Description

Technical Field

[0001] This utility model belongs to the technical field of 120 valve modules for railway vehicles, specifically relating to a 120 valve module positioning assembly adjustment tooling table. Background Technology

[0002] Currently, the first installation method for assembling the 120 valve module involves transporting it to the bottom of the vehicle and then manually lifting and installing individual components such as the adjusting valve, intermediate body, dual-chamber air cylinder, and auxiliary air cylinder. Finally, the brake piping system between the components is installed. This process is time-consuming and labor-intensive, with a long installation period. Moreover, due to accumulated errors between parts, it is easy to force the assembly of components, resulting in high labor intensity and low production efficiency. The second installation method involves assembling the module on the ground and then manually transporting and lifting it as a whole for installation. Since the valves and air cylinders are not positioned during assembly and are in a free state, the relative position of the mounting surface is inconsistent with the positioning surface of the moving platform, and even the mounting holes are misaligned, resulting in forceful assembly and affecting the assembly quality of the braking system. Utility Model Content

[0003] This utility model aims to provide a 120 valve module positioning assembly adjustment tooling table, which is convenient to install, saves time and effort, and solves the problems of the current assembly of 120 valve modules, which involves transporting them to the bottom of a vehicle and then manually lifting each component for installation, resulting in a time-consuming and labor-intensive process, a long installation period, and inconsistencies between the relative position of the installation surface and the positioning surface of the mobile platform due to the assembly on the ground and then lifting the whole assembly for installation.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a 120 valve module positioning assembly and adjustment fixture, including a horizontal and vertical movable base and a 120 valve module mounting main frame installed on the horizontal and vertical movable base. The 120 valve module mounting main frame is provided with an adjusting valve lifting seat for installing the adjusting valve, a double-chamber air cylinder mounting seat for installing the double-chamber air cylinder, an auxiliary air cylinder mounting seat for installing the auxiliary air cylinder, and an intermediate body lifting seat for installing the 120 valve intermediate body at the designed position. The horizontal and vertical movable base includes a rotating base plate rotatably installed on the 120 valve module assembly and transport trolley and a horizontal movable top plate installed at the bottom of the 120 valve module mounting main frame. A slider mounting plate is provided between the rotating base plate and the horizontal movable top plate. A longitudinal guide rail is provided at the top of the rotating base plate. A longitudinal sliding block that can move along the longitudinal guide rail is provided at the bottom of the slider mounting plate. A transverse guide rail is symmetrically provided on the left and right sides at the bottom of the horizontal movable top plate. A transverse sliding block that can move along the transverse guide rail is provided at the top of the slider mounting plate, thereby driving the 120 valve module mounting main frame to achieve horizontal and vertical adjustment.

[0005] As a preferred embodiment of the above solution, a rotating shaft mounting seat is provided at the center of the rotating base plate, which has a reasonable structure.

[0006] A further preferred embodiment is that the top of the 120 valve module mounting frame is provided with a pipe support column for supporting the braking pipe system between the cylinder and valve, which effectively prevents the pipe system from loosening due to its own weight.

[0007] Further preferably, four slider mounting plates are used, and the bottom of the left and right ends of the 120 valve module mounting frame are equipped with portal-shaped support legs, which are reasonably equipped and make it convenient for workers to stand and work during the initial assembly work.

[0008] Further preferably, the adjusting valve lifting seat and the intermediate body lifting seat both adopt a hand-cranked scissor lift platform, which has a reasonable structure. The top of the double-chamber air cylinder mounting seat and the auxiliary air cylinder mounting seat are provided with an arc surface structure that fits into the corresponding cylinder body, so that the installation is stable.

[0009] The beneficial effects of this utility model are:

[0010] (1) Compared with the current assembly of 120 valve modules, which involves transporting the modules to the bottom of the vehicle and then manually lifting each component for installation, or assembling them on the ground and then lifting them as a whole for installation, this solution uses a 120 valve module positioning group to install the adjustment tooling table. The rotating base plate can be rotatably installed on the 120 valve module assembly and transport trolley via a rotating shaft installed on the rotating shaft mounting seat. The horizontal and vertical movable base ensures that the 120 valve module positioning group can adjust the adjustment tooling table horizontally and vertically. In this way, after the 120 valve module assembly and transport trolley is transported to the bottom of the vehicle, it can complete the rotation and horizontal and vertical movement for precise positioning and assembly, saving time and effort, making installation and transportation convenient and quick, and simple to operate. It effectively reduces the workload of the staff and shortens the installation period of the 120 valve module.

[0011] (2) The main frame for installing the 120 valve module is equipped with a regulating valve lifting seat for installing the regulating valve, a double-chamber air cylinder mounting seat for installing the double-chamber air cylinder, an auxiliary air cylinder mounting seat for installing the auxiliary air cylinder, and an intermediate body lifting seat for installing the intermediate body of the 120 valve. The design structure is reasonable and convenient for workers to install accurately. It can be accurately positioned during component assembly. When it is lifted to the bottom of the vehicle, the relative position of the mounting surface can be made consistent with the positioning surface of the positioning assembly adjustment tooling table after adjusting the horizontal and vertical rotation angles. This effectively avoids the situation of misalignment of mounting holes and forced assembly.

[0012] In summary, it has advantages such as precise positioning and assembly, saving time and effort, convenient and quick installation and transportation, simple operation, and effectively reducing the workload of staff. Attached Figure Description
