Description

Technical Field

[0001] The utility model belongs to the technical field of tower cranes, and in particular relates to a telescopic reinforcement combined bracket for a tower crane foundation. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is used to lift raw materials such as steel bars, wooden planks, concrete, and steel pipes for construction. Tower crane is an indispensable equipment on construction sites. The function of the tower crane tip is to bear the upper load transmitted by the arm rope and the balance arm rope, and directly transmit it to the tower structure through the turntable through the structural components such as the rotating tower, turntable, and bearing. The self-elevating tower top has truncated cone column type, forward or backward truncated cone column type, herringbone type, and diagonal support frame type. Since the tower crane relies on the suspended boom to lift heavy objects, the tower crane has a very large tipping moment, and the bearing capacity requirements of the foundation are also high, so the tower crane foundation is very important and is a necessary condition for maintaining the safe operation of the tower crane.

[0003] On the other hand, the foundation of a tower crane is generally made of concrete. The length, height, width and reinforcement of the foundation need to meet the requirements of the overturning stability of the tower crane, the bearing capacity of the foundation, and the crack resistance of the foundation. The foundation of a tower crane generally includes four foundation piles and a base for installing the tower crane. Its firmness and stability directly affect the safety of the tower crane, so a reinforcement structure is usually set for the tower crane foundation.

[0004] The Chinese utility model patent with the utility model patent announcement number CN210289218U and the announcement date of April 10, 2020, discloses a tower crane foundation reinforcement device, the structure of which includes a connecting rod, a splicing rod, a clamping block and a reinforcement rod. Two splicing rods are arranged between the connecting rods, and a fixing block is welded in the middle of the connecting rod. The fixing blocks are respectively clamped at the two ends of the reinforcement rod, and the reinforcement rods are respectively tightly attached to the middle of the connecting rod. Two grooves are arranged in the inner wall opening of the connecting rod, and two springs are welded inside the splicing rod, and a fixing block is welded at one end of the spring, and a fixing groove is opened at both ends of the reinforcement rod.

[0005] The general structural principle of the tower crane foundation reinforcement device in this utility model patent is as follows: first, a splicing rod is placed tightly against the bottom of the tower crane, and then two connecting rods are placed at both ends of the splicing rod, and then another splicing rod is inserted between the two connecting rods, so that the two connecting rods and the two splicing rods are sleeved at the bottom of the tower crane, and the fixed blocks in the splicing rods are inserted into the grooves, and then according to the above operations, the bottoms of the other two connecting rods and the two splicing rod sleeves are sleeved, so that the four connecting rods and the four splicing rod sleeves respectively form two frames sleeved at the bottom of the tower crane, and finally the two frames are moved up and down, and the two ends of the two reinforcement rods are respectively clamped on the clamping blocks, so that the two reinforcement rods are connected to the two sides of the two frames, so as to avoid bending of the tower crane when it is subjected to force, increase the force-bearing capacity of the bottom of the tower crane, and ensure the stability of the bottom of the tower crane.

[0006] However, the tower crane foundation reinforcement device still has at least the following deficiencies during actual use, in other words, which are the technical problems to be solved by the present utility model.

[0007] The tower crane foundation reinforcement device only reinforces the entire tower crane foundation, lacks reinforcement and force balance for each foundation pile, and has poor vibration isolation capability.

[0008] Therefore, in summary, there is an urgent need for a new type of retractable reinforced composite bracket for tower crane foundation that can balance the stress of each foundation pile. Utility Model Content

At the same time, the telescopic sleeve hoop unit can be adjusted according to the specifications of different tower crane foundation piles, and can meet the reinforcement requirements of foundation piles of different specifications. The horizontal connecting rod unit reinforces the foundation piles horizontally, and the inclined reinforcement rod unit reinforces the foundation piles axially. The stability of the tower crane foundation is better, and the risk of safety accidents is reduced.

[0032] In this embodiment, there are four foundation piles a, and the foundation platform b is arranged on the foundation piles a for installing a tower crane. The telescopic hoop unit 1 is used to reinforce the foundation piles a, and is arranged on the foundation piles a in a corresponding arrangement. The horizontal connecting rod unit 2 is arranged on the telescopic hoop unit 1 to connect adjacent foundation piles a, and the inclined reinforcement rod unit 3 is used to vertically connect adjacent foundation piles a.

[0033] In addition, the telescopic sleeve unit 1 is sleeved on the foundation pile a, and each foundation pile a can be reinforced individually, and the overall tower crane foundation can be shock-absorbing; the function of the horizontal connecting rod unit 2 is to connect and reinforce the telescopic sleeve unit 1 sleeved on the foundation pile a, enhance the integrity, and improve stability and compressive resistance; the inclined reinforcement rod unit 3 reinforces the telescopic sleeve unit 1 and another telescopic sleeve unit 1 with a height difference to form a triangular stable space, increase the stability and compressive resistance of the telescopic reinforcement combined bracket for the tower crane foundation and the foundation pile a, and make the overall force more uniform and reasonable. At the same time, the telescopic reinforcement combined bracket for the tower crane foundation can be disassembled and recycled after use.

[0034] The telescopic sleeve unit 1 includes four L-shaped corner plates 101 arranged on the foundation pile a, and an adjustment sleeve 102 sleeved on both ends of the L-shaped corner plates 101 and used to tighten the foundation pile a.

[0035] In this embodiment, if Figure 3As shown, the L-shaped corner plate 101 wraps around the four corners of the foundation pile a, and then the L-shaped corner plate 101 is connected into a whole using the adjusting sleeve 102, and the foundation pile a is fixed. Secondly, the adjusting sleeve can be adjusted to change the distance at which the L-shaped corner plate 101 is embedded in the adjusting sleeve 102, thereby adapting to foundation piles a of different specifications, with greater flexibility.

[0036] Two adjusting sleeves 102 are arranged between adjacent L-shaped corner plates 101 , and the telescopic sleeve unit 1 further includes a threaded fixing plate 103 arranged between the two adjusting sleeves 102 .

[0037] In this embodiment, if Figure 4 As shown, the adjusting sleeve 102 is broken into two, and the threaded fixing plate 103 is inserted between the broken adjusting sleeves 102. The threaded fixing plate 103 does not rotate with the adjusting sleeve 102, which is convenient for installing the vertical orifice plate 301. Limit blocks can be set on both sides of the threaded fixing plate 103 to prevent the adjusting sleeve 102 from being relatively far away from the L-shaped corner plate 101 and then being embedded into the threaded fixing plate 103, thereby affecting the adjustment efficiency.

[0038] The horizontal connecting rod unit 2 includes a transverse perforated plate 201 disposed on the L-shaped corner plate 101 and a mounting cross bar 202 disposed on the transverse perforated plate 201 and used to connect the transverse perforated plate 201 on the adjacent foundation a.
