A drainage channel 14 is arranged between the two parallel beam bodies, rainwater flows out through the drainage channel 14, and the influence of accumulated water on electrical equipment of the magnetic suspension train can be greatly reduced.
A plurality of electrical equipment on the track are mainly arranged on the vertical beam 2, and the vertical beam 2 is divided into a plurality of partial areas in order to clarify the inner side surface structure of the vertical beam 2.
The top of the inner side surface of the vertical beam 2 is a guide surface 21 protruding outwards and used for guiding the running track of the train.
The lower part of the guide surface 21 is divided into three areas, and the areas are named as follows from top to bottom: the first region 22, the second region 23 and the third region 24, thereby facilitating a detailed explanation of the specific arrangement of the respective regions to follow.
The vertical beam 2 is provided with a traction coil fixing unit and a magnetic suspension coil fixing unit which are respectively used for installing a traction coil 4 and a magnetic suspension coil 5.
Specifically, the traction coil fixing unit includes: a traction coil bearing lug 231, a traction coil upper positioning bolt 232 and a traction coil lower positioning bolt 233. The magnetic levitation coil fixing unit includes: the middle force bearing projection 234 of the magnetic suspension coil, the bottom force bearing projection 241 of the magnetic suspension coil, the upper positioning bolt 221 of the magnetic suspension coil and the lower positioning bolt 242 of the magnetic suspension coil. The specific position distribution is as follows:
the force bearing convex block 231 of the traction coil and the force bearing convex block 234 of the magnetic suspension coil are both positioned in the second area 23, and the two are distributed in an equidistant and staggered manner in the extending direction of the beam body. The upper positioning bolt 232 of the traction coil and the lower positioning bolt 233 of the traction coil are respectively arranged above and below the force bearing convex block 231 of the traction coil and are both positioned in the second area 23.
The force bearing convex block 241 at the bottom of the magnetic suspension coil is positioned in the third region 24 and is arranged right below the force bearing convex block 231 of the traction coil. The lower positioning bolts 242 of the magnetic levitation coil include a pair, and are respectively disposed at the left and right ends of the force bearing projection 241 at the bottom of the magnetic levitation coil. The positioning bolt 221 on the magnetic coil is located in the first region 22 and corresponds to the positioning bolt 242 on the magnetic coil up and down.
As can be seen from fig. 1: the traction coil 4 and the magnetic levitation coil 5 are overlapped and installed together. The bearing boss design in the scheme can reasonably distribute longitudinal and transverse stress borne by the coil into friction force and constraint force.
Furthermore, as shown in fig. 1 and 2: also disposed within the third section 24 are a signal detection channel 243 and a cable mounting nut 244. The signal detection channel 243 is arranged below the force bearing bump 241 at the bottom of the magnetic levitation coil. The three cable mounting nuts 244 are in a group and are equidistantly arranged right below the force bearing convex block 234 in the middle of the magnetic suspension coil.
A magnetic suspension coil connecting loop channel 15 is also arranged in the linear beam seat 1.
In addition, a positioning instrument mounting nut 13 for mounting a speed measuring and positioning instrument is embedded in the inner side surface of the linear beam seat 1. The beam body limiting bolts 12 are arranged on the inner side edge and the outer side edge of the straight beam seat.
A bagged mortar filling layer 16 is arranged between the linear beam seat 1 and the ground 3. The mortar in the bagged mortar filling layer cannot flow randomly due to the bag body constraint, and is easier to operate and control during construction.
In the scheme, the inverted T-shaped beam body is prefabricated by nonmagnetic steel bars, such as 0Cr16Ni14 nonmagnetic steel bars or basalt fiber composite bars, glass fiber composite bars and nonmagnetic high-strength concrete, such as aggregate without iron ore. The beam body is arranged in a ground roadbed, a bridge or a tunnel.
When the beam body is manufactured, nonmagnetic steel bars are woven and then placed in a mould, concrete is poured for prefabrication, the inverted T-shaped beam body comprises a linear beam and a curved beam, the linear beam is used for a linear line section, the curved beam is used for a lane change or a curved line section, and when the curved beam is prefabricated, the beam body of the curved beam keeps the same radius with the line.
During specific construction, firstly measuring and drawing a line on the ground, positioning the position of the beam body limiting bolt 121, drilling, pouring adhesive glue, and implanting a threaded sleeve. And moving the beam body to the installation part, placing a steel ball or a sliding device with the thickness less than that of the filling layer on the bottom surface of the beam body, moving the beam body front and back and left and right, and screwing a screw rod into the embedded beam body adjusting threaded pipe 122 to perform elevation adjustment and positioning. After the beam body limiting bolt 121 is screwed down, a mortar bag is placed at the beam bottom, mortar is poured into the mortar bag, and the filled beam bottom is full.
Example 2: adopt the type of falling U beam seat, should fall the type of U beam seat and need not adopt the bolt fastening.
Example 2 differs from example 1 mainly in that: the structure of the beam seat.
Example 2 an inverted U-shaped beam seat 1A was used as shown in fig. 3. The structure of the upright beam 2 of the inverted U-shaped beam seat is the same as that of embodiment 1, and the difference between the two will be described below.
Compared with the linear beam seat 1, the inverted U-shaped beam seat 1A does not need to be fixed by bolts, so that the bolts can be greatly saved in practical use, and the construction cost of the magnetic suspension train track beam is reduced. In particular: the longitudinal section of the inverted U-shaped beam seat 1A is in an inverted U shape, so that a cavity is reserved between the bottom of the inverted U-shaped beam seat and the ground plane. The top surface of the inverted U-shaped beam seat 1A is provided with a self-compacting concrete pouring hole 17.
During construction, the self-compacting concrete 32 is poured into the bottom cavity of the beam seat through the self-compacting concrete pouring hole 17, so that the beam seat and the ground embedded steel bar 31 are firmly connected and fixed together. In the fixing scheme, any bolt is not required for fixing, so that the construction cost can be greatly reduced in the whole track laying process, and the economic advantage is very obvious; in addition, this fixed mode compares the mode of bolt fastening more firmly reliable, and bolt fastening life is short, uses the back for a long time, and the very easy emergence is become flexible, and the later stage often needs artifical the maintenance, and maintains with high costs, and this scheme long service life does not need artifical the maintenance basically.
In order to adjust the beam seat during construction, adjusting threaded sleeves 18 are embedded in the inner side surface and the outer side surface of the inverted U-shaped beam seat 1A. When the inverted U-shaped beam seat is installed, the adjusting threaded sleeve 18 can accurately and quickly adjust the height, levelness and other parameters of the beam seat through a matching tool.
Finally, it should be emphasized that, whether a straight beam seat or an inverted U-shaped beam seat is adopted, the wheel rail surface 11 is arranged on the inner side of the top surface of the beam seat, the height of the wheel rail surface 11 is lower than that of the top surface of the beam seat, and the magnetic-levitation train 19 runs on the wheel rail surface 1 in the low-speed stage, as shown in fig. 4. Therefore, in the low-speed running process, accumulated water on the wheel rail surface cannot splash to the inner side surface of the vertical beam 2 to influence the operation of electrical equipment.
