Description

Technical Field

[0001] The utility model relates to the technical field of oil drum transport tools, in particular to an oil drum grabbing device. Background Art

[0002] Oil drums are commonly used to store oil and many other liquid chemical raw materials. After the finished liquid material is produced, it is placed in an oil drum to facilitate material transportation. Oil drums are placed side by side in the storage area and then transported to the location of use. Oil drums are typically cylindrical with a rim around the top and are usually made of hard polyester. Forklifts are often used for transportation in businesses. Oil drums typically hold over 200L and cannot be moved by one person. At least two people are required to load them onto a forklift, which is time-consuming, labor-intensive, inefficient, unsafe, and poses a risk of accidental injury. Utility Model Content

[0003] The utility model aims to solve the problem of wasting manpower when transporting oil drums to a forklift by manpower, and provides an oil drum grabbing device which is used in conjunction with a forklift and can grab the oil drum by grabbing the upper edge of the top of the oil drum. The oil drum is moved to the forklift without manpower, which saves manpower, reduces labor intensity and improves transportation efficiency.

[0004] In order to solve the above technical problems, the utility model includes a bracket that can be installed on the fork of a forklift, and the bottom of the bracket is provided with two fork sleeves that can be sleeved on the fork of the forklift. The bracket also includes at least one column arranged away from the forklift, and the upper part of the column is provided with a grabbing assembly for grabbing the oil drum, and the grabbing assembly is arranged on the side of the column away from the forklift. The grabbing assembly includes a central support mechanism connected to the upper part of the column, and both sides of the central support mechanism are provided with a grabbing mechanism that can grab the upper edge of the top of the oil drum, and the two grabbing mechanisms are supported on the central support mechanism and are connected to form a whole by a connecting piece. The two bucket-grabbing mechanisms can swing up and down with the central support mechanism as the support point, and its structural features are: the bucket-grabbing mechanism includes a claw that can hook the inner side of the upper edge when rotating in the direction of the oil barrel, and a rotatable pressure head is provided under the claw. When the pressure head is forced to rotate in the direction of the forklift, it drives the claw to rotate in the direction of the oil barrel and hook the inner side of the upper edge, and when grabbing the bucket, the pressure head rests on the outer side of the upper edge. The bucket-grabbing mechanism also includes a return spring that can pull the claw to rotate in the direction of the forklift and separate the claw from the upper edge when the force on the pressure head disappears; the lower part of the column is provided with an auxiliary support block that can rest on the lower part of the oil barrel when the claw hooks the upper edge.

[0005] After adopting the above structure, when using the oil drum grabbing device to carry the oil drum, the fork sleeve is put on the fork of the forklift, the forklift is driven near the oil drum, and the tilt angle of the fork is adjusted so that the grab surface of the grabbing mechanism for the oil drum is tilted close to the upper edge of the oil drum. Since the two grabbing mechanisms of the grabbing assembly can swing up and down, the grabbing mechanism can be properly swung when close to each other, so that the pressure head is conveniently pressed against the outer side of the upper edge. After the pressure head contacts the outer side of the upper edge, the tilt angle of the fork is adjusted so that the upper edge applies pressure to the pressure head in the direction of the forklift, and the pressure head rotates in the direction of the forklift. When the pressure head rotates to a certain angle, the claw rotates toward the oil drum and hooks the inner side of the upper edge. At this time, the pressure head is pressed against On the outside of the upper edge, a claw hooks onto the inside of the upper edge, and the pressure head and claw grasp the upper edge. The inside of the upper edge refers to the inside of the circle where the upper edge is located, and the outside refers to the outside of the circle where the upper edge is located. At this time, the auxiliary support block rests on the lower part of the oil barrel. During the grasping process, the tilt angle of the forklift fork continuously changes, and the oil barrel is lifted and transported to the use location by changing the fork angle. The upper edge of the oil barrel is grasped by the claw and pressure head, and the lower part is supported by the auxiliary support block. Each oil barrel is grasped by two barrel-grabbing mechanisms. The barrel is secure during transportation and will not fall. This is highly safe and eliminates the need for manual lifting, reducing labor intensity. It can be operated by one person and improving transportation efficiency. When the oil barrel is transported to the desired location, the fork angle is adjusted to lower the barrel. The fork tilt angle is adjusted to reduce or eliminate the pressure of the upper edge on the pressure head. Under the action of the return spring, the claw is pulled back to its original position. The tilt angle of the fork also changes during the barrel placement process.

[0006] The bucket grabbing mechanism includes a shell, and a first upper connecting shaft arranged in a horizontal direction is provided on the upper part of the bucket grabbing mechanism. The outer sleeve of the first upper connecting shaft is provided with a rotatable first rotating sleeve. The pawl is fixedly connected to the first rotating sleeve through an upper rotating arm. The first rotating sleeve is also fixedly connected to one end of a reset spring, and the other end of the reset spring is connected to a fixed point on the bucket grabbing mechanism.

[0007] The bucket grabbing mechanism also includes a lower rotating arm support shaft arranged in the horizontal direction, the lower rotating arm support shaft is located below the first upper connecting shaft, the lower rotating arm support shaft is hinged to the lower rotating arm, and the lower rotating arm can rotate with the lower rotating arm support shaft as the axis; the pressure head is fixedly connected to the upper end of the lower rotating arm, a protrusion is fixedly connected to the first rotating shaft sleeve, and when the pressure head rotates toward the forklift, the squeezing protrusion drives the first rotating shaft sleeve to rotate and then drives the claw to rotate toward the oil barrel. The bucket grabbing mechanism also includes a blocking member that can prevent the lower rotating arm from rotating when the pressure head rotates in the direction away from the forklift.

[0008] The cross-section of the column is a rectangle with a notch, and the notch is opened on the side of the column near the oil drum. The upper part of the column is provided with a support shaft arranged in a horizontal direction for supporting the grabbing combination, and the two sides of the support shaft are respectively hinged with shaft-connecting side plates, and the shaft-connecting side plates can swing with the support shaft as the axis within the spatial range of the column cross-section. Two swing shafts arranged up and down and parallel to the support shaft are provided in the column, and the two ends of the swing shaft are respectively supported on two shaft-connecting side plates, and the two sides of the central support mechanism are respectively hinged to one end of the two connecting arms arranged up and down, and the other ends of the two connecting arms arranged up and down are respectively hinged to the two swing shafts arranged up and down in the column, and the connecting arms pass through the notch.

[0009] The supporting surface of the auxiliary supporting block for the oil drum is arc-shaped.

[0010] A flexible protective belt is provided on the supporting surface of the auxiliary supporting block to protect the side wall of the oil drum.

[0011] The bracket includes two columns.

[0012] When the pressure head of the grabbing mechanism of the oil drum grabbing device of the present invention is squeezed by the upper edge of the oil drum and rotated toward the forklift, the pressure head squeezes the protrusion to rotate. Since the protrusion, the upper rotating arm, and one end of the return spring are all connected to the first rotating shaft sleeve, the pawl and the upper rotating arm are fixedly connected, the first rotating shaft sleeve rotates with the protrusion, and then the upper rotating arm and the pawl also rotate at the same time, the pawl rotates toward the direction of the oil drum and hooks the inner side of the upper edge, the return spring is stretched, the pawl and the pressure head contact the inner side and the outer side of the upper edge respectively, thereby grabbing the upper edge, the upper part of each oil drum is grabbed by the two grabbing mechanisms, and the lower part of the oil drum is supported on the auxiliary support block, and the upper and lower parts work together. The oil drum is firmly grasped and carried without dropping. When placing the drum, the squeezing force of the upper edge on the pressure head is reduced to zero, and the squeezing force of the pressure head on the protrusion disappears. Under the action of the return spring, the return spring pulls the claw toward the forklift and rotates it, disengaging the claw from the upper edge, completing the drum placement. The forklift's fork tilt angle needs to be adjusted during the process of grabbing and placing the drum. The two drum grabbing mechanisms of the grabbing assembly can swing up and down, and the central support mechanism can also rock back and forth, giving the grabbing device a certain degree of elasticity, facilitating the grabbing and releasing of the upper edge during the process of grabbing and placing the drum, making operation more convenient. The drum grabbing device can carry two drums at a time, improving handling efficiency. The structure and principle of the drum grabbing device of the utility model are simple, easy to use, and save manpower and labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 12 The figure shows a schematic diagram of the appearance of a common polyester oil drum 100, which is cylindrical in shape and has an upper edge 101 around the top.

[0029] Reference Figure 1-14 , an oil drum grabbing device, including a bracket 1, the bracket 1 can be installed on a forklift fork (the forklift is a commonly used transportation tool in the factory, does not belong to the protection scope of the utility model, and is not shown in the figure), the bottom of the bracket 1 is provided with two fork sleeves 11 that can be put on the forklift fork, the bracket 1 also includes at least one column 12, the column 12 is fixedly connected to the fork sleeve 11 by a steel section, the column 12 can also be designed as one or other numbers, the utility model is described with two columns 12, the two columns 12 are set away from the forklift, and the upper part of each column 12 is installed A grabbing assembly for grabbing the oil drum 100 is provided, and the grabbing assembly is arranged on the side of the column 12 away from the forklift. When the fork sleeve 11 is put on the forklift fork, the column 12 is arranged away from the forklift, and the grabbing assembly is located on the side of the column 12 away from the forklift, that is, the grabbing assembly is facing away from the forklift. The grabbing assembly includes a central support mechanism 3 connected to the upper part of the column 12, and both sides of the central support mechanism 3 are provided with a bucket grabbing mechanism 2 that can grab the top edge 101 of the oil drum 100, that is, the grabbing assembly can grab the top edge 101 from two points, and the two bucket grabbing mechanisms 2 are connected as a whole. Figure 1As shown, the two bucket grabbing mechanisms 2 are connected as a whole through the connecting plate 5 and the connecting rod 7. The two bucket grabbing mechanisms 2 are both supported by the central support mechanism 3. Specifically, the support point of the central support mechanism 3 for the bucket grabbing mechanism 2 can be set in the middle of the connecting plate 5. The two bucket grabbing mechanisms 2 are symmetrically arranged on both sides of the central support mechanism 3. The two bucket grabbing mechanisms 2 can swing up and down with the central support mechanism 3 as the support point. When swinging, they are similar to a seesaw, but cannot rotate 360°. The bucket grabbing mechanism 2 has a certain swing amplitude to facilitate docking with the upper edge 101. If the bucket grabbing mechanism 2 is fixed and has no room for movement, it is inconvenient to grab the edge; as shown Figure 6 As shown, since the oil drum 100 is circular, the grasping surfaces of the two grabbing drum mechanisms 2 face the center of the oil drum 100, so that the grasping combination can grasp the upper edge 101 from two different points; the grabbing drum mechanism 2 includes a claw 21 that can hook the inner side of the upper edge 101 when rotating toward the oil drum 100. The inner side and outer side of the upper edge 101 mentioned in the utility model refer to the inner side and outer side of the circle where the upper edge 101 is located. A rotatable pressure head 22 is provided below the claw 21. When the pressure head 22 is subjected to the pressure applied by the upper edge 101 and rotates toward the forklift, it drives the claw to rotate toward the oil drum 100 and extend and hook the inner side of the upper edge 101. When grabbing the drum, the pressure head 22 rests on the outer side of the upper edge 101, and the claw 21 and the pressure head 22 respectively rest on the inner side and outer side of the upper edge 101 to realize grabbing the edge. The grabbing drum mechanism 2 also includes a reset spring 214. When the force on the pressure head 22 disappears, the reset spring 214 can pull the claw 21 toward the forklift The upper edge 101 of the oil drum 100 is connected to the upper edge 101 of the oil drum 100, and the lower edge 101 of the oil drum 100 is connected to the lower edge 101 of the oil drum 100. The lower edge 101 of the oil drum 100 is connected to the lower edge 101 of the oil drum 100, and the lower edge 101 of the oil drum 100 is connected to the lower edge 101 of the oil drum 100.

[0030] Reference Figure 1-6, 13-14, the bucket grabbing mechanism 2 includes a shell 23, the shell 23 is in the shape of a rectangular box, the connecting plate 5 and the connecting rod 7 are fixedly connected to the shell 23, an inner frame 24 is provided inside the shell 23, the shell 23 and the inner frame 24 are connected by a first upper connecting shaft 29 and a first lower connecting shaft 25 arranged in the horizontal direction, the upper end of the inner frame 24 is a claw cover 241 protruding from the shell 23, when the return spring 214 is in a natural state, the claw 21 is located in the claw cover 241, when grabbing the bucket, the claw 21 extends to the outside of the claw cover 241, the role of the claw cover 241 is to prevent the claw 21 from touching the oil barrel 100 when grabbing the bucket, causing inconvenience in grabbing the bucket, of course, the claw cover 241 can also be omitted, the shell 23 and the inner frame 24 are both connected to the shell , or only one shell can be set; the pressure head 22 extends out of the shell, which is convenient for squeezing the pressure head 22 by using the upper edge 101 when grabbing the bucket. The utility model is explained with the case where the shell includes an outer shell 23 and an inner frame 24. The first upper connecting shaft 29 is located at the upper part of the grab bucket mechanism 2, and the first lower connecting shaft 25 is located at the bottom of the grab bucket mechanism 2. The outer sleeve of the first upper connecting shaft 29 is provided with a rotatable first rotating shaft sleeve 212, and the buckle claw 21 is fixedly connected to the first rotating shaft sleeve 212 through the upper rotating arm 211. The upper rotating arm 211 and the buckle claw 21 can rotate synchronously with the first rotating shaft sleeve 212. The first rotating shaft sleeve 212 is also fixedly connected to one end of the return spring 214, and the other end of the return spring 214 is connected to a fixed point on the grab bucket mechanism 2, such as Figure 3 As shown, it is fixedly connected to the first lower connecting shaft 25, and of course it can also be connected to a fixed point such as the inner frame 24. One end of the return spring 214 connected to the first rotating sleeve 212 rotates with the first rotating sleeve 212. When the first rotating sleeve 212 rotates toward the oil barrel 100 together with the pawl 21 under the action of an external force, the return spring 214 is stretched. When the external force disappears, the return spring 214 retracts and resets, pulling the pawl 21 back toward the forklift. Figure 3 As shown, a horizontal lever 26 is provided in the housing 23. The lever 26 is used to prevent the pawl 21 from excessively rotating toward the forklift. When the pawl 21 retracts and resets, it will rapidly rotate toward the forklift under the action of rotational inertia. When the pawl 21 or the upper rotating arm 211 hits the lever 26, it can stop rotating. Of course, the lever 26 can also be omitted without affecting the use of the device. Figure 3As shown, the bucket grabbing mechanism 2 also includes a lower rotating arm support shaft 28 arranged in the horizontal direction. The lower rotating arm support shaft 28 is located below the first upper connecting shaft 29 and above the first lower connecting shaft 25. The lower rotating arm support shaft 28 is hinged to the lower rotating arm 221, and the lower rotating arm 221 can rotate around the lower rotating arm support shaft 28. The upper end of the lower rotating arm 221 is fixedly connected to the pressure head 22. A fixed protrusion 213 is provided on the first rotating shaft sleeve 212, and the pressure head 22 rotates toward the forklift direction. When the pressing head 22 is rotated in the direction away from the forklift, the lower rotating arm 221 can be blocked from rotating, so that the pressing head 22 stops rotating in the direction of the oil barrel 100, and the lower rotating arm 221 is in a vertical state. Figure 3 As shown, the blocking member is the first lower connecting shaft 25, and of course the blocking member can also be designed in other positions. Figure 3 As shown, the bucket grabbing mechanism 2 also includes at least one first damping spring 242, one end of the first damping spring 242 is connected to the outer shell 23, and the other end is connected to the inner frame 24. The first damping spring 242 plays a certain damping role, and may not be provided. Figure 3 As shown, a swing groove side plate 27 is provided on both sides of the lower rotating arm 221. The gap between the two swing groove side plates 27 is the swing space of the lower rotating arm 221, which plays a limiting role on the lower rotating arm 221. The upper end of the swing groove side plate 27 is fixedly connected to the first upper connecting shaft 29, and the lower part of the swing groove side plate 27 is fixed by the lower rotating arm support shaft 28. Of course, the swing groove side plate 27 can also be omitted.

[0031] Reference Figure 1 、 4 -8, the cross section of the column 12 is a rectangle with a notch, and the cross section refers to the horizontal cross section. The notch is opened on the side of the column 12 near the oil drum 100. The upper part of the column 12 is provided with a horizontal support shaft 4 for supporting the grabbing assembly. A plurality of support shaft holes 121 of different heights can be opened on the column 12. The support shaft 4 can be inserted into the support shaft holes 121 of different heights as needed. Specifically, the central support mechanism 3 is connected to the support shaft 4, and the bucket grabbing mechanism 2 is supported on the central support mechanism 3. The central support mechanism 3 includes a support frame 31, and the support frame 31 is connected to the two swing shafts through two connecting arms arranged above and below, such as Figure 4 、 5As shown, the central support mechanism 3 includes a second upper connecting shaft 32 and a second lower connecting shaft 33 which are horizontally arranged and pass through the support frame 31. The second upper connecting shaft 32 is located above the second lower connecting shaft 33. The two ends of the second upper connecting shaft 32 are respectively hinged to one end of the upper connecting arm 421, and the two ends of the second lower connecting shaft 33 are respectively hinged to one end of the lower connecting arm 431. The other end of the upper connecting arm 421 is hinged to the upper swing shaft 42, and the other end of the lower connecting arm 431 is hinged to the lower swing shaft 43.

The lower connecting arm 431 is fixedly connected to the third rotating sleeve 432. The center support mechanism 3 is connected to the swing shaft through the connecting arm, and the swing shaft is hung on the support shaft 4 through the shaft-connected side plate 41. When the shaft-connected side plate 41 swings, the center support mechanism 3 can swing accordingly, so that the center support mechanism 3 has a certain shaking space, which is convenient for grabbing the bucket. Figure 4 、 5 As shown, a second shock-absorbing spring 44 is provided between the upper connecting arm 421 and the lower connecting arm 431. One end of the second shock-absorbing spring 44 is connected to the upper connecting arm 421, and the other end is connected to the lower connecting arm 431. The second shock-absorbing spring 44 has a certain shock-absorbing effect and can also be omitted.

The first horizontal bottom plate 3112 is also fixedly connected to the inverted L-shaped plate 3113. The vertical plate of the inverted L-shaped plate 3113 is parallel to the front vertical plate 3111. There is a gap for installing the connecting plate 5 between the vertical plate of the inverted L-shaped plate 3113 and the front vertical plate 3111 through the central axis 34. A connecting column 35 is provided above the central axis 34, which passes through the vertical plate of the inverted L-shaped plate 3113 and the front vertical plate 3111. The connecting column 35 plays a connecting and fixing role. The first horizontal bottom plate 3112 or the connecting column 35 can also prevent the connecting plate 5 from rotating 360°. The connecting plate 5 can only be moved up and down within a certain range. The second upper connecting shaft 32 and the second lower connecting shaft 33 pass through the two side vertical plates 3121 to connect the central support mechanism 3.

[0033] Working process: When using, drive the forklift to put the fork on the fork sleeve 11, lift the oil barrel grabbing device and send it to the oil barrel 100 storage area, adjust the tilt angle of the fork, and make the barrel grabbing mechanism 2 tilt forward close to the upper part of the oil barrel 100, such as Figure 13 Left picture and Figure 14As shown in the enlarged view of J, the bucket grabbing mechanism 2 "lies" toward the oil barrel 100, and the pressure head 22 is pressed against the outer side of the upper edge 101 of the oil barrel 100. At this time, the claw 21 and the return spring 214 are in a natural state, and the inclination angle of the fork is adjusted to make the upper edge 101 squeeze the pressure head 22, so that the pressure head 22 rotates toward the forklift. During the rotation of the pressure head 22, the protrusion 213 is squeezed, and the first rotating sleeve 212 begins to rotate, and the claw 21 rotates toward the oil barrel 100 and extends to hook the inner side of the upper edge 101. The return spring 214 is stretched and accumulates elastic potential energy. At this time, the pressure head 22 is pressed against the outer side of the upper edge 101, and the claw 21 and the pressure head 22 grab the upper edge 101 from both inside and outside. The grabbing surface of the bucket grabbing mechanism 2 is close to vertical, and the arc-shaped auxiliary support block 6 is pressed against the lower part of the oil barrel 100. The angle of the fork is adjusted to lift the oil barrel 100 and then transport it to the destination area. The operation of placing the barrel is roughly the opposite of grabbing the barrel. The fork angle is adjusted to lower the barrel 100, and then the fork angle is adjusted again to tilt the gripping surface of the barrel gripping mechanism 2, so that the squeezing force of the upper edge 101 on the pressure head 22 gradually decreases until it disappears. Under the action of the return spring 214, the return spring 214 retracts and resets, driving the first rotating sleeve 212 to rotate. The claw 21 then rotates and retracts toward the forklift, separating from the inner side of the upper edge 101, completing the handling of the barrel 100. The barrel gripping device of the present invention can carry two barrels 100 at a time. When grabbing the barrel, no manual movement of the barrel 100 is required, and the operation can be completed by one person.

[0034] The oil drum grabbing device of the utility model has a simple structure. The upper edge of the oil drum is grabbed by the linkage of the pressure head and the buckle claw of the bucket grabbing mechanism. When the pressure head squeezes the outer side of the upper edge and rotates toward the forklift, the buckle claw is driven to rotate and extend toward the oil drum and then hook the inner side of the upper edge. The buckle claw and the pressure head grab the upper edge from both the inner and outer sides. The upper edge of each oil drum is grabbed at two places, and the bottom is supported by the arc-shaped auxiliary support block. The oil drum is grabbed stably and firmly, and the drum will not fall during the transportation process, which improves safety. One person can complete the transportation of the oil drum, saving manpower, eliminating the need for manual lifting, and reducing labor intensity. Two oil drums can be carried at a time, which improves transportation efficiency.
