The interim lifting operation platform of suspension type described in the utility model, comprise platform body, guardrail and extension leg, guardrail is arranged on the periphery of platform body, the center of platform body has an equipment circular hole is installed, the periphery that equipment is installed circular hole is evenly equipped with extension leg, hangs leg and is combined by vertical support bar and horizontal peg, and vertical support bar bottom is fixed on platform body, top fixing horizontal peg, arranges the bolt hole that is connected use with equipment connection flange on horizontal peg.
Use procedure is as follows:
Before equipment lifting, interim suspension type lifting operation platform is installed on the butt flange of equipment top, the horizontal peg of hanging leg in platform is connected by tie bolt with equipment top butt flange; Equipment rear operating personal in place arrives on interim lifting operation platform by hanging basket, and nut under bolt is all opened, and now main hoisting car hooks up, and lift cap is hung down.Because interim lifting operation platform adopts suspended structure, interim lifting operation platform can follow lift cap to be hung down together, and operating personnel can drop down onto on ground with interim lifting operation platform, thereby greatly reduces the lifting time of whipline.
Described vertical support bar top has regulating sleeve, one pin-and-hole is set on regulating sleeve, regulating sleeve is enclosed within horizontal peg outside, multiple Level tune pin-and-holes are set on horizontal peg, regulating sleeve is fixedly connected with by set pin with horizontal peg, be connected the spiro keyhole position of use in the end of horizontal peg with equipment connection flange, can regulate according to platform the position (hanging the horizontal length of leg) of horizontal peg apart from the distance at butt flange edge, equipment top and bolt situation, to adapt to the installation requirements of different size equipment.
Except aforesaid way, multiple bolts hole that are connected use with equipment connection flange can also be directly set on horizontal peg, directly directly choose the bolt hole of correct position according to platform apart from distance and the bolt situation at butt flange edge, equipment top, and by tie bolt, horizontal peg and butt flange are connected and fixed.
Described vertical support bar is made up of upper and lower two pole bodies, on the upper and lower body of rod, all arrange and highly regulate pin-and-hole, upper and lower two pole bodies are set in together and are fixedly connected with by set pin, can regulate according to the thickness of equipment top butt flange and lift cap, bolt length the height (hanging the height of leg) of vertical support bar.
Can regulate and hang leg height and the platform distance apart from butt flange edge, equipment top according to actual conditions by such scheme, thereby improve the degree of utilization of interim lifting operation platform, reduce the waste of resource.
The beneficial effect that the utility model compared with prior art had is:
The interim lifting operation platform operations of this suspension type is flexible and convenient to use, because interim lifting operation platform adopts suspended structure, interim lifting operation platform can follow lift cap to be hung down together, operating personnel can drop down onto on ground with interim lifting operation platform, thereby greatly reduce the lifting time of whipline, improved lifting efficiency; Extension leg is rational in infrastructure, can regulate and hang leg height and the platform distance apart from butt flange edge, equipment top according to actual conditions, thereby improve the degree of utilization of interim lifting operation platform, has reduced the waste of resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, guardrail; 2, platform body; 3, horizontal peg; 4, regulating sleeve; 5, set pin; 6, Level tune pin-and-hole; 7, the body of rod; 8, highly regulate pin-and-hole; 9, tie bolt; 10, butt flange; 11, equipment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the interim lifting operation platform of this suspension type, comprise platform body 2, guardrail and extension leg, guardrail is arranged on the periphery of platform body 2, and the center of platform body 2 has an equipment circular hole is installed, and the periphery that equipment is installed circular hole is evenly equipped with extension leg, hanging leg is combined by vertical support bar and horizontal peg 3, vertical support bar bottom is fixed on platform body 2, and top fixing horizontal peg 3 arranges the bolt hole that is connected use with equipment connection flange on horizontal peg 3.
Wherein: vertical support bar top has regulating sleeve 4, one pin-and-hole is set on regulating sleeve 4, regulating sleeve 4 is enclosed within horizontal peg 3 outsides, multiple Level tune pin-and-holes 6 are set on horizontal peg 3, regulating sleeve 4 is fixedly connected with by set pin 5 with horizontal peg 3, be connected the spiro keyhole position of use with equipment connection flange in the end of horizontal peg 3, can regulate according to platform the position (hanging the horizontal length of leg) of horizontal peg 3 apart from the distance at butt flange 10 edges, equipment top and bolt situation, to adapt to the installation requirements of different size equipment 11.Except aforesaid way, multiple bolts hole that are connected use with equipment connection flange can also be directly set on horizontal peg 3, directly directly choose the bolt hole of correct position according to platform apart from distance and the bolt situation at butt flange 10 edges, equipment top, and by tie bolt 9, horizontal peg 3 is connected and fixed with butt flange 10.
Vertical support bar is made up of upper and lower two pole bodies 7, on the upper and lower body of rod 7, all arrange and highly regulate pin-and-hole 8, upper and lower two pole bodies 7 are set in together and are fixedly connected with by set pin 5, can regulate according to the thickness of equipment top butt flange 10 and lift cap, bolt length the height (hanging the height of leg) of vertical support bar.
