Dismantling method of large integral frame hydraulic press in low space factory building

Abstract

The invention discloses a method for efficiently dismantling a large-scale integrated framework hydraulic machine in a low workshop. The method is characterized by comprising the following steps of 1, carrying out preparatory work for dismantling a large-scale integrated framework hydraulic machine, and 2, by a truck-mounted double-machine hoisting crane allowing the load of 90t, displacing the hydraulic machine and putting the hydraulic machine on a load-trolley, wherein the step 2 concretely comprises the following steps of 1, hoisting the hydraulic machine by the truck-mounted double-machine hoisting crane and conveying it to a channel, 2, putting down the hydraulic machine, 3, putting the hydraulic machine on the load-trolley and 4, putting the hydraulic machine on a carrier vehicle by the truck-mounted double-machine hoisting crane so that dismantling of the hydraulic machine is finished. The method utilizes a hoisting and dismantling novel technology to solve the problem that the large-scale integrated framework hydraulic machine is dismantled difficultly in a low workshop, greatly improves construction efficiency, shortens stopping time of production (comprising rim and coating production line production) by 4 days, directly provides large economic benefits for owners, reduces a resource investment, and reduces a construction cost.

Description

technical field [0001] The invention relates to a dismantling operation method, in particular to an efficient dismantling method of a large integral frame hydraulic machine in a low space factory building. Background technique [0002] The hoisting operation of large-scale equipment in a closed factory building is very dependent on the outside world. Different construction environments and different owners' requirements will bring new challenges. The largest single-piece weight of the large integral frame hydraulic press equipment that needs to be relocated is 82 tons, and it needs to be dismantled in a closed workshop with an effective height of 15m. The narrow space has a huge impact on the construction. In addition, the construction period of similar domestic projects is generally 45 days. , and the owner requested to complete the relocation task within 30 days in order to realize the investment benefits as soon as possible. [0003] According to the regulations of Jianz...

Problems solved by technology

The largest single-piece weight of the large integral frame hydraulic press equipment that needs to be relocated is 82 tons, and it needs to be dismantled in a closed workshop with an effective height of 15m. The narrow space has a huge impact on the construction. In addition, the construction period of similar domestic projects is generally 45 days. , and in order to realize the investment benefits as soon as possible, the owner requires that the relocation task be completed within 30 days. The construction period is extremely tight, and the owner requires that the daily production of the spoke production line next to the equipment to be dismantled should not be affected when the equipment is removed and relocated.

[0003] According to the regulations of Jianzhi [2009] No. 87 document "Safety Management Measures for Highly Dangerous Subsection Projects", the demolition construction of this large integral frame hydraulic press belongs to a relatively dangerous subsection project exceeding a certain scale, and needs to be used Large-scale hoisting machinery and transport vehicles, but there is only one crane with a lifting capacity of only 16 tons in the closed workshop, which is far less than the weight of the equipment. Not only can it not undertake the lifting task alone, but it also cannot cooperate with a large truck crane Ability to lift and dismantle

Therefore, in the dismantling construction of the large integral frame hydraulic machine in this case, the working area is narrow, the construction conditions are complicated, and there are many safety hazards; the hydraulic machine equipment is heavy, the organization is difficult, and the construction cost is high, which brings greater risks to the project operation

[0004] Therefore, there are above-mentioned inconveniences and problems in the known efficient dismantling method of large integral frame hydraulic presses in low-space workshops.
