Description

Technical Field

[0001] The utility model belongs to the technical field of large bridge construction machinery, and relates to a pier hoop for tower crane attachment wall. Background Technique

[0002] The tower crane is abbreviated as tower crane, also known as tower hoist, and originated in Western Europe. It is a rotating crane with a boom installed on the upper part of a tall tower body. It has a large working space and is mainly used for the vertical and horizontal transportation of materials and the installation of building components in building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes tower body, boom and base, etc. The working mechanism has four parts: hoisting, luffing, slewing and traveling. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc.

[0003] In bridge construction, it is necessary to establish a connection between the tower crane and the pier at a certain height to ensure the stability of the tower crane. To connect the tower crane and the pier, it is necessary to pour the embedded parts into the pier in advance when pouring the pier, so that the tower crane and the pier can be connected through the embedded parts and connecting rods. If the pouring position of the embedded parts misses the connection node during the pouring of the pier, it is difficult to connect the tower crane and the pier or the connection is not stable enough.

[0004] Based on this, we designed a pier hoop for tower crane attachment wall. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems existing in the prior art, and propose a pier hoop for tower crane attachment wall. The technical problem to be solved by this device is: how to achieve a stable connection between the tower crane and the pier when the embedded parts of the pier miss the connection node.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A pier hoop for tower crane attachment wall includes four hoop rods. The ends of the hoop rods are connected with welding plates, and the four hoop rods are bolt-connected into a rectangle through the welding plates. Two connecting ears are arranged on the hoop rods. The connecting ear includes two connecting plates for connecting the hoop rods. The two connecting plates are respectively located on the upper and lower sides of the hoop rod. A vertical plate is connected to the connecting plate, and two symmetrically distributed ear plates are connected to the vertical plate, and two connecting holes are opened on the ear plates.

[0008] The hoop rod includes two channel steels with opposite openings, and a number of equally spaced fixing plates are welded on the upper and lower sides of the two channel steels.

[0009] With the above structure, the hoop rod is welded by channel steel and fixing plate, which not only has a stable structure and can bear large acting forces, but also is convenient to obtain materials for the channel steel, which can reduce the manufacturing cost.

[0010] Reinforcing triangular plates are welded between the vertical plate, the connecting plate and the ear plate.

[0011] With the above structure, the reinforcing triangular plate can improve the connection strength between the vertical plate, the connecting plate and the ear plate, thereby improving the strength of the ear plate and enhancing the stability of the device.

[0012] A tooth groove is provided along the inner edge of the channel steel near the connecting ear. A center plate is connected between the two connecting plates, and the center plate passes through the gap between the two channel steels. Two racks are fixed on the center plate, and the racks are aligned with the tooth grooves at the corresponding positions. A number of threaded holes are provided on the vertical plate, and adjusting bolts are threadedly connected in the threaded holes. The end of the adjusting bolt abuts against the outer side of the channel steel.

[0013] With the above structure, during assembly, the operator can first slide the connecting ear from one end of the channel steel to an appropriate position, and then weld the channel steel. After welding, the connecting ear can move slightly between the two fixing plates, reducing the precision requirements for the position of the connecting ear during assembly and facilitating assembly. Moreover, when connecting to the tower crane, the adjusting bolts can be tightened first, increasing the gap between the vertical plate and the channel steel, and at the same time making the racks engage with the corresponding tooth grooves, which can prevent the connecting ear from sliding on the channel steel. Then, the end of the connecting rod extending from the tower crane is connected to the ear plate. At this time, the connecting rod will block the outer end of the adjusting bolt, preventing the adjusting bolt from loosening and falling off, thereby further enhancing the stability of the device.

[0014] Reinforcing plates are fixed on the inner side wall of the channel steel near the connecting ear, and a number of integrally formed reinforcing ribs are fixed on the reinforcing plates. The upper and lower ends of the reinforcing ribs abut against the inner wall of the channel steel.

[0015] With the above structure, the reinforcing plate can improve the strength of the channel steel, preventing the channel steel from deforming under huge pressure. The reinforcing ribs can prevent the side of the channel steel from deforming, further enhancing the strength of the channel steel.

[0016] A number of positioning plates are fixed below the hoop rod, and a number of positioning holes are provided on the positioning plates.

[0017] With the above structure, after the hoop rod is lifted to an appropriate height, holes are drilled at appropriate positions on the pier, and the hoop rod is connected to the pier through the positioning plates and bolts. The hoop rod mainly bears the lateral tension, and the positioning plates do not need to bear the tension from the tower crane, so the structure is relatively stable.

[0018] Compared with the prior art, the pier hoop for tower crane attachment has the following advantages:

[0019] 1. Through the hoop rod, the welding plate and the connecting ear, the connection between the tower crane and any position on the pier can be achieved, and the connection structure is stable, not affected by the position of the embedded parts. When the embedded parts miss the connection node, it is convenient to attach the tower crane to the wall.

[0020] 2. Through the rack, tooth groove and adjusting bolt, the position of the ear plate can be slightly adjusted when connecting the tower crane, which can reduce the precision requirements during assembly, reduce the installation difficulty, and after connecting with the tower crane, the end of the adjusting bolt is resisted, which can prevent loosening and further improve the stability of the device.

[0021] 3. Through the reinforcing plate and reinforcing rib, the channel steel at the connection position can be strengthened, the strength of the channel steel can be improved, and the channel steel can be prevented from deforming under the action of the tower crane, thereby improving the effect of stabilizing the tower crane.

[0033] Please refer to Figure 1-6 , this embodiment provides a pier hug for tower crane attachment walls, including four hoop rods 1. The ends of the hoop rods 1 are connected with welding plates 2, and the four hoop rods 1 are bolt-connected into a rectangle through the welding plates 2. Two connecting ears 3 are arranged on the hoop rods 1. The connecting ear 3 includes two connecting plates 301 for connecting the hoop rods 1. The two connecting plates 301 are respectively located on the upper and lower sides of the hoop rod 1. A vertical plate 302 is connected to the connecting plate 301. Two symmetrically distributed ear plates 303 are connected to the vertical plate 302, and two connecting holes 304 are provided in the ear plates 303.

[0034] The hoop rod 1 includes two channel steels 101 with opposite openings. A number of equally spaced fixing plates 102 are welded on the upper and lower sides of the two channel steels 101. Welding the channel steels 101 and the fixing plates 102 to form the hoop rod 1 not only has a stable structure and can bear large forces, but also the channel steels 101 are convenient to obtain materials and can reduce the manufacturing cost.

[0035] Reinforcing triangular plates 305 are welded between the vertical plate 302, the connecting plate 301 and the ear plate 303. The reinforcing triangular plates 305 can improve the connection strength between the vertical plate 302, the connecting plate 301 and the ear plate 303, thereby improving the strength of the ear plate 303 and the stability of the device.

[0036] A tooth groove 103 is provided along the inner edge of the channel steel 101 near the connecting ear 3. A center plate 306 is connected between the two connecting plates 301, and the center plate 306 passes through the gap between the two channel steels 101. Two racks 307 are fixed on the center plate 306, and the racks 307 are aligned with the tooth grooves 103 at corresponding positions. A number of threaded holes 308 are provided on the vertical plate 302, and adjusting bolts 309 are threadedly connected in the threaded holes 308. The end of the adjusting bolt 309 abuts against the outer side of the channel steel 101. During assembly, the operator can slide the connecting ear 3 from one end of the channel steel 101 to an appropriate position in advance, and then weld the channel steel 101. After welding, the connecting ear 3 can move slightly between the two fixing plates 102, reducing the precision requirements for the position of the connecting ear 3 during assembly and facilitating assembly. Moreover, when connecting to the tower crane, the adjusting bolt 309 can be tightened first, so that the gap between the vertical plate 302 and the channel steel 101 becomes larger, and at the same time, the rack 307 is stuck at the corresponding position of the tooth groove 103, which can prevent the connecting ear 3 from sliding on the channel steel 101. Then, the end of the connecting rod extending from the tower crane is connected to the ear plate 303. At this time, the connecting rod will block the outer end of the adjusting bolt 309, preventing the adjusting bolt 309 from loosening and falling off, thereby further improving the stability of the device.

[0037] Reinforcing plates 4 are fixed on the inner side wall of the channel steel 101 near the connecting ear 3, and a number of integrally formed reinforcing ribs 401 are fixed on the reinforcing plates 4. The upper and lower ends of the reinforcing ribs 401 abut against the inner wall of the channel steel 101. The reinforcing plates 4 can improve the strength of the channel steel 101 and prevent the channel steel 101 from deforming under huge pressure. The reinforcing ribs 401 can prevent the side of the channel steel 101 from deforming and further improve the strength of the channel steel 101.

[0038] A number of positioning plates 5 are fixed below the hoop rod 1, and a number of positioning holes are provided on the positioning plates 5. After the hoop rod 1 is lifted to an appropriate height, holes are drilled at appropriate positions on the pier, and the hoop rod 1 is connected to the pier through the positioning plates 5 and bolts. The hoop rod 1 mainly bears the lateral tension, and the positioning plates 5 do not need to bear the tension from the tower crane, so the structure is relatively stable.

[0039] In this embodiment, the above fixing methods are all the most commonly used fixed connection methods in the art, such as welding, bolt connection, etc.

[0040] The working principle of the present utility model:

[0041] When assembling, the operator can slide the connecting ear 3 from one end of the channel steel 101 to an appropriate position in advance, and then weld the channel steel 101, the fixing plate 102, and the welding plate 2. After welding, surround the four hoop rods 1 around the outside of the pier, then connect the welding plates 2 through bolts, and then tie one end of the steel cable for lifting to the fixing plate 102. Then, the device can be lifted to an appropriate height through the steel cable, drill holes at appropriate positions on the pier, and connect the hoop rods 1 to the pier through the positioning plate 5 and bolts. The hoop rods 1 mainly bear the lateral tension, and the positioning plate 5 does not need to bear the tension from the tower crane, so the structure is relatively stable. The connecting ear 3 can move slightly between the two fixing plates 102, reducing the precision requirements for the position of the connecting ear 3 during assembly and facilitating assembly. When connecting to the tower crane, the adjusting bolt 309 can be tightened first, making the gap between the vertical plate 302 and the channel steel 101 larger, and at the same time making the rack 307 stuck in the corresponding position of the tooth groove 103, which can prevent the connecting ear 3 from sliding on the channel steel 101. Then, connect the end of the connecting rod extending from the tower crane to the ear plate 303. At this time, the connecting rod will block the outer end of the adjusting bolt 309, preventing the adjusting bolt 309 from loosening and falling off, thereby further improving the stability of the device.

[0042] The above describes the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present patent.
