Description

Technical Field

[0001] The present application relates to the technical field of forklift loading accessories, and in particular to a pipe loading accessory. Background Art

[0002] Forklifts play a very important role in the logistics system of an enterprise. They are the main force in material handling equipment and are widely used in ports, stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers. Forklift attachments are components installed on the front of the forklift for automated loading, unloading, stacking and transporting of goods. Forklift attachments in the prior art usually include a fork shovel frame and two parallel forks. The fork shovel frame is installed on the forklift through a lifting control cylinder and a pitching control cylinder, and the two parallel forks are installed on the fork shovel frame. When using the forklift attachment to transport goods, the parallel forks are extended under the goods by moving the forklift, and then the parallel forks are driven to rise by the lifting control cylinder to lift the goods off the ground, and the level of the goods is adjusted by the pitching control cylinder, and then the goods can be moved and transported by driving the forklift.

[0003] When the forklift attachment using the above-mentioned parallel fork spade structure is used to transport goods with a flat bottom surface, the goods can be stably placed on the parallel fork spade. However, when it is necessary to transport pipes with a circular cross-section, the pipes cannot be limited and fixed. The pipes are likely to roll on the surface of the parallel fork spade and fall off the parallel fork spade during transportation. Therefore, when transporting the pipes, ropes and other fixings must be used to bundle and limit the pipes placed on the parallel fork spade. The operation steps are cumbersome and time-consuming and labor-intensive, which seriously reduces the transportation efficiency of the pipes and increases the labor intensity of the staff and the cost of pipe transportation. Summary of the Invention

[0004] The purpose of the present application is to provide a pipe loading attachment to solve the problem in the prior art that the forklift attachment adopts a parallel fork-shovel structure and is unable to effectively limit and fix the pipe during the transportation process.

[0005] The pipe loading attachment provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, the upper fork body can be driven to rotate around the hinge axis between it and the lifting member through the rotating drive component, and the upper fork body can be rotated to be parallel to the lower fork body. The lifting member is then driven down by the lifting drive member, thereby driving the upper fork body to move downward. The pipe fittings can be clamped and fixed by the upper fork body and the lower fork body, so as to transport and transfer the pipe fittings, thereby playing a better role in limiting and fixing the pipe fittings, and preventing the pipe fittings from rolling off the lower fork body during transportation.

[0008] Optionally, a first buffer pad is further included, the upper fork body is L-shaped, the first buffer pad is fixed on the upper fork body, and the first buffer pad is located on the bottom surface of the upper fork body opposite to the lower fork body.

[0009] By adopting the above technical solution, the upper fork body is set to be L-shaped, which plays a good limiting role on the pipe in the length direction of the lower fork body, preventing the pipe from falling off the lower fork body along the length direction of the lower fork body. The first buffer pad can play a certain buffering effect, avoiding damage to the pipe when the upper fork body and the lower fork body clamp and fix the pipe.

[0010] Optionally, a second buffer pad is further included, which is fixed to the bottom of the lifting member and is used to abut against the upper surface of the lower fork body when the lifting member descends to the bottom dead point.

[0011] By adopting the above technical solution, the second buffer pad can prevent the lifting member from directly contacting the lower fork body during the descent process to cause collision vibration or damage, thereby achieving a good buffering and protective effect.

[0012] Optionally, the fork frame is provided with a transverse guide column, the lower fork body is provided with a guide sleeve, the lower fork body is slidably sleeved on the transverse guide column through the guide sleeve, the fork frame is provided with a guide boss, the lower fork body is provided with a limit block, and the limit block is engaged with the guide boss.

[0013] By adopting the above technical solution, a guide sleeve and a transverse guide column, as well as a guide structure in which a limit block and a guide boss cooperate with each other are used between the lower fork body and the fork frame, so that the lower fork body can be adjusted laterally and stably along the fork frame, thereby adapting to the fork loading and handling needs of different occasions or working conditions.

[0016] Optionally, a connecting frame is further included, which is fixed on the lower fork body, and the connecting frame is provided with a vertical slide rail. The side of the lifting member is provided with a pulley, and the pulley is slidably clamped in the vertical slide rail.

[0017] By adopting the above technical solution and arranging pulleys on the sides of the lifting member, the resistance and friction of the lifting member when it is lifted and lowered along the connecting frame can be reduced, thereby reducing losses and extending the service life.

[0018] Optionally, the rotary drive assembly includes a first oil cylinder, a connecting rod and a sleeve, the lifting member is provided with a hinge shaft, the sleeve is rotatably sleeved on the hinge shaft, the first oil cylinder is hinged to the lifting member, one end of the connecting rod is fixed to the sleeve, the other end of the connecting rod is hinged to the first piston rod of the first oil cylinder, and one end of the upper fork body is fixed to the sleeve.

[0019] By adopting the above technical solution, the connecting rod can be driven to rotate by controlling the extension and retraction of the first piston rod of the first oil cylinder, thereby driving the sleeve to rotate around the hinge shaft. When the sleeve rotates, the upper fork body can be driven to rotate around the axis of the hinge shaft, thereby controlling the opening and closing of the upper fork body, adjusting the angle of the upper fork body relative to the lower fork body, and realizing the clamping and limiting of the pipe fittings during transportation. The rotary drive assembly with the above structure is not only simple in structure and stable in operation, but also has a large torque and can adapt to heavier upper fork bodies.

[0020] Optionally, the translation drive member includes a second oil cylinder, which is fixed to the fork frame, and the second piston rod of the second oil cylinder is fixedly connected to the lower fork body. The lifting drive member includes a third oil cylinder, which is fixed to the connecting frame, and the third piston rod of the third oil cylinder is fixedly connected to the lifting member.

[0021] By adopting the above technical solution, the translation drive member adopts the second oil cylinder, and the lifting drive member adopts the third oil cylinder. When the first oil cylinder, the second oil cylinder and the third oil cylinder are working, they can be directly connected to the hydraulic system of the forklift body in the prior art. The use of the oil cylinder as the driving component is not only simple in structure and stable in operation, but also can be directly connected to the hydraulic system of the forklift body in the prior art, without the need to modify the forklift body in the prior art, and has good versatility and adaptability.

[0023] By adopting the above technical solution, since the pipe fittings are pushed onto the lower fork body by the lever, there is no need to manually roll the pipe fittings onto the lower fork body, thereby reducing the labor intensity of the staff. Since multiple sets of upper limit blocks are used to fit the upper parts of multiple pipe fittings of different diameters, multiple pipe fittings of different diameters can be limited and fixed, and multiple pipe fittings of different diameters can be transported at one time.

[0024] Optionally, it further includes a lifting frame, a reset rod and a vertical driving member, the vertical driving member is arranged on the support, the vertical driving member is transmission-connected to the lifting frame, and is used to drive the lifting frame to move vertically, multiple groups of upper limit blocks are respectively provided with hanging parts, the reset rod is fixedly connected to the lifting frame, and the reset rod corresponds to the hanging part.

[0025] By adopting the above technical solution, the lifting frame and the reset rod are driven to move upward by the vertical driving member, and the reset rod acts on the hanging part, thereby pushing multiple groups of upper limit blocks to move upward. When the multiple groups of upper limit blocks move to the upper dead point, the side shifting member is driven by the side shifting driving member to move toward the upper limit block, so that the top rod abuts against the side wall of the upper limit block, and the upper limit block is limited and fixed, thereby realizing automatic reset of the upper limit block.

[0026] To sum up, the present application includes at least one of the following beneficial technical effects: when the pipe loading accessories of the present application are in use, the fork frame is installed on the forklift body of the prior art and is connected to the hydraulic system of the forklift.

[0044] When the forklift 220 is lifted, the upper fork 20 is rotated about the hinge axis between the upper fork 20 and the lower fork 30, thereby reducing the labor of the operator.

[0046] The upper fork 20 is configured in an L-shape, thereby effectively limiting the position of the tube 220 along the length of the lower fork 30 and preventing the tube 220 from falling off the lower fork 30 along the length of the lower fork 30. The upper fork 20 can also be configured in other shapes that can prevent the tube 220 from falling off the lower fork 30 along the length of the lower fork 30.

The upper fork bodies 20 are divided into two groups, and the two groups of upper fork bodies 20 are located at the same height and parallel to each other.

[0054] By arranging the pulley 51 on the side of the lifting member 50, the resistance and friction of the lifting member 50 when it is lifted and lowered along the connecting frame 100 can be reduced, thereby reducing loss and extending the service life.

[0055] Reference Figure 3The rotary drive assembly 70 includes a first oil cylinder 71, a connecting rod 72 and a sleeve 73. The lifting member 50 is provided with a hinge shaft 52. The sleeve 73 is rotatably sleeved on the hinge shaft 52. The first oil cylinder 71 is hinged to the lifting member 50 through a first pin shaft 711. One end of the connecting rod 72 is fixed to the sleeve 73. The other end of the connecting rod 72 is hinged to the first piston rod 74 of the first oil cylinder 71 through a second pin shaft 741. One end of the upper fork body 20 is fixed to the sleeve 73.

[0056] By controlling the extension and retraction of the first piston rod 74 of the first oil cylinder 71, the connecting rod 72 is driven to rotate, thereby driving the sleeve 73 to rotate about the hinge axis 52. When the sleeve 73 rotates, it drives the upper fork 20 to rotate about the axis of the hinge axis 52 (i.e., the hinge axis between the upper fork 20 and the lifting member 50), thereby controlling the opening and closing of the upper fork 20 and adjusting the angle of the upper fork 20 relative to the lower fork 30, thereby achieving a clamping and limiting position of the pipe 220 during transportation. When the forklift is in the non-operating state, the upper fork 20 is adjusted to be parallel to the lower fork 30 by the rotation drive assembly 70, and the lower fork 30 is lowered to the first cushion 80 and the upper surface of the lower fork 30 by the lifting drive 60.

When the first oil cylinder 71, the second oil cylinder 41 and the third oil cylinder 61 are working, they can be directly connected to the hydraulic system of the forklift body in the prior art.

Therefore, it has good versatility and adaptability.

The upper limit block 140 is provided with an anti-slip boss 142 to prevent it from escaping from the vertical groove 131. The side shift drive member 160 is provided on the support 130. The side shift drive member 160 is transmission-connected with the side shift member 150 for driving the side shift member 150 to move toward or away from the upper limit block 140. The side shift member 150 is provided with multiple groups of push rods 151 that can respectively abut against the side walls of the upper limit block 140.

More specifically, the lower fork body 30 is provided with a groove 32, and the top plate 170 is slidably provided in the groove 32. The pushing drive member 180 is fixed in the groove 32. The pushing drive member 180 is transmission-connected to the top plate 170 for driving the top plate 170 to be raised and lowered relative to the lower fork body 30. The lower fork body 30 is provided with an upward-extending stop block 33.

[0062] When a forklift in the prior art is transporting pipe fittings 220, it is necessary to manually roll the pipe fittings 220 onto the lower fork body 30, and when transporting multiple pipe fittings 220 at a time, it can only adapt to pipe fittings 220 of one diameter. The pipe loading attachment of the present application can automatically push the pipe fittings 220 onto the lower fork body 30 during transportation, and can adapt to pipe fittings 220 of different diameters. The specific working principle is as follows: the lower fork body 30 is moved to the front of the pipe fitting 220 by the forklift body, and the lower fork body 30 is lowered to the ground, and at the same time, the upper fork body 20 is located above the pipe fitting 220, and the lever 111 is located behind the pipe fitting 220. At this time, the top rod 151 abuts against the side wall of the upper limit block 140, and the upper limit block 140 is in a position as shown in FIG. Figure 4 The horizontal push drive assembly 120 then drives the horizontal push member 110 and the lever 111 to move toward the fork frame 10, and then the lever 111 pushes the pipe 220 onto the lower fork body 30. When the plurality of pipes 220 are all located on the lower fork body 30, the pipe 220 is limited in the horizontal direction by the stop block 33 and the lever 111, and then the side shift drive member 160 drives the side shift member 150 to move away from the upper limit block 140, so that the push rod 151 is separated from the upper limit block 140, and the upper limit block 140 loses the friction of the push rod 151. After the abutment and limitation, it falls under the action of gravity, so that the lower ends of the multiple groups of upper limit blocks 140 contact the pipe fittings 220, and then the side shifting member 160 drives the side shifting member 150 to move toward the upper limit block 140, so that the push rod 151 abuts against the side wall of the upper limit block 140, and the upper limit block 140 is limited and fixed, and then the push driving member 180 drives the top plate 170 to move upward relative to the lower fork body 30, and pushes the pipe fittings 220. Under the interaction of the upper limit block 140 and the top plate 170, the pipe fittings 220 are clamped and limited, forming a Figure 11 The state shown in FIG. 1 prevents the pipe 220 from falling off the lower fork body 30 in the radial or axial direction during transportation. The push drive member 180 can adopt the fourth oil cylinder 181. The specific connection relationship between the fourth oil cylinder 181 and the lower fork body 30 and the top plate 170 is as follows: the fourth oil cylinder 181 is fixed to the lower fork body 30, and the fourth piston rod 182 of the fourth oil cylinder 181 is fixed to the top plate 170. The side shift drive member 160 can adopt the fifth oil cylinder 161.

Figure 9The specific structure of the horizontal push drive assembly 120 and the specific connection relationship with the upper fork body 20 and the horizontal push member 110 are as follows: the horizontal push drive assembly 120 includes a hydraulic motor 121 and a screw rod 122, the upper fork body 20 is provided with a slide groove 22, the horizontal push member 110 is slidably arranged in the slide groove 22, the screw rod 122 is rotatably arranged on the upper fork body 20, the hydraulic motor 121 is fixedly arranged on the upper fork body 20, and is transmission-connected with the screw rod 122, the horizontal push member 110 is provided with a screw hole 112, and the screw rod 122 is screwed to the screw hole 112.

[0063] Reference Figure 10 , also includes a lifting frame 190, a reset rod 200 and a vertical driving member 210. The vertical driving member 210 is arranged on the support 130. The vertical driving member 210 is transmission-connected to the lifting frame 190 and is used to drive the lifting frame 190 to move vertically. Multiple groups of upper limit blocks 140 are respectively provided with hanging parts 141. The reset rod 200 is fixedly connected to the lifting frame 190, and the reset rod 200 corresponds to the hanging part 141.

[0064] Since the plurality of upper limit blocks 140 will fall to different degrees after the pipe 220 is transported, the plurality of upper limit blocks 140 need to be reset when the pipe 220 is transported next time, that is, the plurality of upper limit blocks 140 are moved to Figure 4 Therefore, when the multiple sets of upper limit blocks 140 need to be reset, the vertical drive member 210 can be used to drive the lifting frame 190 and the reset rod 200 to move upward. The reset rod 200 acts on the hanging portion 141, thereby pushing the multiple sets of upper limit blocks 140 upward. When the multiple sets of upper limit blocks 140 move to the top dead center, the side shifting member 160 drives the side shifting member 150 to move toward the upper limit blocks 140, so that the push rod 151 abuts against the side wall of the upper limit blocks 140, thereby limiting and fixing the upper limit blocks 140. The vertical drive member 210 can be a sixth oil cylinder 211. The specific connection relationship between the sixth oil cylinder 211, the support 130, and the lifting frame 190 is as follows: the sixth oil cylinder 211 is fixed to the support 130, and the lifting frame 190 is fixed to the sixth piston rod 212 of the sixth oil cylinder 211.

[0065] The implementation principle of the pipe loading attachment of this embodiment is as follows: when it is necessary to transport multiple pipes 220 with different diameters, the lower fork body 30 is first moved to the front of the pipe 220 by the forklift body, and the lower fork body 30 is lowered to the ground, and then the horizontal push drive assembly 120 drives the horizontal push member 110 to move, and the pipe 220 is pushed onto the lower fork body 30 by the shift rod 111. When multiple pipes 220 are all located on the lower fork body 30, the pipe 220 is limited in the horizontal direction by the stop block 33 and the shift rod 111, and then the side shift drive member 160 drives the side shift member 150 to move away from the upper limit block 140, so that the upper limit block 140 is in the The upper limit block 140 is moved downwards by the side shifting member 160 so as to move toward the upper limit block 140, so that the top rod 151 abuts against the side wall of the upper limit block 140, and the upper limit block 140 is limited and fixed. The top plate 170 is then driven upwards relative to the lower fork body 30 by the pushing driving member 180 to push the pipe 220. Under the interaction between the upper limit block 140 and the top plate 170, the pipe 220 is clamped and limited, and then the pipe 220 can be transported and transferred. Since the pipe fitting 220 is pushed onto the lower fork body 30 by the lever 111, there is no need to manually roll the pipe fitting 220 onto the lower fork body 30, thereby reducing the labor intensity of the staff. Since multiple sets of upper limit blocks 140 are used to fit the upper parts of multiple pipe fittings 220 of different diameters, multiple pipe fittings 220 of different diameters can be limited and fixed, and multiple pipe fittings 220 of different diameters can be transported at one time.
