Abstract
Description
Technical Field
[0001] This utility model relates to a working frame for cleaning the sand shell inside the impeller of a pump body, and particularly to an auxiliary tool for cleaning the internal flow channels of pump and valve castings, belonging to the field of casting cleaning technology. Background Technology
[0002] During the production of pump and valve castings, sand, impurities, rust, and other substances often remain in the internal flow channels. If these residues are not cleaned in time, they can cause blockages in the flow channels, reduce the performance of pumps and valves, and may even lead to equipment failure and affect normal production. Traditional cleaning methods often involve manually using a water gun to clean the inner cavity of the casting. To ensure thorough cleaning, the casting must be kept upright during the process. However, due to the excessive pressure of the water gun, the casting is prone to tipping over. Therefore, during the cleaning process, workers need to constantly adjust the placement of the casting, which not only increases the complexity and danger of the operation but also seriously affects the cleaning progress and quality. Utility Model Content
[0003] The technical solution adopted by this utility model to solve the technical problem is as follows: An auxiliary tool for cleaning the internal flow channels of pump and valve castings includes a rectangular frame, a load-bearing net at the bottom of the rectangular frame, two limiting crossbars at the top of the rectangular frame, and limiting longitudinal bars at the top of the two limiting crossbars. Support legs are provided at the four corners of the bottom of the rectangular frame.
[0004] The limiting crossbar has slots at both ends, which are fitted onto the rectangular frame and fixed with bolts.
[0005] There are at least two limiting longitudinal bars, and the limiting longitudinal bars are fixedly connected to the limiting transverse bars by bolts.
[0006] The distance between the two limiting crossbars matches the size of the pump body impeller, so that the pump body impeller is locked between the two limiting crossbars; limiting longitudinal bars are respectively provided on the limiting crossbars on both sides of the pump body impeller, thereby limiting the two sides of the pump body impeller.
[0007] The positive and beneficial effects of this utility model are: 1. This utility model sets two limiting crossbars at the top of the rectangular frame and sets limiting longitudinal bars on the limiting crossbars, so that the pump body impeller remains upright during the cleaning process. This avoids the repeated adjustments caused by the shaking of the casting in the traditional cleaning method, makes it easier for workers to clean the inner cavity of the pump body impeller, improves work efficiency, and ensures the cleanliness of the casting.
[0008] 2. By setting slots at both ends of the limiting crossbar, this utility model allows for free adjustment of the distance between the two limiting crossbars according to the size of the pump casting, ensuring that castings of different specifications can be stably locked between the limiting crossbars. This improves the applicability of the tool, making it convenient and easy to use. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the rectangular frame structure of this utility model; Figure 3 This is a schematic diagram of the limiting crossbar of this utility model; Among them: 1-rectangular frame, 2-support leg, 3-load-bearing mesh, 4-limiting crossbar, 5-slot, 6-limiting longitudinal bar, A-pump and valve casting. Detailed Implementation
[0010] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-3 An auxiliary tool for cleaning the internal flow channels of pump and valve castings includes a rectangular frame 1, a load-bearing net 3 at the bottom of the rectangular frame 1, two limiting crossbars 4 at the top of the rectangular frame 1, and limiting longitudinal bars 6 at the top of the two limiting crossbars 4. Support legs 2 are provided at the four corners of the bottom of the rectangular frame 1.
[0011] In the above description, the load-bearing mesh is located at the bottom of the inner wall of the rectangular frame.
[0012] Slots 5 are provided at both ends of the limiting crossbar 4. The slots 5 are fitted onto the rectangular frame 1 and fixed by bolts.
[0013] In the above description, the internal dimensions of the slot match the dimensions of the end support rod of the rectangular frame. When the slot is fitted onto the end support rod of the rectangular frame, the limiting crossbar is fixedly connected to the rectangular frame by bolts on the outer wall of the slot.
[0014] There are at least two limiting longitudinal bars 6, and the limiting longitudinal bars 6 are fixedly connected to the limiting transverse bars 4 by bolts.
[0015] In the above description, the limiting longitudinal bar and the limiting transverse bar are distributed in a cross shape, and the two ends of the limiting longitudinal bar are located at the top of the corresponding limiting transverse bar and are fixed by bolts.
[0016] The distance between the two limiting crossbars 4 is matched with the size of the pump body impeller A, so that the pump body impeller A is stuck between the two limiting crossbars 4; limiting longitudinal bars 6 are respectively set on the limiting crossbars 4 on both sides of the pump body impeller A, so as to limit the two sides of the pump body impeller A.
[0017] The top of the limiting crossbar 4 is provided with at least two mounting holes; in use, a through hole is opened at the end of the limiting longitudinal bar corresponding to the mounting hole for bolt installation.
[0018] In the above description, the distance between the limiting crossbar and the load-bearing mesh satisfies the following condition: the lower part of the casting is placed on the load-bearing mesh, and the casting is fixed by the limiting crossbar and the limiting longitudinal bar.
[0019] When using it, adjust the distance between the two limit crossbars according to the size of the impeller pump body, then place the impeller pump body to be cleaned between the two limit crossbars, and install limit longitudinal bars on both sides of the impeller pump body to fix the impeller pump body; finally, use a water gun to clean the inner cavity of the impeller pump body.
[0020] This utility model sets two limiting crossbars at the top of a rectangular frame, and sets limiting longitudinal bars on the limiting crossbars, so that the pump impeller remains upright during the cleaning process. This avoids the repeated adjustments caused by the shaking of the casting in traditional cleaning methods, making it easier for workers to clean the inner cavity of the pump impeller, improving work efficiency, ensuring the cleanliness of the casting, and being convenient and easy to use.
