Description

Technical Field

[0001] The present invention relates to the field of fluid charging and discharging equipment, in particular to an air charging module comprising an air pipe joint, which can be used in the charging and discharging of an energy storage device of a hydraulic pile hammer. Background Art

[0002] Patent document CN104912854A describes a single-valve gas-liquid hydraulic pile hammer, which includes an oil distribution tank, a single-spool two-position three-way electro-hydraulic reversing valve, an air storage tank, a dual-medium hydraulic cylinder, three high-pressure accumulators, three low-pressure accumulators, two oil-conducting steel pipes, and an air distribution tank. The high-pressure accumulator is connected to the hydraulic system's high-pressure inlet oil circuit, and its internal pressure must match the hydraulic system's inlet pressure; the low-pressure accumulator is connected to the hydraulic system's low-pressure return oil circuit, and its internal pressure must match the hydraulic system's return pressure. Mismatches between the high-pressure accumulator and the hydraulic system's inlet pressure, or between the low-pressure accumulator and the hydraulic system's return pressure, will adversely affect the hammer's hydraulic system, hindering its proper operation. Generally, to ensure that the accumulator's internal pressure matches the hydraulic system's pressure, nitrogen must be promptly charged or discharged. Therefore, a suitable charging and discharging device is an integral component of the accumulator.

[0003] An existing accumulator is connected to a valve, which has a connecting seat and a valve core for opening and closing a valve core air passage in the connecting seat. The valve core is threadedly connected to the connecting seat. The valve core air passage is provided with a first valve core air hole on the side of the valve core, and a second valve core air hole connected to the accumulator inner cavity is provided on the end face of the valve core. When in use, the valve core is unscrewed to expose the first valve core air hole in the cavity between the connecting seat and the valve core. The accumulator inner cavity can be connected to the outside of the accumulator through the valve core air passage, so that the accumulator can be charged and discharged. The valve core is screwed in so that the first valve core air hole is blocked by the connecting seat. The accumulator inner cavity and the accumulator outer cavity are cut off by the sealing body between the connecting seat and the valve core, which can prevent the gas in the accumulator inner cavity from leaking to the outside of the accumulator, or the gas outside the accumulator from entering the accumulator inner cavity.

[0004] Existing compressed natural gas (CNG) charging valves are equipped with a gas pipe connector for filling the container with CNG. Patent document CN209458450U describes a CNG charging valve structure for automobiles with a charging head, which is only suitable for filling gas tanks. However, the accumulator valve is equipped with a valve core that opens and closes the valve core air passage in the connection seat. Without the valve core, charging is impossible. The inventors searched the prior art but could not find a gas pipe connector suitable for charging or deflating the accumulator. Summary of the Invention

[0017] Preferably, when the threaded portion is fixedly connected to the connecting seat, the pipe connecting sleeve and the connecting seat form a pipe wall for connecting the first air channel and the valve core air channel.

[0022] A hydraulic pile hammer comprises a hammer body shell, a heavy hammer, a hydraulic oil supply device and the aforementioned energy storage device, wherein the energy storage device is arranged on the hammer body shell.

[0023] The beneficial effects of the present invention are:

[0024] 1. By operating the valve core operating tool, the position of the first valve core air hole of the valve core can be adjusted relative to the connecting seat, so that the valve is in the open or closed state. When the valve is in the closed state (that is, the valve core cuts off the valve core airway), the valve core operating tool cuts off the third airway; when the valve is in the open state (that is, the valve core opens the valve core airway), the third airway is connected to the first airway pipeline, and the first airway is connected to the valve core airway. The way the first airway is connected to the valve core airway is that the connecting seat and the pipe connecting sleeve form a pipeline wall connecting the first airway and the valve core airway. Using the trachea connector of the present invention, the fluid charging and discharging pipeline and the valve core airway can be conveniently connected, and the connection between the fluid charging and discharging pipeline and the valve core airway can be opened or cut off when needed. Here, since the valve core operating tool can cut off the first airway, it can prevent external moisture and dust from entering the fluid charging and discharging pipeline connected to the trachea connector, thereby improving the cleanliness of the fluid during the fluid charging and discharging process.

[0025] 2. When the tool head, the compression spring, the control head, the first anti-slip limiter, and the second anti-slip limiter are configured to form a valve core operating tool with adjustable length, the volume of the trachea joint can be reduced.

[0026] 3. By adjusting the position of the control head in the pipe connecting sleeve, that is, the pipe connecting sleeve seals the first opening to achieve the cutoff of the first airway and the third airway, that is, when the third airway is aligned with the first opening, the first airway and the third airway are connected.

[0027] 4. When the pipe sleeve and the connection base are threaded together, the sleeve must be rotated to connect them. The flexible connection between the sleeve and the connection base, and the flexible connection between the valve core operating tool and the sleeve, allows the sleeve to be screwed onto and removed from the connection base without twisting the connecting pipe connected to the first airway. The threaded connection between the valve core operating tool and the sleeve is simple and easy to use. This is especially effective when the threaded connection utilizes sealing threads.

[0028] 5. The relief valve is a device that regulates the flow of the medium by controlling the opening of the opening and closing parts within the valve body. The stop valve and the relief valve can be used together to realize simultaneous charging and discharging operations. That is, when the pressure in the accumulator is greater than the opening pressure of the relief valve, the accumulator is discharged. When the pressure in the accumulator is less than the opening pressure of the relief valve and the other end of the stop valve is connected to the air source, the accumulator can be charged.

[0029] 6. When the accumulator includes a charging module, the air pressure in the accumulator can be conveniently adjusted by controlling the use status of the charging module.

[0030] 7. When the hydraulic pile hammer is equipped with an energy storage device, the stability of the hydraulic pile hammer can be improved by adjusting the pressure balance between the accumulator pressure and the hydraulic oil supply device through the energy storage device.

DETAILED DESCRIPTION

[0041] The present invention is described below in the form of embodiments in conjunction with the accompanying drawings to assist those skilled in the art in understanding and implementing the present invention. Unless otherwise specified, the following embodiments and the technical terms therein should not be understood without reference to the technical background of the present art.

[0042] Figure 7A partial schematic diagram of an energy storage device is shown. An accumulator 51 is connected to a valve having a connection seat 502 and a valve core 53 for opening and closing a valve core air passage within the connection seat 502. The valve core 53 is threadedly connected to the connection seat 502. The valve core air passage has a first valve core air hole on the side of the valve core 53 and a second valve core air hole on the end face of the valve core 53 that communicates with the inner cavity of the accumulator 51. During use, when the valve core 53 is unscrewed so that the first valve core air hole is exposed in the cavity between the connecting seat 502 and the valve core 503, the inner cavity of the accumulator 51 can be connected to the outside of the accumulator 51 through the valve core air passage, so that the accumulator 51 can be charged and discharged; when the valve core 503 is screwed in so that the first valve core air hole is blocked by the connecting seat 502, the inner cavity of the accumulator 51 and the outside of the accumulator 51 are cut off by the sealing body between the connecting seat 502 and the valve core 503, which can prevent the gas in the inner cavity of the accumulator 51 from leaking to the outside of the accumulator 51, or the gas outside the accumulator 51 from entering the inner cavity of the accumulator 51. Generally, the valve core 53 is provided with a structure that facilitates screwing in and out, such as a slot, a cross slot, an inner hexagonal hole, or an outer hexagonal head.

[0043] Example 1: A trachea connector is used to connect a valve, the valve having a connecting seat and a valve core for opening and closing a valve core air channel in the connecting seat, wherein the side of the valve core adjacent to the outside of the cavity is provided as an exposed end, the valve core air channel is provided with a first valve core opening on the side of the valve core, and the valve core air channel is provided with a second valve core opening on the end face of the valve core adjacent to the side of the cavity.

[0044] See also Figure 1 The trachea joint includes a pipe seat sleeve 12, a pipe connection sleeve 10 and a valve core operating tool 13. In order to facilitate the operation of the valve core operating tool 13, the trachea joint of the present invention can also include a hand wheel 11.

[0045] See also Figure 1 The pipe connecting sleeve 10 is provided with a third air channel 102, the third air channel 102 is provided with a third opening on the outer wall of the pipe connecting sleeve 10, and the third air channel 102 is provided with a fourth opening on the inner wall of the pipe connecting sleeve 10. In order to facilitate the fixed connection of the air pipe joint and the valve, the connecting end of the pipe connecting sleeve 10 is also provided with a fixing portion 101. Figure 7 In the illustrated energy storage device, the connection base 502 is internally threaded, so a matching external thread is selected for the fixing portion 101. When the fixing portion 101 is fixedly connected to the connection base, the pipe connecting sleeve 10 and the connection base form a pipe wall for connecting the first air channel 131 and the valve core air channel.

[0046] See also Figure 1The connecting pipe seat sleeve 12 is movably mounted on the pipe connecting sleeve 10, and a second air duct 121 is provided on the connecting pipe seat sleeve 12. The second air duct 121 is used to connect other pipeline components, which may be pipe connectors or plugs. In this embodiment, the second air duct 121 is provided with a fifth opening on the outer wall of the connecting pipe seat sleeve 12, and a sixth opening on the inner wall of the connecting pipe seat sleeve 12. An internal thread for connecting the pipe connector is provided on the inner wall of the fifth opening of the connecting pipe seat sleeve 12. The connecting pipe seat sleeve 12 is connected to the pipe connecting sleeve 10 by a rotating pair, and a first dynamic seal for connecting the second air duct 121 and the third air duct 102 through a pipeline is provided between the connecting pipe seat sleeve 12 and the pipe connecting sleeve 10. In this embodiment, the first sealing ring 171 and the second sealing ring 172 form the first dynamic seal between the connecting pipe seat sleeve 12 and the pipe connecting sleeve 10. The first sealing ring 171 and the second sealing ring 172 are respectively arranged on both sides of the sixth opening and the third opening, so as to avoid the presence of an air leak on the connection surface between the pipe seat sleeve 12 and the pipe connecting sleeve 10.

[0047] See also Figure 1 The valve core operating tool 13 has an integrally formed control head and a tool head. The valve core operating tool 13 is movably arranged in the pipe connecting sleeve 10. The valve core operating tool 13 is provided with a tool portion 134 for cooperating with the valve core and a first air channel 131 for connecting the valve core air channel. If the exposed end of the valve core is provided with a straight groove structure, the tool portion 134 can be a straight head. If the exposed end of the valve core is provided with a cross groove structure, the tool portion 134 can be a cross head. If the exposed end of the valve core is provided with an inner hexagonal hole structure, the tool portion 134 can be an outer hexagonal head. If the exposed end of the valve core is provided with an outer hexagonal head structure, the tool portion 134 can be an inner hexagonal hole. The first air channel 131 is provided with a first opening on the side of the valve core operating tool 13 and a second opening 133 on the tool head side of the valve core operating tool. In the valve to be operated in this embodiment, the valve core is threadedly connected to the connecting seat. Therefore, the valve core operating tool 13 and the pipe connecting sleeve 10 can be connected by a cylindrical pair or a threaded pair. When the valve core operating tool 13 and the pipe connecting sleeve 10 are connected by a cylindrical pair, it is necessary to control the relative position of the first opening and the fourth opening during use, or use a pin or a set bolt to lock the relative position of the valve core operating tool 13 and the pipe connecting sleeve 10. Figure 1 The illustrated tracheal connector locks the relative position of the valve core operating tool 13 and the pipe connection sleeve 10 by cooperating with the movable pin 16 and the first anti-dropout pin hole 135 or the second anti-dropout pin hole 136. Specifically, the movable pin 16 is radially inserted through the pipe connection sleeve 10, and the first anti-dropout pin hole 135 and the second anti-dropout pin hole 136 are provided axially along the valve core operating tool 13. When the movable pin 16 is inserted into the first anti-dropout pin hole 135, the first opening is offset from the fourth opening. When the movable pin 16 is inserted into the second anti-dropout pin hole 136, the first opening is aligned with the fourth opening.

[0048] When in use, the opening and closing effects of the first air channel 131 and the third air channel 102 are achieved by adjusting the relative positions of the valve core operating tool 13 and the pipe connecting sleeve 10, that is, controlling the relative positions of the first opening and the fourth opening.

[0049] When it is necessary to cut off the connection between the first air channel 131 and the third air channel 102, the wall of the valve core operating tool 13 is connected to the fourth opening, and the wall of the pipe connecting sleeve 10 is connected to the first opening, so that the connection between the first air channel 131 and the third air channel 102 can be cut off.

[0050] When communication between the first air channel 131 and the third air channel 102 is required, the first opening is aligned with the fourth opening to achieve communication between the first air channel 131 and the third air channel 102. To achieve fluid charging and discharging of the valve, the first air channel must also be connected to the valve core air channel when the first opening is aligned with the fourth opening. To achieve this connection, the first valve core opening must be exposed outside the connection seat and the valve core.

[0051] To reduce fluid leakage at the connection surface between the valve core operating tool 13 and the tube connection sleeve 10 when the first air channel 131 and the third air channel 102 are connected, a second dynamic seal is provided between the valve core operating tool 13 and the tube connection sleeve 10. Since fluid leakage between the valve core operating tool 13 and the tube connection sleeve 10 at the connection end of the tube connection sleeve 10 does not affect the inflation and deflation effects, the second dynamic seal only needs to be provided between the first opening and the operating end of the valve core operating tool 13. In this way, after the first opening and the fourth opening are aligned, the second dynamic seal can reduce fluid leakage. In this embodiment, the third sealing ring 173 and the fourth sealing ring 174 can both form the second dynamic seal between the valve core operating tool 13 and the tube connection sleeve 10.

[0052] If the tracheal joint of the present invention further comprises a hand wheel 11, the hand wheel and the tail end of the pipe connecting sleeve 10 are circumferentially frictionally connected to realize the function of rotating the pipe connecting sleeve 10. The hand wheel and the tail end of the pipe connecting sleeve 10 are axially frictionally connected to realize the function of pushing and pulling the pipe connecting sleeve 10.

[0053] Example 2: A trachea connector is used to connect a valve, the valve having a connecting seat and a valve core for opening and closing the valve core air channel in the connecting seat, the valve core is threadedly connected to the connecting seat, and the side of the valve core adjacent to the outside of the cavity is set as an exposed end, the valve core air channel is provided with a first valve core opening on the side of the valve core, and the valve core air channel is provided with a second valve core opening on the end face of the valve core adjacent to the side of the cavity.

[0054] See also Figure 2The tracheal connector includes a pipe seat sleeve 12, a pipe connection sleeve 10, and a valve core operating tool. In this embodiment, the pipe seat sleeve 12 and the pipe connection sleeve 10 can still adopt the corresponding structures of Example 1. The difference between this embodiment and Example 1 is that the valve core operating tool adopts a split structure, and a first anti-disengagement limiter and a second anti-disengagement limiter are fixedly connected to the pipe connection sleeve 10, as described below.

[0055] The valve core operating tool includes a tool head 13, a compression spring 15 and a control head 14. The tool part 134 is arranged on the tool head 13. The tool head 13 is connected to the control head 14 in a movable manner. The two ends of the compression spring 15 respectively press the tool head 13 on the first anti-slip limit part and press the control head 14 on the second anti-slip limit part.

[0056] Since the valve core needs to be unscrewed when the valve core airway is opened, the compression spring 15 presses the tool head 13 against the first anti-slip limiter. This prevents the tool head 13 from slipping out while also effectively cooperating with the corresponding structure on the valve core. During the process of unscrewing the valve core, the elastic length of the compression spring 15 can adjust the distance between the control head 14 and the tool head 13, thereby providing the valve core with a sufficient withdrawal distance. The tool head 13 and the control head 14 are connected by a sliding pair, which not only adjusts the distance between the tool head 13 and the control head 14, but also transmits the circumferential force of the rotating control head 14 to the tool head 13.

[0057] The first air channel includes a 1A segmented fluid conduit 131 provided on the tool head 13 and a 1B segmented fluid conduit 141 provided on the control head 14. The 1A segmented fluid conduit 131 is connected to the 1B segmented fluid conduit 141. The 1B segmented fluid conduit 141 has a first opening on the side of the control head 14. When the valve core operating tool is in the closed position of the pipe connecting sleeve 10, the pipe connecting sleeve 10 seals the first opening. When the valve core operating tool is in the open position of the pipe connecting sleeve 10, the first opening is connected to the third air channel 102. Figure 2 The tool head 13 has a prismatic slot at its rear end. The 1A segmented fluid conduit 131 has a seventh opening at the bottom of the slot. A prismatic plug that matches the prismatic hole is located at the front end of the control head 14. The plug is inserted into the slot to form a moving pair. The prismatic plug of the 1B segmented fluid conduit 14 has an eighth opening on its end face, ensuring communication between the 1A segmented fluid conduit 131 and the 1B segmented fluid conduit 141.

[0058] In order to facilitate the fixed connection between the trachea joint and the valve, the connecting end of the pipe connecting sleeve 10 is also provided with a fixing portion 101. Figure 7In the illustrated energy storage device, the connection base 502 is internally threaded, so a matching external thread is selected for the fixing portion 101. When the fixing portion 101 is fixedly connected to the connection base, the pipe connecting sleeve 10 and the connection base form a pipe wall for connecting the first air channel 131 and the valve core air channel.

[0059] Typically, when the control head 14 is connected to the cylindrical pair of the pipe connecting sleeve 10, the valve core operating tool can be used to open and close the third air passage 102 by pushing the control head 14 to align the first opening with the fourth opening. However, this method is not easy to operate, and it is best to use a pin and a set bolt to lock the relative position of the control head 14 and the pipe connecting sleeve 10, as in Example 1.

[0060] Alternatively, the control head 14 and the pipe connection sleeve 10 can be threadedly connected. The first opening is defined on the side of the control head 14 within the fluid conduit 141 of segment 1B.
