Technical Field

[0001] This utility model belongs to the field of excavator technology, specifically referring to a large hydraulic chassis mounting workbench for excavators. Background Technology

[0002] The excavator hydraulic chassis is a structure located at the bottom of the excavator where the tracks and various components are installed. During the installation of the excavator hydraulic chassis, workers usually need to fix the excavator hydraulic chassis with fixing equipment before further installation.

[0003] The patent with publication number CN216690271U discloses a workbench for installing hydraulic chassis of excavators. It uses a motor drive and gear meshing to drive a threaded screw, thereby adjusting the height of the first support plate and the second support plate to facilitate the installation operation by the operator. By setting up a compression spring, a movable plate, a movable groove and a fixed plate, the compression spring pushes the movable plate to move in the movable groove, thereby adjusting the length of the second support plate, which facilitates the installation of hydraulic chassis of different specifications.

[0004] However, during prolonged use, the connection between the movable plate and the fixed plate is easily deformed by the pressure of the hydraulic chassis, which affects the adjustment of the length of the second support plate. Moreover, the hydraulic chassis lacks limiters during operation, making it prone to shaking and hindering the installation and operation of the hydraulic chassis. Utility Model Content

[0005] The technical problem this invention aims to solve is that the existing equipment has a simple connection structure that is prone to deformation, affecting its use, and lacks limiting mechanisms, resulting in poor stability.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: A large hydraulic chassis mounting platform for excavators includes a base plate, a lifting support mechanism set on the base plate, and a lifting and limiting mechanism connected to the lifting support mechanism; the lifting and limiting mechanism includes a support plate and a support plate, the support plate is connected to the lifting support mechanism, a movable groove is provided parallel to the top wall of the support plate, a bidirectional screw is rotatably provided in the movable groove, the two ends of the bidirectional screw are threaded to connecting blocks, the support plate is set on the connecting blocks, and a limiting component is provided on the support plate.

[0007] Furthermore, the top wall of the support plate is provided with guide grooves, which are symmetrically arranged on both sides of the movable groove, and the support plate is slidably arranged on the guide grooves.

[0008] Furthermore, one end of the bidirectional lead screw passes through the side wall of the movable groove and is axially connected to a motor, which is fixedly mounted on the side wall of the support plate.

[0009] Furthermore, the limiting component includes an electric push rod and a clamping plate. The electric push rod is symmetrically arranged at both ends of the support plate, and the clamping plate is located at the output end of the electric push rod. The clamping plates on both sides are arranged close to each other.

[0010] Furthermore, the lifting support mechanism includes a hydraulic cylinder and a rod, both of which are mounted on the base plate. The support plate is connected to the output end of the hydraulic cylinder, and a sleeve is provided on the bottom wall of the support plate. The sleeve is movably mounted on the rod.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. By setting support plates and pallets, the hydraulic chassis can be supported. By setting bidirectional screws, the distance between the two sets of pallets can be easily adjusted, thus supporting hydraulic chassis of different sizes. The structure is stable and not easily deformed.

[0013] 2. By setting electric push rods and clamps, the hydraulic chassis can be limited, improving the stability of equipment support and preventing the hydraulic chassis from shaking and affecting the installation work. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, this utility model proposes a large hydraulic chassis mounting platform for excavators, including a base plate 1, a lifting support mechanism 2 mounted on the base plate 1, and a lifting and limiting mechanism 3 connected to the lifting support mechanism 2. The lifting and limiting mechanism 3 includes a support plate 4 and a support plate 5. The support plate 4 is connected to the lifting support mechanism 2. The top wall of the support plate 4 is provided with a movable groove 6 and a guide groove 10 parallel to each other. The guide groove 10 is symmetrically arranged on both sides of the movable groove 6. A double-acting screw 7 is rotatably mounted in the movable groove 6. One end of the double-acting screw 7 passes through the side wall of the movable groove 6 and is axially connected to a motor 11. The motor 11 is fixedly installed on the side wall of the support plate 4. The two ends of the bidirectional lead screw 7 are threadedly connected to the connecting blocks 8. The support plate 5 is set on the connecting blocks 8 and slides on the guide groove 10. The support plate 5 is provided with a limiting component 9. When the motor 11 is started, the bidirectional lead screw 7 is driven to rotate. The bidirectional lead screw 7 drives the connecting blocks 8 to move. The connecting blocks 8 drive the two sets of support plates 5 to adjust the distance, so as to facilitate the installation and use of different models of hydraulic chassis. The hydraulic chassis is placed on the two sets of support plates 5, and the limiting component 9 is adjusted to limit the hydraulic chassis for subsequent parts installation and use.

[0021] like Figure 3 As shown, the limiting component 9 includes an electric push rod 12 and a clamping plate 13. The electric push rod 12 is symmetrically arranged at both ends of the support plate 5, and the clamping plate 13 is located at the output end of the electric push rod 12. The two clamping plates 13 are arranged close to each other. When the electric push rod 12 is activated, the multi-functional clamping plate 13 moves close to the hydraulic chassis and fixes it to prevent displacement during installation, which would affect the installation process.

[0022] like Figure 2 As shown, the lifting support mechanism 2 includes a hydraulic cylinder 14 and a rod 15. Both the hydraulic cylinder 14 and the rod 15 are mounted on the base plate 1. The support plate 4 is connected to the output end of the hydraulic cylinder 14. A sleeve 16 is provided on the bottom wall of the support plate 4. The sleeve 16 is movably mounted on the rod 15. When the hydraulic cylinder 14 is activated, the support plate 4 is pushed to move. The support plate 4 drives the sleeve 16 to move. At the same time, the sleeve 16 is limited by the rod 15, so that the support plate 4 can be raised and lowered stably to adjust the working height for the use of the staff.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
