[0001] The present invention relates to the technical field of aerial work equipment, and in particular to an underframe and an aerial work platform having the underframe. Background Art

[0002] In the field of aerial work equipment technology, scissor-type aerial work platforms are currently the most widely used type of aerial work equipment. The chassis of traditional scissor-type aerial work platforms all place leg supports on the reinforcement ribs welded to the chassis body. The chassis body and legs connected in this way have a safety hazard of being unstable when the aerial work platform is lifted. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a chassis that can improve the stability of an aerial work platform during lifting.

[0004] The present invention also provides an aerial work platform having the above-mentioned base frame.

[0005] According to an embodiment of the first aspect of the present invention, a base frame includes a base frame body, the base frame body has a connecting plate and a support plate connected to the connecting plate, the connecting plate and the support plate are arranged at an angle, and the support plate is located on one side of the connecting plate; a leg assembly, the leg assembly is connected to the base frame body, the leg assembly includes a leg support and a leg body connected to the leg support, the leg support is connected to a side of the connecting plate away from the support plate, and the leg body can move up and down relative to the base frame body; and a reinforcement assembly, the reinforcement assembly is connected to the base frame body, the reinforcement assembly includes a first reinforcement member, the first reinforcement member is connected to a side of the connecting plate close to the support plate, and the first reinforcement member is also connected to the support plate, and the first reinforcement member is arranged back to back to the leg support.

[0006] The chassis according to the embodiment of the present invention has at least the following technical effects:

[0007] In the above-mentioned chassis, when the aerial work platform is lifted, in order to ensure the stability of the aerial work platform, it is necessary to add a leg assembly to the chassis body to enhance the stability of the chassis body, thereby ensuring the stability of the aerial work platform. Since the base frame body has a connecting plate and a support plate connected to one side of the connecting plate, the leg support is connected to the side of the connecting plate away from the support plate, and the leg body is connected to the leg support, the leg assembly can be directly connected to the base frame body. The leg assembly directly connected to the base frame body can have better connection stability than the leg assembly connected to the external component of the base frame body. The external component connected to the base frame body increases the torque of the leg assembly when the leg assembly is operating, which easily causes the leg to be subjected to greater local stress, resulting in an unstable connection between the leg assembly and the base frame body, and even easily causing the leg assembly to fall off from the base frame body. The leg assembly directly connected to the base frame body will greatly reduce the torque of the leg assembly, thereby reducing the local stress on the leg assembly, and can make the leg assembly and the base frame body have stronger connection stability, further ensuring that the base frame body and the aerial work platform have better operating stability.

[0008] In addition, because the connecting plate and the support plate are arranged at an angle, the first reinforcement member of the reinforcement assembly is connected to the side of the connecting plate closest to the support plate, and the first reinforcement member is also connected to the support plate. Therefore, the reinforcement assembly strengthens the connection stability between the connecting plate and the support plate. Moreover, because the first reinforcement member is arranged opposite to the leg support, the reinforcement assembly not only strengthens the connection stability between the connecting plate and the support plate, but also further strengthens the connection stability between the leg assembly and the chassis body. This further ensures that the chassis body and the aerial work platform have better operating stability.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] like Figure 1 As shown, a chassis according to an embodiment includes a chassis body 100 , a leg assembly 200 and a reinforcement assembly 300 .

[0040] Specifically, the base frame body 100 has a connecting plate and a support plate connected to the connecting plate, the connecting plate and the support plate are set at an angle, and the support plate is located on one side of the connecting plate; the leg assembly 200 is connected to the base frame body 100, the leg assembly 200 includes a leg support 210 and a leg body 220 connected to the leg support 210, the leg support 210 is connected to the side of the connecting plate away from the support plate, and the leg body 220 can move up and down relative to the base frame body 100; the reinforcement assembly 300 is connected to the base frame body 100, the reinforcement assembly 300 includes a first reinforcement 310, the first reinforcement 310 is connected to a side of the connecting plate close to the support plate, the first reinforcement 310 is also connected to the support plate, and the first reinforcement 310 is set back to the leg support 210.

[0041] More specifically, the reinforcement assembly 300 is provided at the connection between the connecting plate and the supporting plate.

[0042] In the above-mentioned chassis, when the aerial work platform is lifted, in order to ensure the stability of the aerial work platform, it is necessary to add a leg assembly 200 to the chassis body 100 to enhance the stability of the chassis body 100, thereby ensuring the stability of the aerial work platform. Since the chassis body 100 has a connecting plate and a support plate connected to one side of the connecting plate, the leg support 210 is connected to the side of the connecting plate away from the support plate, and the leg body 220 is connected to the leg support 210, the leg assembly 200 can be directly connected to the chassis body 100. The leg assembly 200 directly connected to the chassis body 100 has better connection stability than the leg assembly 200 connected to the external component of the chassis body 100. The external component connected to the chassis body 100 increases the leg assembly 200 when the leg assembly 200 is working. 00, which may easily cause the support legs to be subjected to greater local stress, resulting in an unstable connection between the support leg assembly 200 and the base frame body 100, and even the support leg assembly 200 and the base frame body 100 may fall off. The support leg assembly 200 directly connected to the base frame body 100 will greatly reduce the torque of the support leg assembly 200, thereby reducing the local stress on the support leg assembly 200, and enabling the support leg assembly 200 and the base frame body 100 to have a stronger connection stability, further ensuring that the base frame body 100 and the aerial work platform have better operating stability.

[0043] In addition, because the connecting plate and the support plate are arranged at an angle, the first reinforcement member 310 of the reinforcement assembly 300 is connected to the side of the connecting plate closest to the support plate, and the first reinforcement member 310 is also connected to the support plate. Therefore, the reinforcement assembly 300 strengthens the connection stability between the connecting plate and the support plate. Moreover, because the first reinforcement member 310 is arranged opposite to the leg support 210, the reinforcement assembly 300 not only strengthens the connection stability between the connecting plate and the support plate, but also further strengthens the connection stability between the leg assembly 200 and the chassis body 100. This further ensures that the chassis body 100 and the aerial work platform have better operating stability.

[0044] Specifically, the leg support 210 is fixedly connected to the connecting plate. In some embodiments, the leg support 210 is welded to the connecting plate.

[0045] Furthermore, the connecting plate is fixedly connected to the supporting plate. In some embodiments, the connecting plate is welded to the supporting plate.

[0046] like Figure 1 、 Figure 2 as well as Figure 4As shown, in one embodiment, the leg body 220 includes a telescopic driving member 221, the telescopic driving member 221 has a sleeve 2211 and a telescopic portion 2212 inserted into the sleeve 2211, the bottom of the sleeve 2211 is detachably fixedly connected to the leg support 210, and the telescopic portion 2212 can move up and down relative to the leg support 210 and the sleeve 2211.

[0047] Specifically, in one embodiment, the leg support 210 has a U-shaped plate 211 with an opening downward and a mounting portion 212, one of the U-shaped surfaces of the U-shaped plate 211 is welded to the connecting plate, and the top of the U-shaped surface of the U-shaped plate 211 away from the connecting plate is provided with a first mounting groove 2111 in the horizontal direction, the mounting portion 212 is welded at the opening of the U-shaped plate 211, and the mounting portion 212 is provided with a second mounting groove 2121 arranged parallel to the first mounting groove 2111 in the vertical direction, the telescopic drive member 221 can be inserted into the first mounting groove 2111 and the second mounting groove 2121, and the bottom of the sleeve 2211 is connected to the mounting portion 212 through the second mounting groove 2121.

[0048] More specifically, in one embodiment, the bottom of the sleeve 2211 is connected to the mounting portion 212 by bolts.

[0049] In this way, when the aerial work platform is raised, the telescopic portion 2212 of the telescopic drive member 221 moves downward relative to the sleeve 2211 until the telescopic portion 2212 contacts the ground, thereby ensuring greater operational stability for the aerial work platform during lifting. Since the bottom of the sleeve 2211 is detachably fixedly connected to the leg support 210, the leg body 220 can be fixedly connected to the leg support 210. The leg support 210 can then provide support for the leg body 220 during operation, thereby ensuring operational stability for the leg body 220. Furthermore, since the telescopic drive member 221 can be inserted into the first mounting slot 2111 and the second mounting slot 2121, the first mounting slot 2111 and the second mounting slot 2121 can serve as a limiting guide for the telescopic drive member 221, thereby ensuring greater operational stability when the telescopic drive member 221 moves up and down relative to the leg support 210.

[0050] like Figure 1 、 Figure 2 As shown, in one embodiment, the telescopic driving member 221 is a telescopic oil cylinder.

[0051] When the telescopic cylinder is not working, it can meet the requirement of keeping the legs away from the ground to ensure that the aerial work platform will not be affected by the legs during movement. The telescopic cylinder has the advantage of a large working stroke when working, and can meet the requirements of chassis of different sizes and heights, ensuring that the telescopic part 2212 can be offset from the ground during work, thereby ensuring the operating stability of the aerial work platform during lifting.

[0052] like Figure 1 、 Figure 2 As shown, in one embodiment, the leg body 220 also includes a first protective shell 222 and a second protective shell 223, and the first protective shell 222 and the second protective shell 223 are arranged around the front and rear sides or the left and right sides of the sleeve 2211. The edge of the first protective shell 222 and the edge of the second protective shell 223 are detachably connected, and the lower end of the first protective shell 222 and / or the second protective shell 223 is detachably fixedly connected to the leg support 210; wherein, the telescopic part 2212 can move up and down relative to the first protective shell 222 and the second protective shell 223.

[0053] Specifically, the first protective shell 222 and the second protective shell 223 are disposed around the front and rear sides or the left and right sides of the sleeve 2211 to form an integral protective shell.

[0054] In this way, the protective shell as a whole can protect the telescopic drive member 221 from damage, and can further play a certain limiting and guiding role for the telescopic drive member 221, ensuring that the telescopic drive member 221 can move up and down in the vertical direction. In addition, because the edge of the first protective shell 222 and the edge of the second protective shell 223 are detachably connected, when repairing the leg assembly 200, the leg assembly 200 can be repaired by separating the first protective shell 222 from the second protective shell 223. The segmented protective shell is lighter in weight and has the advantage of being more convenient when repairing the leg assembly 200 than a monolithic, non-detachable protective shell.

[0055] like Figure 1 、 Figure 2 As shown, in one embodiment, the leg body 220 also includes a guide member 224, which is arranged at the top of the telescopic driving member 221, and a guide hole 225 is provided at the top of the second protective shell 223 or the first protective shell 222, and the guide member 224 is passed through the guide hole 225.

[0056] Specifically, the guide member 224 is a guide rod vertically arranged on the top of the telescopic driving member 221.

[0057] Since the first protective shell 222 and the second protective shell 223 are both fixedly connected to the leg support 210, and the guide member 224 is passed through the guide hole 225, the cooperation between the guide member 224 and the guide hole 225 can further play a limiting and guiding role on the telescopic drive member 221, so that the telescopic drive member 221 can move up and down in the vertical direction, ensuring the operating stability of the leg assembly 200 when the aerial work platform is lifted on muddy potholes, inclined surfaces, etc., further improving the operating stability of the aerial work platform during lifting.

[0058] like Figure 1 、 Figure 3 as well as Figure 4 As shown, in one embodiment, there are two first reinforcement members 310, the two first reinforcement members 310 are arranged side by side and spaced apart in the vertical direction, and the first reinforcement members 310 are fixedly connected to the connecting plate and the support plate. The reinforcement assembly 300 also includes a second reinforcement member 320, which is fixedly connected between the two first reinforcement members 310.

[0059] Specifically, the angle between the two side surfaces of the first reinforcement 310 near the connection between the connecting plate and the support plate is the same as the angle between the connecting plate and the support plate, that is, the two first reinforcements 310 are arranged side by side in the vertical direction at the connection between the connecting plate and the support plate.

[0060] Furthermore, the second reinforcement member 320 is provided at the connection between the connecting plate and the supporting plate, and one end of the second reinforcement member 320 is close to the supporting plate, and the other end of the second reinforcement member 320 is close to the connecting plate.

[0061] More specifically, the first reinforcement 310 is connected to the connecting plate and the supporting plate by welding, and the second reinforcement 320 is connected to the first reinforcement 310 by welding.

[0062] During the lifting process of the aerial work platform, the leg assembly 200 applies a force to the connecting plate, which may cause the connecting plate to deform at the connection with the support plate. Since the two first reinforcement members 310 are arranged vertically side by side at the connection between the connecting plate and the support plate, the two first reinforcement members 310 can provide the connecting plate with a counterforce relative to the force applied to the connecting plate by the leg assembly 200, making the connection between the connecting plate and the leg assembly 200 more stable, thereby ensuring better operational stability of the aerial work platform during lifting. In addition, since the second reinforcement member 320 is fixedly connected between the two first reinforcement members 310, the second reinforcement member 320 can enhance the support function of the first reinforcement member 310, making the connection between the first reinforcement member 310 and the connecting plate and the support plate more stable, thereby further enhancing the support function of the reinforcement assembly 300 on the connecting plate and preventing deformation of the connecting plate, thereby further ensuring a more stable connection between the connecting plate and the leg assembly 200, and ensuring better operational stability of the aerial work platform during lifting.

[0063] like Figure 1 、 Figure 3 As shown, in one embodiment, the connecting plate includes a first connecting plate 110 and a second connecting plate 120 arranged parallel to and spaced apart from the first connecting plate 110, the supporting plate includes a first supporting plate 130 and a second supporting plate 140 arranged parallel to and spaced apart from the first supporting plate 130, both ends of the first supporting plate 130 are connected to the first connecting plate 110 and the second connecting plate 120, and both ends of the second supporting plate 140 are also connected to the first connecting plate 110 and the second connecting plate 120, the first connecting plate 110 is arranged at the front end of the base frame body 100, and the second connecting plate 120 is arranged at the rear end of the base frame body 100, and both ends of the first connecting plate 110 and the second connecting plate 120 protrude from the base frame body 100; wherein, both ends of the first connecting plate 110 and the second connecting plate 120 are provided with support leg assemblies 200, and both ends of the first connecting plate 110 and the second connecting plate 120 are provided with reinforcement assemblies 300 arranged back to the support leg assemblies 200.

[0064] Thus, the above-mentioned chassis has four leg assemblies 200 arranged at both ends of the first connecting plate 110 and the second connecting plate 120, and the above-mentioned chassis has four reinforcement assemblies 300 arranged opposite the leg assemblies 200. Because the four leg assemblies 200 are arranged at the four diagonal corners of the chassis body 100 and all four leg assemblies 200 protrude from the chassis body 100, when the aerial work platform is lifted, the four leg assemblies 200 can simultaneously contact the ground, thereby enhancing the stability of the above-mentioned chassis during operation, thereby enhancing the operational stability of the aerial work platform during lifting. In addition, because the four reinforcement assemblies 300 are arranged opposite the four leg assemblies 200 in a one-to-one correspondence, the operational stability of the above-mentioned chassis can be further enhanced.

[0065] like Figure 1 、 Figure 3 As shown, in one embodiment, the base frame also includes a door box 400 and a control panel 500 arranged on the door box 400, and the front end of the base frame body 100 is provided with a mounting groove 150, and the door box 400 can be movably connected to the front end of the base frame body 100 so that the notch of the mounting groove 150 can be opened or closed.

[0066] Specifically, in one embodiment, the bottom of the door box 400 is bent at a certain angle to provide an approach angle for the vehicle, and the top and left and right sides of the door box 400 are bent 90 degrees each to prevent dust and water.

[0067] Furthermore, in one embodiment, the left and right side walls of the mounting groove 150 are provided with slide grooves (not shown), and the left and right sides of the door box 400 are provided with sliders (not shown) correspondingly. Each slider can slide back and forth in the corresponding slide groove, so that the door box 400 can move back and forth in the mounting groove 150, thereby opening or closing the notch of the mounting groove 150. In addition, in other embodiments, the door box 400 can also be movably connected to the mounting groove 150 via a connecting shaft (not shown). The connecting shaft is located at the connection between one of the left and right side walls of the mounting groove 150 and the first connecting plate 110. The door box 400 can rotate counterclockwise or clockwise around the connecting shaft, so that the door box 400 can enter the mounting groove 150 or move away from the mounting groove 150, thereby opening or closing the notch of the mounting groove 150.

[0068] Since the control panel 500 is arranged at the front end of the base frame body 100 and the control panel 500 is arranged on the door box 400, the circuits inside the control panel 500 can be directly connected to the components in the door box 400. Compared with the control panel 500 arranged on the side of the base frame body 100 and far away from the door box 400, it has the advantage of being easier to operate during operation, maintenance and system upgrades.

[0069] like Figure 1 、 Figure 5 As shown, in one embodiment, the chassis also includes a supporting beam 600 and two tracks 700. The two tracks 700 are arranged side by side and spaced apart on the left and right sides of the chassis body 100. The two ends of the supporting beam 600 are respectively and detachably fixedly connected to the middle of the two tracks 700, and the two ends of the supporting beam 600 are detachably connected to the chassis body 100.

[0070] Specifically, the support beam 600 is connected to the crawler track 700 and the chassis body 100 by bolts.

[0071] The two ends of the support beam 600 are detachably fixedly connected to the middle of the two crawlers 700. Therefore, when the aerial work platform is moving, the support beam 600 can serve as a limiting and guiding role for the two crawlers 700, so that the two crawlers 700 can reduce the travel deviation during the movement. Because the two ends of the support beam 600 are detachably connected to the chassis body 100, the support beam 600 can provide support for the two crawlers 700, making the connection between the two crawlers 700 and the chassis body 100 more stable during the movement. In addition, since the support beam 600 is detachably connected to the crawlers 700 and the chassis body 100, it has the advantage of being more convenient when replacing and repairing the crawlers 700.

[0072] An aerial work platform according to one embodiment includes the above-described underframe.

[0073] In the above-mentioned aerial work platform, since the base frame body 100 and the leg assembly 200 have better connection stability, the above-mentioned base frame has better operating stability, and thus the above-mentioned aerial work platform has better operating stability during lifting.
