Description

Technical Field

[0001] This utility model relates to the field of construction platform support technology, specifically a construction platform support with offset detection function. Background Technology

[0002] Construction platform scaffolding is a commonly used temporary support structure in construction, decoration, and bridge construction projects. It primarily provides a safe working platform for workers, supports formwork, or carries construction materials. The structure of a construction platform scaffolding mainly consists of uprights, horizontal bars, diagonal braces, connectors, and a working platform: the uprights serve as the vertical load-bearing structure, the horizontal bars connect to form a frame, the diagonal braces enhance the overall lateral stability, the connectors fix the nodes through plugs or fasteners, and the steel or wooden plates laid on top form the working platform. All components work together to form a temporary support system capable of supporting personnel, materials, and construction loads.

[0003] Utility model patent CN216766714U discloses a freely detachable construction platform support, which comprises a front upright, diagonal brace, platform pole, rear upright, support connecting plate, platform pole reinforcing rib, platform footboard, kick connecting plate, and connecting sleeve. All components are fully welded together. In use, this patented product is bolted to the attachment through the support connecting plate. This utility model aims to provide a freely detachable construction platform support, which has the advantages of convenient installation and use, assemblability, reusability, high reusability, safety, practicality, and aesthetics, resulting in significant economic and social benefits.

[0004] The aforementioned platform support needs to be fixed to the existing structural surface during use. Over a long period of use, the platform support is prone to loosening due to vibration, causing the entire platform support to shift. Since the aforementioned platform support lacks detection and early warning measures for shift, it cannot attract the attention of maintenance personnel when a slight shift occurs, and it cannot serve as a reminder for maintenance. Furthermore, it does not provide an alarm function when the shift exceeds the safety threshold, making it impossible for workers on it to evacuate in time, which may cause serious safety consequences. Therefore, in order to address the above problems, a construction platform support with shift detection function is proposed. Summary of the Invention

[0005] The technical problem this utility model aims to solve is to provide a construction platform support with offset detection function. This support is composed of several arranged support units, each equipped with an alarm. A displacement detection and early warning mechanism connects the support unit to the structural surface it is mounted on. When the support unit shifts due to loose connections, it pulls a sliding transmission component along a guide rod, allowing the displacement sensing mechanism to detect the displacement change and assist maintenance personnel in determining the looseness of the connection. Furthermore, when the displacement of the support unit suddenly changes and reaches a safety threshold, the alarm contact mechanism is activated, connecting the alarm's circuit. The alarm then alerts workers on the support to evacuate immediately to avoid serious accidents. This solves the technical problem of comparative technologies lacking detection and early warning measures for support offset, failing to provide maintenance reminders for minor offsets, and failing to provide an alarm when the offset exceeds the safety threshold, potentially leading to serious accidents.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A construction platform support with offset detection function includes a support unit frame arranged in an array, on which a platform plate is laid; an alarm installed on the support unit frame; and a displacement detection and early warning mechanism connected to the support unit frame and the structural surface on which it is installed. During operation, the mechanism monitors the offset of the support unit frame relative to the structural surface and activates the alarm when the offset reaches a threshold. The displacement detection and early warning mechanism includes a guide rod and a sliding transmission component slidably connected thereto. The guide rod is mounted on the structural surface, and the sliding transmission component is mounted on the support unit frame. A displacement sensing mechanism is installed at the end of the guide rod. Furthermore, the displacement detection and early warning mechanism includes an alarm contact mechanism connected in series in the alarm's operating circuit. When the support unit frame shifts due to loose connections, it pulls the sliding transmission component along the guide rod, allowing the displacement sensing mechanism to detect the displacement change and assist maintenance personnel in determining the looseness of the connection. Additionally, when the displacement of the support unit frame suddenly changes and reaches a safety threshold, the alarm contact mechanism is activated, connecting the alarm's operating circuit. At this time, the alarm alerts workers on the support to evacuate immediately.

[0007] In one possible implementation, the guide rod includes a mounting plate with a hinge seat on which a rotatably connected guide rod is mounted. The structure allows the guide rod to rotate about the hinge seat as an axis, so that when the support unit frame shifts, it can maintain an effective connection with the sliding transmission component through rotation.

[0008] In one possible implementation, the sliding transmission component includes a mounting bracket with a shaft cylinder fixedly mounted at its bottom end. A rotatably connected sliding sleeve is installed in the shaft cylinder, and the sliding sleeve is slidably mounted on the guide rod. This structure allows the shaft cylinder to rotate freely, ensuring that when the support unit frame shifts, it can maintain an effective connection with the guide rod through rotation.

[0009] In one possible implementation, the displacement sensing mechanism includes an end plate fixedly mounted at the end of the guide rod, on which an annular pressure sensor is fixedly mounted by a fixing plate, and the annular pressure sensor does not contact the guide rod. The above structure can achieve the fixed installation of the annular pressure sensor and can ensure that the shaft and the annular pressure sensor are independent of each other, providing the necessary structural basis for measuring the offset.

[0010] In one possible implementation, a compression spring is fixedly connected to the end of the shaft cylinder, and a pressure ring is fixedly connected to the end of the compression spring. The position of the compression spring corresponds to the working part of the annular pressure sensor. When the shaft cylinder slides on the guide rod due to the offset of the support unit frame, it will apply pressure to the annular pressure sensor through the compression spring and the pressure ring. The greater the offset, the greater the pressure applied to the annular pressure sensor by the compression spring, so that the offset can be proportional to the pressure value measured by the annular pressure sensor, thereby determining the current offset of the support unit frame.

[0011] In one possible implementation, the alarm contact mechanism includes a moving contact and a stationary contact. The moving contact is fixedly connected to the shaft cylinder via an insulating cylinder, which is sleeved outside the guide rod but does not contact it. The stationary contact is fixedly mounted on the end plate. When the moving and stationary contacts are in contact, the alarm circuit is turned on. When the moving and stationary contacts are separated, the alarm circuit is turned off. When the offset of the support unit frame reaches a safety threshold, the moving contact on the insulating cylinder contacts the stationary contact, at which point the alarm circuit is turned on and operates, thus providing an alarm function.

[0012] In one possible implementation, the support unit frame includes a vertical connecting rod, with a platform support rod fixedly connected to its top. A vertical stop bar is fixedly connected to the outer end of the platform support rod. A strut is fixedly connected between the vertical connecting rod and the platform support rod. This structural form ensures that the support unit frame has a stable structure, maintains stability during use, and has a strong load-bearing capacity.

[0013] In one possible implementation, a plurality of first positioning hoops are fixedly installed on the vertical connecting rod, through which a connecting rod passes; a plurality of second positioning hoops are fixedly installed on the vertical stop bar, through which a railing passes. In the above structure, the connecting rod and the railing are used to connect all the support unit frames to form a whole, which has strong structural rigidity. At the same time, the railing can also serve as a protective structure to prevent workers from falling.

[0014] In summary, this utility model has the following beneficial technical effects: The construction platform support is composed of several rows of support units, on which an alarm is installed. A displacement detection and early warning mechanism is connected between the support unit frame and the structural surface on which it is installed. When the support unit frame shifts due to loose connecting parts, it will pull the sliding transmission component to slide along the guide rod, so that the displacement sensing mechanism can detect the displacement change and thus help maintenance personnel judge the looseness of the connection. In addition, when the displacement of the support unit suddenly changes and reaches the safety threshold, the alarm contact mechanism will be activated, connecting the working circuit of the alarm. At this time, the alarm will remind the workers on the support to evacuate in time to avoid serious accidents. Attached Figure Description

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2As shown, this embodiment provides a construction platform support with offset detection function, including a support unit frame 1 arranged in an array, on which a platform plate 2 is laid, an alarm 4 installed on the support unit frame 1, and a displacement detection and early warning mechanism 3, which connects the support unit frame 1 and the structural surface on which it is installed. During operation, it monitors the offset of the support unit frame 1 relative to the structural surface and triggers the alarm 4 when the offset reaches a threshold. The displacement detection and early warning mechanism 3 includes a guide rod 31 and a sliding transmission member 32 slidably connected thereto. The guide rod 31 is mounted on the structural surface, and the sliding transmission member 32 is installed on the support unit frame 1. The end of the guide rod 31... The displacement sensing mechanism 33 is installed. In addition, the displacement detection and early warning mechanism 3 also includes an alarm contact mechanism 34 connected in series in the working circuit of the alarm 4. When the support unit frame 1 shifts due to loose connecting parts, it will pull the sliding transmission part 32 to slide along the guide rod 31, so that the displacement sensing mechanism 33 can detect the displacement change, thereby assisting maintenance personnel in judging the looseness of the connection. In addition, when the displacement change of the support unit frame 1 suddenly changes and reaches the safety threshold, the alarm contact mechanism 34 will be in the working state, connecting the working circuit of the alarm 4. At this time, the alarm 4 will work to remind the personnel working on the support to evacuate in time.

[0018] The guide rod 31 includes a mounting plate 311 on which a hinge seat 312 is provided. A rotatably connected guide rod 313 is mounted on the hinge seat 312. This structure allows the guide rod 313 to rotate about the hinge seat 312. When the support unit frame 1 shifts, it can maintain an effective connection with the sliding transmission member 32 through rotation. Figure 3 As shown.

[0019] The sliding transmission component 32 includes a mounting bracket 321, the bottom of which is fixedly provided with a shaft cylinder 322. A rotatably connected sliding sleeve 323 is installed in the shaft cylinder 322. The sliding sleeve 323 is slidably sleeved on the guide rod 313. This structure allows the shaft cylinder 322 to have the characteristic of free rotation, ensuring that when the support unit frame 1 shifts, it can maintain an effective connection with the guide rod 313 through rotation. Figure 3 As shown.

[0020] The displacement sensing mechanism 33 includes an end plate 331 fixedly mounted at the end of the guide rod 313. An annular pressure sensor 333 is fixedly mounted on the end plate 331 via a fixing piece 332. The annular pressure sensor 333 does not contact the guide rod 313. This structure enables the fixed mounting of the annular pressure sensor 333 and ensures that the shaft cylinder 322 and the annular pressure sensor 333 are independent of each other, providing the necessary structural foundation for measuring the offset. Figure 3As shown; to cooperate with the operation of the annular pressure sensor 333, a compression spring 324 is fixedly connected to the end of the shaft cylinder 322, and a pressure ring 325 is fixedly connected to the end of the compression spring 324. Their positions correspond to the working part of the annular pressure sensor 333. When the shaft cylinder 322 slides on the guide rod 313 due to the offset of the support unit frame 1, it applies pressure to the annular pressure sensor 333 through the compression spring 324 and the pressure ring 325. The greater the offset, the greater the pressure applied to the annular pressure sensor 333 by the compression spring 324, so that the offset is proportional to the pressure value measured by the annular pressure sensor 333. This allows the determination of the current offset of the support unit frame 1. Figure 3 As shown.

[0021] The alarm contact mechanism 34 includes a movable contact 342 and a stationary contact 343. The movable contact 342 is fixedly connected to the shaft cylinder 322 via an insulating cylinder 341. The insulating cylinder 341 is sleeved around the guide rod 313 but does not contact it. The stationary contact 343 is fixedly mounted on the end plate 331. When the movable contact 342 and the stationary contact 343 are in contact, the alarm 4's working circuit is turned on. When the movable contact 342 and the stationary contact 343 are separated, the alarm 4's working circuit is turned off. When the offset of the support unit frame 1 reaches the safety threshold, the movable contact 342 on the insulating cylinder 341 contacts the stationary contact 343. At this time, the alarm 4's working circuit is turned on and operates, serving as an alarm. Figure 3 As shown.

[0022] like Figure 4 As shown, the support unit frame 1 includes a vertical connecting rod 11, with a platform support rod 12 fixedly connected to its top. A vertical stop rod 13 is fixedly connected to the outer end of the platform support rod 12. A strut 14 is fixedly connected between the vertical connecting rod 11 and the platform support rod 12. The above structure can ensure that the support unit frame 1 has a stable structure and can maintain stability and have a strong load-bearing capacity during use.

[0023] In addition, several first positioning clamps 15 are fixedly installed on the vertical connecting rod 11, through which connecting rods 5 are inserted; several second positioning clamps 16 are fixedly installed on the vertical stop rod 13, through which railings 6 are inserted. In the above structure, the connecting rods 5 and railings 6 are used to connect all the support unit frames 1 to form a whole, which has strong structural rigidity. At the same time, the railings 6 can also serve as a protective structure to prevent workers from falling. Figure 1 As shown.

[0024] The working principle and usage process of this utility model: The construction platform support consists of several rows of support unit frames 1, on which an alarm 4 is installed. A displacement detection and early warning mechanism 3 is connected between the support unit frame 1 and the structural surface on which it is installed. When the support unit frame 1 shifts due to loose connecting parts, it will pull the sliding transmission component 32 to slide along the guide rod 31, so that the displacement sensing mechanism 33 can detect the displacement change and thus assist maintenance personnel in judging the looseness of the connection.

[0025] When the shaft cylinder 322 slides on the guide rod 313 due to the offset of the support unit frame 1, it will apply pressure to the annular pressure sensor 333 through the compression spring 324 and the pressure ring 325. The greater the offset, the greater the pressure applied by the compression spring 324 to the annular pressure sensor 333, so that the offset can be proportional to the pressure value measured by the annular pressure sensor 333, thereby determining the current offset of the support unit frame 1.

[0026] Furthermore, when the displacement of the support unit frame 1 suddenly changes and reaches the safety threshold, the alarm contact mechanism 34 will be in the working state, connecting the working circuit of the alarm 4. At this time, the alarm 4 will work to remind the personnel working on the support to evacuate in time to avoid serious accidents. The alarm contact mechanism 34 includes a moving contact 342 and a stationary contact 343. The moving contact 342 is fixedly connected to the shaft cylinder 322 through an insulating cylinder 341. The insulating cylinder 341 is sleeved outside the guide rod 313 but does not contact it. The stationary contact 343 is fixedly installed on the end plate 331. When the moving contact 342 and the stationary contact 343 are in contact, the working circuit of the alarm 4 is connected. When the moving contact 342 and the stationary contact 343 are separated, the working circuit of the alarm 4 is disconnected. When the offset of the support unit frame 1 reaches the safety threshold, the moving contact 342 on the insulating cylinder 341 contacts the stationary contact 343. At this time, the working circuit of the alarm 4 is connected and works, playing an alarm role.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
