[0001] The present invention relates to a lifting system that is easy to assemble and disassemble, and can be applied to the opening and closing of various cover plates, including box cover plates, engineering machinery engine hoods, protective covers, etc., belonging to the field of machinery. Background Art

[0002] With economic development and technological advancement, people's requirements for machine operating comfort and safety are getting higher and higher. Traditionally, components such as covers, hoods, and protective covers that rely on manpower to open are now automated and can be opened and closed with one click. Automatic opening and closing requires a lifting system to support it, which is generally achieved by using electric cylinders or hydraulic cylinders as actuators. For aesthetic reasons, the actuators are often located inside the box or hood. However, if the lifting system fails and the electric cylinder or hydraulic cylinder cannot operate, the box cover or hood will not be able to open. At this time, destructive disassembly may be required; or a larger maintenance channel may be reserved on the box, affecting the appearance. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention proposes a lifting system that is easy to disassemble and can be easily disassembled and opened when the lifting cylinder cannot move.

[0004] The present invention is achieved according to the following technical solutions:

[0005] The first aspect of the present invention discloses a lifting system that is easy to assemble and disassemble, comprising:

[0006] lower box;

[0007] An upper cover is mounted on the lower box body via a hinge, and the upper cover is capable of rotating around the hinge;

[0008] The support mounting plate is arranged inside the lower box body, and is provided with two parallel vertical slots and a plurality of mounting holes below the two vertical slots;

[0009] A lifting support is mounted in a mounting hole on the support mounting plate via a detachable component;

[0010] The bottom of the lifting cylinder is hinged to the lifting support, and the top is hinged to the upper cover. The opening and closing of the upper cover is achieved by the extension and contraction of the lifting cylinder.

[0011] In some embodiments, the lifting support is composed of a fixing plate and two parallel ear plates connected in one piece.

[0012] In some embodiments, the distance between the two parallel ear plates is the same as the distance between the two parallel vertical slots on the support mounting plate inside the lower box.

[0013] In some embodiments, the fixing plate is provided with a mounting hole for connecting to the support mounting plate via a detachable component; and the two ear plates are provided with coaxial pin holes for mounting the lifting cylinder.

[0014] In some embodiments, the ear plate is an N-shaped plate, in which the lower angle is a right angle, and the fixed plate is tightly attached to the right angle and fixed to the ear plate; the width of the vertical groove is greater than the thickness of the ear plate, and the height of the vertical groove is less than the dimension from the horizontal right angle surface in the right angle of the ear plate to the upper horizontal top surface.

[0015] In some embodiments, the rear outer side profile of the ear plate located above the rear side of the fixed plate is composed of a horizontal right-angled surface, a rear convex arc surface and a rear inclined surface inclined forward connected in sequence; the upper angle of the ear plate is an arc angle, and the front outer side profile of the ear plate located above the fixed plate is composed of a front concave arc surface and a front vertical surface connected in sequence; the front outer side profile of the ear plate located above the front side of the fixed plate is composed of a front convex arc surface and a front inclined surface inclined backward connected in sequence.

[0016] In some embodiments, the distance between the rear plane of the fixing plate and the front vertical surface of the front arc surface of the ear plate is the same as the thickness of the support mounting plate.

[0017] In some embodiments, a disassembly hole is provided on the side panel of the lower box body at a position opposite to the mounting hole on the lifting support, and a disassembly tool can be inserted into the disassembly hole to disassemble the detachable component on the lifting support.

[0018] In some embodiments, the detachable component is a bolt, a threaded mounting hole is provided downward from the symmetrical center of the two vertical slots, and the lifting support is mounted in the threaded mounting hole on the support mounting plate by a bolt.

[0019] The second aspect of the present invention discloses a method for disassembling and assembling a lifting support:

[0020] Installation process of the lifting base: insert the two parallel ear plates of the lifting support into the vertical slots on the support mounting plate, and fit the rear plane of the lifting support fixing plate to the support mounting plate; keep the horizontal right-angled surface of the ear plate of the lifting support in contact with the lower edge of the vertical slot. During the lifting process, the horizontal right-angled surface of the ear plate is directly compressed to prevent the fixing bolts of the lifting support from being subjected to shear force; the front vertical surface of the ear plate fits the back of the support mounting plate; finally, install the bolts into the threaded holes of the support mounting plate to secure the lifting support;

[0021] Disassembly process of the lifting support: When the upper cover is in the closed state and the lifting cylinder fails to operate, use an extended socket wrench to remove one of the fixing bolts of the lifting support from the disassembly hole on the side panel of the lower box body, and use external force to lift the upper cover on the other side of the upper cover hinge. At this time, the lifting support will disengage from the two vertical slots of the support fixing plate, and the lifting cylinder and the lifting support will be lifted together with the upper cover. The failed lifting cylinder can then be repaired or replaced without damaging the box body or the upper cover.

[0022] Based on the application of the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0023] The present invention can realize that when the lifting system fails, the cover can be quickly opened by removing only one bolt, which is convenient for maintenance. At the same time, no maintenance channel needs to be reserved on the box body, and the appearance is beautiful, especially for boxes with more complex curved shapes, the effect is better.

[0041] like Figure 1As shown, a lifting system that is easy to disassemble and assemble includes a lower box body 1, an upper cover 3, a hinge 2, a lifting cylinder 4 and a lifting support 5. The upper cover 3 is mounted on the lower box body 1 through the hinge 2, and the upper cover 3 can rotate around the hinge 2; a support mounting plate 1-1 is provided inside the lower box body 1, and the lifting support 5 is fixed to the support mounting plate 1-1 through a bolt 6; the lower hinge hole of the lifting cylinder 4 is connected to the lifting support through a bolt, and the upper hinge hole is connected to the upper cover 3. The opening and closing of the upper cover 3 is achieved by the extension and contraction of the lifting cylinder 4.

[0042] like Figure 2 As shown, two parallel vertical grooves 1-2 are provided on the support mounting plate 1-1, and threaded mounting holes 1-3 are provided at the downward position of the symmetrical centers of the two vertical grooves 1-2; the lifting support 5 is installed in the threaded mounting hole 1-3 by a bolt 6; a disassembly hole 1-4 is provided on the side panel of the lower box body 1 at a position opposite to the threaded mounting hole 1-3 on the support support plate 1-1, and the fixing bolt 6 of the lifting support 5 can be removed through the disassembly hole 1-4.

[0043] like Figure 3 、 Figure 4 As shown, the lifting support 5 is composed of two parallel ear plates 5-1 and a fixed plate 5-2 welded together, and a mounting hole 5-4 is provided on the fixed plate 5-2; the spacing between the two parallel ear plates 5-1 of the lifting support 5 is the same as the spacing between the two parallel vertical grooves 1-2 on the support mounting plate 1-1 inside the lower box body 1; and coaxial pin holes 5-3 are provided on the two ear plates 5-1 for mounting the lifting cylinder 4.

[0044] The width of the vertical groove 1-2 exceeds the thickness of the ear plate 5-1; the height of the vertical groove 1-2 is less than the dimension M from the horizontal right-angle surface 5-9 to the top surface 5-5 of the ear plate 5-1.

[0045] The front and rear sides of the ear plate 5-1 of the lifting support 5 are both arc structures (the concave front arc surface 5-7 and the convex rear arc surface 5-8) to prevent it from being stuck by the upper and lower sides of the vertical groove 1-2 during the disassembly process.

[0046] The distance between the rear plane 5-10 of the fixing plate 5-2 of the lifting support 5 and the front vertical surface 5-6 of the ear plate 5-1 is N, and N is the same as the thickness of the support mounting plate 1-1.

[0047] Figure 5 、 Figure 6 and Figure 7 As shown, the installation process of the lifting support 5:

[0048] First follow Figure 4In the direction of A, insert the two parallel ear plates 5-1 of the lifting support 5 into the vertical groove 1-2 on the support mounting plate 1-1, and then in the direction of B, fit the rear plane 5-10 of the fixing plate 5-2 of the lifting support 5 with the support mounting plate 1-1; the horizontal right-angled surface 5-9 of the lifting support 5 is kept in contact with the lower edge of the vertical groove 1-2, so as to ensure that the horizontal right-angled surface 5-9 is directly compressed during the lifting process, and the fixing bolt 6 of the lifting support 5 is prevented from being subjected to shear force; the front vertical surface 5-6 of the ear plate 5-1 is fit with the back side of the support mounting plate 1-1; finally, install the bolt 6 in the threaded hole 1-3 of the support mounting plate 1-1 to firmly fix the lifting support 5.

[0049] Figure 8 、 Figure 9 、 Figure 10 As shown in the figure, the disassembly process of the lifting support:

[0050] When the upper cover 3 is in the closed state and the lifting cylinder 4 fails to operate, an extended socket wrench 7 can be used to remove a fixing bolt 6 of the lifting support 5 from the disassembly hole 1-4 on the side panel of the lower box body 1, and an external force can be used to lift the upper cover 3 on the other side of the upper cover hinge. At this time, the lifting support 5 will disengage from the two vertical slots 1-2 of the support fixing plate 1-1, and the lifting cylinder 1-1 and the lifting support 5 will be lifted together with the upper cover 3. The failed lifting cylinder 4 can then be repaired or replaced without destroying the box body.

[0051] The present invention can realize that when the lifting system fails, only one bolt needs to be removed to realize the rapid opening of the cover plate, thereby facilitating maintenance. At the same time, no maintenance passage needs to be reserved on the box body, and the appearance is beautiful.
