Description

度が等しければ直進する。また（∠Ｎ，ＳＱ，Ｌ）が角０度であれば直進する。ピストンの伸縮ストロークの伸びを長く作動すると回動角度は順次大きくなるものの過大な角度になるとトラクターは前進牽引困難となりうるため最大角を検討し選択する。
台車ステアリング制御装置はトラクターのハンドル回転と同時に電気信号によりコンピューター制御し本体フレームに内蔵する油圧ポンプの作動で油圧力、量、バルブ操作を選択し走行回動台車のタイヤの路面との摩擦係数も検討して舵取り角度を決定する。また油圧ポンプのバルブを手動で切り換える補助装置を装着し安全を期す構造とする。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a trailer for transporting long load cargo.
[0002]
[Prior art]
In general, a truck pole trailer, a tractor pole trailer, or the like is used for road transportation of heavy loads and long loads.
[0003]
Problems to be Solved by the Invention
The loading part of the towed pole trailer is located at the same high position as the loading part of the tractor, which is the towing vehicle, and the long cargo is supported by the two points of the front and rear vehicles. Below is a long space high above the ground. For this reason, while transporting long cargo by road on a tractor pole trailer, vehicles or bicycles running in parallel with other lanes in the middle of the cargo or in the large space below may jump in or jump in, or even enter humans and become involved in a serious accident. In many cases, the first issue is the vehicle structure for preventing accidents in long cargo transportation.
[0004]
Further, since the load is a single item, the length is 15 m to 20 m or more, and the weight is light, it is a bulk stack, so that a plurality of packages are stacked in several stages. In this case, the loading platform is not a semi-trailer type flat (flat) loading platform, so the pitching and rolling action is continuously and repeatedly performed at the support points of the front vehicle tractor and the rear vehicle pole trailer's loading platform, and the load itself is biased. In reality, twisting and kinking work to cause abnormalities in the retaining tool, loosen or break, causing falls and rollover, resulting in unstable running. Although it was a problem that had been a concern for a long time, the pole trailer system finally decided not to approve the road operation of new manufacturing vehicles on the road, and challenged the means of structural modification of vehicles to increase the safety of long cargo transportation Let it be 2.
[0005]
Remodeling the semi-trailer for long-haul cargo transportation by recognizing the re-conversion of expensive vehicles from the viewpoint of resource recycling from the fact that the three-axle semi-trailer is scrapped and scrapped when the three-axle semi-trailer is scrapped The third problem is a structural change means to be diverted.
[Means for Solving the Problems]
As a countermeasure 1 for issues 1 to 3, the frame stamping number of the semi-trailer of the existing existing vehicle or a scrapped standard relaxed vehicle (having a loading capacity of 36 tons or more and a flat axle vehicle) is used as it is to the rear of the vehicle. This is a means to solve the problem by changing the structure and remodeling. The pitch of the I-shaped steel frame is about 700 mm, and the left and right two frames are cut into two parts along the line of the front axle front (e) side surfaces 1, 2, and 3 of the three-axis vehicle body, and cut to form an upper body frame portion ( Left, 1, 2, 3) (right, 4, 5, 6, etc.) and lower traveling axle parts (a, b, c, d, e, f) Separated into b, c, d, and e. B, c, d, and e are welded with reinforced steel and used as a floor or turn plate for a coupler or boss on the central axle (no need for pitching and rolling functions). ), And keep the plane at the same height as the floor steel plate.
[0007]
Welded reinforced steel to the lower 2,3,4,5 of the upper body part frame, and reinforced each part as a ceiling plate or slide plate to maintain the same strength as gooseneck, and in the center King pin (R) or set pin (SQ) is fixed, and it is connected to a flat coupler (K) or boss (SQ) as a shaft base to prevent left and right swing due to the excellent stability of the three-axis traveling vehicle body. . The three-axle truck that freely rotates around P or Q is driven by the tractor (I) together with the upper body frame (II) to be a towed vehicle (III). When the coupler is not installed, insert the shaft pin (S), set pin (S), etc. from the boss at point O or R of the main body frame and fix it with a strong nut from inside the upper main body, so that it can be easily detached. .
[0008]
The length of the semi-trailer (flat cargo bed) is about 12M. Coupler (K) of truck is connected with kingpin P for loading regular size cargo, and coupler (K) is jointly set with kingpin Q for loading long cargo of 15M or more. . In the case of loading very long cargo such as rails, cut two I-section steels (frames J and M) at the center of the semi-trailer frame (I, U), and place a box-type frame ( 、 こ フ レ ー ム 差 差 差 差 差. The front I is fixed, and the I-beam on the rear is freely expandable and contractable inside the box-shaped frame. By examining the shared load according to the length of the long cargo, a predetermined point is selected and firmly fixed and easily attached and detached. And a structure that is possible. By means of reinforcing the left and right box frames to each other with beams or the like and extending the entire frame length, it is possible to safely transport a long load of 24 m or more.
[0009]
When the connecting coupler (K) of the traveling vehicle is disengaged and moved from the point O to the point R, a manual jack with a roller (j) is installed at the center left and right of the vehicle and the main body frame is raised to a position exceeding the height of the kingpin. Only the bogie brake operates to move the tractor forward, lower the jack behind point R, re-advance and connect. When a coupler or a kingpin is not used, a shaft pin or a set pin is used to insert and use a strong nut or the like to easily fix and detach the structure. In this case, a roller jack becomes unnecessary. High-pressure hydraulic hoses and air hoses are also equipped with easy-detachable valves, and folding auxiliary side bumpers are attached to the left and right to prevent jumping.
[0010]
As for the steering device, a left hydraulic cylinder (E, G) and a right hydraulic cylinder (F, H) with the left (E) and right (F) fulcrums as the fulcrum of the three-axis traveling trolley are installed inward and inward. The end (V1) of (EG) is fixedly connected to the set pin (S1) inserted from the boss (X1) of the body frame (II) J (right). Similarly, the end V2 of the pistons F and H is connected to the boss X2 of the frame M. The structure is such that it can be fixed to the set pin S2 to be inserted, act as a starting point, and can be easily detached. The bogie frames E (left) and F (right) with the set pins (S1, S2) as the operating base point rotate left and right with the kingpin SQ as an axis by expansion and contraction of the cylinder piston. For example, if the tractor handle is turned to the right in the traveling direction, the piston (V1) of the bogie left cylinder (EG) is extended, and the bogie frames E and F turn to the left around the kingpin SQ with the set pin (S1) as a base point. Moving and traveling, the inner wheel difference between the tractor and trailer is reduced and adjusted to improve the cornering performance on narrow turns and other roads to enable stable traveling. Therefore, the rotation of the bogie is such that G, V1, H, V2, and C2 are on the concentric circumference with SQ as the center axis base,

If equal, go straight. If (∠N, SQ, L) is at 0 degree, the vehicle goes straight. When the extension stroke of the piston is extended, the rotation angle gradually increases, but if the rotation angle becomes excessive, the tractor may have difficulty pulling forward. Therefore, the maximum angle is examined and selected.
The trolley steering controller controls the computer with an electric signal simultaneously with the rotation of the tractor handle, selects the hydraulic pressure, amount and valve operation by operating the hydraulic pump built into the main frame, and also determines the coefficient of friction of the traveling rotating trolley tire with the road surface. Examine and determine the steering angle. An auxiliary device for manually switching the valve of the hydraulic pump is installed to ensure safety.
