Description

Technical Field

[0001] The invention relates to the technical field of building construction measurement, and in particular to a prefabricated assembled building construction measurement device. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories are pre-processed and manufactured, then transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] During the construction of vertical wall panels in prefabricated buildings, the lifting machinery will lift the vertical wall panels to the foundation connection foundation, and then connect the wall panels and the foundation at both ends of the diagonal support to ensure that the wall panels are stably placed. During this process, it is necessary to use a level ruler, laser level or other measuring equipment to detect the verticality of the wall panels, and adjust the length of the diagonal support to ensure that the wall panels are placed vertically, thereby ensuring the installation accuracy. However, when actually adjusting the vertical wall panels vertically, it is impossible to manually calculate the number of rotations of the diagonal support based on the inclination angle of the wall panels. Therefore, the diagonal support needs to be rotated and adjusted multiple times. In the gap between each adjustment, the verticality of the wall panels needs to be measured again according to the level ruler or laser level. After multiple verticality measurements and rotation of the diagonal support, the wall panels can finally be placed vertically. As a result, the installation process of the vertical wall panels is more cumbersome, thereby reducing the installation efficiency. Summary of the invention

[0004] In view of the problem in the prior art that multiple step-by-step operations are required when adjusting the verticality of vertical wall panels, which reduces the installation efficiency, a prefabricated and assembled building construction measurement device is proposed.

[0005] The purpose is that the detection module can fit the wall panel and display the angle in real time through the display module, so that the oblique support can quickly drive the wall panel to be placed vertically.

[0006] The technical solution of the present invention is a prefabricated and assembled construction measurement device, comprising a boom and a measurement mechanism installed on the boom, wherein the measurement mechanism comprises a detection module and a display module, and the detection module and the display module are connected by an angle magnification component;

[0007] The detection module comprises two detection arms rotatably connected to the suspension arm, the detection arms are in a U-shaped structure, and both ends of the detection arms are rotatably connected to detection wheels;

[0008] The display module comprises an indicator plate rotatably connected to the boom, a fixing plate is fixedly connected to the lower end of the indicator plate, a counterweight is fixedly connected to the lower end of the fixing plate, and scale plates are rotatably connected to both sides of the indicator plate;

[0009] The angle magnification component includes gear sets arranged on both sides of the fixed plate. The gear sets are in driving connection with the dial, and an arc-shaped rack is meshed and connected to the gear sets. The arc-shaped rack is fixedly connected to the detection arm.

[0010] With the above technical solution, the upper end of the boom is suspended on the inclined support hinge of the wall panel. Driven by the gravity of the counterweight, the detection wheel is brought into contact with the wall panel, and the detection arm is parallel to the wall panel. Since the fixed plate is always vertically placed, when the detection arm is in a non-vertical state, the gear set is driven to rotate by the arc-shaped rack, and the gear set drives the dial to rotate. Under the action of the gear set, the inclination angle of the detection arm can be magnified proportionally to the dial, enabling the staff to more intuitively view the inclination data of the wall panel.

[0011] Further, the boom includes a hanging rod. One end of the hanging rod is fixedly connected with a U-shaped boom. The lower end of the boom is fixedly connected with a rotating shaft. Both the detection arm and the indicating disk are rotatably connected to the rotating shaft.

[0012] With the above technical solution, the upper end of the hanging rod is hook-shaped and can be hung on the inclined support hinge of the wall panel. Both the detection arm and the indicating disk can rotate freely on the rotating shaft. The counterweight drives the indicating disk to rotate under the action of gravity, and at the same time, the counterweight drives the detection wheel to contact one side of the wall panel.

[0013] Further, angle scales are engraved on the sides of the two dials away from each other. An indicating arrow is provided on one side of the angle scale. The indicating arrow is fixedly connected to the indicating disk.

[0014] With the above technical solution, the indicating arrow is set at the three o'clock position of the indicating disk. The angle scale is at the zero scale line at the three o'clock position and increases in angle on both sides. When the wall panel is in an inclined state, the angle scale can magnify the inclination angle of the wall panel by an integer multiple. Through the deviation between the indicating arrow and the zero scale line, the inclination data of the wall panel can be more intuitively displayed.

[0015] Further, the gear set includes a first gear. The first gear is meshed and connected with the arc-shaped rack. A second gear is meshed on one side of the first gear. A third gear is coaxially and fixedly connected to one side of the second gear. A gear ring is meshed on the third gear. The gear ring is coaxially connected and fixed to the dial.

[0016] Both the first gear and the second gear are rotatably connected to the fixed plate, and the diameter of the second gear is smaller than the diameters of the first gear and the third gear.

[0017] By adopting the above technical solution, when the detection wheel is in contact with the wall panel, the detection arm is parallel to the wall panel, and the angle between the detection arm and the fixed plate is the inclination angle of the wall panel. When the detection arm rotates, it drives gear one through the arc-shaped rack, gear one drives gear two, and then gear three drives the dial connected to the gear ring to rotate, so that the inclination angle of the wall panel can be magnified by an integer multiple.

[0018] Furthermore, an arc-shaped hole is provided on the indicating plate, a limiting rod is provided in the arc-shaped hole, and an end of the limiting rod is connected and fixed to the detection arm.

[0019] By adopting the above technical solution, the arc center of the arc hole is located on the axis of the rotating shaft, and the limit rod is arranged in the arc hole to limit the rotation angle of the detection arm, thereby preventing the arc rack from being disengaged from the meshing with the gear one.

[0020] Furthermore, a feedback mechanism is installed on the display module, and the feedback mechanism includes a connecting seat arranged on the indicator disk, an elastic plate with an L-shaped structure is connected in the connecting seat, and striking blocks are fixedly connected to both sides of the elastic plate, and a sounding plate fixedly connected to the indicator disk is provided on one side of the striking block;

[0021] The feedback mechanism also includes a plurality of shifting blocks arranged in a ring shape with equal intervals, and the shifting blocks are fixedly connected to a corresponding one of the scale plates.

[0022] By adopting the above technical scheme, the length of the arc formed by multiple shift blocks is the same as the arc length of the angle scale. When the zero scale line of the dial approaches the indicator arrow, the elastic plate bends and accumulates force when the shift block contacts the elastic plate. When the elastic plate bends to a certain extent, its end does not contact the current shift block and rebounds, driving the striking block to hit the sound plate, emitting sound vibration. In this way, every time the dial rotates a certain angle, the sound plate emits a sound vibration reminder, which can be used to remind the staff of the adjustment distance of the current wall panel, thereby ensuring the synchronous adjustment of multiple inclined supports.

[0023] Furthermore, a slide groove 1 is provided in the connection seat, a fixed block is fixedly connected to one end of the elastic plate, the fixed block is arranged in the slide groove 1, a connecting plate is provided on the lower side of the fixed block, and the connecting plate is elastically connected to the indicator plate through a spring 1;

[0024] The two shifting blocks close to the elastic plate are in a right-angle trapezoidal structure.

[0025] With the above technical solution, when the zero scale line of the angle scale approaches the indicating arrow, the inclined surface of the slider near the elastic plate contacts the elastic plate. While the elastic plate bends and stores energy, the whole moves downward along the chute through the fixed block, driving the first spring to compress. After the slider cancels the contact with the elastic plate, the elastic plate swings to drive the striker to strike the sounding plate. At the same time, the reset of the first spring drives the elastic plate to move. Since the two sounding plates are arranged in a V shape, the elastic plate can still drive the striker to contact the sounding plate when the swing amplitude decreases, thus prolonging the reminder duration of the vibration sound. The sound duration generated when the slider contacts the elastic plate is longer than that generated when the other sliders contact the elastic plate. The reminder of the longer sound duration enables the staff to know that the indicating arrow points to the zero scale line of the angle scale at this time, so as to determine that the wall panel is vertically placed.

[0026] Further, chute two is provided on both symmetric sides of chute one. Guide blocks are fixedly connected to both symmetric sides of the fixed block. The guide blocks are slidably connected in chute two. Braking inclined surfaces are provided at the corners of the fixed block. The braking inclined surfaces are in abutting cooperation with chute one.

[0027] With the above technical solution, there is a certain gap between chute one and the fixed block. When the first spring drives the elastic plate to rise during reset, the elastic plate swings by itself and drives the fixed block to rotate. When the braking inclined surface abuts against chute one, the friction force during the rise of the fixed block is increased, so that the elastic plate stops rising while swinging at this time. When the braking inclined surface does not abut against chute one, the first spring continues to drive the elastic plate to rise, thereby prolonging the rising duration of the elastic plate and further increasing the sounding duration of the striker striking the sounding plate.

[0028] Further, a braking component is installed on the indicating disk. The braking component includes a rectangular frame slidably connected to the indicating disk. One side of the rectangular frame is elastically connected to the indicating disk through the second spring. And two clamping plates are fixedly connected to the rectangular frame. The clamping plates are in clamping cooperation with the notches provided on the scale disk.

[0029] The rectangular frame is fixedly connected to the connecting seat. And the connecting seat is slidably connected to the indicating disk.

[0030] With the above technical solution, a through hole is provided on the indicating disk below the empty slot. The rectangular frame is slidably arranged in the through hole. The elastic force of the second spring is greater than that of the first spring. When no external force acts, the second spring drives the rectangular frame to abut against the upper part of the through hole and drives the clamping plates to be in clamping connection with the notches, which can limit the rotation of the scale disk and avoid the precision error caused by shaking when not in use. Pulling the rectangular frame downward can drive the clamping plates to cancel the clamping connection with the notches. At this time, the scale disk can rotate according to the inclination of the detection arm.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. After being hung on the inclined support hinge seat of the wall panel through the jib, under the action of the gravity of the counterweight block, the fixing plate is driven to be vertically placed, and the detection wheel is brought into contact with one side of the wall panel. When the detection arm deflects relative to the fixing plate, the angle amplification component can drive the dial to rotate, magnifying the inclination angle of the wall panel by an integer multiple through the dial, which is convenient for the staff to view more intuitively. At the same time, the wall panel is measured in real time, thus saving the intermittent measurement of the wall panel by the staff, simplifying the installation steps, and improving the installation efficiency.

[0033] 2. When the dial rotates by a certain angle, the elastic plate is driven to bend and store energy through the dial block. The elastic plate drives the striker to strike the sounding plate to generate a vibrating sound for reminding, so as to remind the staff. According to this feedback reminder, multiple inclined supports can be synchronously adjusted, improving the installation standard of the wall panel. When the trapezoid-shaped dial block contacts the elastic plate, it can drive the elastic plate to move, increasing the duration of the striker hitting the sounding plate, so as to be used to improve the staff's perception that the wall panel is vertically placed at this time.

[0034] 3. During the movement and swinging of the elastic plate, the braking inclined plane of the fixed block intermittently abuts against the first chute, which can temporarily stop the movement of the elastic plate, further extend the movement time of the elastic plate, and thus synchronously extend the vibrating sound reminder. Furthermore, the sound reminder time when the wall panel is vertically placed is extended, which is beneficial for the staff to distinguish the lengths of the sound reminders of the wall panel in different inclined states.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] Example 1, reference Figures 1 - 6 , which is the first embodiment of the present invention, provides a prefabricated and assembled construction measurement device, including a boom 1, and also includes a measurement mechanism installed on the boom 1, the measurement mechanism includes a detection module 2 and a display module 3, and the detection module 2 and the display module 3 are connected by an angle magnification component 4; the detection module 2 includes two detection arms 21 rotatably connected to the boom 1, the detection arms 21 are U-shaped, and both ends of the detection arms 21 are rotatably connected to detection wheels 22; the display module 3 includes an indicator plate 31 rotatably connected to the boom 1, the lower end of the indicator plate 31 is fixedly connected to a fixed plate 32, the lower end of the fixed plate 32 is fixedly connected to a counterweight block 33, and both sides of the indicator plate 31 are rotatably connected to a dial 34; the angle magnification component 4 includes a gear set 41 arranged on both sides of the fixed plate 32, the gear set 41 is connected by transmission to the dial 34, and the gear set 41 is meshed with an arc rack 42, and the arc rack 42 is fixedly connected to the detection arm 21.

[0049] Specifically, the upper end of the boom 1 is suspended on the inclined support hinge seat of the wall panel. Under the action of the gravity of the counterweight 33, the detection wheel 22 is driven to fit with the wall panel, and the detection arm 21 is parallel to the wall panel. Since the fixed plate 32 is always vertically placed, when the detection arm 21 is in a non-vertical state, the arc-shaped rack 42 drives the gear set 41 to rotate, and the gear set 41 drives the dial 34 to rotate. Under the action of the gear set 41, the inclination angle of the detection arm 21 can be amplified in equal proportion on the dial 34, enabling the staff to more intuitively view the inclination data of the wall panel.

[0050] Referring to Figures 2 - 4 , the boom 1 includes a hanging rod 11. One end of the hanging rod 11 is fixedly connected with a hanging rod 12 in a U-shaped structure. The lower end of the hanging rod 12 is fixedly connected with a rotating shaft 13. The detection arm 21 and the indicating disc 31 are both rotatably connected to the rotating shaft 13.

[0051] Specifically, the upper end of the hanging rod 11 is in a hook shape and can be hung on the inclined support hinge seat of the wall panel. The detection arm 21 and the indicating disc 31 can freely rotate on the rotating shaft 13. Under the action of gravity, the counterweight 33 drives the indicating disc 31 to rotate, and at the same time, the counterweight 33 drives the detection wheel 22 to contact one side of the wall panel.

[0052] Among them, the distance from the detection wheel 22 to the axis of the rotating shaft 13 is greater than the distance from the edge of the indicating disc 31 to the axis of the rotating shaft 13. Since the upper end of the hanging rod 11 is close to the wall panel, the hanging rod 11, the hanging rod 12 and the wall panel are arranged at an acute angle. When the wall panel tilts to either side, under the action of the gravity of the counterweight 33, the detection wheel 22 can be driven to keep in contact with the wall panel.

[0053] Referring to Figure 4 , angle scales 35 are engraved on the sides of the two dials 34 that are away from each other. An indicating arrow 36 is provided on one side of the angle scale 35. The indicating arrow 36 is fixedly connected to the indicating disc 31.

[0054] Specifically, the indicating arrow 36 is set at the three o'clock position of the indicating disc 31. The angle scale 35 is at the zero scale line at the three o'clock position and increases in angle on both sides. When the wall panel is in an inclined state, the angle scale 35 can amplify the inclination angle of the wall panel in integer multiples. Through the deviation between the indicating arrow 36 and the zero scale line, the inclination data of the wall panel can be more intuitively displayed.

[0055] Referring to Figure 3 , Figure 5, the gear set 41 includes a first gear 411, the first gear 411 is meshed and connected with the arc-shaped rack 42, a second gear 412 is meshed and connected to one side of the first gear 411, a third gear 413 is coaxially and fixedly connected to one side of the second gear 412, a gear ring 43 is meshed with the third gear 413, and the gear ring 43 is coaxially and fixedly connected with the dial 34; both the first gear 411 and the second gear 412 are rotatably connected to the fixed plate 32, and the diameter of the second gear 412 is smaller than the diameters of the first gear 411 and the third gear 413.

[0056] Specifically, when the detection wheel 22 is in contact with the wall panel, the detection arm 21 is parallel to the wall panel. The included angle between the detection arm 21 and the fixed plate 32 is the inclination angle of the wall panel. When the detection arm 21 rotates, it drives the first gear 411 through the arc-shaped rack 42, the first gear 411 drives the second gear 412, and then drives the dial 34 connected to the gear ring 43 to rotate through the third gear 413, so that the inclination angle of the wall panel can be amplified by an integer multiple.

[0057] It can be understood that by using the setting of the gear set 41, the inclination angle of the wall panel can be amplified by an integer multiple through the dial 34. In this technical solution, by setting the diameter ratio of the first gear 411, the second gear 412, and the third gear 413, the inclination angle of the wall panel can be amplified by 10 times. That is, when the inclination angle of the wall panel is 1°, the included angle between the angle scale 35 and the indicating arrow 36 is 10°. It can also be amplified to other integer multiples according to the actual situation.

[0058] Refer to Figure 5 , Figure 6 , an arc-shaped hole 37 is formed on the indicating disk 31, and a limiting rod 5 is arranged in the arc-shaped hole 37. The end of the limiting rod 5 is fixedly connected to the detection arm 21.

[0059] Specifically, the center of the radian of the arc-shaped hole 37 is located on the axis of the rotating shaft 13. The limiting rod 5 arranged in the arc-shaped hole 37 can limit the rotation angle of the detection arm 21, thereby preventing the arc-shaped rack 42 from disengaging from the engagement with the first gear 411.

[0060] Embodiment 2, refer to Figures 7 - 9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a feedback mechanism 6 is installed on the display module 3. The feedback mechanism 6 includes a connection seat 61 arranged on the indicating disk 31. An L-shaped elastic plate 62 is connected in the connection seat 61. Impact blocks 63 are fixedly connected to both sides of the elastic plate 62. A sounding plate 64 fixedly connected to the indicating disk 31 is arranged on one side of the impact block 63; the feedback mechanism 6 further includes a plurality of dial blocks 65 arranged at equal intervals in a ring shape. The dial blocks 65 are fixedly connected to one of the corresponding dials 34.

[0061] Specifically, the arc lengths formed by multiple shifting blocks 65 are the same as the arc length of the angle scale 35. When the zero scale line of the dial 34 approaches the indicating arrow 36, the elastic plate 62 bends and stores energy when the shifting block 65 contacts the elastic plate 62. When the elastic plate 62 bends to a certain extent, its end no longer contacts the current shifting block 65 and rebounds, driving the striking block 63 to strike the sounding plate 64, generating a sound vibration. Thus, when the dial 34 rotates by a certain angle, the sounding plate 64 generates a sound vibration reminder, which can be used to remind the staff of the adjustment distance of the current wall panel, thereby ensuring synchronous adjustment of multiple inclined supports.

[0062] Among them, a convex-shaped empty groove is formed at the twelve o'clock position of the indicating disk 31. The connecting seat 61 is arranged at the lower part of the empty groove, and the sounding plate 64 is arranged at the upper part of the empty groove, and the two sounding plates 64 are arranged in a V-shaped structure.

[0063] Refer to Figures 8 - 9 As shown in the figure, a first chute 611 is formed inside the connecting seat 61. One end of the elastic plate 62 is fixedly connected with a fixing block 66. The fixing block 66 is arranged inside the first chute 611. A connecting plate 67 is arranged below the fixing block 66. The connecting plate 67 is elastically connected with the indicating disk 31 through a first spring 68; the two shifting blocks 65 close to the elastic plate 62 are in a right trapezoidal structure.

[0064] Specifically, when the zero scale line of the angle scale 35 approaches the indicating arrow 36, the inclined surface of the shifting block 65 close to the elastic plate 62 contacts the elastic plate 62. While the elastic plate 62 bends and stores energy, the whole moves downward along the first chute 611 through the fixing block 66, driving the first spring 68 to be compressed. After the shifting block 65 cancels the contact with the elastic plate 62, the elastic plate 62 swings to drive the striking block 63 to strike the sounding plate 64, and at the same time, the first spring 68 resets to drive the elastic plate 62 to move. Since the two sounding plates 64 are arranged in a V shape, the elastic plate 62 can still drive the striking block 63 to contact the sounding plate 64 when the swinging amplitude decreases, thereby prolonging the reminder duration of the vibration sound. The sound duration generated when the shifting block 65 contacts the elastic plate 62 is longer than the sound duration generated when the other shifting blocks 65 contact the elastic plate 62. The longer-duration sound reminder can enable the staff to know that the indicating arrow 36 points to the zero scale line of the angle scale 35 at this time, so as to determine that the wall panel is vertically placed.

[0065] Refer to Figures 8 - 9 As shown in the figure, second chutes 612 are formed on both sides symmetric to the first chute 611. Guide blocks 69 are fixedly connected to both sides symmetric to the fixing block 66. The guide blocks 69 are slidably connected inside the second chutes 612. Braking inclined surfaces 661 are formed at the corners of the fixing block 66. The braking inclined surfaces 661 are in abutting cooperation with the first chute 611.

[0066] Specifically, there is a certain gap between the slide groove 1 611 and the fixed block 66. When the spring 1 68 is reset and drives the elastic plate 62 to rise, the elastic plate 62 itself deflects and drives the fixed block 66 to rotate. When the braking slope 661 abuts against the slide groove 1 611, the friction force of the fixed block 66 when it rises is increased, so that the elastic plate 62 stops rising while swinging. When the braking slope 661 does not abut against the slide groove 1 611, the spring 1 68 continues to drive the elastic plate 62 to rise, thereby extending the rising time of the elastic plate 62, thereby further increasing the pronunciation time of the striking block 63 striking the pronunciation plate 64. The rest of the structure is the same as that of the first embodiment.

[0067] Example 3, reference Figure 7 , Figure 8 , Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a brake assembly 7 is installed on the indicator disk 31, and the brake assembly 7 includes a rectangular frame 71 slidably connected to the indicator disk 31. One side of the rectangular frame 71 is elastically connected to the indicator disk 31 through a spring 2 72, and two clamping plates 73 are fixedly connected to the rectangular frame 71, and the clamping plates 73 are snap-fitted with the notches provided on the dial 34; the rectangular frame 71 is fixedly connected to the connecting seat 61, and the connecting seat 61 is slidably connected to the indicator disk 31.

[0068] Specifically, the indicator plate 31 is provided with a through hole at the lower side of the empty slot, and the rectangular frame 71 is slidably arranged in the through hole. The elastic force of the second spring 72 is greater than the elastic force of the first spring 68. When no external force is applied, the second spring 72 drives the rectangular frame 71 to abut against the upper part of the through hole, and drives the clamping plate 73 to clamp with the notch, which can limit the rotation of the scale plate 34 to avoid shaking when not in use and causing precision errors. Pulling the rectangular frame 71 downward can drive the clamping plate 73 to cancel the clamping with the notch, and the scale plate 34 can rotate according to the inclination of the detection arm 21. The rest of the structure is the same as that of the second embodiment.

[0069] Among them, when the card plate 73 is not in contact with the dial 34, the height of the upper end of the elastic plate 62 is lower than the height of the bottom surface of the shift block 65, so that the dial 34 can rotate quickly according to the tilt state of the detection arm 21. When the spring 2 72 drives the card plate 73 to contact the inner circle of the dial 34, the height of the upper end of the elastic plate 62 is higher than the height of the bottom surface of the shift block 65. When the dial 34 rotates in the opposite direction, the shift block 65 can drive the elastic plate 62 to bend and accumulate force.

[0070] Among them, the detection arm 21 and the suspension rod 12 are both provided with operation holes at the positions of the brake assembly 7, and the rectangular frame 71 can be moved by the fingers of the staff through the operation holes.

[0071] Based on Examples 1-3, the working principle of the present invention is as follows: after the vertical wall panel is connected to the foundation, the two ends of the oblique support are respectively connected to the wall panel and the foundation, and the upper end of the hanging rod 11 is hung with the oblique support hinge on the wall panel. The staff drives the rectangular frame 71 to move downward so that the clamping plate 73 cancels the clamping connection with the notch. At this time, under the action of the gravity of the counterweight block 33, the fixed plate 32 is placed vertically, and the detection wheel 22 is fitted with the wall panel. The detection arm 21 is arranged parallel to the wall panel, so that when an angle deviation occurs between the detection arm 21 and the fixed plate 32, the arc-shaped rack 42 drives the gear set 41 to rotate, and the gear set 41 drives the dial 34 connected to the gear ring 43 to rotate. When the gear set 41 is set to descend, the inclination angle of the wall panel is magnified by an integer multiple through the dial 34, and the staff can vertically adjust the length of the oblique support according to the magnified angle.

[0072] During the process of adjusting the length of the inclined support, every time the dial 34 rotates a certain angle, the elastic plate 62 is driven by the shift block 65 to bend and accumulate force. After the shift block 65 is no longer in contact with the elastic plate 62, the elastic plate 62 swings to drive the striking block 63 to hit the sound plate 64. The vibration sound generated can help the staff to adjust multiple inclined supports synchronously.
