Description

Technical Field

[0001] This utility model relates to the field of pad storage technology, specifically to pad storage devices and engineering machinery. Background Technology

[0002] During the use of construction machinery, in order to ensure the stability and safety of the operation, it is necessary to support the vehicle body with hydraulic outriggers. When the ground is soft or not flat enough, a pad needs to be placed between the ground and the outriggers.

[0003] The mats are usually placed in the mat rack that comes with the vehicle. The mat rack is a certain distance above the ground. Because the mats are large and heavy, multiple people are usually needed to lift them during transportation. This makes the process of picking up and retrieving the mats time-consuming and labor-intensive, which affects the operating efficiency of the construction machinery. Utility Model Content

[0004] In view of this, the present invention provides a pad storage device and engineering machinery to solve the problem of inconvenient pad retrieval and recycling.

[0005] In a first aspect, the present invention provides a pad storage device, including a storage rack and a ladder rack. The storage rack includes a storage chamber and an inlet / outlet communicating with the storage chamber. The inlet / outlet is located on the side of the storage rack. The ladder rack is located on the side where the inlet / outlet is located.

[0006] Beneficial effects: The pad storage device is suitable for use with rolling pads. The ladder can create a slope between the storage rack and the ground, allowing the pads to roll along the slope for easy access and recycling. The slope simplifies the process of moving the pads and reduces the difficulty of lifting them, thereby helping to reduce the manpower and time costs of handling and making it more convenient to access and recycle the pads. In addition, the ladder can be rotated to retract, avoiding obstruction of the passage of construction machinery.

[0007] In one alternative embodiment, the ladder frame includes a plurality of plates that are hinged together in sequence, and the ladder frame is switchable between an extended state and a retracted state.

[0008] Beneficial effects: By using a retractable ladder, the pad storage device can be adapted to use longer ladders, thereby extending the distance of the slope, reducing the slope gradient, and lowering the difficulty of lifting the pad.

[0009] In one optional embodiment, the ladder frame includes a first locking structure and a second locking structure, which are respectively disposed on adjacent plates. The first locking structure and the second locking structure can be connected to each other to lock the plates in the folded state.

[0010] Beneficial effects: By locking the plates when retracting, the ladder frame can be prevented from accidentally unfolding, thus improving the structural stability of the ladder frame during the operation of construction machinery.

[0011] In one alternative embodiment, the storage rack includes a third locking structure, and the ladder rack includes a fourth locking structure, the third locking structure and the fourth locking structure being able to connect to each other to secure the ladder rack when it is folded up.

[0012] Beneficial effects: By locking the ladder frame when it is retracted, the ladder frame can be prevented from being accidentally lowered, thus improving the structural stability of the ladder frame during the operation of construction machinery.

[0013] In one optional embodiment, the plate body includes a first plate body and a second plate body, one end of the first plate body is hinged to the storage rack, the other end of the first plate body is hinged to the second plate body, and the fourth locking structure is disposed on the second plate body. The fourth locking structure can be connected to or separated from the third locking structure by rotating the second plate body.

[0014] Beneficial effects: By setting the fourth locking structure in the second plate, the second plate can drive the fourth locking structure to connect to the third locking structure when it rotates, thereby simultaneously completing the folding of the ladder rack and locking the ladder rack relative to the storage rack, making the ladder rack more convenient to use.

[0015] In one optional embodiment, the third locking structure has a connecting hole, and the fourth locking structure includes a fastening part that can fasten with the connecting hole.

[0016] Beneficial effects: When the ladder frame is folded, the fastening part can be inserted into the connecting hole; when the ladder frame is unfolded, the fastening part can be disengaged from the connecting hole along the original path, realizing the connection or separation of the fourth locking structure and the third locking structure.

[0017] In one alternative embodiment, a first limiting member is further included, which is disposed on the storage rack and is capable of approaching or moving away from the rolling path of the pad, the first limiting member being used to limit the pad.

[0018] Beneficial effects: After the pad enters the storage chamber, the first limiting member blocks the rolling path of the pad, which can prevent the pad from rolling out of the storage chamber on its own, thus improving the safety of the pad storage device.

[0019] In one alternative embodiment, the storage rack includes a first connecting structure at the bottom, and the ladder includes a pivot at one end, the first connecting structure and the pivot being detachably connected.

[0020] Beneficial effects: The pivot and the first connecting structure are connected together, so that the ladder rack can rotate relative to the storage rack around the pivot. The pivot adopts a detachable connection method, which facilitates the replacement and maintenance of the ladder rack.

[0021] In one alternative embodiment, the first connecting structures are arranged in pairs, with the two first connecting structures in a pair spaced apart from each other in a third direction. A mounting groove for accommodating the rotating shaft is formed between the two first connecting structures. The pad storage device further includes a second limiting member, which is movably connected between the two first connecting structures to close or open the mounting groove.

[0022] Beneficial effects: The pivot is placed in the mounting slot, and the second limiting member closes the mounting slot, thereby limiting the pivot between the two first connecting structures and realizing the connection between the ladder rack and the storage rack. After the second limiting member opens the mounting slot, the pivot can be easily removed from the mounting slot, thereby simplifying the assembly and disassembly process of the ladder rack.

[0023] Secondly, this utility model also provides an engineering machinery, including a vehicle body and a pad storage device provided by this utility model, wherein the pad storage device is disposed on the vehicle body.

[0024] Beneficial effects: Engineering machinery includes the pad storage device provided by this utility model, and therefore has the corresponding beneficial effects brought by the pad storage device, which will not be elaborated here. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0035] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this utility model, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] In related technologies, the pad 9 is placed inside a pad storage device for transport with the vehicle, allowing for easy access and providing a flat support surface for the outriggers of the construction machinery, while reducing the pressure exerted by the machinery on the ground. To ensure the passability of the construction machinery, the pad storage device needs to be raised a certain distance above the ground. For large construction machinery, the size and weight of the pad 9 are also relatively large. When returning it, multiple operators need to lift the pad 9 together, or it needs to be lifted by hoisting, which is not only time-consuming and labor-intensive, but also poses safety issues.

[0038] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0039] Reference Figure 1 , Figure 2According to an embodiment of the present invention, a pad storage device is provided, including a storage rack 1 and a ladder rack 2. The storage rack 1 includes a storage chamber and an inlet / outlet 101 communicating with the storage chamber. The inlet / outlet 101 is located on the side of the storage rack 1. The ladder rack 2 is located on the side where the inlet / outlet 101 is located. One end is rotatably connected to the bottom of the storage rack 1, and the other end can rotate to contact the ground to form a slope for the pad 9 to roll into the storage chamber.

[0040] On the one hand, the pad storage device is suitable for use with the rolling pad 9. The ladder 2 can create a slope between the inlet / outlet 101 and the ground. The pad 9 can roll along the slope to realize the use and recycling. The slope can simplify the process of transporting the pad 9 and reduce the difficulty of lifting the pad 9. Ideally, only one operator is needed to complete the use and recycling of the pad 9, which helps to reduce the manpower and time costs of transportation and makes the use and recycling of the pad 9 more convenient.

[0041] On the other hand, during use, the ladder frame 2 contacts the ground by rotating, and after use, the ladder frame 2 can be retracted by rotating to avoid affecting the passage of engineering machinery.

[0042] It should be pointed out that, Figure 1 , Figure 2 The pad 9 shown is only for illustrative purposes to illustrate the working principle of the pad storage device. Figure 1 and Figure 2 In the illustrated embodiment, the rollable pad 9 includes a circular main structure and a detachable handle. An operator can first lift the pad 9, which is lying flat on the ground, using the handle, then detach the handle and push the main structure to roll into the storage compartment. In other embodiments not shown, the rollable pad 9 can also adopt other designs, as long as it can roll along the slope into and out of the storage compartment; this invention does not impose any limitations on this. For example, the pad 9 can also include a square main structure and rollers disposed on the side of the main structure. After the pad 9 is lifted, the rollers contact the ground, thereby enabling it to roll.

[0043] Optionally, in some embodiments, after rolling into the storage chamber, the pad 9 remains upright (thickness direction along the horizontal direction) and is stored in the storage chamber, thereby making fuller use of the space in the third direction (shown in the Z direction in the figure), which helps to reduce the space occupied by the pad storage device in the horizontal direction, thus facilitating the side-by-side placement of multiple pads 9 and reducing the impact of the pad storage device on the passage capacity of engineering machinery.

[0044] For example, refer to Figure 1 and Figure 2In some embodiments, the inlet and outlet 101 of the pad storage device faces a first direction (shown in the X direction in the figure). There are two inlets and outlets 101, located on both sides of the pad storage device. The four pads 9 are divided into two groups and enter the storage chamber from the inlets and outlets 101 on both sides. The ladder 2 also includes a guide rail 103 and a base plate. The guide rail 103 is disposed on the base plate and extends in the first direction, thereby forming two guide grooves at the bottom of the ladder 2 that match the thickness of the pads 9. The pads 9 can be pushed into the storage chamber under the guidance of the guide grooves. The two pads 9 pushed in from the same inlet and outlet 101 are located in the two guide grooves respectively, so that they are placed side by side with a certain interval to avoid being hindered by the friction of adjacent pads 9 when taking out the pads 9.

[0045] Understandably, the number of storage units in pad 9 can be flexibly adjusted according to the needs of construction machinery, and is not limited to... Figure 1 and Figure 2 The four pads 9 shown in the embodiment can also be positioned in the storage room by means other than the guide rail 103, as long as the pads 9 can be stably placed side by side. This utility model does not limit this.

[0046] Optionally, in some embodiments, the ladder 2 can switch between an extended state and a retracted state.

[0047] By employing a retractable ladder 2, the pad storage device is suitable for using a longer ladder 2. When retracted, the ladder 2 is in a retracted state, thereby reducing the length of the ladder 2 and minimizing the negative impact on the passage performance of engineering vehicles. When in use, the ladder 2 switches to an extended state, thereby extending the distance of the slope, reducing the slope gradient, reducing the load on the operator when pushing the pad 9, and reducing the difficulty of lifting the pad 9.

[0048] Optionally, in some embodiments, the ladder frame 2 includes a plurality of plates that are hinged together in sequence, so that the ladder frame 2 can switch between an unfolded state and a retracted state by folding. When retracted, the plates are stacked side by side to reduce the overall size of the ladder frame 2.

[0049] For example, refer to Figure 1 , Figure 2 and Figure 3 There are two plates, including a first plate 204 and a second plate 205. One end of the first plate 204 is hinged to the storage rack 1, so that it can rotate relative to the storage rack 1. The other end of the first plate 204 is hinged to the second plate 205. The second plate 205 is used to contact the ground.

[0050] It is understood that the ladder frame 2 can be provided with more panels, and the ladder frame 2 is not limited to switching states by folding; this utility model does not impose any limitations on this. For example, in some embodiments not shown, the ladder frame 2 can also switch between an extended state and a retracted state by telescopic means. In this case, the first panel 204 can be hinged to the storage rack 1, and the second panel 205 can be mounted on the first panel 204 via a slide rail, thereby extending or retracting relative to the first panel 204.

[0051] Optionally, in some embodiments, the ladder frame 2 includes a first locking structure 201 and a second locking structure 202, which are respectively disposed on adjacent plates. The first locking structure 201 and the second locking structure 202 can be connected to each other to lock the plates in the retracted state. By locking the plates when retracted, the ladder frame 2 can be prevented from accidentally unfolding, thus improving the structural stability of the ladder frame 2 during the operation of the construction machinery.

[0052] Depending on the specific switching method used in the ladder frame 2, the first locking structure 201 and the second locking structure 202 can adopt different designs and achieve mutual connection in different ways. For example, refer to... Figure 1 , Figure 2 and Figure 4 The first locking structure 201 is a hook, which is hinged to both sides of the first plate 204 along the second direction (shown in the Y direction in the figure). The second locking structure 202 is a pin, which is set on both sides of the second plate 205 along the second direction. In the retracted state, the second plate 205 flips and approaches the first plate 204. At this time, the hook can rotate and hang on the pin, so that the first locking structure 201 and the second locking structure 202 are engaged with each other and the plate is locked.

[0053] In addition to the snap-fit ​​connection, the first locking structure 201 and the second locking structure 202 can also be connected to each other by magnetic attraction or other means. The relevant design can be referred to the existing technology, and will not be described in detail here.

[0054] Optionally, in some embodiments, the storage rack 1 includes a third locking structure 102, and the ladder rack 2 includes a fourth locking structure 203. The third locking structure 102 and the fourth locking structure 203 can be connected to each other to fix the ladder rack 2 when it is retracted. By locking the ladder rack 2 when it is retracted, the ladder rack 2 can be prevented from being accidentally lowered, thereby improving the structural stability of the ladder rack 2 during the operation of the construction machinery.

[0055] To simplify the operation steps when using the ladder 2, in some embodiments, refer to Figure 3 and Figure 4The fourth locking structure 203 is disposed on the second plate 205. The fourth locking structure 203 can be connected to or separated from the third locking structure 102 by rotating the second plate 205. By disposing of the fourth locking structure 203 on the second plate 205, the rotation of the second plate 205 can drive the fourth locking structure 203 to connect to the third locking structure 102, thereby simultaneously completing the folding of the ladder rack 2 and locking the ladder rack 2 relative to the storage rack 1, making the use of the ladder rack 2 more convenient.

[0056] Specifically, when retracting the ladder rack 2, the first plate 204 is first flipped upwards and rotated to a position close to the inlet / outlet 101. During this process, the second plate 205 naturally flips downwards under the influence of gravity, thus achieving the initial folding of the ladder rack 2. When the first plate 204 is rotated into position, the second plate 205 is adjusted so that the fourth locking structure 203 on the second plate 205 connects to the third locking structure 102, thereby locking the ladder rack 2 relative to the storage rack 1. Then, the first locking structure 201 and the second locking structure 202 are interlocked to lock the plate, thus completing the folding of the ladder rack 2. When the ladder rack 2 is needed, the first locking structure 201 and the second locking structure 202 are first separated from each other. Then, the second plate 205 is flipped, causing the second plate 205 to separate the fourth locking structure 203 and the third locking structure 102, thus simultaneously unfolding the ladder rack 2 and releasing it relative to the storage rack 1.

[0057] For example, the third locking structure 102 has a connecting hole, and the fourth locking structure 203 includes a fastening part that can fasten with the connecting hole. When the ladder frame 2 is folded, the fastening part can be inserted into the connecting hole; when the ladder frame 2 is unfolded, the fastening part can be disengaged from the connecting hole, thus connecting or separating the fourth locking structure 203 and the third locking structure 102. Besides the fastening connection, the third locking structure 102 and the fourth locking structure 203 can also be connected to each other by magnetic attraction or other means. Related designs can be found in existing technologies and will not be elaborated here.

[0058] In some embodiments, the plate has perforations. The perforations can reduce the weight of the plate, making it lighter and easier to handle, and also contribute to the lightweight design of the pad storage device.

[0059] In some embodiments, the pad storage device further includes a first limiting member 3, which is disposed on the storage rack 1 and is capable of approaching or moving away from the rolling path of the pad 9. The first limiting member 3 is used to limit the pad 9. For example, see... Figure 4 The first limiting component 3 is a first pin, which is detachably inserted into the storage rack 1. The first pin can block the inlet and outlet 101, thereby achieving a limiting effect.

[0060] It should be noted that when the ladder rack 2 is retracted, the ladder rack 2 also blocks the entrance and exit 101, which can also play a limiting role. The ladder rack 2 and the first limiting component 3 can play a double insurance role to ensure that the pad 9 is safely and reliably stored in the storage rack 1.

[0061] In some embodiments, the storage rack 1 includes a first connecting structure 104 located at the bottom, and the ladder rack 2 includes a pivot 206 located at one end. The first connecting structure 104 and the pivot 206 are detachably connected. The pivot 206 and the first connecting structure 104 are connected together, thereby enabling the ladder rack 2 to rotate relative to the storage rack 1 about the pivot 206. The pivot 206 is detachably connected, which facilitates the replacement and maintenance of the ladder rack 2.

[0062] For example, refer to Figure 5 In some embodiments, the first connecting structures 104 are arranged in pairs, with the two pairs of first connecting structures 104 spaced apart from each other in the third direction. An installation groove for accommodating the rotating shaft 206 is formed between the two first connecting structures 104. The pad storage device also includes a second limiting member 4, which is movably connected between the two first connecting structures 104 to close or open the installation groove.

[0063] The mounting slot has an opening in the first direction. The rotating shaft 206 is placed in the mounting slot through the opening. The second limiting member 4 blocks the opening, thereby closing the mounting slot and limiting the rotating shaft 206 between the two first connecting structures 104, realizing the connection between the ladder rack 2 and the storage rack 1. After the second limiting member 4 is removed from the opening, the mounting slot opens, and the rotating shaft 206 can be easily removed from the mounting slot, thereby simplifying the disassembly and assembly process of the ladder rack 2.

[0064] Specifically, in some embodiments, the first connecting structure 104 can be a first connecting lug, and the second limiting member 4 can be a limiting screw. The limiting screw passes through the two first connecting lugs and is locked by a nut, thereby closing the mounting groove. The mounting groove can be easily opened by pulling out the limiting screw.

[0065] Of course, besides Figure 5 In addition to the embodiments shown, the rotating shaft 206 can also be detachably connected to the first connecting structure 104 in other ways, such as using a detachable clamp or shaft seat as the first connecting structure 104, etc. The present invention does not limit this.

[0066] In some embodiments, the storage rack 1 further includes a second connecting structure 105 for connecting to the vehicle body. The pad storage device is connected to the vehicle body via the second connecting structure 105, thereby enabling it to move with the vehicle and meet the need for readily accessible pad 9.

[0067] For example, refer to Figure 1 and Figure 3 The second connecting structure 105 is a fixing seat, which is connected to the vehicle body by fasteners (such as screws), thereby stably fixing the pad storage device to the vehicle body.

[0068] To further facilitate the installation of the pad storage device, in some embodiments, the storage rack 1 also includes a third connecting structure 106, which is a second connecting ear. The third connecting structure 106 is located above the second connecting structure 105, and the third connecting structure 106 can be connected to the vehicle body through a second pin (not shown in the figure).

[0069] During installation, the third connecting structure 106 is first connected to the vehicle body, so that the pad storage device is hung on the vehicle body, and the second connecting structure 105 is accurately aligned with the vehicle body, avoiding the situation where the second connecting structure 105 is difficult to align.

[0070] Secondly, this utility model also provides an engineering machinery, including a vehicle body and a pad storage device provided by this utility model, wherein the pad storage device is installed on the vehicle body.

[0071] Construction machinery includes the pad storage device provided by this utility model, and therefore has the beneficial effects brought by the pad storage device, which will not be elaborated here. Construction machinery can specifically be cranes, mixer trucks, and other types of construction machinery that require pads 9, and this utility model does not limit this.

[0072] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
