Description

Technical Field

[0001] The invention relates to the technical field of testing devices, in particular to a bending and compression resistance testing device used for processing high-performance composite hoses for marine engineering. Background Art

[0002] Composite hoses have excellent performance in corrosive environments, such as sulfuric acid, nitric acid, and flammable and explosive solvents. They remain resistant to rupture and leakage even in the harshest environments, preventing sudden bursts. They can easily handle the transmission of gasoline, diesel, crude oil, and a variety of chemical liquids, and even maintain high flexibility in cold weather. Therefore, composite hoses are frequently used in marine engineering. After processing, composite hoses require internal testing for compression and bending resistance. This is typically done by filling the hose with water and then using a pressure gauge at the water inlet to test the hose's compression resistance. Leakage is also monitored to determine the hose's compression resistance.

[0003] Since the existing water filling method is to fix the flange on the composite hose on the water inlet pipe and the water outlet pipe, and then test the water filling, the flange fixing the composite hose is difficult to disassemble and install, which greatly reduces the detection efficiency of the composite hose. In addition, when filling with water and measuring the pressure, the bending resistance of the composite hose cannot be tested. If the hose is bent after the water is released, its bending resistance in the working state cannot be tested. Direct water filling testing is not convenient for bending the composite hose. When the water in the composite hose needs to be released after the test is completed, some water will remain in the composite hose, which will affect the subsequent transportation.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figure 1 、 Figure 4 and Figure 5 As shown, the present invention relates to a bending and compression resistance testing device for processing high-performance composite hoses for marine engineering, comprising two fixing frames 1, a fixing structure 2 being installed on the fixing frames 1, a resistance structure 3 being installed on the fixing frames 1, a lifting structure 4 being installed between the two fixing frames 1, a transmission structure 5 being installed at the bottom end of the lifting structure 4, a rotating structure 6 being installed between the fixing frames 1 and the fixing structure 2, and a sealing structure 7 being installed on the fixing structure 2.

[0032] Specifically, such as Figure 1 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, the fixed structure 2 includes a fixed disk 201, and the tops of the two fixed frames 1 are rotatably connected to the fixed disk 201, and the fixed disk 201 is fixedly connected to the fixed shaft 202 in a circular array distribution relationship, and the fixed shaft 202 is rotatably connected to the clamping rod 203, and the fixed disk 201 is fixedly connected to the fixed seat 204, and a spring 205 is fixedly connected between the clamping rod 203 and the fixed seat 204, and the fixed seat 204 is fixedly connected to the positioning rod 206, one of the fixed disks 201 is fixedly connected to the water inlet pipe 207, and the other fixed disk 201 is fixedly connected to the water outlet pipe 208, and the fixed disk 201 is fixedly connected to the positioning column 209, and the positioning column 209 is distributed in a circular array with a plurality of One end of the hose is placed on the side end of the fixed disk 201. When the flange of the composite hose and the clamping rod 203 collide, since the side end of the clamping rod 203 is arc-shaped, it can drive multiple clamping rods 203 to rotate outward. When the flange and the positioning column 209 are plugged in, the flange can be positioned to prevent rotation. Then, multiple clamping rods 203 drive the clamping rod 203 to reset through the elastic force of multiple springs 205. Through the collision of multiple clamping rods 203 and the flange, the flange can be quickly fixed, so that the composite hose can be quickly fixed. Then, the other end of the composite hose is fixed on another fixed disk 201, so that the composite hose can be fixed. Then, the composite hose is filled with water through the water inlet pipe 207 for pressure testing, and water is discharged through the water outlet pipe 208.

[0033] Specifically, such as Figure 5 and Figure 7 As shown, the interference structure 3 includes a rotating ring 301, and the rotating ring 301 is rotatably connected to the fixed disk 201. A plurality of positioning rings 302 are fixedly connected in a circular array distribution relationship inside the rotating ring 301. The positioning ring 302 and the clamping rod 203 interfere with each other. A plurality of positioning blocks 303 are fixedly connected in a circular array distribution relationship on the fixed disk 201. The positioning ring 302 and the positioning block 303 are slidingly connected. A limiting block 304 is fixedly connected to the positioning block 303. The limiting block 304 interferes with the positioning ring 302. Rotating the rotating ring 301 can drive the positioning ring 302 to rotate on the positioning block 303. When the positioning ring 302 interferes with the clamping rod 203, the clamping rod 203 can be driven to rotate. After the plurality of clamping rods 203 and the flange on the composite hose no longer interfere with each other, the composite hose can be removed, and the positioning ring 302 can be limited by the limiting block 304.

[0034] Specifically, such as Figure 1 and Figure 2As shown, the lifting structure 4 includes a cross bar 401, and the cross bar 401 is fixedly connected between the two fixing frames 1. A plurality of sliding bars 402 are slidably connected to the cross bar 401. The top of the sliding bar 402 is fixedly connected to a push rod 403, and the top of the push rod 403 is fixedly connected to a plurality of arc-shaped arc plates 404. The sliding bar 402 can drive the arc plates 404 fixed on the push rod 403 to slide up and down, thereby driving the composite hose placed on the arc plates 404 to bend up and down, so that the bending resistance of the composite hose can be tested when the pressure resistance of the composite hose is tested.

[0035] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the transmission structure 5 includes a bottom rod 501, which is fixedly connected between the two fixed frames 1. A slider 502 is slidably connected inside the bottom rod 501, and a resistance block 503 is fixedly connected to the top of the slider 502. The bottom end of the slide bar 402 is fixedly connected to a resistance rod 504, and a resistance wheel 505 is rotatably connected to the resistance rod 504. The resistance block 503 and the resistance wheel 505 are in conflict. A reciprocating screw rod 506 is rotatably connected to the bottom rod 501. The reciprocating screw rod 506 6 is threadedly connected to the slider 502, and a motor 507 is installed on the side end of the fixed frame 1. The output end of the motor 507 is fixedly connected to the reciprocating screw 506. By starting the motor 507, the reciprocating screw 506 can be driven to rotate, thereby driving the slider 502 to slide back and forth inside the bottom rod 501, thereby driving the interference block 503 to slide. When the interference block 503 and the interference wheel 505 conflict, since the interference block 503 is an inclined structure as a whole, it can drive the interference rod 504 to slide upward.

[0036] Specifically, such as Figure 4 As shown, the rotating structure 6 includes a rotating shaft 601, the top end of the fixing frame 1 is fixedly connected to the rotating shaft 601, the bottom end of the fixing plate 201 is fixedly connected to the rotating rod 602, the rotating rod 602 and the rotating shaft 601 are rotatably connected, and both ends of the fixing frame 1 are fixedly connected to the limiting plates 603, and the rotating rod 602 and the limiting plates 603 are in conflict. When the arc plate 404 drives multiple parts of the composite hose to move up and down, the fixing plate 201 is rotatably connected to the fixing frame 1 through the rotating shaft 601 and the rotating rod 602, so that the composite hose can be slightly tilted, and the junction of the composite hose and the flange is protected. The limiting plate 603 and the rotating rod 602 are in conflict, so the rotation angle of the fixing plate 201 can be limited.

[0037] Specifically, such as Figure 5 and Figure 6As shown, the sealing structure 7 includes a sealing plate 701, and the side end of the water outlet pipe 208 is detachably connected to the sealing plate 701, and a plurality of clamping rods 702 are fixedly connected to the sealing plate 701. The water outlet end of the water outlet pipe 208 is provided with a plurality of clamping grooves 703, and the clamping rods 702 and the clamping grooves 703 are engaged. A sealing plug 704 is fixedly connected to the sealing plate 701, and the sealing plug 704 and the water outlet pipe 208 are plugged in. When the water in the composite hose needs to be released, the sealing plate 701 is rotated. When the clamping rod 702 and the clamping groove 703 are separated, the sealing plug 704 can be pulled out, so that the water in the composite hose can be released through the water outlet pipe 208.

[0038] When the present invention is in use, when the composite hose needs to be tested, one end of the composite hose is placed on the side end of the fixed disk 201. When the flange of the composite hose and the clamping rod 203 collide, since the side end of the clamping rod 203 is in an arc shape, it can drive multiple clamping rods 203 to rotate outward. When the flange and the positioning column 209 are plugged in, the flange can be positioned to prevent rotation. Then, the multiple clamping rods 203 drive the clamping rods 203 to reset through the elastic force of multiple springs 205. The multiple clamping rods 203 collide with the flange, so that the flange can be quickly fixed. Therefore, the composite hose can be quickly fixed. Then, the other end of the composite hose is fixed on another fixed disk 201, so that the composite hose can be fixed. Then, The water inlet pipe 207 performs a pressure test on the composite hose when it is filled with water, and the water is released through the water outlet pipe 208. When the composite hose needs to be removed, the rotating ring 301 is rotated to drive the positioning ring 302 to rotate on the positioning block 303. When the positioning ring 302 conflicts with the clamping rod 203, the clamping rod 203 can be driven to rotate. After the multiple clamping rods 203 and the flanges on the composite hose no longer conflict, the composite hose can be removed. The positioning ring 302 can be limited by the limit block 304. When the composite hose is filled with water and its internal pressure resistance is observed, the reciprocating screw rod 506 can be driven to rotate by starting the motor 507, thereby driving the slider 502 to slide back and forth inside the bottom rod 501, thereby driving the conflict block 503 to slide When the friction block 503 and the friction wheel 505 collide, the friction block 503 is an inclined structure as a whole, so it can drive the friction rod 504 to slide upward, and the sliding rod 402 can drive the arc plate 404 fixed on the top rod 403 to slide up and down, thereby driving the composite hose placed on the arc plate 404 to bend up and down, so that when the pressure resistance of the composite hose is tested, the bending resistance of the composite hose can be tested, and when the friction block 503 continues to move, when the friction wheel 505 and the friction block 503 are separated, the arc plate 404 can be automatically reset by the gravity of the composite hose and the internal water, and by setting a plurality of arc plates 404, the bending resistance of the composite hose can be tested at multiple positions, and when the composite hose needs to be tested, When the water inside is released, the multiple curved plates 404 slide up and down, which can better release the water inside the composite hose and prevent water from remaining in the composite hose. When the curved plates 404 drive the composite hose to move up and down in multiple places, the fixed plate 201 is rotatably connected to the fixed frame 1 through the rotating shaft 601 and the rotating rod 602, so that the composite hose can be slightly tilted, and the junction of the composite hose and the flange is protected. The limiting plate 603 and the rotating rod 602 interfere with each other, so that the rotation angle of the fixed plate 201 can be limited. When the water in the composite hose needs to be released, the sealing plate 701 is rotated. When the clamping rod 702 and the clamping slot 703 are separated, the sealing plug 704 can be pulled out, so that the water in the composite hose can be released through the water outlet pipe 208.
