Description

Technical Field

[0001] The utility model relates to an electrical control cabinet structure for marine engineering, in particular to an electrical control cabinet for a large-scale structural ship loading device that conforms to ergonomics. Background Art

[0002] Large-scale ship loading equipment is a commonly used device in marine engineering. It requires hydraulic operation, which means that the electrical control cabinet of the loading equipment generally integrates many circuits, electrical components, and various instrumentation facilities. The loading of large structures usually takes several days to complete. When operating the loading equipment, workers need to constantly check the electrical control cabinet to ensure the normal operation of the equipment. However, the electrical control cabinets of existing loading equipment are relatively large in size, and various instruments and detection devices are contained within the electrical control cabinets. This means that workers need to carry escalators themselves to check the instruments in the electrical control cabinets, which is very inconvenient. In addition, when large-scale ship loading is carried out at night, the numbers on the instruments in the electrical control cabinets are small and the lighting conditions are poor, making them difficult to see clearly. Workers need to carry flashlights and open the electrical control cabinets to operate. At the same time, if the large-scale ship loading equipment needs to be repaired, the open cabinet door has no fixed structure, which will also cause certain inconveniences to the maintenance workers.

[0012] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] As shown in the accompanying drawings, an electrical control cabinet for large-structure ship loading equipment comprises a cabinet body 1, comprising a front-opening housing 1-7. A cabinet door 1-2 is pivotally connected to a side frame of the open portion of the housing 1-7 via a hinge 1-1. A pressure switch 1-8 is installed at the point where the cabinet door meets the housing 1-7. This pressure switch 1-8 is connected via a wire to a first control switch for a first light 1-11 installed within the housing 1-7. A second light 1-9 is secured to the upper inner wall of the cabinet door 1-2. One to three second lights are provided. A glass window 1-6 is provided in the cabinet door 1-2, with explosion-proof observation glass mounted above the window. A handle 1-14 and a second control switch 1-13 connected via a wire to the second light 1-9 are mounted on the outer wall of the cabinet door 1-2. A circular hole 1-12 is provided in the bottom of the housing 1-7 for passing the connecting wires of the instruments within the control cabinet.

[0014] Preferably, a first support column 1-5 is installed on the bottom wall inside the box body 1-7 and close to the opening of the box body, a first cylindrical support block is arranged on the first support column 1-5, a first hinge support 1-3 is fixed on the inner side of the inner wall of the cabinet door 1-2, a second support column 1-10 is fixed at a position corresponding to the horizontal level of the hinge 1-3, a second cylindrical support block is arranged on the second support column 1-10, one end of the connecting rod 1-4 is rotatably connected to the first hinge support 1-3, and the other end of the connecting rod 1-4 has a through hole. When the cabinet door 1-2 is closed, the through hole of the connecting rod 1-4 is nested in the second cylindrical support block, and when the cabinet door 1-2 is opened, the through hole of the connecting rod 1-4 is nested in the first cylindrical support block, thereby fixing the cabinet door 1-2.

[0015] The escalator structure 2 includes a carrying box aligned with the opening direction of the box body. The cabinet body 1 is fixed to the upper portion of the carrying box's top surface via columns 3. A carrying frame 2-1 is fixed within the carrying box. Two second hinge supports 2-3 are mounted on the inner wall of the upper top plate of the carrying frame 2-1 and on the side wall of the carrying frame opposite the opening side of the carrying box, respectively, at intervals on the left and right. The second hinge support 2-3 on the upper top plate is hingedly connected to one end of a second connecting rod 2-4, the other end of which is hingedly connected to a folding escalator plate 2-5. The folding escalator plate 2-5 utilizes an existing retractable folding escalator structure. The second hinge support 2-3 connected to the side wall of the carrying frame is fixedly connected to the base of a pneumatic push-pull rod 2-2, the push rod end of the pneumatic push-pull rod 2-2 being hingedly connected to the folding escalator plate 2-5. The folding escalator plate can be extended out of the opening of the carrying box or retracted into the carrying box under the action of the pneumatic push-pull rod 2-2 and the second connecting rod 2-4.

[0016] The working principle of this system is as follows:

[0017] When the large-scale structure loading device is in normal use and the electrical control cabinet is operating normally, the maintenance personnel will pull out the folding escalator plate 2-5 of the escalator structure 2 during the inspection. The maintenance personnel can clearly observe the instrument data of the control cabinet through the glass window 1-6 by stepping on the folding escalator plate 2-5. If the lighting conditions are poor, the staff can turn on the second control switch 1-13 and the second lighting lamp 1-9. Under the illumination of the second lighting lamp 1-9, the instrument data of the control cabinet can be clearly observed; when When the instruments in the control cabinet need to be inspected, the maintenance personnel step on the folding escalator plate 2-5 and open the cabinet door 1-2 through the handle 1-14. When the cabinet door 1-2 is opened, the pressure switch 1-8 is triggered, and the pressure switch 1-8 is connected to the first lighting lamp 1-11 through the wire. The first lighting lamp 1-11 illuminates the inside of the cabinet body 1-7. At the same time, the inspection personnel remove the connecting rod 1-4 placed on the second support column 1-10, and place the through hole on the connecting rod 1-4 on the first support column 1-5 to fix the cabinet door 1-2, which is convenient for the inspection personnel.
