Description
Technical Field
The utility model relates to a bridge pipe compensator measuring tool.
Background
In the laying process of the gas pipeline, a compensator is required to be arranged between the two pipelines so as to compensate expansion and contraction caused by temperature change of the pipeline and prevent the pipeline from cracking caused by thermal stress generated by expansion and contraction caused by contraction. In daily maintenance, the compensator is often subjected to length measurement so as to judge whether the expansion amount of the compensator is within an allowable range, ensure the normal work of the compensator and judge whether a pipeline is in a normal running state through the length change of the compensator. However, the existing measuring tool can only read the measured length change data of the compensator from a long distance, and cannot read the data from a short distance, so that the accuracy of the measured data is difficult to guarantee, and the measuring requirements of compensators of different models cannot be met.

The to-be-solved technical problem of the utility model is: in order to overcome not enough among the prior art, the utility model provides a bridge pipe compensator measuring tool to through changing the data reading mode, improve the accuracy of data, and satisfy the measurement requirement of different model compensators.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a bridge pipe compensator measuring tool, includes the telescopic link, telescopic link upper end articulated have the measuring stick that has the scale for a pair of mark of telescopic link bilateral symmetry distribution, it has the vaulting pole of synchronous shrink or open a pair of measuring stick to articulate between measuring stick and the telescopic link, the spout has been seted up on the measuring stick, is equipped with in the spout of measuring stick tip and decides the pointer, and it decides the pointer that moves of pointer measurement compensator length to slide in the spout to be equipped with the cooperation.
Specifically, the top end of the telescopic rod is provided with external threads, the telescopic rod is provided with a bearing, two sides of the outer ring of the bearing are respectively hinged with the support rods, and the inner ring of the bearing is provided with internal threads which are connected with the external threads when the bearing moves upwards to open the pair of measuring rods.
A movable space is provided for a given pointer, the given pointer can be conveniently inserted into a compensator flange gap during measurement, and a spring which is elastically pressed on the side face of the fixed pointer is installed in a sliding groove between the end part of the measuring rod and the fixed pointer.
The bottom end of the telescopic rod is provided with an anti-skidding holding rod which is convenient to operate and hold.
The utility model has the advantages that: the utility model discloses a moving the pointer and removing along the spout, pointer measurement compensator length value is decided in the cooperation, has realized closely data reading, has guaranteed measured data's accuracy, also can satisfy the measurement requirement of different model compensators simultaneously.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the usage state of the present invention.
In the figure: 1. the measuring instrument comprises a telescopic rod, 2 measuring rods, 3 supporting rods, 4 sliding grooves, 5 fixed pointers, 6 movable pointers, 7 bearings, 8 springs and 9 anti-skidding holding rods.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in figures 1 and 2, the bridge pipe compensator measuring tool comprises a telescopic rod 1 formed by sleeving two sections of sleeves, the lower end of an upper sleeve of the telescopic rod 1 is in threaded connection with a lower sleeve of the telescopic rod 1, and an anti-skidding holding rod 9 convenient for operation and grasping is arranged at the bottom end of the lower sleeve of the telescopic rod 1.
Telescopic rod 1 goes up sheathed tube top and has the external screw thread, it has a pair of measuring stick 2 that marks the scale for 1 both sides symmetric distribution of telescopic rod to go up the sheathed tube top and articulate, installs bearing 7 on the telescopic rod 1 on the sleeve pipe, bearing 7 inner circle length is greater than the outer lane, and bearing 7 outer lane both sides articulate respectively has vaulting pole 3, the vaulting pole 3 other end with measuring stick 2 is articulated, the bearing 7 inner circle have with the internal thread that external screw thread fit connects, the diameter of the threaded diameter of bearing 7 inner circle is slightly greater than the diameter of 1 unthreaded department of telescopic rod, when bearing 7 reciprocates along the sleeve pipe on telescopic rod 1, promotes a pair of measuring stick 2 through vaulting pole 3 and opens or the shrink in step, when bearing 7 removed external screw thread department, through the cooperation of interior external thread connection, can make a pair of measuring stick 2 be in.
The measuring rod 2 is provided with a sliding groove 4, a fixed pointer 5 is arranged in the sliding groove 4 at the end part of the measuring rod 2, a movable pointer 6 matched with the fixed pointer 5 to measure the length of the compensator is arranged in the sliding groove 4 in a sliding mode, the length of the fixed pointer 6 is slightly larger than that of the fixed pointer 5, and one or more movable pointers 6 can be arranged according to needs.
A spring 8 elastically pressed on the side surface of the fixed pointer 5 is arranged in the sliding groove 4 between the end part of the measuring rod 2 and the fixed pointer 5, so that whether the fixed pointer 5 is in a state of returning to 0 or not can be fixed and detected, and if a measurer feels that force given by the spring 8 exists on hands, the state of returning to 0 is not achieved.
And gaskets are arranged on two sides of the spring 8 to prevent dislocation, and a rotary cover which is propped against the outer end of the spring 8 is connected to the outer end of the measuring rod 2.
During measurement, the bearing 7 is pushed to move upwards, the pair of measuring rods 2 is unfolded to keep a horizontal state, the movable pointer 6 is inserted into a flange of the compensator, then the movable pointer 6 moves rightwards along the sliding groove 4, when the movable pointer 6 moves to the position where the fixed pointer 5 can be inserted into two flanges of the compensator, the fixed pointer 5 is inserted for length measurement, and the length value of the compensator is read according to the scale value corresponding to the movable pointer 6 after the length measurement is finished.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
