DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] like Figures 1 to 3As shown, a quality inspection device for rail transit construction according to an embodiment of the present invention comprises a motor 1; a rotating shaft 15 is fixedly connected to the output end of the motor 1; a left sampling tube 12 and a right sampling tube 11 are hingedly connected to the end of the rotating shaft 15; in a specific embodiment of the present invention, the upper ends of the left sampling tube 12 and the right sampling tube 11 are connected to the end of the rotating shaft 15 through a first rotating shaft 13, and the left sampling tube 12 and the right sampling tube 11 are both semi-cylindrical structures, and the two are combined into a complete cylindrical structure, and there is a cavity inside; the first rotating shaft 13 and the left sampling tube 1 2. The right sampling tube 11 is connected by a torsion spring; the left sampling tube 12 and the right sampling tube 11 are symmetrically arranged and have the same internal structure; the side walls of the left sampling tube 12 and the right sampling tube 11 are in contact; the bottom ends of the left sampling tube 12 and the right sampling tube 11 are slidably connected with a limit ring 14; during operation, during the rail transit construction stage, after filling the foundation, the staff can turn the ends of the left sampling tube 12 and the right sampling tube 11 downward, so that the left sampling tube 12 and the right sampling tube 11 are sampled downward along the specified position, specifically, the staff turns on the motor 1, and the limit ring 14 is turned on. The ring 14 is fixed to the bottom of the left sampling tube 12 and the right sampling tube 11 to fix the two. At this time, the rotating shaft 15 drives the left sampling tube 12 and the right sampling tube 11 to rotate simultaneously under the action of the current. This is because the staff applies downward pressure to force the right sampling tube 11 and the left sampling tube 12 to enter the formation. The formation can be separated through the cylindrical cavity formed between the right sampling tube 11 and the left sampling tube 12, and the soil sample is retained in the cylindrical cavity to achieve sampling. After the sampling is completed, the staff increases the upward force on the motor 1 to drive the right sampling tube 11 and the left sampling tube 1 2 moves upward to make it off the ground. At this time, the staff rotates the right sampling tube 11 and the left sampling tube 12 along the first rotating shaft 13 to achieve left-right separation, releases the soil sample and obtains the sampling layer. The right sampling tube 11 and the left sampling tube 12 can rotate left and right on the first rotating shaft 13, and the sampling layer can be completely leaked out by rotating left and right after sampling, so that the staff can directly observe and inspect the filling and stratification of the internal materials of the foundation, so as to make timely adjustments to the foundation filling materials and provide support for the operation of the subsequent rail transit system.

[0033] like Figure 3As shown, the right sampling tube 11 and the left sampling tube 12 are both arranged in sections; each section of the left sampling tube 12 is connected by a No. 2 rotating shaft 2; a No. 1 slide groove 21 is provided in the middle of the left sampling tube 12; a fixing rod 22 is slidably connected inside the No. 1 slide groove 21; the fixing rod 22 and the No. 1 slide groove 21 are connected by a spring; the fixing rod 22 is arranged in sections, and the sections are in the same position as the sections of the left sampling tube 12; a fixing hole 23 is provided at the top of the fixing rod 22; a fixing block 24 is slidably connected to the top of the left sampling tube 12; during operation, when the staff uses the right sampling tube 11 and the left sampling tube 12 for sampling, the sections of the fixing rod 22 and the sections of the left sampling tube 12 maintain an up-and-down misalignment state, so that the multiple sections of the left sampling tube 12 are fixed on the fixing rod 22 The left sampling tube 12 and the fixed rod 22 are placed flat by the staff, so that the left sampling tube 12 and the fixed rod 22 are in the same plane. The left sampling tube 12 can be bent one by one to reveal the sampling layer. The segmented setting of the left sampling tube 12 and the fixed rod 22 can be used to bend the tube after sampling to assist the staff in removing the sampling layer more conveniently and completely, reduce the partial adhesion of the sampling layer when the sampling layer is opened at one time, and reduce the large bending stress formed by directly opening the left sampling tube 12 and the right sampling tube 11, reduce the occurrence of fractures in the sampling layer, and affect the observation effect, so as to affect the overall progress of rail transit construction.

[0034] like Figures 4 to 5 As shown, a No. 2 slide groove 3 is provided on the contact surface of multiple groups of the fixed rods 22; each pair of the No. 2 slide grooves 3 is connected by a No. 1 elastic rope 33; a No. 1 magnet 31 and a No. 2 magnet 32 ​​are fixedly connected at the segmented parts inside the fixed rod 22; the No. 1 magnet 31 and the No. 2 magnet 32 ​​are magnetically attracted to each other; during operation, after extracting the sampling layer, the staff can reset the left sampling tube 12, and at this time, the elastic action of the No. 1 elastic rope 33 can assist the staff to connect multiple sections of the left sampling tube 12, and at the same time, the magnetic attraction effect of the No. 1 magnet 31 and the No. 2 magnet 32 ​​can provide fixation for the fixed rod 22, and the elastic effect of the No. 1 elastic rope 33 itself can assist the vertical reset of the left sampling tube 12 and the fixed rod 22, thereby increasing the stability of the equipment during operation, and at the same time, the staff can manually operate to extract the sampling layer more accurately and reduce damage to the sampling layer.

[0035] like Figures 4 to 5As shown, the inner side walls of the left sampling tube 12 and the right sampling tube 11 are fixedly connected with a connecting plate 4; the connecting plate 4 is arranged in sections; a plurality of groups of No. 3 magnets 41 are fixedly connected to the middle of the No. 1 elastic rope 33; a plurality of groups of No. 4 magnets 42 are arranged on the side wall of the connecting plate 4 close to the left sampling tube 12; the No. 4 magnets 42 and the connecting plate 4 are connected by a connecting rope; the No. 3 magnets 41 and the No. 4 magnets 42 are attracted to each other by magnetic force; when working, the No. 1 elastic rope 33 is pulled and deformed, which will drive When the No. 3 magnet 41 moves, the No. 4 magnet 42 installed on the side wall of the connecting plate 4 is attracted by the magnetic force and moves along with the No. 3 magnet 41. After the No. 3 magnet 41 moves away, the No. 4 magnet 42 hits the side wall of the connecting plate 4 under the action of its own gravity. The magnetic attraction effect of the No. 3 magnet 41 and the No. 4 magnet 42 can make the sampling layer vibrate when it is detached, thereby reducing the damage of the sampling layer caused by the adhesion of the sampling layer to the side wall of the connecting plate 4 when it is detached, affecting the observation integrity.

[0036] like Figure 5 As shown, there are multiple groups of limit blocks 5 fixedly connected to both sides of the No. 3 magnet 41 inside the No. 2 slide 3; a pair of blocking plates 51 are installed on the side walls of the multiple groups of limit blocks 5; the blocking plates 51 themselves are made of elastic material; when working, during the movement of the No. 3 magnet 41, it will continuously pass between the pair of limit blocks 5. At this time, the pair of blocking plates 51 installed on the side walls of the limit blocks 5 can block the No. 3 magnet 41 twice. As the tension of the No. 1 elastic rope 33 increases, the No. 3 magnet 41 will drive the No. 3 magnet 41 to deform, so that the No. 3 magnet 41 passes smoothly, and a setback effect is generated after the No. 3 magnet 41 is subsequently detached. The blocking effect of the limit blocks 5 and the blocking plates 51 on the No. 3 magnet 41 will produce a setback effect during the bending process of the left sampling tube 12 by the staff, and the knocking of the auxiliary No. 4 magnet 42 will drive the sampling layer to detach smoothly, reduce the damage to the sampling layer, and maintain the integrity of the sampling layer.

[0037] like Figures 5 to 7As shown, the side wall of the connecting plate 4 away from the No. 4 magnet 42 is provided with a plurality of No. 3 slide grooves 6; the inside of the connecting plate 4 is slidably connected with a rubber coating 61; the rubber coating 61 covers the side wall of the No. 3 slide groove 6; one end of the rubber coating 61 is wound around the No. 1 rotating shaft 13; the other end of the rubber coating 61 is fixedly connected to the bottom end of the connecting plate 4; during operation, as the right sampling tube 11 and the left sampling tube 12 continue to penetrate deeper, the No. 3 slide groove 6 provided on the side wall of the connecting plate 4 can increase the friction between the No. 3 slide groove 6 and the soil, thereby assisting The left sampling tube 12 and the right sampling tube 11 drive the sampling layer to move. At the same time, when the left sampling tube 12 is bent to detach the sampling layer, the rubber coating 61 will be pulled, driving the rubber coating 61 inside the No. 3 chute 6 to form a bending plane. The opening of the No. 3 chute 6 can facilitate the staff to extract the sampling layer. At the same time, the plane formed by the pulling of the rubber coating 61 can assist the staff to detach the sampling layer, reducing the sampling layer adhering to the side wall of the No. 3 chute 6, causing the integrity to be destroyed and affecting the observation effect.

[0038] like Figure 7 As shown, the rubber coating 61 is located inside the No. 3 slide 6 and is fixedly connected to the side wall thereof with the No. 2 elastic rope 7; the plurality of groups of left sampling tubes 12 are located inside the No. 3 slide 6 and are provided with No. 4 slides 71 on both the upper and lower sides; the rubber coating 61 slides inside the No. 4 slide 71; a cam 72 is provided between the No. 4 slide 71 and the rubber coating 61; the other end of the No. 2 elastic rope 7 is fixedly connected to the side wall of the cam 72; during operation, when the staff bends the left sampling tubes 12 of different sections, the rubber coating 61 is pulled During the process, the rubber coating 61 inside the No. 3 slide 6 is driven to move, and the No. 2 elastic rope 7 is pulled, so that the No. 2 elastic rope 7 drives the cam 72 to roll, and the cam 72 and the side wall of the rubber coating 61 are constantly in contact. At this time, the protrusion of the cam 72 itself will drive the cam 72 to jump. The movement of the rubber coating 61 can drive the cam 72 to rotate, and the sampling layer attached to the rubber coating 61 can be loosened and cleaned, which is convenient for the staff to completely detach the sampling layer and improve the observation accuracy of the sampling layer.

[0039] like Figure 7As shown, a No. 5 magnet 8 is fixedly connected to one end of the inner side wall of the No. 4 slide groove 71 away from the No. 3 slide groove 6; a No. 6 magnet 81 is fixedly connected to the inside of the cam 72; the No. 5 magnet 8 and the No. 6 magnet 81 are magnetically attracted to each other; during operation, when the rubber coating 61 pulls the No. 2 elastic rope 7, the cam 72 moves under the pulling action, and at this time, the magnetic attraction between the No. 5 magnet 8 and the No. 6 magnet 81 can assist the subsequent left sampling tube 12 to be reset, and drive the cam 72 to return to the initial position, so as to facilitate the subsequent rolling contact with the rubber coating 61 again, and utilize the magnetic attraction effect of the No. 5 magnet 8 and the No. 6 magnet 81 to assist the cam 72 to be reset during resetting, so as to facilitate the cam 72 to roll on the side wall of the rubber coating 61 during subsequent sampling, thereby providing a vibration effect and reducing the sampling layer from adhering to the rubber coating 61, so as to affect the sampling structure.

[0040] like Figure 5 As shown, multiple groups of side walls of the connecting plate 4 are fixedly connected with rubber balls 9 at the contact positions with the No. 4 magnets 42; the No. 4 magnets 42 are in contact with the rubber balls 9; during operation, when the No. 4 magnets 42 are moved by the magnetic attraction of the No. 3 magnets 41, after subsequently breaking away from the magnetic effect, the No. 4 magnets 42 move under the influence of gravity and collide with the rubber balls 9, and the No. 4 magnets 42 are driven to bounce multiple times by the elasticity of the rubber balls 9 themselves, and the elastic effect of the rubber balls 9 themselves can assist the No. 4 magnets 42 to continue bouncing during the collision to produce multiple collision effects, thereby providing vibration support for the separation of the sampling layer and reducing the situation where the sampling layer is attached to the side walls of the connecting plate 4.

[0041] Embodiment 2

[0042] like Figure 8 As shown, compared with Example 1, another implementation of the present invention is: the side walls of the No. 2 slide groove 3 are all provided with a No. 5 slide groove 101 at the positions of multiple groups of limit blocks 5; the limit blocks 5 are rotated inside the No. 5 slide groove 101 through torsion springs; during operation, during the movement of the No. 3 magnet 41, the blocking plate 51 drives the limit blocks 5 to rotate inside the No. 5 slide groove 101 through contact with the No. 3 magnet 41, thereby providing resistance while reducing the jamming situation. The opening of the No. 5 slide groove 101 and the rotation of the limit blocks 5 can reduce the jamming of the No. 3 magnet 41 and the limit blocks 5, thereby improving the stability of the equipment during use.

[0043] When working, during the rail transit construction phase, after filling the foundation, the staff can turn the ends of the left sampling tube 12 and the right sampling tube 11 downward, so that the left sampling tube 12 and the right sampling tube 11 can be sampled downward along the specified position. Specifically, the staff turns on the motor 1, fixes the limit ring 14 at the bottom of the left sampling tube 12 and the right sampling tube 11, and fixes the two. At this time, the rotating shaft 15 drives the left sampling tube 12 and the right sampling tube 11 to rotate at the same time under the action of the electric current. This is because the staff applies downward pressure to force the right sampling tube 11 and the left sampling tube 12 to enter the stratum. The cylindrical cavity formed between the right sampling tube 11 and the left sampling tube 12 can separate the stratum, and the soil sample can be retained in the cylindrical cavity to achieve sampling. After the sampling is completed, the staff increases the upward force of the motor 1 to drive the right sampling tube 11 and the left sampling tube 12 to move upward and make them leave the ground. At this time, the staff rotates the right sampling tube 11 and the left sampling tube 12 along the first rotation axis 13 to achieve left-right separation, release the soil sample and obtain the sampling layer. When the staff uses the right sampling tube 11 and the left sampling tube 12 for sampling, the segmented parts of the fixing rod 22 and the segmented parts of the left sampling tube 12 maintain an up-and-down misalignment state, so that the multiple sections of the left sampling tube 12 are kept in a vertical fixed state under the fixing effect of the fixing rod 22, which is convenient for sampling. After the sampling is completed, the fixing rod 22 is provided with a downward squeezing force, and the sliding fixing block 24 is fixed at the fixing hole 23. The staff drives 12 and 11 to be laid flat, so that the sections of the left sampling tube 12 and the fixing rod 22 are on the same plane, and the left sampling tube 12 can be bent one by one to leak out the sampling layer. After the sampling layer is extracted, the staff can reset the left sampling tube 12. At this time, the elastic action of the No. 1 elastic rope 33 can assist the staff to connect multiple sections of the left sampling tube 12. At the same time, the magnetic attraction effect of the No. 1 magnet 31 and the No. 2 magnet 32 ​​can provide fixation for the fixing rod 22. During the pulling and deformation process of the No. 1 elastic rope 33, the No. 3 magnet 41 will be driven to move. At this time, the No. 4 magnet 42 installed on the side wall of the connecting plate 4 is attracted by the magnetic attraction effect and moves with the No. 3 magnet 41. After the No. 3 magnet 41 moves away, the No. 4 magnet The iron 42 is aggregated and hits the side wall of the connecting plate 4 under the action of its own gravity. During the movement of the No. 3 magnet 41, it will continuously pass between a pair of limit blocks 5. At this time, a pair of blocking plates 51 installed on the side wall of the limit block 5 can block the No. 3 magnet 41 twice. As the tension of the No. 1 elastic rope 33 increases, the No. 3 magnet 41 will drive the No. 3 magnet 41 to deform, so that the No. 3 magnet 41 can pass smoothly, and a setback effect will be produced after the No. 3 magnet 41 is separated. During the continuous deepening of the right sampling tube 11 and the left sampling tube 12, the No. 3 slide groove 6 opened on the side wall of the connecting plate 4 can increase the friction between the soil and assist the left sampling tube 12 and the right sampling tube 11 to drive the sampling layer to move. At the same time, when the left sampling tube 12 is bent to separate the sampling layer,The rubber coating 61 will be pulled, driving the rubber coating 61 inside the No. 3 chute 6 to form a bending plane. When the staff bends the left sampling tube 12 of different sections, the rubber coating 61 drives the rubber coating 61 inside the No. 3 chute 6 to move during the pulling process, pulling the No. 2 elastic rope 7, so that the No. 2 elastic rope 7 drives the cam 72 to roll, so that the cam 72 and the side wall of the rubber coating 61 are constantly in contact. At this time, the protrusion of the cam 72 itself drives the cam 72 to jump, and the rubber coating 61 pulls the No. 2 elastic rope 7. When the cam 72 is pulled, the cam 72 moves under the pulling action. At this time, the magnetic attraction between the fifth magnet 8 and the sixth magnet 81 can assist the subsequent resetting of the left sampling tube 12, driving the cam 72 to return to the initial position, so as to facilitate the subsequent rolling contact with the rubber coating 61. When the fourth magnet 42 is affected by the magnetic attraction of the third magnet 41 and moves, after the subsequent separation from the magnetic effect, the fourth magnet 42 moves under the influence of gravity and collides with the rubber ball 9, and the elasticity of the rubber ball 9 drives the fourth magnet 42 to bounce multiple times.
