Description

Technical Field

[0001] This invention relates to the field of live-line working equipment technology, specifically to a temperature control device for an insulating hopper used in live-line working. Background Technology

[0002] Live-line work, especially line maintenance work performed at height using insulated boom trucks, places extremely stringent requirements on the safety protection of workers. According to operating procedures, workers must wear multiple layers of heavy insulated protective clothing to ensure personal safety. While this protective clothing provides necessary electrical insulation, its heavy and airtight nature also imposes an additional burden on the workers.

[0003] Meanwhile, high-altitude live-line work is usually carried out outdoors, inevitably facing harsh seasonal climate changes. In winter, workers must endure the bitter cold; while in summer, they must withstand the scorching heat. When heavy insulated protective clothing is combined with these extreme weather conditions, the problems become particularly prominent. In high temperatures, the heat and sweat generated by the body are difficult to dissipate, easily leading to rapid depletion of the worker's energy and even heatstroke; in extremely cold weather, despite wearing thick clothing, the extremities are still susceptible to frostbite, and body stiffness also affects the flexibility of operation.

[0004] The physical discomfort caused by both protective equipment and the natural environment directly affects the physiological and psychological state of workers. It not only reduces work comfort but, more importantly, makes it difficult for workers to concentrate and reduces their physical strength, thus increasing the risk of operational errors and posing serious safety hazards. Ultimately, this unfavorable working environment inevitably leads to a decrease in overall work efficiency. Therefore, a temperature control device for the insulated bucket used for live-line working is proposed to address these problems. Summary of the Invention

[0020] This invention provides a temperature control device for an insulating hopper used in live-line work. It has the following beneficial effects:

[0021] 1. This invention provides a simple and inherently safe bidirectional temperature control solution for an insulated bucket by utilizing the physical properties of vortex tubes. High-pressure pure gas delivered to the insulated bucket by the insulated conveying assembly directly enters the vortex tube in the temperature control assembly inside the bucket. The vortex tube requires no moving parts or electrical energy and relies on the high-speed rotation of the airflow itself to separate cold and hot airflows. Operators can selectively introduce either cold or hot airflow into the bucket space by operating the reversing valve. The structure is simple and reliable, avoiding the introduction of any potential electrical fault points or fire hazards in the high-pressure sensitive area of ​​the insulated bucket, greatly improving the reliability and safety of the device.

[0022] 2. In this invention, the power from the power take-off drives the second hydraulic pump, which in turn drives the hydraulic motor to rotate through pipelines. Finally, the hydraulic motor drives the air compressor to run, forming an independent power circuit dedicated to the preparation of compressed air. This does not occupy the oil circuit of the first hydraulic pump for the original boom movement, nor does it require drawing complex electrical energy from the vehicle. This ensures the stability and safety of the boom movement, while preventing the introduction of additional electrical risks to the temperature control system.

[0023] 3. This invention features an insulated conveying assembly that solves the safety problem of long-distance, all-angle conveying of high-pressure gas on an insulated boom. The high-pressure gas prepared by the air compressor is purified by a refrigerated dryer and a gas storage filter before entering the insulated conveying assembly, which consists of multiple sections of insulated gas pipes. The pipes of the insulated conveying assembly pass through the rotation center at the base and are laid along the internal channels of the lower boom, upper boom, and finally the insulated boom. This ensures that the conveying path of the high-pressure gas is compatible with the rotation, lifting, and extension movements of the boom. Furthermore, the use of insulating materials for isolation ensures that the insulation performance of the entire vehicle is not damaged during the gas delivery to the insulated bucket, thus ensuring the inherent safety of high-altitude live-line operations.

[0033] Please see the appendix Figure 2 -Appendix Figure 4 The insulated delivery assembly includes a first insulated air pipe 30 connected between the air compressor 24 and the refrigerated dryer 25. The first insulated air pipe 30 is used to deliver the high-pressure gas discharged from the air compressor 24. The insulating material can prevent leakage hazards during live work. The exhaust end of the refrigerated dryer 25 is connected to a second insulated air pipe 31.

The fifth insulating air pipe 34 is used to deliver cold air and ensure the stable delivery of cold air. The hot end pipe 383 is connected to the reversing valve 39 through the sixth insulating air pipe 35. The sixth insulating air pipe 35 is used to deliver hot air and realize the separate delivery of cold and hot air. The working end of the reversing valve 39 is connected to the inside of the insulating hopper 8 through the seventh insulating air pipe 36 to send the regulated airflow into the insulating hopper 8 to realize temperature control. The exhaust end of the reversing valve 39 is connected to the silencer 40 through the eighth insulating air pipe 37 to deliver the exhaust airflow to the silencer 40 and reduce emission noise.

[0035] Please see the appendix Figure 2 The independent hydraulic drive assembly also includes a hydraulic oil tank 19, which stores hydraulic oil and provides an oil source for the second hydraulic pump 18 and the first hydraulic pump 17. The outlet of the hydraulic oil tank 19 is connected to a fifth hydraulic oil pipe 28, which delivers hydraulic oil to the second hydraulic pump 18. The other end of the fifth hydraulic oil pipe 28 is connected to the suction end of the second hydraulic pump 18 to ensure stable oil intake. The output end of the second hydraulic pump 18 is connected to a sixth hydraulic oil pipe 29, which delivers pressurized high-pressure hydraulic oil.

The return end of the hydraulic motor 23 is connected to a fourth hydraulic oil pipe 27, which delivers low-pressure hydraulic oil after work back to the hydraulic oil tank 19. The other end of the fourth hydraulic oil pipe 27 is reconnected to the hydraulic oil tank 19, forming a complete independent hydraulic circuit to ensure the recycling of hydraulic oil and maintain stable circuit pressure.

[0036] Please see the appendix Figure 1 The aerial work platform includes a truck cab 1, which provides the mobile carrier and power source for the entire equipment. A truck bed 2 is connected to the rear of the truck cab 1. The truck bed 2 is used to install equipment such as gas preparation and purification components, providing installation space. The gas preparation and purification components are fixedly connected inside the truck bed 2. The fixed installation can ensure the stable operation of the equipment and avoid shaking during aerial work. A base 3 is installed on the truck bed 2. The base 3 provides fixed support for the boom structure and ensures the stable operation of the boom. A lower arm 4 is movably hinged above the base 3. The lower arm 4 is used to drive the upper arm 5 and the insulated arm 6 to lift and lower, realizing the height adjustment of the insulated bucket 8.

[0037] The lower arm 4 is movably connected to the upper arm 5 at the end furthest from the base 3. The upper arm 5 is used to extend the working radius and expand the working range. The other end of the upper arm 5 is connected to an insulating arm 6.

The pipeline is laid inside to avoid pipeline wear, while ensuring insulation performance and preventing external interference.

[0038] Please see the appendix Figure 1 -Appendix Figure 2 The vehicle's front end 1 houses an engine and a transmission 15, which provide power to the entire device and ensure the normal operation of all components. A power take-off (PTO) 16 is connected to the drive end of the engine and transmission 15. The PTO 16 distributes engine power to the first hydraulic pump 17 and the second hydraulic pump 18, achieving a reasonable power distribution. The power distribution end of the PTO 16 also connects to both the second hydraulic pump 18 and the first hydraulic pump 17, ensuring that the two hydraulic pumps receive power synchronously without interference. The discharge end of the first hydraulic pump 17 is connected to a first hydraulic oil pipe 20, which transports the high-pressure hydraulic oil discharged by the first hydraulic pump 17. The output end of the first hydraulic oil pipe 20 is connected to a second hydraulic oil pipe 21, which diverts the high-pressure hydraulic oil to provide power to different actuators. The output end of the second hydraulic oil pipe 21 is connected to a third hydraulic oil pipe 22. The first hydraulic oil pipe 20, the second hydraulic oil pipe 21, and the third hydraulic oil pipe 22 together constitute the main oil supply circuit for driving the aerial work platform, providing stable hydraulic power for the main operating actions.

[0039] The branch end of the main oil supply circuit is connected to the ninth hydraulic oil pipe 43. The ninth hydraulic oil pipe 43 is used to divert the main oil supply circuit and provide hydraulic power to the operating valve group 10. The oil supply end of the ninth hydraulic oil pipe 43 is connected to the operating valve group 10. The operating valve group 10 is used to control the oil inlet and reversing of each cylinder and motor to realize various actions of the boom. The first working oil port of the operating valve group 10 is connected to the lower boom lifting cylinder 12 through the eighth hydraulic oil pipe 42 to control the extension and retraction of the lower boom lifting cylinder 12 to realize the lifting and lowering of the lower boom 4. The second working oil port of the operating valve group 10 is connected to the upper boom lifting cylinder 13 through the seventh hydraulic oil pipe 41 to control the extension and retraction of the upper boom lifting cylinder 13 to realize the undulation of the upper boom 5. The operating valve group 10 is covered with an operating valve protective cover 9. The operating valve protective cover 9 is used to protect the operating valve group 10, prevent dust and debris from entering and affecting its operating accuracy, and also play a certain role in insulation protection.

[0040] Working principle: The temperature control device inside the live-line working insulated bucket is installed on a standard live-line working vehicle chassis consisting of a truck cab 1 and a truck bed 2. The chassis upper structure is based on the base 3 that supports the boom and the slewing center 11 that ensures rotational connection.

[0041] First, the power source of the entire equipment is the vehicle's engine and transmission 15. The power is output through the power take-off unit 16 and distributed to a dual hydraulic pump. The first hydraulic pump 17 is responsible for driving the vehicle's original high-altitude operation function. The first hydraulic pump 17 draws hydraulic oil from the shared hydraulic oil tank 19 and delivers high-pressure oil to the upper arm lifting cylinder 13 through the seventh hydraulic oil pipe 41 to provide undulating power. It also delivers high-pressure oil to the lower arm lifting cylinder 12 through the eighth hydraulic oil pipe 42 to provide lifting power, and provides hydraulic power to the operating valve group 10 through the ninth hydraulic oil pipe 43. The operator controls the oil intake and reversing of each cylinder and motor through the operating valve group 10, thereby realizing the lifting, extension, and rotation of the lower arm 4, upper arm 5, insulated arm 6, small crank arm 7, and telescopic mechanism 14. Finally, the insulated bucket 8 carrying the personnel is positioned and delivered to the work point. The insulated bucket 8 is protected by the operating valve protective cover 9.

[0042] Meanwhile, the second hydraulic pump 18 forms an independent hydraulic circuit. The second hydraulic pump 18 draws hydraulic oil from the hydraulic oil tank 19 through the fifth hydraulic oil pipe 28, and delivers the pressurized high-pressure hydraulic oil through the sixth hydraulic oil pipe 29 to drive the hydraulic motor 23 installed in the truck bed 2. The low-pressure hydraulic oil after work is delivered back to the hydraulic oil tank 19 through the fourth hydraulic oil pipe 27. Through the parallel design of the two pumps, it is ensured that the operation of the temperature control component and the operation of the vehicle boom do not interfere with each other, thus ensuring the safety and stability of the operation.

[0043] When the independent hydraulic circuit is activated, the hydraulic motor 23 converts hydraulic power into mechanical power, directly driving the air compressor 24 to compress ambient air into high-pressure gas. To ensure the comfort and safety of the gas delivered to the insulated hopper 8, the compressed high-temperature and high-humidity gas needs to be purified. The high-pressure gas first enters the refrigerated dryer 25 through the first insulated gas pipe 30 for cooling and dehumidification, and then enters the gas storage filter 26 through the second insulated gas pipe 31 for pressure stabilization and deep purification to achieve medical-grade cleanliness standards.

[0044] The purified high-pressure gas begins its long-distance insulated transport journey via the third insulated gas pipe 32. The high-pressure gas safely passes through the air passage slip ring inside the slewing center 11, then along the fourth insulated gas pipe 33 laid inside the boom, finally reaching the vortex pipe 38, reversing valve 39, and muffler 40 located below the insulated bucket 8. The entire transport process uses insulated piping, ensuring that the temperature control components do not affect the overall insulation performance of the vehicle.

[0045] In the final temperature control stage, high-pressure gas enters the vortex chamber 385 inside the vortex tube 38 through the inlet 381. Within the vortex chamber 385, it rotates at high speed and undergoes physical separation, forming a hot airflow in the outer ring and a cold airflow in the central region. The hot airflow flows along the hot end pipe 383, and its flow rate and temperature can be adjusted by the control valve 384. The cold airflow is discharged from the cold end pipe 382. The cold airflow separated from the vortex tube 38 is delivered to the reversing valve 39 through the fifth insulating gas pipe 34, and the separated hot airflow is delivered to the reversing valve 39 through the sixth insulating gas pipe 35.

[0046] Operators can operate the reversing valve 39 according to seasonal needs. In summer, cool air is directed through the seventh insulating pipe 36 into the insulating hopper 8 for cooling, while waste hot air is discharged through the eighth insulating pipe 37 into the muffler 40 for noise reduction before being released. In winter, the operation is reversed: hot air is introduced into the insulating hopper 8 through the seventh insulating pipe 36 for heating, while waste cold air is discharged through the eighth insulating pipe 37 into the muffler 40. Through the temperature control components, a comfortable and safe working environment is created for personnel performing live-line work at heights without altering the original vehicle's basic functions and safety performance.
