[0040] Reference Figure 1 and Figure 2 , Figure 1 is a perspective view of a handling device according to the present disclosure, Figure 2 1 is a side view of a handling device according to the present disclosure. The present disclosure provides a handling device, which comprises a main frame 10, a lifting assembly 20, a transmission assembly 30, a release and locking mechanism 40 and a clamping assembly 50. The above components or assemblies will be described below with reference to the accompanying drawings.

[0041] Reference Figure 3 , Figure 3 It is a stereoscopic view of the main frame 10 of the handling equipment according to the present disclosure. The frame 10 is formed by a profile. A pedal 101 is connected to the bottom profile of the frame 10. The pedal 101 can be stepped on to cooperate with the transmission assembly 30 and the lifting assembly 20 described later to raise and lower the lifting assembly 20. The right end portion of the frame 10 (the right side in the figure) is provided with an upwardly inclined fixed plate 102, and the fixed plate 102 can be used to place, for example, a material box. The fixed plate can also be replaced with a handle for a cart, or the operator can also directly push the profile itself. The bottom of the frame 10 is provided with wheels for forward and backward movement.

[0042] The following will refer to Figure 4 A lifting assembly 20 according to the present disclosure is described. Figure 4 is a perspective view of a lift assembly 20 according to the present disclosure. Figure 4A fixed plate 103 is shown in the figure, and the fixed plate 103 is fixed to the main frame 10. A guide groove 1030 is provided on one side of the fixed plate 103. The lifting assembly 20 includes a lifting frame 201, and the lifting frame 201 is also formed by a profile. A movable plate 202 is fixed to the lifting frame 201. A protrusion 2020 that cooperates with the guide groove 1030 is provided on the movable plate 202, so that through the cooperation between the guide groove 1030 and the protrusion 2020, the lifting assembly 20 can move up and down relative to the main frame 10. In addition, the lifting assembly 20 also includes a lifting platform 203, and the lifting platform 203 is fixed to the lifting frame 201 and can be used to place materials such as water tanks. Refer to Figure 1 and Figure 2 The lifting assembly 20 is arranged on the left side of the main frame 10.

[0043] The following will refer to Figure 1 and Figure 2 The transmission assembly 30 of the present disclosure is described. The transmission assembly 30 includes a transmission member 301. The transmission member 301 is connected to the lifting frame 201 so that when power is input, the lifting frame 201 is driven to rise and fall relative to the main frame 10. In this embodiment, the transmission member 301 is configured as a chain, and power transmission is performed by engaging with a gear. The purpose of such a configuration is related to the subsequent release and locking mechanism 40, which will be described later.

[0044] The transmission assembly 30 further includes a first gear 302 fixed to the lifting frame 201 and a second gear 303 fixed to the main frame 10, one end of the chain is fixed to the main frame 10, the first gear 302 is engaged with the chain in the form of a movable pulley, and the second gear 303 is engaged with the chain in the form of a fixed pulley. Specifically, the left end of the chain is fixedly connected to the fixed plate 103, and the right end is fixedly connected to the fixed portion 1010 on the pedal 101.

[0045] like Figure 2 As described above, since the first gear 302 is configured as a movable pulley and the second gear 303 is configured as a fixed pulley, the chain is wound around the first gear 302 and the second gear 303. By stepping on the pedal 101, the pedal 101 starts to pull the chain, so that the chain drives the first gear 302 as a movable pulley to move upward, thereby driving the lifting frame 201 to move upward, thereby achieving the lifting of the lifting frame 201. In addition, when the pedal 101 is released, the lifting frame 201 will not fall due to gravity, which is achieved by the release and locking mechanism 40.

[0046] As mentioned above, the chain and the first gear 302 and the second gear 303 form a pulley block. Therefore, it should be understood that the pulley block is not limited to the above form. For example, the transmission assembly 30 may also include additional movable pulleys and fixed pulleys in the form of gears. Figure 2 The transmission assembly 30 further comprises a third gear 304, and the release and locking mechanism 40 described below acts on the third gear 304. The third gear 304 and the second gear 303 are both fixed to the upper profile of the main frame 10.

[0047] The following will refer to Figure 5-Figure 7 A release and locking mechanism 40 for a lift assembly 20 according to the present disclosure is described. Figure 5 is a perspective view of a release and locking mechanism 40 for a lift assembly 20 according to the present disclosure. Figure 6 is a side view of a release and locking mechanism 40 for a lift assembly 20 according to the present disclosure. Figure 7 is a side view of a release and locking mechanism 40 for a lift assembly 20 according to the present disclosure.

[0048] like Figure 6 The release and lock mechanism 40 includes a ratchet pawl mechanism, and the ratchet pawl mechanism includes a pawl 401 and a ratchet 405. The rotation axis of the ratchet 405 is fixed to the rotation axis of the second gear 303 and rotates synchronously with the second gear 303. Figure 6 The pawl 401 is shown in an engaged position with the ratchet wheel 405. Figure 6 As described above, when the second gear 303 rotates in the clockwise direction in the figure, the ratchet 405 also rotates in the clockwise direction, and the pawl 401 does not prevent the rotation of the second gear 303. When the second gear 303 rotates in the counterclockwise direction in the figure, the ratchet 405 also rotates in the counterclockwise direction, and the pawl 401 prevents the rotation of the second gear 303. Therefore, when the pedal 101 is stepped on, the chain drives the second gear 303 to rotate clockwise, and when the pedal 101 is released, the pawl 401 prevents the rotation of the second gear 303, so the second gear 303 will not rotate counterclockwise due to the deadweight of the lifting frame 201 pulling the chain. Therefore, the position locking of the lifting assembly 20 after lifting can be achieved with a simple structure.

[0049] The release of the position of the lifting assembly 20 after lifting will be described below. The release and locking mechanism 40 includes a release member 402, and the release member 402 is configured to drive the pawl 401 to rotate to a release position away from the ratchet wheel 405. Figure 7As shown, the release and locking mechanism 40 includes a connecting rod 403 and a rotating member 404, wherein the connecting rod 403 is fixedly connected to the pawl 401 and the rotating member 404, and the rotating member 404 and the release member 402 are both provided with teeth that engage with each other. When the release member 402 moves, the rotating member 404 is driven to rotate by the engagement of the teeth, thereby driving the pawl 401 to rotate to the release position through the connecting rod 403.

[0050] In this embodiment, the release member 401 is configured as a pull rod extending through the main frame 10, and the pull rod is configured to drive the pawl 401 to rotate to the release position when being pulled upward, and after being released, it falls due to gravity and drives the pawl 401 to rotate back to the engagement position with the ratchet 405. It should be understood that the release member 401 can also take other forms as long as the pawl 401 can be taken away from the ratchet 405. For example, the release member 401 can be configured as a lever fixed to the pawl 401, and the pawl 401 is rotated away from the ratchet 405 by toggling the lever. In this embodiment, the rotation axis of the ratchet 405 is coaxially fixed to the rotation axis of the second gear 303 (that is, they share a rotation axis), but it should be understood that the rotation axis of the ratchet 405 can be coaxially fixed to the rotation axis of a fixed gear other than the second gear 303 that serves as a movable pulley, and can still play the same role.

[0051] The following will refer to Figure 8 and Fig. 9 A clamp assembly 50 of the present disclosure is described. Figure 8 is a front view of a clamp assembly 50 according to the present disclosure. Fig. 9 2 is a perspective view of a clamping assembly 50 according to the present disclosure. The clamping assembly 50 is connected to the lifting assembly 20 and is movable relative to the lifting assembly 20 between a clamping position and a releasing position.

[0052] The clamping assembly 50 includes a clamping member frame 501, and the clamping member frame 501 is fixed to the lifting frame 201. The clamping assembly 50 also includes a clamping member 502, and the clamping member 502 can move up and down relative to the clamping member frame 501. This is achieved by the swing arm 503 of the clamping assembly 50. The swing arm 503 can rotate around the rotation axis and the rotation axis remains fixed relative to the clamping member frame 502. The upper end of the swing arm 503 abuts against the bottom rod 5020 of the clamping member frame 501. When the swing arm 503 rotates counterclockwise in the figure, one end of the swing arm 503 pushes the clamping member 502 to rise. In this embodiment, a recess 5021 is provided on the bottom rod 5020 of the clamping part 501. One end of the swing arm 503 is provided with a rolling member 5031, and the rolling member 5031 rolls and pushes against the bottom rod 5020 of the clamping part 501. As the swing arm 503 rotates, one end of the swing arm 503 can be engaged into the recess 5021 so that the clamping assembly is kept in the released position. At this time, the swing arm 503 is in a substantially vertical position, so the gravity of the clamping member 502 does not cause the swing arm 503 to rotate further. When the clamping member 502 needs to be lowered for clamping, the clamping member 502 can be rotated clockwise so that the rolling member 5031 of the swing arm 503 is disengaged from the recess 5021. In this embodiment, the clamping assembly 50 is further provided with a rocker 504, which is connected to the swing arm 503 so that the swing arm can be easily shaken.

[0053] As described above, the present disclosure provides a transport device, which can not only conveniently raise and lower the transport platform to adapt to the items to be transported at different heights, but also achieve a stable clamping of the items to be transported through the clamping assembly. The transport device disclosed in the present disclosure is simple to operate, and not only achieves the effect of the pulley block through the cooperation of the gears and chains, but also realizes the automatic locking function with the ratchet and pawl mechanism. Such a configuration allows the transport platform to be raised by stepping on the foot pedal, and the height of the transport platform is locked after raising. When the transport platform needs to be lowered, it only needs to pull the pull rod to release the ratchet and pawl mechanism. For the clamping and release of the clamping assembly, it is only necessary to rotate the swing arm.

The various embodiments of this utility model may be combined arbitrarily without departing from the spirit and scope of the present disclosure.
