By incorporating a damping rod, this utility model allows the damping rod to stretch or contract to absorb energy during tower crane swaying, reducing the force transmitted to the building structure and thus reducing the possibility of the building structure connection points being torn.

Description

Technical Field

[0001] This utility model belongs to the technical field of tower crane installation structure, and relates to a stable structure for tower cranes. Background Technology

[0002] Tower cranes, also known as tower hoists, are essential lifting and transportation facilities in modern construction projects, especially high-rise building projects. During tower crane installation, a foundation is first constructed at the base of the tower crane using reinforced concrete. Anchor bolts and other fixing structures are then installed within the foundation to connect the tower crane to the foundation.

[0003] As the tower crane rises, its stability gradually deteriorates. To improve its stability, a wall-mounted rod is installed between the building and the tower crane as a stabilizing structure. However, during the tower crane's swaying, the wall connecting the wall-mounted rod needs to withstand significant tensile or thrust forces, which may cause it to crack. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a stabilizing structure for tower cranes, which effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stabilizing structure for a tower crane, comprising:

[0007] The tower connector includes two slidingly connected first connecting rods and second connecting rods, with the first connecting rods fixedly installed on the tower crane.

[0008] A damping rod is installed between the first connecting rod and the second connecting rod to dampen the sliding of the first connecting rod and the second connecting rod;

[0009] A return spring, which is sleeved on the damping rod;

[0010] Building connector, which is fixedly installed on the building body;

[0011] The first wall-mounted rod is hinged to one end of the second connecting rod;

[0012] The second wall-mounted rod is hinged to the floor connector;

[0013] Adjusting nuts are fixedly connected to the ends of the first and second wall-mounted rods that are close to each other;

[0014] An adjusting screw, the two ends of which are threaded to the adjusting nut, with the threads at the two ends of the adjusting screw rotating in opposite directions.

[0015] Optionally, both the first connecting rod and the second connecting rod are C-shaped channel steel. The first connecting rod has a sliding groove on its side, and the second connecting rod has a sliding strip fixedly connected to its open side. The sliding strip is slidably installed in the sliding groove.

[0016] Optionally, the two ends of the damping rod are respectively hinged to the first connecting rod and the second connecting rod.

[0017] Optionally, a force sensor is provided between the second wall-mounted rod and the floor connector, and the force sensor is connected to an alarm light.

[0018] Optionally, the second wall-mounted rod includes:

[0019] The inner tube has two rectangular through slots along the axial direction, and a barrier bar can be slidably installed at one end of the two rectangular through slots that are close to each other.

[0020] An outer tube, which is slidably fitted onto the inner tube, with the end of the outer tube located between the two blocking bars;

[0021] Two avoidance springs are sleeved on the inner tube. The first ends of the two avoidance springs are respectively fixedly connected to the blocking rod, and the second ends are both fixed to the inner tube.

[0022] In this configuration, the inner tube threaded connection has two adjusting nuts, and the second end of the relief spring abuts against the adjusting nuts respectively.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The tower connector is fixedly connected to the tower crane, and the floor connector is fixedly connected to the floor. The tower connector and the floor connector are connected to the adjusting screw via a first wall-mounted rod, a second wall-mounted rod, and a second adjusting screw. When the tower crane swings, the force is transmitted to the floor. The tower connector is configured with a sliding first connecting rod and a second connecting rod, and is equipped with a damping rod. When the tower crane swings, the damping rod stretches or contracts to absorb energy, reducing the force transmitted to the floor and thus reducing the possibility of the floor connection point being torn.

[0025] 2. By installing force sensors, the force transmitted from the tower crane to the building is monitored. When the force reaches the set value, an alarm light is activated to facilitate timely handling.

[0026] 3. By setting up sliding connections between the inner and outer tubes, the length of the second wall-mounted rod can change with the swaying of the tower crane. Avoidance springs and blocking bars are set on both sides of the end of the outer tube. When the outer tube slides, it pushes any blocking bar to compress the corresponding avoidance spring. By setting the elastic force of the avoidance spring, the avoidance spring does not exceed the bearing limit of the wall within a certain compression distance, so that the tower crane has a certain swaying space and reduces the impact on the wall.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 and Figure 2 This utility model discloses a stabilizing structure for a tower crane, comprising a tower connector 1 and a floor connector 4. The tower connector 1 includes two mutually slidingly connected first connecting rods 11 and second connecting rods 12. The first connecting rods 11 are fixedly installed on the tower crane. A damping rod 2 is installed between the first connecting rods 11 and second connecting rods 12, damping the sliding of the first connecting rods 11 and second connecting rods 12. A return spring 3 is sleeved on the outer side of the damping rod 2. The floor connector 4 is fixedly installed on the floor. One end of the second connecting rod 12 is hinged to a first wall-mounted rod 5, and the floor connector 4 is hinged to a second wall-mounted rod 6. The ends of the first wall-mounted rod 5 and the second wall-mounted rod 6 that are close to each other are fixedly connected to an adjusting nut 71. The adjusting nut 71 is threadedly connected to the same adjusting screw 72, and the two ends of the adjusting screw 72 have opposite thread directions.

[0035] Specifically, tower connector 1 is fixedly connected to the tower crane, and floor connector 4 is fixedly connected to the floor. Tower connector 1 and floor connector 4 are connected to adjusting screw 72 via first wall-mounted rod 5 and second wall-mounted rod 6. When the tower crane swings, the force is transmitted to the floor. Tower connector 1 is configured with a sliding first connecting rod 11 and second connecting rod 12, and a damping rod 2 is provided. When the tower crane swings, the damping rod 2 stretches or contracts to absorb energy, reducing the force transmitted to the floor and thus reducing the possibility of the floor connection being torn.

[0036] In some feasible embodiments, the first connecting rod 11 and the second connecting rod 12 can be configured as rectangular rods. The first connecting rod 11 is fixedly connected to the tower crane by bolts. The first connecting rod 11 and the damping rod 2 are sleeved inside the second connecting rod 12. The damping rod 2 is located outside the first connecting rod 11, and its two ends are connected to the first connecting rod 11 and the second connecting rod 12 respectively. Both ends of the first connecting rod 11 pass through the second connecting rod 12. Both ends of the first connecting rod 11 are provided with connecting plates to connect the first wall-mounted rod 5. The damping rod 2 is horizontal to the ground. Two tower connectors 1 are installed on both sides of the tower crane. The two ends of the tower connectors 1 are located at the four top corners of the tower crane to adapt to different wall-mounted rod installation structures such as three-bar and four-bar. Each set of the first wall-mounted rod 5, the second wall-mounted rod 6 and the adjusting screw 72 is one of the three-bar or four-bar types.

[0037] The first connecting rod 11 and the second connecting rod 12 are cylindrical or rectangular rods. By setting the adjusting screw 72 and the adjusting nut 71, the distance between the first connecting rod 11 and the second connecting rod 12 can be easily adjusted to adapt to different installation distances of tower cranes and buildings.

[0038] The floor connector 4 can be set according to the actual installation location. In this embodiment, it is installed on the wall. The floor connector 4 includes two rectangular plates. Fixing bolts are provided at the top corners of the two rectangular plates. The rectangular plates are located on both sides of the wall and are fixed by the fixing bolts.

[0039] As one specific embodiment of the stabilizing structure for a tower crane provided in the application, please refer to [link / reference needed]. Figure 3 Both the first connecting rod 11 and the second connecting rod 12 are C-shaped channel steel. The first connecting rod 11 has a sliding groove 13 on its side, and the second connecting rod 12 has a sliding strip 14 fixedly connected to its open side. The sliding strip 14 is slidably installed in the sliding groove 13.

[0040] Overall, by setting the sliding groove 13 and the sliding strip 14 together, the sliding trajectory of the second connecting rod 12 is standardized, and the positions of the first connecting rod 11 and the second connecting rod 12 are relatively fixed in the direction perpendicular to the sliding direction.

[0041] In some feasible embodiments, two rectangular bars are fixedly connected to both sides of the first connecting rod 11, forming a sliding groove 13 between the rectangular bars. The sliding bar 14 is C-shaped and adapted to the sliding groove 13. To facilitate the movement of the damping rod 2, the damping rod 2 is hinged to both the first connecting rod 11 and the second connecting rod 12.

[0042] As another specific implementation of the stabilizing structure of the tower crane provided in the application, a force sensor 61 is installed between the second wall-mounted rod 6 and the floor connector 4, and the force sensor 61 is connected to an alarm light.

[0043] Based on specific usage scenarios, force sensor 61 is set up to monitor the force transmitted from the tower crane to the building. When the force reaches the set value, an alarm light will be activated to facilitate timely handling.

[0044] In some feasible approaches, the alarm light can be an audible and visual alarm light.

[0045] Further, please refer to Figure 4 and Figure 5 The second wall-mounted rod 6 includes an inner tube 62, which has two rectangular through slots 621 along the axial direction. A barrier rod 622 is slidably installed at one end of the two rectangular through slots 621 that are close to each other. An outer tube 63 is slidably sleeved on the outside of the inner tube 62, with the end of the outer tube 63 located between the two barrier rods 622. Two clearance springs 64 are sleeved on the inner tube 62. The first end of each clearance spring 64 is fixedly connected to the barrier rod 622, and the second end is fixed to the inner tube 62.

[0046] It should be understood that by setting the inner tube 62 and outer tube 63 with sliding connection, the length of the second wall-mounted rod 6 can change with the swaying of the tower crane. The outer tube 63 is provided with relief springs 64 and blocking rods 622 on both sides of the end. When the outer tube 63 slides, it pushes any blocking rod 622 to compress the corresponding relief spring 64. By setting the elastic force of the relief spring 64, the relief spring 64 does not exceed the bearing limit of the wall within a certain compression distance, so that the tower crane has a certain swaying space and reduces the impact on the wall.

[0047] Furthermore, the inner tube 62 is threadedly connected to two adjusting nuts 65, and the second end of the relief spring 64 abuts against the adjusting nuts 65 respectively.

[0048] It should be understood that by setting the adjusting nut 65, the initial elastic force of the avoidance spring 64 can be easily adjusted. This elastic force should be adjusted according to the actual situation so that the tower crane can be supported under normal conditions to maintain the stability of the tower crane. In extreme weather conditions where the tower crane is subjected to greater forces, it should provide a certain amount of movement space for the tower crane and reduce direct impact on the building connection points.

[0049] Meanwhile, the stabilizing structure is set in multiple layers according to the different heights of the tower crane. By setting the avoidance spring 64, the situation where one of the stabilizing structures is subjected to greater force due to installation errors can also be reduced. By compressing the avoidance spring 64, each stabilizing structure can provide support for the tower crane.

[0050] In some feasible configurations, both the inner tube 62 and the outer tube 63 are cylindrical rods. The inner tube 62 has a rectangular through-slot 621 axially formed on its side. The barrier rod 622 is a rectangular block, with both ends protruding from the sides of the inner tube 62. A sealing plate is fixedly connected to the end of the outer tube 63 via a bolt array. The sealing plate is fitted onto the inner tube 62 and positioned between the two barrier rods 622. To facilitate the installation of components such as the avoidance spring 64, there is a certain space between the outer side of the inner tube 62 and the inner side of the outer tube 63. By setting the sealing plate, the inner side of the sealing plate can fit against the outer side of the inner tube 62, thereby reducing swaying. Simultaneously, a cylindrical block that fits against the inner side of the outer tube 63 can be fixedly installed at the end of the inner tube 62. The thickness of the sealing plate is slightly less than the distance between the two rectangular through-slots 621, and both sides of the sealing plate fit against the barrier rods 622.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
