AI Technical Summary
During the bridge shell casting process, when using a gantry crane to transport sand boxes, the sand boxes are prone to shaking or overturning due to inertia, resulting in unstable transport.
The design employs a combination of gantry crane, integrated frame, first integrated base, and second integrated base. Balanced lifting is achieved through lifting rings and hooks. The integrated frame is triangular in shape to ensure the stability of the sand box during transportation.
This improves the transport stability of the bridge housing casting sand box, avoids shaking and overturning of the sand box, and ensures the safety and accuracy of the transport process.

[0015] 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.
[0016] This utility model provides, for example Figures 1-4 The image shows a bridge shell casting sand box conveying device.
[0017] Example 1: Includes a gantry crane 1, a mounting frame 21, a tripod 22, a lifting ring 23, a first integrated base 3, and a second integrated base 4. Hooks are symmetrically arranged on the gantry crane 1. The gantry crane 1 is existing equipment and will not be described in detail here. The tripod 22 is fixedly connected to the top of the mounting frame 21, and the lifting ring 23 is fixedly connected to the top of the tripod 22. The lifting ring 23 is hooked onto the hooks. Figure 2As shown, when the lifting ring 23 is hooked onto the hook on the gantry crane 1, and the first integrated seat 3 and the two second integrated seats 4 in the mounting frame 21 are connected to the three shafts on the side of the bridge shell casting sand box, the force balance during the lifting and transportation of the bridge shell casting sand box can be improved. The mounting frame 21, the tripod 22, and the lifting ring 23 can form an integrated frame. The integrated frame is hooked onto the hook, and the integrated frame as a whole is triangular in shape. The triangular fixed point of the integrated frame is connected to the hook. The first integrated seat 3 is fixedly installed in the middle of the mounting frame 21, and the second integrated seats 4 are fixed. Installed on the side of the mounting frame 21, the first integrated seat 3 and the second integrated seat 4 are used to dock with the bridge shell casting sand box. The first integrated seat 3 and the two second integrated seats 4 are on a straight line, that is, on the horizontal line of the bottom of the integrated frame as a whole. Therefore, when it transports the bridge shell casting sand box, it can improve the stability of the bridge shell casting sand box. The gantry crane 1, the integrated frame, the first integrated seat 3 and the two second integrated seats 4 are suitable for bridge shell casting sand boxes with three shafts, and the three shafts are on a straight line and are symmetrically arranged at the center.
[0018] Example 2: Based on Example 1, the second integrated base 4 includes a support base 41, a limiting base 42, a first cavity 44, a slot 45, and a second cavity 46. The first integrated base 3 and the second integrated base 4 have the same structure, with the first integrated base 3 centrally located and the two second integrated bases 4 symmetrically arranged on the sides of the first integrated base 3. The support base 41 is fixedly installed at the bottom of the inner cavity of the mounting frame 21. The limiting base 42 is slidably disposed on the top of the support base 41. A connecting collar 43 is symmetrically fixedly connected to the bottom of the limiting base 42. The first cavity 44 is opened at the bottom of the limiting base 42. A groove 45 is formed on the side of the top of the bearing seat 41, and the groove 45 corresponds to the connecting collar 43. A second cavity 46 is formed on the top of the bearing seat 41, and a brake pad 47 is fixedly connected to the bottom of the inner wall of the second cavity 46. When the shaft on the side of the bridge housing casting sand box slides into the connecting collar 43, and the gantry crane 1 drives the integrated frame to rise, under the gravity of the bridge housing casting sand box, the limiting seat 42 moves toward the bearing seat 41, and the shaft on the side of the bridge housing casting sand box fits into the brake pad 47 on the bearing seat 41, thereby braking the shaft and improving the stability of the bridge housing casting sand box docking.
[0019] Furthermore, the second integrated seat 4 also includes a sliding hole, a fixing bolt 48, a slider 49, and a sliding groove. The sliding hole is opened at the bottom of the mounting frame 21 and has a certain length. The outer wall of the fixing bolt 48 is slidably sleeved with the inner cavity of the sliding hole. The top of the outer wall of the fixing bolt 48 is threadedly connected to the bearing seat 41. Loosening the fixing bolt 48 allows the bearing seat 41 to slide inside the mounting frame 21, thereby changing the distance between the second integrated seat 4 and the first integrated seat 3. The slider 49 is fixedly connected to the top of the inner wall of the mounting frame 21. The sliding groove is opened at the top of the limiting seat 42. The outer wall of the slider 49 is slidably sleeved with the inner cavity of the sliding groove. The slider 49 can guide and limit the limiting seat 42, improving the stability of the limiting seat 42 operation.
[0020] Furthermore, the second integrated base 4 also includes a support spring 410, a guide post 411, a fixing collar 412, and a limiting block 413. The top of the bearing base 41 has an installation groove, and the support spring 410 is slidably fitted inside the installation groove. The top of the guide post 411 is fixedly connected to the limiting seat 42. The guide post 411 is located on top of the support spring 410, and the guide post 411 can guide and limit the limiting seat 42, allowing the limiting seat 42 to slide only up and down relative to the bearing base 41. The slider 49 has a certain height; when the bottom of the limiting seat 42 is in contact with the bearing base 41, the slider 49 will not separate from the groove. The end of the slider 49 has a notch, allowing the fixing bolt 48 to be removed, so that the bearing base 41 and the limiting seat 42 can slide to the outermost side of the mounting frame 21. This allows the limiting seat 42 to separate from the slider 49, enabling the disassembly and maintenance of the bearing seat 41 and the limiting seat 42. The fixing collar 412 is fixedly sleeved on the top of the inner cavity of the mounting groove, and the outer wall of the guide post 411 is slidably sleeved with the fixing collar 412. The limiting block 413 is fixedly connected to the bottom of the guide post 411, and the bottom of the limiting block 413 is pressed against the support spring 410. The support spring 410 can provide an elastic restoring force to the limiting seat 42 through the limiting block 413 and the guide post 411, so that when the shaft is separated from it, the limiting seat 42 can rise and return to its original position. Moreover, the elastic force of the support spring 410 acting on the limiting seat 42 is greater than the weight of the limiting seat 42 and much less than the weight of the bridge housing casting sand box, thus preventing the limiting seat 42 from failing to descend and dock with the bearing seat 41 when the bridge housing casting sand box is lifted.
[0021] 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.
