Description

Technical Field

[0001] This invention relates to the field of safety ladder cage technology, and specifically to a movable, adjustable, multifunctional safety ladder cage. Background Technology

[0002] Traditional safety measures for working at heights and navigating passage at docks rely solely on safety nets, ropes, and temporary ladders. These methods have a low safety factor, and safety nets and ropes have short lifespans and are easily worn out. They also offer limited points of leverage, making it difficult for workers to operate. While temporary ladders offer some improvement in safety and are less prone to damage, they only provide a fixed temporary passage. For large-scale construction at the dock, this is insufficient, requiring numerous temporary ladders or the use of cranes to reposition them. Furthermore, these temporary ladders are typically prefabricated in factories with fixed dimensions such as ladder length and step angles, limiting their use to fixed spaces, angles, and distances.

[0003] For example, Chinese patent CN108783928A discloses a mobile ladder for book management, including a storage cart, a ladder mechanism, and a book box, which can realize the up and down movement of the storage mechanism and the overall horizontal movement, improving the efficiency, convenience and safety of book sorting for staff.

[0004] For example, Chinese patent CN105133858A discloses an adjustable safety construction ladder, which belongs to the field of construction ladders in the unloading industry. It includes a counterweight box, a fixed cantilever column, a cantilever top pin, a movable ladder positioner, a movable cantilever column, a cantilever beam, a safety belt suspension ring, etc. It can achieve different height and angle adjustments, which can ensure the personal safety of construction personnel working at height. It uses detachable parts, making it convenient and quick to install, transport, and use.

[0005] Furthermore, the aforementioned ladders can only be used in construction environments such as moving from low to high, going straight up and down, going diagonally up and down, and moving horizontally; they cannot be used in environments such as crossing obstacles or moving in space.

[0006] Based on this, the present invention designs a movable, adjustable, multifunctional safety ladder cage to solve the above problems. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mobile, adjustable, multifunctional safety cage.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A mobile, adjustable, multi-functional safety cage includes a first support component, a second support component, a fixed triangular component, a deformable triangular component, an upper hydraulic telescopic rod, a first universal joint assembly, a second universal joint assembly, and a support component;

[0010] The fixed triangular components are provided in multiple sets. The lower sides of adjacent fixed triangular components are mounted on a set of first universal joint components, and the upper sides of the fixed triangular components are symmetrically mounted with second universal joint components. An upper hydraulic telescopic rod is installed between the second universal joint components of adjacent fixed triangular components. The lower sides of the fixed triangular components at the ends and the first support components are mounted on a set of first universal joint components. An upper hydraulic telescopic rod is fixedly mounted on the upper side of the first support component, and the output end of the upper hydraulic telescopic rod is connected to the second universal joint component.

[0011] The deformable triangular components are provided in multiple sets. The lower sides of adjacent deformable triangular components are mounted on a set of first universal joint components, and the upper sides of the deformable triangular components are symmetrically mounted with second universal joint components. An upper hydraulic telescopic rod is installed between the second universal joint components of adjacent deformable triangular components. The lower sides of the deformable triangular components at the ends and the first support components are mounted on a set of first universal joint components. An upper hydraulic telescopic rod is fixedly mounted on the upper side of the first support component, and the output end of the upper hydraulic telescopic rod is connected to the second universal joint component.

[0012] Casters are fixedly installed on the outer bottom of the first and second support members.

[0013] Furthermore, the fixed triangular member includes side struts and lower struts. There are two side struts, and the lower ends of the two side struts are symmetrically fixed at both ends of the lower strut.

[0014] Furthermore, the fixed triangular member also includes a first mounting block, on which the upper ends of the two side support rods are fixedly mounted.

[0015] Furthermore, the deformable triangular component includes a side hydraulic telescopic rod and a lower hydraulic telescopic rod, with two side hydraulic telescopic rods provided; the lower end of one side hydraulic telescopic rod is fixedly installed on the lower hydraulic telescopic rod, and the lower end of the other side hydraulic telescopic rod is fixedly installed on the output end of the lower hydraulic telescopic rod.

[0016] Furthermore, the deformable triangular member also includes a second mounting block, with the output ends of the two side hydraulic telescopic rods fixedly mounted on the lower side of the second mounting block.

[0017] Furthermore, the first universal joint assembly consists of two nested rings; one ring of the first universal joint assembly is fixedly installed at the connection of a set of side struts and bottom struts, and the other ring of the first universal joint assembly is fixedly installed at the connection of adjacent side struts and bottom struts.

[0018] Furthermore, the second universal joint assembly has the same structure as the first universal joint assembly; a ring of a second universal joint assembly is installed at the end of the upper hydraulic telescopic rod, and another ring of the second universal joint assembly is fixedly installed on the first mounting block; a ring of another second universal joint assembly is fixedly installed at the output end of the upper hydraulic telescopic rod, and another ring of the other second universal joint assembly is fixedly installed on the adjacent first mounting block.

[0019] Furthermore, the support assembly includes fixed rods and telescopic rods. Multiple fixed rods are evenly and uniformly fixedly installed on the lower side of the first support member and the second support member. Multiple fixed rods are evenly and uniformly fixedly installed on the lower support rod and the lower hydraulic telescopic rod. One end of the telescopic rod is hinged to the lower support rod, and the other end of the telescopic rod is hinged to the output end of the lower hydraulic telescopic rod.

[0020] Compared with the prior art, the beneficial effects of this invention are as follows: 1. In the initial state, the upper hydraulic telescopic rods on the fixed triangular member are collinear, and the upper hydraulic telescopic rods on the deformable triangular member are collinear; the upper hydraulic telescopic rods on the fixed triangular member and the deformable triangular member are stretched as a whole, thereby under the limiting action of the fixed triangular member, the deformable triangular member, the first universal joint connecting assembly and the second universal joint connecting assembly, the adjacent fixed triangular member is flipped downward, and the adjacent deformable triangular member is flipped downward, thereby causing the support assembly between the fixed triangular member, the deformable triangular member and the first support member and the second support member to arch upward;

[0021] 2. The upper hydraulic telescopic rods on the fixed triangular member and the deformable triangular member are compressed as a whole, thereby causing the adjacent fixed triangular member to flip upward and the adjacent deformable triangular member to flip upward under the limiting action of the fixed triangular member, the deformable triangular member, the first universal joint assembly and the second universal joint assembly, so that the support assembly between the fixed triangular member, the deformable triangular member and the first support member and the second support member is recessed downward.

[0022] 3. Operate the upper hydraulic telescopic rod on the deformable triangular component and the deformable triangular component to make the deformable triangular component larger as a whole. The upper hydraulic telescopic rod is stretched accordingly. Thus, under the limiting action of the fixed triangular component, the first universal joint assembly, the second universal joint assembly and the support assembly, the support assembly between the fixed triangular component, the deformable triangular component and the first support assembly and the second support assembly rotates to one side of the fixed triangular component.

[0023] 4. Operate the upper hydraulic telescopic rod on the deformable triangular component and the deformable triangular component to reduce the overall size of the deformable triangular component. The upper hydraulic telescopic rod is compressed accordingly. Under the limiting action of the fixed triangular component, the first universal joint assembly, the second universal joint assembly and the support assembly, the support assembly between the fixed triangular component, the deformable triangular component and the first support component and the second support component rotates to one side of the deformable triangular component.

[0033] 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0035] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A mobile adjustable multi-functional safety cage includes a first support member 11, a second support member 12, a fixed triangular member 2, a deformable triangular member 3, an upper hydraulic telescopic rod 4, a first universal joint assembly 51, a second universal joint assembly 52, and a support assembly 6.

[0036] The fixed triangular member 2 is provided in multiple sets. The lower side of the adjacent fixed triangular member 2 is installed on a set of first universal joint components 51, and the upper side of the fixed triangular member 2 is symmetrically installed with second universal joint components 52. An upper hydraulic telescopic rod 4 is installed between the second universal joint components 52 of the adjacent fixed triangular member 2. The lower side of the fixed triangular member 2 at the end and the first support member 11 is installed on a set of first universal joint components 51. An upper hydraulic telescopic rod 4 is fixedly installed on the upper side of the first support member 11, and the output end of the upper hydraulic telescopic rod 4 is connected to the second universal joint component 52.

[0037] The deformable triangular member 3 is provided in multiple sets. The lower side of adjacent deformable triangular members 3 is installed on a set of first universal joint components 51, and the upper side of the deformable triangular member 3 is symmetrically installed with second universal joint components 52. An upper hydraulic telescopic rod 4 is installed between the second universal joint components 52 of adjacent deformable triangular members 3. The lower side of the deformable triangular member 3 at the end and the first support member 11 is installed on a set of first universal joint components 51. An upper hydraulic telescopic rod 4 is fixedly installed on the upper side of the first support member 11, and the output end of the upper hydraulic telescopic rod 4 is connected to the second universal joint component 52.

[0038] Universal wheels 7 are fixedly installed on the outer bottom of the first support member 11 and the second support member 12.

[0039] In this embodiment, when the movable adjustable multi-functional safety cage is working normally, in the initial state, the upper hydraulic telescopic rods 4 on the fixed triangular member 2 are collinear, and the upper hydraulic telescopic rods 4 on the deformable triangular member 3 are collinear; the upper hydraulic telescopic rods 4 on the fixed triangular member 2 and the deformable triangular member 3 are stretched as a whole, thereby under the limiting action of the fixed triangular member 2, the deformable triangular member 3, the first universal joint assembly 51 and the second universal joint assembly 52, the adjacent fixed triangular member 2 is flipped downward, and the adjacent deformable triangular member 3 is flipped downward, thereby causing the support assembly 6 between the fixed triangular member 2, the deformable triangular member 3 and the first support member 11 and the second support member 12 to arch upward;

[0040] The upper hydraulic telescopic rod 4 on the fixed triangular member 2 and the deformable triangular member 3 is compressed as a whole. Under the limiting action of the fixed triangular member 2, the deformable triangular member 3, the first universal joint assembly 51 and the second universal joint assembly 52, the adjacent fixed triangular member 2 is flipped upward and the adjacent deformable triangular member 3 is flipped upward, so that the support assembly 6 between the fixed triangular member 2, the deformable triangular member 3 and the first support member 11 and the second support member 12 is recessed downward.

[0041] The upper hydraulic telescopic rod 4 on the deformable triangular member 3 and the deformable triangular member 3 are operated to make the deformable triangular member 3 larger as a whole, and the upper hydraulic telescopic rod 4 is stretched accordingly. Thus, under the limiting action of the fixed triangular member 2, the first universal joint assembly 51, the second universal joint assembly 52 and the support assembly 6, the support assembly 6 between the fixed triangular member 2, the deformable triangular member 3 and the first support assembly 11 and the second support assembly 12 rotates to one side of the fixed triangular member 2.

[0042] The upper hydraulic telescopic rod 4 on the deformable triangular member 3 and the deformable triangular member 3 are operated to reduce the overall size of the deformable triangular member 3 and compress the upper hydraulic telescopic rod 4 accordingly. Thus, under the limiting action of the fixed triangular member 2, the first universal joint assembly 51, the second universal joint assembly 52 and the support assembly 6, the support assembly 6 between the fixed triangular member 2, the deformable triangular member 3 and the first support assembly 11 and the second support assembly 12 rotates to one side of the deformable triangular member 3.

[0043] The two ends of the first support member 11 and the second support member 12 are installed in the guide grooves in the area to be connected, so as to support and fix the two ends, and the casters 7 facilitate the overall movement.

[0044] The bending deformation in four directions (up, down, left, and right) is achieved through the above method, thus making it applicable to various working conditions.

[0045] Example 2: In some embodiments, such as Figures 1-6As shown, in a preferred embodiment of the present invention, the fixed triangular member 2 includes a side support rod 21 and a lower support rod 22. There are two side support rods 21, and the lower ends of the two side support rods 21 are symmetrically fixedly installed at both ends of the lower support rod 22.

[0046] The fixed triangular member 2 also includes a first mounting block 23, and the upper ends of the two side support rods 21 are fixedly mounted on the first mounting block 23;

[0047] The deformable triangular member 3 includes a side hydraulic telescopic rod 31 and a lower hydraulic telescopic rod 32. There are two side hydraulic telescopic rods 31; the lower end of one side hydraulic telescopic rod 31 is fixedly installed on the lower hydraulic telescopic rod 32, and the lower end of the other side hydraulic telescopic rod 31 is fixedly installed on the output end of the lower hydraulic telescopic rod 32.

[0048] The deformable triangular member 3 also includes a second mounting block 33, and the output ends of the two side hydraulic telescopic rods 31 are fixedly installed on the lower side of the second mounting block 33;

[0049] The first universal joint assembly 51 is composed of two nested rings; one ring of the first universal joint assembly 51 is fixedly installed at the connection of a set of side support rods 21 and lower support rods 22, and the other ring of the first universal joint assembly 51 is fixedly installed at the connection of adjacent side support rods 21 and lower support rods 22.

[0050] The second universal joint assembly 52 has the same structure as the first universal joint assembly 51; a ring of the second universal joint assembly 52 is installed at the end of the upper hydraulic telescopic rod 4, and the other ring of the second universal joint assembly 52 is fixedly installed on the first mounting block 23; a ring of another set of second universal joint assemblies 52 is fixedly installed at the output end of the upper hydraulic telescopic rod 4, and the other ring of the other set of second universal joint assemblies 52 is fixedly installed on the adjacent first mounting block 23;

[0051] The support assembly 6 includes fixed rods 61 and telescopic rods 62. Multiple fixed rods 61 are evenly and uniformly fixedly installed on the lower side of the first support member 11 and the second support member 12. Multiple fixed rods 61 are evenly and uniformly fixedly installed on the lower support rod 22 and the lower hydraulic telescopic rod 32. One end of the telescopic rod 62 is hinged to the lower support rod 22, and the other end of the telescopic rod 62 is hinged to the output end of the lower hydraulic telescopic rod 32.

[0052] In this embodiment, when the fixed triangular member 2, the deformable triangular member 3, the first universal joint component 51, the second universal joint component 52, and the support component 6 are working normally, the first universal joint component 51 and the second universal joint component 52 enable the connecting components at both ends to rotate relative to each other in multiple dimensions (up, down, left, and right). The first support component 11, the second support component 12, and the fixing rod 61 between them form a single module, as do the lower support rod 22, the lower hydraulic telescopic rod 32, and the fixing rod 61 between them. When the ladder cage deforms vertically, the different modules rotate vertically relative to each other. When the upper hydraulic telescopic rod 4 between the side hydraulic telescopic rod 31, the lower hydraulic telescopic rod 32, and the second mounting block 33 extends or retracts, the ladder cage deforms horizontally. At this time, the different modules rotate horizontally relative to each other. The output ends of the lower support rod 22 and the lower hydraulic telescopic rod 32, as well as the telescopic rod 62 between them, act as a follow-up deformation module, deforming accordingly to ensure support in the rotation area.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
