Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a big stroke line plummet device for building engineering construction. BACKGROUND

[0002] In the process of building engineering construction, it is usually necessary to use a line plummet to measure and position the perpendicularity of a building, the flatness of a wall surface and the like, and to determine the horizontal and vertical positions of key points. The line plummet commonly used in the prior art is also known as a plumb bob, and usually comprises three parts of a weight (plumb bob), a hanging line and a suspension device. The weight is usually conical or cylindrical and is made of lead or other high-density metal. The center of gravity of the weight is stable, and it can always point to the center of the earth, i.e. the vertical direction, under any circumstances. The line rope is an elongated rope connecting the weight and the suspension point. The hanging line is usually made of cotton thread, nylon thread or steel wire, and has good flexibility and wear resistance. Its length and diameter can be determined according to the requirements of use to meet the measurement requirements of different heights. The suspension device is a device for fixing the upper end of the line rope, facilitating suspension and operation. It can be a simple hook, clamp or a more complex fixing device, such as a magnetic plumb bob fixing needle.

[0003] Generally speaking, in building construction, the line laying stroke of the line plummet should be long enough to cover the vertical distance to be measured, but the line laying stroke of the line plummet in the prior art is usually within 10 meters. The reason is that, on the one hand, the hanging line needs to be arranged during line laying, and a too long hanging line is difficult to arrange; on the other hand, during the line laying process, the plumb bob descends too fast, has a large impact force and a large swing amplitude when the hanging line is too long, and has poor stability, which can easily affect the measurement and positioning accuracy. Therefore, a too long hanging line will correspondingly increase the technical difficulty of operation, and cannot maintain continuous stability during use, and is easily disturbed by external factors.

[0004] In the prior art, the utility model discloses a building engineering construction line plummet device, which comprises a box body, a vertical pipe, a cover body, a sleeve, a rotating shaft, a take-up reel and other components, the position of the take-up reel is limited by the cooperation of the rotating plate, the inserting rod, the limiting ring, the spring and the limiting block, and the wire length is controlled, however, the device is complex in structure, large in size, inconvenient to carry and install, and the wire length is still limited by the box body, so it cannot meet the needs of the construction of a wire body with a stroke of 20m or more (such as a building with more than four floors), although the patent technology can release the winding line and perform the line laying operation, if the line laying stroke of the wire body is increased, the weight of the plumb body must also be increased, when the line is laid, the plumb body with large weight is released from the fixing, and the wire body is driven to move downward at high speed, so that the line plummet is prone to large swing amplitude during the downward movement and the construction process, and the accuracy of measurement and positioning is affected, and in addition, the impact force generated by the plumb body with large weight when stopping the line laying is also large, so the service life of the line plummet device is affected.
