[0003] In order to be widely applicable to mobile operations, multiple pump units of a high-pressure pump are usually assembled together with an engine and a base as an integral assembly to form a high-pressure pump that is easy to transport. This type of high-pressure pump that is easy to transport ensures the concentricity of the unit, and the drive connection between the engine and the pump adopts the internationally advanced automatic adjustment high-elastic drive connection, which overcomes the problems of the cancellation-type coupling transmission that often requires maintenance and replacement of pins, replacement of elastic rings, and falling off of pin nuts under long-term vibration, thereby ensuring the long-term good operation of the entire machine under maximum load. During the use of the high-pressure pump that is easy to transport, the high-pressure pump unit is often moved and transported, and the high-pressure pump unit is often large in size and heavy in weight, which is very inconvenient. For this reason, a public technology proposes a high-pressure pump unit that is easy to move, which belongs to the field of high-pressure pump technology. The high-pressure pump group that is easy to move includes a mobile body, a pump body and a support assembly, wherein the pump body is fixedly connected to the upper part of the mobile body, and the support assembly includes a slide rail, a telescopic frame and a first telescopic member, wherein the upper part of the slide rail is fixedly connected to the bottom of the mobile body, one side of the telescopic frame is rotatably connected to one side of the slide rail, the end of the first telescopic member is rotatably connected to the slide rail, the output end of the first telescopic member is rotatably connected to the middle part of the telescopic frame, and the telescopic frame and the first telescopic member are symmetrically arranged. The mobility of the high-pressure pump group is improved;

[0004] Another disclosed technology proposes a mobile fire room high-pressure pump that is easy to disassemble and assemble, which belongs to the field of high-pressure pumps and includes a pump body and a base.

A roller is fixedly installed at the bottom end of the storage mechanism. The mobile fire room high-pressure pump that is easy to disassemble and assemble can be conveniently moved according to the location of the fire by providing the base and the roller, thereby speeding up the fire rescue speed of the high-pressure pump. Moreover, by providing the storage mechanism, the roller can be conveniently stored, thereby avoiding the problem of the roller being damaged due to long-term force, thereby increasing the service life of the roller.

[0005] However, the above-mentioned public technology is only suitable for short-distance transportation and transfer of high-pressure pumps that are easy to transport, and it also needs to be pushed manually, which is quite laborious.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example:

[0035] like Figures 1 to 8 As shown, an embodiment of the present invention provides a high-pressure pump that is easy to transport, including a pump unit, a motor, a base 1, and a protection box 2. The pump unit and the motor are integrally assembled with the base 1 in a combined form;

[0036] In order to facilitate shipment, the inner wall of the base 1 is provided with a skid-mounted structure for skidding. The skid-mounted structure includes two groups of rectangular through holes 3, which are distributed left and right and sequentially arranged on the inner wall of the base 1. The front and rear ends of the two groups of rectangular through holes 3 are respectively connected with the front wall and the rear wall of the base 1. Through the two groups of rectangular through holes 3, hoisting equipment or forklift equipment can be used for skidding and transportation;

[0037] In order to prevent the device from being displaced due to vibration during use, the lower wall of the base 1 is provided with a through slot 4 which runs through from left to right, and the lower wall of the base 1 and the front and rear sides of the through slot 4 are provided with anti-skid structures, which include four sets of anti-skid pads 101, which are fixedly connected to the lower wall of the base 1 and close to the four corners of the lower wall of the base 1 respectively, and the four sets of anti-skid pads 101 are all made of weather-resistant rubber. The four sets of anti-skid pads 101 can prevent displacement due to vibration during use, and the anti-skid pads 101 made of weather-resistant rubber have good oxidation resistance and effectively improve the service life;

[0038] In order to facilitate short-distance movement at the construction site, a mobile body 5 is provided on the inner side wall of the through slot 4, and a walking structure for driving the mobile body 5 to walk is provided on the lower wall of the mobile body 5. The walking structure includes four sets of driving wheels 8, which are all arranged on the lower wall of the mobile body 5 and close to the four corners of the lower wall of the mobile body 5. The four sets of driving wheels 8 are all hub motors and the two sets of driving wheels 8 on the left side are steered by the electric hole steering device. When the base 1 is lifted off the ground by the support plate 6, it can be driven and transferred by the four sets of driving wheels 8, which can be conveniently moved for short distances at the construction site without human power, which is safer and more labor-saving.

[0039] In order to avoid the sideways rollover when the support plate 6 lifts up the base 1 due to the incomplete movement, a positioning structure for positioning is provided between the mobile body 5 and the base 1. The positioning structure includes a stopper 10 and two groups of proximity switches 11. The stopper 10 is fixedly connected to the inner upper wall of the through slot 4 and is located near the right end of the through slot 4. The two groups of proximity switches 11 are distributed front and back and are fixedly connected to the right end of the mobile body 5 in sequence. When the ends of the two groups of proximity switches 11 away from the mobile body 5 abut against the left wall of the stopper 10, the left end of the mobile body 5 is aligned with the left end of the base 1. When the mobile body 5 moves into the through slot 4, the position is confirmed by the abutment of the proximity switch 11 against the stopper 10. After the position is confirmed, the driving wheel 8 is locked. At this time, the lifting center of the support plate 6 coincides with the center of gravity of the base 1, and the sideways rollover will not occur, which effectively improves the safety.

[0040] In order to facilitate lifting the base 1, the upper wall of the mobile body 5 is provided with a support plate 6 through a lifting drive structure. The lifting drive structure includes a plurality of groups of second electric telescopic rods 19, and the plurality of groups of second electric telescopic rods 19 are fixedly connected to the inner wall of the mobile body 5.

The support plate 6 is driven to descend and ascend by the extension shafts of the plurality of second electric telescopic rods 19. In the initial state, the extension shafts of the second electric telescopic rods 19 are in a retracted state, and the lower wall of the support plate 6 abuts against the upper wall of the mobile body 5. When the mobile body 5 moves to a specified position inside the through groove 4, the extension shafts of the second electric telescopic rods 19 extend, driving the support plate 6 to rise, and lifting the base 1 until the base 1 is lifted off the ground by a certain distance. At this time, when the support plate 6 and the base 1 are locked by the anti-drop pin 12, the driving wheel 8 of the lower wall of the movable body 5 rotates to drive the base 1 position. After moving to the set position, the extension shafts of the second electric telescopic rods 19 are retracted, driving the support plate 6 and the base 1 to descend until the lower wall of the base 1 falls to the ground.

[0041] In order to move the vehicle body 5 into the through slot 4, a guide structure for guiding the vehicle body 5 to enter the through slot 4 is provided between the support plate 6 and the inner upper wall of the through slot 4. The guide structure includes a guide slot 7 and a plurality of rollers 18. The plurality of rollers 18 are respectively connected to the upper wall of the support plate 6 by a group of rotating shafts 17 in a left-right distribution and are rotatably connected in sequence. The plurality of rollers 18 are all located in the middle of the front-to-back direction of the support plate 6. The guide slot 7 is provided on the inner upper wall of the through slot 4 and is located in the middle of the front-to-back direction of the through slot 4. A trumpet-shaped opening is provided at the left end of the guide slot 7. The width of the guide slot 7 in the front-to-back direction coincides with the outer diameter of the rollers 18. When the vehicle body 5 enters the through slot 4, the plurality of rollers 18 enter the guide slot 7 for guidance, ensuring that the center line of the front-to-back direction of the vehicle body 5 coincides with the top projection of the center line of the front-to-back direction of the through slot 4, so as to cooperate with the positioning structure to fix the lifting center of the support plate 6.

[0042] In order to prevent sliding displacement between the moving body 5 and the moving base 1 when the moving body 5 moves, a locking structure for connecting the support plate 6 and the base 1 is provided between the support plate 6 and the inner wall of the through groove 4, and the locking structure includes four groups of anti-dropping pins 12 and anti-dropping holes 13. The four groups of anti-dropping holes 13 are arranged in pairs of two on the inner front wall and the inner rear wall of the through groove 4, and the four groups of anti-dropping pins 12 are slidably connected to the front wall and the rear wall of the support plate 6 in pairs of two. The outer diameter of the anti-dropping pins 12 is consistent with the inner diameter of the anti-dropping holes 13. A group of sink grooves 601 are respectively provided on the upper wall of the support plate 6 and near the four corners. The ends of the four groups of anti-dropping pins 12 facing the center position in the front and rear directions of the support plate 6 respectively penetrate the inner wall of the support plate 6 and extend into the four groups of sink grooves 601 respectively. The anti-dropping pins 12 extend into the sink grooves A first electric telescopic rod 16 is fixedly connected between one end of the groove 601 and the inner wall of the sink groove 601. When the upper wall of the support plate 6 abuts against the inner upper wall of the through groove 4, the horizontal height of the anti-dropping pin 12 is consistent with the horizontal height of the anti-dropping hole 13. When the left end of the mobile body 5 is aligned with the left end of the base 1, the anti-dropping pin 12 and the corresponding anti-dropping hole 13 are coaxial in the top view. When the upper wall of the support plate 6 abuts against the inner upper wall of the through groove 4, the first electric telescopic rod 16 extends the shaft to drive the anti-dropping pin 12 to insert into the anti-dropping hole 13. The support plate 6 and the base 1 are fixed by four groups of anti-dropping pins 12 to avoid displacement during transportation. After the anti-dropping pin 12 is separated from the anti-dropping hole 13, the mobile body 5 can be driven out of the through groove 4 and used as a separate transportation vehicle, thereby improving functionality.

[0043] In order to facilitate outdoor movement, a power supply structure for power supply is provided on the lower wall of the mobile body 5, and the power supply structure includes a cover plate 9, a battery box 901 and a battery pack 15. A battery compartment penetrating the lower wall of the mobile body 5 is provided inside the mobile body 5, and the cover plate 9 is fixedly connected to the lower opening of the battery compartment, and the battery box 901 is fixedly connected to the upper wall of the cover plate 9.

The walking structure, positioning structure, lifting drive structure and locking structure are all electrically connected to the power supply structure. Power is supplied by the battery pack 15, so that the walking structure, positioning structure, lifting drive structure and locking structure can all be used outdoors.

[0044] Working principle: Two groups of rectangular through holes 3 are distributed on the left and right sides and are arranged in sequence on the inner wall of the base 1. The front and rear ends of the two groups of rectangular through holes 3 are respectively connected with the front wall and the rear wall of the base 1. Through the two groups of rectangular through holes 3, lifting equipment or forklift equipment can be used for prying and transportation. The four groups of anti-skid pads 101 are all weather-resistant rubber. The four groups of anti-skid pads 101 can prevent displacement due to vibration during use. The anti-skid pads 101 made of weather-resistant rubber have good oxidation resistance and effectively improve the service life. When the base 1 is lifted off the ground by the support plate 6, it can be driven and transferred by the four groups of driving wheels 8, which can be more conveniently moved on the construction site. The vehicle body 5 can be moved in a short distance without human effort, which is safer and more labor-saving. When the vehicle body 5 moves into the through slot 4, the proximity switch 11 abuts against the block 10 to confirm the position. After the position is confirmed, the driving wheel 8 is locked. At this time, the lifting center of the support plate 6 coincides with the center of gravity of the base 1, and no rollover will occur, which effectively improves safety. In the initial state, the extension shaft of the second electric telescopic rod 19 is in a retracted state, and the lower wall of the support plate 6 abuts against the upper wall of the vehicle body 5. When the vehicle body 5 moves to the specified position inside the through slot 4, the extension shaft of the second electric telescopic rod 19 extends, driving the support plate 6 to rise, and the top The base 1 is lifted until it is lifted a certain distance from the ground. At this time, when the support plate 6 and the base 1 are locked by the anti-drop pin 12, the driving wheel 8 of the lower wall of the movable body 5 rotates to drive the base 1 to move to the set position, and the second electric telescopic rod 19 extends the shaft and retracts, driving the support plate 6 and the base 1 to fall until the lower wall of the base 1 falls to the ground. When the movable body 5 enters the interior of the through groove 4, it is guided by multiple groups of rollers 18 into the guide groove 7 to ensure that the center line of the front and rear directions of the movable body 5 coincides with the center line of the front and rear directions of the through groove 4 in the overhead projection, so as to cooperate with the positioning structure to fix the lifting center of the support plate 6, and the upper wall of the support plate 6 When abutting against the inner upper wall of the through slot 4, the first electric telescopic rod 16 extends the shaft, driving the anti-dropout pin 12 to insert into the anti-dropout hole 13, and the pallet 6 and the base 1 are fixed by four groups of anti-dropout pins 12 to avoid displacement during transportation, and after the anti-dropout pins 12 are separated from the anti-dropout holes 13, the mobile body 5 can be driven out of the through slot 4 and used as a separate transfer vehicle, which improves the functionality. The walking structure, positioning structure, lifting drive structure and locking structure are all electrically connected to the power supply structure, and are powered by the battery pack 15, so that the walking structure, positioning structure, lifting drive structure and locking structure can all be used outdoors.
