Description

Technical Field

[0001] This utility model belongs to the field of support equipment technology, and specifically relates to a hydraulic support device. Background Technology

[0002] In tobacco production and processing, it is often necessary to raise tobacco raw materials or production equipment, which requires the use of jacks. Existing jacks are mainly divided into two types: hydraulic jacks and mechanical jacks. However, when these jacks need to lift components located at heights, they require support objects underneath them; furthermore, they are not well-suited for components with tilt angles, meaning they cannot effectively support components of varying heights and tilt angles.

[0003] Therefore, how to design a hydraulic support device that can provide better support for components of different heights and tilt angles has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The support frame is disposed on the top surface of the base, the hydraulic cylinder is vertically disposed on the top surface of the support frame, and the top plate is horizontally disposed on the upper end of the piston rod of the hydraulic cylinder. A pressure relief rod for relieving pressure on one side of the hydraulic cylinder is provided, and a foot pedal for pressurizing the hydraulic cylinder is provided on one side of the support frame. A tension spring is provided between the foot pedal and the base. The support platform is located above the top plate, and the front end of the right side of the support platform is rotatably connected to an upper connecting rod disposed on the front end of the right side of the top plate via a lower connecting rod. An upper support arm is disposed on the left side of the support platform, and a rotating rod is rotatably disposed at the lower end of the upper support arm. A lower support arm is disposed on the left side of the top plate, and a threaded sleeve is vertically disposed in the lower support arm. A lead screw is disposed in the threaded sleeve, and the upper end of the lead screw is rotatably disposed in a blind hole on the rotating rod.

[0007] Preferably, a handwheel is provided at the lower end of the lead screw.

[0008] Preferably, the base is a rectangular structure, and mounting brackets are provided on the bottom surface at each of the four corners of the base, with casters at the bottom of the mounting brackets.

[0011] Preferably, a bearing is provided in the mounting blind hole, and the upper end of the lead screw is interference-fitted with the inner ring of the bearing.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model discloses a hydraulic support device. During use, pressurizing the hydraulic cylinder adjusts the extension length of the piston rod, thereby adjusting the vertical position (height) of the support platform. Rotating the lead screw moves the lower end of the upper support arm up and down, causing the support platform to move accordingly and adjusting its tilt angle. Therefore, this utility model can easily adjust the height and tilt angle of the support platform, enabling it to effectively support components of different heights and tilt angles, thus better meeting the needs of various applications.
