High fence supports can be expensive, difficult to ship, and awkward to install. Often, and particularly for the control of deer, it is desirable to increase the height of existing fence that uses steel T-posts for support. The T-post extender combined with a steel T-post becomes a high fence support useful for supporting high fence. A T-post extender consists of a longitudinal element, typically a length of steel rebar, and a stop element, typically a washer welded to the longitudinal element at a selected location along its length. For existing T-post fence supports, the T-post extender is slipped into place alongside the top of the T-post where it is captured laterally by existing wire ties and vertically by the stop element resting against the top of the T-post under the force of gravity. This arrangement has cost, installation, and shipping advantages both in new high fence construction and in the case where the height of existing T-post supported fence must be increased.

A support installation for a fairground attraction, comprises a base, two pairs of masts which can be moved between a collapsed and an erected position, as well as a head that in the erected position is at the top of the masts, on which head a Ferris wheel or a swing or the like can be mounted, wherein the masts each comprise several segments that are joined to one another such that they can pivot. Each mast has a base segment that is joined to the base such that it can pivot, as well as a top segment that is joined to the head, at least in the erected position. Relatively high masts can be obtained with this construction.

The invention relates to an aggregate working face along-slot advanced reinforced support method and its special hydraulic support. The inventive method comprises: (1) a series of head hydraulic supports are mounted on the end of rail; several series of advanced reinforced hydraulic supports are laid in sequence along the propulsion direction, wherein, the first series laid in the same direction with the head supports while the left laid normally; (3) each hydraulic supports is moved along the guide rail in the bottom slide track of base box by the traction device; all the guide rails of hydraulic support connect end-to-end as a whole to make the support move straight; (3) when moving the support, the next series of hydraulic support offer cantilever beam for support in time to avoid top empty; (4) the lateral distances between posts of each series are increased as the channel for passengers and carrying material; (5) the said guard plates on the two sides of top beam support the top plate of two sides. Said invention need propulsion device, guide rail, cantilever beam, and side guard plate. It uses self-moving advanced reinforced support to reduce workload and labor strength, increase working efficiency, guard effect and safety.

The invention discloses a shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device used for coal mining. The shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device comprises a base, a supporting plate, a rotary shaft and a connecting rod, wherein two slide paths are symmetrically mounted on the upper surface of the base; two slide slots are symmetrically formed in the two sides of each slide path; movable blocks are movably mounted in the slide slots; opposite sides of the two movable blocks are connected with the two ends of the rotary shaft; a sleeve column is fixedly arranged on the upper surface of the base; an inner column is spliced in the sleeve column; the upper surface of the sleeve column is connected with thelower surface of the supporting plate through a spring; a fixed block is fixedly arranged on the lower surface of the supporting plate; a rotary slot is formed in the fixed block; the rotary shaft ismounted in the rotary slot; and the two ends of the connecting rod are separately connected with the fixed block and the rotary shaft on the movable blocks. The shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device has the advantages of regulating supporting height of integral equipment according to earth surface sinking degree, keeping a pipeline in the horizontal state, and preventing the pipeline from sinking and cracking.
