Abstract
Description
Technical Field
[0001] This utility model relates to the field of manual turning technology, specifically a manual turning mechanism with a limit function. Background Technology
[0002] After equipment installation or maintenance, the rotating parts of the equipment can be rotated by manually turning the turning mechanism, which makes it easy for staff to check whether there are any parts that are not installed properly or misaligned. For example, after the maintenance of a large motor, the motor rotor can be rotated by manually turning the turning mechanism to check whether there are any friction marks between the stator and the rotor, and to ensure that the installation gaps of the internal components of the motor are normal.
[0003] The existing turning gear mechanism has the following defects during use:
[0004] 1. In the maintenance of equipment in some old factories, manual turning can be implemented flexibly due to limited space and difficult wiring. However, in newly built large-scale modern workshops, due to work efficiency, the work needs to be completed quickly with sufficient power resources through electric turning machines. This results in users needing to prepare multiple turning machines, thereby increasing the cost of turning machines.
[0005] 2. When the manual turning mechanism is not in use, the turning rod on the manual turning mechanism is usually fixed to the turning wheel when using electric drive. As a result, when using electric drive, the turning rod moves with the turning wheel, which leads to an expansion of the turning range. This requires a larger turning space, and the expanded turning range during the turning process makes the turning rod more prone to collision with other objects, which can easily cause damage to the turning rod. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a manual turning mechanism with a limit function, which can effectively solve the problems in the existing technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] This utility model discloses a manual turning mechanism with a limiting function, including a rotating body, a turning body fixedly connected to the top of the rotating body, and a replacement mechanism provided on the outer surface of the turning body.
[0009] The replacement mechanism is used to change the drive mode of the turning gear body and to position it after replacement. The replacement mechanism can also limit the turning gear body during the turning process.
[0010] Furthermore, the replacement mechanism includes a turning rod with a turning hole on its outer surface. The turning rod is positioned above the rotating body, and a turning block is inserted into the top of the turning rod. The bottom end of the turning block is fixedly connected to the top of the turning body.
[0011] Furthermore, a limiting plate is fixedly connected to the outer surface of the turning block, a limiting block is provided at the top of the limiting plate, and an integrated limiting post is fixedly connected to the bottom of the limiting block. The integrated limiting post is threadedly connected to the top of the limiting plate and the top of the turning rod.
[0012] Furthermore, a turning shaft is inserted into the top of the turning block, a pointing plate is fixedly connected to the outer surface of the turning shaft, a pointing seat is fixedly connected to the top of the turning block, and a pointing groove adapted to the pointing plate is opened at the top of the pointing seat.
[0013] Furthermore, a turning plate is fixedly connected to the bottom end of the turning shaft, a positioning rod is slidably connected to the outer surface of the turning block, and a positioning groove adapted to the positioning rod is opened on the outer surface of the turning shaft.
[0014] Furthermore, guide plates are fixedly connected to both sides of the positioning rod, the guide plates are slidably connected to the inside of the turning block, and elastic columns are fixedly connected to the outer surface of the guide plates, the elastic columns are fixedly connected to the inside of the turning block.
[0015] Compared with the known prior art, the technical solution provided by this utility model has the following beneficial effects:
[0016] 1. This utility model fixes or releases the connection between the turning shaft and the turning block by using a positioning rod, thereby freely switching the driving mode of the turning block. This makes the utility model applicable to turning environments of different sizes, which helps users deal with emergencies that may occur during electric turning. This eliminates the need for users to prepare multiple turning mechanisms, which helps reduce turning costs. Furthermore, the cooperation between the pointing plate and the pointing seat can indicate a clear direction when installing the turning shaft, enabling the turning shaft to be installed quickly and thus accelerating the turning efficiency of the turning body.
[0017] 2. This utility model limits the movement of the turning rod and the turning body by a limiting block, thereby allowing the connection relationship between the turning rod and the turning body to be selected independently according to the usage environment of the turning body. In the electric drive state, it can effectively prevent the turning rod from moving with the turning body, thus preventing damage to the turning rod. In the manual turning process, the turning hole can increase the friction between the user and the turning rod, thereby preventing slippage and ensuring that the turning body can turn normally.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] This embodiment provides a manual turning mechanism with a limit function, such as... Figures 1 to 5 As shown, it includes a rotating body 1, with a rotating car body 2 fixedly connected to the top of the rotating body 1, and a replacement mechanism provided on the outer surface of the rotating car body 2.
[0030] The replacement mechanism is used to change the drive mode of the turning gear body 2 and to position it after replacement. The replacement mechanism can also limit the turning gear body 2 during the turning process.
[0031] As a preferred embodiment of this example, Figure 3 , Figure 4 and Figure 5 As shown, the replacement mechanism includes a turning rod 31, with a turning hole 35 on its outer surface. The turning rod 31 is positioned above the rotating body 1. A turning block 32 is inserted into the top of the turning rod 31, and the bottom end of the turning block 32 is fixedly connected to the top of the turning body 2. A limit plate 34 is fixedly connected to the outer surface of the turning block 32. A limit block 33 is provided at the top of the limit plate 34, and an integral limit post is fixedly connected to the bottom end of the limit block 33. The integral limit post is threadedly connected to the top of the limit plate 34 and the top of the turning rod 31. A turning shaft 36 is inserted into the top of the turning block 32, and the outer surface of the turning shaft 36... A guide plate 37 is fixedly connected to the top of the turning block 32, and a guide seat 38 is fixedly connected to the top of the guide seat 38. A guide groove adapted to the guide plate 37 is opened at the top of the guide seat 38. A turning plate 312 is fixedly connected to the bottom of the turning shaft 36. A positioning rod 39 is slidably connected to the outer surface of the turning block 32. A positioning groove adapted to the positioning rod 39 is opened on the outer surface of the turning shaft 36. Guide plates 311 are fixedly connected to both sides of the positioning rod 39. The guide plates 311 are slidably connected to the inside of the turning block 32. An elastic column 310 is fixedly connected to the outer surface of the guide plate 311. The elastic column 310 is fixedly connected to the inside of the turning block 32.
[0032] Working principle:
[0033] Initial limitations:
[0034] The user needs to connect an external micro motor to the turning shaft 36, and connect the output shaft of the micro motor to the top of the turning shaft 36 so that the micro motor can be used as the driving source of the turning shaft 36.
[0035] like Figures 1 to 5As shown, when the user needs to convert the manual turning gear to an electric turning gear, the user only needs to manually rotate the limit block 33 counterclockwise. The limit block 33 drives the integrated limit post at its bottom to rotate counterclockwise. Since the integrated limit post is threadedly connected to the top of the turning gear rod 31 and the top of the limit plate 34, it gradually moves upwards by relying on the thread when the integrated limit post rotates counterclockwise, thereby causing the integrated limit post to gradually detach from the top of the turning gear rod 31 and the top of the limit plate 34. When the integrated limit post is completely detached from the top of the turning gear rod 31 and the top of the limit plate 34, the limit block 33 and the integrated limit post can be removed. At this time, the turning gear... 31 will not move with the movement of the turning block 32, so the connection relationship between the turning rod 31 and the turning body 2 can be selected independently according to the usage environment of the turning body 2. The user can switch the movement state of the turning body 2 to electric by turning on or off the power of the micro motor. In the electric drive state, the turning rod 31 can be effectively prevented from moving with the movement of the turning body 2, thereby preventing damage to the turning rod 31. In addition, the friction between the user and the turning rod 31 can be increased through the turning hole 35 during manual turning, thereby preventing slippage and ensuring that the turning body 2 can turn normally.
[0036] When the user does not need electric turning, the user pulls the positioning rod 39 away from the turning shaft 36, moving the positioning rod 39 away from the turning shaft 36. This moves the end of the positioning rod 39 near the turning block 32 out of the interior of the turning shaft 36, thereby releasing the positioning rod 39 from the turning shaft 36. The turning shaft 36 can then be removed from the turning block 32, and the connection between the turning shaft 36 and the turning block 32 can be released through the positioning rod 39. This allows for a change in the driving method of the turning block 32, making this invention applicable to turning environments of different sizes. It helps users cope with unexpected situations that occur during electric turning, eliminating the need for users to prepare multiple turning mechanisms and reducing turning costs. Furthermore, the cooperation between the pointing plate 37 and the pointing seat 38 provides a clear direction for the installation of the turning shaft 36, enabling quick installation and accelerating the turning efficiency of the turning body 2.
[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
