Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated construction, in particular to an on-site electromechanical pipeline pre-buried structure for prefabricated construction. Background Art

[0002] Currently, installing electromechanical pipelines through floors or walls is a necessity in the construction industry. There are two existing installation methods. One involves punching or drilling holes through the floor or wall, which not only increases construction time but also easily causes cracks in the floor or wall. The other method involves pre-embedded casings in the floor or wall. Existing pre-embedded pipeline devices, especially those that penetrate inner walls (beams), are left directly inside the wall after pouring, making them impossible to reuse later and resulting in high production costs.

[0003] For example, Chinese patent publication CN216530403U discloses a pre-buried structure for electromechanical installation pipelines. During use, a fixed tube is inserted into an opening in a floor or wall and fixedly connected to the floor or wall. A threading tube is used to thread electromechanical pipelines. The threading tube and the fixed tube are slidably connected. During installation, the threading tube is placed into the fixed tube using a handle at the end of the threading tube. The fixed tube supports, secures, and protects the threading tube. During removal, the threading tube is removed from the fixed tube using a handle at the end of the threading tube. After removal, the threading tube remains intact and can be reused, reducing post-production costs.

[0004] However, the pre-buried structure for electromechanical installation pipelines in the above application requires pre-setting the slide rails inside the fixed cylinder, which increases the production cost, and can only be used for routing specific fixed cylinders, with a limited scope of application. Therefore, there are certain limitations.

[0005] To this end, we urgently need to provide a pre-buried structure for on-site electromechanical pipelines for prefabricated construction. Utility Model Content

[0006] The purpose of the present utility model is to provide a pre-buried structure for electromechanical pipelines on site for assembled construction, so as to solve the problem that the pre-buried structure for electromechanical installation pipelines proposed in the above-mentioned background technology requires pre-setting slide rails inside the fixed cylinder in advance, which increases production costs, and can only route wires for specific fixed cylinders, and has a limited scope of application.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pre-buried structure for electromechanical pipelines on site for assembled construction, comprising a wall and a fixing tube, wherein the fixing tube is buried inside the wall, and an burying device is installed inside the fixing tube.

[0008] The embedding device includes a wire-releasing unit and a clamping unit.

[0009] The pay-off unit includes a pay-off block, an adjusting cylinder, a threaded rod, and a pay-off assembly. The pay-off block is placed inside the fixed cylinder, the two adjusting cylinders are fixedly connected to the front and rear sides of the pay-off block, the two threaded rods are respectively installed inside the adjusting cylinder, and the two pay-off assemblies are respectively installed on the outer ends of the threaded rods.

[0010] A further improvement is that the inner wall of the adjusting cylinder is provided with an internal thread matching the threaded rod, and the two are threadedly connected. When facing fixed cylinders with different inner diameters, the threaded rod is twisted to rotate it outward from the inside of the adjusting cylinder until the wire-releasing assembly on its outside abuts against the inner wall of the fixed cylinder to adapt to fixed cylinders with different inner diameters, thereby improving the applicability of the device.

[0011] A further improvement is that the line-paying assembly includes a wheel frame, a rotating bearing, a rotating shaft, and a roller. The wheel frame is fixedly connected to the outer end of the threaded rod, and the two rotating bearings are respectively installed on the left and right inner walls of the wheel frame. The rotating shaft is rotatably connected to the inside of the rotating bearing, and the roller is fixedly connected to the outer surface of the rotating shaft. When the roller in the line-paying assembly abuts the inner wall of the fixed cylinder, the line-paying block is released, and the roller slides downward along the inner wall of the fixed cylinder under the action of gravity, thereby driving the rotating shaft inside it to rotate inside the rotating bearing inside the wheel frame, thereby completing the line-paying.

[0012] A further improvement is that wire-laying holes are respectively opened at the four corners of the upper surface of the wire-laying block, and clamping units are respectively provided on the left and right sides of the four wire-laying holes. Multiple groups of wires are respectively passed through and placed inside the wire-laying holes, so that multiple groups of lines can be pre-buried at one time, which improves the efficiency of pre-buried wire laying and avoids the occurrence of different types of pipelines being entangled with each other.

[0013] A further improvement is that the clamping unit includes a storage chamber, a magnet, an elastic rope, a sliding rod, and a clamping plate. The storage chamber is opened on the left inner wall of the wire-releasing hole, the magnet is installed on the inner wall of the storage chamber, the elastic rope is fixedly connected to the center of the outer surface of the magnet, the sliding rod is fixedly connected to the right end of the elastic rope, and the clamping plate is fixedly connected to the right end of the sliding rod.

[0014] A further improvement is that a non-slip rubber pad is adhered to the outer surface of the clamping plate, and the sliding rod is made of magnetic material. Before paying out the line, the pipeline is passed through the inside of the clamping plate, and then a repulsive force is generated between the magnet and the sliding rod, thereby pushing the sliding rod to slide outward along the inner wall of the storage cavity, thereby clamping and fixing pipelines of different diameters to prevent them from falling off during the paying out process. The provision of the non-slip rubber pad increases the friction between the clamping plate and the pipeline, making the clamping more firm and stable.

[0015] A further improvement is that the fixed tube has a rectangular structure, and the bottom of the fixed tube is connected to a square rubber hose. The upper and lower ends of the square rubber hose are respectively fixedly connected with rubber clamps, and the rubber clamps are clamped to the outside of the fixed tube. When splicing two walls, the rubber clamp at one end of the square rubber hose is screwed into the fixed tube inside the No. 1 wall, and then the rubber clamp at the other end is screwed into the fixed tube inside the No. 2 spliced ​​wall, until the pipeline is lowered into the interior of the square rubber hose through the line-laying unit, and then transferred into the fixed tube inside the No. 2 spliced ​​wall, thereby quickly completing the burial of the pipeline.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When facing fixed cylinders with different inner diameters, the pre-buried structure for electromechanical pipelines for prefabricated construction can adapt to fixed cylinders with different inner diameters by twisting the threaded rod to rotate it outward from the inside of the adjustment cylinder until the wire-laying assembly on the outside abuts against the inner wall of the fixed cylinder, thereby increasing the applicability of the device.

[0018] 2. This pre-buried structure for on-site electromechanical pipelines for prefabricated construction requires the pipelines to pass through the inside of the clamping plate before laying out the lines. A repulsive force is then generated between the magnet and the slide bar, pushing the slide bar to slide outward along the inner wall of the storage cavity, thereby clamping and fixing pipelines of different diameters to prevent them from falling off during the laying-out process.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Example 1:

[0028] A pre-buried structure for electromechanical pipelines on site for assembled construction comprises a wall 1 and a fixing tube 2. The fixing tube 2 is buried inside the wall 1, and an burying device is installed inside the fixing tube 2.

[0029] The embedding device includes a wire-laying unit.

[0030] The pay-off unit includes a pay-off block 301, an adjusting cylinder 302, a threaded rod 303, and a pay-off assembly 304. The pay-off block 301 is placed inside the fixed cylinder 2, and the two adjusting cylinders 302 are fixedly connected to the front and back sides of the pay-off block 301 respectively. The two threaded rods 303 are respectively installed inside the adjusting cylinder 302, and the two pay-off assemblies 304 are respectively installed at the outer ends of the threaded rods 303.

[0031] The inner wall of the adjusting cylinder 302 is provided with an internal thread that matches the threaded rod 303, and the two are threadedly connected. When facing fixed cylinders 2 with different inner diameters, the threaded rod 303 is screwed to rotate it outward from the inside of the adjusting cylinder 302 until the wire-releasing assembly 304 on its outside abuts against the inner wall of the fixed cylinder 2 to adapt to fixed cylinders 2 with different inner diameters, thereby improving the applicability of the device.

[0032] The line-releasing assembly 304 includes a wheel frame 3041, a rotating bearing 3042, a rotating shaft 3043, and a roller 3044. The wheel frame 3041 is fixedly connected to the outer end of the threaded rod 303, and the two rotating bearings 3042 are respectively installed on the left and right inner walls of the wheel frame 3041. The rotating shaft 3043 is rotatably connected to the inside of the rotating bearing 3042, and the roller 3044 is fixedly connected to the outer surface of the rotating shaft 3043. When the roller 3044 in the line-releasing assembly 304 abuts against the inner wall of the fixed cylinder 2, the line-releasing block 301 is released, and the roller 3044 slides downward along the inner wall of the fixed cylinder 2 under the action of gravity, thereby driving the rotating shaft 3043 inside it to rotate inside the rotating bearing 3042 inside the wheel frame 3041, thereby completing the line-releasing.

[0033] The fixing tube 2 is a rectangular structure, and a square rubber hose 401 is connected to the bottom of the fixing tube 2. The upper and lower ends of the square rubber hose 401 are respectively fixedly connected with rubber clamps 402, and the rubber clamps 402 are clamped on the outside of the fixing tube 2. When splicing two walls 1, the rubber clamp 402 at one end of the square rubber hose 401 is screwed into the fixing tube 2 inside the No. 1 wall 1, and then the rubber clamp 402 at the other end is screwed into the fixing tube 2 inside the No. 2 spliced ​​wall 1, until the pipeline is lowered into the interior of the square rubber hose 401 through the pay-off unit, and then transferred into the fixing tube 2 inside the No. 2 spliced ​​wall 1, thereby quickly completing the burial of the pipeline.

[0034] Example 2:

[0035] On the basis of Example 1, wire-laying holes 305 are respectively opened at the four corners of the upper surface of the wire-laying block 301, and clamping units are respectively provided on the left and right sides of the four wire-laying holes 305. Multiple groups of wires are respectively passed through and placed inside the wire-laying holes 305, so that multiple groups of lines can be pre-buried at one time, which improves the efficiency of pre-buried wire laying and avoids the occurrence of different types of pipelines being entangled with each other.

[0036] The burying device includes a clamping unit, which includes a storage chamber 306, a magnet 307, an elastic rope 308, a slide rod 309, and a clamping plate 310. The storage chamber 306 is opened on the left inner wall of the wire-releasing hole 305, the magnet 307 is installed on the inner wall of the storage chamber 306, the elastic rope 308 is fixedly connected to the center of the outer surface of the magnet 307, the slide rod 309 is fixedly connected to the right end of the elastic rope 308, and the clamping plate 310 is fixedly connected to the right end of the slide rod 309.

[0037] The outer surface of the clamping plate 310 is adhered with a non-slip rubber pad, and the slide rod 309 is made of magnetic material. Before paying out the line, the pipeline is passed through the inside of the clamping plate 310, and then a repulsive force is generated between the magnet 307 and the slide rod 309, thereby pushing the slide rod 309 to slide outward along the inner wall of the storage cavity 306, thereby clamping and fixing pipelines of different diameters to prevent them from falling off during the paying out process. The setting of the non-slip rubber pad increases the friction between the clamping plate 310 and the pipeline, making the clamping more firm and stable.
