Description

Technical Field

[0001] The utility model relates to the technical field of wet spraying manipulator structures, in particular to a first-level horizontal rotation mechanism of a wet spraying manipulator with simple structure, high connection strength, good protection effect, stable output and high structural stability. Background Art

[0002] As we all know, concrete spraying robots are widely used in construction. They use compressed air or other power sources to transport a precisely proportioned mixture through a pipe and spray it at high speed onto the surface where it solidifies, forming a concrete support layer. Shotcrete technology is simple, cost-effective, and widely applicable, making it a vital tool in various construction applications.

[0003] At present, the mechanism for controlling the rotation of the spray head provided in the existing concrete spraying robot is a rotating and swinging mechanism, which includes a first-level horizontal rotating mechanism and a second-level vertical rotating mechanism. The first-level horizontal rotating mechanism is horizontally connected to the output part of the robot, and the second-level vertical rotating mechanism is perpendicular to the horizontal rotating mechanism and vertically connected to the output end of the first-level horizontal rotating mechanism. Since the output end of the first-level horizontal rotating mechanism is directly connected to the second-level vertical rotating mechanism, the output end of the first-level horizontal rotating mechanism is exposed. Since the concrete wet spraying robot is in a dusty environment for a long time, the exposed part of the output end of the first-level horizontal rotating mechanism at the connection between the first-level horizontal rotating mechanism and the second-level vertical rotating mechanism is easily contaminated by dust, resulting in the output end of the first-level horizontal rotating mechanism being stuck and the output effect being poor, affecting the service life of the first-level horizontal rotating mechanism. At the same time, since the first-level horizontal rotating mechanism is connected to the second-level horizontal rotating mechanism solely by the shaft of the output end, the shaft of the output end of the first-level horizontal rotating mechanism is subjected to increased gravity, and then problems such as poor structural stability occur. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and to provide a one-stage horizontal rotation mechanism for a wet spraying manipulator with a simple structure, high connection strength, good protection effect, stable output and high structural stability.

[0006] A first-level horizontal rotation mechanism of a wet spraying manipulator is provided with a first-level output oil cylinder and a fixed cover. The fixed cover is sleeved on the outside of the first-level output oil cylinder and fixedly connected to the first-level output oil cylinder. The output shaft of the first-level output oil cylinder extends out of the fixed cover. It is characterized in that the output ends of the first-level output oil cylinder are respectively provided with a connecting plate and a connecting cover, the connecting cover includes an annular cover and a circular sealing plate, the end of the annular cover is integrally connected to the circular sealing plate, circular holes are evenly distributed on the circumference of the circular sealing plate, and connecting holes corresponding to the threaded holes are evenly distributed on the connecting plate. The connecting bolts pass through the connecting holes on the connecting plate and the circular holes on the circular sealing plate and are fixedly connected to the output end of the first-level output oil cylinder. The annular cover is covered on the outside of the fixed cover and is sealed and rotatably connected to the fixed cover.

[0007] The end of the fixed cover described in the utility model is connected to the annular sliding sleeve via a locking bolt. The outer edge of the annular sliding sleeve is provided with a sliding groove. A guide ring is installed in the sliding groove. The guide ring is slidably connected to the inner wall of the annular cover. The annular sliding sleeve is integrally connected to the first-level output oil cylinder.

[0008] The end of the annular sleeve of the utility model is uniformly provided with through holes in the circumferential direction, and the locking bolts pass through the through holes of the end of the annular sleeve and are connected with the screw holes provided at the end of the fixed cover.

[0015] The present invention is further described below with reference to the accompanying drawings:

[0016] As shown in the accompanying drawings, a first-level horizontal rotation mechanism of a wet spraying manipulator is provided with a first-level output oil cylinder 1 and a fixed cover 2. The fixed cover 2 is sleeved on the outside of the first-level output oil cylinder 1 and fixedly connected to the first-level output oil cylinder 1. The output shaft of the first-level output oil cylinder 1 extends out of the fixed cover 2, and is characterized in that the output ends of the first-level output oil cylinder 1 are respectively provided with connecting plates 3 and connecting covers 4, and the connecting cover 4 includes an annular cover 5 and a circular sealing plate 6. The end of the annular cover 5 is integrally connected to the circular sealing plate 6, and circular holes are evenly distributed on the circumference of the circular sealing plate 6. The connecting plate 3 is evenly distributed with connecting holes corresponding to the threaded holes. The connecting bolts 7 pass through the connecting holes on the connecting plate 3 and the circular holes on the circular sealing plate 6 and are fixedly connected to the output end of the first-level output oil cylinder 1. The annular cover 5 covers the outside of the fixed cover 2 and is sealed and rotatably connected to the fixed cover 2.

[0017] Furthermore, the end of the fixed cover 2 is connected to the annular sleeve 8 via a locking bolt 9. The outer edge of the annular sleeve 8 is provided with a slide groove 10. A guide ring is installed in the slide groove 10. The guide ring is slidably connected to the inner wall of the annular cover 5. The annular sleeve is integrally connected to the first-level output cylinder. Therefore, the annular sleeve fixes the first-level output cylinder on the fixed cover. The above-mentioned guide ring is an annular structure made of nylon and glass fiber.

[0018] Furthermore, through holes are evenly distributed on the circumferential direction of the end of the annular sleeve 8 , and the locking bolts 9 pass through the through holes on the end of the annular sleeve 8 and are connected with the screw holes on the end of the fixed cover 2 .

[0019] Furthermore, an annular sealing groove 11 is provided on the outer side of the end of the fixed cover 2 , and a sealing ring is sleeved in the sealing groove. The sealing ring and the inner wall of the annular cover 5 are in a sealed state.

[0020] Furthermore, both ends of the connecting plate 3 are vertically and integrally connected to the transverse plate 12 . The transverse plate 12 is U-shaped after being connected to the connecting plate 3 . The transverse plate 12 is connected to the secondary vertical rotation mechanism.

[0021] When installing the utility model, first, a fixed cover 2 is put on the outer side of the first-stage output oil cylinder 1, and the fixed cover 2 is fixedly connected to the first-stage output oil cylinder 1. The rear end of the fixed cover 2 is integrally connected with a flange. The rear end of the fixed cover 2 is connected to the extension arm of the mobile machinery through the flange and fixing bolts. Then the front end of the fixed cover 2 is connected to the annular sleeve 8 through the locking bolt 9, and a guide ring is installed in the slide groove 10 of the annular sleeve 8. A sealing ring is put in the annular sealing groove 11 at the front end of the fixed cover 2. The sealing ring is an elastic rubber sealing ring. The annular cover 5 and the circular sealing plate 6 are an integrated connection structure. The annular cover 5 covers the sealing ring and the guide ring. A connecting plate 3 is placed on the end of the circular sealing plate 6. The connecting hole of the connecting plate 3 corresponds to the circular hole of the circular sealing plate 6. Then the connecting bolt 7 passes through the connecting hole on the connecting plate 3 and the circular hole on the circular sealing plate 6 and is fixedly connected to the output end of the first-stage output oil cylinder 1, thereby completing the first-stage horizontal rotation mechanism and the output end of the extension arm of the mobile machinery. The secondary vertical rotation mechanism is subsequently connected to the transverse plate 12 connected to the connecting plate 3. Since the structure is provided with an integrated structure of the annular cover 5 and the circular sealing plate 6, the output end of the first-level output oil cylinder 1 is protected by the annular cover 5 and the circular sealing plate 6. Moreover, the combination of the sealing ring and the guide ring prevents external dust from entering the shaft of the output end of the first-level output oil cylinder 1, avoids the jamming phenomenon, and increases the service life of the first-level output oil cylinder 1. At the same time, since the annular cover 5 covers the outside of the fixed cover 2, when the secondary vertical rotation mechanism generates pressure on the output bearing of the first-level output oil cylinder 1, the annular cover 5 can better protect the output shaft of the first-level output oil cylinder 1, avoid all the pressure being applied to the output shaft, protect the entire first-level output oil cylinder 1, and make the structure more stable. Due to the above structure, the utility model has the advantages of simple structure, high connection strength, good protection effect, stable output, and high structural stability.
