Description

Technical Field

[0001] The present invention relates to the technical field of bridge crane position detection and positioning, in particular to a bridge crane position detection and positioning device for a hydropower station powerhouse. Background Art

[0002] Lifting equipment is essential machinery for hydropower generation. The safety and reliability of hydropower unit maintenance directly impacts the healthy and stable operation of the units, and is also directly related to the economic benefits of power generation companies. Hydropower unit maintenance involves numerous risks during lifting operations. For example, when lifting major equipment such as rotors, turbines, and top covers, numerous personnel are required to monitor and inspect the equipment from above and below to ensure comprehensive visibility for collisions and clearances with fixed components. This poses a significant safety hazard.

[0003] A Chinese patent with announcement number CN214243517U discloses a bridge crane with an anti-collision function. The output shaft of the second drive motor is connected to the active trolley wheel in a driving manner. The left and right ends of the top of the trolley frame are fixedly connected to symmetrically arranged support rods, which are arranged vertically upward. Laser ranging sensors are installed on the top of the two support rods. The left and right ends of the top of the main beam are fixedly connected to vertically arranged mounting plates. Laser receivers corresponding to the two laser ranging sensors are respectively fixed on the upper inner sides of the two mounting plates. The laser ranging sensors are connected to the PLC controller in the crane control circuit through wires.

[0004] The bridge crane in the above-mentioned prior art is equipped with a laser distance measuring sensor and a laser receiver, and the laser distance measuring sensor is connected to the PLC controller through a wire. The laser distance measuring sensor irradiates the laser onto the laser receiver and receives the light reflected by the laser receiver to monitor the distance between the trolley frame and the mounting plate in real time. When the distance between the two reaches the set mark, the laser distance measuring sensor feeds back the signal to the PLC controller, and the PLC controller can detect and locate the position of the bridge crane trolley frame on the trolley through calculation. However, the laser distance measuring sensor of the bridge crane in the prior art is not very effective in actual use. We found that there are still some shortcomings. For example, the bridge crane is generally installed at a relatively high position in the hydropower station plant, and the traditional structure of the laser ranging sensor is mainly installed and fixed by a large number of screws. Special disassembly tools are required for disassembly and assembly. Therefore, when the laser ranging sensor fails and needs maintenance or replacement and disassembly, it is still troublesome to operate at a high place. Secondly, the traditional bridge crane laser ranging sensor generally does not have a heat dissipation structure, so the airflow at the upper end of the hydropower station plant space is relatively hot, which also has a certain impact on the bridge crane laser ranging sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, in the present invention, the heat dissipation fins are installed inside the upper end of the laser ranging sensor body, which can absorb the heat emitted by the electronic components inside the laser ranging sensor body and dissipate the heat through the heat dissipation fins on the fin seat.

[0017] Secondly, in the present invention, the connecting seat at the lower end of the laser ranging sensor body is inserted along one side of the limiting groove notch of the support column. During the insertion process, the insertion portion of the connecting seat presses the inclined surface of the first clamping block, so that the first movable plate connected to the first clamping block slides inside the installation cavity and compresses the first spring until the connecting seat is inserted and the first clamping block corresponds to the position of the first clamping groove at the lower end of the connecting seat. At this time, the clamping end of the first clamping block can be clamped into the first clamping groove to fix the connecting seat under the reset effect of the first spring at the lower end of the first movable plate. When disassembling the laser ranging sensor body, it is only necessary to use the pull handle at the groove of the support column to pull the pull rod so that the first clamping block at the first movable plate connected to the pull rod is separated from the first clamping groove, and then the laser ranging sensor body can be pushed out along the direction of the limiting groove notch, thereby making it convenient for staff to quickly disassemble and use the laser ranging sensor body at the high place of the bridge crane;

[0018] Third, in the present invention, the air guide block is inserted into the matching groove at one end of the air guide cover. During insertion, the matching groove notch squeezes the inclined surfaces of the second card-in ends of the two ends of the air guide block, so that the second movable plate connected to the second card block slides on the guide rod at the installation groove and compresses the second spring. When the air guide block is inserted into the matching groove, and the position of the second card block corresponds to the position of the second card slot, the second spring pushes the second card block connected to the second movable plate into the second card slot through resetting, so that the air guide block can be quickly disassembled and assembled on the air guide cover.
