Description

Technical Field

[0001] The utility model relates to the technical field of crack measurement, in particular to a measuring device for bridge cracks. Background Technique

[0002] After a bridge has been in use for some time, cracks may appear due to its own materials, external environment, and excessive loads. It is necessary to measure the width of the cracks and then take corresponding treatment measures according to the width.

[0003] When measuring cracks, the commonly used devices are rather troublesome to operate, the measuring parts are not easy to align with the cracks, and the structure is relatively complex and inconvenient to use. Therefore, those skilled in the art have provided a measuring device for bridge cracks to solve the problems raised. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a measuring device for bridge cracks.

[0005] The measuring device for bridge cracks provided by the utility model adopts the following technical scheme:

[0006] A measuring device for bridge cracks includes a vertical cylinder. An insertion block is movably inserted into the vertical cylinder. A threaded rod is fixedly installed at the center of the top of the insertion block. A spring is sleeved on the threaded rod and is located inside the vertical cylinder. A vertical pipe is arranged at the top of the vertical cylinder. The bottom of the vertical pipe contacts the top of the vertical cylinder. A threaded block is installed on the inner wall of the vertical pipe through threads. A top groove is opened at the top of the threaded block. A bolt is movably inserted into the top groove. The bottom of the bolt penetrates through the threaded block and is threadedly connected to the top of the threaded rod. The insertion block can be inserted into the crack to contact the edge. By rotating the vertical pipe to contact the top of the vertical cylinder, the corresponding distance can be measured.

[0007] Preferably, a plurality of positioning columns are uniformly and fixedly installed at the bottom of the threaded block. The positioning columns are inserted into the top end of the threaded rod. Corresponding circular holes adapted to the positioning columns are opened at the top of the threaded rod, which can position and install the threaded rod and the threaded block, and prevent the bolt from loosening and the threaded block from rotating with the vertical pipe.

[0008] Preferably, an anti-slip sleeve is fixedly sleeved on the outer side surface of the vertical pipe, which is convenient for rotating the vertical pipe.

[0009] Preferably, a top cover is installed on the top of the vertical pipe through threads, which is convenient for opening to assemble the threaded block.

[0010] Preferably, two limiting plates are symmetrically and fixedly installed on the inner walls of both sides of the vertical cylinder, which can limit the upward movement of the insertion block and protect the spring.

[0011] Preferably, the bottom of the insertion block is "V"-shaped, and a scale bar is arranged on the side surface of the insertion block, so that the corresponding width size can be intuitively seen.

[0012] In summary, the utility model includes the following beneficial technical effects:

[0013] 1. The insertion block can be lifted into the vertical cylinder for storage and protection. When measuring a crack, align the bottom of the insertion block with the bridge crack, make the bottom of the vertical cylinder fit the crack surface, make the two inclined surfaces on the insertion block fit the edge of the crack, and then rotate the vertical pipe through the anti-slip sleeve so that the bottom edge of the vertical pipe fits the top of the vertical cylinder. The scale of the scale bar corresponding to the bottom of the vertical cylinder is the width of the crack, and the operation is relatively simple.

[0014] 2. The positioning column is inserted on the surface of the threaded rod. The threaded rod and the threaded block are detachably installed, and the top cover and the vertical pipe are connected by threads, which is convenient for the overall assembly after production.

[0022] An embodiment of the utility model discloses a measuring device for bridge cracks.

[0023] A measuring device for bridge cracks includes a vertical cylinder 1. An insertion block 11 is movably inserted into the vertical cylinder 1. A threaded rod 12 is fixedly installed at the center of the top of the insertion block 11. A spring 13 is sleeved on the threaded rod 12. The spring 13 is located inside the vertical cylinder 1. A vertical pipe 2 is arranged at the top of the vertical cylinder 1. The bottom of the vertical pipe 2 contacts the top of the vertical cylinder 1. A threaded block 21 is installed on the inner wall of the vertical pipe 2 through threads. A top groove 24 is formed at the top of the threaded block 21. A bolt 23 is movably inserted into the top groove 24. The bottom of the bolt 23 penetrates through the threaded block 21 and is threadedly connected to the top of the threaded rod 12. The insertion block 11 can be inserted into the crack to contact the edge. By rotating the vertical pipe 2 to contact the top of the vertical cylinder 1, the corresponding distance can be measured.

[0024] A plurality of positioning columns 25 are uniformly and fixedly installed at the bottom of the threaded block 21. The positioning columns 25 are inserted into the top end of the threaded rod 12. Corresponding circular holes adapted to the positioning columns 25 are formed at the top of the threaded rod 12, which can position and install the threaded rod 12 and the threaded block 21, and prevent the bolt 23 from loosening and the threaded block 21 from rotating with the vertical pipe 2.

[0025] An anti-slip sleeve 22 is fixedly sleeved on the outer side of the vertical pipe 2, which is convenient for rotating the vertical pipe 2. A top cover 26 is installed on the top of the vertical pipe 2 through threads, which is convenient for opening to assemble the threaded block 21. Two limiting plates 14 are symmetrically and fixedly installed on the inner walls on both sides of the vertical cylinder 1, which can limit the upward movement of the insertion block 11 and protect the spring 13.

Align the bottom of the insertion block 11 with the bridge crack, make the bottom of the vertical cylinder 1 fit the surface of the crack, and make the two inclined surfaces on the insertion block 11 fit the edges of the crack. Then, rotate the vertical tube 2 through the anti-slip sleeve 22 so that the bottom edge of the vertical tube 2 fits the top of the vertical cylinder 1. The scale on the scale bar 15 corresponding to the bottom of the vertical cylinder 1 is the width of the crack. When continuous measurement is required, insert the insertion block 11 into the corresponding crack, rotate the vertical tube 2 and slowly adjust the position of the vertical cylinder 1 so that the insertion block 11 contacts both sides of the crack and the bottom of the vertical tube 2 contacts the top of the vertical cylinder 1. Then, the corresponding scale bar 15 is the crack width; The positioning post 25 is inserted into the surface of the threaded rod 12.
