DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the content of the utility model easier to be clearly understood, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. The same reference numerals are used for the same components. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0018] Such as Figure 1-2As shown in the figure, in this embodiment, a material pushing device for a catwalk of an oil drilling rig is provided, including: a base 1, the base 1 is placed horizontally and can be connected to an inclined track during use. The two sides of the top of the base 1 are connected to a support plate 2 through connecting bent plates 3. The setting of the connecting bent plates 3 disperses the pressure on the top of the support plate 2 and reduces the probability of device failure; several limit posts 4 are arranged along the axial direction on the top of the support plate 2. The limit posts 4 provide direction guidance for the drill pipe receiving frame 18. A stop iron 5 is arranged on one side of the limit posts 4, and a connecting column 6 is arranged on the opposite side of the stop iron 5. The working dimensions of the two stop irons 5 are smaller than the working dimensions of the support plate 2 and are located at the middle position of the top of the receiving plate 10; a drill feeding device body 7 is arranged on the opposite sides of the support plate 2. The width of the drill feeding device body 7 is smaller than the width of the opposite sides of the connecting bent plates 3. The drill feeding device body 7 is slidably connected to the base 1, and sliding grooves 8 are symmetrically opened at the top. During operation, the drill feeding device body 7 slides from the track onto the upper surface of the base 1 and stops sliding when its bottom is parallel to the base 1; the sliding grooves 8 are movably connected to a material pushing trolley 9. A receiving plate 10 is arranged on one side of the material pushing trolley 9. Clamping components 11 are arranged on both sides of the receiving plate 10. The clamping components 11 can firmly grasp the drill pipe, preventing slipping and loosening during the pushing process. And because various corrosive media and abrasive substances will be encountered in oil drilling operations, the surface of the clamping components 11 has good wear resistance and corrosion resistance to extend the service life. The clamping components 11 are located on the top of the support plate 2 and are slidably connected to the support plate 2.

[0019] A groove 14 is opened at the top of the material pushing trolley. A connecting frame 16 is arranged at the middle position of the top of the groove 14, and a hydraulic motor 15 is arranged on the bottom wall. The hydraulic motor 15 has large thrust and torque and can adapt to heavy loads and harsh working environments; a transmission system 12 is arranged at the bottom of the material pushing trolley 9. Wheels 13 are movably connected to the four corners of the transmission system 12. The transmission system 12 is connected to the hydraulic motor 15. By starting the hydraulic motor 15, the hydraulic motor 15 drives the wheels 13 to move through the transmission system 12, thereby pushing the drill pipe in the clamping components 11; a receiving plate 10 is arranged on the side of the material pushing trolley 9 away from the hydraulic motor 15; extension rods 17 are arranged on both sides of the receiving plate 10. Clamping components 11 are arranged on the sides of the extension rods 17 away from the material pushing trolley 9.

[0020] The grasping and buckling component 11 includes: a drill receiving frame 18, which is slidably connected to the support plate 2. The drill receiving frame 18 is open on both sides, and one side is connected to the extension rod 17. A rotating shaft 19 is provided through the opposite sides of the drill receiving frame 18. Sleeve shafts 20 are sleeved on both sides of the rotating shaft 19. A grasping buckle 21 is provided on one side of the sleeve shaft 20. The working dimension of the stop iron 5 is smaller than the working dimension of the drill receiving frame 18, and the height is lower than the height from the extension rod 17 to the bottom of the drill receiving frame 18. During operation, when the drill pipe enters the interior of the drill receiving frame 18, one end of the drill pipe abuts against the rotating shaft 19. At this time, the grasping buckle 21 firmly fixes both sides of the drill pipe. As the feeding trolley 9 moves, when the drill receiving frame 18 passes through the stop iron 5, the rotating shaft 19 contacts the connecting column 6. At this time, the rotating shaft 19 collides with the connecting column 6, and the grasping buckle 21 rotates upward to release the drill pipe fixed by it.

[0021] The above are only the preferred embodiments of the utility model patent, and are not intended to limit the utility model patent. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the utility model patent shall be included in the protection scope of the utility model patent.
