A track positioning mechanism for a gantry crane

Abstract

This utility model discloses a rail positioning mechanism for a gantry crane, including an iron pad. By optimizing the rail fixing structure design, this utility model significantly improves the reliability and stability of rail fixing. The positioning channel formed by two positioning plates can accurately limit the rail position, ensuring the overall geometric accuracy of the rail after installation. When the first positioning mechanism is installed on the iron pad, it can achieve initial positioning and fixing of the rail, effectively resisting the displacement risk caused by foundation vibration. Furthermore, after the second positioning mechanism is installed on the positioning plate, it forms secondary positioning and fixing, further enhancing the constraint on the rail. This dual positioning and fixing structure can effectively resist alternating loads, impact vibrations, and environmental factors, reducing irregular changes in rail spacing, avoiding poor contact between wheels and rails and rail wear, extending the service life of wheels and rails, reducing maintenance costs and downtime, and improving the operational safety and efficiency of the gantry crane.

Description

Technical Field

[0001] This utility model relates to the field of track positioning technology for gantry cranes, specifically to a track positioning mechanism for gantry cranes. Background Technology

[0002] In the field of rail positioning and fixing technology, the industry currently generally uses traditional fixing structures such as pressure plates and fasteners to constrain and fix rails. These devices use mechanical clamping.

[0003] However, existing track positioning and fixing structures have gradually revealed problems with poor fixing performance. Specifically, under the long-term effects of alternating loads, impact vibrations, and environmental factors generated during crane movement, fixing components such as pressure plates and fasteners are prone to loosening and deformation. This can lead to irregular changes in the rail spacing. The unstable changes in rail spacing can seriously affect the contact state between the crane wheels and the rails, resulting in poor contact and rail wear. This will affect the service life of the wheels and rails, increase equipment maintenance costs and downtime. Therefore, we need to propose a track positioning mechanism for gantry cranes. Utility Model Content

[0004] The purpose of this utility model is to provide a track positioning mechanism for a gantry crane, so as to solve the problem mentioned in the background art that the track positioning and fixing effect is poor, which affects the contact state between the crane wheels and the track, resulting in poor contact between the crane wheels and the track and causing track wear, which affects the service life of the wheels and rails, and increases the maintenance cost and downtime of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The first positioning mechanism includes a first mounting plate, a second spiral rail spike, and a second locking nut. The first mounting plate is located in the clearance channel. The bottom of the first mounting plate is provided with a pressing part. The pressing part at the bottom of the first mounting plate presses against the base of the rail. The second spiral rail spike passes through the first mounting plate and the iron pad plate. The second locking nut is threaded onto the second spiral rail spike.

[0008] Preferably, the second positioning mechanism includes a connecting block and a positioning block. The connecting block is fixedly connected to both sides of the first mounting plate, and the bottom of the connecting block abuts against the base of the rail. The positioning block is fixedly connected to the bottom of the connecting block. The positioning plate has a positioning groove that matches the positioning block, and the positioning block is inserted into the positioning groove.

[0009] Preferably, the bottom of the connecting block is integrally formed with a clamping block, which abuts against the side of the base of the rail.

[0010] Preferably, the positioning plate has a mounting platform for the connecting block to avoid, the top of the mounting platform is fixedly connected to a threaded seat, and the side of the connecting block is fixedly connected to a second mounting plate corresponding to the threaded seat.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A track positioning mechanism for a gantry crane includes: an iron pad 1, on which two sets of positioning plates 2 are symmetrically fixedly connected, with a positioning channel 3 between the two sets of positioning plates 2; a steel rail 4 placed in the positioning channel 3 on the top of the iron pad 1; a first positioning mechanism for securing the steel rail 4, installed on the top of the iron pad 1; and a second positioning mechanism for securing the steel rail 4, installed on the positioning plates 2, wherein the steel rail 4 is fixedly installed on the top of the iron pad 1 through the first positioning mechanism and the second positioning mechanism.

[0024] It should be noted that by setting the positioning plate 2, the position of the rail can be precisely limited, ensuring the overall geometric accuracy of the rail after installation, and laying the foundation for the stable operation of the gantry crane.

[0025] In an optional embodiment: such as Figures 1 to 5 As shown, both sets of positioning plates 2 are provided with clearance channels 10. The first positioning mechanism includes a first mounting plate 7, a second spiral rail spike 8 and a second locking nut 9. The first mounting plate 7 is located in the clearance channel 10. The bottom of the first mounting plate 7 is provided with a pressing part. The pressing part at the bottom of the first mounting plate 7 presses against the base of the rail 4. The second spiral rail spike 8 passes through the first mounting plate 7 and the iron pad 1. The second locking nut 9 is threaded onto the second spiral rail spike 8.

[0026] It should be noted that by setting up the clearance channel 10, not only is installation space provided for the first mounting plate 7, but the lateral displacement of the first mounting plate 7 is also restricted by the geometric boundary of the channel, which plays a role in accurately positioning the first mounting plate 7, ensuring that the first mounting plate 7 can stably press against the rail base, and ensuring the effective transmission of vertical clamping force.

[0027] Furthermore, the second spiral rail spike 8, in conjunction with the second locking nut 9, serves to install the iron pad 1, which can firmly fix the iron pad 1 to the concrete foundation, ensuring the stability of the iron pad as the track installation benchmark, avoiding displacement of the iron pad due to foundation settlement or vibration, and providing a reliable foundation for the subsequent precise positioning of the rail.

[0028] In an optional embodiment: such as Figures 3 to 5 As shown, the second positioning mechanism includes a connecting block 12 and a positioning block 14. The connecting block 12 is fixedly connected to both sides of the first mounting plate 7, and the bottom of the connecting block 12 is pressed against the base of the rail 4. The positioning block 14 is fixedly connected to the bottom of the connecting block 12. The positioning plate 2 has a positioning groove 15 that is compatible with the positioning block 14, and the positioning block 14 is inserted into the positioning groove 15.

[0029] It should be noted that by cooperating with the positioning block 14 and the positioning groove 15, the lateral movement of the connecting block 12 and the first mounting plate 7 is further restricted, forming a lateral positioning constraint, so that the first mounting plate 7 and the positioning plate 2 form a rigid connection relationship, avoiding the first mounting plate 7 from shifting when subjected to force, thereby enhancing the positioning stability of the first positioning mechanism.

[0030] In an optional embodiment: such as Figures 4 to 5 As shown, the bottom of the connecting block 12 is integrally formed with a clamping block 19, which clamps against the side of the base of the rail 4.

[0031] It should be noted that by setting the clamping block 19, a lateral clamping force is applied from the side of the rail base 4, which directly constrains the lateral displacement of the rail and effectively prevents the rail from tilting or deviating during operation.

[0032] In an optional embodiment: such as Figure 3 As shown, the positioning plate 2 has a mounting platform 13 for the connecting block 12 to avoid. A threaded seat 18 is fixedly connected to the top of the mounting platform 13. A second mounting plate 16 corresponding to the threaded seat 18 is fixedly connected to the side of the connecting block 12. The second mounting plate 16 is provided with a fixing screw 17. The threaded end of the fixing screw 17 is threaded into the threaded seat 18.

[0033] It should be noted that the mounting platform 13 provides a mounting support surface for the connecting block 12, and with the rigid connection between the fixing screw 17 and the threaded seat 18, the connecting block 12 and the positioning plate 2 are firmly fixed, which further strengthens the overall connection strength of the first mounting plate 7, the connecting block 12 and the positioning plate 2, prevents the components from loosening under long-term load, and improves the structural stability of the positioning mechanism.

[0034] In an optional embodiment: such as Figure 2 and Figure 3 As shown, the inner sides of both sets of positioning plates 2 are provided with inclined parts 11, and the base side of the rail 4 contacts the inner side of the positioning plate 2.

[0035] It should be noted that the inclined part 11 can play a guiding role during the installation of the rail, guiding the rail to fall accurately into the preset position of the positioning channel 3.

[0036] In an optional embodiment: such as Figures 1 to 3 As shown, a first spiral spike 5 is inserted into the iron pad 1, and a first locking nut 6 is threaded onto the first spiral spike 5.

[0037] It should be noted that the first spiral rail spike 5 and the first locking nut 6 work together to install the iron pad 1, which can firmly fix the iron pad 1 to the concrete foundation, ensure the stability of the iron pad as the track installation benchmark, avoid the iron pad displacement caused by foundation settlement or vibration, and provide a reliable foundation for the subsequent accurate positioning of the rail.

[0038] The usage process of this utility model is as follows: the iron pad 1 is fixed to the concrete by the first spiral rail spike 5 and the first locking nut 6, the rail 4 is placed in the positioning channel 3, and the side of the base of the rail 4 contacts the inner side of the positioning plate 2, which can accurately limit the position of the rail and ensure the geometric accuracy of the rail after installation.

[0039] After placing the first mounting plate 7 on top of the iron pad 1, align the first mounting plate 7 with the clearance channel 10. By pushing the first mounting plate 7, the first mounting plate 7 moves into the clearance channel 10, and the bottom of the first mounting plate 7 abuts against the base of the rail 4. After the second spiral rail spike 8 passes through the first mounting plate 7 and the iron pad 1, it is installed in the concrete. The second locking nut 9 is threaded onto the second spiral rail spike 8, thereby fixing the first mounting plate 7 on top of the iron pad 1. The first mounting plate 7 can be used to initially position and fix the rail 4, effectively resisting the displacement risk caused by foundation vibration.

[0040] Furthermore, when the first mounting plate 7 is moved into the clearance channel 10, the positioning block 14 is inserted into the positioning groove 15, and the bottom of the connecting block 12 is pressed against the base of the rail 4. The fixing screw 17 on the second mounting plate 16 is threaded into the threaded seat 18, thereby enabling secondary positioning and fixing of the rail 4, further enhancing the constraint capability of the rail 4. The dual positioning and fixing structure can effectively resist the influence of alternating loads, impact vibrations and environmental factors, reduce irregular changes in the spacing of the rail 4, avoid poor contact between the wheel and the rail and rail biting, extend the service life of the wheel and rail 4, reduce maintenance costs and downtime, and improve the operating safety and efficiency of the gantry crane.

[0041] 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.
