Description

Technical Field

[0001] This invention relates to the field of hoisting and handling equipment technology, and in particular to a handling vehicle for hoisting an oil-free scroll air compressor. Background Technology

[0002] Oil-free scroll air compressors are air compression devices that utilize the scroll compression principle, eliminating the need for lubricating oil throughout the compression process. They rely on the meshing rotation of moving and stationary scrolls to create continuous, closed-loop volume changes, achieving air intake, compression, and discharge. The entire internal compression chamber is oil-free, outputting pure, oil-free compressed air. They feature a compact structure, low vibration, low noise, stable operation, and easy maintenance, distinguishing them from traditional oil-lubricated air compressors by eliminating oil and gas pollution at the source.

[0003] In scenarios where the position of an oil-free scroll air compressor needs to be adjusted during transportation and installation, the large size and heavy weight of the compressor make it difficult to move and position manually. To facilitate operation, it is necessary to hoist and transport the compressor to the designated installation location in the machine room.

[0004] Existing hoisting methods for oil-free scroll air compressors typically involve directly securing the entire unit with ropes before using lifting equipment. However, this method is cumbersome, and the unit's stability is poor during hoisting, increasing the risk of rope slippage and compromising safety. While some methods use hoisting frames, moving the unit to the inside of the frame still requires manual labor with a small trolley. Due to the unit's weight, manual pushing is labor-intensive, and the lack of a stabilizing restraint structure for the compressor wheels during this process increases the risk of accidental displacement and compromises safety. Therefore, this application provides a hoisting vehicle for oil-free scroll air compressors to meet these requirements. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a transport vehicle for hoisting oil-free scroll air compressors.

[0006] To achieve the above objectives, this application provides the following technical solution: a transport vehicle for hoisting an oil-free scroll air compressor, comprising a transport vehicle, a transport plate movably mounted on the transport vehicle, and a hoisting frame that can be connected to the transport plate, wherein the hoisting frame forms a space that can accommodate the transport vehicle and the transport plate to move in and out simultaneously.

[0007] The transfer plate is provided with two sets of symmetrically distributed clamping frames. Each set of clamping frames consists of two frames, and each clamping frame has an open trapezoidal structure. The two sets of clamping frames can move synchronously in opposite directions to achieve the purpose of engaging or disengaging from the oil-free scroll air compressor wheel body.

[0008] The transfer plate is provided with a first comb tooth docking frame and a second comb tooth docking frame on both sides respectively. The hoisting frame is provided with a comb tooth docking groove that can be adapted to the first comb tooth docking frame and the second comb tooth docking frame. The first comb tooth docking frame and the second comb tooth docking frame can rotate synchronously in opposite directions. When the transfer car and the transfer plate move into the inner side of the hoisting frame synchronously, the first comb tooth docking frame and the second comb tooth docking frame are flipped from above the transfer plate to the inner side of the comb tooth docking groove.

[0009] Furthermore, each set of the card slots is connected by an extension rod, and the transfer plate has a channel for the two extension rods to move through, with both extension rods extending through the channel to the bottom of the transfer plate.

[0010] Both of the extension rods are equipped with guide racks that can move synchronously with them at their bottom. The two guide racks are arranged diagonally and parallel to each other, and the same guide gear is meshed on the inner side of the two guide racks. The guide gear is mounted below the transfer plate, and an electric push rod for driving one of the two guide racks to move is mounted below the transfer plate.

[0011] Furthermore, the bottom of the transfer plate is equipped with two parallel guide rails, and the two guide racks are slidably assembled with the two guide rails respectively.

[0012] Furthermore, the first comb tooth docking frame and the second comb tooth docking frame are respectively fixed with a first bracket and a second bracket at the outer end facing the transfer plate. The first bracket and the second bracket are both L-shaped structures. When the first comb tooth docking frame and the second comb tooth docking frame are flipped from above the transfer plate to the inside of the comb tooth docking groove, the first bracket and the second bracket are flipped and abut against the bottom of the transfer plate.

[0013] Furthermore, two symmetrically distributed limiting frames are fixed at the bottom of the transfer plate, and the first comb tooth docking frame and the second comb tooth docking frame are assembled with the limiting frames through the first rotating shaft and the second rotating shaft, respectively.

[0014] Furthermore, each end of the first rotating shaft is equipped with a first linkage gear that can rotate synchronously with it. Directly below each first linkage gear is a second linkage gear that meshes with it. The two second linkage gears are mounted on a limiting frame via the same drive rod. The limiting frame is equipped with a drive motor assembly for driving the drive rod to rotate.

[0015] Furthermore, each end of the second rotating shaft is equipped with a first linkage wheel that can rotate synchronously with it, and a second linkage wheel is provided directly below each of the first linkage wheels. The first linkage wheels and the second linkage wheels are connected by a first synchronous belt, and the two second linkage wheels are mounted on the limit frame by the same synchronous rod.

[0016] Furthermore, the drive rod is equipped with two synchronous rotating wheels 1 that can rotate synchronously with it. The two synchronous rotating wheels 1 are respectively located on the side of the two linkage gears 2 away from the limit frame. The synchronous rod is equipped with two synchronous rotating wheels 2 that can rotate synchronously with it. The two synchronous rotating wheels 2 are respectively located on the side of the two linkage gears 2 away from the limit frame. The synchronous rotating wheels 1 and 2 are connected by a second synchronous belt.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. This invention, through the design of a transfer vehicle, allows for convenient short-distance movement of the oil-free scroll air compressor to the inside of the lifting frame, facilitating subsequent lifting operations. Compared to manual handling, this effectively reduces labor intensity and improves safety. During the transfer process, two sets of locking frames can engage and limit the wheels of the oil-free scroll air compressor, preventing accidental displacement and enhancing the stability of the transfer process.

[0019] 2. This invention utilizes a flip-out first comb-tooth docking frame and a second comb-tooth docking frame to smoothly connect the transfer plate to the lifting frame, facilitating subsequent overall lifting operations and preventing the transfer plate from detaching from the lifting frame during hoisting. Furthermore, this docking method prevents the transfer plate from shifting forward / backward or left / right as it moves with the lifting frame, and also enhances the load-bearing strength of the docking point, thereby maintaining the stability of the oil-free scroll air compressor during transportation. Simultaneously, it ensures the structural strength of the docking point, preventing breakage caused by excessive stress in single-point docking methods. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Reference Figure 1The illustrated transport vehicle for lifting an oil-free scroll air compressor includes a transport vehicle 2, a transport plate 1 movably mounted on the transport vehicle 2, and a lifting frame 3 that can connect with the transport plate 1. The lifting frame 3 forms a space that allows the transport vehicle 2 and the transport plate 1 to move in and out simultaneously. In actual use, before the oil-free scroll air compressor is lifted, it can be placed on the surface of the transport plate 1. The transport plate 1 moves synchronously with the transport vehicle 2. After the transport vehicle 2, the transport plate 1, and the mounted oil-free scroll air compressor are synchronously moved into the inner side of the lifting frame 3, they can be lifted. During the lifting operation, the transport plate 1 and the mounted oil-free scroll air compressor must connect with the lifting frame 3 and then be lifted and transferred together to the designated location.

[0035] With the transfer vehicle 2 in place, the oil-free scroll air compressor can be easily moved a short distance to the inside of the hoisting frame 3, facilitating subsequent hoisting operations. Compared to manual handling, this effectively reduces labor intensity and improves safety.

[0036] like Figure 2 , Figure 3 As shown, the transfer plate 1 is equipped with two sets of symmetrically distributed clamping frames 4. Each set of clamping frames 4 consists of two frames, each with an open trapezoidal structure. The two sets of clamping frames 4 can move synchronously in opposite directions to engage or disengage the wheel body of the oil-free scroll air compressor. When the clamping frame 4 engages with the wheel body, it can lock and limit the wheel body of the oil-free scroll air compressor, preventing accidental displacement of the oil-free scroll air compressor during transfer and improving the stability of the transfer process.

[0037] Because the clamping frames 4 all have an open trapezoidal structure, they can accommodate wheels of different sizes during the process of moving and clamping the oil-free scroll air compressor. At the same time, they can prevent the oil-free scroll air compressor from shifting forward, backward, left, or right, thus improving the comprehensiveness of the limit operation.

[0038] like Figure 2 , Figure 3 and Figure 11 As shown, the transfer plate 1 is provided with a first comb tooth docking frame 6 and a second comb tooth docking frame 7 on both sides. The hoisting frame 3 is provided with a comb tooth docking groove 31 that can be adapted to the first comb tooth docking frame 6 and the second comb tooth docking frame 7. The first comb tooth docking frame 6 and the second comb tooth docking frame 7 can rotate synchronously in opposite directions. When the transfer car 2 and the transfer plate 1 move into the inner side of the hoisting frame 3, the first comb tooth docking frame 6 and the second comb tooth docking frame 7 are flipped from above the transfer plate 1 to the inner side of the comb tooth docking groove 31. At this time, the first comb tooth docking frame 6 and the second comb tooth docking frame 7 can smoothly dock the transfer plate 1 with the hoisting frame 3, which facilitates the subsequent overall hoisting operation and prevents the transfer plate 1 from detaching from the hoisting frame 3 during the hoisting process.

[0039] The comb-shaped docking method adopted between the first comb tooth docking frame 6, the second comb tooth docking frame 7 and the comb tooth docking groove 31 can prevent the transfer plate 1 from shifting in the front-back and left-right directions during the movement of the hoisting frame 3. It can also improve the bearing strength of the docking position, so that the transfer plate 1 can be hoisted and moved smoothly with the hoisting frame 3, thereby maintaining the stability of the oil-free scroll air compressor during transportation. At the same time, it also ensures the structural strength of the docking position, avoiding the breakage caused by excessive force due to the single-point docking mode.

[0040] Example 2: Figure 4 , Figure 5 As shown, based on Embodiment 1, in order to enable the two sets of card holders 4 to move synchronously, in this invention, each set of card holders 4 is connected by an extension rod 41. The transfer plate 1 is provided with a channel for the two extension rods 41 to move, and the two extension rods 41 extend through the channel to the bottom of the transfer plate 1.

[0041] like Figure 6 As shown, each of the two extension rods 41 is equipped with a guide rack 42 that moves synchronously with it. The two guide racks 42 are diagonally parallel and connected, and the same guide gear 5 is meshed on the inner side of the two guide racks 42. The guide gear 5 is mounted below the transfer plate 1, and an electric push rod 12 is mounted below the transfer plate 1 to drive one of the two guide racks 42 to move. When the electric push rod 12 operates and pushes one of the two guide racks 42 to move, under the meshing transmission of the guide gear 5, the other guide rack 42 will move synchronously in the opposite direction, thereby driving the two extension rods 41 to move towards each other. This achieves the purpose of synchronously clamping the two sets of clamping frames 4 onto the oil-free scroll air compressor wheel body, ensuring the synchronicity of the movement of the two sets of clamping frames 4 and improving the limiting effect.

[0042] like Figure 5 As shown, the bottom of the transfer plate 1 is equipped with two parallel guide rails 11, and two guide racks 42 are slidably assembled with the two guide rails 11 respectively. The guide rails 11 can guide the movement of the guide racks 42, ensure the stability of the guide racks 42 during the movement process, avoid the guide racks 42 from tilting or deviating during the movement, and ensure the smoothness of the meshing transmission.

[0043] Example 3: Due to the limited length and width of the first comb tooth connecting frame 6 and the second comb tooth connecting frame 7, in order to extend their service life during the long-term use of the hoisting structure, such as... Figure 9 and Figure 10As shown in the figure, in this invention, a first bracket 61 and a second bracket 71 are respectively fixed to the outer end of the first comb tooth docking frame 6 and the second comb tooth docking frame 7 facing the transfer plate 1. Both the first bracket 61 and the second bracket 71 have an L-shaped structure. When the first comb tooth docking frame 6 and the second comb tooth docking frame 7 are flipped from above the transfer plate 1 to the inner side of the comb tooth docking groove 31, the first bracket 61 and the second bracket 71 flip and abut against the bottom of the transfer plate 1. Subsequently, during the process of the transfer plate 1 and the oil-free scroll air compressor being lifted and moved along with the lifting frame 3, the first bracket 61 and the second bracket 71 can support the entire transfer plate 1, increasing the overall stress-bearing area, reducing the stress per unit area of ​​the first comb tooth docking frame 6 and the second comb tooth docking frame 7, reducing stress concentration, further improving the structural stability of the docking position, and dispersing the load borne by the first comb tooth docking frame 6 and the second comb tooth docking frame 7. This effectively avoids premature fatigue damage at the docking position and extends the overall service life of the equipment.

[0044] like Figure 8 As shown, two symmetrically distributed limiting frames 13 are fixed to the bottom of the transfer plate 1. The first comb tooth docking frame 6 and the second comb tooth docking frame 7 are assembled with the limiting frames 13 via the first rotating shaft 62 and the second rotating shaft 72, respectively. The limiting frames 13 ensure the stability of the first comb tooth docking frame 6 and the second comb tooth docking frame 7 during installation.

[0045] The first rotating shaft 62 is equipped with a first linkage gear 63 at each end, which can rotate synchronously with it. Below each first linkage gear 63 is a second linkage gear 64 that meshes with it. The two second linkage gears 64 are mounted on a limiting frame 13 via a common drive rod 65. A drive motor assembly 67 for driving the drive rod 65 is mounted on the limiting frame 13. When the drive motor assembly 67 operates and drives the drive rod 65 to rotate, the two second linkage gears 64 rotate synchronously, driving the corresponding first linkage gear 63 to rotate through meshing transmission, thereby driving the first rotating shaft 62 to rotate, realizing the flipping action of the first comb tooth docking frame 6 and the first bracket 61.

[0046] like Figure 8 As shown, the second rotating shaft 72 is equipped with a first rotating wheel 73 at each end, which can rotate synchronously with it. A second rotating wheel 74 is located directly below each first rotating wheel 73. The first rotating wheel 73 and the second rotating wheel 74 are connected by a first synchronous belt 75. The two second rotating wheels 74 are mounted on the limiting frame 13 via the same synchronous rod 76. When the synchronous rod 76 rotates, the first rotating wheel 73 and the second rotating wheel 74 rotate synchronously under the connection of the first synchronous belt 75, thereby driving the second rotating shaft 72 to rotate and causing the second comb tooth docking frame 7 and the second bracket 71 to flip.

[0047] Furthermore, in order to enable the first comb tooth docking frame 6 and the second comb tooth docking frame 7 to simultaneously perform flipping operations in opposite directions, such as... Figure 8 As shown, in this invention, the drive rod 65 is equipped with two synchronous rotating wheels 66 that can rotate synchronously with it. The two synchronous rotating wheels 66 are respectively located on the side of the two linkage gears 64 away from the limit frame 13. The synchronous rod 76 is equipped with two synchronous rotating wheels 77 that can rotate synchronously with it. The two synchronous rotating wheels 77 are respectively located on the side of the two linkage gears 74 away from the limit frame 13. The synchronous rotating wheels 66 and the synchronous rotating wheels 77 are connected by a second synchronous belt 78.

[0048] When the drive rod 65 rotates, it drives the synchronous rotating wheel 77 to rotate synchronously through the first synchronous rotating wheel 66 and the second synchronous belt 78, which in turn drives the synchronous rod 76 to rotate. The synchronous rod 76 drives the two linkage rotating wheels 74 to rotate, and then drives the linkage rotating wheel 73 to rotate through the first synchronous belt 75, which in turn drives the second rotating shaft 72 to rotate. Finally, the first comb tooth docking frame 6 and the second comb tooth docking frame 7 rotate synchronously in opposite directions, ensuring the synchronicity of their rotation and ensuring the smooth implementation of the docking operation.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
