Description

Technical Field

[0001] This invention belongs to the field of large cabin equipment opening mechanisms, and more specifically, relates to an opening mechanism with adaptive function. Background Technology

[0002] In various fields of large-scale cabin equipment, hatch opening mechanisms have wide applications. As a driving mechanism, it can drive the hatch to open or close, thereby ensuring that the hatch meets usage requirements.

[0003] Patent searches revealed that existing cover opening mechanisms are basically fixed mechanical connections with almost no adjustable margin, resulting in relatively large dimensional errors in the processing and assembly of large cabins. In particular, when large cabins have high requirements for sealing, cover opening mechanisms without adaptive functions are difficult to meet the requirements, and can easily lead to a decline in the overall sealing performance of the cabin under different complex working conditions.

[0004] Accordingly, there is an urgent need for further improvements in this area to better meet the hatch opening and closing requirements of large cabin equipment under various complex operating conditions. Summary of the Invention

[0005] In view of the above-mentioned defects or needs of the prior art, the purpose of this invention is to provide a cover opening mechanism with adaptive function. By fully combining the usage characteristics and needs of large cabin equipment under various complex working conditions, the specific structural composition and setting method of the cover opening mechanism are improved in a targeted manner. Accordingly, it can provide good adaptive function, efficiently and reliably drive the cover to realize the opening and closing operation, and at the same time has the characteristics of compact structure, easy operation, and good adaptability.

[0006] To achieve the above objectives, according to the present invention, an adaptive hatch opening mechanism is provided for opening and closing hatches of various types of hulls. The mechanism is characterized in that it is integrally connected and arranged on one side of the hull, and includes an opening cylinder, a main frame, an upper support, a floating locking pin, and a tilting support arm, wherein:

[0007] The main frame serves as the vertical main frame of the entire opening mechanism, on which other components are installed, and its bottom is connected to the transport vehicle body, thereby transferring the load to the transport vehicle body.

[0008] The cover-opening cylinder is vertically positioned on the side of the main frame and is used to provide the power to open the cover.

[0009] The upper support is located on the top of the main frame and is flexibly connected to the tilting arm located above it via its own piston.

[0010] The tilting arm is located on the upper side of the upper support. Its inner side is connected to the cabin body, its outer side is connected to the opening cylinder through the arm pin and transmits power, and its bottom cooperates with the floating locking pin to perform the rotation function.

[0011] The floating locking pin includes a locking pin shaft and a locking pin drive cylinder. When the hatch is closed, both the opening cylinder and the locking pin shaft of the floating locking pin are in the retracted state. At this time, the tilting support arm is not mechanically connected to the floating locking pin, allowing the hatch to close naturally in an adaptive manner. When the hatch is opened, both the opening cylinder and the locking pin shaft of the floating locking pin are in the extended state. At this time, the tilting support arm and the floating locking pin are mechanically connected and cooperate, allowing the hatch to tilt and open.

[0012] More preferably, the main frame is welded from aluminum plates and then machined to meet dimensional requirements.

[0013] More preferably, the bottom of the main frame is connected to the transport vehicle body by bolts.

[0014] More preferably, the upper support is welded from steel plates and then machined to meet dimensional requirements.

[0015] More preferably, the upper support has multiple insertion holes for respectively accommodating locking pins for mounting the flip arm and the floating locking pin.

[0016] More preferably, the tilting arm is welded from aluminum plate and then machined to meet dimensional requirements.

[0017] More preferably, the inner side of the tilting arm is connected to the cabin body by bolts.

[0018] More preferably, each component of the opening mechanism described above is a modular structure.

[0019] In summary, compared with the prior art, the above-described technical solutions conceived by this invention mainly possess the following technical advantages:

[0020] 1. This invention fully combines the usage characteristics and requirements of large cabin equipment under various complex working conditions, and makes targeted improvements to the specific structure and configuration of its hatch opening mechanism. Accordingly, it can smoothly realize the opening and closing of the hatch in a compact and easy-to-operate manner. In particular, it can provide good adaptive function and effectively overcome the shortcomings of existing similar products.

[0021] 2. By setting a floating locking pin, the present invention only needs to insert the locking pin during the movement of the hatch during the entire operation. After closing in place, the pin retracts. This method can avoid the hatch being affected by force and thus allow the hatch to close naturally, thereby achieving the self-adaptive function efficiently and reliably.

[0022] 3. The opening mechanism of the present invention has a slender structure, which is compact, easy to operate, and occupies little space. At the same time, by using a hydraulic cylinder for driving, the hydraulic oil can achieve self-lubrication of the hydraulic cylinder, thus having the advantages of maintenance-free and high reliability.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Figure 1 This is a three-dimensional structural view of the lid-opening mechanism with adaptive function according to the present invention. Figure 2 This is a structural cross-sectional view of the lid-opening mechanism with adaptive function according to the present invention. (See figure) Figure 1 and Figure 2 As shown, the cover opening mechanism according to the present invention mainly includes a cover opening cylinder 1a, a main frame 1b, an upper support 1c, a floating locking pin 1d, and a flipping support arm 1e, etc., which will be explained in detail below.

[0031] See Figure 1 and Figure 2 The main frame 1b serves as the vertical main frame of the entire opening mechanism, on which other components are mounted, and its bottom is connected to the transport vehicle body to transfer the load to the transport vehicle body; the opening cylinder 1a is arranged vertically on the side of the main frame 1b and is used to provide opening power; the upper support 1c is arranged on the top of the main frame 1b and is flexibly connected to the tilting arm 1e located above it through its own piston.

[0032] The tilting support arm 1e is located on the upper side of the upper support 1c. Its inner side is connected to the cabin 2, and its outer side is connected to the opening cylinder 1a via a support arm pin to transmit power. Its bottom cooperates with the floating locking pin 1d to perform a rotation function. In addition, the floating locking pin 1d includes a locking pin shaft and a locking pin drive cylinder. When the cabin 2 is closed, the opening cylinder 1a and the locking pin shaft of the floating locking pin 1d are both in the retracted state. At this time, the tilting support arm 1e and the floating locking pin 1d are not mechanically connected, so that the cabin cover closes naturally in an adaptive manner. When the cabin 2 is opened, the opening cylinder 1a and the locking pin shaft of the floating locking pin 1d are both in the extended state. At this time, the tilting support arm 1e and the floating locking pin 1d are mechanically connected and cooperate, so that the cabin cover tilts open.

[0033] Let's combine them again below. Figure 1 and Figure 2 This will provide a more detailed explanation of each of the above components.

[0034] The cover-opening cylinder 1a serves as the driving part of the cover-opening mechanism 1, providing power to the cover-opening mechanism 1. When the cover-opening cylinder is in the extended state, the cabin is in the closed state; when the cover-opening cylinder is in the retracted state, the cabin is in the open state.

[0035] The main frame 1b is preferably made of aluminum plate welded together and then machined to meet the size requirements. It serves as the main frame of the cover opening mechanism 1 and provides an installation interface for other components. Its bottom can be connected to the vehicle body by bolts, thereby transferring the load to the vehicle body.

[0036] The upper support 1c is preferably welded from steel plates and then machined to meet dimensional requirements. On the one hand, the upper support 1c is flexibly connected to the tilting arm 1e through its own piston; on the other hand, it can also provide insertion holes for the tilting arm 1e and the floating locking pin 1d.

[0037] The floating locking pin 1d includes a locking pin shaft and a locking pin drive cylinder. When the hatch is closed, the floating locking pin 1d is in the retracted state. At this time, the slewing shaft of the tilting arm 1e has no mechanical connection and is in a natural state, which can ensure that the hatch is in a natural state and ensure the sealing effect. When the hatch needs to be opened or closed, the floating locking pin 1d extends and is inserted into the locking pin hole of the tilting arm 1e to achieve hole-shaft engagement. The locking pin shaft acts as a slewing bearing and is subjected to the load during the opening or closing of the hatch.

[0038] In addition, the tilting arm 1e is preferably made of aluminum plate by welding, which has the advantages of light weight and high strength. After welding, it is machined to meet the size requirements. The inner side of the tilting arm 1e is connected to the cabin 2 by bolts; the outer side is used to connect with the cover opening cylinder 1a by a pin to transmit power; the bottom cooperates with the floating locking pin to realize the rotation function.

[0039] The following will combine Figure 3 and Figure 4 This will explain in detail the working process and operating mechanism of the present invention.

[0040] In actual operation, the floating locking pin is inserted only during the opening and closing of the hatch, and retracts after the hatch is closed. This prevents the hatch from being subjected to force that affects the seal, allowing the hatch to close naturally and preventing the hatch from bearing load that affects the cabin seal, thereby achieving the self-adaptability of the opening mechanism.

[0041] In summary, compared with existing devices, the hatch opening mechanism of the present invention has a compact overall structure, high reliability, easy installation and use, and strong environmental adaptability. It can not only smoothly realize the opening and closing operation of the hatch, but also provide good self-adaptive function, effectively overcoming the shortcomings of existing similar products. Therefore, it is particularly suitable for hatch opening or closing applications of large cabin equipment in various complex working conditions.

[0042] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
