Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a device for protecting cavities. Background Technology

[0002] like Figure 1 As shown, the protective equipment 10 typically includes a hollow support portion 101. In this way, the support portion 101 can form a cavity 102, allowing workers to enter the cavity 102 to perform operations.

[0003] In this configuration, when workers are working inside cavity 102, the top of cavity 102 is exposed to the outside, posing a safety hazard, especially since there is no protection above the cavity, which could lead to falling object accidents. To address this issue, the traditional method is to temporarily construct a protective structure using steel pipes to cover the cavity 102, thereby ensuring the safety of workers inside.

[0004] However, while this traditional protection method can achieve the desired effect, it requires workers to manually assemble the steel pipes, which is time-consuming, labor-intensive, and has low protection efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for protecting cavities. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A device for protecting a cavity includes a connecting mechanism selectively disposed within the cavity and sealed at the top, and a plurality of support mechanisms disposed circumferentially along the connecting mechanism, wherein protective mechanisms for covering the cavity are selectively disposed on the support mechanisms.

[0007] The support mechanism and the connecting mechanism are rotatably connected, so that the axis of the support mechanism can be perpendicular to the axis of the connecting mechanism in a selectable manner to cover the cavity.

[0008] Furthermore, the connecting mechanism includes a mounting base with a plurality of mounting portions arranged circumferentially on the radially outer side of the mounting base. The mounting portions are used to form a space for placing the support mechanism. A rotating mechanism is also provided in the space. The rotating mechanism is configured to allow rotational connection with the end of the support mechanism, so that the end of the support mechanism can rotate within the space.

[0009] Furthermore, the mounting portion includes a first mounting plate and a second mounting plate disposed opposite to the first mounting plate, the first mounting plate and the second mounting plate together forming a space for mounting support mechanism.

[0010] Furthermore, the rotating mechanism includes a rotating shaft disposed between the first mounting plate and the second mounting plate, and a rotating part disposed at the end of the support mechanism. The rotating part is configured to pass through the rotating shaft so that the rotating part can rotate around the rotating shaft.

[0011] Furthermore, the connecting mechanism also includes a limiting part that is fixed relative to the mounting part, and a limiting groove is formed on the limiting part along the circumferential direction. The limiting groove is configured to correspond to the space formed by the first mounting plate and the second mounting plate, so as to allow the support mechanism to pass through and enable the support mechanism to form a range of motion of "0 degrees to 90 degrees" on the mounting part.

[0012] Furthermore, the support mechanism includes a support rod connected to the rotating part, and a plurality of retaining rings are provided on the support rod, the retaining rings being configured to allow relative fixation with the protective mechanism.

[0013] Furthermore, the device for protecting the cavity also includes a retraction mechanism configured to fix the respective support mechanisms together when the axes of the support mechanisms are parallel to the axes of the connecting mechanisms.

[0014] Furthermore, the gathering mechanism includes a gathering block disposed at the free end of the support rod, a through hole provided on the gathering block, and a gathering rope selectively disposed in the through hole, the gathering rope passing through each of the through holes in sequence to connect each of the gathering blocks together.

[0015] Furthermore, the protective mechanism includes a protective net disposed between each of the support rods, and spring buckles selectively disposed on the protective net, the spring buckles being configured to allow passage through a retaining ring and being fixed relative to the retaining ring.

[0016] Furthermore, the protective mechanism also includes a protective membrane disposed on the protective net, the protective membrane being configured to allow the mesh formed by the protective net to be sealed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention includes a connecting mechanism and several supporting mechanisms arranged circumferentially along the connecting mechanism. A protective mechanism for covering the cavity is selectively provided on each of the supporting mechanisms. The supporting mechanisms and the connecting mechanism are rotatably connected, allowing the axis of the supporting mechanism to be selectively perpendicular to the axis of the connecting mechanism to cover the cavity. In this way, when cavity protection is needed, the supporting mechanism can rotate along the connecting mechanism, with its free end positioned at the top of the support. This allows the protective mechanism on the supporting mechanism to cover the cavity, achieving a protective effect and avoiding the need for temporary steel pipe installations, thus improving the efficiency of protective facility deployment.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] To better understand the purpose, structure, and function of this utility model, the following detailed description of a device for protecting cavities, in conjunction with the accompanying drawings, is provided.

[0030] For convenience, the direction extending along the support will be referred to as "axial direction", "vertical direction" or similar terms, and the direction perpendicular to the "axial direction" will be referred to as "radial direction" or "horizontal direction" or similar terms.

[0031] like Figure 1 As shown, the protective equipment 10 typically includes a support portion 101. In this embodiment, the support portion 101 is configured as a hollow cylindrical structure. In this way, the support portion 101 can form a cavity 102, allowing workers to enter the cavity 102 to perform operations.

[0032] Figure 2 The schematic diagram illustrates the overall structure of the device for protecting a cavity according to the present invention. In such a way... Figure 2 In the illustrated embodiment, the device 100 for protecting the cavity includes a connecting mechanism 1 selectively disposed within the cavity 102 and sealed at the top, and a plurality of support mechanisms 2 disposed circumferentially along the connecting mechanism 1. A protective mechanism 3 is selectively disposed on the support mechanisms 2, the protective mechanism 3 being configured to allow coverage of the cavity 102.

[0033] In one embodiment, such as Figure 2 As shown, the support mechanism 2 and the connecting mechanism 1 are rotatably connected. This allows the support mechanism 2 to rotate along the connecting mechanism 1. In this configuration, the axis of the support mechanism 2 can be selectively perpendicular to the axis of the connecting mechanism 1.

[0034] Specifically, such as Figure 2As shown, the support mechanism 2 can be in an extended state and a retracted state on the connecting mechanism 1. When the support mechanism 2 is in the extended state, its axis is perpendicular to the axis of the connecting mechanism 1. This allows it to cover the cavity 102. When the support mechanism 2 is in the retracted state, its axis is parallel to the axis of the connecting mechanism 1. This makes the device easy to store.

[0035] In this configuration, when the cavity 102 of the device 100 needs to be covered to achieve protection, firstly, a force is applied to the device 100, causing the connecting mechanism 1 to be positioned on the cavity 102. Simultaneously, a force is applied to the supporting mechanism 2, causing the supporting mechanism 2 to rotate along the connecting mechanism 1.

[0036] During this process, the free end of the support mechanism 2 is positioned at the top of the support portion 101, thereby allowing the free end of the support mechanism 2 to be supported by the support portion 101. At this time, the protective mechanism 3 located on the support mechanism 2 can cover the cavity 102. Thus, the cavity 102 can be protected.

[0037] In one embodiment, such as Figure 3 As shown, the connecting mechanism 1 includes a mounting base 11, and a plurality of mounting portions 12 are arranged circumferentially on the radially outer side of the mounting base 11. In this embodiment, the mounting portions 12 are used to form a space for placing the support mechanism 2.

[0038] In the illustrated embodiment, such as Figure 4 As shown, a rotating mechanism 4 is also provided within the space. The rotating mechanism 4 is configured to allow rotational connection to the end of the support mechanism 2, enabling the end of the support mechanism 2 to rotate within the space. In this way, the support mechanism 2 can unfold and retract as it rotates along the rotating mechanism 4. Therefore, the support mechanism 2 can selectively protect the cavity 102.

[0039] In this embodiment, as Figure 3 , 4 As shown, the mounting part 12 includes a first mounting plate 121 and a second mounting plate 122 disposed opposite to the first mounting plate 121. The first mounting plate 121 and the second mounting plate 122 are used to jointly form the space for mounting support mechanism 2.

[0040] At the same time, such as Figure 4 , 6As shown, the rotating mechanism 4 includes a rotating shaft 41 disposed between the first mounting plate 121 and the second mounting plate 122, and a rotating part 42 disposed at the end of the support mechanism 2. In this embodiment, the rotating part 42 is configured to pass through the rotating shaft 41, so that the rotating part 42 can rotate around the rotating shaft 41. In this way, the support mechanism 2 can be unfolded and retracted during the rotation of the rotating part 42 around the rotating shaft 41.

[0041] In one embodiment, such as Figure 5 As shown, the connecting mechanism 1 also includes a limiting part 13 that is fixed relative to the mounting part 12. A limiting groove 131 is formed on the limiting part 13 along the circumferential direction. The limiting groove 131 is configured to correspond to the space formed by the first mounting plate 121 and the second mounting plate 122, so that the support mechanism 2 can pass through and the support mechanism 2 can form a range of motion of "0 degrees to 90 degrees" on the mounting part 12.

[0042] Specifically, the limiting part 13 allows the included angle between the support mechanism 2 and the mounting part 12 to be in the range of "0 degrees to 90 degrees". That is, when the included angle between the support mechanism 2 and the mounting part 12 is 0 degrees, the axis of the support mechanism 2 is parallel to the axis of the mounting part 12, and the support mechanism 2 is in a retracted state; while when the included angle between the axis of the support mechanism 2 and the axis of the mounting part 12 is 90 degrees, the support mechanism 2 and the mounting part 12 are perpendicular to each other, and the support mechanism 2 is in an extended state.

[0043] In one embodiment, such as Figure 6 As shown, the support mechanism 2 includes a support rod 21 connected to the rotating part 42. Several retaining rings 22 are also provided on the support rod 21, and the retaining rings 22 are configured to allow relative fixation with the protective mechanism 3. Furthermore, the device 100 for protecting the cavity also includes a retracting mechanism 5, which is configured to fix each of the support mechanisms 2 relative to each other when the axis of the support mechanism 2 is parallel to the axis of the connecting mechanism 1.

[0044] In one embodiment, such as Figure 6 As shown, the gathering mechanism 5 includes a gathering block 51 disposed at the free end of the support rod 21, and a through hole 511 is provided on the gathering block 51. The gathering mechanism 5 also includes a gathering rope (not shown in the figure). In the illustrated embodiment, the gathering rope is configured to be selectively threaded through the through hole 511.

[0045] In this configuration, when the support mechanism 2 is in the retracted state, the retracting rope can be passed sequentially through the through holes 511 on each retracting block 51. Simultaneously, the two ends of the retracting rope are fixed together. Thus, the retracted support mechanism 2 can be relatively fixed together using the retracting rope. This makes the device 100 easy to store.

[0046] In one embodiment, such as Figure 2 , 7 As shown, the protective mechanism 3 includes a protective net 31 disposed between adjacent support rods 21, and spring buckles 32 selectively disposed on the protective net 31. The spring buckles 32 are configured to allow passage through retaining rings 22 and are fixedly attached to retaining rings 22. This allows the protective net 31 to be stably disposed between the support rods 21. In this configuration, the protective net 31 can stably protect the cavity 102. It should be noted that the structure of the spring buckles 32 and their connection with the retaining rings 22 are well known to those skilled in the art.

[0047] According to a preferred embodiment of the present invention, the protective mechanism 3 further includes a protective membrane (not shown) disposed on the protective net 31. In this embodiment, the protective membrane is configured to allow sealing of the mesh formed by the protective net 31. In this way, the protective mechanism 3 can seal the cavity 102. Thus, the cavity 102 can be fully protected.

[0048] In one embodiment, such as Figure 2 As shown, a lifting part 14 is also provided on the connecting mechanism 1. The lifting part 14 is configured to allow it to be fixed relative to a lifting device (not shown) in a selective manner. This arrangement allows the device 100 to be lifted by the lifting device. This reduces the labor intensity of installing the device 100.

[0049] According to a preferred embodiment of the present invention, such as Figure 2 The lifting section 14 shown includes a first lifting ring 141 disposed on the connecting mechanism 1, and a lifting rope 142 connected to the first lifting ring 141. The lifting section 14 also includes a second lifting ring 143 disposed at the end of the lifting rope 142, the second lifting ring 143 being configured to allow relative fixation with a lifting device (not shown in the figure).

[0050] According to a preferred embodiment of the present invention, such as Figure 5As shown, the opening of the limiting part 13 faces downward. Specifically, the opening of the limiting groove 131 is located on the opposite side of the first lifting ring 141. In this way, the support mechanism 2 located in the limiting groove 131 can be limited by the limiting groove 131 in the unfolded state, while in the storage process, the support mechanism 2 can move downward under the force of gravity, thereby achieving the effect of easy storage.

[0051] The operation of the device 100 for protecting cavities according to this utility model is as follows.

[0052] First, the second lifting ring 143 is fixed relative to the lifting equipment (not shown in the figure). Simultaneously, the lifting equipment is started. During this process, the lifting equipment will continuously apply force to the device 100 until the connecting mechanism 1 is positioned appropriately above the cavity 102.

[0053] At this time, a force is applied to the support rod 21. During this process, the support rod 21 will drive the rotating part 42 to rotate along the rotating shaft 41 until the axis of the support rod 21 is perpendicular to the axis of the connecting mechanism 1. Specifically, this causes the support mechanism 2 to be in the unfolded state.

[0054] Simultaneously, the device 100 is continuously moved downwards using hoisting equipment until the free end of the support mechanism 2 is located at the top of the support portion 101, thereby allowing the free end of the support mechanism 2 to be supported by the support portion 101. During this process, the protective mechanism 3 located on the support mechanism 2 covers the cavity 102. Then, the second hoisting ring 143 is detached from the hoisting equipment. Thus, the protection of the cavity 102 is achieved.

[0055] However, when the protective work is completed and the device 100 needs to be stored, firstly, the second lifting ring 143 is fixed relative to the lifting equipment (not shown in the figure).

[0056] Simultaneously, the hoisting equipment is activated. During this process, the hoisting equipment continuously applies force to the device 100, causing it to move upward continuously. During this process, the support mechanism 2, under the influence of gravity, drives the rotating part 42 to rotate along the rotating shaft 41 until the axis of the support rod 21 is parallel to the axis of the connecting mechanism 1. Specifically, this causes the support mechanism 2 to be in a retracted state.

[0057] At this point, the gathering ropes (not shown in the figure) are passed sequentially through the through holes 511 on each gathering block 51. Simultaneously, the two ends of the gathering ropes are fixed together. This allows the gathered support mechanisms 2 to be relatively fixed together. Finally, the device 100 is hoisted to the desired location using hoisting equipment. This completes the storage of the device 100. However, it should be noted that by using support rods 21 of different sizes, the device 100 can also protect cavities 102 with different radial widths.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
