Description

Measuring tape for measuring spatial position

Technical Field

The invention belongs to the technical field of measurement, relates to a measuring tape, and particularly relates to a measuring tape for measuring a spatial position, which can be used for measuring the length of a curve in a three-dimensional space.

Background

Measurement of spatial position has been an important issue in equipment installation. For example, in the connection of oil and gas pipelines of equipment components, due to the different spatial positions of the components, the oil and gas pipelines are prepared in actual operation, which is long or short, and the operation is time-consuming and labor-consuming, so that the operation efficiency is low. At present, the measuring tape on the market can not measure curves and curve distances in three-dimensional space, so that equipment capable of quickly and conveniently measuring the distances of oil and gas pipelines distributed in the three-dimensional space is urgently needed.

Disclosure of Invention

The invention aims to provide a measuring tape for space measurement, which solves the problem that curves in a three-dimensional space cannot be accurately measured in time.

In order to solve the technical problems, the invention adopts the technical scheme that:

a tape measure for spatial position measurement, characterized by: including casing, reel and gooseneck chi area, the reel passes through the revolute pair and installs at the casing middle part, and casing one side is equipped with the chi area export, and the gooseneck chi area winding forms the cake form on the reel, and the gooseneck chi outer end stretches out from the chi area export, the reel passes through drive arrangement drive rotation.

As an improvement, the driving device is a rocker arm, the rocker arm comprises a force arm and a crank, one end of the force arm is fixedly connected with a shaft of the winding drum, and the other end of the force arm is connected with the crank.

As an improvement, a clockwork spring is arranged in the shell and connected with the winding drum, and the winding drum automatically rotates through the clockwork spring.

As an improvement, the diameter of the gooseneck measuring tape is not more than 5 mm.

As an improvement, the shell is formed by fixedly connecting a shell A and a shell B through bolts.

The invention has the beneficial effects that:

the invention can realize the distance measurement in plane and three-dimensional space, can finish the space shaping of the measured pipeline or line, can finish the measurement of the length and angle of each part after shaping, can easily finish the work of early development and wiring of the pipeline and line gas circuit, and the like, has simple structure, is a pure mechanical structure, does not need electronic devices, has stable performance and is convenient to use.

Detailed Description

The invention will now be illustrated by way of example with reference to the accompanying drawings,

as shown in fig. 1 to 7, a tape measure for measuring spatial position comprises a shell, a winding drum and a gooseneck measuring tape, wherein the winding drum is arranged in the middle of the shell through a revolute pair, the winding drum can be arranged on the shell through a hole in clearance fit, the winding drum can also be arranged on the shell through a bearing, a measuring tape outlet is arranged on one side of the shell, the gooseneck measuring tape is wound on the winding drum to form a round cake shape, the outer end of the gooseneck measuring tape extends out of the measuring tape outlet, and the winding drum is driven to rotate through a driving device. The shell is formed by fixedly connecting a shell A and a shell B through bolts.

The driving device is a rocker arm, the rocker arm comprises a force arm and a crank, one end of the force arm is fixedly connected with the drum shaft through a bolt B, the other end of the force arm is fixedly connected with the crank shaft through a bolt C, the crank comprises a crank shaft and a handle, the handle can be freely rotated and sleeved on the crank shaft, and the handle is limited through a bolt D and prevented from falling off.

As a more preferred embodiment, a clockwork spring is arranged inside the shell and is connected with the winding drum, and the winding drum automatically rotates through the clockwork spring to retract and coil the gooseneck measuring tape on the winding drum.

As shown in fig. 8, the surface of the gooseneck measuring tape is provided with scales for reading, the scales on the surface of the gooseneck measuring tape deform along with the bending of the gooseneck measuring tape, but the actual reading position is located at the outlet of the oil-gas pipeline and is not bent generally as long as the reading position is kept in a non-bending state, in addition, the shape of the bent oil pipe can be shaped and marked at the outlet through the gooseneck measuring tape, and then the marking position can be measured and corrected more accurately by other tools after the gooseneck measuring tape is taken out.

As a more preferred embodiment, the gooseneck measuring tape has a diameter of no more than 5 mm.

As shown in fig. 9, the tape is fixed in such a way that the gooseneck tape is inserted into the radial small hole of the reel, the reel shaft is inserted into the small hole at the end of the gooseneck tape, the reel and the force arm are in key connection with the reel shaft, the two sides of the reel shaft are locked by the nut, and when the force arm rotates, the reel shaft and the reel can drive the gooseneck tape to rotate together, so that the gooseneck tape extends out or retracts. As shown in fig. 9.

The specific use method is basically the same as that of a common steel tape, the gooseneck measuring tape can be bent, screwed and the like according to actual needs after being pulled out, the measuring tape is shaped in space according to a track, an outline dimension or space wiring and the like to be measured, meanwhile, the measuring tape is read according to scales on the measuring tape, the measurement of angles and the like can be completed by other measuring instruments after the shaping, the measuring tape is suitable for the early-rise development wiring, measurement and other work of various pipeline gas circuits, and the measuring tape can be withdrawn through a crank after the measurement is finished.
