Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a line-laying device for building construction projects. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, including foundation construction, main structure construction, roof construction, and decoration construction. A large number of cables are used in the building construction process, and when workers are carrying out wiring construction, they usually need to use cable laying devices to release the cable rolls.

[0003] For example, CN221916716U discloses a cable laying device for building construction projects. The technical problem of this utility model is: to provide a cable laying device for building construction projects that can control the rapid rotation of the cable reel to prevent cable tangling. Technical solution: A cable laying device for building construction projects includes a vehicle body; the vehicle body has a sliding groove, within which a concave chuck is symmetrically slidably connected; it also includes a rotating disk, on which a rotating shaft is fixedly connected, rotatably connected to the concave chuck; centrifugal blocks are evenly distributed on the circumferential surface of the rotating disk. When the speed of the cable laying movement increases, the cable reel will generate inertia, and with this inertia, the reel will rotate rapidly, and the cable wound inside the reel will be quickly released. The centrifugal blocks, in conjunction with a brake lever, effectively prevent the cable inside the reel from accumulating and tangling.

[0004] However, in the existing technology, environmental factors such as strong winds and vibrations can easily cause the wire laying device to sway, affecting the measurement stability. The device has weak anti-interference ability, is difficult to place stably on sloping ground, and has poor terrain adaptability, which limits the practicality of the device to a certain extent.

[0005] The purpose of this invention is to solve the problems in the prior art where the wire laying device is easily shaken due to environmental factors such as strong winds and vibrations, affecting measurement stability, and the device has weak anti-interference ability, is difficult to place stably on sloping ground, and has poor terrain adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a line-laying device for building construction engineering, comprising a main body, wherein a first mounting groove and a second mounting groove are sequentially formed on the upper surface of the main body from left to right, a positioning mechanism is provided inside the second mounting groove, and an adsorption mechanism is provided on the lower surface of the main body, the adsorption mechanism comprising fixed plates symmetrically fixed on both sides of the lower surface of the main body, a third lead screw is driven inside the fixed plate, a rotating shaft is driven at one end of the third lead screw, and the two sets of rotating shafts are connected by synchronous belt drive, a second motor is fixedly installed at one end of the lower surface of the main body near the rotating shaft, and the output end of the second motor is drivenly connected to the outer end of one set of rotating shafts, an upper mounting plate is symmetrically driven on the surface of the third lead screw, telescopic rods are symmetrically fixed on both sides of the middle of the lower surface of the main body, and a counterweight plate is fixedly installed at the bottom end of the telescopic rod, a plurality of shock-absorbing springs are elastically arranged in the gap between the counterweight plate and the main body, a lower mounting plate is symmetrically fixed on both sides of the upper surface of the counterweight plate, and the lower mounting plate abuts against the upper mounting plate, and a vacuum suction cup is provided on the lower surface of the counterweight plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention, by setting up an adsorption mechanism, works on a slope. By starting a second motor, the output of the second motor drives a rotating shaft and a synchronous belt to rotate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a line-laying device for building construction engineering, including a main body 1. The upper surface of the main body 1 has a first mounting groove 2 and a second mounting groove 3 sequentially formed from left to right. A positioning mechanism is provided inside the second mounting groove 3. An adsorption mechanism is provided on the lower surface of the main body 1. The adsorption mechanism includes fixed plates 22 symmetrically fixed on both sides of the lower surface of the main body 1. A third lead screw 23 is driven inside the fixed plate 22. A rotating shaft 25 is driven at one end of the third lead screw 23. The two sets of rotating shafts 25 are connected by a synchronous belt 26. A second motor 27 is fixedly installed on one end of the lower surface of the main body 1 near the rotating shaft 25, and the output end of the second motor 27 is drivenly connected to the outer end of one set of rotating shafts 25. An upper mounting plate 24 is symmetrically driven on the surface of the third lead screw 23. Telescopic rods 18 are symmetrically fixed on both sides of the middle of the lower surface of the main body 1, and a [missing information - likely a device or component] is fixedly installed at the bottom end of the telescopic rods 18. The counterweight plate 20 has several shock-absorbing springs 19 elastically arranged in the gap between it and the main body 1. The lower mounting plate 21 is symmetrically fixed on both sides of the upper surface of the counterweight plate 20, and the lower mounting plate 21 abuts against the upper mounting plate 24. The lower surface of the counterweight plate 20 is provided with a vacuum suction cup. The contact surfaces of the lower mounting plate 21 and the upper mounting plate 24 are both inclined surfaces. When on a slope, the second motor 27 is started. The output end of the second motor 27 drives the rotating shaft 25 and the synchronous belt 26 to rotate. The rotating shaft 25 drives the third lead screw 23 to rotate. The third lead screw 23 drives the upper mounting plate 24 to move towards each other. The upper mounting plate 24 drives the counterweight plate 20 to move downward through the lower mounting plate 21, and simultaneously stretches the telescopic rod 18 and the shock-absorbing springs 19, so that the counterweight plate 20 lifts the device and the vacuum suction cup adheres to the slope. With the cooperation of vacuum adsorption and counterweight plate 20, the practicality and anti-interference ability of the device are improved.

[0024] like Figure 1-4As shown, universal wheels 17 are rotatably mounted at the four corners of the lower surface of the main body 1. A first lead screw 4 is driven inside the first mounting groove 2. A movable frame 5 is symmetrically mounted on the surface of the first lead screw 4. A first motor 10 is fixedly mounted on the outer surface of one movable frame 5, and the output end of the first motor 10 is connected to the outer end of the movable rod 6 on one side. Movable rods 6 are symmetrically mounted on the inner sides of the two sets of movable frames 5. A sleeve block 7 is fitted on the surface of the movable rod 6. A receiving plate 8 is fixedly mounted on the outer surface of the sleeve block 7. The sleeve block 7 and the movable rod 6 are connected by a locking bolt 9. Different models of receiving plates 8 can be replaced according to the size of the cable reel. By fitting the sleeve block 7 onto the surface of the movable rod 6 and installing it by the locking bolt 9, rotating the first lead screw 4 causes the movable frames 5 to move towards each other, so that the two sets of receiving plates 8 move closer to each other to install the cable body. The installation and disassembly are convenient and easy to use.

[0025] like Figure 1-4 As shown, the positioning mechanism includes a second lead screw 11, which is driven in the inner cavity of the second mounting groove 3. A mounting frame 12 is driven on the surface of the second mounting groove 3. A lower transmission roller 13 is provided on the inner bottom wall of the mounting frame 12. A screw 14 is threaded at the center of the upper surface of the mounting frame 12. An upper transmission roller 15 is driven at the bottom end of the screw 14. Several return springs 16 are elastically arranged between the upper surface of the upper transmission roller 15 and the inner top wall of the mounting frame 12. By turning the upper transmission roller 15, the screw 14 drives the upper transmission roller 15 to move down while stretching the return springs 16. The lower transmission roller 13 and the upper transmission roller 15 position the cable, ensuring the accuracy of cable laying.

[0026] Working Principle: During use, different models of receiving plates 8 are replaced according to the size of the cable reel. The sleeve 7 is fitted onto the surface of the movable rod 6 and installed using the threaded locking bolt 9. Rotating the first lead screw 4 causes the moving frame 5 to move towards each other, bringing the two sets of receiving plates 8 closer together to install the cable body. Next, one end of the cable is placed through the mounting frame 12 onto the surface of the lower transmission roller 13. Tightening the upper transmission roller 15 causes the screw 14 to move the upper transmission roller 15 downwards, simultaneously stretching the return spring 16. The lower and upper transmission rollers 13 and 15 position the cable, ensuring accurate cable laying. The first motor 10 is started, driving the cable body to rotate and achieving cable laying under external tension. The second lead screw 11 is then rotated. The second lead screw 11 drives the mounting frame 12 to move horizontally, thereby controlling the angle of the line laying. The universal wheel 17 drives the device to move. When the device moves to a horizontal or sloping surface, the second motor 27 is started. The output end of the second motor 27 drives the rotating shaft 25 and the synchronous belt 26 to rotate. The rotating shaft 25 drives the third lead screw 23 to rotate. The third lead screw 23 drives the upper mounting plate 24 to move towards each other. The upper mounting plate 24 drives the counterweight plate 20 to move downward through the lower mounting plate 21, and simultaneously stretches the telescopic rod 18 and the shock-absorbing spring 19, so that the counterweight plate 20 lifts the device, allowing the vacuum suction cup to adhere to the slope. With the cooperation of vacuum adsorption and counterweight plate 20, the practicality and anti-interference ability of the device are improved, ensuring the safe and stable operation of the equipment, and making it suitable for large-scale promotion.
