Description

Technical Field

[0001] The present invention specifically relates to a tower construction machine template hanging mechanism used for tower construction, and relates to the technical field of tower construction hanging. Background Art

[0002] In the traditional construction process of the tower, the installation of the template is an important link. When the template on the ground needs to be hoisted to the tower crane, the common method is to use a crane with a hook for hoisting. However, this method lacks multi-directional constraints and dynamic balance, and the construction risk is extremely high. Due to the complex construction environment of the tower, such as under the influence of external factors such as wind, this single hanging method makes it easy for the template to tilt and slide on the hook. Once the template tilts, it will not only affect the accuracy of its installation, but also may cause safety hazards, such as the curtain wall colliding with other structural components of the tower, causing damage to components or the curtain wall itself; In addition, the crane hook structure does not have a good elastic buffering effect. During the lifting process, since the lifting and stopping actions of the crane are often not completely smooth, a certain impact force will be generated. This impact force may cause damage to the formwork, which requires precise installation, or cause the wire rope to break due to stress problems, thereby affecting the installation quality and subsequent use performance of the entire curtain wall. Therefore, it is urgent to provide an efficient, stable and safe tower crane formwork hanging mechanism for tower construction to improve the above problems. Summary of the invention

When the movable hook is hung on the hanging ring at the top of the template, the tensioning member is used to support the middle part of the upper side of the template for tensioning.

[0005] A further improvement based on the above technical solution is that the buffer assembly includes a U-shaped base plate locked on the upper side of the movable plate by screws and T-shaped keys locked on the four side corners of the U-shaped base plate, and each of the T-shaped keys is obliquely connected to an elastic bracket on the front and rear opposite sides, and each end of the elastic bracket is rotatably connected to a bearing roller sleeve for rotatably installing a roller, and a plurality of limiting wheel grooves for clamping and releasing the winch wire rope are provided in the middle of the roller.

[0006] A further improvement based on the above technical solution is that the elastic bracket is formed by an upper support tube and a lower support rod that slide and nest with each other, and a buffer spring is connected between the upper support tube and the lower support rod for elastic support, the top end of the upper support tube is rotatably connected to one side of the bearing roller sleeve, and the bottom end of the lower support rod is rotatably connected to the T-key.

[0007] A further improvement based on the above technical solution is that the connecting member includes two opposite side plates, and the two side plates have inherent bottom blocks on the opposite sides, and the bottom of the bottom block is used to install a multi-directional hook. A plurality of rolling wheels are rotatably connected between the two side plates, and each of the rolling wheels is distributed in a circular array. Each of the rolling wheels is in the shape of a funnel with a concave middle part and convex ends, and the winch wire rope is hung and connected along the middle of the rolling wheels in the circular array.

[0008] A further improvement based on the above technical solution is that the multi-directional hook comprises a vertical pole fixed at the bottom of the connecting member, the four sides of the vertical pole are respectively provided with fixed hooks, and four connecting strips are respectively hung on the fixed hooks, and an upper connecting plate is fixed at the bottom of the vertical pole.

[0009] A further improvement based on the above technical solution is that the tightening member includes a screw and a screw tube threadedly mounted on the lower side of the screw, a top plate is fixed to the bottom of the screw tube, and the top of the template is abutted against by the top plate, and a lower connecting plate is installed on the top of the screw, and the lower connecting plate is locked and connected to the upper connecting plate by bolts, and when the connecting strip is connected to the top of the template in a triangle or a quadrilateral outward, the top plate is rotated downward to tighten the upper side of the template.

[0010] A further improvement based on the above technical solution is that the winch includes a first winding roller and a second winding roller connected to each other, and both ends of the hoisting wire rope are wound by the first winding roller and the second winding roller, and the middle part of the hoisting wire rope is U-shaped, and the rolling wheel of the connecting part is hung, and a winding motor is installed on one side of the first winding roller.

[0011] A further improvement based on the above technical solution is that telescopic rods for pushing the movable plate to slide forward and backward are respectively installed on both sides of the installation platform, and an embedding groove for the buffer component to fit into is opened on the upper side of the front end of the installation platform.

[0012] A further improvement based on the above technical solution is that the connecting long steel rods.

[0013] A further improvement based on the above technical solution is that the connecting strip is a steel rope.

[0014] By adopting the above technical solution, the present invention has the following advantages: The multi-directional hook member provided in the present invention is provided with connecting strips at different positions on the four sides, so that the connecting strips are hung on the hanging rings on the two sides or four sides of the top of the template in a triangular shape outward through the movable hook, thereby realizing multi-directional hanging and improving the hanging stability of the template. The four connecting strips can effectively ensure that when one or two of them are broken, the remaining connecting strips can continue to be hung, which greatly improves its use safety, and the later replacement and maintenance of the broken connecting strips are also very simple and convenient. The roller is elastically supported by a buffer component, which can effectively improve the elastic supporting effect of the roller on the hoisting wire rope, so that after the hoisting wire rope is subjected to force, its rigid load force can be greatly reduced, and the wear of the hoisting wire rope during use can be reduced. The hoisting wire rope is connected to the middle part of the rolling wheels distributed in a circular array on the connecting piece, which is also conducive to reducing the friction of the hoisting wire rope. Even if one of the rolling wheels is broken, the other rolling wheels can still ensure rolling connection with the hoisting wire rope, and the inner concave part in the middle part can be used to maintain a stable guiding effect on the hoisting wire rope. This effect can act on the multi-directional stable hanging of the template connected to the long strip, thereby greatly improving the buffering effect when hanging the template. A movable tightening part is also installed and disassembled at the bottom of the multi-directional hook. When the connecting strip is hung on the template, the tightening part can be flexibly adjusted to tighten the upper side of the template. This can ensure that each connecting strip is always in a stable triangular support or quadrilateral support state, thereby increasing its tensioning support effect. After the tightening part tightens the top surface of the template, it can also play a certain horizontal limiting effect. This limiting effect combined with the triangular hanging effect of the connecting strip can keep the template relatively stable, which is more stable and effective than the direct hanging of a single hook in the existing structure.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0017] like Figure 1-6 As shown, the present invention provides a tower crane template hanging mechanism for tower construction, comprising a template 9, an installation platform 1 arranged on an operating beam of the tower crane, a winch 3 installed on the upper side of the installation platform 1, and a winch wire rope 30 wound on the winch 3. The front end of the installation platform 1 slides inwardly and is embedded with a movable plate 2, which can be moved forward and backward to adapt to different construction requirements. In particular, during the hanging process, it is necessary to control the front and rear telescopic position of the movable plate 2 to ensure that the hanging template 9 avoids obstacles and adjusts the designated placement position forward and backward, which can make the entire hanging process more flexible and effective. Specifically, telescopic rods 102 for pushing the movable plate 2 to slide forward and backward are respectively installed on both sides of the installation platform 1, and the movable plate 2 is pushed forward and backward by the telescopic rods 102. The positions of the roller 5 and the buffer assembly 4 are adjusted to meet the lifting requirements of templates 9 of different sizes and weights, and an embedding groove 101 for the buffer assembly 4 to fit into is opened on the upper side of the front end of the installation platform 1. The embedding groove 101 provides an adaptation space for the buffer assembly 4, so as to better retract and release it, and a groove 21 is opened at the front end of the movable plate 2, and a roller 5 and a buffer assembly 4 are arranged on the front side of the movable plate 2 and are located above the groove 21. This clever distribution of the structure allows the winch wire rope 30 to hang down better, avoid mutual influence, and improve the use effect, and a plurality of limiting wheel grooves 50 for clamping the winch wire rope 30 are arranged in the middle part of the roller 5, so that the winch wire rope 30 can be guided and rolled in the designated limiting wheel grooves 50, and it is beneficial to reduce friction and wear.

[0018] In addition, the roller 5 is elastically installed at the front end of the movable plate 2 through the buffer assembly 4, which is used to elastically support the load force of the hoisting wire rope 30 on the roller 5, thereby reducing the wear of the hoisting wire rope 30 and improving the buffering effect of the start and stop of the template 9 and the service life of the accessories; the end of the hoisting wire rope 30 is elastically turned by the roller 5 and then hung downward by the groove 21 to be connected with a connecting member 51, and a multi-directional hook 6 is installed at the bottom of the connecting member 51, and connecting strips 7 are hung on the four sides of the multi-directional hook 6, and movable hooks 72 are installed at the ends of the connecting strips 7 to connect with the hanging rings on the two sides or four sides of the top of the template 9, so as to realize multi-directional constraint on the template and ensure stability during the lifting process. At the same time, the setting of the four connecting strips 7 can continue to hang when some of the connecting strips 7 are broken, which improves the safety of use and facilitates the later replacement and maintenance.

[0019] Among them, the elastic support of the roller 5 by the buffer component 4 reduces the rigid load and wear of the hoisting wire rope 30, and improves the elastic hanging effect of the hoisting wire rope 30 on the template 9. Specifically, the buffer component 4 includes a U-shaped bottom plate 41 locked on the upper side of the movable plate 2 by screws and a T-shaped key 42 locked on the four side corners of the U-shaped bottom plate 41, and each T-shaped key 42 is obliquely connected to an elastic bracket 43 on the front and rear opposite sides. The elastic support between each obliquely rotatably installed elastic bracket 43 is utilized, and the end of each elastic bracket 43 is rotatably connected to a bearing roller sleeve 44 for rotatably installing the roller 5. This installation method is not only simple and convenient, but also can better ensure that the elastic bracket 43 and the T-shaped key 42 can share the force. In order to avoid stress concentration causing the parts to break, the elastic bracket 43 is formed by an upper support tube 431 and a lower support rod 432 sliding and nesting with each other, so that the upper support tube 431 can be downwardly sleeved with the lower support rod 432 after being stressed, and a buffer spring 433 is connected between the upper support tube 431 and the lower support rod 432 for elastic support, the top end of the upper support tube 431 is rotatably connected to one side of the bearing roller sleeve 44, and the bottom end of the lower support rod 432 is rotatably connected to the T-key 42, so that the force exerted on the roller 5 can eventually act on the T-key 42, when the winch wire rope 30 is subjected to impact force, the elastic bracket 43 absorbs energy through the expansion and contraction of the buffer spring, and the roller 5 rotates freely on the bearing roller sleeve 44, further dispersing the impact force, and protecting the safety of the template 9 and the wire rope.

[0020] In this embodiment, the connecting member 51 includes two opposite side plates 511, and the two side plates 511 have inherent bottom blocks 513 on opposite sides. The bottom of the bottom block 513 is used to install the multi-directional hook 6. Four rolling wheels 512 are rotatably connected between the two side plates 511, and each rolling wheel 512 is distributed in a circular array. Such a distribution can also reduce the friction with the hoisting wire rope 30, and each rolling wheel 512 is a funnel shape with a concave middle part and convex ends. The hoisting wire rope 30 is suspended and connected along the concave middle part of the rolling wheels 512 of the circular array. This funnel shape design ensures that the hoisting wire rope 30 is not easy to derail during the hoisting process, and can ensure that it maintains balance in the middle position. The hoisting wire rope 30 contacts the four rotatably connected rolling wheels 512 on the connecting member 51, which can reduce friction. Even if one of the rolling wheels 512 breaks, the other rolling wheels 512 can still ensure the rolling connection effect, thereby improving the safety of use.

[0021] In the above technical solution, the multi-directional hook 6 includes a vertical pole 61 fixed at the bottom of the connecting member 51, and the four sides of the vertical pole 61 are respectively provided with fixed hooks 62, and four connecting strips 7 are respectively hung on the fixed hooks 62, and an upper connecting plate 63 is fixed at the bottom of the vertical pole 61. The connecting strips 7 extend from the four sides of the multi-directional hook to the top of the template, forming a triangular or quadrilateral constraint structure, which effectively limits the movement of the template in the horizontal direction and prevents it from tilting or sliding under wind or mechanical vibration.

[0022] In order to improve the fixing effect of the template 9 and the tensioning support of the connecting strips 7, a tensioning member 8 is movably disassembled at the bottom of the multi-directional hook 6, and the tensioning member 8 is located between each connecting strip 7. When the movable hook 72 is hung on the hanging ring at the top of the template 9, the tensioning member 8 is used to support the middle part of the upper side of the template 9 for tensioning, so as to prevent the movable hook 72 from being easily unhooked. At the same time, the stability of the entire structure is improved. Specifically, the tensioning member 8 includes a screw 81 and a screw tube 82 threadedly sleeved on the lower side of the screw 81. A top plate 83 is fixedly arranged at the bottom of the screw tube 82, and the top of the template 9 is abutted against the top of the template 9 through the top plate 83. A lower connecting piece 84 is installed on the top of the screw 81, and the lower connecting piece 84 is locked and connected to the upper connecting piece 63 by bolts to form a whole. When the connecting strip 7 is connected to the top of the template 9 in a triangular or quadrilateral shape outward, the top plate 83 is rotated downward to tighten the middle part of the upper side of the template 9, so as to achieve tensioning of the template 9, and horizontally support and limit it to prevent tilting, thereby further ensuring its stability during the lifting process.

[0023] In order to further improve the stability of the hanging template 9, the winch 3 includes a first winding roller 31 and a second winding roller 32 which are connected to each other, and both ends of the winding wire rope 30 are wound by the first winding roller 31 and the second winding roller 32, and the middle part of the winding wire rope 30 is U-shaped, and the rolling wheel 512 of the connecting member 51 is hung, and a winding motor 33 is installed on one side of the first winding roller 31, and the winding motor 33 drives the first winding roller 31 and the second winding roller 32 to rotate synchronously, so as to realize the smooth winding and releasing of the winding wire rope 30 and ensure the stable lifting and lowering of the template 9 connected by the connecting member 51, the connecting strip 7 and the tensioning member 8.

[0024] Among them, the connecting strip 7 can be a steel rod, which plays the role of hanging and pulling plates. The steel rod can withstand large tension and pressure and is not easy to deform. The steel rod is suitable for occasions with high requirements on force stability and durability. Embodiment 2

[0025] The structural implementation principle of this embodiment is consistent with that of the first embodiment, and the only difference is that the connecting strip 7 is a steel rope, which also plays the role of hanging and pulling the plate, but the steel rope is relatively simple and flexible when in use, and can withstand tension better, and is suitable for occasions with high requirements on cost and installation convenience. After the top plate 83 of the tightening member 8 presses against the upper side of the template 9, the steel rope can be tightened, so that the movable hook 72 is not easy to fall off the hanging ring on the template 9, and will not cause the steel rope to be entangled, which is convenient to use.

Those skilled in the art should understand that the invention is not limited to the above embodiments.
