[0002] Some roof equipment is often installed on the roof of a rail vehicle. A lifting lug is provided on the roof equipment of a conventional rail vehicle, and a connecting hole is provided on the lifting lug. A slide groove is provided on the roof of the rail vehicle. The roof equipment is connected to the roof of the rail vehicle through bolt fasteners. However, since fasteners such as bolts and nuts are often exposed to sunlight and rain, the fasteners are prone to corrosion and need to be replaced frequently. However, when replacing fasteners, the equipment fasteners must be replaced when the equipment is in a lifted state. Therefore, the replacement of fasteners must be equipped with tooling that can lift the equipment, and the replacement process is difficult and complicated.

[0003] In order to solve the above technical problems, the existing Chinese patent publication number CN116061980A is a rail vehicle and roof equipment connection device, installation and disassembly method. On the basis of ensuring that the strength of the equipment mounting seat can meet the vehicle operating conditions, L-shaped long holes are opened on the sides of the equipment lifting ears to ensure that the bolts can slide into the strip holes. At the same time, notches are set in the car body slide grooves between the process holes to ensure that the equipment mounting bolts can slide into the ends of the slide grooves, so that the entire installation and disassembly process no longer relies on lifting the equipment tooling, and the installation and disassembly of the roof equipment can be achieved, which is easy to operate.

[0004] However, the L-shaped long holes provided in the above scheme reduce the structural strength of the components and easily cause deformation of the components. At the same time, the components are still directly exposed to the outside, which is prone to rust and the like, and is not conducive to rapid disassembly, so improvements are needed. Summary of the invention

[0013] Furthermore, during assembly, the rotating shaft and the threaded pipe fitting are coaxially arranged, so as to quickly penetrate the fixing frame and extend into the U-shaped frame assembly. Afterwards, through the cooperation of the resetting mechanism and the extrusion mechanism, the square frame can be quickly rotated to a state perpendicular to the threaded pipe fitting and the second straight tooth condition can be moved in the direction of the first straight tooth condition, so as to quickly engage and fix, effectively limit the position state of the threaded pipe fitting, and achieve the purpose of limiting the relative position between the fixing frame and the U-shaped frame assembly.

[0015] Furthermore, during installation, the insert rod member drives the triangular plate member to descend and abuts against the second straight tooth member so that the second straight tooth member extends out of the square frame member, so that the second straight tooth member and the first straight tooth member are meshed.

[0016] Preferably, the extrusion mechanism includes two fixed rods slidably installed in the threaded tube fitting, a transverse axis member is commonly fixed at one end of the two fixed rods, two return spring members are fixed on one side of the transverse axis member, one end of the two return spring members are fixed on one end side wall of the threaded tube fitting, the insert rod member and the transverse axis member on which the return spring member is installed are in conflict with each other, vertical rod members are fixed on both sides of the lower end of the transverse axis member, the lower ends of the two vertical rod members are rotatably connected with push rod members, the two push rod members are rotatably connected to the two pull rod members respectively, and limiting rods are fixed at the opposite ends of the two fixed plates, and the two pull rod members are in conflict with the two limiting rods respectively.

[0017] Furthermore, when the inserted rod pushes the triangular plate member to descend, it will conflict with the horizontal axis member, causing the horizontal axis member to drive the fixed rod member and the vertical rod member to move, and the push rod member will drive the pull rod member to rotate around the rotating shaft member as the axis. During actual production and preparation, the push rod member adopts an arc structure to facilitate the stable rotation of the rotating shaft member. The pull rod member is fixed by conflicting with the limiting rod member, which can effectively limit the rotation angle of the square frame member and ensure the stable rotation of the square frame member until the threaded pipe fittings are perpendicular to each other.

[0018] Preferably, sliding rods are provided on both sides of the insert rod, the upper ends of the two sliding rods are respectively fixed on both sides of the lower end of the abutment plate, and the lower ends of the two sliding rods are passed through the bottom of the threaded pipe.

[0021] Furthermore, when the threaded pipe fitting cannot move along the direction of the U-shaped frame assembly, the gasket member and the two second hexagonal nut members are installed in sequence corresponding to the threaded pipe fitting located in the fixing frame, which can effectively make the fixing frame and the U-shaped frame assembly fully interfere with each other and improve the firmness of the connection.

[0022] Preferably, the clamping mechanism includes a first screw member fixed at the top of the sleeve member, the lower end of the first screw member is screwed into the threaded pipe member, the lower end of the first screw member and the upper end of the second screw member are in conflict with each other, a first circular ring member is slidably installed in the sleeve member, a spring member is commonly fixed at the upper end of the first circular ring member and the top of the sleeve member, the lower end of the first circular ring member is rotatably connected to the second circular ring member, and the lower end of the second circular ring member is in conflict with the conflict mechanism.

[0023] Furthermore, the staff rotates the first hexagonal nut member to make the first screw member screw into the threaded pipe fitting, so that the first screw member can contact the upper end of the second screw member. At this time, the sleeve member can cover the second hexagonal nut member, which helps to protect the threaded pipe fitting and the second hexagonal nut member, and helps to ensure the stability of the connection between the fixed frame and the U-shaped frame assembly. During disassembly, the first screw member and the second screw member are separated when the first hexagonal nut member is rotated, and then the second screw member and the threaded pipe fitting are separated, so that the threaded pipe fitting can be quickly pulled out, and the separation of the fixed frame and the U-shaped frame assembly is completed, so as to replace the corresponding parts.

[0024] Preferably, a circular groove is provided around the lower end of the first circular ring, a plurality of T-shaped wheel members are installed in the circular groove at equal intervals, and the lower ends of the plurality of T-shaped wheel members are fixed to the upper end of the second circular ring.

[0025] Furthermore, the relative stability of the second circular ring member and the first circular ring member can be ensured, and the relative rotation of the second circular ring member and the first circular ring member is facilitated.

[0026] The present invention also proposes a method for installing and disassembling a connection device between a rail vehicle and a roof device, comprising the following steps:

[0027] S1. During installation, the staff will respectively contact the four fixing frames with the upper ends of the four U-shaped frame assemblies, and the staff will use four threaded pipe fittings to penetrate one end of the installation fixing plate and extend it into the U-shaped frame assembly;

[0028] S2. The staff inserts a hexagonal wrench into the corresponding hexagonal hole member, so that the second screw member can be screwed into the threaded pipe member. The lower end of the second screw member abuts against the abutment plate to lower the insertion rod member. The stability of the lowering of the insertion rod member is ensured by two sliding rod members. The insertion rod member pushes the triangular plate member to lower so that the triangular plate member abuts against the horizontal axis member and the vertical rod member pushes the push rod member so that the pull rod member drives the rotating shaft member to rotate, so that the square frame member can rotate, so that the two second straight tooth conditions correspond to the two first straight tooth conditions respectively.

[0029] S3. When the insert rod is lowered, the two second straight tooth conditions can be separated, and the two second straight tooth conditions can be meshed with the two first straight tooth conditions respectively, so as to ensure that the threaded pipe fitting will not shake along the U-shaped frame assembly. The staff will pass the gasket through the upper end of the threaded pipe fitting, and screw the two second hexagonal nuts together to effectively limit the relative position of the fixing frame and the U-shaped frame assembly.

[0030] S4. The staff drives the sleeve member through the first hexagonal nut member to screw the first screw member into the second screw member, and can effectively push the first circular ring member and the second circular ring member to contact the upper end of the second hexagonal nut member located at the upper end through the spring member, thereby limiting the second hexagonal nut member and preventing it from loosening;

[0031] S5. Place the roof equipment assembly on four L-shaped connecting plates and screw them together with bolts;

[0032] S6. When it is necessary to replace parts, the first screw member and the threaded pipe fitting are separated by rotating the first hexagonal nut member, and the second screw member and the threaded pipe fitting are separated by a hexagonal wrench. At this time, the reset spring member can drive the horizontal axis member to reset, and the square frame member can be reset, so that the threaded pipe fitting can be quickly taken out and replaced.

[0033] The beneficial effects of the present invention are:

[0034] 1. The components in this application are all improved from existing components, which are convenient for production and preparation, and convenient for staff to use, which improves the efficiency of installation and disassembly, and can effectively ensure the structural strength of the components and improve the firmness of the installation of the roof equipment components;

[0035] 2. The staff will match the fixed frame and the U-shaped frame assembly, and pass one end of the threaded pipe fitting to the fixed plate through the fixed frame and extend it into the U-shaped frame assembly. At this time, insert the hexagonal wrench into the hexagonal hole to screw the second screw into the threaded pipe fitting. The lower end of the second screw member presses down the contact plate to make the plug member drive the triangular plate member to descend, providing power for the separation of the two second straight tooth conditions;

[0036] 3. The plug-in rod contacts the horizontal axis so that the fixed rod drives the vertical rod to push the pull rod through the push rod so that the rotating shaft rotates, and the square frame rotates to the vertical state of the threaded pipe. At the same time, the triangular plate and the plug-in rod penetrate the opening, and the two sides of the plug-in rod contact the opposite sides of the two second straight teeth, so that the second straight teeth move out and mesh with the first straight teeth, fixing the position of the threaded pipe, so that the threaded pipe and the fixing frame cannot move along the U-shaped frame assembly, and the four corners of the roof equipment assembly can be accurately clamped;

[0037] 4. The staff can effectively lift the fixing frame and the U-frame assembly to firmly contact each other through the gasket and the two second hexagonal nuts, so that the positional relationship between the fixing frame and the U-frame assembly is fixed. At the same time, when in use, the height of the first straight tooth condition is set according to the actual situation. If necessary, it can be the same as the height in the U-frame assembly, so that the square frame can rise. The square frame will contact the top two sides of the U-frame assembly and cooperate with the gasket and the two second hexagonal nuts to complete the clamping of the fixing frame and the U-frame assembly;

[0038] 5. The staff rotates the first hexagonal nut to screw the first screw into the threaded pipe. The first screw and the second screw collide with each other. At the same time, the second circular ring and the upper end of the second hexagonal nut collide with each other, which helps to limit the position of the components and avoid looseness.

[0039] 6. When disassembly is required, the staff only needs to reversely rotate the first hexagonal nut to separate the first screw member and the second screw member, and then use the hexagonal wrench and the hexagonal hole member to move the second screw member out of the threaded pipe fitting. At this time, the reset spring member can quickly drive the frame member to reset, making it easy to take out and replace the threaded pipe fitting. BRIEF DESCRIPTION OF THE DRAWINGS
