The invention also discloses a method convenient for steering, and the skid steer loader convenient for steering comprises the following steps:

s1, when the transport vehicle loads the goods on the top end of the supporting seat to a narrow space and needs to drive the goods to steer, when the transport vehicle drives the goods to steer inconveniently, the hydraulic cylinder is started, the output end of the hydraulic cylinder extends to push the first rack to drive the second rack to move, the second rack drives the second straight gear to drive the big bevel gear to rotate through the second rotating shaft, so as to drive the small bevel gear to drive the one-way screw rod to rotate rapidly, the one-way screw rod drives the first sliding block to drive the first sealing piston block to slide in the second connecting shell in a rapid rotating manner,

s2, when the first sealing piston block slides in the second connecting shell, the gas in the second connecting shell is respectively pushed into the telescopic hose and the third guide pipe, when the gas in the second connecting shell enters the first connecting shell through the third guide pipe, the gas continuously enters the first connecting shell, so that the second sealing piston block is pushed to pull the first spring to move in the first connecting shell, when the second sealing piston block moves, the feeding port of the first connecting shell is firstly blocked, then the lubricating oil in the first connecting shell is extruded, the lubricating oil in the first connecting shell is respectively pushed into the second guide pipe, is guided into the injection shell through the second guide pipe, is injected into the outer wall of one side of the arc-shaped supporting block through the injection shell, and is guided to the bottom end of the arc-shaped supporting block and the outer wall of the other side through the guide groove formed in the bottom end of the arc-shaped supporting block, so that the arc-shaped supporting block is lubricated;

s3, when the gas in the second connecting shell enters the telescopic hose, the gas in the second connecting shell is led into the third connecting shell through the telescopic hose, when the gas in the second connecting shell continuously enters the third connecting shell through the telescopic hose, the third sealing piston block is pushed to drive one end of the third spring and the piston rod to move towards the outside of the third connecting shell, the third spring is extruded, when the piston rod moves towards a position far away from the third connecting shell, one third rack is driven to move, the third straight gear is driven to drive the other third straight gear to rotate through the bidirectional screw rod, the other third rack is driven to move, when the bidirectional screw rod rotates, the two sliding plates are driven to approach goods at the top end of the supporting seat, and the sliding plates drive the second sliding block to move while moving, so that the second sliding block slides at the top end of the third sliding block;

s4, when the two sliding plates approach to the goods, one clamping plate is driven to approach to the goods through one rotating block, when the clamping plate abuts against the outer wall of the goods, the sliding plates continue to approach to the goods, so that the rotating blocks are pushed to drive one end of the torsion spring to rotate through the third rotating shaft, the torsion spring is twisted, when a latch at the bottom end of one third rack is separated from the third straight gear, the sliding plates move to the maximum position, and the third rack continues to move so that the fixed block is driven to move, when the fixed block is contacted with the third sliding block, the third sliding block is pushed to extrude the second spring to approach to the third connecting shell, when the third sliding block moves towards the third connecting shell, the two straight gear rings are driven to move through the second sliding block, and when the third rack moves to the maximum position, the two straight gear rings are respectively meshed with one fourth straight gear, so that the third rotating shaft is limited, and the goods at the top end of the supporting seat are limited through the clamping plate;

s2, when the second rack outer wall latch with when the second straight-teeth gear separates, first rack outer wall latch with first straight-teeth gear contact to the drive first straight-teeth gear passes through first pivot drives the supporting seat rotates, thereby drives supporting seat top goods rotates, and it is right with this the supporting seat top goods position is adjusted.

Compared with the prior art, the invention has the beneficial effects that:

1. by arranging the steering adjusting mechanism and the self-adaptive clamping mechanism, when the transport vehicle loads goods to a narrow space and needs to drive the goods to steer, when the transport vehicle drives the goods to steer inconveniently, the steering adjusting mechanism steers the goods to adjust the position of the goods, so that a worker can conveniently transport the goods in the narrow space through the transport vehicle, the two sides of the goods at the top end of the transport vehicle are limited through the self-adaptive clamping mechanism, the goods are prevented from shaking in the steering process, the stability of the goods during steering is improved, and the goods are conveniently and stably driven to steer by the steering adjusting mechanism;

2. through setting up steering control mechanism, when the transport vechicle loads the goods on supporting seat top to narrow and small space and need drive the goods and turn to, when the transport vechicle drives the goods and turns to inconveniently, start the pneumatic cylinder, when the output extension of pneumatic cylinder promotes first rack and removes, when first rack outer wall latch and first straight gear contact, thereby drive first straight gear and drive the supporting seat through first pivot and rotate, thereby drive supporting seat top goods and rotate, adjust supporting seat top goods position with this, lubricate two arc supporting shoes and transport vechicle contact site through lubricating assembly, so that two arc supporting shoes can be better rotate, avoid two arc supporting shoes to take place to block at the pivoted in-process, so that the supporting seat can be convenient rotate on the transport vechicle top through two arc supporting shoes, the function that turns to the goods has been realized through the cooperation of above a plurality of parts, so that the transport vechicle can drive the goods in constrictive space and turn to.

3. Through setting up self-adaptation fixture, fix the grip block at the outer wall of goods through self-adaptation fixture, carry on spacingly to the goods to this avoids the supporting seat to drive the in-process that the goods turned to and takes place to rock, thereby makes the drive goods that the supporting seat can be stable turn to.
