Description

Technical Field

[0001] The utility model belongs to the technical field of PMIO large card insurance, and in particular relates to a PMIO large card insurance replacement tool. Background Art

[0002] Our company is a typical coking enterprise. The production control system uses 4 sets of American Honeywell C200 control systems. Due to the design problem of the cabinet, the operation of replacing the PMIO large card fuse has the characteristics of high fuse pin damage rate, long fuse replacement operation time, and high manpower maintenance cost.

[0003] like Figure 1 As shown, under each row of 15 PMIO large cards 5 in the PMIO cabinet, there is a 46cm*16.5cm empty slot cover. Both ends of the empty slot cover in the horizontal direction are fixed to the cabinet frame with buckles. Since there are no effective fulcrums around the empty slot cover, it is very difficult to open the cover.

[0004] After the empty slot cover is opened, the indoor lighting cannot shine into the cabinet because there is no lighting facility in the cabinet and is blocked by the upper row of PMIO large cards 5, causing the working space in the cabinet to be dark and unable to carry out fuse replacement operations.

[0005] The PMIO card's wiring board 1 is fixed on the cabinet backplane, which is about 29.5 cm deep. There are 19 cables about 25 square meters in front of the wiring board 1. When replacing the fuse, the maintenance personnel can only put one hand through the cable gap to carry out the operation, which is very easy to accidentally touch other cables and cause communication interruption accidents.

[0006] like Figure 2 As shown in the figure, the diameter of the cylindrical fuse cap 6 is 6mm and the height is 9mm. The diameter of the pin 7 below it is only 0.5mm. The distance between the two pins 7 is about 2.5mm. It is very difficult to accurately insert two such small pins 7 into the two small round holes of the fuse base. If the angle of holding the fuse is slightly deflected or the position of inserting the fuse is slightly offset from the base, it is very easy to cause the fuse pin to be damaged and cannot be used.

[0007] like Figure 1 As shown, the installation position of the fuse is between two cable heads with an interval of 1.5 cm. The fuse needs to be pinched from the top and bottom to insert into the base 2. However, in general, the thickness of fingers exceeds 1.5 cm, and the actual operation is difficult. Due to the space occupied by 19 cables and the installation position of the fuse, the operation of replacing the fuse is only allowed to be performed by maintenance personnel with thinner arms and fingers, which limits the number of operators.

[0008] Therefore, a PMIO large card insurance replacement tool is needed. Utility Model Content

[0009] The utility model aims to provide a PMIO large card insurance replacement tool.

[0010] The technical solution adopted by the utility model to solve its technical problems is: a PMIO large card fuse replacement tool, including cross-arranged and identically structured rod bodies, a handle ring is provided at the first end of the rod body, a battery and a switch for controlling an LED light are installed on the handle ring; an LED light is installed at the end of the second end of the rod body, and a 6mm deep groove is provided at the end of the second end to form a 1 / 4 circular structure.

[0011] Specifically, an elbow is installed at the tail of the handle ring to tilt up the empty slot cover plate.

[0012] Specifically, the cross-arranged rods with the same structure are fixed by pins.

[0013] Specifically, the distance from the end of the second end to the pin is 32 cm.

[0014] The utility model has the following beneficial effects: the fuse is installed through LED lighting, the tool has a simple principle and low maintenance cost, and replacing the fuse is more convenient, safe, time-saving and labor-saving, which greatly reduces the difficulty of replacing the fuse and the special requirements for operators. Its strong safety makes it more suitable for complex on-site working environments and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model will now be further described in detail with reference to the accompanying drawings.

[0020] like Figure 3As shown, a PMIO large card fuse replacement tool comprises a cross-arranged rod body 10 with the same structure, a handle ring 8 is provided at the first end of the rod body 10, the handle ring 8 is made of thick plastic with insulating properties, a layer of rubber pad is adhered to the surface, a battery cover 13 is left on the handle ring 8 for replacing button batteries, and a battery 11 and a switch 12 for controlling an LED light are installed on the handle ring 8; an LED light 14 is installed at the end of the second end of the rod body 10, which is convenient for quickly locating the position of the pin hole of the fuse base and realizing rapid replacement of the fuse; the second end of the rod body 10 is made of thick plastic with insulating properties, the second end of the rod body 10 is hollow, and is arranged with a power cord and an LED light 14, wherein the LED light 14 is placed at the end of the second end, and plays a lighting role when installing the fuse; a 6mm deep groove is provided at the end of the second end to form a 1 / 4 circular structure, and the groove is wrapped with a silicone sleeve, which is convenient for reducing pressure and preventing slipping while clamping the fuse, and preventing the difficulty of rotating the pin angle.

[0021] The tail of the ring 8 is provided with an elbow 15 for tilting the empty slot cover plate, saving time and effort.

[0022] The rod bodies 10 which are cross-arranged and have the same structure are fixed by the pin shaft 9 .

[0023] The distance from the end of the second end to the pin 9 is 32 cm, and after the rod body 10 is closed, the diameter of the groove is 3 mm.

[0024] The method of using the utility model is as follows: the user holds the handle ring 8, places the elbow 15 of the first end of the rod body 10 into the empty slot cover to open it, turns on the LED light 14 through the switch 12 after opening it, and then places the second end of the rod body 10 onto the safety cap to be replaced, squeezes the two rod bodies toward the middle, thereby clamping the safety cap, and thus removing the safety.
