Description

Technical Field

[0001] This utility model relates to the field of fall protection devices, and more particularly to high-rise fall protection devices for building construction. Background Technology

[0002] In the construction industry, high-altitude operations are frequent, and construction workers face the risk of falling from heights. Fall protection devices are mainly driven by the urgent need for safety in high-altitude operations. These devices effectively prevent workers from falling from heights and reduce the risk of injury through physical restraint and cushioning mechanisms.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 212271551U), "This utility model discloses a fall prevention device for construction, including a base. Universal wheels are fixed at the four corners of the base's bottom. First support rods are fixed at both ends of the top two sides of the base. One end of each of the four first support rods is hinged to one end of each of the four second support rods, and the other end of each of the four second support rods is hinged to both ends of a support plate. A waist belt is provided. The device protects construction workers by using a fixed plate, baffle, and guardrail to prevent them from falling. The waist belt is secured to the worker and fastened to a sliding rod using male and female buckles. During the worker's movement, the sliding rod moves synchronously with the waist belt, facilitating movement to different positions and improving work efficiency. If a worker accidentally falls, the pull of the waist belt prevents them from falling, ensuring their safety."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, the utility model requires workers to wear a waist belt to protect them from falling from heights. However, in practice, workers often extend their bodies outside the guardrail to perform their work. When the work site is far away, this not only makes it inconvenient for workers to carry out their work but also greatly increases the risk of falling. Furthermore, moving the entire device requires removing the support from the base plate, which significantly affects the progress of construction work. Therefore, it is necessary to improve the high-rise fall protection device for building construction to solve the above problems. Utility Model Content

[0006] To overcome the safety hazards of workers having to extend their bodies outside the guardrail when the construction site is far away, and the inconvenience of moving the entire device.

[0007] The technical solution of this utility model is as follows: a high-rise fall protection device for building construction, including a movable base, a sliding rail and a protective mechanism. The bottom of the movable base is fixedly connected to a caster wheel, the exterior of the movable base is provided with a protective mechanism, the top of the movable base is fixedly connected to a sliding rail, the left side of the sliding rail is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a first threaded rod, the exterior of the first threaded rod is threaded to a lifting base, the lifting base is slidably connected inside the sliding rail, and the lifting base moves by rotating the first threaded rod.

[0009] Preferably, a first drive wheel is fixedly connected to the outside of the first threaded rod, and a first drive belt is connected to the outside of the first drive wheel. A second motor is fixedly connected to the left side of the lifting base, and a bidirectional threaded rod is fixedly connected to the output end of the second motor.

A lifting platform is provided at the top of the lifting base, and a second sliding block is slidably connected inside the lifting platform. A second rotating rod is rotatably connected inside the second sliding block, and the second rotating rod is rotatably connected inside the first rotating rod. A fixed rod is fixedly connected to the outside of the movable base, and a telescopic rod is fixedly connected inside the fixed rod.

[0013] Preferably, the movable bar has a groove at the relative position of the third sliding block, and the third sliding block is slidably connected inside the groove.

[0014] The beneficial effects of this utility model are as follows: When the fixed construction point of the platform is far away, it is inconvenient to carry out construction work.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment of a high-rise fall arrest device for building construction, including a movable base 1, a sliding rail 21, and a protective mechanism. The bottom of the movable base 1 is fixedly connected to casters 4. A protective mechanism is installed on the outside of the movable base 1. The top of the movable base 1 is fixedly connected to the sliding rail 21. A first motor 22 is fixedly connected to the left side of the sliding rail 21. A first threaded rod 23 is fixedly connected to the output end of the first motor 22. A lifting base 24 is threadedly connected to the outside of the first threaded rod 23. The lifting base 24 is slidably connected inside the sliding rail 21. The lifting base 24 moves by rotating the first threaded rod 23. In use, the movable base 1 is moved by the casters 4. Upon reaching the required position, a protective mechanism is used to protect workers from falling from a height. When the construction point is far away, the first motor 22 operates to rotate the first threaded rod 23. The rotation of the first threaded rod 23 causes the lifting base 24 to slide to both sides a certain distance, preventing workers from leaning out to carry out construction work. The lifting base 24 has a matching groove at the relative position of the sliding rail 21. The lifting base 24 is slidably connected to the inside of the sliding rail 21 through the groove. The sliding rail 21 restricts the sliding of the lifting base 24, preventing it from rotating with the first threaded rod 23, while guiding the lifting base 24 to slide in a straight line and bring the workers closer to the construction point.

[0023] Please see Figure 1 - Figure 4In this embodiment, a first transmission wheel 25 is fixedly connected to the outside of the first threaded rod 23, and a first transmission belt 26 is driven to the outside of the first transmission wheel 25. A second motor 27 is fixedly connected to the left side of the lifting base 24. A bidirectional threaded rod 28 is fixedly connected to the output end of the second motor 27. The bidirectional threaded rod 28 is rotatably connected inside the lifting base 24. A second transmission wheel 29 is fixedly connected to the outside of the bidirectional threaded rod 28, and a second transmission belt 210 is driven to the outside of the second transmission wheel 29. A second threaded connection is made to the outside of the bidirectional threaded rod 28. A sliding block 211 is slidably connected inside the lifting base 24. A first rotating rod 212 is rotatably connected inside the first sliding block 211. A lifting platform 213 is provided on the top of the lifting base 24. A second sliding block 214 is slidably connected inside the lifting platform 213. A second rotating rod 215 is rotatably connected inside the second sliding block 214. The second rotating rod 215 is rotatably connected inside the first rotating rod 212. A fixed rod 216 is fixedly connected to the outside of the movable base 1. A fixed rod 216 is fixedly connected inside the fixed rod 216. The telescopic rod 217 has a sliding rod 218 fixedly connected to its bottom, and a support base 219 fixedly connected to the bottom of the sliding rod 218. The telescopic rod 217 extends the sliding rod 218 and support base 219, thus supporting the movable base 1 and lifting the casters 4 off the ground. This prevents the entire device from moving due to external factors during construction. The lifting base 24 has a groove at a position relative to the first sliding block 211. The first sliding block 211 is slidably connected inside the groove, which restricts the movement of the first sliding block 211. To prevent the first sliding block 211 from disengaging from the lifting base 24, two bidirectional threaded rods 28 and two second transmission wheels 29 are provided. The two bidirectional threaded rods 28 are symmetrically rotatably connected inside the lifting base 24, and the two second transmission wheels 29 are respectively fixedly connected to the outside of the two bidirectional threaded rods 28. The second transmission belt 210 is connected between the two second transmission wheels 29. Through the cooperation of the two second transmission wheels 29 and the second transmission belt 210, the two bidirectional threaded rods 28 rotate synchronously, avoiding the lifting platform 213 from tilting due to one end rotating too fast.

[0024] Please see Figure 1 , Figure 5In this embodiment, the protective mechanism includes a guardrail 31, which is fixedly connected to the top of the lifting platform 213. A second threaded rod 32 is rotatably connected inside the guardrail 31, and a knob 33 is fixedly connected to the top of the second threaded rod 32. A movable rail 34 is threadedly connected to the outside of the second threaded rod 32, and the movable rail 34 is slidably connected to the inside of the guardrail 31. A third sliding block 35 is slidably connected inside the movable rail 34, and a first latch 36 is fixedly connected to the inside of the third sliding block 35. A second latch 36 is snapped into place inside the first latch 36. 7. A protective waist belt 38 is fixedly connected to the inner side of the second buckle 37. The moving bar 34 is raised and lowered by rotating the knob 33, so that the height of the protective waist belt 38 can be adjusted according to the different heights of the construction workers, thereby increasing the overall practicality of the device. The moving bar 34 has a groove at the relative position of the third sliding block 35. The third sliding block 35 is slidably connected inside the groove. The groove restricts the sliding of the third sliding block 35 and prevents the third sliding block 35 from detaching from the moving bar 34. The first buckle 36 and the second buckle 37 are connected to protect the workers from falling from a height.

[0025] During operation, the movable base 1 is moved to the desired position using the casters 4. Then, the telescopic rod 217 is activated, pushing the sliding rod 218 and support base 219 to extend. The support base 219 supports the movable base 1, causing the casters 4 to lift off the ground. Once the movable base 1 is no longer moving, the worker climbs into the lifting platform 213, puts on the protective belt 38, and engages the second buckle 37 with the first buckle 36. Based on their height, the worker rotates the knob 33, which, through the second threaded rod 32, adjusts the movable rail 34 to a suitable height. After adjustment, the second motor 27 operates, and the two second transmission wheels 29 connect to the first... The two transmission belts 210 work together to drive the two bidirectional threaded rods 28 at both ends to rotate synchronously, causing the first sliding block 211 to slide at a uniform speed. Then, through the cooperation of the first rotating rod 212, the second rotating rod 215 and the second sliding block 214, the lifting platform 213 is raised steadily, raising the workers to the required position to carry out construction. When the construction point is far away, the first motor 22 works, and the first transmission wheel 25 cooperates with the first transmission belt 26 to drive the two first threaded rods 23 at both ends to rotate synchronously, so that the lifting base 24 is in a straight line inside the sliding rail 21, allowing the workers to get closer to the construction point and preventing the workers from sticking their bodies out to carry out construction.

[0026] By adding a sliding rail 21, a first motor 22, and a first threaded rod 23, the safety hazards of workers having to extend their bodies outside the guardrail when the construction site is far away are solved, and the problem of inconvenience in moving the entire device is also solved.
