Abstract
Description
Technical Field
[0001] This utility model belongs to the field of Beckman beam deflection detection technology, specifically relating to a Beckman beam probe auxiliary positioning device. Background Technology
[0002] In my country's engineering construction field, the deflection index of roadbed and pavement is particularly important. The Beckman beam method is the most widely used method for deflection testing. The specification requires that the Beckman beam probe should be placed 3-5cm in front of the center point of the wheel gap of the test vehicle. Currently, when placing the Beckman beam probe in the wheel gap of the test vehicle, it is often done by visual inspection. This can only ensure that the probe is in the center of the wheel gap and does not contact the tire, but cannot ensure that the probe is 3-5cm in front of the center point of the wheel gap. This leads to most test data being distorted and not accurately reflecting the actual deflection, which is not conducive to the control of project quality. The main reason for this is the inaccurate placement of the probe during testing. This patent solves this problem very well. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a Beckman beam probe auxiliary positioning device that addresses the shortcomings of the prior art. It is applicable to all Beckman beams currently on the market and features simple structure, convenient use, and accurate positioning.
[0004] The Beckman beam probe auxiliary positioning device of this utility model includes: a base (2), a clamp (3), a marker block (4), a telescopic rod (5), and a crossbar (6). The base (2) is installed on the Beckman beam and can move back and forth relative to the Beckman beam. The clamp (3) is used to fix the base (2). The marker block (4) is connected to the side of the base (2) to assist in positioning the base (2) on the beam. The telescopic rod (5) is connected to the base (2) and can extend and retract relative to the base (2). The crossbar (6) is vertically connected to the top of the telescopic rod (5), and the front edge of the crossbar (6) and the front edge of the marker block (4) are on the same vertical plane.
[0005] The usage process and principle of this utility model:
[0006] To measure the radius of the rear tire of the test vehicle, first make a mark on the tire and the ground at the contact point. Direct the vehicle to move forward slowly in a straight line until the rear wheel rotates one full turn, and the mark on the tire (one full turn) is exactly at the tire contact point. Make a mark at the corresponding position on the ground. Measure the straight-line distance between the two marks on the ground, which is the tire circumference L, and calculate the tire radius r.
[0007] Install the positioning device on the front end of the assembled Beckman beam and move it so that the marker block is located at a distance of tire radius r + (3~5cm) from the probe and tighten the clamp.
[0008] Pull out the telescopic rod and insert the Beckman beam probe into the center of the wheel gap. Adjust the height of the telescopic rod so that the crossbar just touches the outermost edge of the tire. At this time, the probe is located 3-5cm in front of the center point of the wheel gap.
[0009] Once the telescopic pole is retracted, subsequent testing can be carried out according to relevant specifications.
[0010] The beneficial effects of this utility model are:
[0011] This invention can assist in the effective positioning of the Benkelman beam probe in the deflection detection of the Benkelman beam, solving the problem of inaccurate probe placement leading to distorted test data that cannot accurately reflect the actual deflection problem, thus helping to control and improve the quality of the project.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] Please see Figures 1 to 3 This utility model proposes an auxiliary positioning device for a Beckman beam probe, including a base (2), a clamp (3), a marker block (4), a telescopic rod (5), and a crossbar (6). The base (2) is installed on the Beckman beam and can move back and forth relative to the Beckman beam. The clamp (3) is used to fix the base (2). The marker block (4) is connected to the side of the base (2) to assist in positioning the base on the beam. The telescopic rod (5) is connected to the base (2) and can extend and retract relative to the base (2). The crossbar (6) is vertically connected to the top of the telescopic rod (5), and the front edge of the crossbar (6) is on the same vertical plane as the front edge of the marker block (4).
[0018] The usage process of this utility model is as follows:
[0019] 1. Measure the radius of the rear tire of the test vehicle. First, make a mark on the tire and the ground at the contact point. Direct the vehicle to move forward slowly in a straight line so that the rear wheel rotates one revolution and the mark on the tire (one revolution) is exactly at the tire contact point. Make a mark at the corresponding position on the ground. Measure the straight-line distance between the two mark points on the ground, which is the tire circumference L. Calculate the tire radius r.
[0020] 2. Install the positioning device on the front end of the assembled Beckman beam and move it so that the target block is located at a distance of r + (3~5cm) from the measuring head and tighten the clamp.
[0021] 3. Pull out the telescopic rod and insert the Beckman beam probe into the center of the wheel gap. Adjust the height of the telescopic rod so that the crossbar just touches the outermost edge of the tire. At this time, the probe is located in front of the center point of the wheel gap (3-5cm).
[0022] 4. Once the telescopic pole is retracted, subsequent testing can be carried out according to relevant specifications.
