[0002] After the overhead crane has finished loading, the train carriage needs to be flattened. The mechanical flattening device will cause materials to spill, and because the carriages are of different heights, the mechanical flattening device cannot be used. At this time, manual flattening is required. The height of the train sidecar is more than two meters above the ground, which is considered high-altitude operation, and it is impossible to fix and install reliable safety belt bolt hanging points above the train. Operators need to frequently get on and off the train, cross the sidecar and remove the safety belts, and height-falling accidents are prone to occur during the operation. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the implementation cases of the utility model clearer, the technical solution in the implementation cases of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation cases. Obviously, the implementation cases described are only a small part of the implementation cases of the utility model, rather than all the implementation cases. Based on the implementation cases in the utility model, all other implementation cases obtained by ordinary technicians in this field without making creative work are within the protection scope of the utility model.
[0017] A safety protection device for providing a restricted area for personnel on a train material flat car, comprising a fixed pulley 1, a transverse support 3, a safety belt bolt pulley 4, a winch 6, a safety rope 7 and a slide rail 8, wherein the fixed pulley 1 is fixed on a wall steel plate, and the winch 6 is fixed below the wall; one end of the transverse support 3 is welded to a heavy shaft, and the fixed end of the heavy shaft is welded to the wall steel plate, and the other end of the transverse support 3 is connected to a steel wire rope, which passes upward through the fixed pulley 1 and is then connected downward to the winch 6; the slide rail 8 is arranged along the radial direction of the body of a train 5, and is welded below one end of the transverse support 3 away from the wall steel plate, the safety belt bolt pulley 4 is slidably arranged on the slide rail 8, and the safety rope 7 is connected to the safety belt bolt pulley 4.
[0018] The safety belt bolt hanging pulley 4 comprises a bearing 41 , a shaft 42 , a shaft sleeve 43 and a safety belt bolt hanging point 44 . Both ends of the shaft 42 pass through the bearings 41 . The shaft sleeve 43 is arranged between the two bearings 41 . The safety belt bolt hanging point 44 is fixedly arranged between the two shaft sleeves 43 .
[0019] It also includes a limiting device 2, which is arranged on the wire rope to adjust the rising or falling position of the cross support 3.
[0020] The length of the transverse support 3 is the length from the wall to the center of the vehicle body, and the number of the transverse supports 3 is more than one; a lifting ring is welded on the upper end of the transverse support 3, and a steel wire rope is connected to the transverse support 3 through the lifting ring.
[0021] The length of the slide rail 8 matches the length of the factory building, and plugs are welded at both ends.
[0022] In actual application, holes are punched at the four corners of a steel plate of 200*200*5MM in size, and the plate is installed to a suitable height of the wall with expansion bolts (the specific height should be 2.5M higher than the highest side of the vehicle), the fixed end of the heavy-duty shaft is welded on the steel plate, and a cross support 3 is made of a steel pipe (the length of the cross support can be from the wall to the center of the vehicle body), the heavy-duty shaft is welded to one end of the cross support, and a lifting ring is welded at the other end of the cross support to allow the wire rope to pass through; a winch 6 is fixedly installed below the wall, and a fixed pulley 1 is installed on the wall above the winch close to the roof. The wire rope coming out of the winch drum passes through the fixed pulley and is connected downward to the lifting ring on the cross support. When the winch drum is tightened, the wire rope pulls one end of the cross support upward, and the other end rotates around the heavy-duty shaft until one end of the cross support is close to the wall (it cannot be pulled vertically to the ground, and is adjusted by a limit device). At this time, the cross support is retracted, which does not affect the normal loading and unloading operation of the overhead crane; when the winch is relaxed, the steel pipe drops to a suitable position by gravity and stops, and the wire rope drum is locked.
[0023] Use a 6MM gap cut on one side of a 50*50MM square steel as the slide rail 8. Multiple horizontal supports can be installed according to the length of the factory building. The upper side of the slide rail 8 is welded below the end of all horizontal support rings. If the length is not enough, multiple slide rails can be welded end to end. The length of the slide rail should be slightly shorter than the length of the factory building. Two sections of welding plugs prevent slipping. The winch can be installed on both sides and in the middle of the factory building. It can be operated simultaneously through the linkage power supply (the power supply should be controlled by jog). Adjusting the limit device 2 can make the horizontal support rise and fall to the appropriate position without overwinding or placing the horizontal support too low. The horizontal support that is not connected to the winch can be fixed and bolted with a wire rope of appropriate length near the fixed pulley or bolting point on the roof. After the winch is placed in the appropriate position, all wire ropes should be straightened to achieve the purpose of reliable load-bearing.
[0024] The main components of the safety belt bolt pulley 4 are bearing 41, shaft 42, shaft sleeve 43 and safety belt bolt hanging point 44. The specification of bearing 41 is 6004-2RS, the length of shaft 42 is 40MM and the diameter is 20MM, and the safety belt bolt hanging point 44 is a lifting ring made of 5MM steel plate. The two ends of shaft 42 pass through bearing 41, and the shaft sleeve 43 passes through and fixes the safety belt bolt hanging point 44, and a safety rope 7 is hung. The other end of the safety rope is connected to the safety ring of the operator's torso safety belt with a D-shaped safety bayonet. The length of the safety rope should allow the operator to reach the side of the lowest car on both sides of the car, and cannot step out of the car side, forming a restriction on the working area, so as to prevent the operator from falling from a height.
