Description

Technical Field

[0001] This utility model belongs to the technical field of dustproof net self-cleaning system, specifically the braking unit of the dustproof net self-cleaning system. Background Technology

[0002] Dust filter self-cleaning systems are high-efficiency devices for automatically cleaning dust and debris, widely used in industries such as manufacturing, mining, construction, and environmental protection. The core function of this system is to automatically remove accumulated dust from the mesh surface or filter to maintain stable operation and high-efficiency filtration performance. The system typically consists of a cleaning unit, electric drive, braking unit, and transmission device.

[0003] In actual cleaning processes, it is often necessary to stop cleaning the dust screen urgently. Existing technologies directly cut off the power input to interrupt the power of the cleaning device. However, after the power is interrupted, the conventional cleaning plate will continue to run for a distance due to inertia, and cannot maintain its current position when it stops, resulting in poor overall safety and making it impossible to quickly stop and brake the cleaning brush or cleaning plate. Utility Model Content

[0004] The purpose of this invention is to provide a braking unit for a dustproof net self-cleaning system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a braking unit of a dustproof net self-cleaning system, comprising a frame, a braking assembly fixedly installed in the middle of the inner top wall of the frame, a movable plate installed at the bottom end of the braking assembly, a brake pad fixedly installed at the bottom end of the movable plate, a groove formed on the ground of the brake pad, limit guide rails installed at both the left and right ends of the frame, extension ear plates installed at the top of the frame near the left and right sides, linkage components installed on both the left and right sides of the top of the movable plate, one end of the linkage component being movably engaged with the limit guide rail, and a braking assembly installed at the relatively far ends of the two linkage components.

[0006] Before using the device, the extension ear plate must be connected to the external base to ensure that the brake pad is in front of the cleaning plate or cleaning brush. At the same time, adjust the distance between the two locking components so that when the brake pad contacts the cleaning plate or cleaning brush, the two locking components can contact the sides of the cleaning plate or cleaning brush to complete the limiting process. Then connect the brake assembly to the external oil pump to complete the preparation before braking.

[0007] As a further technical solution of this utility model, the braking assembly includes a brake pipe, the top end of which is connected to the inner top wall of the frame, and an oil inlet is fixedly connected to the rear side of the brake pipe near the top end. The oil inlet is connected to an external oil pump, and hydraulic oil is input through the inside of the brake pipe in the external oil pump box.

[0008] As a further technical solution of this utility model, a piston plate is movably sleeved inside the brake pipe, and a piston rod is fixedly installed at the bottom end of the piston plate. The bottom end of the piston rod passes through the bottom end of the brake pipe and is connected to the middle of the top end of the movable plate.

[0009] As a further technical solution of this utility model, a limiting spring is movably sleeved on the outer side of the piston rod, and the upper and lower ends of the limiting spring are respectively connected to the bottom end of the piston plate and the inner bottom wall of the brake pipe.

[0010] By activating the external oil pump, hydraulic oil is introduced into the brake pipe, simultaneously applying force to the piston plate. This causes the piston plate and piston rod to move downwards, compressing the limit spring. The piston rod then pushes the movable plate downwards, increasing the distance between the movable plate and the frame. This, in turn, causes the brake pads at the bottom to move downwards until they are in contact with the cleaning plate and cleaning brush, applying force to them. Through friction, the brakes stop moving, completing a rapid braking process and preventing the cleaning brush or cleaning plate from continuing to move.

[0011] As a further technical solution of this utility model, the linkage component includes a first fixed seat, which is symmetrically installed on one side of the top of the movable plate. The end of the first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0012] As a further technical solution of this utility model, a guide block is installed on the top of each of the second fixed seats. The guide block is movably engaged with the limiting guide rail, and one side of the guide block is connected to the locking component.

[0013] As a further technical solution of this utility model, the locking assembly includes an electric push rod, one end of which is connected to one side of the guide block. An installation plate is fixedly installed at the output end of the electric push rod. A clamping plate is fixedly installed on the bottom end of the installation plate near the movable plate, and a locking rod is fixedly installed on the bottom end of the installation plate away from the movable plate.

[0014] The downward displacement of the movable plate drives the two first fixed seats to move downward. At this time, the two connecting rods move closer to the center and apply tension to the two guide blocks. The two guide blocks then move closer to each other under the guidance of the limit rail, and drive the two locking components to move closer to each other. The two clamping plates then move closer to each other, contacting the sides of the cleaning plate or cleaning brush to complete the side locking. At the same time, the electric push rod can be opened to move the locking rod closer to the dustproof net until the locking rod is inserted into the interior of the dustproof net to complete further locking, maintain the current position of the cleaning plate and cleaning brush, and improve overall safety.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By turning on the external oil pump, the hydraulic oil can be input into the brake pipe and a force is applied to the piston plate. At this time, the piston plate and piston rod move down and compress the limit spring. At this time, the piston rod can push the movable plate to move down. At this time, the distance between the movable plate and the frame increases, and the brake pad at the bottom moves down until it is close to the cleaning plate and cleaning brush, and a force is applied to them. Through the friction force, it is driven to stop running, completing the rapid braking process and preventing the cleaning brush or cleaning plate from continuing to move.

[0017] (2) The present invention drives the two first fixed seats to move downward by the downward displacement of the movable plate. At this time, the two connecting rods move closer to the center and apply a pulling force to the two guide blocks. At this time, the two guide blocks move closer to each other under the guidance of the limiting guide rail and drive the two locking components to move closer to each other. At this time, the two clamping plates move closer to each other and contact the two sides of the cleaning plate or cleaning brush to complete the side locking. At the same time, the electric push rod can be opened to make the locking rod move closer to the dustproof net until the locking rod is inserted into the interior of the dustproof net to complete further locking, maintain the current position of the cleaning plate and cleaning brush, and improve the overall safety.

[0023] 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.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, the braking unit of the dustproof net self-cleaning system includes a frame 1. A braking component 8 is fixedly installed in the middle of the inner top wall of the frame 1. A movable plate 5 is installed at the bottom end of the braking component 8. A brake pad 6 is fixedly installed at the bottom end of the movable plate 5. A groove is opened on the ground of the brake pad 6. Limiting guide rails 2 are installed at both the left and right ends of the frame 1. Extension ear plates 3 are installed at the top of the frame 1 near the left and right sides. Linkage components 7 are installed on both the left and right sides of the top of the movable plate 5. One end of the linkage component 7 is movably engaged with the limiting guide rail 2. The brake component 8 is installed at the ends of the two linkage components 7 that are relatively far apart.

[0025] Before using the device, the extension ear plate 3 needs to be connected to the external base to ensure that the brake pad 6 is in front of the cleaning plate or cleaning brush. At the same time, adjust the distance between the two locking components 4 so that when the brake pad 6 contacts the cleaning plate or cleaning brush, the two locking components 4 can contact the two sides of the cleaning plate or cleaning brush to complete the limiting process. Then connect the brake component 8 to the external oil pump to complete the preparation before braking.

[0026] like Figure 1 and Figure 3 as well as Figure 4As shown, the braking assembly 8 includes a brake pipe 801. The top end of the brake pipe 801 is connected to the inner top wall of the frame 1. An oil inlet 802 is fixedly connected to the rear side of the brake pipe 801 near the top end. The oil inlet 802 is connected to an external oil pump. Hydraulic oil is input into the brake pipe 801 through the external oil pump box. A piston plate 803 is movably sleeved inside the brake pipe 801. A piston rod 804 is fixedly installed at the bottom end of the piston plate 803. The bottom end of the piston rod 804 passes through the bottom end of the brake pipe 801 and is connected to the middle of the top end of the movable plate 5. A limit spring 805 is movably sleeved on the outer side of the piston rod 804. The upper and lower ends of the limit spring 805 are respectively connected to the bottom end of the piston plate 803 and the inner bottom wall of the brake pipe 801.

[0027] By activating the external oil pump, hydraulic oil can be introduced into the brake pipe 801, simultaneously applying force to the piston plate 803. At this time, the piston plate 803 and piston rod 804 move downwards, compressing the limit spring 805. The piston rod 804 then pushes the movable plate 5 downwards, increasing the distance between the movable plate 5 and the frame 1. This, in turn, causes the brake pad 6 at the bottom to move downwards until it presses against the cleaning plate and cleaning brush, applying force to them. Through friction, the brake pads stop moving, completing the rapid braking process and preventing the cleaning brush or cleaning plate from continuing to move.

[0028] like Figure 1 and Figure 3 As shown, the linkage component 7 includes a first fixed seat 701, which is symmetrically installed on one side of the top of the movable plate 5. The end of the first fixed seat 701 away from the movable plate 5 is movably connected to a connecting rod 704 via a pivot. The ends of the connecting rods 704 away from the first fixed seat 701 are movably connected to second fixed seats 702 via pivots. The top of each second fixed seat 702 is equipped with a guide block 703, which is movably engaged with the limit guide rail 2. One side of the guide block 703 is connected to the locking component 4. The locking component 4 includes an electric push rod 401, one end of which is connected to one side of the guide block 703. The output end of the electric push rod 401 is fixedly mounted with a mounting plate 402. The bottom end of the mounting plate 402 near the movable plate 5 is fixedly mounted with a clamping plate 403, and the bottom end of the mounting plate 402 away from the movable plate 5 is fixedly mounted with a locking rod 404.

[0029] The downward displacement of the movable plate 5 drives the two first fixed seats 701 to move downward. At this time, the two connecting rods 704 move closer to the center and apply a pulling force to the two guide blocks 703. The two guide blocks 703 then move closer to each other under the guidance of the limiting guide rail 2, and drive the two locking components 4 to move closer to each other. At this time, the two clamping plates 403 move closer to each other and contact the two sides of the cleaning plate or cleaning brush to complete the side locking. At the same time, the electric push rod 401 can be opened to make the locking rod 404 move closer to the dustproof net until the locking rod 404 is inserted into the interior of the dustproof net to complete further locking, maintain the current position of the cleaning plate and cleaning brush, and improve overall safety.

[0030] Working principle and usage process:

[0031] Before using the device, the extension ear plate 3 needs to be connected to the external base to ensure that the brake pad 6 is in front of the cleaning plate or cleaning brush. At the same time, adjust the distance between the two locking components 4 so that when the brake pad 6 contacts the cleaning plate or cleaning brush, the two locking components 4 can contact the two sides of the cleaning plate or cleaning brush to complete the limiting process. Then connect the brake component 8 to the external oil pump to complete the preparation before braking.

[0032] Turning on the external oil pump allows hydraulic oil to be input into the brake pipe 801, simultaneously applying force to the piston plate 803. At this time, the piston plate 803 and piston rod 804 move downwards, compressing the limit spring 805. The piston rod 804 then pushes the movable plate 5 downwards, increasing the distance between the movable plate 5 and the frame 1. This also causes the brake pad 6 at the bottom to move downwards until it is in close contact with the cleaning plate and cleaning brush, applying force to them and stopping them through friction.

[0033] The downward displacement of the movable plate 5 drives the two first fixed seats 701 to move downward. At this time, the two connecting rods 704 move closer to the center and apply a pulling force to the two guide blocks 703. The two guide blocks 703 move closer to each other under the guidance of the limiting guide rail 2, and drive the two locking components 4 to move closer to each other. At this time, the two clamping plates 403 move closer to each other and contact the two sides of the cleaning plate or cleaning brush to complete the side locking. At the same time, the electric push rod 401 can be opened to make the locking rod 404 move closer to the dustproof net until the locking rod 404 is inserted into the interior of the dustproof net to complete further locking.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
