Description

Column Straightness Measurement Tool

technical field

The utility model belongs to the technical field of equipment manufacturing and measurement, and in particular relates to a straightness measurement tool for towers.

Background technique

When designing the tower, there are clear technical requirements for the straightness of the tower body, and the deviation of the straightness has a great impact on the strength, stability and safety of the tower. The traditional straightness measurement tools for towers include steel wire measurement, cotton thread measurement, etc., but these measurement methods have their own disadvantages. The steel wire will sag due to its own weight, while the cotton thread is difficult to pull into a straight line due to its elasticity, which will cause inaccurate measurement and affect the equipment. the accuracy of the test.

As a further preference of the present utility model, the fixing device is a suction cup. The suction cup is a strong suction cup that can meet different surface quality requirements.

As a further preference of the present invention, the laser emitter is fixed on the support. The laser transmitter is fixed on the support, which can realize the straightness measurement of the vertical tower.

As a further preference of the present utility model, the measuring tool is calibrated before use, the support and the scale are fixed on the same horizontal plane through a fixing device, and the vertical distance from the laser emitting point of the laser emitter to the tower to be measured is on the same level as the scale. The vertical distance from the laser projection point to the tower to be tested is equal.

As a further preference of the present utility model, a scale is provided on the support, and the lower end of the scale is flush with the bottom of the support. A scale is set on the support to facilitate further observation and adjustment, and to determine that the vertical distances from the laser emission point and the projection point to the tower to be measured are equal.

As a further preference of the present utility model, the laser emitter is an instrument including a laser emitting function. In order to realize the multiple utilization of on-site instruments, a laser rangefinder can be selected.

As a further preference of the present invention, the scale includes a clamp and a connecting rod; the clamp is used to fix the laser emitter, and the connecting rod supports the clamp. Preferably, a rotating shaft is provided on the connecting rod, so that the connecting rod can rotate 360°. To meet the adjustment needs of the laser transmitter.

As a further preference of the present utility model, the scale is embedded in the fixing device, so that the contact surface between the scale and the tower to be measured is a zero scale standard.

The straightness measuring tool of the tower vessel of the utility model can avoid the error caused by the defects of the steel wire or the cotton thread of the traditional measuring tool, and the laser transmitter is economical and convenient, flexible and simple to operate, and has high precision.

detailed description

Example 1

As shown in Figure 1, a kind of straightness measurement tool of tower comprises support 2, scale 3 and fixing device 4; Described support 2 and scale 3 are fixed on the tower device 5 to be measured by fixing device 4; Scale 3 Embedded in the fixture 4, so that the contact surface between the scale 3 and the tower to be measured 5 is a zero scale standard; as shown in Figure 2, the structure of the support 2 includes a clamp 21 and a connecting rod 22, and a rotating shaft is arranged on both banks so that the connecting rod 22 The 360° rotation can be realized; the laser emitter 1 is fixed on the fixture 21 , and the laser emitter 1 is placed facing the scale 3 , so that the laser projection point emitted by the laser emitter 1 falls on the scale 4 .

The measurement tool is calibrated before use, and the support 2 and the scale 3 are fixed on the same horizontal plane through the fixing device 4. The vertical distance from the laser emission point of the laser transmitter 1 to the tower to be measured 5 is the same as the laser projection point on the scale 3 to The vertical distances of the towers 5 to be tested are equal. Then place the tool on the tower to be tested and move it, measure the offset of the projection point at intervals, and finally calculate the straightness of the tower after counting the offsets.

The fixing device 4 selected in this embodiment is a suction cup.

The laser transmitter 1 in this embodiment is a laser rangefinder including a laser transmitter.

Example 2

The only difference between embodiment 2 and embodiment 1 is that a scale is also provided on the support, and the lower end of the scale is flush with the bottom of the support. It is convenient for further observation and adjustment, and it can be confirmed that the vertical distances from the laser emission point and the projection point to the tower to be tested are equal.
