Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a positioning monitoring device for prefabricated buildings. Background Art

[0002] With the acceleration of the pace of life in my country and the advancement of related technologies, the application of prefabricated buildings is becoming more and more extensive. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings have short construction periods, are green and environmentally friendly, and have low costs, which are in line with the development trend of contemporary society. However, in the current prefabricated building forming process, there is no positioning monitoring device during the installation of the bottom template. The positioning of the bottom template and the foundation is basically based on manual groping or mirror reflection. The alignment process of the steel bars on the foundation and the steel bar holes on the bottom template requires two workers to operate at the same time. The operation process is that two workers hold the bottom template lifted by the tower crane and slowly move the bottom template by feeling to match the steel bar holes on the bottom template with the steel bars on the foundation. Alternatively, when positioning, a third worker bends down and takes a small mirror to observe whether the steel bar holes on the bottom template and the steel bars on the foundation correspond.

[0003] Traditional positioning monitoring methods, no matter which method they are, are too primitive and require two or more workers to participate in the operation. They are inefficient and consume a lot of manpower and material resources. In addition, the implementation method is not convenient enough and cannot be quick and easy.

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] refer to Figures 1 to 8 , an assembled building positioning monitoring device, comprising:

[0035] The load-bearing trolley 1 is located at the bottom of the entire device, and the load-bearing trolley 1 plays a supporting role and provides displacement;

[0036] A lifting assembly 6 is arranged at the upper end of the carrying trolley 1;

[0037] The translation assembly 12 is connected to the lifting assembly 6. The translation assembly 12 includes a moving mechanism 13 and two reinforcement mechanisms 24. The moving mechanism 13 is connected to the lifting assembly 6. The moving mechanism 13 includes four translation slides 21. The translation slides 21 are grouped in pairs. Both ends of a reinforcement mechanism 24 are fixedly connected to the two translation slides 21 in each group.

[0038] The positioning monitoring assembly 30 includes an infrared laser instrument 33, a positioning mechanism 39 and an alarm 48. The infrared laser instrument 33 is fixedly mounted on one end of the translation slide 21, the positioning mechanism 39 is fixedly mounted on the other end of the translation slide 21, and the alarm 48 is fixedly mounted on the upper end of the carrying trolley 1.

[0039] The load-bearing trolley 1 comprises a support platform 2, a support sleeve 3 and a support top plate 5, which are arranged in sequence from bottom to top above the load-bearing trolley 1, wherein the support platform 2 is horizontally fixedly connected to the body of the load-bearing trolley 1, the support sleeve 3 is vertically fixedly installed on the support platform 2, a side of the tube wall of the support sleeve 3 is formed with an avoidance through hole 4, and the support top plate 5 is horizontally fixedly installed on the upper end of the support sleeve 3. When the device is working, the load-bearing trolley 1 can move freely on the construction site. Since the load-bearing trolley 1 is overall low, it is convenient to install and position the bottom templates of different sizes. Other equipment can be installed on the support platform 2 of the trolley. The support sleeve 3 is used to install the lifting assembly 6. The avoidance through hole 4 facilitates the lifting assembly 6 to drive the translation assembly 12 and the positioning monitoring assembly 30 to move up and down. The support top plate 5 is fixedly installed on the top of the support sleeve 3. The support top plate 5 is used to limit the upper end of the lifting assembly 6, and the support top plate 5 also supports the lifting assembly 6.

[0040] The lifting assembly 6 includes a motor 7, a screw rod 9, a lifting slider 10, a base 11 and two limit rods 8. The output end of the motor 7 is fixedly installed downward above the support top plate 5. The base 11 is fixedly installed on the support platform 2 and is located inside the support sleeve 3. The screw rod 9 is arranged in a vertical state. One end of the screw rod 9 is movably connected to the base 11, and the other end is fixedly connected to the output end of the motor 7 through a coupling. The two limit rods 8 are symmetrically fixedly installed on both sides of the avoidance through hole 4. The lifting slider 10 is threadedly connected to the outside of the screw rod 9, and the two ends of the lifting slider 10 are against the two limit rods 8. When the device is working, the motor 7 is fixedly installed on the upper side of the supporting top plate 5 through the motor 7 frame, and the motor 7 drives the screw rod 9 to rotate. The screw rod 9 rotates in the lifting slider 10 to drive the lifting slider 10 to move in the vertical direction. The lifting slider 10 is limited by the limit rods 8 on both sides during the lifting process. The limit rods 8 ensure that the lifting slider 10 will not move during the movement, thereby improving the stability of the device. The movable shaft at the lower end of the screw rod 9 is connected to the base 11, and the base 11 ensures that the screw rod 9 will not separate from the device when it rotates.

[0041] The moving mechanism 13 also includes a support rod 14, two support arms 16, four sliding support frames 18, four pulleys 19 and two slide rails 20. The support rod 14 is arranged in a horizontal state, the support rod 14 is connected to the lifting slider 10, and extension arms 15 are formed at both ends of the support rod 14. The two support arms 16 are respectively fixedly connected to the extension arms 15 at both ends of the support rod 14, and a movable slide groove 17 is formed on the support arm 16. The two slide rails 20 are arranged in a horizontal state and parallel to the support rod 14. The lower end of the sliding support frame 18 is fixedly connected to the end of the slide rail 20, and the upper end is slidably connected to the support arm 16. The pulley 19 is arranged in the sliding support frame 18, and the pulley 19 wheel rim matches the movable slide groove 17, and the translation slide 21 is slidably connected to the slide rail 20. The up and down movement of the lifting slider 10 can drive the support rod 14 to move up and down. Therefore, when the lifting slider 10 determines the position, the position of the support rod 14 is also determined. At this time, the two support arms 16 are fixedly installed on the extension arms 15 at both ends of the support rod 14. The distance between the two support arms 16 is greater than the distance between the steel bars on the foundation of the prefabricated building. Therefore, the two support arms 16 can include at least four steel bars. When the device is working, since the production specifications and standards of the same batch of prefabricated buildings must be the same, that is, the relative positions of the steel bars formed on the prefabricated buildings produced in this batch are the same, the specific position parameters of the pulley 19 and the slide rail 20 in this device can be adjusted in advance. The pre-adjusted device can be repeatedly applied to multiple prefabricated buildings when positioning and monitoring the steel bars and steel bar holes. Compared with the special drive The positioning monitoring device that automatically adjusts the driving component and the automatic identification and positioning component has three significant advantages: first, the device only needs to be pre-adjusted before use, and after the pre-adjustment, there is no need to readjust the position parameters every time positioning monitoring is performed, so the work efficiency is higher; second, the device has no special driving components and automatic identification and positioning components, and there is no software coding for automatic identification and positioning, so the manufacturing and processing costs of the device are lower, which is conducive to large-scale production in the market later and improves economic benefits. In addition, since the device does not have those complex mechanisms, the trolley has a smaller load-bearing capacity and improves the endurance of the trolley; third, the device has a simple structural design and is easy for workers to operate, so there is no need for excessive training for workers, and because of the simple structure, it is easier to inspect and maintain in the later stage.Based on this, the device pre-adjusts according to the position parameters of the steel bars on the foundation of each prefabricated building. Specifically, when the pulley 19 moves in the slide rail 20, the movement of the pulley 19 will drive the sliding support frame to move, and the sliding support frame drives the slide rail 20 to move. When the slide rail 20 is adjusted to be directly above the steel bars, the four translation slides 21 are adjusted so that the four translation slides 21 move to the top of the specific corresponding steel bars. Due to the high degree of standardization of the construction site, the position of the steel bar distribution on the foundation can be known in advance. Therefore, in order to improve work efficiency, the positions of the slide rail 20 and the translation slide 21 can be pre-adjusted in advance, and there is no need to equip additional drive components to drive the slide rail 20 and the translation slide 21.

[0042] The reinforcement mechanism 24 includes a accommodating tube 25, a sleeve rod 26, a plurality of sleeve tubes 27 and a plurality of positioning pins 29. The interior of the accommodating tube 25 is hollow. The accommodating tube 25 is fixedly connected to a translation slide 21 in each group. The sleeve rod 26 is located inside the accommodating tube 25. The sleeve rod 26 is slidably connected to the accommodating tube 25. A plurality of sleeve tubes 27 are sleeved one by one on the outside of the sleeve rod 26, wherein the sleeve tube 27 located on the outermost side is fixedly connected to another translation slide 21 in each group. Limiting grooves 28 are formed on the accommodating tube 25 and the sleeve tube 27. A plurality of positioning pins 29 pass through the positioning grooves and are respectively screwed into the sleeve rod 26 and the sleeve tube 27. When the device is working, in order to improve the stability of the device and facilitate the determination of the relative position and relative distance between the two translation slides 21 in each group, the accommodating tube 25 is fixedly connected to one translation slide 21 in each group, and the outermost sleeve tube 27 is fixedly connected to the other translation slide 21 in each group. When the two translation slides 21 are pulled apart, according to the change in the distance between the two translation slides 21, several sleeve tubes 27 are pulled apart layer by layer under the limitation of the limit slide groove 28 and the limit pin 42. When a sleeve tube 27 is pulled to the extreme position, the positioning pin 29 will position it so that it cannot move further.

[0043] A triangular support frame 34 is formed at the bottom of the infrared laser instrument 33. The positioning monitoring assembly 30 also includes a first positioning ring 35, a second positioning ring 31, a connecting short rod 37 and a fixed gasket 38. The fixed gasket 38 is fixedly installed on the side of the translation slide 21. The connecting short rod 37 is arranged in a vertical state. The connecting short rod 37 is fixedly connected to the fixed gasket 38. Both ends of the connecting short rod 37 extend out of the translation slide 21. One end of the connecting short rod 37 is fixedly connected to the first positioning ring 35, and the other end is fixedly connected to the second positioning ring 31. The first positioning ring 35 is arranged at one end of the translation slide 21 in a horizontal state, and the second positioning ring 31 is arranged at the other end of the translation slide 21 in a horizontal state. Three first positioning notches 36 are formed on the first positioning ring 35 and are evenly spaced in the circumferential direction. The second positioning ring 31 is formed with a plurality of second positioning notches 32 that are evenly spaced in the circumferential direction. The infrared laser instrument 33 is fixedly installed on the first positioning ring 35. The triangular support frame 34 at the bottom of the infrared laser instrument 33 cooperates with the first positioning notch 36. When the device is working, the first positioning ring 35 is fixedly installed on one end of the translation slide 21, the second positioning ring 31 is fixedly installed on the other end of the translation slide 21, and the infrared laser 33 is fixedly installed on the upper side of the first positioning ring 35. The triangular support frame 34 at the bottom of the infrared laser 33 cooperates with the first positioning notch 36 formed on the first positioning ring 35. This cooperation ensures that the emitting end of the infrared laser 33 is facing upward. During the positioning and monitoring process, the infrared laser 33 locates the prefabricated building by irradiating the steel bar holes.

[0044] The positioning mechanism 39 includes a plurality of elastic retainers 40, which are arranged at equal intervals along the circumferential direction of the second positioning ring 31. Each elastic retainer 40 is fixedly connected to the second positioning notch 32. The elastic retainer 40 includes a spring 43, a conical top cap 44, a limiting shaft 45, a protective shell 46, a screw bolt 47, a support washer 41 and four limiting pins 42. The support washer 41 is fixedly installed at the second positioning notch 32 inside the second positioning ring 31. The limiting shaft 45 passes through the second positioning notch 32. The limiting shaft 45 The head end points to the center of the second positioning ring 31, the end of the limiting shaft 45 extends out of the second positioning notch 32 and the conical top cap 44 and is fixedly screwed to the head end of the limiting shaft 45, the spring 43 is sleeved on the outside of the limiting shaft 45, one end of the spring 43 is against the bottom of the conical top cap 44, and the other end is against the support gasket 41, four limiting pins 42 pass through the support gasket 41 and the second positioning notch 32 at equal intervals in the circumferential direction, the end of the limiting shaft 45 is sleeved with a protective shell 46, and the screw-on bolt 47 passes through the protective shell 46 and is fixedly installed at the end of the limiting shaft 45. When the device is working, after the translation slide 21 is located directly above the steel bar, the translation slide 21 slowly descends, and at this time, a number of elastic tightening devices 40 slowly press down. When the steel bar contacts the elastic tightening devices 40, the elastic tightening devices 40 will adjust themselves according to the diameter of the steel bar. Specifically, the steel bar contacts the conical top cap 44 and moves up along the conical surface of the conical top cap 44. At this time, the conical top cap 44 moves away from the center of the circle. The movement of the conical top cap 44 will drive the limit shaft 45 to move. One end of the spring 43 abuts against the lower end of the conical top cap 44, and the other end abuts against the support gasket 41. When the conical top cap 44 moves, the limit shaft 45 moves. During the movement, the spring 43 will be compressed and deformed. When the device is positioned and detached from the steel bar, the compressed spring 43 pushes the conical top cap 44 to reset due to elastic reset. During the movement of the conical top cap 44, the four limit pins 42 assist in limiting the limit shaft 45. The four limit pins 42 prevent the limit shaft 45 from moving during the movement, thereby improving the stability of the positioning mechanism 39. The protective shell 46 is fixed to the tail of the limit shaft 45 by the screw-on bolts 47. The protective shell 46 encloses the four limit pins 42 to protect the limit pins 42 from being contaminated by dust on the construction site, thereby improving the sensitivity of the device.

[0045] The alarm 48 includes a battery 50, a sounder 51 and four indicator lights 49. The four indicator lights 49 are vertically fixedly mounted on the upper end of the support platform 2. The battery 50 is located next to one of the indicator lights 49. The battery 50 is fixedly mounted on the upper end of the support platform 2. The sounder 51 is located next to one of the indicator lights 49. The sounder 51 is fixedly mounted on the upper end of the support platform 2. The indicator light 49, the infrared laser instrument 33 and the buzzer 51 are all electrically connected to the controller. When the infrared laser instrument 33 detects that the positioning is not successful, the signal is transmitted to the controller, and the controller controls the indicator light 49 to flash. Specifically, each indicator light 49 corresponds to an infrared laser instrument 33. When the infrared laser instrument 33 detects that the positioning is not successful, the infrared laser instrument 33 transmits the signal to the controller. The controller set in the indicator light 49 corresponding to the infrared laser instrument 33 will receive the signal and control the indicator light 49 to flash. When the indicator light 49 flashes, the signal is transmitted to the buzzer 51 through the controller, and the buzzer 51 will emit a warning sound to prompt. At this time, the operator can fine-tune the assembly template according to the flashing indicator light 49. Since the indicator light 49 and the buzzer 51 have low energy consumption, it is only necessary to set a battery 50 separately to power the indicator light 49 and the buzzer 51.

[0046] The translation mechanism also includes a positioning bolt 22 and two auxiliary bolts 23. The positioning bolt 22 passes through the center of gravity of the support rod 14 and is screwed on the lifting slider 10. The two auxiliary bolts 23 are symmetrically arranged in the vertical direction of the positioning bolt 22. The two auxiliary bolts 23 pass through the support rod 14 and are screwed on the lifting slider 10. Due to different construction standards of each construction site, there are two forms of cooperation between the bottom module of the prefabricated building and the foundation. One is that the bottom module is provided with steel bars and the foundation is provided with steel bar holes. The other is that the bottom module is provided with steel bar holes and the foundation is provided with steel bars. In order to adapt to these two forms, a positioning bolt 22 is provided at the connection between the support rod 14 and the lifting slider 10. When switching the assembly form, it is only necessary to pull out the positioning bolt 22 and the two auxiliary bolts 23, turn the support rod 14 around the center of gravity by 180 degrees, and then insert the positioning bolt 22 and the two auxiliary bolts 23. The two auxiliary bolts 23 ensure that the support rod 14 will not move after being fixed in position, thereby improving the stability of the device.

[0047] Working principle of the device: take the foundation provided with steel bars and the bottom module provided with steel bar holes as an example, when the device is working, the carrying trolley 1 approaches and presses against the part of the foundation exposed to the ground, the motor 7 works to drive the screw rod 9 to rotate, the screw rod 9 rotates in the base 11 to drive the lifting slider 10 to move up and down, and the lifting slider 10 is adjusted to an appropriate position. At this time, the two support arms 16 are located above the steel bars. The two support arms 16 include the four steel bars used for positioning. The device will position the four steel bars. Specifically, the vertical direction is specified as the Z axis, the moving direction of the slide rail 20 is the X axis, and the moving direction of the translation slide 21 is the Y axis. When the corresponding position of a certain position positioning point on the three axes is determined, this position is determined. At this time, the lifting slider 10 has moved the Y axis of the steel bar The coordinate point is positioned, the operator moves the sliding support frame 18, and the slide rail 20 connected to the sliding support frame 18 moves to the top of the corresponding steel bar. At this time, the slide rail 20 positions the X-axis coordinate point of the steel bar, and finally moves the translation slide 21. When moving the translation slide 21, in order to ensure the relative position and relative distance between the two translation slides 21 in each group, moving the translation slide 21 will cause the accommodating tube 25, the sleeve rod 26 and the sleeve tube 27 to produce relative displacement, and several sleeve tubes 27 are withdrawn layer by layer. When each sleeve tube 27 moves to the extreme position, the positioning pin 29 will limit the sleeve tube 27 at this time to ensure that the several sleeve tubes 27 will not separate from each other. When the accommodating tube 25, the sleeve rod 26 and the sleeve tube 27 are moved, the translation slide 21 moves To the top of the steel bar, at this time, the translation slide 21 locates the Y-axis coordinate point of the steel bar. After the coordinate point of the steel bar in the spatial coordinate axis is uniquely defined, the device is operated to perform positioning monitoring on the prefabricated building. Specifically, when the lower end of the translation slide 21 is aligned with the steel bar, in order to adapt to steel bars of different specifications, the elastic tightener 40 has self-adaptive adjustability. When the second positioning ring 31 of the steel bar is sleeved on the steel bar, as the steel bar is slowly inserted into the second positioning ring 31, the elastic tightener 40 starts to work. At this time, the conical top cap 44 moves to a position away from the center of the circle, and the limiting shaft 45 is fixedly connected to the conical top cap 44. The limiting shaft 45 also moves to a position away from the center of the circle. Since one end of the spring 43 is against the bottom end of the conical top cap 44, and the other end is against the support gasket 41, as The conical top cap 44 moves in the direction away from the center of the circle, and the spring 43 is deformed by the force. When the positioning monitoring is completed, the device is separated from the steel bar, and the compressed spring 43 will return to its original position under the action of the elastic force, driving the other parts in the elastic tightener 40 to return to their original positions, and prepare for the next positioning. During the movement of the limit shaft 45, in order to prevent the limit shaft 45 from moving and causing positioning errors, the four limit pins 42 limit the movement of the limit shaft 45 to ensure the accuracy of the positioning result. Due to the high dust on the construction site, the protective shell 46 is used to protect the limit pins 42 from being contaminated by dust, which improves the accuracy of the device and facilitates later inspection and maintenance. After several conical top caps 44 have positioned and limited the steel bars, the infrared laser instrument 33 located on the first positioning ring 35 starts to operate.The light emitted by the infrared laser instrument 33 illuminates the steel bar hole of the upper assembly base plate. When the light does not penetrate into the bottom of the steel bar hole, the light path is short. The infrared laser instrument 33 captures this signal and transmits it to the controller. After receiving the signal, the controller controls the corresponding indicator light 49 to flash. At the same time, the controller is also electrically connected to the buzzer 51. When this signal commands the indicator light 49 to flash, this signal is transmitted to the buzzer 51 through the controller to control the buzzer 51 to roar. From the operator's perspective: when positioning is not successful, the indicator light 49 that has not been successfully positioned flashes, and the buzzer 51 roars to remind the operator to fine-tune the bottom module; when the light penetrates into the bottom of the steel bar hole, the contact point between the light and the bottom template suddenly changes from the surface of the bottom template to the bottom of the steel bar hole, and the infrared laser instrument 33 captures this signal. At this time, the irradiation distance of the light becomes longer than the previous distance. When the four infrared laser instruments 33 capture this mutation signal at the same time, that is, at this time, all the four steel bar holes are successfully positioned. After the positioning is successful, the infrared laser instrument 33 captures this signal and transmits this signal to the controller. After receiving the signal, the controller controls the corresponding indicator light 49 to execute the instruction. At this time, the corresponding indicator light 49 stops flashing. Similarly, the controller is also electrically connected to the sounder 51. When this signal commands the indicator light 49 to stop flashing, this signal is transmitted to the sounder 51 through the controller to control the sounder 51 to roar. From the operator's perspective: when the positioning is successful, all the indicator lights 49 stop flashing, and the sounder 51 stops roaring. At this time, the positioning is accurate. The operator can notify the crane to control the bottom module to descend, and the carrying trolley 1 can be pulled out during the descent. Due to different construction standards on construction sites, there is another form of foundation and bottom module corresponding to prefabricated buildings, that is, the bottom module is provided with steel bar holes, and the foundation is provided with steel bars. At this time, the positioning bolts 22 and the two auxiliary bolts 23 are pulled out, and the support rod 14 is turned 180 degrees around the center of gravity, and then the positioning bolts 22 and the two auxiliary bolts 23 are inserted. After the flip, the positioning monitoring device can perform positioning monitoring on the inverted steel bars and steel bar holes, and the monitoring principle does not change. The two auxiliary bolts 23 set in a symmetrical state ensure that the support rod 14 will not move after the fixed position, thereby improving the stability of the device.
