Description

Technical Field

[0001] The utility model relates to the field of highway engineering detection equipment, in particular to a highway engineering roadbed compaction detection device. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. The compaction degree of highway subgrade must be tested during construction. The compaction degree of subgrade is one of the key indicators for the quality inspection of subgrade and pavement construction. It characterizes the density after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. The compaction degree of the subgrade is used to determine whether the project meets the standards. Commonly used inspection methods include sand injection and water injection. During the inspection, inspection equipment is used to drill holes in the subgrade for sampling, or to drill holes and inject sand or water. The traditional drilling method is to drill holes in the subgrade with a manual handheld drill. However, when drilling with a handheld drill, it is not conducive to stable control of the drill to drill vertically downward, and the depth of the drill cannot be accurately controlled.

[0003] In order to solve the above problems, we propose a highway engineering roadbed compaction detection equipment to improve the shortcomings of the existing technology. Utility Model Content

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0020] like Figure 1-3 As shown, a highway engineering roadbed compaction detection equipment comprises a trolley 1, a hanging frame 2 is welded and fixed on the trolley 1, a drilling device is arranged under the hanging frame 2, the drilling device comprises a cylinder 3, a hanging plate 4, a motor 5, a drill rod 7, a sleeve 8 and an L-shaped positioning plate 9, two cylinders 3 that move synchronously are fixed on the bottom wall of the top of the hanging frame 2, a hanging plate 4 is fixed on the protruding end of the cylinder 3, a motor 5 is fixed above the hanging plate 4, the output shaft of the motor 5 extends to the bottom of the hanging plate 4 and is connected to the drill rod 7, a sleeve 8 is fixed on the inner wall of one side of the hanging frame 2, an L-shaped positioning plate 9 that can be pulled up and down is inserted into the sleeve 8, and the L-shaped positioning plate 9 is squeezed and fixed on the sleeve 8 by a locking bolt 10, forming an overall highway engineering roadbed compaction detection equipment structure, adopting mechanization to replace manual drilling sampling or drilling sand filling and water filling detection, which saves time and labor and is convenient and fast.

[0021] In this embodiment, a bearing is provided at the connection between the output shaft of the motor 5 and the hanging plate 4 to ensure the smooth rotation of the output shaft of the motor 5. A chuck 6 is also fixed to the end of the output shaft of the motor 5, and the drill rod 7 is fixed on the chuck 6 for easy disassembly and replacement.

[0022] In this embodiment, a controller 11 is also fixed on the top of the hanging frame 2. The controller 11 is electrically connected to the cylinder 3 and the motor 5 to facilitate the start and stop of the equipment.

[0023] In this embodiment, side grooves 12 are provided on both sides of the vehicle plate of the trolley 1, and a removable pedal 13 is inserted in the side groove 12, so that a person can stand on the pedal 13 to press the trolley 1 firmly on the ground to avoid the trolley 1 from tilting due to the hard roadbed when drilling.

[0024] In this embodiment, handrails 14 are fixed on the outer walls of both sides of the hanging frame 2 to facilitate people to stand firmly.

[0025] In this embodiment, a through hole is further provided on the vehicle plate of the trolley 1 , and the through hole is located directly below the drill rod 7 , so as to ensure that the drill rod 7 passes through the vehicle plate of the trolley 1 to drill a hole on the roadbed.

[0026] In this embodiment, the bottom of the L-shaped positioning plate 9 is located below one end of the hanging plate 4 , ensuring that the L-shaped positioning plate 9 can limit the hanging plate 4 .

[0027] The principle and advantages of the utility model: when using this roadbed compaction detection device for highway engineering, drilling sampling detection is carried out on the highway roadbed, the device is first pushed to the detection site, the drilling sampling point is marked on the highway, and then the trolley 1 is pushed so that the drill rod 7 is located directly above the marked point, and then the trolley 1 is pushed to the drill rod 7. Figure 2As described, lock the universal wheel at the bottom of the trolley 1, connect the controller 11 to the power supply, turn on the cylinder 3, let it extend, let the drill rod 7 fall to the ground, and then set the drilling depth. For example, if the drilling depth is set to 10 cm, first screw the two locking bolts 10 outward to allow the L-shaped positioning plate 9 to move up and down, then use a ruler to measure the distance between the bottom of the hanging plate 4 and the bottom cross plate of the L-shaped positioning plate 9, adjust the distance between the two to 10 cm, and then screw the locking bolts 10 inward to firmly squeeze the L-shaped positioning plate 9 on the sleeve 8 to fix it, and then pull out a part of the pedal 13 in the side groove 12. Two operators stand on the pedals 13 on both sides respectively, hold the handrails 14 with their hands, and turn on the motor 5 and the cylinder 3 through the controller 11. The motor 5 rotates with the drill rod 7, and the cylinder 3 presses down the drill rod 7, thereby drilling holes on the highway roadbed for sampling. Figure 3 As shown, when the depth of the borehole reaches 10 cm, the hanging plate 4 contacts the horizontal plate of the L-shaped positioning plate 9, and the L-shaped positioning plate 9 blocks the hanging plate 4 from descending, and the drill rod 7 no longer continues to drill. After the drilling is completed, the cylinder 3 is retracted, the motor 5 is turned off, the drill rod 7 is lifted, and the sample in the hole is taken out for detection, or sand or water is poured into the hole for detection. This highway engineering roadbed compaction detection equipment adopts mechanization to replace manual drilling sampling or drilling sand and water testing, which saves time and labor, is convenient and fast, and is easy to transfer, thereby improving practicality.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
