Description

Technical Field

[0001] This utility model belongs to the field of civil engineering technology, and in particular relates to a concrete pipe with a pre-embedded hoisting hole for positioning guidance. Background Technology

[0002] Concrete pipes are used for water supply, drainage, rainwater discharge and other infrastructure construction. Due to their pressure resistance, corrosion resistance and adaptability to various climatic conditions, they are widely used. Currently, after installation, concrete pipes are connected end to end. During the installation process, hoisting equipment is used to lift the concrete pipes, and the smaller diameter end of one concrete pipe is inserted into the larger diameter end of another concrete pipe to complete the connection between the two adjacent concrete pipes.

[0003] However, when installing two adjacent concrete pipes, the lack of a positioning and guiding structure for the concrete pipes leads to poor connection stability after installation. Furthermore, the existing technology for hoisting concrete pipes traditionally involves hooking the two ends of the concrete pipe with hooks and using hoisting equipment for lifting. However, this method is prone to stress concentration or slippage, which can cause damage to the pipe or safety accidents, resulting in significant safety hazards.

[0004] To address these issues, we provide a pre-embedded hoisting hole concrete pipe with positioning guidance. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded hoisting hole concrete pipe with positioning guidance. The guide groove and the insertion rod provide guidance during the installation of the concrete pipe body. The connection between the two concrete pipe bodies is achieved through the cooperation of the connecting rod and the protrusion. Furthermore, the hoisting components can improve the stability during hoisting. This solves the problems of existing concrete pipes lacking positioning guidance structure, resulting in poor connection stability after the installation of two concrete pipes. In addition, the existing hoisting method using hoisting equipment is prone to pipe damage or safety accidents due to stress concentration or slippage, which poses a significant safety hazard.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pre-embedded hoisting hole concrete pipe with positioning guidance, comprising a concrete pipe body, a left connecting sleeve fixed inside the left end of the concrete pipe body, a guide groove arranged in a circular array on the inner circumferential wall of the left connecting sleeve, and a connecting rod arranged in a circular array on the left connecting sleeve. A right connecting sleeve that mates with the left connecting sleeve is fixed outside the right end of the concrete pipe body, and an insert rod that mates with the guide groove is fixed in a circular array on the outer circumferential wall of the right side of the right connecting sleeve. Hoisting components are provided on both the left and right sides of the upper end of the concrete pipe body, each hoisting component including a screw fixed to the concrete pipe body, a threaded sleeve with a closed upper end connected to the upper side of the screw, a rotating rod above the screw sleeve, and a lifting ring fixed at the upper end of the rotating rod.

[0008] The present invention is further configured such that the cross-sections of the left connecting sleeve and the right connecting sleeve are both L-shaped, and the right end inside the left connecting sleeve is provided with a sealing gasket that is fixed to the concrete pipe body.

[0009] The present invention is further provided that an insertion hole is provided on the right connecting sleeve corresponding to the location of the connecting rod, and a through groove is provided on the right connecting sleeve corresponding to one side of the insertion hole.

[0010] The present invention is further configured such that a boss is fixedly provided at the left end of the connecting rod, and a protrusion that cooperates with the through groove is fixedly provided at the right end of the outer peripheral wall of the connecting rod.

[0011] The present invention is further configured such that the outer peripheral wall of the right side of the left connecting sleeve is uniformly fixed with protrusions located inside the concrete pipe body, the inner peripheral wall of the right connecting sleeve is fixed with protruding ridges located inside the concrete pipe body, and the inner end of the insertion rod is inserted into the inner peripheral wall of the concrete pipe body.

[0012] The present invention is further configured such that an embedded plate located inside the periphery of the concrete pipe body is fixed at the lower end of the screw, a round rod is symmetrically fixed on the outer periphery of the screw sleeve, and a connecting plate is provided with a clearance fit on the outer side of the rotating rod.

[0013] The present invention is further provided with a baffle fixed to the rotating rod below the connecting plate, and vertical plates that are clearance-fitted with the round rod are fixed on both sides of the lower wall of the baffle.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting a guide groove, insert rod, connecting rod, and protrusion, allows the insert rod on the right connecting sleeve of the hoisted concrete pipe body to move along the guide groove in the installed concrete pipe body during installation. The guide groove and insert rod provide guidance for the installation between the two concrete pipe bodies. After the above process is completed, the connecting rod is inserted into the insertion hole, and then the connecting rod is rotated to drive the protrusion to rotate, so that the left connecting sleeve can be connected to the right connecting sleeve in the adjacent concrete pipe body, thereby improving the stability between the two concrete pipe bodies.

[0016] 2. This utility model sets up a hoisting assembly, in which the screw and the embedded plate are pre-embedded in the concrete pipe body. The screw sleeve is connected to the screw thread by operating the screw thread, and then the hook is hung on the lifting ring. The hoisting equipment works to drive the hoisting assembly to rise, thereby lifting the concrete pipe body to achieve hoisting. Compared with the prior art, by hanging the hook on the lifting ring for hoisting, the hoisting of the concrete pipe body is more stable and improves safety.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present invention. This embodiment provides a pre-embedded hoisting hole concrete pipe with positioning guide, including a concrete pipe body 1, the concrete pipe body 1 including a concrete pipe body 103, a left connecting sleeve 102 fixed inside the left end of the concrete pipe body 103, when the concrete pipe body 1 is connected to an adjacent concrete pipe body 1, a right connecting sleeve 104 is inserted into the interior of the left connecting sleeve 102 in the adjacent concrete pipe body 1, the inner peripheral wall of the left connecting sleeve 102 is provided with a guide groove 102a in a circular array, the left connecting sleeve 102 is provided with a connecting rod 105 in a circular array, the right end of the concrete pipe body 103 is fixed with a right connecting sleeve 104 that cooperates with the left connecting sleeve 102, the outer peripheral wall of the right side of the right connecting sleeve 104 is fixed with an insertion rod 104b that cooperates with the guide groove 102a in a circular array, and the left connecting sleeve 102 is provided with an insertion hole 104c and a through groove 104d that allow the connecting rod 105 and the protrusion 105b to pass through;

[0030] Specifically, the cross-sections of the left connecting sleeve 102 and the right connecting sleeve 104 are both L-shaped. The right end of the left connecting sleeve 102 is provided with a sealing gasket 101 fixed to the concrete pipe body 103. When the two concrete pipe bodies 1 are connected, the right connecting sleeve 104 is inserted into the left connecting sleeve 102 in the adjacent concrete pipe body 1, and the right end of the right connecting sleeve 104 abuts against the sealing gasket 101 in the adjacent concrete pipe body 1 to improve the sealing between the concrete pipe body 1 and the adjacent concrete pipe body 1.

[0031] An insertion hole 104c is provided on the right connecting sleeve 104 corresponding to the location of the connecting rod 105. A through groove 104d is provided on the right connecting sleeve 104 corresponding to one side of the insertion hole 104c. The insertion hole 104c and the through groove 104d are provided so that the connecting rod 105 and the protrusion 105b can pass through.

[0032] A boss 105a is fixedly provided at the left end of the connecting rod 105, and a protrusion 105b that mates with the through groove 104d is fixedly provided at the right end of the outer peripheral wall of the connecting rod 105. When the concrete pipe body 1 is connected to the adjacent concrete pipe body 1, the boss 105a is operated to make the connecting rod 105 pass through and the protrusion 105b pass through the insertion hole 104c and the through groove 104d on the right connecting sleeve 104 respectively. Then, the protrusion 105b is misaligned with the through groove 104d, so that the right connecting sleeve 104 can be stably connected to the left connecting sleeve 102 in the adjacent concrete pipe body 1.

[0033] The outer peripheral wall of the right side of the left connecting sleeve 102 is uniformly provided with protrusions 102b located inside the concrete pipe body 103. The inner peripheral wall of the right connecting sleeve 104 is provided with protrusions 104a located inside the concrete pipe body 103. The protrusions 102b make the left connecting sleeve 102 and the concrete pipe body 103 stably connected. The inner end of the insertion rod 104b is inserted into the inner peripheral wall of the concrete pipe body 103. The protrusions 104a and the insertion rod 104b limit the distance between the right connecting sleeve 104 and the left connecting sleeve 102, so that the right connecting sleeve 104 and the concrete pipe body 103 are stably connected.

[0034] The operation process of this embodiment is as follows: During installation, the hoisting equipment hooks the lifting ring 201a, and the hoisting equipment is operated to rise, driving the concrete pipe body 1 to rise until the concrete pipe body 1 moves to the side of the already installed concrete pipe body 1. At this time, the concrete pipe body 1 to be installed is operated so that the insertion rod 104b in the concrete pipe body 1 to be installed moves along the guide groove 102a of the left connecting sleeve 102 in the already installed concrete pipe body 1, so that the right connecting sleeve 104 in the concrete pipe body 1 to be installed is inserted into the already installed concrete pipe body 1. Inside the left connecting sleeve 102 of the concrete pipe body 1, and with the right wall of the right connecting sleeve 104 of the concrete pipe body 1 to be installed pressed against the sealing gasket 101 of the installed concrete pipe body 1, the operating boss 105a is used to make the connecting rod 105 pass through the right connecting sleeve 104, and then the connecting rod 105 passes through the left connecting sleeve 102 of the adjacent concrete pipe body 1. Finally, the connecting rod 105 is rotated so that the boss 105a and the corresponding protrusion 105b are misaligned, so that a stable connection can be obtained between the two adjacent concrete pipe bodies 1.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: hoisting components 2 are provided on both the left and right sides of the upper end of the concrete pipe body 103. The hoisting components 2 include screws 204 fixed to the concrete pipe body 103. The screws 204 are embedded in the concrete pipe body 103. The upper side of the screws 204 is externally threaded with a screw sleeve 203 with the upper end closed. The screw sleeve 203 and the screws 204 are detachable, so that the screw sleeve 203 can be reused. A rotating rod 201 is provided above the screw sleeve 203. A lifting ring 201a is fixed at the upper end of the rotating rod 201. When the hook hooks the lifting ring 201a, the concrete pipe body 1 can be hoisted using hoisting equipment.

[0037] Specifically, the lower end of the screw 204 is fixed with an embedded plate 204a located inside the periphery of the concrete pipe body 103, the outer periphery of the screw sleeve 203 is symmetrically fixed with a round rod 203a, and the outer clearance of the rotating rod 201 is fitted with a connecting plate 202.

[0038] Below the connecting plate 202, there is a baffle 201b fixed to the rotating rod 201. Both sides of the lower wall of the baffle 201b are fixed with vertical plates 202a that are in clearance fit with the round rod 203a. The vertical plates 202a and the round rod 203a can rotate relative to each other.

[0039] The operation process of this embodiment is as follows: the pre-embedded plate 204a and the screw 204 are pre-embedded in the concrete pipe body 103. When the concrete pipe body 1 is hoisted, the operating sleeve 203 is screwed onto the outside of the corresponding screw 204. Then, the operating hook is hung on the lifting ring 201a. The hoisting equipment is used to raise the hook, thereby raising the lifting ring 201a, which in turn raises the hoisting assembly 2, and finally makes the concrete pipe body 1 move to realize the transportation of the concrete pipe body 1.
