Description

Technical Field

[0001] The utility model relates to the technical field of large-tonnage rail vehicles, in particular to a large-tonnage steering wheel set. Background Art

[0002] For the transportation of large-tonnage ladles in steel mills, the weight is between 350t and 450t. Adding the weight of the transportation equipment itself, the total weight reaches 400t to 500t. Such large-tonnage transport vehicles are all supported by four groups of balance wheel sets, with two wheels on each balance wheel set, a total of eight wheels to support the movement.

[0003] These large-tonnage transport vehicles are all single-rail straight-running vehicles and cannot turn. The operation of single-rail straight-running vehicles has the problem of low efficiency. There is only one track, and vehicles can only pass in line, seriously affecting production efficiency. Content of the Utility Model

[0004] The utility model provides a large-tonnage steering wheel set to solve the problems in related technologies. This device solves the problems of inability to turn and low production efficiency.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A large-tonnage steering wheel set of the utility model includes two wheel sets arranged in parallel side by side. A balance beam is arranged between the wheel sets. The balance beam is a hollow square body. The wheel boxes of the wheel sets extend into the balance beam. Vertical swing pins are arranged on the balance beam and the wheel boxes. The swing pins penetrate the balance beam and the wheel boxes, so that the wheel sets are rotatably connected to the balance beam. A support structure is arranged above the balance beam. The balance beam and the support structure are connected through a connecting seat. A balance pin is arranged on the connecting seat. The balance pin penetrates the connecting seat and the balance beam.

[0007] The wheel sets, the balance beam and the swing pins form an integral body.

[0008] In the above solution, when the rail is uneven, the wheel sets can swing slightly up and down with the balance pin as the rotation fulcrum. When the wheel sets drive into the turning rail, the wheel rims of the wheel sets are squeezed by the rail, and there is a horizontal axial thrust. Under the action of the thrust, the wheel sets rotate along the swing pins, so as to realize the turning of the wheel sets, thus solving the problem of inability to turn and greatly improving production efficiency.

[0009] The support structure includes a slewing bearing. The slewing bearing is fixedly connected to the connecting seat. A fixing plate for connecting with the vehicle body is fixedly connected to the slewing bearing.

[0010] In the above solution, through the setting of the support structure, the gravity of the vehicle body is transmitted to the slewing bearing, the slewing bearing then transmits the gravity to the connecting seat, the connecting seat transmits it to the balance pin shaft, the balance pin shaft transmits it to the balance beam, the balance beam transmits it to the rotating part and the swing pin shaft, and finally the gravity is transmitted to the wheel set.

[0011] Convex blocks are fixedly connected to both sides of the wheel set. A hole is provided on the convex block, and a tension spring is provided on the hole. One end of the tension spring is fixedly connected to the convex block, and the other end of the tension spring is fixedly connected to the balance beam.

[0012] In the above solution, through the setting of the tension spring, when the tension spring is installed, it is in a pre-stretched state, and there is an equal pulling force on both sides, which can forcibly ensure that the wheel set does not deflect and is guaranteed to be in the middle position.

[0013] A rotating part is provided between the wheel box and the balance beam.

[0014] In the above solution, through the setting of the rotating part, it is used to reduce friction and improve mechanical efficiency.

[0015] The wheel set drives the vehicle body to move along the direction of the rail.

[0016] Adopting the above solution, there are the following specific advantages:

[0017] 1. Since a large-tonnage steering wheel set of the present utility model includes two wheel sets arranged in parallel side by side, a balance beam is provided between the wheel sets. The balance beam is a hollow square body. The wheel box of the wheel set extends into the balance beam. Vertical swing pin shafts are provided on the balance beam and the wheel box. The swing pin shafts penetrate the balance beam and the wheel box, so that the wheel set is rotatably connected to the balance beam. A support structure is provided above the balance beam. The balance beam and the support structure are connected through a connecting seat. A balance pin shaft is provided on the connecting seat. The balance pin shaft penetrates the connecting seat and the balance beam. When the rail is uneven in height, the wheel set can swing slightly up and down with the balance pin shaft as the rotation fulcrum. When the wheel set enters the turning rail, the wheel flange of the wheel set is squeezed by the rail, and there is a horizontal axial thrust. Under the action of the thrust, the wheel set rotates along the swing pin shaft, thereby realizing the turning of the wheel set, greatly improving the production efficiency.

[0018] 2. The support structure includes a slewing bearing, which is fixedly connected to the connecting seat. A fixing plate for connecting to the vehicle body is fixedly connected to the slewing bearing. The gravity of the vehicle body is transmitted to the slewing bearing, and then the slewing bearing transmits the gravity to the connecting seat, the connecting seat transmits it to the balance pin shaft, the balance pin shaft transmits it to the balance beam, the balance beam transmits it to the rotating member and the swing pin shaft, and finally the gravity is transmitted to the wheel set. One end of the tension spring is fixedly connected to the protruding block, and the other end of the tension spring is fixedly connected to the balance beam. Through the setting of the tension spring, the tension spring is in a pre-stretched state during installation, and there is an equal tension on both sides, which can forcibly ensure that the wheel set does not deflect and is guaranteed to be in the middle position. A rotating member is arranged between the wheel box and the balance beam to reduce friction and improve mechanical efficiency. Description of the Drawings

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] In a specific Embodiment 1, as Figures 1 to 5As shown in the figure, a large-tonnage steering wheel set of the present utility model includes two wheel sets 1 arranged in parallel side by side. A balance beam 2 is provided between the wheel sets 1. The balance beam 2 is a hollow square body. The wheel box 101 of the wheel set 1 extends into the interior of the balance beam 2. A vertically arranged swing pin shaft 3 is provided on the balance beam 2 and the wheel box 101. The swing pin shaft 3 penetrates through the balance beam 2 and the wheel box 101, so that the wheel set 1 and the balance beam 2 are rotatably connected. A support structure is provided above the balance beam 2. The balance beam 2 and the support structure are connected by a connecting seat 4. A balance pin shaft 5 is provided on the connecting seat 4. The balance pin shaft 5 penetrates through the connecting seat 4 and the balance beam 2. The wheel set 1 drives the vehicle body to move along the direction of the rail 10. The wheel set 1, the balance beam 2 and the swing pin shaft 3 form an integral body. When the rail 10 is uneven in height, the wheel set 1 can swing slightly up and down with the balance pin shaft 5 as the rotation fulcrum. When the wheel set 1 enters the turning rail 10, the wheel flange of the wheel set 1 is squeezed by the rail 10, and there is a horizontal axial thrust. Under the action of the thrust, the wheel set 1 rotates along the swing pin shaft 3, thereby realizing the turning of the wheel set 1, greatly improving the production efficiency.

[0027] The support structure includes a slewing bearing 6. The slewing bearing 6 is fixedly connected to the connecting seat 4. A fixing plate 7 for connecting with the vehicle body is fixedly connected to the slewing bearing 6. The gravity of the vehicle body is transmitted to the slewing bearing 6, and the slewing bearing 6 then transmits the gravity to the connecting seat 4. The connecting seat 4 transmits it to the balance pin shaft 5. The balance pin shaft 5 transmits it to the balance beam 2. The balance beam 2 transmits it to the rotating member 9 and the swing pin shaft 3, and finally transmits the gravity to the wheel set 1.

[0028] Convex blocks 102 are fixedly connected to both sides of the wheel set 1. A hole is provided on the convex block 102. A tension spring 8 is provided on the hole. One end of the tension spring 8 is fixedly connected to the convex block 102, and the other end of the tension spring 8 is fixedly connected to the balance beam 2. Through the setting of the tension spring 8, there is a tension spring 8 on each side of the wheel set 1. When the tension spring 8 is installed, it is in a pre-stretched state, and there is an equal tension on both sides, which can forcibly ensure that the wheel set 1 does not deflect and is guaranteed to be in the middle position.

[0029] A rotating member 9 is provided between the wheel box 101 and the balance beam 2. In this specific embodiment, the rotating member 9 is a bearing. The inner wall surface of the bearing abuts against the outer wall surface of the swing pin shaft 3 to reduce friction and improve mechanical efficiency.

[0030] As Figure 4 shown, when the rail 10 is uneven in height and there is a height difference H, the wheel set 1 can swing slightly up and down with the balance pin shaft 5 as the rotation fulcrum, so as to realize the smooth operation of the wheel set 1.

[0031] As Figure 5As shown in the figure, when the wheel set 1 travels into the turning rail 10, the flange of the wheel set 1 will be squeezed by the rail 10, and there is a horizontal axial thrust F. Under the action of the thrust F, the tension of the tension spring 8 is overcome, so that the wheel set 1 rotates along the swing pin shaft 3, thus realizing the turning of the wheel set 1.

[0032] In a specific Embodiment 2, the difference between this embodiment and Embodiment 1 is that the rotating member 9 in this embodiment includes a copper sleeve and a copper plate. The lower surface of the copper plate abuts against the upper surface of the copper sleeve, and the inner wall surface of the copper sleeve abuts against the outer wall surface of the swing pin shaft 3.
