Further, first end of connecting rod and contiguous block articulate.
Further, contiguous block is welded on the crane arm.
Further, at the two ends of bearing a limit switch mount pad is set respectively.
Further, bearing is U type cross section, comprises a base plate and two side plates, and first slideway and second slideway are the chute that is arranged on the side plate of bearing.
Further, second end of connecting rod is limited in second slideway through bearing pin.
According to a further aspect in the invention, a kind of hoisting crane is provided, has equilibrium arm, crane arm and crane arm luffing inhibiting device, this crane arm luffing inhibiting device are above-mentioned crane arm luffing inhibiting device
Pass through technique scheme; The major advantage of the utility model is; With connecting rod crane arm and equilibrium arm are coupled together, connecting rod and equilibrium arm coupling end are limited in the horizontal slide rail, the luffing motion that transforms crane arm is horizontal motion; And also place slide rail to the slide block that is loaded with limit switch, realize the spacing of crane arm optional position.The client can come the spacing of any amplitude of control tower machine according to the building site actual needs of oneself.
Description of drawings
The accompanying drawing that constitutes the part of the utility model is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the assembling scheme drawing of crane arm luffing inhibiting device of an embodiment of the utility model; And
Fig. 2 shows crane arm luffing inhibiting device and crane arm and the equilibrium arm bonded assembly scheme drawing of an embodiment of the utility model.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The crane arm inhibiting device of an embodiment of the utility model has been shown among Fig. 1.This inhibiting device mainly comprises three assemblies:
1, bearing 10; Be welded on the equilibrium arm 60, main effect is that bearing 10 is U type cross section for connecting rod 30 and limit switch mount pad 20 provide slideway and support; Comprise a base plate and two side plates, two long chutes on the bearing biside plate are first slideway 11 and second slideway 12.
2, the limit switch mount pad 20; Be fixed by bolts on the bearing 10; Main effect is himself can to move for 11 li at first slideway of bearing simultaneously for limit switch provides the installation site; The tapped bore of limit switch mount pad 10 both sides is used for fixing it in first slideway 11 that the bearing both sides are leaned on, and two tapped bore of bottom surface are used for fixing limit switch.Preferably, the first limit switch mount pad 20 and the second limit switch mount pad 21 are set respectively at bearing 10 two ends.
3, connecting rod 30; The lower end through bearing pin be limited in the bearing left and right sides by under second slideway 12 in; The contiguous block 40 that welds on upper end and 50 times main strings of crane arm articulates; Main effect is that crane arm 50 and bearing 10 are connected, and becomes the horizontal motion of connecting rod 30 lower ends in bearing second slideway 12 to the movement conversion of luffing up and down of crane arm 50.
This inhibiting device also comprises in addition, and limit switch is installed on the limit switch mount pad 20, and the selection of limit switch can be the same with the used limit switch of prior art.
As shown in Figure 2, the utility model crane arm inhibiting device is installed between crane arm 50 and the equilibrium arm 60, through connecting rod 30 both is connected; Because equilibrium arm 60 level attitudes are constant, bearing 10 is welded on the equilibrium arm 60, and an end of connecting rod 30 is limited in second slideway 12 of the inhibiting device shown in Fig. 1; The other end links to each other with crane arm 50 lower edges; When crane arm 50 luffings, 30 motions of crane arm 50 drivening rods, horizontal motion is done in connecting rod 30 lower ends in second slideway.On the limit switch mount pad 20,21 of right ends, limit switch is installed, sliding along second slideway when connecting rod 30 lower ends touches the limit switch contact, the moving of limit switch induction stopping crane arm 50, thus realize position-limiting action to crane arm 50 luffings.Simultaneously; Because the slide block of connecting rod lower end and the installation slideway of limit switch mount pad 20 all are elongated track; The position of limit switch mount pad 20 can be fixed on the optional position on first slideway 11; Can realize spacing for different amplitudes like this, the user can realize the spacing of optional position according to the building site demand of oneself.
Crane arm inhibiting device according to the utility model has following beneficial effect: the client can come the spacing of any amplitude of control tower machine according to the building site actual needs of oneself.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
