Description

Technical Field

[0001] The present invention relates to the technical field of radar detection, and in particular to a portable geological radar measuring device. Background Art

[0002] Geological radar measurement is a non-destructive testing technology that uses high-frequency electromagnetic pulse waves to penetrate underground media and detect underground structures, layers and abnormal bodies based on the time, amplitude and waveform changes of the reflected pulse waves. Geological radar technology can be used to penetrate the primary lining of the tunnel without destruction to detect the geological conditions and structural integrity behind it, helping to identify cavities, water accumulation or other abnormal structures.

[0003] At present, when measuring the primary lining of a tunnel, technical operators first place a lifting platform on a mobile platform, such as a trolley or a special tunnel inspection vehicle, and then install the geological radar on the lifting platform. Then, they push or drive the mobile platform equipped with the geological radar along a predetermined path, so that the geological radar continuously scans the inner wall of the tunnel. The on-site deployment is relatively troublesome, and ordinary geological radars do not have telescopic or folding functions, making it difficult to adapt to the complex and changeable working conditions in the tunnel and inconvenient to carry.

[0004] In addition, when using the above method for detection, multi-point measurements must be performed according to the length and shape of the tunnel and the planned detection path to ensure that all key areas are covered. The inner wall of the tunnel is an arched surface, so the operator is required to constantly adjust the angle of the geological radar on the lifting platform, which is cumbersome and unsafe to operate.

[0005] Based on the above situation, the present invention proposes a portable geological radar measurement device. Summary of the invention

[0006] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a portable geological radar measurement device.

[0008] Furthermore, it also includes a slide, which is slidably connected to the box body, and the left and right sides of the slide both penetrate the box body. The micro hydraulic telescopic arm is provided with a curved surface and a flat surface, the cover plate is fixedly connected with symmetrically distributed protrusions, and symmetrically distributed torsion springs are connected between the cover plate and the box body, and the protrusions are squeezed and matched with the slide.

[0009] Furthermore, it also includes symmetrically distributed slides, two front-to-back symmetrical slides are slidably provided on the left and right sides of the box body, and the slides are provided with upper inclined grooves and lower inclined grooves. The slides are slidably matched with the slide frame through the upper inclined grooves, and guide plates are slidably connected between the two slides on the left and between the two slides on the right through the lower inclined grooves. Two front-to-back symmetrical support rods are slidably connected on the left and right sides of the box body, and the four support rods are slidably matched with adjacent guide plates.

[0010] Furthermore, it also includes a bracket for limiting the slide, the bracket is slidably connected to the right side of the box, a tension spring is connected between the bracket and the box, the bracket is provided with arc surface two, the arc surface two is arranged corresponding to the position of the slide, and the bracket is in contact with the micro hydraulic telescopic arm.

[0011] Furthermore, it also includes a plurality of symmetrically distributed sliders, the sliders are slidably connected to the box body, a fourth spring is connected between the sliders and the box body, and the sliders are arranged corresponding to the positions of the moving frame.

[0012] Furthermore, the sliding block is configured to be in the shape of an obtuse triangle.

[0013] The beneficial effects are as follows: the present invention drives the movable frame to slide to the left to the middle position of the box body through the second spring, thereby preventing the micro hydraulic telescopic arm from working on the right side and causing the device to be unbalanced, thereby improving the stability of the equipment during operation, while taking into account the integrated storage of the micro hydraulic telescopic arm and the geological radar detector. In this way, the equipment can be retracted, folded and quickly extended, which is easy to carry and easy to operate. It not only reduces the space required for storage and transportation, but also can be quickly deployed on site, thereby improving work efficiency, while reducing the safety risks of workers in the special environment of the tunnel and improving the safety factor of the entire operation.

[0014] The present invention continuously controls and adjusts the output shaft of the motor to rotate clockwise or counterclockwise to the required angle, so that the geological radar detector can conveniently perform multi-point detection on the primary lining of the tunnel and can adapt to the measurement needs of different angles in the tunnel. This means that in a complex and changeable underground environment, all-round geological detection can be completed without frequent movement or repositioning of the instrument, thereby enhancing the flexibility and accuracy of the measurement.

[0015] In the process of the micro hydraulic telescopic arm rotating upward, the slide frame pushes the cover plate upward through the convex block to achieve the effect of automatic cover opening without manual cover opening.

[0016] When the cover is opened, the slide frame is used to drive the support rod to slide obliquely downward along the box body, so that the support rod can be supported on the tunnel inspection vehicle in an eight-shaped shape, thereby improving the stability of the entire device placed on the tunnel inspection vehicle.

[0017] The present invention limits the slide by means of a clamping bracket, and the clamping bracket releases the limit on the slide only when the micro-hydraulic telescopic arm is completely and horizontally retracted into the box body, thereby achieving the effect of delaying the retraction of the support rod, avoiding the situation in which the support rod begins to retract when the micro-hydraulic telescopic arm has not yet been completely reset, thereby avoiding affecting the stability of the equipment in the working state.

[0018] The present invention decelerates the moving frame by means of a slider, so as to prevent the moving frame from sliding too fast, resulting in the moving frame being blocked by a box body and stopping suddenly, and the vibration generated is transmitted to the geological radar detector, thereby damaging the geological radar detector.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0030] A portable geological radar measuring device, combined with Figure 1 To Attachment Figure 3 , including a box 1, it should be noted that, Figure 1In the figure, a is left, b is right, c is front, and d is back. The top of the box body 1 is rotatably connected to two front-to-back symmetrical cover plates 2. The lower inner part of the box body 1 is slidably connected to a moving frame 3 along the left-right direction. The moving frame 3 is rotatably connected to a micro hydraulic telescopic arm 4, which can be wirelessly controlled to extend and retract by an external remote controller. A geological radar detector 5 is slidably connected to the side of the micro hydraulic telescopic arm 4 away from the moving frame 3. A first spring 6 symmetrically distributed up and down is connected between the micro hydraulic telescopic arm 4 and the geological radar detector 5. A motor 7 is fixedly connected to the front side of the moving frame 3. The output shaft of the motor 7 can be wirelessly controlled to rotate by a remote controller. The output shaft of the motor 7 is connected to the micro hydraulic telescopic arm 4 is fixedly connected, a second spring 8 symmetrically distributed front and back is connected between the moving frame 3 and the box body 1, two baffles 9 symmetrically distributed front and back are slidably connected in the box body 1 along the up and down direction, the left and right sides of the bottom of the baffle 9 are set as planes, and the middle is set as an inclined surface, the side of the micro hydraulic telescopic arm 4 close to the moving frame 3 is fixedly connected with a guide rod 901 symmetrically distributed front and back, the baffle 9 is provided with an arc groove and a transverse groove, the upper end of the arc groove is connected with the transverse groove, the guide rod 901 is slidably matched with the adjacent baffle 9, a third spring 10 is connected between the baffle 9 and the box body 1, and the side of the moving frame 3 close to the inclined surface of the baffle 9 is rotatably connected with a roller 11 symmetrically distributed front and back, and the roller 11 is squeezed and matched with the inclined surface of the adjacent baffle 9.

[0031] When using the device to measure the quality of the initial lining of a tunnel, first open the cover plate 2, then control the output shaft of the motor 7 to drive the micro hydraulic telescopic arm 4 to rotate upward by ninety degrees to a vertical state, and the geological radar detector 5 and the first spring 6 rotate together with the micro hydraulic telescopic arm 4;

[0032] During the upward rotation of the micro hydraulic telescopic arm 4, the micro hydraulic telescopic arm 4 drives the guide rod 901 to rotate synchronously. The guide rod 901 first slides along the arc groove on the baffle 9. When the guide rod 901 moves into the transverse groove on the baffle 9, the guide rod 901 continues to rotate to drive the baffle 9 to slide upward. At the same time, the third spring 10 is compressed so that the inclined surface at the bottom of the baffle 9 no longer squeezes the roller 11. At this time, the second spring 8 in the compressed state is reset to drive the mobile frame 3 to slide left to the middle position of the box body 1.

[0033] Afterwards, the device is placed on a movable tunnel inspection vehicle, so that the device is moved to the middle of the entrance of the tunnel primary lining, and then the micro hydraulic telescopic arm 4 is wirelessly controlled to extend through the remote control, thereby driving the geological radar detector 5 to move upward to contact the inner wall of the tunnel primary lining. The first spring 6 can prevent the geological radar detector 5 from being squeezed and damaged by the micro hydraulic telescopic arm 4, and then the whole device is driven to move horizontally to the exit of the tunnel primary lining by the tunnel inspection vehicle. In this process, the geological radar detector 5 is turned on to complete the detection of the center line of the tunnel primary lining;

[0034] Subsequently, the output shaft of the motor 7 is continuously controlled and adjusted to rotate clockwise or counterclockwise to a desired angle, and then the entire device is driven by the tunnel inspection vehicle to translate toward the entrance or exit of the tunnel primary lining, and this is repeated to achieve multi-point detection of the tunnel primary lining;

[0035] After the detection is completed, the micro hydraulic telescopic arm 4 is controlled to shorten, and then the output shaft of the motor 7 is controlled to drive the micro hydraulic telescopic arm 4 to rotate downward, and the geological radar detector 5 and the first spring 6 rotate together with the micro hydraulic telescopic arm 4;

[0036] During the downward rotation of the micro-hydraulic telescopic arm 4, the micro-hydraulic telescopic arm 4 drives the guide rod 901 to rotate synchronously. The guide rod 901 first pushes the baffle 9 to slide downward, and the third spring 10 gradually resets. During the downward sliding of the baffle 9, the inclined extrusion roller 11 moves to the right, thereby driving the movable frame 3 to slide to the right, and the second spring 8 is compressed. In this way, the micro-hydraulic telescopic arm 4 can drive the geological radar detector 5 and the first spring 6 to continue to rotate to a horizontal state to be stored in the box body 1. After folding and storing, close the cover 2 and then take away the equipment.

[0037] In summary, the present invention drives the movable frame 3 to slide to the left to the middle position of the box body 1 by resetting the second spring 8 in a compressed state, thereby preventing the micro hydraulic telescopic arm 4 from working on the right side and making the device unbalanced, thereby improving the stability of the equipment during operation, and at the same time taking into account the integrated storage of the micro hydraulic telescopic arm 4 and the geological radar detector 5. In this way, the equipment itself can be retracted, folded and quickly extended, which is easy to carry and easy to operate. It not only reduces the space required for storage and transportation, but also can be quickly deployed on site, thereby improving work efficiency, while reducing the physical labor and safety risks of workers in special environments such as tunnels, thereby improving the safety factor of the entire operation.

[0038] By continuously controlling and adjusting the output shaft of the motor 7 to rotate clockwise or counterclockwise to the required angle, the geological radar detector 5 can conveniently perform multi-point detection on the primary lining of the tunnel and can adapt to the measurement needs of different angles in the tunnel. This means that in a complex and changeable underground environment, all-round geological detection can be completed without frequent movement or repositioning of the instrument, thereby enhancing the flexibility and accuracy of the measurement.

[0039] Combined with Figure 4 To Attachment Figure 5The portable geological radar measuring equipment also includes a slide 12, which is slidably connected to the box body 1 along the up and down directions. The left and right sides of the slide 12 penetrate the box body 1. When the micro-hydraulic telescopic arm 4 is horizontally retracted into the box body 1, the micro-hydraulic telescopic arm 4 contacts the bottom of the slide 12 through the flat surface 123, and the micro-hydraulic telescopic arm 4 is squeezed and matched with the slide 12 through the arc surface 122, so that when the micro-hydraulic telescopic arm 4 rotates upward, the slide 12 can slide upward, and the bottom of the cover plate 2 is fixedly connected with left and right symmetrically distributed protrusions 121, and the protrusions 121 are squeezed and matched with the slide 12, so that when the slide 12 slides upward, the slide 12 pushes the cover plate 2 upward through the protrusions 121, and left and right symmetrically distributed torsion springs 13 are connected between the cover plate 2 and the box body 1.

[0040] During the upward rotation of the micro hydraulic telescopic arm 4, the contact between the micro hydraulic telescopic arm 4 and the slide 12 will transition from the flat surface 123 to the curved surface 122. During the transition from the flat surface 123 to the curved surface 122, the micro hydraulic telescopic arm 4 squeezes the slide 12 through the curved surface 122 to slide upward, and the slide 12 pushes the cover plate 2 upward through the protrusion 121, so that the torsion spring 13 is deformed. In this way, the effect of automatic opening of the cover is achieved without manual opening. When the cover plate 2 is pushed open by the slide 12, the micro hydraulic telescopic arm 4 Continuing to rotate upward will no longer drive the slide 12 to move further upward through the arc surface 122; when the micro hydraulic telescopic arm 4 rotates downward and is retracted into the box body 1, the contact point between the micro hydraulic telescopic arm 4 and the slide 12 will transition from the arc surface 122 to the flat surface 123, and the micro hydraulic telescopic arm 4 will no longer squeeze the slide 12. Under the action of the slide 12's own gravity and the reset of the torsion spring 13 so that the protrusion 121 squeezes the slide 12, the slide 12 automatically slides downward, and the torsion spring 13 gradually resets to drive the cover plate 2 to automatically close.

[0041] Combined with Figure 6 To Attachment Figure 7 The portable geological radar measuring equipment also includes a symmetrically distributed slide 14. Two front-to-back symmetrical slides 14 are arranged on the left and right sides of the box body 1. The slide 14 is slidably connected to the box body 1 along the front-to-back direction. The slide 14 is provided with an upper oblique groove and a lower oblique groove. The slide 14 slides with the slide 12 through the upper oblique groove. The slide 12 slides upward to squeeze the two adjacent slides 14 close to each other. A guide plate 15 is slidably connected between the two slides 14 on the left and between the two slides 14 on the right through the lower oblique groove. The two adjacent slides 14 are close to each other to squeeze the guide plate 15 to move downward. Two front-to-back symmetrically distributed support rods 16 are slidably connected on the left and right sides of the box body 1. The four support rods 16 are slidably matched with the adjacent guide plates 15. The guide plate 15 moves downward to drive the support rods 16 to slide obliquely downward.

[0042] When the slide 12 slides upward, the two adjacent slide plates 14 are squeezed closer to each other through the upper inclined groove, and the slide plate 14 then squeezes the guide plate 15 downward through the lower inclined groove, thereby driving the support rod 16 to slide obliquely downward along the box body 1, and at the same time, the two adjacent support rods 16 are separated from each other, so that the support rod 16 can be supported on the tunnel inspection vehicle in an eight-shaped shape, thereby improving the stability of the entire device placed on the tunnel inspection vehicle;

[0043] When the slide 12 slides downward, the two adjacent slide plates 14 are squeezed away from each other through the upper inclined groove, and the slide plate 14 then squeezes the guide plate 15 upward through the lower inclined groove, thereby driving the support rod 16 to slide obliquely upward along the box body 1, and at the same time, the two adjacent support rods 16 approach each other, so that the support rod 16 is stored on the box body 1.

[0044] Combined with Figure 8 The portable geological radar measuring equipment also includes a bracket 17 for limiting the slide 12. The bracket 17 is slidably connected to the right side of the box body 1 along the left and right directions. A tension spring 18 symmetrically distributed front and back is connected between the bracket 17 and the box body 1. An arc surface 171 is provided on the bracket 17. The arc surface 171 is arranged corresponding to the position of the slide 12. The left end surface of the lower part of the bracket 17 is in contact with the micro hydraulic telescopic arm 4. When the micro hydraulic telescopic arm 4 rotates upward, it will gradually separate from the bracket 17.

[0045] Since the contact point between the micro hydraulic telescopic arm 4 and the slide 12 will transition from the arc surface 122 to the flat surface 123 during the process of the micro hydraulic telescopic arm 4 rotating downward to be reset, the torsion spring 13 will reset in the later stage of the reset of the micro hydraulic telescopic arm 4, so that the slide 12 will start to descend synchronously with the micro hydraulic telescopic arm 4, resulting in the situation that the support rod 16 starts to be retracted before the micro hydraulic telescopic arm 4 is completely reset, affecting the stability of the equipment in the working state. To avoid this situation, the specific operations are as follows:

[0046] When the micro hydraulic telescopic arm 4 rotates upward, the micro hydraulic telescopic arm 4 gradually disengages from the bracket 17, and the tension spring 18 in a stretched state gradually resets and drives the bracket 17 to slide to the left. During the upward movement of the slide 12, it will contact the arc surface 2 171 of the bracket 17. The slide 12 squeezes the arc surface 2 171 to make the bracket 17 slide to the right, so that the tension spring 18 is stretched. When the slide 12 moves upward to disengage from the arc surface 2 171, the tension spring 18 resets and drives the bracket 17 to slide to the left and reset. In this way, when the slide 12 slides upward and over the bracket 17, the bracket 17 can limit the slide 12. The micro hydraulic telescopic arm 4 must be completely horizontally retracted into the box body 1 before the bracket 17 slides to the right to release the limit on the slide 12, and the slide 12 starts to slide downward again, thereby achieving the effect of delaying the retraction of the support rod 16.

[0047] Combined with Fig. 9 The portable geological radar measuring equipment also includes sliders 19 symmetrically distributed front to back, and there are eight sliders 19 in total. The sliders 19 are slidably connected to the inner bottom of the box body 1 along the front and rear directions. The sliders 19 are arranged in an obtuse triangle shape, and the inclination angle of the right inclined surface of the slider 19 is greater than the inclination angle of the left inclined surface of the slider 19. The slider 19 is arranged corresponding to the position of the moving frame 3. When the moving frame 3 moves to the left, it contacts the right inclined surface of the slider 19, and when the moving frame 3 moves to the right, it contacts the left inclined surface of the slider 19. A fourth spring 20 is fixedly connected between the slider 19 and the box body 1.

[0048] When the movable frame 3 slides to the left or right, the movable frame 3 will be hindered by the slider 19 and the sliding speed will be slowed down, so as to prevent the movable frame 3 from sliding too fast and stopping suddenly due to the blocking effect of the box 1, and the vibration generated will be transmitted to the geological radar detector 5 to damage the geological radar detector 5;

[0049] When the moving frame 3 slides to the left, it is driven by the rapid rebound of the second spring 8 in the compressed state, and the driving speed is relatively faster. When the moving frame 3 slides to the right, it is driven by the downward moving baffle 9 squeezing the roller 11, and the driving speed is relatively slower. Therefore, the force required to decelerate when the moving frame 3 slides to the left is greater, so the inclination angle of the right side inclined surface of the slider 19 is set to be greater than the inclination angle of the left side inclined surface of the slider 19.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
