Embodiment 1

[0020] Such as Figure 1-2 As shown in , a gravel transfer lifting system and method for vortex cavern construction, including cavern crane 1, loading vehicle 6 and shaft top crane 12, cavern crane 1 is installed in the cavern at the top of the vertical section 16 of the cavern On the driving running guide rail 4 of the truss 19, the loading vehicle 6 is installed on the loading vehicle running guide rail 8 located in the straight section 15 of the cavern. One end of the loading vehicle 6 is connected with the loading vehicle traction device 11 through a traction rope, and the loading Car 6 is also provided with hydraulic self-unloading device, shaft top driving 12 is arranged on the outside of shaft top, and shaft bottom is provided with unloading pit 9.

[0021] With this structure, the construction stone slag 17 in the vortex cavern can be vertically hoisted into the loading vehicle 6 installed in the straight section 15 of the cavern by the cavern crane 1 arranged on the t...

Embodiment 2

[0027] Using the transfer lifting system involved in embodiment 1 to carry out the method for transferring and lifting the eddy current cavern construction gravel, the steps are:

[0028] 1. Put the construction gravel 17 in the vortex tunnel into the first hanging basket 5;

[0029] 2. The cavern crane 3 on the cavern crane 1 vertically lifts the first hanging basket 5 with the construction gravel 17 at the bottom of the vortex cavern, and then horizontally transports the construction gravel 17 to the cavern along the running guide rail 4. On the loading cart 6 in the straight section 15 of the chamber;

[0030] 3. The loading vehicle 6 moves along the loading vehicle running guide rail 8 through the loading vehicle traction device 11 to the loading vehicle stopper 7 near the unloading pit 9 at the bottom of the shaft, and stops at 7, and unloads to the first through the hydraulic self-unloading device In the second hanging basket 10, after the unloading is completed, the tr...

Abstract

The invention relates to a rock ballast transferring and lifting system and method in eddy chamber construction. The rock ballast transferring and lifting system comprises a chamber travelling crane, a loading trolley and a travelling crane at the top of a vertical shaft, wherein the chamber travelling crane is installed on a travelling operating guide rail located on a chamber truss at the top of the vertical section of a chamber; the loading trolley is installed on a loading trolley operating guide rail located on a straight section of the chamber, one end of the loading trolley is connected with a loading trolley draft gear through a tow rope, and a hydraulic self-unloading device is arranged on the loading trolley; the travelling crane at the top of the vertical shaft is arranged on the outer side of the top of the vertical shaft, and the bottom of the vertical shaft is provided with an unloading pit. According to the rock ballast transferring and lifting system in eddy chamber construction, the travelling cranes are arranged in the chamber and used in cooperation with the loading trolley with the draft gear to transfer and lift rock ballast of construction in the eddy chamber to the outside of the chamber. The rock ballast transferring and lifting system is simple in structure and convenient to operate, saves time and labor, greatly improves the efficiency of excavating and transporting the rock ballast outwards in the narrow construction space in the eddy chamber and guarantees safety of operators.

Description

technical field [0001] The invention relates to a transfer and lifting system and method, in particular to a gravel transfer and lifting system and method for the excavation construction of a vortex cavern. Background technique [0002] Water conservancy and hydropower vortex caverns are often designed in a circular or broken line, and the speed of the gravel generated during the excavation construction determines the excavation efficiency of the vortex cavern. The lifting device for external transport is often to install a cantilever crane at the end of the broken line cavern, and complete the transfer of gravel by manual transfer. Hidden danger. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a system and method for transporting and lifting gravel in vortex cavern construction. By setting up a crane in the cavern and cooperating with a loading vehicle with a traction device, the gravel in construction in the v...
