Description

Technical Field

[0001] This utility model relates to the field of general-purpose downhole machinery, and in particular to a novel lifting boom unit. Background Technology

[0002] U-shaped steel canopies, as a type of canopy support, are widely used in the support of medium-deep roadways in coal mines. However, currently, most of the installation work of these canopies still relies on manual labor. Specifically, although there are some lifting devices available, they cannot be used underground due to the special structure of the U-shaped steel canopy; that is, current lifting devices are mostly lifting platforms or single lifting arms, which cannot fully lock the U-shaped steel canopy in place, nor can they be flexibly adjusted in angle and positioned. When working manually, underground workers need to first raise the U-shaped steel canopy to the installation position and then fix it in place with clamps. Because the top beam of the U-shaped steel canopy is high and heavy, the labor intensity for workers during construction is enormous, the construction safety risks are significant, and the construction efficiency is low. In short, these issues result in lengthy implementation times and high risks, not only affecting normal underground production and reducing production efficiency, but also threatening the life, health, and safety of underground workers.

[0003] There is currently no corresponding solution to the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of lifting arm unit that can replace manual labor to lift steel sheds and improve operational safety.

[0005] The lifting arm unit includes a lifting arm mechanism and a support arm mechanism; The lifting arm mechanism and the support arm mechanism are rotatably mounted on the downhole self-propelled equipment via a horizontal slewing mechanism; That is, the lifting arm mechanism and the support arm mechanism can rotate horizontally on the self-propelled equipment; The lifting arm mechanism includes a lifting arm body hinged to a slewing mechanism, and a lifting cylinder is also hinged between the lifting arm body and the slewing mechanism. That is, the lifting arm body can be lifted by the action of the lifting cylinder; The lifting arm body is provided with a vertical rotation mechanism at the front; a mechanical gripper is hinged to the rotor of the vertical rotation mechanism; and an angle adjustment cylinder is provided between the mechanical gripper and the rotor of the vertical rotation mechanism. That is, the mechanical gripper can be rotated by the vertical rotation mechanism to change its orientation angle, that is, the orientation angle of the mechanical gripper in the left and right direction; the angle adjustment cylinder can control the orientation angle of the mechanical gripper in the front and back direction. In other words, the rotation of the horizontal slewing mechanism, in conjunction with the lifting cylinder, lifts the lifting arm body, thereby controlling the basic position of the mechanical gripper within the tunnel. After the basic position of the mechanical gripper is determined, its vertical rotation mechanism can control the orientation angle of the mechanical gripper in the left and right directions, and the angle adjustment cylinder can control the orientation angle of the mechanical gripper in the front and back directions. This enables the mechanical gripper to achieve a wide range of multi-angle displacement control within the tunnel, meeting the lifting and assembly requirements and precision of the U-shaped steel shed.

The planar rotary mechanism is equipped with a support unit, and the support unit is powered by a locking cylinder.

[0007] In other words, based on the lifting arm mechanism, i.e. the mechanical gripper, one side of the shed is fixed and lifted, while the other side of the shed can be supported and positioned by the support arm mechanism, thereby achieving stable lifting of the equipment and limiting the equipment during lifting to prevent the equipment from rotating and injuring people.

It can reduce manpower consumption, improve construction efficiency, and especially improve construction safety. Attached Figure Description

Detailed Implementation

[0010] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a novel lifting arm unit, comprising a lifting arm mechanism and a support arm mechanism. The lifting arm mechanism and the support arm mechanism are rotatably mounted on the downhole self-propelled equipment 1 via the horizontal slewing mechanism 2; That is, the lifting arm mechanism and the supporting arm mechanism can rotate horizontally on the self-propelled device 1 based on the horizontal rotation mechanism 2; The lifting arm mechanism includes a lifting arm body 6 hinged to a rotary mechanism, and a lifting cylinder 5 is also hinged between the lifting arm body 6 and the rotary mechanism. That is, by the action of the lifting cylinder 5, the lifting arm body 6 can be lifted; The lifting arm body 6 is provided with a vertical rotation mechanism 10 at the front; a mechanical gripper 7 is hinged on the rotor of the vertical rotation mechanism 10; and an angle adjustment cylinder 9 is provided between the mechanical gripper 7 and the rotor of the vertical rotation mechanism 10. That is, the mechanical gripper 7 can be rotated by the vertical rotation mechanism 10 to change its orientation angle, that is, the orientation angle of the mechanical gripper 7 in the left and right directions; the angle adjustment cylinder 9 can control the orientation angle of the mechanical gripper 7 in the front and back directions. In other words, the rotation of the horizontal slewing mechanism 2, in conjunction with the lifting cylinder 5, lifts the lifting arm body 6, thereby controlling the basic position of the mechanical gripper 7 within the tunnel. After the basic position of the mechanical gripper 7 is positioned, its vertical rotation mechanism 10 can control the orientation angle of the mechanical gripper 7 in the left and right directions, and the angle adjustment cylinder 9 can control the orientation angle of the mechanical gripper 7 in the front and back directions. This enables the mechanical gripper 7 to achieve a wide range of multi-angle displacement control within the roadway, meeting the lifting and assembly requirements and precision of the U-shaped steel shed.

[0011] The support arm mechanism includes a support arm body 8 hinged to a rotary mechanism, and a lifting cylinder 5 is also hinged between the support arm body 8 and the rotary mechanism. That is, by the action of the lifting cylinder 5, the lifting of the support arm body 8 can be controlled; The lifting arm body 6 is provided with a vertical rotation mechanism 10 at the front; an assembly base is fixedly provided on the rotor of the vertical rotation mechanism 10, and a planar rotation mechanism 11 is also provided on the assembly base. The planar rotary mechanism 11 is equipped with a support unit, and the support unit is powered by a locking cylinder.

[0012] In other words, based on the lifting arm mechanism, namely the mechanical gripper 7, one side of the canopy is fixed and lifted, while the other side of the canopy can be supported and positioned by the support arm mechanism, thereby achieving stable lifting of the equipment and limiting the equipment during lifting to prevent the equipment from rotating and injuring people.

[0013] In Example 1, the self-propelled device 1 is a hydraulically powered tracked self-propelled device 1, and a power unit 4 is integrated on the self-propelled device 1.

[0014] That is, the power unit 4 is connected to the aforementioned power mechanisms and drives the aforementioned devices to operate independently or in concert.

[0015] In Example 2, the rotary mechanism includes a rotary support, on which a rotating sleeve is rotatably mounted; the rotating sleeve is provided with an assembly panel. That is, the rotating sleeve is powered by a power unit 4.

[0016] Preferably, the lifting arm body 6, the support arm body 8, and the lifting cylinder 5 are respectively hinged on their respective mounting panels.

[0017] The result is a smooth and seamless device operation.

[0018] In Example 3, a secondary telescopic arm 61 is sleeved inside the lifting arm body 6; the secondary telescopic arm 61 is driven and controlled to extend and retract by a secondary telescopic hydraulic cylinder fixedly installed at its tail end inside the lifting arm.

[0019] This results in a longer lifting stroke for the lifting arm.

[0020] In Example 4, the mechanical gripper 7 includes a gripper base, on which multiple grippers are movably arranged, and the multiple grippers are divided into at least two groups facing each other; each group of grippers is powered and connected to a clamping hydraulic cylinder; that is, driving the gripper base can drive the grippers to move in opposite directions to lock. The gripper base is also provided with a clamping hydraulic cylinder, and the piston of the clamping hydraulic cylinder is positioned between the opposing grippers.

[0021] That is, after the gripper locks, the hydraulic cylinder pushes forward to further secure the object being locked.

[0022] In Example 5, the facade rotation mechanism 10 is hinged to the front end face of the support arm body 8, and an adjusting cylinder 9 is also provided between the facade rotation mechanism 10 and the support arm body 8.

[0023] This achieves the effect of fine-tuning the pitch angle of the support unit at the front.

[0024] Example 6, refer to the accompanying drawings in the specification. Figure 1 The support unit is a constraint frame 81 with hinges on both sides, and the locking cylinder is located between the two constraint frames 81.

[0025] This achieves the effect of fully locking the steel shed.

[0026] Example 7, refer to the accompanying drawings in the specification. Figure 2 The support unit is a set of constraint wheels 82 arranged opposite to each other, that is, the gap between the two constraint wheels 82 is used for the nesting and limiting of the steel shed side frame; The locking cylinder is mounted on the wheel frame of the two constraint wheels 82, and the wheel frame is movably mounted on the outer shell of the support unit.

[0027] That is, by pushing the locking cylinder, the wheel frame, i.e. the constraint wheel 82, moves towards the mechanical gripper 7, so as to achieve a more convenient locking of the steel shed.

[0028] Preferably, the self-propelled device 1 is further provided with an electrical control unit 3, which integrates a control unit. The control unit is connected to each action unit through a solenoid valve signal, thereby realizing semi-automatic operation. The control unit is also connected to a remote controller, thereby realizing remote control.
