Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, specifically to a coupler-type intelligent monitoring device for scaffolding and its usage method. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] Existing coupler-type scaffolding has the following disadvantages when supporting concrete structural slabs: 1. Some monitoring devices use pressure sensors for monitoring, which need to be installed before erection and cannot be used in the scaffolding after it has been erected; 2. It cannot provide effective support and fixation after local foundation settlement below. Summary of the Invention

[0004] The purpose of this invention is to provide a smart monitoring device and method for using fastener-type scaffolding, in order to solve the problems of existing monitoring devices that rely on pressure sensors for monitoring, which need to be installed before erection and cannot be used in the scaffolding after it has been erected; and that they cannot provide effective support and fixation after local foundation settlement.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coupler-type intelligent monitoring device for scaffolding includes a scaffold and multiple guide components mounted on the scaffold. Support frames are provided on the outer sides of two guide components on the same side, and the length of the support frames is adjustable to clamp the guide components and limit the scaffold's position. Each guide component includes four limiting blocks on both sides of the support frame. A connecting block is provided at the top of each limiting block, and a lifting block is provided at the top of each connecting block. Adjacent limiting blocks, connecting blocks, and lifting blocks interlock to form a complete circular structure. Lifting mechanisms are provided on both sides of the support frame, and these mechanisms cooperate with the lifting blocks to lift the scaffold after it has sunk. A reinforcing mechanism is provided on each lifting block to limit the position of the lifted scaffold. An infrared transmitter is located inside each connecting block. A rectangular opening is provided on the outer side of the scaffold, and an infrared receiver, which works with the infrared transmitter, is located inside the rectangular opening for position monitoring of the scaffold. A base is provided at the bottom of the scaffold, and a damper is provided between the base and the scaffold for monitoring the scaffold's load-bearing capacity.

[0007] Furthermore, the support frame includes two connecting strips, each with a side strip at both ends. A sleeve rod is fixedly provided on the inner side of one of the connecting strips, and a screw is threaded into the sleeve rod. The other end of the screw is fixedly connected to the other connecting strip for adjusting the spacing between the two sets of side strips. A first guide rod is fixedly provided on one side of each of the two side strips on the same side. The first guide rod is inserted into the corresponding side strip for relative guidance.

[0008] Furthermore, the outer end of the edge strip is provided with an arc-shaped opening that matches the limiting block, and a pin is fixedly provided on the outer side of the limiting block. The arc-shaped opening is provided with a socket for inserting the pin, and the pin is inserted from top to bottom.

[0009] Furthermore, multiple insertion posts are fixedly provided on one side of both the lifting block and the limiting block, and corresponding insertion holes for insertion into the insertion posts are opened on the inner side of both the limiting block and the lifting block. A fixing seat is fixedly provided on the outer side of the connecting block, and a second guide rod is slidably provided through the top of the fixing seat. The lifting block is rotatably located inside the second guide rod.

[0010] Furthermore, the lifting mechanism includes a guide rail fixedly disposed on the outside of the side strip, and the same AGV trolley is disposed on multiple guide rails on the same side. An mounting plate is fixedly disposed on the top of the AGV trolley, and an electric push rod is fixedly disposed through the top of the mounting plate. A third guide rod is fixedly disposed on the top of the mounting plate, and a lifting plate that cooperates with the lifting block is slidably disposed on the outer wall of the third guide rod. The output end of the electric push rod is fixedly connected to the lifting plate.

[0011] Furthermore, a fixing strip is fixedly provided on one side of one of the lifting blocks, and an extension strip for use with the lifting plate is fixedly provided at the bottom of the fixing strip.

[0012] Furthermore, the reinforcement mechanism includes a support rod rotatably disposed within the fixed bar, an adjusting rod being provided internally by the support rod, a support block cooperating with the adjusting rod being fixed on one side of one of the connecting blocks, and a positioning groove cooperating with the lifting block being provided on the outer wall of the scaffold.

[0013] A method for using a coupler-type scaffolding intelligent monitoring device includes the following steps:

[0014] S1. First, move the corresponding limiting block to one end of the edge strip so that the pin is inserted into the corresponding socket. Place the support frame between two adjacent sets of scaffolding and fix the concrete structure slab above the scaffolding. Then, rotate the sleeve rod to drive the screw rod to move. The movement of the screw rod can drive the two sets of edge strips to move away from each other, causing the two corresponding limiting blocks to engage and insert the pin into the corresponding socket. This makes the lifting block, connecting block and limiting block form a complete circular structure, limiting the bottom of the scaffolding.

[0015] S2. Then, power on the AGV trolley, infrared transmitter, and infrared receiver. When the scaffolding settles below or the upper part of the scaffolding is subjected to heavy pressure on the damper for a long time, the scaffolding will move downward. During the movement, the infrared receiver receives the infrared light from the infrared transmitter and triggers an alarm through the external alarm. At the same time, the AGV trolley is started, which moves the lifting plate to the corresponding extension bar.

[0016] S3. Next, start the electric push rod extension. The extension of the electric push rod can drive the lifting plate to move upward. During the upward movement of the fixing bar, it can drive the lifting block to rotate on the second guide rod through the extension bar and the fixing bar until the inner wall of the lifting block abuts against the positioning groove. Continue to move upward, and the two lifting blocks can drive the scaffolding to be lifted upward. During the rotation and upward movement of the fixing bar, it can drive the support rod to move, and can drive the insertion hole to move onto the insertion column. Then start the electric push rod to retract, and the extension bar can move downward under gravity. At this time, the insertion hole can be locked in the positioning hole of the insertion column, limiting the lifting block, thereby temporarily lifting the scaffolding and keeping it stable.

[0017] S4. Finally, the scaffolding and the ground are reinforced manually. After the reinforcement is completed, the insertion hole is rotated so that it moves upward inside the support rod and disengages from the insertion column. Then, the lifting block is manually turned to reset it.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention enables the lifting block to rotate by activating the electric push rod. When the lifting block contacts the scaffold, it continues to move upward to lift the scaffold. During the reset process, the insertion hole contacts the insertion column, thereby limiting the lifting of the scaffold. This invention can temporarily limit and reinforce the scaffold, and can lift and adjust multiple scaffolds in sequence to maintain the stability of the scaffold.

[0020] 2. The present invention allows the length of the support frame to be adjusted by setting the sleeve rod and screw rod. During the adjustment process, it can drive the two corresponding limit blocks to move closer to each other to limit the bottom of the scaffold, which can ensure the stability of the bottom of the scaffold. It is also convenient to install on the erected scaffold, making the installation more flexible and the operation simple.

[0021] 3. This invention, through the combined use of an infrared transmitter, an infrared receiver, and a damper, enables the monitoring of the lifting position of the scaffolding, facilitating timely detection. Furthermore, upon detection, it can automatically activate the lifting mechanism for raising and reinforcing, thereby improving safety during use.

[0022] 4. This invention can monitor the raising and lowering of scaffolding through infrared transmitters and receivers. After detecting the raising and lowering, it can promptly activate the lifting mechanism to raise the lowered scaffolding, which can temporarily ensure the stability of the scaffolding, improve safety during use, and facilitate installation on the erected scaffolding, making it more flexible and convenient to use.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 This invention provides a coupler-type intelligent monitoring device for scaffolding, including a main structure for constructing scaffolding 1, and guide components 3 on the outer side of each of its support legs. An adjustable length support frame 2 is provided between two adjacent sets of guide components 3 for clamping the guide components 3 and limiting the scaffolding 1, and fixing the concrete structure slab 37 above the scaffolding 1.

[0034] The support frame 2 consists of two connecting strips 5. Each end of the connecting strip 5 is fixed with a side strip 6. A sleeve rod 8 is fixed on the inner side of one of the connecting strips 5. The sleeve rod 8 is connected to a screw rod 9 by a thread. The other end of the screw rod 9 is fixedly connected to the other connecting strip 5. By rotating the screw rod 9, the spacing between the two sets of side strips 6 can be adjusted to accommodate scaffolding 1 of different widths.

[0035] Each guide assembly 3 includes two limiting blocks 13, which are respectively set on both sides of the support frame 2. A connecting block 14 is provided on the top of the limiting block 13, and a lifting block 15 is provided on the top of the connecting block 14. The two adjacent limiting blocks 13, connecting blocks 14 and lifting blocks 15 are assembled by snap-fit ​​to form a complete circular structure to better wrap the uprights of the scaffold 1.

[0036] Multiple insertion posts 23 are fixedly provided on one side of both the lifting block 15 and the limiting block 13. Correspondingly, insertion holes 22 for insertion into the insertion posts 23 are opened on the inner side of the limiting block 13 and the lifting block 15 to achieve a stable connection between the two. A fixing seat 17 is fixedly provided on the outer side of the connecting block 14. A second guide rod 18 is slidably provided through the top of the fixing seat 17. The lifting block 15 is rotatably provided inside the second guide rod 18 to ensure that the lifting block 15 can move smoothly during the lifting process. A lifting mechanism 4 is provided on both sides of each support frame 2. The lifting mechanism 4 includes a guide rail 10 fixed on the outer side of the side strip 6. The same AGV trolley 25 is provided on multiple guide rails 10 on the same side. The AGV trolley 25 adopts the AGV trolley in patent document CN113023620B. An installation plate 26 is fixedly provided on the top of the AGV trolley 25. An electric push rod 27 is fixedly provided through the top of the installation plate 26. Meanwhile, a third guide rod 28 is fixedly installed on the top of the mounting plate 26. A lifting plate 29 that works with the lifting block 15 is slidably installed on the outer wall of the third guide rod 28. The output end of the electric push rod 27 is fixedly connected to the lifting plate 29. By controlling the extension and retraction of the electric push rod 27, the lifting plate 29 can be driven to move up and down, thereby lifting or lowering the lifting block 15, causing the lifting block 15 to rotate and contact the upright of the scaffold 1, and driving the scaffold 1 to move upward.

[0037] One of the lifting blocks 15 is fixedly provided with a fixing strip 19 on one side, and an extension strip 20 that works with the lifting plate 29 is fixedly provided at the bottom of the fixing strip 19 to ensure that the lifting plate 29 can accurately act on the lifting block 15, so that the extension strip 20 will not detach from the lifting plate 29 during the rotation of the lifting block 15.

[0038] An infrared transmitter 34 is installed inside each connecting block 14, and a rectangular opening 32 is opened on the outside of the upright of the scaffold 1. An infrared receiver 33 that works with the infrared transmitter 34 is installed inside the rectangular opening 32. This monitoring system can detect changes in the position of the scaffold 1 in real time and will immediately issue an alarm once abnormal movement is detected.

[0039] Meanwhile, a base 31 is installed at the bottom of the scaffold 1, and a damper 30 is installed between the base 31 and the scaffold 1. The damper 30 can support the load borne by the scaffold 1. When the load exceeds the preset threshold, the damper 30 is compressed, and the scaffold 1 moves downward. In conjunction with the infrared transmitter 34 and infrared receiver 33 monitoring, an alarm will also be issued to remind the operators to take timely measures to ensure construction safety.

[0040] Each of the two side strips 6 on the same side is fixedly provided with a first guide rod 7. The first guide rod 7 is inserted into the corresponding side strip 6 to ensure that the side strips 6 maintain relative guidance during the adjustment process and avoid misalignment.

[0041] The outer end of the edge strip 6 is provided with an arc-shaped opening 11 that matches the limiting block 13. A pin 16 is fixedly provided on the outer side of the limiting block 13. An insertion port 12 for inserting the pin 16 is provided on the inner side of the arc-shaped opening 11. The pin 16 is inserted into the insertion port 12 from top to bottom to ensure that the limiting block 13 is firmly fixed on the edge strip 6.

[0042] The reinforcement mechanism mainly includes a support rod 21 rotatably mounted within the fixed strip 19. The support rod 21 has an adjusting rod 35 threaded inside, which cooperates with a support block 36 fixed to one side of a connecting block 14. The top of the support block 36 has a groove. When the scaffold 1 is lifted to a predetermined position, the support rod 21 moves upward above the support block 36 and remains vertical. The electric push rod 27 is controlled to move the lifting plate 29 downward, so that the bottom end of the adjusting rod 35 is inserted into the groove on the support block 36. This allows the lifting block 15 to be clamped onto the scaffold 1, achieving a limiting and reinforcement effect on the scaffold 1 after lifting. In addition, the outer wall of the scaffold 1 also has a positioning groove 24 that cooperates with the lifting block 15 to ensure the accuracy of the lifting block 15 during the lifting and reinforcement process.
