[0013] The present invention also provides a rapid positioning method for a device that uses a positioning plate to assist in the installation and positioning of a steel component. The specific method includes the following steps:

[0014] Step 1, place the bottom of the lower I-shaped steel component through the lower positioning plate mechanism and place it at the bottom of the inner cavity of the placement seat. During the process, the lower I-shaped steel component first passes through the upper first I-shaped sleeve, and the first fiber brush removes the impurities adhered to the outer wall of the lower I-shaped steel component. Then start the first motor to drive the bidirectional screw to rotate, and the two sleeves approach each other, and the lower limit plates approach each other until the left and right sides of the lower part of the lower I-shaped steel component are clamped. Then start the dual-purpose oil pump for suction, and the oil pipe is connected to the external oil tank. The dual-purpose oil pump for suction draws hydraulic oil into the interior of the two limit cylinders through the oil pipe and the oil delivery pipe. As the hydraulic oil in the limit cylinder increases, the piston is pushed upward, and the upper limit plate mechanism and the lower positioning plate mechanism move up accordingly. When the upper limit plate mechanism and the lower positioning plate mechanism move up to the required height, the dual-purpose oil pump for suction stops working;

[0015] Step 2, then start the second motor to drive the screw rod to rotate, and under the limit of the limit rod, the internal threaded sleeve realizes movement in the left and right directions, and then pushes the upper limit plate, so that the two upper limit plates are close to each other to clamp the left and right sides of the upper part of the lower I-shaped steel component, so as to realize the clamping and fixing position between the upper and lower parts of the lower I-shaped steel component, and then the upper positioning plate assembly is sleeved on the lower part of the upper I-shaped steel component. During the process, the bottom of the upper I-shaped steel component first passes through the upper second I-shaped sleeve, and the second fiber bristles sweep away the impurities adhered to the outer wall of the upper I-shaped steel component. When the upper positioning plate assembly reaches the desired position, the adjusting block is screwed, and the external threaded rod rotates accordingly to push the square limit top block into the inside of the square cache slot, and the two square limit top blocks are close to each other to clamp the upper I-shaped steel component, so that the upper positioning plate assembly and the upper I-shaped steel component are locked;

[0016] Step 3: Pre-position by observing whether the infrared rays emitted by the infrared transmitter are at the top of the corresponding positioning groove. After the pre-positioning is accurate, use the external power mechanism to push the base upward, so that the lower I-beam steel member and the lower positioning plate mechanism move up at the same time, and insert several positioning columns into the corresponding positioning grooves to achieve fast and accurate positioning.

[0017] Preferably, a plurality of the positioning grooves are matched with a plurality of positioning columns.

[0018] Beneficial Effects

[0019] The invention provides a device for assisting steel component installation and positioning by using a positioning plate and a rapid positioning method.

[0020] Compared with the prior art, it has the following beneficial effects:

[0021] 1. A rapid positioning method for a device that uses a positioning plate to assist in the installation and positioning of steel components. Through the cooperation between the lower limit plate, the upper limit plate mechanism, the lower positioning plate mechanism and the upper positioning plate assembly, after limiting the lower I-shaped steel component, the position of the infrared emitter emitting infrared rays is observed for pre-positioning, and the positioning column is inserted into the positioning groove to achieve rapid and accurate positioning.

[0022] 2. A rapid positioning method for a device that uses a positioning plate to assist in the installation and positioning of steel components. Through the cooperation between the limiting cylinder, the piston, the adjusting plate and the dual-purpose suction oil pump, the position of the upper limiting plate mechanism and the lower positioning plate mechanism can be flexibly adjusted according to the length of the lower I-shaped steel component, thereby achieving stable limiting between the upper and lower parts of the lower I-shaped steel component with high flexibility.

[0023] 3. A rapid positioning method for a device that uses a positioning plate to assist in the installation and positioning of a steel component. Through the cooperation between the first I-shaped sleeve, the first fiber brush and the first ball, the first fiber brush can promptly remove impurities adhering to the surface of the lower I-shaped steel component. At the same time, the first ball can reduce the friction between the lower positioning plate mechanism and the lower I-shaped steel component, ensuring that the lower positioning plate mechanism is smoothly mounted on the outside of the lower I-shaped steel component, thereby improving work efficiency.

[0024] 4. A rapid positioning method for a device that uses a positioning plate to assist in the installation and positioning of a steel component. Through the cooperation between the second I-shaped sleeve, the second fiber bristles and the second ball bearings, the second fiber bristles can promptly remove impurities adhering to the surface of the upper I-shaped steel component. At the same time, the second ball bearings can reduce the friction between the upper positioning plate assembly and the upper I-shaped steel component, and smoothly adjust the position of the upper positioning plate assembly on the upper I-shaped steel component, which is highly practical.

5. A rapid positioning method for the device for assisting steel component installation and positioning using a positioning plate as claimed in claim 4, characterized in that: The method comprises the following steps: Step 1: Place the bottom of the lower I-shaped steel member (14) through the lower positioning plate mechanism (115) and place it at the bottom of the inner cavity of the placement seat (2). During the process, the lower I-shaped steel member (14) first passes through the upper first I-shaped sleeve (1154), and the first fiber brush (1155) removes impurities adhering to the outer wall of the lower I-shaped steel member (14). Then, the first motor (4) is started to drive the bidirectional screw rod (5) to rotate, and the two sleeves (6) are moved closer to each other, and the lower limit plate (7) is moved closer to each other until the left and right sides of the lower part of the lower I-shaped steel member (14) are clamped. Then, the pumping and suctioning oil pump (16) is started, and the oil pipe (18) is connected to the external oil tank. The pumping and suctioning oil pump (16) sucks the hydraulic oil into the inside of the two limit cylinders (10) through the oil pipe (18) and the oil delivery pipe (17). As the hydraulic oil in the limit cylinders (10) increases, the piston (111) is pushed upward, and the upper limit plate mechanism (113) and the lower positioning plate mechanism (115) move upward accordingly. When the upper limit plate mechanism (113) and the lower positioning plate mechanism (115) move upward to the required height, the pumping and suctioning oil pump (16) stops working; Step 2: Then start the second motor (1131) to drive the screw rod (1132) to rotate. Under the limit of the limit rod (1135), the internal threaded sleeve (1133) moves in the left and right directions, thereby pushing the upper limit plate (1134), so that the two upper limit plates (1134) are close to each other to clamp the left and right sides of the upper part of the lower I-shaped steel member (14), thereby clamping and positioning the upper and lower parts of the lower I-shaped steel member (14). Then, the upper positioning plate assembly (13) is sleeved on the lower part of the upper I-shaped steel member (15). During the process, the upper I-shaped steel member ( The bottom of the upper I-shaped steel member (15) first passes through the upper second I-shaped sleeve (133), and the second fiber brush (134) removes impurities adhering to the outer wall of the upper I-shaped steel member (15). When the upper positioning plate assembly (13) reaches the desired position, the adjusting block (1310) is screwed, and the external threaded rod (139) rotates accordingly, pushing the square limit top block (138) into the square buffer groove (137). The two square limit top blocks (138) are close to each other to clamp the upper I-shaped steel member (15), so that the upper positioning plate assembly (13) and the upper I-shaped steel member (15) are locked; Step 3: Pre-positioning is performed by observing whether the infrared rays emitted by the infrared emitter (1153) are at the top of the corresponding positioning groove (132). After the pre-positioning is accurate, the base (1) is pushed upward by an external power mechanism, so that the lower I-shaped steel member (14) and the lower positioning plate mechanism (115) are moved upward at the same time, and a plurality of positioning columns (1152) are respectively inserted into the corresponding positioning grooves (132) to achieve rapid and accurate positioning.
