Description

Technical Field

[0001] This utility model relates to the field of shotcrete pipe processing technology, specifically to an automated production device for high-strength shotcrete pipes. Background Technology

[0002] In many industries such as construction, mining, and chemical engineering, shotcreting is an important construction process. Shotcreting requires shotcreting pipes, and the cutting process is extremely critical in the production of shotcreting pipes. The cutting of rigid shotcreting pipes is mostly done manually, which relies entirely on the manual operation skills and experience of workers, making it difficult to ensure the flatness and perpendicularity of the cut.

[0003] For example, a hose production device with authorization announcement number "CN 208034747U" uses a roller to press the hose as it moves within a V-groove. The roller reduces friction between the hose and the V-groove, and the cutting position can be accurately determined based on the markings on both sides of the V-groove. This eliminates the need for manual hose movement, and the movement distance is precisely controlled, reducing worker workload and improving cutting efficiency. Traditional methods for cutting rigid sprayed pipes have many drawbacks. In the traditional manual operation mode, workers must hold the cutting tool to cut the sprayed pipe, which is highly dependent on their experience and physical strength. Furthermore, the lack of stable clamping makes the sprayed pipe prone to shaking during cutting, making it difficult to guarantee cutting accuracy. Each cut also requires tedious preparation work, including measuring the cutting length and adjusting the cutting angle, which limits the cutting output per unit time. Utility Model Content

The rotation shaft of the second bevel gear is fixedly connected to a cam. The rotation shaft of the cam is rotatably connected to the second housing through bearings. The outer wall of the cam abuts against the clamping block. Both sides of the inner wall of the clamping block are slidably connected to a second slide rod. The outer wall of the second slide rod is sleeved with a spring. Both ends of the spring are fixedly connected to the clamping block and the second housing, respectively.

[0010] Preferably, the outer wall of the clamping block is slidably connected to the second housing, and both ends of the second slide rod are fixedly connected to the second housing.

[0011] Preferably, the first hydraulic cylinder is fixedly connected to the left and right sides of the second hydraulic cylinder, and a pressure plate is fixedly connected to the output end of the first hydraulic cylinder.

[0012] The present invention proposes an automated production device for high-strength shotcrete pipes, the advantages of which are as follows: Through the cooperation of the shotcrete pipe clamping structure and the shotcrete pipe feeding structure, the output shaft of the first servo motor rotates to drive the disc to rotate, the disc rotation drives the chuck and cylinder to rotate, when the disc is no longer in contact with the grooved wheel, the grooved wheel is no longer limited, when the cylinder rotates into the groove processed by the grooved wheel, the rotation of the cylinder causes the grooved wheel to rotate, the rotation of the grooved wheel drives the gear to rotate, the gear rotation drives the rack to slide to the right on the first slide rod, thereby moving the shotcrete pipe to the right, the output shaft of the second servo motor rotates to drive the disc to rotate, the cylinder rotation drives the rack to slide to the right on the first slide rod, thereby moving the shotcrete pipe to the right, the output shaft of the second servo motor rotates to drive the rack to rotate, the cylinder rotation drives ...

At this time, the spring is compressed, so the spring always has a rebound force that keeps the clamping blocks in contact with the cams. An arc-shaped rubber block is installed at the position where the clamping blocks contact the shotcrete pipe. Until the clamping blocks are pressed tightly against the shotcrete pipe, the shotcrete pipe is fixed, reducing the shaking of the shotcrete pipe during movement and avoiding complicated preparation work for the operators.

[0029] Working principle:

[0030] Automated production of high-strength shotcrete pipes: The cutting process is extremely critical in the production of shotcrete pipes.

[0031] Clamping of the shotcrete pipe:

[0032] Place the high-strength, rigid shotcrete pipe that needs to be cut into the groove at the upper end of the base 1, with the left side of the shotcrete pipe positioned between the two clamping blocks 506. Connect the external power supply to the second servo motor 501 and start the second servo motor 501. The output shaft of the second servo motor 501 rotates, driving the round rod 502 to rotate (e.g., Figure 4 The rotation of the round rod 502 drives the two first bevel gears 503 to rotate. The rotation of the first bevel gears 503 causes the two second bevel gears 504 to rotate. The two second bevel gears 504 rotate in opposite directions. The rotation of the second bevel gears 504 drives the two cams 505 to rotate. The rotation of the cams 505 causes the two clamping blocks 506 to slide relative to each other on the second slide rod 507. At this time, the spring 508 is compressed, so the spring 508 always has a rebound force that keeps the clamping blocks 506 in contact with the cams 505. An arc-shaped rubber block is installed at the position where the clamping blocks 506 contact the spray pipe. Until the clamping blocks 506 and the spray pipe are pressed tightly together, the spray pipe is fixed and the second servo motor 501 is turned off.

[0033] Movement of the shotcrete pipe:

[0034] When the external power supply of the first servo motor 301 is connected and the first servo motor 301 is started, the output shaft of the first servo motor 301 rotates, driving the disk 302 to rotate (e.g. Figure 6The rotation of disc 302 drives chuck 303 and cylinder 304 to rotate. When disc 302 is no longer in contact with grooved wheel 305, it no longer limits grooved wheel 305. When cylinder 304 rotates into the groove processed by grooved wheel 305, the rotation of cylinder 304 causes grooved wheel 305 to rotate. The rotation of grooved wheel 305 drives gear 306 to rotate. The rotation of gear 306 drives rack 307 to slide to the right on first slide rod 308, thereby moving the shotcrete pipe to the right. When cylinder 304 disengages from the groove processed by grooved wheel 305, chuck 303 begins to contact grooved wheel 305, limiting grooved wheel 305 and preventing it from rotating. To further explain, cylinder 304 ensures that grooved wheel 305 rotates at the same angle each time, thus ensuring that the shotcrete pipe moves the same length and that the cutting size is consistent each time. At this time, two first hydraulic cylinders 7 are activated. The movement of two first hydraulic cylinders 7 drives pressure plate 8 to move downward, thereby fixing the shotcrete pipe and connecting the circuit. When the external power supply of the third servo motor 10 is connected, the third servo motor 10 is started. The output shaft of the third servo motor 10 rotates, driving the cutting blade 11 to rotate. The second hydraulic cylinder 9 is started, and the second hydraulic cylinder 9 drives the cutting blade 11 to rotate while moving downward, thereby cutting the shotcrete pipe. After the cutting is completed, the two hydraulic cylinders are reset, and the cut shotcrete pipe is taken out. The shotcrete pipe can be continuously cut in the above way. There is no need to manually adjust the shotcrete pipe during the cutting process, thereby achieving the purpose of automated production of shotcrete pipe. After the shotcrete pipe is cut, the second servo motor 501 is started. The output shaft of the second servo motor 501 reverses, causing the two clamps 506 to move away from the shotcrete pipe. The second servo motor 501 is turned off, and the first servo motor 301 is started. The output shaft of the first servo motor 301 reverses, causing the two clamps 506 to return to their original positions. The first servo motor 301 is turned off for the next use, thus completing the working process of the high-strength shotcrete pipe automated production device.
