It shows how to tighten using screws such as bolts and nuts.

Hereinafter, a detailed embodiment of the present invention will be described.

All members to be used in the present invention can be easily carried out by using a steel pipe pipe, a square tube, an angle, a flat iron, etc., which are general industrial structural materials, and a person having basic knowledge about mechanical engineering can only use the drawings illustrated in the present invention. Since the report can be easily performed, the method of combining and integrating each member in the method of the present invention will not be described any further.

Stalls 11, crossbars 12, intermediate fasteners 14, upper fasteners 13, and lower fasteners are columns having ladder-shaped members having a length exceeding the maximum height of the loaded cargo on the left and right sides of the truck. The vertical column 10 composed of 15) may be configured as a structure, such as a ladder of H-shape as shown in FIG. This vertical column serves as a support for the wall-covered cargo cover that prevents cargo from being spilled out of the cargo box and as a support for the foundation of lifting equipment such as chain blocks or winches used for loading and unloading cargo. It shall be designed to have strength as a member against load. All members constituting the vertical column 10 illustrated in FIG. 3 may use any form of industrial structural material in solid form, such as high strength steel or alloy steel based on iron, aluminum, or engineering plastic, but is convenient in manufacturing a product. In consideration of the use of a general structural steel having good weldability and good price characteristics, it is the most easily selected material.

The lower end of the vertical column is erected on the bottom of the loading box, and installed in contact with the wall of the loading box side of the left and right plates, the means for ensuring that the lower end of the vertical column is firmly fixed to the bottom of the loading box will be in charge of the holder 50. .

Beam horizontal member 21, beam inclined member 22, repair fabric 23, beam vertical fastening member 24 in order to receive the load required when loading and unloading the cargo by interconnecting the upper and lower ends of the vertical column , Horizontal beams 20 in which the upper beam fastener 25, the beam bearing 26, the upper beam floor material 27, the length fastener 28 is formed in a pair of front and rear of the truck is a vertical column 10 The upper fastener 13 at the top and the beam vertical fastener 24 of the horizontal beam are integrated by a pair of prefabricated fastening means. The way in which the two horizontal beams in the front and rear of the truck are vertically fastened to the top of two vertical pillars 10 one by one in the left and right directions of the truck can be easily performed by looking at the photograph shown in (2) of FIG. 13. .

It is used when loading and unloading cargo by integrating the load body 31, the lifting position stator 32, the end stator 33, and the load horizontal fastening member 34 by using the pipe-shaped member as the main member on the horizontal upper end. The load beam 30 serving as the support point of the lifting device has a rod-like structure as shown in FIG. 5, connecting the upper ends of the horizontal beams 20 one by one in front and rear of the truck by hinges. The structure in which the load beams are interconnected with the horizontal beams 20 can be easily performed by looking at (1) and (2) of FIG. 13.

This load beam has two load horizontal fasteners 34, which are combined with the upper beam fasteners 25 of the horizontal beams 20 to make hinges. Two load horizontal fasteners 34 are required. 5, there is only one load horizontal fastener 34 notation, but the left end of the load body 31 is shown on the left end of the load body 31 (in the direction in which the practitioner looks at the drawing of the present patent, but actually the front side of the truck). The hole is this load horizontal fastener 34 as well.

The lifting position stator 32 is made of a small solid material such as cutting the round bar or cutting a pipe so that the length stator does not slide on the load body to be fixed to the length stator at an arbitrary position determined by the user. It can be arranged at regular intervals in the and fixed by the integration method such as welding. The end stator may be integrated with a method such as welding a small round bar to protrude a tip such that the length stator does not deviate from the end position of the load body anymore. When the load beam is loaded and unloaded, the weight of the cargo to be handled is at the position of the length stator, and the weight of the load is applied to the beam upper fastening member of the horizontal beam. Since the concentrated load is in operation at the point, the design should be able to endure the strength and the size and material of the relevant members such as the load body should be selected.

In order to connect the load beams and the horizontal beams to each other in a truss structure, the truss structure can be dismantled so that the position of the load beams is lowered when the vehicle moves and the position of the load beams is increased when the cargo is unloaded. The length 90 is composed of an upper length body 91, a lower length body 92, a bottom length body 93, a length body connector 94, a front connector 95 and a rear connector 96. As a connecting member for connecting the horizontal beam in the axle direction, it should be carried out as illustrated in FIG.

Since the horizontal beam includes a triangular shape or a triangular structure, a hinge is formed at the upper part of the horizontal beam at the front and a lower part of the horizontal beam at the rear so that the neighboring triangular structure is not deformed even under external force. You will build a truss structure. However, since the truck must be moved after the loading and unloading work is completed, the position of the load beam is lowered during the movement to facilitate the movement of the truck. Therefore, the load beam and the horizontal beam are integrated in order to lower the height of the load beam. Since one member of the length beam is rotated, the total length of the upper length body 91 and the lower length body 92 of the length beam 90 must be varied depending on the angle of the horizontal beam when the horizontal beam is rotated. Should be taken. And, when working up and down work, as the horizontal beam should be in a vertical state with the ground as shown in [Fig. 1], [Fig. 2] or [Fig. 13], the upper length body and the lower length body of the length beam according to this shape The length of the body connector 94 should be configured to fix the total length of the. For this purpose, various means can be mobilized. If the upper length body and the lower length body have different diameters on the pipes having the same cross-section, the upper length body and the lower length body wrap each other and change the length. If you make a hole in both ends and align the holes to each other and then insert the pins, the length is converted and provided with a variable length structure that is fixed at a certain length. Alternatively, it is a member having a female screw on one side and a male screw on the other side, so that the male screw portion or the female screw portion can be rotated to form a variable length member.

As illustrated in FIG. 6, the upper length body 91 and the lower length body 92 are fixed in length by the length body connector 94, and the front connector with the upper portion of the horizontal beam 20 in front. (95) is fastened by a hinge, the lower end of the rear horizontal beam is composed of a hinge by the rear connector, the bottom length body 93 connecting the lower ends of the horizontal beam in the front and rear using the prefabricated fastening means Just do it. The member of the length beam may be implemented by using an industrial pipe or a pipe.

When the loading and unloading of the cargo is completed, the load beam should be lowered to move the truck to improve the safety of the vehicle and look good. To this end, the height of the load beam is to be lowered by loosening the fixed state of the length body connector and rotating the horizontal beam. This structure is shown in detail in FIG.

The vertical fastener should be a structure capable of fastening the vertical fastener at any position of the vertical pole 11 of the vertical column. The vertical fastener should be a structure that can wrap or unwind the outside of the vertical pole, but when the vertical pole is adopted as a pipe, You can use clamps as shown in [8]. This stand is fitted to the vertical pole of the vertical post and the other end of the truck's loading box when connected to the truck's loading box rope stator, which is welded at regular intervals to secure the rope on all commercial trucks. The vertical column can be firmly fastened to any point. In general, the size of the left side plate and the right side plate is different according to the capacity and the production company, and the distance between the loading box rope stator and the vertical column is variable because the vertical column is placed at an arbitrary position. Even in such a situation, in order to securely fasten the loading box rope stator and the vertical column, a necessity for a structure in which the distance between the vertical fastener 54 and the side plate fastener 55 can be adjusted is required, which is a shape of the variable length structure. You will be asked. In the present invention, as shown in Fig. 8 is fastened to a vertical fastener (54) that can hold and fix the vertical column at any position of the vertical column at one end, the other end is fastened to the loading box rope stator, the upper fixing body 51 The lower fixing body 52 is integrated with these, and the upper fixing body and the lower fixing body may be connected by screws to adjust the length. (1) and (2) of FIG. 8 show various embodiments of the holder 50 according to the above description. Vertical fasteners 54 and the upper fixed body 51, the side plate fastener 55 and the lower fixed body 52 should be constructed a hinge form that can be rotated, but hinge the structure of both ends according to the hole size of the side plate fastener It may not be in prison.
