[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 In the utility model, an energy-saving building construction lifting and anti-falling device includes a mounting frame 1, both sides of the mounting frame 1 are fixedly connected with convex guide rails 2, a winder 3 is fixedly installed on the top of the mounting frame 1, a car 4 is slidably installed between the convex guide rails 2, the winder 3 is fixedly connected to the top of the car 4 through a steel cable, both sides of the bottom of the car 4 and the convex guide rails 2 are installed with brake components 5, two positioning frames 6 are rotatably installed on the top of the mounting frame 1, and the outer side of the positioning frame 6 is transmission-connected with a closed steel wire 8 fixedly connected head and tail, and two follower plates 9 are installed at the bottom of the mounting frame 1, the steel wire 8 is transmission-connected to the follower plate 9, and the outer side of the steel wire 8 is connected and matched with the brake component 5.

[0023] In the utility model, the mounting frame 1 is used as the mounting support of the device. When in use, the car 4 is used to carry people and materials, and then the winder 3 is started to drive the car 4 to rise and fall along the two convex guide rails 2. During the lifting and falling, the two brake members 5 at the bottom of the car 4 always follow along the convex guide rails 2, and at the same time drive the two steel wires 8 to drive the positioning frame 6 and the following disk 9 at the bottom to rotate synchronously. When the car 4 suddenly falls, the car 4 drives the steel wire 8 to run at an overspeed, so as to drive the positioning frame 6 to rotate at an overspeed. At this time, under the action of the centrifugal force of the rotation, the positioning frame 6 is stuck, and the steel wire 8 is pressed. The limit stop is achieved, and at this time, the steel wire 8 has a speed difference with the car 4, which will drive the brake part 5 at the bottom to contact the convex guide rail 2 to achieve braking deceleration and finally stop, thereby preventing falling. As a result, the device does not need electric drive, and can work stably during power outages, with the advantages of good deceleration and anti-falling effects. It solves the problem of the power structure in the prior art being driven and implemented. Such a structure has the limitation of being unable to work after a power outage, and when the motor fails, it will make it impossible to decelerate, and it may even cause the lifting structure to be stuck and unable to move, resulting in poor use effect and great limitations.

[0024] See also Figure 4 , wherein: the brake member 5 includes a connecting arm 51, a rotating rod 52, two extrusion blocks 53, two clamping blocks 54 and a connecting block 55, one end of the connecting arm 51 is hinged to the outside of the steel wire 8, the other end of the connecting arm 51 is fixedly connected to one end of the rotating rod 52, the rotating rod 52 is inserted into the interior of the connecting block 55 and is fixedly connected to the two extrusion blocks 53, the top of the connecting block 55 is fixedly connected to the bottom of the car 4, the interior of the connecting block 55 is slidably connected to the convex guide rail 2, the two extrusion blocks 53 are relatively slidably arranged inside the connecting block 55, and the two extrusion blocks 53 are relatively arranged on both sides of the convex guide rail 2.

[0025] In the utility model, after the steel wire 8 is stuck and decelerated, the connecting arm 51 is pulled to drive the rotating rod 52 to rotate, and the rotating rod 52 drives the two extrusion blocks 53 to deflect and squeeze the two clamping blocks 54 to run relatively along the inside of the connecting block 55 and contact the two sides of the convex guide rail 2 to achieve extrusion friction deceleration, thereby preventing falling.

[0026] See also Figure 4 , wherein: two horizontal springs 531 are fixedly connected to the outer sides of the two extrusion blocks 53 , and the other ends of the two horizontal springs 531 are fixedly connected to the inside of the connection block 55 .

[0027] In the utility model, the horizontal spring 531 ensures that the connecting block 55 is in a stable position when the device is operating normally, and the structural stability is better.

[0028] See also Figure 2 and Figure 3, wherein: the positioning frame 6 includes a fixed frame 61, an outer guide wheel 62, an inner turntable 63 and a centrifugal clamp 64, the fixed frame 61 is fixedly installed on the top of the mounting frame 1, the outer guide wheel 62 and the inner turntable 63 are integrally rotatably connected to the fixed frame 61, the centrifugal clamp 64 is installed on the inner turntable 63, and the centrifugal clamp 64 cooperates with the fixed frame 61.

[0029] In the utility model, the outer guide pulley 62 and the inner turntable 63 are driven to rotate synchronously by the steel wire 8. When the equipment is operating normally, the rotation speeds of the outer guide pulley 62 and the inner turntable 63 are normal. At this time, the centrifugal clamp 64 maintains the initial state. When the car 4 falls and slides, the speed of the steel wire 8 is increased. At this time, the rotation speeds of the outer guide pulley 62 and the inner turntable 63 increase and the centrifugal force increases, so that the centrifugal clamp 64 can be unfolded and clamped with the fixed frame 61, so as to realize the positioning of the outer guide pulley 62 and the inner turntable 63, and limit the operation of the steel wire 8 to pull the brake member 5 to decelerate the car 4 and gradually stop it.

[0030] See also Figure 2 and Figure 3 , wherein: the centrifugal clamp 64 includes a first positioning rod 641, a telescopic rod 642, a tension spring 643, two clamping rods 644 and two second positioning rods 645, one end of the first positioning rod 641 and the two second positioning rods 645 are fixedly connected to the inner turntable 63, the middle parts of the two clamping rods 644 are rotatably connected to the two second positioning rods 645 respectively, the top end of the left clamping rod 644 is hinged to the left end of the telescopic rod 642, and the bottom ends of the two clamping rods 644 are hinged through a cross bar, the tension spring 643 is sleeved on the outside of the inner rod of the telescopic rod 642, and one end of the tension spring 643 is fixedly connected to the first positioning rod 641, and the other end of the tension spring 643 is fixedly connected to the end of the outer sleeve of the telescopic rod 642.

[0031] In the utility model, by overspeeding the outer guide wheel 62 and the inner turntable 63, the centrifugal force increases, and the two hook ends of the two clamping rods 644 gradually expand outward, and under the positioning action of the two second positioning rods 645, the two clamping rods 644 are deflected with the second positioning rods 645, and the inwardly deflected ends of the two clamping rods 644 transmit force to compress the telescopic rod 642 so that it compresses the tension spring 643 to achieve deformation, while in the normal working room, the tension spring 643 tightens and positions the telescopic rod 642, ensuring that the overspeeding of the outer guide wheel 62 and the inner turntable 63 is not affected by the normal rotation.

[0032] See also Figure 1 , wherein: a bottom plate 10 is fixedly connected to the bottom of the inner side of the mounting frame 1 , and a buffer hydraulic pressure device 7 is fixedly mounted on the bottom plate 10 .

[0033] In the utility model, bottom protection is achieved by the buffer hydraulic device 7 on the bottom plate 10, which increases safety when the above structure fails and the car 4 is close to the bottom.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
