Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically a double-layer mining elevator car. Background Technology

[0002] With the progress of the times, elevators are being used more and more widely. The demand for hoisting equipment in my country's coal industry is also increasing. However, traditional single-shaft single-car elevators can no longer meet the requirements. To improve the carrying efficiency, the only way is to increase the number of elevator shafts. Although this solves the problem of carrying efficiency, the large number of elevator shafts occupies a large amount of underground area, which is not cost-effective.

[0003] Currently, most mines solve this problem by using large-tonnage cages and skips. While these can carry the corresponding weight of goods, they are inconvenient and energy-inefficient to operate. Firstly, these hoisting devices lack sufficient height for overall assembly and transportation. Secondly, they are inconvenient for simultaneously transporting people and equipment while ensuring their safety.

[0004] Chinese invention patent CN105668383A discloses a double-layer, high-tonnage elevator car with adjustable car height and an adjustment method. The elevator car includes a car body with a partition inside, dividing the car body into upper and lower floors. An adjustment system is provided above the partition, which can move the partition body up and down. The adjustment system includes an adjustment motor, guide wheels, a movable pulley block, a fixed pulley block, a roller, an adjustment wire rope, and a traction wire rope. The roller is mounted on the output shaft of the adjustment motor. The adjustment wire rope is wound around the movable and fixed pulley blocks. One end of the adjustment wire rope passes over the guide wheel and is connected to the roller. The other end of the adjustment wire rope is fixed to the top of the car body. One end of the traction wire rope is connected to the movable pulley block, and the other end of the traction wire rope is connected to the partition.

[0005] The gap between the partition and the inner wall of this type of elevator car is relatively narrow, making it difficult to clean the slag located between the partition and the inner wall of the car. Utility Model Content

[0006] The purpose of this utility model is to provide a double-layer mining elevator car to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A double-decker mining elevator car includes:

[0009] The car has a partition that divides it into an upper and lower level. The distance between the partition and the side wall of the car is greater than 1 cm. The partition can be moved up and down to adjust the space between the upper and lower levels of the car. The greater than 1 cm distance between the partition and the side wall of the car facilitates the removal of slag between the partition and the side wall using tools, such as a stick.

[0010] A lifting assembly is located above the partition and is used to move the partition up and down.

[0011] At least five sets of roller assemblies are provided. The roller assemblies are installed on the bottom surface of the partition and correspond to the side walls of the car. At least two sets of roller assemblies correspond to the side walls of the car with doors. At least one set of roller assemblies corresponds to the other three side walls of the car. Each roller assembly includes a mounting plate and four rollers. The four rollers are rotatably mounted on the four corners of the mounting plate via a rotating shaft. The mounting plate is fixed to the bottom surface of the partition. The rollers roll in contact with their corresponding side walls. By setting four rollers on the mounting plate and distributing the four rollers in a rectangular pattern, the stability of the partition moving up and down in the car is improved.

[0012] This invention uses a roller assembly for contact between the partition and the car, so that the partition does not directly contact the inner wall of the car. Therefore, the distance between the inner wall of the car and the partition can be increased, making it easier to use tools to clean the slag stuck between the inner wall of the car and the partition.

[0013] This utility model sets up a roller assembly, in which the rollers of the roller assembly contact the inner wall of the car. Roller assemblies are set near the four sides of the bottom of the partition to correspond to the four inner side walls of the car. Each set of roller assemblies has four rollers arranged in a rectangular shape, which can restrict the movement direction of the partition and guide the partition to move up and down in the car.

[0014] This invention reduces friction between the partition and the inner wall of the car by using a roller assembly, thereby reducing wear between them.

[0015] Specifically, the lifting assembly includes a winch installed on the top of the car. The top of the car has a through hole, and the wire rope of the winch passes through the through hole and connects to the partition to drive the partition to move up and down. The winch is existing technology. When the winch rewinds, the wire rope of the winch can pull the partition up. When the winch unwinds, the partition will descend under the action of gravity.

[0016] Furthermore, a rack is provided on the inner side wall of the car in the vertical direction, a locking chamber is provided at the bottom of the partition, and a self-locking component is provided in the locking chamber;

[0017] The self-locking assembly includes a gear, a ratchet, a pawl that engages with the ratchet, a mounting shaft, a tension spring, and an electromagnet. The mounting shaft is rotatably mounted inside the locking chamber. The gear and the ratchet are coaxially fixed on the mounting shaft. The gear meshes with the rack. The pawl has two ends: a first end and a second end. The second end is rotatably connected to the locking chamber. When the car descends, the ratchet rotates in a first direction. The two ends of the tension spring are respectively connected to the first end and the locking chamber to pull the pawl, causing the first end to approach the ratchet and engage with it. When the ratchet engages with the pawl, the pawl prevents the ratchet from rotating in the first direction. The electromagnet is mounted on the inner wall of the locking chamber to attract the first end, causing it to move away from the ratchet. Through the rack, gear, ratchet, pawl, tension spring, and electromagnet, the partition can be locked to prevent it from descending.

[0018] Furthermore, the edge of the partition is provided with a brush, which can fill the gap between the car and the partition to prevent slag from falling into the gap between the partition and the car.

[0019] Furthermore, the inner wall of the car is arranged parallel to its corresponding mounting plate.

[0020] Furthermore, the inner wall of the car is arranged parallel to its corresponding pivot.

[0021] Furthermore, the rotating shaft is arranged in a horizontal direction.

[0022] Furthermore, the partition plate is provided with a clearance notch for avoiding the rack.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] (1) The present invention uses a roller assembly for contact between the partition and the car, so that the partition does not directly contact the inner wall of the car. Therefore, the distance between the inner wall of the car and the partition can be increased, making it easier to use tools to clean the slag stuck between the inner wall of the car and the partition.

[0025] (2) By setting up roller assemblies, the rollers of the roller assemblies contact the inner wall of the car. Roller assemblies are set near the four sides of the bottom of the partition to correspond to the four inner walls of the car. Each set of roller assemblies has four rollers distributed in a rectangular shape, which can restrict the movement direction of the partition and guide the partition to move up and down in the car.

[0026] (3) The present invention can reduce the friction between the partition and the inner wall of the car by setting the roller assembly, thereby reducing the wear between the two. Attached Figure Description

[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1-4 As shown, this embodiment provides a double-deck mining elevator car, including:

[0034] The car 1 has a partition 2 inside, which divides the car 1 into an upper and a lower level. The distance between the partition 2 and the side wall of the car 1 is greater than 1 cm. The partition 2 can be moved up and down to adjust the space of the upper and lower levels of the car 1. The distance between the partition 2 and the side wall of the car 1 is greater than 1 cm, which makes it easy to clean the slag between the partition 2 and the side wall of the car 1 using tools, such as a stick.

[0035] A lifting assembly is located above the partition 2 and is used to move the partition 2 up and down.

[0036] At least five sets of roller assemblies are installed on the bottom surface of the partition 2 and correspond to the side walls of the car 1. At least two sets of roller assemblies correspond to the side walls of the car 1 with doors, and at least one set of roller assemblies corresponds to the other three side walls of the car 1. Each roller assembly includes a mounting plate 3 and four rollers 4. The four rollers 4 are rotatably mounted on the four corners of the mounting plate 3 via a rotating shaft 5. The mounting plate 3 is fixed to the bottom surface of the partition 2. The rollers 4 roll in contact with their corresponding side walls. By setting four rollers 4 on the mounting plate 3 and distributing the four rollers 4 in a rectangular pattern, the stability of the partition 2 moving up and down in the car 1 is improved.

[0037] In this embodiment, in order to improve the stability of the partition 2 lifting and lowering, eight sets of roller assemblies can be provided at the bottom of the partition 2. The eight sets of roller assemblies are evenly distributed on the four sides of the bottom of the partition 2, with two sets of roller assemblies provided on each side. The four sides of the partition 2 correspond to the four sides of the car 1, and the two sets of roller assemblies provided on each side also correspond to the side wall of the car 1 corresponding to that side.

[0038] This utility model uses a roller assembly for contact between the partition 2 and the car 1, so that the partition 2 does not directly contact the inner wall of the car 1. Therefore, the distance between the inner wall of the car 1 and the partition 2 can be increased, making it easier to use tools to clean the slag stuck between the inner wall of the car 1 and the partition 2.

[0039] This utility model sets up a roller assembly, in which the rollers 4 of the roller assembly contact the inner wall of the car 1. Roller assemblies are set near the four sides of the bottom of the partition 2 to correspond to the four inner side walls of the car 1. Each set of roller assemblies has four rollers 4 arranged in a rectangular shape, which can restrict the movement direction of the partition 2 and guide the partition 2 to move up and down in the car 1.

[0040] The present invention can reduce the friction between the partition 2 and the inner wall of the car 1 by setting the roller assembly, thereby reducing the wear between the two.

[0041] Specifically, the lifting assembly includes a winch 6, which is installed on the top of the car 1. The top of the car 1 has a through hole 7. The wire rope 8 of the winch 6 passes through the through hole 7 and is connected to the partition 2 to drive the partition 2 to move up and down. The winch 6 is existing technology. When the winch 6 is winding up, the wire rope 8 of the winch 6 can pull the partition 2 up. When the winch 6 is unwinding, the partition 2 will descend under the action of gravity.

[0042] Furthermore, a rack 9 is provided on the inner side wall of the car 1 in the vertical direction, and a locking chamber 10 is provided at the bottom of the partition 2, and a self-locking component is provided in the locking chamber 10;

[0043] The self-locking assembly includes a gear 11, a ratchet 12, a pawl 13 that engages with the ratchet 12, a mounting shaft 14, a tension spring 15, and an electromagnet 16. The mounting shaft 14 is rotatably mounted inside the locking chamber 10. The gear 11 and the ratchet 12 are coaxially fixed on the mounting shaft 14. The gear 11 meshes with the rack 9. The pawl 13 has two ends: a first end and a second end. The second end is rotatably connected to the locking chamber 10. When the car 1 descends, the ratchet 12 rotates in the direction of... In the first direction, when the car 1 rises, the ratchet 12 rotates in the second direction. The two ends of the tension spring 15 are respectively connected to the first end and the locking chamber 10 to pull the pawl 13, causing the first end to approach and engage with the ratchet 12. When the ratchet 12 engages with the pawl 13, the pawl 13 prevents the ratchet 12 from rotating in the first direction. The electromagnet 16 is installed on the inner wall of the locking chamber 10 to attract the first end, causing the... The first end is away from the ratchet 12. Through the rack 9, in conjunction with the gear 11, ratchet 12, pawl 13, tension spring 15, and electromagnet 16, the partition 2 can be locked to prevent it from descending. Specifically, when the partition 2 needs to move, the electromagnet 16 is energized. At this time, the electromagnet 16 attracts the first end of the pawl 13, and the winch 6 drives the partition 2 upward. During the upward movement of the partition 2, due to the interaction between the rack 9 and the gear 11, the gear 11 is driven to rotate, which in turn drives the ratchet 12. 2. When the ratchet 12 rotates in the second direction, the jammed pawl 13 will be released. After the pawl 13 is released, it will be attracted by the electromagnet 16. When the pawl 13 is attracted by the electromagnet 16, the partition 2 can rise and fall freely. After the partition 2 has finished rising and falling, the electromagnet 16 is de-energized. Under the action of the tension spring 15, the first end of the pawl 13 approaches the ratchet 12 and contacts the ratchet 12. At this time, if the partition 2 falls, the ratchet 12 will jam the pawl 13, preventing the partition 2 from falling further.

[0044] Furthermore, the edge of the partition 2 is provided with a brush 17, which can fill the gap between the car 1 and the partition 2 to prevent slag from falling into the gap between the partition 2 and the car 1.

[0045] Furthermore, the inner wall of the car 1 is arranged parallel to its corresponding mounting plate 3.

[0046] Furthermore, the inner wall of the car 1 is arranged parallel to its corresponding rotating shaft 5.

[0047] Furthermore, the rotating shaft 5 is arranged in a horizontal direction.

[0048] Furthermore, the partition plate 2 is provided with a clearance notch 18 for avoiding the rack 9.

[0049] It should be noted that although the present invention has been disclosed above with specific embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
