Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, in particular to a stable cargo hoisting equipment. Background Art

[0002] Lifting equipment refers to mechanical equipment used to lift and move heavy objects from one place to another. These equipment are widely used in many fields such as construction, manufacturing, logistics, energy, aerospace, etc. to complete various lifting operations efficiently and safely. When lifting objects wrapped in mesh bags, a cargo stabilizing lifting equipment is used.

[0003] The lifting equipment usually consists of a movable support frame, which is driven by a motor to rotate the winding roller, and is retracted and released by a pull rope wrapped around the surface of the winding roller. The object wrapped in the net bag is hooked by a hook fixed to the other end of the pull rope, and the lifting operation of the object wrapped in the net bag is completed. Usually, the lifting equipment has four hooks, and the objects wrapped in the net bag are lifted by the four hooks at the same time to increase the stability of the lifting. When four hooks are used to lift the object wrapped in the net bag, if the braking device fails, the winding roller cannot be braked in time when it loses control, which is likely to increase the occurrence of safety accidents.

The inner wall of the support box 2101 is rotatably connected with a half gear 2105. The surface of the half gear 2105 and the surface of the winding roller 113 are fixedly installed with a second synchronous wheel 2106. The surface of the second synchronous wheel 2106 is movably sleeved with a second synchronous belt 2107. The two second synchronous wheels 2106 are connected by the second synchronous belt 2107. The inner wall of the support box 2101 is slidably connected with a U-shaped tooth plate 2108. The U-shaped tooth plate 2108 cooperates with the teeth of the half gear 2105 to support the box 2101. A first spring 2109 is provided on one side of the support box 2101, one end of the first spring 2109 is fixedly connected to one side of the support box 2101, the other end of the first spring 2109 is fixedly connected to the inner side of the U-shaped tooth plate 2108, a positioning groove 2110 is provided on the top of the U-shaped tooth plate 2108, a positioning button 2111 is slidably connected to the inner cavity of the positioning groove 2110, a second spring 2112 is provided in the inner cavity of the positioning groove 2110, one end of the second spring 2112 is fixedly connected to the inner wall of the positioning groove 2110, and the second spring The other end of the spring 2112 is fixedly connected to the bottom of the positioning button 2111. A positioning hole 2113 is formed on the inner wall of the support box 2101. The inner cavity of the positioning hole 2113 cooperates with the surface of the positioning button 2111. By providing the limiting unit 21, the locking function can be quickly activated when the pull rope 115 is suddenly and quickly lowered, limiting the further movement of the pull rope 115, thereby preventing dangerous situations that may be caused by gravity acceleration. This automated safety protection measure greatly improves the safety and reliability of the lifting operation.

[0039] A guide groove 2114 is formed on the surface of the support box 2101, and a guide block 2115 is fixedly mounted on the surface of the U-shaped tooth plate 2108. The surface of the guide block 2115 is slidably connected to the inner cavity of the guide groove 2114. The sliding connection between the guide groove 2114 and the guide block 2115 can guide the movement of the U-shaped tooth plate 2108, so that the U-shaped tooth plate 2108 can move horizontally.

[0040] A telescopic rod 2116 is fixedly mounted on one side of the support box 2101. The telescopic end of the telescopic rod 2116 is fixedly connected to the inner side of the U-shaped tooth plate 2108. The inner cavity of the first spring 2109 is sleeved on the surface of the telescopic rod 2116. By providing the telescopic rod 2116, the compression of the first spring 2109 can be guided, so that the first spring 2109 can be compressed and stretched horizontally.

[0041] The specific implementation of this embodiment is as follows: when the object wrapped in the mesh bag is hoisted, the second motor 19 is started, and the second motor 19 drives the screw rod 110 to rotate, and the screw rod 110 is supported by the support plate 18. The support frame 111 is connected to the screw rod 110 through rotation, and the support frame 111 can be driven to move. The position of the hook 303 can be adjusted according to the placement position of the object wrapped in the mesh bag, so that the hook 303 is vertically above the object wrapped in the mesh bag, and the third motor 112 is started. The winding roller 113 is driven to rotate by the third motor 112, and the two winding rollers 113 can be moved in opposite directions through the engagement of the first gear 114. The three-axis direction of the winding roller 113 is opposite to each other, so that when the third motor 112 drives the winding roller 113 to rotate, the four ropes 115 can be released or collected at the same time. In the process of releasing the ropes, the third fixing frame 2104 is fixedly connected to the surface of the rope 115, and the rope 115 will move outward in advance. At the same time, the rotation of the first gear 114 can drive the second synchronous wheel 2106 connected to the winding roller 113 to rotate. The second synchronous belt 2107 can drive the second synchronous wheel 2106 connected to the half gear 2105 to rotate, and then drive The half gear 2105 starts to rotate, and the meshing of the half gear 2105 and the U-shaped tooth plate 2108 can drive the U-shaped tooth plate 2108 to slide with one end of the inner wall of the support box 2101. When the toothless part of the half gear 2105 coincides with the top of the U-shaped tooth plate 2108, the U-shaped tooth plate 2108 can be reset under the reaction force generated by the compression of the first spring 2109. When the pull rope 115 is working normally, the pull rope 115 will slowly reel in and release the rope. During this process, the inertia generated by the movement of the U-shaped tooth plate 2108 is small, so that the opening of the positioning groove 2110 and the opening of the positioning hole 2113 are staggered with each other, thereby avoiding positioning The button 2111 enters the inner cavity of the positioning hole 2113. When the winding roller 113 suddenly releases the rope, under the action of gravity, the pull rope 115 will quickly release the rope downward, thereby driving the half gear 2105 to rotate quickly, so that the inertia generated when the U-shaped tooth plate 2108 moves toward the inner cavity of the support box 2101 is large, which can make the positioning groove 2110 coincide with the opening of the positioning hole 2113. After the coincidence, under the reaction force of the second spring 2112, the positioning button 2111 can be pushed into the inner cavity of the positioning hole 2113, completing the position fixation of the second fixing frame 2103, thereby limiting the downward movement distance of the pull rope 115, thereby ensuring the safety of the equipment.

[0042] Example 2: Please refer to Figure 7 and Figure 8The present invention provides a technical solution: a stable cargo lifting device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The stabilizing mechanism 2 also includes a connecting unit 22, which is arranged at the bottom of the support frame 111. The connecting unit 22 is used to further increase the stability of the pull rope 115.

[0043] As a further definition of the stabilizing mechanism 2 of the present invention, the connecting unit 22 includes a first connecting block 2201, which is fixedly installed on the bottom of the first fixing frame 2102 and the second fixing frame 2103, and a movable groove 2202 is provided on the top of the second fixing frame 2103 and the third fixing frame 2104. The inner cavity of the movable groove 2202 is slidably connected to the second connecting block 2203, and the inner wall of the first connecting block 2201 is rotatably connected to the connecting rod 2204. The surface of the connecting rod 2204 is rotatably connected to the inner wall of the second connecting block 2203. By providing the connecting unit 22, the pull rope 115 can be restricted while reducing the shaking between the pull ropes 115, which helps to maintain the balance and stability of the pull rope 115 during the rope release process, prevents the object wrapped in the net bag from shaking when it is lifted, and further improves the stability of the pull rope 115 during operation;

[0044] A limiting groove 2205 is provided on the inner wall of the movable groove 2202, and a limiting block 2206 is fixedly installed on the surface of the second connecting block 2203. The surface of the limiting block 2206 is slidably connected to the inner cavity of the limiting groove 2205. Through the sliding connection between the limiting groove 2205 and the limiting block 2206, the second connecting block 2203 can be guided when moving, and at the same time, the second connecting block 2203 can be prevented from separating from the movable groove 2202.

[0045] The specific implementation of this embodiment is as follows: in the process of the second fixing frame 2103 moving downward, the second connecting block 2203 can be driven to move downward. Due to the rotation connection between the second connecting block 2203 and the connecting rod 2204, the angle of the connecting rod 2204 in the second connecting block 2203 can be changed, thereby forcing the angle of the connecting rod 2204 and the first connecting block 2201 to change. Through the sliding connection between the second connecting block 2203 and the movable groove 2202, the position of the second connecting block 2203 on the top of the second fixing frame 2103 or the first fixing frame 2102 can be changed according to the change of the angle of the connecting rod 2204, thereby avoiding the jamming phenomenon. The two adjacent second fixing frames 2103 are connected through the connecting rod 2204, so that the bottom of the second fixing frame 2103 is connected to the top of the third fixing frame 2104, and the top of the second fixing frame 2103 is connected to the bottom of the first fixing frame 2102, thereby increasing the stability of the second fixing frame 2103 during operation. The second fixing frame 2103 is used to limit the distance between the pull ropes 115. At the same time, the pull ropes 115 can be restricted while reducing the shaking between the pull ropes 115, which helps to maintain the balance and stability of the pull ropes 115 during the rope release process, prevents the objects wrapped in the net bag from shaking when they are lifted, and further improves the stability of the pull ropes 115 during operation.

[0046] Example 3: Please refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The present invention provides a technical solution: a stable cargo lifting device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A fixing mechanism 3 is provided at the other end of the pull rope 115, and the fixing mechanism 3 is used to increase the stability when lifting the cargo.

[0047] As a further limitation of the fixing mechanism 3 of the present invention, the fixing mechanism 3 includes a pull rod 301, which is fixedly installed at one end of the pull rope 115, and the surface of the pull rod 301 is slidably connected to a movable block 302, and the inner wall of the movable block 302 is rotatably connected to a hook 303, and the surface of the pull rod 301 and the inner side of the hook 303 are fixedly installed with a docking plate 304, and the inner walls of the two docking plates 304 are rotatably connected to a docking rod 305. By setting the fixing mechanism 3, the four hooks 303 are brought close to each other to realize the lifting of the object wrapped in the net bag, and the position of a hanging place is fixed at the same time by the four hooks 303, which increases the stability during the lifting process, reduces the risk of the object wrapped in the net bag shaking or falling off, and further improves the stability of the equipment when it is working;

[0048] A limiting groove 307 is provided on the inner side of the movable block 302, and a limiting plate 306 is fixedly mounted on the surface of the pull rod 301. The surface of the limiting plate 306 is slidably connected to the inner cavity of the limiting groove 307. The sliding connection between the limiting plate 306 and the limiting groove 307 can guide the movement of the pull rod 301, so that the pull rod 301 remains vertical and moves up and down.

[0049] A third spring 308 is sleeved on the surface of the pull rod 301, one end of the third spring 308 is fixedly connected to the bottom of the movable block 302, and the other end of the third spring 308 is fixedly connected to the top of the docking plate 304. By setting the third spring 308, when the pull rod 301 moves upward, the third spring 308 is squeezed. When the suspension of the object wrapped in the net bag is cancelled, the reaction force of the third spring 308 is used to reset the four hooks 303.

[0050] The specific implementation of this embodiment is as follows: after the pull rope 115 is released, the hook 303 is passed through the net bag of the object wrapped in the net bag, the third motor 112 is started to drive the winding roller 113 to reel in the pull rope 115, driving the pull rope 115 to move upward, and at the same time pulling the pull rod 301. During the upward movement of the pull rod 301, the docking plate 304 fixed to the pull rod 301 is driven to move upward. Due to the rotation connection between the docking plate 304 and the docking rod 305, the angle of the docking rod 305 is changed, so that the hook 303 is moved in the movable block. The inner wall of 302 rotates so that the four hooks 303 approach each other, thereby lifting the object wrapped in the mesh bag. The four hooks 303 simultaneously fix the position of one hanging place, which greatly increases the stability during the lifting process and reduces the risk of the object wrapped in the mesh bag shaking or falling off. The first synchronous wheel 15 is driven to rotate by the first motor 13, and the first synchronous belt 16 drives the first synchronous wheel 15 connected to the rotating column 14 to rotate, thereby changing the hanging position of the support box 2101 and realizing the lifting and transportation of the object wrapped in the mesh bag.
