Description

Technical Field

[0001] This utility model relates to the field of gearbox protection structures, and in particular to a gearbox bracket limiting protection device for a waste pipe processing tearing machine. Background Technology

[0002] The gearbox of the waste pipe shredder is mounted on a gearbox bracket. Some gearbox brackets include a bracket plate and a support base. The gearbox is set on the bracket plate, and two symmetrical clamps are vertically mounted on the support base. The end of the bracket plate is embedded between the two clamps. A shaft passes through both the clamps and the bracket plate, and both ends of the shaft are fixed to connect the bracket plate and the support base. In this type of gearbox bracket, when the motor drives the gearbox, the end of the bracket plate on one side of the gearbox tends to rotate upward. The bearing passing through the clamps and the bracket plate is subjected to a large shear force, which is prone to breakage after long-term use. This causes the bracket plate to collide with the equipment, resulting in low safety. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a gearbox bracket limiting protection device for a waste pipe processing shredder, which limits and protects the position of the bracket plate, making the shaft less prone to breakage and ensuring high safety.

[0004] The technical solution of this utility model is as follows:

[0005] A gearbox bracket limiting protection device for a waste pipe shredding machine includes a column, a mounting shell, a stop block, and a movable pressing component. The mounting shell is located on the top side of the column, and its cross-section is a groove shape with an open bottom. The stop block is slidably disposed within the mounting shell. The top of the mounting shell on the side away from the column has a movable opening communicating with the interior of the mounting shell. Support blocks are symmetrically arranged on both sides of the movable opening on the mounting shell. The movable pressing component includes a pressing plate, a connecting plate, and a pressing block. The pressing plate and the connecting plate are arranged perpendicular to each other, and their cross-sections are right angled. Rotary shafts for rotatably connecting the support blocks are respectively provided on both sides of the connection between the pressing plate and the connecting plate. The pressing plate extends through the movable opening into the mounting shell and abuts against the top of the stop block. The pressing block is located on the side of the connecting plate near the column.

[0006] In a further technical solution, a limiting groove is formed on the inner sidewall of the mounting shell, and a limiting block with a sliding connection limiting groove is provided on the sidewall of the abutment block.

[0007] In a further technical solution, a buffer pad is provided at the bottom of the abutment block.

[0008] In a further technical solution, a stop is provided on the bottom side of the mounting shell away from the connecting plate, and the stop is flush with the inner wall of the corresponding mounting shell.

[0009] In a further technical solution, friction teeth are provided on the side of the pressure block away from the connecting plate.

[0010] In a further technical solution, a support plate is provided at the bottom of the column, and a connecting rib is provided between the support plate and the side wall of the column.

[0011] The beneficial effects of this utility model are:

[0012] 1. This limit protection device is modified based on the existing gearbox bracket. The abutment is placed above the bracket plate. When the bracket plate of the gearbox bracket presses the abutment, the abutment can press the movable pressing part, so that the connecting plate rotates towards the side of the bracket plate. After rotation, the pressure block is pressed against the side wall of the bracket plate, applying friction force and holding the bracket plate tightly. Together with the mounting shell, it provides limit protection for the bracket plate and improves safety.

[0013] 2. The limit block prevents the stop block from easily detaching from the mounting shell;

[0014] 3. The buffer pad prevents the support plate from directly impacting the stop block when it shakes, thus avoiding damage to the limit protection device;

[0015] 4. The stop block and the pressure block can apply a stable clamping force to the support plate, and the stop block abuts against one side of the support plate, making it less likely for the support plate to shift when it is pressed against the pressure block. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example:

[0022] like Figures 1-2As shown, a gearbox bracket limiting protection device for a waste pipe processing shredder includes a column 10, a mounting shell 30, a stop block 40, and a movable pressing component. The mounting shell 30 is located on the top side of the column 10, and its cross-section is a groove shape with an open bottom. The stop block 40 is slidably disposed within the mounting shell 30. A limiting groove 31 is formed on the inner side wall of the mounting shell 30, and a limiting block 41 that slides through the limiting groove 31 is provided on the side wall of the stop block 40, so that the stop block 40 can only move up and down within the mounting shell 30. A stop block 32 is provided on the bottom side of the mounting shell 30 away from the connecting plate 52, and the stop block 32 is flush with the inner wall of the mounting shell 30 on the corresponding side. An movable opening communicating with the inside of the mounting shell 30 is formed on the top side of the mounting shell 30 away from the column 10, and the movable opening is located on both sides of the movable opening. The mounting shell 30 is symmetrically provided with support blocks 33; the movable extrusion component includes an extrusion plate 51, a connecting plate 52 and a pressure block 53. The extrusion plate 51 and the connecting plate 52 are arranged perpendicularly to each other and have a right angle cross section. The two sides of the connection between the extrusion plate 51 and the connecting plate 52 are respectively provided with rotating shafts 54 for rotating the support block 33. The extrusion plate 51 extends through the movable opening into the mounting shell 30 and abuts against the top of the abutment block 40. When the extrusion plate 51 is horizontal, it can be horizontally attached to the inner top wall of the mounting shell 30. The pressure block 53 is located on the side of the connecting plate 52 near the column 10. When the extrusion plate 51 is horizontal and the abutment block 40 is at the lowest point inside the mounting shell 30, only a gap of 1-2 mm is left between the abutment block 40 and the extrusion plate 51 to limit the displacement distance of the support plate 20.

[0023] The working principle of the above technical solution is as follows:

[0024] The limiting protection device is installed on one side of the support plate 20 via the column 10, so that the abutment 40 abuts against the top side of the support plate 20. When the support plate 20 has an upward rotation tendency, the pressing abutment 40 is moved upward, and the abutment 40 presses the pressing plate 51 to rotate until the pressing plate 51 is horizontally attached to the inner top wall of the mounting shell 30. The connecting plate 52, which rotates with the pressing plate 51, drives the pressure block 53 to press tightly against one side of the support plate 20, and the stop block 32 clamps and holds the support plate 20 tightly, thus cooperating with the mounting shell 30 to limit and protect the support plate 20.

[0025] In another embodiment, such as Figure 1 As shown, a buffer pad 42 is provided at the bottom of the abutment block 40. The buffer pad 42 can be made of rubber. The buffer pad 42 prevents the support plate 20 from directly impacting the abutment block 40 when it shakes, thus avoiding damage to the limiting protection device.

[0026] In another embodiment, such as Figure 1 As shown, friction teeth 55 are provided on the side of the pressure block 53 away from the connecting plate 52.

[0027] The friction teeth 55 can further increase the friction between the pressure block 53 and the support plate 20.

[0028] In another embodiment, such as Figure 2 As shown, a support plate 11 is provided at the bottom of the column 10, and a connecting rib 12 is provided between the support plate 11 and the side wall of the column 10.

[0029] The support plate 11 and the connecting rib 12 are conducive to the stable installation of the column 10.

[0030] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
