Description

Technical Field

[0001] The utility model belongs to the technical field of tram, and particularly relates to a clearance eliminator for tram. Background Art

[0002] The clearance eliminator is a common device applied to the bottom of the tram. Its main function is to block and discharge the obstacles invading the vehicle gauge under the vehicle, so as to protect the equipment under the vehicle. Since the driving road conditions of the tram are mostly on the ground surface, and some areas are mixed traffic roads, there are large possibilities of sundries on the road surface.

[0003] At present, most of the clearance eliminators for trams have a simple structure. Its structure usually includes a mounting seat for connecting to the tram and a long strip of simple rubber strip. In actual application, it is found that when the rubber strip is blocked by an obstacle and broken, the whole needs to be replaced. Such replacement has the following disadvantages: First, from the perspective of maintenance economy, such maintenance requires the replacement of the whole rubber strip, and the economy is not high; at the same time, from the perspective of the difficulty of maintenance, the long rubber strip is fastened by multiple fixing bolts, and the disassembly and assembly are relatively cumbersome and difficult; furthermore, from the perspective of the actual application function effect, due to the simple shape of the rubber strip, it cannot effectively block or remove specific obstacles from the safety gauge, and its practicability is not ideal. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide a clearance eliminator for tram, which can effectively remove the obstacles of the tram and is more convenient for subsequent maintenance.

[0005] The purpose of the utility model is realized by the following technical solutions:

[0006] The clearance eliminator for tram includes at least one clearance elimination unit. The clearance elimination unit includes a hollow shell. An opening and closing lock is connected to the shell through a rotating shaft. One end of the opening and closing lock is clamped with a clearance elimination rod. One side of the clearance elimination rod is abutted against the shell through an elastic component.

[0007] Preferably, the elastic component includes a spring and a slider connected to one side of the spring. One side of the slider is abutted against the clearance elimination rod. When the clearance elimination rod is forced to press, it can move horizontally under the action of the elastic component.

[0008] Preferably, the opening and closing lock is in a hook shape. One end is connected to the shell through a rotating shaft, and the other end hooks the upper end of the clearance elimination rod. The opening and closing lock rotates circumferentially along the rotating shaft.

[0009] Preferably, a strip-shaped cavity is arranged in the shell, and the elastic component is arranged in the cavity.

[0010] Preferably, the bottom of the obstacle removal rod is a rubber part, and the bottom of the obstacle removal rod is bent towards the elastic component side to form a wedge shape.

[0011] Preferably, the outer edge of the bottom of the rotating shaft end of the opening and closing lock is provided with a rounded corner.

[0012] Preferably, more than one obstacle removal unit is provided, and adjacent obstacle removal units are connected by a housing and arranged in parallel. One side of the obstacle removal units at both ends is respectively connected to the tram by a connecting plate.

[0013] The beneficial effects of the present utility model: The present utility model is of a detachable type, which is convenient for disassembly and installation for component replacement during later maintenance. At the same time, the combined use of obstacle removal units also avoids the replacement of the whole, saving not only maintenance time but also maintenance costs, and has strong practicability.

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the Figures 1-5 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The utility model discloses an obstacle eliminator for a tram, which comprises at least one obstacle elimination unit. The obstacle elimination unit includes a hollow shell 1. Inside the shell 1, an opening and closing lock 2 is connected through a rotating shaft 11. One end of the opening and closing lock 2 is clamped with an obstacle elimination rod 3. One side of the obstacle elimination rod 3 is abutted against the shell 1 through an elastic component. Specifically, the shell includes side walls on the front and rear sides. For the convenience of assembly, the height of one side wall is lower than that of the other side. The rotating shaft 11 is vertically connected to the inner wall 13 on one side of the shell 1, and the rotating shaft 11 is exposed outside the shell 1. A strip-shaped cavity 12 is arranged below the rotating shaft 11. The elastic component is placed in the strip-shaped cavity 12. The elastic component includes a spring 5 and a slider 4 connected to one side of the spring 5. One side of the slider 4 is abutted against the obstacle elimination rod 3. Of course, the elastic component can also be in the form of a spring alone.

[0022] The opening and closing lock 2 is in a hook shape, and the obstacle elimination rod 3 is in a T shape. One end of the opening and closing lock 2 is connected to the shell 1 through the rotating shaft 11, and the other end hooks the upper end 32 of the obstacle elimination rod 3. The other end of the upper end 32 of the obstacle elimination rod is erected on the upper surface 121 of the strip-shaped cavity 12. The outer edge 21 at the bottom of the rotating shaft end of the opening and closing lock 2 is rounded. The opening and closing lock 2 rotates circumferentially along the rotating shaft 11. When the obstacle elimination rod is forced to be pressed, it can move horizontally under the action of the elastic component.

[0023] The bottom 31 of the obstacle elimination rod 3 is a rubber part. In this embodiment, the bottom of the obstacle elimination rod 3 is bent towards the elastic component side to form a wedge shape. During use, the bent wedge part faces forward to eliminate obstacles on the road surface. Of course, the obstacle elimination rod 3 can be made of rubber as a whole, and the bottom shape of the obstacle elimination rod 3 can be set in different shapes and structures according to actual needs. Since components such as the obstacle elimination rod in the utility model are all separately detachable components, different shape replacements can be made according to actual use scenario requirements. And because the obstacle elimination rod 3 is most vulnerable to damage during use, it can also be replaced separately during later maintenance to reduce costs. During disassembly, the obstacle elimination rod 3 is pushed towards the elastic component direction to compress the spring. At this time, the upper end of the obstacle elimination rod 3 will be disengaged from the hook-shaped end of the opening and closing lock 2 to unlock, and the opening and closing lock 1 can rotate around the rotating shaft 11, so as to remove the obstacle elimination rod 3 for replacement.

[0024] During use, the unit of the utility model can be used alone in a single form. It can also be used in combination as Figure 5 shown. The obstacle elimination units are connected through an outer shell and arranged side by side. One side of the obstacle elimination units at both the head and the tail is respectively connected to the tram through a connecting plate. The connection can be in ways such as welding or threading, which is not limited here.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0026] There are many specific application examples of the present utility model. The above description is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements can still be made, and these improvements should also be regarded as the protection scope of the present utility model.
