Abstract

A G-shaped hand fastener comprises a hook (1), a fastener body (2) and a supporting member (3). The G-shaped hand fastener is characterized by also comprising a handle (4), wherein the hook (1), the fastener body (2) and the handle (4) are connected in turn; the supporting member (3) is hinged with the fastener body (2); the hook (1), the fastener body (2) and the supporting member (3) radially enclose a climbing object (100) to form a G shape; and a hanging ring (5) is connected to the handle (4) or the fastener body (2). By using the hand fastener, fall prevention protection in the whole procedure of climbing operations can be achieved without changing the structure of the climbing object; the G-shaped opening structure is convenient for passing through rod barriers; the size of the opening can be adjusted in real time during the climbing procedure so as to adapt the thickness change of the climbing object; the structure of the hand fastener is simple, so that a climber can operate the hand fastener by a single hand, master the body balance easily and carry other objects; and the leg fatigue can be reduced by virtue of the upper limb strength, so that the safety and durability of operations are further improved. The hand fastener is suitable for equant and reducing poles, and various circular rods, as well as rectangular section bars and trees, and special shaped climbing objects. The handle fastener is convenient for carrying, is flexible to manipulate and is safe, has low cost, and can be widely used in aerial work fields like electric power, communication, building, fire control etc.

Description

G shape hand button

Technical field the present invention relates to high-altitude operations tool, particularly relates to the fall arrest instrument of climbing.

The safety belt that background technology is generally used at present need tie up on the firm member and just can play protective action, is example with the transmission tower ascend operation, and safety belt is brought into play effect by tying up on the member such as cross-arm.Yet the operating personnel is in the process of climbing shaft tower up and down, and its safety belt performs practically no function because of the body of rod is smooth, and personal safety is threatened.

Though falling proof devices such as Fa Ming rail type, standpipe type, wirerope type have protective action for this reason, need on each electric pole, to set up in advance devices such as guide rail, investment, installation, maintenance are big, are difficult to promote.

ZL 02131022 discloses a kind of falling-prevent climbing pole handle, can connect safety belt in stepping on the bar process; ZL 200820027878 also discloses a kind of pole climbing device, and the scaler can climb and protect by upper limbs force.But the two also has problems in actual applications: 1, adopt circular ring structure difficulty when passing through body of rod barrier; 2, need both hands to handle simultaneously, unbalance easily when the scaler climbs up and down, also be unfavorable for carrying his thing.

Summary of the invention the objective of the invention is to provide a kind of handheld tool of climbing at the defective of prior art or deficiency, need not to change the body construction of climbing thing, is convenient to handle, safely and reliably the scaler is carried out the protection of overall process fall arrest.

Technical solution of the present invention is: operation principle and the features simple structure characteristic of utilizing climbers; design a kind of one-hand control, carry over the climbing hand button of climbing the flexible displacement of thing; this hand button provides to safety belt and can be member and remain connection; when scaler's accidental falling; this hand button is positioned at it securely and climbs on the thing, thereby realizes climbing the protection of operation overall process fall arrest.

Technical characterictic of the present invention is: a kind of G shape hand button, it comprises: crotch (1), button (2), support member (3), it is characterized in that: also comprise a handle (4), wherein, crotch (1), button (2), handle (4) connect successively, support member (3) is hinged with button (2), and crotch (1), button (2), support member (3) radially are the G word shape around climbing thing (100), also connect suspension ring (5) on handle (4) or button (2).

G shape hand button of the present invention can be to wait gauge structure: described crotch (1) is with handle (4) with button (2), button (2) and is fixedly connected.

G shape hand button of the present invention also can be a variable-diameter structure: the distance between described crotch (1) and the support member (3) is adjustable, changes to adapt to the thickness of climbing thing (100).

A) mobile reducing: connecting between described crotch (1) and the button (2) is to move to connect, wherein, the straight section of crotch (1) endwisely slips in the sleeve (201) of button (2), the cross sectional shape of the two slipper is non-circular, in a side of its slip a spring (101) is installed preferably.

B) worm-drive reducing: connecting between described crotch (1) and the button (2) is that tooth connects, wherein, go up additional tooth bar (102) at crotch (1), go up an installation worm screw (202) at the sleeve (201) of button (2), mesh with additional tooth bar (102), worm screw (202) connects with handle (4) by flexible shaft (203), and handle (4) rotates with button (2) and connects.

Described crotch of above structure (1) and support member (3) are arc for the shape of climbing the thing contact-making surface, also can be respectively the various combination of arc, rectangle and given shape.

The invention has the beneficial effects as follows:

1, need not to change climbing thing body construction, can realize climbing the protection of operation overall process fall arrest.

2, adopt the hatch frame of G shape to be convenient to pass through body of rod barrier, can regulate its openings of sizes in real time in the climbing, adapt to the thickness of climbing thing and change.

3, simple in structure, but balance is grasped in scaler's one-hand control easily, also helps carrying his thing, can also alleviate shank fatigue by upper limbs force, further improves security, the durability of operation.
