Description

Technical Field

[0001] The invention relates to the field of construction equipment, in particular to a tower crane introduction system and an introduction method thereof. Background Art

[0002] Tower crane is one of the indispensable equipment in high-rise building construction. Due to the construction requirements of different heights, tower cranes will be built at different heights. During the construction of the tower crane, the tower crane beam will be used to lift the standard section to the top of the tower crane, and the standard section will be installed to the top of the tower crane to raise the height of the tower crane, or the reverse operation will be performed to dismantle the tower crane.

[0003] During the installation or disassembly of the standard section, a system needs to be introduced to assist the standard section to enter the tower crane for installation or move out of the tower crane for disassembly. At present, there are two main types of tower crane introduction systems. One is the upper introduction type, in which an introduction beam is set above the installation area of ​​the standard section, and a roller track is provided on the introduction beam. A connecting beam with rollers is connected above the standard section, and then the tower crane crossbeam is used to lift the connecting beam to transport the standard section. During lifting, the connecting beam transports the standard section to the standard section installation area through the crossbeam, and the rollers on the connecting beam are aligned with the roller tracks on the introduction beam for alignment connection, and then the standard section is connected to the introduction beam, and then the connection between the crossbeam and the connecting beam is separated, and finally the standard section is manually moved to the installation position to complete the introduction work; the other is the lower introduction type, in which an introduction beam is set at the lower end of the standard section installation area, and a roller track is provided on the introduction beam. During lifting, the tower crane crossbeam is directly used to transport the standard section to the top of the introduction beam, and then the rollers are installed below the standard section, and then the standard section is placed on the introduction beam, the connection between the standard section and the crossbeam is separated, and the standard section is manually moved to the installation position, and finally disassembled to the rollers to complete the introduction work.

[0004] The upper introduction method has a complex structure. Each time, the connecting beam needs to be hoisted to the ground to connect with the standard section, and then hoisted to the introduction beam for disassembly. At the same time, it is difficult to align the rollers on the connecting beam with the roller tracks on the introduction beam, which makes the introduction work inefficient and labor-intensive.

[0005] In order to avoid the docking operation between the roller and the roller track, the current upper introduction form also uses the connection conversion of the hook structure, such as in the CN201310305542.5 patent, to realize the switching of the suspension relationship between the standard section in the hook and the introduction trolley. However, the structure of the introduction trolley and the auxiliary hook in this patent is very complicated, and there is an overlapping area when the auxiliary hook is connected and converted with the introduction trolley, which easily causes movement interference. In order to avoid interference, it is necessary to reduce the reinforcement structure design of the introduction beam. At the same time, in the case of improper operation, it may also cause collision between the auxiliary hook and the introduction trolley.

[0006] Although the lower introduction method has a simple structure, it requires manual installation and removal of the rollers each time. After the rollers are installed, the rollers and the roller tracks need to be aligned, and it is difficult to remove the rollers, so the lower introduction method still has the problem of low efficiency. In addition, this method directly installs the rollers on the standard sections, so that the rollers of standard sections of different specifications have different spacing after installation, which easily leads to compatibility problems between the rollers and the roller tracks, resulting in poor versatility of this introduction method. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a tower crane introduction system and an introduction method thereof which are simple to operate, safe to introduce and high in introduction efficiency.

[0008] The technical solution adopted by the present invention to solve the above problems is: a tower crane introduction system, including an introduction beam, the introduction beam is horizontally fixed in the standard section installation area of ​​the tower crane, the introduction beam is arranged at the upper end of the installation area, one end of the introduction beam is arranged in the installation area, and the other end of the introduction beam is arranged outside the installation area for receiving the standard section, an introduction trolley is movably connected to the introduction beam, the introduction trolley is provided with rollers, the introduction trolley is also provided with a receiving rod, a double-headed hook is provided on the standard section, the double-headed hook is used to hang the standard section, the double-headed hook has two hooks in total, the two hooks are symmetrically arranged about the central axis of the double-headed hook, and one hook is used to It is connected to the hook on the tower crane, and the other hook is used to be connected to the receiving rod. The receiving rod is used to cooperate with the hook to receive the standard section. A connector is provided between the double-headed hook and the standard section. The double-headed hook is hinged on the connector. The connector and the standard section are connected by a wire rope. When the double-headed hook is connected to the hook, the hanging center of one hook is set on the central axis of the standard section. When the double-headed hook is connected to the hook and converted to being connected to the receiving rod, the connector is always set on the symmetry axis of the standard section, and the center axis of the double-headed hook swings about the connection between the double-headed hook and the connector.

[0009] Compared with the prior art, the advantages of the present invention are: it also adopts the upper introduction form to introduce the standard section, but the introduction trolley with rollers is directly designed on the introduction beam, and then through the design of the double-headed hook and the receiving rod, the crossbeam first uses the double-headed hook to transport the standard section. When the standard section is transported to the introduction beam, the connection of the double-headed hook is converted. After the double-headed hook is connected to the receiving rod, the connection between the double-headed hook and the crossbeam is disengaged to complete the docking of the standard section. This docking method is realized by the connection conversion of the double-headed hook, which is less difficult than the alignment connection between the roller and the roller track, and is very convenient. At the same time, the connection conversion between the hook and the introduction trolley of the standard section does not overlap between the hook and the introduction trolley, and there is no overlap. There is a problem of mobile interference, and there is no need to worry about the hook causing damage to the introduction trolley and the introduction beam during the process of suspending the standard section. At the same time, because the double-headed hook will cause force deflection of the double-headed hook when converting the connection, the design of the connector can transfer the problem of force deflection to the hinge angle of the double-headed hook and the connector, thereby ensuring that the force on the wire rope will not change, ensuring that the force on the wire rope is evenly distributed, and the standard section always remains in a balanced state. Then, through the introduction trolley, the standard section can be manually introduced into the installation area, and then the double-headed hook and the standard section can be separated. There is no need to install and disassemble the roller. Compared with the traditional upper introduction method and the lower introduction method, it has the advantage of high introduction efficiency.

[0010] As an improvement of the present invention, two double-headed hooks are connected to the upper end of a standard section, and the two double-headed hooks are arranged in parallel at the same height. Each of the double-headed hooks is provided with two steel ropes, and the four steel ropes are respectively connected to the four corners of the top of the standard section.

[0011] As an improvement of the present invention, the distance between the two double-headed hooks is smaller than the width of the standard section, and the distance between the four steel ropes increases from the double-headed hooks toward the standard section.

[0012] As an improvement of the present invention, a stop ring is provided on the receiving rod, and the stop ring is used to limit the movement of the double-headed hook on the receiving rod, and one double-headed hook is provided between two stop rings.

[0013] As an improvement of the present invention, an introduction hook is provided between the double-headed hook and the lifting hook, the upper end of the introduction hook is provided with a hook hole for connecting with the lifting hook, and the lower end of the introduction hook is provided with a suspension rod for connecting with the double-headed hook.

[0014] As an improvement of the present invention, a stop ring is also provided on the suspension rod.

[0015] As an improvement of the present invention, two roller tracks parallel to each other are provided on the introduction beam, and the roller tracks are used for the rollers to roll. The roller tracks are I-shaped, and each of the roller tracks is provided with two connected rollers. The two rollers on the same roller track are respectively arranged on both sides of the roller track and are rollingly connected to the roller track.

[0016] The technical solution adopted by the present invention to solve the above problems is: a method for introducing a tower crane introduction system, using a tower crane introduction system, the steps of which are as follows:

[0017] S1: Connect two double-headed hooks on the standard section through a wire rope;

[0018] S2: The hook is lowered to the ground area and connected to one of the hooks of the double-headed hook;

[0019] S3: The hook moves to the lead-in beam with the standard section driven by the crane;

[0020] S4: The connection of the two double-headed hooks is parallel to the receiving rod and the height of the double-headed hooks is slightly higher than the receiving rod of the introduction trolley;

[0021] S5: The hook moves toward the installation area so that the other hook of the double-headed hook is above the receiving rod;

[0022] S6: The hook moves downward, so that the other hook of the double-headed hook is connected to the receiving rod;

[0023] S7: The hook continues to move downward, the double-headed hook is separated from the hook, and the standard section is hung on the receiving rod;

[0024] S8: The hook moves away from the introduction beam, the standard section is moved to the installation area, the wire rope is removed, and the introduction of the standard section is completed.

[0025] Compared with the prior art, the advantages of the present invention are: it also adopts the upper introduction form to introduce the standard section, but the introduction trolley with rollers is directly designed on the introduction beam, and then through the design of the double-headed hook and the receiving rod, first the hook on the crossbeam uses the double-headed hook to transport the standard section, and when the standard section is transported to the introduction beam, the connection of the double-headed hook is converted, and after the double-headed hook is connected to the receiving rod, the connection between the double-headed hook and the crossbeam is disconnected to complete the docking of the standard section. This docking method is realized by the connection conversion of the double-headed hook, which is less difficult than the alignment connection between the roller and the roller track, and is very convenient. Then, through the introduction trolley, the standard section can be manually introduced into the installation area, and then the double-headed hook and the standard section can be separated. In the entire introduction process, the only difficulty is step S4, but the operation difficulty of S4 is much less than the docking of the roller and the roller track in the conventional upper introduction form, and there is no need to install and disassemble the roller like the lower introduction method. Compared with the traditional upper introduction method and the lower introduction method, it has the advantages of high introduction efficiency and reduced operation risks.

[0026] As an improvement of the present invention, in step S1, there is further provided a step of connecting an introduction hook to the hook, and in step S2, the introduction hook is connected to the two double-headed hooks.

[0027] As an improvement of the present invention, a suspension rod is provided on the introduction hook, and two stop rings are provided on the suspension rod to prevent the double-headed hooks from moving apart. Two stop rings are also provided on the receiving rod to prevent the double-headed hooks from moving apart. In step S4, the stop ring on the suspension rod is coplanar with the corresponding stop ring on the receiving rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0038] like Figure 1-5 As shown, a tower crane introduction system includes an introduction beam 1, which is horizontally fixed to the installation area 3 of the standard section 2 of the tower crane. The introduction beam 1 is arranged at the upper end of the installation area 3, one end of the introduction beam 1 is arranged in the installation area 3, and the other end of the introduction beam 1 is arranged outside the installation area 3 for receiving the standard section 2. An introduction trolley 4 is movably connected to the introduction beam 1, and the introduction trolley 4 is provided with a roller 4.1, and the introduction trolley 4 is also provided with a receiving rod 4.2. A double-headed hook 5 is provided on the standard section 2, and the double-headed hook 5 is used to hang the standard section 2. The double-headed hook 5 has two hooks in total, and the two hooks are symmetrically arranged about the central axis of the double-headed hook 5. One hook is used to be connected to the hook on the tower crane, and the other hook is used It is connected to the receiving rod 4.2, and the receiving rod 4.2 is used to cooperate with the hook to receive the standard section 2. A connector 5.1 is provided between the double-headed hook 5 and the standard section 2. The double-headed hook 5 is hinged on the connector 5.1. The connector 5.1 and the standard section 2 are connected by a wire rope 5.2. When the double-headed hook 5 is connected to the hook, the hanging center of one hook is set on the central axis of the standard section 2. When the double-headed hook 5 is connected to the receiving rod 4.2, the hanging center of the other hook is set on the central axis of the standard section 2. When the double-headed hook 5 is connected to the hook and the double-headed hook 5 is connected to the receiving rod 4.2, the connector 5.1 is always set on the symmetry axis of the standard section 2, and the center axis of the double-headed hook 5 swings about the connection between the double-headed hook 5 and the connector 5.1.

[0039] like Figure 5-7As shown, there are two double-headed hooks 5 connected to the upper end of a standard section 2, and the two double-headed hooks 5 are arranged in parallel at the same height. Each of the double-headed hooks 5 is provided with two steel ropes 5.2, and the four steel ropes 5.2 are respectively connected to the four corners of the top of the standard section 2. The distance between the two double-headed hooks 5 is smaller than the width of the standard section 2, and the distance between the four steel ropes 5.2 expands from the double-headed hook 5 toward the standard section 2. A stop ring 6 is provided on the receiving rod 4.2, and the stop ring 6 is used to limit the movement of the double-headed hook 5 on the receiving rod 4.2. A double-headed hook 5 is arranged between two stop rings 6. Because the installation range of the installation area 3 is limited, the installation width of the introduction beam 1 is limited, which in turn causes the installation width of the introduction trolley 4 to be smaller. Correspondingly, the installable spacing between the two double-headed hooks 5 will also be smaller than the width of the standard section 2. However, in order to ensure the stability of the standard section 2 during hoisting, it is still necessary to ensure the connection of the four corners of the top of the standard section 2, so that there will be a hoisting structure in which the distance between the four steel ropes 5.2 expands from the double-headed hook 5 toward the standard section 2. It is easy for the double-headed hook 5 to move along the receiving rod 4.2. Through the design of the stop ring 6, the double-headed hook 5 can be prevented from moving on the receiving rod 4.2, thereby ensuring the stability of the introduction trolley 4 in hoisting the standard section 2.

[0040] like Figure 8 As shown, an introduction hook 7 is provided between the double-headed hook 5 and the lifting hook, and the upper end of the introduction hook 7 is provided with a hook hole 7.1 for connecting with the lifting hook, and the lower end of the introduction hook 7 is provided with a suspension rod 7.2 for connecting with the double-headed hook 5, and a stop ring 6 is also provided on the suspension rod 7.2. Because the hook of the crossbeam may not be suitable for the double-headed hook 5, if the hook diameter of the crossbeam is larger than the hook groove of the double-headed hook 5, the purpose of lifting the standard section 2 cannot be achieved. If the hook diameter of the crossbeam is smaller than the hook groove of the double-headed hook 5, the problem of poor connection stability of the hook in the hook groove will occur. When lifting the standard section 2, the standard section 2 is prone to shaking. Therefore, the connection conversion of the introduction hook 7 is ensured, and the connection stability of the hook and the introduction hook 7 and the connection stability of the introduction hook 7 and the double-headed hook 5 are guaranteed. At the same time, through the design of the introduction hook 7, one hook can be used to lift two double-headed hooks 5, thereby enhancing the stability of the hook lifting the standard section 2. The design of the stop ring 6 on the suspension rod 7.2 has the same function as the design of the stop ring 6 on the receiving rod 4.2, which is to stabilize the double-headed hook 5 on the suspension rod 7.2. At the same time, the stop ring 6 on the suspension rod 7.2 is in the same position as the outer stop ring 6 on the receiving rod 4.2, and the movement directions of the two double-headed hooks 5 are also away from each other, so as to achieve the effect of receiving and positioning. When the two double-headed hooks 5 are transformed from the connection on the suspension rod 7.2 to the connection on the receiving rod 4.2, the distance between the two double-headed hooks 5 will not change, and the stability of the connection transformation is better.

[0041] like Figure 4 、 Figure 5 As shown, the introduction beam 1 is provided with two roller tracks 1.1 parallel to each other, and the roller tracks 1.1 are used for rollers 4.1 to roll. The roller tracks 1.1 are I-shaped, and each roller track 1.1 is provided with two connected rollers 4.1. The two rollers 4.1 on the same roller track 1.1 are respectively arranged on both sides of the roller track 1.1 and are rollingly connected to the roller track 1.1. Compared with the ordinary single-wheel connected roller track 1.1, the I-shaped roller track 1.1 matched with the two rollers 4.1 is The roller track 1.1 has a stronger rolling stability, and when the standard section 2 is moved, the standard section 2 can be prevented from shaking, ensuring that the standard section 2 is safer when moving on the introduction beam 1. At the same time, the matching design of the two rollers 4.1 can make the force applied by the rollers 4.1 to the roller track 1.1 evenly distributed on the roller track 1.1, ensuring the uniformity of the force on the roller track 1.1. During the long-term transportation of the standard section 2, the deformation probability of the roller track 1.1 is reduced, ensuring the service life and safety of the introduction beam 1. In the traditional upper introduction method, if a matching method of one roller track 1.1 corresponding to two rollers 4.1 is adopted, the requirement of simultaneously docking the two roller tracks 1.1 is also faced, and the docking difficulty is extremely high. In the present invention, because there is no need to perform the docking operation between the rollers 4.1 and the roller track 1.1, this connection method can be adopted.

[0042] A method for introducing a tower crane introduction system, wherein the operating steps are as follows:

[0043] S1: Connect the introduction hook 7 to the hook, and connect the two double-headed hooks 5 on the standard section 2 through the wire rope 5.2;

[0044] S2: The hook is lowered to the ground area, so that the introduction hook 7 is connected to one of the two double-headed hooks 5 at the same time;

[0045] S3: The hook is driven by the crane and moves with the standard section 2 to the lead-in beam 1;

[0046] S4: The connection of the two double-headed hooks 5 is parallel to the receiving rod 4.2 and the height of the double-headed hooks 5 is slightly higher than the receiving rod 4.2 of the introduction trolley 4. The stop ring 6 on the suspension rod 7.2 is coplanar with the corresponding stop ring 6 on the receiving rod 4.2;

[0047] S5: The hook moves toward the installation area 3 so that the other hook of the double-headed hook 5 is above the receiving rod 4.2;

[0048] S6: The hook moves downward, so that the other hook of the double-headed hook 5 is connected to the receiving rod 4.2;

[0049] S7: The hook continues to move downward, the double-headed hook 5 is separated from the hook, and the standard section 2 is suspended on the receiving rod 4.2;

[0050] S8: The hook moves away from the introduction beam 1, the standard section 2 is moved to the installation area 3, the wire rope 5.2 is removed, and the introduction of the standard section 2 is completed.

[0051] This introduction method reduces the alignment and connection process between roller 4.1 and roller track 1.1, and eliminates the need for repeated installation and removal of roller 4.1. This significantly reduces the risk of manual overhead work, reduces workload, and improves work efficiency. Furthermore, the suspension operation between the standard section 2 makes the introduction beam 1 more adaptable.

[0052] At the same time, in steps S1 and S2, the design of the introduction hook 7 is added to ensure the stability of the connection between the hook and the double-headed hook 5. In step S4, the design of the stop ring 6 ensures the stability of the connection between the double-headed hook 5 and the standard section 2, which greatly reduces the difficulty of operation in step S4 and makes step S4 easier to successfully align, once again reducing the work intensity of the introduction method and improving work efficiency.

[0053] The above description is merely a description of the preferred embodiment of the present invention and is not to be construed as limiting the scope of the claims. The present invention is not limited to the above embodiment, and variations in the specific structure are permitted. Any variations within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
