[0029] The utility model provides a multifunctional clamp for a railway freight car saddle, which includes a device crossbeam, an adjustment hook rod, an adjustment rod and a support plate. Figure 1 To Attachment Fig. 9 , and provide a detailed description of each component.

[0030] The crossbeam 10 is made of a steel beam with sufficient rigidity. The crossbeam is a straight-line structure with two mounting slots on the crossbeam, which are marked as a left slot 11 and a right slot 12 according to different positions. The left slot is 20 cm long ( Figure 4 The right slot is 10 cm long (L2 length). Figure 4 The left slot has a short slot hole with a length of about L1, and the two ends of the left slot hole are provided with a positioning slot 13 formed by milling grooves, and the outer end of the right slot hole is provided with a positioning slot 13' formed by milling grooves. The spacing between the positioning slot at the right slot hole and the two positioning slots in the left slot hole is 90 cm ( Figure 4 Middle D length) and 106 cm, that is, the three positioning slots are respectively matched with the left and right adjustment hook rods 20.

[0031] The total length of the adjustment hook rod 20 is designed to be about 140 cm. The outer end of the adjustment hook rod has an L-shaped hook portion 21. Opposite to the hook portion 21 is a clamping portion 22 arranged away from the hook portion. The clamping portion 22 is a multi-gear clamping slot formed by four gears. The distance between each two adjacent gears is designed to be about 10 cm. The method of using the gear is to pass the clamping portion 22 through the above-mentioned left slot hole or right slot hole and rotate 90°. The rotated adjustment hook rod 20 slides along the crossbar and clamps into the above-mentioned positioning slot 13. The mutual limitation of the positioning slot and the clamping slot fixes the adjustment hook rod relative to the crossbeam. Therefore, through the above-mentioned operation, the distance between the hook and the crossbeam can be adjusted. Refer to Figure 1 and Fig. 9 That is to say, the adjusting hook rod 20 is a key component for connecting the side frame of the freight car bogie with the load saddle. By adjusting the different gears of the hook rod, it is suitable for connecting the load saddles of different sizes and models of K2, K4, K5, and K6 bogies with the side frame of the bogie.

[0032] That is, by adjusting the hook rod and cooperating with the positioning slots at different positions on the cross beam, the effectiveness of the hook rod is adjusted, and the spacing between the hook rods is adjusted to meet the lateral and longitudinal dimension adjustment requirements of different load-bearing saddles.

[0033] The above-mentioned adjustment hook rod 20 is composed of two 5mm steel plates, which has stability and durability during operation and is easy to adapt to the width of different side frames of different bogies.

[0034] Support plate 30: The support plate is in the shape of a flat plate and is a support structure. The central part of the support plate is connected to an adjustment rod 40 through a ball joint. The adjustment rod 40 is a threaded rod that is mechanically matched with the threaded hole in the middle of the above-mentioned crossbeam through threaded matching. It is easy to understand that when the adjustment rod 40 is rotated, the distance between the support plate and the above-mentioned crossbeam can be adjusted. It can also be said that by adjusting the above-mentioned adjustment rod, the distance between the support plate and the hook of the adjustment hook rod on both sides can be adjusted, thereby achieving the fixing of the load saddle and the side frame together to ensure that they will not move or fall off during operation.

[0035] Furthermore, a handle 41 is provided at the outer end of the adjusting rod 40, which is also the operating end and is used to operate the adjusting rod, that is, to realize the operation of the adjusting rod.

[0036] Furthermore, a nut 42 is sleeved on the adjusting rod 40, and the position of the adjusting rod can be locked by rotating the nut. After the position is locked, the adjusting rod is locked on the beam and does not have a relative rotation function.

[0037] Here’s how to use the tool:

[0038] When replacing the wheelset of a railway freight car, according to the bogie model, the adjusting hook rod is clamped in the position corresponding to the model mark on the crossbeam structure according to the model mark on the side, so that the distance between the two adjusting hook rods can be adjusted. Then, the hook is slid into the upper part of the side frame from the side position of the bogie side frame, and the end of the hook is aligned with the nose of the load-bearing saddle. The adjusting rod is tightened, and the support plate will be pressed against the upper part of the side frame during the tightening process, so that the wheelset can be quickly replaced.

[0039] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in the field should fall within the scope of protection determined by the claims of the present invention.
