Description

Building construction hoisting device

Technical Field

The invention relates to the technical field of hanging basket equipment for external use of buildings, in particular to a lifting device for building construction.

Background

As construction equipment for manned high-altitude operation, the high-altitude operation hanging basket has high danger in the use process and is one of important danger sources on a construction site. However, the hanging basket is not incorporated into the management scope of special equipment so far, and does not belong to the application range of the safety supervision and management regulation of the construction hoisting machinery issued by the ministry of housing and construction. Due to the lack of national uniform hanging basket construction safety supervision regulations, the safety supervision of hanging basket construction sites in various places is disordered at present.

Due to the lack of a unified, scientific, effective and definite construction site management method, the periodic detection of the baskets in the construction site is basically lacked or the self-stream is left, so that some mandatory terms in GB19155-2003 high-altitude operation baskets are tied up. For example, in the process of basket leasing and using, the exceeding steel wire rope is not scrapped, basket parts of different manufacturers are mixed and loaded, and the hidden danger of accidents is caused by safe basket construction.

In GB19155 and related regulations, the construction of the outer wall hanging basket needs to be fallen to the ground every day. And checking all parts, connection conditions and the like of the hanging basket, performing operation tests on the hanging basket, and checking the working condition of the safety device. However, the inspection method has the defects that the working steel wire rope cannot be inspected on the ground daily and the recent use condition of the steel wire rope cannot be known. The length span of the steel wire rope is close to the height of the whole building, the steel wire rope is easy to corrode by air or rainwater, and the steel wire rope is close to the wall surface of the building, so that a lot of building dust and impurities are attached to the surface of the steel wire rope, when the hanging basket ascends or descends, the impurities enable the steel wire rope to pass through the lifting motor, the friction between the steel wire rope and the motor and the friction inside the steel wire rope are increased, the conditions of rope loosening, wire breaking and the like of the steel wire rope are easy to cause, if the conditions are discovered in time, the steel wire rope is damaged before the annual inspection date, and casualties are easy to cause during use.

Therefore, the building construction lifting device is provided.

Disclosure of Invention

The invention aims to provide a building construction lifting device, which removes most impurities on a steel wire rope through a scraper and further cleans the steel wire rope through a cleaning cloth on a splicing block so as to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

a construction hoist includes.

A hanging basket, a safety lock and a steel wire rope;

two wire rope symmetry passes the hanging flower basket both sides, install the motor that drives wire rope in the hanging flower basket, the safety lock passes through the bolt fastening in the hanging flower basket both sides, wire rope passes the safety lock.

Preferably, the cleaning device comprises a base fixed on the hanging basket through bolts, a plurality of splicing blocks are arranged on the base, cleaning blocks are arranged on the inner surfaces of the splicing blocks, cleaning cloth is sleeved on the cleaning blocks, the support is installed on the base through screws, the supporting plate is installed on the support through screws, a pretreatment assembly is arranged on the supporting plate, and the pretreatment assembly cleans the steel wire rope in advance and stabilizes the splicing blocks.

Because the position of wire rope is close to the building wall, when the building construction, impurity such as dust, silt splashes to wire rope on, and impurity such as silt, small stone easily glues in sneaking into the gap between the wire rope, when the hanging flower basket rises or descends, adheres to at the inside wearing and tearing of wire rope aggravation wire rope. In addition, in the morning, impurities attached to the wire rope react with dew, and the wire rope is easily corroded.

In order to reduce friction and corrosion of impurities on the steel wire rope and avoid blockage caused by the impurities entering the safety lock when the hanging basket works, a cleaning device is arranged at the fixed position of the steel wire rope and the hanging basket.

Specifically do, will piece together the piece respectively the attached installation around wire rope, it is fixed to utilize the pretreatment subassembly to piece together the piece, when piece together the combination, the shape and the wire rope of combination mutually support, because wire rope's winding angle is great, when wire rope and piece together the relative motion of taking place vertical direction, piece together the piece of combination will take place to rotate, the piece is pieced together to the cooperation is epaxial cleaning cloth, with the dust on the wire rope, water, the greasy dirt blocks outside the safety lock, guarantees that the safety lock does not take place trouble such as jam.

Most impurities on the steel wire rope are removed through the pretreatment assembly before the steel wire rope passes through the splicing blocks, so that the cleaning cloth on the splicing blocks can mainly clean a small amount of impurities on the surface of the steel wire rope, the replacement frequency of the cleaning cloth is reduced, and the service life of the cleaning cloth is prolonged.

Compared with the common wiping mode that the cleaning cloth is vertically arranged, the friction force of the cleaning cloth is large when the cleaning cloth is used for wiping the steel wire rope, the cleaning cloth is easy to tear, and the service life of the cleaning cloth is short.

The cleaning cloth is industrial wiping cloth, and is pure in texture, firm and not easy to break, high-efficiency water and oil absorption are realized, and even if the cleaning cloth is damaged, the damage to the steel wire rope is avoided.

Preferably, the pretreatment assembly comprises a sleeve fixedly mounted on the support plate, the diameter of the sleeve is larger than the combined diameter of the plurality of segments, and a cleaning ring is fixedly mounted on the upper portion of the sleeve.

Furthermore, the cleaning ring is provided with an inclined chamfer.

Further, clean ring is including adopting the mounting ring of bolt installation at the sleeve roof, it has the scraper to inlay in the mounting ring, the shell is installed to the screw thread on the mounting ring.

Further, the scraper is made of plastic, the shape of the scraper is matched with that of the steel wire rope, and the scraper rotates around the steel wire rope when the hanging basket ascends or descends.

Furthermore, the scraper is installed in the mounting ring in a splicing mode.

Further, the sleeve and the split are made of transparent materials.

The steel wire rope is pre-cleaned by the aid of the cleaning ring, the scraper in the cleaning ring is matched with the steel wire rope, and when the hanging basket ascends or descends, the cleaning ring rotates and scrapes impurities on the steel wire rope. The cross-section of cleaning ring is the round platform type, when hanging down impurity on the wire rope, gets rid of impurity to the inclined plane on through cleaning ring rotation to reach the effect of the impurity on the clearance cleaning ring.

The splicing blocks are sleeved and fixed by the lower parts of the sleeves, so that the pressure of the cleaning cloth on the splicing blocks on the steel wire rope is ensured.

The sleeve and the splicing block are made of transparent materials, so that workers can observe the use condition of the cleaning cloth more clearly, the cleaning cloth can be replaced in advance through observation in areas with more sand content in the air, and the cleaning effect of the steel wire rope is guaranteed.

The cleaning ring clears away the impurity on the wire rope surface through inlaying at its inside scraper, and the scraper passes through the shell to be installed on the collar, when the scraper needs to be changed, can directly pull down the shell, lift the scraper off, again with new scraper embedding mount pad, it can to cover the shell. In consideration of friction between the scraper and the steel wire rope, the scraper is made of UHMWPE (ultra high molecular weight polyethylene) plastic, has the characteristics of high wear resistance, low density, acid and alkali resistance and the like, is suitable for being used in construction sites, still keeps the performance of the scraper unchanged in long-time sunlight irradiation and rainwater soaking, and is low in price. Most importantly, the strength of the steel wire rope is lower than that of the steel wire rope, and the steel wire rope cannot be damaged when the steel wire rope is rubbed with the steel wire rope.

It should be noted that the housing and the mounting ring are connected by screw threads, and the vertical height of the housing is greater than the screw thread height of the mounting ring, so that even if the housing is completely screwed into the mounting ring, the housing does not press the scraper to affect the rotation of the scraper. After the shell is screwed into the mounting ring, the scraper still protrudes out of the shell so as to conveniently discharge impurities.

Preferably, fixed mounting has the spiral piece in the base, the spiral piece is the cartridge type, the upper portion and the wire rope of spiral piece are mutually supported, the fixed orifices has been seted up to spiral piece lower part, install in the fixed orifices and scrape the piece, scrape the impurity that the piece is arranged in clearing up the wire rope gap.

Furthermore, a spring is fixedly installed in the fixing hole and fixedly connected with the scraping block.

Further, the top end of the scraping block is conical.

Further, the fixing hole is not perpendicular to the axis of the steel wire rope.

Cleaning cloth through with wire rope's contact, with impurity transfer to cleaning cloth from wire rope, during this period, some impurity can pile up in wire rope's the gap, at this moment, just take place to cooperate through the upper portion of spiral piece and wire rope, make the spiral piece take place to rotate to scrape the impurity in the wire rope gap through the piece of scraping of its bottom. The top of scraping the piece is the toper, makes when scraping the impurity that the piece got rid of on the wire rope, impurity can't stop on scraping the piece to fall from the outer loop.

It should be noted that, because of the scraping of rotation form, before wire rope produced the effort to scraping the piece, scrape the piece and have taken place the rotation, so wire rope only has frictional force to the power that scrapes the piece and produce, through scraping the spring that the piece was placed, when scraping the piece and receiving wire rope reaction force when too big, through the mode that compression spring made scraping the piece and retreat, offset reaction force.

Because the upper portion of spiral piece and wire rope clearance fit, if scrape the most advanced of piece between and directly support the gap of wire rope, when wire rope and spiral piece take place relative displacement, the scraper takes place the skew to the wire rope gap, causes to scrape the condition that the tip is to inaccurate the wire rope gap. The initial state of the tip of the scraping block and the gap of the steel wire rope is not aligned to the angle of the fixed hole and the axis of the steel wire rope, and when the steel wire rope and the spiral block are in relative displacement, the tip of the scraping block is abutted to the gap of the steel wire rope.

Similarly, the scraping block can be arranged on the spiral block in a splicing mode, and the scraping block can be replaced in time when damaged.

Preferably, the base includes the outer loop of fixed mounting on the hanging flower basket, the inner ring is installed to the outer loop internal rotation, the spout has been seted up on the roof of inner ring, piece together piece bottom fixed mounting have with the spout slider of mutually supporting, the support is telescopic bracket.

Furthermore, the upper end and the lower end of each splicing block are respectively provided with a convex block, and the cleaning blocks are arranged between the convex blocks of the splicing blocks through magnets.

Different from the cleaning mode of scraper on the mount pad, cleaning cloth is after long-time work, and the adnexed impurity on surface increases gradually, can reduce gradually to wire rope's wiping effect, just needs to change cleaning cloth this moment.

Specifically, after the hanging basket descends to the ground, the supporting plate is lifted upwards, the limiting protrusions are arranged on the support, when the supporting plate is lifted to a certain height, the support is kept at the set height by the limiting protrusions on the support, the sleeve is separated from the splicing blocks, the splicing blocks are sequentially drawn out along the inner ring sliding grooves, and the cleaning blocks are detached from the splicing blocks. The cleaning cloth on the cleaning block is of a customized type, the cleaning cloth can be sleeved on the cleaning block through the bulge at the rear of the cleaning block, and the cleaning cloth does not deviate when the cleaning cloth cleans the steel wire rope.

The upper end and the lower end of the splicing block are provided with the convex blocks, and the cleaning blocks are fixed on the inner side wall of the splicing block by utilizing the magnets, so that the cleaning blocks can be kept fixed when the cleaning cloth wipes the steel wire rope.

Preferably, the sleeve is slidably mounted on the support plate, the diameter of the lower portion of the sleeve is larger than that of the upper portion of the sleeve, an oblique chamfer is formed at the junction of the large diameter and the small diameter inside the sleeve, and an oblique chamfer is formed at the periphery of the top of the splicing block.

Furthermore, the upper part of the sleeve is in a conical shape with a small upper part and a big lower part.

Furthermore, balls are embedded in the inclined chamfers arranged on the periphery of the top of the splicing block.

When the hanging flower basket rises, utilize sleeve and wire rope's frictional force, make the sleeve move down, at this moment, the piece of piecing together that is located the big footpath of sleeve lower part and takes place to contact with the path on sleeve upper portion, because the oblique chamfer of piecing together the peripheral seting up in piece top, piece together the piece very easily just can take place to cooperate with the path on sleeve upper portion, specifically be, the polylith piece is pieced together constantly to drawing close to wire rope under the extrusion on sleeve upper portion for cleaning cloth on the piece inner wall produces pressure in order to realize the effect of wiping to wire rope.

The cleaning cloth is firm and is an industrial cleaning cloth, so the replaced cleaning cloth can still be normally used after being rinsed again, but the thickness of the cleaning cloth is reduced due to abrasion and shrinkage along with the increase of the use times, and at the moment, if the diameter of the upper part of the sleeve is not changed, when a hanging basket is lifted, the pressure given to splicing blocks by the sleeve is reduced, and the wiping effect on a steel wire rope is influenced. Therefore, the upper part of the sleeve is in a conical shape with a small upper part and a big lower part, so that the shrunk cleaning cloth can still have a good cleaning effect on the steel wire rope.

It is considered that the upper part of the sleeve needs to bear against the tile to exert pressure on it as the basket is raised, affecting the normal rotation of the tile. Therefore, balls are embedded in the inclined chamfers arranged on the periphery of the top of the splicing block, and rolling friction of the balls on the sleeve replaces original sliding friction, so that normal work of the splicing block is guaranteed.

When the hanging basket descends, the sleeve is subjected to upward friction of the steel wire rope, the sleeve and the base move upwards relatively, the upper portion of the sleeve is separated from the splicing blocks, inward tightening force of the splicing blocks is lost, and the cleaning effect of the splicing blocks on the steel wire rope is reduced.

It can be understood that in the process of lifting the hanging basket, the splicing blocks clean the steel wire rope once, so that when the hanging basket descends, impurities on the steel wire rope are less, the cleaning effect of the cleaning cloth on the steel wire rope is lower, and the cleaning benefit of the cleaning cloth on the steel wire rope is less than the loss of the cleaning cloth.

It should be noted that, because the diameter of the bottom of the mounting ring is larger than the diameter of the upper part of the sleeve of the support plate, the distance of the downward movement of the sleeve is fixed, and the cleaning ring is not influenced by the splicing block when in operation.

The juncture of the large diameter and the small diameter of the sleeve is conical, so that the upper part of the sleeve can be better contacted with the splicing block and is stably and tightly sleeved on the periphery of the steel wire rope.

Preferably, the cleaning device is mounted on a safety lock.

The safety lock on the hanging basket has the function that when the descending speed of the hanging basket exceeds a certain value or when the hanging basket inclines or the working rope is broken and loosened, the safety lock immediately locks the steel wire rope to stabilize the hanging basket. However, when the steel wire rope attached with a large amount of impurities is matched with the safety lock for a long time, the impurities are easy to block parts in the lock, so that the safety lock fails. However, if the cleaning device is directly mounted on the safety lock, the wire rope passing through the safety lock each time is processed, so that the problem can be solved.

Compared with the prior art, the invention has the beneficial effects that:

1. the wire rope cleaning device is provided with a pretreatment assembly, the wire rope is pre-cleaned through a cleaning ring, a scraper in the cleaning ring is matched with the wire rope, and when a hanging basket ascends or descends, the cleaning ring rotates and scrapes impurities on the wire rope. The cross-section of cleaning ring is the round platform type, when hanging down impurity on the wire rope, gets rid of impurity to the inclined plane on through cleaning ring rotation to reach the effect of the impurity on the clearance cleaning ring.

2. Through will piecing together the piece respectively attached install around wire rope, utilize the sleeve will piece together the piece fixed, piece together the piece when making up, the shape and the wire rope of combination mutually support, because wire rope's winding angle is great, when wire rope and piece together the relative motion of taking place vertical direction, piece together the piece of combination will take place to rotate, the cooperation piece together the piece on the piece clean cloth, with the dust on the wire rope, water, the greasy dirt blocks outside the safety lock, guarantees that the safety lock does not take place trouble such as jam.

3. The upper part of the spiral block is matched with the steel wire rope, so that the spiral block rotates, and impurities in a gap of the steel wire rope are scraped by the scraping block at the bottom of the spiral block. The top of scraping the piece is the toper, makes when scraping the piece and get rid of the impurity on the wire rope, impurity can't stop on scraping the piece to fall down in the outer loop.

Detailed Description

Referring to fig. 1 to 9, the present invention provides a lifting device for building construction, which has the following technical scheme:

a construction hoist comprising:

a hanging basket, a safety lock and a steel wire rope 1;

the two steel wire ropes 1 symmetrically penetrate through two sides of the hanging basket, motors matched with the steel wire ropes 1 are installed in the hanging basket, the safety locks are fixed on two sides of the hanging basket through bolts, and the steel wire ropes 1 penetrate through the safety locks.

Since the steel cable 1 is detached from the basket only when the steel cable is inspected annually or damaged, the present invention must be mounted on the basket together with the safety lock when the steel cable 1 is mounted on the basket.

Specifically, after the outer ring 6 is mounted on the safety lock by screws, the screw block 606 is mounted in the outer ring 6, the screw block 606 can rotate in the outer ring 6, and then, the inner ring 602 is also mounted in the outer ring 6, and the inner ring 602 is located above the screw block 606. The sleeve 3 is arranged in the supporting plate 4, the supporting plate 4 is fixed on the bracket 5 through screws, the mounting ring 2 can be directly fixed on the top wall of the sleeve 3 through welding, the scraper 202 is arranged in the mounting ring 2, and the shell 201 is fixed on the mounting ring 2 through threads. The steel wire rope 1 passes through the sleeve 3, the base, the spiral block 606, the safety lock and the hanging basket from the cleaning ring in sequence, the splicing block 601 can be placed and installed at the last, the support plate 4 and the sleeve 3 are lifted upwards, and the limit bulges on the support 5 are utilized, so that when the support plate 4 is lifted to a certain height, the limit bulges on the support 5 keep the support 5 at the set height. At this time, the distance between the bottom surface of the sleeve 3 and the inner ring 602 is smaller than the height of the tiles 601, the tiles 601 are respectively mounted in the slide grooves 605 formed in the inner ring 602 by the sliders 604 at the bottom of the tiles 601, and the positions of the tiles 601 are adjusted by the rotation of the inner ring 602 in the outer ring 6, so that all the tiles 601 are attached around the wire rope 1.

The first embodiment is as follows:

the working principle of the invention is that the steel wire rope 1 is firstly pre-cleaned through the cleaning ring, the scraper 202 in the cleaning ring is matched with the steel wire rope 1, and when the hanging basket ascends or descends, the cleaning ring rotates and scrapes off impurities on the steel wire rope 1. The cross-section of cleaning ring is the round platform type, when hanging down the impurity on wire rope 1, gets rid of impurity to the inclined plane on through cleaning ring rotation to reach the effect of the impurity on the clearance cleaning ring.

When the hanging basket ascends, the sleeve 3 is moved downwards by utilizing the friction force between the sleeve 3 and the steel wire rope 1, at the moment, the splicing blocks 601 positioned in the large diameter at the lower part of the sleeve 3 are in contact with the small diameter at the upper part of the sleeve 3, and the splicing blocks 601 can be easily matched with the small diameter at the upper part of the sleeve 3 due to the inclined chamfer angle arranged at the periphery of the top of the splicing blocks 601, so that the splicing blocks 601 at the upper part of the sleeve 3 are folded inwards, and the splicing blocks 601 are continuously drawn close to the steel wire rope 1 under the extrusion of the upper part of the sleeve 3, so that the cleaning cloth on the inner wall of the splicing blocks 601 generates pressure on the steel wire rope 1 to realize the wiping effect.

After the cleaning cloth works for a long time, the attached impurities on the surface are gradually increased, the wiping effect on the steel wire rope 1 is gradually reduced, at the moment, the cleaning cloth needs to be replaced, after the hanging basket descends to the ground, the supporting plate 4 is lifted upwards, the bracket 5 is provided with the limiting protrusions, when the supporting plate 4 is lifted to a certain height, the bracket 5 is kept at the set height by the limiting protrusions on the bracket 5, the sleeve 3 at the moment is separated from the split blocks 601, the split blocks 601 are sequentially pulled out along the sliding grooves 605 of the inner ring 602, and the cleaning blocks 603 are detached from the split blocks 601. The cleaning cloth on the cleaning block 603 is in a customized shape, the cleaning cloth can be sleeved on the cleaning block 603 through a protrusion behind the cleaning block 603, and the cleaning cloth does not deviate when wiping the steel wire rope 1.

The cleaning cloth transfers impurities from the steel wire rope 1 to the cleaning cloth through contact with the steel wire rope 1, during the period, a part of impurities can be accumulated in the gap of the steel wire rope 1, at the moment, the spiral block 606 rotates through the matching of the spiral block 606 arranged at the lower part of the inner ring 602 and the steel wire rope 1, and the impurities in the gap of the steel wire rope 1 are scraped through the scraping block 607 at the bottom of the spiral block. The top of scraping the piece 607 is the toper, and when making scraping the piece 607 and getting rid of the impurity on the wire rope 1, impurity can't stop on scraping the piece 607 to fall from outer ring 6.

When the hanging basket descends, the sleeve 3 is subjected to upward friction force of the steel wire rope 1, the sleeve 3 and the base move upwards relatively, the upper portion of the sleeve 3 is separated from the splicing blocks 601, inward tightening force of the splicing blocks 601 is lost, and the cleaning effect of the splicing blocks 601 on the steel wire rope 1 is reduced. The reason is that the splicing block 601 has already cleaned the steel wire rope 1 once, so when the hanging basket descends, the impurities on the steel wire rope 1 are less, the cleaning effect of the cleaning cloth on the steel wire rope 1 is lower at the moment, and the cleaning benefit of the cleaning cloth on the steel wire rope 1 is less than the loss of the cleaning cloth.

The second embodiment:

what has been described above is that in the east region where the amount of wind sand is low in the air, when the hanging basket is suspended, the impurities accumulated on the wire rope 1 are less, and the splicing block 601 only needs to clean the wire rope 1 when the hanging basket is lifted, so that the effects of daily maintenance and prevention of blockage of the safety lock can be achieved. When the hanging basket is constructed in the high altitude, the wind speed is high, and more wind sand can be accumulated on the steel wire rope 1 in a short time. When the hanging basket descends, the risk that the safety lock is blocked by impurities is increased, so the cleaning scheme of the steel wire rope 1 in the area can be changed into the cleaning scheme that the steel wire rope 1 is cleaned when the hanging basket ascends or descends.

Specifically, on the basis of the first embodiment, a set of cleaning device is arranged below the motor in the hanging basket and used for preventing the safety lock from being blocked and preventing the steel wire rope 1 from being worn.

Obviously, this solution would directly increase the cost of use and require more time when changing the cleaning cloth and the doctor blade 202. However, workers working in such environments can add a guarantee to their personal safety.
