Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a hydraulic locking pin. Background Art

[0002] The hydraulic locking pin used in wind power generation equipment is composed of a locking pin head, a piston rod assembly, an end cover, a flange, a locking plate, a sensor, some standard parts, seals and other components. Under the action of hydraulic pressure, the locking pin head is pushed into the cone pin hole of the wind wheel to lock the wind wheel.

[0003] Among them, in the existing technology, the cost of locking pin heads and guide sleeve materials on the market accounts for a large proportion of the entire project. If the production cost of locking pin heads and guide sleeve materials is too high due to complex design problems, it will increase the company's use burden. Hereby, a hydraulic locking pin is proposed to achieve the purpose of cost reduction through structural redesign. Utility Model Content

If the production cost of the locking pin head and the guide sleeve materials is too high due to complex design, it will increase the use burden of the enterprise.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hydraulic locking pin comprises a locking pin head, an outer ring sleeve of the locking pin head is provided with a guide sleeve, one side of the guide sleeve is provided with a plurality of screw holes, one side of the locking pin head is provided with a flange plate, one side of the flange plate is provided with a plurality of connecting screws, one end of the connecting screws passes through the adjacent flange plate cavity and is connected to the corresponding screw hole, one end of the locking pin head is fixedly connected to a bracket, and the inner cavity of the flange plate is provided with a sensor.

[0007] Preferably, one end of the sensor passes through the inner cavity of the flange and fits with one end of the bracket.

[0008] Preferably, the outer ring of the locking pin head is snap-fitted with the inner cavity of the guide sleeve.

[0009] Preferably, there is a one-to-one correspondence between the plurality of connecting screws and the plurality of screw holes, and the outer ring of the connecting screw is screwed and connected to the inner cavity of the corresponding screw hole through a thread.

[0010] Preferably, a gasket is sleeved on the outer ring of the sensor, and one side of the gasket is fixedly connected to one end of an adjacent flange by screws.

[0011] Preferably, a plurality of the connecting screws are distributed in a circular array at one end of the guide sleeve.

[0012] The utility model has at least the following beneficial effects:

[0013] When the hydraulic locking pins on the market are in use, the sensor is in direct contact with the locking pin head, and there is no auxiliary support structure to help the sensor stabilize. There are certain risks during use. The design of this structure avoids direct contact between the sensor and the locking pin head. Instead, a space is left between the sensor and the locking pin head through the bracket, which indirectly ensures the stable operation of the sensor. The optimized locking pin is more durable and greatly reduces the material cost required for production. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, when the hydraulic locking pin on the market is in use, the sensor 6 is in direct contact with the locking pin head 1, and there is no auxiliary supporting structure to help the sensor 6 to stabilize, and there are certain risks during use. The design of this structure avoids direct contact between the sensor 6 and the locking pin head 1, but leaves space between the sensor 6 and the locking pin head 1 through the bracket 3, which indirectly ensures the stable operation of the sensor 6. The optimized locking pin is more durable and greatly reduces the material cost required for production.

[0019] This program has the following working process:

[0020] When the hydraulic locking pin on the market is in use, the sensor 6 is in direct contact with the locking pin head 1, and there is no auxiliary support structure to help the sensor 6 to stabilize. There are certain risks during use. The design of this structure avoids direct contact between the sensor 6 and the locking pin head 1.

[0021] According to the above working process, we can know that:

[0022] The bracket 3 leaves space between the sensor 6 and the locking pin head 1, which indirectly ensures the stable operation of the sensor 6. The optimized locking pin is more durable, which greatly reduces the material cost required for production.

[0023] Furthermore, one end of the sensor 6 passes through the inner cavity of the flange 5 and fits with one end of the bracket 3 .

[0024] Furthermore, the outer ring of the locking pin head 1 is engaged with the inner cavity of the guide sleeve 2 .

[0025] Furthermore, there is a one-to-one correspondence between the plurality of connecting screws 4 and the plurality of screw holes, and the outer ring of the connecting screw 4 is screwed and connected with the inner cavity of the corresponding screw hole through a thread.

[0026] Furthermore, a gasket is sleeved on the outer ring of the sensor 6, and one side of the gasket is fixedly connected to one end of the adjacent flange 5 by screws.

[0027] Furthermore, a plurality of connecting screws 4 are distributed in a circular array at one end of the guide sleeve 2 .

[0028] To sum up: when the hydraulic locking pin on the market is in use, the sensor 6 is in direct contact with the locking pin head 1, and there is no auxiliary supporting structure to help the sensor 6 to stabilize. There are certain risks during use. The design of this structure avoids direct contact between the sensor 6 and the locking pin head 1, and instead leaves space between the sensor 6 and the locking pin head 1 through the bracket 3, which indirectly ensures the stable operation of the sensor 6. The optimized locking pin is more durable and greatly reduces the material cost required for production.
