Description

Technical Field

[0001] This utility model belongs to the field of construction equipment, and specifically relates to a small hoisting device for civil construction. Background Technology

[0002] Small lifting devices used in civil construction are equipment used to assist in the hoisting of materials during civil construction. Currently, some small lifting devices used in civil construction have certain shortcomings in terms of stability. Due to the lack of a stable base structure, the device is easily affected by external forces during operation. For example, on construction sites with uneven ground or slight vibrations, the device is prone to swaying or even tilting due to the lack of effective buffering and balancing structures. This leads to instability in the hoisting process, affecting the accuracy of material hoisting and increasing the risk of collisions. This shortcoming is mainly due to insufficient consideration of complex construction environments in the design, with an overemphasis on lightness and simplification of the support structure. Conventional solutions include adding sandbags or other heavy objects around the device to increase stability, or using wedges or other fixing devices. However, these methods have obvious drawbacks. Adding sandbags or other heavy objects increases the workload and cost, and it is difficult to accurately adjust the balance; wedge fixing is cumbersome, and the fixing effect is poor in special situations such as soft ground. It is also possible that the wedges will shift due to device swaying, making it impossible to continuously guarantee the stability of the device. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figures 1 to 3As the first embodiment of this utility model: a small hoisting device for civil construction, including: a base assembly 100 and a hoisting assembly 200. The upper surface of the base assembly 100 is equipped with the hoisting assembly 200 for construction hoisting. The base assembly 100 includes a base plate 110 for moving and fixing. The upper surface of the base plate 110 is equipped with a base plate 140 through a buffer member 150. The hoisting assembly 200 includes a rotating member for rotating. The upper surface of the rotating member is equipped with a support arm 230. The end of the support arm 230 away from the rotating member is equipped with a hoisting member. The end of the hoisting member away from the support arm 230 is rotatably equipped with a hook 260 through a hoisting rope 270.

[0021] A support leg 120 is installed at each of the four corners of the lower surface of the base plate 110. Four casters 130 with self-locking structure are installed on the lower surface of the base plate 110. The support legs 120 are threadedly connected to the base plate 110. The length and width of the base plate 110 are greater than the length and width of the base plate 2 140.

[0022] A buffer 150 is installed through each of the four corners of the upper surface of the second base plate 140. The buffer 150 is a spring damper. The second base plate 140 is installed through the buffer 150 at the center axis position of the upper surface of the first base plate 110.

[0023] In use, the user first moves the device to a suitable position using the casters 130 on the underside of the base plate 110. After moving the device to the suitable position, the user can rotate the support leg 120 so that the side of the support leg 120 away from the base plate 110 contacts the ground, thus providing support for the base plate 110. After the base plate 110 is fixed, the user can then proceed with hoisting. Before hoisting, the user can remove a counterweight and place it between the base plate 110 and the base plate 140 to increase the weight of the entire base assembly 100, thereby preventing the hoisting assembly 200 from tilting during hoisting. When in use, the buffer 150 connected to the base plate 140 buffers the pressure generated during the hoisting of the lifting assembly 200, making the hoisting assembly 200 more stable during hoisting (the buffer 150 is a spring damper, and its structure is existing technology; the specific working principle will not be elaborated here). Since the base plate 110 is used to move to a suitable construction position and the device is stably positioned through the fixing measures of the support legs 120, the base plate 140 is installed on the base plate 110 through the buffer 150, which can effectively buffer the vibration and impact generated during hoisting operations, reduce device sway, improve stability, protect equipment components, extend the service life of the device, and at the same time reduce the impact on the surrounding environment and structure.

[0024] Please see Figures 1 to 3As a second embodiment of the present invention: based on the description in the above embodiments, the rotating component further includes a mounting plate 210, a column 220 and a rotating shaft 221. The mounting plate 210 is installed at the center of the upper surface of the base plate 2 140. The column 220 is welded to the upper surface of the mounting plate 210. A rotary motor 280 is provided inside the column 220. The rotating shaft 221 is rotatably mounted on the upper end of the column 220 through the rotary motor 280.

[0025] A support arm 230 is installed at the end of the rotating shaft 221 away from the column 220. The support arm 230 is inclined. The lifting components include a first lifting rod 240 and a second lifting rod 250. The upper end of the support arm 230 is hinged to the first lifting rod 240. The second lifting rod 250 is telescopically installed inside the first lifting rod 240 through a telescopic rod.

[0026] An electric push rod 290 is hinged between the lifting rod 240 and the support arm 230. A rotary motor 280 is installed on the outer surface of the lifting rod 250. A rotating shaft is installed inside the lifting rod 250 via the rotary motor 280. A lifting rope 270 is rotatably installed on the outer surface of the rotating shaft.

[0027] A hook 260 is installed at the lower end of the lifting rope 270, and the lifting rope 270 is a steel wire rope;

[0028] In use, after determining the position of the device through the operation steps of the first embodiment, the user can then activate the rotary motor 280 inside the column 220 to rotate the rotary motor 280 (the rotary motor 280 is a forward and reverse stepper motor, the structure and working principle of which are existing technologies and will not be described in detail here), thereby driving the rotating shaft 221 to rotate, which in turn drives the support arm 230 to rotate, facilitating the user to adjust the hoisting direction. Simultaneously, when adjusting the hoisting direction, the user can activate the electric push rod 290 inside the hoisting rod 240 and the electric push rod 290 hinged between the support arm 230 and the hoisting rod 240, allowing for adjustments to both the hoisting length and hoisting height. After adjustment, the user can start the rotary motor 280 on the outer surface of the lifting boom 250, causing the output shaft of the rotary motor 280 to drive the lifting rope 270 to rotate. This allows the lifting rope 270 to be wound up through the rotary motor 280. Then, the hook 260 can be connected to the object being lifted. Repeating the above steps will complete the lifting operation. During use, the rotating component can drive the outrigger 230 to rotate flexibly, adjusting the lifting position. At the same time, the outrigger 230, together with the rotating component, provides support and rotation direction for the lifting object, making it easy to determine the appropriate lifting height and position, and conveniently and quickly hooking and lifting heavy objects. Overall, this improves the flexibility, accuracy, and convenience of the lifting operation.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
