[0034] Example

[0035] See also Figure 1-Figure 2 As shown, the purpose of this embodiment is to provide an intelligent safety brake manpower rail transport vehicle, including a frame 1 of a transport vehicle, a connecting sleeve 2 is fixedly installed at the bottom of the frame 1, a rotating shaft 21 is rotatably installed inside the connecting sleeve 2, and insulating nylon wheels 22 are installed at both ends of the rotating shaft 21 for driving the frame 1 to move on the track, a gear 23 is fixedly installed on the outer surface of the rotating shaft 21, and a fixed block 3 fixedly installed at the bottom of the frame 1 is installed outside the gear 23, a through groove is provided on the side of the fixed block 3 close to the gear 23, and a plug-in block 31 is slidably installed inside the through groove, and the front end of the plug-in block 31 is plugged into the gear teeth of the gear 23 for limiting the gear 23 and the rotating shaft 21, and a pulling component 32 is installed at the tail end of the plug-in block 31, and the pulling component 32 is used to pull the plug-in block 31;

[0036] By installing a rotating shaft 21 and an insulating nylon wheel 22 at the bottom of the frame 1, the transport vehicle can be moved on the track. A gear 23 is sleeved and installed on the outer surface of the rotating shaft 21, and a fixed block 3 is installed on the outer side of the gear 23, so that the plug-in block 31 can be extended and retracted in the through groove in the fixed block 3 with the help of a pulling component 32. When the pulling component 32 is not pulled, the plug-in block 31 is plugged into the inside of the gear 23 to limit the rotating shaft 21, thereby limiting the insulating nylon wheel 22. When the transport vehicle is not in use, the transport vehicle can be braked. When the transport vehicle is transported and moved, the pulling component 32 can be pulled to pull the plug-in block 31 away from the gear 23, so that the transport vehicle can be moved and transported.

[0037] A fixing rod 4 is installed on the bottom side of the frame 1, a chain 41 is installed on the outer surface of the fixing rod 4, and an iron shoe 42 is installed on the other end of the chain 41. The iron shoe 42 is arranged in a triangular shape and is used to be clamped between the insulating nylon wheel 22 and the track to perform parking brake on the insulating nylon wheel 22.

[0038] Four iron shoes 42 are provided, and the four iron shoes 42 are located at the four corners of the frame 1 and distributed in a rectangular array, and are used to limit the insulating nylon wheel 22 .

[0039] By installing two fixing rods 4 at the bottom of the frame 1, the chain 41 can be connected to the fixing rod 4 to connect the iron shoe 42. When the transport vehicle stops, the iron shoe 42 can be inserted between the insulating nylon wheel 22 and the track at the bottom of the transport vehicle to jam the insulating nylon wheel 22 to prevent the transport vehicle from slipping.

[0040] First, considering how the plug-in block 31 adjusts the position of the rotating shaft 21 and the gear 23, the following example is presented: Figure 3-Figure 6 , the specific structure of the pulling component 32 is disclosed. The pulling component 32 includes a connecting frame 301 fixedly installed on the back of the plug-in block 31, and a connecting plate 1 302 and a connecting plate 2 303 are respectively installed on both sides of the connecting frame 301. A tension spring 304 is installed on the side of the connecting plate 1 302 and the connecting plate 2 303 away from the connecting frame 301, and a rotating plate 305 is installed on the other end of the two tension springs 304. Two vertically distributed connecting columns 306 are fixedly installed inside the through groove, and the other ends of the two rotating plates 305 are rotatably installed on the outer surfaces of the two connecting columns 306.

[0041] There are two rotating shafts 21 and two gears 23, which are symmetrically distributed at the bottom of the frame 1 and are used to drive the two sets of insulating nylon wheels 22 to rotate. There are two pulling components 32 and two fixing blocks 3, which are arranged on the outside of the two gears 23 in a linear array and are used to limit the two rotating shafts 21 and the gears 23 respectively.

[0042] Furthermore, the plug-in block 31 is installed inside the through slot, one end of which is plugged into the inside of the gear 23, and the other end of the connecting frame 301 is fixedly installed. The plug-in block 31 can be extended and retracted by pulling the connecting frame 301. Considering how the plug-in block 31 can be automatically reset, a connecting plate 1 302 and a connecting plate 2 303 are installed on both sides of the connecting frame 301, so that the connecting plate 1 302 and the connecting plate 2 303 can be connected to the rotating plate 305 through the tension spring 304, and the rotating plate 305 is hinged to the through slot through the connecting column 306. The inside of the groove causes the connecting frame 301 to be pulled backwards, and the connecting plates 1 302 and 2 303 on both sides pull the tension spring 304 backwards, causing the rotating plate 305 to rotate outside the connecting column 306. At the same time, the plug-in block 31 also leaves the gear 23 and no longer engages with the gear 23, allowing the rotating shaft 21 and the insulating nylon wheel 22 to rotate normally. Loosening the connecting frame 301 and resetting the tension spring 304 can automatically reset the plug-in block 31, and engaging and limiting the gear 23 and the rotating shaft 21 again.

[0043] It should be noted that two of the pulling assembly 32, the fixing block 3 and the plug-in block 31 are provided, and the gears 23 on the two rotating rods 5 are clamped to achieve the effect of stopping the transport vehicle and braking the transport vehicle.

[0044] Secondly, considering how to pull the connecting frame 301, Figure 2 and Figure 4 A rotating rod 5 is rotatably mounted inside the connecting frame 301, and a connecting steel bar 1 51 is fixedly mounted on the outer surface of the rotating rod 5. The connecting steel bar 1 51 is pulled backward to drive the plug-in block 31 to move backward in the through slot. A connecting rod 6 fixedly mounted on the bottom of the frame 1 is arranged in the middle of the two pulling components 32, and a rotating plate 61 is rotatably mounted on the outer surface of the connecting rod 6. A connecting hole 1 and a connecting hole 2 are provided on one side of the top of the rotating plate 61, and a connecting hole 3 is provided on the other side of the top of the rotating plate 61. The end of the connecting steel bar 1 51 away from the connecting frame 301 is installed inside the connecting hole 1, and a connecting steel bar 2 52 is installed inside the connecting hole 2. The other end of the connecting steel bar 2 52 is connected to the connecting frame 301 of the other pulling component 32, and a connecting steel bar 3 53 is installed inside the connecting hole 3. A fixing sleeve 54 is installed on the other end of the connecting steel bar 3 53, and the fixing sleeve 54 is rotatably sleeved on the outer surface of the fixing rod 4.

[0045] A pulling rod 7 is fixedly mounted at the bottom of the frame 1 , and a mounting groove is provided inside the pulling rod 7 . The pulling rod 7 is convenient for personnel to pull the frame 1 .

[0046] Furthermore, by connecting a connecting steel bar 1 51 to the rotating rod 5 in the connecting frame 301, and installing a rotating plate 61 that can rotate on the outer surface of the connecting rod 6 in the middle of the two pulling components 32, one end of the connecting steel bar 1 51 is connected to the connecting frame 301, and the other end is connected to the connecting hole 1 opened at the top of the rotating plate 61, and a connecting steel bar 2 52 is also connected to the connecting frame 301 of the other pulling component 32, so that the other end of the connecting steel bar 2 52 is also connected to the connecting hole 2 opened at the top of the rotating plate 61, and a connecting steel bar 3 53 inserted into the connecting hole 3 is installed on the top of the other side of the rotating plate 61, and the connecting steel bar 3 53 is installed in the fixing sleeve 54, and the fixing sleeve 54 is rotatably installed on the outer surface of the fixing rod 4. When the transport vehicle is used, personnel can slide the handle by pulling it. It is dynamically plugged into the installation groove opened inside the pulling rod 7, and the connecting steel bar 1 51 in the connecting frame 301 is connected through a soft connecting piece, and the other end of the connecting piece is inserted into the inside of the installation groove and connected to the pulling handle. When the person pulls the pulling handle, the pulling handle slides upward inside the pulling rod 7, driving the connecting piece to pull the connecting frame 301, so that the connecting steel bar 1 51 drives the rotating plate 61 to rotate, pulls the connecting steel bar 2 52, and pulls the other connecting frame 301, so that the plug-in block 31 is pulled away from the gear 23, so that the transport vehicle can be moved and transported. When the transport vehicle stops, the person releases the pulling handle, and the connecting frame 301 is pulled back to its original position by the tension spring 304, so that the plug-in block 31 is re-engaged with the gear 23, achieving the effect of parking the transport vehicle.

[0047] It should be noted that a pulling handle with a sliding limit can be installed in the installation groove inside the pulling rod 7, and the connecting piece can use a bendable steel wire to connect the pulling handle with the connecting frame 301. When pulling the transport vehicle, the pulling handle can slide in the installation groove to connect the connecting piece with the connecting frame 301 and pull the plug-in block 31.

[0048] Finally, considering that the transport vehicle cannot brake too fast when moving, which may cause safety hazards, Figure 7 The outer surface of the rotating shaft 21 is sleeved with an electromagnetic brake component 8, a control box 81 is installed at the bottom of the frame 1, and a speed detection device 82 installed at the bottom of the frame 1 is provided on the outside of the insulating nylon wheel 22 for detecting the rotation speed of the insulating nylon wheel 22.

[0049] The electromagnetic brake component 8 is sleeved on the outer surface of the rotating shaft 21, and then the electromagnetic brake component 8 is connected to the speed detection device 82 through the control box 81. The speed detection device 82 is installed on the outside of the insulating nylon wheel 22. The rotation speed of the wheel can be detected to judge the speed of the transport vehicle. When it exceeds the set value, an audible and visual alarm is issued, and the electromagnetic brake component 8 automatically brakes. The braking state can be released only after manual resetting, thereby achieving the effect of overspeeding braking of the transport vehicle and avoiding safety accidents caused by excessive speed of the transport vehicle.

[0050] It should be noted that the connection between the electromagnetic brake component 8 and the internal structure of the speed detection device 82 is a prior art, and its working principle is common knowledge to those skilled in the art and will not be described in detail here.

[0051] In summary, the working principle of this solution is as follows:

[0052] When the transport vehicle is in use, the connecting frame 301 is pulled, and the connecting frame 301 drives the plug-in block 31 to leave the gear 23 on the rotating shaft 21, so that the rotating wheel can drive the insulating nylon wheel 22 to move on the track, and the items placed on the frame 1 are transported. When the transport vehicle stops, the connecting frame 301 is no longer pulled, and the tension spring 304 pulls the connecting frame 301 to reset, so that the plug-in block 31 is inserted into the gear 23, and the rotating shaft 21 is limited, so that the transport vehicle can be parked on the track to prevent the transport vehicle from sliding;

[0053] When the transport vehicle stops and is being loaded with items, a person may touch the pull rod 7 and pull the pull assembly 32, so that the plug-in block 31 no longer engages the gear 23, causing the transport vehicle to slide. By installing four iron shoes 42 at the bottom of the frame 1, the iron shoes 42 can be inserted between the insulating nylon wheel 22 and the track when the transport vehicle stops, so as to apply the parking brake to the transport vehicle and prevent the transport vehicle from slipping.

[0054] During the driving of the transport vehicle, the moving speed cannot be limited. A speed detection device 82 is installed on the outside of the insulating nylon wheel 22, and the electromagnetic brake component 8 is connected through the control box 81. When the speed of the transport vehicle exceeds the set value, the electromagnetic brake component 8 is energized, and the magnetic force generated by the electromagnetic brake component 8 is used to brake the rotating shaft 21 to avoid safety accidents caused by the excessive speed of the transport vehicle.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
