Description

Technical Field

[0001] The utility model relates to the field of clamping devices, in particular to an insulating arm bonding and positioning tool. Background Art

[0002] In the prior art, when repairing lines, especially high-voltage lines, due to their high height from the ground, an insulated boom truck is generally used for construction operations. The insulated boom truck has an insulated arm, such as Figure 1 As shown, the insulating arm is divided into sections, including a first supporting section 81 and a second supporting section 83 made of metal, and an insulating section 82 is arranged between the first supporting section 81 and the second supporting section 83, respectively, and the first supporting section 81 and the second supporting section 83 are insulated from each other by the arrangement of the insulating section 82. A first pin shaft hole 84 for the pin shaft to pass through is also arranged at one end of the first supporting section 81 away from the insulating section 82, and a second pin shaft hole 85 for the pin shaft to pass through is also arranged at one end of the second supporting section 83 away from the insulating section 82, and the first pin shaft hole 84 and the second pin shaft hole 85 facilitate the matching connection with the surrounding parts.

[0003] The connection between the insulating section and the first support section and the second support section is often matched by bolt fixing, but the stress concentration at the bolt connection is relatively large. With the advancement of material technology, there is also a solution in the prior art to bond the insulating section to the first support section and the second support section. Specifically, the insulating section and the first support section and the insulating section and the second support section are arranged in a form that can be plugged into each other, and a first plug-in portion inserted into the insulating section is arranged on the first support section, and a second plug-in portion inserted into the insulating section is arranged on the second support section. The cross-sections of the first plug-in portion and the second plug-in portion are both rectangular. A first plug-in hole that plugs with the first plug-in portion and a second plug-in hole that plugs with the second plug-in portion are respectively arranged at both ends of the insulating section. After the first plug-in portion and the first plug-in hole are matched, and the second plug-in portion and the second plug-in hole are matched, glue is applied to the plug-in matching position for fixing.

[0004] During the process of applying glue, each inner wall surface of the first socket maintains a gap with the first plug-in part, so that each inner wall surface of the first socket and the outer peripheral surface of the first plug-in part can be coated with enough glue, thereby ensuring that each side of the plug-in mating part has sufficient adhesion. The same is true for the second socket and the second plug-in part. Therefore, the size of the first socket is larger than the size of the first plug-in part, and the size of the second socket is larger than the size of the second plug-in part. Naturally, during the mating process, shaking may occur between the first support section, the insulating section and the second support section, resulting in adhesive deformation. In addition, after completing the assembly of each section separately, it is possible that the overall size exceeds the standard value, making the overall size too large or too small. Utility Model Content

[0005] The purpose of the utility model is to provide an insulating arm bonding and positioning tool, which is used to solve the problem in the prior art that during the bonding process of the insulating section and the first supporting section and the second supporting section, there is no effective limit, resulting in the overall size being too large or too small after the bonding is completed, causing the insulating arm to fail to meet the standards.

DETAILED DESCRIPTION

[0025] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0026] In the utility model, a first positioning structure for supporting and fixing the first supporting segment, an insulating segment positioning structure for supporting and fixing the insulating segment, and a second positioning structure for supporting and fixing the second supporting segment are fixedly arranged on the same base to avoid deformation during the bonding process.

[0027] In the embodiment 1 of the insulating arm bonding and positioning tool in the utility model:

[0028] like Figure 2As shown, in this embodiment, the insulating arm bonding and positioning tooling includes a base 1, on which a first positioning structure for supporting and fixing the first support segment 81, an insulating segment positioning structure for supporting and fixing the insulating segment 82, and a second positioning structure for supporting and fixing the second support segment 83 are fixedly arranged. A walking wheel 11 is arranged at the bottom of the base 1 to facilitate the transfer of the insulating arm bonding and positioning tooling and the insulating arm. The first support segment 81, the insulating segment 82, and the second support segment 83 are fixed and supported by these three positioning structures respectively. During the bonding process, it takes a certain amount of time from the beginning of glue application to the curing of the glue. The first support segment 81, the insulating arm, and the second support segment 83 are fixed by these three positioning structures to avoid relative movement before the glue is cured, thereby causing deformation of the insulating arm. At the same time, the above-mentioned first positioning structure, the insulating segment positioning structure, and the second positioning structure are all fixed on the base 1, which is also convenient for forming a unified benchmark, which is convenient for positioning the various parts of the insulating arm. Of course, in other embodiments, the walking wheel 11 can no longer be arranged at the bottom of the base 1.

[0029] After the insulating arm is assembled and manufactured, the first pin hole 84 of the first support section 81 and the second pin hole 85 of the second support section 83 need to cooperate with the surrounding parts during use. Therefore, during the manufacturing and assembly process, a structure for positioning the first pin hole 84 and the second pin hole 85 is also provided. Specifically, the first positioning structure includes a first bracket 2 for being arranged at the end of the insulating arm, and the second positioning structure includes a second bracket 7 for being arranged at the pin hole of the second support section 83. The first bracket 2 is provided with a first positioning hole 21, and the second bracket 7 is provided with a second positioning hole 76. The first bracket 2 and the second bracket 7 are both fixedly provided on the base 1, so as to ensure that the sizes of the first positioning hole 21 and the second positioning hole 76 meet the actual requirements. That is to say, the size requirements of the two installation points of the insulating arm are met by the first bracket 2 and the second bracket 7, and then the coaxiality of the insulating arm needs to be met.

[0030] like Figure 2 and Figure 5As shown, the first bracket 2 includes a first support plate 22 and a second support plate 23 arranged vertically and at intervals, and the first support plate 22 and the second support plate 23 are provided with first positioning holes 21 arranged oppositely, and the first positioning hole 21 is provided with a first pin 24 for cooperating with the first pin hole 84 on the insulating arm. The second bracket 7 includes a third support plate 71 and a fourth support plate 72 arranged vertically and at intervals, and the third support plate 71 and the fourth support plate 72 are provided with second positioning holes 76 arranged oppositely, and the second positioning hole 76 is provided with a second pin 77 for cooperating with the second pin hole 85 on the insulating arm. Of course, in other embodiments, the first bracket and the second bracket can also be integrally formed into a block structure. Alternatively, in other embodiments, the first bracket and the second bracket can no longer be provided with the first pin and the second pin, but can be configured by the user, or the first pin is a two-stage structure, which is plugged in from both sides; the second pin is also a two-stage structure, which is also plugged in from both sides when in use.

[0031] like Figure 2 and Figure 3 As shown, the first positioning structure also includes an auxiliary support frame 3 arranged at intervals with the first bracket 2. Since the length of the first support section 81 is long and the weight is large, two auxiliary support frames 3 are provided. The two auxiliary support frames 3 are arranged at intervals with the first bracket 2, and the first bracket 2 is located at the end of the base 1. The structures of the two auxiliary support frames 3 are the same, and the structure of the auxiliary support frame 3 is described by taking one of them as an example. The auxiliary support frame 3 includes a first mounting plate 31 and a second mounting plate 32 arranged at intervals, and a connecting plate 33 is also provided between the two mounting plates. A first support block 34 is fixed on the connecting plate 33 by bolts. In order to adjust the height of the first positioning structure, a first adjustment gasket is also provided between the first support block 34 and the connecting plate 33. The gap between the first support block 34 and the connecting plate 33 is adjusted by changing the number of the first adjustment gaskets used and the specification thickness of the first adjustment gasket, thereby changing the height of the top surface of the first support block 34, that is, adjusting the height of the first positioning structure. Of course, in other embodiments, the auxiliary support frame can also be set as a block-shaped support frame, and two mounting plates and connecting plates are no longer provided. Alternatively, in other embodiments, the auxiliary support frame may be provided in only one or three or other numbers. Alternatively, in other embodiments, the first adjustment gasket may not be provided, and multiple groups of first support blocks of different specifications and heights may be provided, and different first support blocks may be selected according to requirements.

[0032] The first support block 34 needs to support the first support section 81, so the upper surface of the first support block 34 constitutes the first support surface for supporting the first support section 81. The top of the first support block 34 is provided with a recessed portion that is recessed downward. Through the provision of the recessed portion, the first support surface is formed at both ends of the first support block 34, which reduces the support area and also makes it easier to maintain the flatness of the first support surface, so that when supporting the first support section 81, it is easier to maintain the flatness of the first support section 81. Of course, in other embodiments, the recessed portion may no longer be provided, and the entire upper surface of the first support block 34 constitutes the first support surface.

[0033] In order to complete the fixing of the first support section 81, a first abutment block 35 for abutting and contacting the side of the first support section 81 is also provided on the first mounting plate 31. The first abutment block 35 is a metal block welded on the first mounting plate 31, and two are arranged at intervals up and down to form a plane. A first tightening and fixing platform arranged away from the first mounting plate 31 is provided on the second mounting plate 32 of the auxiliary support frame 3. A first tightening structure 4 for tightening the first support section 81 against the first abutment block 35 is fixedly provided on the first tightening and fixing platform. The first tightening structure 4 is a quick clamp, and a tightening spring is provided inside it, which is convenient for tightening the first support section 81 against the first abutment block 35 to complete the clamping and fixing of the first support section 81. Of course, the first tightening structure can also be in other forms, such as a tightening cylinder. The first abutment block can also be bonded to the first mounting plate, or the first abutment block is no longer provided, and the first mounting plate is finely processed to maintain its flatness.

[0034] like Figure 2 and Figure 4 As shown, the insulating segment 82 needs to be plugged into the first supporting segment 81. During the plugging process, it is necessary to maintain the matching with the first supporting segment 81. At the same time, after the plugging is completed, the insulating segment positioning structure needs to effectively support the insulating segment 82. Therefore, the insulating segment positioning structure includes a lifting platform 5 set on the base 1. The height adjustment of the lifting platform 5 facilitates the lowering of the height of the lifting platform 5 before the plugging is performed to avoid interference between the lifting platform 5 and the insulating segment 82. After the plugging is completed, the height of the lifting platform 5 is raised to facilitate the support of the insulating segment 82. The lifting platform 5 is a manual lifting platform. Of course, in other embodiments, the lifting platform may not be set, but the insulating segment positioning structure is kept in a position where the plugging and matching of the insulating segment and the first supporting segment can be completed and the insulating segment can be supported.

[0035] The supporting structure of the insulating segment 82 also includes a door-shaped frame 63 arranged on both sides of the insulating segment 82, and the door-shaped frames 63 on both sides are respectively fixedly arranged on the base 1, and a second top tightening structure 61 and a third top tightening structure 62 for clamping the insulating segment 82 are arranged on the base 1, and the second top tightening structure 61 and the third top tightening structure 62 are arranged relatively, and the second top tightening structure 61 and the third top tightening structure 62 respectively have a top extension end, which is convenient for clamping the insulating segment 82. Of course, in other embodiments, the second top tightening structure 61 and the third top tightening structure 62 may no longer be provided, but the insulating segment 82 may be maintained in position by its own weight.

[0036] like Figure 2 and Figure 5 As shown, the second positioning structure includes a second bracket 7, a crossbeam 73 is further connected between the third support plate 71 and the fourth support plate 72, a second support block 74 is arranged on the crossbeam 73, and a second adjustment gasket for changing the gap distance between the second support block 74 and the crossbeam 73 is further arranged between the second support block 74 and the crossbeam 73, and the adjustment is performed by changing the number of second adjustment gaskets used and the specification thickness of a single second adjustment gasket. The structure of the second support block 74 is the same as that of the first support block 34, and will not be repeated here. Of course, in other embodiments, two support plates may no longer be provided, but a positioning block for fixing the second support block 74 may be provided. Alternatively, in other embodiments, the second adjustment gasket may no longer be provided, and the second support block 74 may be set to a variety of specifications.

[0037] A second abutment block 75 for abutting against the side surface of the second support section 83 is provided on the third support plate 71 or the fourth support plate 72, and an avoidance portion for avoiding the second positioning hole 76 is provided on the second abutment block 75. When fixed installation is performed, the pin shaft passing through the second positioning hole 76 is avoided.

[0038] like Figure 2 and Figure 6As shown, when bonding the insulating arm, first place the first support section 81 on the first positioning structure, keep the first pin hole 84 on the first support section 81 and the first positioning hole 21 connected and fixed by the pin, then place the other parts of the first support section 81 on the auxiliary support frame 3, and use a measuring tool such as a laser rangefinder to measure whether the various parts of the first support section 81 are at the same height as the base 1. At the same time, adjust the height of the first support block 34 so that the first support section 81 is placed in place. Then make the first tightening structure 4 tighten the first support section 81 on the first abutment block 35, then plug the insulating section 82 with the first support section 81, put a gasket in the gap between the insulating section 82 and the first support section 81 to keep the gap between the insulating section 82 and the first support section 81, so as to facilitate the injection of glue, at this time, control the lifting platform 5 to rise to support the insulating section 82, and then control the second tightening structure 61 and the third tightening structure 62 to clamp the insulating section 82. Then, the second support segment 83 is inserted into the insulating segment 82, and a pin is used to simultaneously pass through the second positioning hole 76 and the second support segment 83, and a gasket is inserted at the matching position of the second support segment 83 and the insulating segment 82 to maintain the gap for glue. Finally, glue is applied between the insulating segment 82 and the first support segment 81 and between the insulating segment 82 and the second support segment 83. Before applying glue, the entire device can be moved to a relatively closed environment using the walking wheels 11 for glue injection.
