Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and particularly relates to an elevator blocking and anti-falling device. Background Art

[0002] At present, the circulation and conveying operation of I-shaped wheels mostly adopts the method of roller conveyor line combined with elevator, wherein the elevator includes a frame and a conveying frame, and is provided with a driving module for controlling the rotation drive of the roller on the conveying frame, a sensing module for confirming the position of the I-shaped wheel, and a lifting module for driving the conveying frame to rise and fall in the frame. Through the use of the elevator, the docking and conveying of two roller conveyor lines at different heights can be realized. In the circulation and conveying operation of the finished I-shaped wheel, when the roller conveyor line conveys the I-shaped wheel to the conveying frame in the elevator, the sensing module (photoelectric sensor) in the elevator senses the position of the I-shaped wheel, and controls the driving module to start and stop the rotation of the roller, so that the I-shaped wheel stops conveying after reaching the appropriate position of the conveying frame, and controls the driving module to continue to convey the I-shaped wheel to another roller conveyor line after stopping, and finally resets and reciprocates according to the above process. In summary, since the operation of the conveyor frame of the elevator depends on the drive module and the sensor module, if these electronic modules fail, and the elevator itself lacks protective measures and emergency functions, the finished I-shaped wheels being transported on the conveyor frame are at risk of rushing out of the elevator, causing economic losses or harm to personnel.

DETAILED DESCRIPTION

[0018] In order to better understand the present invention, Figures 1 to 4 The implementation modes of the present utility model will be explained in detail.

[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0020] See also Figures 1 to 4The utility model discloses a hoist blocking and anti-falling device, comprising a mounting base 1 and a right-angle baffle 2, the top of the right-angle baffle 2 is bent, a rotating rod 3 is arranged on the mounting base 1, and the midpoint of the rotating rod 3 is rotatably connected to the mounting base 1, so that the rotating rod 3 can rotate freely on the mounting base 1, and a blocking rod 4 and a trigger rod 5 are respectively arranged at both ends of the rotating rod 3, wherein the length of the trigger rod 5 is longer than the blocking rod 4, and a pulley 6 is arranged at the end of each of the blocking rod 4 and the trigger rod 5, and a limiting ring 7 is arranged on the mounting base 1 below the connection of the rotating rod 3, and the limiting ring 7 is used to limit the rotation angle of the rotating rod 3.

[0021] In the preferred technical solution of this embodiment, the blocking rod 4 is connected to the connecting end of the rotating rod 3 at an angle of 40° to 45°, and the trigger rod 5 is connected to the connecting end of the rotating rod 3 at an angle of 40° to 45°.

[0022] In the preferred technical solution of this embodiment, a bolt through hole is provided at the midpoint of the rotating rod 3, a first bolt 8 threadedly connected to the mounting base 1 is passed through the bolt through hole, and a shaft sleeve 9 is provided between the first bolt 8 and the bolt through hole.

[0023] In the preferred technical solution of this embodiment, both pulleys 6 are bearings, and the inner ring of the bearing is penetrated by a second bolt 10, one of the bearings is connected to the blocking rod 4 through the second bolt 10, and the other bearing is connected to the trigger rod 5 through the second bolt 10.

[0024] In the preferred technical solution of this embodiment, the limiting ring 7 is detachably connected to the mounting base 1 via a third bolt 11 .

[0025] The preferred technical solution in this embodiment is that in order to facilitate the disassembly of the blocking and anti-dropping device, a plurality of mounting through holes 12 are provided on the mounting base 1 and the right-angle baffle 2, and connecting bolts 13 are passed through the mounting through holes 12.

[0026] The usage and principle of the utility model: Figure 4 As shown in , the mounting base 1 is fixedly mounted on the conveying frame 14 (mounted on both sides of the inlet and outlet), and the right-angle baffle 2 is fixedly mounted on the lower frame 15 of the elevator, and the right-angle baffle 2 corresponds to the upper mounting base 1 up and down. Figure 1As shown in , since the trigger rod 5 is longer than the blocking rod 4, when the conveying frame 14 is lifted, the trigger rod 5 naturally falls down due to its longer and heavier length until it contacts the limiting ring 7 and is limited. At this time, the blocking rod 4 at the other end of the rotating rod 3 faces upward, forming a barrier to the conveying frame 14 to prevent the I-shaped wheel from rushing out. When the conveying frame 14 descends, the pulley 6 on the trigger rod 5 first contacts the top of the right-angle steel plate, so that the trigger rod 5 slides on the top of the right-angle steel plate through the pulley 6. During this period, the rotating rod 3 and its blocking rod 4 also rotate around the midpoint. After the conveying frame 14 descends to the bottom, the blocking rod 4 at the other end of the rotating rod 3 is no longer facing upward (as shown in FIG. Figure 2 As shown in the figure, the conveyor frame 14 cannot be blocked. At this time, the conveyor frame 14 is connected to the roller conveyor line. After the driving module of the elevator is running, the I-shaped wheel is transported to the connected roller conveyor line. During the lifting or lowering process of the conveyor frame 14 of the elevator, the blocking rod 4 is always in an upward state, which can block and prevent the I-shaped wheel from rushing out. After the conveyor frame 14 is lowered into place, the blocking rod 4 is no longer upward, contacting the I-shaped wheel, and the conveyor frame 14 can be normally transported to the outside.
