[0002] As a tensile member that penetrates deep into the stratum, the anchor rod is connected to the engineering structure at one end and penetrates deep into the stratum at the other end. The anchor rod is not only used in mines, but also in engineering technology to reinforce the slopes, tunnels, and dam bodies. After the tunnel blasting construction process, in order to ensure the anchoring effect of the anchor rod and avoid damage to the anchor rod during the blasting process, non-destructive testing instruments are often used to perform non-destructive testing on the anchor rod after the blasting.

[0003] However, when the existing non-destructive testing instrument is used, in order to ensure the reinforcement effect of the anchor rods on the tunnel, more anchor rods are often installed during the tunnel construction process. Similarly, in order to ensure the construction quality of the tunnel, each anchor rod needs to be tested during the test. However, when the existing non-destructive testing instrument is used, the staff often holds the testing instrument with one hand and operates the testing instrument with the other hand, while the other staff tests the anchor rod. Since the testing project is large, the staff needs to hold the testing instrument for a long time, which is very inconvenient and reduces the use effect of the non-destructive testing instrument.

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a device for measuring the blasting damage of tunnel anchor bolts, comprising a non-destructive testing instrument body 1, the upper end of the non-destructive testing instrument body 1 is fixedly connected to a line storage box 2, and the surface of the line storage box 2 is fixedly connected to a hanging rope 3, and the end of the non-destructive testing instrument body 1 away from the line storage box 2 is fixedly connected to two arc-shaped stickers 5, so that the arc-shaped setting of the stickers 5 allows the stickers 5 to fit more closely with the user's abdomen, thereby ensuring the stability of subsequent fixation of the device, and the opposite ends of the two stickers 5 are fixedly connected with a binding rope 6, so that the staff can tie the binding rope 6 when using it, and bind the device as a whole to the user's abdomen, and at the same time put the hanging rope 3 around the neck, so that the device is suspended at the user's abdomen, thereby freeing the staff's hands, thereby avoiding the situation that the staff needs to hold the device with one hand continuously and operate with one hand when detecting the anchor bolt, thereby reducing the labor intensity of the staff and improving the use effect of the device.

[0025] Secondly, a detection box 7 is slidably connected to the bottom of the line storage box 2. The detection box 7 is open, and a knocking rod 10 penetrating the surface of the detection box 7 is slidably connected to the surface of the detection box 7. The cross-section of the knocking rod 10 is T-shaped, which is used to knock on the anchor rod. At the same time, the T-shaped knocking rod 10 is convenient for the staff to pull the knocking rod 10. A spring 9 is movably sleeved on the surface of the knocking rod 10. The two ends of the spring 9 are respectively fixedly connected to the surface of the knocking rod 10 and the surface of the detection box 7, so as to reset the knocking rod 10.

[0026] A bellows 4 is fixedly connected to the surface of the line storage box 2, and one end of the bellows 4 away from the line storage box 2 is fixedly connected to the surface of the detection box 7. The bellows 4 is made of nylon, which is soft and can be bent, thereby avoiding the situation where the line storage box 2 and the detection box 7 cannot be separated when they are not in the same horizontal plane, thereby ensuring the smooth operation of the device.

[0027] Furthermore, the line storage box 2 is rotatably connected to a winding roller 11, and a transmission line 13 is wound on the surface of the winding roller 11. The transmission line 13 is located inside the corrugated tube 4, and the two ends of the transmission line 13 are respectively fixedly connected to the interior of the non-destructive testing instrument body 1 and the interior of the line storage box 2. One end of the transmission line 13 located inside the line storage box 2 is fixedly connected to a detection head, and a magnet is provided on the detection head, which can be directly adsorbed on the anchor rod. This is a technology known to people in this field. At the same time, the detection head and the knocking rod 10 are located in the same vertical plane in the line storage box 2, thereby ensuring that the knocking rod 10 is in contact with the anchor rod while the detection head is adsorbed on the anchor rod, and the distance between the detection head and the anchor rod is between one and three centimeters, thereby avoiding the situation where the knocking rod 10 does not contact the anchor rod due to the large distance between the detection head and the knocking rod 10 when the detection head is adsorbed on the anchor rod, thereby ensuring the normal detection of the anchor rod by the device.

[0028] Furthermore, the end of the transmission line 13 close to the nondestructive testing instrument body 1 is not in a straight state, and the transmission line 13 is still scattered in the line storage box 2 with a certain length, thereby avoiding the situation that when the winding roller 11 is rotating, the winding roller 11 relaxes the end of the transmission line 13 close to the testing box 7, and pulls the end of the transmission line 13 close to the nondestructive testing instrument body 1, resulting in the transmission line 13 being separated from the nondestructive testing instrument body 1, thereby ensuring the stability of the connection between the transmission line 13 and the nondestructive testing instrument body 1.

[0029] A torsion spring 12 is movably sleeved on the surface of the winding roller 11, and two ends of the torsion spring 12 are respectively fixedly connected to the surface of the winding roller 11 and the interior of the line storage box 2 to drive the transmission line 13 to reset.

[0030] Furthermore, threaded rods 8 are rotatably connected to both sides of the detection box 7, and two clamps 14 are slidably connected inside the detection box 7. The opposite sides of the two clamps 14 are arc-shaped, so that the clamps 14 can fit the anchor rod more closely, ensuring the fixing effect of the device on the anchor rod. The opposite ends of the two threaded rods 8 are rotatably connected to the opposite sides of the two clamps 14 respectively, and the opposite sides of the two clamps 14 are fixedly connected to rubber pads 15. Through the setting of the rubber pads 15, the anchor rod and the clamps 14 are in flexible contact, so that when the device knocks and vibrates the anchor rod, the device can absorb and buffer the lateral vibration of the protruding end of the anchor rod, thereby reducing the influence of the lateral vibration of the protruding end of the anchor rod on the detection result of the device when the device detects the anchor rod, thereby improving the accuracy of the detection result of the device.

[0031] Furthermore, when the anchor rod is inspected after blasting, the inspection box 7 is removed from the line storage box 2, and then the corrugated tube 4 is stretched, and the transmission line 13 is stretched at the same time, so that the winding roller 11 rotates in the line storage box 2, and the torsion spring 12 is twisted, and then the inspection box 7 is inserted into the anchor rod, and then the two threaded rods 8 are rotated at the same time, driving the two clamping plates 14 to clamp and fix the anchor rod, and then the staff can pull the knocking rod 10 to stretch the spring 9, and then stop pulling the knocking rod 10, and under the elastic force of the spring 9, the knocking rod 10 knocks on the anchor rod, so as to prevent the anchor rod from being damaged. At this time, the vibration data generated by the anchor rod is transmitted to the non-destructive testing instrument body 1 through the detection head and the transmission line 13, so that the staff can understand the detection data of the anchor rod on the non-destructive testing instrument body 1. After the detection is completed, the detection box 7 is installed on the line storage box 2 again, and then under the elastic force of the torsion spring 12, the winding roller 11 is reversed to reel up the transmission line 13, so that after the device is used, the staff does not need to organize the line and other tools to organize the next anchor rod, which is convenient for the staff to use, and has high promotion value and practicality.

[0032] Working principle: When inspecting the anchor rod, remove the inspection box 7 from the line storage box 2, insert the inspection box 7 on the anchor rod, and then rotate the two threaded rods 8 at the same time, driving the two clamps 14 to clamp and fix the anchor rod. Then the staff can pull the knocking rod 10 to stretch the spring 9, and then stop pulling the knocking rod 10. Under the elastic force of the spring 9, the knocking rod 10 knocks on the anchor rod. At this time, the vibration data generated by the anchor rod is transmitted to the non-destructive testing instrument body 1 through the detection head and the transmission line 13, so that the staff can understand the detection data of the anchor rod on the non-destructive testing instrument body 1.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
