[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The present invention discloses a support device for a loader hood, which is used to support the hood 1, keep the hood 1 in an open state and expose the radiator 3, so as to facilitate maintenance personnel to perform maintenance and repair operations on the radiator 3. When the radiator 3 is working normally, the hood 1 covers the radiator. When the radiator needs to be overhauled or repaired, the hood 1 is turned upwards. The hood 1 rotates upwards around the rotating shaft 2 to complete the opening of the hood 1. To prevent the hood 1 from resetting due to an accident during the overhaul of the radiator, a support device for the loader hood of the technical solution of the present invention is specifically provided. This support device 4 is used to support the opened hood, ensure that the hood remains in an open state, and even if an accident occurs, the hood will not accidentally reset and close, ensuring the safety of the maintenance personnel at the radiator position.

[0035] Such as Figure 1As shown in the figure, a loader hood support device includes a fixed base 5, a fixed connecting piece 15, and a rigid support body 7. The fixed base is fixedly installed on the radiator 3. The rigid support body 7 is detachably connected to the fixed base 5 through the fixed connecting piece. When the hood 1 rotates upward to open, the rigid support body 7 is fixedly installed on the fixed base 5 through the fixed connecting piece, and the rigid support body 7 maintains the state of supporting the hood 1. When the hood 1 is closed, the rigid support body 7 is detached from the fixed base 5 and fixedly stored on the radiator 3 and is located inside the hood 1.

[0036] Based on the above solution, the rigid support body 7 is connected to the fixed base through the provided fixed connecting piece, enabling the rigid support body 7 to be in a supporting working state to support the opened hood, avoiding the problem of accidental closing of the hood, and preventing accidental injury to the maintenance and repair staff at the radiator.

[0037] It should be noted here that the rigid support body 7 is fixedly connected to the fixed base through the fixed connecting piece. The rigid support body 7 itself can maintain the supporting posture and state. When the hood is opened, the rigid support body 7 can directly support the hood, or the hood can be opened to the maximum opening state. If problems such as accidental fracture occur to the rotating shaft 2 on the hood, and the hood accidentally resets and closes, when the hood encounters the rigid support body 7 of this support device 4 during the closing process, it can be blocked and intercepted by the rigid support body 7 to support the hood, preventing the hood from continuing to close downward, providing sufficient living space for the staff at the radiator, and ensuring the personal safety of the maintenance and repair staff.

[0038] When the hood is directly opened to the maximum state, it can provide a larger operating space for the maintenance and repair staff at the radiator, facilitating the maintenance and repair operations of the staff, and enabling the maintenance and repair operations to be free from the restrictions and interferences of the hood and the support device 4.

[0039] When the hood is closed, by operating the fixed connecting piece 15, the rigid support body is actively detached from the fixed base, enabling the hood to be normally closed. At the same time, the rigid support body 7 can be fixedly stored on the radiator and is located inside the hood, without affecting the normal operation and use of the radiator and the hood, and also without causing the loss of the rigid support body 7.

[0040] In this technical solution, a connecting plate 6 is provided on the fixed base 5. The rigid support body 7 is fixedly connected to the fixed base 5 by the fixed connecting piece passing through the rigid support body 7 and the connecting plate 6.

[0041] The fixed base is fixedly connected to the radiator, which can be connected by welding or locking connectors such as connecting bolts. A connecting plate 6 is provided to facilitate the connection with the rigid support 7. Generally, there are two relatively arranged connecting plates. One end of the rigid support 7 is placed between the two connecting plates, and then the rigid support 7 is fixedly connected to the connecting plates through the fixed connectors passing through the two connecting plates and the rigid support 7.

[0042] The fixed base is fixedly connected to the radiator, that is, this support device can be installed on the existing radiator, with strong adaptability, without affecting the existing radiator and the engine hood, low cost, and easy to promote and use.

[0043] In this technical solution, at least two first connection holes are provided on the connecting plate 6, and the fixed connector passes through the first connection holes. By setting at least two first connection holes, the fixed connection between the rigid support 7 and the connecting plate is ensured, and it is ensured that the rigid support 7 can maintain a vertical support state after being connected to the connecting plate. Of course, on the connecting plate, the first connection holes should not be set too many, otherwise it will affect the strength of the connecting plate. Generally, it is best to set two or three first connection holes on the connecting plate.

[0044] In this technical solution, the rigid support 7 includes a support rod 9, an insertion plate 12 and a support clamping plate 8. The insertion plate 12 and the support clamping plate 8 are respectively fixedly connected to both ends of the support rod 9, and the insertion plate 12 is detachably fixedly connected to the fixed base 5 through the fixed connector; when the engine hood 1 rotates upward to open, the support clamping plate 8 faces the engine hood 1 and supports the engine hood 1 to keep it in the open state.

[0045] The insertion plate 12 and the support clamping plate 8 are respectively fixedly connected to both ends of the support rod 9, which improves the strength of the rigid support, and at the same time facilitates the fixed connection between the rigid support and the fixed base, and facilitates the support of the engine hood by the rigid support. By setting an insertion plate on the rigid support, it is convenient for the connection between the rigid support and the connecting plate, simplifies the connection operation, and provides an obvious mark for the connection part.

[0046] In the above solution, preferably, to further improve the strength of the rigid support 7, the support rod 9, the insertion plate 12 and the support clamping plate 8 are integrally formed or welded.

[0047] In this technical solution, at least two second connection holes 16 are provided on the insertion plate 12, and the fixed connector 15 passes through the second connection holes 16 to realize the fixed connection between the rigid support 7 and the connecting plate 6. The second connection holes 16 are adapted to the first connection holes to realize the detachable fixed connection between the insertion plate and the connecting plate. By setting the second connection holes to be adapted to and connected with the first connection holes, the connection operation is simple, and after connection, the support rod 9 can maintain a vertical support state to support the opened engine hood or prevent the accidental closing of the opened engine hood.

[0048] In addition, a first connection hole and a second connection hole are provided and connected by a fixing connector, which facilitates the disassembly of the support rod 9 after installation and facilitates the storage of the support rod 9 on the radiator.

[0049] In this technical solution, when the rigid support body is not in use or not performing support, it is detached from the fixed base 5 and then stored on the radiator. In this way, the installation position of the fixed base on the radiator is less restricted, and it can be set at the most suitable position according to needs, such as near the edge of the radiator, to avoid interference with the maintenance of the radiator by the rigid support body, or set at a position relatively close to the middle of the radiator to support the hood from a relatively middle position of the hood, improving the support strength and reliability of the hood.

[0050] In this technical solution, a U-shaped notch 81 is provided on the support card plate 8. When the hood 1 rotates upward and opens, the notch faces the hood 1 and supports the hood 1. The U-shaped notch 81 is provided on the support card plate 8 to provide a receiving position for the support of the hood, facilitating the support of the hood and avoiding problems such as slipping between the support card plate 8 and the hood, resulting in support failure or unstable support.

[0051] In this technical solution, the fixing connector 15 is a pin shaft, which has a simple structure, low cost, and is convenient and fast for installation connection and disassembly.

[0052] In this technical solution, the support device 4 further includes a storage fixing member, and the storage fixing member includes a locking plate 11 provided on the support rod 9 and a first clamping plate 14 provided on the radiator 3. After the rigid support body is stored on the radiator, the first clamping plate 14 is adapted to the locking plate 11, at least restricting the axial movement of the rigid support body.

[0053] The first clamping plate is used to limit the locking plate on the support rod 9, and at least limit the axial movement of the rigid support body, avoiding problems such as shaking or crosstalk of the rigid support body stored on the radiator during the operation of the radiator, and preventing the rigid support body from slipping off the radiator, affecting the normal operation of the radiator, or even affecting the normal operation of the loader.

[0054] Based on the above solution, as Figure 5 shown, the locking plate is fixedly connected to the support rod and is provided with at least one third connection hole. After the rigid support body is stored on the radiator, the locking plate is parallel to the first clamping plate, and the locking plate abuts against the first clamping plate. The first clamping plate is provided with a fourth connection hole adapted to the third connection hole. The locking plate and the first clamping plate are detachably and fixedly connected by a locking connector passing through the third connection hole and the fourth connection hole.

[0055] The axial direction of the third connection hole is parallel to the axial direction of the support rod after being received. The locking connecting piece can generally be a connecting bolt, a connecting pin shaft, etc., to realize the fixed connection of the locking plate and the first clamping plate together, restrict the shaking of the support rod, avoid the shaking of the support rod along with the operation of the radiator, and enable the support rod to be received on the radiator at the specified position.

[0056] In this technical solution, the receiving and fixing piece further includes a limiting plate 10 provided on the support rod and a second clamping plate 13 provided on the radiator. After the rigid support body is received on the radiator, the second clamping plate 13 is adapted to the limiting plate 10 to at least restrict the radial movement of the rigid support body. As Figure 4 shown, a limiting groove is provided on the second clamping plate, and the limiting groove is arranged along the radial direction of the rigid support body. After the rigid support body is received on the radiator, the limiting plate is placed in the limiting groove. As Figure 4 shown, after the limiting plate 10 is inserted into the limiting groove, the limiting groove restricts the shaking of the support rod, further realizes the restriction of the movement and shaking of the support rod, enables the support rod to be received on the radiator, avoids the problem of the rigid support body falling off the radiator, and avoids the problems of rolling or shaking of the rigid support member 7 resulting in noise or affecting the operation of the radiator.

[0057] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include the technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
