[0025] Example 1

[0026] Please see Figures 1-6 The diagram shows a multi-functional airport maintenance equipment, including a tractor 1, and a front fixed seat 2 and a rear fixed seat 3 disposed at the front and rear ends of the tractor 1.

[0027] The front fixed base 2 is detachably connected to a six-in-one loading bucket 101, a snowplow 102, and forks 103;

[0028] The rear mounting base 3 is detachably connected to the digging device 110, the lawnmower 111, the hydraulic breaker 113, and the sprayer 114;

[0029] The front fixed seat 2 consists of a mounting assembly 201, a boom assembly 202, and a connecting frame assembly 203. The boom assembly 202 is connected to the connecting frame assembly 203 and the mounting assembly 201 via hydraulic cylinders and connecting rods. The boom assembly 202 controls the lifting operation via hydraulic cylinders and controls the mounting assembly 201 to complete operations such as changing work attachments and transporting materials. The mounting assembly 201 is connected to the six-in-one loading bucket 101, the snowplow 102, and the forks 103 via multiple pins 4.

[0030] The rear fixed seat 3 consists of a connecting seat 301, a connecting frame seat 302 and a support frame 303 located on the side of the connecting seat 301 away from the tractor 1. The connecting frame seat 302 and the support frame 303 are respectively connected to the excavating device 110, the lawn mower 111, the hydraulic breaker 113 and the sprayer 114 through one or more pins 4.

[0031] The pin component 4 consists of a pin rod 401 and a pin baffle 402 disposed at one end of the pin rod 401. The pin rod 401 is provided with an anti-disengagement component for preventing disengagement during the pin connection process of each device.

[0032] It should be noted that the cooperation of the front fixed seat 2, the rear fixed seat 3 and the pin 4 realizes the multi-functionality of the airport maintenance equipment. It has good safety, adaptability and reliability, and is easy to maintain and low in cost. It can not only adapt to a variety of complex working conditions, but also improve the efficiency of carrying and quickly changing various hydraulic attachments to complete a variety of engineering operations, thereby meeting the needs of less manpower, cost economy and multi-functional development.

[0033] It is worth noting that Tractor 1 serves as both a platform for airport maintenance operations and a power source for various tasks, requiring it to have heavy-duty axle loads, strong power, high torque at low speeds, and a panoramic cab. As this is existing technology, it will not be elaborated on further here.

[0034] The 101 six-in-one loading bucket is a loading bucket equipped with bucket teeth. It is a multi-functional machine that integrates six functions: loading, bulldozing, leveling, grabbing, lifting, and spreading sand and gravel. As it is existing technology, it will not be described in detail here.

[0035] The snowplow 102 is used for snow removal on airport runways. It is installed and fixed at the front of the tractor 1. The working power is provided by the front output of the engine of the tractor 1 to complete the snow removal operation. The lifting and lowering of the snow throwing module is achieved by a four-bar linkage driven by a hydraulic system. As this is existing technology, it will not be described in detail here.

[0036] The fork 103 is mainly composed of a fork plate, a fork carriage, and a joint shaft. The fork 103 is controlled by a hydraulic cylinder to complete the forklifting and transporting of goods and materials. As this is existing technology, it will not be described in detail here.

[0037] The excavation device 110 is similar in structure to existing excavators, and as it is prior art, it will not be described in detail here.

[0038] The lawnmower 111 is attached to the rear end of the chassis of the tractor 1. The cutting system is driven to rotate at high speed through the power output of the chassis of the tractor 1, so that the blades on the cutting system rotate synchronously to generate a certain cutting force to cut the weeds and achieve the function of mowing grass. As this is existing technology, it will not be described in detail here.

[0039] The hydraulic breaker 113 is mainly composed of a chisel, guide sleeve, valve core, valve box, piston, and front hydraulic cylinder, etc. As it is existing technology, it will not be described in detail here.

[0040] The sprayer 114 uses the tractor 1 as a power source and the traction chassis as a carrier to realize the traction drive and steering of the sprayer 114 by the tractor 1. The power of the PTO output shaft of the power chassis is transmitted to the liquid pump through the transmission shaft. The operation of the liquid pump draws the liquid from the tank, and after being pressurized by the pump, it is distributed to the nozzles on each section of the spray bar through the pressure regulating valve of the spray bar assembly. After atomization by the nozzles, it is sprayed out, thereby realizing the driving of the liquid pump and the spraying operation. As this is existing technology, it will not be described in detail here.

[0041] Working principle: When in use, this multi-functional maintenance equipment for the airport can quickly connect and replace the six-in-one loading bucket 101, snowplow 102 and forklift 103 by using the cooperation of the front fixed seat 2 and the pin 4, thereby realizing the functions of loading, bulldozing, grabbing, lifting, forklift loading and unloading, paving and snow removal. At the same time, it can also quickly connect and replace the excavating device 110, lawn mower 111, hydraulic breaker 113 and sprayer 114 by using the cooperation of the rear fixed seat 3 and the pin 4, thereby realizing the functions of excavation, breaking, mowing, snow removal and pesticide spraying.

[0042] Therefore, through the combined action of the front fixed seat 2, the rear fixed seat 3 and the pin 4, the airport maintenance equipment achieves multi-functionality, with good safety, adaptability and reliability, and convenient maintenance and low cost. It can not only adapt to a variety of complex working conditions, but also improve the efficiency of carrying and quickly replacing various hydraulic attachments to complete a variety of engineering operations, thereby meeting the needs of less manpower, cost economy and multi-functional development.

[0043] Example 2

[0044] Please see Figure 5 and Figure 6This embodiment further illustrates Example 1. The anti-detachment component shown in the figure includes a mounting cavity 501 opened in the pin rod 401. The inner wall of the mounting cavity 501 is provided with a plurality of through holes 502. Each through hole 502 is connected to an anti-detachment plate 503 through a guide component. The mounting cavity 501 is provided with a drive component for driving each anti-detachment plate 503.

[0045] It should be noted that the anti-detachment component, in conjunction with the guide component, drive component, and telescopic component, provides a blocking and limiting effect on the insertion of the pin 401, reducing the risk of the pin 401 falling off due to vibration or swing during use, thereby improving the connection stability of the pin 401 to various devices.

[0046] Please see Figure 5 and Figure 6 The guide assembly shown in the figure includes guide grooves 601 formed on two opposite side walls of the anti-detachment plate 503. Guide plates 602 are slidably connected to the two guide grooves 601. The ends of the two guide plates 602 that are far apart from each other are connected to the inner wall of the through hole 502.

[0047] It should be noted here that the guide components are designed to guide and limit the movement of each anti-detachment plate 503.

[0048] Please see Figure 5 and Figure 6 The drive assembly shown in the figure includes a drive plate 701 slidably connected to the mounting cavity 501. Multiple rotating plates 702 are hinged to the side of the drive plate 701 near each anti-detachment plate 503. The end of each rotating plate 702 away from the drive plate 701 is respectively hinged to each anti-detachment plate 503. A T-shaped rod 703 is slidably connected to the end of the pin rod 401 away from the pin baffle 402. One end of the T-shaped rod 703 is connected to the drive plate 701. The mounting cavity 501 is provided with a telescopic assembly for extending and retracting the drive plate 701.

[0049] It should be noted here that the drive components are configured to move each anti-detachment plate 503 away from or towards each other.

[0050] Please see Figure 5 and Figure 6 The T-shaped rod 703 in the figure is rotatably connected to a T-shaped threaded rod 704 on its side wall. The pin rod 401 has a threaded hole 705 at one end near the T-shaped threaded rod 704. The threaded hole 705 is matched with the T-shaped threaded rod 704.

[0051] It should be noted here that the threaded connection between the T-shaped threaded rod 704 and the threaded hole 705 is used to push and lock the drive plate 701, thereby causing each anti-detachment plate 503 to retract into the mounting cavity 501, thus reducing the interference of the pin rod 401 during the insertion and removal process.

[0052] Please see Figure 5 and Figure 6 The telescopic assembly shown in the figure includes a telescopic tube 801 fixedly connected to the bottom wall of the mounting cavity 501, a telescopic rod 802 slidably connected to the telescopic tube 801, one end of the telescopic rod 802 away from the pin baffle 402 being connected to the drive plate 701, and a spring 803 sleeved on the side wall of the telescopic tube 801, with both ends of the spring 803 being connected to the bottom wall of the mounting cavity 501 and the drive plate 701 respectively.

[0053] It should be noted here that the telescopic component is used to guide and reset the movement of the drive board 701.

[0054] Working principle: After the pin 401 is inserted into the connecting hole, the T-shaped threaded rod 704 is rotated to separate the T-shaped threaded rod 704 from the threaded hole 705, thereby releasing the locking limit on the T-shaped rod 703. At this time, under the elastic action of the telescopic component, the drive plate 701 will be pushed to move in the mounting cavity 501.

[0055] As the drive plate 701 moves within the mounting cavity 501, it will push each rotating plate 702 to rotate. Under the pushing force of each rotating plate 702 and the guiding action of the guide component, each anti-detachment plate 503 will be pushed away from each other, thereby causing each anti-detachment plate 503 to move out of the mounting cavity 501. This provides a blocking and limiting effect for the insertion of the pin 401, reducing the risk of the pin 401 falling off due to vibration or swing during use, and thus improving the connection stability of the pin 401 to each device.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
