[0056] A use method of a multifunctional construction hoist for a construction site, comprising:

[0057] The winch device 205 is controlled to run, and the winch device 205 does a winding or releasing behavior on the two traction steel wires 203 when working, the hanging basket 201 will be lifted when the two traction steel wires 203 are wound, and the hanging basket 201 will be lowered when the two traction steel wires 203 are released, and the two groups of guide wheels 204 will roll on the inner guide rail surface of the guide rail frame 1 in the process of lifting or lowering the hanging basket 201;

[0058] Due to the uneven distribution of goods and construction personnel in the hanging basket 201, the stress of each part of the hanging basket 201 is uneven, and then the hanging basket 201 will be slightly inclined relative to the guide rail frame 1, and the guide rail frame 1 will drive the inner lining pad 3 to move synchronously when the guide rail frame 1 is inclined, and the counterweight block 503 will have a tendency to move vertically downward under the action of its own gravity when the inner lining pad 3 is inclined, and the counterweight block 503 is connected with the counterweight swing shaft 502, and the counterweight swing shaft 502 can rotate in the inner side of the upper adapter frame 501;

[0059] When the inner lining plate 3 is in the inclined state, the counterweight 503 and the counterweight swing shaft 502 are always in the vertical state, the angle between the inner lining plate 3 and the counterweight swing shaft 502 changes, the angle between the inclined side of the inner lining plate 3 and the counterweight swing shaft 502 decreases, in the process, the counterweight swing shaft 502 exerts a side thrust on the driving shaft 505, under the action of the side thrust, one end of the driving shaft 505 rotates around the connection between the counterweight swing shaft 502 and the upper adapter frame 501, at the same time, the end of the driving shaft 505 also rotates inside the lower adapter frame 504, the other end of the driving shaft 505 exerts a side thrust on the lever shaft 601, under the action of the thrust, the lever shaft 601 rotates inside the adapter rear seat 603 through the adapter shaft 602;

[0060] At the same time, the lever core makes an extension movement in the other end of the lever shaft 601, and pushes the hydraulic drive shaft 702 to extrude into the hydraulic drive cylinder 701, as the internal hydraulic pressure of the hydraulic drive cylinder 701 gradually rises, the hydraulic oil in the hydraulic drive cylinder 701 enters the hydraulic tank on the side that is raised upward through the hydraulic oil pipe, as the pressure in the hydraulic tank rises, the hydraulic shaft 401 in the hydraulic tank makes an extension movement, the hydraulic shaft 401 exerts a thrust on the lever frame 402, under the action of the thrust, the two guide wheels 204 on the lever frame 402 move towards the direction of the guide rail frame 1, so as to correct the hanging basket 201.

[0061] Working principle, in use:

[0062] The winch device 205 is controlled to operate, the winch device 205 performs winding or releasing behavior on the two traction steel wires 203 when working, the hanging basket 201 will be lifted when the two traction steel wires 203 are wound, the hanging basket 201 will be lowered when the two traction steel wires 203 are released, the two groups of guide wheels 204 will roll on the inner guide rail surface of the guide rail frame 1 in the process of lifting or lowering the hanging basket 201;

[0063] Due to the uneven distribution of goods and construction personnel in the hanging basket 201, the stress of each part of the hanging basket 201 is uneven, which in turn causes the hanging basket 201 to tilt relative to the guide rail frame 1. When the guide rail frame 1 tilts, the inner lining pad 3 moves synchronously. When the inner lining pad 3 tilts, the counterweight block 503 has a tendency to move vertically downward under the action of its own gravity. Since the counterweight block 503 is connected to the counterweight swing shaft 502, and the counterweight swing shaft 502 can rotate inside the upper layer adapter frame 501, the counterweight block 503 and the counterweight swing shaft 502 are always in a vertical state when the inner lining pad 3 is in a tilted state. The angle between the inner lining pad 3 and the counterweight swing shaft 502 changes, and the angle between the tilted side of the inner lining pad 3 and the counterweight swing shaft 502 decreases. In this process, the counterweight swing shaft 502 exerts a side thrust on the drive shaft 505. Under the action of the side thrust, one end of the drive shaft 505 rotates around the connection between the counterweight swing shaft 502 and the upper layer adapter frame 501, and the end of the drive shaft 505 also rotates inside the lower layer adapter frame 504. The other end of the drive shaft 505 exerts a side thrust on the lever shaft 601. The lever shaft 601 rotates inside the adapter rear seat 603 through the adapter shaft 602 under the action of the thrust. At the same time, the lever core inside the other end port of the lever shaft 601 extends and pushes the hydraulic drive shaft 702 to extrude into the hydraulic drive cylinder 701. As the internal hydraulic pressure of the hydraulic drive cylinder 701 gradually rises, the hydraulic oil in the hydraulic drive cylinder 701 enters the hydraulic tank on the side that is tilted upward. As the pressure in the hydraulic tank rises, the hydraulic shaft 401 in the hydraulic tank extends. The hydraulic shaft 401 exerts a thrust on the lever frame 402. Under the action of the thrust, the two guide wheels 204 on the lever frame 402 move towards the guide rail frame 1, thereby correcting the hanging basket 201. The corrected hanging basket 201 is balanced with the two guide rail surfaces inside the guide rail frame 1, improving the balance of the hanging basket 201 and preventing the hanging basket 201 from producing abnormal friction on the guide rail surfaces inside the guide rail frame 1, thereby improving the stability of the elevator during use.

[0064] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical scope disclosed by the present application and according to the technical solutions and inventive concepts of the present application, which should be covered within the protection scope of the present application.

A multi-functional construction hoist for construction sites according to claim 3, characterized in that, A drive shaft (505) is rotatably connected to the other end of the lever shaft (601), and a lower adapter (504) is rotatably connected to the other end of the drive shaft (505). The lower adapter (504) is connected to the counterweight pendulum shaft (502).

5. A method of using a construction site multi-functional construction elevator according to any one of claims 1-4, characterized in that, include: Control the operation of the winch (205). When the winch (205) is working, it will rewind or release the two traction cables (203). When the two traction cables (203) are rewound, the basket (201) will be lifted. When the two traction cables (203) are released, the basket (201) will be lowered. During the process of lifting or lowering the basket (201), the two sets of guide wheels (204) will roll on the inner guide rail surface of the guide rail frame (1). Because the distribution of goods and construction personnel in the hanging basket (201) is uneven, the force on various parts of the hanging basket (201) will be uneven, which will cause the hanging basket (201) to tilt slightly relative to the guide rail frame (1). When the guide rail frame (1) tilts, it will drive the inner lining plate (3) to move synchronously. When the inner lining plate (3) tilts, the counterweight (503) will tend to move vertically downward under its own weight. Since the counterweight (503) is connected to the counterweight swing shaft (502), and the counterweight swing shaft (502) can rotate inside the upper transfer frame (501); When the inner liner (3) is tilted, the counterweight (503) and the counterweight swing shaft (502) are always in a vertical state. The angle between the inner liner (3) and the counterweight swing shaft (502) changes. The angle between the tilted side of the inner liner (3) and the counterweight swing shaft (502) decreases. During this process, the counterweight swing shaft (502) applies a lateral thrust to the drive shaft (505). Under the action of the lateral thrust, one end of the drive shaft (505) rotates around the connection between the counterweight swing shaft (502) and the upper adapter frame (501). At the same time, the end of the drive shaft (505) also rotates inside the lower adapter frame (504). The other end of the drive shaft (505) applies the lateral thrust to the lever shaft (601). Under the action of the thrust, the lever shaft (601) rotates inside the adapter seat (603) through the adapter shaft (602). Meanwhile, the inner core of the lever makes extension movement in the other port of the lever shaft (601) and pushes the hydraulic drive shaft (702) to extrude into the hydraulic drive cylinder (701), as the internal hydraulic pressure of the hydraulic drive cylinder (701) gradually increases, the hydraulic oil in the hydraulic drive cylinder (701) enters the hydraulic tank on the side of the upward tilt through the hydraulic oil pipe, as the pressure in the hydraulic tank increases, the hydraulic shaft (401) in the hydraulic tank makes extension movement, the hydraulic shaft (401) exerts a pushing force on the lever frame (402), under the action of the pushing force, the two guide wheels (204) on the lever frame (402) move towards the direction of the guide rail frame (1), so as to be able to play a correcting role on the hanging basket (201).
