More preferably, as shown in fig. 5(a) and 5(b), in order to facilitate the insertion of the head 1031 of the T-shaped wedge 103 into the first through-hole 109, the first through-hole 109 may be designed such that its central axis is not parallel to the planar bottom end surface of the first support plate 101, but rather, the central axis of the first through-hole of the first support plate 101 intersects the bottom end surface of the first support plate at an angle along an extension line extending in the direction from the convex surface to the concave surface.

In a preferred embodiment, both the first support and the second support may be welded to the tie 113.

The rail fixing device 100 according to the above-described embodiment of the present invention may be applied to an adhesive tape machine, but the present invention is not limited thereto, and the rail fixing device 100 according to the above-described embodiment of the present invention may also be applied to fix rails in other rail-type equipment, such as rails for railways.

The following describes, by way of example, a rail fixing device 100 according to an embodiment of the present invention.

As shown in fig. 2, the first support plate 101 and the second support plate 102 may be welded on both sides of the sleeper 113 of the intermediate frame 112, and the T-shaped wedge 103 may be inserted into the first support plate 101. The rail 111 is placed on the intermediate frame tie 113 and may be placed between the first support plate 101 and the second support plate 102 and one side of the rail 111 may be clamped under the T-shaped wedge 103. The pressing plate 104 can be placed between the two second supporting plates 102 and pressed against the other side of the rail 111, and then the pin 105 can be inserted through the two second supporting plates 102 and the pressing plate 104 and fixed by the cotter pin 106. As shown in fig. 3, a set of limiting plates 107 may be disposed on two opposite sides of each tie 113 in the length direction of the rail, each limiting plate 107 may be fixed to the rail 111 by a fastener 108, and a certain deformation margin may be left between the limiting plate 107 and the tie 113. The fasteners 108 may include, for example, bolts, nuts, and washers.

During the transfer, the fixed rail 110 and the intermediate frame 112 are lifted by the lifting transfer machine and then transferred to the designated position step by step. The pressing plate 104 and the T-shaped wedge 103 can limit the rail 111 to move up and down, the first support plate 101 and the second support plate 102 can limit the rail 111 to move along the width direction of the rail 111, and the limiting plate 107 can prevent the rail 111 from moving along the length direction. During disassembly, the T-shaped wedge 103 can only be removed after the cotter pin 106 and the pin 105 are pulled out, the press plate 104 is removed, and the rail 111 is lifted out. If the T-shaped wedge 103 is taken first, the T-shaped wedge 103 will touch the steel rail 111 in the process of pulling the T-shaped wedge 103, and the T-shaped wedge 103 can not be pulled out due to the interference effect of the steel rail 111.

The lengthened design of the tail 1033 of the T-shaped wedge 103 of FIG. 4 increases the structural strength and increases the contact area with the rail 111; the middle section 1034 may be a near cone, and thus may rotate in the first support plate 101, facilitating penetration; the design of the ramp structure 1035 may facilitate insertion and angle adjustment of the T-shaped wedge 103 into the first support plate 101; the head 1031 is square and designed to be chamfered so as to be easily inserted into the first center through hole 109 of the first support plate 101, and the lower end of the head 1031 is provided with a barb structure 1032, wherein the barb structure 1032 can be caught at the lower portion of the first center through hole 109 of the first support plate 101 if the T-shaped wedge 103 is directly pulled out.

Furthermore, the T-shaped wedge 103 can be installed by bare hands without using tools during installation, and the T-shaped wedge 103 cannot be directly disassembled after the track is fixed, so that a locking effect is achieved; the T-shaped wedge 103 can be taken out only by removing the pressing plate 104 on the other side of the track and removing the steel rail 111, so that the T-shaped wedge 103 can not fall off when track equipment such as a tape machine and the like normally runs, and the track can be tightly locked when the T-shaped wedge is moved.

Fig. 6 schematically illustrates the process of inserting the T-shaped wedge of fig. 4 into the first support plate of fig. 5. First, as shown in fig. 6(a), a T-shaped wedge 103 is brought close to a first support plate 101; next, as shown in fig. 6(b), the T-shaped wedge 103 is horizontally inserted into the first central through hole 109 of the first support plate 101 until it is immovably inserted against the hole wall; next, as shown in fig. 6(c), the T-shaped wedge 103 is inclined downward by a certain angle and inserted further inward; next, as shown in fig. 6(d), the T-shaped wedge 103 is rotated while continuing to be inserted inward until it is completely inserted into the bottom of the first support plate 101.
