Abstract
An auxiliary device for assembling a spiral system of a large vertical mill comprises a frame top beam, two frame upright posts which are respectively connected to two sides of the frame top beam and a diagonal bracing support at the back of the frame; the frame top beam is provided with an open structure and is connected with a stiffening beam; the back of the frame is connected between the two frame columns in a diagonal pulling supporting mode. The utility model discloses not only can guarantee that the screw rod is in a stable vertical state, can greatly improve the efficiency of welt equipment moreover, guarantee installation quality, improve operational environment, reduce the safety risk.
Description
Technical field:
The utility model belongs to a kind of plant equipment, the servicing unit of particularly a kind of large-scale vertical mill spiral system assembling.
Background technology:
In auger grinding machine, the liner plate that spiral system is spun on screw rod both sides by screw rod and symmetrical disk forms.Concerning large-scale vertical auger grinding machine, screw rod and liner plate all need Assembling to become to be integrated, usually in liner plate assembling process, only use driving that screw rod is installed liner plate one by one after ground rotation to correct position, not only operating efficiency is low, and is difficult to the gap length intuitively between observation liner plate.Meanwhile, because screw installment state is vertical in form, need after assembling to use truck crane to coordinate driving to overturn, turn increase construction cost and Hoisting Security risk like this.
Summary of the invention:
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and a kind of servicing unit of large-scale vertical mill spiral system assembling is provided, this device not only can ensure that screw rod is in a stable plumbness, and can greatly improve liner plate assembling efficiency, ensure installation quality, improve work situation, reduce security risk.
As above conceive, the technical solution of the utility model is: a kind of servicing unit of large-scale vertical mill spiral system assembling, is characterized in that: comprise framework back timber, be connected to two upright of frame of framework back timber both sides and framework oblique pull support behind; Described framework back timber is shaped with unenclosed construction, framework back timber is connected with buttress brace; The oblique pull support and connection behind of described framework are between two upright of frame.
Above-mentioned unenclosed construction adopts active blade structure.
Above-mentioned buttress brace is selected the H profile steel of 400 × 300 and is connected with framework back timber by high-strength bolt.
The length of above-mentioned buttress brace is identical with framework back timber length.
The H profile steel of 300 × 300 selected by said frame column.
The utility model has following advantage and good effect:
1, the utility model framework back timber buttress brace selects the H profile steel of 400 × 300, and is connected with framework back timber by high-strength bolt, and the length of frame roof buttress brace is identical with frame roof structure length, because this reducing security risk.
2, the utility model framework back timber is shaped with unenclosed construction, can adjust its openings of sizes, for spiral system lifting and liner plate assembling provide working space.
3, the utility model upright of frame selects the H profile steel of 300 × 300, and the height of upright of frame should ensure spiral system distance from bottom ground 200-300mm, and uses the angle steel of 100 × 10 to form oblique pull with the stability of reinforced frame in framework behind and both sides.
The framework behind spacing that supports of oblique pull is determined by the diameter of screw rod and screw tip flange diameter, and object is the supporting zone that screw rod in order to ensure spiral system can pass in and out framework smoothly.
Accompanying drawing illustrates:
Fig. 1 is screw schematic diagram;
Fig. 2 is front view of the present utility model;
Fig. 3 is side view of the present utility model;
Fig. 4 is the B-B profile of Fig. 2;

Detailed description of the invention:
As in Figure 2-4: a kind of servicing unit of large-scale vertical mill spiral system assembling, comprise framework back timber 3, be connected to two upright of frame 4 of framework back timber both sides and framework oblique pull support behind 5.Described framework back timber is shaped with an active blade structure 2, framework back timber is connected with buttress brace 1 by high-strength bolt, this buttress brace selects the H profile steel of 400 × 300, and the length of buttress brace is identical with framework back timber length.The oblique pull support and connection behind of described framework are between two upright of frame, and the framework behind oblique pull spacing that supports 5 is determined by the diameter of screw rod and screw tip flange diameter, and object is the supporting zone that screw rod in order to ensure spiral system can pass in and out framework smoothly.
The H profile steel of 300 × 300 selected by said frame column 4, and the height of upright of frame should ensure spiral system distance from bottom ground 200-300mm, and uses the angle steel of 100 × 10 to form oblique pull with the stability of reinforced frame in framework behind and both sides.
Vertical ladder 6 is arranged on behind of the present utility model, with convenient working personnel upper and lower frames top, facilitates work high above the ground.
As shown in Figure 5: use procedure of the present utility model is:
1) servicing unit that large helical system is assembled is pressed shown in figure mono-assembled complete, and be positioned over the ground of firm stable, ensure that the servicing unit of large helical system assembling is in level.
2) active blade of support is opened, the screw rod of spiral system is vertically winched to frame roof superstructure certain altitude, and rotating screw bolt makes its first liner plate assembling position towards the front portion of support, to facilitate the assembling of liner plate, is then slowly dropped in frame roof structure by screw rod.
3) active blade is fastening, start to assemble first liner plate.
4) after first completes assembling, sling by screw rod and revolve turnback, the leading portion making the symmetric position of screw rod be in support carries out second and third sheet assembling.
5) repeat previous step successively, the symmetrical all liner plates installing spiral system, spiral system assemble is placed in servicing unit that large-scale vertical mill spiral system assembles and waits for that handling is entered in vertical mill.
6) during handling, first connect spiral system with hoist cable and make rope stressed, then active catch being opened, after allocation and transportation region security, then can carry out the handling of spiral system.
The utility model is according to spiral system architectural feature and size, use section steel manufacture, spiral system can be stablized the servicing unit being in plumbness.Spiral system can be positioned over a stable plumbness by the utility model, greatly facilitate observation and the adjustment in gap between the assembling of liner plate and liner plate, also the screw for assembling liner plate provides a suitable parking space, not only facilitate installment work, simultaneously also for liner plate examine and replace from now on provides desirable job platform.
