Description

A working platform with a manipulator

technical field

The invention relates to tunnel construction equipment, in particular to a working platform with a manipulator.

Background technique

In order to control the appropriate release of surrounding rock stress and deformation of surrounding rock, increase the structural safety of the tunnel and facilitate construction, the initial support is implemented immediately after the excavation of the soft surrounding rock tunnel. part. Different primary support methods are determined according to different surrounding rock grades. For the surrounding rock of grade IV and above, steel arch support is generally used in the support process. At present, the installation of steel arch frames in tunnel construction in my country is mostly done by pure manpower. Not only is the labor cost high, the completion time is long, and the work efficiency is low, but also due to the high labor intensity and poor construction environment, the construction personnel are often injured and bleeding during the arching process. Therefore, mechanized construction instead of pure manual construction will be an inevitable trend.

The existing arch installation trolley is provided with an operation platform, and there is a slewing device at the bottom of the operation platform. The operation platform can be rotated within a certain range through the slewing device, and a manipulator is also provided at the front end of the operation platform, and the steel is clamped by the manipulator. The arch frame, and then the three-section telescopic arm lifts the operating table and the manipulator to the predetermined position near the installation arch frame, and then adjusts the angle in the horizontal direction and the pitching action of the manipulator through the rotary device to complete the alignment and alignment, and finally the operator on the operating platform Construction workers complete the connection between the arches. The manipulator on the workbench can only be adjusted in the height direction, and the entire workbench is controlled by the control mechanism in the operating room to control its rotation angle, and the operating room is far away from the working platform, so it is difficult to accurately observe the installation of the arch , the operator can only be guided to adjust the state of the work platform by issuing instructions from the construction personnel on the work platform. Too late to reflect.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the present embodiment provides a kind of working platform with manipulator, comprises working platform 6, and one end of described working platform 6 is hinged with trolley arm 9, and the other end is connected with trolley arm The telescopic ends of the pitching and telescopic parts 7 are hinged, and a manipulator is provided on the outside of the working platform 6. The lower end of the manipulator is hinged with the working platform. The telescopic end is connected with the manipulator to realize the swing of the manipulator relative to the working platform.

In this embodiment, the pitch telescopic member 7 is a pitch telescopic oil cylinder, and the swing telescopic member 5 is a swing telescopic oil cylinder, and a manipulator operation panel is provided on the working platform to realize precise control of the manipulator.

As shown in Figure 1, the manipulator includes a telescopic boom 3 and a telescopic boom 2 connected to the telescopic boom. A telescopic oil cylinder (omitted among the figures) is arranged, wherein the telescopic boom and the telescopic forearm are at least two-stage telescopic. A clamping mechanism 1 is installed on the telescopic arm, wherein the telescopic arm 3 is connected with the swing telescopic member 5 to realize the swing of the telescopic arm 3 relative to the two sides of the working platform 6 . The telescopic arm 2 realizes the inverting of the telescopic arm 2 relative to the telescopic boom 3 by pulling the turning oil cylinder 4 .

As shown in Figure 2, it includes a clamp 18 arranged symmetrically on the left and right and installed on the bracket. The clamp 18 includes two handle side plates 11, and two symmetrical The handle 10 provided, one end of the handle 10 is hinged with the handle side plate 11, the lower ends of the two handles 10 are hinged through the hinge shaft 15, and the lower end of the hinge shaft 15 is provided with a locking device 14. The telescoping rod end that locking device 14 is arranged is connected with hinge shaft. The opening and closing of the two grippers is realized through the telescopic movement of the locking device 14 .

In this embodiment, the gripper 10 is a bent gripper, the bent part of the gripper is hinged to the gripper side plate 11 through a pin shaft 13, and the bent extensions at the lower ends of the two grippers are connected through a hinge shaft 15 , so that the handle 10 can rotate around the pin shaft 13 at a certain angle.
