[0038] The present invention is described below with reference to specific embodiments, but is not intended to limit the present invention.

[0039] Example 1

[0040] like Figure 1-Figure 5As shown, in this embodiment, a directional drilling rig mast locking device is provided, including a fixing seat 1, a fixing groove 102 is provided on the rear side wall of the fixing seat 1, and a plurality of bolt holes are opened on the side wall of the fixing groove 102; two sliding frames 2 are symmetrically slidably connected to the front side wall of the fixing seat 1, and reinforcing ribs 203 for increasing the strength of the sliding frame 2 are fixedly connected to the side wall of the sliding frame 2; clamping blocks 3 are respectively installed on the two sliding frames 2, and the two clamping blocks 3 are provided with clamping grooves 301 for clamping the mast, and a plurality of rollers 8 are evenly distributed on the side walls of the clamping grooves 301; wherein, a mounting groove 201 is opened on the side wall of the sliding frame 2, and a mounting block 302 is fixed on the side wall of the clamping block 3; when the mounting block 302 is installed to the inside of the mounting groove 201, the clamping block 3 is fixed on the sliding frame 2.

[0041] The end of the fixed seat 1 is fixedly connected to an end cover 9 for blocking the end opening of the slide groove 101. After the slider 202 is inserted into the interior of the slide groove 101, the end cover 9 is fixed to the end of the fixed seat 1, which can confine the slider 202 inside the slide groove 101, that is, the sliding frame 2 can be confined on the fixed seat 1.

[0042] Clamping operation: When the mast needs to be clamped, place the mast in the clamping groove 301 of the two clamping blocks 3. Since multiple rollers 8 are evenly distributed on the side walls of the clamping groove 301, the rollers 8 can reduce the friction between the mast and the clamping groove 301, making the mast easier to lock and preventing the mast from moving.

[0043] Example 2

[0044] like Figure 3 and Figure 4 As shown, on the basis of Example 1, in order to realize the rapid replacement of the clamping block 3, the front end of the mounting groove 201 of this embodiment is an open entrance and exit, and the mounting block 302 is disassembled and assembled in the mounting groove 201 through the entrance and exit; a plurality of connecting rods 4 are fixed on the side wall of the mounting block 302 perpendicular to the front side of the fixed seat 1, and a connecting head 401 is provided at one end of each connecting rod 4 close to the fixed seat 1; a plurality of slide rails 5 are fixed on the front side of the fixed seat 1 along the sliding direction of the sliding frame 2, and the connecting head 401 is slidably connected to the slide rail 5, and the cross-section of the slide rail 5 is T-shaped, and a T-slot that matches the shape of the slide rail 5 is opened on the connecting head 401. When the connecting head 401 slides on the slide rail 5 through the T-slot, the connecting head 401 can only slide along the length direction of the slide rail 5.

[0045] like Figure 3 and Figure 5 As shown, in order to fix the connecting rod 4 to the mounting block 302, a socket 3021 is provided on the side wall of the mounting block 302, and the connecting rod 4 is inserted into the inside of the socket 3021. A fixing bolt 6 is provided on the side wall of the mounting block 302, and the threaded end of the fixing bolt 6 passes through the mounting block 302 and the connecting rod 4. Figure 5 As shown, through holes are opened on the side walls of the mounting block 302 and the connecting rod 4. When the connecting rod 4 is inserted into the socket 3021, the through hole on the connecting rod 4 is aligned with the through hole on the mounting block 302, and the threaded end of the fixing bolt 6 is engaged with a nut.

[0046] like Figure 2 and Figure 4 When the cam 302 is in the closed position, the cam 302 is in the closed position, and the cam 302 is in the closed position, so that the cam 302 is in the closed position and the cam 302 is in the closed position.

[0047] During use, the sliding frame 2 is always in a non-end position of the fixed base 1. In this way, it can be ensured that the connecting head 401 is always on the slide rail 5 during use to prevent the clamping block 3 from separating from the sliding frame 2.

[0048] Similarly, when the clamping block 3 needs to be removed, the sliding frame 2 is slid to the end of the fixed seat 1 again. At this time, the connecting head 401 is disengaged from the slide rail 5. In this state, the clamping block 3 and the mounting block 302 are pulled together, and the mounting block 302 can be pulled out of the mounting groove 201, so that the clamping block 3 can be quickly removed from the sliding frame 2.

[0049] Example 3

[0050] like Figure 3 As shown, based on the above embodiment, in this embodiment, in order to enable the sliding frame 2 to slide on the front side of the fixed base 1, a slider 202 is provided on the side wall of the sliding frame 2, and a sliding groove 101 for the slider 202 to slide is opened on the front side of the fixed base 1. In addition, an oil cylinder 7 is fixedly installed on the side wall of the fixed base 1, and the output shaft end of the oil cylinder 7 is connected to the side wall of the sliding frame 2;

[0051] When the oil cylinder 7 is activated, the output shaft of the oil cylinder 7 moves telescopically to drive the sliding frame 2 to slide on the front side of the fixed seat 1.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
