Description

Technical Field

[0001] This utility model relates to the field of scraper equipment, specifically a scraper clamp with double airbag baffles. Background Technology

[0002] In many applications, traditional clamps operate with the scraper loaded, and during unloading, the air bladder is in a naturally deflated, pressureless state. At this time, the debris scraped by the scraper falls into the upper cavity where the air bladder is installed. Over time, this upper cavity becomes filled with debris. When the upper air bladder is inflated again, it cannot overcome the interference from the debris filling the upper cavity, affecting the loading stroke and causing the blade to fail to adhere to the roller surface. Furthermore, during scraper operation, a large amount of debris scraped off by the scraper also enters the cavity where the upper air bladder is installed, affecting the clamp's adjustment.

[0003] Therefore, it is necessary to provide a scraper clamp with dual airbag baffles. Summary of the Invention

[0004] This utility model provides a scraper clamp with double airbag baffles, which effectively solves the problem that the upper cavity of the existing scraper clamp is easily filled with garbage.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, the scraper clamp with double airbag baffle provided in the embodiment of this application includes a mounting beam 1, a first airbag 2, a second airbag 3, a front mounting plate 4 disposed on the mounting beam 1, a rotating shaft, and a rear mounting plate 5 hinged to the front mounting plate 4 via the rotating shaft. The front mounting plate 4 and the rear mounting plate 5 form an upper cavity and a lower cavity. The first airbag 2 is disposed in the upper cavity, and the second airbag 3 is disposed in the lower cavity. A scraper groove 501 is provided at the upper end of the rear mounting plate 5. A flexible upper baffle 6 is also disposed between the front mounting plate 4 and the rear mounting plate 5, and the first airbag 2 is located below the flexible upper baffle 6.

[0019] In actual use, the scraper 100 is fixed to the rear mounting plate 5 via the scraper groove 501. Airbag 2 slides into the upper cavity through the side opening, and airbag 3 slides into the lower cavity through the side opening. The rear mounting plate 5 rotates by adjusting the air pressure of airbags 2 and 3, thereby changing the angle of the scraper 100. When the rear mounting plate 5 rotates, the flexible upper baffle 6 extends and retracts accordingly. Debris generated by the scraper 100 scraping the roller surface 200 is blocked outside the upper cavity by the flexible upper baffle 6.

[0020] In the above design, the flexible upper baffle 6 can be used to shield the upper cavity, effectively preventing the garbage scraped out by the scraper 100 from entering the fixture and affecting the normal adjustment of the scraper 100.

[0021] Specifically: such as Figure 1 and Figure 2 As shown, the front mounting plate 4 includes a front vertical plate 41 fixedly connected to the mounting beam 1, a front connecting plate 42 hinged to the rear mounting plate 5 at the rear end of the front vertical plate 41, a support plate 43 located at the lower end of the front vertical plate 41 and extending towards the rear mounting plate 5, an inclined baffle 44 located at the upper end of the front vertical plate 41 and inclined towards the rear mounting plate 5, and an L-shaped plate located on the side of the inclined baffle 44 away from the upper cavity. The L-shaped plate and the inclined baffle 44 form a receiving groove with openings on three sides. The flexible upper baffle 6 includes a plate body 62 and a columnar limiting end 61 located at one end of the plate body 62. The columnar limiting end 61 is installed in the receiving groove. The L-shaped plate includes a first plate 45 connected to the inclined baffle 44 and a second plate 46 connected to the upper end of the first plate 45. The distance between the second plate 46 and the inclined baffle 44 is less than the diameter of the columnar limiting end 61 and greater than the thickness of the plate body 62. The front connecting plate 42 has a first hole and the rear mounting plate 5 has a second hole. The rotating shaft passes through the first hole and the second hole to achieve the hinge connection between the front mounting plate 4 and the rear mounting plate 5.

[0022] In actual use, the front mounting plate 4 remains fixed, while the rear mounting plate 5 is adjusted at an angle according to the working requirements of the scraper 100. During assembly, the flexible upper baffle 6 can slide to a predetermined position within the receiving groove before being fixed. The inclined baffle 44 limits the saturation of the first airbag 2, preventing it from shaking up and down.

[0023] In the above design, the structural design of the front mounting plate 4 facilitates the quick movement of the flexible upper baffle 6 to the corresponding position through the receiving groove when assembling the flexible upper baffle 6.

[0024] Specifically: the other end of the plate body 62 is provided with a mounting hole, the upper end of the rear mounting plate 5 is provided with a screw hole, and the plate body 62 is bolted to the rear mounting plate 5.

[0025] When the flexible upper baffle 6 is actually assembled, the columnar limiting end 61 of the flexible upper baffle 6 slides to the predetermined position in the receiving groove, and then the flexible baffle is fixed to the upper end of the rear mounting plate 5 with bolts.

[0026] In the above design, only one end of the flexible upper baffle 6 needs to be bolted, and the other end of the flexible upper baffle 6 is limited by the slot of the receiving groove, which reduces the assembly difficulty of the flexible upper baffle 6 and improves the adjustment convenience of the flexible upper baffle 6.

[0027] Specifically: such as Figure 1 As shown, a flexible lower baffle 7 is provided between the lower end of the front mounting plate 4 and the lower end of the rear mounting plate 5.

[0028] Before the flexible lower baffle 7 is installed, when the scraper 100 scrapes away debris from the roller surface 200, some of the flying debris will enter the lower cavity from the lower openings of the front mounting plate 4 and the rear mounting plate 5 due to airflow disturbance. At the same time, there will also be situations where the scraper 100 is used with the blade facing downwards. After the flexible lower baffle 7 is installed, the debris that would have entered the lower cavity is blocked by the flexible lower baffle 7 on the outside of the lower cavity.

[0029] In the above design, the flexible lower baffle 7 is set to facilitate the blocking of debris from entering the lower cavity.

[0030] Specifically: such as Figure 2 As shown, the rear mounting plate 5 includes a rear vertical plate 51, a rear connecting plate 52 that is hinged to the front mounting plate 4 on the rear vertical plate 51, and a straight plate 53 that is disposed on the rear side of the rear vertical plate 51. The upper end of the straight plate 53 is higher than the upper end of the rear vertical plate 51. A step is provided on the upper end of the rear vertical plate 51. The step and the straight plate 53 form a scraper 100 groove 501.

[0031] In actual use, when the scraper 100 is in operation, the upper front end of the scraper 100 contacts the roller surface 200, and the front side is also limited by the step, while the rear side is limited by the straight plate 53.

[0032] In the above design, the structural design and specific implementation of the rear mounting plate 5 facilitate the installation of the flexible lower baffle 7.

[0033] Specifically: such as Figure 1 and Figure 2 As shown, the lower end of the rear vertical plate 51 is provided with a lateral groove. The lateral groove includes a top wall, a bottom wall, and a side wall. The bottom wall is spaced from the straight plate 53. The lateral groove and the straight plate 53 form a receiving groove 502. The flexible lower baffle 7 includes a flexible plate 71 and a columnar body 72 provided at one end of the flexible plate 71 that extends into the receiving groove 502. The other end of the flexible plate 71 is bolted to the front mounting plate 4.

[0034] In actual use, when the flexible plate 71 is not fixed, the columnar body 72 can slide within the receiving groove 502 along the extension direction of the receiving groove 502. After the flexible plate 71 is bolted to the front mounting plate 4, the columnar body 72 is fixed within the receiving groove 502.

[0035] In the above design, the structural design of the rear vertical plate 51 and the flexible lower baffle 7 facilitates the installation and adjustment of the flexible lower baffle 7.

[0036] Specifically: such as Figure 1 and Figure 2 As shown, the upper end of the front mounting plate 4 is lower than the upper end of the rear mounting plate 5.

[0037] In actual use, the upper airbag is held in place by the front mounting plate 4 and the rear mounting plate 5 on both sides, and the flexible upper baffle 6 is positioned at the upper ends of the front mounting plate 4 and the rear mounting plate 5, respectively, thus the flexible upper baffle 6 has a certain tilt angle. The upper end of the front mounting plate 4 is lower than the upper end of the rear mounting plate 5, allowing the debris scraped off by the scraper 100 to slide down the flexible upper baffle 6 into the clamp.

[0038] In the above design, the front mounting plate 4 and the rear mounting plate 5 are designed to facilitate the sliding off of debris from the flexible upper baffle 6.

[0039] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
