An intelligent lightweight construction hoist

Abstract

The present invention is specifically an intelligent lightweight construction elevator. The assembly frame is composed of four supporting uprights and a top platform. The bottom is placed on the foundation through embedded components. The supporting uprights are assembled by multiple assembly rods. The unique structure of the assembly rods can be quickly assembled and spliced ​​to the required height according to needs. After splicing, a closed oil chamber is formed inside, which can be used in conjunction with the hydraulic system to control the side support plates and movable gear rows of the side support assembly to protrude outward and tighten the inner wall of the sleeve frame to achieve initial braking. This braking can ensure that the left double-layer lifting platform or the right double-layer lifting platform is used stably on the assembly frame and can be placed for falling. On this basis, a fixed gear row is set on the inner side of the tightening sleeve frame to engage with the movable gear row to further improve the tight connection and anti-slip effect; and after the side support plates and movable gear rows of the side support assemblies at other positions of the supporting uprights protrude outward, their positions exceed the inner slide groove diameter of the sleeve frame. Therefore, even if the sleeve frame continues to slide downward, it can be clamped and limited for the second time.

Description

Technical Field

[0001] The present invention specifically relates to an intelligent lightweight construction elevator, and relates to the technical field of dual-lift construction equipment. Background Art

[0002] In the field of modern construction, construction hoists are key equipment for vertical transportation, and their safety and efficiency are of paramount importance. Currently, although intelligent construction hoists are widely equipped with various sensors, their main purpose is to detect the lifting speed of the lifting platform and then trigger the protective structure to prevent the lifting platform from falling, ensuring the safety of construction workers and equipment; however, existing intelligent construction hoists still have significant deficiencies in lifting control, especially in complex application scenarios involving dual lifting platforms. The problem is more prominent. Traditional dual-lift intelligent construction hoists mostly use a single winding crane for lifting and lowering operations. The lifting platform will shake during operation, reducing construction accuracy and efficiency. In addition, the lifting platform lacks dynamic balance during use. In particular, when the crane loses its retraction function, it can easily cause the lifting platform to fall directly. At the same time, the entire frame is slow to build and there is no good braking structure. This control method lacks stability and has a large safety hazard. It is difficult to meet the urgent needs of modern construction for high safety and reliability of equipment. Therefore, it is urgent to propose an intelligent lightweight construction hoist to improve the above problems. Summary of the Invention

A piston is provided at the end of the plug rod and moves with the piston on the inner wall of the movable socket. When the hydraulic system pressurizes the closed oil chamber, the piston, the plug rod, the side support plate and the movable tooth row are pushed outward, and the movable tooth row is used to tightly support the inner side of the frame, and the protruding side support plate and the movable tooth row are used to clamp and limit the bottom opening of the frame.

[0011] According to a further improved solution, the middle of the frame is hollowed out to provide an inner slide groove, which is adapted to be mounted on the outside of the assembly rod. A notch is provided on the inner wall of the inner slide groove corresponding to the side support assembly, and a fixed tooth row is fixed in the notch. When the tooth openings of the movable tooth row protrude outward, they engage with the tooth openings of the fixed tooth row.

[0012] According to a further improved solution, a speed detector is installed on the outer side of the sleeve frame, and the speed detector is arranged at intervals toward one side of the assembly rod.

[0013] In a further improved solution, a hollow opening is opened in the middle of the top platform, and the balancing retraction and extension group includes two rotating shafts installed in the middle of the hollow opening, a middle guide wheel is rotatably installed in the middle of the rotating shaft, and side guide wheels are rotatably installed on both sides of the rotating shaft.

[0014] The first winding elevator and the second winding elevator are respectively installed on the left and right sides of the top platform. The first winding elevator and the second winding elevator are both equipped with a pulling steel rope. The pulling steel rope of the first winding elevator is pulled downward through one of the middle guide wheels and connected to the left double-layer lifting platform. The pulling steel rope of the second winding elevator is pulled downward through the other middle guide wheel and connected to the right double-layer lifting platform. The lifting and lowering of the left and right double-layer lifting platforms are doubly controlled by the relative retraction and extension of the first winding elevator and the second winding elevator.

The left double-deck lifting platform structure includes an upper table top and a lower table top fixedly connected to each other. One side of the upper table top and the lower table top are locked and connected to two frames, and the counterweight block is removable and installed on the lower table top.

[0017] A further improved solution is that a connecting piece is fixedly provided on one side of the upper table top, and a plurality of lifting rings are installed on one side of the connecting piece and are connected to the tensioning steel rope and the balance steel rope, and the two sides of the connecting piece are respectively locked and connected to the two adjacent frames.

The innovative feature of the jacking frame is that the supporting posts are assembled by multiple assembling posts. The unique structure of the assembling posts can be quickly assembled and spliced ​​to the required height according to needs. After splicing, a closed oil chamber is formed inside, which can be used in conjunction with the hydraulic system to control the side support plates and the movable gear row of the side support assembly to protrude outwards and press against the inner wall of the sleeve frame to achieve initial braking. This braking can ensure that the left double-layer lifting platform or the right double-layer lifting platform is used stably on the jacking frame and can be placed for falling. On this basis, a fixed gear row is provided on the inner side of the tightening sleeve frame to engage with the movable gear row to further improve the tight connection and anti-slip effect. After the side support plates and the movable gear row of the side support assemblies at other positions of the supporting posts protrude outwards, their positions exceed the inner slide groove diameter of the sleeve frame. Therefore, even if the sleeve frame continues to slide downward, it can be clamped and limited for the second time, which greatly avoids the risk of the left double-layer lifting platform and the right double-layer lifting platform falling.

[0020] The left and right double-deck lifting platforms can be lifted and lowered by the lift when the first and second reels are in contact with each other, thereby ensuring that the lift is lifted and lowered smoothly.

[0021] Counterweights are configured on the left and right double-deck lifting platforms, and the weight on both sides can be flexibly adjusted according to needs, thereby better ensuring lifting stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figure 1-7 As shown, the present invention provides an intelligent lightweight construction elevator, including an assembly frame formed by four supporting poles 2 and a top platform 3 fixed to each other, an embedded component 1 fixed to the bottom of each supporting pole 2, and the embedded component 1 is buried in the concrete foundation to form a stable rectangular support frame, wherein the left double-layer lifting platform 4 and the right double-layer lifting platform 5 are respectively slidably lifted and lowered on the left and right sides of the assembly frame, and each supporting pole 2 is provided with a sleeve frame 6, and the left double-layer lifting platform 4 and the right double-layer lifting platform 5 are respectively locked and connected to the outer sides of the two sleeve frames 6 on the left and right sides, so that the left double-layer lifting platform 4 passes through the two left sleeve frames 6 is slidingly arranged on the two left support poles 2, and the right double-layer lifting platform 5 is slidingly arranged on the two right support poles 2 through the two right sleeve frames 6, realizing the lifting operation structure of "single frame and double platforms"; wherein a plurality of side support assemblies 20 are respectively arranged on the left and right sides of each support pole 2, and the top platform 3 is provided with a hydraulic system 8, and the hydraulic system 8 controls each of the plurality of side support assemblies 20 to protrude outward and tighten the inner side of the sleeve frame 6 connecting the left double-layer lifting platform 4 and the right double-layer lifting platform 5 synchronously, and after the side support assemblies 20 protrude outward, they clamp the bottom opening of the limit sleeve frame 6 to prevent it from moving downward;

[0033] Specifically, the support pole 2 is composed of a plurality of assembly rods 21 spliced ​​together. An upper plug-in groove 22 is provided on the top of the support pole 2, and a raised plug-in block 23 adapted to the upper plug-in groove 22 is provided at the bottom of the support pole 2. A recessed groove 24 is provided in the middle of the front and rear sides of the support pole 2, and a connecting hole 25 is provided on the upper and lower side walls of the recessed groove 24. When the raised plug-in block 23 of the upper assembly pole 21 is adapted to be inserted into the upper plug-in groove 22, a bolt is passed through the connecting hole 25 between the two assembly poles 21 to lock each other to form a whole. That is to say, when splicing the support poles 2, the bottom assembly pole 21 of the support pole 2 is fixed to the embedded component 1, and the embedded component 1 is then Buried in the concrete foundation, the assembly rod 21 in the middle of the supporting pole 2 is adapted to be plugged in through the adjacent upper plug-in groove 22 and the raised plug block 23, and the two assembly rods 21 are locked together by bolts inserted through the adjacent connecting holes 25, and quickly assembled and spliced ​​to the required height as needed. During this period, the sleeve frame 6 needs to be correspondingly sleeved on the assembly rod 21. Later, the corresponding left double-layer lifting platform 4 and right double-layer lifting platform 5 on both sides are installed, and the assembly rod 21 at the top of the supporting pole 2 is fixed together with the top platform 3 to form a fixed support at the top. Through the unique structure of the assembly rod 21, the entire assembly frame can be easily and quickly built up, thereby improving the overall use effect.

[0034] Furthermore, each assembly rod 21 has a closed oil chamber 26 in the middle that is interconnected. The closed oil chambers 26 are correspondingly distributed in the middle of the upper plug-in groove 22 and the raised plug-in block 23. A sealing gasket is provided on the inner side of the upper plug-in groove 22 to be connected to the raised plug-in block 23. A plurality of sliding embedding grooves 27 are provided on the left and right sides of the assembly rod 21. The side support assembly 20 is movably embedded in the inner side of the sliding embedding groove 27, and a movable socket 28 is laterally provided on one side of the sliding embedding groove 27 and is connected to the closed oil chamber 26. The hydraulic station 81 is tightly connected to the closed oil chamber 26 at the top of the supporting upright 2 through a hydraulic pipe 82. In this way, the hydraulic system 8 can pressurize or depressurize the closed oil chamber 26 to realize the side support assembly 20 protruding outward or retracting inward, thereby achieving the tightening and limiting effect on the sleeve frame 6.

[0035] Specifically, the side support assembly 20 includes a side support plate 200, a movable tooth row 201 is fixedly provided on the outer side of the side support plate 200, and a limiting protrusion 202 is integrally provided on the upper and lower sides of the side support plate 200, and the side support plate 200 and the limiting protrusion 202 are slidably embedded in the inner side of the sliding embedding groove 27, and a plug rod 203 is fixedly provided on one side of the side support plate 200 and inserted into the movable socket 28, and a piston 204 is provided at the end of the plug rod 203 to move with the inner wall of the movable socket 28. Therefore, when the hydraulic system 8 pressurizes the closed oil chamber 26, it pushes the piston 204, the plug rod 203, the side support plate 200 and the movable tooth row 201 to protrude outward, and uses the movable tooth row 201 to support the inner side of the sleeve frame 6, and uses the side support plate 200 and the movable tooth row 201 protruding from other parts to synchronously clamp and limit the bottom openings of the four sleeve frames 6 to prevent further sliding and falling.

[0036] Among them, in order to improve the connection effect between the side support assembly 20 and the sleeve frame 6, an inner slide groove 61 is hollowed out in the middle of the sleeve frame 6, and the inner slide groove 61 is adapted to be arranged on the outside of the assembly rod 21. A notch 62 is provided on the inner wall of the inner slide groove 61 corresponding to the side of the side support assembly 20. The notch 62 is fixed with a fixed tooth row 63. When the teeth of the movable tooth row 201 protrude outward, they engage with the teeth of the fixed tooth row 63, which can further improve the connection tightness and anti-slip effect between the two.

[0037] Furthermore, a speed detector 64 is installed on the outside of the sleeve 6, spaced apart and arranged toward the side of the assembly rod 21. When the sleeve 6 falls too fast, a signal is fed back to the control system. The control system then initiates an emergency start of the hydraulic system 8 to pressurize the sealed oil chamber 26, allowing the side support assemblies 20 supporting the four uprights 2 to automatically and synchronously protrude outward to tighten or limit the four sleeves 6, greatly improving safety in use.

[0038] In this embodiment, the first winding elevator 74 and the second winding elevator 75 are respectively installed on the left and right sides of the top platform 3. The first winding elevator 74 and the second winding elevator 75 are both equipped with a pulling steel rope 9. The pulling steel rope 9 of the first winding elevator 74 is pulled downward through one of the middle guide wheels 72 and connected to the left double-layer lifting platform 4. The pulling steel rope 9 of the second winding elevator 75 is pulled downward through the other middle guide wheel 72 and connected to the right double-layer lifting platform 5. The relative retraction and expansion of the first winding elevator 74 and the second winding elevator 75 can dually control the lifting and lowering of the left double-layer lifting platform 4 and the right double-layer lifting platform 5. This makes lifting simpler and more stable, and the alternating service life is longer.

[0039] Furthermore, a hollow opening 31 is provided in the middle of the top platform 3, and the balancing retracting and releasing group 7 includes two rotating shafts 71 installed in the middle of the hollow opening 31, a middle guide wheel 72 is rotatably installed in the middle of the rotating shaft 71, and side guide wheels 73 are rotatably installed on both sides of the rotating shaft 71. Two balancing steel ropes 10 are provided and are respectively hung on the side guide wheels 73 on both sides of the two rotating shafts 71, forming a closed-loop traction structure, which can dynamically maintain the force balance and movement synchronization of the lifting platforms on both sides, so that even if the first winding elevator 74 and the When the second winding elevator 75 loses its retracting and releasing function, the left double-layer lifting platform 4 and the right double-layer lifting platform 5 are both in a falling state, which can offset most of each other's mass, so it is not easy to fall downward quickly. Moreover, when the mass of the left double-layer lifting platform 4 and the right double-layer lifting platform 5 on both sides of the series connection is almost the same, they can be hung on the top platform 3 in a balanced manner. Moreover, the design of the balancing force, combined with the first winding elevator 74 and the second winding elevator 75, can also easily pull the left double-layer lifting platform 4 and the right double-layer lifting platform 5 in series.

[0040] Further improvements have been made, with the left double-deck lifting platform 4 and the right double-deck lifting platform 5 having the same structure. The left double-deck lifting platform 4 structure includes an upper table 41 and a lower table 42 that are fixedly connected to each other. One side of the upper table 41 and the lower table 42 are both locked and connected to the two sleeves 6, wherein a counterweight block 43 is detachably mounted on the lower table 42. The counterweight block 43 can be used to temporarily and flexibly counterweight both sides of the left double-deck lifting platform 4 and the right double-deck lifting platform 5, so that they can reach a balance point, allowing the winding and lifting operations of the first winding elevator 74 and the second winding elevator 75 to be more smoothly processed. In addition, a connector 44 is fixed on one side of the upper table 41, and a plurality of lifting rings 45 are installed on one side of the connector 44 and are connected to the tensioning steel rope 9 and the balance steel rope 10. The two sides of the connector 44 are locked and connected to the two adjacent sleeves 6, thereby ensuring the integrity of the two sleeves 6 and the upper table 41, improving the structural strength and the synchronization of use.

[0041] In a more specific embodiment, when the present invention is in use, the first winding elevator 74 pulls the left double-layer lifting platform 4 up by the winding steel rope 9, and the second winding elevator 75 synchronously lowers the right double-layer lifting platform 5 by the winding steel rope 9. Since the left double-layer lifting platform 4 and the right double-layer lifting platform 5 are hung on the two side guide wheels 73 of the two rotating shafts 71 by two balancing steel ropes 10, so that part of the weight between them will offset each other to form a balancing force, so the first winding elevator 74 or the second winding elevator 75 can easily control the left double-layer lifting platform 4 and the right double-layer lifting platform 5 to move forward. The left double-layer lifting platform 4 and the right double-layer lifting platform 5 are connected to the four supporting uprights 2 in a sliding manner through the sleeve frame 6, so that they can realize stable and independent lifting and lowering guidance. At the same time, since the fixed gear row 63 is installed on the inner side of the sleeve frame 6, when the hydraulic station 81 pressurizes the closed oil chamber 26 of the four supporting uprights 2 through the hydraulic pipe 82, the oil pressure can push the piston 204 on each plug rod 203 to move outward along the movable socket 28, and simultaneously push the side support plate 200, the limiting protrusion 202 and the movable gear row 201 to move outward along the sliding embedding groove 27, so that the side support The plate 200 and the movable tooth row 201 protrude outward from the outer surface of the assembly rod 21. When the sleeve frames 6 of the left double-layer lifting platform 4 and the right double-layer lifting platform 5 are located at the corresponding position of the protruding movable tooth row 201, the movable tooth row 201 can directly adapt to the fixed tooth row 63 that bites and presses against the inner wall of the sleeve frame 6, which can preliminarily brake each sleeve frame 6, thereby improving the stability of the left double-layer lifting platform 4 and the right double-layer lifting platform 5 on the four supporting uprights 2; and the side support plates 200 and the movable tooth row 201 that protrude outward from the other parts of the supporting uprights 2 are staggered from the corresponding positions of the sleeve frames 6, but their protruding The position after coming out exceeds the diameter of the inner slide groove 61 of the sleeve frame 6. Therefore, when the left double-layer lifting platform 4 and the right double-layer lifting platform 5 fall, the sleeve frame 6 can be clamped and limited for the second time when it continues to slide downward. Of course, the speed detector 64 can also be used to detect the lifting and lowering speed of the left double-layer lifting platform 4 and the right double-layer lifting platform 5 in real time. When it exceeds the rated value, the hydraulic system 8 can be triggered to urgently pressurize the closed oil chamber 26 of the supporting upright 2, which greatly avoids the risk of the left double-layer lifting platform 4 and the right double-layer lifting platform 5 falling, making the use of the entire intelligent double-deck lift more stable and safe.

[0042] The above embodiments show and describe the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected.
