[0003] In the existing construction, no special tool is used for hoisting the concrete conduit, and a cable is generally directly wound under the annular boss at the end of the concrete conduit, since the outer diameter of the annular boss is larger than the outer diameter of the body of the concrete conduit, the cable can be fixed there, however, this method is not safe and stable during hoisting of the concrete conduit. Figure 6 The existing arc-shaped ring structure is shown in the figure, the cable is hoisted after being punched into the arc-shaped ring structure at both end faces, this improvement can increase stability during hoisting, the cable is clamped under the annular boss of the concrete conduit in cooperation with the arc-shaped ring structure during lifting of the concrete conduit, which to some extent avoids the trouble of winding and fixing the cable on the concrete conduit and increases hoisting safety, but the concrete conduit is moved in an inclined state during hoisting, and the clamping action of the arc-shaped ring structure on one side of the concrete conduit is prone to wear the side wall of the concrete conduit due to the tightening action of the cable during hoisting, especially when the hoisted concrete conduit is sequentially sealed and connected for construction, the vertical alignment of the upper and lower conduits is inconvenient.

[0004] Based on this, the application provides a special tool for hoisting a concrete conduit.

[0030] In order to clearly explain the technical features of the scheme, the utility model is described in detail below through specific implementation mode, combined with the drawings.

[0031] ​In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0032] Referring to Figures 1-5 The embodiment discloses the structure of the special tool for hoisting concrete pipes and the reference of the use state thereof, specifically, the special tool for hoisting concrete pipes comprises two hoop members fixedly assembled together, the hoop member comprises a semicircular sheet body 1, a vertical plate 2 is arranged on the top surface of the two ends of the semicircular sheet body, and a horizontal spacing is left between the side of the vertical plate close to the arc-shaped inner wall of the semicircular sheet body and the arc-shaped inner wall of the semicircular sheet body, a semicircular ring range (such as Figure 3 the surface of the semicircular sheet body with the horizontal spacing as the width forms a supporting surface 3 for supporting the annular boss arranged at the end of the concrete pipe. Hoisting holes 201 are arranged on the two vertical plates of each hoop member, and an assembly hole 202 is arranged below the hoisting hole of one of the vertical plates; after the two hoop members are assembled at the corresponding semicircular sheet bodies, the vertical plates aligned with each other are fixed through a clip 4, and the circular opening formed by the closed semicircular sheet bodies is adapted to the outer diameter of the concrete pipe and limits the annular boss at the end of the concrete pipe.

[0033] The clip 4 comprises a first clamping plate 401 and a second clamping plate 402 connected with the first clamping plate, a pin hole 403 is arranged on the first clamping plate corresponding to the assembly hole 202, and the second clamping plate is arranged below the pin hole; the first and second clamping plates jointly enclose an assembly space for accommodating the adjacent vertical plates of the two hoop members. The horizontal spacing of the space enclosed by the first and second clamping plates is slightly greater than the thickness of the adjacent vertical plates of the two hoop members assembled together, so that the two vertical plates are gap-fitted with the clip outside the two vertical plates. The clip 4 is assembled and fixed to the two hoop members through a pin 5 sequentially arranged in the pin hole 403 and the assembly hole in the vertical plate corresponding to the pin hole 403.

[0034] The outer edges of the two ends of the semicircular sheet body 1 and the top end of the vertical plate 2 are all arranged in a chamfered manner.

[0035] In use, the concrete conduit hoisting special tool can be directly assembled on the outer wall of the concrete conduit, and is limited by the annular boss at the end of the concrete conduit, connected with the cable 6 through the special tool to realize the hoisting and moving of the concrete conduit. Specifically, the two hoop members of the special tool are assembled around the annular boss of the concrete conduit on the side wall of the concrete conduit, at this time, the two semicircular pieces 1 surround the outer wall of the concrete conduit, the supporting surfaces 3 of the two hoop members cooperatively form an annular supporting surface, the annular supporting surface is in contact with the bottom surface of the annular boss of the concrete conduit, and the adjacent vertical plates of the two hoop members are fixed together by the clamps 4. When hoisting is needed, the cable 6 is wound around the hoisting holes 202 aligned on the two groups of vertical plates to hoist and move the concrete conduit. Due to the effective cooperation between the structure and the concrete conduit, the concrete conduit is gradually lifted and kept in a vertical state during hoisting and moving, which facilitates the fixation of the concrete conduit in subsequent construction and facilitates the sealing connection construction of the upper and lower concrete conduits.

[0036] Through the use of the concrete conduit hoisting special tool, compared with the existing direct cable winding on the annular boss of the concrete conduit for hoisting or the hoisting tool for the arc-shaped piece ring of the fixed concrete conduit for the cable to pass through (see Figure 6 ), the problems of unstable and inconvenient subsequent installation and construction of the concrete conduit during hoisting are better avoided; on the other hand, the wear of the outer wall of the concrete conduit caused by the gravity center of the cable is also avoided; and due to the detachable assembly structure of the concrete conduit hoisting special tool, the assembly and hoisting can be more convenient and faster, and the step of adjusting the cable to separate from the concrete conduit after the arc-shaped piece ring used for hoisting is completed is omitted. After hoisting is completed, the worker rotates the two clamps 4 outward and upward, separates the second clamping plate 402 of each clamp from the corresponding vertical plate, separates the two hoop members, separates the special tool from the concrete conduit which has been hoisted, and continues to be used on another concrete conduit which needs to be hoisted.

[0037] It should be understood that the annular boss on the concrete conduit mentioned in the utility model is a conventional structure of the existing concrete conduit, which is generally provided on the outer side of the two ends of the concrete conduit and has an outer diameter greater than the outer diameter of the pipe body of the concrete conduit.

[0038] It should be noted that the terms "first", "second", and the like in the specification and claims of the utility model and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein.

[0039] The above merely describes some embodiments of the present application, and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
