Description

Technical Field

[0001] The utility model relates to the technical field of tunnel arch erecting machines, in particular to a foldable operating platform of a tunnel arch erecting machine. Background Art

[0002] The tunnel arch machine is used to transfer the steel arch frame segments to the predetermined installation position inside the tunnel, and then manually assemble and weld the steel arch frames of each segment into a complete steel arch frame. The operator stands on the operating platform of the arch machine in the tunnel to perform assembly, welding and other work, so it is often necessary to adjust the height of the operating platform according to the height of the working surface. Since the existing operating platform is large in size and has a fixed structure, even if some operating platforms have the function of adjusting the height, they are still large in size. At the same time, after the assembly, welding and other work are completed, the operating platform occupies a large space in the tunnel, making it inconvenient to move the arch machine in the tunnel. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a foldable and flat operating platform for a tunnel arch erecting machine. At the same time, the height of the operating platform can be arbitrarily adjusted within a certain stroke, which is convenient for operators to use while greatly reducing the volume of the operating platform and improving the flexibility of the arch erecting machine to move in the tunnel.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A foldable operating platform for a tunnel arch machine is connected to the top of a frame of the tunnel arch machine. The foldable operating platform includes a standing platform, a transition connection frame, a first telescopic drive and a second telescopic drive. Two sides of one end of the transition connection frame are respectively hinged to two sides of the top of the frame through pins, and two sides of the other end of the transition connection frame are respectively hinged to two sides of one end of the standing platform through pins; one end of the first telescopic drive is hinged to the top of the frame through a pin, and the other end of the first telescopic drive is hinged to the transition connection frame through a pin; one end of the second telescopic drive is hinged to the transition connection frame through a pin, and the other end of the second telescopic drive is hinged to the standing platform through a pin; through the cooperation of the first telescopic drive and the second telescopic drive, the standing platform can be switched to be raised and folded and laid flat on the top of the frame.

[0006] The standing platform comprises a frame and a steel plate, and the steel plate is laid flat and fixed on the top of the frame.

[0007] The skeleton and the transition connection frame are both formed by welding rectangular steel pipes.

[0008] The first telescopic actuator and the second telescopic actuator are hydraulic cylinders or pneumatic cylinders.

[0009] The utility model adopts the above technical scheme. Through the mutual cooperation of the first telescopic drive and the second telescopic drive, the standing platform can be raised to a horizontal state for the operating workers to work, and the standing platform can also be retracted and laid flat on the top of the frame of the tunnel arch machine, thereby realizing the foldable design of the operating platform and greatly improving the flexibility of the tunnel arch machine in the tunnel; in addition, through the mutual cooperation of the first telescopic drive and the second telescopic drive, the height of the operating platform can be arbitrarily adjusted within a certain stroke, which is convenient for the operating workers to use while greatly reducing the volume of the operating platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0011] Figure 1 This is a schematic diagram of the utility model when the standing platform is extended;

[0012] Figure 2 It is a schematic diagram of the utility model when the standing platform is retracted. DETAILED DESCRIPTION

[0013] like Figure 1-2 As shown, the utility model provides a foldable operating platform for a tunnel arch machine, and the foldable operating platform is connected to the top of a frame 1 of the tunnel arch machine.

[0014] The foldable operating platform includes a standing platform 2, a transition connection frame 3, a first telescopic drive 4 and a second telescopic drive 5. The standing platform 2 includes a frame and a steel plate, which is laid flat and fixed on the top of the frame. The surface of the steel plate has a texture to prevent slipping. The frame and the transition connection frame 3 are both welded by rectangular steel pipes.

[0015] The two sides of one end of the transition connection frame 3 are hinged to the two sides of the top of the frame 1 through pins, and the two sides of the other end of the transition connection frame 3 are hinged to the two sides of one end of the standing platform 2 through pins; one end of the first telescopic drive 4 is hinged to the top of the frame 1 through a pin, and the other end of the first telescopic drive 4 is hinged to the transition connection frame 3 through a pin; one end of the second telescopic drive 5 is hinged to the transition connection frame 3 through a pin, and the other end of the second telescopic drive 5 is hinged to the standing platform 2 through a pin.

[0016] The first telescopic actuator 4 and the second telescopic actuator 5 are preferably hydraulic cylinders, and can also be pneumatic cylinders. Depending on the width of the operating platform, the number of the first telescopic actuator 4 and the second telescopic actuator 5 can be one or two. In this embodiment, the number of the first telescopic actuator 4 and the second telescopic actuator 5 are both two, and they are symmetrically arranged on both sides of the operating platform. When the width of the operating platform is relatively short, the number of the first telescopic actuator 4 and the second telescopic actuator 5 can both be one, and the position can be set in the middle of the operating platform.

[0017] The working principle of the utility model is as follows: the first telescopic drive 4 and the second telescopic drive 5 cooperate with each other to switch the standing platform 2 to be raised and folded flat on the top of the frame 1, as follows:

[0018] like Figure 1 As shown, during the process that the first telescopic driver 4 extends to a predetermined stroke and the second telescopic driver 5 retracts to a predetermined stroke, the transition connection frame 3 flips forward to drive the standing platform 2 to rise, and the standing platform 2 flips forward to a horizontal state;

[0019] like Figure 2 As shown, when the second telescopic drive 5 is retracted to a predetermined stroke and extended to a predetermined stroke, the standing platform 2 and the transition connection frame 3 are respectively flipped backwards to be laid flat on the top of the frame 1 in sequence.

[0020] In addition, through the cooperation between the first telescopic drive 4 and the second telescopic drive 5, the height of the standing platform 2 can be arbitrarily adjusted within a certain stroke (the second telescopic drive 5 drives the standing platform 2 to a horizontal state, and adjusting the telescopic length of the first telescopic drive 4 can adjust the height of the standing platform 2), which makes it convenient for operators to use while greatly reducing the size of the operating platform.

[0021] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
