Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-3, in an area requiring high-altitude operation, in order to protect safety of workers, a fence is disposed at an edge of the operation area, and the workers can avoid falling from high altitude by binding safety ropes to the fence. Meanwhile, in order to facilitate the walking of workers in a working area, the rail is generally provided with a guide rail N, the workers are connected with the anti-falling device through one end of the safety rope and are in sliding connection with the guide rail N, so that the anti-falling device can slide on a slide way of the guide rail N, and the workers can walk in the working area while binding the safety rope. Moreover, since some work requires working outside the work area over the fence, the guide rail N on the fence is usually made of two mirror-image pieces, so that the fall arrestor can slide on the guide rail both inside and outside the fence.
The invention provides a guide rail steering gear 10 which is used for being matched with a guide rail N, so that when a worker works aloft and needs to cross a fence, the worker can directly convert the position of a falling protector on the guide rail N through the guide rail steering gear 10 without loosening the falling protector. The guide rail redirector 10 comprises a rotating device 20 and a connecting seat 30, wherein the connecting seat 30 is disposed between two sections of guide rails N, and the rotating device 20 is rotatably connected with the connecting seat 30 and can rotate relative to the connecting seat 30. When high-altitude operation is needed, the anti-falling device is clamped on one side of the guide rail N and slides on one side of the guide rail N to walk in a working area. When the operation needs to be carried out outside the working area, namely the anti-falling device needs to slide on the other side of the guide rail N, the anti-falling device slides to the rotating device 20, the rotating device 20 rotates relative to the connecting seat 30, so that the anti-falling device rotates to the other side of the guide rail N along with the rotating device 20, and the rotation of the anti-falling device on the guide rail N is realized.
It should be noted that the anti-falling device is a buckle which is clamped on the guide rail in a sliding manner and is connected with a worker through a safety rope, so that the worker and the guide rail N are connected through the safety rope to prevent falling.
The working area refers to a range surrounded by a fence during high-altitude operation, and the tower is a working area during operation on a high tower.
Specifically, a section of interval H is reserved at a fixed distance from the guide rail N on the fence, and the connecting seat 30 is fixedly connected to the interval H of the guide rail N on the fence. The rotating device 20 includes a rotating block 201 and a limiting plate 203, the rotating block 201 is rotatably connected to the connecting base 30, and can rotate relative to the connecting base 30, that is, relative to the guide rail N, so that the rotating block 201 rotates to a position where it is spliced with the guide rail N. After the rotating block 201 rotates to the joint with the guide rail N, the fall protector can slide onto the rotating block 201 from the guide rail N, and can also slide onto the guide rail N from the rotating block 201. Limiting plate 203 is connected with commentaries on classics piece 201, and can follow commentaries on classics piece 201 and together rotate relative connecting seat 30, when changeing piece 201 and rotating the position with guide rail N concatenation, limiting plate 203 fixes a position commentaries on classics piece 201.
It can be understood that the rotating block 201 can be respectively spliced on both sides of the guide rail N by rotating relative to the connecting seat 30, so that when the fall arrester slides on the rotating block 201, the falling arrester slides from one side of the guide rail N to the other side along with the rotation of the rotating block 201.
It should be noted that, one side and the other side of the guide rail N respectively guide one side of the guide rail close to the working area and one side of the guide rail far from the working area.
It should be noted that the joint between the rotating block 201 and the guide rail N is the position where the rotating block 201 is parallel to the guide rail N, and the fall arrester can slide onto the rotating block 201 through the guide rail N, or slide onto the guide rail N from the rotating block 201.
Referring to fig. 4-6, when the rotating block 201 rotates to a position where it is spliced with one side of the guide rail N, there is a gap L between the rotating block 201 and the guide rail N due to a machining error or a margin for preventing the rotating block 201 from interfering with the guide rail N. When the anti-falling device slides from the rotating block 201 to the guide rail N or slides from the guide rail N to the rotating block 201, the anti-falling device passes through the gap L, so that the anti-falling device can be blocked or deadly blocked by the gap L when sliding to the gap L, and potential safety hazards are caused.
Therefore, the rotating block 201 is configured to be telescopic along the direction that the fall arrester slides on the guide rail, that is, when the rotating block 201 rotates to the position of being spliced with the guide rail N, two opposite sides of the rotating block 201 can also extend towards the direction close to the guide rail N respectively. Therefore, when the rotating block 201 rotates to a position spliced with the guide rail N, the gap L between the rotating block 201 and the guide rail N is filled up through the extension of the rotating block 201, so that when the anti-falling device slides onto the rotating block 201 from the guide rail N or slides onto the guide rail N from the rotating block 201, the anti-falling device cannot be blocked or deadly due to the gap between the rotating block 201 and the guide rail N, and the anti-falling device needs to be loosened, thereby causing potential safety hazards.
Specifically, the rotating block 201 includes a telescopic portion 2011, the telescopic portion 2011 is a multi-section structure, and the multiple sections are connected to each other, so that when the telescopic portion 2011 is stretched or compressed, the multi-section structure of the telescopic portion 2011 can be stretched or overlapped to achieve the telescopic effect. That is, when a tensile force is applied to the extendable part 2011 in both directions, the extendable part 2011 extends in multiple stages so that the extendable part 2011 extends in both directions. When the multi-extensible part 2011 applies a compressive force from both sides to the middle, the multiple sections of the extensible part 2011 are stacked so that the extensible part 2011 contracts toward the middle.
When the rotary block 201 is rotated to a position where it is engaged with the guide rail N, the extending portion 2011 extends in a direction approaching the guide rail N to fill the gap L. When the rotating block 201 needs to rotate to the other side of the guide rail N, the telescopic part 2011 contracts, so that a gap L exists between the rotating block 201 and the guide rail N, and interference between the rotating block 201 and the guide rail N during rotation is avoided.
In some embodiments, the extending/contracting part 2011 may have an elastic structure, and extend/contract by elasticity to fill the gap L.
Note that the expansion and contraction of the expansion and contraction portion 2011 may be performed by providing a cylinder inside the expansion and contraction portion 2011 and pushing the expansion and contraction portion to expand or overlap with the cylinder by a push rod of the cylinder. Alternatively, the outermost layer of the multi-section structure of the extending/contracting portion 2011 may be an electromagnet, and the magnetic attraction guide rail N is generated after the electromagnet is powered on to extend. The telescopic part 2011 can also be stretched or compressed directly by manual work, that is, when the rotating block 201 rotates to the position spliced with the guide rail N, the telescopic part 2011 is stretched or compressed manually.
It can be understood that the rotating block 201 is adapted to the size of the guide rail N, that is, when the rotating block is at the position of being spliced with the guide rail N, the fall arrester can slide smoothly on the rotating block 201 and the guide rail N.
Furthermore, a through hole 2013 and a sliding groove 2015 are formed in the rotating block 201, and the sliding groove 2015 is arranged on the surfaces of the two opposite sides of the rotating block 201. The through hole 2013 penetrates through the rotating block 201 along the direction of the sliding groove 2015 and is matched with the shaft hole of the connecting base 30 to realize the rotating connection between the rotating device 20 and the connecting base 30. The fall arrester slides in the chute 2015 when sliding from the guide rail N onto the rotating block 201.
It can be understood that when the rotating block 201 rotates to splice with the guide rail N, the chute 2015 is communicated with the slideway on the guide rail N, so that the fall arrester can continuously slide.
Referring to fig. 5 again, the number of the limiting plates 203 is two, and the two limiting plates 203 are respectively disposed on two sides of the rotating block 201 close to the guide rail N, and are located between the rotating block 201 and the guide rail N, and rotate together with the rotating block 201. When the rotating block 201 rotates to the joint with the guide rail N, the rotating block 201 is positioned.
Specifically, the limiting plate 203 is provided with a limiting boss 2031 and a notch 2033, and the limiting boss 2031 is a boss protruding out of the surface of the limiting plate 203. When the rotating block 201 rotates to the position where the rotating block is spliced with the guide rail N, the limiting boss 2031 contacts the connecting seat 30 to limit the rotating block 201 to continue rotating, so that the rotating block 201 is positioned. When the rotating block 201 rotates to the joint with the guide rail N, the position of the notch 2033 corresponds to the slide way of the guide rail N, and the fall protector can pass through the notch 2033 when sliding on the rotating block 201 to the guide rail N or sliding on the rotating block 201 from the guide rail N, so that the limiting plate 203 cannot block the sliding path of the fall protector on the rotating block 201.
It will be appreciated that the size of the gap 2033 is larger than the size of the fall arrestor so that the fall arrestor can pass through the gap 2033.
Further, the limiting boss 2031 is disposed on a surface of the limiting plate 203 away from the rotating block 201.
Referring to fig. 7, the connecting seat 30 includes a base connecting portion 301 and a sidewall connecting portion 303, the sidewall connecting portion 303 is disposed at two opposite sides of the base connecting portion 301, the base connecting portion 301 is fixedly connected to the space H between the guide rails N, and the sidewall connecting portion 303 is rotatably connected to the rotating block 201.
Specifically, the connecting seat 30 further includes a rotating shaft 305, a connecting hole 3011 is formed in the base connecting portion 301, and the base connecting portion 301 is fixed at the interval H between the guide rails N by passing a screw through the connecting hole 3011. The side wall connecting portion 303 is provided with a rotating hole 3031, the through hole 2013 of the rotating block 201 is concentric with the rotating hole 3031, the rotating shaft 305 penetrates through the through hole 2013 and the rotating hole 3031, and the rotating shaft 305 is in interference fit with the through hole 2013 and is in clearance fit with the rotating hole 3031, so that the rotating block 201 is rotatably connected with the connecting seat 30.
Further, the connecting base 30 further includes a motor (not shown), and an output shaft of the motor is connected to the rotating shaft 305 to drive the rotating shaft 305 to rotate, so as to drive the rotating block 201 to rotate.
It should be noted that, in some embodiments, the connection holes 3011 may be omitted, and the base connection portion 301 may be fixed to the space H between the guide rails by welding, clamping, or the like.
It should be noted that, in some embodiments, the rotation hole 3031 and the rotation shaft 305 are integrally disposed, that is, a cylindrical boss adapted to the through hole 2013 is directly disposed on a surface of the sidewall connection portion 303 close to the rotation block 201, so as to implement shaft hole matching.
In this embodiment, the base connecting portion 301 and the sidewall connecting portion 303 are integrally formed. In other embodiments, the sidewall connectors 303 mate with the base connectors 301 to form a detachable connection, and when the spacing H between the rails N is different, the sidewall connectors 303 can be adapted to different base connectors 301.
