[0002] The design of biopharmaceutical equipment is becoming more and more integrated and modular, resulting in a more compact layout of the equipment and less available space. General biopharmaceutical equipment is designed with a manhole, which is an opening on the equipment that allows workers to enter and exit the equipment for installation, maintenance, feeding and other operations. The feeding barrel is covered with a manhole cover, and opening or closing the manhole cover is to open or close the manhole, and the operation of opening or closing the manhole cover can be completed by a mechanical device. The pneumatic quick-opening manhole with application number 201620796871.3 has a transmission shaft that drives the flap to rotate, but it has too many hinged structures, the flap action occupies a large space, and the telescopic stroke of the pneumatic feeding barrel is large. After long-term use, too many hinged structures are easily damaged, causing the manhole cover to be inaccurately positioned. Utility Model Content

[0003] In view of the shortcomings of the related art that the pneumatic quick-opening manhole has too many hinged structures, which are easily damaged after long-term use, resulting in inaccurate alignment of the manhole cover and the barrel, the present application provides a manhole device that opens the cover and feeds materials by means of a horizontal rotating device in conjunction with a lifting device.

[0004] To achieve the above objectives, this application provides the following technical solutions.

DETAILED DESCRIPTION

[0026] Some embodiments of the horizontal rotating manhole opening device of the present application are described in detail below in conjunction with the accompanying drawings.

[0027] Please refer to Figure 1 A horizontal rotating manhole opening device comprises a manhole cylinder section 1, a manhole cover 2, a lifting device 3 and a horizontal rotating device 4.

[0028] The horizontal rotating device 4 includes a rotating driver 41 , a rotating shaft 42 , a connecting arm 43 and a fixing seat 44 .

[0029] The fixing seat 44 connects the rotary driver 41 and the outer side wall of the manhole barrel section 1. The fixing seat 44 and the rotary driver 41 can be fixed by bolt connection, and the fixing seat 44 and the outer side wall of the manhole barrel section 1 can be fixed by welding.

[0030] The rotating shaft 42 is connected to the output end of the rotating driver 41. The rotating shaft 42 can be in a vertical direction, and the manhole barrel section 1 can be an upright cylindrical barrel. Preferably, the rotating shaft 42 and the axis of the manhole barrel section 1 are parallel. The manhole cover 2 is a dome that fits the opening at the upper end of the manhole barrel section 1, and can be a part of a spherical body after cross-cutting a sphere.

[0031] One end of the connecting arm 43 is fixed to the rotating shaft 42, and the other end is fixed to the lifting device 3. The main body of the connecting arm 43 can be a section of inclined rising inclined rod plus a section of horizontal rod, the starting end of the inclined rod is fixed to the rotating shaft 42, and the end of the horizontal rod is connected to the lifting device 3.

[0032] The lifting device 3 includes a lifting drive 31 and a connecting seat 32. The other end of the connecting arm 43 is fixed to the lifting drive 31. The connecting arm 43 is fixedly connected to the main body of the lifting drive 31. The connecting seat 32 connects the output end of the lifting drive 31 and the top center position of the manhole cover 2. The connecting seat 32 and the manhole cover 2 can be detachably connected by bolts.

[0033] Please refer to Figure 2 One state of the horizontal rotating manhole opening device is that the horizontal rotating device 4 drives the manhole cover 2 to the top of the manhole barrel section 1. At this time, the lifting device 3 can be started to lower the manhole cover 2 to close the manhole, or the horizontal rotating device 4 can be started to remove the manhole cover 2 to facilitate adding materials into the manhole cover barrel section 2.

[0034] Please refer to Figure 1 Another state of the horizontally rotating manhole opening device is that the lifting device 3 drives the manhole cover 2 to close the upper port of the manhole cylinder section 1, and other conditions are adjusted so that the substances in the manhole cylinder section 1 can react, etc.

[0035] When using this equipment, the manhole cover 2 is driven to rise or fall by the lifting device 3, so that the manhole cover 2 can cover the upper opening of the manhole cylinder section 1 or open the opening, and the manhole cover 2 at a high position can be driven to move to the top of the manhole cylinder section 1 by the horizontal rotating device 4 to block the manhole, or the manhole cover 2 at a high position can be driven to move out of the top of the manhole cylinder section 1 to perform installation, maintenance, feeding and other operations. This equipment does not use an articulated structure, and can still maintain good movement accuracy after long-term use, and the alignment of the manhole cover 2 and the manhole cylinder section 1 remains long-term and accurate.

[0036] Please refer to Figure 3 In order to enhance the operational safety and reliability of the equipment, the rotation angle of the manhole cover 2 can be limited, and the horizontal rotating manhole opening device further includes a limiting device 5. The limiting device 5 includes a first limiting block 51, a second limiting block 52 and a rotating member 53. The horizontal rotating device 4 also includes a bearing 45. The bearing 45 is sleeved on the rotating shaft 42, and the inner circumference of the bearing 45 is fixedly connected to the rotating shaft 42. The outer circumference of the bearing 45 is fixed to the manhole barrel section 1, so that the limiting device 5 can be installed on the outer circumference of the bearing 45. The first limiting block 51 and the second limiting block 52 are both fixed on the outer circumference of the bearing 45, and the rotating member 53 is fixed on the rotating shaft 42, and the rotating member 53 is set to move between the first limiting block 51 and the second limiting block 52. The limiting device 5 limits the rotation angle of the connecting arm 43, that is, limits the rotation route of the manhole cover 2, enhances the safety of the equipment, and is also conducive to the alignment of the manhole cover 2 and the manhole barrel section 1.

[0037] In order to enhance the rotational stability and accuracy of the connecting arm 43, the limiting device 5 is also provided to include a magnet 54, the magnet 54 is mounted on the first limiting block 51, and the rotating member 53 is made of ferromagnetic material. When the rotating member 53 contacts the magnet 54, the manhole cover 2 is located directly above the manhole barrel section 1. When the manhole cover 2 is to be covered, the connecting arm 43 is driven to rotate, and the rotating member 53 is adsorbed by the magnet 54, i.e., it is positioned and not easy to shake, so that the alignment of the manhole cover 2 and the manhole barrel section 1 is more stable and accurate. Since the suction force of the magnet 54 on the larger connecting arm 43 is relatively small, to remove the rotating member 53 from the magnet 54, it is only necessary to drive the rotary driver 41 to detach the rotating member 53.

[0038] The central angle between the first limiting block 51 and the second limiting block 52 and the axis of the bearing 45 is 90°, so that the operation of the equipment is stable, safe and reliable.

[0039] In order to fix the connecting arm 43 on the rotating shaft 42, a key slot can be provided on the rotating shaft 42, and a key bar can be installed in the key slot. The connecting arm 43 is fitted on the key bar, so that the connecting arm 43 and the rotating shaft 42 are connected and fixed. This connection structure enables the connecting arm 43 and the rotating shaft 42 to form a detachable fixed connection, that is, they can rotate synchronously and can be easily installed and removed.

[0040] In addition to the above keyway connection, the rotating shaft 42 and the connecting arm 43 can also be fixed by welding.

[0041] In order to enhance the sealing effect of the manhole cover 2 and the manhole barrel section 1, a sealing ring 6 is embedded in the upper periphery of the manhole barrel section 1. The periphery of the manhole cover 2 can be adapted to be pressed on the sealing ring 6 to form a sealed connection.

[0042] The rotary driver 41 may be a rotary cylinder or a servo motor, which outputs a rotary driving force.

[0043] The lifting driver 31 can be a telescopic cylinder or a screw motor, which can output telescopic pushing force.

[0044] In the horizontal rotating manhole opening device of this embodiment, the lifting device 3 lifts or lowers the manhole cover 2, and the horizontal rotating device 4 drives the manhole cover 2 to rotate horizontally to open. The bearing 45 and the connecting arm 43 are equipped with limit blocks to limit the rotation angle of the manhole cover 2, so that the manhole cover 2 and the manhole cylinder section 1 are accurately aligned. The device does not use a hinged structure, has little wear and tear after long-term use, and has a long service life.
