Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a lifting operation platform that can automatically position itself to the working height. Background Technology

[0002] Lifting work platforms are used in exterior wall construction, interior decoration, equipment installation and maintenance scenarios. In exterior wall construction (which includes foundation treatment, waterproofing, insulation and decoration, and interior wall construction includes foundation treatment, plastering and decoration), each construction step involves changes in wall thickness. Construction workers need to rise to the unworked position (working height) for each construction step. Existing technologies use laser sensors, ultrasonic sensors or encoders to monitor the platform's position and height in real time. However, this method can only reach a preset height and cannot automatically rise to the unworked position according to the actual construction situation. Utility Model Content

[0003] This application provides a lifting work platform that can automatically position itself to the working height, thus solving the technical problem in the prior art that it cannot automatically rise to an unworked position according to the actual construction situation.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a lifting work platform that can automatically position itself to the working height, comprising:

[0006] The platform has a lifting drive system installed at its lower end;

[0007] A guardrail is installed on the upper surface of the platform, and the upper surface of the guardrail is the mounting surface;

[0008] An unconstructed testing component includes a rotating cylinder that can rotate 180° relative to the mounting surface. A telescopic rod is elastically installed inside the rotating cylinder. One end of the telescopic rod passes through the rotating cylinder and is fixed to a bracket. A pressure roller is rotatably installed inside the bracket via a rotating shaft. A piston plate is fixed to the other end of the telescopic rod and is slidably connected to the rotating cylinder. A distance sensor is fixedly installed on the side of the piston plate away from the telescopic rod, and the distance sensor is electrically connected to a control component.

[0009] Furthermore, two mounting plates are fixed at the upper end of the mounting surface, and a fixed shaft is fixed between the two mounting plates. A sleeve is movably sleeved on the fixed shaft, and the sleeve is fixedly connected to the rotating cylinder.

[0010] Furthermore, the fixed shaft is fitted with a spring, and the two ends of the spring are fixed to the sleeve and the mounting plate respectively. The outer circumferential surface of the sleeve is fixed with a lug, and the side of the lug closest to the mounting plate is fixed with a pin. The mounting plate has two slots on the side near the pin, and the axes of the two slots are on the same horizontal plane.

[0011] Furthermore, two limiting plates are fixed on the side of the mounting plate near the pin, and when the rotating cylinder contacts either limiting plate, the pin corresponds to one of the slots.

[0012] Furthermore, the rotating shaft is rotatably connected to the bracket, one end of the rotating shaft passes through the bracket and is fixed with an encoder, and the encoder is signal-connected to the control component.

[0013] Furthermore, a second spring is fixed to the side of the piston plate away from the telescopic rod; one end of the second spring 316 is connected to the piston plate 315, and the other end is fixed to the inner wall of the rotating cylinder, and the distance sensor is located inside the second spring.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] This lifting platform is equipped with an in-construction detection component. Before each platform rises, the rotating cylinder is in a horizontal position and the pressure roller is in contact with the wall. The pressure roller is kept in contact with the wall by the elastic force of spring two. When the pressure roller rises to the in-construction position before the platform due to the height difference between the pressure roller and the platform, the pressure roller is displaced by contact with the in-construction position of the wall under the elastic force of spring two. After the distance sensor monitors this displacement change for 2 seconds, it controls the lifting drive system to stop rising and automatically rises to the working height.

[0021] To address the issue that existing technologies, such as laser sensors, ultrasonic sensors, or encoders, can only monitor the platform's position and height in real time, but cannot automatically rise to an unworked position based on actual construction conditions, this lifting platform is equipped with an unworked detection component 3. Before each ascent of the platform 1, the rotating cylinder 39 is horizontal, and the pressure roller 312 is in contact with the wall surface, including both inner and outer walls. The pressure roller 312 remains in contact with the wall surface under the elastic force of the second spring 316. When the pressure roller 312 rises to the unworked position before the platform 1 due to the height difference, it is displaced by contacting the unworked position on the wall surface under the elastic force of the second spring 316. After the distance sensor 317 monitors this displacement change for 2 seconds, it controls the lifting drive system to stop rising and automatically rises to the working height.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example: Refer to Figures 1 to 3 A lifting work platform that can automatically position itself to the working height includes a platform 1, a lifting drive system located at the lower end of the platform 1, a guardrail 2, and an unconstructed detection component 3. The lifting drive system adopts a hydraulic / electric / pneumatic drive system commonly used in the prior art. Through the cooperation of the platform 1, the guardrail 2, and the unconstructed detection component 3, the platform 1 can monitor the construction thickness difference of the wall surface in real time during its ascent and automatically stop rising when the platform 1 reaches the working height so that construction can continue.

[0024] Among them, the guardrail 2 is installed on the upper surface of the platform 1, and the upper surface of the guardrail 2 is the mounting surface 21; the unconstructed inspection component 3 includes a rotating cylinder 39 that can rotate 180 degrees relative to the mounting surface 21. Two mounting plates 31 are fixed at the upper end of the mounting surface 21, and a fixed shaft 32 is fixed between the two mounting plates 31. A sleeve 34 is movably sleeved on the fixed shaft 32, and the sleeve 34 is fixedly connected to the rotating cylinder 39. The rotating cylinder 39 rotates relative to the fixed shaft 32 through the sleeve 34.

[0025] Furthermore, to ensure the rotating cylinder 39 is stably fixed in two horizontal positions at 180°, a spring 33 is fitted around the fixed shaft 32. The two ends of the spring 33 are fixed to the sleeve 34 and the mounting plate 31, respectively. A lug 35 is fixed to the outer circumference of the sleeve 34, and a pin 36 is fixed to the side of the lug 35 closest to the mounting plate 31. Two slots 37 are formed on the side of the mounting plate 31 near the pin 36, with the axes of the two slots 37 on the same horizontal plane. The rotating cylinder 39 moves the sleeve 34 towards compressing the spring 33, causing the pin 36 to be pulled out of the slot 37 while maintaining the compression of the spring 33. After rotating the sleeve 34 180 degrees, the pin 36 aligns with the other slot 37, and the spring 33 is released, allowing the pin 36 to engage in the other slot 37. After reaching a suitable height, the sleeve 34 is operated to compress the spring 33, causing the pin 36 to engage in the inner slot 37.

[0026] To ensure the proper rotation position of the rotating cylinder 39, two limiting plates 38 are fixed on the side of the mounting plate 31 near the pin, eliminating the need for manual positioning. When the rotating cylinder 39 contacts either limiting plate 38, the pin 36 corresponds to one of the slots 37.

[0027] A second spring 316 is fixed to the side of the piston plate 315 away from the telescopic rod 314. One end of the second spring 316 is connected to the piston plate 315, and the other end is fixed to the inner wall of the rotating cylinder 39. One end of the telescopic rod 314 passes through the rotating cylinder 39, and a bracket 310 is fixed to one end of the telescopic rod 314. A pressure roller 312 is rotatably installed in the bracket 310 through a rotating shaft 311. The other end of the telescopic rod 314 is fixed to the piston plate 315, and the piston plate 315 is slidably connected to the rotating cylinder 39. A distance sensor 317 is fixedly installed on the side of the piston plate 315 away from the telescopic rod 314. The distance sensor 317 is located inside the second spring 316. Under the elastic force of the second spring 316, the telescopic rod 314 and the piston plate 315 keep the pressure roller 312 in contact with the wall. The second spring 316 will not interfere with the signal of the distance sensor 317. The distance sensor 317 is electrically connected to a control component, which can be a PLC controller or other control equipment with control functions.

[0028] Additionally, the rotating shaft 311 is rotatably connected to the support 310. One end of the rotating shaft 311 passes through the support 310 and is fixed with an encoder 313. The encoder 313 is connected to the control unit via a signal. During the ascent of the platform 1, the pressure roller 312 rotates continuously, which drives the encoder 313 to rotate through the rotating shaft 311. The encoder 313 calculates the distance and sends it to the control unit to obtain the real-time ascent height. This is the prior art.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
