Technical Field

[0001] This utility model belongs to the technical field of shot blasting equipment, and in particular relates to a rotary trolley for shot blasting machines, which is suitable for workpiece conveying and shot blasting operations. Background Technology

[0002] Shot blasting machines are casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. They can simultaneously perform sand removal, core removal, and cleaning of castings. In shot blasting operations, the workpiece conveying system is a crucial component, directly impacting the equipment's efficiency and cleaning effect. However, traditional rotary trolleys used in shot blasting workshops have the following problems: the overall height of the rotary trolley is relatively high, limiting its usability and making it difficult to meet the maximum blasting height requirements of the workpiece; steel shot splashes during operation can easily damage equipment components, affecting the equipment's lifespan and operational stability, and increasing maintenance and operating costs; steel shot and debris easily accumulate on the table or tracks, increasing running resistance and leading to higher energy consumption. Therefore, there is an urgent need to provide a rotary trolley for shot blasting machines that is compact, has good protective performance, and reduces costs. Utility Model Content

Figure 1-2 As shown, the rotary trolley for the shot blasting machine includes a car body 100, a rotary table 200 rotatably mounted on the car body 100 via a rotary mechanism, a drive system located inside the car body 100, protective mechanisms mounted on the rotary table 200 and the car body 100, and a wheel mechanism located at the bottom of the car body 100. This rotary trolley for the shot blasting machine reduces the overall height of the equipment, lowers the height restrictions of the operating site, and increases the effective space for shot blasting; it effectively prevents steel shot from splashing into the rotary table 200 and the car body 100 and damaging the equipment's components, reducing maintenance and operating costs, extending the equipment's service life, and improving the stability and reliability of equipment operation; it can also promptly and effectively clean steel shot or other debris from the table or tracks, ensuring smooth operation of the rotary trolley and reducing equipment energy consumption.

[0029] This utility model relates to a rotary trolley rotation mechanism 300 for shot blasting machines, used to rotate and clean the workpiece when the rotary trolley reaches the shot blasting cleaning station. The rotary mechanism 300 includes a fully sealed rotary support 310, one end of which is mounted on the trolley body 100, and the other end is connected to the rotary table 200. To effectively prevent dust, the fully sealed rotary support 310 is a double-sealed rotary support. (See attached diagram.) Figure 3 As shown, the double-sealed slewing bearing includes an inner ring and an outer ring that can rotate relative to each other. The inner ring meshes with the gear of the slewing drive mechanism 420. Both the inner and outer rings are provided with precision raceways for mounting rolling elements, transmitting loads, and realizing relative rotation between the two parts of the equipment. The double-sealed slewing bearing is made of elastic material and can achieve lateral and longitudinal sealing.

[0030] Reference Appendix Figure 4The diagram shows the structure of the rotary table 200. The rotary table 200 of the rotary table car for shot blasting machine of this utility model is used to place the workpiece to be shot blasted. The table surface of the rotary table 200 adopts an inclined plate design with an inclination angle of 15-20°. The inclined plate design facilitates the flow of steel shot and protects the equipment below the rotary table 200. The rotary table 200 includes a central positioning spindle 210, located at the center of the lower side of the rotary table 200 platform, for rotational positioning of the rotary table 200; a rotary mechanism positioning ring 220, located on the lower side of the inclined plate of the rotary table 220, for preventing the rotary table 220 from deviating from the center during rotation; a rotary mechanism fixing plate 230, located on the lower side of the inclined plate of the rotary table 200, for fixing the rotary mechanism 300. Preferably, a hanging rubber plate protective plate is also provided at the rotary mechanism fixing plate 230, located 50mm outside the fully sealed rotary support 310; and a reinforcing rib assembly 240, located between the central positioning spindle 210 and the side protective plate 530, preferably in a 30° angled fan-shaped layout.

[0031] The drive system of the rotary trolley for the shot blasting machine of this utility model includes a traveling drive mechanism 410 for driving the trolley body 100 to move back and forth and a rotary drive mechanism 420 for driving the rotary mechanism 300 to rotate. (See attached diagram.) Figure 5 As shown, the trolley drive mechanism 410 drives the drive wheel assembly to move along the base track via a sprocket, thereby driving the trolley body to move and transport the workpiece; see attached diagram. Figure 6 As shown, the rotary drive mechanism 420 drives the rotary mechanism 300 to rotate via gears, thereby driving the rotary table 200 to rotate in the shot blasting station for workpiece surface treatment. The gears of the rotary drive mechanism 420 mesh with the internal gear ring of the fully sealed rotary support 310.

[0032] The protective mechanism of the rotary trolley for a shot blasting machine of this utility model includes multiple sealing plates 510 arranged continuously along the bottom side of the trolley body 100, multiple table surface protective plates 520 arranged on the table surface of the rotary table 200, multiple side protective plates 530 arranged continuously along the outer side of the rotary table 200, and a sealing protective plate 540 arranged at the connection between the rotary table 200 and the rotary mechanism 300. Adjacent sealing plates 510 are tightly connected in pairs to form a closed annular sealing structure around the bottom of the trolley body 100, which can prevent steel shot from splashing and entering the interior of the trolley body 100; see attached figure. Figure 7As shown, each tabletop protective plate 520 is a fan-shaped structure with conical holes. The tabletop protective plates 520 are arranged circumferentially with the center of the rotary table 200 as the center and their sides abut against each other, forming a ring structure covering the entire tabletop. The tabletop protective plates 520 can effectively protect the rotary tabletop from damage, facilitate the flow of steel shot, and reduce the amount of steel shot on the tabletop. The tabletop protective plates 520 can prevent steel shot from splashing and entering the interior of the rotary table 200. The sealing protective plate 540 is a groove-shaped sealing structure, which is continuously arranged circumferentially along the rotary mechanism 300.

[0033] The wheel mechanism of the rotary trolley for the shot blasting machine of this utility model is placed on a base track, and the wheel mechanism can move back and forth along the base track, facilitating the forward and backward transport of the rotary trolley. (See attached reference.) Figure 8 As shown, the wheel mechanism includes an active wheel assembly 610, located at one end of the bottom of the car body 100; a driven wheel assembly 620, located at the other end of the bottom of the car body 100; and a cleaning component, located at the front end of the car body 100, near the active wheel assembly 610. When the rotary car is running, the cleaning component can clean the steel shot and other debris accumulated on the track, which helps the rotary car reduce resistance, reduce equipment energy consumption, and make the rotary car move freely.

[0034] In use, the rotary trolley travels to the shot blasting station under the drive of the trolley drive mechanism 410, and then the rotary drive mechanism 420 drives the fully sealed rotary support 310 to rotate, thereby driving the rotary table 200 to rotate and perform shot blasting.
