Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery parts technology, specifically to a toolbox and engineering machinery. Background Technology
[0002] As a type of non-road mobile machinery, excavators generally use urea solution to reduce nitrogen oxides in the engine exhaust in order to meet the National IV and Stage V emission standards. This makes urea solution a daily consumable for excavator operation.
[0003] Excavators typically have only one urea tank, which needs to be replenished with urea solution every shift (usually 16-20 hours). To ensure the reliability of the urea piping system, the length of the urea hose is limited. Generally, the urea tank is placed inside the excavator's toolbox. However, this placement takes up valuable internal space in the toolbox, making storage space for both the tank and tools relatively small, which is inconvenient for storing frequently used tools. Furthermore, the toolbox usually only has one door, and both adding urea solution to the tank and retrieving tools from the toolbox are done by opening this single door. Adding urea solution requires manually lifting the tank, which is not only laborious but also prone to spilling urea solution onto the tools, causing contamination and significantly increasing tool maintenance costs.

[0030] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0031] Please see Figures 1 to 3 This application provides a toolbox, including: a box body 1, the box body 1 being divided into a first chamber 11 for placing tools and a second chamber 12 for placing urea tanks, the top of the corresponding first chamber 11 of the box body 1 being provided with a first box cover 13 for supporting urea tanks and being openable, and the top of the corresponding second chamber 12 of the box body 1 being provided with a second box cover 14 that can be opened.
[0032] The housing 1 is made of high-strength metal materials, such as aluminum alloy or stainless steel, so that the first cover 13 can support the urea tank. The housing 1 is equipped with a partition to divide it into a first chamber 11 and a second chamber 12. The first cover 13 can be used to open or close the first chamber 11 by pushing or rotating, and the second cover 14 can be used to open or close the second chamber 12 by pushing or rotating.
[0033] Based on this, the toolbox has a first chamber 11 and a second chamber 12 to separate the tools and the urea tank, preventing spillage of urea solution onto the tools when adding it to the tank, thus reducing tool maintenance costs. Furthermore, a first cover 13 is located on the top of the corresponding first chamber 11 of the box body 1, and a second cover 14 is located on the top of the corresponding second chamber 12 of the box body 1. In conjunction with the toolbox's mounting position on the turntable, opening the first cover 13 facilitates easy access to tools, while opening the second cover 14 facilitates easy addition of urea solution to the tank. Simultaneously, when adding urea solution, the urea container can be placed on the first cover 13, eliminating the need for prolonged and strenuous manual lifting, thus saving effort. Therefore, this toolbox, when installed on construction machinery, offers convenient tool access, effortless urea solution addition, and prevents urea solution contamination of tools, significantly reducing tool maintenance costs and difficulty, and increasing customer satisfaction.
[0034] Specifically, the first cover 13 is rotatably mounted on the top of the corresponding first chamber 11 of the box body 1, and / or the second cover 14 is rotatably mounted on the top of the corresponding second chamber 12 of the box body 1.
[0035] Both the first lid 13 and the second lid 14 can be mounted on the top of the container 1 using a rotatable structure such as a hinge 2. To access tools, the first lid 13 is opened by rotating it; after access, it is closed by rotating it. To add urea solution to the urea tank, the second lid 14 is opened by rotating it, the urea container is placed on the first lid 13, and urea solution is added. After adding the urea solution, the second lid 14 is closed by rotating it.
[0036] A first support member 15 is provided between the top of the first cover 13 and the top of the corresponding first chamber 11 of the box body 1, and / or a second support member 16 is provided between the top of the second cover 14 and the top of the corresponding second chamber 12 of the box body 1.
[0037] Both the first support member 15 and the second support member 16 are rod-shaped structures. When the first cover 13 is closed on the top of the corresponding first chamber 11 of the box body 1, the first support member 15 is retracted into the first chamber 11. When the first cover 13 is rotated to open the first chamber 11, the first support member 15 supports the first cover 13 to prevent it from being accidentally closed. When the second cover 14 is closed on the top of the corresponding second chamber 12 of the box body 1, the second support member 16 is retracted into the second chamber 12. When the second cover 14 is rotated to open the second chamber 12, the second support member 16 supports the second cover 14 to prevent it from being accidentally closed, thus ensuring smooth addition of urea solution.
[0038] In one or more embodiments, a buffer structure 7 is provided between the first lid 13 and / or the second lid 14 and the box body 1. The buffer structure 7 may be provided only between the first lid 13 and the box body 1, or only between the second lid 14 and the box body 1. Alternatively, the buffer structure 7 may be provided between both the first lid 13 and the box body 1, and between the second lid 14 and the box body 1, to achieve a buffering effect and prevent noise and damage when the first lid 13 and / or the second lid 14 are closed on the box body 1. The buffer structure 7 may be a buffer strip, rubber block, rubber pad, or similar structure provided on the top of the first chamber 11 and / or the second chamber 12 of the box body 1.
[0039] See Figure 2-4 The first lid 13 is connected to one side of the box body 1 by a first locking member 5, and a notch 17 is provided at the connection point between the box body 1 and the first lid 13. The first locking member 5 can be a snap-fit structure, a latch structure, etc., to lock the first lid 13 when it is closed on the top of the box body 1, ensuring the closure of the first chamber 11. When it is necessary to open the first chamber 11, the first locking member 5 can be opened to allow the first lid 13 to rotate and open.
[0040] The notch 17 is located at the top of the first chamber 11 of the housing 1, and is provided on one side of the first locking member 5. The notch 17 is recessed towards the first chamber 11 relative to the first cover 13 to form a handle-like structure, so that when the first locking member 5 is unlocked, the first cover 13 can be lifted up and rotated by means of the notch 17.
[0041] See Figure 1 , Figure 2 and Figure 5 The second cover 14 is connected to the box body 1 by a second locking member 6. The second locking member 6 is provided on the second cover 14 and has a recessed portion 61. The second locking member 6 has a structure similar to a panel lock, which is directly provided on the second cover 14 and locks to the box wall of the corresponding second chamber 12 of the box body 1.
[0042] Since the first cover 13 and the second cover 14 are arranged adjacent to each other, and the second locking member 6 is directly disposed on the second cover 14, a recessed portion 61 is provided in the second locking member 6 facing the second chamber 12 to facilitate opening and rotating the second cover 14 when the second locking member 6 is unlocked. Thus, when it is necessary to add urea solution into the urea tank, the second locking member 6 is unlocked, and the second cover 14 is lifted and rotated by means of the handle-like structure of the recessed portion 61, thereby opening the second chamber 12.
[0043] In one or more embodiments, a recess 61 is provided at one end of the second locking member 6, and a protrusion 62 is provided on the periphery of the second locking member 6. The protrusion 62 is inclined downward from the recess 61 along its setting direction. The protrusion 62 can improve the structural strength of the second box cover 14 on the one hand, and facilitate the drainage of water out of the toolbox in the event of rain or other situations, following the slope of the protrusion 62 and the box body 1, thus preventing a large amount of water from accumulating in the second locking member 6, especially the recess 61, and ensuring the effectiveness of the lock and handle.
[0044] See Figure 1 The toolbox 1 has a foot pedal 18 on its side. The toolbox is typically installed on the turntable of construction machinery. The foot pedal 18 can be located on any side of the toolbox 1, preferably on a side convenient for personnel to pass through, allowing personnel to move up and down the turntable using the foot pedal 18 and the toolbox. The foot pedal 18 can be an integral part of the toolbox 1, or it can be fixed to the toolbox 1 using bolts or other connecting components.
[0045] The top surface of the first cover 13 and / or the second cover 14 is provided with an anti-slip structure 3, and the first cover 13 and / or the second cover 14 are provided with reinforcing ribs 4. The anti-slip structure 3 can be provided only on the first cover 13, only on the second cover 14, or both on both the first and second covers 14. The anti-slip structure 3 can be an upwardly protruding structure of any shape, and multiple such structures can be provided at intervals to achieve the purpose of anti-slip. The reinforcing rib 4 can be provided only on the first cover 13, only on the second cover 14, or both on both the first and second covers 14. The reinforcing rib 4 is at least one rib structure to improve the structural strength of the first cover 13 and / or the second cover 14. When the reinforcing rib 4 is provided on the first cover 13, it can improve the structural strength of the first cover 13, thereby increasing its capacity to support the urea tank. When the anti-slip structure 3 and the reinforcing rib 4 are both provided on the first box cover 13 and the second box cover 14, it is convenient to improve the structural strength and anti-slip function of the first box cover 13 and the second box cover 14, thereby improving the safety of personnel stepping on the toolbox to pass through.
[0046] In addition, this application embodiment also provides an engineering machine, including: a turntable and the above-mentioned toolbox, the toolbox being mounted on the turntable.
[0047] Construction machinery such as excavators and material handling machines have a space on their turntable for installing toolboxes. The toolboxes can be installed on the turntable with bolts or other connectors, which facilitates the storage and retrieval of tools, the addition of urea solution, and provides convenience for personnel to move up and down.
[0048] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
