Abstract

This utility model discloses a quick-connect device for an axial flow pump, belonging to the field of axial flow pump installation technology. It includes a quick-connect frame, with an auxiliary hook fixedly connected to one side and arc-shaped supports fixedly connected to both ends of the other side. The utility model features a clamping assembly. After the pump body reinforcing plate is placed above the two arc-shaped supports, the two L-shaped rods move along the moving groove under the pressure of the side walls of the pump body reinforcing plate. The movement of the L-shaped rods drives the movement of the T-shaped sliding rods, which in turn press against the connecting spring. Then, a rotating screw is rotated, causing it to rotate along the L-shaped rods. When the end of the rotating screw moves to fit against the top wall of the pump body reinforcing plate, the rotation of the rotating screw stops. The rotating screw can clamp and fix the pump body reinforcing plate, ensuring the stability of the pump body reinforcing plate and the two arc-shaped supports, thereby ensuring the stability of the quick-connect installation of the axial flow pump.

Description

Technical Field

[0001] This utility model belongs to the field of axial flow pump installation technology, specifically relating to a quick-connect device for an axial flow pump. Background Technology

[0002] Axial flow pumps are pumps that use the force exerted by the blades of a rotating impeller on the liquid to transport the liquid along the axial direction. They come in several types, including vertical, horizontal, inclined, and through-flow pumps. Axial flow pumps are mainly suitable for low-head, high-flow applications, such as irrigation, drainage, dock drainage, water level regulation in canal locks, or as large circulating water pumps in power plants.

[0003] The existing quick-connect device for axial flow pumps only fixes the inlet pipe of the axial flow pump through the threaded fixing post on the arc bracket, thereby realizing the quick-connect operation of the axial flow pump. This can easily affect the stability of the quick-connect operation. After the staff hangs the items above the auxiliary hook, the items are suspended in the air and are prone to shaking or even falling into the surrounding environment, which can easily damage the items and affect their subsequent use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-connect device for an axial flow pump, comprising a quick-connect frame, an auxiliary hook fixedly connected to one side of the quick-connect frame, and arc-shaped supports fixedly connected to both ends of the other side of the quick-connect frame, a pump body reinforcing plate provided above the two arc-shaped supports, an axial flow pump fixedly connected above the pump body reinforcing plate, a support assembly provided on the side wall of the quick-connect frame and below the auxiliary hook, and a clamping assembly provided between the arc-shaped supports and the pump body reinforcing plate.

[0006] Preferably, the clamping assembly includes an L-shaped rod and a rotating screw. An L-shaped rod is provided on each of the two arc-shaped supports on opposite sides. A rotating screw is threaded onto the L-shaped rod, and a clamping plate is fixedly connected to one end of the rotating screw.

[0007] Preferably, the clamping assembly further includes an arc-shaped plate and a movable component. The arc-shaped plate is fixedly connected to one side of the two arc-shaped supports that are far apart from each other and located on the periphery of the L-shaped rod. A movable component is provided between the arc-shaped plate and the L-shaped rod.

[0008] Preferably, the movable component includes an end plate, a movable groove, a connecting spring, and a T-shaped slide rod. A movable groove is provided on the arc-shaped plate at the position corresponding to the L-shaped rod. End plates are fixedly connected to both ends of the movable groove below the arc-shaped plate. A T-shaped slide rod is fixedly connected to one end of the L-shaped rod. A connecting spring is fixedly connected between the T-shaped slide rod and the end plate.

[0009] Preferably, a guide post is fixedly connected between the two end plates, and a guide hole is provided on the T-shaped slide rod at the position corresponding to the guide post.

[0010] Preferably, a pressure plate is fixedly connected to one end of the rotating screw near the pump body reinforcing plate, and a rubber pad is fixedly connected to the side of the pressure plate near the pump body reinforcing plate.

[0011] Preferably, the support assembly includes a support plate and a vertical frame. The vertical frame is fixedly connected to the side wall of the quick-connect frame and below the auxiliary hook, and a support plate is provided at one end of the vertical frame.

[0014] Preferably, a guide slider is fixedly connected to the side of the threaded sleeve away from the transmission rod, and a guide groove is provided on the inner side wall of the vertical frame at the position corresponding to the guide slider.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model is equipped with a clamping assembly. After the pump body reinforcing plate is placed above the two arc-shaped supports, the two L-shaped rods are squeezed by the side walls of the pump body reinforcing plate and move along the moving groove. The movement of the L-shaped rods drives the movement of the T-shaped slide rods. The movement of the T-shaped slide rods squeezes the connecting springs. Then, the rotating screw is rotated to make it rotate and move along the L-shaped rods. When the end of the rotating screw moves and fits against the top wall of the pump body reinforcing plate, the rotation of the rotating screw is stopped. The rotating screw can be used to clamp and fix the pump body reinforcing plate, ensuring the stability of the pump body reinforcing plate and the two arc-shaped supports, and thus ensuring the stability of the quick-connect installation of the axial flow pump.

[0017] 2. This utility model features a support assembly. When the axial flow pump needs to be quickly connected to mechanical equipment, the worker first hangs their personal belongings on the auxiliary hook, then holds the turntable and applies force to rotate it. The rotation of the turntable drives the threaded rod to rotate, which in turn drives the threaded sleeve to move. The movement of the threaded sleeve drives the transmission rod to move inside the opening, and the movement of the transmission rod drives the support plate to move and fit against the bottom wall of the item. Then, the rotation of the threaded rod is stopped, which facilitates the adjustment of the height of the support plate. In this way, the support plate can be used to support items of different sizes, ensuring the stability of the suspended items. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 The present invention provides the following technical solution: a quick-connect device for an axial flow pump, including a quick-connect frame 7, an auxiliary hook 6 fixedly connected to one side of the quick-connect frame 7, and arc-shaped brackets 2 fixedly connected to both ends of the other side of the quick-connect frame 7. A pump body reinforcing plate 3 is provided above the two arc-shaped brackets 2, and an axial flow pump 1 is fixedly connected above the pump body reinforcing plate 3. A support component 5 is provided on the side wall of the quick-connect frame 7 and below the auxiliary hook 6. A clamping component 4 is provided between the arc-shaped brackets 2 and the pump body reinforcing plate 3.

[0026] Specifically, the clamping assembly 4 includes an L-shaped rod 43 and a rotating screw 44. An L-shaped rod 43 is provided on each of the two arc-shaped supports 2 on opposite sides. A rotating screw 44 is threaded onto the L-shaped rod 43, and a clamping plate 45 is fixedly connected to one end of the rotating screw 44.

[0027] By adopting the above technical solution, after placing the pump body reinforcing plate 3 above the two arc-shaped supports 2, the rotating screw 44 is rotated to move along the L-shaped rod 43. When the end of the rotating screw 44 moves to fit against the top wall of the pump body reinforcing plate 3, the rotation of the rotating screw 44 is stopped. The rotating screw 44 can be used to press and fix the pump body reinforcing plate 3, ensuring the stability of the placement of the pump body reinforcing plate 3 and the two arc-shaped supports 2, thereby ensuring the stability of the axial flow pump 1 installation.

[0028] Specifically, the clamping assembly 4 also includes an arc-shaped plate 41 and a movable component 42. The arc-shaped plate 41 is fixedly connected to the side of the two arc-shaped supports 2 that is far apart from each other and located on the periphery of the L-shaped rod 43. The movable component 42 is provided between the arc-shaped plate 41 and the L-shaped rod 43.

[0029] By adopting the above technical solution, after the pump body reinforcing plate 3 is placed above the two arc-shaped brackets 2, the two L-shaped rods 43 are squeezed by the pump body reinforcing plate 3 and move along the arc-shaped plate 41 under the action of the moving part 42, so as to avoid the L-shaped rods 43 affecting the placement operation of pump body reinforcing plates 3 of different sizes.

[0030] Specifically, the movable component 42 includes an end plate 421, a movable groove 422, a connecting spring 423, and a T-shaped slide rod 424. The movable groove 422 is provided on the arc-shaped plate 41 at the position corresponding to the L-shaped rod 43. The end plate 421 is fixedly connected to both ends of the movable groove 422 below the arc-shaped plate 41. The T-shaped slide rod 424 is fixedly connected to one end of the L-shaped rod 43. A connecting spring 423 is fixedly connected between the T-shaped slide rod 424 and the end plate 421.

[0031] By adopting the above technical solution, after the pump body reinforcing plate 3 is placed above the two arc-shaped brackets 2, the two L-shaped rods 43 are squeezed by the side walls of the pump body reinforcing plate 3 and move along the moving groove 422. The movement of the L-shaped rods 43 drives the T-shaped slide rod 424 to move. The movement of the T-shaped slide rod 424 squeezes the connecting spring 423, which facilitates the adjustment of the distance between the two L-shaped rods 43 and avoids the L-shaped rods 43 from affecting the placement operation of pump body reinforcing plates 3 of different sizes.

[0032] Specifically, guide posts are fixedly connected between the two end plates 421, and guide holes are provided on the T-shaped slide rod 424 at the positions corresponding to the guide posts.

[0033] By adopting the above technical solution, during the movement of the T-shaped slide bar 424 between the two end plates 421, the guide post and guide hole can provide guidance for the movement of the T-shaped slide bar 424, thereby improving the stability of the movement of the T-shaped slide bar 424.

[0034] Specifically, a pressure plate 45 is fixedly connected to one end of the rotating screw 44 near the pump body reinforcing plate 3, and a rubber pad is fixedly connected to the side of the pressure plate 45 near the pump body reinforcing plate 3.

[0035] By adopting the above technical solution, the rotating screw 44 rotates and moves, driving the pressing plate 45 to rotate and move. When the pressing plate 45 moves and fits against the top wall of the pump body reinforcing plate 3, the rotating screw 44 stops rotating. The pressing plate 45 can be used to press the pump body reinforcing plate 3. Under the action of the rubber pad, the friction between the pressing plate 45 and the pump body reinforcing plate 3 can be increased, thereby improving the pressing effect of the pressing plate 45 on the pump body reinforcing plate 3.

[0036] In this embodiment, when it is necessary to quickly connect the axial flow pump 1 to the mechanical equipment, the operator can first use the quick-connect frame 7 to connect with the mechanical arm of the mechanical equipment, then place the axial flow pump 1 on the side wall of the quick-connect frame 7, and place the pump body reinforcing plate 3 on the axial flow pump 1 above the two arc-shaped supports 2. After the pump body reinforcing plate 3 is placed above the two arc-shaped supports 2, the two L-shaped rods 43 are squeezed by the two side walls of the pump body reinforcing plate 3 and move along the moving groove 422. The movement of the L-shaped rods 43 drives the T-shaped slide rod 424 to move. The movement of the T-shaped slide rod 424 squeezes the connecting spring 423. Then, rotate the rotating screw 44 to make it rotate and move along the L-shaped rod 43. When the end of the rotating screw 44 moves and fits against the top wall of the pump body reinforcing plate 3, stop rotating the rotating screw 44. The rotating screw 44 can be used to press and fix the pump body reinforcing plate 3 to ensure the stability of the placement of the pump body reinforcing plate 3 and the two arc-shaped supports 2, thereby ensuring the stability of the quick-connect installation of the axial flow pump 1.

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that the support assembly 5 includes a support plate 51 and a vertical frame 52. The vertical frame 52 is fixedly connected to the side wall of the quick-connect bracket 7 and below the auxiliary hook 6. The support plate 51 is provided at one end of the vertical frame 52.

[0039] Specifically, the support assembly 5 also includes a threaded rod 53, a threaded sleeve 54, a transmission rod 55, and an opening 56. The threaded rod 53 is rotatably connected inside the vertical frame 52. The threaded sleeve 54 is threadedly connected to the outer wall of the threaded rod 53. The transmission rod 55 is fixedly connected to the side wall of the threaded sleeve 54. An opening 56 is provided on the side wall of the vertical frame 52 at the position corresponding to the transmission rod 55.

[0040] By adopting the above technical solution, after the item is suspended above the auxiliary hook 6, force is applied to rotate the threaded rod 53. The rotation of the threaded rod 53 drives the threaded sleeve 54 to move. The movement of the threaded sleeve 54 drives the transmission rod 55 to move inside the opening 56. The movement of the transmission rod 55 drives the support plate 51 to move and fit against the bottom wall of the item. Then, the rotation of the threaded rod 53 is stopped, which makes it easy to adjust the height of the support plate 51. Thus, the support plate 51 can be used to support items of different sizes.

[0041] Specifically, one end of the threaded rod 53 passes through the vertical frame 52 and is fixedly connected to a turntable, and the outer wall of the turntable is provided with anti-slip texture.

[0042] By adopting the above technical solution, when it is necessary to rotate the threaded rod 53, the operator can apply force by holding the turntable to rotate it. The rotation of the turntable drives the threaded rod 53 to rotate, which facilitates the rotation of the threaded rod 53. Moreover, the anti-slip texture can prevent the operator's hand from slipping.

[0043] Specifically, a guide slider is fixedly connected to the side of the threaded sleeve 54 away from the transmission rod 55, and a guide groove is provided on the inner side wall of the vertical frame 52 at the position corresponding to the guide slider.

[0044] By adopting the above technical solution, the threaded sleeve 54 moves and drives the guide slider to move inside the guide groove. With the cooperation of the guide slider and the guide groove, the movement of the threaded sleeve 54 can be guided, and the threaded sleeve 54 can be prevented from rotating with the rotation of the threaded rod 53.

[0045] In this embodiment, when the axial flow pump 1 needs to be quickly connected to the mechanical equipment, the worker first hangs the personal items on the auxiliary hook 6, then holds the turntable and applies force to rotate it. The rotation of the turntable drives the threaded rod 53 to rotate, the rotation of the threaded rod 53 drives the threaded sleeve 54 to move, the movement of the threaded sleeve 54 drives the transmission rod 55 to move inside the opening 56, and the movement of the transmission rod 55 drives the support plate 51 to move and fit against the bottom wall of the item. Then, the rotation of the threaded rod 53 is stopped, which makes it easy to adjust the height of the support plate 51. In this way, the support plate 51 can be used to support items of different sizes and ensure the stability of the suspended items.

[0046] The working principle and usage process of this utility model are as follows: When the axial flow pump 1 needs to be quickly connected to the mechanical equipment, the operator first hangs the personal items on the auxiliary hook 6, then holds the turntable and applies force to rotate it. The rotation of the turntable drives the threaded rod 53 to rotate, which in turn drives the threaded sleeve 54 to move. The movement of the threaded sleeve 54 drives the transmission rod 55 to move inside the opening 56. The movement of the transmission rod 55 drives the support plate 51 to move and fit against the bottom wall of the item. Then, the rotation of the threaded rod 53 is stopped, which facilitates the adjustment of the height of the support plate 51. The support plate 51 can then be used to support items of different sizes, ensuring the stability of the suspended items. The operator then uses the quick-connect frame 7 to connect to the mechanical arm of the mechanical equipment, and then places the axial flow pump 1 on the quick-connect frame. On the side wall of 7, the pump body reinforcing plate 3 of the axial flow pump 1 is placed above the two arc-shaped supports 2. After the pump body reinforcing plate 3 is placed above the two arc-shaped supports 2, the two L-shaped rods 43 are squeezed by the two side walls of the pump body reinforcing plate 3 and move along the moving groove 422. The movement of the L-shaped rods 43 drives the T-shaped slide rods 424 to move. The movement of the T-shaped slide rods 424 squeezes the connecting spring 423. Then, the rotating screw 44 is rotated to make it rotate and move along the L-shaped rods 43. When the end of the rotating screw 44 moves and fits against the top wall of the pump body reinforcing plate 3, the rotation of the rotating screw 44 is stopped. The rotating screw 44 can be used to press and fix the pump body reinforcing plate 3 to ensure the stability of the placement of the pump body reinforcing plate 3 and the two arc-shaped supports 2, thereby ensuring the stability of the quick-connect installation of the axial flow pump 1.

[0047] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
