Description

TECHNICAL FIELD

[0001] The utility model relates to scaffold deformation monitoring technical field, especially a kind of attached lifting scaffold main frame deformation monitoring device. BACKGROUND

[0002] As a new type of scaffold technology, attached lifting scaffold changes high-altitude work into low-altitude work and changes suspended work into internal work of frame body, and is widely used in high-rise and super high-rise building construction. The main frame, as a key part of the attached lifting scaffold, its stability is directly related to the construction safety of the entire scaffold. The application of the main frame deformation monitoring device can monitor the deformation of the main frame in real time, and once the deformation exceeds the safe range, an alarm is sent in time to provide evacuation time for construction personnel and avoid the occurrence of safety accidents, which is of great significance to ensure construction safety.

[0003] Patent No. CN216925448U discloses an attached scaffold deformation monitoring equipment, which comprises three groups of telescopic columns, springs, fixing rings, pressing switches and light emitting lamps. The telescopic columns contact the scaffold and compress the springs, and the pressing switches and light emitting lamps indicate the deformation of the scaffold to realize the monitoring of slight deformation.

[0004] However, this patent still has some defects in practical application. Specifically, such detection equipment relies on periodic manual inspection and cannot realize real-time and continuous monitoring, which is undoubtedly a major defect. In the process of building construction, the deformation of the scaffold main frame may be instantaneous, gradual or change at any time under complex working conditions. If only the light indication of the monitoring equipment is checked periodically by manual inspection, the critical moment of deformation may be easily missed, the dynamic change process of deformation cannot be grasped in time, and it is difficult to meet the urgent needs of real-time control of scaffold safety on the construction site.

[0005] The existing attached lifting scaffold main frame deformation monitoring device has obvious defects, especially the key problem that manual periodic inspection cannot realize real-time and continuous monitoring. With the continuous progress of building construction technology and the increasing requirements of safety production, there is an increasingly urgent need for a device that can accurately and real-time monitor the deformation of the scaffold. It is very important to develop a device with real-time data acquisition, transmission and analysis functions, which can continuously and uninterruptedly monitor the deformation of the main frame without human intervention, to improve the level of essential safety in building construction.

Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0042] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0043] Refer toFigure 1 The utility model provides a kind of attached lifting scaffold main frame deformation monitoring device, to realize the real-time monitoring of scaffold main frame deformation condition, and timely send alarm when deformation exceeds safe range, provide strong guarantee for construction safety.

[0044] Specific structure includes first base 1, ranging block 2, second base 3, multidirectional adjusting mechanism, ranging module 4, control module 5, background server 7 and power module 8.

[0045] Preferably, connecting hole 21 is arranged on first base 1, and connecting hole 21 on first base 1 is installed on attached lifting scaffold main frame by bolt, for example, is installed on step frame.First base 1 is installed with ranging block 2 on the side close to building, and ranging block 2 can be hemispherical or truncated conical, with convex end or tip towards second base 3.For example, with ranging block 2 being truncated conical, the top of the cone of ranging block 2 is provided with cross positioning mark 20, which is towards ranging module 4, providing clear aiming reference for ranging module 4.

[0046] Reference Figures 5-6 Connecting hole 21 is also arranged on second base 3, and connecting hole 21 on second base 3 is installed on the building that has been constructed by expansion bolt.Second base 3 is equipped with multidirectional adjusting mechanism.Multidirectional adjusting mechanism is composed of vertical adjusting assembly and horizontal adjusting assembly, which cooperate with each other, and can drive ranging module 4 to adjust position flexibly along vertical and horizontal directions.

[0047] Reference Figure 2 Ranging module 4 selects laser ranging sensor, ultrasonic ranging sensor or infrared ranging sensor, and is installed on multidirectional adjusting mechanism of second base 3.It is spaced and oppositely arranged with ranging block 2 installed on first base 1, for determining the distance between the two.

[0048] Ranging module 4 is electrically connected with control module 5, and control module 5 can select PLC equipment.Control module 5 is responsible for receiving distance information determined by ranging module 4, and comparing with initial distance to form distance change amount.Control module 5 pre-sets safety distance threshold value, when distance change amount calculated exceeds this threshold value, it is determined that scaffold main frame deforms and exceeds safe range.At this time, control module 5 immediately generates alarm information, and sends to background server 7 through wireless communication module 6 electrically connected therewith.After receiving alarm information, background server 7 can take corresponding measures in time, informs construction personnel to check and handle scaffold, to ensure construction safety.Power module 8 is electrically connected with control module 5, to provide stable power support for the whole monitoring device, to ensure that the device continues to operate normally.

[0049] Reference Figure 1、 Figure 3 and Figure 4 The vertical adjusting assembly comprises two support plates 9 fixedly connected to the second base 3 and arranged horizontally. The first screw rod 10 and the guide rod 11 are connected to the support plates 9 in a vertical manner. The lateral adjusting assembly is slidingly connected between the two support plates 9, and the distance measuring module 4 is mounted on the lateral adjusting assembly. The first screw rod 10 is threadedly connected to the lateral adjusting assembly, and the guide rod 11 is slidingly connected to the lateral adjusting assembly.

[0050] Specifically, the lateral adjusting assembly mainly comprises a sliding seat 12, a sliding rail 13, a sliding block 14 and a second screw rod 15. The sliding seat 12 is located between the two support plates 9, is threadedly connected to the first screw rod 10, and is slidingly connected to the guide rod 11. The sliding rail 13 parallel to the support plates 9 is arranged above the sliding seat 12. The sliding block 14 is slidingly connected to the sliding rail 13, and the distance measuring module 4 is mounted on the sliding block 14. The second screw rod 15 is rotationally connected to the sliding seat 12 and is threadedly connected to the sliding block 14. When the second screw rod 15 rotates, the sliding seat 12 can slide on the sliding rail 13, so that the distance measuring module 4 moves in the horizontal direction.

[0051] In order to realize smoother adjustment operation, the lateral adjusting assembly further comprises a second screw inclined gear 16 and a first screw inclined gear 17. The second screw rod 15 coaxially fixedly sleeves the second screw inclined gear 16. One end of the sliding seat 12 rotationally connects the first screw inclined gear 17, and the two gears are engaged. The first screw inclined gear 17 is slidingly sleeved on the side of the guide rod 11 and can synchronously rotate with the guide rod 11. One end of the first screw rod 10 and the guide rod 11 respectively penetrates one of the support plates 9 and is fixedly connected to the first knob 18 and the second knob 19, so as to facilitate the position adjustment of the operator.

[0052] Optionally, with reference to Figure 4 The first screw inclined gear 17 is coaxially fixedly connected with a gear sleeve. The outer side wall of the gear sleeve is rotationally connected to the sliding seat 12, so as to realize the rotationally connected effect of the first screw inclined gear 17 and one end of the sliding seat 12. The inner side wall of the gear sleeve is slidingly connected to the guide rod 11 and can synchronously rotate, so as to realize the synchronous rotation effect of the first screw inclined gear 17 and the guide rod 11.

[0053] In actual operation, if the vertical position of the distance measuring module 4 needs to be adjusted, the operator can rotate the first knob 18 to drive the first screw rod 10 to rotate. Since the sliding seat 12 is threadedly connected with the first screw rod 10, under the action of the thread, the sliding seat 12 moves vertically along the guide direction of the guide rod 11, so that the position adjustment of the distance measuring module 4 in the vertical direction is realized. For horizontal position adjustment, the second knob 19 is rotated to drive the second screw rod 15 to rotate, and then drive the sliding block 14 threadedly connected therewith to move along the sliding rail 13, so that the precise adjustment of the horizontal position of the distance measuring module 4 is completed. Through this flexible multi-directional adjustment mechanism, it can be ensured that the distance measuring module 4 is always accurately aligned with the distance measuring block 2, and the smooth progress of the distance measuring work is ensured.

[0054] In use, the first base 1 is installed on the main frame of the attached lifting scaffold, and the second base 3 is installed on the completed building or other fixed structure, so as to ensure that the main frame of the attached lifting scaffold does not move synchronously. By adjusting the first knob 18 and the second knob 19, the distance measuring module 4 is kept consistent with the center point of the cross positioning mark 20 on the distance measuring block 2. Taking the distance measuring block 2 as an example, the top radius of the truncated cone should be less than the set safety interval threshold value. When the displacement between the main frame of the attached lifting scaffold and the completed building is parallel to the second base 3, and the distance measuring module 4 is always opposite to the top of the distance measuring block 2, the distance measured by the distance measuring module 4 does not change in this process, and the deformation displacement of the main frame of the attached lifting scaffold belongs to the safety interval threshold value, and no alarm information is triggered. Similarly, when the displacement between the main frame of the attached lifting scaffold and the completed building is parallel to the second base 3, and the distance measuring module 4 is opposite to the conical surface of the distance measuring block 2, the actual distance change amount at this time is equal to the top radius of the cone + the measured distance change amount*cosα, and α is the slope of the conical surface. When the actual distance change amount is greater than the set safety interval threshold value, an alarm information is generated. Similarly, when the displacement between the main frame of the attached lifting scaffold and the completed building is perpendicular to the second base 3, and the distance change amount is greater than the set safety interval threshold value, an alarm information is generated. When the background server 7 receives the alarm information, personnel should go to the position where the alarm occurs for secondary confirmation, and judge the deformation direction of the main frame of the attached lifting scaffold by comparing the position relationship between the distance measuring module 4 and the cross positioning mark 20, and accordingly obtain the rectification measures.

[0055] It should be noted that when the displacement between the main frame of the attached lifting scaffold and the completed building is parallel and perpendicular to the second base 3 at the same time, there may be a case where the distance change amount is zero, and in this case, the alarm information may not be generated, and false alarm may occur. In view of this, the utility model should be provided with multiple monitoring devices in actual use, and distance measuring blocks 2 with different conical surface slopes can be installed to cope with the false alarm of a single monitoring device.

[0056] It can be understood that the above-mentioned distance change amount can be negative, and the absolute value of the distance change amount should be compared with the safety distance threshold when compared with the safety distance.

[0057] The embodiment has the following advantages:

[0058] Firstly, by setting the first base 1 and the second base 3 on the scaffold and the completed building respectively, and providing the distance measuring block 2 and the distance measuring module 4, the deformation of the scaffold main frame can be accurately determined, accurate monitoring is realized, and the dependence on manual periodic inspection is reduced. Secondly, the control module 5 can receive and analyze the distance measuring information in real time, and once the distance change amount exceeds the set safety distance threshold, an alarm information is generated and sent to the background server 7, so that the safety hidden danger can be found in time, and the occurrence of accidents such as scaffold collapse can be effectively prevented. Furthermore, the distance measuring module 4 adopts advanced distance measuring technologies such as laser, ultrasonic wave or infrared, has the advantages of high measuring accuracy, fast response speed and good stability, and is suitable for complex building construction environment. In addition, the multi-direction adjusting mechanism is designed ingeniously and is convenient to operate, and the position of the distance measuring module 4 can be flexibly adjusted, so that the distance measuring work can be smoothly carried out.

[0059] In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0060] The above-described embodiments are only preferred modes of the utility model, and do not limit the scope of the utility model, and various deformations and improvements of the technical scheme of the utility model made by those skilled in the art without departing from the design spirit of the utility model should fall within the protection scope of the utility model claim.
