Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of construction machinery, and specifically relates to a tower crane attached pull rod connecting component. BACKGROUND

[0002] As an indispensable important equipment on construction sites, tower cranes play a key role in construction and can efficiently hoist various building materials and construction machinery, significantly improving construction efficiency. When the working height of the tower crane exceeds the independent height, attachment operation is required to ensure its stability and safety. Common attachment devices include attachment frames, adjustable attachment rods, and attachment bases, among which the conventional four-pole attachment form is mostly M-shaped.

[0003] However, in actual construction scenarios, when the tower crane is installed on the outside of a bridge pier and uses M-shaped attachment, obvious problems arise. The structural layout of M-shaped attachment occupies a large space on the side of the bridge pier, resulting in the installation location required for the construction elevator being occupied, leaving insufficient space to install components such as the guide rail and car of the elevator, and due to the special shape and fixing method of M-shaped attachment, a complex stress structure may be formed on the side of the bridge pier, making the installation of the construction elevator unable to meet the requirements of structural safety and stability, resulting in the inability to install the construction elevator, which seriously affects the normal vertical transportation of construction personnel, brings great inconvenience to construction progress and personnel flow, and increases the complexity and safety risks of construction.

[0004] To address the above problems, there are currently the following solutions:

[0005] Change the layout form of the attachment rod, such as using an L-shaped or other asymmetric structure. The advantage of this method is that it can avoid excessive occupation of space on the side of the bridge pier, making it possible to install the construction elevator, but the disadvantage is that it may cause the stability of the attachment structure to be relatively reduced, requiring more complex calculations and design to ensure safety.

[0006] Adjust the position of the attachment point by setting it at other parts of the bridge pier to avoid the installation area of the construction elevator. The advantage of this method is that it requires less structural modification of the attachment rod, but it may be limited by the structure and stress of the bridge pier and may not be feasible in all cases. INVENTION CONTENTS

[0007] To address the deficiencies of existing technology, the technical problem solved by the utility model is to provide a tower crane attachment pull rod connecting component that facilitates the installation of the attachment pull rod without affecting the installation of the construction elevator.

[0008] In order to solve the above problems, the technical scheme adopted by the utility model is: a tower crane attached pull rod connecting component, including connecting component, the connecting component includes lug plate, connecting plate, the lug plate is multiple, and the lug plate is fixedly connected through the connecting plate, the lug plate is symmetrically arranged, and is arranged in matrix array on the connecting plate, and the connecting hole is correspondingly arranged on the lug plate, the lug plate and the connecting plate form two mirror image V-shaped structure arrangement.

[0009] The principle of the scheme is: by symmetrically arranging multiple lug plates and arranging them in matrix array on the connecting plate, a stable support structure is formed, and the lug plate and the connecting plate form two mirror image V-shaped structures, which are specially designed to evenly distribute the force to each lug plate when the connecting component bears the tension or pressure, thereby improving the overall carrying capacity, and the symmetrically arranged lug plates ensure the balance of the force, avoid the structure damage caused by excessive local force, and the matrix array distribution further enhances the stability of the structure, so that the connecting component can maintain good working condition under the action of force in different directions and angles.

[0010] The two mirror image V-shaped structures provide sufficient strength while effectively optimizing the space layout, reducing the occupation of the surrounding space, and adapting to the installation requirements of the tower crane in complex construction environment.

[0011] The beneficial effects of the scheme are:

[0012] Multiple lug plates are fixedly connected through the connecting plate, which enhances the strength and stability of the overall structure, the lug plates are symmetrically arranged and distributed in matrix array on the connecting plate, so that the force can be evenly transmitted and dispersed, avoiding the structure damage caused by excessive local force, and providing a solid guarantee for the safe operation of the tower crane.

[0013] The lug plate and the connecting plate form two mirror image V-shaped structure arrangement, which can effectively reduce the occupation of the connecting component to the surrounding space in the limited space environment such as the outside of the pier, reserve enough space for the installation and operation of other construction equipment, solve the problem of space congestion caused by the connecting component in the past, and the connecting hole correspondingly arranged on the lug plate provides convenience for installation and disassembly, at the same time, in the subsequent maintenance and replacement work, the disassembly and replacement of parts can also be quickly carried out, reducing the construction cost and time cost.

[0014] Further, the ear plate is provided with a diamond-shaped structure through the connecting plate, and the opposite corners of the diamond-shaped structure are provided in a circular arc structure, so that the stress can be more evenly dispersed when the diamond-shaped structure bears forces from different directions, reducing the phenomenon of stress concentration, thereby improving the carrying capacity and durability of the connecting member, ensuring that deformation or damage does not easily occur during long-term use, and providing more reliable protection for the safe operation of the tower crane, and the arc-shaped corners can effectively reduce stress concentration, so that the stress distribution inside the structure is more uniform when stressed, further enhancing the strength and fatigue resistance of the structure, and the arc-shaped structure allows the attachment rod to rotate when connected to the ear plate through the connecting hole, facilitating the installation and removal of the attachment rod.

[0015] Further, the upper and lower ends of the connecting member are respectively provided with attachment rods connected with the connecting holes, and the upper and lower ends of the attachment rod are respectively connected with an attachment plate and an attachment frame, so that a stable connection network is formed through the cooperation of the connecting member, the attachment rod, the attachment plate and the attachment frame, which can effectively uniformly transmit the load of the tower crane to the building or other supporting structure, reducing the risk of local overload and instability, and when the dynamic load generated by the operation of the tower crane is transmitted through the attachment rod, the attachment plate and the attachment frame can play a certain buffering role, reducing the impact on the connecting member and other components, and prolonging the service life of the entire attachment system.

[0016] Further, the lower end of the attachment plate is provided with a plurality of connecting heads arranged in a matrix array on the base of the attachment plate, so that when the attachment plate bears the load from the tower crane, the load can be uniformly transmitted to the base through the cooperation of the plurality of connecting heads, avoiding structural damage or deformation caused by excessive local stress, thereby enhancing the carrying capacity and stability of the entire attachment plate, and a plurality of connecting heads share the load, so that even if individual connecting heads are slightly loose or damaged, other connecting heads can still ensure the normal operation of the attachment plate, reducing the risk of failure of the entire attachment system due to a single point failure.

[0017] Further, a gasket is arranged at the bottom end position of the attachment plate, and the gasket is a shock-absorbing gasket, which cooperates with the connecting head, so that when the tower crane vibrates and impacts during operation, the shock-absorbing gasket can effectively absorb and buffer these energies, reducing the damage of vibration and impact to the attachment plate and the entire connecting structure, prolonging the service life of the equipment, the existence of the shock-absorbing gasket can compensate for the small gap and unevenness that may exist between the connecting head and the attachment plate, making the connection more tight and stable, reducing the risk of connection failure due to looseness, and the shock-absorbing gasket can reduce the wear and fatigue damage of the connecting head and the attachment plate during long-term use, reducing maintenance costs and repair frequency.

[0018] Furthermore, the attachment plate is provided with two protruding connectors, which are arranged in an arc-shaped groove. When the attachment plate is subjected to external force, the arc-shaped groove can guide the stress to be distributed more evenly on the structure of the connectors and the attachment plate, reducing stress concentration and lowering the risk of breakage or deformation of the connectors and the attachment plate, thereby enhancing the strength and durability of the overall structure.

[0019] Furthermore, a stiffening rib is provided near the connecting plate of the ear plate. The stiffening rib can effectively resist the bending and shear stress at the connection between the ear plate and the connecting plate, and prevent excessive deformation or damage to this part when under stress, thereby improving the load-bearing capacity and stability of the entire connecting component.

[0020] Furthermore, the extension lines of the attachment rods are arranged in a cross configuration, forming two triangular structures on the connecting member. The cross configuration of the attachment rods can more evenly distribute the load from the tower crane, making the force borne by each rod relatively small, thereby extending the service life of the rods and reducing the possibility of damage to the rods due to overload.

[0025] Example 1 is basically as shown in the appendix. Figures 1-3 As shown: A tower crane attachment tie rod connecting component includes a connecting component 7, which includes ear plates 9 and connecting plates 8. Multiple ear plates 9 are provided in the connecting component 7 and are fixedly connected by the connecting plates 8. The ear plates 9 are symmetrically arranged and distributed in a matrix array on the connecting plates 8. Corresponding connecting holes 11 are provided on the ear plates 9. The ear plates 9 and the connecting plates 8 form two mirror V-shaped structures, which can effectively distribute the force, improve the stability of the connecting component 7 when subjected to tension or compression, and reduce the risk of structural damage caused by excessive local stress.

[0026] And the ear plate 9 is provided with a connecting member in a diamond structure through the connecting plate 8, the opposite corners of the diamond structure are in a circular arc structure, the circular arc structure can reduce stress concentration, enhance the strength and fatigue resistance of the structure, and make the connecting member 7 not easy to deform or damage in long-term use.

[0027] The upper and lower ends of the connecting member 7 are respectively provided with an attached pull rod 3 matched with a connecting hole 11, and the upper and lower ends of the attached pull rod 3 are respectively connected with an attached plate 2 and an attached frame. When the tower crane is working, the load can be uniformly transmitted to the building or other support structure through the cooperation of the connecting member 7, the attached pull rod 3, the attached plate 2 and the attached frame, effectively reducing the risk of local overload and instability. At the same time, the lower end of the attached plate 2 is provided with a plurality of connecting heads 5 distributed in a matrix array, which can uniformly transmit the load and avoid structural damage or deformation caused by excessive local stress, thereby enhancing the overall load-carrying capacity and stability of the attached plate 2.

[0028] A gasket 6 is arranged at the bottom end position of the attached plate 2, which is a damping gasket 6. When the tower crane vibrates and impacts during work, the damping gasket 6 can effectively absorb and buffer these energies, reducing the damage of vibration and impact on the attached plate 2 and the entire connecting structure, prolonging the service life of the equipment. At the same time, the damping gasket 6 can also compensate for the small gap and unevenness between the connecting head 5 and the attached plate 2, making the connection more tight and stable.

[0029] Two protruding connecting heads 5 are arranged on the attached plate 2, and the connecting heads 5 are arranged in an arc-shaped groove. The arc-shaped groove can guide the stress to be more evenly distributed on the structure of the connecting head 5 and the attached plate 2, reducing the risk of fracture or deformation of the connecting head 5 and the attached plate 2, and enhancing the strength and durability of the overall structure.

[0030] A rib plate 10 is arranged at the position close to the connecting plate 8 of the ear plate 9. The rib plate 10 can effectively resist the bending and shearing stress at the connection between the ear plate 9 and the connecting plate 8, prevent excessive deformation or damage of this part under stress, and improve the load-carrying capacity and stability of the entire connecting member 7.

[0031] Moreover, the extension lines of the attached pull rod 3 are arranged in a cross shape, and the attached pull rod 3 on the connecting member 7 forms two triangular structures. This cross arrangement can more evenly share the load from the tower crane, so that each pull rod bears relatively small force, prolongs the service life of the pull rod, and reduces the possibility of damage of the pull rod due to overload.

[0032] In the actual installation process, first, the components of the connecting member 7 are assembled to form a stable whole, the attachment pull rod 3 is connected with the connecting hole 11 of the connecting member 7, and the other end of the attachment pull rod 3 is connected with the attachment plate 2 and the attachment frame respectively, so as to ensure the safety and stability of the tower crane during the working process.
