Abstract
The utility model relates to an amplitude-change system of a sideboom tractor, which comprises a sideboom tractor; a lifting arm is arranged at the front end of the sideboom tractor; a hanging hook is arranged at the upper end of the lifting arm; and the hanging hook is connected with a hoisting machine arranged on the sideboom tractor through a steel cable. The amplitude-change system is characterized in that the bottom end of the lifting arm is hinged with the sideboom tractor, the lifting arm is further connected with an oil cylinder used for changing the elevation angle of the lifting arm, and a counterweight used for balancing the lifting arm is also arranged at the rear end of the sideboom tractor. The utility model realizes the accurate positioning of hoisting through the accurate control of the hydraulic transmission system and reduces the labor intensity to the utmost extent; and meanwhile, the utility model performs real-time monitoring on the relevant parameters of the complete machine by using the sensor detection technology, sends information to the control system and performs real-time adjustment to the counterweight system through analysis and computation according to the change of working conditions of hoisting, thereby ensuring a sufficient balancing torque during the work of the sideboom tractor and avoiding the overthrow accident.
Description
Technical field
The utility model belongs to technical field of engineering machinery, the swing pipe machinery of specifically a kind of pipeline construction, maintenance usefulness.
Background technology
Pipe sling is the specialized equipment that oil and natural gas pipeline is laid, in recent years, because China is to the vigorous development of energy demand, the construction of natural fuels and petroleum pipe line has also obtained fast development, the demand of pipe sling is increased, especially have accurate lifting location, pipe sling demand that safety performance is good is very big.
More and more amount is big in the applying working condition of pipe sling and lifting now, in operation process, mostly be the multimachine work compound, the pipe sling luffing mostly is the elevator luffing at present, be subject to the behavior of structure of used hoisting mechanism, in the pipeline hoisting process, be difficult to comparatively accurately lift put in place, often need correction work repeatedly.Work efficiency is slow, the working process complexity.
The patent of the CN201087082Y of Chinese patent Granted publication, a kind of novel pipe hanger that auxiliary boom is housed.Include pipe sling, it is characterized in that being hinged with auxiliary boom in the upper end of the arm of pipe sling.Auxiliary boom cooperates with the arm of pipe sling and bears hoisting weight jointly during operation.But the auxiliary boom structure that it is equipped with is huge, installs and uses very inconvenience.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of laying tractor changing-breadth system is provided.
In order to address the above problem the technical solution of the utility model is such:
The laying tractor changing-breadth system, comprise a laying tractor, the pipe sling front end is provided with arm, the arm upper end is provided with suspension hook, described suspension hook connects a winch that is arranged on the pipe sling by wirerope, it is characterized in that described arm bottom and pipe sling are hinged, described arm also connects an oil cylinder that is used to change the arm elevation angle, and the pipe sling rear end also is provided with the counterweight that is used for the balance arm.
Described arm middle part has a crossbeam, and described oil cylinder one end is connected that the other end is connected on the pipe sling on the crossbeam.
Described counterweight is connected on the pipe sling by weight arm, and described weight arm is adjustable length weight arm.
Beneficial effect, the utility model is by the accurate location of accuracy control to realize lifting of power hydraulic system, and maximum limit ground reduces labour intensity.Utilize sensor detecting simultaneously, the complete machine correlation parameter is monitored in real time, and feed back to control system, calculate by analysis,, Weighting system is carried out real-time adjusting according to the working conditions change of lifting, to guarantee that pipe sling has enough balancing torques when working, avoid the generation of overthrow accident.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of laying tractor changing-breadth system described in the utility model;
Fig. 2 is the construction profile scheme drawing of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The utility model is based on big caliber 70t laying tractor chassis, consider in pipe sling operation operating mode and the hoisting process pinpoint requirement, with traditional arm elevator luffing structure, change single hydraulic ram luffing structure into, by the accurate adjusting of hydraulic circuit to the oil cylinder flow, being implemented in the hoisting process control of lifting position, the error of having avoided traditional hoisting mechanism to bring because of the mechanical drive of each side in amplitude changing process has increased the stability of operation.
Referring to Fig. 1 and Fig. 2
Pipe sling mainly comprises the chassis 1 that has crawler belt, is arranged on The One On The Chassis arm 2, is arranged on the suspension hook 3 on the arm 2, and arm 2 links to each other with chassis 1 by a chassis overhang 4.Chassis overhang 4 one ends are provided with arm 2 other ends counterweight 6 are set.Counterweight 6 is used for the weight of balance arm 2 and the weight of the pipeline sling, and described counterweight 6 is connected on the chassis overhang 4 by weight arm 61, and weight arm 61 is adjustable length weight arm.To be structure as a whole and to melt with the chassis be a rigid unitary to chassis overhang 4 in addition, improved structural stability.In chassis overhang 4 upper boom portion 2 one sides, be provided with a winch 31, winch 31 is by wirerope connecting shackle 3, and driving suspension hook 3 lifts by crane up and down.Oil cylinder 5 one ends link to each other with chassis overhang 4, and the other end links to each other with the crossbeam 21 at arm 2 middle parts, and by three dimensional design and force analysis, determine its best position of articulating point.In hoisting process, adjust the flow size of amplitude oil cylinder by hydraulic control handle valve, make oil cylinder 5 accurately flexible, drive arm 2 folding and unfoldings, can accuracy control arm 2 elevations angle, make by the swing pipe road and accurately locate.
Pass through torque sensor simultaneously, the hoisting capacity sensor, displacement pickups etc. are monitored the situation of change of the every correlation parameter of pipe sling in the hoisting process in real time, and with signal feedback in single-chip computer control system, after calculating by analysis, send instruction by micro controller system, balance weight mechanism is carried out real-time regulated, to reach the balance of counterweight and lift heavy applied moment on the chassis, in hoisting process, be controlled at machine gravity within the reasonable range, avoided the generation of overthrow accident, thereby the stability and the safety of complete machine operation have been improved greatly, the performance requriements when satisfying multiple devices work compound.
The utility model is by the accurate location of accuracy control to realize lifting of power hydraulic system, and maximum limit ground reduces labour intensity.Utilize sensor detecting simultaneously, the complete machine correlation parameter is monitored in real time, and feed back to control system, calculate by analysis,, Weighting system is carried out real-time adjusting according to the working conditions change of lifting, to guarantee that pipe sling has enough balancing torques when working, avoid the generation of overthrow accident.
