Abstract
Description
Technical Field
[0001] This utility model relates to the field of track installation structure technology, and in particular to a track reinforcement device for gantry cranes. Background Technology
[0002] Gantry cranes, as important material handling equipment, are widely used in the manufacturing and logistics industries. The rails beneath them are one of the key components ensuring smooth operation and enhancing safety. However, existing rail connections mainly rely on bolts and external fixing components. While this method can meet basic usage requirements to a certain extent, its stability and safety still need improvement. Especially during the lifting of heavy objects, the stability of the rails directly affects the safety performance of the entire system and its maximum load capacity.
[0003] Existing fixing methods generally have two problems: First, bolt fixing alone may loosen due to vibration and fatigue during long-term use. If the positioning and maintenance are not in place, it will affect the stability of the entire structure and may even pose a safety hazard. Second, the connection strength and impact resistance of the external fixing components themselves are often limited. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gantry crane track reinforcement device. Based on bolts, which are external fixing components, a new reinforcement structure is added to provide a more reliable fixing solution.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A gantry crane track reinforcement device includes a concrete base and a track. The concrete base has a groove with a length greater than that of the track along its length. Track positioning components are installed at equal intervals along the length of the groove. Reinforcing concrete is poured into the groove.
[0007] The track bottom has several positioning slots that are equidistant from each other on both sides and along the length direction;
[0008] The track positioning assembly includes a cast-in-place fixing structure and a docking bending fixing part. The docking bending fixing part is docked with the positioning groove, and after being pressed, it bends towards the outside of the bottom of the track and is fixed to the concrete base by bolts.
[0009] Furthermore, the thickness of the reinforced concrete pouring section is reserved for the rail bottom groove into which the rail bottom is inserted.
[0010] Furthermore, the positioning groove penetrates the upper and lower end faces of the track bottom, and the bottom of the positioning groove is provided with a guide groove. The guide groove is larger than the positioning groove and has a funnel structure with the outer side facing the inner side.
[0011] Furthermore, the casting fixing structure includes a vertical part and a connecting part, with two vertical parts and two connecting parts. The connecting parts are staggered between the two vertical parts. The bottom of the vertical part is provided with a base plate, and the periphery of the vertical part is provided with a contact plate parallel to the casting height of the reinforced concrete part.
[0012] Furthermore, the casting fixing structure is made of steel.
[0013] Furthermore, the base plate is bolted into the pit and reinforced with concrete, and the contact plate is fitted to the bottom of the track.
[0014] Furthermore, the docking bending fixing part is a vertical part above the contact plate, and the two docking bending fixing parts have arc-shaped bending grooves at their far ends.
[0015] Furthermore, the number of track positioning components is the same as the number of equally spaced positioning slots and they cooperate with each other.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. By setting up track positioning components in the concrete base pit and pouring reinforced concrete, a multi-fixed structure is formed. The docking and bending fixing part of the track positioning component is precisely docked with the positioning groove at the bottom of the track. After bending, it is firmly fixed to the concrete base with bolts. This effectively avoids the loosening problem caused by long-term vibration and fatigue due to bolt fixation alone. It greatly enhances the connection stability between the track and the concrete base, ensures the stability of the track during the operation of the gantry crane, provides reliable protection for the lifting of heavy objects, and improves the safety performance and maximum load capacity of the entire system.
[0018] 2. The casting and fixing structure of the track positioning component is made of steel, which has high strength and toughness. Its unique structural design includes two vertical parts that are connected by a connecting part. The bottom of the vertical part is set with a base plate and is installed in the pit with bolts. The outer perimeter is set with a contact plate parallel to the casting height of the reinforced concrete part, and the contact plate is in close contact with the bottom of the track. This allows the entire reinforcement device to better distribute and withstand the impact force generated during the operation of the crane, effectively overcoming the problem of limited connection strength and impact resistance of existing external fixing components, and further improving the reliability and service life of the track.
[0019] 3. The thickness of the reinforced concrete section is reserved with a rail bottom groove for the rail bottom to be inserted. This design allows the rail to be stably embedded in the reinforced concrete section and cooperate with the rail positioning components to form an organic whole. At the same time, the overall structure of the reinforcement device is reasonable and does not change the original basic layout and installation method of the gantry crane rail.

[0035] Example 1
[0036] like Figure 1-4 As shown, this utility model provides a technical solution: a gantry crane track reinforcement device, including a concrete base 1 and a track 2. The concrete base 1 has a groove 3 with a length greater than that of the track 2 reserved along its length direction. The groove 3 provides sufficient space for subsequent installation of track positioning components 4 and pouring of reinforcement concrete parts 5. Track positioning components 4 are installed at equal intervals along the length direction in the groove 3. These track positioning components 4 are evenly distributed and can effectively fix the track 2 from multiple points to ensure that the track 2 is subjected to uniform force. The reinforcement concrete parts 5 are poured in the groove 3, which further enhances the stability of the entire structure and tightly integrates the track positioning components 4 with the concrete base 1 into a whole.
[0037] The bottom of the track 2 has several positioning grooves 21 that are equidistant from each other on both sides and along the length direction. The positioning grooves 21 provide a precise docking position for the docking bending and fixing part 42 of the track positioning component 4, ensuring the accuracy of the installation of the track 2.
[0038] The track positioning component 4 includes a cast-in-place fixing frame 41 and a docking bending fixing part 42. The docking bending fixing part 42 docks with the positioning groove 21, and after applying pressure, it bends towards the outside of the bottom of the track 2 and is fixed to the concrete base 1 by bolts 6. This design makes the connection between the track 2 and the concrete base 1 more secure and effectively avoids the problem of easy loosening of the traditional bolt fixing method.
[0039] Example 2
[0040] like Figure 1-4 As shown, the thickness of the reinforced concrete part 5 is reserved for the rail bottom groove 22 into which the rail bottom of the track 2 is inserted. During the pouring process, a mold is used to reserve the rail bottom groove 22. The use of the mold can precisely control the size and shape of the rail bottom groove 22, ensuring that the track 2 can be accurately inserted, further improving the accuracy and stability of the track 2 installation.
[0041] The positioning groove 21 penetrates the upper and lower end faces of the bottom of the track 2. The bottom of the positioning groove 21 is provided with a guide groove 211. The guide groove 211 is larger than the positioning groove 21 and has a funnel structure with the outer side facing the inner side. It is used to guide the mating bending fixing part 42 to abut. During the installation process, the guide groove 211 enables the mating bending fixing part 42 to enter the positioning groove 21 quickly and accurately, which improves the installation efficiency and reduces the installation error.
[0042] The casting-fixed structure 41 includes two vertical parts 411 and two connecting parts 412. The connecting parts 412 are staggered between the two vertical parts 411. This staggered connection structure increases the overall strength and stability of the casting-fixed structure 41. The bottom of the vertical part 411 is provided with a base plate 413. The periphery of the vertical part 411 is provided with a contact plate 414 parallel to the casting height of the reinforced concrete part 5. The base plate 413 is installed in the pit 3 with bolts, providing a stable support foundation for the casting-fixed structure 41. The contact plate 414 fits against the bottom of the rail 2, which can increase the contact area with the rail 2, disperse the pressure on the rail 2, and improve the reinforcement effect.
[0043] The casting and fixing structure 41 is made of steel, which has high strength, high toughness and good corrosion resistance, ensuring that the casting and fixing structure 41 will not deform or be damaged during long-term use, and providing a lasting reinforcement for the track 2.
[0044] The docking bending fixing part 42 is the vertical part 411 above the contact plate 414. The two docking bending fixing parts 42 have arc-shaped bending grooves 421 at their far ends, which provide bending points when bending with tools, reducing the difficulty of bending. During installation, workers can use special tools to easily bend the docking bending fixing part 42 along the arc-shaped bending grooves 421 to make it fit with the bottom of the track 2 and fix it to the concrete base 1 with bolts 6.
[0045] The number of track positioning components 4 is the same as the number of equidistant positioning slots 21, and they cooperate with each other. The installation position of the track positioning components 4 needs to be strictly determined before the reinforced concrete part 5 is poured to ensure that the positioning slots 21 cooperate with the track positioning components 4. Precise positioning can ensure the straightness and stability of the track 2 after installation, avoid problems such as track deviation and twisting, and thus ensure the normal operation of the gantry crane.
[0046] The working process of this utility model is as follows: When using a gantry crane track reinforcement device, firstly, according to the length of the track 2 and the design requirements, a pit 3 with a length greater than that of the track 2 is reserved along the length direction when the concrete base 1 is poured, and the bottom and sides of the pit 3 are leveled to ensure that they meet the installation requirements.
[0047] Following the pre-designed locations, the casting and fixing structure 41 of the track positioning component 4 is installed in the pit 3; the base plate 413 is firmly installed in the pit 3 with bolts to ensure that the position of the casting and fixing structure 41 is accurate and stable.
[0048] Then, reinforced concrete 5 is poured into the pit 3, so that the reinforced concrete 5 fully fills the gap in the pit 3 and is tightly connected with the contact plate 414 of the fixed structure 41. During the pouring process, attention should be paid to vibration and compaction to ensure the quality of the reinforced concrete 5. After the reinforced concrete 5 has solidified and hardened.
[0049] Because a mold is used to pre-leave a rail bottom groove 22 in the pit 3 for the rail bottom of the rail 2 to be inserted, it prepares for the subsequent installation of the rail 2;
[0050] Then, the track 2 is slowly placed into the pit 3, so that the bottom of the track 2 is inserted into the bottom groove 22. During the placement process, the guide groove 211 at the bottom of the positioning groove 21 is used to guide the docking bending fixing part 42 of the track positioning component 4 to accurately abut against the positioning groove 21.
[0051] After the track 2 is placed in place, use a special tool to apply pressure to the butt bending fixing part 42, so that it bends along the arc bending groove 421 toward the outside of the bottom of the track 2 until the butt bending fixing part 42 fits against the bottom of the track 2. Then use bolts 6 to firmly fix the bent butt bending fixing part 42 to the concrete base 1.
[0052] The entire gantry crane track reinforcement device is inspected and tested to ensure that the straightness and stability of track 2 meet the requirements before it can be put into use.
[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
