Description

Technical Field

[0001] The utility model relates to the field of wind power vibration reduction hydraulic elastic support, and more specifically, to a novel elastic support device. Background Art

[0002] In order to ensure the smooth output of the torque of the gearbox components in the transmission system of the wind turbine generator set and to minimize the vibration and noise generated by the operation of the system, the role of the gearbox elastic support that fixes the torque arms at both ends of the gearbox is particularly important. Therefore, it is necessary to use hydraulic elastic supports to elastically support the torque arms at both ends of the generator to withstand the torsional load of the gearbox. Each wind turbine uses 2 sets of elastic supports, a total of 4 hydraulic elastic support nodes, which are cross-connected by high-pressure hoses to form 2 sets of hydraulic auxiliary systems. By injecting antifreeze at a specific pressure, the elastic support has high torsional stiffness and low vertical stiffness. The hydraulic system provides the main stiffness, and the elastic support can absorb the vibration of the gearbox and reduce noise.

[0003] When the hydraulic elastic pad is loaded, the rubber volume will expand and the volume of the inner cavity will increase. The volume of the liquid initially filled is certain, which will cause the pressure of the liquid to drop, thus affecting the use effect of the elastic support. In order to solve this problem, an automatic liquid injection device is generally set on it (sensors, liquid injection motors, solenoid valves, etc. are required). However, liquid injection does not occur frequently. Such a setting undoubtedly increases the cost, and it is also necessary to properly solve the power supply problem of the above-mentioned electrical appliances. However, manual addition cannot accurately control the amount of liquid added.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a new elastic support device. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model inserts the infusion tube into the injection tube on the hydraulic elastic pad where liquid needs to be injected. At this time, the rubber pad is squeezed, thereby improving the sealing of the connection between the two. Then, valve A and valve B are opened, and liquid can be input into the infusion tube by manually squeezing the liquid outlet assembly. Then, the liquid is injected into the hydraulic elastic pad through the injection tube. Since it is manual, no electrical appliances are needed, which not only saves costs, but also does not need to consider power supply issues. At the same time, the amount of liquid added can be more accurately controlled by manually squeezing the components on the liquid outlet assembly, thereby solving the problem in the background technology that the setting of adding an automatic liquid injection device undoubtedly increases the cost, and also needs to properly solve the power supply problem of the above-mentioned electrical appliances, but manual addition cannot accurately control the amount of liquid added;

[0016] 2.

During the movement of the extrusion plate, the through groove on the extrusion plate will slide along the square limit plate to maintain the linear movement of the square limit plate, and the square limit plate can extrude the extrusion type liquid capsule. Due to the rotation control, it is more conducive to controlling the amount of liquid added than direct manual extrusion;

[0017] 3. The new type can understand the amount of liquid added according to the indicator scale on the square limit plate corresponding to the L-shaped plate, which is more conducive to the staff to accurately control the amount of liquid added. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1-4As shown, the utility model provides a novel elastic support device, including a lower base plate 1, and columns 2 located on both sides of the top of the lower base plate 1, the heads of the columns 2 are equipped with cross beams 3, and the three are combined into a U-shaped structure, the top of the lower base plate 1 and the bottom of the cross beam 3 are both equipped with hydraulic elastic pads 4, and the hydraulic elastic pads 4 are both equipped with injection tubes 5 equipped with valves A6, and the surface of the column 2 is equipped with a manual liquid squeezing component 12, through which the liquid inside is squeezed out and infused into the injection tube 5 through the infusion tube 7, and the head of the infusion tube 7 is equipped with a plug-in tube 8 that can be inserted into the injection tube 5, and a rubber pad 9 is bonded to the contact portion between the plug-in tube 8 and the injection tube 5, and a valve B10 is provided on the plug-in tube 8, and the column 2 can be designed to be hollow to reduce the weight of the elastic support and make it more convenient to transport and install it.

[0026] Insert the infusion tube 7 into the injection tube 5 on the hydraulic elastic pad 4 where liquid needs to be injected. At this time, the rubber pad 9 is squeezed, thereby improving the sealing of the connection between the two. Then open the valve A6 and the valve B10, and input liquid into the infusion tube 7 through the manual squeezing liquid outlet component 12. Then the liquid is injected into the hydraulic elastic pad 4 through the injection tube 5. Since it is manual, no electrical appliances are needed, which not only saves costs, but also does not need to consider power supply issues. At the same time, the amount of liquid added can be more accurately controlled by the components on the manual squeezing liquid outlet component (the structure of the manual squeezing liquid outlet component 12 will be introduced later). After the injection is completed, close the above two valves and pull the infusion tube 7 out of the injection tube 5.

[0027] Furthermore, the manual liquid squeezing component 12 includes an extrusion type liquid capsule 121 installed on the surface of the beam 3, an extrusion plate 122 is installed on the surface of the extrusion type liquid capsule 121 opposite to the beam 3, an L-shaped plate 123 is installed on the surface of the beam 3 located above the extrusion type liquid capsule 121, the internal thread of the L-shaped plate 123 is connected to a screw 124, the head of the screw 124 is rotatably connected to the surface of the extrusion plate 122 through a bearing, a through groove 125 is also provided on the surface of the extrusion plate 122, a square limit plate 126 with the same cross-section as the through groove 125 is fixedly connected to the surface of the extrusion plate 122, the extrusion type liquid capsule 121 and the infusion tube 7 are connected to each other, and the head of the screw 124 is fixedly connected to a handle 127 for facilitating its rotation.

[0028] That is, a sufficient amount of liquid is added to the squeeze type liquid capsule 121 in advance (the squeeze type liquid capsule 121 is made of elastic material and is in an expanded state under normal circumstances, and can be filled with a sufficient amount of liquid). The screw 124 is rotated clockwise through the handle 127, and the screw 124 moves along the L-shaped plate 123 toward the squeeze type liquid capsule 121. The screw 124 rotates along the squeeze plate 122, and at the same time drives the squeeze plate 122 to move toward the squeeze type liquid capsule 121. During the movement of the squeeze plate 122, the through groove 125 thereon will slide along the square limiting plate 126 to maintain the linear movement of the square limiting plate 126. The square limiting plate 126 can squeeze the squeeze type liquid capsule 121. Since it is controlled by rotation, it is more conducive to controlling the amount of liquid added than directly squeezing it by hand.

[0029] In addition, the surface of the square limit plate 126 is marked with a liquid output scale, which is a scale obtained by actually squeezing the above-mentioned squeeze-type liquid bag 121. The amount of liquid added can be understood according to the indicating scale on the square limit plate 126 corresponding to the L-shaped plate 123, which is more conducive to the staff to accurately control the amount of liquid added. A pipe reel 11 is installed on the side end of the beam 3 to wind the infusion tube 7 for the convenience of collecting the infusion tube 7 (it should be noted that the infusion tube 7 is relatively thin, and the liquid remaining in the infusion tube 7 can be ignored). The side end of the L-shaped plate is threadedly connected with a fixing screw 13. By tightening the fixing screw 13, its head is pressed against the outer wall of the screw 124 to limit the rotation of the screw 124 and prevent the screw 124 from rotating due to external force.
