Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a structural steel grinding device. Background Art

[0002] Structural steel is a form of steel. Structural steel refers to steel that meets specific strength and formability grades. Formability is expressed as the elongation after interruption in a tensile test. Structural steel is generally used for load-bearing and other purposes, in which the strength of steel is an important design criterion. Structural steel can be subdivided into: carbon structural steel, high-quality carbon structural steel, low-alloy high-strength structural steel, alloy structural steel, spring steel, weathering structural steel, easy-chip structural steel, non-quenched and tempered mechanical structural steel, etc.

[0003] Structural steel is often made into long strips of steel. As the bearing structure of buildings and equipment, if the structural steel is not properly preserved, rust often appears on its surface. At this time, the rust needs to be polished off. The existing method of rust removal of structural steel is generally to use a handheld grinder by the user to remove the rust on the structural steel using a grinding wheel. This rust removal method can only remove rust on one side of the structural steel, and the rust removal efficiency is low, which is not conducive to large-scale structural steel rust removal operations.

[0017] The following is a further detailed description through specific implementation methods:

[0018] like Figures 1 to 3 As shown:

[0019] A structural steel grinding device comprises a body 1 and a main control board. The main control board is installed in the body 1. The main control board is an existing mature technology and can be configured by the user as needed. A handle 2 is installed on the top of the body 1. The handle 2 is convenient for the user to hold the device. A control button 3 is installed on the handle 2. The control button 3 is used to control the operation of the device.

[0020] The device also includes a first grinding module and two second grinding modules. The first grinding module is installed at the end of the body 1, and the two second grinding modules are symmetrically installed on both sides of the body 1, so that when the device is working, the first grinding module can grind the top side of the structural steel, and the two second grinding modules are clamped on both sides of the structural steel, so that the multi-side grinding and rust removal operation of the structural steel can be achieved at the same time. The first grinding module and the second grinding module are prevented from contacting each other;

[0021] The second grinding module includes a second drive motor 6, a grinding wheel 7 and an extension arm 8. The second drive motor 6 is fixedly mounted on one end of the extension arm 8. The other end of the extension arm 8 is hinged to a limit groove 11 in the body 1 through a rotating shaft. The limit groove 11 is used to limit the swing angle of the extension arm 8 to prevent the second grinding module from swinging excessively. The grinding wheel 7 is mounted on the output shaft of the second drive motor 6, so that the second drive motor 6 can drive the grinding wheel 7 to rotate, and the grinding wheel 7 can perform grinding and rust removal operations on the surface of the structural steel.

[0022] The extension arms 8 of the two second grinding modules are connected by a pressure spring 10, and the pressure spring 10 passes through the machine body 1. Under the spring force of the pressure spring 10, the two second grinding modules can be squeezed toward the side close to the machine body 1, so that the grinding wheel 7 can better contact the surface of the structural steel.

[0023] Limiting grooves 11 are provided on both sides of the body 1, and the extension arm 8 is hinged in the limiting grooves 11 through a rotating shaft. The limiting grooves 11 are used to limit the swing range of the extension arm 8, thereby limiting the range of motion of the grinding wheel 7 to avoid mutual wear between the grinding wheel 7 and the first grinding module.

[0024] An adjusting bolt 9 is screwed into the extension arm 8, and the adjusting bolt 9 passes through the extension arm 8 and abuts against the side wall of the limiting groove 11. By adjusting the extended length of the adjusting bolt 9, the movable range of the telescopic arm at the limiting groove 11 can be adjusted, thereby adjusting the minimum clamping range between the two second grinding modules.

[0025] A knob is installed at one end of the adjusting bolt 9 away from the limiting groove 11 , and the knob is convenient for the user to turn the adjusting bolt 9 .

[0026] The first grinding module includes a first driving motor 4, which is installed at the end of the body 1. A grinding plate 5 is installed at the output shaft of the first driving motor 4. The first driving motor 4 is used to drive the grinding plate 5 to rotate, and the grinding plate 5 can grind the surface of the steel.

[0027] The specific real-time process is as follows:

[0028] When using the structural steel grinding device, the adjusting screws of the two second grinding modules can be adjusted according to the size of the structural steel. The adjusting screws push the telescopic arm from the limit slot 11 to adjust the opening range between the two telescopic arms, and then adjust the distance between the two grinding wheels 7; then the structural steel is inserted between the two grinding wheels 7, and the two grinding wheels 7 are pressed against each other on the side of the structural steel under the action of the pressing spring 10, and the grinding sheet 5 is attached to the top side of the structural steel. The user starts the device by operating the control button 3 on the handle 2, and the main control board controls the first drive motor 4 and the second drive motor 6 to start, and the first drive motor 4 and the second drive motor 6 respectively drive the grinding sheet 5 and the grinding wheel 7 to rotate, and the grinding sheet 5 and the grinding wheel 7 can grind and remove rust on the structural steel.

[0029] The structural steel grinding device works through the first grinding module to cooperate with the two second grinding modules installed on both sides of the body 1. The two grinding modules are attached to the structural steel through the pressure spring 10, and multiple surfaces of the structural steel are ground at the same time, which can effectively improve the grinding efficiency of the structural steel and reduce the work intensity of the user.
