Description

Technical Field

[0001] The present invention relates to the technical field of installation and positioning of electric meter boxes, and in particular to an installation and positioning device and a positioning method for an electric meter box. Background Art

[0002] The electric meter box is a protective device specially used to install electric energy metering instruments (such as electric meters). It can protect the electric energy metering instruments and lines and prevent the electric energy metering instruments from running unstably or causing safety hazards due to external factors.

[0003] Before installing the meter box, it is necessary to mark the wall where it needs to be installed according to the installation hole position of the meter box to determine the position of the drilling hole. When marking the hole position of the drilling hole, the meter box needs to be at a certain distance from the ground. At the same time, the meter box must be installed vertically and the deviation from the vertical position after the meter box is fixed must not exceed 5 degrees. If the installation is tilted greatly, it will cause a large error in the measurement. During manual installation, the installer needs to manually measure the relative distance between the holes and then mark the holes, or one person presses the meter box against the wall, and the other person uses a pencil to mark the wall according to the installation hole position of the meter box. Both of them are difficult to ensure whether the meter box itself is level. At the same time, manual operation is cumbersome and laborious, and even requires the assistance of multiple people.

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0040] like Figure 1-Figure 6 As shown, a meter box installation positioning device includes:

[0041] A fixed plate 1, with an adhesive portion fixedly connected to the bottom;

[0042] A magnetic chuck 11, the bottom of which is fixedly connected to the fixed plate 1, a shield 12 is magnetically attracted to the top of the magnetic chuck 11, and a fixed shaft 13 is fixedly connected at the center of the shield 12;

[0043] A first bearing 14, the inner end of which is fixedly connected to the fixed shaft 13, and the outer end of which is fixedly connected to the horizontal positioning mechanism 2;

[0044] A cross positioning mechanism 3, fixedly connected to the top of the horizontal positioning mechanism 2;

[0045] With the fixed axis 13 as the origin center, the horizontal positioning mechanism 2 is used to locate the longitudinal height of the drilling position. On the basis of horizontal positioning and leveling, with the horizontal positioning mechanism 2 as the reference, the cross positioning mechanism 3 is used to locate the lateral distance of the drilling position, thereby determining the drilling position;

[0046] In this way, the adhesive portion of the fixing plate adheres the fixing plate to the wall, and the magnetic suction cup 11 allows the protective cover 12 to be easily magnetically mounted on the magnetic suction cup 11, and the position of the protective cover 12 can be fine-tuned.

[0047] As an optional implementation, Figure 2 and Figure 3As shown, the horizontal positioning mechanism 2 includes a cross bracket 21, the left and right ends of the cross bracket 21 include two mirror-symmetrical transverse arms 211, the upper and lower ends of the cross bracket 21 include two mirror-symmetrical longitudinal arms 22, the intersection of the two transverse arms 211 and the center extension lines of the two longitudinal arms 22 is fixedly connected with a mounting block 23, the inner circle end of the mounting block 23 is fixedly connected to the outer circle end of the first bearing 14, the two longitudinal arms 22 and the two transverse arms 211 are fixedly connected to the mounting block 23, and the ends of the two transverse arms 211 are each hinged with a counterweight lead pendulum 212;

[0048] In this way, the hinged counterweight lead pendulum 212 keeps the cross support 21 horizontal under the action of gravity, thereby achieving automatic leveling.

[0049] As an optional implementation, Figure 2 and Figure 3 As shown, the horizontal positioning mechanism 2 also includes a U-shaped bracket 221 fixedly connected to the ends of the two longitudinal arms 22, and a dual-axis motor 222 is fixedly connected to the inner side of each of the U-shaped brackets 221. The two ends of the main shaft of each of the dual-axis motors 222 pass through the U-shaped bracket 221 and are respectively fixedly connected to two first transmission pulleys 223. The front end of the U-shaped bracket 221 is also rotatably connected to a laser component, and the two ends of the laser component are rotatably connected to the U-shaped bracket 221. Two second transmission pulleys 224 are fixedly connected to the two ends of the laser component, and a transmission belt 225 is transmission-connected between each first transmission pulley 223 and the second transmission pulley 224;

[0050] In this way, when the cross support 21 is kept horizontal, the rays emitted by the laser assembly are also horizontal.

[0051] As an optional implementation, Figure 2 and Figure 3 As shown, the laser assembly includes a first green laser line projector 24 rotatably connected to the inner side of the U-shaped bracket 221 and a laser distance measuring sensor 25 fixed in the middle of the green laser line projector;

[0052] Thus, the laser distance sensor 25 is used to sense the distance between two points, and the green laser line projector is used to emit a long laser line as a marking aid.

[0053] As an optional implementation, Figure 2 and Figure 3 As shown, the cross positioning mechanism 3 includes a driving motor 31 fixedly connected to the top of the mounting block 23, and a second green laser line projector 33 is fixedly connected to the top of the main shaft of the driving motor 31;

[0054] In this way, the ray emitted by the cross positioning mechanism 3 is a straight line that rotates around the axis of the fixed shaft 13 and is emitted toward the wall.

[0055] As an optional implementation, Figure 2 and Figure 3 As shown, the top of the mounting block 23 is also fixedly connected to a second bearing 32, the outer circular end of the second green laser line projector 33 is fixedly connected to the inner circular end of the second bearing 32, and the ray angle of the second green laser line projector 33 is inclined toward the fixed plate 1;

[0056] In this way, the second bearing 32 ensures that the second green laser projector 33 rotates stably.

[0057] As an optional implementation, the laser emission points of the first green laser line projector 24 and the laser distance sensor 25 are located at the rotation axis of the first green laser line projector 24;

[0058] In this way, when the main shaft of the dual-axis motor 222 rotates, the injection height will not change.

[0059] As an optional implementation, Figure 2 and Figure 3 As shown, the outer circumferential end of the second bearing 32 is fixedly connected to the shield 12, and the circumferential surface of the shield 12 is made of transparent material;

[0060] In this way, without affecting the operation of the laser distance measuring sensor 25, the first green light projector and the second green light projector, the internal structure is protected from external influences, such as wind and sand, thereby ensuring the accuracy of the device.

[0061] As an optional implementation, Figure 1 As shown, a control panel 34 is fixedly connected to the top of the shield 12, and a control button 35 and a display screen 36 are arranged on the control panel 34. A processor and a data transmission module are arranged inside the control panel 34;

[0062] In this way, the part that requires complex calculations is executed by the processor by interacting with the user through data transmission.

[0063] A positioning method for installing a positioning device for an electric meter box, such as Figure 3-Figure 6 As shown, the positioning method includes:

[0064] S1: Glue the fixing plate 1 to the wall to be installed, then magnetically attach the shield 12 to the magnetic chuck 11, and wait for the horizontal positioning mechanism 2 to automatically maintain a horizontal state due to gravity;

[0065] S2: Turn on the laser assembly to rotate the main shaft of the dual-axis motor 222, so that the laser distance sensor 25 works, and the sensed distance is recorded as H. The actual distance from the ground is H minus the distance from the axis of the fixed axis 13 to the lower edge of the meter box. After the actual distance from the ground is appropriate, the fixed axis 13 is taken as the center of the coordinate origin. The origin coordinate position takes the intersection of the center of the outer dimension of the meter box. The orthogonal line centered on the origin is the coordinate axis, and the other hole positions are divided into four quadrants and the coordinate axis, and the coordinates of the position to be punched relative to the origin are input to the processor. According to the height position of the installation hole, the first transmission pulley 223 drives the second transmission pulley 224 to rotate by driving the dual-axis motor 222, thereby driving the laser distance sensor 25 and the first green laser line projector 24 to rotate, and project the wall for measurement. The measured distance between the laser distance sensor 25 and the wall is recorded as a, the vertical distance between the laser distance sensor 25 and the wall is a fixed value b, the distance between the laser sensor emission point and the axis of the fixed axis 13 is c, and the longitudinal height of the hole relative to the origin is recorded as y;

[0066] S3: Turn on the second green laser line projector 33 to project a laser line onto the wall. The horizontal distance of the hole relative to the origin is recorded as x. The rotation angle of the second green laser line projector 33 is calculated according to the values ​​of x and y and recorded as e. The intersection of the lines projected by the first green laser line projector 24 and the second green laser line projector 33 is the drilling point.

[0067] S4: Based on the values ​​in S1-S3, the conversion method is:

[0068] ;

[0069] ;

[0070] S5: After the processor completes the calculation and makes the projection lines of the first green laser line projector 24 and the second green laser line projector 33 intersect with the wall surface, the intersection point is marked as a punching point.
