Abstract
Description
Technical Field
[0001] The invention relates to a fixing device for a screen cleaning machine, in particular to a device for installing a horizontal guide groove of a screen cleaning machine. Background Art
[0002] The cleaning machine is used to clean the ballast on the track bed. It can perform periodic overhaul and cleaning operations on the track bed to restore the elasticity and drainage performance of the track bed. It will dig out the dirty ballast from the bottom of the sleeper and screen it, backfill the clean ballast into the track bed, and throw the screened dirt out of the line to achieve the purpose of cleaning the gravel track bed.
[0003] The operation of the screen cleaning machine includes: the running system drives the whole vehicle to run, the track lifting device lifts the track, the excavation system digs out the ballast and lifts and transports it to the screening device, the screening device cleans the ballast, and the conveying device backfills and discards the ballast. The excavation system is mainly composed of the excavation chain, lifting guide, excavation chain drive device, horizontal guide, descending guide, angle guide, ballast plate, protective plate, chain tensioning cylinder, lifting cylinder, etc. Before the screen cleaning machine is operated, the horizontal guide and some chain links need to be installed first.
[0004] During installation, part of the ballast is first dug out manually to form a foundation pit below the rail with a depth of 400 to 500 mm from the bottom of the sleeper, a sleeper spacing of 1,500 mm, and a 700 mm extension on both sides of the sleeper ends; then the operator lifts the horizontal guide from the car into the foundation pit, adjusts the lowering guide and the lifting guide to the bottom of the rail by adjusting the oil cylinder, and lifts the horizontal guide with the help of simple lifting equipment. The operator directly moves the horizontal guide to adjust the position of the horizontal guide; after the end faces of the two sides of the horizontal guide are aligned with the end faces of the angle guide, the horizontal guide is connected to the angle guide with quick connection pins and bolts. After the installation of the horizontal guide is completed, the chain link is installed to make the digging chain bypass the rail to form a closed loop, and finally the digging chain is tensioned with the tensioning cylinder to complete the installation of the digging chain system.
[0005] The horizontal guide trough weighs 150kg and requires four people to carry it during installation and removal. It is labor-intensive, takes a long time to install, and is difficult to adjust. In addition, the operation takes place at night, which poses a high safety risk. The length of the horizontal guide trough of the cleaning machine is greater than the distance inside the rail, so the horizontal guide trough cannot be directly placed from the bottom of the cleaning locomotive to the bottom of the rail, making installation difficult. The cleaning machine has a short operating window, and the installation of the horizontal guide trough takes up a lot of time, which seriously restricts the operating efficiency of the cleaning machine.

Then the lateral adjustment cylinder 13 is extended, and the lateral slide arm 11 moves a certain distance along the lateral guide arm 10 under the action of the lateral adjustment cylinder 13, so that one end of the horizontal guide groove passes through one side of the rail from the center of the ballast bed toward the ballast bed slope direction, such as Figure 4 As shown;
[0110] 2c. Then adjust the telescopic arm luffing cylinder 5 and the telescopic arm telescopic cylinder 4-0 to extend, and cooperate with the swing of the secondary spiral swing cylinder 8 to make the horizontal guide groove move from Figure 4 The position shown is continuously moved in a direction horizontal to the ground, so that the horizontal guide groove passes through the ballast bed under the rail and finally becomes parallel to the ground;
[0111] 2d. By controlling the retraction of the lateral adjustment cylinder 13, the other end of the horizontal guide groove also moves below the rail and is ultimately located in the middle of the rail;
[0112] (3) The end faces of the horizontal guide groove and the angle guide groove are aligned:
[0113] 3a. Extend or shorten the boom luffing cylinder 3, extend or shorten the telescopic boom luffing cylinder 5, extend or shorten the telescopic boom telescopic cylinder 4-0, and swing the primary spiral swing cylinder 6 forward or backward, so that the horizontal guide groove moves toward the position close to the angle guide groove, and finally align the end surface of the horizontal guide groove with the end surface of the angle guide groove, as shown in FIG. Figure 5 shown.
[0114] (4) Horizontal guide groove fixing and digging chain installation:
[0115] 4a. After the end faces of the horizontal guide groove and the angle guide groove are aligned, use quick-connect pins and bolts to connect the horizontal guide groove and the angle guide groove;
[0116] 4b. After the horizontal guide groove is installed, chain links are installed in the horizontal guide groove and the angle guide groove so that the digging chain bypasses the rail 14 to form a closed loop. Finally, the digging chain is tensioned with a tensioning cylinder to complete the installation of the digging chain system.
[0117] Perform steps 1a, 1b, 1c, 1d, 2a, 2b, 2c, 2d, 3a, 4a, and 4b in sequence.
[0118] In this example, the position of the horizontal guide groove is adjusted by the boom luffing cylinder, the telescopic arm luffing cylinder, the telescopic arm telescopic cylinder and the first-stage swing cylinder. The boom luffing cylinder is extended and retracted a small length, and after being magnified by each arm section, the horizontal guide groove moves significantly. Therefore, the boom luffing cylinder is used to coarsely adjust the position of the horizontal guide groove.
