Description

Technical Field

[0001] This utility model relates to the field of pin shaft simulated underwater pressure testing technology, and in particular to a test fixture and a pin shaft simulated underwater pressure testing system. Background Technology

[0002] Currently, most hydropower station flat gates utilize hydraulic grab beams for underwater grabbing and lowering. The pin-threading device of the hydraulic grab beam is the connection between the gate and the grab beam. During prolonged use, due to malfunctions in the hydraulic pump station or the pin-threading device itself, the grab beam may fail to properly engage or disengage the pin after being lowered into the water. This necessitates dispatching divers to remove the pin, posing a potential hazard to the safe operation of the equipment.

[0003] To avoid the above problems, the grab beam pin is usually placed at the bottom of the water along with the grab beam, and the pressure bearing capacity of the grab beam pin is tested by water pressure. However, this test method requires a certain amount of time to obtain test data, and it can only be carried out when the unit is shut down, which will delay the working efficiency of the unit and affect the normal operation of the unit. Utility Model Content

[0013] In a preferred embodiment of the test fixture described in this utility model, the connecting hole is connected to the connecting piece by a connecting bolt.

[0014] The beneficial effects of this utility model are as follows: by setting up a pressing component to continuously press the pin, the pressure of the pin underwater can be simulated. This allows the test to be carried out without stopping the unit, thus avoiding delays in the normal operation of the unit. At the same time, the data of the pin under different pressures can be quickly obtained by adjusting the output power of the pressing component.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1

[0033] Reference Figures 1-6This is the first embodiment of the present invention, which provides a test fixture.

[0034] The pressing assembly 100 includes a connecting pipe 101, a moving rod 102 disposed on one side of the connecting pipe 101, and a push plate 103 disposed on one side of the moving rod 102. During the test, hydraulic oil needs to be supplied into the connecting pipe 101, so that the moving rod 102 pushes the push plate 103 to squeeze the pin, thereby simulating the pressure of the pin underwater. If the pin still maintains its original posture after the test, it means that the pin has the ability to work underwater. If the pin is displaced or changes its shape, it means that the pin is unqualified and needs to be replaced.

[0035] The clamping assembly 200 is disposed on the outer wall of the connecting pipe 101 and includes a first connecting plate 201, a horizontal plate 202 connected to the bottom of the first connecting plate 201, and a second connecting plate 203 connected to one side of the horizontal plate 202. A connecting piece 108 is installed on the outer wall of the connecting pipe 101. One side of the first connecting plate 201 is connected to the connecting piece 108 by bolts. A placement groove 205 is provided on the top of the first connecting plate 201. The outer wall of the moving rod 102 is slidably connected to the outer wall of the placement groove 205. Before conducting the test, the first connecting plate 201 and the connecting piece 108 need to be connected together by bolts. Then, the clamping assembly 200 is placed under the gripping beam, and the second connecting plate 203 is fixed to the gripping beam by bolts. This fixes the pressing assembly 100 to the gripping beam, thereby preventing the pressing assembly 100 from shifting during the test.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that this embodiment shows another form of the clamping component 200.

[0038] Specifically, the clamping assembly 200 also includes a fixed beam 206, a connecting hole 207 opened on one side of the fixed beam 206, a connecting post 208 provided on one side of the fixed beam 206, and a threaded hole 209 opened on the inner wall of the connecting post 208. The connecting hole 207 is connected to the connecting piece 108 by connecting bolts. In some cases, the clamping beam is too large to lift and cannot be clamped by the clamping assembly 200 in Embodiment 1. In this case, the clamping assembly 200 can be replaced and the clamping assembly 200 in this embodiment can be used for fixing.

[0039] During the fixing process, the fixing beam 206 is installed onto the connecting piece 108, then the connecting post 208 is attached to the gripping beam, and finally the gripping beam and the connecting hole 207 are connected by bolts. The connecting hole 207 is threaded and can be directly connected to the bolts. This allows the fixing beam 206 and the pressing assembly 100 to be quickly fixed in the designated position without moving or lifting the gripping beam.

[0040] Example 3

[0041] Reference Figures 1 to 7 This is the third embodiment of the present invention, which includes a pin shaft simulation underwater pressure test system for providing power to the pressing assembly 100.

[0042] Specifically, a first connector 104 is provided at the top of the connecting pipe 101, a second connector 106 is connected to one side of the connecting pipe 101, a first delivery pipe 105 is connected to one side of the first connector 104, and a second delivery pipe 107 is connected to one side of the second connector 106. Both the first delivery pipe 105 and the second delivery pipe 107 are hoses specifically designed for delivering hydraulic oil.

[0043] The hydraulic assembly 300 is interconnected with the pressing assembly 100 via pipes. It includes a base 301, a control valve 302 mounted on top of the base 301, a hydraulic gauge 305 mounted on top of the base 301, and a motor 306 mounted on top of the base 301. One side of the control valve 302 is connected to the hydraulic gauge 305 via a pipe. A third connector 303 is provided on one side of the control valve 302, and a fourth connector 304 is also provided on the same side of the control valve 302. The third connector 303... The fourth connector 304 is connected to the other end of the first delivery pipe 105 and the second delivery pipe 107 respectively. When power is needed to supply power to the pressing assembly 100, hydraulic oil and a hydraulic pump are stored in the base 301. The motor 306 is connected to the hydraulic pump. When the motor 306 is started, it will deliver hydraulic oil to the control valve 302. The third connector 303 is opened through the control valve 302, and the hydraulic oil will be delivered from the first delivery pipe 105 to the pressing assembly 100, so that the pressing assembly 100 can perform the pressing operation.

[0044] It should be noted that when the third connector 303 is open, the fourth connector 304 needs to be closed. When the pressing work is no longer performed, the third connector 303 needs to be closed, the fourth connector 304 needs to be opened, and the motor 306 needs to be controlled to reverse the hydraulic oil in the pressing assembly 100 so that the pressing assembly 100 no longer squeezes the pin.
