Description

Technical Field

[0001] The invention belongs to the technical field of electric energy meter calibration and conveying equipment, and in particular relates to a flexible calibration and conveying unit for a variable gauge electric energy meter. Background Art

[0002] During the production process, the energy meter is verified (i.e., the meter is tested and calibrated) to ensure its accuracy and reliability. The energy meter is an important device used to measure the energy consumption in the power system. Its accuracy directly affects the fairness of electricity billing and the vital interests of users. Therefore, the verification of the energy meter is very important to ensure fair transactions in the power market and avoid disputes and losses caused by measurement errors.

[0003] During the calibration process of the electric energy meter, the electric energy meter is transported by a pair of parallel belt lines. Due to the limitation of the size of the electric energy meter, the distance between the pair of belt lines is also limited, and it is impossible to meet the transportation of different types of meters using one conveyor line. As a result, the larger three-phase electric energy meter or collection terminal / concentrator and the smaller single-phase electric energy meter need to be transported by different belt lines, which is prone to problems such as asset waste, inventory space waste, and low adjustment and conversion efficiency.

[0004] In addition, in order to ensure the stability of the electric energy meter in the conveying of the belt line, so that the electric energy meter can be aligned with the calibration device when being conveyed to the calibration device for calibration, the electric energy meter is usually straightened manually or by a corresponding push plate; however, when the push plate pushes the electric energy meter to straighten it, it is easy to cause the belt line to deform in the vertical direction along the conveying direction of the belt line. When the belt line is reset under the action of its own elasticity, it is easy to cause the electric energy meter to deflect again, affecting the conveying effect of the electric energy meter.

DETAILED DESCRIPTION

[0020] A flexible calibration and transmission unit for variable gauge electric energy meters, such as Figure 1-10As shown, it includes a support frame, a fixed belt line 4 is provided on the support frame, an adjusting belt line 6 arranged parallel to the fixed belt line 4 is slidably connected to the support frame, and a straightening device 5 for straightening the electric energy meter transported on the fixed belt line 4 and the adjusting belt line 6 is provided on the support frame; the straightening device 5 includes a straightening box 12 slidably connected to the support frame and moving in a vertical direction along the conveying direction of the fixed belt line 4, the straightening box 12 is provided with a pushing component for pushing the electric meter, and a baffle 7 corresponding to the pushing component is fixedly connected to the adjusting belt line 6; a pair of clamping blocks 21 with opposite movement directions and arranged on both sides of the straightening component are slidably connected to the straightening box 12, and a driving structure is provided on the pair of clamping blocks 21, and the output end of the driving structure is connected to the clamping plate 14, and the driving structure can drive the clamping plate 14 to move forward and backward while moving horizontally to straighten the electric energy meter, and then move horizontally with the horizontal movement of the clamping plate to clamp the electric energy meter.

[0021] When the present invention is in use, when the inspection unit transports a large-sized three-phase electric energy meter or a collection terminal / concentrator, the adjusting belt line 6 is slid along the support frame to increase the distance between the adjusting belt line 6 and the fixed belt line 4, so that the present application becomes a wide-track state; when the transport object is a small-sized single-phase electric energy meter, the distance between the adjusting belt line 6 and the fixed belt line 4 is reduced to change the present application into a narrow-track state, so that the present application can transport electric energy meters or collection terminals / concentrators of different sizes, thereby improving the compatibility of the present application.

[0022] When the belt line 6 and the fixed belt line 4 are adjusted to transport the electric energy meter, the electric energy meter is straightened by the straightening device 5, which can effectively avoid the electric energy meter from being skewed during transportation, so that the electric energy meter transported to the calibration device can be aligned with the calibration device, so as to facilitate the calibration device to calibrate the electric energy meter and improve the accuracy of the calibration of the electric energy meter.

[0023] Specifically, when the straightening device 5 straightens the electric energy meter, it first slides the straightening box 12 along the support frame, so that the straightening box 12 pushes the electric energy meter through the pushing component to perform the initial straightening and resetting; after the pushing component straightens and resets the electric energy meter for the initial straightening and resetting, the straightening box 12 drives the pushing component to retreat to limit the electric energy meter; a pair of clamping blocks 21 drives the driving structure to act, and the driving structure drives the clamping plate 14 to move, and the driving structure drives the clamping plate 14 to move back and forth while moving horizontally to straighten the electric energy meter. In the straightening process, the electric energy meter is reset under the force of the back and forth movement of the clamping plate 14 and the force of the belt line's own reset; that is, in the process of the belt line driving the electric energy meter to reset, the belt line is assisted in resetting the electric energy meter by the back and forth movement of the clamping plate 14; finally, the straightening box 12 pushes the electric energy meter through the pushing component for final straightening, and the secondary straightening and resetting can effectively alleviate the problem of the electric energy meter being skewed due to the deformation of the belt line.

[0024] Further, the support frame includes a support box 1, and support feet 2 are provided on the support box 1; a top plate 3 is fixedly connected to the top of the support box 1, a fixed belt line 4 is fixedly connected to the top plate 3, and an adjustable belt line 6 is slidably connected to the top plate 3.

[0025] Further, to enable the adjustable belt line 6 to slide along the top plate 3, as Figure 2 shown, an adjustable telescopic rod 9 is fixedly connected to the top plate 3, and the telescopic end of the adjustable telescopic rod 9 is fixedly connected to the adjustable belt line 6; a slider is fixedly connected to the adjustable belt line 6, and a slide rail 8 for guiding the slider is fixedly connected to the top plate 3; the adjustable belt line 6 is driven to move by the adjustable telescopic rod 9, and the movement of the adjustable belt line 6 is guided by the cooperation of the slider and the slide rail 8 to improve the stability of the adjustable belt line 6.

[0026] Further, to enable the alignment box 12 to slide along the support frame, as Figure 3 shown, an alignment telescopic rod 10 is fixedly connected to the support frame, and the telescopic end of the alignment telescopic rod 10 is fixedly connected to the alignment box 12; a pair of guide rods 11 are fixedly connected to the alignment box 12, and both of the pair of guide rods 11 are slidably connected to the support frame; the alignment box 12 is driven to slide along the support frame by the alignment telescopic rod 10, and the movement of the alignment box 12 is guided by the guide rods 11 to improve the stability of the alignment box 12.

[0027] Further, to enable the pair of clamping blocks 21 to move synchronously, as Figure 4 shown, the driving structure includes a clamping motor 16 fixedly connected to the alignment box 12, the output end of the clamping motor 16 is fixedly connected to a clamping double crank 17, and the central position of the clamping double crank 17 is fixedly connected to the output end of the clamping motor 16; both ends of the clamping double crank 17 are rotatably connected to clamping rods 19, and the pair of clamping rods 19 are respectively rotatably connected to the pair of clamping blocks 21; the clamping double crank 17 is driven to rotate by the clamping motor 16, and the clamping double crank 17 drives the clamping blocks 21 to slide along the alignment box 12 through the clamping rods 19.

[0028] Further, to enable the clamping plate 14 to move forward and backward while moving horizontally, as Figure 6 and Figure 7As shown, a pair of driving rods 29 are rotatably connected to the clamping block 21, and a synchronizing rod 32 is fixedly connected to the pair of driving rods 29; a driven rod 31 parallel to the driving rod 29 is also rotatably connected to the clamping block 21, a parallel rod 30 is rotatably connected to the driven rod 31, the other end of the parallel rod 30 is rotatably connected to the driving rod 29, and the end of the parallel rod 30 close to the driving rod 29 is perpendicularly and fixedly connected to the middle of the clamping plate 14; a rotating frame 26 is rotatably connected to the clamping block 21, a connecting rod 27 is rotatably connected to the rotating frame 26, and a rocker 28 is fixedly connected to each of the pair of driving rods 29, and the connecting rod 27 is rotatably connected to one of the rockers 28.

[0029] Since the rotating frame 26, the connecting rod 27, and the rocker 28 form a crank-rocker mechanism, when the rotating frame 26 rotates, the rotating frame 26 drives the rocker 28 to rotate within a certain angle range through the connecting rod 27, and the rocker 28 drives the driving rod 29 to rotate; since the driving rod 29, the driven rod 31, and the parallel rod 30 form a parallelogram mechanism, when the driving rod 29 rotates, the driving rod 29 drives the parallel rod 30 to move back and forth while moving horizontally through the driven rod 31, and the parallel rod 30 drives the clamping plate 14 to move back and forth while moving horizontally.

[0030] Further, as shown in Figure 4 、 5 8, 9, a pair of connection blocks 22 corresponding to the pair of clamping blocks 21 are slidably connected in the alignment box 12, and a separating plate 36 is fixedly connected to each of the pair of connection blocks 22; a driving rack 25 is fixedly connected to the separating plate 36, and a driving wheel 37 meshing with the driving rack 25 is coaxially fixedly connected to the rotating frame 26; an adjusting frame 20 is also fixedly connected to the connection block 22, and an activity groove 35 corresponding to the driving rack 25 is provided on the adjusting frame 20; a vertical groove 33 corresponding to the separating plate 36 is also provided on the adjusting frame 20, a roller 38 corresponding to the vertical groove 33 is rotatably connected to the other rocker 28, and a rotating slope 34 communicating the vertical groove 33 and the activity groove 35 is provided on the adjusting frame 20.

[0031] Before the clamping block 21 slides along the alignment box 12, the driving rack 25 and the adjusting frame 20 on the connecting block 22 are first adjusted so that the clamping plate 14 can be flush with the driving rod 29 at different positions, and the driving rod 29 and the clamping plate 14 cooperate to clamp and fix the electric energy meter, so as to improve the stability of clamping and fixing the electric energy meter in this application; specifically, first, the clamping block 21 drives the driving wheel 37 to move along the driving rack 25. Under the action of the driving rack 25, the driving wheel 37 rotates, and the driving wheel 37 drives the rotating frame 26 to rotate. At this time, the roller 38 on the rocker 28 is located in the movable groove 35; when the driving wheel 37 moves with the clamping block 21 to the separation plate 36, the roller 38 on the rocker 28 moves to the rotating slope 34, and the rocker 28 is driven to rotate under the action of the rotating slope 34 and the roller 38. The rocker 28 drives the driving rod 29 to rotate to a state where it is vertical and flush with the clamping plate 14, and the clamping block 21 continues to move, so that the driving rod 29 and the clamping plate 14 cooperate to fix the electric energy meter.

[0032] Further, to make the pair of connecting blocks 22 move synchronously, an adjusting motor 18 is fixedly connected to the alignment box 12, and an adjusting double crank 23 is fixedly connected to the output end of the adjusting motor 18. The central position of the adjusting double crank 23 is fixedly connected to the output end of the adjusting motor 18; both ends of the adjusting double crank 23 are rotatably connected to adjusting rods 24, and the pair of adjusting rods 24 are respectively rotatably connected to the corresponding connecting blocks 22. The adjusting motor 18 drives the adjusting rods 24 to rotate through the adjusting double crank 23, and the adjusting rods 24 drive the connecting blocks 22 to slide along the alignment box 12.

[0033] Further, as Figure 3 shown, the pushing assembly includes a pushing frame fixedly connected to the alignment box 12. A plurality of rotating rollers 13 are rotatably connected to the pushing frame, and anti-slip pads 15 corresponding to the plurality of rotating rollers 13 are fixedly connected to each of the pair of clamping plates 14; when the clamping plates 14 drive the electric energy meter to move horizontally and forward and backward at the same time through the anti-slip pads 15, the forward and backward movement of the electric energy meter is limited by the plurality of rotating rollers 13, and the horizontal movement of the electric energy meter is guided by the rotation of the rotating rollers 13, so as to improve the stability of the movement of the electric energy meter.

[0034] The working process of the present invention is as follows: When in use, when the object conveyed by the verification unit is a large-size three-phase electric energy meter or a collection terminal / concentrator, the adjusting telescopic rod 9 is adjusted to drive the adjusting belt line 6 to slide along the support frame, increasing the distance between the adjusting belt line 6 and the fixed belt line 4, so that this application becomes a wide-track state; when the conveyed object is a small-size single-phase electric energy meter, the distance between the adjusting belt line 6 and the fixed belt line 4 is reduced by adjusting the telescopic rod 9, so that this application becomes a narrow-track state, enabling this application to convey electric energy meters or collection terminals / concentrators of different sizes, and improving the compatibility of this application.

[0035] During the process of transporting the electricity meter by the adjustable belt line 6 and the fixed belt line 4, when the electricity meter is being positioned by the positioning device 5, the positioning telescopic rod 10 is started. The positioning telescopic rod 10 drives the positioning box 12 to slide along the support frame. The positioning box 12 pushes the electricity meter through the rotating roller 13 on the pushing frame for the initial positioning and reset; after the electricity meter is initially positioned and reset, the pushing frame and the rotating roller 13 on it are retracted to limit the electricity meter.

[0036] According to the size of the electricity meter, the adjusting motor 18 is started. The adjusting motor 18 drives the adjusting double crank 23 to rotate. The adjusting double crank 23 drives the adjusting rod 24 to rotate. The adjusting rod 24 drives the connecting block 22 to slide along the positioning box 12, so that the vertical groove 33 corresponds to the electricity meter; the clamping motor 16 is started. The clamping motor 16 drives the clamping double crank 17 to rotate. The clamping double crank 17 drives the clamping block 21 to slide along the positioning box 12 through the clamping rod 19.

[0037] The clamping block 21 drives the driving wheel 37 to move along the driving rack 25. Under the action of the driving rack 25, the driving wheel 37 rotates. The driving wheel 37 drives the rotating frame 26 to rotate. At this time, the roller 38 on the rocker 28 is in the movable groove 35; since the rotating frame 26, the connecting rod 27, and the rocker 28 form a crank-rocker 28 mechanism, when the rotating frame 26 rotates, the rotating frame 26 drives the rocker 28 to rotate within a certain angle range through the connecting rod 27. The rocker 28 drives the driving rod 29 to rotate; since the driving rod 29, the driven rod 31, and the parallel rod 30 form a parallelogram mechanism, when the driving rod 29 rotates, the driving rod 29 drives the parallel rod 30 to move horizontally and back and forth through the driven rod 31. The parallel rod 30 drives the clamping plate 14 to move horizontally and back and forth to position the electricity meter; during the positioning process, the electricity meter is reset under the action of the force of the clamping plate 14 moving back and forth and the force of the belt line itself resetting; when the clamping plate 14 drives the electricity meter to move horizontally and back and forth through the anti-slip pad 15, the front and back movement of the electricity meter is limited by a plurality of the rotating rollers 13, and the horizontal movement of the electricity meter is guided by the rotation of the rotating rollers 13 to improve the stability of the movement of the electricity meter.

[0038] When the driving wheel 37 moves with the clamping block 21 to the separation plate 36, the positioning box 12 pushes and positions the electricity meter through the rotating roller 13 on the pushing frame, so that the electricity meter is positioned in the front and back directions; the clamping block 21 continues to move. The clamping block 21 drives the roller 38 on the rocker 28 to move to the rotating slope 34. Under the action of the rotating slope 34 and the roller 38, the rocker 28 is driven to rotate. The rocker 28 drives the driving rod 29 to rotate to a state where it is vertical and flush with the clamping plate 14. The clamping block 21 continues to move, so that the driving rod 29 cooperates with the clamping plate 14 to fix the electricity meter, and the electricity meter is positioned in the horizontal direction.

[0039] After the electric energy meter is correctly positioned and fixed, the clamping block 21, the alignment box 12, etc. move in the reverse direction away from the electric energy meter, and the electric energy meter is conveyed to the next station for verification under the action of the adjusting belt line 6 and the fixed belt line 4.
