Abstract

The utility model discloses a kind of monoblock type double track telescopic arm, it is characterised in that：Including two telescopic arms, the telescopic arm includes fixed arm and the extension arm being embedded in fixed arm, connected between described two fixed arms by fixed arm crossbeam, connected between described two extension arms by extension arm crossbeam, telescopic oil cylinder is provided between the fixed arm crossbeam and extension arm crossbeam, the end of the extension arm and the end of fixed arm are equipped with a lifting ear, and the fixed arm side is provided with one side lifting ear.The utility model uses integral telescopic pipe, reduces welding portion, the intensity of increase handling large arm, relatively low handling risk.

Description

A kind of monoblock type double track telescopic arm

Technical field

The utility model belongs to handling facilities, and in particular to a kind of monoblock type double track telescopic arm.

Background technology

With industrial expansions such as building installation engineering and national defence, telescopic arm structure obtains telescopic boom device in engineering practice Extensive utilization is arrived.It the advantage is that:It has larger bearing capacity when by a small margin, under the load situation of permission again With longer operation distance and higher operation height.Telescopic arm structure is used for engineering truck or other means of transports at present On.Telescopic arm is influenceed mainly for by its inherent structure, and generally existing swing arm or dipper retractility are limited, and causes it to excavate deep Degree is corresponding be affected to.

Utility model content

Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of monoblock type double track and stretched Contracting arm.

Technical scheme：In order to solve the above technical problems, a kind of monoblock type double track telescopic arm provided by the utility model, including Two telescopic arms, the telescopic arm include fixed arm and the extension arm that is embedded in fixed arm, between described two fixed arms Connected by fixed arm crossbeam, connected between described two extension arms by extension arm crossbeam, the fixed arm crossbeam is with extending Telescopic oil cylinder is provided between arm crossbeam, the end of the extension arm and the end of fixed arm are equipped with a lifting ear, the fixation Arm side is provided with one side lifting ear.

Further, it is connected between the fixed arm crossbeam and fixed arm by welding manner.

Further, it is connected between the extension arm crossbeam and extension arm by welding manner.

Further, connected between telescopic oil cylinder and the fixed arm crossbeam, extension arm crossbeam by pin.

Beneficial effect：The utility model in terms of existing technologies, has following characteristics：

1）, the utility model use integral telescopic pipe, reduce welding portion, the intensity of increase handling large arm, relatively low handling Risk.

2）, the utility model it is easy for installation, without welding, that is, tear open and use, reduce workload, reduce cost, avoid welding Reason causes telescoping tube to be broken with steel plate large arm.（Prior art be square tubes soldering on steel plate, be overall square tube now）, subtract The deadweight of light complete equipment, reduces the oil consumption of loading machine, and by double track telescopic arm can greatly increase maximum load-carrying capacity and Retractility.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is side structure schematic diagram of the present utility model.

Wherein：1. lift the side of 6 fixed arm of ear 2 extension arm crossbeam, 3 extension arm, 4 telescopic oil cylinder, 5 fixed arm crossbeam 7 Lift ear.

Embodiment

The utility model is further described below in conjunction with the accompanying drawings.

As shown in Figure 1 and 2, a kind of monoblock type double track telescopic arm, including two telescopic arms, the telescopic arm include fixed arm 6 And the extension arm 3 in fixed arm 6 is embedded in, and connected between described two fixed arms 6 by fixed arm crossbeam 5, it is described two Connected between extension arm 3 by extension arm crossbeam 2, telescopic oil cylinder 4 be provided between the fixed arm crossbeam 5 and extension arm crossbeam 2, The end of the extension arm 3 and the end of fixed arm 6 are equipped with a lifting ear 1, and the side of fixed arm 6 is provided with one side lifting ear 7.It is connected between the fixed arm crossbeam 5 and fixed arm 6 by welding manner.The extension arm crossbeam 2 and extension arm 3 it Between be connected by welding manner.Connected between the telescopic oil cylinder 4 and fixed arm crossbeam 5, extension arm crossbeam 2 by pin Connect.

In the present embodiment, after the tipping bucket of loading machine is pulled down, fixed arm can be mounted directly by jointed shaft and lifting ear Onboard, the oil inlet and oil return road for controlling tipping bucket is directly installed on telescopic oil cylinder, you can realize Telescopic；Become small-sized lifting Machinery.

Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
