Description

Technical Field

[0001] This utility model relates to the field of locomotive manufacturing technology, and in particular to an auxiliary installation device for coupler attachments. Background Technology

[0002] The coupler is a key component for connecting locomotives and rolling stock and transmitting traction and braking forces. The complex operating conditions of trains mean that the movement and state of the coupler are often a composite of several single motion states. The complex motion state of the coupler causes changes in the relative position between the locomotive and rolling stock, which affects the safety and reliability of auxiliary equipment installed at the ends of the locomotive and rolling stock.

[0003] Currently, most locomotives and rolling stock only have essential auxiliary equipment installed at the ends, such as electrical multiple-connection systems, brakes, and air lines. The installation of these auxiliary equipment involves welding mounting brackets directly onto the coupler heads. However, these welded brackets cannot be removed, which can easily damage the coupler during installation and also affects the coupler's maintenance requirements.

[0004] Therefore, there is an urgent need for an auxiliary installation device for coupler attachments to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary installation device for coupler attachments, which can remove the attachments and mounting brackets from the coupler without affecting the coupler maintenance operation, and meets the general installation requirements of the attachments without damaging the coupler.

[0006] To address the aforementioned problems in the existing technology, this utility model adopts the following technical solution:

[0007] An auxiliary installation device for a coupler attachment is installed on a coupler, the coupler having a first groove and a second groove, and a vertical surface connecting the first groove and the second groove, the first groove being higher than the second groove. The auxiliary installation device for the coupler attachment includes:

[0008] The pad includes a first connecting part and a second connecting part, and an intermediate part connecting the first connecting part and the second connecting part.

[0010] As an optional technical solution, the base includes a first fixing part and a second fixing part, and an abutting part connected to the first fixing part and the second fixing part. The first fixing part is connected to the first connecting part and nested around the hook pin hole. The abutting part can fit against the middle part. The second fixing part is connected to the second connecting part.

[0011] As an optional technical solution, the auxiliary installation device of the coupler attachment further includes a first connector, the first fixing part has a first through hole, the first connecting part has a first mounting hole, and the first connector passes through the first through hole and is connected to the first mounting hole.

[0012] As an optional technical solution, the auxiliary installation device of the coupler attachment further includes a second connector, the second fixing part has a second through hole, the second connecting part has a second mounting hole, and the second connector passes through the second through hole and is connected to the second mounting hole.

[0034] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 1 to 3 As shown, this embodiment provides an auxiliary installation device for a coupler attachment. The auxiliary installation device for the coupler attachment includes a pad 1 and a mounting bracket 2. The pad 1 includes a first connecting portion 11 and a second connecting portion 12, and an intermediate portion 13 connected to the first connecting portion 11 and the second connecting portion 12. The first connecting portion 11 is fixedly embedded in a first groove 101, and the end of the first connecting portion 11 is in contact with the periphery of the hook tongue pin hole 200. The second connecting portion 12 is fixedly embedded in a second groove 102, and the intermediate portion 13 can be in contact with a vertical plane. The mounting bracket 2 includes a base 21 and a fixing seat 22. The base 21 is detachably connected to the pad 1 and is nested in the periphery of the hook tongue pin hole 200. The fixing seat 22 is connected to the base 21 and is used to install the attachment 300.

[0036] For example, the coupler 100 has a first groove 101 and a second groove 102, and a vertical surface connecting the first groove 101 and the second groove 102. Along the thickness direction of the coupler 100, the first groove 101 is higher than the second groove 102, forming a stepped structure. An auxiliary installation device for the coupler attachment is installed on the coupler 100. The coupler 100 is made of C-grade steel or E-grade steel and is suitable for couplers of railway mainline locomotive and rolling stock models such as the 100 series, 102 series, and 193 series for locomotives, and the 15 series, 16 series, and 17 series for passenger and freight cars.

[0037] The outer shape of the first connecting part 11 matches the shape of the first groove 101. The first connecting part 11 is fixedly embedded in the first groove 101, and the end of the first connecting part 11 is tightly fitted with the outer contour of the hook tongue pin hole 200. The outer shape of the second connecting part 12 matches the shape of the second groove 102. The second connecting part 12 is fixedly embedded in the second groove 102, which can restrict the horizontal movement of the pad plate. The middle part 13 fits against the vertical surface. The design of the pad plate 1's shape matching the groove of the coupler 100 increases the contact area between the pad plate 1 and the coupler 100 hook head, and can restrict the horizontal movement of the pad plate 1 when the locomotive or rolling stock starts or accelerates.

[0038] The base 21 is nested around the hook tongue pin hole 200, and restricts the horizontal movement of the mounting bracket 2 when the locomotive is in motion. A part of the base 21 fits perfectly with the shape of the pad 1, and the base 21 is detachably connected to the pad 1 by bolts. On the one hand, the connection between the base 21 and the pad 1 securely fixes the fixing seat 22 and the auxiliary equipment 300 installed on the fixing seat 22 to the hook head of the coupler 100. On the other hand, the detachable connection between the base 21 and the pad 1 allows the auxiliary equipment 300 and the mounting bracket 2 to be removed from the coupler 100 during maintenance without affecting the maintenance operation of the coupler 100. Meanwhile, when the auxiliary equipment 300 is changed, the new auxiliary equipment 300 only needs to be installed at the position of the mounting bracket 2 to replace the auxiliary equipment 300. Without damaging the coupler 100, the general installation requirements of the auxiliary equipment 300 at the locomotive and rolling stock end of the existing coupler 100 are met. Therefore, it has no impact on the three-state operation, anti-jump performance, motion trajectory of the coupler 100 after assembly, and operation, maintenance, inspection, repair, and defect handling of the coupler 100.

[0039] Furthermore, referring to Figures 1-3 The base 21 includes a first fixing part 211 and a second fixing part 212, and an abutting part 213 connected to the first fixing part 211 and the second fixing part 212. The first fixing part 211 is connected to the first connecting part 11 and nested around the hook tongue pin hole 200. The abutting part 213 can fit into the middle part 13. The second fixing part 212 is connected to the second connecting part 12.

[0040] The first fixing part 211 is connected to the abutment part 213, and the first fixing part 211 and the second fixing part 212 are arranged parallel to each other. The second fixing part 212 is connected to the abutment part 213. The shape of the first fixing part 211 is completely fitted to the shape of the first connecting part 11, and the end of the first fixing part 211 is extended and nested around the hook tongue pin hole 200 through the opening of the connecting hole, which restricts the horizontal movement that occurs when the locomotive moves. The second fixing part 212 is connected to the second connecting part 12, the abutment part 213 is fitted to the middle part 13, and the shape of the base 21 matches the pad 1, resulting in high installation structure strength.

[0041] Furthermore, referring to Figures 1-3 The auxiliary installation device for the coupler attachment also includes a first connector 3 and a second connector 4. The first fixing part 211 has a first through hole, and the first connecting part 11 has a first mounting hole. The first connector 3 passes through the first through hole and is connected to the first mounting hole. The second fixing part 212 has a second through hole, and the second connecting part 12 has a second mounting hole. The second connector 4 passes through the second through hole and is connected to the second mounting hole.

[0042] The first connecting member 3 and the second connecting member 4 are bolts. The first connecting part 11 and the second connecting part 12 are both fixedly connected to the first connecting part 11 and the second connecting part 12 by bolts, so that the base 21 is stably installed on the hook head of the coupler 100. The base 21 and the fixing seat 22 are welded together. The auxiliary device 300 is fixedly installed on the fixing seat 22 by bolts, so that the auxiliary device 300 can be installed and fixed on the hook head of the coupler 100. By disassembling the first connecting member 3 and the second connecting member 4, the mounting bracket 2 and the auxiliary device 300 can be removed from the pad 1 without affecting the maintenance operation of the coupler 100. At the same time, when the auxiliary device 300 is changed, only the new auxiliary device 300 needs to be installed at the position of the mounting bracket 2 to realize the installation and replacement of the auxiliary device 300. Without damaging the coupler 100, the general installation requirements of the auxiliary device 300 at the locomotive and rolling stock end of the existing coupler 100 are met.

[0043] Furthermore, referring to Figures 1-3 The mounting bracket 2 also includes a first tie plate 23 and a second tie plate 24. The first tie plate 23 protrudes from the fixing base 22 and is perpendicular to the fixing base 22. The first tie plate 23 is fixedly connected to the first fixing part 211. The second tie plate 24 protrudes from the first tie plate 23 and is perpendicular to the first tie plate 23. The second tie plate 24 is fixedly connected to the base 21.

[0044] The first tie plate 23 is formed by bending an extension of the side of the fixed base 22, which improves the support strength of the fixed base 22. After the auxiliary equipment 300 is installed, an overall stress analysis of the mounting bracket 2 is performed. A second tie plate 24 is installed at the weak points of the fixed base 22 and the first tie plate 23. The first tie plate 23 and the second tie plate 24 connect the fixed base 22 and the base 21 and form multiple triangular structures, which enhances the structural stability of the mounting bracket 2 and optimizes the stress state of the entire mounting bracket 2 structure after the auxiliary equipment 300 is installed. Preferably, both the first tie plate 23 and the second tie plate 24 are provided with weight-reducing holes 5 to reduce costs and achieve weight reduction.

[0045] Furthermore, referring to Figures 1-3 The fixed base 22 includes a support part 221 and a mounting part 222. The support part 221 is connected to the base 21. The vertical height of the support part 221 is greater than the maximum horizontal height difference between two adjacent couplers 100 after the couplers 100 are coupled. The mounting part 222 is used to install the auxiliary equipment 300.

[0046] The mounting part 222 is located above the support part 221. The support part 221 supports the auxiliary equipment 300. The height from the top of the support part 221 to the surface of the coupler head of the coupler 100 is 95mm, which is greater than the maximum horizontal height difference of 75mm between two adjacent couplers 100 after the couplers 100 are coupled. This eliminates the influence of the horizontal height difference between adjacent couplers 100 on the installation of the auxiliary equipment 300 when the couplers 100 are coupled.

[0047] Furthermore, referring to Figures 1-3 The pad 1 is fixedly bonded to the first groove 101 and the second groove 102.

[0048] An acrylic structural adhesive with a bonding strength of 20 MPa is used to bond the pad 1 and the groove of the coupler 100. The design of the pad 1's shape matching the groove of the coupler 100 increases the contact area between the pad 1 and the hook head of the coupler 100, resulting in a stronger adhesive force. Furthermore, under dynamic operating conditions, the pad 1, fixedly embedded in the groove of the coupler 100, can only move vertically upwards and horizontally backwards. The adhesive force of the acrylic structural adhesive on the pad 1 and the weight of the mounting bracket 2 restrict the vertical movement of the pad 1. The hook head of the coupler 100 only moves horizontally backwards when the locomotive brakes. At this time, the buffer device of the coupler 100 absorbs most of the impact force and slows down its movement. The connecting hole at the end of the first fixing part 211 nests around the hook tongue pin hole 200, further restricting horizontal movement. Therefore, the adhesive force between the pad 1 and the hook head of the coupler 100 ensures the structural stability.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
