Technical Field

[0001] The utility model relates to the technical field of movable operating platforms, in particular to a movable operating platform for tunnel defect elimination. Background Art

[0002] The operating platform is an equipment device that helps construction workers improve their standing operating position during construction operations. It is an indispensable machine equipment in the construction process. For example, after the tunnel is penetrated, the next step is to eliminate tunnel defects, and the operating platform will be used.

[0003] Since the clearance inside the tunnel is about 7-9 meters high and the tunnel has curved sides, a construction operation platform is required to bear the load of pedestrians and small machinery. In modern construction processes, trolleys for excavation and trolleys for maintenance are generally used. However, in actual use, it is found that the above-mentioned trolleys are generally large in size and weight and are inconvenient to move.

[0004] Therefore, it is necessary to develop a movable operating platform for tunnel defect elimination to solve the above problems. Utility Model Content

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A movable operating platform for tunnel fault elimination, comprising:

[0008] Operating platform body;

[0009] At least three moving wheels; at least three moving wheels are installed at the bottom of the operating platform body;

[0010] Four mounting pipes; all four mounting pipes are arranged vertically and form a rectangular shape;

[0011] Multiple sets of rectangular frames; multiple sets of rectangular frames are installed parallel to each other along the length of the mounting tube; the rectangular frames are perpendicular to the mounting tube; each set of rectangular frames includes two parallel horizontal tubes and two parallel longitudinal tubes;

[0029] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, a movable operating platform for tunnel fault elimination includes:

[0031] Operating platform body 1;

[0032] Four moving wheels 2; the four moving wheels 2 are installed at the four corners of the bottom of the operating platform body 1;

[0033] Four mounting tubes 3; the four mounting tubes 3 are all arranged vertically and are surrounded by a rectangular parallelepiped;

[0034] Four sets of rectangular frames; four sets of rectangular frames are installed parallel to each other along the length direction of the mounting tube 3; the rectangular frames are perpendicular to the mounting tube 3; each set of rectangular frames includes two mutually parallel transverse tubes 4 and two mutually parallel longitudinal tubes 5;

[0035] The cantilever frame 6 is mounted on one side of two adjacent mounting tubes 3;

[0036] Four outer guard plates 13; four outer guard plates 13 are enclosed in a rectangular shape, and the four outer guard plates 13 are placed inside the cantilever frame 6;

[0037] The first platform plate 7 is laid on the top of a rectangular frame.

[0038] In another embodiment, Figure 1-2 As shown, the movable operating platform also includes a second platform plate 12 (the outer guard plate 13 is not provided at this time), and the cantilever cantilever frame 6 includes four sub-cantilever cantilever frames 6 distributed vertically, and the second platform plate 12 is horizontally laid on a sub-cantilever cantilever frame 6. The purpose of this arrangement is to place the workers and work equipment on the second platform plate 12 and the first platform plate 7 respectively; of course, in order to facilitate the construction of the workers, the setting heights of the second platform plate 12 and the first platform plate 7 can be freely matched as needed. The second platform plate 12 and the first platform plate 7 are preferably 5 cm thick, so that the safety of the construction workers on the operating platform body 1 is better guaranteed, and it is not easy to be stepped on and damaged, thereby improving the use quality of the operating platform body 1. The sub-cantilever cantilever frame 6 is formed into a right-angled triangular prism structure, and columns are provided on the outside of the four sub-cantilever cantilevers.

[0039] like Figure 1-2 As shown, the movable operating platform also includes two support rods 8, the lower ends of which are pressed against the ground, and the upper ends of the two support rods 8 are connected to two opposite sides of a set of rectangular frames. The provision of support rods 8 strengthens the connection between the operating platform body 1 and the inverted arch filling position on the tunnel floor, thereby making the operating platform body 1 more stable and less prone to shaking.

[0040] like Figure 1-2 As shown, the movable operating platform also includes two reinforcement pipes 10, which are arranged vertically and are respectively connected to the two longitudinal pipes 5 of the multiple sets of rectangular frames. The provision of the reinforcement pipes 10 improves the safety performance of the operating platform body 1, better ensures the safety of construction workers on the platform, and protects construction workers from falling.

[0041] like Figure 1-2As shown, the movable operating platform also includes two sets of diagonal braces, each formed in an X shape, and including two diagonal brace rods 9. The two sets of diagonal braces are respectively connected to the two longitudinal tubes 5 of the multiple sets of rectangular frames. The provision of the two diagonal braces 9 makes the entire frame of the operating platform body 1 more stable and less prone to shaking or loosening, thereby improving the safety of the operating platform body 1.

[0042] like Figure 1-4 As shown, the movable operating platform also includes four limiting devices 11, which include a mounting plate 111, a screw 112, a pressure plate 113, a knob 114, a reinforcement pad 115, and a nut 116. The top of the mounting plate 111 is connected to the bottom of the operating platform body 1, and a mounting hole is provided at the lower portion of the mounting plate 111. The nut 116 is fixedly installed in the mounting hole. The screw 112 and the nut 116 are threadedly engaged, and the first end of the screw 112 is connected to the middle of the knob 114, and the second end of the screw 112 is connected to the middle of the first side of the pressure plate 113. The pressure plate 113 and the knob 114 are respectively placed on both sides of the mounting plate 111. The second side of the pressure plate 113 is connected to a reinforcement pad 115, which is used to tighten the moving wheel 2. The reinforcement pad 115 is a rubber pad. After the operating platform body 1 is pushed to the working position in the tunnel via the moving wheels 2, the screw 112 is rotated via the knob 114, causing the pressure plate 113 to approach the moving wheel 2 under the drive of the screw 112, until the reinforcement pad 115 fixedly connected to the surface of the reinforcement plate contacts and squeezes the moving wheel 2. At this time, the position of the moving wheel 2 remains stable and is not prone to sliding, thereby ensuring the stability of the operating platform body 1 and preventing it from shaking, thereby ensuring the safety of the staff. The surface of the knob 114 is provided with several anti-slip protrusions. The setting of the knob 114 makes it easier to rotate the screw 112, thereby more conveniently limiting and fixing the position of the moving wheel 2, improving the convenience of using the limit device 11.

[0043] All pipes and frames in this application are made of φ48 steel pipes.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
