Description

Technical Field

[0001] The present invention relates to the field of rail transit, and in particular to a base for support, a maintenance platform, and a wheel maintenance method. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The wheelset of a train includes two wheels. For the train to run smoothly, the health condition of the wheels cannot be ignored. Therefore, after the wheels are manufactured, they need to be inspected. After the wheels have been used for a long time, they need to be removed and inspected. During the inspection process, problems such as scratches, pits, and out-of-roundness on the wheel surface can be found. After the inspection is completed, the wheels need to be repaired in a timely manner. Since both the two end faces and the circumferential surface of the wheels need to be inspected, the wheels need to be placed vertically for corresponding inspection operations during the inspection process, and also need to be placed horizontally for corresponding inspection operations. The wheels need to be frequently placed vertically and horizontally. The wheels are placed vertically at the corresponding vertical placement positions (such as the wheel storage rack in Chinese Patent Application CN201621297780.1), and horizontally at the corresponding horizontal placement positions. In this way, the wheels need to be hoisted back and forth between the vertical placement position and the horizontal placement position for turnover in order to achieve repeated adjustment. The biggest reason for this is that there is no device in the prior art that can support the wheels vertically and horizontally. The vertical placement device is usually relatively high to prevent the wheels from tilting so that the wheels cannot be placed horizontally. The horizontal placement device is a platform and cannot support the wheels vertically. For the back-and-forth hoisting, complex hoisting mechanisms such as gantry cranes are required, and at the same time, the maintenance operation time is increased.

[0004] In addition, Chinese Patent Application CN201710780082.X discloses a wheel maintenance device, which is for the support device of the wheelset and not for the support of a single wheel. Of course, it also shows that the existing support devices cannot support the wheels or the wheelset. There are support devices for the wheelset and separate support devices for the wheels, and there is no integration.

[0005] Of course, other components also face the problem that it is difficult to integrate vertical placement and horizontal placement during manufacturing and maintenance. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a base for support, which can support the object to be supported vertically and horizontally and meet the support requirements of different states of the object to be supported.

[0007] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0008] In a first aspect, the present invention provides a support base, which includes a support seat. Inside the support seat, several groups of support members are arranged. Each group of support members includes at least one support portion. The support members are arranged along the X direction of the support seat. The side length of the support seat in the X direction is less than the side length or diameter of the object to be supported. A through groove is provided on at least one side of the support seat. The through groove of the support seat and one group of support members are arranged in the same plane. The object to be supported is placed upright through the support members and the through groove. The through groove plays a limiting role for the object to be supported placed upright, or the object to be supported is placed flat through the upper surface of the support seat.

[0009] For the base as described above, support members are arranged inside the support seat, and a through groove is provided on the side of the support seat. The through groove and the support members are arranged in the same plane. In this way, the upright support of the object to be supported can be realized through the support members and the through groove located in the same plane. The support members support the bottom side of the object to be supported, and the through groove plays a limiting role for the object to be supported. The flat support of the object to be supported is realized through the upper surface of the support seat. In this way, integration and unity are achieved to meet the support requirements of the object to be supported.

[0010] For a support base as described above, the support portion is arranged below the upper surface of the support seat to realize the support of the bottom side of the object to be supported and avoid interference when the object to be supported is placed flat.

[0011] For a support base as described above, there are two support portions in one group of support members. The two support portions are arranged at an interval. The support seat is provided with the through grooves on both sides of one group of support members. The distance between the two through grooves on both sides is less than the side length or diameter of the object to be supported. The support seat is hollow below the through groove. The distance between the two support portions in the same plane is less than the distance between the two through grooves on both sides. In this way, the stable support of the object to be supported when placed upright is ensured through the setting of the two support portions and the two through grooves.

[0012] For a support base as described above, the support portion is a support wheel. The support wheel is rotatable relative to the support seat. The central axis of the support wheel is parallel to the side where the through groove is located. Through the support wheel, the object to be supported can be rotated relative to the support seat. For a wheel to be rotated, it can ensure the stability of the object to be supported such as a wheel when placed upright and enable the wheel to rotate along the circumference, effectively improving the maintenance efficiency of the wheel.

[0013] For a support base as described above, the support seat is provided with at least two support members as described above. The upright support of multiple objects to be supported is realized through each support member and the corresponding through groove, or the distance between two support members is adapted to the distance between a pair of objects to be supported to realize the support of the pair of objects to be supported, so that the support of both wheel sets and wheels can be realized by the base at the same time, further broadening the usage requirements of the base.

[0014] A base for support as described above, wherein a stop member is provided at the through groove of the support base. The upper surface of the stop member is flush with the upper surface of the support base. The stop member is movably arranged relative to the support base. When the object to be supported is placed upright, the stop member is placed at the side of the through groove. When the object to be supported is placed flat, the stop member can be placed at the through groove. When the stop member is opened relative to the support base, the upright placement of the object to be supported is ensured. When the object to be supported is placed flat, the stop member is rotated so that the stop member returns to the side of the support base, ensuring the stability when the object to be supported is placed flat.

[0015] A base for support as described above, wherein the stop member is hingedly connected to the support base. The hinge point of the stop member and the support base is located at the side of the support base. The length of the stop member is adapted to the length of the through groove. The side of the stop member away from the hinge point is arc-shaped to avoid interference between the stop member and the support base during the rotation process.

[0016] A base for support as described above, wherein the support base has a set height. The support base is a frame-shaped structural member. A support plate is provided at the inner bottom of the support base. The support plate supports the support member. The support plate is connected to the support base to ensure the setting strength of the support member.

[0017] In a second aspect, the present invention also provides an application of a base for support, which is applied to the maintenance operation of wheels, and meets the requirements for the flat placement and upright placement of wheels through the base for support.

[0018] In a third aspect, the present invention also provides a maintenance platform, including the base for support as described above, and a lifting mechanism is provided above the support base.

[0019] In a fourth aspect, the present invention also provides a method for wheel maintenance, using the base for support as described above, including the following content:

[0020] The support base is supported on the ground;

[0021] The wheel is lifted to the support base through the lifting mechanism. The side of the wheel enters the through groove. The upright placement of the wheel is realized through a set of lifting members and the through groove in the same plane, and the circumferential side surface of the upright-placed wheel is maintained.

[0022] The wheel is lifted by the lifting mechanism, and the wheel is supported by the upper surface of the support base to realize the flat placement of the wheel, and one end face of the flat-placed wheel is maintained.

[0023] The wheel is lifted by the lifting mechanism, the wheel is flipped, and the wheel is supported by the upper surface of the support base to realize the flat placement of the wheel, and the other end face of the flat-placed wheel is maintained.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) The base provided by the present invention has a reasonable structural setting. A support member is arranged inside the support base, and a through groove is arranged on the side of the support base. The through groove and the support member are arranged in the same plane. In this way, the vertical placement support of the object to be supported can be realized through the support member and the through groove in the same plane. The support member supports the bottom side of the object to be supported, and the through groove plays a limiting role on the object to be supported. The flat placement support of the object to be supported is realized through the upper surface of the support base. In this way, integration and unity are achieved, meeting the support requirements for the vertical and flat placement of the object to be supported, and there is no need to switch back and forth between multiple support positions.

[0026] 2) In the present invention, the support part is arranged lower than the upper surface of the support base. When the object to be supported is placed vertically, the object to be supported passes through the through groove and the support part supports the bottom side of the object to be supported. The side of the through groove limits the object to be supported, and moreover, it avoids interference problems caused by the support part when the object to be supported is placed flat.

[0027] 3) In the present invention, the base has a reasonable structural setting. A support member is arranged inside the base, and a through groove is arranged on the side of the base. The support base is hollowly arranged below the through groove to avoid interference problems when the object to be supported enters the through groove. The support part is a support wheel, and the support wheel can rotate. For a wheel to be rotated, it can ensure the stability of the object to be supported such as a wheel when placed vertically and enable the wheel to rotate along the circumference, effectively improving the maintenance efficiency of the wheel.

[0028] 4) In the present invention, a stop member is arranged at the through groove of the support base. The upper surface of the stop member is flush with the upper surface of the support base. The stop member is movably connected to the support base. When the stop member is opened relative to the support base, it ensures the vertical placement of the object to be supported. When the object to be supported is placed flat, the stop member is rotated so that the stop member returns to the side of the support base, ensuring the stability when the object to be supported is placed flat.

[0029] 5) In the present invention, a maintenance platform is provided. The maintenance platform includes a base, and a lifting mechanism is arranged above the base. In this way, by using the lifting mechanism to lift the object to be supported such as a wheel, the rapid switching between the vertical and flat placement states of the wheel can be quickly realized, without the need to move between the vertical placement position and the flat placement position. The requirements for the lifting mechanism can be relatively simple, mainly being able to achieve lifting, and there is no need to achieve lateral reciprocating movement.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0040] As introduced in the background art, in the prior art, the support platform can only achieve the vertical or horizontal placement of the supported object. To solve the above technical problems, the present invention proposes a support base.

[0041] Embodiment 1

[0042] In a typical embodiment of the present invention, refer to Figure 1As shown in the figure, a base for support includes a support base 1. Inside the support base 1, several groups of support members 3 are provided. Each group of support members 3 includes at least one support portion 4. The support members 3 are arranged along the X direction of the support base 1. The X direction of the support base 2 refers to the width direction of the support base. The side length of the support base in the X direction is less than the side length or diameter of the object to be supported. Through grooves are provided on at least one side of the support base 1. The through grooves of the support base 1 and one group of support members 3 are arranged in the same plane. The object to be supported is placed upright through the support members 3 and the through grooves. The through grooves play a role in limiting the upright object to be supported, or the object to be supported is placed flat through the upper surface of the support base 1.

[0043] In this embodiment, the support base 1 has a set height. The support base 1 is a frame - type structural member. Refer to Figure 3 As shown in the figure, a support plate 10 is arranged at the inner bottom of the support base 1. The support plate 10 supports the support members 3. The support plate is connected to the support base to ensure the setting strength of the support members 3.

[0044] Specifically, refer to Figure 4 As shown in the figure, the support base 1 includes a bottom frame 8. Multiple vertical beams 6 are arranged on the side of the bottom frame 8. Along the length direction of the bottom frame 8, multiple vertical beams 6 are provided on one side. The adjacent two vertical beams 6 are arranged at an interval. A first cross - beam 7 is arranged along the width direction of the support base 1. There are two first cross - beams 7. The first cross - beams 7 connect two vertical beams 6. A second cross - beam 5 is arranged along the length direction of the support base 1. There are two second cross - beams 5. The second cross - beams 5 connect multiple vertical beams. There is an interval between the second cross - beams 5 and the bottom frame 7. The support plate 10 is arranged in the width direction of the bottom frame 8.

[0045] Refer to Figure 1 、 Figure 2 As shown in the figure, the support base 1 is provided with three support members 3. Corresponding to this, three through grooves are provided at the second cross - beam 5. Through grooves are provided on both second cross - beams 5 on both sides. The position of the through grooves and the corresponding support members 3 are in the same plane. In this way, the upright support of the object to be supported can be realized; in other examples, the support base 1 can also be provided with four or five or other numbers of support members, which can realize the batch support of wheels.

[0046] When the support base 1 is provided with multiple support members 3, the upright support of multiple objects to be supported such as wheels is realized through each support member 3 and the corresponding through grooves. Or the distance between two of the support members 3 is adapted to the distance between the paired objects to be supported (wheel sets composed of wheels). The support of both wheel sets and wheels can be realized through the base at the same time, further broadening the usage requirements of the base. For example, when three support members are provided on the support base, the support of the wheel set is realized through two support members 3 and the corresponding through grooves, and the support of the wheel is realized through the other support member and the corresponding through groove.

[0047] It is easily understood that the supporting part 4 is arranged below the upper surface of the supporting seat 1 to support the bottom side of the object to be supported, so as to avoid interference when the object to be supported is placed flat.

[0048] Refer to Figure 1 As shown, there are two supporting parts 4 in a group of supporting members, and the distance between the two supporting parts 4 is set. The supporting seat 1 is provided with through grooves on both sides of a group of supporting members. The supporting seat 1 is hollow below the through grooves to avoid interference problems when the object to be supported enters the through grooves. The distance between the two supporting parts in the same plane is less than the distance between the through grooves on both sides. In this way, the stable support of the object to be supported when placed upright is ensured through the two supporting parts 4 and the two through grooves.

[0049] In this embodiment, the supporting part 4 is a supporting wheel, and the supporting wheel is rotatable relative to the supporting seat 1. The central axis of the supporting wheel is parallel to the second cross beam 5. Two brackets 11 are arranged on the surface of the supporting plate 10 to support the supporting wheel. Through the supporting wheel, the object to be supported can be rotated relative to the supporting seat 1. For the wheel to be rotated, it can ensure the stability of the object to be supported such as the wheel when placed upright and enable the wheel to rotate along the circumference, effectively improving the maintenance efficiency of the wheel.

[0050] It is easily understood that, refer to Figure 5 As shown, both sides of the supporting wheel are conical, that is, the supporting wheel adopts a structure with a wider outer part and a narrower inner part. The inclined surface position on the inner side of the supporting wheel contacts the edge of the wheel. The central positions on both sides of the supporting wheel are designed with protruding mounting shafts, and the mounting shafts are installed on the two brackets 11 through bearings. The two brackets 11 are vertically fixed at the supporting plate 10, so as to realize the circumferential rotation of the supporting wheel while keeping the bracket stationary; the material of the supporting wheel can be alloy steel to ensure the strength of the supporting wheel.

[0051] Refer to Figure 1 As shown, the supporting seat 1 is provided with a stopper 2 at the through groove. The upper surface of the stopper 2 is in the same plane as the upper surface of the supporting seat 1 to ensure the absolute support for the object to be supported when the stopper 2 is located in the through groove. The stopper 2 is movably arranged relative to the supporting seat 1. When the object to be supported is placed upright, the stopper is placed at the side of the through groove. When the object to be supported is placed flat, the stopper can be placed at the through groove. When the stopper 2 is opened relative to the supporting seat 1, the upright placement of the object to be supported is ensured. When the object to be supported is placed flat, the stopper 2 is rotated so that the stopper 2 returns to the side of the supporting seat 1 to ensure the stability of the object to be supported when placed flat.

[0052] Specifically, the stopper 2 is hingedly connected to the support base 1, and the hinge connection can be achieved through a hinge 9. The stopper rotates 90° along the hinge 9 to open and close. The hinge joint between the stopper 2 and the support base 1 is located on the side of the support base 1. The length of the stopper 2 is adapted to the length of the through groove. The stopper 2 is a stop block. The height of the stopper is the same as the height of the second cross beam 5, and the width of the stopper 2 is the same as the width of the second cross beam 5. The side of the stopper 2 away from the hinge joint is arc-shaped to avoid interference between the stopper and the support base 1 during the rotation of the stopper.

[0053] In some examples, flexible pads are respectively arranged at the two side walls of the through groove of the second cross beam 5. The arrangement of the flexible pads avoids interference between the object to be supported, such as a wheel, and the second cross beam 5. The arrangement of the flexible pads also ensures that after the stopper enters the through groove, it is in close contact with the flexible pads and the second cross beam 5, ensuring the flatness of the stopper 2 and the second cross beam, so as to ensure the accuracy of the maintenance operation.

[0054] The base provided in this embodiment has a reasonable structural arrangement. A support member 3 is arranged inside the support base 1, and a through groove is arranged on the side of the support base. The through groove and the support member are arranged in the same plane. In this way, the vertical placement support of the object to be supported can be realized through the support member 3 and the through groove in the same plane. The support member supports the bottom side of the object to be supported, and the through groove plays a limiting role on the object to be supported. The flat placement support of the object to be supported is realized through the upper surface of the support base, so as to achieve integration and unity; the support wheel can rotate. For a wheel to be rotated, it can ensure the stability of the object to be supported, such as a wheel, when placed vertically and enable the wheel to rotate along the circumference, effectively improving the maintenance efficiency of the wheel; the stopper 2 cooperates with the support base 1 and maintains the same direction. The wheel can be placed flat above the support base to realize the maintenance of the wheel in the flat placement state; if the wheel needs to be placed vertically, open the stopper along the hinge, and the wheel can pass through the through groove at the second cross beam and be placed vertically on the support wheel of the support device, ensuring the stability of the wheel when placed vertically and enabling it to rotate along the circumference.

[0055] Embodiment Two

The hoisting mechanism can be a simple manual hoist or a hand-operated hoist, and only a lifting mechanism needs to be realized, without setting a complex hoisting mechanism.

[0059] Embodiment Four

[0060] This embodiment provides a method for wheel maintenance, which uses a support base described in Embodiment 1 and includes the following content:

[0061] The support base 1 is supported on the ground;
