Description

A construction hanging basket suitable for high-altitude operations of steel structure main body

Technical Field

The present application relates to the technical field of steel structure construction tools, and in particular to a construction hanging basket suitable for high-altitude operations on steel structure main bodies.

Background Art

At present, with the development of social economy and the popularization of prefabricated buildings, steel structure main body is widely used in urban housing construction projects due to its own advantages. In the development process in recent years, due to the continuous improvement of the internal construction requirements of the steel structure main body and the continuous improvement of corresponding laws and regulations, since the promulgation and implementation of the new safety law, higher requirements have been put forward for safety management in the construction of steel structure main body.

During the main construction of the steel structure, it is difficult to build a construction platform due to the influence of the deep structure. Usually, construction workers can only stand on the steel structure with safety ropes tied around their bodies during the process of tightening the bolts of steel components and welding the nodes.

With respect to the above-mentioned related technologies, the inventors found that, due to factors such as the angle of the steel structure, welding operation of some welds is inconvenient, which may result in loose welding and possible welding leaks; the risk factor for operators working at heights is also relatively high.

Summary of the invention

In order to facilitate construction operations and improve the safety of construction operations, the present application provides a construction hanging basket suitable for high-altitude operations of steel structure main bodies.

The present application provides a construction hanging basket suitable for high-altitude operations of steel structure main bodies, which adopts the following technical solutions:

A construction hanging basket suitable for high-altitude operation of a steel structure main body, comprising:

Basket body;

A moving mechanism is slidably arranged on the upper flange plate of the H-shaped steel beam of the main body of the steel structure;

A load-bearing frame connected between the basket body and the moving mechanism;

Anti-dumping mechanism, arranged on both sides of the load-bearing frame;

The basket bodies are provided with two, which are symmetrically arranged on both sides of the load-bearing frame.

By adopting the above technical scheme, the moving mechanism can move along the H-shaped steel beam of the steel structure main body and support the load-bearing frame. The baskets are respectively arranged on both sides of the H-shaped steel beam, which can play a certain role of balancing and counterweighting. Because it is possible that the operator will only go down into the basket on one side, the anti-dumping mechanism can balance the hanging basket when the weight of the baskets on both sides is different, so that the hanging basket is not easy to tilt. When the operator performs welding, tightening bolts and other operations in the basket, movement and operation are more convenient, and the safety of high-altitude operations is also improved.

Optionally, the moving mechanism includes:

Moving boxes;

Moving wheels, rotatably connected to both sides of the moving box;

A threaded sleeve, rotatably connected to the moving box;

The locking screw is threadedly connected to the threaded sleeve and passes downward out of the moving box;

The anti-skid plate is connected to the lower end of the locking screw.

By adopting the above technical solution, the locking screw will move along the direction of the threaded sleeve by rotating the threaded sleeve. When the moving box is moved into place, the threaded sleeve is rotated to lower the locking screw, and the anti-skid plate can resist the top surface of the flange plate on the H-shaped steel beam, thereby fixing the position of the hanging basket and preventing the hanging basket from deviating from its position during construction.

Optionally, the moving mechanism further includes a connecting shaft connecting two relatively moving wheels, and the construction hanging basket further includes a brake mechanism, which includes:

Brake plate, hinged in the moving box;

The brake piece is arranged on the side wall of the brake plate facing the connecting shaft.

By adopting the above technical solution, the brake plate is rotated toward the connecting shaft, and the brake plate will be pressed onto the connecting shaft, and there will be friction between the brake plate and the connecting shaft, which will stop the moving wheel and make the moving box unable to move. Together with the anti-skid plate, the position of the hanging basket is fixed, thereby improving the control effect of the hanging basket.

Optionally, the brake mechanism further includes:

The brake screw is rotatably arranged in the moving box;

A slider, threadedly connected to the brake screw and slidably connected to the brake plate;

The transmission assembly is connected between the threaded sleeve and the brake screw.

By adopting the above technical solution, when the threaded sleeve is rotated to lower the anti-skid plate, the transmission assembly will transmit the torque to the brake screw, the brake screw and the threaded sleeve will rotate synchronously, the brake screw drives the slider to slide, and the slider pushes the brake plate toward the connecting shaft to achieve the effect of braking the connecting shaft. Only by rotating the threaded sleeve can the anti-skid plate and the brake plate be fixed to the hanging basket in dual positions, which is convenient and quick.

Optionally, the transmission assembly is a bevel gear set or a staggered helical gear set.

By adopting the above technical solution, the change in direction of the rotational torque of the threaded sleeve can be transmitted to the brake screw by using a bevel gear set or a staggered axis helical gear set.

Optionally, the combination of the connecting shaft and the moving wheel is provided with two groups; the brake screw comprises two ends with opposite thread rotation directions, and the two ends are respectively threadedly connected with a slider.

By adopting the above technical solution, when the brake screw rotates, the two sliders will slide synchronously, and the two brake plates will also move synchronously, so that the brake screw can control the two brake plates, thereby improving the braking effect of the hanging basket and simplifying the operation.

Optionally, the anti-dumping mechanism includes:

An anti-tipping frame is arranged on the load-bearing frame;

The anti-tipping wheel is rotatably connected to the anti-tipping frame and rolls against the bottom surface of the upper flange plate of the H-shaped steel beam of the main body of the steel structure.

By adopting the above technical solution, the moving wheels and anti-dumping wheels are respectively located on the upper and lower sides of the flange plate of the H-shaped steel beam of the steel structure main body. When the moving box tends to tilt horizontally, the corresponding moving wheels or anti-dumping wheels will press against the H-shaped steel beam to prevent dumping.

Optionally, the anti-dumping mechanism further comprises a connecting rod, one end of which is slidably connected to the load-bearing frame, and the other end of which is connected to the anti-dumping frame.

By adopting the above technical solution, when the hanging basket is installed on the H-shaped steel beam, the connecting rod can be slid open, and after the moving mechanism is in place, the connecting rod can be slid toward the H-shaped steel beam until the anti-dump wheel reaches the installation position, making the installation of the hanging basket more convenient; at the same time, the slidable connecting rod can also make the hanging basket suitable for H-shaped steel beams of various cross-sectional sizes, thereby improving the applicability of the hanging basket.

Optionally, the anti-dump frame is slidably connected to the connecting rod.

By adopting the above technical solution and adjusting the height position of the anti-dump frame on the connecting rod, the anti-dump wheel can better abut the H-shaped steel beam, so that the hanging basket can move or park on the H-shaped steel beam more smoothly; at the same time, the anti-dump frame can be raised and lowered, which can also make the hanging basket suitable for H-shaped steel beams with various cross-sectional sizes.

Optionally, a lifting ear is fixedly connected to the load-bearing frame.

By adopting the above technical solution, the lifting ears can facilitate the lifting and transportation of the hanging basket. The hanging basket can be sent to the H-shaped steel beam of the steel structure main body by a tower crane on the construction site, which is easy to operate.

In summary, the present application includes at least one of the following beneficial technical effects:

1. The mobile mechanism can move along the H-shaped steel beam of the main body of the steel structure and support the load-bearing frame. The baskets are respectively arranged on both sides of the H-shaped steel beam, which can play a certain role in balancing the weight. Because it is possible that the operator will only go down to one side of the basket, the anti-dumping mechanism can balance the hanging basket when the weight of the baskets on both sides is different, so that the hanging basket is not easy to tilt. When the operator performs operations such as welding and tightening bolts in the basket, the movement and operation are more convenient, and the safety of high-altitude operations is also improved;

2. When the threaded sleeve is rotated to lower the anti-skid plate, the transmission assembly will transmit the torque to the brake screw, the brake screw and the threaded sleeve will rotate synchronously, the brake screw drives the slider to slide, and the slider pushes the brake plate toward the connecting shaft to achieve the effect of braking the connecting shaft. Only by rotating the threaded sleeve, the anti-skid plate and the brake plate can be fixed to the hanging basket in dual positions, which is convenient and quick;

3. The moving wheels and anti-dumping wheels are located on the upper and lower sides of the flange plate of the H-shaped steel beam of the main body of the steel structure. When the moving box tends to tilt horizontally, the corresponding moving wheels or anti-dumping wheels will press against the H-shaped steel beam to prevent it from tipping.

4. When installing the hanging basket on the H-shaped steel beam, the connecting rod can be slid away. After the moving mechanism is in place, the connecting rod can be slid toward the H-shaped steel beam until the anti-dumping wheel reaches the installation position, making the installation of the hanging basket more convenient; at the same time, the sliding of the connecting rod can also make the hanging basket suitable for H-shaped steel beams of various cross-sectional sizes, improving the applicability of the hanging basket;

5. By adjusting the height of the anti-dump frame on the connecting rod, the anti-dump wheel can better contact the H-shaped steel beam, making the hanging basket move or park on the H-shaped steel beam more stable; at the same time, the anti-dump frame can be raised and lowered, which can also make the hanging basket suitable for H-shaped steel beams with a variety of different cross-sectional sizes.

DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with Figures 1 to 5.

The present application proposes a construction hanging basket suitable for high-altitude operation of a steel structure main body, referring to Figures 1 and 2, comprising a mobile mechanism 2, a load-bearing frame 3, a basket body 1, a brake mechanism 5, and an anti-dumping mechanism 4. The mobile mechanism 2 is arranged on the H-shaped steel beam of the steel structure main body, the load-bearing frame 3 is fixedly connected to the mobile mechanism 2, the brake mechanism 5 is arranged on the mobile mechanism 2, the anti-dumping mechanism 4 is arranged on both sides of the load-bearing frame 3, and the basket body 1 is fixedly connected to both sides of the load-bearing frame 3.

1 and 3, the mobile mechanism 2 includes a mobile box 21, a mobile wheel 22, a threaded sleeve 23, a locking screw 24, an anti-skid plate 25, a connecting shaft 26 and a guide rod 27. The mobile box 21 is a rectangular box body with a cavity therein. The connecting shaft 26 is rotatably connected to the mobile box 21, and the two ends pass through the mobile box 21 and are bolted to the mobile wheels 22 respectively. There are two groups of the combination of the connecting shaft 26 and the mobile wheel 22, which are arranged on the front and rear sides of the moving direction of the mobile box 21. The top wall of the mobile box 21 is vertically rotatably connected with a threaded sleeve 23, and the threaded sleeve 23 is provided with an internal thread. The locking screw 24 is vertically slidably penetrated on the bottom wall of the mobile box 21, and the upper end is threadedly connected to the threaded sleeve 23. A handwheel is fixedly welded on the top of the threaded sleeve 23 to facilitate the operator to rotate the threaded sleeve 23.

The anti-skid plate 25 is a rectangular steel plate, fixedly welded to the bottom end of the locking screw 24, and has anti-skid patterns on the side facing the H-shaped steel beam. The guide rod 27 is vertically fixedly welded to the side of the anti-skid plate 25 connected to the locking screw 24, and is slidably penetrated on the bottom wall of the moving box 21, and plays a role in guiding the vertical movement of the anti-skid plate 25. Four guide rods 27 are provided, respectively located at the four corners of the anti-skid plate 25.

The brake mechanism 5 includes a brake plate 51, a brake piece 52, a brake screw 53, a slider 54 and a transmission assembly 55. The brake plate 51 is hinged on the inner wall of the moving box 21 and is provided with an arc-shaped groove, in which the brake piece 52 is bonded, and the brake piece 52 is made of elastic material. There are four brake plates 51, which are respectively arranged on the inner wall at both ends of the moving direction of the moving box 21. A convex ring with a larger diameter is integrally formed on the connecting shaft 26. When the brake plate 51 rotates, the brake piece 52 can be squeezed to the outer wall of the convex ring, and friction is generated between the convex ring and the brake piece 52, so that the connecting shaft 26 cannot rotate, thereby playing a braking role.

The brake screw 53 is connected to the moving box 21 in a rotational manner along the moving direction of the moving box 21. The two ends of the brake screw 53 are provided with threads of different rotation directions, and are respectively threadedly connected with sliders 54. The slider 54 is a rectangular block, and a sliding column is provided on the side facing the brake plate 51. The brake plate 51 is provided with a waist-shaped hole, and the sliding column is slidably penetrated in the waist-shaped hole. When the brake screw 53 rotates, the two sliders 54 will move relative to or toward each other, and at the same time drive the brake plate 51 to rotate, so as to realize the braking and release of the connecting shaft 26. The transmission assembly 55 is connected between the threaded sleeve 23 and the brake screw 53, and the transmission assembly 55 can be a bevel gear set or a staggered axis helical gear set. In the embodiment of the present application, the transmission assembly 55 is a bevel gear set, and each group has four identical bevel gears. A support plate is vertically welded on the inner bottom wall of the moving box 21, and a rotating shaft is rotatably connected on the support plate. The threaded sleeve 23 transmits the torque to the rotating shaft through a group of bevel gears, and the rotating shaft transmits the torque to the brake screw 53 through a group of bevel gears. There are two groups of brake screw rods 53, sliders 54 and transmission components 55, which respectively control the brake plates 51 on both sides.

In another possible implementation of the present application, the transmission assembly 55 is a staggered helical gear set, a first staggered helical gear is coaxially connected to the threaded sleeve 23, and the two brake screws 53 are respectively provided with a second staggered helical gear meshing with the first staggered helical gear, thereby realizing synchronous driving of the two brake screws 53 by the threaded sleeve 23.

When the position of the hanging basket needs to be fixed, by turning the hand wheel on the threaded sleeve 23, the anti-slip plate 25 can be moved downward and the brake plate 51 can be rotated at the same time, thereby simultaneously realizing the dual anti-movement control of the anti-slip plate 25 abutting the H-shaped steel beam and the brake plate 51 stopping the connecting shaft 26.

1 and 4, the load-bearing frame 3 is a rectangular frame body, which is welded with channel steel, and the bottom is welded to the top of the mobile box 21. Lifting ears 31 are welded on both sides of the load-bearing frame 3, which can facilitate the use of lifting equipment to lift the hanging basket. The load-bearing frame 3 includes beams welded perpendicular to the mobile box 21 on both sides.

4 and 5, the anti-dumping mechanism 4 includes an anti-dumping frame 41, an anti-dumping wheel 42, a connecting rod 43, a limit bolt 44, a positioning screw 45, a rack 46 and a lifting gear 47. The connecting rod 43 is a rectangular cross-section rod, and the top end is slidably sleeved on the crossbeam of the load-bearing frame 3 and is perpendicular to the crossbeam. The top end of the connecting rod 43 is threadedly connected with a positioning screw 45, and the top end of the positioning screw 45 is connected with a hand wheel. By turning the hand wheel, the positioning screw 45 can be tightened against the crossbeam to fix the position of the connecting rod 43 on the crossbeam. A rack 46 is bolted to the connecting rod 43 along the length direction.

The anti-dumping frame 41 is Y-shaped, one end of which is slidably sleeved on the connecting rod 43, and the other two ends are rotatably connected to anti-dumping wheels 42. A lifting gear 47 is rotatably connected to the anti-dumping frame 41, and the lifting gear 47 is meshed with the rack 46. The connecting rod 43 has a threaded hole, and the limit bolt 44 is screwed into the threaded hole to support the anti-dumping frame 41 from the bottom of the anti-dumping frame 41. There are multiple threaded holes along the length direction of the connecting rod 43, and different threaded holes are selected to screw the limit bolts 44 into different H-shaped steel beams. The lifting gear 47 is coaxially connected with a hand wheel to facilitate the adjustment of the lifting and lowering of the anti-dumping frame 41. The anti-dumping wheel 42 rolls against the bottom surface of the upper wing plate of the H-shaped steel beam. The anti-dumping wheel 42 is integrally formed with a flange, and the flange is located on the outside of the H-shaped steel beam, which can guide the movement of the hanging basket and make the movement of the hanging basket more stable.

The moving wheels 22 and the anti-dumping wheels 42 are respectively located on the upper and lower sides of the flange plate of the H-shaped steel beam of the steel structure body. When the moving box 21 tends to tilt horizontally, the corresponding moving wheels 22 or anti-dumping wheels 42 will press against the H-shaped steel beam to prevent dumping.

1 and 2, the basket body 1 is welded with angle steel as the main keel and plain round steel bar as the secondary keel, and a patterned steel anti-skid plate 25 is welded on the bottom of the basket body 1 for workers to step on. The basket body 1 is provided with two, which are welded on both sides of the load-bearing frame 3, and play a balancing role on both sides of the H-shaped steel beam.

The implementation principle of the embodiment of the present application is: when it is necessary to work on the main part of the steel structure, first adjust the position of the anti-dump frame 41, install the limit bolts 44, and then put the hanging basket on the H-shaped steel beam; the moving mechanism 2 aligns the length direction of the H-shaped steel beam, and then moves the connecting rods 43 on both sides toward the H-shaped steel beam until the anti-dump wheel 42 moves to under the upper flange plate of the H-shaped steel beam, and tightens the positioning screw 45; move the hanging basket as a whole to the place to be worked, and turn the handwheel on the threaded sleeve 23 to make the anti-slip plate 25 abut against the H-shaped steel beam and the brake plate 52 press the connecting shaft 26, and the operator can enter the basket body 1 to work by wearing a five-point safety belt.
