Description

Technical Field

[0001] The invention relates to the technical field of box beam outer mold grinding, and specifically proposes a self-propelled box beam outer mold grinding machine with a transfer trolley. Background Art

[0002] The polishing of the box girder outer formwork plays a vital role in the casting quality of the precast concrete box girder of the bridge. Polishing the box girder outer formwork can make the surface smoother and flatter, ensuring that the surface quality of the final poured concrete is more uniform and beautiful; it can also remove defects such as rust spots, sharp corners and burrs on the surface of the box girder outer formwork, and reduce the probability of pores and cracks on the concrete surface; the polished box girder outer formwork surface is smoother, which is conducive to the bonding between the concrete and the box girder outer formwork.

[0003] When grinding the outer formwork of the box beam, it is necessary not only to grind the horizontal section of the bottom inner wall of the outer formwork of the box beam, but also to grind the two side walls of the outer formwork of the box beam (such as Figure 2 As shown), in order to solve the problem that the grinding mechanisms on both sides and the horizontal section grinding mechanisms are large in size after being unfolded, and are difficult to move and transport, a box girder outer mold grinding machine is designed that can shrink the grinding mechanisms on both sides to the horizontal section grinding mechanisms. However, this can easily lead to instability of the grinding mechanisms on both sides. During the grinding process, the grinding mechanisms on both sides can easily shake due to vibration, thereby affecting the quality of grinding. Moreover, when the grinding mechanisms on both sides are moved after being shrunk, due to the large height dimensions of the grinding mechanisms on both sides, shaking can easily occur when only the bottom support connection is performed on the grinding mechanisms on both sides, thereby affecting the stability of the entire equipment.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] See also Figure 1 , Figure 4and Figure 5 A self-propelled box beam outer mold grinding machine with a transfer trolley comprises: a moving trolley 1, the moving trolley 1 is composed of a moving platform 2 and a plurality of traveling wheels 3 arranged in a rectangular shape connected to the bottom thereof, the top of the moving platform 2 is provided with two telescopic moving guide grooves 4 symmetrically arranged along its width direction, the bottom of the moving platform 2 is provided with an installation groove 5, the installation groove 5 is located between the two telescopic moving guide grooves 4, and the installation groove 5 and the two telescopic moving guide grooves 4 cut the moving platform 2 into a rectangular corrugated shape.

[0035] See also Figure 1 and Figure 3 A side wall grinding mechanism 6 is slidably connected in the telescopic movable guide groove 4. The two side wall grinding mechanisms 6 are arranged in a mirror image and move alternately. The side wall grinding mechanism 6 includes an inverted L-shaped frame 60 and a fixed plate 61. The shape of the fixed plate 61 is the same as the side wall shape of the box beam outer mold 9. A grinding group 62 for grinding the inner wall of the box beam outer mold 9 is arranged on the fixed plate 61.

[0036] See also Figure 4 A bottom grinding mechanism 7 for grinding the bottom inner wall of the box beam outer mold 9 is arranged in the mounting groove 5 .

[0037] See also Figure 1 , Figure 3 and Figure 4 A reinforcement locking mechanism 8 is provided on the top of the mobile platform 2, and the reinforcement locking mechanism 8 is located in the middle of the mobile platform 2. The reinforcement locking mechanism 8 includes a support seat 80 connected to the top of the mobile platform 2. The two side walls of the support seat 80 arranged along the width direction are both installed with guide rails 81. The two guide rails 81 are arranged in a staggered manner. The guide rails 81 are provided with a movable guide group 82 for horizontally guiding the corresponding inverted L-shaped frame 60. Both ends of the guide rails 81 are provided with mounting frames 83. The mounting frames 83 are hollow. The inverted L-shaped frame 60 A supplementary plate 84 is arranged between the vertical section and the fixed plate 61, and a latch reinforcement group 85 is arranged on the mounting frame 83. The two latch reinforcement groups 85 corresponding to the same guide rail 81 respectively plug and cooperate with the supplementary plate 84 on the same side wall grinding mechanism 6 after movement extension and movement contraction. An oblique abutment group 86 is arranged on both guide rails 81. The oblique abutment group 86 moves obliquely downward to press and reinforce the inverted L-shaped frame 60. A driving group 87 is arranged on the support seat 80 to drive the oblique abutment group 86 and the latch reinforcement group 85 to work synchronously.

[0038] When the two side wall grinding mechanisms 6 move and unfold, the supplementary plate 84 is aligned with the mounting frame 83 close to the side of the oblique abutment group 86, and then the driving group 87 drives the two oblique abutment groups 86 to move obliquely downward to press and reinforce the top corners of the two inverted L-shaped frames 60. At the same time, the driving group 87 drives the latch reinforcement group 85 to insert the supplementary plate 84 to reinforce the supplementary plate 84, which not only enables the side wall grinding mechanism 6 to obtain a double reinforcement effect, but also realizes the integrated reinforcement effect of the two side wall grinding mechanisms 6 and the mobile trolley 1, thereby greatly improving the overall stability of the equipment.

[0039] When the two side wall grinding mechanisms 6 move to the mobile trolley 1 and retract, the supplementary plate 84 is aligned with another mounting bracket 83, and then the drive group 87 is also started. The drive group 87 drives the oblique abutment group 86 and the latch reinforcement group 85 to lock and reinforce the side wall grinding mechanisms 6 again, so that the reinforced locking mechanism can lock the two retracted side wall grinding mechanisms 6 on the mobile platform 2 again as a whole, which not only reduces the space occupied by the equipment, facilitates the movement of the equipment, but also improves the stability of the equipment connection.

[0040] In summary, the same reinforcement locking mechanism can be used to integrally reinforce the two unfolded side wall grinding mechanisms 6 and the two retracted side wall grinding mechanisms 6, thereby improving the overall stability of the equipment.

[0041] See also Figure 3 , Figure 5 and Figure 8 The latch reinforcement group 85 includes two oblique slots 850 opened on the side wall of the supplementary plate 84 close to the support seat 80, the two oblique slots 850 are symmetrically arranged up and down, and the side wall of the mounting frame 83 away from the support seat 80 is obliquely and slidably connected with two plug plates 851 arranged symmetrically up and down. The two plug plates 851 are in an eight-shaped shape with a small diameter facing the inverted L-shaped frame 60, and the inclination direction of the oblique slots 850 corresponds one by one to the plug plates 851. An ear plate 852 is installed on the plug plate 851, and a return spring 853 is arranged between the ear plate 852 and the mounting frame 83. One end of the plug plate 851 located inside the mounting frame 83 is rotatably connected to a push roller 854, and a push assembly is arranged in the mounting frame 83. The push assembly is used to push the two plug plates 851 arranged symmetrically up and down to move synchronously.

[0042] See also Figure 8 The end of the plug plate 851 away from the mounting frame 83 is arc-shaped to facilitate the plug plate 851 to enter the oblique slot 850.

[0043] See also Figure 8The push assembly includes a rotating shaft 880 rotatably connected to the inner wall of the mounting frame 83, the axis of the rotating shaft 880 is parallel to the moving direction of the inverted L-shaped frame 60, a gear 881 is fixedly sleeved on the rotating shaft 880, and two moving bars 882 are slidably installed in the mounting frame 83, the two moving bars 882 are respectively located on both sides of the gear 881 and are staggered up and down, and the moving bars 882 are equipped with racks 883 meshing with the gear 881 for transmission, and the upper and lower moving bars 882 are respectively equipped with wedge blocks 884 for pushing the push rollers 854 connected to the upper and lower plug plates 851, and the wedge block 884 on the moving bar 882 on the side where the plug plate 851 is installed close to the mounting frame 83 rolls with the push roller 854 on the plug plate 851 located on the lower side.

[0044] When the two side wall grinding mechanisms 6 are expanded or contracted and the oblique slot 850 is aligned with the corresponding mounting frame 83, the driving group 87 presses down the moving bar 882 on the upper side. When the moving bar 882 on the upper side moves, the meshing transmission between the rack 883 and the gear 881 thereon drives the moving bar 882 on the lower side to move upward. While the two moving bars 882 move up and down alternately, they squeeze and push the upper and lower plug plates 851 to move through the wedge block 884. The plug plate 851 is obliquely inserted into the oblique slot 850. The oblique insertion of the upper and lower plug plates 851 can not only reinforce the inverted L-shaped frame 60 and the fixed plate 61 through the supplementary plate 84, but also limit the inverted L-shaped frame 60 and the fixed plate 61, thereby improving the stability and grinding quality during grinding.

[0045] See also Figure 3 and Figure 5 The oblique abutment group 86 includes an inverted L-shaped abutment seat 860, a support plate 861 is installed on the guide rail 81, the inverted L-shaped abutment seat 860 is slidably connected to the support plate 861 through an insertion rod 862, the insertion rod 862 is obliquely slidably connected to the support plate 861, the insertion rod 862 penetrates the support plate 861 and is rotatably installed with a pressing roller 863, a return spring 864 is installed between the side wall of the insertion rod 862 and the support plate 861, and a slot 865 is provided at the top of one end of the horizontal section of the inverted L-shaped frame 60 away from its vertical section.

Pressing plates 876 slidably connected to the straight groove 870 are installed on both sides of the lifting plate 873, and a pressing plate 877 is installed at the lower end of the pressing plate 876. The pressing plate 877 corresponds to the mounting frame 83 one by one, and the pressing plate 877 is slidably inserted into the corresponding mounting frame 83 and connected to the moving bar 882 located on the upper side.

[0047] The hydraulic cylinder 872 drives the lifting plate 873 to move downward, and the lifting plate 873 moves downward and drives the connecting rod 874 and the pressing plate 876 to move downward. When the connecting rod 874 drives the trapezoidal block 875 to move downward, when the inclined surface of the trapezoidal block 875 contacts the pressing roller 863 on the insertion rod 862, the trapezoidal block 875 squeezes the insertion rod 862 to move, and the pressing roller 863 rolls along the inclined surface of the trapezoidal block 875, and the insertion rod 862 drives the inverted L-shaped stop 860 to move until the inverted L-shaped stop 860 is in contact with the insertion rod 862. 0 is stuck at the corner of the inverted L-shaped frame 60, thereby tilting and supporting the inverted L-shaped frame 60 to prevent the side wall grinding mechanism 6 from moving along the telescopic movable guide groove 4 due to the grinding vibration force when the side wall grinding mechanism 6 is grinding the side wall of the box beam outer mold 9, thereby affecting the grinding effect of the side wall grinding mechanism 6 on the box beam outer mold 9; if both ends of the inverted L-shaped frame 60 are located on the moving trolley 1, the vertical section of the inverted L-shaped stop 860 is inserted into the card slot 865, and the side wall grinding mechanism 6 is also reinforced and limited.

[0048] When the pressure plate 876 moves downward, it drives the pressure plate 877 and the moving bar 822 connected to the pressure plate 877 to move downward. When the moving bar 882 moves downward, the wedge block 884 connected to it squeezes and pushes the plug plate 851 located on the upper side to move downward obliquely.

At the same time, the driving group 87 drives the latch reinforcement group 85, and the corresponding latch reinforcement group 85 is inserted into the supplementary plate 84 to reinforce the supplementary plate 84, so that the side wall polishing mechanism 6 obtains a double reinforcement effect, which greatly improves the stability during polishing. Then the mobile trolley 1 drives the bottom polishing mechanism 7 and the side wall polishing mechanism 6 to move, so that the two polish the inner wall of the box beam outer mold 9 at the same time.

[0058] After the grinding is completed, the driving group 87, the latch reinforcement group 85, and the oblique abutment group 86 are reset, and then the hydraulic cylinder 2 drives the side wall grinding mechanism 6 to move to the top of the mobile trolley 1, so that the two side wall grinding mechanisms 6 are retracted. At this time, the supplementary plate 84 is aligned with another mounting bracket 83 on the same guide rail 81, and then the driving group 87 drives the latch reinforcement group 85 and the oblique abutment group 86 to work again, so that the reinforcement locking mechanism can integrate and lock the two side wall grinding mechanisms 6 after the retraction again, which not only reduces the space occupied by the equipment, facilitates the movement of the equipment, but also improves the stability of the equipment connection.
