Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and more particularly to an operation platform and a crane. Background Art

[0002] Traditional cranes are mainly used for operations such as hoisting and transporting materials. However, during the hoisting operation in some environments, operators need to perform some high-altitude operations. However, traditional cranes do not have the conditions for operators to perform high-altitude operations, so a high-altitude work vehicle needs to be equipped again during the operation to achieve high-altitude operations, which greatly increases the use cost and labor cost.

[0003] Therefore, there is an urgent need to provide an operation platform to solve the problems existing in the prior art to a certain extent. Summary of the Invention

[0004] The purpose of the present invention is to provide an operation platform and a crane to strengthen the high-altitude operation ability of the crane to a certain extent and reduce the use cost.

[0005] The present invention provides an operation platform for a crane, including a platform body, a telescopic mechanism, and a mounting frame; the mounting frame is arranged at one end of the boom of the crane far from the cab, the platform body is rotatably connected to the mounting frame through a connecting component; the telescopic mechanism is connected between the mounting frame and the platform body, the telescopic end of the telescopic mechanism is rotatably connected to the platform body, and the other end is connected to the mounting frame; the telescopic mechanism can extend or contract to push the platform body to rotate relative to the mounting frame.

[0006] Wherein, the mounting frame includes a first support plate and a second support plate connected in an L shape; the second support plate is connected to the side arm of the boom, and the first support plate is used for mounting the platform body.

[0007] Specifically, the connecting component includes a first connecting portion connecting the platform body and a second connecting portion connecting the mounting frame, and the first connecting portion is rotatably connected to the second connecting portion so that the platform body can rotate relative to the mounting frame.

[0008] Wherein, the first connecting portion and the second connecting portion are correspondingly arranged and extend towards each other, so that the platform body is erected above the mounting frame, and the platform body has a rotating space relative to the mounting frame.

[0009] Specifically, the number of the connecting components is multiple, and the rotation axes of the multiple connecting components are collinear; connecting holes are formed in the first connecting portion and the second connecting portion, and a connecting shaft is arranged in the connecting holes to rotatably connect the first connecting portion and the second connecting portion.

[0010] Further, the connecting shaft is a pin shaft.

[0011] Furthermore, the telescopic end of the telescopic mechanism is rotatably connected to the platform body, and the rotation axis of the telescopic mechanism is parallel to the rotation axis of the connection assembly.

[0012] Wherein, the working platform provided by the present invention further includes a ladder. One end of the ladder is connected to the side wall of the platform body, and the other end can contact the ground when the boom is in the horizontal direction.

[0013] Specifically, the ladder is located on the side of the platform body facing the cab, and the ladder is a telescopic ladder; when the boom is lifted, the ladder can be retracted towards the direction close to the platform body.

[0014] Compared with the prior art, the working platform provided by the present invention has the following advantages:

[0015] The working platform provided by the present invention is used for a crane and includes a platform body, a telescopic mechanism and a mounting frame; the mounting frame is arranged at the end of the boom of the crane away from the cab, and the platform body is rotatably connected to the mounting frame through a connection assembly; the telescopic mechanism is connected between the mounting frame and the platform body, the telescopic end of the telescopic mechanism is rotatably connected to the lower wall surface of the platform body, and the other end is connected to the mounting frame; the telescopic mechanism can extend or contract to push the platform body to rotate relative to the mounting frame.

[0016] It can be analyzed from this that by arranging the mounting frame at the end of the boom away from the cab, and by the telescopic mechanism, the first connection part and the second connection part, the platform body is erected above the mounting frame. On the one hand, it can avoid the interference of the working platform provided by the present application to the hoisting operation of the crane, and on the other hand, it can also enable the platform body to stably carry operators for high-altitude operations.

[0017] Moreover, the present application provides a first connection part and a second connection part with rotational connection and a telescopic mechanism with a telescopic end rotatably connected to the platform body, which can change the angle of the platform body through the expansion and contraction of the telescopic end of the telescopic mechanism, so as to meet the requirement that the platform body always remains consistent with the horizontal plane, and improve the operation safety and stability of the operators.

[0018] In addition, the present invention also provides a crane including the above-mentioned working platform.

[0019] In the above technical solution, by providing a mounting frame, a telescopic mechanism and a platform body at one end of the boom away from the crane cab, an operator can enter the platform body and reach a specified high-altitude position following the lifting of the boom to complete a specified task. Moreover, by telescoping the telescopic mechanism, the angle between the platform body and the horizontal direction is changed, enabling the working platform to always be consistent with the horizontal plane, thereby enhancing the high-altitude operation ability of the traditional crane to a certain extent.

[0036] As Figures 1 - 3 shown, the present invention provides a work platform for a crane, including a platform body 1, a telescopic mechanism 2, and a mounting bracket 3; the mounting bracket 3 is disposed at one end of the boom 8 of the crane away from the cab 9, the platform body 1 is disposed on the mounting bracket 3, and a connection assembly is provided between the platform body 1 and the mounting bracket 3. The connection assembly includes a first connection portion 4 and a second connection portion 5, and the first connection portion 4 is rotatably connected to the second connection portion 5; the telescopic mechanism 2 is disposed between the mounting bracket 3 and the platform body 1, the telescopic end of the telescopic mechanism 2 is rotatably connected to the lower wall surface of the platform body 1, and the other end is connected to the mounting bracket 3; the platform body 1 is erected above the mounting bracket 3 through the telescopic mechanism 2, the first connection portion 4, and the second connection portion 5, and the telescopic mechanism 2 can push the platform body 1 to be flush with the horizontal plane.

[0037] Compared with the prior art, the work platform provided by the present invention has the following advantages:

[0038] For the work platform provided by the present invention, by disposing the mounting bracket 3 at one end of the boom 8 away from the cab 9, and erecting the platform body 1 above the mounting bracket 3 through the telescopic mechanism 2, the first connection portion 4, and the second connection portion 5, on the one hand, it can avoid the interference of the work platform provided in the present application to the lifting operation of the crane, and on the other hand, it also enables the platform body 1 to stably carry operators for high-altitude operations.

[0039] Moreover, the present application is provided with a first connecting portion 4 and a second connecting portion 5 that are rotatably connected, and a telescopic mechanism 2 whose telescopic end is rotatably connected to the platform body 1. The telescopic end of the telescopic mechanism 2 can be telescoped to change the angle of the platform body 1, so as to meet the requirement that the platform body 1 is always kept parallel to the horizontal plane, and improve the operation safety and stability of the operator.

[0040] In the present application, to ensure the stability of the platform body 1, one end of the telescopic mechanism 2 is fixedly connected to the mounting frame 3. Since the rotation of the platform body 1 is realized by the telescoping of the telescopic end, the telescopic end is rotatably connected to the platform body 1, which can adapt to the angle change between the telescopic end and the platform body 1.

[0041] When the boom 8 of the crane is lifted, the telescopic end of the telescopic mechanism 2 extends, causing the platform body 1 to rotate relative to the mounting frame 3, so that the platform body 1 can always be kept parallel to the horizontal plane.

[0042] It should be noted here that preferably, in the present application, the telescopic mechanism 2 is a telescopic oil cylinder, but an electric telescopic boom or other structures can also be selected to keep the platform body 1 horizontal. An installation plate 10 extending towards the mounting frame 3 is provided on the lower wall surface of the platform body 1. The telescopic end of the telescopic oil cylinder is rotatably connected to the installation plate 10 through a pin shaft, and the installation plates 10 are arranged in one-to-one correspondence with the telescopic oil cylinders.

[0043] Among them, as Figures 1 - 3 shown, the mounting frame 3 is L-shaped, including a first support plate 301 and a second support plate 302; the first support plate 301 is arranged horizontally, the second support plate 302 is arranged vertically, and the second support plate 302 is connected to the side arm of the boom 8. The first support plate 301 is used for mounting the platform body 1.

[0044] In the present application, the mounting frame 3 is connected to the boom 8 through the second support plate 302, and the second support plate 302 is detachably connected to the boom 8 through structures such as bolts, thereby realizing the detachable connection between the mounting frame 3 and the boom 8.

[0045] When the crane does not need to perform high-altitude operations, the mounting frame 3 is removed. When high-altitude operations are required, the mounting frame 3 is installed on the boom 8 to realize high-altitude operations.

[0046] Setting the mounting frame 3 as L-shaped in the present application can also facilitate the disassembly and assembly between the mounting frame 3 and the boom 8 and the installation between the platform body 1 and the mounting frame 3.

[0047] Preferably, in the present application, the mounting frame 3 is arranged on the side wall surface of the boom 8, so as to avoid the influence on the hoisting process to a certain extent after the boom 8 is installed with the operation platform.

[0048] Specifically, as Figures 1 - 3As shown, the first connecting part 4 and the second connecting part 5 are correspondingly arranged and extend towards each other, so that the platform body 1 has a rotating space relative to the mounting frame 3.

[0049] The rotation of the platform body 1 relative to the mounting frame 3 is realized by arranging the first connecting part 4 and the second connecting part 5 which are rotatably connected between the platform body 1 and the mounting frame 3. In this application, by arranging the first connecting part 4 and the second connecting part 5 to extend towards each other, the platform body 1 can be erected above the mounting frame 3, so that it has a rotating space relative to the mounting frame 3. Furthermore, when the boom 8 is lifted and the telescopic end of the telescopic mechanism 2 extends, the platform body 1 can be leveled to keep the platform body 1 consistent with the horizontal plane, improving the stability and safety of the overall device.

[0050] It should be supplemented and explained here that preferably in this application, the number of the second connecting parts 5 included in one connecting component is two, and the number of the first connecting parts 4 is one. The first connecting part 4 is arranged between the second connecting parts 5, thus improving the connection strength and stability between the platform body 1 and the mounting frame 3; it can also be that the number of the first connecting parts 4 is two and the number of the second connecting parts is one, and the second connecting part 5 is arranged between the two first connecting parts 4. The first connecting part 4 and the second connecting part 5 are fixedly connected to the corresponding platform body 1 and mounting frame 3 by welding or other means.

[0051] Specifically, as Figures 1 - 3 shown, the number of the connecting components is multiple, and the multiple connecting components are arranged along the first direction S1.

[0052] It should be supplemented and explained here that the first direction S1 in this application is the extending direction of the first support plate 301. Figure 2 The first direction S1 shown is only an example of the arrangement direction of the multiple connecting components in this embodiment, and is not a limitation on the specific arrangement direction of the connecting components. The connecting components arranged along the first direction S1 only need to satisfy that they are not collinear with the mounting plate 10.

[0053] Connecting holes are formed in the first connecting part 4 and the second connecting part 5, and the centers of the connecting holes are located on the same straight line; a connecting shaft 6 is arranged in the connecting holes, and the connecting shaft 6 rotatably connects the first connecting part 4 and the second connecting part 5. Preferably, the connecting shaft 6 is a pin shaft.

[0054] Preferably in this application, the number of the connecting components is two, the corresponding number of the first connecting parts 4 is two, and the number of the second connecting parts 5 is four, and they are all arranged along the first direction S1, so that the centers of the connecting holes on the first connecting part 4 and the second connecting part 5 are located on the same straight line, that is, the rotation axes of the two connecting components are collinear, so as to enable the stable rotation of the platform body 1, and further ensure that the platform body 1 can better keep consistent with the horizontal plane, improving the safety of the operator.

[0055] Moreover, preferably in the present application, the two first connecting portions 4 and the mounting plate 10 are arranged in a triangular pattern on the lower wall surface of the platform body 1, so that the platform body 1 can be stably erected above the mounting frame 3.

[0056] In the present application, the first connecting portion 4 and the second connecting portion 5 are rotatably connected by a pin shaft. Using a pin shaft can quickly achieve the rotational connection between the first connecting portion 4 and the second connecting portion 5. Moreover, when maintenance operations such as those on the platform body 1 or the mounting frame 3 are required, the pin shaft can also be removed to separate the platform body 1 from the mounting frame 3, achieving quick disassembly, assembly, and maintenance. However, the rotational connection between the first connecting portion 4 and the second connecting portion 5 in the present application can also be achieved through a shaft and bearing or a spherical joint, etc.

[0057] Specifically, as Figures 1 - 3 shown, the telescopic mechanism 2 is arranged perpendicular to the mounting frame 3 and is located on the side of the mounting frame 3 facing the cab 9, and the first connecting portion 4 and the second connecting portion 5 are located on the other side of the platform body 1 and the mounting frame 3, so that the platform body 1 can be leveled.

[0058] In an embodiment of the present application, the telescopic mechanism 2 is arranged perpendicular to the mounting frame 3 and the platform body 1, and the telescopic mechanism 2 is located on the side facing the cab 9, and the connecting assembly is located on the other side and is arranged in a triangular pattern.

[0059] Arranging the telescopic mechanism 2 perpendicular to the side of the mounting frame 3 close to the cab 9 and in a triangular pattern with the connecting assembly can improve the stability of the platform body 1 and the supporting strength of the telescopic mechanism 2 for the platform body 1, and avoid the problem of fracture at the connection between the telescopic mechanism 2 and the mounting frame 3.

[0060] It should be supplemented and explained here that in this embodiment, the number of telescopic mechanisms 2 can be multiple, and preferably, they are evenly distributed on the mounting frame 3, thereby further improving the stability and supporting strength of the platform body 1.

[0061] Specifically, as Figures 1 - 3 shown, the first connecting portion 4 is located at the middle position of the platform body 1, the second connecting portion 5 is located at the middle position of the mounting frame 3, and the telescopic end of the telescopic mechanism 2 and the connecting end of the platform body 1 are located on the side of the platform body 1 facing the cab 9, so that the working platform can be leveled.

[0062] In another embodiment of the present application, the second connecting portion 5 is located at the middle position of the mounting frame 3, the telescopic mechanism 2 can be multiple, and the corresponding mounting plates 10 for the telescopic mechanism 2 are multiple. A part of the multiple mounting plates 10 is arranged on the side of the platform body 1 away from the cab 9, and the other part is arranged on the side close to the cab 9.

[0063] When the boom 8 of the crane is lifted, the telescopic end of the telescopic mechanism 2 rotatably connected to the mounting plate 10 on the side close to the cab 9 extends, and the telescopic end of the telescopic mechanism 2 rotatably connected to the mounting plate 10 on the side away from the cab 9 contracts, thereby realizing the leveling of the platform body 1.

[0064] Among them, as Figures 1 - 3 shown, the working platform provided by the present invention further includes a ladder 7. One end of the ladder 7 is connected to the side wall of the platform body 1, and the other end can be in contact with the ground when the boom 8 is in the horizontal direction.

[0065] When the crane is in a non-working state, the boom 8 is in the horizontal direction. However, since the crane has a certain height, therefore, by providing the ladder 7 in this application, the operator can more conveniently enter the platform body 1 from the ground or descend from the platform body 1 to the ground.

[0066] Specifically, as Figures 1 - 3 shown, the ladder 7 is located on the side of the platform body 1 facing the cab 9 and is a telescopic ladder; when the boom 8 is raised, the ladder 7 can be retracted towards the direction close to the platform body 1.

[0067] Preferably in this application, the telescopic ladder is an electric telescopic ladder, which has two electric telescopic rods in the vertical direction, and a plurality of cross beams are provided between the two electric telescopic rods, thereby forming an electric telescopic ladder.

[0068] Since the ladder 7 in this application is an electric telescopic ladder, therefore, by arranging the ladder 7 on the side of the platform body 1 facing the cab 9, it is convenient for the driver to control the telescoping of the electric telescopic ladder 7, thereby to a certain extent avoiding the influence of the ladder 7 on the lifting during the working state of the crane.

[0069] In addition, as Figures 1 - 3 shown, the present invention also provides a crane, including the above-mentioned working platform.

[0070] When the crane provided in this application is in a non-working state, the boom 8 of the crane is in a horizontal state. At this time, both the platform body 1 and the mounting frame 3 are in a horizontal state.

[0071] When the crane is in a working state and the boom 8 is raised and forms a certain angle with the horizontal plane, the telescopic end of the telescopic mechanism 2 extends, thereby pushing the side of the platform body 1 close to the cab 9, enabling the platform body 1 to rotate relative to the mounting frame 3, and further ensuring that the platform body 1 always remains parallel to the horizontal plane.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
