Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering installation, and more specifically, to a civil engineering installation level control device. Background Technology
[0002] In today's complex and ever-changing civil engineering construction environment, topography and foundation conditions can introduce significant uncertainties. When a project progresses to the critical equipment installation stage, ensuring the long-term stable operation of the equipment and its strict compliance with construction specifications hinges on achieving high-precision and efficient control over the installation's levelness. However, regrettably, currently widely used conventional levelness control devices generally exhibit the dual bottlenecks of low adjustment efficiency and insufficient observation accuracy in practical operation.
[0003] Specifically, on the one hand, traditional devices mostly rely on mechanical nuts for fine-tuning. This adjustment method is not only extremely cumbersome and lengthy, but also, due to the minute nature of the nut's travel, operators often need to spend a significant amount of time performing repeated, meticulous, and mentally taxing adjustments to barely achieve the preset horizontal accuracy. This not only greatly slows down the installation progress but also significantly increases labor and time costs, making it difficult to improve overall construction efficiency.
[0004] On the other hand, existing technologies for determining levelness primarily rely on observing the position of the bubble in a simple level. This visual observation method is limited by multiple factors, including insufficient bubble sensitivity, parallax interference, and differences in operator subjective judgment. Its inherent observation error range is relatively large, often failing to meet the stringent levelness requirements of modern precision equipment installation. Even minor deviations can be amplified during long-term equipment operation, thereby affecting equipment performance stability and even structural safety.
[0005] In conclusion, given the increasingly stringent demands for efficiency and precision in current civil engineering construction, the limitations of existing leveling control devices have become increasingly apparent. Therefore, developing a novel leveling control device capable of overcoming these bottlenecks and achieving rapid, precise adjustment and highly reliable judgment has become an urgent technical requirement for improving the quality of civil engineering equipment installation, accelerating overall construction efficiency, and reducing overall costs. Utility Model Content
[0006] To overcome the aforementioned shortcomings of existing technologies, this utility model provides a civil engineering installation level control device. This device enables high-precision and high-efficiency control of installation level, ensuring long-term stable operation of equipment and strict compliance with construction specifications. It not only significantly improves installation level accuracy and reduces the technical requirements for operators, but also greatly enhances construction efficiency, guarantees the overall quality of civil engineering installation, and is conducive to promoting industry development and technological progress, possessing broad application prospects.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A civil engineering installation level control device includes a base, a support rod, a guide column, a gravity pointer angle meter, a laser positioning drive assembly, a limiting assembly, and a quick-fixing assembly. The base has an internal groove with a counterweight installed within it. A support rod is mounted on the side wall of the base. The guide column is hinged to the support rod. The gravity pointer angle meter and the laser positioning drive assembly are mounted on the guide column, with the laser positioning drive assembly positioned above the gravity pointer angle meter. The limiting assemblies are located on both sides of the bottom end of the guide column, and the guide column is connected to the base via the limiting assemblies. The quick-fixing assembly is located on the side wall of the limiting assembly.
[0008] The gravity pointer angle meter includes an angle disk, a rotating shaft, and a gravity pointer. The zero mark of the angle disk is parallel to the guide column. The angle disk is fixed to the side wall of the guide column. The gravity pointer is set on the side wall of the angle disk through the rotating shaft, and the gravity pointer can rotate around the rotating shaft.
[0009] The laser positioning drive assembly includes a moving box, a motor, a gear, and a laser emitter. The laser emitter is disposed on the side wall of the moving box, the motor is disposed inside the moving box, the output end of the motor is fixedly connected to the gear, and a rack is disposed at the rear end of the guide post in the vertical direction. The gear meshes with the rack at the rear end of the guide post.
[0010] The limiting assembly includes a connecting rod, a first spring, a limiting post, and a fixing tooth. One end of the connecting rod is hinged to the guide post, and one end of the limiting post is hinged to the base. The end of the connecting rod away from the guide post is movably inserted into the limiting post. The two ends of the first spring are respectively connected to the inside of the connecting rod and the limiting post. The fixing tooth is fixedly installed at the upper end of the limiting post.
[0011] The quick-fixing assembly includes a slide, a second spring, a bite frame, and bite teeth. Two sets of slides are symmetrically arranged on both sides of the connecting rod. The bite frame is a concave frame, with both ends of the bite frame movably inserted into the slide. Both ends of the second spring are connected to the slide and the bite frame, respectively. The bite teeth are fixedly arranged on the lower surface of the bite frame and are engaged with the fixed teeth.
[0012] The side wall of the limiting column is provided with a slot that matches the slide, and the slide slides along the connecting rod through the slot.
[0013] The carriage adopts an L-shaped structure, and the top of the carriage has a movable groove that matches the structure at both ends of the engagement frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a gravity pointer angle meter as its core component. Compared to traditional bubble level meters, its gravity pointer more sensitively and intuitively reflects the ground tilt angle, improving the accuracy of levelness judgment. Simultaneously, combined with a laser emitter, a precise laser beam provides an intuitive positioning baseline, doubly ensuring high-precision control of installation levelness. The laser positioning drive assembly, utilizing a combination of a motor and rack and pinion, enables rapid adjustment of the laser emitter height, eliminating the need for traditional manual adjustment with nuts, simplifying operation, saving effort, improving adjustment efficiency, and shortening installation time.
[0015] The guide column's hinged connection to the base via a support rod allows for flexible rotation of the entire guide structure, greatly enhancing the device's adaptability to complex or uneven installation surfaces. Through the synergistic action of the limiting and quick-locking components, after the guide column is rotated to the desired angle, the engagement frame allows for easy one-handed operation. This enables the engagement teeth to instantly disengage from the fixing teeth, releasing the limiting mechanism. Releasing the engagement frame allows the engagement and fixing teeth to re-engage and lock, quickly and reliably fixing the guide column angle. This achieves one-button quick fixing and unlocking during operation, ensuring convenient and safe operation and effectively preventing accidental movement. The device's rational structural design, combining the flexible rotation of the guide column with the quick-locking mechanism, significantly reduces the technical requirements for operator skill, improves the levelness control accuracy and construction efficiency of civil engineering equipment installation, and ensures the long-term stability and safety of the equipment.

Detailed Implementation
[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0020] like Figures 1 to 4 As shown, a civil engineering installation level control device includes a base 1, a support rod 2, a guide column 3, a gravity pointer angle meter, a laser positioning drive assembly, a limiting assembly, and a quick-fixing assembly. The base 1 has a groove inside, and a counterweight is installed in the groove. The support rod 2 is provided on the side wall of the base 1. The guide column 3 is hinged to the support rod 2. The gravity pointer angle meter and the laser positioning drive assembly are provided on the guide column 3. The laser positioning drive assembly is provided above the gravity pointer angle meter. The limiting assembly is provided on both sides of the bottom end of the guide column 3. The guide column 3 is connected to the base 1 through the limiting assembly. The quick-fixing assembly is provided on the side wall of the limiting assembly.
[0021] Preferably, a fixed counterweight is provided inside the base 1 to provide stability to the overall structure. The support rod 2 is fixedly installed on the side wall of the base 1, and the guide column 3 is hinged to the support rod 2 and can rotate around the hinge axis to adjust the angle.
[0022] Preferably, the gravity pointer angle gauge includes an angle disk 4, a rotating shaft 5, and a gravity pointer 6. The zero mark of the angle disk 4 is parallel to the guide post 3. The angle disk 4 is fixed to the side wall of the guide post 3. The gravity pointer 6 is set on the side wall of the angle disk 4 through the rotating shaft 5, and the gravity pointer 6 can rotate around the rotating shaft 5. When the gravity pointer 6 does not point to the zero mark of the angle disk 4, it indicates that there is an angular deviation in the guide post 3. At this time, the guide post 3 needs to be rotated according to the scale indication of the angle disk 4 until the gravity pointer 6 points to the zero mark again to complete the horizontal adjustment.
[0023] Preferably, the laser positioning drive assembly includes a moving box 7, a motor 8, a gear 9, and a laser emitter 10. The laser emitter 10 is disposed on the side wall of the moving box 7, and the motor 8 is disposed inside the moving box 7. The output end of the motor 8 is fixedly connected to the gear 9. A rack is disposed at the rear end of the guide column 3 in a vertical direction. The gear 9 meshes with the rack at the rear end of the guide column 3. When the control button on the moving box 7 is pressed, the motor 8 is started to drive the gear to rotate. The gear 9 meshes with the rack structure at the rear end of the guide column 3, causing the moving box 7 to move up and down along the guide column 3. When the laser emitter 10 moves to the preset position, the laser emitter 10 is turned on to emit a laser beam, providing the operator with a reference line for equipment installation.
[0024] Preferably, the limiting assembly includes a connecting rod 11, a first spring 12, a limiting post 13, and a fixing tooth 14. One end of the connecting rod 11 is hinged to the guide post 3, and one end of the limiting post 13 is hinged to the base 1. The end of the connecting rod 11 away from the guide post 3 is movably inserted into the limiting post 13. The two ends of the first spring 12 are respectively connected to the interior of the connecting rod 11 and the limiting post 13. The fixing tooth 14 is fixedly set at the upper end of the limiting post 13. One end of the connecting rod 11 is connected to the guide post 3. When the guide post 3 is rotated, the connecting rod 11 is driven to produce a telescopic movement. The first spring 12 applies an elastic force to the guide post 3, and the limiting post 13 mechanically limits the rotation angle of the guide post 3 to prevent it from moving freely.
[0025] Preferably, the quick-fixing assembly includes a slide 15, a second spring 16, a bite frame 17, and bite teeth 18. The slide 15 has two sets symmetrically arranged on both sides of the connecting rod 11. The bite frame 17 is a concave frame, and both ends of the bite frame 17 are movably inserted into the slide 15. The two ends of the second spring 16 are respectively connected to the slide 15 and the bite frame 17. The bite teeth 18 are fixedly arranged on the lower surface of the bite frame 17. The bite teeth 18 are engaged with the fixed teeth 14. Lifting the bite frame 17 moves it upward, so that the bite teeth 18 at the bottom of the bite frame 17 disengage from the fixed teeth 14 at the top of the limiting post 13. After rotating the guide post 3 to the required angle position, the bite frame 17 is released. Under the restoring force of the second spring 16, the bite frame 17 drives the bite teeth 18 to return downward and re-engage with the fixed teeth 14, thus completing the locking of the guide post 3.
[0026] Preferably, the side wall of the limiting post 13 is provided with a slot that matches the slide 15, and the slide 15 slides with the connecting rod 11 through the slot.
[0027] Preferably, the carriage 15 adopts an L-shaped structure, and the top of the carriage 15 is provided with a movable groove that matches the structure at both ends of the engagement frame 17.
[0028] During civil construction, the device is securely placed on the construction surface using the counterweights inside the base 1. After stable placement, observe the gravity pointer angle gauge: the gravity pointer 6 always points vertically under the influence of gravity, and the scale value indicated by its tip on the angle dial 4 reflects the tilt angle of the guide column 3 relative to the horizontal plane. If the gravity pointer 6 does not point to the zero mark, the angle of the guide column 3 needs to be adjusted. During adjustment, the operator pulls the engagement frame 17 upwards, and the engagement frame 17 moves upwards against the elastic force of the second spring 16, causing the engagement teeth 18 at the bottom of the engagement frame 17 to disengage from the fixing teeth 14 at the top of the limiting column 13, thus releasing the locking state of the guide column 3. Subsequently, rotate the guide column 3 to the desired angle. During this rotation, the connecting rod 11 hinged to the bottom of the guide column 3 extends and retracts, simultaneously stretching or compressing the first spring 12. The reverse tension generated by the first spring 12 helps stabilize the position of the guide column 3. When the gravity pointer 6 is observed to re-stable and point to the zero mark of the angle dial 4, it indicates that the guide column 3 has been adjusted to be horizontal. At this point, release the engagement frame 17. Under the restoring force of the second spring 16, the engagement frame 17 drives the engagement teeth 18 to return downwards and re-engage tightly with the fixed teeth 14, quickly locking the guide post 3 at the adjusted angle position. After the angle is locked, start the laser positioning drive assembly: press the control button on the moving box 7, and the motor 8 drives the gear 9 to rotate. Since the gear 9 meshes with the rack structure at the rear end of the guide post 3, the rotation of the gear 9 will drive the moving box 7 to rise and fall along the guide post 3. After the laser emitter 10 moves to the precise height required for construction, stop the motor 8 and turn on the laser emitter 10. The reference laser beam projected by the laser emitter 10 provides the operator with a precise installation positioning reference line. The operator can then use this laser beam to perform the equipment installation. Repeat the above adjustment and positioning operations until all relevant equipment is installed and reaches the required level.
[0029] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
