Description
Technical Field
[0001] This utility model belongs to the field of crane conductor rail maintenance technology, and particularly relates to a metallurgical crane conductor rail maintenance device. Background Technology
[0002] Metallurgical cranes are a type of crane that operates by longitudinal movement along factory rails, lateral movement of the trolley, and lifting / lowering of the hook. They are suitable for metal smelting workshops and are specialized cranes used for lifting molten metal. Metallurgical cranes typically use three-phase AC power. The sliding contact line, also known as the conductor rail, is a power transmission device that supplies power to the moving equipment. Therefore, metallurgical cranes in smelting workshops also use sliding contact lines to supply power. However, due to the presence of dust particles in smelting workshops, these particles accumulate on the sliding contact line over time. This accumulation can lead to poor contact between the conductive slider and the energized rail, resulting in poor power supply to the metallurgical crane and affecting metallurgical production. Therefore, timely cleaning of the dust on the sliding contact line is necessary. Currently, workers typically turn off the power and climb onto the steel structure of the factory to clean the sliding contact line, which is inefficient and poses a risk of fall for workers operating at height. Cleaning the sliding contact line is also very inconvenient. Utility Model Content
[0003] To address the technical problems of inconvenient and inefficient cleaning of existing metallurgical crane sliding contact lines, this utility model provides a metallurgical crane sliding contact line maintenance device, including two parallel and spaced-apart end beams, and two parallel and spaced-apart adjustable main beams between the two end beams. Both the main beams and the end beams serve a supporting function. The two ends of the main beams are detachably fixed to the end beams, and both ends of the end beams are equipped with running mechanisms. The left end beam of the main beam includes two symmetrically arranged support beams, each equipped with a running mechanism at both ends. The two support beams are aligned along the same center line, and a connecting beam connects them. The two ends of the connecting beam are hinged to the support beams via pins. This design prevents the traveling wheels of the running mechanism from becoming suspended in the air. When the travel track is uneven, since the main beam and end beams are fixed together, forming a crane frame, the large size of the crane frame means that the traveling wheels could become suspended in the air, potentially causing deformation of the main beam or end beam and severely impacting the crane's lifespan. By hinged to the support beams and connecting beams on the left end beam, the suspension of the traveling wheels is prevented when the travel track is uneven. The main beam consists of two horizontally arranged standard sections. Several variable sections are detachably connected between the two standard sections via connecting plates. The number of variable sections can be selected according to requirements. All variable sections are fixed together by connecting plates. Lifting lugs are located at the top of each variable section. Several parallel and spaced support rods are installed between the variable sections, with both ends detachably fixed to the variable sections. The lifting lugs facilitate lifting the device onto the traveling track on the steel structure workshop. The running mechanism includes traveling wheels, a reducer, and a traveling motor. The traveling wheels are rotatably mounted on the end beams. The reducer and traveling motor are detachably fixed to the end beams via support frames. The traveling motor is connected to the traveling wheels via the reducer. The traveling motor is connected to the power supply and the PLC controller in the electrical control cabinet via cables. Starting the traveling motor causes the traveling wheels to move longitudinally along the traveling track on the steel structure workshop, thereby moving the device along the length of the sliding contact line. This allows operators to adjust the position of the cage as needed. One of the main beams has a platform fixed to its outer side, which serves as a support. The platform is equipped with an electrical control cabinet and a power supply unit. The electrical control cabinet contains electrical components such as a PLC, and all electrical components in the cabinet are connected to the power supply unit via cables. The inner sides of both main beams are equipped with two vertically arranged upper hanging rods. The top of the upper hanging rods is detachably fixed to the main beams via a fixing seat. Below the main beams is a horizontally arranged cage for maintenance. The cage is fixed with four lower hanging rods that correspond one-to-one with the upper hanging rods. The upper and lower hanging rods are detachably fixed and connected via flanges.
[0004] Preferably, the top of the main beam is provided with a main beam railing for protection.
[0005] Preferably, the platform is equipped with a protective railing.
[0006] Preferably, both ends of the end beam are provided with buffers that serve as a buffer.
[0007] Preferably, the power supply component is a DC battery, and the walking motor is a DC motor.
[0008] Preferably, the length of the cage is longer than the length of the end beam, which facilitates multiple people to clean the conductor rail simultaneously and improves cleaning efficiency.
[0009] The above scheme has the following advantages: One of the end beams is designed with a hinged connection between the support and the connecting beam. This design prevents the traveling wheels of the running mechanism from being suspended in the air, avoids deformation of the main beam or end beam, and also reduces the impact on the service life of the crane. The main beam is made of an adjustable length to meet the needs of factory workshops with different spans, saving production costs and improving adaptability. The length of the cage is longer than the length of the end beam, which facilitates multiple people to clean the conductor rail simultaneously, thus improving cleaning efficiency. The running mechanism allows the device to move along the length of the conductor rail. After the dust on the conductor rail next to the cage has been cleaned, the device can be moved to an area of the conductor rail that has not been cleaned, facilitating the movement of the cage.

Detailed Implementation
[0012] like Figure 1-4As shown, a maintenance device for the sliding contact line of a metallurgical crane includes two parallel and spaced-apart end beams 2. Between the two end beams 2, there are two parallel and spaced-apart adjustable main beams 1. Both the main beams 1 and the end beams 2 serve as supports. The two ends of the main beams 1 are detachably fixed to the end beams 2. Both ends of the end beams 2 are provided with running mechanisms 3. The left end beam 2 of the main beam 1 includes two symmetrically arranged support beams 21, and both ends of the support beams 21 are equipped with running mechanisms 3. The two support beams 21 are arranged along the same center line, and a connecting beam 22 is provided between the two support beams 21. The two ends of the connecting beam 22 are hinged to the support beams 21 by pins. This arrangement can prevent the traveling wheels 31 of the running mechanism 3 from being suspended in the air. When the traveling track 6 is uneven, since the main beam 1 and the end beam 2 are fixed together to form a crane beam frame, and the crane beam frame is large, the traveling wheels 31 will be suspended in the air when the traveling track 6 is uneven, which may even cause the main beam 1 or the end beam 2 to deform, seriously affecting the service life of the crane. Since the left end beam 2 of the main beam 1 is set in a way that is hinged to the support beams 21 and the connecting beam 22, the phenomenon of the traveling wheels 31 being suspended in the air will be avoided when the traveling track 6 is uneven. The main beam 1 includes two horizontally arranged standard main beam sections 11. Several variable main beam sections 12 are detachably connected between the two standard main beam sections 11 via connecting plates 18. The number of variable main beam sections 12 can be selected according to requirements. The variable main beam sections 12 are fixed together by connecting plates 18. The top of the variable main beam section 12 is provided with lifting lugs 14. Several parallel and spaced support rods 13 are provided between the variable main beam sections 12. The two ends of the support rods 13 are detachably fixed to the variable main beam section 12. The setting of support rods 13 can enhance stability. The setting of lifting lugs 14 makes it convenient to lift the device onto the traveling track 6 on the steel structure workshop. The operating mechanism 3 includes a traveling wheel 31, a reducer 32, and a traveling motor 33. The traveling wheel 31 is rotatably mounted on the end beam 2. The reducer 32 and the traveling motor 33 are detachably fixed on the end beam 2 through a support frame. The traveling motor 33 is connected to the traveling wheel 31 through the reducer 32. The traveling motor 33 is connected to the power supply component 152 and the PLC controller in the electrical control cabinet 151 through a cable. When the traveling motor 33 is started, it drives the traveling wheel 31 to move longitudinally along the traveling track 6 on the steel structure workshop, thereby enabling the device to move along the length of the sliding contact line 7, which allows the staff to adjust the position of the cage 4 as needed.One of the main beams 1 has a platform 15 fixed to its outer side, which serves as a support. The platform 15 is equipped with an electrical control cabinet 151 and a power supply component 152. The electrical control cabinet 151 contains electrical components such as a PLC, and all electrical components in the electrical control cabinet 151 are connected to the power supply component 152 via cables. The inner sides of both main beams 1 are equipped with two vertically arranged upper hanging rods 41. The top of the upper hanging rods 41 is detachably fixed to the main beam 1 via a fixing seat 42. The lower part of the main beam 1 is equipped with a horizontally arranged cage 4 for maintenance. The cage 4 is fixed with four lower hanging rods 43 that correspond one-to-one with the upper hanging rods 41. The upper hanging rods 41 and the lower hanging rods 43 are detachably fixedly connected via flanges 44.
[0013] Preferably, the top of the main beam 1 is provided with a main beam railing 16 for protection.
[0014] Preferably, the platform 15 is provided with a platform railing 17 for protection.
[0015] Preferably, the two ends of the end beam 2 are provided with buffers 23 that serve as buffers.
[0016] Preferably, the power supply component 152 is a DC battery, and the walking motor 33 is a DC motor.
[0017] Preferably, the length of the cage 4 is longer than the length of the end beam 2, which facilitates multiple people to clean the conductor rail 7 at the same time and can improve cleaning efficiency.
[0018] Usage process: In use, the metallurgical crane in the factory workshop is first moved to one end of the workshop and the power supply to the sliding contact line 7 is disconnected. Then, the device is installed on the traveling track 6 on the steel structure beam 5 of the factory workshop by hoisting. Workers carry maintenance and cleaning tools into the cage 4 and clean the dust off the sliding contact line 7. After the sliding contact line 7 next to the cage 4 is cleaned, the traveling motor 33 is started. The traveling motor 33 drives the traveling wheel 31 to rotate. The traveling wheel 31 moves along the traveling track 6 and moves the cage 4 to the bottom of the uncleaned sliding contact line 7. The workers continue to clean the sliding contact line 7. After cleaning, the traveling motor 33 is started again to move the device forward until the sliding contact line 7 is cleaned.
