Description

Technical Field

[0001] The utility model relates to the technical field of gantry cranes, in particular to a movable roller installation structure of a gantry crane. Background Art

[0002] The gantry crane's rollers are a crucial component, carrying the entire crane's weight and enabling it to move smoothly along its tracks. As the contact point between the gantry crane and the tracks, the rollers must possess sufficient load-bearing capacity to ensure stable operation under various operating conditions. Gantry crane rollers are widely used in various industrial applications, such as construction sites, ports, and warehouse logistics. In these environments, gantry cranes frequently move and lift cargo, so the quality and performance of the rollers are directly related to the crane's operating efficiency and safety.

[0003] When installing the existing rollers, it is necessary to use gaskets to adjust the distance between the rollers, so that the rollers can be easily clamped on the surface of the I-beam. However, when installing the existing rollers, multiple gaskets are needed to adjust the positions of the rollers to the appropriate positions. This is not only cumbersome, but also reduces the installation efficiency of the rollers by the workers. In addition, the thickness of the gaskets is mostly different, and when selecting the gaskets, it is also necessary to select gaskets that match them. When the positions of the rollers on both sides are not installed correspondingly, it is easy to cause uneven force, which reduces the applicability of the structure. Utility Model Content

[0004] The purpose of the utility model is to provide a movable roller installation structure for a gantry crane to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a mobile roller mounting structure for a gantry crane, comprising a mounting plate and positioning threaded rods fixed at two locations on both sides thereof, and further comprising:

[0006] A mounting bracket slides on the surface of the positioning threaded rod, rollers are installed at two locations on one side of the mounting bracket, support brackets are fixedly connected at two locations on both sides of the mounting plate surface, a fixing plate is slidably connected to the inner cavity of the support bracket, and a support ring is fixedly connected to one end of the fixing plate;

[0007] Fixed grooves are provided on both sides of the bottom of the mounting plate, and an adjustment mechanism is installed in the inner cavity of the fixed grooves. A guide plate is fixedly connected to the surface of the mounting plate, and a guide shell is slidably connected to the surface of the guide plate.

[0008] Preferably, the adjustment mechanism includes a first bevel gear rotating on the inner wall of the fixing groove and a second bevel gear meshing on one side thereof, and also includes a bidirectional threaded rod fixed on the surface of the second bevel gear and a sleeve threadedly connected to both sides of its surface.

[0009] Preferably, a mounting seat is fixedly connected to the bottom of the first bevel gear, and a surface of the mounting seat is rotatably connected to the inner wall of the fixing groove.

[0010] Preferably, the surface of the guide plate is provided with scale lines, and the scale lines are used in conjunction with the guide shell.

[0011] Preferably, one end of the guide plate is fixedly connected to a blocking plate, and the diameter of the blocking plate is greater than the width of the guide plate.

[0012] Preferably, the inner diameter of the support ring is larger than the outer diameter of the positioning threaded rod, and the support ring is used in conjunction with the positioning threaded rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model can adjust the position of the fixing plate and the support ring through the cooperation of the adjustment mechanism, thereby changing the support point of the mounting frame, thereby adjusting the distance between the two rollers, which is not only more convenient, but also improves the installation efficiency of the rollers. At the same time, the two support rings can be moved toward or oppositely at the same time, so that there will not be a large gap in the positions of the two rollers, avoiding the situation that the roller positions are not accurate enough and the force is not uniform, effectively improving the applicability of the structure, and solving the problems of poor installation efficiency and poor applicability of the existing structure when in use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4The figure shows a movable roller mounting structure of a gantry crane, comprising a mounting plate 1, two places on both sides of the mounting plate 1 are fixedly connected with a positioning threaded rod 2, the surface of the positioning threaded rod 2 is slidably connected with a mounting bracket 3, two places on one side of the mounting bracket 3 are installed with rollers 4, under this action, the mounting bracket 3 can be squeezed with the cooperation of the nut, so as to facilitate the fixation of the mounting bracket 3 and the roller 4, two places on both sides of the surface of the mounting plate 1 are fixedly connected with a supporting bracket 5, the supporting bracket 5 can support one side of the mounting bracket 3, so as to form an extrusion state for the mounting bracket 3 with the cooperation of the nut, the inner cavity of the supporting bracket 5 is slidably connected with a fixing plate 6, and one end of the fixing plate 6 is fixedly connected with a supporting ring 7, under this action, By adjusting the position of the fixing plate 6, the support ring 7 supports one side of the mounting frame 3, so that it is more convenient for the staff to adjust the position of the rollers 4 on both sides. The inner diameter of the support ring 7 is larger than the outer diameter of the positioning threaded rod 2. The support ring 7 is used in conjunction with the positioning threaded rod 2. Under this function, when the staff cooperates with the positioning threaded rod 2 to limit the mounting frame 3, the support ring 7 will not affect the normal use of the positioning threaded rod 2. Fixed grooves 14 are provided on both sides of the bottom of the mounting plate 1, and the inner cavity of the fixed groove 14 is installed with an adjustment mechanism 8. Under the action of the adjustment mechanism 8, the support ring 7 can be moved by cooperating with the fixing plate 6, so that the staff can adjust the support ring 7 The support ring 7 can be adjusted more conveniently, and the support ring 7 can be limited after it is moved, so that the support ring 7 can not move arbitrarily after it is moved and affect the positioning effect of the mounting bracket 3. The surface of the mounting plate 1 is fixedly connected with a guide plate 9, and the surface of the guide plate 9 is slidably connected with a guide shell 10. One side of the guide shell 10 is fixedly connected with the surface of the upper fixed plate 6. Under this action, the fixing plate 6 can be guided when it moves by the cooperation of the guide plate 9 and the guide shell 10, so that the fixing plate 6 can be more stable when it moves, so that the position of the fixing plate 6 can not be adjusted and the positioning effect of the support ring 7 on the mounting bracket 3 can be affected. One end of the guide plate 9 is fixedly connected with a blocking plate 12 to block The diameter of the plate 12 is larger than the width of the guide plate 9. Under this action, the guide shell 10 can be blocked by the blocking plate 12, so that the guide shell 10 will not detach from the surface of the guide plate 9, avoiding the guide shell 10 from detaching and affecting the normal use of the fixed plate 6. The surface of the guide plate 9 is provided with a scale line 11, and the scale line 11 is used in conjunction with the guide shell 10. Under this action, when the adjustment mechanism 8 adjusts the position of the support rings 7 on both sides, the position of the support ring 7 can be made more accurate with the cooperation of the scale line 11, thereby facilitating the subsequent staff to adjust the position of the roller 4 on the other side, thereby improving the accuracy of the position of the roller 4, and effectively improving the efficiency of the structure in adjusting the position of the roller 4.

[0022] The adjustment mechanism 8 includes a first bevel gear 81 that rotates on the inner wall of the fixing groove 14, and a second bevel gear 82 is engaged with one side of the mounting plate 1. The surface of the second bevel gear 82 is fixedly connected to a two-way threaded rod 83, and both sides of the surface of the two-way threaded rod 83 are threadedly connected to a sleeve 84. One side of the sleeve 84 is fixedly connected to the surface of the lower fixing plate 6. Under this action, the second bevel gear 82 can be moved in opposite directions at the same time by rotating the first bevel gear 81 through the two-way threaded rod 83, thereby changing the mounting position under the cooperation of the fixing plate 6 and the support ring 7. The blocking position of the frame 3 provides power for the position adjustment between the two rollers 4, which is not only convenient, but also can be adjusted on both sides at the same time, so that the position of the roller 4 will not have a large position deviation, effectively improving the uniformity of the force applied to the roller 4 during use. The bottom of the first bevel gear 81 is fixedly connected to the mounting seat 13, and the surface of the mounting seat 13 is rotatably connected to the inner wall of the fixing groove 14. Under this action, the cooperation of the mounting seat 13 can provide an effective force point for the staff to rotate the first bevel gear 81, thereby making it more convenient for the first bevel gear 81 to rotate.

[0023] Working principle: First, adjust the position of the roller 4 according to the size of the I-beam, and then the staff rotates the mounting seat 13 to make the first bevel gear 81 drive the bidirectional threaded rod 83 to rotate through the second bevel gear 82, so that the sleeve 84 can drive the fixed plate 6 to move under the action of its surface thread, and then the fixed plate 6 drives the support ring 7 to move, and adjust the distance between the two support rings 7. When the position of the support ring 7 is adjusted to match the I-beam, the staff connects the mounting frame 3 and the positioning threaded rod 2 to each other, and then uses the nut to squeeze the mounting frame 3. When the nut squeezes the mounting frame 3, the support ring 7 will also block the mounting frame 3, so that the mounting frame 3 is clamped and limited under the cooperation of the support ring 7 and the nut, so as to install the roller 4.
