Abstract
The utility model relates to a special tensioning clamp for measuring the resistance of a conductor, which comprises a base 9. A motor 1 and a speed reducer 3 are arranged on the base and driven by a belt 2. A rotating clamping head 4 is mounted on the output shaft of the speed reducer; and a fixed clamping head 6 is arranged at the other end of the base. The clamping head bodies 8 of the rotating clamping head and the fixed clamping head are cylindrical and are provided with quadrate hole slots vertical to the axial direction, and lock tongue blocks 7 are arranged in the hole slots and are mounted on the clamping head bodies through pin shafts. When the resistance of the conductor is measured by using the tensioning clamp, one end of the conductor is inserted in the fixed clamping head, and the other end thereof is inserted in the rotating clamping head on the output shaft of the speed reducer, and then the motor is started to drive the rotating clamping head to rotate, so as to straighten and tension the conductor; and then the resistance value of the conductor on a certain length can be measured by utilizing resistance measuring instrument. Because the conductor is tensioned, the measured value is accurate and reliable; and in addition, the special tensioning clamp has the positive effects of convenient use and accurate detection.
Description
Technical field
The utility model relates to a kind of attached apparatus of measurement mechanism, particularly belongs to a kind of stress accommodation that is used to measure conductor resistance.
Background technology
For guaranteeing engineering construction quality, need carry out necessary detection to employed starting material, wherein, the resistance detection that the employed leads of engineering such as electric power, communication, lightening protection installation are carried out on the unit length is exactly an important job.At present, for the existing specialized instrument of the resistance measurement of lead, its advanced technology, precision is higher.But, owing to there is not special-purpose lead stress accommodation, length and physical length that lead records because of crooked and distortion cause exist than mistake, also correspondingly there is error in the resistance of the unit length upper conductor that calculates based on this, thereby has influenced the fairness of testing result to a great extent.
Summary of the invention
The purpose of this utility model promptly is to provide a kind of novel conductor resistance to measure special-purpose stress accommodation, with quickly and easily with the stretching tensioning of detected lead, thereby guarantee the numerical value record purpose accurately and reliably.
Conductor resistance provided by the utility model is measured special-purpose stress accommodation, has base, base is provided with motor and speed reducer, utilize belt gear between the two, it is characterized in that, on the output shaft of reductor rotary chuck is installed, correspondingly, the other end on base, other has a fixed chuck; The above-mentioned rotary chuck and the collet body of fixed chuck are cylindric, and square hole slot perpendicular to axial direction is arranged, and wherein place latch bolt block; Described latch bolt block is installed on the collet body by bearing pin, and after the installation, the gap that forms between the square hole slot of latch bolt block and collet body promptly is used for the end of the detected lead of clamping.
When using the utility model to carry out the conductor resistance measurement, at first the end with detected lead inserts fixed chuck, the other end inserts the rotary chuck on the speed reducer output shaft, the starter motor running, the driven rotary chuck rotates, can be with the stretching tensioning of lead, utilize the resistance measurement instrument can record resistance value on this lead certain-length then.Because lead is tensioning, thus record numerical value accurately and reliably, have easy to use, detect good effect accurately.
Description of drawings
Accompanying drawing partly discloses specific embodiment of the utility model, is further described below in conjunction with accompanying drawing:
Fig. 1, the utility model general assembly structural representation;
Fig. 2, A-A is to view.
Embodiment
As shown in Figure 1, conductor resistance provided by the utility model is measured special-purpose stress accommodation, has base 9, and base 9 is provided with motor 1 and reductor 3, utilizes belt 2 transmissions between the two.Certainly, also can adopt other kinds of drive such as gear drive, chain drive between motor and the reductor, its effect is the same.Rotary chuck 4 is installed on the output shaft of reductor, can rotates together thereupon.At the other end of base 9, other has a fixed chuck 6, is complementary with rotary chuck 4, respectively clamping is implemented at the two ends of lead 5.
As shown in Figure 2, above-mentioned rotary chuck 4 is identical with the structure of fixed chuck 6, constitutes by collet body 8 and latch bolt block wherein 7.Collet body 8 is cylindrical, central part has square hole slot perpendicular to axial direction, wherein place latch bolt block 7, latch bolt block 7 is installed on the collet body by a bearing pin, after the installation, latch bolt block can be swung in the square hole slot of collet body, and the gap of Xing Chenging promptly is used for the end of the detected lead 5 of clamping between the two.Obviously, the end of lead 5 should be inserted the outside of rotary chuck 4 and fixed chuck 6 latch bolt blocks in use respectively, be about to lead and stride across the upper side of latch bolt block, and extend bearing pin with upper/lower positions.Because latch bolt block has the effect of lever, so when its upside bears the tension force of lead tension, its downside then tightly blocks lead, and, the pulling force of lead is big more, latch bolt block is just big more to the clamping force of lead, blocks just firmly more, therefore the utlity model has easy to use, clamping reliable characteristics.
