Abstract
The utility model provides a tram contact net is with hanging anchor post, including a cavity stand, the upper end is provided with roll-up mechanism in the stand, roll-up mechanism with set up in compensation arrangement in the stand is connected, the stand bottom is provided with and is used for preventing that compensation arrangement from dropping the buffer of damage, and the stand inboard is provided with the slide rail. The beneficial effects of the utility model are embodied in: the utility model discloses under emergency, provide compensation arrangement's brake function through roll-up mechanism to reduce the damage that the weight caused. When the contact net broken string, provide the buffering through the buffer, prevent that compensation arrangement from damaging, better improvement on-the-spot efficiency of salvageing, and can prevent compensation arrangement jamming through stand inboard slide rail.
Description
Technical Field
The utility model relates to a tram is suspension anchor post for contact net.
Background
The overhead contact system is a main framework of the railway electrification engineering and is a special power transmission line which is erected along a railway line and supplies power to an electric locomotive. It is a high voltage transmission line which is erected along a zigzag shape above a steel rail in an electric railway and is used for a pantograph to draw current. The existing tramcar contact net is generally hung on an anchor column, a pulley compensation device is installed at the lower anchor part of a cable at two ends of an anchor section, and the tension of the cable is automatically adjusted and the cable sag is kept to meet the required technical requirements under the action of the gravity of a balance weight string.
However, the conventional anchor column may cause the falling weight of the compensating device to be blocked due to factors such as burrs on the inner wall of the strut and the like, so that the vertical movement of the compensating device is influenced, and the actual compensating effect is influenced; the situation of disconnection of a contact network can also exist, so that the compensation device falls to the bottom of the support to cause damage; the disconnection of the contact system may also result in failure to provide the braking function.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough of prior art, the utility model provides a tram is suspension anchor post for contact net.
The purpose of the utility model is realized through the following technical scheme:
tram is suspension anchor post for contact net, including a cavity stand, the upper end is provided with roll-up mechanism in the stand, roll-up mechanism with set up in compensation arrangement in the stand is connected, the stand bottom is provided with and is used for preventing that compensation arrangement from dropping the buffer of damage.
Preferably, the inner side of the upright post is provided with a slide rail, and two sides of the compensation device are arranged in the slide rail.
Preferably, the compensation device is formed by stacking a plurality of balance weights layer by layer.
Preferably, the buffer is a polyurethane buffer.
Preferably, a pulley block is arranged on the outer side of the upright post, the pulley block is connected with the compensating device through a rope, and the other end of the pulley block is connected with a contact net.
Preferably, the pulley block is arranged between the winding mechanism and the compensating device.
The beneficial effects of the utility model are embodied in: the utility model discloses under emergency, provide compensation arrangement's brake function through roll-up mechanism to reduce the damage that the weight caused. When the contact net broken string, provide the buffering through the buffer, prevent that compensation arrangement from damaging, better improvement on-the-spot efficiency of salvageing, and can prevent compensation arrangement jamming through stand inboard slide rail.
Drawings
FIG. 1: the structure of the utility model is schematically shown.
Detailed Description
Following combination embodiment specifically explains the technical scheme of the utility model, the utility model discloses a tram is suspension anchor post for contact net combines figure 1 to show, including a cavity stand 1, the upper end is provided with roll-up mechanism 3 in the stand 1, roll-up mechanism 3 with set up in compensation arrangement in the stand 1 connects 4, for avoiding because factors such as burr exist in 1 inner wall of pillar jamming when causing compensation arrangement activity, 1 inboard of stand is provided with slide rail 11, compensation arrangement 4's both sides are arranged in the slide rail 11. The bottom of the upright post 1 is provided with a buffer 5 for preventing the compensation device 4 from falling and being damaged. The outer side of the upright post 1 is provided with a pulley block 2, the pulley block 2 is connected with the compensating device 4 through a rope 21, and the other end of the pulley block 2 is connected with a contact net. The pulley block 2 is arranged between the winding mechanism 3 and the compensating device 4. The compensation device 4 is connected with the furling mechanism 3 through a thread, and the thread is larger than the linear distance between the compensation device 4 and the furling mechanism 3.
In this embodiment, the compensation device 4 is formed by stacking a plurality of balance weights layer by layer. The buffer 5 is a polyurethane buffer.
The utility model discloses under emergency, provide through roll-up mechanism 3 compensation arrangement's braking function to reduce the damage that weighs down the stone roller and cause. When the contact net is disconnected, the polyurethane buffer can be fine provide the buffering, prevents that compensation arrangement from damaging, also can be better improvement on-the-spot efficiency of salvageing. The utility model discloses a pulley block and compensation arrangement realize adjusting the tension of clue and keep the principle of clue sag the same with current implementation, so no longer give unnecessary details here.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Of course, the present invention has many specific embodiments, which are not listed here. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
