Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, this embodiment discloses a universal bracket for a seamless track locking rail temperature measuring instrument, comprising:

[0025] Connecting bracket 3, in this embodiment, an aluminum alloy bracket is used;

[0026] Two road spike support blocks 1, which are respectively arranged at two ends of the connecting bracket 3;

[0027] The force adding device is arranged in the middle of the connecting bracket 3.

[0028] The two ends of the connecting bracket 3 are respectively provided with through spike support block limiting grooves 31, and the spike support block 1 is limited and set within the range of the spike support block limiting grooves 31. In this embodiment, a tensioning device 32 is also included, and the spike support block 1 is limited and set within the range of the spike support block limiting grooves 31 through the tensioning device 32. When the tensioning device 32 is in a loose state, the spike support block 1 can move in the spike support block limiting grooves 31; when the tensioning device 32 is in a tightened state, the spike support block is fastened in the spike support block limiting grooves 31. In this embodiment, the tensioning device 32 is a screw nut, and the interior of the spike support block limiting grooves 31 is provided with threads. When the screw nut is in a loose state, the spike support block 1 can move in the lateral direction of the spike support block limiting grooves 31, which is used to adjust the lateral distance between the two spike support blocks 1, so as to match different models of track spikes or tracks with different spacings.

[0029] A first fixing through hole 51 is provided in the middle of the connecting bracket 3, and the force device includes a force threaded rod 4 and a force support block 5. A second fixing through hole 52 is provided at the lower end of the force support block 5. The first fixing through hole 51 is matched with the second fixing through hole 52. When the force support block is in the working state, the second fixing through hole 52 corresponds to the position of the first fixing through hole 51. Then, the force support block 5 is fixedly set in the middle of the connecting bracket 3 by screws, wherein the screws penetrate the first fixing through hole 51 and the second fixing through hole 52. The upper end of the force support block 5 includes a threaded hole 53, and the force threaded rod 4 is connected to the force support block 5 through the threaded hole 53.

The remaining operations can be performed by technicians in this field according to actual needs.

[0031] In other embodiments, the force adding device further includes a force adding wrench 6, which is arranged at one end of the force adding threaded rod 4. Preferably, the force adding wrench 6 and the force adding threaded rod 4 are integrally formed.

A positioning hole 12 is drilled and tapped on the opposite side of the spike support block 1, and a screw 2 is used as a positioning screw to prevent it from falling on the aluminum alloy bracket and to slide freely on the aluminum alloy bracket. A spike hole 13 is opened on the other side of the spike support block 1 for installing a line spike. The diameter of a conventional railway line spike is 24 mm, so the diameter of the spike hole 13 is preferably 24 mm.

[0035] like Figure 3As shown (the left side is a top view, the right side is an AA cross-sectional view), the connecting bracket 3 is provided with two spike support block limiting grooves 31 for fixing the spike support block 1, one on each side, for a total of two. A first fixing through hole 51 is drilled in the center of the connecting bracket 3, and the force support block 5 is fixed by screws to prevent it from falling on the connecting bracket 3, and can slide freely on the aluminum alloy support rod.

[0036] like Figure 4 As shown (the left side is a top view, the right side is an AA cross-sectional view), the force support block 5 is provided with a square hole 54, and the square hole 51 matches the cross section of the connecting bracket 3, so that the force support block 5 can be installed on the aluminum alloy bracket. A second fixing through hole 52 is drilled and tapped on the opposite side of the force support block 5, and a positioning screw 8 is used to prevent it from falling on the aluminum alloy bracket and fixed in the middle position of the aluminum alloy bracket.
