AI Technical Summary
During the working process of the horizontal directional drilling rig, the threaded connection between the drill rod and the gear box spindle is frequently raised and shackled, causing the gear box to move forward and backward, which is easy to destroy the thread. After the drill rod is added, the gear box needs to remain relatively fixed to the cart, which has the problem of protecting the threaded buckle.
A threaded buckle protection device including components such as trolleys, cylindrical tracks, gear boxes, rotary motors, spindles, locking cylinders, etc. is designed. The rotating motor drives the spindle and the drill rod to form a spiral transmission, realize the upper buckle or shackle, and keep the gear box relatively fixed to the trolley by locking the oil cylinder to protect the thread.
It effectively protects the threads of the drill rod and the gear box spindle, avoids the damage of the threads, and ensures that the gear box and the trolley are relatively fixed after the drill rod is added, improving the working efficiency and reliability of the drill rig.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thread buckle protection devices, in particular to a thread buckle protection device for a drill rod of a horizontal directional drilling rig. Background Art
[0002] When the horizontal directional drilling rig is working, the drill rod is connected to the main shaft of the gear box through threads. The main shaft of the gear box rotates and drills forward with the trolley. Due to the limited length of a single drill rod, the actual length of the project often requires dozens of drill rods to be connected end to end to increase the drilling length. In the process of adding drill rods, it is necessary to frequently make and break the threaded connection between the drill rod and the main shaft of the gear box. At this time, the drill rod buried in the soil is fixed. When making and breaking the thread, the drill rod and the main shaft of the gear box form a spiral transmission, forcing the gear box to move forward and backward. If the gear box is fixed on the trolley, the thread will be damaged. In addition, when the drill rod is added, the gear box needs to remain relatively fixed with the trolley when the trolley moves forward.
[0003] Therefore, in view of the above problems, a horizontal directional drilling rig drill rod thread buckle protection device is proposed. Utility Model Content
[0004] The utility model aims to provide a drill rod thread buckle protection device for a horizontal directional drilling rig, comprising a trolley, a cylindrical track is arranged on the upper right side of the trolley, the upper part of the cylindrical track is slidably connected to the bottom of a gear box through a shaft sleeve, a rotary motor is arranged on the upper part of the gear box, a main shaft is arranged on the lower part of the gear box, a locking cylinder is arranged on the lower left side of the gear box, the left side of the locking cylinder is bolted to the locking cylinder seat, the cylinder rod on the right side of the locking cylinder is in contact with the gear box, a push-pull motor is arranged on the left side of the locking cylinder seat, and the push-pull motor is bolted to the upper left side of the trolley.
[0005] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0006] The utility model connects the main shaft with the drill rod, and the drill rod is fixed in the ground. When the rotary motor drives the main shaft to rotate through the gear box, the main shaft and the drill rod form a spiral transmission, thereby realizing the action of making or breaking the thread. At this time, since the drill rod is fixed, the spiral transmission forces the gear box to move forward or backward on the cylindrical track, which is convenient for protecting the threaded buckle.
[0007] The utility model provides a locking oil cylinder, and the cylinder rod of the locking oil cylinder extends out to abut against the gear box and the left side of the cylindrical track, so that the gear box and the trolley are kept relatively fixed. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The reference numerals and names in the figures are as follows:
[0010] 1. Spindle; 2. Rotating motor; 3. Gearbox; 4. Push-pull motor; 5. Trolley; 6. Locking cylinder seat; 7. Locking cylinder; 8. Cylindrical track. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] As attached Figure 1 As shown, the utility model provides a drill pipe thread buckle protection device for a horizontal directional drilling rig, including a trolley 5, a cylindrical track 8 is arranged on the upper right side of the trolley 5, and the upper part of the cylindrical track 8 is slidably connected to the bottom of the gear box 3 through a shaft sleeve, a rotary motor 2 is arranged above the gear box 3, a main shaft 1 is arranged below the gear box 3, and the rotary motor 2 is connected to the main shaft 1 through a gear set, a locking cylinder 7 is arranged on the lower left side of the gear box 3, and the left side of the locking cylinder 7 is bolted to the locking cylinder seat 6, and the cylinder rod on the right side of the locking cylinder 7 is in contact with the gear box 3, and a push-pull motor 4 is arranged on the left side of the locking cylinder seat 6, and the push-pull motor 4 is bolted to the upper left side of the trolley 5.
[0013] Specifically, the main shaft 1 is connected to the gear box 3 by bolts.
[0014] Specifically, the rotary motor 2 is connected to the gear box 3 by bolts.
[0015] Specifically, the push-pull motor 4 drives the trolley 5 to move forward and backward through a gear rack mechanism.
[0016] Working principle: When drilling, the rod of the locking cylinder 7 extends to press against the gear box 3 and the left side of the cylindrical track 8, so that the gear box 3 and the trolley 5 remain relatively fixed. At this time, the rotary motor 2 drives the main shaft 1 to rotate through the gear set in the gear box 3, and the push-pull motor 4 drives the trolley 5 forward through the gear rack mechanism.
[0017] When the work of adding drill rods is performed, the push-pull motor 4 stops moving, the trolley 5 is fixed on the drilling rig, and the cylinder rod of the locking cylinder 7 is retracted, so that the gear box 3 can slide freely on the cylindrical track 8, connecting the main shaft 1 with the drill rod, and the drill rod is fixed in the ground. When the rotary motor 2 rotates the main shaft 1 through the gear box 3, the main shaft 1 and the drill rod form a spiral transmission, thereby realizing the action of making or breaking the thread. At this time, since the drill rod is fixed, the spiral transmission forces the gear box 3 to move forward or backward on the cylindrical track 8, thereby protecting the threaded buckle.
