Description

Technical Field

[0001] The invention belongs to the technical field of equipment installation and construction, and in particular relates to a construction method for installing equipment without a pad iron. Background Art

[0002] When the bottom of a large unit is installed at the factory building, it is first hoisted on the foundation at the designated location. After the unit equipment is adjusted, a screw grouting machine is used to pour high-strength, non-shrinkage grouting material between the bottom of the equipment base and the foundation. The top screw position in the equipment base is reserved for non-grouting. When the grouting slurry reaches more than 75% of the design strength, the top screw is loosened, and the horizontality and shaft alignment are remeasured. After verification, the reserved position is grouted and becomes a secondary grouting layer after solidification. Then the large unit equipment can be installed.

[0003] In the prior art, during the grouting process using a screw grouting machine, the stirred slurry is first poured into the hopper of the screw grouting machine, and then the slurry is squeezed into the injection gun by the rotation of the screw in the installation tube, and then the slurry is injected under the base of the equipment through the injection gun. However, in the process of pouring the slurry into the hopper, in order to prevent some larger stones mixed in the slurry from entering the hopper, the larger stones are intercepted by a mesh plate installed in the hopper. When there are many larger stones in the mesh plate, the stones remain on the mesh plate, which will affect the speed at which the slurry falls into the hopper. Personnel need to use tools or directly use their hands to clean up the stones remaining on the mesh plate, which is inconvenient to clean and increases the cleaning time. In addition, multiple manual cleanings are required, which reduces the grouting speed. For this reason, we propose a construction method for installing equipment without a pad iron.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention has a cleaning mechanism designed to drive the vertical plate and the rubber scraper to move back and forth automatically through the transmission of the driving motor, the screw rod and the nut seat. The stones accumulated on the surface of the mesh plate can be scraped off without human intervention and fall into the side box for centralized collection. The cleaning process is carried out simultaneously with the grouting, avoiding shutdown interruptions caused by manual cleaning, ensuring the continuity of the grouting operation, and improving the construction efficiency. The trapezoidal teeth are inserted into the mesh, and the extrusion force of the trapezoidal structure is used to force the stuck stones to be cleared, avoiding the blockage of the mesh and affecting the slurry flow rate. The two cooperate to achieve dual cleaning of surface scraping and deep dredging. The rubber scraper can also be adjusted according to the degree of wear on the bottom of the rubber scraper to increase the utilization rate of the rubber scraper.

[0023] (2) The present invention is provided with an adjusting member which can dynamically adjust the elasticity of the connecting spring. When the elasticity of the connecting spring is weakened due to long-term use, the rotating spiral rod drives the mounting plate to move downward, compressing the connecting spring to restore or enhance its elasticity, thereby ensuring that the trapezoidal teeth at the bottom of the movable frame are always inserted into the mesh with sufficient squeezing force during the movement, effectively clearing the stuck stones, avoiding the reduction of cleaning efficiency due to the attenuation of the elasticity of the connecting spring, and extending the service life of the connecting spring.

[0024] (3) The present invention uses the designed auxiliary cleaning parts, through multiple sets of blowing heads, to use the high-pressure wind delivered by the blower to blow away the slurry attached to the surface of the rail and the screw in real time. This can effectively reduce the friction loss of the slurry against the rail and the screw, thereby extending the service life of key components such as the rail, screw, and nut seat. The auxiliary cleaning parts operate synchronously with the cleaning mechanism and can complete the cleaning during the grouting process of the equipment without stopping the machine or manual intervention, realizing "cleaning while working" and ensuring long-term stable operation of the equipment.

DETAILED DESCRIPTION

[0037] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figures 1-11 The present invention provides a technical solution: a construction method for installing equipment without a pad, comprising the following steps:

[0040] S1. After the equipment is transported to the site, it is hoisted to the foundation 6 at the designated location using a hoisting device. Grouting material is poured between the bottom of the equipment base 2 and the foundation 6 using a screw grouting machine, leaving the top screw 1 at the equipment base 2 unfilled.

[0041] S2: During the pouring process, the slurry is poured into the hopper 102 of the screw grouting machine, and the larger stones in the slurry are screened through the mesh plate 200;

[0042] S3. Start the drive motor 213 to drive the vertical plate 209 and the rubber scraper 210 to move back and forth on the mesh plate 200 to scrape off the larger stones on the mesh plate 200 and drop them into the side box 201. At the same time, the trapezoidal slotted teeth 217 that move back and forth clear the stones stuck in the mesh 208.

[0043] S4. When the grouting material reaches more than 75% of the design strength, loosen the top screw 1, fill the reserved position with grouting, and after solidification, form the secondary grouting layer 4 to complete the installation of the equipment base 2. By grouting, there is no need to set a pad under the equipment base 2 for support and installation, which saves costs.

[0044] The screw grouting machine in step S1 includes a hopper 102 and a mesh plate 200 installed on the hopper 102. Semicircular plates 203 are installed at the top of the front and back of the hopper 102. The arc surface of the top of the semicircular plate 203 facilitates the bottom of the trapezoidal gear 217 to contact the surface of the mesh plate 200. The mesh plate 200 has multiple groups of mesh holes 208. A cleaning mechanism is provided on the hopper 102, and the cleaning mechanism includes:

[0045] The concave plate 205 and the vertical plate 209 located in the hopper 102 and the side box 201 provided on the front and rear surfaces of the hopper 102, the bottom of the side box 201 is connected to the lower cover 206 via a rotating shaft, and the free end of the lower cover 206 is fixed to the side box 201 by fixing bolts, so that the lower cover 206 can be opened to take out the stones collected in the side box 201, and two groups of movable frames 204 are slidably provided on the vertical plate 209, and multiple groups of trapezoidal slotted teeth 217 are evenly distributed at the bottom of the movable frame 204 and along the length direction of the movable frame 204, and the bottom of the trapezoidal slotted teeth 217 can pass through the inside of the mesh 208, so as to clear the stones stuck in the mesh 208;

[0046] A rubber scraper 210 is fixedly provided at the bottom of the vertical plate 209. The rubber scraper 210 is close to the mesh plate 200 but does not contact it, so as to facilitate scraping off the stones on the mesh plate 200.

[0047] Two sets of extension plates 211 are fixedly provided on one side of the concave plate 205. The interior of the extension plate 211 is connected with a spiral column 215 through a thread. Two sets of mounting bearings are provided on the top of the vertical plate 209. The bottom of the spiral column 215 extends to the interior of the mounting bearing. The mounting bearing is composed of an inner ring and an outer ring. The inner ring is fixedly connected to the bottom of the spiral column 215, and the outer ring is fixedly connected to the vertical plate 209. By rotating the spiral column 215, the vertical plate 209 and the rubber scraper 210 at the bottom can be easily moved downward. When the bottom of the rubber scraper 210 is worn after long-term use, the rubber scraper 210 can be moved downward to be close to the screen 200, thereby increasing the service life of the rubber scraper 210.

[0048] Multiple groups of connecting springs 216 are fixedly provided on the movable frame 204, two groups of rails 202 are fixedly provided inside the side box 201, and the ends of the rails 202 pass through the inside of the concave plate 205, and two groups of clamping plates and a driving motor 213 are fixedly provided on the outside of the side box 201. A screw rod 207 is rotatably provided inside the clamping plate, and the working end of the driving motor 213 is fixedly connected to the end of the screw rod 207. A nut seat 212 is provided on the outside of the screw rod 207, and the nut seat 212 is fixedly connected to the concave plate 205 through the concave frame. The nut seat 212 moves back and forth on the screw rod 207, driving the rubber scraper 210 and the trapezoidal spline 217 to move, and the nut seat 212 is fixedly connected to the concave plate 205.

[0049] In summary, during the pouring process of the screw grouting machine, if some larger stones in the slurry poured into the hopper 102 are intercepted by the mesh plate 200, as the equipment continues to operate, a lot of stones are piled up on the mesh plate 200, which will affect the speed of the slurry entering the hopper 102. At this time, the stones on the mesh plate 200 are cleaned, and the driving motor 213 is started during cleaning. The driving motor 213 drives the screw rod 207 to rotate. At this time, the nut seat 212 outside the screw rod 207 moves toward the front direction of the equipment (that is, the front), and the nut seat 212 drives the concave frame to move, and the concave frame drives the concave plate 205 to move, and the concave plate 205 drives the extension plate 211 and the vertical plate 209 to move accordingly. At this time, the vertical plate 209 drives the rubber scraper 210 below to move, and the moving rubber scraper 210 scrapes the stones on the mesh plate 200 into the side box 201 located in the front of the hopper 102, and then the stones can be scraped into the side box 201;

[0050] When the concave plate 205 moves, it also drives the movable frame 204 and the multiple sets of trapezoidal splines 217 at the bottom of the movable frame 204 to move, and then the bottom of the trapezoidal spline 217 contacts the semicircular plate 203, and then the bottom of the trapezoidal spline 217 is squeezed by the semicircular plate 203 and begins to rise, driving the movable frame 204 to rise along with it, and then the bottom of the trapezoidal spline 217 contacts the mesh plate 200 and then inserts into the mesh 208, inserting the stone into the hopper 102, dredging the stone blocked in the mesh 208, and then after passing through the mesh 208, contacts the mesh plate 200 on the side of the mesh 208. At this time, the trapezoidal spline 217 and the movable frame 204 are squeezed by the mesh plate 200 and move upward, and then the bottom of the trapezoidal spline 217 is inserted into other mesh holes 208 and continues to remove the stones in other mesh holes 208. This is repeated. When the nut seat 212 moves forward to a suitable position, the drive motor 213 is reversed, driving the trapezoidal spline 217, the movable frame 204, the rubber scraper 210 and other structures to move toward the back of the equipment. This is repeated several times to scrape off the stones on the mesh plate 200 and dredge the stones stuck in the mesh holes 208.

[0051] Example 2

[0052] Based on Example 1, please refer to Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 The concave plate 205 is provided with an adjusting member for adjusting the elasticity of the connecting spring 216. The adjusting member includes a spiral rod 401 connected by a thread inside the concave plate 205 and a limiting rod 400 movably arranged in the concave plate 205. A fixed bearing is provided at the bottom of the spiral rod 401. The bottom of the spiral rod 401 is fixedly connected to the inner wall of the fixed bearing. A mounting plate 402 is fixedly provided on the outer wall of the fixed bearing. The bottom of the limiting rod 400 is fixedly connected to the mounting plate 402, and the top of the connecting spring 216 is fixedly connected to the mounting plate 402.

[0053] In summary, when the elasticity of the connecting spring 216 weakens after long-term use, the spiral rod 401 is rotated downward to drive the mounting plate 402 at the bottom to move. The mounting plate 402 moves downward to squeeze the connecting spring 216 downward, thereby increasing the elasticity of the connecting spring 216. At this time, the connecting spring 216 pushes the movable frame 204 and the multiple sets of trapezoidal splines 217 to move downward. In subsequent use, when the bottom of the trapezoidal spline 217 is inserted into the mesh 208, the squeezing force will increase, thereby increasing the squeezing force of the trapezoidal spline 217 on the stones stuck in the mesh 208, thereby increasing the dredging effect on the lion.

[0054] Example 3

[0055] Based on Example 2, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 10 , an auxiliary cleaning part is provided on the outside of the nut seat 212, and the auxiliary cleaning part includes a blower 300 fixed on the top of the nut seat 212 and a third ring tube 305 and a first ring tube 301 respectively sleeved on the screw rod 207 and the outside of the track 202. The inner walls of the third ring tube 305 and the first ring tube 301 are provided with multiple groups of blowing heads. During use, the blowing head on the first ring tube 301 can blow off some slurry attached to the track 202, reduce the amount of attachment, and reduce the amount of wear caused by the slurry on the inner wall of the vertical plate 209 and the concave plate 205 when they slide on the track 202. A pipeline 302 is provided between the blower 300 and the third ring tube 305 and the first ring tube 301;

[0056] Two groups of second ring tubes 304 are also provided on the outside of the screw rod 207. Multiple groups of nozzles are fixedly provided on the inner wall of the second ring tube 304. The blowing head on the third ring tube 305 first blows off the slurry attached to the outside of the screw rod 207, and then high-pressure water can be sprayed to the outside of the screw rod 207 through the nozzle to flush the slurry attached to the outside of the screw rod 207, thereby increasing the degree of cleaning of the slurry attached to the outside of the screw rod 207. A water pipe 303 is provided between the two groups of second ring tubes 304, and a joint is provided on the water pipe 303, which can be connected to an external water supply equipment.

[0057] In summary, when the concave plate 205 and the vertical plate 209 slide on the track 202 and the nut seat 212 moves on the screw rod 207, the blower 300 is turned on, and the blower 300 transmits high-pressure wind to the third ring pipe 305 and the first ring pipe 301 through the pipeline 302, and then blows the high-pressure wind to the screw rod 207 and the outer surface of the track 202 through the blowing heads on the inner walls of the third ring pipe 305 and the first ring pipe 301, respectively, to clean the air attached to the screw rod 207 and the track 202. 2, the slurry on the outer surface is blown off to reduce the degree of wear caused by the slurry on the track 202, the concave plate 205, the vertical plate 209, the outer surface of the screw rod 207 and the inner wall of the nut seat 212. At the same time, when the nut seat 212 moves, it also drives the two sets of second ring tubes 304 to move. At this time, the multiple sets of nozzles on the inner wall of the second ring tube 304 spray water to the screw rod 207 to flush the slurry on its outer surface again, thereby increasing the degree of cleaning of the slurry on the outer surface of the screw rod 207.

[0058] Example 4

[0059] Based on Example 3, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 11A mounting tube 101 is fixedly provided at the bottom of the hopper 102, a spiral blade is rotatably provided inside the mounting tube 101, a bracket 103 is provided outside the mounting tube 101, and a plurality of moving wheels are provided at the bottom of the bracket 103.

[0060] In this embodiment, a reduction motor 104 is provided on the mounting tube 101 , a connecting tube is provided at one end of the mounting tube 101 , an injection gun 100 is fixedly provided at the end of the connecting tube, and slurry is injected through the injection gun 100 .

[0061] In this embodiment, a pad 5 is provided on the foundation 6, and a top screw 1 is provided on the equipment base 2. The top screw 1 is connected to the inside of the equipment base 2 by a threaded connection. The fixing nut 3 is tightened downward to firmly fix the top screw 1 to the equipment base 2. The bottom of the top screw 1 contacts the surface of the pad 5, and the outside of the top screw 1 is connected to the fixing nut 3 by a thread. A secondary grouting layer 4 is poured between the equipment base 2 and the foundation 6. The secondary grouting layer 4 is located between the foundation 6 and the equipment base 2 in a reserved position that is not poured during the first pouring process, and then the slurry is poured at this position to form a secondary grouting layer 4. After the equipment is transported to the site, it is hoisted to the foundation 6 at the designated position by a hoisting equipment, and a piece of 100mmx1 is buried at the position corresponding to the top screw 1 (that is, the adjusting bolt) on the foundation 6. 00mm alignment reference pad 5, the thickness is selected according to the load of the equipment unit. After the equipment unit is leveled and aligned, the grouting material is poured into the space between the bottom of the equipment base 2 and the foundation 6 through a screw grouting machine, and the position of the top screw 1 at the equipment base 2 is reserved for non-grouting. During the grouting process, the slurry is poured into the hopper 102 in the screw grouting machine (when using this method for installation, the pad 5 should first be set at the corresponding position of the top screw 1 according to the specifications of the reference pad 5. The allowable deviation of its horizontality is 2mm, and the allowable deviation of the plane elevation of each pad 5 is ±5mm). After the unit equipment is in place, use tools such as a ruler, a level, and a plumb line to check whether the equipment entry and exit center are consistent with the drawing, and check the horizontality and verticality of the equipment. At the same time, the verticality of the anchor bolts and their orientation in the pit should be ensured.

[0062] The rotating unit equipment is aligned and calibrated to make the rotors of the unit reach the same axis center line or the axis position required in the cold state. Before adjustment, the axis center line of a rotor should be selected as the reference. Through alignment, the axes of the rotors of the unit are coaxial. The alignment of the unit when it is cold must be adjusted according to the cold alignment curve required by each unit. Through the alignment tool detection, the end face distance between the reference axis and the adjusted axis in the two half couplings, the deviation of axial tilt and radial displacement are obtained. The adjustment amount of each support of the adjusted axis and the adjustment direction of the machine body are determined by calculation or drawing method. Through adjustment, the unit reaches the cold alignment curve requirement.

[0063] If there is a centering defect in the rotating equipment, it will lead to a decrease in the torque transmission capacity of the equipment during operation, overheating and damage of the bearing components, damage and leakage of the sealing components, resulting in unstable operation of the unit, excessive vibration and other problems. Therefore, during the installation of the rotating equipment, ensure that its centering effect meets the relevant technical requirements. This method is suitable for the installation of large-scale unit equipment with a flat or frame-shaped base, and has the following characteristics: reducing the processing cost of shims and saving shim steel; there is no shim corrosion problem; simplifying the installation process, turning the secondary alignment into a single alignment, saving labor and time, and the process is easy to master; the unit installation speed is fast, the alignment and adjustment are convenient, the precision is high, the stability is good, and the unit has a long service life.

[0064] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
