A plurality of groups of fixing grooves are formed on the outer side wall of the column body. Each group of fixing grooves includes four fixing grooves, and an annular groove is formed on the groove wall of each of the four fixing grooves in each group. A ring block is slidably connected in each of the four annular grooves in each group. The beneficial effects achieved by the present invention are as follows: When in use, first, the protective plate can be pulled outwards, so that the protective plate is disengaged from the snap connection with the adjacent protective plate, and the protective plate is released from the abutment with the upper protective plate. At this time, the protective plate can be pushed upwards to expose the area to be maintained. Then, the protective plate can be released, and the spring will push the ring block, and the ring block will pull the protective plate through the cooperation of the fixing rod, the fixing plate, the T-shaped chute and the T-shaped slider, so that the protective plate abuts against and is fixed to the upper protective plate, thus facilitating subsequent maintenance.

Description

Technical Field

[0001] The present invention relates to a drill pipe for a rotary drilling rig, and more particularly to a drill pipe for a rotary drilling rig that is convenient for maintenance, belonging to the technical field of drill pipes for drilling rigs. Background Art

A number of groups of fixing grooves are provided on the outer side wall of the column body. Each group of fixing grooves includes four fixing grooves, and a circular groove is provided on the groove wall of each of the four fixing grooves in each group. A circular block is slidably connected in each of the four circular grooves in each group. The inner rings of the four circular blocks in each group respectively penetrate and extend into the corresponding fixing grooves and are fixedly sleeved with a fixing rod. One side side wall of each of the four circular blocks in each group is fixedly connected with a spring. The ends of the four springs in each group away from the circular blocks respectively abut against the groove walls of the corresponding circular grooves, and one end of each of the four fixing rods in each group penetrates and extends out of the column body.

A T-shaped sliding groove is provided on the outer side wall of each of the two fixing plates in each group. A T-shaped sliding block is slidably connected in each of the two T-shaped sliding grooves in each group. One end of each of the two T-shaped sliding blocks in each group penetrates and extends out of the fixing plate and is jointly fixedly connected with a protection plate. When in use, first pull out the protection plate in the area to be maintained outward, and the protection plate will move outward until it disengages from abutting against the protection plate in the upper position, then push the protection plate upward until the area to be maintained is exposed. At this time, the protection plate can be released, and the spring will push the circular block at this time.

[0007] Preferably, a layer of anti-slip layer is fixedly connected to the side wall of each group of two protection plates close to the T-shaped slider.

[0008] Preferably, a support plate is fixedly connected to the side wall of each group of two protection plates at the position below the T-shaped slider.

[0009] Preferably, the lower ends of several support plates all extend downward to and abut against the adjacent protection plate.

[0010] Preferably, each group of four springs is respectively sleeved on the rod wall of the fixed rod at the corresponding annular groove position.

[0011] Preferably, several groups of the T-shaped chutes, T-shaped sliders and protection plates are all arranged vertically.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-5 , a rotary drill pipe that is convenient for maintenance includes a column body 1. A number of groups of fixing grooves 2 are provided on the outer side wall of the column body 1. Each group of fixing grooves 2 includes four fixing grooves 2, and an annular groove 3 is provided on the groove wall of each group of four fixing grooves 2. A ring block 4 is slidably connected in each group of four annular grooves 3. The inner rings of each group of four ring blocks 4 respectively penetrate and extend into the corresponding fixing grooves 2 and are fixedly sleeved with a fixing rod 5. One side side walls of each group of four ring blocks 4 are fixedly connected with a spring 6 respectively. One ends of each group of four springs 6 away from the ring block 4 abut against the groove walls of the corresponding annular grooves 3 respectively, and one ends of each group of four fixing rods 5 penetrate and extend out of the column body 1. One ends of each group of four fixing rods 5 located outside the column body 1 are jointly fixedly connected with two fixing plates 7. A T-shaped sliding groove 8 is provided on the outer side wall of each group of two fixing plates 7. A T-shaped sliding block 9 is slidably connected in each group of two T-shaped sliding grooves 8. One ends of each group of two T-shaped sliding blocks 9 penetrate and extend out of the fixing plate 7 and are jointly fixedly connected with a protective plate 10.

[0021] Wherein, a layer of anti-slip layer 11 is fixedly connected to the side walls of each group of two protective plates 10 close to the T-shaped sliding block 9.

[0022] Wherein, a support plate 12 is fixedly connected to the side walls of each group of two protective plates 10 at the position below the T-shaped sliding block 9.

[0023] Wherein, the lower ends of several support plates 12 all extend downward to and abut against the adjacent protective plate 10.

[0024] Wherein, each group of four springs 6 are respectively sleeved on the rod walls of the fixing rods 5 at the positions of the corresponding annular grooves 3.

[0025] Wherein, several groups of T-shaped sliding grooves 8, T-shaped sliding blocks 9 and protective plates 10 are all arranged vertically.

[0026] Working principle: When in use, first, the protection plate 10 of the area to be maintained can be pulled outwards. The protection plate 10 will move outwards until it disengages from the protection plate 10 in the upper position. Then, the protection plate 10 can be pushed upwards until the area to be maintained is exposed. At this time, the protection plate 10 can be released. At this time, the spring 6 will push the annular block 4, and the annular block 4 will drive the fixed rod 5 to move. The fixed rod 5 drives the fixing plate 7 to move synchronously. The fixing plate 7 pulls the protection plate 10 through the cooperation of the T-shaped chute 8 and the T-shaped slider 9. The protection plate 10 will be pulled to abut against the outer wall of the protection plate 10 in the upper position and is protected by the anti-slip layer 11 to prevent it from sliding downwards, so as to keep the area exposed for convenient maintenance.

[0027] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
