Description

Technical Field

[0001] The utility model relates to the technical field of tunnel maintenance, in particular to a tunnel maintenance operation lifting platform. Background Art

[0002] With the rapid development of the domestic transportation industry, the number of tunnels has increased year by year. The ancillary facilities in old tunnels need to be regularly inspected and replaced. However, the equipment in the tunnel is usually installed on the top of the tunnel, so a lifting platform is needed to transport the staff to the top for maintenance work.

[0003] However, the existing lifting platform has a limited working area. When workers standing on the platform cannot inspect the equipment next to them, they often lean out to inspect, which is prone to accidents. Alternatively, the entire platform can be moved by staff below, but in this case, frequent movements are required, which not only increases work intensity but also wastes time.

[0004] For this purpose, a lifting platform for tunnel maintenance operations is proposed. Summary of the invention

[0005] The purpose of the utility model is to provide a tunnel maintenance operation lifting platform to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tunnel maintenance operation lifting platform, comprising a bottom plate, a base is provided below the bottom plate, baffles are installed on both sides of the bottom plate, a screw rod is installed between the two baffles, and the screw rod passes through the base;

[0007] A threaded barrel is sleeved on the outer side of the screw rod, and the threaded barrel is rotatably connected to the inner side wall of the base. A motor for driving the threaded barrel to rotate is installed inside the base.

[0008] Preferably, external teeth are installed on the outer side of the threaded barrel.

[0009] Preferably, a gear is mounted on the output shaft of the motor, and the gear is meshedly connected with the external teeth.

[0010] Preferably, a plurality of support rods are evenly installed between the two baffles, and the support rods are slidably connected to the base.

[0011] Preferably: a frame is installed on the upper surface of the bottom plate, and a frame door is installed on one side of the frame.

[0012] Preferably: a protective net is installed on the frame and the frame door.

[0013] Preferably: a blocking plate is installed on the lower surface of the base, and a lifting scissors-fork machine is installed below the blocking plate.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the threaded barrel is driven to rotate by the motor, and then the screw rod is moved left and right through the threaded barrel, so that when the equipment next to it cannot be repaired, the platform can drive the staff to move, so that the staff can quickly complete the nearby maintenance work, avoiding the occurrence of overall movement, and also avoiding the staff from leaning out to carry out the maintenance process, thereby ensuring safety.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1-3 The utility model provides a technical solution: a tunnel maintenance operation lifting platform, comprising a bottom plate 5, a base 4 is provided below the bottom plate 5, baffles 3 are installed on both sides of the bottom plate 5, a screw rod 7 is installed between the two baffles 3, and the screw rod 7 passes through the base 4;

[0022] A threaded barrel 9 is sleeved on the outer side of the screw rod 7 , and the threaded barrel 9 is rotatably connected to the inner side wall of the base 4 . A motor 8 for driving the threaded barrel 9 to rotate is installed inside the base 4 .

[0023] like Figure 3 As shown: an external tooth 10 is installed on the outer side of the threaded barrel 9, and a gear 11 is installed on the output shaft of the motor 8, and the gear 11 is meshed and connected with the external tooth 10; through the above arrangement, the motor 8 drives the gear 11 to rotate, and then the gear 11 drives the threaded barrel 9 to rotate through the external tooth 10, and the rotation of the threaded barrel 9 can make the screw rod 7 move left and right.

[0024] like Figure 2As shown: a plurality of support rods 6 are evenly installed between the two baffles 3, and the support rods 6 are slidably connected to the base 4; through the above arrangement, the support rods 6 can make the bottom plate 5 move left and right more conveniently, and can also support the bottom plate 5 to increase the strength of the bottom plate 5.

[0025] like Figure 1 As shown: a frame 1 is installed on the upper surface of the base plate 5, a frame door 2 is installed on one side of the frame 1, and a protective net is installed on the frame 1 and the frame door 2; through the above settings, the frame 1 and the frame door 2 can protect the staff and avoid the situation where people fall.

[0026] like Figure 1 As shown: a blocking plate is installed on the lower surface of the base 4, and a lifting scissor-fork machine is installed below the blocking plate; through the above arrangement, the blocking plate can seal the opening below the base 4, and at the same time facilitate the installation of the scissor-fork machine.

[0027] Working principle: When mobile operations are required, the motor 8 drives the gear 11 to rotate, and the gear 11 can drive the threaded tube 9 to rotate through the external teeth 10. The rotation of the threaded tube 9 can make the screw rod 7 move left and right, and the movement of the screw rod 7 drives the base plate 5 to move left and right, thereby driving the staff on the base plate 5 to move left and right. At the same time, the support rod 6 can also increase the strength of the base plate 5 to avoid bending of the base plate 5.
