Description

Technical Field

[0001] This utility model belongs to the technical field of belt sweepers, and specifically relates to an adjustable belt sweeper. Background Technology

[0002] Belt cleaners are one of the main components of belt conveyors. If the cleaning effect is not good, a lot of coal sludge will accumulate under the belt, resulting in a harsh working environment and harming the health of on-site personnel. Therefore, it is essential to ensure the timely and effective use of the cleaners.

[0003] In the prior art, belts use, for example Figure 2 The sweeper shown has the following disadvantages: 1. Due to the increase in raw coal production, the sweeper skin faces a severe test, requiring replacement on average every three days. Replacement necessitates disassembling the sweeper and re-drilling holes in the skin, requiring 2-3 person-times of labor and taking approximately 2-2.5 hours per replacement, increasing the workload of workers and delaying equipment start-up. 2. When replacing the sweeper skin, because it needs to be in close contact with the conveyor belt surface, issues arise where the skin is too long and the sweeper cannot be installed. This often requires prying down the skin or re-cutting it for reinstallation. Since the sweeper is not adjustable, the lifespan of the skin is significantly shortened, further increasing labor input. Utility Model Content

[0004] To address the technical problems of frequent belt replacements, non-adjustable belt sweepers leading to installation difficulties, rework, and increased manpower, this utility model provides an adjustable belt sweeper.

[0005] The technical solution adopted by this utility model is an adjustable belt sweeper, including symmetrically arranged vertical slides. The upper end of the vertical slides is provided with a claw for fixing and connecting the belt frame. The inner sides of the two vertical slides are provided with vertical grooves. A mounting frame is provided between the vertical slides. The two ends of the mounting frame are slidably connected to the vertical grooves of the two vertical slides respectively. A sweeper skin for belt cleaning is installed on the mounting frame. A stop is provided at the lower end of the vertical slides. A vertically arranged top rod is rotatably connected in the stop. The top rod is threaded and threadedly connected to a fixing nut fixed to the vertical slide. A crank is provided at the lower end of the top rod, and the upper end of the top rod abuts against the end of the mounting frame.

[0006] Furthermore, a retaining nut is located at the lower end of the stop block.

[0007] Furthermore, the vertical carriage is made of rectangular channel steel.

[0008] Furthermore, the mounting bracket uses two back-to-back back plates, with the cleaner skin clamped between the back plates. The back plates have holes at both ends for fixing with bolts and nuts.

[0009] Furthermore, the chuck jaws are U-shaped.

[0010] The adjustable belt sweeper of this invention allows for timely and effective cleaning even when the sweeper belt is severely worn. A single person can tighten the mounting frame using a crank handle, ensuring the sweeper's effectiveness. This not only reduces the frequency of sweeper belt replacement but also decreases personnel input, effectively reducing the labor intensity of employees. Furthermore, it is convenient and quick to operate, making the sweeper safer and more stable, and effectively guaranteeing the normal operation of the equipment. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an adjustable belt sweeper.

[0015] like Figure 1 As shown, an adjustable belt sweeper includes symmetrically arranged vertical slides 1. The upper end of the vertical slides 1 is provided with a claw 11 for fixing and connecting the belt frame. The inner sides of the two vertical slides 1 are provided with vertical grooves 12. A mounting frame 2 is provided between the vertical slides 1. The two ends of the mounting frame 2 are slidably connected to the vertical grooves 12 of the two vertical slides 1. A sweeper skin 21 for belt sweeping is installed on the mounting frame 2. A stop block 13 is provided at the lower end of the vertical slides 1. A vertically arranged top rod 3 is rotatably connected in the stop block. The top rod 3 is threaded and threadedly connected to a fixing nut 14 fixed to the vertical slides 1. A crank handle is provided at the lower end of the top rod 3. The upper end of the top rod 3 abuts against the end of the mounting frame 2.

[0016] In this embodiment, the vertical slide 1 uses two rectangular channel steels that are 1m long, 20cm wide, and 8cm high. The exterior is closed and the interior is open. It is used to fix the mounting bracket 2. The mounting bracket 2 uses two 5cm thick back plates with holes at both ends to allow Φ12 bolts to pass through. The cleaner skin 21 is fixed between the two back plates and locked with nuts and bolts.

[0017] A U-shaped claw 11 is welded to the top of the rectangular channel steel for fixing it to the belt frame. A stop block 13 is welded to the bottom of the rectangular channel steel, and a fixing nut 14 is welded to the lower end of the stop block 13. The top rod 3 is a Φ16 bolt, threaded to the fixing nut 14. Its front end extends into the interior of the rectangular channel steel and abuts against the end of the mounting frame 2, and its rear end is connected to an L-shaped crank handle 31. When the sweeper skin 21 is severely worn, simply rotate the crank handle 31 to move the sweeper skin 21 on the mounting frame 2 upwards to activate the sweeper.

[0018] In adopting such Figure 2 According to the existing belt operation statistics, the sweeper skin 21 needs to be replaced every three days on average. Each replacement requires 2-3 manpower and takes about 1-2 hours. The sweeper skin 21 is frequently replaced, difficult, time-consuming, and inconvenient to disassemble and install.

[0019] After using the adjustable belt sweeper of this embodiment, the replacement cycle of the sweeper belt 21 is 20-30 days, which effectively improves the service life and reduces the frequency of sweeper belt 21 replacement. When the sweeper belt 21 is severely worn, a single person can tighten the mounting bracket 2 by cranking the handle 31 to ensure the timely and effective operation of the sweeper. There is no need to disassemble the sweeper during operation, which also effectively reduces the labor intensity of the workers.

[0020] The adjustable belt sweeper of this embodiment is easy to install and use, and has a high safety factor. It can not only effectively solve the problem of high personnel input, but also achieve the purpose of multiple uses of the sweeper belt, realize the purpose of energy reduction and consumption reduction, ensure the normal operation of the equipment, provide strong support for the transportation of raw coal, and also ensure the safety of maintenance personnel.

[0021] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
