[0002] When making cement culverts, the steel cage needs to be fastened in advance, and a large amount of steel bars are needed at this time. In order to ensure the quality of the culvert, it is usually necessary to test the straightness of the steel bars. If the steel bars are found to be bent, they need to be straightened on a steel bar straightening machine.

[0003] The guide wheels of the steel bar straightening machine are divided into a fixed wheel and a moving wheel. The push spring equipped on the surface of the moving wheel will experience a decrease in elastic force after long-term use. At this time, the push spring needs to be adjusted. In order to further improve the timeliness of the push spring adjustment time and the accuracy of the adjustment force, a guide wheel adjustment structure for a culvert steel bar straightening machine is needed. The elastic force of the push spring is monitored in real time through a sensor, and the motor is controlled to drive the push rod to adjust the actual length of the push spring, thereby improving the timeliness and accuracy of the push spring adjustment.

[0024] Embodiment 2:

[0025] Figure 1-4The utility model shows a guide wheel adjustment structure for a culvert steel bar straightening machine according to an embodiment of the present invention, which includes a carrier plate 1: a slide seat 2 is slidably installed on the inner wall of the carrier plate 1, and a push spring 3 and a balance spring 4 are respectively arranged on the left and right sides of the slide seat 2, a rectangular plate 5 is fixedly installed on the surface of the carrier plate 1, and a moving wheel 6 and a fixed wheel 7 are rotatably connected to the surfaces of the slide seat 2 and the carrier plate 1 respectively through a rotating shaft, a strip plate 8 is welded on the surface of the rectangular plate 5, and a motor 9 is fixedly installed on the bottom of the strip plate 8 by bolts, and the output shaft of the motor 9 is fixedly connected to a threaded rod 10 through a flange, and a threaded sleeve 11 is threadedly connected to the surface of the threaded rod 10, and the threaded sleeve 11 is slidably connected to the rectangular plate 5, and the thread The end of the sleeve 11 passes through the rectangular plate 5 and is fixed with a pressure sensor 12 by bolts. A sleeve block 13 is fixedly installed on the surface of the pressure sensor 12. A controller 16 is fixedly installed on the surface of the strip plate 8 by bolts. The pressure sensor 12 and the controller 16 are electrically connected through a wire. A pressure block 17 is integrally formed on the surface of the threaded sleeve 11. A pressure alarm 18 is fixedly installed on the surface of the strip plate 8.

[0026] Working principle: When the utility model is used, the user monitors the elastic force of the push spring 3 squeezing the sleeve block 13 through the pressure sensor 12. When the elastic force of the push spring 3 is insufficient, the pressure sensor 12 transmits a signal to the controller 16 to control the motor 9 to start, so that the motor 9 drives the threaded sleeve 11 to move through the threaded rod 10, and then the threaded sleeve 11 drives the push spring 3 to compress and deform through the pressure sensor 12 and the sleeve block 13. At this time, the pressure sensor 12 detects that the thrust of the push spring 3 squeezing the sleeve block 13 is within the normal range and transmits the signal to the controller 16, so that the controller 16 controls the motor 9 to stop running. After the threaded sleeve 11 travels a certain distance, the threaded sleeve 11 presses the pressing alarm 18 through the pressure block 17 and causes the latter to alarm, so that the staff can replace the sleeve block 13 in time, realizes real-time monitoring of the elastic force of the push spring through the sensor, and controls the motor to drive the push rod to adjust the actual length of the push spring, thereby improving the timeliness and accuracy of the push spring adjustment.

[0027] To sum up: the guide wheel adjustment structure of the culvert steel bar straightening machine monitors the elastic force of the push spring 3 squeezing the sleeve block 13 through the pressure sensor 12. When the elastic force of the push spring 3 is insufficient, the pressure sensor 12 transmits a signal to the controller 16 to control the motor 9 to start, so that the motor 9 drives the threaded sleeve 11 to move through the threaded rod 10, and then the threaded sleeve 11 drives the push spring 3 to deform through the pressure sensor 12 and the sleeve block 13, so as to achieve real-time monitoring of the elastic force of the push spring through the sensor, and control the motor to drive the push rod to adjust the actual length of the push spring, thereby improving the timeliness and accuracy of the push spring adjustment.
