[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting auxiliary device for bridge engineering construction. Background Technology

[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. During bridge construction, due to the large size and weight of the steel reinforcement and connecting components, hoisting equipment is required.

[0003] As shown in the reference case "A Lifting Auxiliary Device for Bridge Engineering Construction" (Announcement No. CN221876357U), this utility model improves the stability of the device on the boom by using a second handle, a second screw, a movable block, a fixed rod, a limiting block, a movable rod, a spring, and a limiting groove. This facilitates the disassembly of the device to replace the appropriate lifting clamps and improves the ease of use of the device. The first handle, the first screw, the movable column, the limiting rod, and the clamping block improve the stability of the device in holding materials, making it easier to remove the materials after arriving at the lifting location.

[0004] The aforementioned utility model uses clamping blocks to clamp the reinforcing bars that penetrate the main body in order to achieve stability during the clamping and hoisting of the reinforcing bars. However, since the connecting parts in the bridge construction process are not limited to round reinforcing bars, the fixed clamping blocks cannot be used for other irregularly shaped connecting parts, which leads to the low applicability of the hoisting auxiliary device. Utility Model Content

[0005] Therefore, it is necessary to provide a bridge construction hoisting auxiliary device to address the problem that, since bridge construction often involves connectors that are not limited to round steel bars, the fixed clamping blocks cannot be used with other irregularly shaped connectors, resulting in low applicability of hoisting auxiliary devices.

[0009] The auxiliary support mechanism is located at both ends of the bottom of the fixed frame.

[0010] In one embodiment, a convex ball is fixedly provided at the end of the telescopic column, and a rotating groove is provided on the side wall of the telescopic column facing the abutment. The rotating groove is sleeved on the outside of the convex ball and rotatably connected to the outer arc surface of the convex ball.

[0011] In one embodiment, the end of the abutment is provided with an anti-slip pad.

[0012] In one embodiment, the side wall of the clamp is provided with a plurality of slots, and the telescopic column is inserted into the inside of the slot respectively. The side wall of the telescopic column is connected to the inner wall of the slot by a spring. Limiting grooves are provided on both sides of the inner wall of the slot. The outer arc surface of the telescopic column located inside the slot is provided with a limiting block corresponding to the limiting groove. The limiting block is slidably disposed inside the limiting groove.

[0013] In one embodiment, the end of the limiting groove does not communicate with the side wall of the clamp.

[0014] In one embodiment, the drive assembly includes a drive motor and a bidirectional screw. The bidirectional screw is rotatably disposed inside the fixed frame. The end of the bidirectional screw passes through the side wall of the fixed frame and is keyed to the output shaft of the drive motor fixedly disposed on the outer side wall of the fixed frame. The top ends of the two sets of clamps are threadedly sleeved on the opposite threads on both sides of the bidirectional screw. A guide rod is fixedly disposed inside the fixed frame below the bidirectional screw. The top end side walls of the two sets of clamps are slidably sleeved on the outside of the guide rod.

[0015] In one embodiment, the bottom surface of the fixing frame is provided with a sliding groove directly below the guide rod, and the side walls of the two sets of clamps are slidably connected to the inner wall of the sliding groove.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The following is combined with Figures 1-5 This utility model describes a bridge construction hoisting auxiliary device.

[0030] In one embodiment, a bridge construction hoisting auxiliary device includes: a fixed frame 100, with lifting rings 101 connected to hoisting equipment around its top perimeter;

[0031] The clamping mechanism 300 is located below the fixed frame 100 and is used to clamp bridge construction connectors of different shapes. The clamping mechanism 300 includes clamping seats 304 and a drive assembly. The clamping seats 304 are respectively located on both sides of the bottom surface of the fixed frame 100, and the drive assembly is located inside the fixed frame 100. The side walls of the two sets of clamping seats 304 opposite to each other are provided with adaptation components 306 that can adapt to different connectors.

[0032] The adaptation component 306 includes a telescopic column 307, which is movably disposed inside the clamp 304. The end of the telescopic column 307 is provided with a stop 308, and the end of the stop 308 abuts against the connector.

[0033] Auxiliary support mechanism 200 is provided at both ends of the bottom of the fixed frame 100;

[0034] like Figure 5 As shown, a convex ball 313 is fixedly provided at the end of the telescopic column 307, and a rotating groove 314 is provided on the side wall of the abutment 308 facing the telescopic column 307. The rotating groove 314 is sleeved on the outside of the convex ball 313 and rotatably connected to the outer arc surface of the convex ball 313. An anti-slip pad 315 is provided at the end of the abutment 308.

[0035] In this embodiment, a convex ball 313 is provided at the end of the telescopic column 307, and a rotating groove 314 is provided on the side wall of the abutment 308. The rotating groove 314 is sleeved on the outside of the convex ball 313 and rotatably connected to the outer arc surface of the convex ball 313. When the driving assembly drives the two sets of clamps 304 to clamp the connector, the abutment 308 at the end of the telescopic column 307 contacts the connector first. Since the abutment 308 is sleeved on the outside of the convex ball 313, the abutment 308 can be rotated and adjusted according to the curved surface of the connector.

[0036] Furthermore, the end of the abutment 308 should be provided with an anti-slip pad 315. The anti-slip pad 315 is provided to increase the friction between the abutment 308 and the connector, thereby further increasing the stability of the connector during clamping and hoisting.

[0037] like Figure 4As shown, the side wall of the clamp 304 is provided with a number of slots 311, and the telescopic column 307 is inserted into the inside of the slot 311 respectively. The side wall of the telescopic column 307 is connected to the inner wall of the slot 311 through the spring 309. Limiting grooves 312 are provided on the inner walls of both sides of the slot 311. The outer arc surface of the telescopic column 307 located inside the slot 311 is provided with a limiting block 310 corresponding to the limiting groove 312. The limiting block 310 is slidably disposed inside the limiting groove 312.

[0038] The end of the limiting groove 312 is not connected to the side wall of the clamp 304;

[0039] In this embodiment, several slots 311 are provided on the side wall of the clamp 304. The telescopic column 307 is inserted into the slot 311 by the spring 309. When the two sets of clamps 304 are driven by the drive assembly to clamp and lift the connector, the telescopic column 307 slides into the slot 311 under the pressure of the connector, so as to ensure that the abutment 308 can adapt to connectors of different shapes, further realizing the clamping and lifting of connectors of different shapes, and increasing the applicability of this utility model.

[0040] like Figure 3 As shown, the drive assembly includes a drive motor 301 and a bidirectional screw 302. The bidirectional screw 302 is rotatably disposed inside the fixed frame 100. The end of the bidirectional screw 302 passes through the side wall of the fixed frame 100 and is keyed to the output shaft of the drive motor 301, which is fixedly disposed on the outer side wall of the fixed frame 100. The top ends of two sets of clamps 304 are threadedly sleeved on the opposite threads on both sides of the bidirectional screw 302. A guide rod 303 is fixedly disposed inside the fixed frame 100 below the bidirectional screw 302. The top side walls of the two sets of clamps 304 are slidably sleeved on the outside of the guide rod 303.

[0041] The bottom surface of the fixing frame 100 is provided with a sliding groove 305 directly below the guide rod 303, and the side walls of the two sets of clamps 304 are slidably connected to the inner wall of the sliding groove 305.

[0042] In this embodiment, a bidirectional screw 302 is provided inside the fixing frame 100. The end of the bidirectional screw 302 passes through the side wall of the fixing frame 100 and is keyed to the output shaft of the drive motor 301 provided on the outer side wall of the fixing frame 100. Two sets of clamps 304 are threaded onto the outside of the threads at the two ends of the bidirectional screw 302, which are different from the threads at the two ends of the bidirectional screw 302. When the drive motor 301 drives the bidirectional screw 302 to rotate, the two sets of clamps 304 move relative to each other to clamp the connecting piece. When the two sets of clamps 304 move in opposite directions, they lower the connecting piece.

[0043] like Figure 2As shown, the auxiliary support mechanism 200 includes a winding motor 201 and a winding reel 202. The bottom surface of the fixed frame 100 is provided with through slots 203 on both sides of the slide groove 305. The winding motor 201 is respectively arranged on both sides of the slide groove 305. The output shaft of the winding motor 201 is respectively connected to the winding reel 202. The inner wall of the winding reel 202 is connected to one end of the lifting rope 204. The other end of the lifting rope 204 passes through the through slot 203 and is connected to the bottom surface of the fixed frame 100.

[0044] In this embodiment, retractable lifting ropes 204 are respectively provided on both sides of the slide groove 305 at the bottom of the fixed frame 100. After the clamping mechanism 300 clamps and lifts the connector, the lifting ropes 204 on both sides are placed below the connector. By starting the winding motor 201, the winding reel 202 is driven to wind the lifting ropes 204. When the lifting ropes 204 are wound to be secure with the connector, the winding stops. The lifting ropes 204 on both sides support and stabilize the clamped connector, preventing it from shaking or tilting during the lifting and transportation process, which could cause the connector to fall.

[0045] Working principle: In use, the fixed frame 100 is connected to the hoisting equipment by passing the hoisting rings 101 around the top of the fixed frame 100 through the hoisting rope 204. The height of the fixed frame 100 is adjusted by the hoisting equipment. The drive motor 301 is started to drive the bidirectional screw 302 to rotate, so that the two sets of clamps 304 clamp the connector. When the two sets of clamps 304 clamp the connector, the telescopic column 307 is pressed into the slot 311 by the connector during the clamping process, thereby realizing adaptive clamping according to the connector of different shapes and increasing the applicability of this utility model.

[0046] Additional notes:

[0047] In this application, the winding motor 201 drives the winding reel 202 to wind the suspension rope 204. These devices are of a relatively mature type in the prior art and can be selected according to actual use needs, so they will not be described in detail here.

[0048] It should be noted that the winding motor 201 and drive motor 301 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the winding motor 201 and drive motor 301 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
