Description

Technical Field

[0001] The utility model relates to the field of rail transit disassembly and assembly tools, in particular to a tunnel top plate disassembly and assembly auxiliary tool. Background Art

[0002] The rail transit vehicle gangway is a flexible and movable part of the train, which allows two adjacent carriages to move relative to each other and provides passengers with a safe and comfortable passage. It provides safe standing and passing space for passengers between two adjacent carriages, reduces external noise and heat transfer, and plays a sealing role. The top plate of the gangway is an important part of the gangway, providing the top of the gangway with recoverable deformation ability and sealing effect when passing through a curve, and must be relatively silent when deforming.

[0003] The existing semi-automatic couplers of rail transit vehicles in my country basically need to be fully maintained once a year. At this time, the two-unit train needs to be disassembled and the gangway needs to be dismantled. The disassembly and assembly of the gangway is relatively laborious, and the removal and installation of the top guard plate is particularly laborious, which seriously affects the work efficiency. The space is very narrow and there are safety hazards. After analyzing the reasons for the difficulties, it was found that in addition to the narrow space, the main reason for the difficulty in disassembly and assembly is that the hinge structure of the single top plate and the double top plate in the gangway top plate is an L-shaped slot structure, see Figure 1 The tunnel top plate 1 is hung at the installation position through the L-shaped slot 2. However, since the single top plate and the double top plate are installed facing each other during installation, the movement direction is opposite when removing, and one side of the single top plate is partially inserted into the double top plate after installation. In order to reduce noise, felt is added to the double-layer plate, which makes it very difficult for the double top plate to move horizontally relative to each other. The L-shaped slot structure of the single and double top plates is in opposite directions when removing, which requires greater force and accurate force direction, so there is a problem of difficulty in disassembly and assembly.

[0026] The following is combined with Figure 2-3 This application is described in further detail.

[0027] The embodiments of the present application disclose a tool for assisting in disassembling and assembling a tunnel top plate.

[0028] Auxiliary tools for disassembly and assembly of gangway roof, such as Figure 2 As shown, it includes a base frame 3, a pushing rod 4 and a lifting rod 5. The base frame 3 is in the shape of a long rod and is fixedly installed in the required position. The base frame 3 is provided with a hinge seat 6 which is detachably connected to it. The hinge seat 6 has two hinge seats which correspond to the pushing rod 4 and the lifting rod 5 respectively. The middle parts of the pushing rod 4 and the lifting rod 5 are hinged on the hinge seat 6 and can rotate. The top end of the pushing rod 4 is provided with a rod head 7 for horizontally pushing the top plate 1 of the through channel. The bottom end of the pushing rod 4 is a handheld operating end 8. The top end of the lifting rod 5 has an abutting portion 9 for abutting the bottom wall of the top plate 1 of the through channel. The bottom end of the lifting rod 5 is a handheld operating end 8. The handheld operating end 8 at the bottom is held by hand so that the lifting rod 5 can be rotated to push the top plate 1 of the through channel to rise and fall.

[0029] like Figure 2 As shown, a plurality of first hinge holes 10 for hinged connection with the hinge seat 6 are provided in the middle of the pushing rod 4 and the lifting rod 5. The hinge can be realized by inserting the hinge shaft into the first hinge hole 10. The first hinge holes 10 are arranged at intervals along the length direction of the pushing rod 4 and the lifting rod 5. In this way, in actual use, suitable first hinge holes 10 can be selected for use to achieve the use effect of different lengths of force arms, which has better applicability.

[0030] like Figure 2 and Figure 3As shown, the rod head 7 is L-shaped and one end of it is horizontally arranged and hinged to the top end of the push rod 4, and the other end is vertically arranged and has a pushing portion 11 for abutting the bottom wall of the through-channel top plate 1. The rod head 7 has at least two second hinge holes 12, and the second hinge holes 12 are horizontally spaced. The rod head 7 is hinged to the end of the push rod 4 with the help of the second hinge holes 12. In practice, a suitable second hinge hole 12 can also be selected for use according to the needs of use; in addition, a rubber pad 13 is fixed to the surface of the side of the pushing portion 11 facing the through-channel top plate 1, and the through-channel top plate 1 is in contact with the rubber pad 13, so as to effectively protect the through-channel top plate 1 from damage.

[0031] like Figure 2 As shown, the abutment portion 9 at the top of the lifting rod 5 is provided with a roller 14 rotatably connected thereto, two rollers 14 are symmetrically arranged and the top ends thereof are used to abut against the bottom wall of the through-channel top plate 1. The contact between the rollers 14 and the through-channel top plate 1 facilitates the relative movement of the top end of the lifting rod 5 and the through-channel top plate 1, thereby reducing the surface damage of the through-channel top plate 1 and making the rotation of the lifting rod 5 smoother, thereby effectively reducing the friction resistance.

[0032] like Figure 2 and Figure 4 As shown, the articulated seat 6 includes a seat body 15 and a mounting strip 16. The seat body 15 and the mounting strip 16 are vertically arranged, the seat body 15 is vertically arranged, and the mounting strip 16 is horizontally arranged. The bottom of the seat body 15 has a downward socket 17, and the socket 17 is used to plug and cooperate with the base frame 3. With the help of the socket 17 on the seat body 15 and the base frame 3, the articulated seat 6 can be hung on the base frame 3 as a whole, which effectively improves the convenience of assembly and disassembly, and the articulated seat 6 can be moved horizontally along the length direction of the base frame 3 to adjust the position, which can better meet the good use of various actual working conditions; the mounting strip 16 is used for the push rod 4 and the lifting rod 5 to be hinged, and the mounting strip 16 is one-to-one arranged with the push rod 4 and the lifting rod 5, and the length of the mounting strip 16 corresponding to the push rod 4 is less than the length of the mounting strip 16 corresponding to the lifting rod 5, so that in actual use, the top abutment position of the lifting rod 5 is closer to the middle of the through-channel top plate 1, which improves the stability of use.

[0033] The working principle of the embodiment of the present application is: first rotate the lifting rod 5 so that its top end pushes the through-channel top plate 1 to move upward and lift, then rotate the pushing rod 4 to push the top plate to move horizontally, and finally rotate the lifting rod 5 to further lift the through-channel top plate 1, so that the L-shaped slot 2 on the through-channel top plate 1 can be disengaged, and the disassembly operation is completed.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
