Description

Technical Field

[0002] I-beams are long strips of steel with an I-shaped cross-section. They are mainly divided into ordinary I-beams, light I-beams and wide flange I-beams. During the processing of I-beams, lifting equipment is required to lift them to other workstations. However, since the wire rope is relatively soft, during the lifting process, external factors and improper operation of the operator will cause the lifting equipment and its materials to shake and swing, posing a hidden danger to the safety of workers.

[0003] A Chinese patent with publication number "CN115838115A" discloses an I-beam lifting device, including a support frame and a fixed frame, two screw rods are symmetrically installed inside the fixed frame for rotation, motors connected to the screw rods are fixedly installed on both sides of the fixed frame, and a moving block connected by a thread is provided on the fixed frame. Through the arrangement of the fixed frame, the screw rod, the motor, the moving block and the clamping mechanism, the motor can drive the screw rod inside the fixed frame to rotate after starting, and the moving block drives the clamping mechanism to adjust its position, thereby lifting I-beams of different lengths.

[0004] During the later use, the device still had the following problems: the I-beams were mostly stacked together, and the clamping mechanism and the fixed frame were large in size. Although this ensured the stability of the hoisted I-beams, it also made it difficult for the splints to clamp the I-beams smoothly, and it was impossible to flexibly and quickly grab the I-beams, which affected work efficiency and greatly increased the labor intensity of the workers.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, an I-beam lifting equipment comprises a crane 1, which is connected to a stable hanging frame 2 through a steel cable. By setting the stable hanging frame 2, the position of the I-beam 4 can be automatically adjusted. When the center of gravity of the I-beam 4 is offset, the hook assembly 3 is driven by the adjustment assembly 7 to move horizontally in the opposite direction of the offset of the center of gravity of the I-beam 4, and the I-beam 4 is driven to return to the center position of the stable hanging frame 2, so as to keep its center of gravity in the middle of the stable hanging frame 2, so as to prevent the I-beam 4 from swinging and shaking randomly during the lifting process, which poses a threat to the safety of workers; the top of the stable hanging frame 2 is fixed A rope collecting assembly 5 is provided. By providing the rope collecting assembly 5, the power of the driving motor 501 is transmitted to the rope collecting reel 503 through the deceleration and limiting device 502, thereby pulling the rope to extend the hook assembly 3 downward to the stable hanging frame 2 or to retract the stable hanging frame 2; the rope collecting assembly 5 includes a driving motor 501 and a deceleration and limiting device 502. The deceleration and limiting device 502 can increase the torque output by the driving motor 501 and increase the upper limit of the gravity of the hook assembly 3 lifting the I-beam 4.

The rope reel 503 is connected to the hook assembly 3 through a rope. By setting the hook assembly 3, when the hook assembly 3 extends downwardly out of the stable hanging frame 2, the stable hanging frame 2 can stay in the air, allowing the hook assembly 3 to go down alone to grab the I-beam 4, thereby improving the flexibility of grabbing the I-beam 4. After the I-beam 4 is grabbed and lifted to the stable hanging frame 2, the position of the I-beam 4 can be adjusted in cooperation with the clamping plate 9, so that the center of gravity of the I-beam 4 moves to the middle of the stable hanging frame 2, thereby providing stability during the lifting process; Figure 6 , Figure 7 and Figure 8 As shown, the two ends of the top of the stable hanging frame 2 are also fixedly connected with a lifting lug 201 and a gyroscope 202. The crane 1 lifts the stable hanging frame 2 by connecting the steel cable to the lifting lug 201. After the gyroscope 202 is started, the stable hanging frame 2 can be prevented from rotating uncontrollably, which may affect the safety of the workers. The gyroscope 202 is an existing technology and can be purchased directly, so it will not be repeated here. An adjustment cavity 203 is fixedly provided in the middle of the stable hanging frame 2, and a guide inclined plate 203A is fixedly connected to the bottom of the adjustment cavity 203. The guide inclined plate 203A cooperates with the hook assembly 3. After the hook assembly 3 is lifted up, after contacting with the guide inclined plate 203A, the guide inclined plate 203A can adjust the posture of the hook assembly 3, so as to facilitate the contact and cooperation between the fixed tooth group 301A and the adjustment top tooth 703A on the hook assembly 3, and also facilitate the I-beam 4 to enter the fixed cavity 204 and contact and cooperate with the clamping plate 9; a posture sensor is installed on the stable hanging frame 2, which can sense the inclination and deflection of the stable hanging frame 2; Fig. 9 and Fig.10 As shown, an adjusting component 7 is provided in the adjusting cavity 203, and one end of the adjusting component 7 is fixedly connected to a transmission component 8. By setting the transmission component 8, when the transmission component 8 follows the adjusting component 7 to move upward, the transmission component 8 can transmit the power of the driving motor 501 to the adjusting component 7, thereby adjusting the center of gravity of the I-beam beam 4; when the transmission component 8 follows the adjusting component 7 to move downward, the transmission component 8 can transmit the power of the driving motor 501 to the rope collecting component 5, so as to adjust the hook component 3; fixed cavities 204 are fixedly provided at both ends of the stable hanging frame 2, a slide groove 204A is fixedly opened on the inner wall of the fixed cavity 204, a clamping plate 9 is slidably connected to the slide groove 204A, a slideway 205 is fixedly opened on the side wall of the inner cavity of the stable hanging frame 2, and a control component 6 is also provided on the stable hanging frame 2, and the clamping plate 9 and the adjusting component 7 are both matched with the control component 6.

[0019] like Figure 4 and Figure 5 As shown, the hook assembly 3 includes a fixed frame 301, a second lifting ear 301B is fixedly connected to the top of the fixed frame 301, and a rope reel 503 is connected to the second lifting ear 301B through a rope to suspend the fixed frame 301; a fixed tooth group 301A is fixedly connected to the outer side of the bottom of the fixed frame 301, a fixed seat 301C is fixedly connected to the center of the bottom of the fixed frame 301, a slide 302 is slidably connected to the outer wall of the fixed seat 301C, a slide groove 302A is fixedly opened on the side wall of the bottom of the slide 302, a rotating shaft 301D is fixedly connected to the bottom of the fixed seat 301C, the rotating shaft 301D is rotatably connected to the connecting rod 303, the other end of the connecting rod 303 is rotatably connected to the lifting claw 304, and the lifting claw 304 is slidably connected to the second slide groove 302A. When the lifting claws 304 contact the I-beam 4 , as the fixing frame 301 rises, the clamping force of the lifting claws 304 on the I-beam 4 gradually increases, and finally the I-beam 4 is lifted.

[0020] like Fig.15 , Fig.16 and Fig.17As shown, the adjustment assembly 7 includes a mounting slide 701, which is vertically slidably connected to the adjustment cavity 203, a limited block 701A is fixedly connected to the bottom of the mounting slide 701, a slider 702 is slidably connected to the mounting slide 701, a screw hole 702A is fixedly provided in the middle of the slider 702, a limited sliding groove 702B is fixedly provided on the outer side of the top of the slider 702, a mounting groove 702C is fixedly provided at the center of the top of the slider 702, a compression spring 704 is fixedly connected to the side wall of the mounting groove 702C, and the slider 702 The upper sliding connection is provided with a fixed claw 703, the inner side of the top of the fixed claw 703 is fixedly connected with an adjusting top tooth 703A, the adjusting top tooth 703A cooperates with the fixed tooth group 301A, the outer side of the top of the fixed claw 703 is fixedly connected with an extrusion wedge block 703B, the bottom center of the fixed claw 703 is fixedly connected with a fixed protrusion 703C, the fixed protrusion 703C is fixedly connected with a compression spring 704, the outer side of the bottom of the fixed claw 703 is fixedly connected with a limiting protrusion 703D, the limiting protrusion 703D cooperates with the limiting slide groove 702B.

[0021] When the fixing frame 301 moves upward to the inside of the adjustment chamber 203, the fixing frame 301 contacts the fixing claw 703, and the adjusting top tooth 703A clamps the fixing tooth group 301A. When the installation slide 701 rises upward, the movement of the slider 702 can drive the hook assembly 3 and the I-beam 4 to move and adjust the position of the I-beam 4. When the installation slide 701 moves downward, the adjusting top tooth 703A still clamps the fixing tooth group 301A. The movement of the slider 702 can drive the hook assembly 3 to move, but cannot adjust the position of the I-beam 4, so that the hook assembly 3 moves relative to the I-beam 4. When the installation slide 701 slides to the bottom, the adjusting top tooth 703A disengages from the fixing tooth group 301A, and the movement of the slider 702 cannot drive the hook assembly 3 and the I-beam 4. Fig.18 , Fig.19 , Fig. 20 and Fig.21 As shown, the transmission assembly 8 includes a mounting frame 801, which is fixedly connected to the mounting slide 701, and a fixed top rod 801A is fixedly connected to the rear of the mounting frame 801, and the fixed top rod 801A cooperates with the extrusion wedge 703B. When the slider 702 moves forward to the vicinity of the mounting frame 801, the fixed top rod 801A contacts the extrusion wedge 703B, so that the fixed claw 703 overcomes the elastic force of the compression spring 704 and moves to both sides, so that the fixed claw 703 is away from the fixed frame 301, and at this time, the hook assembly 3 can leave the stable hanging frame 2 under the drive of the rope collection assembly 5; the bottom of the mounting frame 801 is rotatably connected to a screw rod 802, one end of the screw rod 802 is fixedly connected to a bevel gear 803, the screw rod 802 extends backward into the mounting slide 701, and the screw rod 802 is threadedly connected to the screw hole 702A.

When the transmission assembly 8 moves downward following the installation slide 701, the driving gear 501A and the driven gear 502A are both in meshing contact with the bevel gear four 810, and the power of the driving motor 501 passes through the driving gear 501A, the bevel gear four 810, the driven gear 502A, the deceleration limit device 502 in sequence and finally reaches the rope reel 503, driving the hook assembly 3 to move; when the transmission assembly 8 moves upward following the installation slide 701, the driving gear 501A and the clutch transmission member 809 are in meshing contact, and the power of the driving motor 501 passes through the driving gear 501A, the clutch transmission member 809, the spur gear three 808, the spur gear two 807, the spur gear one 806, the transmission rod one 805, the bevel gear two 804, and the bevel gear one 803 in sequence and finally reaches the screw 802, thereby driving the movement of the slider 702.

Only when the control pull plate 603 moves to the rightmost end and the top block 605A contacts the limit block 701A, the bevel gear 3 809D will be disengaged from the driving gear 501A.

[0023] like Fig.11 and Fig.12As shown, multiple groups of limit bars 901 are fixedly connected to the inner side wall of the clamping plate 9, and the surface of the limit bars 901 is covered with rubber cover plates. When the I-beam 4 is clamped by the clamping plate 9, the side edge of the I-beam 4 can be firmly clamped by the limit bars 901, and the rubber cover plates can increase the friction between the limit bars 901 and the I-beam 4 to prevent the I-beam 4 from slipping off the clamping plate 9 and sliding down; after the clamping plate 9 clamps the I-beam 4, it only allows the I-beam 4 to move upward relative to the clamping plate 9, but prevents the I-beam 4 from moving downward relative to the clamping plate 9; a slot 902 is fixedly provided on the outer side wall of the clamping plate 9, and a fixing block 903 is fixedly connected to the slot 902.

When the fixed block 903 cooperates with the top plate 1 604A and the top plate 3 604C, the clamping plate 9 retracts into the slide slot 1 204A under the pull of the tension spring 904 and detaches from the I-beam 4. A vertical extrusion top block 605 is fixedly connected to the inner wall of the middle part of the control pull plate 603. The vertical extrusion top block 605 includes top block 1 605A, top block 2 605B, top block 3 605C and top block 4 605D. Top block 1 605A is the shortest, and top block 4 605D is the highest. When the vertical extrusion top block 605 contacts the limit block 701A, the installation slide plate 701 can be pushed upward to different heights. When the area of ​​top block one 605A is in contact with the limit block 701A, only top plate one 604A can cooperate with the clamping plate 9; when the area of ​​top block two 605B is in contact with the limit block 701A, both top plate one 604A and top plate two 604B can cooperate with the clamping plate 9, when the area of ​​top block three 605C is in contact with the limit block 701A, only top plate two 604B can cooperate with the clamping plate 9, and when the area of ​​top block four 605D is in contact with the limit block 701A, both top plate two 604B and top plate three 604C can cooperate with the clamping plate 9.

[0025] The control pull plate 603 is slidably connected to the slideway 205, the horizontal extrusion top plate 604 is matched with the fixed block 903, and the vertical extrusion top block 605 is matched with the limit block 701A.

[0026] Working principle: 1. The crane 1 lifts the stable hanging frame 2 to the top of the I-beam 4 and stops. The driving motor 501 drives the rope reel 503 to rotate and lowers the hook assembly 3. Since the hook assembly 3 is much smaller than the stable hanging frame 2, the lifting claw 304 can flexibly clamp the side edge of the I-beam 4 with the assistance of the workers; 2. The driving motor 501 drives the rope reel 503 to rotate in the opposite direction, the hook assembly 3 slowly rises, the fixing seat 301C pulls the connecting rod 303 upward, so that the lifting claw 304 clamps the I-beam 4 and lifts it, the hook assembly 3 enters the adjustment cavity 203, the fixing frame 301 pushes the fixing claw 703 upward, and the I-beam 4 enters the fixing cavity 204; 3. The electric push rod 601 retracts the push rod, slowly driving the control pull plate 603 to move to the left, and the limit block 701A changes from the original contact with the top block 1 605A to the contact with the top block 2 605B, and the top plate 2 604B contacts the fixed block 903. At this time, the clamping plate 9 clamps the side edge of the I-beam 4, and the bevel gear 3 809D meshes with the driving gear 501A. The power of the driving motor 501 can drive the screw 802 to rotate, and the fixed claw 703 lifts the fixing frame 301 upward, and drives the fixing seat 301C to move upward again. The hanging claw 304 tightly clamps the I-beam 4 to prevent it from detaching; 4. Control the pull plate 603 to continue to move to the left until the top block 605D contacts the limit block 701A, and the fixed block 903 cooperates with the top plate 604C. At this time, the clamping plate 9 releases the I-beam 4, the adjustment component 7 and the transmission component 8 are in the highest position, and the bevel gear 809D meshes with the driving gear 501A. The power of the driving motor 501 can drive the screw 802 to rotate, thereby driving the slider 702 to slide horizontally, dragging the hook component 3 and the I-beam 4, so that the center of gravity of the I-beam 4 moves to the middle of the stable hanging frame 2; 5. The electric push rod 601 extends the push rod, slowly driving the control pull plate 603 to move to the right, the top block 605D contacts the limit block 701A, and the top plate 604B contacts the fixed block 903. At this time, the clamping plate 9 clamps the I-beam 4 to prevent the I-beam 4 from falling. The I-beam 4 is in the highest position relative to the stable hanging frame 2; 6. Control the pull plate 603 to continue to move rightward, the top block 3 605C contacts the limit block 701A, and the top plate 2 604B contacts the fixed block 903. At this time, the clamping plate 9 continues to clamp the I-beam 4, and the fixed claw 703 moves downward and loses the squeeze on the fixed frame 301. Since the fixed frame 301 has no upward pulling force relative to the I-beam 4 at this time, the lifting claw 304 loses the gripping force on the I-beam 4. Driven by the adjustment component 7, the hook component 3 can move horizontally relative to the I-beam 4, and the contact point between the lifting claw 304 and the I-beam 4 is adjusted, so that the hook component 3 returns to the middle of the adjustment cavity 203, so as to prepare to adjust the center of gravity of the I-beam 4 again, thereby ensuring the stability of the I-beam 4 during the lifting process and avoiding the deflection of the stable hanging frame 2. 7. Control the pull plate 603 to continue to move rightward, so that the second top block 605B contacts the limit block 701A, and the second top plate 604B contacts the fixed block 903. At this time, the I-beam 4 continues to be clamped by the clamping plate 9, the adjustment assembly 7 and the transmission assembly 8 continue to move downward, the fixed claw 703 is separated from the fixed frame 301, and the driving motor 501 drives the screw rod 802 to move the slider 702 to the farthest end, so that the extrusion wedge block 703B contacts the fixed top rod 801A, and the fixed claw 703 opens to both sides to prevent the fixed frame 301 from being interfered by the fixed claw 703 when the hook assembly 3 is lowered; 8. Control the pull plate 603 to continue to move to the right, the top block 605A contacts the limit block 701A, and the top plate 604A contacts the fixed block 903. At this time, the I-beam 4 is separated from the clamping plate 9, and the bevel gear 4 810 is engaged with the driving gear 501A. The power of the driving motor 501 is transmitted to the rope reel 503, driving the hook assembly 3 and the I-beam 4 to be lowered, and cooperate with the workers to remove the I-beam 4 to complete the lifting of the I-beam 4.

[0027] The present invention can automatically adjust the position of the I-beam 4 by setting a stable hanging frame 2. When the center of gravity of the I-beam 4 is offset, the adjusting component 7 drives the hook component 3 to move horizontally in the opposite direction of the offset of the center of gravity of the I-beam 4, and drives the I-beam 4 back to the center position of the stable hanging frame 2, thereby keeping its center of gravity in the middle of the stable hanging frame 2, avoiding the I-beam 4 from swinging and shaking randomly during the lifting process, which poses a threat to the safety of workers; by setting the hook component 3, when the hook component 3 extends downward from the stable hanging frame 2, the stable hanging frame 2 can stay in the air, allowing the hook component 3 to go down alone to grab the I-beam 4, thereby improving the flexibility of grabbing the I-beam 4, and after the I-beam 4 is grabbed and lifted to the stable hanging frame 2, the position of the I-beam 4 can be adjusted in cooperation with the clamping plate 9, so that the center of gravity of the I-beam 4 moves to the middle of the stable hanging frame 2, providing stability during the lifting process.
