Description

Technical Field

[0001] The utility model relates to the technical field of sand cleaning devices, in particular to a sand cleaning device for the surface of a fixed-disk trolley. Background Technique

[0002] At present, in the automatic production line of the casting process, a fixed-disk trolley is used to support the sand box. A plurality of grooves which are parallel to each other at intervals and extend along the length direction are formed on the surface of the fixed-disk trolley for supporting the sand box. There may be residual adhering sand in the grooves on the surface of the fixed-disk trolley. A large amount of water vapor is formed on the panel of the fixed-disk trolley due to the heat dissipation of the sand box. After cooling, the sand is bonded to the panel of the fixed-disk trolley and the thickness reaches more than 20 mm, which is difficult to clean. During the production of castings, when producing products with a small sand intake in the lower mold and a deep cavity, and the surface of the fixed-disk trolley is not cleaned in time, the sand mold is prone to cracking, causing the castings to deform and be scrapped, with low safety and easy to have safety problems.

[0003] In order to solve the above problems, at present, most of them choose to install a plurality of rubber scraping heads corresponding to the lower grooves respectively on the moving scraping frame above the fixed-disk trolley, and drive the scraping heads to move in the grooves to clean the accumulated sand by moving the moving scraping frame. On the one hand, the rubber scraping heads not only have a high cost, but are also easy to be damaged and need to be replaced frequently, wasting a lot of labor costs. Content of the Utility Model

[0004] In order to solve the technical problems in the background technique, the utility model proposes a sand cleaning device for the surface of a fixed-disk trolley.

[0005] A sand cleaning device for the surface of a fixed-disk trolley proposed by the utility model includes a moving scraping frame. The lower end of the moving scraping frame is installed with a scraping plate for cleaning the accumulated sand through a plurality of connecting plates. The scraping plate extends along the width direction of the surface of the fixed-disk trolley. The scraping plate is made of metal material, and a plurality of convex plates corresponding to a plurality of grooves on the surface of the lower fixed-disk trolley respectively are arranged at the lower end of the scraping plate.

[0006] Preferably, a plurality of mounting plates are fixedly arranged at intervals along the length direction of the upper part of the scraping plate. A first cross bar and a second cross bar are arranged between adjacent connecting plates. The first cross bar is arranged above the second cross bar and is parallel to each other. The upper part of the mounting plate is rotatably sleeved on the second cross bar, and a plurality of elastic members are sleeved on the second cross bar. The rear end of the elastic member is supported on the first cross bar, and the front end is supported on the scraping plate. When the moving scraping frame drives the scraping plate to move and encounters an obstacle, the scraping plate rotates backward and lifts up due to the elastic action of the elastic member.

[0007] Preferably, the elastic member is a cylindrical torsion spring with an angle of 180°.

[0008] Preferably, the scraping plate is made of manganese steel.

[0009] In summary, the utility model has the following beneficial effects: By installing a scraper at the lower end of the movable scraping frame, the scraper extends along the width direction of the surface of the fixed-disk trolley. Multiple convex plates corresponding to the grooves one by one are provided at the lower end of the scraper. There is no need to set a scraping head at each groove, which reduces the cost. Moreover, the scraper is made of metal, with high wear resistance, not easy to be damaged, long service life, and no need to be replaced frequently, and the cleaning effect is better.

[0010] Additional aspects and advantages of the utility model will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the utility model. Brief Description of the Drawings

[0015] The embodiments of the utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model and should not be construed as a limitation of the utility model.

[0016] As Figure 1-2 shown, a sand cleaning device for the surface of a fixed-disk trolley proposed in this embodiment includes a movable scraping frame 1. A scraper 2 for cleaning accumulated sand is installed at the lower end of the movable scraping frame 1 through a plurality of connecting plates 4. The scraper 2 extends along the width direction of the surface of the fixed-disk trolley. The scraper 2 is made of metal, and a plurality of convex plates 3 corresponding to a plurality of grooves on the surface of the lower fixed-disk trolley one by one are provided at the lower end of the scraper 2. Specifically, the scraper 2 is made of manganese steel. Manganese steel, also known as manganese alloy steel, is a high-strength steel mainly used in harsh working conditions such as those that need to withstand impact, extrusion, and material wear. The most important feature of high manganese steel is that under strong impact and extrusion conditions, the surface layer rapidly undergoes work hardening, so that while maintaining good toughness and plasticity of austenite in the core, the hardened layer has good wear resistance.

[0017] Thus, by installing the scraper 2 at the lower end of the moving scraper frame 1, the scraper 2 extends along the width direction of the surface of the fixed-disk trolley. A plurality of convex plates 3 corresponding to the grooves one by one are provided at the lower end of the scraper 2. The plurality of convex plates 3 are used to clean the accumulated sand in the corresponding grooves. There is no need to set a scraping head at each groove, which reduces the cost and is convenient to control. Moreover, the scraper 2 is made of metal, with high wear resistance, not easily damaged, and a long service life. There is no need to replace it frequently, and the cleaning effect is better and the cost is lower.

[0018] Furthermore, as Figure 1 shown, a plurality of mounting plates 7 are fixedly arranged at intervals along the length direction of the upper part of the scraper 2. A first cross bar 5 and a second cross bar 6 are arranged between adjacent connecting plates 4. The first cross bar 5 is arranged above the second cross bar 6 and is parallel to each other. The upper part of the mounting plate 7 is rotatably sleeved on the second cross bar 6, and a plurality of elastic members are sleeved on the second cross bar 6. The rear end of the elastic member is supported on the first cross bar 5, and the front end is supported on the scraper 2. When the moving scraper frame 1 drives the scraper 2 to move and encounters an obstacle, the scraper 2 rotates backward and lifts due to the elastic action of the elastic member. Specifically, the elastic member is set as a cylindrical torsion spring 8 with an angle of 180°. Thus, when there is a hard obstacle on the surface of the fixed-disk trolley, due to the resistance of the obstacle, the scraper 2 is pushed to rotate backward. At this time, the cylindrical torsion spring 8 is deformed by force. After passing the obstacle, the cylindrical torsion spring 8 restores its deformation and drives the scraper 2 to return to its original position to continue cleaning the accumulated sand, avoiding the scraper 2 being damaged by the hard obstacle, protecting the scraper 2, and extending the service life of the scraper 2.

[0019] Even further, there are three connecting plates 4, which are respectively located at both ends and the middle of the lower end of the moving scraper frame 1. Four groups of mounting plate assemblies are fixed to the upper part of the scraper 2 by screws. Two groups of mounting plate assemblies are respectively installed on both sides of the middle connecting plate. Each group of mounting plate assemblies includes two mounting plates 7. Two cylindrical torsion springs 8 are sleeved on the second cross bar 6 between the two mounting plates 7, and the cylindrical torsion springs 8 installed on each side of the middle connecting plate are opposite in rotation direction.
