Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery vehicles, and in particular to an insulating aerial work vehicle with an insulating arm having a built-in cold and warm pipeline transportation system. Background Art

[0002] With the rapid development of the national economy, people have higher and higher requirements for power supply reliability, and have new upgrade needs for insulated aerial work vehicles that are used to ensure power emergency repair operations. It is hoped that new equipment and technology can be developed to effectively solve the problem of heatstroke or coldness among people working in insulated buckets during emergency repairs in summer and winter.

[0003] The existing cooling and heating technology for the working bucket of an insulated aerial work vehicle is to install bulk air conditioners and hydraulic motors on the working bucket to drive the air conditioners. The air conditioners and hydraulic motors are heavy. After being installed on the working bucket, they will greatly reduce the key working bucket load size and operating range parameters of the aerial work vehicle, and therefore have no practical use value.

[0004] Assuming that the air conditioner is placed on a turntable, the cold and warm pipes at the air outlet of the air conditioner need to pass through the insulating arm before delivering the cold and warm gas to the working bucket. However, the cold and warm pipes are susceptible to condensation due to the temperature difference of the external environment when delivering air, which causes the insulating arm to get damp. At present, the pipes at the air outlet of the air conditioner are insulated by wrapping the outside with aluminum foil or sponge material. The cold and warm gas in the pipe will transfer the temperature to the aluminum foil or sponge through thermal radiation. After combining with the moisture in the air, it will still produce condensation on the surface of the pipe and the surface of the aluminum foil or sponge insulation layer. In addition, the conductivity of the aluminum foil will directly destroy the insulation performance of the arm.

[0005] However, the insulating arms of aerial work vehicles are generally used as the main insulation. The insulation performance will be significantly reduced after being exposed to moisture, which will directly affect the key indicators of the insulation performance of the insulated aerial work vehicles. It is necessary to develop new equipment and technologies to achieve breakthroughs. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the application is further elaborated in detail below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments involved in the present invention. All non-innovative embodiments of other researchers in the field on this embodiment belong to the protection scope of the present invention. At the same time, for the step numbering in the embodiment of the present invention, it is only set for the convenience of explanation, and the order between the steps is not limited in any way. The execution order of each step in the embodiment can be adaptively adjusted according to the understanding of those skilled in the art.

[0030] In one embodiment of the present invention, an insulating aerial work vehicle having an insulating arm and a built-in cold and warm pipe delivery system, such as Figure 1 As shown, it includes: a chassis 1, a frame 2, a turntable 3, an insulating arm 4, an air conditioning system assembly and a working bucket 6 and other components, and the above main components are assembled in sequence to form an insulating aerial work vehicle.

[0031] Furthermore, the air conditioning system assembly includes: a cooling and heating air conditioner 5-1, a controller 5-2, a cooling and heating pipeline delivery system 5-3 and an air exhaust vent 5-4 and other components.

[0032] The air conditioner 5-1 and the controller 5-2 are arranged at the turntable. The cold and warm air output by the air conditioner 5-1 passes through the cold and warm pipe conveying system 5-3, passes through the inside of the insulating arm 4, and is then conveyed to the air exhaust outlet 5-4 arranged at the working bucket, so as to realize air conditioning and ventilation at the working bucket 6.

[0033] The cold and warm pipeline delivery system 5-3 includes: a first dryer 7, an air pipe assembly 8, a humidity sensor, an electromagnetic air valve, a connecting air pipe 11, a plug 12 and a pressure switch and other components.

[0034] Furthermore, if Figure 2 and Figure 3 As shown, the main structure of the air pipe assembly 8 is composed of main components such as the outer layer tube 8-1, the inner layer tube 8-2 and the inner rib 8-3.

[0035] As a preferred solution, in this embodiment, the main structure of the air pipe assembly 8 is made of a silicone material with good insulation and flexibility.

[0036] Furthermore, the main structure of the above-mentioned air pipe assembly 8 adopts a double-core structure of an outer tube 8-1 and an inner tube 8-2, so that the inner sides of the outer tube 8-1 and the inner tube 8-2 do not communicate with each other and do not interfere with each other, and an inner rib 8-3 is set between the outer tube 8-1 and the inner tube 8-2.

[0037] The double-core structure of the outer tube 8-1 and the inner tube 8-2 is supported by the inner rib 8-3, so there will be no blocking phenomenon when twisting.

[0038] Furthermore, an air inlet hole 8-1-1 is provided on the outer layer tube 8-1 at the lower end of the air pipe assembly 8, and the air outlet end of the branch tube 8-4 passes through the air inlet hole 8-1-1 and is further connected to the interior of the outer layer tube 8-1.

[0039] Furthermore, the electromagnetic valve is set as a two-position three-way device, and its C port is set as an exhaust port connected to the atmosphere. The air outlet of the air conditioner 5-1 is connected to the first dryer 7, the humidity sensor, the pressure switch and the A port of the electromagnetic valve in sequence through the connecting air pipe 11, and then connected to the inner layer pipe 8-2 at the lower end of the air pipe assembly 8 through the B port of the electromagnetic valve, and connected to the air exhaust port 5-4 set at the working bucket through the inner layer pipe 8-2.

[0040] As a preferred complete solution:

[0041] The heating pipeline conveying system 5-3 also includes: a second dryer and a blower. The lower end of the air pipe assembly 8 is provided with a plug 12, which is installed between the outer layer pipe 8-1 and the inner layer pipe 8-2, so that the inner side 8-1 of the outer layer pipe at the lower end of the air pipe assembly 8 is sealed by the plug 12 and is not ventilated to the outside.

[0042] The air outlet of the cold blower is connected to the air inlet of the second dryer, and then connected to the outer tube 8-1 at the lower end of the air pipe assembly 8 through the air outlet of the second dryer, and the outer tube 8-1 at the working bucket end of the air pipe assembly 8 is connected to the atmosphere, so that there is no temperature difference between the natural wind at the air outlet of the blower and the atmosphere, and the moisture and impurities are removed after drying, so that the gas entering the outer tube 8-1 itself will not condense water, and the temperature of the outer tube 8-1 after being affected by the incoming gas is also consistent with the atmosphere, so that there will be no condensation on the outer wall of the outer tube 8-1, and the insulation performance will not be reduced after the inside of the insulating arm is wetted, thereby ensuring that the air pipe assembly 8 enters the inside of the insulating arm frame 4 and extends to the working bucket.

[0043] When in use, the air conditioner 5 - 1 is started by the controller 5 - 2 , and the gas output by the air conditioner 5 - 1 passes through the first dryer 7 to remove moisture and impurities.

[0044] When the dried gas does not reach the humidity set by the humidity sensor, or the wind speed does not reach the setting value of the pressure switch, the controller 5-2 executes the following logic program: on the one hand, the opening of the electromagnetic valve is switched to port C to discharge the invalid gas into the atmosphere. On the other hand, the blower is automatically shut down to achieve energy-saving control under invalid working conditions.

[0045] When the dried gas reaches the humidity set by the humidity sensor and the wind speed reaches the setting value of the pressure switch, the controller 5-2 executes the following logic program: On the one hand, the B port of the electromagnetic air valve is opened, so that the cold and warm air output by the cold and warm air conditioner 5-1 is transported from the inner layer pipe 8-2 to the exhaust air outlet 5-4 at the working bucket 6, so as to achieve the cold and warm ventilation effect at the working bucket 6. On the other hand, the blower is automatically started to operate, and the above-mentioned anti-condensation control is performed on the outer layer pipe 8-1 while outputting the cold and warm air.

[0046] As a preferred complete solution 2:

[0047] The cold and warm pipe delivery system 5-3 also includes: a vacuum pump, a vacuum pressure sensor and a vacuum tank gas. The air inlet of the vacuum pump is connected to the air outlet of the vacuum tank, and then connected to the inner side of the outer layer tube 8-1 through the air inlet of the vacuum tank and the branch pipe 8-4 in sequence.

[0048] Both upper and lower ends of the air pipe assembly 8 are provided with plugs 12, which are installed between the outer tube 8-1 and the inner tube 8-2. After the outlets of the inner side 8-1 of the outer tube at both ends of the air pipe assembly 8 are sealed by the plugs 12, the gap between the outer tube 8-1 and the inner tube 8-2 is connected to the vacuum air tank 18 to form a closed space.

[0049] After starting the vacuum pump to extract the gas in the above-mentioned enclosed space, the gap between the outer tube 8-1 and the inner tube 8-2 becomes a vacuum layer, which has the physical effect of insulation and heat insulation, so that the air pipe assembly 8 will no longer have condensation effect when transporting cold or hot gases, thereby avoiding the insulation arm from getting wet.

[0050] A vacuum pressure sensor is provided on the vacuum air tank, which detects the vacuum degree of the above-mentioned enclosed space and sends a signal to the controller 5-2.

[0051] When in use, the air conditioner 5 - 1 is started, and the gas output by the air conditioner 5 - 1 passes through the first dryer 7 to remove moisture and impurities.

[0052] When the dried gas does not reach the humidity set by the humidity sensor, or the vacuum degree does not reach the vacuum pressure sensor, the controller 5-2 executes the following logic program: On the one hand, the opening of the electromagnetic valve is switched to port C to discharge the invalid gas into the atmosphere. On the other hand, the vacuum pump is automatically turned on to increase the vacuum degree of the above-mentioned enclosed space.

[0053] When the dried gas reaches the humidity set by the humidity sensor, and the vacuum degree reaches the value set by the vacuum pressure sensor, the controller 5-2 executes the following logic program: on the one hand, the vacuum pump is automatically shut down to realize energy-saving control while satisfying the above-mentioned anti-condensation control of the outer tube 8-1. On the other hand, the B port of the electromagnetic valve is automatically opened, so that the cold and warm air output by the air conditioner 5-1 is transported from the inner tube 8-2 to the exhaust air outlet 5-4 at the working bucket 6, realizing the cold and warm ventilation effect at the working bucket 6.

[0054] In particular, the above-mentioned heating and cooling air conditioner 5-1, controller 5-2, blower, first dryer, second dryer, humidity sensor, pressure switch, solenoid valve, vacuum pump, vacuum pressure sensor and vacuum air tank are all arranged at the turntable 3, and the exhaust air outlet 5-4 is arranged at the working bucket 6, which can not only realize the heating and cooling air supply to the working bucket, but also will not affect the main engine performance of the insulated aerial work vehicle.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
