Description

Technical Field

[0001] The utility model belongs to the technical field of bottom shaft gates, and in particular relates to a support control locking mechanism for a bottom shaft gate. Background Art

[0002] The bottom-axis rotating gate, also known as the hydraulically driven bottom-axis rotating steel gate or steel dam gate, is a special gate structure. A swing arm is fixed at the end of the bottom axis of the gate, and the swing arm is connected to a working cylinder to drive the gate to rotate. After the gate opening is adjusted into place, the gate position needs to be fixed by a locking mechanism to avoid long-term loading of the working cylinder.

[0003] At present, a support rod is installed on one side of the bottom axis rotating gate. When the gate is opened, the support rod on one side adjusts the support point of the support rod through the telescopic driving mechanism. After the support point is adjusted, the end of the support rod can abut against the limit block in its movement path, thereby limiting the rotation of the swing arm and the gate and playing a supporting locking role. By controlling the limit blocks at different positions to move to the movement path of the support rod and making the support rod abut against the limit blocks at different positions, locking of different gates at different openings can be achieved. However, adjustment in this way requires cooperation between multiple limit blocks and a large number of driving mechanisms, resulting in high cost and complex control. Utility Model Content

[0029] A bottom axis gate support and control locking mechanism comprises a river channel foundation 1 and a gate body 2, the gate body 2 is located inside the river channel foundation 1, a gate bottom axis 3 is fixed to the bottom of the gate body 2, an opening and closing device 4 is installed on the outside of the river channel foundation 1, and the output shaft of the opening and closing device 4 passes through the river channel foundation 1 and is fixedly connected to the gate bottom axis 3, support and control struts 5 are hinged on the front and rear sides of the right side of the gate body 2, a tooth plate 6 is fixed below the right side of the gate body 2, and a linkage structure 7 is arranged on the right side of the tooth plate 6, a support frame 8 is fixed on the right side of the bottom of the inner wall of the river channel foundation 1, a movable block 9 is slidably connected to the inside of the support frame 8, a driving structure 10 is movably connected to the inside of the support frame 8, through grooves 11 are opened on the front and rear sides of the top of the support frame 8, and one end of the support and control strut 5 passes through the through groove 11 and is hinged to the top of the movable block 9, and a positioning structure 12 is arranged on the top of the support frame 8.

[0030] The linkage structure 7 includes a first gear 71, a driving wheel 72, a driven wheel 73 and a rotating rod 74. The first gear 71 is arranged on the right side of the tooth plate 6, and the first gear 71 is meshed with the tooth plate 6. The first gear 71 is rotatably connected to the surface of the inner wall of the river channel foundation 1. The driving wheel 72 is fixed on the front side of the first gear 71. The driven wheel 73 is arranged below the driving wheel 72, and the driven wheel 73 is connected to the driving wheel 72 through a belt. The driven wheel 73 is rotatably connected to the inner wall of the river channel foundation 1, and the rotating rod 74 is fixed on the front side of the driven wheel 73. The driving structure 10 includes a threaded rod 101, a first bevel gear 102 and a second bevel gear 103. The threaded rod 101 is rotatably connected to the support frame Inside the gear 71, the first bevel gear 102 is fixed to the left side of the surface of the threaded rod 101, and the second bevel gear 103 is fixed to the front end of the rotating rod 74, and the first bevel gear 102 is meshed with the second bevel gear 103, and the threaded rod 101 passes through the movable block 9 and is threadedly connected with the movable block 9. When the first gear 71 rotates, the driving wheel 72 rotates the driven wheel 73 below through the belt, and the rotating rod 74 drives the second bevel gear 103 to rotate. Since the second bevel gear 103 is meshed with the first bevel gear 102, and then the threaded rod 101 rotates, the movable block 9 will move to the right so that the support rod 5 can change the support point according to the inclination angle of the gate body 2.

[0031] The positioning structure 12 includes a waterproof hydraulic cylinder 121, a positioning plate 122 and a positioning groove 123. The waterproof hydraulic cylinder 121 is fixed to the left side of the top of the supporting frame 8, and the positioning plate 122 is slidably connected to the right side of the top of the supporting frame 8. The positioning groove 123 is opened at the front and rear sides of the left surface of the positioning plate 122, and the output shaft of the waterproof hydraulic cylinder 121 is fixedly connected to the positioning plate 122. The positioning groove 123 corresponds to the position of the through groove 11, and the width of the inner wall of the positioning groove 123 is the same as the width of the inner wall of the through groove 11. When the adjustment of the support and control strut 5 is completed, the staff opens the waterproof hydraulic cylinder 121, thereby moving the positioning plate 122 to the left side. As the positioning plate 122 continues to move, the support and control strut 5 enters the interior of the positioning groove 123, and the position of the support and control strut 5 is locked by the positioning plate 122.

[0032] Guide grooves 13 are provided on both the front and rear sides of the bottom of the inner wall of the support frame 8, and guide blocks 14 are fixed on both the front and rear sides of the bottom of the movable block 9. The guide blocks 14 are located inside the guide grooves 13 and are slidably connected to the inner walls of the guide grooves 13. When the movable block 9 moves inside the support frame 8, the guide blocks 14 also slide inside the guide grooves 13. The movable block 9 is guided by the guide blocks 14 to improve the stability of the movable block 9 when it moves left and right.

[0033] The tooth plate 6 is arranged in a semicircular shape as a whole, and the center of the tooth plate 6 is at the same position as the center of the gate bottom shaft 3. When the gate body 2 tilts to the right, the tooth plate 6 will move to drive the first gear 71 to rotate and adjust the subsequent support points.

[0034] Working principle: when the bottom shaft valve is opened, the staff will open the opening and closing device 4, so that the opening and closing device 4 drives the gate bottom shaft 3 to rotate, so that the gate body 2 tilts to the right, and the tooth plate 6 also moves. The threaded rod 101 inside the support frame 8 rotates synchronously, and the movable block 9 drives the upper support and control strut 5 to move to the right. According to the continuous tilt of the gate body 2, the supporting point of the support and control strut 5 is adjusted synchronously. When the gate body 2 stops moving, the waterproof hydraulic cylinder 121 above the support frame 8 will open, and the positioning plate 122 will move to the left, so that the support and control strut 5 enters the positioning groove 123 on the surface of the positioning plate 122, and the support and control strut 5 is locked so that the support and control strut 5 can stably support the gate body 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
