Description

Technical Field

[0001] The utility model belongs to the field of petrochemical instruments, and in particular relates to a compressor probe installation tool. Background Art

[0002] The installation of compressor probe instruments has always been a tedious, difficult, and precise task. Main installation steps: Before inserting the probe into the installation hole, ensure that there is no debris in the hole and the probe can rotate freely without getting tangled with the wire.

[0003] The main difficulty in installing the displacement probe sensor is to calculate the zero-limit voltage of the installation, that is, the V value. The installation displacement involves the leakage value of the rotor being measured.

[0004] Here are two installation methods:

[0005] A simple installation method is to let the mechanical personnel use a micrometer as a measuring tool to pry the shaft to the 1 / 2 position, that is, the zero position, and then we install the probe to the voltage value of V=10V. This method has limited accuracy and is only suitable for compressors with smaller rotors.

[0006] The other is that mechanical personnel operate the probe instrument for concealed installation. The probe instrument has high detection accuracy requirements, and the detection principle and position are very special. Therefore, during the installation process, it is common to encounter small installation space, inability to tighten with common tools, and inability to achieve the required accuracy.

[0007] Therefore, we design a compressor probe installation tool to solve the above problems. Utility Model Content

[0008] In view of the problems that the installation space is small, common tools cannot be used to tighten the probe, and the required accuracy cannot be achieved during the installation of the probe, the utility model provides a compressor probe installation tool.

[0009] The utility model solves the technical problem by adopting a solution: a compressor probe installation tool, comprising a lower sleeve, an upper sleeve, a universal flexible shaft and a nut, wherein the interior of the lower sleeve and the upper sleeve are both hollow and both ends are open, and the lower sleeve is rotatably connected to the opposite ends of the upper sleeve;

[0010] An L-shaped clamp is fixedly installed at the bottom of the lower sleeve;

[0011] The nut is fixedly installed at the bottom open end of the lower sleeve, and the inner thread of the nut is connected with a threaded rod, and a clamping cavity is formed between the outer end of the threaded rod and the L-shaped clamp;

[0012] The universal flexible shaft is arranged in the lower sleeve and the upper sleeve, the lower end of the universal flexible shaft is fixedly connected with the threaded rod, and the upper end of the universal flexible shaft extends out of the upper sleeve.

[0013] Preferably, two hinged parts are arranged on the top of the lower sleeve, and two hinged blocks are fixedly connected to the bottom of the upper sleeve, and adjacent hinged parts and hinged blocks are hinged via pins.

[0014] Preferably, a pressing plate is fixedly connected to the outer end of the threaded rod.

[0015] Preferably, the upper section of the upper sleeve is sleeved with a rubber sleeve.

[0016] Preferably, a rotating disk is fixedly mounted on the upper end of the universal flexible shaft.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the rotation of the threaded rod by rotating the universal flexible shaft, so that the threaded rod is screwed out of the lower sleeve, and then the bolt at the tail of the probe is clamped and fixed by the cooperation of the threaded rod and the L-shaped clamp. On the one hand, there is no need for workers to hold and stabilize the position of the probe in a narrow space. On the other hand, the tool can be directly used to rotate the probe to install the probe, and the lower sleeve and the upper sleeve can be rotated, which further facilitates the workers to use it in a narrow space, ensures the installation accuracy of the probe, and improves the work efficiency of the compressor probe installation.

[0019] 2. The utility model is provided with a universal flexible shaft, and when the upper sleeve rotates, the universal flexible shaft can bend adaptively, and at the same time, the universal flexible shaft can be used to drive the threaded rod to rotate at the upper end of the upper sleeve, so as to control the clamping or loosening of the probe, further facilitating the use of workers.
