Description

Technical Field

[0001] The invention relates to the technical field of tower crane equipment, and in particular to an aerial tower crane for tower column construction. Background Art

[0002] Tower cranes, also known as tower cranes, are commonly used lifting equipment on construction sites. Their towers are constructed from standard sections connected by high-strength bolts, allowing them to be raised section by section as construction progresses. During this process, ensuring accurate docking and a secure connection between the upper and lower standard sections is a major concern for those skilled in the art.

[0003] A Chinese patent with publication number CN219058362U discloses a standard section of a tower crane, comprising four parallel main chords, with two adjacent main chords connected by a web member. The main chord is a square tube type, and comprises two first side walls and two second side walls, the two first side walls being arranged opposite to each other, and the two second side walls being also arranged opposite to each other; a second latch hole is provided at the lower end of the first side wall, and a third latch hole is provided at the upper end of the second side wall; two first connecting plates are fixed to the upper end of the main chord, the connecting portion of the first connecting plate is higher than the upper end surface of the main chord, and the first latch holes of the two first connecting plates are coaxial; two second connecting plates are fixed to the lower end of the main chord, the connecting portion of the second connecting plate is lower than the lower end surface of the main chord, and the first latch holes of the two second connecting plates are coaxial.

[0004] When the above patent is in use, the four main chords of the target standard section correspond one to one with the four main chords of the lower standard section, the first pin hole of the second connecting plate of the target standard section will be aligned with the third pin hole of the lower standard section, and the pin will be passed through the first pin hole of the second connecting plate and the third pin hole of the lower standard section; and the second pin hole of the target standard section will be aligned with the first pin hole of the first connecting plate of the lower standard section, and the pin will be passed through the first pin hole of the first connecting plate and the second pin hole of the target standard section, so as to fix the target standard section to the lower standard section.

[0005] Although the above patent uses the first and second connecting plates that are opposite to each other to achieve the alignment and connection between the upper and lower standard sections, since the first and second connecting plates extend beyond the ends of the main chord, they are inevitably bumped and squeezed during the transportation and hoisting of the standard section, causing the first and second connecting plates to deform. Then, when the upper and lower standard sections are docked, the main chord may not be inserted between the two connecting plates due to the deformation of the connecting plates, or after docking, the first pin hole on the connecting plate cannot be aligned with the second and third pin holes on the main chord, resulting in the inability to smoothly install the standard section.

[0006] Therefore, this field needs a kind of tower column construction aerial tower crane to solve the above-mentioned problem. Summary of the Invention

[0007] The present invention provides an aerial tower crane for tower column construction, aiming to solve the problem in the related art that when the standard sections of the tower crane are installed, the connection parts are easily deformed, resulting in the pin holes on the two standard sections being unable to be aligned or even the two standard sections being unable to be successfully connected.

[0008] The present invention provides an aerial tower crane for tower column construction, comprising a tower base, a tower body arranged on the tower base, and a tower arm arranged on the tower body, wherein the tower body comprises a plurality of connected standard sections, each of which comprises two square frames spaced apart from each other and vertical rods connecting the four corners of the two square frames, wherein an inclined web member is connected between two adjacent vertical rods;

[0009] Four reinforcing rods are arranged in the square frame at the bottom. The four reinforcing rods are arranged to form a square. The head end of the reinforcing rod is connected to the standard section, and the head end of the reinforcing rod is located above the tail end of the adjacent reinforcing rod. The head end and tail end of the reinforcing rod are respectively provided with a through hole extending vertically, and the through holes on two adjacent reinforcing rods correspond to each other up and down. The tail end of the reinforcing rod is located below the square frame at the bottom.

[0010] Four supporting plates are provided in the square frame at the top, and the four supporting plates are fixedly connected to the four inner corners of the square frame respectively, and pins are fixedly connected to the supporting plates;

[0011] When the standard section located above is placed on the standard section located below, the tail end of the reinforcing rod rests on the bearing plate, and the pin shaft is inserted into the through hole of the reinforcing rod.

[0012] The present invention configures four reinforcing rods to form a closed square ring support structure. When the standard section encounters lateral wind force, the pin and the reinforcing rod work together to disperse the load borne. Compared with the standard section design that only relies on the pin connection, the stability and reliability of the connection between the standard sections are significantly improved; moreover, since the reinforcing rod has higher strength characteristics, it can resist the risk of deformation during the transportation and lifting operations of the standard section, ensuring smooth docking and installation between the standard sections; in addition, when the upper standard section is placed on the lower standard section, the pin will pass through the preset through hole on the reinforcing rod, and the tail end of the reinforcing rod will be tightly attached to the surface of the bearing plate of the lower standard section. Through the coordinated cooperation of the pin and the reinforcing rod, the relative positions of the upper and lower standard sections in the horizontal direction are locked. Compared with the traditional manual insertion of the pin, this design effectively reduces the amount of manual operation, shortens the time personnel stay on the jacking frame, and thereby reduces the probability of accidents.

[0013] Preferably, the reinforcing rod includes a connecting rod and a connecting block fixedly connected to both ends of the connecting rod, the connecting block forms the head end and the tail end of the reinforcing rod, the through hole is opened on the connecting block, the connecting rod is arranged to be tilted downward from the head end to the tail end, and the connecting block is adapted to the inner corner of the square frame.

[0014] By designing the connecting blocks to match the inner corners of the square frame, the connecting blocks are ensured to fit tightly inside the square frame. When the standard section encounters lateral wind forces, the connecting blocks and the square frame support each other, further enhancing the stability of the connection between the standard sections.

[0015] Preferably, a connection hole 1 is provided on the connection block at the tail end, and a connection hole 2 is provided on the square frame at the top. When the connection block at the tail end of the reinforcing rod rests on the bearing plate of the standard section below, the connection hole 1 and the connection hole 2 are aligned, and high-strength bolts pass through the connection hole 1 and the connection hole 2 to connect the reinforcing rod to the square frame at the top of the standard section below.

[0016] Preferably, the reinforcing rod is elastically connected to the vertical rod through an elastic member, a connecting hole three is provided on the connecting block at the head end, and a connecting hole four is provided on the square frame at the bottom. When the elastic member presses the connecting block at the tail end of the reinforcing rod against the bearing plate of the standard section below, the connecting hole three and the connecting hole four are aligned, and high-strength bolts pass through the connecting hole three and the connecting hole four to connect the reinforcing rod and the square frame where the reinforcing rod is located.

[0017] Through the synergistic effect of high-strength bolts and reinforcing rods, a stable connection is achieved between the upper and lower standard sections, thereby strengthening the stability of the entire tower body, effectively reducing the wear caused by vibration, and significantly improving the structural stability and safety performance under extreme working conditions. This enables the present invention to meet application scenarios with more stringent reliability requirements, such as the field of tower column construction.

[0018] Preferably, the central axis of the connecting hole one and the central axis of the connecting hole three on the two upper and lower adjacent connecting blocks both extend in the horizontal direction, and the central axis of the connecting hole one is perpendicular to the central axis of the connecting hole three.

[0019] It not only facilitates the installation of high-strength bolts, but also allows the connection of high-strength bolts from different directions, further enhancing the stability of the connection between the upper and lower standard sections.

[0020] Preferably, the elastic member includes a connecting member 1, a connecting member 2 and a spring, the connecting member 1 is fixedly mounted on the vertical rod, the connecting member 2 is vertically slidably arranged on the vertical rod, and the connecting member 2 is fixedly connected to the corresponding reinforcing rod, and the spring is connected between the connecting member 1 and the connecting member 2.

[0021] The second connecting piece can slide vertically along the vertical rod. This design ensures the stability of the reinforcing rod during the movement, ensures that the through holes between the stacked reinforcing rods are always accurately aligned up and down, and enables the head end of the reinforcing rod to remain in a position that adapts to the inner corner of the square frame, so that the head end connecting block is in alignment with the inner corner position of the square frame during connection.

[0022] Preferably, a ball is provided at the bottom of the connecting block at the tail end of the reinforcing rod, and a groove adapted to the position of the ball is opened on the supporting plate. When the connecting block is against the supporting plate, the ball is located in the corresponding groove.

[0023] Through the precise fit of the balls and the grooves, when the connecting block is placed on the bearing plate of the standard section below, the balls and the grooves work together to provide guidance for the lowering position of the connecting block and achieve precise limiting.

[0024] Preferably, when the standard section is placed on the ground, the spring is in a contracted state and the ball is in contact with the ground.

[0025] Since standard sections are often large in size and heavy, they are extremely inconvenient to move. However, the ingenious design of the ball bearing allows operators to easily push the standard section to move flexibly on the ground, greatly facilitating the position adjustment and transportation of the standard section.

[0026] Preferably, a mounting rod is fixedly connected between the supporting plates, and a ladder is fixedly mounted on the mounting rod.

[0027] Preferably, the pin shaft is provided with an opening for inserting a cotter pin.

[0028] The beneficial effects of the present invention are as follows: by configuring four reinforcing rods to form a closed square ring support structure, when the standard section encounters lateral wind force, the pins and the reinforcing rods work together to disperse the load borne. Compared with the standard section design that relies solely on the pin connection, the present invention significantly improves the stability and reliability of the connection between the standard sections.

[0029] Moreover, given the high strength of the reinforcing rods, they can resist deformation risks during the transportation and hoisting of the standard sections, ensuring smooth docking and installation of the standard sections.

[0030] In addition, when the upper standard section is placed on the lower standard section, the pin will pass through the preset through hole on the reinforcement rod, and the tail end of the reinforcement rod will be close to the surface of the load-bearing plate of the lower standard section. Through the coordinated cooperation of the pin and the reinforcement rod, the relative positions of the upper and lower standard sections in the horizontal direction are locked. Compared with the traditional manual insertion of pins, this design effectively reduces the amount of manual operation and shortens the time personnel stay on the jacking frame, thereby reducing the probability of accidents.

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figures 1 to 8 As shown, the present invention discloses an aerial tower crane for tower column construction, comprising a tower base 1, a tower body mounted on the tower base 1, and a tower arm 2 mounted on the tower body. The tower body comprises a plurality of connected standard sections 3, a jacking frame 4 mounted on the tower body, and an introduction trolley (not shown) mounted on the jacking frame 4. When a new standard section 3 is to be added to the tower body, the tower arm 2 hoists the standard section 3 onto the introduction trolley. The introduction trolley then places the new standard section 3 into the jacking frame 4, aligning it vertically with the standard section 3 below. The jacking frame 4 is then controlled to move downward, and the new standard section 3 is placed onto the standard section 3 below for connection.

[0043] like Figure 2 and Figure 3 As shown, the standard section 3 includes two square frames 31 spaced apart from each other and vertical rods 32 connecting the four corners of the two square frames 31. An inclined web 33 is connected between two adjacent vertical rods 32. The web 33 between the two vertical rods 32 is connected end to end to form an M shape.

[0044] like Figure 2 、 Figure 5 and Figure 6 As shown, four reinforcing rods 5 are disposed within a square frame 31 at the bottom. The four reinforcing rods 5 are arranged to form a square. The head ends of the reinforcing rods 5 are connected to the standard section 3, and the head ends of the reinforcing rods 5 are positioned above the tail ends of the adjacent reinforcing rods 5, forming a stacked state. Vertically extending through holes 50 are defined at the head and tail ends of the reinforcing rods 5, respectively. The through holes 50 on the head and tail ends of two adjacent reinforcing rods 5 correspond vertically. The tail ends of the reinforcing rods 5 are located below the bottom square frame 31 and are exposed outside the standard section 3.

[0045] like Figure 3 and Figure 4 As shown, four supporting plates 34 are provided in the square frame 31 at the top, and the four supporting plates 34 are fixedly connected to the four inner corners of the square frame 31, and the four supporting plates 34 are fixedly connected to the four supporting plates 34 respectively. A pin shaft 35 extending vertically is fixedly connected, and an opening for inserting a cotter pin is opened on the pin shaft 35 (not shown in the figure).

[0046] like Figure 2 and Figure 8As shown, when the upper standard section 3 is placed on the lower standard section 3, the pin 35 will pass through the through hole 50 on the reinforcing rod 5, and the tail end of the reinforcing rod 5 will rest on the bearing plate 34 of the lower standard section 3. The pin 35 and the reinforcing rod 5 cooperate to fix the relative positions of the upper and lower standard sections 3 in the horizontal direction. Compared with manually inserting the pin 35, the manual participation is reduced, the time that personnel stay on the jacking sleeve 4 is reduced, and the accident rate is reduced; and the reinforcing rod 5 is strong. During the transportation and hoisting of the standard section 3, the reinforcing rod 5 is not easy to deform, which can ensure the smooth docking and installation between the standard sections 3; in addition, by setting the reinforcing rods 5 connected end to end, a closed square ring support structure is formed. When the standard section 3 is subjected to lateral wind force, the pin 35 and the reinforcing rod 5 will disperse the load, which improves the connection stability and reliability between the standard sections 3 compared to the standard sections 3 connected only by the pin 35.

[0047] like Figure 3 and Figure 4 As shown, mounting rods 36 are fixedly connected between the bearing plates 34, and a ladder 37 is fixedly mounted on the mounting rods 36. Since the four reinforcing rods 5 form a square closed loop structure, the space enclosed by the four reinforcing rods 5 does not affect the installation of the ladder 37, and workers can move within the enclosed space, making construction more convenient for workers.

[0048] like Figures 5 to 8 As shown, the reinforcing rod 5 includes a connecting rod 51 and connecting blocks 52 fixedly connected to both ends of the connecting rod 51. The connecting blocks 52 form the head and tail ends of the reinforcing rod 5. Through holes 50 are opened in the connecting blocks 52. The connecting rod 51 is arranged to be tilted downward from the head end to the tail end. The connecting blocks 52 are adapted to the inner corners of the square frame 31. By arranging the connecting blocks 52 to adapt to the inner corners of the square frame 31, the connecting blocks 52 are in contact with the inner side of the square frame 31. When the standard section 3 is subjected to lateral wind force, the connecting blocks 52 and the square frame 31 can offset each other, further ensuring the stability of the connection between the standard sections 3.

[0049] like Figure 3 、 Figure 5 and Figure 8As shown, the reinforcing rod 5 is elastically connected to the vertical rod 32 via an elastic member. A first connection hole 53 is defined in the connecting block 52 at the rear end, a second connection hole 38 is defined in the square frame 31 at the top, a third connection hole 54 is defined in the connecting block 52 at the front end, and a fourth connection hole 39 is defined in the square frame 31 at the bottom. When the elastic member presses the connecting block 52 at the rear end of the reinforcing rod 5 against the bearing plate 34 of the lower standard section 3, the first connection hole 53 and the second connection hole 38 are aligned. High-strength bolts 6 penetrate through the first connection hole 53 and the second connection hole 38 to connect the reinforcing rod 5 to the square frame 31 at the top of the lower standard section 3. The third connection hole 54 and the fourth connection hole 39 are aligned. High-strength bolts 6 penetrate through the third connection hole 54 and the fourth connection hole 39 to connect the reinforcing rod 5 to the square frame 31 where the reinforcing rod 5 is located.

[0050] Since the tail end of the reinforcing rod 5 is located outside the standard section 3, when the standard section 3 is hoisted onto the introduction trolley of the jacking sleeve 4, the reinforcing rod 5 will first contact the introduction trolley. Under the action of the gravity of the standard section 3, the reinforcing rod 5 will move upward relative to the standard section 3, squeezing the elastic member. When the introduction trolley transports the standard section 3 into the jacking sleeve 4, the reinforcing rod 5 contacts the outward platform of the jacking sleeve 4. When the reinforcing rod 5 is out of contact with the outward platform of the jacking sleeve 4, the reinforcing rod 5 abuts against the pin 35 on the lower standard section 3. The elastic force of the elastic member causes the reinforcing rod 5 to have a tendency to pop out downward. In the process of the introduction trolley driving the added standard section 3 to continue to move, the through hole 50 on the reinforcing rod 5 is aligned with the pin 35 on the lower standard section 3. The elastic member causes the reinforcing rod 5 to pop out downward, and the pin 35 enters the through hole 50 of the reinforcing rod 5, thereby realizing automatic alignment and preliminary connection between the upper and lower standard sections 3.

[0051] Afterwards, the jacking sleeve 4 is controlled to descend so that the square frames 31 of the upper and lower standard sections 3 are in contact with each other, and the connecting block 52 at the tail end of the reinforcing rod 5 of the upper standard section 3 rests on the bearing plate 34 of the lower standard section 3. Then, the head end of the reinforcing rod 5 is connected to the standard section 3 where it is located, and the tail end is connected to the lower standard section 3 through the high-strength bolt 6, thereby achieving a stable connection between the upper and lower standard sections 3, increasing the stability of the entire tower body, reducing wear caused by vibration, and significantly improving the structural stability and safety under extreme working conditions, making the present invention suitable for scenarios with extremely high reliability requirements, such as for the construction of tower columns.

[0052] like Figure 5 As shown, the central axis of the connection hole 1 53 and the central axis of the connection hole 3 54 on the two adjacent connection blocks 52 extend horizontally, and the central axis of the connection hole 1 53 is perpendicular to the central axis of the connection hole 3 54. This not only facilitates the installation of the high-strength bolts 6, but also allows the high-strength bolts 6 to be connected from different directions, further enhancing the stability of the connection between the upper and lower standard sections 3.

[0053] like Figure 2 and Figure 5 As shown, the elastic member includes a first connector 7, a second connector 8, and a spring 9. The first connector 7 is fixedly mounted on the vertical rod 32, and the second connector 8 is vertically slidably disposed on the vertical rod 32. The second connector 8 is fixedly connected to the corresponding reinforcing rod 5, and the spring 9 is connected between the first connector 7 and the second connector 8. The second connector 8 slides vertically along the vertical rod 32, ensuring the stability of the reinforcing rod 5 during movement, thereby ensuring that the through holes 50 between the stacked reinforcing rods 5 are always aligned vertically, and the head ends of the reinforcing rods 5 can fit into the inner corners of the square frame 31.

[0054] like Figure 4 、 Figure 6 and Figure 7 As shown, four balls 55 are rotatably connected to the bottom of the connecting block 52 at the rear end of the reinforcing rod 5. The four balls 55 are evenly spaced along the periphery of the through-hole 50. The bearing plate 34 is provided with grooves 341 that match the positions of the balls 55. When the connecting block 52 rests on the bearing plate 34, the balls 55 are positioned within the corresponding grooves 341. Due to the precise fit between the balls 55 and the grooves 341, when the connecting block 52 is placed on the bearing plate 34 of the standard section 3 below, the balls 55 and the grooves 341 work together to guide the lowering position of the connecting block 52 and achieve precise positioning.

[0055] When the standard section 3 is placed on the ground, the spring 9 is in a contracted state and the ball 55 is in contact with the ground. Since the standard section 3 is usually large in size and weight and inconvenient to move, the ball 55 can be provided to push the standard section 3 on the ground, making it convenient to adjust and transport the standard section 3.

[0056] The working principle of an aerial tower crane for tower column construction of the present invention when adding a new standard section 3 is as follows: the tower arm 2 is controlled to hoist the new standard section 3 onto the introduction trolley, and the introduction trolley conveys the new standard section 3 into the jacking sleeve 4. When the reinforcing rod 5 is out of contact with the extended platform of the jacking sleeve 4, the reinforcing rod 5 abuts against the pin 35 on the lower standard section 3. The elastic force of the elastic member causes the reinforcing rod 5 to have a tendency to pop out downward. In the process of the introduction trolley driving the new standard section 3 to continue to move, the through hole 50 on the reinforcing rod 5 is aligned with the pin 35 on the lower standard section 3. The elastic member causes the reinforcing rod 5 to pop out downward, and the pin 35 enters the through hole 50 of the reinforcing rod 5.

[0057] Control the lifting sleeve 4 to move downward until the square frames 31 of the upper and lower standard sections 3 are in contact. The connecting block 52 at the tail end of the reinforcing rod 5 of the new standard section 3 rests on the bearing plate 34 of the lower standard section 3. Pass the high-strength bolt 6 through the connecting hole 1 53 and the connecting hole 2 38 to connect the reinforcing rod 5 to the square frame 31 at the top of the lower standard section 3. Pass the high-strength bolt 6 through the connecting hole 3 54 and the connecting hole 4 39 to connect the reinforcing rod 5 to the square frame 31 where the reinforcing rod 5 is located, thus completing a stable connection between the upper and lower standard sections 3.

[0058] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
