Description

Technical Field

[0001] The invention belongs to the technical field of quality inspection equipment, and in particular relates to a safety detection device for a smart electric meter. Background Art

[0002] The abbreviation of electric energy meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, energy meter, kilowatt-hour meter, which refers to instruments for measuring various electrical quantities. The electric energy meter detection device is specially designed for the power system to test the operation error and fault detection of electric energy meters, so that operators can quickly, safely and reliably measure the meter errors and wiring errors, providing an effective basis for the power system metering personnel to correctly measure and make up the electricity.

[0003] Problems with existing technologies:

[0004] The existing electric energy meter detection equipment generally has the following shortcomings:

[0005] The testing function is single. Most testing equipment can only complete a single test item. The finished product needs to be constantly transferred between various equipment to complete the corresponding test. This will lead to a too long quality inspection process, and multiple equipment and transportation lines will take up too much space;

[0006] The equipment has high energy consumption. In an entire test production line, the investment in test equipment and the operation of transportation equipment will generate huge electricity consumption. The products will be driven by corresponding power equipment during transportation, loading and unloading, and testing, resulting in excessive investment in power equipment. Due to the singleness and independence of the test equipment functions, the entire optimization of the power equipment investment plan becomes more difficult. Summary of the invention

[0007] The purpose of the present invention is to provide a smart meter safety detection device, which provides a device for detecting air tightness and switch load, both of which adopt a multi-station working mode.

The structure is compact and flexible, and the operation is more automated.

[0032] In the present invention, the process of the clamp mechanism taking the finished product utilizes the original negative pressure in the negative pressure tank as power, and lowering the finished product is completed by closing the valve and moving the push rod rack downward, and the closing of the valve and the downward movement of the push rod rack are both controlled by a cylinder. The entire process of taking and lowering does not require frequent operation of traditional pump power equipment, and only the negative pressure in the negative pressure tank needs to be regularly supplemented by an air pump, thereby further reducing the energy consumption of the entire device.

[0066] See attached Fig. 9 and Fig.10A transmission shaft 711 is rotatably assembled inside the joint platform 105 and near the motor 1 709. A bevel gear 2 712 meshing with the corresponding bevel gear 1 402 is fixedly installed at one end of the transmission shaft 711. A slide tube 2 713 is slidably assembled at the other end of the transmission shaft 711. An outer bevel gear 1 714 is fixedly arranged at one end of the slide tube 2 713.

[0067] See attached Fig. 9 and Fig.10 , a gear lever 717 for controlling the sliding of the slide tube 2 713 is rotatably connected inside the joint platform 105 through a bracket 716, a rotating rod 718 is rotatably assembled at the bottom of the guide roller 1 201 near the secondary crawler 4, both ends of the rotating rod 718 are fixedly connected to a pry bar 1 719, one end of the pry bar 1 719 is rotatably connected to a connecting rod 720, the ends of two adjacent connecting rods 720 are commonly connected to a lever 1 721, and the lever 1 721 movably passes through the bottom end of the gear lever 717; a rotating rod 722 is rotatably connected inside the joint platform 105 and located on both sides of the bracket 716, the tops of two adjacent rotating rods 722 are commonly connected to a lever 2 723, and the lever 2 723 is movably connected to the upper half of the gear lever 717, and the horizontal height of the support 708 is flush with the lower half of the pry bar 1 719 and the part of the rotating rod 722 near the transition.

[0068] According to the above structure, firstly, two metering molds 3 are equipped on a detection line to carry out two detection tasks simultaneously. After the airtightness detection work is completed, the metering mold 3 is transferred to the surface of the secondary crawler 4 through the crawler machine 2 and waits. When the load test work is completed, the motor 709 is started. Since the outer bevel gear 714 is meshed with the inner bevel gear 710 at this time, the motor 709 can simultaneously drive the transmission shaft 711 and the two screws 701 to rotate. The transmission shaft 711 can drive the secondary crawler 4 to operate and move the metering mold 3 of the starting section to the load test station; and since the screw 701 is screwed with the screw tube 702, and the rectangular guide block 307 is placed inside the rectangular block support 705, the metering mold 3 on the original load test station is driven by the rectangular block supports 705 on both sides to move in the opposite direction. According to the shape of the inner guide frame 61 and the outer guide frame 62, it is elastic. Under the elastic force of the spring 707, the side triangular guide block 306 directly enters the interior of the inner guide frame 61 from the entrance 611, and the meter setting mold 3 will also directly detach from the secondary crawler 4 and move obliquely upward. After the side triangular guide block 306 is led out from the exit 612, the two meter setting molds 3 can complete the position change; the above process can enable the meter setting mold 3 that has completed the air tightness test to finally move to the load test station, and the meter setting mold 3 that has completed the load test will be transported to the loading and unloading area at one end of the crawler machine 2, so that the two meters can be replaced after completing different detection tasks together and each and simultaneously enter the preparation for the corresponding other detection task, wherein the setting of the side triangular guide block 306 can ensure that the meter setting mold 3 is in a horizontal state during its movement along the inner guide frame 61, and cooperate with the combination of the rectangular guide block 307 and the rectangular block support 705 to prevent the meter setting mold 3 from overturning;

[0069] Furthermore, during the process of one of the meter placement molds 3 moving toward the load test station, the guide rod 1 305 will simultaneously enter the inclined guide frame 5. During the process, the magnetic blocks 303 on both sides of the meter placement mold 3 will simultaneously slide upward along the vertical guide grooves 302. Under the magnetic force between the magnetic blocks 303 and the L-shaped frame rod 301, the inner L-shaped frame rod 301 will carry the internal electric meter and move up one end distance, so that the electric meter exposes the power connection point, which is convenient for subsequent contact with the load test body 813. The above process can smoothly connect the load test work with the air tightness test work, ensure the automatic alignment of the electric meter and the contact test with the load test body 813, make the dual test work both reasonable and practical, and further improve the automation effect of the entire equipment.

[0070] Furthermore, when the corresponding table mold 3 moves to the limit position in the upward unloading area, the support frame 708 at the bottom of the screw tube 702 will be squeezed with the lower half of the pry bar 1 719 to rotate the pry bar 1 719, and the pry bar 1 719 will make the lever 1 721 move the bottom end of the gear lever 717 through the connecting rod 720. At this time, the top of the gear lever 717 will move the slide tube 2 713 to separate the outer bevel gear 1 714 from the inner bevel gear 1 710. Then, the control motor 1 709 is reversed. At this time, the motor 1 709 only drives the screw rods 1 701 on both sides to reverse, and then the two screw tubes 702 will be reset and the secondary crawler 4 will not operate. Finally, when the two screw tubes 702 are reset to the limit position, the support frame 708 will be squeezed with the rotating rod 722 again, and the rotating rod 722 will then pass through the lever 2 72 3 reversely toggle the shift lever 717 and make the outer bevel gear 1 714 and the inner bevel gear 1 710 resume meshing, so as to facilitate the next process of transposing the two table molds 3; in the above process, the setting of the transposition power assembly 7 enables the secondary crawler 4 to drive the table mold 3 to move, and the other table mold 3 to move to the upper and lower material area, which can be controlled by a motor 1 709, further optimizing the use of power equipment of the entire device, reducing the investment in power equipment and reducing the consumption of electric energy as much as possible, in addition, the movement of the solenoid 702 is synchronized with the operation of the secondary crawler 4 and in a different direction, while the resetting of the solenoid 702 is not related to the secondary crawler 4, under the premise of ensuring that the transposition work of the double table mold 3 can be carried out continuously, it will not affect the progress of the load test work, the structure is compact and flexible, and the operation is more automated.

[0071] The working principle of the present invention is: Figure 7 As shown, two metering molds 3 are equipped on one inspection line to perform two inspections simultaneously. After the airtightness inspection is completed, the metering mold 3 is transferred to the surface of the secondary crawler 4 through the crawler machine 2 and waits. After the load test is completed, the motor 709 is started. Since the outer bevel gear 714 is meshed with the inner bevel gear 710 at this time, the motor 709 can simultaneously drive the transmission shaft 711 and the screws 701 on both sides thereof to rotate together. The transmission shaft 711 can drive the secondary crawler 4 to operate through the meshing of the bevel gear 1 402 and the bevel gear 2 712, thereby moving the metering mold 3 of the starting section to the load test station;

[0072] Since the screw rod 701 is screwed with the screw tube 702 and the rectangular guide block 307 is placed inside the rectangular block support 705, the table setting mold 3 originally in the load test station is driven by the rectangular block supports 705 on both sides to move in the opposite direction. According to the shapes of the inner guide frame 61 and the outer guide frame 62, and under the elastic force of the spring 707, the side triangular guide block 306 directly enters the inner guide frame 61 from the entrance 611, and the table setting mold 3 will also directly detach from the secondary crawler 4 and move obliquely upward, waiting for the side triangular guide block 3 06 After being led out from the outlet 612, the two table setting molds 3 can be replaced, and the table setting mold 3 that has completed the air tightness test is finally moved to the load test station, and the table setting mold 3 that has completed the load test is transported to the loading and unloading area at one end of the crawler machine 2, wherein the setting of the side triangular guide block 306 can ensure that the table setting mold 3 is in a horizontal state during its movement along the inner guide frame 61, and cooperates with the combination of the rectangular guide block 307 and the rectangular block support 705 to prevent the table setting mold 3 from overturning;

[0073] During the movement of the meter placement mold 3 toward the load test station, the guide rod 1 305 will simultaneously enter the inclined guide frame 5. During the process, the magnetic blocks 303 on both sides of the meter placement mold 3 will simultaneously slide upward along the vertical guide grooves 302. Under the magnetic force between the magnetic blocks 303 and the L-shaped frame rod 301, the inner L-shaped frame rod 301 will carry the internal electric meter and move up a distance, so that the electric meter exposes the power connection point, which is convenient for subsequent contact with the load test body 813.

[0074] Finally, when the two screw tubes 702 cooperate with the corresponding surface mold 3 to move to the upper feeding area to the limit position, the support frame 708 at the bottom of the screw tube 702 will squeeze the lower half of the pry bar 1 719 to rotate the pry bar 1 719, and the other end of the pry bar 1 719 will make the lever 1 721 move the bottom end of the gear lever 717 through the connecting rod 720, and at this time, the top of the gear lever 717 will move the slide tube 2 713 to separate the outer bevel gear 1 714 from the inner bevel gear 1 710, and then the control motor 1 7 09 reverses, at this time, the motor 709 only drives the screw rods 701 on both sides to reverse through the chain 715, and then the two screw tubes 702 will be reset and the secondary crawler 4 will not operate. Finally, when the two screw tubes 702 are reset to the limit position, the support frame 708 will be squeezed with the rotating rod 722 again, and the rotating rod 722 will then reversely shift the gear lever 717 through the shift lever 723 to make the outer bevel gear 714 and the inner bevel gear 710 resume meshing, so as to facilitate the next process of the two-position table mold 3 replacement. Embodiment three:

[0075] See attached Fig.13 and Fig.14The clamp mechanism 10 includes a climbing machine 1001 which is assembled with the track machine 901 in a lifting manner, and a clamping disc 1002 is fixedly installed at the bottom of the climbing machine 1001, and suction cups are arranged at the four corners of the lower surface of the clamping disc 1002, and suction pipes 1003 are connected to the positions of the suction cups on the surface of the clamping disc 1002, and the ends of all the suction pipes 1003 are commonly connected to a main pipe 1004, and a valve 1005 is fixedly installed at one end of the main pipe 1004, and a push-type switch 1006 for controlling the dredging of the pipeline is installed at one end of the valve 1005; a push rod frame 1010 for separating the electric meter from the clamping disc 1002 is slidably assembled on one side of the suction cup, and the surface of the clamping disc 1002 is A pry bar 1009 is rotatably installed on one side, and one end of the pry bar 1009 is connected to the rod body in the middle of the push rod frame 1010; a cylinder 3 1008 is fixedly installed on one side of the climbing machine 1001 through an integrated back frame 1007, and the end of the telescopic output end of the cylinder 3 1008 is connected to the other end of the pry bar 1009, and a block 1011 for squeezing the push switch 1006 is fixedly provided on the side wall of the telescopic output rod of the cylinder 3 1008; a negative pressure tank 11 and an air pump 12 are provided on one side of the bottom of the airtightness detection body 1, and the output port of the negative pressure tank 11 is connected to the end of the main pipe 1004, and the input port of the negative pressure tank 11 is connected to the air pump 12 through a pipeline.

[0076] According to the above structure, when the chuck 1002 is close to and is about to pick up the corresponding electric meter, the cylinder three 1008 is controlled to extend, and the push rod frame 1010 is moved up through the lever movement of the pry bar two 1009 to prevent it from affecting the operation of the suction cup. At the same time, the stop block 1011 is away from the push switch 1006, and the valve 1005 is opened. Under the negative pressure of the negative pressure tank 11, each suction tube 1003 will generate suction, and the electric meter will be adsorbed by the suction cup under the action of the suction force. Subsequently, the electric meter is controlled to move to the corresponding position and lowered. Next, the cylinder three 1008 is controlled to contract, and the stop block 1011 will squeeze the push switch 1006 and The valve 1005 is closed, and the suction force on the electric meter disappears. At the same time, the push rod frame 1010 will move downward and assist the electric meter to separate from the suction cup. In the above process, the clamp mechanism 10 takes the finished product by utilizing the original negative pressure in the negative pressure tank 11 as the power, and the lowering of the finished product is completed by closing the valve 1005 and moving down the push rod frame 1010. The closing of the valve 1005 and the downward movement of the push rod frame 1010 are both controlled by a cylinder 1008. The entire process of taking and lowering does not require the frequent operation of traditional pump power equipment. It is only necessary to regularly replenish the negative pressure in the negative pressure tank 11 through the air pump 12, which further reduces the energy consumption of the entire device.

[0077] The working principle of the present invention is as follows: the track machine 901 and the climbing machine 1001 are used to control the chuck 1002 to move toward the meter placement mold 3 on the corresponding loading and unloading area. When the chuck 1002 is close to and about to take the corresponding electric meter, the cylinder 3 1008 is controlled to extend and move, and the push rod frame 1010 is moved up by the lever movement of the pry bar 2 1009 to avoid affecting the work of the suction cup. At the same time, the block 1011 is away from the push switch 1006, and the valve 1005 is opened, and the negative pressure tank 1 1, each suction tube 1003 will generate suction, and the electric meter will be adsorbed by the suction cup under the action of the suction, and then the electric meter will be controlled to move to the corresponding finished product belt machine 13, airtight defective belt machine 14 or load defective belt machine 15, and then the cylinder three 1008 will be controlled to contract, the block 1011 will squeeze the push switch 1006 and close the valve 1005, and the suction on the electric meter will disappear. At the same time, the push rod frame 1010 will move downward and assist the electric meter to separate from the suction cup.

[0078] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
