Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for civil aviation apron baggage consignment, and particularly relates to an auxiliary wheel structure for a non-powered trailer on a civil aviation apron. Background Art

[0002] At present, non-powered trailers are generally used in apron loading and unloading operations to transport various goods, baggage, and mail. Due to problems such as equipment aging and harsh operating conditions, the wheels of the trailers often experience shaking, locking, and falling off. According to statistics, the loading and unloading departments of an airline on average experience more than 30 cases of normal operations being delayed due to damaged wheels of non-powered trailers every month.

[0003] For this problem, the traditional solution is to call a forklift parked in a fixed location to transport the damaged trailer out of the apron operating area. The forklift driver first needs to go to the forklift centralized parking area, then drive the forklift to the vicinity of the damaged trailer, adjust the angle and lift the trailer with the forklift forks and then transport it out of the apron. This process takes a long time, has low efficiency, and high costs. Summary of the Utility Model

[0017] By adopting the above technical solution, it is convenient to arrange the support columns, and when inserting the fixing bolts, it is convenient to insert them and can also hide the position where the fixing bolts are inserted, preventing the fixing bolts from being knocked.

[0018] Optionally, a plurality of support seats are provided, and the plurality of support seats are arranged in alignment.

[0019] By adopting the above technical solution, the plurality of support seats support the trailer, improving the support effect of the auxiliary wheel structure.

[0020] Optionally, the traveling wheel includes a bracket and a hub mounted on the bracket. The bracket includes a connecting plate and mounting plates vertically and fixedly connected to both sides of the connecting plate. The hub is mounted between the two mounting plates, and a rotating shaft is inserted through the two mounting plates and the hub; the connecting plate is rotatably connected to the layout plate.

Detailed Description of the Embodiment

[0031] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the relevant utility model are shown in the drawings.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and embodiments.

[0033] The present utility model provides an auxiliary wheel structure for an unpowered trailer on the civil aviation apron. Referring to Figure 1 , the auxiliary wheel structure for the unpowered trailer on the civil aviation apron includes a walking wheel 1 and a support assembly 2 installed on the upper side of the walking wheel 1.

[0034] Referring to Figure 2, the walking wheel 1 includes a bracket 11 and a hub 12 mounted on the bracket 11. The bracket 11 includes a connecting plate 111 and mounting plates 112 vertically and fixedly connected to both sides of the connecting plate 111. There are two mounting plates 112, and the two mounting plates 112 are arranged in parallel with a gap between them. The two mounting plates 112 are arranged on one side surface of the connecting plate 111. The hub 12 is mounted between the two mounting plates 112, and a rotating shaft 113 is passed through the two mounting plates 112, and the rotating shaft 113 is passed through the hub 12 so that the hub 12 is rotatably connected to the two mounting plates 112.

[0035] Refer to Figure 2 , Figure 3 , the support assembly 2 includes an arrangement plate 21. The arrangement plate 21 is arranged above the connecting plate 111. The arrangement plate 21 is arranged in parallel with the connecting plate 111 and is rotatably connected to the connecting plate 111. The position where the arrangement plate 21 is rotatably connected to the connecting plate 111 is at the center of the arrangement plate 21 and the connecting plate 111, so that the arrangement plate 21 and the connecting plate 111 can rotate horizontally around the connection point, and when the connecting plate 111 rotates, it can drive the wheel roll to rotate relative to the arrangement plate 21.

[0036] A support seat 22 is fixedly connected to the upper side of the arrangement plate 21. There is at least one group of support seats 22. The support seat 22 includes two support columns 221. The support columns 221 are selected as channel steels. The two support columns 221 are arranged oppositely, and the bending directions of the two support columns 221 are arranged away from each other. The support columns 221 are perpendicular to the arrangement plate 21, and there is a gap between the two support columns 221. A support beam 222 that fixedly connects the two support columns 221 together is fixedly connected between the two support columns 221, and the support beam 222 is arranged horizontally.

[0037] Fixing holes 223 are penetrated through the two support columns 221, and the fixing holes 223 on the two support columns 221 are aligned. The position where the fixing holes 223 are opened is above the support beam 222, and multiple fixing holes 223 can be opened on each support column 221. The multiple fixing holes 223 are arranged at equal intervals along the length direction of the support column 221 on the support column 221. Fixing bolts are passed through the fixing holes 223.

[0038] Refer to Figure 1 , Figure 3 , according to different types of trailers, different numbers of support seats 22 can be set for support.

[0039] When a wheel of the container turntable trailer fails, first use a jack to lift the position where the damaged wheel is located, snap the auxiliary wheel structure into the lower edge of the trailer, and make the two support columns 221 clamp the edge of the container turntable trailer and the support beam 222 support the edge of the container turntable trailer, and pass a fixing bolt through the fixing hole 223. When the position where the fixing bolt passes through is higher than the edge of the container turntable trailer, the fixing screw and the support beam 222 restrict the auxiliary wheel structure from detaching from the edge of the container turntable trailer; alternatively, the position where the fixing bolt passes through can be arranged at the edge of the container turntable trailer in a tightly abutting manner, so that the two support columns 221 clamp the edge of the container turntable trailer, thereby fixing the auxiliary wheel structure on the container turntable trailer.

[0040] When the bulk baggage trailer fails, use a jack to lift the position where the damaged wheel is located, snap the auxiliary wheel structure into the lower edge of the trailer, and make the two support columns 221 clamp the edge of the bulk baggage trailer and the support beam 222 support the edge of the bulk baggage trailer, and pass a fixing bolt through the fixing hole 223. Arrange the position where the fixing bolt passes through at the edge of the bulk baggage trailer in a tightly abutting manner, so that the two support columns 221 clamp the edge of the bulk baggage trailer, thereby fixing the auxiliary wheel structure on the bulk baggage trailer.

[0041] When installing the auxiliary wheel structure at the damaged wheel of the trailer, the auxiliary wheel structure and the intact wheel jointly support the trailer. After keeping the overall stability of the trailer, the trailer can be towed out of the apron by a tractor.
