Description

Technical Field

[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a box hoisting fixture. Background Art

[0002] PACK box refers to a foldable container with a special design, also known as a foldable container. It has similar functions to traditional containers and can be used for the transportation and storage of goods, but its characteristic is that it can be folded when not in use, thus saving space and transportation costs. PACK boxes are usually made of lightweight but strong materials, such as plastic or aluminum alloy, and have high load-bearing capacity and waterproof performance. They are widely used in the logistics industry, especially in scenarios where frequent loading and unloading of goods or limited space are required, such as air cargo, shipping, warehousing, etc.

[0003] In industry, PACK boxes have built-in weighing components, and the weight of the entire box is more than 50 kg. Because the outside of the box is smooth, it is difficult to grasp and carry, especially when it is carried to a high place and stacked, half of it will be stacked 7-10 layers. The higher the stack, the more difficult it is to grasp, the longer it takes, the more effort it consumes, and it is not convenient to operate when taking it down. Summary of the invention

[0004] The utility model aims to provide a box hoisting fixture to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a box lifting clamp, used for clamping a lifting box, including a hanging seat, a slide rail arranged parallel to the length direction of the hanging seat is provided below the hanging seat, two clamping blocks with openings arranged opposite to each other are provided below the slide rail, a slider is provided on the top of each clamping block, each clamping block is slidably matched with the slide rail through the slider, and a positioning assembly is provided between each clamping block and the hanging seat; the positioning assembly can complete the clamping and positioning of boxes of different specifications through the cooperation of pin holes, which is convenient for operation.

[0006] The clamping block includes a U-shaped holding part, which includes an upper clamping surface and a lower clamping surface, and a side clamping surface is provided between the upper clamping surface and the lower clamping surface. The two clamping blocks are moved toward each other, and the upper clamping surface, the lower clamping surface and the side clamping surface on the clamping block clamp the box body. The upper clamping surface is provided with a first positioning step and a second positioning step, and the first positioning step and the second positioning step form a contact surface with the top of the box body. The U-shaped holding part tightly clamps the top surface, the side surface and the bottom surface of the box body, and the clamping force is balanced and stable, and the surface force is achieved. After clamping, it will not slip and overturn, and it can be smoothly transferred in both vertical and horizontal hoisting directions. The box body itself will not be squeezed and deformed due to its own excessive weight.

[0007] As a further solution of the utility model, the positioning assembly includes a row of evenly distributed positioning holes penetrating the slide rail and the hanging seat, a locking hole that can be aligned with each positioning hole is provided on the first positioning step, a positioning pin is provided in the positioning hole, the locking hole is aligned with one of the positioning holes, and the positioning pin passes through the positioning hole and is inserted into the locking hole for positioning. The positioning pin and the positioning hole cooperate to facilitate loading and unloading, quickly position, and improve the lifting efficiency.

[0008] As a further solution of the utility model, the first positioning step and the second positioning step are both made of rubber to buffer the clamping force on the clamping contact surface. During the clamping process, the rubber clamping contact surface avoids the box body from being squeezed and deformed and unevenly stressed due to dimensional deviation and external force.

[0009] As a further solution of the utility model, the hanging seat includes a horizontal seat, the bottom of the horizontal seat is fixedly arranged with the slide rail, the top of the horizontal seat is provided with a vertical plate along the central axis, the vertical plate is symmetrically provided with two hanging holes along the length direction, and the hanging holes are provided with a hanging rope for upward pulling. The hanging rope can transmit external tension to the hanging seat, and the vertical plate not only strengthens the strength and force of the horizontal seat, but also provides a base for hanging force, so that the hanging is safe and the weighing is good.

[0010] As a further solution of the utility model, there are two slide rails, which are symmetrically arranged on both sides of the length direction of the horizontal seat, and each clamping block is stacked with two sliders, each slider slidingly cooperates with the slide rail on the corresponding side. The two slide rails are stressed at the same time and evenly, and when hoisting a relatively heavy box, it is not easy to cause the slider and the slide rail to deform due to stress.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The clamping block includes a U-shaped support part, which tightly clamps the top, side and bottom surfaces of the box. The clamping force is balanced and stable, and the surface force is achieved. After clamping, it will not slip and tip over. It can be smoothly transferred in both vertical and horizontal directions. The box itself will not be squeezed and deformed due to its own excessive weight.

[0013] (2) The first and second positioning steps on the U-shaped support part are made of rubber to buffer the clamping force on the clamping contact surface. During the clamping process, the rubber clamping contact surface prevents the box from being squeezed and deformed and unevenly stressed due to dimensional deviation and external force.

[0014] (3) The positioning assembly can complete the clamping and positioning of boxes of different specifications through the cooperation of positioning pins and positioning holes. It is easy to load and unload, quickly position, and convenient to operate, thus improving the lifting efficiency.

[0015] (4) The hanging seat includes a horizontal seat, the bottom of which is fixed to the slide rail, and a vertical plate is provided on the top of the horizontal seat along the central axis. The hoisting rope can transmit external tension to the hanging seat. The vertical plate not only strengthens the strength and force of the horizontal seat, but also provides a base for hoisting force, which is safe for hoisting and good for weighing. In addition, the two slide rails are stressed at the same time and evenly. When hoisting a heavier box, it is not easy to cause deformation of the slider and the slide rail.
