Abstract
Description
Technical Field
[0001] The present invention relates to the field of construction, and particularly to a tower crane with a wind-resistant structure and its working method. Background Art
[0002] Tower cranes are machines used to build tower buildings in construction projects. The terrain environment in construction sites is mostly open on all sides, so the wind flow and air currents blow back and forth without obstruction, and the wind volume is often large. The wind force will directly act on the tower crane. Therefore, the tower crane needs to have good wind resistance to ensure the safety of tower buildings and construction workers.
[0003] The invention patent with the Chinese patent application number 202110833953.6 discloses a boom tower crane wind protection method, which is carried out in cooperation with a boom tower crane wind protection device. The boom tower crane wind protection device includes a foundation, on which a plurality of standard sections vertically arranged and fixedly connected to each other are provided. There is a support control mechanism between the standard section directly connected to the foundation and the foundation. Above the support control mechanism of the standard section, eight groups of four support rods perpendicular to each other are provided. Each group of support rods is provided with a detection housing, and each detection housing is internally provided with a touch detection mechanism. A wind speed detector is provided on the topmost standard section. Two connecting and fixing rods are symmetrically provided on the topmost standard section, and a counterweight level control system is provided for the connecting and fixing rods. Four slide pipes are symmetrically provided inside the standard section, and a moving fixing mechanism is provided on each slide pipe. The purpose of comprehensive wind resistance and anti-wind of the boom tower crane is realized without changing the original structure and load of the tower crane and without occupying the internal passage space of the tower crane standard section. The technical solution proposed by the above invention strengthens the connection between the foundation and the standard section by setting a support control mechanism. However, through the analysis of the wind force on the overall tower crane, the force is mainly concentrated in the middle and upper middle parts. Even if the bottom is well reinforced, there may still be excessive force in the middle, resulting in deformation or breakage, affecting the safety of the building and personnel. Summary of the Invention
[0004] Therefore, in view of the above problems, the present invention proposes a tower crane with a wind-resistant structure and its working method, which solves the technical problem that the middle and upper middle parts of the existing tower crane are prone to deformation and even breakage under the action of strong wind during the working process due to its structural design.
[0005] To achieve the above object, the present invention adopts the following technical solutions: A tower crane with a wind-resistant structure, including an annular support chassis, and a plurality of support uprights fixedly arranged on the annular support chassis. A plurality of mounting holes are arranged around the annular support chassis, and the circumferential distance between adjacent two mounting holes is the same. The support uprights are inserted into the mounting holes, and a first wind-resistant and stability-maintaining device for fixing the support uprights is arranged on the annular support chassis. A second wind-resistant and stability-maintaining device is movably arranged between adjacent two support uprights. The first wind-resistant and stability-maintaining device includes an arc-shaped connecting plate and a first telescopic block and a second telescopic block arranged at both ends of the arc-shaped connecting plate. The arc-shaped connecting plate is used to connect the bottoms of adjacent two support uprights to cause them to generate linkage. The first telescopic block and the second telescopic block are respectively abutted and connected with adjacent two support uprights;
[0006] A working platform for construction is sleeved on the support upright.
[0007] Further, a first extension plate and a second extension plate are arranged on the annular support chassis. The first extension plate extends along the inner side of the annular support chassis in the horizontal plane, and the second extension plate extends along the outer side of the annular support chassis in the horizontal plane.
[0008] Further, a first automatic locking nail is arranged on the lower bottom surface of the first extension plate, and a second automatic locking nail is arranged on the lower bottom surface of the second extension plate. A rotation motor for driving its own rotation is integrally arranged inside both the first automatic locking nail and the second automatic locking nail.
[0009] Further, the radian of the arc-shaped connecting plate fits the radian of the annular support chassis and the arc-shaped connecting plate is fixedly connected with the annular support chassis. A function cavity is arranged inside the arc-shaped connecting plate. The first telescopic block and the second telescopic block are arranged in the function cavity and are rotatably connected with the arc-shaped connecting plate.
[0010] Further, the first telescopic block and the second telescopic block are of a symmetric structure, and both are of a triangular prism structure. A first connection hole is arranged on the side surface of the first telescopic block close to the second telescopic block, and a second connection hole is arranged on the side surface of the second telescopic block close to the first telescopic block. A hydraulic telescopic push rod is arranged between the first telescopic block and the second telescopic block in the function cavity. Both ends of the hydraulic telescopic push rod are respectively inserted into the first connection hole and the second connection hole. By controlling the telescopic of the hydraulic telescopic push rod, the telescopic of the first telescopic block and the second telescopic block is controlled. By default, in the initial state, the hydraulic telescopic push rod pushes both the first telescopic block and the second telescopic block outwards to abut against the support upright.
[0011] Further, the second wind resistance and stability device includes a first connecting plate, a second connecting plate, and wind resistance connecting rods disposed between the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate are respectively fixedly disposed at the left and right ends of the middle part of the support vertical frame, and the wind resistance connecting rods are respectively movably connected to the first connecting plate and the second connecting plate.
[0012] Further, the first connecting plate and the second connecting plate are in the same horizontal plane, and both extend vertically up and down. The top extends to the upper middle part of the support vertical frame, and the bottom extends to the lower middle part of the support vertical frame. A number of first clamping holes are provided on the first connecting plate, and a number of second clamping holes are provided on the second connecting plate. The horizontal positions of the first clamping holes and the second clamping holes correspond one by one. One end of the wind resistance connecting rod is clamped with the first clamping hole, and the other end is clamped with the second clamping hole.

The first movable telescopic rod body and the second movable telescopic rod body are both inserted into the central rod body. A high-elasticity spring is disposed between the first movable telescopic rod body and the second movable telescopic rod body. The first movable telescopic rod body and the second movable telescopic rod body perform elastic displacement along the axial direction of the central rod body under the action of the high-elasticity spring. In the initial state, when the wind resistance connecting rod is placed between the first connecting plate and the second connecting plate, the high-elasticity spring is in a stressed state, and the first movable telescopic rod body and the second movable telescopic rod body are subjected to the elastic force of the high-elasticity spring and thus generate a top thrust on the support vertical frame.
[0014] Further, sliding balls are provided at the free end ends of the first movable telescopic rod body and the second movable telescopic rod body.
[0015] A working method of a tower crane with a wind resistance structure includes the following steps:
[0016] S1. Foundation pit treatment: Driving piles, lowering the groundwater level of the foundation pit to 500 mm below the base, excavating with a slope and controlling the base elevation, pouring a plain concrete cushion, and laying a fine sand sliding layer;
[0017] S2. Placing the annular support chassis: Using a crane to place the annular support chassis on the foundation pit. At this time, the first automatic locking nails and the second automatic locking nails are inserted into the ground and start to rotate automatically, improving the cooperation with the ground;
[0018] S3. Installing the first wind resistance and stability device: Fixing and installing the arc-shaped connecting plate on the annular support chassis and strengthening the connection with bolts;
[0019] S4. Place and reinforce the support upright frame; insert the support upright frame into the mounting holes on the annular support chassis through a crane in sequence. During the installation process, the first telescopic block and the second telescopic block on the arc-shaped connecting plate remain retracted. After the support upright frame is completely inserted into the mounting hole, remove the external force to make the first telescopic block and the second telescopic block protrude outward until they abut against the support upright frame, providing strong elastic support for the bottom area of the support upright frame.
[0020] S5. Install the working platform; sleuth the working platform over the support upright frame from top to bottom through a crane, and at the same time install a hydraulic lifting system on the working platform for control through the hydraulic lifting system.
[0021] S6. Install the second wind resistance and stability device; erect the wind resistance connecting rod between the first clamping hole and the second clamping hole to ensure that the wind resistance connecting rod remains horizontal after installation. In the initial state, both the first movable telescopic rod body and the second movable telescopic rod body on the wind resistance connecting rod are in the state of protruding outward.
[0022] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:
[0023] 1. The wind-resistant tower crane proposed by the present invention, compared with the existing tower cranes, can cope with the influence brought by stronger airflows, and at the same time can flexibly respond when facing strong winds through the improvement of its own structure. Specifically, by setting the first wind resistance and stability device and the second wind resistance and stability device to cooperate with each other, to ensure good support for the bottom and the upper-middle area of the support upright frame in the tower crane. At the same time, both of them innovatively adopt elastic support to avoid mechanical structure deformation caused by rigid support; and the present invention strengthens the support for the annular support chassis synchronously to improve the stability of the annular support chassis. By setting the first extension plate and the second extension plate on the annular support chassis, to increase the contact area between the annular support chassis and the ground. At the same time, a first automatic locking nail is provided on the bottom surface of the first extension plate, and a second automatic locking nail is provided on the bottom surface of the second extension plate. Both the first automatic locking nail and the second automatic locking nail work through a rotating motor, and they increase the cooperation degree with the ground through self-rotation, ensuring that the annular support chassis can be firmly combined with the ground without shaking.
[0024] 2. The arc-shaped connecting plate in the present invention is arranged between two adjacent supporting vertical frames. Its main function is to connect the two adjacent supporting vertical frames, enabling them to establish a linkage. In traditional tower cranes, the supporting frames are all independently supported without any reliance around them. However, in the present invention, an arc-shaped connecting plate is fixedly arranged between the two supporting vertical frames. A first telescopic block and a second telescopic block are correspondingly arranged on both sides of the arc-shaped connecting plate. The first telescopic block and the second telescopic block are both rotatably connected to the arc-shaped connecting plate and are linked through a hydraulic telescopic push rod, ensuring that both the first telescopic block and the second telescopic block abut against the supporting vertical frame. When a strong wind comes, the supporting vertical frame sways with the strong wind. The force at the top of the supporting vertical frame is transmitted to the bottom, and the bottom will swing slightly. The arc-shaped connecting plate coordinates the bottoms of each supporting vertical frame to form a whole, and together with the annular supporting bottom frame, it ensures the stability of the bottom of the supporting vertical frame. When the bottom of the supporting vertical frame deflects, the first telescopic block and the second telescopic block on both sides thereof always abut against both sides of the supporting vertical frame to provide elastic support for it.
[0025] 3. For the middle and upper parts of the tower crane, when affected by strong winds, compared with the bottom, it usually swings to a greater extent. During the swinging process, the isolated supporting vertical frames are prone to break during the shaking and then cause a chain reaction, possibly resulting in the risk of overall collapse. In the present invention, the second wind resistance and stability device is directly used to carry out the stability maintenance work for the middle and upper parts of the tower crane. It also adopts the method of establishing connections between each supporting vertical frame to make them linked. In the face of strong winds, it is equivalent to using the wind resistance connecting rods to support each supporting vertical frame to provide stability maintenance operations. When two supporting vertical frames swing in a posture of approaching each other, the wind resistance connecting rods provide an outward pushing force for them so that they will not deflect too much or even interfere with each other. When two supporting vertical frames swing in a posture of moving away from each other, the wind resistance connecting rods on the other side also provide a pushing force to ensure that their swinging range will not be too large. At the same time, the supporting performance of the wind resistance connecting rods is also elastic support, which not only ensures that the supporting vertical frames will not be deformed due to hard support during the shaking process, but also ensures the working stability of the wind resistance connecting rods themselves.
[0026] 4. At the same time, in the present invention, sliding balls are provided at the free ends of the first and second movable telescopic rod bodies. The purpose is to ensure that when each support stand sways in the wind, the states of each support stand are different. Even if the wind direction is the same, the movement trajectories of the independent support stands will all change slightly. Through the setting of the sliding balls, it is ensured that even if there are slight changes in the movement trajectories between adjacent support stands, the wind resistance connecting rods always abut against the support stands and can deflect to a certain extent under the action of the sliding balls, that is, form a small angle with the horizontal plane. This is to ensure that the support provided for the support stand is always elastic support, avoiding deformation of the support member and the support stand caused by rigid support, and also avoiding rigid interference between the support member and the support stand.
