Existing lifting catch gear generally is latch lifting catch gear, gear lifting catch gear and the spring lifting catch gear of using always.Such as, Chinese patent CN201325827 discloses a kind of auto-locking suspension hanging apparatus and uses jacking system, comprises entablatrance and cross sill; The two ends of said entablatrance and cross sill are symmetrically installed with vertical vertical rod, and the outside of vertical rod is equipped with the Hydraulic Station mounting bracket, and the lower end of entablatrance is equipped with and the hydraulic actuating cylinder connecting panel; Hydraulic Station bonded assembly hydraulic actuating cylinder is installed on the hydraulic actuating cylinder connecting panel; The other end of hydraulic actuating cylinder connects cross sill, and the bilateral symmetry of cross sill is equipped with pilot sleeve, and pilot bar is installed in the pilot sleeve; The lower end of pilot bar is equipped with the guiding anchor clamps, the lower end mounting flange of guiding anchor clamps.
There is following defective in existing lifting catch gear:
1, complex structure, parts are numerous, and cost is high.
2, inconvenient operation need be used instrument.
3, the lifting locking force is not enough, is easy to generate the slit, and the risk that comes off is arranged, and safety factor is low.
The utility model content
The utility model proposes a kind of locking type hanging apparatus simple in structure, through easy operation, produces bigger locking force, has complex structure, operation inconvenience and the not enough technical matters of lifting locking force to solve present lifting catch gear.
The utility model adopts following technical scheme to realize: a kind of locking type hanging apparatus, and it comprises: supporting seat; Run through the spreading axis among the mesopore that is arranged on supporting seat, have screw thread on the shank lateral surface of spreading axis; Gu the upper limit position block on supporting seat; The thumb wheel that center shaft and spreading axis are screwed; Gu on supporting seat, make the spreading axis can't be with the lower limiting board of thumb wheel rotation; Be fixed on the expansion pin on the supporting seat, and the top of spreading axis is set among the expansion pin; Locking is arranged on the bearing block on the expansion pin.
Wherein, said hanging apparatus comprises: at thrust baring of each socket of two ends of the center shaft of thumb wheel.
Wherein, the position-limited trough of setting of the bottom of spreading axis and lower limiting board clamping.
Wherein, the upper outside face of expansion pin is set to the inclined-plane.
Wherein, the inner side of bearing block is set to the inclined-plane.
Wherein, the top of spreading axis is configured such that the open taper in top of expansion pin.
Compared with prior art, the utlity model has following beneficial effect:
The locking type hanging apparatus that the utility model proposes is to utilize simple structure; Through easy operation; Produce bigger locking force, when 2 tons of liftings or above weight, the slit that two parts produced up and down of locking is no more than 0.2mm; And do not come off, improved the safety of lifting operation.

The specific embodiment
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the utility model proposes a kind of locking type hanging apparatus simple in structure, and it comprises: supporting seat 1, the middle part of this supporting seat 1 have a mesopore; Run through the spreading axis 2 that is arranged among supporting seat 1 mesopore, have screw thread on the shank lateral surface of this spreading axis 2, and the bottom of spreading axis 2 is provided with position-limited trough 21, and top is set to taper; Through the upper limit position block 1 of flat head screw locking on supporting seat 1, the shank of spreading axis 2 runs through the through hole that passes this upper limit position block 1 middle part setting; The thumb wheel 4 that screw thread on center shaft and spreading axis 2 shanks screws togather; And thrust baring 5 of each socket of the two ends of the center shaft of thumb wheel 4; Through the lower limiting board 6 of screw locking on supporting seat 1, this lower limiting board 6 matches with the position-limited trough 21 of spreading axis 2 shank bottoms; Be fixed on the expansion pin 7 on the supporting seat 1, and the top of spreading axis 2 is set among the expansion pin 7, and the upper outside face of expansion pin 7 is set to the inclined-plane; Locking is arranged on the bearing block 8 on the expansion pin 7.
Like this, spreading axis 2 is fixed on the supporting seat 1 through upper limit position block 3 and lower position block 6 with thumb wheel 4, and bearing block 8 then tightens locking on expansion pin 7.
In conjunction with shown in Figure 4, because the screw thread on the shank lateral surface of the center shaft medial surface of thumb wheel 4 and spreading axis is screwed, simultaneously, owing to two ends thrust baring 5 of each socket of the center shaft of thumb wheel 4 is fixedly installed between upper limit position block 3 and the lower position block 6.Therefore, when manually stirring thumb wheel 4, thumb wheel 4 makes on the spreading axis 2 and moves, and by the top of spreading axis 2 expansion pin 7 is opened, thereby bearing block 8 is clamped on the expansion pin 7, prevents that bearing block 8 from coming off from expansion pin 7.
In the process of locking bearing block 8, during trackwheel 4, follow spreading axis 2 and rotate together in order to prevent spreading axis 2, thus increased the position-limited trough 21 that is connected on the lower position block 6 in the bottom of spreading axis 2, thus make spreading axis 2 can only do perpendicular movement.When needs unclamp bearing block 8, to stir thumb wheel 4 it is moved in the opposite direction, spreading axis 2 will move (promptly descending) vertically downward, and the top of expansion pin 7 merges, thus bearing block 8 is able to come off from expansion pin 7.
Because the upper outside face of expansion pin 7 is set to the inclined-plane, like this, when expansion pin 7 was opened, firm more easily tightened bearing block 8, and bearing block 8 can't be come off from the top of expansion pin 7.Inner side at bearing block 8 also is set to the inclined-plane simultaneously, so conveniently overlaps bearing block 8 to expansion pin 7.
To sum up; The locking type hanging apparatus that the utility model proposes is to utilize simple structure, through easy operation, produces bigger locking force; When 2 tons of liftings or above weight; The slit that two parts produced up and down of locking is no more than 0.2mm, and does not come off, and has improved the safety of lifting operation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
