Abstract
Description
Technical Field
[0001] The utility model relates to a support device, in particular to a special support device for a subway car body underframe. Background Art
[0002] During the production of a subway car body underframe, a stable special support is required to support the subway car body underframe, so that the remaining operations can be carried out after the subway car body underframe is placed on it. In addition, different subway car body underframes have different widths, and a special support with adjustable width is required to adapt to subway car body underframes with different widths. Moreover, when the subway car body underframe is hoisted and placed on the special support frame, if there is no guiding device, it is easy to place the subway car body underframe off-center, causing damage to the components on the subway car body underframe, increasing the workload and reducing the work efficiency. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is: how to change the width of the special support to adapt to subway car body underframes with different widths and how to smoothly hoist the subway car body underframe onto the special support in the prior art.
[0004] To solve the above technical problem, a technical solution provided by the utility model is:
[0005] A special support device for a subway car body underframe includes a support frame. At both ends of the upper end surface of the support frame, support bases are arranged, and a middle support is arranged at the middle position. An edge support and a guiding frame are arranged on the support base.
[0006] Further, two guiding frames are arranged, which are respectively arranged on the corresponding support bases. On the same support base, the guiding frame and the edge support are arranged side by side on the support base, and the guiding frame is arranged outside the edge support.
[0007] Further, the guiding frame includes a support column and a guiding block. The guiding block is arranged on the upper end surface of the support column, and the lower end surface is arranged on the support base. One end of the guiding block facing the edge support is set as an inclined surface, and the upper end surface of the edge support is not higher than the lower end surface of the guiding block. When the subway car body underframe is hoisted and transported to the edge support, the subway car body underframe can fall onto the edge support along the inclined surface on the guiding block, playing a role of guiding and preventing inclination.
[0008] Further, the support frame includes a cross beam, a reinforcing beam, and two A-shaped brackets. The two A-shaped brackets are arranged at both ends of the lower end surface of the cross beam to support the cross beam. The A-shaped bracket has a stable structure and can ensure the stability of the entire support. Steel plates with mounting holes are provided at the bottom ends of the two A-shaped brackets and can be fixed to the ground. The middle positions of the two A-shaped brackets are connected together by the reinforcing beam, which can increase the stability of the support device and prevent the support from tipping over.
[0009] Further, a connecting plate is respectively arranged at the left and right ends of the upper end surface of the cross beam. Two rows of first screw holes are arranged along the length direction of the cross beam on each connecting plate, and the two rows of first screw holes are evenly and symmetrically arranged. A pin hole is arranged at the position corresponding to the middle support on the cross beam to facilitate the fixation of the middle support.
[0010] Further, two support bases are provided. The two support bases and the two connecting plates are arranged in one-to-one correspondence. Long circular holes are arranged on each support base in the direction corresponding to the first screw holes. Bolts are used to fix the support base to the connecting plate through the long circular holes and the first screw holes.
[0011] Further, by cooperating and fixing the long circular holes with different first screw holes, the movement of the support base in the length direction of the cross beam can be realized, and then the support base can be fixed at different positions, so that the distance between the two support bases can be adjusted.
[0012] Further, an edge support is arranged on each support base. As the distance between the two support bases can be adjusted, the distance between the two edge supports also changes with the position of the support base, so that the subway underframe with different widths can be supported, and the applicable range is wide.
[0013] Further, first nylon blocks are arranged on the upper end surfaces of the two edge supports to prevent scratches when the subway underframe contacts the support device.
[0014] Further, the guide frames and the edge supports on the two support bases are symmetrically placed.
[0015] Further, second nylon blocks are arranged on the inclined surface to prevent scratches when the subway underframe contacts the guide block.
[0016] Further, the middle support includes at least two third nylon blocks. A pin hole is arranged at the position corresponding to the middle support on the cross beam. Each two third nylon blocks and the lowermost third nylon block and the cross beam are fixedly connected together by positioning pins.
[0017] Further, according to the different heights of the subway car body, third nylon blocks with different heights are used to support the middle part of the subway car body. Positioning pins are designed between the third nylon blocks, and third nylon blocks with different thicknesses are used for cooperation to ensure close contact of the support at the middle position and prevent scratches when the subway car body contacts the middle support.
[0018] The beneficial effects of the present utility model are as follows:
[0019] 1. The two side supports in the present utility model can change with the position changes of the corresponding two support bases, realizing adjustable distance between the two side supports, so as to support subway car bodies with different widths, and having a wide range of applications.
[0020] 2. Guide frames are provided on both of the two support bases in the present utility model. When the subway car body is hoisted and transported to the side support, the subway car body can fall onto the side support along the inclined plane of the guide block on the guide frame, playing a role in guiding and preventing tilting.
[0021] 3. Middle support nylon blocks are provided at the middle position of the cross beam in the present utility model. The height of the middle support can be adjusted at any time according to the height of the subway car body to support the middle part of the subway car body. Positioning pins are designed between the third nylon blocks, and third nylon blocks with different thicknesses are used for cooperation to ensure close contact of the support at the middle position.

[0040] According to the different heights of the subway underframe 15, third nylon blocks 13 with different heights are used to support the middle part of the subway underframe 15. The positioning pins 14 are designed between the third nylon blocks 13, and third nylon blocks 13 with different thicknesses are used for matching to ensure close support at the middle position and prevent scratches when the subway underframe 15 contacts the middle support.
[0041] The process of using the overall technical solution formed by integrating the above embodiments is as follows: Adjust the distance between the two side supports 10 according to the width of the subway underframe 15 to be placed: Calculate the width of the subway underframe 15, symmetrically move the support bases at both ends. After moving to the corresponding positions, use the bolts 9 to fix the support bases 7 on the connecting plate 6 through the oblong holes 8 and the first screw holes 5. As the support bases 7 move, the side supports 10 and the guide frames 11 on the support bases 7 move with the support bases 7. After fixing the support bases 7, select the corresponding third nylon blocks 13 according to the height of the subway underframe 15 for assembly, and form the middle support fixed in the middle of the cross beam 1. Subsequently, hoist the subway underframe 15 onto this special support. When hoisting, when the two ends of the subway underframe 15 are hoisted onto the two corresponding side supports 10, let the subway underframe 15 fall onto the side supports 10 along the inclined surface of the guide blocks 11-2.
