Description

Technical Field

[0001] The utility model relates to a device for measuring engineering geological fractures, belonging to the field of engineering geology. Background Technique

[0002] There are many types of geological fractures, including seismic geological fractures, tectonic creep geological fractures, etc., which are mainly caused by crustal movements or human factors. Engineering personnel delineate the dangerous areas of geological fractures and determine the damaged zones of geological fractures through the investigation and analysis of the geological environment of the region and the engineering site. According to the specific conditions of various buildings, the avoidance distances from the ground fissures are specified. For the already formed ground fissures, anti-cracking, anti-settlement and other measures need to be taken to prevent the damage of geological fractures. Specifically, methods such as backfilling, tamping, and grouting can be adopted for targeted treatment. During prevention and treatment, it is necessary to measure and analyze the geological fractures.

[0003] In the prior art, since a geological fracture measuring device is used when measuring geological fractures, and the measuring device is composed of a measuring instrument, a screen, a movable measuring rod, a backing plate and a grip rod, when using the measuring device, it is necessary to align the position of the measuring instrument with the gap, and at the same time start the movable measuring rod, so that the movable measuring rod pushes the abutting block to contact the inner wall of the gap, and at the same time observe the parameters on the screen, so that the use of the measuring device can be completed. However, when using the measuring device, since the sizes and depths of the gaps are different, when measuring a deeper gap, the staff's arm cannot reach into the gap to use the measuring device to measure the width of the gap. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device for measuring engineering geological fractures, so as to solve the problems put forward in the above background technique. The utility model can enable the measuring instrument to measure deeper gaps when the staff's arm cannot enter the gap.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A device for measuring engineering geological fractures, including a measuring instrument, a screen is fixedly arranged on the top surface of the measuring instrument, two symmetrically positioned movable measuring rods are fixedly connected to the side surface of the measuring instrument, and a backing plate is fixedly connected to the end of the movable measuring rod;

[0006] A receiving plate is fixedly installed on the surface of the measuring instrument, an arc plate is fixedly connected to the side surface of the receiving plate, a round block is fixedly installed on the surface of the receiving plate, a rotating block is rotatably connected to the inner side of the round block, a rotating rod is rotatably connected to the surface of the rotating block, a central block is fixedly arranged at the center of the surface of the rotating rod, a connecting block is fixedly connected to the surface of the central block, an electric telescopic rod is fixedly connected to the surface of the connecting block, a sleeve is fixedly arranged on the surface of the electric telescopic rod, a clamping block is fixedly installed on the surface of the round block, and a clamping bolt is movably connected to the center of the clamping block.

[0007] Further, arc plates that fit on the surface of the measuring instrument are respectively connected to both sides of the receiving plate. The arc plates are fixed on the surface of the measuring instrument. Two round blocks are symmetrically arranged on the surface of the receiving plate. Grooves matching the shape of the rotating blocks are formed on the side surfaces of the two round blocks at corresponding positions, and the rotating rod is connected to the two rotating blocks at the same time.

[0008] Further, the sleeve covers the surface of the electric telescopic rod. The connecting block is connected to the rotating rod and the electric telescopic rod at the same time. The position of the clamping block corresponds to the position of the rotating block, and the bolt passes through the clamping block and the round block and contacts the rotating block.

[0009] Further, a long plate is fixedly installed at the top of the side surface of the measuring instrument. A card slot is formed on the surface of the long plate. A side plate is fixedly installed on the side surface of the measuring instrument. A convex plate is fixedly arranged at the top of the side plate. A bolt is threadedly connected to the top of the convex plate. A fixing plate is fixedly connected to the bottom of the convex plate. A scraping plate is fixedly connected to the surface of the fixing plate. An arc groove is formed on the back surface of the moving measuring rod.

[0010] Further, one long plate and one side plate are symmetrically arranged on both sides of the measuring instrument respectively. Two grooves matching the surface shape of the moving measuring rod are formed at the center of the side plate. The bolt passes through the convex plate and contacts the fixing plate. The shape of the card slot is larger than the shape of the bolt at the top of the convex plate.

[0011] Further, the bottom of the fixing plate and the scraping plate contacts the surface of the moving measuring rod. The shape of the arc groove matches the shape of the scraping plate.

[0012] The beneficial effects of the present utility model: It is necessary to pull out the bolt and rotate the sleeve. The sleeve rotates at the positions of the rotating blocks on both sides along the rotating rod connected to the electric telescopic rod and the connecting block. The position of the sleeve is vertical. At the same time, place the measuring instrument in the gap, start the electric telescopic rod, so that the electric telescopic rod deepens the position of the measuring instrument into the gap, and then start the moving measuring rod to make the abutting plate contact the inner wall of the gap. At the same time, the parameters on the surface of the screen can be observed, so as to complete the measurement of a deeper gap when the staff's arm cannot enter the gap;

[0013] Secondly, it is necessary to install the long plate and the side plate on the side surface of the measuring instrument. At the same time, the fixing plate and the scraping plate at the bottom of the long plate contact the surface of the moving measuring rod. At this time, when the moving measuring rod contracts, due to the contact between the scraping plate and the surface of the moving measuring rod, the soil on the surface of the moving measuring rod is scraped off by the moving measuring rod. The arc groove on the back side of the abutting plate contacts the scraping plate, so that the retraction of the abutting plate will not be affected by the scraping plate. In this way, it can prevent the soil on the surface from being retracted together when the moving measuring rod contracts, which affects the normal use of the moving measuring rod.

A screen 2 is fixedly arranged on the top surface of the measuring instrument 1. Two symmetrically - positioned movable measuring rods 3 are fixedly connected to the side surface of the measuring instrument 1, and an abutting plate 301 is fixedly connected to the end of the movable measuring rod 3. Arc plates 401 that fit on the surface of the measuring instrument 1 are respectively connected to both sides of the receiving plate 4, and the arc plates 401 are fixed on the surface of the measuring instrument 1. Two round blocks 402 are symmetrically arranged on the surface of the receiving plate 4. Grooves matching the shape of the rotating block 403 are formed on the side surfaces of the two round blocks 402 at corresponding positions, and a rotating rod 404 connects the two rotating blocks 403 at the same time. A sleeve 502 covers the surface of the electric telescopic rod 501. A connecting block 5 connects the rotating rod 404 and the electric telescopic rod 501 at the same time. The position of the clamping block 6 corresponds to the position of the rotating block 403, and a bolt 601 passes through the clamping block 6 and the round block 402 and contacts the rotating block 403.

[0021] A receiving plate 4 is fixedly installed on the surface of the measuring instrument 1. An arc plate 401 is fixedly connected to the side surface of the receiving plate 4. A round block 402 is fixedly installed on the surface of the receiving plate 4. A rotating block 403 is rotatably connected to the inner side of the round block 402. A rotating rod 404 is rotatably connected to the surface of the rotating block 403. A central block 405 is fixedly arranged at the center of the surface of the rotating rod 404. A connecting block 5 is fixedly connected to the surface of the central block 405. An electric telescopic rod 501 is fixedly connected to the surface of the connecting block 5. A sleeve 502 is fixedly arranged on the surface of the electric telescopic rod 501. A clamping block 6 is fixedly installed on the surface of the round block 402. A bolt 601 is movably connected to the center of the clamping block 6.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , a long plate 7 is fixedly installed at the top of the side surface of the measuring instrument 1. A slot 701 is opened on the surface of the long plate 7. A side plate 8 is fixedly installed on the side surface of the measuring instrument 1. A convex plate 801 is fixedly arranged at the top of the side plate 8. A bolt 802 is threadedly connected to the top of the convex plate 801. A fixing plate 803 is fixedly connected to the bottom of the convex plate 801. A scraping plate 804 is fixedly connected to the surface of the fixing plate 803. An arc groove 9 is opened on the back surface of the movable measuring rod 3.

[0023] One long plate 7 and one side plate 8 are symmetrically arranged on both sides of the measuring instrument 1 respectively. Two grooves that match the surface shape of the movable measuring rod 3 are opened at the center of the side plate 8. The bolt 802 passes through the convex plate 801 and contacts the fixing plate 803. The shape of the slot 701 is larger than the shape of the bolt 802 at the top of the convex plate 801. The bottom of the fixing plate 803 and the scraping plate 804 are in contact with the surface of the movable measuring rod 3. The shape of the arc groove 9 matches the shape of the scraping plate 804.

[0024] Specific implementation method: First, when it is necessary for the measuring instrument 1 to measure a deeper gap, it is necessary to pull out the bolt 601 before the measuring instrument 1 enters the gap. Then, rotate the position of the sleeve 502 so that the sleeve 502 rotates at the positions of the rotating blocks 403 on both sides along the rotating rod 404 connected to the electric telescopic rod 501 and the connecting block 5, making the position of the sleeve 502 vertical. Then, pass the bolt 601 through the clamping block 6 and contact the rotated rotating block 403, so that the rotated position of the sleeve 502 is fixed. At the same time, place the measuring instrument 1 in the gap, start the electric telescopic rod 501, so that the electric telescopic rod 501 deepens the position of the measuring instrument 1 into the gap. Then, start the movable measuring rod 3 to make the abutting plate 301 contact the inner wall of the gap. At the same time, the parameters on the surface of the screen 2 can be observed, so as to complete the measurement of the deeper gap when the staff's arm cannot enter the gap;

[0025] Secondly, when it is necessary to prevent the surface soil from being retracted together when the movable measuring rod 3 contracts, the long plate 7 and the side plate 8 need to be installed on the side of the measuring instrument 1 before using the measuring instrument 1. At the same time, the fixing plate 803 and the scraping plate 804 at the bottom of the long plate 7 are in contact with the surface of the movable measuring rod 3. At this time, when the movable measuring rod 3 contracts, due to the contact between the scraping plate 804 and the surface of the movable measuring rod 3, the soil on the surface of the movable measuring rod 3 can be scraped off by the movable measuring rod 3. At the same time, the arc groove 9 on the back side of the abutting plate 301 is in contact with the scraping plate 804, so that the recovery of the abutting plate 301 will not be affected by the scraping plate 804. In this way, it can be ensured that the normal use of the movable measuring rod 3 is not affected by the surface soil being retracted together when the movable measuring rod 3 contracts.

[0026] Although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
