Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a highway bearing capacity test detection device. Background Art

[0002] The bearing capacity of the roadbed and pavement refers to the deformation resistance of the roadbed and pavement structure under the action of vehicle loads, and deflection is usually used as an on-site detection indicator. Deflection refers to the total vertical deformation value or vertical rebound deformation value of the roadbed or pavement surface under the action of a specified load. When the pavement is rolled over by vehicles for a long time, it will cause the pavement to deflect and cause cracks or gaps in the pavement. Traditional detection devices often use the Beckman beam method. Since the Beckman beam has a long overall length, the corresponding detection pavement must have the same length, and the pavement needs to have a certain degree of flatness. When encountering uneven and raised pavement, it cannot be detected in time.

[0003] Prior art, for example, a utility model of a highway bearing capacity test detection device, authorization announcement number CN219752926U. When a person pushes the utility device or uses a vehicle to tow it, if the ground is uneven, it will squeeze the sense spring plate, and the sense spring plate will collide with the ground, generating a signal to the processor, and the processor controls the alarm to turn on, reminding the person that there is a problem with the road surface.

[0004] At present, there is still a lack of a device in which the detection head moves along the width of the road to expand the detection range. When encountering protrusions and depressions with edges close to vertical, the detection head is raised to pass over the protrusions and depressions to facilitate detection.

[0005] Therefore, in view of the above problems, a highway bearing capacity test and detection equipment is proposed to solve the above problems. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the utility model develops a highway bearing capacity test and detection device, which can conveniently realize highway bearing capacity test and detection, and conveniently avoid protrusions and depressions with edges close to verticality.

[0007] The technical solution of the utility model to solve the technical problem is as follows: the utility model provides a highway bearing capacity test detection equipment, including: a detection vehicle, the upper side of which is connected to a mounting frame, the mounting frame is connected to a control display screen; symmetrical electric push rods, respectively connected to the detection vehicle, the push rods of the symmetrical electric push rods respectively pass through the detection vehicle, and the push rods of the symmetrical electric push rods are respectively connected to U-plates; a screw rod, the two ends of which are respectively connected to the U-plate by bearings; a group of detection heads, respectively connected to sliders, the screw rod passes through a group of sliders, the two reverse threads of the screw rod are respectively threadedly connected to the sliders corresponding to the two ends, the sliders at the two ends are respectively rotated to connect one end of the side rod, and the other sliders are respectively rotated to connect the center of the connecting rod, and one end of the adjacent connecting rods is respectively coaxially cross-rotated, and the other ends of the two side rods are respectively rotated to connect one end of the corresponding connecting rod. By adopting the electric push rod, it is convenient to realize the lifting and lowering of the detection head as a whole, and it is convenient to realize the detection of the device and avoid the protrusions and depressions close to the vertical edge. By adopting the method of connecting rod rotation connection, when the sliders on both sides move, the relevant sliders are driven to move, so as to realize the movement of part of the test head and expand the detection range.

[0008] As an optimization, the detection head includes a guide tube and a pressure sensor. The pressure sensor and the guide tube are respectively connected to the corresponding slider. The guide tube is provided with the pressure sensor, a spring and a ball head rod. The pressure sensor is connected to the ball head rod through the spring. By making the ball head rod contact the road surface, the spring is compressed, and the pressure sensor measures the pressure value. By the change of the pressure value of the pressure sensor, it is determined whether it is convex or concave, so as to realize the highway bearing capacity test detection.

[0009] As an optimization, the screw is connected to a small gear, the U-plate bearing is connected to a large gear, the small gear meshes with the large gear, the large gear is connected to a notch rod, a wheel of the inspection vehicle is connected to a circular plate, the eccentric part of the circular plate is connected to a power round block, and the power round block is arranged in the groove of the notch rod. By adopting gear meshing and utilizing the rotation of the wheel, the screw is driven to rotate back and forth.

[0010] As an optimization, the U plate is connected to a guide rod, the guide rod passes through a group of the sliders, and the guide rod is connected to a middle slider. The number of sliders in a group is an odd number, and the guide rod is connected to the middle slider. When the screw rod rotates, the remaining sliders except the middle slider move.

By using the camera, it is convenient to find protrusions and depressions with edges close to verticality, and it is convenient to operate the electric push rod to retract later.

[0012] As an optimization, the mounting frame is connected to an alarm, and the alarm is electrically connected to the control display screen. By using the alarm, an alarm prompt is issued when the pressure of the pressure sensor changes.

[0013] As an optimization, the detection vehicle is connected with a handle, which facilitates the movement of the device.

[0014] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] (1) This device uses an electric push rod to facilitate the lifting and lowering of the detection head as a whole, making it easier for the device to detect and avoid protrusions and depressions with nearly vertical edges.
