Abstract
The utility model discloses a stress detection device of a bridge inhaul cable, which is characterized by comprising a first fixing ring, a fixing frame fixedly arranged on the first fixing ring, a second fixing ring, a baffle fixedly arranged on the second fixing ring and an infrared induction transmitter, wherein the first fixing ring is fixedly sleeved outside a first anchorage device positioned at the bottom of the inhaul cable; the advantage is through measuring the distance change between first ground tackle and the second ground tackle at every turn to obtain the elongation change of cable body, the stress state of real-time supervision cable judges whether the cable is the safe state, and this distance changes detection device simple structure, simple to operate, cost are lower, detection effect is better.
Description
Technical Field
The utility model belongs to the technical field of the atress detects and specifically relates to a stress detection device of bridge cable.
Background
The cable component of striding the bridge greatly is the main bearing member of bridge, be in the position of very key and core, the corruption of cable, the fracture, the atress is inhomogeneous etc, can bring huge potential safety hazard for the use of bridge, therefore, need regularly inspect the bridge cable, with the tensile change situation of aassessment cable, because the length of cable component often is longer, the change of bridge cable force in the operation process can lead to the length of cable to appear meticulous shortening or extension, current cable detection technique generally detects through the manual work, there is certain error, detection effect is relatively poor.
Disclosure of Invention
The utility model aims to solve the technical problem that a stress detection device of bridge cable is provided, not only simple structure, simple to operate, cost are lower, moreover can the stress state and the detection effect of real-time supervision cable better.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a atress detection device of bridge cable, includes first solid fixed ring, fixed setting and is in first solid fixed ring on mount, the solid fixed ring of second, fixed setting be in the solid fixed ring of second on baffle and infrared induction transmitter, the fixed cover of first fixed ring establish the outside at the first ground tackle that is located the bottom of cable, the fixed cover of second fixed ring establish the outside at the second ground tackle that is located the top of cable, infrared induction transmitter fixed set up the mount on, infrared induction transmitter's transmitting direction with the position of baffle correspond.
The mount include connecting plate, mounting panel and limit baffle, the connecting plate the top with first solid fixed ring's bottom fixed connection, the one end of mounting panel buckle fixed connection and be in the bottom of connecting plate, limit baffle's bottom buckle make progress fixed connection in the other end of mounting panel, the connecting plate on seted up the emission hole, infrared induction transmitter fixed setting be in limit baffle on, infrared induction transmitter's probe pass and upwards stretch out the emission hole. The simple structure, the cost of mount are lower, and it is convenient not only to install on first solid fixed ring, and it is also convenient that infrared induction transmitter installs on the mount moreover, and is better to the distance change detection effect between first ground tackle and the second ground tackle.
The first fixing ring and the second fixing ring are both of a hoop structure.
Compared with the prior art, the utility model has the advantages that the first fixed ring fixed sleeve is arranged outside the first anchorage device at the bottom of the inhaul cable, the second fixed ring fixed sleeve is arranged outside the second anchorage device at the top of the inhaul cable, the infrared induction transmitter is fixedly arranged on the fixed frame, the transmitting direction of the infrared induction transmitter corresponds to the position of the baffle, after the distance change detection device is arranged on the inhaul cable, the infrared rays transmitted by the infrared induction transmitter are shielded by the baffle to obtain the distance between the first anchorage device and the second anchorage device, and the distance change between the first anchorage device and the second anchorage device is obtained by each measurement, so that the elongation change of the inhaul cable body is obtained, the stress state of the inhaul cable is monitored in real time, whether the inhaul cable is in a safe state is judged, and the distance change detection device has simple structure, convenient installation, lower cost and better detection effect; but the relative displacement through monitoring cable both ends determines the cable force deflection of cable accurately, combines the initial pulling force data of cable when the bridge just built, can accurately conveniently assess out the cable force state during operation, utilize current measuring instrument with the utility model discloses correspond technical device and can determine the relative displacement at operation process middle period both ends accurately to realize the short-term test of cable force.
