Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, specifically relating to a non-disassembly support anti-collision rotating lifting device and lifting equipment. Background Technology

[0002] In subway construction, gantry cranes are mainly used for slag removal, segment installation, and material transportation. They achieve efficient slag removal through hydraulic tilting mechanisms, and transport precast segments and construction materials. They work in conjunction with tunnel boring machines and other equipment to form a production line.

[0003] Steel supports are a core component of deep foundation pit support systems, primarily used to balance soil pressure on the outer side of the retaining structure and prevent foundation pit collapse. However, the installation of steel supports also impacts crane lifting operations. Due to the obstruction effect of the steel supports on the lifting equipment, cranes often cannot lift materials to the area beneath the steel supports. In such cases, the materials must be lifted to a designated location within the foundation pit and then transferred using internal transport equipment. This method is labor-intensive, time-consuming, and inefficient.

[0004] Temporarily removing steel supports is also a common method, but it must meet certain technical conditions, follow legal procedures, and take strict safety measures.

[0005] Therefore, it is necessary to design a non-dismantling, anti-collision rotating lifting device and hoisting equipment that can hoist materials to the area below the steel support, saving labor and improving hoisting efficiency to solve the current technical problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a non-dismantling, anti-collision rotating lifting device and hoisting equipment that can hoist materials to the area below the steel support, saving labor and improving hoisting efficiency.

[0007] The technical solution of the present invention is as follows: a non-disassembly support anti-collision rotating hanger, including a connecting plate, a pulley assembly rotatably arranged above the connecting plate, a rotation adjustment mechanism for driving the pulley assembly to rotate relative to the connecting plate, two C-shaped frames symmetrically arranged at the bottom of the connecting plate, a hanger arranged below the C-shaped frames, and two sets of lifting adjustment mechanisms symmetrically arranged at the top of the hanger. The top end of the lifting adjustment mechanism is hinged to the bottom of the C-shaped frame, and the bottom end of the lifting adjustment mechanism is hinged to the top of the hanger.

[0008] Furthermore, the rotation adjustment mechanism has a pivot centrally and vertically fixed at the bottom of the pulley assembly, a support plate fixedly mounted at the bottom end of the pivot, a slewing bearing concentrically mounted at the bottom of the connecting plate and the pivot, the support plate being rotatably connected to the connecting plate via the slewing bearing, a driven gear fixedly mounted on the pivot, a driving gear rotatably mounted on the connecting plate and meshing with the driven gear, and an angle adjustment motor for driving the driving gear to rotate being mounted at the bottom of the connecting plate.

[0009] Furthermore, the angle adjustment motor is a servo geared motor.

[0010] Furthermore, the lifting and adjusting mechanism has two upper booms respectively hinged to the bottom of the two C-shaped frames. A lower boom is hinged to one end of the upper boom away from the C-shaped frame, and the other end of the lower boom away from the upper boom is hinged to the top of the frame. An upper support shaft is provided between the two upper booms, and a lower support shaft is provided between the two lower booms. A lifting hydraulic cylinder is provided between the upper support shaft and the lower support shaft.

[0011] Furthermore, the C-shaped frame has connecting columns, with parallel horizontal beams at both ends of the connecting columns, and a collision detection mechanism is provided on the outer side of the connecting columns.

[0012] Furthermore, the collision detection mechanism has a buffer airbag, on which a barometer is installed and communicates with its interior. The barometer is electrically connected to a wireless data transmission module, and the wireless data transmission module is electrically connected to a power supply module for supplying power to the barometer and itself. One side of the buffer airbag is fixedly mounted on the connecting column.

[0013] Furthermore, the C-shaped frame is equipped with through-beam gratings; when the optical path between the through-beam gratings is blocked, the lifting equipment cannot control the lifting and lowering of the lifting device.

[0014] Furthermore, the through-beam grating has a grating transmitter and a grating receiver; the two horizontal beams in the C-shaped frame are respectively provided with corresponding grating transmitters and grating receivers on opposite sides.

[0015] Furthermore, the pulley assembly has a rope wheel support plate, and two shaft seats are symmetrically arranged on the top of the rope wheel support plate, with a rope wheel rotatably arranged inside the shaft seats.

[0016] Lifting equipment, including the non-disassembly support anti-collision rotating lifting device and lifting equipment as described in any of the preceding items.

[0017] The beneficial effects of this invention are:

[0018] (1) In this invention, the pulley assembly is connected to the wire rope of the lifting equipment. The lifting device of the lifting equipment rewinds and releases the wire rope to realize the lifting or lowering of the lifting device. The lifting equipment is preset to stop when the lifting device lowers the lifting device to a position where the center of the C-shaped frame in the vertical direction is parallel to the axis of the steel support. At this time, the connecting plate is driven to rotate 90° by the rotation adjustment mechanism, so that the opening end of the C-shaped frame corresponds to the steel support and then moves horizontally. The opening area inside the C-shaped frame avoids the steel support, and the material can be hoisted to the area below the steel support without removing the steel support, avoiding secondary transfer of materials, saving labor and improving hoisting efficiency.

[0019] (2) In order to facilitate the stable placement of materials of different heights on the ground by the lifting frame, a lifting adjustment mechanism is set between the lifting frame and the C-shaped frame. After the lifting device is moved into place, the lifting adjustment mechanism drives the lifting frame to move down stably until the material contacts the ground and is placed stably on the ground.

[0026] Various exemplary embodiments of the invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the invention or its application or use. The invention can be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the invention thorough and complete, and to fully express the scope of the invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, without excluding the possibility of encompassing other elements. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] like Figures 1 to 5 As shown, a non-disassembly support anti-collision rotating lifting device includes a connecting plate 8, a pulley assembly 2 rotatably mounted on the top of the connecting plate 8, a rotation adjustment mechanism 3 on the connecting plate 8 that drives it to rotate relative to the pulley assembly 2, two C-shaped frames 1 symmetrically mounted on the bottom of the connecting plate 8, a hanging frame 7 mounted below the C-shaped frames 1, and two sets of lifting adjustment mechanisms 6 symmetrically mounted on the top of the hanging frame 7. The top end of the lifting adjustment mechanism 6 is hinged to the bottom of the C-shaped frame 1, and the bottom end of the lifting adjustment mechanism 6 is hinged to the top of the hanging frame 7.

[0029] In the above embodiment, the pulley assembly 2 is connected to the wire rope of the lifting equipment. The lifting device of the lifting equipment rewinds and releases the wire rope to raise or lower the lifting device. The lifting equipment is preset to stop when the lifting device lowers the lifting device to a position where the center of the C-shaped frame 1 in the vertical direction is aligned with the axis of the steel support. At this time, the connecting plate 8 is rotated 90° by the rotation adjustment mechanism 3, so that the open end of the C-shaped frame 1 corresponds to the steel support and then moves horizontally. The opening area inside the C-shaped frame 1 avoids the steel support, and the material can be lifted to the area below the steel support without removing the steel support, avoiding secondary transfer of materials, saving labor, and improving lifting efficiency. In order to facilitate the stable placement of materials of different heights on the ground by the lifting frame 7, a lifting adjustment mechanism 6 is set between the lifting frame 7 and the C-shaped frame 1. After the lifting device moves into position, the lifting adjustment mechanism 6 drives the lifting frame 7 to move down steadily until the material contacts the ground and is placed stably on the ground.

[0030] In some embodiments, as a specific implementation of the rotation adjustment mechanism 3 in the above embodiments, such as Figure 3 and 5As shown, the rotation adjustment mechanism 3 has a pivot 31 centrally and vertically fixed at the bottom of the pulley assembly 2. A support plate 32 is fixedly installed at the bottom end of the pivot 31. A slewing bearing 33 is concentrically installed at the bottom of the connecting plate 8 with the pivot 31. The support plate 32 is rotatably connected to the connecting plate 8 through the slewing bearing 33. A driven gear 35 is fixedly mounted on the pivot 31. A driving gear 36 that meshes with the driven gear 35 is rotatably installed on the connecting plate 8. An angle adjustment motor 34 that drives the driving gear 36 to rotate is installed at the bottom of the connecting plate 8. The angle adjustment motor 34 drives the driving gear 36 to rotate. The driving gear 36 meshes with the driven gear 35, driving the connecting plate 8 to rotate relative to the pivot 31, thereby realizing the angle adjustment of the lifting device.

[0031] In some embodiments, the angle adjustment motor 34 is a servo geared motor, which not only has high angle control accuracy but also can output large torque.

[0032] In some embodiments, as a specific implementation of the lifting adjustment mechanism 6 in the above embodiments, such as Figure 1 and 2 As shown, the lifting adjustment mechanism 6 has two upper booms 61 respectively hinged to the bottom of the two C-shaped frames 1. A lower boom 62 is hinged to one end of the upper boom 61 away from the C-shaped frame 1, and the other end of the lower boom 62 away from the upper boom 61 is hinged to the top of the lifting frame 7. An upper support shaft 63 is provided between the two upper booms 61, and a lower support shaft 64 is provided between the two lower booms 62. A lifting hydraulic cylinder 65 is provided between the upper support shaft 63 and the lower support shaft 64. When the lifting device moves into position, the lifting hydraulic cylinders 65 in the two lifting adjustment mechanisms 6 are synchronously extended. The lifting hydraulic cylinders 65 drive the lower support shaft 64 to move the lower boom 62 downward, thereby causing the lifting frame 7 to move the lifted material downward until the lifted material is stably placed on the ground, and then the lifting hydraulic cylinders 65 are controlled to stop moving.

[0033] In some embodiments, such as Figure 4 As shown, the C-shaped frame 1 has a connecting column 12, and parallel horizontal beams 11 are provided at both ends of the connecting column 12. A collision detection mechanism 4 is provided on the outside of the connecting column 12. During the rotation, if a collision occurs between the connecting column 12 and the steel support, the collision detection mechanism 4 can identify it in time and stop the lifting device from continuing to rotate.

[0034] In some embodiments, as a specific implementation of the collision detection mechanism 4 in the above embodiments, such as Figure 6As shown, the collision detection mechanism 4 has a buffer airbag 41, on which a barometer 42 is installed and connected to its interior. A wireless data transmission module 43 is electrically connected to the barometer 42, and a power supply module 44 is electrically connected to the wireless data transmission module 43 to supply power to the barometer 42 and the barometer 42. One side of the buffer airbag 41 is fixedly mounted on the connecting column 12. The buffer airbag 41 acts as a buffer during a collision, preventing direct contact between the C-shaped frame 1 and the steel support. During a collision, the buffer airbag 41 is compressed, reducing the volume of air inside. According to Boyle's Law, the pressure rises. The barometer detects the pressure change through a sensor and converts it into an electrical signal, which is output to the wireless data transmission module 43. The wireless data transmission module 43 has a preset pressure threshold. A wireless receiving module connected to the crane controller communicates wirelessly with the wireless data transmission module 43. When the pressure change exceeds the pressure threshold, the wireless data transmission module 43 sends a warning signal to the crane controller. Upon receiving the warning signal, the crane controller immediately stops the angle adjustment motor 34.

[0035] In some embodiments, a through-beam grating 5 is provided on the C-shaped frame 1; when the light path between the through-beam gratings 5 ​​is blocked, the lifting equipment cannot control the lifting of the spreader; the through-beam grating 5 is connected to the controller of the crane, and when the steel support enters the clearance space inside the C-shaped frame 1, the steel support blocks the light path between the through-beam gratings 5, at which time the lifting control circuit of the crane is disconnected to avoid accidental lifting of the spreader, which would cause a collision between the horizontal beam and the steel support.

[0036] In some embodiments, the through-beam grating 5 has a grating transmitter 51 and a grating receiver 52; the two horizontal beams 11 in the C-shaped frame 1 are respectively provided with corresponding grating transmitters 51 and grating receivers 52 on opposite sides.

[0037] In some embodiments, such as Figure 5 As shown, the pulley assembly 2 has a rope wheel support plate 21. Two shaft seats 22 are symmetrically arranged on the top of the rope wheel support plate 21. A rope wheel 23 is rotatably arranged inside the shaft seat 22. The rope wheel 23 is connected to the wire rope on the trolley of the lifting equipment.

[0038] In some embodiments, a lifting device is disclosed, including a non-disassembly support anti-collision rotating hoist and lifting device as described in any of the preceding embodiments.

Those skilled in the art will fully understand how to implement the technical solutions disclosed herein based on the above description.

[0040] The embodiments described above only illustrate some implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
