Description

Technical Field

[0001] The utility model belongs to the technical field of container equipment, and particularly relates to a detachable axial circumferential limiting device. Background Art

[0002] During the design process, if the main shaft inside the container is not completely fixed, the main shaft may move axially or circumferentially during the operation of the equipment, posing a threat to the stable operation of the equipment.

[0003] The problem of unstable spindle fixation: During the operation of the equipment, if the spindle inside the container is not completely fixed, the spindle may move axially or circumferentially. This movement will directly affect the stability and operating efficiency of the equipment.

[0004] The problem of inconvenient spindle disassembly: When the spindle needs to be maintained or replaced, if there is no appropriate disassembly mechanism, the operation may increase complexity and time cost. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide a detachable axial circumferential limiting device to ensure the stability of the main shaft and facilitate the disassembly of the main shaft.

[0006] The technical solution adopted by the utility model is:

[0007] A detachable axial circumferential limit device includes a container shell, a main shaft is arranged in the container shell, two limit plates are rotatably connected to the inner wall of the container shell, a semicircular groove is arranged at the other end of the limit plate, the semicircular grooves of the two limit plates are spliced ​​and clamped to the main shaft, and a locking assembly for locking the two limit plates is connected to the main shaft.

[0008] The utility model combines the limiting plates arranged on the container shell with the locking assembly, and forms a stable triangular structure between the two limiting plates and the container shell to reliably support the main shaft, thereby effectively solving the problem of axial or circumferential movement of the main shaft.

[0009] The utility model provides two split limiting plates, and the main shaft can be conveniently disassembled and assembled by utilizing the opening and closing process of the limiting plates, so that the maintenance and replacement of the main shaft are convenient.

[0010] As a preferred solution of the utility model, two support plate assemblies are fixed on the inner wall of the container shell, and the support plate assemblies are rotatably connected with the limit plate. The support plate assemblies extend out of the inner wall of the container shell, which facilitates the installation of the limit plate.

[0011] As a preferred solution of the utility model, the support plate assembly includes an upper support plate and a lower support plate, both of which are fixed to the inner wall of the container shell, a pin is connected between the upper support plate and the lower support plate, and one end of the limit plate is sleeved on the pin. The limit plate can rotate relative to the pin, which facilitates the splicing or separation of the two limit plates.

[0012] As a preferred solution of the utility model, the limit plate is located between the upper support plate and the lower support plate.

[0013] As a preferred solution of the utility model, the locking assembly includes a stop washer, which is sleeved on the main shaft, and is provided with two outward-extending legs. The limit plate is provided with a stop hole, and the two outward-extending legs are respectively inserted into the stop holes of the two limit plates. The two outward-extending legs on the stop washer are engaged with the stop holes of the limit plates, so that the two limit plates are limited and cannot rotate anymore, ensuring that the two limit plates can clamp the main shaft. When the main shaft needs to be disassembled, the stop washer is removed, and the two limit plates can rotate freely, thereby facilitating the unlocking of the main shaft.

[0014] As a preferred solution of the utility model, the two outwardly extending legs on the stop washer are arranged at 180 degrees on the stop washer.

[0015] As a preferred solution of the utility model, a locking nut for tightening the stop washer is threadedly connected to the main shaft. The locking nut can lock the stop washer to prevent the stop washer from loosening, thereby ensuring that the outward leg on the stop washer is reliably engaged with the stop hole on the limit plate.

[0016] As a preferred solution of the present utility model, the locking nut, the stop washer and the limit plate are arranged in sequence.

[0017] As a preferred solution of the present utility model, the two limiting plates are located on the same horizontal plane.

[0018] As a preferred solution of the present utility model, the diameter of the semicircular groove of the limiting plate is not greater than the diameter of the main shaft.

[0019] The beneficial effects of the utility model are:

[0020] 1. The utility model combines the limit plate and the locking assembly arranged on the container shell, and a stable triangular structure is formed between the two limit plates and the container shell to reliably support the main shaft, effectively solving the problem of axial or circumferential movement of the main shaft.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0031] like Figure 1 to Figure 6 As shown, the detachable axial circumferential limit device of the utility model includes a container shell 1, a main shaft 2 is arranged in the container shell 1, two limit plates 3 are rotatably connected to the inner wall of the container shell 1, and a semicircular groove 31 is arranged at the other end of the limit plate 3. The semicircular grooves 31 of the two limit plates 3 are spliced ​​and clamped with the main shaft 2, and a locking assembly for locking the two limit plates 3 is connected to the main shaft 2.

[0032] The utility model combines the limit plates 3 arranged on the container shell 1 with the locking assembly, and a stable triangular structure is formed between the two limit plates 3 and the container shell 1 to reliably support the main shaft 2, effectively solving the problem of axial or circumferential movement of the main shaft 2.

[0033] The utility model provides two split limiting plates 3 , and utilizes the opening and closing process of the limiting plates 3 to realize convenient disassembly and assembly of the main shaft 2 , thereby facilitating maintenance and replacement of the main shaft 2 .

[0034] Specifically, two support plate assemblies 4 are fixed on the inner wall of the container shell 1, and the support plate assemblies 4 are rotatably connected with the limiting plate 3. The support plate assemblies 4 extend out of the inner wall of the container shell 1, so as to facilitate the installation of the limiting plate 3.

[0035] The support plate assembly 4 includes an upper support plate 41 and a lower support plate 42, both of which are fixed to the inner wall of the container shell 1, and a pin 43 is connected between the upper support plate 41 and the lower support plate 42, and one end of the limit plate 3 is sleeved on the pin 43. The limit plate 3 can rotate relative to the pin 43, so that the two limit plates 3 can be assembled or separated.

[0045] The device has two pairs of four support plates, two upper support plates 41 and two lower support plates 42, which are welded to the inner wall of the container shell 1. The pin holes of the support plates are coaxial, and a pin 43 is inserted in the middle of the pin hole and fixed by welding at both ends. The position of the support plate assembly 4 limits the axial movement distance of the main shaft 2. The limit plate 3 is placed between the upper support plate 41 and the lower support plate 42, and the pin 43 passes through the pin hole of the limit plate 3. The limit plate 3 can rotate around the pin 43. There is a stop hole 32 on the limit plate 3, which cooperates with the outward leg 51 of the stop washer 5 to form a lock. The locking nut 6 is fixedly connected to the main shaft 2 by a thread.

[0046] When using the device, first fix one end of the main shaft 2, rotate the two limit plates 3 to close them to form a limit circle to limit the main shaft 2, the lower end surface of the limit plate 3 presses the upper end surface of the shoulder of the main shaft 2, the stop washer 5 is inserted from the upper end of the main shaft 2, and the outwardly extending legs 51 of the stop washer 5 are embedded in the stop holes 32 of the two limit plates 3 to limit the limit plate 3, and use the locking nut 6 to lock the stop washer 5 to complete the locking of the limit device.
