Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a temporary support walking mechanism. Background Technology

[0002] With the rapid development of the national economy and the acceleration of urbanization, mobile temporary supports are widely used in construction, bridge, and tunnel projects. Traditional fixed supports suffer from problems such as long installation cycles, poor adaptability, and low reusability. For example, coal mine roadway construction has long relied on lifting ring-type forward-reaching beams or emulsion-filled single-column supports, but the former requires frequent manual adjustments, and the latter is difficult to deploy quickly due to its reliance on hydraulic pump stations, resulting in low construction efficiency and high labor intensity for workers. Furthermore, as modern engineering projects become more complex and large-scale, such as bridge spanning construction and open-cut subway structures, higher demands are placed on the mobility, stability, and rapid assembly / disassembly capabilities of supports.

[0003] Currently, mobile temporary support technology is mainly divided into three categories: mechanically adjustable, hydraulically driven, and intelligently controlled.

[0004] Mechanically adjustable type: Represented by modular scaffolding systems, these systems achieve flexible adjustment of height and span through the rapid assembly of steel pipes or aluminum alloy components. For example, mobile adjustable scaffolding systems use standardized components and snap-fit ​​connections, suitable for scenarios such as building decoration and equipment installation, with a load-bearing capacity of up to 1.5 kN / m. 2 However, its adjustment precision is limited and it relies on manual operation.

[0005] Hydraulically driven type: such as hydraulic lifting and moving supports, which achieve smooth lifting and lowering through hydraulic cylinders, suitable for scenarios requiring frequent height adjustments, such as automotive repair and industrial production lines. Improved telescopic supports in coal mine roadways, combined with a universal ball joint structure, can adapt to the direction of roof pressure, improving support stability. This type of support is only suitable for vertical movement and cannot be used for lateral movement.

[0006] Intelligent control type: Integrating sensors and automation technologies, such as intelligent mobile supports, these systems use laser ranging modules to monitor the distance to the target in real time and automatically adjust their position to maintain the optimal working range. These supports show potential in scenarios such as medical rescue and smart exhibition halls, but they are costly and rely on stable power supply. Additionally, stepping self-moving tail sections achieve autonomous movement through the linkage of hydraulic cylinders and guide rails, solving the problem of easy skewing in traditional belt conveyor tail sections, but their structural complexity limits their widespread adoption.

[0007] Based on this, the present invention designs a temporary support walking mechanism to solve the above problems. Summary of the Invention

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a temporary support walking mechanism.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A temporary support walking mechanism includes a moving system and a support system;

[0011] The mobile system includes a slide mechanism (1) and a mobile trolley mechanism (2). The slide mechanism (1) is installed on the ground foundation. Every two slide mechanisms (1) are set as a group, and multiple groups are installed end to end along the construction direction.

[0012] Each slide mechanism (1) is equipped with multiple mobile trolley mechanisms (2) that can move along the length of the slide mechanism (1). The leftmost and rightmost columns (6) of the temporary support are fixedly connected to the mobile trolley mechanisms (2).

[0013] The support system includes a lifting device (3), a lifting support device (4), and a lateral support frame (5). The lower ends of the columns (6) on the inner side of the temporary support are all equipped with lifting support devices (4). The lifting device (3) is installed on the ground foundation and located at the lower end of the lifting support device (4). The lifting device (3) is used to control the lifting of the temporary support by lifting the lifting support device (4). The pad (7) is installed between the lower end of the column (6) and the ground foundation. The lateral support frame (5) is fixedly installed on the outer wall of the column (6) on the outer side of the temporary support.

[0014] Furthermore, the slide mechanism (1) includes an embedded part (11), a channel steel (12) and a track (13). The embedded part (11) is fixedly installed on the ground foundation, the channel steel (12) is fixedly installed on the upper end of the embedded part (11), and the track (13) is fixedly installed on the upper end of the channel steel (12).

[0015] Furthermore, the mobile trolley mechanism (2) includes a frame (21), wheels (22) and a rail clamp (23). The lower end of the frame (21) is fixedly equipped with a plurality of wheels (22) that are tumblingly connected to the track (13), and the end of the frame (21) is equipped with a rail clamp (23) for use with the track (13).

[0016] Furthermore, at least one mobile trolley mechanism (2) is equipped with a power unit for driving the mobile trolley mechanism (2) to move along the track (13).

[0017] Furthermore, the lifting support device (4) includes a transverse channel steel (41) and an oblique channel steel (42).

[0018] Furthermore, the lower ends of the columns (6) on the inner side of the temporary support and the lateral support frame (5) are suspended in the air.

[0019] Furthermore, the angle between the lateral support frame (5) and the ground foundation is forty-five degrees.

[0020] Furthermore, there are two lifting devices (3) that are symmetrically distributed on both sides of the track (13).

[0021] Compared with the prior art, the present invention has the following advantages: The present invention achieves horizontal movement and fixed-point support of temporary supports through the cooperation of the moving system and the support system, effectively avoiding the cumbersome steps of repeated disassembly and installation when moving temporary supports. The sliding mechanism and the moving trolley mechanism can ensure the reliability and anti-overturning ability of the temporary supports when moving. When the temporary supports are stationary, the overall cavity is increased by the lateral support frame. The entire mechanism has a simple structure, low cost, low dependence on manual labor, wide applicability, and high degree of promotion. While ensuring construction safety, it effectively shortens the construction period and saves construction costs. Attached Figure Description

[0036] 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.

[0037] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-11 A temporary support walking mechanism includes a moving system and a support system;

[0038] The mobile system includes a slide mechanism (1) and a mobile trolley mechanism (2). The slide mechanism (1) is installed on the ground foundation. Every two slide mechanisms (1) are set as a group, and multiple groups are installed end to end along the construction direction.

[0039] Each slide mechanism (1) is equipped with multiple moving trolley mechanisms (2) that can move along the length of the slide mechanism (1). The leftmost and rightmost columns (6) of the temporary support are fixedly connected to the moving trolley mechanisms (2) by high-strength bolts. The columns (6) inside the temporary support are suspended to avoid interference between the columns (6) and the ground when the temporary support is moved. The lowest point of the columns (6) inside the temporary support is about 100 mm above the ground.

[0040] The support system includes a lifting and lowering device (3), a lifting and lowering support device (4), and a lateral support frame (5). The lower ends of the columns (6) on the inner side of the temporary support are all equipped with lifting and lowering support devices (4). Two lifting and lowering devices (3) are installed on the ground foundation and symmetrically distributed on the left and right sides of the lower end of the lifting and lowering support devices (4). The lifting and lowering devices (3) are used to control the lifting of the temporary support by lifting the lifting and lowering support devices (4). The lifting and lowering devices (3) are hydraulic jacks. The pads (7) are installed between the lower end of the columns (6) and the ground. The outer side wall of the columns (6) on the outer side of the temporary support is fixedly installed with a lateral support frame (5). The lower end of the lateral support frame (5) is suspended in the air. The angle between the lateral support frame (5) and the ground foundation is 45 degrees.

[0041] In this invention, by controlling the movement of the trolley mechanism (2) along the direction of the slide mechanism (1), the trolley mechanism (2) can be moved horizontally. When the trolley mechanism (2) moves to the set position, the trolley mechanism (2) automatically stops. The lifting device (3) lifts the lifting support device (4) upward, and then moves the pad (7) between the lower end of the column (6) and the ground and between the lower end of the side support frame (5) and the ground. Then the lifting device (3) drives the lifting support device (4) to reset, so that the column (6) and the side support frame (5) fall on the pad (7), achieving a stable support and leveling effect for the temporary support. The side support frame (5) can make the temporary support more stable. After the construction is completed, the lifting device (3) lifts the lifting support device (4) upward to move the pad (7) out, so that the trolley mechanism (2) drives the temporary support to move to the next working area.

[0042] Please see Figure 6 , Figure 10 and Figure 11The slide mechanism (1) includes an embedded part (11), a channel steel (12), and a track (13). The embedded part (11) consists of a top support plate and a plug welded to the lower end of the support plate for insertion into the foundation. The channel steel (12) is fixedly installed on the upper end of the support plate of the embedded part (11). The channel steel (12) can be fixed to the support of the embedded part (11) by welding with a plate. The track (13) is fixedly installed on the upper end of the channel steel (12). Adjacent tracks (13) are fixedly connected by bolts. The length of each track (13) is 900 mm.

[0043] Please see Figure 4 , Figure 5 and Figure 6 The mobile trolley mechanism (2) includes a frame (21), wheels (22) and a rail clamp (23). Multiple wheels (22) that are rolled and connected to the track (13) are fixedly installed at the lower end of the frame (21). A rail clamp (23) that is used in conjunction with the track (13) is also installed at the end of the frame (21).

[0044] At least one mobile trolley mechanism (2) is equipped with a power unit, which includes a motor (24), a reducer (25) and a transmission assembly (26). The motor (24) and the reducer (25) are fixedly connected to the frame (21). The input end of the reducer (25) is fixedly connected to the output end of the motor (24). The output end of the reducer (25) is connected to the traveling wheel (22) through the transmission assembly (26). The transmission assembly (26) adopts a sprocket and chain transmission structure.

[0045] In this invention, the traveling wheel (22) is driven to rotate by a power device to control the frame (21) to move along the track (13). The rail clamp (23) is used to limit the lateral movement of the traveling wheel (22) during travel to prevent the traveling wheel (22) from derailing during construction. When the moving trolley mechanism (2) is stopped, wedge blocks are placed on both sides of the traveling wheel (22) along the track (13) so that when construction is carried out after the temporary support is fixed, the movement of the traveling wheel (22) along the track (13) can be limited by the wedge blocks.

[0046] Please see Figure 7 , Figure 8 and Figure 9 The lifting support device (4) includes a transverse channel steel (41) and an inclined channel steel (42). The middle part of the transverse channel steel (41) is fixedly connected to the lower end of the column (6). Two inclined channel steels (42) are symmetrically distributed on the left and right sides of the transverse channel steel (41), and the ends of the inclined channel steels (42) are fixedly connected to the transverse channel steel (41) and the column (6) respectively. The output end of the lifting device (3) can lift the temporary support by lifting the transverse channel steel (41).

[0047] 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.
