Description

Technical Field

[0001] This utility model relates to the field of fire-fighting tools technology, and in particular to a portable electric hydraulic demolition tool. Background Technology

[0002] With the maturity of hydraulic technology and lithium battery power systems, electric hydraulic rescue tools have developed rapidly. Their core principle is to convert hydraulic energy into mechanical energy through an electric pump, which drives the tool head to achieve cutting, expansion, and jacking functions. Compared with traditional gasoline manual hydraulic tools, electric hydraulic rescue tools have the advantages of being quiet and environmentally friendly, portable and flexible, and requiring no external power source. They are especially suitable for rescue in confined spaces. In recent years, the application of modular quick-change systems and intelligent control technology has further improved their emergency response efficiency and operational accuracy.

[0003] When using hydraulic rescue tools for emergency rescue, traditional hydraulic rescue tools require an external power source and are bulky, making it difficult for rescuers to deploy them quickly in complex environments, thus delaying the golden rescue time. In addition, different search and rescue operations require different tools. Existing electric hydraulic rescue tools are fast, but they also have certain limitations, such as limited heat dissipation capacity, making them unsuitable for long-term high-load operations, and requiring long-term maintenance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable electro-hydraulic demolition tool, which aims to improve the problem of cumbersome tool replacement in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable electric hydraulic demolition tool, comprising a housing, a hydraulic pump fixedly connected to the inner wall of the housing, a second column fixedly connected to the right outer wall of the hydraulic pump, a perforated column slidably connected to the inner wall of the second column, a ball groove formed on the inner wall of the perforated column, a ball retainer slidably connected to the inner wall of the ball groove, an air outlet and an air inlet formed on the rear side of the second column, an air outlet pipe connected to the rear side of the air outlet, an air inlet pipe connected to the rear side of the air inlet, a cylinder connected to the left side of the air inlet pipe, a limit plate slidably connected to the inner wall of the second column, a first column slidably connected to the outer wall of the hydraulic pump, a slotted second column slidably connected to the inner wall of the first column, a limit groove formed on the inner wall of the slotted second column, and a power supply mechanism fixedly connected to the outer wall of the housing, the power supply mechanism being used to increase the additional endurance function of the equipment.

[0007] As a further description of the above technical solution: A handle is slidably connected to the outer wall of column one, and a gripper is fixedly connected to the top of the handle.

[0008] As a further description of the above technical solution: The inner wall of the gripper is slidably connected to a limiting post, and the outer wall of the limiting post is rotatably connected to a linkage rod.

[0009] As a further description of the above technical solution: The rear side of the linkage rod is rotatably connected to a linkage block, and the inner wall of the linkage block is threadedly connected to a limit post two.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the air cylinder is used as the air outlet to draw out the interior of the second column. After the air pressure decreases, the limiting plate is lifted. Then, the slotted column two, which is slidably connected to the hydraulic pump, is adsorbed onto the inner wall of the second column. The ball in the perforated column will also be naturally stuck between the limiting groove and the ball groove under the action of pressure. Gas is injected from the air outlet, and the ball will be pressed back to the top of the second column by the air pressure. At this time, the first column and the slotted column two can be removed to replace different types of tools.

[0014] 2. In this utility model, when the device has insufficient power, the protective shell is opened, and the lowest part of the slotted column can be slid through the slotted column. Due to the movement of the fixed platform, the connecting rod support will be opened, and the fixed column inside the connecting rod will be connected to the solar panel. The solar panel will also be fully unfolded under the rotation of the rotating shaft. Attached Figure Description
