Description

Technical Field

[0001] This utility model relates to the field of engineering safety technology, specifically to a deformation monitoring device for a basket-type cantilever scaffold. Background Art

[0002] Basket-type cantilever scaffolding is a new type of external scaffolding system, mainly composed of transverse steel beams and basket-type tie rods. Deformation monitoring of basket-type cantilever scaffolding is one of the important measures to ensure construction safety. By regularly monitoring basket-type cantilever scaffolding, potential hazards can be detected in time, providing a basis for construction safety management and ensuring the smooth progress of the project. At the same time, it is necessary to analyze the monitoring data to understand the deformation trend of basket-type cantilever scaffolding.

[0003] Currently, when monitoring the deformation of basket-type cantilever scaffolding, the commonly used monitoring tools include theodolites, levels, etc., or visual observation. When using tools for monitoring, multiple construction workers need to coordinate their work, and the tools are relatively complicated to use. When using the naked eye, the monitoring results are not intuitive enough.

[0004] Therefore, it is of great importance to design a basket-type cantilever scaffold deformation monitoring device to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a deformation monitoring device for basket-type cantilever scaffolding. This device aims to solve the technical problems of existing technologies requiring multiple construction workers to coordinate their work, having complex tools, and providing insufficiently intuitive monitoring results when monitoring the deformation of basket-type cantilever scaffolding.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A deformation monitoring device for a basket-type cantilever scaffold includes a basket-type cantilever scaffold body fixedly installed on the outside of a building. Mounting frames are fixedly installed on both the left and right ends of the front of the building and at the bottom of the basket-type cantilever scaffold body. Sliding rods are fixedly installed on the top of each of the two mounting frames. Positioning frames are movably installed on the outer sides of the two sliding rods. A normally open photoelectric sensor signal transmitter is fixedly installed at the front end of each positioning frame. A normally open photoelectric sensor signal receiver is fixedly installed at the rear end of each mounting frame at a position corresponding to the normally open photoelectric sensor signal transmitter. An audible and visual alarm is fixedly installed on the left side of each positioning frame.

[0008] As a preferred embodiment of this utility model, the rear end of the mounting frame is fixedly installed on the outside of the building by mounting bolts, a pointer is fixedly installed on the back of the bottom end of the positioning frame, and a scale line is provided at the position of the rear end of the mounting frame corresponding to the pointer.

[0009] As a preferred embodiment of this utility model, both ends of the slide rod are fixedly connected to fixed feet, and both sets of fixed feet are fixedly connected to the mounting bracket by fixing bolts.

[0010] As a preferred embodiment of this utility model, positioning edges are fixedly connected to both the left and right sides of the front end of the positioning frame, and rubber protective pads are fixedly connected to the top of the positioning frame and the inner side of the positioning edges.

[0011] As a preferred embodiment of this utility model, the bottom of the positioning frame is rotatably connected to both the front and rear ends of the bottom, and the bottom ends of the two sets of transmission rods are rotatably connected to sliding sleeves, and the sliding sleeves are slidably connected to the sliding rods. Springs are sleeved on the outer side of the sliding rods and on the side opposite to the two sets of sliding sleeves.

[0012] As a preferred embodiment of this utility model, a connecting sleeve is fixedly connected to the outer side of the slide rod and below the positioning frame, and a rubber buffer pad is fixedly connected to the top of the connecting sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this utility model, through the coordinated design of the mounting frame, positioning frame, normally open photoelectric sensor signal transmitter, normally open photoelectric sensor signal receiver, and audible and visual alarm, when the basket-type cantilever scaffold body deforms, causing the positioning frame to tilt, the normally open photoelectric sensor signal transmitter will also tilt, and the normally open photoelectric sensor signal receiver will not receive a signal, directly activating the audible and visual alarm. At the same time, the tilting of the positioning frame will cause the pointer to swing, and the specific deformation intensity can be observed according to the position of the pointer pointing to the scale line.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-3 , the utility model provides a technical solution:

[0024] A basket-type cantilever scaffold deformation monitoring device includes a basket-type cantilever scaffold body 2 fixedly installed on the outside of a building 1. Mounting frames 3 are fixedly installed on both the left and right ends of the front of the building 1 and at the bottom of the basket-type cantilever scaffold body 2. Sliding rods 4 are fixedly installed on the top of the two sets of mounting frames 3. Positioning frames 5 are movably installed on the outside of the two sets of sliding rods 4. A normally open photoelectric sensor signal transmitter 6 is fixedly installed at the front end of the positioning frame 5. A normally open photoelectric sensor signal receiver 7 is fixedly installed at the rear end of the mounting frame 3 at a position corresponding to the normally open photoelectric sensor signal transmitter 6. An audible and visual alarm 8 is fixedly installed on the left side of the positioning frame 5.

[0025] First, the rear end of the mounting frame 3 is fixedly installed on the outside of the building 1 by mounting bolts 301. A pointer 302 is fixedly installed on the back of the bottom end of the positioning frame 5. A scale line 303 is provided at the position of the rear end of the mounting frame 3 corresponding to the pointer 302. The mounting frame 3 is installed and fixed on the outside of the building 1 by mounting bolts 301 and located below the basket-type cantilever scaffold body 2. After the mounting frame 3 is installed, the positioning frame 5 abuts against the left and right ends of the bottom of the basket-type cantilever scaffold body 2. When the connection between the basket-type cantilever scaffold body 2 and the building 1 deforms, the positioning frame 5 tilts accordingly, causing the pointer 302 to swing. The specific deformation intensity can be observed according to the position of the pointer 302 pointing to the scale line 303.

[0026] Furthermore, both ends of the slide rod 4 are fixedly connected with fixed feet 401. Both sets of fixed feet 401 are fixedly connected to the mounting frame 3 by fixing bolts 402. The fixed feet 401 are installed on the mounting frame 3 by fixing bolts 402, thereby installing the slide rod 4 on the mounting frame 3, making the whole device easy to assemble and disassemble.

[0027] Then, positioning edges 501 are fixedly connected to the left and right sides of the front end of the positioning frame 5, and rubber protective pads 502 are fixedly connected to the top of the positioning frame 5 and the inner side of the positioning edges 501. When installing the mounting frame 3, the positioning edges 501 are first clipped onto the left and right sides of the basket-type cantilever scaffold body 2, so that the top of the positioning frame 5 fits against the top of the basket-type cantilever scaffold body 2 for easy and quick installation and positioning. Then the mounting frame 3 is installed and fixed. At the same time, after the positioning frame 5 abuts against the bottom of the basket-type cantilever scaffold body 2, the rubber protective pads 502 protect the positioning frame 5 and the basket-type cantilever scaffold body 2 to avoid wear on the bottom of the basket-type cantilever scaffold body 2.

[0028] Furthermore, both the front and rear ends of the bottom of the positioning frame 5 are rotatably connected to transmission rods 503. The bottom ends of the two sets of transmission rods 503 are rotatably connected to sliding sleeves 504, and the sliding sleeves 504 are slidably connected to the sliding rods 4. Springs 505 are sleeved on the outer side of the sliding rods 4 and on the opposite side of the two sets of sliding sleeves 504. After the mounting frame 3 is installed and fixed, and the positioning frame 5 is in contact with the bottom end of the basket-type cantilever scaffold body 2, when the basket-type cantilever scaffold body 2 deforms, the positioning frame 5 tilts and pushes the sliding sleeves 504 on the outer side of the sliding rods 4 under the transmission of the transmission rods 503. This causes the sliding sleeves 504 to push the springs 505 to compress, thereby applying an upward force to the positioning frame 5. When the basket-type cantilever scaffold body 2 deforms, it can strengthen its bottom end, allowing construction workers to respond in time and further improving the safety of the device.

[0029] Secondly, a connecting sleeve 506 is fixedly connected to the outside of the slide rod 4 and below the positioning frame 5. A rubber buffer pad 507 is fixedly connected to the top of the connecting sleeve 506. When the basket-type cantilever scaffold body 2 is severely deformed, the positioning frame 5 will be pressed down and buffered by the rubber buffer pad 507 to avoid directly bending the slide rod 4 and ensure that the sliding sleeve 504 can slide normally outside the spring 505 to buffer the downward pressure.

[0030] Finally, the normally open photoelectric sensor signal transmitter 6 and the normally open photoelectric sensor signal receiver 7 are on the same horizontal line. A through hole 601 is provided inside the positioning frame 5 between the normally open photoelectric sensor signal transmitter 6 and the normally open photoelectric sensor signal receiver 7. The normally open photoelectric sensor signal receiver 7 is electrically connected to the audible and visual alarm 8. When the basket-type cantilever scaffold body 2 is in normal use, the laser emitted by the normally open photoelectric sensor signal transmitter 6 passes through the through hole 601 normally, so that the normally open photoelectric sensor signal receiver 7 receives the signal. At this time, the audible and visual alarm 8 is in the off state. However, as the basket-type cantilever scaffold body 2 deforms and the positioning frame 5 tilts, the normally open photoelectric sensor signal transmitter 6 tilts accordingly. The normally open photoelectric sensor signal receiver 7 cannot receive the signal and directly activates the audible and visual alarm 8 to sound and light alarm. This not only has a simple structure and a fast response, but also provides a more intuitive warning to construction workers.

[0031] In this embodiment, the specific implementation scenario is as follows: When installing the mounting frame 3, the positioning edge 501 is first clipped onto the left and right sides of the basket-type cantilever scaffold body 2, so that the top of the positioning frame 5 is in close contact with the top of the basket-type cantilever scaffold body 2 for convenient and quick installation and positioning. Then, the mounting frame 3 is installed and fixed. After the mounting frame 3 is installed and fixed, and the positioning frame 5 is in close contact with the bottom end of the basket-type cantilever scaffold body 2, when the basket-type cantilever scaffold body 2 deforms, the positioning frame 5 tilts and pushes the sliding sleeve 504 on the outside of the sliding rod 4 under the transmission of the transmission rod 503, so that the sliding sleeve 504 pushes the spring 505 to compress, thereby applying an upward force to the positioning frame 5. When the basket-type cantilever scaffold body 2 deforms, it can strengthen its bottom end to a certain extent. This invention enables construction workers to respond promptly. When the deformation of the basket-type cantilever scaffold body 2 causes the positioning frame 5 to tilt, the normally open photoelectric sensor signal transmitter 6 tilts accordingly. The normally open photoelectric sensor signal receiver 7 cannot receive the signal and directly activates the audible and visual alarm 8. At the same time, the tilting of the positioning frame 5 causes the pointer 302 to swing. The specific deformation intensity can be observed based on the position of the pointer 302 pointing to the scale line 303. The entire operation process is simple and convenient. Compared with the existing basket-type cantilever scaffold deformation monitoring methods, this utility model not only has a simple structure and rapid response, but also provides a more intuitive warning to construction workers, enabling them to respond promptly and further improving the safety of the device.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
