Description

TECHNICAL FIELD

[0002] In the process of loading automobile tank car, the vertical posture of loading crane pipe and the sealing of jar mouth are two key problems. At present, the vertical pipe of loading crane pipe mainly relies on its own gravity to keep drooping, thereby maintaining the vertical state to the ground. However, this way has many disadvantages:

[0003] Firstly, with the increase of service time, the vertical pipe may gradually deviate from the vertical state due to gravity, resulting in that the vertical pipe no longer maintains the vertical state to the ground. The non-vertical vertical pipe not only reduces the loading efficiency, but also may collide with the loading jar mouth, thereby causing problems such as jar mouth deformation, affecting the safe use of tank car.

[0004] Secondly, the non-vertical vertical pipe also affects its normal entry into the jar mouth of tank car, resulting in phenomena such as missing loading, wrong loading and the like in the loading process, further reducing the loading efficiency. In addition, in the loading process, the jar mouth is usually in an open state, which will cause toxic and harmful gases to leak out from the jar mouth. These gases not only pose a threat to the health of the operating personnel, but also pollute the surrounding environment and destroy the ecological environment.

[0005] In view of the above problems, although there are some improvement measures in the prior art, such as adding counterweight blocks or setting simple sealing devices on the vertical pipe, these methods still have limitations. For example, the counterweight blocks may fail due to long-term use, resulting in unstable vertical posture of the vertical pipe; and the simple sealing device is easily affected by pipeline pressure and vibration during the loading process, the sealing effect is difficult to guarantee, and the problem of leakage of toxic and harmful gases cannot be effectively solved.

[0006] Therefore, an apparatus capable of effectively maintaining the vertical posture of the vertical pipe and realizing the sealing of the jar mouth is urgently needed to improve the efficiency and safety of loading automobile tank car, reduce the leakage of toxic and harmful gases, protect the health of the operating personnel and the environment.

[0007] In view of the problems in the related art, the utility model provides a vertical pipe posture keeping jar mouth airtight device. UTILITY MODEL CONTENTS

The present application can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in the present specification based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0026] The present application aims at the defects of the prior art and provides a vertical pipe attitude holding tank opening sealing device.

[0027] Example 1

[0028] The present application provides a vertical pipe attitude holding tank opening sealing device, as shown in the accompanying drawings, which comprises a vertical pipe 1 of a loading crane pipe, an outer arm pipe 2, a first attitude plate 3, a second attitude plate 4, an attitude holding pull rod 5, and a tank opening sealing cap 6. Figure 1

[0029] In the present example, the vertical pipe 1 and the outer arm pipe 2 can adopt the existing structure.

[0030] The outer arm pipe 2 is provided with a first rotary joint 7 and a second rotary joint 8 at both ends, respectively. The first rotary joint 7 of the outer arm pipe 2 can be connected with the inner arm of the loading crane pipe through a rotary support, and the second rotary joint 8 of the outer arm pipe 2 is connected with the vertical pipe 1. The connection mode can refer to the prior art, and will not be described in detail here. In the present example, a driving system such as an electric or pneumatic driving cylinder is further provided on the outer arm pipe 2, so as to control the up-and-down swing of the outer arm pipe 2 under the action of the rotary support through the driving cylinder.

[0031] The first attitude plate 3 and the second attitude plate 4 have the same length. The outer arm pipe 2 is further connected with the first attitude plate 3 perpendicularly and movably through the first rotary joint 7, and is further connected with the second attitude plate 4 perpendicularly and movably through the second rotary joint 8. The end of the second attitude plate 4 close to the outer arm pipe 2 is fixedly connected with the vertical pipe 1 through a butt flange, so as to make the first attitude plate 3 and the second attitude plate 4 parallel to the vertical pipe 1. The connection mode can refer to the prior art, and will not be described in detail here.

[0032] ​The length of the posture maintaining pull rod 5 is the same as the length of the outer arm pipeline 2 and is parallel to each other, and the two ends of the posture maintaining pull rod 5 are movably connected with the first posture plate 3 and the second posture plate 4 respectively by means of hinging or the like, so that the first posture plate 3, the second posture plate 4, the outer arm pipeline 2 and the posture maintaining pull rod 5 form a parallelogram structure, and when the outer arm pipeline 2 swings up and down, the vertical pipe 1 can always maintain a vertical posture while moving up and down.

[0033] In the embodiment, the first posture plate 3, the second posture plate 4 and the posture maintaining pull rod 5 can be made of high-strength and light-weight materials to improve the durability and stability of the device.

[0034] The tank opening sealing cap 6 has an inverted circular truncated cone structure, and a through opening adapted to the vertical pipe 1 is formed in the middle of the tank opening sealing cap 6, so that the tank opening sealing cap 6 is sleeved on the outside of the vertical pipe 1 near the bottom, and is used for sealing cooperation with the tank opening of the automobile. When the vertical pipe 1 is inserted into the tank opening of the automobile until the tank opening sealing cap 6 is tightly sealed with the periphery of the tank opening of the automobile, a sealing effect is achieved to avoid leakage of toxic and harmful gases.

[0035] The tank opening sealing cap 6 can be made of elastic sealing material and can automatically deform when subjected to pressure or vibration to fill the tiny gap between the tank opening and the sealing cap.

[0036] The tank opening sealing cap 6 is further provided with a negative pressure recovery pipeline joint 9 connected with an external negative pressure pump through a pipeline to balance the gas pressure in the tank car and recover toxic and harmful gases.

[0037] When the loading starts, the DCS control system starts the negative pressure pump to keep the gas pressure in the tank car negative to avoid leakage of toxic and harmful gases; and when the loading ends, the DCS control system stops the negative pressure pump.

[0038] The embodiment has the following beneficial effects:

[0039] 1. Stable posture of the vertical pipe: By increasing the posture plate and the pull rod on the vertical pipe and the outer arm pipeline of the loading crane respectively, a parallelogram structure is formed, so that the vertical pipe always maintains a vertical state when moving up, down, left and right. This stable posture of the vertical pipe can ensure that the vertical pipe smoothly and accurately enters the tank opening of the tank car, avoid loading difficulties and efficiency reduction caused by the inclination of the vertical pipe, and thus significantly improve the loading efficiency of the tank car.

[0040] 2. Reducing loading failure: The stability of the vertical pipe posture can also effectively reduce the loading failure caused by the collision and friction between the vertical pipe and the tank opening during the loading process, such as deformation of the tank opening and damage of the pipeline. This further ensures the smooth progress of the loading process, reduces the time consumed for failure shutdown and maintenance, and improves the continuity and efficiency of the loading operation.

[0041] 3. The tank mouth is sealed tightly: a tank mouth sealing cap is added to the vertical pipe part, and is tightly attached to the tank mouth of the tank truck, realizing the closed loading of the tank truck. This tight sealing method can effectively prevent toxic and harmful gases from leaking out of the tank mouth, avoiding the threat of gas leakage to the health of the operators and the surrounding environment, and ensuring the safety and environmental protection of the operation site.

[0042] 4. Negative pressure recovery of toxic gas: by setting a negative pressure recovery pipeline joint on the tank mouth sealing cap and connecting it with a negative pressure pump, the balance of the gas pressure in the tank truck during loading and the negative pressure recovery of toxic and harmful gases are realized. This not only avoids the sealing problem caused by the increase of the pressure in the tank, but also further prevents gas leakage through negative pressure suction, enhances the environmental protection effect, and reduces the pollution to the environment.

[0043] 5. Reduce equipment wear: the stability of the vertical pipe posture and the tightness of the tank mouth sealing can effectively reduce the collision and friction between the vertical pipe and the tank mouth during loading, reducing the degree of equipment wear. This helps to prolong the service life of key components such as loading crane pipe and tank mouth, reduces the frequency and cost of equipment replacement and maintenance, and saves operating costs for the enterprise.

[0044] Example Two

[0045] The vertical pipe posture sealing device provided in this embodiment is different from that of Example One in that:

[0046] The vertical pipe posture sealing device further comprises an intelligent sensing system, which includes a gyroscope and accelerometer sensor, a pressure sensor and a temperature sensor, and a control system.

[0047] In this embodiment, the gyroscope and accelerometer sensor can be installed on the first posture plate, the second posture plate, and the posture maintaining pull rod, for real-time monitoring of the posture and motion state of the vertical pipe. The pressure sensor and the temperature sensor are arranged at the part where the tank mouth sealing cap contacts the tank mouth of the automobile, and the pressure sensor can detect the sealing effect, and the temperature sensor can monitor the sealing state.

[0048] The above sensors are connected with the control system to realize real-time transmission and processing of data. The control system automatically adjusts the angle or position of the posture plate and the pull rod according to the signals fed back by the sensors, to maintain the vertical state of the vertical pipe; at the same time, according to the data of the pressure and temperature sensors, the position and pressure of the tank mouth sealing cap are automatically adjusted to ensure the sealing performance. The intelligent sensing system can also work cooperatively with the driving cylinder, automatically adjusting the swing angle and speed of the outer arm pipe according to the real-time monitoring data, to adapt to different loading needs. In addition, the control system can also seamlessly interface with the existing loading system, realizing data sharing and function cooperation, optimizing the loading process, and improving the loading efficiency and safety.

[0049] It should be noted that the gyroscope, accelerometer sensor, pressure sensor, temperature sensor and control system involved in the embodiment can be realized by using existing devices, and the specific implementation manner is not improved in the embodiment.

[0050] The embodiment has the following beneficial effects:

[0051] 1. Improve the reliability of the equipment: the structural design of the device is reasonable, the connection between the components is firm, and the real-time monitoring and automatic adjustment of the vertical pipe posture and the tank opening sealing state are realized through intelligent sensing technology and control system. This intelligent control method improves the reliability and stability of the equipment, reduces the risk of production interruption caused by equipment failure, and ensures the continuous and stable operation of the loading operation.

[0052] 2. Simplify the operation process: the device has high automation, and the operator only needs to perform simple initial debugging and starting operation, and the subsequent vertical pipe posture maintenance and tank opening sealing are automatically completed by the device. This greatly simplifies the loading operation process, reduces the labor intensity and operation difficulty of the operator, and improves the convenience of the operation.

[0053] 3. Reduce labor input: since the device can automatically maintain the vertical pipe posture and realize the tank opening sealing, the dependence on the operator is reduced, and the skill level requirement of the operator is reduced. Enterprises can reduce the training and recruitment cost of professional operators, and also reduce the loading accidents and losses caused by human operation errors.
