Description

Technical Field

[0001] This utility model belongs to the field of bridge and tunnel inspection technology, and in particular relates to a bridge and tunnel crack detection device. Background Technology

[0002] The construction of bridges and tunnels helps overcome geographical barriers, allowing drivers to avoid having to travel longer distances to bypass obstacles such as mountains or rivers, greatly shortening travel time and improving traffic efficiency. During the construction and use of bridges and tunnels, external unstable factors may cause cracks to appear on the surface. To determine whether the existence of cracks poses a threat to driving safety, workers need to use bridge and tunnel crack detection devices to detect the cracks, obtain relevant data, and determine whether the bridge and tunnel can continue to be used, thereby increasing driving safety.

[0003] A search revealed a bridge tunnel crack detection device disclosed in patent document CN219723932U, but it still has the following drawbacks in practical use:

[0004] 1. The bridge tunnel crack detection device disclosed in the patent document with patent publication number CN219723932U has a height electric telescopic cylinder set in the middle of the front end of the detection box. The telescopic rod of the height electric telescopic cylinder has a telescopic drive mechanism set at the upper end. The entire section of the cleaning machine seat set inside the front end of the telescopic drive mechanism has a detection probe. Opening the height electric telescopic cylinder and the telescopic drive mechanism and adjusting the height and position of the detection probe on the horizontal plane facilitates the detection of bridge tunnel cracks. However, it is not convenient to adjust the tilt of the detection probe according to the tilt angle of the bridge tunnel crack, which reduces the scope of application and reduces practicality.

[0005] 2. The bridge tunnel crack detection device disclosed in the patent document with patent publication number CN219723932U has a gas delivery pump installed at the upper end of the detection box. The outer end of the gas delivery pump is located on a gas delivery hose installed on the cleaning machine base. When the gas delivery pump is powered on, gas is introduced into the gas delivery hose. The gas inside the gas delivery hose is sprayed towards the bridge tunnel crack to clean the debris inside the bridge tunnel crack. This effectively reduces the obstruction of debris to the operation of the detection probe. However, it is not convenient to collect the debris cleaned out of the bridge tunnel crack, which will cause dust to fly, have an adverse impact on the working environment, and even threaten the health of the workers due to excessive dust inhalation.

[0006] To address these issues, we provide a bridge and tunnel crack detection device. Utility Model Content

[0007] The purpose of this utility model is to provide a bridge and tunnel crack detection device. By setting an adjustment component, the height and tilt of the detection probe can be easily adjusted, making it convenient to detect cracks in bridges and tunnels at different heights and tilt angles, thus increasing the applicability. Furthermore, by setting a cleaning component, dust is effectively reduced during the cleaning process, which helps maintain a good working environment and reduces the threat to the health of workers. This solves the technical problem mentioned in the background art of the bridge and tunnel crack detection device disclosed in patent document CN219723932U.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a bridge and tunnel crack detection device, comprising a detection box, an adjustment assembly on the side wall of the detection box, the adjustment assembly including a hydraulic cylinder vertically connected to the side wall of the detection box, a mounting seat connected to the upper end of the piston rod at the telescopic end of the hydraulic cylinder, a motor connected to the side wall of the base connected to the outer side wall of the mounting seat, a rotating shaft connected in parallel to the output end of the motor, one end of the rotating shaft penetrating the side wall of the mounting seat, a connecting seat movably disposed inside the mounting seat connecting to the end of the rotating shaft, and a detection probe connected to the face of the connecting seat; a cleaning assembly connected to the upper surface of the detection box, the cleaning assembly including a bucket vertically connected to the upper surface of the detection box, a suction pump installed on the upper surface of the bucket lid, a connecting pipe connected to one end of the suction pump penetrating the bucket lid, and a connecting pipe connected to the other end of the suction pump connected to the upper surface of the connecting seat.

[0010] The present invention is further configured such that each of the four corners of the lower surface of the detection box is connected to a universal wheel, and a handle is connected to the upper edge of the side wall of the detection box, the handle being away from the hydraulic cylinder.

[0011] The present invention is further configured such that a detection port is provided on the side wall of the detection box, and a sealing plate is provided inside the detection port, and a screw with a rectangular array threaded connection on the outer side wall of the sealing plate is threaded to the side wall of the detection box.

[0012] The present invention is further configured such that a protruding shaft is fixedly connected to the side wall of the connecting seat away from the rotating shaft, and the protruding shaft is rotatably connected to the side wall of the mounting seat.

[0013] The present invention is further configured such that the mounting base has a U-shaped structure and the base has a Z-shaped structure.

[0014] The present invention is further configured such that a filter cylinder is fitted inside the water bucket, the upper surface of the filter cylinder is fixed by a sleeve, and the sleeve overlaps the upper surface of the water bucket.

[0015] The present invention is further configured such that the upper surface of the bucket has a ring array of fixed positioning rods, the positioning rods passing through the sleeve and the bucket lid from bottom to top, and the lower end of the screws of the ring array threaded on the upper surface of the bucket lid is threaded onto the positioning rods.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting an adjustment component, opens the hydraulic cylinder, and the piston rod at the telescopic end of the hydraulic cylinder extends or retracts, causing the mounting base to move up or down, adjusting the height of the detection probe on the connecting base. This facilitates the detection probe to detect cracks in bridges and tunnels at different heights. Furthermore, after the motor is powered on, the rotating shaft rotates, and the cam shaft rotates, causing the detection probe on the connecting base to move in an arc around the rotating shaft as a fixed point. The inclination of the detection probe can be adjusted according to the inclination angle of the bridge and tunnel cracks, increasing the scope of application and improving practicality.

[0018] 2. This utility model, by setting up a cleaning component, adjusts the inlet end of the connecting pipe during the adjustment of the detection probe, so that the inlet end of the connecting pipe is aligned with the crack in the bridge tunnel. When the suction pump is powered on, the debris inside the bridge tunnel crack enters the water tank through the connecting pipe, suction pump and connecting pipe. This effectively prevents the debris from obstructing the operation of the detection probe, allowing for better detection of the bridge tunnel crack. It also effectively reduces dust during the cleaning process, which is beneficial to maintaining the working environment and the health of the staff.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
