[0036] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, they can be understood as further technical solutions without creative effort. In some drawings, components with the same structure or function are only schematically illustrated, or only one is marked. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0037] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] Reference Figs. 1-3 The first embodiment of this utility model proposes a buffer device for an electric cylinder tensioning device, comprising: a base 1; a hydraulic cylinder 2 oscillatingly mounted on the base 1, the hydraulic cylinder 2 being used to eliminate and buffer changes in tension caused by sudden changes during the operation of the conveyor after extension and retraction; a connecting member 3 having a first connecting end 31 and a second connecting end 32, the first connecting end 31 being connected to the hydraulic cylinder 2; and an accumulator 4 having its second connecting end 32 being connected to the accumulator 4, the accumulator 4 being used to regulate and stabilize the oil pressure inside the hydraulic cylinder 2.

[0040] In this embodiment, the base 1 is installed in a suitable position, and the hydraulic cylinder 2 is mounted on the base 1 via a suitable swing structure (such as a hinge), allowing the hydraulic cylinder 2 to swing within a certain range. When the conveyor tension suddenly increases, the hydraulic cylinder 2 extends to buffer and eliminate the increased tension; when the conveyor tension suddenly decreases, the hydraulic cylinder 2 retracts to buffer and eliminate the decreased tension. The first connecting end 31 of the connector 3 is connected to the hydraulic cylinder 2, and the second connecting end 32 is connected to the accumulator 4. The accumulator 4 can be pre-charged with gas at a certain pressure or use other suitable energy storage methods. During the operation of the hydraulic cylinder 2, when the oil pressure changes, the accumulator 4 will draw in or discharge oil according to the oil pressure, thereby stabilizing the oil pressure inside the hydraulic cylinder 2.

[0041] The tensioning and detensioning of the conveyor is achieved by extending and retracting the hydraulic cylinder 2. This allows for adjustment of the conveyor's tension according to its actual operating conditions, ensuring normal operation. The accumulator 4 effectively regulates the oil pressure within the hydraulic cylinder 2, reducing the impact of oil pressure fluctuations on the cylinder 2 and the entire tensioning device, thus improving equipment stability and reliability and extending its service life.

[0042] Furthermore, one end of the oil pipe 5 is connected to the accumulator 4, and the other end is connected to the second connection end 32. The second connection end 32 is connected to the accumulator 4 through the oil pipe 5.

[0043] In this embodiment, one end of the oil pipe 5 is connected to the accumulator 4, and the other end is connected to the second connecting end 32 of the connector 3. This ensures that the connection of the oil pipe 5 is secure and well-sealed to prevent oil leakage. The accumulator 4 and the cylinder 2 are thus connected via the oil pipe 5 and the connector 3. When the oil pressure inside the cylinder 2 changes, the oil can flow between the accumulator 4 and the cylinder 2 through the oil pipe 5 to regulate the oil pressure.

[0044] The oil pipe 5 provides a channel for oil flow, making oil exchange between the accumulator 4 and the cylinder 2 smoother. Compared with a direct connection, the oil pipe 5 can be arranged more flexibly to adapt to different installation spaces and equipment layout requirements, improving the installation convenience and versatility of the buffer device.

[0045] Furthermore, connector 3 also has a third connection end 33, on which sensor 6 is disposed.

[0046] In this embodiment, a sensor 6 is installed on the third connection end 33 of the connector 3. The sensor 6 is a pressure sensor 6, used to monitor the pressure parameters of the oil inside the connector 3 in real time. During installation, it is necessary to ensure that the sensor 6 is tightly connected to the third connection end 33, and that the signal output line of the sensor 6 is connected to the corresponding monitoring equipment or control system.

[0047] Sensor 6 is configured to acquire real-time pressure data of the oil within connector 3. By monitoring these parameters, operators can promptly understand the operating status and oil pressure changes of cylinder 2, enabling adjustments and maintenance of the equipment. Simultaneously, the monitoring data from sensor 6 can be fed back to the control system, achieving automated control and adjustment of the buffer device and enhancing the equipment's intelligence. Pressure sensor 6 outputs a pressure signal, which is then converted into a tension value based on the cylinder diameter and rod dimensions of the buffer cylinder 2.

[0048] Furthermore, the connector 3 also has a fourth connection end 34. One end of the check valve 7 is connected to the fourth connection end 34, and the other end is used to connect to the oil replenishing component. The oil replenishing component delivers oil to the oil cylinder 2 through the check valve 7 and the connector 3.

[0049] In this embodiment, the fourth connection end 34 of the connector 3 is connected to one end of the check valve 7. The check valve 7 is connected to the oil pump (oil replenishment component) to replenish the hydraulic oil in the buffer device.

[0050] The one-way valve 7 and the oil replenishment component ensure that there is sufficient oil in the oil cylinder 2.

[0051] Furthermore, there are several connector seats 8, correspondingly disposed on the first connecting end 31, the second connecting end 32, and the third connecting end 33; the sliding sleeve 9 is slidably disposed on the connector seat 8; there are several quick connectors 10, correspondingly disposed on the oil pipe 5, the sensor 6, and the one-way valve 7. After the sliding sleeve 9 slides, the quick connector 10 is used to engage or disengage from the connector seat 8. In this embodiment, the connector seat 8, the sliding sleeve 9, and the quick connector 10 are common quick connectors 10 in the prior art.

[0052] In this embodiment, connector seats 8 are respectively installed on the first connecting end 31, the second connecting end 32, and the third connecting end 33 of the connector 3. Quick connectors 10 are correspondingly installed on the oil pipe 5, the sensor 6, and the one-way valve 7. The sliding sleeve 9 is slidably disposed on the connector seat 8. When connection is required, the sliding sleeve 9 is pushed to make the quick connector 10 snap into the connector seat 8, realizing the quick connection between the oil pipe 5, the sensor 6, the one-way valve 7 and the connector 3; when disassembly is required, the sliding sleeve 9 is slid to make the quick connector 10 disengage from the connector seat 8.

[0053] The fittings 8, 9, and 10 enable quick connection and disconnection of the oil pipe 5, sensor 6, and check valve 7 with the connector 3. This significantly saves time and labor costs and improves work efficiency during equipment installation, commissioning, and maintenance. Furthermore, this connection method provides excellent sealing performance, effectively preventing oil leakage and ensuring the normal operation of the buffer device.

[0054] Furthermore, the rotating component 11 is rotatably mounted on the connecting component 3; there are several connecting rods 12, one end of which is rotatably mounted on the sliding sleeve 9, and the other end of which is rotatably mounted on the rotating component 11. After the rotating component 11 rotates, it drives several sliding sleeves 9 to slide synchronously through the connecting rod 12.

[0055] In this embodiment, the rotating component 11 is rotatably mounted on the connecting component 3, and one end of the connecting rod 12 is rotatably mounted on the sliding sleeve 9, while the other end is rotatably mounted on the rotating component 11. When multiple sliding sleeves 9 need to be operated synchronously, the rotating component 11 is rotated, and the rotating component 11 drives several sliding sleeves 9 to slide synchronously through the connecting rod 12, thereby realizing the synchronous connection or disconnection of the oil pipe 5, sensor 6, and one-way valve 7 with the connecting component 3.

[0056] The arrangement of the rotating component 11 and the connecting rod 12 enables the synchronous sliding of multiple sliding sleeves 9. This avoids the tedious process of operating each sliding sleeve 9 individually, further improving the efficiency of equipment connection and disassembly. Simultaneously, it ensures the synchronicity and consistency of each connection part, reducing connection problems that may occur due to asynchronous operation and improving the reliability of the buffer device.

[0057] Furthermore, the limiting shaft 13 is mounted on the sliding sleeve 9, and one end of the connecting rod 12 rotates along the limiting shaft 13.

[0058] In this embodiment, a limiting shaft 13 is provided on the sliding sleeve 9, and one end of the connecting rod 12 is sleeved on the limiting shaft 13 and can rotate along the limiting shaft 13. The limiting shaft 13 plays a role in limiting and guiding the rotation of the connecting rod 12.

[0059] Furthermore, the limiting shaft 13 is raised and lowered on the sliding sleeve 9. The limiting shaft 13 has a coarse diameter section 131 and a fine diameter section 132 arranged sequentially from low to high in the vertical direction. The connecting rod 12 has a rotating hole 121 and a sliding groove 122. The rotating hole 121 communicates with the sliding groove 122. The diameter of the rotating hole 121 is equal to the diameter of the coarse diameter section 131, and the width of the sliding groove 122 is equal to the diameter of the fine diameter section 132. After the sliding sleeve 9 descends, the fine diameter section 132 slides along the sliding groove 122.

[0060] In this embodiment, the limiting shaft 13 is vertically and elliptically mounted on the sliding sleeve 9. It has a coarse diameter section 131 and a fine diameter section 132, arranged vertically from low to high. The connecting rod 12 is provided with a rotating hole 121 and a sliding groove 122, with the rotating hole 121 communicating with the sliding groove 122. When the sliding sleeve 9 is in the initial position, the coarse diameter section 131 of the limiting shaft 13 is located within the rotating hole 121, and the connecting rod 12 can rotate around the coarse diameter section 131. When the sliding sleeve 9 descends, the narrow diameter section 132 is located in the rotating hole 121. The narrow diameter section 132 can enter the sliding groove 122 and slide along the sliding groove 122, realizing the relative movement between the connecting rod 12 and the limiting shaft 13. After the limiting shaft 13 slides, the sliding sleeve 9 also slides along the sliding groove 122. The arrangement direction of the sliding groove 122 is the same as the sliding direction of the sliding sleeve 9, so the installation of a single quick connector 10 can be realized. During installation, the limiting shaft 13 is pressed down, and the sliding sleeve 9 is slid after pressing down. When installing one quick connector 10, it does not affect the status of other quick connectors 10.

[0061] Furthermore, one end of the elastic element 14 is disposed on the sliding sleeve 9, and the other end is disposed on the limiting shaft 13. The elastic element 14 is used to provide the force for the limiting shaft 13 to rise.

[0062] In this embodiment, one end of the elastic element 14 is mounted on the sliding sleeve 9, and the other end is mounted on the limiting shaft 13. The elastic element 14 can be a spring or other elastic component. In the initial state, the elastic element 14 applies an upward force to the limiting shaft 13, keeping the limiting shaft 13 in a higher position. When the sliding sleeve 9 descends, the elastic element 14 is compressed, providing a restoring force for the limiting shaft 13 to rise.

[0063] The elastic element 14 ensures that the limiting shaft 13 automatically rises back to its initial position after the sliding sleeve 9 descends. This reduces manual intervention during repeated operation of the equipment, improving its automation level and ease of operation. Simultaneously, the elastic element 14 also acts as a buffer and shock absorber, reducing impact and wear between the limiting shaft 13 and the sliding sleeve 9, thus extending the equipment's service life.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
