Description

Technical Field

[0001] The present invention relates to the field of electric power detection equipment, and in particular to a calibration device fully compatible with electric energy meters and terminal calibration. Background Art

[0002] The automated verification line is a device suitable for the verification and testing of large-scale electric energy metering instruments. Traditional automated verification lines generally adopt "professional construction", that is, one line can only verify / test one type of equipment. For example, the automatic verification line of single-phase electric energy meters can only carry out single-phase electric energy meter tests. In recent years, with the in-depth promotion of macro policies such as the market-oriented reform of electricity and the optimization of the business environment, the technical and management requirements of power companies for electric energy metering and collection have been continuously improved, and the demand for electric energy metering instruments at the terminal has changed significantly. On the one hand, the "professional construction" design idea of ​​the traditional assembly line is difficult to adapt to the phenomenon of uneven distribution of terminal meter demand in each month of the year. The verification and testing task volume of the assembly line varies greatly throughout the year, the utilization rate is extremely low during the trough period, and it is difficult to complete the verification and testing production tasks during the peak period; on the other hand, with the in-depth promotion of the construction of the new generation of electric power intelligent measurement system, various new types of metering and collection equipment have emerged rapidly. Under the existing technical scheme, each new type of metering equipment needs to continuously purchase automated assembly lines to meet its verification and testing needs, which not only occupies the site but also increases the cost of equipment purchase.

[0003] Therefore, in recent years, the call for improving the "compatibility" of the calibration line has gradually emerged, and compatible calibration lines with certain compatibility have emerged: the crimping mechanisms of different equipment are fixed at different heights, and the equipment to be tested is lifted to different heights to achieve calibration and testing of different types of equipment to be tested. However, this solution still has the following problems: First, the lifting height of the equipment to be tested is limited, and as the lifting height increases, the stability of the equipment to be tested decreases, and the reliability of the wiring decreases. Therefore, the number of compatible equipment on the line is limited, and the utilization rate of the upper equipment is not high. Second, different crimping mechanisms and electrical measuring equipment use fixed wiring methods, and it is difficult to replace the crimping mechanism. The compatible transformation of new equipment still requires a large amount of time and financial costs. Summary of the invention

[0027] In order to achieve the compatible placement of electric energy meters 20 of different specifications and types, the fully compatible meter tray 19 is provided with a plurality of placement interfaces of electric energy meters 20 to fully and compatibly set electric energy meters 20 of different specifications and types.

[0028] In order to realize the lifting and lowering drive of the multi-layer table stand lifting platform 2, as Figure 4 As shown, the lifting transmission assembly 8 includes a coupling 801 and a ball screw, the coupling 801 is connected between the output shaft of the lifting drive motor 7 and the upper end of the ball screw shaft 802, the upper and lower ends of the ball screw shaft 802 are rotatably connected to the screw shaft seat 803, the screw shaft seat 803 is connected and fixed to the side bracket plate 1, and the ball nut 804 of the ball screw is connected and fixed to the side of the multi-layer table stand lifting platform 2 through the connecting seat 805. The vertical transmission structure of the lifting transmission assembly 8 is effectively realized, and the lifting drive of the multi-layer table stand lifting platform 2 is realized.

[0029] In order to support more types of connection and disconnection operations of the electric energy meter 20, such as Figure 5 As shown, the lifting platform side plate 202 includes a support plate 20201 and a transition plate 20202, and the transition plate 20202 is detachably connected between two adjacent upper and lower support plates 20201 by bolts. The detachable structure supports the vertical expansion of the multi-layer meter stand lifting platform 2, and the number of layers of the multi-layer meter stand lifting platform 2 can be expanded according to actual production needs. It has good scalability and can support the connection and disconnection operations of more types of electric energy meters 20.

[0030] In order to realize the horizontal and vertical mobile support structures, such as Figure 6 As shown, the support plate 20201 includes a vertical side plate portion 202011 and a horizontal support plate portion 202012, and the horizontal support plate portion 202012 is arranged on the inner side of the vertical side plate portion 202011, as shown in FIG. Figure 3 As shown, each layer of the table base mounting plate 201 is correspondingly connected to the horizontal support plate portion 202012 of the corresponding support plate 20201 through the horizontal slide rail moving assembly 4, the horizontal slide rail moving assembly 4 includes a horizontal linear guide rail 401 and a matching horizontal slide groove block 402, the upper end of the horizontal slide groove block 402 is detachably connected and fixed to the bottom surface of the table base mounting plate 201, and the horizontal linear guide rail 401 is detachably connected and fixed to the horizontal support plate portion 202012; a connecting block 303 is provided on the outer side of the lower part of the vertical side plate portion 202011, and a vertical slide rail moving assembly 3 is connected to the outer side of the connecting block 303, the vertical slide rail moving assembly 3 includes a vertical linear guide rail 301 and a matching vertical slide groove block 302, the vertical slide groove block 302 and the connecting block 303 are detachably connected and fixed, and the vertical linear guide rail 301 is detachably connected and fixed to the side support plate 1. This structure can effectively realize the horizontal movable support structure and the vertical movable support structure for each layer of the table base mounting plate 201.

[0031] In order to prevent the table base mounting plate 201 from sliding randomly, Figure 5As shown, an electromagnetic lock 9 is provided on the vertical side plate 202011 at a height position corresponding to each layer of the table base mounting plate 201, and a lock hole is provided on the side of the table base mounting plate 201 corresponding to the position of the lock head of the electromagnetic lock 9. The electromagnetic lock 9 is used to lock each layer of the table base mounting plate 201 to prevent each layer of the table base mounting plate 201 from sliding when the multi-layer table base lifting platform 2 moves vertically. When the table base mounting plate 201 moves vertically to the connection and disconnection working position, the lock head of the electromagnetic lock 9 withdraws from the lock hole on the side of the table base mounting plate 201, and can move horizontally under the drive of the crimping cylinder 5.

[0032] In order to make the table base mounting plate 201 move vertically and accurately to the connection and disconnection working position and perform travel limit, Figure 4 As shown, a positioning photoelectric sensor 11 is provided on the side bracket plate 1 at a height position corresponding to the connection and disconnection work of the electric energy meter 20. The positioning photoelectric sensor 11 is arranged on one side of one of the vertical linear guide rails 301, and each connecting block 303 of the vertical slide rail moving assembly 3 to which the vertical linear guide rail 301 belongs is connected with a sensing sheet 12. The positioning photoelectric sensor 11 is used for positioning when the meter base mounting plate 201 is vertically moved to the connection and disconnection work position. When the meter base mounting plate 201 is vertically moved to the connection and disconnection work position, the lifting drive motor 7 stops driving. A limit photoelectric sensor 13 is provided at the upper and lower ends of the vertical slide rail moving assembly 3 on the side bracket plate 1. The limit photoelectric sensor 13 above the positioning photoelectric sensor 11 is lower than the upper end of the vertical slide rail moving assembly 3, and the limit photoelectric sensor 13 below the positioning photoelectric sensor 11 is higher than the lower end of the vertical slide rail moving assembly 3. The positioning photoelectric sensor 11 and the limit photoelectric sensor 13 are both provided with a vertically penetrating induction groove. When the multi-layer table base lifting platform 2 is used, the induction sheet 12 can move vertically through the induction groove. It is convenient to realize mobile positioning and limiting. When the table base mounting plate 201 moves vertically to the wiring connection and removal working position, the lifting drive motor 7 stops driving and realizes the travel limit at the upper and lower ends.

[0033] In order to better prevent the multi-layer table stand lifting platform 2 from moving vertically beyond the stroke, as Figure 4 As shown, the side bracket plate 1 is provided with limit blocks 14 at the upper and lower ends of the vertical slide rail moving assembly 3, the lower end surface of the upper limit block 14 is higher than the upper limit photoelectric sensor 13, and the lower end surface of the upper limit block 14 is lower than or equal to the upper end surface of the vertical slide rail moving assembly 3; the upper end surface of the lower limit block 14 is lower than the lower limit photoelectric sensor 13, and the upper end surface of the lower limit block 14 is higher than or equal to the lower end surface of the vertical slide rail moving assembly 3. By setting the limit blocks 14, the vertical movement limit of the multi-layer table stand lifting platform 2 can be better realized, and when the limit photoelectric sensor 13 fails, the extreme limit protection is realized.

[0034] In order to realize the front and rear movement drive of the table base mounting plate 201, as Figure 7 As shown, the head of the driving rod of the crimping cylinder 5 is provided with a circumferential flange 501, and each table base mounting plate 201 is provided with a limiting groove 20101 with an anti-slip groove neck corresponding to the circumferential flange 501. When the multi-layer table base lifting platform 2 is used, the circumferential flange 501 can relatively pass through the limiting groove 20101. After the table base mounting plate 201 is vertically moved to the wire connection and disconnection working position, when the driving rod of the crimping cylinder 5 moves horizontally in the front-back direction, the limiting groove 20101 of the table base mounting plate 201 can be offset against the head of the driving rod of the crimping cylinder 5 in the front-back direction to drive the table base mounting plate 201 to move in the front-back direction.

[0035] In this embodiment, the temporary fixing device 21 for connecting and disconnecting stitches is driven by a cylinder.

[0036] In this embodiment, the lifting drive motor 7 is a servo motor, which is arranged on the side support plate 1 on one side of the lifting movement mechanism.

[0037] In this example, a frame table is provided at the lower portion of the equipment frame 15, the electrical measuring device 17 is provided in the rear area of ​​the frame table, and the controller 18 is connected and fixed to the front upper corner of the equipment frame 15. Depending on the convenience of the actual assembly line operation, the electrical measuring device 17 and the controller 18 may not be provided on the calibration equipment.

[0038] The calibration equipment is installed on the calibration production line of the electric energy meter 20. In this example, the connection and disconnection of the three-phase electric energy meter is calibrated as an example. The three-phase electric energy meter is placed on the fully compatible meter tray 19, and the upper layer of the multi-layer meter seat lifting platform 2 is provided with a corresponding meter connection and disconnection seat 203 of the three-phase electric energy meter. When working, the fully compatible meter tray 19 moves on the double-speed belt conveyor line 16. After the double-speed belt conveyor line 16 carries the three-phase electric energy meter to the preset connection and disconnection working position of the calibration equipment, the double-speed belt conveyor line 16 stops, and the lifting drive motor 7 in the automatic connection and disconnection mechanism is started, so that the multi-layer meter seat lifting platform 2 is lowered, and the meter connection and disconnection seat 2 provided with the three-phase electric energy meter is provided. The upper meter seat mounting plate 201 of 03 moves downward to the connection and removal working position, which is achieved by positioning the photoelectric sensor 11, and then the cylinder in the connection and removal temporary fixing device 21 is actuated to temporarily fix the three-phase electric energy meter from the upper and lower sides. Subsequently, the controller 18 controls the electromagnetic lock 9 to unlock, and the crimping cylinder 5 is actuated to push the upper meter seat mounting plate 201 to move toward the fully compatible meter tray 19, so that the meter connection and removal seat 203 completes the crimping of the three-phase electric energy meter. After the crimping is completed, the electric measuring equipment 17 performs the calibration operation on the three-phase electric energy meter. After the calibration operation is completed, the crimping cylinder 5 performs the exit action to complete the removal of the wires. The double-speed belt conveyor line 16 is started to transport the fully compatible meter tray 19 to the next process.

[0039] Since there are many types of electric energy meters 20 or collection terminals to be calibrated, the meter connection and disconnection sockets 203 of different electric energy meters 20 and collection terminals can be respectively arranged on different layers of the multi-layer meter socket lifting platform 2. Since the fully compatible meter tray 19 can also hold different types of electric energy meters 20 and collection terminals, under the control of the controller 18, the same calibration equipment can be fully compatible with different electric energy meters 20 and collection terminal connection and disconnection operations and calibrations, so that one calibration line can be fully compatible with the calibration of various electric energy meters 20, thereby reducing the calibration cost.

[0040] above Figure 1-7 The calibration equipment for a fully compatible electric energy meter and terminal calibration shown is a specific embodiment of the present invention, which has embodied the outstanding substantial features and progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
