TECHNICAL FIELD

[0001] The present application relates to the field of elevator technology, in particular to a cargo elevator anti-collision device. BACKGROUND

[0002] The cargo elevator belongs to a kind of lift elevator, and its characteristics are that it often transports goods in high-rise buildings, has high load capacity and large car area, and the car door is larger than that of general passenger elevators. In actual use scenarios, it is not easy to directly carry goods, and workers often push wheeled goods into the cargo elevator, but when the cargo elevator is running, the workers often do not hold the goods well, causing the wheeled goods to collide with the car wall or car door, causing the cargo elevator to stop suddenly, which needs to call for elevator rescue, which is very troublesome, and even some collisions can cause damage to the cargo elevator, affecting its service life.

[0003] Therefore, in order to reduce the impact of goods on the inner wall of the cargo elevator car during operation, the current solution is to set a limiting device at the bottom of the cargo elevator car, so that the goods entering the cargo elevator are fixed and will not be pushed out due to the operation of the cargo elevator. For example, a kind of anti-collision device for people and goods elevator and people and goods elevator is disclosed in Chinese patent No. CN114261870A, published on April 1, 2022, which is set by rotating the blocking piece. When the anti-collision device is installed in the external people and goods elevator, the blocking piece does not need to extend outside the people and goods elevator when blocking or opening the people and goods elevator, avoiding the increase of the use space.

[0004] However, in actual use, some goods do not need to be blocked by the blocking piece, such as some non-wheeled objects. At this time, the blocking piece needs to be stored on one side to make more space inside the car, but in the technical solution of the invention, on the one hand, the blocking piece is a fixed length rod, which is not convenient to store, and on the other hand, when storing the blocking piece, it can only be lifted up to one side by rotating it upwards, which has the risk of falling at any time, and the personnel inside the car need to hold it with their hands all the time, which is very troublesome.

DETAILED DESCRIPTION

[0031] The application will be further described below in conjunction with the drawings.

[0032] The specific embodiments are merely illustrative of the application, and are not intended to limit the application. Those skilled in the art can make modifications to the embodiments without creative contribution, as long as the modifications are within the scope of the claims of the application.

[0033] Embodiment one, as shown, a goods elevator anti-collision device, comprising a storage rack unit 1, and a fixed rack unit 2, further comprising a telescopic rod unit 3 arranged on the storage rack unit 1 and used for clamping the fixed rack unit 2 to block the goods in the goods elevator, and a rotating block unit 4 arranged on the storage rack unit 1 and used for mounting the telescopic rod unit 3. Figure 1 As shown, the storage rack unit 1 and the fixed rack unit 2 are arranged on the left and right sides of the car respectively, the telescopic rod unit 3 is fixed on the storage rack unit 1 through the rotating block unit 4, and the other end is clamped on the fixed rack unit 2. When the goods enter the goods elevator, the telescopic rod unit 3 is first opened upward in a direction perpendicular to the fixed rack unit 2 to allow the goods to pass through the goods elevator, and then the telescopic rod unit 3 is closed downward after the goods enter the goods elevator to lock the goods, thereby avoiding that some goods with wheels at the bottom (such as electric bicycles) collide with the goods elevator door and cause the goods elevator to malfunction. Figure 1 In addition, in the embodiment, the telescopic rod unit 3 has a telescopic function, and the rotating block unit 4 has a rotating function. In the case that the above device is not used for a long time, the telescopic rod unit 3 can be stored. Specifically, the telescopic rod unit 3 is first compressed, then the telescopic rod unit 3 is lifted, the rotating block unit 4 is rotated to make the telescopic rod unit 3 enter the storage rack unit 1 to complete the storage. Compared with simply lifting the telescopic rod unit 3, this storage method saves more space, and the telescopic rod unit 3 will not accidentally fall and injure the passengers in the goods elevator.

[0034]

[0035] ​Of course, the inventor has once considered using a rope instead of the telescopic rod unit 3, the storage function of the rope is better, which can be straightened or wound, but the elasticity of the rope itself is too high, when it plays a blocking role to the goods, the goods have often hit the side of the car, setting the rope away from the car can also solve this problem, but it will greatly limit the placement space of the goods, which is not feasible. And fixing the rope, the staff needs to pull the rope tightly at the other end, which not only needs a lot of effort, but also may not have enough space for the staff to operate in the car, and it takes a lot of time to tie the rope, the elevator continues to stay at one floor, which will cause dissatisfaction of passengers and increase the waiting time of passengers above. In summary, only the telescopic rod is set to block the goods from rushing out of the goods elevator.

[0036] The specific structure of the telescopic rod unit 3 and the rotating block unit 4 will be described below.

[0037] <About telescopic rod unit 3>

[0038] As shown in Figure 7 , the telescopic rod unit 3 includes an inner rod 301 arranged on the rotating block 401, an outer rod 302 for clamping the fixed frame unit 2, a movable rod 303 connecting the inner rod 301 and the outer rod 302, and a movable rod groove 304 arranged on the outer rod 302 and used for mounting the movable rod 303. The movable rod 303 is fixed at both ends of the inner rod 301 and the outer rod 302, and realizes the telescopic function of the telescopic rod unit 3 by sliding in the movable rod groove 304. In order to prevent the movable rod 303 from sliding out of the movable rod groove 304 during telescoping, a limiting sliding block 305 is arranged at the inner end of the movable rod 303, and a plurality of limiting fixed blocks 306 are arranged near the slot of the movable rod groove 304. By blocking the limiting sliding block 305, the movable rod 303 is prevented from sliding out of the movable rod groove 304 during telescoping. In addition, a reset spring 307 is added in the movable rod groove 304, which lifts the limiting sliding block 305 so that in the natural state, the outer rod 302 will try to move away from the inner rod 301, so that the telescopic rod unit 3 as a whole reaches the longest state, so as to clamp the fixed frame unit 2.

[0039] Figure 8 Another telescopic rod unit 3 scheme is given in the

[0040] <About storage rack unit 1 and fixed frame unit 2>

[0041] As shown in Figure 2 , 9 , the storage rack unit 1 includes a car bottom column 101, a storage groove 102 arranged on the car bottom column 101, and a guide groove 106 communicating with the storage groove 102 and used for mounting the telescopic rod unit 3; the fixed rack unit 2 includes a fixed bottom column 201 and a fixed groove 202 arranged on the fixed bottom column 201. The guide groove 106 and the fixed groove 202 are arranged in alignment, i.e. on the same straight line parallel to the car wall. When it is needed to close the telescopic rod unit 3, the inner rod 301 is only needed to be placed down in alignment with the guide groove 106, and the outer end of the outer rod 302 can be directly aligned with the fixed groove 202 and clamped into it to achieve locking. In addition, the inner end surface of the fixed groove 202 can also lift the end surface of the outer rod, so that the telescopic rod unit 3 stops elongation and is kept at a length distance between the storage rack unit 1 and the fixed rack unit 2, so as to block the goods.

[0042] In addition, as shown in Figure 3 , the storage rack unit 1 further includes an inner sliding groove 103 arranged at the bottom of the storage groove 102 and used for mounting the rotating block unit 4. To store the telescopic rod unit 3 into the storage rack unit 1, it is only needed to compress the telescopic rod unit 3 to be shorter than the storage groove 102, and then put the telescopic rod unit 3 into the storage groove 102 to achieve storage. The limitation of the storage groove 102 body makes the telescopic rod unit 3 not to expand in length when being stored. The purpose of this design is to consider the actual space limitation of the goods elevator. In order to facilitate the transportation of goods, the goods elevator door is made large, which leads to the telescopic rod unit 3 being very long, even longer than the storage rack unit 1. If it is not designed to be a retractable structure, it will face the problem of turning to the other side and being pushed against the car wall. Therefore, the above telescopic structure is provided to solve the problem.

[0043] In addition, the limitation of the telescopic rod unit 3 by the storage groove 102 alone is unstable. Because of the existence of the reset spring 307, the telescopic rod unit 3 itself always has a tendency to expand outward. Once the goods elevator jolts, the telescopic rod unit 3 may slide out of the storage groove 102. Therefore, in the present embodiment, as shown in Figure 4As shown, the storage rack unit 1 also includes a locking block 105 disposed on the storage slot 102; the telescopic rod unit 3 also includes a lower locking block 308 disposed on the outer rod 302 and used to engage the upper locking block 105, and a pull handle 309 disposed on the outer rod 302. When installing the telescopic rod unit 3, first use the pull handle 309 to pull the outer rod 302 towards the inner rod 301, compress the telescopic rod unit 3, until the upper locking block 105 is misaligned with the lower locking block 308, then put the telescopic rod unit 3 into the storage slot 102, at this time release the pull handle 309, then the lower locking block 308 automatically pops under the upper locking block 105 and locks with it. In this way, regardless of how the elevator shakes, without operating the pull handle 309, the telescopic rod unit 3 cannot be separated from the storage slot 102. In addition, the outer end of the pull handle 309 is provided with an arc-shaped groove for hand holding, which facilitates the staff to come down to compress the telescopic rod unit 3 into the storage slot 102, or take out the telescopic rod unit 3 from the storage slot 102.

[0044] In addition, a cover plate or cloth can also be provided on the storage slot 102, when the telescopic rod unit 3 is not stored, cover the top of the storage slot 102 to avoid dust entering and affecting the smoothness of future storage of the telescopic rod unit 3. The telescopic function of the telescopic rod unit 3 can also make the storage slot 102 very short, avoiding the entry of too much dust.

[0045] <About the rotating block unit 4>

[0046] As shown in Figure 5 , 6 , the rotating block unit 4 includes a rotating block 401 for installing the telescopic rod unit 3, and a sliding column 402 disposed on the rotating block 401 and used to insert into the inner sliding slot 103. The outer shape of the rotating block 401 is combined by a sphere and a cylinder, the end face of the cylinder is connected with the inner rod 301, the sphere is provided with a movable groove 404, the opening direction of the movable groove 404 is from top to bottom, the sliding column 402 is connected to the sphere by inserting into the movable groove 404, then through the bearing 405 reserved on the hole, the end face of the bearing 405 is connected with the inner groove face of the movable groove 404, so that the sphere can rotate along the axis of the extension direction of the bearing 405, when the sphere rotates, the telescopic rod unit 3 connected thereto can move upwards, thereby opening the restriction and allowing goods to enter and exit the elevator.

[0047] Meanwhile, the lower end of the sliding column 402 is inserted into the inner sliding groove 103 arranged on the bottom surface of the storage groove 102, so that the ball can also rotate along the axis of the extension direction of the sliding column 402, when the ball rotates, the telescopic rod unit 3 connected thereto can rotate along the plane of the elevator bottom, in this way, the steps of lifting up first, then rotating towards the storage rack unit 1 and finally putting down when the telescopic rod unit 3 is stored are realized. Meanwhile, in order to avoid the sliding column 402 from sliding out of the storage groove 102 when rotating, the blocking block 104 is arranged at the slot of the inner sliding groove 103, and the sliding disc 403 which is engaged with the sliding column 402 is arranged on the sliding column 402, so as to ensure that the sliding column 402 will not slide out of the storage groove 102 when rotating.

[0048] In addition, the terms "vertical", "horizontal", "top", "bottom", "front", "back", "upper", "lower", "inner", "outer" and the like as mentioned in the embodiments of the present application indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product is usually placed in use, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
