Description

Technical Field

[0001] This utility model relates to the field of high-altitude construction measurement technology, and in particular to an adaptive high-altitude length measurement device. Background Technology

[0002] In the field of high-altitude surveying, especially for structures such as cable trays and pipes, numerous challenges have long existed. Traditional surveying methods rely on ground-based measurements or the use of scaffolding, ladders, and other auxiliary tools for high-altitude work. These methods are not only inefficient but also pose safety hazards. Particularly during electromechanical installation, visual inspection from the ground is often insufficient for cable trays and pipes installed on slabs or high-rise structures, while high-altitude work is further hampered by operational difficulties and environmental limitations, making measurement even more challenging. Furthermore, traditional surveying methods are ill-suited for structures with unusual shapes, such as curved pipes.

[0003] While some high-altitude surveying tools exist on the market, they often lack flexibility and adaptability, failing to meet diverse measurement needs. For example, existing measuring devices may not be suitable for pipes and cable trays of different diameters or shapes, or require frequent adjustments during operation, increasing workload and time costs. Furthermore, in cable material planning and settlement processes, discrepancies between on-site installation and drawings lead to deviations in measurement results from actual requirements, affecting the accuracy and efficiency of projects. Therefore, there is an urgent need for an adaptive measuring device capable of adapting to different high-altitude environments, shapes, and sizes.

[0004] Solving the aforementioned technical problems is the challenge facing this utility model. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rationally designed, safe, and reliable adaptive high-altitude length measuring device. Through the coordinated operation of components such as a handheld rod, a telescopic base, a movable base, and a measuring base, it achieves efficient and accurate measurements. The measuring base is equipped with a roller counter and an adjustable clamping mechanism, enabling it to adapt to pipes or cable trays of different sizes and shapes, thus improving the convenience and accuracy of measurements.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an adaptive high-altitude length measuring device, including a handheld rod, a telescopic base frame provided on the handheld rod, a movable base frame that slides with the telescopic base frame on the telescopic base frame, a positioning screw that cooperates with the movable base frame on the telescopic base frame, and a measuring base on the movable base frame;

[0007] The measuring base is equipped with a roller counter, and two clamping plates are symmetrically arranged on the measuring base. The clamping plates are equipped with sliding plates that cooperate with the measuring base. The measuring base is equipped with a synchronous drive assembly for controlling the two clamping plates to move towards each other or relative to each other. The handheld lever is equipped with a drive control assembly for driving the synchronous drive assembly.

[0008] Preferably, two structural designs for synchronous drive components are provided, and the structural designs for corresponding drive control components are carried out for each of the structural designs of synchronous drive components.

[0009] In the first structural design, the measuring base has a sliding groove that slides with the sliding plate, the synchronous drive assembly includes an electronically controlled drive unit disposed on the measuring base, and the drive control assembly includes a battery pack disposed in the hand handle, and the battery pack is electrically connected to an electronically controlled knob for controlling the electronically controlled drive unit.

[0010] The electronically controlled drive unit includes a drive base groove disposed in the measuring base, a synchronous gear disposed in the measuring base groove, two guide grooves symmetrically disposed on the measuring base, a transmission rack disposed in the guide groove that meshes with the synchronous gear and is fixedly connected to the slide plate, and a drive motor disposed on the measuring base that is connected to the synchronous gear and electrically connected to the electronically controlled rotation.

[0011] In the second structural design, the synchronous drive assembly includes a mechanical transmission unit disposed on the measuring base, and the drive control assembly includes a mechanical control unit disposed on the handgrip and cooperating with the mechanical transmission unit.

[0012] Furthermore, the mechanical transmission unit includes a synchronization frame disposed between the measuring base and the movable base. A sliding frame is provided on the synchronization frame. The length direction of the sliding frame is parallel to the sliding direction of the slide plate. Two drive brackets are symmetrically arranged in the sliding frame, which slide in cooperation with the sliding frame and are fixedly connected to the slide plate.

[0013] A drive sleeve is fitted on the movable base frame, which slides and cooperates with the mechanical control unit. Two drive links are symmetrically arranged on the drive sleeve. One end of the drive link is rotatably connected to the drive bracket, and the other end of the drive link is rotatably connected to the drive sleeve.

[0014] Preferably, a limiting groove is vertically formed on the movable base frame, and a limiting screw is provided on the drive sleeve, with limiting nuts provided at both ends of the limiting screw; in use, the limiting screw passes through the limiting groove.

[0015] The mechanical control unit includes a fixed plate disposed on the hand handle. A limiting winch is disposed in the fixed plate and is rotatably connected to the fixed plate. A hinged rope is disposed in the limiting winch and is fixedly connected to the mechanical transmission unit. A limiting plate is disposed at one end of the limiting winch near the fixed plate. A limiting rod is disposed on the limiting plate and cooperates with the fixed plate. A plurality of fixing grooves cooperating with the limiting rod are evenly disposed along the circumferential direction of the fixed plate.

[0016] This invention, equipped with a retractable handheld pole and a movable base, can be easily adjusted to different measuring heights and positions, making it suitable for measuring the length of various high-altitude cable trays, pipes, and curved pipes. Compared with traditional measurement methods that rely on scaffolding or A-frame ladders, it is simpler to operate and greatly improves measurement efficiency, especially in complex high-altitude environments, reducing cumbersome steps and required auxiliary tools during the measurement process.

[0017] This invention employs two different synchronous drive component structures, comprising an electronically controlled drive unit and a mechanical transmission unit. The electronically controlled drive unit uses an electronically controlled knob to control a transmission rack or belt, achieving precise synchronous movement of the clamping plate and ensuring the accuracy of the measurement data. The mechanical transmission unit, through mechanical control components such as a limit winch linked to the drive bracket, ensures high-precision measurement even without power. The different drive component designs enable the device to provide reliable measurement results in various working environments, enhancing its adaptability and measurement accuracy.

[0018] This invention is applicable to the measurement of different types of pipes and cable trays, including straight and curved sections, solving the problem that traditional measuring tools struggle to handle complex shapes and structures. Through its adjustable clamping plate and sliding plate design, it can adapt to measuring objects of different diameters and shapes, ensuring the accuracy and consistency of measurement data and meeting diverse engineering measurement needs. This wide applicability makes the device highly valuable in various building construction and electromechanical installation projects. Attached Figure Description

[0026] The measuring base 300 is provided with a roller counter 400, and two clamping plates 310 are symmetrically arranged on the measuring base 300. The clamping plates 310 are provided with a sliding plate 320 that cooperates with the measuring base 300. The measuring base 300 is provided with a synchronous drive component 500 for controlling the two clamping plates 310 to move towards each other or relative to each other. The handheld lever 100 is provided with a drive control component 600 for driving the synchronous drive component 500.

[0027] Specifically, the handheld lever 100 is easy for the operator to hold, the movable base 210 can slide on the telescopic base 200 to adapt to different measurement positions, and the positioning screw 220 is used to lock the position of the movable base 210 to ensure the stability of the measuring base 300. The height can be adjusted by stretching or retracting to ensure that the measuring base 300 can contact pipes or cable trays of different heights. The rollers in the roller counter 400 on the measuring base 300 move along the pipe or cable tray with the measuring base 300; their rotation triggers the counter to record the travel distance, thereby measuring the actual length of the pipe or cable tray. The clamping plate 310 is used to fix the pipe or cable tray to ensure stability during the measurement process; the synchronous drive assembly 500 is used to control the synchronous movement of the clamping plate 310, while the drive control assembly 600 provides the power source and controls the operation of the synchronous drive assembly 500.

[0028] Preferably, two structural designs for synchronous drive components 500 are provided, and the structural design of the corresponding drive control component 600 is carried out for each of the structural designs of synchronous drive components 500.

[0029] In the first structural design, the measuring base 300 is provided with a sliding groove that slides with the sliding plate 320. The synchronous drive assembly 500 includes an electronically controlled drive unit disposed on the measuring base 300.

[0031] Specifically, the electronically controlled drive unit automatically controls the clamping plate 310 to adapt to the measurement needs of different pipe diameters and shapes. The measuring base 300 has a sliding groove, and the sliding plate 320 slides within the groove. A synchronous gear is installed in the drive groove, and a transmission rack meshing with the synchronous gear is fixed to the sliding plate 320. The drive motor drives the synchronous gear to rotate, which in turn drives the transmission rack, achieving synchronous movement of the clamping plate 310. The drive control component 600 provides the power source and controls the operation of the synchronous drive component 500. The battery pack in the handheld lever 100 supplies power to the electronically controlled drive unit. The electronically controlled knob controls the operating status of the electronically controlled drive unit, i.e., controls the start, stop, and direction of the drive motor.

[0032] In addition, the synchronous drive unit may also be configured as follows: including a synchronous drive wheel, a rotating wheel symmetrically arranged on the measuring base 300, and a transmission belt or transmission chain respectively connected to the two slide plates 320 and cooperating with the synchronous drive wheel and the rotating wheel; the synchronous drive unit may also be configured as follows: including a transmission screw, and a transmission seat meshing with the transmission screw and respectively connected to the two slide plates 320.

[0033] In the second structural design, the synchronous drive assembly 500 includes a mechanical transmission unit disposed on the measuring base 300, and the drive control assembly 600 includes a mechanical control unit disposed on the handheld lever 100 and cooperating with the mechanical transmission unit.

[0034] Furthermore, the mechanical transmission unit includes a synchronization frame 510 disposed between the measuring base 300 and the movable base. A sliding frame 520 is provided on the synchronization frame 510. The length direction of the sliding frame 520 is parallel to the sliding direction of the slide plate 320. Two drive brackets 530 are symmetrically arranged in the sliding frame 520, which slide in cooperation with the sliding frame 520 and are fixedly connected to the slide plate 320.

[0035] A drive sleeve 540 is fitted on the movable base 210, which slides with the movable base 210 and cooperates with the mechanical control unit. Two drive links 550 are symmetrically arranged on the drive sleeve 540. One end of the drive link 550 is rotatably connected to the drive bracket 530, and the other end of the drive link 550 is rotatably connected to the drive sleeve 540.

[0036] Preferably, a limiting groove 211 is vertically formed on the movable base frame 210, and a limiting screw 560 is provided on the drive sleeve 540. A limiting nut 570 is provided at both ends of the limiting screw 560. In use, the limiting screw 560 passes through the limiting groove 211.

[0037] The mechanical control unit includes a fixed plate 610 disposed on the hand handle 100. A limiting winch 620 rotatably connected to the fixed plate 610 is disposed in the fixed plate 610. A hinged rope 630 fixedly connected to the mechanical transmission unit is disposed in the limiting winch 620. A limiting plate 640 is disposed at one end of the limiting winch 620 near the fixed plate 610. A limiting rod 650 cooperating with the fixed plate 610 is disposed on the limiting plate 640. A plurality of fixing grooves 660 cooperating with the limiting rods 650 are evenly disposed along the circumferential direction of the fixed plate 610.

[0038] Specifically, the hinge rope 630 is located on the outside of the telescopic base frame 200 and the movable base frame 210, and the hinge rope 630 is fixedly connected to the aforementioned drive sleeve 540; when the telescopic base frame 200 and the movable base frame 210 are hollow, the hinge rope 630 is located in the telescopic base frame 200 and the movable base frame 210, and the hinge rope 630 is fixedly connected to the aforementioned limiting screw 560.

[0039] Specifically, the second structural design uses mechanical means to control the synchronous movement of the clamping plate 310, ensuring that measurement operations can still be performed without power support. This provides a synchronous drive method that does not require electricity in high-altitude working environments where power is inconvenient. The mechanical transmission unit includes a synchronous frame 510 installed between the measuring base 300 and the movable base 210. The synchronous frame 510 has a sliding frame 520, and a drive bracket 530 is slidably fitted inside the sliding frame 520. The drive bracket 530 is fixedly connected to the slide plate 320 and connected to the drive sleeve 540 through a drive linkage 550. When the drive sleeve 540 moves, it drives the drive bracket 530 through the drive linkage 550, thereby driving the slide plate 320 and realizing the synchronous movement of the clamping plate 310. The drive control component 600 controls the movement of the synchronous drive component 500. The limiting winch 620 in the fixed plate 610 is connected to the mechanical transmission unit through a hinge rope 630. When the limiting winch 620 rotates, it controls the movement of the drive sleeve 540 through the hinge rope 630. The limiting rod 650 on the limiting plate 640 cooperates with the fixing groove 660 on the fixing plate 610 to limit the rotation angle of the limiting winch 620 and achieve precise control.
