Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of gantry cranes, and in particular relates to a track reinforcement structure for gantry cranes. Background Technology
[0002] Since gantry cranes are mostly used outdoors, it is necessary to reinforce the rails to ensure that the entire gantry crane can operate stably on the rails. However, some existing rail reinforcement structures require coordination with the rails during the laying process for installation. For example, the gantry crane rail reinforcement device disclosed in utility model publication number CN216687139U requires the vertical plate to be fixedly installed on the bottom surface of the rails during use. This is not suitable for reinforcing existing rails, and therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content
[0003] The purpose of this invention is to provide a track reinforcement structure for a gantry crane to solve the problems mentioned in the background art.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows:
[0005] A track reinforcement structure for a gantry crane includes vertically distributed fixing blocks, with vertically distributed positioning screws slidably connected to the fixing blocks. The top of the positioning screws is located outside the fixing blocks and threaded with a locking ring. The bottom of the positioning screws is coaxially fixedly connected to a limit block, and the bottom surface of the limit block is coaxially fixedly connected to vertically distributed positioning pins with pointed bottom ends.
[0006] A reinforcing block, which is integral with the fixing block, is fixedly connected to the top of one side of the fixing block. The bottom surface of the reinforcing block is an upward sloping surface, and auxiliary clamping components are installed on the side of the reinforcing block.
[0007] Furthermore, the auxiliary clamping component includes an extension block arranged parallel to the inclined surface of the reinforcing block. The extension block is fixedly connected to the reinforcing block, and a clamping bolt that is perpendicular to and passes through the extension block is threadedly connected to the side of the extension block away from the reinforcing block. The head of the clamping bolt is inclined upward, and a connecting sleeve is threadedly connected to the screw end of the clamping bolt.
[0008] Furthermore, the auxiliary clamping components are installed on both the front and back sides of the reinforcing block.
[0009] Furthermore, the positioning screw has two locking rings.
[0010] Furthermore, the diameter of the limiting block is larger than the diameter of the positioning screw and the positioning pin. The positioning screw is slidably connected to the fixing block through a first through hole vertically opened on the fixing block. A second through hole is opened on the bottom surface of the fixing block and is coaxially arranged with the first through hole. The diameter of the second through hole is adapted to the diameter of the limiting block and is larger than the diameter of the first through hole. The height of the second through hole is greater than the vertical distance between the top surface of the limiting block and the bottom end of the positioning pin.
[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows:
[0012] When this utility model is used, when it is fastened to the bottom of the track, the inclined surface of the reinforcing block abuts against the inclined surface of the bottom of the track, and the side of the fixing block near the reinforcing block abuts against the side edge of the bottom of the track. After manually pressing the reinforcing block and the fixing block, a tool such as a hammer can be used to drive the positioning nail into the ground until the limiting block is pressed against the ground, thus fixing the position of the positioning screw. Then, by rotating the locking ring on the positioning screw until the locking ring is pressed against the top surface of the fixing block, the reinforcing block can be pressed against the bottom of the track to reinforce the track. Secondly, after the reinforcing block is pressed against the bottom of the track by the locking ring, an auxiliary clamping component can be used to further press the reinforcing block against the bottom of the track to improve the reinforcement effect. Compared with the prior art, this utility model is applicable to the reinforcement of existing laid tracks. Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0019] like Figures 1 to 4 As shown, this utility model provides a track reinforcement structure for a gantry crane. Specifically, in use, this utility model consists of multiple sets, with each set of track reinforcement structures installed on both sides of the bottom of a track 8 and evenly distributed along the length of the track 8. This utility model includes vertically distributed fixing blocks 3, with vertically distributed positioning screws 4 slidably connected to the fixing blocks 3. The top of the positioning screws 4 is located outside the fixing blocks 3 and threadedly connected to a locking ring 5, which is similar to a nut in the prior art. A limit block 6 is coaxially fixedly connected to the bottom end of the positioning screws 4. Vertically distributed positioning pins 7 with pointed bottom ends are coaxially fixedly connected to the bottom surface of the limit block 6. Specifically, the positioning pins 7 have barbs. Furthermore, a reinforcement block 1, integrally formed with the fixing block 3, is fixedly connected to the top of one side of the fixing block 3. The bottom surface of the reinforcement block 1 is an upwardly inclined slope. Figure 2 As shown, the inclined surface of the reinforcing block 1 is set parallel to the inclined surface at the bottom of the track 8; an auxiliary clamping component 2 is installed on the side of the reinforcing block 1.
[0020] Specifically, when this utility model is used, when it is fastened to the bottom position of the track 8, the inclined surface of the reinforcing block 1 abuts against the inclined surface of the bottom position of the track 8, and the side of the fixing block 3 near the reinforcing block 1 abuts against the side edge of the bottom position of the track 8. Then, after manually pressing the reinforcing block 1 and the fixing block 3, a tool such as a hammer can be used to drive the positioning nail 7 into the ground until the limiting block 6 is pressed against the ground, thus fixing the position of the positioning screw 4. Then, by rotating the locking ring 5 on the positioning screw 4 until the locking ring 5 is pressed against the top surface of the fixing block 3, the reinforcing block 1 can be pressed against the bottom position of the track 8 to reinforce the track 8. Secondly, after the reinforcing block 1 is pressed against the bottom position of the track 8 by the locking ring 5, the auxiliary pressing part 2 can be used to further press the reinforcing block 1 against the bottom position of the track 8 to improve the reinforcement effect of the track 8. Compared with the prior art, this utility model can be applied to the reinforcement of the existing laid track 8.
[0021] The specific setting method of auxiliary clamping component 2 is as follows: Figures 1 to 4 As shown, the auxiliary clamping component 2 includes an extension block 21 arranged parallel to the inclined surface of the reinforcing block 1. The extension block 21 is fixedly connected to the reinforcing block 1, and a clamping bolt 22, perpendicular to and penetrating the extension block 21, is threadedly connected to the side of the extension block 21 away from the reinforcing block 1. The head of the clamping bolt 22 is inclined upward, and a connecting sleeve 23 is threadedly connected to the screw end of the clamping bolt 22. Specifically, in the initial state, the auxiliary clamping component 2 is as follows: Figure 3As shown; in use, after the locking ring 5 is used to press the bottom position of the reinforcing block 1 against the bottom position of the track 8, by rotating the connecting sleeve 23 on the clamping bolt 22, the end of the connecting sleeve 23 away from the extension block 21 can be made to abut against the inclined surface at the bottom position of the track 8. Then, the connecting sleeve 23 can be welded and fixed to the track 8 using tools such as a welding machine. Then, by rotating the clamping bolt 22 on the extension block 21 until the head of the clamping bolt 22 abuts against the extension block 21, the reinforcing block 1 can be further pressed against the bottom position of the track 8. Secondly, the auxiliary clamping parts 2 are installed on both the front and back sides of the reinforcing block 1, that is, there are two sets of auxiliary clamping parts 2 on each reinforcing block 1.
[0022] Furthermore, such as Figures 1 to 4 As shown, there are two locking rings 5 on the positioning screw 4. Specifically, when the locking rings 5 are used to press the reinforcing block 1 against the bottom position of the track 8, the interaction between the two locking rings 5 can prevent the locking rings 5 from loosening.
[0023] Furthermore, such as Figures 1 to 4 As shown, the diameter of the limiting block 6 is larger than the diameter of the positioning screw 4 and the positioning pin 7. The positioning screw 4 is slidably connected to the fixing block 3 through a first through hole vertically opened on the fixing block 3. A second through hole 31 is opened on the bottom surface of the fixing block 3, which is coaxial with the first through hole. The diameter of the second through hole 31 is adapted to the diameter of the limiting block 6 and is larger than the diameter of the first through hole. The limiting block 6 is a circular block and is slidably connected to the fixing block 3 through the second through hole 31. The height of the second through hole 31 is greater than the vertical distance between the top surface of the limiting block 6 and the bottom end of the positioning pin 7. Specifically, assuming the vertical distance between the top surface of the limiting block 6 and the bottom end of the positioning pin 7 is H1, and the height of the second through hole 31 is H2, then H2 > H1. Thus, in the initial state, it can be as follows: Figure 1 As shown, the tip of the positioning nail 7 is positioned inside the second through hole 31 to avoid injuring construction workers, and it also makes it easier to fasten the track reinforcement structure to the bottom of the track 8; when it is necessary to drive the positioning nail 7 into the ground, the locking ring 5 can be removed from the positioning screw 4 first.
