Description

TECHNICAL FIELD

[0001] The utility model relates to a belt conveyor alloy mud scraping plate. BACKGROUND

[0002] In the construction of subway tunnels, especially in long-distance full-face slightly weathered granite strata, when EPB / TBM dual-mode shield construction is adopted, the main machine belt conveyor slag discharge system under TBM mode is a key component. However, sometimes part of the residue cannot be completely unloaded by free falling, causing the residue to adhere to the belt and re-enter the shield machine, affecting the normal operation of the belt conveying system. To solve this problem, a mud scraping plate is usually configured at the bottom of the belt conveyor to scrape off the residue adhering to the belt.

[0003] Traditional polyurethane mud scraping plates are widely used due to their good elasticity and less damage to the belt surface. However, in actual application, polyurethane mud scraping plates have the following disadvantages:

[0004] High temperature softening: In high temperature environments, polyurethane materials are prone to softening, causing changes in their shape and size, thereby reducing their effective scraping capacity;

[0005] High-strength hard rock abrasion: In high-strength hard rock strata, hard rock particles generate a large friction force on the polyurethane mud scraping plate, accelerating its wear, and the entire scraper is a hard structure, which may be directly broken or the entire scraper structure may be damaged due to the large force after the scraper is subjected to resistance;

[0006] High maintenance cost: Polyurethane mud scraping plates need to be replaced more frequently, increasing maintenance costs and affecting construction efficiency.

[0007] To address the above problems, the utility model provides a belt conveyor alloy mud scraping plate, aiming to overcome the disadvantages of polyurethane mud scraping plates, improve the durability and scraping efficiency of the mud scraping plate, reduce maintenance costs, and ensure stable operation of the belt conveying system.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Reference Figures 1-5 As shown, an alloy scraper for a belt conveyor includes...

[0031] A fixed rod 10, a U-shaped tool holder 30 mounted on the fixed rod 10, an alloy tool body 40 mounted on the U-shaped tool holder 30, and an alloy scraper 400 clamped at the front end of the alloy tool body 40.

[0032] Furthermore, the end of the U-shaped blade holder 30 connected to the alloy blade body 40 and the alloy scraper 400 has an inclination angle F, where 15°≤F≤20°. The advantage of this design is that when the scraper is used to clean materials with a certain inclination or uneven surface, the inclination angle F allows the scraper blade to better conform to these surfaces, thereby more effectively scraping off the attached material, improving scraping efficiency and cleanliness. For example, when cleaning inclined conveyor belts or curved equipment surfaces, the inclination scraper can better contact these surfaces, reducing scraping dead angles. Moreover, because the inclination angle F makes the contact between the scraper and the material softer, it reduces severe friction and collision during the scraping process, thereby reducing the noise generated during equipment operation. This is of great significance for improving the working environment and reducing noise pollution, especially in places with high noise requirements, such as factory workshops and mines.

[0033] The alloy scraper 400 has a straight or beveled blade. In one embodiment, since the alloy scraper 400 is used to clean hard rock particles, it is preferably designed with a straight blade to enhance its ability to clean hard mud.

[0034] The connecting cylinder 60 passes through the fixing rod 10 and is fixed to the fixing rod 10 by bolts 70;

[0035] A connecting structure 50 is disposed at both ends of the connecting cylinder 60. The connecting structure 50 includes a mounting frame 500, a first connecting cylinder 502 disposed in the middle of the mounting frame 500, a second track 5022 formed on the outer wall of the first connecting cylinder 502 and connected to the second slider 600 disposed in the connecting cylinder 60, and the second slider 600 being connected to a tension spring 5024 disposed in the second track 5022, thereby allowing the connecting cylinder 60 and the fixing rod 10 to slide on the second track 5022 via the second slider 600, while the tension spring 5024 pulls and dissipates the force; a limiting and pulling structure disposed between the mounting frame 500 and the fixing rod 10; and a second connecting cylinder 504 connected to the first connecting cylinder 502 and the connecting cylinder 60, wherein the first track 5020 is symmetrically formed on the outer wall of the other end of the first connecting cylinder 502.

[0036] Since the connecting cylinder 60 and the scraper structure on the fixed rod 10 are hard connected, when the scraper structure encounters a large resistance, the scraper structure may be pulled by the resistance, causing the scraper to break or the equipment to be damaged. In this case, the two ends of the connecting cylinder 60 are designed to be flexible connection, which can greatly improve the service life of the scraper structure. Therefore, when the scraper structure encounters a large resistance, the resistance may be transmitted to the scraper structure due to the hard connection between the connecting cylinder 60 and the scraper structure on the fixed rod 10, which may cause damage to the scraper structure. In order to avoid this situation, the two ends of the connecting cylinder 60 are designed to be flexible connection. When the scraper structure is stressed, the second sliding block 600 on the connecting cylinder 60 will slide along the second track 5022, and the tension spring 5024 will be deformed and elongated due to stress, thereby absorbing and eliminating the force received by the scraper structure, avoiding damage to it. In addition, one end of the second connecting cylinder 504 is provided with a third sliding block (not shown in the figure), which is in sliding connection with the first track 5020 on the outer wall of the first connecting cylinder 502. The first track 5020 is also provided with a tension spring 5024 (not shown in the figure). When the connecting cylinder 60 rotates, the third sliding block will slide along the first track 5020, and further absorb and eliminate the resistance through the tension spring 5024. Through the synergistic effect of the two groups of tension springs 5024, the connecting structure 50 can effectively eliminate the resistance received by the scraper structure, and significantly improve the practicality and service life of the scraper structure.

[0037] Further, in order to ensure that the tension spring can eliminate the resistance received by the scraper structure, the number and elastic coefficient of the tension spring need to be selected according to actual needs.

[0038] Further, in the first track 5020 and the second track 5022 of the embodiment, four tension springs 5024 are connected in parallel, and the elastic coefficient of the tension spring 5024 in the first track 5020 is smaller than that of the tension spring 5024 in the second track 5022. This design can share the resistance together, and the layered design can more effectively cope with different sizes of resistance.

[0039] Further, rubber pads (not shown in the figure) are also provided in the first track 5020 and the second track 5022, which are used in cooperation with the third sliding block and the second sliding block 600, as auxiliary buffer devices, working with the tension spring 5024 to enhance the overall buffering capacity of the system.

[0040] The limiting and pulling structure includes a first pulling piece 506 and a second pulling piece 508, a steel cable 510 arranged between the first pulling piece 506 and the second pulling piece 508, and a limiting ring 512 arranged at both ends of the steel cable 510. Through the cooperation of the steel cable 510 and the limiting ring 512, the movement range of the connecting structure 50 is limited. When the connecting cylinder 60 and the fixed rod 10 are subjected to external force, the steel cable 510 will limit the excessive movement thereof, prevent the connecting structure 50 from exceeding the designed range, thereby avoiding damage to the equipment due to excessive movement, and at the same time, ensuring that the connecting structure 50 remains stable during movement, avoiding unnecessary shaking or deviation due to external force, thereby improving the reliability and durability of the entire device.

[0041] Although the main function of the limiting and pulling structure is to limit the movement range and maintain stability, the elastic properties of the steel cable 510 can also play a role in auxiliary buffering to a certain extent. When the connecting structure 50 is subjected to impact, the steel cable 510 can absorb part of the impact force through its elastic deformation, further protecting the equipment from damage.

[0042] The tail end of the second connecting cylinder 504 is sequentially stacked with a first grommet 5040, a second grommet 5044, and a third grommet 5046, the bottom of the second grommet 5044 and the third grommet 5046 is provided with a plug-in block 5048, the top surface of the first grommet 5040 and the second grommet 5044 is formed with a plug-in slot 5042 for connecting with the plug-in block 5048; further, the sizes of the first grommet 5040, the second grommet 5044, and the third grommet 5046 are sequentially decreased.

[0043] One end of the second connecting cylinder 504 is provided with a third sliding block (not shown in the figure) for sliding connection with the first track 5020.

[0044] The outer wall of the tail end of the second connecting cylinder 504 is formed with an arc-shaped groove 5050, a third track 5052 is formed in the arc-shaped groove 5050, a first sliding block 5054 is in sliding connection with the third track 5052, and a connecting rod 5056 is arranged on the top of the first sliding block 5054 and connected with the bottom of the first grommet 5040, so that when the first sliding block 5054 slides, the first grommet 5040, the second grommet 5044, and the third grommet 5046 are driven to slide left and right.

[0045] It should be noted that the first connecting cylinder 502, the second connecting cylinder 504 and the connecting cylinder 60 are matched components, so when the size of the connecting cylinder 60 changes, the first connecting cylinder 502 and the second connecting cylinder 504 also change, and due to the possible tolerance of the components, the first grommet 5040, the second grommet 5044 and the third grommet 5046 can be clamped and installed, and at the same time, the first slider 5054 can assist the first grommet 5040, the second grommet 5044 and the third grommet 5046 to drive the connecting cylinder 60 to rotate, and cooperate with the connecting structure 50.

When the scraper structure encounters resistance, the flexible connection design of the connecting cylinder 60 makes the second slider 600 slide along the second rail 5022, the tension spring 5024 is deformed and elongated to absorb the resistance, avoiding damage to the scraper. The tension spring 5024 and the rubber pad in the first rail 5020 further enhance the buffering capacity, the limiting pulling structure limits the movement range of the connecting structure 50 through the steel cable 510 and the limiting ring 512, maintains the stability and assists the buffering, the grommet structure and the slider rail design at the tail end of the second connecting cylinder 504 are used for clamping and installing and driving the connecting cylinder 60 to rotate, and cooperate with the connecting structure 50 to ensure that the entire device can effectively cope with resistance during operation, improve the service life and practicality of the scraper structure, and at the same time maintain the stability and reliability of the equipment operation.
