Description

Technical Field

[0001] The present application relates to the technical field of military shelter hoisting, and specifically discloses an adjustable beam hoist for a military shelter. Background Art

[0002] A military shelter beam sling is a lifting device used to connect lifting equipment to a military shelter. It typically consists of a beam and specialized rigging. The beam is the primary load-bearing component of the sling, and specialized rigging connects the lifting equipment hook, beam, and shelter.

[0003] The container hoist used in the prior art usually uses a rotary lock to connect with the standard corner pieces at the four corners of the container end beam for hoisting. It has a complex structure, large size, and is inconvenient to use and transport. At the same time, when transporting between roads, railways, and ships, affected by factors such as lifting height, factory space, and transportation load restrictions, the lifting points of military container hoists are usually set at the bottom of the container, and require a special hoist with a simple structure and small size as a transfer tool. In addition, in the production and manufacturing of military container hoists, there is a certain deviation between the actual center of mass of the finished product and the theoretical design center of mass position. The position of the synthetic center of mass of the container loaded with different products will also change with the different products loaded. Using a beam hoist without adjustment function to hoist the container will result in unbalanced load, tilting, unstable lifting, etc., which seriously affects the hoisting safety and is not conducive to protecting the products loaded in the container. In view of this, the inventor has proposed an adjustable beam hoist for military container hoists. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of traditional military shelter lifting equipment such as unbalanced load tilting, unstable lifting and affecting lifting safety.

[0005] In order to achieve the above object, the present invention provides the following basic scheme:

[0006] An adjustable beam-type sling for a military shelter comprises symmetrically arranged sling beams and a main sling and an auxiliary sling detachably connected to the sling beams. The sling beams are symmetrically and detachably connected to main pins for fixing the main slings. Outer walls of the sling beams, which are spaced apart from each other, are each provided with an upper pin and a lower pin symmetrically arranged below the upper pin. The upper pin is sleeved with an anti-sliding block. Side walls of the sling beam are provided with a rotation-stop assembly for preventing the lower pin from rotating.

[0007] It also includes a lifting assembly arranged at both ends of the auxiliary sling, the lifting assembly includes a rotary lock seat detachably connected to the end of the auxiliary sling, a standard lifting angle piece detachably connected to the rotary lock seat, and an adjustment handle for adjusting the angle of the rotary lock seat.

[0008] The principles and effects of this basic solution are:

[0009] 1. Compared with the prior art, the present invention can quickly connect to the lifting equipment by using a soft main sling, reducing the overall size of the sling, and can adapt to the hook forms of various lifting equipment. In use, the function is more comprehensive, and the main sling is installed on the kingpin shaft that is symmetrically and detachably connected to the lifting beam, which makes the main sling more convenient to install and the kingpin shaft is more firmly fixed.

[0010] 2. Compared with the prior art, the present invention forms a movable pin structure by arranging an upper pin and a lower pin on the lifting beam, and the auxiliary sling is installed between the upper pin and the lower pin, which can quickly adjust the sling to the center of mass position of the military cabin, avoiding the unstable lifting and tilting of the military cabin caused by the change of the center of mass position of the military cabin due to loading different products, ensuring that the military cabin can be lifted stably, and meeting the requirements of multiple uses of one military cabin and multiple uses of one sling.

[0011] 3. Compared with the prior art, the lifting assembly provided in the present invention can install the auxiliary sling through the fixed pin shaft when not hoisted. When hoisting is required, the angle of the rotary lock seat is adjusted by adjusting the handle so that the rotary lock seat is locked with the standard lifting angle piece for lifting. This makes the installation of the auxiliary sling more convenient and the fixation of the standard lifting angle piece more secure, thereby ensuring stability during hoisting.

[0012] Furthermore, the anti-rotation assembly includes inserts symmetrically fixed to the four corners of the beam's sidewall and insert plates that plug into the inserts. The inserts are welded to the beam, and nylon pads are symmetrically fixed to the bottom of the beam. Inserting the insert plates into the inserts welded to the ends of the beam prevents the lower pin from falling out and rotating during lifting. Removing the insert plates from the insert blocks allows for quick removal of the lower pin, facilitating the rapid replacement of lifting straps of varying lengths.

[0013] Furthermore, the rotary lock seat is rotatably connected to a rotary lock core shaft, the standard lifting angle piece is machined with a side hole threadedly connected to the rotary lock core shaft, and the handle is welded to the side wall of the rotary lock seat. The rotary lock core shaft can drive the rotary lock seat to rotate and fix it to the standard lifting angle piece.

[0014] Furthermore, the hanging beam is a spliced ​​box-shaped load-bearing member, which is more convenient and quick to install and has a good load-bearing effect.

[0015] Furthermore, the main sling is folded in half and passed through the sling beam to be connected to the hook of the lifting device. The main sling is a soft sling. The soft main sling connects the entire sling to the lifting device to achieve the lifting function.

[0016] Furthermore, the auxiliary sling passes between the upper and lower pins, allowing it to shuttle between the upper and lower pins when unloaded. By passing the auxiliary sling between the upper and lower pins, the left and right ends of the auxiliary sling can be quickly adjusted, thereby changing the position of the sling during lifting to achieve balance.

[0017] Furthermore, the anti-sliding block is made of nylon plastic, and the upper portion of the anti-sliding block is cut into a flat edge. During hoisting, the anti-sliding block can limit the sliding of the soft loaded auxiliary sling, thereby ensuring safety during hoisting. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Implementation example Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown:

[0028] A military square cabin adjustable beam-type sling includes two symmetrically arranged sling beams 3. The sling beams 3 are spliced ​​box-shaped load-bearing components, which are easy to install and have good load-bearing effect. The upper ends of the sling beams 3 are detachably connected with the main pin shaft 2, and the main pin shaft 2 is fixed to the sling beam 3 by a locking nut. The sling beams 3 are all sleeved with a main sling 1 through the main pin shaft 2. The main sling 1 is folded in half and passes through the main pin shaft 2. When lifting, the main sling 1 is connected to the hook of the lifting equipment for lifting. The main sling 1 can be applied to the hook forms of various lifting equipment and is easy to install.

[0029] The outer side wall of the hanging beam 3 can be detachably connected with an upper pin shaft 6, and the lower side of the upper pin shaft 6 is symmetrically provided with a lower pin shaft 7 that can be detachably connected to the outer side wall of the hanging beam 3. The upper pin shaft 6 and the lower pin shaft 7 are fixed to the hanging beam 3 by a pressure plate 12 to complete the fixation. A secondary sling 4 is provided between the upper pin shaft 6 and the lower pin shaft 7. When the secondary sling 4 is not loaded, the secondary sling 4 can shuttle and move to adjust the length of the left and right ends of the secondary sling 4. An anti-sliding block 9 is provided on the upper pin shaft 6. The anti-sliding block 9 is made of nylon plastic. The upper part of the anti-sliding block 9 is cut into a flat end. When loaded, the flat end of the anti-sliding block 9 is tightly attached to the plane of the hanging beam 3, thereby preventing the secondary sling 4 from sliding and ensuring the lifting. In order to ensure the stability and safety of the lifting beam 3, the side wall of the lifting beam 3 is provided with a rotation-stop assembly, which includes plug blocks 11 symmetrically fixed to the four corners of the side wall of the lifting beam 3 and plug plates 10 plugged into the plug blocks 11. The plug blocks 11 are fixed to the lifting beam 3 by welding. The plug plates 10 are inserted into the plug blocks 11 welded to the ends of the lifting beam 3 to prevent the lower pin shaft 7 from falling off and rotating during the lifting process. When the plug plate 10 in the plug block 11 is pulled out, the lower pin shaft 7 can be quickly pulled out, which is convenient for quickly replacing lifting slings of different lengths. Nylon pads 8 are symmetrically fixed to the bottom of the lifting beam 3. The provided nylon pads 8 facilitate the direct placement of the lifting beam 3 on the upper part of the military cabin to avoid collision with the sling and the military cabin.

[0030] The embodiment also includes a lifting assembly 5 provided at both ends of the auxiliary sling 4. There are four lifting assemblies 5 installed on the four bottom feet of the military shelter. The lifting assembly 5 includes a rotary lock seat 13 detachably connected to the end of the auxiliary sling 4, a rotary lock core shaft 15 rotatably connected to the rotary lock seat 13, a standard lifting angle piece 17 threadedly connected to the rotary lock core shaft 15, and an adjustment handle 16 welded to the side wall of the rotary lock seat 13 and used to adjust the angle of the rotary lock seat 13. The side wall of the rotary lock core shaft 15 is opened. There is an adjustment hole, and the side wall of the standard lifting angle piece 17 is processed with a side hole threadedly connected to the rotary lock core shaft 15, so that the rotary lock seat 13 and the standard lifting angle piece 17 can be connected through the rotary lock core shaft 15. The rotary lock core shaft 15 can be driven to rotate through the adjustment hole, so that the rotary lock core shaft 15 drives the rotary lock seat 13 and the standard lifting angle piece 17 to be firmly fixed, so as to carry out lifting. The upper end of the rotary lock seat 13 is detachably connected to the fixed pin shaft 14, and the fixed pin shaft 14 is used to fix the auxiliary sling 4.

[0031] Specific implementation steps:

[0032] Step 1: Place the main sling 1 on the upper end of the hanging beam 3, and then install the two main pin shafts 2 on the upper end of the hanging beam 3 to fix the main hanging beam 3;

[0033] The second step is to fix the auxiliary sling 4 to the upper side wall of the lower pin 7 and the lower side wall of the upper pin 6 when hoisting is required, so that the auxiliary sling 4 is located between the upper pin 6 and the lower pin 7. Adjust the length of both ends of the auxiliary sling 4, and then adjust the slider so that the flat end of the slider is aligned with the plane of the lifting beam 3. This will prevent the slider from rotating further under load, thereby preventing the auxiliary sling 4 from sliding.

[0034] The third step is to insert the two ends of the auxiliary sling 4 into the rotary lock seat 13 respectively, and then fix the auxiliary sling 4 by fixing the pin shaft 14;

[0035] In the fourth step, when the military shelter needs to be hoisted, the rotary lock core shaft 15 is rotated by adjusting the handle 16 until the adjusting handle 16 is rotated to a horizontal state, and the rotary lock seat 13 is fixed to the standard lifting angle piece 17. The lifting device pulls up the main lifting belt 1 to drive the four lifting components 5 to complete the lifting of the military shelter.
