Abstract

PURPOSE:To cause a gate to fall down under its own weight by turning off a clutch in case of emergency by a method in which a threaded shaft to support the gate is screwed with a rotary part and an electromagnetic clutch is provided between the upper end of the threaded shaft and the unturnably supporting part. CONSTITUTION:A gate bar 6 at the upper part of a gate 5 is connected with a threaded shaft 7 with a coupler 8 having a thrust bearing 9, and the threaded shaft 7 is screwed with a rotary part 17 through a ball. In this case, the upper end of the threaded shaft 7 is so designed that a state that a vertically movable supporting part 13 is integrally connected with a guide 15 by an electromagnetic clutch 13 and a state that they are in relatively rotatable state can be switched to each other. To vertically move the gate 5 in usual case, the clutch 16 is turned ON and a motor 21 is operated while regulating the rotation of the threaded shaft 7, whereupon the rotary part 17 turns through gear mechanisms 18 and 19 and the threaded shaft 17 moves vertically. In case of emergency, the clutch 16 is turned OFF, whereupon the threaded shaft goes down while turning under the weight of the gate to shut out the opening 2a rapidly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a spiral shaft that suspends and supports a gate with a vertical squid in an upward N-position and a downward closed IIk position, which is non-rotatable and is held in an up-and-down one-way rudder. - provided with a rotary post, which is screwed onto the IK-, is supported in a manner that it cannot move up and down, and is provided with a nine-shape structure;

No. 418 Publication Iso), the clutch LA1 for switching between the state of blocking the peak of the gate, the state of #V-valley, and the state of tc is connected to the 1J11 rotating shaft for dart operation and the rotating positioning of it. Kmll! In the darkness with the connecting gear interlocking machine #1c141, 1 is interposed with a state that switches between a down type that connects them together and a state that allows their relative rotation, 4. The gate's own weight is lowered by rotating the Ig1 rotation m which is screwed into the gate suspension support screw shaft a and the umbrella gear interlocking mechanism together with the rotating parts as the fly moves downward. Well, there was the inconvenience of not being able to use the 11th gate. Rimashi, # marked rotating material-1 and gear interlocking-4Q4 can be rolled down by 1g1, which is the enemy of the large operating force, @grave gate's dead weight fist, place- It was a cruel thing to gain the power of control.

The purpose of the main guard is to make it possible to properly lower the 4i gate under its own weight.

The structure of the wooden tank is to rotatably connect the screw shaft that supports the hanging gate to the dart, and to switch the structure between the lower type that prevents the dart from falling under its own weight, and the lowered type that allows it. A round clutch is interposed between the screw shaft and the lumber that supports it non-rotatably in a manner that allows the two to be integrally connected and another that allows their relative rotation. Dead weight lowering cargo! The operating force used to rotate the screw shaft is applied to the front rotation member and the gate operation. FfIlj

K also makes it difficult to rotate the screw shaft, so K was designed so that even lightweight gates could be lowered by their own weight appropriately.

Next, the embodiments of the present invention will be described based on the drawings. I will clarify.

A cam follower bearing U connected to the Qll is formed into a cast mark-like copper (to), and a friend guide (119) is provided with a vertical movement 11Ka & a, and a screw shaft support @ (to) is provided.
and the upper end of the screw shaft (1), there is a dart (a shape that connects them integrally and a shape that allows relative rotation between them, in order to switch between a shape that prevents the descent of the dead weight of Il and a down shape that allows it). It is installed in a folded state with an electromagnetically operated multi-plate shoe clip (toward) inserted into the storage compartment. The rotating shaft (111) for gate operation is provided with a rotating shaft (111) that does not move up and down.
The output gear (18 m) of the rotary shaft is integrated with the rotary shaft 11η to rotate it, and a nine-man key gear (IV

An electric carpet arresting machine (2) equipped with a gate operating shaft (to) is interlocked and connected to the rotary shaft (to) k for controlling the gate so that it can be operated in the forward and reverse directions. 1 opening (2 openings can be closed, and 1 ml can be held in the open shape, and 1 clutch can be changed to D cut-off type 09J) (Goo) This comprises a self-weight dropping brazing gate device that can emergency close the opening (21).

Next, to describe an example of the convenient use of the above-mentioned gate d device, the above-mentioned clutch (to) disengagement operation #@ electric switch is provided in a completely convenient manner so that it can be operated at the front so that it can be shut off in an emergency. Often, the electric switch for cutting operation of the latch (to) marked -θ is connected to a device for detecting whether the fluid prepressure at mRtlkK downstream of the gate (5) is below the set value. The automatic hook may be overloaded to prevent the automatic hook from operating when a state in which the value is higher than the set value is detected, thereby improving safety.
