Description

Technical Field

[0001] The invention relates to the technical field of template grinding, and in particular to a self-propelled template grinding machine based on guiding technology. Background Art

[0002] During the production process of precast concrete box girders for bridges, the metal outer formwork provides a stable supporting structure for concrete pouring, and does not deform or move during the concrete pouring process, thereby ensuring the accurate shape and size of the precast box girder.

[0003] The surface of the polished metal outer formwork is flat and smooth, which is beneficial to improving the forming effect of the prefabricated box girder; and the guided linear grinding can effectively eliminate the defects such as unevenness, rust spots and burrs on the surface of the metal outer formwork, thereby reducing the pores and cracks on the concrete surface and improving the surface quality; at the same time, the guided linear grinding can also ensure the flatness and dimensional accuracy of the metal outer formwork surface, thereby helping to ensure the dimensional precision and accuracy of the prefabricated box girder. Therefore, during the casting process of the bridge concrete prefabricated box girder, in order to ensure the surface quality of the box girder, the metal outer formwork needs to be subjected to guided linear grinding.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] The present invention provides a self-propelled template grinding machine based on the guiding technology to grind the inner wall of the metal outer template. The shape of the metal outer template is as follows: Fig.10 As shown, the side end of the metal outer template is composed of a vertical part, an inclined part 1, an inclined part 2 and a horizontal part from top to bottom, wherein the inclined part 2 and the horizontal part on both sides of the metal outer template form a U-shaped structure.

[0038] See also Figure 1-Figure 4 A self-propelled template grinder based on guiding technology includes a mobile cart 1, two sliding grooves 11 are symmetrically provided at the front and rear ends of the upper end of the mobile cart 1, a plurality of universal wheels (not shown in the figure) are arranged at the lower end of the mobile cart 1, and the mobile cart 1 is an existing electric-controlled mobile device.

[0039] See also Fig.10During the specific work, the mobile pallet 1 is hoisted to the metal outer template to be polished by the existing hoisting equipment, and then the mobile pallet 1 is separated from the hoisting equipment.

[0040] See also Figure 1 and Figure 7 The self-propelled template grinder based on guiding technology also includes two side grinding devices 2 arranged in a central symmetrical manner. The two side grinding devices 2 are respectively connected to two sliding grooves 11. The side grinding device 2 includes a sliding block 21 slidably connected to the sliding groove 11. An inverted L-shaped connecting frame 22 is installed on the upper end of the sliding block 21, and a side grinding mechanism 23 is connected to the connecting frame 22.

[0041] During specific operation, the sliding block 21 is connected to the existing hydraulic cylinder. Before grinding, the two connecting frames 22 and the two side grinding mechanisms 23 are in a retracted state and are located above the mobile cart 1. At this time, the overall volume of the grinder is minimized, thereby reducing the space required for placing the grinder. After the grinder is hoisted onto the metal outer template, the two hydraulic cylinders are started, and the two hydraulic cylinders drive the two sliding blocks 21 to move toward the two side ends of the metal outer template until the sliding blocks 21 drive the side grinding mechanisms 23 to be in close contact with the inner wall of the side ends of the metal outer template through the connecting frames 22, and then the hydraulic cylinders are stopped.

[0042] See also Figure 1 and Figure 2 The self-propelled template grinder based on guiding technology also includes two guiding devices 3 arranged in a central symmetrical manner. The two guiding devices 3 are respectively connected to two connecting frames 22. The guiding device 3 includes a connecting mechanism 31 detachably connected to the upper end of the horizontal section of the connecting frame 22. The connecting mechanism 31 is connected to a first guiding mechanism 32, and the first guiding mechanism 32 is connected to a second guiding mechanism 33.

[0043] During specific operation, when the connecting frame 22 moves, it drives the first guide mechanism 32 and the second guide mechanism 33 to move toward the side end of the metal outer template through the connecting mechanism 31. The first guide mechanism 32 cooperates with the inclined part 1 of the metal outer template, and the second guide mechanism 33 cooperates with the inclined part 2 and the horizontal part of the metal outer template.

[0044] See also Figure 2 , Figure 6 and Figure 8 The connecting mechanism 31 includes a connecting plate 311 fixedly connected to the upper end of the horizontal section of the connecting frame 22 by a screw, and a plurality of evenly distributed buffer springs 312 are installed on the upper end of the connecting plate 311. A positioning column 313 fixedly connected to the upper end of the connecting plate 311 is arranged inside the buffer spring 312.

[0045] See also Figure 2 , Figure 5 and Figure 8The first guide mechanism 32 includes a strip plate 321 fixedly connected to the upper ends of the plurality of buffer springs 312, the strip plate 321 is slidably connected to the positioning column 313, two positioning holes 322 are symmetrically provided at the upper end of the strip plate 321, and a rectangular countersunk hole 323 is also provided at the upper end of the strip plate 321. The end of the strip plate 321 away from the second guide mechanism 33 is connected to a side guide branch chain 324, and a limited position branch chain 325 is connected to the side guide branch chain 324.

[0046] During specific operation, the connecting plate 311 is fixedly mounted on the connecting frame 22 through multiple screws before operation, and the connecting plate 311 drives the strip plate 321 to be connected to the connecting frame 22 through multiple positioning columns 313 and multiple buffer springs 312. When the connecting frame 22 moves, the strip plate 321 is driven to move toward the inclined portion of the metal outer template through the connecting plate 311 and the positioning columns 313, and the strip plate 321 drives the side guide chain 324 to be in close contact with the inner wall of the vertical portion of the metal outer template. The buffer spring 312 connected between the strip plate 321 and the connecting plate 311 can play a shock-absorbing role during grinding, effectively avoiding the phenomenon of loose parts due to vibration generated by the grinder during grinding, and reducing the influence on the guide during the grinding process.

[0047] See also Figure 5 , Figure 6 and Figure 8 The side guide branch chain 324 includes a sliding plate 3241 slidably connected to one end of the strip plate 321 away from the center of the moving cart 1, a second connecting spring 3242 is installed between the sliding plate 3241 and the strip plate 321, and a guide roller 3243 is rotatably connected to the lower end of the sliding plate 3241.

[0048] During operation, the strip plate 321 moves while driving the sliding plate 3241 to move. The sliding plate 3241 drives the guide roller 3243 to be in close contact with the inner wall of the vertical part of the corresponding metal outer template, and the lower end of the guide roller 3243 contacts the inner wall of the inclined part 1 of the metal outer template, and squeezes the second connection spring 3242. The resilience of the second connection spring 3242 ensures that the guide roller 3243 is always in close contact with the inner wall of the vertical part of the metal outer template, and even if the vertical part of the metal outer template is slightly deformed, it can be automatically compensated. The two guide rollers 3243 are in close contact with the two vertical parts of the metal outer template, achieving the effect of guiding the grinding. The guide rollers 3243 are controlled to rotate by a hydraulic motor.

[0049] See also Figure 5 , Figure 6 and Figure 8The limiting branch chain 325 includes two square plates 3251 symmetrically installed on the upper end of the sliding plate 3241. A rotating rod 3252 passes through the two square plates 3251 and is rotatably connected. A rotating frame 3254 is installed in the middle of the rotating rod 3252. The rotating frame 3254 has an L-shaped structure. The end of the rotating frame 3254 away from the rotating rod 3252 is rotatably connected to a guide roller 3255. Either end of the rotating rod 3252 is fixedly connected to the output shaft of a driving motor 3253, and the driving motor 3253 is fixedly connected to the corresponding square plate 3251.

[0050] During specific operation, before the driving motor 3253 works, the rotating frame 3254 drives the guide roller 3255 to be located above the sliding plate 3241. After the sliding plate 3241 drives the guide roller 3243 to be in close contact with the inner wall of the vertical part of the metal outer template, the driving motor 3253 is started. The driving motor 3253 drives the rotating frame 3254 to rotate downward through the rotating rod 3252. The rotating frame 3254 drives the guide roller 3255 to move to the outer wall of the inclined part of the metal outer template and contact the outer wall there. The guide roller 3255 cooperates with the guide roller 3243 to contact the metal outer template from the upper and lower directions, thereby effectively limiting the sliding plate 3241 in the vertical direction, avoiding the sliding plate 3241 from being offset due to excessive friction generated during grinding, and effectively ensuring that the side grinding mechanism 23 is in close contact with the inner wall of the metal outer template for grinding, thereby improving the stability of grinding.

[0051] See also Figure 2 , Figure 5 and Figure 8 The second guide mechanism 33 includes a guide rod 331 hinged on the lower side of one end of the strip plate 321 away from the corresponding side guide branch chain 324, a rotating branch chain 332 is connected between the guide rod 331 and the strip plate 321, and a sliding frame 334 is slidably connected to the end of the guide rod 331 away from the strip plate 321, a first connecting spring 333 is installed between the sliding frame 334 and the guide rod 331, and a ball 335 is rotatably connected to the end of the sliding frame 334 away from the corresponding first connecting spring 333.

[0052] See also Figure 2 , Figure 5 and Figure 8 The rotating branch chain 332 includes an arc rod 3321 installed on the side wall of the guide rod 331. The end of the arc rod 3321 away from the guide rod 331 slides through the rectangular countersunk hole 323 and is installed with a rectangular plate 3322. The rectangular plate 3322 is slidably matched with the rectangular countersunk hole 323. A return spring 3323 is installed between the guide rod 331 and the strip plate 321.

[0053] During specific operation, the guide rod 331, which is in a retracted state before operation, squeezes the reset spring 3323, and drives the guide rod 331 to move while the strip plate 321 moves. The guide rod 331 drives the ball 335 to move toward the inclined part 2 of the metal outer template through the sliding frame 334. When the sliding frame 334 drives the ball 335 to move out of the range of the moving pallet 1, the squeezed reset spring 3323 resets and drives the guide rod 331 to rotate. The guide rod 331 drives the rectangular plate 3322 to move through the arc rod 3321 until the rectangular plate 3322 enters the rectangular countersunk hole 323. At this time, the ball 335 is tightly attached to the inner wall of the connection between the inclined part 2 and the horizontal part of the metal outer template, thereby further realizing the function of using the shape of the metal outer template itself for grinding and guiding.

[0054] The two ball bearings 335 and the two guide rollers 3243 cooperate to realize the grinding guide function from multiple points, so that even if the metal outer template is partially deformed, the grinder as a whole is still under the grinding guide, avoiding deviation in the grinding direction and ensuring the accuracy of the grinding position.

[0055] See also Figure 1 and Fig. 9 The self-propelled template grinding machine based on guiding technology also includes a limiting device 4, which is connected to the middle of the upper end of the mobile cart 1. The limiting device 4 includes a hydraulic push rod 41 arranged in the middle of the upper end of the mobile cart 1. A Z-shaped plate 42 is installed at the upper end of the hydraulic push rod 41, and two limiting columns 43 are symmetrically installed on the lower side surfaces of both ends of the Z-shaped plate 42.

[0056] See also Figure 1 , Figure 8 and Fig. 9 The limiting device 4 also includes a mounting seat 44 installed in the middle of the upper end of the mobile cart 1. The upper end of the mounting seat 44 is fixedly connected to the lower end of the hydraulic push rod 41. Two counterweight blocks 45 are symmetrically arranged on the left and right sides of the mounting seat 44. The counterweight blocks 45 are placed on the upper end of the mobile cart 1.

[0057] During specific operation, the hydraulic push rod 41 is connected to an external hydraulic pump. After the two balls 335 are in close contact with the inner wall of the connection between the inclined part 2 and the horizontal part of the metal outer template, the hydraulic push rod 41 is started. The hydraulic push rod 41 drives the four limit columns 43 to move downward through the Z-shaped plate 42 and insert them into the corresponding positioning holes 322, thereby further limiting the lateral movement of the strip plate 321. At the same time, the Z-shaped plate 42 is in close contact with the upper end surface of the strip plate 321, and the upper end of the rectangular countersunk hole 323 is blocked, so as to limit the rotation direction of the rectangular plate 3322, which is conducive to maintaining the stable state of the guide rod 331 contacting the inner wall of the metal outer template through the sliding frame 334 and the ball 335. Secondly, the Z-shaped plate 42 can connect the two strip plates 321, improve the overall connection structural strength of the two guide devices 3, further increase the stability of the two balls 335 and the two guide rollers 3243 for grinding and guiding, and further increase the overall movement stability of the grinder through the counterweight block 45, which is beneficial to improve the grinding effect of the inner wall of the metal outer template.

[0058] See also Figure 1 and Figure 2 The self-propelled template grinder based on guiding technology also includes a bottom grinding device 5, which is connected to the front end of the mobile cart 1. The bottom grinding device 5 includes an L-shaped plate 51 installed at the front end of the mobile cart 1, and a bottom grinding mechanism 52 is installed at the lower end of the horizontal section of the L-shaped plate 51.

[0059] See also Figure 1 , Figure 5 and Figure 7 The side grinding mechanism 23 includes a fixed plate 231 fixedly installed on the connecting frame 22 through a connecting block, and the fixed plate 231 is in a V-shaped structure with an opening facing away from the vertical section of the connecting frame 22. A side grinding module 232 is installed at the end of the horizontal section of the connecting frame 22, and an upper bevel grinding module 233 and an upper arc grinding module 234 are installed on the lower side surface of the upper end of the fixed plate 231 in sequence, and a lower bevel grinding module 235 is installed on the side of the lower end of the fixed plate 231 away from the connecting frame 22.

[0060] See also Figure 1 and Figure 2 The bottom grinding mechanism 52 includes a bottom grinding module 521 installed at the lower end of the horizontal section of the L-shaped plate 51, and two lower arc grinding modules 522 are symmetrically installed at the lower end of the horizontal section of the L-shaped plate 51.

[0061] During specific operation, after the mobile cart 1 moves onto the metal outer template, the mobile cart 1 drives the bottom grinding module 521 and the lower arc grinding module 522 on the L-shaped plate 51 to move synchronously onto the metal outer template and cling to the inner wall of the horizontal part of the metal outer template, and then the moving connecting frame 22 and the fixed plate 231 drive the side grinding module 232, the upper inclined surface grinding module 233, the upper arc grinding module 234 and the lower inclined surface grinding module 235 to cling to the corresponding inner wall of the metal outer template, and the bottom The end grinding module 521, the lower arc grinding module 522, the side grinding module 232, the upper bevel grinding module 233, the upper arc grinding module 234 and the lower bevel grinding module 235 are all composed of a hydraulic motor and a grinding roller. Then, the bottom grinding module 521, the lower arc grinding module 522, the side grinding module 232, the upper bevel grinding module 233, the upper arc grinding module 234 and the lower bevel grinding module 235 are started to realize the function of grinding the inner wall of the metal outer template as a whole. The side grinding module 232 is for the inner wall of the vertical part of the metal outer template, the upper bevel grinding module 233 is for the inner wall of the inclined part one of the metal outer template, the upper arc grinding module 234 is for the inner wall of the connection between the inclined part one and the inclined part two of the metal outer template, the lower bevel grinding module 235 is for the inner wall of the inclined part two of the metal outer template, the bottom grinding module 521 and the lower arc grinding module 522 are respectively for the inner wall of the connection between the inclined part two and the horizontal part of the metal outer template and the inner wall of the horizontal part of the metal outer template.

[0062] During the grinding process, the external driving device drives the guide roller 3243 to rotate. The guide roller 3243 drives the two sliding plates 3241 to move through the friction between the guide roller 3243 and the upper side wall of the metal outer template, thereby driving the two strip plates 321 to move. The two strip plates 321 drive the two side grinding devices 2 to move through the connecting mechanism 31, thereby assisting the mobile cart 1 to drive the entire equipment to move, thereby grinding the inner wall of the entire metal outer template until the entire metal outer template is ground and the grinding is completed.
