Description

Technical Field

[0001] The invention relates to a cable conduit, and in particular to a production process of a concrete type cable conduit. Background Art

[0002] like Figure 1 As shown, the concrete cable conduit includes: a skeleton, an inner tube and a concrete layer. At least three inner tubes are installed in the skeleton, and the inner tubes are for cables to pass through. A concrete layer is poured outside the skeleton and the inner tubes. The skeleton includes: connecting ribs, spirally wound ribs and inner grids. There are at least 4 connecting ribs, all of which are parallel to each other. All connecting ribs are fixed to the spirally wound ribs. All connecting ribs are fixed with inner grids. There are at least three inner grids, and the inner tube is inserted into the inner grid. There is a gap between the inner wall of the inner hole of the inner grid and the inner tube.

Furthermore, since there are multiple inner tubes, it is difficult to align all the inner tubes with the second side mold at the same time when the second side mold is pushed, so a support rod is provided, and the support rod is first extended into the inner tube before the second side mold and the first side mold are buckled. Although there are multiple support rods, the support rods can be moved one by one, so that each support rod is positioned to an inner tube, which is convenient for positioning the inner tube, and then it is convenient to push the first side mold and the second side mold to the buckled position, and the inner tube is extended into the first side mold and the second side mold, which improves the efficiency of buckling the first side mold and the second side mold.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0036] like Figures 1 to 3 As shown, the present invention discloses a concrete cable conduit production process, comprising the following steps:

[0037] S1. Prepare the cable tube arrangement mold, which includes: a bottom mold 1, a top mold (not shown), a first side mold 2, a second side mold 3, a support base frame 4 and a support rod 5. The bottom mold 1, the first side mold 2 and the second side mold 3 are installed on the support base frame 4. The bottom mold 1 is a U-shaped trough structure. The bottom mold 1 opens upward. The bottom mold 1 is used to place the horizontal skeleton and inner tube 62 in the concrete type cable tube arrangement. One side of the bottom mold 1 is blocked by the first side mold 2, and the other side of the bottom mold 1 is blocked by the second side mold 3. A support rod 5 is installed next to the first side mold 2. The support rod 5 can move in the X direction relative to the support base frame 4. The support rod 5 is used to be inserted into the inner hole of the inner tube 62. The first side mold 2 and the second side mold 3 are both provided with a first insertion hole 21 and a second insertion hole 22. The first insertion hole 21 is for the inner tube 62 to be inserted, and the second insertion hole 22 is for the connecting rib 611 in the skeleton to be inserted;

[0038] S2, inserting the inner tube 62 of the concrete cable conduit into the frame;

[0039] S3, placing the inner tube 62 and the frame of the concrete cable conduit into the bottom mold 1, and the axis of the inner tube 62 is parallel to the X direction;

[0040] S4, pushing the support rod 5 through the first side mold 2, and the support rod 5 extends into the inner tube 62;

[0041] S5, manually lift the skeleton so that the skeleton is suspended in the bottom mold 1;

[0042] S6, push the second side mold 3, so that the connecting rib 611 in the frame extends into the second insertion hole 22 of the second side mold 3, the inner tube 62 extends into the first insertion hole 21 of the second side mold 3, and the second side mold 3 blocks one side of the bottom mold 1;

[0043] S7, push the first side mold 2, so that the connecting rib 611 in the frame extends into the second insertion hole 22 of the first side mold 2, the inner tube 62 extends into the first insertion hole 21 of the first side mold 2, and the first side mold 2 blocks the other side of the bottom mold 1;

[0044] S8, pouring concrete into the bottom mold 1 and ensuring that the top surface of the concrete is flat;

[0045] S9, buckle the top of the bottom mold 1 with the top mold;

[0046] S10, solidifies to form a concrete type cable conduit semi-finished product.

[0047] A guide seat 40 is mounted on the support chassis 4, and the guide seat 40 guides the movement of the support rod 5 in the X direction. The guide seat 40 guides the support rod 5 and also has the function of supporting the guide rod to prevent the support rod 5 from being pried at will when the support rod 5 supports the inner tube 62.

[0048] The second side mold 3 includes: a second support mold 31, a second end mold 32 and a second guide rotating rod 33. The first insertion hole 21 and the second insertion hole 22 are provided on one side of the second support mold 31. The other side of the second support mold 31 is blocked and extended to form the second end mold 32. The second end mold 32 is a U-shaped structure with the opening facing upward. The second end mold 32 and the second support mold 31 fix the second guide rotating rod 33. The second guide rotating rod 33 extends into the guide groove provided in the support base frame 4, and the second guide rotating rod 33 can rotate in the guide groove. It is achieved that when rotating around the second guide rotating rod 33, the second support mold 31 and the second end mold 32 can be switched to be close to the bottom mold 1, thereby achieving different effects.

[0049] The first side mold 2 includes: a first support mold 23, a first end mold 24, a first guide rotating rod 25, a lifting frame 26 and an intermediate isolation block 27. The first support mold 23 is penetrated by the first insertion hole 21 and the second insertion hole 22. One side of the first support mold 23 extends to form a first end mold 24. The first end mold 24 is a U-shaped structure with an opening facing upward. The first support mold 23 extends into the bottom mold 1. The first end mold 24 fixes the first guide rotating rod 25. The first guide rotating rod 25 extends into the guide groove provided in the support bottom frame 4. The first guide rotating rod 25 can rotate in the guide groove. A lifting frame 26 is installed in the first end mold 24, and the lifting frame 26 is fixed with an intermediate isolation block 27 located in the middle of the second end mold 32. There is an annular gap between the intermediate isolation block 27 and the inner wall of the first end mold 24, and the annular gap is a U-shaped structure. Lifting seats 41 are fixed on both sides of the lifting frame 26 of the supporting base frame 4. When the first supporting mold 23 is located on the side of the first end mold 24 close to the bottom mold 1, the lifting seat 41 is used to lift the lifting frame 26, and when the first supporting mold 23 is located on the side of the first end mold 24 away from the bottom mold 1, the lifting seat 41 does not block the lifting frame 26 from being lowered.

[0050] Since the semi-finished product obtained after using the second support mold 31 and the first support mold 23 has a part of the skeleton's connecting ribs 611 and the inner tube 62 exposed from the end, the second end mold 32 and the first end mold 24 are set up. The end can be processed into the required shape by casting twice, and the two castings are connected with the skeleton, which reduces the probability of breakage.

[0051] The lifting frame 26 extends to form a first supporting leg 28 and a second supporting leg 29, the first supporting leg 28 and the second supporting leg 29 are located in the Y direction, the distance between the first supporting leg 28 and the middle isolation block 27 is D1, the distance between the second supporting leg 29 and the middle isolation block 27 is D2, D2>D1, and the two lifting seats 41 are asymmetrically arranged on the supporting base frame 4. The following functions are realized: when the first supporting mold 23 is located on the side of the first end mold 24 close to the bottom mold 1, the lifting seat 41 is used to lift the lifting frame 26, and when the first supporting mold 23 is located on the side of the first end mold 24 away from the bottom mold 1, the lifting seat 41 does not block the lifting frame 26 from being lowered. Since the first support mold 23 and the first end mold 24 can be switched to be close to the bottom mold 1, the distances between the first support leg 28 and the second support leg 29 and the middle isolation block 27 are different, so that when the first support mold 23 blocks the bottom mold 1, it is supported by the lifting seat 41, avoiding the movement of the support rod 5 being blocked by the middle isolation block 27 and the lifting frame 26, ensuring smooth movement of the support rod 5. When the first end mold 24 is needed to block the bottom mold 1, it has been rotated to a position where the first support leg 28 and the second support leg 29 cannot be supported by the lifting seat 41, thereby ensuring that the middle isolation block can be lowered to a state located inside the first end mold 24. At this time, the support rod 5 is not needed, and the first insertion hole 21 through which the support rod 5 passes can be blocked to prevent concrete from entering.

[0052] In step S6, the second supporting mold 31 is located between the second end mold 32 and the bottom mold 1, and in step S7, the first supporting mold 23 is located between the first end mold 24 and the bottom mold 1. After step S10, the following steps are performed:

[0053] S11, pulling the first side mold 2 and the second side mold 3 away from the frame and the inner tube 62, and at the same time making the support rod 5 away from the first side mold 2;

[0054] S12, rotating the first side mold 2 and the second side mold 3, so that the second end mold 32 is located between the second support mold 31 and the bottom mold 1, the first end mold 24 is located between the first support mold 23 and the bottom mold 1, and the first support foot 28 and the second support foot 29 are not supported by the lifting seat 41, and the middle isolation block 27 is located in the first end mold 24;

[0055] S13, moving the first side mold 2 and the second side mold 3, the first end mold 24 is buckled with one side of the bottom mold 1, and the second end mold 32 is buckled with the other side of the bottom mold 1;

[0056] S14, pouring concrete from the top of the first end mold 24, and pouring concrete from the top of the second end mold 32;

[0057] S15, solidification to form a finished concrete cable conduit. The first end mold 24 and the second end mold 32 are used to cast end blocks at both ends of the semi-finished product, and the finished product is finally formed. The leaked connecting ribs 611 and inner tube 62 of the semi-finished product are also covered to ensure integrity. The end blocks are cast when the semi-finished product has been formed but has not completely dried, so that the connection is more firm.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
