Problems solved by technology
[0004] In order to make up for the deficiencies of the existing technology, the present invention proposes a composite laser ranging system, which solves the problem that the frozen ground tends to make the outriggers slip and affect the measurement accuracy, causing construction errors, resulting in delays in the construction period, increasing construction costs, and outriggers slipping. It is also easy to cause the rangefinder to fall, affecting the accuracy of the rangefinder and increasing the maintenance cost of the rangefinder

Embodiment approach
[0026] As an embodiment of the present invention, a spring 28 is fixedly connected to the inner bottom wall of the chute 22; during work, when the operator steps on the pedal 23 to the position of the spring 28, the spring 28 buffers the pedal 23 to prevent The operator did not retract the force in advance, causing the pedal 23 to be damaged, causing the operator to fall and be injured under the action of inertia, thereby improving the safety during the operation. When the operator releases the pedal 23, the pedal can be accelerated under the elastic force of the spring 28 The resetting of 23 reduces the resistance caused by the resetting of pedal 23 to counterweight 26 sliding downwards, thereby improving the knocking effect of counterweight 26 on fixing cone 27, and improving the fixing efficiency of fixing cone 27.
[0027] As an embodiment of the present invention, the cross-section of the fixing cone 27 is in the shape of a "cross"; during work, when inserted into the grou...

The invention belongs to the technical field of surveying and mapping, and particularly relates to a composite laser ranging system which comprises a laser range finder, a bracket and a supporting leg. A fixing mechanism is arranged on the supporting leg, and comprises a mounting groove, a sliding groove, a pedal, a fixed pulley, a steel wire rope, a balancing weight and a fixing cone; the mounting groove is formed in the bottom of the supporting leg; the sliding groove is formed in the outer edge of the supporting leg; the pedal us slidably connected to the interior of the sliding groove; the fixed pulley is rotatably connected to the inner top wall of the mounting groove, and the balancing weight is slidably connected to the interior of the mounting groove; the fixing cone is slidably connected to the position, below the balancing weight, in the mounting groove; and the top of the balancing weight is fixedly connected with one end of the steel wire rope. According to the composite laser ranging system, through arrangement of the fixing mechanism, the fixing effect of the range finder on frozen soil is improved, and the range finder is prevented from deviating; the range finding precision and the range finding efficiency are improved, and the construction cost is reduced; the range finder is prevented from toppling over, and the service life of the range finder is prolonged; and the maintenance cost of the range finder is reduced.
Description
technical field [0001] The invention belongs to the technical field of surveying and mapping, in particular to a composite laser ranging system. Background technique [0002] Laser distance measuring (laser distance measuring) uses a laser as a light source for distance measurement. According to the way the laser works, it is divided into continuous laser and pulsed laser. Gas lasers such as helium-neon, argon ions, and krypton-cadmium work in a continuous output state and are used for phase laser ranging; double heterogeneous gallium arsenide semiconductor lasers are used for infrared ranging; solid-state lasers such as ruby and neodymium glass are used for Pulsed laser ranging. Compared with the photoelectric range finder, the laser range finder can not only work day and night, but also improve the distance measurement accuracy due to the characteristics of good monochromaticity and strong directionality of the laser, and the integration of electronic circuits and semi...
