Description

Technical Field

[0001] The invention relates to the technical field of crane hoisting equipment, and in particular to a method for hoisting a tower winch through a balance beam. Background Art

[0002] In the process of hoisting large equipment, the winch, as one of its core components, plays a vital role. In order to protect the winch, the winch is generally placed inside the tower body. However, with the increase in frequency of use and changes in the working environment, the mechanical parts of the winch may suffer from wear and other problems, affecting its normal operation. At this time, the winch needs to be repaired or replaced. Some winches are installed inside the tower body. Since the winch has a small space inside the tower body, it is not convenient to repair it. However, since the winch is set inside the tower body and the winch is generally heavy, it is not convenient to move. The winch needs to be hoisted out of the tower body for inspection and replacement. The front side of the tower body has a front cavity hole, and the rear side of the tower body has a rear cavity hole. The winch needs to be lifted and moved out of the rear cavity hole by a forklift.

[0003] For example, a patent document with patent application number 202210072891.6 and publication date 2022.05.24 discloses a tower crane hoisting path guidance system for steel tower segments. The tower crane system includes a control room in which a controller is installed and connected to a central server; the steel tower includes an installed steel tower segment and a steel tower segment to be installed, and a camera is installed on a workbench on the installed steel tower segment; a camera is mounted at the center of the cross section corresponding to the steel tower segment to be installed and the installed steel tower segment respectively; A marker; a camera is connected to the central server; the central server calculates the distance between the installed steel tower and the uninstalled steel tower, and the distance between the two marking points; the central server transmits the identified contour and the calculated distance back to the controller, and the controller gives the corresponding tower crane path instructions. The above literature provides a path guidance method that can effectively give tower crane operation instructions during the steel tower docking process, avoid the problems of excessive personnel requirements and inconvenient communication in the traditional method, improve construction efficiency, and ensure construction safety.

[0004] In the above documents, heavy objects are hoisted by means of a tower crane, in which a triangular steel wire rope is used to keep the boom in a balanced state, and then the heavy object is raised or lowered by moving the steel wire rope on the boom. However, the boom can only swing in a horizontal plane and is not convenient for moving in a vertical direction. Moreover, the boom cannot better enter the front hole of the tower body due to the limitation of the triangular rope. In addition, the tower crane is complicated to install, which results in a low hoisting effect. Summary of the invention

[0005] The invention provides a method for hoisting a tower body winch through a balance beam, which can facilitate replacement of the winch in the tower body and has high operating efficiency.

[0006] To achieve the above object, the technical solution of the present invention is: a method for hoisting a tower winch through a balance beam, wherein the front and rear sides of the tower body are respectively provided with a front cavity hole and a rear cavity hole, a winch is provided inside the tower body, and the winch is moved out of the tower body by using a lifting device and a balance beam, wherein the lifting device includes a front hook, a rear hook, and a counterweight block, and the specific steps include: S1 presets the corresponding lifting position of the front hook and the counterweight on the balance beam, the weight of the balance beam, the length of the balance beam, and the weight of the winch. The weight of the counterweight is determined according to the position of the front hook on the balance beam, the length of the entire balance beam, and the weight of the balance beam. The position of the rear hook is determined according to the weight of the counterweight on the balance beam, the weight of the winch, and the length of the balance beam; the rear hook is located between the front hook and the connecting hole on the balance beam; S2 connects the counterweight block to the lower lifting ear on the front side of the balance beam, connects the front hook to the front hook position on the balance beam, and connects the rear hook to the rear hook position on the balance beam, so that the balance beam is in a balanced state; S3 The front hook and the rear hook are operated to raise the balance beam, so that the balance beam and the counterweight block leave the ground, and the front hook and the rear hook stop and no longer rise; S4 The front hook and the rear hook continue to move and extend the balance beam into the front cavity hole to the corresponding position above the winch; S5 connects the winch to the connecting hole on the balance beam, so that the balance beam is in a balanced state; The operation of the S6 front hook and the rear hook will raise the balance beam, so that the winch will be a certain distance away from the installation position of the tower body, and the front hook and the rear hook will stop and no longer rise; The front hook and rear hook of S7 move horizontally to move the winch to the corresponding position of the rear cavity hole, and the forklift extends from the rear cavity hole to the bottom of the winch; The front hook and rear hook of S8 are lowered, the winch is placed on a forklift, the winch is removed, the forklift moves to move the winch out of the tower, and the winch is placed on the ground.

[0007] The above setting determines the weight of the counterweight according to the weight of the balance beam, the position of the front hook on the balance beam and the total length of the balance beam, so that it can be in a balanced state when no heavy objects are hoisted, and then determines the position of the rear hook according to the weight of the counterweight, the length of the balance beam and the weight of the winch, so that it can be in a balanced state when the winch is hoisted. After determining the parameters, the front hook, the rear hook and the counterweight can be used to ensure that the balance beam remains horizontal when the winch is lifted or moved, reducing the risk of accidents caused by imbalance. In the process of moving the balance beam or hoisting the winch, the front hook keeps the tension on the balance beam unchanged, which is equivalent to providing a fulcrum for the balance beam. Before the winch is hoisted, The weight of the counterweight block relies on the pulling force of the rear hook to keep the balance beam in a horizontal position. When the balance beam is hoisted by the winch, the weight of the counterweight block relies on the weight of the winch to keep the balance beam in a horizontal position. At this time, the pulling force of the rear hook is reduced. Therefore, in the process of moving the balance beam or hoisting the winch, it is only necessary to adjust the pulling force of the rear hook on the balance beam accordingly. In this way, only the balance beam and two hooks are needed to keep the balance beam in a horizontal position before and after the winch is lifted, and the balance beam can be extended into the tower body to facilitate the lifting of the winch, and then the winch can be moved in the vertical direction by the two hooks, and then the winch can be moved out of the tower body by translating the two hooks to the corresponding forklift. The operation is convenient and reliable, and the operation effect is high.

[0008] Furthermore, after step S8, the method further includes: S9 places another winch on a forklift, and the forklift moves the other winch to the rear cavity hole, and connects the other winch to the connecting hole of the balance beam; S10 The front hook and the rear hook are operated to raise the balance beam, so that the other winch is away from the forklift for a distance, and the front hook and the rear hook stop and no longer rise; S11 The front hook and the rear hook continue to move to move the other winch to the installation position, remove the winch, and move the balance beam out of the front cavity hole and extend it out of the tower body.

[0009] With the above arrangement, the repaired or new winch can be removed from the rear cavity hole by a forklift, making it convenient to replace the winch.

[0010] Further, step S1 includes: presetting the distance between the front hook and the counterweight on the balance beam to be d1, the weight of the balance beam to be g1, and the total length of the balance beam to be L, according to formula (1): g1*d1=g2*(L-d1) (1), the weight of the counterweight is g2; step S1 includes: presetting the weight of the winch to be g3, the total length of the balance beam to be L, according to formula (2) g2*d2=g3*(L-d2), d2 is the distance between the rear hook and the connecting hole of the counterweight.

[0011] The above arrangement is based on the moment balance principle. When the winch is not hoisted, the balance beam is balanced by the counterweight. At this time, the front hook is used as a fulcrum to make the balance beam in a balanced state, so that it can be in a balanced state when the winch is not hoisted. The required weight of the counterweight can be conveniently determined by formula (1); when the winch is hoisted, the rear hook is used as a fulcrum to make the balance beam in a balanced state, and the position of the rear hook on the balance beam is calculated according to the calculated weight of the counterweight, so that the rear hook can make the balance beam in a balanced state when the balance beam and the winch are hoisted.

[0012] Furthermore, in step S3, when the front hook and the rear hook are in operation to raise the balance beam, the tension of the rear hook increases, so that the tension of the rear hook can bear the weight g2 of the counterweight block.

[0013] In the above arrangement, since the balance beam has not been connected to the winch in step S3, the weight of the counterweight can only be borne by the rear hook, and in step S2, the weight of the counterweight g2 is obtained. Therefore, only the pulling force of the rear hook is required to bear the weight of the counterweight, so that the balance beam can maintain a horizontal position.

[0014] Furthermore, in step S6, the front hook and the rear hook are operated to raise the balance beam, and the tension of the hook is reduced as the winch rises.

[0015] With the above arrangement, as the winch gradually rises, the weight of the winch is borne by the balance beam. Since a counterweight is provided on the other side of the balance beam, the tension of the rear hook is reduced, and the balance beam maintains a horizontal position under the action of the counterweight and the winch.

[0016] Furthermore, in step S8, the winch is placed behind the forklift, and the tension of the rear hook is increased so that the tension of the rear hook can bear the weight g2 of the counterweight.

[0017] With the above arrangement, as the winch is gradually placed on the forklift, the weight of the winch is shared by the forklift. At this time, the force exerted by the winch on the balance beam is reduced, the weight of the counterweight block remains unchanged, and the balance beam tilts. In order to avoid the tilting phenomenon, it is necessary to increase the tension of the rear hook so that the tension of the rear hook can bear the weight of the counterweight block, thereby keeping the balance beam in a horizontal position.

[0018] Furthermore, in step S10, when the front hook and the rear hook are in operation to raise the balance beam, the tension of the rear hook is reduced.

[0019] With the above arrangement, as the winch gradually rises, the weight of the counterweight is mainly borne by the balance beam. Since the counterweight is installed on the other side of the balance beam, the pulling force of the rear hook is reduced accordingly, so that the balance beam can maintain a horizontal position under the action of the counterweight and the winch.

[0020] Furthermore, in step S11, after the winch is placed in its installation position, the rear hook tension is increased so that the rear hook tension can bear the weight g2 of the counterweight.

[0021] With the above arrangement, as the winch is gradually placed at the tower installation position, the weight of the winch is shared at its installation position. At this time, the force exerted by the winch on the balance beam is reduced, the weight of the counterweight block remains unchanged, and the balance beam tilts. In order to avoid the tilting phenomenon, it is necessary to increase the tension of the rear hook so that the tension of the rear hook can bear the weight of the counterweight block, thereby keeping the balance beam in a horizontal position.

[0022] Furthermore, the balance beam is in a horizontal state during the process of moving or hoisting the winch.

[0023] With the above settings, the balance beam remains horizontal to ensure even load distribution and reduce the risk of tipping or sliding due to imbalance.

[0024] Furthermore, the front hook is connected to the balance beam, the rear hook is connected to the balance beam, and the counterweight is connected to the balance beam, all using steel wire ropes; the winch is connected to the balance beam using a sling.

[0025] With the above settings, the steel wire rope has high strength and good wear resistance, and can withstand greater tension, thereby ensuring the safety of the lifting operation; the surface of the sling is soft, which can effectively protect the surface of the hoisted object from wear.

[0030] S7 The front hook 6 and the rear hook 7 continue to move to move the winch 5 to the corresponding position of the rear cavity hole 2, and the forklift 8 extends from the rear cavity hole 2 to below the winch 5; S8 The front hook 6 and the rear hook 7 slowly drop down, the winch 5 is placed on the forklift 8, the winch 5 is unloaded, the forklift 8 moves to move the winch 5 out of the tower body, and the winch 5 is placed on the ground; S9: Place another winch 5 on the forklift 8, and the forklift 8 moves the other winch 5 to the rear cavity hole 2, and connects the other winch 5 to the connecting hole 33 of the balance beam 3; the other winch can be a new winch or a repaired winch.

[0031] S10 The front hook 6 and the rear hook 7 are operated to slowly raise the balance beam 3, so that the new winch 5 is away from the forklift 8 for a distance, and the front hook 6 and the rear hook 7 stop rising and are placed still for a period of time; S11 The front hook 6 and the rear hook 7 continue to move to move the other winch 5 to its installation position, remove the other winch 5, and move the balance beam 3 out of the front cavity hole 1 to extend out of the tower body. By using the front hook 6, the rear hook 7 and the counterweight 4, it can be ensured that the balance beam 3 remains horizontal when the winch 5 is lifted or moved, thereby reducing the risk of accidents caused by imbalance. In the process of moving the balance beam 3 or hoisting the winch 5, the front hook 6 keeps the tension on the balance beam 3 unchanged, which is equivalent to providing a fulcrum for the balance beam 3. Before the balance beam 3 is hoisted by the winch 5, the weight of the counterweight is kept constant. The balance beam 3 is kept in a horizontal position by the pulling force of the rear hook 7. When the balance beam 3 is hoisted by the winch 5, the weight of the counterweight block relies on the weight of the winch 5 to keep the balance beam 3 in a horizontal position. At this time, the pulling force of the rear hook 7 is reduced. Therefore, during the movement of the balance beam 3 or the hoisting of the winch 5, it is only necessary to adjust the pulling force of the rear hook 7 on the balance beam 3 accordingly to keep the balance beam 3 in a horizontal position, and the balance beam 3 will stop at a distance when moving to test the braking function of the front hook 6 and the rear hook 7 to prevent accidents caused by failure of the front hook 6 and the rear hook 7.

[0032] like Figure 2 As shown, in step S2, the distance between the front hook and the counterweight on the preset balance beam is d1, the weight of the balance beam is g1 and the total length of the balance beam is L. According to formula (1): g1*d1=g2*(L-d1) (1), the weight of the counterweight is g2; the weight of the winch is preset to be g3, the total length of the balance beam is L, according to formula (2) g2*d2=g3*(L-d2), d2 is the distance between the rear hook and the connection hole of the counterweight.

[0033] In step S3, as the front hook 6 and the rear hook 7 operate to slowly raise the balance beam 3, the tension of the rear hook 7 increases, so that the tension of the rear hook 7 can bear the weight g2 of the counterweight. Since in step S3, the balance beam 3 has not yet been connected to the winch 5, the weight of the counterweight 4 can only be borne by the rear hook 7, and in step S2, the weight g2 of the counterweight is obtained. Therefore, it is only necessary to increase the tension of the rear hook 7 to bear the weight of the counterweight, so that the balance beam 3 can maintain a horizontal position.

[0034] In step S6, the front hook 6 and the rear hook 7 operate to slowly raise the balance beam 3. As the winch 5 gradually rises, the tension of the rear hook 7 gradually decreases. As the winch 5 gradually rises, the weight of the winch 5 is borne by the balance beam 3. Since a counterweight 4 is provided on the other side of the balance beam 3, the tension of the rear hook 7 is reduced, and the movement of the balance beam is achieved through the front hook 6. The balance beam 3 maintains a horizontal position under the action of the counterweight 4 and the winch 5.

[0035] In step S8, after the winch 5 is placed on the forklift 8, the tension of the rear hook 7 is increased, so that the tension of the rear hook 7 can bear the weight g2 of the counterweight. In this embodiment, the connecting hole connected to the winch 5 is a rotatable connecting hole, which is rotatable through a rotating shaft (not shown in the figure). Before the winch 5 is placed on the forklift 8, the winch 5 is rotated by a certain angle, so that the winch 5 can be better placed on the forklift 8. As the winch 5 is gradually placed on the forklift 8, the weight of the winch 5 is shared by the forklift 8. At this time, the force of the winch 5 on the balance beam 3 is reduced, the weight of the counterweight remains unchanged, and the balance beam 3 tilts. In order to avoid the tilting phenomenon, the tension of the rear hook 7 needs to be increased so that the tension of the rear hook 7 can bear the weight of the counterweight, thereby making the balance beam 3 in a horizontal position.

[0036] In step S10, the front hook 6 and the rear hook 7 operate to slowly raise the balance beam 3, and the tension of the rear hook 7 decreases. During the gradual rise of the winch 5, the weight of the counterweight is mainly borne by the balance beam 3. Since the counterweight 4 is installed on the other side of the balance beam 3, the tension of the rear hook 7 is reduced accordingly, so that the balance beam 3 can maintain a horizontal position under the action of the counterweight 4 and the winch 5, for example, gradually decreases to close to 0.

[0037] In step S11, after the winch 5 is placed at its installation position, the tension of the rear hook 7 increases, so that the tension of the rear hook 7 can bear the weight g2 of the counterweight 4. As the winch 5 is gradually placed at the tower installation position, the weight of the winch 5 is shared at its installation position. At this time, the force of the winch 5 on the balance beam 3 is reduced, the weight of the counterweight remains unchanged, and the balance beam 3 tilts. In order to avoid the tilting phenomenon, it is necessary to increase the tension of the rear hook 7 so that the tension of the rear hook 7 can bear the weight of the counterweight, thereby making the balance beam 3 in a horizontal position.

[0038] The balance beam 3 is in a horizontal state during the process of moving or hoisting the winch 5. Maintaining the horizontal state of the balance beam 3 can ensure uniform load distribution and reduce the risk of overturning or sliding due to imbalance.

[0039] The front hook 6 is connected to the balance beam 3, the rear hook 7 is connected to the balance beam 3, and the counterweight 4 is connected to the balance beam 3. All of them are connected by steel wire ropes. The steel wire ropes have high strength and good wear resistance and can withstand large tension, thereby ensuring the safety of the lifting operation.

[0040] The winch 5 is connected to the balance beam 3 by a sling, and the surface of the sling is soft, which can effectively protect the surface of the suspended object from wear.

[0041] The working principle of the present invention is as follows: a winch 5 is installed inside the tower body, and a front cavity hole 1 and a rear cavity hole 2 are opened at the corresponding positions of the tower body, so that the balance beam 3 can reach the corresponding position of the winch 5. The balance beam 3 is provided with a front upper lug 31 and a rear upper lug 32, the front hook 6 is connected to the front upper lug 31, the rear hook 7 is connected to the rear upper lug 32, and after confirming the parameters of the balance beam 3 and the winch 5, the weight of the counterweight is calculated, and the counterweight 4 is connected to the lower lug 34 of the balance beam 3. Since the connection hole 33 of the balance beam 3 is not connected to the winch 5, during the operation of the front hook 6 and the rear hook 7, the rear hook 7 needs to gradually increase the pulling force so that the pulling force of the rear hook 7 can be The balance beam 3 is kept horizontally by carrying the weight of the counterweight block, and the tension of the front hook 6 remains unchanged, which is equivalent to providing a fulcrum for the horizontal beam. After the balance beam 3 and the counterweight block 4 leave the ground for a certain distance, the front hook 6 and the rear hook 7 stop running, so that the balance beam 3 and the counterweight block 4 are suspended in the air to test the braking conditions of the front hook 6 and the rear hook 7 to prevent the balance beam 3 from falling due to the brake failure of the front hook 6 and the rear hook 7. Then, the balance beam 3 is moved to the top of the winch 5 through the front cavity hole 1. The winch 5 is connected to the balance beam 3. In the process of the balance beam 3 lifting the winch 5, the rear hook 7 gradually reduces the tension so that the balance beam 3 can maintain a horizontal position by relying on the weight of the counterweight block and the weight of the winch 5; After the balance beam 3 is lifted, it continues to remain stationary for a period of time to test the braking conditions of the front hook 6 and the rear hook 7, and then the balance beam 3 is moved to the corresponding position of the rear cavity hole 2, and the forklift 8 is inserted into the rear cavity hole 2 to be under the winch 5. The balance beam 3 slowly falls. When the winch 5 contacts the forklift 8, the rear hook 7 gradually increases the pulling force, so that the pulling force of the rear hook 7 can bear the weight of the counterweight block and keep the balance beam 3 in a horizontal position. At this time, the winch 5 is unloaded on the forklift 8, and the forklift 8 unloads the winch 5 on the ground. The forklift 8 passes the new winch 5 through Move to the bottom of the connecting hole 33 of the balance beam 3 through the rear cavity 2, connect the balance beam 3 with the winch 5, and the front hook 6 and the rear hook 7 pull up the balance beam 3. During the pulling process, the pulling force of the rear hook 7 gradually decreases, so that the balance beam 3 remains horizontal under the action of the counterweight 4 and the winch 5. The front hook 6 and the rear hook 7 stop running, so that the balance beam 3 and the counterweight 4 are suspended in the air. After a period of time, the balance beam 3 moves the winch 5 to its installation position, and then the winch 5 is removed, and the balance beam 3 is moved out of the tower body through the front cavity 1.
