Description

Technical Field

[0001] The utility model relates to the technical field of lifting machinery, in particular to an electric hoist vertical lift. Background Art

[0002] Hoists are electromechanical devices used for vertical lifting, or vertical lifting and horizontal movement of heavy objects. Lifting is an industrial process that transports machinery or other objects from one location to another. Most hoists begin their vertical or combined vertical and horizontal travel after the spreader retrieves material. Upon reaching the destination, they unload and then travel back to the retrieval location, completing a cycle.

[0003] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.

[0004] Electric hoists are used in the crane industry and typically need to move on rails. However, electric hoists typically lift workpieces using chains. However, when the hoist is moving on rails, the workpiece can easily swing due to braking or inertia, resulting in unstable transportation and easily breaking the chain, causing the object to fall from a height. Utility Model Content

[0005] The purpose of the utility model is to provide an electric hoist vertical lift to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: an electric hoist vertical lifter, comprising a pipe sleeve and a main pipe, the main pipe passing through the pipe sleeve, a slewing assembly provided at the top of the pipe sleeve, a support platform provided on the outside of the slewing assembly, the slewing assembly comprising an outer ring support and an inner ring support rotatably connected to the inner side of the outer ring support, the pipe sleeve being connected to the inner ring support, the support platform being connected to the outer ring support, a lifting lug seat being fixed at the end of the main pipe, a flange assembly being provided below the lifting lug seat, and the slewing assembly being capable of ensuring that the workpiece can rotate 360° during the lifting process;

[0007] A first mounting plate and a second mounting plate are provided on the side of the pipe sleeve. The electric hoist body is provided on the first mounting plate. The chain provided on the electric hoist body is connected to the lifting lug seat. The anti-fall speed differential is provided on the second mounting plate. The steel cable provided on the anti-fall speed differential is connected to the lifting lug seat. The electric hoist body is used for lifting operations of workpieces, and the anti-fall speed differential plays a role in preventing falling.

[0008] There are multiple through grooves on the outer wall of the pipe sleeve, and a mounting seat is provided at the through groove. The mounting seat is rotatably connected to a guide wheel, which fits the main pipe and is used for guiding and centering when the main pipe slides up and down.

[0009] The lifting pipe is made of aluminum. The hoist's main body is driven by the chain, which moves the pipe up and down inside the pipe sleeve to lift the workpiece. If the hoist chain fails, the anti-fall speed differential can buffer the workpiece's falling speed and prevent it from falling.

[0010] Preferably, a limit plate is provided on the top of the main pipe, which is connected to the main pipe by bolts. The limit plate is mainly used to prevent the main pipe from sliding out of the pipe sleeve.

[0011] Preferably, the pipe sleeve is a square structure, and the main pipe adopts a square pipe adapted to the pipe sleeve to prevent the main pipe from rotating in the pipe sleeve.

[0012] Preferably, the flange assembly includes an upper flange and a lower flange installed below the upper flange, the upper flange is connected to the lifting lug seat, and the lower flange is used to connect the lifting workpiece.

[0013] Preferably, the mounting seat is made of metal material and the guide wheel is made of wear-resistant nylon material to improve the wear resistance.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This utility model connects the inner ring of the slewing assembly to the pipe sleeve, which is then connected to the lifting lug seat via the chain of the electric hoist body and the steel cable of the anti-fall speed differential. This allows the workpiece to rotate 360° during ascent and descent. The design of the pipe sleeve and main pipe prevents workpiece shaking and improves stability. Furthermore, if the hoist chain fails, the anti-fall speed differential can buffer the workpiece's falling speed and prevent it from falling, thus enhancing the safety of the device.

[0024] See also Figure 1-4 The utility model provides a technical solution: an electric hoist vertical lifter, comprising a pipe sleeve 1 and a main pipe 2, the main pipe 2 passing through the pipe sleeve 1, a slewing assembly 3 is provided at the top of the pipe sleeve 1, a supporting platform 4 is provided on the outside of the slewing assembly 3, the slewing assembly 3 comprises an outer ring support 301 and an inner ring support 302 rotatably connected to the inner side of the outer ring support 301, the pipe sleeve 1 is connected to the inner ring support 302, the supporting platform 4 is connected to the outer ring support 301, a lifting ear seat 5 is fixed at the end of the main pipe 2, a flange assembly 8 is provided below the lifting ear seat 5, and the slewing assembly 3 can ensure that the workpiece can rotate 360 degrees during the lifting process;

[0025] A first mounting plate 101 and a second mounting plate 102 are provided on the side of the pipe sleeve 1. The electric hoist body 6 is provided on the first mounting plate 101. The chain provided on the electric hoist body 6 is connected to the lifting lug seat 5. The anti-fall speed differential device 7 is provided on the second mounting plate 102. The steel cable provided on the anti-fall speed differential device 7 is connected to the lifting lug seat 5. The electric hoist body 6 is used for lifting operations of workpieces, and the anti-fall speed differential device 7 plays a role in preventing falling.

[0026] A plurality of through grooves are provided on the outer wall of the pipe sleeve 1, and a mounting seat 9 is provided at the through groove. A guide wheel 901 is rotatably connected to the mounting seat 9, and the guide wheel 901 is in contact with the main pipe 2. The guide wheel 901 is used for guiding and centering when the main pipe 2 slides up and down.

[0027] The electric hoist body 6 and the anti-fall speed differential 7 are existing well-known technologies and can be purchased on the market, so they will not be described in detail here.

[0028] The lifting pipe 2 is made of aluminum profile. The electric hoist body 6 drives the pipe 2 to slide up and down inside the pipe sleeve 1 to lift the workpiece through the rise and fall of the chain. When the electric hoist chain fails, the anti-fall speed differential 7 can buffer the falling speed of the workpiece and prevent it from falling.

[0029] Furthermore, a limit plate 10 is provided at the top of the main pipe 2 , and the limit plate 10 is connected to the main pipe 2 by bolts. The limit plate 10 mainly prevents the main pipe 2 from sliding out of the pipe sleeve 1 .

[0030] Furthermore, the pipe sleeve 1 is a square structure, and the main pipe 2 is a square pipe adapted to the pipe sleeve 1 to prevent the main pipe 2 from rotating in the pipe sleeve 1 .

[0031] Furthermore, the flange assembly 8 includes an upper flange 801 and a lower flange 802 installed below the upper flange 801. The upper flange 801 is connected to the lifting lug seat 5, and the lower flange 802 is used to connect the lifting workpiece.

[0032] Furthermore, the mounting seat 9 is made of metal material, and the guide wheel 901 is made of wear-resistant nylon material to improve the wear resistance.

[0033] In summary, when the device is in use, the workpiece is mounted on the lower flange 802, and then the electric hoist body 6 is controlled to reel in or lower the chain, so that the chain pulls the lifting lug seat 5 to slide up and down inside the pipe sleeve 1 to lift the workpiece, thereby achieving the lifting of the workpiece.

[0034] During the process, the design of the pipe sleeve 1 and the main pipe 2 can achieve vertical lifting, allowing the workpiece to be rigidly connected to the vertical lift through the flange, thus offsetting the swing inertia of the workpiece and ensuring the smooth transportation of the workpiece. In addition, when the main pipe slides up and down, the guide wheel rolls on the main pipe, playing a guiding and centering role.

[0035] Because the pipe sleeve 1 is mounted on the inner support 302 of the slewing assembly 3, the workpiece can rotate 360 degrees during the lifting process, while simultaneously driving the electric hoist body 6 to rotate, preventing chain breakage. Furthermore, if the chain of the electric hoist body 6 fails during the lifting process, the anti-fall speed differential 7 can buffer the falling speed of the workpiece and prevent it from falling.

[0036] It is worth noting that the entire device is controlled by a master control button. Since the devices matched with the control button are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
