Abstract
The invention discloses an expansion joint tension tester which comprises a fixed working platform; a screw rod is arranged on the fixed working platform; the two ends of the screw rod are respectively connected with a nut; the nuts are arranged on a cross beam in a sliding way; a chain wheel is arranged in the middle of the screw rod; the chain wheel is connected with a speed reducing motor arranged on the fixed working platform; the rotation of the screw rod is transformed into the linear motion of the nuts; the nuts are respectively connected with the two ends of an expansion joint by a fixture; a tension sensor is arranged between each fixture and each nut. The expansion joint tension tester is simple in test working procedures and convenient to operate, and also is capable of rapidly and accurately detecting and recording the test results and is accurate in test data and high in detection precision, thus completely meeting the requirements of detecting and testing the expansion joints which are produced on a large scale.
Description
Technical field
The present invention relates to a kind of tension tester, specifically a kind of expansion pipe tension tester.
Background technology
Along with developing rapidly of track traffic, more and more higher to the quality requirements of track Traffic Steel aluminum composite contact rail.Expansion pipe is as the vitals of steel-aluminum conductor rail, its quality directly has influence on the quality of whole track traffic steel-aluminum conductor rail, and expansion pipe initial sliding power is one of important performance indexes of weighing expansion pipe quality, up to the present, there is no ripe equipment in order to test expansion pipe initial sliding power, and common apparatus can not meet the requirement of producing expansion pipe detection and test in enormous quantities.
Summary of the invention
The object of this invention is to provide a kind of expansion pipe tension tester, not only test step is simple, easy to operate to use this equipment, and can also detect quickly and accurately, logging test results, detection data are accurate, accuracy of detection is high, can meet produce the requirement that expansion pipe detects and tests in enormous quantities completely.
Object of the present invention is achieved through the following technical solutions:
A kind of expansion pipe tension tester, is characterized in that: this testing machine comprises stationary work-table, on stationary work-table, be provided with screw rod, the two ends of screw rod are connected with nut, and nut is slidably disposed on crossbeam; Middle part at screw rod is provided with sprocket wheel, and sprocket wheel is connected with the reducing motor being arranged on stationary work-table; And the rotation of screw rod is converted to the rectilinear motion of nut; Nut is connected with the two ends of expansion pipe by fixture; Between fixture and nut, be provided with pulling force sensor.
In the present invention, on crossbeam, be provided with the travel switch that length while preventing from exceeding travel range when expansion pipe from pulling open and pulling back is less than minimum length.Reducing motor is arranged on the lower shoe of stationary work-table.Described crossbeam can be unequal angle.
Reducing motor by chain-driving sprocket wheel and make nut and screw rod between relatively move.On stationary work-table, be provided with bearing seat, the two ends of screw rod are connected with nut respectively after being arranged on the bearing in bearing seat.
In the present invention, be provided with line slideway on crossbeam, nut is slidably disposed on line slideway.Described crossbeam is unequal angle.Stationary work-table is carrying a whole set of equipment, and reducing motor is as drive part, and nut is connected to and in expansion pipe, is pulled open expansion pipe left and right slide block by fixture.
First the present invention utilizes reducing motor and chain-wheel mechanism to realize relatively moving between nut and screw rod, next arranges sensor and accurately judges the size of pulling force, between expansion pipe and fixture, utilize the middle hole of aluminium rail to locate, not only simple in structure, and also also high to the accuracy of measurement of pulling force.Last expansion pipe is provided with travel switch, and when preventing from exceeding when expansion pipe from pulling open travel range and pulling back, length is less than minimum length.
The present invention has not only reduced workman's labour intensity and working time, and has improved precision and speed that pulling force detects, can reach the object that realizes fast detecting, adapts to the needs of mass production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the scheme of installation of fixture and pulling force sensor in the present invention.
Embodiment
A kind of expansion pipe tension tester, is shown in Fig. 1 and Fig. 2, and this testing machine comprises stationary work-table 21, is provided with screw rod 12 on stationary work-table, and the two ends of screw rod are connected with nut 5, and nut is slidably disposed on crossbeam 1; Crossbeam is unequal angle.On crossbeam 1, be provided with line slideway 7, nut is slidably disposed on line slideway.On stationary work-table, be provided with bearing seat 13, the two ends of screw rod are sleeved on nut respectively after being arranged on the bearing in bearing seat.Nut 5 is fixed on slide block 22 by bolt 2 and web joint 4, and slide block is arranged on line slideway and can horizontally slips along line slideway.The middle part of screw rod is provided with sprocket wheel 9, and sprocket wheel 9 is connected with the reducing motor 17 being arranged on stationary work-table, and converts the rotation of screw rod 12 rectilinear motion of nut 5 on line slideway to.Reducing motor is arranged on the lower shoe of stationary work-table.Nut 5 is connected with the two ends of expansion pipe 6 by fixture 30; Between fixture and nut 5, be provided with pulling force sensor 25.Pulling force sensor one end is connected on nut by bolt 24, and the other end is by bolt 26 jockeies, and travel range is 0-500kg.
On the opposite side crossbeam relative with pulling force sensor, be provided with the travel switch 11 that length when exceeding travel range while preventing that expansion pipe from pulling open and pulling back is less than minimum length, be respectively 710mm and 820mm apart from the distance of center line.
Process of the test of the present invention is as follows:
When test, expansion pipe is placed in and table is installed above, and the thru-bolt of fixture inserts in the hole of expansion pipe, then starter motor, slowly pull open expansion pipe, read the data of the handset being connected with sensor simultaneously, and record, while pulling open terminal, motor reversal, the left and right slide block of expansion pipe is toward pulling back, and reading out data, judges according to above-mentioned two secondary data whether the initial sliding force of expansion pipe meets the demands simultaneously.
