Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to an adaptive internal climbing tower crane. Background Technology

[0002] Internal climbing tower cranes are often used in the construction of super high-rise buildings because they are located inside the building structure, have low requirements for the working range, and the tower crane boom can be shortened as much as possible without occupying the external space of the building structure. They can climb upward using the building structure, and the climbing height is not limited. The tower body is generally of free height. The overall structure is lightweight and has little impact on the facade.

[0003] Before installation, commonly used internal climbing tower cranes require pre-embedded parts in the main structure to support the crane. This not only makes operation inconvenient and poses higher safety risks, but also affects the working efficiency of the internal climbing tower crane. In addition, since internal climbing tower cranes are often installed in building shafts, more pre-embedded issues need to be considered for shafts with only structural beams on one or both sides, making them unsuitable for more complex shafts in terms of adaptability and convenience. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of the prior art by disclosing an adaptive internal climbing tower crane. Through the structural design of this internal climbing tower crane, it is made suitable for main structure construction projects with complex shaft structures.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] An adaptive internal climbing tower crane, the internal climbing tower crane including a main structure and a lifting mechanism, the main structure being disposed on the top side of the lifting mechanism;

[0007] The lifting mechanism includes a first lifting layer and a second lifting layer. The second lifting layer is disposed at the top of the first lifting layer. The first and second lifting layers are telescopic structures. When the first and second lifting layers are in a retracted state, the two lifting layers are each one standard section length. When the first and second lifting layers are in an extended state, the two lifting layers are each two standard section lengths.

[0008] The bottom of the first lifting layer is provided with a bottom support steel beam, the middle support steel beam is provided between the first lifting layer and the second lifting layer, and the top support steel beam is provided at the top of the second lifting layer. Each support steel beam is selectively connected and fixed to the building structure support point, and the main structure is set on the top support steel beam.

[0009] The first and second lifting layers are each equipped with a hydraulic system. The hydraulic system in the first lifting layer is connected at both ends to the bottom support beam and the middle support beam, respectively. The bottom end of the hydraulic system in the second lifting layer is located on the middle support beam.

[0010] The lifting mechanism is driven by the hydraulic system within the first and second lifting layers to reciprocate and extend, thereby driving the main structure to climb.

[0011] According to a preferred embodiment, the initial stage of the lifting mechanism is as follows: the first lifting layer is in a retracted state, and the second lifting layer is in an extended state;

[0012] When the lifting mechanism begins to climb, the bottom and top support beams are fixed to the side support structures respectively; the middle support beams are disconnected from the side support structures, the first lifting layer extends and drives the middle support beams upward, until the first lifting layer extends to the length of two standard sections, and the second lifting layer contracts to the length of one standard section.

[0013] Then the middle layer support steel beam is fixedly supported by the two side support structures, the bottom layer support steel beam is disconnected from the two side support structures, the first lifting layer is shortened to the length of a standard section, at this time the bottom layer support steel beam is lifted by a standard section, and then the bottom layer support steel beam is fixedly connected to the two side support structures.

[0014] Disconnect the top-level support steel beam from the support structures on both sides. The second lifting layer is extended by the hydraulic system until it is extended into two standard sections. The connection between the top-level support steel beam and the support structures on both sides is completed, thereby driving the main structure to climb one standard section. At this time, the lifting mechanism returns to the initial stage state.

[0015] According to a preferred embodiment, the first and second lifting layers are laterally provided with a pulley system, wherein each pulley in the pulley system makes rolling contact with the sidewall of the surrounding supporting structure.

[0016] According to a preferred embodiment, each layer of supporting steel beams includes: a steel beam frame, wall support arms, and structural beam support arms. The wall support arms and structural beam support arms are respectively disposed on both sides of the steel beam frame and are capable of extension and retraction to complete the connection and fixation or disconnection with the corresponding supporting structure; each lifting layer is rigidly connected to the steel beam frame.

[0017] According to a preferred embodiment, the end of the wall support arm is a circular pad, which is used to generate frictional force by contacting the supporting building wall.

[0018] According to a preferred embodiment, the end of the structural beam support arm is an "L-shaped" bayonet structure, which can cooperate with the structural beam supporting the building to obtain an upward supporting force.

[0019] According to a preferred embodiment, the wall support arm is also equipped with a hydraulic servo system.

[0020] When it is necessary to fix the tower crane, the wall support arm extends and contacts the wall structure. If the interaction force is lower than the critical value, the hydraulic system continues to pressurize so that the friction force at the wall meets the condition of supporting the self-weight of the tower crane.

[0021] According to a preferred embodiment, the first lifting layer contains a bottom hydraulic system, which includes four hydraulic jacks, respectively arranged around the first lifting layer.

[0022] According to a preferred embodiment, the second lifting layer contains a top-level hydraulic system, which includes eight hydraulic jacks evenly distributed around the second lifting layer.

[0023] According to a preferred embodiment, each hydraulic jack is rigidly connected to the supporting steel beam.

[0024] The aforementioned main solution of the present invention and its various further alternative solutions can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed by the present invention. Those skilled in the art, after understanding the solution of the present invention, will realize that there are many combinations based on existing technology and common knowledge, all of which are technical solutions to be protected by the present invention, and will not be exhaustively listed here.

[0041] Example 1

[0042] refer to Figure 1 As shown in the figure, an adaptive internal climbing tower crane is illustrated. The internal climbing tower crane includes a main structure and a lifting mechanism. The main structure is located on the top side of the lifting mechanism and includes a lifting device.

[0043] Preferably, the lifting mechanism includes: a first lifting layer 2 and a second lifting layer 7, wherein the second lifting layer 7 is disposed at the top of the first lifting layer 2.

[0044] Furthermore, the first lifting layer 2 and the second lifting layer 7 are telescopic structures. When the first lifting layer 2 and the second lifting layer 7 are in a contracted state, the two lifting layers are each one standard section length. When the first lifting layer 2 and the second lifting layer 7 are in an extended state, the two lifting layers are each two standard section lengths.

[0045] Preferably, the bottom end of the first lifting layer 2 is provided with a bottom support steel beam 11, the middle support steel beam 12 is provided between the first lifting layer 2 and the second lifting layer 7, the top end of the second lifting layer 7 is provided with a top support steel beam 13, each support steel beam 1 is selectively connected and fixed to the building structure support point, and the main structure of the internal climbing tower crane is set on the top support steel beam 13.

[0046] Preferably, the first lifting layer 2 and the second lifting layer 7 are each equipped with a hydraulic system. The two ends of the hydraulic system in the first lifting layer 2 are connected to the bottom support steel beam 11 and the middle support steel beam 12, respectively. The bottom end of the hydraulic system in the second lifting layer 7 is located on the middle support steel beam 12. The lifting mechanism is driven by the reciprocating extension and retraction of the hydraulic systems 3 in the first lifting layer 2 and the second lifting layer 7, thereby driving the main structure to climb.

[0047] Specifically, the first lifting layer 2 contains a bottom-level hydraulic system 301, which includes four hydraulic jacks, respectively positioned around the perimeter of the first lifting layer 2. The second lifting layer 7 contains a top-level hydraulic system 302, which includes eight hydraulic jacks, evenly positioned around the perimeter of the second lifting layer 7. Each hydraulic jack is rigidly connected to the supporting steel beam 1.

[0048] Preferably, each layer of supporting steel beam 1 includes: a steel beam frame 101, a wall support arm 102, and a structural beam support arm 103. The wall support arm 102 and the structural beam support arm 103 are respectively arranged on both sides of the steel beam frame 101 and can extend and retract to complete the connection and fixation with the corresponding supporting structure or disconnect the connection. That is, the support arms extend and retract within a certain range. When the two support arms are retracted, the tower crane can continuously climb upward in the shaft. When the two support arms are extended, the tower crane can stably support the shaft structure. Moreover, each lifting layer is rigidly connected to the steel beam frame 101.

[0049] Furthermore, the end of the wall support arm 102 is a circular pad, used to generate friction by contacting the supporting building wall. The end of the structural beam support arm 103 is an "L-shaped" bayonet structure, which can cooperate with the structural beam 6 supporting the building to obtain an upward supporting force.

[0050] Preferably, the wall support arm 102 is also equipped with a hydraulic servo system (based on the pressure value N0 detected by data transmission, combined with F = mN, given the friction force F, the value of N is determined, where m is the coefficient of friction, so that N0 > N, thereby ensuring the stability of the tower structure system). When it is necessary to fix the tower crane, the wall support arm 102 extends and contacts the wall structure. If the interaction force is lower than the critical value, the hydraulic system 3 continues to pressurize so that the friction force at the wall meets the condition of supporting the self-weight of the tower crane tower body.

[0051] Preferably, the first lifting layer 2 and the second lifting layer 7 are provided with a pulley system 4 on their sides, and each pulley in the pulley system 4 makes rolling contact with the side wall of the surrounding supporting structure.

[0052] Pulley system 4 (this component is an adaptive rotatable component, designed for attachment to the inner wall of the elevator shaft in at least three directions. Attachment points can be on the wall itself or at a corner. Generally, the shaft has three walls and one doorway, which allows for good guidance and support of the pulleys. For areas with two open sides, external guide steel sections can be used between the upper and lower beams for connection.) is fixed to the steel columns surrounding the first lifting floor 2 and the second lifting floor 7. Figure 3As shown, when the lifting mechanism climbs in the shaft, the pulleys around the lifting layer slide on the wall and structural beams, and at the same time generate a mutual supporting force with the main structure, preventing the tower body from overturning or swaying during the climbing process, which helps to improve the stability of the internal climbing tower crane during the climbing process.

[0053] The climbing process of the jacking mechanism in the adaptive internal climbing tower crane of this invention includes:

[0054] refer to Figure 5 As shown, the initial stage of the lifting mechanism is as follows: the first lifting layer 2 is in a retracted state, and the second lifting layer 7 is in an extended state, that is, the first lifting layer 2 is one standard section length, and the second lifting layer 7 is two standard section lengths.

[0055] refer to Figure 6 As shown, when the lifting mechanism starts to climb, the bottom support steel beam 11 and the top support steel beam 13 are fixed to the support structures on both sides respectively; the middle support steel beam 12 is disconnected from the support structures on both sides, the first lifting layer 2 extends and drives the middle support steel beam 12 to move upward until the first lifting layer 2 extends to the length of two standard sections, and the second lifting layer 7 contracts to the length of one standard section.

[0056] refer to Figure 7 As shown, the middle layer support steel beam 12 is then fixedly supported by the two side support structures, the bottom layer support steel beam 11 is disconnected from the two side support structures, the first lifting layer 2 is shortened to the length of a standard section, at this time the bottom layer support steel beam 11 is lifted by a standard section, and then the bottom layer support steel beam 111 is fixedly connected to the two side support structures.

[0057] Then, the connection between the top-level support steel beam 13 and the support structures on both sides is disconnected. The second lifting layer 7 is extended by the hydraulic system until it extends to two standard sections, and the connection between the top-level support steel beam 13 and the support structures on both sides is completed. This causes the main structure of the adaptive internal climbing tower crane to climb one standard section, and at this time, the lifting mechanism of the adaptive internal climbing tower crane returns to its initial stage state. At this time, the tower crane completes one stroke of climbing operation. When the main structure needs to be continuously and efficiently constructed, the above operation procedure is repeated, and the tower crane can be continuously climbed to the working height to complete the construction work of the main structure.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
