Description

Technical Field

[0001] The utility model relates to the technical field of generator brakes, in particular to a brake bushing pressing mechanism and a mounting device thereof. Background Art

[0002] The brake of a hydro-turbine generator set is a device used to control the speed of a hydro-turbine generator and stop it. It forces the rotating parts to stop by mechanical means. During the shutdown process of the unit, when the speed drops to a certain specified value, compressed air is introduced to lift the brake block and press it against the brake ring of the generator rotor, forming friction, so that the unit is braked and stopped. The brake mainly controls the speed of the hydro-turbine generator through the brake mechanism. When the rotation of the hydro-turbine generator needs to be stopped, the brake controller is turned on, causing friction between the brake plate and the brake ring, thereby achieving deceleration and stopping of the machine.

[0003] During use, the generator's brake needs to be installed into the inner wall of the brake cylinder, and the bushing and bushing sealing ring fit tightly against the inner wall of the brake cylinder. It is very difficult to press it manually and it is easy to cause uneven force on the bushing and deviation from the vertical line. Manual pressing cannot ensure that the pressure applied is uniform and appropriate, which can easily damage the bushing or other components. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a brake bushing clamping mechanism, which can achieve the effect of uniform force on the bushing when it is installed in the brake cylinder, and includes a pressing component 100, including a bracket 101, a support assembly 102 fixedly connected to the bracket 101, the support assembly 102 sets the rotating assembly 103 at the center of a circle just above the brake, the movable assembly is the rotating assembly 103 in the support assembly 102, the rotating assembly 103 can adjust the height of the linkage assembly 104, the linkage assembly 104 set on the rotating assembly 103, and the extrusion assembly 105 set on the linkage assembly 104.

[0033] The mounting component 200 quickly fixes the extrusion mechanism above the brake, and includes a control component 201 movably connected to the bracket 101. The control component 201 can drive the limit component 202 to rotate when it is in operation. The limit component 202 is movably connected to the control component 201. When the limit component 202 rotates, it drives the ends of multiple groups of clamping components 203 to move closer to or away from the center of the circle. The clamping component 203 arranged on the limit component 202 can adjust the size of the space in the middle of the limit component 202.

[0034] In summary, by passing the brake through the middle part of the control component 201, and then using the control component 201 to drive the limit component 202 to operate, the limit component 202 drives multiple groups of clamping components 203 to deflect thereon during operation, and then the multiple groups of clamping components 203 can adjust the size of the space in the middle part of the control component 201, so that the clamping mechanism can be installed on generator brakes of different sizes, and then the operator pulls the linkage component 104 so that the linkage component 104 drives the rotating component 103 to operate, so that the extrusion component 105 is pressed vertically downward. During the vertical pressing process, the extrusion component 105 is located at the center of the bushing and fits with the upper surface of the bushing, so that the bushing is evenly stressed when entering the brake cylinder. The device will not cause manual clamping to fail to ensure that the applied pressure is uniform and appropriate, which is easy to damage the bushing or other components.

[0035] Example 2

[0036] Reference Figures 2-3, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a device for controlling a generator, which solves the problem that the bushing is subjected to uneven force and is easily damaged during installation. It includes a support assembly 102 including a connecting block 102a fixedly connected to two groups of brackets 101, a supporting block 102b fixedly connected between the two groups of connecting blocks 102a, and a groove 102c opened on the supporting block 102b.

[0037] Furthermore, the rotating assembly 103 includes a sector tooth 103a rotatably connected in the groove 102c, a rotating shaft 103b fixed to the sector tooth 103a, the rotating shaft 103b rotatably connected to the support block 102b, the sector tooth 103a rotatably connected in the groove 102c via the rotating shaft 103b, and a rotating arm 103c fixed to the sector tooth 103a.

[0038] Specifically, two groups of rotating components 103 are provided, and the two groups of rotating components 103 are distributed in mirror symmetry.

[0039] The two groups of sector teeth 103a mesh with each other. When one group of the two groups of sector teeth 103a rotates, the other group is driven to deflect.

[0040] Furthermore, the linkage assembly 104 includes a linkage block 104a hinged on one side of the rotating arm 103c, a tooth block 104b fixed to one end of the linkage block 104a, a connecting rod 104c fixed to one of the two groups of rotating arms 103c, and a handle 104d fixed to the connecting rod 104c.

[0041] When the operator presses down the handle 104d, the end of the rotating arm 103c away from the sector tooth 103a is driven to be pressed down, and the two sets of meshing sector teeth 103a are driven to rotate simultaneously, so that the linkage blocks 104a on the two sets of rotating arms 103c drop accordingly, and because the two sets of tooth blocks 104b are meshed with each other, the center of gravity of the two sets of linkage blocks 104a when pressed down is located between the two sets of tooth blocks 104b.

[0042] Furthermore, the extrusion assembly 105 includes a connecting shaft 105a fixedly connected to the gear block 104b, a fixed block 105b movably connected to the connecting shaft 105a, the connecting shaft 105a is rotatably connected to the middle of the fixed block 105b, and an extrusion block 105c movably connected to the bottom of the fixed block 105b, the bottom of the extrusion block 105c is ring-shaped and can be disassembled and replaced with a size matching the bushing.

[0043] In summary, when the operator presses down the handle 104d, the rotating arm 103c is driven to be pressed down away from the end of the sector tooth 103a, and the two sets of meshing sector teeth 103a are driven to rotate at the same time, and the linkage blocks 104a on the two sets of rotating arms 103c drop accordingly. Since the two sets of tooth blocks 104b are meshed with each other, the center of gravity of the two sets of linkage blocks 104a when pressed down is between the two sets of tooth blocks 104b. When the two sets of tooth blocks 104b are pressed down, the extrusion block 105c is driven to be pressed down, and the ring at the bottom of the extrusion block 105c fits with the top of the bushing and drives the bushing to be pressed down into the brake cylinder.

[0044] Example 3

[0045] Reference Figures 4 to 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a mounting device to solve the installation problem of the bushing clamping mechanism, which includes a control component 201 including a mounting ring 201a fixedly connected to the bottom of the bracket 101, a limit block 201b fixedly connected to the mounting ring 201a, a screw rod 201c threadedly connected to the limit block 201b, and an engaging block 201d threadedly connected to one end of the screw rod 201c.

[0046] Furthermore, the limiting assembly 202 includes a slider 202a fixed to the bottom of the engaging block 201d, a guide block 202b fixed between the slider 202a and the mounting ring 201a, the slider 202a is slidably connected to the guide block 202b, the guide block 202b is fixed to the mounting ring 201a, and a ring 202c fixed to the guide block 202b.

[0047] Wherein, due to the limiting reason of the guide block 202b, when the screw rod 201c rotates, the slider 202a drives the engaging block 201d to move on the screw rod 201c.

[0048] Furthermore, the clamping assembly 203 includes a plurality of rotating blocks 203a hinged on the circular ring 202c, a clamping rod 203b movably connected to the rotating block 203a, a rotating shaft 203c movably connected to one end of the clamping rod 203b, the clamping rod 203b rotatably connected to the rotating shaft 203c, the rotating shaft 203c fixedly connected to the mounting ring 201a, and an arc block 203d fixedly connected to one end away from the rotating shaft 203c.

[0049] Specifically, when the circular ring 202c rotates on the mounting ring 201a, the multiple groups of rotating blocks 203a deflect at the same time, which drives the clamping rod 203b to rotate on the rotating shaft 203c. The clamping rod 203b is slidably connected to the rotating block 203a, and the gaps between the multiple groups of arc blocks 203d also change accordingly.

[0050] In summary, the operator rotates the screw 201c. Due to the limit of the guide block 202b, when the screw 201c rotates, the slider 202a drives the meshing block 201d to move on the screw 201c, and the slider 202a drives the ring 202c to rotate around the center of the mounting ring 201a. At this time, the multiple groups of rotating blocks 203a deflect at the same angle. When the meshing block 201d moves to the end away from the limit block 201b, the deflection angle of the rotating block 203a is the largest, and the arc block 203d is close to the inner side of the ring 202c. At this time, the distance between the multiple groups of arc blocks 203d is the largest. On the contrary, when the meshing block 201d and the limit block 201b approach each other, the clamping rod 203b is driven to rotate on the rotating shaft 203c, and the clamping rod 203b is slidably connected to the rotating block 203a, and the gap between the multiple groups of arc blocks 203d also becomes smaller.

[0051] The operator can adjust the size between the arc blocks 203d by rotating the screw 201c to clamp brake cylinders of different sizes. After installation, the operator can rotate the screw 201c in the reverse direction so that the multiple groups of arc blocks 203d produce a reverse extrusion force on the brake cylinder, thereby better installing the device on the brake cylinder. The operator only needs to rotate the nut and then fix the nut, which is convenient and quick.
