[0002] In the field of steel structure engineering construction, the transportation of various large components such as steel beams and steel columns is an important part of the project construction. These components are generally characterized by large size and heavy weight. In projects such as factory construction and bridge construction, the on-site transportation and installation positioning of components require specialized transportation equipment.

This technology has the following advantages: it can be freely adjusted according to the specifications of the barbell plates, and the tightening process is more efficient. It has an independent lifting support structure during the tightening process, and it is safer to use. It solves the problems of current transport trolley devices, such as the inability to achieve automatic tightening, low transport efficiency, inability to achieve automatic loading and stabilizing support, unstable center of gravity, inability to achieve isolated floating support, large wear and tear on the barbell plates during transport, and high risk of crushing accidents.

[0004] In steel structure transportation operations, due to the large size and heavy weight of steel components, the existing trolley fixing mechanism often requires separate operation at the front and rear ends of the workpiece, which not only increases the complexity of operation, but also makes it difficult to ensure the uniformity of the fixing force at both ends. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel structure transport trolley that facilitates quick and easy binding, ensuring uniform stress distribution on the workpiece and avoiding localized stress concentration. Furthermore, it enables the synchronous and rapid fixing of multiple workpieces at their front and rear ends, requiring only a single-point adjustment to complete multi-point fixing, significantly improving work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure transport trolley for easy and quick binding, comprising a handcart, wherein the handcart is equipped with a transport mechanism for carrying workpieces, and the transport mechanism includes:

[0007] The load-bearing assembly includes several load-bearing frames that are fixed longitudinally on the handcart. The bottom of each load-bearing frame is fixed to a base frame on both the left and right sides. The inner walls of each load-bearing frame are fixed to side frames on both the left and right sides. The outer walls of each load-bearing frame on both the left and right sides are fixed to axle frames at the front and rear ends. A shaft is rotatably installed between the left and right axle frames. A pressure plate is fixed to the outer wall of the shaft. A left support rod is fixed to the left end of the shaft. Several left support rods are pivotally connected to each other through the same right support rod.

[0008] An adjustment assembly is mounted on the trolley and is used to adjust the displacement of the right support rod.

[0009] Preferably, the adjustment assembly includes an outer cylinder pivotally connected to the outer wall of the left end of the trolley, a threaded rod is provided inside the outer cylinder, and a threaded knob is rotatably installed on the upper outer wall of the outer cylinder, with the inner wall of the threaded knob threadedly connected to the outer wall of the threaded rod.

[0010] Preferably, the adjusting assembly further includes a protruding rod fixed inside the outer cylinder, the outer wall of the threaded rod having a groove along the axial direction, and the inner end of the protruding rod being embedded in the groove.

[0011] Preferably, the load-bearing assembly further includes a right support rod fixed to the right end of the shaft, and the front and rear right support rods are pivotally connected by a transverse connecting rod.

[0012] Preferably, the load-bearing component further includes a plurality of first rollers rotatably mounted inside the base frame and equidistantly distributed, and a plurality of second rollers rotatably mounted inside the side frame and equidistantly distributed.

[0013] Preferably, the bearing assembly further includes a rear baffle that is fixed and slides inside the bearing frame, for limiting the rear end of the workpiece placed in the bearing frame.

[0014] Beneficial effects

[0015] This invention provides a steel structure transport trolley that is easy to quickly assemble. Compared with the prior art, it has the following advantages:

[0016] 1. After the workpiece is placed inside the support frame, the threaded rod is driven to move axially along the outer cylinder by rotating the threaded knob. The threaded rod drives the left support rod to rotate through the longitudinal connecting rod. The left support rod drives the pressure plate to flip downward through the rear shaft, thereby fixing the rear end of the workpiece below. At the same time, when the rear shaft rotates, it drives the right support rod to rotate through the right support rod and the transverse connecting rod. The front right support rod drives the pressure plate on the front shaft to flip downward synchronously, thereby fixing the front end of the workpiece below. This ensures that the workpiece is subjected to uniform force and avoids local stress concentration. Furthermore, it achieves synchronous and rapid fixing of the front and rear ends of multiple workpieces. The overall operation only requires single-point adjustment to complete multi-point fixing, which significantly improves work efficiency.

[0017] 2. The first roller supports the bottom of the workpiece to achieve smooth sliding, while the second roller guides the side of the workpiece to maintain stable movement, reducing frictional resistance during workpiece loading and unloading, facilitating workpiece placement and positioning, and effectively preventing deviation during transportation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a steel structure transport trolley for easy and quick binding, including a handcart 1, on which a transport mechanism 2 is provided for carrying workpieces, the transport mechanism 2 including:

[0026] The load-bearing assembly 21 includes several load-bearing frames 211 that are fixed longitudinally on the handcart 1. The lower left and right sides of the load-bearing frame 211 are fixed with a base frame 212. The left and right sides of the inner wall of the load-bearing frame 211 are fixed with a side frame 213. The front and rear ends of the outer walls of the left and right sides of the load-bearing frame 211 are fixed with axle frames 214. A shaft 215 is rotatably installed between the left and right axle frames 214. A pressure plate 216 is fixed to the outer wall of the shaft 215. A left support rod 217 is fixed to the left end of the shaft 215. Several left support rods 217 are pivotally connected to each other through the same right support rod 218.

[0027] Adjustment component 22 is mounted on trolley 1 and is used to adjust the displacement of right support rod 218.

[0028] In this embodiment, after the workpiece is placed inside the support frame 211, the adjustment component 22 drives the left support rod 217 to rotate through the longitudinal connecting rod 23. The left support rod 217 drives the pressure plate 216 to flip downward through the rear shaft 215, thereby fixing the rear end of the workpiece below. This makes the workpiece fixing operation simple and quick, greatly improving loading and unloading efficiency, while ensuring the stability of the workpiece during transportation. It is especially suitable for the transportation of heavy materials such as steel structural components.

[0029] Specifically, the adjustment component 22 includes an outer cylinder 221 pivotally connected to the outer wall of the left end of the handcart 1. A threaded rod 222 is provided inside the outer cylinder 221. A threaded knob 223 is rotatably installed on the upper outer wall of the outer cylinder 221, and the inner wall of the threaded knob 223 is threadedly installed with the outer wall of the threaded rod 222.

[0030] In this embodiment, when the threaded knob 223 is rotated, the threaded rod 222 is driven to move axially along the outer cylinder 221 through the threaded transmission.

[0031] Specifically, the adjusting assembly 22 also includes a protruding rod 224 fixed inside the outer cylinder 221. The outer wall of the threaded rod 222 has a groove 225 along the axial direction, and the inner end of the protruding rod 224 is embedded in the groove 225.

[0032] In this embodiment, the cooperation structure between the protruding rod 224 and the guide groove 225 not only ensures the axial linear motion accuracy of the threaded rod 222 during rotational adjustment, but also effectively prevents the threaded rod 222 from circumferentially spinning.

[0033] Specifically, the load-bearing assembly 21 also includes a right support rod 218 fixed to the right end of the shaft 215, and the right support rods 218 at the front and rear ends are pivotally connected by a transverse connecting rod 219.

[0034] In this embodiment, when the rear shaft 215 rotates, the right support rod 218 and the transverse connecting rod 219 drive the front right support rod 218 to rotate. The front right support rod 218 drives the pressure plate 216 on the front shaft 215 to flip downwards in sync, thereby fixing the front end of the workpiece below.

[0035] Specifically, the load-bearing component 21 also includes a number of first rollers 2110 rotatably mounted inside the base frame 212 and equidistantly distributed, and a number of second rollers 2111 rotatably mounted inside the side frame 213.

[0036] In this embodiment, the first roller 2110 supports the bottom of the workpiece to achieve smooth sliding, and the second roller 2111 guides the side of the workpiece to maintain stable movement, reducing the frictional resistance during workpiece loading and unloading, facilitating the workpiece to be pushed into position, and effectively preventing deviation during transportation.

[0037] Specifically, the support assembly 21 also includes a rear baffle 2112 that is fixed inside the support frame 211 and slides therein, for limiting the rear end of the workpiece placed in the support frame 211.

[0038] In this embodiment, the rear end of the workpiece in the support frame 211 is restricted by the rear baffle 2112 to prevent the workpiece from moving backward during transportation.

[0039] The working principle and usage process of this utility model are as follows: First, when the workpiece is placed inside the support frame 211, the threaded rod 222 is driven to move axially along the outer cylinder 221 by rotating the threaded knob 223. The threaded rod 222 drives the left support rod 217 to rotate through the longitudinal connecting rod 23. The left support rod 217 drives the pressure plate 216 to flip downward through the rear shaft 215, thereby fixing the rear end of the workpiece below.

[0040] Meanwhile, when the rear shaft 215 rotates, the right support rod 218, in conjunction with the transverse connecting rod 219, drives the front right support rod 218 to rotate. The front right support rod 218 drives the pressure plate 216 on the front shaft 215 to rotate downwards in sync, thereby fixing the front end of the workpiece below. This ensures that the workpiece is subjected to uniform force and avoids local stress concentration. Furthermore, it enables the synchronous and rapid fixing of the front and rear ends of multiple workpieces. The overall operation only requires single-point adjustment to complete multi-point fixing, which significantly improves work efficiency.
