Description

Technical Field

[0001] The utility model relates to a field, in particular to a roller - type buffer device for airport luggage carousels. Background Art

[0002] For the existing luggage carousel in the airport, when the conveyor belt transports the luggage to the inclined luggage carousel, due to the influence of gravity and the slope, the luggage will slide down rapidly and hit the edge below the slope violently, causing certain damage to the luggage and the items inside. For this reason, some airports have set up baffles at this place. The main purpose of this baffle is to prevent the luggage from rushing out of the luggage carousel and falling to the ground. When the luggage slides down, it directly hits the trapezoidal protrusions at the lower end of the inclined carousel conveyor belt. Therefore, such baffles cannot play a role in buffering the impact.

[0003] The existing baffles may also affect the conveyance of the luggage that has not been taken away in time and circulates back on the carousel, and even cause stagnation due to the mutual extrusion of these luggage and the luggage sliding down from above. Therefore, some airport staff will stand at this position and gently catch the sliding luggage one by one by hand.

[0004] Therefore, it is necessary to design a reasonable device that can both buffer and support the sliding luggage above, and can smoothly transition the luggage that has not been taken away in time and circulates back from the side. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems in the prior art and provide a roller - type buffer device for airport luggage carousels.

[0006] To achieve the above - mentioned purpose, the utility model adopts the following technical solutions:

[0007] The roller - type buffer device for airport luggage carousels includes elastic rollers, shock absorbers, bearings, shafts, roller fixing frames, and a support frame; there are two roller fixing frames, which are arranged in parallel and are arranged inside the support frame; there are multiple elastic rollers, which are arranged side by side inside the two roller fixing frames. The two ends of the elastic rollers are provided with the shafts, the shafts are connected to the roller fixing frames, and bearings are arranged between the shafts and the elastic rollers to enable the elastic rollers to rotate; a plurality of shock absorbers are evenly arranged at the bottom of the roller fixing frames, and the shock absorbers are connected to the bottom of the support frame.

[0008] The utility model further includes a connecting rod, the two ends of the connecting rod are fixed to the bottom of the roller fixing frame, and the shock absorbers are arranged on the connecting rod.

[0009] The utility model further includes universal ball wheels, and the universal ball wheels are arranged on the outer side of the roller fixing frame or the inner side of the support frame.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further describes the present utility model in detail with reference to the drawings and embodiments.

[0024] Such as Figures 1 to 5As shown in the figure, this embodiment includes an elastic roller 1, a roller fixing frame 2, a support frame 3, universal ball wheels 4, and shock absorbers 5;

[0025] There are two roller fixing frames 2, which are arranged in parallel and are disposed within the support frame 3;

[0026] In this embodiment, there are 16 horizontally arranged elastic rollers 1, which are disposed within the two roller fixing frames 2, and a part of the arc of the elastic roller 1 is higher than the roller fixing frame 2; shafts are provided at both ends of the elastic roller 1, the shafts are connected to the roller fixing frame 2, and bearings are provided between the shafts and the elastic roller 1 to enable the elastic roller 1 to rotate;

[0027] A plurality of connecting rods are provided at the bottom of the roller fixing frame 2, and both ends of the connecting rods are fixed to the bottom of the roller fixing frame 2, and the shock absorbers 5 are disposed on the connecting rods; in this embodiment, 6 shock absorbers 5 are evenly arranged, and the shock absorbers 5 are connected to the cross bar at the bottom of the support frame 3;

[0028] A plurality of universal ball wheels 4 are provided, which are disposed on the outer side of the roller fixing frame 2 or the inner side of the support frame 3, and can both support and reduce the friction with the support frame 3. In this embodiment, the universal ball wheels 4 are disposed on the inner side of the support frame 3.

[0029] Limit rods are further provided around the support frame 3 to prevent the elastic roller 1 from deviating.

[0030] The elastic roller 1 is a hollow rubber rod, which is very wear-resistant and scratch-resistant. The key is that it has great elasticity, which can not only eliminate the collision grooves but also buffer the impact with an elastic material; the shafts, roller fixing frames, and support frames are made of aluminum alloy material.

[0031] The elastic roller 1 is fixed to the support frame 3 through the shock absorbers 5. When under pressure, it will compress the springs of the shock absorbers 5 and drop as a whole, and return to its original state without pressure. The interval between each elastic roller 1 is 5 mm, and each elastic roller 1 can roll easily under the action of an external force. The outer diameter of the elastic roller 1 is 60 mm, the inner diameter is 20 mm, and the length is 250 mm; the shaft is made of an aluminum alloy hollow tube, with an outer diameter of 20 mm, an inner diameter of 15 mm, and a length of 250 mm; the outer diameter of the bearing is 15 mm, and the inner diameter is 6 mm; the length of the roller fixing frame 2 is 1000 mm, the width is 50 mm, and the thickness is 4 mm.

[0032] The shock absorber 5 is composed of a spring and a shock absorber cylinder, with a compression stroke of 40 mm, and the shock absorbers 5 are arranged in groups of two.

[0033] The function of the support frame 3 is to connect and carry the elastic roller 1 through the shock absorber 5. Three horizontal bars made of aluminum alloy at the bottom fix three groups of springs. The limiting rods around the perimeter surround the elastic roller 1 but do not contact it. The height of the roller fixing frame 2 is lower than that of the elastic roller 1, leaving enough reciprocating stroke for the elastic roller 1.

[0034] The height of the universal ball wheel 4 is 14 mm. Its function is to prevent the elastic roller 1 from sagging due to gravity during use, providing a supporting role, and also reducing the friction between the elastic roller 1 and the support frame 3 during reciprocating motion.

[0035] The usage method and principle of the present utility model are as follows:

[0036] See Figure 6 , design the bracket according to the inclination angle of the airport conveyor belt so that the elastic roller 1 is perpendicular to the conveyor belt of the airport turntable, which can better buffer and transition the luggage; during actual installation, the existing baffle at the airport can be replaced with this device, and the installation method can refer to the installation effect of the airport baffle. Install the present utility model at the edge of the inclined conveyor turntable at the airport, with the elastic roller 1 facing the exit direction of the upper luggage conveyor belt. Through the action of the elastic roller 1 and the shock absorber 5, the impact of the sliding luggage is reasonably buffered. When the luggage circulating from the side passes through the device, since the elastic roller 1 is internally equipped with a bearing and can rotate passively, when the luggage circulating back from the side on the turntable passes through the device, the passive feature of the elastic roller 1 can reduce the friction with the luggage, enabling the luggage to pass through the device smoothly without causing obstruction or stagnation.

[0037] The present utility model combines the shock absorber with the elastic roller 1. The elastic roller 1 can support the luggage in a soft contact manner, realizing buffer support and reducing the violent impact and vibration of the luggage; the elastic roller 1 is equipped with a bearing inside, which can make the elastic roller 1 rotate passively. When an object passes horizontally through the roller, it drives the elastic roller 1 to rotate, and the friction between them is very small. Therefore, the luggage circulating back from the side will not be dragged to a stop but will smoothly transition through the passive rotation of the roller.
