A limiting device for limiting the hanging basket 5 and the hanging scaffold 6 to continuously go upwards is arranged below the temporary derrick 1, so that the temporary derrick 1 is prevented from being collided by misoperation, and the safety of personnel is effectively protected. When the hanging basket reversing wheel 33 and the left and right reversing wheels 23 and 43 are installed at the top of the temporary derrick 1, the temporary derrick 1 needs to be separated by insulating materials, and when bolts penetrate through connecting holes of the hanging basket reversing wheel 33 and the left and right reversing wheels 23 and 43, the hanging basket reversing wheel and the left and right reversing wheels need to be separated by insulating rubber pipes, so that the steel wire rope and the temporary derrick can be protected in an insulating way. And an insulating pipe is required to be arranged on a steel wire rope for connecting a hanging basket and a hanging scaffold, so that the steel wire rope is prevented from being damaged by welding operation.
After the installation of the hoisting device for the installation of the operation shaft of the LPG underground cave depot is finished, a load test needs to be carried out on the hanging scaffold and the hanging basket so as to verify the operation stability and the operation safety of a hoisting system of the hoisting machine. When the hoist lifting device is used in the field, it is necessary to control the position of the basket 5 and the platform 6 in the operating shaft by means of the lifting system of the basket hoist 30 and the two left and right winches 20, 40. After the hanging scaffold 6 descends to a required operation height, a plurality of lead screws 7 at the bottom of the hanging scaffold 6 are respectively fixed on the well wall and used for placing the hanging scaffold 6 to rotate. The hanging scaffold 6 is a construction operation platform and is used for completing the construction of the anchor plate and the sleeve support. Once the platform 6 is put into use, it is only allowed to descend and not to rise. The hanging basket 5 can be stably operated up and down by taking the left and right steel wire ropes 21 and 41 as a guide above the hanging scaffold 6, and is used for conveying constructors and materials in the well.
The hoisting lifting device for installing the LPG underground cave depot operation shaft is simple in structure, safe and reliable, can provide a safe and stable construction platform for installing the LPG underground cave depot operation shaft by controlling the height of the hanging scaffold and the hanging basket in the operation shaft through the hoisting machine, can realize safe conveying of constructors and materials, effectively ensures the safety of the constructors, greatly improves the installation efficiency of the LPG underground cave depot operation shaft, and is beneficial to promoting the high-speed development of the underground water seal cave depot.
