Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pipe hoisting technology, specifically relating to a concrete pipe tilting hoist. Background Technology
[0002] Because the joints of concrete drainage pipes are made of concrete, disc lifters cannot be used to hoist the pipes. The traditional method is to use clamp lifters. However, clamp lifters also have their drawbacks:
[0003] (1) This hoisting equipment requires a set of clamps and lifting devices to be made for each specification of pipe, which greatly increases the company's costs and space occupation, and has a very small scope of application;
[0004] (2) The clamps of this hoisting equipment are made of 6mm patterned plate. After a period of use, the pattern wears down and is prone to slipping during hoisting, causing the pipe to fall, which poses a great safety hazard.
[0005] (3) The locking mechanism of this hoisting equipment is bolt locking. In order to ensure the tightness of the clamp, the bolts must be tightened very tightly. The service life of the bolts is limited, and frequent replacement of bolts increases the cost of use. Utility Model Content
[0006] The purpose of this utility model is to provide a concrete pipe tilting and lifting tool to solve the problem of the limited applicability of existing concrete drainage pipe lifting tools.
[0007] The technical solution adopted in this utility model is as follows:
[0008] A concrete pipe tilting and lifting device includes two lifting holes pre-embedded on the outer circumference of the pipe, the two lifting holes being arranged opposite each other with their axes aligned on the same straight line, and a lifting disc. The lifting disc is detachably connected to the lifting holes via fastening components. The lifting disc includes a lifting base that fits tightly against the lifting holes and a cover plate mounted on the lifting base. The cover plate has a first mounting hole at its center for mounting the fastening components, and the lifting base has a second mounting hole at its center for mounting the fastening components. A bearing groove is provided on the lifting base above the second mounting hole, and a first sliding bearing is installed in the bearing groove. The lifting base is equipped with a first lifting lug and a lifting beam. Two second lifting lugs are symmetrically installed on the upper surface of the lifting beam relative to the midpoint of the beam's length direction. Two positioning plates are symmetrically installed on the lower surface of the lifting beam relative to the midpoint of the beam's length direction. The positioning plates have positioning connection holes and are equipped with an upper wire rope and a lower wire rope. One end of the lower wire rope is fixed to the first lifting lug, and the other end is fixed to the positioning connection hole. One end of the upper wire rope is fixed to the second lifting lug, and the other end is fixed to the working end of the crane.
[0009] Furthermore, the hoisting hole includes a pipe body, a cap nut is provided at the bottom end of the hole of the pipe body, and a reinforcing plate is provided at the opening end of the hole of the pipe body.
[0010] Furthermore, the fastening assembly includes a lifting pin and a fastening bolt. The lifting pin passes through the first mounting hole, the first sliding bearing, and the second mounting hole in sequence and extends into the tube body to abut against the bottom end of the hole in the tube body. The lifting pin has a bolt assembly hole, and the fastening bolt passes through the bolt assembly hole and is threadedly connected to the cap nut.
[0011] Furthermore, a second sliding bearing is also fitted onto the lifting pin, the second sliding bearing being located between the end cap of the lifting pin and the upper surface of the cover plate.
[0012] Furthermore, the cover plate is detachably mounted on the hanger using mounting bolts.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. In this utility model, two symmetrically arranged lifting holes are pre-embedded during pipe forming. A fastening assembly connects the lifting disc to the lifting holes. A lower steel wire rope connects the first lifting lug on the lifting disc's support to the positioning connection hole below the lifting beam, thus connecting the lifting disc to the lifting beam. An upper steel wire rope connects the second lifting support above the lifting beam to the working end of the crane. Through the cooperation of the lifting holes, lifting disc, lifting beam, and upper and lower steel wire ropes, the concrete pipe is lifted. This lifting device has a simple structure, is easy to manufacture, has a low overall cost, and a wide range of applications. One set of lifting devices can cover the lifting of all pipe specifications. Only a positioning connection hole matching the outer diameter of the pipe needs to be opened at the corresponding position on the positioning plate below the lifting beam, greatly reducing enterprise costs and site occupation area, and effectively solving the problem of the limited applicability of existing concrete drainage pipe lifting devices.
[0015] 2. In this utility model, sliding bearings are installed between the lifting pin and the cover plate, and between the cover plate and the lifting seat. The pipe body can be flipped while the lifting is being carried out, eliminating the need for a special pipe flipping device and further reducing the company's operating costs.
[0016] 3. In this utility model, the lifting pin passes through the second sliding bearing, the first mounting hole, the first sliding bearing, the second mounting hole in sequence, and is inserted into the lifting hole. At the same time, the fastening bolt passes through the bolt assembly hole and is threadedly connected to the cap nut to prevent the lifting pin from slipping out during lifting, which plays a safety role and improves the safety of the lifting device.

[0032] Refer to the instruction manual. Figure 1 -Instruction manual included Figure 7 ,
[0033] A concrete pipe tilting and lifting device includes two lifting holes pre-embedded on the outer circumference of the pipe, the two lifting holes being arranged opposite each other with their axes aligned on the same straight line, and a lifting disc. The lifting disc is detachably connected to the lifting holes via fastening components. The lifting disc includes a lifting base that fits tightly against the lifting holes and a cover plate mounted on the lifting base. The cover plate has a first mounting hole at its center for mounting the fastening components, and the lifting base has a second mounting hole at its center for mounting the fastening components. A bearing groove is provided on the lifting base above the second mounting hole, and a first sliding bearing is installed in the bearing groove. The lifting base is equipped with a first lifting lug and a lifting beam. Two second lifting lugs are symmetrically installed on the upper surface of the lifting beam relative to the midpoint of the beam's length direction. Two positioning plates are symmetrically installed on the lower surface of the lifting beam relative to the midpoint of the beam's length direction. The positioning plates have positioning connection holes and are equipped with an upper wire rope and a lower wire rope. One end of the lower wire rope is fixed to the first lifting lug, and the other end is fixed to the positioning connection hole. One end of the upper wire rope is fixed to the second lifting lug, and the other end is fixed to the working end of the crane.
[0034] In this embodiment, two symmetrically arranged lifting holes are pre-embedded during pipe forming. A fastening assembly connects the lifting disc to these holes. A lower steel wire rope connects the first lifting lug on the lifting disc's support to the positioning connection hole below the lifting beam, thus connecting the lifting disc to the beam. An upper steel wire rope connects the second lifting support above the beam to the crane's working end. Through the coordination of the lifting holes, lifting disc, lifting beam, and upper and lower steel wire ropes, the concrete pipe is lifted. This lifting device has a simple structure, is easy to manufacture, has a low overall cost, and a wide range of applications. One set of lifting devices can cover the lifting of all pipe specifications. Only a positioning connection hole matching the pipe's outer diameter needs to be opened at the corresponding position on the positioning plate below the beam, significantly reducing enterprise costs and site space requirements, effectively solving the problem of limited applicability of existing concrete drainage pipe lifting devices.
[0035] In a preferred embodiment, the hoisting hole includes a pipe body, with a cap nut at the bottom end of the hole and a reinforcing plate at the opening end. The cap nut is a non-slip nut.
[0036] In this embodiment, the reinforcing plate can improve the structural stability of the hoisting hole and also has a water-stopping effect.
[0037] Specifically, preferably, the two lifting holes are symmetrical with respect to the axis of the pipe's center of gravity. Additionally, U-shaped lifting rings are provided on the first lifting lug, the second lifting lug, and the positioning connection hole for connection to the corresponding wire rope.
[0038] In a preferred embodiment, the fastening assembly includes a lifting pin and a fastening bolt. The lifting pin passes sequentially through a first mounting hole, a first sliding bearing, and a second mounting hole, extending into the tube body and abutting against the bottom end of the hole in the tube body. A bolt assembly hole is provided within the lifting pin, and the fastening bolt passes through the bolt assembly hole and is threadedly connected to a cap nut. Additionally, a second sliding bearing is fitted onto the lifting pin, located between the end cap of the lifting pin and the upper surface of the cover plate.
[0039] In this embodiment, the lifting pin passes sequentially through the second sliding bearing, the first mounting hole, the second mounting hole, and is inserted into the lifting hole. Simultaneously, the fastening bolt passes through the bolt assembly hole and is threadedly connected to the cap nut to prevent the lifting pin from slipping out during lifting, providing a safety feature and improving the safety of the lifting device. Furthermore, the second sliding bearing between the end cap of the lifting pin and the cover plate acts as a planar bearing, bearing the radial force. The first sliding bearing installed between the cover plate and the lifting seat acts as a radial bearing, bearing the vertical gravity. When the pipe is lifted to a height greater than half its outer diameter from the ground, applying a slight external force to one end of the pipe allows it to rotate 90° through the sliding of the radial bearing and the planar bearing, enabling a switch from vertical to horizontal lifting. This simultaneous lifting and pipe rotation meets the needs of decoration and pipeline installation, eliminating the need for specialized pipe-flipping equipment and further reducing operating costs for the enterprise.
[0040] In a preferred embodiment, the cover plate is detachably mounted on the hanger using mounting bolts.
[0041] In this embodiment, the cover plate is detachably installed on the lifting base, which facilitates the removal of the cover plate to replace or maintain the first sliding bearing, and also facilitates the quick disassembly of the lifting pin and the lifting disc as a whole.
[0042] The above description constitutes an embodiment of this utility model. The foregoing descriptions are preferred embodiments of this utility model. Unless there is a clear contradiction between the preferred embodiments or a premise based on a particular preferred embodiment, the preferred embodiments can be arbitrarily combined and used. The embodiments and specific parameters described are merely for clearly illustrating the verification process of the utility model and are not intended to limit the patent protection scope of this utility model. The patent protection scope of this utility model is still determined by its claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model should also be included within the protection scope of this utility model.
