Description

Technical Field

[0001] This utility model belongs to the field of elevator car technology, and in particular relates to a freight elevator car. Background Technology

[0002] An elevator car is a box-shaped space used to carry and transport people and goods in an elevator. It is the main functional component of an elevator, connected to the traction machine via traction steel cables to achieve vertical movement. Specifically, a freight elevator car is the box-shaped space used to carry and transport goods in a freight elevator, and usually allows personnel to accompany the passenger during operation.

[0003] For example, CN214733660U discloses a freight elevator car, including a freight elevator body, a limiting device and a lifting mechanism installed inside the freight elevator body. The limiting device includes a C-shaped limiting box installed inside the freight elevator body, with a dual-axis motor inside the C-shaped limiting box. The output shaft of the dual-axis motor is connected to a transmission shaft, and a drive wheel is installed at one end of the transmission shaft. The drive wheel is connected to a driven wheel via a conveyor belt, and a first threaded screw is installed at the center of the driven wheel. A limiting rod is threadedly connected to the first threaded screw. In this utility model, through the limiting device and the corresponding lifting mechanism, after a trolley enters the freight elevator, the driving limiting plate extends to limit the trolley, preventing damage to the elevator caused by the trolley or the goods on the trolley during elevator movement. In summary, this achieves the beneficial effects of convenient transportation and improved safety and efficiency.

[0004] The above-mentioned patent has the following defects in use:

[0005] The size of trolleys varies in actual use, and the position and spacing of their bottom rollers also vary accordingly. The limiting device is difficult to adjust to trolleys with different wheel gauges and can only be used for trolleys with a single fixed wheel gauge, which has low practicality. Therefore, this utility model proposes an elevator car for carrying goods. Utility Model Content

A moving mechanism enables a pair of I-beams and four pairs of clamping plates to move in opposite directions along the left-right axis, approaching the trolley rollers. This allows for effective clamping and fixing of rollers with different lateral wheelbases. A clamping adjustment mechanism enables two pairs of clamping plates to move along the I-beams in the front-back direction, adjusting their clamping position according to the longitudinal wheelbase of different rollers. This facilitates clamping and fixing of rollers with varying wheelbases, expanding its application range and improving its practicality.

[0013] Furthermore, a camera and a transparent protective cover are fixedly connected to the inner wall of the car body near the top, and the transparent protective cover is fitted over the outside of the camera. The bottom inner end of the protective frame plate is rounded.

[0014] Furthermore, the outer wall of the bidirectional threaded rod is provided with an external thread, and the threads of the external thread are opposite in direction. Threaded through holes are drilled between the two ends of the pair of movable blocks, and the movable blocks are threadedly connected to the bidirectional threaded rod through the threaded through holes.

[0015] Furthermore, telescopic curtains are fixedly connected to both ends of the inner wall of the movable channel, and the top and bottom ends of the telescopic curtains are in contact with the inner top and bottom ends of the movable channel, respectively.

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

[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0035] Please see Figures 1-6 As shown, a freight elevator car of this utility model includes:

[0036] The car body 1 has a protective frame plate 2 fixedly connected to its inner wall. A T-shaped frame 5 is fixedly connected inside the protective frame plate 2, and a pair of I-shaped rods 9 are provided on one side of the T-shaped frame 5.

[0037] The moving mechanism 6 is set on the T-shaped frame 5 and is used to drive a pair of I-shaped rods 9 to move closer to or away from the trolley rollers.

[0038] A pair of clamping and adjusting mechanisms 8 are provided on the outer wall of the I-shaped rod 9, and the clamping and adjusting mechanisms 8 are used for clamping and fixing the trolley rollers;

[0039] The moving mechanism 6 includes a bidirectional threaded rod 601. Both ends of the bidirectional threaded rod 601 are rotatably connected to the inner wall of the T-shaped frame 5 via bearings. A motor 602 is fixedly connected to the inner wall of the T-shaped frame 5. Pulleys 603 are fixedly connected to the outer wall of the bidirectional threaded rod 601 and the output end of the motor 602. A transmission belt 604 is connected between the outer walls of the pair of pulleys 603. A pair of moving blocks 605 are threadedly connected to the outer wall of the bidirectional threaded rod 601. An L-shaped plate 606 is provided on one side of each pair of moving blocks 605. A pair of moving through slots 607 are chiseled on one side of the T-shaped frame 5. The side of the L-shaped plate 606 closest to the moving block 605 passes through the moving through slot 607 and is fixedly connected to one end of the moving block 605. The side of the pair of L-shaped plates 606 furthest from the moving block 605 is fixedly connected to one end of a pair of I-shaped rods 9.

[0040] In the specific implementation process, after the trolley carrying the goods moves into the elevator car body 1, the drive motor 602 is activated. The motor 602 drives the bidirectional threaded rod 601 to rotate through the transmission action between a pair of pulleys 603 and the transmission belt 604. This causes a pair of moving blocks 605 to move towards each other under the rotation of the bidirectional threaded rod 601, and drives a pair of L-shaped plates 606 to move towards each other along a pair of moving through slots 607. This facilitates the movement of a pair of I-shaped rods 9 and the clamping adjustment mechanism 8 closer to the trolley rollers, so that they can be effectively clamped and fixed when facing rollers with different lateral wheel spacings. After the elevator car body 1 drives the trolley and goods to rise or fall to the target floor, the trolley carrying the goods is pulled out of the elevator. At this time, the motor 602 drives the bidirectional threaded rod 601 to rotate in the opposite direction, causing the pair of moving blocks 605 to move away from each other. This movement is also caused by the pair of L-shaped plates 606, which drive the pair of I-shaped rods 9 and the clamping adjustment mechanism 8 to move away from the trolley rollers, thus avoiding obstruction of the trolley's exit from the elevator.

[0041] Among them, a camera 3 and a transparent protective cover 4 are fixedly connected to the inner wall of the car body 1 near the top, and the transparent protective cover 4 is fitted on the outside of the camera 3. The inner bottom end of the protective frame plate 2 is rounded.

[0042] Camera 3 can monitor the situation inside the car body 1 in real time to facilitate subsequent safety management. When tubular, strip, or rod-shaped goods enter the car body 1, the top of the goods may accidentally touch the camera 3 if handled carelessly. The transparent protective cover 4 can cover and protect the camera 3 to prevent damage. In addition, the inner bottom of the protective frame plate 2 is rounded to facilitate the entry of the trolley wheels.

[0043] The outer wall of the bidirectional threaded rod 601 is provided with an external thread, and the threads of the external thread are opposite in direction. A threaded through hole is drilled between the two ends of a pair of moving blocks 605, and the moving blocks 605 are threadedly connected to the bidirectional threaded rod 601 through the threaded through hole.

[0044] The bidirectional threaded rod 601 is provided with a pair of external threads in opposite directions, which can drive the moving block 605 to move towards or away from each other with the assistance of the threaded through hole when rotating.

[0045] The inner walls of the movable channel 607 are fixedly connected to telescopic curtains 7 at both ends, and the top and bottom ends of the telescopic curtains 7 are in contact with the inner top and bottom ends of the movable channel 607, respectively. The ends of the pair of telescopic curtains 7 that are close to each other are fixedly connected to the outer wall of the L-shaped plate 606.

[0046] By setting the telescopic curtain 7, the movable channel 607 can be sealed, and when the L-shaped plate 606 moves, it can move in coordination with the corresponding telescopic movement to maintain the seal of the movable channel 607, so that dust is not easy to enter the interior of the T-shaped frame 5 through the movable channel 607. Specific Implementation Example 2:

[0048] Please see Figure 1 , Figure 3 and Figure 4As shown, in a preferred embodiment, the clamping adjustment mechanism 8 includes a pair of electric telescopic rods 801. The ends of the pair of electric telescopic rods 801 that are far apart are fixedly connected to the inner wall of the I-shaped rod 9. Two pairs of magnet blocks 802 are sleeved on the outer wall of the I-shaped rod 9, and a pair of round rods 807 are fixedly connected between the opposite sides of the pair of magnet blocks 802. One end of the electric telescopic rod 801 is fixedly connected to one end of the magnet block 802 located on the outer side. An electromagnet 803 is sleeved between the outer walls of the pair of round rods 807. Two pairs of magnetic sleeve plates 804 are sleeved on the outer wall of the I-shaped rod 9, and the surface of the magnetic sleeve plates 804 is provided with a magnetic layer. The two pairs of magnetic sleeve plates 804 are respectively sleeved on the outer walls of the pair of round rods 807. A clamping plate 805 is fixedly connected to one side of each pair of magnetic sleeve plates 804.

[0049] In the specific implementation process, a pair of electric telescopic rods 801 drive a pair of magnets 802 and a round rod 807 to move along the I-shaped rod 9 via the outer magnets 802. This causes a pair of magnetic sleeves 804, clamps 805, and an electromagnet 803 to move, thereby adjusting the clamping position according to the longitudinal wheel track of different rollers. This causes the pair of clamps 805 to correspond to the rollers. Then, driven by the L-shaped plate 606 and the I-shaped rod 9, the rods move laterally and extend to both sides of the rollers. Immediately afterward, the energized electromagnet 803 generates magnetism, attracting the pair of magnetic sleeves 804 to move towards each other, which in turn causes the pair of clamps 805 to move towards each other. This clamps and fixes the four rollers of the trolley, keeping the rollers stable and ensuring the stability of the trolley and the goods. This method is suitable for clamping and fixing rollers with different wheel tracks, effectively improving its practicality.

[0050] In this pair of magnetic sleeves 804, the opposite sides of the pair of magnetic plates 804 are in contact with the opposite sides of the pair of magnet blocks 802, and the magnetism of the electromagnet 803 is stronger than that of the magnet blocks 802.

[0051] In the initial state, the electromagnet 803 is not energized. At this time, a pair of magnetic sleeves 804 are attracted by the magnet 802. After the electromagnet 803 is energized and generates magnetism, since the magnetism of the electromagnet 803 is stronger than that of the magnet 802, it attracts a pair of magnetic sleeves 804 to move towards each other, approach the electromagnet 803 and come into contact with it.

[0052] Among them, wear-resistant rubber pads 806 are fixedly connected to the opposite sides of a pair of clamps 805.

[0053] The wear-resistant rubber pad 806 provides cushioning when the pair of clamping plates 805 come into contact with and hold the rollers, thus preventing damage to the rollers.

[0054] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0055] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0056] The working principle of this utility model is as follows:

[0057] In use, after the trolley carrying goods moves into the car body 1, the drive motor 602 is activated. The motor 602 drives the bidirectional threaded rod 601 to rotate via a transmission belt 604 and a pair of pulleys 603. This causes a pair of moving blocks 605 to move towards each other under the rotation of the bidirectional threaded rod 601, and also causes a pair of L-shaped plates 606 to move towards each other along a pair of moving slots 607. This facilitates the movement of a pair of I-shaped rods 9 and clamping plates 805 closer to the trolley rollers. During this approach, a pair of electric telescopic rods 801, through the outer magnets 802, drive a pair of magnets 802. The round rod 807 moves along the I-shaped rod 9, causing it to drive a pair of magnetic sleeves 804, clamping plates 805, and electromagnet 803 to move. This allows the clamping positions of the rollers to be adjusted according to their longitudinal wheel spacing, causing the pair of clamping plates 805 to correspond to the rollers. Then, driven by the L-shaped plate 606 and the I-shaped rod 9, the clamping plates move laterally to both sides of the rollers. Immediately afterward, the energized electromagnet 803 generates magnetism, attracting the pair of magnetic sleeves 804 to move towards each other, which in turn drives the pair of clamping plates 805 to move towards each other. This clamps and fixes the four rollers of the trolley, keeping the rollers stable and thus keeping the trolley and goods stable.
