Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of equipment hoisting, in particular to a tower installation hoisting device and a hoisting method. BACKGROUND

[0002] The power tower for erecting high-voltage transmission lines is mainly made of multiple sections of steel structure. When installing, there are generally two ways: the first way is to lay the steel structure horizontally on the ground for assembly, then hoist the assembled steel tower body vertically, and finally fix it on the foundation; the second way is to hoist and install the steel structure layer by layer from the foundation, and sequentially hoist the corresponding section of steel structure upwards. Each section of steel structure is hoisted to a predetermined height position by a hoisting device, and then connected with other parts below.

[0003] The hoisting arm of the conventional crawler crane is a truss structure. When the height of the tower is too high, the first installation method requires a larger ground space, so the second installation method is more suitable.

[0004] A main hoisting arm is installed on the crane body, and a secondary hoisting arm is detachably installed on the main hoisting arm. The secondary hoisting arm performs hoisting work through a secondary arm hoisting rope. A front hoisting frame is installed on the secondary hoisting arm, and the secondary arm hoisting rope is wound on the front hoisting frame. A secondary arm pulley mechanism is installed on the front hoisting frame. The secondary arm pulley mechanism includes a fixed right-angle plate, and two groups of support vertical plates are detachably installed on the fixed right-angle plate. A hoisting rope pulley is rotatably installed between the two groups of support vertical plates. In order to prevent the secondary arm hoisting rope from moving out of the wheel groove of the secondary arm pulley, the prior art adopts a limiting structure installed on the outer side of the secondary arm pulley to limit the secondary arm hoisting rope in the wheel groove of the secondary arm pulley. For reference, see Figure 1 of the prior art. Figure 11 Because the space between the limiting structure and the secondary arm pulley is small, the secondary arm hook at one end of the secondary arm hoisting rope cannot pass through. Therefore, when installing and disassembling the secondary arm, the secondary arm hook needs to be removed first, so that the secondary arm hoisting rope can pass between the limiting structure and the secondary arm pulley. Finally, the secondary arm hook is installed on the secondary arm hoisting rope. The secondary arm hoisting rope and the secondary arm hook are installed through a pin shaft and cooperated with a locking piece. During each installation and disassembly process, hammering and tightening operations are required, which not only delays the construction progress, but also affects the service life of the pin shaft and the locking piece. Therefore, an installation mechanism is needed that can install the secondary arm hoisting rope on the secondary arm pulley without disassembling the secondary arm hoisting rope and the secondary arm hook.

[0043] It should be noted that the cross section of the fixed right-angle plate 41 is L-shaped, a long through groove is formed in the horizontal plate of the fixed right-angle plate 41, a bolt is used to pass through the long through groove, the fixed right-angle plate 41 is fixed on the front hoisting frame 32, the vertical plate of the fixed right-angle plate 41 is connected with the supporting vertical plate 42 through a bolt, the hoisting rope pulley 43 is rotatably installed between the two groups of supporting vertical plates 42, the turnover seat one 61 is connected with one group of supporting vertical plates 42 through a rotating shaft one, and the turnover seat two 611 is connected with the other group of supporting vertical plates 42 through a rotating shaft two.

[0044] In the embodiment, the implementation scene is specifically as follows: when installing the auxiliary arm hoisting rope 5, first turn over the first turnover seat 61 to drive the limiting wheel assembly 62 away from the hoisting rope pulley 43, stop turning over when the distance between the hoisting rope pulley 43 and the limiting wheel assembly 62 is increased to the maximum, at this time, the first turnover seat 61 and the second turnover seat 611 are in the vertical state, the installation space between the hoisting rope pulley 43 and the limiting wheel assembly 62 is the largest, the auxiliary arm hoisting rope 5 and the auxiliary arm hook can directly pass through the installation space, then put down the limiting wheel assembly 62, at this time, the first turnover seat 61 and the second turnover seat 611 are in the horizontal state, the limiting wheel assembly 62 and the hoisting rope pulley 43 clamp the auxiliary arm hoisting rope 5, in order to play a limiting role, when the limiting wheel assembly 62 clamps the auxiliary arm hoisting rope 5, the position of the limiting wheel assembly 62 is close to the front end of the hoisting rope pulley 43, the front end is the outlet end of the auxiliary arm hoisting rope 5 passing through the installation space, the auxiliary arm hoisting rope 5 is pressed on the wheel groove of the hoisting rope pulley 43 by the gravity of the limiting wheel assembly 62 itself, so that the auxiliary arm hoisting rope 5 is prevented from being separated from the wheel groove of the hoisting rope pulley 43, through the turnable clamping of the limiting mechanism 6, no hammering, tightening and other operations are needed when installing and disassembling the auxiliary arm hoisting rope 5 each time, the service life of the pin shaft and the locking piece is avoided from being affected, and the construction efficiency is improved.

[0045] When the auxiliary arm hoisting rope 5 is in the loaded state, the hoisting rope pulley 43 plays a supporting role, when the auxiliary arm hoisting rope 5 is in the unloaded state, under the action of inertia, the auxiliary arm hoisting rope 5 is easy to lift the limiting wheel assembly 62 to make it away from the hoisting rope pulley 43, so that the auxiliary arm hoisting rope 5 is moved out of the wheel groove of the hoisting rope pulley 43.

[0046] Referring to the drawings accompanying the specification Figures 5 to 7 , in order to solve the problem, the following technical scheme is also provided: a limiting clamping plate 63 is rotatably installed on the supporting vertical plate 42, one end of the limiting clamping plate 63 is provided with a clamping opening 631, one side of the clamping opening 631 is provided in an open manner, when the first turnover seat 61 and the second turnover seat 611 are horizontally placed, the limiting clamping plate 63 is turned over to make one end of the first turnover seat 61 corresponding to the limiting wheel assembly 62 abut against the clamping opening 631.

[0047] It should be noted that the limiting clamping plate 63 is provided with two groups corresponding to the first turnover seat 61, and the opening of the clamping opening 631 corresponds to the direction of the limiting wheel assembly 62.

[0048] In the embodiment, the implementation scene is specifically as follows: the limiting clamping plate 63 is turned over in the direction close to the limiting wheel assembly 62, one end of the pin shaft one and the pin shaft two is clamped into the inside of the corresponding clamping opening 631, and then the limiting is performed on the pin shaft one and the pin shaft two by tightening the nut, so that the first turnover seat 61 and the second turnover seat 611 can be locked in the horizontal state, and the auxiliary arm hoisting rope 5 is prevented from forcibly lifting the limiting wheel assembly 62 away from the hoisting rope pulley 43.

[0049] The above embodiment needs multiple operation actions when overturning the limiting wheel assembly 62, and the installation space provided by lifting the limiting wheel assembly 62 cannot meet the passing condition of the large-width auxiliary arm hook when installing the auxiliary arm rope 5 with the large-width auxiliary arm hook.

[0050] With reference to the drawings Figures 5 to 8 In order to solve the problem, the following technical scheme is further provided: the limiting wheel assembly 62 comprises a limiting disc one 621 and a limiting disc two 622, and the limiting disc one 621 and the limiting disc two 622 are detachably connected, the limiting disc one 621 is detachably connected with one end of the overturning seat one 61, and the limiting disc two 622 is detachably connected with one end of the overturning seat two 611.

[0051] It should be noted that the overturning seat one 61 connects the limiting disc one 621 through a pin shaft one, and the overturning seat two 611 connects the limiting disc two 622 through a pin shaft two.

[0052] Further, one end of the overturning seat one 61 and the overturning seat two 611 is provided with a mounting plate 64, the mounting plate 64 is provided with an outer sleeve 641, one end of the outer sleeve 641 away from the mounting plate 64 is rotatably connected with a connecting disc 642, the limiting disc one 621 and the limiting disc two 622 are respectively installed on the corresponding connecting disc 642, one end of the outer sleeve 641 penetrates through an extension column 6411, and the extension column 6411 is connected with the mounting plate 64 through an elastic element 6412.

[0053] It should be noted that one end of the extension column 6411 is slidingly and telescopically arranged in the outer sleeve 641, so that the limiting disc one 621 and the limiting disc two 622 can move transversely.

[0054] In the embodiment, the implementation scenario is specifically that when the limiting disc one 621 and the limiting disc two 622 move transversely and away from each other, one end of the extension column 6411 is slidingly and telescopically retracted in the outer sleeve 641, and the installation space is in an open state, at this time, the auxiliary arm rope 5 can be arranged into the wheel groove of the rope pulley 43 from the open place, and the auxiliary arm hook does not need to pass through the installation space, so that the auxiliary arm rope 5 with the large-width auxiliary arm hook can be adapted.

[0055] When the auxiliary arm rope 5 slides in the wheel groove of the rope pulley 43, the limiting disc one 621 and the limiting disc two 622 are driven to rotate by friction, because the limiting disc one 621 and the limiting disc two 622 can be transversely separated, the rotating speeds of the limiting disc one 621 and the limiting disc two 622 are different, and then the limiting disc one 621 and the limiting disc two 622 are worn due to relative friction.

[0056] With reference to the drawings Figures 5 to 11To solve the problem, the following technical scheme is further provided: the center of the limiting disc one 621 is provided with a butt joint block 6211, the outer periphery of the butt joint block 6211 is fixedly provided with an extension block 6212, the center of the limiting disc two 622 is provided with a butt joint groove 6221, the outer periphery of the butt joint groove 6221 is in communication with an extension groove 6222, the butt joint block 6211 enters the inside of the butt joint groove 6221, and the extension block 6212 enters the inside of the extension groove 6222.

[0057] It should be noted that the connecting disc 642 is rotationally connected with the corresponding telescopic column 6411, and through the matching of the extension block 6212 and the extension groove 6222, the limiting disc one 621 and the limiting disc two 622 can be synchronously rotated.

[0058] Since the limiting disc one 621 and the limiting disc two 622 can be transversely separated, when the auxiliary arm sling rope 5 is moved out of the inside of the sling rope pulley 43 groove, the limiting disc one 621 and the limiting disc two 622 can be separated, so that the limiting wheel assembly 62 loses the limiting of the auxiliary arm sling rope 5.

[0059] Referring to the drawings in the specification Figures 9 to 11 To solve the problem, the following technical scheme is further provided: one side of the extension groove 6222 is provided with a limiting groove 6223, and the limiting disc one 621 is rotated to make the extension block 6212 enter the inside of the limiting groove 6223.

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

[0061] Further, the vehicle body 1 is provided with a winch mechanism 11, and the winch mechanism 11 is used for winding and releasing the auxiliary arm sling rope 5 and the main sling 22.

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

[0063] Still further, the vehicle body 1 is provided with a hydraulic mechanism 12, the hydraulic mechanism 12 comprises a hydraulic cylinder 14, the output end of the hydraulic cylinder 14 is rotationally connected with the main arm 2, and the vehicle body 1 is provided with an operation room 13.

[0064] It should be noted that the hydraulic mechanism 12 comprises a hydraulic oil tank, which provides hydraulic oil for the hydraulic cylinder 14, and the operation room 13 is an existing technology.

[0065] Still further, one end of the main arm 2 is provided with a connecting mechanism 21, the auxiliary arm 3 comprises a main frame 31, one end of the main frame 31 is provided with a connecting frame 33, and the connecting frame 33 is detachably connected with the connecting mechanism 21.

[0066] It needs to be explained that when the auxiliary hoist arm 3 needs to be used, the auxiliary hoist arm 3 is installed at one end of the main hoist arm 2, and then the connecting mechanism 21 and the connecting frame 33 are fixed by bolts.

[0067] Working principle:

[0068] The turnover seat one 61 drives the limiting wheel assembly 62 away from the sling pulley 43, and when the distance between the sling pulley 43 and the limiting wheel assembly 62 is increased to the maximum, the turnover is stopped, the installation space between the sling pulley 43 and the limiting wheel assembly 62 is the largest, and the auxiliary arm sling 5 and the auxiliary arm hook directly pass through the installation space.

[0069] The limiting wheel assembly 62 is lowered, the limiting wheel assembly 62 and the sling pulley 43 clamp the auxiliary arm sling 5, and the auxiliary arm sling 5 is pressed on the wheel groove of the sling pulley 43 by the gravity of the limiting wheel assembly 62 itself, so that the auxiliary arm sling 5 is prevented from being separated from the wheel groove of the sling pulley 43.

[0070] The limiting plate 63 is turned over in the direction close to the limiting wheel assembly 62, one end of the pin shaft one and the pin shaft two is respectively clamped into the inside of the corresponding clamping hole 631, and then the limiting is performed on the pin shaft one and the pin shaft two by tightening the nut.

[0071] When the limiting disc one 621 and the limiting disc two 622 move away from each other in the transverse direction, one end of the telescopic column 6411 slides and shrinks in the outer sleeve 641, and the installation space is in an open state, so that the auxiliary arm sling 5 can be arranged into the wheel groove of the sling pulley 43 from the open place.

[0072] Referring to the drawings in the specification Figure 12 , the application also provides a hoisting method of the iron tower installation hoisting equipment, which comprises the following steps:
