Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation and measurement devices, in particular to a portable elevator installation and measurement device. Background Art

[0002] Publication No. CN206692166U discloses a device for measuring the installation spacing of elevator guide rail brackets. The device comprises a main unit mounted on the top of the elevator car or counterweight, an encoder mounted on the elevator guide rail, and a proximity switch mounted on the elevator guide rail bracket or sunshade. The main unit is wired to the encoder and proximity switch. The main unit is equipped with a single-chip microcomputer controller, a rechargeable lithium battery pack, a thermal printer, and a liquid crystal touch screen display. Charging cables are provided between the rechargeable lithium battery pack, the encoder, and the proximity switch. The encoder is equipped with an infrared sensor. This device can easily and conveniently measure the spacing between all elevator guide rail brackets at once, automatically assessing whether the installation of the elevator guide rail brackets meets inspection and regulatory requirements. Conventional elevator installation measurement devices suffer from significant deficiencies in portability and flexibility. Most conventional devices utilize a relatively fixed structural design, resulting in a large size that is not easily portable on-site. Storage and transportation are particularly inconvenient, especially in confined spaces or complex working conditions. Furthermore, the device lacks flexibility, making it difficult to quickly adapt to different measurement scenarios. Operation in complex environments is cumbersome, impacting work efficiency. The overall design fails to meet high requirements in terms of operational convenience and space utilization, which brings certain burdens to users and needs to be improved. Utility Model Content

[0021] Example 1

[0022] See also Figure 1-4The utility model provides a technical solution: a portable elevator installation measuring device, comprising a shell 1, a screw rod 3 is rotatably connected to the interior of the shell 1, and a scale rod 4 is threadedly connected to the surface of the screw rod 3, and a rotating head 5 is fixedly installed at one end of the screw rod 3, and the side of the shell 1 is rotatably connected to the rotating frame 6. The measuring rod 7 is slidably connected to the interior of the rotating frame 6, and a limit block 8 is fixedly installed on one end of the measuring rod 7, and a pull rod 9 is fixedly installed on the other end of the measuring rod 7. The internal thread of the rotating frame 6 is connected with a screw 10. The portable elevator installation measuring device realizes the precise measurement and adjustment function through the design of the built-in screw rod 3 and the scale rod 4. The rotation of the screw rod 3 is combined with the linear movement of the scale rod 4 to accurately adjust the measurement range and adapt to elevator shaft spaces of different sizes, thereby enhancing the applicability and flexibility of the device. The fixed installation of the rotating head 5 and the design of the rotating frame 6 enable the device to rotate around the axis at a fixed point, which is convenient for users to measure from different angles. The scale rod 4 is slidably connected to the shell 1, the rotating head 5 is rotatably connected to the shell 1, and the sliding connection between the scale rod 4 and the shell 1 and the rotating head 5 The rotating connection between the housing 1 increases the operational flexibility of the measuring device. The user can easily adjust the position of the scale rod 4 as needed to achieve accurate measurement from different angles. The rotatable design of the rotating head 5 makes the entire device more user-friendly and adaptable to complex working environments. The screw 10 is threadedly connected to the measuring rod 7, and the limit block 8 is slidingly connected to the rotating frame 6. The threaded connection between the screw 10 and the measuring rod 7 allows the user to adjust the fixed position of the measuring rod 7 according to actual measurement needs to ensure the accuracy and stability of the measurement. The sliding connection design between the limit block 8 and the rotating frame 6 further improves the adjustability of the measuring rod 7, so that the device can remain stable under different measurement conditions. A handle 2 is fixedly installed on the upper surface of the housing 1, and the surface of the rotating head 5 is provided with anti-slip grooves. The handle 2 design on the housing 1 and the anti-slip texture of the rotating head 5 increase the portability of the device and safety during operation. The addition of the handle 2 makes the device easy to carry and suitable for on-site work, and the anti-slip design of the rotating head 5 ensures stability during operation and prevents measurement errors caused by sliding.

[0023] Example 2

[0024] See also Figure 1-4A torsion spring 11 is fixedly installed inside the rotating frame 6, and a block 12 is fixedly installed on the surface of the outer shell 1. A retaining frame 13 is slidably connected to the surface of the block 12. The inner thread of the retaining frame 13 is connected to a bolt 14. The torsion spring 11 in the rotating frame 6 is designed to be used in combination with the block 12 and retaining frame 13 on the outer shell 1 to achieve the rapid deployment and storage function of the device. The use of the torsion spring 11 provides a way to automatically or semi-automatically open and close the rotating frame 6, greatly improving the convenience during use. The combination of the retaining frame 13 and the bolt 14 ensures the safe locking of the device during use or storage. One end of the torsion spring 11 is fixedly connected to the outer shell 1, the retaining frame 13 is slidably connected to the outer shell 1 and the rotating frame 6, and the bolt 14 is threadedly connected to the block 12. The fixed connection of the torsion spring 11 and the sliding connection design of the retaining frame 13 allow the rotating frame 6 to be automatically deployed or retracted when necessary, and the bolt 14 provides a reliable locking mechanism to ensure the stability and safety of the device during carrying or operation.

[0025] Working principle: First, you need to unlock the bolt 14 located inside the rotating frame 6. This bolt 14 fixes the retaining frame 13 on the block 12 to keep the device in a folded state. After unlocking, the torsion spring 11 causes the rotating frame 6 to automatically unfold. Next, the operator adjusts the screw rod 3 so that the scale rod 4 extends to an appropriate length to accurately measure the width or length of the elevator shaft. At this time, the measuring rod 7 can be flexibly moved in the rotating frame 6 through a sliding connection. Its position can be adjusted and fixed at the threaded connection on the screw rod 3 as needed. Through the turning head 5 on the side of the rotating frame 6, the operator can fine-tune the direction of the device to ensure the accuracy of the measurement. The limit block 8 is installed on the limit rod to prevent the measuring rod 7 from sliding off during the measurement process. After the measurement is completed, the measuring rod 7 can be re-fixed in the rotating frame 6 and tightened with screws 10 to ensure its stability during transportation or storage. Finally, the rotating frame 6 is folded back into the shell 1 and the retaining frame 13 and the block 12 are locked to ensure that the device returns to a compact and safe carrying and storage state.
