Description

Technical Field

[0001] This utility model belongs to the field of support technology, specifically, it relates to a movable platform-type temporary support device. Background Technology

[0002] For safety reasons during shaft operations, manual prying is sometimes insufficient, necessitating specialized blasting, which impacts the tunneling progress. When working below chutes or shafts, upper protection is crucial to ensure the safety of personnel and the smooth operation of the work; therefore, support equipment is required.

[0003] Chinese utility model patent CN221074322U discloses a temporary support structure for mining operations. The support protection mechanism involves controlling the retraction of the piston rods of four sets of hydraulic cylinders at the front, then turning on the motor. The motor's rotation drives the lead screw to rotate, which in turn moves the second support platform forward. After the second support platform has moved forward, the hydraulic cylinders are again controlled to extend their piston rods, thus providing stable support for the second support platform. Then, the rear hydraulic cylinders are controlled to repeat the retraction operation. After the hydraulic cylinders have retracted, the motor is controlled to reverse, causing the first support platform to move forward. This achieves the alternating forward movement of the two sets of support platforms.

[0004] Although the structure can provide protective support above, the support area of ​​the device is fixed and cannot be expanded. Furthermore, it cannot provide support in confined spaces. Utility Model Content

[0017] 2. Through the lifting assembly, the extension of the first telescopic cylinder causes the first rotating rod located inside the first sliding rail and the second sliding rail to slide laterally, thereby causing each connecting plate to rotate and the support plate to rise, so that the height of the support plate can be adjusted according to the support position.
