[0035] Example 1
[0036] Reference Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides an adjustment mechanism, which can solve the problem that after the construction of the hydropower station is completed, the bridge crane cannot be hoisted using the sky anchor due to the influence of the sky anchor, the installation position of the generator set and the parking position of the adjacent bridge crane. It includes a frame component 100, a fixed component 200 arranged on the frame component 100, and an adjustment component 300 arranged on the fixed component 200; wherein the adjustment component 300 includes a moving component 301, a driving component 302 arranged on the moving component 301, and a rotating component 303 arranged on the driving component 302.
[0037] Specifically, the moving assembly 301 includes a moving plate 301a, a pulling plate 301b fixedly connected to the moving plate 301a, an inclined surface 301c arranged on the pulling plate 301b, a drawing groove 301d provided on the inclined surface 301c, a limiting groove 301e provided on the side of the drawing groove 301d, and a shifting groove 301f provided on the moving plate 301a. Both sides of the lower end of the pulling plate 301b are provided with inclined surfaces 301c, and both sides of the inclined surfaces 301c are provided with drawing grooves 301d and limiting grooves 301e. The width of the limiting groove 301e is greater than that of the pulling groove 301d. By providing the shifting groove 301f, the moving plate 301a can be easily moved. The driving assembly 302 includes a limiting block 302a, a pulling block 302b fixedly connected to the limiting block 302a, a pulling column 302c fixedly connected to the pulling block 302b, and a tooth groove 302d provided on the pulling column 302c. The limit block 302a is matched with the limit groove 301e, and the limit block 302a slides in the limit groove 301e. The pull block 302b is matched with the pull groove 301d, and the pull block 302b slides in the pull groove 301d. By making the width of the limit groove 301e larger than the pull groove 301d, and the width of the limit block 302a larger than the pull groove 301d, it is beneficial that when the limit block 302a and the pull block 302b slide, they will not be separated from the pull plate 301b. The rotating assembly 303 includes a rotating column 303a, a limit drive groove 303b provided on the rotating column 303a, a tooth block 303c fixedly connected to the limit drive groove 303b, and a connecting column 303d fixedly connected to the rotating column 303a. The diameter of the limit driving groove 303b is matched with the diameter of the pull column 302c, the tooth block 303c is matched with the tooth groove 302d, and the depth of the limit driving groove 303b is greater than the height of the tooth block 303c. When the tooth block 303c is engaged with the tooth groove 302d, the limit block 302a is located at the uppermost end of the limit groove 301e, and the pull block 302b is located at the uppermost end of the pull groove 301d. At this time, since the depth of the limit driving groove 303b is greater than the height of the tooth block 303c, The pull column 302c cannot move up and down. Therefore, when the pull plate 301b moves upward, the limit block 302a and the pull block 302b slide in the limit groove 301e and the pull groove 301d, and the limit groove 301e and the pull groove 301d on both sides of the inclined surface 301c drive the limit block 302a and the pull block 302b to move toward the middle at the same time, thereby causing the pull column 302c to move toward the center, thereby causing the tooth block 303c to disengage from the tooth groove 302d.
[0038] Furthermore, the fixing component 200 includes a corbel plate 201 and a connecting hole 202 provided on the corbel plate 201. The frame component 100 includes a main beam frame 101, a column frame 102 connected to the main beam frame 101, a moving groove 103 provided on the column frame 102, an electric chain hoist 104 provided on the main beam frame 101, and a hook frame 105 provided on the main beam frame 101. The connecting column 303d is fixedly connected to the corbel plate 201 through the connecting hole 202, the column frame 102 is a hollow grooved concave plate, the rotating column 303a is rotatably connected to the column frame 102, the movable plate 301a is adapted to the movable groove 103, and the movable plate 301a slides in the movable groove 103. When the tooth block 303c is engaged with the tooth groove 302d, the movable plate 301a is located at the lower end of the movable groove 103. At this time, the pull column 302c cannot rotate due to the restriction of the limiting block 302a and the pull plate 301b. Therefore, when the tooth block 303c is engaged with the tooth groove 302d, the rotating column 303a is restricted by the pull column 302c and cannot rotate either.
[0039] When in use, when the gantry needs to be fixed on the web of the bridge crane main beam, the staff moves the moving plate 301a upward in the moving groove 103 through the shifting groove 301f, and the moving plate 301a moves upward to drive the pulling plate 301b to move upward, and the pulling plate 301b moves upward to drive the limit blocks 302a and the pulling blocks 302b on both sides of the inclined surface 301c to slide in the limit groove 301e and the pulling groove 301d. Since the limit driving groove 303b restricts the pulling column 302c to move left and right, the limit blocks 302a and the pulling blocks 302 b moves toward the center, thereby driving the pulling column 302c to move toward the center. When the moving plate 301a moves to the uppermost part of the moving groove 103, at this time, the limit block 302a and the pulling block 302b are located at the lowermost end of the limit groove 301e and the pulling groove 301d. At this time, the tooth groove 302d on the pulling column 302c is separated from the tooth block 303c on the rotating column 303a. At this time, the rotating column 303a is not restricted by the pulling column 302c, and the rotating column 303a can rotate at an angle, and at this time, the corbel plate 201 can move The bracket plate 201 rotates, the connecting column 303d rotates, and the connecting column 303d rotates and drives the rotating plate to rotate. After the bracket plate 201 rotates to the required position, the movable plate 301a is released, and the movable plate 301a falls to the lower end of the movable groove 103 under the action of gravity. At this time, the pulling plate 301b follows the movable plate 301a to fall, and then drives the limit block 302a and the pulling block 302b to slide in the limit groove 301e and the pulling groove 301d while moving outward, and the pulling block 302b moves outward to drive the pulling column 302c to Move outward, when the pulling block 302b moves to the uppermost end of the pulling groove 301d, the pulling column 302c enters the limiting driving groove 303b, and the tooth groove 302d engages with the tooth block 303c. At this time, the rotating column 303a is restricted and cannot rotate, and then the position of the corbel plate 201 is fixed. Then the staff connects the corbel plate 201 to the web of the bridge crane main beam to provide a lifting point and lifting force for the bridge crane trolley. When the bridge crane trolley needs to be dismantled and reinstalled, the trolley is lifted off and lifted back to the bridge crane trolley track by the hook of the electric chain hoist 104.
[0040] In summary, the fixing component 200 is moved to a suitable position through the adjusting component 300, and then the fixing component 200 is connected to the web of the bridge crane main beam, and the bridge crane trolley is provided with a lifting point and lifting force through the frame component 100, so that the bridge crane trolley can be easily dismantled or moved.
[0041] Example 2
[0042] Reference Figures 1 to 4, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a locking component 304, through which the position of the moving component 301 can be locked, so that the staff can adjust the position of the fixed component 200. The adjusting component 300 also includes a locking component 304; the locking component 304 includes a locking block 304a, an extruded surface 304b arranged on the locking block 304a, a sliding rod 304c fixedly connected to the locking block 304a, and a locking spring 304d fixedly connected to the locking block 304a.
[0043] Furthermore, the work frame component 100 also includes a locking groove 106 provided on the side of the moving groove 103, and a sliding groove 107 provided on the side of the locking groove 106; the moving assembly 301 also includes a locking support groove 301g provided on the moving plate 301a. The locking block 304a is adapted to the locking groove 106, one end of the locking spring 304d is fixedly connected to the locking groove 106, the other end of the locking spring 304d is fixedly connected to the locking block 304a, and the sliding rod 304c is placed in the sliding groove 107 to slide. When the locking spring 304d is in a normal state, the sliding rod 304c is located at the front end of the sliding groove 107. At this time, a small end of the locking block 304a is located in the locking groove 106, and a large end of the locking block 304a is located in the moving groove 103. The locking block 304a is conveniently squeezed into the locking groove 106 through the squeezing surface 304b.
[0044] When in use, when the gantry needs to be fixed on the web of the bridge crane main beam, the staff moves the moving plate 301a upward in the moving groove 103 through the moving groove 301f. When the moving plate 301a moves upward and contacts the extrusion surface 304b on the locking block 304a, the extrusion force generated by the extrusion surface 304b squeezes the locking block 304a into the locking groove 106. At this time, the locking spring 304d contracts, and the sliding rod 304c slides in the slide groove 107 to the rear end of the slide groove 107. When the moving plate 301a moves to the uppermost end of the moving groove 103, the locking support groove 301g is aligned with the locking block 304a. At this time, the locking spring 304d resets and extends to drive the locking block 304a to move toward the moving groove 103. When the locking plate 301a is in the locked state, the locking block 304a is moved to the locking groove 301g, and the locking plate 301a is completely moved out of the locking groove 301g and into the locking groove 106. At this time, the movable plate 301a is reset by gravity, and the position of the corbel plate 201 is fixed.
[0045] Example 3
[0046] Reference Figures 5 to 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a gantry for hoisting a bridge crane trolley in an underground powerhouse of a hydropower station, solving the problem that the height of the gantry cannot be adjusted, and includes the adjustment mechanism in the above embodiment, including a telescopic component 400; the telescopic component 400 is arranged on a tooling component; the tooling component also includes an arc block 108108, a rotating hole 109, and a clamping groove 110. The arc block 108 is fixedly connected to the column frame 102, the rotating hole 109 is provided on the side end of the main beam frame 101, the clamping groove 110 is provided on the side of the rotating hole 109, and a plurality of clamping grooves 110 are provided around the rotating hole 109.
[0047] Further, the telescopic component 400 includes a telescopic column 401, an arc groove 402 provided on the telescopic column 401, a rectangular groove 403 provided on the telescopic column 401, a shaft 404 fixedly connected in the rectangular groove 403, a block 405 movably connected to the shaft 404, and an outer plate 406 provided on the frame component 100. The telescopic column 401 is placed at the hollow slot of the column frame 102, the arc block 108 is placed in the arc groove 402 for sliding, the outer plate 406 is fixedly connected to the main beam frame 101, the outer plate 406 is slidably connected to the column frame 102, the block 405 is adapted to the slot 110, and by providing a plurality of slots 110, the height of the gantry can be adjusted to a desired position for locking. When the column frame 102 and the rope column are in a relatively locked state, the block 405 is horizontally placed in the slot 110.
[0048] When in use, when it is necessary to adjust the height of the gantry, the staff rotates the block 405, and when the block 405 is rotated upward to a vertical state, the block 405 disengages from the slot 110. At this time, by rotating the block 405, the block 405 rotates to drive the shaft 404 to rotate, and the shaft 404 rotates to drive the arc groove 402 to rotate, and then due to the restriction of the outer plate 406 on the column frame 102, the column frame 102 can only move up and down, and then the arc block 108 moves up and down in the arc groove 402 at this time. When the column frame 102 moves to the required position, stop rotating the block 405, and then rotate the block 405 downward so that the block 405 enters the slot 110. At this time, the block 405 cannot rotate, and then the relative position of the column frame 102 and the shaft 404 is locked, and the height adjustment of the gantry is completed.
[0049] In summary, by adjusting the relative positions of the shaft 404 and the column frame 102, the gantry can be adjusted to a suitable height, so that the bridge crane trolley can be operated conveniently after the gantry is connected to the web of the bridge crane main beam.
