Description

A portable height-adjustable support device

Technical Field

The utility model belongs to the technical field of supporting devices, and in particular relates to a portable supporting device with adjustable height.

Background Art

When dismantling the switch angle steel or replacing the rails, the switch or rod will sink due to lack of support, which may easily cause damage to the switch or rod. In the past, when dismantling the switch angle steel or replacing the rails, wooden blocks were usually used as pads to support the switch or rod to prevent the switch or rod from sinking and being damaged due to lack of support. However, there are obvious disadvantages in using wooden blocks. First, the specifications of wooden blocks are usually fixed and cannot be adjusted up and down. When the height does not meet the usual specifications, wooden blocks of different specifications need to be used for support. Second, wooden blocks are usually large in size, which is extremely inconvenient to carry and transport, with low maintenance efficiency and high labor costs. Third, as a wooden material, wooden blocks are prone to dents or even damage when under great pressure, which easily increases replacement costs. At present, there is a lack of a portable and height-adjustable support device to provide stable bottom support for the disassembly and assembly of switch machines or rods.

Therefore, a new technology is needed to solve the problem of lack of a portable height-adjustable support device in the prior art.
