Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a shaft operation platform. Background Technology

[0002] A shaft is a closed or semi-closed space within a building or engineering facility, enclosed by walls, floors, or steel structures, primarily used for specific functions such as vertical transportation, equipment installation, and pipeline laying. The limited movement of workers within a shaft and the risk of falls from height significantly increase the operational difficulty of shaft construction.

[0003] In existing technologies, temporary work platforms are often installed within the shaft to provide operating space for construction workers. These platforms employ a modular design, are easy to install and disassemble, and can be raised synchronously with the floor level, providing a certain level of safety for workers and significantly improving construction efficiency. However, when adapting to shafts of different sizes, existing technologies generally rely on replacing crossbeams, longitudinal beams, and other components of corresponding dimensions. This not only makes adjusting the size of the work platform inconvenient but also increases usage costs and limits its applicability. Furthermore, the height of the work platform's uprights is generally fixed, and cannot be adjusted adaptively for floors with different heights, further restricting the platform's applicability.

[0004] Therefore, there is an urgent need for a wellbore operation platform to solve the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0048] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] like Figures 1 to 11 As shown, this embodiment provides a hoistway operation platform that is applicable to hoistway operations with different dimensions in the first direction, second direction, and vertical direction, thereby reducing usage costs and expanding versatility.

[0051] See Figure 1 and Figure 2 The hoistway working platform includes a support base 1, a vertical support unit 2, and a horizontal support unit 3. The support base 1 can be installed on the side wall of the hoistway; the vertical support unit 2 is positioned along the vertical direction ( Figure 1 The horizontal support unit 3 is movably mounted on the support base 1 in the Z direction; the horizontal support unit 3 includes a first horizontal support component 31 and a second horizontal support component 32, the first horizontal support component 31 being detachably mounted on the vertical support unit 2 and along the first direction (Z direction); Figure 2 The first horizontal support component 31 extends along the X direction, and its extension length is adjustable. The second horizontal support component 32 extends along the first direction and the second direction. Figure 2 The first horizontal support component 31 can be movably set in the Y direction, and the second horizontal support component 32 extends along the second direction, and the extension length of the second horizontal support component 32 is adjustable; the first direction, the second direction and the vertical direction are perpendicular to each other.

[0052] The hoistway work platform provided in this embodiment can change the height of the vertical support unit 2 within the hoistway by moving its position on the support base 1, making the hoistway work platform suitable for construction of buildings with multiple floors. The lengths of both the first horizontal support component 31 and the second horizontal support component 32 are adjustable, allowing the hoistway work platform to be used in hoists of different lengths and widths. Compared with existing technologies, this hoistway work platform can adjust its dimensions along the first, second, and vertical directions without replacing components, adapting to hoists and buildings of different specifications, significantly reducing its operating costs and expanding its versatility. Furthermore, when the length of the first horizontal support component 31 changes, the position of the second horizontal support component 32 on the first horizontal support component 31 can be changed to ensure the uniformity and stability of the force on both components, improving the safety of workers operating on the hoistway work platform.

[0053] Optionally, see Figure 2 , Figure 3 and Figure 4 The vertical support unit 2 includes a vertical support member 211 and a vertical connector. The vertical support member 211 is slidably connected to the support base 1 in the vertical direction. One of the vertical support member 211 and the support base 1 is provided with a plurality of first vertical adjustment holes 11 arranged at intervals in the vertical direction. The other of the vertical support member 211 and the support base 1 is provided with a plurality of second vertical adjustment holes 2111. The second vertical adjustment holes 2111 can be aligned with any one of the first vertical adjustment holes 11. The vertical connector can be inserted into or detached from the second vertical adjustment holes 2111 and the first vertical adjustment holes 11 aligned with the second vertical adjustment holes 2111. When the vertical connector is inserted into the second vertical adjustment hole 2111 and the first vertical adjustment hole 11, it can restrict the relative sliding between the vertical support 211 and the support base 1, thereby fixing the vertical position of the vertical support 211. When the vertical connector is disengaged from the second vertical adjustment hole 2111 and the first vertical adjustment hole 11, the vertical support 211 can move relative to the support base 1, and the first vertical adjustment hole 11 aligned with the second vertical adjustment hole 2111 changes, thereby adjusting the vertical position of the vertical support 211 in the shaft. The operation is convenient and quick.

[0054] In this embodiment, see Figure 4 The first vertical adjustment hole 11 is provided on the support base 1, and the second vertical adjustment hole 2111 is provided on the vertical support member 211. In other embodiments, the first vertical adjustment hole 11 is provided on the support base 1, and the second vertical adjustment hole 2111 is provided on the vertical support member 211.

[0055] In this embodiment, see Figure 4Multiple second vertical adjustment holes 2111 are provided, and at least a portion of the multiple first vertical adjustment holes 11 can be aligned one-to-one with at least a portion of the multiple second vertical adjustment holes 2111 to form several pairs of mutually aligned through holes. The number of pairs of through holes varies depending on the position of the vertical support member 211 on the support base 1. Multiple vertical connectors are provided, the number of which is determined by the number of pairs of through holes; as long as one vertical connector is inserted into each pair of through holes. When there are multiple through holes, and each is equipped with a vertical connector, the connection strength between the vertical connector and the support base 1 can be significantly improved.

[0056] Optionally, see Figure 2 and Figure 3 The vertical support unit 2 includes a connecting component 22 and multiple vertical support components 21. The multiple vertical support components 21 are arranged at intervals along a first direction or a second direction. A first horizontal support component 31 is detachably connected to the multiple vertical support components 21. Adjacent vertical support components 21 are connected by the connecting component 22, and the spacing between adjacent vertical support components 21 is adjustable. When the length of the first horizontal support component 31 and / or the second horizontal support component 32 changes, the support position of the vertical support component 21 on the horizontal support unit 3 can be changed by adjusting the spacing between the two vertical support components 21, thereby ensuring the stability of the wellhead work platform. The connecting component 22 can connect adjacent vertical support components 21 into a whole, improving the overall integrity of the vertical support unit 2 and ensuring the stability of the vertical support unit 2.

[0057] In this embodiment, see Figure 3 Multiple vertical support components 21 are arranged at intervals along the second direction. Each vertical support component 21 includes a vertical support member 211 and an inclined support member 212. The upper end of the inclined support member 212 is connected to the first horizontal support component 31, and the lower end of the inclined support member 212 is connected to the vertical support member 211. The inclined support member 212 is vertically inclined, and the vertical support member 211 extends in the vertical direction. Thus, the inclined support member 212, the vertical support member 211, and the first horizontal support component 31 form a triangle, which improves the strength of the vertical support component 21.

[0058] Specifically, see Figure 2 and Figure 4The vertical support assembly 21 also includes a connecting plate 213, and the inclined support member 212 is connected to the connecting plate 213. The connecting plate 213 is provided with a third vertical adjustment hole 2131 and a fourth vertical adjustment hole 2132. The fourth vertical adjustment hole 2132 is located on the side of the third vertical adjustment hole 2131 away from the support base 1. The third vertical adjustment hole 2131 can be aligned with a first vertical adjustment hole 11, and the fourth vertical adjustment hole 2132 can be aligned with a second vertical adjustment hole 2111. The vertical connector includes a first pin and a second pin. The first pin can be inserted into the aligned third vertical adjustment hole 2131 and first vertical adjustment hole 11 to connect the support base 1 to the connecting plate 213. The second pin can be inserted into the aligned fourth vertical adjustment hole 2132 and second vertical adjustment hole 2111 to connect the vertical support member 211 to the connecting plate 213. The connection plate 213 can also increase the connection strength between the vertical support 211 and the support base 1, further improving the stability and safety of the well platform operation.

[0059] For example, both the first and second pins are pivot pins. The connecting plate 231 is a corbel plate, which effectively resists bending moments and shear forces, enhancing the structural stability of the connection between the vertical support assembly 21 and the support base 1. See also... Figure 3 The vertical support component 21 is provided with connecting plates 213 on both sides along the horizontal direction, which helps to further increase the connection strength between the vertical support component 211 and the support base 1.

[0060] Specifically, see Figure 3 The vertical support assembly 21 also includes a reinforcing rod 214 that extends horizontally or is inclined vertically. One end of the reinforcing rod 214 is connected to the vertical support member 211, and the other end is connected to the inclined support member 212, so that multiple triangular structures can be formed between the vertical support assembly 21 and the first horizontal support assembly 31. This helps to further improve the structural integrity and structural stability of each vertical support assembly 21 and ensure the safety of the wellhead operation platform.

[0061] For example, both the vertical support 211 and the inclined support 212 are made of steel pipes, and the cross-sectional shape of both the vertical support 211 and the inclined support 212 includes, but is not limited to, rectangles, squares and circles.

[0062] In this embodiment, see Figure 3 and Figure 5The vertical support unit 2 also includes a connecting plug. The vertical support component 21 has a first position adjustment hole 215, and the connecting component 22 has multiple second position connecting holes 221 spaced apart along its extension direction. The first position adjustment hole 215 can be aligned with any one of the second position connecting holes 221 of the connecting component 22. The connecting plug can be inserted into or detached from the first position adjustment hole 215 and the second position connecting hole 221 aligned with it. When the connecting plug is inserted into the aligned first position adjustment hole 215 and second position connecting hole 221, it restricts the relative position between the connecting component 22 and the vertical support component 21, ensuring the structural stability of the vertical support unit 2 during operation. When the connecting plug detaches from the aligned first position adjustment hole 215 and second position connecting hole 221, the connecting component 22 can move relative to the vertical support component 21, allowing adjustment of the spacing between adjacent vertical support components 21. When the first position adjustment hole 215 is aligned with different second position connection holes 221, the connection position of the connecting component 22 and the vertical support component 21 is different, so as to adapt to the adjustment of the distance between two adjacent vertical support components 21.

[0063] Specifically, see Figure 3 The vertical support assembly 21 includes a vertical support member 211 and an inclined support member 212. The connecting assembly 22 includes a plurality of first connecting rods 222 and a plurality of second connecting rods 223. The plurality of first connecting rods 222 are arranged at intervals along the vertical direction, and adjacent two vertical support members 211 are connected by the first connecting rods 222. The plurality of second connecting rods 223 are arranged at intervals along the extension direction of the inclined support members 212, and adjacent two inclined support members 212 are connected by the second connecting rods 223. Both the first connecting rods 222 and the second connecting rods 223 are provided with a plurality of second position connecting holes 221, so that the first connecting rods 222 can connect to adjacent two vertical support members 211 and adapt to the adjustment of the distance between the two vertical support members 211, and the second connecting rods 223 can connect to adjacent two inclined support members 212 and adapt to the adjustment of the distance between the two inclined support members 212.

[0064] For example, see Figure 3 The first connecting rod 222 extends horizontally, or the first connecting rod 222 is set vertically at an angle; the second connecting rod 223 extends horizontally, or the second connecting rod 223 is set vertically at an angle.

[0065] Preferably, during the production process, the lengths of the first connecting rod 222 and the second connecting rod 223 are set to be larger, so that when the distance between two adjacent vertical support components 21 increases, the longer first connecting rod 222 and the second connecting rod 223 can still connect the two vertical support components 21.

[0066] For example, both the first connecting rod 222 and the second connecting rod 223 are made of steel pipe, and the cross-sectional shape of the first connecting rod 222 and the second connecting rod 223 includes, but is not limited to, rectangle, square and circle.

[0067] Optionally, see Figure 2 , Figure 3 and Figure 6 The horizontal support unit 3 further includes a plurality of connectors 33 movably disposed on the first horizontal support assembly 31 along a first direction. The second horizontal support assembly 32 is provided with a plurality of connection hole groups arranged at intervals along the first direction, each connection hole group corresponding to a plurality of connectors 33. The connection hole groups include a plurality of limiting holes 321 arranged at intervals along a second direction. The connectors 33 can be inserted into any number of limiting holes 321 of the corresponding connection hole group to connect the first horizontal support assembly 31 and the second horizontal support assembly 32. When the second horizontal support assembly 32 moves relative to the first horizontal support assembly 31 along the first direction, it drives the connectors 33 to move, so that the connectors 33 can always be inserted into the corresponding connection hole groups to restrict the position of the second horizontal support assembly 32 on the first horizontal support assembly 31. When the second horizontal support assembly 32 moves relative to the first horizontal support assembly 31 along the second direction, the connectors 33 can restrict the position of the second horizontal support assembly 32 in the second direction by inserting into different limiting holes 321.

[0068] In this embodiment, see Figure 6 and Figure 7 The first horizontal support assembly 31 includes a plurality of first horizontal support members 311 arranged at intervals along a second direction. Each first horizontal support member 311 is provided with a plurality of connectors 33 arranged at intervals along the first direction. The second horizontal support assembly 32 includes a plurality of second horizontal support members 322 and a plurality of third horizontal support members 323 arranged at intervals along the first direction. The arrangement of the plurality of first horizontal support members 311, the plurality of second horizontal support members 322 and the plurality of third horizontal support members 323 makes the horizontal support unit 3 as a whole a planar frame structure, thereby improving the structural stability of the horizontal support unit 3.

[0069] Both the second horizontal support 322 and the third horizontal support 323 are provided with multiple limiting holes 321, so that each second horizontal support 322 and each third horizontal support 323 has a group of connecting holes. When the connector 33 is inserted into the limiting hole 321 on the second horizontal support 322, the connector 33 can connect one first horizontal support 311 to one second horizontal support 322; when the connector 33 is inserted into the limiting hole 321 on the third horizontal support 323, the connector 33 can connect one first horizontal support 311 to one third horizontal support 323.

[0070] For example, see Figure 6 and Figure 7 Both the first horizontal support member 311 and the second horizontal support assembly 32 are made of steel pipe. The connector 33 includes several U-shaped clamps 331. The first horizontal support member 311 is embedded in the U-shaped groove of the U-shaped clamp 331 and slides in cooperation with the groove wall. The two ends of the U-shaped clamp 331 can be inserted into the two limiting holes 321 one by one.

[0071] In other embodiments, the connector 33 includes a plurality of pins, each of which can be inserted into a limiting hole 321.

[0072] Specifically, see Figure 3 and Figure 8 The vertical support unit 2 includes multiple vertical support components 21, each corresponding to a multiple first horizontal support member 311. Each vertical support component 21 includes a vertical support member 211 and an inclined support member 212. The first horizontal support member 311 is provided with a first connecting seat 3115 and a second connecting seat 3116. The first horizontal support member 311 is connected to the upper end of the corresponding vertical support member 211 via the first connecting seat 3115, and the first horizontal support member 311 is connected to the upper end of the corresponding inclined support member 212 via the second connecting seat 3116.

[0073] Optionally, see Figure 2 and Figure 8 The first horizontal support assembly 31 includes a first support portion 3111 and a second support portion 3112 slidably connected along a first direction. Both the first support portion 3111 and / or the second support portion 3112 are detachably connected to the vertical support unit 2, and the overlap length of the first support portion 3111 and the second support portion 3112 is adjustable. The relative sliding of the first support portion 3111 and the second support portion 3112 changes the overlap length, thus adjusting the length of the first horizontal support assembly 31 to suit shafts of different sizes.

[0074] Specifically, see Figure 7 and Figure 8 The first horizontal support assembly 31 includes a plurality of first horizontal support members 311 arranged at intervals along a second direction. Each first horizontal support member 311 includes a first support portion 3111 and a second support portion 3112. When the overlap length of the first support portion 3111 and the second support portion 3112 increases, the length of the first horizontal support member 311 decreases, and the length of the first horizontal support assembly 31 decreases; when the overlap length of the first support portion 3111 and the second support portion 3112 decreases, the length of the first horizontal support member 311 increases, and the length of the first horizontal support assembly 31 increases.

[0075] In this embodiment, see Figure 8 The first support portion 3111 and the second support portion 3112 are coaxially arranged. For example, the first support portion 3111 is a rod and the second support portion 3112 is a tube. The first support portion 3111 is slidably inserted into the second support portion 3112, and the length of overlap between the first support portion 3111 and the second support portion 3112 is the length of the first support portion 3111 inserted into the second support portion 3112.

[0076] In other embodiments, the first support portion 3111 and the second support portion 3112 are arranged at opposite axes. Exemplarily, both the first support portion 3111 and the second support portion 3112 are channel steels, the first support portion 3111 and the second support portion 3112 are arranged side by side, the first support portion 3111 and the second support portion 3112 are in contact, and the length of overlap between the first support portion 3111 and the second support portion 3112 is the length of contact.

[0077] In this embodiment, see Figure 7 and Figure 8 The first horizontal support assembly 31 further includes a first horizontal connector 312. One of the first support portion 3111 and the second support portion 3112 is provided with a plurality of first horizontal adjustment holes 3113 arranged at intervals along a first direction. The other of the first support portion 3111 and the second support portion 3112 is provided with a plurality of second horizontal adjustment holes 3114. The second horizontal adjustment holes 3114 can be aligned with any one of the first horizontal adjustment holes 3113. The first horizontal connector 312 can be inserted into or detached from the second horizontal adjustment holes 3114 and the first horizontal adjustment holes 3113 aligned with the second horizontal adjustment holes 3114. When the first horizontal connector 312 is inserted into the aligned second horizontal adjustment hole 3114 and first horizontal adjustment hole 3113, it can limit the relative sliding between the first support part 3111 and the second support part 3112 to ensure the stability of the structure during construction; when the first horizontal connector 312 is disengaged from the aligned second horizontal adjustment hole 3114 and first horizontal adjustment hole 3113, the first support part 3111 and the second support part 3112 can slide relative to each other to adjust the length of the first horizontal support assembly 31.

[0078] Specifically, see Figure 7 and Figure 8 The first horizontal support assembly 31 includes a plurality of first horizontal support members 311 arranged at intervals along the second direction. The first horizontal support members 311 are provided with a plurality of second horizontal adjustment holes 3114.

Both the third support portion 3221 and the fourth support portion 3222 are movably disposed on the first horizontal support assembly 31, and the overlap length of the third support portion 3221 and the fourth support portion 3222 is adjustable. The relative sliding of the third support portion 3221 and the fourth support portion 3222 changes the overlap length of the third support portion 3221 and the fourth support portion 3222, thus adjusting the length of the second horizontal support member 322 to suit different sizes of shafts.

[0081] The second horizontal support assembly 32 includes a plurality of third horizontal support members 323 spaced apart along a first direction. Each third horizontal support member 323 includes a fifth support portion 3231 and two sixth support portions 3232.

The relative sliding of the fifth support portion 3231 and the sixth support portion 3232 changes the overlap length, thus adjusting the length of the third horizontal support member 323 to suit different sizes of shafts. Compared to the second horizontal support member 322, the adjustable range of the length of the third horizontal support member 323 is significantly increased, and the adjustment of the third horizontal support member 323 is more flexible, expanding the adjustable range of the length of the second horizontal support assembly 32.

[0082] Specifically, see Figure 7 , Figure 9 and Figure 10When the overlap length between the third support portion 3221 and the fourth support portion 3222 increases, the length of the second horizontal support member 322 decreases, and the length of the second horizontal support assembly 32 decreases; when the overlap length between the third support portion 3221 and the fourth support portion 3222 decreases, the length of the second horizontal support member 322 increases, and the length of the second horizontal support assembly 32 increases. When the overlap length between the fifth support portion 3231 and the sixth support portion 3232 increases, the length of the third horizontal support member 323 decreases, and the length of the second horizontal support assembly 32 decreases; when the overlap length between the fifth support portion 3231 and the sixth support portion 3232 decreases, the length of the third horizontal support member 323 increases, and the length of the second horizontal support assembly 32 increases.

[0083] In this embodiment, see Figure 9 The third support portion 3221 and the fourth support portion 3222 are arranged at opposite axes. For example, both the third support portion 3221 and the fourth support portion 3222 are channel steels, and the third support portion 3221 and the fourth support portion 3222 are arranged side by side, with the third support portion 3221 and the fourth support portion 3222 fitting together, and the length of overlap between the third support portion 3221 and the fourth support portion 3222 being the length of their fitting together.
