Technical Field

[0001] The utility model belongs to the technical field of building main body detection, and particularly relates to a detection device for on-site detection of a building main structure. Background Art

[0002] A building's main structure refers to its primary components, including the load-bearing and protective structures. It is the core of a building, carrying the entire building's load and protecting the interior from the external environment. These components, including beams, columns, and walls, are responsible for carrying and distributing loads. Common main structures include reinforced concrete, steel, and masonry.

[0003] After searching the reference authorization document with the publication number of CN220472652U, a safety detection device for reinforced concrete building structures is disclosed. The device is started by a driving motor in the machine cavity, so that the output end of the driving motor drives the screw to rotate inside the adjustment cavity, and the upper end of the screw is connected to the inner side of the screw sleeve at the lower end of the adjusting rod through a thread, so that the adjusting rod can slide and retract on the adjusting cavity, which is convenient for adjusting the detection height of the steel bar scanner at the upper end of the adjusting rod. Therefore, it does not need to be based on the height adjustment structure of the vehicle body, ensuring detection flexibility and convenience of carrying.

[0004] Although the existing detection device can be driven by a motor to automatically and flexibly adjust the handheld rod on the device, because the device is equipped with some large accessories such as motors and batteries, it not only increases the weight of the device itself, making the device difficult to carry, but also increases the complexity of use and manufacturing cost of the device. Utility Model Content

[0005] The purpose of the utility model is to provide a detection device for on-site detection of the main structure of a building, which can quickly adjust the length of the handheld rod and flexibly detect the main structure of the building at a high place. At the same time, it can reduce the weight of the existing equipment through the cooperation of simple structures, making it easier to carry and maintain the equipment.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] The invention also provides a method for adjusting the position of the gear train, wherein the gear train is installed in a fixed position and the gear train is installed in a fixed position, wherein the gear train is installed in a fixed position and the gear train is installed in a fixed position.

[0008] Preferably, the tops of the gear rods are fixedly connected with protrusions, the inner walls of the gripping rods are fixedly connected with sliding rods, and the protrusions are fixedly connected to the surfaces of the sliding rods.

[0009] Preferably, a vertical slot is provided on the front side of the extension rod, and the rack is movably arranged inside the vertical slot.

[0010] Preferably, a handle is fixedly connected to the end of the gear rod, and the handle is in an arc shape.

[0011] Preferably, circular holes are provided on both sides of the gripping rod, and the diameters of the circular holes are adapted to the fixing rod.

[0012] Preferably, there are several fixing grooves, which are evenly distributed on both sides of the inner wall of the extension rod.

[0013] Preferably, the bottom end of the extension rod is fixedly connected to a handle, and the handle is made of rubber.

[0014] The technical effects achieved by this utility model are:

[0015] The utility model cooperates with the adjustment mechanism. When the detector is used and a building main body at a height needs to be inspected, the staff can pull the rack outward through the handle and squeeze the spring. The outward movement of the rack will drive the meshing rotating wheel and the circular shaft to rotate clockwise. The clockwise rotation of the circular shaft will also drive the gear to rotate clockwise. The clockwise rotation of the gear will drive the meshing gear rod to move inward at the same time. The inward movement of the gear rod will drive the fixing rod to move inward and make the fixing rod disengage from the inside of the fixing groove. Then, the extension rod can be pulled downward as needed to make the extension rod The long rod slides on the surface of the grip to extend the grip of the detector. When the appropriate length is adjusted, the hand is separated from the handle, and the gear rod and the fixed rod are pushed to move outward at the same time under the rebound force of the spring, and the fixed rod is connected with the fixed groove. The fixed rod can be limited inside the fixed groove under the elastic force of the spring, and the extension rod can be fixed and limited on the surface of the grip. Therefore, with the mutual cooperation of the adjustment mechanism, the length of the grip of the detector can be flexibly adjusted quickly. The structure is simple, which helps to reduce the weight of the detector itself and is convenient to carry.

[0016] When the gear rod moves, the gear rod drives the protrusions to move respectively. The protrusions slide on the surface of the slide rod when moving. The protrusions and the slide rod are connected in cooperation, which limits the parallel movement of the gear rod when moving, and prevents the gear rod from being displaced and disconnected from the gear when moving. In this way, the gear rod can be auxiliary limited, so that the adjustment mechanism can operate smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0023] like Figure 1-3As shown, a detection device for on-site detection of the main structure of a building includes a detector 1 and a handle 2, the handle 2 is connected to the top of the detector 1, the surface of the handle 2 is sleeved with an extension rod 3, the interior of the handle 2 is set as a cavity, and the interior of the handle 2 is provided with an adjustment mechanism; the adjustment mechanism includes a fixing groove 201, a circular shaft 202, a gear 203, a gear rod 204, a fixing rod 205, a rotating wheel 206, a rack 207 and a spring 208, the fixing groove 201 is opened on both sides of the inner wall of the extension rod 3, the circular shaft 202 is connected to the inner wall of the handle 2 through a bearing, the gear 203 is sleeved on the surface of the circular shaft 202, the gear rod 204 is meshed with the front and rear sides of the gear 203, and the fixing groove 201 is opened on both sides of the inner wall of the extension rod 3, the circular shaft 202 is connected to the inner wall of the handle 2 through a bearing, the gear 203 is sleeved on the surface of the circular shaft 202, and the gear rod 204 is meshed with the front and rear sides of the gear 203. One end of the fixed rod 205 is fixedly connected to the outside of the gear rod 204, the other end of the fixed rod 205 passes through the grip rod 2 and extends to the inside of the fixed groove 201, the rotating wheel 206 is sleeved on the surface of the circular shaft 202 and is located at the bottom of the gear 203, the rack 207 is meshed and connected to one side of the rotating wheel 206, one end of the rack 207 is movably set inside the grip rod 2, the other end of the rack 207 passes through the grip rod 2 and the extension rod 3 in sequence, and the other end of the rack 207 extends to the outside of the extension rod 3, one end of the spring 208 is fixedly connected to the inner wall of the grip rod 2, and the other end of the spring 208 is fixedly connected to the rack 207. Through the cooperation of the adjustment mechanism, when using the inspection When the measuring instrument 1 detects the position of the steel bars in the main body of the building and needs to detect the main body of the building at a high place, the staff can pull the rack 207 outward through the handle 5 and squeeze the spring 208. The outward movement of the rack 207 will drive the meshing rotating wheel 206 and the circular shaft 202 to rotate clockwise. The clockwise rotation of the circular shaft 202 will also drive the gear 203 to rotate clockwise. The clockwise rotation of the gear 203 will drive the meshing gear rod 204 to move inward at the same time. The inward movement of the gear rod 204 will drive the fixing rod 205 to move inward and make the fixing rod 205 disengage from the inside of the fixing groove 201. Then, the extension rod 3 is pulled downward as needed to make the extension rod 3 move downward. The long rod 3 slides on the surface of the grip 2 to extend the grip 2 of the detector 1. When the appropriate length is adjusted, the hand is separated from the handle 5, and the gear rod 204 and the fixed rod 205 are pushed to move outward at the same time under the rebound force of the spring 208, and the fixed rod 205 is connected with the fixed groove 201. The fixed rod 205 can be limited to the inside of the fixed groove 201 under the elastic force of the spring 208, and the extension rod 3 can be fixed and limited to the surface of the grip 2. Therefore, with the mutual cooperation of the adjustment mechanism, the length of the grip 2 of the detector 1 can be flexibly adjusted quickly. The structure is simple, which helps to reduce the weight of the detector 1 itself and is convenient to carry.

[0024] like Figure 2-3As shown, the top of the gear rod 204 is fixedly connected with a protrusion 209, the inner wall of the handle 2 is fixedly connected with a slide rod 210, and the protrusions 209 are fixedly connected to the surface of the slide rod 210. When the gear rod 204 moves, the gear rod 204 will drive the protrusions 209 to move respectively, and the protrusions 209 will slide on the surface of the slide rod 210 when moving. And under the cooperative connection between the protrusions 209 and the slide rod 210, the gear rod 204 can be limited to move in parallel when moving, preventing the gear rod 204 from being displaced and disconnected from the gear 203 when moving, thereby auxiliary limiting the gear rod 204, so that the adjustment mechanism can operate smoothly.

[0025] like Figure 1 As shown, a vertical groove 4 is provided on the front side of the extension rod 3, and the rack 207 is movably arranged inside the vertical groove 4. When the extension rod 3 slides on the surface of the handle 2, the rack 207 can cooperate with the vertical groove 4 to prevent the extension rod 3 from colliding with the rack 207 during movement, causing motion interference and affecting the normal operation of the adjustment mechanism.

[0026] like Figure 1-3 As shown, a handle 5 is fixedly connected to the end of the gear rod 204. The handle 5 is arc-shaped and can provide a convenient and comfortable gripping point for the staff to pull the rack 207 to operate the adjustment mechanism.

[0027] like Figure 2-3 As shown, circular holes 6 are provided on both sides of the grip 2, and the diameter of the circular holes 6 matches the fixed rod 205. When the fixed rod 205 moves, the fixed rod 205 can cooperate with the circular holes 6 to prevent the fixed rod 205 from getting stuck with the worm when moving, which makes the fixed rod 205 unable to move flexibly.

[0028] like Figure 2-3 As shown, there are several fixing grooves 201, which are evenly distributed on both sides of the inner wall of the extension rod 3. Under the action of multiple fixing grooves 201, the fixing rod 205 can be adapted and connected with the fixing grooves 201 of different heights, so as to flexibly adjust the length of the grip 2, thereby improving its flexibility and making the detector 1 more applicable.

[0029] like Figure 1-2 As shown, the bottom end of the extension rod 3 is fixedly connected with a handle 7, which is made of rubber. The handle 7 can provide a convenient gripping position for the staff, facilitate the operation and control of the detector 1, improve the comfort of the staff, and is suitable for long-term use and work.

[0030] The working principle of the present invention is as follows: the staff can pull the rack 207 outward through the handle 5 and squeeze the spring 208. The outward movement of the rack 207 will drive the meshing rotating wheel 206 and the circular shaft 202 to rotate clockwise. The clockwise rotation of the circular shaft 202 will also drive the gear 203 to rotate clockwise. The clockwise rotation of the gear 203 will drive the meshing gear rod 204 to move inward at the same time. The inward movement of the gear rod 204 will drive the fixing rod 205 to move inward and make the fixing rod 205 disengage from the inside of the fixing groove 201. Then, the extension rod 3 is pulled downward as needed to make the extension rod 3 slides on the surface of the grip 2 to extend the grip 2 of the detector 1. When the appropriate length is adjusted, the hand is separated from the handle 5, and the gear rod 204 and the fixed rod 205 are pushed outward at the same time under the rebound force of the spring 208, so that the fixed rod 205 is connected with the fixed groove 201. The fixed rod 205 can be limited inside the fixed groove 201 under the elastic force of the spring 208, and the extension rod 3 can be fixed and limited on the surface of the grip 2. Therefore, under the mutual cooperation of the adjustment mechanism, the length of the grip 2 of the detector 1 can be flexibly adjusted quickly, and the building main body at high place can be flexibly detected.
