Description

Technical Field

[0001] The utility model relates to a positioning device, in particular to a positioning device used for auxiliary measurement during assembly of prefabricated parts. Background Art

[0002] During the installation of traditional prefabricated pipe culverts and various types of structural components, measurement and positioning are usually carried out manually by visually inspecting the construction lines. This method not only requires multiple manual measurements and adjustments of the position and slope, resulting in slow progress and low efficiency, but also manual measurement is prone to large errors. In the actual construction process, before the traditional prefabricated parts are spliced ​​and installed, construction lines are first hung on both sides of the installation for positioning, and then the construction lines are manually used for repeated visual inspection and manual alignment. The entire implementation process suffers from the following problems: workers have to perform a lot of repetitive work, which is inefficient and requires a long cycle of repeated operations; manual visual positioning and alignment have large errors; and labor costs are wasted, which is uneconomical. Utility Model Content

[0003] To address these shortcomings, the present invention provides a simple measurement and positioning device consisting of two independent parts: a fixed positioning device containing an electronic slope meter and a laser transmitter, fixed to the starting end of the prefabricated culvert; and a mobile measurement and positioning device that can be flexibly disassembled and subsequently used to perform mobile measurement and positioning of prefabricated components to be installed. This device avoids the problems of repeated adjustments and large positioning and measurement errors that occur during actual construction.

[0004] Specifically, the utility model provides a measuring and positioning device, including a fixed positioning device and a mobile measuring and setting device, wherein the fixed positioning device and the mobile measuring and setting device respectively include a positioning bracket, wherein the positioning bracket includes a front bracket and a rear bracket, and the front bracket and the rear bracket have the same structure, wherein the front bracket includes a vertical left leg and a right leg, and a left cross arm perpendicular to the left leg, and a right cross arm perpendicular to the right leg, wherein a telescopic arm that can slide freely laterally is provided on the left cross arm and the right cross arm;

[0005] The telescopic arm is a hollow structure. When it moves toward the left and right cross arms, the length of the left and right cross arms can be extended. A connecting arm is provided between the telescopic arms of the left and right cross arms. A level ruler is vertically arranged between the connecting arms of the front and rear brackets. The level ruler is used to determine the horizontal direction of the positioning bracket. An electronic incline meter is also fixed above the level ruler to determine the slope of the positioning bracket. Fixing bolts are oppositely provided on the left and right legs. Tightening the fixing bolts relative to each other can clamp the fixing positioning device to the prefabricated part.

[0006] The fixed positioning device includes a positioning bracket and a laser emitter fixed on the connecting arm of the front bracket of the positioning bracket; the mobile measurement and setting device consists of a positioning bracket and a laser target fixed on the connecting arm of the front bracket of the positioning bracket.

[0007] Furthermore, the laser emitter is fixed to the connecting arm by screws or fastening bolts; the laser target is fixed to the connecting arm by screws or fastening bolts.

[0008] Furthermore, the left and right telescopic arms are respectively provided with transverse grooves that cooperate with the slide rails on the left and right cross arms, so that the telescopic arms can move along the slide rails.

[0009] Furthermore, a drive motor is fixedly installed below the left cross arm, and the drive motor is used to drive the screw to rotate. The screw extends into the interior of the telescopic arm, and a nut is provided at one end of the telescopic arm. The nut cooperates with the screw to form a screw-nut device. When the drive motor drives forward and reverse, the nut drives the telescopic arm to move forward and backward along the screw to adjust the length of the telescopic arm and provide pre-tightening force to the positioning bracket.

[0010] Furthermore, the right cross arm is also provided with a screw drive system as described for the left cross arm.

[0011] This utility model is suitable for the splicing and installation of prefabricated pipe culvert components and masonry materials of various materials and shapes, and features simultaneous measurement and auxiliary installation positioning. It consists of a fixed positioning device and a mobile measurement and installation device. The difference between the two devices is that one has a laser emission system, while the other has a target receiving system. Each device further comprises a fixed system (including a level), a laser emission system (or a target receiving system), and a slope positioning system. This patented utility model utilizes an auxiliary device to transform the traditional manual positioning of prefabricated pipe culverts using construction line meshing into automated instrumental measurement and positioning. This improves the measurement and positioning accuracy of the prefabricated pipe culvert splicing process, saves manpower, reduces construction time, improves work efficiency, ensures project completion, and reduces costs.

[0012] The advantages of the utility model are:

[0013] 1. Wide range of applications. This device is not only suitable for the installation of common square and round prefabricated parts, but also for the installation, positioning, and auxiliary measurement of prefabricated parts of various shapes. In addition, the horizontal width of this device can be adjusted to accommodate the installation and auxiliary positioning of prefabricated parts of different sizes.

[0014] 2. Simple installation and operation. The device is easy to install and operate. It can be installed manually. After installation and debugging, you only need to turn on the laser device to perform measurement and positioning.

[0015] 3. Cost saving: Using this device for prefabricated parts splicing construction does not require a lot of time for adjustment, which improves work efficiency and saves labor costs.

[0016] 4. High measurement accuracy. This device uses a level, an electronic slope meter, and a laser to complete measurement and positioning. It has high measurement accuracy and avoids the large errors caused by manual visual inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4The figure shows a schematic diagram of the structure of the positioning bracket of the measuring and positioning device of the present invention. The positioning bracket includes a front bracket and a rear bracket. The front bracket and the rear bracket have the same structure. Now, taking one of them as an example, its structure is described. The front bracket includes a vertical left leg 11 and a right leg 12, as well as a left cross arm 13 perpendicular to the left leg 11 and a right cross arm 14 perpendicular to the right leg 12. A telescopic arm 7 that can slide freely laterally is mounted on the left cross arm 13 and the right cross arm 14. The telescopic arm 7 is provided with a transverse groove, for example, to cooperate with the slide rails on the left and right cross arms, so that the telescopic arm 7 can move along the slide rails. The telescopic arm 7 is a hollow structure. When it moves toward the left and right cross arms, the length of the left and right cross arms can be extended. A connecting arm 15 is provided between the telescopic arms 7 of the left and right cross arms. A level 5 is vertically arranged between the connecting arms 15 of the front and rear brackets. The level 5 is used to determine the horizontal direction of the positioning bracket. An electronic incline meter 4 is also fixed above the level 5 to determine the slope of the positioning bracket. The device also includes opposing height-fixing devices 2 located on the left and right legs 11, 12. These devices are designed to be secured above the prefabricated component. In one embodiment, these devices can move up and down along the left and right legs to adjust the relative height of the connecting arm 15 and the prefabricated component. The height-fixing devices 2 can also be directly secured to the legs by welding. Opposing fixing bolts 3 are located on the left and right legs. Tightening these fixing bolts secures the positioning device to the prefabricated component.

[0023] The prefabricated component assembly auxiliary measurement and positioning device of the present invention comprises a fixed positioning device and a mobile measurement and positioning device. The fixed positioning device comprises a positioning bracket and a laser emitter 6 fixed to a connecting arm 15 of the positioning bracket's front bracket. The laser emitter is secured to the connecting arm 15, for example, by screws. The mobile measurement and positioning device comprises a positioning bracket and a laser target 1 fixed to the connecting arm 15 of the positioning bracket's front bracket. The laser target 1 is secured to the connecting arm 15, for example, by screws or fastening bolts.

[0024] Before use, install a section of prefabricated parts with accurate position and slope. Use the first section of prefabricated parts as a reference point, install the fixed positioning device on the first section of prefabricated parts, and use the spirit level 5 and electronic incline meter 4 provided by the fixed positioning device to perform horizontal leveling and longitudinal slope verification. After ensuring the accuracy of its position, tighten the fixing bolts 3 and use the laser transmitter 6 to provide an accurate reference line for subsequent prefabricated part installation.

[0025] The subsequent prefabricated component installation and positioning procedure involves installing the mobile measuring device on the next prefabricated component to be assembled. Using the mobile measuring device's built-in level 5 and electronic incline meter 4, the transverse leveling and longitudinal slope of the prefabricated component to be installed are measured. The laser target 1, from which the laser beam emitted by the fixed positioning device is centered, allows for real-time verification of the reference point. Once longitudinal centering, transverse leveling, and longitudinal slope meet the requirements, the prefabricated component is deemed to have been properly installed. The mobile measuring device is then removed, and the process is repeated to proceed with the installation of the next prefabricated component. This process continues until all prefabricated components are installed.

[0026] By adjusting the telescopic arm and the connecting arm of the positioning bracket, the lateral width of the positioning bracket can be adjusted to accommodate the installation of prefabricated parts of different sizes.

[0027] refer to Figure 4 Taking the left cross arm 13 of the positioning bracket as an example, a slide rail is provided on the left cross arm 13, and a groove 19 is provided on the telescopic arm 7. The groove 19 cooperates with the slide rail and can move freely on the slide rail. A drive motor 16 is fixedly provided under the left cross arm. The drive motor 16 is used to drive the screw rod 18 to rotate. The screw rod 18 extends into the interior of the telescopic arm 7. A nut 17 is provided at one end of the telescopic arm 7. The nut 17 cooperates with the screw rod 18 to form a screw nut device. When the drive motor 16 drives forward and reverse, the nut 17 drives the telescopic arm 7 to move forward and backward along the screw rod 18, thereby adjusting the length of the telescopic arm 7 and providing pre-tightening force to the positioning bracket.

[0028] The right cross arm may also be provided with a screw drive system as described for the left cross arm.

[0029] When fixing the positioning bracket to the prefabricated part, first control the rotation of the drive motor 16 through the remote control, thereby extending the telescopic arm so that the positioning bracket can be easily engaged with the prefabricated part, and then control the drive motor 16 to rotate so that the distance between the left and right telescopic arms 7 is shortened, thereby providing a pre-tightening force to the positioning bracket, making it convenient to fine-tune the positioning bracket for lateral leveling and longitudinal slope calibration. After the fine-tuning is completed, tighten the fixing bolt 3, thus completing the entire installation of the positioning bracket.

[0030] The utility model is applicable to prefabricated parts of various materials and shapes. The shape of the fixing frame can be changed with the shape of the material, which all fall within the protection scope of the utility model.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
