Description

Technical Field

[0001] This application relates to the field of secondary jacking technology for large-scale road maintenance machinery, and in particular to a secondary jacking device and machinery for mechanical equipment. Background Technology

[0002] Large-scale track maintenance machinery plays a crucial role in railway maintenance. For example... Figure 1 As shown, large road maintenance machinery driven by internal combustion engines usually requires a two-stage roof structure 5 above the power compartment to ensure heat dissipation and ventilation of the power unit, while also providing a certain degree of protection to prevent a large amount of rainwater from entering the interior of the power compartment.

[0003] Currently, the secondary roof structure 5 designed for large road maintenance machinery is directly welded to the roof 1 of the machinery via support columns 4, with a fixed height. Hot air in the power compartment can only be exhausted from both sides. The existing secondary roof structure 5 has the following disadvantages:

[0004] Defect 1: The height of the secondary roof structure is fixed and cannot be adjusted later. If the height is too high, rainwater intrusion will be obvious, while if the height is too low, the exhaust resistance in the power room will increase, and the power unit will generate high temperature during operation.

[0005] Defect 2: For some vehicle models where the power unit draws air from the side wall of the vehicle body, when the vehicle is operating at low speed or in a fixed position within a confined space, the hot air exhausted between the secondary roof structure 5 and the roof 1 will be drawn back into the power compartment through the air intake on the side wall of the vehicle body, causing high temperatures in the power compartment and ultimately leading to high temperatures in the power unit. Excessively high operating temperatures can cause torque limitation in the power unit and even safety accidents, affecting driving safety. Utility Model Content

[0045] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments.

[0049] See Figures 2 to 5 As shown, the first aspect of this application provides a secondary top device for mechanical equipment, including: a lifting assembly 2 and a shielding frame 3. The lifting assembly 2 is used to be installed on the top canopy 1 of the mechanical equipment. The shielding frame 3 includes a first frame 31 and a louver assembly 32. The first frame 31 and the top canopy 1 of the mechanical equipment are spaced apart. The first frame 31 is connected to the lifting assembly 2. The first frame 31 has a first frame exhaust port 311, which is connected to the top canopy exhaust port 11 on the top canopy 1. The louver assembly 32 is installed on the first frame 31 to close or open the first frame exhaust port 311. The lifting assembly 2 can drive the shielding frame 3 to move up and down to adjust the distance between the shielding frame 3 and the top canopy exhaust port 11.

[0050] The secondary top device for mechanical equipment described in this application is adaptable to various types of mechanical equipment. It features a lifting assembly 2, allowing for height adjustment based on different vehicle models and operating conditions. The secondary top device's shielding frame 3 is equipped with a first frame exhaust port 311, which increases exhaust efficiency and prevents the secondary top device from discharging hot air to the sides. This prevents hot air from being drawn into the power compartment through the side wall air inlets, causing high temperatures in the power compartment and ultimately leading to high temperatures in the power unit. In rainy weather, the first frame exhaust port 311 can be closed by a louver assembly 32 to prevent rainwater intrusion. The louver assembly 32 can adjust the opening of the first frame exhaust port 311, controlling its opening and closing according to the power unit load and vehicle operating environment conditions, thereby adjusting the direction of hot air exhaust from the power unit.

[0051] In some possible implementations, the lifting assembly 2 includes multiple lifting components 21, each of which is arranged sequentially at intervals along the edge of the ceiling exhaust port 11. Each lifting component 21 is connected to the ceiling 1 of the mechanical equipment, and the end of each lifting component 21 facing away from the ceiling 1 is connected to the first frame 31. The lifting components 21 can move up and down along the height direction of the mechanical equipment, adjusting the distance between the shielding frame 3 and the ceiling exhaust port 11 to adapt to mechanical equipment of different sizes, specifications, and structures. Each lifting component 21 is supported at different positions on the first frame 31, and each lifting component 21 can move up and down synchronously to smoothly support or lower the shielding frame 3. The lifting component 21 may include a base 211 and a telescopic rod 212, with the base 211 connected to the ceiling 1 and the telescopic rod 212 connected to the first frame 31.

[0052] In some possible implementations, the first frame 31 includes a skeleton 312 and an air collecting hood 313, the lifting assembly 2 is connected to the skeleton 312, the air collecting hood 313 is connected to the skeleton 312, the air collecting hood 313 encloses to form the exhaust port 311 of the first frame, and the louver assembly 32 is disposed on the skeleton 312.

[0053] The frame 312 is preferably made of rectangular tubes, U-shaped channels and other structures spliced ​​together, and the skin is preferably made of sheet metal spliced ​​together, with the sheet metal fixed to the frame 312.

[0054] See some possible implementations. Figure 3As shown, the air collection hood 313 includes multiple inclined guide plates 3131, each of which is arranged sequentially along the circumference of the first frame exhaust port 311. Adjacent inclined guide plates 3131 are connected, and each inclined guide plate 3131 extends inclinedly towards the roof 1 and away from the first frame exhaust port 311. Each inclined guide plate 3131 forms a space that is small at the top and large at the bottom, which can collect airflow. The hot air discharged from the roof exhaust port 11 on the roof 1 can be smoothly collected and discharged upward from the first frame exhaust port 311 at the top, preventing the secondary roof device from discharging hot air to both sides, causing hot air to be drawn into the power compartment by the air inlet on the side wall of the vehicle body, resulting in high temperature in the power compartment and ultimately leading to high temperature of the power unit.

[0055] See some possible implementations. Figure 2 and Figure 3 As shown, the first frame 31 divides the first frame exhaust port 311 into multiple sub-vents. The louver assembly 32 includes multiple louver modules 321. Each louver module 321 is disposed on the first frame 31. Each louver module 321 covers the corresponding sub-vent. Each louver module 321 is used to close or open the corresponding sub-vent.

[0056] See some possible implementations. Figure 4 As shown, the louver module 321 includes a drive mechanism, a second frame 3213, and multiple blades 3214. The second frame 3213 is mounted on the first frame 31, and each blade 3214 is movably disposed on the second frame 3213. The drive mechanism is disposed on the second frame 3213, and the drive mechanism and each blade 3214 are connected in a transmission relationship to drive each blade 3214 to rotate, so as to close or open the corresponding sub-vent.

[0057] The second frame 3213 and the blades 3214 constitute the louver structure. The drive mechanism can control the opening degree of the louvers according to the load rate of the power unit, the operating speed, the weather, and the environmental conditions of the vehicle's operating location. When the louvers are fully open, each blade 3214 is vertically downward, which can exhaust hot air upward and prevent hot air from being exhausted to the sides.

[0058] Each louver module 321 has a corresponding drive mechanism, and each louver module 321 constitutes an independent louver structure. Each louver module 321 can be independently controlled to open and close, thereby enabling the opening of some louver modules 321 and the simultaneous opening and closing of all louver modules 321.

[0059] See some possible implementations. Figure 4As shown, the second frame 3213 includes an outer frame 32131 and a guide rail 32132 disposed in the middle of the outer frame 32131. The guide rail 32132 forms two openings in the outer frame 32131. A plurality of blades 3214 are sequentially disposed in each opening. The driving mechanism includes a second telescopic component 3211 and two sliding components 3212. The two sliding components 3212 are disposed on both sides of the guide rail 32132 and are slidably connected to the guide rail 32132. Each sliding component 3212 is drivenly connected to each blade 3214 on the same side of the guide rail 32132. The second telescopic component 3211 is disposed on the guide rail 32132 and is drivenly connected to the two sliding components 3212 to drive each blade 3214 to rotate synchronously.

[0060] The second telescopic component 3211 can employ a pneumatic, hydraulic, or electric telescopic control structure. Each blade 3214 has a rotating shaft at both ends along its length. One shaft is connected to the outer frame 32131, and the other shaft is connected to the guide rail 32132. A guide groove can be provided on the guide rail 32132, extending along its length. A sliding member 3212 is slidably mounted on the guide groove, which guides and limits the sliding member 3212, preventing it from detaching from the guide rail 32132.

[0061] The sliding member 3212 can drive the blades 3214 on the same side of the guide rail 32132 to rotate synchronously through a linkage structure, rack and pinion transmission mechanism or other transmission methods.

[0062] The blade 3214 is rotatably connected to the guide rail 32132 via a rotating shaft. A gear is provided on the rotating shaft. The sliding member 3212 has a rack portion, and the rack portion meshes with the gear.

[0063] A shaft hole can be provided on the guide rail 32132, which connects to the guide groove. The rotating shaft is rotatably mounted in the shaft hole, and the gear on the rotating shaft is exposed in the guide groove. When the sliding member 3212 is placed in the guide groove, the rack portion of the sliding member 3212 meshes with the gears on the rotating shafts of each blade 3214. By driving the sliding member 3212 to move through the second telescopic member 3211, each blade 3214 can be driven to rotate synchronously.

[0064] The end of the second telescopic component 3211 is provided with a transmission component 3215. The transmission component 3215 has two transmission frames, which extend to both sides of the guide rail 32132 respectively, so as to be connected to the sliding members 3212 on both sides of the guide rail 32132 respectively.

[0065] The transmission component 3215 may include two transmission frames, each connected to a corresponding sliding member 3212. The two transmission frames are connected by a shaft, which is perpendicular to the guide rail 32132. The telescopic end of the second telescopic component 3211 is connected to the shaft to simultaneously drive the two transmission frames to move. The transmission frames may have a roughly herringbone structure.

[0066] In some possible implementations, when the blades 3214 are rotated to be in the same plane, the blades 3214 are in sealed contact with each other, and the blades 3214 and the second frame 3213 are in sealed contact, thereby preventing rainwater from entering the roof vent 11 on the roof 1. For example, each blade 3214 is provided with a sealing strip along its peripheral edge, and when the blades 3214 are in a horizontal state, the sealing strips of adjacent blades 3214 are in sealed contact, and the sealing strips on the end blades 3214 are in sealed contact with the second frame 3213.

[0067] This application also provides a mechanical device, including: a vehicle body and the above-mentioned secondary roof device. The vehicle body has a roof 1, on which a roof exhaust port 11 is provided. The lifting assembly 2 of the secondary roof device is disposed on the roof 1 of the mechanical device. The first frame exhaust port 311 on the shielding frame 3 of the secondary roof device is connected to the roof exhaust port 11 on the roof 1.

[0068] The lifting component 2 of the secondary top device can be steplessly adjusted between the lowest and highest heights. The adjustment height is calculated and confirmed based on the load rate of the power unit and the working speed of the mechanical equipment, so that large road maintenance machinery can better adjust the top height according to work needs in different operating scenarios.
