Description

Technical Field

[0001] The utility model relates to the field of crane equipment, in particular to a tower crane positioning and anti-swaying device. Background Art

[0002] As a common lifting equipment in the construction industry, tower cranes are widely used in various engineering constructions to provide heavy object transportation for construction. When building a tower crane, the most important thing is to ensure the stability of the tower crane, because the tower crane is an aerial work equipment. If it is unstable, it is easy to cause hidden dangers to building safety. Therefore, the existing tower crane will install a counterweight block at the end of its cross arm to achieve the purpose of balancing and stabilizing the front and rear lever arms; however, for the overall structure of the tower crane, it is necessary not only to ensure the stability of its lever arm, but also to ensure the stability of its supporting body. The supporting body of the current tower crane is built in combination, that is, the supporting body is stacked up layer by layer, and the supporting body is connected by a connector to form the supporting body of the tower crane. However, although this method is more convenient to build, in harsh weather such as strong winds, the supporting body will shake violently due to the gap in the connection position, thereby affecting the safety of the tower crane in special environments.

[0003] Based on the above problems, there is a need for a tower crane positioning and anti-sway device that can help stabilize the main structure of the tower crane to prevent the supporting body of the crane from swinging significantly under the action of external forces, thereby providing suitable operating conditions for high-altitude workers and the high-altitude working environment. Utility Model Content

[0004] The purpose of the utility model is to provide a tower crane positioning and anti-sway device, which can help stabilize the main structure of the tower crane to prevent the supporting body of the crane from swinging to a large extent under the action of external force, thereby providing suitable operating conditions for workers working at high altitudes and the environment of high altitude operations.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions:

[0006] A tower crane positioning and anti-sway device comprises a fixing part and a traction rope body, wherein a plurality of the fixing parts are respectively arranged at adjacent support assembly positions, and the traction rope body is used to connect a plurality of fixing parts at the same vertical position; a plurality of the traction rope bodies are respectively arranged at different outer edge positions of the support assembly, and a fixing part is arranged at the outer edge position of each support assembly in cooperation with the traction rope body.

[0007] The traction rope body is cooperatively connected with a tightening mechanism, and the traction rope is tightened by the tightening mechanism.

[0008] The fixing member is a fixing slot plate, and a bolt fastening assembly is arranged on the fixing slot plate, and the fixing slot plate is fixedly arranged at a connecting position of an adjacent supporting assembly by the bolt fastening assembly.

[0009] The fixed groove plate is provided with a traction through hole, and the traction rope body is arranged through the traction through hole.

[0010] The tightening mechanism is a tightening winch, which is arranged at the lower end of the traction rope body, and different traction rope bodies are individually connected to different tightening winches.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When setting up this device, by setting up the fixing parts and the traction rope body, the tower crane will not have a violent shaking problem when it is subjected to external force. When setting up, firstly, the fixing parts are fixedly installed and set to the connection position of the adjacent support assembly, and the adjacent support assembly of the tower crane is firmly fixed again by the fixing parts; secondly, the multiple fixing parts are tightened by the traction rope body, so that the traction rope body can pull one side of the tower crane, so that when the tower crane is subjected to external force, it can remain stable in the vertical direction of the traction rope body setting, thereby avoiding the tower crane from having a violent shaking problem.

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0019] Because when a tower crane is currently installed and constructed, its supporting body is composed of various supporting components 3, and adjacent supporting components 3 are connected by fixing mechanisms such as bolts, thereby realizing the construction of the supporting body of the tower crane. If the tower crane needs to be increased in height later, the supporting component 3 can be installed on the supporting body to realize the operation of increasing the height of the supporting body. However, after the supporting components 3 are constructed in multiple components, the constructed supporting body will also change in shape when subjected to external forces; for example, in windy weather, the force applied to the supporting body of the tower crane will cause the connection position of the supporting component 3 to move, thereby causing the supporting body to shake and swing violently, thereby causing safety hazards to normal construction on the construction site.

[0020] Therefore, it is necessary to set up a tower crane positioning and anti-sway device, including a fixing part 1 and a traction rope body 2. A plurality of the fixing parts 1 are respectively arranged at adjacent support components 3, and the traction rope body 2 is used to connect the plurality of fixing parts 1 at the same vertical position; a plurality of the traction rope bodies 2 are respectively arranged at different outer edge positions of the support components 3, and the fixing parts 1 are arranged in conjunction with the traction rope body 2 at the outer edge position of each support component 3. The fixing part 1 arranged here is used to fix the adjacent support components 3 again, so as to further reinforce the adjacent support components 3, so that the constructed support body can further resist the swing problem caused by external forces. The most important thing is that here, a plurality of fixings 1 are connected by a traction rope 2, and the position of the traction rope 2 in the vertical direction of the support body is limited by the plurality of fixings 1, and the traction rope 2 is kept in a taut state when in use; when an external force is applied to the support body of the tower crane, the support body will shake, and because the traction rope 2 is in a taut state at this time, when the support body shakes toward the side away from the traction rope 2, the traction rope 2 can prevent the support body from moving away from the traction rope 2, thereby achieving a traction effect on the swing direction of the support body to reduce the swing amplitude of the support body. In order to ensure that the support body can achieve the purpose of reducing the vibration amplitude in all directions, the plurality of traction ropes 2 are respectively arranged at different outer edge positions of the support assembly 3, and the fixings 1 are arranged in cooperation with the traction rope 2 at the outer edge position of each support assembly 3, so that the purpose of traction of the support body can be achieved in multiple positions and directions, so as to reduce the vibration amplitude of the support body when it is subjected to external force. When setting the specific number of traction rope bodies 2 here, it should be set according to the specific situation of the tower crane. For example, for a tower crane support body with a triangular structure in horizontal cross-section, selecting three traction rope bodies 2 and fixing parts 1 for setting is more in line with the construction requirements.

[0021] Further design and optimization of the above structure:

[0022] Because when the traction rope 2 is in use, the traction rope 2 needs to be kept in a taut state, so that when the support body is shaking, the traction rope 2 can effectively pull the support body. Therefore, the traction rope 2 is connected with a tightening mechanism, and the traction rope is tightened by the tightening mechanism; as for the specific structural setting of the tightening mechanism, the tightening mechanism is a tightening winch, and the tightening winch is arranged at the lower end position of the traction rope 2, and different traction ropes 2 are individually connected to different tightening winches; the tightening of the traction rope 2 is achieved by the tightening winch, so as to achieve the purpose of facilitating the installation and tightening of the traction rope 2. For the tightening winch here, it can be set in conjunction with the driving motor, and the purpose of automatic tightening of the traction rope 2 can be achieved by driving the electric motor to cooperate with the tightening winch, so as to meet the demand for automatic tightening of the traction rope 2.

[0023] The specific structure of the fixing member 1 is set: the fixing member 1 is a fixing slot plate 4, and a bolt fastening assembly is provided on the fixing slot plate 4, and the fixing slot plate 4 is fixedly set at the connecting position of the adjacent supporting assembly 3 by the bolt fastening assembly, so as to further stabilize the adjacent supporting assembly 3. A traction through hole 5 is provided on the fixing slot plate 4, and the traction rope body 2 is arranged to pass through the traction through hole 5, so as to facilitate the position of the traction rope body 2 to be limited by the fixing slot plate 4.

[0024] It should be noted here that because the traction rope body 2 in the present device will bear a relatively large traction force, it is necessary to select a traction steel rope with relatively high strength for setting so as to be able to meet the traction requirements when the tower crane is swinging.

[0025] Therefore, a tower crane positioning and anti-sway device can help stabilize the main structure of the tower crane to prevent the supporting body of the crane from swinging significantly under the action of external force, thereby providing suitable operating conditions for workers working at high altitudes and the environment of high altitude operations.
