Description

Technical Field

[0001] The invention relates to the field of hoisting structures, and in particular to a convenient hoisting auxiliary device. Background Art

[0002] In order to meet various special lifting needs in production and life, the currently popular methods are mainly the following:

[0003] The most common method is to use various slings or special ropes to hang or tie objects. This method is generally suitable for situations where objects only need to be lifted. If there are certain requirements for the direction and tilt angle of the object to be lifted, the difficulty lies in how to hang or tie the object. At this time, this method is time-consuming and laborious, and it takes multiple attempts to meet the lifting requirements.

[0004] Special lifting fixtures are designed for long-term lifting of similar products. According to the actual situation, a set of special auxiliary devices will be designed to reduce the time of hanging or bundling and improve work efficiency. This method is generally only for specific products, so its application is relatively narrow.

[0005] The hooks of the matching rigging and hooks are also auxiliary devices designed to reduce the time of hanging or tying objects. Different rigging is required to adapt to different lifting situations, and the flexibility is poor.

[0006] Certain special lifting operations, such as drop tests, require that the lifted object reach different tilt angles. In the actual production process, the object is simply lifted up by fixing both ends, and continuous attempts to measure are made to determine whether the required tilt angle of the object is achieved. There is no convenient and relatively accurate auxiliary device, which results in low efficiency. Summary of the invention

[0007] The purpose of the present invention is to provide a convenient lifting auxiliary device for quickly adjusting a lifted object to a required tilt angle, thereby solving the problem of low adjustment efficiency in the prior art.

[0008] In order to achieve the above tasks, the present invention adopts the following technical solutions:

[0009] A convenient lifting auxiliary device, which adjusts the inclination angle of a lifted object through two lifting ropes; the device comprises a load-bearing clamp, the cross-section of the load-bearing clamp is a U-shaped structure, and a rope passage for passing a lifting rope is formed inside the load-bearing clamp; a rope clamp is provided on the load-bearing clamp, and a clamping head at the front end of the rope clamp is inserted into the rope passage of the load-bearing clamp, and teeth for locking the lifting rope are provided on the clamping head; a rope hanging plate is fixed to the rear end of the rope clamp, and a rope hanging hole for fixing another lifting rope is opened on the rope hanging plate.

[0010] Furthermore, the U-shaped bending area inside the load-bearing sleeve forms the rope threading path.

[0011] Furthermore, the rope clamp is a plate-like structure made of metal, the front end of which is tilted upward to form the clamping head, the teeth are distributed on the front end surface of the clamping head, and the rear end of the rope clamp is fixed to the rope hanging plate by fixing bolts or welding.

[0012] Furthermore, a clamp is provided on one side of the load-bearing sleeve, and a locking shaft is installed on the clamp through a sleeve, and the front end of the locking shaft passes through a fixing hole opened on the rope clamp; a fixed shaft whose position can be adjusted up and down is installed on the other side of the load-bearing sleeve, and the front end of the locking shaft is limited by the fixed shaft.

[0013] Furthermore, a shaft cylinder is assembled on the side of the load-bearing sleeve, and the fixed shaft is assembled in the shaft cylinder, and the fixed shaft can move axially in the shaft cylinder; a spring is arranged between the fixed shaft and the upper end of the shaft cylinder; a window is opened on the side wall of the shaft cylinder, and a lever passing through the window is fixed on the side wall of the fixed shaft; under the action of the spring, the fixed shaft is located in a locking position that blocks the locking shaft on its side.

[0014] Furthermore, a limiting shaft is provided on the side of the rope clamp; the limiting shaft cooperates with the fixed shaft when in the locking position.

[0015] A hoisting method is used to hoist an object according to a preset inclination angle; the method comprises:

[0016] Step 1, respectively setting fixed ends on both sides of the suspended object, and fixing the lower end of the first suspension rope and the lower end of the second suspension rope on the fixed ends on both sides respectively;

[0017] Step 2, setting the length L2 of the second lifting rope from the fixed end of the object to be lifted to the rope hole on the rope hanging plate; according to the preset inclination angle that the object to be lifted needs to reach, using geometric relationships to determine the length L1 of the first lifting rope from the fixed end on one side of the object to the fixed position of the rope clamp in the load-bearing clamp;

[0018] Step 3, fix the second hanging rope to the hanging rope hole of the hanging rope plate at a distance of L2 from the lower end thereof;

[0019] Step 4: Push the lever upward to compress the spring. After the fixed shaft is out of contact with the locking shaft, rotate the locking shaft to withdraw the rope clamp from the load-bearing clamp as a whole. Then, pass the first rope through the rope threading path on the load-bearing clamp, adjust the position of the first rope, and loosen the lever to fix the locking shaft through the fixed shaft, so that the teeth on the clamp head are engaged with the position of the first rope at a length L from the lower end thereof.

[0020] Step 5, connecting the upper end of the first lifting rope to the lifting equipment, and lifting the object through the lifting equipment; after the object leaves the ground, it will reach a preset inclination angle.

[0022] The auxiliary device provided by the present invention can quickly and conveniently adjust the inclination angle of the suspended object; the actual drop test application shows that the original situation of achieving the inclination angle of the suspended object by continuously changing the rope length is changed. This auxiliary tool is used to first lift it in a horizontal state, and then other subsequent inclination angle states can be completed at one time, avoiding the situation of repeatedly knotting the rope and trying to achieve the inclination angle of the suspended object for multiple times, and significantly improving work efficiency and accuracy.

DETAILED DESCRIPTION

[0029] See attached Figures 1 to 3 The present invention provides a convenient lifting auxiliary device, which can adjust the inclination angle of a lifted object through two lifting ropes; the device includes a load-bearing clamp 1, the cross section of the load-bearing clamp 1 is a U-shaped structure, and a rope passage 7 for passing a lifting rope is formed inside the load-bearing clamp 1; a rope clamp 11 is provided on the load-bearing clamp 1, and a clamping head 12 at the front end of the rope clamp 11 is inserted into the rope passage 7 of the load-bearing clamp 1, and teeth 8 for locking the lifting rope are provided on the clamping head 12; a rope hanging plate 16 is fixed to the rear end of the rope clamp 11, and a rope hanging hole 17 for fixing another lifting rope is opened on the rope hanging plate 16.

[0030] When the present invention is in use, firstly two lifting ropes are connected to the two sides of the suspended object respectively, and after the first lifting rope is passed through the rope threading channel 7 in the load-bearing clamping sleeve 1, the teeth 8 on the clamping head 11 at the front end of the rope clamping device 11 bite the surface of the first lifting rope, and then the rope clamping device 11 is locked and fixed. This lifting rope will also be used as a rope for lifting the suspended object, and its upper end is connected to the lifting equipment; the second lifting rope on the other side of the suspended object is fixed in the rope hanging hole 17 on the rope hanging plate 16, so that the length between this section of the lifting rope and the suspended object can be adjusted according to actual needs. After the suspended object is lifted, since the lengths of the two lifting ropes between the device and the suspended object are different, The object to be hoisted will be hoisted in an inclined posture; after hoisting, since the upper end of the first hoisting rope is connected to the hoisting equipment, and the fixing points of the first hoisting rope and the second hoisting rope and the rope clamp 11 are respectively located at the front end and the rear end of the rope clamp 11, then under the action of gravity, the load-bearing clamp 11 will be in an inclined state, which is more conducive to the rope clamp 11 to grip the first hoisting rope tightly, so that it will not slip relative to the load-bearing clamp 11; because the length of the hoisting rope can be accurately calculated before lifting, the device has a high degree of accuracy when used; this solution is simple and quick to fix the rope clamp 11, and the rope hole 17 is also very convenient for fixing the hoisting rope, so the entire hoisting process is efficient.

[0031] like Figure 1 As shown, in this embodiment, the load-bearing sleeve 1 is a U-shaped plate structure as a whole, and its internal U-shaped bending area forms the rope threading path 7.

[0032] Combination Figures 1 to 3 In this embodiment, the rope clamp 11 is a plate-like structure made of metal, and its front end is upwardly tilted to form the clamping head 12. The teeth 8 are distributed on the front end surface of the clamping head, which can generate a large friction force when it comes into contact with the lifting rope; the rear end of the rope clamp 11 is fixed with a rope hanging plate 16 by fixing bolts 15 or welding.

[0033] For the fixation of the rope clamp 11, in this solution, a clamp 14 is provided on one side of the load-bearing clamp 1, and a locking shaft 6 is installed on the clamp 14 through a sleeve 13, and the front end of the locking shaft 6 passes through the fixing hole 2 opened on the rope clamp 11; a fixed shaft 5 whose position can be adjusted up and down is installed on the other side of the load-bearing clamp 1, and the front end of the locking shaft 6 is limited by the fixed shaft 5.

[0034] Specifically, see Appendix Figure 1, a shaft cylinder 3 is installed on the side of the load-bearing sleeve 1, and the fixed shaft 5 is installed in the shaft cylinder 3, and the fixed shaft 5 can move axially in the shaft cylinder 3; a spring 4 is arranged between the fixed shaft 5 and the upper end of the shaft cylinder 3; a window is opened on the side wall of the shaft cylinder 3, and a lever 10 passing through the window is fixed on the side wall of the fixed shaft 4. The lever 10 has two functions, one is to adjust the locking rope clamp 11, and the other is to limit the position of the fixed shaft 5; under the action of the spring 4, the fixed shaft 5 is pushed to move downward until the lever 10 contacts the lower end of the window and cannot move further. At this time, the fixed shaft 5 is in the locked position, blocking the locking shaft 6 on its side, so that the position of the locking shaft 6 is fixed, thereby locking the position of the rope clamp 11, so that the rope clamp 11 can form a tight fixation of the suspension rope.

[0035] When it is necessary to remove the rope clamp 11, it is only necessary to push the lever 10 upwards to compress the spring 4. When the fixed shaft 5 reaches above the locking shaft 6, it disengages from the locking shaft 6. The locking shaft 6 can rotate using the sleeve 13 at its rear end, thereby driving the rope clamp 11 to withdraw from the load-bearing clamping sleeve 1 as a whole, and the clamping head 12 at the front end of the load-bearing clamping sleeve 1 disengages from the contact with the suspension rope.

[0036] As a further optimization of the above technical solution, a limiting shaft 9 is provided on the side of the rope clamp 11; the limiting shaft 9 cooperates with the fixed shaft 5 when it is in the locking position.

[0037] Since one of the lifting ropes is fixed to the rope hanging plate 16 at the rear end of the rope clamp 11 during the process of lifting the object, the rope clamp 11 will rotate under the action of gravity. If the rotation amplitude is too large, it may affect the engagement of the front end clamp 12 with the other lifting rope. Therefore, a limit shaft 9 is provided. When the rope clamp 11 rotates until the limit shaft 9 contacts the fixed shaft 5 in the locked position, the rope clamp 11 is restricted from continuing to rotate, so that the front end clamp 12 can effectively engage the lifting rope.

[0038] See attached Figure 4 (a) and (b) of Figure 1. When the object is hoisted horizontally, the distances from the first and second ropes to the fixed point are L1 and L2, and the angles between the first and second ropes and the surface of the object are B and C respectively. When tilted hoisting is required, the length of L2 will change. At this time, the length of L1 is calculated according to the tilt angle A required for the object to be hoisted:

[0039]

[0040] The first lifting rope here is the lifting rope that passes through the load-bearing sleeve 1 and is used for lifting, and the second lifting rope is the lifting rope fixed on the rope hanging plate 16; L1 here is the length of the first lifting rope from the fixed end on one side of the lifted object to the fixed position of the rope clamp 11 in the load-bearing sleeve 1, and L2 is the length of the second lifting rope from the fixed end on the other side of the lifted object to the rope hanging hole 17 on the rope hanging plate 16.

[0041] On the basis of the above technical solution, the present invention further provides a hoisting method for hoisting an object to be hoisted according to a preset inclination angle; the method comprises:

[0042] Step 1, respectively setting fixed ends on both sides of the suspended object, and fixing the lower end of the first suspension rope and the lower end of the second suspension rope on the fixed ends on both sides respectively;

[0043] Step 2, setting the length L2 of the second lifting rope from the fixed end of the suspended object to the rope hole 17 on the rope hanging plate 16, which should be set according to actual needs, for example, set to be greater than the length L of the suspended object; according to the preset inclination angle that the suspended object needs to reach, the length L1 of the first lifting rope from the fixed end on one side of the suspended object to the fixed position of the rope clamp 11 in the load-bearing clamp 1 is determined by using geometric relationships;

[0044] Step 3, fix the second hanging rope to the hanging rope hole 17 of the hanging rope plate 16 at a distance of L2 from the lower end thereof;

[0045] Step 4, push the lever 10 upward to compress the spring 4, and after the fixed shaft 5 is out of contact with the locking shaft 6, rotate the locking shaft 6 to make the rope clamp 11 withdraw from the load-bearing clamp 1 as a whole; then pass the first lifting rope through the rope threading path 7 on the load-bearing clamp 1, adjust the position of the first lifting rope, and release the lever 10 to fix the locking shaft 6 through the fixed shaft 5, so that the teeth 8 on the clamp head 12 are engaged with the position of the first lifting rope at a length L1 away from its lower end;

[0046] Step 5, connecting the upper end of the first lifting rope to the lifting equipment, and lifting the object through the lifting equipment; after the object leaves the ground, it will reach a preset inclination angle.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
