Description

Technical Field

[0001] The present invention relates to the technical field of hoisting tools, and particularly to a hoisting tool for a lifting machine with planar deviation correction and elastic buffer fixation. Background Art

[0002] In various fields such as industrial production, construction, and logistics transportation, the hoisting operation is an indispensable and important link. With the rapid development of the economy and the continuous expansion of the scale of engineering projects, higher requirements are put forward for the safety and efficiency of hoisting operations. However, many problems have emerged in the actual application of common hoisting equipment on the market.

[0003] When traditional hoisting devices hoist an object, it is often difficult to accurately align the center of gravity of the hoisted object with the vertical hoisting direction of the hoisting cable. When there is a deviation between the placement position of the hoisted object and the vertical hoisting direction of the hoisting cable, after the hoisted object leaves the ground, it will correct itself towards the vertical hoisting direction along with the hoisting cable. During this correction process, the hoisted object is extremely likely to swing significantly. Especially in crowded areas such as construction sites or industrial production workshops, the swinging hoisted object is very likely to hit the staff on the ground, thus triggering serious safety accidents and posing a great threat to the lives of personnel and the production and operation of enterprises.

[0004] In addition, there are obvious defects in the fixing method of existing hoisting equipment for hoisted objects. Most hoisting equipment uses simple hook or rope fixing methods, which may have a certain applicability for objects with regular shapes and flat surfaces, but it is difficult to achieve firm fixation for objects with irregular shapes. When hoisting an object with an irregular shape, the traditional fixing method is prone to loosening, slipping, etc., which will not only affect the smooth progress of the hoisting operation, but may also cause the hoisted object to fall, resulting in equipment damage and casualties. Moreover, the traditional fixing method lacks an effective buffering mechanism, and during the hoisting process, the vibration and shaking suffered by the hoisted object cannot be effectively alleviated, which further increases the risk of the hoisting operation. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a hoisting tool for a lifting machine with planar deviation correction and elastic buffer fixation, which effectively solves the problems that the hoisted object will swing during the process of correcting itself towards the vertical hoisting direction along with the hoisting cable after leaving the ground, is extremely likely to hit the staff on the ground, causing safety accidents, and has poor applicability in the prior art.

A first upper support rod and a second upper support rod are symmetrically arranged at the two ends of the second cover plate. The first upper support rod and the first lower support rod are parallel to each other and are both rotatably arranged on a third cover plate. The second upper support rod and the second lower support rod are parallel to each other and are both rotatably arranged on another symmetrically arranged third cover plate.

[0010] Preferably, a support plate is fixedly arranged at the lower end of the third cover plate. A rotating plate is positioned and rotatably arranged on the inner side surface of the support plate. A plurality of air pressure cylinders are evenly arranged on the rotating plate. The air pressure cylinders are communicated with each other through a communicating pipe. An air pressure block is slidably arranged inside the air pressure cylinder. A sealing rubber pad for sealing and compressing the air inside the air pressure cylinder is arranged at the inner end of the air pressure block. The outer ends of the air pressure blocks are all fixedly arranged on the rubber pad.

[0011] Preferably, the vertical hanging assembly further includes a sliding hanging plate disposed between the first lower support rod and the second lower support rod. Both ends of the sliding hanging plate are respectively fixedly connected with side frame rods. Upper ends of the side frame rods at both ends of the sliding hanging plate are respectively provided with pin columns slidably connected with inner walls of the first lower support rod and the second lower support rod.

[0012] Preferably, a worm is rotatably connected to the support plate. The worm meshes with a worm gear rotatably connected to the support plate. The worm gear is coaxially and fixedly connected with the rotating plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By providing a planar adjustment structure, the second cover plate moves in a plane, and the second cover plate is adjusted to move directly above the lifted item. Since the lifting direction of the center of gravity of the second cover plate is vertically parallel to the lifting direction of the center of gravity of the hanging frame, the problem that the placement position of the lifted item deviates from the vertical lifting direction of the lifting cable can be effectively solved.

[0017] 2. By providing an adaptive fixing structure, the upper end of the lifted item is suspended and fixed by the vertical hanging assembly. When the lifted item is lifted, the vertical hanging assembly drives the end stabilizing assembly, and the gravity of the lifted item is reacted on the rubber pad. The rubber pads at both ends are closely attached to the lifted item. Cooperating with the suspension and fixation of the upper end of the lifted item, the lifted item can be stably fixed. Moreover, the rubber pad can elastically contract. On the one hand, it can be attached to an irregular shape, enhancing the adaptability and adjustment function. On the other hand, it can also buffer the vibration or shaking of the lifted item, reducing the operation risk. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As Figures 1-13 shown, a hoisting sling for a lifting machine with planar deviation correction and elastic buffer fixation includes a suspension frame, and a planar adjustment structure is arranged on the suspension frame. The planar adjustment structure includes a second cover plate 27 that can move in a state parallel to the ground at both ends, and the gravity lifting direction of the second cover plate 27 is vertically parallel to the gravity lifting direction of the suspension frame. An adaptive fixation structure is arranged at the lower end of the second cover plate 27. The adaptive fixation structure includes a vertical hanging component and an end stabilizing component that cooperates with the vertical hanging component. The end stabilizing component includes a rubber pad 9 that can elastically fit against the side wall of the article to increase the frictional resistance, and the rubber pad 9 can adaptively rotate according to the gravity center of the article.

[0033] When the present invention is in use, the hanging bracket is installed on the lifting equipment. According to the position of the lifted item, the planar adjustment structure is controlled to work. The second cover plate 27 moves in a plane, and the second cover plate 27 is adjusted and moved directly above the lifted item. Moreover, since the lifting direction of the center of gravity of the second cover plate 27 is vertically parallel to the lifting direction of the center of gravity of the hanging bracket, the problem that the placement position of the lifted item deviates from the vertical lifting direction of the lifting cable 1 on the lifting equipment can be effectively solved. It can effectively solve the problem that the lifted item will swing during the process of correcting the vertical lifting direction along with the lifting cable 1 when leaving the ground, and it is very easy to hit the staff on the ground, causing safety accidents. When it is necessary to lift the lifted item, the adaptive fixing structure can be controlled to work, and the vertical hanging component is used to suspend and fix the upper end of the lifted item. When the lifted item is being lifted, the vertical hanging component drives the end stabilizing component, and the gravity of the lifted item acts on the rubber pad 9 in a reaction manner. The rubber pads 9 at both ends are closely attached to the lifted item. Cooperating with the suspension and fixation of the upper end of the lifted item, the lifted item can be stably fixed. Moreover, the rubber pad 9 can elastically contract. On the one hand, it can fit the irregular shape of the side wall of the lifted item, enhancing the adaptability and adjustment function. On the other hand, it can also buffer the vibration or shaking of the lifted item, reducing the risk of operation.

[0034] The planar adjustment structure further includes a first cover plate 3. The lower end of the first cover plate 3 is rotatably connected to a first rotating column 20. Both ends of the first rotating column 20 are respectively fixedly connected with inclined support cylinders 17. The inner wall of the inclined support cylinder 17 is slidably connected with inclined support columns 18. The lower end of the first cover plate 3 is further provided with a second rotating column 21 parallel to the first rotating column 20. Both ends of the second rotating column 21 are respectively provided with the inclined support columns 18. A rotating shaft block fixedly connected with the first cover plate 3 is arranged between the first rotating column 20 and the second rotating column 21. A fixed gear 25 is fixedly arranged inside the rotating shaft block. L-shaped rods 19 are respectively rotatably arranged at both ends of the rotating shaft block. A rotating gear 26 belt-driven with the fixed gear 25 is arranged at the bent part of the L-shaped rod 19. The ends of the L-shaped rods 19 are respectively rotatably arranged on the second rotating column 21. The rotating gear 26 is coaxially fixedly arranged on the second cover plate 27.

[0035] Such as Figures 2-6As shown in FIGS. 12 and 13, according to the position of the lifted object deviating from the lifting equipment, the first rotating column 20 at the lower end of the first cover plate 3 is self-locked and deflected. During the rotation of the first rotating column 20, the diagonal support cylinders 17 at both ends are respectively driven to deflect. The diagonal support cylinders 17 correspondingly drive the diagonal support columns 18 to deflect synchronously. During the deflection of the diagonal support columns 18, the second rotating column 21 is swung and rotated. The second rotating column 21 synchronously drives the L-shaped rods 19 at both ends to deflect with the connection with the rotating shaft block as the axis. During the deflection of the L-shaped rods 19, the rotating gear 26 is driven to deflect. Since the rotating gear 26 and the second cover plate 27 are coaxially fixedly connected, the rotating gear 26 drives the second cover plate 27 to deflect in position. However, since the position of the fixed gear 25 is fixed and a chain belt 24 is provided on the fixed gear 25 and the rotating gear 26, during the position deflection of the second cover plate 27 with the rotating gear 26, due to the action of the chain belt 24 and the fixed gear 25, the rotating gear 26 rotates self, and the rotating gear 26 drives the second cover plate 27 to deflect in another direction, for correcting the deflection direction of the second cover plate 27 and keeping the second cover plate 27 in a state parallel to the ground all the time.

[0036] The end stabilizing assembly further includes a first lower support rod 12 and a second lower support rod 37 rotatably connected to the lower end of the second cover plate 27. First incomplete gears 35 and second incomplete gears 36 that are meshed with each other are coaxially and fixedly arranged at the upper ends of the first lower support rod 12 and the second lower support rod 37 respectively. First upper support rods 11 and second upper support rods 38 are symmetrically arranged at both ends of the second cover plate 27. The first upper support rod 11 and the first lower support rod 12 are kept in a parallel state and are both rotatably arranged on the third cover plate 7. The second upper support rod 38 and the second lower support rod 37 are kept in a parallel state and are both rotatably arranged on another symmetrically arranged third cover plate 7.

[0037] As Figure 2 and 8 shown, during the process of the first lower support rod 12 and the second lower support rod 37 being pressed and deflected downward, under the action of the first incomplete gear 35 and the second incomplete gear 36, the first lower support rod 12 and the second lower support rod 37 deflect towards each other with the same angle stability. During the process of the first lower support rod 12 and the second lower support rod 37 deflecting downward, they respectively drive the first upper support rod 11 and the second upper support rod 38 to deflect synchronously. The first lower support rod 12, the first upper support rod 11, the second upper support rod 38, and the second lower support rod 37 synchronously drive the third cover plates 7 at both ends to move obliquely downward while keeping parallel to the ground.

[0038] A support plate 8 is fixedly provided at the lower end of the third cover plate 7, and a rotating plate 10 is positioned and rotatably provided on the inner side surface of the support plate 8. A plurality of air pressure cylinders 31 are evenly provided on the rotating plate 10, and the air pressure cylinders 31 are communicated with each other by means of through pipes 33. An air pressure block 32 is slidably provided in the air pressure cylinder 31, and a sealing rubber pad 34 is provided at the inner end of the air pressure block 32 for sealing and compressing with the air in the air pressure cylinder 31, and the outer ends of the air pressure blocks 32 are fixedly provided on the rubber pad 9.

[0039] like Figure 2 and 11 As shown in 12, the third cover plate 7 drives the support plate 8 to move obliquely downward, which can respectively drive the rotating plates 10 at both ends to move in the center. The rotating plate 10 drives the air pressure cylinder 31 and the air pressure block 32 to clamp the lifted object in the center. During the clamping process, the rubber pad 9 on the air pressure block 32 can be deformed according to the irregular shape of the lifted object for fitting, thereby increasing the contact area. At the same time, during the extrusion and clamping process, the rubber pad 9 drives the air pressure block 32 to move in the opposite direction, and the air pressure block 32 is used to compress the gas in the air pressure cylinder 31, thereby realizing the effect of air pressure buffering, which can effectively buffer the shaking of the lifted object. Moreover, since the air pressure cylinders 31 are connected by the through pipes 33, the irregular-shaped protrusions of the lifted object have different squeezing degrees on different positions of the rubber pad 9, and the squeezing degrees of different positions of the rubber pad 9 will react on the compression degree of the gas in the air pressure cylinder 31 by the air pressure block 32, thereby causing the rubber pad 9 to fill the irregular-shaped concave blocks, thereby increasing the contact surface, improving the friction force, and maintaining the stability of the lifted object.

[0040] The vertical hanging assembly also includes a sliding plate 13 arranged between the first lower support rod 12 and the second lower support rod 37, and the two ends of the sliding plate 13 are respectively fixedly connected with side frame rods 15, and the upper ends of the side frame rods 15 at both ends of the sliding plate 13 are respectively provided with pins 16 slidably connected to the inner walls of the first lower support rod 12 and the second lower support rod 37, and a hook 14 connected to the sliding plate 13 is provided between the side frame rods 15.

[0041] like Figure 2 and 9 As shown, the hook 14 can be hung on the lifting object. When the lifting object is lifted, due to the influence of the weight of the lifting object, the hook 14 drives the sliding plate 13 to move downward, and the sliding plate 13 drives the side frame rods 15 at both ends to slide down respectively, and the side frame rods 15 drive the pins 16 to slide down along the inner walls of the first lower support rod 12 and the second lower support rod 37 respectively. Since the length of the sliding plate 13 is fixed, the sliding plate 13 drives the first lower support rod 12 and the second lower support rod 37 to deflect toward the center.

[0042] A worm gear 29 is rotatably connected to the support plate 8. The worm gear 29 meshes with a worm wheel 30 that is rotatably connected to the support plate 8. The worm wheel 30 is fixedly connected coaxially with the rotating plate 10.

[0043] As Figure 10 shown, a rotating handle 28 is provided at one end of the worm gear 29. The worm gear 29 is driven to rotate by itself through the rotating handle 28. The worm gear 29 drives the worm wheel 30 to rotate, and the worm wheel 30 drives the rotating plate 10 to deflect, so as to change the fitting angle according to the shape of the lifted item and increase the fitting area.

[0044] The hanging frame includes a number of upright columns 4 that are respectively arranged equidistantly on the first cover plate 3. A column rod 5 is fixedly installed on the upright column 4. The column rods 5 are all fixedly arranged on the mounting column 6, and a lifting cable 1 is arranged on the mounting column 6.

[0045] As Figure 1 shown, the upright columns 4 and the column rods 5 are fixedly arranged on the first cover plate 3, and the column rods 5 are arranged equidistantly on the mounting column 6. The lifting cable 1 of the lifting equipment is arranged on the mounting column 6 to ensure the stability of lifting the first cover plate 3.

[0046] A motor 2 is provided at the upper end of the first cover plate 3. The output end of the motor 2 is provided with a driving bevel gear 22 that is rotatably connected to the first cover plate 3. The driving bevel gear 22 meshes with a driven bevel gear 23, and the driven bevel gear 23 is fixedly arranged on the first rotating column 20.

[0047] As Figure 1 and 5 shown, when the motor 2 works, the output end of the motor 2 drives the driving bevel gear 22 to rotate. The driving bevel gear 22 drives the driven bevel gear 23 to rotate, and the driven bevel gear 23 drives the first rotating column 20 to rotate by itself. Moreover, the motor 2 adopts a stepping motor 2 with a self-locking function to ensure the positioning rotation of the first rotating column 20.

[0048] The working process of the present invention is as follows: When the present invention is in use, the column 4 and the column rod 5 are fixedly arranged on the first cover plate 3, and the column rods 5 are arranged equidistantly on the mounting column 6. The lifting cable 1 of the lifting equipment is arranged on the mounting column 6. According to the position of the lifted item deviating from the lifting equipment, the motor 2 is controlled to work. The output end of the motor 2 drives the driving bevel gear 22 to rotate, the driving bevel gear 22 drives the driven bevel gear 23 to rotate, and the driven bevel gear 23 drives the first rotating column 20 at the lower end of the first cover plate 3 to deflect in a self-locking manner. During the rotation of the first rotating column 20, the diagonal support cylinders 17 at both ends are respectively driven to deflect. The diagonal support cylinder 17 correspondingly drives the diagonal support column 18 to deflect synchronously. During the deflection process, the diagonal support column 18 can slide along the inner wall of the diagonal support cylinder 17 to adapt to the change in distance. During the deflection process of the diagonal support column 18, the second rotating column 21 is driven to swing, and the second rotating column 21 synchronously drives the L-shaped rods 19 at both ends to deflect with the connection point with the rotating shaft block as the axis. During the deflection process of the L-shaped rod 19, the rotating gear 26 is driven to deflect. Since the rotating gear 26 and the second cover plate 27 are coaxially fixedly connected, the rotating gear 26 drives the second cover plate 27 to deflect in position. However, since the position of the fixed gear 25 is fixed, and a chain belt 24 is arranged on the fixed gear 25 and the rotating gear 26, during the process of the L-shaped rod 19 driving the rotating gear 26 to deflect in position, due to the action of the chain belt 24 and the fixed gear 25, the rotating gear 26 rotates self, and the rotating gear 26 drives the second cover plate 27 to deflect in another direction to correct the deflection direction of the second cover plate 27, and keep the second cover plate 27 always parallel to the ground.

[0049] The hook 14 can be hung on the lifted item. When lifting the lifted item, due to the influence of the weight of the lifted item, the hook 14 drives the sliding lifting plate 13 to move downward. The sliding lifting plate 13 respectively drives the side frame rods 15 at both ends to slide downward. The side frame rods 15 respectively drive the pin columns 16 to slide along the inner walls of the first lower support rod 12 and the second lower support rod 37. Since the length of the sliding lifting plate 13 is fixed, when the sliding lifting plate 13 respectively drives the first lower support rod 12 and the second lower support rod 37 to deflect towards the center, during the process of the first lower support rod 12 and the second lower support rod 37 being pressed and deflecting downward, under the action of the first incomplete gear 35 and the second incomplete gear 36, the first lower support rod 12 and the second lower support rod 37 deflect stably at the same angle. During the process of the first lower support rod 12 and the second lower support rod 37 deflecting downward, under the connection action of the third cover plate 7, the first upper support rod 11 and the second upper support rod 38 are respectively driven to deflect synchronously. The first lower support rod 12, the first upper support rod 11, the second upper support rod 38 and the second lower support rod 37 synchronously drive the third cover plates 7 at both ends to move obliquely downward while keeping parallel to the ground.

[0050] During the process of the third cover plate 7 driving the support plate 8 to move obliquely downward, the rotating plates 10 at both ends can be driven to move centrally respectively. The rotating plates 10 drive the pneumatic cylinders 31 and the pneumatic blocks 32 to clamp the lifted item centrally. During the clamping process, the rubber pads 9 on the pneumatic blocks 32 can deform according to the irregular shape of the lifted item for fitting, increasing the contact area. At the same time, during the extrusion clamping process, the rubber pads 9 drive the pneumatic blocks 32 to move in the reverse direction, using the pneumatic blocks 32 to compress the gas in the pneumatic cylinders 31, thereby realizing the function of pneumatic buffering, effectively buffering the shaking of the lifted item. And because the pneumatic cylinders 31 are connected through the connecting pipe 33, due to the different extrusion degrees of the irregularly shaped raised blocks on different positions of the rubber pads 9, the extrusion degrees of different positions of the rubber pads 9 will act on the compression degree of the gas in the pneumatic cylinders 31 by the pneumatic blocks 32 in the reverse direction, so that the rubber pads 9 fill the irregularly shaped concave raised blocks, increasing the contact surface and improving the friction force to maintain the stability of the lifted item.

[0051] The rotating handle 28 drives the worm 29 to rotate self - rotatably. The worm 29 drives the worm wheel 30 to rotate. The worm wheel 30 drives the rotating plate 10 to deflect, for changing the fitting angle according to the shape of the lifted item and increasing the fitting area.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes can be made therein without departing from the principles and spirit of the invention. The scope of the invention is defined by the appended claims and their equivalents.
