[0002] Existing construction material hoists often utilize double-cage material elevators. These are vertical cargo transport devices pulled by wire ropes and driven by a winch. They feature a novel structure, high performance, and easy installation. Equipped with a comprehensive suite of safety devices that meet national standards, they meet the vertical lifting requirements of various industrial and civil construction applications, as well as tall railway and highway bridge piers.

[0003] However, since the transfer vehicles in the existing elevator cage are all placed movably, they are prone to shifting and shaking during the lifting process, and may even collide with the inner wall of the elevator cage, which increases safety hazards. Once an accident occurs, it is very likely to cause a serious safety accident. In terms of safety protection, the existing elevator anti-fall system often only clamps and fixes the slide rails through the anti-fall device. Once accidents such as wire rope breakage and brake failure occur, and when there is a large amount of material in the cage, the friction force of the anti-fall device is difficult to effectively prevent the cage from falling.

[0017] The beneficial effects of the present invention compared to the prior art are:

[0018] 1.

[0019] 2. The present invention can provide all-round and reliable anti-fall protection: the first anti-fall component and the fall protection component form multiple protections; when accidents such as wire rope breakage and brake failure occur, the electric wire take-up machine pulls the cage through the anti-fall rope, and the electric telescopic stop device assists in braking; if the cage falls, the easy-to-open rectangular plate of the airbag frame in the fall protection component opens, the airbag unfolds and wraps the bottom of the cage, and the first spring and the polyurethane buffer block absorb the impact energy; multiple protection structures work together to effectively prevent the cage from falling under extreme circumstances.

[0020] 3. The present invention facilitates the dynamic adaptive adjustment of the operation state of the lifting cage: the pressure-sensitive component cooperates with the pressure-sensitive disk, the pressure-sensitive telescopic column, the connecting block and the friction block. When the cage carries materials of different specifications and weights, the pressure-sensitive disk senses the pressure change and drops, driving the friction block to contact the slide rail column, and automatically adjusts the friction force according to the pressure. The greater the pressure, the greater the friction, and the smaller the pressure, the smaller the friction.

[0021] 4. The present invention facilitates the stable transportation of materials: through the cooperation of the pressure-sensitive telescopic column, the adjustable pressure air tank, the rubber layer and the adjustable air bag, the pressure-sensitive telescopic column detects the pressure and links with the adjustable pressure air tank to adjust the pressure of the adjustable air bag so that the rubber layer fits the material, increasing friction, buffering and shock absorption, improving the material fixing effect and transportation safety, and realizing the function of stable material transportation; at the same time, this cooperation can also automatically adjust the air bag pressure according to the weight of the material, improving the adaptability to different materials, making the rubber layer fit the material tightly and increasing friction.

[0022] 5. The present invention can improve the environmental adaptability and stability of the device: the pressure-stabilizing compensation valve cooperates with the regulating airbag to automatically adjust the airbag pressure according to changes in ambient temperature and air pressure, so that the regulating airbag can work stably in different environments, thereby improving the stability of the device in different environments.

[0023] 6. The present invention has the ability to quickly detect faults and self-repair: by adjusting the conductive polymer coating on the surface of the airbag and cooperating with the microcontroller, it can promptly detect airbag damage and trigger an alarm, quickly locating the damage point; by adjusting the liquid sealant inside the airbag, the damaged area can be automatically repaired, reducing downtime for maintenance and improving the self-repair ability and reliability of the device.

[0047] In this embodiment, the present invention further provides a method for using a material lifting device for high-rise building construction, comprising the following steps:

[0048] Step 1: Fix the base 5 of the lifting device to the designated position on the construction site using anchor bolts through the fixing holes on the fixing mounting plate 6; then vertically splice the standard section 1 through the plug-in holes of the slide rail column 2 and the plug-in column 3 in sequence, reinforce the connection with the clamp frame 4 and the fixing bolts 33, build the lifting column, and install the top mounting platform 28 to complete the construction of the main structure of the lifting device.

[0049] Step 2: Place the transfer cart and materials in the cage 7, and use the two-way electromagnetic lock 16 of the fixed component in the cage 7 to insert the lock tongue into the slot on one side of the arc groove 32 to fix the transfer cart, and at the same time use the L-shaped hanging plate 17 to assist in fixing the materials to ensure that the materials and the transfer cart are fixed in position in the cage 7; when the materials are placed in the cage 7, the pressure-sensitive telescopic columns 36 at the four corners of the cage 7 correspond to four adjustment airbags 40 respectively, and each pressure-sensitive telescopic column 36 separately detects the gravity transmission at a single side and a single corner, senses the pressure change and links to adjust the compressed air tank 41, automatically adjusts the pressure of the adjustment airbag 40, so that the rubber layer 39 fits better to the bottom of the material, increases friction to prevent sliding, and at the same time plays a buffering and shock-absorbing role, further ensuring the material fixation effect and transportation safety.

[0050] Step three, start the electric winch 9, the rotating roller of the electric winch 9 drives the lifting wire rope 13, the lifting wire rope 13 passes through the bottom end of the second pulley group 12 and the upper end of the first pulley group 10 in sequence, pulling the cage 7 to start lifting along the slide rail column 2; the first roller 37 on the cage 7 abuts against the outer wall of the slide rail column 2 to ensure the smooth operation of the cage 7.

[0051] Step 4. When the cage 7 rises and approaches the top mounting platform 28, the first anti-fall component at the top mounting platform 28 begins to work, the electric wire take-up machine 14 keeps the anti-fall rope 15 in a tensioned state, and the electric telescopic stop device 34 is ready to stop at the layer; if an accident such as wire rope breakage or brake failure occurs, the anti-fall device 8 is triggered, and at the same time the electric wire take-up machine 14 quickly tightens the anti-fall rope 15 to pull the cage 7, and the electric telescopic stop device 34 assists in braking; if the cage 7 accidentally falls to the bottom, the easy-to-open rectangular plate 31 on the side of the airbag frame 18 in the fall protection component opens, and the airbag inside it quickly unfolds to wrap the bottom of the cage 7, and the first spring 19 and the polyurethane buffer block 21 play a buffering role to reduce the impact force.

[0052] Step five, when the cage 7 reaches the target floor, the electric winch 9 is turned off, the operator enters the cage 7, releases the two-way electromagnetic lock 16 that fixes the transfer cart, and moves the transfer cart and the material out of the cage 7, completing a material lifting and transportation operation; if the regulating airbag 40 is damaged, the resistance of the conductive polymer coating on its surface suddenly changes, and the microcontroller triggers an alarm after detecting it, and at the same time releases the liquid sealant inside the regulating airbag 40 to repair the damaged point. If the regulating airbag 40 needs to be disassembled and replaced, pull the pull ring 46 on the mounting frame 45 to disengage the snap protrusion 47 from the snap groove of the rectangular groove, and the damaged regulating airbag 40 can be quickly disassembled, and the new regulating airbag 40 can be replaced and then re-inserted into the snap groove to fix it.
