Description

Technical Field

[0001] The utility model relates to the technical field of gantry anti-collision, in particular to a gantry anti-collision buffer Background Art

[0002] The gantry milling machine, abbreviated as gantry mill, is a milling machine with a gantry frame and a horizontal long bed. The gantry frame of the gantry milling machine is usually made of steel structure and has a large mass. A large mass means a large inertia. Other structures, such as control cabinets, are also installed in the height direction of the gantry frame. When the gantry frame is driven by a motor to move on the track, collisions are likely to occur between adjacent gantries, which is prone to danger, damage to the machine, and will also generate a lot of noise Summary of the Utility Model

[0003] The purpose of the utility model is to propose a mechanical device that can prevent collisions between gantries

[0004] To achieve the above purpose, the utility model proposes a gantry anti-collision buffer. The buffer includes an anti-collision column and an anti-collision block. One end of the anti-collision column is fixed on the gantry device, and the other end is connected to the anti-collision block. The anti-collision block is a rubber anti-collision block and adopts a rubber structure. The buffers are oppositely arranged between adjacent gantry devices. The buffers are convexly fixed on the adjacent gantry devices

[0005] Further, one end of the anti-collision column is fixed to the gantry device through a fixing plate, and the anti-collision column and the fixing plate are welded into an integral structure

[0006] Further, four through holes are provided on the fixing plate, which facilitates the fixing of the fixing plate on the gantry device after the screws pass through the through holes

[0007] Further, a counterbore is dug in the rubber anti-collision block, and a threaded hole is provided on the anti-collision column. The counterbore and the threaded hole are connected by a screw head, so that the rubber anti-collision block and the anti-collision column are connected

[0008] Further, the buffer is fixed at the side end near the bottom of the gantry frame of the gantry device and protrudes from the gantry device. The buffers on adjacent gantry devices are oppositely arranged

[0009] Further, when the buffers oppositely arranged on adjacent gantry devices collide, the distance between the adjacent gantry devices is 150 mm

[0010] Compared with the prior art, the advantages of the utility model are as follows

[0011] 1. The utility model absorbs the energy generated when the buffer collides in a compressed form by setting rubber anti-collision blocks, taking advantage of the flexibility of rubber, reducing the rigid impact of the collision on the anti-collision column, and preventing damage caused by the collision of the buffer. At the same time, compared with the huge noise generated when hard objects collide, the rubber anti-collision block is used as the collision head when the buffer of the utility model collides, effectively reducing the noise.

[0012] 2. Through the gantry anti-collision buffer of the utility model, a safe distance can always be maintained between adjacent gantries, thus effectively avoiding collisions between gantries, reducing the risk of collision, and also avoiding damage to the equipment on the gantry device.

[0018] To make the objectives, technical solutions and advantages of the utility model clearer, the technical solutions of the utility model will be further described below.

[0019] This embodiment provides a gantry anti-collision buffer, as Figures 1-5 shown. The buffer includes an anti-collision column 2 and an anti-collision block 1. One end of the anti-collision column 2 is fixed to the gantry device through a fixing plate 4, and the fixing plate 4 and the anti-collision column 2 form an integrated structure by welding; the other end is connected to the anti-collision block 1. The anti-collision block 1 is a rubber anti-collision block with a rubber structure, and a counterbore is dug in the rubber anti-collision block 1, as Figure 1As shown, threaded holes are provided on the anti-collision column 2. The anti-collision column 2 and the anti-collision block 1 are connected and fixed by a screw 3 passing through the countersunk hole and the threaded hole. At this time, the screw head of the screw 3 is sunk in the rubber anti-collision block 1. The gantry anti-collision buffer is fixed at a position near the bottom end on the side of the gantry of the gantry device and protrudes from the gantry device. The buffers between adjacent gantry devices are arranged oppositely, so that when the adjacent gantry devices move relatively, the oppositely arranged buffers between the adjacent gantry devices collide first. When the buffers collide, a safety distance of 150 mm is maintained between the adjacent gantry devices.

[0020] In this embodiment, as Figures 2-4 shown, the height of the anti-collision column 2 is 350 mm, and the size of the fixing plate 4 welded to the end of the anti-collision column 2 is 200X90 mm. Four through holes are provided on the fixing plate 4. As Figure 3 shown, the diameter of the through hole is 10 mm, the distance between adjacent through holes in the horizontal direction is 164 mm, and the distance between adjacent through holes in the vertical direction is 54 mm. After using screws to pass through the through holes, the fixing plate 4 is fixed to the gantry device.

[0021] In this embodiment, a top plate 5 with a size of 130X100 mm is also welded to one end of the anti-collision column 2 connected to the anti-collision block 1. A threaded hole corresponding to the countersunk hole of the anti-collision block 1 is provided at the center position of the top plate 5. The thicknesses of both the top plate 5 and the fixing plate 4 are 10 mm. As Figure 5 shown, the length of the anti-collision block 1 is 60 mm.

[0022] In this embodiment, when the adjacent gantry devices move relatively, the oppositely arranged buffers between the adjacent gantry devices collide first. When colliding, a safety distance of 150 mm is always maintained between the adjacent gantry devices, thereby preventing the direct collision of the gantry devices.

[0023] The above is only the preferred embodiment of the present utility model and does not impose any limitation on the present utility model. Any person skilled in the art within the technical field, without departing from the technical solution of the present utility model, making any form of equivalent substitution or modification and other changes to the technical solution and technical content disclosed by the present utility model are still within the content of the technical solution of the present utility model and still belong to the protection scope of the present utility model.
