Description

[0001] The present invention relates to an X-shaped outrigger for a vehicle,

The present invention relates to an outrigger technique having a support angle suitable for dispersion of a working load of a featured vehicle and a shape for preventing rollover of a featured vehicle at the time of breakage of a cylinder.

Specially designed vehicles are defined as cars equipped with special equipment and structures for carrying out specific tasks. They are classified as special vehicles in the Korean Automobile Control Act, and special-purpose freight cars in some transportation trucks. Special vehicles can be categorized as special purpose type, traction type, rescue type, and special type depending on the purpose.

Outriggers are mounted on the front, rear, left and right sides of a specially equipped vehicle frame to prevent the overturning of vehicles and special equipment when working on a specially designed vehicle, thereby securing the safety of the vehicle. Parts.

The outrigger is classified into H type and X type according to the support type and it is divided into electric type, hydraulic type and manual type in accordance with the driving type. Domestic specially manufactured vehicle manufacturers generally use a beam cylinder for adjusting the length of the left and right, It uses a lot of H type hydraulic outrigger equipped with a jack cylinder.

Basically, the outrigger acts as a supporter of the vehicle to prevent overturning of the vehicle in the left and right direction. In addition, it adjusts the length and height of each outrigger in the work space, not horizontal, do.

Outriggers must be able to withstand the loads of vehicles and special equipment, and they are important core parts directly connected with the safety of workers.

The use environment of the specially equipped car such as the complaints work done domestically is limited by the outrigger withdrawal length due to narrow alleys and poor road environment. This inadequate outrigger withdrawal is caused by a safety disaster such as vehicle overtaking due to a lack of support for the vehicle. The type of rollover of a specially designed vehicle is indicated by the use of an inappropriate outrigger pedestal, the outrigger and cylinder breakage, and the lack of outrigger support.

Conventional literature disclosing techniques related to the outrigger and outrigger device of a concrete pump car for a sophisticated work vehicle include Korean Registered Utility Model No. 20-0334447 (Nov. 29, 2003) and Korean Patent No. 10-0499973 ) Can be referred to.

Hereinafter, an X-shaped outrigger for a multi-purpose vehicle according to the present invention will be described with reference to Figs. 1 to 5. Fig.

The X-shaped outrigger 100 for a feature vehicle according to the present invention includes a frame module 110 fixed on a vehicle 10, a main bracket 120 rotatably mounted on the outer side of the frame module 110, An outrigger boom 130 rotatably coupled to the lower portion of the main bracket 120 so as to be rotatable in the upper and lower directions, a first cylinder 120 rotatably coupled to the upper portion of the main bracket 120 and the outrigger boom 130, A second cylinder part 150 rotatably coupled to the upper part of the main bracket 120 and a second cylinder part 150 rotatably coupled to the frame module 110 And a bearing module 160 for allowing relative rotation of the frame module 110 and the main bracket 120 on a coupling point between the main frame 110 and the main bracket 120.

The frame module 110 includes a pair of main frames 111 arranged at predetermined intervals along the longitudinal direction of the feature vehicle and a plurality of sub frames 113 arranged to connect the pair of main frames 111 .

The support body 115 is disposed at the center of the auxiliary frame 113 and the main bracket 120 is rotatably disposed on the end of the auxiliary frame 113 through the bearing module 160, The second cylinder part 150 connected between the main bracket 115 and the main bracket 120 pivots around the support body 115 in accordance with the rotation of the main bracket 120. Here, a separate bearing structure may be interposed between the support 115 and the second cylinder 150 to enable smooth rotation of the bearing.

The present invention simplifies adjustment of the outrigger boom (130) in the vertical direction through adjustment of the length of the first cylinder part (140). The first cylinder 140 rotatably coupled to the main bracket 120 and the outrigger boom 130 rotatably supports the outrigger boom 130 through a simple driving method that adjusts the overall length in the uniaxial direction. 130).

The outrigger boom 130 includes a rotary boom 131 that is directly coupled in a rotatable state on the main bracket 120, a rectilinear boom 133 that extends from the outside of the rotary boom 131, An intermediate member 135 fixed to the first cylinder 140 for engagement with the first cylinder 140 and a support member 137 rotatably coupled to the linear boom 133.

The outrigger boom 130 is configured such that a plurality of the outrigger booms 130 are arranged symmetrically on the frame module 110. That is, for example, two outrigger booms 130 on both sides of the frame module 110 may be installed in such a manner that mutual interference does not occur.

The main bracket 120 includes a first coupling part 123 formed on one side of the bracket body 121 to enable coupling with the bracket body 121 and the frame module 110, And a third coupling part 127 connected to the outrigger boom 130. The second coupling part 125 is connected to the outrigger boom 130, The second and third coupling members 125 and 127 are formed on the main bracket 120.

Referring to FIGS. 3 and 4, an operation process using the X-shaped outrigger for a featured vehicle according to the present invention will now be described.

The outrigger boom 130 enables adjustment of the vertical position of the first cylinder 140 by adjusting the length of the first cylinder 140. That is, by shortening the length of the first cylinder part 140 adjusted in the uniaxial direction, it is possible to rotate the linear boom 133 connected to the outer end of the first cylinder part 140 through the intermediate member 135 . In other words, the outrigger boom 130 rotatably coupled to the main bracket 120 through the third coupling hole 127 is capable of moving up and down by adjusting the length of the first cylinder 140 .

On the other hand, the adjustment of the angle along the front and rear of the outrigger boom 130 is made possible by adjusting the length of the second cylinder part 150.

The outrigger boom 130 mounted on the car is basically folded inside the frame module 110 when the length of the second cylinder part 150 is minimum. That is, when the outrigger boom 130 is not used, the outrigger boom 130 may be aligned along the longitudinal direction of the main frame 111.

When the outrigger boom 130 is used, the length of the second cylinder 150 is adjusted so that the center of the support 115 of the outrigger boom 130 is rotated. Thus, the unfolding angle of the outrigger boom 130 is arranged at various angles, for example, 45 degrees, 90 degrees, 135 degrees.

Hereinafter, an optimum design structure of an X-shaped out trigger according to the present invention will be verified with reference to FIG. 6 to FIG.

A method for verifying the optimal design structure of the out trigger in the present invention will be described by way of example.

First, referring to the structural analysis of FIG. 6, the outrigger design verification is performed so that the load can be distributed while the target load is set at 10 tons.

Pitch height 91.7 mm and supporting angle 45 degrees are analyzed.

The position where the load is applied acts as a uniform distribution load on the surface of the frame module 110, and the support member 137 rotatably coupled on the linear boom 133 is fixedly supported on the ground. The load applied shall be 10,000 kgf.

FIG. 7 shows an analysis result in which the pitch height is 91.7 mm and the spread angle of the out trigger is 45 degrees in order to verify the optimum design structure of the X-shaped outrigger according to the present invention.

The restraint and load conditions proceeded in the same way as the structural analysis of FIG. 6, and the maximum stress was found to be 179.82 MPa at the shaft portion of the outrigger and the safety factor of 4.3.

8 is an analysis result in which the pitch height is 91.7 mm and the spread angle of the out trigger is 90 degrees in order to verify the optimum design structure of the X-shaped outrigger according to the present invention.

The constraint and load conditions proceeded in the same manner as in the structural analysis of FIG. 6, and the maximum stress was 222.24 MPa at the shaft portion of the outrigger and the safety factor was about 3.5.
