The utility model content
To the above-mentioned needs of industry, the utility model is intended to for traditional shearing type lifter increases a kind of cam safety device, with the lift height of convenient this shearing type lifter of locking, makes machine be unlikely to descend suddenly to meet accident.
Particularly, the utility model provides a kind of shearing type lifter, comprising:
A pair of lifting column;
A pair of scissors bracing frame, said a pair of scissors bracing frame is parallel and be arranged at the outside of said a pair of lifting column respectively;
Support platform be arranged at the top of said a pair of scissors bracing frame, and a side of said a pair of lifting column is fixed in the bottom of said a pair of scissors bracing frame and the position near said support platform that opposite side connects said a pair of scissors bracing frame; And
Cam safety mechanism is arranged between the said a pair of lifting column, to realize the locking and unlocking of said shearing type lifter.
According to a preferred embodiment of the utility model, in above-mentioned shearing type lifter, said cam safety mechanism further comprises: horizontal cross bar is across between the said a pair of lifting column; And the buckle bar, be set to perpendicular to said horizontal cross bar and be parallel to said a pair of lifting column; Wherein, said buckle bar has the buckle groove that several sides that can hold said horizontal cross bar are inserted.
According to a preferred embodiment of the utility model, in above-mentioned shearing type lifter, the opposite side place of said horizontal cross bar has a circular arc recess.
According to a preferred embodiment of the utility model, in above-mentioned shearing type lifter, said cam safety mechanism further comprises: cam, be fixed in said circular arc indent and can be rotated around one.
The shearing type lifter of the utility model can not have normal operation under the service conditions of external air source, locks the lift height of this shearing type lifter easily, makes machine be unlikely to descend suddenly to meet accident.
Should be appreciated that the above generality of the utility model is described and following detailed description all is exemplary and illustrative, and be intended to further explanation is provided for as claimed in claim the utility model.
Description of drawings
Accompanying drawing mainly is to be used to provide the utility model is further understood.Accompanying drawing shows the embodiment of the utility model, and plays the effect of explaining the utility model principle with this specification sheets.In the accompanying drawing:
Fig. 1 schematically shows the schematic structure of the shearing type lifter with cam safety device of the utility model.
Fig. 2 a shows the scheme drawing of a kind of mated condition of cam and horizontal cross bar.
Fig. 2 b shows the scheme drawing of the another kind of mated condition of cam and horizontal cross bar.
The specific embodiment
Describe the technical scheme of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 schematically shows the schematic structure of the shearing type lifter with cam safety device of the utility model.As shown in the figure, the shearing type lifter of the utility model mainly comprises: a pair of lifting column 101, a pair of scissors bracing frame 102, support platform 103 and cam safety mechanism.
As shown in Figure 1, this a pair of scissors bracing frame 102 is parallel and be arranged at the outside of a pair of lifting column 101 respectively.Support platform 103 is arranged at the top of said a pair of scissors bracing frame 102, and a side of said a pair of lifting column 101 is fixed in the bottom of said a pair of scissors bracing frame 102 and the position near said support platform 103 that opposite side connects said a pair of scissors bracing frame 102.Cam safety mechanism is arranged between the said a pair of lifting column 101, in order to realize the locking and unlocking of said shearing type lifter.
Particularly, cam safety mechanism may further include horizontal cross bar 104 and buckle bar 105.Horizontal cross bar 104 is across between the said a pair of lifting column 101.Buckle bar 105 is set to perpendicular to said horizontal cross bar 104 and is parallel to said a pair of lifting column 101.Preferably, said buckle bar 105 has the buckle groove 106 that several sides that can hold said horizontal cross bar 104 are inserted.This buckle groove 106 can be equidistantly perhaps to be arranged on the upper surface of this buckle bar 105 non-equidistance.
Forward Fig. 2 a and Fig. 2 b now to.Fig. 2 a shows the scheme drawing of a kind of mated condition of cam and horizontal cross bar.Fig. 2 b shows the scheme drawing of the another kind of mated condition of cam and horizontal cross bar.
The opposite side of said horizontal cross bar 104, promptly the side place away from said buckle groove 106 has a circular arc recess 202.
In addition, in above-mentioned shearing type lifter, said cam safety mechanism may further include: cam 201, be fixed in circular arc recess 202 places and can be rotated around one.Particularly, this rotation can be that the deadweight that relies on cam realizes.
Shown in Fig. 2 a, when the protuberance of said cam 201 was positioned at outside the said circular arc recess 202, horizontal cross bar 104 was not boosted, and made this horizontal cross bar 104 not insert above-mentioned buckle groove 106.This shearing type lifter is unlocked.The user just can utilize lifting mechanism 101 that the height of this shearing type lifter is regulated arbitrarily like this.
Shown in Fig. 2 b, when the protuberance of said cam 201 was positioned within the said circular arc recess 202, horizontal cross bar 104 will be boosted, and made this horizontal cross bar 104 insert above-mentioned buckle groove 106.The height of this shearing type lifter will be locked like this, make the user can't regulate the height of this shearing type lifter through lifting mechanism 101.
The shearing type lifter of the utility model can not have normal operation under the service conditions of external air source, locks the lift height of this shearing type lifter easily, makes machine be unlikely to descend suddenly to meet accident.
