The existing method of placing it is generally to use a drilling rig to hang the drill rod, and put the front end of the drill rod with a male thread into the slide of the drill rod box. The drill rod has a certain inclination, and the drill rod slides forward along the slide of the drill rod box. The inclination of the drill rod and the slide of the drill rod box gradually decreases. When the male thread end of the drill rod reaches the bending plate at the front end of the slide of the drill rod box, the drill rod automatically slides into the drill rod box.

[0004] The above method has the problem that the front end of the drill rod is in long-term friction with the slideway, which may cause the drill rod to be scrapped when the front end of the drill rod is worn to a certain extent. At the same time, there is a problem that the front end of the drill rod is easily stuck inside the slideway; therefore, it does not meet the existing needs, and a drilling rig drill rod box drill rod pulley is proposed.

[0019] 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.

[0020] In order to solve the problem that the front end of the drill pipe is worn to a certain extent due to long-term friction with the slideway, the drill pipe will be scrapped, and the front end of the drill pipe is easily stuck inside the slideway. Figure 1-4 , the utility model provides an embodiment: a drilling rig drill rod box drill rod pulley, including a drill rod 1, and also including a pulley frame 4, the pulley frame 4 is located at one end of the drill rod 1, a slideway 2 is arranged below the drill rod 1, a drill rod box 3 is arranged below the slideway 2, the pulley frame 4 is installed on the slideway 2, the pulley frame 4 includes a lower side plate 401, an upper plate 402, an upper side plate 403, a stopper 404 and a fixed plate 405, the lower side plate 401 and the fixed plate 405 are installed below the upper plate 402, the upper side plate 403 and the stopper 404 are installed above the upper plate 402, the fixed plate 405 is located inside the slideway 2, the stopper 404 is a cylindrical structure, the curved surface of the stopper 404 is connected to the upper surface of the upper plate 402, the slideway 2 is a U-shaped straight line structure, a bending plate 201 is arranged at one end of the slideway 2, and the slideway 2 is obliquely installed above the drill rod box 3.

[0021] The lower side plate 401, the upper plate 402, the upper side plate 403 and the fixed plate 405 are all rectangular structures. The upper plate 402 is located above the slide 2, the upper plate 402 is parallel to the bottom surface of the slide 2, the upper side plate 403 is perpendicular to the top of the upper plate 402, and the lower side plate 401 and the fixed plate 405 are perpendicular to the bottom of the upper plate 402; a first roller 4011 is provided on the side of the lower side plate 401, a second roller 4021 is provided on the bottom of the upper plate 402, and a third roller 4051 is provided on the side of the fixed plate 405.

[0022] The upper plate 402 supports the front end of the drill rod 1, so that the front end of the drill rod 1 does not need to be in direct contact with the slide 2. The upper side plate 403 and the stopper 404 are used to limit the position of the front end of the drill rod 1 on the upper plate 402. At the same time, when the front end of the drill rod 1 is close to the bending plate 201 and the drill rod 1 is about to slide into the drill rod box 3, an angle is formed between the drill rod 1 and the upper plate 402, and a gap appears, so that a part of the front end of the drill rod 1 is higher than the stopper 404. The bending plate 201 blocks the front end of the drill rod 1, thereby changing the position of the drill rod 1, and the drill rod 1 bypasses the stopper 404 and slides into the drill rod box 3.

[0023] A pulley frame 4 is installed on the slide 2, and rollers are installed on the pulley frame 4 to form a pulley. The pulley can slide arbitrarily along the slide 2. The front end of the drill rod 1 is located on the pulley. The front end of the drill rod 1 moves in the slide 2 against the pulley, so that the front end of the drill rod 1 does not need to directly contact the slide 2, thereby avoiding the wear caused by the front end of the drill rod 1 sliding inside the slide 2, and further extending the service life of the drill rod 1.

[0024] At least two first rollers 4011 are provided, and the first rollers 4011 are connected to the shaft of the lower side plate 401, and are located below the slide 2. The first rollers 4011 contact the outer bottom surface of the slide 2 when rolling, and the first rollers 4011 prevent the pulley from escaping from the slide 2, and also prevent the pulley from swinging left and right.

[0025] At least four second rollers 4021 are provided, and the second rollers 4021 are connected to the axis of the upper plate 402. The second rollers 4021 and the third rollers 4051 are located inside the slide 2, and the second rollers 4021 are in contact with the inner wall of the slide 2. The second rollers 4021 ensure that the pulley can move smoothly in the slide 2, and at the same time limit the amplitude of the left and right swing of the pulley when moving, thereby further improving the smoothness of the sliding of the pulley.

[0026] At least two third rollers 4051 are provided, and the third rollers 4051 are axially connected to the fixed plate 405, and the third rollers 4051 are in contact with the inner bottom surface of the slideway 2. The third rollers 4051 support the weight of the pulley and the drill rod 1, and drive the drill rod 1 to slide along the slideway 2. The rolling friction of the rollers is much lower than the sliding friction, so that the pulley can slide smoothly along the slideway 2, so that the drill rod 1 will not get stuck when moving inside the slideway 2, and the efficiency of putting the drill rod 1 into the drill rod box 3 is further improved.

[0027] Working principle: The front end of the drill rod 1 is placed on the upper plate 402 of the pulley, and the front end of the drill rod 1 moves against the pulley in the slideway 2. When the front end of the drill rod 1 touches the bending plate 201, the drill rod 1 slides into the interior of the drill rod box 3, so that the front end of the drill rod 1 does not need to directly contact the slideway 2, thereby avoiding wear on the front end of the drill rod 1 and extending the service life of the drill rod 1.
