Description

Technical Field

[0001] This utility model relates to the field of derrick technology, and more specifically, to a derrick for vertical shaft construction. Background Technology

[0002] A vertical shaft is a well-shaped pipe with upright walls, essentially a type of sinkhole. In plan view, it is square, rectangular, or irregularly circular. The shaft walls are steep, almost vertical. Vertical shafts are widely used in water conservancy and hydropower projects for water intake, water diversion, ventilation, slag removal, gas supply, and the construction of underground refuges or living quarters. Vertical shaft construction is characterized by its small footprint and minimal disruption to surrounding construction.

[0003] During shaft construction, a derrick is typically installed above the shaft. This derrick spans the shaft and is used to suspend traveling trolleys, hooks, and other equipment during construction. It is also commonly used for vertically transporting building materials or heavy equipment. However, most existing derricks have fixed dimensions, one derrick per shaft, making it impossible to adjust them according to the shaft size and actual usage. Furthermore, existing derricks cannot be easily folded, making transportation and assembly inconvenient. Utility Model Content

The screw passes through the internal thread cavity and is threaded into the internal thread cavity.

[0014] The second reducer of the second telescopic assembly is mounted on the third sleeve, and the screw of the second telescopic assembly is mounted inside the second sleeve and the third sleeve. One end of the screw of the second telescopic assembly is fixedly connected to the second sleeve.

[0015] Furthermore, the main truss and the secondary truss have the same structure, and the main truss is composed of several side plate frames connected one end to the other in sequence to form a regular polygon;

[0016] One end of the side panel frame is provided with a T-shaped groove, and the other end of the side panel frame is provided with a T-shaped head. The T-shaped head of the side panel frame is engaged with the T-shaped groove of the next side panel frame, and the T-shaped groove of the side panel frame is engaged with the T-shaped head of the previous side panel frame.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Reference Figures 1-7 as well as Figure 9 As shown, this embodiment provides a shaft scaffold for vertical shaft construction, comprising only a first support 1. The first support 1 includes a main truss 11, a secondary truss 12, support legs 13, and a drive component 14. The main truss 11 and the secondary truss 12 are arranged in parallel, and the secondary truss 12 is slidably connected to the main truss 11. In specific implementation, the secondary truss 12 serves as an extension of the main truss 11 to compensate for the insufficient length of the main truss 11. By extending the secondary truss 12, the span of the entire first support 1 is extended, thereby allowing it to be erected on vertical shafts of different diameters. Meanwhile, a suspended traveling trolley 15 is provided on the main truss 11 for installing lifting hooks and other machinery and equipment.

[0043] More specifically, such as Figure 1 and Figure 8As shown, both the main truss 11 and the secondary truss 12 are provided with a support leg 13 at their bottom. The lower end of the support leg 13 is provided with a walking wheel set 16. The walking wheel set 16 has a drive source to drive the entire first support 1 to walk or rotate around the well opening of the shaft, so that the main truss 11 can cover the entire upper part of the shaft, which facilitates the construction work on the shaft. It should be noted that the length of the main truss 11 needs to be greater than the radius of the shaft, that is, the travel of the traveling carriage 15 suspended on the main truss 11 must be at least greater than the radius of the shaft, so as to cooperate with the first support 1 to rotate around the well opening of the shaft and realize the construction covering the entire shaft surface.

[0044] like Figure 1 and Figure 10 As shown, it should be noted that this embodiment is a single frame with two supporting legs 13 and two sets of walking wheels 16. The two sets of walking wheels 16 here are responsible for the anti-tipping function of the entire support. They are usually set with a large span and multiple sets of wheels, which is easy for those skilled in the art to imagine, and will not be described in detail here.

[0045] As another embodiment, if necessary, a suspended trolley 15 can also be installed on the sub-truss 12 to increase the number of hoisting positions, but this implementation is rarely used.

[0046] More specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, the driving component 14 is mounted on the main truss 11, and is used to drive the secondary truss 12 to slide on the main truss 11. In a specific implementation, the main truss 11 and the secondary truss 12 are coaxially arranged. A sliding cavity 111 is provided on the main truss 11 along the axial direction. One end of the secondary truss 12 extends into the sliding cavity 111 and is slidably connected to the sliding cavity 111. Thus, the secondary truss 12 is coaxially extended and retracted along the main truss 11.

[0047] like Figure 6 As shown, there are several sets of drive components 14, arranged in a circular array on the main truss 11. In specific implementation, each drive component 14 includes a base 141, a first reducer 142, and a drive gear 143. The base 141 is mounted on the main truss 11, the first reducer 142 is mounted on the base 141, and the drive gear 143 is located at the output end of the first reducer 142. Several toothed rails 144 are arranged in a circular array on the sub-truss 12, with one drive gear 143 meshing with one toothed rail 144. Furthermore, through the synchronous cooperation of the several first reducers 142, and with the cooperation of the drive gear 143 and the toothed rail 144, the sub-truss 12 is driven to move coaxially within the main truss 11, achieving the extension or retraction of the sub-truss 12.

[0048] More specifically, such as Figure 7As shown, the support leg 13 is a multi-stage telescopic component, which can adjust the height of the first bracket 1. This facilitates assembly at a low position and then raising the first bracket 1 to facilitate the passage of vehicles or people, or assists in hoisting or installation work on the suspended trolley 15, etc. Lowering the height of the first bracket 1 makes it easier to operate.

[0049] In specific implementation, such as Figure 7 As shown, the support leg 13 includes a first sleeve 131, a second sleeve 132, a third sleeve 133, a first telescopic component 134, and a second telescopic component 135. One end of the second sleeve 132 is slidably placed inside the first sleeve 131, and one end of the third sleeve 133 is slidably placed inside the second sleeve 132. The first telescopic component 134 is disposed between the first sleeve 131 and the second sleeve 132, and the second telescopic component 135 is disposed between the second sleeve 132 and the third sleeve 133.

[0050] The second telescopic component 135 has the same structure as the first telescopic component 134. The first telescopic component 134 includes a screw 1341 and a second reducer 1342. The second reducer 1342 is mounted on the second sleeve 132, and the screw 1341 is mounted inside the first sleeve 131 and the second sleeve 132. One end of the screw 1341 is connected to the first sleeve 131. The shaft at the output end of the second reducer 1342 is coaxially provided with an internal thread cavity 1343. The screw 1341 passes through the internal thread cavity 1343 and is threadedly engaged with the internal thread cavity 1343. The shaft at the output end of the second reducer 1342 can rotate in the forward or reverse direction, thereby driving the second sleeve 132 to move in the forward or reverse direction within the first sleeve 131, thus realizing the extension or retraction of the second sleeve 132 within the first sleeve 131.

[0051] The second reducer 1342 of the second telescopic component 135 is mounted on the third sleeve 133. The screw 1341 of the second telescopic component 135 is mounted inside the second sleeve 132 and the third sleeve 133. One end of the screw 1341 is fixedly connected to the second sleeve 132. Similarly, the second reducer 1342 of the second telescopic component 135 drives the third sleeve 133 to extend or retract inside the second sleeve 132, thereby realizing the extension or retraction of the entire support leg 13, so as to control the height and level of the first bracket 1.

[0052] The main truss 11 and the secondary truss 12 have the same structure, except that the size of the secondary truss 12 is slightly smaller than the sliding cavity 111 of the main truss 11. This is to ensure that the secondary truss 12 can slide within the sliding cavity 111 of the main truss 11, and that the two are always coaxial.

[0053] In specific implementation, such as Figures 1-5As shown, the main truss 11 is composed of several side panel frames 112 connected sequentially to form a regular polygon. One end of each side panel frame 112 has a T-slot 1121, and the other end has a T-shaped head 1122. The T-shaped head 1122 of the side panel frame 112 engages with the T-slot 1121 of the next side panel frame 112, and the T-slot 1121 of the side panel frame 112 engages with the T-shaped head 1122 of the previous side panel frame 112. Typically, there are four side panels connected sequentially to form a rectangle. The frame of the side panel is a geometric structure composed of straight bars, usually based on triangular units to form a planar or spatial structure, ensuring structural strength while maintaining a relatively light weight. Figure 9 As shown, both the main truss 11 and the secondary truss 12 can be disassembled separately, facilitating folded storage, folded transportation, quick disassembly and quick assembly. Especially when it involves long distances or extraterrestrial transportation, such as transporting from Earth to celestial bodies like the Moon, the disassembly and folding function of this solution has good application prospects.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, both ends of the main truss 11 and the secondary truss 12 are equipped with locking components 17. Each locking component 17 includes a locking ring 171 and several locking tubes 172. The locking ring 171 is a regular polygon, usually a rectangular frame. Several locking tubes 172 are arranged in a circular array on the locking ring 171. At the same time, several spring plates 173 are arranged in a circular array at one end of each locking tube 172. The ends of a set of T-shaped heads 1122 and T-shaped grooves 1121 that fit together pass through a set of several spring plates 173 and are placed inside the locking tubes 172. Clamps 174 are fitted on the spring plates 173. The clamps 174 hold the ends of the T-shaped heads 1122 and T-shaped grooves 1121 tightly, thereby limiting and fixing both ends of the main truss 11 and the secondary truss 12, ensuring that the T-shaped heads 1122 and T-shaped grooves 1121 will not separate or misalign, and further enhancing the overall structural strength.

[0055] Example 2:

[0056] Based on Embodiment 1, it also includes a second support 2, which has the same structure as the first support 1; the second support 2 intersects with the first support 1, and the main truss 11 of the second support 2 is connected to the main truss 11 of the first support 1.

[0057] In practice, the main truss 11 of the second support 2 is fixedly connected to the main truss 11 of the first support 1. Typically, the second support 2 and the first support 1 are arranged perpendicularly to each other, which can prevent the overturning of a single first support 1 and enhance the structural strength and lifting capacity of the entire derrick.

[0058] As another implementation, the second support 2 and the first support 1 can rotate in the plane while being fixed to each other, that is, they are hinged to each other, and the extension shape of the derrick can be adjusted according to the terrain to meet the actual use.

[0059] Example 3:

[0060] like Figures 1-8 As shown, the second support 2 is located above the first support 1, and the first support 1 is connected to the suspended trolley 15 on the second support 2. Thus, the first support 1 and the second support 2 can slide relative to each other, ensuring that the second support 2 is always positioned above the suspended trolley 15 on the first support 1, thereby enhancing the load-bearing capacity of the suspended trolley 15 on the first support 1. Similarly, the first support 1 can also be hinged to the suspended trolley 15 on the second support, allowing adjustment of the angle between them during sliding to adapt the support configuration to the terrain.

[0061] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
