In this document, directional terms such as "front" and "rear" are used interchangeably with... Figure 1 The orientation is used as a reference. Figure 1 The left and right directions are the horizontal width directions of the fan frame.

[0038] Example 1:

[0039] Reference Figures 1-8 As shown, a pressure vessel system includes a glass production conveying bridge, a feeding end 500, a pressure vessel body 200, and a transmission structure 400 disposed at the bottom of the inner cavity of the pressure vessel body 200. The pressure vessel body 200 has an openable feed inlet 202, and a transmission gear 201 is disposed on the side of the transmission structure 400 near the feed inlet 202, and the transmission gear 201 can mesh with a drive gear 253. The feeding end 500 can transfer the glass cart 300 to the transfer mechanism 2 of the conveying bridge 100. The transfer mechanism 2 can transfer the glass cart 300 to the transfer structure 400 of the pressure vessel body 200. The conveying bridge 100 can rotate and rise or fall along the rotating end 21. When the feed port 202 of the pressure vessel body 200 is opened, the conveying bridge 100 is raised to make way. When the pressure vessel body 200 is opened, the conveying bridge 100 is lowered to cooperate with the transportation of the glass cart 300. After the transportation is completed, the conveying bridge 100 is raised to make way.

[0040] The embodiment provides a conveying swing bridge for glass production, which comprises a swing bridge frame 1 located outside a gas pressure kettle. A transmission mechanism 2 is installed on the swing bridge frame 1, and a glass vehicle 300 is located on the transmission mechanism 2. The transmission mechanism 2 has a rotating end 21 and a free end 22, and the free end 22 can be engaged with a transmission gear 201 in the gas pressure kettle body 200. A power source 3 is arranged at the rotating end 21 of the transmission mechanism 2, and the power source 3 can drive the transmission mechanism 2 to transport the glass vehicle 300 into the gas pressure kettle body 200 and cooperate with the transmission gear 201 of the gas pressure kettle body 200. A lifting mechanism 4 is located at one end of the swing bridge frame 1 close to the power source 3 and is hinged to the swing bridge frame 1. The lifting mechanism 4 can drive the swing bridge frame 1 to rotate upwards along the axis of the power source 3 to lift the swing bridge frame 1.

[0041] In the embodiment, the conveying swing bridge for glass production and the gas pressure kettle system thereof are provided. The swing bridge frame, the transmission mechanism installed on the swing bridge frame and the transmission gear of the gas pressure kettle body are engaged to form a structure. The transmission mechanism is driven by the power source to drive the transmission gear of the gas pressure kettle body to rotate to drive the transmission in the gas pressure kettle body, so that the glass vehicle is transported into the gas pressure kettle body. The manual pushing into the gas pressure kettle body and the manual walking out of the gas pressure kettle body are avoided, a large amount of time is saved, and the occurrence of safety accidents caused by manual operation is avoided. Moreover, the lifting mechanism is hinged to the outer wall of the swing bridge frame. The conveying swing bridge as a whole is lifted upwards or falls along the rotating end to cooperate with the transportation of the glass vehicle towards the gas pressure kettle body and the closing of the gas pressure kettle body for work. The waiting time of the glass vehicle entering and leaving the gas pressure kettle can be greatly shortened, the utilization rate of the gas pressure kettle is improved, and the production capacity is improved.

A set of equipment can safely and quickly transport the glass vehicle into or out of the gas pressure kettle without affecting the opening of the gas pressure kettle body, and automatic production of the gas pressure kettle and the transmission line in front of the kettle is realized.

[0042] Specifically, it is shown as follows Figure 4 and Figure 5 As shown in the figure, since the gas pressure kettle body 200 is in a high-temperature and high-pressure sealed state, the transmission in the kettle has no active transmission power, and therefore external equipment is used to provide power. When the conveying swing bridge 100 falls, the chain 23 transmission mechanism is in a running state, and the engagement of the driving gear 253 of the conveying swing bridge 100 and the transmission gear 201 in the kettle can be completed at the same time that the conveying swing bridge 100 falls. When the swing bridge falls to a horizontal state, the gears are completely engaged. The broken line detection mechanism is mainly used for detecting whether the conveying line is broken or the cable is used up. The laser sensor can immediately capture the broken line information, and the broken line is clamped by the PLC control line clamping mechanism, so that the line disc can be replaced. The control system is prior art, and will not be described in detail here.

[0043] In the embodiment, the swing bridge frame 1 comprises two longitudinally arranged strip channel steels 11, a plurality of transversely arranged strip channel steels 12 arranged between the two longitudinally arranged strip channel steels 11, and the two ends of the transversely arranged strip channel steels 12 are welded with the two longitudinally arranged strip channel steels 11. The two ends of the two longitudinally arranged strip channel steels 11 are respectively sleeved with a "U"-shaped channel steel 13. The two "U"-shaped channel steels 13 of the rotating end 21 are respectively provided with a coaxially arranged first through hole 14, and the two "U"-shaped channel steels 13 of the free end 22 are respectively provided with a second through hole 15. The "U"-shaped channel steel 13 and the end of the longitudinally arranged strip channel steel 11 form a receiving groove 16. The swing bridge frame 1 further comprises a fixing frame 17 arranged at the rotating end 21, and the fixing frame 17 is arranged below the first through hole 14 and extends outward in the transverse direction to form a platform for fixing and placing the power source 3. As shown in Figure 8 The swing bridge frame 1 is mainly used for bearing the entire device and the glass car 300 above, so the frame structure needs to be simple, meet the strength requirement, be light in weight, and not be deformed obviously to affect the transmission of the chain 23. Therefore, the swing bridge frame 1 is made of channel steel, all the welds are full-welded, and the burrs are removed to eliminate the stress.

[0044] Further, the transmission mechanism 2 comprises a chain 23, a driving transmission structure 24 and a driven transmission structure 25. The driving transmission structure 24 is partially arranged in the two receiving grooves 16 of the rotating end 21, is arranged between the two "U"-shaped channel steels 13 of the rotating end 21 and extends out of the two "U"-shaped channel steels 13 at two ends, is connected with the power source 3 at one end and is connected with the "U"-shaped channel steel 13 through a bearing at the other end. The driven transmission structure 25 is partially arranged in the two receiving grooves 16 of the free end 22, is arranged between the two "U"-shaped channel steels 13 of the free end 22 and extends out of the two "U"-shaped channel steels 13 at two ends and is arranged on the "U"-shaped channel steel 13 through a bearing. The chain 23 has two chains, and the two ends of the two chains 23 are sleeved on the driving transmission structure 24 and the driven transmission structure 25 on the two sides respectively for driving the driving transmission structure 24 and the driven transmission structure 25. The schematic diagram is as follows Figures 2-5 As shown in FIGS. 6 and 7, the swing bridge transmission adopts a 24A roller chain, which has the characteristics of simple structure, strong bearing capacity, smooth operation and low maintenance cost. The power source 3 (motor reducer) drives the main transmission shaft 242 to rotate, the main transmission shaft 242 drives the first sprocket 241 to transmit power to the chain 23, and the glass car 300 is driven to move forward or backward through the circular motion of the chain 23 (see FIG. 8). Figure 1Further, the driving transmission structure 24 includes two first sprockets 241 arranged in the accommodating groove 16 of the rotating end 21 respectively, and the two first sprockets 241 are engaged with one end of the two chains 23 respectively, the two first sprockets 241 are connected by a main transmission shaft 242, and the main transmission shaft 242 is connected with the power source 3.

[0045] Further, the driven transmission structure 25 includes two second sprockets 251 arranged in the accommodating groove 16 of the free end 22 respectively, and the two second sprockets 251 are engaged with the other end of the two chains 23 respectively, the two second sprockets 251 are connected by a driven transmission shaft 252, and the driven transmission shaft 252 is externally provided with a driving gear 253, and the driving gear 253 is used to engage with the transmission gear 201 in the autoclave body 200.

[0046] Further, the transmission mechanism 2 further includes a tension sprocket 26 detachably mounted on the rack. The tightness of the chain 23 can be adjusted to better transport.

[0047] Referring to Figure 6 As shown, it includes an axle 5 and a bushing 6, so that the chain 23 is more flexible to be installed in the accommodating groove 16, and the chain 23 is adjusted.

[0048] Further, the lifting mechanism 4 is a gas cylinder. Specifically, as shown Figure 7 As shown, the lifting mechanism 4 of the swing bridge adopts a large-diameter cylinder of FESTO to push, because the mechanism is auxiliary equipment for assisting the glass car to enter and exit the autoclave, so the auxiliary time used for lifting the equipment each time is reduced as much as possible, which can effectively improve the beat of the entire automatic process, so that the large-diameter cylinder can provide sufficient pushing force and can complete the lifting action in a very short time.

[0049] At present, several manual trolleys are mostly used in the market to cooperate with the transition car to send the glass car into the autoclave. In order to reduce the resistance of the trolley pushed by the workers, steel rails are usually laid in the workshop, the transition car is also equipped with the same type of steel rails, and the autoclave is also laid with steel rails. The glass car 300 adopts special track steel wheels, and the full load glass car 300 is manually pushed into the autoclave body 200. All the above steps are manually operated, so it is necessary to confirm whether there is a person in the autoclave body 200 and the door opening 202 when the autoclave body 200 is opened or closed, so as to avoid safety accidents. The transmission line docking of the autoclave body 200 by the device can effectively improve the safety and efficiency of the glass car entering the autoclave, and can realize automatic production by cooperating with the transmission line outside the autoclave and the transmission line inside the autoclave.

[0050] The purpose of the embodiment is to provide a set of equipment which can safely and quickly send or push the glass car 300 into or out of the autoclave body 200 without affecting the opening of the autoclave, and realize the automatic production of the autoclave body 200 and the pre-autoclave conveying line.

[0051] First, the conveying swing bridge 100 is in the raised state, at this time, the space in front of the autoclave body 200 door is not blocked, the operator can one-key open the door, the swing bridge is lowered after the autoclave door is opened, in the process of lowering, the motor drives the chain 23 to rotate, when the conveying swing bridge 100 is lowered to the horizontal state, the front gear (driving gear 253) of the conveying swing bridge 100 is engaged with the transmission gear 201 in the autoclave, at this time, the power source 3 (motor) of the conveying swing bridge 100 rotates to drive the transmission in the autoclave to run simultaneously.

[0052] The glass car 300 loaded with glass can pass through the pre-autoclave conveying line, enter the autoclave body 200 through the conveying swing bridge 100, when all the glass cars 300 enter the autoclave body 200, the conveying swing bridge 100 is raised, at this time, the operator can one-key realize the closing of the autoclave body 200 door, and according to the production process, the autoclave body 200 starts to work.

[0053] When the autoclave completes production, the high-temperature air and pressure are excluded, the operator opens the autoclave door, the swing bridge is lowered and is connected with the conveying line in the autoclave at the same time, the glass car in the autoclave which completes production is conveyed to the conveying line outside the autoclave, and the production of the next process is carried out, at this time, other glass cars to be produced can continue to enter the autoclave through the swing bridge for production.

[0054] The above production process is circular, which can greatly shorten the waiting time of the autoclave for entering and exiting the glass car 200, improve the utilization rate of the autoclave, and improve the production capacity. Since the operator only needs to perform button operation in the whole production process, the labor cost is reduced and the safety risk of the operator directly entering the autoclave is reduced.
