Description

Technical Field

[0001] The utility model belongs to the technical field of trailers, and in particular relates to a brake device for mobile equipment. Background Art

[0002] In order to reduce the number of drivers required for vehicle-mounted support equipment, a considerable portion of the support equipment used for ground support operations for aircraft at airports or hangars adopts a towed transportation method, that is, mobile equipment; the mobile equipment is equipped with a trailer, a tow bar, and a tow ring on the tow bar. The tow ring is put on a special airport trailer, and a pin is passed through the tow ring. The special airport trailer tows the mobile equipment for operation.

[0003] Towed aircraft maintenance air conditioning units are a type of aircraft ground service equipment used at airports. They cool or heat, filter, and dehumidify incoming air, then distribute it through a blower and ducts to regulate cabin air temperature during aircraft maintenance and support operations.

[0004] When the towing aircraft maintenance air conditioning unit is used at an airport or hangar, it needs to be towed back and forth within the airport or hangar according to the different parking positions of the aircraft, so as to serve the aircraft at different positions.

[0005] Currently, when mobile equipment is used at an airport, it is towed by a dedicated airport trailer. During the towing process, the mobile equipment may easily crash into an aircraft or other objects without control. Utility Model Content

[0022] like Figure 1 As shown, the utility model provides a braking device for a mobile device, including a trailer 1, an air-conditioning unit 2 placed on the trailer 1, a front wheel 3 and a rear wheel 4 are respectively provided at the bottom of the trailer 1, and a tow bar 5 is connected to the front wheel 3 through a brake mechanism 6.

[0023] In order to prevent the trailer 1 from uncontrolled collision with other equipment and facilities, a brake mechanism 6 is designed so that the trailer 1 can brake in time to avoid collision.

[0024] Please focus on Figure 2 The front wheels 3 are movably mounted on the bottom of the trailer 1 via a steering mechanism 7, making it easy for the operator to steer the trailer 1. When the operator turns the trailer 1 in the hangar, the operator controls the steering of the trailer 1 by operating the tow bar 5. The steering angle can be freely rotated to control the air conditioning unit 2 to avoid the aircraft.

[0025] Please focus on Figure 3 A towing ring 8 is provided at the top of the towing rod 5. The airport-specific trailer can tow the equipment and turn normally by connecting the towing ring 8.

[0026] Please focus on Figure 3-5 The brake mechanism 6 includes a pan head screw 9 provided at the bottom of the tow bar 5, and a guide hole provided on the tow bar 5, a lock hook 10 passing through the guide hole and movably installed on the tow bar 5, a mounting plate 13 installed on the connecting rod of the front wheel 3, and a hook hole provided on the mounting plate 13. At the same time, the brake lever 12 passes through a through hole provided on the side of the mounting plate 13, and the brake lever 12 is elastically mounted on the mounting plate 13 through a compression spring 17 and a screw rod 14.

[0027] When the staff erects the tow bar 5, the pan head screw 9 pushes the screw rod 14, and the screw rod 14 drives the brake rod 12 to move forward and resist the front wheel 3, and at this time the lock hook 10 hooks the hook hole, thereby braking the front wheel 3, and parking is completed at this time.

[0028] When the towing eye 8 is accidentally detached from the airport trailer, the towing bar 5 will fall downward due to gravity, that is, the trailer 1 is not in the parked state. Therefore, the trailer 1 will move randomly due to inertia and may collide with other equipment and facilities. In order to avoid the above situation, the brake mechanism 6 needs to be further improved.

[0029] Please focus on Figure 3-5 The brake mechanism 6 also includes ear plates 11 on both sides of the bottom of the tow bar 5, and limit plates 18 are symmetrically provided on the brake lever 12. The surface of the limit plate 18 is an inclined surface, and the brake lever 16 contacts the inclined surface. At the same time, the brake lever 16 is hinged to the mounting plate 13, and an adjusting screw 15 is installed on the brake lever 16.

[0030] When the tow bar 5 falls, the ear plate 11 comes into contact with the adjusting screw 15, which then drives the brake lever 16 to rotate along the hinge point, thereby driving the brake lever 16 to push the brake lever 12 to move in the through hole and against the front wheel 3, thereby preventing the front wheel 3 from moving and putting the trailer 1 in the parking state; when the tow bar 5 is pulled up, the ear plate 11 is separated from the brake lever 16, so that the brake lever 12 returns to its original state under the spring force of the compression spring 17, and the parking state is released.

[0031] The brake mechanism 6 designed in this device can achieve a dual parking state. It can not only achieve the parking state by actively erecting the tow bar 5, but also achieve the parking state when the tow bar 5 falls accidentally, thereby completely preventing the trailer 1 from being out of control and moving around and colliding with other objects.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
