Description

Technical Field

[0001] This utility model relates to the field of corrugated machine production technology, and in particular to a disassembly device for a steam pipe fixing handwheel of a corrugated machine. Background Technology

[0002] In corrugated cardboard production equipment, replacing the corrugated roll assembly is a core maintenance step, requiring simultaneous disassembly of the connected steam pipe components. In existing technology, steam pipe joints are mostly secured with flanges and bolts, and connected with handwheels. However, when replacing the corrugated roll assembly, the operating space is limited, and the handwheels, due to their small size, lack sufficient torque, making it difficult for operators to apply effective tightening force, easily leading to leaks due to poor sealing. Furthermore, the steam pipes operate at temperatures as high as 150-200℃, and traditional metal handwheels lack heat insulation; direct contact with high-temperature components during disassembly can easily cause burns, making disassembly difficult.

[0003] Therefore, in order to address the shortcomings of the existing technology, a disassembly device for fixing the handwheel of the steam pipe of a corrugating machine is provided. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a disassembly device for the fixing handwheel of the steam pipe of a corrugating machine, which aims to solve the problems of difficult assembly and disassembly and excessive temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A disassembly device for fixing the handwheel of a corrugated machine steam pipe includes:

[0007] A connecting seat, wherein the connecting seat is provided with a notch, several grooves and several screw clips, the notch penetrates through the steam pipe, and the several screw clips engage with the screws on the fixed handwheel;

[0008] A wrench assembly includes a wrench body, an upper crossbar, and a lower crossbar. Both the upper and lower crossbars are fixedly connected to the wrench body. When the wrench is turned, the lower crossbar extends into the groove and abuts against the inner wall of the groove, while the upper crossbar abuts against the outer wall of the connecting seat.

[0009] As a further improvement to the technical solution of this utility model, the connecting seat is arc-shaped.

[0010] As a further improvement to the technical solution of this utility model, the groove is located on the outer peripheral wall of the connecting seat, and the screw buckle is located on the inner peripheral wall of the connecting seat.

[0011] As a further improvement to the technical solution of this utility model, the cross-section of the connecting seat is C-shaped.

[0012] As a further improvement to the technical solution of this utility model, the length of the upper crossbar is greater than the length of the lower crossbar.

[0013] As a further improvement to the technical solution of this utility model, the groove is provided with an opening, and the width of the opening is greater than the thickness of the wrench assembly.

[0014] As a further improvement to the technical solution of this utility model, the cross-section of the groove is convex.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this utility model, the disassembly device for the fixing handwheel of the corrugated machine steam pipe is used by inserting the notch on the connecting seat through the steam pipe, engaging the screw clip into the screw on the fixing handwheel, holding the main body of the lever, inserting the lower crossbar into the groove and rotating it 90°, and then turning the main body of the lever downwards or upwards so that the upper and lower crossbars are engaged in the groove. Turning the main body of the lever downwards or upwards drives the connecting seat to rotate, thus completing the assembly and disassembly of the fixing handwheel. The steam pipe is separated from the operator by the connecting seat and the main body of the lever, preventing burns. This utility model's disassembly device for the fixing handwheel of the corrugated machine steam pipe is suitable for narrow spaces, simple to disassemble, and avoids burns.

[0023] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0024] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or it can be indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," and "right" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

[0025] Reference Figures 1 to 2 A disassembly device for fixing the handwheel of a corrugated machine steam pipe includes a connecting seat 1 and a wrench assembly 2, wherein the connecting seat 1 and the wrench assembly 2 are detachably connected.

[0026] In one embodiment, the connecting seat 1 has a notch 11, several grooves 12, and three screw clips 13. The notch 11 penetrates the steam pipe, and the three screw clips 13 engage with the three screws on the fixed handwheel, ensuring a tight connection between the connecting seat 1 and the fixed handwheel on the steam pipe without relative displacement. The wrench assembly 2 includes a wrench body 21, an upper crossbar 22, and a lower crossbar 23. Both the upper crossbar 22 and the lower crossbar 23 are fixedly connected to the wrench body 21. When actuated, the lower crossbar 23 extends into the groove 12 and abuts against the inner wall of the groove 12, while the upper crossbar 22 abuts against the outer wall of the connecting seat 1. Preferably, the lower crossbar 23 can move within the groove 12, adjusting the actuation angle of the wrench body 21. This allows for a larger actuation angle, suitable for narrow operating spaces.

[0027] In use, the notch 11 on the connecting seat 1 is inserted through the steam pipe, and the screw clip 13 is engaged with the screw on the fixing handwheel. Holding the lever body 21, the lower crossbar 23 is inserted into the groove 12 and rotated 90°. The lever body 21 is then pulled down or up, causing the upper crossbar 22 and lower crossbar 23 to engage in the groove 12. Pulling the lever body 21 down or up causes the connecting seat 1 to rotate, thus completing the installation and removal of the fixing handwheel. The steam pipe is separated from the operator by the connecting seat 1 and the lever body 21, preventing burns. This invention's disassembly device for fixing the handwheel of a corrugated machine steam pipe is suitable for use in confined spaces, easy to disassemble, and avoids burns.

[0028] In one embodiment, the connector 1 is arc-shaped. The cross-section of the connector 1 is C-shaped. Preferably, the width of the notch 11 is greater than the diameter of the steam pipe.

[0029] In one embodiment, the groove 12 is located on the outer peripheral wall of the connecting seat 1, and the screw buckle 13 is located on the inner peripheral wall of the connecting seat 1. Preferably, the groove 12 is also provided with a limiting part, which is located at the front and rear ends of the groove 12. When the fixed handwheel is difficult to disassemble, and the friction between the wrench assembly 2 and the groove 12 is insufficient to turn the fixed handwheel, the wrench assembly 2 is moved to the limiting part, and the contact between the wrench body 21 and the limiting part serves as the force point to turn the fixed handwheel.

[0030] In one embodiment, the groove 12 has an opening, the width of which is greater than the thickness of the wrench assembly 2, to facilitate the lower crossbar 23 extending into the groove 12. The groove 12 has a convex cross-section. Preferably, the groove 12 also has a first abutting surface, and the outer peripheral wall of the connecting seat 1 has a second abutting surface. The lower crossbar 23 is abutted against the first abutting surface, and the upper crossbar 22 is abutted against the second abutting surface. The connecting seat 1 is rotated by the friction between the first and second abutting surfaces.

[0031] In one embodiment, the length of the upper crossbar 22 is greater than the length of the lower crossbar 23.

[0032] Preferably, since a large amount of force is required to turn the lever body 21, a wrench cover can also be provided on the outer surface of the lever body 21.

[0033] In one embodiment, the lever body 21 is used as a long lever, and the upper crossbar 22 and lower crossbar 23 are used as fulcrums. Disassembly is achieved through the lever principle, which makes the process more labor-saving.

[0034] Other aspects of the disassembly device for the fixing handwheel of the corrugated machine steam pipe described in this utility model are referred to in the prior art and will not be repeated here.
