Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment, and in particular to a novel lifting device and welding production line. Background Technology

[0002] In the field of H-beam welding technology, the lifting seat is a key device for steel transfer and positioning, and its structural design directly affects the stability of the welding process. Existing lifting seats mainly consist of a base, reducer, lead screw, two position sensors, a receiving plate, a closed protective box, a protective sleeve, two fixed supports, two guide rods, and two guide tubes. Specifically, the closed protective box is fixed above the base, the reducer is installed on the top of the protective box, the lead screw passes through the protective box and forms a transmission connection with the reducer, and its top end is fixed to the receiving plate; the protective sleeve is fitted over the outside of the lead screw, with its top and bottom ends positioned by fixed supports; the two position sensors are installed on the upper and lower fixed supports respectively to monitor the lead screw travel; guide rods are connected to both sides of the receiving plate, and the guide rods form a sliding fit structure with the guide tubes on the base.

[0003] The working process of the lifting platform is as follows: When the steel (which has completed the first welding process and has a T-shaped structure consisting of a web perpendicular to the flange) is received, the reducer drives the lead screw to rotate, which drives the receiving plate to move upward along the guide rod until the receiving plate abuts against the web of the steel to achieve lifting; then the lifting platform moves as a whole to the adsorption station, the reducer drives the lead screw in the opposite direction to make the receiving plate descend, and after the web of the steel is connected to the adsorption equipment, the receiving plate continues to descend and detaches from the steel.

[0004] However, existing technologies have the following significant problems:

[0005] First, the position detection sensor (i.e., the probe that detects the height of the lead screw) is directly fixed to the fixed bracket with bolts. Under long-term vibration conditions, the bolts are prone to loosening, which can cause the probe to shift. Furthermore, due to the compact layout of the protective sleeve and the fixed bracket, multiple parts need to be disassembled when the probe is replaced, and a single maintenance takes more than 2 hours, resulting in low maintenance efficiency.

[0006] Second, the enclosed protective box adopts a fully welded and sealed structure, which houses the reducer and the lead screw transmission mechanism. However, when the parts inside the protective box are worn and need to be repaired, the connecting bolts between the base and the protective box need to be completely disassembled. Moreover, the internal space of the box is small, making tool operation difficult. The average time for replacing a single part is more than 4 hours, resulting in extremely poor maintenance convenience.

[0007] Third, when bearing T-shaped steel, the weight of the flange is usually 3-5 times that of the web, causing the center of force of the bearing plate to be biased to one side of the flange, which causes the lead screw to bear eccentric bending moment. This long-term eccentric load will accelerate the wear of the reducer gears, reduce the service life of the reducer, and frequent replacement of the reducer will increase production costs.

[0008] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as numerous disassembly and repair steps, low repair efficiency, easy damage to reducers, difficulty in adjusting the position of position detection sensors, and the need for complete shutdown during repairs, which extends the process time. Utility Model Content

[0075] Example 1

[0076] This embodiment relates to a novel lifting device of the present invention.

[0077] An illustrative embodiment of this utility model, such as Figure 2 As shown, a novel lifting device, applied in a welding production line, includes a base unit 100, a receiving unit 200, a transmission unit 300, a drive unit 400, a first protective unit 500, a second protective unit 600, a two-position detection unit 700, and a linear sliding unit 800. The receiving unit 200 is movably disposed on the upper part of the base unit 100 and is used to receive the web of steel. The transmission unit 300 is movably connected to the base unit 100, and its top end is connected to the receiving unit 200, driving the receiving unit 200 to reciprocate vertically. The drive unit 400 is drively connected to the transmission unit 300 and is used to drive the transmission unit 300 to reciprocate vertically. The first protective unit 500 is disposed between the base unit 100 and the drive unit 400, and is fitted with the transmission unit 300. The first protective unit 500 has at least one opening. The second protective unit 600 is fitted with the transmission unit 300, and the second protective unit 600 has at least two openings; a position detection unit is movably disposed in the second protective unit 600, at least one position detection unit 700 is disposed at the top of the second protective unit 600 and located inside the first protective unit 500, and at least one position detection unit 700 is disposed at the bottom of the second protective unit 600, for detecting the position of the transmission unit 300; a linear sliding unit 800 is disposed between the base unit 100 and the receiving unit 200, for assisting the receiving unit 200 in reciprocating motion in the vertical direction.

[0081] The method of using this utility model is as follows:

When the position detection unit 700 at the top of the second protection unit 600 recognizes the signal (such as the position detection unit 700 recognizing the bottom of the transmission unit 300), the drive unit 400 stops working. At this time, the receiving unit 200 is in the receiving position.

[0084] After receiving the second working signal, the drive unit 400 works, driving the transmission unit 300 to move vertically from top to bottom. When the position detection unit 700 at the bottom of the second protection unit 600 recognizes the signal (such as the position detection unit 700 recognizing the bottom of the transmission unit 300), the drive unit 400 stops working. At this time, the receiving unit 200 is in the initial position.

[0203] After receiving the first working signal, the drive unit 400 works, driving the transmission element 301 to move vertically from bottom to top;

[0204] While the transmission element 301 moves, the second guide element 302 moves from bottom to top along the axial direction of the first guide element 104, and the second linear sliding element 802 moves upward along the first linear sliding element 801.

[0206] The top of the transverse supporting element 201 supports the web plate (vertical steel plate) of the steel material (a combination of a vertical steel plate and a transverse steel plate) that has completed the first welding process.

[0210] The top of the transverse support element 201 does not contact the web of the steel.

[0211] Repeat the above steps until all the steel has been transferred.

[0212] The technical effects of this utility model are as follows:

[0213] 1) The first protective unit is changed from a closed structure to an open structure, which facilitates the position adjustment and maintenance of the position detection unit set at the top of the second protective unit. It does not require disassembling the entire device, reducing maintenance steps, reducing workload, and improving work efficiency.

[0214] 2) The connection between the position detection unit and the second protection unit has been changed from a fixed structure to a sliding locking structure, which makes it easier to adjust the position of the position detection unit, reduces the difficulty of adjustment, and improves the efficiency of adjustment;

[0215] 3) A linear sliding unit is added to the base unit and the receiving unit to assist the receiving unit in sliding up and down, resulting in more uniform force distribution, more stable lifting and lowering, and a reduced probability of damage to the drive unit.
