Embodiment Construction

[0018] like Figure 1 to Figure 3 The shown lateral pressure device for laying ballastless track sleepers has a door-shaped bracket, and the door-shaped bracket includes a first side column 1, a top beam 2, and a second side column 4 that are sequentially fixedly connected. The length of the side column 1 is shorter than the length of the second side column 4, and the second side column 4 has a boss 5 protruding to both sides away from the end of the top beam 2, so that the width of the second side column 4 away from the end of the top beam 2 Greater than the width of other parts of the second side column 4 . The top beam 2 has an axial waist-shaped hole; the screw rod 3 of the first bolt assembly passes through the waist-shaped hole, and the head of the screw rod 3 is a square head, which can apply a large external force. When in use, the first bolt The outer surface of the part where the screw 3 of the component is implanted into the concrete is coated with planting glue. D...

Abstract

The invention discloses a side compression device for laying a ballastless track sleeper. The device comprises a door-shaped support, a first bolt assembly and at least one set of second bolt assembly, wherein the door-shaped support is provided with a first side column (1), a top beam (2) and a second side column (4) which are sequentially and fixedly connected; the top beam (2) is provided with an axial slotted hole; a threaded rod (3) of the first bolt assembly penetrates through the slotted hole, and a nut (9) of the first bolt assembly is positioned on the outer side of the top beam (2) of the door-shaped support; and a threaded rod (6) of the second bolt assembly passes through the nut to be hinged with the second side column (4). The provided side compression device is contributed to improving the precision when a ballastless track sleeper is laid.

Description

technical field [0001] The invention relates to the technical field of ballastless track sleeper laying, in particular to a lateral pressure device for laying ballastless track sleepers which can improve the laying accuracy of the sleeper. Background technique [0002] The railway sleeper is placed under the rail, which supports the rail and spreads the load on the rail to the ballast bed. It is an important part of the railway track. The sleeper plays the role of fixing the position of the rail and maintaining the gauge. The demand for sleepers is large, so the raw materials should be rich in sources and moderate in price. Because concrete sleepers have the characteristics of high strength, large lateral resistance of the ballast bed, good stability, and long service life, and are not affected by climate and corrosion, and can save a lot of high-quality wood, they have been widely used in railway construction. [0003] Ballastless track has the advantages of good track smo...
