[0023] Example 1
[0024] like Figure 1-4As shown in the figure, this utility model embodiment proposes a lifting device for the ZJ118 cork paper guard door, which is installed on the frame of the ZJ118 equipment. The lifting device includes a connecting plate 1 and a support rod 2. The middle part of the connecting plate 1 is rotatably mounted on the frame. Specifically, a hinge shaft 3 is provided between the connecting plate 1 and the frame. One end of the hinge shaft 3 is fixedly connected to the frame, and the other end is rotatably connected to the middle part of the connecting plate 1 through a bearing. One end of the connecting plate 1 is threaded with a bolt 5, and the other end is integrally formed with the support rod 2. The guard door is supported on the support rod 2. In this embodiment, the structure of the guard door and the support rod 2 has been fully disclosed in the prior art, and will not be described in detail here. A linear drive assembly is rotatably connected to bolt 5. The top end of the linear drive assembly is rotatably connected to bolt 5, and the bottom end is rotatably connected to the frame. A gate block 4 is provided between bolt 5 and connecting plate 1. Gate block 4 and linear drive assembly are located on the same side of connecting plate 1. One end of gate block 4 is connected to connecting plate 1, and the other end is connected to bolt 5. The distance from the connection node of gate block 4 and bolt 5 to connecting plate 1 is greater than the distance from the connection node of linear drive assembly and bolt 5 to connecting plate 1. With this structural design, the connection method between bolt 5 and connecting plate 1 is changed from the existing single-sided connection to a double-sided force-bearing method. The force borne by the root of bolt 5 is only half of the original, the problem of force concentration on bolt 5 is improved, and its service life is greatly extended (the service life of bolt 5 has been extended from the original 1-2 months to the current two and a half years without breakage). At the same time, bolt 5 is not easy to break, avoiding the safety hazard of the protective door falling and injuring people.
[0025] Bolt 5 includes a screw and nut 53. The screw includes a threaded section 51 and a smooth section 52. One end of the smooth section 52 is fixedly connected to the nut 53, and the other end is fixedly connected to the threaded section 51. The diameter of the smooth section 52 is larger than the diameter of the threaded section 51. A threaded hole is provided on the connecting plate 1 to engage with the threaded section 51. The linear drive assembly includes a cylinder 6 and a spherical bearing rod 7. The bottom end of the cylinder 6 is rotatably connected to the frame, and the top end is fixedly connected to the bottom end of the spherical bearing rod 7. The top end of the spherical bearing rod 7 is rotatably sleeved on the smooth section 52. The rotation axis of the cylinder 6 and the frame, and the rotation axis of the spherical bearing rod 7 and the bolt 5 are all parallel to the axis of the bolt 5. In this embodiment, the extension and retraction of the cylinder 6 drives the connecting plate 1 to rotate through the bolt 5. The connecting plate 1 is rotatably mounted on the hinge shaft 3. The connecting plate 1 itself forms a lever structure. When the end of the connecting plate 1 close to the bolt 5 rotates, the support rod 2 swings. The support rod 2 and the protective door on the support rod 2 perform a fan-shaped motion together, controlling the opening and closing of the protective door.
[0026] The gate block 4 includes a first fixing plate and a second fixing plate. The first fixing plate is movably sleeved on the smooth section 52 and is located between the joint bearing rod 7 and the nut 53. One end of the second fixing plate is fixedly connected to the first fixing plate, and the other end is connected to the connecting plate 1. In this embodiment, when the bolt 5 is deformed by force, the gate block 4 needs to bear the force. Therefore, the first fixing plate is preferably rotatably connected to the smooth section 52 of the bolt 5 by a bearing.
[0027] A third fixing plate 43 is provided between the second fixing plate 42 and the connecting plate 1. A locking member 8 is provided between the third fixing plate 43 and the connecting plate 1. One end of the third fixing plate 43 is fixedly connected to the second fixing plate 42, and the other end has a through hole for the locking member 8 to pass through. The connecting plate 1 has a threaded hole for the locking member 8 to pass through. One end of the locking member 8 passes through the through hole and the threaded hole in sequence, thereby locking and fixing the third fixing plate 43 and the connecting plate 1. In this embodiment, the first fixing plate 41 and the second fixing plate 42 are integrally formed, and the second fixing plate 42 and the third fixing plate 43 are integrally formed, forming a continuous 90° bending structure. The locking member 8 is also a bolt 5. In this embodiment, there are two locking members 8, and there are also two threaded holes and two through holes.
[0028] Working principle:
[0029] The cylinder 6 extends and retracts, causing the connecting plate 1 to rotate around the hinge axis 3 via the bolt 5. This, in turn, causes the support rod 2 and the protective door mounted on the support rod 2 to swing, thereby controlling the opening and closing of the protective door. When the cylinder 6 lifts the bolt 5, both ends of the bolt 5 are subjected to force. Compared to the existing connection method of the bolt 5, the bolt 5 is changed from a single-sided connection to a double-sided force-bearing method. The force borne by the root of the bolt 5 is only half of the original, which improves the problem of force concentration, greatly extends its service life, and prevents the safety hazard of the protective door falling and injuring people due to bolt 5 breakage.
[0030] Example 2
[0031] like Figure 5-6 As shown, the difference between this embodiment and the first embodiment is that an auxiliary support assembly is provided between the second fixing plate 42 and the connecting plate 1. The auxiliary support assembly includes a support plate 10 and a support member 11. The support plate 10 is fixed on the connecting plate 1 and is located below the second fixing plate 42. The support member 11 is threaded through the support plate 10. The bottom of the second fixing plate 42 is provided with a groove 9, and the top of the support member 11 abuts against the groove 9.
[0032] In this embodiment, a round rod 12 is welded to the side of the nut 53 away from the screw, and the first fixing plate 41 of the gate block 4 is fitted onto the round rod 12. With this structural design, the installation, disassembly, maintenance and replacement of the gate block 4 are more convenient.
[0033] In this embodiment, the support member 11 also uses bolts 5. By setting the support member 11 and the support plate 10, an auxiliary support is formed for the gate block 4, making the gate block 4 more stable when bearing force and extending the service life of the gate block 4.
