Description

Technical Field

[0001] This utility model relates to the field of tower crane auxiliary technology, and in particular to a fixed base and tower crane auxiliary device. Background Technology

[0002] Tower hoisting auxiliary equipment is a specialized device developed to address the core challenges of low efficiency, high safety risks, and high labor costs in high-altitude operations (such as tower maintenance, equipment hoisting, and cable laying) in industries like power and communications. In the process of achieving stable operation of the tower hoisting auxiliary equipment, the fixed base of the tower hoisting auxiliary equipment is a key supporting component that ensures its installation accuracy and operational safety, directly determining the operational stability and safety of the auxiliary hoisting equipment.

[0003] However, most of the tower-mounted auxiliary lifting device fixing bases currently widely used in the industry generally suffer from two major pain points: First, they lack mobility, making it difficult to conveniently and accurately move them to the ideal installation location. Because the fixing bases themselves need to have a certain load-bearing strength, they are usually made of metal and are quite heavy. Manual handling requires significant physical effort and multiple people working together, resulting in a time-consuming and inefficient transfer process. This is especially true in complex terrain around the tower (such as mountainous or hilly areas) or in narrow working spaces, where moving and adjusting the bases is extremely difficult, greatly impacting the overall work progress. Second, they lack ease of installation, making it difficult to quickly and securely fix them to the target location, and there are also obstacles to their compatibility with the tower-mounted auxiliary lifting device. Existing fixing structures often rely on complex bolt splicing or customized connectors, requiring on-site calibration and operation by professional technicians, which is difficult for ordinary workers to complete independently. There is also a risk of loosening due to vibration or external forces after fixing. Furthermore, the interfaces between the bases and the auxiliary lifting device lack universality, requiring repeated adjustments during installation, further increasing the operational difficulty and extending equipment deployment time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a fixed base and a tower-mounted auxiliary hoisting device.

[0005] The technical solution adopted in this utility model is as follows: Firstly, a fixed base is provided, comprising: The base body is equipped with an installation module; the installation module is configured to install a tower crane auxiliary device. A movable fixing mechanism is symmetrically arranged on both sides of the base body along the central axis of the base body; the movable fixing mechanism includes a support frame installed on the base body, a rolling element rotatably installed on the support frame, and a drive unit installed on the base body and connected to the support frame; wherein, the drive unit drives the support frame to rise or fall.

[0006] In one embodiment of the present invention, the movable fixing mechanism further includes a guide module disposed on the base body; the guide module is configured to guide the support frame to move along a fixed straight line.

[0007] In one embodiment of the present invention, the guide module includes a guide rod fixed to the base body, a slider slidably connected to the guide rod and fixedly connected to the support frame, and a baffle installed on the end of the guide rod away from the slider.

[0008] In one embodiment of the present invention, the drive unit includes a fixed frame mounted on the base body and an electric push rod mounted on the fixed frame; the actuating end of the electric push rod is connected to the support frame.

[0009] In one embodiment of the present invention, the support frame includes a first flange plate, a web plate, and a second flange plate; the first flange plate and the second flange plate are arranged in parallel, and the first flange plate and the second flange plate are provided on both sides of the web plate; the rolling element is rotatably installed between the first flange plate and the second flange plate.

[0010] In one embodiment of the present invention, the first flange, the web and the second flange are integrally formed.

[0011] In one embodiment of the present invention, the base body has at least one first through hole; a fastening element is installed in the first through hole.

[0012] In one embodiment of this utility model, the support frame and the base body have the same length.

[0013] In one embodiment of the present invention, the mounting module includes a positioning groove formed on the top of the base body and a second through hole formed circumferentially in the base body along the positioning groove.

[0014] Secondly, a tower-mounted auxiliary hoisting device is provided, including a fixed base as described above.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: The fixed base described in this utility model, through the setting of a movable fixing mechanism, can achieve the functions of moving the fixed base to a suitable position and fixing the fixed base to a specific installation position. During use, the fixed base is moved to a suitable position by the rolling element rolling on the ground. The driving unit is activated to disengage the rolling element from the ground, and then the fixed base is installed in the specific installation position through the cooperation of the first through hole and the fastening element. This avoids the situation where it is difficult to move the base to a suitable position, resulting in a large weight of the base and the tower hoisting device, and requiring a long time and a lot of effort to move the fixed base manually. This ensures the flexibility of the fixed base and avoids the situation where it is difficult to fix the base to a suitable position, requiring professional personnel to fix the fixed base to the specific installation position, thus ensuring the ease of installation of the fixed base.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0024] In existing technologies, high-altitude operations in the power and telecommunications industries often face challenges such as difficulties in moving fixed bases and complex installations. Traditional bases are inefficient to move due to their heavy weight, and adjusting their position in complex terrain is time-consuming and labor-intensive. Fixed structures rely on bolted connections and custom-made connectors, requiring professional personnel for installation and posing a risk of loosening. During a tower maintenance operation, workers needed to move the auxiliary lifting device base to a designated location in a narrow mountainous environment, but the lack of an effective moving mechanism led to multiple adjustment failures, ultimately delaying the project.

[0025] To address these issues, researchers discovered that the poor mobility stemmed from the base's lack of autonomous movement, requiring manual handling; and the low installation efficiency arose from the complex fixed structure and lack of universal interfaces. By analyzing mechanical transmission principles, they proposed installing lifting and moving mechanisms on both sides of the base, using a drive unit to control the height of the support frame, allowing the rolling elements to contact the ground for movement. Simultaneously, they designed standardized installation modules to simplify the docking process for auxiliary lifting devices.

[0026] Therefore, combining Figure 1 and Figure 2 This embodiment proposes a fixed base, including a base body 10 and movable fixing mechanisms 20 symmetrically arranged on both sides of the base body 10 along its central axis. The base body 10 is provided with an installation module 30. The installation module 30 is configured to install a tower crane auxiliary device. The movable fixing mechanism 20 includes a support frame 204 mounted on the base body 10, a rolling element 206 rotatably mounted on the support frame 204, and a drive unit mounted on the base body 10 and connected to the support frame 204. The drive unit drives the support frame 204 to rise or fall.

[0027] This embodiment further proposes that the movable fixing mechanism 20 also includes a guide module disposed on the base body 10. The guide module is configured to guide the support frame 204 to move along a fixed straight line. Specifically, the guide module includes a guide rod 201 fixed to the base body 10, a slider 202 slidably connected to the guide rod 201 and fixedly connected to the support frame 204, and a baffle 203 installed on the end of the guide rod 201 away from the slider 202.

[0028] The guide rod 201 is a rigid rod-like structure extending vertically, which provides a linear motion track for the slider 202, ensuring that the support frame 204 moves only along a single axis. The slider 202 is a sliding component that matches the cross-sectional shape of the guide rod 201, specifically a metal block with ball bearings. Its function is to convert the vertical movement of the support frame 204 into linear movement along the guide rod 201, eliminating the risk of lateral deviation. The baffle 203 is a limiting structure located at the end of the guide rod 201, specifically a metal plate or reinforcing rib. The baffle 203 is fixed to the end of the guide rod 201 by bolts or welding to prevent the slider 202 from detaching from the guide rod 201.

[0029] Specifically, the guide rod 201 is arranged along the longitudinal axis of the base body 10, and the slider 202 forms a sliding pair with the guide rod 201 through an internal through hole. The support frame 204 is fixedly connected to the slider 202 by bolts or welding. When the drive unit drives the support frame 204 to move, the slider 202 slides along the guide rod 201, and the baffle 203 limits the stroke range of the slider 202, thereby ensuring that the support frame 204 always moves up and down along a straight path and avoids jamming or positional deviation caused by skewness.

[0030] Combination Figure 3 The drive unit includes a fixed frame 207 mounted on the base body 10 and an electric push rod 208 mounted on the fixed frame 207. The actuating end of the electric push rod 208 is connected to a support frame 204. Specifically, the support frame 204 includes a first flange, a web, and a second flange. The first flange and the second flange are arranged in parallel, and the first flange and the second flange are provided on both sides of the web. A rolling element 206 is rotatably mounted between the first flange and the second flange.

[0031] The fixed frame 207 is a structural component fixed to the base body 10, providing a stable mounting foundation for the electric actuator 208. It can be fixed to the base body 10 by welding or bolting. The electric actuator 208 is a linear actuator driven by electricity, used to convert rotary motion into linear motion. It can be implemented using an electric actuator with a motor and lead screw structure. The extension and retraction of the actuator are driven by controlling the forward and reverse rotation of the motor, thereby causing the support frame 204 to move up and down.

[0032] The first and second flanges are connected by a web to form an I-shaped cross-section structure. A rolling element 206 is mounted between the two flanges via a pivot 205. When the drive unit moves the support frame 204 up and down, the web bears the vertical load and distributes it to the two flanges. The rolling element 206 rolls along the contact surface during movement, avoiding positioning deviations caused by sliding friction. The parallel arrangement of the two flanges keeps the mounting axis of the rolling element 206 horizontal, ensuring the straightness of the movement trajectory.

[0033] Specifically, when the position of the support frame 204 needs to be adjusted, the electric push rod 208 generates linear motion through the drive of the motor, pushing or pulling the support frame 204 to move vertically. The lifting and lowering of the support frame 204 causes the rolling element 206 to contact or disengage from the ground. When moving, the rolling element 206 contacts the ground to facilitate the movement of the base body 10; when fixed, the rolling element 206 is lifted off the ground so that the base body 10 directly contacts the ground to enhance stability. The presence of the fixing frame 207 ensures that the electric push rod 208 maintains stable support during operation, avoiding displacement or vibration caused by uneven force.

[0034] Furthermore, the first flange, web, and second flange are integrally formed. Integral forming refers to the process of combining multiple independent components into a single structure through a comprehensive machining process. This can be achieved using casting or welding processes, eliminating assembly gaps between components and enhancing the overall structural integrity.

[0035] Furthermore, the support frame 204 and the base body 10 have the same length. The fact that the length of the support frame 204 is the same as that of the base body 10 ensures that the movable fixing mechanism 20 forms a symmetrical and continuous support surface on both sides of the base body 10, avoiding local stress concentration or installation misalignment caused by length differences.

[0036] The base body 10 has at least one first through hole 209. A fastening element 210 is installed in the first through hole 209. The first through hole 209 is a hole structure that penetrates the thickness of the base body 10, used to accommodate the fastening element 210 passing through the base body 10 and connecting it to the external support surface. The fastening element 210 is a connecting component used to fix the base body 10 to the target position, which can be implemented by bolts, achieving a rigid connection between the base body 10 and the support surface through mechanical locking.

[0037] Specifically, the base body 10 forms a standardized installation interface through a first through hole 209. The fastening element 210 passes through the first through hole 209 and can be directly fixed to the external support surface. When the position of the base body 10 needs to be adjusted, simply loosen the fastening element 210, move the base body 10 to the new position, and then re-tighten the fastening element 210. This design avoids the drawbacks of traditional bases that rely on complex splicing structures, simplifying the installation process.

[0038] like Figure 4As shown, the mounting module 30 includes a positioning groove 301 formed on the top of the base body 10 and a second through hole 302 formed circumferentially along the positioning groove 301 in the base body 10. The positioning groove 301 is a recessed structure on the top of the base body 10, used to define the installation position of the tower-mounting auxiliary lifting device. The second through hole 302 is a through hole distributed around the edge of the positioning groove 301, which can be a threaded hole or a smooth hole, used to install bolts or pins to fix the tower-mounting auxiliary lifting device. The number of second through holes 302 can be four or six, depending on the weight and stress requirements of the auxiliary lifting device.

[0039] In some specific embodiments, the depth of the positioning groove 301 can be one-third to one-half of the thickness of the base body 10, the diameter of the second through hole 302 can be 12 mm or 16 mm, and the thread specification can be M12 or M16. The inner wall of the positioning groove 301 can be provided with anti-slip texture, and an elastic washer can be pre-installed in the second through hole 302 to enhance connection stability.

[0040] This embodiment also provides a tower-mounted auxiliary hoisting device, including the aforementioned fixed base.

[0041] The working principle of this embodiment is as follows: When the base body 10 needs to be moved, the drive unit pushes the support frame 204 down, causing the rolling element 206 to contact the ground and lifting the base body 10 off the ground. After the operator can easily push the base body 10 to the target position, the drive unit retracts, causing the support frame 204 to rise, and the base body 10 directly contacts the ground for fixation. The positioning slot 301 of the mounting module 30 matches the bottom flange of the tower crane auxiliary device. After the operator places the tower crane auxiliary device into the positioning slot 301, it is tightened using bolts passing through the second through hole 302. This design allows the base body 10 to reduce movement resistance during the moving phase through rolling friction, and maintain stability during the fixing phase through the weight of the base body 10 and the friction with the ground.

[0042] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
