[0026] like Figure 1-4 As shown, this embodiment provides a gearbox wheel set floating positioning conveying and transferring vehicle, including a vehicle body 1, a fixed support mechanism 2 and a floating support mechanism 3.

[0027] The vehicle body 1 includes a vehicle floor panel 14 and a supporting mechanism and a pressing mechanism arranged on the vehicle floor panel 14 .

[0028] The vehicle bottom plate 14 can move in the front-to-back direction (positive and negative directions of the transportation direction). For example, the vehicle bottom plate 14 is slidably arranged on the first linear guide rail 13, the first linear guide rail 13 is laid on the frame base line body 12, the frame base line body 12 and the first linear guide rail 13 are both arranged in the transportation direction, a first driving device is installed on the vehicle bottom plate 14, a rack is installed on the side of the guide rail, a gear is installed at the output end of the first driving device (speed regulating motor, servo motor, hydraulic motor, etc.), and the gear is meshed with the rack, so as to ensure that it can move in the front-to-back direction. Generally, two first linear guide rails 13 are arranged, one on the left and one on the right, so as to improve the stability of the vehicle bottom plate 14 moving thereon.

[0029] The supporting mechanism is a device with a V-shaped supporting block 19 on the top and the V-shaped supporting block 19 can be raised and lowered to ensure that the center heights of the axles of different vehicle models are consistent. For example, the supporting mechanism includes a supporting seat, a servo screw drive device, a V-shaped supporting block 19 and a guide column; the supporting seat is fixed on the vehicle bottom plate 14, a servo screw drive device is fixedly installed on the supporting seat, a V-shaped supporting block 19 is provided on the lifting screw device, and the guide columns are distributed on both sides of the servo screw drive device, the upper end of the guide column is fixed to the lower part of the V-shaped supporting block 19, and the lower end is inserted into the guide hole on the supporting seat.

[0030] The clamping mechanism is a downward pressing device having a clamping block 18 that can move downward, and is used in conjunction with the supporting mechanism to clamp the shaft of the wheel set. For example, the clamping mechanism includes a second linear guide 15, a clamping slide 16, a third linear guide 17, and a clamping block 18; the second linear guide 15 is horizontally laid on the vehicle bottom plate 14 according to the forward and backward directions of the vehicle bottom plate 14, the clamping slide 16 is slidably mounted on the second linear guide 15, the clamping slide 16 and the second linear guide 15 are moved by gear rack drive, the third linear guide 17 is vertically arranged at the front side of the clamping slide 16, the clamping block 18 is in an inverted L shape, the vertical plate of the clamping block 18 is slidably mounted on the third linear guide 17, the clamping block 18 and the third linear guide 17 are moved by gear rack drive, and can also be moved by servo screw drive, and the horizontal plate of the clamping block 18 extends forward on the top of the vertical plate. When clamping is required, the clamping slide 16 slides into place along the second linear guide 15, and the clamping block 18 moves downward to cooperate with the V-shaped support block 19 to clamp the wheelset placed on the V-shaped support block 19. Generally, two second linear guides 15 are provided, one on the left and one on the right, to improve the moving stability of the clamping slide 16; two third linear guides 17 are provided, one on the left and one on the right, to improve the lifting stability of the clamping block 18.

[0031] The technical solution of the vehicle body 1 is prior art, so it will not be described in detail.

[0032] The fixed support mechanism 2 includes a support plate 23, which is arranged on the vehicle floor 14 and is located on the left or right side of the supporting mechanism. The floating support mechanism 3 includes a support slide 35, which is arranged on the vehicle floor 14 and is located on the front side of the support plate 23. The support slide 35 can move in the left and right directions.

[0033] The supporting mechanism and the clamping mechanism are used to fix the wheelset 11 with the gearbox, and the vehicle body 1 is used to transport and transfer the wheelset with the gearbox. After the wheelset with the gearbox is fixed on the vehicle body 1, the auxiliary supporting running wheels 21 installed under the gearbox are supported on the supporting plate 23, thereby achieving fixed positioning of the gearbox and preventing the gearbox from rotating around the axis. During the process of unloading and pressing the wheels, the auxiliary supporting running wheels 21 are supported on the supporting slide 35, and when the axis moves left and right, the gearbox and the auxiliary supporting running wheels 21 are driven to move synchronously left and right, and the supporting slide 35 moves with the gearbox under the friction force of the auxiliary supporting running wheels 21, thereby achieving floating positioning.

[0034] In this embodiment, two supporting mechanisms are provided, and the two supporting mechanisms are fixed on the vehicle bottom plate 14, one on the left and one on the right, and the support plate 23 is located on the left side of the left supporting mechanism. Optionally, the support plate 23 is located on the right side of the right supporting mechanism.

[0035] In this embodiment, the fixed support mechanism 2 further includes a mounting bracket 22, the mounting bracket 22 is fixed on the vehicle floor 14, and the support plate 23 is laid on the mounting bracket 22. The mounting bracket 22 can effectively increase the height of the support plate 23, and does not need to use a too thick plate, so that the support plate 23 can support the auxiliary support running wheel 21 installed under the gear box, thereby reducing the overall weight.

[0036] In this embodiment, the floating support mechanism 3 also includes a base mounting plate 31 and a slide rail 32. The base mounting plate 31 is fixed on the vehicle bottom plate 14. The slide rail 32 is laid on the base mounting plate 31 along the left-right direction. The support slide 35 is slidably arranged on the slide rail 32. With the base mounting plate 31 as the basis for installing the floating support mechanism 3, the floating support mechanism 3 can be made as a whole, which is convenient for modifying the existing transport transfer vehicle without floating positioning. The support slide 35 is slidably arranged on the slide rail 32 to ensure that the support slide 35 moves with the gear box. Generally, two slide rails 32 are provided, one in front and one in the back, to improve the moving stability of the support slide 35.

[0037] In this embodiment, the floating support mechanism 3 also includes a power reset device, which includes a fixed part and a movable part, wherein the fixed part is fixed on the base mounting plate 31, and the movable part is connected to the support slide 35 by transmission. During the process of unloading and pressing the wheel, the gear box drives the support slide 35 to move through the auxiliary support running wheel 21. During the next unloading and pressing, the support slide 35 needs to be reset. By setting the power reset device, the support slide 35 can be reset to ensure that the auxiliary support running wheel 21 is pressed on the support slide 35 before the next unloading and pressing. There are one or more power reset devices, depending on the force to reset the support slide 35. The power reset device in this embodiment is a reset cylinder 33, and there are two reset cylinders 33, which are arranged one on the left and one on the right. The cylinder head 34 of the reset cylinder 33 on the left faces right, and the cylinder head 34 of the reset cylinder 33 on the right faces left. The two cylinder heads 34 are respectively pressed against the slider at the bottom of the support slide 35, so that after the support slide 35 moves left and right, the corresponding cylinder will be compressed. After the support slide 35 loses the force of the auxiliary support running wheel 21 on it, the compressed cylinder pushes the support slide 35 to reset when it resets. Optionally, compressed gas is introduced into the reset cylinder 33 to reset the support slide 35, and the compressed gas pipeline is installed in the drag chain 36.

[0038] In this embodiment, the upper side surface of the support slide 35 is provided with ridges or grooves extending in the front-to-back direction, and the ridges or grooves of the support slide 35 correspond to the grooves or ridges of the auxiliary support running wheels 21, thereby realizing the function of limiting the position when the support slide 35 floats left and right.

[0039] It should be noted that the gearbox does not have an auxiliary support wheel. During the inspection and repair of the wheelset (axle) with a gearbox, it is necessary to install a supporting auxiliary running wheel (also called a walking wheel) on the gearbox. This not only supports the gearbox, but also can passively assist in supporting the gearbox when the wheelset rolls. It is commonly known as the "third leg" support wheel, which is the auxiliary support running wheel 21 mentioned above.

[0040] "Transportation" and "transferring" are two subdivided functional names: when the workpiece is carried into the equipment, the transportation function is presented, which is called the transportation function; when the work is completed in the equipment area, the robot is used for lifting (loading) and unloading. The gearbox wheel set floating positioning transportation and transfer vehicle in this embodiment includes two functions: transportation and transfer.

[0041] During the maintenance process, "loading" and "unloading" with the help of the robot is called "transfer"; the transfer of workpieces from the "loading position" - "working position" - "discharging position" of maintenance equipment such as wheelset press and wheelset disassembly machine is called "conveying".

[0042] After the wheelset is sent into the equipment, the vehicle body 1 is withdrawn, and the gearbox is supported by the floating support mechanism 3 and moves with the gearbox when it needs to move left and right. When unloading and pressing the wheels, the floating support mechanism 3 always supports the auxiliary supporting running wheels 21.
