Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of a connection structure between a gantry frame and a corner shed support frame in a passenger car articulated shed, and particularly relates to a passenger car articulated shed connection structure. Background Art
[0002] like Figure 1-4 The figure shows a connection scheme commonly used in the prior art, which connects the gantry frame A and the corner shed support frame B through support blocks 0-1, and then fixes the gantry frame A and the corner shed support frame B together through bolts, thereby achieving the fixation of the relative position between the gantry frame A and the corner shed support frame B.
[0003] like Figure 1-2 As shown, the existing connection scheme includes a gantry frame A, a corner shed support frame B, a support block 0-1 and a cutting bolt 0-2. A fixing bolt (not shown) is passed through the first hole 0-11 to achieve a fixed connection between the upper part of the support block 0-1 and the gantry frame A, and then the cutting bolt 0-2 is passed through the second hole 0-12 to achieve a fixed connection between the support block 0-1 and the corner shed support frame B. Thus, the relative position between the gantry frame A and the corner shed support frame B is fixed by passing the fixing bolt (not shown) and the cutting bolt 0-2 through the support block 0-1 respectively.
[0004] The defects of this connection solution are:
[0005] 1) The first and second holes are close to the connection between the gantry frame A and the corner shed support frame B, which affects the connection strength between the corner shed support frame and the gantry frame, making it prone to breakage.
[0006] 2) If Figure 3-4 As shown, the angles between the gantry frame A and the corner shed support frame B in different bus models are diverse, requiring support blocks of different structures to achieve support. However, the existing support block structure is single and cannot be adapted to all models.
[0007] Therefore, it is urgent to propose a new solution to solve the defects and shortcomings in the above-mentioned prior art. Utility Model Content
[0008] In order to solve the defects and shortcomings in the prior art, the utility model provides a passenger car articulated shed connection structure.
[0009] The technical solutions provided by this utility model are as follows:
[0010] A passenger car articulated shed connection structure includes a first support block fixedly connected to a gantry frame and a second support block fixedly connected to a corner shed support frame, and is characterized in that the first support block and the second support block are hinged via a pin shaft, and a limiting bolt is installed on the pin shaft.
[0011] As a further preferred embodiment of the present invention, a plurality of first mounting holes are defined inside the first support block.
[0012] As a further preferred embodiment of the present invention, the axial direction of the first mounting hole is parallel to the thickness direction of the first support block, and a plurality of first mounting holes are evenly arranged at equal intervals along the extension direction of the first support block.
[0013] As a further preferred embodiment of the present invention, the first bolt passes through the first mounting hole to achieve a fixed connection between the first support block and the gantry frame.
[0014] As a further preferred embodiment of the present invention, auxiliary grooves extending along the width direction of the first support block are further formed on both sides of each of the first mounting holes.
[0015] As a further preferred embodiment of the present invention, a plurality of second mounting holes are provided inside the second supporting block.
[0016] As a further preferred embodiment of the present invention, the axial direction of the second mounting hole is parallel to the width direction of the second support block, and a plurality of second mounting holes are evenly arranged at equal intervals along the extension direction of the second support block.
[0017] As a further preferred embodiment of the present invention, a notch is provided on a side of the second mounting hole away from the corner shed support frame, and the aperture of the notch is smaller than the inner diameter of the second mounting hole.
[0018] As a further preferred embodiment of the present invention, both sides of the notch are configured as inverted cone structures that gradually approach each other from the outside to the inside.
[0019] As a further preferred embodiment of the present invention, a second bolt passes through the second mounting hole to achieve a fixed connection between the second support block and the corner shed support frame, and the second bolt is a cutting bolt.
[0020] Compared with the prior art, the beneficial effects achieved by the present invention include:
[0021] 1) The utility model provides a passenger car articulated shed connection structure, in which a pin is provided between a first support block and a second support block, and a support block with a hinged structure is adopted. The angle between the first support block and the second support block can be adjusted by the pin, which makes it more widely applicable and can adapt to the angles between the support frame of the shed with different corners and the gantry frame, effectively increasing the scope of application.
[0022] 2) The utility model provides a passenger car articulated shed connection structure, which uses multiple cutting bolts to achieve the fixation between the second support block and the corner shed support frame. The fixing effect is stable and not easy to loosen. At the same time, the second mounting hole is far away from the connection position between the gantry frame A and the corner shed support frame B, which has higher strength, is not easy to break, and has higher safety.
[0023] 3) The utility model provides a passenger car articulated shed connection structure, which enhances the strength of the connection position between the gantry frame A and the corner shed support frame B, effectively reduces the risk of damage and lowers maintenance costs.

[0033] [First embodiment]
[0034] like Figure 5 The figure shows a passenger car articulated shed connection structure provided by the first embodiment of the present invention, including a first support block 1 fixedly connected to the gantry frame A and a second support block 2 fixedly connected to the corner shed support frame B. The improvement of this embodiment compared to the prior art is that the first support block 1 and the second support block 2 are hinged by a pin shaft 3. By providing a pin shaft between the first support block and the second support block, a support block with a hinged structure can adjust the angle between the first support block and the second support block by the pin shaft, which has a wider application range and can adapt to different angles between the corner shed support frame and the gantry frame, effectively increasing the scope of application. In order to achieve angle limitation between the first support block and the second support block, a limiting bolt (not shown) is installed on the pin shaft 3.
[0035] like Figure 5 As shown, a plurality of first mounting holes 11 are opened inside the first support block 1 , and first bolts (not shown) pass through the first mounting holes 11 to achieve a fixed connection between the first support block 1 and the gantry frame A.
[0036] In this embodiment, the axial direction of the first mounting hole 11 is parallel to the thickness direction of the first support block 1, and a plurality of first mounting holes 11 are evenly arranged at equal intervals along the extension direction of the first support block 1. While improving the connection strength, the first bolt (not shown) is kept as far away from the connection position between the gantry frame A and the corner shed support frame B as possible, thereby enhancing the strength of the connection position between the gantry frame A and the corner shed support frame B, effectively reducing the risk of damage, and reducing maintenance costs.
[0037] In addition, auxiliary grooves 12 extending along the width direction of the first support block 1 are provided on both sides of each first mounting hole 11. The auxiliary grooves 12 facilitate the position positioning when the first mounting hole 11 is opened on the first support block 1 and the position positioning when the first support block 1 is fixed on the gantry frame A.
[0038] like Figure 5 As shown, a plurality of second mounting holes 21 are opened inside the second support block 2, and the second bolts 4 pass through the second mounting holes 21 to achieve a fixed connection between the second support block 2 and the corner shed support frame B, and the second bolts 4 are cutting bolts.
[0039] In this embodiment, the axial direction of the second mounting holes 21 is parallel to the width of the second support block 2. Multiple second mounting holes 21 are evenly spaced along the extension direction of the second support block 2. This positions the second bolts 4 as far away from the connection between the gantry frame A and the corner shed support frame B as possible. This strengthens the connection between the gantry frame A and the corner shed support frame B, effectively reducing the risk of damage and lowering maintenance costs. Furthermore, the axial directions of the first and second bolts can be oriented in different directions, further enhancing the connection stability between the gantry frame A and the corner shed support frame B in multiple dimensions. Furthermore, the different extension directions of the first and second mounting holes can also facilitate the directional positioning accuracy of the connection structure during actual installation.
[0040] In this embodiment, a notch 22 is defined on the side of the second mounting hole 21 facing away from the corner scaffolding support frame B. The diameter of this notch 22 is smaller than the inner diameter of the second mounting hole 21. This ensures the stability of the second bolt's position within the second mounting hole 21 and prevents the second bolt from accidentally falling out of the notch 22. Furthermore, the sides of the notch 22 are formed with inverted tapered structures 23 that gradually converge from the outside to the inside to prevent large particles of dust and other impurities from accidentally entering the second mounting hole 21.
[0041] like Figure 6 As shown, when installing the connection structure with the hinged support block, the first support block 1 is aligned with the gantry frame A, and the first support block 1 is fixed to the gantry frame A by passing a first bolt through a first mounting hole 11. The second support block 2 is rotated by a pin 3 so that it is parallel to the top beam of the corner shed support frame B. The second support block 2 is then fixed to the corner shed support frame B by passing a second bolt 4 through a second mounting hole 21, thereby achieving the fixation between the corner shed support frame B and the gantry frame A. By providing a pin between the first and second support blocks, the hinged support block can adjust the angle between the first and second support blocks via the pin, which makes it more widely applicable and can adapt to different angles between the corner shed support frame and the gantry frame, effectively expanding its scope of application.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
