[0033] Reference Figures 1-7A hydraulic gate hoist testing device includes a base 1. A clearance hole 2 is provided on one side of the base 1. Auxiliary feeding components 3 are provided between the inner walls of both sides of the clearance hole 2 and on one side of the base 1 to transport the hydraulic gate hoist onto the base 1. A clamping component 4 for fixing the hydraulic gate hoist is provided between the two auxiliary feeding components 3. A testing component 5 for performing functional tests on the hydraulic gate hoist is provided on the top of the base 1. A function conversion component 6 for changing the test items of the testing component 5 is provided on one side of the testing component 5. In use, the hydraulic gate hoist is transported from the ground to the base 1 through the auxiliary feeding components 3, and then the clamping component 4 is used to fix the hydraulic gate hoist. After fixing, the testing component 5 is used for testing. After each test is completed, the function conversion component 6 is used to change the test items of the testing component 5, thereby completing two tests in one unit. This reduces the space occupied by the device and eliminates the need to move the hydraulic gate hoist during testing, improving the convenience of the device's testing.

[0034] Each of the two auxiliary feeding components 3 includes a rotating rod 301. The two rotating rods 301 are rotatably connected between the inner walls of the two sides of the clearance hole 2 and one side of the base 1, respectively. A connecting shaft 308 is bolted between the two rotating rods 301, allowing the two rotating rods 301 to rotate simultaneously. A connecting rod 307 is bolted between the two sliding rods 302, allowing the two sliding rods 302 to slide simultaneously. A sliding rod 302 is slidably connected to the top of each of the two rotating rods 301. A groove 303 is provided at the top of the sliding rod 302, and the bottom is an inclined surface 304. A slider 305 is slidably connected to the inner wall of the bottom of the groove 303. A rotating groove 309 is provided at one end of each of the two sliding rods 302. A fixed shaft 310 is rotatably connected between the inner walls of the two sides of the rotating groove 309. A support plate 306 is keyed to the outer circumference of the fixed shaft 310. A welded outer wall on one side of the fixed shaft 310 is... A torsion spring 311 is provided, with its other end fixed to the rotating groove 309. When the hydraulic hoist needs to be transported to the base 1, the rotating rod 301 is rotated, thereby driving the slide rod 302 to rotate synchronously. Then, the slide rod 302 slides down from above the rotating rod 301, making the inclined surface 304 contact the ground. Then, the support plate 306 is rotated, making the support plate 306 level with the top of the inclined slide rod 302. Then, the hydraulic hoist is placed above the slider 305, and then the slider 305 is slid, making the slider 305 contact the other end of the groove 303. Then, the slide rod 302 is slid, making both ends of the slide rod 302 level with the rotating rod 301. When the support plate 306 contacts the ground, the torsion spring 311, which has been twisted and deformed, will drive the support plate 306 to return to its original position, thereby enabling the support plate 306 to support one end of the slide rod 302, improving the stability of the slide rod 302.

[0035] The clamping assembly 4 includes a connecting plate 401, which is fixed to the top of the base 1 by bolts. A first clamping block 402 is detachably connected to the top of one end of the connecting plate 401 by bolts. A slot 408 is provided on one side of the connecting plate 401, and a plug 407 is inserted into the slot 408. A second clamping block 404 is integrally formed on the top of the plug 407. Arc-shaped grooves 403 are provided on opposite sides of the first clamping block 402 and the second clamping block 404. A limiting assembly is provided on one side of the connecting plate 401 to limit the position of the plug 407. When the hydraulic gate opener is delivered by the slider 305, the hydraulic gate opener will contact the arc-shaped groove 403, and then the plug 407 at the bottom of the second clamping block 404 will be inserted into the slot 408. The limiting assembly will then limit the position of the second clamping block 404, thereby completing the fixation of the hydraulic gate opener and making the testing of the hydraulic gate opener more accurate.

[0036] The limiting component includes a baffle 405, which is slidably connected to one side of the connecting plate 401. Two first springs 406 are welded to the bottom of the baffle 405, and the other end of the first springs 406 is fixed to the base 1. When the insert 407 is inserted into the slot 408, the baffle 405 is slid down to expose the slot 408. Then the insert 407 is inserted into the slot 408. At this time, the baffle 405 is released, and the baffle 405 is pushed upward by the first springs 406 at the bottom, which are compressed and deformed, thereby blocking the slot 408 and preventing the insert 407 from sliding out of the slot 408, thus improving the stability of the second clamping block 404.

[0037] The test component 5 includes two guide rails 502, both of which are bolted to the top of the base 1. A movable seat 503 is slidably connected to the outer walls of the two guide rails 502 on multiple sides. Two support blocks 510 are welded to both sides of the movable seat 503, and these support blocks 510 are symmetrically distributed to provide auxiliary support for the movable seat 503, making its center of gravity more stable. A through hole is provided on one side of the movable seat 503, and a sliding column 505 is slidably connected within the through hole. Retaining rings 506 are welded to the outer circumference of both ends of the sliding column 505, and a hook 511 is threaded onto one side of the sliding column 505. Multiple scales 507 are provided on the outer circumference of the sliding column 505. A strong spring 504 is bolted to one side of the movable seat 503, and the other end of the strong spring 504 is fixed to one of the retaining rings 506. Rotating plates 508 are rotatably connected to both sides of the movable seat 503. Two symmetrically distributed plates are bolted to the top of the base 1. The positioning block 509 is fixed to the top of the base 1 by bolts, and the piston end of the hydraulic cylinder 501 is fixed to the moving seat 503. After the hydraulic gate hoist is installed, the hook 511 is connected to the moving end of the hydraulic gate hoist, and the hydraulic gate hoist is started to retract, so that the hook 511 pulls the slide column 505 to slide in the through hole. The value of the scale 507 on the slide column 505 on the side beyond the moving seat 503 can be read. The sliding of the slide column 505 will cause the strong spring 504 to contract and generate a strong elastic force. Through the action of the strong spring 504, the more the moving end of the hydraulic gate hoist retracts, the greater the elastic force of the strong spring 504, thus completing the opening and closing force test of the hydraulic gate hoist. The moving seat 503 can be moved through the function conversion component 6, and the hydraulic cylinder 501 is started. The hydraulic cylinder 501 will cause the moving seat 503 to move, thus completing the load performance test of the hydraulic gate hoist.

[0038] The function conversion component 6 includes an electric push rod 601, which is fixed to one side of the movable seat 503 by bolts. The movable end of the electric push rod 601 is fixed to a connecting block 602 by bolts. The bottom of the connecting block 602 has a groove 603. Both sides of the connecting block 602 are rotatably connected to force arms 604. When the electric push rod 601 is activated, it drives the connecting block 602 to move downward, thereby causing the groove 603 to lock one of the retaining rings 506, thus fixing the position of the sliding column 505. The downward movement of the connecting block 602 also compresses the force arm 604, causing the force arm 604 to compress the rotating plate 508, thereby causing the rotating plate 508 to rotate, thus causing the positioning block 509 to disengage from the rotating plate 508. The device can automatically switch the test items according to the requirements, improving the applicability of the device.

[0039] The working principle of this invention is as follows: First, rotate the rotating rod 301, causing the sliding rod 302 to rotate synchronously. Then, the sliding rod 302 slides down from above the rotating rod 301, causing the inclined surface 304 to contact the ground. Next, rotate the support plate 306 until it is level with the top of the inclined sliding rod 302. Then, place the hydraulic gate opener above the slider 305. Next, slide the slider 305 until it contacts the other end of the slide groove 303. Finally, slide the sliding rod 302 until both ends of the sliding rod 302 are flush with the rotating rod 301. At this point, the hydraulic gate opener will contact the arc-shaped groove 403, slide the baffle 405 downward to expose the slot 408, and then insert the insert 407 at the bottom of the second clamping block 404 into the slot 408. Releasing the baffle 405 will cause it to be pushed upward by the first spring 406, which is compressed and deformed at the bottom, thus blocking the slot 408 and preventing the insert 407 from sliding out. This completes the fixing of the hydraulic gate opener. The hook 511 is then connected to the moving end of the hydraulic gate opener, and the hydraulic gate opener is activated to retract, causing the hook 511 to pull. The movable slide column 505 slides within the through hole, allowing readings to be taken from the side of the scale 507 on the slide column 505 that extends beyond the moving seat 503. The sliding of the slide column 505 causes the powerful spring 504 to contract, generating a strong elastic force. The more the moving end of the hydraulic gate opener contracts through the force of the powerful spring 504, the greater the elastic force of the powerful spring 504, thus completing the opening and closing force test of the hydraulic gate opener. Activating the electric push rod 601 causes the connecting block 602 to move downwards, thereby causing the groove 603 to engage one of the retaining rings 506. The position of the sliding column 505 is then fixed. The downward movement of the connecting block 602 will also compress the lever arm 604, causing the lever arm 604 to compress the rotating plate 508, thereby causing the rotating plate 508 to rotate. This will cause the positioning block 509 to disengage from the rotating plate 508. Then, the hydraulic cylinder 501 is activated, which will cause the moving seat 503 to move, thereby completing the load performance test of the hydraulic gate hoist. The two tests are combined into one, making the space occupied by the equipment small. At the same time, there is no need to move the hydraulic gate hoist during the test, which improves the convenience of device testing.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
