Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting equipment, in particular to a simple hoisting device. Background Art
[0002] To ensure reliable and horizontal lifting of a conical product, two sets of lifting straps were required, approximately 1 meter from either end of the product's center of mass. Because the product's surface was smooth and one end lacked a suitable lifting structure, conventional lifting straps could not be directly secured to that end. This necessitated the design of a convenient and reliable lifting and securing device that could securely connect the smooth conical surface of the object to the lifting straps without damaging the product's exterior. Utility Model Content
[0003] In response to the above technical problems, the utility model proposes a simple lifting device, which can rely on the weight of the hoisted object to achieve the self-tightening function of hoisting on a conical smooth surface, making the hoisting process safer and the operation more convenient.
[0004] A simple lifting device includes an upper strap, a lower strap, and a connecting piece connecting the upper strap and the lower strap. The connecting piece is provided with at least two groups. A clamping area is formed between the upper strap and the lower strap. The upper strap is used to connect the lifting equipment. After the lifting equipment lifts the lifting part, the size of the clamping area can be automatically adjusted by the weight of the lifting part and clamp the lifting part.
[0005] As a preferred embodiment of the above technical solution, the connecting member includes two positioning rods arranged in parallel, both ends of the positioning rods are positioned and locked by clamping plates, and a sleeve is movably provided on the positioning rods.
[0006] As a preferred embodiment of the above technical solution, the upper wrapping belt is movably mounted on two groups of upper positioning rods of the connecting parts at the same time, and the two ends of the lower wrapping belt are respectively connected to one group of lower positioning rods of the connecting parts.
[0007] As a preferred embodiment of the above technical solution, both the upper wrapping belt and the lower wrapping belt are flexible flat slings.
[0008] As a preferred embodiment of the above technical solution, both ends of the positioning rod are provided with threaded sections, and the clamping plate is locked by cooperating with the nut through the threaded sections.
[0009] As a preferred embodiment of the above technical solution, the upper and lower wrapping straps are both 10 cm wide flexible flat slings.
[0010] The beneficial effects of the present invention are:
[0011] This lifting fixture quickly and easily achieves horizontal clamping of product exteriors without damaging the product's appearance. During product lifting, the product's own weight secures the structure, preventing axial movement and improving lifting safety. By adjusting the strap length, the lifting fixture can horizontally lift products of varying sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The reference numerals are as follows: 1-upper wrapping tape, 2-lower wrapping tape, 3-connecting piece, 4-clamping area, 5-positioning rod, 6-clamping plate, 7-sleeve, 8-threaded segment, 9-nut. DETAILED DESCRIPTION
[0015] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0016] like Figure 1 、 Figure 2 The simple lifting device includes an upper strap 1, a lower strap 2 and a connecting piece 3 connecting the upper strap 1 and the lower strap 2. The connecting piece 3 is provided with at least two groups. A clamping area 4 is formed between the upper strap 1 and the lower strap 2. The upper strap 1 is used to connect the lifting equipment. After the lifting equipment lifts the lifting part, the size of the clamping area 4 can be automatically adjusted by the weight of the lifting part and clamp the lifting part.
[0017] In this embodiment, the connecting member 3 includes two positioning rods 5 arranged in parallel. Both ends of the positioning rods 5 are positioned and locked by clamping plates 6. A sleeve 7 is movably sleeved on the positioning rods 6.
[0018] In this embodiment, the upper wrapping belt 1 is movably mounted on two groups of upper positioning rods 5 of the connecting members 3 at the same time, and both ends of the lower wrapping belt 2 are respectively connected to one group of lower positioning rods 5 of the connecting members 3 .
[0019] In this embodiment, the upper strap 1 and the lower strap 2 are both flexible flat slings.
[0020] In this embodiment, threaded sections 8 are provided at both ends of the positioning rod 5 , and the clamping plate 6 is locked by the threaded sections 8 and the nuts 9 .
[0021] In this embodiment, the upper strap 1 and the lower strap 2 are both flexible flat slings with a width of 10 cm.
[0022] In this embodiment, the upper wrapping belt 1 and the lower wrapping belt 2 are both 10 cm wide flexible flat slings, and the appropriate specifications and lengths are selected according to the product's external dimensions to circumferentially wrap the outer surface of the product during the lifting process.
[0023] The lower sleeves 7 of the two connecting pieces 3 are connected to the two lifting holes of the lower wrapping belt 2, respectively. The upper wrapping belt 2 is passed through the gap between the upper and lower sleeves 7 of the two connecting pieces 3. During use, the product passes through the clamping area 4 from the small end of the conical section. When lifting, the upper wrapping belt 2 generates a large downward pressure on the product surface due to the weight of the product. This pressure makes the upper and lower wrapping belts 1 and 2 fit tightly to the outer contour of the product. The axial static friction formed between the upper and lower wrapping belts 1 and 2 and the product prevents forward and backward movement between the upper and lower wrapping belts and the product, forming a self-tightening structure.
[0024] This simple lifting fixture is designed for products without a lifting structure on one end. It allows for quick and convenient horizontal clamping of the product's exterior without damaging its appearance. During lifting, the product's own weight secures the lifting structure, preventing axial movement and improving lifting safety. By adjusting the strap length, the lifting fixture can horizontally lift products of varying sizes.
[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
