Description

Technical Field

[0001] The present invention relates to the technical field of monorail cranes, and particularly to a hoisting device for underground transportation. Background Art

[0002] A monorail crane is a system that uses a special I-beam suspended above a roadway as a track, connects suspension vehicles with various functions into a vehicle group, and is towed by a traction device to run along the track; its traction power can be provided by wire ropes, diesel engines, storage batteries or pneumatic devices; monorail cranes are usually used in mines and cable construction for the auxiliary transportation of equipment and materials.

[0003] A Chinese patent document with the authorization announcement number CN116969325B discloses a hoisting and transporting device for a mine monorail crane, belonging to the field of hoisting and transportation, including an I-beam rail. The upper end of the I-beam rail is fixedly connected with a suspension bracket. A driving chamber is arranged on the right side below the I-beam rail. A plurality of driven wheels are movably connected in the grooves at the front and rear ends of the I-beam rail. One end of the driven wheel on the right side away from the I-beam rail is rotatably connected with a first fixing seat, and the lower end of the first fixing seat is fixedly connected with the driving chamber. One end of the driven wheel on the left side away from the I-beam rail is movably connected with a second fixing seat, and a crane is arranged below the second fixing seat; an auxiliary braking mechanism is arranged between the driving chamber and the crane, and the auxiliary braking mechanism is used to drive the crane to move synchronously. It can achieve synchronous braking between each crane and the track while the driving chamber makes an emergency brake, reduce the inertia generated by the sudden stop of the crane, and ensure the safety during the transportation of the monorail crane.

[0004] In the above patent document, the rubber sleeve is expanded for braking during emergency braking. However, after the rubber sleeve wears, its braking effect will decrease. When lifting a heavy object and making an emergency brake, the rubber sleeve is also difficult to withstand a large impulse. Once the rubber sleeve is damaged, its braking effect is lost, and safety problems are likely to occur. At the same time, in the case of an emergency brake, the suspension bracket itself will move forward under the action of inertia. The braking effect of the above technical solution is low, and there are certain safety hazards. Summary of the Invention

[0005] The present invention provides a hoisting device for underground transportation, aiming to solve the problem of poor braking effect when the hoisting device for underground transportation in the related technology makes an emergency brake.

[0006] Hoisting device for underground transportation, including a hanging rail, a driving assembly, a braking component and a mounting frame. The braking component includes an elastic component and a brake disc. The hoisting device further includes: an adjustable elastic member installed between the hanging frame and the mounting frame, a suspension rod that elastically slides in the up and down direction of the hanging frame, a load platform connected to the suspension rod, a brake pad, and an elastic guiding member that guides the brake pad up and down; when the suspension rod slides in the left and right direction, the adjustable elastic member is compressed and the hanging frame is pushed to contact the elastic guiding member, thereby pushing the movable end of the elastic guiding member upward, so that the brake pad contacts the hanging rail and contacts the braking component, so that the braking end of the braking component moves away from the hanging rail;

[0007] An inclined block connected to the bottom of the elastic guiding member. After the elastic guiding member moves upward, the suspension rod contacts the inclined block and is pushed upward to prevent the goods from moving.

[0008] The above technical solution can avoid the problems caused by brake failure due to long-term and emergency braking. At the same time, it can prevent the goods from moving under the inertial impulse during emergency braking and can adapt to the transportation of goods of different weights.

[0009] Preferably, the braking component includes a hydraulic rod, a brake disc and an elastic component. The hydraulic rod is fixedly connected to the mounting frame, and the elastic component is connected between the brake disc and the hydraulic rod; it can avoid the brake disc from failing to brake for a long time.

[0010] Preferably, the elastic component includes a first sleeve and a second sleeve. A connecting rod is slidably connected between the first sleeve and the second sleeve. A first spring is installed between the first sleeve and the connecting rod, and a second spring is installed between the second sleeve and the connecting rod. A protrusion is installed on the connecting rod. The first sleeve is fixedly connected to the output end of the hydraulic rod, and the brake disc is fixedly connected to the second sleeve; it can reduce the frictional force that the brake disc can exert.

[0011] Preferably, the elastic guiding member includes a guiding rod and a third spring. The guiding rod is slidably arranged up and down on the mounting frame, and the third spring is installed between the brake pad and the mounting frame; it plays a guiding role in the movement of the brake pad.

[0012] Preferably, push blocks are installed on the hanging frame on both sides of the brake pad, and the brake pad is trapezoidal; it enables the brake pad to move upward.

[0013] Preferably, a wedge block that pushes the protrusion away from the hanging frame is also installed on the hanging frame; it pushes the elastic component to move.

[0014] Preferably, a fifth spring is connected between the suspension rod and the hanging frame; it enables the suspension rod to move up and down and reset.

[0015] Preferably, the adjustable elastic member includes a threaded sleeve, a screw rod, and a fourth spring. The threaded sleeve is fixedly arranged on the mounting frame. The screw rod is threadedly connected to the hanging frame and is slidably connected to the threaded sleeve. The fourth spring is connected between the threaded sleeve and the screw rod to adjust the elastic force between the hanging frame and the mounting frame.

[0016] Adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0017] 1. In case of emergency braking, the suspension rod pushes the hanging frame to move significantly left and right. The wedge block pushes the protrusion away from the hanging frame, thereby reducing the braking force on the brake disc. The pushing block pushes the brake pad upward to contact the hanging rail and generate friction to compensate for the braking force of the brake disc, avoiding the failure of the brake disc to brake.

[0018] 2. When performing emergency braking, the brake pad and the guide rod move upward and drive the inclined block to move upward. When the guide rod contacts the inclined block, the guide rod will move upward, and one end of the platform for placing materials on the guide rod will be lifted, avoiding the movement of the goods under the inertial impulse.

Detailed Embodiments

[0026] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] As Figures 1-6 shown, a hoisting device for underground transportation includes a suspension rail 1, a driving assembly 2, a braking component 3, and a mounting bracket 4. The driving assembly 2 is used to drive the mounting bracket 4 to move along the suspension rail 1, and the braking component 3 is used to stop the driving assembly 2 from moving. The driving assembly 2 and the braking component 3 are both mounted on the mounting bracket 4.

[0028] The driving assembly 2 includes two driving motors 21. A driving wheel 22 is installed at the output end of the driving motor 21. The two driving wheels 22 are located on the front and rear sides of the suspension rail 1 to drive the mounting bracket 4 to move. Traveling wheels 5 are also installed on the left and right sides of the mounting bracket 4. By rotating the driving motor 21, the driving wheel 22 is driven to rotate. The driving wheel 22 rotates and clamps the suspension rail 1 so that the traveling wheels 5 travel along the suspension rail 1.

[0029] The braking component 3 includes a hydraulic rod 31 provided on the mounting bracket 4. A brake disc 32 that can contact the suspension rail 1 is installed at the output end of the hydraulic rod 31. An elastic component 33 is installed between the hydraulic rod 31 and the brake disc 32. When braking, the brake disc 32 is driven by the hydraulic rod 31 to move into contact with the suspension rail 1 for braking. At this time, the elastic component 33 is compressed.

[0030] When the braking component 3 performs an emergency brake or a long-term brake, the braking component 3 may experience a brake failure. To avoid such a situation, a suspension bracket 6 is provided on the mounting bracket 4. The suspension bracket 6 is slidably arranged on the mounting bracket 4 in the left-right direction. A brake pad 7 is installed on the mounting bracket 4. When the suspension bracket 6 slides left and right, the brake pad 7 is pushed into contact with the suspension rail 1 to perform an auxiliary braking operation.

[0031] In a specific embodiment of the present invention, the elastic component 33 includes a first sleeve 331 and a second sleeve 332. A connecting rod 333 is slidably connected between the first sleeve 331 and the second sleeve 332. A first spring 334 is installed between the first sleeve 331 and the connecting rod 333. A second spring 335 is installed between the second sleeve 332 and the connecting rod 333. A protrusion 336 is installed on the connecting rod 333. The first sleeve 331 is fixedly connected to the output end of the hydraulic rod 31, and the brake disc 32 is fixedly connected to the second sleeve 332.

[0032] An elastic guiding member 8 is installed between the brake pad 7 and the mounting bracket 4. The elastic guiding member 8 includes a guiding rod 81 slidably arranged on the mounting bracket 4 in the up-down direction. The brake pad 7 is trapezoidal and installed at the end of the guiding rod 81. A third spring 82 is installed between the brake pad 7 and the mounting bracket 4. Pushing blocks 61 are installed on the hanging bracket 6 on both sides of the brake pad 7. A wedge-shaped block 62 away from the hanging bracket 6 is also installed on the hanging bracket 6 at the position of the pushing protrusion 336. When performing an emergency brake, the hanging bracket 6 moves in the left-right direction. At this time, the wedge-shaped block 62 moves the pushing protrusion 336 in a direction away from the suspension rail 1. At this time, the second spring 335 is stretched and the first spring 334 is compressed. At this time, the braking force of the brake disc 32 on the suspension rail 1 is reduced. At the same time, the pushing block 61 pushes the brake pad 7 upward to make the brake pad 7 contact with the suspension rail 1 to increase the braking force. That is to say, the braking force on the brake disc 32 is reduced to avoid excessive wear and overheating of the brake disc 32, which may cause brake failure. At the same time, the brake pad 7 contacts the suspension rail 1 to compensate for the braking force.

[0033] In a further embodiment of the present invention, a suspension rod 64 is slidably arranged on the hanging bracket 6 in the up-down direction. A fifth spring 63 is connected between the suspension rod 64 and the hanging bracket 6. An inclined block 83 is fixedly arranged at the downward extending end of the guiding rod 81. An adjustable elastic member 9 is installed between the hanging bracket 6 and the mounting bracket 4. When transporting goods, they are transported on the platform of the suspension rod 64. During normal transportation, when a small-scale brake occurs, the suspension rod 64 moves together with the hanging bracket 6, and the goods will not shake greatly at this time. When performing an emergency brake, the suspension rod 64 will push the hanging bracket 6 to slide in the left-right direction, and make the guiding rod 81 move upward and drive the inclined block 83 to move upward. When the suspension rod 64 contacts the inclined block 83, it will move upward by a certain distance. Platforms for placing materials are connected to the suspension rods 64 on both left and right sides. This platform can be the cab or the load-carrying frame of the underground hoisting device, etc. For the convenience of representation, the present invention simplifies it to a flat plate in the drawings. When performing an emergency brake, one end of the suspension rod 64 will be lifted upward by a certain distance. At this time, it can prevent the goods from moving under the inertial impulse. If goods are hoisted on the left and right suspension rods 64, it can reduce the shaking of the goods caused by inertia.

[0034] The adjustable elastic member 9 includes a threaded sleeve 91, a screw rod 92, and a fourth spring 93. The threaded sleeve 91 is fixedly arranged on the mounting bracket 4. The screw rod 92 is threadedly connected to the hanging bracket 6 and is slidably connected to the threaded sleeve 91. The fourth spring 93 is connected between the threaded sleeve 91 and the screw rod 92. By rotating the screw rod 92 to compress or extend the fourth spring 93, its elastic coefficient can be increased or decreased, so as to adapt to the transportation of goods of different weights.

[0035] Specific working principle:

[0036] When the present invention is in use, under normal braking conditions, the inertia generated by the materials on the platform of the suspension rod 64 is small. Under the conditions of large braking force and long-term braking, the suspension rod 64 pushes the hanging bracket 6 to move significantly left and right. The wedge-shaped block 62 pushes the protrusion 336 away from the hanging bracket 6, thereby reducing the braking force on the brake disc 32. The pushing block 61 moves the brake pad 7 upward to contact the suspension rail 1 and generate friction to compensate for the braking force of the brake disc 32, avoiding the failure of the brake disc 32. During emergency braking, the brake pad 7 and the guide rod 81 move upward and drive the inclined block 83 to move upward. When the suspension rod 64 contacts the inclined block 83, the suspension rod 64 will move upward, and one end of the platform for placing materials on the suspension rod 64 will be lifted, avoiding the downward movement of the goods due to the inertia impulse during emergency braking.

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
