Abstract
The utility model relates to a double-groove type falling protector and solves the problem that an existing falling protector is single in structure. The falling protector comprises a base and a connecting lever hinged to the base. A main through groove and an auxiliary through groove allowing anti-falling rails to penetrate are formed in the base. The middle of the connecting lever is hinged to the base through a connecting pin. The head of the connecting lever extends into the main through groove. The head of the connecting lever is of a cam shape or a eccentric wheel shape. The tail of the connecting lever is provided with a safety belt hole. A torsion spring is disposed between the connecting lever and the base through the connecting pin. The torsion spring can allow the head of the connecting lever to keep contacting with the anti-falling rail in the main through groove. The torsion spring is mounted on the connecting pin. The double-groove type falling protector is simple in structure, novel in design and reasonable in structure by the double-groove design, the double-groove type falling protector can slide on a transverse rail easily and smoothly, operations of overhead operators are unaffected by the falling protector, the operators can operate securely, and safety of the operators is guaranteed.
Description
Technical field
The utility model relates to falling-proof safety device technical field, is applicable to high-altitude and the overhead operation of the systems such as electric power, chemical industry, building, specifically a kind of.
Background technology
In the systems such as electric power, chemical industry, building, often have work high above the ground, in order to ensure operating personnel's life security, must have falling proof device reliably.Falling proof device be for work high above the ground personnel climbing, prevent from falling when the situation such as high-altitude moves, work high above the ground and starve a kind of security system, increased the guarantee of safety together to operating personnel.And catching device is most important parts in falling proof device, existing catching device structurally only has a conduit, in this conduit, be also provided with brake apparatus, the effect of brake apparatus is mainly reflected in the braking on long rails, in the time that catching device slides on cross track, the braking action of brake apparatus is not only useless, but also can affect the slip of catching device on cross track, can impact work high above the ground personnel's operation, thereby even make it divert one's attention to cause the generation of falling accident.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of dual grooved catching device of new structure is provided.
The utility model is achieved by the following technical solution:
A kind of dual grooved catching device, comprise pedestal and be hinged on the connecting lever on pedestal, (bottom surface of pedestal offers the bayonet socket communicating with main groove on pedestal, to offer the main groove that passes for anti-fall track and secondary groove, the side surface of pedestal offers the bayonet socket communicating with secondary groove, and bayonet socket is for the anti-fall track of clamping); The middle part of connecting lever is hinged on pedestal by attachment pegs and the head of connecting lever extend in the main groove of pedestal, and the head of connecting lever is cam-shaped or eccentric wheel shape, and it is with holes that the afterbody of connecting lever is provided with safety; The torsionspring that is provided with the anti-fall track that can make in connecting lever head and main groove and is kept in touch state between connecting lever and pedestal by attachment pegs, torsionspring is arranged in attachment pegs.Wherein, the main groove on catching device pedestal is for long rails, and the secondary groove on pedestal is for cross track.
When concrete use, in with holes the safety that safety belt one end ties up on operating personnel's health, the other end ties up to catching device, in the time that operating personnel is upwards climbed by column foot, in the main groove that penetrates into bottom catching device of long rails, catching device is upwards operation under operating personnel's drive, and the main groove of catching device moves on long rails, under the effect of operating personnel's pulling force, the connecting lever head of catching device leaves long rails, catching device just can slide easily on long rails like this, when operating personnel falls, the connecting lever head of catching device fixes and on long rails, realizes locking rapidly under the acting in conjunction of operating personnel's gravity and torsionspring, plays locking protection, in the time that will arriving on cross-arm, operating personnel wants horizontal shift, now catching device is slid into switching tracks on way block of rail replacer, rotate the way block that switches tracks and become horizontal direction, make the secondary groove of catching device aim at cross track, then operating personnel pulls catching device, the secondary groove of catching device has just penetrated on cross track, catching device is both direction free-running operation to the left or to the right under operating personnel's drive, because there is no connecting lever in the secondary groove of catching device, so catching device can easily slide on cross track, in the time that operating personnel falls, catching device can be stuck on cross track inflexibly, prevent falling of operating personnel.Operating personnel is returned in surface process by tower top, and catching device relies on the gravity of self to move downwards, and while falling, the connecting lever of catching device is because power direction changes, and connecting lever moment is tightly locked on long rails, stops the generation of fall event.
Further, the tip position that is positioned at main groove two ends notch on pedestal is separately installed with the roller that can roll on anti-fall track.Frictional force when roller is set on catching device has reduced that catching device slides in orbit, makes its slip easier.
The utility model apparatus structure is simple, novel in design, the design in double flute road makes its structure more reasonable, when this device is slided on cross track more easily, more unblocked, can not impact work high above the ground personnel's operation, can make its operation more securely, thereby ensure operating personnel's security.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model device.
In figure: 1-pedestal, 2-connecting lever, the main groove of 3-, the secondary groove of 4-, 5-attachment pegs, with holes, the 7-roller of 6-safety.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of dual grooved catching device, comprises pedestal 1 and is hinged on the connecting lever 2 on pedestal 1, offers the main groove 3 and the secondary groove 4 that pass for anti-fall track on pedestal 1; The middle part of connecting lever 2 is hinged on pedestal 1 by attachment pegs 5 and the head of connecting lever 2 extend in the main groove 3 of pedestal 1, and the head of connecting lever 2 is cam-shaped or eccentric wheel shape, and the afterbody of connecting lever 2 is provided with safety with holes 6; The torsionspring that is provided with the anti-fall track that can make in connecting lever 2 heads and main groove 3 and is kept in touch state between connecting lever 2 and pedestal 1 by attachment pegs 5, torsionspring is arranged in attachment pegs 5.
When concrete enforcement, the tip position that is positioned at main groove 3 two ends notches on pedestal 1 is separately installed with the roller 7 that can roll on anti-fall track.
