Description

Technical Field

[0001] This utility model relates to the field of crane hoisting and positioning technology, specifically to an automatic positioning and hoisting device for cranes. Background Technology

[0002] In the loading and unloading of warehousing equipment and materials, hoisting operations are an important part of the warehousing process, especially when using bridge cranes to hoist large equipment.

[0003] Application number CN202321346137.3 discloses a laser positioning device for crane lifting, including support rods, a fixed base, a laser head, a level, and an adjustment and installation assembly. The outer wall of the fixed base has three support rods, one end of which is connected to the fixed base, and the other end is equipped with the adjustment and installation assembly. A level is mounted on the top of the fixed base. The laser head is mounted on the fixed base and can emit a laser beam towards the ground. The adjustment and installation assembly includes a screw, and the support rods are adjustablely mounted on the screw. By illuminating the ground or the equipment to be lifted with the laser head, the device assists in determining the position of the hook, increasing the speed of lifting goods, reducing the risk of lifting goods, and effectively improving the warehouse goods handling process.

[0004] However, the above-mentioned equipment still has some problems in use: the equipment uses set bolts to hold the laser head in place, but because the outer surface of the laser head is round, the fixation is not stable enough. In addition, the equipment is fixed to the hook by magnetic attraction, and since hoisting is a high-altitude operation, the equipment is prone to falling from a height. Utility Model Content

[0005] To address the issues raised by the aforementioned devices, which use set bolts to hold the laser head in place, but whose outer surface is circular, resulting in unstable fixation, and the problem of the device easily falling from heights when secured to the hook using magnets (as this involves high-altitude operations), this invention aims to provide an automatic positioning and hoisting device for cranes.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: an automatic positioning and hoisting device for a crane, including a hook and a fixing plate, and a laser light. A stable positioning component is connected to the hook and the fixing plate. An installation cylinder is fixedly provided inside the fixing plate. A connection hole is opened on the lower surface of the installation cylinder. The laser light is movably inserted into the connection hole. An assembly limiting component is fixedly provided on the lower surface of the installation cylinder.

[0007] The assembly limiting component includes a fixed shell, which is fixedly connected to the lower surface of the mounting cylinder. A spring is fixedly installed inside the fixed shell, and a slider is fixedly installed at the other end of the spring. There are four springs, which are symmetrically arranged between the fixed shell and the slider. The slider slides against the inner surface of the fixed shell. A limiting plate is fixedly installed on the side of the slider away from the spring. The limiting plate moves through the fixed shell and moves against the lower surface of the laser lamp. A through groove is opened on the lower surface of the fixed shell, and a pull block slides in the through groove. The pull block is fixedly connected to the slider.

[0008] Preferably, the stable positioning component includes a positioning block, which is fixedly connected to one side of the fixed plate. A positioning plate is welded to the outer surface of the hook. A positioning groove is provided inside the positioning plate. The positioning block is movably fitted with the inner surface of the positioning groove. Both the positioning plate and the positioning block have through holes. A bolt is movably inserted into the through hole. A nut is threaded onto the outer surface of the bolt.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model uses a laser light to illuminate the ground or the equipment to be hoisted to help determine the position of the hook, thereby increasing the speed of hoisting goods. When installing the laser light, the pull block can be pulled to move the slider and retract the limiting plate into the fixed shell. Then the laser light can be inserted into the connection hole. After releasing the pull block, the limiting plate can be moved to the center by the force of the spring. The limiting plate blocks the laser light, thereby preventing the laser light from falling from a height.

[0011] 2. This utility model improves the stability of the assembly by welding the positioning block to the hook, then placing the positioning block on one side of the fixing plate into the positioning groove, then inserting bolts into the through holes corresponding to the positioning block on the positioning plate, and finally assembling with nuts.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides an automatic positioning and hoisting device for a crane, including a hook 1, a fixing plate 2, and a laser light 3. A stable positioning component 5 is connected to the hook 1 and the fixing plate 2. An installation cylinder 21 is fixedly provided inside the fixing plate 2. A connection hole 22 is opened on the lower surface of the installation cylinder 21. The laser light 3 is movably inserted into the connection hole 22. An assembly limiting component 4 is fixedly provided on the lower surface of the installation cylinder 21.

[0020] The assembly limiting component 4 includes a fixed shell 41, which is fixedly connected to the lower surface of the mounting cylinder 21. A spring 42 is fixedly installed inside the fixed shell 41, and a slider 43 is fixedly installed at the other end of the spring 42. The slider 43 slides against the inner surface of the fixed shell 41. A limiting plate 44 is fixedly installed on the side of the slider 43 away from the spring 42. The limiting plate 44 movably passes through the fixed shell 41 and movably fits against the lower surface of the laser lamp 3. A through groove 45 is formed on the lower surface of the fixed shell 41. The inner sliding block 46 is fixedly connected to the slider 43. The position of the hook 1 is assisted by the laser light 3 shining on the ground or the equipment to be hoisted, thereby improving the speed of hoisting goods. When installing the laser light 3, the pull block 46 can be pulled to move the slider 43 and retract the limiting plate 44 into the fixed shell 41. Then the laser light 3 can be inserted into the connecting hole 22. After releasing the pull block 46, the limiting plate 44 can be moved to the center by the force of the spring 42. The limiting plate 44 blocks the laser light 3, thereby preventing the laser light 3 from falling from a height.

[0021] Four springs 42 are provided and symmetrically arranged between the fixed shell 41 and the slider 43. The multiple springs 42 can improve the stability of the connection. The cross-sectional shape of the pull block 46 is "T" shaped, which facilitates the connection of the slider 43 and also facilitates the movement of the pull block 46. Two fixed shells 41 are provided and symmetrically arranged on the lower surface of the mounting cylinder 21 to improve the stability when the limit is reached.

[0022] The stable positioning component 5 includes a positioning block 51, which is fixedly connected to one side of the fixing plate 2. Four through holes 53 are provided, with two symmetrically arranged on both the positioning block 51 and the positioning plate 52 to improve assembly stability. A positioning plate 52 is welded to the outer surface of the hook 1. A positioning groove 521 is formed inside the positioning plate 52, and the positioning block 51 is movably fitted to the inner surface of the positioning groove 521. Both the positioning plate 52 and the positioning block 51 have through holes 53, and bolts 54 are movably inserted into the through holes 53. Nuts 55 are threaded onto the outer surface of the bolts 54. The cross-sectional shape of both the positioning block 51 and the positioning plate 52 is concave. By welding the positioning block 51 to the hook 1, the positioning block 51 on one side of the fixing plate 2 can be placed into the positioning groove 521. Then, the bolts 54 can be inserted into the corresponding through holes 53 of the positioning plate 52 and the positioning block 51, and finally, the assembly can be completed by using the nuts 55, thus improving the stability after assembly.

[0023] Working principle: This utility model uses the laser light 3 to illuminate the ground or the equipment to be hoisted to assist in judging the position of the hook 1, thereby improving the speed of hoisting goods. When installing the laser light 3, the pull block 46 can be pulled to move the slider 43, and the limiting plate 44 can be retracted into the fixed shell 41. Then the laser light 3 can be inserted into the connecting hole 22. After releasing the pull block 46, the limiting plate 44 can be moved to the center by the force of the spring 42. The limiting plate 44 blocks the laser light 3, thereby preventing the laser light 3 from falling from a height.

[0024] By welding the positioning block 51 onto the hook 1, the positioning block 51 on one side of the fixing plate 2 can be placed into the positioning groove 521. Then, the bolt 54 can be inserted into the through hole 53 corresponding to the positioning block 51 in the positioning plate 52, and then assembled by using the nut 55, thereby improving the stability after assembly.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
