Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery, and in particular to a correction mechanism for a double-wheel milling cutter holder; specifically, it is a correction push plate with multiple turning points. Background Technology
[0002] The guide plate is an important device used for correction on a twin-wheel milling machine. It is widely used in various situations requiring precise control of the underground trenching direction, such as foundation pit support, dam seepage prevention, and cofferdam construction to form underground continuous walls. Its main function is to adjust the position and angle of the guide plate during the trenching process, so that the twin-wheel milling machine can dig along a predetermined trajectory, thereby ensuring the verticality and accuracy of the excavation.
[0003] Currently, in the design process of the correction push plate, the design of the pivot point is usually inherited, that is, the pivot point of the hydraulic cylinder, connecting rod and push plate is sometimes shared.
[0004] However, this leads to some problems, such as: the pivot point structure is relatively complex, with multiple components such as push plate, connecting parts, and transmission mechanism sharing the pivot point, which increases the difficulty of manufacturing and maintenance and also increases the cost; at the same time, since the correction push plate needs to be frequently rotated and adjusted during the milling process, the components at the pivot point are prone to wear and damage; this not only affects the service life of the correction push plate, but may also lead to increased failures and downtime. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned defects and propose a method that appropriately separates the turning point structure, thereby facilitating the layout of the correction push plate structure and extending its service life.
[0006] To achieve the above objectives, this utility model is implemented as follows:
[0007] A multi-rotation point correction push plate includes a frame, a drive cylinder, a connecting rod, and a push plate body; wherein the connecting rod, the push plate body, and the frame are connected by a first rotation point assembly to form a parallel four-bar linkage mechanism; the drive cylinder is disposed between the frame and the push plate body and is connected by a second rotation point assembly, wherein the second rotation point assembly shares one rotation point at the frame end, and the first rotation point assembly and the second rotation point assembly are independently disposed at the push plate body.
[0008] The multi-rotation-point correction push plate includes at least four first rotation points in its first rotation point assembly. The four rotation point assemblies are arranged in pairs, forming a rectangular four-corner point arrangement on the frame and the push plate body. The first rotation points are used to connect with the connecting rod, thereby forming a parallel four-bar linkage mechanism between the push plate body, the connecting rod, and the frame.
[0009] The multi-rotation point correction push plate includes at least two second rotation points, which are respectively disposed on the frame and the push plate body. The second rotation point disposed on the frame overlaps with one of the first rotation points disposed on the frame, and the second rotation point disposed on the push plate body is disposed in parallel with the first rotation point disposed on the push plate body. This allows the drive cylinder to have an independent rotation point at the push plate body.
[0010] The aforementioned multi-point correction push plate includes a first pivot point and a second pivot point, respectively, comprising a shaft and a bearing. The bearing is embedded in the push plate body or frame, and the shaft passes through the bearing. The shaft is used to achieve pin connection with the drive cylinder or connecting rod.
[0011] The multi-turn-point correction push plate proposed in this utility model has the following advantages:
[0012] 1. Improve correction accuracy
[0013] The multiple pivot points allow for greater flexibility and accuracy in adjusting the correction push plate. By adjusting the positions of different pivot points, fine-tuning of the slotting direction of the twin-wheel milling machine can be achieved, thereby improving the accuracy of correction. This fine-tuning capability is particularly important for projects requiring high-precision excavation, such as the construction of diaphragm walls.
[0014] 2. Enhance adaptability
[0015] In practical applications, excavation conditions and environments are often complex and varied. Setting multiple turning points allows the correction push plate to better adapt to different excavation conditions and environments. For example, when encountering obstacles or changes in soil hardness during excavation, the slotting trajectory of the twin-wheel milling machine can be adjusted by changing the position and angle of different turning points, thereby ensuring smooth excavation.
[0016] 3. Distribute force
[0017] The multiple pivot points also distribute the pressure on the correction push plate under stress, thereby improving its overall stability and durability. During excavation, the correction push plate needs to withstand enormous pressure from the twin-wheel milling machine and the geological formation. If there is only one pivot point, that pivot point will bear all the pressure, easily leading to wear and damage. The multiple pivot points distribute the pressure across different components, reducing the stress on individual components and extending their service life.
[0018] 4. Improve construction efficiency
[0019] By setting multiple pivot points, the milling direction of the twin-wheel milling machine can be quickly adjusted. This not only reduces rework and correction time caused by milling verticality deviations, but also improves construction efficiency. This rapid adjustment capability is especially important during tight construction schedules.
[0020] 5. Easy to maintain and care for
[0021] The multiple pivot points also provide greater convenience for the maintenance and upkeep of the alignment guide plate. When inspecting and replacing worn parts, the condition of each component can be easily accessed and checked by adjusting the positions of different pivot points. This helps to promptly identify and address potential problems, thereby ensuring the continuous and stable operation of the alignment guide plate. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.
[0024] like Figure 1 A multi-rotation point correction push plate includes a frame, a drive cylinder, a connecting rod, and a push plate body; wherein the connecting rod, the push plate body, and the frame are connected by a first rotation point assembly to form a parallel four-bar linkage mechanism; the drive cylinder is disposed between the frame and the push plate body and is connected by a second rotation point assembly, wherein the second rotation point assembly shares one rotation point at the frame end, and the first rotation point assembly and the second rotation point assembly are independently disposed at the push plate body.
[0025] The first pivot component includes at least four pivot points, with each pair of pivot points forming a rectangular four-corner point arrangement on the frame and the push plate body. The first pivot points are used to connect with the connecting rod, thereby forming a parallel four-bar linkage mechanism between the push plate body, the connecting rod, and the frame.
[0026] The second pivot assembly includes at least two second pivots, which are respectively disposed on the frame and the push plate body. The second pivot on the frame overlaps with one of the first pivots disposed on the frame, and the second pivot on the push plate body is disposed in parallel with the first pivot on the push plate body. This allows the drive cylinder to have an independent pivot at the push plate body.
[0027] The first and second pivot points mentioned above each include a pivot shaft and a bearing. The bearing is embedded in the push plate body or frame, and the pivot shaft passes through the bearing. The pivot shaft is used to achieve a pin connection with the drive cylinder or connecting rod.
[0028] In this embodiment, by setting multiple pivot points, the pressure on the correction push plate under stress is distributed, thereby improving its overall stability and durability and preventing jamming. During excavation, the correction push plate needs to withstand enormous pressure from the twin-wheel milling machine and the geological formation. If there is only one pivot point, that pivot point will bear all the pressure, easily leading to wear and damage. Setting multiple pivot points can distribute the pressure to different components, thereby reducing the stress on individual components and extending their service life.
