Description

Technical Field

[0001] The utility model relates to the technical field of liquid level meter installation, in particular to a portable liquid level meter connecting flange assembly tool. Background Art

[0002] Liquid level gauges are widely used in chemical equipment. Liquid level gauges are used to observe the liquid level in the equipment. The installation of the liquid level gauge flange is relatively strict, with the following requirements: (1) The screw holes of the liquid level gauge flange must be arranged symmetrically in the middle of the span; (2) The distance between the vertical lines of the center of the liquid level gauge flange should not exceed 1.5 mm. (3) The sealing surfaces of the two pipe flanges should be in the same vertical plane, and the allowable deviation of the verticality should not exceed 1 mm.

[0003] The traditional level gauge connection flange assembly tooling uses angle steel, round plates and other materials to make the level gauge auxiliary device. However, this type of assembly tooling needs to replace different round plates when assembling level gauge connection flanges of different specifications. The installation cost is high and the labor intensity of workers is high, and the precision tolerance is difficult to control.

[0004] There are also assembly tools suitable for different types of liquid level gauge flanges in the prior art, such as patent number 201820509182.9, and the patent name is adjustable assembly tool suitable for different types of liquid level gauge flanges. This tool effectively improves the assembly efficiency of the liquid level gauge connecting flange, but the length of the steel pipe in the assembly tool is fixed. If you want to adapt to liquid level gauges with different spacings, the length of the steel pipe is also relatively long, which is very inconvenient to carry out; at the same time, the accuracy of the position of the sleeve fixed by the top screw is not easy to control, which affects the assembly accuracy of the liquid level gauge connecting flange. Summary of the invention

[0005] In order to solve the problems in the prior art that the level gauge flange assembly tool is inconvenient to carry and the assembly precision is difficult to control, the utility model provides a new portable level gauge connection flange assembly tool.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A portable level gauge connecting flange assembly tool, comprising a gear box, a gear rack component, and two connecting components;

[0008] The gear box includes a rectangular box body surrounded by a front baffle, a rear baffle, a left baffle, a right baffle, an upper cover plate, and a lower cover plate. The upper cover plate and the lower cover plate are respectively provided with an upper sliding hole and a lower sliding hole. The center of the left baffle plate and the right baffle plate are respectively provided with a left center hole and a right center hole. An internal thread and a top screw matched with the internal thread are coaxially fixed in the left center hole. A fixed bearing is coaxially fixed in the right center hole.

[0009] The gear rack component includes a rotating shaft, a gear whose axial direction is arranged along the left-right direction, and two racks whose one ends are symmetrically adapted to the front and rear sides of the gear respectively, the rotating shaft is coaxially fixed in a fixed bearing, one end of the rotating shaft is located in the gear box and is coaxially fixedly connected to the gear, the other end of the rotating shaft extends outside the gear box and is fixed with a rotating handle, the width of one end of the two racks is greater than the width of the other end, and the other ends of the two racks are respectively slidably connected to the upper sliding hole and the lower sliding hole of the gear box, the vertical center lines of the other ends of the two racks in the front-to-back direction coincide, and the front and rear side surfaces of the two racks that are not adapted to the gears are both slidably connected to the inner walls of the front and rear baffles (in specific implementation, the aforementioned sliding connection can be achieved by the structure of a track and a slider, and can also be achieved by the clamping assembly described below);

[0010] The two connecting components each include a cylindrical block, which is respectively fixed to the left side or right side of the other end of the two racks. The two cylindrical blocks are symmetrically arranged about the gears. Four connecting plates are evenly distributed circumferentially on the circular axis wall of one end of the cylindrical block. Bolt holes matching the connecting flange of the liquid level meter are opened on the four connecting plates, and matching bolts and nuts are arranged in the threaded holes.

[0011] When in use, adjust the rotating handle according to the center distance of the liquid level gauge, and use a box ruler to measure the center distance between the two cylindrical blocks. Tighten the top screw until the center distance between the two cylindrical blocks reaches the required size of the center distance of the liquid level gauge, so that the top screw is pressed against the rotating shaft, and then the liquid level gauge connecting flange is fastened to the connecting plate by bolts and nuts. Finally, the tool is manually lifted to assemble and weld the liquid level gauge connecting flange with the chemical equipment, and then the tool is separated from the liquid level gauge connecting flange, so as to complete the assembly of the liquid level gauge connecting flange; at the same time, after the use of the assembly tool, the rotating handle can be appropriately adjusted so that the two ends of the assembly tool (i.e., the two racks) are retracted toward the gear box, thereby effectively shortening the length of the assembly tool after collection and improving the portability of the assembly tool; in addition, the assembly tool realizes the adjustment of the center distance of the liquid level gauge through the gear rack mechanism, which is simple to operate, has low labor intensity for workers, high assembly efficiency and high assembly accuracy.

[0012] Furthermore, the four connecting plates are all strip-shaped connecting plates, and the shape of the bolt holes is oblong, which is convenient for adapting to different types of liquid level gauge flange connecting plates.

[0013] Furthermore, two locking assemblies are fixed on the inner walls of the front and rear baffles, and each locking assembly includes two bearing seats arranged on the left and right sides of the inner wall of the corresponding baffle, and the axial directions of the two bearing seats are arranged in the left and right directions. Locking bearings are fixed in the two bearing seats, and a rolling shaft is fixed between the two locking bearings. The side surface of one end of the corresponding rack that is not adapted to the gear abuts against the rolling shaft and is clamped between the two bearing seats, so that one end of the two racks can be slidably connected to the inner walls of the front and rear baffles up and down respectively. The structure is simple and easy to implement.

[0014] Furthermore, a round protrusion with external threads is protruded outwardly on the end surface of the other end of the cylindrical block, and internal threaded holes matching the external threads on the cylindrical protrusion are provided on the other ends of the two racks, so as to facilitate the installation and disassembly of the cylindrical block and the racks.

[0015] Furthermore, a portable handle is fixed on the left baffle for easy carrying.

[0016] The beneficial effects of the utility model are as follows: 1) the assembly efficiency of the liquid level gauge connecting flange is improved, and the labor intensity of workers is reduced; 2) the length of the assembly tool is retractable, which is convenient to carry outside, and the center distance of the liquid level gauge is adjusted by the gear rack structure, which effectively improves the assembly accuracy of the liquid level gauge flange.
