Embodiment 1

[0032]Embodiment 1 includes a frame 1, the frame 1 includes a casing 101 and legs 102 arranged in a rectangular arrangement at the bottom of the casing 101, the frame 1 is provided with a first wheel 2, the first A second runner 3 is rotatably connected to the frame 1 below the runner 2, and steel strands can pass between the first runner 2 and the second runner 3. The first rotation 2 and the second runner 3 They are all arranged in the housing 101, and there is an elastic mechanism between the first runner 2 and the frame 1 so that the first runner 2 can move up and down and has a downward pressure. During use, the steel strand Enter from the entrance of the housing 101, and then enter between the first runner 2 and the second runner 3, the interval between the first runner 2 and the second runner 3 in the initial state is less than the diameter of the steel strand, And because the surface of the first runner 2 and the second runner 3 facing the entrance is an arc surface, w...

Embodiment 2

[0033] Embodiment 2, on the basis of Embodiment 1, the two ends of the first runner 2 are rotatably connected with a bearing seat 23 via a first rotating shaft 25, and the bearing seat 23 is vertically slidably connected to the frame 1. The upper end of the bearing seat 23 is connected with the second compression spring 24 whose other end is connected on the frame 1, constituting an elastic force device. Specifically, a first rotating shaft 25 is fixedly connected to both ends of the first rotating wheel 2, and a bearing housing 23 is rotationally connected to both ends of the first rotating shaft 25, and a plurality of sliding rods 26 are vertically slidingly connected in the bearing housing 23, and the sliding rods 26 The upper and lower ends of the upper and lower ends are respectively fixed on the frame 1, and the two ends of the slide bar 26 are respectively fixed on the second stage clip 24 at the upper end of the bearing on the frame 1. When the steel strand continuousl...

Embodiment 3

[0034] Embodiment 3, on the basis of Embodiment 2, the tensioning device of the belt 5 includes a sleeve 27 fixed on the frame 1, and the sleeve 27 is axially slidably connected with a movable rod 28, and the movable rod 28 free ends are connected with a base bar 29 perpendicular thereto, and the front and rear ends of the base bar 29 are respectively connected with vertical support bars 30, and also include a tension pulley 31 connected to the belt 5, the tension pulley The two ends of 31 are rotatably connected to two supporting rods 30 respectively, and a tension spring 44 sleeved on the movable rod 28 is connected between the sleeve 27 and the base rod 29 . The belt 5 tensioning device makes when the first pulley 4 follows the first runner 2 and jumps up and down, the belt 5 between the first pulley 4 and the second belt 6 is always stretched, and will not slip, which improves the measurement precision.

Abstract

The present invention provides a road and bridge construction measurement device. The problems are effectively solved that errors are large, labor intensity is high, the efficiency is low and economicbenefit is lost when manual length measurement is performed. The method provided by the invention reduces the consumption of raw materials, saves the labor and save the cost so as to improve the economic benefit. The method employs a mechanical structure to achieve measurement of the length of a steel strand with no need for electric energy so as to facilitate usage in the construction process, have convenient and accurate measurement and low worker labor intensity and be suitable for batch measurement of the steel strand, after the steel strand reaches a predetermined length, a runner can belocked and is not rotated, the length of the steel strand is a required length, and after the a structure on a graduated disc is set, the method can automatically obtain the steel strand with the required length.

Description

technical field [0001] The invention relates to the field of roads and bridges, in particular to a road and bridge construction measuring device. Background technique [0002] In recent years, with the continuous development of my country's economy, driven by key construction projects and large-scale projects, the technical level of prestressed concrete engineering in my country has been greatly improved. At present, prestressing technology has become a very important structural material and special process means in civil engineering in our country, and its application range is expanding day by day. In the prestressed concrete construction process of bridge engineering, high-strength and low-relaxation prestressed steel strands are basically used. In the process of using the steel strands, the steel strands need to be cut according to the specified length to obtain the required length. of steel strands. In the prior art, the length selection of steel strands is usually mea...
