Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to a grinding device for assembled building matching structures. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where the required components and accessories are processed and manufactured, transported to the construction site, and then assembled and installed on site through reliable connection methods. Common steel supporting components include: steel beams, steel columns, steel trusses, and light steel structural wall panels, among which common steel beams are I-shaped, U-shaped, and T-shaped.

[0003] In prefabricated buildings, the grinding of matching components is an important step to ensure the quality of components and installation accuracy. The connection surfaces between components need to be polished flat to ensure a tight fit. The steel matching components produced by the factory are generally stored in the warehouse first, and then transported to the construction site when needed. During the storage and transportation process, rust and impurities will be generated on the surface of the steel beam, so it is necessary to carry out on-site grinding at the installation site of the prefabricated building. Usually, construction workers use angle grinders to grind the installation position and end faces of the steel beam surface. However, when manually controlling the angle grinder to grind the steel beam, it is difficult to control the grinding angle and grinding force to remain consistent, which can easily lead to uneven grinding of the steel beam surface. The grinding effect needs to be further improved. When more steel beams need to be polished, workers need to perform grinding operations for a long time, which will increase the intensity of manual work and reduce work efficiency, which will affect the subsequent assembly progress.

The bidirectional electric telescopic rod 23 is fixedly installed at the corresponding side end of the second slider 243. The bottom of the second lead screw 242 is coaxially fixedly connected to the top of the first lead screw 222. The lead of the thread on the first lead screw 222 is twice the lead of the thread on the second lead screw 242.

[0040] In the initial state, the steel beam is supported by the support blocks at the construction site, so that the parts of the front and rear ends of the steel beam that need to be polished are suspended in the air. Before polishing the steel beam, the U-shaped frame 1 is placed on the steel beam from the end of the steel beam, so that the horizontal section of the U-shaped frame 1 is placed on the top of the steel beam, the outer clamping plate 21 is located below the steel beam, and the two-way electric telescopic rod 23 is located on the inner side of the steel beam. By rotating the hand wheel to drive the first screw 222 and the second screw 242 to rotate, the outer clamping plate 21 and the two-way electric telescopic rod 23 can be moved upward, so that the outer clamping plate 21 is clamped on the steel beam. At the bottom of the beam, by setting the bidirectional electric telescopic rod 23 between the outer clamping plate 21 and the horizontal section of the C-shaped frame 1, and setting the lead of the thread on the first screw 222 to twice the lead of the thread on the second screw 242, when the outer clamping plate 21 moves upward, the bidirectional electric telescopic rod 23 will also move upward and always be in the middle position between the outer clamping plate 21 and the horizontal section of the C-shaped frame 1. The inner clamping plate 231 is pushed outward by the bidirectional electric telescopic rod 23, which facilitates the internal clamping and fixing of the steel beam, thereby improving the firmness of the fixation of the steel beam.

[0041] When fixing the I-shaped steel beam, the two outer clamping plates 21 are respectively located on the left and right sides of the lower part of the I-shaped steel beam, and the two bidirectional electric telescopic rods 23 are respectively located on the inner sides of the left and right ends of the I-shaped steel beam, so as to simultaneously clamp and fix the left and right sides of the I-shaped steel beam inside and outside (such as Figure 2When the U-shaped steel beam is fixed, the horizontal section of the U-shaped frame 1 cooperates with the outer clamping plate 21 on one side and the bidirectional electric telescopic rod 23 to clamp the U-shaped steel beam inside and outside (such as Fig.11 As shown); when fixing the T-shaped steel beam, the two outer clamping plates 21 are respectively located on the left and right sides of the lower end surface of the T-shaped steel beam. The two outer clamping plates 21 and the horizontal section of the U-shaped frame 1 cooperate to perform external clamping, and the two bidirectional electric telescopic rods 23 are respectively located on the left and right sides of the vertical section of the T-shaped steel beam, but only the inner clamping plates 231 connected to the lower ends of the bidirectional electric telescopic rods 23 are used to clamp the bottom of the T-shaped steel beam internally (as shown in FIG. Fig.12 as shown).

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 and Fig.12 The centering mechanism 3 includes an outer sleeve 31 fixedly mounted on the top of the horizontal section of the U-shaped frame 1, a bidirectional motor 32 is fixedly mounted on the inner middle part of the outer sleeve 31, and a third lead screw 33 is symmetrically mounted on the output shafts at the left and right ends of the bidirectional motor 32. The external thread of the third lead screw 33 is connected with a movable rod 34, and the movable rod 34 is slidably mounted inside the outer sleeve 31. The end of the movable rod 34 away from the center of the outer sleeve 31 extends to the outside of the outer sleeve 31 and is fixedly connected with an L-shaped push rod 35. A groove for the movable rod 34 and the L-shaped push rod 35 to move left and right is opened inside the side bracket 5. The horizontal section of the L-shaped push rod 35 slides through the inside of the U-shaped frame 1 and is fixedly connected with a side clamping plate 36. The opposite surfaces of the left and right side clamping plates 36 are rotatably mounted with ball bearings.

[0043] After the U-shaped frame 1 is placed on the steel beam, the bidirectional motor 32 drives the third lead screw 33 to rotate, so that the movable rod 34 can move toward the center of the outer sleeve 31. Then, the movable rod 34 drives the L-shaped push rod 35 and the side clamping plate 36 to move toward the center of the outer sleeve 31, so that the side clamping plate 36 can be clamped on the surface of the vertical section of the steel beam, and the U-shaped frame 1 can be fixed to the left and right to prevent the U-shaped frame 1 from moving left and right. The specific clamping states of the side clamping plate 36 on the I-shaped steel beam, the U-shaped steel beam and the T-shaped steel beam are as follows: Figure 2 , Fig.11 , Fig.12 shown.

[0044] See also Figure 1 , Figure 2 and Figure 5 The support mechanism 4 includes an elastic telescopic rod 41 fixedly mounted on the bottom of the side bracket 5 and symmetrically distributed front and back, a bottom plate 42 is fixedly connected between the bottoms of the front and rear elastic telescopic rods 41, and a universal wheel 43 symmetrically distributed front and back is fixedly mounted on the bottom of the bottom plate 42.

[0045] After the U-shaped frame 1 is installed on the steel beam, the universal wheel 43 is supported on the ground, and the elastic telescopic rod 41 can play the role of elastic support. By setting the support mechanism 4 to support the U-shaped frame 1, the pressure on the steel beam can be reduced and the stability of the steel beam when placed can be improved. At the same time, when the U-shaped frame 1 moves along the steel beam, the elastic telescopic rod 41 can adaptively expand and contract with the uneven changes of the ground, which is beneficial to ensure the stable position of the U-shaped frame 1 and the steel beam, and is also convenient for use at the installation site.

[0046] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 A locking assembly 66 for locking the rotating frame 61 is also installed on the side bracket 5. The locking assembly 66 includes an arc groove 661 opened on the side bracket 5. The center of the arc groove 661 coincides with the axis of the steering motor 62. A connecting block 662 is fixedly connected to the side of the rotating frame 61 close to the side bracket 5. The connecting block 662 is slidably installed in the inside of the arc groove 661. Two positioning holes 663 are opened on the side bracket 5, which are respectively located above and behind the steering motor 62. A positioning component 664 that is plugged into the corresponding positioning hole 663 is installed on the rotating frame 61.

[0047] When the U-shaped track 63 is to be rotated from a horizontal state to a vertical state, first release the lock of the positioning component 664 on the positioning hole 663 located above the steering motor 62, and then drive the rotating frame 61 to rotate ninety degrees counterclockwise through the steering motor 62 to rotate the U-shaped track 63 from a horizontal state to a vertical state. At this time, the positioning component 664 is aligned with the positioning hole 663 located behind the steering motor 62, and then the positioning component 664 is plugged into the positioning hole 663 located behind the steering motor 62, which can lock the rotating frame 61 and improve the stability of the rotating frame 61.

[0048] See also Figure 1 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10A locking component 67 for locking the electric slider module 64 is also installed on the C-shaped track 63. The locking component 67 includes a plurality of positioning holes 671 opened on the rear side of the horizontal section of the C-shaped track 63 and on the opposite sides of the two vertical sections. A positioning component 672 is installed on the mounting plate 641. The positioning component 672 includes a shell 6721 fixedly installed on the mounting plate 641. An iron stopper 6722 is installed inside the shell 6721 for sliding back and forth. A return spring 6723 is fixedly connected between the rear side of the iron stopper 6722 and the inner wall of the shell 6721. A positioning block 6724 is fixedly connected to the front side of the iron stopper 6722. The front end of the positioning block 6724 slides through the front of the shell 6721. The positioning block 6724 is plugged into the corresponding positioning hole 671. An electromagnet 6725 is fixedly installed on the rear side of the shell 6721. The positioning component 672 has the same structure as the positioning component 664.

[0049] When the position of the electric slider module 64 on the C-shaped track 63 is to be adjusted, the electromagnet 6725 is first energized to generate magnetic force, and the electromagnet 6725 is used to attract the iron baffle 6722 to move backward, so that the positioning block 6724 is released from the lock with the corresponding positioning hole 671, and then the electric slider module 64 moves. When the electric slider module 64 moves to the left or right side of the C-shaped track 63, the positioning block 6724 is aligned with the positioning hole 671 on the left or right side of the C-shaped track 63. At this time, the electromagnet 6725 is powered off and demagnetized, and the rebound force of the reset spring 6723 is used to push the iron baffle 6722 and the positioning block 6724 to reset, so that the positioning block 6724 is inserted into the corresponding positioning hole 671, and the electric slider module 64 can be locked again, thereby improving the stability of the electric slider module 64.

The end of the first connecting rod 745 away from the first rotating disk 744 is rotatably connected to the shaft rod 746.

[0051] See also Figure 6 , Figure 7 and Figure 8A vertical slot frame 731 is fixedly installed on the rear side of the second support frame 73, and the second slide 75 is slidably installed up and down inside the vertical slot frame 731. A first slide 732 is fixedly connected to the front side of the second support frame 73, and the first slide 732 is slidably installed left and right inside the support frame 1 72. The up and down moving component 76 includes a second turntable 761 rotatably installed on the rear side of the second support frame 73, and the second turntable 761 is coaxially fixedly connected to the toggle plate 742. The edge of the rear side of the second turntable 761 is rotatably connected to the second connecting rod 762, and the end of the second connecting rod 762 away from the second turntable 761 is rotatably connected to the bottom of the second slide 75.

[0052] The driving motor 741 drives the toggle plate 742 and the second rotating plate 761 to rotate, and then the second rotating plate 761 drives the second slide seat 75 to move up and down through the second connecting rod 762, so that the second slide seat 75 drives the grinder 77 to move up and down for grinding. At the same time, the toggle plate 742 drives the groove wheel 743 and the first rotating plate 744 to rotate intermittently. When the grinder 77 moves up and down once, the first rotating plate 744 rotates a certain angle, and then the first rotating plate 744 pushes the support frame 2 73 and the first slide seat 732 to move a distance to the right along the support frame 1 72 through the first connecting rod 745, so that the grinder 77 moves to the right for a distance and then moves up and down for grinding. After the grinder 77 grinds from left to right, the first rotating plate 744 will push the support frame 2 73 and the first slide seat 732 to move right along the support frame 1 72 through the first connecting rod 745, so that the grinder 77 grinds from right to left again until the grinder 77 returns to its initial position.

[0053] See also Figure 1-Figure 12 During specific use, step 1, in the initial state, the steel beam is supported by the support blocks at the construction site, so that the part of the front end of the steel beam that needs to be polished is suspended on the ground, and then the U-shaped frame 1 is installed on the steel beam. During installation, the horizontal section of the U-shaped frame 1 is placed on the top of the steel beam, the outer clamping plate 21 is located below the steel beam, and the two-way electric telescopic rod 23 is located on the inner side of the left and right ends of the steel beam. By rotating the hand wheel to drive the first screw 222 and the second screw 242 to rotate, the outer clamping plate 21 and the two-way electric telescopic rod 23 can be moved upward, so that the outer clamping plate 21 is clamped at the bottom of the steel beam.

[0054] Step 2: The bidirectional motor 32 drives the third lead screw 33 to rotate, so that the movable rod 34 can move toward the center of the outer sleeve 31. Then the movable rod 34 drives the L-shaped push rod 35 and the side clamping plate 36 to move toward the center of the outer sleeve 31, so that the side clamping plate 36 can be clamped on the surface of the vertical section of the steel beam, and the U-shaped frame 1 can be fixed to the left and right. Then the bidirectional electric telescopic rod 23 extends outward and pushes the inner clamping plate 231 to clamp the inner side of the steel beam.

[0055] Step three, in the initial state, the U-shaped track 63 is in a horizontal state, and the electric slider module 64 is located in the middle of the U-shaped track 63. When the end face of the steel beam needs to be polished, the electric push rod 71 pushes the support frame 1 72 to move backward, so that the grinder 77 is in close contact with the front end face of the steel beam. Then, the driving motor 2 741 drives the toggle plate 742 and the second turntable 761 to rotate, and then the second turntable 761 drives the second slide 75 to move up and down through the second connecting rod 762, so that the second slide 75 drives the grinder 77 to move up and down for polishing.

[0056] The first turntable 744 will push the support frame 1 73 and the first slide seat 732 to move right along the support frame 1 72 through the first connecting rod 745, so that the grinder 77 moves right for a distance and then moves up and down for grinding. After that, after each up and down movement of the grinder 77 for grinding, the support frame 2 73 will drive the grinder 77 to move right for a distance until the grinder 77 completely grinds the end face of the steel beam from left to right. After that, the first turntable 744 will push the support frame 2 73 and the first slide seat 732 to move right along the support frame 1 72 through the first connecting rod 745, so that the grinder 77 grinds again from right to left until the grinder 77 returns to the initial position, and then drives the support frame 1 72 to move forward through the electric push rod 71, so that the grinder 77 is separated from the surface of the steel beam.

[0057] Step 5. When the side of the steel beam needs to be polished, first energize the electromagnet 6725 to generate magnetic force, and use the electromagnet 6725 to attract the iron baffle 6722 to move backward, so that the positioning block 6724 is unlocked from the corresponding positioning hole 671, and then the electric slider module 64 slides along the C-shaped track 63 to move the polishing mechanism 7 from the front end of the steel beam to the side of the steel beam. At this time, the positioning block 6724 is aligned with the positioning hole 671 on the left or right side of the C-shaped track 63. Then the electromagnet 6725 is powered off and demagnetized, and the rebound force of the reset spring 6723 is used to push the iron baffle 6722 and the positioning block 6724 to reset, so that the positioning block 6724 is inserted into the corresponding positioning hole 671, and the electric slider module 64 is fixed again.

[0058] Step 6: Then the bidirectional electric telescopic rod 23 contracts inward to drive the inner clamping plate 231 to release the inner clamping of the steel beam, and then pushes the U-shaped frame 1 to move backward, so that the grinder 77 is aligned with the position on the side of the steel beam that needs to be grinded, and then the bidirectional electric telescopic rod 23 extends outward to push the inner clamping plate 231 to clamp the inner side of the steel beam, and then repeats steps 3 and 4 to grind the side of the steel beam.

[0059] Step 7. When the top of the steel beam needs to be polished, repeat the operation in step 5 to move the electric slider module 64 to the middle position of the steel beam, and then the positioning component 664 uses the same method as the positioning component 672 to unlock the positioning hole 663. Then the steering motor 62 drives the rotating frame 61 to rotate counterclockwise by 90 degrees, and rotates the U-shaped track 63 from a horizontal state to a vertical state. At this time, the positioning component 664 is aligned with the positioning hole 663 located behind the steering motor 62, and then the positioning component 664 is plugged into the positioning hole 663 located behind the steering motor 62, and the rotating frame 61 is locked to move the grinder 77 to the top of the steel beam, and then repeat step 6 to move the grinder 77 to the position on the top of the steel beam that needs to be polished, and then repeat steps 3 and 4 to polish the top of the steel beam.

[0060] Step 8. After the grinding of the steel beam is completed, the bidirectional electric telescopic rod 23 contracts inwardly to drive the inner clamping plate 231 to release the inner clamping of the steel beam, and then the hand wheel is rotated to drive the first screw 222 and the second screw 242 to rotate in the opposite direction, so that the outer clamping plate 21 can move downward, so that the outer clamping plate 21 loosens the clamping of the bottom of the steel beam, and then the bidirectional motor 32 drives the third screw 33 to rotate in the opposite direction, so that the movable rod 34 moves away from the center of the outer sleeve 31, and then the movable rod 34 drives the L-shaped push rod 35 and the side clamping plate 36 to move away from the center of the outer sleeve 31, so that the side clamping plate 36 loosens the centering clamping of the steel beam, and finally the U-shaped frame 1 is removed from the steel beam.
