The guide rail support of the traditional hoist is mainly fixed on the ground, and in the high-rise building transportation or strong wind environment, it is easy to shake, which leads to material deviation or even falling. Some equipment lacks real-time speed monitoring and emergency braking linkage mechanism, and when abnormal conditions such as overspeed and jam occur, it is difficult to control in time, which easily increases the risk of safety accidents. The door body of the existing hoist is mainly designed by manual push-pull type, without auxiliary counterweight structure, and for larger size or heavier door body, the operator needs to exert more effort when opening and closing.

The driven disc 703 is connected with the regenerative braking system 800 through the driven shaft 706.

[0060] When the cage body 100 runs upward, the driving disc 702 rotates forward with the driving gear 705 engaged with the rack 203, the transmission block 707 slides along the inclined transmission groove 709 of the driven disc 703 and gradually separates from the driven disc 703, the driving disc 702 and the driven disc 703 are separated, and the power is not transmitted to the regenerative braking system 800, thereby reducing the upward energy consumption.

[0061] When the cage body 100 runs downward, the driving disc 702 rotates reversely, the transmission block 707 is clamped into the transmission groove 709 along the inclined surface of the transmission groove 709 under the pushing force of the spring 708, the driving disc 702 drives the driven disc 703 to rotate synchronously, the driven disc 703 transmits power to the regenerative braking system 800 through the driven shaft 706, and the power generation and speed reduction linkage are realized.

[0062] Please refer to Figures 1-10 In one specific embodiment of the present application, the regenerative braking system 800 includes a generator 801, the generator 801 is drivingly connected with the clutch assembly 700, a driven pulley 802 is fixedly installed on the power input shaft of the generator 801, a driving pulley 803 is fixedly installed on the driven shaft 706 in the clutch assembly 700 corresponding to the driven pulley 802, and a toothed belt 804 is sleeved outside the driving pulley 803 and the driven pulley 802; the generator 801 is drivingly connected with the driven shaft 706 of the clutch assembly 700 through the driven pulley 802 and the toothed belt 804; a plurality of annularly distributed armature winding modules are installed on the stator core of the generator 801, the armature winding modules are electrically connected with a power storage module, an electrically controlled on-off module is electrically connected between the armature winding modules and the power storage module, and the electrically controlled on-off module is electrically connected with the control system 900.

[0063] In the working process, the regenerative braking system 800 realizes energy recovery through mechanical transmission and electromagnetic induction, and is the core of equipment energy saving and auxiliary braking. When the clutch assembly 700 is combined, the driven shaft 706 drives the driving pulley 803 to rotate, drives the driven pulley 802 through the toothed belt 804, and then drives the power input shaft of the generator 801 to rotate. Inside the generator 801, the rotating rotor cuts the magnetic induction lines of the armature winding modules on the stator core, generates induced electromotive force, and realizes the conversion of mechanical energy to electrical energy. The generated electrical energy is transmitted through the circuit, and is charged and stored in the power storage module through the electrically controlled on-off module.

[0064] Meanwhile, the electromagnetic force generated by the energization of the armature winding module hinders the rotation of the rotor, forming a braking force, which assists the descending and deceleration of the cage body 100. Since the electrically controlled on-off module is connected to each of the plurality of ring-shaped and uniformly distributed armature winding modules, and the electrically controlled on-off module is controlled by the control system 900, the control system 900 can control the electromagnetic force generated by the energization of the armature winding module by controlling the number of the armature winding modules that are energized, thereby achieving the control of the braking force.

[0065] Please refer to ​ In one specific embodiment of the present application, the control system 900 comprises a controller 901, which is fixedly installed on the cage body 100, and the controller 901 is electrically connected with the driving assembly 500, the speed measuring assembly 600 and the regenerative braking system 800. The controller 901 is wirelessly connected with a mobile terminal 902, and the mobile terminal 902 is provided with a control button 903 and a display 904.

[0066] During the operation, the control system 900 is the core of the material hoist, and the intelligent operation of the equipment is realized through information interaction and instruction control. The controller 901 fixed on the cage body 100 as the core receives the real-time speed data transmitted by the speed measuring assembly 600, and is electrically connected with the driving assembly 500 and the regenerative braking system 800. The operator sends instructions through the control button 903 of the mobile terminal 902, which is wirelessly transmitted to the controller 901. The controller 901 controls the start-stop and rotating speed of the driving assembly 500 according to the instructions and the speed data, so as to realize the lifting control of the cage body 100. Meanwhile, the controller 901 controls the on-off of the electrically controlled switch in the regenerative braking system 800, and manages the storage of electric energy. The mobile terminal 902 can display the running parameters of the equipment in real time, and forms a closed-loop control.

[0067] The implementation principle of the material hoist in the embodiment of the present application is as follows: The present application takes the coordinated linkage of multiple assemblies as the core, and realizes the efficient and safe vertical transportation of materials through the whole-process design of support positioning, power driving, safety protection and energy recovery. Firstly, during the installation of the equipment, the guide rail assembly 200 is fixed to the ground through the bottom of the vertical tower 201, and is connected to the building through the side, thereby forming a bidirectional stable support. The symmetrically arranged guide rails 202 provide a vertical running path for the cage body 100, and the rack 203 provides a transmission basis for the driving, speed measuring and clutch assemblies, thereby completing the basic positioning of the equipment operation. When the material transportation starts, the operator first loads and unloads materials through the lifting door assembly 300: pushes the door body 303, the bottom traction frame 305 drives the counterweight block 308 to slide through the pull rope 309 and the pull rope pulley 307, the gravity of the counterweight block 308 assists to offset part of the weight of the door body 303, and reduces the opening and closing operation force; the door body 303 stably rises and falls along the door frame sliding rail 301 through the door frame pulley 302 and the door body pulley 304, and forms double protection with the outer net plate 103 of the cage main body 100 after being closed, so as to avoid material falling. Subsequently, the mobile terminal 902 of the control system 900 sends a start instruction, and the controller 901 receives the start instruction and starts the drive assembly 500: the electric motor 501 outputs power, the power is reduced and the torque is increased through the speed reducer 502, the drive gear 503 is engaged with the rack 203, and the rotary motion is converted into the linear lifting motion of the cage main body 100. At this time, the first, second and third guide rail pulleys of the guide assembly 400 on the back of the cage main body 100 are connected with the guide rail 202 from different directions to form a three-dimensional limit, so as to ensure that the cage main body 100 stably runs along the guide rail 202 and avoids deviation and shaking. During transportation, the speed measurement assembly 600 monitors in real time: the gear 602 is engaged with the rack 203 to rotate, the rotation speed sensor 601 captures the rotation speed signal and transmits it to the controller 901, the controller 901 analyzes the speed data, and if overspeed or abnormality occurs, immediately adjusts the rotation speed of the drive assembly 500 to ensure operation safety. When the cage main body 100 goes up, the driving disc 702 of the clutch assembly 700 rotates forward with the rack 203, the transmission block 707 is separated under the action of the inclined surface of the transmission groove 709, the driving disc 702 is separated from the driven disc 703, the regenerative braking system 800 is not started, and the uplink energy consumption is reduced; when going down, the driving disc 702 rotates reversely, the transmission block 707 is clamped into the transmission groove 709 under the pushing force of the spring 708, the driven disc 703 rotates with the driving disc 702, the driving shaft 706, the driving pulley 803 and the toothed belt 804 drive the driven pulley 802 of the generator 801 to rotate, the rotor of the generator 801 cuts the magnetic induction line of the armature winding module to generate electric energy, which is stored in the storage module through the electric control on-off module, and energy recovery is realized. At the same time, the electromagnetic force generated by the energized armature winding module hinders the rotation of the rotor, forming a braking force to assist in deceleration; the controller 901 can control the electromagnetic force by adjusting the number of energized armature winding modules, accurately adapt to the deceleration requirement under different loads, and further improve the downlink safety. During the whole operation process, the control system 900 always serves as the hub, integrates the state monitoring of the speed measurement assembly, the power regulation of the drive assembly and the energy management of the regenerative braking system, realizes intelligent operation of the whole process of the equipment, and finally achieves the dual goals of safe material transportation and efficient energy utilization.
