[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the mobile lifting and hoisting equipment of the practical design includes a movable body 1, on which a rotatable turntable 2 is mounted, and on which a fixed arm 3 is arranged; on the fixed arm 3, a deflectable deflection arm 4 is movably mounted, and a first hydraulic cylinder 3.1 connected to the deflection arm 4; the outer end of the deflection arm 4 is hinged with a hanger 5, and on the hanger 5, a construction hanging basket 6 is mounted.

[0023] In this embodiment, the equipment is first moved to the work site where lifting operations are required through the movable body 1. The rotatable turntable 2 located on the body 1 allows the entire lifting system to rotate 360 ​​degrees on the horizontal plane; the first hydraulic cylinder 3.1 is connected between the deflection arm 4 and the fixed arm 3, and is used to control the deflection angle of the deflection arm 4. The fixed arm 3 is installed on the turntable 2, and is adjusted on the vertical plane through the movably installed deflection arm 4 thereon.

[0024] As a supplement, the vehicle body 1 can be moved by towing, relying on external traction equipment (such as a tractor) to pull the entire lifting equipment. The vehicle body 1 can also be moved by self-driving walking, and the movement is achieved by its own power system (such as an engine, a motor, etc.). The moving method is a prior art and will not be described in detail here.

[0025] The construction hanging basket 6 is used to carry workers or goods. Through the connection between the hanger 5 and the deflection arm 4, it can be raised and lowered and moved with the deflection and extension of the deflection arm 4, thereby realizing the lifting and transportation of workers or goods.

[0026] In addition, the rotatable turntable 2 can be a universal rotating platform driven by a power source such as an electric motor, a hydraulic motor or a pneumatic motor. These power sources transmit power to the rotating platform through mechanisms such as reducers, drive shafts and gears, so that it can rotate smoothly and accurately. This is an existing driving method in the field and will not be elaborated on here.

[0027] As an embodiment, the deflection arm 4 includes a front arm 4.1 and a rear arm 4.2. An adjustment channel with a reserved opening is provided inside the rear arm 4.2 along the length direction, and the rear arm 4.2 can be extended and retracted along the opening toward the adjustment channel. A second hydraulic cylinder 4.3 connected to the front arm 4.1 is installed on the rear arm 4.2.

[0028] The second hydraulic cylinder 4.3 is connected between the front arm 4.1 and the rear arm 4.2, and drives the rear arm 4.2 to move in the adjustment channel through the telescopic movement of the hydraulic cylinder, thereby realizing the adjustment of the length of the deflection arm 4.

[0029] As an implementation mode, the construction hanging basket 6 comprises a bottom plate 6.1, and the upper plate surface of the bottom plate 6.1 is surrounded by a guardrail 6.2 with an entrance and exit reserved on one side.

[0030] The bottom plate 6.1 is the basic part of the construction hanging basket, which provides a solid working platform on which workers can stand to perform operations; the guardrail 6.2 surrounds the upper plate surface of the bottom plate 6.1 to protect the workers and prevent them from accidentally falling.

[0031] Specifically, the guardrail 6.2 is a steel frame beam structure formed by a plurality of transverse beams, longitudinal beams and vertical beams cross-connected, and this structure ensures the strength of the guardrail.

[0032] Specifically, a sliding door frame 6.3 is provided at the entrance and exit of the guardrail 6.2, and a guide rail 6.4 that slides with the sliding door frame 6.3 is provided on the adjacent guardrail 6.2. The design of the sliding door frame 6.3 allows the door panel to be opened or closed when necessary to control the passage in and out of the construction hanging basket.

[0033] In addition, a pin hole 6.5 is reserved on the sliding door frame 6.3, and a latch 6.6 for locking the pin hole 6.5 is also provided on the guardrail 6.2. When the sliding door frame 6.3 is in a closed state, the staff can fix the door frame by inserting the latch 6.6 into the pin hole 6.5 to prevent it from opening accidentally.

[0034] As an embodiment, the vehicle body 1 is also provided with an adjusting screw 7 which can be axially moved in the vertical direction. A supporting seat 7.1 is provided at the bottom end of the adjusting screw 7. The adjusting screw 7 can be axially moved in the vertical direction and can be driven by rotating the handle of the screw or by using other power devices (such as electric or hydraulic devices). The supporting seat 7.1 is fixed to the bottom end of the adjusting screw 7 for contacting the ground and providing support.

[0035] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.
