[0028] 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.

[0029] A diesel engine matching hose performance testing device, such as Figure 1 As shown, it includes a base 1, a group of left-right symmetrical anti-slip feet 2 are fixedly connected to the bottom end of the base 1, a mounting groove 3 is opened at the top of the base 1, and sliding grooves 4 are opened on both sides of the base 1 away from the mounting groove 3, an adjusting mechanism 5 is movably connected inside the mounting groove 3, and a group of left-right symmetrical support plates 6 are fixedly connected to the top of the adjusting mechanism 5, and a blower 7 is fixedly connected to the outer wall of one of the support plates 6; a group of left-right symmetrical connecting pipes 8 are fixedly connected to the inner wall of the support plate 6, and a protrusion 9 is fixedly connected to the outer wall of the connecting pipe 8, one side of one of the connecting pipes 8 is fixedly connected to the output end of the blower 7, and a barometer 10 is fixedly connected to the top of one side of the other connecting pipe 8, a fixing mechanism 11 is fixedly connected to the inner wall of the support plate 6, and an auxiliary mechanism 12 is fixedly connected to the top of the fixing mechanism 11.

[0030] First, after placing the middle section of the hose inside the support plate 1203, the two sides of the hose can be sleeved on the connecting pipe 8. After that, the adjusting mechanism 5 can be controlled to adjust the distance between the supporting plates 6 according to the length of the hose. At this time, the fixing mechanism 11 can be controlled to seal and fix the two sides of the hose. At the same time, the blower 7 is controlled to operate, and the blower 7 will inflate the inside of the hose through the connecting pipe 8. When the gas reaches a certain amount, the inflation can be stopped. At this time, the personnel can observe whether the value on the pressure gauge 10 is reduced, so as to detect the air tightness of the hose. After detecting the air tightness, the adjusting mechanism 5 can be controlled to pull the hose on both sides to detect the quality of the hose.

[0031] like Figure 3-4As shown, the fixing mechanism 11 includes a motor 1101, a fixing column 1102, a gear 1103, a gear ring 1104, a transmission rod 1105 and a fixing plate 1106. The output end of the motor 1101 is fixedly connected to the axis of the gear 1103, the gear ring 1104 is fixedly connected to the outer wall of the fixing column 1102, the outer wall of the gear ring 1104 is provided with an arc groove, and one end of the transmission rod 1105 is slidably connected to the inside of the arc groove, and the other end of the transmission rod 1105 extends to the inner side of the fixing column 1102. The fixing plate 1106 is fixedly connected to the fixing column 1102, and the fixing column 1102 is fixedly connected to the inner wall of the supporting plate 6. The gear 1103 is meshed with the gear ring 1104, and the gear 1103 is movably connected to the bottom of the gear ring 1104. The motor 1101 is fixedly connected to the inside of the supporting plate 6. The inner wall of the fixing plate 1106 is provided with a card slot 13, and the card slot 13 is meshed with the protrusion 9. The connecting pipe 8 is fixedly connected to the opposite side of the inside of the fixing column 1102, and the gear ring 1104 is rotatably connected to the outer wall of the fixing column 1102.

[0032] Control motor 1101 to operate. When motor 1101 operates, it will drive the gear ring 1104 to rotate through gear 1103. When the gear ring 1104 rotates, it will drive the transmission rods 1105 to approach each other through the arc groove. When the transmission rods 1105 approach each other, they will drive the fixed plates 1106 to move synchronously. At this time, the rubber tube will be slightly deformed by the groove 13 on the fixed plate 1106, so that it fits on the protrusion 9, so as to prevent internal gas leakage, thereby improving the accuracy of the detection data.

[0033] like Figure 2-6 As shown, the adjustment mechanism 5 includes a second motor 501, a worm 502, a worm wheel 503, a bidirectional screw 504, a slider 505, a slide rail 506 and an adjustment plate 507. The second motor 501 is fixedly connected to one end of the worm 502, the worm wheel 503 is movably connected to the outer wall of the worm 502, the worm wheel 503 is fixedly connected to the middle section of the bidirectional screw 504, the worm wheel 503 is meshed with the worm 502, and the slide rail 506 is provided with two front-to-back symmetrical ones. The slider 505 is slidably connected to the top of the slide rail 506, the slide rail 506 is fixedly connected to the inside of the slide groove 4, the bidirectional screw 504 is rotatably connected to the inside of the mounting groove 3, the bottom end of the adjustment plate 507 is threadedly connected to the bidirectional screw 504, the second motor 501 is fixedly connected to the inside of the mounting groove 3, and the bottom end of the adjustment plate 507 is fixedly connected to the top of the slider 505 on both sides.

[0034] After both sides of the hose are sleeved on the connecting pipe 8, the motor 2 501 can be controlled to rotate. When the motor 2 501 rotates, the worm gear 503 is driven to rotate through the worm 502. When the worm gear 503 rotates, the bidirectional screw 504 is driven to rotate. At this time, the screw can drive the adjustment plates 507 to move away from or closer to each other, and the support plates 6 will also move synchronously. At this time, the distance between the support plates 6 can be adjusted according to the length of the hose, thereby improving the applicability of the equipment and making it more convenient for personnel to operate. At the same time, the support plates 6 can be continuously controlled to move away to detect the pulling force that the hose can withstand.

[0035] like Figure 2-5 As shown, the auxiliary mechanism 12 includes a telescopic plate 1201, an electric push rod 1202, a support plate 1203, a spring 1204 and a telescopic rod 1205. The top end of the spring 1204 is fixedly connected to the bottom end of the telescopic plate 1201, and the bottom end of the spring 1204 is fixedly connected to the top end of the support plate 1203. The output end of the electric push rod 1202 is fixedly connected to the top end of the support plate 1203, and the fixed end of the electric push rod 1202 is fixedly connected to the top end of the telescopic plate 1201. The telescopic rod 1205 is fixedly connected to the opposite side of the spring 1204. Both sides of the bottom end of the telescopic plate 1201 are fixedly connected to the outer wall of the fixed column 1102. The spring 1204 is provided with two left-right symmetrical ones.

[0036] During the inspection of the hose, the electric push rod 1202 can be controlled to move, and the electric push rod 1202 can drive the support plate 1203 to move up and down. At this time, the support plate 1203 will drive the middle section of the hose to remain parallel to the two sides of the hose, thereby preventing the pipe from falling off due to gravity pulling on both ends, and at the same time reducing the impact on the inspection data.

[0037] Here’s how it works:

[0038] When in use, after the two sides of the hose are sleeved on the connecting pipe 8, the motor 2 501 can be controlled to rotate. When the motor 2 501 rotates, the worm wheel 503 is driven to rotate through the worm 502. When the worm wheel 503 rotates, the bidirectional screw 504 is driven to rotate. At this time, the screw can drive the adjustment plates 507 to move away from or closer to each other, and the support plates 6 will also move synchronously. At this time, the distance between the support plates 6 can be adjusted according to the length of the hose, so as to improve the applicability of the equipment and make it more convenient for personnel to operate. At the same time, the support plates 6 can be continuously controlled to move away to detect the pulling force that the hose can withstand. After that, the motor 1 1101 can be controlled to operate. When the motor 1 1101 operates, it will drive the gear ring 1104 through the gear 1103. When the gear ring 1104 rotates, the transmission rods 1105 are driven to approach each other through the arc groove. When the transmission rods 1105 approach each other, the fixed plates 1106 are driven to move synchronously. At this time, the rubber tube is slightly deformed by the slot 13 on the fixed plate 1106, so that it fits on the protrusion 9 to prevent internal gas leakage, thereby improving the accuracy of the detection data. During the detection of the hose, the electric push rod 1202 can be controlled to move, and the electric push rod 1202 can drive the support plate 1203 to move up and down. At this time, the support plate 1203 will drive the middle section of the hose to remain parallel to the two sides of the hose, thereby preventing the pipe from falling off at both ends due to gravity pulling, and at the same time reducing the impact on the detection data.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
