Description

Technical Field

[0001] The utility model relates to the technical field of crane installation equipment, in particular to auxiliary equipment for crane installation. Background Art

[0002] Gantry crane, commonly known as gantry crane, gantry crane, is a pictographic term for gantry crane, which is actually a gantry crane; common gantry cranes usually include two vertical frames fixed to the ground, the tops of the two frames are fixed with crossbeams by screws, the bottom of the crossbeams are slidably installed with mounting blocks, and the bottom of the mounting blocks are installed with electric hoists;

[0003] When assembling a gantry crane, first, the two frames are hoisted in sequence by a crane, so that the two frames are vertical and fixed on the ground, and then the crossbeam is hoisted by the crane so that the two ends of the crossbeam are aligned with the outside of the two frames and placed on the top of the two frames. When the crane hoists the crossbeam, the crossbeam is suspended in the air, making it difficult to locate the placement of the crossbeam. Therefore, when the crossbeam falls to the top of the two frames, the staff needs to manually support the crossbeam so that the two ends of the crossbeam are aligned with the outside of the two frames and placed on the top of the two frames. Although this method can align the crossbeam with the outside of the two frames and place it on the top of the two frames, it still has the following defects in actual use:

[0004] When the beam falls to the top of the two frames, the workers need to manually support the beam by using a lift to lift the workers to the top of the frames. Since the beam is long and suspended in the air, in windy weather or improper operation by the crane operator, it is easy to cause the beam to swing greatly in the air, which may cause injuries to the workers and is less safe.

[0005] Therefore, the present application proposes an auxiliary device for crane installation. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an auxiliary device for crane installation, which solves the problems mentioned in the background technology.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] An auxiliary device for crane installation, comprising a positioning mechanism, which is detachably mounted on a stand. There are two stands, and cross beams are arranged on the tops of the two stands. Moving blocks are slidably mounted on the cross beams in a horizontal direction, and an electric hoist is installed at the bottom of the moving blocks.

[0009] The positioning mechanism comprises a mounting block, on which guide columns in a horizontal direction are symmetrically slidably mounted, and positioning plates are fixedly mounted on the ends of the two guide columns that are away from each other and located on the outside of the mounting block, and a driving member acting on the two guide columns is mounted on the mounting block, which is used to make the two guide columns slide in the opposite direction or stop sliding on the mounting block, so as to clamp the stand frame through the two positioning plates;

[0010] A limit plate 1 in a vertical direction is fixedly installed on the top of the positioning plate, a guide plate 1 in an inclined shape is fixed on the top of the limit plate 1, and the tops of the two guide plates 1 are far away from each other. A vertical plate is fixedly installed on the mounting block, a limit plate 2 is installed on the top of the vertical plate, and a guide plate 2 in an inclined shape is fixedly installed on the top of the limit plate 2, and the top of the guide plate 2 is inclined outward in a direction away from the two limit plates 1.

[0011] Further: the driving member includes a bidirectional threaded rod rotatably mounted on a mounting block, the bidirectional threaded rod is threadedly connected to two guide columns, and an adjusting member acting on the bidirectional threaded rod is installed on the mounting block, which is used to rotate the bidirectional threaded rod on the mounting block.

[0012] Furthermore: the adjusting member includes a rotating rod which is horizontally and rotatably mounted on the mounting block, a driving bevel gear is coaxially fixed to the rotating rod, and a driven bevel gear meshing with the driving bevel gear is coaxially fixed to the bidirectional threaded rod.

[0013] Furthermore: a mounting groove is provided on one side of the two positioning plates close to each other, and a rubber pad is fixedly installed on the positioning plate and in the mounting groove. When the two positioning plates clamp the stand, the rubber pad contacts the stand and is hidden in the mounting groove.

[0014] Furthermore: handles are fixedly installed on the sides of the two positioning plates that are away from each other.

[0015] Further: the second limit plate is hinged to the top of the vertical plate through a hinge shaft, and an adjustment mechanism acting on the second limit plate is installed on the vertical plate, which is used to make the hinge shaft rotate or stop rotating on the vertical plate.

[0016] Furthermore: the adjusting mechanism comprises a worm wheel coaxially fixed to the hinge shaft, and a worm meshing with the worm wheel is rotatably mounted on the vertical plate.

[0017] Furthermore: a resisting plate which can resist against the second limiting plate is installed on the vertical plate. When the resisting plate resists against the second limiting plate, the second limiting plate is in a vertical shape.

[0018] The utility model provides an auxiliary device for crane installation. Compared with the prior art, it has the following features:

[0019] Beneficial effects:

[0020] 1. When assembling the crossbeam and the two vertical frames, ropes are tied to the two ends of the crossbeam. When the crane hoists the crossbeam and makes it fall to the top of the two vertical frames, the staff pulls the rope on the ground so that the end of the crossbeam is located between the two guide plates 1 and 2. When the crossbeam falls, it contacts the two guide plates 1 and 2, and can slide down along the two guide plates 1 and 2, so as to fall between the two limit plates 1 and 2, so that the crossbeam can be aligned with the outer sides of the two vertical frames and placed on the top of the two vertical frames, replacing the manual support of the crossbeam by the staff, effectively avoiding the situation in which the crossbeam swings greatly in the air due to strong winds or improper operation of the crane operator, causing injuries to the staff, and improving safety;

[0021] 2. By setting the rubber pad, when the two positioning plates clamp the stand, the rubber pad and the stand form a conflict and are hidden in the installation groove, increasing the friction between the two positioning plates and the stand, thereby improving the stability of the equipment during assembly;

[0022] 3. By setting the limit plate 2 to be hinged to the top of the vertical plate through the hinge axis, when assembling the gantry crane and assembling the equipment between the vertical frame, first use the adjustment mechanism to rotate the limit plate 2 around the hinge axis to a horizontal state, and then make the limit plate 2 fit with the top of the beam. The staff can then push the installation block and one side of the vertical frame to achieve the pre-positioning effect when assembling the equipment, thereby further facilitating the assembly of the equipment on the vertical frame.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] In order to solve the technical problems in the background technology, the following auxiliary equipment for crane installation is provided:

[0034] Combination Figure 1-Figure 6As shown, the utility model provides an auxiliary device for crane installation, including a positioning mechanism 1, which is detachably mounted on a vertical frame 2, the number of the vertical frames 2 is two, a crossbeam 21 is provided on the top of the two vertical frames 2, a moving block is slidably mounted on the crossbeam 21 in a horizontal direction, and an electric hoist 22 is installed at the bottom of the moving block. It is worth noting that: the installation structure in which the moving block is slidably mounted on the bottom of the crossbeam 21 and the electric hoist 22 is installed on the moving block are both prior arts, belonging to the well-known technical scope of those skilled in the art, and are not described in detail here; the positioning mechanism 1 includes a mounting block 11, on which guide columns 12 are symmetrically slidably mounted in a horizontal direction, and a positioning plate 13 is fixedly mounted on one end of the two guide columns 12 away from each other and located on the outside of the mounting block 11, and a driving member 14 acting on the two guide columns 12 is installed on the mounting block 11, which is used to make the two guide columns 12 slide in the opposite direction or stop sliding on the mounting block 11, so as to clamp the vertical frame 2 through the two positioning plates 13. When assembling the positioning mechanism 1, first pass The staff and the equipment are lifted to the top of the stand 2 by the lift. The staff moves the equipment so that the two positioning plates 13 are located on both sides of the stand 2, the two guide plates 132 are located above the stand 2, and the stand 111 is in contact with the stand 2. At this time, the two guide columns 12 are driven by the driving member 14 to slide in opposite directions on the mounting block 11 and approach each other, so that the two positioning plates 13 clamp the stand 2, and the equipment can be assembled on the stand 2; the top of the positioning plate 13 is fixedly installed with a vertical A limiting plate 131 is provided, the limiting plate 131 is of the same width as the positioning plate 13, an inclined guide plate 132 is fixed on the top of the limiting plate 131, and the tops of the two guide plates 132 are away from each other, a vertical plate 111 is fixedly installed on the mounting block 11, a limiting plate 23 is installed on the top of the vertical plate 111, the limiting plate 23 is of the same width as the vertical plate 111, an inclined guide plate 231 is fixedly installed on the top of the limiting plate 23, and the top of the guide plate 231 is inclined outwardly in a direction away from the two limiting plates 131.

When the crane hoists the crossbeam 21 so that the crossbeam 21 falls to the top of the two vertical frames 2, the staff pulls the rope on the ground so that the end of the crossbeam 21 is located between the two guide plates 1 132 and the two guide plates 31. When the crossbeam 21 falls, it contacts the two guide plates 1 132 and the two guide plates 31, and can slide and fall along the two guide plates 1 132 and the two guide plates 31, so as to fall between the two limit plates 1 131 and the limit plates 2 3, so that the crossbeam 21 can be aligned with the outer sides of the two vertical frames 2 and placed on the top of the two vertical frames 2, replacing the manual support of the crossbeam 21 by the staff, effectively avoiding the situation in which the crossbeam 21 swings greatly in the air due to strong winds or improper operation of the crane operator, causing injuries to the staff, thereby improving safety.

[0036] Embodiment 2

[0037] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0038] In this embodiment, the driving member 14 includes a bidirectional threaded rod 141 rotatably mounted on the mounting block 11, and the bidirectional threaded rod 141 is threadedly connected to the two guide columns 12. An adjusting member 4 acting on the bidirectional threaded rod 141 is installed on the mounting block 11, and is used to rotate the bidirectional threaded rod 141 on the mounting block 11. When in use, the bidirectional threaded rod 141 is rotated on the mounting block 11 by the adjusting member 4, so that the two guide columns 12 can slide in opposite directions on the mounting block 11. Since the bidirectional threaded rod 141 is threadedly connected to the two guide columns 12 and has self-locking properties, the positions of the two guide columns 12 can be fixed without rotating the bidirectional threaded rod 141 on the mounting block 11 through the adjusting member 4. By setting the adjusting member 4, it is convenient to rotate the bidirectional threaded rod 141.

[0039] In this embodiment, the adjusting member 4 includes a rotating rod 41 which is horizontally and rotatably mounted on the mounting block 11, and a driving bevel gear 42 is coaxially fixedly connected to the rotating rod 41, and a driven bevel gear 43 which meshes with the driving bevel gear 42 is coaxially fixedly connected to the bidirectional threaded rod 141. When in use, the driving bevel gear 42 is driven to rotate by rotating the rotating rod 41, so that the bidirectional threaded rod 141 can be driven to rotate on the mounting block 11 through the driven bevel gear 43, and the operation is simple. In this embodiment, the tooth ratio of the driving bevel gear 42 to the driven bevel gear 43 is two to one, so that the bidirectional threaded rod 141 is driven to rotate two circles when the rotating rod 41 rotates one circle, which is conducive to quickly adjusting the distance between the two positioning plates 13.

[0040] In this embodiment, a mounting groove 133 is provided on one side of the two positioning plates 13 that are close to each other, and a rubber pad 134 is fixedly installed on the positioning plate 13 and in the mounting groove 133. When the two positioning plates 13 clamp the stand 2, the rubber pad 134 comes into contact with the stand 2 and is hidden in the mounting groove 133. By providing the rubber pad 134, when the two positioning plates 13 clamp the stand 2, the rubber pad 134 comes into contact with the stand 2 and is hidden in the mounting groove 133, thereby increasing the friction between the two positioning plates 13 and the stand 2, thereby improving the stability of the device during assembly.

[0041] Embodiment 3

[0042] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0043] In this embodiment, handles 135 are fixedly mounted on the sides of the two positioning plates 13 that are away from each other. The two handles 135 are provided to facilitate the staff to take and move the device.

[0044] In this embodiment, the limit plate 23 is hinged at the top of the vertical plate 111 through the hinge shaft 32, and an adjustment mechanism 5 acting on the limit plate 23 is installed on the vertical plate 111, which is used to make the hinge shaft 32 rotate or stop rotating on the vertical plate 111. By setting the limit plate 23 to be hinged at the top of the vertical plate 111 through the hinge shaft 32, when the gantry crane is assembled, when the equipment is assembled between the vertical frame 2, the limit plate 23 is first rotated to a horizontal state around the hinge shaft 32 through the adjustment mechanism 5, and then the limit plate 23 is made to fit with the top of the beam 21, and the staff can push the installation block 11 and one side of the vertical frame 2 to achieve the pre-positioning effect when assembling the equipment, thereby further facilitating the assembly of the equipment on the vertical frame 2.

[0045] In this embodiment, the adjusting mechanism 5 includes a worm wheel 51 coaxially fixed to the hinge shaft 32, and a worm 52 meshing with the worm wheel 51 is rotatably mounted on the vertical plate 111. When in use, the hinge shaft 32 can be driven to rotate on the vertical plate 111 through the worm wheel 51 by rotating the worm 52. The operation is simple. Since the meshing of the worm wheel 51 and the worm 52 is self-locking, the worm wheel 51 will not rotate when the worm 52 is not rotated, so that the position of the limit plate 23 can be fixed, which is convenient for use.

[0046] In this embodiment, a resistance plate 6 which can resist the limit plate 23 is installed on the vertical plate 111. When the resistance plate 6 resists the limit plate 23, the limit plate 23 is in a vertical state. By setting the resistance plate 6, after the device is assembled on the vertical frame 2, the worm 52 is rotated to drive the limit plate 23 to rotate on the vertical plate 111 around the hinge shaft 32, so that the resistance plate 6 resists the limit plate 23, and the limit plate 23 can be made to limit the cross beam 21 in a vertical state, which is convenient for adjusting and resetting the limit plate 23.
