FIG. 1 is a schematic illustration of a slant well track bed non-destructive conditioning method involved in one embodiment of the present invention. Fig. 2 is a schematic diagram of a track lifting process involved in one embodiment of the present invention. Fig. 3 is a schematic view of a work platform according to an embodiment of the present invention. The inclined angle of the inclined shaft track bed in the embodiment is 30 degrees, and the partial track bed sinks, so that the track laid above generates downwarping, and the transportation of ores is influenced. This embodiment provides a method for non-destructive conditioning of a ballast bed in a slant well, with figure 1 showing the configuration of the ballast bed and a track after conditioning, figure 2 showing the configuration of a device for lifting the track, and figure 3 showing the configuration of a work platform for the conditioning process. Referring to fig. 1 to 3, the method includes the following steps:

step S1: a stepped working platform is arranged in a sunken area of the ballast bed to provide a horizontal working surface for a renovating personnel. As shown in fig. 3, the stepped work platform comprises a stepped deck 6 and a balustrade 7. Railing 7 welds the one end of 6 downside of landing slabs, and landing slab 6 is 30 contained angles with railway roadbed 1. The lower end of the working platform can be provided with a stop lever which is arranged in the track bed 1 in a penetrating way so as to prevent the working platform from sliding downwards along the track bed 1. After the work platform is set, the sinking amount of the track bed 1 is measured. Here, a rope may be stretched at both ends of a locally depressed area of the track bed 1, and then the distance between the rope and the track bed is measured, i.e., the amount of the depression of each position of the track bed 1.

Step S2: and manufacturing the sizing block 3 with the same height according to the above sinking amount. Here, the position where the subsidence amount is the largest is explained, but it is needless to say that a plurality of the parallels 3 may be provided between the track 2 and the track bed 1 depending on the subsidence range of the track bed 1. In this embodiment, the shim 3 is an H-shaped shim and is made by welding two flange plates to either side of two webs, with the distance between the outermost ends of the two flange plates being equal to the maximum sinking of the track bed at that point. Then bolt holes are drilled in the upper flange plates on the two sides of the web plate of the sizing block 3 along the length direction.

Step S3: the connection of the rail 2 to the track bed 1 is here opened, after which the rail 2 is lifted by means of the lifting device 8, after which the aforementioned skid 3 is placed between the rail 2 and the track bed 1. In this embodiment, the lifting device 8 comprises four L-shaped lifting hooks 81, a lifting beam 82 and two lifting jacks 83, and the upper ends of the lifting hooks 81 are provided with bolt holes for connecting with the lifting beam 82. In the specific operation process, firstly, the lower end bending part of the lifting hook 81 is placed between the track 2 and the track bed 1, then, the upper end of the lifting hook 81 is fixedly connected with the jacking beam 82 through a bolt, two lifting hooks 81 are respectively arranged on two sides of the track 2 and two sides of the jacking beam 82, then, the jacks 83 are arranged on the lower sides of two ends of the jacking beam 82, the jacks 83 are opened to enable the jacking beam 82 to rise upwards, the track 2 is driven to rise upwards, and finally, the manufactured sizing block 3 is placed between the track 2 and the track bed 1. It is to be noted that, in this embodiment, the length direction of the back iron 3 is the same as that of the rail 2.

Step S4: the lower end of the sizing block 3 is fixedly connected with foundation bolts on the ballast bed 1, and the upper end of the sizing block 3 is fixedly connected with the track 2. Specifically, the lower flange plate of the parallels 3 is welded to the anchor bolts on the track bed 1. The upper flange plate of the sizing block 3 is connected with the rail 2 through bolts and a rail pressing plate 4, and a rubber pad 5 is arranged between the rail 2 and the sizing block 3 to increase the friction force between the two. The track pressing plate 4 is a wedge-shaped section, the lower end face of the track pressing plate is an inclined plane and is in contact with the side edge of the track, and the upper end face of the track pressing plate is a plane. It should be noted that the lifting device 8 is removed when the back iron 3 is connected to the rail 2.

By the nondestructive renovation method for the inclined shaft track bed, the track in the sinking area of the track bed can be lifted and supported, so that the track is in a flat state, and the track cannot be downwarped when a transport vehicle passes through the track. In addition, the H-shaped sizing block can firmly connect the track and the ballast bed together, and the sizing block cannot fall off due to vibration generated in the running process of the transport vehicle, so that the transport vehicle is ensured to run stably.
