Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an electric single-beam crane with a safety protection structure. Background Art

[0002] Single-beam bridge crane is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of the single-beam bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest type of lifting machinery.

[0003] According to the patent website published "An electric single-beam crane with a safety protection structure (Announcement No.: CN219950267 U; application number: 202321191411.4)" The above application is aimed at: "When the existing electric single-beam crane is used to lift the goods, the lifting rope is usually lowered to a certain length first, and then the body is moved so that the position of the body corresponds to the position of the object to be moved, and then the hook is used to lift the object. When the body moves above the object, the hook and the lifting rope will move with the body, but when the body stops, due to the inertia of the movement, the rope and the hook will continue to move under the condition of inertia, so that the rope drives the hook to swing above the object. When hanging the object, it is usually necessary to manually hang the hook on the object. The worker may stand next to the object, and the swinging hook may collide with the body of the worker, which may cause harm to the worker. "The problem is optimized, but the stable structure in the above application is only realized by limiting the hook by the 'first rotating belt 5', which is easy to pull the lifting rope to tilt when the hook moves too fast to the left and right, resulting in a jam between the 'first rotating belt 5' and the hook, which is not convenient to use.

[0026] The utility model provides a technical solution:

[0027] Embodiment 1

[0028] Combination Figures 1 to 3 An electric single-beam crane with a safety protection structure includes a supporting beam 3, a cross beam 4 is fixedly connected to the top of the supporting beam 3, a moving device 5 is arranged at the bottom of the cross beam 4, a lifting rope 51 is arranged at the bottom of the moving device 5, a stabilizing mechanism 1 is sleeved on the inner circle of the lifting rope 51, a hook 6 is arranged at the bottom of the stabilizing mechanism 1, and stabilizing mechanisms 2 2 are arranged on the left and right sides of the lifting rope 51.

[0029] The stabilizing mechanism 1 includes a transfer component 11, a connecting component 12 and a lifting component 13. The transfer component 11 is arranged on the inner circle of the lifting rope 51, the connecting component 12 is arranged on the inner circle of the transfer component 11, and the lifting component 13 is arranged on the bottom of the transfer component 11.

[0030] The transfer assembly 11 includes a rotating drum 1101, which is slidably connected to the bottom of the inner ring of the lifting rope 51, and the left and right sides of the rotating drum 1101 are fixedly connected to connecting arms 1102, and the bottom of the connecting arm 1102 is fixedly connected to a sleeve 1103, which is sleeved on the bottom of the outer ring of the rotating drum 1101, and the sleeve 1103 is slidably connected to the bottom of the outer ring of the lifting rope 51. The connecting assembly 12 includes a fixed shaft 1201, which is rotatably connected to the inner ring of the rotating drum 1101, and the front and rear sides of the fixed shaft 1201 are fixedly connected to connecting plates 1 202, the bottom of the inner side of the connecting plate 1202 is fixedly connected with the fixed shaft 2 1203, the lifting assembly 13 includes a protruding rod 1301, the protruding rod 1301 is arranged below the sleeve 1103, the protruding rod 1301 is fixedly connected with the sleeve 1302, the sleeve 1302 is rotatably connected to the outer ring of the fixed shaft 2 1203, the bottom of the protruding rod 1301 is fixedly connected with a cam 1303, the cam 1303 is fixedly connected to the top of the hook 6, the top of the cam 1303 is fixedly connected with a reinforcing fin 1304, and the reinforcing fin 1304 is fixedly connected to the bottom of the outer ring of the protruding rod 1301.

[0031] Furthermore: the connecting plate 1202 keeps the bottom end of the lifting rope 51 connected to the hook 6 via the fixed axis 1201 and the fixed axis 2 1203, so that when the lifting rope 51 shakes, the hook 6 moves and then drives the connecting plate 1202 to remain vertical under the action of gravity, thereby increasing the stability of the hook 6 during the lifting process, reducing the impact of the shaking of the bottom end of the lifting rope 51 on the hook 6, and increasing the safety of the lifting device during use.

[0032] Embodiment 2

[0033] See also Figure 1 , Figure 4 and Figure 5 On the basis of the first embodiment, it is further obtained that the stabilizing mechanism 2 includes a lifting component 21 and a limiting component 22 , the lifting component 21 is arranged at the bottom of the mobile device 5 , and the limiting component 22 is arranged inside the lifting component 21 .

[0034] The lifting component 21 includes an electric telescopic rod 2101, which is fixedly connected to the bottom of the mobile device 5 and is located on the left and right sides of the lifting rope 51. The bottom of the electric telescopic rod 2101 is fixedly connected to a transmission plate 2102, and the inner side of the transmission plate 2102 is fixedly connected to a moving seat 2103. The limiting component 22 includes a protrusion 2201, which is fixedly connected to the inner side of the moving seat 2103, and the inner side of the protrusion 2201 is fixedly connected to a fixed shaft three 2202. The outer circle of the fixed shaft three 2202 is rotatably connected to a rotating drum two 2203, and the rotating drum two 2203 is slidably connected to the inner side of the lifting rope 51.

[0035] Furthermore: the rotating drum 2203 on the left and right sides is slidably connected to the inner side of the lifting rope 51 at the left and right ends, so that the upper part of the lifting rope 51 will not shake or get tangled during the lifting process, thereby increasing the stability of the lifting rope 51 during the extension and retraction process. At the same time, the setting of the electric telescopic rod 2101 allows the rotating drum 2203 to be extended as the lifting rope 51 is extended, thereby improving the stabilizing effect of the lifting rope 51 and increasing the safety of the lifting device during use.

[0036] In actual operation, when the device is used, during the use of the lifting device, if the bottom end of the lifting rope 51 shakes, the drum 1101 and the casing 1103 will swing with the shaking of the bottom end of the lifting rope 51. During the swinging of the casing 1103 and the drum 1101, the fixed shaft 1201 transmits the swinging force of the lifting rope 51 to the sleeve 1302 through the fixed shaft 2 1203 via the connecting plate 1202, while the sleeve 1302 and the protruding rod 1301 are not fixed to the casing 1103, so that the protruding rod 1301 and the sleeve 1302 cannot follow the swinging of the casing 1103 in real time. After the swinging force of the casing 1103 is transmitted to the protruding rod 1301 to drive the protruding rod 1301 to swing, the casing 1103 has begun to swing in the opposite direction, so that the opposite swinging forces on the upper and lower sides cancel each other out, thereby reducing the swing amplitude and duration of the hook 6 when it shakes.

[0037] At the same time, when the device is in use, the electric telescopic rod 2101 also extends downward to drive the rotating drum 2203 downward during the downward extension of the lifting rope 51, reducing the length of the force arm that can participate in the action during the swing of the lifting rope 51, and physically reducing the force of the swing of the hook 6, further increasing the stability of the hook 6.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
