Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance tooling technology, and in particular to a multifunctional portable tooling for elevator maintenance. Background Technology

[0002] The continuous acceleration of urbanization and the emergence of high-rise buildings have made elevators an indispensable vertical transportation tool in modern life. The number of elevators in my country has been increasing year by year, reaching millions to date, and is still increasing by a considerable number every year. The large number of elevators means a huge amount of maintenance work. As special equipment, the safe and stable operation of elevators is related to the lives of passengers. Regular, professional and efficient maintenance is an essential link. The slightest negligence may cause malfunctions, resulting in people being trapped or even causing serious safety accidents. Modern elevators integrate multiple technologies such as mechanical, electrical, electronic and intelligent control, and their structure is becoming increasingly complex. From the traction system, guiding system, car system, to the door system, electrical control system and safety protection system, each part cooperates with each other and is independent of each other. The causes of failure are extremely diverse.

[0003] A search revealed Chinese Patent Publication No. CN209276075U, which discloses a multifunctional portable elevator fixture, including a supporting base plate. Casters are installed at the four corners of the bottom of the supporting base plate. Uprights are fixedly installed on both sides of the top of the supporting base plate. A lifting platform is slidably installed between the two uprights along the vertical direction. Fixed pulleys are rotatably installed at the top of each of the two uprights. Lifting grooves are provided on the sides of the two uprights that are far apart from each other. A lead screw motor is fixedly installed on the bottom inner wall of the lifting groove. A lead screw is fixedly installed on the output shaft of the lead screw motor via a coupling. This utility model represents one aspect of the invention. This multi-functional portable elevator tool boasts a simple overall structure and convenient operation, facilitating lifting, installation, and maintenance within elevators. Its casters enhance portability, making it easy to move and carry, thus meeting user needs. However, this elevator maintenance tool is largely limited in function. When performing complex maintenance tasks, frequent tool switching becomes the norm. For example, checking the elevator control system circuitry requires first using a multimeter to measure voltage and current to identify any abnormalities, then switching to a screwdriver to disconnect the terminals and inspect the wiring connections. If insulation issues are suspected, a megohmmeter is also needed. This constant tool switching is not only cumbersome but also prone to omissions or incorrect tool selection, further complicating the already complex maintenance process and hindering quick and efficient work completion. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-functional portable tool for elevator maintenance, which aims to improve the problem that most traditional elevator maintenance tools in the prior art have only one function.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-functional portable tool for elevator maintenance, comprising a main frame, a motor fixedly connected to the rear side of the main frame, a bevel gear one fixedly connected to the output end of the motor, a bevel gear two meshing with the outer wall of the bevel gear one, a threaded shaft fixedly connected to the top of the bevel gear two, a connecting plate threadedly connected to the outer wall of the threaded shaft, a fixing plate fixedly connected to the front side of the outer wall of the connecting plate, telescopic rods fixedly connected to the left and right ends of the front side of the outer wall of the fixing plate, and a fixing mechanism provided on the front side of each of the two telescopic rods for fixing.

[0010] As a further description of the above technical solution:

[0011] A controller is fixedly connected to the top left side of the main frame, and the controller is electrically connected to the motor.

[0012] Through the above technical solution, a fixedly connected controller is designed and installed at the top left of the main frame. This controller is carefully positioned within the main frame, and its main function is to control the operation of the entire system. Through an electrical connection with the motor, it achieves precise control of the motor. This electrical connection ensures that the controller can send commands to the motor in real time, thereby enabling efficient motor management.

[0013] As a further description of the above technical solution:

[0014] Protective plates are fixedly connected to the left and right sides of the outer wall of the main frame, and protective strips are fixedly connected to the front and rear sides of the outer wall of the main frame.

[0015] Through the above technical solution: protective plates are fixedly connected to both sides of the outer wall of the main frame. The function of these protective plates is to prevent external impacts or collisions from damaging the main frame during use. They are tightly attached to the left and right sides of the outer wall of the main frame.

[0016] As a further description of the above technical solution:

[0017] A toolbox is fixedly connected to the top right side of the main frame, and a handle is fixedly connected to the top of the toolbox.

[0018] Through the above technical solution: on the top right side of the main frame, we can see that a toolbox is firmly connected to it. This toolbox is not only fixed in the designated position of the main frame, but also has a handle on its top for easy gripping. This handle not only makes it easy for users to lift or move the toolbox when needed, but also ensures the stability and safety of the toolbox during use.

[0019] As a further description of the above technical solution:

[0020] A mounting plate is fixedly connected to the bottom of the main frame, and wheels are fixedly connected to the four corners of the bottom of the mounting plate.

[0021] Through the above technical solution: the bottom of the main frame is connected to the mounting plate by a fixed connection. Specifically, the mounting plate is designed to be tightly integrated with the bottom of the main frame to ensure that there is no relative movement between the two. In order to further enhance the stability of the structure and facilitate movement, wheels are fixedly connected to the four corners of the bottom of the mounting plate.

[0027] Through the above technical solution, an anti-slip sleeve is also securely fixed to the upper part of the outer wall of the push rod using a similar fixing method. There may be repetition here, as the anti-slip sleeve is described as being self-fixed.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the device is working, it is controlled by a controller fixed at the top of the main frame, so that the motor can drive the first bevel gear fixedly connected to its output end to rotate. The second bevel gear meshing with the outer wall of the first bevel gear can drive the threaded shaft fixedly connected inside to rotate, thereby controlling the movement of the connecting plate threaded on the outer wall of the threaded shaft. It can be adjusted for extension and retraction during maintenance, thereby improving its flexibility and adaptability, and greatly improving the work efficiency of maintenance personnel.

[0030] 2. In this utility model, in order to better replace the tool, a fixed shaft is fixedly connected to the outer wall of the telescopic rod, and a sliding groove is opened on the outer wall of the fixed shaft. A sliding sleeve is slidably connected to the outer wall of the sliding groove. When the bottom of the sliding shaft fixed at the upper and lower ends of the outer wall of the tool interface slides and the locking block is locked onto the outer wall of the sliding groove opened on the fixed shaft, the tool interface is pushed by an external force and thus slides out from the inclined side of the sliding sleeve, thereby achieving the effect of quickly changing the workpiece.
