Description

Technical Field

[0001] The utility model relates to the technical field of pump product production, and specifically, to an adjustable F-type universal barring tool. Background Art

[0002] In recent years, the demand for pump products has been increasing in a stepped manner. The common transmission methods for pump products include direct connection transmission, belt transmission, reducer transmission, etc. Direct connection transmission is a way that the motor and the pump are directly connected without passing through a speed reduction mechanism. During the transmission process, the friction and the resistance of the rotating components are reduced. Therefore, the transmission efficiency is very high.

[0003] In direct connection transmission, the pump and the motor are often connected by an elastic coupling. When mechanical seals are used, to ensure the service life of the mechanical seals to the greatest extent, the installation sequence is to first install the pump coupling, and then assemble components such as the mechanical seal and the rear guard plate. To ensure the normal operation of the pump, after the whole machine is installed, the pump needs to be barred to ensure that all components are correctly installed and the barring is smooth.

[0004] The so-called barring means turning the coupling or the motor shaft of the pump by hand to slowly rotate the rotor of the pump to check the rotational flexibility and component interference. The conventional tool for barring is a crescent wrench, which generally achieves the purpose of barring by cooperating with the keyway of the shaft. However, when the coupling is installed, this wrench cannot be used.

[0005] In view of the above problems, the prior art has not solved them well, which brings trouble to the normal progress of the work in this field. Therefore, there is an urgent need for an adjustable F-type universal barring tool to solve the above problems. Summary of the Utility Model

[0006] The utility model provides an adjustable F-type universal barring tool, which solves the problem that it is not easy to bar the shaft when a coupling is installed on the shaft in the related art.

[0007] The technical solution of the utility model is as follows: an adjustable F-type universal barring tool, including a support rod, a fixed handle, a sliding sleeve and a movable handle. The fixed handle is arranged on the support rod, the sliding sleeve is slidably arranged on the support rod, the movable handle is threadedly connected to the sliding sleeve, and after the movable handle rotates, it is used to abut against or cancel abutting against the support rod. Both the fixed handle and the movable handle are conical.

[0008] Optionally, it further includes a locking ring. The locking ring is arranged on the sliding sleeve, the locking ring is sleeved on the movable handle, and the locking ring is provided with a plurality of locking pieces distributed circumferentially along the locking ring. The plurality of locking pieces are used to jointly clamp the movable handle.

[0009] Optionally, it further includes a locking nut which is threadedly connected to the locking ring. The locking piece has a locking inclined surface. After the locking nut rotates, it abuts or cancels the abutment against the locking inclined surface, so as to enable a plurality of the locking pieces to jointly clamp the movable handle.

[0010] Optionally, the support rod is square.

[0011] Optionally, the sliding sleeve is square-ring-shaped, and the wall thickness of the side where the sliding sleeve is threadedly connected to the movable handle is not less than 10 mm.

[0012] Optionally, it further includes a protective sleeve. The movable handle and the fixed handle are both sleeved with protective sleeves, and the protective sleeves are used to contact the hole wall of the coupling hole.

[0013] Optionally, there are multiple protective sleeves.

[0014] Optionally, it further includes a rubber grip which is sleeved on the end of the support rod.

[0015] Optionally, the rubber grip has anti-slip lines.

[0016] The working principle and beneficial effects of the present utility model are as follows:

[0017] During the production process of pump products, after a coupling is installed on the shaft, the traditional crescent wrench turning tool can no longer cooperate with the keyway on the shaft, resulting in it being unusable. At this time, this adjustable F-type universal turning tool can be used.

[0018] When in use, first, according to the hole pitch on the coupling, slide the sliding sleeve to adjust the position of the movable handle; then rotate the movable handle. By virtue of the threaded connection relationship between the movable handle and the sliding sleeve, make it gradually approach the support rod and finally abut tightly against the support rod, so as to fix the movable handle at the current position; then move the support rod close to the coupling, and insert the fixed handle and the movable handle into two holes on the coupling respectively. In order to ensure uniform force, these two holes are generally the two holes with the farthest distance; finally, the operator swings the support rod to slowly rotate the rotor of the pump to achieve the turning operation. During the turning process, the rotational flexibility of the pump and whether there are problems such as component interference can be checked.

[0019] In the actual production and maintenance of pump products, this adjustable F-type general barring tool has many beneficial effects. First, it solves the problem that traditional barring tools cannot be used after the coupling is installed on the shaft. In the past, when the coupling was installed, a conventional crescent wrench could not be used in conjunction with the keyway of the shaft for barring. Now, with this barring tool, barring operations can be easily performed regardless of whether the coupling is installed or not. Second, the design of the adjustable sliding sleeve enables it to adapt to couplings with different hole distances. By sliding the sliding sleeve and rotating the movable handle, flexible adjustment can be made according to the hole distances of different couplings, greatly improving the versatility of the tool and reducing the trouble of preparing multiple barring tools due to different coupling hole distances. Third, the movable handle and the fixed handle are designed in a conical shape, which can adapt to coupling holes of different sizes. This design ensures a tight fit when the tool faces coupling holes of various sizes, guaranteeing the stability and reliability of barring operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the specific embodiments of the present utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings and other embodiments can be obtained.

[0027] To simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. Additionally, to simplify the drawings for better understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one of them is labeled. In this text, "one" not only means "only this one" but also can mean "more than one", and "several" includes "two" and "more than two".

[0028] In this text, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0029] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] Referring to Figures 1 to 4 , which is the first embodiment of the present utility model, a kind of adjustable F-type universal turning tool is proposed, including a support rod 1, a fixed handle 2, a sliding sleeve 3, and a movable handle 4. The fixed handle 2 is arranged on the support rod 1, the sliding sleeve 3 is slidably arranged on the support rod 1, the movable handle 4 is threadedly connected to the sliding sleeve 3, and after the movable handle 4 rotates, it is used to tighten or cancel tightening the support rod 1. Both the fixed handle 2 and the movable handle 4 are conical.

[0031] In this embodiment, during the production process of pump products, when the coupling is installed on the shaft, the traditional crescent wrench turning tool can no longer cooperate with the keyway on the shaft, resulting in it being unusable. At this time, this adjustable F-type universal turning tool can be used.

[0032] When in use, first, according to the hole pitch on the coupling, slide the sliding sleeve 3 to adjust the position of the movable handle 4; then rotate the movable handle 4, and by virtue of the threaded connection relationship between the movable handle 4 and the sliding sleeve 3, make it gradually approach the support rod 1 and finally tighten the support rod 1, thereby fixing the movable handle 4 at the current position; then bring the support rod 1 close to the coupling, insert the fixed handle 2 and the movable handle 4 into two holes on the coupling respectively. To ensure uniform stress, these two holes are generally the two holes with the farthest distance; finally, the operator swings the support rod 1 to slowly rotate the rotor of the pump to achieve the turning operation. During the turning process, the rotational flexibility of the pump and whether there are component interferences and other problems can be checked.

[0033] In the actual production and maintenance work of pump products, this adjustable F-type general barring tool has many beneficial effects. First, it solves the problem that traditional barring tools cannot be used after the coupling is installed on the shaft. In the past, when the coupling was installed, a conventional crescent wrench could not be used to cooperate with the keyway of the shaft for barring. Now, with this barring tool, barring operations can be easily carried out regardless of whether the coupling is installed or not. Secondly, the adjustable design of the sliding sleeve 3 enables it to adapt to couplings with different hole distances. By sliding the sliding sleeve 3 and rotating the movable handle 4, flexible adjustment can be made according to the hole distances of different couplings, greatly improving the versatility of the tool and reducing the trouble of preparing multiple barring tools due to different coupling hole distances. Moreover, the movable handle 4 and the fixed handle 2 are designed as cones, which can adapt to coupling holes of different sizes. This design ensures a tight fit when the tool faces coupling holes of various sizes, guaranteeing the stability and reliability of barring operations.

[0034] Furthermore, it further includes a locking ring 5. The locking ring 5 is arranged on the sliding sleeve 3. The locking ring 5 is sleeved on the movable handle 4. A plurality of locking pieces 6 are arranged on the locking ring 5 and are distributed circumferentially along the locking ring 5. The plurality of locking pieces 6 are used to jointly clamp the movable handle 4.

[0035] Furthermore, it further includes a locking nut 7. The locking nut 7 is threadedly connected to the locking ring 5. The locking piece 6 has a locking inclined surface 8. After the locking nut 7 rotates, it abuts against or cancels the abutment against the locking inclined surface 8, and is used to make the plurality of locking pieces 6 jointly clamp the movable handle 4.

[0036] In this embodiment, during use, when the movable handle 4 is adjusted to the appropriate position according to the coupling hole distance and rotates to abut against the support rod 1, in order to enhance the stability and durability of the movable handle 4, the locking device is activated. First, rotate the locking nut 7. As the locking nut 7 rotates, it gradually approaches the locking inclined surface 8 on the locking piece 6. When the locking nut 7 contacts the locking inclined surface 8, continue to rotate the locking nut 7. The locking nut 7 generates a squeezing force on the locking inclined surface 8. Under the action of this squeezing force, the plurality of locking pieces 6 start to undergo a slight deformation and gradually approach the movable handle 4. Finally, the plurality of locking pieces 6 jointly clamp the movable handle 4 and share the torque borne by the movable handle 4 during the barring process. In this way, during the barring operation, the movable handle 4 is not only supported by the threaded connection between itself and the sliding sleeve 3, but also jointly bears the pressure by the clamping force of the locking pieces 6.

[0037] This design has significant advantages in practical applications. First of all, it greatly improves the stability of the movable handle 4. During the process of turning the machine by hand, the movable handle 4 needs to bear a certain torque, and relying solely on threaded connection is prone to thread damage. With the addition of the locking ring 5 and the locking piece 6, the force on the movable handle 4 is effectively dispersed, greatly reducing the risk of thread damage and improving the overall stability of the tool. Secondly, it extends the service life of the tool. By sharing the pressure for the movable handle 4, it reduces the situation where the movable handle 4 or the entire tool needs to be frequently replaced due to thread damage caused by long-term stress, saves maintenance costs and time, enhances the reliability of the tool, and reduces production stagnation and safety hazards caused by tool failures.

[0038] Furthermore, the support rod 1 is square.

[0039] In this embodiment, the support rod 1 is designed to be square. During actual operation, when the operator needs to use this tool to turn the machine by hand, hold the square support rod 1. Due to the shape characteristics of the square, it can provide a better grip, so that when the operator swings the support rod 1 forcefully, he can hold the support rod 1 more firmly and is not prone to slipping. During the welding process, the connection between the square support rod 1 and other components is also more stable. For example, when the fixed handle 2 is installed on the support rod 1, the square support rod 1 can provide a larger contact area and a more stable welding angle for welding, making the welding more firm and not prone to loosening or breaking.

[0040] First of all, the square support rod 1 improves the operation safety, and the firm grip can reduce the possibility of accidental accidents caused by hand slipping. Secondly, it enhances the durability of the tool. More firm welding means that the tool can better withstand the action of various forces during long-term use and is not prone to damage to the welding part, extending the service life of the tool. Moreover, the design of the square support rod 1 conforms to the ergonomic principle. The better grip reduces the fatigue of the hand muscles, and the operator can maintain a high work efficiency during long-term work and reduce operation errors caused by fatigue. Finally, from a technological perspective, the square support rod 1 provides convenience for welding, improves production efficiency, and reduces production costs. At the same time, it also makes the overall structure of the tool more stable and reliable.

[0041] Furthermore, the sliding sleeve 3 is square-ring-shaped, and the wall thickness of the side of the sliding sleeve 3 that is threadedly connected to the movable handle 4 is not less than 10 mm.

[0042] In this embodiment, the sliding sleeve 3 is designed to be square-ring-shaped with a non-uniform wall thickness. This shape matches the square support rod 1, enabling the sliding sleeve 3 to slide stably on the support rod 1 without rotation. Meanwhile, the wall thickness of the side of the sliding sleeve 3 that is threadedly connected to the movable handle 4 is set to be not less than 10 mm. Since the sliding sleeve 3 has a sufficient wall thickness, it can ensure the threaded connection length with the movable handle 4. The sliding sleeve 3 can provide stable support for the movable handle 4 through a long threaded connection, ensuring the use strength of the tool.

[0043] Furthermore, it further includes a protective sleeve 9. The protective sleeve 9 is sleeved on both the movable handle 4 and the fixed handle 2, and the protective sleeve 9 is used to contact the hole wall of the coupling hole.

[0044] Furthermore, there are multiple protective sleeves 9.

[0045] In this embodiment, multiple protective sleeves 9 are respectively sleeved on the movable handle 4 and the fixed handle 2, and the protective sleeve 9 is used to contact the hole wall of the coupling hole. During the process of turning the machine by bar, the protective sleeve 9 plays a buffering and protective role, avoiding direct hard friction between the movable handle 4 and the fixed handle 2 and the coupling hole, and reducing the risk of wear and deformation of the coupling hole. If a certain protective sleeve 9 is damaged during long-term use, it can be individually removed and replaced with a new protective sleeve 9 without replacing all the protective sleeves 9 or the movable handle 4 and the fixed handle 2, extending the service life of the tool.

[0046] Furthermore, it further includes a rubber grip 10, and the rubber grip 10 is sleeved on the end of the support rod 1.

[0047] Furthermore, the rubber grip 10 has anti-slip patterns 11.

[0048] In this embodiment, the rubber grip 10 fits closely on the support rod 1 to ensure that it will not easily fall off during use. The rubber grip 10 is designed with anti-slip patterns 11, and these anti-slip patterns 11 can be in different shapes such as raised lines and granular shapes. When it is necessary to perform the operation of turning the machine by bar, the operator holds the rubber grip 10 at the end of the support rod 1. Due to the certain softness and elasticity of the rubber material, it can provide a comfortable holding feeling and relieve hand fatigue. At the same time, the anti-slip patterns 11 increase the friction between the hand and the rubber grip 10, so that when the operator swings the support rod 1 forcefully, the hand will not easily slide, and the tool can be more stably controlled to perform the operation of turning the machine by bar.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
