Description

Technical Field

[0001] This application belongs to the field of outrigger technology for engineering vehicles, specifically an outrigger for engineering vehicles. Background Technology

[0002] In the field of construction machinery technology, outriggers are generally used on construction vehicles to enhance stability during operation and prevent tipping. However, the outriggers need to be retracted into their final positions and locked in place during travel to prevent them from extending due to inertia and causing danger. Therefore, outriggers are usually equipped with a dedicated, manually operated outrigger locking device. This can be achieved by using a chain to anchor the retracted outrigger to the fixed structure of the equipment, or by using a manual locking tongue to achieve either a limiting or unlocked function.

[0003] For example, application CN216508288U discloses an outrigger for engineering vehicles, including a primary convergence shell, a secondary convergence shell, and a supporting hydraulic column, which are nested together and hinged to adjacent components. Both the primary and secondary convergence shells are U-shaped plates, with the primary shell opening to the right and the secondary shell opening downwards. The outer side of the secondary convergence shell is connected to the primary convergence shell via a hydraulic rod, and the inner side of the secondary convergence shell is connected to the supporting hydraulic column via a hydraulic rod. By adjusting the length of the hydraulic rod, the secondary convergence shell and the supporting hydraulic column can be unfolded / folded. This utility model uses the aforementioned outrigger, setting the support structure to be foldable, significantly reducing the floor space required, thus facilitating the entry and exit of large engineering vehicles into narrow working environments.

[0004] However, the bottom of the outrigger for the engineering vehicle in the application is not stable and it is difficult to keep it in a horizontal state, making it difficult to maintain a stable state when the engineering vehicle is in use. Now, an outrigger for the engineering vehicle that can increase the bottom stability is provided. Utility Model Content

[0005] The purpose of this application is to provide an outrigger for engineering vehicles, in order to solve the problem that the bottom of the outriggers for engineering vehicles is not stable and it is difficult to maintain a horizontal state, and it is difficult to maintain a stable state when the engineering vehicle is in use.

[0006] The technical solution adopted in this application is as follows: an outrigger for an engineering vehicle, wherein a limit rod is fixedly installed on the surface of the horizontal outrigger fixing block, and a second horizontal outrigger fixing block is movably installed at the end of the limit rod; a vertical outrigger fixing block is welded to the lower surface of the second horizontal outrigger fixing block; a branch arm mounting plate is fixedly installed at the edge of the surface of the vertical outrigger fixing block away from the horizontal outrigger fixing block; a hole is opened on the surface of the branch arm mounting plate, and a branch arm fixing column is movably installed in the hole; a branch arm is movably installed on the surface of the branch arm fixing column; a limit block is fixedly installed at the edge of the surface of the branch arm; a vertical hydraulic rod is fixedly installed on the lower surface of the limit block; and a load-bearing chassis is fixedly installed on the lower surface of the vertical hydraulic rod.

[0007] By adopting the above technical solution, the commonly used process vehicle outrigger has only one outrigger, which is unstable when encountering uneven ground during use, affecting work efficiency. After the branch arm is installed, the vertical hydraulic rod of this device can be adjusted up and down to adapt to engineering vehicles of different heights, and the load-bearing chassis can support the weight of the device body.

[0008] In a preferred embodiment, a branch arm mounting hole is provided on the surface of the branch arm in the area corresponding to the limiting block.

[0009] By adopting the above technical solution, the design of the branch arm mounting hole allows the branch arm to be adjusted at any position and angle, and the two branch arms allow the engineering vehicle to maintain a more stable working state during operation.

[0010] In a preferred embodiment, a fixing plate is fixedly installed at the surface edge of the horizontal support leg fixing block, and a hole is opened at the center of the surface of the fixing plate, in which a fastening screw is movably installed.

[0011] By adopting the above technical solution, the outriggers of the engineering vehicle are installed with an overall mounting plate to ensure that the device body does not shift or fall off during the use of the engineering vehicle, thereby improving safety performance.

[0012] In a preferred embodiment, a first reinforcing plate is fixedly installed on the side of the vertical support leg fixing block near the horizontal support leg fixing block, a telescopic rod is fixedly installed on the side of the first reinforcing plate away from the vertical support leg fixing block, a second reinforcing plate is fixedly connected to the end of the telescopic rod, and a second horizontal support leg fixing block is fixedly installed at the end of the second reinforcing plate.

[0013] By adopting the above technical solution, the corners of the outriggers of the engineering vehicle are prone to plastic deformation or breakage. The connection between the first and second reinforcing plates can effectively share the pressure of the corners, improve stress resistance, and reduce the risk of corner breakage.

[0014] In a preferred embodiment, the surface of the branch arm fixing post is movably connected with a fastening bolt.

[0015] By adopting the above technical solution, the fastening bolts are fixed to ensure that the vertical hydraulic rod can be supported stably.

[0016] In a preferred embodiment, a transparent protective plate is fixedly installed on the side of the horizontal support leg fixing block away from the fastening screw, and a transparent movable plate is movably inserted into the side of the transparent protective plate. An installation plug is welded to the surface of the transparent movable plate away from the horizontal support leg fixing block, and an installation slot is opened in the area corresponding to the installation plug on the surface of the second horizontal support leg fixing block near the transparent movable plate.

[0017] By adopting the above technical solution, after the device is installed, the user pulls out the limiting hole and inserts the mounting block into the mounting slot to protect the limiting rod. This prevents the limiting rod from breaking under external force or corroding due to weather conditions.

[0018] In a preferred embodiment, a limiting rod is fixedly installed on the side of the horizontal support leg fixing block, and a limiting hole is formed at the center of the surface of the limiting rod, and a limiting bolt is movably inserted into the surface of the limiting hole.

[0019] By adopting the above technical solution, the user pushes and pulls the second fixing block of the horizontal outrigger to a suitable position, inserts the limiting bolt into the limiting hole, and fixes the length of the horizontal outrigger.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, the commonly used outriggers for process vehicles typically have only one outrigger. During use, this outriggers become unstable on uneven ground, affecting work efficiency. This device, after the branch arm is installed, allows for vertical adjustment of the vertical hydraulic rod to accommodate engineering vehicles of different heights. The chassis can support the weight of the device body. The corners of the outriggers are prone to plastic deformation or breakage. The connection between the first and second reinforcing plates effectively distributes the pressure at the corners, improving stress resistance and reducing the risk of corner breakage.

[0029] Example:

[0030] A type of outrigger for an engineering vehicle includes a horizontal outrigger fixing block 1 with a limit rod fixedly installed on its surface. A second horizontal outrigger fixing block 4 is movably installed at the end of the limit rod. A vertical outrigger fixing block 9 is welded to the lower surface of the second horizontal outrigger fixing block 4. A branch arm mounting plate 5 is fixedly installed at the edge of the vertical outrigger fixing block 9 on the side away from the horizontal outrigger fixing block 1. A hole is opened on the surface of the branch arm mounting plate 5, and a branch arm fixing post 6 is movably installed in the hole. A branch arm 21 is movably installed on the surface of the branch arm fixing post 6. A limit block 20 is fixedly installed at the edge of the surface of the branch arm 21. A vertical hydraulic rod 19 is fixedly installed on the lower surface of the limit block 20. A load-bearing chassis 18 is fixedly installed on the lower surface of the vertical hydraulic rod 19.

[0031] The commonly used outriggers for process vehicles only have one outrigger. When encountering uneven ground during use, the support is unstable, affecting work efficiency. After the branch arm 21 is installed, the vertical hydraulic rod 19 of this device can be adjusted up and down to adapt to engineering vehicles of different heights. The load-bearing chassis 18 can support the weight of the device body.

[0032] Branch arm 21 has a branch arm mounting hole 22 on its surface corresponding to the limiting block 20. The design of the branch arm mounting hole 22 allows the branch arm 21 to be adjusted at any position and angle, and the two branch arms 21 allow the engineering vehicle to maintain a more stable working state during operation.

[0033] A fixing plate 13 is fixedly installed on the edge of the horizontal outrigger fixing block 1. A hole is opened at the center of the surface of the fixing plate 13, and a fastening screw 8 is movably installed in the hole. The installation of the fixing plate 13 on the outrigger of the engineering vehicle ensures that the device body will not shift or fall off during the use of the engineering vehicle, thereby improving safety performance.

[0034] A first reinforcing plate 10 is fixedly installed on the side of the vertical outrigger fixing block 9 closest to the horizontal outrigger fixing block 1. A telescopic rod 11 is fixedly installed on the side of the first reinforcing plate 10 furthest from the vertical outrigger fixing block 9. A second reinforcing plate 12 is fixedly connected to the end of the telescopic rod 11, and a second horizontal outrigger fixing block 4 is fixedly installed at the end of the second reinforcing plate 12. The corners of the outriggers of engineering vehicles are prone to plastic deformation or breakage. The connection between the first reinforcing plate 10 and the second reinforcing plate 12 can effectively distribute the pressure of the corner, improve stress resistance, and reduce the risk of corner breakage.

[0035] The surface of the branch arm fixing column 6 is movably connected to a fastening bolt 7. The fastening bolt 7 is used to fix the vertical hydraulic rod 19 and ensure its stability.

[0036] A transparent protective plate 14 is fixedly installed on the side of the horizontal support leg fixing block 1 away from the fastening screw 8. A transparent movable plate 15 is movably inserted into the side of the transparent protective plate 14. An installation plug 3 is welded to the surface of the transparent movable plate 15 away from the horizontal support leg fixing block 1. An installation slot 17 is opened in the area corresponding to the installation plug 3 on the surface of the second horizontal support leg fixing block 4 near the transparent movable plate 15. After the device is installed, the user pulls out the limiting hole 2 and movably inserts the installation plug 3 into the installation slot 17 to protect the limiting rod. This prevents the limiting rod from breaking under external force or corroding due to weather conditions during long-term use.

[0037] A limiting rod is fixedly installed on the side of the horizontal outrigger fixing block 1. A limiting hole 2 is opened at the center of the surface of the limiting rod, and a limiting bolt 16 is movably inserted into the surface of the limiting hole 2. The user pushes or pulls the second horizontal outrigger fixing block 4 to a suitable position and inserts the limiting bolt 16 into the limiting hole 2 to fix the length of the horizontal outrigger.

[0038] The implementation principle of an embodiment of an engineering vehicle outrigger in this application is as follows:

[0039] Commonly used outriggers for process vehicles have only one outrigger, which becomes unstable when encountering uneven ground, affecting work efficiency. This device, after the branch arm 21 is installed, allows the vertical hydraulic rod 19 to be adjusted up and down to accommodate engineering vehicles of different heights. The load-bearing chassis 18 can support the weight of the device body. The corners of the outriggers are prone to plastic deformation or breakage. The connection between the first reinforcing plate 10 and the second reinforcing plate 12 effectively distributes the pressure at the corners, improves stress resistance, and reduces the risk of corner breakage.

[0040] After the device is installed, the user pulls out the limiting hole (2) and inserts the mounting block (3) into the mounting slot (17) to protect the limiting rod. In the long term, the limiting rod may break under external force or rust due to weather.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
