Description

Technical Field

[0001] The utility model relates to the technical field of underground hydraulic support assembly tooling, in particular to a multifunctional adjustable assembly device for an ear - shaft type cylinder barrel. Background Technique

[0002] During the roof support process in underground coal mines, due to the limitation of the working space and the different structural positions, the structural forms of hydraulic cylinder barrels are also different. For some special support structures, ear - shaft type cylinder barrels are derived to meet the use requirements. The ear - shaft type cylinder barrels include opposed - ear - shaft type cylinder barrels and single - shaft type cylinder barrels. Currently, most of the common ones are opposed - ear - shaft type cylinder barrels.

[0003] Since the ear - shaft heights of the opposed - ear - shaft type cylinder barrels are not the same, the current assembly method for the opposed - ear - shaft type cylinder barrels is to make a tooling jig for each set of supports for assembly. Although the existing tooling jigs can complete simple assembly tasks, during the installation process, the cylinder barrel is prone to tilt and scratch the outer wall of the cylinder barrel, and the ear - shaft installation height is prone to error. If a separately - matched assembly tooling is used to reduce the installation error, an independent tooling needs to be made for each set of supports. However, this solution will result in too single use. After this use, it cannot be used for the assembly of opposed - ear - shaft type cylinder barrels with different heights next time, resulting in a large number of toolings being idle and wasted, and increasing the production cost of the enterprise.

[0004] How to design a multifunctional adjustable assembly device for an ear - shaft type cylinder barrel that is ingeniously designed, simple in structure, can assemble various ear - shaft type cylinder barrels, ensure the installation stability and the accuracy of ear - shaft installation, is convenient for observation, greatly reduces the assembly difficulty, reduces the labor intensity of workers, greatly reduces the operation difficulty, and improves the production efficiency is the problem that needs to be solved currently. Content of the Utility Model

[0005] In order to solve the technical problems existing in the assembly of the ear - shafts of the existing ear - shaft type cylinder barrels, such as single assembly tooling, poor installation stability and ear - shaft installation accuracy, inability to observe at any time, low assembly efficiency, high labor intensity of workers, and seriously affecting the production efficiency, the utility model provides a multifunctional adjustable assembly device for an ear - shaft type cylinder barrel to achieve the purposes of ingenious design, simple structure, being able to assemble various ear - shaft type cylinder barrels, ensuring the installation stability and the accuracy of ear - shaft installation, being convenient for observation, greatly reducing the assembly difficulty, reducing the labor intensity of workers, greatly reducing the operation difficulty, and improving the production efficiency.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is: a multifunctional adjustable assembly device for a trunnion-type cylinder barrel, including a guiding cylinder, a fixed bottom plate, a height adjustment mechanism and an observation mechanism. The guiding cylinder is a hollow cylindrical structure. The left and right sides of the top of the guiding cylinder bulge upward to form two equal-height wing plates. Positioning grooves for placing the cylinder barrel trunnions are provided on the wing plates. The inner wall of the wing plate is recessed, and together with the inner wall of the guiding cylinder, it forms an inverted boss structure for clamping the trunnion seat of the cylinder barrel. The fixed bottom plate is horizontally fixed at the lower part inside the guiding cylinder. An internal threaded hole for installing the height adjustment mechanism is provided at the center of the fixed bottom plate. The height adjustment mechanism includes a movable support plate for placing the cylinder barrel body, a height adjustment threaded shaft and a rotating handle. The height adjustment threaded shaft is fixedly connected by threads in the internal threaded hole of the fixed bottom plate. The movable support plate is fixed at the upper end of the height adjustment threaded shaft, and the rotating handle is located at the lower end of the height adjustment threaded shaft. By screwing the rotating handle, the movable support plate is driven to move up and down to adjust the assembly height of the cylinder barrel body.

[0007] As a further optimized solution of the above multifunctional adjustable assembly device for a trunnion-type cylinder barrel, the observation mechanism includes a transparent plate and a scale. The transparent plate is embedded on the wall of the guiding cylinder, and the scale is arranged on the transparent plate. By observing the scale position on the scale where the upper edge of the movable support plate stops, the rising height of the cylinder barrel body is adjusted.

[0008] As a further optimized solution of the above multifunctional adjustable assembly device for a trunnion-type cylinder barrel, the scale is arranged with the scale direction from bottom to top, and the reset position of the movable support plate is at the zero scale.

[0009] As a further optimized solution of the above multifunctional adjustable assembly device for a trunnion-type cylinder barrel, the adjustable dimension range of the scale is 0 - 100 mm.

[0010] Compared with the prior art, the beneficial effects of the present utility model are:

[0011] First, the present utility model includes a guiding cylinder, a fixed bottom plate, a height adjustment mechanism and an observation mechanism. By controlling the assembly height of the cylinder barrel body and the installation position of the trunnion through the height adjustment mechanism, the assembly jig for the trunnion-type cylinder barrel is optimized, enabling multiple trunnion-type cylinder barrels to be assembled using the same adjustable tooling jig, thus achieving the purpose of improving production efficiency and saving processing costs.

[0012] Second, the observation mechanism includes a transparent plate and a scale. The transparent plate is embedded on the wall of the guiding cylinder, and the scale is arranged on the transparent plate. By observing the scale position on the scale where the upper edge of the movable support plate stops, the rising height of the cylinder barrel body is adjusted. During use, the rising height can be observed at any time through the transparent plate, which is convenient for reducing installation errors and ensuring installation accuracy.
