Description

Technical Field

[0001] This utility model belongs to the field of wire laying measurement technology, and specifically relates to a wire laying measurement device. Background Technology

[0002] Setting out is a construction method that uses measuring tools to project key dimensions such as building axes, wall boundaries, and door and window positions from the design drawings onto the construction site. This ensures that the project is carried out strictly according to the plan. Setting out is a fundamental step in construction and directly affects the quality of the project, structural safety, and functional realization. If the setting out error is too large, it may lead to problems such as wall tilting and equipment installation failure.

[0003] Most existing line-laying and measuring equipment uses the extension of the measuring rope for manual line-laying and measuring. However, when the extension of the measuring rope is too large, the middle position of the measuring rope is affected by its own weight and the bending range is large. It is inconvenient for people to straighten the measuring rope completely, resulting in large errors in the measurement data, which affects the construction quality. Utility Model Content

[0004] The purpose of this invention is to provide a line-laying and measuring device that solves the problem that existing line-laying and measuring devices mostly rely on the extension of measuring ropes for manual line laying and measuring. However, when the length of the measuring rope is too long, the middle position of the measuring rope is affected by its own weight and the bending amplitude is large. It is inconvenient for manual operation to completely straighten the measuring rope, resulting in large measurement data errors and thus affecting the construction quality.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A wire laying and measuring device, comprising:

[0007] A trolley, with a measuring rope installed on top of it;

[0008] A rope winding mechanism is provided on the top surface of the trolley. The rope winding mechanism is used to wind and extend the measuring rope and fix the position of the end of the measuring rope near the rope winding mechanism relative to the trolley.

[0009] A support mechanism is provided above the trolley and is used to support the measuring rope.

[0010] In a preferred embodiment, self-locking casters are fixedly installed at the four corners of the bottom surface of the trolley, and a handle is fixedly installed on the top surface of the trolley.

[0011] In a preferred embodiment, the rope winding mechanism includes a fixed plate, a rotating rod, a baffle plate, a rope winding roller, a rotating plate, a connecting rod, a baffle plate, a crank handle, a first knob, a first threaded rod, and a pressure plate. Symmetrical fixed plates are fixedly mounted on the top surface of the trolley. A rotating rod extending from the front to the back of each fixed plate is rotatably connected to the fixed plate. A baffle plate is fixedly mounted on each side of the rotating rods that are close to each other. The baffle plate is rotatably connected to the fixed plate. A rope winding roller is fixedly mounted on the side of the baffle plate that is close to each other. One end of the measuring rope is fixedly connected to the outer side of the rope winding roller. A rotating plate is fixedly mounted on the front of one of the rotating rods. A connecting rod is fixedly mounted on the front of the rotating plate, and a baffle is fixedly mounted on the front of the connecting rod. A crank handle is inserted through the outside of the connecting rod. The crank handle is rotatably connected to the rotating plate, the connecting rod, and the baffle. A first knob is mounted on the front of the rotating plate, and a first threaded rod is fixedly mounted on the back of the first knob. A pressure plate is fixedly mounted on the back of the first threaded rod. A transverse groove adapted to the pressure plate is mounted on the back of the rotating plate. The pressure plate is movably connected to the rotating plate through the transverse groove. The first threaded rod passes through the rotating plate into the transverse groove and is threadedly connected to the rotating plate. A rubber anti-slip pad is attached to the side of the pressure plate near the fixed plate.

[0012] In a preferred embodiment, the support mechanism includes a support rod, a fixed cone, a second knob, a vertical groove, a second threaded rod, a lifting block, and an arc-shaped rod. Multiple support rods are arranged above the trolley. A fixed cone is fixedly mounted on the bottom surface of each support rod. A second knob is rotatably connected to the top surface of the support rod. A vertical groove is provided on the outer side of the support rod. A rotating block is fixedly mounted on the bottom surface of the second knob. A second threaded rod is fixedly mounted on the bottom surface of the rotating block. The end of the second threaded rod away from the rotating block is rotatably connected to the support rod via a bearing. A lifting block is threaded through the outer side of the second threaded rod. The second threaded rod is threadedly connected to the lifting block. The left and right sides of the lifting block are slidably connected to the inner wall of the vertical groove, respectively. An arc-shaped rod is fixedly mounted on the front side of the lifting block.

[0013] In a preferred embodiment, a guide ring is fitted around the outer side of the measuring rope, and a fixing rod is fixedly installed at the bottom of the guide ring, with the bottom surface of the fixing rod being fixedly connected to the top surface of the trolley.

[0014] In a preferred embodiment, the top surface of the trolley is fixedly provided with an installation plate and a protective plate, and multiple storage plates are fixedly provided on both the front and rear sides of the installation plate. The top surface of the storage plate is an arc-shaped surface, and a rubber cushioning pad is pasted on the surface of the arc-shaped surface.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model features a rope winding mechanism. The forward and reverse crank can drive the rope winding roller to rotate, thereby extending or winding the measuring rope. This allows for easy adjustment of the extended length of the measuring rope according to measurement needs. When the measuring rope extends to the specified length, rotating the first knob moves the pressure plate close to the fixed plate and, together with the rubber anti-slip pad, presses the fixed plate tightly, preventing the rope winding roller from continuing to rotate. This fixes the position of the end of the measuring rope close to the rope winding roller relative to the trolley, improving the stability of the measuring rope.

[0017] This invention features a support mechanism. When the measuring rope extends to a specified length, the operator installs the support mechanism to insert the fixed cone into the ground. By rotating the second knob, the arc-shaped rod moves up and down until the measuring rope enters the arc-shaped rod, which then supports the rope. This reduces the downward bending of the measuring rope when it is straightened, thus improving measurement accuracy. Attached Figure Description

[0033] Please see the appendix Figure 1 As shown, this utility model provides a wire laying and measuring device, including: a trolley 100, a rope winding mechanism 300 and a support mechanism 400. Self-locking casters 101 are fixedly installed at the four corners of the bottom surface of the trolley 100, a handle 102 is fixedly installed on the top surface of the trolley 100, and a measuring rope 200 is installed above the trolley 100.

[0034] In a preferred embodiment, please refer to Figures 1 to 3The top surface of the trolley 100 is equipped with a rope winding mechanism 300, which consists of a fixed plate 301, a rotating rod 302, a baffle 303, a rope winding roller 304, a rotating plate 305, a connecting rod 306, a baffle 307, a crank handle 308, a first knob 309, a first threaded rod 310, and a pressure plate 311. Symmetrical fixed plates 301 are fixedly installed on the top surface of the trolley 100. A rotating rod 302 extending from the front to the back of the fixed plate 301 is provided. A baffle 302 is fixedly installed on the side of the rotating rod 302 that is close to each other. 03. A rope roller 304 is fixedly installed on one side of the baffle 303 that is close to each other. A rotating plate 305 is fixedly installed on the front of one of the rotating rods 302. A connecting rod 306 is fixedly installed on the front of the rotating plate 305. A baffle 307 is fixedly installed on the front of the connecting rod 306. A crank 308 is provided through the outside of the connecting rod 306. A first knob 309 is provided in front of the rotating plate 305. A first threaded rod 310 is fixedly installed on the back of the first knob 309. A pressure plate 311 is fixedly installed on the back of the first threaded rod 310.

[0035] In this embodiment, the rotating rod 302 is rotatably connected to the fixed plate 301, the baffle 303 is rotatably connected to the fixed plate 301, the outer side of the rope roller 304 is fixedly connected to one end of the measuring rope 200, the outer surface of the crank handle 308 is provided with anti-slip texture, the crank handle 308 is rotatably connected to the rotating plate 305, the connecting rod 306 and the baffle 307 respectively, the back of the rotating plate 305 is provided with a transverse groove adapted to the pressure plate 311, the pressure plate 311 is movably connected to the rotating plate 305 through the transverse groove, the first threaded rod 310 passes through the rotating plate 305 to the inside of the transverse groove and is threadedly connected to the rotating plate 305, and a rubber anti-slip pad is pasted on the side of the pressure plate 311 near the fixed plate 301.

[0036] In this embodiment, the forward and reverse crank 308 can drive the rotating plate 305, connecting rod 306, baffle 307, rotating rod 302, baffle 303 and rope winding roller 304 to rotate along the axis of the rope winding roller 304, thereby extending or winding the measuring rope 200. This allows for easy adjustment of the extended length of the measuring rope 200 according to measurement needs. When the measuring rope 200 extends to the specified length, rotating the first knob 309 causes the pressure plate 311 to approach the fixed plate 301 and, together with the rubber anti-slip pad, press the fixed plate 301 tightly, preventing the rope winding roller 304 from continuing to rotate. This fixes the position of the end of the measuring rope 200 near the rope winding roller 304 relative to the trolley 100, improving the stability of the measuring rope 200.

[0037] In a preferred embodiment, please refer to Figures 1 to 4A support mechanism 400 is provided above the trolley 100. The support mechanism 400 consists of a support rod 401, a fixed cone 402, a second knob 403, a vertical groove 404, a second threaded rod 405, a lifting block 406, and an arc-shaped rod 407. Multiple support rods 401 are provided above the trolley 100. A fixed cone 402 is fixedly provided on the bottom surface of the support rod 401. A second knob 403 is rotatably connected to the top surface of the support rod 401. A vertical groove 404 is provided on the outer side of the support rod 401. A rotating block is fixedly provided on the bottom surface of the second knob 403. A second threaded rod 405 is fixedly provided on the bottom surface of the rotating block. A lifting block 406 is provided through the outer side of the second threaded rod 405. An arc-shaped rod 407 is fixedly provided on the front of the lifting block 406. A notch is provided at the top of the arc-shaped rod 407.

[0038] In this embodiment, the end of the second threaded rod 405 away from the rotating block is rotatably connected to the support rod 401 through a bearing. The second threaded rod 405 is threadedly connected to the lifting block 406. The left and right sides of the lifting block 406 are slidably connected to the inner wall of the vertical groove 404, respectively.

[0039] In this embodiment, when the measuring rope 200 is stretched to a specified length, the worker installs the support mechanism 400 so that the fixed cone 402 is inserted into the ground. The second knob 403 is rotated to drive the rotating block and the second threaded rod 405 to rotate. The rotation of the second threaded rod 405 drives the lifting block 406 to move up and down. The movement of the lifting block 406 drives the arc rod 407 to move up and down until the measuring rope 200 enters the arc rod 407 so that the arc rod 407 supports the measuring rope 200. This reduces the downward bending of the measuring rope 200 when it is straightened, thus improving the measurement accuracy.

[0040] In a preferred embodiment, please refer to Figure 1 A guide ring 500 is fitted on the outer side of the measuring rope 200. A fixing rod 501 is fixedly installed at the bottom of the guide ring 500. The bottom surface of the fixing rod 501 is fixedly connected to the top surface of the trolley 100. The guide ring 500 is used to guide the movement of the measuring rope 200 during the extension and rewinding process, so as to prevent the movement direction of the measuring rope 200 from changing due to the extension and rewinding of the measuring rope 200.

[0041] In a preferred embodiment, please refer to Figure 1 The trolley 100 has a mounting plate 600 and a protective plate 602 fixedly installed on its top surface. Multiple storage plates 601 are fixedly installed on both the front and rear sides of the mounting plate 600. The top surface of the storage plate 601 is curved, and a rubber cushioning pad is attached to the curved surface. The storage plate 601 is used to store the support mechanism 400. The protective plate 602 can prevent the fixing cone 402 from injuring the staff when the support mechanism 400 is stored on the storage plate 601.

[0042] The working principle of this utility is as follows:

[0043] When using the device, the operator pushes the handle 102 to move the trolley 100 to the designated position using the self-locking caster 101. Then, the self-locking caster 101 is locked. Turning the crank 308 causes the rotating plate 305, connecting rod 306, baffle 307, rotating rod 302, baffle 303, and rope winding roller 304 to rotate along the axis of the rope winding roller 304, thereby extending the measuring rope 200. The extension length of the measuring rope 200 is adjusted according to the measurement needs. When the measuring rope 200 extends to the designated length, turning the first knob 309 causes the pressure plate 311 to approach the fixed plate 301 and, with the help of the rubber anti-slip pad, presses the fixed plate 301 tightly, preventing the rope winding roller 304 from continuing to rotate, thus allowing the measuring rope 200 to approach the rope winding roller 304. One end of 04 is fixed relative to the position of the trolley 100 to improve the stability of the measuring rope 200. The operator straightens the measuring rope 200 and removes multiple support mechanisms 400 from the storage plate 601. The operator installs the support mechanisms 400 so that the fixed cone 402 is inserted into the ground. The operator rotates the second knob 403 to drive the rotating block and the second threaded rod 405 to rotate. The rotation of the second threaded rod 405 drives the lifting block 406 to move up and down. The movement of the lifting block 406 drives the arc rod 407 to move up and down until the measuring rope 200 enters the arc rod 407 so that the arc rod 407 supports the measuring rope 200. This reduces the downward bending of the measuring rope 200 when it is straightened, thus improving the measurement accuracy.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
