[0027] Please refer to Figures 1 to 3 , an acid barrel transfer device shown in an embodiment of the present application. The acid barrel transfer device includes a push cart frame body 10, a push handle assembly 40, a protection assembly 20, and a support assembly 30. A walking wheel 11 is provided at the bottom of the push cart frame body 10, and the push handle assembly 40 is provided at the top of the push cart frame body 10 to facilitate the staff to push or pull the acid barrel transfer device.

[0028] The protective component 20 is arranged on the top of the trolley frame body 10. The protective component 20 includes a guardrail structure and a hanging structure 23. The guardrail structure includes a U-shaped fixed guardrail 21 and a movable railing 22 arranged at the opening of the U-shaped fixed guardrail 21. A receiving space for accommodating an acid barrel is formed inside the U-shaped fixed guardrail 21. The movable railing 22 is used to open or close the opening of the U-shaped fixed guardrail 21. The hanging structure 23 is arranged at one end of the U-shaped fixed guardrail 21 away from the opening, and the hanging structure 23 is used to lock or unlock the acid barrel.

[0029] The support component 30 is arranged on the top of the trolley frame body 10 and inside the U-shaped fixed guardrail 21. The support component 30 is configured to be rotatable to drive the acid barrel to enter or exit from the opening of the U-shaped fixed guardrail 21. The height of the support component 30 is the same as that of the production conveyor line, so that during the transfer of the acid barrel, the staff can dock the acid barrel transfer device with the production conveyor line to receive the acid barrel. When transferring the acid barrel to the production conveyor line, the acid barrel can also be moved towards the production conveyor line by pushing, so as to be transferred onto the production conveyor line. The transfer process is simple, avoiding laborious operations such as lifting and lowering the acid barrel. Moreover, the transfer process is relatively gentle, and it can also avoid the shaking of the chemicals in the acid barrel.

[0030] In one embodiment, the support component 30 includes a fixed frame and a plurality of rollers arranged inside the fixed frame. The plurality of rollers are arranged at intervals in sequence from the tail of the U-shaped fixed guardrail 21 towards the opening direction. The fixed frame includes a bottom plate and three groups of support bars arranged at intervals on the bottom plate. Both ends of the roller are rotatably connected to two support bars respectively. In this way, the staff can make the roller rotate by itself by pushing the acid barrel, so as to make the acid barrel move horizontally. It is true that in other embodiments, a chain can also be arranged to connect the rollers in series, and a motor can be arranged to drive one of the rollers to rotate, so as to realize the motor driving the rollers to rotate to drive the acid barrel to move horizontally, further reducing the manual participation and reducing the operation intensity.

[0031] In one embodiment, the hanging structure 23 includes a fixing plate 231, a pair of hooks 232 symmetrically arranged at both ends of the fixing plate 231, and a chain 233 hung on the hooks 232. When the acid barrel moves into the U-shaped fixed guardrail 21 and abuts against the fixing plate 231, one end of the chain 233 is taken off, wound around the acid barrel and then hung on the hook 232 again, so as to lock the acid barrel on the acid barrel transfer device and reduce the risk of the acid barrel falling.

[0032] In one embodiment, an arc groove adapted to the shape of the acid barrel body is formed on the fixing plate 231. The acid barrel is abutted in the arc groove. By setting the arc groove to fit the acid barrel, the fixing effect on the acid barrel is further improved.

[0033] In one embodiment, a support frame 24 is provided on the U-shaped fixed guardrail 21, and the pusher assembly 40 and the fixing plate 231 are fixedly arranged on the top of the support frame 24. By providing the support rod, the pusher assembly 40 and the fixing plate 231 can be fixed at a suitable height to adapt to the staff and the acid barrel, improving the fixing effect on the acid barrel. At the same time, the working comfort of the staff is improved. It should be noted that in other embodiments, the support frame 24 can also be set to be telescopically movable in the vertical direction. In this way, it is convenient to adapt to staff of different heights and acid barrels of different barrel heights.

[0034] In one embodiment, the pusher assembly 40 includes a pair of inclined pull rods that are inclined away from the push frame body 10 from the support frame 24 and a grip rod connected between the inclined pull rods. With such a setting, when the staff pushes and pulls the acid barrel transfer device, sufficient activity space is reserved between the staff and the acid barrel transfer device. At the same time, when the staff pushes and pulls the acid barrel transfer device, it can also prevent one end of the acid barrel transfer device from tilting up and causing the vehicle to overturn.

[0035] In one embodiment, the movable railing 22 is a U-shaped rod. One end of the U-shaped rod is rotatably connected to the top of the U-shaped fixed guardrail 21, and the other end is detachably connected to a locking member provided on the U-shaped fixed guardrail 21. A jack is provided on the U-shaped fixed guardrail 21. The two ends of the U-shaped rod are inserted into the jacks of the U-shaped fixed guardrail 21, and the insertion depths of the two ends are different. A clamping block is provided at the end with a deeper insertion depth, so that the U-shaped rod can move upward by a certain distance, facilitating the separation of the end with a shallower insertion depth from the U-shaped fixed guardrail 21, and thus facilitating the rotation of the U-shaped rod to open or close the opening of the U-shaped fixed guardrail 21. In the closed state, the U-shaped rod abuts against the side wall of the acid barrel. It should be noted that in other embodiments, a locking post can also be provided on the U-shaped fixed guardrail 21, and the U-shaped rod is set as a hollow rod to cooperate with locking or unlocking. Any other locking structure can be used as long as the above effects can be achieved, and no specific limitation is made here.

[0036] In one embodiment, the push frame body 10 further includes a brake assembly 50. The brake assembly 50 includes a foot brake plate provided near one end of the pusher assembly 40 and a brake structure provided on the traveling wheel 11. The foot brake plate is used to drive the brake structure to lock or release the traveling wheel 11. In this way, it is convenient for the staff to step on the foot brake plate to control the brake structure to lock the traveling wheel 11, thereby performing a braking action and improving the controllability of the acid barrel transfer device.

[0037] In one embodiment, the traveling wheel 11 includes a universal wheel 111 provided near one end of the pusher assembly 40 and a directional wheel 112 provided at the end away from the pusher assembly 40. The brake structure is provided on the directional wheel 112. By providing the universal wheel 111 near one end of the pusher assembly 40, it is convenient to perform a turning action. The brake structure is provided on the directional wheel 112, which is convenient for actuating control of the acid barrel transfer device.

[0038] In one embodiment, a triangular mounting plate 113 is provided at the bottom of the carriage frame 10, and the traveling wheels 11 are mounted on the triangular mounting plate 113. By providing the triangular mounting plate, it is convenient to mount the traveling wheels 11, and at the same time, the overall structure is more stable.

[0039] In this application, a U-shaped fixed guardrail and a movable railing are provided on the carriage frame to protect the acid barrel during transportation, and a hanging buckle structure is used to lock the acid barrel, thereby preventing the acid barrel from shaking. A support assembly is provided inside the U-shaped fixed guardrail to support the acid barrel, and the rotation of the support assembly drives the acid barrel to enter or exit from the opening of the U-shaped fixed guardrail, realizing the transportation of the acid barrel by the transportation device itself, reducing the participation of manual labor or handling equipment, reducing the transportation risk, and improving the transportation efficiency.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described.
