Description
The application is a divisional application of the following applications, the application date of the original application: 10/2/2017, application number of original application: 201710074163.8, title of original application: a hoisting tool for an arc extinguish chamber of a tank type circuit breaker.
Technical Field
The invention relates to a hoisting tool for an arc extinguish chamber of a tank type circuit breaker.
Background
When the arc extinguish chamber of the tank type high-voltage circuit breaker is assembled, the cylindrical shell 7 outside the arc extinguish chamber is horizontally placed, the arc extinguish chamber with the cover plate at one end needs to be hoisted into the shell 7, the arc extinguish chamber of the high-voltage circuit breaker is heavy (1-2 tons), and a crane needs to be used for hoisting. Because the arc extinguish chamber of the high-voltage circuit breaker is integrally cylindrical, one end of the cylinder is connected with the cover plate, when the arc extinguish chamber is horizontally lifted, as shown in the attached drawing 1, the main body of the arc extinguish chamber lifting tool is a structural schematic diagram when the traditional lifting tool is lifted, the connecting frame 8 is connected onto the cover plate 31, the L-shaped suspension arm 81 upwards extends out of the connecting frame 8, the upper part of the suspension arm 81 is bent and then extends to the upper part of the middle of the arc extinguish chamber, and the suspension arm is provided with a main lifting. When the arc extinguish chamber is lifted, the arc extinguish chamber is lifted by a crane and a lifting rope to be connected with a lifting ring on the lifting arm 81 so as to realize the lifting of the arc extinguish chamber. The hoisting method has the following problems that once the hoisting tool is processed, the position of a main hoisting point and the weight of a connecting frame cannot be adjusted, once the hoisting point of the hoisting tool has slight deviation during processing or installation, the horizontality of hoisting the arc extinguish chamber cannot be ensured, and the tool cannot play a further adjusting role under the condition of uneven hoisting, needs to be manually assisted and adjusted by other modes such as knocking, pulling and the like, and even cannot be adjusted, so that the arc extinguish chamber is scratched and damaged during assembly, therefore, the tool is very difficult to hoist the arc extinguish chamber horizontally and ensure that the arc extinguish chamber horizontally enters the shell 7, and when the hoisting tool is used for hoisting the arc extinguish chamber, the bent part of the suspension arm of the tool bears great stress, the requirement on the strength of the suspension arm is very high, and the processing difficulty of the hoisting tool is increased.
Disclosure of Invention
The invention aims to provide a hoisting tool for an arc extinguish chamber of a tank-type circuit breaker, which aims to solve the technical problem that the arc extinguish chamber of the tank-type high-voltage circuit breaker is difficult to horizontally hoist when being installed in a shell.
In order to achieve the purpose, the technical scheme of the hoisting tool for the arc extinguish chamber of the tank type circuit breaker is as follows: including the connecting rod group that is used for with the apron connection of explosion chamber and install the counter weight in the one side of keeping away from the apron at connecting rod group, be equipped with on connecting rod group and/or the counter weight and be used for linking to each other with the regulation hoisting structure of main hoisting point with the explosion chamber leveling with hoisting machine structure. Through set up on counter weight or connecting rod group and adjust hoisting structure and hoist with the main hoisting point of cooperation arc extinguishing chamber apron, the weight of counter weight is calculated according to distance etc. in advance before main hoisting point lifts by crane, when recycling explosion chamber apron upper portion and lifting by crane as main hoisting point, the explosion chamber probably still has the incomplete horizontally condition of slope slightly, utilize this moment to adjust hoisting structure and carry out supplementary regulation, it is vital to the regulation of explosion chamber hoist and mount horizontality, make things convenient for the regulation of explosion chamber horizontal hoist and mount greatly, accelerate the hoist and mount process, and the improvement work efficiency, the difficult problem of hardly realizing explosion chamber horizontal hoist and mount when effectively solving the horizontal hoist and mount of tank circuit breaker explosion chamber.
Further, the position of the adjusting hoisting structure is adjustable in the length direction of the connecting rod group. The position of the adjusting hoisting structure is used as an auxiliary hoisting point for hoisting and adjusting the levelness, and the included angle between a hoisting rope extending from the hoisting mechanism and the horizontal plane is determined, the smaller the included angle is, the larger the force arm is when the hoisting rope pulls the balance weight, namely the adjusting hoisting structure can be adjusted in the length direction of the arc extinguish chamber, so that the arc extinguish chamber is more convenient to adjust in the levelness, and the adjustable range is larger.
Furthermore, adjust hoisting structure and be located connecting rod group is last, and connecting rod group includes along the screw rod that sets up on the connecting rod group length direction, adjust hoisting structure include with screw rod thread fit's swivel nut and establish the supplementary rings on the swivel nut.
