Description
Technical Field
The utility model relates to the technical field of generator overhaul, in particular to an electric screw rod operating vehicle.
Background
The height of the large-sized hydraulic generator rotor is generally about 4 meters (including the buttresses), and the large-sized hydraulic generator rotor is generally overhauled by adopting a movable operation bent in the past, but the movable operation bent is poor in stability and can only be moved by manpower, and meanwhile, operators need to move up and down continuously in a non-closed space to complete equipment overhaul. Therefore, equipment such as a rotor is overhauled by adopting the movable operation bent frame, so that a certain safety risk exists, the efficiency is low, and the convenience of overhauling operation cannot be realized. In order to ensure the safety, high efficiency and convenience in overhauling the generator rotor and other equipment, a modular screw rod driving operation vehicle capable of automatically adjusting the height and moving and realizing the construction operation in a closed environment is required to be designed.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an electric screw rod working vehicle, which can freely adjust the overhaul height and the overhaul position.
In order to solve the technical problems, the utility model adopts the following technical scheme: an electric screw rod operation vehicle comprises a lifting platform, wherein four corners of the bottom of the lifting platform are fixedly connected with lifting blocks; the lifting device comprises a screw rod, the screw rod is in threaded connection with the lifting block and used for driving the lifting block to move up and down, and wheels are arranged at the bottom of the lifting device.
Preferably, the lifting devices are four, each lifting device comprises a base, a supporting frame is arranged on the base, a screw rod is arranged in the middle of the supporting frame, and a rotating motor for driving the screw rod to rotate is arranged in the base.
Preferably, a walking motor for driving the wheels to rotate is further arranged in the base.
Preferably, adjacent lifting devices are fixedly connected together through a first connecting rod and a second connecting rod.
Preferably, a fence is arranged at the edge of the lifting platform.
Preferably, the outer side surfaces of the support frame and the base are respectively provided with a first pulley and a second pulley.
Preferably, a hanging ring is arranged at the top of the supporting frame.
The utility model provides an electric screw rod working vehicle, which is convenient to move, firm and reliable in lifting, meets the convenience of maintenance and the safety of operators, and greatly improves the maintenance efficiency of a rotor. In addition, this device still sets up pulley, top at the side and sets up rings, has further strengthened the flexibility that the device removed.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a front view of the present utility model.
Detailed Description
As shown in fig. 1-2, an electric screw rod working vehicle comprises a lifting platform 1, wherein four corners of the bottom of the lifting platform 1 are fixedly connected with a lifting block 2; the lifting device comprises a screw rod 3, the screw rod 3 is in threaded connection with the lifting block 2 and is used for driving the lifting block 2 to move up and down, and wheels 4 are arranged at the bottom of the lifting device.
Preferably, the lifting devices are four, each lifting device comprises a base 5, a supporting frame 6 is arranged on the base 5, the screw rod 3 is arranged in the middle of the supporting frame 6, and a rotating motor 7 for driving the screw rod 3 to rotate is arranged in the base 5. The height of the base is 0.5m, and the length of the screw rod is 2.5m, so that the lifting platform 1 can move up and down between 0.5m and 3m, and the overhaul requirement is met.
Preferably, a walking motor 8 for driving the wheels 4 to rotate is also arranged in the base 5.
Preferably, adjacent lifting devices are fixedly connected together through a first connecting rod 9 and a second connecting rod 10.
Preferably, a fence 11 is arranged at the edge of the lifting platform 1. The fence height was set to 1.2m.
Preferably, the outer side surfaces of the support frame 6 and the base 5 are respectively provided with a first pulley 12 and a second pulley 13. The first pulley 12 and the second pulley 13 facilitate the movement of the device after falling down.
Preferably, a hanging ring 14 is arranged at the top of the supporting frame 6. The lifting ring 14 facilitates lifting of the device.
When the device is used, the lifting platform 1 is lowered to the position to be overhauled, an operator enters the lifting platform, then the rotating motor 7 is started, and the lifting platform is moved to the required height for overhauling. After one place is overhauled, the wheel 4 can be moved, the height of the lifting platform is adjusted again, and the next place is overhauled.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
