Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

As shown in fig. 1 and 2, the utility model relates to a municipal engineering cost field measurement tool, which comprises a connecting frame 1, wherein a clamping module 4, a circle run-out detection module 6 and a control module 2 are arranged on the connecting frame 1. The connecting frame 1 is provided with a carrying handle 26, which is convenient for carrying and measuring.

The clamping module 4 is used for clamping the outside of the pipeline, and the clamping module 4 comprises a double-shaft motor 15, and the double-shaft motor 15 is fixedly installed on the connecting frame 1. The output shafts at the two ends of the double-shaft motor 15 are respectively provided with a screw rod 16, and the two screw rods 16 are positioned on the same straight line. Both ends of the double-shaft motor 15 are provided with guide sleeves 18, and the two guide sleeves 18 are fixed on the connecting frame 1. The inside of uide bushing 18 all sliding connection has slide arm 17, and slide arm 17 and lead screw 16 one-to-one are provided with the screw hole in the one end inside of slide arm 17, and V type holder 5 is installed to the other end bending portion 3 department of slide arm 17, and the tip embedding of lead screw 16 is in the inside of screw hole, lead screw 16 and screw hole looks adaptation. When the double-shaft motor 15 drives the two screw rods 16 to synchronously rotate, the screw rods 16 drive the sliding arms 17 to linearly move under the action of the screw thread force, and the two sliding arms 17 simultaneously move in opposite directions or simultaneously move in opposite directions.

As shown in fig. 3, the V-shaped clamping member 5 includes a clamping frame 51, two roller mounting rods 52 are fixedly connected to the clamping frame 51, rollers 53 are mounted on the roller mounting rods 52, and the rollers 53 can convert original sliding friction into rolling friction when clamping a pipeline, so that damage to the pipeline is reduced. When the outside of the pipeline is clamped, the screw rod 16 is driven by the double-shaft motor 15 to rotate, so that the two sliding arms 17 are driven to move in opposite directions, the two V-shaped clamping pieces 5 are close to the pipeline, and when the V-shaped clamping pieces 5 clamp the outside of the pipeline, the rotation of the double-shaft motor 15 is stopped when the rotation resistance of the double-shaft motor 15 is larger than a set value, so that the clamping of the outside of the pipeline is realized.

The circle run-out detection module 6 comprises a motor 9, and the motor 9 is fixedly arranged on the connecting frame 1 through a motor frame 8. The output shaft of the motor 9 is connected with a circular rail transmission unit which comprises a gear 10, a gear ring 11, a circular rail 12 and an arc-shaped sliding rail sleeve 7. The arc-shaped slide rail sleeve 7 is fixedly arranged on the connecting frame 1, the gear 10 is arranged on an output shaft of the motor 9, the round slide rail 12 is fixed on the outer wall of the gear ring 11, the round slide rail 12 is embedded in the arc-shaped slide rail sleeve 7 in a sliding manner, and the gear 10 is meshed with the inner side of the gear ring 11. The gear ring 11 is provided with a spring telescopic rod 13, the spring telescopic rod 13 comprises a rod body, a rod sleeve and a spring, one end of the rod body is inserted into the rod sleeve in a sliding mode, the spring in the rod sleeve exerts elastic force on the rod body, the rod body stretches out of the rod sleeve to the maximum extent, and one end of the rod body points to the circle center of the gear ring 11. Before measurement, the distance from the tail end of the rod body (the end far away from the center of the circle of the gear ring 11) to the center of the circle of the gear ring 11 should be larger than the radius of the round tube to be measured, and during measurement, the inner wall of the round tube presses down the tail end of the rod body, and the pressing force is opposite to the elasticity of the spring. The linear displacement sensor is embedded in the rod sleeve, and the linear displacement sensor can sense the movement of the rod body.

Meanwhile, on the premise that the roundness of the outer circle of the circular tube is qualified (because the roundness of the outer circle of the circular tube is usually detected strictly during municipal purchasing, when the interior of the circular tube is detected, no external circle is required to be detected, and the standard circle is defaulted), the orthographic projection of the midpoint of the connecting line between the two V-shaped clamping pieces 5 on the plane of the gear ring 11 is positioned at the circle center of the gear ring 11, and because the two V-shaped clamping pieces 5 are symmetrically arranged and the moving distance is consistent all the time, after the circular tube is clamped firmly by the clamping module 4, the circle center of the gear ring 11 is positioned on the central axis of the circular tube, and therefore, the clamping module 4 is used for positioning the circle center of the gear ring 11 at the central axis of the circular tube, so that the circle runout data of the inner wall of the circular tube can be measured conveniently. The arrangement of the gear ring 11 and the gear 10 plays a role in reducing the speed, so that the rotation speed of the spring telescopic rod 13 is not too high.

When the circular runout detection module 6 is inserted into a pipeline during measurement, after the clamping module 4 clamps a circular tube firmly, the motor 9 drives the gear 10 to rotate, so that the gear ring 11 is driven to rotate, the spring telescopic rod 13 and the gear ring rotate synchronously, the tail end of the rod body is always abutted against the inner diameter of the circular tube under the action of spring force in the rotating process of the spring telescopic rod 13, the tail end of the rod body is in sliding connection in the rotating process, the friction resistance can be effectively reduced, and if the inner wall circle of the cross section of the circular tube is a standard circle, the position of the rod body relative to the linear displacement sensor is unchanged in the rotating process; if the inner wall circle of the cross section of the circular tube is unqualified, the position of the rod body relative to the linear displacement sensor can change and fluctuate in the rotation process, the fluctuation is larger as the roundness of the inner wall circle of the cross section of the circular tube is worse, and the judgment can be carried out according to the position change information output curve received by the linear displacement sensor. In addition, the control module comprises operating buttons for controlling the biaxial motor 15 and the motor 9.
