Abstract

PROBLEM TO BE SOLVED: To surely install a side face cover body with ease by forming a pair of frames on both sides into long thin rectangular frame shapes respectively, forming an upper horizontal member and a lower horizontal member of the frame by lightweight channel steel into U- shapes in the cross sections, and installing the side face cover body with a U-shaped cross section around side wall parts in the opposed upper and lower horizontal members. SOLUTION: A belt conveyor 1 is constructed of a pair of both side long thin rectangular frame type frames 2, 3 in which an upper horizontal member 4 and a lower horizontal member 5 are respectively made of lightweight channel shape steels and provided with U-shaped cross sections. A vertical member 6 made of a lightweight channel shape steel and a side face cover installing member 7 are arranged at the predetermined interval between the upper horizontal member 4 and the lower horizontal member 5. A pair of both side cover bodies 8, each of which is drawn by bending its both side edges so as to be provided with a U-shaped cross section and provided with the predetermined length, are hooked by fitting their bending lines around the opposed side wall parts 9, 10 in the upper horizontal member 4 and the lower horizontal member 5 so as to be installed in the mounting body 7 via a set screw 11. The side face cover body 8 can be easily drawn, while a lightweight channel shape steel is used for the upper member 4 and the lower member 5, so that the frame can be produced at a low cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor frame, and more particularly to a belt conveyor frame to which a side cover body can be easily attached.

[0002]

2. Description of the Related Art A conventional belt conveyor has a head pulley and a tail pulley at both ends of a pair of double-sided frames having a required length. The head pulley is rotatably attached and
It is known that an endless drive belt is wound between tail pulleys so as to run freely. By the way, recently, from the viewpoint of safety in use, it has been proposed to attach a cover body formed by sheet metal processing to a required shape on both side surfaces and a bottom surface of a belt conveyor. However, since such a cover body must be appropriately sheet-metal processed in accordance with the outer surface shape of the frame, not only is the work extremely laborious and time-consuming, but also the mounting work on the frame is very troublesome. It was annoying.

According to the present invention, the conventional problems are solved, and the upper and lower lateral members constituting the frames on both sides are formed in a U-shaped cross section with light groove steel, and the side wall portions which are vertically opposed to each other are formed. Side cover with a U-shaped cross section that can be easily used for sheet metal processing
An object of the present invention is to provide a frame for a belt conveyor, which can be attached to a body very easily and reliably.

[0004]

SUMMARY OF THE INVENTION That is, according to the present invention, a pair of frames 2.3 on both sides constituting the belt conveyor 1 are formed in the shape of an elongated rectangular frame. The upper and lower lateral members 4 and 5 are each formed of light channel steel in a U-shaped cross-section, and side walls 9 and 10 of the upper and lower lateral members 4 and 5 facing each other vertically face each other. The gist of the present invention is that the cover body 8 is configured to be hooked and externally fitted.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Since the upper and lower horizontal members 4 and 5, which respectively constitute the frames 2 and 3 on both sides, are formed in a U-shaped cross section by light channel steel, side wall portions which are vertically opposed to each other. 9.1
The side cover body 8 having a U-shaped cross section can be hooked and attached to the outside by 0, and the attaching work can be performed very easily and surely. Moreover, since the side cover body 8 can use a very simple U-shaped cross section, not only the sheet metal processing can be performed very easily, but also the upper and lower lateral members 4 and 5 are commercially available. Combined with the use of the light channel steel of the above, it is possible to manufacture the frames 2 and 3 at an extremely low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 designates a belt conveyor having a required length, and 2.3 designates a pair of elongated rectangular frame-shaped frames constituting the belt conveyor 1, and upper and lower lateral members 4 on both sides of the frames 2.3. Each of 5 is made of light channel steel with a U-shaped cross section. Reference numeral 6 is a vertical member made of light channel steel which is erected at a predetermined interval between the upper and lower horizontal members 4 and 5, and 7 is a side cover which is erected at a predetermined interval between the upper and lower horizontal members 4 and 5. The mounting member 8 for use is a pair of side cover bodies on both sides having a required length, which are formed by sheet metal working into a flat U-shaped cross section by bending both side edges. Side wall portions 9 of the upper and lower lateral members 4 and 5 whose bent edges face each other vertically
It is externally fitted to 10 to be hooked, and is also fastened to the mounting member 7 via a set screw 11.

Reference numerals 12 and 13 denote a head pulley and a tail pulley which are rotatably mounted on both ends of the frames 2 and 3, respectively, and a reference numeral 14 denotes the head pulley 12 and the tail pulley 13. An endless drive belt wound freely between the motors, 15 is a motor installed on both sides of the frames 2 and 3 via a mounting plate 16 so as to rotate the head pulley 12,
Reference numeral 18 designates an upper receiver and a lower receiver of an endless drive belt 14 which is erected at a predetermined interval on the upper and lower portions of both side frames 2 and 3.
Are skirts mounted inwardly on the upper lateral members 4 of the two-side frames 2 and 3, and 20 is a bottom cover body mounted between the lower lateral members 5 in a erected manner.

The embodiment constructed as described above has a motor 1
5, the head pulley 12 is rotatably operated and the endless drive belt 14 is caused to travel in a predetermined direction to convey a required object to be conveyed. Further, at the time of such conveyance, the side surfaces of the both side frames 2 and 3 are covered by the side surface cover bodies 8 in a closed manner, so that the safety is very high.

[0009]

As described above, according to the present invention, the upper and lower lateral members 4 and 5 forming the frames 2 and 3 on both sides of the rectangular frame are made of light groove steel and have a U-shaped cross section. Since it is formed in the above, the side cover body 8 having a U-shaped cross section can be extremely easily fitted to the outside by utilizing the side wall portions 9 and 10 which face each other vertically.
Moreover, it can be securely attached. Moreover, since the side cover body 8 can be used by adopting an extremely simple U-shaped cross section as compared with the conventional example, not only the sheet metal processing can be performed extremely easily, but also the upper and lower parts can be processed. It can be manufactured at a very low cost in combination with the use of commercially available light channel steel as the lateral members 4 and 5.
