Description

Technical Field

[0001] The utility model relates to the technical field of road surface detection, in particular to a bridge head road surface subsidence detection device. Background Art

[0002] Pavement diseases refer to the various damages, deformations and other defects that will occur on cement or asphalt pavement after a period of use. Common early diseases include: cracks, potholes, rutting, looseness, subsidence, bridge head culvert top jumping, surface damage, etc. The pavement at the bridge head is prone to subsidence due to roadbed problems. Usually, the staff uses laser radar equipment to detect the subsidence of the bridge head pavement.

[0003] In summary, the current bridgehead road subsidence detection equipment has gradually been found to have the following defects during use:

[0004] (1) The push rods on most traditional subsidence detection equipment are of fixed length and cannot be retracted or folded. They take up a lot of space during transportation, which not only causes inconvenience in transportation, but also increases transportation costs and the risk of damage.

[0005] (2) Most subsidence detection equipment is not equipped with a marking device. After detecting the subsidence, only the data is recorded without marking. When subsequent rectification is carried out, it is easy to find the original position, resulting in the need for secondary detection, which is a great waste of manpower and material resources. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the utility model is to provide a bridge head road subsidence detection device to solve the technical problem that the pushing rods on most of the current traditional subsidence detection devices are of fixed length and cannot be retracted or folded, and occupy a very large space during transportation, which not only causes transportation inconvenience, but also leads to an increase in transportation costs and increases the risk of damage.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A bridge head road subsidence detection device comprises a detection vehicle body, a plurality of wheels are respectively provided on both sides of the detection vehicle body, a laser detection component is arranged inside the detection vehicle body, a handle is fixedly provided on the top of the detection vehicle body, a first hinge is fixedly provided on the top of the detection vehicle body, the first hinge is hinged to a square tube, a square block is sleeved on the square tube, connecting shafts are respectively provided on both sides of the square block, special-shaped connecting rods are hinged on the connecting shafts, the special-shaped connecting rods are hinged to a second hinge, a telescopic rod is arranged inside the square tube, a push handle is fixedly provided at one end of the telescopic rod, a third hinge is fixedly provided on the push handle, the third hinge is hinged to a movable platform, the movable platform is fixedly provided with a fourth hinge, the fourth hinge is hinged to a connecting rod, and the connecting rod is hinged to a fifth hinge.

[0010] As an improved technical solution, wherein: a sliding groove is provided inside the square tube, the telescopic rod is retracted in the sliding groove, a threaded through hole is provided on the square block, a flower-shaped bolt is provided inside the threaded through hole, and the second hinge is fixedly arranged on the top of the inspection vehicle body.

[0011] As an improved technical solution, wherein: a T-shaped slot is provided on one side of the telescopic rod, a T-shaped bolt is provided inside the T-shaped slot, the T-shaped bolt passes through the corresponding through hole on the first hinge, and a locking nut is threadedly connected to the T-shaped bolt.

[0012] As an improved technical solution, wherein: a plurality of groups of threaded holes are provided on one side of the telescopic rod, and a tightening bolt is provided on the fifth hinged member, and the tightening bolt is threadedly connected to the threaded hole.

[0013] As an improved technical solution, wherein: a marking liquid storage chamber is provided inside the detection vehicle body, a connecting channel is provided on one side of the marking liquid storage chamber, an electromagnetic valve is provided on the connecting channel, a dispersion pipe is provided at one end of the connecting channel, and a liquid outlet is provided on the outer surface of the dispersion pipe.

[0014] As an improved technical solution, a liquid filling port is fixedly provided on the top of the detection vehicle body.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The utility model shrinks and folds the entire push rod through the square tube, the telescopic rod and the special-shaped connecting rod. At the same time, the movable stand can also be folded up through the connecting rod. After the push rod is shrunk and folded, the space occupied during transportation is very small, which not only does not cause transportation inconvenience, but also reduces transportation costs and reduces the risk of damage.

[0017] 2. The utility model opens the electromagnetic valve, and the marking liquid flows out from the marking liquid storage chamber, flows into the dispersion pipe through the connecting channel, and then flows to the ground through the liquid outlet to be marked. In this way, after the subsidence is detected, the data is recorded and the ground is also marked. When rectification is carried out later, it is easy to find the marked position without secondary inspection, which saves a lot of manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS
