Technical Field

[0001] This application relates to the technical field of detection equipment, and in particular to a verticality detection device for a construction elevator. Background Art

[0002] During the construction process, elevators are often used to transport building materials from low places to high places. Existing elevators generally include guide rails, drive mechanisms, and lifting platforms, etc. Among them, the guide rails are vertically installed on the ground. During use, it is necessary to measure the verticality of the guide rails. If the guide rails are inclined, it is easy to cause construction accidents and pose a great safety hazard. In the prior art, for the calibration and detection of guide rails, the common method is to use a plumb bob to detect the verticality, but the plumb bob detection is extremely susceptible to the external environment and is not intuitive enough. Therefore, a verticality detection device for a construction elevator is proposed. Utility Model Content

A detection mechanism is arranged on the upper surface of the guide rail. The detection mechanism includes a fixed plate and a movable plate. The fixed plate is fixedly installed on the wall surface through a connection mechanism. The movable plate is located above the fixed plate. An elastic mechanism is arranged between the movable plate and the fixed plate. A pressure sensor is arranged on the surface of the movable plate. Pulling ropes are fixedly connected to the four sides of the movable plate. The other ends of the pulling ropes are fixedly connected to the guide rail, and the pulling ropes are evenly distributed around the guide rail. Guide rings corresponding to the pulling ropes are fixedly connected to the four sides of the fixed plate, and the pulling ropes pass through the guide rings.

[0006] Preferably, the elastic mechanism includes a T-shaped rod inserted on the surface of the movable plate. The lower end of the T-shaped rod is fixedly connected to the fixed plate. A spring is sleeved on the surface of the T-shaped rod. One end of the spring is fixedly connected to the fixed plate, and the other end of the spring is fixedly connected to the movable plate.

[0007] Preferably, the connection mechanism includes a mounting plate. The mounting plate is fixedly connected to the fixed plate and is perpendicular to the fixed plate. Bolts are arranged at the four corners of the mounting plate to connect with the wall surface.

Detailed Description of the Invention

[0016] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0017] The embodiment of the present application discloses a verticality detection device for a construction hoist, including a guide rail 1 and a lifting platform 2. The lifting platform 2 is connected to the guide rail 1 through a lifting mechanism. A detection mechanism is arranged on the upper surface of the guide rail 1. The detection mechanism includes a fixing plate 7 and a movable plate 8. The fixing plate 7 is fixedly installed on the wall through a connecting mechanism. The movable plate 8 is located above the fixing plate 7. An elastic mechanism is arranged between the movable plate 8 and the fixing plate 7. A pressure sensor 15 is arranged on the surface of the movable plate 8. Pull ropes 9 are fixedly connected to the four sides of the movable plate 8. The other ends of the pull ropes 9 are fixedly connected to the guide rail 1. The pull ropes 9 are evenly distributed around the guide rail 1. Guide rings 10 corresponding to the pull ropes 9 are fixedly connected to the four sides of the fixing plate 7. The pull ropes 9 pass through the guide rings 10.

[0018] Further, the elastic mechanism includes a T-shaped rod 13 inserted on the surface of the movable plate 8. The lower end of the T-shaped rod 13 is fixedly connected to the fixed plate 7. A spring 14 is sleeved on the surface of the T-shaped rod 13. One end of the spring 14 is fixedly connected to the fixed plate 7, and the other end of the spring 14 is fixedly connected to the movable plate 8.

[0019] Further, the connecting mechanism includes a mounting plate 6. The mounting plate 6 is fixedly connected to the fixed plate 7 and is perpendicular to the fixed plate 7. Bolts 16 are provided at the four corners of the mounting plate 6 for connection to the wall surface.

[0020] Further, a slider 11 is fixedly connected to the surface of the movable plate 8, and a vertical groove 12 is formed on the surface of the mounting plate 6. The slider 11 is slidably installed inside the vertical groove 12.

[0021] In this embodiment, the mounting plate 6 is installed on the wall surface at the top of the guide rail 1 by using bolts 16, so that the fixed plate 7 and the movable plate 8 are located directly above the guide rail 1. When the guide rail 1 is perpendicular to the ground, the spring 14 between the fixed plate 7 and the movable plate 8 is in its original length, and the pressure detected by the pressure sensor 15 is zero. When the guide rail 1 tilts towards a certain side, the guide rail 1 will pull the pull rope 9 on that side, and the pull rope 9 will then pull the movable plate 8, causing the movable plate 8 to move downward. The movable plate 8 will thus compress the spring 14, causing the spring 14 to be compressed. At this time, the spring 14 exerts a force on the pressure sensor 15. After the pressure sensor 15 detects the pressure, it can transmit a signal to the background computer, which can remind the staff that the guide rail 1 is tilted and timely maintenance can be carried out to avoid accidents. By arranging pull ropes 9 around the guide rail 1, no matter which side the guide rail 1 tilts towards, it can drive the movable plate 8 to move, and the tilt of the guide rail 1 can be detected with good detection effect.

[0022] Further, the lifting mechanism includes a lead screw 4 rotatably installed inside the guide rail 1. A motor 5 is fixedly installed at the bottom of the guide rail 1, and the output shaft of the motor 5 is fixedly connected to the lead screw 4. A ball seat 3 is sleeved on the surface of the lead screw 4, and the ball seat 3 is fixedly connected to the lifting platform 2.

[0023] In this embodiment, by driving the motor 5 to drive the lead screw 4 to rotate, the ball seat 3 and the lifting platform 2 can be moved along the lead screw 4, and building materials can be transported from a low place to a high place.

[0024] It should be noted that: the switch interfaces of the motor 5 are all connected to an external power supply through wires. The circuits and related drive programs involved are all conventional existing technologies and will not be elaborated here.
