Description

Technical Field

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

[0002] Setting out lines is a core step in ensuring construction accuracy. It involves precisely transferring the dimensions, locations, and elevations from the design drawings to the construction site, providing a benchmark for subsequent construction. Setting out lines involves the use of setting-out devices, which are common tools and widely used by operators.

[0003] Most existing engineering construction layout devices are traditional ink markers. Using ink markers requires two people, results in inaccurate layout, and is inefficient, failing to meet the needs of engineering construction. Furthermore, existing layout devices cannot adjust the layout height, causing significant inconvenience for workers. This falls far short of current requirements for such products. Chinese patent document CN 222063663 U describes a construction engineering layout device, but its complex structure and inconvenient use necessitate improvement. Utility Model Content

Detailed Implementation

[0025] like Figure 1-7 In this invention, a rapid wire laying device for engineering construction includes a base 1 and an auxiliary frame 2. A rotating rod 3 is rotatably inserted through the middle of the base 1 and the auxiliary frame 2. A winding wire 4 is sleeved on the rotating rod 3. A drive rod 5 is provided on the top of the rotating rod 3. A limiting component 6 is detachably provided on the base 1. The limiting component 6 includes an adjusting rod 602 and an end cap 603. The adjusting rod 602 and the end cap 603 are connected to form a constraint space 608. The winding wire 4 is inserted into the constraint space 608.

[0026] In use, the operator holds the drive rod 5 and applies torque to the rotating rod 3, thereby tightening or loosening the winding 4. At the same time, because the winding 4 is limited by the constrained space 608, it is ensured that it can be measured at a relatively fixed height during the movement of the winding 4, thereby improving the accuracy of the measurement and preventing deviation during measurement. The base 1 and auxiliary frame 2 have a compact structure and are simple to manufacture. The base 1 and auxiliary frame 2 ensure the flexible and convenient rotation of the rotating rod 3, and ensure that the rotation process does not deviate from the top and bottom sides of the rotating rod 3.

[0027] In a preferred embodiment, the base 1 includes a disc 101, a ring platform 108 is provided in the middle of the disc 101, a countersunk hole 109 is provided in the ring platform 108, and a bearing 10 is sleeved on the lower side of the rotating rod 3, the bearing 10 being located in the countersunk hole 109.

[0028] The bottom of the rotating rod 3 and the bearing 10 are fixed by an interference fit. The bearing 10 ensures that the rotating rod 3 rotates smoothly, is easy to install and disassemble, and has a good performance.

[0029] In the preferred embodiment, the height of the countersunk hole 109 is greater than the height of the bearing 10, the fixing sleeve 11 is detachably sleeved on the rotating rod 3, the fixing sleeve 11 and the countersunk hole 109 are threadedly connected, and the bottom of the fixing sleeve 11 is pressed against the top of the bearing 10.

[0030] The fixing sleeve 11 can further fix the bearing 10, ensuring its stable operation. At the same time, the fixing sleeve 11 is easy to install and further improves the rotation accuracy of the rotating rod 3.

[0031] In the preferred embodiment, the upper side of the countersunk hole 109 is provided with an internal thread 110, the fixing sleeve 11 includes a ring 1101 and a cover plate 1102, the middle part of the cover plate 1102 is provided with a sixth through hole 1103, the rotating rod 3 passes through the sixth through hole 1103, the outer side of the ring 1101 is provided with an external thread 1104, and the external thread 1104 and the internal thread 110 are in the same direction.

[0032] The outer diameter of the cover plate 1102 is larger than the outer diameter of the ring 1101, which ensures convenient installation. The operator can rotate the cover plate 1102 to adjust the pressure on the top of the bearing 10, while ensuring a relatively clean working environment for the bearing 10 and preventing external dirt from entering and damaging the bearing 10.

[0033] In a preferred embodiment, the disc 101 has a second through hole 107 in the middle, the rotating rod 3 passes through the second through hole 107, and a plurality of first ear plates 102 are evenly distributed on the outer side of the disc 101. The first ear plates 102 are provided with first through holes 104, and the insert rod 7 passes through the first through holes 104.

[0034] The base 1 is fixed in the position to be measured by inserting the rod 7, which ensures stability during measurement and avoids the problem of inconvenience in winding and unwinding the cable.

[0035] In a preferred embodiment, a plurality of second ear plates 103 are evenly distributed on the outer side of the disc 101. A first threaded hole 105 is provided through the second ear plate 103. The auxiliary frame 2 includes a plurality of L-shaped plates 201 arranged circumferentially. A third through hole 203 is provided through the L-shaped plate 201. Screws 8 are inserted into the third through hole 203 and the first threaded hole 105. The plurality of L-shaped plates 201 are connected by a top plate 202.

[0036] Multiple L-shaped plates 201 work together to provide relatively sufficient winding space. The cooperation between the L-shaped plates 201 and the base 1 ensures the precise position of the top plate 202, thereby limiting the top of the rotating rod 3 and ensuring its rotation accuracy. The auxiliary frame 2 and the base 1 are easy to install and remove and simple to fix.

[0037] In the preferred embodiment, the top plate 202 has a fourth through hole 206 in the middle, the rotating rod 3 passes through the fourth through hole 206, the top of the fourth through hole 206 has a sleeve 204, and the outer side of the sleeve 204 has a plurality of third threaded holes 205 evenly distributed. The rotating rod 3 includes a rod body 301, the upper side and the lower side of the rod body 301 are respectively provided with a lock head 303 and a limiting plate 302, the lock head 303 is provided with a plurality of locking grooves 304, the locking pin 9 passes through the third threaded hole 205, and the end of the locking pin 9 abuts against the locking groove 304.

[0038] When the winding 4 is being measured, it needs to be temporarily fixed in order to ensure the accuracy of the measurement. The locking pin 9 limits the top of the rotating rod 3 and, together with the locking groove 304, prevents the rotating rod 3 from rotating, thus ensuring efficient and accurate use. The bottom limiting plate 302 supports the winding 4 and prevents the winding 4 from being in a low position and interfering with other components when winding and unwinding.

[0039] In a preferred embodiment, the locking pin 9 includes a screw 901 and a frustum 902. The frustum 902 has symmetrically arranged contact plates 903 on its outer side. The end of the screw 901 has a pointed tip 904. The screw 901 passes through the third threaded hole 205.

[0040] When in use, the staff holds the contact plate 903 to more easily rotate the screw 901, thereby changing the position of the tip 904. Multiple locking pins 9 work together to serve as backups for each other.

[0041] In a preferred embodiment, the first ear plate 102 is provided with a plurality of second threaded holes 106 evenly distributed thereon. The bottom of the adjusting rod 602 is threadedly connected to a support sleeve 601, which is detachably disposed in the second threaded holes 106. The top of the adjusting rod 602 is provided with a fixing head 604, and the fixing head 604 is provided with a through groove 605 in the middle. The end cap 603 is threadedly connected to the fixing head 604. The through groove 605 and the end cap 603 are respectively provided with a first fillet 606 and a second fillet 607.

[0042] In use, multiple support sleeves 601 can be installed, and thread-locking adhesive can be applied to the support sleeves 601 to ensure that the support sleeves 601 remain fixed in the second threaded hole 106 and do not come off when the adjusting rod 602 is rotated due to the adhesive effect of the thread-locking adhesive. After the adjusting rod 602 is adjusted to a suitable height, the through groove 605 is aligned with the rotating rod 3, and then the adjusting rod 602 is temporarily fixed. The winding 4 is inserted into the through groove 605, and finally the end cap 603 is installed on the fixing head 604. While rotating the end cap 603 with one hand, the other hand keeps the adjusting rod 602 in a relatively fixed state until the end cap 603 is installed in the designed position. Then the constraint on the adjusting rod 602 is released. Through the above settings, the height position of the constraint space 608 can be flexibly changed to meet the needs of the wire feeding operation and improve the overall convenience of use.

[0043] In a preferred embodiment, the top of the rotating rod 3 is provided with a fourth threaded hole 305, the driving rod 5 includes a connecting plate 501 and a gripping post 502, the connecting plate 501 is provided with a fifth through hole 503, and the winding wire 4 passes through the fifth through hole 503 and the fourth threaded hole 305.

[0044] The connecting plate 501 extends the lever arm, making operation more convenient and labor-saving, and simplifying overall maintenance.
