SU14761A1 - Safety buffer for sluice gates - Google Patents

Description

This invention relates to safety buffering devices for locking gates with a blocking chain, fixed in lifting and lowering supports and with the energy absorbed by a moving vessel by lifting loads connected to a barrier circuit. In the proposed device, a special lift-up floor prism is used, which serves to automatically couple the barrier cable with the load intended to absorb the energy of the moving vessel. FIG. 1 is a vertical cross-section of the sluice at the location of the proposed device; and FIG. 2-part buffer device.

The barrier chain K is fixed in supports A and D, placed in grooves and suspended on p-ropes, which are thrown over blocks a and & and screwed onto the drums of the winches W, the Support shown in FIG. 2, represents a hollow prism F with a block J sitting on its shaft d carrying the end of the cable J wound on it (and equipped with a prismatic protrusion L. The latter, after raising the prism to the stop mechanism E, enters the corresponding recess of the drum jT carrying rope m with a load Q

(Fig. 1). The described device is designed so that when the vessel is pressed against the safety chain, the latter is unwound from the block J and causes it to bend the finger t (which is then replaced with a new one), would rotate the drum and thus lift the load Q,

The device can be modified by using a block with a shaft, equipped with a prismatic protrusion at the lower end, and instead of a shaft with a block J, a drum with a corresponding recess on the upper end face.

The subject of the patent.

1. Safety buffer device for sluice gates with a barrage chain fixed in the lifting and lowering supports in which the energy of the moving vessel is absorbed by lifting loads associated with the barrier chain, characterized in that for the automatic coupling of the barrier cable / C (Fig. 1 and 2) with a cargo Q designed to absorb the energy of a moving vessel, a lifting-lowering floor prism F is applied with a block J sitting on a shaft d, carrying the end of the cable D wound on it and equipped with a prismatic protrusion L entering a prism rise to thrust mechanism E in a corresponding recess of the drum T, T carrying rope with load Q.

2, Modification of the device described in p, 1, characterized by its use, replacing the drum P, a block with a shaft fitted with a prismatic protrusion at the lower end, and instead of a shaft with a block /, a drum with a corresponding recess on the upper end face.
