Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soil drilling and sampling devices, specifically a subgrade bed quality testing device for railway supervision. Background Technology
[0002] The quality inspection of railway subgrade is an important part of ensuring the stability and safety of railway lines. The quality inspection of subgrade usually includes the thickness, strength, stiffness, water stability, frost stability and the bonding between the layers of filler.
[0003] Referring to the authorized patent application CN217974291U, a railway subgrade bed quality measuring device belongs to the field of subgrade bed quality measurement technology. It includes a base plate, with a support frame, a water tank, and a housing fixedly connected to the top of the base plate. A first motor frame is fixedly connected to the top of the support frame. The advantages of this railway subgrade bed quality measuring device are that, through the operation of a second drive motor, it can drive a drill bit to rotate, drill holes in the ground soil, and remove the soil for easy observation and testing. Through the operation of a high-pressure water pump, it can pump clean water from the water tank to the ground, spraying water onto the ground for easy monitoring and recording of soil conditions. A spring can be used to limit the storage box and protect its interior. A scale line can be set to control the drilling depth into the soil, facilitating soil testing.
[0004] As shown in the prior art, in order to facilitate land testing, the existing railway subgrade quality measuring device sometimes takes soil samples by drilling, so that the soil samples can be used to test the subgrade. However, the existing drilling and sampling device is inefficient. It usually involves drilling through the soil and then manually sampling, or drilling into the soil one by one using sampling tubes that are fixed to the machine body by threads, and then removing the sampling tubes with the samples taken and replacing them with new sampling tubes. The operation steps are cumbersome.
[0005] Therefore, it is necessary to provide a railway subgrade quality testing device for railway supervision to solve the above-mentioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a railway subgrade bed quality testing device for railway supervision.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a railway subgrade bed quality testing device for railway supervision, comprising a machine body, a lifting assembly installed on one side of the machine body, a machine head fixed at the moving end of the lifting assembly, a turntable rotatably connected to the side of the machine head away from the machine body, and a horizontal plate fixed to the side of the turntable away from the machine head;
[0008] The horizontal plate is fixed with inserts on both the upper and lower sides. Sampling cylinders are detachably inserted into the outer wall of the inserts. A clamping assembly for clamping one of the sampling cylinders is installed on the side of the turntable near the horizontal plate.
[0009] The machine head is equipped with a rotating assembly that drives the turntable to rotate.
[0010] Preferably, the rotating assembly includes a motor fixed to the machine head and on the side away from the machine body, and a rotating shaft fixed to the side of the turntable near the motor, the rotating shaft passing through the machine head and fixed to the output end of the motor.
[0011] Preferably, a base plate is fixed to the side of the machine head near the turntable, and the turntable is rotatably connected to the outer wall of the base plate.
[0012] Preferably, the clamping assembly includes electric push rods symmetrically rotatably connected to the turntable on the side away from the motor, and a clamping plate rotatably connected to the telescopic ends of the two electric push rods. The clamping plate is rotatably connected to the horizontal plate, and the end of the clamping plate near the turntable abuts against the outer wall of the sampling cylinder.
[0013] Preferably, both ends of the clamp are provided with grooves, and the outer wall of the sampling tube is movably connected to the inner wall of the groove.
[0014] Preferably, an anti-slip pad is fixed to the inner wall of the groove.
[0015] This utility model provides a railway subgrade quality testing device for railway supervision. Compared with the prior art, it has the following advantages:
[0016] 1. The horizontal plate has fixed insertion posts on both the top and bottom sides. Sampling tubes are detachably inserted into the outer wall of the insertion posts. The rotating component allows the sampling tube that has completed sampling and the sampling tube to be sampled to be quickly switched between the two positions. This design effectively improves sampling efficiency.
[0017] 2. This application, through the design of the clamping component, can firmly clamp the sampling tube, ensuring the stability of the sampling tube during the sampling process. The grooves opened at both ends of the clamping plate increase the contact area between the clamping plate and the sampling tube, and the anti-slip pads fixed on the inner wall of the groove further improve the clamping stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides two technical solutions:
[0025] Figures 1 to 3 The first embodiment is shown: a railway subgrade bed quality testing device for railway supervision, including a body 1, a lifting component 9 installed on one side of the body 1, a machine head 2 fixed at the moving end of the lifting component 9, a turntable 3 rotatably connected to the side of the machine head 2 away from the body 1, and a horizontal plate 4 fixed to the side of the turntable 3 away from the machine head 2.
[0026] The upper and lower sides of the horizontal plate 4 are fixed with insertion posts 5. The outer wall of the insertion post 5 is detachably inserted with a sampling tube 6. The turntable 3 is installed on the side near the horizontal plate 4 with a clamping component for clamping one of the sampling tubes 6.
[0027] The machine head 2 is equipped with a rotating assembly that drives the turntable 3 to rotate.
[0028] The rotating assembly includes a motor 7 fixed to the machine head 2 on the side opposite to the machine body 1, and a rotating shaft fixed to the side of the turntable 3 near the motor 7. The rotating shaft passes through the machine head 2 and is fixed to the output end of the motor 7.
[0029] A base plate 8 is fixed on the side of the machine head 2 near the turntable 3, and the turntable 3 is rotatably connected to the outer wall of the base plate 8.
[0030] The horizontal plate 4 has fixed insertion posts 5 on both the upper and lower sides. The sampling tube 6 is detachably inserted into the outer wall of the insertion post 5. The rotating component allows the sampling tube 6 that has completed sampling to quickly switch positions with the sampling tube 6 to be sampled. This design effectively improves sampling efficiency.
[0031] Figures 2 to 4The second embodiment is shown. The main difference from the first embodiment is that the clamping assembly includes electric push rods 10 that are symmetrically rotatably connected to the turntable 3 on the side away from the motor 7. The telescopic ends of the two electric push rods 10 are rotatably connected to a clamping plate 11. The clamping plate 11 is rotatably connected to the horizontal plate 4. The end of the clamping plate 11 near the turntable 3 is pressed against the outer wall of the sampling cylinder 6.
[0032] The clamping plate 11 has grooves 12 at both ends. The outer wall of the sampling tube 6 is movably connected to the inner wall of the groove 12. The inner wall of the groove 12 is fixed with an anti-slip pad.
[0033] The application uses a clamping component design to firmly clamp the sampling tube 6, ensuring the stability of the sampling tube 6 during the sampling process. The grooves 12 at both ends of the clamping plate 11 increase the contact area between the clamping plate 11 and the sampling tube 6. The anti-slip pads fixed to the inner wall of the grooves 12 further enhance the clamping stability.
[0034] Working principle:
[0035] The lifting assembly 9 mainly consists of a housing, a screw rotatably connected to the housing, and a head 2 threadedly connected to the outer wall of the screw. The head 2 is slidably connected to the inner wall of the housing, and the transmission screw can drive the head 2 to lift and lower within the inner wall of the housing. This is existing technology and will not be described in detail here.
[0036] Start the machine body 1 to reach the sampling point of the railway subgrade bed for railway supervision. Use the lifting assembly 9 to lower the machine head 2 to the lowest point. Insert a sampling tube 6 into the outer wall of the upper insertion post 5. Then start the two electric push rods 10 to drive the clamping plate 11 to flip, so that the groove 12 above the clamping plate 11 is tightly against the outer wall of the sampling tube 6. Then the lifting assembly 9 drives the machine head 2 to rise, and the sampling tube 6 rises with it. The motor 7 drives the rotating shaft to rotate, and the turntable 3 rotates on the outer wall of the base plate 8, flipping the sampling tube 6 downward. Then the machine head 2 lowers, so that the sampling tube 6 drills into the soil for sampling.
[0037] After the machine head 2 descends and partially penetrates the sampling tube 6 into the soil, a second sampling tube 6 awaiting sampling can be inserted into the upper insertion post 5. Wait for the first sampling tube 6 to finish sampling and rise until it is completely out of the soil. Then, use the electric push rod 10 to rotate the clamping plate 11, causing the clamping plate 11 to release the lower first sampling tube 6 and clamp the second sampling tube 6 on the outer wall of the upper insertion post 5. At this point, remove the lower first sampling tube 6. Move the machine body 1 to the second sampling point and rotate the turntable 3 so that the second sampling tube 6 faces downwards, allowing the second sampling tube 6 to be used for sampling. Repeat this process, and then the soil samples in the sampling tubes 6 can be taken out for quality testing of the railway subgrade.
