Foldable support frame

Abstract

The invention relates to a foldable support frame, which comprises a passage table, a support device and a fixing clamp, wherein the passage table is connected with one side of a tank wall through a rotating shaft, the support device is arranged under the passage table and comprises a triangular supporter, a sleeve, a clamp plate and a support block, the sleeve is welded on the tank wall, the triangular supporter is sheathed in the sleeve, the clamp plate is welded on the triangular supporter, the support block is also welded on the triangular supporter, the fixing clamp consists of a lug plate and a pin, and one end of the fixing clamp is welded on the tank wall. The foldable support frame has the advantages that convenience, high speed, safety and firmness are realized, in addition, the materials are saved, the support frame can be perfectly applied to various fields of structures requiring passage or bay platforms such as slurry fixed control systems and the like, and the moving transportation requirements of drilling crew can be perfectly met.

Description

technical field [0001] The invention relates to a movable support frame, in particular to a retractable support frame. Background technique [0002] Since the aisle platforms produced by our factory have been welded with struts, single and double ear plates and pins for a long time, it is difficult to assemble the pins for the connection of single and double ear plates when supporting the aisle platform; When the table is put down, the pins have to be removed, and the poles have to be manually removed and then put away. When the table is used next time, all the poles and pins must be installed again. The poles are still very expensive and require Machining lug plates is cumbersome and inconvenient. It cannot meet the needs of floating platforms with a large area. It is also very inconvenient for drilling teams who often need to change locations and retract aisle platforms. Contents of the invention [0003] In order to solve the above problems, the present invention provi...
