Description

Technical Field

[0001] The utility model relates to the technical field of drill rod processing, in particular to a drill rod tube blank sawing and pushing device. Background Art

[0002] Spiral drill rods, triangular drill rods, and round drill rods used in coal mines are all manufactured from drill pipe billets through processes such as cutting, machining, shaping, upsetting, welding, and heat treatment. The raw material, typically tens of meters long, requires cutting using a gantry saw. During production, several platforms are typically installed on the inlet side of the gantry saw to horizontally support the drill pipe billets. The platform is essentially a frame with multiple rollers arranged horizontally within it. The drill pipe billets are then placed flat on the rollers. A pull handle is then attached to the blanking end of the drill pipe billet. Each time a cut is made, the pull handle is manually pulled to push the drill pipe billet into the gantry saw, completing the cut. The problems currently encountered in production with this processing method are: the drill pipe blank is very heavy, and even with a roller structure, it takes a lot of effort to pull it each time. In addition, the pulling handle connected to the drill pipe blank blanking tube needs to be removed after each sawing and blanking action is completed, and then reinstalled on the new blanking end of the drill pipe blank. The disassembly and assembly are cumbersome and the efficiency is very low. In addition, each time the drill pipe blank is pulled, it is necessary to prevent the drill pipe blank from deflecting. Otherwise, once it deflects, the blanking accuracy will be affected, resulting in waste of raw materials. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to propose a drill pipe blank sawing and pushing device. On the basis of the existing platform frame structure, a pushing roller driven by a drive motor is added, which can actively push the drill pipe blank forward for unloading. The pressure roller and roller sleeve can assist in pushing and unloading the drill pipe blank, effectively preventing the drill pipe blank from deflecting.

[0004] The technical solutions adopted by the present invention to solve the above problems are as follows:

[0005] The drill rod blank sawing and pushing device includes a drill rod pushing frame and a conveying roller arranged on the drill rod pushing frame. The drill rod pushing frame is also provided with a pushing roller. A driving motor for driving the pushing roller to rotate is provided on one side of the drill rod pushing frame. A pressure roller assembly for assisting the pushing of the drill rod is provided on the top of the drill rod pushing frame, which is located on the upper side of the pushing roller. Anti-deflection components for preventing the drill rod from deflecting during pushing are provided at both ends of the top of the drill rod pushing frame.

[0006] As a preferred technical solution, a plurality of anti-slip ridges are evenly distributed on the circumferential surface of the pushing roller along its length direction.

[0007] As a preferred technical solution, the anti-skid ridges are all made of flexible material, and the surface of each anti-skid ridge is provided with spherical anti-skid protrusions.

[0008] As a preferred technical solution, the pressure roller assembly includes a stand, a crossbeam, a roller frame and a pressure roller. There are two stands, which are respectively arranged on both sides of the top of the drill rod pushing frame. The crossbeam is horizontally mounted on the top of the two stands. The roller frame is vertically arranged at the bottom center of the crossbeam. The pressure roller is arranged on the roller frame and is located on the upper side of the pushing roller. The gap between the pressure roller and the pushing roller is a pushing gap for the drill rod to pass through.

[0009] As a preferred technical solution, the roller frame includes a U-shaped frame for assembling the pressure roller and a screw rod vertically arranged at the top center of the U-shaped frame. The top end of the screw rod is vertically passed through the crossbeam and is fixed by adjusting nuts located on the upper and lower sides of the crossbeam.

[0010] As a preferred technical solution, the anti-deviation assembly includes two vertically arranged vertical shafts and roller sleeves respectively sleeved on the vertical shafts, and the gap between the two roller sleeves is a pushing gap for the drill rod to pass through.

[0011] As a preferred technical solution, a limiting ring for supporting the roller sleeve is provided at the bottom of the vertical shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The setting of the pushing roller can realize the automatic pushing and unloading of the drill pipe blank, without the need for manual pulling, which greatly improves the production efficiency; in addition, the pressing roller assembly presses against the drill pipe blank on the upper side of the drill pipe blank, which can effectively avoid the problem of the drill pipe blank slipping between the pushing roller and the pushing roller during the pushing process due to its excessive mass, thereby ensuring the effective pushing of the pushing roller; finally, the anti-deflection assembly is clamped on both sides of the drill pipe blank, which can effectively prevent the drill pipe blank from being skewed during the pushing process, thereby effectively solving the problems existing in the prior art.

[0016] The following is a relatively detailed and specific description of the specific implementation methods of the present invention in conjunction with the accompanying drawings. The parts that are not detailed are all contents that should be understood and mastered by those skilled in the art. This embodiment is only an illustrative description of the specific implementation methods of the present invention, and is not a limitation on the technical solution claimed to be protected by the present invention.

[0017] like Figure 1 As shown, this embodiment discloses a drill rod blank sawing and pushing device, comprising a drill rod pushing frame 1 and a conveying roller 2 arranged on the drill rod pushing frame 1. The drill rod pushing frame 1 is actually the platform frame described in the background technology, and its main body is a rectangular frame. A plurality of conveying rollers 2 are evenly arranged on the top surface of the frame. A pushing roller 3 is also provided on the drill rod pushing frame 1. A driving motor 4 for driving the pushing roller 3 to rotate is provided on one side of the drill rod pushing frame 1. A pressure roller assembly for assisting drill rod pushing is provided on the top of the drill rod pushing frame 1, located on the upper side of the pushing roller 3. Anti-deflection components for preventing drill rod deflection during pushing are provided at both ends of the top of the drill rod pushing frame 1.

[0018] The pressure roller assembly includes a stand 5, a crossbeam 6, a roller frame 7 and a pressure roller 8. There are two stands 5, which are respectively arranged on both sides of the top of the drill rod pushing frame 1. The crossbeam 6 is horizontally mounted on the top of the two stands 5. The roller frame 7 is vertically arranged at the bottom center of the crossbeam 6. The pressure roller 8 is arranged on the roller frame 7 and is located on the upper side of the pushing roller 3. The gap between the pressure roller 8 and the pushing roller 3 is a pushing gap for the drill rod to pass through.

[0019] The anti-deviation assembly includes two vertically arranged vertical shafts 9 and roller sleeves 10 respectively sleeved on the vertical shafts 9. A limiting ring 91 for supporting the roller sleeves 10 is provided at the bottom of the vertical shaft 9. The gap between the two roller sleeves 10 is a pushing gap for the drill rod to pass through.

[0020] In this embodiment, a number of anti-skid ridges 31 are evenly distributed on the circumferential surface of the pushing roller 3 along its length direction. At the same time, the anti-skid ridges 31 are all made of flexible material, and soft rubber is used in practice, and the surface of each anti-skid ridge 31 is provided with spherical anti-skid protrusions. This structure is mainly used to increase the contact friction between the pushing roller 3 and the drill pipe blank, so as to avoid slipping as much as possible during the pushing process of the drill pipe blank.

[0021] In this embodiment, the roller frame 7 comprises a U-shaped frame for assembling the pressure roller 8 and a screw 71 vertically disposed at the center of the top of the U-shaped frame. The top end of the screw 71 is vertically inserted into the crossbeam 6 and secured by adjustment nuts 72 located on the upper and lower sides of the crossbeam 6. The crossbeam 6 has an opening in the center for the screw 71 to pass through. The screw 71 can move freely up and down within the opening of the crossbeam 6, thereby adjusting the size of the pushing gap between the pressure roller 8 and the pushing roller 3. This is mainly to accommodate the pushing of drill pipe blanks of different specifications and models.

[0022] In the working state, because the length of the drill pipe blank is very long, the equipment of the present application still needs to be used in conjunction with the existing platform frame. It is only necessary to place the equipment of the present application at the end closest to the gantry sawing machine, and generally only one equipment of the present application is used. Of course, according to needs, multiple equipment of the present application can be set up at intervals in the platform frame, so that the pushing stability is higher.

[0023] During use, after placing the drill pipe blank on the drill pipe pushing frame 1, the drill pipe blank is clamped and fixed on the same axis through the anti-deflection components at both ends to prevent the drill pipe blank from deflecting. After adjusting the pressure roller assembly to the optimal position, the drive motor 4 is started and the drill pipe blank can be automatically pushed.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
