Abstract
The utility model discloses a lifting self-locking mechanism of an ultra-thin large-scissor lifting machine. The lifting self-locking mechanism of the ultra-thin large-scissor lifting machine solves the technical problems that supporting platforms of a single-rack self-locking mechanism adopted in an existing ultra-thin large-scissor lifting machine are easily rocked, and self-locking can not be achieved during a lifting process. The lifting self-locking mechanism of the ultra-thin large-scissor lifting machine is characterized in that extensible square tubes are installed in fixed square tubes, a check rack is installed inside each extensible square tube, a hinge pin is installed on the fixed square tubes through hinge pin fixing plates, a separated shifting fork and check pawls meshed with the check racks are installed on the hinge pin, the check pawls are connected through a pawl connecting rod, and the top end of a piston rod of a separated air cylinder is connected with the separated shifting fork. A reset spring is fixed on a reset spring fixing plate. The other end of the reset spring is fixed on the pawl connecting rod. The lifting self-locking mechanism of the ultra-thin large-scissor lifting machine has the advantages that due to the fact that the mechanism of the two check racks is adopted, stability of the supporting platforms can be ensured and a reset spring and the check pawls are under a tensioning state from beginning to end, the self-locking of the ultra-thin large-scissor lifting machine during the lifting process is achieved, danger caused by the fact that the lifting self-locking mechanism loses effectiveness during the lifting process is avoided, and the lifting self-locking mechanism of the ultra-thin large-scissor lifting machine is safe and reliable.
Description
Technical field
The utility model belongs to the auto hoist technical field, the particularly ultra-thin lifting machine lifting self-locking mechanism of cutting greatly.
Background technology
In the prior art, the ultra-thin both at home and abroad lifting machine of cutting greatly generally adopts each support platform tooth bar self-locking mechanism that places an order, purpose is when the lifting machine lifts automobile, prevent that the whereabouts is accidents caused suddenly because system down causes the lifting machine, the technical matters that this self-locking mechanism exists is because employing is the self-locking of monodentate bar, to rock easily between support platform, and can not self-locking in the lifting process, only after putting in place, lifting could realize self-locking.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, safe and reliable, and can realize the ultra-thin lifting machine lifting self-locking mechanism of cutting greatly of self-locking in the lifting process.
2 fixing square tubes about the technical solution adopted in the utility model comprises, about 2 fixedly install in the square tube can be in mobile flexible square tube in the fixing square tube, the retaining tooth bar is installed in 2 flexible square tubes, fixedly by the bearing pin adapter plate bearing pin is installed on the square tube at 2, on bearing pin, install and break away from shift fork and 2 and retaining tooth bar ingear retaining ratchet, 2 retaining ratchets connect by the ratchet connecting rod, at 2 the disengaging cylinder is installed between the square tube fixedly, the piston rod top of described disengaging cylinder links together with the disengaging shift fork, fixedly also be welded with the retracing spring adapter plate between the square tube at 2, fixed reset spring on the retracing spring adapter plate, the retracing spring other end is fixed on the ratchet connecting rod.
Compared with prior art, the beneficial effects of the utility model are: because the utility model is contained between the ultra-thin strut bar of cutting the lifting machine greatly, and be two retaining rack mechanisms, can guarantee the stability of support platform, because retracing spring is in tension with the retaining ratchet all the time by the ratchet connecting rod, can guarantee that the ultra-thin lifting machine retaining ratchet in uphill process of cutting greatly contacts under the effect of retracing spring all the time with the retaining tooth bar, thereby realize the ultra-thin lifting machine self-locking in the lifting process of cutting greatly, and 2 retaining ratchets connect by the ratchet connecting rod, can guarantee synchronized operation, avoid that system down causes danger in the uphill process, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model retracing spring scheme of installation.
Among the figure:
1. fixing square tube, 2. bearing pin adapter plate,
3. bearing pin 4. retaining ratchets,
5. flexible square tube, 6. retaining tooth bar,
7., ratchet connecting rod 8. breaks away from shift fork;
9. disengaging cylinder, 10. retracing spring,
11, the retracing spring adapter plate.
The specific embodiment
Provide the utility model specific embodiment below in conjunction with accompanying drawing.
As shown in drawings, 2 fixing square tubes 1 about the utility model comprises, about 2 fixedly install in the square tube 1 can be in mobile flexible square tube 5 in the fixing square tube 1, retaining tooth bar 6 is installed in 2 flexible square tubes 5, fixedly by bearing pin adapter plate 2 bearing pin 3 is installed on the square tube 1 at 2, on bearing pin 3, install and retaining tooth bar 6 ingear retaining ratchets 4 and disengaging shift fork 8,2 retaining ratchets 4 connect by ratchet connecting rod 7, at 2 disengaging cylinder 9 is installed between the square tube 1 fixedly, the piston rod top of described disengaging cylinder 9 links together with disengaging shift fork 8, fixedly be welded with retracing spring adapter plate 11 between the square tube 1 at 2, fixed reset spring 10 on retracing spring adapter plate 11, retracing spring 10 other ends are fixed on the ratchet connecting rod 7.
During work, the utility model is installed between the ultra-thin strut bar of cutting the lifting machine greatly, and when cutting the lifting machine greatly and rising, retaining tooth bar 6 is along with flexible square tube 2 is stretched out when ultra-thin, retaining ratchet 4 under the effect of retracing spring 10 with retaining tooth bar 6 closed contacts, realize self-locking; Because retracing spring 10 is in tension with retaining ratchet 4 all the time, can guarantee that the ultra-thin lifting machine retaining ratchet 4 in uphill process of cutting greatly contacts under the effect of retracing spring 10 all the time with retaining tooth bar 6, thereby realize the ultra-thin lifting machine self-locking in the lifting process of cutting greatly, avoid that system down causes danger in the uphill process., break away from cylinder 9 and start when cutting the lifting machine greatly and falling when ultra-thin, pulling breaks away from shift fork 8, breaks away from shift fork 8 pulling ratchet connecting rods 7, and ratchet connecting rod 7 drives retaining ratchets 4, and retaining ratchet 4 and retaining tooth bar 6 are broken away from, and the ultra-thin lifting machine of cutting greatly falls to finishing.
