Description
Technical Field
The utility model belongs to the technical field of lifting devices, and particularly relates to a lifting device capable of avoiding occupying a travelling crane.
Background
A large number of main valves and main valve regulating valves are generally installed in a nuclear power station, and in order to ensure the safe operation of the nuclear power station, the valves need to be overhauled regularly so as to discover and treat the defects such as valve seat cracks and the like in the valves in time.
When the defects such as valve seat cracks and the like are treated, a special machining lathe and an automatic welding machine are usually required, and crane lifting is required in the processes of equipment installation, machining and disassembly. However, valve overhaul is generally performed in a overhaul window, driving resources are very intense, if driving is continuously used in the valve repair process, the overhaul critical path is prolonged, the overhaul period is prolonged, and grid connection time is delayed, so that huge economic influence is caused on the power generation benefit of the nuclear power unit.
In view of the foregoing, it is desirable to provide a lifting device that avoids the occupation of the crane.
Disclosure of Invention
The utility model aims at: overcomes the defects of the prior art and provides a lifting device capable of avoiding occupying the travelling crane.
In order to achieve the above object, the present utility model provides a lifting device comprising: the lifting trolley comprises four vertical supporting feet supported on the ground, a lower beam and a middle beam which are correspondingly connected with the adjacent vertical supporting feet, and a pair of upper beams positioned above the middle beam, wherein a lifting beam is arranged between the upper beams, and a lifting trolley capable of moving along the lifting beam is arranged on the lifting beam.
As an improvement of the lifting device, one side of the lifting device is left open.
As an improvement of the lifting device, the non-blank side of the lifting device is provided with a reinforcing rib.
As an improvement of the lifting device, the reinforcing ribs are triangular reinforcing ribs.

As an improvement of the lifting device, the surface of the lifting device is sprayed with antirust paint.
As an improvement of the hoisting device according to the utility model, the hoisting beam is movable along the upper cross beam.
As an improvement of the hoisting device according to the utility model, the parts of the hoisting device are detachably connected.
As an improvement of the lifting device, the components of the lifting device are connected by bolts.
Compared with the prior art, the lifting device can replace a crane to lift when the overhaul equipment and the valve component of the nuclear power station are disassembled and assembled in the overhaul process, so that the overhaul period is prevented from being increased due to the occupation of the crane, and the power generation benefit of the nuclear power unit can be provided.
Drawings
The hoisting device and the technical effects thereof are described in detail below with reference to the accompanying drawings and the detailed description, wherein:
fig. 1 is a schematic structural view of a lifting device according to the present utility model.
Detailed Description
In order to make the objects, technical solutions and technical effects of the present utility model more clear, the present utility model will be further described in detail with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented herein for purposes of illustration only and is not intended to limit the utility model.
Referring to fig. 1, the lifting device of the present utility model includes: the vertical support legs 10 supported on the ground, the lower beam 20 and the middle beam 30 correspondingly connecting the adjacent vertical support legs 10, and the pair of upper beams 40 positioned above the middle beam 30, the lifting beam 50 is installed between the upper beams 40, the lifting beam 50 is installed with a lifting trolley (not shown) movable along the lifting beam, and the lifting beam 50 is movable along the upper beams 40.
In the illustrated embodiment, in order to facilitate the entry and exit of the suspended objects, one side of the hoisting device is left open (left side in fig. 1 is left open, i.e. the left side in fig. 1 is not provided with the lower beam 20 and the middle beam 30), and at the same time, the non-left side of the hoisting device is provided with the reinforcing ribs 60, and the provision of the reinforcing ribs 60 helps to increase the overall rigidity and structural strength of the hoisting device. In the illustrated embodiment, the lifting brackets are provided with triangular ribs 60 on both the front and rear sides and the right side.
In order to facilitate storage when not in use, the components of the lifting device are detachably connected, for example, the components of the lifting device are connected by bolts. The arrangement is that each part is stored in a bulk way when being stored, and each part can be assembled when being used.
According to one embodiment of the utility model, in order to prolong the service life of the lifting device and prevent the lifting device from rusting, the surface of the lifting device is sprayed with an anti-rust paint, for example, the anti-rust paint can be sprayed for multiple times.
According to actual needs, after the design and manufacture of the hoisting device are completed, 1.1 times of dynamic load and 1.25 times of static load tests are carried out by a class agency. According to an embodiment of the hoisting device according to the utility model, the rated hoisting weight of the hoisting device is not less than 2T.
The lifting device can be suitable for lifting in the process of dismounting and mounting the machining tool and the welding tool in the process of repairing the valve seat cracks of the high-pressure valve of the steam turbine, so that driving occupation is avoided, and the repairing period is prevented from being increased. It should be understood that, although the present utility model is described in this specification with respect to repairing cracks in a valve seat of a high-pressure valve of a steam turbine, it should be understood that the present utility model is also applicable to other equipment repairing lifting requirements, especially lifting with 2T crane and below.
