Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of attaching and detaching a chain integrated with a conveyor body in a conveyor device installed in a freight vehicle.

(b) Prior Art As shown in Fig. 4, a conveyor device installed in a conventional truck is provided with chains 01 and 01 between a pair of front and rear sprockets.
A conveyor body 02 is provided between the chains 01 and 01, and a floor plate 03 is provided below the conveyor body 02 to cover the entire lower surface of the conveyor device. In addition to providing the side plates 05, 05 of the mold, the side plates 05, 05
Protective covers 06, 06 are bolted to the upper horizontal surfaces 05a, 05a of the conveyor body 02 to prevent the powder from spilling to the left and right sides of the conveyor body 02 when powder and granules are loaded.
The lower ends of the protective covers 06, 06 were placed close to the upper surface of both ends of the conveyor body 02.

(c) Problems to be Solved by the Invention Due to the above structure, when the chain is worn out and replaced, the protective cover must be removed each time, which is extremely troublesome.

(d) Means for solving the problems The present invention was made to solve the above problems, and includes a pair of front and rear sprockets.
A conveyor device is provided with a pair of left and right chains driven by an appropriate drive means between the pair of sprockets, and a conveyor body is provided between the pair of chains, and the conveyor device is mounted on a vehicle body via a pair of left and right side plates. In a freight vehicle with a motor vehicle, a protective cover is provided hanging from the upper part of the pair of left and right side plates, the lower end of which is close to the upper surface of both ends of the conveyor body, and a floor plate is further provided on the side plate to cover the entire lower surface of the conveyor device, and this floor plate is provided. An insertion opening with a width between the chains that allows insertion of a chain integrated with the conveyor body is provided at the rear of the conveyor, and an opening/closing lid is provided to open and close this insertion opening.

(e) Embodiment Hereinafter, an embodiment will be explained based on the drawings. Fig. 1 is a side view of a freight car equipped with the conveyor device of the present invention, and 1 shows a pair of left and right side plates 1 having a box-shaped cross section.
This is a van-shaped cargo box mounted on the vehicle body 2 via terminals 6 and 16, and side walls 15 and 15 are provided on both sides of the cargo box 1.
However, a door 3 is provided at the rear, and a conveyor device 5 for transporting cargo is provided inside the side plates 16, 16.
is provided. To explain the conveyor device 5 below, 6, 6 are a pair of left and right front sprockets provided at the front of the side plates 16, 16, and 7, 7 are the side plates 1.
A pair of left and right rear sprockets provided at the rear of parts 6 and 16.
A pair of left and right endless chains 8, 8 are spanned between them, and a conveyor body 9 on which cargo can be loaded is provided between the left and right chains 8, 8.

The conveyor main body 9 has metal slats 10...
and shielding members 11 made of vinyl chloride are provided alternately to make it possible to transfer the powder and granular material as well as to move it in an arc.

A stand 12 is provided at the front end of the conveyor body 9 to prevent cargo from collapsing, and this stand 12 is supported by a horizontal stand 13 having a predetermined width. , 8, so that it moves together with the movement of the conveyor main body 9.

Upper horizontal surfaces 16a, 16 of the side plates 16, 16
Protective covers 24, 24 are installed vertically at the ends of a to prevent the powder from spilling to the left and right sides of the conveyor body 9 when the powder is loaded.
The lower end portions of the conveyor body 9 are located close to the upper surface of both end portions of the conveyor body 9.

Reference numeral 4 denotes a floor plate provided below the conveyor device 5 so as to cover the entire lower surface of the conveyor device 5. By providing this floor plate 4 between the side plates 16 and 16, mud etc. that are splashed up during running do not get on the conveyor device 5. It's like this.

Reference numeral 17 denotes an insertion port below the rear sprockets 7, 7 into which chains 8, 8 integral with the conveyor body can be inserted;
It has a width in between.

The insertion port 17 is provided with an opening/closing lid 23 for opening and closing the insertion port 17, and is held closed by screws 18.

Note that 19 is a rear cover provided at the rear close to the rear sprockets 7, 7, and 20 is a rail fixed in the front-rear direction at appropriate intervals on the pedestal 14 provided between the side plates 16, 16. , 21
... is provided inside the rail 20..., and the conveyor body 9
22, 22 are girders that are fixed to the frames 14 and support the chains 8, 8 that have moved upward.

The present invention has the above-mentioned structure, and its operation will now be described. First, when unloading the cargo on the conveyor main body 9, the chains 8, 8 are moved clockwise from the state shown in FIG. 1 by appropriate driving means.

Since the rack 12 also moves rearward accordingly, the cargo can be unloaded sequentially from the rear of the cargo box 1. When loading cargo, the tailgate 12 moves the chains 8, 8 counterclockwise from the rearmost position.

Along with this, the support stand 12 also moves forward, so that the conveyor main body 9 also moves forward, and the goods can be sequentially loaded onto the conveyor main body 9.

By the way, when installing the chains 8, 8 with the conveyor body 9 attached, first remove the screws 18, open the opening/closing lid 23, and insert one end of the chains 8, 8, which are integral with the conveyor body 9, through the insertion opening 17. Then, send it upward between the rear sprockets 7, 7 and the rear cover 19, apply it to the rear sprockets 7, 7, rotate the rear sprockets 7, 7 counterclockwise by appropriate means, and move the chains 8, 8 to the rear sprocket 7. , 7 upward.

Next, attach strings to the ends of chains 8, 8,
While turning the rear sprockets 7, 7, pull the string to slide it over the girders 22, 22 and apply one end of the chains 8, 8 to the front sprockets 6, 6.

Turn the string further and pull it backwards until one end of the chains 8, 8 reaches the position of the rear sprocket 7, 7, then remove the string and connect one end of the chains 8, 8 to the other end to form an endless chain. Let's say 8,8.

Next, when the chains 8, 8 are worn out and need to be replaced, open the opening/closing lid 23, remove the connecting part of the chains 8, 8 from the insertion port 17, and insert one end of the chain integral with the conveyor body 9 into the insertion port 17. Pull out the entire chain 8, 8 with more tension.

When installing new chains 8, 8, the same procedure as in the above-mentioned assembly may be used.

(f) Effects of the Invention As described above, the present invention provides an insertion opening for inserting a chain integrated with the conveyor main body at the rear of the floor plate, and allows the chain to be taken in and out from this insertion opening. You can easily do this without having to remove the protective cover each time.
