Description

Technical Field

[0001] This utility model belongs to the field of concrete structure grinding, and specifically relates to a concrete structure grinding device. Background Technology

[0002] Concrete (abbreviated as concrete) is a composite material widely used in the construction industry. It is mainly composed of cement, sand, gravel and water mixed in a certain proportion. Concrete structure refers to concrete structure. After being poured and formed, the surface of the concrete structure usually has protrusions or burrs, which affects the dimensional accuracy of the structure and subsequent assembly. Therefore, it is usually necessary to grind the surface of the concrete structure.

[0003] When grinding concrete structures, manual grinding using a polishing machine is labor-intensive, so a concrete structure grinding device is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete structure grinding device, which solves the problems in the existing technology.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A concrete structure grinding device includes a worktable, a limit baffle fixed at the upper end of the worktable, and a sliding pressure plate on the worktable that can press the concrete structure against the limit baffle.

[0007] The workbench is equipped with a sliding support frame at its upper end, and a sliding slider is mounted on the support frame, with the sliding direction of the slider perpendicular to the sliding direction of the support frame. Below the slider is a liftable mounting base, on which a rotating grinding wheel is mounted, thereby grinding and polishing the concrete structure. Compared with manual grinding using a handheld polishing machine, this method significantly saves manpower.

[0008] Furthermore, the pressure plate is slidably connected to the worktable, and two first fixed plates are provided at the lower end of the worktable. A first lead screw that can rotate is provided between the two first fixed plates, and the first lead screw passes through the pressure plate and is threadedly connected to it.

[0009] Furthermore, the thread helix angle of the first lead screw is less than the equivalent friction angle.

[0010] Furthermore, the slider is slidably connected to the support frame, and the upper end of the support frame is provided with two second fixing plates. A rotatable second lead screw is provided between the two second fixing plates, and the second lead screw passes through the slider and is threadedly connected to it.

[0011] Furthermore, the thread helix angle of the second lead screw is less than the equivalent friction angle.

[0012] Furthermore, the support frame is slidably connected to the worktable, and two third fixing plates are provided at the upper end of the worktable. A rotatable third lead screw is provided between the two third fixing plates, and the third lead screw passes through the support frame and is threadedly connected to it.

[0013] Furthermore, the thread helix angle of the third lead screw is less than the equivalent friction angle.

[0014] Furthermore, a mounting plate is fixed to one side of the mounting base, and a spray pipe is fixed to the mounting plate; the spray pipe can spray water to the contact position between the grinding wheel and the concrete structure.

[0015] Furthermore, a support plate is provided on one side of the support frame, and a water tank is fixed on the support plate. The water tank and the spray pipe are connected by a flexible hose, and a water pump is provided in the water tank to pump the water in the water tank to the spray pipe, and finally spray it to the contact position between the grinding wheel and the concrete structure.

[0016] Furthermore, a second cylinder is fixed on the support frame, and a collar is fixed to the end of the drive shaft of the second cylinder. The hose passes through the collar and can pull the hose upward.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting a pressure plate assembly on the workbench to press the concrete structure onto the limiting baffle, and setting a sliding support frame in the grinding mechanism, a sliding slider is set on the support frame. The sliding direction of the slider is perpendicular to the sliding direction of the support frame. A grinding wheel assembly is set at the lower end of the slider, thereby grinding and polishing the concrete structure. Compared with manual grinding by hand-held polishing machine, it significantly saves manpower.

[0019] 2. By installing a water spray component on one side of the mounting base, water is sprayed onto the contact area between the grinding wheel and the concrete structure, thereby reducing the temperature of the grinding wheel and preventing excessive wear and tear that would affect the grinding effect.

[0020] 3. By setting a constraint component on the support frame, the hose is constrained and pulled to prevent the hose from drooping excessively and interfering with the grinding wheel, which would cause damage to the hose. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 As shown, the concrete structure grinding device includes a workbench 1, on which a concrete structure is placed and ground. A pressure plate assembly 2 is provided on the upper end of the workbench 1 to press and fix the concrete structure to ensure that the concrete structure remains stable during the grinding process.

[0031] like Figure 2 and Figure 3 As shown, a limit baffle 11 is fixed on the workbench 1, and the pressure plate assembly 2 includes a sliding pressure plate 21. The pressure plate 21 can move closer to the limit baffle 11 and press the concrete structure onto the limit baffle 11 to achieve the fixation of the concrete structure.

[0032] In this embodiment, the pressure plate 21 is slidably connected to the worktable 1. Two first fixing plates 22 are provided at the lower end of the worktable 1. A first lead screw 23 is rotatably connected between the two first fixing plates 22. The first lead screw 23 passes through the pressure plate 21 and is threadedly connected to it. By setting a motor on one of the first fixing plates 22 to drive the first lead screw 23 to rotate, the sliding of the pressure plate 21 can be achieved.

[0033] Furthermore, in order to ensure the stability of the pressure plate 21 pressing the concrete structure, the first lead screw 23 needs to have self-locking properties, that is, the thread helix angle of the first lead screw 23 is less than the equivalent friction angle.

[0034] Of course, the way to drive the pressure plate 21 to slide includes, but is not limited to, the first lead screw 23 and other structures in this embodiment. In other embodiments, the pressure plate 21 can be directly driven to slide by setting a hydraulic cylinder, telescopic rod and other linear drive components on the workbench 1, and the concrete structure can be pressed and fixed.

[0035] A grinding mechanism 3 is installed on the upper end of the workbench 1 to grind the concrete structure on the upper end of the workbench 1, and it saves manpower significantly compared to manual grinding with a handheld polisher.

[0036] like Figure 4 As shown, the grinding mechanism 3 includes a support frame 31 that can slide on the upper end of the worktable 1. A slider 32 that can slide is provided on the upper end of the support frame 31, and the sliding direction of the slider 32 is perpendicular to the sliding direction of the support frame 31. A grinding wheel assembly 33 is provided on the lower end of the slider 32 for grinding and polishing. By controlling the sliding of the support frame 31 and cooperating with the sliding of the slider 32, the concrete structure can be fully polished and ground.

[0037] like Figure 5 As shown, the grinding wheel assembly 33 includes a first cylinder 331 fixed to the lower end of the slider 32. The drive shaft end of the first cylinder 331 is fixed with a mounting base 332. The mounting base 332 is provided with a rotating grinding wheel 333 (the grinding wheel 333 is driven to rotate by a motor installed on the mounting base 332). Under the drive of the first cylinder 331, the grinding wheel 333 can descend to contact the concrete structure, thereby realizing grinding.

[0038] In this embodiment, the slider 32 is slidably connected to the support frame 31. The upper end of the support frame 31 is provided with two second fixing plates 311. A second lead screw 34 is rotatably connected between the two second fixing plates 311. The second lead screw 34 passes through the slider 32 and is threadedly connected to it. By setting a motor on one of the second fixing plates 311 to drive the second lead screw 34 to rotate, the sliding position of the slider 32 can be adjusted.

[0039] Furthermore, in order to ensure that the position of the slider 32 remains stable after adjustment, the second lead screw 34 needs to have self-locking properties, that is, the thread helix angle of the second lead screw 34 is less than the equivalent friction angle.

[0040] In other embodiments, the slider 32 can be directly driven to slide by providing linear drive components such as hydraulic cylinders and telescopic rods on the support frame 31.

[0041] In this embodiment, the support frame 31 is slidably connected to the workbench 1. Two third fixing plates 12 are provided on the upper end of the workbench 1. A third lead screw 4 is rotatably connected between the two third fixing plates 12. The third lead screw 4 passes through the support frame 31 and is threadedly connected to it. By setting a motor on one of the third fixing plates 12 to drive the third lead screw 4 to rotate, the sliding drive of the support frame 31 can be realized.

[0042] Furthermore, in order to ensure that the support frame 31 remains stable after the position is adjusted, the third lead screw 4 needs to have self-locking properties, that is, the thread helix angle of the third lead screw 4 is less than the equivalent friction angle.

[0043] In other embodiments, the support frame 31 can be directly driven to slide by setting linear drive components such as hydraulic cylinders and telescopic rods on the workbench 1.

[0044] A water spraying component 35 is provided on one side of the mounting base 333. The water spraying component 35 can spray water on the contact position between the grinding wheel and the concrete structure, thereby reducing the temperature of the grinding wheel and preventing the grinding wheel from overheating, which would increase wear and affect the grinding effect.

[0045] like Figure 6 As shown, the water spray assembly 35 includes a mounting plate 351 fixed to one side of the mounting base 333, and a spray pipe 352 fixed on the mounting plate 351. The spray pipe 352 can spray water to the contact position between the grinding wheel and the concrete structure. A support plate 312 is provided on one side of the support frame 31, and a water tank 353 is fixed on the support plate 312. The water tank 353 and the spray pipe 352 are connected and communicated through a hose 354. A water pump is installed in the water tank 353 to pump the water in the water tank 353 to the spray pipe 352, and finally spray it to the contact position between the grinding wheel and the concrete structure.

[0046] The presence of the hose 352 provides space for the lifting and horizontal movement of the grinding wheel assembly 33. However, when the grinding wheel assembly 33 approaches the water tank 353, the hose 352 may sag due to its excessive length, which may interfere with the grinding wheel 333 and cause damage. Therefore, in this embodiment, a constraint component 36 is provided on the support frame 31 to constrain and pull the hose 352 to avoid excessive sag of the hose 352 and cause interference damage.

[0047] like Figure 7 As shown, the constraint assembly 36 includes a second cylinder 361 fixed on the support frame 31. A collar 362 is fixed to the end of the drive shaft of the second cylinder 361. The hose 352 passes through the collar 362 and can be pulled upward to provide a constraint. Under the drive of the second cylinder 361, the collar 362 can be raised and lowered to release downward or pull upward on the hose 352 to adapt to different positions of the grinding wheel assembly 33.

[0048] Working principle:

[0049] A pressure plate assembly 2 is installed on the workbench 1 to press the concrete structure onto the limiting baffle 11. A sliding support frame 31 is installed in the grinding mechanism, and a sliding slider 32 is installed on the support frame 31. The sliding direction of the slider 32 is perpendicular to the sliding direction of the support frame 31. A grinding wheel assembly 33 is installed at the lower end of the slider 32, thereby grinding and polishing the concrete structure. Compared with manual grinding using a handheld polishing machine, this significantly saves manpower. A water spray assembly 35 is installed on one side of the mounting base 333 to spray water at the contact point between the grinding wheel and the concrete structure, thereby reducing the temperature of the grinding wheel and preventing excessive wear and tear that would affect the grinding effect. A constraint assembly 36 is installed on the support frame 31 to constrain and pull the hose 352, preventing the hose 352 from sagging excessively and interfering with the grinding wheel, which would cause damage to the hose.
