Description

Technical Field

[0001] The utility model belongs to the field of machine tools, in particular to a cooling pool for a drilling machine. Background Art

[0002] The Z33100 drilling machine is a large drilling machine equipped with a cooling pool on the bed. The coolant in the pool is delivered to the parts requiring cooling via a cooling pump. The cooling pump requires a pump motor as power when in operation. Because the coolant level in the cooling pool is constantly changing, the cooling pump and its motor are mounted on a floating seat. The seat floats on the coolant surface and automatically adjusts its height as the level changes. With this installation method, the coolant in the pool can easily splash onto the pump motor, causing it to burn out. Furthermore, the cooling pool cannot be covered, allowing dust, chips, and other debris to fall into the coolant, causing pipe blockage and affecting the cooling effect. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] The drilling machine cooling pool of the utility model is as follows: Figure 1 As shown, it includes a pool body 1 and a cooling pump 2. The pool body 1 is the original cooling pool body of the Z33100 drilling machine, and the cooling pump 2 adopts an existing liquid delivery pump and uses a pump motor as power.

[0022] A certain amount of coolant is stored in the tank body 1. A cover plate 3 is provided on the top of the tank body 1. The cover plate 3 is a metal plate that can cover the upper port of the tank body 1 and seal the upper port of the tank body 1 to prevent dust, chips and other debris from outside from falling into the coolant in the tank body 1. In order to facilitate the addition of coolant to the tank body 1, an addition port can be opened on the cover plate 3, and a sealing plate that can be opened and closed is provided inside the addition port.

[0023] The cooling pump 2 is installed on the upper surface of the cover plate 3, and the pump motor of the cooling pump 2 is also installed on the upper surface of the cover plate 3. The cover plate 3 isolates the coolant inside the pool body 1 from the pump motor, which can effectively prevent the coolant from splashing onto the pump motor and causing the pump motor to burn, thereby improving the safety and service life of the pump motor.

[0024] The inlet of the cooling pump 2 is connected to a liquid inlet pipe 4, which passes through the cover plate 3 and extends into the bottom of the tank body 1. The liquid inlet pipe 4 can specifically be an inverted L-shaped metal pipe. When the cooling pump 2 is in operation, the coolant inside the tank body 1 enters the cooling pump 2 along the liquid inlet pipe 4. The outlet of the cooling pump 2 is connected to a cooling pipe 5, which is connected to the parts of the drilling machine that need to be cooled. The cooling pipe 5 is connected to an overflow pipe 6, which is in communication with the liquid inlet pipe 4 and is provided with a regulating valve 7. The cooling pipe 5 includes a metal joint and a delivery hose. The metal joint can be a tee joint, which has an inlet and two outlets. The inlet of the tee joint is connected to the outlet of the cooling pump 2, and the delivery hose and the overflow pipe 6 are respectively connected to an outlet of the tee joint. Since the parts of the drilling machine that need to be cooled usually need to be moved, the main body of the cooling pipe 5 is a delivery hose that can be bent, and the outlet of the cooling pipe 5 can move synchronously with the moving parts. The overflow pipe 6 can be a metal pipe or a hose. Under different working conditions, the coolant flow rate required by the drilling machine is different. In the present invention, an overflow pipe 6 is added, and a regulating valve 7 is provided on the overflow pipe 6. Part of the coolant output by the cooling pump 2 enters the cooling pipe 5 to cool the drilling machine components, and part of it flows back to the liquid inlet pipe 4 through the overflow pipe 6. The coolant flow rate returning to the liquid inlet pipe 4 can be adjusted by the regulating valve 7, thereby adjusting the coolant flow rate entering the cooling pipe 5. By adjusting the coolant supply through the regulating valve 7, there is no need to adjust the coolant flow rate through the cooling pump 2. The flow rate adjustment is convenient, and the cooling pump 2 can operate under stable power. The regulating valve 7 can specifically adopt a conventional valve such as a ball valve.

[0025] In order to prevent solid impurities in the coolant from entering the liquid inlet pipe 4 and other pipelines, a filtering mechanism is provided at the inlet end of the liquid inlet pipe 4. The filtering mechanism can adopt various existing filtering equipment. Preferably, the filtering mechanism includes a filter cartridge 8. The filter cartridge 8 can adopt a cylindrical stainless steel cylinder. The side walls and bottom walls of the cylinder are provided with fine filter holes, which can filter out solid particles with larger particle sizes. A detachable top plate 10 is provided on the top of the filter cartridge 8, and the inlet end of the liquid inlet pipe 4 is connected to the top plate 10. Specifically, the top plate 10 adopts a metal plate, and a through hole is provided on the top plate 10. The inlet end of the liquid inlet pipe 4 is located in the through hole, and the liquid inlet pipe 4 can be welded to the top plate 10. The top plate 10 can be connected to the filter cartridge 8 by screws. When replacing the filter cartridge 8, the top plate 100 can be removed from the filter cartridge 8.

[0026] To facilitate the collection of filtered solid impurities, a collection cylinder 18 is provided within the tank body 1. This cylinder can be a wire mesh cylinder with an open top and a sealed bottom with a mesh plate or end plate. A removable, water-permeable collection bag 9 is located within the collection cylinder 18. A filter cylinder 8 is positioned within the collection cylinder 18 and also within the collection bag 9, allowing the filter cylinder 8 to naturally rest within the collection cylinder 18. After being filtered by the filter cylinder 8, the solid impurities in the coolant remain within the collection bag 9. After a period of use, the collection bag 9 can be removed to retrieve the filtered solid impurities.

[0027] When the coolant is used to cool the drilling machine parts, solid impurities inevitably mix into the coolant. In order to separate the solid impurities, the inner cavity of the tank body 1 is divided into a sedimentation chamber 14 and a collection chamber 15 by a vertical partition 13. The upper part of the partition 13 is provided with a plurality of water holes 16 evenly distributed in the vertical direction. The lower end of the partition 13 is sealed with the bottom of the tank body 1, and the upper end of the partition 13 is lower than the highest liquid level of the coolant. The inlet end of the liquid inlet pipe 4 is located at the bottom of the collection chamber 15, and the sedimentation chamber 14 is connected to the return pipe 17. The return pipe 17 is used to transport the coolant into the tank body 1. After the coolant enters the sedimentation chamber 14, the solid impurities settle to the bottom of the sedimentation chamber 14, and the supernatant flows into the collection chamber 15 through the water holes 16 or above the partition 13. Since the liquid level of the coolant fluctuates, a plurality of water holes 16 of different heights are provided. When the liquid levels of the sedimentation chamber 14 and the collection chamber 15 are higher, the coolant in the sedimentation chamber 14 can flow into the collection chamber 15 through the water holes 16 and above the partition 13; when the liquid levels of the sedimentation chamber 14 and the collection chamber 15 are lower, the coolant in the sedimentation chamber 14 can flow into the collection chamber 15 through the water holes 16 corresponding to the liquid level height.

[0028] The sedimentation chamber 14 and the filtering mechanism respectively precipitate and filter the coolant, which can effectively reduce the solid impurity content in the coolant and prevent pipeline blockage.

[0029] In order to facilitate monitoring of the coolant level in the pool body 1, a liquid level gauge 11 is provided in the pool body 1. The liquid level gauge 11 can be made using existing technology. When the coolant level in the pool body 1 is low, coolant can be added to the pool body 1.

[0030] In order to facilitate installation and removal of the cover plate 3, a positioning groove is provided on the upper surface of the pool body 1, and the cover plate 3 is naturally placed in the positioning groove.

[0031] The top surface of the cover plate 3 is provided with a mounting base 12, to which the cooling pump 2 is mounted. Mounting base 12 specifically comprises four side panels and a top panel. The edges of the top panel are welded to the upper ends of the side panels, and the lower ends of the side panels are bolted to the cover plate 3. Mounting base 12 supports the cooling pump 2 at a suitable height.

[0032] This new system can be directly modified based on the existing cooling pool of the Z33100 drilling machine. Specifically, a partition 13, a collection tube 18, and a collection bag 9 are added to the interior of the pool body 1. A cover plate 3 is added to the top of the pool body 1, eliminating the buoyancy seat. The cooling pump 2 is installed on the upper surface of the cover plate 3, and the piping can be adaptively adjusted. This low-cost modification reduces the maintenance frequency of the cooling pump 2's pump motor, reduces the frequency of pipeline blockage, and makes it easier to control the coolant supply.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
