Description

Technical Field

[0001] The utility model relates to the technical field of Bailey truss disassembly, in particular to a slide rail device for dismantling a Bailey truss with a low clearance. Background Art

[0002] When constructing a building on the roof, such as constructing a stadium on the top of a teaching building, if there are buildings that need to be protected under the stadium, temporary support frames are often built around the buildings to be protected, and Bailey trusses are installed on the temporary support frames to support the formwork for constructing the stadium.

[0003] Before the stadium is constructed, the Bailey truss can be directly lifted onto the temporary support frame by a crane. However, after the stadium is constructed, the space at the top of the Bailey truss is small, and the boom of the crane cannot reach a high position, that is, the angle between the boom and the horizontal plane cannot be too large. If the angle between the boom and the horizontal plane is small, such as Figure 1 shown, the boom will interfere with the edge of the Bailey truss. Summary of the Utility Model

In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] The utility model discloses a slide rail device for demolishing a Bailey truss with low headroom.

[0030] Referring to Figures 2 to 5 , a slide rail device for demolishing a Bailey truss with low headroom includes a guide rail 31 installed at the bottom of a stadium. The guide rail 31 is fixedly connected to a pre-embedded part reserved at the bottom of the stadium through bolts, and one end of the guide rail 31 extends outside the stadium. A sliding plate 32 is arranged below the guide rail 31. The sliding plate 32 can slide relative to the guide rail 31 through a sliding component 33. A lifting component 34 is installed on the sliding plate 32, and the lifting component 34 is suitable for hoisting items. By reserving a pre-embedded part at the bottom of the stadium, it is convenient to install the guide rail 31. Subsequently, the sliding plate 32 is driven to move relative to the guide rail 31 through the sliding component 33 to drive the lifting component 34 to move, so as to facilitate moving the item to be hoisted outside the bottom of the stadium, and then facilitate the transfer of the item and improve the construction efficiency.

[0031] To improve the stability of the movement of the sliding plate 32, two groups of sliding components 33 are arranged oppositely along the width direction of the slide rail.

[0032] Specifically, the sliding component 33 includes a mounting plate 331, a rotating part 332, and a driving wheel 333. The mounting plate 331 is fixedly connected to the sliding plate 32, the rotating part 332 is fixedly connected to the mounting plate 331, the driving wheel 333 is rotatably connected to the mounting plate 331, a chute 311 is arranged on the guide rail 31, and the driving wheel 333 is suitable for rolling in the chute 311. The output end of the rotating part 332 is coaxially and fixedly connected with a power wheel 334, and the driving wheel 333 is coaxially and fixedly connected with a transmission wheel 338. The power wheel 334 and the transmission wheel 338 are driven through a flexible transmission part 335, so that the rotating part 332 can drive the driving wheel 333 to rotate. The flexible transmission part 335 can be a chain or a synchronous belt. Through the flexible transmission part 335, the load received by the driving wheel 333 can be buffered, and the load transmitted to the output end of the rotating part 332 can be reduced.

[0033] More specifically, a support wheel 336 is rotatably connected to the mounting plate 331, and the support wheel 336 rolls in the chute 311. There are two support wheels 336 on each mounting plate 331, and the two support wheels 336 are arranged oppositely on both sides of the driving wheel 333 to reduce the load borne by the driving wheel 333. An elastic material, which can be a rubber ring, is arranged on the surface of the driving wheel 333. When the driving wheel 333 is working, the support wheel 336 bears most of the load, while the driving wheel 333 bears a small part of the load and remains in a compressed state to ensure the friction between the driving wheel 333 and the bottom of the chute 311, so as to drive the sliding plate 32 to slide relative to the guide rail 31.

[0034] Furthermore, a limiting wheel 337 is rotatably connected to the mounting plate 331. The axis of the limiting wheel 337 is arranged in the vertical direction, and the side wall of the limiting wheel 337 is in contact with the slide rail. A set of limiting wheels 337 is provided on each mounting plate 331, and the two sets of limiting wheels 337 cooperate with each other to assist in positioning the sliding plate 32 relative to the guide rail 31 in the width direction of the guide rail 31, further improving the stability of the sliding plate 32.

[0035] Furthermore, one end of the guide rail 31 is fixedly connected with a baffle plate 312, and the other end is detachably connected with a limiting plate 313 through bolts. The limiting plate 313 is arranged at one end of the guide rail 31 extending outside the bottom of the stadium.

[0036] It should be noted that there are two sets of lifting assemblies 34 arranged opposite to each other in the width direction of the guide rail 31, and the lifting ropes of the two sets of lifting assemblies 34 are located on both sides of the sliding plate 32. The lifting assembly 34 is installed on the top surface of the sliding plate 32, and the highest point of the lifting assembly 34 is lower than the highest surface of the guide rail 31. The lifting assembly 34 includes a crane and a hook connected to the output end of the crane.

[0037] Working principle: By reserving embedded parts at the bottom of the stadium, it is convenient to install the guide rail 31. Subsequently, the sliding assembly 33 is used to drive the sliding plate 32 to move relative to the guide rail 31, so as to drive the lifting assembly 34 to move, thereby facilitating the movement of the item to be lifted outside the bottom of the stadium, and then facilitating the transfer of the item and improving the construction efficiency.

[0038] By arranging the lifting assembly 34 on the top surface of the sliding plate 32 and the highest point of the lifting assembly 34 being lower than the highest surface of the guide rail 31, all components are integrated within a relatively low height range as much as possible, thereby adapting to the narrow space between the item and the bottom of the stadium. The sliding plate 32 is guided and limited by the supporting wheels 336 and the limiting wheels 337, improving the stability and accuracy of the movement of the sliding plate 32.

The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
