Technical Field

[0001] The utility model relates to the technical field of drainage pump limiting, and more specifically, to a limiting structure for a drainage pump of an engineering vehicle. Background Art

[0002] Engineering vehicles refer to various specialized motor vehicles used in non-road transport activities such as construction, maintenance, and rescue operations. Drainage engineering vehicles are primarily used to remove urban waterlogging, waterlogged farmland, and low-lying areas. They are typically equipped with drainage pumps and pipes, enabling them to quickly remove large amounts of water, preventing flooding from impacting urban infrastructure, farmland, and residents' lives.

[0003] At present, the drainage pumps on engineering vehicles are generally placed in the rear compartment or truck bed. Some engineering vehicles do not have effective fixed limits on the drainage pumps. During the movement, the drainage pumps may move and collide, which may easily cause damage to the drainage pumps. Although some engineering vehicles have simple limits, they can only limit drainage pumps of a limited size, and they need to be placed in the position of the limit parts. This process is time-consuming and labor-intensive, the operation is cumbersome, and the work efficiency is low.

[0004] Therefore, it is necessary to provide a limiting structure for a drainage pump of an engineering vehicle to solve the above technical problems. Utility Model Content

[0024] 2. In this solution, when the limiting arc plate is used to limit and fix the bottom position of the drainage pump, the baffle can be used to block and limit the upper middle position of the drainage pump, thereby increasing the limiting center of gravity of the drainage pump and further improving the stability of the drainage pump.

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0041] See also Figure 1-8 A limiting structure for a drainage pump of an engineering vehicle is provided on an engineering vehicle body 1 and is used to limit the drainage pump 2. A storage platform 3 is provided on the engineering vehicle body 1, and also includes: a plurality of slot groups, which are opened on the storage platform 3, and each slot group includes a plurality of shift slots 4 distributed in a ring array, and a connecting column 5 is slidingly provided on the inner wall of the shift slot 4; a limiting arc plate 6 is connected to the top of the connecting column 5, and a baffle 7 is provided on the limiting arc plate 6; a transmission mechanism 8 is provided in the storage platform 3, and is used to drive the plurality of limiting arc plates 6 in each slot group to move synchronously.

[0042] When the drain pump 2 is to be placed on the storage platform 3 of the engineering vehicle body 1 after use, the transmission mechanism 8 first drives the multiple limiting arc plates 6 in each slot group to move synchronously. At this time, the limiting arc plates 6 are moved away from each other, that is, the limiting arc plates 6 spread outward. The limiting arc plates 6 are moved along the displacement slots 4 through the connecting column 5, and the area between the limiting arc plates 6 is increased. Then, the drain pump 2 is placed on the storage platform 3 and located between the limiting arc plates 6. A drain pump 2 is placed in each slot group. Then, the transmission mechanism 8 drives the multiple limiting arc plates 6 in each slot group to move synchronously toward each other, that is, the limiting arc plates 6 are moved toward the center. Finally, the drain pump 2 is fixed by the limiting arc plates 6, thereby ensuring the stability of the drain pump 2, greatly preventing the drain pump 2 from moving and colliding during movement, improving the protection effect and service life of the drain pump 2, and having strong practicality. Furthermore, the transmission mechanism 8 enables the limiting arc plate 6 to move different distances, thereby being able to limit and fix drainage pumps 2 of different sizes. The invention has a wide range of applications, can meet the use requirements in different situations, has high flexibility, and can be widely promoted and used.

[0043] At the same time, the limiting arc plate 6 will drive the baffle 7 to move together when it moves. When the limiting arc plate 6 is limiting and fixing the bottom position of the drainage pump 2, the baffle 7 can block and limit the upper middle position of the drainage pump 2, thereby improving the limiting center of gravity of the drainage pump 2, further improving the stability of the drainage pump 2, and having strong practicality.

[0044] Before the drainage pump 2 is placed on the storage table 3, after the transmission mechanism 8 drives multiple limit arc plates 6 to spread outward, the drainage pump 2 can be placed more conveniently between the various limit arc plates 6. There is no need for manual repeated alignment of the positions, which can save a lot of manpower and time. The operation is simple and convenient, which greatly improves the work efficiency and has a good use effect.

[0045] In this embodiment, preferably, please refer to Figure 2-6 The storage platform 3 has a cavity formed inside. The transmission mechanism 8 includes a transmission disk 81 that is rotatably disposed in the cavity. The transmission disk 81 has a plurality of arc grooves 82 formed evenly thereon. Slide posts 83 are slidably disposed in the arc grooves 82. A slide rail 84 is provided on the inner wall of the cavity. A slide rod 85 is slidably disposed on the slide rail 84. The bottom of the connecting column 5 is connected to the slide rod 85. A driving component 86 is provided in the cavity to drive the transmission disk 81 to rotate. The driving component 86 drives the transmission disk 81 to rotate. The rotation of the transmission disk 81 drives the slide posts 83 to move through the arc grooves 82, causing the slide posts 83 to move along the arc grooves 82. The slide posts 83 drive the slide posts 85 to slide along the slide rails 84. The movement of the slide posts 85 simultaneously drives the connecting column 5 to move, which in turn drives the limiting arc plate 6 to move.

[0046] In this embodiment, preferably, please refer to Figure 2-6 The driving component 86 includes a rotating shaft 861 and a driving rod 863, both of which are rotatably disposed within the cavity. The transmission plate 81 is connected to the rotating shaft 861, and a worm gear 862 is also disposed on the rotating shaft 861. One side of the driving rod 863 is provided with a worm 864 that meshes with the worm gear 862, and the other side extends outside the storage platform 3. Rotation of the driving rod 863 drives the worm 864, which in turn drives the worm gear 862 and the rotating shaft 861, which in turn drives the transmission plate 81. Due to the self-locking nature of the worm gear 862 and worm 864, the rotating shaft 861 and the transmission plate 81 can only be driven by the rotation of the driving rod 863, and not vice versa. This improves the stability of the subsequent limiting arc plate 6 in limiting the position of the drainage pump 2.

[0047] One end of the driving rod 863 extending outside the storage platform 3 is provided with a rotating wheel 18. The driving rod 863 is driven to rotate by rotating the rotating wheel 18, thereby making the operation of the staff more convenient.

[0048] In this embodiment, preferably, please refer to Figure 2-4 An adjustment plate 9 is movably inserted into the interior of the baffle 7. The adjustment plate 9 is arranged on the limiting arc plate 6. A plurality of fixing holes 10 are evenly opened on the adjustment plate 9. A first bolt 11 that matches the fixing hole 10 is threadedly connected to the baffle 7. After the first bolt 11 is screwed out of the fixing hole 10, the baffle 7 can be slid up and down along the adjustment plate 9, thereby adjusting the height of the baffle 7. The height limit of the baffle 7 on the drainage pump 2 can be adjusted according to the different specifications of the drainage pump 2 or the specific situation. The baffle 7 has strong applicability and meets the needs of various situations. The baffle 7 can also be moved along the adjustment plate 9 so that the baffle 7 is sleeved outside most of the adjustment plate 9, thereby reducing the length of the baffle 7 and the adjustment plate 9, facilitating transportation and saving space, etc., and having strong practicality. After the adjustment is completed, the baffle 7 can be fixed by screwing the first bolt 11 into the fixing hole 10.

[0049] In this embodiment, preferably, please refer to Figure 2-4 and Figure 7-8An adapter plate 12 is rotatably mounted on the limiting arc plate 6. The adapter plate 12 is connected to the adjustment plate 9. A screw hole 13 is formed on the adapter plate 12, and a second bolt 14 is threadedly connected to the screw hole 13. The limiting arc plate 6 is also provided with a limiting hole 15 that is compatible with the second bolt 14. By rotating the adjustment plate 9 and the adapter plate 12, the baffle 7 and the adjustment plate 9 are transformed from a vertical position to a horizontal position. The drain pump 2 is then placed between the limiting arc plates 6 on the storage platform 3. This reduces the interference of the baffle 7 on the drain pump 2 and eliminates the need to lift the drain pump 2 up and then lower it, making operation more convenient and effective. Furthermore, the horizontal baffle 7 and adjustment plate 9 are more convenient to transport and save space. After the drain pump 2 is positioned, the baffle 7 and adjustment plate 9 are rotated to a vertical position. The second bolt 14 is then screwed into the screw hole 13 and the limiting hole 15 to secure the adapter plate 12, baffle 7, and adjustment plate 9.

[0050] In this embodiment, preferably, please refer to Figure 2 、 Figure 4 and Figure 7 The drainage pump 2 is provided with a hanging piece 16, and the baffle 7 is provided with a binding ring 17. After the limiting arc plate 6 and the baffle 7 have limited the drainage pump 2, the binding belt can be passed through the hanging piece 16 and the binding ring 17 respectively, so as to further limit the drainage pump 2 and make it more stable.
