Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a grab-type sewage remover anti-tilting device. Background Art

[0002] Grab-type screen cleaners are commonly used in municipal wastewater treatment facilities, river courses, pumping stations, and other locations. They are designed with either inclined or vertical coarse screens. When cleaning with inclined screens, the curved gripper can cause the center of gravity to shift forward, posing a risk of tipping. This could damage the equipment and have serious consequences for project operations.

[0003] Therefore, in order to ensure that the grab bucket type dirt remover can run safely and stably on the inclined grille, it is particularly important to set an anti-rollover structure in the vertical direction of the claw. Utility Model Content

[0004] The purpose of this solution is to adjust the center of gravity of the gripper when it is running on an inclined grille by adding an adjustable counterweight roller in the vertical direction of the gripper, so as to avoid the gripper tipping due to the forward shift of the center of gravity, and to improve the safety and stability of the gripper.

[0005] A grab-type dirt remover anti-tilting device, comprising:

[0006] A roller is mounted on the back of the gripper, i.e., the vertical portion of the gripper, and the roller serves as a counterweight for adjusting the center of gravity of the gripper when it operates on an inclined grille;

[0007] The connecting plate is installed on the central column of the gripper body and is used to connect the roller to the gripper body. A long hole is opened on the connecting plate along the length direction, and an adjusting bolt is installed in the long hole. The adjusting bolt passes through the long hole and is fixedly connected to the central column. The adjusting bolt and the long hole are used to adjust the installation position of the roller, thereby adjusting the center of gravity of the gripper.

[0008] As a preferred solution of the present invention, a central bearing is provided in the drum, and the drum achieves rolling through the central bearing.

[0009] As a preferred solution of the present invention, two adjusting bolts are provided to improve the fixing strength.

[0010] As a preferred solution of the present invention, the connection plates are installed in a direction perpendicular to the central column, and are provided in two pieces and connected to both ends of the drum.

[0011] As a preferred solution of the present invention, the roller is made of stainless steel 304 or stainless steel 316.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] The utility model can effectively adjust the center of gravity of the claw when running on the inclined grille by adjusting the position of the roller. This design avoids the risk of the claw tipping over due to the forward shift of the center of gravity during the cleaning process, thereby protecting the equipment from damage and ensuring the continuous and stable operation of the project; the long holes and adjustment bolts provided on the connecting plate allow the user to adjust the installation position of the roller according to actual needs, and then fine-tune the center of gravity of the claw. This design enables the device to adapt to grilles with different inclination angles, thereby improving the versatility and flexibility of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1

[0019] like Figure 1 、 Figure 2 As shown, a specific embodiment of the grab anti-tilt device of a grab bucket type sewage remover described in the utility model includes:

[0020] The roller 3 is installed on the back of the gripper, i.e., the vertical part of the gripper. The roller 3 acts as a counterweight to adjust the center of gravity of the gripper when it runs on the inclined grille. A central bearing is provided inside the roller 3, and the roller rolls on the central bearing.

[0021] The connecting plate 1 is mounted on the central column 2 of the gripper body and is used to connect the roller 3 to the gripper body. The connecting plate 1 is installed perpendicular to the central column 2 and is provided in two pieces and connected to both ends of the roller 3. A long hole is opened on the connecting plate 1 along the length direction, and an adjusting bolt 4 is installed in the long hole. The adjusting bolt 4 passes through the long hole and is fixedly connected to the central column 2. The adjusting bolt 4 and the long hole are used to adjust the installation position of the roller 3, thereby adjusting the center of gravity of the gripper;

[0022] Two adjusting bolts 4 are provided to improve the fixing strength.

[0023] In this embodiment, the roller 3 is made of stainless steel 304.

[0024] In other embodiments, stainless steel 316 or other materials that can meet the quality and strength requirements of the counterweight may also be used.

[0025] The working principle of the present invention is as follows: when the grab-type dirt remover runs on an inclined grille, the claw will move with the inclination angle of the grille. Since the curved part of the claw will cause the center of gravity to move forward during the cleaning process, the device installs a roller 3 as a counterweight on the vertical part of the claw. The installation position of the roller 3 can be changed by loosening the adjusting bolt 4 and moving the connecting plate 1 according to factors such as the inclination angle of the grille and the weight and shape of the dirt, thereby adjusting the center of gravity of the claw. At the same time, the central bearing inside the roller 3 realizes rolling, which reduces friction and wear between the roller 3 and the grille and improves the operating efficiency and stability of the equipment.

[0026] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0027] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention. Modifications or deformations that do not involve creative work are still within the scope of protection of the present invention.
