Background
When a wheel type construction machine or a semitrailer carries out load bearing operation, a certain supporting mechanism is required as a main load bearing member. The swing leg is a commonly used supporting mechanism capable of realizing horizontal swing. The swing leg hinge point is a key node for connecting the swing leg and the frame structure, so that the swing leg can normally rotate and bear bending moment and shearing force transmitted by the counter force of the swing leg, and the swing leg pin shaft at the hinge point is required to have higher machining precision, matching precision and wear resistance. The coaxiality and the assembly precision are high, so that the dismounting and mounting process of the leg swinging pin shaft is very difficult.
In order to solve the problem that the leg swing pin shaft is difficult to disassemble and assemble, the current method is to divide the leg swing hinge point into an upper hinge point and a lower hinge point, and the leg swing pin shaft is correspondingly divided into an upper part and a lower part so as to reduce the overall height and the disassembling and assembling space requirements of the leg swing pin shaft. At present mainly there are two kinds of pendulum leg round pin axle dismouting schemes, and the dismouting thinking is enough as the prerequisite with the upper and lower space, and upper and lower hinge point pendulum leg round pin axle carries out the dismouting from the upper and lower side respectively:
(1) Manual disassembly and assembly: the pin shaft dismounting and mounting are completed completely by bare hands and auxiliary measures without any special pin shaft dismounting and mounting mechanism, and the small-tonnage wheel type engineering machinery and the bearing operation semitrailer are commonly adopted;
(2) The hydraulic device is plugged in and pulled out of the pin shaft: for a large swing leg pin shaft which cannot be operated by bare hands, the pin shaft is inserted and pulled out through hydraulic drive, and large-tonnage wheeled engineering machinery is commonly used.
The two existing mounting solutions have the following disadvantages:
(1) Bare-handed dismouting is wasted time and energy, and is higher to workman skill level requirement, and the dismouting process squeezes one's hand easily, has the potential safety hazard.
(2) The hydraulic device plug pin shaft needs an external power source, and is high in cost, complex in structure and poor in maintainability.
(3) The existing leg swinging pin shaft dismounting mode cannot solve the problem that the space of a certain direction of the leg swinging pin shaft is limited, and the leg swinging pin shaft with an upper hinge point and a lower hinge point can only be dismounted from the other direction.
