Description

Technical Field

[0001] The utility model relates to the technical field of lifting and transporting, in particular to a device for achieving high lifting. Background Art

[0002] Devices that enable high lifts typically refer to mechanical systems capable of moving objects or platforms vertically over significant distances. For example, container forklifts, such as those used for loading and unloading containers, must adapt to the confined space within the container. For example, the maximum height of a container forklift should be less than the container door height minus the thickness of the transition plate and the safe clearance for forklift operation, typically 1 to 1.5 meters. Furthermore, container forklifts should feature free-lift capabilities and convenient alignment to accommodate in-container operations.

[0003] At present, in order to improve the unloading efficiency of containers, telescopic arm forklifts are often used. The lifting cylinder is used to lift the cargo. The height of the whole vehicle must be at a certain height. However, for some work in containers, due to the limited size of the container, if the turning scale of the fork in the container is too large, it cannot meet the requirements of the fork for loading / unloading the container. At the same time, it is very easy for the fork to collide with the container, resulting in damage to the fork or the container, affecting the cargo handling. Utility Model Content

[0004] To solve the above technical problems, the present invention utilizes a tilting cylinder to drive the lower connecting rod and the upper connecting rod to rotate around the telescopic end of the telescopic arm, so that the transfer member maintains a balanced state on the tilting frame. The specific technical solution is as follows:

[0005] A device for achieving high lifting, comprising an adjusting member installed at the telescopic end of a telescopic arm and a transfer member provided on the adjusting member; the adjusting member comprises a lower connecting rod and an upper connecting rod, which are arranged at intervals on the telescopic arm; a tilting frame, which is rotatably arranged on the lower connecting rod and the end of the upper connecting rod away from the telescopic arm, and the transfer member is provided on the tilting frame; and a tilting cylinder, whose two ends are respectively rotatably arranged on the rotating point of the lower connecting rod and the telescopic arm and the end of the upper connecting rod close to the tilting frame; wherein the lower connecting rod, the upper connecting rod, the tilting frame and the telescopic arm form a four-bar linkage, and the telescopic end of the tilting cylinder is extended to lift the transfer member and keep it balanced.

[0006] Preferably, the adjusting member further comprises a coupling plate rotatably provided at the telescopic end of the telescopic arm, and the coupling plate is rotatably connected to the same end of the lower connecting rod and the upper connecting rod.

[0007] Preferably, connecting pieces are fixedly provided at both ends of the upper connecting rod, and the upper connecting rod is rotatably arranged with the tilting frame and the coupling plate through the connecting pieces.

[0008] Preferably, two lower connecting rods are provided and are symmetrically arranged on both sides of the upper connecting rod, and a connecting shaft is provided at the end between the pair of lower connecting rods.

[0009] Preferably, there are two tilting frames, which are symmetrically arranged on both sides of the tilting cylinder. The top of the tilting frame is provided with a slot, and the bottom of the tilting frame is provided with a positioning plate that is plugged into the transfer member.

[0010] Preferably, the transfer member further comprises a transfer frame and a cargo fork fixed to each other, the transfer frame is clamped on the tilting frame, and the telescopic end of the tilting cylinder is extended to raise the cargo fork and keep it balanced.

[0011] Preferably, the transfer member further comprises a transfer frame and a bucket fixed to each other, the transfer frame is clamped on the tilting frame, and the telescopic end of the tilting cylinder is extended to raise the bucket and keep it balanced.

[0012] Preferably, the transfer member further comprises a transfer frame and shovel teeth fixed to each other, the transfer frame is clamped on the tilting frame, and the telescopic end of the tilting cylinder is extended to raise the shovel teeth and maintain balance.

[0013] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0014] The utility model comprises a four-link mechanism consisting of a lower link, an upper link, a tilting frame and a telescopic arm. The tilting cylinder drives the lower link and the upper link to rotate around the telescopic end of the telescopic arm, so that the lower link and the upper link gradually flip upward. The telescopic arm always remains stationary, and only the four-link mechanism moves. The transfer piece is raised and kept balanced, so that the transfer piece is prevented from flipping too much in the container, which makes it impossible for the fork to unload the container and affects the cargo handling.

DETAILED DESCRIPTION

[0025] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are for illustrative purposes only.

[0026] This application is used for stacking and transporting goods in a smaller space. The button of the tilting cylinder is operated to make the tilting cylinder push the connecting rod mechanism to move up or down. During this process, the arm body always remains stationary and the external dimensions do not increase. Only the connecting rod mechanism moves, which can effectively prevent collisions in the space.

[0027] like Figures 1-6 As shown, a device for achieving high lifting, including an adjusting member 30 installed at the telescopic end of the telescopic arm 20 and a transfer member 40 provided on the adjusting member 30; the adjusting member 30 includes a lower connecting rod 301 and an upper connecting rod 303, which are arranged at intervals on the telescopic arm 20; a tilting frame 308, both ends of which are respectively rotatably arranged at the lower connecting rod 301 and the upper connecting rod 303 away from the telescopic arm 20, and the transfer member 40 is arranged on the tilting frame 308; and a tilting cylinder 307, which is rotatably arranged at the rotating point of the lower connecting rod 301 and the telescopic arm 20 and the end of the upper connecting rod 303 close to the tilting frame 308; wherein, the lower connecting rod 301, the upper connecting rod 303, the tilting frame 308 and the telescopic arm 20 form a four-bar mechanism, and the telescopic end of the tilting cylinder 307 is extended to lift the transfer member 40 and maintain balance, that is, the goods on the transfer member 40 always remain in a nearly horizontal state, so that the goods on the transfer member 40 will not fall.

[0028] Among them, the telescopic arm 20 is installed on the vehicle body 10, and the transfer part 40 is used to unload the goods in the container 50. The telescopic arm 20 includes a fixed arm, an inner arm, a lifting cylinder, a fork cylinder, a telescopic cylinder, and a compensation cylinder. Its specific functions are as follows: the fixed arm is the main supporting structure of the telescopic arm 20 forklift, which is fixed on the vehicle body 10 and provides a stable base for the entire telescopic arm 20 system; the inner arm is the telescopic part of the telescopic arm 20 system, which is expanded and contracted by the action of the telescopic cylinder to adjust the working distance; the lifting cylinder is connected between the fixed arm and the transfer part 40, and the tilting cylinder 307 is preferably a cylinder. The oil cylinder controls the vertical lifting and lowering of the transfer piece 40 through the tilting cylinder 307 to carry out cargo loading and unloading operations; the fork oil cylinder is used to control the tilting movement of the transfer piece 40, so that the forklift can adjust the loading and unloading angle of the cargo to adapt to cargo of different shapes and sizes; the telescopic oil cylinder is a key component for controlling the extension and retraction of the inner arm. Through the extension and retraction movement of the telescopic oil cylinder, the length of the telescopic arm 20 can be changed to adapt to the requirements of different working distances; the function of the compensation oil cylinder is to balance and compensate the telescopic arm 20 during the lifting or lowering process of the transfer piece 40, so as to prevent the telescopic arm 20 from excessively tilting or bending due to the load, thereby maintaining the stability of the forklift.

[0029] like Figure 1-Figure 7 As shown, the telescopic end of the tilting cylinder 307 is extended, and the tilting cylinder 307 drives the lower connecting rod 301 and the upper connecting rod 303 to rotate around the telescopic end of the telescopic arm 20, so that the lower connecting rod 301 and the upper connecting rod 303 are gradually flipped upward, thereby raising the height of the transfer piece 40. When the height of the transfer piece 40 is raised, the telescopic arm 20 always remains stationary, and the external dimensions do not increase. Only the four-bar linkage moves, so that the height of the cargo in the container 50 is raised, and the transfer piece 40 and the cargo can be unloaded from the container 50 or other narrow spaces through the telescopic arm 20, which can effectively prevent collisions in the space.

[0030] like Figure 1-Figure 3 and Figure 6 As shown, the adjusting member 30 also includes a coupling plate 309 rotatably arranged at the telescopic end of the telescopic arm 20, and the coupling plate 309 is rotatably connected to the same end of the lower connecting rod 301 and the upper connecting rod 303, wherein the coupling plate 309 is installed at the telescopic end of the telescopic arm 20, and the coupling plate 309 rotates with the upper connecting rod 303 and the lower connecting rod 301, so that the adjusting member 30 forms a whole, which is convenient for maintaining the integrity of the adjusting member 30 after disassembly.

[0031] like Figure 6As shown, both ends of the upper connecting rod 303 are fixed with connecting plates 304, and the upper connecting rod 303 is rotatably arranged with the tilting frame 308 and the coupling plate 309 through the connecting plates 304. The upper connecting rod 303 and the connecting plates 304 can be formed by welding, and the upper connecting rod 303 can also be formed by rolling angle steel. The connecting plates 304 are arc-shaped, which is convenient for connecting the two ends of the upper connecting rod 303 with the tilting frame 308 and the coupling plate 309.

[0032] like Figure 5 、 Figure 8 and Figure 9 As shown, there are two lower connecting rods 301, which are symmetrically arranged on both sides of the upper connecting rod 303. A connecting shaft 302 is provided at the end between the pair of lower connecting rods 301. Among them, one upper connecting rod 303 is provided, and the lower connecting rods 301 are arranged on both sides of the upper connecting rod 303 to facilitate the connection between the telescopic end of the tilting cylinder 307 and the upper connecting rod 303. The pair of lower connecting rods 301 are connected to the upper connecting rod 303 through the coupling plate 309 and the connecting piece 304. The cylinder body of the tilting cylinder 307 The connecting shaft 302 arranged at the coupling plate 309 is rotated, and a connecting plate 305 is fixedly installed on the upper connecting rod 303. The connecting plate 305 is at one end of the upper connecting rod 303 close to the transfer member 40, which increases the torque between the tilting cylinder 307 and the rotating part to reduce the force of the tilting cylinder 307. A positioning shaft 306 is provided between a pair of connecting plates 305 on the upper connecting rod 303, and the telescopic end of the tilting cylinder 307 is rotatably connected to the upper connecting rod 303 through the positioning shaft 306.

[0033] like Figure 4-Figure 6 and Figure 8-Figure 9 As shown, there are two tilting frames 308, which are symmetrically arranged on both sides of the tilting cylinder 307. The top of the tilting frame 308 is provided with a slot, and the bottom end is provided with a positioning plate that is plugged into the transfer member 40. The transfer member 40 can be connected to the tilting frame 308 through the slot, and the bottom end of the transfer member 40 is plugged into the tilting frame 308 through a pin shaft to ensure the quick installation and quick removal effect of the transfer member 40, while also ensuring the stability of the transfer member 40.

[0034] As Example 1 of this application:

[0035] When transporting box-type cargo in a container 50 or a narrow space, the transfer unit 40 also includes a fixed transfer frame 401 and a fork 402. The transfer frame 401 is mounted on the tilting frame 308. The telescopic end of the tilting cylinder 307 is extended to raise the fork 402 and maintain balance. The telescopic arm 20 extends the transfer unit 40 into the container 50 or a narrow space, and the fork 402 extends to the bottom end of the box-type cargo. The telescopic arm 20 does not need to be moved again, and the tilting cylinder 307 drives the four-bar linkage When the fork 402 is lifted up and kept in a nearly horizontal state by the transfer frame 401, it can be lifted up. At this time, the telescopic arm 20 can be pulled out horizontally to ensure that the fork 402 and the box cargo are directly taken out, thereby preventing the fork 402 from turning over too much in the container 50, which may easily cause the fork 402 to collide with the container 50 and cause damage to the fork 402 or the container 50. If the cargo needs to be transported to the container 50 or a small space, only the reverse steps need to be followed.

[0036] As the second embodiment of this application:

[0037] When loading bulk cargo in a container 50 or a narrow space, the transfer unit 40 also includes a fixed transfer frame 401 and a bucket. The transfer frame 401 is mounted on the tilting frame 308, and the telescopic end of the tilting cylinder 307 is extended to raise the bucket and keep it balanced. The telescopic arm 20 extends the transfer unit 40 into the container 50 or the narrow space, and the bucket scoops the bulk cargo in the container 50 or the narrow space, and is driven by the transfer frame 401 to rise while keeping the bucket in a nearly horizontal state. At this time, the telescopic arm 20 can be pulled out horizontally to ensure that the bucket and bulk cargo are directly taken out, avoiding the bucket from tipping too much in the container 50 or the narrow space, causing the bucket to collide with the inner wall of the container 50 or the narrow space, resulting in damage to the bucket or the container 50; if bulk cargo needs to be transported to the container 50 or the narrow space, only the reverse steps need to be followed.

[0038] As the third embodiment of this application:

[0039] In addition to the container 50, when forking hard soil and gravel in a narrow space, the transfer part 40 also includes a fixed transfer frame 401 and shovel teeth. The transfer frame 401 is clamped on the tilting frame 308, and the telescopic end of the tilting cylinder 307 is extended to raise the shovel teeth and maintain balance. Among them, the telescopic arm 20 extends the transfer part 40 into the narrow space, and the bucket forks the soil and gravel in the narrow space, and drives the shovel teeth to rise while maintaining a nearly horizontal state through the transfer frame 401. At this time, the telescopic arm 20 can be pulled out horizontally to ensure that the shovel teeth, soil and gravel are directly taken out.
