Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a fast drilling device for a rail. Background Art

[0002] In coal mining, rail connection holes are widely used in track laying, connection, and maintenance. These holes connect multiple rails, providing fundamental support for coal mine train operation. A rail drilling device, a punching tool used to drill holes at the rail interface and where the rail splints connect, acts as a punching die. Holes drilled using this method comply with the Coal Mine Safety Regulations, the Production Mine Quality Standardization Standard, and the Mine Rail Quality Standard and Stringing Maintenance Regulations.

[0003] Currently, rails are typically shipped in 8-meter lengths. To facilitate underground installation, they must be cut into 4-meter lengths, which requires re-drilling. Each installation requires approximately 500 rails, a large number that is slow and inaccurate due to conventional drilling. Summary of the Invention

[0004] The utility model aims to provide a rail fast drilling device which is suitable for a vertical drilling machine and can quickly and accurately measure the hole position and drill the hole.

[0005] The technical solution adopted by the utility model is: a rapid punching device for rails, comprising a base, a bracket, a positioning plate, a pneumatic cylinder, a punching block and a clamping block; two brackets are provided, and the two brackets are parallel to each other and vertically installed on the base; the top edge of one of the brackets is rotatably connected to one end of the positioning plate, and the protrusion at the other end of the positioning plate can cooperate with the groove of the other bracket; punching blocks are fixedly provided on the two side brackets in front of the positioning plate, and drill holes are provided on the punching blocks; a hole for the clamping block to pass through is opened on the bracket below the punching block, and the clamping block is connected to the telescopic rod of the pneumatic cylinder, and the pneumatic cylinder is fixed to the base through the pneumatic cylinder support frame.

[0006] Furthermore, reinforcing ribs are provided between the base and the bracket.

[0007] Furthermore, the ends of the two brackets are fixedly connected via a connecting plate.

[0008] Furthermore, a rail support block is provided on the base below the clamping block.

[0009] The beneficial effects of the utility model are as follows: the utility model improves the drilling efficiency of the rail, eliminates the need to use a ruler to measure the distance between the drill holes, and the cylinder clamps quickly and the eye distance is accurate.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, the present invention is a device for quickly drilling holes in rail tracks. It comprises a base 1 and two brackets 2, which are mounted parallel to and perpendicular to the base 1. Triangular reinforcement ribs 3 are provided between the brackets 2 and the base 1. A connecting plate 4 is provided between the ends of the two brackets 2 to securely connect the two brackets 2. The top edge of one bracket 2 is pivotally connected to one end of a positioning plate 5, with a protrusion on the other end of the positioning plate 5 mating with a groove in the other bracket 2. Punching blocks 8 are fixed to the two brackets 2 in front of the positioning plate 5. These punching blocks 8 are provided with drill holes 11 for passing a drill bit from a vertical drilling machine when drilling holes in the rail tracks. Below the punching blocks 8, the brackets 2 have holes for a clamping block 12. The clamping block 12 is connected to the telescopic rod of a pneumatic cylinder 7, which is secured to the base 1 via a pneumatic cylinder support frame 6. Below the clamping block 12, a rail support block 9 is provided on the base 1 to provide support for the rail to be cut. In order to facilitate the installation of the present invention on a vertical drilling machine, a drilling machine fixing hole 10 is opened on the bottom plate, and the present invention can be fixed to the vertical drilling machine by bolts.

[0015] When the utility model is in use, the utility model is first fixed to the vertical drilling machine by bolts so that the drill bit of the vertical drilling machine can pass through the drill hole 11; then the positioning plate 5 is lowered so that the positioning plate 5 is stuck between the two brackets 2, and then the rail is placed between the brackets 2 on both sides so that one end of the rail is against the positioning plate 5, and the clamping block 12 is pushed by the pneumatic cylinder 7 to clamp the rail, and then the rail can be drilled.
