Description

Technical Field

[0001] This utility model relates to the field of vertical hoisting technology, specifically a vertical hoisting device for hoisting motors. Background Technology

[0002] The service life of an electric motor is closely related to its working environment, operating time, working condition, and lubrication status. In the early stages of a factory's construction, motors operated well, and the probability of replacement after damage was low, so the inconvenience of motor replacement was not obvious. However, the hot rolling mill has been in operation for over 16 years, and due to the combination of the aforementioned factors, the motors have gradually begun to exhibit abnormal noise, excessive vibration, and even burnout. The problem of inconvenient replacement of underground motors is now particularly prominent.

[0003] In the past, motors were mostly transported horizontally using a combination of hooks and lifting lugs. However, in actual replacement processes, even small motors in the lubrication station face the problem of insufficient hoisting space, making horizontal hoisting impassable. Currently, motors in the underground main motor lubrication station of the hot rolling area can only be carried manually over long distances to large hoisting openings or lifted to the ground by hand. Manual handling is risky, especially when going up and down stairs. With workers moving up and down, slipping and falling can easily lead to accidents. Therefore, adding hoisting openings in various areas is essential. However, to ensure the stability of the building, the area of ​​the new hoisting openings must be as small as possible. This makes the advantages of vertical hoisting of motors even more prominent.

[0004] Furthermore, the complex piping of the underground hydraulic station's lubrication system makes motor reversal extremely inconvenient, and there are issues with insufficient space for horizontal hoisting and passage. After this invention is implemented, combined with the later addition of slide rails and hoisting holes to the underground hydraulic station, it can solve more than 90% of the motor reversal problems. Utility Model Content

[0005] The purpose of this invention is to provide a vertical lifting device for hoisting motors, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical lifting device for hoisting motors, comprising a lifting ring and an upper sliding cylinder fixedly connected to its bottom, and further comprising: The lifting device body is slidably connected to the surface of the upper sliding cylinder. The bottom surface of the upper sliding cylinder is provided with a sliding column. The inner wall of the lifting device body is provided with a track groove. A clamping mechanism is installed inside the lifting device body. Vertical fasteners are fixedly connected to the surface of the upper slide cylinder; anti-bending fasteners are fixedly connected to the surface of the main body of the lifting device; horizontal fasteners are fixedly connected to the surface of the main body of the lifting device; and an anti-loosening mechanism is installed on the surface of the main body of the lifting device.

[0007] Preferably, the clamping mechanism includes a smooth cylinder slidably connected to the inner cavity of the lifting device body, a replaceable gripper fixedly connected to the surface of the smooth cylinder, a locking mechanism provided inside the replaceable gripper, a rotating base fixedly connected to the top of one end of the replaceable gripper, and a rotating rod slidably connected to the inner cavity of the rotating base.

[0008] Preferably, the locking mechanism includes a first threaded groove formed at one end of the smooth cylinder, and a second threaded groove is formed inside the replaceable gripper, with a threaded rod threadedly connected to the surface of the second threaded groove.

[0009] Preferably, the anti-loosening mechanism includes a friction slider slidably connected to the inner wall of the lifting device body, a threaded sleeve fixedly connected to the surface of the lifting device body, and a nut connected to the threaded sleeve.

[0010] Preferably, the threads of the first and second threaded grooves match the threads on the surface of the threaded rod, and the strength of the threaded rod meets the strength required by the weight of the hoisting motor.

[0011] Preferably, the bottom of the friction slider is provided with concave and convex wear-resistant textures, the bottom of the inner cavity of the threaded sleeve is a smooth inner wall and its upper surface is provided with threads, and the bottom of the nut is a circular plate design.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model restricts the transportation conditions of the device through the sliding design of the upper sliding cylinder and the main body of the lifting device. This design effectively reduces the size of the opening in the ground, ensures the stability of the building, and avoids the need to manually move the motor, thus effectively improving the safety during transportation. The clamping mechanism is designed to automatically lock the motor in place using its own weight during hoisting, eliminating the need for external clamping devices and making the device more compact. In addition, the anti-loosening mechanism provides secondary anti-loosening protection for the motor, preventing the primary anti-loosening mechanism from failing due to external factors, which could cause the motor to fall and injure workers.

[0013] This solves the problem of insufficient safety when transporting motors in existing devices, which also affects the stability of buildings. Attached Figure Description

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figure 1-5 As shown, a vertical lifting device for hoisting motors includes a lifting ring 1, which is a circular ring structure used to hoist the entire device. An upper sliding cylinder 2 is fixedly connected to the bottom of the lifting ring 1, and the lifting device body 3 is slidably connected to the surface of the upper sliding cylinder 2.

[0018] It should be noted that the interior of the upper slide cylinder 2 is hollow to allow space for the motor output shaft, making the structure more compact.

[0019] The bottom surface of the upper sliding cylinder 2 is provided with sliding columns 4, and there are several sliding columns 4. The inner wall of the lifting device body 3 is provided with track grooves 5, and the number of track grooves 5 is equal to the number of sliding columns 4, so as to guide the up and down sliding of the lifting device body 3.

[0020] It should be noted that the length of the sliding column 4 is less than the height of the track groove 5, which is used to limit the main body 3 of the lifting device and prevent the main body 3 of the lifting device from sliding off the surface of the upper sliding cylinder 2.

[0021] The lifting device body 3 is equipped with a clamping mechanism 6. The clamping mechanism 6 includes a smooth cylinder 61 that is slidably connected to the inner cavity of the lifting device body 3. A replaceable gripper 62 is fixedly connected to the surface of the smooth cylinder 61. There are two smooth cylinders 61. A locking mechanism 63 is provided inside the replaceable gripper 62.

[0022] It should be noted that the bottom of the replaceable gripper 62 is a thickened base plate with internal vertical ribs to prevent bending and horizontal displacement. The replaceable gripper 62 can be modified to different sizes according to the weight of the hoisting motor and the limitations of the material. The gripper head of the replaceable gripper 62 can be made into two, three, or four claws according to the strength requirements.

[0023] The locking mechanism 63 includes a first threaded groove 631 opened at one end of the smooth cylinder 61, and a second threaded groove 632 opened inside the replaceable gripper 62. A threaded rod 633 is threadedly connected to the surface of the second threaded groove 632, which is used to lock the replaceable gripper 62 and the smooth cylinder 61.

[0024] It should be noted that the threads of the first threaded groove 631 and the second threaded groove 632 are matched with the threads on the surface of the threaded rod 633, and the threaded rod 633 meets the strength requirements brought about by the gravity of the hoisting motor.

[0025] Based on the above implementation scheme, the clamping mechanism 6 also includes a rotating base 64 fixedly connected to the top of one end of the replaceable gripper 62. There are several rotating bases 64, and two rotating rods 65 are slidably connected to the inner cavity of the rotating base 64.

[0026] It should be noted that the rotating base 64 is fixedly connected to the upper surface of the upper sliding cylinder 2 and the top of one end of the smooth cylinder 61.

[0027] This setup is used to automatically clamp the hoisted motor. When the motor is mounted on the surface of the replaceable gripper 62, the weight of the motor causes the main body 3 of the lifting device to slide downwards, while the rotating rod 65 swings inwards, thereby causing the smooth cylinder 61 to slide inwards along the inner cavity of the main body 3 of the lifting device, thus achieving automatic clamping and first-level anti-loosening measures.

[0028] Vertical fasteners 7 are fixedly connected to the surface of the upper sliding cylinder 2. There are several vertical fasteners 7, which are used to reinforce the rotating base 64 and its connecting parts.

[0029] Two anti-bending fasteners 8 are fixedly connected to the surface of the main body 3 of the lifting device. Several transverse fasteners 9 are also fixedly connected to the surface of the main body 3 of the lifting device. By cooperating with the anti-bending fasteners 8 and the transverse fasteners 9, the strength at the bend of the main body 3 of the lifting device can be improved, and the deformation of the main body 3 of the lifting device due to excessive motor weight can be prevented from affecting the function of the device.

[0030] The surface of the lifting device body 3 is equipped with an anti-loosening mechanism 10, which is used to perform secondary anti-loosening on the smooth cylinder 61 to prevent the motor from falling off due to failure of the primary anti-loosening mechanism after collision or bottoming out during the lifting process.

[0031] The anti-loosening mechanism 10 includes a friction slider 101 slidably connected to the inner wall of the lifting body 3. A threaded sleeve 102 is fixedly connected to the surface of the lifting body 3. The friction slider 101 is slidably connected to the inner cavity of the threaded sleeve 102. A nut 103 is threadedly connected to the inner cavity of the threaded sleeve 102. By tightening the nut 103, the bottom of the friction slider 101 rubs against the smooth cylinder 61, thereby achieving secondary loosening and preventing the smooth cylinder 61 from moving during lifting.

[0032] It should be noted that the bottom of the friction slider 101 is provided with concave and convex wear-resistant textures to improve the friction between the friction slider 101 and the smooth cylinder 61. The bottom of the inner cavity of the threaded sleeve 102 is a smooth inner wall, and its top is provided with threads. The bottom of the nut 103 is designed as a circular plate to increase the contact area between the nut 103 and the friction slider 101, thereby making it easier to push the friction slider 101. The circular plate is rotatably connected to the top of the friction slider 101.

[0033] It is worth noting that the technical features such as the lifting ring 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0034] Working principle: First, select the size and shape of the replaceable gripper 62, i.e., the number of grippers, based on the weight and material of the motor. Then, install the device on the winch. Next, install the motor on the surface of the replaceable gripper 62. Subsequently, the electric winch drives the device to move upward. Under the action of the motor's gravity, the lifting device body 3 slides downward along the surface of the upper sliding cylinder 2. As the lifting device body 3 slides downward, the rotating rod 65 begins to swing inward, and carries the rotating base 64 to slide inward along the inner cavity of the lifting device body 3. During this process, the motor is vibrated and clamped, and the motor's own weight achieves the first-level anti-loosening. Then, the winch continues to rise. When the motor leaves the ground, the smoothing cylinder 61 moves to its limit position. The operator tightens the nut 103, causing the bottom surface of the friction slider 101 to rub against the surface of the smoothing cylinder 61, thereby achieving the second-level anti-loosening. This prevents the smoothing cylinder 61 from shifting due to the failure of the first-level anti-loosening during the rising process. Finally, the winch transports the motor from the underground main motor lubrication station in the hot rolling area to the ground, completing the lifting operation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
