Description

Technical Field

[0001] This utility model relates to the field of gear pump technology, and more specifically, to a gear pump assembly-type quick disassembly and maintenance structure. Background Technology

[0002] Gear pumps are a common type of positive displacement pump, primarily used for conveying liquids of various viscosities. They are widely used in lubrication systems, hydraulic transmission systems, fuel transportation, and material handling in chemical processes. Their working principle is based on one or more pairs of meshing gears. When the gears rotate, a low-pressure zone is created on the suction side, drawing the liquid into the pump. As the gears continue to rotate, the liquid is trapped between the gear teeth and moves along the pump body wall towards the discharge side, ultimately being squeezed out under high pressure, thus achieving continuous liquid delivery.

[0003] Existing gear pumps typically use bolts to secure the end covers on both sides of the pump body. When internal parts need to be inspected or replaced, multiple bolts must be unscrewed sequentially to open the end covers, which is cumbersome and time-consuming. Furthermore, special tools are often required to tighten the bolts during disassembly, increasing the workload for maintenance personnel, reducing maintenance efficiency, and hindering rapid equipment maintenance and troubleshooting.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a gear pump assembly quick disassembly and maintenance structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A gear pump assembly quick disassembly and maintenance structure includes a pump body, a front cover on one side of the pump body and a rear cover on the other side, positioning pins connected to both sides of the surface of the front cover and the rear cover, positioning grooves opened at both ends of the pump body, the positioning pins cooperating with the positioning grooves, adjustment grooves opened on both sides of the inside of the pump body, loading and unloading plates connected to the surface of the front cover and the rear cover, and a quick loading and unloading mechanism provided between the adjustment grooves and the loading and unloading plates.

[0007] Furthermore, in order to enable the rapid installation of the front and rear covers on both sides of the pump body, the quick loading and unloading mechanism includes a telescopic spring connected to both sides inside the adjustment groove. One end of the telescopic spring is connected to a lifting plate, and both ends of the lifting plate are connected to pressure-bearing inclined blocks. The surface of the loading and unloading plate is provided with a limit groove, and the top of the pressure-bearing inclined block cooperates with the limit groove.

[0008] Furthermore, in order to enable the quick disassembly of the two end covers on the pump body, a telescopic groove is opened on one side of the adjustment groove, and a transmission column is rotatably connected to the surface of the lifting plate, with the transmission column cooperating with the telescopic groove.

[0009] Furthermore, in order to enable the lifting plate to retract via the pressure-bearing inclined block during the installation of the loading and unloading plate, a transmission inclined surface is provided at one end of the loading and unloading plate, which cooperates with the inclined surface on one side of the pressure-bearing inclined block.

[0010] Furthermore, in order to enable the front and rear covers to pop out of the pump body quickly when disassembled, a return spring is connected to one side of the positioning groove.

[0011] Furthermore, to prevent the transmission column from being accidentally pressed, a limit block is connected to one side of the transmission column, and a sliding groove is opened on one side of the telescopic groove, with the limit block cooperating with the sliding groove.

[0012] Furthermore, in order to realize the input and output of liquid in the gear pump, an inlet is provided on one side of the pump body and an outlet is provided on the other side.

[0013] The beneficial effects of this utility model are as follows: Through the quick-release mechanism, when the two end covers need to be disassembled for pump maintenance, pressing the transmission columns on both sides of the pump body causes the transmission columns to push the lifting plate to move within the adjustment groove. This prevents the pressure-bearing inclined blocks on both sides of the lifting plate from limiting the end slots of the two loading / unloading plates. At this time, the return spring in the positioning groove can quickly eject the two end covers from both sides of the pump body through its own elasticity, achieving quick disassembly of the front and rear end covers. When the two end covers need to be installed after maintenance, they are installed in the adjustment groove using the loading / unloading plates on both sides of the end covers. At this time, the ends of the loading / unloading plates can squeeze the pressure-bearing inclined blocks on both sides of the lifting plate, allowing the pressure-bearing inclined blocks to be installed in the limiting groove, providing stable limiting for the installation of the loading / unloading plates and the two end covers, achieving quick installation of the front and rear end covers. This gear pump structure eliminates the tedious steps of loosening and installing bolts one by one, allowing the end covers to be quickly opened and reset. Furthermore, no additional tools are required during loading and unloading, greatly shortening the maintenance time of the gear pump and improving equipment maintenance efficiency.

[0017] 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.

[0018] According to an embodiment of the present invention, a quick-disassembly and maintenance structure for a gear pump is provided.

[0019] Example 1: like Figures 1-5 As shown, a gear pump assembly-type quick disassembly and maintenance structure according to an embodiment of this utility model includes a pump body 1, which is composed of a driving gear, a driven gear, and a metal shell. The pump body 1 can realize the suction and discharge of liquid through the meshing of the two gears. A front cover 2 is provided on one side of the pump body 1, and a rear cover 3 is provided on the other side to close both ends of the pump body 1 and ensure the integrity of the internal structure. A pair of positioning posts 4 are connected to both sides of the surface of the front cover 2 and the rear cover 3. Positioning grooves 5 are opened at both ends of the pump body 1. The positioning posts 4 cooperate with the positioning grooves 5 to stabilize and position the front cover 2 and the rear cover 3 during installation. A pair of adjustment grooves 6 are opened on both sides of the interior of the pump body 1. A pair of loading and unloading plates 7 are connected to the surface of the front cover 2 and the rear cover 3. A quick loading and unloading mechanism 8 is provided between the adjustment grooves 6 and the loading and unloading plates 7 to realize the quick installation and removal of the two end covers on the pump body 1.

[0020] like Figures 1-5 As shown, the quick loading and unloading mechanism 8 includes telescopic springs 801 connected to both sides inside the adjusting groove 6. One end of the telescopic spring 801 is connected to a lifting plate 802, and both ends of the lifting plate 802 are connected to pressure-bearing inclined blocks 803. A limit groove 804 is opened on the surface of the loading and unloading plate 7, and the top of the pressure-bearing inclined block 803 cooperates with the limit groove 804. A telescopic groove 805 is opened on one side of the adjusting groove 6. A transmission column 806 is rotatably connected to the surface of the lifting plate 802, and the transmission column 806 cooperates with the telescopic groove 805. A transmission inclined surface 807 is provided at one end of the loading and unloading plate 7, and the transmission inclined surface 807 and the pressure-bearing inclined block 803 are connected to each other. The inclined surfaces on one side of the two end caps cooperate, and the loading and unloading plate 7 is installed in the adjusting groove 6 during installation. When the transmission inclined surface 807 at the end of the loading and unloading plate 7 enters the adjusting groove 6, it can squeeze the pressure inclined block 803, so that the lifting plate 802 can squeeze the telescopic spring 801 and retract towards one side of the adjusting groove 6. When the limiting groove 804 on the surface of the loading and unloading plate 7 moves to correspond to the pressure inclined block 803, the telescopic spring 801 can push the pressure inclined block 803 on the surface of the lifting plate 802 into the limiting groove 804 through its own elasticity, so that the lifting plate 802 limits the installed loading and unloading plate 7. This allows for the rapid installation of the two end caps. When the two end caps need to be removed, pressing the drive columns 806 on both sides of the pump body 1 causes the drive columns 806 to push the lifting plate 802 in the adjusting groove 6 to move, thereby allowing the pressure-bearing inclined blocks 803 on both sides of the lifting plate 802 to slide out of the limiting groove 804, no longer limiting the loading and unloading plate 7. At this time, the two end caps can be quickly removed from the pump body 1. A return spring 9 is connected to one side of the positioning groove 5. When the two end caps are removed, the return spring 9 can eject the positioning column 4 from the positioning groove 5 through its own elasticity. One side of the drive column 806 is connected to A limiting block 10 is connected to the telescopic groove 805, and a sliding groove 11 is opened on one side. The limiting block 10 cooperates with the sliding groove 11. The limiting block 10 limits the sliding of the transmission column 806 in the telescopic groove 805 to prevent the transmission column 806 from being accidentally pressed after the end cover is installed. When the end cover is removed and the transmission column 806 needs to be pressed, the transmission column 806 is rotated so that the limiting block 10 rotates to correspond with the sliding groove 11, so that the transmission column 806 can be pressed and adjusted. One side of the pump body 1 is provided with an inlet 12 and the other side is provided with an outlet 13 to realize the input and output of the pump body 1.

[0021] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0022] In summary, by means of the above-mentioned technical solution of this utility model, the positioning pins 4 on both sides of the front end cover 2 and the rear end cover 3 cooperate with the positioning grooves 5 on both sides of the pump body 1 to install the two end covers on both sides of the pump body 1. When the two end covers are installed, the loading and unloading plate 7 can be installed in the adjusting groove 6. When the transmission inclined surface 807 at the end of the loading and unloading plate 7 enters the adjusting groove 6, it can squeeze the pressure inclined block 803, so that the lifting plate 802 can squeeze the telescopic spring 801 and retract to one side of the adjusting groove 6. When the limiting groove 804 on the surface of the loading and unloading plate 7 moves to the position corresponding to the pressure inclined block 803, the telescopic spring 801 can retract by itself. The spring force pushes the pressure-bearing inclined block 803 on the surface of the lifting plate 802 into the limiting groove 804, so that the lifting plate 802 limits the installation of the loading and unloading plate 7, thereby realizing the quick installation of the two end covers; when the two end covers need to be removed, by pressing the transmission column 806 on both sides of the pump body 1, the transmission column 806 pushes the lifting plate 802 in the adjusting groove 6 to move, so that the pressure-bearing inclined block 803 on both sides of the lifting plate 802 can slide out from the limiting groove 804 and no longer limit the loading and unloading plate 7. At this time, the return spring 9 can pop the positioning column 4 out of the positioning groove 5 through its own elasticity, so as to realize the quick removal of the two end covers from the pump body 1.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
