Description

Technical Field

[0001] This utility model relates to the field of tower crane base technology, specifically a new type of wind-resistant and earthquake-resistant tower crane base for building tower cranes. Background Technology

[0002] Tower cranes are the most commonly used lifting equipment on construction sites. They are constructed by connecting sections together, resembling an iron tower, and are also called tower cranes. They are used to lift construction materials such as steel bars, timber, and scaffolding pipes. Tower cranes are present in almost all construction sites and are indispensable equipment. To ensure the stable support and operation of the tower crane, a base structure is usually installed at the bottom of the tower crane to enhance the support and ensure the stable installation of the tower crane.

[0003] In the current technology, when installing tower cranes, in order to make the tower crane more stable, most construction companies will pour a concrete platform on the bottom of the tower crane to improve the seismic performance of the tower crane base. However, pouring a large amount of concrete at the bottom of the base not only wastes building materials, but also increases the workload during the dismantling of the tower crane. Utility Model Content

[0004] The purpose of this invention is to provide a novel wind-resistant and earthquake-resistant tower crane base for building tower cranes, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is implemented through the following technical solution: This utility model relates to a novel wind- and earthquake-resistant tower crane base for building tower cranes, comprising a main tower crane support, several stabilizing supports (first type) fixedly connected to the middle of the main tower crane support, several stabilizing supports (second type) fixedly connected to the middle of the main tower crane support, climbing components fixedly connected to the stabilizing supports (second type), and further including: The base section, located at the bottom of the tower crane's main support, is used to install and fix the tower crane body; and The stabilizing section is installed in the middle of the main support of the tower crane, and the base section is installed directly above the base section. The stabilizing section is used to support the bottom of the tower crane and improve the stability of the tower crane. The stabilizing section works in conjunction with the base section to adjust the distance between the bottom support points of the stabilizing section, thereby adjusting the stability performance of the tower crane.

[0006] Furthermore, the base portion includes: Fasteners are installed at the bottom of the tower crane main support and are used to install and fix several tower crane main supports. The foundation component is located directly below the fixing component and is used to improve the seismic performance of the tower crane base.

[0007] Furthermore, the fasteners include a fixing base disposed at the bottom of the main support of the tower crane; The bottom side wall of the tower crane main support is fixedly connected with fastening blocks, which are fixedly connected to the top of the fixed base by bolts. Several connecting plates are fixedly connected to the bottom of the fixed base.

[0008] Furthermore, the foundation components include cast-in-place concrete piles positioned directly beneath the connecting plate. The internal fixed connection of the cast cement pile has several fixed steel bars, the top of which is threaded and passes through the inside of the connecting plate; The top of the fixed reinforcing bar is rotatably connected with a fastening nut, and a stabilizing steel plate is set at the bottom of the poured cement pile, with the fixed reinforcing bar passing through the stabilizing steel plate.

[0009] Furthermore, the stabilizing department includes: Auxiliary components are installed inside the cast-in-place concrete piles and are used to stabilize the main support of the tower crane. Adjusting components are installed on the side wall of the main support of the tower crane and are used to adjust the position of auxiliary components.

[0010] Furthermore, the auxiliary components include several sliding columns that are slidably connected inside the fixed base; Among them, a fixed block is fixedly connected to the top of the end of the sliding column away from the fixed base, and a hydraulic support rod is rotatably connected to the fixed block. The hydraulic support rod is used to assist in supporting the main support of the tower crane.

[0011] Furthermore, the adjusting component includes several hydraulic push rods fixedly connected inside the fixed base. One end of the hydraulic push rod away from the inner wall of the fixed base is fixedly connected to the sliding column. The hydraulic push rod is used to push the sliding column to slide inside the fixed base. Among them, several connecting blocks are fixedly connected to the middle side wall of the tower crane main support. Limiting rods are fixedly connected to the connecting blocks. Support sleeves are slidably connected to the bottom of the limiting rods. The end of the hydraulic support rod away from the fixed block is rotatably connected to the side wall of the support sleeve. A compression spring is sleeved on the end of the limiting rod away from the support sleeve.

[0012] This utility model has the following beneficial effects: (1) In this utility model, when using the tower crane base, firstly, by setting up the base, before installing the tower crane, it is necessary to pour concrete piles at the bottom of the tower crane installation. First, excavate the foundation pit at the bottom of the base and then put the stabilizing steel plate into the bottom of the foundation pit. At this time, backfill the foundation pit and reserve the pouring space for the concrete piles. Fix the reinforcing bars through the stabilizing steel plate. After the concrete piles are poured, fix the base to the top of several fixing reinforcing bars with bolts. Finally, fix the tower crane to the top of the fixed base. This setting is conducive to improving the stability of the tower crane while reducing the pouring of concrete. In addition, by setting the stabilizing steel plate at the bottom of the concrete piles, the stabilizing steel plates through the stabilizing steel plate are conducive to fixing the position of several concrete piles, thereby ensuring the integrity between several concrete piles. (2) In this utility model, by setting up a stabilizing part, the tower crane is raised multiple times according to the progress of the project during the installation process. During the process of raising the tower crane, as the height of the tower crane continues to increase, the wind resistance of the tower crane also increases. At this time, by activating the hydraulic push rod, one end of the hydraulic push rod pushes the sliding column to slide outward along the sliding column. At the same time, the hydraulic support rod is activated, and the support point between the hydraulic support rod and the sliding column continuously expands outward under the drive of the hydraulic push rod. This setting is conducive to increasing the distance between the support points of several sliding columns and the hydraulic support rod to enhance the stability support of the stabilizing part for the tower crane. When the support sleeve of the hydraulic support rod away from the fixed block is squeezed upward along the limit rod to compress the spring, this setting is conducive to increasing the vertical height between the hydraulic support rod and the tower crane, thereby enhancing the wind resistance performance of the tower crane by increasing the support point of the hydraulic support rod for the tower crane.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1, please refer to Figures 1-4 As shown, this utility model relates to a novel wind- and earthquake-resistant tower crane base for building tower cranes, comprising a main tower crane support 1, several stabilizing supports 11 fixedly connected to the middle of the main tower crane support 1, several stabilizing supports 22 fixedly connected to the middle of the main tower crane support 1, climbing components 13 fixedly connected to the stabilizing supports 22, and further including: Base section 2, located at the bottom of the tower crane main support 1, is used to install and fix the tower crane body; and The stabilizing part 3 is installed in the middle of the main support 1 of the tower crane, and the base part 2 is installed directly above the base part 2. The stabilizing part 3 is used to support the bottom of the tower crane and improve the stability of the tower crane. The stabilizing part 3, in conjunction with the base part 2, adjusts the distance between the bottom support points of the stabilizing part 3, thereby adjusting the stability performance of the tower crane.

[0024] The base portion 2 includes: Fixing member 21 is provided at the bottom of the tower crane main support 1 and is used to install and fix several tower crane main supports 1. The foundation component 22 is located directly below the fixing component 21 and is used to improve the seismic performance of the tower crane base.

[0025] The fastener 21 includes a fixed base 211 disposed at the bottom of the main support 1 of the tower crane; Among them, the bottom side wall of the tower crane main support 1 is fixedly connected with a fastening block 212, which is fixedly connected to the top of the fixed base 211 by bolts. Several connecting plates 213 are fixedly connected to the bottom of the fixed base 211.

[0026] Foundation component 22 includes cast-in-place cement piles 221 disposed directly below the connecting plate 213. The concrete pile 221 is internally fixed with several fixing steel bars 222. The top of the fixing steel bars 222 is threaded and the fixing steel bars 222 pass through the inside of the connecting plate 213. The top of the fixing reinforcing bar 222 is rotatably connected to a fastening nut 223, and a stabilizing steel plate 224 is provided at the bottom of the cast-in-place cement pile 221. The fixing reinforcing bar 222 passes through the stabilizing steel plate 224. The function of this component is that when using the tower crane base, firstly, by setting up the base part 2, before installing the tower crane, it is necessary to cast the cast-in-place cement pile 221 at the bottom of the tower crane installation. First, a foundation pit is excavated at the bottom of the base, and then the stabilizing steel plate 224 is placed at the bottom of the foundation pit. At this time, the foundation pit is backfilled and space is reserved for casting the cement pile 221. The fixing reinforcing bar 222 is fixedly inserted through the stabilizing steel plate. Directly above 224, after the concrete pile 221 is poured, the fixed base 211 is fixedly connected to the top of several fixed reinforcing bars 222 by bolts. Finally, the tower crane is fixedly connected to the top of the fixed base 211. This arrangement helps to improve the stability of the tower crane while reducing the amount of concrete poured. In addition, by setting a stabilizing steel plate 224 at the bottom of the concrete pile 221, the fixed reinforcing bars 222 can pass through the stabilizing steel plate 224, which helps to fix the position of several concrete piles 221, thereby ensuring the integrity of several concrete piles 221.

[0027] Example 2 differs from Example 1 in that: Figures 1-6 As shown, the stabilizing unit 3 includes: Auxiliary component 31 is installed inside the cast cement pile 221 and is used to stabilize the main support 1 of the tower crane. Adjusting component 32 is installed on the side wall of the tower crane main support 1 and is used to adjust the position of auxiliary component 31.

[0028] The auxiliary component 31 includes a plurality of sliding columns 311 that are slidably connected inside the fixed base 211; Among them, a fixed block 312 is fixedly connected to the top of the end of the sliding column 311 away from the fixed base 211, and a hydraulic support rod 313 is rotatably connected to the fixed block 312. The hydraulic support rod 313 is used to assist in supporting the main support frame 1 of the tower crane.

[0029] The adjusting component 32 includes a plurality of hydraulic push rods 321 fixedly connected inside the fixed base 211. One end of the hydraulic push rod 321 away from the inner wall of the fixed base 211 is fixedly connected to the sliding column 311. The hydraulic push rod 321 is used to push the sliding column 311 to slide inside the fixed base 211. The main support frame 1 of the tower crane has several connecting blocks 322 fixedly connected to its middle side wall. Limiting rods 323 are fixedly connected to the connecting blocks 322, and a support sleeve 324 is slidably connected to the bottom of the limiting rods 323. One end of a hydraulic support rod 313 away from the fixed block 312 is rotatably connected to the side wall of the support sleeve 324. A compression spring 325 is fitted onto the end of the limiting rod 323 away from the support sleeve 324. The function of this component is to stabilize the tower crane by setting up the stabilizing part 3. During the installation process, the tower crane is raised multiple times according to the project progress. As the tower crane's height increases, the wind resistance it experiences also increases. At this time, the hydraulic push rod 321 is activated, and one end of the hydraulic push rod 321 pushes the sliding column 3. 11 slides outward along the sliding column 311, while the hydraulic support rod 313 is activated. The support point between the hydraulic support rod 313 and the sliding column 311 expands outward continuously under the drive of the hydraulic push rod 321. This arrangement is beneficial to increase the distance between the fulcrum points of several sliding columns 311 and the hydraulic support rod 313 to enhance the stable support of the stabilizing part 3 for the tower crane. When the support sleeve 324 of the hydraulic support rod 313 away from the fixed block 312 presses the compression spring 325 upward along the limit rod 323, this arrangement is beneficial to increase the vertical height between the hydraulic support rod 313 and the tower crane, thereby enhancing the wind resistance performance of the tower crane by increasing the support point of the hydraulic support rod 313 for the tower crane.

[0030] One specific application of this embodiment is: When using this tower crane base, firstly, by setting up the base part 2, before installing the tower crane, it is necessary to pour concrete piles 221 at the bottom of the tower crane installation. First, a foundation pit is excavated at the bottom of the base, and then the stabilizing steel plate 224 is placed at the bottom of the foundation pit. At this time, the foundation pit is backfilled and space is reserved for pouring the concrete piles 221. The fixing steel bars 222 are fixedly inserted through the top of the stabilizing steel plate 224. After the concrete piles 221 are poured, the fixed base 211 is fixedly connected to the top of several fixing steel bars 222 by bolts. Finally, the tower crane is fixedly connected to the top of the fixed base 211. This setting is beneficial to improving the stability of the tower crane while reducing the amount of concrete pouring. In addition, by setting the stabilizing steel plate 224 at the bottom of the concrete piles 221, the fixing steel bars 222 are inserted through the stabilizing steel plate 224, which is beneficial to fixing the position of several concrete piles 221, thereby ensuring that several concrete piles 221 maintain integrity. By setting up the stabilizing unit 3, the tower crane is raised multiple times during the installation process according to the project progress. As the tower crane is raised, the wind resistance it experiences increases. At this time, the hydraulic push rod 321 is activated. One end of the hydraulic push rod 321 pushes the sliding column 311 to slide outward along the sliding column 311. At the same time, the hydraulic support rod 313 is activated. The support point between the hydraulic support rod 313 and the sliding column 311 expands outward under the drive of the hydraulic push rod 321. This setting helps to increase the distance between the fulcrum points of several sliding columns 311 and the hydraulic support rod 313, thereby enhancing the stability support of the stabilizing unit 3 for the tower crane. When the support sleeve 324 of the hydraulic support rod 313 away from the fixed block 312 presses the compression spring 325 upward along the limit rod 323, this setting helps to increase the vertical height between the hydraulic support rod 313 and the tower crane, thereby enhancing the wind resistance of the tower crane by increasing the support point of the hydraulic support rod 313 for the tower crane.
