[0043] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0044] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0045] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0047] In one embodiment, a support hook welding tool is described, which is provided with a clamping assembly 5 and a handle assembly 4. On the one hand, the hook is clamped by the clamping assembly 5 to replace the manual clamping of the hook by the staff. On the other hand, the distance between the hook and the exhaust pipe is adjusted by applying a preset force to the handle assembly 4, and the hook is kept attached to the exhaust pipe to complete the welding of the hook and the exhaust pipe. The staff does not need to hold the hook for a long time, the operation is convenient, and the labor intensity of the staff is greatly reduced.

[0048] Specifically, see the attached drawings of the specification Figures 1 to 3 A hook support welding tool comprises a mounting frame 1, a sliding seat 2, a driving member 3, a handle assembly 4 and a clamping assembly 5, wherein the sliding seat 2 is movably arranged on the upper end surface of the mounting frame 1, and the clamping assembly 5 is arranged on the sliding seat 2 and located on one side of the mounting frame 1, and the distance between the clamping assembly 5 and the exhaust pipe is adjusted by moving the sliding seat 2. Accordingly, the driving member 3 is in transmission connection with the clamping assembly 5 to control the clamping assembly 5 to clamp the hook.

[0049] In addition, the handle assembly 4 is arranged on one side of the mounting frame 1, and one end of the handle assembly 4 is connected to the sliding seat 2. Accordingly, the handle assembly 4 has a locking mode and an unlocking mode. When the handle assembly 4 is in the unlocking mode, the sliding seat 2 can move relative to the mounting frame 1. The staff can use a preset force to pull the handle assembly 4 to drive the sliding seat 2 to move telescopically along the extension direction of the mounting frame 1, thereby adjusting the distance between the clamping assembly 5 and the exhaust pipe, thereby adjusting the distance between the hook and the exhaust pipe. When the handle assembly is in the locking mode, the sliding seat 2 is fixed on the mounting frame 1 and cannot move relative to the sliding seat 2.

[0050] The hook support welding tool provided in this embodiment is used. When the handle assembly 4 is adjusted to the unlocking mode, the staff first uses a preset force to pull the handle assembly 4 to drive the sliding seat 2 to move on the mounting frame 1, so that the sliding seat 2 and the clamping assembly 5 are away from the exhaust pipe, and then the hook is set on the clamping assembly 5, and the clamping assembly 5 is driven by the driving member 3 to clamp the hook. Then, the handle assembly 4 is pulled with a preset force to drive the sliding seat 2 to move on the mounting frame 1, so that the sliding seat 2 and the clamping assembly 5 are close to the exhaust pipe, thereby reducing the distance between the hook and the exhaust pipe, so that the hook is attached to the exhaust pipe. In the process of welding the hook to the exhaust pipe, the staff can apply a preset force to the handle assembly 4 for a long time to keep the hook attached to the exhaust pipe, so as to achieve welding between the hook and the exhaust pipe.

[0051] In addition, after the hook and the exhaust pipe are welded, there is no need to use the hook welding tool, and the handle assembly 4 can be adjusted to the locking mode to prevent the sliding seat 2 from sliding, thereby extending the service life.

[0052] In the prior art, when the hook is welded on the exhaust pipe, the worker needs to hold the hook and attach the hook to the exhaust pipe. In addition, during the process of welding the hook to the exhaust pipe, the worker needs to hold the exhaust pipe for a long time to ensure that the hook is attached to the exhaust pipe. In this process, the worker needs to hold the hook for a long time, which is labor-intensive, and it is difficult to ensure that the hook is accurately attached to the exhaust pipe, resulting in poor welding effect. In this embodiment, the hook can be clamped by the clamping assembly 5, so that the hook will not shake easily during the welding process, thereby ensuring the stability of the welding between the hook and the exhaust pipe. Moreover, the worker only needs to use a preset force on the handle assembly 4 to attach the hook to the exhaust pipe for a long time, which is easy to operate, reduces the labor intensity of the worker, and ensures the welding effect.

[0053] In one embodiment, referring to the accompanying drawings, Figure 1This embodiment further describes the hook welding tool. It also includes a push assembly 6, which is arranged on the mounting frame 1 and is suitable for applying force to the sliding seat 2. When the handle assembly 4 is in the unlocking mode, the push assembly 6 applies force to the sliding seat 2 to enable the hook on the clamping assembly 5 to abut against the exhaust pipe.

[0054] Furthermore, the push assembly 6 includes a first cylinder 61 and a connecting arm 62, wherein the first cylinder 61 is fixed on the mounting frame 1, the connecting arm 62 is vertically fixed to the output end of the first cylinder 61, and one end of the connecting arm 62 away from the first cylinder 61 is connected to the sliding seat 2. In this way, the first cylinder 61 applies force to the connecting arm 62, thereby applying force to the sliding seat 2 to attach the hook to the exhaust pipe.

[0055] It should be noted that, on the one hand, the hook can be directly attached to the exhaust pipe by applying a preset force to the handle assembly 4, and the staff can then apply a preset force to the handle assembly 4 to keep the hook on the exhaust pipe. On the other hand, after applying a preset force to the handle assembly 4 to attach the hook to the exhaust pipe, the staff can no longer apply a preset force to the handle assembly 4, and apply a force through the first cylinder 61 of the push assembly 6 to abut the hook against the exhaust pipe.

[0056] In this embodiment, after the worker uses a preset force to attach the hook to the exhaust pipe, the first cylinder 61 is ventilated so that the first cylinder 61 applies force to the sliding seat 2, thereby attaching the hook to the exhaust pipe for a long time to complete the welding of the hook and the exhaust pipe. The push assembly 6 replaces the worker's manual pulling of the handle assembly 4 to attach the hook to the exhaust pipe for a long time, further reducing the worker's labor intensity and ensuring the welding accuracy of the exhaust pipe and the hook.

[0057] In one embodiment, the present embodiment provides a specific structure of a clamping assembly 5, wherein the clamping assembly 5 comprises an upper clamp 51, a lower clamp 52, a clamping arm 53 and a support arm 54, wherein one end of the support arm 54 is arranged on the sliding seat 2, and the clamping arm 53 is hinged at one end of the support arm 54, so that the clamping arm 53 can rotate relative to the support arm 54. Accordingly, the upper clamp 51 is arranged at one end of the clamping arm 53, and the lower clamp 52 is arranged on the sliding seat 2 and is arranged opposite to the upper clamp 51. A mounting groove is arranged on the side where the upper clamp 51 and the lower clamp 52 are close to each other, so as to form an accommodation space matching one end of the hook between the upper clamp 51 and the lower clamp 52, so as to fix one end of the hook between the upper clamp 51 and the lower clamp 52. One end of the support arm 54 away from the sliding seat 2 is hinged to the middle part of the clamping arm 53.

[0058] The driving member 3 is transmission connected to the second end so that the support arm 54 is located between the first end and the second end, so as to drive the clamping arm 53 to rotate relative to the support arm 54, thereby adjusting the distance between the upper clamp 51 and the lower clamp 52, thereby fixing the hook between the upper clamp 51 and the lower clamp 52.

[0059] It can be understood that when in use, the output end of the driving member moves downward, driving the clamping arm 53 to rotate, thereby causing the upper clamp 51 to move in a direction away from the lower clamp 52 to open the upper clamp 51 and the lower clamp 52, and then the output end of the driving member moves upward, driving the clamping arm 53 to rotate, thereby causing the upper clamp 51 to move in a direction close to the lower clamp 52, and the upper clamp 51 is pressed against the lower clamp 52 for a long time, thereby realizing the clamping hook of the clamping assembly 5.

[0060] In one embodiment, referring to the accompanying drawings, Figure 1 , Figure 2 This embodiment further describes a hook welding tool. The hook welding tool further includes a magnetic member 73 and a support frame, the support frame is arranged on the sliding seat 2, and the magnetic member 73 is arranged at one end of the support frame away from the sliding seat 2. Accordingly, the magnetic member 73 is located above the clamping arm 53 and is suitable for being adsorbed and matched with the clamping arm 53.

[0061] When in use, after the handle assembly 4 drives the clamping assembly 5 to move in a direction away from the exhaust pipe, the driving member 3 drives the clamping arm 53 to rotate, so that the upper clamp 51 rotates in a direction away from the sliding seat 2, so that the clamping arm 53 is adsorbed with the magnetic member 73, and then the clamping arm 53 is adsorbed and fixed on the magnetic member 73, so that the upper clamp 51 and the lower clamp 52 are kept in an open state, which is convenient for setting the hook on the lower clamp 52 and easy to operate.

[0062] Specifically, the support frame includes a first arm 71 and a second arm 72, wherein the first arm 71 is vertically arranged on the sliding seat 2 and is located on one side of the end of the clamping arm 53 where the upper half clamp 51 is not arranged, and the second arm 72 is arranged at the end of the first arm 71 away from the sliding seat 2 and is inclined toward the direction close to the clamping arm 53. Accordingly, the magnetic attraction member 73 is arranged on the second arm 72, and the magnetic attraction member 73 is suitable for being adsorbed and fixed to the clamping arm 53.

[0063] Of course, in actual production applications, the clamping arm 53 can be made of iron, cobalt, and nickel materials to ensure that the magnetic member 73 is adsorbed and fixed to the clamping arm 53. The magnetic member 73 can be set as a magnet or an electromagnet, and the magnetic member 73 and the clamping arm 53 can be controlled to be adsorbed or separated by energizing and deenergizing the electromagnet.

[0064] In one embodiment, the present embodiment further describes the handle assembly 4. The handle assembly 4 includes a first rod 41, a first mounting member 42, a second rod 43, a connecting rod 44 and a second mounting member 45, and the first mounting member 42, the second rod 43, the connecting rod 44 and the second mounting member 45 are hingedly arranged in sequence. The second mounting member 45 is arranged on the sliding seat 2 and is located on the side of the mounting frame 1 away from the clamping assembly 5. The first mounting member 42 is arranged on the mounting frame 1 and is arranged relative to the second mounting member 45.

[0065] Correspondingly, the first rod 41 is arranged at one end of the second rod 43 close to the connecting rod 44, and one end of the second rod 43 away from the first rod 41 is arranged to tilt upwards, so that the staff can hold the first rod 41 to drive the sliding seat 2 to move.

[0066] It can be understood that, referring to the accompanying drawings of the specification Figure 1 When the handle assembly 4 is in the unlocking mode, the staff uses a preset force to drive the first rod 41 to rotate counterclockwise, driving the second rod 43 and the connecting rod 44 to rotate upward at one end close to each other, thereby shortening the length of the second rod 43 and the connecting rod 44, thereby driving the clamping assembly 5 to move away from the exhaust pipe. Similarly, the staff uses a preset force to drive the second rod 43 to rotate clockwise, thereby driving the sliding seat 2 to move toward the exhaust pipe. Before the second rod 43 and the connecting rod 44 are in a straight line, the hook has been attached to the exhaust pipe.

[0067] When the second rod 43 and the connecting rod 44 are in a straight line, the handle assembly 4 is in a locking mode. It should be noted that when the hook abuts against the exhaust pipe, the second rod 43 and the connecting rod 44 are not in a straight line, and the push assembly 6 can apply force to the sliding seat 2 to ensure that the hook abuts against the exhaust pipe. When the hook welding tool is not needed, the staff can push the first rod 41 so that the second rod 43 and the connecting rod 44 are in a straight line, and the handle assembly 4 is in a locking mode to prevent the sliding seat 2 from moving when the welding tool is not in use, thereby extending the service life.

[0068] Correspondingly, a limiting protrusion is provided on the side of one end of the second rod 43 close to the connecting rod 44, and a limiting groove matched with the limiting protrusion is provided on one end of the connecting rod 44 close to the second rod 43. After the exhaust pipe is welded, the exhaust pipe is removed, and the first rod 41 is rotated clockwise to drive the second rod 43 and the limiting protrusion to rotate until the limiting protrusion is engaged with the limiting groove. At this time, the second rod 43 and the connecting rod 44 are in a straight line, so that the handle assembly is in a locked mode.

[0069] Of course, there are many ways to put the handle assembly 4 in the locking mode. For example, the connecting rod 44 has a first part and a second part that are arranged opposite to each other, the first part is hinged to the second mounting member 45, and the second part has two clamping arms, which are arranged in parallel at one end of the first part away from the second mounting member 45, and one end of the second rod 43 is hinged between the two clamping arms. A limiting groove that matches the first rod 41 is provided at one end of the first part away from the second mounting member 45, and the limiting groove is located between the two clamping arms. When the second rod 43 and the connecting rod 44 are in a straight line, the first rod 41 is engaged with the limiting groove, thereby putting the handle assembly in the locking mode. They are not described one by one here, and they are all within the protection scope of the present utility model.

[0070] In one embodiment, referring to the accompanying drawings, Figure 1 , this embodiment further describes the sliding seat 2. The sliding seat 2 includes a connecting plate 21 and a base plate 22, and the base plate 22 is movably arranged on the mounting frame 1. The connecting plate 21 has a connecting end 211 and a receiving end 212 that are arranged opposite to each other. Accordingly, the connecting end 211 is detachably arranged on the base plate 22, and the receiving end 212 extends from the base plate 22 and is located on the side of the sliding seat 2 away from the handle assembly 4. The lower half clamp 52 is arranged on the upper end surface of the receiving end 212, and the driving member is arranged on the lower end surface of the receiving end 212.

[0071] Correspondingly, one end of the connecting arm 62 of the push assembly 6 away from the first cylinder 61 is connected to the base plate 22 , the second mounting member 45 is arranged on a side of the base plate 22 away from the driving member 3 , and the first section arm 71 is arranged on the receiving end 212 .

[0072] Preferably, an L-shaped mounting block is also provided on the base plate 22, and the mounting block has two mounting surfaces perpendicular to each other, and the two mounting surfaces are respectively arranged opposite to the two surfaces of the connecting plate 21. A gasket is provided between the two mounting surfaces and the connecting plate 21, and the gasket, the mounting block and the connecting plate 21 are fixed by bolts. In this way, the position adjustment of the connecting plate 21 is achieved by replacing gaskets of different thicknesses, that is, the position adjustment of the hook on the clamping assembly 5 is achieved. In addition, the lower half clamp 52 and the receiving end 212, and the clamping arm 53 and the upper half clamp 51 can be connected by detachable gaskets.

[0073] In one embodiment, referring to the accompanying drawings, Figure 1 In this embodiment, a lifting assembly 8 is further provided on the mounting frame 1, and the lifting assembly 8 is provided below the second rod 43. Accordingly, when the handle assembly 4 is in the locking mode, the lifting assembly 8 is adapted to push the second rod 43 to rotate, thereby releasing the second rod 43 and the connecting rod from being limited, that is, the handle assembly 4 is in the unlocking mode.

[0074] Specifically, the lifting assembly 8 is configured as a second cylinder. When air is passed into the second cylinder, the output end of the second cylinder is pushed upward to thereby push the second rod 43 to rotate, thereby releasing the limiting of the second rod 43 and the connecting rod 44 .

[0075] It is understandable that after the exhaust pipe is welded, the exhaust pipe and the hook are removed, and the handle assembly 4 is rotated so that the handle assembly 4 is in a locked mode, so that the sliding seat 2 cannot move. Correspondingly, when the hook welding tool is needed, the lifting assembly 8 is used to push the second rod 43 to rotate, so that the handle assembly 4 is in an unlocked mode.

[0076] In one embodiment, a support hook welding tool further includes a locking assembly 9, which is arranged on the clamping assembly 5. The mounting groove is arranged along a length direction perpendicular to the clamping arm 53, and the locking assembly 9 is suitable for cooperating with the end of the hook to fix the hook in the clamping assembly 5.

[0077] Specifically, see the attached drawings of the specification Figure 4 The locking assembly 9 includes an elastic member 91, a rotating rod 92, a connecting member 93 and an abutting member 94. The lower half clamp 52 includes a clamp body and an extension portion 521 arranged at one end of the clamp body. The rotating rod 92 is rotatably arranged on the outer side wall of the extension portion 521 through a fixed axis. One end of the rotating rod 92 is arranged relative to the end of the hook. The rotating rod 92 rotates to adjust the distance between the end of the hook and the rotating rod 92. The connecting member 93 is hinged at one end of the rotating rod 92 away from the hook, and the abutting member 94 is arranged at one end of the rotating rod 92 close to the hook. The outer side wall of the extension portion 521 is provided with a mounting hole, one end of the elastic member 91 is arranged in the mounting hole, the other end of the elastic member 91 is connected to one end of the rotating rod 92, and the elastic member 91 is in a compressed state.

[0078] It is understandable that, under the action of the driving member 3, one end of the hook is clamped between the upper clamp 51 and the lower clamp 52, and one end of the hook is matched with the mounting groove. Under the action of the restoring force of the elastic member 91, the abutting member 94 rotates toward the direction close to the clamping assembly 5, and then contacts and presses with the end of the hook, so that one end of the hook in the length direction is contacted and pressed, further improving the connection strength of the hook set on the clamping assembly 5.

[0079] Preferably, the locking assembly 9 further comprises a driving handle 95 , which is disposed on a side of the rotating rod 92 away from the clamping assembly 5 , so that a worker can use the driving handle 95 to release the limiting fit between the locking assembly 9 and the hook.

[0080] Furthermore, a slide rail assembly is also included, which is arranged between the base plate 22 and the mounting frame 1, so that the base plate 22 moves relative to the mounting frame 1.
