DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 6 The utility model of the special-shaped transmission roller of the truck center beam comprises a transmission roller 1, a transmission column 2 and a limit column 3. The transmission roller 1 has two outer ends symmetrically rotatably connected with the transmission column 2, and the transmission column 2 has two outer ends symmetrically rotatably connected with the limit column 3. The transmission roller 1, the transmission column 2 and the limit column 3 are connected with grooves 4. There are several grooves 4. The depth of the groove 4 is the same as the height of the bottom surface 5 of the impact seat of the hat-shaped steel center beam or the box-shaped beam protruding from the bottom surface 6 of the steel. For example, the height of the bottom surface 5 of the impact seat protruding from the bottom surface 6 of the steel is 12.5 mm, and the depth of the groove 4 is 12.5 mm.

[0024] Combination Figure 4 The two ends of the limit column 3 are symmetrically rotatably connected to the limit plate 7, the two ends of the limit plate 7 are symmetrically rotatably connected to the mounting seat 8, and the mounting seat 8 on one side is rotatably connected to the transmission member 9. The limit column 3 includes a first slope limit surface 31 and a cylindrical surface 32. The side of the limit plate 7 is provided with a cylindrical surface 32, and the side of the transmission column 2 is provided with a first slope limit surface 31.

[0025] The limiting plate 7 includes a second slope limiting surface 71 and a back slope surface 72 . The back slope surface 72 is disposed on the side of the mounting seat 8 , and the second slope limiting surface 71 is disposed on the side of the cylindrical surface 32 .

[0026] The second slope limiting surface 71 is used to guide and limit the H-shaped steel center beam, which can be guided to slide along the second slope limiting surface 71 to the columnar surface 32. The rotation of the columnar surface 32 drives the H-shaped steel center beam to move. The first slope limiting surface 31 is used to guide and limit the B-shaped steel center beam and the cap-shaped steel center beam. The B-shaped steel center beam and the cap-shaped steel center beam can be guided to slide along the first slope limiting surface 31 to the transmission column 2. The rotation of the transmission column 2 drives the B-shaped steel center beam and the cap-shaped steel center beam to move.

[0027] Combination Figure 6 The cross section of the groove 4 connected to the transmission roller 1, the transmission column 2 and the limit column 3 is "L"-shaped, and the center of the groove 4 is rotationally symmetrically distributed. For example, when the hat-shaped steel C80B encounters the transmission roller 1 during transportation, the protruding part of the bottom surface 5 of the impact seat will enter the groove 4 in advance, and then smoothly transition and move through the groove 4.

[0028] Working principle: Place the hat-shaped steel at the upper end of the device and limit it by the first slope limit surface 31. The transmission member 9 rotates to drive the transmission column 2 to rotate, and drives the hat-shaped steel to move forward. There is an impact seat on the hat-shaped steel, and the bottom surface 5 of the impact seat is lower than the bottom surface 6 of the steel. When the impact seat encounters the device during movement, the protruding part of the bottom surface 5 of the impact seat will enter the groove 4 in advance, and then move through the groove 4 for transition, which can be transmitted smoothly.

[0029] In summary: the utility model of the special-shaped transmission roller for the truck center beam realizes the smooth transmission of the protruding part of the bottom surface of the impact seat when transmitting the hat-shaped steel center beam or box-shaped beam through the several grooves 4 structures opened with rotational symmetry distribution, thus filling the technical gap of the transmission roller transmitting the hat-shaped steel center beam or box-shaped beam and improving the transportation efficiency and transportation quality of railway trucks.
