Abstract
The utility model provides a mechanism used for the left and right swinging of an excavating device, which comprises the excavating device, a swinging seat, a fixed seat and two hydraulic oil cylinders, wherein one end of the excavating device is hinged with one end of the swinging seat; the other end of the swinging seat is hinged with the fixed seat, the hydraulic oil cylinders are arranged in the fixed seat and take the structure of bilateral symmetry; and output ends of the hydraulic oil cylinders are respectively extended out of the fixed seat and are hinged with the two sides of the swinging seat. The utility model has the benefits as follows: the mechanism realizes the use requirements for the left and right swinging of 90 degrees of the excavating device and has the advantages of stable power transmission, convenience in control, simple structure, convenience in maintenance, lighter weight, long service life, low maintenance cost and the like.
Description
Technical field
The utility model belongs to engineering machinery field, especially relates to a kind of mechanism that excavating gear swings that is used for.
Background technology
In the prior art, the rotation of excavator excavating gear normally relies on the revolution of fuselage to realize, fuselage drives by a cover reducing gear and realizes rotation, its shortcoming is this mechanism structure complexity, weight is bigger, and member is easy to wear, and application life is short, maintenance is inconvenient, and cost is more high.
Summary of the invention
The utility model is a kind of to be used for the mechanism that excavating gear swings, and its purpose will solve deficiency of the prior art exactly, provides a kind of simple in structure, weight is lighter, easy to maintenance, cost is lower, can satisfy the positive and negative 90 ° of instructions for uses that swing of excavating gear.
The technical solution of the utility model is: a kind ofly be used for the mechanism that excavating gear swings, comprise excavating gear, swing seat, holder and hydraulic jack, one end of the hinged swing seat of one end of excavating gear, the other end and the holder of swing seat are hinged, be provided with two hydraulic jacks in the holder, two hydraulic jacks are the bilateral symmetry structure, and the output of two hydraulic jacks stretches out holder respectively, and hinged respectively with the both sides of swing seat.
Preferably, this mechanism also comprises snubber block, and described snubber block is installed on the holder and is positioned at the left and right sides of swing seat and holder hinged place.
Advantage and the good effect that the utlity model has are: adopt technique scheme, realized the positive and negative 90 ° of instructions for uses that swing of excavating gear, and it is stable to possess power transmission, control is convenient, and is simple in structure, easy to maintenance, weight is lighter, long service life, advantage such as maintenance cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure:
1, excavating gear 2, swing seat 3, holder
4, hydraulic jack 5, snubber block
The specific embodiment
As shown in Figure 1, the utility model is a kind of to be used for the mechanism that excavating gear swings, comprise excavating gear 1, swing seat 2, holder 3 and hydraulic jack 4, one end of the hinged swing seat 2 of one end of excavating gear 1, the other end and the holder 3 of swing seat 2 are hinged, are provided with 4, two hydraulic jacks 4 of two hydraulic jacks in the holder 3 and are the bilateral symmetry structure, the output of two hydraulic jacks 4 stretches out holder 3 respectively, and hinged respectively with the both sides of swing seat 2.
Preferably, this mechanism also comprises snubber block 5, and described snubber block 5 is installed on the holder 3 and is positioned at the left and right sides of swing seat 2 and holder 3 hinged places.
The course of work of this example: when excavating gear 1 need be swung, handle control valve left, left side hydraulic jack 4 is shunk, and at this moment, right side hydraulic jack 4 just stretches out, hydraulic jack 4 can change hydraulic pressure into mechanical energy, thereby has reached the effect that excavating gear 1 is swung left; Equally, reversible control will reach the effect that excavating gear 1 is swung to the right, and excavating gear 1 swing boils over, and reaches the effect of damping by damping rubber block 5.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
