Description

Technical Field

[0001] The utility model relates to the field of underground cable conduit molds, in particular to a countersunk head lifting ear forming device for an underground cable conduit. Background Art

[0002] In the process of forming the underground cable conduit, the frame and the casing are often fixed in the mold, and then concrete is poured into the mold. After the concrete is formed, the mold is separated from the underground cable. In the process of lifting the underground cable conduit, the lifting lug needs to be installed;

[0003] Existing lifting ears often protrude from the surface of the underground cable duct, but such underground cable ducts cannot be stacked up and down due to the influence of the lifting ears;

[0004] In summary, how to set the lifting ear countersunk head in the underground cable duct to facilitate the upper and lower stacking of two underground cable ducts has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to set the lifting lug countersunk head in the underground cable conduit;

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model is a device for forming a countersunk lifting ear of an underground cable conduit, comprising: a retaining portion, wherein the middle portion has a cavity; a notch for inserting the lifting ear is opened upwardly along the bottom of the retaining portion, and the notch is communicated with the cavity;

[0008] In this solution, the frame and the lifting ear are welded in advance to ensure that the top of the lifting ear does not exceed the mold surface. The enclosure is inserted into the top of the lifting ear through the slot. When the concrete is poured, the top of the lifting ear is blocked by the enclosure and the concrete will not invade the cavity. The top of the lifting ear in the cavity will not be covered by the concrete. After the concrete solidifies, the enclosure is lifted up so that there is a gap between the lifting ear and the nearby concrete. The lifting ear is countersunk in the underground cable duct to facilitate the upper and lower stacking of two underground cable ducts.

[0009] In order to facilitate the carrying of the enclosure, the utility model adopts a hand-held portion provided on the top of the enclosure; the hand-held portion is an arc-shaped rod;

[0010] In this solution, the enclosure part can be separated from the concrete by holding the arc rod and lifting the arc rod.

[0011] During the concrete pouring process, the enclosure part floats up due to the buoyancy of the concrete, and the notch is separated from the lifting ear. In order to limit the floating of the enclosure part, the utility model adopts a sleeve ring, which is sleeved on the arc rod; a hook, the top of which is fixedly connected to the sleeve ring, and the bottom of which is hooked with a lifting ear;

[0012] The hook is set at the lifting ear, and the hook is connected to the arc rod through a ring. In this way, during the floating of the enclosure part, the hook is set with the lifting ear to limit the floating of the enclosure part.

[0013] In order to facilitate the separation of the enclosure part from the concrete after solidification, the utility model adopts the method of gradually reducing the horizontal cross section of the enclosure part from bottom to top;

[0014] In this way, the cross-sectional area gradually decreases from top to bottom, and the contact area with the concrete gradually decreases from top to bottom, making it easier for the enclosure to separate from the concrete after solidification.

[0015] In this solution, when the operator forgets to match the lifting lugs with the enclosure before pouring concrete, the utility model uses the arc-shaped surfaces on both sides of the enclosure as guides;

[0016] The guiding arc surface is provided, so that the enclosure part can be inserted into the concrete with less effort, the concrete can be pushed aside, and the groove can be matched with the lifting ear.

[0017] The beneficial effects of the utility model: the utility model is a device for forming countersunk lifting ears of underground cable ducts. The frame and the lifting ears are welded in advance. It is necessary to ensure that the top of the lifting ear does not exceed the surface of the mold. The enclosure part is inserted into the top of the lifting ear through the slot. When concrete is poured, the top of the lifting ear is blocked by the enclosure part, and the concrete will not invade into the cavity. The top of the lifting ear in the cavity will not be covered by concrete. After the concrete solidifies, the enclosure part is lifted up, so that there is a gap between the lifting ear and the nearby concrete figure. The lifting ear is countersunk installed in the underground cable duct, which is convenient for the upper and lower stacking of two underground cable ducts. BRIEF DESCRIPTION OF THE DRAWINGS

In order to limit the floating of the enclosure part, the utility model adopts a collar 6, which is sleeved on the arc rod 5; a hook 7, the top of which is fixedly connected to the collar 6, and the bottom of which is hooked with a lifting ear 3;

[0028] The hook is set at the lifting ear, and the hook is connected to the arc rod through a ring. In this way, during the floating of the enclosure part, the hook is set with the lifting ear to limit the floating of the enclosure part.

[0029] like Figure 1-2 As shown, in order to facilitate the separation of the enclosure part from the concrete after solidification, the utility model adopts that the horizontal cross section of the enclosure part 1 gradually decreases from bottom to top;

[0030] In this way, the cross-sectional area gradually decreases from top to bottom, and the contact area with the concrete gradually decreases from top to bottom, making it easier for the enclosure to separate from the concrete after solidification.
