Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for hoisting during water conservancy engineering construction. Background Technology

[0002] Concrete well pipes are precast concrete pipes widely used in water wells and drainage projects. They are characterized by high strength, good durability, and low cost in water conservancy projects. Their physical specifications are generally: diameter 200mm–1200mm, standard section length 1m–3m, and wall thickness generally 30mm–100mm.

[0003] However, concrete pipes also have their disadvantages. For example, the pipes are heavy and difficult to transport, handle and hoist. Therefore, special machinery is needed to assist them. Taking the hoisting of concrete pipes as an example, the commonly used hoisting scheme is a combination of hangers and wire ropes, which is hoisted by binding. This hoisting mechanism cannot be used for the vertical hoisting of pipes.

[0004] For example, CN202411704142.6 discloses a pipe hoisting device and method, which includes a hanger, hoisting ropes, a clamping mechanism, a winding mechanism, and a connecting mechanism. Multiple hoisting ropes are mounted on the hanger. The clamping mechanism is mounted on the hoisting ropes and used to clamp the pipe. The winding mechanism is mounted on the hanger and used to wind or unwind the hoisting ropes. The connecting mechanism is mounted on the hanger and used to connect to the hook of the hoisting equipment. This equipment can only be used for horizontal pipe hoisting and cannot be used for vertical hoisting. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for hoisting water conservancy pipelines. This device is designed to solve the problem of a lack of specialized equipment for hoisting and installing concrete pipelines during the vertical installation process in existing water conservancy projects, and aims to improve the installation efficiency of precast concrete pipelines.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A hydraulic pipeline hoisting auxiliary device includes a screw, a guide mechanism, and a support mechanism. The screw's top end is a hoisting section. In the hoisting state, the support mechanism and guide mechanism are installed on the screw from top to bottom. The guide mechanism includes a sleeve I, a damping cylinder, a support rod I, and a roller. Two sleeves I are installed on the screw, one above the other. One end of the support rod I is hinged to the lower sleeve I, and the other end is fitted with a roller. One end of the damping cylinder is hinged to the upper sleeve I, and the other end is hinged to the middle section of the support rod I. The hoisting mechanism includes a sleeve II, a hydraulic cylinder, a support rod II, and a chuck. Two sleeves II are installed on the screw, one above the other. The lower end of the support rod II is hinged to the lower sleeve II, and the other end is fitted with a chuck. One end of the hydraulic cylinder is hinged to the upper sleeve II, and the other end is hinged to the middle section of the support rod II.

[0008] Furthermore, the claw is composed of a metal block and an anti-slip material layer, and the anti-slip material layer is bonded to the metal block.

[0009] Furthermore, the anti-slip material layer is a wear-resistant rubber layer.

[0010] Furthermore, the bonding surface between the wear-resistant rubber layer and the metal block has an interlocking structure.

[0011] Furthermore, the sleeve I has an internal thread and is screwed onto the screw rod by means of threaded engagement, and a nut I is provided on one or both sides of the sleeve I; the sleeve II has an internal thread and is screwed onto the screw rod by means of threaded engagement, and a nut II is provided on one or both sides of the sleeve II.

[0012] Furthermore, there are four support rods I and four damping cylinders, which are arranged at 90-degree angles to each other to form four support structures.

[0013] Furthermore, the guiding mechanism has four sets of damping cylinders and support rod I.

[0014] Furthermore, the supporting and lifting mechanism has four sets of hydraulic cylinders and support rod II.

[0015] Furthermore, the guiding mechanism and the prefabricated pipe below are in a guiding sliding fit.

[0016] Furthermore, the supporting and lifting mechanism and the prefabricated pipe to be installed are internally supported and expanded.

[0017] The beneficial effects of this utility model are:

[0018] This device enables rapid installation of pipelines through a support and lifting mechanism. During the installation process, only the hydraulic cylinder needs to be filled with oil and depressurized to achieve automatic gripping and release, making it a semi-automatic lifting device.

[0019] This device enables automatic alignment between pipes during the prefabricated pipe installation process, improving the concentricity of the pipe installation and saving time and effort compared to traditional installation methods. Attached Figure Description

[0030] This embodiment introduces a hoisting auxiliary device, or auxiliary tool, for precast concrete pipes.

[0031] The device includes a screw 100, a guide mechanism 200, and a lifting mechanism 300. The guide mechanism 200 is used for guiding and sliding engagement with the prefabricated pipe below, and the lifting mechanism 300 is used for internal expansion engagement with the prefabricated pipe to be installed. Lifting equipment is used at the top for hoisting. See the attached instruction manual for details. Figure 1 To be continued Figure 5 A detailed explanation will be provided.

[0032] The screw 100 is a long screw with a length of not less than 1 meter and a diameter of not less than φ20 mm to ensure sufficient tensile strength. Theoretically, the larger the specification of the prefabricated pipe, the larger the screw will be. A hanging ring 110 is provided at the apex of the length direction of the screw. The hanging ring is a circular ring and is welded to the top of the screw.

[0033] Ideally, the hanging ring 110 is welded to the nut, which is screwed onto the top of the screw and welded for auxiliary fixation. During construction, a wire rope is threaded through the hanging ring and fixed to the hook of the hoisting machinery to complete the hoisting of the screw.

[0034] The guiding mechanism 200 includes a sleeve I 210, a damping cylinder 220, a support rod I 230, and a roller 240. Two sleeves I 210 are mounted on the screw 100, one above the other. Specifically, each sleeve I 210 has an internal thread and is screwed onto the screw via a threaded connection. Nuts I 211 are used to determine the position of each sleeve I 210 on one or both sides. Four sets of hinged mounting slots are provided on the outer side of each sleeve I 210 for hinged mounting of the support rod I 230 or the damping cylinder 220. The support rod I 230 is hinged to the lower sleeve I, with its lower end hinged to the sleeve I. The roller 240 is mounted on the upper end of the support rod I via an axle, meaning the roller is mounted at the top of the support rod I. The support rod I 230 is inclined, and a hinge hole is provided in the middle section of the support rod I for the movable connection of the damping cylinder, that is, hinged installation. The upper end of the aforementioned damping cylinder 220 is hinged to the upper sleeve I, and the other end of the damping cylinder, that is, the lower end, is hinged to the hinge hole in the middle section of the support rod I.

[0035] The aforementioned support rod I230 and damping cylinder 220 are four in number and arranged at a 90-degree angle to each other to form four support structures. These support structures are elastic supports, and the elastic elements are the aforementioned damping cylinders.

[0036] The lifting mechanism 300 includes a sleeve II 310, a hydraulic cylinder 320, a support rod II 330, and a chuck 340. Two sleeves II 310 are mounted on the screw rod 100, one above the other. Specifically, each sleeve II has an internal thread and is screwed onto the screw rod via a threaded connection. Nuts II 311 are used to determine the position of each sleeve II 310 on one or both sides. Four sets of hinged mounting slots are provided on the outer side of each sleeve II, intersecting each other at 90-degree angles, for hinged mounting of the support rod II or the hydraulic cylinder. The support rod II 330 is hingedly mounted on the lower sleeve II, with its lower end hinged to the sleeve II. The chuck 340 is mounted on the other end (upper end) of the support rod II via a hinged pin, i.e., the chuck is mounted on the top of the support rod II. The main body of the chuck 340 is a machined metal block, and an anti-slip material layer 341, such as a wear-resistant rubber layer, is bonded to its outer surface with a strong adhesive. To increase the bonding strength between the wear-resistant rubber layer and the metal block, a convex-concave interlocking structure is provided between them, that is, the bonding surface between the wear-resistant rubber layer and the metal block has a convex-concave interlocking structure. The support rod II 330 is inclined, and a hinge hole is provided in the middle section of the support rod II 330 for the movable connection of the hydraulic cylinder, that is, hinged installation. The upper end of the aforementioned hydraulic cylinder 320 is hinged to the upper sleeve II, and the other end of the hydraulic cylinder 320, that is, the lower end, is hinged to the hinge hole in the middle section of the support rod II.

[0037] The aforementioned support rods II330 and hydraulic cylinders 320 are four in number and arranged at a 90-degree angle to each other to form four support structures. These support structures are elastic supports. By controlling the extension and retraction of the four hydraulic cylinders, the aforementioned claws are made to adhere to the inner wall of the prefabricated pipe 01 to be hoisted.

[0038] In the hoisting state, the aforementioned support and lifting mechanism is positioned above the guide mechanism, meaning that the guide mechanism is positioned below the support and lifting structure. This is because the guide mechanism is used to guide the insertion action of the pipe below.

[0039] The usage method is as follows:

[0040] First, insert the device horizontally from one side to the other inside the prefabricated pipe 01 to be installed, referring to... Figure 3 The clamps of the lifting mechanism are positioned in the middle of the precast pipe. Hydraulic oil is then supplied to the hydraulic cylinder, which, under its support, firmly presses the clamps against the inner wall of the precast pipe. The pipe is then lifted using the hoisting equipment, gradually approaching the inlet and slowly lowering it. (Refer to...) Figure 4Under the hoisting equipment, the precast pipe is gradually moved closer to the precast pipe 02 already installed below. During its descent, the guide mechanism is gradually inserted into the lower precast pipe. This guide mechanism guides the hoisted precast pipe to align with the lower precast pipe, achieving automatic alignment and concentricity between the two pipes during the descent. After installation, concrete is filled around the outside of the precast pipe for initial positioning. Then, the hydraulic cylinder is depressurized, and the device is lifted out of the precast pipe, completing the installation of one section of the precast pipe.

[0041] This process is repeated until all prefabricated pipes are installed.

[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
