Description

Technical Field

[0001] This utility model relates to the field of slurry pump technology, specifically to an impeller locking device. Background Technology

[0002] There is a type of slurry pump where the impeller and shaft are connected by a thread. During transportation, the pump's working parts spend a considerable amount of time on the road, and the impeller rotates during repeated transfers. Normally, the impeller rotates counterclockwise, and the shaft rotates clockwise. If either the impeller or the shaft rotates in the opposite direction during transportation, the impeller will loosen from the shaft. In severe cases, the impeller may even move forward off the shaft, causing the pump to become loose and unable to operate normally on-site, or even damaging other components. Therefore, improvements are needed to prevent relative rotation between the impeller and shaft during transportation, which could lead to the impeller and shaft loosening. Utility Model Content

[0003] This utility model proposes an impeller locking device, which solves the problem in related technologies where relative rotation between the impeller and shaft occurs during the transportation of slurry pumps, leading to the loosening of the impeller and shaft.

[0004] The technical solution of this utility model is as follows:

[0005] An impeller locking device for securing a shaft to a wooden bracket includes,

[0006] Connectors are provided on the wooden bracket;

[0007] Fasteners for mounting the shaft on the connector.

[0008] As a further technical solution, the connector is rotatably mounted on the wooden bracket and also includes a self-locking mechanism mounted on the wooden bracket. The self-locking mechanism is located on one side of the connector and is used to lock the connector.

[0009] As a further technical solution, the self-locking mechanism includes,

[0010] The mounting bracket is mounted on the wooden support and located on one side of the connector;

[0011] A rotating blocking member is rotatably mounted on the mounting bracket. The rotating blocking member has a guiding surface and a limiting surface. After the connecting member rotates, it abuts against and pushes the guiding surface away. After the connecting member disengages from the guiding surface, it is located below the limiting surface.

[0012] As a further technical solution, the self-locking mechanism also includes,

[0013] A rotating shaft, through which the rotation blocking member is rotatably mounted on the mounting bracket.

[0014] As a further technical solution, the self-locking mechanism also includes,

[0015] A limiting plate is disposed on the rotating blocking member. After the rotating blocking member rotates, the limiting plate abuts against or is not abutted against the mounting bracket.

[0016] As a further technical solution, the rotating blocking member has a limiting part, and the guiding surface and the limiting surface are located at the top and bottom of the limiting part.

[0017] As a further technical solution, both the guiding surface and the limiting surface are inclined.

[0018] As a further technical solution, two mounting brackets are provided at intervals, and the rotating shaft is rotatably disposed between the two mounting brackets.

[0019] The working principle and beneficial effects of this utility model are as follows:

[0026] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, they can be understood as further technical solutions without creative effort. In some drawings, components with the same structure or function are only schematically illustrated, or only one is marked. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-3 As shown, an impeller locking device is used to fix the shaft 1 to the wooden bracket 2, and its specific structure is as follows:

[0030] Connector 3: A connector 3 is provided on the wooden bracket 2. The connector 3 is designed to be compatible with the shaft 1 so that the shaft 1 can be securely mounted on the connector 3.

[0031] Fastener 4: Fastener 4 is used to reliably fix shaft 1 to connector 3. Fastener 4 can be a bolt, clamp, snap-fit, or other structure. Its function is to apply appropriate force to press shaft 1 tightly onto connector 3, preventing shaft 1 from loosening or falling off during operation.

[0032] Self-locking mechanism 5: A self-locking mechanism 5 is added to the wooden bracket 2. It is located on one side of the connector 3 and is used to lock the connector 3 when it is not in use, limiting its position. It does not affect the stacking and storage of the wooden bracket 2. The self-locking mechanism 5 is easy and quick to unlock and convenient to use.

[0033] Mounting bracket 6: The base of the self-locking mechanism 5 is the mounting bracket 6, which is fixed on the wooden bracket 2 and located on one side of the connector 3, providing support and positioning for other components.

[0034] Rotational blocking element 7: The rotational blocking element 7 is rotatably mounted on the mounting bracket 6 via a rotating shaft 10. It is designed with a guide surface 8 and a limiting surface 9, which are located at the top and bottom of the limiting part 12, respectively. When the connecting member 3 rotates, it first abuts against and pushes the guide surface 8. As the connecting member 3 continues to rotate, it gradually disengages from the guide surface 8 and eventually stops below the limiting surface 9, thereby achieving self-locking.

[0035] Guide surface 8 and limiting surface 9: Both surfaces are inclined to ensure that the connector 3 can smoothly slide from the guide surface 8 to the limiting surface 9 during rotation, achieving a smooth transition. The guide surface 8 serves to guide and buffer, while the limiting surface 9 serves to lock the connector 3 to prevent it from rotating in the opposite direction.

[0036] Limiting plate 11: A limiting plate 11 is also provided on the rotating blocking member 7. When the rotating blocking member 7 rotates to the locked position with the connecting member 3, the limiting plate 11 will abut against the mounting bracket 6, further enhancing the self-locking effect; conversely, when unlocking is required, the abutment state between the limiting plate 11 and the mounting bracket 6 is released, allowing the rotating blocking member 7 and the connecting member 3 to resume free rotation. In addition, the limiting plate 11 can be automatically reset by using a tension spring connected to the mounting bracket 6 and the limiting plate 11, or a magnet can be installed on the limiting plate 11 and a magnetic metal can be installed on the mounting bracket 6 to achieve automatic reset of the limiting plate 11 by using magnetic force.

[0037] Rotating shaft 10 and mounting bracket 6: There are two mounting brackets 6 spaced apart. The rotating blocking component 7 is stably rotated between the two mounting brackets 6 via the rotating shaft 10, ensuring that the rotation process is smooth and the force is even.

[0038] In summary, this embodiment provides an impeller locking device, including a connector 3, a fastener 4, and a self-locking mechanism 5 having a guiding surface 8, a limiting surface 9, a rotating shaft 10, a limiting plate 11, and a mounting bracket 6. This device can effectively fix the shaft 1 to the wooden bracket 2, and the self-locking mechanism 5 reliably locks the connector 3, allowing it to be locked when not in use without affecting the stacking and storage of the wooden bracket 2.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
