Description

Technical Field

[0001] The utility model relates to the technical field of building construction material transfer and lifting equipment, and particularly relates to a construction material transfer and lifting system. Background Art

[0002] In building construction projects, the efficient and safe transfer of construction materials has always been a key link in construction engineering. With the increase in the height and complexity of modern buildings, traditional material transfer methods have gradually been unable to meet the project requirements. Especially during the main structure construction stage, formwork scaffolds are usually used as the load-bearing system at the construction site. The formwork system includes formwork, primary and secondary keels, load-bearing steel pipes, fasteners and other equipment. After the construction of all materials in the formwork system on this floor is completed, they need to be successively transferred upward to the upper area for structure construction. Currently, the materials of the formwork scaffold are mainly hoisted and transferred by using a discharge platform in cooperation with a tower crane. Although this method meets the construction requirements to a certain extent, due to the limitations of the discharge platform, there is still much room for improvement in its efficiency and safety.

[0003] In recent years, with the continuous progress of construction technology, tower cranes have been used more and more widely. Tower cranes are not only used to hoist formwork scaffold materials, but also widely used for the hoisting of other construction materials such as steel bars. However, during the main structure stage, the workload of hoisting steel bars by tower cranes is large. The traditional transfer method using a discharge platform not only occupies a large amount of the effective working time of the tower crane, but also due to the different lengths of steel pipes and keel materials at the construction site, it is extremely easy to cause the risk of falling objects from a height during the hoisting process. The limitations and potential risks of this traditional method make it difficult to effectively improve construction efficiency and safety. Therefore, there is an urgent need for a more efficient and safe construction material transfer system to meet the requirements of modern high-efficiency building construction.

[0004] Currently, the main method used at the construction site is to transfer formwork scaffold materials by using a discharge platform in cooperation with a tower crane. This method has several obvious deficiencies. First, the capacity of the discharge platform is limited, resulting in a small amount of materials transferred each time and low transfer efficiency. Second, a large amount of the effective working time of the tower crane is occupied for hoisting formwork scaffold materials, which in turn affects the hoisting of other construction materials such as steel bars, leading to delays in the overall construction progress. In addition, due to the different lengths of steel pipes and keel materials, there is a risk of materials falling from a height during the hoisting process, posing a serious threat to the safety of the construction site.

[0005] In view of the above deficiencies of the existing technology, there is an urgent need for a new type of construction material transfer and lifting system to solve the problems of low efficiency and poor safety of the traditional transfer method. Content of the Utility Model

[0006] In order to achieve the above utility model purpose and address the above technical problems, the utility model provides a construction material transfer and lifting system.

[0007] Its technical solution includes a tower body attached guide rail arranged on the tower body of a tower crane, a lifting unit arranged on the top of a tower crane standard section, a lift elevator car, and a car top truss arranged on the top of the lift elevator car.

[0008] The lifting unit includes a winch seat, a winch, a slewing fixed pulley, a pulley support frame, a steel wire rope, and a hook.

[0009] The winch seat is arranged on the top of the tower crane standard section, and the winch is fixedly arranged on the upper part of the winch seat.

[0010] A pulley support frame is arranged on the winch seat, a slewing fixed pulley is arranged on the pulley support frame, and the steel wire rope extended from the winch extends to the lower part of the tower body of the tower crane through the slewing fixed pulley.

[0011] Two groups of lifting units are arranged on the winch seat, and the steel wire ropes of the two groups of lifting units extend along both sides of the tower body of the tower crane to the lift elevator car. The elongation and shortening of the steel wire rope are realized through the winch, so as to realize the up and down movement of the lift elevator car.

[0012] The hook is arranged at the lower end of the steel wire rope.

[0013] The lift elevator car is integrally in a U-shaped state and wraps three sides of the tower body of the tower crane. The lift elevator car includes a transverse box body and longitudinal box bodies arranged on one side of both ends of the transverse box body. A sliding inner door is arranged at the outer end of the longitudinal box body, and an electric extension device is arranged between the sliding inner door and the longitudinal box body to realize the connection of the building seats at different intervals.

[0014] The car top truss is fixedly arranged on the top plate of the longitudinal box body, and the top of the car top truss matches the hook.

[0015] The tower body attached guide rail is arranged at the four corners of the tower body of the tower crane. A slide rail groove is opened on the outer side of the tower body attached guide rail, and an elevator car attached pulley is slidably matched in the slide rail groove, which can ensure that the elevator car attached pulley of the lift elevator car slides up and down in the slide rail groove.

[0016] The elevator car attached pulley is rigidly connected with the inner side wall of the lift elevator car through a connecting rod.

[0017] The steel wire rope connects the hook and the lift elevator car through the car top truss, and the lift elevator car is slidably connected with the tower body attached guide rail through the elevator car attached pulley, so as to realize the up and down movement of the lift elevator car.

[0018] A protection device is arranged around the lift elevator car, which can ensure that the transported materials do not fall down and can also ensure the safety of the operators.

[0019] There are two sliding interior doors installed on the side of the elevator car of the lift that is close to the building. The sliding interior doors achieve the rotation function through pin shafts. When the elevator car of the lift is in the up-and-down movement state, the sliding interior doors are in the closed state. When materials need to be transported, the doors are in the open mode.

[0020] Considering that there may be differences in the spacing between the tower crane tower body and the building block, an electric extension device is installed on the railing at the position of the elevator car door. When materials need to be transported between the elevator car of the lift and the building block, the sliding interior doors are in the open state, and the connection between the elevator car of the lift and the building block in different spacing states can be achieved through the electric extension device.

[0021] The protection device is composed of a protection net and a support frame, and is used to ensure that the transferred materials do not fall downward.

[0022] Taking the tower crane tower body as a material lifting and transferring platform, two sets of lifting units are used to realize the elongation and shortening of the steel wire ropes, and the stable sliding of the elevator car is realized by using the displacement of the elevator car attachment pulley in the tower body attachment guide rail. The sliding interior doors are used for the connection between the elevator car of the lift and the main structure;

[0023] The electric telescopic rod and the electric hook are applied to the operation of the sliding interior doors.

[0024] The cooperation between the slide rail groove and the elevator car attachment pulley enables the elevator car to move smoothly up and down.

[0025] The beneficial effects brought by the technical solution provided by the embodiment of the present utility model are as follows: Aiming at the problems of slow turnover of traditional formwork support materials and high danger coefficient in hoisting, etc., this solution provides a construction material transfer and lifting system. By installing an attachment guide rail on the tower crane tower body and using a winch and an elevator car of the lift, the safe and efficient transfer of construction materials is realized; through the combination of the attachment guide rail and the elevator car, the rapid and safe transfer of materials is realized, and the transfer of the formwork support does not occupy the operation time of the tower crane, realizing the synchronous operation of the formwork support transfer and the hoisting of on-site construction materials; the fully enclosed elevator car design and the protection device can realize the fully enclosed transfer of the formwork support materials, avoid falling objects from height, and improve the operation safety; the electric extension device adapts to different floor spacings, enhancing the flexibility and practicability of the system; the close combination of the U-shaped elevator car and the tower body ensures the stability of the elevator car during the up-and-down movement process;

[0026] It solves the problems of slow turnover of traditional formwork support materials, dangerous hoisting, and occupying the operation time of the tower crane, etc., and is of great significance for improving construction efficiency and ensuring construction safety.
