The specific meaning of the above terms in the present embodiment can be understood in a specific case by those of ordinary skill in the art.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
When the extending direction of the railway and the length direction of the stool Liang Tiaoji have an oblique angle, and the train passes through the stool beams between the stools Liang Tiaoji, the stool beams under the wheels on one side of the train are supported by the stool Liang Tiaoji, and the stool beams under the wheels on the other side of the train are not supported by the stool Liang Tiaoji in certain positions, so that the stress of the two longitudinal beams of the stool beams is uneven and the deflection of the beams is asynchronous. Therefore, the railway track supported by the temporary beam can be influenced by different supporting forces of the two longitudinal beams of the temporary beam to generate the problem of unsmooth left and right running, so that the two tracks of the railway are easy to have height difference, and vehicles on the left side and the right side of a passing train are also caused to have height difference, so that the running speed and the stability can be influenced, and meanwhile, the potential safety hazard is also caused.
In order to solve the problems that in the prior art, an oblique angle is formed between the extending direction of a railway and the length direction of a stool Liang Tiaoji, and the deflection of two longitudinal beams of the stool beam between strip bases is asynchronous when a train passes, so that horizontal irregularity and triangular pits exist on a rail of the stool beam, and a certain height difference exists between wheels on the left side and the right side, and the running speed, stability and safety are influenced, the embodiment of the invention provides a support structure of the stool beam.
Further, referring to fig. 2, in the support structure for a stool beam according to the embodiment of the present invention, a railway is erected on a stool beam 1, the stool beam 1 is disposed on a top surface of a stool Liang Tiaoji, and the railway includes a first track and a second track parallel to each other, the stool beam includes two stringers, an extension direction of the railway is the same direction as an extension direction of the stool beam, and an oblique angle is formed between the extension direction of the stool beam and a length direction of the stool Liang Tiaoji 2. Because of the skew angle, when the train passes through the stool Liang Tiaoji, for example, the position where the straight line perpendicular to the extending direction of the stool beam 1 is determined by the point A and the point B, the downward deflection deformation generated by the side of the stool beam A under the pressure of the wheels of the train is smaller than the downward deflection deformation of the side of the point B, and therefore, the wheels on two sides of A, B have a certain height difference.
Further, referring to fig. 2, in the support structure of the toilet beam according to the embodiment of the present invention, the support structure is disposed below the toilet beam 1 in a vertical direction, and includes: the support cross bar 3, the support cross bar 3 is disposed along a direction parallel to the extending direction of the stool beam 1, and one end of the support cross bar 3 is located at an obtuse angle skew angle vertex position of the stool beam 1 and the stool Liang Tiaoji, and the other end is located at a position of the stool beam 1 away from the stool Liang Tiaoji 2 and a preset distance from the obtuse angle skew angle vertex, and the support cross bar 3 supports the corresponding portion of the stool beam 1. Wherein the preset distance is the distance between the other end of the support cross bar 3 and the apex of the obtuse angle bias angle in the horizontal direction. The distance range may be determined in accordance with the length between the intersection of one of the longitudinal beam first tracks of the stool beam 1 and the stool Liang Tiaoji, the intersection of the other longitudinal beam second track of the stool beam 1 and the stool Liang Tiaoji 2, and the width between the two longitudinal beam first tracks and the second track of the stool beam 1, which will be described in detail later. More specifically, the support rails 3 in fig. 2 are provided in two, one on the left side of the stool Liang Tiaoji and the other on the right side of the stool Liang Tiaoji 2. When the support cross bar 3 is arranged, the support cross bar 3 can be arranged on one side of the stool Liang Tiaoji to save cost, but the support cross bar 3 is arranged on two sides of the stool Liang Tiaoji to improve the support effect. The support cross bar 3 supports the corresponding portion of the stool beam 1, i.e., the support cross bar 3 supports the stool beam 1 in a range from an obtuse skew angle vertex to a preset distance from the obtuse skew angle vertex. I.e. the support rail 3 supports the walking beam 1 over its length.
Further, referring to fig. 3, in the support structure for a toilet beam according to the embodiment of the present invention, the support structure further includes at least one support diagonal 4, and one end of each support diagonal 4 is fixed to one side of the toilet Liang Tiaoji adjacent to the support rail 3, and the other end is fixedly connected to the support rail 3 so as to support the support rail 3 with respect to the toilet Liang Tiaoji. In particular, the support diagonal bars 4 are provided for supporting the support rail 3, the number of which may be set to one, two or even more. No matter how the support diagonal 4 is arranged, the support diagonal 4 and the support cross bar 3 generally form a triangular structure for better support. More specifically, the manner in which one end of the supporting diagonal rod 4 is fixedly connected with the stool Liang Tiaoji 2 and the manner in which the other end of the supporting diagonal rod 4 is fixedly connected with the supporting cross rod 3 include, but are not limited to, welding, threaded connection, and integral molding. While the support cross bar 3 can be in contact with the stool beam 1 only, a connecting piece, such as a binding belt, can be arranged to make the support of the support cross bar 3 to the stool beam 1 more stable.
Furthermore, in the support structure for the toilet beam according to the embodiment of the present invention, the support cross bar 3 is provided to support the corresponding portion of the toilet beam 1, so that the wheels on the first side and the wheels on the second side can be changed into the wheels on both sides to be supported when the train passes through due to the support cross bar 3 provided to support the toilet beam 1 even if the extending direction of the toilet beam 1 and the length direction of the toilet beam Liang Tiaoji have an oblique angle. Therefore, when a train passes through the temporary beam 1, the deflection of the two longitudinal beams of the temporary beam 1 is synchronous, and when the train passes through the temporary beam 1, the forces of the wheels on the left side and the right side of the train at any position are the same, the height difference between the two rails of the railway is avoided, and the running stability and the running safety of the train are improved.
Further, referring to fig. 4, in the support structure of the toilet beam according to the embodiment of the present invention, at least one support diagonal 4 is provided in pairs and includes at least a pair of distal support diagonal. One end of each of the two distal support diagonal rods is fixed at the vertex position of the acute angle skew angle between the stool beam 1 and the stool Liang Tiaoji. And, the other end of a distal end support diagonal is fixedly connected with the other end of the support cross bar 3, and the other end of the other distal end support diagonal is positioned between one end and the other end of the support cross bar 3. In particular, the distal support diagonal is in the same horizontal plane as the support rail 3, i.e. supports the support rail 3 in the horizontal direction.
Still further, with such an arrangement, since the distal support diagonal supports the support rail 3 in a horizontal direction, the distal support diagonal can support the support rail 3 with little space, facilitating the placement of other structures below the walking beam 1.
Still further, referring to fig. 5, in the support structure for a toilet beam according to the embodiment of the present invention, at least one support diagonal 4 further includes at least one pair of intermediate support diagonal. One end of one middle supporting diagonal rod and one end of the other middle supporting diagonal rod are fixed at the same position of one side, close to the supporting cross rod 3, of each middle supporting diagonal rod Liang Tiaoji, and the other ends of the two middle supporting diagonal rods are fixedly connected with corresponding positions of the supporting cross rod 3 and are spaced by a preset distance. Wherein the preset distance is a distance between the other ends of the two intermediate support diagonal rods in each of the intermediate support diagonal rods in the horizontal direction. This distance range can be determined by the person skilled in the art based on the length of the support rail 3, in combination with the number of intermediate support diagonal rods and other requirements. Further, the plurality of intermediate support diagonal members are sequentially and uniformly aligned in the longitudinal direction of the stool Liang Tiaoji at a plurality of fixed positions with respect to the stool Liang Tiaoji 2. Specifically, the intermediate support diagonal supports the support rail 3 in the vertical direction. The interval distance between the other ends of the two middle supporting diagonal rods in each middle supporting diagonal rod can be set according to actual requirements, and in order to improve the stability of the support, one end of one middle supporting diagonal rod can be arranged at the left side of the middle point of the supporting cross rod 3, and one end of the other middle supporting diagonal rod is arranged at the right side of the middle point of the supporting cross rod 3; or one end of one middle supporting diagonal rod is arranged at the position of the other end of the supporting cross rod 3, and one end of the other middle supporting diagonal rod is arranged at the midpoint position of the supporting cross rod 3.
