Description

Technical Field

[0001] The present application relates to the technical field of gate lifting, and in particular to a single-cylinder gate lifting mechanism. Background Art

[0002] The split-type domestic waste compressor is divided into two parts: a compression main unit and a garbage bin. The compression main unit presses the garbage in the compression chamber of the compression main unit into the garbage bin through horizontal direct pressure technology. Before the compressor operates, the gate of the compressor needs to be lifted by a lifting mechanism to connect the compression chamber of the compression main unit with the garbage bin.

[0003] In the prior art, the lifting mechanism mainly includes a lifting frame, a locking hook, a double oil cylinder and a frame. The lifting frame is raised and lowered on the frame by the double oil cylinder. The locking hook is installed on the lifting frame, and the locking hook will be inserted into the locking hook slot of the gate. After the locking hook is inserted into the locking hook slot, the lifting frame can lift the gate. Slide blocks are installed on the left and right sides of the lifting frame. The slide blocks are slidably connected in the slide groove of the frame. The slide groove plays a guiding role in the lifting process of the lifting frame. When the lifting frame fails, it is necessary to first disassemble the frame and the oil cylinder and then take the lifting frame out of the frame for maintenance. That is, the entire lifting mechanism needs to be dismantled before maintenance, which makes the maintenance process very troublesome.

[0004] In view of the above problems, the present application proposes a single-cylinder gate lifting mechanism. Summary of the invention

[0005] The embodiment of the present application provides a single-cylinder gate lifting mechanism to solve the problem of troublesome maintenance of the lifting frame in the related art.

[0010] Two guide rods are detachably arranged in the frame, and the two guide rods are respectively arranged on both sides of the oil cylinder, and the guide rods pass through the lifting frame.

[0011] In some embodiments, a guide structure is provided on the frame, and the guide structure includes a connecting plate and a guide plate;

[0012] There are two guide plates, a connecting plate is connected to the frame, two guide plates are respectively connected to the connecting plates, the two connecting plates are arranged opposite to each other, and the two connecting plates and the guide plates form a guide channel for the gate to pass through.

[0014] The extension piece is connected to the connecting plate and the guide plate respectively. There is a guide channel in the extension piece for the gate to enter the guide channel. There is an entrance and an exit on the guide channel. The exit is located at one end of the guide channel. The entrance and the exit are arranged opposite to each other, and the horizontal area of ​​the entrance is larger than the horizontal area of ​​the exit.

[0015] In some embodiments, there are two guide structures, which are arranged opposite to each other. When the gate is lifted, the gate passes through two guide channels at the same time.

[0016] In some embodiments, two fixing structures are provided on the lifting frame;

[0017] The fixed structure includes a lock hook, a base, a baffle, and a limit block;

[0018] The base is installed at one end of the lifting frame, and the lock hook is rotatably set at the bottom

[0019] Inside the seat, the baffle is connected to the base, and the limit block is installed on the lock hook;

When the lifting frame needs to be removed from the frame for maintenance, it is only necessary to separate the cylinder from the lifting frame and then pull the guide rod from the frame. Therefore, compared with the traditional maintenance of the lifting frame, which requires disassembly of the entire lifting mechanism, the present application only requires disassembly of the cylinder and the guide rod, and the lifting frame will naturally detach and can be repaired.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The embodiment of the present application provides a single-cylinder gate lifting mechanism, which can solve the problem of troublesome maintenance of the lifting frame in the related art.

[0038] See also Figures 1 to 4A single-cylinder two-gate lifting mechanism comprises: a frame 1, a cylinder 2, a lifting frame 3 and two guide rods 4, the cylinder 2 is detachably mounted on the top of the frame 1, the lifting frame 3 is located in the frame 1, the telescopic end of the cylinder 2 is detachably connected to the lifting frame 3, the guide rod 4 is detachably arranged in the frame 1, the two guide rods 4 are respectively arranged on both sides of the cylinder 2, and the guide rod 4 passes through the lifting frame 3;

[0039] The frame 1 is a rectangular parallelepiped frame 1, and the oil cylinder 2 and the guide rod 4 are installed on the same side of the frame 1 by bolts. The number of oil cylinders 2 is one to avoid the synchronization problem of the double oil cylinders 2. A corresponding through hole is opened on one side of the frame 1 where the oil cylinder 2 and the guide rod 4 are installed. The telescopic end of the oil cylinder 2 and the guide rod 4 pass through the through hole, and the telescopic direction of the telescopic end of the oil cylinder 2 is the same as the length direction of the guide rod 4 after installation. The telescopic end of the oil cylinder 2 and the guide rod 4 are fixed by a latch;

[0040] The lifting frame 3 is lifted and lowered on the frame 1 by the oil cylinder 2, and the guide rod 4 plays a guiding role when the lifting frame 3 is lifted and lowered. At the same time, the two guide rods 4 are located on both sides of the oil cylinder 2 to prevent the lifting frame 3 from shaking on the other side when the lifting frame 3 is lifted;

[0041] When the lifting frame 3 needs to be disassembled for maintenance, the bolts fixing the guide rod 4 are first removed, and then the guide rod 4 is pulled out from the frame 1. At this time, the lifting frame 3 is only connected to the telescopic end of the cylinder 2. Finally, the pin connecting the telescopic end of the cylinder 2 and the lifting frame 3 is pulled out, and the lifting frame 3 is completely disassembled. Compared with the traditional method of disassembling the entire lifting mechanism, the process of disassembling the lifting frame 3 in this application is simpler and more convenient.

[0042] Specifically, in this example, a guide structure 5 is provided on the frame 1, and the guide structure 5 includes a connecting plate 51 and a guide plate 52;

[0043] There are two guide plates 52, the connecting plate 51 is connected to the frame 1, the two guide plates 52 are respectively connected to the connecting plates 51, the two connecting plates 51 are arranged opposite to each other, and the two connecting plates 51 and the guide plates 52 form a guide channel for the gate to pass through;

[0044] When the lifting frame 3 is lowered to a certain height by the cylinder 2, the locking hook 61 will be inserted into the locking hook slot of the gate. At this time, the cylinder 2 will lift the lifting frame 3, and the locking hook 61 on the lifting frame 3 will drive the gate to rise at the same time. In order to ensure that the gate will not easily break away from the locking hook 61, during the rising process of the gate, the gate will enter the guide channel to limit the activity area of ​​the gate, so that the gate can only rise vertically along the guide channel, thereby increasing the stability of the entire device.

[0045] More specifically, in this embodiment, the guide structure 5 further includes an extension member 53;

[0046] The extension piece 53 is connected to the connecting plate 51 and the guide plate 52 respectively. A guide channel for the gate to enter the guide channel is provided in the extension piece. The guide channel has an entrance and an exit. The exit is located at one end of the guide channel. The entrance and the exit are arranged opposite to each other. The horizontal area of ​​the entrance is larger than the horizontal area of ​​the exit.

[0047] The extension piece 53 is in the shape of a non-closed trumpet as a whole. Since the gate is hung on the lifting frame 3 by inserting the locking hook 61 into the locking hook groove, the gate is not fixedly connected. Therefore, in actual situations, there will be slight changes in the position of the gate when it is lifted by the lifting frame 3, but the guide channel will not be adjusted according to these slight changes. In order to avoid the gate being unable to enter the guide channel after being lifted, an extension piece 53 is added to the guide channel to guide the gate into the guide channel. That is, when the gate position changes slightly, the gate will hit the inner wall of the extension piece 53. As the gate is lifted, the gate slides along the inner wall of the extension piece 53 to the guide channel.

[0048] Furthermore, in this embodiment, the number of the guide structures 5 is two, and the two guide structures 5 are arranged opposite to each other. When the gate is lifted, the gate passes through two guide channels at the same time;

[0049] In order to fully limit the activity area of ​​the gate and use as little material as possible, the present application is achieved by limiting the activity range on both sides of the gate, that is, both sides of the gate will enter the guide channel at the same time during the rising process of the gate. In these two guide channels, the gate can only be lifted and lowered along the length direction of the guide channel. The length direction of the guide channel is consistent with the lifting direction of the lifting frame 3. The specific situation of the gate in actual conditions is that the gate is lifted and lowered vertically in the guide channel.

[0050] Furthermore, in this embodiment, two fixing structures 6 are provided on the lifting frame 3;

[0051] The fixing structure 6 includes a locking hook 61, a base 62, a baffle 63, and a limiting block 64;

[0052] The base 62 is installed at one end of the lifting frame 3, the lock hook 61 is rotatably arranged in the base, the baffle 63 is connected to the base 62, and the limit block 64 is installed on the lock hook 61;

[0053] The lock hook 61 has a fixed position. When the lock hook 61 is at the fixed position, the limit block 64 is close to the baffle 63, and the lock hook 61 remains horizontal.

[0054] Bases 62 are respectively installed at both ends of the lifting frame 3, and two corresponding locking hook grooves are provided on the gate. The locking hook 61 is rotatably connected to the base 62. As shown in the figure, when the locking hook 61 is rotatably installed on the lifting frame 3, the part of the locking hook 61 inserted into the locking hook groove will rotate downward under the influence of gravity. In the process of the locking hook 61 rotating downward under the influence of gravity, the limit block 64 will approach the baffle 63. When the limit block 64 supports the baffle 63, the locking hook 61 remains horizontal and the locking hook 61 is stationary. After the locking hook 61 is inserted into the locking hook groove of the gate, the limit block 64 will also limit the rotation of the locking hook 61, so that the gate can be hung on the locking hook 61 and then lifted by the lifting frame 3.

[0055] Preferably, in this embodiment, the fixing structure 6 further includes a torsion spring 65;

[0056] The two ends of the torsion spring 65 are respectively connected to the lock hook 61 and the baffle 63;

[0057] In actual use, the gate is located below the present application, and the lock hook 61 will touch the gate when it descends. At this time, the gate squeezes the lock hook 61 to flip upward, and the torsion spring 65 is tightened. When the lock hook 61 moves to the same height as the lock hook slot of the gate, the torsion spring 65 pops the lock hook 61 downward, so that the lock hook 61 is inserted into the lock hook slot. In this process, the torsion spring 65 can prevent the lock hook 61 from being unable to be inserted into the lock hook slot or being inserted slowly when it moves to the same height as the lock hook slot.

[0058] In a preferred embodiment, a sensing structure 7 is mounted on the frame 1;

[0059] The sensing structure 7 includes a first sensing switch 71, a second sensing switch 72 and a third sensing switch 73;

[0060] The first induction switch 71 is used to prompt that the lifting frame 3 is in the lowest position;

[0061] The second induction switch 72 is used to indicate that the gate has been lifted;

[0062] The third induction switch 73 is used to prompt that the lifting frame 3 is in the highest position;

[0063] The positions of the first induction switch 71, the second induction switch 72 and the third induction switch 73 are shown in the figure;

[0064] When the lifting frame 3 moves to the position of the first induction switch 71, the lock hook 61 is at the same height as the lock hook slot. At this time, the lock hook 61 is inserted into the lock hook slot, that is, when the first induction switch 71 senses the lifting frame 3, the gate has been hung on the lifting frame 3, and the gate can be lifted by the cylinder 2;

[0065] When the gate is sensed by the second sensing switch 72, the gate has entered the guide channel;

[0066] When the lifting frame 3 is sensed by the third sensing switch 73, if the gate is hung on the lifting frame 3, it means that the lifting frame 3 has risen to the highest point. At this time, the gate has been completely lifted, and the compression host and the garbage bin are connected. That is, when the second sensing switch 72 and the third sensing switch 73 simultaneously sense the corresponding devices, it can be said that the gate is lifted into place.

[0067] The first induction switch 71 serves to remind the lifting frame 3 that the lock hook 61 has been inserted into the lock hook slot, and the oil cylinder 2 can be lifted;

[0068] The second induction switch 72 needs to be used in conjunction with the third induction switch 73. When the second induction switch 72 and the third induction switch 73 simultaneously sense the corresponding device, it is prompted that the lifting frame 3 no longer needs to be lifted and the gate has been lifted into place.

[0069] Here’s how this application works:

[0070] During the implementation, the lifting frame 3 is controlled to rise and fall by the oil cylinder 2. When the first induction switch 71 senses the lifting frame 3, the lock hook 61 on the lifting frame 3 is inserted into the lock hook slot. At this time, the oil cylinder 2 drives the lifting frame 3 and the gate to rise. During the lifting process, the gate will enter the guide channel. When the second induction switch 72 and the third induction switch 73 simultaneously sense the corresponding devices, the gate is lifted into place, and the compression host and the garbage bin are connected.

[0071] When the lifting frame 3 needs to be disassembled, it is only necessary to first remove the bolts fixing the guide rod 4, and then pull the guide rod 4 out of the frame 1. At this time, the lifting frame 3 is only connected to the telescopic end of the cylinder 2. Finally, the pin connecting the telescopic end of the cylinder 2 and the lifting frame 3 is pulled out, and the lifting frame 3 is completely disassembled. Compared with the traditional method of disassembling the entire lifting mechanism, the process of disassembling the lifting frame 3 in this application is simpler and more convenient.
