Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and specifically to an elevator for water conservancy construction. Background Art

[0002] An elevator is one of the indispensable important devices in water conservancy project construction. It is a vertical transportation device used at the construction site of water conservancy projects and can transport a large amount of building materials, such as cement, sand, stones, steel bars, etc. These materials are usually heavy and need to be transported from the ground to the required construction height by the elevator to provide raw material support for water conservancy construction.

[0003] In the lifting and transportation of materials by existing elevators for water conservancy construction, most of the hoppers are set with open tops for easy loading and unloading of materials. However, during the lifting process, due to the action of mechanical vibration and external wind pressure, there is a risk of the internal materials in the open hopper falling. The falling materials may damage surrounding instruments or even hit workers, resulting in a low safety factor.

[0004] A construction elevator disclosed in the Chinese invention patent application publication specification CN112374427B has its own weight controlled at an extremely low level, and it is significantly adaptable when applied to high-rise or super-high-rise buildings. The elevator has high working efficiency, excellent performance, low cost, and to a certain extent makes up for the deficiencies in the domestic construction elevator market. However, the above solution cannot perform continuous and uninterrupted feeding and discharging operations. When traditional elevators perform feeding and discharging, the materials need to be loaded into the hopper at the bottom and lifted to the top. After the hopper stays at the top and the materials are unloaded from the hopper, the hopper can be lowered to the bottom for loading operations. The feeding and discharging operations cannot be carried out simultaneously, which wastes time. And traditional elevators need manual or external instruments to assist in unloading when staying at the top for unloading, making the unloading process slower. Therefore, we propose an elevator for water conservancy construction to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to make up for the deficiencies of the existing technology and propose an elevator for water conservancy construction. This device can enable two hoppers to perform continuous and uninterrupted feeding and discharging operations. Compared with traditional elevators, which need to stay at the top for unloading before descending for loading operations, it saves a lot of time. At the same time, the hopper can be tilted at the top to assist in unloading, which is more convenient. And during the lifting process of the hopper, the cover plate seals the opening above the hopper to prevent the materials in the hopper from falling due to mechanical vibration or external wind pressure.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a lift for water conservancy construction, including a lifting frame, on the outer surface of which a semi-circular platform is fixed. There are two loading components arranged outside the semi-circular platform. The loading component includes a hopper, and a sealing door is hinged on the inner wall of the hopper. Materials for water conservancy construction can be placed in the hopper for transportation.

[0007] An unloading component is arranged inside the semi-circular platform. The unloading component includes a hollow box, a hydraulic rod fixed on the inner bottom wall of the semi-circular platform, and two guide rail frames fixed on the inner wall of the semi-circular platform. Through the unloading component, the hoppers on both sides can be rotated and displaced, and the hopper moves outward and tilts when unloading.

[0008] Two symmetrically arranged convex blocks are fixed on the outer surface of the semi-circular platform. A fixing frame is fixed on the outer surface of the semi-circular platform. Two symmetrically arranged inclined panels are fixed on the inner wall of the fixing frame, and a baffle is fixed on the inner wall of the fixing frame. When the hopper is pushed by the unloading component, under the action of the inclined panel and the baffle, the sealing door can be opened to facilitate unloading.

[0009] A lifting component is arranged inside the semi-circular platform. The lifting component includes a lifting platform slidably connected to the inner wall of the semi-circular platform. When the hopper is lifted, the hopper can be limited on the lifting platform through the lifting component.

[0010] An L-shaped frame is fixed on the outer surface of the lifting frame. Two L-shaped stoppers are fixed on the outer surface of the lifting frame. An anti-falling component is arranged above the lifting component. The anti-falling component includes a cover plate, a retaining frame, and two guide frames. During the lifting process of the hopper, the cover plate can cover the hopper to prevent the materials in the hopper from falling.

[0011] Preferably, a clamping block is fixed on the outer surface of the hopper, an arc-shaped block is fixed on the bottom surface of the hopper, two symmetrically arranged limit seats are fixed on the outer surface of the hopper. U-shaped limit rods are slidably connected to the inner walls of the two limit seats respectively. Inclined blocks are fixed on the outer surfaces of the two U-shaped limit rods. The inclined blocks are adapted to the inclined panels. Two limit plates are fixed on the outer surface of the sealing door, and the two limit plates are respectively adapted to the two U-shaped limit rods.

[0012] By adopting the above technical solution, when the U-shaped limit rod is inserted into the limit plate, the closed sealing door can be limited.

[0013] Furthermore, first springs are fixed on the outer surfaces of the two limit seats respectively. The ends of the two first springs far away from the limit seats are respectively fixed on the outer surfaces of the two inclined blocks.

[0014] By adopting the above technical solution, the first springs are always in a compressed state, preventing the U-shaped limit rods from disengaging from the limit plates.

[0015] Further, two symmetric second springs are fixed on the outer surface of the sealing door, and one end of each of the two second springs away from the sealing door is fixed on the outer surface of the hopper.

[0016] By adopting the above technical solution, when the sealing door is in the closed state, the second springs are in a slightly stretched state, and the second springs can ensure that the sealing door can reset and close after the hopper unloads materials.

[0017] Specifically, a rotating column is rotatably connected to the inner wall of the hollow box. A rotating frame is fixed to the top end of the rotating column. The rotating frame is adapted to the clamping block. A sliding seat is fixed to the bottom surface of the hollow box. Both of the two sliding seats are slidably connected to the guide rail frame.

[0018] By adopting the above technical solution, under the sliding action of the sliding seat and the guide rail frame, when the hydraulic rod extends, the hollow box first moves horizontally and then tilts.

[0019] Further, a moving frame is fixed to the telescopic end of the hydraulic rod. Two slide rails are slidably connected to the inner wall of the moving frame. Both of the two slide rails are fixed to the inner bottom wall of the semi-circular platform.

[0020] By adopting the above technical solution, the slide rails play a guiding role for the movement of the moving frame.

[0021] A fixed seat is fixed to the upper surface of the above-mentioned moving frame. The hollow box is hinged to the outer surface of the fixed seat. An arc-shaped hinge seat is hinged to the inner wall of the fixed seat. The arc-shaped hinge seat is adapted to the arc-shaped block. A fixing plate is fixed to the upper surface of the moving frame. Two third springs are fixed to the outer surface of the fixing plate. One end of each of the two third springs away from the fixing plate is fixed to the outer surface of the arc-shaped hinge seat.

[0022] By adopting the above technical solution, when the arc-shaped hinge seat is in the vertical state, the third springs are in a slightly compressed state. The setting of the third springs can keep the arc-shaped hinge seat vertical without external force.

[0023] Further, a motor is fixed to the inner wall of the hollow box. A first bevel gear is fixed to the output shaft end of the motor. A second bevel gear is fixed to the outer surface of the rotating column. The first bevel gear meshes with the second bevel gear.

[0024] By adopting the above technical solution, when the motor runs, it can drive the rotating column to rotate through the first bevel gear and the second bevel gear.

[0025] Specifically, a U-shaped seat is fixed to the inner wall of the lifting platform. A limiting claw is hinged to the bottom surface of the lifting platform. The limiting claw is adapted to the convex block. Both the U-shaped seat and the limiting claw are adapted to the arc-shaped block. Two fourth springs are fixed to the outer surface of the limiting claw. One end of each of the two fourth springs away from the limiting claw is fixed to the bottom surface of the lifting platform.

[0026] By adopting the above technical solution, when the limiting claw is inserted into the U-shaped seat and the arc-shaped block, the fourth spring is in a slightly stretched state, ensuring the stability of the limiting claw inserted into the U-shaped seat and the arc-shaped block.

[0027] Preferably, a fixing rod is fixed to the inner wall of the retaining frame. The fixing rod penetrates through the cover plate and is rotatably connected to the cover plate. The retaining frame is adapted to the cover plate. Both of the guiding frames penetrate through the retaining frame and are slidably connected to the retaining frame. The L-shaped frame is adapted to the cover plate. Both of the L-shaped retaining blocks are adapted to the retaining frame.

[0028] By adopting the above technical solution, when the hopper rises to the top, the L-shaped frame pushes the cover plate to rotate and open, facilitating the replacement of the two hoppers. When the hopper drops to the bottom, the L-shaped retaining block pushes the retaining frame and the cover plate to open, facilitating the loading of the hopper.

[0029] Compared with the prior art, the water conservancy construction elevator has the following beneficial effects:

[0030] First, through the settings of the lifting frame, semi-circular platform, loading assembly, unloading assembly and lifting assembly in the present invention, after the bottom hopper is loaded, it is lifted to the top. Through the unloading assembly, the empty hopper above the semi-circular platform is replaced with the hopper loaded on the lifting platform, and then the empty hopper is lowered for loading, while the loaded hopper is unloaded, enabling the two hoppers to continuously and uninterruptedly perform loading and unloading operations. Compared with the traditional elevator where the hopper stays at the top for unloading before it can descend for loading operation, it saves a lot of time. At the same time, the hopper can be tilted at the top to assist in unloading, which is relatively convenient.

[0031] Second, through the setting of the anti-falling assembly in the present invention, when the hopper rises to the top, the L-shaped frame pushes the cover plate to rotate and open, facilitating the replacement of the two hoppers. When the hopper drops to the bottom, the L-shaped retaining block pushes the retaining frame and the cover plate to open, facilitating the loading of the hopper. And during the lifting process of the hopper, the cover plate seals the opening above the hopper, preventing the materials in the hopper from falling from the opening above the hopper due to mechanical vibration or external wind pressure, with a relatively high safety factor.

[0032] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

[0056] Please pay special attention to Figure 10 and Figure 11, on the outer surfaces of both limiting seats 34, a first spring 37 is fixed. The ends of the two first springs 37 away from the limiting seats 34 are respectively fixed on the outer surfaces of the two inclined blocks 36. The first spring 37 is always in a compressed state to prevent the U-shaped limiting rod 35 from detaching from the limiting plate 38.

[0057] Please refer specifically to Figure 5 and Figure 9 , on the outer surface of the sealing door 32, two symmetric second springs 39 are fixed. The ends of the two second springs 39 away from the sealing door 32 are both fixed on the outer surface of the hopper 31. When the sealing door 32 is in the closed state, the second spring 39 is in a slightly stretched state. The second spring 39 can ensure that the sealing door 32 can reset and close after the hopper 31 discharges materials.

[0058] Please refer specifically to Figure 6 , Figure 8 , Figure 9 and Figure 12 , inside the semi-circular platform 2, a discharging assembly 4 is arranged. The discharging assembly 4 includes a hollow box 41, a hydraulic rod 42 fixed on the inner bottom wall of the semi-circular platform 2, and two guide rail frames 49 fixed on the inner wall of the semi-circular platform 2. The inner wall of the hollow box 41 is rotationally connected with a rotating column 43. The top end of the rotating column 43 is fixed with a rotating frame 44. The rotating frame 44 is adapted to the clamping block 33. After the clamping block 33 is inserted into the rotating frame 44, the rotating frame 44 can drive the clamping block 33 and the hopper 31 to rotate and move. Through the discharging assembly 4, the hoppers 31 on both sides can be rotated and displaced. And when the hopper 31 moves above the hollow box 41, under the push of the hydraulic rod 42, the hopper 31 can move outwards and tilt.

[0059] Please refer specifically to Figure 9 and Figure 12 , on the bottom surface of the hollow box 41, a sliding seat 48 is fixed. Both sliding seats 48 are slidably connected with the guide rail frames 49. Under the sliding action of the sliding seats 48 and the guide rail frames 49, when the hydraulic rod 42 extends, the hollow box 41 first moves horizontally and then tilts.

[0060] Please refer specifically to Figure 13 , the telescopic end of the hydraulic rod 42 is fixed with a moving frame 45. The inner wall of the moving frame 45 is slidably connected with two slide rails 410. Both slide rails 410 are fixed on the inner bottom wall of the semi-circular platform 2. The slide rails 410 play a guiding role for the movement of the moving frame 45.

[0061] Please refer specifically to Figure 12, a fixed seat 46 is fixed on the upper surface of the moving frame 45. The hollow box 41 is hinged on the outer surface of the fixed seat 46. An arc-shaped hinge seat 47 is hinged on the inner wall of the fixed seat 46. The vertical state of the arc-shaped hinge seat 47 is the limit state, and the arc-shaped hinge seat 47 cannot rotate further towards the direction close to the hollow box 41. The arc-shaped hinge seat 47 is adapted to the arc-shaped block 310. When the rotating frame 44 drives the clamping block 33 and the hopper 31 to rotate, the arc-shaped block 310 can slide into the arc-shaped hinge seat 47. A fixing plate 411 is fixed on the upper surface of the moving frame 45. Two third springs 412 are fixed on the outer surface of the fixing plate 411. One end of each of the two third springs 412 away from the fixing plate 411 is fixed on the outer surface of the arc-shaped hinge seat 47. When the arc-shaped hinge seat 47 is in the vertical state, the third spring 412 is in a slightly compressed state. The setting of the third spring 412 can keep the arc-shaped hinge seat 47 vertical without external force.

[0062] Please refer specifically to Figure 13 , a motor 413 is fixed on the inner wall of the hollow box 41. A first bevel gear 414 is fixed on the output shaft end of the motor 413. A second bevel gear 415 is fixed on the outer surface of the rotating column 43. The first bevel gear 414 meshes with the second bevel gear 415. When the motor 413 operates, it can drive the rotating column 43 to rotate through the first bevel gear 414 and the second bevel gear 415.

[0063] Please refer specifically to Figure 8 and Figure 10 , two symmetrically arranged convex blocks 21 are fixed on the outer surface of the semi-circular platform 2. A fixing frame 22 is fixed on the outer surface of the semi-circular platform 2. Two symmetrically arranged inclined panels 23 are fixed on the inner wall of the fixing frame 22. A baffle 24 is fixed on the inner wall of the fixing frame 22. When the discharging assembly 4 pushes the hopper 31, under the action of the inclined panel 23 and the baffle 24, the sealing door 32 can be opened to facilitate discharging. When the hydraulic rod 42 pushes the hopper 31 to move, the hopper 31 moves horizontally, and the inclined plane block 36 first contacts the inclined panel 23, so that the U-shaped limiting rod 35 releases the limit on the limiting plate 38. Then the hopper 31 tilts, and the sealing door 32 contacts the baffle 24, and the sealing door 32 is separated from the hopper 31 and opened.

[0064] Please refer specifically to Figure 3 , Figure 5 , Figure 6 and Figure 7, a lifting component 5 is arranged inside the semi-circular table 2. The lifting component 5 includes a lifting platform 51 slidably connected to the inner wall of the semi-circular table 2. The lifting platform 51 can be lifted and moved through a winch, a rope and a guiding track on the lifting frame 1. A U-shaped seat 52 is fixed to the inner wall of the lifting platform 51. A limiting claw 54 is hinged to the bottom surface of the lifting platform 51. The limiting claw 54 is adapted to the convex block 21. Both the U-shaped seat 52 and the limiting claw 54 are adapted to the arc-shaped block 310. When the hopper 31 is lifted, the hopper 31 can be limited on the lifting platform 51 by the limiting of the arc-shaped block 310 by the limiting claw 54, ensuring the stability of the hopper 31 during lifting.

[0065] Please refer particularly to Figure 7 , two fourth springs 53 are fixed to the outer surface of the limiting claw 54. One ends of the two fourth springs 53 far from the limiting claw 54 are both fixed to the bottom surface of the lifting platform 51. When the limiting claw 54 is inserted into the U-shaped seat 52 and the arc-shaped block 310, the fourth springs 53 are in a slightly stretched state, ensuring the stability of the limiting claw 54 inserted into the U-shaped seat 52 and the arc-shaped block 310.

[0066] Please refer particularly to Figure 1 、 Figure 3 and Figure 4 , an anti-falling component 6 is arranged above the lifting component 5. The anti-falling component 6 includes a cover plate 61, a retaining frame 62 and two guiding frames 63. During the lifting process of the hopper 31, the cover plate 61 can cover the hopper 31 to prevent the materials in the hopper 31 from falling due to mechanical vibration or external wind pressure. And when the hopper 31 moves to the top or bottom of the lifting frame 1, the cover plate 61 remains open to avoid affecting the loading and unloading of the hopper 31.

[0067] Please refer particularly to Figure 3 and Figure 4 , a fixing rod 64 is fixed to the inner wall of the retaining frame 62. The fixing rod 64 penetrates through the cover plate 61 and is rotatably connected to the cover plate 61. The retaining frame 62 is adapted to the cover plate 61. When the cover plate 61 is not affected by external forces, it will remain horizontal under the blocking action of the retaining frame 62. Both of the two guiding frames 63 penetrate through the retaining frame 62 and are both slidably connected to the retaining frame 62. The L-shaped frame 11 is adapted to the cover plate 61. Both of the two L-shaped stoppers 12 are adapted to the retaining frame 62. When the hopper 31 rises to the top, the L-shaped frame 11 pushes the cover plate 61 to rotate and open, facilitating the replacement of the two hoppers 31. When the hopper 31 falls to the bottom, the L-shaped stopper 12 pushes the retaining frame 62 and the cover plate 61 to open, facilitating the loading of the hopper 31.

[0068] Working principle: First, load the hopper 31 at the bottom of the lifting frame 1. At this time, the L-shaped block 12 separates the blocking frame 62, and the cover plate 61 is separated from the hopper 31. Then, the hopper 31 is lifted and contacts the cover plate 61, so that the cover plate 61 seals the opening of the hopper 31 and continues to lift. When the hopper 31 is about to be lifted to the top of the lifting frame 1, the L-shaped frame 11 first contacts the cover plate 61 and pushes the cover plate 61 to rotate and open. At the same time, the limit claw 54 contacts the convex block 21, so that the convex block 21 pushes the limit claw 54 to rotate, and the limit claw 54 is pulled out of the arc-shaped block 310. At the same time, the clamping block 33 is inserted into the rotating frame 44. At this time, control the motor 413 to operate, drive the rotating frame 44 to rotate, so that the hopper 31 on the semi-circular platform 2 and the hopper 31 on the lifting platform 51 are rotated and displaced. The lifting platform 51 drives the displaced hopper 31 to move down for reloading, and then control the hydraulic rod 42 to extend, driving the moving frame 45, the hollow box 41 and the hopper 31 to move horizontally first;

[0069] When the inclined panel 23 pushes the inclined block 36 to move towards the limit seat 34, the limit on the limit plate 38 and the sealing door 32 is released. The hopper 31, the hollow box 41, and the sliding seat 48 tilt along the track of the guide rail frame 49, and the sealing door 32 contacts the baffle 24. The baffle 24 pushes the sealing door 32 to open, and the material in the hopper 31 is poured downward. Then, the hydraulic rod 42 contracts to reset the hopper 31 and the sealing door 32. At this time, the clamping block 33 on the lifting frame 1 is loaded and lifted to the top of the lifting frame 1. The rotating frame 44 drives the two hoppers 31 to rotate and displace, and then repeats the feeding and discharging process. This device can enable the two hoppers 31 to continuously and uninterruptedly perform feeding and discharging operations, saving a lot of time. At the same time, the hopper 31 can be tilted at the top to assist in discharging, which is more convenient. And when the hopper 31 is lifted, the cover plate 61 seals the opening above the hopper 31, preventing the material in the hopper 31 from falling from the opening above the hopper 31 due to mechanical vibration or external wind pressure, and the safety factor is relatively high.

[0070] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
