Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling, and more specifically, to a simple tooling for pipe-to-pipe butt jointing. In addition, it also relates to a butt jointing assembly comprising the simple tooling for pipe-to-pipe butt jointing. Background Art
[0002] There are various slender tubular drill rods on the market, such as rotary drilling rods, long spiral drill rods, and mixing drill rods. Drill rods are products that require frequent maintenance for customers. There is no factory environment at the construction site, and the site conditions are poor and the environment is harsh. If cracks (horizontal or vertical cracks) are found on the steel pipe, and the failure forms such as excessive size, such as Figure 1 As shown in the figure, the steel pipe must be cut off for repair. That is, it is necessary to remove the original steel pipe surface parts (such as key strips) around the cutting ring surface. Figure 2 As shown, align the new butt steel pipe with it, as shown Figure 3 As shown, finally, weld the two aligned steel pipes and add the original key parts, as shown in Figure 4 However, the reconnection of two steel pipes has certain coaxiality requirements. In the prior art, there is no condition to quickly, accurately and conveniently align the two steel pipes on the construction site, that is, it is very difficult to adjust the two steel pipes up and down, left and right, and it is difficult to ensure the accuracy requirements.
[0003] At present, when repairing steel pipes, wood or other objects are usually placed on the ground, one end of the steel pipe is fixed on the wood or other objects, and a jack is placed under the other end of the steel pipe. Figure 5 As shown. However, the jack is inconvenient to operate and can only adjust the up and down position of the steel pipe. The left and right position adjustment of the steel pipe requires manual tapping, which can easily cause the steel pipe to fall and cause injuries to people, and ultimately make it difficult to ensure the on-site maintenance accuracy of the steel pipe (that is, the parts that need to be docked and have coaxiality requirements).
[0004] In summary, how to provide a simple riveting tool that is convenient for on-site maintenance of steel pipes is a problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION
[0046] 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.
[0047] The core of the utility model is to provide a simple pipe-to-pipe joint tool, which is a simple riveting tool that is convenient for on-site maintenance of steel pipes. Another core of the utility model is to provide a joint assembly including the simple pipe-to-pipe joint tool.
[0048] Please refer to Figures 6 to 18 .
[0049] This specific embodiment provides a simple pipe-to-pipe joint tool, including:
[0050] The first clamp 1;
[0051] The second clamp 2 is connected and matched with the first clamp 1 to form a circular ring structure, and the circular ring structure is used to be sleeved on the outer periphery of the first steel pipe 4;
[0052] The adjusting device 3 includes a mounting portion extending axially relative to the annular structure and an adjusting portion for abutting against the outer periphery of the second steel pipe 5. The adjusting portion is arranged at one end of the mounting portion, and the other ends of the plurality of mounting portions are arranged at intervals along the circumference of the annular structure.
[0053] In actual use, the shape, structure, size, material, etc. of the first clamp 1, the second clamp 2 and the adjustment device 3 can be determined according to actual conditions and actual needs.
[0054] When using the simple pipe-to-pipe docking tool provided by the utility model to dock two sections of steel pipes, first, the first clamp 1 and the second clamp 2 can be connected to form a circular ring structure. Then, the circular ring structure is sleeved on the outer periphery of the first steel pipe 4. If there is a large gap between the circular ring structure and the first steel pipe 4, a pad can be inserted into the annular groove formed by the circular ring structure and the first steel pipe 4, and a plurality of pads are symmetrically distributed along the annular groove so that the circular ring structure and the first steel pipe 4 are coaxially distributed. Finally, the second steel pipe 5 can be hoisted to a position corresponding to the end of the first steel pipe 4, and the first steel pipe 4 and the second steel pipe 5 can be docked. At this time, the positioning of the second steel pipe 5 can be achieved by the adjustment device 3, that is, the position of the second steel pipe 5 can be adjusted by using a plurality of adjustment devices 3. The adjusting parts of the multiple adjusting devices 3 are coordinated and adjusted until the ends of the multiple adjusting parts are all extended out by the same distance and are all in contact with the outer periphery of the second steel pipe 5. At this time, it indicates that the second steel pipe 5 and the annular structure are coaxially distributed, that is, the second steel pipe 5 and the first steel pipe 4 are coaxially distributed, so as to effectively ensure the coaxiality of the butt welding of the two steel pipes, which helps to improve the on-site maintenance accuracy of the steel pipe and reduce the labor intensity of the operators.
[0055] In summary, the simple pipe-to-pipe jointing tool provided by the utility model is a simple riveting tool that is convenient for on-site maintenance of steel pipes.
[0056] In one embodiment, the first clamp 1 and the second clamp 2 are detachably connected to facilitate the disassembly and assembly of the first clamp 1 and the second clamp 2. For example, the first clamp 1 and the second clamp 2 are connected at only one end, and the other end is not connected, so that the unformed circular ring structure can be sleeved on the outer periphery of the first steel pipe 4, and then, the other ends of the first clamp 1 and the second clamp 2 are connected, so that the formed circular ring structure is completely sleeved on the outer periphery of the first steel pipe 4.
[0057] In one embodiment, the top of the first hoop 1 is provided with a first lifting ear 11 and a first hinge 12, and the top of the second hoop 2 is provided with a second lifting ear 21 and a second hinge 22. The first lifting ear 11 and the second lifting ear 21 are used to pass the wire rope 6, and the first hinge 12 and the second hinge 22 are hinged. The structure is shown in FIG. Fig.11 shown.
[0058] It should be noted that when the tops of the first hoop 1 and the second hoop 2 need to be connected, the holes of the first lifting ear 11 and the second lifting ear 21 can be overlapped, and the wire rope 6 can be passed through the holes of the first lifting ear 11 and the second lifting ear 21 to lift them. Fig.12 As shown, since the first lifting lug 11 and the second lifting lug 21 are both fixed by the wire rope 6, the first clamp 1 and the second clamp 2 will open to a certain angle when lifted. The width of the lower opening of the left and right clamps is larger than the repair workpiece, and it is put down. The structure is as shown Fig.13After the wire rope 6 is loosened, it falls on one end of the workpiece to be repaired. Due to the wide gap between the first lifting lug 11 and the second lifting lug 21, the wire rope 6 is slightly loosened, the holes of the first lifting lug 11 and the second lifting lug 21 are staggered, and the first hinge 12 of the first hoop 1 and the second hinge 22 of the second hoop 2 are hinged, so that the top of the first hoop 1 and the top of the second hoop 2 are in a closed state. The structure is as shown in FIG. Fig.14 shown.
[0059] In one embodiment, the tops of the first clamp 1 and the second clamp 2 are both provided with a lifting ear and a first mounting seat, and the two first mounting seats are aligned and provided with mounting holes for mounting bolts. That is, the first clamp 1 and the second clamp 2 can be connected by bolts in addition to being connected by hinges.
[0060] When the tops of the first and second hoop 1 and 2 need to be connected, the holes of the lifting ears of the first and second hoop 1 and 2 can be overlapped, and the wire rope 6 can be passed through the holes of the two lifting ears to lift them. Since both lifting ears are fixed by the wire rope 6, the first and second hoop 1 and 2 will open to a certain angle when lifted. The first and second hoop 1 and 2 are opened below and the width is larger than the repair workpiece, and they are put down. After the wire rope 6 is relaxed, it falls on one end of the workpiece to be repaired. Since there is a wide gap between the two lifting ears, the wire rope 6 is slightly relaxed, and the holes of the two lifting ears are staggered. When the mounting holes of the two first mounting seats are aligned, bolts can be inserted to fix the first and second hoop 1 and 2 by bolts.
[0061] In one embodiment, one of the bottoms of the first hoop 1 and the second hoop 2 is provided with a reversible locking bolt 7, and the other is provided with a fixing seat 8 for fixing the locking bolt 7. When the top of the first hoop 1 and the top of the second hoop 2 are connected, the locking bolt 7 can be turned over to a position where it is assembled and connected with the fixing seat 8, so that the bottom of the first hoop 1 and the bottom of the second hoop 2 are connected by the locking bolt 7 and the fixing seat 8. Fig.15 shown.
[0062] In one embodiment, the bottom of the first clamp 1 and the second clamp 2 are both provided with a second mounting seat, and the two second mounting seats are aligned with mounting holes for mounting bolts. After the top of the first clamp 1 and the top of the second clamp 2 are connected, the mounting hole of the second mounting seat at the bottom of the first clamp 1 and the mounting hole of the second mounting seat at the bottom of the second clamp 2 are aligned, and bolts are passed through the two mounting holes to fix them.
[0063] In one embodiment, a third lifting lug 9 is provided on one side of one of the first hoop 1 and the second hoop 2. When the first steel pipe 4 and the second steel pipe 5 are coaxially aligned for assembly, if the steel pipe workpiece needs to be taken out, the steel wire rope 6 or the like can be inserted into the third lifting lug 9, and the structure for fixing the bottom of the first hoop 1 and the second hoop 2 can be opened (the locking relationship between the locking bolt 7 and the fixing seat 8 can be released, or the locking relationship between the second mounting seat and the bolt can be released). After that, the steel wire rope 6 is lifted, so that one hoop is lifted first, and the first hoop 1 and the second hoop 2 can be opened eccentrically as a whole (when the tops of the first hoop 1 and the second hoop 2 are hinged), which facilitates the removal of the steel pipe workpiece.
[0064] It should be noted that the positions of the first lifting ear 11 and the second lifting ear 21 can be set according to actual conditions, so that the first clamp 1 and the second clamp 2 are opened vertically or horizontally, and the position of the third lifting ear 9 can also be set according to actual conditions, so that the overall structure of the first clamp 1 and the second clamp 2 is tilted on one side, thereby facilitating the removal of the steel pipe workpiece.
[0065] In one embodiment, the mounting portion includes a mounting arm 31, the adjusting portion includes an adjusting bolt 32, the end of the mounting arm 31 is provided with a mounting channel, the adjusting bolt 32 passes through the mounting channel and abuts against the second steel pipe 5, and the structure is as follows: Fig.16 As shown, the first steel tube 4 and the second steel tube 5 are ensured to be coaxially distributed, and the coaxial alignment operation of the first steel tube 4 and the second steel tube 5 is simple and convenient.
[0066] In one embodiment, the first clamp 1 and the second clamp 2 are both semi-circular structures, and the semi-circular structures are provided with at least two adjustment devices 3 at equal intervals along the circumferential direction. Figure 6 and Figure 8 As shown (for example, the semicircular ring structure is provided with three adjustment devices 3 at equal intervals along the circumferential direction), this facilitates the processing and manufacturing of the device, and can also improve the structural stability of the second steel pipe 5, which helps to ensure the coaxiality of the first steel pipe 4 and the second steel pipe 5.
[0067] In order to further illustrate the method of using the simple pipe-to-pipe joint tooling provided by the utility model, the following example is taken as an example in which the top of the first clamp 1 and the top of the second clamp 2 are hinged, and the top of the first clamp 1 and the top of the second clamp 2 are connected by a locking bolt 7 and a fixing seat 8.
[0068] Step 1: Place the hinged first hoop 1 and the second hoop 2 on the ground, then open the first hoop 1 and the second hoop 2 along the hinge. When the holes of the first lifting ear 11 and the second lifting ear 21 overlap, pass the wire rope 6 through the overlapping holes to lift the device. Fig.12 As shown, since the first lifting ear 11 and the second lifting ear 21 are fixed by the wire rope 6, the first hoop 1 and the second hoop 2 will open to a certain angle when lifted;
[0069] Step 2: If Fig.13 As shown, the opening width of the first clamp 1 and the second clamp 2 below is larger than the repair workpiece, and the workpiece is put down;
[0070] Step 3: After the wire rope 6 is loosened, it falls on one end of the repair workpiece. Due to the wide gap between the first lifting eye 11 and the second lifting eye 21, when the wire rope 6 is slightly loosened, the holes of the first lifting eye 11 and the second lifting eye 21 are staggered, and the first hinge 12 of the first hoop 1 and the second hinge 22 of the second hoop 2 can be restored to the closed state. The structure is as follows: Fig.14 As shown;
[0071] Step 4: After the locking bolt 7 is swung to connect with the fixing seat 8, tighten the locking nut to fix the first clamp 1 and the second clamp 2 relatively. Fig.16 As shown, the first clamp 1 and the second clamp 2 are fixed on one end of the steel pipe, and the mounting arm 31 extends relative to the annular structure. At this time, the required second steel pipe 5 can be adjusted, and the end of the second steel pipe 5 falls into the annular area composed of a plurality of adjusting bolts 32, and the end of the adjusting bolt 32 abuts against the middle of the second steel pipe 5, so that the relative position of the first steel pipe 4 and the second steel pipe 5 can be adjusted by the adjusting bolt 32, so that the two steel pipes are coaxially distributed;
[0072] Step 5: After the welding or riveting operation of the first steel pipe 4 and the second steel pipe 5 is completed, the steel wire rope 6 is inserted into the third lifting lug 9, and the locking bolt 7 is opened. The structure is as follows: Fig.17 As shown;
[0073] Step 6: Lift the wire rope 6. Since the hoop with the third lifting lug 9 is lifted first, the hinged integral structure of the first hoop 1 and the second hoop 2 is eccentrically opened, making it convenient to lift the steel pipe workpiece. Fig.18 This device simplifies the assembly and maintenance operations of two steel pipes, and also ensures the safety of operators and the accuracy of steel pipe docking, and can be promoted for use.
