The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention. Example

[0020] See also Figures 1 to 10 This embodiment provides a windproof and earthquake-proof lifting equipment for construction, including: 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 with a foot arm 7, a foot arm hydraulic rod 8 is connected between the joint of the foot arm 7 and the foot arm mounting seat 6, 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 arranged below the foot arm 7, a gear assembly seat box 9 is fixedly connected above the seat plate 1, and the gear assembly seat box 9 is fixed above 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, and a sling assembly for lifting building materials is wound and stored inside the sling storage bin 28; As a spider crane, the crawler wheel 2 is 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 and adjust the center of gravity to make the chassis stable when the crane is working. The boom 26 adopts a telescopic structure, which is hydraulically controlled to achieve telescopic movement. The pitch angle is adjusted by the hydraulic telescopic movement of the boom hydraulic rod 27, and the angle is adjusted horizontally by the rotation control function of the rotating table 24, so as to complete the lifting and transportation operation of the building materials. The sling assembly is used to hook the building materials. Unlike the existing spider crane, this lifting equipment can individually adjust the placement angles of the four arms 7 by setting up an arm reversing mechanism, so that the four arms 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 arms 7 can adjust their angles individually, which also enables the lifting equipment to move quickly instead of having to use the crawler wheels 2 to move the position. When used on the construction site, it is more convenient and quicker. The lifting equipment also improves the stability of the four arms 7 by setting up an arm anti-vibration mechanism, thereby realizing the anti-vibration and stabilization function of the four arms 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 safety of the lifting work. Example

[0021] The sling assembly includes a central sling 32 located at the center of the sling assembly, 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 to two adjacent connecting sleeves 33 in a ring shape, a supporting sling segment 35 is connected to the inner side of the outward-expanding sling segment 34 and to the outer side of the central sling 32, a reinforcing sling segment 36 is connected in series to the outermost sides of the two upper and lower adjacent outward-expanding sling segments 34, a connecting sling segment 37 is connected below the bottom of the outward-expanding sling segment 34, an air distributor base 40 is connected to the bottom of the central sling 32, and a sling connecting plate 42 is commonly connected to the bottom of the air distributor base 40 and the bottom of the connecting sling segment 37, 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, and the sling assembly also includes a sling connecting plate 42 that passes through the central sling 32, the outward-expanding sling segment 34, the supporting sling segment 35, and the sling assembly also includes a sling connecting plate 42 that passes through the central sling 32, the outward-expanding sling segment 34, the supporting sling segment 35, and the supporting sling segment 36. The rubber sealing sleeves 38 on the inner sides of the rope segments 35, the reinforcement rope segments 36 and the connecting rope segments 37 are all provided with memory core strips 39 in the inner centers of the rubber sealing sleeves 38, the rubber sealing sleeves 38 are all interconnected, and the rubber sealing sleeves 38 are respectively tightly attached to the central rope 32, the outward expansion rope segment 34, the support rope segment 35, the reinforcement rope segment 36 and the connecting rope segment 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 ends of the connecting rope segments 37, the air distribution pipe 41 is connected to the rubber sealing sleeve 38 located inside the connecting rope segment 37, the lower surface center of the sling connecting plate 42 is provided with an air intake pipe 43, the upper end of the air intake pipe 43 is connected to the bottom of the air distribution base 40, and the lower end of the air intake pipe 43 is connected to the air outlet of the high-pressure air pump 44 through a hose; 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 to ensure that the outward-expanding rope segment 34 can be fully expanded and maintain structural strength. The reinforcing rope segment 36 allows 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. The inner sides of the central sling rope 32, the outward expansion sling rope section 34, the support sling rope section 35, the reinforcement sling rope section 36 and the connecting sling rope section 37 are all connected and communicated through the rubber sealing sheath 38 to form a sealed and closed environment. The rubber sealing sheath 38 can be filled with high-pressure gas. The increase of the air pressure in the rubber sealing sheath 38 can enhance 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 pops 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 changes from a rope to a cage, and the strength is further improved after high-pressure inflation, which can effectively avoid the shaking problem in high-altitude operations and make lifting safer and more reliable. The high-pressure air pump 44 is connected to the air inlet pipe 43 through a hose, and inputs the high-pressure airflow into the air distribution base 40, and then disperses into the rubber sealing sheaths 38 in each connecting sling rope segment 37 through the air distribution pipe 41, and then fills into the sling assembly upward 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 wound after hooking the building material, the high-pressure air pump 44 simultaneously performs the air extraction work to re-draw 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; The memory core strip 39 is made of memory material and is used to gather and bounce the sling assembly so that the sling assembly can achieve structural switching from a rope to a cage. Example

[0022] The foot arm reversing mechanism includes a connecting block 4 which 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 corners of the box wall of the gear assembly seat box 9 are all through-set with a slot 10, and the inner side of the slot 10 is exposed with a reversing gear 11, the reversing gear 11 is respectively arranged at the inner four corners of the gear assembly seat box 9, and the bottom shaft end of the reversing gear 11 is connected to a rotary control motor 12, the inner side surface of the connecting block 4 is provided with a sawtooth structure meshing with the reversing gear 11, the upper surface edge of the seat plate 1 and the lower surface edge of the support plate 22 are provided with a slide groove 3, and the upper and lower surfaces of the connecting block 4 are respectively fixed with a slide bar 5 which slidably cooperates with the slide groove 3; 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, effectively and steadily 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 and lower the track wheels 2 to the ground to move the equipment through the movement of the track wheels 2. Instead, the leg arm reversing mechanism can be directly used to adjust the direction of the leg arm 7, and the leg arm hydraulic rod 8 can be used to control the hydraulic extension and retraction of the leg arm 7 to move the position of the entire lifting equipment. This is more suitable for construction sites and the position movement is fast and convenient. Example

[0023] The foot arm anti-vibration mechanism includes a through groove 13 penetrating the side wall of the lower arm part of the foot arm 7, the lower arm part of the foot arm 7 is a hollow structure, and a rubber compression airbag tube 14 is fixedly arranged at the bottom of the lower arm part of the foot arm 7, and a pressing plate 15 is sealed and fixed to the top of the rubber compression airbag tube 14, and the upper surface of the pressing plate 15 is rotatably connected to a connecting hydraulic rod 16, and the other end of the connecting hydraulic rod 16 is rotatably connected to the lower surface of the upper arm part of the foot arm 7. The foot arm anti-vibration mechanism also includes a hinged A ground contact connecting plate 17 at the bottom end of the lower arm portion, a rubber folding air cylinder 18 is fixedly connected to the middle portion below the ground contact connecting plate 17, and a ground contact plate 19 is fixedly connected to the bottom end of the rubber folding air cylinder 18, a limiting guide rod 20 is fixedly connected to the upper surface 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 contact connecting plate 17, a connecting pipe 21 is connected to the upper surface of the ground contact connecting plate 17, and the connecting pipe 21 connects the rubber compression air bag tube 14 and the rubber folding air cylinder 18; The foot arm anti-vibration mechanism is arranged 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 be started again and retracted 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, and 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 is pressed. The rubber compression airbag 14 contracts, so that the air in the rubber compression airbag 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 is stretched 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 good buffering and vibration isolation effects, which is equivalent to adding an air cushion at the bottom of the leg arm 7, so that the leg arm 7 can touch the ground stably while obtaining the protective effect of buffering and vibration isolation, thereby improving the stability of the entire lifting equipment. Example

[0024] A sling pulling roller 29 is rotatably installed at the position of the sling storage bin 28 below the boom 26, and a telescopic protective tube 31 is arranged 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 arranged 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 arranged to be open, and the sling assembly passes through the inside of the telescopic protective tube 31. 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 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 pop open and 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.
