a rapid descent.

[0041] Example 2:

[0042] Based on the application of the lifting platform in Embodiment 1, this embodiment further explains the specific settings of a trigger-type locking structure 1.

[0043] The trigger-type locking structure 1 includes:

[0044] Locking plate 2, one end of which has a snap-fit ​​position 21 and the other end is provided with a rotating interface 22.

[0045] A locking seat 3 is provided with a connecting shaft 31, which passes through the rotating interface 22 to rotatably connect the locking plate 2 to the locking seat 3. An elastic connector 32 connects the locking seat 3 and the locking plate 2. In application, the locking plate 2 includes an unlocked state in one rotational position and a locked state in another rotational position. When the locking plate 2 is in the unlocked state, it has a rotational tendency to rotate around the connecting shaft 31 to the locked state under the elastic potential energy of the elastic connector 32.

[0046] A movable locking member 4 is disposed on the locking seat 3; the movable locking member 4 includes a locking block 41 disposed near the locking plate 2, the locking block 41 being connected to an elastic component 42; when the locking plate 2 is in an unlocked state, the position of the locking plate 2 limits the pushing movement of the locking block 41, and the elastic component 42 has elastic potential energy; when the locking plate 2 is in a locked state, the position of the locking plate 2 rotates to avoid and release the limitation on the locking block 41, the elastic potential energy of the elastic component 42 is released, causing the locking block 41 to push out and lock against the locking plate 2, thereby locking the position of the locking plate 2.

[0047] Its application principle is as follows:

[0048] The locking seat 3 is positioned and assembled with the mounting frame 200 to form the trigger-type locking structure 1 integrally mounted on the mounting frame 200. The locking plate 2 is provided with a secondary rope connection position 205 for connecting and binding the secondary rope 302. When the main connecting rope 301 and the secondary connecting rope 302 are connected to the mounting frame 200, the secondary connecting rope 302 exerts an upward pulling force on the locking plate 2, causing the locking plate 2 to be in an unlocked state.

[0049] When the main connecting rope 301 breaks off from the lifting drive device, the auxiliary connecting rope 302 loses its connection support to the main connecting rope 301 and loses its lifting force on the locking plate 2. This causes the locking plate 2 to rotate under the elastic potential energy of the elastic connector 32, reaching a locked state. The locking plate 2 then moves towards the positioning beam 102, causing the latch 21 to engage with the positioning beam 102. In the locked state, the locking plate 2 is restricted by the movable locking member 4, and the locking plate 2 is locked relative to the locking seat 3, maintaining the locked state. The locked plate 2, locked during descent, will then engage with the positioning beam 102, causing the movable platform to stop on the platform support 100. This achieves the application of using a trigger-type locking structure 1 to position the movable platform between platforms during descent.

[0050] As a preferred structural arrangement, in the design of the locking plate 2, the latching position 21 is located on the lower side of one end of the locking plate 2; a first latching position 24 is provided on the plate surface of the locking plate 2 away from the movable locking member 4, and a second latching position 35 is provided on the locking seat 3 corresponding to the flipped lower side position of the locking plate 2; the elastic connecting member 32 includes a spring connecting member connecting the first latching position 24 and the second latching position 35. In the application of the locking plate 2, the height position of one end of the locking plate 2 in the unlocked state is higher than the height position of one end of the locking plate 2 in the locked state, and the locking plate 2 has a tendency to rotate downward around the connecting pivot 31 under the elastic potential energy of the elastic connecting member 32.

[0051] To further ensure that the locking plate 2 can better flip and lean downwards to achieve contact with the platform support 100 when the lifting rope breaks, in this embodiment, the center of gravity of the locking plate 2 is offset at one end. When the locking plate 2 is connected to the connecting shaft 31 through the rotating interface 22, the locking plate 2 with its center of gravity offset has a tendency to rotate downwards around the shaft.

[0052] As a preferred structural configuration, in the design of the movable locking member 4, the pushing direction of the locking block 41 is perpendicular to the flipping and rotating direction of the locking plate 2; when the locking plate 2 is in the unlocked state, the plate surface of the locking plate 2 on the side of the movable locking member 4 limits the pushing activity of the locking block 41.

[0053] Specifically, a limiting block 23 is provided on the lower part of the plate surface of the locking plate 2 near the rotating interface 22 on the side of the plate surface facing the movable locking member 4. When the locking plate 2 is in the unlocked state, the limiting block 23 on the plate surface limits the pushing movement of the locking block 41. When the locking plate 2 is in the locked state, the limiting block 23 is below the pushed-out locking block 41, and the locking block 41 forms a locking limit on the limiting block 23, thereby locking the position of the locking plate 2.

[0054] The locking seat 3 has multiple through holes 33 on the side corresponding to the connecting shaft 31; each through hole 33 is arranged parallel to the axial direction of the connecting shaft 31; the movable locking member 4 includes a drive rod 43 passing through the through hole 33, one end of the drive rod 43 near the connecting shaft 31 is connected to the locking block 41, the locking block 41 is plate-shaped, each through hole 33 has a drive rod 43 passing through it, the ends of the multiple drive rods 43 are connected to one side plate of the locking block 41, and the drive rod 43 connects the elastic component 42 between the locking block 41 and the locking seat 3; the multiple elastic components 42 are disposed between one side plate of the locking block 41 and each drive rod 43.

[0055] Example 3:

[0056] To meet the application requirements of the reusable trigger-type locking structure 1, in the structural application of the movable locking member 4 in the above embodiment 2, a limiting component 44 is provided at the other end of the drive rod 43. The outer diameter of the limiting component 44 is larger than that of the through hole 33. This prevents the drive rod 43 from passing through the locking seat 3 towards the locking plate 2 during application, thus avoiding structural separation. Furthermore, a reset hole 34 is provided on the locking seat 3, and a reset rod 45 extends horizontally on one side of the locking block 41 corresponding to the reset hole 34. The reset rod 45 passes through the reset hole 34, and a gripping structure 46 for user gripping is provided at the end of the reset rod 45 away from the locking block 41.

[0057] When resetting the lifting platform, first, the new connecting main rope 301 is re-attached to the lifting drive device in the main rope connection position 204. Then, the locking block 41, which is used to drive the reset rod 45 by holding the gripping structure 46, is reset to the side away from the locking plate 2, so that the elastic component 42 regains its elastic potential energy. The reset locking block 41 releases the locking restriction on the locking plate 2, so the user can flip the locking plate 2 fastened to the platform bracket 100 to release the fastening, so that the locking plate 2 is in an unlocked state. Then, the new connecting auxiliary rope 302 is attached, thus completing the reset application of the trigger-type locking structure 1 in the lifting platform.

[0058] The above description is only a preferred embodiment of the present utility model. For those skilled in the art, modifications can still be made to the embodiments without departing from the implementation principle of the present utility model, and the corresponding modifications should also be considered within the protection scope of the present utility model.
