Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a belt conveyor cover mounting tool for fixing a connection type FRP belt conveyor cover (hereinafter abbreviated as a belt conveyor cover) covering a belt conveyor to a belt conveyor support frame.

[0002]

[Prior art]

 Belt conveyors are used both indoors and outdoors.In particular, the belt conveyors are used to transport coal for fuel at thermal power plants and gravel at quarry sites, especially outdoors, to protect the belt conveyor itself. In addition, a belt conveyor cover that covers the entire belt conveyor has been installed to prevent wetting of conveyed items due to rain and pollution such as noise and dust scattering. As a means for fixing the belt conveyor cover, when the belt conveyor cover is damaged, it must be partially repaired or replaced, so that it is required to have good handleability at the time of replacement. However, with conventional belt conveyor cover fixing means that use bolts and nuts, the fixing work is troublesome, the bolts and nuts do not come off due to rust, and the belt conveyor cover is fixed with a through hole. Since the method causes a crack to be generated around the hole due to vibration, etc., currently, as described in JP-B-55-24012, etc., it has a shaft portion that linearly extends from one end of a bar material such as iron, An arch-shaped belt conveyor using a fastener having a plurality of bent portions extending from the shaft portion and having a holding gap formed between the bent portions and a guide portion that is the other end of the bar extending from the bending portions. Attach the stopper so that it can rotate around the shaft, to the mounting plate with the fixing legs that extend outward along both edges of the cover fixed along both sides of the belt conveyor support frame, The pinch of this stopper The mounting plate and the fixing leg are fitted in the space, and the side edge of the fixing leg is clamped and pressed. The shaft hole bored on the rotation track surface of the stopper is manufactured. In consideration of cost, a structure is adopted in which an inexpensive resin pin is inserted to prevent the stopper from rotating in the direction of releasing the clamp.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional belt conveyor cover mounting device has a structure in which the fixing leg portion of the belt conveyor cover and the mounting plate are clamped, and the stopper is inadvertently rotated in the direction of releasing the clamping. The resin pin to prevent is lightweight, so it will come off due to vibration of the belt conveyor or the cover being blown by the wind, etc., and the stopper of the belt conveyor cover will come off, resulting in the belt conveyor cover coming off or blowing away. In addition to being extremely dangerous, there is a risk of diffusing harmful substances such as dust and noise, and frequent patrol monitoring is required, which increases maintenance costs such as safety confirmation. There were challenges.

According to the present invention, a stopper (hereinafter, referred to as a rotation prevention stopper) that prevents the stopper of the belt conveyor cover from being inadvertently rotated in the direction to release the nipping does not come out accidentally. By doing so, the belt conveyor cover can be fixed stably for a long period of time, and even when the belt conveyor cover is replaced, it can be removed and installed without trouble, and there is no deterioration in handleability due to changes over time, safety confirmation, etc. The challenge is to provide a belt conveyor cover attachment that can ensure the economic efficiency of maintenance costs.

[0005]

[Means for Solving the Problems]

 The belt conveyor cover attachment according to the present invention is to solve the above-mentioned problems, and has a shaft portion (17) linearly extending from one end of a bar, and a bent portion continuous from the shaft portion (17). Of the arch, using a stopper (11) that forms a sandwiching interval (M) between the bent portion and the interior (15) which is the other end of the rod connected from the bent portion. Mounting plate (54) with fixing legs (52) extending outward along both edges of the belt conveyor cover main body (51) fixed to both sides of the belt conveyor support frame (41). Put it on top, and bore the shaft holes (55) and (56) in the mounting plate (54), and rotate the shaft portion (17) of the stopper (11) in the shaft hole (55). The mounting plate (54) can be freely inserted and rotated around the shaft portion (17) of the stopper (11) so as to pass through the position of the shaft hole (56) and within the holding space (M). Also, by sandwiching the fixing leg portion (52), the shaft hole (56) A belt conveyor cover mounting device having a rod-shaped rotation preventing stopper (31) inserted therein, wherein the rotation preventing stopper (31) is provided with a protrusion (32) or a step (37) near the head. A belt conveyor cover mounting tool, characterized in that the belt conveyor cover mounting member is provided as a metal rod having a maximum diameter larger than that of the shaft hole (56).

The material of the bar material used for the stopper (11) and the rotation prevention stopper (31) is iron, etc. If higher corrosion resistance is required, stainless steel, etc. is used.

Further, the means for preventing the rotation prevention stopper (31) from coming off from the shaft hole (56) formed on the mounting plate (54) is a means for forming a protrusion (32) or a step. There is a means to provide (37).

Further, the position of the center of gravity of the rotation preventing stopper (31) is preferably lower than the center of gravity, and at least when it is fitted in the shaft hole (56) formed on the mounting plate (54), It must be located below the bottom surface of the mounting plate (54).

If the rotation preventing stopper (31) is provided with a connecting means (33) such as a chain, even if the rotation preventing stopper (31) comes off, it will not fall and be lost.

Further, the shaft holes (55) and (56) formed in the mounting plate (54) are located at positions outside the mounting plate (54) so as not to be blocked by the fixing leg portion (52). Yes, the shaft portion (17) of the stopper (11) is fitted in the shaft hole (55), and the leg portion (52) for fixing the stopper (11) in the shaft hole (56). Since the anti-rotation stopper (31) is inserted after pinching, the shaft holes (55) and (56) at these two locations are spaced at a fixed interval (L) so that the anti-rotation function is effectively exhibited. Shall be drilled.

[0018]

[Effect of the invention]

 According to the belt conveyor cover attachment according to the present invention described above, since the rotation prevention stopper (31) is made of metal such as stainless steel and has a heavy weight, the belt conveyor cover (50) may be blown by wind. The vibration of the belt conveyor itself eliminates the accidental removal of the rotation prevention stopper (31), and the stopper (11) may come off and the belt conveyor cover (50) may fall or harmful substances may spread. Disappears. For this reason, it is not necessary to perform patrol monitoring frequently, and maintenance costs such as safety confirmation can be kept low.

Further, since the rotation preventing stopper (31) itself is also provided with the connecting means (33), not only is there no risk of falling and falling, but also the material is made of stainless steel or the like having high corrosion resistance, and locking is performed. The protrusions (32) or steps (37) are used as the steps to make the structure simple with no moving parts, so that the handleability does not deteriorate over time and the belt conveyor cover (50 ) Can be fixed, the belt conveyor cover (50) can be easily replaced if necessary, and a belt conveyor cover mounting tool with low manufacturing cost can be provided.
