The left and right sides of the outer end of the seat 99 are configured to be connected to the adjusting screw 91 in contact with the screw 91. The hook 98 is configured to be connected to the winding rope 7 in a hooking manner.

[0086] By moving the hook seat 9, a support connection point is formed for the winding rope 7, the support beam 8, and the adjusting screw 91. The hook part 98 is connected to the winding rope 7, the seat part 99 and the receiving groove IV 97 are connected to the support beam 8, and the seat part 99 and the receiving hole VI 96 are connected to the adjusting screw 91. Its technical purpose is to serve as a support carrier for the winding rope 7.

[0087] In this embodiment, the seat 99 is configured as a strip and the hook 98 is configured as an L-shaped rod, the receiving groove IV 97 is configured as an annular groove and the receiving hole VI 96 is configured as a hole.

[0088] Its technical purpose is to achieve hook support for the winding rope 7.

[0089] In this embodiment, a receiving groove V912 is provided at the inner end of the screw part II911 of the adjusting screw 91, and the inner end of the screw part II911 is configured to be connected through the movable hook seat 9. The inner peripheral side of the receiving groove V912 is configured to be connected in contact with the movable hook seat 9, and the outer end of the screw part II911 is configured to be connected in a threaded manner with the support beam 8.

[0090] By adjusting the screw 91, a support connection point is formed for the support beam 8 and the movable hook seat 9. The screw part II 911 is connected to the support beam 8, and the screw part II 911 and the receiving groove V 912 are connected to the movable hook seat 9. Its technical purpose is to serve as a component that drives the movable hook seat 9 to move in the support beam 8.

[0091] In this embodiment, the screw part II 911 is configured as a light column bolt and the receiving groove V 912 is configured as an annular groove.

[0092] Its technical objective is to enable the movable hook seat 9 to move within the support beam 8 via the movement of the screw thread.

[0093] In this embodiment, the base frame 2, support screw 5, clamping nut 6, winding rope 7, support beam 8, movable hook seat 9, and adjusting screw 91 are arranged in a winding and fixing manner. One support screw 5, one clamping nut 6, one winding rope 7, one support beam 8, one movable hook seat 9, and one adjusting screw 91 are arranged to form a set of winding and fixing components. Two sets of winding and fixing components are arranged on the base frame 2. Screw part I 51 is respectively connected to cylinder part 21 and receiving hole I 24. Screw part II 911 is respectively connected to receiving hole IV 82 and receiving hole VI 96. Receiving groove V 912 is connected to base part 99. Base part 99 is connected to receiving hole V 83. Receiving groove IV 97 is connected to beam part 81.

[0094] The method of use in this embodiment is as follows: When the cylinder 21 is placed on the drill rod of the tracked tunnel drilling rig, the receiving groove I22 is clamped onto the drill rod of the tracked tunnel drilling rig, and the screw part I51 moves in the receiving hole I24. The position of one end of the winding rope 7 on the cylinder 21 is adjusted. After the position of the other end of the winding rope 7 on the cylinder 21 is adjusted, the clamping nut 6 is rotated on the screw part I51, so that the flange of the screw part I51 and the inner end face of the clamping nut 6 are... The action is applied to the cylinder 21 to wrap the winding rope 7 around the drill rod of the tracked tunnel drilling rig. After the winding rope 7 is wrapped around the drill rod, one end of the winding rope 7 is placed inside the receiving groove Ⅲ 84, and the loop of the winding rope 7 is hooked onto the hook 98. This causes the screw part Ⅱ 911 to rotate in the receiving hole Ⅳ 82, causing the seat part 99 to move inward in the receiving hole Ⅴ 83, thus tautling the winding rope 7. This allows the seat 2 to be installed on the drill rod of the tracked tunnel drilling rig.

[0095] When it is necessary to separate the base 2 from the drill rod of the tracked tunnel drilling rig, the screw part II 911 is rotated in the opposite direction in the receiving hole IV 82, the base part 99 is moved outward in the receiving hole V 83, the winding rope 7 is in a slack state, the loop part of the winding rope 7 is separated from the hook part 98, the winding rope 7 is wound in the opposite direction on the drill rod of the tracked tunnel drilling rig, and the winding rope 7 is separated from the drill rod of the tracked tunnel drilling rig.

[0096] In verifying this utility model, the inventors abandoned the existing technical features that all use angle sensors to adjust the horizontal orientation and vertical inclination of the drill rod. Instead, they first proposed a technical feature that uses the comprehensive signal measured from the drill rod of the tracked tunnel drilling rig as the adjustment reference standard. This resulted in the first technical effect: using the comprehensive signal as the adjustment reference standard for the horizontal orientation and vertical inclination of the drill rod of the tracked tunnel drilling rig, improving the adjustment efficiency of the drill rod. The second technical effect: enabling the acquisition of the comprehensive signal by the hole positioning instrument 1, improving the adjustment effect of the drill rod. The third technical effect: enabling the positioning connection between the receiving groove I22 of the base 2 and the drill rod of the tracked tunnel drilling rig, improving the positioning efficiency of the hole positioning instrument 1. The installation consistency of the drill rod of the tracked tunnel drilling rig has achieved the fourth technical effect: the tightening screw 3 and pressure pad 4 are used to press and fix the hole positioning device 1 on the base frame 2, optimizing the installation operation of the hole positioning device 1. The fifth technical effect: the dual-part fixed connection of the drill rod of the tracked tunnel drilling rig by the winding rope 7, support beam 8, moving hook seat 9 and adjusting screw 91 is achieved, improving the stability of the base frame 2 in the installation of the drill rod of the tracked tunnel drilling rig. The sixth technical effect: the end of the winding rope 7 is installed on the base frame 2 by the support screw 5 and clamping nut 6, and the installation position of the end of the winding rope 7 on the base frame 2 is adjusted, optimizing the winding position of the winding rope 7 and the drill rod of the tracked tunnel drilling rig.

[0097] In the second embodiment of this utility model, the base 2 and the hole positioning instrument 1 are connected to each other in a manner that uses the comprehensive signal of the drill rod of the tracked tunnel drilling rig as the adjustment reference standard.

[0098] In this embodiment, the base frame 2 is connected to the hole positioning device 1 in a manner that automatically positions and installs the drill rod of the tracked tunnel drilling rig in a V-shaped groove.

[0099] In this embodiment, a first accessory device is also included and disposed between the base 2 and the hole positioning device 1. The first accessory device is configured to include a tightening screw 3 and a pressure pad 4.

[0100] The second embodiment of this utility model is based on the first embodiment.

[0101] This utility model has the following features:

[0102] 1. Due to the design of the mounting frame 2 and the hole positioning device 1, the hole positioning device 1 provides data signals for adjusting the horizontal orientation and vertical inclination of the drill rod. The mounting frame 2 enables automatic positioning and installation of the drill rod of the crawler tunnel drilling rig in a V-shaped groove. It realizes the use of the comprehensive signal of the drill rod of the crawler tunnel drilling rig as the adjustment reference standard, and solves the technical problem of using angle sensors to adjust the horizontal orientation and vertical inclination of the drill rod. Therefore, it improves the adjustment effect of the drill rod of the crawler tunnel drilling rig.

[0103] 2. Due to the design of the tightening screw 3 and pressure pad 4, the hole positioning instrument 1 is clamped and fixed in the base 2.

[0104] 3. Due to the design of support screw 5, clamping nut 6, winding rope 7, support beam 8, movable hook seat 9 and adjusting screw 91, the seat 2 can be fixed by double-end winding on the drill rod of the crawler tunnel drilling rig.
