Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a line-laying device for construction engineering and a use method thereof. Background Art

[0002] In order to ensure accurate dimensions during construction, a reference system is often established by laying out wires. Under existing conditions, holes, connecting blocks and rotating seats are often set up to facilitate the installation and use of winding rollers. However, the ropes made of nylon cannot withstand long-term wear and tear, so they need to be replaced frequently, especially when the ropes are used up, the bolts in the hole at one end of the shaft need to be removed, which is a cumbersome fixing structure.

[0003] For example, a wire-laying auxiliary positioning device for construction engineering disclosed in announcement number CN221173391U is provided with a positioning component, which inserts the wire head into the wire-laying hole, and assists in positioning the wire-laying through the cooperation of the wire-laying hole and the roller, thereby improving the accuracy of wire-laying and effectively improving the efficiency of wire-laying. However, a fixing frame is fixedly connected to the inside of the support column, and a wire-laying stick is installed on one side of the fixing frame. The setting of the winding roller adopts a simple structure and an unclear fixing method, which not only makes it difficult to ensure the placement and installation stability of the winding roller, but also makes it difficult to perform the replacement operation. In particular, it is difficult to control the rotation of the winding roller while fixing the winding roller, which can easily cause the rope to loosen and fall off, and the tightness of the rope cannot be guaranteed during the wire-laying process. The loose rope not only cannot play the role of a straight line reference, but is more likely to cause confusion and chaos.

[0004] For example, a wire-releasing device for construction projects disclosed in announcement number CN118164332B controls the slider and linear moving parts through a control module during the process of reeling and releasing the wire rope to prevent the wire rope from being broken due to excessive tension (pulling force). Although the tightness of the wire rope can be ensured during the wire-releasing process, the repeatedly reeled and released wire rope is repeatedly in friction contact with other wire-releasing structures. If there is a large friction resistance between the two, the wear and consumption of the wire rope will be easily aggravated, which will not only affect the smoothness of the wire-releasing process, but also seriously shorten the service life of the wire rope, and increase the supporting cost burden during the construction process.

[0071] 2. The present invention arranges a positioning fixture corresponding to the load-bearing round rod on the telescopic square rod. The upper tensioning rod and the lower tensioning rod symmetrically distributed in the center line in the positioning fixture can lock and fix the load-bearing round rod rotated to any angle through the positioning arc plate when they are closed toward each other, so that the load-bearing round rod supporting the winding roller can be effectively prevented from rotating.

[0072] 3. The present invention arranges an extension bracket at the front end of the machine body, and arranges a lever traction plate which is acted upon by a strong spring and the gravity of a clamping plate between the supporting bracket and the extension bracket. The lever traction plate is utilized to ensure that the first guide block and the second guide block always maintain a tendency to move in opposite directions, thereby staggering and propping up the first steering roller and the second steering roller, so that the rope released from the winding roller always remains in a taut state when passing through the first steering roller, the second steering roller and the clamping plate.

[0073] 4. The present invention provides a square cavity, an extension cavity and a columnar bayonet for filling and circulating lubricating oil in the extension bracket, and provides a piston sealing plate elastically supported by a booster spring in the opening and closing plate, so that a lubrication roller that can be extended and rotated to contact the lubricating oil can be provided in the columnar bayonet. The drooping rope exerts pressure on the lubrication roller while also contacting the lubricating oil, thereby lubricating the rope and avoiding severe wear and consumption between the rope and the wire-releasing structure.

[0149] The number of the booster discs 203 is two. The two booster discs 203 are respectively fixedly sleeved on the two ends of the horizontal shaft 201.

[0150] The locking sockets 204 are in two groups, and the two groups of locking sockets 204 are respectively opened at both ends of the horizontal axis 201. By inserting a driven piston plug 40605 in the locking sockets 204, the winding roller 2 can be locked and fixed in the load-bearing round rod 405.

[0151] Please refer to the instruction manual for details Fig.12 A traction bolt 506 is integrally connected to the first guide block 503, and a traction long hole 507 for slidingly fitting the traction bolt 506 is opened in one end of the lever traction plate 505, and a synchronous connecting rod 508 is pin-connected between the other end of the lever traction plate 505 and the second guide block 504.

[0152] Please refer to the instruction manual for details Fig.13 A micro-hole is provided in the opening and closing plate 514 to unidirectionally connect the extension cavity 602 and the columnar bayonet 603 , and the lubricating oil in the extension cavity 602 flows into the columnar bayonet 603 through the micro-hole in a unidirectional manner.

[0153] It should be noted that the specific models and specifications of the drive motor 3 and the automatic telescopic device 40703 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0154] The present invention can be explained by the following operation mode:

[0155] First, the two ends of the transverse axis 201 of the winding roller 2 are respectively inserted into the two central cavities 40503, so that the free end of the rope passes through the first steering roller 509, the second steering roller 510 and the lubrication roller 608 in sequence, so that the rope is paid out in a multiple wavy structure, thereby tensioning and supporting the rope.

[0156] Secondly, control the drive motor 3 to turn on, so that the double-headed rocker arm 402 pulls the two movable supports 401 to move toward each other through the traction link 403, and the horizontal axis 201 extends into the central cavity 40503. The pressure-bearing ring 40603 is pressurized by the booster disc 203. The pressure-bearing ring 40603 drives the drive piston 40604 to extend into the right-angle long cavity 40602, so that the driven piston plug 40605 extends out of the right-angle long cavity 40602 until the driven piston plug 40605 is snap-connected with the locking socket 204, so as to facilitate the replacement and fixation of the winding roller 2 in the load-bearing round rod 405.

[0157] Next, the winding roller 2 is pulled by the rope, and the first guide block 503 is pressed under the tension of the strong spring 512, so that the first steering roller 509 moves vertically downward, and the first guide block 503 pulls the lever traction plate 505 to deflect, so that the second steering roller 510 moves vertically upward to tension and support the rope, and the lifting rod 511 pulls the opening and closing plate 514 through the traction cable 515, so that the opening and closing plate 514 repeatedly opens and closes with the base 10302 as the fulcrum, ensuring that the wavy rope is always in a taut state, avoiding the loose rope from folding and overlapping to cause winding and confusion;

[0158] Then, during the release process of the rope passing through the lubrication roller 608, the piston booster plate 605 is driven by the telescopic rod 606 to shrink into the square cavity 601, and the lubricating oil in the square cavity 601 is squeezed into the oil drain pipe 607. The lubricating oil enters the extension cavity 602 through the oil drain pipe 607, and the lubricating oil that enters the columnar bayonet 603 through the micropores repeatedly contacts the lubrication roller 608 to coat the rope passing through the lubrication roller 608. The lubrication roller 608 that repeatedly retracts and rotates unidirectionally applies the lubricating oil to the rope, thereby ensuring that the friction resistance between the rope and the machine body 1 is reduced.

[0159] Finally, when the rope is retracted and released to the required extent, the automatic retractor 40703 is controlled to open to drive the lever rocker 40704 to deflect, and the upper tensioning and closing rod 40701 and the lower tensioning and closing rod 40702 are driven to deflect towards each other through the upper pull rod 40705 and the lower pull rod 40706, and the load-bearing round rod 405 is fixed by the positioning arc plate 40707. The load-bearing round rod 405 is fixed by controlling the rotation of the winding roller 2 to avoid excessive release of the rope.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
