Description

Technical Field

[0001] The invention relates to the technical field of house safety, and in particular to a house safety identification device. Background Art

[0002] In the house safety appraisal, the tilt angle of the house is particularly important. Whether the house is old or undergoing renovation or after an earthquake, it is very necessary to appraise the house. At present, most of the existing house appraisal devices use electronic horizontal and vertical meters to detect the tilt of the wall. However, the device has a large error during detection. The manual detection device generally measures the angle through a detection ruler and sets it on a trolley. The trolley is moved to detect different positions. The trolley may affect the measurement data due to shaking or movement. The wheels of the trolley use self-locking universal wheels, but in the process of fixing the universal wheels, the trolley may still shake or slightly move due to external forces. At this time, it is necessary to move the trolley to adjust its relative position with the wall.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0040] refer to Figure 1-Figure 15 The present invention discloses a housing safety appraisal device, including a base plate 1, vertical plates 2 are arranged on both sides of the base plate 1, the base plate 1 is fixed at a position close to the middle of the vertical plates 2, and the vertical plates are arranged along the length direction of the base plate. A plurality of wheels 19 are arranged at the bottom of each vertical plate 2 through a bracket, and at least three wheels are arranged on a single side to avoid the situation that when only four wheels are arranged at the bottom of the base plate 1, the base plate of the entire device is tilted, shaken, or even cannot be fixed due to uneven ground. Therefore, multiple wheels are arranged, and even if a wheel cannot contact the ground, the base plate will not be unstable due to the existence of other wheels. A wheel fixing mechanism that can lock each wheel individually is arranged above the wheel 19, and the two wheel fixing mechanisms are linked by a switch to simultaneously lock the wheel 19. Based on the above situation, when locking the wheels, it is not possible to choose to lock a single wheel one by one, but all wheels should be locked at the same time.

[0041] Furthermore, the wheel fixing mechanism includes a fixing groove 20 arranged above the wheel 19 and corresponding to the wheel 19 one by one, a connecting rod 21 is connected to the top of the fixing groove 20, and the other end of the connecting rod 21 is connected to the linkage switch. The fixing groove is adapted to the wheel, the opening is arranged downward, and it is a whole, which can be understood as a fixing block having a groove corresponding to the wheel one by one as the fixing groove. When the wheel fixing mechanism moves downward, all wheels can be locked at the same time.

[0042] Furthermore, the linkage switch includes a through hole 22 provided on the bottom plate 1, a column 23 is provided through the through hole 22, both ends of the column extend out of the through hole, and the connecting rod 21 is fixed to the bottom end of the column 23 through a bearing, that is, the connecting rod is fixed to the outer ring of the bearing, and the column is fixed to the inner ring of the bearing, so that the column can rotate. A wedge block 24 with opposite directions is provided on the side wall of the end of the column 23 located above the bottom plate 1, that is, the inclined surfaces of the wedge block face opposite directions, and the wedge blocks with the same direction are preferably provided correspondingly, and the wedge blocks with different directions are provided along the length direction of the column. A groove 25 adapted to the wedge block 24 is provided through the inner wall of the through hole 22. As one of the implementation schemes, there are four wedge blocks, two facing the same direction and two facing opposite directions. The wedge blocks facing the same direction are symmetrically arranged. Similarly, the number of grooves is the same as the number of wedge blocks, and they are symmetrically arranged in pairs, so that the columns and wedge blocks can pass through. At the same time, the four wedge blocks are not at the same level, and two wedge blocks facing the same direction form a group. The two groups of wedge blocks are arranged along the length direction of the column. In this embodiment, if Figure 2 In the state shown, the end face of the upper wedge block faces upward, and the end face of the lower wedge block faces downward.

[0043] When in use, the column 23 is pressed to pass through the through hole 22, and then the column 23 is rotated so that the end faces of the top of the two wedge blocks 24 abut against the bottom surface of the bottom plate 1, so that the wheel fixing mechanism remains in a locked state; when unlocking, it is only necessary to rotate the column 23, match the wedge blocks with the grooves 25, move the column 23 upward, and after passing through the through hole 22, the end faces of the bottom of the other two reverse wedge blocks abut against the top surface of the bottom plate, thereby preventing the wheel fixing mechanism from moving downward under the action of gravity, so that the wheel fixing mechanism is located above the wheel and maintains a stable state, thereby achieving the purpose of unlocking.

[0044] Furthermore, a "┓"-shaped channel 26 is provided through the bottom of the vertical plate 2, and the channels 26 at the bottom of the two vertical plates 2 are provided correspondingly. The two channels are located below the bottom plate, and the bottom opening of the channel 26 corresponds to the wheel, providing space for the connecting rod 21 to move up and down. The fixing groove 20 is provided at the bottom opening of the channel 26 and is located in the channel, and can move up and down in the channel. The connecting rod 21 passes through the channel 26 and extends out of the channel 26, that is, the connecting rod extends out of the horizontal part of the channel. The shape of the connecting rod can be adaptively changed according to the channel and the movement path of the wheel fixing mechanism, and can be rod-shaped or plate-shaped. In order to ensure the stability of the operation of the wheel fixing mechanism, a vertical rod 49 that passes through the connecting rod can be provided in the channel so that the connecting rod moves up and down along the vertical rod.

[0045] For further information, please refer to Figure 1 , Figure 7-Figure 10As shown, a slide plate 3 is slidably arranged between the vertical plates 2, and a measuring piece 4 is hinged at one end of the slide plate 3, and the measuring piece is in the shape of a plate. An angle disk 5 is arranged on the slide plate 3, and the center of the angle disk 5 is coaxial with the hinge of the slide plate 3 and the measuring piece 4. The angle disk is preferably a semicircular measuring ruler. When the measuring piece 4 rotates, the angle is directly indicated on the angle disk, and the reading is directly taken. A bottom plate fixing part for fixing the bottom plate 1 is arranged on the outer side of the vertical plate 2, and the bottom plate fixing part directly fixes the bottom plate to the wall, thereby avoiding the movement of the entire identification device, which leads to inaccurate measurement. A detection part is detachably arranged on the top of the vertical plate 2, and the flatness of the wall can be detected.

[0046] Furthermore, a strip notch 50 is provided on one side of the hinge between the slide plate 3 and the measuring member 4, a fixed shaft 51 is provided in the strip notch 50 along its length direction, and an arc groove which is interference fit with the fixed shaft 51 is provided on the bottom surface of the measuring member 4, so that the measuring member can rotate relative to the fixed shaft under the action of external force. The angle can be adjusted by rotating the measuring member 4. The angle disk 5 is sleeved and fixed on the fixed shaft 51, and one end thereof does not exceed the outside of the slide plate 3. According to actual conditions, the dials can be respectively provided on the fixed shaft and located at both ends of the measuring member. When the measuring member 4 is perpendicular to the slide plate 3, the outer side of the measuring member 4 is flush with the side of the slide plate 3 where the strip notch is provided, thereby ensuring the accuracy of the measured angle. At the same time, a center line is provided at both ends of the measuring member, coinciding with 90° of the dial.

[0047] Furthermore, in order to quickly read the angle, a pointer 52 can be fixed on the fixed shaft 51. The pointer is made of a transparent material, which is convenient for reading the dial. When the measuring piece 4 is perpendicular to the slide plate 3, the pointer 52 can coincide with the center line of the measuring piece. The pointer 52 is arranged adjacent to the dial 5 and is arranged outside the dial. When reading the degree, the pointer 52 only needs to be moved to coincide with the center line of the measuring piece to read the angle.

[0048] Furthermore, a slider 6 is symmetrically arranged on the corresponding plate surface of the vertical plate 2, and the slider is in a strip shape and arranged along the length direction of the vertical plate. Slide grooves adapted to the slider 6 are arranged on both sides of the slide plate 3, so that the slide plate 3 can reciprocate along the slider 6. The arrangement of the slider and the slide plate can make the edge of the slide plate fit the wall, avoiding a certain gap between the slide plate and the wall due to the arrangement of the bottom plate fixing parts, thereby preventing inaccurate measurement.

[0049] Furthermore, a fixing plate 7 corresponding to the vertical plate 2 is provided on the slide plate 3, the fixing plate and the vertical plate are parallel to each other, and a slide plate fixing member for fixing the slide plate 3 is provided on the fixing plate 7 and located above the slide plate 3, one end of the slide plate fixing member passes through the fixing plate 7 and abuts against the vertical plate 2. When the slide plate is moved to a suitable position, in order to prevent the slide plate from moving again along the slide block, the slide plate is fixed to the vertical plate by the slide plate fixing member, thereby ensuring the accuracy of the measurement.

[0050] Furthermore, the skateboard fixing part includes a sleeve 8 with an opening at one end, the open end of the sleeve is fixed to the fixing plate, and a positioning hole 29 communicating with the sleeve is provided on the fixing plate. A fixing column 9 is provided in the sleeve 8, and a spring 10 is provided outside the fixing column 9. One end of the spring 10 is fixed to the inner end surface of the sleeve 8, and the other end is abutted against a baffle 11 provided in the circumferential direction of the fixing column 9. The baffle can be an annular baffle or a cylindrical baffle column, which is mainly used to support the other end of the spring.

[0051] Furthermore, a clamping member 12 is provided on the side wall of the fixed column 9 away from the stopper 11, and the clamping member is preferably in a columnar shape. A sliding groove 13 is provided on the side wall of the sleeve 8 along its length direction (or the direction of the open end), and a limiting notch 14 is provided at one end of the sliding groove 13 away from the open end of the sleeve 8, which is adapted to the clamping member 12 and arranged along the circumference of the sleeve 8. The fixed column 9 extends into the sleeve 8, and the clamping member 12 passes through the sliding groove 13. By shifting the clamping member 12, the fixed column moves along the sliding groove, and the fixed column is rotated by the clamping member, so that the clamping member is clamped into the limiting notch. At this time, the spring is compressed, and the slide plate fixing member releases the fixing of the slide plate; when the fixed column is rotated and the clamping member is located in the area of ​​the sliding groove, the restriction on the fixed column is released, and under the action of the spring, the fixed column is driven to move toward the fixed plate, and passes through the positioning hole 29 to abut against the vertical plate 2, thereby fixing the slide plate.

[0052] Furthermore, the bottom plate fixing member includes a fixing tube 15 respectively arranged on the outside of the vertical plate 2 and arranged along the length direction thereof. The shape of the fixing tube is not limited. A fixing rod 16 with both ends extending out of the fixing tube 15 is arranged inside the fixing tube 15. One end of the fixing rod 16 extends out of the fixing tube and is hinged with a suction cup 17, and the other end is provided with a limiting plate 18. When the suction cup needs to be fixed to the wall, the limiting plates can be pushed respectively, so that the two suction cups are in contact with the wall and fixed by adsorption. The fixing method is flexible, and the use of the suction cup is not affected even if the wall surface is uneven.

[0053] Furthermore, in order to better adapt to different ground environments, when the wheels cannot fix the entire device, in order to make the fixing rod move toward the wall and fix the suction cup to the wall, each fixing cylinder 15 is vertically penetrated by an active adjustment mechanism and / or a driven adjustment mechanism that drives the fixing rod 16 to move axially along the fixing cylinder 15 and adjusts the height of the base plate 1. When only one active adjustment mechanism or driven adjustment structure is provided on each fixing cylinder, it is preferably provided in the middle position of the fixing cylinder 15. When multiple active adjustment mechanisms are provided, the setting positions can be set according to actual conditions. When an active adjustment mechanism and a driven adjustment mechanism are provided at the same time, it is preferred that an active adjustment mechanism and a driven adjustment mechanism are provided on the same fixing cylinder, and the active adjustment mechanisms on the two fixing cylinders are provided correspondingly. The setting conditions are as follows: Figure 1 shown.

[0054] Furthermore, the active adjustment mechanism includes an adjustment cylinder 31 that vertically penetrates the fixed cylinder 15 and is in clearance with the fixed cylinder 15. The screw 27 is connected to the inner thread of the adjustment cylinder 31. Both ends of the screw 27 extend out of the adjustment cylinder 31. The top of the screw and the top of the adjustment cylinder are circumferentially provided with a turntable for easy operation. The fixed rod 16 is provided with a guide groove 32 along its axial direction. A rack 33 is provided in the guide groove 32. The part of the adjustment cylinder 31 located in the fixed cylinder 15 is sleeved and fixed with a gear 34 that meshes with the rack 33. By rotating the adjustment cylinder, the fixed rod 16 is driven to reciprocate along the fixed cylinder 15 with the cooperation of the gear and the rack, and the length of the guide groove 32 or the rack determines the length that the fixed rod can move. It should be noted that the setting of the active adjustment mechanism can fix the fixed cylinder and the fixed rod to a certain extent. Combined with the fixation of the wheel, the stability of the entire device is better. At the same time, the screw rod 27 is rotated to move its bottom end toward the bottom surface, and a cone head 53 is provided at the bottom end of the screw rod 27 and the bottom end of the adjusting rod 36, so that the screw rod and the adjusting rod can be better fixed.

[0055] It should be noted that: although the suction cup can be fixed to the wall by directly pushing the fixing rod, the wheels are of limited use when the ground is uneven, and the bottom plate may need to be raised for fixing. At this time, active adjustment mechanism and passive adjustment mechanism are needed. The adjustment of these two mechanisms can be operated according to the actual situation, such as adjusting the height first and then fixing it to the wall, or fixing it to the wall first and then adjusting the height. The setting of the adjustment mechanism is mainly to make the whole device adapt to different or more complex ground conditions.

[0056] Furthermore, the driven adjustment mechanism can assist the lifting of the base plate 1. The driven adjustment mechanism includes a threaded tube 35 that vertically penetrates the fixed tube 15 and is fixed thereto. The threaded tube 35 is internally threaded with an adjustment rod 36. The fixed rod 16 is provided with a movable groove 37 in the same direction as the guide groove 32. The adjustment rod has the same function as the screw rod. The movable groove has the same size and direction as the guide groove. The position of the adjustment rod relative to the movable groove is the same as the position of the screw rod relative to the guide groove. The active adjustment mechanism and the driven adjustment mechanism can be set to adapt to more complex ground environments. When the ground is uneven, the stability of the entire device can be achieved by adjusting the active adjustment mechanism and the driven adjustment mechanism. At the same time, the inclination angle of the base plate can be flexibly adjusted.

[0057] For further reference, Figure 13-15In order to measure the wall in many aspects, at least one positioning cylinder 38 with a top opening is vertically arranged on the plate surface of the measuring piece 4, and the detection piece is detachably fixed by the positioning cylinder. The detection piece includes a connecting plate 39, and a screw rod 40 is rotatably connected to the connecting plate 39. Specifically, a notch is arranged on the top surface of the connecting plate 39, and the screw rod is rotatably arranged in the notch and fixed to the two side walls of the notch by bearings. A nut 41 is fixedly arranged on the screw rod 40, and a displacement sensor 42 is arranged on the nut 41. A motor 43 is arranged at one end of the screw rod 40. A positioning rod 44 inserted into the positioning cylinder 38 is arranged at the bottom of the connecting plate 39, and a telescopic rod 45 for driving the connecting plate 39 to rise and fall is arranged on the plate surface of the measuring piece 4. It should be noted that the telescopic rod is arranged separately from the connecting plate, and the thickness of the connecting plate 39 is greater than the thickness of the measuring piece 4, so that the output end of the telescopic rod can contact the bottom end of the connecting plate when it is extended and retracted, thereby lifting the connecting plate. The height to which the connecting plate can be lifted is determined by the length of the positioning rod 44. During measurement, the motor is started to drive the displacement sensor to move along the lead screw, thereby measuring and obtaining corresponding data.

[0058] Specifically: the displacement sensor 42 is connected to the single-chip microcomputer acquisition system through a wire, and the displacement change of the displacement sensor is collected and analyzed by the single-chip microcomputer acquisition system to analyze the flatness of the wall. The displacement sensor moves horizontally and vertically under the action of the screw rod and the telescopic rod. Under the joint action of the two, the displacement sensor moves in a two-dimensional plane within the square frame along with the nut. A ball is installed at the front end of the floating displacement scale of the displacement sensor to adjust the distance from the device to the wall. The ball at the front end of the floating displacement scale is pressed against the wall, and its internal spring makes the ball always roll against the wall. When the displacement sensor is started, the measuring part is vertical relative to the base plate and can be set according to actual conditions. At this time, the distance between the base plate and the wall can be adjusted by rotating the adjustment cylinder 31, thereby realizing the adjustment of the distance between the displacement sensor and the wall.

[0059] When the wall surface becomes uneven, the floating displacement ruler will continue to float under the action of the compression spring inside the displacement sensor, ensuring that the ball at the front end always rolls against the wall surface. The displacement sensor transmits the floating displacement ruler floating change displacement signal to the single-chip microcomputer acquisition system, and analyzes the displacement floating change value to determine the flatness of the wall surface.

[0060] Furthermore, in order to meet the higher height requirements of the measuring piece, a heightening piece can be detachably provided on the top of the measuring piece 4, and the heightening piece includes a heightening plate 46, the thickness of which is preferably the same as that of the connecting plate, and a connecting column 47 adapted to the positioning cylinder 38 is provided at the bottom of the heightening plate 46, and a connecting cylinder 48 corresponding to the position of the positioning cylinder 38 is provided on the plate surface of the heightening plate 46. At the same time, the detection piece can be fixed on the heightening plate in the same way. At this time, the telescopic piece can be provided on the measuring piece, but there are requirements for its stroke; or it can also be provided on the heightening plate, and a groove 54 running through the top of the heightening plate 46 is provided at the position of the middle plate surface, and the telescopic rod is provided in the groove, so that the output end of the telescopic rod can be against the bottom surface of the connecting plate 39 during movement, thereby driving the connecting plate to rise. Of course, multiple heightening pieces can be connected in sequence above the heightening piece to meet different height requirements.

[0061] Furthermore, a level 28 is provided on the outer side of the bottom plate 1 and on both side walls of the fixing tube 15, respectively, so as to observe the horizontal state of the bottom plate and adjust it through the active adjustment mechanism and / or the passive adjustment mechanism as needed.

[0062] When using the present invention, it is only necessary to move the entire device to one side of the wall, push the limit plate, make the suction cup suck the wall, so that the bottom plate and the wall are in a relatively fixed state, and then operate the wheel fixing mechanism to lock the wheels. At this time, the inclination of the bottom surface can be recorded by observing the level meter. Then, push the skateboard to make it against the wall, operate the skateboard fixing part, fix the skateboard to prevent it from moving, and do not hold the skateboard with your hands; then read the angle of the wall inclination by measuring the inclination of the measuring part and the corresponding angle disk. At the same time, according to the on-site measurement situation, the active adjustment mechanism and the driven adjustment mechanism can be adjusted to adjust the height of the bottom plate and fix it to the ground.

[0063] Then the motor and telescopic rod are started, and the flatness of the wall is measured by the displacement sensor. If there is a requirement, it can be adjusted by adding at least one height-increasing piece.
