Abstract
A rotary drilling rig rotation detecting device belongs to a rotation detecting device of engineering equipment, and comprises an encoder, a support, a bearing, a roller, a rotation shaft, a torsion spring and a bracket, wherein the shaft is fixed on the support through the bearing, the encoder is sleeved on the upper end of the shaft, the roller is integrally connected with the shaft, the rotation shaft is connected on the other end of the support, the torsion spring is arranged on the rotation shaft, a plate is connected with the torsion spring through a spring clamp, the bracket is fixed on the rotation shaft, a fixed mount is welded on the lower plane of a rotary table bottom board, and the bracket is integrally connected with the fixed mount. The rotary drilling rig rotation detecting device has the advantages of simple structure, convenient installation, reliable performance and high detection precision, the roller is made from nylon, and has certain hardness for avoiding deformation through splashing adhesive on the circumference surface of the roller, the friction of the cylindrical surface of the roller is increased, and the roller is assured not to slide when rolling on the outer surface of a chassis gear base, thereby eliminating detection errors.
Description
Technical field
The utility model relates to a kind of rotation detecting of engineering machinery, particularly a kind of Operation of Rotary Pile Drill pick-up unit.
Background technology
At present, the get on the bus detection of angle of revolution and direction of rotary drilling rig mostly provides signal by speed probe is installed on the rotary motor, or the method that scrambler is installed in by shaft coupling on the central chassis pinion stand of vehicle realizes.First method, when motor rotates, produce and export one with the proportional signal of rotating speed, the sensor that this signal is complementary with it arrives.But have many motors not to be with the speed probe interface, also have some rigs directly to select the import chassis for use, institute mates horses to reach and does not also have this interface, so just can't carry out the detection of angle of revolution; Second method, the accuracy requirement that scrambler and shaft coupling are installed is higher, and very strict with the right alignment requirement of vehicle chassis pinion stand, it is bigger to detect error in the practical application, and can't satisfy request for utilization.
The utility model content
The purpose of this utility model provides a kind of simple in structure, Operation of Rotary Pile Drill pick-up unit that can accurately measure the angle of revolution.
The purpose of this utility model is achieved in that this mechanism is by scrambler, bearing, bearing, roller, rotating shaft and torsion spring be configured to, axle (7) is fixed on the bearing (5) by bearing (4), scrambler (6) is socketed in the upper end of axle (7), and roller (2) connects as one with axle (7); The other end at bearing (5) is connected with rotating shaft, and torsion spring (10) is arranged in rotating shaft (8), and plate (11) links together by Spring Card (9) and torsion spring (10); Support (12) is fixed in the rotating shaft (8), and fixed mount (13) is welded on the lower plane of turntable base plate, and support (12) and fixed mount (13) link into an integrated entity.
Beneficial effect, owing to adopted such scheme, this rotation detecting is installed on the lower plane of rotary drilling rig turntable by support, its roller relies on the tension force of torsion spring in this device to be pressed on the outer cylinder surface of chassis pinion stand, when rotary drilling rig is got on the bus the revolution operation, the turntable rotation, roller just rolls along the external diameter of chassis pinion stand, the angle and the direction of rotation are got off with two dephased pulse recordings by scrambler, and be input to controller by scrambler, by the ratio of chassis pinion stand and roller diameter, can calculate chassis pinion stand rotating angle of relative rig upper frame part and direction.Simple in structure, can accurately measure the angle of revolution, reached the purpose of this utility model.Advantage is: 1, simple in structure, easy for installation 2, dependable performance, accuracy of detection height; 3, the material of roller is a nylon, and having carried out bold and vigorous glue on the periphery of roller handles, make roller both keep certain rigidity, prevent distortion, increased the friction force on the roller face of cylinder again, when guaranteeing that roller rolls on the pinion stand outside surface of chassis, can not produce any slip and eliminate the detection error.
