Description
Technical Field
The invention belongs to the technical field of vehicle-mounted oil rigs, and particularly relates to a double-power interlocked three-dimensional gear shifting mechanism which is particularly suitable for being mounted on a gearbox of a vehicle-mounted oil rig.
Background
The transmission gearbox is a core component of a power transmission system in the vehicle-mounted drilling machine, is a tie for power transmission of each working machine, and relates to the overall layout of the drilling machine and important working performance of the drilling machine. The transmission gearbox with good performance has the characteristics of high transmission power, high efficiency, sensitive operation, compact structure, convenient use and convenient maintenance, can furthest meet the requirements of the movement and the processing technology of the vehicle-mounted drilling machine, and can meet the drilling machine torque and the drilling speed range of different industrial and mining requirements. For the vehicle-mounted oil rig gearbox with high installed power, a double-power structure is generally adopted, so that gears are used for combining carriages. The large-scale vehicle-mounted drilling machine has the advantages that the vehicle-mounted drilling machine is complex in working condition and large in load change range, single-machine operation or double-machine parallel operation is needed to be used alternately according to load change, and therefore, a set of hanging devices are arranged at the input end of each parallel carriage, power transmission between an engine and the parallel carriage can be cut off or communicated, and a gear shifting hanging device is arranged at each output end of the carriage according to the working condition. According to different working conditions, the two engines can work singly or operate in parallel, and the power of the four output ends can be switched at will but the vehicles are interlocked. When the vehicle works, the hanging device at the output end of the front axle and the rear axle driven by the lower end of the parallel carriage is in a disconnecting state. The switching between the power inputs must be operated before the engine is started or while the car is in neutral, otherwise noise or damage to the gear engagement components may be caused.
The speed reducer installed in the vehicle-mounted oil rig gearbox mainly comprises two input ends (namely a power input end I and a power input end II) and an output end. The power input end II and the output end are the same shaft, the connecting flanges of the power input end II and the output end are the same, the power input end II is diesel oil input and is only used as emergency power input, and a hanging device is arranged outside the power input end II; the power input end I can realize the switching of three states of high gear, neutral gear and low gear through a gear shifting structure. The two power input ends are interlocked through manual engagement, and cannot work simultaneously. The working states are two: the power input end I provides power, the power input end II is in a neutral state, the rotation speed of an output shaft is controlled by an on-vehicle gear shifting device, and the power input end I can provide three states of high gear, neutral gear and low gear; and the power input end II and the output shaft are the same shaft, so that the power is directly input by the power input end II and is directly output in a 1:1 speed ratio state without any shaft.
The gear shifting device installed in the gearbox of the vehicle-mounted petroleum drilling machine is generally improved on the basis of a single gear shifting structure (see fig. 1 in detail) commonly used in the automobile industry, and a sensor is used for controlling a circuit, so that gear shifting is realized. The working principle of a single gear shifting structure in the automobile industry is as follows: when the vehicle-mounted drilling machine needs to work, the gear shifting handle (1 ') is pulled by force, the gear shifting handle (1 ') uses the fixing seat (8 ') as a fulcrum, the gear shifting fork (4 ') is pulled by the shifting fork rod (3 ') through the connector (2 '), the gear shifting fork (4 ') is hung on the gear shifting inner gear sleeve (5 '), then the gear shifting fork (4 ') drives the gear shifting inner gear sleeve (5 ') to move so as to realize the hanging of the inner gear sleeve and different gears (left gear 6', right gear 7 '), and the gear shifting inner gear sleeve (5 ') is hung with different gears so as to realize different speed ratios, and finally, the gear shifting aim of switching among three states of high-grade, neutral and low-grade is realized. The single gear shifting device of the traditional vehicle-mounted petroleum drilling machine is controlled by the circuit sensor, and has the advantages of simple and convenient operation; but the disadvantages are also more pronounced: if the circuit sensing single gear shifting device of the traditional vehicle-mounted petroleum drilling machine works in severe working conditions in the wild and desert areas, the problems of circuit short circuit, aging and the like are easy to occur, the use safety and reliability are difficult to ensure, and in addition, the processing difficulty of a gearbox for an automobile is high, the maintenance cost is high, and the disassembly and the maintenance are difficult to realize, so that the circuit sensing single gear shifting device is not suitable for the severe working conditions; and (II) the gear shifting device in the gearbox of the traditional vehicle-mounted petroleum drilling machine is of a single gear shifting structure, and only one input state is provided, namely, the gear shifting device with one input state is provided for the engine, and the gear shifting devices with two or more input states and the interlocking between the two sets of gear shifting devices are not involved, so that the requirement of the high-power vehicle-mounted petroleum drilling machine on complex working conditions is not met, namely, the requirement that the load change range in the complex working conditions is large and the power input needs to be flexibly adjusted according to the load change cannot be met.
