DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the crane pipe rotation auxiliary device provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part B is shown; Figure 4 for Figure 2 An enlarged schematic diagram of part C is shown; Figure 5 It is a schematic diagram of the connection structure of the annular handle, the anti-slip protrusion block, the driving arm, the driven arm and the connecting sleeve.
[0023] The crane pipe rotation auxiliary device includes: a column 1, an inner arm 2, an outer arm 3, an outrigger arm 4 and a joint 5. The inner arm 2 is rotatably connected to the column 1, and the inner arm 2, the outer arm 3, the outrigger arm 4 and the joint 5 are connected in sequence to form a whole. The column 1 bears the dead weight of the whole formed by the inner arm 2, the outer arm 3, the outrigger arm 4 and the joint 5 connected in sequence, the load of the maximum wind load, and the weight of the oil being transported. At the same time, the column 1 serves as a connection channel for the fluid from the transport pipeline to the arm assembly. The above is the prior art and will not be described in detail here. It also includes a straight-line driving member 6 and a supporting leg 7; the driving member 6 includes a driving arm 601, a driven arm 602 shorter than the driving arm 601, a connecting sleeve 603 and a supporting leg 7; an annular limiting groove 604 is opened along the outer circumference of the column 1; the connecting sleeve 603 is rotatably mounted on the column 1 and the connecting sleeve 603 is located in the limiting groove 604, the connecting sleeve 603 can rotate freely around the column 1, and the limiting groove 604 supports the connecting sleeve 603 to prevent it from axially moving along the column 1. One end of the driving arm 601 is fixedly connected to the connecting sleeve 603 and one end of the driven arm 602 is fixedly connected to the connecting sleeve 603, forming a straight-line driving member 6; the other end of the driven arm 602 is fixedly connected to the inner arm 2; when rotating, the driving arm 601 is stressed, and the integrated structure of the driving arm 601, the connecting sleeve 603 and the driven arm 602 rotates around the column 1 with the connecting sleeve 603, and the driven arm 602 drives the inner arm 2, the outer arm 3, the outrigger arm 4 and the joint 5 to form an overall rotation. Since the driving arm 601 is longer than the driven arm 602, the rotation process is labor-saving; since the driving member 6 is straight-lined, when the other end of the driven arm 602 is fixedly connected to the inner arm 2, the driving arm 601 is located on the side of the column 1 away from the inner arm 2. Therefore, during the rotation operation, the operator is far away from the tank car, so the operation is safe. Since the connecting sleeve 603 is sleeved on the column 1, the column 1 will not block the rotation of the driving member 6, and the operation is convenient.
[0024] In some other embodiments, a support leg 7 is further included; the top end of the support leg 7 is fixedly connected to the inner arm 2, and the bottom end of the support leg 7 is fixedly connected to a universal wheel 8 and the universal wheel 8 is on the ground, so the support of the support leg 7 can balance the gravity torque of the driving arm 601 itself, so that the torque generated by the gravity of the driving arm 601 itself will not become a burden on the inner arm 2, thereby not destroying or slowly destroying the sealing connection between the inner arm 2 and the column 1, so as to protect the life of the sealing connection of the inner arm 2.
[0025] In some other embodiments, a buffer spring 9, a guide sleeve 10 and a guide column 11 are further included; the guide sleeve 10 is fixedly connected to the bottom of the support leg 7, the guide column 11 is fixedly connected to the XˋXˋ of the universal wheel 8, the guide sleeve 10 is slidably sleeved on the guide column 11, and the guide column 11 can slide freely along the guide sleeve 10. The buffer spring 9 is located in the guide sleeve 10, one end of the buffer spring 9 is fixedly connected to the guide sleeve 10, and the other end of the buffer spring 9 is fixedly connected to the guide column 11. When the ground is uneven, the buffer spring 9 is compressed and extended to buffer the bumps, thereby reducing the impact of the bumps on the inner arm 2.
[0026] In some other embodiments, a limit member 12 is further included, which includes a limit guide ring 1201 fixedly connected to the bottom end of the guide sleeve 10 and a limit guide plate 1202 fixedly connected to the top of the guide column 11 and protruding from the outer side surface of the guide column 11; the guide column 11 passes through the limit guide ring 1201 and the outer peripheral surface of the guide column 11 is in contact with the limit guide ring 1201, so the limit guide ring 1201 has a guiding effect on the guide column 11, so that the guide column 11 can only move back and forth along the axial direction of the guide sleeve 10; since the limit guide plate 1202 protrudes from the outer side surface of the guide column 11, the guide plate can prevent the guide column 11 from escaping from the guide sleeve 10. The limiting guide plate 1202 is located in the guide sleeve 10 and the outer peripheral surface of the limiting guide plate 1202 is in contact with the guide sleeve 10 , so the guide sleeve 10 has a guiding effect on the limiting guide plate 1202 , ensuring that the guide column 11 can freely reciprocate along the axial direction of the guide column 11 .
[0027] In some other embodiments, a ball 13 is rollingly connected to the outer circumference of the guide column 11, and a ball 13 is rollingly connected to the outer circumference of the limiting guide plate 1202. The ball 13 can reduce the friction resistance between the guide column 11 and the limiting guide ring 1201 and between the limiting guide plate 1202 and the limiting guide ring 1201, so that the buffer spring 9 is more sensitive in offsetting bumps.
[0028] In some other embodiments, a bearing 14 is provided between the connecting sleeve 603 and the column 1, and the bearing 14 is provided between the connecting sleeve 603 and the column 1. The bearing 14 is fixedly sleeved on the column 1 and the bearing 14 is located in the limiting groove 604, and the connecting sleeve 603 is fixedly sleeved on the bearing 14; the provision of the bearing 14 is conducive to reducing the rotational friction between the connecting sleeve 603 and the column 1. The bottom end surface of the connecting sleeve 603 is rollingly connected with a ball 13, and the ball 13 is in rolling contact with the supporting surface of the limiting groove 604; the limiting groove 604 supports the connecting sleeve 603 by contacting with the bottom end of the connecting sleeve 603, so the ball 13 is rollingly connected to the bottom end surface of the connecting sleeve 603, which is conducive to reducing the friction between the connecting sleeve 603 and the column 1. In summary, the provision of the bearing 14 and the ball 13 is conducive to saving effort in the rotation operation and making the rotation operation more sensitive.
[0029] In some other embodiments, the end of the driving arm 601 away from the connecting sleeve 603 is fixedly connected to the annular handle 15, and the center of the virtual circle where the annular handle 15 is located is located at the center of the connecting sleeve 603; since any point of the annular handle 15 can be used as the fulcrum when rotating and pushing to maintain the same driving force arm to push the entire driving member 6, when the driving arm 601 is rotated, the operator can stand in place and push the driving arm 601 to obtain the same pushing effect as walking and pushing the driving arm 601. However, standing in place to push the driving arm 601 has the following technical effects: first, it is safer to operate standing in place; second, it is more labor-saving to rotate. A number of anti-skid protrusions 16 distributed at equal distances are fixedly connected to the outer peripheral surface of the annular handle 15. When rotating, the anti-skid protrusions 16 can prevent the hand from slipping out of the annular handle 15, which is safer and more convenient to use.
[0030] The working principle of the crane pipe rotation auxiliary device provided by the utility model is as follows:
[0031] First, the rotation operation is focused on the driving arm 601. The integrated structure of the driving arm 601, the connecting sleeve 603 and the driven arm 602 rotates around the column 1 with the connecting sleeve 603. The driven arm 602 drives the inner arm 2, the outer arm 3, the outrigger arm 4 and the joint 5 to rotate in sequence. Since the driving arm 601 is longer than the driven arm 602, the driving force arm is longer than the driven arm 602, so the driving force can be less than the resistance, so the rotation process is labor-saving.
[0032] Second, since the driving member 6 is in a straight line shape and the driven arm 602 is fixedly connected to the inner arm 2, the driving arm 601 is located on the side of the column 1 away from the inner arm 2. Therefore, during the rotation operation, the operator is located in an area centered on the axis of the column 1, far away from the tank car, so the operation is safe.
[0033] Third, since the connecting sleeve 603 is sleeved on the column 1, the column 1 will not hinder the rotation of the driving arm 601, and the rotation operation is more convenient.
[0034] Compared with the related art, the crane pipe rotation auxiliary device provided by the utility model has the following beneficial effects:
[0035] The utility model provides a crane pipe rotation auxiliary device.
