Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to an inner climbing tower crane. Background Art

[0002] An internal climbing tower crane is a tower crane installed in a shaft-like space such as an elevator shaft or stairwell inside a building. It relies on a climbing mechanism to rise as the structure rises, and the lifting height depends on the construction height.

[0003] Internal climbing tower cranes are usually installed in the shaft-like space inside the building, such as the elevator shaft, stairwell, etc., and are supported on the floor or in the hole of the shaft wall. When the tower body is raised to the predetermined position, the legs need to be firmly fixed on the ladder steps to prevent the tower body from shaking or deflecting in the wind or during lifting operations.

[0004] When the tower crane is hoisting, the crossbeam may be damaged. If it is not discovered in time, it will cause a safety accident. When the tower crane is climbing, the traditional method is to remove and reinstall the inner climbing base section to adjust its position. This method may extend the construction period and greatly limit the improvement of work efficiency. Utility Model Content

[0005] The utility model aims to provide an inner climbing tower crane which has the characteristics of safety and high efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal climbing tower crane, comprising two connecting beams fixedly installed between two cross beams, a fixing plate fixedly installed on the top of the cross beam, a pressure sensor embedded in the top center position of the fixing plate, a slide groove is opened on one side of the cross beam, two legs are slidably sleeved on the inner side of the slide groove, and the two legs are respectively arranged at the two ends of the cross beam, and a dual-axis motor is arranged between the two cross beams.

[0007] In order to facilitate the transmission of power, as a preferred internal climbing tower crane of the utility model, a threaded rod is installed at the output end of the dual-axis motor, a movable block is threadedly sleeved on the outer side of the threaded rod, and one end of the threaded rod away from the dual-axis motor is rotatably installed on the inner side of the beam.

[0008] In order to facilitate support and positioning, as a preferred internal climbing tower crane of the utility model, two connecting rods are rotatably installed on one side of the movable block, and one end of the connecting rod away from the movable block is hinged to the support leg, and the two connecting rods correspond to the two support legs one by one.

[0009] In order to facilitate stable movement, as a preferred embodiment of the internal climbing tower crane of the utility model, connecting plates are fixedly installed on both sides of the movable block, two supporting columns are fixedly installed between the two cross beams, and the connecting plates are slidably sleeved with the supporting columns.

[0010] For supporting installation, as a preferred embodiment of the internal climbing tower crane of the present invention, a support plate is fixedly sleeved on the outer sides of the two support columns, and the upper surface of the support plate is fixedly installed with the bottom of the dual-axis motor.

[0011] For connection and installation, as a preferred embodiment of the internal climbing tower crane of the utility model, a mounting seat is fixedly installed on the top of the two connecting beams, and four mounting holes are opened on the upper surface of the mounting seat, and the mounting seat is located directly above the dual-axis motor.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the setting of fixed plates and pressure sensors, when the crossbeam is deformed due to load-bearing pressure, the fault can be promptly transmitted to the tower crane workers, and the lifting operation can be stopped in time to ensure the safety of the construction workers. The threaded rod is driven by a dual-axis motor to rotate to move the movable block, and the movable block drives the connecting rod and the support leg to move. When the height of the crane is increased or changed, the support is positioned and supported by the support legs and the elevator shaft support position to stabilize the overall support of the crane, facilitate the overall height adjustment of the crane, and avoid personnel directly entering the shaft for manual disassembly and reinstallation operations, which greatly improves safety and the overall climbing efficiency of the crane.

[0023] In this embodiment: the threaded rod 9 is driven to rotate by the dual-axis motor 8 to move the movable block 12. When the height of the crane is increased or changed, the support legs 4 and the elevator shaft support position are used to position and support the entire crane to stabilize it.

[0031] In this embodiment, the mounting seat 5 is provided to facilitate the docking, installation and fixation of the hydraulic telescopic rod of the crane with the four mounting holes, so as to facilitate the climbing operation of the entire crane.

[0032] Working principle:

[0033] First, the device is installed and connected with the hydraulic telescopic rod set for the crane climbing. When the climbing operation is performed, the threaded rod 9 is driven to rotate forward by starting the double-axis motor 8, so that the threaded rod 9 drives the corresponding movable block 12 to move, so that the movable block 12 moves to the side close to the double-axis motor 8, and the movable block 12 drives the connecting rod 14 to move, and the connecting rod 14 pulls the leg 4 back into the beam 1 to increase the height of the device. Then the double-axis motor 8 is started to drive the threaded rod 9 to rotate in the opposite direction, so that the movable block 12 moves to the side away from the double-axis motor 8, and the connecting rod 14 is driven by the movable block 12 to move, and the connecting rod 14 pushes the leg 4 to extend along the beam 1, so that the leg 4 and the elevator shaft support position are positioned and supported, which is convenient for adjusting the height of the crane as a whole. When the beam 1 is subjected to load and pressure and deforms, the fixed plate 3 is squeezed to make the pressure sensor 10 under pressure, and the pressure sensor 10 is timely transmitted to the alarm pre-set by the tower crane to remind the staff of the occurrence of the fault, and the lifting operation is stopped in time to ensure the safety of the construction personnel.
