Description

Technical Field

[0001] The invention belongs to the technical field of lifting slings, and in particular relates to a sling and a sling frame thereof. Background Art

[0002] The existing lifting equipment for lifting battery boxes usually adopts traditional arc-shaped hooks, but the anti-dropping effect of the traditional arc-shaped hooks is poor. If the anti-dropping structure is installed on the arc-shaped hooks, a larger operating space and a larger dedicated lifting hole are required, which is inconvenient to operate and has high costs. Moreover, the lifting points of traditional lifting equipment are usually fixed, which is difficult to adapt to lifting objects with different centers of gravity or large center of gravity offsets.

[0003] The invention patent with the authorization announcement number CN 217732423U (publication date: 2022.11.04) provides a power battery hoist, which includes a hoist frame, a sling (wire rope) and a hook connected to the sling. The hook includes a lifting ear body and a limit (self-locking) block. The limit block is elliptical and adapted to the battery box lifting hole. The rotating hook extends the limit block into the battery box lifting hole to achieve the connection between the hook and the battery box, thereby improving the lifting efficiency. In addition, the sling is wrapped around the sling frame, and the sling frame is provided with spaced limit plates. The sling can move between the limit plates, and the distance between two adjacent slings can be adjusted in a small range to adapt to the lifting of battery boxes with different centers of gravity.

[0004] Although the above-mentioned sling can adapt to battery boxes with different centers of gravity, the sling and the sling frame are movable. During the lifting process, relative sliding is likely to occur between the sling and the sling frame, which is insufficient in safety. Summary of the invention

[0005] The object of the present invention is to provide a sling frame to solve the technical problem of insufficient safety caused by relative sliding between the sling and the frame in the prior art. The object of the present invention is also to provide a sling to solve the same technical problem as above.

[0006] To achieve the above purpose, the technical solution of the sling frame provided by the present invention is:

[0007] A sling frame includes a frame body, the battery sling frame also includes at least one limiting connector, the frame body is provided with at least two connection positions for limiting cooperation with a single limiting connector, and the limiting connector is provided with a sling installation position for installing a sling.

[0008] The beneficial effect is that the present invention improves the sling frame in the prior art. In the process of lifting a battery box or other lifting objects, the position of the sling can be changed by connecting the limit connector to different connection positions to adapt to lifting objects with different centers of gravity and different lifting points. Since the limit connector and the frame body are limit connected, no relative movement occurs, thus ensuring stability during the lifting process, thereby improving safety during the lifting process.

[0009] As a further improvement, the position-limiting connector includes an upper connector having a mating surface for mating with an upper surface of the frame body.

[0010] The beneficial effect is that compared with connecting the limiting connector to the side of the frame body, the upper surface of the frame body can be used to provide stable support for the limiting connector, further improving the reliability of the limiting connection between the limiting connector and the frame body.

[0011] As a further improvement, side guide members are connected to both sides of the upper connecting member, and the upper connecting member and the side guide members together enclose a guide channel for adjusting the position along the frame body.

[0012] The beneficial effect is that the side guide member plays a guiding and limiting role on the limit connector, which not only facilitates the guided movement of the limit connector along the frame body, but also limits the swing of the limit connector relative to the frame body, further improving the connection reliability of the limit connector and the frame body.

[0013] As a further improvement, the side guide member is formed by an integral side guide plate with a "U"-shaped cross section, and the bottom of the side guide plate forms the sling installation position.

[0014] The beneficial effect is that the integrally formed side guide plate and the upper connecting piece are connected and installed with high efficiency and also have good strength.

[0015] As a further improvement, the inner side wall of the side guide plate is connected to a guide bottom plate, the guide bottom plate, the side guide plate and the upper connecting piece are combined to form a closed guide hole, and the guide channel is formed by the guide hole.

[0016] The beneficial effect is that the guide hole forms a full cover for the frame body, that is, an all-round restriction, which prevents the limiting connector from excessively moving upward, and further improves the reliability of the limiting connection between the limiting connector and the frame body.

[0017] As a further improvement, the connection position includes a limiting hole extending in the up-down direction of the frame body, and the upper connecting member is limitedly matched with the limiting hole through a limiting pin.

[0018] The beneficial effect is that only the limit hole needs to be set in the frame body, which is convenient for processing. At the same time, the limit connector can be adjusted by sliding with the frame body and pulling out the limit pin, which has high efficiency.

[0019] As a further improvement, the upper connecting member is provided with an observation channel corresponding to the position of the limiting hole for observing the position of the limiting hole.

[0020] The beneficial effect is that the limit pin can be inserted and removed while observing the position of the limit hole, which further improves the efficiency.

[0021] As a further improvement, the vertical projection width of the observation channel is not greater than the vertical projection width of the limiting hole.

[0022] The beneficial effect is that, while ensuring the observation effect, the area of ​​the connection and matching surface between the upper connecting piece and the frame body will not be reduced too much, thereby ensuring the supporting effect of the frame body on the upper connecting piece.

[0023] As a further improvement, the upper connecting member is a rectangular tube, a long groove is provided on the bottom wall of the rectangular tube, and the long groove forms the observation channel.

[0024] The beneficial effects are: on the one hand, the rectangular tube has high strength and light weight, which meets the lightweight and strength requirements of the sling frame. On the other hand, the opening and internal space of the rectangular tube can be used to observe the position of the limit hole. Only a long groove is required on the bottom wall to ensure that the staff can observe the limit hole, that is, other parts except the bottom wall are still intact. Therefore, the overall strength of the limit connector is guaranteed and the observation function is realized.

[0025] To achieve the above purpose, the technical solution of the sling provided by the present invention is:

[0026] A sling includes a sling connected to a sling frame, the sling frame includes a frame body, the battery sling frame also includes at least one limiting connector, the frame body is provided with at least two connection positions for limiting cooperation with a single limiting connector, the limiting connector is provided with a sling installation position for installing the sling.

[0027] The beneficial effect is that the present invention improves the sling frame of the sling in the prior art. In the process of lifting a battery box or other lifting objects, the position of the sling can be changed by connecting the limit connector to different connection positions to adapt to the lifting objects with different centers of gravity and different lifting points. Since the limit connector and the frame body are limit connected, no relative movement occurs, thus ensuring the stability during the lifting process, thereby improving the safety during the lifting process.

[0028] As a further improvement, the position-limiting connector includes an upper connector having a mating surface for mating with an upper surface of the frame body.

[0029] The beneficial effect is that compared with connecting the limiting connector to the side of the frame body, the upper surface of the frame body can be used to provide stable support for the limiting connector, further improving the reliability of the limiting connection between the limiting connector and the frame body.

[0030] As a further improvement, side guide members are connected to both sides of the upper connecting member, and the upper connecting member and the side guide members together enclose a guide channel for adjusting the position along the frame body.

[0031] The beneficial effect is that the side guide member plays a guiding and limiting role on the limit connector, which not only facilitates the guided movement of the limit connector along the frame body, but also limits the swing of the limit connector relative to the frame body, further improving the connection reliability of the limit connector and the frame body.

[0032] As a further improvement, the side guide member is formed by an integral side guide plate with a "U"-shaped cross section, and the bottom of the side guide plate forms the sling installation position.

[0033] The beneficial effect is that the integrally formed side guide plate and the upper connecting piece are connected and installed with high efficiency and also have good strength.

[0034] As a further improvement, the inner side wall of the side guide plate is connected to a guide bottom plate, the guide bottom plate, the side guide plate and the upper connecting piece are combined to form a closed guide hole, and the guide channel is formed by the guide hole.

[0035] The beneficial effect is that the guide hole forms a full cover for the frame body, that is, an all-round restriction, which prevents the limiting connector from excessively moving upward, and further improves the reliability of the limiting connection between the limiting connector and the frame body.

[0036] As a further improvement, the connection position includes a limiting hole extending in the up-down direction of the frame body, and the upper connecting member is limitedly matched with the limiting hole through a limiting pin.

[0037] The beneficial effect is that only the limit hole needs to be set in the frame body, which is convenient for processing. At the same time, the limit connector can be adjusted by sliding with the frame body and pulling out the limit pin, which has high efficiency.

[0038] As a further improvement, the upper connecting member is provided with an observation channel corresponding to the position of the limiting hole for observing the position of the limiting hole.

[0039] The beneficial effect is that the limit pin can be inserted and removed while observing the position of the limit hole, which further improves the efficiency.

[0040] As a further improvement, the vertical projection width of the observation channel is not greater than the vertical projection width of the limiting hole.

[0041] The beneficial effect is that, while ensuring the observation effect, the area of ​​the connection and matching surface between the upper connecting piece and the frame body will not be reduced too much, thereby ensuring the supporting effect of the frame body on the upper connecting piece.

[0057] The present invention is further described in detail below in conjunction with embodiments.

[0058] Specific embodiment 1 of the sling provided by the present invention:

[0059] In order to meet the requirement of changing the position of the lifting point of the sling while improving the safety of the sling during the lifting process, the present invention provides a limiting connector between the sling and the frame body based on the design concept that the connection position of the sling is adjustable and fixed. The limiting connector can be connected to different positions of the frame body and fixed at the connection position.

[0060] The overall structure of the sling provided in this embodiment can be referred to Figure 1 , including a sling frame, the sling frame is connected to a sling 3, and the sling 3 is connected to a hook 4. During lifting, the hook 4 is connected to the lifting object, such as a battery box 5, and the sling frame is connected to a crane or other forms of cranes. Among them, the sling 3 can be a chain, a wire rope, a braided rope, etc., which can achieve the connection between the sling frame and the hook.

[0061] like Figure 2-Figure 4 As shown, the hook 4 includes a hook shaft 401, which is used to be plugged into the lifting hole 501 of the battery box 5. A self-locking block 402 is provided at the end of the hook shaft 401. The lifting hole 501 is an elliptical hole, and the self-locking block 402 is also an elliptical structure. After the self-locking block 402 passes through the lifting hole 501 and rotates 90 degrees, the long axis of the self-locking block 402 is parallel to or coincides with the short axis of the lifting hole 501, so as to achieve self-locking and anti-slipping. This process can be automatically completed during lifting, thus ensuring the safety of lifting and having high efficiency.

[0062] The hook shaft 401 is connected to the sling 3 through the lifting lug 403. The lifting lug 403 and the hook shaft 401 are detachably connected, and the locking fit between the two is achieved through the locking pin, so that when the hook shaft 401 is severely worn after long-term use, only the hook shaft 401 can be replaced, which is low in cost and high in replacement efficiency. In addition, the locking pin between the hook shaft 401 and the lifting lug 403 is a second spring pin 404. The spring pin is provided here to maintain the reliable connection between the hook shaft 401 and the lifting lug 403 by utilizing the elastic force of the spring pin spring, and the spring pin can be automatically inserted into the pin hole provided in the lifting lug 403 and the hook shaft 401, which also has a high installation efficiency.

[0063] In this embodiment, the sling frame includes a frame body 1 and a limit connector 2 that is limit-connected to the frame body 1. The frame body 1 includes at least two connection positions for limiting connection with the limit connector 2, and is connected to the sling 3 through the limit connector 2, that is, the limit connector 2 has a sling installation position for installing the sling 3. In this way, the position of the sling point of the sling 3 can be changed by adjusting the connection position of the limit connector 2 and the frame body 1, so as to adapt to the lifting operation of battery boxes of different sizes and different centers of gravity.

[0064] like Figure 5 and Figure 6 As shown, in order to realize the limiting matching connection between the limiting connector 2 and the frame body 1, in this embodiment, the frame body 1 is provided with a plurality of limiting holes 101, the limiting holes 101 are arranged at intervals, the limiting connector 2 is matched with the limiting holes 101 through the limiting pins, and the limiting holes 101 form a connection position connected with the limiting connector 2. The limiting pins are connected with different limiting holes 101 to realize the change of the lifting point.

[0065] The limiting hole forms a stable limiting connection with the limiting connector 2 through the stop pin, so that after changing the position of the limiting connector 2, that is, changing the position of the hanging point, the position of the hanging point remains fixed. Compared with the prior art, this has higher safety.

[0066] It should be noted that the number of the limiting holes 101 is at least two, so that the switching of two lifting positions can be realized. However, according to actual needs, the number of the limiting holes 101 can be more than three, so that more lifting position switching can be realized. In addition, the number of limiting connectors 2 does not necessarily correspond to the number of slings 3. In this embodiment, each sling 3 is connected to the frame body 1 through a limiting connector 2, so that all slings 3 can change the lifting position. However, in other embodiments, one limiting connector can also be retained, that is, changing the lifting point position of one sling 3 can also achieve the change of the lifting point position, thereby adapting to the different centers of gravity of the battery box 5.

[0067] In this embodiment, the position-limiting connector 2 includes an upper connector 201, which is provided with a pin hole for connecting and cooperating with the position-limiting pin, and has a mating surface for connecting and cooperating with the upper surface of the frame body 1. The left and right sides of the upper connector 201 are connected with guide side plates 202, which are guided and matched with the frame body 1, and form a guide channel for the position-limiting connector 2 to move along the frame body 1 with the upper connector 201. This not only facilitates the position-limiting connector to move along the frame body, but also limits the position-limiting connector from swinging relative to the frame body.

[0068] Specifically, in this embodiment, the wire side plate 202 is an integrally bent "U"-shaped structure, whose opening is upwardly connected to the upper connecting member 201 by bolts, and at the same time, a sling installation position for connecting the sling 3 is formed at its bottom. This integrated structure facilitates the connection between the guide side plate 202 and the upper connecting member 201, and also has a high structural strength to ensure the stability of the lifting process. When connecting the sling 3, a bolt hole can be set at the bottom, and the sling 3 can be connected by connecting bolts 205. Of course, in order to achieve the connection between the sling 3 and the guide side plate 202, a hook or other structure can also be used.

[0069] Furthermore, in order to optimize the guiding and limiting effect of the limiting connector 2, in this embodiment, a guide bottom plate 203 is also provided on the inner wall of the relative guide side plate 202, thereby forming a closed guide hole. The limiting connector 2 is integrally mounted on the frame body 1, which has a full covering effect on the frame body 1, thereby enhancing the guiding effect and the limiting and fixing effect.

[0070] In this embodiment, the limit pin between the upper connecting member 201 and the frame body 1 is a first spring pin 204. Specifically, the upper connecting member 201 is a hollow rectangular tube, which can be directly cut from the steel section, has high strength, and its mass is not too large, which satisfies the lightweight requirement. Moreover, the hollow part forms an installation space for installing the first spring pin 204. After the position of the upper connecting member 201 is adjusted, the elastic force of the first spring pin 204 can automatically keep it locked with the frame body 1, which has good safety and high efficiency. Of course, in other embodiments, the ordinary pin shaft can also be inserted into the limit hole to achieve the limit matching of the limit connector 2 and the frame body 1. At this time, in order to prevent the pin shaft from falling off, the diameter of the pin shaft can be appropriately enlarged, or a stop structure that matches the stop of the limit hole can be set on the pin shaft.

[0071] Furthermore, in order to accurately observe the position of the limiting hole 101, in this embodiment, Figure 5As shown, the upper connector 201 is also provided with an observation channel 206, and the position of the observation channel 206 corresponds to the limiting hole 101. The position of the limiting hole 101 can be directly observed through the observation channel 206, so that the limiting pin can be accurately inserted into the limiting hole 101, thereby improving the installation efficiency. In addition, in this embodiment, the width of the observation channel 206 in the left and right directions is smaller than the width of the limiting hole 101, that is, the projection width of the observation channel 206 in the vertical direction is smaller than the projection width of the limiting hole 101 in the vertical direction, so that the area of ​​the observation channel 206 is smaller, and the upper connector 201 and the frame body 1 have a larger contact area, thereby ensuring the connection reliability between the upper connector 201 and the frame body 1. At the same time, in this embodiment, because the upper connector 201 is a rectangular tube, it has an opening, so it only needs to set a long groove on the bottom wall of the rectangular tube, and the long groove can be observed through the opening of the rectangular tube, thereby realizing the observation function, and at this time, except for the bottom wall, other parts are still intact, which can also effectively ensure the structural strength of the upper connector 201.

[0072] Of course, the observation channel is provided in this embodiment to facilitate the insertion of the limit pin into the limit hole and improve efficiency. In other embodiments, even if the observation channel is not provided, the staff can roughly judge the position of the limit hole according to the moving distance of the limit connector 2, and the limit pin can still be inserted into the limit hole.

[0073] The specific embodiment 2 of the sling provided by the present invention is different from the embodiment 1 mainly in that: in the embodiment 1, the limit connector of the sling frame includes an upper connector, and the upper connector is connected and matched with the upper surface of the frame body, so that the frame body can be used to provide stable support for the upper connector. In this embodiment, the upper connector may not be included. In order to realize the connection between the limit connector and the frame body, a limit hole may be opened in the side wall of the limit connector and the frame body, and a pin shaft is used to horizontally pass through the frame body and the limit connector. At this time, the pin shaft bears the downward pressure of the sling.

[0074] The specific embodiment 3 of the sling provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the connection position connected to the limit connector provided on the sling frame includes a limit hole, and the limit connector is connected to the frame body through a stop pin. In this embodiment, the connection position provided on the frame body can be a connection column fixed to the frame body, and in this case, a connection hole that cooperates with the connection column can be provided on the upper connection piece, and the position of the upper connection piece is adjusted to cooperate with the connection column plug-in limit.

[0075] The specific embodiment 4 of the sling provided by the present invention is different from the embodiment 1 mainly in that: in the embodiment 1, Figure 5As shown, the limiting hole of the sling frame extends in the up-down direction. In this embodiment, similar to Embodiment 2, the limiting hole can extend in the left-right direction, such as being opened on the guide side plate, so that the limiting connection between the limiting connector and the frame body can also be achieved.

[0076] The specific embodiment 5 of the sling provided by the present invention is different from the embodiment 1 mainly in that: in the embodiment 1, the upper connecting member of the sling frame is connected with a guide side plate. In this embodiment, the guide side plate may not be included, and the sling may be directly hung or tied to the upper connecting member.

[0077] The specific embodiment 6 of the sling provided by the present invention is different from the embodiment 1 mainly in that: in the embodiment 1, the guide side plate of the sling frame is an integrally formed structure. In this embodiment, the guide member connected to the upper connecting member can be two independent guide side plates, and the two guide side plates can be independently connected to the upper connecting member (welded or bolted). In addition, in order to achieve the guiding and limiting functions, the side guide member may not be a plate-like structure. In other embodiments, the side guide member may be a columnar or even a circular tubular structure.

[0078] The specific embodiment 7 of the sling provided by the present invention is different from the embodiment 1 mainly in that: in the embodiment 1, the upper connecting member of the sling frame is a rectangular tube. In this embodiment, the upper connecting member can be a connecting plate, and an observation channel can also be opened on the connecting plate.
