[0028] See also Figure 1-5 The utility model provides a technical solution: a slope shotcrete thickness monitoring device, comprising two guide rails 1, two monitoring trolleys 2, a monitoring device, a traction device, and a guide rail pad 5. The two guide rails 1 are parallel to each other and are laid from top to bottom along the inclined surface of the slope on both sides of the area where concrete needs to be shotcreted on the slope. The two monitoring trolleys 2 are slidably connected to the two guide rails 1, respectively. The monitoring device comprises an infrared sensor 3, a controller, and a prompting device. The infrared sensor 3 comprises a transmitter head that transmits infrared rays and a receiver head that receives infrared rays. The transmitter head and the receiver head are respectively arranged on one of the two monitoring trolleys 2 and the two are arranged facing each other. The infrared rays emitted by the transmitter head are received by the receiver head. The infrared sensor 3 is electrically connected to the controller for When the infrared rays emitted by the transmitter are blocked, a signal is sent to the controller. The controller is electrically connected to the prompting device and is used to control the prompting device to give a prompt when receiving the signal emitted by the infrared sensor 3. The traction device includes a motor 41, two traction wires 42 and two winding drums 43. The two winding drums 43 are respectively arranged at the top of the two guide rails 1. The two traction wires 42 are respectively connected between the two winding drums 43 and the two monitoring carts 2. The motor 41 is connected to the two winding drums 43 to drive the winding drums 43 to rotate and reel in the traction wires 42. A number of guide rail pads 5 are respectively placed between the two guide rails 1 and the slope surface to raise the guide rails 1 so that the transmitter and the receiving head on the monitoring cart 2 are located at the position on the slope surface where the sprayed concrete needs to reach a thickness.

[0029] When in use, two guide rails 1 are laid from top to bottom along the inclined surface of the slope on both sides of the area where concrete needs to be sprayed on the slope, and two monitoring trolleys 2 are placed at the bottom ends of the two guide rails 1. The guide rail pads 5 are used to raise the guide rails 1 so that the transmitter and the receiving head on the monitoring trolley 2 are located at the position where the thickness of the concrete sprayed on the slope surface needs to be reached. The transmitter on one monitoring trolley 2 emits infrared rays to the receiving head on the other monitoring trolley 2 and is received by the receiving head. The construction workers spray concrete from bottom to top on the slope. When the concrete sprayed on the bottom of the slope reaches the designed thickness, the infrared rays emitted by the transmitter are blocked by the concrete, and the receiving head cannot receive the infrared rays. The infrared sensor 3 sends a signal to the controller. When the controller receives the signal sent by the infrared sensor 3, it controls the prompt device to prompt, and the construction workers When it is found that the prompt device issues a prompt, the motor 41 is started, and the motor 41 drives the two winding drums 43 to reel in the traction line 42, thereby pulling the monitoring trolley 2 upward along the guide rail 1 until the receiving head receives the infrared ray again, the infrared sensor 3 stops sending signals, and the prompt device stops prompting. The construction personnel then spray concrete at that height position, and repeat this process until the entire slope surface sprayed concrete reaches the designed thickness. Of course, at the beginning, the two monitoring trolleys 2 can be placed at the top of the two guide rails 1, and the construction personnel spray concrete on the slope from top to bottom. When the concrete at the top of the slope reaches the designed thickness, the motor 41 is controlled to reverse and drive the two winding drums 43 to release the traction line 42, so that the monitoring trolley 2 slides down due to gravity for monitoring, thereby realizing the monitoring of the thickness of the slope sprayed concrete during construction.

[0030] Compared with the traditional manual measurement method, the utility model uses an infrared sensor 3, a controller and a prompting device to perform real-time thickness monitoring and prompting, which can clearly determine whether the concrete spraying thickness meets the standard, ensure the quality of the concrete support surface, and effectively reduce the material waste caused by over-squareness.

[0031] Furthermore, in order to prevent the monitoring trolley 2 from shifting or tilting on the guide rail 1, which would cause the transmitter and receiver heads of the infrared sensors 3 on the two monitoring trolleys 2 to be misaligned, the monitoring trolley 2 is provided with wheels 21, and the surface of the guide rail 1 is provided with grooves 11 extending along the length direction of the guide rail 1. The wheels 21 are rollingly connected in the grooves 11, and the grooves 11 are used to constrain the wheels 21 of the monitoring trolley 2 so that it cannot shift or tilt, and the monitoring trolley 2 equipped with wheels 21 is easier to move on the track 1.

[0032] Furthermore, blocking blocks 12 for blocking the two ends of the groove 11 are provided at both ends of the guide rail 1 to prevent the monitoring trolley 2 from escaping from the guide rail 1 .

[0033] Furthermore, a protection box 6 is provided on the monitoring trolley 2, and the infrared sensor 3 is arranged in the protection box 6. The protection box 6 is provided with an opening 61 for the transmitter to transmit infrared rays and the receiver to receive infrared rays, so as to protect the infrared sensor 3 and prevent the sprayed concrete from covering the infrared sensor 3 and causing damage.

[0034] Further, the guide rail 1 includes a front end guide rail 7, a plurality of middle guide rails 8 and a rear end guide rail 9, the front end guide rail 7, the plurality of middle guide rails 8 and the rear end guide rail 9 are sequentially connected end to end to form the guide rail 1, the groove 11 is provided on the surface of the front end guide rail 7, the plurality of middle guide rails 8 and the rear end guide rail 9, the blocking block 12 at one end of the guide rail 1 is provided at one end of the front end guide rail 7, the front end guide rail 7 is provided with a front end latch 71 at the other end, the middle guide rail 8 is provided with a middle slot 81 at one end, the middle guide rail 8 is provided with a middle latch 82 at the other end, and the blocking block 12 at the other end of the guide rail 1 is provided One end of the rear end guide rail 9 and the other end of the rear end guide rail 9 are provided with a rear end slot 91, the front end pin 71 of the front end guide rail 7 can be inserted in the middle slot 81 of the middle guide rail 8 or the rear end slot 91 of the rear end guide rail 9, and the middle pin 82 of the middle guide rail 8 can be inserted in the middle slot 81 of another middle guide rail 8 or the rear end slot 91 of the rear end guide rail 9 to connect the front end guide rail 7, several middle guide rails 8, and the rear end guide rail 9 end to end, so that the length of the track 1 can be adjusted according to the slope length of the slope. When the track 1 needs to be lengthened or shortened, the middle guide rail 8 can be increased or decreased.

[0035] Furthermore, the monitoring trolley 2 is a trolley with a hollow frame structure welded with metal pipes, which ensures structural stability while the porous design facilitates the installation and modification of various parts.

[0036] Furthermore, the prompting device is a display and / or an indicator light and / or a buzzer, so that the construction personnel can be prompted by the buzzer making a sound, the indicator light emitting light, the display showing a pattern, text, etc.

[0037] Furthermore, the controller is electrically connected to the motor 41 and is used to control the motor 41 to rotate for a certain period of time when receiving a signal from the infrared sensor 3. Therefore, when the shotcrete on the slope at a certain height position reaches a certain thickness, the controller controls the prompt device to prompt and automatically controls the motor 41 to rotate for a certain period of time, so that the winding drum 43 reels or releases the traction line 42, so that the monitoring vehicle 2 reaches the next height position for monitoring. There is no need for manual operation of the motor 41, which is more efficient.

[0038] Furthermore, the controller can be implemented by a PLC programmable controller.

[0039] Furthermore, the indicator light has two changeable colors to facilitate prompting construction personnel. For example, it continuously displays red when the infrared sensor 3 does not detect concrete, and it displays green when the infrared sensor 3 detects concrete, indicating that the shotcrete reaches the designed thickness.
