Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, and in particular relates to a concrete surface crack observation and marking device. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. Concrete has the characteristics of abundant raw materials, low price, and simple production process, which makes its usage increasingly large. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades, which makes its application very wide.

[0003] Concrete surface crack monitoring devices play a crucial role in assessing the quality of concrete structures. While existing devices on the market can meet basic crack detection needs to some extent, they still exhibit several significant shortcomings in practical applications. For example, operators must manually scan the concrete surface point by point using a handheld probe. This method is not only cumbersome and inefficient, but also prone to operator fatigue during prolonged operation. Furthermore, existing devices lack effective marking capabilities after crack detection, failing to accurately locate and label the cracks. This undoubtedly creates significant inconvenience for subsequent crack repair and maintenance, increasing maintenance difficulty and workload, and ultimately impacting the overall safety and service life of the concrete structure.

[0004] Therefore, there is an urgent need to improve the existing concrete surface crack observation and marking device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a concrete surface crack observation and marking device, which solves the problem that existing concrete surface crack observation devices require operators to hold a probe and scan the concrete surface point by point. This detection method is not only cumbersome and inefficient, but also easily leads to operator fatigue during long-term operation. In addition, existing concrete surface crack observation devices lack effective marking functions after detecting cracks, and cannot accurately locate and mark the discovered cracks. This undoubtedly brings great inconvenience to subsequent crack repair and maintenance work, increases the difficulty and workload of maintenance, and affects the overall safety and service life of concrete structures.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a concrete surface crack observation and marking device, comprising an observation base, universal wheels movably mounted on both sides of the lower end of the observation base, an observation groove opened in the middle of the lower end of the observation base, a flaw detection probe installed inside the observation groove, a mounting frame mounted on the upper end of the observation base, a hand-held rod rotatably mounted in the middle of the mounting frame, a marking structure provided between the hand-held rod and the observation base, and an alarm electrically connected to the flaw detection probe provided at one end of the hand-held rod.

[0007] A further feature of this invention is that the marking structure includes a marking liquid tank, which is located at the upper end inside the observation seat, and an addition hole is provided on one side of the marking liquid tank.

[0008] A further feature of this invention is that a hydraulic groove is provided inside the observation base, the hydraulic groove is located below the marking liquid groove, a liquid discharge pipe is provided at the upper end of the hydraulic groove and connected to the lower end of the marking liquid groove, and a one-way valve is provided inside the liquid discharge pipe.

[0009] A further feature of this invention is that spray grooves are provided on both sides of the upper end of the hydraulic tank, one end of the spray groove extends into the interior of the observation tank, and a movable groove is provided inside the spray groove.

[0010] A further feature of this invention is that an installation base is fixedly installed inside the movable groove, a retaining bead is movably inserted at one end of the installation base, one end of the retaining bead is engaged with the connection between the movable groove and the spray groove, and a support spring is fixedly installed on one side of the retaining bead.

[0011] A further feature of this invention is that a movable groove is provided in the middle of the upper end of the observation seat, a hydraulic plate is movably installed inside the hydraulic groove, an adjusting rod is installed at the upper end of the hydraulic plate, the upper end of the adjusting rod is movably inserted inside the movable groove and is fitted with a connecting seat, and a return spring connected to the connecting seat is sleeved on the surface of the adjusting rod.

[0012] A further feature of this invention is that the connecting seat has a connecting groove inside, a support wheel frame is provided at the upper end of the moving groove, a traction rope is movably inserted in the middle of the support wheel frame, and the lower end of the traction rope is movably inserted inside the connecting groove and is equipped with a connecting block.

Detailed Implementation

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figures 1 to 3 As shown, this embodiment provides a concrete surface crack observation and marking device, including an observation base 100. Universal wheels 103 are movably installed on both sides of the lower end of the observation base 100. An observation groove 104 is opened in the middle of the lower end of the observation base 100. A flaw detection probe 110 is installed inside the observation groove 104. A mounting frame 101 is installed on the upper end of the observation base 100. A handheld rod 200 is rotatably installed in the middle of the mounting frame 101. A marking structure is provided between the handheld rod 200 and the observation base 100. An alarm 210 electrically connected to the flaw detection probe 110 is provided at one end of the handheld rod 200.

[0027] In this embodiment, the handheld lever 200 rotates flexibly inside the mounting bracket 101. This design greatly facilitates the user's precise adjustment of the observation base 100 from different angles, ensuring that the observation base 100 can effectively and meticulously observe the concrete at higher positions on the wall. Simultaneously, this flexible rotation mechanism also allows the observation base 100 to easily perform omnidirectional inspections of the ground. With cleverly designed casters 103, the user can easily move the observation base 100, greatly improving the flexibility and convenience of the inspection. When the flaw detector 110 detects cracks in the concrete during inspection, the alarm 210 immediately activates and issues a warning signal. This function effectively alerts on-site personnel, ensuring they can take timely measures to guarantee construction safety and quality.

[0028] like Figures 4 to 6As shown in the figure, this embodiment provides a concrete surface crack observation and marking device. The marking structure includes a marking liquid tank 120, which is located at the upper end of the observation base 100. An adding hole is provided on one side of the marking liquid tank 120. A hydraulic tank 130 is provided inside the observation base 100, located below the marking liquid tank 120. A lowering pipe 121, connected to the lower end of the marking liquid tank 120, is provided at the upper end of the hydraulic tank 130. A one-way valve 1 is provided inside the lowering pipe 121. 22. Spraying channels 132 are provided on both sides of the upper end of the hydraulic tank 130. One end of the spraying channel 132 extends into the interior of the observation tank 104. A movable channel 134 is provided inside the spraying channel 132. A mounting base 135 is fixedly installed inside the movable channel 134. A retaining bead 136 is movably inserted into one end of the mounting base 135. One end of the retaining bead 136 engages with the connection between the movable channel 134 and the spraying channel 132. A support spring 137 is fixedly installed on one side of the retaining bead 136. The upper end of the observation base 100... A movable groove is provided in the middle of the hydraulic groove 130. A hydraulic plate 131 is movably installed inside the hydraulic groove 130. An adjusting rod 133 is installed on the upper end of the hydraulic plate 131. The upper end of the adjusting rod 133 is movably inserted into the movable groove and is equipped with a connecting seat 310. A return spring 313 connected to the connecting seat 310 is sleeved on the surface of the adjusting rod 133. A connecting groove 311 is provided inside the connecting seat 310. A support wheel frame 102 is provided at the upper end of the movable groove. A traction rope is movably inserted in the middle of the support wheel frame 102. 300, the lower end of the traction rope 300 is movably inserted into the inside of the connecting groove 311 and is equipped with a connecting block 312. The inside of the hand handle 200 is movably installed with a movable plate 221. The lower end of the movable plate 221 is equipped with a connecting spring 222. The movable plate 221 is connected to one end of the traction rope 300. Both sides of the hand handle 200 are provided with sliding grooves. The sliding grooves are movably inserted with sliders connected to the movable plate 221. The surface of the hand handle 200 is movably fitted with an adjusting ring 220 connected to the slider.

[0029] In this embodiment, after the alarm 210 is activated and begins operation, the user needs to manually pull the adjusting ring 220. The adjusting ring 220, through a connected slider mechanism, drives the movable plate 221 to move accordingly. During this process, the movable plate 221 stretches the spring connected to it, thereby storing a certain amount of elastic potential energy. As the movable plate 221 moves, the traction rope 300 connected to it also moves, and the movement of the traction rope 300 further drives the displacement of the connecting block 312. The connecting block 312, as an intermediate transmission component, continues to transmit power to the connecting seat 310, causing the connecting seat 310 to also begin to move. The movement of the connecting seat 310 stretches the reset spring 313, ensuring that the entire mechanism can reset in subsequent operations.

[0030] Meanwhile, the movement of the connecting seat 310 also causes the adjusting rod 133 to move accordingly. The movement of the adjusting rod 133 directly acts on the hydraulic plate 131, causing it to move precisely inside the hydraulic tank 130. The movement of the hydraulic plate 131 inside the hydraulic tank 130 will exert a squeezing effect on the marking liquid in the tank, forcing the marking liquid into the interior of the spray tank 132. The marking liquid in the spray tank 132 applies pressure to the retaining bead 136. Under the pressure, the retaining bead 136 moves towards the mounting seat 135. This process will compress the support spring 137, providing the necessary power for the marking liquid to be sprayed out.

[0031] Finally, under the compression of the support spring 137, the marking liquid is sprayed out from the spray tank 132, making it convenient for the user to accurately mark the gap position. After the marking operation is completed, the user releases the adjusting ring 220, and the hydraulic plate 131 returns to the initial position under the action of the return spring 313. The marking liquid inside the hydraulic tank 130 is replenished into the marking liquid tank 120 through the connecting pipe, ensuring that the entire marking structure can be reused, thus improving the practicality and work efficiency of the equipment.
