Description

Technical Field

[0001] This utility model relates to the field of mechanical fixing device technology, specifically a device for fixing equipment that can be tilted. Background Technology

[0002] Existing fixed devices for installing equipment at high locations mostly use integrated long poles or wire rope-type collapsing mechanisms.

[0003] The production of one-piece long poles presents several challenges: their structure is non-adjustable and cannot be tilted, resulting in high transportation costs. Installing, erecting, or maintaining equipment on these poles requires the use of ladders or aerial work platforms, posing safety hazards. Furthermore, aerial work platforms require a certain amount of space to operate.

[0004] Wire rope-type lowering mechanisms have inherent drawbacks such as poor reliability and durability, poor holding ability, complex structure, and high cost. After prolonged exposure to light, wire ropes are prone to fatigue tension and even single-strand breakage, posing a risk of sudden failure. If the wire rope breaks, the equipment may fall rapidly, causing damage and safety hazards. Wire ropes themselves have elastic deformation; after long-term use or under load (especially heavy equipment), they will elongate to a certain extent, increasing the sway of the fixing device and equipment, making it impossible to maintain position. Wire rope-type lowering mechanisms often require additional mechanical locking devices for auxiliary fixation, typically including a winch, wire rope, multiple guide pulleys, tension adjustment mechanism, etc., resulting in numerous components, complex assembly, and high overall cost.

[0005] Therefore, there is an urgent need for a device that is simple in structure, safe and convenient to use, low in cost, and can reliably switch between the working state and the collapsed state. Utility Model Content

[0016] Furthermore, in this utility model, the trapezoidal thread and the trapezoidal nut in the upper joint constitute a threaded transmission device, which is used to drive the upper column and the equipment installed on it to rotate around the rotating shaft.

[0017] Beneficial effects: The technical solution of this application has the following technical effects: 1.

[0033] This embodiment provides a tiltable equipment fixing device, designed to solve problems such as inconvenient equipment installation and maintenance, and safety risks associated with working at heights in existing technologies. Through a unique segmented design and variable-pitch mechanism, this device achieves adjustable height and reliable self-locking of the upper column, allowing operators to complete equipment installation and maintenance from the ground. This significantly improves operational convenience and safety while reducing production difficulty and transportation costs.

[0034] The tiltable equipment fixing device in this embodiment mainly includes the following core components: lower column 1, upper column 2, column connecting plate 3, rotating shaft 4, pitch changing mechanism 5, non-detachable knob 6, movable nut 7, and crank handle 8. These components work together to realize the tilting and standing functions of the equipment fixing device, and ensure stability and reliability under different working conditions.

[0035] The lower column 1 serves as the base of the entire equipment fixing device, its primary purpose being to provide stable support. The bottom of this column is specially designed with a mechanical interface, allowing for convenient and secure connection to a fixed foundation on the ground. Through this connection, the lower column 1 effectively transfers the weight and external forces of the entire fixing device and the equipment mounted on it to the ground, ensuring the stability and safety of the equipment under various operating conditions. This reliable connection to the fixed foundation provides a solid working platform for the equipment, avoiding the risk of swaying or overturning due to an unstable foundation.

[0036] The upper column 2 is the main body of the equipment fixing device used for installing the equipment. Its main purpose is to support the equipment to be installed and to enable height adjustment and tilting functions. The top of this column is designed with mounting interfaces, which can be adapted to the installation needs of different equipment, such as surveillance cameras, communication antennas, or other outdoor equipment. Its advantage lies in providing different mounting interfaces, allowing different types of equipment to be easily and flexibly installed on the fixing device, improving the device's versatility and applicability. The upper column 2 is located above the lower column 1 and is connected to the lower column 1 via a column connecting plate 3 and a rotating shaft 4, forming a structure that can rotate relative to it.

[0037] The column connecting plate 3 is a key structural component connecting the lower column 1 and the upper column 2, its main purpose being to provide a fulcrum for the upper column 2 to rotate. The rotating shaft 4 is mounted on the column connecting plate 3, serving as the rotation center for the upper column 2's tilting movement. The column connecting plate 3 is securely connected to the lower column 1 and the upper column 2 using standard parts such as screws and nuts. The upper column 2 is hinged to the column connecting plate 3 via the rotating shaft 4. The advantage of this connection method is that it allows the upper column 2 to rotate smoothly around the rotating shaft 4 within a certain pitch angle range, thus enabling the equipment to tilt and stand up. Simultaneously, this mechanical connection structure is simple, reliable, and easy to manufacture and maintain. The column connecting plate 3 is located at the connection point between the lower column 1 and the upper column 2, and the rotating shaft 4 passes through corresponding holes in the column connecting plate 3 and the upper column 2, ensuring the rotational freedom of the upper column 2.

[0038] The pitch-changing mechanism 5 is the core component of this invention. Its main purpose is to change the relative position of the trapezoidal nut on the trapezoidal screw through the rotational movement of the trapezoidal screw in the threaded transmission mechanism, driving the upper column 2 to rotate around the shaft 4, thereby realizing the tilting and standing of the upper column 2, and reliably self-locking at any position. The advantage of this mechanism is that it provides a precise and controllable way to adjust the pitch angle of the upper column 2, allowing the height and posture of the equipment to be flexibly adjusted according to actual needs, greatly improving the adaptability and functionality of the device. At the same time, its self-locking capability ensures that the equipment can remain stable after adjustment, without the need for additional locking devices, simplifying the structure and improving reliability.

[0039] The pitch-changing mechanism 5 includes an upper left bracket 51, an upper right bracket 52, a lower left bracket 53, a lower right bracket 54, a trapezoidal lead screw 55, an upper joint 56, a lower joint 57, a waist hole support 58, a lead screw sleeve 59, a cap nut 510, and a limit nut 511.

[0040] In terms of position, the pitch-changing mechanism 5 is located between the lower column 1 and the upper column 2. Specifically, the upper left bracket 51 and the upper right bracket 52 are connected to the upper column 2 through mounting holes, forming the upper support points; the lower left bracket 53 and the lower right bracket 54 are connected to the lower column 1 through mounting holes, forming the lower support points. This connection method allows the pitch-changing mechanism 5 to convert the rotational motion input through the crank handle 8 into linear motion of the trapezoidal nut 562 along the axial direction of the trapezoidal lead screw 55, thereby driving the upper column 2 to rotate around the pivot 4.

[0041] In terms of connection, the trapezoidal lead screw 55 is the transmission core of the pitch-changing mechanism 5, and it is connected to the support via the upper joint 56 and the lower joint 57. The upper joint 56 is mounted on the trapezoidal lead screw 55 and supported by the upper left support 51 and the upper right support 52, allowing the upper joint 56 to rotate around the axis of the support hole in the support. Similarly, the lower joint 57 is also mounted on the trapezoidal lead screw 55 and supported by the lower left support 53 and the lower right support 54, also allowing the lower joint 57 to rotate around the axis of the support hole in the support. The lead screw sleeve 59 and the cap nut 510 are mainly used to protect the trapezoidal lead screw 55 from external environmental influences and to store grease to ensure the smooth operation of the trapezoidal lead screw 55 and extend its service life. The limit nut 511 is installed at a specific position on the trapezoidal lead screw 55 to prevent the relative movement between the trapezoidal lead screw 55 and the trapezoidal nut 562 from exceeding the safe stroke, thereby avoiding the risk of equipment falling. The ingenious design of the entire pitch-changing mechanism 5 ensures the stability, controllability, and safety of the upper column 2 during the falling process, as well as its reliable self-locking capability at any angle, which is the key to realizing the core function of this utility model.

[0042] The trapezoidal lead screw 55 is the core transmission component in the pitch-changing mechanism 5. Its main purpose is to convert the rotational motion of the crank handle 8 into linear motion, thereby driving the upper joint 56 to move along its axial direction, ultimately causing the upper column 2 to tilt or stand up. The trapezoidal lead screw 55 has the advantage of excellent self-locking performance. This means that after stopping the crank handle 8, the threaded pair formed by the trapezoidal lead screw 55 and the trapezoidal nut 562 can reliably maintain its current position without the need for an additional braking device, thus simplifying the structure and improving operational safety. Furthermore, the trapezoidal lead screw 55 has high transmission efficiency, enabling it to drive a large load with a small torque, reducing the physical exertion of the operator.

[0043] The trapezoidal lead screw 55 has multiple characteristic sections in its structure, including a crank interface 551, a lower thread 552, a trapezoidal thread 553, and an upper thread 554. The crank interface 551 is located at the lower end of the trapezoidal lead screw 55 and is typically designed with a square cross-section to precisely align with the square hole interface of the crank handle 8, enabling a quick-release connection. The lower thread 552 is a standard thread that passes through the movable bearing sleeve 573 and is connected via standard parts such as nuts, elastic washers, and flat washers. The trapezoidal thread 553 is the main body of the trapezoidal lead screw 55; it, together with the trapezoidal nut 562 in the upper joint 56, forms a threaded transmission device and is the core component for realizing the movement of the upper column 2. The upper thread 554 is located at the upper part of the trapezoidal lead screw 55 and is used to install a limit nut 511 to prevent the relative movement between the trapezoidal lead screw 55 and the trapezoidal nut 562 from exceeding the safe travel.

[0044] In terms of position, the trapezoidal lead screw 55 is vertically installed at the center of the pitch-changing mechanism 5, and its axis lies in the motion plane of the upper column 2. The crank handle interface 551 faces the operator for easy manual operation.

[0045] The upper joint 56 is a key component connecting the trapezoidal lead screw 55 and the upper column 2. Its main purpose is to convert the axial linear motion of the trapezoidal lead screw 55 into the rotational motion of the upper column 2 and to provide rotational support. The advantage of the upper joint 56 is that it contains a trapezoidal nut 562, which forms a threaded pair with the trapezoidal thread 553 of the trapezoidal lead screw 55, achieving precise transmission and self-locking functions. Furthermore, the upper joint 56 is connected to the upper column 2 via the upper rotating shaft 561, allowing the upper column 2 to rotate smoothly during the tilting process.

[0046] The upper joint 56 mainly includes an upper rotating shaft 561 and a trapezoidal nut 562. The internal thread of the trapezoidal nut 562 meshes with the trapezoidal thread 553 of the trapezoidal lead screw 55. When the trapezoidal lead screw 55 rotates, the trapezoidal nut 562 moves axially along the trapezoidal lead screw 55. The upper rotating shaft 561 is supported by the upper left bracket 51 and the upper right bracket 52 of the pitch-changing mechanism 5. This structure ensures that the upper joint 56, driven by the trapezoidal lead screw 55, can drive the upper column 2 to perform a tilting motion around the rotating shaft 4.

[0047] The lower joint 57 is another key component connecting the trapezoidal lead screw 55 to the lower column 1. Its main purpose is to provide lower support for the trapezoidal lead screw 55 and ensure that it does not bear radial bending loads during movement, thereby improving the service life and working efficiency of the fixing device. The lower joint 57 has the advantage of employing a rolling friction structure composed of a fixed bearing sleeve 572, a movable bearing sleeve 573, and steel balls 574. This design greatly improves the working efficiency of the pitch mechanism 5 and significantly reduces the physical exertion of operators when turning the handle 8, especially when the upper column 2 and the equipment mounted on it are heavy. Simultaneously, this rolling friction structure also provides automatic centering, allowing the trapezoidal lead screw 55 to float radially within the lower joint 57, effectively preventing damage to the trapezoidal lead screw 55 from radial bending loads and extending its service life.

[0048] The lower joint 57 mainly includes a lower rotating shaft 571, a fixed bearing sleeve 572, a movable bearing sleeve 573, steel balls 574, and a pressure plate 575. The lower rotating shaft 571 is connected to the trapezoidal lead screw 55 by a nut via a standard thread. The fixed bearing sleeve 572 and the movable bearing sleeve 573 are internally fitted with steel balls 574, forming rolling supports. The pressure plate 577 is used to prevent these components from scattering during assembly. The lower joint 57 is supported by the lower left bracket 53 and the lower right bracket 54 of the pitch mechanism 5, allowing the lower joint 57 to rotate around the axis of the support hole within the bracket.

[0049] The lock-on knob 6 and the movable nut 7 together constitute an auxiliary locking mechanism for reinforcing the connection under specific conditions. The main purpose of the movable nut 7 is to cooperate with the lock-on knob 6 to provide additional mechanical locking when the upper column 2 is in the vertical working position, enhancing the stability of the entire device. Its advantage lies in providing a simple and effective secondary locking mechanism, ensuring that the equipment will not accidentally tip over under normal operating conditions, thereby improving the operational safety and reliability of the equipment. When the upper column 2 needs to tip over, simply manually loosening the connection between the lock-on knob 6 and the movable nut 7 will release the lock, facilitating subsequent operations.

[0050] The movable nut 7 is typically a standard hexagonal nut, but its special feature lies in its installation position and mating method. The movable nut 7 is installed within the slotted bracket 58 of the pitch-changing mechanism 5. The slotted bracket 58 has a slotted hole, which restricts the opposite sides of the movable nut 7, preventing it from rotating freely, but allowing for a small range of movement along the length of the slotted hole. This design cleverly solves the alignment problem that may occur when the lock-lock knob 6 is rotated to the vertical position, making it easier to align and tighten the lock-lock knob 6 with the movable nut 7. To further facilitate alignment, a guide cone is designed on the lower column 1 to guide the lock-lock knob 6 accurately into the thread of the movable nut 7. The lock-lock knob 6 is connected to the movable nut 7 via threads; when tightened, the two form a tight fit, providing reinforcement. Positionally, the movable nut 7 and the lock-lock knob 6 are located on the side of the connection between the upper column 2 and the lower column 1, facilitating operation by personnel on the ground.

[0051] The limit nut 511 is a crucial safety component on the trapezoidal lead screw 55. Its primary purpose is to prevent the relative movement between the trapezoidal lead screw 55 and the trapezoidal nut 562 from exceeding a preset safe travel distance. Its advantage lies in providing a physical travel limit, effectively preventing the trapezoidal lead screw 55 from dislodging from the trapezoidal nut 562 due to improper operation or unexpected situations, thus avoiding a serious safety accident such as the sudden fall of the upper column 2 and the equipment mounted on it. This greatly improves the safety of the entire equipment fixing device, protecting both the equipment and the operators.

[0052] Two limit nuts 511 are typically used, installed at the upper thread 554 of the trapezoidal lead screw 55. These two limit nuts 511, through counter-rotation and mutual compression, create a reliable anti-loosening preload on the trapezoidal lead screw 55, ensuring it will not loosen during operation. When the trapezoidal nut 562 moves upwards along the trapezoidal lead screw 55 to its limit position, it contacts the limit nuts 511, thus preventing further movement and achieving the limiting function. This double-nut locking connection method is simple and reliable, and is an indispensable component for ensuring the safe operation of the device.

[0053] The principle is as follows: The working principle of this embodiment mainly revolves around the variable pitch mechanism 5 driving the upper column 2 to rotate. When it is necessary to install equipment on the upper column 2 or to maintain the installed equipment, the operator first operates from the ground. If the upper column 2 is in a vertical working position and is secured and locked by the non-detachable knob 6 and the movable nut 7, the operator must first manually loosen the connection between the non-detachable knob 6 and the movable nut 7 to release the secure locking state and prepare for the upper column 2 to tilt.

[0054] Subsequently, the operator attaches the crank handle 8 to the crank handle interface 551 at the lower end of the trapezoidal lead screw 55. By turning the crank handle 8, the trapezoidal lead screw 55 begins to rotate. Since the trapezoidal thread 553 of the trapezoidal lead screw 55 and the trapezoidal nut 562 in the upper joint 56 form a threaded pair, the rotation of the trapezoidal lead screw 55 will cause the trapezoidal nut 562 to move relative to the axial direction of the trapezoidal lead screw 55. This axial movement is transmitted to the upper column 2 through the upper joint 56 and the lower joint 57.

[0055] Specifically, the upper joint 56 and the lower joint 57 are supported by the upper left bracket 51, the upper right bracket 52, the lower left bracket 53, and the lower right bracket 54 of the pitch-changing mechanism 5, respectively. When the trapezoidal nut 562 moves on the trapezoidal lead screw 55, it causes relative displacement between the upper joint 56 and the upper column 2. Since the upper column 2 is hinged to the lower column 1 through the column connecting plate 3 and the rotating shaft 4, this displacement is converted into rotational motion of the upper column 2 around the rotating shaft 4. By continuously turning the crank handle 8, the upper column 2 can gradually fall from the vertical position to the lowest limit position, or gradually stand up from the lowest limit position to the vertical position.

[0056] Throughout the entire process of falling or standing up, the rolling friction structure composed of the fixed bearing sleeve 572, the movable bearing sleeve 573, and the steel ball 574 within the lower joint 57 plays a crucial role. It significantly improves the working efficiency of the pitch mechanism 5, reduces the physical exertion of operators, and automatically centers the mechanism, ensuring that the trapezoidal lead screw 55 does not bear radial bending loads, thereby extending the service life of the fixing device. Simultaneously, the threaded pair between the trapezoidal lead screw 55 and the trapezoidal nut 562 has excellent self-locking properties, allowing the upper column 2 to reliably maintain its current position at any pitch angle without the need for additional locking devices.

[0057] Furthermore, the limit nut 511 installed on the trapezoidal lead screw 55 plays a crucial safety protection role. When the trapezoidal nut 562 moves to the preset limit position, it will contact the limit nut 511, thereby preventing the relative movement between the trapezoidal lead screw 55 and the trapezoidal nut 562 from exceeding the safe travel, effectively preventing the trapezoidal lead screw 55 from dislodging from the nut and causing the equipment to fall. After the equipment installation or maintenance is completed, the operator can turn the crank handle 8 again to raise the upper column 2 to a vertical position, and tighten the non-disengaging knob 6 and the movable nut 7 to re-secure and lock the equipment, ensuring safe and stable operation. The entire work process allows for the installation, maintenance, and status switching of the equipment to be completed on the ground, greatly improving the convenience, safety, and efficiency of the operation.
