Description
Technical Field
The invention relates to the technical field of normally-conducting magnetic suspension traffic, in particular to an integrated bottom plate device for magnetic suspension train line changing equipment.
Background
The line changing equipment is a large key equipment in a track subsystem in a normally-conducting medium-high speed magnetic suspension traffic system. The line changing equipment realizes the line changing of the train by bending or displacing one main track beam. Such line changing equipment includes switches, transfer tables, and the like. Take the elastic side-bending type turnout as an example:
as shown in figure 1: the turnout consists of a steel beam (a main beam, also called a turnout bending beam) 1 which can be elastically bent, a rotating fulcrum 2 which is arranged on a bottom plate and is provided with a rotating shaft, a plurality of transverse moving fulcrums (also called mobile trolleys) 3 which are arranged on a bottom plate component 4 and are provided with mobile trolleys, a plurality of independent buttress beams 5 which are used for connecting the opening end of the turnout and a circuit behind the turnout, a buttress beam base 6 and the like.
Referring to fig. 3, in the prior art, in order to connect the movable main beam 1 with the adjacent fixed track beam behind the fork, a stack beam 5 with a short length (usually about 1 meter) is arranged at the movable end of the main beam 1. An upper locking assembly 5-1 for positioning the main beam 1 is provided on the pile beam 5. In order to conveniently reserve a space for arranging a ground transverse moving driving assembly 4-2 and a lower locking assembly 4-3 at a transverse moving fulcrum (also called a 'moving trolley') 3 at the end part (see figure 3) of the main beam 1, the main beam 1 needs to extend out of a main beam extension section 1-2 (usually about 1.6 meters) in a cantilever mode towards a pile beam 5 when the line changing equipment is designed. Although the design can meet the functional requirements, the cantilever length of the main beam extension section 1-2 cannot participate in bending so as to form a lateral direction line shape of the turnout, and the length is wasted. It not only increases the length of the turnout, but also increases the manufacturing cost of the turnout. This problem has not been solved in the prior art designs. Meanwhile, as the stacking beam 5 is designed to be equal to the main beam 1 in height, a set of stacking beam base 6 with a stacking beam mounting plate 6-1 is specially designed to fill the height difference of the lower part. Therefore, the manufacturing cost of the turnout is increased again, and each pile beam 5 needs to be accurately positioned during installation, so that the difficulty of site construction is increased, the construction period is prolonged, and the overall construction cost of the turnout is further increased.
In addition, the lower lock sensor assembly 4-6 for detecting the protruding latch lever of the lower lock device in the conventional design is designed to be installed under the latch lever near one side of the buttress beam and in the upward direction of the contact. When a fault that a return spring inside the assembly fails (cannot rebound back to the original state) occurs, the collision head falls due to gravity to cause the sensor assembly to send out an incorrect locked instruction, and the risk in the aspect of signal safety exists.
