Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for a grain inspection channel in a flat warehouse. Background Technology

[0002] Flat-roofed granaries, as a simple, economical, and practical type of grain storage, are widely used in various grain depots. The grain inspection passage of a flat-roofed granary is located on the upper side, and a staircase is provided on the side of the granary. When inspecting grain, one can climb the staircase to the upper side of the granary, and then open the door of the grain inspection passage to enter the grain inspection passage inside the flat-roofed granary.

[0003] During grain inspection, it is necessary to use related equipment and supplies such as samplers, ventilators, phosphine drugs, and walkway boards. When these devices are brought into or out of the flat warehouse, they all need to be manually carried into the grain inspection passage of the flat warehouse. Because the grain inspection passage of the flat warehouse is high and the stairs are steep, the manual carrying process is time-consuming and laborious. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0005] Therefore, one objective of this utility model is to propose a hoisting device for grain inspection channels in flat warehouses, which aims to solve the problem of time-consuming and labor-intensive manual transport of equipment into flat warehouses during grain inspection in the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a hoisting device for a grain inspection channel in a flat warehouse, comprising an I-beam, a first fixing plate fixedly connected to one side of the I-beam, a movable electric hoist mounted on the surface of the I-beam, first limiting blocks fixedly connected to both sides of the end of the I-beam away from the first fixing plate, a box connected to the hook of the electric hoist, a pull rod fixedly connected to the top of the I-beam, and a second fixing plate fixedly connected to one end of the pull rod.

[0007] The beneficial effects are: after the grain inspection equipment is placed inside the box, it can be hoisted to the top of the stairs outside the grain inspection channel by an electric hoist, so that there is no need for manual climbing of stairs to carry the equipment, thus achieving the purpose of saving time and effort.

[0008] Another embodiment of this utility model provides a hoisting device for a grain inspection channel in a flat warehouse, which further includes a crossbeam. A moving mechanism is installed on the surface of the crossbeam. A first arm and a second arm that are parallel to each other are hinged to the lower part of the moving mechanism. A U-shaped sleeve is hinged to the end of the first arm and the second arm away from the moving mechanism. A storage plate that is parallel to the crossbeam is fixedly connected to the bottom of the U-shaped sleeve. A first hydraulic cylinder is hinged to one side of the first arm. The end of the first hydraulic cylinder away from the first arm is hinged to the bottom of the moving mechanism.

[0009] The beneficial effects are as follows: by adjusting the first and second arms with the first hydraulic cylinder, the first and second arms are tilted, and then, in conjunction with the moving mechanism, the storage plate can be moved to the outside of the flat warehouse. Then, the box containing the grain inspection equipment, which is lifted by the electric hoist, can be placed on top of the storage plate. The box can then be transported into the flat warehouse through the moving mechanism. With the help of the first hydraulic cylinder, the storage plate is lowered, and the grain inspection equipment inside the box can be taken out. Therefore, there is no need to manually carry the grain inspection equipment to the grain inspection channel inside the flat warehouse, thus further saving manpower.

[0010] Preferably, in any of the above embodiments, the crossbeam is connected to diagonal braces on both sides, and the end of the diagonal brace away from the crossbeam is connected to a first positioning seat.

[0011] The beneficial effects are: the diagonal braces reinforce the beams, preventing the beams from sagging and bending due to their large span, thereby improving the structural stability.

[0012] Preferably, in the above scheme, one end of the crossbeam is fixedly connected to a third hinge sleeve, the crossbeam is hinged to a second positioning seat through the third hinge sleeve, a storage groove is provided on the top of the crossbeam, a second hydraulic cylinder is hinged inside the storage groove, the end of the second hydraulic cylinder away from the crossbeam is hinged to the third positioning seat, a clearance groove is provided on the top of the crossbeam, the inclined rod includes a first support rod and a second support rod, the first support rod and the second support rod are hinged end to end, positioning shafts are fixedly connected to both sides of the crossbeam, one end of the first support rod is rotatably sleeved on the outer surface of the positioning shaft, and the first positioning seat is hinged to one end of the second support rod.

[0013] The beneficial effects are as follows: When not in use, the crossbeam can be folded upwards using the second hydraulic cylinder. This frees up space above the grain inspection channel, making the space inside the flat warehouse more spacious and orderly. It also brings the crossbeam closer to the wall of the flat warehouse, thus shifting the center of gravity of the crossbeam, moving mechanism, and other structures closer to the wall. This prevents the crossbeam from bending due to prolonged exposure to a large span, or from loosening at the connection points between the first, second, and third positioning seats and the wall, thereby extending the service life of the equipment.

[0014] Preferably, in the above scheme, an electric push rod is fixedly installed inside the storage slot, and a third limiting block is fixedly connected to the piston rod end of the electric push rod. A slot is provided on one side of the crossbeam at a position corresponding to the third limiting block.

[0015] The beneficial effect is that after the crossbeam is folded upward, the third limiting block limits the moving mechanism, which can prevent the moving mechanism from sliding downward and falling, thus improving safety.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides a hoisting device for grain inspection channels in flat warehouses.

[0030] Example 1:

[0031] like Figure 1 As shown, it includes an I-beam 1, with a first fixing plate 11 fixedly connected to one side of the I-beam 1. The first fixing plate 11 has a through hole, through which expansion bolts can be used to fix it to the outside of the grain inspection passage door of the flat warehouse, thereby fixing the I-beam 1 to the outside of the grain inspection passage of the flat warehouse. A movable electric hoist 2, that is, an electric hoist 2 with a walking function, is installed on the surface of the I-beam 1, so that the electric hoist 2 can move on the I-beam 1 by remote control. The two sides of the end of the I-beam 1 away from the first fixing plate 11 are fixedly connected to... A first limiting block 12 is provided to prevent the electric hoist 2 from slipping off the I-beam 1. A box 21 is connected to the hook of the electric hoist 2. A rope is connected around the top of the box 21. A hanging ring is connected to the top of the rope for attaching to the hook of the electric hoist 2. A pull rod 13 is fixedly connected to the top of the I-beam 1. A second fixing plate 14 is fixedly connected to one end of the pull rod 13. The second fixing plate 14 is provided with a through hole, which can be used to fix the expansion bolt through the through hole to the outside of the grain inspection passage door of the flat warehouse, thereby reinforcing the I-beam 1.

[0032] It should be noted that the electric hoist 2 and its walking mechanism are both existing technologies, including the remote control method of the electric hoist 2. Therefore, the specific structural principle of the electric hoist 2 will not be described in this application.

[0033] The working principle of this embodiment is as follows: In use, after the I-beam 1 is installed outside the grain inspection channel of the flat warehouse, the I-beam 1 extends to the outside of the flat warehouse stairs. By moving the electric hoist 2, the hook of the electric hoist 2 extends to the outside of the stairs. Then, the hook is lowered, and the relevant equipment used for grain inspection is placed into the box 21. Then, the hanging ring on the box 21 is hung on the hook of the electric hoist 2. The electric hoist 2 is then raised to the top of the stairs. Then, the electric hoist 2 is moved so that the box 21 is moved directly above the top of the stairs. Finally, the hook of the electric hoist 2 is lowered, and the box 1 is placed on the top of the stairs. Finally, the equipment in the box 21 is moved into the grain inspection channel.

[0034] Example 2:

[0035] like Figure 2-3 As shown, based on Embodiment 1, it also includes a crossbeam 3. One end of the crossbeam 3 is fixed to the top of the inner side of the grain inspection channel door, that is, inside the flat warehouse. A moving mechanism 4 is installed on the surface of the crossbeam 3. A first arm 5 and a second arm 51, which are parallel to each other, are hinged to the lower part of the moving mechanism 4. The lengths of the first arm 5 and the second arm 51 are equal. A U-shaped sleeve 52 is hinged to the end of the first arm 5 and the second arm 51 away from the moving mechanism 4. A shelf 53, which is parallel to the crossbeam 3, is fixedly connected to the bottom of the U-shaped sleeve 52. Since the first arm 5 and the second arm 51 are parallel to each other and equal, the shelf 53 can always be parallel to the crossbeam 3 when the first arm 5 and the second arm 51 are moved. A first hydraulic cylinder 54 is hinged to one side of the first arm 5. The end of the first hydraulic cylinder 54 away from the first arm 5 is hinged to the bottom of the moving mechanism 4. By extending and retracting the first hydraulic cylinder 54, the tilt angle of the first arm 5 and the second arm 51 can be adjusted, thereby achieving the purpose of adjusting the height of the shelf 53.

[0036] Specifically, such as Figure 2-4 As shown, the moving mechanism 4 includes a U-shaped frame 41, with a roller 42 rotatably connected inside the U-shaped frame 41. A motor 43 is fixedly installed on one side of the U-shaped frame 41, and the output end of the motor 43 is fixedly connected to the shaft of a roller 42. Tracks 31 are fixedly connected to the bottom of both sides of the crossbeam 3. The U-shaped frame 41 is fitted onto the surface of the track 31, and the roller 42 rests on the top of the track 31. The motor 43 can drive the roller 42 to rotate, thereby achieving the purpose of moving the U-shaped frame 41. Second limit blocks 32 are fixedly connected to both sides of one end of the crossbeam 3 to prevent the moving mechanism 4 from slipping off the crossbeam 3.

[0037] Specifically, such as Figure 2-4As shown, a protrusion 44 is fixedly connected to the bottom of the U-shaped frame 41. A first hinge sleeve 45 is fixedly connected to one side of the bottom of the protrusion 44. One end of the first support arm 5 is hinged in the first hinge sleeve 45. A second hinge sleeve 46 is fixedly connected to one side of the protrusion 44. One end of the second support arm 51 is hinged in the second hinge sleeve 46. The tops of the first support arm 5 and the second support arm 6 are staggered, so the first support arm 5 and the second support arm 6 can rotate to a state parallel to the crossbeam 3, thereby raising the shelf 53 to near the crossbeam 3. This can prevent personnel from bumping their heads on the shelf 53 when entering the grain inspection room passage. A first connecting plate 47 is fixedly connected to the bottom of the protrusion 44. A second connecting plate 48 is fixedly connected to one side of the first support arm 5. The two ends of the first hydraulic cylinder 54 are hinged to the first connecting plate 47 and the second connecting plate 48, respectively.

[0038] Preferred, such as Figure 3 As shown, diagonal rods 6 are connected to both sides of the crossbeam 3. The end of the diagonal rod 6 away from the crossbeam 3 is connected to a first positioning seat 61. After the first positioning seat 61 is fixed to the wall inside the flat warehouse by expansion bolts, it can provide tension to the crossbeam 3, thereby achieving the purpose of reinforcing the crossbeam 3.

[0039] The working principle of this embodiment is as follows: When using it, as... Figure 2 As shown, the motor 43 drives the roller 42 to rotate, which moves the moving mechanism 4 towards the grain inspection channel door until the storage plate 53 extends outside the flat warehouse. At this time, the box 21 containing the equipment, lifted by the electric hoist 2, can be placed above the storage plate 53. Then, the moving mechanism 4 transports the box 21 to the inside of the flat warehouse. Finally, by retracting the first hydraulic cylinder 54, the storage plate 53 can be lowered onto the grain inspection channel. Figure 3 As shown, then remove the equipment inside the box 21 to perform the grain inspection operation.

[0040] Example 3:

[0041] like Figure 5-8 As shown, based on Embodiment 2, one end of the crossbeam 3 is fixedly connected to a third hinge sleeve 33. The crossbeam 3 is hinged to a second positioning seat 62 through the third hinge sleeve 33. The second positioning seat 62 is fixed to the wall inside the flat warehouse by expansion bolts. The crossbeam 3 can rotate up and down around the second positioning seat 62. A storage groove 34 is provided on the top of the crossbeam 3. A second hydraulic cylinder 63 is hinged inside the storage groove 34. The end of the second hydraulic cylinder 63 away from the crossbeam 3 is hinged to a third positioning seat 64. The third positioning seat 64 is fixed to the wall inside the flat warehouse by expansion bolts, so that the second hydraulic cylinder 63 can provide support force to the crossbeam 3, ensuring that the angle between the crossbeam 3 and the wall is fixed. Furthermore, by retracting the second hydraulic cylinder 63, the crossbeam 3 can be pulled up and folded upwards. An avoidance groove 35 is provided on the top of the crossbeam 3 to avoid the third positioning seat 64.

[0042] like Figure 5 As shown, the diagonal rod 6 includes a first support rod 601 and a second support rod 602. The first support rod 601 and the second support rod 602 are hinged end to end. When the crossbeam 3 is folded upward, the connection between the first support rod 601 and the second support rod 602 can be bent, thereby ensuring that the crossbeam 3 can be folded upward. Positioning shafts 39 are fixedly connected to both sides of the crossbeam 3. One end of the first support rod 601 is rotatably sleeved on the outer surface of the positioning shaft 39. The first positioning seat 61 is hinged to one end of the second support rod 602. When the crossbeam 3 is in a horizontal state, the first support rod 601 and the second support rod 602 are in a straight line state, which can provide tension to the crossbeam 3 and ensure the stability of the crossbeam 3.

[0043] Preferred, such as Figure 7-8 As shown, an electric push rod 36 is fixedly installed inside the storage slot 34. A third limiting block 37 is fixedly connected to the piston rod end of the electric push rod 36. A slot 38 is opened on one side of the crossbeam 3 at the position corresponding to the third limiting block 37. When the electric push rod 36 is extended, the third limiting block 37 can extend out of the slot 38. Thus, when the crossbeam 3 is folded upward, the third limiting block 37 can block the moving mechanism 4 and prevent the moving mechanism 4 from sliding downward.

[0044] The working principle of this embodiment is as follows: When not in use, the moving mechanism 4 can be moved to a position close to the second limiting block 32. Then, by extending the electric push rod 36, the third limiting block 37 extends to block the moving mechanism 4, extending the first hydraulic cylinder 54 to raise the shelf 53 to a position close to the bottom of the crossbeam 3. Then, the second hydraulic cylinder 63 is retracted, and the crossbeam 3 can be folded upwards. Figure 7 As shown, this frees up space above the grain inspection passage, making the space inside the flat warehouse more spacious and orderly.
