Description

Technical Field

[0001] The invention relates to the technical field of equipment hoisting, and in particular to an iron tower installation hoisting device and a hoisting method. Background Art

[0002] The power tower used to erect high-voltage transmission lines is mainly made of multiple sections of steel structure. There are generally two ways to install it: the first is to lay the steel structure horizontally on the ground for assembly, then lift the assembled steel structure tower body and place it vertically, and finally fix it on the foundation; the second is to lift the steel structure layer by layer, from the foundation part upwards to lift the corresponding sections of the steel structure, each section of the steel structure is lifted to the predetermined height by lifting equipment, and then connected to other parts below.

[0003] The boom of a conventional crawler crane is a truss structure. When the height of the tower is too high, the ground space required for the first installation method is large, so the second installation method is more suitable.

[0004] A main boom is installed on the crane body, and an auxiliary boom is detachably installed on the main boom. The auxiliary boom is lifted by a auxiliary boom rope. A front hanger is installed on the auxiliary boom, and the auxiliary boom rope is wound on the front hanger. A jib pulley mechanism is installed on the front hanger, and the jib pulley mechanism includes a fixed right-angle plate, a supporting vertical plate is detachably installed on the fixed right-angle plate, and two groups of supporting vertical plates are arranged opposite to each other, and a rope pulley is rotatably installed between the two groups of supporting vertical plates. In order to prevent the jib rope from moving out of the wheel groove of the jib pulley, the prior art adopts a limiting structure installed on the outer side of the jib pulley to limit the jib rope in the wheel groove of the jib pulley. Please refer to the attached figure for details. Fig.11 Since the space between the limiting structure and the jib pulley is small, the jib hook at one end of the jib rope cannot pass through. Therefore, when installing and disassembling the jib, the jib hook needs to be removed first so that the jib rope can pass between the limiting structure and the jib pulley, and finally the jib hook is installed on the jib rope. The jib rope and the jib hook are installed through a pin shaft and a locking piece. Hammering, tightening and other operations are required during each installation and disassembly process, which will not only delay the construction progress, but also affect the life of the pin shaft and the locking piece. Therefore, a mounting mechanism is needed that can install the jib rope on the jib pulley without disassembling the jib rope and the jib hook. Summary of the invention

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-12 This application is described in further detail.

[0042] The embodiment of the present application discloses a tower installation hoisting device and a hoisting method, including a vehicle body 1, a main boom 2 is installed on the vehicle body 1, a secondary boom 3 is detachably installed on the main boom 2, the secondary boom 3 is hoisted by a secondary boom rope 5, a front hanger 32 is installed on the secondary boom 3, the secondary boom rope 5 is wound on the front hanger 32, a secondary boom pulley mechanism 4 is installed on the front hanger 32, the secondary boom pulley mechanism 4 includes a fixed right-angle plate 41, a support vertical plate 42 is detachably installed on the fixed right-angle plate 41, and two groups of support vertical plates 42 are arranged opposite to each other, a rope pulley 43 is rotatably installed between the two groups of support vertical plates 42, and a support vertical plate 42 is rotatably installed on the support vertical plate 42. A limiting mechanism 6 is installed, and the limiting mechanism 6 includes a flip seat 61, one end of which is rotatably connected to the outer side of the supporting vertical plate 42, and a limiting wheel assembly 62 is provided at the end of the flip seat 61 away from the corresponding supporting vertical plate 42, and the limiting wheel assembly 62 is movably arranged on the outer side of the hanging rope pulley 43; the limiting mechanism 6 also includes a flip seat 2 611, and the flip seat 2 611 and the flip seat 1 61 are respectively installed on two groups of supporting vertical plates 42; when the flip seat 1 61 and the flip seat 2 611 drive the limiting wheel assembly 62 to flip to the outer side away from the hanging rope pulley 43, the auxiliary arm hanging rope 5 passes between the hanging rope pulley 43 and the limiting wheel assembly 62.

[0043] It should be noted that the cross-section of the fixed right-angle plate 41 is L-shaped, and a long through groove is opened on the horizontal plate of the fixed right-angle plate 41. The fixed right-angle plate 41 can be fixed to the front hanger 32 by using bolts to pass through the long through groove. The vertical plate of the fixed right-angle plate 41 is connected to the supporting upright plate 42 by bolts, and the rope pulley 43 is rotatably installed between the two groups of supporting upright plates 42. The flip seat 1 61 is connected to one group of supporting upright plates 42 through the rotating shaft 1, and the flip seat 2 611 is connected to the other group of supporting upright plates 42 through the rotating shaft 2.

[0044] In this embodiment, the implementation scenario is specifically as follows: when installing the jib rope 5, first flip the flip seat 1 61 to drive the limiting wheel assembly 62 away from the rope pulley 43, and stop flipping when the distance between the rope pulley 43 and the limiting wheel assembly 62 increases to the maximum. At this time, the flip seat 1 61 and the flip seat 2 611 are in a vertical state, and the installation space between the rope pulley 43 and the limiting wheel assembly 62 is the largest, which is convenient for the jib rope 5 and the jib hook to directly pass through the installation space. Then, the limiting wheel assembly 62 is put down. At this time, the flip seat 1 61 and the flip seat 2 611 are in a horizontal state. The assembly 62 and the rope pulley 43 clamp the jib rope 5. In order to play a limiting role, the limiting wheel assembly 62 is positioned close to the front end of the rope pulley 43 when clamping the jib rope 5, and the front end is the exit end of the jib rope 5 passing through the installation space. The limiting wheel assembly 62 relies on its own gravity to press on the jib rope 5 in the wheel groove of the rope pulley 43 to prevent the jib rope 5 from escaping from the wheel groove of the rope pulley 43. Through the reversible clamping of the limiting mechanism 6, there is no need to perform hammering, tightening and other operations each time the jib rope 5 is installed and disassembled, thereby avoiding affecting the life of the pin shaft and the locking member and improving the construction efficiency.

[0045] When the jib rope 5 is in a loaded state, the rope pulley 43 plays a supporting role. When the jib rope 5 is in an unloaded state, under the action of inertia, the jib rope 5 can easily lift the limiting wheel assembly 62 away from the rope pulley 43, causing the jib rope 5 to move out of the wheel groove of the rope pulley 43.

[0046] Refer to the instruction manual Figures 5 to 7 In order to solve this problem, the following technical solution is also provided: a limit card plate 63 is rotatably installed on the supporting vertical plate 42, and a bayonet 631 is provided at one end of the limit card plate 63, and one side of the bayonet 631 is open. When the flip seat 1 61 and the flip seat 2 611 are placed horizontally, the flip limit card plate 63 makes one end of the flip seat 1 61 corresponding to the limit wheel assembly 62 abut against the bayonet 631.

[0047] It should be noted that two groups of the limiting clamping plates 63 are arranged corresponding to the flip seat 1 61 , and the opening of the clamping opening 631 corresponds to the direction of the limiting wheel assembly 62 .

[0048] In this embodiment, the implementation scenario is specifically as follows: the limit clamping plate 63 is flipped in the direction close to the limit wheel assembly 62, one end of the pin shaft one and the pin shaft two are respectively inserted into the corresponding bayonet 631, and then the nut is tightened on the pin shaft one and the pin shaft two to limit the position, so that the flip seat one 61 and the flip seat two 611 can be locked in a horizontal state to prevent the auxiliary arm suspension rope 5 from forcibly lifting the limit wheel assembly 62 away from the suspension rope pulley 43.

[0049] The above embodiment requires multiple operations when flipping the limiting wheel assembly 62. When installing the jib rope 5 with a wide jib hook, the installation space provided by lifting the limiting wheel assembly 62 cannot meet the passing conditions of the wide jib hook.

[0050] Refer to the instruction manual Figures 5 to 8 In order to solve this problem, the following technical solution is also provided: the limiting wheel assembly 62 includes a limiting plate 1 621 and a limiting plate 2 622, and the limiting plate 1 621 and the limiting plate 2 622 are detachably connected, the limiting plate 1 621 and one end of the flip seat 1 61 are detachably connected, and the limiting plate 2 622 and one end of the flip seat 2 611 are detachably connected.

[0051] It should be noted that the flip seat 1 61 is connected to the limit plate 1 621 through the pin shaft 1, and the flip seat 2 611 is connected to the limit plate 2 622 through the pin shaft 2.

[0052] Furthermore, a mounting plate 64 is installed at one end of the flip seat 1 61 and the flip seat 2 611, an outer sleeve 641 is installed on the mounting plate 64, and an end of the outer sleeve 641 away from the mounting plate 64 is rotatably connected to a connecting plate 642, and the limit plate 1 621 and the limit plate 2 622 are respectively installed on the corresponding connecting plate 642, and a telescopic column 6411 passes through one end of the outer sleeve 641, and an elastic member 6412 is connected between the telescopic column 6411 and the mounting plate 64.

[0053] It should be noted that one end of the telescopic column 6411 is slidably telescoped inside the outer sleeve 641, so that the limiting plate 1 621 and the limiting plate 2 622 can move horizontally.

[0054] In this embodiment, the implementation scenario is specifically as follows: when the limit plate 1 621 and the limit plate 2 622 move laterally away from each other, one end of the telescopic column 6411 slides and contracts inside the outer sleeve 641, and the installation space is open. At this time, the jib rope 5 can be discharged into the wheel groove of the rope pulley 43 from the opening, and the jib hook does not need to pass through the installation space, so it can be adapted to the jib rope 5 with a large width jib hook.

[0055] When the jib rope 5 slides in the wheel groove of the rope pulley 43, the limit plate 1 621 and the limit plate 2 622 are driven to rotate by friction. Since the limit plate 1 621 and the limit plate 2 622 can be separated laterally, the rotation speeds of the limit plate 1 621 and the limit plate 2 622 are different, which causes loss between the limit plate 1 621 and the limit plate 2 622 due to relative friction.

[0056] Refer to the instruction manual Figures 5 to 11In order to solve this problem, the following technical solution is also provided: a docking block 6211 is provided at the center of the limiting disk 1 621, an extension block 6212 is fixedly provided at the periphery of the docking block 6211, a docking groove 6221 is provided at the center of the limiting disk 2 622, an extension groove 6222 is provided at the periphery of the docking groove 6221, the docking block 6211 enters into the docking groove 6221, and the extension block 6212 enters into the extension groove 6222.

[0057] It should be noted that the connecting plate 642 is rotatably connected to the corresponding telescopic column 6411 , and the limiting plate 1 621 and the limiting plate 2 622 can be synchronously rotated through the adaptation of the extension block 6212 and the extension slot 6222 .

[0058] Since the limiting plate 1 621 and the limiting plate 2 622 can be separated laterally, when the jib rope 5 is moved out of the wheel groove of the rope pulley 43, the limiting plate 1 621 and the limiting plate 2 622 can be separated, causing the limiting wheel assembly 62 to lose the limit on the jib rope 5.

[0059] Refer to the instruction manual Figures 9 to 11 In order to solve this problem, the following technical solution is also provided: a limiting groove 6223 is provided on one side of the extension groove 6222, and the limiting plate 621 is rotated to make the extension block 6212 enter the limiting groove 6223.

[0060] It should be noted that the limiting groove 6223 is communicated with the docking groove 6221 , the limiting groove 6223 is communicated with the extension groove 6222 , and the side surface of the limiting groove 6223 is in a closed state.

[0061] Furthermore, a hoisting mechanism 11 is installed on the vehicle body 1 , and the hoisting mechanism 11 is used to reel in and release the jib rope 5 and the main hoisting device 22 .

[0062] It should be noted that the hoisting mechanism 11 is an existing mature technology.

[0063] Furthermore, a hydraulic mechanism 12 is installed on the vehicle body 1 , the hydraulic mechanism 12 includes a hydraulic cylinder 14 , and an output end of the hydraulic cylinder 14 is rotatably connected to the main boom 2 , and an operating room 13 is installed on the vehicle body 1 .

[0064] It should be noted that the hydraulic mechanism 12 includes a hydraulic oil tank to provide hydraulic oil to the hydraulic cylinder 14, and the operating room 13 is the existing technology.

[0065] Furthermore, a connecting mechanism 21 is installed at one end of the main boom 2, and the auxiliary boom 3 includes a main frame 31. A connecting frame 33 is installed at one end of the main frame 31, and the connecting frame 33 and the connecting mechanism 21 are detachably connected.

[0066] It should be noted that when the auxiliary boom 3 is needed, the auxiliary boom 3 is installed on one end of the main boom 2, and then the connecting mechanism 21 and the connecting frame 33 are fixed by bolts.

[0067] Working principle:

[0068] Flip the flip seat 61 to drive the limiting wheel assembly 62 away from the rope pulley 43. The flipping stops when the distance between the rope pulley 43 and the limiting wheel assembly 62 increases to the maximum. The installation space between the rope pulley 43 and the limiting wheel assembly 62 is the largest, which is convenient for the jib rope 5 and the jib hook to directly pass through the installation space.

[0069] Lower the limiting wheel assembly 62, the limiting wheel assembly 62 and the rope pulley 43 clamp the jib rope 5, and rely on the limiting wheel assembly 62's own gravity to press on the jib rope 5 in the wheel groove of the rope pulley 43 to prevent the jib rope 5 from escaping from the wheel groove of the rope pulley 43.

[0070] The limiting clamping plate 63 is flipped toward the direction close to the limiting wheel assembly 62, and one end of the pin shaft 1 and the pin shaft 2 are respectively inserted into the corresponding bayonet 631, and then tightened on the pin shaft 1 and the pin shaft 2 by nuts to limit the position.

[0071] When the limit plate 1 621 and the limit plate 2 622 move laterally away from each other, one end of the telescopic column 6411 slides and contracts inside the outer sleeve 641, and the installation space is open. At this time, the jib rope 5 can be discharged into the wheel groove of the rope pulley 43 from the open position.

[0072] Refer to the instruction manual Fig.12 The present invention also provides a method for hoisting a tower installation hoisting device, comprising the following steps:

[0073] S1: Install the auxiliary boom 3, move the auxiliary boom 3 to the end of the front hanger 32 and fix it;

[0074] S2: Install the jib rope 5, flip the flip seat 1 61 to drive the limiting wheel assembly 62 away from the rope pulley 43, so that the installation space between the rope pulley 43 and the limiting wheel assembly 62 is maximized, and the jib rope 5 and the jib hook directly pass through the installation space;

[0075] S3: lower the limiting wheel assembly 62, the limiting wheel assembly 62 and the rope pulley 43 clamp the jib rope 5, and rely on the limiting wheel assembly 62's own gravity to press on the jib rope 5 in the wheel groove of the rope pulley 43;

[0076] S4: The limiting clamping plate 63 is flipped toward the limiting wheel assembly 62, and one end of the pin shaft 1 and the pin shaft 2 are respectively inserted into the corresponding bayonet 631, and then tightened on the pin shaft 1 and the pin shaft 2 by nuts to limit the position.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
