[0001] The utility model relates to the technical field of control devices, in particular to a hydraulic control device for a vehicle-mounted drill rig. Background Art

[0002] During the operation of a vehicle-mounted drill rig, a hydraulic control device is required to precisely control the hydraulic system to ensure that the drill rig can complete the operation tasks efficiently and stably. As an important part of the hydraulic system, the hydraulic control device plays a crucial role in the performance and operation efficiency of the vehicle-mounted drill rig.

[0003] In the prior art, during the working process of a vehicle-mounted drill rig, it is necessary to precisely control the hydraulic system of the drill rig through a hydraulic control device, so as to make the working efficiency of the drill rig higher. Since a large amount of dust or impurities will appear during the use of the drill rig, and there are many precision detection devices or modules inside the hydraulic control device, when cooling the inside of the hydraulic control device, external dust and impurities will also enter it, which will damage the electronic components inside the control device, shorten its service life, and thus cannot precisely control the hydraulic system and affect the working efficiency of the vehicle-mounted drill rig. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the inability to prevent dust and impurities from entering the inside of the control device, electronic component damage and inaccurate control of the hydraulic system will occur during the use process, and thus a hydraulic control device for a vehicle-mounted drill rig is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A hydraulic control device for a vehicle-mounted drill rig includes a housing. One side of the outer wall of the housing is fixedly installed with a filter box. One side of the outer wall of the filter box is fixedly communicated with a delivery pipe, and the outer surface of the delivery pipe is fixedly inserted into the inside of the housing. A blower is arranged inside the delivery pipe. A filtering device is arranged inside the filter box. Two fixing grooves are opened at the top of the filtering device. Limiting springs are arranged on the inner surfaces of the two fixing grooves. Limiting rods are fixedly installed on one sides of the outer walls of the two limiting springs. Three baffle plates are arranged on the inner surface of the filter box. A water delivery pipe is fixedly installed between the outer surfaces of the three baffle plates.

[0006] Preferably, a top cover is arranged on the top of the filter box.

[0007] Preferably, a cooling device is fixedly installed on the top of the top cover, and the outer surface of the cooling device is fixedly communicated with the outer surface of the water delivery pipe.

[0008] Preferably, a control device main body is fixedly installed at the bottom of the inner wall of the housing, and two side covers are fixedly installed on the outer surface of the housing.

[0009] Preferably, an installation groove is formed on one side of the outer wall of the housing.

[0010] Preferably, a dust-proof net is provided on the inner surface of the installation groove, and two square grooves are formed on one side of the outer wall of the housing.

[0011] Preferably, compression springs are arranged inside the two square grooves, limit blocks are arranged on one side of the outer walls of the two compression springs, and the outer surface of the limit block is movably embedded inside the square groove.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] During the use of the present utility model, through the interaction of a series of components, when heat dissipation treatment is required for the hydraulic control device, firstly, under the action of the fan and the conveying pipe, external air can be inhaled into the filter box, and under the action of the filtering device, dust and impurities in the air are filtered to prevent dust and impurities from entering the interior of the housing, thereby protecting the electronic components in the hydraulic control device from being damaged. Then, under the action of the cooling device and the water conveying pipe, the filtered air can be cooled, and under the action of the baffle, the air can be cooled more sufficiently, thereby improving the heat dissipation effect on the hydraulic control device, and further completing the precise control of the hydraulic system and improving the working efficiency of the drilling rig.

[0014] During the use of the present utility model, through the interaction of a series of components, after the device has been used for a long time, a large amount of dust and impurities will adhere to the outer surfaces of the filtering device and the dust-proof net. Through the interaction of the limiting spring, the limiting rod, the compression spring and the limit block, the filtering device and the dust-proof net can be quickly disassembled, replaced or cleaned, thereby improving the replacement and cleaning efficiency, and also improving the heat dissipation efficiency of the hydraulic control device.

[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1 - 4 shown, the present utility model provides a vehicle-mounted drill hydraulic control device, including an outer shell 1. One side of the outer wall of the outer shell 1 is fixedly installed with a filter box 9. One side of the outer wall of the filter box 9 is fixedly communicated with a delivery pipe 10, and the outer surface of the delivery pipe 10 is fixedly inserted into the interior of the outer shell 1. A fan 11 is arranged inside the delivery pipe 10. A filter device 12 is arranged inside the filter box 9. Two fixed grooves 13 are opened at the top of the filter device 12. Limit springs 14 are arranged on the inner surfaces of the two fixed grooves 13. Limit rods 15 are fixedly installed on one sides of the outer walls of the two limit springs 14. Three baffles 16 are arranged on the inner surface of the filter box 9. A water delivery pipe 17 is fixedly installed between the outer surfaces of the three baffles 16. A top cover 19 is arranged on the top of the filter box 9. A cooling device 18 is fixedly installed on the top of the top cover 19, and the outer surface of the cooling device 18 is fixedly communicated with the outer surface of the water delivery pipe 17.

[0024] The effect achieved by the entire Embodiment 1 is that when heat dissipation is required for the hydraulic control device, first, under the action of the fan 11, air is inhaled from the notch opened on the outer wall of the filter box 9 into the interior of the filter box 9 and reaches the interior of the filtering device 12. The primary filter screen and the precision filter screen arranged inside the filtering device 12 can adsorb impurities and dust in the air. At the same time, under the action of the activated carbon filter screen, dust and moisture in the air can be removed, playing a protective role for the hydraulic control device. Then, under the action of the water pump arranged inside the cooling device 18, the cooling water in the water delivery pipe 17 can circulate, and the heat in the air can be absorbed. At the same time, under the action of the fan arranged inside the cooling device 18, the cooling water circulated to the cooling device 18 can be cooled, so that the cooling water can continuously absorb heat and cool the air for a long time. And under the action of the baffle 16, the air can move slower, improving the cooling effect of the air. Subsequently, it reaches the interior of the housing 1 through the delivery pipe 10, thereby dissipating heat and cooling the hydraulic control device and prolonging its service life.

[0025] Embodiment 2, as Figures 2 - 4 shown, a control device main body 2 is fixedly installed at the bottom of the inner wall of the housing 1. Two side covers 3 are fixedly installed on the outer surface wall of the housing 1. An installation groove 4 is opened on one side of the outer wall of the housing 1. A dust-proof net 5 is arranged on the inner surface wall of the installation groove 4. Two square grooves 6 are opened on one side of the outer wall of the housing 1. Compression springs 7 are arranged inside both of the two square grooves 6. Limiting blocks 8 are arranged on one side of the outer walls of both of the two compression springs 7, and the outer surface wall of the limiting block 8 is movably embedded inside the square groove 6.

[0026] The effect achieved by the entire Embodiment 2 is that during use, the dust-proof net 5 can convey the air inside the housing 1 to the outside, making the air inside the housing 1 circulate and improving the heat dissipation efficiency. And it can prevent dust and impurities outside the housing 1 from entering the interior of the housing 1, thereby playing a further protective role for the hydraulic control device. After long-term use, a large amount of dust and impurities will adhere to the outer surface wall of the dust-proof net 5. At this time, under the action of the staff, the limiting block 8 can be pressed to move it to both sides inside the square groove 6, and then the dust-proof net 5 can be quickly disassembled and cleaned, which can increase the air circulation speed and thus improve the heat dissipation efficiency of the hydraulic control device.

[0027] Working principle: During the working process of the vehicle-mounted drill rig, the hydraulic control device of the drill rig is controlled for a long time, and a large amount of heat will be generated by the hydraulic control device. At this time, under the action of the fan 11, air is inhaled from the notch opened on the outer wall of the filter box 9 into the interior of the filter box 9 and reaches the interior of the filtering device 12. The primary filter screen and the precision filter screen arranged inside the filtering device 12 can adsorb impurities and dust in the air. At the same time, under the action of the activated carbon filter screen, dust and moisture in the air can be removed, which plays a protective role for the hydraulic control device. Then, under the action of the water pump arranged inside the cooling device 18, the cooling water in the water delivery pipe 17 can circulate, and the heat in the air can be absorbed. At the same time, under the action of the fan arranged inside the cooling device 18, the cooling water circulated to the cooling device 18 can be dissipated, so that the cooling water can continuously absorb heat and cool the air for a long time. And under the action of the baffle 16, the air can move slower, improving the cooling effect of the air. Subsequently, it reaches the interior of the housing 1 through the delivery pipe 10 to dissipate heat from the hydraulic control device. Then, the air that absorbs heat inside the housing 1 will flow outwards from the dust-proof net 5, improving the heat dissipation efficiency of the hydraulic control device. After a long time of use, a large amount of dust and impurities will adhere to the outer walls of the dust-proof net 5 and the filtering device 12. By pressing the limit block 8 and the limit spring 14, the dust-proof net 5 and the filtering device 12 can be quickly disassembled, and after cleaning and replacement, they can be quickly installed, thereby increasing the air flow rate and improving the heat dissipation efficiency of the hydraulic control device.

[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
