[0002] Wheelsets are the parts of a locomotive vehicle that are in contact with the rails. They consist of two left and right wheels firmly pressed onto the same axle. Its main functions include: ensuring the running and steering of the locomotive vehicle on the rails, bearing all static and dynamic loads from the locomotive vehicle and transferring them to the rails, and transferring the loads caused by uneven lines to the various parts of the locomotive vehicle. The driving and braking of the locomotive vehicle are also effected by the wheelset. In order to ensure the smooth operation of the locomotive vehicle and reduce the wheel-rail interaction force and running resistance, the machining ovality and eccentricity of the axle journal and wheel tread, as well as the journal taper, shall not exceed the specified limits.

[0003] When replacing wheelsets on site on a daily basis, the bogie needs to be pushed out before replacing the wheelsets, which increases the time required for replacing the wheelsets.

[0004] Therefore, a wheel pair chain that is easy to use is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an easy-to-use wheelset chain, which has the advantage of reducing the time for wheelset replacement and solves the problem of increasing the time required for wheelset replacement after the bogie is pushed out during daily on-site wheelset replacement.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a convenient-to-use wheelset chain, comprising a bogie, wherein an adjustment mechanism is provided outside the bogie;

[0007] The adjustment mechanism includes a storage box fixedly mounted on the front surface of the bogie, a limit chain installed in the storage box, a limit plate fixedly mounted on the outer peripheral wall of the bogie, a limit hole opened in the limit plate, a movable mechanism arranged outside the bogie, and a moving mechanism arranged outside the bogie;

[0008] The movable mechanism includes a connecting rod fixedly installed on the lower surface of the bogie, a limit box installed on the outer peripheral wall of the connecting rod, a first mounting plate fixedly installed on the lower surface of the limit box, an adjustment box fixedly installed on the upper surface of the first mounting plate, a motor fixedly installed in the adjustment box, a turntable fixedly installed on the output end of the motor and an adjustment rod fixedly installed on the outer peripheral wall of the turntable.

[0011] Furthermore, the upper surface of the first mounting plate is fixedly connected to the fixed adjustment box, and the rotating disk is eccentrically connected to the adjustment rod.

[0012] Furthermore, a buckle is fixedly connected to the outer peripheral wall of the limit chain, and a cover plate is hinged on the upper surface of the limit box.

[0013] Furthermore, the adjusting rod is fixedly connected to the connecting rod, and the buckle is matched with the limiting hole.

[0014] Compared with the prior art, the utility model provides a wheel chain that is easy to use and has the following beneficial effects:

[0015] 1. The easy-to-use wheelset chain can drive the turntable to rotate by setting a motor. After the turntable rotates, it can drive the adjusting rod to rotate around the turntable. The rotation of the adjusting rod drives the connecting rod to slide vertically, so that the connecting rod can drive the bogie to move upward when sliding vertically, thereby solving the problem of daily on-site replacement of wheelsets, which requires the bogie to be pushed out before replacing the wheelset, increasing the time required for changing the wheelset.

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1:

[0024] See also Figure 1-4 ,

[0025] A convenient wheelset chain in the present embodiment includes a bogie 1, an adjusting mechanism is provided outside the bogie 1, the adjusting mechanism includes a storage box 2 fixedly mounted on the front surface of the bogie 1, a limiting chain 3 installed in the storage box 2, a limiting plate 4 fixedly mounted on the outer peripheral wall of the bogie 1, a limiting hole 5 opened in the limiting plate 4, a movable mechanism 6 arranged outside the bogie 1 and a moving mechanism 7 arranged outside the bogie 1.

[0026] The movable mechanism 6 includes a connecting rod 61 fixedly mounted on the lower surface of the bogie 1, a limit box 62 mounted on the outer peripheral wall of the connecting rod 61, a first mounting plate 63 fixedly mounted on the lower surface of the limit box 62, an adjustment box 64 fixedly mounted on the upper surface of the first mounting plate 63, a motor 65 fixedly mounted in the adjustment box 64, a turntable 66 fixedly mounted on the output end of the motor 65 and an adjustment rod 67 fixedly mounted on the outer peripheral wall of the turntable 66.

[0027] In this embodiment, the moving mechanism 7 includes a connecting shaft 71 fixedly mounted on the lower surface of the bogie 1 and a wheelset 72 fixedly mounted on the outer peripheral wall of the connecting shaft 71 .

[0028] In this embodiment, the lower surface of the limit box 62 is fixedly connected to the first mounting plate 63, and the connecting rod 61 is slidably connected to the limit box 62. By setting a sliding connection between the connecting rod 61 and the limit box 62, the rotation of the connecting rod 61 driven by the adjusting rod 67 can be converted into up and down sliding, so that the bogie 1 can be driven to move up and down by the up and down sliding of the adjusting rod 67.

[0029] In this embodiment, the upper surface of the first mounting plate 63 is fixedly connected to the fixed adjustment box 64. By fixedly connecting the first mounting plate 63 and the adjustment box 64, it is convenient to limit the adjustment box 64. The turntable 66 and the adjustment rod 67 are eccentrically connected. By setting them as eccentric connections, the coaxiality of the two adjustment rods 67 during rotation can be guaranteed, thereby increasing the stability of movement.

[0030] In this embodiment, a buckle is fixedly connected to the outer wall of the limit chain 3. By fixing the buckle to the outer wall of the limit chain 3, the buckle can be connected to the external limit mechanism, thereby connecting the bogies 1. A cover plate is hinged on the upper surface of the limit box 62.

[0031] It should be noted that a controller is fixedly connected to the upper surface of the bogie 1 , the controller is electrically connected to the motor 65 , and an observation window is provided on the front surface of the storage box 2 .

[0032] Embodiment 2:

[0033] See also Figure 1-4 On the basis of the first embodiment, the adjusting rod 67 is fixedly connected to the connecting rod 61. By fixing the adjusting rod 67 to the connecting rod 61, the bogie 1 can be driven to move by the connecting rod 61, and the buckle is adapted to the limiting hole 5.

[0034] The working principle of the above embodiment is:

[0035] When the user needs to replace the wheelset 72, the user opens the storage box 2, and then the user takes out the limiting chain 3. The user inserts one end of the limiting chain 3 into the limiting hole 5 of the limiting plate 4. Then the user connects the other end of the limiting chain 3 to the external limiting mechanism. Then the user starts the motor 65 through the controller, and the motor 65 drives the turntable 66 to rotate. The rotation of the turntable 66 drives the two adjusting rods 67 to rotate. The rotation of the adjusting rod 67 drives the connecting rod 61 to slide. The connecting rod 61 drives the bogie 1 to move upward. Then the user replaces the wheelset 72, thereby completing the entire operation process.

[0036] The above beneficial effects are:

[0037] By setting up a motor, the turntable can be driven to rotate. After the turntable rotates, the adjusting rod can be driven to rotate around the turntable. The rotation of the adjusting rod drives the connecting rod to slide vertically, so that the connecting rod can drive the bogie to move upward when sliding vertically, thereby solving the problem of daily on-site replacement of wheelsets, which requires the bogie to be pushed out for wheelset replacement, increasing the time required for wheelset replacement. By setting up a limit chain and a storage box, the limit chain can be stored when it is not needed. When the wheelset needs to be replaced, the user first inserts one end of the limit chain through the limit hole, and connects the other end to the external limit mechanism, thereby limiting the bogie.

[0038] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
