Description

Technical Field

[0001] The utility model relates to the field of position limiting and fixing devices, in particular to a position limiting and fixing device which can be flexibly adjusted for loading and unloading large objects. Background Art

[0002] The limit fixing device for loading and unloading large objects is an important safety device used to ensure stability and safety during the loading and unloading process. They can limit the movement range of large objects during loading and unloading to prevent accidents, and the adjustment function can increase the flexibility of use.

[0003] In the prior art, when large objects are generally loaded, unloaded, and hoisted, they are generally positioned by dedicated limit fixing devices. However, general limit fixing devices are dedicated, and the size adjustment function can only be adjusted in a small range to fix specific objects. When the sizes of the objects vary greatly, it is necessary to select a limit fixing device of appropriate size. One fixing device cannot be applied to objects of different sizes, and the application surface is narrow. Frequent replacement operations are cumbersome. Therefore, it is necessary to improve a limit fixing device for loading and unloading large objects that can be flexibly adjusted to solve the above problems. Utility Model Content

[0006] Preferably, the position of the positioning frame is adjusted by pushing the first slider through the electric push rod, so that the positioning frame fits against the object, and at the same time, the second slider is driven by the rotation of the bidirectional screw to adjust the position of the clamping plate, so that the clamping plate clamps the object, so that the object can be positioned synchronously from four directions, and the position of the object can be stably fixed. The first bolt fixes the position of the sliding plate after adjustment, and then it is connected to the loading and unloading place through the fixing ear to fix the position.

[0007] Preferably, the limiting frame has a slide groove at the corresponding position of the first slider, and the first slider slides inside the slide groove. The first slider is limited by the slide groove, so that the electric push rod pushes the first slider of the plate to be guided and limited by the slide groove to prevent tilting and deviation.

[0008] Preferably, the positioning frame has a sliding groove at the corresponding position of the second slider, and the second slider slides inside the sliding groove. The sliding groove limits and guides the second slider to prevent the bidirectional screw from rotating when driving the second slider to move, so that it can only slide in a straight line.

[0009] Preferably, the positioning frame and the first slider are internally rotatably connected with a limit plate, the outer side of the limit plate is fixedly connected with an external hexagonal rotating block, the inner side of the limit plate is fixedly connected with a bidirectional screw, the second slider is threadedly connected to the outside of the bidirectional screw, the inner side of the second slider is fixedly connected with a splint, the inner side of the splint is fixedly connected with a rubber pad, and the electric push rod and the bidirectional screw are adjusted to a suitable position, and can be flexibly adjusted according to the size of the object, with a wider range of applications.

[0010] Preferably, the fixing mechanism includes a slide plate, which is slidably connected to the inside of the limit frame, the internal thread of the slide plate is connected to a first bolt, the first bolt is clamped in the inside of the limit frame, the outer side of the slide plate is fixedly connected to a fixing ear, the inside of the fixing ear is movably connected to a second bolt, the external thread of the second bolt is connected to a nut, and the position of the fixing ear is adjusted by the slide plate so that the device can be fixed in a suitable position, thereby positioning the object for loading and unloading.

[0011] Preferably, the limiting frame has a clamping hole at the corresponding position of the first bolt, and the first bolt is clamped in the clamping hole. The position of the slide can be located by clamping the first bolt in the clamping hole, and the position of the slide can be stably fixed after adjustment.

[0012] Preferably, the limiting frame is provided with a slide groove at a corresponding position of the slide plate, and the slide plate slides inside the slide groove, and the slide plate is limited by the slide groove so that the slide plate will not leave the slide groove of the limiting frame, thereby conveniently adjusting the slide plate.

[0013] Beneficial effects of the utility model:

[0014] 1. The position of the positioning frame is adjusted by the electric push rod, so that the positioning frames on both sides move synchronously. The clamping plates are driven to move synchronously by the bidirectional screw to clamp the objects.
