Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a thickness detection device for shotcrete. Background Art
[0002] Concrete spraying machine is a device that uses compressed air to continuously transport concrete along the pipeline and spray it onto the construction surface. It is widely used in lining construction of underground projects, tunnels, etc. After actual construction, in order to ensure the quality of concrete after spraying, the depth of the sprayed concrete needs to be tested.
[0003] In the prior art, generally, a hole is drilled at the detection point manually with a metal rod or the like, and then a tape measure or a ruler is used to measure the adhesion distance of the concrete on the metal rod, so as to roughly judge the thickness of the sprayed concrete.
[0004] Since the above method is divided into two steps of drilling and measuring, the operation process is relatively cumbersome, which will bring inconvenience to the inspection personnel, is not conducive to improving the inspection efficiency, and correspondingly increases the inspection cost, which needs to be improved. Utility Model Content

[0016] In a preferred example, the utility model can be further configured as follows: a rope loop is provided on the support seat.
[0017] In a preferred example, the present invention can be further configured as follows: a plug hole is provided at one end of the support seat, and a plug rod for plugging into the plug hole is rotatably connected to the other end.
[0018] In summary, the utility model has the following beneficial effects:
[0019] 1.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0026] like Figure 1 , Figure 2 As shown, a device for detecting the thickness of shotcrete comprises a support base 1, a gantry 2 and a detection rod 3. The support base 1 is used to be attached to the concrete surface to be tested, the gantry 2 is arranged on the support base 1, and the detection rod 3 passes through the gantry 2 and the support base 1, and is slidably connected to the support base 1.
[0027] like Figure 1 , Figure 2 As shown, a handle 31 is provided at the tail end of the detection rod 3, and a limiting ring 32 for contacting the top wall of the gantry 2 is provided in the middle. A spring 33 is sleeved on the detection rod 3, and the spring 33 is located between the gantry 2 and the handle 31.
[0028] like Figure 1 , Figure 2 As shown, a scale 34 is provided on the handle 31, and the scale 34 is vertical to the support seat 1. The scale 34 passes through the gantry 2, and the gantry 2 is provided with an observation hole 21 aligned with the scale on the scale 34. A convex lens 22 is embedded in the observation hole 21 for magnifying the reading and facilitating observation and reading.
[0029] When testing the thickness of concrete, the support base 1 is laid flat on the concrete surface, and the detection rod 3 is in contact with the concrete surface. Then the handle 31 is pressed to drive the detection rod 3 to move, so that the detection rod 3 penetrates into the concrete. At the same time, the handle 31 drives the scale 34 to move synchronously. The penetration of the detection rod 3 is proportional to the sliding of the scale 34. The penetration depth of the detection rod 3 can be known by observing the vertical position of the hole 21, so as to conveniently and accurately determine the thickness of the concrete.
[0030] When the detection is completed, release the handle 31, and the spring 33 controls the detection rod 3 to move in the opposite direction until the limit ring 32 on the detection rod 3 hits the gantry 2, so that the detection rod 3 is fixed, and the end face of the detection rod 3 is in contact with the ground of the support seat 1, which is convenient for the next detection.
[0031] Therefore, by providing a push-type detection rod 3 and a scale 34 on the detection rod 3, the depth of the detection rod 3 inserted into the concrete can be intuitively displayed, and the sprayed thickness of the concrete can be accurately known immediately, making the concrete thickness detection process easier and more convenient, improving the detection efficiency, and reducing the detection cost.
[0032] like Figure 1 , Figure 2 As shown, a cleaning ring 11 is embedded in the outer wall of the support seat 1 for the detection rod 3 to pass through, so when the detection rod 3 retreats, the cleaning ring 11 can automatically clean the detection rod 3 to ensure the cleanliness of the detection rod 3 and at the same time ensure the smoothness of the sliding process of the detection rod 3.
[0033] like Figure 1 , Figure 2As shown, a writing board 12 is rotatably connected to the support base 1, and a writing pen 13 is embedded on the support base 1 and located beside the writing board 12. Therefore, when the detected values need to be recorded, the writing board 12 and the writing pen 13 are used to quickly record the detected values, which is convenient for recording the measured values multiple times.
[0034] like Figure 1 , Figure 2 As shown, a rope loop 14 is provided on the support base 1 to realize the lifting of the support base 1, so as to facilitate carrying or hanging storage of the entire device.
[0035] like Figure 1 , Figure 2 As shown, a plug hole 15 is provided at one end of the support base 1, and a plug rod 16 for plugging into the plug hole 15 is rotatably connected to the other end.
[0036] Therefore, when it is necessary to detect the thickness of concrete, the two support seats 1 can be combined, and then the positions of the two support seats 1 can be controlled so that a pair of support seats 1 are horizontal or vertical, which can not only realize synchronous detection of different positions on the same horizontal plane, but also realize synchronous detection of the ground and side walls, making the detection process more convenient and quick, improving the detection efficiency, and reducing the detection cost.
[0037] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
