Description

Technical Field

[0001] The utility model relates to the technical field of docking positioning of hydropower stations, and more specifically, to a new type of hydraulic grab beam positioning support rod. Background Art

[0002] For the positioning between the hydraulic grab beam of the gantry crane in the hydropower station and the gate, positioning pin rods are often installed on the gate. A positioning support rod for feedback on the connection between the grab beam and the gate is installed on the grab beam. Currently, this grab beam positioning support rod is a round steel bar with a diameter of about 5 cm. During daily use, it is pushed by the positioning pin rod on the gate and moved to the upper proximity switch to output the connection-in-place signal. However, due to its too small contact surface, it is easy for the positioning support rod to deflect, causing skew between the positioning support rod and the positioning pin rod and jamming in the grab beam positioning sleeve, resulting in the inability to output a normal in-place signal. Summary of the Utility Model

[0003] The utility model aims to provide a new type of hydraulic grab beam positioning support rod to solve the problems in the prior art that the contact surface between the positioning support rod and the positioning pin rod is too small, prone to deflection, and prone to jamming in the sleeve, resulting in the inability to output a normal in-place signal.

[0004] The embodiments of the utility model are implemented as follows:

[0005] The embodiment of the utility model provides a new type of hydraulic grab beam positioning support rod, which includes a hydraulic automatic grab beam and a maintenance gate;

[0006] At both ends of the above-mentioned hydraulic automatic grab beam, a first positioning member and a second positioning member are respectively provided. Inside the above-mentioned first positioning member and the above-mentioned second positioning member, a first positioning support rod and a second positioning support rod are respectively provided. The above-mentioned first positioning support rod and the above-mentioned second positioning support rod slide along the axes of the above-mentioned first positioning member and the above-mentioned second positioning member respectively. At the ends of the above-mentioned first positioning member and the above-mentioned second positioning member away from the above-mentioned first positioning support rod and the above-mentioned second positioning support rod, a first induction switch and a second induction switch are respectively provided. Both the above-mentioned first induction switch and the above-mentioned second induction switch are electrically connected to the control room operation console;

[0007] At the two top ends of the above-mentioned maintenance gate, a first positioning pin rod and a second positioning pin rod are respectively provided. One end of the above-mentioned first positioning support rod close to the above-mentioned maintenance gate is fixedly connected with a first disc, and one side of the above-mentioned first disc close to the above-mentioned maintenance gate abuts against the top end of the above-mentioned first positioning pin rod. One end of the above-mentioned second positioning support rod close to the above-mentioned maintenance gate is fixedly connected with a second disc, and one side of the above-mentioned second disc close to the above-mentioned maintenance gate abuts against the top end of the above-mentioned second positioning pin rod.

[0008] In use, first, the crane hoists the above-mentioned hydraulic automatic grab beam to the top of the above-mentioned maintenance gate. The first positioning pin rod and the second positioning pin rod are docked through the above-mentioned first positioning member and the above-mentioned second positioning member, so that the first disc of the above-mentioned first positioning strut abuts against the top end of the above-mentioned first positioning pin rod, and the second disc of the above-mentioned second positioning strut abuts against the top end of the above-mentioned second positioning pin rod. Then, the crane slowly lowers the above-mentioned hydraulic automatic grab beam. Under the action of gravity, the above-mentioned first positioning strut and the above-mentioned second positioning strut are respectively jacked up and moved upward by the above-mentioned first positioning pin rod and the above-mentioned second positioning pin rod. When the ends of the above-mentioned first positioning strut and the above-mentioned second positioning strut away from the above-mentioned maintenance gate respectively move to the above-mentioned first induction switch and the above-mentioned second induction switch, the above-mentioned first induction switch and the above-mentioned second induction switch immediately sense and transmit signals to the control room operation console. The control room operation console receiving the in-place signal of the above-mentioned hydraulic automatic grab beam indicates that the above-mentioned hydraulic automatic grab beam has been in place. Finally, by locking the above-mentioned maintenance gate and the above-mentioned hydraulic automatic grab beam, they are connected into one body, facilitating the lifting and lowering of the above-mentioned maintenance gate.

[0009] A new type of hydraulic grab positioning strut disclosed in this implementation scheme increases the bottom contact area of the above-mentioned first positioning strut and the above-mentioned second positioning strut by setting the first disc and the second disc, and can prevent the above-mentioned first positioning strut and the above-mentioned second positioning strut from being skewed and overlapping respectively when docking with the above-mentioned first positioning pin rod and the above-mentioned second positioning pin rod. Furthermore, a new type of hydraulic grab positioning strut has the beneficial effects of increasing the contact surface between the positioning strut and the positioning pin rod, being not easily skewed, not easily getting stuck in the sleeve, and being able to realize the output of normal in-place signals.

[0010] Optionally: The above-mentioned first positioning member has a first outer shell body, and a first long hole is opened on the axis of the first outer shell body, and the above-mentioned first positioning strut is located inside the first long hole.

[0011] With such a setting, it is convenient for the above-mentioned first positioning strut to expand and contract axially in the first long hole.

[0012] Optionally: The above-mentioned first induction switch is fixedly connected to the bottom end of the first long hole.

[0013] With such a setting, when the end of the above-mentioned first positioning strut close to the above-mentioned first induction switch moves to the above-mentioned first induction switch, the above-mentioned first induction switch immediately senses and transmits a signal to the control room operation console. The control room operation console receiving the signal indicates that the above-mentioned first positioning member of the above-mentioned hydraulic automatic grab beam has been in place, facilitating the locking of the above-mentioned maintenance gate and thus facilitating the lifting of the above-mentioned maintenance gate.

[0014] Optionally, a second housing is provided at one end of the first housing away from the hydraulic automatic grab beam. The second housing is detachably connected to one end of the first housing away from the hydraulic automatic grab beam, and the first positioning pin rod is located inside the second housing.

[0015] With such a setting, the second housing effectively protects the first positioning pin rod. At the same time, the second housing also facilitates the quick docking of the first positioning strut to the first positioning pin rod, improving the docking efficiency.

[0016] Optionally, a first positioning sleeve is provided axially inside the first housing and the second housing. Both the first positioning strut and the first positioning pin rod are located inside the first positioning sleeve.

[0017] With such a setting, the first positioning sleeve can effectively play a guiding role, facilitating the docking of the first positioning strut and the first positioning pin rod.

[0018] Optionally, the diameter of the first disc is greater than the diameter of the first positioning pin rod, and the diameter of the first disc is less than the inner diameter of the first positioning sleeve.

[0019] With such a setting, by setting the first disc, the contact surface between the bottom of the first positioning strut and the top of the first positioning pin rod is increased, which can effectively prevent the first positioning strut from being skewed and overlapping and squeezing inside the first positioning sleeve when contacting the first positioning pin rod, effectively avoiding the phenomenon that the first positioning member of the hydraulic automatic grab beam cannot be properly in place when lifting and lowering the maintenance gate.

[0020] Optionally, the second positioning member has a third housing. A second long hole is provided on the axis of the third housing. The second positioning strut is located inside the second long hole, and the second induction switch is fixedly connected to the bottom end of the second long hole.

[0021] With such a setting, it is convenient for the second positioning strut to expand and contract axially in the second long hole. When one end of the second positioning strut close to the second induction switch moves to the second induction switch, the second induction switch immediately senses and transmits a signal to the control room operation console. The control room operation console receiving the signal indicates that the second positioning member of the hydraulic automatic grab beam has been in place, facilitating the locking of the maintenance gate and thus facilitating the lifting of the maintenance gate.

[0022] Optionally, a fourth housing is provided at one end of the third housing away from the hydraulic automatic grab beam. The fourth housing is detachably connected to one end of the third housing away from the hydraulic automatic grab beam, and the second positioning pin rod is located inside the fourth housing.

[0023] With such a setting, the above-mentioned fourth outer casing effectively protects the above-mentioned second positioning pin rod. At the same time, the above-mentioned fourth outer casing also facilitates the rapid docking of the above-mentioned second positioning strut with the above-mentioned second positioning pin rod, improving the docking efficiency.

[0024] Optionally: A second positioning sleeve is provided axially inside the above-mentioned third outer casing and the above-mentioned fourth outer casing, and both the above-mentioned second positioning strut and the above-mentioned second positioning pin rod are located inside the above-mentioned second positioning sleeve.

[0025] With such a setting, the above-mentioned second positioning sleeve can effectively play a guiding role, facilitating the docking of the above-mentioned second positioning strut with the above-mentioned second positioning pin rod.

[0026] Optionally: The diameter of the above-mentioned second disc is greater than the diameter of the above-mentioned second positioning pin rod, and the diameter of the above-mentioned second disc is less than the inner diameter of the above-mentioned second positioning sleeve.

[0027] With such a setting, by setting the above-mentioned second disc, the contact surface between the bottom of the above-mentioned second positioning strut and the top of the above-mentioned second positioning pin rod is increased, which can effectively prevent the above-mentioned second positioning strut from being skewed and overlapping and squeezing inside the above-mentioned second positioning sleeve when contacting the above-mentioned second positioning pin rod, effectively avoiding the phenomenon that the above-mentioned second positioning member of the above-mentioned hydraulic automatic grab beam cannot reach the normal position when lifting and lowering the above-mentioned maintenance gate.

[0028] Based on the above description, a new type of hydraulic grab beam positioning strut disclosed by the present utility model has the beneficial effects of increasing the contact surface between the positioning strut and the positioning pin rod, being not easily skewed, not easily generating jams inside the sleeve, and being able to output a normal in-place signal.

[0036] Embodiment

[0037] See Figure 1 、 Figure 2 and Figure 3 , this embodiment proposes a new type of hydraulic grab beam positioning strut, including a hydraulic automatic grab beam 1 and a maintenance gate 2;

[0038] The two ends of the hydraulic automatic grab beam 1 are respectively provided with a first positioning member 3 and a second positioning member 4. The first positioning strut 5 and the second positioning strut 6 are respectively arranged inside the first positioning member 3 and the second positioning member 4. The first positioning strut 5 and the second positioning strut 6 slide along the axes of the first positioning member 3 and the second positioning member 4 respectively. The first induction switch 7 and the second induction switch 8 are respectively arranged at the ends of the first positioning member 3 and the second positioning member 4 far from the first positioning strut 5 and the second positioning strut 6. Both the first induction switch 7 and the second induction switch 8 are electrically connected to the control room operation console (not shown in the figure);

[0039] At both ends of the top of the maintenance gate 2, a first positioning pin rod 9 and a second positioning pin rod 10 are respectively provided. One end of the first positioning support rod 5 close to the maintenance gate 2 is fixedly connected with a first disc 11. One side of the first disc 11 close to the maintenance gate 2 abuts against the top end of the first positioning pin rod 9. One end of the second positioning support rod 6 close to the maintenance gate 2 is fixedly connected with a second disc 12. One side of the second disc 12 close to the maintenance gate 2 abuts against the top end of the second positioning pin rod 10.

[0040] During use, first, the crane hoists the hydraulic automatic grab beam 1 to the top of the maintenance gate 2. The first positioning member 3 and the second positioning member 4 are used to dock with the first positioning pin rod 9 and the second positioning pin rod 10, so that the first disc 11 of the first positioning support rod 5 abuts against the top end of the first positioning pin rod 9, and the second disc 12 of the second positioning support rod 6 abuts against the top end of the second positioning pin rod 10. Then, the crane slowly lowers the hydraulic automatic grab beam 1. Under the action of gravity, the first positioning support rod 5 and the second positioning support rod 6 are respectively jacked up and moved upward by the first positioning pin rod 9 and the second positioning pin rod 10. When the ends of the first positioning support rod 5 and the second positioning support rod 6 far from the maintenance gate 2 respectively move to the first induction switch 7 and the second induction switch 8, the first induction switch 7 and the second induction switch 8 immediately sense and transmit signals to the control room operation console. The control room operation console receiving the in-place signal of the hydraulic automatic grab beam 1 indicates that the hydraulic automatic grab beam 1 has been in place. Finally, by locking the maintenance gate 2 and the hydraulic automatic grab beam 1, they are connected into one body, facilitating the lifting and lowering of the maintenance gate 2.

[0041] A new type of hydraulic grab positioning support rod disclosed in this implementation scheme has the first disc 11 and the second disc 12 provided, which increases the bottom contact area of the first positioning support rod 5 and the second positioning support rod 6, and can prevent the first positioning support rod 5 and the second positioning support rod 6 from being skewed and overlapping respectively when docking with the first positioning pin rod 9 and the second positioning pin rod 10. Furthermore, the new type of hydraulic grab positioning support rod has the beneficial effects of increased contact area between the positioning support rod and the positioning pin rod, not being prone to skewing, not being prone to jamming in the sleeve, and being able to realize normal in-place signal output.

[0042] See Figure 1 、 Figure 2 and Figure 3 As shown in, the first positioning member 3 has a first outer shell 13. A first long hole 14 is opened on the axis of the first outer shell 13. The first positioning support rod 5 is located inside the first long hole 14, which facilitates the telescopic movement of the first positioning support rod 5 in the axial direction of the first long hole 14.

[0043] The first induction switch 7 is fixedly connected to the bottom end of the first long hole 14. When the end of the first positioning strut 5 close to the first induction switch 7 moves to the position of the first induction switch 7, the first induction switch 7 immediately senses and transmits a signal to the control room operation console. The control room operation console receiving the signal indicates that the first positioning member 3 of the hydraulic automatic grab beam 1 has been in place, facilitating the locking of the maintenance gate 2 and thus facilitating the lifting of the maintenance gate 2.

[0044] One end of the first outer housing 13 away from the hydraulic automatic grab beam 1 is provided with a second outer housing 15. The second outer housing 15 is detachably connected to one end of the first outer housing 13 away from the hydraulic automatic grab beam 1. The first positioning pin rod 9 is located inside the second outer housing 15. The second outer housing 15 effectively protects the first positioning pin rod 9. At the same time, the second outer housing 15 also facilitates the quick docking of the first positioning strut 5 with the first positioning pin rod 9, improving the docking efficiency.

[0045] An axially arranged first positioning sleeve 16 is provided inside the first outer housing 13 and the second outer housing 15. Both the first positioning strut 5 and the first positioning pin rod 9 are located inside the first positioning sleeve 16. The first positioning sleeve 16 can effectively play a guiding role, facilitating the docking of the first positioning strut 5 with the first positioning pin rod 9.

[0046] The diameter of the first disc 11 is larger than the diameter of the first positioning pin rod 9, and the diameter of the first disc 11 is smaller than the inner diameter of the first positioning sleeve 16. By setting the first disc 11, the contact surface between the bottom of the first positioning strut 5 and the top of the first positioning pin rod 9 is increased, which can effectively prevent the first positioning strut 5 from being skewed and overlapping and squeezing inside the first positioning sleeve 16 when contacting the first positioning pin rod 9, effectively avoiding the phenomenon that the first positioning member 3 of the hydraulic automatic grab beam 1 cannot reach the normal position when lifting and lowering the maintenance gate 2.

[0047] See Figure 1 、 Figure 2 and Figure 3 , the second positioning member 4 has a third outer housing 17. A second long hole 18 is opened at the axis center of the third outer housing 17. The second positioning strut 6 is located inside the second long hole 18. The second induction switch 8 is fixedly connected to the bottom end of the second long hole 18. This facilitates the telescopic movement of the second positioning strut 6 in the axial direction of the second long hole 18. When the end of the second positioning strut 6 close to the second induction switch 8 moves to the position of the second induction switch 8, the second induction switch 8 immediately senses and transmits a signal to the control room operation console. The control room operation console receiving the signal indicates that the second positioning member 4 of the hydraulic automatic grab beam 1 has been in place, facilitating the locking of the maintenance gate 2 and thus facilitating the lifting of the maintenance gate 2.

[0048] At one end of the third outer casing 17 away from the hydraulic automatic grab beam 1, there is a fourth outer casing 19. The fourth outer casing 19 is detachably connected to one end of the third outer casing 17 away from the hydraulic automatic grab beam 1. The second positioning pin rod 10 is located inside the fourth outer casing 19. The fourth outer casing 19 effectively protects the second positioning pin rod 10. At the same time, the fourth outer casing 19 also facilitates the quick docking of the second positioning support rod 6 with the second positioning pin rod 10, improving the docking efficiency.

[0049] Inside the third outer casing 17 and the fourth outer casing 19, there is a second positioning sleeve 20 axially. Both the second positioning support rod 6 and the second positioning pin rod 10 are located inside the second positioning sleeve 20. The second positioning sleeve 20 can effectively play a guiding role, facilitating the docking of the second positioning support rod 6 with the second positioning pin rod 10.

[0050] The diameter of the second disc 12 is larger than the diameter of the second positioning pin rod 10, and the diameter of the second disc 12 is smaller than the inner diameter of the second positioning sleeve 20. By setting the second disc 12, the contact surface between the bottom of the second positioning support rod 6 and the top of the second positioning pin rod 10 is increased, which can effectively prevent the second positioning support rod 6 from being skewed and overlapping and squeezing inside the second positioning sleeve 20 when contacting the second positioning pin rod 10, effectively avoiding the phenomenon that the second positioning component 4 of the hydraulic automatic grab beam 1 cannot reach the normal position when lifting and lowering the maintenance gate 2.

[0051] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, several grab beam lifting lugs 21 are provided at the top of the hydraulic automatic grab beam 1. The several grab beam lifting lugs 21 can connect the steel wire ropes of the lifting equipment, facilitating the lifting operation of the hydraulic automatic grab beam 1.

[0052] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, symmetrically arranged locking devices 22 are installed at the bottom end of the hydraulic automatic grab beam 1. The locking devices 22 have a first clamping piece 23 and a second clamping piece 24. An electrically driven pin shaft 25 is provided on the outside of the second clamping piece 24. Symmetrically arranged gate lifting lugs 26 are provided at the top end of the maintenance gate 2. The gate lifting lugs 26 are embedded between the first clamping piece 23 and the second clamping piece 24. The pin shaft 25 sequentially passes through the second clamping piece 24, the gate lifting lug 26, and the first clamping piece 23 under the condition of electric drive, effectively realizing the mutual connection between the hydraulic automatic grab beam 1 and the maintenance gate 2, facilitating the lifting and lowering movement of the maintenance gate 2.

[0053] See Figure 1 、 Figure 2 and Figure 3, the specific usage method of the new hydraulic grab beam positioning strut in this embodiment: First, the crane hoists the hydraulic automatic grab beam 1 to the top of the maintenance gate 2, and the second outer shells 15 and 19 of the first positioning member 3 and the second positioning member 4 are respectively docked with the first positioning pin 9 and the second positioning pin 10. The first positioning pin 9 and the second positioning pin 10 respectively penetrate inside the first positioning sleeve 16 and the second positioning sleeve 20, so that the first disc 11 of the first positioning strut 5 abuts against the top of the first positioning pin 9, and the second disc 12 of the second positioning strut 6 abuts against the top of the second positioning pin 10;

[0054] Then, the crane slowly lowers the hydraulic automatic grab beam 1. Under the action of gravity, the first positioning strut 5 and the second positioning strut 6 are respectively jacked up by the first positioning pin 9 and the second positioning pin 10, so that the first positioning strut 5 and the second positioning strut 6 move respectively in the first long hole 14 of the first outer shell 13 and the second long hole 18 of the third outer shell 17. When the ends of the first positioning strut 5 and the second positioning strut 6 far away from the maintenance gate 2 respectively move to the first induction switch 7 and the second induction switch 8, the first induction switch 7 and the second induction switch 8 immediately sense and transmit signals to the control room operation console. The control room operation console receiving the in-place signal of the hydraulic automatic grab beam 1 indicates that the hydraulic automatic grab beam 1 has been in place;

[0055] Finally, the maintenance gate 2 and the hydraulic automatic grab beam 1 are connected into one body through the locking device 22, which is convenient for lifting and lowering the maintenance gate 2.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
