Description

Technical Field

[0001] The utility model relates to the field of measuring tools, in particular to a measuring tool for bent pipes. Background Art

[0002] Hydraulic transmission uses liquid as the working medium and utilizes the pressure energy of the liquid to transmit power. A complete hydraulic system consists of five parts, namely, energy device, actuator, control and adjustment device, auxiliary device, and liquid medium. Hydraulics are widely used in industry and civil industries due to its large power transmission, easy transmission and configuration. The function of the actuators (hydraulic cylinders and hydraulic motors) of the hydraulic system is to convert the pressure energy of the liquid into mechanical energy, thereby obtaining the required linear reciprocating motion or rotary motion. The function of the energy device (hydraulic pump) of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid.

[0003] At present, the hydraulic systems of presses, CNC machine tools, and casting and cutting equipment often require a large number of pipelines, and some pipelines need to be connected by elbows. The distances between the two joints of different pipelines in the horizontal and vertical directions are different, and the sizes of the required elbows are also different. When installing the elbow, it is necessary to measure the distances between the two joints in the horizontal and vertical directions so as to plan the shape of the elbow. However, this measurement method lacks physical markings, and the measurement is difficult. It often takes multiple measurements to make the elbow, and the measurement efficiency is low. At the same time, the hydraulic system pipeline design is generally high, and there are safety hazards during the measurement process.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problems of difficult measurement and low measurement efficiency in the prior art when measuring bent pipes, the utility model provides a measuring tool for bent pipes. The measuring tool for bent pipes comprises: a right-angle bracket, comprising a first arm and a second arm connected to the first arm; a measuring tube, comprising a first hard tube extending along the length direction of the first arm, and a second hard tube extending along the length direction of the second arm; the first hard tube forms a sliding connection with the first arm, and the second hard tube forms a sliding connection with the second arm; a ferrule suitable for connecting to a hydraulic pipeline is provided at one end of the first hard tube and the second hard tube away from the right-angle bracket.

[0006] The utility model includes a measuring tool for a bent pipe, which includes a right-angle bracket and a measuring tube. The right-angle bracket includes a first arm and a second arm for installing the measuring tube. The measuring tube includes a first hard tube and a second hard tube, wherein the first hard tube is slidably mounted on the first arm, and the second hard tube is slidably mounted on the second arm. When measuring the bent pipe, the end of the first hard tube away from the right-angle bracket is connected to the joint of the hydraulic pipeline through a ferrule, and the end of the second hard tube away from the right-angle bracket is connected to another joint of the hydraulic pipeline through a ferrule. At this time, it is only necessary to measure the length of the first hard tube extending out of the first arm and the length of the second hard tube extending out of the second arm to obtain the horizontal and vertical dimensions of the bent pipe. The vertical length dimension of the bent pipe is the sum of the length of the first hard tube extending out of the first arm and the length of the first arm, and the horizontal length dimension of the bent pipe is the sum of the length of the second hard tube extending out of the second arm and the length of the second arm, so that the bent pipe can be made more conveniently without measuring the bending dimension of the bent pipe.
