Description

Technical Field

[0001] The utility model relates to the technical field of angle detection and height warning, and in particular to an angle deviation detection correction and height warning device. Background Art

[0002] During the construction and installation of buildings, power and other projects, there are certain requirements for the installation angles of equipment and facilities. They must meet the angle deviation range to be considered qualified, so the control of angle deviation is very critical. For example, in power grid operation, maintenance, infrastructure projects and other occasions, ladders are widely used. The "Safety Regulations" and other operating procedures have strict regulations on the use of ladders, including: Ladders should be installed securely during use and the angle between the ladder and the ground should be 60°. If used improperly, accidents are very likely to occur.

[0003] According to the "Safety Regulations", any work that is more than 2 meters above the ground (the reference datum plane during the operation) is considered high-altitude work and safety belts should be used as required. Failure to use safety belts as required is considered an illegal operation and there is a risk of falling from a height.

[0004] At present, in daily work, there is a lack of detection means for the angle between the ladder and the ground, and the ladder is erected based on the experience of the staff. There is no guarantee that the angle between the ladder and the ground meets the use requirements. If the angle is too large, the ladder may easily fall backward during use; if the angle is too small, it may be difficult for operators to climb, and the ladder may easily be deformed or damaged, causing personal injury, posing a major safety hazard; in the process of climbing the ladder, there is no means to detect the distance between the operators and the ground, and the operators are not reminded to use the safety belts as required when they climb to 2 meters from the ground.

[0005] Therefore, the current method of using ladders has serious drawbacks. First, the ladder is erected based on the staff's experience, and the angle between the ladder and the ground cannot be measured, resulting in a blind spot in use. Second, no early warning can be given when there is an angle problem during ladder erection. Third, there is no ladder angle correction method to guide staff to carry out angle correction until the application requirements are met. Fourth, there is no device for detecting or prompting the operator's distance to the ground. Utility Model Content

[0006] The main purpose of the utility model is to provide an angle deviation detection correction and height warning device, aiming to solve the technical problem that the prior art cannot measure the ladder angle, and then correct the ladder according to the angle, and at the same time has no distance to the ground detection and prompt.

[0007] To achieve the above object, the utility model provides an angle deviation detection correction and height warning device, comprising: a fixing frame, the fixing frame is equipped with an angle measuring instrument through a countersunk screw, and the angle measuring instrument is connected with a plumb bob device through a plumb line;

[0008] The angle measuring instrument is arranged horizontally, and the surface thereof is divided into warning zones by scales, the scales between -5° and 5° are the reasonable zone, the scales between -5° and -10° and between 5° and 10° are the adjustment zone, and the scales between -10° and -90° and between 10° and 90° are the unqualified zone.

[0009] Furthermore, the plumb line points to a ° reference when the angle measuring instrument is horizontal, and the height of the plumb line is meters.

[0010] Furthermore, the angle between the angle measuring instrument and the fixing frame is °, the fixing frame is detachably mounted on the ladder via a fixing nut, and the fixing frame is parallel to the ladder.

[0011] Furthermore, a rotating shaft is provided at the center of the angle measuring instrument, a rotating drum is rotatably mounted on the rotating shaft through a nut, and the plumb line is tied to the rotating drum.

[0027] The angle measuring instrument 4 is arranged horizontally, and the surface thereof is divided into warning zones by scales, the scales between -5° and 5° are the reasonable zone, the scales between -5° and -10° and between 5° and 10° are the adjustment zone, and the scales between -10° and -90° and between 10° and 90° are the unqualified zone.

[0029] Detection and correction principle

[0030] The main scheme of the present invention is to adopt the physical principle that the plumb line always remains perpendicular to the horizontal plane, combined with the plane geometry principle that the sum of the interior angles of a triangle is 180°, firstly, a measuring point is set, and a plumb line is drawn from the measuring point to always remain perpendicular to the horizontal plane (that is, the angle between the plumb line and the ground is 90°). Secondly, an auxiliary side is set, the auxiliary side intersects with the plumb line, and the plane determined by the auxiliary side and the plumb line intersects with the horizontal plane perpendicularly, so that the angle ∠a formed by the auxiliary line and the horizontal plane and the angle ∠b formed by the auxiliary line and the plumb line are complementary angles, that is, ∠a+∠b=90°. The third is to set up an angle measuring device, whose reference point (zero point) is set at the intersection of the auxiliary side and the plumb line. When ∠a is 60°, the pointer of the angle measuring device coincides with the plumb line, and the degree is 0° at this time, proving that the angle of the installation or erection equipment meets the requirements and there is no deviation; the state at this time is divided into positive deviation area and negative deviation area based on the plumb line, and the two areas are distinguished by different colors. At the same time, the reading of the angle measuring device is: (∠a-60°), which will meet the angle deviation alarm and angle correction functions. A heavy object (plumb) is hung on a 2-meter-long thin line and fixed at the origin of the angle measuring device to replace the function of the pointer. At the same time, during use, the plumb is in contact with the ground. At this time, the vertical distance between the angle measuring device and the ground is about 2 meters. When the operator reaches the position of the angle measuring device during climbing the ladder, it can remind the operator to use the safety belt as required.

[0031] During use, by observing the scale of the angle measuring instrument, when the angle ∠a between the ladder and the ground is 60°, the scale reading is 0°; when ∠a is not equal to 60°, the scale reading is (∠a-60°). Prompt intervals can also be set on the dial and distinguished by color. For example, with 60° as the reference, the ±5° range is the safety zone, marked in green; ±5°<deviation ≤±10° is the adjustment zone, marked in yellow; deviation>±10° is the unqualified zone and is prohibited from use. The above will realize the angle deviation detection and correction function.

[0032] The distance between the plumb line and the ground is 2 meters in length. During use, the plumb bob device is required to be in contact with the ground. Then the vertical distance between the fixed point of the angle measurer and the ground is 2 meters. When the operator climbs to the fixed point of the angle measurer, the operator is reminded to use the safety belt correctly, thereby realizing a real-time early warning function for the operator's working height.

[0033] In some embodiments, see Figure 2 and 3 As shown, the plumb line 5 points to the 0° reference when the angle measuring instrument 4 is horizontal, and the height of the plumb line 5 is 2 meters.

[0034] In some embodiments, see Figure 3 and 4 As shown in Figures 5 and 6, the angle between the angle measuring instrument 4 and the fixing frame 2 is 60°. The fixing frame 2 is detachably mounted on the ladder 1 via a fixing nut 3, and the fixing frame 2 is parallel to the ladder 1.

[0035] In some embodiments, see Figure 4 As shown, a rotating shaft 4 a is provided at the center of the angle measuring instrument 4 , a rotating drum 7 is rotatably mounted on the rotating shaft 4 a through a nut 9 , and the plumb line 5 is tied to the rotating drum 7 .

[0036] In some embodiments, see Figure 4 As shown, the rotating shaft 4a is symmetrically provided with mounting protrusions 4b on both sides, and the mounting protrusions 4b are provided with countersunk holes, and the countersunk screws 8 are installed on the fixing frame 2 through the countersunk holes.

[0037] In some embodiments, see Figure 2 As shown, the fixing frame 2 is installed at a distance of 2 meters from the ground.
