[0004] The existing drive axles of electric luggage conveyor belt vehicles for airports have certain disadvantages during use. The drive axles of traditional electric luggage conveyor belt vehicles for airports adopt an internal combustion single-stage reduction form, which makes the volume of the traditional drive axle larger and the ground clearance smaller, thereby causing the volume and weight of the tractor to increase accordingly, making it impossible to use it in narrow places, reducing the vehicle's passability; secondly, the drive axles of traditional electric luggage conveyor belt vehicles for airports do not have a quick installation structure, thereby increasing the steps of maintenance and disassembly operations of the drive axles of electric luggage conveyor belt vehicles for airports; secondly, the drive axles of traditional electric luggage conveyor belt vehicles for airports do not have an auxiliary buffer structure, which cannot reduce the vibration of the drive axle when in use, bringing certain adverse effects to users. Summary of the invention

[0005] In order to overcome the problem that the traditional electric luggage conveyor belt vehicle for airports adopts an internal combustion single-stage reduction form in the driving axle, which makes the traditional driving axle larger in size and smaller in ground clearance, thus causing the tractor to increase in size and weight accordingly, making it impossible to use it in narrow places, reducing the vehicle's passability; secondly, the driving axle of the traditional electric luggage conveyor belt vehicle for airports does not have a quick installation structure, thereby increasing the steps in the maintenance and disassembly operation of the driving axle of the electric luggage conveyor belt vehicle for airports; secondly, the driving axle of the traditional electric luggage conveyor belt vehicle for airports does not have an auxiliary buffer structure, and cannot reduce the vibration of the driving axle when it is used, thereby providing a driving axle for an electric luggage conveyor belt vehicle for airports.

[0009] As a further solution of the present invention, movable support plates are movably installed on the inner sides of both ends of the splicing base, and a rotating base is movably installed on the bottom of the movable support plates. The movable support plates and the rotating base are fixed to each other by two sets of inner sleeve rods. The inner sleeve rods are movably installed on the inner surfaces of the movable support plates and the rotating base, and a spring column is fixedly installed on the inner surface of the rotating base near the lower end of the inner sleeve rod.

[0010] As a further solution of the present invention, the rotating base and the splicing base are movably connected via a rotating rod, a fastening screw cap is fixedly installed on the outer surface of one end of the rotating rod, a rolling rod is movably installed on the inner side of the upper end of the movable support plate, and the movable support plate and the rolling rod are movably connected via a rotating shaft.

[0011] As a further solution of the present invention, two groups of fixing bolts are fixedly sleeved on the inner side of the bottom of the splicing base, two groups of fastening chucks are movably installed on the inner side of the brake, and the brake and the fastening chucks are movably connected through a caliper, and a hydraulic cylinder is fixedly installed on the outer surface of the rear end of the brake.

[0013] As a further solution of the present invention, the specific operation steps of using the electric luggage conveyor belt vehicle drive axle are:

[0014] Step 1: Use the engine of the tractor to cooperate with the reducer in the box shell to drive the left and right half shafts, so that the left and right half shafts drive the driving wheels to complete the driving and traction of the whole vehicle;

[0015] Step 2: The user increases the hydraulic pressure in the hydraulic cylinder so that the hydraulic cylinder drives the caliper in the brake by hydraulic means, so that the caliper drives the two sets of fastening chucks to close, and the driving wheels of the left and right half shafts are clamped by the fastening chucks;

[0016] Step three, rotate the fastening screw cap to drive the rotating rod to loosen the rotating base and the splicing base, rotate the rotating base to separate the movable support plate from the sliding card plate, move the sliding card plate, and separate the first card sleeve and the second card sleeve.

[0017] Beneficial effects of the present invention:

[0018] 1. By setting a brake drum and using the brake drum in conjunction with a reducer in the housing, when the airport electric baggage conveyor belt vehicle driving axle needs to perform a braking operation, the user increases the hydraulic pressure in the hydraulic cylinder so that the hydraulic cylinder of the brake drum drives the caliper in the brake by hydraulic means, so that the caliper drives two sets of fastening chucks to close, and the driving wheels of the left and right axles are clamped by the fastening chucks, so that the driving wheels of the left and right axles stop rotating, thereby completing the braking operation of the driving axle. At the same time, the reducer can reduce the rotation speed of the left and right axles, and perform auxiliary braking operation on them. The brake drum is used in conjunction with the reducer to replace the traditional internal combustion single-stage reduction structure of the driving axle, thereby effectively improving the deceleration effect of the driving axle, making the structure of the driving axle more compact, so that the electric baggage conveyor belt vehicle installed with the driving axle can be suitable for narrow venues, thereby effectively improving the vehicle's passability.

[0019] 2. By providing a splicing card seat, when the user needs to disassemble and maintain the driving axle of the electric baggage conveyor for the airport, the user can rotate the fastening screw cap to drive the rotating rod, thereby loosening the rotating card seat and the splicing card seat, so that the user can rotate the rotating card seat to separate the moving support plate from the sliding card plate, and move the sliding card plate outward so that the sliding card plate separates the first card sleeve and the second card sleeve. After the first card sleeve and the second card sleeve are separated, the user can take out the left shaft sleeve and the right shaft sleeve stuck between the first card sleeve and the second card sleeve, so that the driving axle is removed from the first card sleeve and the second card sleeve. When the user needs to install the driving axle, the user can remove the left shaft sleeve and the right shaft sleeve from the first card sleeve and the second card sleeve. The shaft sleeve and the right shaft sleeve are simultaneously stuck between the first clamping sleeve and the second clamping sleeve, pushing the sliding clamping plate to close the first clamping sleeve and the second clamping sleeve, so that the first clamping sleeve and the second clamping sleeve are stuck on the outer surfaces of the left shaft sleeve and the right shaft sleeve, and at the same time, the rotating clamping seat is rotated so that the moving support plate of the rotating clamping seat cooperates with the rolling rod to be stuck at one end of the sliding clamping plate. The rolling rod can reduce the resistance when the moving support plate is inserted, making the docking of the moving support plate more convenient. At the same time, the tightening screw cap is rotated to drive the rotating rod, and the rotating clamping seat is locked by the rotating rod. The setting of the splicing clamping seat makes the drive axle of the electric baggage conveyor belt vehicle for the airport have a spliced ​​fixed structure, thereby reducing the difficulty of installing and disassembling the drive axle, making its maintenance operation more convenient.

[0020] 3. By setting the inner sleeve rod and the spring column, when the splicing card seat cooperates with the rotating card seat to complete the fixing operation of the drive axle, the inner sleeve rod and the spring column are used to form an elastic shock-absorbing structure between the rotating card seat and the movable support plate. When the movable support plate is pressed against the sliding card plate, the inner sleeve rod and the spring column can be used to make the first card sleeve and the second card sleeve perform a mobile shock-absorbing operation when the drive axle vibrates, so that the first card sleeve and the second card sleeve can cooperate with the movable support plate to reduce the vibration of the first card sleeve and the second card sleeve under the action of the sliding card plate, so that the splicing card seat has a buffer shock-absorbing structure. The inner sleeve rod and the spring column can enhance the shock-absorbing effect of the splicing card seat, thereby effectively reducing the vibration of the drive axle, so that the drive axle of the electric baggage conveyor belt vehicle for the airport has an auxiliary buffer structure, thereby effectively improving its stability.
