Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit layout devices, specifically a layout device for measuring building foundation pits. Background Technology

[0002] Foundation pit layout refers to a series of surveying and marking work carried out in construction engineering to determine the specific location of foundation pit excavation and control the excavation depth. After the layout is completed, lime powder is sprinkled to make a clear mark according to the position of the line. It is an important preparatory work before earthwork excavation to ensure that subsequent construction can be carried out in accordance with design requirements.

[0003] A search revealed a Chinese utility model patent, CN 216109807 U, published on March 22, 2022, which proposed a foundation pit layout device for building construction. The patent states that "during the layout work, workers can manually push a first sliding sleeve, which moves a driving rod. A second sliding sleeve, a third sliding sleeve, and a sliding rod further stabilize the driving rod, causing it to move a baffle fixedly connected to its front end. This baffle then moves away from the side of the funnel, allowing lime powder inside the funnel to fall out. This allows for simultaneous layout and lime powder application, solving the problem that existing foundation pit layout devices for building construction mostly require manual layout, followed by marking with lime powder based on the line's position. This is physically demanding, and the lime powder application may be inaccurate, affecting the quality and efficiency of the layout work."

[0004] However, when the sliding block 9 is moved to change the line-laying position, the position of the funnel 14 will also change. At this time, the position of the baffle 20 also needs to be changed to seal the bottom of the funnel 14 to meet the requirements of subsequent use. Furthermore, controlling the movement of the baffle 20 by multiple sliding rods and sleeves will result in insufficient smoothness of the movement of the baffle 20, resulting in insufficient accuracy of the movement of the baffle 20 and inability to quickly seal the bottom of the funnel 14. When the device stops moving, it takes time to move the baffle 20 to seal the bottom of the funnel 14. During the time it takes to adjust the position of the baffle 20, the lime powder stored inside the funnel will be spilled and wasted.

[0005] Therefore, a line-laying device for measuring building foundation pits is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a setting-out device for measuring building foundation pits, so as to solve the problems mentioned in the background art.

A threading plate is fixed between the two threaded sliding plates, and the bottom of the lime funnel is funnel-shaped.

[0008] Preferably, the base is fixed with four casters at its bottom, and the four casters are located at the four corners of the base bottom.

[0009] Preferably, the skateboard assembly includes a skateboard body, and a second slider is welded to each of the two sides of the skateboard body. The second slider is slidably sleeved on the outside of the control rod, and a limiting block is fixedly sleeved on the outside of the control rod.

[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] Example 1: A control rod 14 is welded to one end of the base 1. A slide plate assembly 6 is slidably installed on the outside of the control rod 14. A second support frame 12 is welded to each of the two sides of the top of the base 1. An adjustment assembly 11 is fixed to the top of the two second support frames 12. A lime funnel 13 is slidably installed below the adjustment assembly 11. A rocker arm 10 is rotatably installed on one side of the adjustment assembly 11. A trough 15 is opened inside the base 1. The bottom end of the lime funnel 13 extends into the trough 15. A baffle assembly 3 is installed at the bottom of the base 1. A transmission rope 5 is connected to one end of the baffle assembly 3. One end of the transmission rope 5 is limited and installed inside the slide plate assembly 6. Two guide wheels 4 are installed on one side of the bottom of the base 1. A first support frame 8 is welded to each of the two sides of the top of the base 1. A winding roller 7 is rotatably installed between the two first support frames 8.

[0024] The skateboard assembly 6 includes a skateboard body 601, and a second slider 602 is welded to each side of the skateboard body 601. The second slider 602 is slidably sleeved on the outside of the control rod 14, and a limit stop 604 is fixedly sleeved on the outside of the control rod 14. A pull rod 603 is welded to the top of the skateboard body 601.

[0025] The baffle assembly 3 includes a baffle body 301, a fixing block 302 and a limiting plate 306. There are two fixing blocks 302, which are fixed on both sides of the bottom of the base 1 respectively. The limiting plate 306 is welded to the bottom of the base 1.

[0026] A support slide rod 305 is welded between the fixing block 302 and the limiting plate 306, and a spring 304 is sleeved on the outside of the support slide rod 305.

[0027] A first slider 303 is welded to each side of the baffle body 301, and the first slider 303 is slidably sleeved on the outside of the support slider 305. A connecting plate 307 is welded to one side of the baffle body 301, and one end of the connecting plate 307 is slidably sleeved and extends out of the interior of the limiting plate 306.

[0028] Two limiting rings 308 are welded to one end of the connecting plate 307, and the inside of the limiting rings 308 is limited and installed with one end of the transmission rope 5.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, since the base 1 has a trough 15 inside, and the bottom of the lime funnel 13 slides into the trough 15, after lime powder is injected into the lime funnel 13, the lime powder will leak out from the bottom of the lime funnel 13 and be scattered on the ground through the trough 15. The trough 15 allows the bottom of the lime funnel 13 to slide inside, thus ensuring that the lime powder is leaked and scattered simultaneously when the line laying position is changed. Since the bottom of the base 1 is equipped with a baffle assembly 3, and the baffle assembly 3 includes a baffle body 301 The baffle body 301 can seal the bottom of the trough 15, thereby preventing the lime powder from spilling. When lime powder needs to be sprinkled, the operator can hold the control lever 14 and hook the pull rod 603 with their fingers to drive the slide body 601 to slide upward along the installation direction of the control lever 14. Since there are two transmission ropes 5 fixed inside the slide body 601, and the two transmission ropes 5 pass through the inside of the guide wheel 4 and are fixed inside the limiting ring 308, when the slide body 601 slides upward along the installation direction of the control lever 14... During sliding, the linkage of the transmission rope 5 drives the baffle body 301 to slide along the installation direction of the support slide rod 305 towards the control rod 14. Simultaneously, the first sliders 303 welded to both sides of the baffle body 301 compress the springs 304 sleeved on the outside of the support slide rod 305, controlling the baffle body 301 to slide out from the bottom of the trough 15. At this point, the bottom of the trough 15 is not blocked, and the blockage of the bottom of the lime funnel 13 is also removed. At this time, the lime stored inside the lime funnel 13... The lime powder is then sprinkled out for marking. When the operator stops moving the trolley, they release the hook on the lever 603. At this time, the compressed spring 304 will rebound, pushing the baffle body 301 to the bottom of the trough 15 to seal the bottom of the trough 15 and the lime funnel 13, preventing the lime powder from continuing to spill when the device stops, thus saving the amount of lime powder used. This device can quickly start and stop the lime powder sprinkling operation, making it more convenient and faster to use, and saving the amount of lime powder used.

[0030] The limiting block 604 fixedly sleeved on the outside of the control lever 14 can limit the sliding distance of the skateboard body 601, preventing the skateboard body 601 from sliding to the bottom of the control lever 14, and further facilitating the operator's use.

[0031] Example 2: The adjusting component 11 includes a mounting groove 1101, and a threaded rod 1103 is mounted inside the mounting groove 1101 via a bearing. A threaded sliding plate 9 is welded to each side of the top of the lime funnel 13. The top ends of the two threaded sliding plates 9 slide into the inner wall of the mounting groove 1101, and the two threaded sliding plates 9 are threaded and fitted onto the outside of the threaded rod 1103. A threading plate 1102 is fixed between the two threaded sliding plates 9. The bottom of the lime funnel 13 is funnel-shaped. Four fixed casters 2 are fixed to the bottom of the base 1, and the four fixed casters 2 are located at the four corners of the bottom of the base 1.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, rotating the rocker arm 10 can drive the threaded rod 1103 to rotate. The rotation of the threaded rod 1103 can simultaneously drive the two threaded slide plates 9 to slide along the installation direction of the threaded rod 1103, thereby causing the lime funnel 13 to slide below the mounting groove 1101. Since a threading plate 1102 is fixed between the two threaded slide plates 9, one end of the marking line can be passed through the inside of the threaded rod 1103 and released as the entire device moves. The movement of the lime funnel 13 can simultaneously change the position of the released line and the position of the lime powder, and ensure that the position of the lime powder and the position of the marking line coincide. The marking line can be wound and stored by the winding roller 7. Since a fixed caster 2 is fixed at each of the four corners of the bottom of the base 1, the entire device can be moved easily by the fixed caster 2.

[0033] Working principle: In use, lime powder is injected into the lime funnel 13. Then, one end of the marking line wound on the outside of the winding roller 7 is passed through the inside of the threading plate 1102. Then, by rotating the rocker arm 10, the lime funnel 13 is moved inside the trough 15, changing the position of the marking line and the position of the lime powder. Then, the entire base 1 is moved by the control rod 14 to place the marking line. At the same time, by hooking the pull rod 603 with a finger, the slide body 601 is moved upward along the installation direction of the control rod 14. Since there are two transmission ropes 5 fixed inside the slide body 601, and the two transmission ropes 5 pass through the inside of the guide wheel 4 and are fixed inside the limiting ring 308, when the slide body 601 slides upward along the installation direction of the control rod 14, the linkage of the transmission ropes 5 can drive the baffle body 301 along the support. The sliding rod 305 slides towards the control rod 14. Simultaneously, the first slider 303 welded to both sides of the baffle body 301 compresses the spring 304 sleeved on the outside of the sliding rod 305, controlling the baffle body 301 to slide out from the bottom of the trough 15. At this time, the bottom of the trough 15 will not be blocked, and the bottom of the lime funnel 13 will also be unblocked. At this time, the lime powder stored inside the lime funnel 13 will be spilled out for marking. When the operator stops moving the trolley, the finger releases the hook of the pull rod 603. At this time, the compressed spring 304 will rebound, pushing the baffle body 301 to the bottom of the trough 15 to block the bottom of the trough 15 and the bottom of the lime funnel 13, preventing the lime powder from continuing to spill when the device stops, thus saving the amount of lime powder used.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
