Description

Technical field:

[0001] The utility model relates to the technical field of accumulator pressure-maintaining devices during tire vulcanization, in particular to an accumulator pressure-maintaining device for a vulcanizing tank which can save electricity and has stable operation, reasonable structure and simple operation. Background technology:

[0002] The pressure-maintaining system of the vulcanization tank is composed of a high-pressure water pump and a pipeline connected to the high-pressure water pump. During the vulcanization process, the power water is sent to the water cylinder of the vulcanization tank in the workshop through the high-pressure water pump. The high-pressure water pump has been running for a long time to maintain the pressure of the vulcanization system, which will lead to waste of electric energy and high pressure. There is a danger. How to maintain the mold clamping pressure in the vulcanization system without the high-pressure water pump running for a long time is the problem to be solved at present. Summary of the invention:

[0003] The utility model aims at the shortcomings and deficiencies in the prior art and proposes an accumulator pressure-maintaining device for a vulcanizing tank which can maintain the mold clamping pressure in a vulcanizing system and does not require a high-pressure water pump to run for a long time.

[0004] The utility model achieves this through the following measures:

[0005] An accumulator pressure-maintaining device for a vulcanizing tank is characterized in that it is provided with an accumulator counterweight barrel, a base, an accumulator buffer pad, and an accumulator water cylinder, wherein the accumulator counterweight barrel is coaxially arranged above the accumulator water cylinder, the accumulator water cylinder and the accumulator buffer pad are both arranged on the base, a travel switch lever is arranged on the side of the accumulator counterweight barrel, and the travel switch assembly is installed on the side of the accumulator counterweight barrel and the accumulator water cylinder through a bracket, and the travel switch assembly is provided with a water pump closing travel switch and a water pump opening travel switch which are arranged in sequence from top to bottom along the bracket, and the water pump is provided with a water pump closing travel switch and a water pump opening travel switch. The travel switch for closing the pump and the travel switch for starting the water pump are respectively connected to the control circuit of the high-pressure water supply pump. A power water tank is also provided for replenishing water into the system. Two or more high-pressure water supply pumps and a check valve are arranged on the pipeline between the power water tank and the accumulator water cylinder. The accumulator water cylinder is connected to the workshop sulfide water cylinder through a pipeline. The travel switch lever on the side of the accumulator counterweight barrel is between the travel switch for closing the water pump and the travel switch for starting the water pump when the pressure between the workshop sulfide water cylinder and the accumulator water cylinder is balanced.

[0006] The utility model provides four high-pressure water replenishment pumps on the pipeline between the power water tank and the accumulator water cylinder, which are No. 1 high-pressure water pump, No. 2 high-pressure water pump, No. 3 high-pressure water pump and No. 4 high-pressure water pump in sequence, and the travel switch for closing the No. 3 and No. 4 high-pressure water pumps, the travel switch for closing the No. 1 high-pressure water pump, the travel switch for closing the No. 2 high-pressure water pump, the travel switch for opening the No. 1 high-pressure water pump, the travel switch for opening the No. 2 high-pressure water pump, and the travel switch for opening the No. 3 and No. 4 high-pressure water pumps are arranged in sequence from top to bottom in the travel switch assembly accordingly, so that according to the water level in the workshop vulcanization tank, the No. 1 high-pressure water pump and the No. 2 high-pressure water pump are opened in time and in sequence for water replenishment. If there is still a shortage of water, the No. 3 and No. 4 high-pressure water pumps are opened at the same time thereafter.

[0007] The accumulator buffer pad of the utility model is arranged on the base in a centrally symmetrical manner around the accumulator counterweight barrel, and is used for buffering the pressure when the accumulator counterweight barrel descends.

[0008] The utility model also provides a travel switch connected to the alarm circuit in the travel switch assembly. The alarm circuit adopts an audible and visual alarm circuit, and a travel switch for alarm activation and a travel switch for alarm closure are provided in the travel switch assembly accordingly. The travel switch for alarm activation is arranged between the travel switch for activation of the first high-pressure water pump and the travel switch for activation of the second high-pressure water pump, and the travel switch for alarm closure is arranged between the travel switch for activation of the first high-pressure water pump and the travel switch for closure of the second high-pressure water pump.

[0009] During the operation of the utility model, the power water will be sent into the water cylinders of the workshop vulcanization system and the accumulator counterweight barrel through the high-pressure water pump. When the accumulator counterweight barrel rises to the position of the third stroke switch above, the high-pressure water pump will stop running, and the one-way check valve at the outlet of the high-pressure water pump will be closed. The mold clamping pressure in the vulcanization system will be maintained by the weight of the accumulator counterweight barrel itself. If there is a slight leakage in the water cylinder of the vulcanization tank, the accumulator counterweight barrel will drop and touch the first stroke switch below. When a high-pressure water pump is turned on, the pressure will rise to a certain position and touch the third stroke switch above, stopping the high-pressure water pump. This cycle will continue until the vulcanization is completed, and the tank will be filled and vulcanized again after the maintenance worker has dealt with the leakage point.

[0010] The beneficial effect of the utility model is that the high-pressure water pump does not need to run for a long time during the normal vulcanization process, which not only achieves the effect of energy saving, but also can use the weight of the accumulator itself to maintain the mold pressure of the vulcanization system, and will not cause danger due to excessive pipeline pressure.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Example:

[0017] As attached Figure 1 As shown, this example proposes an accumulator pressure-maintaining device for a vulcanizing tank, which is provided with an accumulator counterweight barrel 1, in which a relative number of counterweight irons 22 are installed to maintain the weight of the accumulator counterweight barrel 1, the accumulator counterweight barrel 1 is connected to the accumulator fixed bracket 21, the accumulator fixed bracket is connected to the water cylinder piston rod 20, the interval between the travel switch 3 5 and the travel switch 4 6 is 100CM, and the interval between the other travel switches is 20CM. When the accumulator counterweight barrel 1 drops to the travel switch 1 3, the No. 1 high-pressure water Pump 14 starts to run, and the power water in the power water tank 13 enters the high-pressure water pump through the water outlet, and then enters the accumulator water cylinder 2 after the high-pressure water pump outlet gate valve 18 is opened. The accumulator counterweight barrel 1 is pushed up by the pressure in the accumulator water cylinder 2. When it touches the travel switch 6 8, the No. 1 high-pressure water pump 14 is turned off, and the one-way check valve 12 is closed at the same time. The weight of the accumulator counterweight barrel 1 will maintain the pressure of the accumulator water cylinder 2 and the vulcanization tank water cylinder 11 to the workshop, ensuring the system pressure of the vulcanization tank mold clamping;

[0018] If a slight leak occurs in the workshop vulcanization system and the pressure in the system cannot be maintained, the accumulator weight barrel 1 will drop and repeat the above cycle until the leak is resolved and normal operation is resumed;

[0019] If a slightly heavy leak occurs in the workshop vulcanization system, the pressure in the system cannot be maintained, and the accumulator counterweight barrel 1 will drop. When it touches the travel switch 1 3, the No. 1 high-pressure water pump 14 starts to run. Because the leak is larger than before, the accumulator counterweight barrel 1 will continue to drop slowly. When it touches the travel switch 3 5, the alarm light in the operation room will start to alarm, and the operator will notify the workshop shift supervisor and the vulcanizer in the production workshop to immediately find the cause of the leak. In the process of notifying relevant personnel, the accumulator counterweight barrel 1 will continue to drop slowly until it touches the travel switch 5 7, and the No. 2 high-pressure water pump 15 will run at the same time. The accumulator counterweight barrel 1 will rise until it touches the travel switch 2 4, and the alarm light will stop alarming. It will continue to rise until it touches the travel switch 4 6, and the No. 2 high-pressure water pump 15 will be turned off. At this time, if the workshop solves the leakage problem, the accumulator counterweight barrel 1 will continue to rise until it touches the travel switch 6 8 and then stop the No. 1 high-pressure water pump 14;

[0020] If the workshop fails to solve the leakage problem, the accumulator weight barrel 1 will drop and repeat the above cycle until the leakage problem is solved and normal operation is restored;

[0021] If there is a serious leak in the workshop vulcanization system, the pressure in the system cannot be maintained, and the accumulator counterweight barrel 1 will drop. When it touches the travel switch 13, the No. 1 high-pressure water pump 14 starts to run. Because the leak is larger than before, the accumulator counterweight barrel 1 will continue to drop. When it touches the travel switch 35, the alarm light in the operation room starts to alarm, and the operator will notify the workshop duty manager and the vulcanizer in the production workshop to immediately find the cause of the leak. In the process of notifying relevant personnel, the accumulator counterweight barrel 1 will continue to drop. After touching the travel switch 57, the No. 2 high-pressure water pump 15 starts running at the same time. At this time, due to the serious leak, the accumulator counterweight barrel 1 will continue to descend and touch the travel switch 79, the No. 3 high-pressure water pump 16 and the No. 4 high-pressure water pump 17 will run at the same time, and the four high-pressure water pumps will run at the same time. The accumulator counterweight barrel 1 will rise until it touches the travel switch 24, and the alarm light will stop alarming. It will continue to rise until it touches the travel switch 46, and the No. 2 high-pressure water pump 15 will be turned off. At this time, if the workshop solves the leakage problem, the accumulator counterweight barrel 1 will continue to rise until it touches the travel switch 68, and then stop the No. 1 high-pressure water pump 14. After touching the travel switch 810, turn off the No. 3 high-pressure water pump 16 and the No. 4 high-pressure water pump 17 and resume normal operation. If the workshop does not solve the leakage problem, the accumulator counterweight barrel 1 will descend and repeat the above cycle until the leakage problem is solved and normal operation is resumed;

[0022] In this example, the accumulator buffer pad 19 is a buffer device used to slowly lower the accumulator counterweight barrel 1 onto the accumulator buffer pad 19 when the accumulator is being repaired, or to quickly lower the accumulator when an abnormal situation occurs to prevent the accumulator counterweight barrel 1 from colliding with the bottom bracket.

When SQ1 is touched, the KM1 coil is energized, the No. 1 high-pressure water pump runs, the KM1 auxiliary contact is connected, and the No. 1 high-pressure water pump running indicator light is on. When SQ2 is touched, the KM1 coil is de-energized and the No. 1 high-pressure water pump stops running. When SQ3 is touched, the KM2 coil is energized, the No. 2 high-pressure water pump runs, the KM2 auxiliary contact is connected, and the No. 2 high-pressure water pump running indicator light is on. When SQ4 is touched, the KM2 coil is de-energized and the No. 2 high-pressure water pump stops running. When SQ5 is touched, the KM3KM4 coils are energized, the No. 3 and No. 4 high-pressure water pumps run, the KM3KM4 auxiliary contacts are connected, and the No. 3 and No. 4 high-pressure water pump running indicators are on. When SQ5 is touched, the KM3KM4 coils are de-energized and the No. 3 and No. 4 high-pressure water pumps stop running. When SQ7 is touched, the KM5 coil is energized, the accumulator low-level alarm starts, the KM5 auxiliary contact is connected, and the accumulator low-level alarm indicator light comes on. When SQ7 is touched, the KM5 coil loses power and the accumulator low-level alarm stops.
