DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be interpreted as limiting the present application.

[0030] This application relates to a cable tower construction equipment, see Figures 1 to 6, used to realize the construction of the cable tower 3, which includes a tower crane 1 and a lift 2, wherein the tower crane 1 is used to lift raw materials for construction such as steel bars, formwork, wooden planks, concrete pouring equipment, steel pipes, etc. or to assist other construction equipment in place for the construction of the cable tower 3, and the lift 2 can also be used as a lifting and transportation machinery, which is suitable for the transportation of small batches of goods, and the construction personnel can move to the corresponding cable tower 3 construction position through the lift 2.

[0031] It should also be noted that the cable tower 3 in this embodiment adopts a diamond tower shape of European architectural style, which includes an upper tower column 31, a middle tower column 32 and a lower tower column 33. A plurality of connecting beams (not marked in the figure, the same below) are arranged between the upstream and downstream anchor sections of the upper tower column 31, and the number of connecting beams can be set as needed to stabilize the structure and provide decoration. A middle beam (not marked in the figure, the same below) is arranged between the middle tower column 32 and the upper tower column 31, and a lower beam (not marked in the figure, the same below) is arranged between the lower tower column 33 and the middle tower column 32. The cable tower 3 can form a frame structure by arranging the middle beam and the lower beam, and the lower beam also needs to support the huge reaction force of the vertical support and the horizontal force of the wind-resistant support.

[0032] Please combine Figure 1 and Figure 3 and Figure 4 A wall-attached structure 4 is provided between the tower crane 1 and the cable tower 3 to connect the two. The wall-attached structure 4 includes at least four wall-attached rods 41. One end of the wall-attached rod 41 is fixed to the tower body of the tower crane 1, and the other end is fixed to the cable tower 3. At the same time, the elevator 2 is arranged at the lateral center of the cable tower 3 and is located in the ring structure surrounded by the cable tower 3, the tower crane 1 and the wall-attached rods 41.

[0033] Preferably, four wall attachment rods 41 are provided in this embodiment, and the four wall attachment rods 41 are respectively fixedly connected to the four corner ends of the tower body of the tower crane 1. At the same time, an attachment frame 42 matching the shape of the tower crane 1 is sleeved on the tower crane 1. The end of the wall attachment rod 41 is connected to the attachment frame 42 through a pin 45, and a nut for limiting the relative rotation between the wall attachment rod 41 and the attachment frame 42 is provided on the pin 45. A connection base 43 connected to the cable tower 3 is provided at one end of the wall attachment rod 41 close to the cable tower 3. The wall attachment rod 41 and the connection base 43 are also connected through a pin 45, and a nut that can abut against the connection base 43 is provided on the pin 45. The nut is screwed to abut against the connection base 43 to achieve the fixing of the wall attachment rod 41 and the connection base 43. At the same time, the nut can be reversely loosened to facilitate the adjustment of the fixing angle of the wall attachment rod 41.

[0034] Furthermore, the connection base 43 is also provided with anchor bars 44 extending into the cable tower 3, and the cable tower 3 can be connected by the anchor bars 44 so that the connection base 43 and the cable tower 3 work together to bear various stresses, and the four wall-attached rods 41 should be kept in the same horizontal plane as much as possible. In addition, when the wall-attached structure 4 interferes with the structure at the corresponding connection position of the tower crane 1, the installation height of the attachment frame 42 can be appropriately raised or lowered, and the height difference between the attachment frame 42 and the connection base 43 can be allowed to be no more than 200 mm.

[0035] Since the middle tower column 32 of the cable tower 3 extends obliquely toward its vertical center line, and the position of the tower crane 1 remains unchanged, the distance between the cable tower 3 and the tower crane 1 increases with the increase of height, and the length of the wall attaching rod 41 can be changed with the change of the distance between the cable tower 3 and the tower crane 1, and since the wall attaching rod 41 and the connecting base 43 are connected by a pin shaft 45 and fixed with a nut, the relative angle between the wall attaching rod 41 and the connecting base 43 can be adjusted by loosening the nut, thereby achieving the purpose of adjusting the fixed angle of the wall attaching rod 41, and at the same time, the relative angle between the wall attaching rod 41 and the attachment frame 42 is adjustable, so that the wall attaching rod 41 can be suitable for installation in different positions.

[0036] When installing the attachment structure, the verticality of the tower axis of the cable tower 3 should be checked with a total station. The deviation should not be greater than 4 / 1000 of the total height of the tower. When deviation occurs, the length of the wall attachment rod 41 can be adjusted. The distance between the elevator 2 located in the ring structure formed by the cable tower 3, the tower crane 1 and the wall attachment rod 41 and the wall attachment rods 41 on both sides should be greater than 1m to ensure that there is enough space for the construction of the elevator 2. Figure 3 The distance between the elevator 2 and the wall-attached rods 41 on both sides thereof is preferably 1.5 m, and the guide rail 21 of the elevator 2 is 1 m away from the cable tower 3, and an attachment frame 212 is arranged between the two to provide support for the guide rail 21 of the elevator 2.

[0037] In addition, since the side of the upper tower column 31 is narrow, the space reserved for the elevator 2 when the wall-attached rod 41 is directly connected to the upper tower column is small, resulting in the elevator 2 being unable to operate normally or the need to extend the distance between the elevator 2 and the cable tower 3. In this case, a wall-attached frame 46 can be provided between the wall-attached rod 41 and the cable tower 3, and the wall-attached frame 46 is fixedly connected to the side of the upper tower column 31, so that the elevator 2 can be moved from the ring formed by the wall-attached frame 46 and the upper tower column 31. The wall-mounted frame 46 passes through the structure, and one end of the wall-mounted frame 46 close to the wall-mounted rod 41 is provided with a connecting base 43 for connecting the wall-mounted rod 41. The wall-mounted rod 41 connects the wall-mounted frame 46 and the tower crane 1 to achieve the connection between the tower crane 1 and the cable tower 3. By adding the wall-mounted frame 46, the conflict between the wall-mounted structure 4 and the elevator 2 can be avoided. At the same time, the length of the wall-mounted rod 41 can be shortened to avoid the structure formed by the wall-mounted rod 41 being too narrow and long, thereby causing instability of the overall structure.

[0038] For details, please combine Figure 6 The wall-attaching frame 46 includes two groups of first wall-attaching rods (not shown in the figure, the same below) and second wall-attaching rods and first wall-attaching rods (not shown in the figure, the same below) arranged in parallel, one of the first wall-attaching rods of one group is arranged horizontally and one end of which is fixed to the upper tower column, and an anchor bar 44 embedded in the upper tower column 31 is provided at the end, the other end of the first wall-attaching rod is fixed to the second wall-attaching rod, the second wall-attaching rod is arranged obliquely, and the end of the second wall-attaching rod away from the first wall-attaching rod extends toward the upper tower column 31 and is fixed, and an anchor bar 44 embedded in the upper tower column 31 is also provided at the end, and a fixing rod (not shown in the figure, the same below) for connecting the two groups of first wall-attaching rods and second wall-attaching rods is provided between the two groups, so that a triangular truss structure can be formed, and a connecting base 43 connected to the wall-attaching rod 41 is arranged at the connecting position of the first wall-attaching rod and the second wall-attaching rod, and the elevator 2 can pass through the annular structure enclosed by the wall-attaching frame 46 and the upper tower column 31. Preferably, the wall-mounted frame 46 in this embodiment is constructed of square steel pipes.

[0039] In addition, the tower crane 1 of this embodiment needs to be continuously raised as the cable tower 3 is erected. The specific raising method adopts the jacking and sectioning method. As the tower crane 1 is continuously raised, the wall-attached structure 4 should be installed at the same time, and the verticality of the tower crane 1 should be checked. The construction personnel must be aware of the installation spacing of the wall-attached structure 4 and the requirements for the maximum free end height of the tower crane 1, and use a theodolite to check the verticality of the tower axis of the tower crane 1, requiring the verticality deviation of the tower body below the attachment to be no more than 1 / 1000. In addition, the wall-attached structure 4 can be set in multiple groups according to the actual construction needs to ensure the attachment stability of the tower crane 1. At the same time, during the operation of the tower crane 1, it should also be checked whether the wall-attached structure 4 is loose, and timely adjustments should be made.

[0040] In this embodiment, please combine Figure 1 and Figure 2 The elevator 2 is provided with three units, including two inclined single-cage elevators 2001 and one vertical single-cage elevator 2002, wherein the two inclined single-cage elevators 2001 are respectively arranged at the lateral center positions of the left and right tower limbs of the middle tower column 32, and the vertical single-cage elevator 2002 is arranged at the left tower limb of the upper tower column 31, and the cable tower 3 is provided with a transition platform 5 located at the middle cross beam for facilitating the construction workers to transition between the inclined single-cage elevator 2001 and the vertical single-cage elevator 2002, and the transition platform 5 can be used as the foundation of the elevator 2.

[0041] The inclined single-cage elevator 2001 and the vertical single-cage elevator 2002 both include a guide rail 21, a cage 22 moving on the guide rail 21, and a driving device 23 for driving the cage 22 to move along the length direction of the guide rail 21. The guide rail 21 of the inclined single-cage elevator 2001 is defined as a first guide rail, which extends along the inclination direction of the middle tower column 32 and is fixedly connected to the middle tower column 32 through an attachment frame 212, and the inclination angle of the first guide rail is adapted to the inclination of the middle tower column 32; the guide rail 21 of the vertical single-cage elevator 2002 is defined as a second guide rail, which is arranged in the vertical direction, and is fixedly connected to the upper tower column 31 through the attachment frame 212.

[0042] The above-mentioned transition platform 5 is arranged at the ends of the first track and the second track, and the ends of the first track and the second track are fixed by the transition platform 5. At the same time, the transition platform 5 is docked with the entrance and exit of the cage 22 of the elevator 2 to facilitate construction personnel to enter and exit the cage 22 through the transition platform 5.

[0043] The transition platform 5 includes a supporting structure 51, an embedded structure 52 and a steel plate 53 laid on the supporting structure 51 to form a platform, wherein the embedded structure 52 is embedded in the cable tower 3, and the supporting structure 51 includes a plurality of horizontal support rods (not shown in the figure, the same below) located in the same horizontal plane and a plurality of inclined support rods (not shown in the figure, the same below) arranged one by one corresponding to the horizontal support rods, the ends of the horizontal support rods are connected to the embedded structure 52, and the inclined support rods extend from the free ends of the horizontal support rods toward the cable tower 3 and are connected to the embedded structure 52. The embedded structure 52 is provided with a plurality of end portions corresponding to the end portions of the supporting structure 51 connected to the cable tower 3, so that the supporting structure 51 can constitute a triangular support frame and under the support of the embedded structure 52, the transition platform 5 can be stably cantilevered on the cable tower 3.

[0044] In addition, the transition platform 5 also includes a guardrail 54 arranged on the outer periphery of the steel plate 53 to prevent construction workers from falling from the transition platform 5. A protective shed 55 for preventing falling injuries is also provided above the steel plate 53, thereby improving the safety factor of construction workers' construction operations.

[0045] Preferably, the first guide rail and the second guide rail in the present embodiment are both spliced ​​with standard sections 211 of 650×650×1508 mm, and two adjacent standard sections 211 can be fixed by bolts. At the same time, the attachment frames 212 of the first guide rail and the second guide rail are both made of type II standard rods, and the attachment frames 212 of the first guide rail are arranged in multiple groups and are arranged at intervals of 6-9 m, and the attachment frames 212 of the second guide rail are arranged in multiple groups and are arranged at intervals of 4.8-5.5 m. In addition, since the second guide rail is adapted to the angle change of the middle tower column 32, the angle is adjusted by installing adjustment pads (not shown in the figure, the same below) between its standard sections 211.

[0046] Please combine Figure 2 The cage 22 is in a rectangular shape and its side is connected to a guide frame 224 that cooperates with the corresponding guide rail 21. The cage 22 is arranged in a vertical direction, wherein the cage 22 on the first guide rail is arranged at an angle to the first guide rail, and the guide frame 224 is arranged at an angle to the cage 22.

[0047] Specifically, the bottom of the guide frame 224 is connected to the bottom of the cage 22, and a connecting rod 225 connecting the top of the cage 22 and the guide frame 224 is provided, so that the cage 22, the guide frame 224 and the connecting rod 225 can form a stable triangular structure, and at the same time, a safety limit roller (not marked in the figure, the same below) cooperating with the first guide rail is provided on the guide frame 224. The cage 22 moves along the first guide rail under the drive of the driving device 23, and the guide frame 224 cooperates with the first guide rail to guide and limit the cage 22, and can also limit the cage 22 from being separated from the guide rail 21, so as to improve the stability of the operation of the hoist wheel 22.

[0048] In addition, in the present embodiment, the bottom of the cage 22 is preferably made of patterned aluminum plate, and its side is provided with a cage door 221 for construction workers to enter and exit the cage 22, and the cage door 221 is provided on the side of the cage 22 that can be docked with the transition platform 5 to facilitate construction workers to go up and down. Preferably, the cage door 221 is made of perforated aluminum plate, and the remaining sides of the cage 22 are made of aluminum plate or wire mesh, so as to reduce the weight of the cage 22 and then reduce the burden on the elevator 2.

[0049] The top of the cage 22 is designed with a steel structure, and any 0.4m2 area on the top of the cage 22 can withstand a load of 1500N, and any point can withstand a load of 500N. In addition, a trap door 222 is provided on the top of the cage 22, and a ladder (not shown in the figure, the same below) is provided inside the cage 22 for construction workers to pass through the trap door 222 to the top of the cage 22. A suspension rod (not shown in the figure, the same below) is also installed on the top of the cage 22, and construction workers can install and remove the standard section 211 and other components of the guide rail 21 by themselves through the suspension rod. In order to improve the safety factor of construction workers, a safety fence 223 is set on the top of the cage 22, and safety switches are provided on the single and double doors of the cage 22, and mechanical interlocks and electrical interlocks are provided on the cage door 221 and the safety fence 223. When the cage door 221 or the trap door 222 is opened or not closed, the driving device 23 cannot be started, and the cage 22 cannot operate at this time.

[0050] At the same time, the elevator 2 is also equipped with a normally closed brake (not shown in the figure, the same below) and an overload protection device (not shown in the figure, the same below). When an abnormal situation occurs in the elevator 2, the normally closed brake can directly cut off the power supply of the elevator 2, so that the elevator 2 stops running and remains stable. In addition, when overloaded, the alarm installed on the cage 22 will sound, and the elevator 2 cannot be started at this time. Only when the elevator 2 returns to normal can the elevator 2 run normally.

[0051] A buffer 226 is provided at the bottom of the cage 22. When the elevator 2 moves downward, the buffer 226 is compressed, thereby reducing the impact on the cage 22, so that the cage 22 can be braked smoothly. The cage 22 is also provided with upper and lower limit switches (not shown in the figure, the same below) and an extreme switch (not shown in the figure, the same below). When the cage 22 runs to the upper and lower terminal points of the guide rail 21 corresponding to it, it can automatically stop running. If it cannot stop beyond the safety distance for some reason at this time, the extreme switch will actively cut off the main power supply to brake the cage 22.

[0052] An operating table (not shown in the figure, the same below) is also provided in the cage 22 to facilitate construction personnel to control the operation of the elevator 2, and a lighting device (not shown in the figure, the same below) is provided in the cage 22 to ensure the light intensity in the cage 22, so that construction personnel can operate the elevator 2 through the slot of the operating table when the light is dim.

[0053] Please combine Figure 2 The driving device 23 includes a rack 231 arranged on the guide rail 21 and a gear reducer 232 arranged on the cage 22 and meshing with the rack 231. The gear reducer 232 is specifically composed of a gear meshing with the rack 231 and a reducer for controlling the speed of the gear. Specifically, the rack 231 extends along the length direction of the guide rail 21, and the gear reducer 232 is arranged on a guide frame 224 connected to the cage 22. At the same time, a motor for driving the gear reducer 232 to rotate is provided on the guide frame 224 (not shown in the figure, the same below). Since the rack 231 is fixed on the guide rail 21, when the gear reducer 232 rotates under the drive of the motor and the meshing action of the rack 231, it can move along the rack 231, and then drive the cage 22 to rise and fall along the rack 231.

[0054] In other embodiments, the cage 22 can be pulled by a steel rope and a winch, and the winch is arranged on the transition platform 5 at the top of the guide rail 21. One end of the steel rope is fixed to the cage 22, and the other end can be reeled or extended by the winch, so that the cage 22 moves along the guide rail 21 under the traction of the steel rope.

[0055] Since the cage 22 needs to constantly change its position, and the cage 22 needs to obtain power at any time in different positions, otherwise it will not be able to continue moving, the cable tower construction equipment is equipped with a busbar system (not shown in the figure, the same below) to provide a power source for the movement of the cage 22. The busbar system includes a cable (not shown in the figure, the same below) and a transmission trolley (not shown in the figure, the same below). The end of the cable connected to the cage 22 is connected to the transmission trolley, and the transmission trolley moves on the guide rail 21 and is connected to the cage 22, so that the transmission trolley moves with the rise and fall of the cage 22 to drive the cable.

[0056] Furthermore, a cable protection frame (not shown in the figure, the same below) is also provided on the guide rail 21. The cable protection frame extends along the length direction of the guide rail 21, and the cable protection frame is U-shaped, so that the cable can be placed in the cable protection frame to ensure that when the wind load is large, the cable cannot deviate from the running path of the transmission trolley, so that the cage 22 can operate normally.

[0057] Before installing the elevator 2, it should be ensured that the installation site has sufficient power supply and sufficient materials. After the spare parts are completed, the construction personnel must be familiar with the installation safety requirements and set up the basic platform (i.e., transition platform 5) of the elevator 2 at the corresponding position of the cable tower 3. The installation of the elevator 2 first requires cleaning the surface of the basic platform, installing the chassis and leveling it with a level ruler, tightening the anchor bolts, and then installing the standard section 211 of the guide rail 21. The hoist cage 22 with the lower slow-action spring installed is hoisted into place using a lifting device, wherein the meshing side clearance between the gear reducer 232 of the hoist cage 22 and the rack 231 on the guide rail 21 should be maintained at 0.2-0.5mm, the clearance between the safety limit roller and the inner surface of the rack 231 is 0.5mm, and the clearance between the safety limit roller and the riser of the standard section 211 of the guide rail 21 is 0.5mm. Then use the lifting equipment to lift the transmission trolley and put it in place from above the standard section 211 of the guide rail 21, connect and fix the transmission trolley to the cage 22, adjust the door lock, and all doors should be flexible to open and close.

[0058] When installing the standard section 211 of the guide rail 21, use a level or plumb line to measure the verticality of the guide rail 21, and protect the verticality of each vertical pipe of the guide rail 21 in two adjacent directions ≤1 / 1500. If the verticality needs to be adjusted, different thickness adjustment steel plates can be inserted between the chassis and the foundation platform at the anchor bolts. When the guide rail 21 is adjusted to vertical, tighten the four anchor bolts with a torque of 350N·m. Use the same method to adjust the verticality of the cage door 221, so that the verticality of the cage door 221 in two adjacent directions is ≤1 / 1000.

[0059] Since the running distance of the elevator 2 increases with the erection of the cable tower 3, the subsequent raising of the guide rail 21 may specifically include the following steps: first, clean the pipe joints at both ends of the standard section 211 of the guide rail 21 and the pins of the rack 231, and add a small amount of grease; the construction personnel climb the ladder in the cage 22 through the trap door 222 to the top of the cage 22, and then hook the standard section 211 hoisting device through the hanging rod set at the top of the cage 22 and hang the standard section 211 to the top of the cage 22, close the trap door 222, and start the elevator 2. When the cage 22 rises to near the top of the guide rail 21, it should be driven in a jog manner until it is about 300mm close to the top of the installed guide rail 21; lift the standard section 211 with the hanging rod, align the hook with the pin holes on the lower standard section 211 riser and the rack 231, and then tighten it with bolts.

[0060] According to the above method, the standard sections 211 are connected in sequence until the required height is reached. As the guide rail 21 is continuously raised, the attachment frame 212 should be installed at the same time, and the installation verticality (inclination) of the guide rail 21 should be checked. The construction personnel must be clear about the installation spacing of the attachment frame 212 and the requirements for the maximum free end height of the guide rail 21. At the same time, the connection requirements and adjustment methods of the various parts of the attachment frame 212 to be installed must be mastered. After each attachment frame 212 is installed, the installation verticality (inclination) of the guide rail 21 must be checked, and the attachment frame 212 is used to correct the deviation that exceeds the allowable range.

[0061] In the cable tower construction equipment of the present application, the elevator 2 is arranged in the annular space formed by the cable tower 3, the tower crane 1 and the attached structure to reduce the interference between the elevator 2 and the tower crane 1, and the position of the elevator 2 is not limited by the distance between the cable tower 3 and the tower crane 1, and the distance between the elevator 2 and the cable tower 3 can be reduced to shorten the length of the guide rail 21 of the elevator 2 attached to the wall, thereby reducing the safety risk, and can overcome the problem of limited foundation fixing surface of the cable tower 3 pedestal or the surrounding of the pedestal, and the elevator 2, the tower crane 1 and the cable tower 3 are compactly arranged, which is conducive to making full use of the foundation fixing surface and avoiding obstruction of the waterway. At the same time, the elevator 2 can be installed and disassembled using the tower crane 1, which can reduce the conflict between the elevator 2 and the tower crane 1.

[0062] In addition, by setting a transition platform 5 between the inclined single-cage elevator 2001 and the vertical single-cage elevator 2002, it is convenient for construction workers to go up and down, thereby reducing the risk factor for construction workers when switching between the two elevators 2 and improving construction efficiency.

[0063] In addition, the method for completing the construction of the cable tower 3 by the cable tower construction equipment of the present application specifically includes the following steps:

[0064] First, it is necessary to complete the pre-embedded foundation of cable tower 3 and the pouring of the main load-bearing platform of cable tower 3, and then the foundation of tower crane 1 is pre-embedded on both sides of the main load-bearing platform of cable tower 3. Then, the cable tower 3 to be constructed is divided into 41 sections. When dividing the cable tower 3 into sections, it is necessary to comprehensively consider the bearing capacity of the pier and the lower tower column 33. At the same time, tower crane 1 is set up on the pre-embedded foundation of tower crane 1 for use by cable tower 3.

[0065] The cable tower construction can be carried out in conjunction with the formwork system. The construction workers first install the formwork on the main load-bearing platform and fix the formwork and the main load-bearing platform with anchor bolts, and then pour concrete. After the concrete solidifies, the upper surface of the concrete of the segment is cleared, and then the tower crane 1 is used to lift the formwork of the next segment to the completed concrete segment. The construction workers can set up a ladder to move to the corresponding position to tie the steel bars of the formwork and the completed concrete segment formwork, and embed the specified formwork, and then pour the concrete of the segment.

[0066] After the cable tower 3 reaches a certain height, it is necessary to build an elevator 2 and a wall structure 4 on the cable tower 3. The elevator 2 can facilitate construction workers to move to the corresponding cable tower 3 construction position through the elevator 2. The wall structure 4 can improve the stability of the tower crane. The elevator 2 is located in an annular structure formed by the cable tower 3, the tower crane 1 and the wall structure 4, which can reduce the occupation of the waterway by the elevator 2.

[0067] The present application adopts a construction method of a cable tower 3 construction equipment, which divides the tower column into multiple sections, and casts the sections one by one, and cooperates with a tower crane 1, a lift 2 and a formwork system to tie steel bars and cast the steel bars. The construction process is simple and the processing efficiency is high.

[0068] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
