Description
Technical Field
The utility model relates to a wind power generation equipment field specifically is a frock is changed to wind generating set driftage brake block.
Background
With the continuous development of new energy industry, the maintenance level of the wind driven generator is also continuously improved. At present, a yaw brake system of a wind driven generator is positioned between a tower barrel and a main frame, when the wind direction changes and the yaw angle needs to be adjusted, the pressure of the yaw brake system is reduced, a yaw driving motor acts, at the moment, a yaw brake clamps a brake disc under the action of yaw residual pressure to generate proper damping, the back-and-forth swinging of an engine room under the action of wind is prevented when the engine room is in yaw, after the yaw angle position is reached, a driving device stops working, the yaw brake is provided with a hydraulic station to supply oil pressure again, and the engine room and the tower barrel are firmly locked by the brake to prevent the engine room from back-. The yaw brake consists of two clamps and is symmetrically arranged on two sides of the brake disc. Each clamp is composed of a main body, a friction plate and two end stop blocks, and the main body comprises two pistons. The friction plate is placed in a dedicated groove of the main body. During yaw, the yaw brake has a damping pressure of 15bar, the yaw brake friction plate and the brake disc rub against each other, after long-time operation, the thickness of the friction plate is reduced, and when the thickness of the friction plate is lower than the safe use thickness, the friction plate needs to be replaced. The stop blocks at two ends of the brake are removed when the brake pad is replaced, because the brake oil cylinder is not reset or the brake pad is blocked with the main body, the brake pad needs to be jacked by a crowbar, and the crowbar is knocked by a hammer to jack the brake pad a little by a little to replace the new brake pad. When the yaw brake pad is replaced, the working position is limited, the hammer is used for preventing the brake pad from being stressed, and the working efficiency is affected by time and labor consumption.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a convenient to use is provided, labour saving and time saving improves the wind generating set driftage brake block change frock of maintenance efficiency.
In order to solve the problem, a frock is changed to wind generating set driftage brake block, including the fixed bolster, its characterized in that: a groove is formed in the middle of the horizontal part of the fixed support, threaded holes distributed in a triangular shape are formed in the vertical part, and a lead screw group is arranged in the threaded hole at the uppermost end in a matched mode; the lead screw group is provided with nuts distributed front and back, the front end of the rear end nut corresponds to the lead screw group, and an L-shaped brake pad ejector rod is sleeved on the lead screw group and penetrates through the groove and is parallel and level to the upper end of the horizontal part of the fixed support.
The tail end of the ejector rod of the L-shaped brake pad is wedge-shaped.
And a through hole is formed in the vertical part of the top end of the ejector rod of the L-shaped brake pad.
The width dimension of the groove is slightly larger than that of the ejector rod of the L-shaped brake pad.
Compared with the prior art, the utility model has the following advantage:
the utility model discloses owing to be provided with lead screw group and L type brake block ejector pin, can remove L type brake block ejector pin along lead screw group direction through the nut during use, and then easily ejecting fast through the brake block that L type brake block ejector pin will need to be changed, convenient to use, labour saving and time saving improves maintenance efficiency.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the fixing bracket of the present invention;
fig. 3 is the schematic diagram of the structure of the L-shaped brake pad post rod of the present invention.
In the figure: 1. the brake pad comprises a fixed support, 2 grooves, 3 threaded holes, 4 screw rod groups, 5 nuts, 6L-shaped brake pad ejector rods and 7 through holes.
Detailed Description
As shown in fig. 1, 2 and 3, the tool for replacing the yaw brake pad of the wind generating set comprises a fixed support 1, wherein a groove 2 is formed in the middle of the horizontal part of the fixed support 1, threaded holes 3 distributed in a triangular shape are formed in the vertical part of the fixed support 1, and a screw rod group 4 is arranged in the uppermost threaded hole 3 in a matched manner; the screw group 4 is provided with nuts 5 distributed front and back, the front end of the rear nut 6 corresponds to the screw group 4 and is sleeved with an L-shaped brake pad ejector rod 6, and the L-shaped brake pad ejector rod 6 penetrates through the groove 2 and is flush with the upper end of the horizontal part of the fixed support 1.
During the use, install fixed bolster 1 at driftage brake block position through the screw, make the brake block that needs to be changed of alignment of 6 top portions of L type brake block ejector pin, swivel nut 5 makes it constantly be close to fixed bolster 1 along lead screw group 4, nut 5 removes the process and promotes L type brake block ejector pin 6 and moves along lead screw group 4 forward, the brake block that finally will change is ejecting, the operation in-process, do not have too high requirement to the operation space, can not receive the restriction in operation space, can relax fast swivel nut 5 with the help of sleeve or spanner, high durability and convenient use, time saving and labor saving, and the maintenance efficiency is effectively improved.
