DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 —5 further describes this application in detail.

[0025] The embodiment of the present application discloses a grinding device for secondary components of steel structures, which adopts the following technical scheme: a workbench 1, a back plate 14 is provided at the rear of the upper end surface of the workbench 1, a top plate 4 is provided at the top of the back plate 14, a rotating shaft 13 is rotatably connected inside the back plate 14, a grinding wheel 11 is provided at one end of the rotating shaft 13 extending toward the workbench 1, a clamping device is provided at the upper end surface of the workbench 1, a sealing cover 2 is provided at the upper end surface of the workbench 1, the sealing cover 2 covers the grinding wheel 11 and the clamping device in the sealing cover 2, a limiting portion 3 is provided at the top of the back side of the sealing cover 2, and a guiding portion 5 matched with the limiting portion 3 is provided on the upper end surface of the top plate 4. When in use, the secondary component of the steel structure is clamped and fixed by the clamping device, and then the sealing cover 2 is moved from the top plate 4 to the upper part of the workbench 1 , and cover the grinding wheel 11 and the clamping device inside the sealing cover 2, and then drive the rotating shaft 13 to rotate through the motor 12 arranged on the back of the back plate 14, and drive the grinding wheel 11 to rotate, so that the grinding wheel 11 grinds the secondary components of the steel structure. Since the entire grinding area is sealed by the sealing cover 2, a large amount of dust generated during grinding is confined to the inside of the sealing cover 2, which effectively prevents a large amount of dust from diffusing to the outside and affecting the working environment, effectively improves the working environment of the workers, and protects the health of the personnel; after grinding, lift the sealing cover 2 upward, and drive the limiting part 3 to move inside the guide part 5 until the sealing cover 2 moves to the upper end surface of the top plate 4. At this time, the secondary components of the steel structure are loosened by the clamping device and the secondary components are taken out.

[0026] In order to achieve the limiting and guiding of the limiting part 3 by the guiding part 5, the sealing cover 2 is moved from the top plate 4 to the upper end surface of the workbench 1 or the sealing cover 2 is moved from the upper end surface of the workbench 1 to the upper end surface of the top plate 4.

[0027] In this embodiment, the limiting portion 3 is a round rod, and the guide portion 5 includes a vertical portion and a horizontal portion that are perpendicular to each other. The vertical portion and the horizontal portion are connected guide grooves, and the round rod is located inside the guide groove. When the sealing cover 2 is located on the upper end surface of the workbench 1, the sealing cover 2 is first lifted upward to allow the round rod to move inside the guide groove of the vertical portion of the guide portion 5. When the round rod moves to the intersection of the guide groove of the vertical portion and the guide groove of the horizontal portion of the guide portion 5, the sealing cover 2 is pulled backward to allow the round rod to move inside the guide groove of the horizontal portion of the guide portion 5 until the entire sealing cover 2 is located on the upper end surface of the top plate 4, thereby achieving the purpose of temporarily placing the sealing cover 2.

[0028] In order to increase the stability of the round rod moving in the guide grooves of the vertical and horizontal parts of the guide portion 5, in the present embodiment, there are two guide portions 5, which are symmetrically arranged on the upper end surface of the top plate 4, and the two ends of the round rod are respectively inserted into the corresponding guide portions 5, the round rod and the sealing cover 2 are fixedly arranged, and an avoidance gap 10 is opened on the back of the sealing cover 2; when the sealing cover 2 is moved, the two ends of the round rod move in the guide grooves of the vertical and horizontal parts of the corresponding guide portion 5, respectively, thereby increasing the stability of the movement of the sealing cover 2; when the sealing cover 2 is moved from the top plate 4 through the limit portion 3 and the guide portion 5 to the upper end surface of the workbench 1, in order to avoid interference from the grinding wheel 11, the avoidance gap 10 opened on the back of the sealing cover 2 enables the grinding wheel 11 to enter the interior of the sealing cover 2.

[0029] In order to enable the round rod to change its direction of movement more smoothly when it moves to the intersection of the guide grooves of the vertical part and the horizontal part of the guide part 5, in this embodiment, the intersection of the vertical guide groove and the horizontal guide groove of the guide part 5 is chamfered. When the two ends of the round rod move to the intersection of the vertical guide groove and the horizontal guide groove of the guide part 5, the direction of movement can be changed more smoothly by chamfering.

[0030] In order to further realize the centralized treatment of the large amount of dust collected inside the sealing cover 2, in the present embodiment, the workbench 1 is a box with an open upper end, a grille plate 18 is provided on the upper inner wall of the box, and a clamping device is provided on the upper end surface of the grille plate 18. When the secondary components of the steel structure are ground by the grinding wheel 11, the generated dust and large particles of metal debris can enter the interior of the box through the grille plate 18.

[0031] In order to fix the secondary components when grinding the secondary components, in this embodiment, the clamping device includes two symmetrically arranged hydraulic telescopic rods 16, each hydraulic telescopic rod 16 has a clamping plate 17 at one end close to the hydraulic telescopic rod 16, and each hydraulic telescopic rod 16 has a fixing plate 15 at one end away from the hydraulic telescopic rod 16, and the bottom surface of each fixing plate 15 is fixed to the grid plate 18. When grinding the secondary components of the steel structure, the secondary components are first placed between the two clamping plates 17, and then the two clamping plates 17 are pushed to move closer to each other by the hydraulic telescopic rod 16 to clamp the secondary components, thereby fixing the secondary components.

[0032] In order to collect the floating dust generated during grinding, in this embodiment, an air collecting hood 6 connected to the interior of the box is provided on the right side of the box, an exhaust pipe 8 is provided on the right side of the air collecting hood 6, and an exhaust fan 7 is installed inside the exhaust pipe 8. During grinding, the exhaust fan 7 is started to vacuum the interior of the box through the exhaust pipe 8 and the air collecting hood 6, so that the floating dust generated during grinding enters the interior of the box through the grille plate 18 and is discharged through the exhaust pipe 8, and the exhausted gas is centrally processed.

[0033] In order to collect the large-particle metal debris generated when grinding the secondary components, in this embodiment, a collecting plate 19 inclined to the right and downward is provided inside the box body, and a chip removal hole is opened on the box body bottom plate on the left side of the bottom end of the collecting plate 19, and a chip removal bucket 9 is provided on the bottom surface of the box body bottom plate corresponding to the chip removal hole. The chip removal bucket 9 is connected with the interior of the box body through the chip removal hole. When grinding the secondary components, floating dust is generated and large-particle metal debris with heavier mass is also generated. The large-particle metal debris falls onto the collecting plate 19 through the grille plate 18. Since the collecting plate 19 is set inclined, the large-particle metal debris that falls onto the collecting plate 19 slides down from the collecting plate 19, and enters the interior of the chip removal bucket 9 through the chip removal hole of the box body bottom plate, and is discharged through the chip removal bucket 9 for centralized treatment; on the other hand, the suction effect of the exhaust fan 7 will also make the large-particle metal debris slide up and down on the collecting plate 19 faster.

[0034] The implementation principle of one embodiment of the present application is as follows: when in use, first place the secondary component of the steel structure between the two clamps 17, then push the clamps 17 through the hydraulic telescopic rod 16 to clamp and fix the secondary component, then move the sealing cover 2 on the top plate 4 to the upper end surface of the box body, so that the sealing cover 2 covers the grinding wheel 11 and the secondary component in the sealing cover 2, and then start the motor 12 to drive the grinding wheel 11 to rotate, so that the grinding wheel 11 grinds the secondary component, and the floating dust generated during grinding is confined in the interior of the sealing cover 2 by the sealing cover 2, and the large particles of metal debris generated at the same time fall onto the collecting plate 19 through the grille plate 18, and at the same time, the exhaust fan 7 is started to vacuum the interior of the box body through the exhaust pipe 8, so that the floating dust inside the sealing cover 2 enters the interior of the box body through the grille plate 18 and is discharged through the exhaust pipe 8, and then the exhausted gas is centrally processed, and the setting of the sealing cover 2 effectively prevents the floating dust from escaping into the external air, thereby ensuring the health of personnel.
