Description

Technical Field

[0001] The invention relates to the technical field of building construction lifting equipment, in particular to a windproof and shockproof lifting equipment for building construction. Background Art

[0002] In construction operations, lifting equipment plays a very important role. It can improve construction efficiency, ensure construction safety, and adapt to different construction conditions and needs. Lifting equipment includes tower cranes, construction elevators and hoists. Hoists are generally lifted by means of steel ropes and pallets. In recent years, a type of crane called spider crane has appeared. Due to its small size, it can move its position on the construction site by itself, and can enter small spaces for indoor lifting operations. It has extremely high work efficiency, so it is increasingly used in construction.

[0003] In the existing spider crane structure, the sling structure responsible for hooking the building materials needs to be released and allowed to drop vertically or be lifted vertically to achieve the purpose of lifting the building materials. However, the existing sling structures basically use steel wire ropes. The steel wire ropes have high toughness and strength, but they will inevitably swing during the descent and lifting process. Especially when the building materials are not hooked or in windy conditions, the shaking of the steel wire rope is more serious. When the spider crane is used indoors and for high-altitude operations, the shaking sling structure will undoubtedly have an adverse effect on the lifting work. For example, due to violent swinging, the building wall may be damaged, and during the lifting of building materials, the shaking of the sling may cause the material to fall.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a sling assembly that can be gathered into a rope or released into a cage, the sling structure can be windproof and anti-sway. The sling assembly adopts a composite structure. When constrained, it gathers into a rope and automatically springs open after being released to form a cage. The diameter and volume of the sling assembly after the cage is formed increase. At the same time, high-pressure air will be filled into the cage after the cage is formed. With the help of the enhanced effect of air pressure, the strength and hardness of the overall cage structure are significantly enhanced, thereby improving the stability of the sling structure, making the sling have a good windproof effect, effectively alleviating the swaying problem, and ensuring the safety of the lifting work;

[0017] 2. By setting up a leg arm reversing mechanism, and each leg arm reversing mechanism controls a leg arm respectively, the placement angle of each leg arm can be adjusted individually by using the leg arm reversing mechanism. In this way, each leg arm can be adjusted and placed in the most appropriate position according to the actual site conditions, so that the landing point of each leg arm conforms to the site conditions, thereby placing the lifting equipment reasonably and appropriately on the construction site without being restricted by site conditions. In addition, the leg arm reversing mechanism adjusts the placement angle of each leg arm, which also facilitates the rapid movement of the lifting equipment.

[0018] 3. By setting up a foot arm anti-vibration mechanism, the stability of each foot arm is improved, and each foot arm has a stabilizing effect of buffering and shockproofing. When the foot arm is folded to lift the whole machine, the foot arm anti-vibration mechanism will move synchronously, and the connected hydraulic rod will push the pressing plate downward to shrink the rubber compression airbag tube, and then the air in the rubber compression airbag tube will be pressed into the rubber folding air cylinder through the connecting pipe, forcing the rubber folding air cylinder to stretch. At this time, the foot arm will get the air cushion support of the rubber folding air cylinder, and the buffering and shockproof effect is obvious, thereby maintaining the stability of the whole machine.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure. Example

[0032] See also Figures 1 to 10 This embodiment provides a windproof and earthquake-resistant lifting equipment for construction, including:

[0033] The seat plate 1 and the track wheel 2 installed under the seat plate 1, the outer sides of the seat plate 1 are respectively installed with foot arm mounting seats 6, and the side of the foot arm mounting seat 6 away from the seat plate 1 is rotatably connected to the foot arm 7, the joint of the foot arm 7 is connected to the foot arm mounting seat 6 with a foot arm hydraulic rod 8, a foot arm reversing mechanism for independently rotating the foot arm 7 is installed between the seat plate 1 and the foot arm mounting seat 6, a foot arm anti-vibration mechanism for stabilizing the foot arm 7 is placed under the foot arm 7, the top of the seat plate 1 is fixedly connected to a gear assembly seat box 9, and the top of the gear assembly seat box 9 is fixed A support plate 22 is fixedly connected, a central control room 23 is installed on the right side above the support plate 22, and a rotating platform 24 is installed on the left side above the support plate 22. A connecting base 25 is connected above the rotating platform 24, and a boom 26 is rotatably connected above the connecting base 25. A boom hydraulic rod 27 is connected between the boom 26 and the connecting base 25. A sling storage bin 28 is fixedly provided at the left end of the boom 26, and a lifting head 30 is fixedly connected to the right end of the boom 26. The interior of the sling storage bin 28 is wound and stored with sling assemblies for lifting construction materials;

[0034] As a spider crane, the crawler wheels 2 are used to realize the movement of the crane. The foot arm 7 can be extended and folded by the hydraulic telescopic movement of the foot arm hydraulic rod 8 to lift the crane as a whole, adjust the center of gravity position, and make the chassis stable when the crane is working. The boom 26 adopts a telescopic structure, which is itself extended and retracted by hydraulic control. The pitch angle is adjusted by the hydraulic extension and contraction of the boom hydraulic rod 27, and the horizontal angle is adjusted by the rotation control function of the rotating platform 24 to complete the lifting and transportation operation of the construction materials. The sling assembly is used to hook the construction materials.

[0035] Unlike the existing spider crane, this lifting equipment is different from the existing spider crane in that the placement angle of the four legs 7 can be adjusted individually by setting a leg arm reversing mechanism, so that the four legs 7 can be placed in the most suitable position according to the actual site conditions, so that the lifting equipment can be better placed on the construction site without being restricted by the site, and the four legs 7 can adjust the angle individually, which also enables the lifting equipment to move quickly, rather than having to move through the crawler wheels 2. When used on the construction site, it is more convenient and quicker. The lifting equipment also improves the stability of the four legs 7 by setting a leg arm shockproof mechanism, thereby realizing the shockproof and stabilizing function of the four legs 7. In addition, the lifting equipment also improves the sling structure. The sling assembly adopts a composite structure, which can be gathered into a rope or released into a cage. By increasing the diameter width of the sling structure, expanding the volume of the sling structure, and improving the stability of the sling structure, the sling has a good windproof effect, effectively alleviating the shaking problem, thereby ensuring the safe progress of the lifting work. Example

[0036] The sling assembly includes a central sling 32 located at the center of the sling assembly, and a connecting sleeve 33 is fixedly connected to the outer side of the rope body of the central sling 32 at equal distances. An outward-expanding sling segment 34 is evenly connected in a ring shape between two adjacent connecting sleeves 33. The inner side of the outward-expanding sling segment 34 and the outer side surface of the central sling 32 are connected with a supporting sling segment 35. The outermost sides of the two adjacent outward-expanding sling segments 34 are connected in series with a reinforcing sling segment 36. The bottom of the bottom outward-expanding sling segment 34 is connected to a connecting sling segment 37. The bottom of the central sling 32 is connected to an air distribution base 40, and the bottom of the air distribution base 40 and the bottom of the connecting sling segment 37 are jointly connected to a sling connecting plate 42. A high-pressure air pump 44 is installed below the sling connecting plate 42, and a hook 45 is provided below the high-pressure air pump 44. The sling assembly also includes the following parts which are respectively passed through the central sling 32, the outward-expanding sling segment 34, the supporting sling segment 35, and the outer side surface of the central sling 32. The rubber sealing sheaths 38 on the inner sides of the rope section 35, the reinforcement rope section 36 and the connecting rope section 37 are all provided with memory core strips 39 in the inner centers of the rubber sealing sheaths 38. The rubber sealing sheaths 38 are all connected to each other, and the rubber sealing sheaths 38 are respectively tightly attached to the central rope 32, the outward-expanding rope section 34, the supporting rope section 35, the reinforcement rope section 36 and the connecting rope section 37. The lower outer wall of the air distribution base 40 is connected with an air distribution pipe 41 at equal angles, and the ends of the air distribution pipe 41 are respectively connected to the bottom end of the connecting rope section 37. The air distribution pipe 41 is connected to the rubber sealing sheath 38 located inside the connecting rope section 37. An air inlet pipe 43 is provided through the center of the lower surface of the sling connecting plate 42. The upper end of the air inlet pipe 43 is connected to the bottom of the air distribution base 40, and the lower end of the air inlet pipe 43 is connected to the air outlet of the high-pressure air pump 44 through a hose.

[0037] The sling assembly adopts a composite structure. When the sling assembly automatically pops open, it can form a cage-like structure, thereby expanding the radial area of the sling structure, increasing the volume of the sling structure, and strengthening the overall strength of the sling structure, thereby alleviating the shaking problem. The supporting rope segment 35 is used to support the outward-expanding rope segment 34, ensuring that the outward-expanding rope segment 34 can be fully expanded and maintain structural strength. The reinforcing rope segment 36 causes the outward-expanding rope segments 34 to have a pulling effect on each other, and is used to reinforce the outward-expanding rope segment 34 to prevent axial deflection.

[0038] The inner sides of the central sling 32, the outward-expanding sling section 34, the supporting sling section 35, the reinforcing sling section 36 and the connecting sling section 37 are all connected and communicated with each other through a rubber sealing sheath 38, and a sealed and closed environment is formed. The rubber sealing sheath 38 can be filled with high-pressure gas. The increase in the air pressure in the rubber sealing sheath 38 enhances the strength and hardness of the rubber sealing sheath 38, thereby improving the strength and hardness of the entire sling assembly. After the sling assembly automatically springs open, it can become hard under the influence of the high-pressure airflow and will not bend, thereby maintaining high strength and hardness. The sling assembly is transformed from a rope into a cage, and the strength is further improved after high-pressure inflation, which can effectively avoid the shaking problem during high-altitude operation and make lifting safer and more reliable.

[0039] The high-pressure air pump 44 is connected to the air inlet pipe 43 through a hose, and inputs the high-pressure air flow into the air distribution base 40. The high-pressure air flow is then dispersed into the rubber sealing sheaths 38 in each connecting sling rope segment 37 through the air distribution pipe 41, and then upwardly fills the sling assembly along the rubber sealing sheath 38, and inflates the released sling assembly with high pressure to enhance the strength and hardness of the sling assembly. When the sling assembly is reeled after hooking the building material, the high-pressure air pump 44 simultaneously performs an exhaust operation to re-extract the high-pressure air originally filled in the sling assembly, so that the sling assembly can restore its original flexibility so that it can be gathered into a rope and well wound and stored;

[0040] The memory core strip 39 is made of memory material and is used to gather and unfold the sling assembly so that the sling assembly can achieve structural switching from a rope to a cage. Example

[0041] The foot arm reversing mechanism includes a connecting block 4 that is slidably installed between the seat plate 1 and the support plate 22 and around the outer side of the gear assembly seat box 9. The foot arm mounting seat 6 is fixedly connected to the side of the connecting block 4 away from the gear assembly seat box 9. The four corner box walls of the gear assembly seat box 9 are all provided with slots 10, and the inner sides of the slots 10 are exposed with reversing gears 11. The reversing gears 11 are respectively arranged at the four inner corners of the gear assembly seat box 9, and the bottom shaft ends of the reversing gears 11 are connected to the rotary control motors 12. The inner side surfaces of the connecting blocks 4 are provided with serrated structures that mesh with the reversing gears 11. The upper surface edge of the seat plate 1 and the lower surface edge of the support plate 22 are both provided with slide grooves 3, and the upper and lower surfaces of the connecting block 4 are respectively fixed with slide bars 5 that slide with the slide grooves 3.

[0042] In the foot arm reversing mechanism, the rotary control motor 12 is connected to and controls the reversing gear 11, driving the reversing gear 11 to rotate. After the reversing gear 11 rotates, the meshing action between the saw teeth drives the connecting block 4 to move. The connecting block 4 moves stably between the seat plate 1 and the support plate 22 with the sliding cooperation between the slide bar 5 and the slide groove 3. As the connecting block 4 moves, the foot arm mounting seat 6 moves accordingly, thereby driving the foot arm 7 to rotate the angle, thereby achieving the purpose of adjusting the placement angle of the foot arm 7. The four foot arms 7 are each controlled by a foot arm reversing mechanism and can be adjusted separately. At the same angle, the support point position of the lifting equipment is reasonably adjusted to adapt to the site, so that the lifting equipment can be stably and effectively supported. At the same time, when the position of the lifting equipment needs to be adjusted, there is no need to fold up the four legs 7, lower the track wheels 2 to the ground, and move the equipment through the movement of the track wheels 2. Instead, the leg reversing mechanism can be used to adjust the direction of the leg 7, and the leg hydraulic rod 8 can be used to control the hydraulic extension and contraction of the leg 7 to move the position of the entire lifting equipment. It is more suitable for construction sites and the position movement is fast and convenient. Example

[0043] The foot arm anti-vibration mechanism includes a through slot 13 which is provided on the side wall of the lower arm portion of the foot arm 7. The lower arm portion of the foot arm 7 is a hollow structure, and a rubber compression airbag tube 14 is fixedly provided at the bottom of the lower arm portion of the foot arm 7. A pressing plate 15 is sealed and fixed to the top of the rubber compression airbag tube 14. The upper surface of the pressing plate 15 is rotatably connected to a connecting hydraulic rod 16. The other end of the connecting hydraulic rod 16 is rotatably connected to the lower surface of the upper arm portion of the foot arm 7. The foot arm anti-vibration mechanism also includes a hinged portion on the foot arm. A ground connection plate 17 at the bottom end of the lower arm portion has a foldable rubber air cylinder 18 fixedly connected to the lower middle portion of the ground connection plate 17, and a ground contact plate 19 fixedly connected to the bottom end of the foldable rubber air cylinder 18. A limiting guide rod 20 is fixedly connected to the upper edge of the ground contact plate 19, and the top end of the limiting guide rod 20 passes through the inner edge of the ground connection plate 17. A connecting pipe 21 is connected to the upper surface of the ground connection plate 17, and the connecting pipe 21 connects the rubber compression air bag tube 14 and the foldable rubber air cylinder 18.

[0044] The anti-vibration mechanism of the foot arm is set under the foot arm 7. After the foot arm 7 is opened, the connecting hydraulic rod 16 is hydraulically extended to a fixed length (and when the foot arm 7 is fully retracted, the connecting hydraulic rod 16 will start again and retract to a length that allows the foot arm 7 to be normally folded). In order to lift the entire lifting equipment, the foot arm 7 will be folded, and the connecting hydraulic rod 16 will be pulled, and the end connected to the pressing plate 15 will gradually move downward. The pressing plate 15 will then move downward inside the lower arm part of the foot arm 7, thereby pressing the rubber compression airbag tube 14, so that the rubber compression airbag tube 14 The compression air bag 14 contracts, and the air in the rubber compression air bag 14 will be squeezed out into the rubber folding air cylinder 18 through the connecting tube 21, so that the rubber folding air cylinder 18 stretches out, and the rubber folding air cylinder 18 is filled with air, and the height is increased. The filled air also makes the rubber folding air cylinder 18 have a good buffering and vibration isolation effect. This is equivalent to adding an air cushion at the bottom of the leg arm 7, so that the leg arm 7 touches the ground stably while obtaining the protection effect of buffering and vibration isolation, thereby improving the stability of the entire lifting equipment. Example

[0045] A sling pulling roller 29 is rotatably mounted below the boom 26 near the sling storage bin 28, and a telescopic protective tube 31 is provided on the right side of the sling pulling roller 29. The fixed end of the telescopic protective tube 31 is fixedly connected to the bottom of the boom 26, and the movable end of the telescopic protective tube 31 is configured to be a circular arc structure bent vertically downward. The movable end of the telescopic protective tube 31 passes through the lower interior of the lifting head 30, and the movable end of the telescopic protective tube 31 is fixedly connected to the lifting head 30. The movable end port of the telescopic protective tube 31 is configured to be open, and the sling assembly passes through the interior of the telescopic protective tube 31.

[0046] The sling pulling roller 29 can rotate flexibly and is used to support and straighten the sling assembly so that the sling assembly can be well wound and released. The telescopic protective tube 31 adopts a telescopic structure and can be telescoped and extended following the telescopic movement of the boom 26. The sling assembly passes through the telescopic protective tube 31. Restricted by the telescopic protective tube 31, the sling assembly will not automatically bounce open. It will only be released into a cage after coming out of the port of the telescopic protective tube 31. This can ensure that the sling assembly has a good traction transition and also ensure that the structure of the boom 26 is neat.

[0047] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
