Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to an inclined shaft manned trolley with a double anti-skid structure. Background Art

[0002] Inclined shaft man-carrying trolley is a kind of transportation equipment with flexibility and high efficiency. It adopts the integrated design of man and vehicle, and can move, load and unload goods conveniently and quickly in narrow spaces such as factories and warehouses, greatly improving work efficiency. In inclined shaft excavation projects, an inclined shaft man-carrying trolley is often needed. However, when using it, attention should be paid to the anti-slip performance of the man-carrying trolley to prevent the man-carrying trolley from sliding and overturning when moving. Therefore, an inclined shaft man-carrying trolley with a double anti-slip structure is needed.

[0003] After searching, a Chinese patent with publication number CN102935851A discloses a mine car anti-derailment device. The structure is fixed at the first end of the rocker arm by a first driving device, which is used to axially position the inner rotating rod and drive the inner rotating rod to rotate. The structure can prevent the mine car from derailing due to lateral force in the swing track.

[0004] However, in actual use, the track of this structure must be installed on an "I"-shaped steel base with a considerable height, otherwise the track mounting pressure plate will restrict the operation of the anti-derailment plate, reducing practicality, and there is a phenomenon that the rear wheel will fall off the track due to a winch or wire rope failure.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As attached Figure 1-5The inclined shaft manned trolley with a double anti-skid structure shown in the figure comprises a trolley 1, a mounting frame 2 is arranged at the bottom of the trolley 1, a roller 3 is rotatably connected in the cavity of the mounting frame 2, a track 4 is arranged at the bottom of the roller 3, the trolley 1 and the track 4 are slidably connected through the roller 3, a groove is arranged on the lower surface of the trolley 1, a slider 5 is arranged inside the groove, a connecting rod 6 is arranged on the side surface of the mounting frame 2, a fastening block 7 is arranged at one end of the connecting rod 6, a first spring 8 is arranged on one side of the slider 5, the slider 5 is slidably connected to the groove, a cylindrical protrusion 9 is arranged on the other side of the slider 5, a connecting groove is arranged at one end of the connecting rod 6, the cylindrical protrusion 9 is connected to the connecting groove, and the cross section of the connecting rod 6 is arranged to be L-shaped. When using this device, The first spring 8 of the trolley 1 will keep the slider 5 in a stationary state. When the trolley 1 rolls over, the slider 5 immediately moves in the rollover direction and compresses the first spring 8. The cylindrical protrusion at one end of the slider 5 is inserted into the connecting groove of the connecting rod 6. After the slider 5 slides, the slider 5 drives the connecting rod 6 to rotate through the cylindrical protrusion at one end thereof. Since the connecting rod 6 and the mounting frame 2 are rotatably connected, the connecting rod 6 rotates around the mounting frame 2, so that the connecting rod 6 quickly contacts the track 4 through the fastening block 7 on its surface, preventing the rollover from continuing and improving safety. When the trolley 1 tilts toward the bottom of the well and causes the rear wheel to leave the track 4, the connecting rod 6 immediately buckles the track 4 through the fastening block 7, thereby preventing the trolley 1 from somersaulting forward.

[0021] As attached Figure 3 and Figure 5 As shown, a mounting groove is provided on the upper surface of the trolley 1, a linkage block 10 is provided inside the mounting groove, two upper slide plates 11 are provided on the lower surface of the linkage block 10, and the two upper slide plates 11 are both slidably connected to the trolley 1, a plurality of first tooth blocks 12 are provided on the surface of the upper slide plate 11, a transmission gear 13 is meshed and connected on one side of the first tooth block 12, a plurality of second tooth blocks 14 are provided on one side of the transmission gear 13, a lower slide plate 15 is provided on one side of the plurality of second tooth blocks 14, the two lower slide plates 15 are both slidably connected to the trolley 1, a second spring 16 is provided on one side of the lower slide plate 15, the second spring 16 is connected to the trolley 1, and a The friction pressure plate 17 is connected to the track 4. When people ride on the device, since the linkage block 10 is located at the center of the trolley 1, the people move closer to the center of the trolley 1, ensuring the stability of the center of gravity of the trolley 1, so that the linkage block 10 is stepped on and lowered, thereby driving the upper slide plate 11 to slide down. After the upper slide plate 11 slides down, it drives the transmission gear 13 to rotate through the first tooth block 12, so that the transmission gear 13 drives the lower slide plate 15 to rise through the first tooth block 12, and the lower slide plate 15 drives the friction pressure plate 17 at the lower end to slide up, thereby unlocking the trolley 1, enhancing the self-locking safety performance, which is beneficial to improving the practicality of the device during use.

[0022] The use process of the utility model is as follows: when using the device, the first spring 8 of the trolley 1 will keep the slider 5 in a stationary state. When the trolley 1 rolls over, the slider 5 immediately moves in the rollover direction and compresses the first spring 8. The cylindrical protrusion at one end of the slider 5 is inserted into the connecting groove of the connecting rod 6. After the slider 5 slides, the slider 5 drives the connecting rod 6 to rotate through the cylindrical protrusion at one end thereof. Since the connecting rod 6 and the mounting frame 2 are rotatably connected, the connecting rod 6 rotates around the mounting frame 2, so that the connecting rod 6 quickly contacts the track 4 through the fastening block 7 on its surface, preventing the rollover from continuing, thereby improving safety. When the trolley 1 tilts down the well and causes the rear wheel to leave the track 4, the connecting rod 6 immediately buckles the track 4 through the fastening block 7, thereby preventing the trolley 1 from somersaulting forward.

[0023] When the trolley 1 swings left and right during driving, the slider 5 moves in the rollover direction immediately, and at the same time pulls the connecting rod 6. The fastening block 7 on the connecting rod 6 quickly contacts the track 4 to prevent the rollover from continuing, and the slider 5 is kept stationary by the first spring 8. A slight swing in the normal state can also increase the friction and anti-skid performance by the fastening block 7, and the unbalance bolt is quickly reset after preventing the derailment phenomenon, thereby improving practicality. Since the linkage block 10 is located at the center of the trolley 1, people move closer to the center of the trolley 1, ensuring the stability of the center of gravity of the trolley 1, so that the linkage block 10 is stepped down, thereby driving the upper slide plate 11 to slide down. After the upper slide plate 11 slides down, it drives the transmission gear 13 to rotate through the first tooth block 12, so that the transmission gear 13 drives the lower slide plate 15 to rise through the first tooth block 12, and the lower slide plate 15 drives the friction pressure plate 17 at the lower end to slide up, thereby unlocking the trolley 1, enhancing the self-locking safety performance, which is beneficial to improving the practicality of the device during use and ensuring the stability of the center of gravity of the trolley 1.
