Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a foam bucket transfer cart. Background Technology

[0002] Firefighting foam liquid is a special liquid used for fire extinguishing, mainly for extinguishing fires involving oil, flammable liquids, and some solids; foam liquid needs to be stored and transported using foam buckets.

[0003] In existing technology, foam buckets are transported by standing them upright on a flatbed trolley. However, the upright foam buckets have a high center of gravity, and the flatbed trolley is prone to tipping over when moving, resulting in poor stability and safety.

[0004] Therefore, it is necessary to provide a new type of foam bucket transport trolley. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the purpose of this utility model embodiment is to provide a foam bucket transfer trolley that can improve the stability and safety when transferring foam buckets.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foam bucket transfer trolley is provided, including a body, pulleys, casters, and claws. The body includes a main beam, a shovel plate, and legs connected to the main beam. The claws are disposed on the main beam. The shovel plate is located at the first end of the main beam, and the shovel plate and the claws are arranged opposite to each other, so that the shovel plate and the claws can clamp the upper and lower ends of the foam bucket, and the axis of the foam bucket is parallel to the length direction of the main beam. The pulleys are located at the first end of the main beam, and the casters are mounted on the legs. When the pulleys and casters are in contact with the ground, the legs can tilt and support the main beam on the ground.

[0007] Furthermore, the vehicle body also includes a crossbeam, which is vertically mounted on the first end of the main beam. Two oblique blocks are symmetrically arranged on the crossbeam and on both sides of the shovel plate, forming a V-shaped structure.

[0008] Furthermore, the vehicle body is equipped with two pulleys, which are spaced apart on the crossbeam.

[0009] Furthermore, the claw is slidably disposed on the main beam along the length direction of the main beam, and a screw is helically engaged on the claw, with the screw facing the outer peripheral wall of the main beam.

[0010] Furthermore, the outrigger is connected to the main beam via a connecting shaft. The outrigger can swing around the axis of the connecting shaft on the main beam. When the outrigger swings and drives the omnidirectional wheel away from the pulley, the outrigger is in an open state. At this time, when the pulley and the omnidirectional wheel are in contact with the ground, the outrigger can tilt and support the main beam on the ground. When the outrigger swings and drives the omnidirectional wheel closer to the pulley, until the two pulleys and the omnidirectional wheel are collinear, the outrigger is in a retracted state, and the outrigger is close to the main beam.

[0011] Furthermore, the connecting shaft is slidably mounted on the main beam along its length. A connecting arm is mounted on the support leg, and the connecting arm is provided with a connecting position one and a connecting position two spaced apart. The main beam is provided with a positioning structure one and a positioning structure two. When the support leg slides away from the pulley on the main beam via the connecting shaft and swings open, the connecting position one on the connecting arm locks with the positioning structure one on the main beam, thereby locking the support leg onto the main beam. When the support leg slides closer to the pulley on the main beam via the connecting shaft and swings close, the connecting position two on the connecting arm locks with the positioning structure two on the main beam, thereby locking the support leg onto the main beam.

[0012] Furthermore, the connecting arm is inclined relative to the outrigger. The connecting arm is slidably connected to the outrigger along the length of the outrigger via a connecting seat. Connecting position one and connecting position two are spaced apart on the connecting arm along the length of the connecting arm, with connecting position one being farther away from the outrigger than connecting position two. When the outrigger slides away from the pulley on the main beam via the connecting shaft and swings open, the connecting arm is slid away from the universal wheel until connecting position one on the connecting arm is aligned and locked with the positioning structure on the main beam. At this time, the connecting arm, outrigger, and main beam form a triangular stable structure. When the outrigger slides closer to the pulley on the main beam via the connecting shaft and swings closed, the connecting arm is slid closer to the universal wheel until connecting position two on the connecting arm is aligned and locked with the positioning structure two on the main beam. At this time, the connecting arm, outrigger, and main beam form a triangular stable structure.

[0013] Furthermore, the first connection position and the second connection position are positioning hole structures parallel to the connecting shaft, and the first positioning structure and the second positioning structure are pin structures parallel to the connecting shaft.

[0014] Furthermore, the main beam is provided with a mounting hole one corresponding to the positioning structure one, and the positioning structure one is telescopically disposed in the mounting hole one. The main beam is provided with a mounting hole two corresponding to the positioning structure two, and the positioning structure two is telescopically disposed in the mounting hole two.

[0015] Furthermore, a handle is provided at the second end of the main beam.

[0016] Compared with the prior art, the above-described technical solutions in this utility model embodiment have at least one of the following beneficial effects: This utility model provides a foam bucket transport trolley, including a body, pulleys, casters, and claws. The body includes a main beam, a shovel, and legs connected to the main beam. Claws are mounted on the main beam, and the shovel is located at the first end of the main beam, with the shovel and claws positioned opposite each other. This allows the shovel and claws to clamp the upper and lower ends of the foam bucket, aligning the axis of the foam bucket with the length of the main beam. The pulley is located at the first end of the main beam, and the casters are mounted on the legs. When the pulley and casters contact the ground, the legs tilt and support the main beam on the ground. This allows the foam bucket to be tilted and placed on the trolley body during transport, lowering the overall center of gravity. The shovel and claws further enhance the stability and safety of transporting the foam bucket. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0032] Example 1 Please refer to Figures 1 to 4 As shown, a foam bucket transfer trolley provided by this utility model will now be described. The foam bucket transfer trolley includes a body 1, pulleys 2, casters 3, and claws 4. The body 1 includes a main beam 11, a shovel plate 14, and support legs 15 connected to the main beam 11. The claws 4 are disposed on the main beam 11, and the shovel plate 14 is located at the first end of the main beam 11. The shovel plate 14 and the claws 4 are arranged opposite to each other, so that the shovel plate 14 and the claws 4 can clamp the upper and lower ends of the foam bucket 100, and make the axis of the foam bucket 100 aligned with the main beam 11. Along the length direction, pulley 2 is located at the first end of the main beam 11, and caster 3 is mounted on the support leg 15. When pulley 2 and caster 3 are in contact with the ground, the support leg 15 can tilt and support the main beam 11 on the ground. This allows the foam bucket transfer trolley provided in this embodiment to tilt the foam bucket 100 onto the vehicle body 1 when transferring the foam bucket 100, thereby lowering the overall center of gravity. The foam bucket 100 is clamped and fixed by the shovel plate 14 and the claw 4, which improves the stability and safety when transferring the foam bucket 100.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the vehicle body 1 also includes a crossbeam 12, which is vertically mounted on the first end of the main beam 11. Two inclined blocks 13 are symmetrically arranged on the crossbeam 12 and on both sides of the shovel plate 14. The two inclined blocks 13 form a V-shaped structure and are used to support the foam bucket 100 on both sides. The V-shaped structure formed by the two inclined blocks 13 is positioned with the foam bucket 100. Based on the principle of triangular stability, the rolling freedom of the foam bucket 100 along the radial plane is precisely restricted, preventing the foam bucket 100 from accidentally slipping off.

[0034] like Figure 2As shown, in some embodiments, the vehicle body 1 is provided with two pulleys 2, which are spaced apart on the crossbeam 12, so that the two pulleys 2 and the casters 3 form a stable support. At the same time, the two pulleys 2 provide unidirectional rolling, and the casters 3 provide steering and rolling functions. The independent steering characteristic of each caster 3 means that only a small force is required for steering, simplifying the operation process. Combined with the follow-up characteristics of the two directional pulleys 2, efficient path control is achieved, improving the mobility and ease of operation of the foam bucket transfer cart provided by this utility model embodiment.

[0035] like Figure 1 As shown, in some embodiments, the claw 4 is slidably disposed on the main beam 11 along the length direction of the main beam 11, so that the claw 4 can slide and adjust its position on the main beam 11 along the length direction of the main beam 11, thereby adjusting the distance between the shovel plate 14 and the claw 4 to adapt to foam buckets 100 of different heights; specifically, a screw 41 is screwed onto the claw 4, the screw 41 is facing the outer peripheral wall of the main beam 11, so that when the screw 41 is screwed onto the claw 4 and abuts against the side wall of the main beam 11, the claw 4 is locked onto the main beam 11, so that the shovel plate 14 and the claw 4 are clamped at the upper and lower ends of the foam bucket 100, and when the screw 41 is screwed onto the claw 4 and disengages from the main beam 11, the claw 4 can slide freely on the main beam 11.

[0036] like Figure 1 As shown, in some embodiments, a handle is provided at the second end of the main beam 11 to facilitate operation by the user holding the handle.

[0037] The foam bucket transfer trolley provided in this embodiment of the utility model has a main beam 11 that contacts the foam bucket 100 side by side, thereby evenly distributing the weight of the foam bucket 100, effectively avoiding local deformation, reducing stress concentration, and improving structural durability. At the same time, when the pulley 2 and the caster 3 are in contact with the ground, the support leg 15 tilts the main beam 11 to support it on the ground. The first end of the main beam 11 is located below the second end of the main beam 11, making the vehicle body 1 have a low center of gravity, which significantly reduces the overall center of gravity of the foam bucket transfer trolley when loading the foam bucket 100, preventing it from tipping over due to acceleration or turning, and enhancing the overall stability of the trolley under dynamic working conditions.

[0038] When using the foam bucket transfer trolley provided in Embodiment 2 of this utility model, such as Figure 3 As shown, hold the handle of the main beam 11 and position it perpendicular to the ground. Insert the shovel plate 14 at the end of the main beam 11 into the bottom of the foam bucket 100. Then move the claw 4 close to the foam bucket 100 and engage it at the top of the foam bucket 100. Next, hold the handle of the main beam 11 and rotate the second end of the main beam 11 around the pulley 2 and press it down (if the force is insufficient, you can simultaneously use your foot to step on the support leg 15 to limit the rolling of the pulley 2 relative to the ground). Figure 4As shown, once the casters 3 on the support leg 15 have landed and the center of gravity of the foam bucket 100 has been completely transferred to the vehicle body 1, the foam bucket transfer trolley can be moved.

[0039] Example 2 like Figures 5 to 8 As shown, the foam bucket transfer trolley provided in Embodiment 2 of this utility model differs from the foam bucket transfer trolley provided in Embodiment 1 in that: like Figure 5 As shown, in some embodiments, the outrigger 15 is connected to the main beam 11 via a connecting shaft 6, and the outrigger 15 can swing about the axis of the connecting shaft 6 on the main beam 11, such as... Figure 5 As shown, when the outrigger 15 swings and moves the caster 3 away from the pulley 2, the outrigger 15 is in an open state. At this time, when the pulley 2 and the caster 3 are in contact with the ground, the outrigger 15 can tilt and support the main beam 11 on the ground; as Figure 8 As shown, when the support leg 15 swings and drives the caster 3 to approach the pulley 2, until the two pulleys 2 and the caster 3 are collinear, the support leg 15 is in a retracted state, and the support leg 15 is close to the main beam 11. At this time, when the pulley 2 and the caster 3 are in contact with the ground, the support leg 15 no longer provides support to the main beam 11. On the one hand, when the support leg 15 is retracted, the structure of the foam bucket transfer cart is compact, which is convenient for storage and transportation. On the other hand, when the support leg 15 is retracted, when the foam bucket transfer cart is going up or down the steps, it is only necessary to control the pulley 2 and the caster 3 to pass over the steps at the same time, without having to control the pulley 2 and the caster 3 to go up or down the steps separately, making the operation more convenient.

[0040] like Figure 5 As shown, in some embodiments, the connecting shaft 6 is slidably mounted on the main beam 11 along its length. A connecting arm 7 is mounted on the support leg 15, and the connecting arm 7 is provided with a spaced-apart connecting position 73 and a second connecting position 74. The main beam 11 is provided with a positioning structure 16 and a second positioning structure 17. When the support leg 15 slides away from the pulley 2 on the main beam 11 via the connecting shaft 6, and the support leg 15 swings open, the connecting position 73 on the connecting arm 7 locks with the positioning structure 16 on the main beam 11, thereby locking the support leg 15 onto the main beam 11 and keeping the support leg 15 in the open state. Figure 8As shown, when the support leg 15 slides on the main beam 11 near the pulley 2 via the connecting shaft 6 and swings to retract, the connecting position 74 on the connecting arm 7 locks with the positioning structure 17 on the main beam 11, thereby locking the support leg 15 onto the main beam 11 and keeping the support leg 15 in a retracted state. The foam bucket transfer trolley provided in this embodiment of the utility model is slidably installed on the main beam 11 along the length direction of the main beam 11 via the connecting shaft 6, so that when the support leg 15 is opened, it needs to slide away from the pulley 2 on the main beam 11 via the connecting shaft 6, thereby increasing the span between the universal wheel 3 and the pulley 2, thus improving the overall stability when the universal wheel 3 and the pulley 2 are on the ground.

[0041] like Figure 6 As shown, in some embodiments, a guide groove 5 extending along the length of the main beam 11 is provided on the main beam 11, and the connecting shaft 6 is slidably inserted into the guide groove 5.

[0042] like Figure 7 and Figure 8 As shown, in some embodiments, the connecting arm 7 is inclined relative to the support leg 15. The connecting arm 7 is slidably connected to the support leg 15 along the length direction of the support leg 15 via the connecting seat 71. Connecting position one 73 and connecting position two 74 are spaced apart on the connecting arm 7 along the length direction of the connecting arm 7, and connecting position one 73 is farther away from the support leg 15 than connecting position two 74. When the support leg 15 slides away from the pulley 2 on the main beam 11 via the connecting shaft 6 and the support leg 15 swings open, the connecting arm 7 is slid away from the universal wheel 3 until the connecting position one 73 on the connecting arm 7 is connected to the main beam 11. Positioning structure 16 is aligned and locked. At this time, connecting arm 7, outrigger 15 and main beam 11 form a triangular stabilizing structure, thereby limiting the swing of outrigger 15 and the sliding of connecting shaft 6. When outrigger 15 slides on main beam 11 through connecting shaft 6 and approaches pulley 2, and outrigger 15 swings and retracts, connecting arm 7 is slid close to caster 3 until connecting position 74 on connecting arm 7 is aligned and locked with positioning structure 17 on main beam 11. At this time, connecting arm 7, outrigger 15 and main beam 11 form a triangular stabilizing structure, thereby limiting the swing of outrigger 15 and the sliding of connecting shaft 6.

[0043] like Figure 6 and Figure 7 As shown, in some embodiments, the connecting seat 71 is provided with a sliding groove 72, which slides and engages with the latching protrusion on the side of the support leg 15.

[0044] like Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, connection position one 73 and connection position two 74 are positioning hole structures parallel to the connecting shaft 6, and positioning structure one 16 and positioning structure two 17 are pin structures parallel to the connecting shaft 6, so that connection position one 73 and positioning structure one 16 are locked by plugging, and connection position two 74 and positioning structure two 17 are locked by plugging. Specifically, the main beam 11 is provided with mounting hole one 18 corresponding to positioning structure one 16, and positioning structure one 16 is telescopically disposed in mounting hole one 18. The main beam 11 is provided with mounting hole two 19 corresponding to positioning structure two 17, and positioning structure two 17 is telescopically disposed in mounting hole two 19.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
