Abstract

The utility model discloses a kind of tilting arm seat of wet shot trolley mechanical arm, to solve the problems, such as existing arm seat CRACKING ACCIDENT frequent occurrence due to intensity deficiency.By designing a kind of enclosed arm seat, including seat bottom, seat body, pitch arm mounting base and oil cylinder seat, feature is between pitch arm mounting base center and the line and seat bottom normal direction at seat body seat bottom engagement center to tilt pitch arm mounting base center to the direction far from oil cylinder seat center.The tilting design of arm seat can greatly improve the loading characteristic of arm seat, to improve the structural strength of arm seat.

Description

A kind of tilting arm seat of wet shot trolley mechanical arm

Technical field

The utility model relates to wet shot trolley technical fields, more particularly to a kind of tilting arm of wet shot trolley mechanical arm Seat.

Background technique

The arm seat of wet shot trolley mechanical arm carries the self weight and work dynamic loading of entire cantilever crane, is important carrying structure Part.During military service, strong dynamic loading leads to arm seat fatigue is opened frequent occurrence during severe working environment and whitewashing Accident is split, entire cantilever crane is even resulted in and collapses, seriously affects production operation safety.

Summary of the invention

In order to overcome the problems referred above, the utility model aim is the provision of a kind of arm seat structure type, to improve arm seat Loading characteristic, solve the problems, such as on the basis of not increasing cost existing arm seat because intensity deficiency due to crack frequent occurrence.

To achieve the above objectives, the present invention adopts the following technical solutions: by designing a kind of arm seat, including seat bottom, Seat body, pitch arm mounting base and oil cylinder seat are connected between component by welding, and pitch arm mounting base center is engaged with seat body seat bottom There are a slanted angles between the line and seat bottom normal direction at center, make pitch arm mounting base center to separate oil cylinder seat center Direction inclination.

The beneficial effects of the utility model are: the tilting by arm seat designs, the stress point position of arm seat is changed, greatly Width improves the ability that arm seat bears moment of flexure, to improve the intensity of arm seat.

Detailed description of the invention

Fig. 1 is the utility model structure three-dimensional schematic diagram.

Fig. 2 is the utility model right side view.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

Fig. 1 is the utility model structure three-dimensional schematic diagram, which forms closing symmetrical structure by plate product, specific special Sign includes seat bottom 1, seat body, pitch arm mounting base 6 and oil cylinder seat 7.Wherein seat body includes front vertical plate 2, back vertical plate 3,4 and of left risers Right risers 5.Pass through weld connection between seat body and seat bottom, pitch arm mounting base and seat body, oil cylinder seat and seat body.

Fig. 2 is the utility model right side view, when design, makes pitch arm mounting base center O₁With seat body seat bottom engagement center O₂Line O₁ O₂There are slanted angle θ between the normal direction of seat bottom；Front vertical plate 2 is designed to bending plate, upper part and 1 normal direction of seat bottom Between there are slanted angle α；There are slanted angle β between straight panel, with 1 normal direction of seat bottom for back vertical plate 3, make in pitch arm mounting base Heart O₁To far from oil cylinder seat center O₃Direction inclination, and pitch arm mounting base center O₁With oil cylinder seat center O₃Present 1 plane of bottom Projection be respectively at a body and seat bottom engagement center O₂Two sides.

It is preferred that angle theta as shown in Figure 2 is 10 °, α is 15 °, and β is 5 °, can effectively improve the bearing capacity of arm seat, while arm Seat is easy to process, produces and assembles.

Claims

1. a kind of tilting arm seat of wet shot trolley mechanical arm, including seat bottom, seat body, pitch arm mounting base and oil cylinder seat, seat body Including front vertical plate, back vertical plate, left risers and right risers, which is characterized in that during pitch arm mounting base center is engaged with seat body seat bottom There are a slanted angles between the line and seat bottom normal direction of the heart.

2. tilting arm seat according to claim 1, which is characterized in that deposited between the front and back vertical plate and seat bottom normal direction of seat body In certain angle, tilt pitch arm mounting base center to the direction far from oil cylinder seat center.
