Abstract

When the scaffold safety monitoring device for construction is used, the lower portion of the device is moved to a designated position, then articles to be used are gradually carried to the top of the upper portion of the device, and finally a worker can conduct construction on the top of the upper portion of the device; the device lower part comprises the first weighing device, and the first weighing device can monitor the weight change of the scaffold safety monitoring device, so that overload can be prevented; due to the fact that the device lower portions are equal in height in the vertical direction, if the ratio of the numerator to the denominator is smaller than one half, the gravity center is located on the device lower portion, the lower the gravity center is, the longer the pushing distance is needed when the gravity center moves out of a supporting point, the more work is needed, and the larger the energy needed for pushing over the object is. The object is more stable, so that the safety of the scaffold can be judged according to the height of the gravity center; in general, by using the scaffold safety monitoring device for construction, overload can be prevented, and the height of the gravity center of the scaffold can be judged.

Description

Technical Field

[0002] A scaffold is a working platform erected to ensure the smooth progress of each construction process, which can solve the problems of vertical and horizontal transportation and assist workers in working at heights; since the height of the scaffold is usually relatively high, therefore, in order to ensure the safety of the staff, the safety of the scaffold during use deserves our attention to prevent accidents.

[0003] During the use of the scaffold, pedals are placed on the top, and the pedals carry staff and items. Usually, the scaffold is a framework composed of multiple rod bodies, which results in the weight on the top of the scaffold being much greater than the weight at the bottom of the scaffold. Without fixing the bottom of the scaffold, the heavier the weight on the top of the scaffold, the higher the center of gravity of the scaffold, and the easier it is to tip over; in addition, although the load-bearing range of some scaffolds is clearly defined, the staff cannot visually observe the total weight of various items and themselves on the top of the scaffold, which leads to the use of some scaffolds still being used after overloading, not being safe enough. Therefore, it is urgent to design a device that can monitor the safety of the scaffold. Content of the Utility Model

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention discloses a safety monitoring device for a construction scaffold, which is used in cooperation with the scaffold, including a lower part 1 of the device and an upper part 2 of the device installed on the upper surface of the lower part 1 of the device. The weights of the lower part 1 and the upper part 2 of the device are known and the heights in the vertical direction are the same. The lower part 1 of the device includes a first weighing device 11, which is used to monitor the weight change of the safety monitoring device of the scaffold. Taking the weight of the upper part 2 of the device as the numerator and the total weight of the upper part 2 and the lower part 1 of the device as the denominator, it is determined whether the center of gravity of the safety monitoring device of the scaffold exceeds half of the total height of the safety monitoring device of the scaffold by whether the ratio of the numerator to the denominator exceeds one-half, so as to judge whether the scaffold is safe.

[0034] During actual use, move the lower part 1 of the device to the designated position, then gradually carry the items to be used to the top of the upper part 2 of the device. Finally, the staff can perform construction on the top of the upper part 2 of the device. Since the first weighing device 11 is included in the lower part 1 of the device and the first weighing device 11 can monitor the weight change of the scaffolding safety monitoring device, overloading can be prevented. Since the lower part 1 of the device and the lower part 2 of the device are of the same height in the vertical direction, when the ratio of the weight of the upper part 2 of the device as the numerator to the total weight of the upper part 2 and the lower part 1 of the device as the denominator exceeds one-half, it can be determined that the weight of the upper part 2 of the device exceeds that of the lower part 1, and the center of gravity is located on the upper part 2 of the device, that is, the center of gravity is located on the upper part of the scaffolding safety monitoring device used in this construction, which is not stable enough and is prone to tilting and overturning when shaking. If the ratio of the numerator to the denominator is less than one-half, the center of gravity is located on the lower part 1 of the device. And the lower the center of gravity, the longer the distance that needs to be pushed to move the center of gravity outside the support point, the more work is required, that is, the more energy is required to overturn this object, and the more stable this object is. Thus, the safety of the scaffolding can be judged by the height of the center of gravity. Generally speaking, by using the scaffolding safety monitoring device used in this construction, overloading can be prevented and the height of the center of gravity of the scaffolding can be judged.

[0035] Since the staff will exert force with both the hands on the upper body and the feet on the lower body during the climbing process, there will be a situation where the hands are on the upper part 1 of the device and the feet are on the lower part 2 of the device. This leads to different weight changes in the upper part 1 and the lower part 2 of the device. In order to more accurately monitor the weight changes of the lower part 1 and the upper part 2 of the device, the following design is carried out in this embodiment. Specifically, the lower part 1 of the device further includes a first frame body 12. The bottom of the first frame body 12 is connected to the first weighing device 11, and the top is connected to the upper part 2 of the device. The upper part 2 of the device includes a second weighing device 21 and a second frame body 22. The bottom of the second weighing device 21 is connected to the first frame body 12 for monitoring the weight change of the upper part 2 of the device. The bottom of the second frame body 22 is connected to the second weighing device 21, and the top is used to carry the staff and items.

[0036] Through the design of the above structure, when the staff climbs on the first frame body 12, only the weight monitored by the first weighing device 12 changes, only the denominator changes, and the center of gravity is always located on the lower part 1 of the device. When the staff climbs on the second frame body 22, the weights monitored by the first weighing device 11 and the second weighing device 21 change simultaneously and in the same amount, the numerator and the denominator change simultaneously and in the same amount, and the center of gravity moves upward. When the staff is at the junction of the first frame body 12 and the second frame body 22, the weight change monitored by the first weighing device 11 is the weight of the staff, and the weight change monitored by the second weighing device 21 is the force exerted by the staff's hands on the upper part 2 of the device, and the weight of the upper part 2 of the device can be judged more accurately.

[0037] It should be noted that the specific types and models of the first weighing device 11 and the second weighing device 21 are not limited in this application. The first weighing device 11 and the second weighing device 21 can be of the same type and model of weighing equipment, or different types and models of weighing equipment, and can be flexibly selected according to actual needs. Similarly, the specific structures of the first frame 12 and the second frame 22 are not limited in this application, and can be selected according to the actual situation of the construction site, as long as the above technical features are satisfied. In addition, even without the second weighing device 22, after the staff climbs to the top of the upper part 2 of the device completely, the comparison between the numerator and the denominator can be carried out to determine whether the center of gravity of the scaffolding safety monitoring device used in this construction is located in the lower part 1 or the upper part 2 of the device.

[0038] Refer to the appendix Figure 3 and the appendix Figure 4 , during the use of the scaffolding, it is necessary to climb back and forth and bear a large weight. In order to enable each component in the scaffolding safety monitoring device used in this construction to be replaced after being damaged, the following design is continued in this embodiment. Specifically, a plurality of first connecting parts 3 are provided at the tops of the first weighing device 11, the first frame 12, the second weighing device 21, and the second frame 22, and a plurality of second connecting parts 4 are provided at the bottoms. The plurality of second connecting parts 4 respectively correspond to the plurality of first connecting parts 3, and the two adjacent components up and down can be detachably connected through the cooperation of the first connecting part 3 and the second connecting part 4.

[0039] Through the design of the above structure, not only can each component in the scaffolding safety monitoring device used in this construction be disassembled and replaced, but also the overall height of the scaffolding safety monitoring device used in this construction can be adjusted by changing the number of the first frame 12 and the second frame 22, so as to carry out construction operations at different heights, and the application range is wider.

[0040] Refer to the appendix Figure 1 , since the scaffolding safety monitoring device used in this construction includes a plurality of frames and a weighing device is provided in the middle, in order to prevent the joints of each component from affecting the climbing of the staff, the following design is carried out in this embodiment. Specifically, a plurality of groups of linearly arranged extension plates 5 are provided on the left and right sides of the first frame 12 and the second frame 22 in the vertical direction. Each group of extension plates 5 is composed of two extension plates 5 arranged opposite to each other front and back. A handle 6 is provided between the two extension plates 5 in the same group, so that the staff can climb up through the handle 6 and prevent being hindered during the climbing process.

[0041] Through the design of the above structure, the handle 6 is significantly located outside the edges of the first weighing device 11, the first frame 12, the second weighing device 21, and the second frame 22, enabling the staff to climb up unimpeded, which is safer and more convenient.

[0042] See the appendix Figure 1 and the appendix Figure 5 , after the staff climbs to the top of the upper part 2 of the device, it is not convenient to observe the weight changes of the first weighing device 11 and the second weighing device 21. Even after the observation is completed, it is necessary to compare the above-mentioned numerator and denominator, and the operation is cumbersome. To solve the above problems, the following design is carried out in this embodiment. Specifically, the upper part 2 of the device further includes an alarm device 7. The alarm device 7 includes a fixing plate 71, a controller 72, a buzzer 73, and a warning light 74. The fixing plate 71 is installed on the second weighing device 21; the controller 72 is installed on the fixing plate 71. Both the first weighing device 11 and the second weighing device 12 are electrically connected to the controller 72, and can monitor the ratio of the numerator and denominator and send a signal when the ratio of the numerator and denominator is greater than one-half; the buzzer 73 is installed on the fixing plate 71 and can receive the signal sent by the controller 72 and emit a beep, thereby reminding the staff that the scaffolding is not safe at this time; the warning light 74 is installed on the fixing plate 71 and can receive the signal sent by the controller 72 and start to flash, thereby reminding the staff that the scaffolding is not safe at this time.

[0043] Through the design of the above structure, when the center of gravity of the scaffolding safety monitoring device used in this construction is located at the upper part 2 of the device, the alarm device 7 can automatically give an alarm, that is, the buzzer 73 emits a beep. In addition, a warning light 74 is also set in this embodiment as a double insurance and reminder. After the buzzer 73 or the warning light 74 is accidentally damaged, the other component can still work normally to remind the staff to pay attention as much as possible.

[0044] See the appendix Figure 1 - appendix Figure 4 , the volume of the scaffolding is often large and it is not convenient to carry and move. To solve the above problems, the following design is carried out in this embodiment. Specifically, the lower part 1 of the device further includes a plurality of pulleys 8. The plurality of pulleys 8 are all arranged at the bottom of the first weighing device 11, so that the scaffolding safety monitoring device can move under the rolling action of the plurality of pulleys 8.

[0045] Through the design of the above structure, the scaffolding safety monitoring device used in this construction can be conveniently moved under the rolling action of the pulleys 8; it should be noted that the specific parameters such as the quantity, position, and type of the pulleys 8 are not limited in this application and can be flexibly selected according to actual needs. For example, in this embodiment, four pulleys 8 arranged in a rectangular array can be selected, two of the pulleys 8 are directional wheels, and the other two pulleys 8 are directional wheels with brakes, so that the scaffolding safety monitoring device used in this construction is convenient to turn and fix.

[0046] See the appendix Figure 1 and the appendix Figure 6, situations such as some construction items being heavy or a large number of staff members can affect the upward shift of the center of gravity of the safety monitoring device for the scaffolding used in construction. If the items are removed from the scaffolding or the number of staff members is reduced, not only is the operation cumbersome, but it will also affect the work progress. To solve the above problems, the following design is carried out in this embodiment. Specifically, the lower part 1 of the device further includes a plurality of counterweight blocks 9, and the plurality of counterweight blocks 9 are all placed on the top of the first weighing device 11 to adjust the weight of the lower part 1 of the device so that the ratio of the numerator to the denominator is less than one-half.

[0047] Through the design of the above structure, when the center of gravity is relatively high, the weight of the lower part 1 of the device can be increased separately by increasing the number of counterweight blocks 9, so that the center of gravity moves downward, that is, the numerator remains unchanged and the denominator becomes larger. There is no need to remove the items on the top of the upper part 2 of the device or reduce the number of staff members, which is more convenient. It should be noted that the counterweight blocks 9 should be added within the load range of the safety monitoring device for the scaffolding used in this construction to prevent danger caused by overloading.
