Description

Technical Field

[0001] The invention belongs to the technical field of building construction lifting devices, in particular to a material lifting device for high-rise building construction. Background Art

[0002] The existing material lifting devices for construction use double-cage material hoists, which are cargo-type vertical transportation equipment pulled by steel wire ropes and driven by winches. They have novel structures, high performance and are easy to install. Double-cage material hoists are equipped with a full set of safety devices that meet national standards and can meet the requirements for vertical lifting of materials in the construction of various industrial and civil buildings, as well as high-rise bridge piers of railways and highways.

[0003] However, since the transfer vehicles in the existing elevator cages 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-falling system often only clamps and fixes the slide rails through a fall arrester. 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 fall arrester is difficult to effectively prevent the cage from falling.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: 1. The present invention can achieve precise positioning of the transfer vehicle and improve transportation stability: In the fixing component, the double-sided electromagnetic lock cooperates with the arc-shaped groove and the L-shaped hanging plate. The locking tongue of the double-sided electromagnetic lock is inserted into the slot of the arc-shaped groove to fix the transfer vehicle, and the L-shaped hanging plate assists in fixing the material, effectively restricting the position of the transfer vehicle in the cage, preventing it from shifting, shaking and colliding during the lifting process. Compared with the traditional lifting device, the stability and safety of the transportation process are greatly improved, and the precise positioning function of the transfer vehicle in the cage is realized.

[0015] 2. The present invention can provide comprehensive and reliable anti-falling protection: The first anti-falling component and the fall protection component form multiple protections; when accidents such as steel wire rope breakage and braking failure occur, the electric wire winding machine pulls the cage through the anti-falling rope, and the electric telescopic stop layer device assists in braking; if the cage falls, the easy-opening rectangular plate of the airbag frame in the fall protection component opens, the airbag unfolds to wrap the bottom of the cage, and the first spring and the polyurethane buffer block absorb the impact energy; the cooperation of multiple protection structures can effectively prevent the cage from falling in extreme cases. Compared with the problem of insufficient safety protection of the existing lifting device, the present invention greatly improves the safety protection ability in the face of emergencies and realizes the comprehensive and reliable anti-falling protection function.

[0016] 3. The present invention facilitates the dynamic adaptive adjustment of the operating state of the cage: the pressure-sensitive component cooperates through 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. The cage can automatically and accurately adjust the operating stability according to the material status, effectively avoiding the problem of unstable operation caused by material differences, improving the cage's adaptability to different materials, and realizing the function of the cage dynamically and adaptively adjusting the operating state according to the material specifications.

[0017] 4. The present invention facilitates the stable transportation of materials: through the cooperation between the pressure-sensitive telescopic column, the adjustable air tank, the rubber layer and the adjustable air bag, the pressure-sensitive telescopic column detects the pressure and links with the adjustable air tank to adjust the pressure of the 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 transportation of materials; 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 closely and increasing friction.

[0018] 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.

[0019] 6. The present invention has the ability of rapid fault detection 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, and quickly locate the damaged point; by adjusting the liquid sealant inside the airbag, the damaged part can be automatically repaired, reducing downtime for maintenance and improving the self-repair ability and reliability of the device.

[0034] In this embodiment, the present invention also proposes a method for using a material lifting device for high-rise building construction, comprising the following steps: Step 1: Fix the base 5 of the lifting device at the designated position on the construction site through the fixing holes on the fixing mounting plate 6 using anchor bolts; 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.

[0035] Step two, place the transfer cart and the material in the cage 7, use the two-way electromagnetic lock 16 of the fixed component in the cage 7, insert the lock tongue into the slot on one side of the arc groove 32 to fix the transfer cart, and use the L-shaped hanging plate 17 to assist in fixing the material to ensure that the material and the transfer cart are fixed in position in the cage 7; when the material is placed in the cage 7, the pressure-sensitive telescopic columns 36 at the four corners of the cage 7 correspond to four adjusting airbags 40 respectively, 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 adjusting airbag 40, so that the rubber layer 39 better fits 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.

[0036] 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, and pulls 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. During the lifting process, the pressure-sensitive disk 22 senses the weight of the material in real time.

[0037] Step four, 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 layer stop device 34 is ready to stop; if an unexpected situation 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 hold the cage 7, and the electric telescopic layer 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.

[0038] Step Five: After the cage 7 reaches the target floor, turn off the electric hoist 9. The operator enters the cage 7, releases the fixation of the transfer vehicle by the bi-directional electromagnetic lock 16, and removes the transfer vehicle and the materials from the cage 7, thus completing a material lifting and transportation operation. If the adjusting airbag 40 is damaged, the resistance of the conductive polymer coating on its surface mutates. After being detected by the microcontroller, an alarm is triggered, and at the same time, the liquid sealant inside the adjusting airbag 40 is released to repair the damaged point. If it is necessary to disassemble and replace the adjusting airbag 40, pull the easy-pull ring 46 on the mounting frame 45 to make the buckle protrusion 47 disengage from the buckle groove of the rectangular groove, and then the damaged adjusting airbag 40 can be quickly disassembled. After replacing the new adjusting airbag 40, snap it back into the card slot for fixation.
