Description

Technical Field

[0001] This utility model belongs to the field of safety protection technology for lifting machinery, specifically, it relates to a high-efficiency and high-performance electric windproof iron wedge for gantry cranes. Background Technology

[0002] Modular integrated building factories are equipped with a large number of bridge cranes and gantry cranes, which play a crucial role in the production, finishing, and transportation of precast concrete components. Due to the fast pace and heavy workload within the factory, and the large volume of overall project transportation, day and night shifts are often required to meet production demands. Furthermore, the outdoor storage yards for finished products are frequently exposed to severe weather conditions such as wind, rain, and snow, which can easily cause building materials to fall onto the gantry crane tracks, increasing operational risks.

[0003] Currently, locking gantry cranes on the rails mainly relies on manual rail clamps or ordinary windproof iron wedges. These traditional devices work by physically fixing the crane to the rails to prevent it from moving due to wind or other external forces. However, this method has significant shortcomings in the following aspects.

[0004] Low operational efficiency: Traditional devices require manual opening and closing each time they are used, which not only increases labor costs but also reduces the efficiency of transportation.

[0005] Equipment damage: Outdoor environments can easily cause mechanical parts of traditional equipment to rust and jam, or electrical components to fail or become misaligned. In addition, during use, wear and tear can easily occur on the end beam wheels or other equipment bodies, shortening the service life of the equipment.

[0006] Safety hazards: Due to the high failure rate of traditional equipment, it is insufficient to support the fast-paced, high-quality production, transfer and transportation of precast concrete components, and may cause the gantry crane to slip, derail or even overturn, seriously threatening the safety of people's lives and property.

[0007] In summary, existing gantry crane locking devices have significant shortcomings in terms of operational efficiency, safety, and equipment protection, and there is an urgent need for a highly efficient and high-performance alternative. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] This embodiment provides a high-efficiency, high-performance electric windproof wedge for gantry cranes, which is fixedly connected to the end beam 2 of the gantry crane and moves along the track 1 with the gantry crane. When necessary, it is used to lock the traveling wheels 3 of the gantry crane.

[0035] Specifically, such as Figures 1-5As shown, the assembly includes a support component 4, a connecting plate component 5, a connecting frame 6, a pusher component 7, a linkage mechanism component 8, a windproof wedge 9, a steel wire 10, and a track clamp 11. The support component 4 is fixedly installed on the end beam 2. The connecting plate component 5 is fixedly connected to one side of the support component 4. The connecting frame 6 is fixedly installed at both ends of the connecting plate component 5. The pusher component 7 and the linkage mechanism component 8 are fixed between the two connecting frames 6. The top of the pusher component 7 is connected to the linkage mechanism component 8. The windproof wedge 9 is connected to one end of the linkage mechanism component 8. The windproof wedge 9 is provided with a wedge rubber 18 and has a serrated bottom. There are two steel wires 10. One end of the steel wire 10 is connected to the top of the pusher component 7, and the other end of the steel wire 10 is connected to the track clamp 11. The track clamp 11 is scissor-type and is provided with a spring 12. The support assembly 4 and connecting plate assembly 5 are responsible for fixing the entire device to the end beam 2 of the gantry crane; the connecting frame 6 is used to support and fix components such as the pusher assembly 7 and the linkage mechanism assembly 8; the pusher assembly 7 is responsible for providing power, and the windproof wedge 9 is raised and lowered through the linkage mechanism assembly 8; the windproof wedge 9 is used to fit tightly with the traveling wheels 3 when the gantry crane stops working, preventing the crane from moving due to wind or other external forces. The serrated structure can increase the friction with the rail 1, while the wedge rubber 18 can provide better fit and The wear resistance allows it to be adapted to various sizes of traveling wheels 3, which not only improves flexibility and service life, but also significantly reduces the wear of the traveling wheels 3; the steel wire 10 plays a connecting and transmission role. When the pusher assembly 7 is working, the steel wire 10 will tighten or loosen accordingly, thereby driving the rail clamp 11 to open or close, realizing the locking or unlocking function of the gantry crane; the spring 12 on the rail clamp 11 mainly provides the restoring force, maintains the clamping force, and realizes buffering and shock absorption, reducing the direct impact between the rail clamp 11 and the rail 1, and protecting the rail clamp 11 and the rail 1 from damage.

[0036] The pusher assembly 7 lifts the windproof wedge 9 upward through the linkage mechanism assembly 8, separating it from the traveling wheel 3 of the gantry crane. At the same time, the high-strength connecting steel wire 10 causes the scissor-type rail clamp 11 to loosen outward and release the lock. Conversely, when the pusher assembly 7 is de-energized, the windproof wedge 9 falls and fits tightly against the traveling wheel 3. The rail clamp 11 falls and, under the adjustment of the spring 12, is firmly clamped on the running rail 1, completing the stable locking of the gantry crane.

[0037] Specifically, such as Figure 1As shown, the support assembly 4 includes a support panel 41 and two support stiffeners 42. The support panel 41 is welded to the end beam 2. One side of the support stiffener 42 is welded to the support panel 41, and the bottom is welded to the end beam 2. The support stiffeners 42 are used to enhance the strength and stability of the support panel 41 and prevent deformation or damage caused by external forces or vibrations. The connecting plate assembly 5 includes an inner connecting plate 51, an outer connecting plate 52, and waist-hole bolts 53. The inner connecting plate 51 is welded to the connecting frame 6, and the outer connecting plate 52 is welded to the support panel 41. The inner connecting plate 51 and the outer connecting plate 52 are connected by multiple waist-hole bolts 53. By adjusting the position of the waist-hole bolts 53, the height of the end beam 2 of various gantry cranes can be adapted to ensure the versatility and adaptability of the device.

[0038] Specifically, such as Figure 2 As shown, the linkage mechanism assembly 8 includes an iron wedge connecting plate 81, a first pin 82, a fixing plate 83, a fixing shaft 84, and a second pin 85. The fixing shaft 84 and the first pin 82 are fixedly installed between two connecting frames 6. One end of the fixing plate 83 is sleeved on the fixing shaft 84, and the other end of the fixing plate 83 is sleeved on the first pin 82. One end of the iron wedge connecting plate 81 is sleeved on both ends of the first pin 82, and the other end of the iron wedge connecting plate 81 is sleeved on both ends of the second pin 85. A windproof iron wedge 9 is installed on the second pin 85. Plate 81 is used to install and fix the windproof iron wedge 9, ensuring that the windproof iron wedge 9 can be raised or lowered with the movement of the linkage mechanism; pin 82 is used to connect the fixing plate 83 and the iron wedge connecting plate 81, as well as the pusher rod end 73, to realize the rotation and fixation of the linkage mechanism; fixing shaft 84 and fixing plate 83 are used to ensure the stability and reliability of the linkage mechanism; fixing shaft 84 provides the axis of rotation of the linkage mechanism; pin 85 is used to ensure that the windproof iron wedge 9 can be raised or lowered with the movement of the linkage mechanism.

[0039] Specifically, such as Figure 2 and Figure 3 As shown, the actuator assembly 7 includes a hydraulic actuator 71, an actuator shaft 72, and an actuator frame 74. The actuator shaft 72 is fixedly connected to the bottom of two connecting frames 6. The hydraulic actuator 71 is fixedly mounted on the actuator shaft 72. The top of the hydraulic actuator 71 is provided with an actuator rod end 73. The actuator rod end 73 is sleeved on the pin 82. The actuator frame 74 is fixedly mounted on the actuator rod end 73. Two steel wires 10 are connected to both ends of the actuator frame 74.

[0040] To allow for flexible position adjustment of the windproof wedge 9 during lifting and lowering, increasing its stability and adapting to various working conditions, such as... Figure 5As shown, it also includes an adaptive component 17, which is located on one side of the windproof wedge 9. The adaptive component 17 includes a tightening bolt 171, a second spring 172, and a fixing member 173. The fixing member 173 is set at the end of the wedge connecting plate 81 near the second pin 85. The tightening bolt 171 is fixed on the fixing member 173. The second spring 172 is sleeved on the tightening bolt 171. The second spring 172 can provide the elastic force or restoring force of the adaptive component 17. When the windproof wedge 9 is raised or lowered, the second spring 172 will be compressed or extended accordingly, thereby ensuring that the adaptive component 17 can flexibly adjust its position and maintain the stability of the windproof wedge 9.

[0041] To prevent rainwater from causing mechanical structure damage, rust, jamming, and electrical component failure or misalignment, such as... Figure 1 As shown, it also includes a rain cover 16, which is tilted on both sides and fixedly installed on the top of the support panel 41 to ensure that it can effectively block rainwater without affecting the normal operation and maintenance of the device.

[0042] To improve equipment and personal safety, such as Figure 1 As shown, the system also includes a photoelectric limit assembly 15 and an anti-collision rubber assembly 13. The photoelectric limit assembly 15 includes a photoelectric limiter and a photoelectric limit frame, wherein the photoelectric limit frame is fixedly installed on the inner connecting plate 51, and the photoelectric limiter is installed on the photoelectric limit frame. The anti-collision rubber assembly 13 includes an anti-collision rubber 131 and an anti-collision rubber base plate 132. The anti-collision rubber base plate 132 is fixedly installed on the side of the two connecting frames 6 away from the end beam 2, and the anti-collision rubber 131 is disposed on the outer surface of the anti-collision rubber base plate 132. The photoelectric limit assembly 15 is used to limit the operating range of the gantry crane and prevent it from exceeding the predetermined track 1 range. When the gantry crane approaches the end of the track 1, the photoelectric limiter will sense it and send a signal to stop the crane, thereby avoiding accidents such as collisions or derailments. The anti-collision rubber assembly 13 is used to prevent the equipment from colliding with people or objects during operation, improving the safety factor of the equipment and personnel. When the equipment collides, the anti-collision rubber 131 can absorb part of the impact force, reducing the damage to the equipment and personnel.

[0043] To prevent other debris left on track 1 from damaging the equipment or even causing the gantry crane to derail and overturn, such as Figure 1 As shown, it also includes a track cleaner 14, which is installed on the side of the two connecting frames 6 away from the end beam 2, with its bottom close to the surface of the track 1.

[0044] The working principle of this utility model is as follows.

[0045] The electric windproof iron wedge 9 is electrically interlocked with the anemometer, PLC, and frequency converter of the gantry crane. When the wind speed reaches level six, the device can automatically lock, achieving high-efficiency and safer production transfer and transportation.

[0046] Specifically, the electric windproof wedge 9 is connected to the electrical safety circuit of the gantry crane. When the operator controls the trolley to move via remote control, the hydraulic pusher 71 is energized, and the pusher rod end 73 moves upward. Through the linkage mechanism, the windproof wedge 9 is lifted upward. The first pin shaft 82 rises with the pusher rod end 73, and the fixed plate 83 rotates around the first pin shaft 82 and at the same time around the fixed shaft 84. The wedge connecting plate 81 and the fixed plate 83 move closer to each other. The wedge connecting plate 81 rises with the first pin shaft 82 and at the same time rotates around the first pin shaft 82, driving the second pin shaft 85 and the windproof wedge 9 upward and separating from the gantry crane traveling wheel 3. When the pusher rod end 73 moves upward, the connecting frames 6 at both ends and the high-strength steel wire 10 drive the rail clamp 11 to loosen the rail 1 outward, so that the gantry crane trolley can move normally.

[0047] When the operator stops operating the remote control, after a delay of several seconds by the timer system, the hydraulic actuator 71 loses power and stops operating. The actuator rod end 73 drives the linkage mechanism to slowly fall down, the windproof iron wedge 9 and the gantry crane traveling wheel 3 fit tightly together, the rail clamp 11 falls down and is steadily clamped on the running rail 1 under the adjustment of the spring, so that the gantry crane is stably locked on the rail 1.

[0048] The track clamp 11 is equipped with a mechanical limit switch near the bottom, which can detect abnormal states such as opening when the track clamp 11 is not operating normally. When the state is abnormal, an alarm signal is generated to automatically cut off the power supply of the equipment and feedback is given to the operator.

[0049] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
