Abstract
The utility model discloses an anti-falling device for operating on poles and towers, which comprises a guide rail and anti-falling components, wherein, the guide rail is installed on climbing objects of high building types such as the original steel tower erecting cables and the like. The anti-falling components comprise two base plates arranged in parallel, a connecting plate, an upper pin and a lower pin and an upper brake bar and a lower brake bar matched with the guide rail in a brake way. The anti-falling device for operating on poles and towers has the advantages that the structure is simple, and the utilization is convenient, the device can be used as long as the vertical striped guide rail is arranged on the climbing objects, once the highrise operator slips down, the brake bar of the utility model can be instantly matched with the guide rail in a brake way to prevent the staff from falling, thus the life safety of the highrise operators can be effectively protected.
Description
Technical field
The utility model relates to a kind of high-altitude falling proof device, particularly a kind of shaft tower operation falling proof device.
Background technology
In industries such as the power transmission and transformation of power system, telecommunication, chemical industry work high above the ground is arranged all, need ascend a height; In building field, the construction of skyscraper, maintenance, maintenance also often relate to ascend operation, owing to there is not reliable falling-proof safety device, safety code can't be implemented, and causes the accident in the ascend operation to take place frequently.China's power industry regulation, ascend operation must not lose the safety belt protection, and in fact, shaft tower can't be brought into play the safety belt effect up and down.In order to ensure the life safety of power construction personnel in the process of shaft tower up and down, researched and developed multiple catching device successively, wherein the patent No. is that the utility model patent specification of ZL96227757.6 discloses a kind of " falling proof device of ascending a height ", this falling proof device of ascending a height includes a special cat ladder or special rod member, and one is enclosed within on special cat ladder right column or the special rod member and can be along right column or the upper and lower mobile anti-falling device of special rod member.Special cat ladder is formed by saving in last joint, following joint and the 3-20 joint, marks time the left column and middle being equipped with of right column of cat ladder, and the support member that is used to be connected on the high structures is housed in the cat ladder side.Anti-falling device one end is a crotch shape, in the middle of the crotch is circular shape, the right column that penetrates special cat ladder or special rod member, opening edge at crotch stretches out a bearing pin, distance between bearing pin top and the crotch top is when operation, diameter less than special cat ladder right column or special rod member, can be by the supporter of mark time on the special cat ladder right-hand member or special rod member, a truckle is housed in the crotch side, can rotate around pulley spindle, the pulley below has spring to withstand on the pin, and the distance that pulley ejects is regulated with nut in the pin lower end.The catching device complex structure of said structure, and need matching used with it speciality cat ladder, these have all limited its range of application.
The utility model content
The purpose of this utility model is to overcome above technological deficiency, provides a kind of simple in structure, easy to use, need not the shaft tower operation falling proof device of special ladder.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of shaft tower operation falling proof device, include guide rail and anti-fall assembly, it is characterized in that: described anti-fall assembly includes two substrates that be arranged in parallel, connecting plate, two bearing pins up and down, two brake bars up and down, two substrates are mutually permanently connected by two bearing pins, every substrate is provided with row's pulley and guide rail is slidingly matched, one end of last brake bar is articulated in upper pin, the other end is articulated in connecting plate, one end of following brake bar is articulated in lower bearing pin, the other end is articulated in connecting plate, connecting plate is provided with and is used for the through hole that is connected with safety belt, two brake bar ends relative with guide rail are respectively equipped with the zigzag projection that cooperates with the guide rail braking up and down, be with torsion spring on the upper pin, one end of torsion spring props up substrate, and the other end props up brake bar, and this torsion spring makes brake bar zigzag projection produce the trend of presses against track.
The beneficial effects of the utility model are: the utility model is simple in structure; easy to use; the guide rail that only needs to set up vertical bar shaped on the climbing thing can use; in a single day work high above the ground personnel slip; the utility model brake bar can cooperate the personnel of preventing to drop with the guide rail braking immediately, can effectively protect work high above the ground personnel's life safety.
Below in conjunction with accompanying drawing the utility model is described in further detail

The specific embodiment
To shown in Figure 7, a kind of shaft tower operation falling proof device includes guide rail and anti-fall assembly as Fig. 1.Guide rail is the steel of vertical bar shaped, is installed in to climb on the thing, and guide rail can be an I-steel, also can be the T-shape steel, and the utility model preferably adopts the T-shape steel.Anti-fall assembly includes two substrates that be arranged in parallel 4, connecting plate 1, two bearing pins, two brake bars 3,5 that cooperate with the guide rail braking up and down up and down.Respectively be provided with two row's pulleys 6, two substrates 4 on two substrates 4 and interconnect fixingly by two bearing pins up and down, pulley 6 cooperates with the bottom surface rolling of T-shape steel.One end of last brake bar 3 is articulated in upper pin, and the other end is articulated in connecting plate 1, and an end of following brake bar 5 is articulated in lower bearing pin, and the other end is articulated in connecting plate 1.Connecting plate 1 is provided with and is used for the through hole that is connected with safety belt, and two brake bar ends relative with guide rail are respectively equipped with the sawtooth that cooperates with the guide rail braking up and down.Upper pin is provided with torsion spring 2, and these torsion spring 2 one ends prop up brake bar 3, and the other end props up substrate 4.
When the utility model used, anti-fall assembly was stuck on the T-shape steel, and work high above the ground personnel's safety belt ties up on the through hole of connecting plate 1.During normality, brake bar props up the T-shape steel under the effect of torsion spring 2 elastic force, sawtooth on the brake bar and the bottom surface contact friction of T-shape steel, the work high above the ground personnel whereabouts of in a single day slipping like this, brake bar 3,5 can block guide rail securely and produces a frictional force that makes progress and stop the operating personnel to continue to fall up and down.When the operation personnel need up and down the tower bar, only need to carry connecting plate 1, the elastic force that overcomes torsion spring 2 rotates to an angle brake bar to break away from and the contacting of T-shape steel, so just can easily about the tower bar.
As a kind of improvement embodiment of the present utility model, respectively be provided with a safety block on two substrates 4, the slide surface of safety block and guide rail over against and leave the gap.The timely like this situations such as pulley 6 accidental damages that occur on the substrate 4, safety block can also prop up guide rail, is unlikely to whole anti-fall assembly to come off from guide rail, causes the work high above the ground casualties.
Certainly; protection domain of the present utility model is not limited only to above-mentioned embodiment; torsion spring 2 also can be located on the lower bearing pin, can also on two bearing pins torsion spring be set all, and any improvement to the utility model unsubstantiality all should be within protection domain of the present utility model.
