Technical Field

[0001] This utility model relates to the field of elevator inspection technology, and in particular to an elevator shaft pit inspection robot. Background Technology

[0002] In recent years, elevator technology has developed rapidly, and safety inspection has become a top priority. According to TSG T7001-2023 "Rules for Supervision and Periodic Inspection of Elevators", relevant inspection tests need to be filmed. Among them, the car compression buffer test needs to be filmed in the pit, and the buffer should be observed after the car leaves to see if there are any signs of tilting, breakage, plastic deformation, etc.

[0003] During the test, personnel may be bent over and have their bodies compressed. To ensure the safety of the testing personnel, it is proposed to install a portable camera or robot to record the test video inside the pit and upload it to the testing system to ensure the safety, accuracy, and integrity of the test.

[0004] In view of the above reasons, this utility model proposes an elevator shaft pit inspection robot to solve the above technical problems. Utility Model Content

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1-3 As shown, this utility model provides an elevator shaft pit inspection robot, including: a main body 1, which is a rectangular metal box, a walking module 2 installed at the bottom of the main body 1, which can walk in the elevator shaft pit through the walking module 2, a lifting platform 3 that can be raised and lowered relative to the main body 1, a pitching mechanism 4 installed on the lifting platform 3, and a camera module 5 installed at the top of the pitching mechanism 4. The inspection robot can be moved to the corresponding position through the walking module 2, and then the lifting platform 3 is raised to the corresponding height. The camera module 5 is adjusted to the corresponding angle under the action of the pitching mechanism 4, so as to observe whether the buffer has tilted, broken, plastic deformation or other phenomena after the car leaves.

[0029] Specifically, a track 6 is installed in the elevator shaft pit, and the walking module 2 can move along the track 6 in the elevator shaft pit. In this embodiment, the track 6 is suspended in the elevator shaft pit and includes an outer ring track 601 and cross tracks 602 connected to the middle of each side. The track 6 is a double track, and the cross sections of the outer ring track 601 and the cross tracks 602 are both double U-shaped. The intersection of the cross tracks 602 is hollowed out to avoid interference with the buffer 7 set in the middle of the elevator shaft pit. The walking module 2 includes four rollers arranged in front and behind. The rear rollers are driven by a hub motor, thereby moving the inspection robot along the track 6 and adjusting its position in the elevator shaft pit.

[0030] In this embodiment, the four bottom corners of the lifting platform 3 are connected to the main body 1 through the first electric push rod mechanism 8. The four sets of first electric push rod mechanisms 8 control the lifting and lowering synchronously, so that the lifting platform 3 can rise and fall smoothly.

[0031] In this embodiment, the bottom of the main body 1 is provided with an openable door. Inside the main body 1 is a mobile power supply that powers the motors of the four sets of first electric push rod mechanisms 8, and the mobile power supply can also provide power to the hub motors. The bottom of the main body 1 is also provided with a controller, which can control the speed of the hub motors, the movement of the first electric push rod mechanisms 8 and the pitch mechanism 4, etc.

[0032] In this embodiment, a remote controller 9 is also included. The remote controller 9 and the controller can communicate wirelessly via Bluetooth or a 5G module, thereby enabling the operator to control the movement of the inspection robot, the lifting platform 3, and the pitch mechanism 4 from outside the elevator shaft pit.

[0033] Specifically, the remote controller 9 is equipped with a power switch 901, a travel control button 902, a lifting button 903, and a pitch button 904 for controlling the pitch angle of the pitch mechanism 4. Additionally, the remote controller 9 is embedded with a display screen 905, which displays the images captured by the camera module 5 in real time. This allows operators to adjust their operations based on the images, ensuring that the camera module 5 can capture a clear overall image of the buffer 7 and observe for any tilting, breakage, or plastic deformation.

[0034] In this embodiment, the pitch mechanism 4 includes two support plates 401 arranged vertically on the surface of the lifting platform 3. The middle part of the rotating rod 402 is rotatably connected to the support plates 401 through a rotating shaft 403. The camera module 5 is mounted on a fixed plate 404 at one end of the rotating rod 402. The other end of the rotating rod 402 is hinged to the movable end of the second electric push rod mechanism 10 arranged on the surface of the lifting platform 3.

[0035] In this embodiment, the camera module 5 is a high-definition camera. To ensure its operation in the dimly lit elevator shaft pit, light strips 11 are installed on both sides of the camera module 5 on the mounting plate 404. The light strips 11 can provide auxiliary lighting when shooting in the pit, avoiding the defect that the buffer 7 cannot be observed due to dim lighting.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
