G1) the method comprises the following steps Starting the hoisting device 3 to enable the truss girder 1 to operate between +15 degrees and-15 degrees so as to determine the position of the limit switch, and if vibration, noise or leakage phenomena occur during the operation of the hoisting device 3, immediately stopping the machine, finding out reasons and removing the reasons in time;

G3) the method comprises the following steps Placing the truss girder 1 in a horizontal position, starting the stacking conveyor 18, observing the running conditions of all carrier rollers, paying attention to observing whether the belt deviates, and finding out reasons and timely eliminating the reasons if the carrier roller runs inflexibly or the belt deviates; after the fault is eliminated, the empty load operation of the stacking conveyor is not less than 2 hours, and the temperature rise condition of the speed reducer is observed;

G4) the method comprises the following steps Starting the cable reel 10, checking whether the cable reel 10 has a problem; the running gear 6 is allowed to run after the cable reel 10 has no problem;

G5) the method comprises the following steps Starting the traveling device 6 of the retaining wall stacker, observing the temperature rise of the speed reducer when the running time is not less than 2 hours, and detecting whether the traveling wheel 22, the anti-overturning wheel 4 and the driven wheel assembly 17 have a rail clamping phenomenon with the steel rail or not;

G6) the method comprises the following steps Determining the position of a walking limit switch during the operation of the retaining wall stacker, and fixing the walking limit device after the position is adjusted;

G7) the method comprises the following steps After each part of the stacker for the retaining wall normally operates, the whole stacker for the retaining wall performs linkage empty load test run, the running time is not less than 48 hours, and the stacker for the retaining wall and an external material receiver perform linkage test run for not less than 48 hours;

the load debugging comprises the following steps:

H1) the method comprises the following steps Feeding materials to a stacking conveyor 18, and carrying out a partial load trial run for not less than 12 hours, wherein the partial load is 25-50% of a full load; gradually increasing the load when testing partial load, and finally reaching the full load degree;

H2) the full-load test run can be carried out only when part of the load test runs have no problem, and the full-load operation can be put into production all normally.

In step H1), when the material is fed to the stacking conveyor 18, the stacking conveyor 18 must reach the normal operation speed before the material can be fed to the stacking conveyor 18, and the material cannot be fed when the stacking conveyor 18 is stationary;

the method for judging the full load operation to be normal in step H2) is: when the belt conveyor runs under load, the material flow detection device, the cleaning device, the belt and the roller on the stacking conveyor 18 are observed and adjusted to be slipped or not besides the normal running of the belt conveyor is observed when the belt conveyor is debugged and run according to the empty load;

when the tensioning device is adjusted, the truss girder 1 is in a horizontal position state, the belt droop value between two carrier rollers of the stacking conveyor 18 is observed, and the normal operation is realized when the droop value does not exceed 1.5% of the distance between the carrier rollers; whether the cantilever lifting distance is normal when the truss girder 1 is lifted each time and whether the walking distance is normal when the retaining wall stacker walks are observed, and if the lifting distance and the walking distance are both normal, the operation is normal.

In the test run, the process of stopping the machine is required to be carried out when each item is checked to have the unqualified requirement, and after the machine is operated again, each requirement is required to be rechecked until all the requirements are qualified.

In the test run, after the accident treatment for the fault parking is finished, the test run time needs to be recalculated when the vehicle is driven again, and the test run time cannot be accumulated before and after the vehicle is driven again.

The construction method is used for installing the equipment, so that the installation time of the equipment is shortened, the purpose of saving the construction period is achieved, and the installation efficiency and the installation quality of the equipment are improved.

The working process of the stacker for the retaining wall is as follows:

the materials are transmitted through an external feeding machine 24, the external feeding machine 24 is laid in a stock ground and extends to a retaining wall stocker from a far end all the time, the external feeding machine 24 transmits the materials to a feeding vehicle, the feeding vehicle conveys the materials to a hopper 20, then the materials are discharged onto a stacker conveyor 18 through the hopper 20 and are discharged from the head of the truss girder 1 to form a conical stack, the material level detector detects the materials in the process of forming the stack, if the stack touches the material level detector, a signal is sent to a controller of a control room 8, the controller sends a signal to a hoisting device 3, and the hoisting device 3 drives the truss girder 1 to rise to a preset angle and continue discharging; when the material pile reaches the preset height, the controller sends an instruction to enable the material piling machine for the retaining wall to walk for a certain distance according to the instruction, and then the material piling process at the next fixed point is carried out until the material piling operation of the material piling area of the material storage bin is completed or the material piling and stopping are carried out after a pile changing or stopping instruction is received. The retaining wall is moved by the stacker, and the materials are discharged into a stock ground at the same time to form a layered herringbone stock pile, so that the uniform mixing effect is completed for the taking-away of the reclaimer.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
