Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0026] In order to prevent the barrels from falling or tipping over during transportation, a clamping device is usually required to fix the barrels during transportation. However, the existing clamping device cannot determine whether the barrels are clamped tightly after clamping them. The operator needs to check the clamping status of the barrels one by one, which takes a lot of time.

[0027] The utility model proposes a clamping device for a material barrel, wherein the barrel mouth of the material barrel extends outward to form a barrel edge, the clamping device comprises a base 1, a column 2, a first elastic member 201 and a position sensor 3, the column 2 is connected to the base 1 and extends vertically, the column 2 is connected to a clamp 21 through a connecting rod structure 20, the clamp 21 can be raised and lowered between a first position and a second position along the column 2, the clamp 21 is used to clamp or release the barrel edge, and the clamp 21 can be lowered from the first position to the second position along the column 2 under the action of the gravity of the material barrel when the barrel edge is clamped; the two ends of the first elastic member 201 are respectively connected to the column 2 and the connecting rod structure 20, and the first elastic member 201 is used to pull the clamp 21 in the second position to the first position through the connecting rod structure 20 when the clamp 21 releases the barrel edge; the position sensor 3 is installed on the column 2, and the position sensor 3 is used to sense the clamp 21 when the clamp 21 is in the second position.

[0028] See also Figure 1 The base 1 provides support for the column 2 to ensure that the clamping device remains stable when the clamp 21 clamps the barrel. The column 2 is enclosed inside to form a placement space, and a sidewall on one side of the column 2 is provided with an avoidance groove. The connecting rod structure 20 passes through the avoidance groove and is hinged to the clamp 21 outside the placement space. When the clamp 21 clamps the rim of the barrel, the clamp 21 drops from the first position to the second position under the action of the barrel's own weight, and drives the connecting rod structure 20 to overcome the pulling force of the first elastic member 201 and move downward. When the clamp 21 drops to the second position, the position sensor 3 can sense the position of the clamp 21 to confirm that the clamp 21 is in a clamped state; when the clamp 21 does not clamp the rim of the barrel, the connecting rod structure 20 moves upward under the pulling force of the first elastic member 201 and pulls the clamp 21 up, so that the clamp 21 gradually moves away from the position sensor 3, so as to confirm that the clamp 21 is in a relaxed state through the position sensor 3; when the barrel is removed from the clamping device, the first elastic member 201 can lift the clamp 21 to the first position through the connecting rod structure 20 to reset the clamp 21.

[0029] The barrel clamping device proposed by the utility model is provided with a position sensor 3 below the clamp 21, and utilizes the characteristic that the clamp 21 can drop to the second position under the weight of the barrel when clamping the barrel, and senses the position of the clamp 21 through the position sensor 3 to confirm whether the clamp 21 is in a clamping state, thereby realizing automatic inspection of the clamping state of the clamping device, without manual inspection, and saving inspection time. By providing a first elastic member 201 and a connecting rod structure 20 connected to the clamp 21, the clamp 21 can automatically reset when the barrel is removed from the clamping device, so as to facilitate the reuse of the clamping device.

[0030] In one embodiment, the connecting rod structure 20 includes two connecting rod assemblies 202, which are arranged along the vertical interval and are respectively hinged to the upper and lower sides of the clamp 21. The two ends of the first elastic member 201 are respectively connected to the column 2 and any one of the connecting rod assemblies 202. The first elastic member 201 is used to pull the clamp 21 in the second position to the first position through the connecting rod assembly 202 connected thereto when the clamp 21 releases the barrel edge.

[0031] It can be understood that the two connecting rod assemblies 202 are respectively hinged on the upper and lower sides of the clamp 21. When the clamp 21 is lifted or lowered, the two connecting rod assemblies 202 swing with the movement of the clamp 21. The first elastic member 201 is connected to any one of the connecting rod assemblies 202. When the first elastic member 201 drives the connecting rod assembly 202 connected thereto to swing upward, the connecting rod assembly 202 drives the clamp 21 to move upward, and the clamp 21 drives the other connecting rod assembly 202 to swing synchronously. The two connecting rod assemblies 202 are respectively supported on the upper and lower sides of the clamp 21, so that the clamp 21 remains stable during the lifting process.

[0032] In one embodiment, the connecting rod assembly 202 includes two connecting rods 2020 and a transition rod 2021 connected between the two connecting rods 2020. The two connecting rods 2020 are respectively hinged on both sides of the clamp 21 along the horizontal direction. One of the transition rods 2021 in the two connecting rod assemblies 202 is used to connect to the first elastic member 201.

[0033] Specifically, both ends of each connecting rod 2020 are hinged to the clamp 21 and the column 2, respectively, and the same ends of the two connecting rods 2020 are connected by a transition rod 2021. The first elastic member 201 is connected to the middle of the transition rod 2021, and the first elastic member 201 applies a pulling force to the transition rod 2021 to drive the two connecting rods 2020 to swing, so that the pulling force of the first elastic member 201 is evenly distributed to the two connecting rods 2020, so that the two connecting rods 2020 drive the clamp 21 to reset more stably.

[0034] In one embodiment, a plurality of pairs of mounting holes 23 are respectively provided on both sides of the column 2 along the horizontal direction, and any pair of mounting holes 23 is used for allowing a mounting rod 22 to pass through so that the mounting rod 22 is supported on the column 2, and the transition rod 2021 connected to the first elastic member 201 is hinged to the mounting rod 22 through an adapter block.

[0035] See also Figure 2 , two mounting holes 23 in a pair of mounting holes 23 are respectively opened on the side walls of the column 2, and the two mounting holes 23 are located at the same horizontal height, so that the mounting rod 22 can be inserted into the pair of mounting holes 23 and remain horizontal, so that the adapter block can rotate smoothly relative to the mounting rod 22. By inserting the mounting rod 22 into the mounting holes 23 at different heights, the height of the connecting rod structure 20 and the tension of the first elastic member 201 can be adjusted, so that the clamp 21 can drop to the second position under the weight of the barrel when clamping barrels of different weights, so that the clamp 21 can adapt to barrels of different weights and is easy to adjust.

[0036] In one embodiment, the clamp 21 includes a shell 210, a clamp 211, a second elastic member 212 and a transmission assembly 9, the connecting rod assembly 202 is connected to both sides of the shell 210, and a vertically extending slide groove 2100 is formed on the shell 210, the clamp 211 includes a first jaw 2110 and a second jaw 2111 spaced apart from each other, the first jaw 2110 and the second jaw 2111 can both slide up and down along the slide groove 2100, and the transmission assembly 9 is connected between the first jaw 2110 and the second jaw 2111; the second jaw 2111 is used to place the barrel edge of the barrel and can slide downward under the action of the gravity of the barrel, and the transmission assembly 9 is used to drive the first jaw 2110 to slide downward when the second jaw 2111 slides downward until it cooperates with the second jaw 2111 to clamp the barrel edge; the second elastic member 212 is used to drive the first jaw 2110 to slide upward when the barrel is released, and drive the second jaw 2111 to slide upward through the transmission assembly 9.

[0037] See also Figure 3, the first jaw 2110 is located above the second jaw 2111, and the first jaw 2110 and the second jaw 2111 are connected by a transmission assembly 9 provided in the housing 210. When the clamp 21 proposed by the utility model is used to clamp a barrel, the barrel edge of the barrel is placed on the second jaw 2111, and the second jaw 2111 slides downward along the slide groove 2100 under the action of the barrel's own weight. The second jaw 2111 drives the first jaw 2110 to slide downward along the slide groove 2100 through the transmission assembly 9, and the first jaw 2110 has a larger displacement than the second jaw 2111, so that the first jaw 2110 and the second jaw 2111 clamp the barrel edge from the upper and lower sides of the barrel edge respectively, and the clamp 21 drops to the second position under the action of the barrel's own weight to pass. The clamping state of the first jaw 2110 and the second jaw 2111 is confirmed by the position sensor 3; when the barrel needs to be removed from the clamp 21, the barrel is lifted so that the second jaw 2111 no longer bears the weight of the barrel edge, and the first jaw 2110 slides upward under the pulling force of the second elastic member 212, and the second jaw 2111 is driven to slide upward along the slide groove 2100 by the transmission assembly 9, and the first jaw 2110 has a larger displacement than the second jaw 2111, so that the first jaw 2110 gradually moves away from the second jaw 2111 to loosen the barrel edge. The clamp 21 proposed by the utility model is easy to operate when clamping and removing the barrel, and the first jaw 2110 and the second jaw 2111 can be automatically reset, which is convenient for repeated clamping.

[0038] In one embodiment, the transmission assembly 9 includes a first transmission wheel 91, a second transmission wheel 92, a first transmission belt 93 and a second transmission belt 94. The first transmission wheel 91 and the second transmission wheel 92 are both rotatably disposed in the housing 210, and the first transmission wheel 91 and the second transmission wheel 92 rotate coaxially. The circumference of the first transmission wheel 91 is greater than the circumference of the second transmission wheel 92. The first transmission belt 93 is connected between the first transmission wheel 91 and the first jaw 2110, and the second transmission belt 94 is connected between the second transmission wheel 92 and the second jaw 2111.

[0039] See also Figure 4 , the first transmission wheel 91 and the second transmission wheel 92 can rotate coaxially. When the second jaw 2111 slides downward under the weight of the barrel, the second transmission belt 94 drives the second transmission wheel 92 and the first transmission wheel 91 to rotate, and the first transmission wheel 91 drives the first jaw 2110 to slide downward through the first transmission belt 93; the circumference of the first transmission wheel 91 is greater than the circumference of the second transmission wheel 92, so that the first jaw 2110 has a larger displacement relative to the second jaw 2111, ensuring that when the second jaw 2111 slides downward to the bottom of the slide groove 2100, the first jaw 2110 can slide above the barrel edge and clamp the barrel edge together with the second jaw 2111.

[0040] In one embodiment, the clamping device further includes an alarm 4, which is mounted on the top of the column 2. The side wall of the column 2 is provided with a threading hole for the wire harness to pass through.

[0041] It can be understood that the position sensor 3 and the alarm 4 are both electrically connected to the external processor. The external processor can receive the position information of the clamp 21 transmitted by the position sensor 3, and control the alarm 4 to issue an alarm based on the position information, so as to promptly remind the operator when the clamp 21 fails to clamp the barrel.

[0042] In one embodiment, the bottom of the column 2 is connected with an arc-shaped clamp 5 for clamping with the side wall of the bucket, and the arc-shaped clamp 5 is located below the clamp 21 .

[0043] It can be explained that the barrel edge is formed at the top of the barrel. When the clamp 21 clamps the barrel edge, the side wall of the barrel is suspended in the air. The side wall of the barrel is clamped and fixed by setting an arc-shaped clamp 5, which can keep the barrel fixed, thereby enhancing the stability of the barrel during clamping and transportation.

[0044] In one embodiment, the bottom end of the column 2 is connected to one side of the base 1, and the top end of the column 2 is connected to the other side of the base 1 through a diagonal brace 6. The diagonal brace 6 is connected to the side of the column 2 away from the clamp 21, so that the clamp 21 remains stable when clamping the barrel, effectively preventing the clamp 21 from tilting.

[0045] The utility model also proposes a barrel transportation device, which includes a mounting seat and a clamping device. The specific structure of the clamping device refers to the above embodiment. Since the barrel transportation device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the clamping device is supported on the transportation device through the base 1, and the fixed seat 7 is connected to the base 1 through the chain 8. The clamping device can be stably installed on the transportation device, so that the barrel can be clamped by the clamping device during transportation.

[0046] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
