Abstract

The utility model discloses a kind of loading arm, including rocking arm seat beam and its swing arm plate of both sides, it is characterised in that the rocking arm seat beam is made up of two pieces of risers between upper and lower two pieces of transverse slats and two pieces of horizontal versions, and two sides of transverse slat extend to the outside of portrait.Rocking arm seat beam on swing arm forms the box structure of closing by upper and lower two pieces of transverse slats and front and rear two pieces of riser butt welding；Transverse slat and the direct blanking of riser, without bevel again and bending, processing technology is simple, good welding performance.The utility model has the characteristics of simple in construction, good manufacturability, processing cost are low, bearing capacity is strong, service life is long.

Description

A kind of loading arm

Technical field

A kind of loading arm is the utility model is related to, belongs to technical field of engineering machinery.

Background technology

Loading arm is the important primary structure member of complete machine, and the quality of its structure directly affects loading machine performance.Mesh The swing arm of preceding in the market loading machine as shown in Figure 1-2, is mainly made up of, wherein rocking arm the swing arm plate 1 of rocking arm seat beam 2 and both sides Seat beam 2 is welded with rocking arm supporting plate 4 again by the butt welding of U-shaped board 3 of two pieces of bendings again.Structure need to open slope to U-shaped board 3 in this Mouthful and by opening bending, and butt welding is not easy to implement, and it is bad to be easily caused manufacturability, high processing costs.Meanwhile rocker arm bracket Beam 2 is limited by the structure of two pieces of butt welding of U-shaped board 3, and the weld seam between rocking arm seat beam 2 and swing arm plate 1 only has edge one to enclose, its Bearing capacity is bad, and the weld cracking between rocking arm seat beam 2 and swing arm plate 1 is easily caused under extreme operating condition.

The content of the invention

To be solved in the utility model is that existing loading arm processability of product structure is bad, high processing costs, carries energy The technical problem that power is bad, weld seam is easy to crack.

In order to solve the above problems, the utility model provides a kind of loading arm, including rocking arm seat beam and its both sides Swing arm plate, it is characterised in that the rocking arm seat beam is made up of two pieces of risers between upper and lower two pieces of transverse slats and two pieces of transverse slats, Two sides of transverse slat extend to the outside of riser.

Preferably, the transverse slat and the width of both sides swing arm plate junction are bigger than the width in the middle part of it, strengthen rocking arm seat beam Bearing capacity, the weld cracking of rocking arm seat beam is avoided, extend the service life of swing arm.

Rocking arm seat beam on swing arm forms the box-shaped knot of closing by upper and lower two pieces of transverse slats and front and rear two pieces of riser butt welding Structure；Transverse slat and the direct blanking of riser, without bevel again and bending, processing technology is simple, good welding performance.Wherein, it is horizontal Plate left and right ends respectively before and after locally extend, increase the fusion length between rocking arm seat beam and swing arm plate, improve stressing conditions.

The utility model uses said structure, has simple in construction, good manufacturability, processing cost is low, bearing capacity is strong, makes The characteristics of with long lifespan.

Embodiment

To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

Embodiment

As shown in Figure 3-4, it is a kind of structural representation of loading arm provided by the utility model, it includes rocker arm bracket Beam 2 and its swing arm plate 1 of both sides, the rocking arm seat beam 2 is by two pieces of risers 6 between upper and lower two pieces of transverse slats 5 and two pieces of transverse slats 5 Butt welding and the box structure for forming closing, two sides of transverse slat 5 extend to the outside of riser 6.Transverse slat 5 and riser 6 are direct Blanking, without bevel again and bending, processing technology is simple, good welding performance.As shown in figure 5, the transverse slat 5 and both sides The width of the junction of swing arm plate 1 is bigger than the width in the middle part of it, and this kind of structure adds the weld seam between rocking arm seat beam 2 and swing arm plate 1 Length, so as to improve the stressing conditions of rocking arm seat beam 2, strengthen bearing capacity, improve the service life of swing arm.

Claims (2)

1. a kind of loading arm, including rocking arm seat beam (2) and its swing arm plate (1) of both sides, it is characterised in that the rocker arm bracket Beam (2) is made up of two pieces of risers (6) between upper and lower two pieces of transverse slats (5) and two pieces of horizontal versions (5), and two sides of transverse slat (5) are prolonged Extend the outside of portrait (6).

2. loading arm as claimed in claim 1, it is characterised in that the transverse slat (5) and both sides swing arm plate (1) junction Width it is bigger than the width in the middle part of it.
