Description

Technical Field

[0001] The present application relates to the field of electric skid steer loaders, and in particular to a battery hoist and a battery hoisting system. Background Art

[0002] Electric skid-steer loaders are increasingly being used due to their ease of operation, maneuverability, compatibility with a wide range of attachments, and their ability to exponentially improve labor efficiency. They have become essential construction equipment for narrow work sites such as highways, basements, and municipal roads. The frame of an electric skid-steer loader is typically a welded four-sided structure with a compartment for the battery. During assembly, the battery is horizontally inserted into the frame through the rear door.

[0003] However, conventional lifting devices interfere with the top frame of the four-frame structure, forcing the batteries to be lifted to the edge of the rear door and then manually pushed horizontally in. Clearly, conventional lifting devices with manual assistance are inefficient, time-consuming, and labor-intensive, and pose safety risks such as battery damage during assembly. Utility Model Content

[0004] The purpose of this application is to provide a battery hoist and a battery hoisting system to solve the problems of low battery assembly efficiency and low safety during the assembly process.

[0005] To achieve the above-mentioned objectives, the present application provides a battery hoist on the one hand, which includes a hoist body, which includes an upper beam for lifting and a lower beam for lifting batteries and capable of extending into a skid loader. The rear ends of the upper beam and the lower beam are connected and a front end avoidance opening is formed between their front ends to avoid mechanical interference with the skid loader.

[0006] In some embodiments, the battery spreader further comprises:

[0007] The counterweight block is arranged at the front end of the upper crossbeam.

[0008] In some embodiments, the counterweight is slidably disposed along the length direction of the upper beam.

[0009] In some embodiments, the battery spreader further comprises:

[0010] The column is used to connect the rear end of the upper beam and the rear end of the lower beam.

[0011] In some embodiments, the battery spreader further comprises:

[0012] Handrails: Handrails are installed on the columns.

[0013] In some embodiments, the battery spreader further comprises:

[0014] A plurality of lifting components are arranged at intervals along the front-to-rear direction of the lower crossbeam;

[0015] Among them, the lifting assembly includes a transverse mounting rod and a hook assembly. The transverse mounting rod is arranged to pass through the lower crossbeam horizontally, and the two ends of the transverse mounting rod are respectively installed with hook assemblies.

[0016] In some embodiments, the hook assembly includes a hanging plate, a bow shackle, a double ring buckle, and a hanging ring connected in sequence;

[0017] Among them, the upper end of the hanging plate is pivotally connected to the horizontal mounting rod, the pin of the bow-shaped shackle is pivotally connected to the lower end of the hanging plate, one end of the double ring buckle is clamped with the bow-shaped shackle, and the other end is clamped with the upper end of the hanging ring, and the lower end of the hanging ring is connected to the suspended object.

[0018] In some embodiments, the battery spreader further comprises:

[0019] A plurality of lifting ears are arranged at intervals along the front-to-rear direction of the upper crossbeam;

[0020] Lifting chain, connected between the two lifting eyes.

[0021] In some embodiments, the battery spreader further comprises:

[0022] Long lifting ring, long lifting ring connected to the lifting chain.

[0027] Through the above technical solution, the battery hanger provided in the embodiment of the present application has the following beneficial effects:

[0028] In the technical solution of the present application, the upper crossbeam of the battery hoist is used for lifting, and the lower crossbeam is used for lifting the battery and loading the battery into the skid loader. Compared with the prior art, the battery is first lifted to the edge of the rear door of the skid loader frame by conventional hoists such as slings, and then manually pushed in horizontally. Since a front avoidance opening is formed between the upper crossbeam and the lower crossbeam, that is, an avoidance space extending backward from the front avoidance opening S is formed between the upper crossbeam and the lower crossbeam, when the battery hoist of the present application is lifting the battery, when the upper crossbeam moves above the frame, the avoidance space can be used to avoid interference between the battery hoist and the top frame of the frame, and the lower crossbeam can be extended into the frame of the skid loader, so that the battery can be directly assembled into the frame, reducing manual participation, thereby improving the assembly efficiency of the battery and the safety of the assembly process.

[0036] DETAILED DESCRIPTION

[0037] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0038] The battery hoist and battery hoisting system according to the present application are described below with reference to the accompanying drawings.

[0039] This application discloses a new type of battery sling, such as Figure 1 As shown, a battery hoist in a specific embodiment includes a hoist body 100, which includes an upper beam 110 for lifting and a lower beam 130 for lifting batteries and capable of extending into a skid loader. The rear ends of the upper beam 110 and the lower beam 130 are connected and a front end avoidance opening S is formed between their front ends to avoid mechanical interference with the skid loader.

[0040] Specifically, if Figure 1As shown, when assembling the battery of the skid loader by the battery hoist of the present application, the upper beam 110 can be moved above the frame of the skid loader. Since a front avoidance opening S is provided between the upper beam 110 and the lower beam 130 to avoid mechanical interference with the top frame of the skid loader, the lower beam 130 with the battery hoisted can be extended into the frame to hoist the battery into the frame. Compared with the prior art, the battery is first hoisted to the edge of the rear door of the skid loader frame by conventional hoists such as slings and then manually pushed in horizontally, the battery hoist of the present application can directly assemble the battery into the frame, and reduces manual participation, which can improve the battery assembly efficiency and the safety of the assembly process.

[0041] In this embodiment, if Figures 1 to 3 As shown, the battery spreader also includes:

[0042] The counterweight 200 is disposed at the front end of the upper beam 110 .

[0043] Specifically, if Figure 1 As shown, the front counterweight 200 installed on the upper crossbeam 110 can balance the overall center of gravity of the battery lift after the batteries are hoisted. As an example, the counterweight 200 can also be used to balance the handle set at the rear end of the battery lift. In this way, the introduction of the counterweight 200 helps to ensure that the center of gravity of the battery lift remains stable during use, thereby facilitating operation and further improving the safety of the assembly process.

[0044] In this embodiment, the counterweight 200 is slidably disposed along the length direction of the upper beam 110 .

[0045] like Figure 2 As shown, the counterweight 200 slidably arranged along the length direction of the upper crossbeam 110 can be adjusted in position so that the battery hoist can still ensure the stability of the overall center of gravity of the battery hoist when hoisting batteries of different specifications. As an example, when the battery needs to be installed at different positions on the lower crossbeam 130, the position of the counterweight 200 can also be adjusted to ensure the stability of the overall center of gravity of the battery hoist, thereby improving the maneuverability of the battery hoist under different battery hoisting methods. It will be understood by those skilled in the art that there are many ways to connect the counterweight 200 to the upper crossbeam 110, such as threaded connection between the counterweight 200 and the upper crossbeam 110, or selectively connecting the mounting holes set in position between the counterweight 200 and the upper crossbeam 110 through fixing pins.

[0046] In this embodiment, if Figure 2 As shown, the battery spreader also includes:

[0047] The column 120 is used to connect the rear end of the upper beam 110 and the rear end of the lower beam 130 .

[0048] Specifically, the crane body 100 is generally C-shaped, comprising an upper crossbeam 110, a column 120, and a lower crossbeam 130 connected in sequence. A clearance space extending rearward from a front clearance opening S is formed between the upper crossbeam 110 and the lower crossbeam 130. The upper crossbeam 110, the lower crossbeam 130, and the column 120 collectively form a clearance space to prevent mechanical interference with the skid steer loader. Furthermore, reinforcing plates 600 are provided at the junctions between the upper crossbeam 110, the lower crossbeam 130, and the column 120. This results in a simple structure, ease of processing, and overall structural strength. Of course, in other embodiments, the column 120 is not limited to the straight plate shape shown in the figure, but may also be curved or other shapes.

[0049] In this embodiment, if Figure 1 and Figure 2 As shown, the battery spreader also includes:

[0050] The armrest 500 is provided on the column 120 .

[0051] Specifically, the introduction of the handrail 500 facilitates the operator's control of the battery spreader. Positioning the handrail 500 in the middle of the column 120 facilitates its proximity to the spreader's center of gravity, thereby enhancing its maneuverability. Of course, the handrail 500 is not limited to the column 120 described above; it can also be positioned on the upper beam 110 or the lower beam 130.

[0052] In this embodiment, if Figures 1 to 4 As shown, the battery spreader also includes:

[0053] A plurality of hoisting assemblies 400 are arranged at intervals along the front-to-rear direction of the lower crossbeam 130;

[0054] The hoisting assembly 400 includes a transverse mounting rod 410 and a hook assembly 420 . The transverse mounting rod 410 is arranged to pass through the lower crossbeam 130 transversely, and the hook assemblies 420 are respectively installed at both ends of the transverse mounting rod 410 .

[0055] Specifically, if Figure 1 As shown, the battery hoisting load can be shared by multiple hoisting assemblies 400, and the stability of the battery hoisting can be ensured. The battery can be selectively connected to multiple hoisting assemblies 400, thereby improving the adaptability of the battery hoist to batteries of different specifications. Among them, the hook assemblies 420 are arranged symmetrically about the lower crossbeam 130, and the load of the hoisting assembly 400 can also be evenly shared by the hook assemblies 420, further improving the stability and reliability of the connection between the hoisting assembly 400 and the battery. Of course, the number of hoisting assemblies 400 is not limited to the two shown in the figure, and can also be other, or even only one.

[0056] In this embodiment, if Figure 3 and Figure 4 As shown, the hook assembly 420 includes a hanging plate 421, a bow-shaped shackle 422, a double ring buckle 423 and a hanging ring 424 connected in sequence;

[0057] Among them, the upper end of the hanging plate 421 is pivotally connected to the horizontal mounting rod 410, the pin 422a of the bow-shaped shackle 422 is pivotally connected to the lower end of the hanging plate 421, one end of the double ring buckle 423 is clamped with the bow-shaped shackle 422, and the other end is clamped with the upper end of the hanging ring 424, and the lower end of the hanging ring 424 is connected to the suspended object.

[0058] Specifically, the hook assembly 420 is pivotally connected to the transverse mounting rod 410 via the upper end of the hanger plate 421, allowing the hook assembly 420 to connect the transverse mounting rod 410 and the battery at various angles, thereby improving the compatibility between the battery and the battery hanger. After the latch 422a is pivotally connected to the lower end of the hanger plate 421, the bow-shaped shackle 422 can not only swing back and forth relative to the hanger plate 421, expanding the adaptability of the hook assembly 420 to batteries of different specifications, but also can be quickly disassembled and assembled with the hanger plate 421 via the latch 422a. One end of the double-ring buckle 423 is engaged with the bow-shaped shackle 422, and the other end is engaged with the upper end of the hanging ring 424, allowing the hanging ring 424 to swing left and right relative to the bow-shaped shackle 422, as well as forward and backward relative to the bow-shaped shackle 422. The pin of the double-ring buckle 423 can quickly realize the quick disassembly of the bow-shaped shackle 422 and the hanging ring 424. In this way, the load-bearing capacity of the hook assembly 420 is guaranteed on the basis of greatly expanding the adaptability of the hook assembly 420 to the battery, and the installation and disassembly is simple and the cost is low.

[0059] In this embodiment, the battery hanger further includes:

[0060] A plurality of lifting ears 300 , wherein the plurality of lifting ears 300 are arranged at intervals along the front-to-back direction of the upper crossbeam 110 ;

[0061] The lifting chain 700 is connected between the two lifting eyes 300 .

[0062] Specifically, see Figure 2 The battery lifter is connected to the hook via a lifting chain 700. This allows the battery lifter to swing relative to the hook, making it easier to operate. The lifting chain 700 can be selectively connected to any two of the multiple lifting lugs 300 to better match the battery lifter's center of gravity, improving its maneuverability and adaptability to batteries of varying sizes. Of course, the battery lifter is not limited to being connected to the hook via the aforementioned lifting chain 700; it can also be connected to the hook via a lifting belt or lifting rope.

[0063] In this embodiment, the battery hanger further includes:

[0064] Long lifting ring 800, long lifting ring 800 is connected with lifting chain 700.

[0065] Specifically, see Figure 2 The lower end of the long lifting ring 800 is connected to two lifting chains 700 arranged symmetrically relative to the long lifting ring 800 via two butterfly buckles. The upper end of the long lifting ring 800 is used to connect to the hook. This not only improves the stability of the connection between the hook and the lifting device, but also allows the long lifting ring 800 to swing relative to the hook, further improving the maneuverability of the battery lifting device.

[0066] The present application discloses a novel battery hoisting system. In a specific embodiment, the battery hoisting system includes:

[0067] The battery spreader mentioned above;

[0068] Driving, lifting the upper beam 110 by the crane hook;

[0069] The battery is hoisted on the lower crossbeam 130 .

[0070] Specifically, the battery includes a plurality of U-shaped hanging plates, and the side plates of the U-shaped hanging plates with downward openings are adjacent to the peripheral sides of the battery and are arranged close to the top surface of the battery. The lifting assembly 400 of the battery hoist is selectively engaged with the U-shaped hanging plates, and a variety of battery lifting methods relative to the battery hoist can also be realized. After the battery is fixed relative to the battery hoist, the position-adjustable crane hook moves the upper crossbeam 110 to the top of the frame of the skid loader by lifting the long lifting ring 800, and lifts the battery into the corresponding position in the frame through the lower crossbeam 130. Obviously, the battery lifting system also has all the technical effects of the above-mentioned battery hoist, so it will not be repeated here.
