The post-processing finished product workshop has a total of three floors with a small space, which requires breaking the house for hoisting, and there is little space for personnel construction.
[0003] Traditionally, the lifting of equipment in finished product workshops is usually done by breaking down the roof, lifting important large equipment into place, and then lifting the remaining equipment in and then transporting it back.

[0015] This implementation method redefines the correct equipment hoisting sequence and plan, selects the appropriate damaged house location, chooses the correct indoor hoisting point location, and determines the installation accuracy adjustment sequence of the line equipment to reduce the investment in personnel and equipment.
[0016] The technical solution claimed in the present invention is further clearly and completely described below through a relatively specific embodiment.
[0017] This embodiment takes a rare earth butadiene rubber and supporting equipment project as an example. Its post-processing finished product workshop mainly includes: 3 extrusion dehydrators, 3 expansion dryers, 9 vibration conveyors, 6 briquetting machines, 3 mechanical arms and more than 300 other equipment. Among them, the expansion dryer is 28 tons, the dehydrator is 19 tons, the equipment specifications are large, the installation distribution is dense, and the installation precision is high.
[0018] In this embodiment, the requirements for equipment lifting are as follows: (1) For equipment with lifting eyes and lifting rings weighing less than 2.5 tons, three specifications of round strand steel wire ropes with fiber core, nominal tensile strength of 1770MPa, nominal diameter of φ12, and length of 6m, 8m and 10m can be used. One steel wire rope can be used with two strands to lift equipment weighing less than 1 ton, and two steel wire ropes can be used with four strands to lift equipment weighing 1 ton to 2.5 tons. (2) For equipment weighing 1 ton to 2.5 tons with lifting holes, the above steel wire ropes can be used. Two steel wire ropes can be used with four strands. If necessary, the steel wire ropes should be equipped with soft protection to avoid damaging the surface of the equipment. (3) For parts weighing more than 1 ton without lifting eyes, lifting rings or lifting holes, the above steel wire ropes should be used. The steel wire ropes should be equipped with soft protection to avoid damaging the surface of the equipment. For parts weighing less than 1 ton, synthetic fiber flat slings or synthetic fiber flexible slings should be used, and both should meet the requirements specified in JB / T 8521-1997.
[0019] In this embodiment, the sides of the second and third floors are selected as the locations for breaking down the houses, and 2m×3m holes are chiseled out in each of them, which are used for hoisting the third-floor equipment and the second-floor equipment respectively.
[0020] The main equipment on the third floor includes extrusion dehydration machine, extrusion dehydration machine oil station, drying box exhaust fan, mist exhaust hood, buffer tank, and dust collector. The main equipment on the second floor includes expansion dryer, expansion machine reducer oil pump, vibration conveyor, drying box, hot water pump, washing water pump, wastewater pump, and heat exchanger. The main equipment on the first floor is the packaging line equipment, which mainly includes briquetting machine, roller conveyor, bagging machine, and robotic arm.
[0021] The selection of the location of each equipment lifting point is as follows: Figure 2-9 As shown. Among them, the important second-layer equipment expansion dryer, expansion drying box, and third-layer equipment extrusion dehydrator, because these equipment are large in size before dismantling, the overall equipment is particularly heavy, difficult to hoist, high in hoisting cost, long in construction period, and high in high-altitude construction risk, so we adopt the method of dismantling, hoisting and reinstallation for installation. After dismantling, the equipment does not exceed 15 tons, the size is greatly reduced, and an 80-ton crane can be used.
[0022] The expansion dryer weighs 28 tons as a whole, and is mainly composed of motor 1, coupling 3, and host 4. We disassemble the motor 1 and host 4 of the expansion dryer at coupling 3. After disassembly, the motor alone weighs about 13 tons, and the reducer and host weigh 15 tons. An 80-ton crane is used to slowly move the equipment close to the second-floor hoisting hole. After the tail of the host enters the second-floor floor, 6 electric tanks are used to catch the tail of the host and slowly transport it to the equipment foundation.
[0023] The extrusion dehydrator weighs 19 tons, consisting of a motor 1, a coupling 3, and a main machine 18. We also disassembled the motor and the main machine of the dehydrator. After disassembly, the single machine weighs about 9 tons, and the main machine weighs 10 tons. It is hoisted into the third-floor hoisting hole in the same way as the above-mentioned expansion dryer, and then transported to the side of the third-floor equipment foundation.
[0024] The drying box weighs 3.7 tons as a whole. The equipment is 9 meters long, 1.7 meters wide and 3.95 meters high. The equipment specifications and dimensions are too large. We split the drying box 9 into three small drying boxes at the connection. Each small drying box is 3 meters long, and then hoist the small drying boxes.
[0025] After hoisting the equipment on the second and third floors respectively between the floors, each equipment is hoisted and transported backwards.
[0026] The equipment on the second floor is transported by a 15-ton overhead crane, three 10-ton manual hoists, and six electric tanks in the factory. Two manual hoists are used to fix the equipment hoisting position at the front end of the equipment, and a 15-ton overhead crane is used to fix the hoisting position at the rear end of the equipment. Both sides are lifted at the same time. After the equipment is raised to the equipment foundation, another manual hoist is used to pull the equipment on the side and install it on the equipment foundation.
[0027] The three-layer equipment is hoisted into place by electric tanks and 15-ton cranes. The electric tanks are used to transport the equipment to the side of the equipment foundation, and then the cranes are used to hoist the equipment into place.
[0028] In this embodiment, the equipment of the post-processing packaging line is distributed on three layers. The transition equipment between each layer is the transition barrel 11. The axis of the three-layer equipment group must be in a straight line. Therefore, the second-layer equipment is installed first to determine the central axis position of the complete set of equipment, and then the transition hopper is gradually installed, and then the central axis position of the three-layer equipment is determined.
[0029] (1) From the second floor to the first floor: The motor 1 and the main body 4 of the expansion dryer are installed, such as Fig.10As shown, reconnect the motor and the main body with a coupling, lift the expansion dryer main unit 4 and motor 1 assembly into place according to the plan and elevation layout, and adjust their positions so that the center of the motor assembly conveying shaft is aligned with the center of the body input shaft. Use an inclined iron pad to adjust the motor shaft to horizontal under the machine base, and use a level to check whether the main shaft of the main unit is horizontal. If it is not horizontal, use an inclined iron pad to level the main shaft under the machine base. Use coupling 3 to connect the output shaft of the motor assembly and the input shaft of the main unit. The total runout tolerance of the two parts of coupling 3 is 0.04, and the axial non-straightness tolerance is 0.03 / 100. Re-tighten the positioning bolts of the motor, and finally install the coupling shield 2. After the production line is installed and adjusted, connect the static grounding wire, extend the anchor bolt B1 from the side of the reserved hole of the expansion dryer, place it in the position shown in the drawing and pre-tighten it, and perform secondary grouting. Requirements for secondary grouting of anchor bolts: The concrete for secondary pouring should be fine stone concrete one grade higher than the foundation concrete, or use expansive cement.
[0030] like Fig.11 As shown, the vibration conveyor support 6 is hoisted into place, and the lubricator support 7 is placed in place. After the production line is installed and adjusted, the static grounding wires of each machine are connected, and the foot of the vibration conveyor support 6 is welded to the embedded steel plate, and the foot of the lubricator support 7 is fixed with the expansion bolt B3.
[0031] like Fig.12 As shown, the drying box 9 is hoisted into place and adjusted to completely cover the vibration conveyor support 6. The exhaust system 8 is installed on the drying box 9 with bolts B2. After the production line is installed and adjusted, the foot of the drying box 9 is welded to the pre-buried steel plate on site.
[0032] like Fig.13 As shown, install the transition hopper 11 connecting the first and second layers, lift the transition hopper 11 into place, align the feed port with the discharge port of the drying box, install the transition hopper 11 on the briquetting machine 12 with bolts B4, and then install the subsequent packaging line equipment including roller conveyors, bagging machines and robotic arms.
[0033] (2) From the second floor to the third floor: like Fig.14As shown, place the main machine 18 of the extrusion dehydrator and the motor crane 1 in place according to the plan and elevation layout, adjust their positions, align the main machine feed bucket center with the upstream feeding center, align the motor shaft conveying center with the main machine input center, connect the motor output shaft and the main machine reducer input shaft with the coupling 3, and use shims to level the components to ensure that the coupling has a total runout tolerance of 0.04 and an axial straightness tolerance of 0.03 / 100. After the production line is installed and adjusted, extend the anchor bolt B1 from the side of the reserved hole of the extrusion dehydrator, place it in the position shown in the drawing and pre-tighten it, and perform secondary grouting. Requirements for secondary grouting of anchor bolts: The secondary poured concrete should use fine stone concrete one grade higher than the foundation concrete, or use expansive cement.
[0034] Then install the transition hopper 11 between the second and third layers, such as Fig.15 As shown, the upper end of the support barrel 13 is inserted into the discharge barrel of the extrusion dehydrator 18, and fixed with expansion bolts B5 to assemble the barrel. The straight barrel is installed on the expansion dryer 17 with bolts B4, and the inclined barrel support frame is fixed with expansion bolts B3. Then the washing glue tank and buffer tank are hoisted and installed.
[0035] After the extrusion dehydrator and expansion dryer are installed, the lubrication system is hoisted and placed in place according to the plan and elevation layout drawings, and its anchors are fixed with anchor bolts.
[0036] Finally, here is the installation method for the packaging line equipment: Use an infrared level to lay out the center axis of the briquetting machine, and install the equipment from front to back. If the equipment body blocks the infrared level, we use the method of leading the wire horizontally, then along the axis, and then leading the wire back. After each lead, use an ink fountain to pop out the lead-out line segment.
