Description

Technical Field

[0001] The present invention relates to the technical field of wall detection, and particularly to an external wall detection device for construction projects. Background Art

[0002] In the construction industry, after a building is completed, in order to ensure that the construction quality meets the standards, it is necessary to measure the building. For example, when detecting a wall, it is necessary to detect the flatness of the external wall. When detecting the flatness of the wall, a laser ranging device is generally used to detect the wall.

[0003] In the prior art, such as a wall flatness detector for construction with the application number 202321548338.1, in which, by using a wall flatness detection component composed of a threaded rod, a lifting seat, an infrared ranging sensor and a motor, the distance from the wall can be measured from bottom to top by using the infrared ranging sensor, and then an accurate detection result can be obtained to judge whether the flatness of the wall at this place is qualified. The operation is convenient, and through the cooperation of the threaded rod and the motor, the ranging sensor can be lifted, and then different height positions of the wall can be measured. Since the external wall is generally relatively high, therefore, in order to cope with the flatness detection of higher external walls, the length of the threaded rod needs to be relatively long, and the lifting of too long a threaded rod will make the device large in volume, which is not conducive to practical use.

[0004] In view of the above technical problems, the present invention discloses an external wall detection device for construction projects. The present invention has the advantages that by arranging a plurality of rods to be butt-jointed with each other, and the laser ranging component is arranged at the end of the rod, then when in need of use, multiple rods can be butt-jointed, and when storing and transferring, the rods can be disassembled, so that the overall volume and total length are reduced, which is convenient for transfer and storage. And through the setting of the docking structure, the docking of multiple rods can be automatically carried out, which is convenient for operation. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an external wall detection device for construction projects, so as to solve the technical problems in the prior art that when detecting the flatness of a wall, in order to cope with the flatness detection of higher external walls, the length of the device needs to be relatively long, and too long a device will make the device large in volume, which is not conducive to practical use. The present invention has the advantages that by arranging a plurality of rods to be butt-jointed with each other, and the laser ranging component is arranged at the end of the rod, then when in need of use, multiple rods can be butt-jointed, and when storing and transferring, the rods can be disassembled, so that the overall volume and total length are reduced, which is convenient for transfer and storage. And through the setting of the docking structure, the docking of multiple rods can be automatically carried out, which is convenient for operation.

[0006] The present invention is achieved through the following technical solutions: The present invention discloses a detection device for the outer wall of a construction project, including a base and a guiding seat arranged above the base. A chute is vertically and penetratingly formed inside the guiding seat, and the chute penetrates the base. An extension rod is inserted into the chute. One end of the extension rod passes through the guiding seat and the base, and a laser distance measuring component is installed at the end of the extension rod below the base.

[0007] The extension rod is formed by docking at least two rod bodies, and adjacent two rod bodies are connected in a detachable manner. The laser distance measuring component is installed at the end of the lowest rod body. A docking mechanism is arranged at the guiding seat, and the docking mechanism is used for docking the rod bodies entering the inside of the chute. Adjacent two rod bodies are snap-connected through a connecting component.

[0008] The connecting component includes an insertion block, a slot, a plug-in body, and a snap groove. The bottom of the rod body is fixedly provided with an insertion block, and a slot for the insertion block to be inserted and matched is formed at the top of the rod body. Plug-in bodies are movably arranged on the front end face and the rear end face of the insertion block, and the connection between the plug-in body and the insertion block is elastically telescopic. Snap grooves for the plug-in body to be inserted and matched are respectively formed on the outer walls of the front end and the rear end of the slot.

[0009] The docking mechanism includes a conveying wheel and a driving component. A conveying wheel is rotatably installed on one inner wall of the chute, and the conveying wheel contacts the rod body for conveying the rod body. Two conveying wheels are provided and arranged longitudinally. A driving component for driving the conveying wheel is also arranged on the guiding seat.

[0010] Further, the part of the plug-in body located outside the insertion block is set as an inclined surface, and the tip is downward. A limiting block is arranged on one side of the top of the rod body, and a limiting groove for the limiting block to be inserted and matched is formed on one inner wall of the bottom of the chute. The limiting block is elastically telescopic on one side of the top of the rod body, and the contraction of the limiting block is controlled by an unlocking piece. The unlocking piece is arranged at the top inside the slot, and the unlocking piece is triggered by the insertion of the insertion block into the slot. The conveying wheel is set in a horizontally movable state and is controlled to move by an electric push rod. The electric push rod is electrically controlled by a controller. An inductor is also installed on the bottom wall of the limiting groove. Both the electric push rod and the inductor are electrically connected to the controller. When the limiting block enters the limiting groove and contacts the lower inductor, the electric push rod is triggered and controlled.

[0011] Further, a square groove is formed inside one side of the top of the rod body. A through groove is formed on the side wall of the square groove facing the outside, and the through groove penetrates the side wall of the rod body. A pressing plate is slidably inserted into the square groove. The limiting block is inserted into the through groove and is fixedly connected to one end of the pressing plate. A first spring is arranged on the other side of the pressing plate for rebounding the pressing plate towards the outside. The part of the limiting block located outside the rod body is set as an inclined surface, and the tip is upward. The two conveying wheels are respectively independently controlled to move by two electric push rods.

[0012] Further, the unlocking member includes a top plate, a second spring, and a connecting rope. The top plate is disposed inside the slot, and a second spring is disposed below the top plate for elastic support. The top plate and the pressing plate are connected by a connecting rope. When the top plate moves downward, the pressing plate is driven to move toward the inner side of the square groove through the connecting rope, driving the limiting block to contract.

[0013] Further, an installation groove is formed in the side wall of the chute where the conveying wheel is provided. An installation block is horizontally slidably disposed inside the installation groove. The conveying wheel is disposed inside the installation groove, and the wheel shaft of the conveying wheel is rotatably connected to the installation block. A relief groove for the wheel shaft is formed at the rear end of the installation groove, and the relief groove is elongated. The other end of the wheel shaft passes through the relief groove and extends to the rear end of the guiding seat. A sliding plate is disposed at one end of the wheel shaft located at the rear end of the guiding seat, and the sliding plate is slidably disposed at the rear end of the guiding seat. An electric push rod is installed at the rear end of the guiding seat, and the output shaft is fixedly connected to the sliding plate for controlling the movement of the sliding plate. The driving assembly includes a driving shaft, a gear set, a driven shaft, a rotating shaft, a connecting shaft, and a driving motor. The driving shaft is longitudinally rotatably disposed at the rear end of the guiding seat through a bearing seat and is rotationally driven by the driving motor. The top and bottom of the driving shaft are respectively meshed and connected with a driven shaft through a gear set. The driven shaft is horizontally rotatably installed at the rear end of the guiding seat through a bearing seat. A rotating shaft is horizontally rotatably disposed at the rear end of the sliding plate through a bearing seat. One end of the wheel shaft located at the rear end of the guiding seat passes through the sliding plate and is meshed and connected with one end of the rotating shaft through a gear set. Connecting shafts are fixedly disposed at the opposite ends of the driven shaft and the rotating shaft, and the connecting shaft is slidably inserted and matched with one end of the rotating shaft. The connecting shaft is polygonal.

[0014] Further, the side wall of the top opening of the chute corresponding to the limiting block is provided with an inclined surface.

[0015] Further, an activity groove is formed inside the rod body, and the activity groove penetrates through the rod body and the surface of the rod body facing the conveying wheel. An activity plate is longitudinally movably disposed inside the activity groove. A support member is disposed above the activity plate, and the support member is an elastic member. The upper and lower ends of the support member are respectively in contact with the activity plate and the top wall of the activity groove for supporting the activity plate and simultaneously rebounding the activity plate downward. A disassembling plate is longitudinally movably disposed on the surface of the rod body in contact with the conveying wheel. The disassembling plate is fixedly connected to one end of the activity plate. A block groove is formed inside the insertion block, and extension grooves are respectively formed at the front end and the rear end of the block groove. A moving block is movably disposed inside the block groove, and there are two moving blocks. Elastic members are respectively disposed on the opposite sides of the two moving blocks for rebounding the moving blocks toward the extension grooves. The insertion body is slidably inserted inside the extension groove and is fixedly connected to one end of the moving block. The contraction of the insertion body is controlled by the upward movement of the activity plate.

[0016] Further, two guiding columns are fixedly disposed inside the block groove. Control ropes are fixedly connected to the opposite sides of the two moving blocks, and the other ends of the control ropes extend upward through the guiding of the guiding columns and are fixedly connected to the activity plate.

[0017] Further, the conveying wheel is set as a gear, and the surface of the disassembling plate in contact with the conveying wheel is provided with teeth meshing with the conveying wheel. The rotational speed of the conveying wheel above the inner part of the sliding groove is greater than that of the conveying wheel below. A storage box is further arranged above the base for storing the disassembled rod bodies.

[0018] The present invention has the following advantages:

[0019] In the present invention, an extension rod is provided to hoist the laser distance measuring component. Thus, when detecting the flatness of the exterior wall, the laser distance measuring component can be lifted and lowered through the extension rod. The extension rod is set to be composed of multiple rod bodies detachably connected. Thus, when transfer and storage are required, the extension rod can be disassembled to avoid the extension rod being too long, which is convenient for transfer and storage. At the same time, by setting the guiding seat and the docking mechanism, the extension rod can be lifted and lowered steadily under the guidance of the guiding seat, making the lifting of the laser distance measuring component more stable. And through the setting of the conveying wheel, the lifting of the laser distance measuring component can be automatically and uniformly carried out. And when disassembling and assembling the extension rod are needed, the disassembly and docking of two adjacent rod bodies can be automatically completed inside the guiding seat during the conveying process of the rod bodies. When docking, the operator only needs to insert the rod body into the inner part of the sliding groove. While when disassembling, the operator only needs to take out the rod body, making the docking and disassembly of the extension rod simpler and simplifying the work. Description of the Drawings

Specific embodiments

[0034] The following gives a detailed description of the embodiments of the present invention. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating orientation or position relationship such as "front", "rear", "left", "right", etc. are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention.

[0035] The embodiment discloses a building engineering exterior wall detection device, as Figures 1 - 13As shown, it includes a guiding seat 2, such as Figure 1 and Figure 3 As shown, a sliding groove 3 is formed inside the guiding seat 2, and the sliding groove 3 runs through the upper and lower end faces of the guiding seat 2. An extension rod 4 is inserted into the sliding groove 3 inside the guiding seat 2. A base 1 is also provided at the bottom of the guiding seat 2. A sliding groove 3 is also formed at the center of the base 1 and runs through from top to bottom, so that one end of the extension rod 4 passes through the base 1 and the bottom surface of the guiding seat 2 and extends downward. A laser distance measuring component 5 is installed at one end of the extension rod 4 below the base 1 and the guiding seat 2. It should be noted that the laser distance measuring component 5 and the extension rod 4 are set to be detachably connected, and specifically can be configured to be detachably connected by means of screw thread connection. When it is necessary to detect the flatness of the exterior wall, the operator can place the base 1 on the top of the exterior wall on the roof, and make the extension rod 4 extend from top to the ground. Then, the extension rod 4 is guided downward through the sliding groove 3 on the guiding seat 2 and the laser distance measuring component 5 is turned on in advance, and then the laser distance measuring component 5 is moved downward on the exterior wall from top to bottom to detect the flatness of the exterior wall;

[0036] It should be noted that a suction cup 6 component or other fixing components can be provided at the bottom of the base 1, or a tripod or other chassis can be provided, and it is set to have a leveling function. Since this is an existing technology, it will not be described in the text. By setting, the base 1 can be fixed on the rooftop. In addition, the base 1 can also be set on a slide rail, and then the base 1 can be moved on the rooftop.

[0037] In actual use, the length of the extension rod 4 needs to be relatively long so as to detect exterior walls with a relatively high height. However, when the length of the extension rod 4 is too long, it will not be convenient to carry and store. When hoisting the laser distance measuring component 5 with a flexible tool such as a suspension rope, there will be a situation where the suspension rope is prone to shaking, which affects the position stability of the laser distance measuring component 5 and further affects the detection accuracy;

[0038] Therefore, to solve the above defects, in this embodiment, as Figure 1 and 2 As shown, the extension rod 4 is set to be composed of multiple rod bodies 401 connected together, and adjacent two rod bodies 401 are connected by a detachable connection method. The laser distance measuring component 5 is installed at the end of the lowest section. Then, when in use, by connecting the multiple rod bodies 401, a relatively long extension rod 4 is formed. By controlling the extension rod 4, the laser distance measuring component 5 is moved to detect the flatness of the exterior wall. When it is necessary to store or transfer, the multiple rod bodies 401 can be disassembled, so that the extension rod 4 is decomposed into multiple rod bodies 401 with relatively short lengths, thereby reducing the total length of the device and facilitating storage and transfer;

[0039] Considering that during operation, when the operator docks and disassembles the rod body 401, the large quantity makes the disassembly and docking troublesome. In order to automatically complete the assembly and disassembly of the extension rod 4 and make the detection work more convenient, in this embodiment, as Figures 1 - 3 shown, a docking mechanism 9 is provided at the guide seat 2, and the docking method of two adjacent rod bodies 401 is set as snap docking. The docking mechanism 9 automatically completes the assembly and disassembly of the rod body 401, making the operation more convenient;

[0040] Specifically, a connecting component 10 is provided between two adjacent rod bodies 401, so that the two rod bodies 401 are detachably connected by a snap. More specifically, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, the connecting component 10 includes an insertion block 101, a slot 102, an insertion body 103 and a snap groove 104. Among them, the insertion block 101 is fixedly arranged at the bottom of the rod body 401. Correspondingly, a slot 102 for the insertion block 101 to be inserted and matched is opened at the top of the rod body 401. The insertion block 101 is slidably inserted and matched with the slot 102. The front end face and the rear end face of the insertion block 101 are both provided with insertion bodies 103. The insertion bodies 103 are movably connected to the insertion block 101 and elastically telescoped by an elastic member 34. The front end and the rear end outer walls of the slot 102 are respectively provided with snap grooves 104 for the insertion bodies 103 to be inserted and matched. After the insertion block 101 of the upper rod body 401 is inserted into the slot 102 of the lower rod body 401, the insertion bodies 103 will be inserted into the snap grooves 104, thereby connecting the two rod bodies 401;

[0041] It should be noted that the part of the insertion body 103 located outside the insertion block 101 is set as an inclined surface, and specifically set with the tip facing downwards, so that when the insertion block 101 is inserted from the top opening of the slot 102, the insertion body 103 can be compressed and contracted first through the setting of the inclined surface of the insertion body 103, and then when the insertion body 103 is aligned with the snap groove 104, the insertion body 103 will bounce and then be inserted into the snap groove 104.

[0042] As Figure 1 、 Figure 3 、 Figure 4 and Figure 8As shown, the docking mechanism 9 includes a conveying wheel 901 and a driving assembly 902. Among them, the conveying wheel 901 is rotatably installed on one inner wall of the chute 3, and there are two conveying wheels 901. The two conveying wheels 901 are longitudinally arranged on one inner wall of the chute 3. Correspondingly, a driving assembly 902 for driving the conveying wheel 901 is also provided outside the guiding seat 2. Thus, when docking the rod body 401, the rod body 401 is inserted into the top opening of the chute 3, and then the rod body 401 is conveyed downward by the rolling of the conveying wheel 901. At the same time, another rod body 401 is inserted into the top opening, and through the conveyance of the conveying wheel 901, the two rod bodies 401 contact at one end facing each other inside the chute 3 and are docked;

[0043] In this embodiment, as Figure 2 and Figure 3 shown, the conveying wheel 901 is specifically set as a gear. Correspondingly, teeth 11 that are meshed with the conveying wheel 901 are provided on one side of the rod body 401 facing the conveying wheel 901;

[0044] It should be noted that the width of the chute 3 is set to be greater than the width of the rod body 401, and the front and rear end faces of the rod body 401 are respectively in contact with and slidably matched with the front and rear end faces of the chute 3. In addition, the side wall of the rod body 401 opposite to the conveying wheel 901 is also in contact with and slidably matched with the corresponding side wall of the chute 3, while there is a distance between the side wall of the rod body 401 facing the conveying wheel 901 and the inner wall of the chute 3 where the conveying wheel 901 is provided. The wheel surface of the conveying wheel 901 is in contact with the side of the rod body 401 facing it. Thus, the rod body 401 is conveyed downward by the rotation of the conveying wheel 901;

[0045] In addition, in order to enable the two rod bodies 401 to be docked inside the chute 3 and limit the rod body 401 to prevent the rod body 401 from directly falling downward from the chute 3, as Figure 3 、 Figure 4 and Figure 6 shown, a limiting block 12 is provided on one side of the top of the rod body 401. Correspondingly, a limiting groove 13 is opened on one inner wall of the bottom inside the chute 3. The limiting groove 13 and the limiting block 12 are arranged in the same direction. Thus, when the rod body 401 is inserted into the chute 3, the rod body 401 can be limited to prevent the rod body 401 from directly falling;

[0046] Furthermore, the limiting block 12 is elastically and movably installed on one side of the top of the rod body 401, and the contraction of the limiting block 12 is controlled by an unlocking member 14. The unlocking member 14 is arranged at the top inside the slot 102. Specifically, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown in the figure, a square groove 15 is formed inside one side of the top of the rod body 401. A through groove 16 is formed on the side wall of the square groove 15 facing the outside. The square groove 15 communicates with the outside through the through groove 16. A pressing plate 17 is slidably inserted inside the square groove 15. A limiting block 12 is inserted inside the through groove 16 and one end is fixedly arranged on the outer wall of the pressing plate 17 facing the through groove 16. A first spring 18 is arranged on the other side of the pressing plate 17. The first spring 18 is located between the pressing plate 17 and the inner wall of the square groove 15 and is used to bounce the pressing plate 17 towards the outside. Thus, the limiting block 12 can elastically expand and contract through the arrangement of the pressing plate 17 and the first spring 18. In addition, a part of the limiting block 12 located outside the rod body 401 is set as an inclined surface, which is narrow at the top and wide at the bottom with the tip facing upwards. Thus, the rod body 401 will be limited by the insertion of the limiting block 12 and the sliding groove 3 from top to bottom. When the rod body 401 moves from bottom to top, the inclined surface will cause the limiting block 12 to be squeezed and contract;

[0047] As Figure 6 and Figure 7 shown, the unlocking member 14 includes a top plate 141, a second spring 142 and a connecting rope 143. Among them, the top plate 141 is arranged inside the slot 102. A second spring 142 is arranged below the top plate 141. The second spring 142 is used to bounce the top plate 141 upwards. In addition, the top plate 141 and the pressing plate 17 are connected by a connecting rope 143. Specifically configured as, when the top plate 141 moves downwards, the top plate 141 will move the pressing plate 17 towards the inside of the square groove 15 through the connecting rope 143, causing the limiting block 12 to contract;

[0048] In addition, the conveying wheel 901 is also set to move horizontally through the electric push rod 36. In addition, the electric push rod 36 is controlled by setting a central controller. As Figure 1 、 Figure 4 and Figure 9 shown, the electric control box 8 of the controller is installed above the base 1. An inductor 37 is also installed on the bottom wall of the limiting groove 13. The inductor 37 can be set as a proximity switch. The electric push rod 36 and the inductor 37 are both electrically connected to the main controller. It should be noted that the two conveying wheels 901 are independently controlled to move through two electric push rods 36 respectively;

[0049] Specifically, as Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown in the figure, an installation groove 38 is formed in the side wall of the chute 3 where the conveying wheel 901 is provided. An installation block 19 is horizontally slidably arranged inside the installation groove 38. The conveying wheel 901 is arranged inside the installation groove 38, and the wheel shaft 22 of the conveying wheel 901 is rotatably connected to the installation block 19. By moving the installation block 19, the horizontal movement of the conveying wheel 901 is controlled. By moving the conveying wheel 901, the contact and separation between the conveying wheel 901 and the rod body 401 are controlled. More specifically, the installation block 19 is movably arranged inside the installation groove 38 through a dovetail groove 20 and a dovetail slider 21. Correspondingly, a relief groove 23 for the wheel shaft 22 to pass through is formed at the rear end of the installation groove 38, and the relief groove 23 is arranged in a long strip shape, so that the wheel shaft 22 has a horizontal movement space. The other end of the wheel shaft 22 passes through the relief groove 23 and extends to the rear end of the guide seat 2. A sliding plate 24 is arranged at one end of the wheel shaft 22 located at the rear end of the guide seat 2, and the sliding plate 24 is also slidably arranged at the rear end of the guide seat 2 through the cooperation of a dovetail groove 20 and a dovetail slider 21. The electric push rod 36 is installed at the rear end of the guide seat 2, and one end of the telescopic output shaft of the electric push rod 36 is fixedly connected to the outer wall of the sliding plate 24;

[0050] In addition, the driving assembly 902 includes a driving shaft 921, a gear set 922, a driven shaft 923, a rotating shaft 924, a connecting shaft 925 and a driving motor 926. Among them, the driving shaft 921 is rotatably arranged at the rear end of the guide seat 2 through a bearing seat. A driving motor 926 is installed at the bottom of the guide seat 2, and the output end of the driving motor 926 is drivingly connected to one end of the driving shaft 921. The driving shaft 921 is longitudinally arranged. The top and bottom of the driving shaft 921 are respectively meshed and connected with a driven shaft 923 through a gear set 922. The driven shaft 923 is also rotatably installed at the rear end of the guide seat 2 through a bearing seat, and the driven shaft 923 is horizontally arranged. A rotating shaft 924 is rotatably arranged at the rear end of the sliding plate 24 through a bearing seat, and the rotating shaft 924 is horizontally arranged. When the sliding plate 24 moves, the rotating shaft 924 can be driven to move horizontally. One end of the wheel shaft 22 located at the rear end of the guide seat 2 passes through the sliding plate 24 and is meshed and connected with one end of the rotating shaft 924 through a gear set 922, and the wheel shaft 22 is rotatably connected to the sliding plate 24. In addition, a connecting shaft 925 is fixedly arranged at the opposite ends of the driven shaft 923 and the rotating shaft 924, and the connecting shaft 925 is slidably inserted and matched with one end of the rotating shaft 924. The connecting shaft 925 is arranged in a polygon. In this embodiment, the specific cross-section is arranged as a quadrilateral;

[0051] Specifically, under normal conditions, the upper conveying wheel 901 retracts into the installation groove 38 to prevent the upper conveying wheel 901 from contacting the rod body 401 that enters the chute 3. The lower conveying wheel 901 extends into the chute 3, enabling the lower conveying wheel 901 to contact the rod body 401 that enters the chute 3. After the bottom surface of the limit block 12 contacts the inductor 37 inside the limit groove 13, it will trigger the controller to move the lower electric push rod 36 in a direction away from the chute 3, causing the lower conveying wheel 901 to move away from the rod body 401. At the same time, it will control the upper electric push rod 36 to move towards the chute 3, causing the upper conveying wheel 901 to contact the rod body 401;

[0052] Therefore, through the above settings, when it is necessary to dock the rod body 401, the operator only needs to insert the rod body 401 into the chute 3 in sequence from the top opening of the chute 3. It should be noted that to prevent the limit block 12 from affecting the insertion of the rod body 401, such as Figure 3 and Figure 4As shown in the figure, the side wall of the top opening of the sliding groove 3 corresponding to the limiting block 12 is set as an inclined surface, so that the rod body 401 can be inserted smoothly. Under normal conditions, through the control of the electric push rod 36, the upper conveying wheel 901 is moved to be separated from the rod body 401, and the lower conveying wheel 901 is moved to be in contact with the rod body 401. After the rod body 401 is inserted, the rod body 401 will directly move downward by gravity to contact the conveying wheel 901. Then, by starting the driving motor 926, the driving shaft 921 drives the two driven shafts 923 to rotate. The driven shaft 923 drives the rotating shaft 924 to rotate through the connecting shaft 925. The rotation of the rotating shaft 924 drives the wheel shaft 22 to rotate, so that the conveying wheel 901 rotates. The rotation of the lower conveying wheel 901 conveys the rod body 401 downward. As the rod body 401 moves downward inside the sliding groove 3, the limiting block 12 on one side of the rod body 401 will move to the limiting groove 13. At this time, the lower rod body 401 is under the upper conveying wheel 901, and the subsequent rod body 401 is still on one side of the upper conveying wheel 901. When the limiting block 12 moves to be flush with the limiting groove 13, the limiting block 12 will rebound due to the loss of the extrusion of the side wall of the sliding groove 3, and the limiting block 12 will be inserted into the limiting groove 13. It should be noted here that the height of the limiting groove 13 is greater than the height of the limiting block 12. Therefore, after the limiting block 12 is inserted into the limiting groove 13, the limiting block 12 will move downward synchronously with the continuous downward movement of the rod body 401. Then, the limiting block 12 will contact the bottom wall of the limiting groove 13 to limit the rod body 401, thereby preventing the rod body 401 from falling directly, and playing an insurance role through the limiting block 12. When the limiting block 12 moves downward to contact the bottom wall of the limiting groove 13, the limiting block 12 will contact the sensor 37 on the bottom wall of the limiting groove 13, so as to control the separation of the lower conveying wheel 901 from the rod body 401 and stop the downward movement of the rod body 401. The upper conveying wheel 901 moves to contact the upper rod body 401, and the upper conveying wheel 901 rotates to convey the upper rod body 401 downward, so that the upper rod body 401 moves downward, and the lower rod body 401 remains stationary. The downward movement of the upper rod body 401 will cause the insertion block 101 to be inserted into the insertion slot 102, and the plug-in body 103 will be inserted into the buckle slot 104 to connect the two rod bodies 401;

[0053] In addition, further, the height of the buckle groove 104 is set to be greater than the height of the insertion body 103. Therefore, after the insertion body 103 is inserted into the buckle groove 104, the upper rod body 401 can continue to move downward. The insertion block 101 below the upper rod body 401 will contact the lower top plate 141, and then the top plate 141 will move downward. The downward movement of the top plate 141 drives the pressing plate 17 to move inward through the connecting rope 143, causing the limiting block 12 to contract into the square groove 15, and further separating the limiting block 12 from the limiting groove 13. After the limiting block 12 is separated from the limiting groove 13, the sensor 37 emits a signal to control the reset operation of the upper and lower electric push rods 36. Then, the lower conveying wheel 901 continues to rotate to control the downward movement of the docked rod body 401. Then, the docking of the rod body 401 is completed in sequence, and at the same time, the extension rod 4 is controlled to extend downward, causing the laser ranging component 5 to move downward to detect the flatness of the outer wall.

[0054] When the laser ranging component 5 needs to be moved upward, only need to reverse the driving motor 926, so that the rod body 401 moves upward and drives the laser ranging component 5 to move upward.

[0055] And in order to complete the automatic disassembly of the extension rod 4, as Figure 12 shown, an activity groove 26 is also opened inside the rod body 401, and the activity groove 26 penetrates the side of the rod body 401 facing the conveying wheel 901. An activity plate 27 is longitudinally movably arranged inside the activity groove 26. A support member 28 is arranged above the activity plate 27, and the support member 28 is set as an elastic member. In this embodiment, it is specifically set as a spring. The upper and lower ends of the support member 28 are respectively in contact with the activity plate 27 and the top wall of the activity groove 26. The support member 28 is used to support the activity plate 27 and bounce the activity plate 27 downward at the same time. The side of the rod body 401 in contact with the conveying wheel 901 is set to be in a longitudinally movable state. Specifically, as Figure 1 、 Figure 2 and Figure 12 shown, a disassembly plate 29 is arranged on the side of the rod body 401 in contact with the conveying wheel 901, and the disassembly plate 29 is longitudinally slidably arranged on one side of the rod body 401 through a dovetail groove 20 and a dovetail slider 21. The disassembly plate 29 is fixedly connected to one end of the activity plate 27. In addition, it should be noted that when the rod body 401 is inserted into the chute 3, the outer wall of the disassembly plate 29 is in contact with the conveying wheel 901. Since the conveying wheel 901 is set as a gear, teeth 11 are arranged on the side of the disassembly plate 29 facing the conveying wheel 901;

[0056] Specifically, as Figure 2 and Figure 5As shown, a clamping block groove 30 is formed inside the insertion block 101. Extension grooves 31 are respectively formed at the front end and the rear end of the clamping block groove 30. The extension grooves 31 before and after the clamping block groove 30 penetrate through the front end face and the rear end face of the insertion block 101 respectively. A baffle 32 is fixedly arranged at the center inside the clamping block groove 30. Moving blocks 33 are respectively arranged at the front end and the rear end of the baffle 32. The moving blocks 33 are slidably inserted and matched with the clamping block groove 30. Elastic members 34 are respectively arranged on the opposite sides of the two moving blocks 33 facing the baffle 32. The other ends of the elastic members 34 are in contact with the baffle 32. The elastic members 34 are used to bounce the moving blocks 33 towards the extension grooves 31. The elastic members 34 are specifically springs. The insertion body 103 is slidably inserted inside the extension groove 31 and one end is fixedly connected with the moving block 33. The other end of the insertion body 103 extends to the outside of the insertion block 101;

[0057] In order to facilitate the disassembly of two adjacent rod bodies 401, guide columns 35 are further arranged at the front end and the rear end of the baffle 32. The guide columns 35 are fixedly connected with the inner wall of the buckle groove 104. Control ropes 25 are fixedly connected to the opposite sides of the two moving blocks 33. The other ends of the control ropes 25 extend upward through the guiding of the guide columns 35 and are fixedly connected with the movable plate 27. When the movable plate 27 moves upward, it can drive the moving blocks 33 to move towards the baffle 32, thereby causing the insertion body 103 to contract and releasing the docking of the two rod bodies 401;

[0058] It should also be noted that when the extension rod 4 needs to be disassembled, the operator can operate the upper electric push rod 36 alone, so that the upper conveying wheel 901 moves to the inside of the chute 3 and can contact the rod body 401 inside the chute 3, so that both the upper and lower conveying wheels 901 can convey the rod body 401. In addition, in this embodiment, as Figure 8 shown, by configuring the gear sets 922 at the upper and lower drive shafts 921, the rotation speed of the upper conveying wheel 901 is greater than that of the lower conveying wheel 901.

[0059] With the above settings, when it is necessary to disassemble the extension rod 4, only need to control the driving motor 926 to reverse the conveyor wheel 901, and at the same time control the upper electric push rod 36 to move the upper conveyor wheel 901 to the inside of the chute 3 to contact the rod body 401 inside the chute 3, so that both the upper and lower conveyor wheels 901 can convey the rod body 401. Therefore, when the conveyor wheel 901 reverses, first the lower conveyor wheel 901 will convey the lower rod body 401 upward. Since the limit block 12 is elastically arranged, the elastic block will be contracted and will not affect the upward movement of the rod body 401. When the rod body 401 rises to contact the upper conveyor wheel 901, it should be noted here that the distance between the two conveyor wheels 901 is greater than the length of the rod body 401. When the rod body 401 rises and contacts the upper conveyor wheel 901, the upper rod body 401 will move above the lower conveyor wheel 901 and separate from the lower conveyor wheel 901. The upper conveyor wheel 901 will convey the upper rod body 401, and the lower conveyor wheel 901 will convey the lower rod body 401. Since the rotation speed of the upper conveyor wheel 901 is greater than that of the lower conveyor wheel 901, the upper conveyor wheel 901 will give the upper rod body 401 an upward traction force. Since the disassembly plate 29 in contact with the conveyor wheel 901 is arranged to be slidable and elastically supported by the support member 28, when the two rod bodies 401 are butted, the upper conveyor wheel 901 will move the disassembly plate 29 upward relative to the rod body 401. The upward movement of the disassembly plate 29 will compress the support member 28 and at the same time move the moving blocks 33 in the two clamping block grooves 30 toward each other through the control rope 25, thereby causing the two plug-in bodies 103 to contract. When the two plug-in bodies 103 contract and separate from the buckle groove 104, due to the compression of the support member 28, the support member 28 will make the upper rod body 401 bounce upward through the elastic force and separate from the lower rod body 401. Then the operator only needs to take out the upper rod body 401, and thus the disassembly of the rod body 401 is automatically completed in turn during the reverse rotation of the conveyor wheel 901.

[0060] In addition, as Figure 1 and Figure 13 shown, a storage box 7 is also provided above the base 1 for storing the disassembled rod body 401. In another embodiment, the conveyor wheel 901 can be set as a roller, and the rod body 401 is conveyed by the friction between the roller and the disassembly plate 29.

[0061] The principle of the present invention is as follows: When the present invention is in use, the operator only needs to insert the rod body 401 into the inside of the chute 3 in sequence from the top opening of the chute 3. Under normal conditions, through the control of the electric push rod 36, the upper conveying wheel 901 is moved to be separated from the rod body 401, and the lower conveying wheel 901 is moved to be in contact with the rod body 401. After the rod body 401 is inserted, the rod body 401 will directly move downward by gravity to contact the conveying wheel 901. Then, by starting the driving motor 926, the driving shaft 921 drives the two driven shafts 923 to rotate. The driven shaft 923 drives the rotating shaft 924 to rotate through the connecting shaft 925. The rotation of the rotating shaft 924 drives the wheel shaft 22 to rotate, and further makes the conveying wheel 901 rotate. The rotation of the lower conveying wheel 901 will convey the rod body 401 downward. As the rod body 401 moves downward inside the chute 3, the limiting block 12 on one side of the rod body 401 will move to the limiting groove 13. At this time, the lower rod body 401 is below the upper conveying wheel 901, and the subsequent rod body 401 is still on one side of the upper conveying wheel 901. When the limiting block 12 moves to be flush with the limiting groove 13, the limiting block 12 will rebound due to the loss of the extrusion of the side wall of the chute 3. The limiting block 12 will be inserted into the inside of the limiting groove 13. The limiting block 12 will move downward synchronously as the rod body 401 continues to move downward. Then, the limiting block 12 will contact the bottom wall of the limiting groove 13 to limit the rod body 401, thereby preventing the rod body 401 from directly falling. The limiting block 12 plays an insurance role. When the limiting block 12 moves downward and contacts the bottom wall of the limiting groove 13, the limiting block 12 will contact the inductor 37 on the bottom wall of the limiting groove 13, thereby controlling the separation of the lower conveying wheel 901 from the rod body 401 and stopping the downward movement of the rod body 401. And the upper conveying wheel 901 moves to contact the upper rod body 401, and the upper conveying wheel 901 rotates to convey the upper rod body 401 downward, thereby making the upper rod body 401 move downward and the lower rod body 401 remain stationary. The downward movement of the upper rod body 401 will make the insertion block 101 inserted into the insertion slot 102, and the plug-in body 103 will be inserted into the buckle slot 104 to connect the two rod bodies 401. When it is necessary to disassemble the extension rod 4, only need to control the driving motor 926 to make the conveying wheel 901 reverse, and at the same time control the upper electric push rod 36 to make the upper conveying wheel 901 move into the chute 3 to be in contact with the rod body 401 inside the chute 3, so that both the upper and lower conveying wheels 901 can convey the rod body 401. Therefore, when the conveying wheel 901 reverses, first, the lower conveying wheel 901 will convey the lower rod body 401 upward. And because the limiting block 12 is elastically arranged, the elastic block will be contracted and will not affect the upward movement of the rod body 401. When the rod body 401 rises to contact the upper conveying wheel 901, after the rod body 401 contacts the upper conveying wheel 901, the upper rod body 401 will move above the lower conveying wheel 901 and be separated from the lower conveying wheel 901. The upper conveying wheel 901 will convey the upper rod body 401, and the lower conveying wheel 901 will convey the lower rod body 401.Since the rotational speed of the upper conveying wheel 901 is greater than that of the lower conveying wheel 901, the upper conveying wheel 901 will apply an upward traction force to the upper rod body 401. And since the disassembly plate 29 in contact with the conveying wheel 901 is arranged to be slidable and elastically supported by the support member 28, when the two rod bodies 401 are docked, the upper conveying wheel 901 will move the disassembly plate 29 upward relative to the rod body 401. The upward movement of the disassembly plate 29 will compress the support member 28 and at the same time move the moving blocks 33 inside the two clamping block grooves 30 toward each other through the control rope 25, thereby causing the two plug connectors 103 to contract. When the two plug connectors 103 contract and separate from the buckle grooves 104, due to the compression of the support member 28, the support member 28 will cause the upper rod body 401 to bounce upward and thus disassemble from the lower rod body 401. After that, the operator only needs to take out the upper rod body 401, and then the disassembly of the rod body 401 can be automatically completed in turn during the reverse rotation of the conveying wheel 901.
