Description

  The present invention relates to a guide member for preventing a fall of a conveyed product provided on both sides of a belt conveying surface of a belt conveyor that continuously conveys various conveyed items such as earth and sand and powder materials.

  For example, as shown in Patent Documents 1 and 2, the belt conveyor is provided with a head pulley such as a motor pulley for driving at one end of a main body frame mainly composed of a steel pipe and the like, and a tail pulley at the other end rotatably. An endless belt is wound around the head pulley and the tail pulley so that the belt can run freely. By moving the belt at a predetermined speed, various transport objects such as earth and sand and powder material supplied to the belt transport surface can be obtained. It can be continuously transported.

  Further, in the above belt conveyor, in order to prevent the transported material such as earth and sand or powder material from overflowing and dropping from the side of the belt transport surface, as shown in FIG. 7, on both sides of the transport surface 105a of the belt 105. In some cases, a guide member 109 called a skirt or the like for preventing the fall of the conveyed product is provided. The guide member 109 includes a guide plate 110 having an appropriate height standing along the belt conveying surface 105a, and a leg portion 111 that supports the guide plate 110 on the main body frame 102 of the conveyor 101. 111 and the steel pipe 106 which comprises the main body frame 102 are fastened and fixed so that the outer periphery of the steel pipe 106 may be held using the U volt | bolt 120, a hose band, etc., for example. Further, a rubber plate 115 that closes the gap with the belt conveying surface 105 a is provided at the lower end portion of the guide plate 110, and is fixed by a presser fitting 116.

  By the way, on the side surface of the main body frame 102 of the belt conveyor 101, a large number of side plates 108 for connecting the upper and lower steel pipes 106 of the main body frame 102, joint fittings for frame connection, and the like are arranged at appropriate intervals. At the position where the side plate 108 or the like is disposed, the U-bolt 120 or the hose band that is fastened by holding the outer periphery of the steel pipe 106 of the main body frame 102 cannot be used because it interferes with the side plate 108. For example, several types of guide members 109 are prepared in which the position of the leg portion 111 is slightly shifted in the longitudinal direction of the conveyor with respect to the guide plate 110, and the position of the leg portion 111 does not overlap the position of the side plate 108 among them. Is selected and installed.

  However, since the arrangement of side plates and joint fittings arranged on the side of the frame of the belt conveyor differs depending on the type of conveyor and the length of the conveyor, etc., in order to be able to attach the guide members to various conveyors without hindrance. In addition, it is necessary to prepare very many kinds of guide members in which the position of the leg portion is shifted little by little, which not only leads to an increase in cost, but also causes an attachment error or erroneous delivery, and there is room for improvement.

  In view of the above points, the present invention reduces the types of guide members as much as possible by reducing the number of types of guide members as much as possible by allowing the legs of the guide members to be freely attached to the position of the side plate or the like disposed on the side surface of the conveyor body frame. It is an object of the present invention to provide a guide member for preventing the fall of a conveyed product of a belt conveyor that can achieve the above.

  In order to solve the above-mentioned problem, the guide member for preventing the fall of the conveyed product of the belt conveyor according to the present invention is a guide member for preventing the fall of the conveyed product provided on both sides of the belt conveying surface of the belt conveyor, A steel plate constituting a main body frame at a lower end portion of the leg portion, the guide plate having a predetermined height standing along the belt conveying surface and a leg portion supporting the guide plate on the main body frame of the conveyor. A concave bolt that is placed and locked on the upper end surface of the steel pipe is formed, and a fixing bolt is provided so that the tip of the bolt faces the lower side of the steel pipe, and at the lower side of the steel pipe when the fixing bolt is tightened. The abutting bolt tip portion presses the steel pipe upward, thereby sandwiching the steel pipe with the concave portion and fixing the leg portion.

  According to the guide member for preventing the fall of the conveyed product of the belt conveyor according to the present invention, the guide member for preventing the fall of the conveyed product provided on both sides of the belt conveying surface of the belt conveyor, the guide member being arranged along the belt conveying surface. A guide plate having a predetermined height and a leg portion that supports the guide plate on the main body frame of the conveyor. The lower end portion of the leg portion is placed on the upper end surface of the steel pipe constituting the main body frame. The fixing bolt is provided so that the bolt tip faces the lower side of the steel pipe, and the bolt tip contacting the lower side of the steel pipe is tightened when the fixing bolt is tightened. By pressing the steel pipe upwards, the steel pipe is sandwiched between the recesses and the legs are fixed, so that the legs of the guide member can be freely attached to the side plate position of the main body frame. Thereby reduce the types of the guide member along with the cost can be reduced What can be expected the reduction of such mounting errors or misdirected.

It is a figure equivalent to FIG. 4 which shows another Example. It is a figure equivalent to FIG. 4 which shows another Example. It is a figure equivalent to FIG. 2 which shows a prior art example.

  As shown in FIG. 2, the guide member 9 for preventing the fall of the conveyed product of the belt conveyor according to the present invention includes a guide plate 10 erected along the conveying surface 5a of the belt 5 of the conveyor 1, and the guide. A leg portion 11 for supporting the plate 10 on the main body frame 2 of the conveyor 1 is formed. At the lower end portion of the leg portion 11, a recessed portion 12 that can be placed and locked on the upper end surface of the steel pipe 6 of the main body frame 2 is formed. On the other hand, the bolt 13 for fixing is provided so that the bolt front-end | tip part 13a may face the lower part side of the said steel pipe 6 from the side. As shown in FIG. 4, when the fixing bolt 13 is tightened to the steel pipe 6 side (in the direction of arrow A in FIG. 4), the bolt tip 13 a that is in contact with the lower side of the steel pipe 6 By pressing upward (in the direction of arrow B in FIG. 4), the steel pipe 6 is sandwiched between the recesses 12 and the legs 11 are fixed.

  With this configuration, when the leg portion 11 of the guide member 9 is fixed to the steel pipe 6 of the main body frame 2 of the conveyor 1, the outer circumference of the steel pipe 6 is not held like a U bolt or a hose band. It can be freely attached to the position of the side plate 8 or the like disposed on the main body frame 2, thereby preparing a guide member having a different leg position for each type of conveyor having a different position of the side plate or the like as in the prior art. This eliminates the need to reduce the number of types of guide members and reduce costs, and it can also be expected to reduce mounting errors and misfeeds caused by the variety of types.

  An embodiment of the present invention will be described below with reference to FIGS.

  In the figure, reference numeral 1 designates a head pulley 3 such as a motor pulley for driving at one end of a main body frame 2 mainly composed of a steel pipe 6 and the like, and a tail pulley 4 at the other end rotatably supported. A belt conveyor in which an endless belt 5 is movably wound between the belt and the tail pulley 4, and the belt 5 is caused to travel at a predetermined speed so that earth, sand, powder material, or the like supplied to the belt conveying surface 5a is obtained. It is possible to transport various types of transported items continuously.

  In this embodiment, the main body frame 2 has an intermediate frame 2b of an appropriate length interposed between a head frame 2a having a head pulley 3 and a tail frame 2c having a tail pulley 4. It is constructed by connecting with the joint bracket 7 and adopts a unit type that can easily adjust the machine length of the conveyor 1 according to the application by adjusting the length of the intermediate frame 2b. . In addition, on the side surfaces of the frames 2a, 2b, and 2c, a large number of side plates 8 that connect the upper and lower steel pipes 6 constituting the frame are arranged at appropriate intervals.

  9 is a guide member for preventing the fall of the transported material from the side of the belt transport surface 5a and prevents the transported material from falling, and is provided along the both sides of the belt transport surface 5a. A substantially L-shaped guide plate 10 formed to have an appropriate height according to the type and properties of the plate, and two plate bodies 11a and 11b that support the guide plate 10 on the main body frame 2 have a substantially T-shaped cross section. A substantially arcuate recess 12 which can be placed on and locked to the upper end surface of the steel pipe 6 of the main body frame 2 at the lower end of the plate 11b of the leg 11. On the other hand, a fixing bolt 13 is provided at the lower end of the plate 11a so that the bolt tip 13a faces the lower side of the steel pipe 6 from the side.

  14 is a hooking piece formed so as to hang down to the tip end side of the recess 12 formed at the lower end of the plate body 11b. When the steel pipe 6 is pressed by the fixing bolt 13, the force is not released. It is intended to be received firmly. A rubber plate 15 closes the gap between the lower end portion of the guide plate 10 and the belt conveying surface 5a. The upper end portion of the rubber plate 15 is pressed by a pressing metal 16 provided on the back side of the guide plate 10. To fix.

  When the guide member 9 for preventing the fall of the conveyed product is fixed and supported on the main body frame 2 of the conveyor 1, the concave portion 12 formed at the lower end of the plate 11 b of the leg portion 11 of the guide member 9 is formed on the main body frame 2. After mounting and locking on the upper end surface of the steel pipe 6, when the fixing bolt 13 is tightened to the steel pipe 6 side (in the direction of arrow A in FIG. 4), the bolt tip portion 13 a contacts the lower end portion of the steel pipe 6. Then, the steel pipe 6 is pressed upward (in the direction of arrow B in FIG. 4), whereby the steel pipe 6 is sandwiched between the concave portion 12 and the retaining piece 14 to firmly fix the leg portion 11.

  Thus, when fixing the leg part 11 of the guide member 9 to the steel pipe 6 of the main body frame 2 of the conveyor 1, the main body frame 2 is not held around the outer circumference of the steel pipe 6 like a U bolt or a hose band. The side plate 8 and the joint bracket 7 can be freely attached to the position, so that a relatively small number of guide members can sufficiently cope with various conveyors having different arrangements of the side plate 8 and the joint bracket 7 and the like. In addition to being able to achieve downsizing, it can also be expected to reduce mounting mistakes and misdelivery.

  FIG. 5 is a diagram for explaining another embodiment of the present invention, which corresponds to FIG. 4 of the first embodiment. In this second embodiment, the lower end of the plate 11b of the leg portion 11 of the guide member 9 is shown. The concave portion 12 formed in the portion is not substantially arc-shaped as in the first embodiment, but is substantially L-shaped.

  And when fixing this guide member 9 to the main body frame 2 of the conveyor 1, the recessed part 12 of the leg part 11 lower end part is used for the upper end surface of the steel pipe 6 of the main body frame 2 similarly to the case where the guide member of Example 1 is fixed. When the fixing bolt 13 is tightened to the steel pipe 6 side (in the direction of arrow A in FIG. 5), the bolt tip 13a moves the steel pipe 6 upward (in the direction of arrow B in FIG. 4). ), Whereby the steel pipe 6 is sandwiched between the concave portion 12 and the retaining piece 14 to firmly fix the leg portion 11. At this time, the steel pipe 6 is fixedly supported at three points, that is, a bolt front end portion 13a, a horizontal edge portion that forms a substantially L-shaped concave portion 12, and a vertical edge portion of the latching piece 14, and is thus more robust. It is suitable that it can be fixed to.

  FIG. 6 is a view for explaining still another embodiment of the present invention and corresponds to FIG. 4 of the first embodiment. In this third embodiment, the plate body 11b of the leg portion 11 of the guide member 9 is shown. While the concave portion 12 formed at the lower end portion has a substantially arc shape similar to that of the first embodiment, the distal end side of the concave portion 12 does not have a portion corresponding to the latching piece of the first embodiment. The guide member 9 of the third embodiment can be suitably employed when there is a possibility that some member or the like exists on the inner side (belt side) of the steel pipe 6 of the conveyor and the latching piece may interfere with it.

  And when fixing this guide member 9 to the main body frame 2 of the conveyor 1, the recessed part 12 of the leg part 11 lower end part of the steel pipe 6 of the main body frame 2 is fixed like the case where the guide member of Example 1, 2 is fixed. When the fixing bolt 13 is tightened to the steel pipe 6 side (in the direction of arrow A in FIG. 5) after being placed and locked on the upper end surface, the bolt tip 13a moves the steel pipe 6 upward (indicated by the arrow in FIG. 4). B direction), the steel pipe 6 is pinched by the said recessed part 12, and the leg part 11 is fixed by this. At this time, since there is no latching piece as in the first embodiment at the distal end side of the recess 12, the supporting force for receiving the force that presses the steel pipe 6 with the bolt distal end portion 13a is slightly weakened, but the leg portion 11 is attached to the steel pipe 6 There is no particular effect on the amount of fixed support.
