Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant steel structure towers, in particular to an earthquake-resistant steel structure tower. Background Art

[0002] In some projects, towers are needed as auxiliary, mainly used for supporting factory chimneys, large building supports, water towers, monitoring projects, communication projects and other special purposes. One of the most common ones is the earthquake-resistant steel structure tower;

[0003] The existing earthquake-resistant steel structure tower consists of a tower body, a connecting frame, a fixing device, a mounting base and other structures. The tower body is installed at a designated position using the mounting base, and then the connecting frame and the fixing device are used to cooperate to achieve the function of support or connection;

[0004] However, when the existing earthquake-resistant steel structure tower is being repaired and maintained, some auxiliary components need to be carried to the designated location by the staff, and the heavy structural parts need to be assisted by equipment such as cranes, which makes the repair and maintenance work more cumbersome and inefficient. In addition, the earthquake-resistant effect of the existing earthquake-resistant steel structure tower cannot achieve the ideal earthquake-resistant effect, which makes the tower prone to shaking during use; therefore, a earthquake-resistant steel structure tower is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve some existing problems of earthquake-resistant steel structure tower frames, the utility model proposes an earthquake-resistant steel structure tower frame.

[0006] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model discloses an earthquake-resistant steel structure tower, comprising a tower; a structural frame is installed between the vertical rods of the tower; a top frame is installed on the top of the tower; a lifting device is installed on the tower; the lifting device comprises a fixing plate; a fixing plate is welded on the side of the vertical rod opposite to the tower; a connecting plate is fixedly connected to the outer arc surface of the fixing plate; a slot is provided on the connecting plate near the fixing plate; a block is provided inside the slot; an action box is fixedly connected to the end of the block; a rotating chamber is provided inside the action box;

[0007] A small motor is installed on the end face of one side of the inner wall of the rotating chamber; a rotating shaft is installed on the end of the output shaft of the small motor; the end of the rotating shaft is rotatably installed on the end face of the other side of the inner wall of the rotating chamber; a gear is installed on the outer sleeve of the cross-section of the rotating shaft; a structural groove is opened on the side of the connecting piece; gear teeth are equidistantly installed inside the structural groove; the gear teeth are meshed with the gears; a telescopic rod is installed between the action boxes; a support plate is installed on the end of the telescopic rod; a bracket is opened on the top of the support plate; a rapid lifting effect on the structural parts is achieved.

[0008] Preferably, the rotation range of the gear does not intersect with the rotation cavity; the length of the gear is smaller than the opening depth of the structural groove; thus ensuring that the gear can move normally.

[0009] Preferably, when the action box is located at the bottom of the tower, the telescopic rod can be stretched to the longest length; when the action box moves to the top of the tower, the stretched length of the telescopic rod is the shortest at this time, ensuring that the support plate can smoothly play a lifting role.

[0010] Preferably, the action range of the bracket cross section can cover the action range of the cross section of the weight block; the action range of the top frame cross section can cover the action range of the support plate; this ensures that the weight block can be lifted smoothly and facilitates subsequent maintenance.

[0011] Preferably, a shockproof device is installed on the top frame; the shockproof device includes a ring; a ring is installed on the outside of the cross-section of the top cross bar of the top frame; a connecting rod is fixed between the outer side surfaces of the ring; a fixing ring is fixed to the bottom of the connecting rod near the center point; a pull rod is installed on the fixing ring through an action hole; a weight block is installed on the bottom of the pull rod through a pin shaft; the shockproof effect of the tower is improved.

[0012] Preferably, the installation distance between adjacent fixing rings is smaller than the cross-sectional dimension of the weight block; the length of the pull rod is smaller than the length of the connecting rod; thus ensuring that the pull rod can function smoothly.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model uses the structural design of the lifting device to open the small motor inside the action box, and the rotating shaft inside the rotating cavity drives the gear to rotate. Under the action of the gear teeth in the structural groove, the clamping block drives the action box to move upward along the direction of the clamping groove. Under the action of the telescopic rod, the support plate moves upward, and the structural parts in the bracket move upward along the direction of the fixing plate, which is convenient for the repair and maintenance of the tower, and can quickly transport the structural parts to the top of the tower, and also facilitates the installation of the subsequent anti-vibration device.

[0015] 2. The utility model adopts the structural design of the shockproof device. After the tower is affected by the lateral wind force, the swing force is transmitted to the top frame through the tower, and then transmitted to the connecting rod by the sleeve ring. Under the action of the fixed ring, the pull rod drives the heavy block to swing, which plays the role of a damper, realizes the shock-absorbing effect on the tower, and improves the stability of the tower.

[0028] Working principle: In some projects, towers are needed for auxiliary purposes, mainly for supporting factory chimneys, large building supports, water tower towers, monitoring projects, communication projects and other special purposes. A common one is the earthquake-resistant steel structure tower.
