[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0021] like Figures 1 to 8 As shown, the tunnel lining anti-seepage performance testing equipment of the present invention includes a base 1 and a radar processing device 6. The base 1 is the supporting plane of the entire equipment. A handrail is fixedly connected to the base 1 to facilitate personnel operation to achieve self-service displacement and movement.
[0022] A steering wheel 2 and a direction adjusting device 4 for driving the steering wheel 2 to steer are mounted at one end of the base 1. Two steering wheels are provided. The steering wheel 2 is rotatably connected to a mounting frame. The direction adjusting device 4 comprises a steering motor. The rotating shaft of the steering motor is connected to the mounting frame of the steering wheel 2, thereby realizing automatic steering, thereby ensuring that the equipment can move at the axis of the tunnel lining when displaced.
[0023] The other end of the base 1 is provided with a moving wheel 3 and a protective shell 5 . The moving wheels 3 are provided with two and are fixedly connected by a cross bar 33 . Therefore, driving any one of the moving wheels 3 to rotate can realize the synchronous rotation of the two moving wheels 3 .
[0024] The direction adjustment device 4 is provided with an infrared detector and a displacement sensor, which will drive the steering wheel 2 to adjust the direction when the device moves along the axis to ensure that the device always moves on the axis of the tunnel during displacement, thereby ensuring the detection effect of the device.
[0025] The protective housing 5 is a hollow rectangular housing, and is located on the upper surface of the base 1. A progressive mechanism is installed in the protective housing 5, and the progressive mechanism includes a rotating component and a forward component.
[0026] The forward assembly includes a movable frame plate 18 that is slidably connected to the protective housing 5. The movable frame plate 18 is a rectangular frame structure with two upper and lower long sides extending to the left and right. The movable frame plate 18 is fixed with a slide plate 21 at both ends. The inner wall of the protective housing 5 is provided with a horizontal notch 25. The slide plate 21 is slidably connected to the notch 25.
[0027] The rotating assembly drives the movable frame plate 18 to move back and forth. The rotating assembly includes a motor 10, a rotating shaft 11 fixedly connected to the output shaft of the motor 10, and an outer tube 12 axially slidably connected to the rotating shaft 11. The motor 10 is fixedly connected to the positioning plate 9, and the positioning plate 9 is fixedly connected in the protective housing 5. The rotating shaft 11 extends forward and backward, and the outer tube 12 is sleeved on the rotating shaft 11, and the axial sliding connection is realized by a sliding key.
[0028] like Figure 6 As shown, a rotating drum 13 is fixedly connected to the outer tube 12. The rotating drum 13 is a hollow circular tube and is coaxially arranged with the rotating shaft 11. A spiral circulation groove 15 is provided on the inner circle of the rotating drum 13. The rotating assembly also includes a fixed round rod 17 fixedly connected to the protective shell 5. The fixed round rod 17 is coaxial with the rotating drum 13. A slider 16 inserted into the circulation groove 15 is fixedly connected to the fixed round rod 17. Therefore, when the motor 10 rotates, it can drive the rotating drum 13 to rotate. The axial movement of the rotating drum 13 during rotation is achieved through the cooperation of the circulation groove 15 and the slider 16.
[0029] The outer ring of the rotating drum 13 is fixedly connected with multiple circles of tooth block groups 14, each tooth block group 14 includes multiple tooth blocks arranged circumferentially, the rotating drum 13 passes through the movable frame plate 18, and the movable frame plate 18 is provided with rack plates 19 on both the upper and lower sides and arranged front and back. When the multiple circles of the tooth block groups 14 move axially, they are alternately meshed with the two rack plates 19, thereby driving the movable frame plate 18 to move back and forth left and right. Specifically, when the tooth block group 14 on the outer side of the rotating drum 13 moves axially, it meshes with the rack plate 19 above. The movable frame plate 18 is driven to move to one side by rotation, and the tooth block group 14 on the outside of the drum 13 separates from the upper rack plate 19 when continuing to move axially, and then engages with the lower rack plate 19, thereby driving the movable frame plate 18 to move to the other side. The movable frame plate 18 can be reciprocated left and right by multiple groups of tooth block groups 14. When the slider 16 moves to the end of the circulation slot 15, the drum 13 can move in the opposite direction, so that the movable frame plate 18 can still be reciprocated left and right.
[0030] The protective housing 5 is axially connected with a connecting pipe 7 extending forward and backward. The connecting pipe 7 extends forward and backward. The horn antenna 8 of the radar processing device 6 is fixedly connected to one side of the front end of the connecting pipe 7. Figure 4As shown, a rack plate 23 is fixedly connected to the upper side of the movable frame plate 18, and a gear 24 meshing with the rack plate 23 is fixedly connected to the connecting pipe 7. When the rack plate 23 moves back and forth with the movable frame plate 18, the gear 24 is driven to rotate back and forth, and the connecting pipe 7 drives the horn antenna 8 to perform a uniform reciprocating rotation adjustment of 0° to 180°, thereby facilitating and effectively releasing and receiving electromagnetic waves for the tunnel lining, and using the radar processing device 6 to receive and analyze data.
[0031] In order to realize automatic walking of the equipment during the detection process, it is best to stop after walking a certain distance, and then continue walking a certain distance, so as to achieve the best detection result.
[0032] like Figure 7 As shown, the forward component also includes a rotating rod 27 axially connected to the protective shell 5 on both sides and symmetrically rotatably connected, and a rotating block 26 is fixedly connected to the rotating rod 27. The rotating block 26 is cylindrical and the axis extends left and right. The two rotating blocks 26 are respectively connected to the two moving wheels 3 for transmission. In order to realize the transmission connection, in this embodiment, the side of the rotating block 26 is fixedly connected to a belt pulley 29, and the outer side of the moving wheel 3 is fixedly connected to a receiving rod 32. The receiving rod 32 is fixedly connected to a belt pulley 2 31. The belt pulley 2 31 and the belt pulley 1 29 are connected by a belt 30, so that the rotation of any one of the rotating blocks 26 can realize the rotation of the two moving wheels 3.
[0033] The movable frame plate 18 is fixedly connected to side plates 20 on both left and right sides, and a vertical bottom sliding rod 22 is fixedly connected to the side plate 20. The outer circle of the rotating block 26 is provided with a guide slot 28 for accommodating the bottom sliding rod 22 to be inserted. The guide slot 28 includes an inclined section and a horizontal section extending left and right. The inclined sections of the guide slots 28 of the two rotating blocks 26 are inclined in opposite directions and are circumferentially staggered.
[0034] The method of using the present invention: The moving wheel 3 rotates to move, and the steering wheel 2 is used to achieve steering, and the equipment is moved to the tunnel axis of the area to be detected, and then the motor 10 and the radar processing device 6 are started, and electromagnetic waves are emitted from the horn antenna 8 and reflected waves are received. The motor 10 drives the rotating shaft 11 to rotate, and the outer tube 12 is driven to rotate synchronously under the axial sliding of the rotating shaft 11 and the outer tube 12, and the rotating drum 13 rotates synchronously, and the sliding block 16 is guided in the circulation groove 15 to make the rotating drum 13 rotate and move axially at the same time. When the tooth block group 14 on the outside of the rotating drum 13 moves axially, it meshes with the rack plate 19 above, and drives the movable frame plate 18 to move to one side through rotation. When the tooth block group 14 on the outside of the rotating drum 13 continues to move axially, it separates from the rack plate 19 above, and then meshes with the rack plate 19 below, thereby driving the movable frame plate 18 to move to the other side. The movable frame plate 18 can be reciprocated left and right by multiple groups of tooth block groups 14. When the slider 16 moves to the end of the circulation slot 15, the rotating drum 13 can move in the opposite direction, so that the movable frame plate 18 can still be reciprocated left and right.
[0035] As the movable frame plate 18 moves back and forth left and right, the rack plate 23 at the top can be meshed with the gear 24, driving the connecting pipe 7 to drive the horn antenna 8 to perform a uniform reciprocating rotation adjustment of 0° to 180°, thereby facilitating the effective release and reception of electromagnetic waves for the tunnel lining, and using the radar processing device 6 to receive and analyze data.
[0036] As the movable frame plate 18 moves back and forth left and right, and finally utilizes the matching setting of the bottom sliding rod 22 and the guide slot 28, as the bottom sliding rod 22 slides along the inclined section of the guide slot 28, and the continuous sliding of the movable frame plate 18 will push the rotating block 26 to rotate at a certain angle, with the rotation of the rotating block 26, it can synchronously drive the pulley 1 29 to drive the belt 30 to transmit, and transmit the power to the pulley 2 31 to drive the two sets of moving wheels 3 to perform a single displacement, drive the horn antenna 8 to synchronously displace, and perform automatic and comprehensive detection of the tunnel lining in the area, greatly improving the detection and receiving efficiency of the equipment, and realizing automatic and orderly detection of the tunnel lining axis.
[0037] After the bottom slide bar 22 moves to the end of the inclined section of the guide slot 28, the movable frame plate 18 is set to move in the opposite direction at this time, so as to escape through the horizontal section, and then the other bottom slide bar 22 moves to the inclined section of the guide slot 28 on the other side, and continues to drive the other rotating block 26 to rotate, so that the equipment continues to move a certain distance.
[0038] The direction adjustment device 4 is provided with an infrared detector and a displacement sensor, which will drive the steering wheel 2 to adjust the direction when the device moves along the axis to ensure that the device always moves on the axis of the tunnel during displacement, thereby ensuring the detection effect of the device.
