Description

Technical Field

[0001] The utility model relates to the technical field of transport tools and is a transport device for liquid barrels. Background Art

[0002] Flange barrels are also called plastic chemical barrels and plastic chemical barrels. They are mostly made of plastic and are often used to hold liquid materials such as chemicals, dyes, medicines, and pesticides. The barrel bodies of commonly used flange barrels are mainly divided into round barrels and square barrels. The upper end of the barrel body is sealed with a flange cover. In order to match the flange cover, the upper part of the barrel body is usually a frustum section with a small top and a large bottom. In order to facilitate the handling of flange barrels, the frustum section on the upper part of the barrel body is usually symmetrically provided with two buckle parts that are recessed into the barrel.

[0003] During production operations, operators often need to transfer flange barrels filled with liquid materials to other places. Usually, the flange barrels are stacked on pallets manually, and then the pallets are picked up by forklifts to transfer the flange barrels to the operation workshop or storage warehouse. However, when flange barrels need to be transferred over a short distance and in very small quantities, the efficiency of using forklifts to transfer flange barrels is not high, but the transfer cost is relatively high. Therefore, such situations are usually handled manually. Since a single flange barrel filled with liquid is heavy, it often requires more than two people to cooperate in the transfer, and it takes multiple round trips, which makes the labor intensity of the operators high and the transfer efficiency low. Summary of the invention

[0004] The utility model provides a transport device for liquid barrels, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems of low forklift transport efficiency, high manual transport cost and labor intensity, and low transport efficiency when transporting flange barrels over short distances and in very small quantities.

DETAILED DESCRIPTION

[0020] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0021] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0022] The present invention is further described below in conjunction with the embodiments and drawings:

[0023] Embodiment 1: As attached Figure 1-3 As shown, the transport device for liquid barrels includes wheels and a frame inclined in a state of being lower on the left and higher on the right. A liquid barrel support plate 1 inclined in a state of being lower on the left and higher on the right is fixedly installed on the left side of the lower end of the frame, and a wheel is rotatably installed on the inner side of the lower left part of the frame; a hanger is fixedly installed on the upper side of the middle part of the frame, and the left end of the hanger is located on the left side of the wheel. The hanger is inclined in a state of being higher on the left and lower on the right, and at least one clamping mechanism is provided on the upper left end of the hanger, whose lower part can be opened in the front-rear direction to clamp the liquid barrel buckle hand 3.

[0024] During use, after pushing the device to the liquid barrel 2, the relative position between the clamping mechanism and the liquid barrel 2 can be fine-tuned by moving the frame forward, backward, left and right by the wheel. When the clamping mechanism is aligned with the liquid barrel 2, lift the right end of the frame to rotate the frame counterclockwise around the wheel axis, so that the hanger rotates counterclockwise with the frame, and gradually lower the clamping mechanism. During the lowering process of the clamping mechanism, the left end of the frame will also synchronously drive the liquid barrel support plate 1 to rotate downward. When the lower left end of the liquid barrel support plate 1 touches the ground, the clamping mechanism can just reliably clamp the liquid barrel buckle hand 3 (referred to as the buckle hand, the same below). At this time, press the right end of the frame downward to make the frame drive the hanger to rotate clockwise along the wheel axis, and lift the liquid barrel 2 through the clamping mechanism until the lower right end of the liquid barrel 2 is supported by the upper left side of the liquid barrel support plate 1. Stop rotating the frame, hold the right end of the frame and push and pull the device, and the liquid barrel 2 can be quickly transported to the designated location over a short distance. After the liquid material barrel 2 is transferred to the designated location, the frame is rotated in the opposite direction again to place the liquid material barrel 2 on the ground. At this time, the clamping mechanism can release the clamping of the liquid material barrel buckle hand 3 through manual assistance or an unlocking mechanism to release the liquid material barrel 2, completing the short-distance transfer of the liquid material barrel 2.

[0025] By using this device to manually transfer liquid barrels 2 over short distances and in small quantities, compared with forklift transportation, the transportation has high mobility and is more suitable for small space transportation operations, saving operating costs; compared with manual handling, the transportation operation is more efficient, saves more transportation operation time, and can greatly reduce the work intensity of operators.

[0026] According to the needs, the liquid barrel 2 in the present application refers to a flange barrel for holding liquid. The upper part of the flange barrel is a conical section with a small top and a large bottom, and the conical section is symmetrically provided with a concave buckle part 3; in order to strengthen the structural strength between the liquid barrel pallet 1 and the frame, a reinforcing rib 25 or a support beam can be provided between the lower right side of the liquid barrel pallet 1 and the left end of the frame. The liquid barrel pallet 1 can be a steel plate or a hard plastic plate. In order to make the frame rotate smoothly, there is a gap between the right side of the liquid barrel pallet 1 and the lower left part of the wheel; the clamping mechanism can be realized by a crossbeam and a V-shaped clamping assembly with an opening downward hinged on the crossbeam. The V-shaped clamping assembly can be opened outward, and its lower end can be bent into a hook shape toward the liquid barrel 2 so as to reliably hook the buckle part 3 of the liquid barrel 2. In order to prevent the V-shaped clamping assembly from collapsing during transportation, a torsion spring can be symmetrically provided between the upper end of the V-shaped clamping assembly and the crossbeam. The double torsion spring can enable the V-shaped clamping assembly to stably and reliably clamp the liquid barrel 2.

[0027] The above-mentioned handling device for liquid barrels can be further optimized and / or improved according to actual needs:

[0028] Embodiment 2: As attached Figure 1-3 As shown, an unlocking structure is provided between each clamping mechanism and the right part of the frame, and the unlocking mechanism can release the clamping state between the clamping mechanism and the handle 3 of the liquid barrel.

[0029] By such arrangement, after the liquid barrel 2 is transported to the designated location over a short distance, a single person can operate the unlocking mechanism to quickly release the clamping state between the clamping mechanism and the liquid barrel buckle hand 3, thereby realizing the unlocking and separation of the clamping mechanism and the liquid barrel 2, which can save more operators and operation time. According to the needs, the unlocking mechanism can be realized by a wire rope pulling mechanism or a traction rope pulling mechanism.

[0030] Embodiment 3: As attached Figure 1-3 As shown, the clamping mechanism includes a cylindrical guide rail 4, a front slider 5, a rear slider 6, an elastic tensioning portion, a front suspension rod 7, a rear suspension rod 8, a front pull rod 9 and a rear pull rod 10. A cylindrical guide rail 4 is provided at the upper left end of the hanger, and a front slider 5 and a rear slider 6 are slidably installed at an interval of front and rear on the outer side of the cylindrical guide rail 4. An elastic tensioning portion is provided between the front slider 5 and the rear slider 6. The front suspension rod 7 is fixedly installed at the middle part of the lower end of the front slider 5, the front pull rod 9 is fixedly installed at the rear side of the lower end of the front suspension rod 7, the rear suspension rod 8 is fixedly installed at the middle part of the lower end of the rear slider 6, and the rear pull rod 10 is fixedly installed at the front side of the rear suspension rod 8 corresponding to the position of the front pull rod 9.

[0031] During use, when the hoisting space between the front suspension rod 7 and the rear suspension rod 8 is aligned with the upper end of the liquid barrel 2, the right end of the frame is lifted upward to rotate the frame counterclockwise around the wheel axis, and the front suspension rod 7 and the rear suspension rod 8 can be lowered at the same time.

[0032] During the lowering process, when the rear end of the front tie rod 9 and the front end of the rear tie rod 10 touch the corresponding position on the outer side of the upper part of the frustum section of the liquid barrel 2, the front suspension rod 7 and the rear suspension rod 8 are continued to be lowered, so that the front suspension rod 9 and the rear suspension rod 10 can slide downward along the outer side of the frustum section of the liquid barrel 2. During the downward sliding of the front tie rod 9 and the rear tie rod 10, the front suspension rod 7 drives the front slider 5 and the rear suspension rod 8 drives the rear slider 6 to resist the tension of the elastic tensioning part, thereby making the front slider 5 and the rear slider 6 slide away from each other along the cylindrical guide rail 4, so that the front suspension rod 7 and the rear suspension rod 8 gradually open outward along the radial direction of the liquid barrel 2.

[0033] When the front tie rod 9 and the rear tie rod 10 reach the buckle part 3, the front slider 5 and the rear slider 6 slide towards each other under the elastic restoring force of the elastic tension part, so that the front suspension rod 7 and the rear suspension rod 8 quickly shrink along the radial direction of the liquid barrel 2, so that the front tie rod 9 and the rear tie rod 10 sink into the buckle part 3 and firmly buckle the liquid barrel 2. At this time, press down on the right end of the frame to rotate the frame clockwise around the wheel axis, and gradually lift up the front suspension rod 7 and the rear suspension rod 8. The front tie rod 9 and the rear tie rod 10 first firmly buckle the upper part of the corresponding buckle part 3, and then lift the liquid barrel 2 upward until the lower right end of the liquid barrel 2 is supported by the liquid barrel support plate 1 (such as Figure 3 As shown), stop rotating the frame, hold the right end of the frame and push and pull the device, so that the liquid barrel 2 can be quickly transported to the designated location over a short distance.

[0034] When the liquid barrel 2 is transferred to the designated location, the frame can be rotated counterclockwise to place the liquid barrel 2 on the ground. At this time, others can assist in manually pulling apart the front suspension rod 7 and the rear suspension rod 8, or the front suspension rod 7 and the rear suspension rod 8 can be pulled apart and unlocked through the unlocking structure, so that the front pull rod 9 and the rear pull rod 10 are disengaged from the corresponding buckle part 3, and the device can be moved away from the liquid barrel 2 to complete the transfer. In the short-distance transfer process, the transfer operation is efficient, the operation time is saved, and the labor intensity of the operators is low; using this device, even if the transfer personnel are relatively weak, they can easily carry the liquid barrel 2 over a short distance.

[0035] According to the requirements, in order to prevent the front slider 5 and the rear slider 6 from moving forward and backward along the cylindrical guide rail 4, a limit compression spring 26 can be installed on the outer side of the cylindrical guide rail 4 corresponding to the position between the front slider 5 and the front part of the left end of the hanger, and between the rear slider 6 and the rear part of the left end of the hanger; in order to facilitate the front pull rod 9 and the rear pull rod 10 to slide downward along the outer side of the cone section of the liquid barrel 2, and then reliably hook or buckle the buckle part 3 of the liquid barrel 2, the distance between the front suspension rod 7 and the rear suspension rod 8 should be equal to or slightly smaller than the maximum outer diameter of the liquid barrel 2, and the distance between the rear end of the front pull rod 9 and the front end of the rear pull rod 10 should be greater than the liquid barrel 2. The outer diameter of the flange cover of the barrel 2 is smaller than the distance between the two buckles on the liquid barrel 2, and the length of the front pull rod 9 and the rear pull rod 10 should also be compatible with the spacing between the front suspension rod 7 and the rear suspension rod 8 and the depth of the buckle part 3; in order to simplify the processing process and save processing costs, the front suspension rod 7 and the front pull rod 9, and the rear suspension rod 8 and the rear pull rod 10 can also be realized by sheet metal bending molding in the prior art; the elastic tensioning part can be realized by an elastic rubber tube or an elastic belt or an elastic rope in the prior art; in this embodiment, two clamping mechanisms (such as Figure 2 As shown), the two clamping mechanisms share the same cylindrical guide rail 4 to improve handling efficiency and reduce weight and save costs. In order to prevent the two clamping mechanisms from moving back and forth, a limit compression spring 26 can be provided between two adjacent clamping mechanisms.

[0036] Embodiment 4: As attached Figure 1-3 As shown, the unlocking mechanism includes a front hand brake 11, a rear hand brake, a first guide column 12, a second guide column 13, a front brake line 14, a third guide column, a fourth guide column 15 and a rear brake line 16. The front hand brake 11 and the rear hand brake are fixedly installed at the front and rear of the right end of the frame, respectively. A plurality of first guide columns 12 are arranged at intervals on the upper side of the right part of the frame and the upper side of the front of the hanger corresponding to the position of the front hand brake 11. The upper end of each first guide column 12 is provided with a wire through hole. A second guide column 13 is fixedly installed at the middle part of the upper side of the front slider 5. The upper end of the second guide column 13 A front brake line 14 is fixedly installed, and the other end of the front brake line 14 passes through all the line-passing through holes in sequence and is fixedly installed together with the left end of the front handbrake 11; a plurality of third guide columns are arranged at intervals on the upper right side of the frame and the upper rear side of the hanger corresponding to the position of the rear handbrake, and a line-passing through hole is provided at the upper end of each third guide column, and a fourth guide column 15 is fixedly installed on the middle part of the upper side of the rear slider 6, and a rear brake line 16 is fixedly installed on the upper end of the fourth guide column 15, and the other end of the rear brake line 16 passes through all the line-passing through holes in sequence and is fixedly installed together with the left end of the rear handbrake.

[0037] During use, after the liquid barrel 2 is transported to the destination, when the right end of the frame is lifted upward, the left end of the frame will rotate downward, and the liquid barrel 2 can be put on the ground again; then, after tightening the front handbrake 11 and the rear handbrake, the front brake line 14 can pull the front slider 5 forward to slide forward along the cylindrical guide rail 4, and the rear brake line 16 can pull the rear slider 6 backward to slide backward along the cylindrical guide rail 4, so that the distance between the front slider 5 and the rear slider 6 is increased, so that the distance between the rear end of the front pull rod 9 and the front end of the rear pull rod 10 is greater than the outer diameter of the liquid barrel 2, and the clamping mechanism and the liquid barrel buckle hand 3 are automatically unlocked to release the liquid barrel 2, so that a single person can realize the short-distance rapid transportation of the liquid barrel 2, which greatly saves labor costs and reduces the labor intensity of operators.

[0038] According to requirements, the front handbrake 11 and the rear handbrake can be implemented by bicycle handbrakes in the prior art, the first guide column 12 and the third guide column can be implemented by eye bolts or eye bolts in the prior art, and can also be implemented by other bolts or studs with holes on the head; when the number of clamping mechanisms is more than two, all front sliders 5 can be fixed together in series by the front brake line 14, and all rear sliders 6 can be fixed together in series by the rear brake line 16.

[0039] Embodiment 5: As attached Figure 2 As shown, the clamping mechanism also includes a roller 17, a front wheel mounting notch which opens backwards and passes through vertically is provided at the rear of the front pull rod 9, a rear wheel mounting notch which opens forwards and passes through vertically is provided on the rear pull rod 10 corresponding to the position of the front wheel mounting notch, and rollers 17 are rotatably installed in both the front wheel mounting notch and the rear wheel mounting notch.

[0040] By such an arrangement, the roller 17 can roll forward along the outer side of the conical section on the upper part of the liquid barrel 2, greatly reducing the friction between the front pull rod 9 and the rear pull rod 10 and the outer side wall of the liquid barrel 2, so that the clamping mechanism can clamp the buckle part 3 of the liquid barrel 2 more quickly, so as to avoid the front pull rod 9 and the rear pull rod 10 scratching the outer side wall of the liquid barrel 2, thereby improving the clamping operation efficiency.

[0041] Embodiment 6: As attached Figure 2 As shown, the elastic tensioning part is a tension spring 18 sleeved on the outside of the cylindrical guide rail 4, the front end of the tension spring 18 is fixedly installed together with the rear side of the front slider 5, and the rear end of the tension spring 18 is fixedly installed together with the front side of the rear slider 6.

[0042] During use, the tension spring 18 has the advantages of high working stability, high load capacity, low cost and long service life, which can enable the clamping mechanism of the device to clamp reliably for a long time.

[0043] Embodiment 7: As attached Figure 1-3 As shown, the front suspension rod 7 and the rear suspension rod 8 are both telescopic rods with adjustable lengths.

[0044] By such arrangement, the lengths of the front suspension rod 7 and the rear suspension rod 8 can be adjusted according to the height of the liquid barrel 2, so that the front pull rod 9 and the rear pull rod 10 can more easily hook the buckle 3 of the liquid barrel 2, and the liquid barrel 2 can be reliably lifted. According to the requirements, in order to prevent the limbs of the telescopic rod from being disjointed during the lifting process, the telescopic rod can be realized by a sleeve that is sheathed together inside and outside, and the limit fixation between the inner and outer sleeves can be realized by transverse pins or shear pins, etc. The telescopic rod can also be realized by a connecting rod with multiple sections of different lengths screwed together.

[0045] Embodiment 8: As attached Figure 1 , 3 As shown, the hanger includes a reinforcing strut 19, a front hanger 20 and a rear hanger 21. The front hanger 20 and the rear hanger 21 are fixedly installed at intervals on the front and rear sides of the middle upper part of the frame. Reinforcing struts 19 are fixedly installed between the lower right sides of the front hanger 20 and the rear hanger 21 and the corresponding positions on the upper left side of the frame. The rear side of the upper left end of the front hanger 20 is fixedly installed together with the front end of the cylindrical guide rail 4, and the front side of the upper left end of the rear hanger 21 is fixedly installed together with the rear end of the cylindrical guide rail 4.

[0046] By such arrangement, the cylindrical guide rail 4 can play the role of supporting the cross beam for the front hanger 20 and the rear hanger 21, so that the hanger has better stability and is not easily deformed during use. In this embodiment, in order to facilitate replacement and maintenance of the cylindrical guide rail 4, the cylindrical guide rail 4 and the hanger can be fixedly installed in a detachable installation manner.

[0047] Embodiment 9: As attached Figure 1 , 3 As shown, the frame includes a crossbeam, a booster handle 22, and a front frame 23 and a rear frame arranged at a front-rear interval. A crossbeam is fixedly installed between the lower left ends of the front frame 23 and the rear frame, and there is a gap between the right side of the crossbeam and the wheel. The left side of the crossbeam is fixedly installed with the right side of the liquid barrel support plate 1, and the booster handle 22 is fixedly installed on the upper side of the right end of the front frame 23 and the rear frame; the wheel includes an axle and a front wheel 24 and a rear wheel arranged at a front-rear interval. The axle is detachably installed on the inner side of the lower left part of the front frame and the rear frame, and the front wheel 24 and the rear wheel are installed on the outer side of the axle at a front-rear interval through bearings.

[0048] During use, the booster handle 22 makes it easier to control, push and pull the device, and the crossbeam can enhance the structural strength between the frame and the liquid barrel support plate 1; the double wheels are more stable, and the detachable axle makes it easier to replace and maintain the wheels.

[0049] According to needs, the front handbrake 11 and the rear handbrake can be installed on the left side of the corresponding booster handle 22 to better control the handbrake; in order to enhance the connection strength between the liquid barrel pallet 1 and the crossbeam, a number of reinforcing ribs 25 can be arranged at intervals between the lower side of the liquid barrel pallet 1 and the left side of the crossbeam; the front wheel 24 and the rear wheel are symmetrically arranged on the inner side of the lower left part of the frame.
