Description

Technical Field

[0001] The utility model relates to the technical field of flexible suspension cranes, in particular to an anti-overturning flexible suspension crane. Background Art

[0002] The flexible modular suspension crane is composed of components such as a suspension device, a track, a switch, a traveling trolley, an electric hoist, a mobile power supply device and a control device. The flexible modular suspension crane is usually suspended on the roof or beam of a factory building to realize direct aerial transportation of materials. Therefore, it is widely used in material transportation links or systems in various industries.

[0003] The traditional flexible suspension crane has four supporting columns, and a transfer area is formed between the four columns. The walking trolley can only drive the electric hoist to move within the transfer area, resulting in the cargo transfer range being limited to between the four columns, and long-distance transfer is impossible. Especially for production lines with longer extension lengths, traditional flexible suspension cranes cannot adapt to long-distance production lines, and long-distance transportation of goods still needs to rely on auxiliary equipment such as trolleys. Utility Model Content

[0004] The utility model aims to provide an anti-overturning flexible suspension crane capable of long-distance transfer, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A tip-overturning-proof flexible suspension crane comprises four columns, an electric hoist and two guide rails which are symmetrically arranged and extend along the length direction of a production line. A pair of sliding seats are slidably mounted on the two guide rails. Four columns are vertically mounted on the four sliding seats in a one-to-one correspondence. A driving mechanism is provided on the side of the guide rail on one side. The driving mechanism is used to drive the two sliding seats on the same side to move and adjust along the extension direction of the guide rail. A double-axis moving group is provided between the tops of the four columns. The electric hoist is arranged between the four columns through the double-axis moving group. The double-axis moving group is used to drive the electric hoist to move forward and backward or left and right.

[0007] It can be seen that the double-axis moving group can drive the electric hoist to move forward and backward or left and right within the range formed by the four columns, thereby realizing a small-range transfer of goods. The driving mechanism can drive the goods to be adjusted over a long distance along the length of the guide rail, so that the crane can meet the production needs of longer production lines and ensure that the goods can be transported to any part of the production line, greatly improving the range of cargo transfer. The overall structural layout is reasonable and practical, and it is worthy of wide promotion.

[0008] Furthermore, the guide rail is composed of a base and a T-shaped portion fixed on the top of the base, the base is fixed on the workshop floor, the sliding seat has a T-shaped groove matching the shape of the T-shaped portion, and the sliding seat is matched and sleeved on the T-shaped portion.

[0009] Furthermore, the driving mechanism includes a guide seat, a threaded rod, a driving motor, a nut seat, a C-shaped arm and a connecting plate. The guide seat is fixed to the side of the base on one side. The guide seat is provided with a slide groove. The threaded rod is rotatably installed in the slide groove. The driving motor is fixed on one side of the guide seat. The output shaft of the driving motor extends through the slide groove and is fixedly connected to one end of the threaded rod. The nut seat is limitedly slidably installed in the slide groove and is threadedly mounted on the threaded rod. One end of the C-shaped arm is fixed to the side of the nut seat, and the other end is fixed with a connecting plate. Two connecting rods are fixed on the connecting plate. The connecting rods are fixedly connected to the two sliding seats on the T-shaped portion on the same side in a one-to-one correspondence.

[0010] Furthermore, the dual-axis moving group includes a first moving group and a second moving group. The first moving group is provided between the two columns on the same side, the second moving group is provided between the two first moving groups, and the electric hoist is provided below the second moving group. The first moving group is used to drive the electric hoist to translate and adjust along the length direction of the guide rail, and the second moving group is used to drive the electric hoist to translate and adjust along the direction perpendicular to the guide rail.

[0011] Furthermore, the first moving group includes a first slide rail and a first-shaped trolley. The first slide rail is fixed between the top ends of the two columns on the same side. The first slide rail is mounted on the first-shaped trolley. The second moving group is arranged between the two first-shaped trolleys.

[0012] Furthermore, the second moving group includes a second slide rail, a second walking trolley and a mounting seat. The second slide rail is fixed between the outer walls of the two first-shaped walking trolleys. The second walking trolley is matched with the second slide rail. The mounting seat is fixed on the lower end surface of the second walking trolley, and the electric hoist is installed on the lower surface of the mounting seat.

[0013] Furthermore, auxiliary reinforcement rods are fixed between the columns on the guide rail on one side and the columns on the guide rail on the other side and at corresponding positions.

[0014] Furthermore, sliding blocks are slidably mounted on the two auxiliary reinforcement rods, connecting arms are fixed to the sides of the two sliding blocks, and the two connecting arms are fixedly connected to the two sides of the mounting seat respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0016] 1. The utility model drives the electric hoist to move forward and backward or left and right within the range formed by four columns through the operation of the double-axis moving group, thereby realizing the small-range transfer of goods. The operation of the driving mechanism can drive the goods to be adjusted over a long distance along the length direction of the guide rail, so that the crane can meet the production needs of longer production lines, and can ensure that the goods can be transported to any part of the production line, which greatly improves the range of goods transfer. The overall structural layout is reasonable, the practicability is high, and it is worthy of wide promotion.

[0017] 2. The utility model uses auxiliary reinforcing rods to fix the ends of the two columns on the opposite sides one by one, and uses the first slide rails to fix the tops of the two columns on the same side one by one. The two first slide rails and the two auxiliary reinforcing rods form a U-shaped structure. Combined with the vertical arrangement of four columns, the overall stability of the crane is ensured, which is beneficial to improving the load capacity of the crane, and can prevent the crane from overturning due to a heavy load, and the crane is highly safe to use.

[0018] 3. The utility model fixes connecting arms on both sides of the mounting seat, fixes sliding blocks at the ends of the connecting arms, and slides the sliding blocks correspondingly on the auxiliary reinforcement rods. The sliding cooperation between the sliding blocks and the auxiliary reinforcement rods is utilized to provide limiting guiding and supporting functions for the mounting seat, thereby ensuring that the electric hoist moves more smoothly and stably in the direction perpendicular to the guide rail. At the same time, the auxiliary reinforcement rods serve as connecting auxiliary reinforcement parts for the two opposite columns, thus killing two birds with one stone.

[0029] When the present anti-overturning flexible suspension crane is in use, the electric hoist 5 is used to suspend and lift the cargo, and the double-axis moving group 4 is used to drive the electric hoist 5 to move forward and backward or left and right within the range formed by the four columns 3, so as to realize the small-range transfer of cargo. The driving mechanism 6 can drive the two sliding seats 2 and the columns 3 on one side to slide along the length direction of the guide rail 1, and under the connection action of the double-axis moving group 4, the sliding seat 2 and the column 3 on the other side are driven to move synchronously, so as to drive the cargo to be adjusted over a long distance along the length direction of the guide rail 1. Since the guide rail 1 extends along the length direction of the production line, it can ensure that the cargo can be transported to any part of the production line, which greatly improves the range of cargo transfer and enables the present crane to meet the production needs of a longer production line. The overall structural layout is reasonable and the practicability is high, so it is worthy of wide promotion.

[0030] Specifically, the guide rail 1 consists of a base 12 and a T-shaped portion 11 fixed on the top of the base 12. The base 12 is fixed on the workshop floor. The sliding seat 2 has a T-shaped slot 21 that matches the shape of the T-shaped portion 11. The sliding seat 2 is matched and mounted on the T-shaped portion 11. The base 12 is fixed to the ground, and the T-shaped portion 11 is fixed above the base 12 to achieve fixed installation of the T-shaped portion 11. The sliding seat 2 is matched and mounted on the T-shaped portion 11 through the T-shaped slot 21. The design of the T-shaped structure can provide a limiting and guiding effect on the sliding seat 2 to ensure that the sliding seat 2 can only slide along the length direction of the T-shaped portion 11, thereby ensuring the overall stability of the crane.

[0031] Specifically, the driving mechanism 6 includes a guide seat 61, a threaded rod 62, a driving motor 63, a nut seat 64, a C-shaped arm 65 and a connecting plate 66.

The driving motor 63 is fixed to one side of the guide seat 61. The output shaft of the driving motor 63 extends through the slide groove 611 and is fixedly connected to one end of the threaded rod 62. The nut seat 64 is limitedly slidably installed in the slide groove 611 and is threadably mounted on the threaded rod 62. The C-shaped arm 65 is provided with a connecting plate 66. One end of the C-shaped arm 65 is fixed to the side of the nut seat 64, and the other end is fixed with a connecting plate 66. Two connecting rods 67 are fixed on the connecting plate 66. The connecting rods 67 are fixedly connected to the two sliding seats 2 on the T-shaped portion 11 on the same side in a one-to-one correspondence. The threaded rod 62 is driven to rotate by the driving motor 63. The rotating threaded rod 62 threadably drives the nut seat 64 to slide along the slide groove 611. Under the fixed connection of the C-shaped arm 65, the connecting plate 66 and the connecting rod 67, the two sliding seats 2 on the same side can be driven to slide along the T-shaped portion 11, providing drive for the long-distance transfer of goods.

[0032] Specifically, the dual-axis moving group 4 includes a first moving group 41 and a second moving group 42. The first moving group 41 is provided between the two columns 3 on the same side, the second moving group 42 is provided between the two first moving groups 41, and the electric hoist 5 is provided below the second moving group 42. The first moving group 41 is used to drive the electric hoist 5 to translate and adjust along the length direction of the guide rail 1, and the second moving group 42 is used to drive the electric hoist 5 to translate and adjust along the direction perpendicular to the guide rail 1.

[0033] The first moving group 41 includes a first slide rail 411 and a first-shaped trolley 412. The first slide rail 411 is fixed between the top ends of the two columns 3 on the same side. The first-shaped trolley 412 is mounted on the first slide rail 411. The second moving group 42 is arranged between the two first-shaped trolleys 412.

The mounting seat 423 is fixed on the lower end surface of the second walking trolley 422. The electric hoist 5 is installed on the lower surface of the mounting seat 423.

[0035] The first-shaped trolleys 412 on both sides move synchronously along the first slide rail 411, thereby driving the second slide rail 421 to move in a direction parallel to the length of the guide rail 1. The second trolley 422 moves along the second slide rail 421, which can drive the electric hoist 5 to move in a direction perpendicular to the guide rail 1, thereby providing drive for small-range adjustment of the goods.

[0036] In addition, the two first-shaped trolleys 412 are symmetrically arranged and move synchronously, thereby ensuring that the movement amounts of the two ends of the second slide rail 421 are connected to avoid jamming.

[0037] In addition, it is worth mentioning that the first slide rail 411, the first type trolley 412, the second slide rail 421, the second trolley 422 and the electric hoist 5 all adopt existing technologies, and the specific structure and working principle will not be described in detail in this application.

[0038] Specifically, an auxiliary reinforcing rod 7 is fixed between the column 3 on the guide rail 1 on one side and the column 3 on the guide rail 1 on the other side and at the corresponding position. The auxiliary reinforcing rod 7 is used to fix the ends of the two columns 3 on the opposite side one by one, and the tops of the two columns 3 on the same side are fixed one by one by the first slide rail 411. The two first slide rails 411 and the two auxiliary reinforcing rods 7 form a structure in the shape of a U.S.-shaped structure. Combined with the vertical arrangement of the four columns 3, the overall stability of the crane is ensured, which is beneficial to improving the load capacity of the crane, and can prevent the crane from overturning due to a heavy load, and the crane has high safety.

[0039] Specifically, sliding blocks 9 are slidably mounted on the two auxiliary reinforcement rods 7, and connecting arms 8 are fixed on the sides of the two sliding blocks 9. The two connecting arms 8 are fixedly connected to the two sides of the mounting seat 423 respectively. By fixing the connecting arms 8 on both sides of the mounting seat 423, fixing the sliding blocks 9 at the ends of the connecting arms 8, and slidingly mounting the sliding blocks 9 on the auxiliary reinforcement rods 7 accordingly, the sliding blocks 9 and the auxiliary reinforcement rods 7 are used to provide a limiting guiding and supporting function for the mounting seat 423, thereby ensuring that the electric hoist 5 moves more smoothly and stably in the direction perpendicular to the guide rail 1. At the same time, the auxiliary reinforcement rod 7 serves as a connecting auxiliary reinforcement piece for the two opposite columns 3, thereby killing two birds with one stone.
