Description

Technical Field

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

[0002] A trolley, or platform vehicle, is generally used in tunnels, hydropower inclined shafts, and mining systems to provide an operating platform for constructors. Commonly used trolleys include tunnel lining formwork trolleys, mine excavation trolleys, and inclined shaft expansion trolleys. At present, during inclined shaft excavation, a winch is generally used to lift the support trolley, thereby driving the support trolley to move in the inclined shaft.

[0003] When the anti-derail device is in use, once the track wheel rolls over, the anti-hook emergency brake is relied upon to achieve contact alone, which generates a huge rollover force that causes the track and the anti-hook emergency brake to frequently achieve braking contact, which is easy to cause wear of the track and the anti-hook emergency brake. In this way, the anti-hook emergency brake and the track are greatly worn and easily damaged. At the same time, contact friction is achieved by relying solely on one side, and synchronous contact on both sides cannot be achieved. In this way, the stability is still poor, which is not only easy to cause wear but also has a poor anti-derail effect.

[0004] After searching, the Chinese utility model patent with publication number CN218750782U discloses an anti-derail device for inclined shaft transportation. By setting a double limit assembly, the second adjusting screw ring block and the first adjusting screw ring block are guided and moved along the inner wall of the limit concave plate, and the two adjacent linkage concave frames can directly realize extrusion, so that the linkage concave frame drives the support rod to move the first rolling wheel, and the two rubber rings realize rolling contact after contacting with the track, which can play a double-sided limit anti-derail operation, and the two rubber rings realize rolling contact after contacting with the track, which will not cause greater wear.

[0005] In actual use, the anti-derailment device for inclined shaft transportation operates in a long inclined shaft and is in ascending motion. At the same time, due to the different load-bearing capacity on the trolley and the different number of constructors, the trolley may shake or even tilt and derail during the construction process, thereby reducing the stability and practicality of the trolley. The trolley is usually provided with traction by a winch, and the winch is connected to the trolley with a wire rope. The trolley is controlled to move up and down along the track by the pulling force of the winch and the gravity of the trolley. When operating in a stopped state, there is no additional auxiliary mechanism to stabilize the trolley, which makes the trolley easy to shake during operation and affect the workers' operation.

When the trolley 1 tips over, the trolley 1 will drive the mounting block 5 to tilt through the two rollers 3, so that the two mounting blocks 5 drive the pillars 8 to rest against the inner groove of the track 4. The two pillars 8 on one side of the trolley 1 can provide support for the movement of the trolley 1, which can effectively prevent the trolley 1 from continuing to tilt. When the two mounting blocks 5 move, the two first springs 7 can push the two pillars 8 to move toward the tilted side, so that the two pillars 8 drive the protrusions 10 to squeeze the arc surface at the top of the auxiliary bracket 11, so that the two extrusion wheels 9 can drive the auxiliary wheels 12 to contact the groove of the track 4, thereby increasing the friction between the two auxiliary wheels 12 and the groove of the track 4, thereby maintaining the stability of the trolley 1.

[0039] As attached Figure 3 As shown, motors 13 are installed on both sides of the left and right sides of the trolley 1, and screw rods 14 are installed on the output ends of the two motors 13. Extrusion blocks 15 are installed on the outsides of the two screw rods 14.

[0041] The use process of the utility model is as follows: through the mutual cooperation between various structures, when the trolley 1 is tilted, the trolley 1 will drive the two mounting blocks 5 on one side to be lifted, so that the two mounting blocks 5 can drive the grinding block 21 to squeeze the top surface of the groove inside the track 4 upward, so that the support 8 can be inside the top track 4, which can effectively prevent the trolley 1 from tipping over. At the same time, the support 8 can be pushed out by the thrust of the two first springs 7, so that the two support pillars 8 can drive the two extrusion wheels 9 to slide in the groove inside the track 4, and at the same time, the convex blocks 10 at the bottom of the two support pillars 8 push the arc surface at the top of the extrusion auxiliary bracket 11, so that the two auxiliary brackets 11 can drive the auxiliary wheels 12 to move downward. The two auxiliary brackets 11 increase the friction with the groove of the track 4 through the auxiliary wheels 12, which can effectively assist the two pillars 8 to prevent the trolley 1 from continuing to tilt. When the trolley 1 needs to stop on the track 4, the left and right motors 13 are started, and the left and right motors 13 are used to drive the screw rod 14 to rotate, so that the two screw rods 14 drive the two extrusion blocks 15 to move downward, and the extrusion blocks 15 move downward to squeeze the cutouts on the opposite sides of the two lateral push plates 17, so that the two lateral push plates 17 move back to back and squeeze the second spring 18, so that the two lateral push plates 17 can drive the two rubber columns 20 to be squeezed between the roller 3 and the track 4 through the friction rod 19, thereby increasing the stability during parking.
