Description

Technical Field

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

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

[0003] The Chinese patent document with the authorization announcement number CN116969325B discloses a mining monorail crane hoisting and transportation device, which belongs to the field of hoisting and transportation, including an I-beam rail, the upper end of which is fixedly connected to a hanger, a drive chamber is provided on the right side below the I-beam rail, and multiple sets of driven wheels are movably connected in the grooves at the front and rear ends of the I-beam rail, the right side of the driven wheel away from the I-beam rail is rotatably connected to a first fixed seat, and the lower end of the first fixed seat is fixedly connected to the driving chamber, the left side of the driven wheel away from the I-beam rail is movably connected to a second fixed seat, and a crane is provided below the second fixed seat; an auxiliary brake mechanism is provided between the driving chamber and the crane, and the auxiliary brake 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 is in emergency braking, reducing the inertia of the crane caused by the immediate stop, and ensuring the safety of the monorail crane in transportation.

[0004] In the above patent document, the rubber sleeve is expanded to brake during emergency braking, but its braking effect will be reduced after the rubber sleeve is worn. When lifting heavy objects and emergency braking is performed, the rubber sleeve is also difficult to withstand a large impulse. Once the rubber sleeve is damaged, its braking effect is lost, which is prone to safety problems. At the same time, in the case of emergency braking, the hanger 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 that the hoisting device for underground transportation in the related art has a poor braking effect when performing emergency braking.

[0006] A hoisting device for underground transportation, comprising a hanging rail, a driving assembly, a brake component and a mounting frame, wherein the brake component comprises an elastic assembly and a brake disc, and the hoisting device further comprises: an adjustable elastic member installed between the hanger and the mounting frame, a hanger rod elastically sliding along the hanger in the up and down directions, a loading platform connected to the hanger rod, a brake pad and an elastic guide member guiding the brake pad up and down; when the hanger rod slides in the left and right directions, the adjustable elastic member is compressed and the hanger is pushed to contact the elastic guide member, and then the movable end of the elastic guide member is pushed upward, so that the brake pad is in contact with the hanging rail and the brake component, so that the brake end of the brake component is away from the hanging rail; The tilting block is connected to the bottom of the elastic guide member. After the elastic guide member moves upward, the suspension rod contacts the tilting block, thereby pushing the suspension rod to rise to prevent the cargo from moving.

[0007] The above technical solution can avoid the problem of brake failure caused by long-term and sudden braking, and can also prevent the goods from moving under the inertial impulse during sudden braking, and can adapt to the transportation of goods of different weights.

[0008] Preferably, the brake component includes a hydraulic rod, a brake disc, and an elastic component, wherein the hydraulic rod is fixedly connected to the mounting frame, and the elastic component is connected between the brake disc and the hydraulic rod; this can prevent the brake disc from failing for a long time.

[0009] 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, 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; so that the friction force that the brake disc can apply is reduced.

[0010] Preferably, the elastic guide member includes a guide rod and a third spring. The guide rod is slidably arranged on the mounting frame up and down, 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.

[0011] Preferably, the hanger is provided with push blocks located on both sides of the brake pad, and the brake pad is in a trapezoidal shape, so that the brake pad can move upward.

[0012] Preferably, the hanger is also provided with a wedge-shaped block for pushing the protrusion away from the hanger, thereby pushing the elastic component to move.

[0013] Preferably, a fifth spring is connected between the suspension rod and the hanger bracket, so that the suspension rod can move up and down and reset.

[0014] 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 hanger and is slidably connected to the threaded sleeve. The fourth spring is connected between the threaded sleeve and the screw rod; the elastic force between the hanger and the mounting frame is adjusted.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. In case of emergency braking, the suspension rod pushes the hanger to move left and right significantly, and the wedge block pushes the protrusion away from the hanger, thereby reducing the braking force on the brake disc. The push block pushes the brake pad upward to contact the hanging rail and generate friction to compensate for the braking force of the brake disc, thus avoiding brake failure; 2. When emergency braking is performed, the brake pad and guide rod move upward and drive the tilting block to move upward. When the guide rod contacts the tilting block, the guide rod will move upward, and one end of the platform on the guide rod where the material is placed will be lifted to prevent the goods from moving under the inertial impulse.

DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figure 1-Figure 6 As shown, the hoisting device for underground transportation includes a hanging rail 1, a driving component 2, a brake component 3 and a mounting frame 4. The driving component 2 is used to drive the mounting frame 4 to move along the hanging rail 1, and the brake component 3 is used to stop the movement of the driving component 2. The driving component 2 and the brake component 3 are both installed on the mounting frame 4.

[0025] The driving assembly 2 includes two driving motors 21, and 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 hanging rail 1 to drive the mounting frame 4 to move. The mounting frame 4 is also equipped with walking wheels 5 on the left and right sides. The driving wheel 22 is driven to rotate by the rotation of the driving motor 21, and the driving wheel 22 rotates and clamps the hanging rail 1 so that the walking wheel 5 can move along the hanging rail 1.

[0026] The brake component 3 includes a hydraulic rod 31 arranged on the mounting frame 4. A brake disc 32 that can contact the hanging 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 moved and contacted with the hanging rail 1 by the hydraulic rod 31 to perform braking. At this time, the elastic component 33 is compressed.

[0027] When the brake component 3 is braked suddenly or for a long time, the brake component 3 may fail. To avoid such a situation, a hanger 6 is arranged on the mounting frame 4. The hanger 6 is slidably arranged on the mounting frame 4 along the left and right directions. A brake pad 7 is installed on the mounting frame 4. When the hanger 6 slides left and right, it pushes the brake pad 7 to contact the hanging rail 1 to perform an auxiliary braking operation.

[0028] 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.

[0029] An elastic guide member 8 is installed between the brake pad 7 and the mounting frame 4, and the elastic guide member 8 includes a guide rod 81 slidably arranged on the mounting frame 4 in the up and down directions. The brake pad 7 is trapezoidal and is installed at the end of the guide rod 81. A third spring 82 is installed between the brake pad 7 and the mounting frame 4. The hanger 6 is provided with pushing blocks 61 located on both sides of the brake pad 7. The hanger 6 is also provided with a wedge block 62 for pushing the protrusion 336 away from the hanger 6; when emergency braking is performed, the hanger 6 moves along the left and right directions. At this time, the wedge block 62 will push the protrusion 336 to move in the direction away from the hanging 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 hanging rail 1 is reduced, and at the same time, the pushing block 61 will push the brake pad 7 to move upward and make the brake pad 7 contact with the hanging 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 and cause brake failure. At the same time, the brake pad 7 contacts with the hanging rail 1 to compensate for the braking force.

[0030] In a further embodiment of the present invention, a suspension rod 64 is provided for sliding in the up-and-down directions of the hanger 6, a fifth spring 63 is connected between the suspension rod 64 and the hanger 6, a tilting block 83 is fixedly provided at the downwardly extending end of the guide rod 81, and an adjustable elastic member 9 is installed between the hanger 6 and the mounting frame 4; when transporting goods, the goods are placed on the platform of the suspension rod 64 for transportation. During normal transportation, when a small brake occurs, the suspension rod 64 moves with the hanger 6, and the goods will not produce a large shake at this time. When an emergency brake is applied, the suspension rod 64 will push the hanger 6 slides in the left and right directions, and makes the guide rod 81 move upward and drives the tilting block 83 to move upward. When the suspension rod 64 contacts the tilting block 83, it will move upward for a distance. The suspension rods 64 on the left and right sides are connected to a platform for placing materials. The platform can be a cab, a loading frame, etc. of the underground lifting device. For the convenience of representation, the present invention is simplified to a flat plate in the accompanying drawings. When emergency braking is performed, one end of the suspension rod 64 will be lifted upward for a distance. At this time, the goods can be prevented from moving under the inertial impulse. If goods are hoisted on the left and right suspension rods 64, the shaking of the goods due to inertia can be reduced.

[0031] 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 frame 4, the screw rod 92 is threadedly connected to the hanger 6 and is slidably connected to the threaded sleeve 91, and the fourth spring 93 is connected between the threaded sleeve 91 and the screw rod 92. The fourth spring 93 is compressed by rotating the screw rod 92 or the fourth spring 93 is stretched to increase or decrease its elastic coefficient, thereby being able to adapt to the transportation of goods of different weights.

[0032] Specific working principle: When the present invention is in use, under normal braking conditions, the inertia generated by the materials on the platform of the boom 64 is relatively small. Under conditions of large braking force or long braking time, the boom 64 pushes the hanger 6 to move left and right significantly, and the wedge block 62 pushes the protrusion 336 away from the hanger 6, thereby reducing the braking force on the brake disc 32. The push block 61 will push the brake pad 7 to move upward to contact the hanging rail 1 and generate friction to compensate for the braking force of the brake disc 32, thereby avoiding failure of the brake disc 32. When emergency braking is performed, the brake pad 7 and the guide rod 81 move upward and drive the tilting block 83 to move upward. When the boom 64 contacts the tilting block 83, the boom 64 will move upward, and one end of the platform on which the materials are placed on the boom 64 will be lifted, thereby avoiding the movement of the goods due to inertial impulse under emergency braking conditions.

[0033] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
