Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically to a seismic stability monitoring device. Background Technology

[0002] After the completion of civil engineering buildings, seismic resistance level testing is required. The seismic resistance level, stability, and concrete strength of a building are directly related, so a rebound hammer is used to complete this test. A rebound hammer is an instrument used to measure the elastic recovery ability of materials and can be applied to the seismic stability monitoring of civil engineering buildings.

[0003] Chinese Patent No. CN220552685U discloses a seismic stability monitoring device for civil engineering buildings, including a rebound hammer body equipped with a monitoring screen, a shell sleeved around the rebound hammer body and elastically connected to the rebound hammer body; the rebound hammer body is also equipped with a rebound component.

[0004] In response to the aforementioned disclosed technology, existing technologies have improved the rebound spring, for example by using a shell to protect the pen tip and using an elastic connection to extend and retract the pen tip. This improvement enhances the safety and convenience of using the rebound spring. However, many existing shell designs still have certain defects, such as the lack of protective structures at the ends of the shell and the frustum-shaped support.

[0005] Therefore, a seismic stability monitoring device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a seismic stability monitoring device in order to solve the problems mentioned in the background art.

Opening and closing components are installed on both the left and right side walls of the rebound hammer body, and protective end caps are fixedly installed on the movable parts of the opening and closing components to allow the two sets of protective end caps to open and close.

[0009] Furthermore, the protective component includes a cylinder that is movably sleeved on the surface of the rebound hammer body, and a cover is fixedly installed at the bottom end of the cylinder. The left and right side walls of the cylinder are provided with through grooves, and the bottom surface of the cylinder is provided with a groove.

[0010] Furthermore, the elastic reset assembly includes a base plate fixedly installed at the bottom of the through groove, an L-shaped slider slidably installed inside the through groove, a spring fixedly installed on the top surface of the base plate and the bottom surface of the L-shaped slider, and bolts threaded into the inside of the L-shaped slider and the threaded recess on the surface of the rebound device body.

[0011] Furthermore, the opening and closing assembly includes a bidirectional threaded rod rotatably inserted into the left and right side walls of the cover, and a knob is fixedly installed at one end of the bidirectional threaded rod. The knob is located outside the cover. A smooth rod is fixedly installed on the left and right side walls of the cover. Two sets of threaded sleeve blocks are threadedly fitted on the surface of the bidirectional threaded rod. Two sets of guide sliders are slidably fitted on the surface of the smooth rod. Protective end caps are fixedly installed at the bottom ends of the two sets of threaded sleeve blocks and the guide sliders. The protective end caps are slidably installed in the groove.

[0012] Furthermore, the ends of both the base plate and the L-shaped slider are arc-shaped, and the arc-shaped ends of the base plate and the L-shaped slider are in contact with the surface of the rebound hammer body.

[0013] Furthermore, both sides of the through groove are provided with arc grooves, and both the front and rear sides of the L-shaped slider are provided with protrusions, which are slidably arranged in the arc grooves to guide the L-shaped slider vertically.

[0014] The beneficial effects of this utility model are as follows:

[0015] By attaching the end of the protective component to the surface of the engineering building, the two sets of protective end caps are opened by the opening and closing component. By pressing the rebound hammer body, the moving parts of the rebound hammer body and the elastic reset component are moved, compressing the elastic part of the elastic reset component. This causes the detection end of the rebound hammer body to contact the surface of the engineering building. The elastic part of the elastic reset component causes the moving parts of the rebound hammer body and the elastic reset component to retract into the interior of the protective component. The opening and closing component closes the two sets of protective end caps, thus providing comprehensive protection for the detection end of the rebound hammer body through the protective component and protective end caps, completely protecting the detection end of the rebound hammer body.

[0027] like Figures 1 to 6As shown, a seismic stability monitoring device includes a rebound hammer body 1, with threaded recesses 11 on both sides of the rebound hammer body 1. A protective component 2 is slidably fitted on the surface of the rebound hammer body 1. An elastic reset component 3 is fixedly installed on the rebound hammer body 1 and the protective component 2. Opening and closing components 4 are installed on both the left and right sides of the rebound hammer body 1, and protective end caps 5 are fixedly installed on the movable part of the opening and closing components 4 to allow the two sets of protective end caps 5 to open and close. More specifically, during assembly, the rebound hammer body 1 is inserted into the interior of the protective component 2, and the movable part of the elastic reset component 3 is fixed to the rebound hammer body 1. When monitoring the seismic stability of civil engineering structures, the end of the protective component 2 is placed against the surface of the building. The two sets of protective end caps 5 are opened using the opening and closing component 4. By pressing the rebound hammer body 1, the movable parts of the rebound hammer body 1 and the elastic reset component 3 are moved, compressing the elastic part of the elastic reset component 3. This causes the detection end of the rebound hammer body 1 to contact the surface of the building. The rebound hammer body 1 is... A certain pressure is applied and then released to measure the degree of recovery of the material after the pressure is released, as well as its elastic recovery energy. By measuring the rebound value, the elasticity of the foundation or ground of the engineering building can be understood, and its support capacity under seismic load can be evaluated. After the test is completed, the elastic part of the elastic reset component 3 causes the rebound hammer body 1 and the movable part of the elastic reset component 3 to retract into the interior of the protective component 2. The opening and closing component 4 closes the two sets of protective end caps 5, thereby enabling the protective component 2 and the protective end caps 5 to provide comprehensive protection for the detection end of the rebound hammer body 1, completely protecting the detection end of the rebound hammer body 1.

[0028] The protective component 2 includes a cylindrical body 201 that is movably fitted onto the surface of the rebound hammer body 1, and a cover 202 is fixedly installed at the bottom end of the cylindrical body 201. Through grooves 203 are provided on both the left and right side walls of the cylindrical body 201, and a groove 204 is provided on the bottom surface of the cylindrical body 201. More specifically, by fitting the cylindrical body 201 onto the surface of the rebound hammer body 1, the detection end of the rebound hammer body 1 is protected when the rebound hammer body 1 is not in use.

[0029] The elastic reset assembly 3 includes a base plate 301 fixedly installed at the bottom of the through groove 203, an L-shaped slider 302 slidably installed inside the through groove 203, a spring 304 fixedly installed on the top surface of the base plate 301 and the bottom surface of the L-shaped slider 302, and a bolt 303 threadedly inserted into the threaded recess 11 on the surface of the rebound device body 1 inside the L-shaped slider 302. More specifically, the rebound hammer body 1 is inserted into the interior of the cylinder 201, so that the threaded recess 11 and the L-shaped slider 302 on the surface of the rebound hammer body 1 are correspondingly set. The bolt 303 is inserted into the threaded recess 11 and the internal thread of the L-shaped slider 302, thereby fixing the L-shaped slider 302 and the surface of the rebound hammer body 1. During the test, pressing the rebound hammer body 1 causes the L-shaped slider 302 to move vertically downward along the interior of the through groove 203, thereby compressing the spring 304. After the test is completed, the spring force of the spring 304 causes the L-shaped slider 302 and the rebound hammer body 1 to move vertically upward, thereby causing the rebound hammer body 1 to retract into the interior of the cylinder 201 and the cover 202.

[0030] The opening and closing assembly 4 includes a bidirectional threaded rod 401 that is rotatably inserted into the left and right side walls of the cover 202, and a knob 402 is fixedly installed at one end of the bidirectional threaded rod 401. The knob 402 is located outside the cover 202. A smooth rod 403 is fixedly installed on the left and right side walls of the cover 202. Two sets of threaded sleeve blocks 404 are threadedly sleeved on the surface of the bidirectional threaded rod 401. Two sets of guide sliders 405 are slidably sleeved on the surface of the smooth rod 403. Protective end caps 5 are fixedly installed at the bottom ends of the two sets of threaded sleeve blocks 404 and the guide sliders 405. The protective end caps 5 are slidably installed in the groove 204. More specifically, the knob 402 drives the bidirectional threaded rod 401 to rotate, and the threaded sleeve 404 is threaded onto the bidirectional threaded rod 401, so that the two sets of protective end caps 5 move and open along the surface of the smooth rod 403 under the action of the guide slider 405. The two sets of protective end caps 5 are opened to allow the detection operation to be performed. After the detection is completed, the two sets of protective end caps 5 are closed to close the bottom end of the cylinder 201, thereby closing the end of the cover 202 and achieving comprehensive protection of the detection end of the rebound hammer body 1.

[0031] Both the base plate 301 and the L-shaped slider 302 have arc-shaped ends, and these arc-shaped ends are in contact with the surface of the rebound hammer body 1. More specifically, the arc-shaped ends of the base plate 301 and the L-shaped slider 302 enable limiting and guiding the rebound hammer body 1 as it moves relative to the cylinder 201.

[0032] Both sides of the through groove 203 are provided with arc grooves, and both the front and rear sides of the L-shaped slider 302 are provided with protrusions. The protrusions are slidably arranged in the arc grooves to guide the L-shaped slider 302 vertically. More specifically, by the sliding of the protrusions on the front and rear sides of the L-shaped slider 302 in the arc grooves on both sides of the through groove 203, the vertical movement of the L-shaped slider 302 can be guided and limited.

[0033] In summary: During assembly, the rebound hammer body 1 is inserted into the interior of the protective component 2, and the movable part of the elastic reset component 3 is fixed to the rebound hammer body 1. When monitoring the seismic stability of civil engineering structures, the end of the protective component 2 is placed against the surface of the building. The two sets of protective end caps 5 are opened using the opening and closing component 4. Pressing the rebound hammer body 1 causes the movable parts of the rebound hammer body 1 and the elastic reset component 3 to move, compressing the elastic part of the elastic reset component 3. This causes the detection end of the rebound hammer body 1 to contact the surface of the building. The rebound hammer body 1 is activated by applying... A certain pressure is applied and then released to measure the degree of material recovery and its elastic recovery energy after the pressure is released. By measuring the rebound value, the elasticity of the foundation or ground of the engineering building can be understood, and its support capacity under seismic load can be assessed. After the test is completed, the elastic part of the elastic reset component 3 causes the rebound hammer body 1 and the movable part of the elastic reset component 3 to retract into the interior of the protective component 2. The opening and closing component 4 closes the two sets of protective end caps 5, thereby achieving comprehensive protection of the detection end of the rebound hammer body 1 through the protective component 2 and the protective end caps 5, and completely protecting the detection end of the rebound hammer body 1.
