As shown in fig. 1-7, the present utility model provides a device for rapidly measuring a segment joint width, which comprises one or more measuring scales, wherein any measuring scale comprises:

The gradient type feeler gauge comprises a basic part 1 which is of a rectangular structure; the measuring part 2 is of a right-angle wedge-shaped structure, a right angle edge at the wide end of the measuring part is arranged along the width direction of the base part and is in fit connection with the short side of the measuring part, and the right angle edge between the wide end and the narrow end of the measuring part 2 is arranged along the length direction of the base part 1 and is parallel to the long side of the measuring part;

In the initial state, the movable cushion block 4 is located at the outer end part of the sliding rail 3 and aligned with the sliding rail, that is, the movable cushion block 4, the sliding rail 3 and the outer end part of the measuring part 2 are located on the same plane, so that when the movable cushion block 4 moves along the sliding rail 3 under the external acting force in the measuring state, the real-time displacement distance of the movable cushion block 4 can represent the relative movement distance of the outer end part (narrow end) of the measuring part 2. When the quick measuring device for the segment joint width is used for measuring the segment joint width, a measurer can hold the (outer end part of the) foundation part 1 by hand, aim the tip end (the narrow end of the measuring part) of the gradient feeler gauge at the segment joint gap, then clamp the movable cushion block 4 at the edge of the segment outside the joint gap, push the feeler gauge end to extend into the joint gap, and in the process, the right-angle edge between the narrow end of the measuring part and the wide end is always clung to the segment inner end face close to one side of the movable cushion block until the wide end of the measuring part 2 is clamped in the joint gap (namely, the hypotenuse of the measuring part is moved to be abutted to the segment inner end face on the other side), and cannot move to the depth continuously, and at the moment, the displacement distance of the movable cushion block 4 relative to the base 5 is the depth of the measuring part 2 extending into the joint gap.

In addition, for the condition that the size of the duct piece joint is larger (wider), the measuring part can also be arranged into a right trapezoid structure, namely, the outer end part (initial position) of the measuring part is widened, the narrow end of the measuring part is the upper bottom of the right trapezoid, and the wide end is the lower bottom and is in fit connection with the short side of the foundation part to form a whole. The displacement sensor can measure the relative displacement between the movable cushion block and the base in real time and transmit data to the display for processing, and can be arranged as a linear displacement sensor arranged between the base and the movable cushion block; in this embodiment, the displacement sensor is configured as a laser rangefinder fixed to the base for reading the real-time relative displacement of the movable pad. The display is internally provided with a control module (such as a microcontroller), the conversion of the movable cushion block displacement (the depth of the measuring part extending into the seam gap) -the segment seam width value (the width of the clamping joint of the measuring part and the inner end surfaces of the segments on two sides) is carried out through an operation unit, and the conversion principle is as follows: when the measuring part is in a right triangle structure, w=tanα×l, wherein W is the segment joint width, L is the displacement distance of the movable cushion block, and α is the included angle of the narrow end (right angle side and oblique side) of the measuring part; when the measuring part is in a right trapezoid structure, w=l ₀ +tan α is equal to L, wherein W is the segment joint width, L is the displacement distance of the movable cushion block, L ₀ is the length of the upper bottom of the trapezoid, and α is the included angle (acute angle) between the right-angle side and the trapezoid bevel side of the measuring part between the wide end and the narrow end.

Therefore, before measurement starts or after measurement is completed (under the condition that the measuring device does not extend into the seam), the movable cushion block can be automatically positioned at an initial position (initial state) under the action of the first compression spring, so that the movable cushion block is facilitated to be automatically reset after measurement is completed (the measuring ruler leaves the seam), and the phenomenon that the movable cushion block excessively moves in the process of pushing the measuring part to extend into the seam in a pushing manner is avoided, and the accuracy of measurement reading is influenced.

In another technical scheme, the segment joint width rapid measuring device is characterized in that the inner end of the sliding rail 3 is located on the base part 1, and the length of the sliding rail 3 overlapped with the base part 1 is not greater than the length of the movable cushion block 4.

When a plurality of measuring scales are installed in parallel by using a measuring rod and are measured, the positions and the directions of the measuring rods are adjusted to enable the measuring scales to be respectively aligned with the pipe piece seam to be measured, a plurality of measuring parts are synchronously pushed into the seam by a handle after a movable cushion block is clamped, the measuring parts cannot continuously stretch into the seam with smaller width after a certain distance is moved, at the moment, the handle is continuously pushed, the measuring parts in the seam with larger width can continuously move inwards, and a sliding mechanism on the measuring scale corresponding to the seam with smaller width performs compensation movement under the action of external pressure (additional pushing force of the handle), namely, a sliding rod replaces the measuring parts to move to the depth of the seam, so that the position of the whole measuring scale on the measuring rod is kept balanced, and other measuring scales are allowed to continuously and normally push into the seam for measuring. The multiple measuring scales mounted on the same measuring rod are generally used for measuring the widths of the joints at different positions on the same arc-shaped duct piece, a measurer can complete pushing actions of the multiple measuring scales at one time, after the handle cannot be pushed continuously, readings displayed on the measuring scales are sequentially read, simultaneous measurement of the widths of the joints of the multiple point positions can be achieved, manual workload is further reduced, measuring efficiency is improved, and construction managers can evaluate and refer to the width parameters at different positions in the same joint, so that the quality condition of the whole joint is judged rapidly.
