Description

Technical Field

[0001] The utility model belongs to the technical field of boiler installation, and specifically relates to a measuring device for heating boiler installation. Background Art

[0002] During the installation of a heating boiler, measurement is a critical step, the main purpose of which is to ensure the accurate installation of the boiler and the rationality of the location layout. A heating boiler is generally composed of a tank body and the steel rails underneath. During installation, holes are pre-drilled on the cement platform, the steel rails are fixed with bolts, and then the tank body is placed on the rails.

[0003] The rails are installed first, so that the tank can be quickly positioned. First, the rails are accurately arranged according to the construction drawings, and then the distance between the rails is measured using a laser rangefinder. Next, the rails are adjusted using a level to make them completely horizontal. After placing the boiler on the rails, the inclination of the boiler is measured using a level, and the distance between the boiler and the rails is measured using a laser rangefinder, so as to obtain the precise values ​​of the boiler installation coordinates.

[0004] During the positioning process before installation, the rails need to first reach the preset position on the construction drawing and then be leveled using a level. However, there are generally two rails, which are relatively isolated from each other and often need to be positioned and measured separately, which is not conducive to reducing the burden of positioning and measurement. For this reason, we propose a measuring device for heating boiler installation. Utility Model Content

[0005] The purpose of the utility model is to provide a measuring device for heating boiler installation, which links the installation measurements of two rails with each other, can find and mark the installation positions of the two rails at one time, and is conducive to reducing the burden of positioning measurement.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A measuring device for heating boiler installation comprises a steel ruler plate, wherein a step hole is vertically provided in the middle of the steel ruler plate, the size of the upper opening of the step hole is larger than the size of the lower opening, two parallel movable rulers are slidably installed at positions on both sides of the step hole on one side of the steel ruler plate, through holes are horizontally provided in the middle of the two movable rulers, and perforated plates are slidably installed on the upper surfaces of the two movable rulers, and the through holes of the two perforated plates are respectively opposite to the two through holes. When working, the step hole of the steel ruler plate is aligned with the first hole, and the steel ruler plate is straightened in the direction of the construction drawing to keep the water level. Then, take the step hole as the base point and, according to the parameters of the construction drawing, translate the two movable rulers to the specified position along the horizontal scale on the steel ruler plate. Keep the two movable rulers horizontal and mark the lower edge of the steel ruler plate with chalk to measure the installation position of one of the rails. Then, move the two perforated plates to the specified position along the vertical scale, align with the two screw holes of the other rail, use a drill to drill vertically, and measure the installation position of the other rail. By linking the installation measurements of the two rails, the installation positions of the two rails can be found and marked at one time, which helps to reduce the burden of positioning measurement.

[0008] At least two first horizontal bubble tubes are fixed on the side of the steel ruler away from the movable ruler, and the central axes of the first horizontal bubble tubes are parallel to the central axis of the steel ruler. The first horizontal bubble tubes are used to indicate the horizontal level of the steel ruler. The corresponding end of the steel ruler is raised according to the direction to which the bubble deviates until the bubble is centered.

[0009] A guide rail is fixed axially on the outer side of the steel ruler plate, and the guide rail passes through two movable rulers. The two movable rulers are moved along the guide rail to facilitate straightening and reduce the degree of skewness.

[0010] A second horizontal bubble tube is fixed on one side of the two perforated plates, and the central axis of the second horizontal bubble tube is parallel to the central axis of the perforated plates. The second horizontal bubble tube is used to indicate the horizontality of the corresponding perforated plates along the longitudinal direction, and it is leveled and straightened by hand in time.

[0011] A plurality of magnetic sheets are arranged in sequence from top to bottom along the lower edges of the two perforated plates away from the steel ruler plate. The thickness of the magnetic sheets is relatively small. When the number of the magnetic sheets increases, one end of the corresponding perforated plate can be raised, and when the number decreases, one end of the corresponding perforated plate can be lowered. A second horizontal bubble tube is used to adjust the level of the corresponding perforated plate.

[0012] A step pin is inserted into the step hole, and the lower end of the step pin extends downward out of the step hole. The diameter of the lower end matches the inner diameter of the first hole. After being inserted into the first hole along the step hole, the step hole and the first hole are driven to be vertically aligned, so that the steel ruler plate can be quickly calibrated to the base point position.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a measuring device for heating boiler installation. When working, the step hole of a steel ruler plate is aligned with the first hole, and the steel ruler plate is straightened in the direction of a construction drawing and kept horizontal. Then, taking the step hole as a base point, two movable rulers are translated to designated positions along the horizontal scale on the steel ruler plate according to the parameters of the construction drawing. The two movable rulers are kept horizontal, and chalk is used to mark the lower edge of the steel ruler plate to measure the installation position of one of the steel rails. Then, the two perforated plates can be moved to the designated positions along the vertical scale to align with the two screw holes of the other steel rail, and a drill is used to vertically drill a hole to measure the installation position of the other steel rail. The installation measurements of the two steel rails are linked to each other, so that the installation positions of the two steel rails can be found and marked at one time, which is conducive to reducing the burden of positioning measurement.
