Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a roadbed quality detection and coring device. Background Art

[0002] In the field of road engineering, the quality of the roadbed, as the foundation of the road structure, is directly related to the service life of the road and driving safety. In order to ensure that the quality of the roadbed meets the design standards, regular or irregular quality inspections are required. When inspecting the quality of the roadbed, it is usually necessary to obtain samples from the inside of the roadbed through drilling and coring for testing.

[0003] For the convenience of mobility, most of the current drilling and coring equipment are equipped with casters at the bottom. When performing fixed-point coring operations, it is necessary to use multiple support legs with adjustable heights to lift the equipment off the ground. In the actual operation process, in order to ensure the stability of the equipment installation, the operator is required to repeatedly calibrate and adjust the height of each support leg. The operation is cumbersome, time-consuming and labor-intensive, which reduces work efficiency. Therefore, the applicant proposes a roadbed quality inspection and coring device to solve the above problems. Utility Model Content

[0006] The flip mechanism includes a bidirectional screw rod rotatably installed in the base along the length direction of the base and two movable arms symmetrically distributed and respectively assembled on both sides of the bidirectional screw rod, the ends of both sides of the two movable arms are hinged with flip plates, and the base is provided with four movable grooves for hinged and embedded flip plates, the four flip plates are distributed symmetrically around the center and a moving wheel is fixedly installed on the bottom of each flip plate, the ends of the middle parts of the two movable arms are hinged with threaded sleeves, and the two threaded sleeves are respectively threadedly assembled on the outer walls of both sides of the bidirectional screw rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The roadbed quality inspection and coring device can drive two sets of threaded sleeves to move relative to each other by rotating the bidirectional screw rod.

DETAILED DESCRIPTION

[0020] The following embodiments will be combined with the accompanying drawings to describe the utility model in detail. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the utility model are only used to illustrate the utility model, and are not used to limit the scope of the utility model. Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0021] See also Figure 1-5 The utility model proposes a coring device for roadbed quality inspection, comprising a base 1 and a turning mechanism 3 installed in the base 1, a bracket mechanism 5 fixedly installed on the top of the base 1 and a coring mechanism 6 installed on the bracket mechanism 5. The turning mechanism 3 comprises a bidirectional screw rod 4 rotatably installed in the base 1 along the length direction of the base 1 and two movable arms 2 symmetrically distributed and respectively installed on both sides of the bidirectional screw rod 4. The ends of both sides of the two movable arms 2 are hinged with turning plates 301. Four movable grooves 102 for hinged and embedded turning plates 301 are provided on the base 1. The four turning plates 301 are centrally symmetrically distributed and a moving wheel 302 is fixedly installed at the bottom of each turning plate 301. The ends of the middle parts of the two movable arms 2 are hinged with threaded sleeves 402, and the two threaded sleeves 402 are respectively threadedly installed on the outer walls of both sides of the bidirectional screw rod 4.

[0022] Based on the above-mentioned structural setting, the roadbed quality detection coring device is composed of a base 1, a movable arm 2, a flipping mechanism 3, a bidirectional screw rod 4, a bracket mechanism 5 and a coring mechanism 6, wherein the device can be conveniently moved to a suitable position for use by moving the base 1, the movable arm 2 can be adjusted by the bidirectional screw rod 4, the base 1 can be quickly supported and fixed on the ground by the flipping mechanism 3, the coring mechanism 6 can be movably supported by the bracket mechanism 5, and the coring mechanism 6 can be used to realize the drilling and coring operation. Specifically, in the working project, when the device is moved to a suitable position by the moving wheel 302, the threaded connection between the threaded sleeve 402 and the bidirectional screw rod 4 can be made, so that the bidirectional screw rod 4 can drive the two threaded sleeves 402 to move relative to each other when rotating, and can synchronously drive the movable arm 2 to move relative to each other, and when the movable arms 2 are driven to approach each other, the flip plate 301 can be pulled to The upward flipping can synchronously drive the moving wheel 302 to flip upward, so that the moving wheel 302 can flip and extend into the movable groove 102. The movable groove 102 can protect the moving wheel 302 during the drilling and coring process. When the moving wheel 302 shrinks and is in the movable groove 102, the support seat 101 can be in contact with the ground, and the base 1 can be supported and fixed. During the coring process, the core taking mechanism 6 can keep the device from shaking easily. The fixing operation is simple and fast. When the device is moved to a suitable position, the device can be quickly fixed. By operating the two-way screw rod 4 for reverse rotation, the movable arms 2 can be pushed away from each other, and the flip plate 301 can be driven to flip downward, so that the moving wheel 302 can be in contact with the ground again, and the base 1 can be quickly supported to separate the support seat 101 from the ground. The device can be pushed and moved conveniently and timely, and the work efficiency is effectively improved.

[0023] Furthermore, four support seats 101 are fixedly installed at the bottom of the base 1 in a rectangular array, and anti-skid patterns are provided at the bottom of the four support seats 101. The support seats 101 can support the base 1 by contacting the ground, and the anti-skid patterns can increase the friction between the support seats 101 and the ground to avoid sliding.

[0024] Furthermore, one end of the bidirectional screw rod 4 away from the coring mechanism 6 extends to the outside of the base 1 and is fixedly mounted with an operating disk 401, which is coaxially distributed with the bidirectional screw rod 4. The operating disk 401 can be used to conveniently operate the bidirectional screw rod 4 for rotation, and the flip plate 301 can be quickly flipped.

[0025] Further, the support mechanism 5 includes two slide posts 501 vertically mounted on the top of the base 1 and a fixed plate 502 distributed and covered on the top of the two slide posts 501 along the horizontal plane, and two fixed rods 503 are fixedly connected between one side of the fixed plate 502 and the top of the base 1. Among them, the fixed plate 502 can be strengthened and fixed by the fixed rod 503, so that the slide posts 501 are not easy to shake, and a stable support effect can be provided for the coring mechanism 6. The driving rod 7 can be an electric push rod or a hydraulic push rod, which can conveniently drive the coring mechanism 6 to move up and down, and facilitate the coring operation on the ground.

[0026] Furthermore, the coring mechanism 6 includes a driving rod 7 penetrating the fixed plate 502 in the vertical direction, and a sliding seat 602 fixedly connected to the bottom end of the driving rod 7 and slidably mounted on the outside of the two sliding columns 501, and a motor 601 is fixedly mounted on the sliding seat 602, and the output end of the motor 601 penetrates the sliding seat 602 and is fixedly connected to the drill tube 603. Among them, the sliding seat 602 can slide up and down along the sliding column 501, and the drill tube 603 can be driven to rotate by the motor 601. The driving rod 7 is used to push the sliding seat 602 to move downward, so that the drill tube 603 can be extended to the ground for drilling. By driving the drill tube 603 to move upward, the staff can conveniently take out the geological samples in the drill tube 603, and conveniently perform the detection operation on the samples.
