Description

Technical Field

[0001] The present application relates to the technical field of hoisting structures, and in particular to a hoisting structure and a hoisting method for a hoisting vehicle. Background Art

[0002] Hoisting machinery refers to machinery that uses hooks or other lifting devices to hang heavy objects and perform cyclic operations such as lifting and moving in space. There are many categories of cranes. The common terms such as "crane", "tower crane", "overhead crane" and "crane" refer to one or several types of cranes.

[0003] A lifting device is required when lifting a vehicle. Existing lifting devices generally use a hook to lift the vehicle directly, so the hook and the vehicle are supported by only one steel rope, which reduces the load-bearing capacity of the lifting structure. In addition, the wheels are lifted in a bundling manner, which also reduces the convenience of the lifting structure during lifting and reduces the lifting efficiency of the lifting structure. Summary of the Invention

[0004] In order to improve the load-bearing capacity and lifting efficiency during lifting, the present application provides a lifting structure and a lifting method for a lifting vehicle.

[0005] In a first aspect, the present application provides a lifting structure for a lifting vehicle, which adopts the following technical solution:

[0006] A lifting structure for lifting a vehicle, comprising a hook connected to a lifting device, wherein the hook is provided with a lifting mechanism for connecting to the vehicle, the lifting mechanism comprising:

[0007] A balance beam, wherein the balance beam is in a horizontal state and is provided with connecting plates at both ends;

[0008] Two balancing steel ropes, each of which passes through two connecting plates and is connected to the hook;

[0009] A connecting seat, the connecting seat is used to connect to the vehicle;

[0010] Two connecting steel ropes are respectively passed through the two connecting plates and are respectively detachably connected to the two ends of the connecting seat.

[0011] By adopting the above technical solution, one of the balancing steel ropes is passed through the connecting plate and fixedly connected to the hook, and then the other balancing steel rope is passed through the other connecting plate and fixedly connected to the hook, and then the two connecting steel ropes are respectively passed through the two connecting plates and fixedly connected to the two ends of the connecting seat, and then the vehicle is fixedly installed on the connecting seat. Therefore, the two balancing steel ropes and the two connecting steel ropes are divided into two sections for force distribution, and the force is distributed through the balance beam at the same time, thereby improving the bearing capacity of the lifting structure; at the same time, the connecting seat is adapted to fix different vehicles, so that different connecting seats can be replaced to adapt to different vehicles, further improving the convenience of lifting the vehicle, and improving the lifting efficiency of the lifting structure, and at the same time, the connecting steel rope passes through the connecting plate, so that the connecting steel rope can move and the connecting seat is in a horizontal state, thereby further improving the bearing capacity of the connecting seat and the bearing capacity of the lifting structure.

[0012] Optionally, mounting posts are provided on both ends of the connecting seat, the connecting steel rope is provided with a mounting ring which is sleeved on the mounting post, the mounting post is provided with a positioning component for positioning the mounting ring, and the two connecting steel ropes cross each other and are positioned by a fixing mechanism.

[0013] By adopting the above technical solution, the positioning assembly is unlocked, and then the mounting ring can be removed and replaced with a different connecting seat. The mounting ring is then sleeved on the mounting column and pressed against the connecting seat. The positioning assembly then positions the mounting ring, so that the connecting steel rope pulls the positioning ring to generate a pressing force against the connecting seat, thereby reducing the probability of the positioning ring detaching from the mounting column, and also reducing the pressure borne by the positioning assembly when positioning the mounting ring, thereby improving the positioning effect of the positioning assembly on the mounting ring, improving the load-bearing capacity of the lifting structure, and the fixing mechanism improves the stability of the two connecting steel ropes, thereby improving the load-bearing capacity during lifting.

[0014] Optionally, the positioning component includes:

[0015] A positioning ring, which is sleeved on the mounting post and presses against the mounting ring for positioning;

[0016] A positioning screw passes through the positioning ring and is threadedly connected to the mounting post for positioning.

[0017] By adopting the above technical solution, after the positioning screw is turned to disengage from the mounting column, the mounting ring and the positioning ring can be removed. When fixing is required, the positioning ring is put on the mounting column and pressed against the mounting ring for positioning. Then the positioning screw is turned to be threadedly connected to the mounting column for positioning, thereby achieving the positioning of the mounting ring.

[0018] By adopting the above technical solution, the fixing mechanism includes:

[0019] A fixed block, wherein two opposite side walls of the fixed block are provided with placement grooves for placing the connecting steel rope;

[0020] A locking assembly is provided on the fixing block and restricts the connecting steel rope to the placement groove.

[0021] Optionally, the two connecting steel ropes are placed on the two placement grooves, and the locking assembly is activated to restrict the two connecting steel ropes to the placement grooves, so as to lock the connecting steel ropes and improve the load-bearing capacity during lifting; and the connecting steel ropes can also slide on the placement grooves, so when replacing the connecting seat, pulling the two connecting steel ropes will push the fixed block to slide and avoid the position, so that the distance between the bottom ends of the two connecting steel ropes can be increased without removing the fixed block during replacement. After the replacement is completed, the fixed block moves downward under the action of gravity to position the two connecting steel ropes, further improving the convenience during replacement and improving the lifting efficiency of the lifting structure.

[0022] Optionally, two locking assemblies are provided, and the locking assemblies include:

[0023] A rotating plate is rotatably mounted on the fixed block and is mounted on the fixed block and cooperates with the fixed block to restrict the connecting steel rope to the placement groove. After the rotating plate rotates away from the fixed block, the connecting steel rope can be removed from the placement groove;

[0024] A locking rod, the locking rod being arranged on the fixed block, and the rotating plate being provided with a rotation slot for the locking rod to rotate into;

[0025] A locking nut is threadedly connected to the locking rod and pressed against the rotating plate for positioning.

[0026] By adopting the above technical solution, the locking nut is turned away from the rotating plate, and then the rotating plate can be rotated away from the connecting steel rope, and then the connecting steel rope is removed from the placement groove. When installation is required, the connecting steel rope is placed on the placement groove, and then the rotating plate is rotated close to the connecting steel rope and erected on the fixed block, and the locking rod is rotated into the rotation groove, and then the locking nut is turned to press against the rotating plate for positioning. Therefore, the two rotating plates restrict the two connecting steel ropes to the placement groove, thereby realizing the positioning of the two connecting steel ropes, reducing the probability of the two crossed connecting steel ropes causing the connecting seat to rotate, improving the stability of the connecting steel ropes, and improving the bearing capacity of the lifting structure.

[0027] Optionally, both rotating plates are provided with toothed portions meshing together.

[0028] By adopting the above technical solution, rotating any one rotating plate can drive the two rotating plates to rotate together, thereby improving the convenience of positioning and unlocking the two connecting steel ropes. Moreover, the two rotating plates rotate together, making the two rotating plates connected as one. When one of the rotating plates is loose, the other rotating plate positions it, thereby improving the positioning effect of the connecting steel ropes and improving the lifting efficiency and load-bearing capacity of the lifting structure.

[0029] Optionally, the acute angle between the two balancing steel ropes is A, and A≤60 degrees.

[0030] By adopting the above technical solution, the tension of the two balancing steel ropes is increased, and the bearing capacity of the hoisting structure is improved.

[0031] Optionally, both ends of the balance beam are provided with limiting components for limiting the two connecting plates respectively, and the limiting components include:

[0032] A limit plate, which is plugged into one end of the balance beam and presses against one end of the balance beam;

[0033] The limiting ring is arranged on the limiting plate and is located between the two connecting plates and is pressed against the connecting plates for positioning.

[0034] By adopting the above technical solution, the two connecting plates generate a component force approaching each other under the action of tension, the limit plate presses against the end of the balance beam for positioning, and the limit ring presses against the connecting plate to prevent the two connecting plates from moving. Therefore, the limit ring positions the connecting plate and disperses the component force of the connecting plate, thereby improving the stability of the connecting plate and the bearing capacity of the lifting structure.

[0035] Optionally, the connecting plates are sleeved on both ends of the balance beam and fixedly connected to the balance beam, and a placement space for the connecting plates to pass through is formed between the limiting plates and the limiting rings.

[0036] By adopting the above technical solution, the connecting plate is fixed, the limiting ring is first put on the balance beam, and then the connecting plate is passed through the insertion space between the limiting plate and the limiting ring and put on the balance beam, and the connecting plate is pushed to push the limiting ring to move. The movement of the limiting ring pushes the limiting plate to be inserted and installed on the end of the balance beam and presses against the end of the balance beam for positioning, so as to realize the positioning of the connecting plate, and finally the connecting plate and the balance beam are fixedly connected together, thereby improving the accuracy of the position of the connecting plate when it is fixed and installed, and improving the bearing capacity of the lifting structure.

[0037] In a second aspect, the present application provides a method for hoisting a vehicle, which adopts the following technical solution:

[0038] A lifting structure and a lifting method for lifting a vehicle, comprising the following steps:

[0039] S1. Replace the appropriate connector according to the vehicle.

[0040] S2. Fix the vehicle by connecting the mold on the connecting seat to the vehicle;

[0041] S3. Lifting the vehicle: the lifting equipment starts the hook to drive the connecting seat and the vehicle upward to achieve lifting.

[0042] In summary, this application includes at least one of the following beneficial technical effects:

[0043] The load-bearing capacity of the lifting structure is improved by dividing the force into two sections through two balancing steel ropes and two connecting steel ropes, and the force is also divided through the balancing beam. At the same time, the connecting seat is used to fix different vehicles, thereby improving the lifting efficiency of the lifting structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Reference Figure 1 and Figure 2 The lifting mechanism 2 includes a balance beam 21, two balance steel ropes 22, a connecting seat 23 and two connecting steel ropes 24. The balance beam 21 is in a horizontal state, and the balance beam 21 can be made of a hollow seamless steel tube; connecting plates 3 are fixedly installed at both ends of the balance beam 21, and the connecting plates 3 are composed of two vertical connecting pieces 31, the bottom ends and the top ends of the two connecting pieces 31 are fixedly connected together, and at the same time, the two connecting pieces 31 cooperate to form a sleeve hole, the two connecting pieces 31 are sleeved on the balance beam 21 through the sleeve hole, and the two connecting pieces 31 are fixedly connected to the balance beam 21, and the top and bottom ends of the two connecting pieces 31 are respectively provided with a first horizontal connecting hole 32 and a second connecting hole 33, and the axes of the first connecting hole 32 and the second connecting hole 33 are perpendicular to the axis of the balance beam 21.

[0054] Reference Figure 1 and Figure 2 , a limiting assembly 4 for limiting the connecting plate 3 is provided at both ends of the balance beam 21, and the limiting assembly 4 includes a limiting plate 41 and a limiting ring 42. The limiting plate 41 is formed by bending to form a limiting portion 411 and two connecting portions 412. The two connecting portions 412 are located at both ends of the limiting portion 411, and the limiting portion 411 is pressed against one end of the balance beam 21 for positioning, and the two connecting portions 412 extend along the axis of the balance beam 21 to the side of the connecting plate 3 away from the limiting portion 411.

[0055] Reference Figure 1 and Figure 2 The limiting posts 43 are fixedly installed on the side walls on the opposite sides of the two limiting parts 411, and the limiting posts 43 are plugged into one end of the balance beam 21, and the limiting part 411 presses against one end of the balance beam 21 for positioning; the limiting ring 42 is fixedly installed on the ends of the two connecting parts 412 away from the limiting part 411, and the limiting ring 42 is sleeved on the balance beam 21. At the same time, the limiting ring 42 and the balance beam 21 are coaxially arranged, and the connecting plate 3 is located between the limiting part 411 and the limiting ring 42, so that the two limiting rings 42 press against the two connecting plates 3 to prevent the two connecting plates 3 from approaching each other; the width of the connecting plate 3 is smaller than the distance between the limiting post 43 and the limiting ring 42, so that a space for the connecting plate 3 to be placed is formed between the limiting plate 41 and the limiting ring 42, so that the connecting plate 3 can be placed between the limiting post 43 and the limiting ring 42.

[0056] Reference Figure 1 and Figure 2 When installing the connecting plate 3, the limiting ring 42 is put on the balance beam 21, and then the connecting plate 3 is placed between the limiting column 43 and the limiting ring 42 and put on the balance beam 21. The connecting plate 3 is pushed to push the limiting ring 42, the limiting part 411 and the limiting column 43 to move, so that the limiting column 43 is plugged into and installed on the balance beam 21, and the limiting part 411 is pressed against the balance beam 21, so as to realize the positioning of the limiting ring 42. Finally, the connecting plate 3 and the balance beam 21 are fixed together by welding or other means, so that the two limiting rings 42 prevent the two connecting plates 3 from approaching each other.

[0057] Reference Figure 1 and Figure 3 The two balancing steel ropes 22 are arranged in a one-to-one correspondence with the two connecting plates 3. The balancing steel ropes 22 are fixedly connected together after passing through the first connecting hole 32 and the hook 1. At the same time, the acute angle between the two balancing steel ropes 22 is A, and A≤60 degrees. The following takes A=60 degrees as an example for explanation. The axial pressure N exerted on the balance beam 21 is N=P×Cos60°=P×0.5. The distance between the bottom ends of the two balancing steel ropes 22 is L. The larger the angle A and the smaller the value of CosA, the smaller the axial pressure N. However, this will also increase the length of L, that is, the length of the balance beam 21 will be increased, thereby leading to an increase in various requirements of the balance beam 21. Therefore, when A=60 degrees, the axial pressure N and the requirements of the balance beam 21 can both meet moderate requirements, thereby improving the bearing capacity of the lifting structure.

[0058] Reference Figure 1 A mold for fixing the vehicle is fixedly installed on the lower surface of the connecting seat 23 to fix the vehicle.

At the same time, the second connecting hole 33 and the mounting ring 12 through which the connecting steel rope 24 passes are respectively located on both sides of the connecting seat 23. The second connecting hole 33 divides the connecting steel rope 24 into a first connecting section 25 and a second connecting section 26. Therefore, the two first connecting sections 25 are arranged to cross each other, and the two second connecting sections 26 are also arranged to cross each other. The mounting ring 12 is sleeved on the mounting post 11, and the mounting ring 12 is pressed against the side wall of the connecting seat 23 for positioning under the tension of the connecting steel rope 24.

[0060] Reference Figure 1 and Figure 2 The mounting column 11 is provided with a positioning assembly 5 for positioning the mounting ring 12.

[0062] Reference Figure 1 and Figure 4 A fixing mechanism 6 for positioning is provided at the intersection of the two first connecting sections 25 and the two second connecting sections 26. The fixing mechanism 6 includes a fixing block 61 and a locking assembly 7. Placement grooves 62 are provided on the two opposite side walls of the fixing block 61. The two placement grooves 62 are in a cross state, so that the two placement grooves 62 are respectively parallel to the axes of the corresponding first connecting sections 25. At the same time, the placement grooves 62 are for the first connecting sections 25 to be placed. Two locking assemblies 7 are provided and are located on the two opposite side walls of the fixing block 61, and the locking assemblies 7 respectively limit the two first connecting sections 25 to the placement grooves 62.

[0064] Reference Figure 1 and Figure 4 , twist the locking nut 73 away from the rotating plate 71, and then pull one of the rotating plates 71 to drive the two rotating plates 71 to rotate away from the mounting block 63 at the same time, and then the first connecting section 25 can be removed. When fixing is needed, the two first connecting sections 25 are placed on the two placement grooves 62 respectively, and then one of the rotating plates 71 is pushed to drive the two rotating plates 71 to be built onto the two mounting blocks 63, and finally, the locking nut 73 is twisted to press against the rotating plate 71 for positioning, so as to achieve positioning of the connecting steel rope 24; and when replacing the connecting seat 23, pulling the two first connecting sections 25 can make the fixing block 61 slide on the two first connecting sections 25 to avoid position.
