For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The utility model provides a device for preventing the finished prefabricated box beam from falling during transportation, which mainly comprises a gantry crane and an anti-falling mechanism. The gantry crane can be moved and used to lift the finished prefabricated box beam, and the anti-falling mechanism is arranged on the gantry crane and can prevent the finished prefabricated box beam from falling accidentally during lifting.

[0029] The gantry crane includes a gantry 1, a hook assembly 2, and a traveling mechanism 3 provided at the upper crossbeam of the gantry 1 and used to drive the hook assembly 2. The traveling mechanism 3 can move along the upper crossbeam of the gantry 1, and the traveling mechanism 3 includes a winch 301, on which a steel wire rope 302 is wound, and the traveling mechanism 3 is connected to the hook assembly 2 through the steel wire rope 302. The existing technology is adopted here, and the present invention will not be further described.

[0030] The hook assembly 2 includes a hook seat 201 and a hook 203 connected to the bottom of the hook seat 201. In the present utility model, a connecting seat 202 is fixedly connected to the bottom of the hook seat 201, and the hook 203 is fixed to the hook seat 201 through the connecting seat 202.

[0031] The anti-fall mechanism includes a support assembly 4, a transverse movement assembly 5 and a longitudinal limit assembly 6. The support assembly 4 is used to support and limit the hook assembly 2. When the wire rope breaks accidentally, the hook assembly 2 can be supported by the support assembly 4 to prevent the hook assembly 2 and the workpiece suspended thereon from falling. The support assembly 4 is arranged on the transverse movement assembly 5 and can move horizontally along the transverse movement assembly 5. The longitudinal limit assembly 6 is arranged on the side frame of the gantry. The longitudinal limit assembly 6 is movably connected to the transverse movement assembly 5, and when the hook assembly 2 moves with the workpiece suspended, the longitudinal limit assembly 6 can limit the longitudinal position of the transverse movement assembly 5.

[0032] The support assembly 4 includes a support seat 401, a support groove 402 with an open top is opened in the middle of the support seat 401, and a through groove 403 that penetrates the support groove 401 is opened on the lower side of the support groove 402. The upper and lower sides of the through groove 403 are both through-set, and the length of the through groove 403 is smaller than the length of the support groove 402, so that the bottom surface of the support groove 402 on the left and right sides of the through groove forms a support portion 404.

[0033] The size of the supporting groove 402 matches the size of the connecting seat 202 , so that the connecting seat 202 can be inserted into the supporting groove 401 , and the supporting portion can provide support for the connecting seat 202 .

[0034] The size of the through slot 403 is larger than that of the hook 203 , and the through slot 403 is preferably a rectangular or square structure, so that the hook 203 can easily pass through the through slot 403 and extend to the bottom of the support seat 401 , so that the workpiece can be smoothly lifted by the hook 203 .

[0035] A buffer spring 405 is provided on the top surface of the support portion 404, and a buffer block 406 is connected to the top of the buffer spring 405. When the connection seat 202 is inserted into the support groove 402, the bottom of the connection seat 202 is in direct contact with the buffer block 406. When the wire rope 302 breaks, the hook assembly 2 that is used to retrieve the workpiece will originally fall due to gravity, but because the support seat 401 can support the connection seat 202 of the hook assembly 2, the hook assembly 2 and the workpiece are prevented from falling, and the buffer spring 405 can buffer the force of the sudden fall of the hook assembly 2 and the workpiece, preventing damage to the support seat 401.

[0036] The transverse moving assembly 5 includes a transverse moving rail 501, which is arranged on the support seat 401, and the transverse moving rail 501 is arranged across both ends of the support seat 401 along the length direction. In the present utility model, the support seat 401 can move relative to the length direction of the transverse moving rail 501 to cooperate with the movement of the support seat 401 along the length direction of the gantry 1 along the hook assembly 2. As another alternative embodiment, the support seat 401 can also be fixedly connected to the transverse moving rail 501, and the support seat 401 is located in the middle of the transverse moving rail 501.

[0037] The support seat 401 is provided with a slide rail slot 407, and the transverse guide rail 501 is slidably arranged in the slide rail slot 407. In order to make the sliding process of the support seat 401 and the transverse guide rail 501 smoother, the height of the slide rail slot 407 is greater than the height of the transverse guide rail 501, and a slide rail roller 408 is provided on the top of the slide rail slot 407, and the slide rail roller 408 can move on the transverse guide rail 501 along the length direction of the transverse guide rail 501. Through the cooperation of the slide rail roller 408 and the transverse guide rail 501, the support seat 401 can move more smoothly along the transverse guide rail 501.

[0038] In the present invention, there are two transverse guide rails 501 , which are arranged in parallel. The two transverse guide rails 501 are respectively arranged on both sides of the support seat 401 in the width direction so as to avoid the position arrangement of the support groove 402 and the through groove 403 .

[0039] Limiting blocks 502 are fixedly provided at both ends of the two transverse guide rails 501 . The limiting blocks 502 can cooperate with the longitudinal limiting assembly 6 to relatively limit and fix the height position of the transverse guide rails 501 through the limiting blocks 502 .

[0040] There are two longitudinal limit assemblies 6, which are respectively arranged on the frame bodies on the left and right sides of the gantry 1, and the two longitudinal limit assemblies 6 are arranged opposite to each other. The longitudinal limit assembly 6 includes a limit column 601, and a limit groove 101 matching the limit column 601 is opened on the frame bodies on the left and right sides of the gantry 1. The limit column 601 is arranged in the limit groove 101 and can slide horizontally in the limit groove 101, so that the limit column 601 can be relatively close to or away from the limit block 502.

[0041] A plurality of limit blocks 602 are arranged on one side of the limit column 601 facing the limit block 502. The limit blocks 602 are evenly distributed along the height direction of the limit column 601, and the distance between the upper and lower limit blocks 602 is not less than the height of the limit block 502, so that the limit block 502 can smoothly overlap and abut against the top surface of any limit block 602 as needed, so as to support and limit the entire transverse movement assembly 5 and the support assembly 4. When the position of the transverse movement assembly 5 and the support assembly 4 needs to be limited, the two limit columns 601 can move in the direction of their corresponding limit blocks 502, respectively, so that the limit block 502 can abut against the limit block 602 at a specific height, presenting the following Fig. 9 When the support assembly 4 and the lateral movement assembly 5 need to be adjusted in height along with the hook assembly 2, the two limit posts 601 can be moved away from the limit block 502, so that the limit block 602 can be separated from the limit block 502, thereby avoiding obstruction of the up and down adjustment of the support assembly 4 and the lateral movement assembly 5, as shown in FIG. Figure 1 and 3 The working status shown.

[0042] The position of the limit column 601 can be adjusted by the adjustment component to control the limit column 601 to be relatively close to or away from the limit block 502. In this embodiment, the adjustment component is an adjustment cylinder 604, and the adjustment cylinder 604 is fixedly arranged on the gantry 1. An adjustment rod 603 is vertically connected to the side of the limit column 601 away from the limit block 602, and the adjustment rod 603 passes through the gantry 1 and extends to the outside of the gantry 1. The piston rod of the adjustment cylinder 604 is fixedly connected to one end of the adjustment rod 603 located on the outside of the gantry 1, so that when the piston rod of the adjustment cylinder 604 is extended and retracted, it can drive the limit column 601 through the adjustment rod 603 and then drive the limit block 602 to be relatively close to or away from the limit block 502.

[0043] As another alternative implementation, manual adjustment can be adopted. The adjusting rod 603 is set as a screw rod, and the adjusting rod 603 is threadedly connected to the gantry 1, and the adjusting rod 603 is rotatably connected to the limit column 601. The displacement of the limit column 601 can be driven by rotating the adjusting rod 603.

[0044] In the utility model, the depth of the limit groove 101 can allow the limit column 601 and the limit block 602 to be completely received in the limit groove 101, so as to prevent the longitudinal limit assembly 6 from hindering the up and down adjustment of the transverse movement assembly 5 and the support assembly 4 when there is no need to limit the transverse movement assembly 5 and the support assembly 4.

[0045] Working principle: The utility model provides a device for preventing the finished box prefabricated beam from falling when the gantry crane is lifting and moving the workpiece. The hook assembly 2 is inserted into the support groove 402 on the support seat 401 in the support assembly 4 through the connecting seat 202, and the hook 203 extends to the bottom of the support seat 401 through the through groove 403 to lift the workpiece. After the hook 203 has lifted the workpiece and adjusted the appropriate height of the hook assembly 2, the piston rod of the adjustment cylinder 604 is extended to drive the limit block 602 to approach the limit block 502 of the transverse movement assembly 5, and the limit block 502 can be against the limit block 602 at a specific height, presenting the following Fig. 9 If the steel wire rope 302 suddenly breaks when the gantry crane is moving, the hook assembly 2 can be supported by the support assembly 4 and the longitudinal limit assembly 6, so that the longitudinal limit assembly 6 can play a limiting role when the gantry crane drives the workpiece to move, and the workpiece will not fall to the ground.

[0046] When the hook assembly 2 is adjusting its height, it will drive the support assembly 4 and the transverse movement assembly 5 to adjust synchronously. During the adjustment, the piston rod of the regulating cylinder 604 contracts, so that the limit block 602 of the longitudinal limit assembly 6 is completely received in the limit groove 101, and will not hinder the up and down movement adjustment of the transverse movement assembly 5.

[0047] If the hook assembly 2 or the wire rope 302 needs to be replaced, the connecting seat 202 can be directly pulled out of the supporting groove 402 to release the connection between the hook assembly 2 and the supporting assembly 4. After replacement, the connecting seat 202 can be reinserted into the supporting groove 402.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
