Technical Field

[0001] This utility model relates to the field of gantry crane technology, and in particular to an anti-collision block for raising the track beam of a gantry crane. Background Technology

[0002] With the rapid development of urban modernization, tunnel boring machine (TBM) construction involves the vertical transportation of tunnel segments, materials, and excavated soil. Among these, the use of gantry cranes at TBM construction sites is becoming increasingly widespread. Therefore, safety during the use of gantry cranes is of paramount importance. Anti-collision piers, as an indispensable device for gantry cranes, are used to buffer collision energy and ensure the safety of the gantry crane and personnel.

[0003] Existing technologies are mostly hydraulic or rubber crash barriers. However, hydraulic barriers are more expensive and have a more complex structure, making them difficult to repair when they malfunction. Rubber crash barriers, on the other hand, are exposed to wind, sun, and rain for a long time and need to be replaced regularly. They are also prone to aging and deformation, which reduces their protective effect and increases maintenance costs and workload.

[0004] Therefore, this application proposes a crash barrier that combines steel structure and reinforced concrete, which has good crash protection effect, low cost, long service life, and improves construction efficiency and safety. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an anti-collision pier for raising the track beam of a gantry crane.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A crash barrier for raising the track beam of a gantry crane includes a box-shaped cover plate fixed to the tail end of the gantry crane foundation cover plate and the enlarged foundation cover plate, and a box-shaped structure fixed to the tail end of the gantry crane foundation and the enlarged foundation. The lower end of the box-shaped structure is embedded inside the gantry crane foundation and the enlarged foundation. Concrete is poured inside the box-shaped structure to form a concrete-steel box. Two support beams are welded and fixed inside the box-shaped structure. The two ends of the two support beams are set at diagonal points inside the box-shaped structure. A buffer assembly is fixed to the side of the box-shaped structure facing the gantry crane.

[0007] In some embodiments, the housing includes side panels welded to the sides and a cover plate welded to the top.

[0008] In some embodiments, multiple embedded rods are arranged in an array on both sides of the housing, and the length of the embedded rod that cooperates with the enlarged foundation is greater than the length of the embedded rod that cooperates with the gantry crane foundation.

[0009] In some embodiments, the buffer assembly includes a tube and a collision head that slides inside the tube, with a spring fixed to the inner end of the collision head, and the height of the buffer assembly is the same as the height of the buffer at the end of the gantry crane.

[0010] In some embodiments, a plurality of stress relief plates are provided inside the pipe body, the plurality of stress relief plates are evenly spaced, and the contact positions of the plurality of stress relief plates with the pipe body are fixed by spot welding.

[0011] In some embodiments, a plurality of reinforcing ribs are welded laterally inside the housing, the reinforcing ribs being located between two support beams and welded and fixed to the support beams.

[0012] In some embodiments, the box body is provided with a reinforcing component to improve the strength of the box body. The reinforcing component includes a top plate fixed to the inside of the box body and a connecting beam for fixing the top plate to the support beam.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A type of anti-collision pier for raising the track beam of a gantry crane includes a box body 1 fixed to the tail end of the gantry crane foundation 2 and the enlarged foundation 3. The gantry crane foundation 2 and the enlarged foundation 3 are both concrete castings. The lower end of the box body 1 is embedded inside the gantry crane foundation 2 and the enlarged foundation 3. The box body 1 is made of steel structure. Concrete is poured inside the box body 1 to form a concrete steel box. Two support beams 5 are welded and fixed inside the box body 1. The two ends of the two support beams 5 are set at opposite corners inside the box body 1. Preferably, the upper end of the support beams 5 is set towards the gantry crane. The box body 1 has multiple rows of reinforcing ribs 8 welded horizontally inside. The multiple rows of reinforcing ribs 8 are located between two support beams 5 and are welded and fixed to the support beams 5. The box body 1 includes side plates 101 welded to the side and cover plates 102 welded to the top. The separate side plates 101 and cover plates 102 are used to facilitate the welding of support beams 5 and reinforcing ribs 8 inside the box body 1 and to facilitate subsequent concrete pouring. A buffer assembly 7 is fixed on the side of the box body 1 facing the gantry crane. The outer surface of the box body 1 above the gantry crane foundation 2 is sprayed with an anti-rust layer, which is anti-rust paint.

[0027] Understandably, before erecting the gantry crane, both the gantry crane foundation 2 and the extended foundation 3 are reinforced with steel bars, and a space for the box body 1 is reserved at the tail end. The support beam 5 and reinforcing rib 8 are welded diagonally inside the box body 1, and the side plate 101 is fixed by welding. Then, the box body 1 is placed in the reserved position, and the gantry crane foundation 2 and the extended foundation 3 are poured using formwork. At the same time, concrete is also poured into the box body 1. After pouring, it is vibrated. After it is completely solidified, the cover plate 102 is welded to the bottom of the box body 1 to seal it. By pouring the box body 1 into the gantry crane foundation 2 and the extended foundation 3 as one unit, and pouring concrete inside the box body 1, the impact strength of the box body 1 is improved, preventing damage after impact and affecting its use.

[0028] Specifically, multiple embedded rods 4 are arranged in an array on both sides of the housing 1. The length of the embedded rod 4 that cooperates with the enlarged base 3 is greater than the length of the embedded rod 4 that cooperates with the gantry base 2.

[0029] It is understandable that by setting multiple embedded rods 4, which cooperate with the door operator base 2 and the enlarged base 3 respectively, the fixing effect of the door operator base 2 and the enlarged base 3 on the housing 1 is improved.

[0030] Specifically, the buffer assembly 7 includes a tube body 701 and a collision head 702 that slides inside the tube body 701. A spring 703 is fixed to the inner end of the collision head 702. Multiple stress relief plates 704 are provided inside the tube body 701. The multiple stress relief plates 704 are evenly spaced. The other end of the spring 703 is fixed to the surface of the stress relief plate 704 near the collision head 702. The multiple stress relief plates 704 are fixed to the tube body 701 at the contact position by spot welding. The tube body 701 is fixed to the side of the housing 1 by a flange. The height of the buffer assembly 7 is the same as the height of the buffer at the end of the gantry crane.

[0031] Understandably, when the gantry crane collides with the surface of the housing 1, the buffer at the end of the gantry crane abuts against the buffer assembly 7, and the resulting impact force causes the collision head 702 to slide inside the tube 701. Under the action of the spring 703, the impact force is buffered and offset. When the spring 703 is compressed to its limit, it breaks through the welding point of the unloading plate 704 to further offset the impact force. At the same time, the spring 703 generates a buffering effect again. Under the buffering effect of multiple unloading plates 704 and springs 703, the impact force on the gantry crane is offset. Through the cooperation of the buffer assembly 7 and the buffer, the damage to the gantry crane, the damage to falling goods, and personal injury caused by the collision can be effectively prevented.

[0032] Specifically, the box 1 is equipped with a reinforcing component 6 to improve the strength of the box 1. The reinforcing component 6 includes a top plate 601 fixed to the inside of the box 1 and a connecting beam 602 for fixing the top plate 601 to the support beam 5. The top plate 601 corresponds to the buffer component 7.

[0033] Understandably, in order to improve the service life of the crash barrier, a reinforcing component 6 corresponding to the buffer component 7 is installed inside the box 1. When the gantry crane collides with the surface of the buffer component 7, the resulting impact force acts on the surface of the box 1. The impact force is transmitted to the surface of the support beam 5 through the top plate 601 and the connecting beam 602. The impact force is then effectively dispersed to the entire surface of the crash barrier through the support beam 5, thereby improving the service life of the crash barrier.

[0034] In this utility model, before erecting the gantry crane, the gantry crane foundation 2 and the expanded foundation 3 are both bound together with steel bars, and a position for the box body 1 is reserved at the tail end. Support beams 5 and reinforcing ribs 8 are welded obliquely inside the box body 1. Simultaneously, the top plate 601 and connecting beam 602 are welded and fixed, and the side plates 101 are welded and fixed. Then, the box body 1 is placed in the reserved position, and the gantry crane foundation 2 and the expanded foundation 3 are poured using formwork. Concrete is also poured into the box body 1. After pouring, it is vibrated. After complete solidification, the cover plate 102 is welded to the bottom of the box body 1 for sealing. A flange is welded to the side, and the buffer assembly 7 is fixedly installed through the flange. When the gantry crane collides with the surface of the housing 1, the buffer at the end of the gantry crane abuts against the buffer assembly 7. The resulting impact force causes the collision head 702 to slide inside the tube 701. The impact force on the gantry crane is offset by the buffering effect of multiple unloading plates 704 and springs 703. With the action of the reinforcing assembly 6 and the embedded rod 4, the impact force is dispersed to the entire anti-collision block, improving its service life. The cooperation between the buffer assembly 7 and the buffer can effectively prevent damage to the gantry crane, damage to falling goods, and personal injury caused by collision.
