When the auxiliary device is in use, the wall panel 4 to be assembled is placed inside the assembly frame 3, and the wall panel 4 to be assembled is clamped by the assembly frame 3 by adjusting the limiting plate 305 and the sliding plate 101. According to the actual size and width of the wall panel 4 to be assembled, the sliding plate 101 and the limiting plate 305 are adjusted simultaneously to adapt to different types of wall panels 4 to be assembled. Then, the assembly frame 3 and the limiting plate 305 are fixed, and the sliding plate 101 and the support 1 are fixed simultaneously to keep the position stable, so that the assembly frame 3 and the support 1 have wide adaptability and improve the working effect.

[0055] In addition, a synchronous motor 104 is installed at the rear end of the support 1. The synchronous motor 104 is fixedly connected to the support 1. The motor shaft of the synchronous motor 104 is connected to a rotating shaft through a coupling, and the rotating shaft is fixedly connected to the middle of the interior of the spiral cam 102. The spiral cam 102 is rotatably connected to the support 1 through a bearing. By driving the synchronous motor 104 to drive the spiral cam 102 to rotate, the limiting roller 302 and the transmission arm 301 are driven to move. The transmission arm 301 and the assembly frame 3 are limited by the auxiliary T-shaped sleeve 2. During the stepped movement and conveying work, during the rotation of the spiral cam 102, the limiting roller 302 is limited by gravity and the guiding track to keep the position stable. The outermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the highest position, while the innermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the lowest position, which is convenient for feeding.

[0058] Specifically, when the auxiliary device is in use, the wallboard 4 to be assembled is placed inside the assembly rack 3, and the wallboard 4 to be assembled is clamped by the assembly rack 3 by adjusting the limiting plate 305 and the sliding plate 101. According to the actual size and width of the wallboard 4 to be assembled, the sliding plate 101 and the limiting plate 305 are adjusted simultaneously to adapt to different types of wallboards 4 to be assembled. Then, the assembly rack 3 and the limiting plate 305 are fixed, and the sliding plate 101 and the bracket 1 are fixed simultaneously to keep the position stable, so that the assembly rack 3 and the bracket 1 have wide adaptability and improve the working effect. After fixing, the bracket 1 and the wallboard 4 to be assembled at the upper end are pushed through the universal wheels 103 to move the wallboard 4 to be assembled close to the installation position for subsequent operations. The synchronous motor 104 is driven to drive the spiral cam 102 to rotate, driving the limiting roller 302 and the transmission arm 301 to move. The transmission arm 301 and the assembly rack 3 are limited by the auxiliary T-shaped sleeve 2, and the auxiliary T-shaped sleeve 2 is limited by the positioning tube 202 to rise in a uniform stepped manner, keeping the position of the wallboard 4 to be assembled stable while approaching the assembly position, and the structural position is stable. The stable feeding work can be realized through the synchronous motor 104, and the driving work is carried out through the limiting roller 302. In the stepped moving and conveying work, during the rotation of the spiral cam 102, the limiting roller 302 is limited by gravity and the guiding track to keep the position stable. The outermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the highest position, and the innermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the lowest position, which is convenient for feeding.

[0059] In order to solve the problems that in the actual use process of the existing auxiliary installation device, it is difficult to fully detect the position of the wallboard and the anti-dropping effect is not good, please refer to Figure 1 - Figure 4 、 Figure 6 This embodiment provides the following technical solutions:

[0060] A pressure measuring plate 303 is provided at the front end of the assembly rack 3, and a balance detection plate 304 is installed on the rear end face of the assembly rack 3. During the work, while the assembly rack 3 is feeding and assisting, the preliminary detection work is carried out through the balance detection plate 304 at the rear end of the assembly rack 3, and the pillow-type weighing sensors at the upper and lower ends can detect the position of the wallboard 4 to be assembled.

[0061] In addition, an electric cylinder 3031 is installed between the pressure measuring plate 303 and the assembly frame 3, and an auxiliary wheel 3032 is installed above the pressure measuring plate 303. An anti-slip pad is provided on the surface of the auxiliary wheel 3032. The auxiliary wheel 3032 is rotatably connected to the electric cylinder 3031 through a bearing. The pressure sensor between the pressure measuring plate 303 and the auxiliary wheel 3032 monitors the pressure on both sides of the auxiliary wheel 3032, thereby judging the position between the assembly frame 3 and the wall panel 4 to be assembled. Then, the laser ranging probe 306 monitors the distances between both sides of the assembly frame 3 and the installation position.

[0062] In addition, a wall panel 4 to be assembled is provided above the assembly frame 3. The wall panel 4 to be assembled is clamped in the assembly frame 3 through the balance detection plate 304 and the auxiliary wheel 3032. Laser ranging probes 306 are provided on both outer sides of the assembly frame 3. The distances between both sides of the assembly frame 3 and the installation position are monitored through the laser ranging probes 306 to monitor the assembly frame 3, improve the detection effect, improve the detection accuracy, and thus make the judgment effect of the controller 5 better.

[0063] In addition, a controller 5 is further provided inside the assembly frame 3. The input ends of the controller 5 are respectively connected to the output ends of the laser ranging probe 306, the pressure measuring plate 303, and the balance detection plate 304;

[0064] The laser ranging probe 306 is used to monitor the distances between both sides of the assembly frame 3 and the installation position;

[0065] A pressure sensor is provided between the pressure measuring plate 303 and the auxiliary wheel 3032, and the pressure sensor is used to monitor the pressure on both sides of the auxiliary wheel 3032;

[0066] Pillow block type load cells are provided at both the upper and lower ends of the balance detection plate 304. The position of the wall panel 4 to be assembled is detected through the pillow block type load cells. The upper and lower pillow block type load cells can detect the position of the wall panel 4 to be assembled, thereby detecting the balance between the wall panel 4 to be assembled and the assembly frame 3. The pillow block type load cell can be installed on the balance detection plate 304 with four screws using the PFCL201 pressure sensor;

[0067] The controller 5 judges the data detected by the balance detection plate 304, the laser ranging probe 306, and the pressure measuring plate 303 to detect whether the positions of the wall panel 4 to be assembled and the assembly frame 3 are balanced, improve the detection effect, improve the detection accuracy, and thus make the judgment effect of the controller 5 better;

[0068] The output end of the controller 5 is connected to the input end of the electric cylinder 3031 to control the telescopic operation of the electric cylinder 3031. Different electric cylinders 3031 extend to adjust the positions of the auxiliary wheels 3032 at different positions, thereby adjusting the position between the bottom end of the wallboard 4 to be assembled and the assembly rack 3, performing anti-dropping operations, improving position stability, and facilitating the exterior wall assembly work.

[0069] Specifically, during the work, while loading and assisting through the assembly rack 3, preliminary detection work is carried out through the balance detection plate 304 at the rear end of the assembly rack 3. The pillow block load cells at the upper and lower ends can detect the position of the wallboard 4 to be assembled, thereby detecting the balance between the wallboard 4 to be assembled and the assembly rack 3. Then, through the pressure sensors between the pressure plate 303 and the auxiliary wheels 3032, the pressure magnitudes on both sides of the auxiliary wheels 3032 are monitored to judge the position between the assembly rack 3 and the wallboard 4 to be assembled. Additionally, the distances between both sides of the assembly rack 3 and the installation position are monitored through the laser ranging probes 306 to monitor the assembly rack 3, improving the detection effect and accuracy. As a result, the judgment effect of the controller 5 is better, and the electric cylinders 3031 perform telescopic operations. Different electric cylinders 3031 extend to adjust the positions of the auxiliary wheels 3032 at different positions, thereby adjusting the position between the bottom end of the wallboard 4 to be assembled and the assembly rack 3, performing anti-dropping operations, improving position stability, and facilitating the exterior wall assembly work.

[0070] Specifically, please refer to Figure 7 - Figure 13, the locking device 6 includes: a mounting bracket 601, one end of the mounting bracket 601 close to the outer wall of the bracket 1 is embedded in the housing of the bracket 1. A guiding groove 606 is provided at the center of the top of the mounting bracket 601. An installation groove 6018 is provided in the housing of the mounting bracket 601. A receiving groove 6014 is provided on one side of the mounting bracket 601 embedded in the housing of the bracket 1. A pressing key 602 is movably arranged in the installation groove 6018, and the pressing key 602 is connected to the inner wall of the installation groove 6018 through a return spring 6015. The pressing key 602 is connected to a pin head 6017 through a first connecting rod 6016. An L-shaped guiding member 609 is movably arranged in the guiding groove 606, and a threaded hole 6013 is provided on the vertical section of the L-shaped guiding member 609. A driving screw 607 is fixedly provided at the center of the driving disc 605, and one end of the driving screw 607 away from the driving disc 605 extends into the threaded hole 6013 and is in threaded engagement therewith. A handle 604 is fixedly provided on the side of the driving disc 605 away from the driving screw 607, and a number of groups of pin holes 603 are provided on the driving disc 605. A locking head 608 is fixedly provided at the end of the horizontal section of the L-shaped guiding member 609. An anti-detachment plug 6012 is fixedly provided on the vertical section of the L-shaped guiding member 609. A diagonal brace 6011 is provided between the locking head 608 and the L-shaped guiding member 609. One end of the locking head 608 extending into the housing of the bracket 1 is in the structure of a locking tooth head 6010.

[0071] When adjusting the distance between the two groups of brackets 1, by pushing the pressing key 602 to compress the return spring 6015, so that the pin head 6017 installed on the first connecting rod 6016 is separated from the pin hole 603 on the driving disc 605, the driving disc 605 is no longer restricted. At this time, by driving the driving disc 605 to rotate through the handle 604, the driving screw 607 rotates synchronously, and under the action of the threaded hole 6013, the L-shaped guiding member 609 slides along the guiding groove 606 until the locking head 608 is separated from the sliding plate 101. Then, the two groups of brackets 1 can be pushed by the universal wheels 103 to move away from / close to each other until the distance meets the requirements. Then, by driving the driving disc 605 to rotate in the reverse direction through the handle 604 again until the locking tooth head 6010 provided on the locking head 608 is engaged with the tooth groove 105 on the sliding plate 101, release the pressing key 602 and drive by the return spring 6015, the pin head 6017 enters the pin hole 603 to prevent the driving disc 605 from deflecting. Then, the adjusting limit plate 305 and the sliding plate 101 can clamp the wallboard 4 to be assembled through the assembly frame 3. According to the actual size and width of the wallboard 4 to be assembled, adjust the sliding plate 101 and the limit plate 305 at the same time to adapt to different types of wallboards 4 to be assembled and keep the position stable.

[0072] In this invention, the main advantages of the locking device include:

[0073] 1. Enhanced position stability: The locking device effectively fixes the positions of the bracket and the sliding plate through components such as the mounting bracket, guide groove, pressing key, and driving disc. This design ensures that the assembly rack remains stable during the assembly process, preventing the wall panel from being unstable or falling off due to movement or vibration.

[0074] 2. Ease of operation: The design of the locking device makes it simple and controllable to adjust the distance between the brackets. Through the combined operation of the pressing key and the driving disc, the working position of the device can be precisely adjusted to adapt to wall panels of different types and sizes to be assembled.

[0075] 3. Improved safety: The locking device can reliably lock the position after adjustment, using a return spring and a pin head to ensure that the device will not shift or loosen due to external influences. This design effectively reduces the likelihood of accidental events during the working process and enhances the safety of the installation process.

[0076] 4. Adaptability and reliability: The structural design of the locking device has been carefully optimized to make it have good adaptability and stability. Regardless of the working environment, this device can maintain an efficient working state to ensure the safety and stability of the assembly rack and the wall panel.

[0077] Therefore, as a key component in this invention, the locking device not only simplifies the operation steps of the wall panel assembly process but also significantly improves the position stability and safety of the wall panel during the assembly process.

[0078] In addition, in order to ensure the accuracy of the positioning of the auxiliary device, a monitoring unit is provided. The monitoring unit includes: a pressure sensor installed at the position where the spiral cam 102 contacts the limiting roller 302 to detect the load borne between the spiral cam 102 and the limiting roller 302;

[0079] A first rotational speed sensor installed on the shaft of the synchronous motor 104 for real-time monitoring of the rotational speed of the spiral cam 102;

[0080] A second rotational speed sensor installed on the rotating shaft of the spiral cam 102 to ensure matching of the rotational speed with that of the synchronous motor 104;

[0081] An angle sensor installed on the shaft of the spiral cam 102 to monitor the rotational angle of the spiral cam 102;

[0082] A temperature sensor installed on the surface of the spiral cam 102 to monitor the temperature of the spiral cam 102 and its related components;

[0083] An alarm, and the alarm is arranged on the bracket 1;

[0084] The controller 5 is electrically connected to the pressure sensor, the first rotational speed sensor, the second rotational speed sensor, the angle sensor and the alarm respectively. The controller 5 controls the alarm to work based on the pressure sensor, the first rotational speed sensor, the second rotational speed sensor and the angle sensor, including:

[0085] Step 1: The controller calculates the working state index of the spiral cam 102 based on the pressure sensor, the first rotational speed sensor, the second rotational speed sensor, the angle sensor and formula (1):

[0086]

[0087] where X is the working state index of the spiral cam 102, F1 is the detected value of the pressure sensor, F2 is the maximum load-bearing capacity designed for the spiral cam 102, T1 is the detected value of the temperature sensor, T2 is the maximum working temperature of the spiral cam 102, Δ T is the sensitivity factor of the temperature change of the material of the spiral cam 102, θ1 is the detected value of the angle sensor, θ2 is the maximum allowable rotation angle of the spiral cam 102, α is the material strength influence index of the spiral cam 102, K is the sensor accuracy influence index, and μ is the friction coefficient between the spiral cam 102 and the limiting roller 302;

[0088] Step two: The controller 5 compares the working state index of the spiral cam 102 with the preset working state index. If the working state index of the spiral cam 102 is less than the preset working state index, the alarm gives an alarm.

[0089] Specifically, the goal of this formula is to monitor the working state of the spiral cam 102 in real time through the data collected by multiple sensors and trigger an alarm when the working state does not meet the requirements. It combines various factors such as pressure, rotational speed, angle, temperature, and friction coefficient to dynamically evaluate the performance of the spiral cam. The following is a detailed explanation of each part of the formula and how they are combined with the data discussed previously.

[0090] 1. Temperature-related terms:

[0091]

[0092] T1: The current temperature (the value detected by the temperature sensor), which reflects the actual working temperature of the spiral cam and its related components.

[0093] T2: The maximum working temperature of the spiral cam (the set design value), which is the upper temperature limit for the normal operation of the spiral cam.

[0094] Δ T : Temperature change sensitivity factor (which may be adjusted according to factors such as material properties), representing the response of the material to temperature changes.

[0095] Among them, this term expresses the influence of temperature difference on the working state of the spiral cam. Temperature changes will cause the expansion or contraction of the material, thereby affecting precision and durability. When the actual temperature approaches or exceeds the maximum working temperature, the working state index X will decrease significantly, indicating that the performance of the spiral cam is impaired.

[0096] 2. Coefficient of friction and sensor accuracy:

[0097]

[0098] μ1: Coefficient of friction (deduced from the contact force between the pressure sensor and the limit roller). The magnitude of the frictional force directly affects the precision and life of the spiral cam.

[0099] K: Sensor accuracy influence index, used to reflect the influence of sensor error or the measurement accuracy of the system on the working state.

[0100] α: Material strength influence index, used to adjust the influence of material strength on the life and precision of the spiral cam.

[0101] Among them, the frictional force affects the motion precision of the spiral cam. High friction will lead to more wear and temperature rise, thereby reducing the precision and life of the spiral cam. At the same time, the influence of sensor accuracy on data acquisition is also considered. If the accuracy of the sensor is low, it may lead to error accumulation, thus affecting the judgment of the working state.

[0102] 3. Load and angle related terms:

[0103]

[0104] F1: Actual load detected by the pressure sensor (pressure applied to the spiral cam), which directly affects the working state of the spiral cam. If the load is too large, it may cause the spiral cam to deform or wear prematurely.

[0105] F2: Maximum load-bearing capacity designed for the spiral cam, which is the maximum load that the spiral cam can withstand without failure.

[0106] θ1: Current angle measured by the angle sensor, representing the actual rotation angle of the spiral cam.

[0107] θ2: Maximum rotation angle allowed for the spiral cam. Exceeding this angle may cause the device to be overloaded or jammed.

[0108] Among them, the function of this item is to calculate the combined influence of the load and the rotation angle. By using sine and cosine functions, the relationship between the load and the angle is considered. If the load is too high or the rotation angle exceeds the allowable range, the working state index X of the spiral cam will decrease significantly.

[0109] In summary, by combining various factors such as temperature, load, friction, and angle, a working state index X is dynamically calculated to evaluate the current working state of the spiral cam.

[0110] The influence of various factors is compound, which means that the deterioration of one factor (such as too high temperature, too large load, etc.) will lead to a significant decrease in the working state index. Therefore, the controller will calculate the current working state index X and compare it with the preset normal working state index. If X is less than the preset value, it means that the working state of the spiral cam does not meet the requirements (there may be problems such as excessive load, too high temperature, angle deviation, etc.). At this time, the alarm will be activated to remind the operator to take measures.

[0111] Various sensors (pressure sensor, temperature sensor, angle sensor, rotational speed sensor) collect real-time data and feed it back to the controller. The controller calculates the working state index based on Formula 1 and judges whether to alarm according to the set threshold.

[0112] In this way, the system can monitor the working state of the spiral cam in real time and provide necessary alarm signals to avoid a decrease in accuracy or damage caused by improper operation or equipment failure.

[0113] This formula dynamically evaluates the working state of the spiral cam by comprehensively using the data of various sensors and using complex mathematical models (including factors such as temperature, load, friction, and angle). Its core idea is to evaluate the performance of the spiral cam based on real-time data monitoring and preset thresholds, so as to ensure its operation in the best state and avoid damage or accuracy decrease caused by overloading, too high temperature, too large angle, etc.

[0114] Working principle: When the auxiliary device is in use, the wall panel 4 to be assembled is placed inside the assembly rack 3. The wall panel 4 to be assembled is clamped by the assembly rack 3 by adjusting the limiting plate 305 and the sliding plate 101. According to the actual size and width of the wall panel 4 to be assembled, the sliding plate 101 and the limiting plate 305 are adjusted simultaneously to adapt to different types of wall panels 4 to be assembled. Then, the assembly rack 3 and the limiting plate 305 are fixed, and the sliding plate 101 and the bracket 1 are fixed at the same time to keep the position stable, so that the assembly rack 3 and the bracket 1 have wide adaptability and improve the working effect. After fixing, the bracket 1 and the wall panel 4 to be assembled at the upper end are pushed by the universal wheels 103 to move, so that the wall panel 4 to be assembled is close to the installation position for subsequent operations. The synchronous motor 104 is driven to drive the spiral cam 102 to rotate, driving the limiting roller 302 and the transmission arm 301 to move. The transmission arm 301 and the assembly rack 3 are limited by the auxiliary T-shaped sleeve 2, and the auxiliary T-shaped sleeve 2 is limited by the positioning tube 202 to rise in a uniform stepped manner. While approaching the assembly position, the position of the wall panel 4 to be assembled is kept stable and the structural position is stable. Stable feeding work can be achieved through the synchronous motor 104, and transmission work is carried out through the limiting roller 302. In the stepped movement and conveying work, during the rotation of the spiral cam 102, the limiting roller 302 is limited by gravity and the guiding track to keep the position stable. The outermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the highest position, while the innermost spiral cam 102 conveys the transmission arm 301 and the limiting roller 302 to the lowest position, which is convenient for feeding. While feeding and assisting through the assembly rack 3, preliminary detection work is carried out through the balance detection plate 304 at the rear end of the assembly rack 3. The pillow-type weighing sensors at the upper and lower ends can detect the position of the wall panel 4 to be assembled, so as to detect the balance degree between the wall panel 4 to be assembled and the assembly rack 3. Then, through the pressure sensor between the pressure plate 303 and the auxiliary wheel 3032, the pressure magnitudes on both sides of the auxiliary wheel 3032 are monitored, so as to judge the position between the assembly rack 3 and the wall panel 4 to be assembled. Then, the distance between both sides of the assembly rack 3 and the installation position is monitored through the laser ranging probe 306 to monitor the assembly rack 3, improving the detection effect and the detection accuracy, so that the judgment effect of the controller 5 is better, and the electric cylinder 3031 performs telescopic work. Different electric cylinders 3031 extend to adjust the positions of the auxiliary wheels 3032 at different positions, so as to adjust the position between the bottom end of the wall panel 4 to be assembled and the assembly rack 3 for anti-dropping operation, improving the position stability and being beneficial to the exterior wall assembly work.
