Description

Technical Field

[0001] This utility model relates to the field of steel structure transportation technology, and in particular to a steel structure component transfer device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance.

[0003] Existing steel structure buildings require a large number of steel structure components during construction. These components are intricate, fragmented, and diverse. When loading and unloading these components on the construction site, workers need to manually remove them one by one from the transfer equipment. This method is not only extremely physically demanding but also inefficient, hindering the efficient construction of steel structures. Therefore, a steel structure component transfer device is needed to solve this problem. Utility Model Content

[0004] The main purpose of this utility model is to provide a steel structure component transfer device, which solves the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A steel structure component transfer device includes a mobile trolley, with support columns bolted to the four corners of the top of the mobile trolley. A sliding groove is provided in the inner wall of the support column, and a bearing frame is slidably arranged in the sliding groove. A hoisting mechanism is fixed on the outer wall of the support column.

[0007] The load-bearing frame includes lifting rings riveted to the top four sides, and support legs are fixed at the bottom of the four corners of the load-bearing frame. The support legs slide along the inner wall of the support column. A flip-top plate is symmetrically installed at the bottom of the inner wall of the load-bearing frame through a hinge axis. The flip-top plate and the inner wall of the load-bearing frame are connected by limit pins.

[0008] The hoisting mechanism includes a hanging ring that is attached to the lifting ring. A steel wire rope is connected to the top of the hanging ring. The steel wire rope passes through the cantilever pole and the upright pole and is wound around the bottom of the winding drum. U-shaped brackets are fixed on both sides of the outer wall of the winding drum, and a rotating shaft is fixed on the bottom surface of the U-shaped brackets.

[0009] Furthermore, the support frame has four sets, three of which are equipped with the support legs.

[0010] Furthermore, three sets of first fixed supports are fixed on the outer wall of the upright, the first fixed supports are welded to the outer wall of the support column, and the cantilever rod and the upright are rotatably connected by a rotating sleeve.

[0011] Furthermore, pulley blocks are rotatably installed at both ends of the outer side of the boom, and the wire rope slides in contact with the pulley blocks. A winding motor fixed on the U-shaped bracket is also installed on one side of the outer side of the winding drum.

[0012] Furthermore, the outer wall of the rotating shaft is rotatably connected to the second fixed support, the second fixed support is welded to the outer wall of the mobile platform, and a rotating handle is inserted into the outer wall of the rotating shaft.

[0013] Furthermore, a handrail is welded to the side wall of the bottom plate of the mobile cart, and an operation panel is provided on the handrail.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] By installing a vertically sliding load-bearing frame and hoisting mechanism on a traditional transfer cart, the hoisting mechanism uses a winding motor to drive a winding drum to wind up a steel wire rope. One end of the steel wire rope is hooked to a lifting ring, allowing the load-bearing frame of a fully loaded steel structure component to be unloaded as a whole. Moreover, the hoisted load-bearing frame can be rotated and adjusted in position using components such as a rotating sleeve, a rotating shaft, and a rotating handle, facilitating unified unloading at a suitable location. During unloading, the limit pin can be removed, and the bottom plate can be flipped to open the load-bearing frame from the outside, allowing the internal materials to be poured out. This effectively saves manpower and improves work efficiency. Attached Figure Description

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides a steel structure component transfer device, including a mobile trolley 1. Support columns 4 are bolted to the four corners of the top of the mobile trolley 1. A sliding groove is formed in the inner wall of the support column 4, and a bearing frame 2 is slidably disposed within the groove. A hoisting mechanism 3 is fixed to the outer wall of the support column 4. The bearing frame 2 includes lifting rings 202 riveted to the four sides of the top. Support legs 201 are fixed to the bottom of the four corners of the bearing frame 2. The support legs 201 slide along the inner wall of the support column 4. A flip-top plate 204 is symmetrically installed via a hinge axis, and a limit pin 203 passes through the inner wall of the flip-top plate 204 and the bearing frame 2. The hoisting mechanism 3 includes a hanging ring 301 that is hooked to the lifting ring 202. A wire rope 302 is connected to the top of the hanging ring 301. The wire rope 302 passes through the cantilever rod 304 and the upright rod 306 and is wound around the bottom of the winding drum 309. U-shaped brackets 310 are fixed on both sides of the outer wall of the winding drum 309. A rotating shaft 312 is fixed on the bottom surface of the U-shaped bracket 310.

[0025] In the above embodiment, the loading and unloading of the bearing frame 2 are both placed outside the mobile trolley 1. The hoisting mechanism 3 moves the frame into and out of the inner groove of the support leg 201. After unloading, the empty frame can be manually loaded. When the limit pin 203 is inserted, the flipping base plate 204 cannot rotate, thus supporting the loading of the internal workpiece. When unloading, the bearing frame 2 touches the ground first, and then the limit pin 203 is removed to avoid the workpiece squeezing the base plate due to its large weight, making it difficult to pull out.

[0026] The rotating shaft 312 at the bottom of the U-shaped bracket 310 can support the free rotation of the top structure. The winding drum 309 and the winding motor 311 form a winch structure. The winding motor 311 is a brake motor type, which can be locked when the machine stops.

[0027] The load-bearing frame 2 has four sets, three of which are equipped with support legs 201. The bottom load-bearing frame 2 is moved by the frame surface to the bottom plate of the moving plate 1, and the other three load-bearing frames 2 are supported by support legs 201.

[0028] Three sets of first fixed supports 307 are fixed on the outer wall of the upright 306. The first fixed supports 307 are welded to the outer wall of the support column 4. The cantilever 304 is rotatably connected to the upright 306 through a rotating sleeve 305. The first fixed supports 307 are used to fix and support the upright 306 so that it can maintain the rotation and hoisting of the top cantilever 304.

[0029] The outer ends of the boom 304 are rotatably equipped with pulley blocks 303, and the wire rope 302 slides in contact with the pulley blocks 303. The outer side of the winding drum 309 is also equipped with a winding motor 311 fixed on the U-shaped bracket 310. When the boom 304 rotates, the wire rope 302 can slide freely inside the boom 304 and the upright 306, and rotate synchronously with the bottom winding drum 309.

[0030] The outer wall of the rotating shaft 312 is rotatably connected to the second fixed support 313. The second fixed support 313 is welded to the outer wall of the mobile trolley 1. A rotating handle 308 is inserted into the outer wall of the rotating shaft 312. The rotating handle 308 can facilitate the user to adjust the position of the hoisted load-bearing frame 2.

[0031] Handrails 5 are welded to the side wall of the bottom plate of the mobile cart 1, and an operation panel is installed on the handrails 5.

[0032] The working principle of this device is as follows: both the loading and unloading points are connected to an external power source, and the device is controlled by the operation panel on the handrail 5.

[0033] Each layer of the load-bearing frame 2 is taken out and placed on the ground during loading. The steel structure components are placed inside the frame by hand. The handle drives the rotating shaft 312 and the U-shaped bracket 310 to rotate on the second fixed support 313. The position of the winding drum 309 and the cantilever 304 is adjusted. The cantilever 304 rotates at the top of the upright 306 through the rotating sleeve 305, so that the hanging ring 301 is located directly above the fully loaded load-bearing frame 2 on the ground. After the hanging ring 301 is attached to the lifting ring 202, the winding motor 311 drives the winding drum 309 to rotate, winding the steel wire rope 302 and lifting the load-bearing frame 2. The manual alignment of the load-bearing frame 2 with the sliding groove of the support column 4 is performed by the hoisting mechanism 3. The load-bearing frame 2 is then lowered into the mobile trolley 1. Subsequent load-bearing frames 2 are placed in the same way.

[0034] During unloading, the above operation is performed. The material is lifted out in the opposite direction. The position of the material is adjusted by rotating the sleeve 305, the handle 5 and the rotating shaft 312. After contacting the ground, the limit pin 203 is pulled out, and the bearing frame 2 is slowly lifted again. The bottom plate 204 is flipped over and opened from the bottom, and the material is slowly unloaded.

[0035] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
