Description

Technical Field

[0001] This utility model relates to the field of shaft construction technology, and in particular to a rotating ladder device for shaft construction. Background Technology

[0002] During the construction of vertical shaft projects such as mines, tunnels, and water conservancy projects, workers need to move vertically up and down inside the shaft frequently and perform various operations on the shaft wall, such as support, installation, or maintenance.

[0003] Currently, the most common method for vertical passage in shafts is to install fixed steel ladders in sections on the shaft wall. However, this traditional fixed ladder has obvious drawbacks: First, its installation position is fixed, and workers can only operate in a limited area directly in front of the ladder. If they want to work on other parts of the shaft wall, they need to move up and down frequently or use unsafe lateral leaning methods, which results in low work efficiency and safety hazards. Utility Model Content

[0004] To address the problem that existing vertical ladders are fixed in position, limiting workers to a limited area directly in front of the ladder and making it inconvenient to work on other parts of the shaft wall, this invention provides a rotating ladder device for vertical shaft construction.

[0009] A spiral ladder, which is fixedly installed on the inner side of the support cylinder;

[0010] A driving component, which is mounted on an annular base, is used to drive the support cylinder to rotate.

[0011] As a further description of the above technical solution:

[0012] The support cylinder includes:

[0013] The inner and outer rings are arranged concentrically, and the inner and outer rings are fixed by a frame;

[0016] The spiral staircase includes:

[0017] Support members are fixedly connected to both the inner and outer rings. Multiple support members are provided, and the multiple support members are spirally distributed along the inner side of the inner ring.

[0019] The inner side of the anti-slip steel plate is fixedly connected with a fence component.

[0020] As a further description of the above technical solution:

[0021] The support component includes: a support anchor rod and an auxiliary diagonal brace. The first end of the support anchor rod is fixedly connected to both the inner and outer rings. The second end of the support anchor rod is in a cantilever state. The auxiliary diagonal brace is fixedly connected between the bottom of the second end of the support anchor rod and the inner ring.

[0022] As a further description of the above technical solution:

[0039] Please refer to the attached document. Figures 1-6 This application illustrates a rotating ladder device for shaft construction, which provides a working platform during shaft construction operations. Specifically, it includes: an annular base 1, a support cylinder 2, a spiral ladder 4, and a driving component 5.

[0040] The support cylinder 2 is rotatably mounted on the top of the annular base 1. A window 3 is provided on the side of the support cylinder 2. A spiral ladder 4 is fixedly mounted on the inner side of the support cylinder 2. A driving component 5 is mounted on the annular base 1 to drive the support cylinder 2 to rotate.

[0041] When in use, the rotating ladder device for shaft construction is hoisted into the shaft as a whole using hoisting equipment. The ring base 1 is located at the bottom of the shaft. Users can go up and down the shaft from the spiral ladder 4. Generally, a rest platform (wider than the stair surface) is designed on the spiral ladder 4 for construction workers to rest and store tools. The support cylinder 2 directly protects the inner wall of the shaft, effectively preventing the collapse of the inner wall and ensuring the safety of construction operations. When working on the inner wall of the shaft, users can work on the window 3 area on the side of the support cylinder 2. The drive component 5 rotates the support cylinder 2 to complete the work around the inner wall of the shaft.

[0042] There can be two windows 3, that is, two construction positions distributed vertically on the inner side of the support cylinder 2.

[0043] In one embodiment, the support cylinder 2 includes: an inner ring 201 and an outer ring 202 arranged concentrically, and an annular cover 203 fixedly installed on the top of the inner ring 201 and the outer ring 202.

[0044] The inner ring 201 and the outer ring 202 are fixed together by a frame. The gap between the inner ring 201 and the outer ring 202 can be filled with expanding foam. The annular cover 203 is fixedly installed on the top of the inner ring 201 and the outer ring 202, and the annular cover 203 serves as a seal.

[0045] In one embodiment, the spiral staircase 4 includes: a support member, an anti-slip steel plate member 403, and a railing member 404.

[0046] The support member is fixedly connected to both the inner ring 201 and the outer ring 202, which not only fixes the support member itself, but also further increases the stability of the connection between the inner ring 201 and the outer ring 202. Multiple support members are provided, and the multiple support members are spirally distributed along the inner side of the inner ring 201. The anti-slip steel plate 403 is in the shape of a spiral staircase, and angle steel members are fixedly connected to both the inner and outer sides of the anti-slip steel plate 403. The angle steel members are fixedly connected to the support members. The inner side of the anti-slip steel plate 403 is fixedly connected to the guardrail 404, which plays a role in safety protection.

[0047] In one embodiment, the support includes a support anchor 401 and an auxiliary diagonal brace 402. The first end of the support anchor 401 is fixedly connected to both the inner ring 201 and the outer ring 202. The second end of the support anchor 401 is in a cantilever state. The auxiliary diagonal brace 402 is fixedly connected between the bottom of the second end of the support anchor 401 and the inner ring 201.

[0048] The supporting anchor 401, the auxiliary diagonal brace 402, and the inner part of the inner ring 201 form a stable triangular structure, ensuring that the supporting anchor 401 has sufficient structural strength, and the auxiliary diagonal brace 402 increases the stability of the cantilever position of the supporting anchor 401.

[0049] In one embodiment, the driving component 5 includes: an internal gear ring 501 fixedly connected to the inner side of the bottom of the support cylinder 2 and a driving motor 502. The driving motor 502 is fixedly installed on the annular base 1, and a gear 503 that meshes with the internal gear ring 501 is fixedly installed on the output shaft of the driving motor 502.

[0050] The drive motor 502 drives the gear 503 to rotate, which in turn drives the internal gear ring 501 to rotate, causing the support cylinder 2, which is fixed to the internal gear ring 501, to rotate.

[0051] In one embodiment, several drive motors 502 are arranged in a ring, and the several drive motors 502 drive synchronously to achieve stable rotation of the support cylinder 2.
