Description

Technical Field

[0001] This utility model relates to the field of engine equipment maintenance technology, and in particular to a protective mechanism and an inspection door for the lower engine frame. Background Technology

[0002] In the existing technology, the engine lower frame is usually equipped with an access door. The upper layer of the engine lower frame is equipped with a mechanical air damper, a push oil tank and its associated automated components, while the lower layer of the engine lower frame is equipped with a high-pressure oil pump, an oil mist absorption device, a cooler and its automated components. The access door is mainly used to allow personnel to access the electrical equipment arrangement in the lower layer of the engine lower frame from the upper layer of the engine lower frame, so as to facilitate equipment maintenance and repair work.

[0003] Traditional maintenance doors use a protective mechanism at the bottom, while the transmission-type protective mechanism uses a fixed cover plate, some of which use a single hinge design. The main problems are low opening or closing efficiency and inconvenience in operation, especially in emergency situations where it is necessary to quickly access the lower level of equipment on the lower rack, resulting in low work efficiency and longer time required. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the inconvenience of operation in the above-mentioned or existing technologies, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a protective mechanism.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cover opening component, which includes a fixing member, a support plate disposed above the fixing member, a rotating shaft disposed inside the support plate, a cover plate disposed above the fixing member, and an entry hole disposed below the fixing member; and a folding component, which includes a connecting component disposed on one side of the cover plate and a movable component disposed on one side of the connecting component.

[0008] As a preferred embodiment of the protective mechanism of this utility model, the fixing component includes a mounting base disposed above the entry hole and a fixing bolt disposed above the mounting base.

[0009] As a preferred embodiment of the protective mechanism of this utility model, the cover plate includes a right folding plate disposed above the mounting base, a left folding plate disposed on one side of the right folding plate, and a folding shaft disposed between the right folding plate and the left folding plate.

[0010] As a preferred embodiment of the protective mechanism of this utility model, the connecting component includes a connecting plate disposed on one side of the right folding plate and a rotating plate disposed on one side of the left folding plate.

[0011] As a preferred embodiment of the protective mechanism of this utility model, the movable component includes a rotating rod one disposed on one side of the connecting plate, a rotating top rod two disposed on one side of the rotating plate, and a connecting seat disposed on one side of the rotating rod one; wherein, one end of the connecting seat is rotatably connected to the rotating rod two.

[0012] As a preferred embodiment of the protective mechanism of this utility model, the right folding plate is provided with a handle, and the outer surface of the handle is provided with anti-slip texture.

[0013] As a preferred embodiment of the protective mechanism of this utility model, a baffle is provided between the mounting base and the cover plate.

[0014] As a preferred embodiment of the protective mechanism of this utility model, the material of the rotating shaft must be a wear-resistant and corrosion-resistant material.

[0015] The beneficial effects of this protective mechanism are as follows: This invention enables the cover to be opened and closed quickly with a simple lifting action, greatly improving operational efficiency. The design of the left and right folding plates makes the cover occupy little space after opening, making it suitable for use in confined spaces. When the left and right folding plates are unfolded, they form a stable support with the ground, preventing the cover from closing accidentally. The use of fixing bolts can prevent unauthorized operation and increase safety. By adjusting the angle and length of the left and right folding plates, this invention can adapt to manholes of different sizes and shapes, and has strong versatility.

[0016] In view of the problem that the cover may be accidentally opened by human touch during actual use, an engine underframe maintenance door is proposed, wherein: a locking device is provided below the cover.

[0017] As a preferred embodiment of the engine underframe maintenance door of this utility model, the locking component includes a strong electromagnet one disposed below the cover plate, a strong electromagnet two disposed above the baffle plate, and a control switch disposed on the baffle plate.

[0018] The beneficial effects of the engine underframe maintenance door of this utility model are as follows: Due to the frictional self-locking of the handle, force is required in the first stage, and it will not be moved randomly. When the first part is pulled, the first and second strong electromagnets are de-energized, thereby releasing the lock between the cover and the baffle. The above design can prevent accidental opening of the cover. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-2This is the first embodiment of the present invention. This embodiment provides a protective mechanism, including a cover opening component 100, which includes a fixing member 101, a support plate 102 disposed above the fixing member 101, a rotating shaft 103 disposed inside the support plate 102, a cover plate 104 disposed above the fixing member 101, and an entry hole 105 disposed below the fixing member 101; and a folding component 200, which includes a connecting component 201 disposed on one side of the cover plate 104, and a movable component 202 disposed on one side of the connecting component 201.

[0030] The support plate 102 is fixed in position by the fastener 101. There are two support plates 102, which are symmetrically arranged relative to the center of the fastener 101. The rotating shaft 103 is connected to the rotating shaft 103 of the support plate 102. The support plate 102 is used to support the rotating shaft 103. The cover plate 104 drives the rotating shaft 103 to rotate. The cover plate 104 is fixedly connected to the rotating shaft 103. The support plate 102 is fixedly connected to the fastener 101. The movable component 202 is connected to the connecting component 201. The folding component 200 divides the cover plate 104 into two parts and allows the cover plate 104 to be folded. Through the cooperation between the above components, the position of the manhole 105 can be protected. The design of the folding component 200 makes the cover plate 104 occupy little space after opening, which is suitable for use in narrow spaces.

[0031] Furthermore, the fastener 101 includes a mounting base 101a located above the inlet hole 105 and a fixing bolt 101b located above the mounting base 101a. The mounting base 101a is fixed to an appropriate position on the lower frame of the engine by pre-embedded bolts or welding. Its structure is stable and can withstand a large weight and external force, ensuring the safety and reliability of the cover plate 104 during use. The fixing bolt 101b is used to fix the position of the mounting base 101a so that it can be stably set on the inlet hole 105.

[0032] Furthermore, the cover plate 104 includes a right folding plate 104a disposed above the mounting base 101a, a left folding plate 104b disposed on one side of the right folding plate 104a, and a folding shaft 104c disposed between the right folding plate 104a and the left folding plate 104b. The folding shaft 104c is located at the connection between the left and right folding plates 104a, allowing the left and right folding plates 104a to unfold outward and automatically position themselves to adapt to different opening angles. The left and right folding plates 104a are connected to each other through the folding shaft 104c and can be folded relative to the baffle 301. Folding can reduce the space occupied, so as not to interfere with the staff entering the access hole 105.

[0033] Furthermore, the connecting assembly 201 includes a connecting plate 201a disposed on one side of the right folding plate 104a and a rotating plate 201b disposed on one side of the left folding plate 104b. The connecting plate 201a is fixedly connected to the right folding plate 104a, and the rotating plate 201b is fixedly connected to the left folding plate 104b. The connecting plate 201a and the rotating plate 201b are connected to the movable assembly 202.

[0034] Furthermore, the movable component 202 includes a first rotating rod 202a disposed on one side of the connecting plate 201a, a second rotating rod 202c disposed on one side of the rotating plate 201b, and a connecting seat 202b disposed on one side of the first rotating rod 202a; wherein, one end of the connecting seat 202b is rotatably connected to the second rotating rod 202c, the first rotating rod 202a is rotatably connected to the connecting plate 201a, the second rotating rod 202c is rotatably connected to the rotating plate 201b, the connecting seat 202b is fixedly connected to the first rotating rod 202a, and the second rotating rod 202c is rotatably connected to the connecting seat 202b.

[0035] Furthermore, a handle 300 is provided on the right folding plate 104a, and an anti-slip texture 301 is provided on the outer surface of the handle 300. The handle 300 is located on the outside of the right folding plate 104a, making it easy for the operator to grip and apply force, making it simple and effortless to open and close the cover 104. The anti-slip texture 301 is provided to prevent slippage when lifting the right folding plate 104a.

[0036] Operation process: With the cover closed, the mounting base 101a is fixed directly above the inlet hole 105. Through the cooperation between the connecting plate 201a, the rotating plate 201b, the rotating rod 1 202a, the rotating rod 2 202c and the connecting base 202b, the right folding plate 104a and the left folding plate 104b can be folded together. The design of the folding shaft 104c allows the folding plates to be folded to any required angle.

[0037] Example 2

[0038] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, a baffle 301 is provided between the mounting base 101a and the cover plate 104. The baffle 301 is designed around the mounting base 101a and connected to it via a rotating shaft 103, allowing it to rotate around the shaft. The baffle 301's placement around the perimeter prevents foreign objects from falling underneath. One end of the baffle 301 is connected to the rotating shaft 103, allowing it to rotate around the shaft to open and close the cover plate 104. The dimensions and thickness of the baffle 301 are designed according to the actual size of the manhole to ensure complete coverage.

[0039] Specifically, the material of the rotating shaft 103 must be wear-resistant and corrosion-resistant. The rotating shaft 103 is a key component connecting the baffle 301 and the mounting base 101a, allowing the baffle 301 to rotate around it. The material of the rotating shaft 103 must be wear-resistant and corrosion-resistant to ensure long-term reliability.

[0040] The rest of the structure is the same as in Example 1.

[0041] Example 3

[0042] Reference Figures 1-5 This is the third embodiment of the present utility model. Unlike the previous embodiment, this embodiment provides an engine lower frame maintenance door, and a locking member 400 is provided below the cover plate 104. The locking member 400 is designed to prevent the cover from being opened accidentally when it is not necessary to open the cover.

[0043] Specifically, the locking component 400 includes a strong electromagnet 401 located below the cover plate 104, a strong electromagnet 402 located above the baffle 301, and a control switch 403 located inside the handle 300. The magnetic poles of the strong electromagnet 401 and the strong electromagnet 402 are opposite when energized, and no magnetic poles are displayed when not energized. The handle 300 is designed in two parts. One part is de-energized when pulled. Due to the self-locking friction on the handle 300, force is required in the first stage, and there will be no random movement. When the first part is pulled, the strong electromagnets 401 and 402 are de-energized, thereby releasing the lock between the cover plate 104 and the baffle 301.

[0044] The remaining structures are the same as those in Example 1 or 2.
