Description

Technical Field

[0001] The utility model relates to the technical field of the repair of steel drills for calcium carbide furnaces, and is an electric control drill gripper aligning machine. Background Art

[0002] The production process flow of a calcium carbide furnace is as follows: after mixing lime carbide and coke, in a certain proportion, it is transported to 12 small bins through the top floor batching station, the feeding belt and the ring feeder. After entering the furnace by the self-weight of the furnace charge, calcium carbide is smelted by using electrodes, the smelting temperature is 1800°C to 2200°C, and the smelting lasts for 30 minutes to 40 minutes for tapping operation. The tapping system of the calcium carbide furnace consists of three independent tapping holes. Each shift is 8 hours, and the three tapping holes are alternately tapped every 1 hour, and the tapping time is 20 minutes to 30 minutes. In front of the tapping hole, there are an intelligent robot, a tapping track, a tapping hood, a fire door, a tapping trolley, a hoist, a calcium carbide pot, a cooling circulating water pipe, etc.; the intelligent robot has an integrated tool rack, including 5 long steel drills and 4 short drill rods and a hole burning device. The function of the steel drill is to extend into the tapping hole to drain the high-temperature liquid calcium carbide to the outer opening of the tapping hole, flow through the tapping tongue and enter the calcium carbide pot for cooling. After cooling in front of the furnace for 40 minutes, it is towed to the cooling workshop by a hoist for secondary cooling. After cooling for 2.5 to 3 hours, a double-girder crane is used for clamping and lifting operations.

[0003] During the tapping process of the intelligent robot, when the tapping hole is just opened, the calcium carbide in the calcium carbide furnace has a high temperature of 2300°C. After the liquid calcium carbide flows to the outer opening, there is a temperature drop. The contact time between the steel drill and the hot calcium carbide is 30 minutes per furnace, and the steel drill needs to reciprocate continuously in the tapping hole for 12 times. Therefore, after the steel drill is burned and damaged, it becomes shorter, the whole body is severely deformed or deformed, and it cannot reach the function of dredging the tapping hole, so the steel drill needs to be replaced and aligned. The operation of replacing the steel drill requires 3 people to manually lift 35 kg, with a large labor intensity, and there is a risk of bruising during the operation. Moreover, the alignment and butt welding time of the steel drill requires 60 minutes, and the work efficiency is low. Summary of the Invention

[0004] The utility model provides an electric control drill gripper aligning machine, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems of large labor intensity and the risk of bruising during the operation existing in the existing steel drill alignment.

[0005] The technical solution of the utility model is realized by the following measures: An electric control grab drill rod aligning machine, including a workbench, an aligning oil cylinder, an aligning block, a lifting frame, a lifting mechanism and at least two aligning clamps.

An inlet whose lower part communicates with the rear part of the through hole is provided on the upper side of the aligning clamp corresponding to the position of the through hole. A mounting hole that penetrates through in the front and rear is provided at the rear center of the rear fixing plate. An aligning oil cylinder is installed on the upper side of the rear part of the workbench corresponding to the position of the mounting hole. The front end of the piston rod of the aligning oil cylinder passes through the mounting hole and is fixedly installed with an aligning block. An arc-shaped aligning groove that penetrates through in the left and right and opens forward is provided on the front side of the aligning block. A lifting frame is provided at the rear side of the workbench, and a lifting mechanism capable of moving back and forth is provided on the upper part of the lifting frame.

There are two aligning clamps. The front part of one aligning clamp is installed in the front adjusting groove on the left side of the through hole, and the front part of the other aligning clamp is installed in the front adjusting groove on the right side of the through hole.

[0016] In the utility model, for the convenience of description, the description of the relative position relationship of each component is carried out according to the layout mode of the attached drawings of the specification, such as: the position relationships of front, rear, upper, lower, left, right, etc. are determined according to the layout direction of the attached drawings of the specification. Figure 1 The layout direction of the attached drawings of the specification. Figure 1 is used to determine.

[0017] The following further describes the utility model in conjunction with the embodiments and the drawings:

[0018] Embodiment 1: As shown in the appendix Figure 1 , 2As shown in the figure, the electric control grab drill rod aligning machine includes a workbench 1, an aligning oil cylinder 2, an aligning block 3, a lifting frame 4, a lifting mechanism and at least two aligning clamps 5. The front fixing plate 6 and the rear fixing plate 7 are fixedly installed at intervals before and after on the upper side of the workbench 1. At least two front adjusting grooves 8 which are upwardly open and penetrate through in the front-rear direction are provided at intervals on the rear side of the front fixing plate 6. At the front side of the rear fixing plate 7 corresponding to each front adjusting groove 8, a rear adjusting groove which is upwardly open and penetrates through in the front-rear direction is provided. The front part of each aligning clamp 5 is inserted into the front adjusting groove 8, and the rear part of each aligning clamp 5 is inserted into the corresponding rear adjusting groove. A limiting plate 9 whose front side contacts with the rear side of the rear fixing plate 7 is fixed to the rear side of each aligning clamp 5. A plurality of through holes 10 which penetrate through in the left-right direction are provided at intervals before and after on the right side of each aligning clamp 5. An inlet 11 whose lower part communicates with the rear part of the through hole 10 is provided on the upper side of the aligning clamp 5 corresponding to the through hole 10. An installation hole which penetrates through in the front-rear direction is provided at the rear center of the rear fixing plate 7. The aligning oil cylinder 2 is installed on the upper side of the rear part of the workbench 1 corresponding to the installation hole. The front end of the piston rod of the aligning oil cylinder 2 passes through the installation hole and is fixedly installed with the aligning block 3. An arc-shaped aligning groove 12 which penetrates through in the left-right direction and opens forward is provided on the front side of the aligning block 3. A lifting frame 4 is provided at the rear side of the workbench 1, and a lifting mechanism capable of moving back and forth is provided at the upper part of the lifting frame 4.

[0019] During the use process, through such a setting, the lifting mechanism hoists the deformed drill rod in front of the workbench 1 to the upper side of the workbench 1, and then puts the deformed drill rod into the through hole 10, so that the bent part of the drill rod faces the aligning groove 12. When the aligning oil cylinder 2 works, the piston rod of the aligning oil cylinder 2 extends, driving the aligning block 3 to move forward. Finally, the inner wall of the aligning groove 12 squeezes the bent part of the drill rod, reducing the bent deformation part of the drill rod. Continuously squeezing multiple deformed parts of the drill rod completes the alignment work of the drill rod. The lifting mechanism makes the handling of the drill rod light, fast, improves the safety factor, reduces the labor intensity of employees, reduces the frequency of manual handling when aligning the drill rod, and shortens the alignment time of the drill rod.

[0020] According to actual needs, the above electric control grab drill rod aligning machine can be further optimized and / or improved:

[0021] Embodiment 2: As an optimization of the above embodiment, as shown in the appendix Figure 1 、 2 As shown, at least one front adjusting groove 8 is provided at intervals on the rear side of the front fixing plate 6 corresponding to the left and right positions of the through hole 10. There are two aligning clamps 5. The front part of one aligning clamp 5 is installed in the front adjusting groove 8 on the left side of the through hole 10, and the front part of the other aligning clamp 5 is installed in the front adjusting groove 8 on the right side of the through hole 10.

[0022] During the use process, through such a setting, the distance between the two aligning clamps 5 can be adjusted according to the deformation amount of the drill rod, and drill rods with various deformation amounts can be aligned, making the alignment operation of the drill rod more flexible.

[0023] Example 3: As an optimization of the above example, as shown in the attached Figure 2 figure, the width of the upper inlet 11 of each calibration card 5 gradually increases from back to front.

[0024] During use, with such a setting, the width of the inlet 11 gradually increases from back to front, so that the steel drill rod with relatively serious bending deformation can be placed into the front calibration hole 10, making the bent part of the steel drill rod face the calibration groove 12. When the calibration oil cylinder 2 works, the piston rod of the calibration oil cylinder 2 extends, driving the calibration block 3 to move forward. Finally, the inner wall of the calibration groove 12 squeezes the bent part of the steel drill rod, reducing the bent deformation part of the steel drill rod, and continuously squeezing multiple deformed parts of the steel drill rod to complete the calibration work of the steel drill rod. This can avoid the situation that the steel drill rod with relatively serious bending deformation cannot be placed into the calibration hole 10 for calibration operation. The width of the upper inlet 11 of each calibration card 5 gradually increases from back to front, that is, the width of the upper inlet 11 of each calibration card 5 gradually increases from back to front in the front-back direction.

[0025] Example 4: As an optimization of the above example, as shown in the attached Figure 1 figure, an H-shaped steel beam 13 with its front part located above the workbench 1 is rotatably installed on the upper part of the lifting frame 4. The lifting mechanism includes a suspension frame 14, a winch 15, a connecting plate 16, a cross beam 17 and a clamping jaw 18. Two roller groups are arranged at intervals in the front-back direction on the upper part of the suspension frame 14. Each roller group includes two supporting wheels 19 respectively rotatably installed on the left and right parts of the suspension frame 14. The two supporting wheels 19 are respectively rollingly installed on the upper sides of the left and right parts of the lower flange of the steel beam 13. The lower part of the suspension frame 14 and the upper part of the winch 15 are installed together. The hook of the winch 15 is installed together with the upper part of the connecting plate 16. A cross beam 17 is fixedly installed on the lower side of the connecting plate 16. Lifting lugs 20 are fixedly installed on the lower sides of the left end and the right end of the cross beam 17 respectively. A clamping jaw 18 is installed on each lifting lug 20.

[0026] According to requirements, the clamping jaw 18 is a known prior art, such as a cylindrical lifting clamp or a clamp. The winch 15 is a known prior art, such as an electric hoist of model CD. During use, with such a setting, pulling the clamping jaw 18 makes the winch 15 move back and forth on the steel beam 13, and the deformed steel drill rod in front of the workbench 1 can be hoisted to the workbench 1 for hydraulic calibration. This makes the handling of the steel drill rod light, fast, improves the safety factor, reduces the labor intensity of employees, reduces the frequency of manual handling when calibrating the steel drill rod, and shortens the calibration time of the steel drill rod.

[0027] Example 5: As an optimization of the above example, as shown in the attached Figure 1 figure, a connecting chain 21 is installed between the upper part of the clamping jaw 18 and the lifting lug 20.

[0028] According to requirements, the connecting chain 21 is a well-known steel chain in the prior art. During use, by setting the connecting chain 21, the rotation of the jaw 18 relative to the lifting lug 20 can be made more flexible, enabling the steel drill rod with relatively severe bending deformation to be smoothly hoisted to the correction station, and making the hoisting operation of the steel drill rod more flexible.

[0029] The above technical features constitute an embodiment of the present utility model, which has strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
