Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic quick mounting mechanism, and particularly relates to a tower crane hook camera magnetic quick mounting mechanism. BACKGROUND

[0002] In the field of modern construction, as an important vertical transportation equipment, the tower crane (tower crane) has an increasingly urgent need for operation safety monitoring. In order to real-time master the hook operation state and avoid the risk of hoisting blind area, installing a camera on the tower crane arm has become an industry standard. However, the traditional camera installation method generally uses bolt fastening or buckle connection, and such methods have significant drawbacks: the installation process needs to use tools such as wrenches for repeated adjustment, which is time-consuming, and the tool operation is not convenient in the high-altitude working environment, which has safety hazards; when disassembling and repairing, the bolts also need to be disassembled one by one, which is not only inefficient, but also easy to cause thread wear and affect the installation stability due to frequent disassembly and assembly.

[0003] In recent years, magnetic installation technology has been gradually applied to the field of rapid equipment assembly, which uses the magnetic force between permanent magnets to realize the rapid adsorption and fixation of components without complex fastening operation. However, the existing magnetic camera installation structure has many shortcomings: simply relying on magnetic adsorption, in the case of high-frequency vibration and strong wind of the tower crane, the camera is easy to displace or even fall off, which cannot meet the requirements of long-time stable work; the magnetic adsorption lacks mechanical limiting assistance, and the installation precision is difficult to guarantee, which is easy to cause the camera angle deviation and affect the monitoring picture quality; at the same time, the existing magnetic installation structure does not have the function of quick disassembly, and a large amount of time is needed to separate the magnetic components during maintenance, which has high maintenance cost.

[0004] Therefore, how to develop a dual protection structure integrating magnetic quick connection and mechanical stable locking to realize the quick installation, accurate positioning and reliable fixation of the camera on the tower crane arm, and at the same time meet the convenient disassembly and maintenance requirements, has become a technical problem to be solved. SUMMARY

[0007] Further explanation, the pulley is made of MC nylon material, and a brass shaft sleeve is embedded in the pulley.

[0008] Further explanation, the clamping assembly comprises a return spring, a top block and a roller, the top of each of the two clamp components is connected with the top block, the top blocks form a trapezoidal structure with inclined front and rear sides after being attached, the return spring is sleeved on the outside of the guide rod, the lower and upper ends of the return spring are fixedly connected with the bottom of the lower layer permanent magnet base and the inside of the n-shaped block respectively, the roller is rotatably connected to the middle of the bottom of the lower layer permanent magnet base, and the roller and the top block maintain a dynamic abutting relationship.

[0009] Further explanation, further comprising a triangular top rod, a compression spring, a sliding block, an arc-shaped clamping rod and a return spring, the triangular top rod is symmetrically and slidably connected to the front and rear sides of the n-shaped block, the triangular part of the triangular top rod extends above the top surface of the n-shaped block, the compression spring is connected between the bottom of the triangular top rod and the inside of the n-shaped block, the sliding block is slidably connected to the lower side of the triangular top rod, the arc-shaped clamping rod is rotatably connected to the inside of the sliding block, the curvature of the arc-shaped clamping rod is matched with the curvature of the outer surface of the clamp component, arc-shaped grooves are formed in positions corresponding to the arc-shaped clamping rod on the n-shaped block, and the arc-shaped clamping rod and the arc-shaped grooves form a sliding guide pair, and the return spring is connected between the sliding block and the triangular top rod.

[0010] Further explanation, further comprising a plurality of balls, and the inside surface of the arc-shaped clamping rod is uniformly arranged with the balls in an embedded structure.

[0011] Further explanation: It also includes a motor, gears, and tooth blocks. The motor is installed on the front right side of the n-type block, and the gear is connected to the output shaft of the motor. A tooth ring structure is set on the outer surface of the right end of the two clamps at the position corresponding to the gear. The tooth ring is composed of multiple spaced tooth blocks, and the distribution area of ​​the tooth blocks avoids the notch position of the clamps. The gears and tooth blocks mesh with each other.

[0012] To further explain, it also includes a locking block and a locking spring. The locking block is slidably connected at the notch of the clamp, and a locking spring is connected between the locking block and the inside of the clamp. The inclined surfaces of the two opposing locking blocks cooperate to form the guide inlet of the pulley.

[0013] To further explain, it also includes protruding rods.

[0014] Beneficial effects: 1. Pre-installation is achieved through the sliding fit between the I-beam and the I-frame. Combined with the magnetic adsorption between the upper permanent magnet and the lower permanent magnet base, the camera can be fixed without additional tools. When disassembling, it is only necessary to rotate the camera in the opposite direction and move it horizontally. Compared with the traditional bolt fixing method, it effectively improves efficiency.

[0015] 2. The lower permanent magnet base forms a magnetic coupling with the upper permanent magnet under the action of the return spring. At the same time, the rollers of the locking component cooperate with the inclined surface of the top block, which improves the overall locking force and can resist the vibration during tower crane operation.

[0016] 3. When the I-beam pushes the triangular top rod downward, the arc-shaped clamping rod fits against the outer surface of the clamping part, effectively increasing the contact area and static friction, thereby effectively preventing the circumferential movement of the n-type block.

[0017] 4. The motor drives the meshing of gears and gear blocks to achieve circumferential rotation of the camera, which can be used to check key angles such as the tower crane hoisting area and building interfaces according to usage requirements, and the adjustment is convenient and quick.

Detailed Implementation

[0029] Example: A magnetic quick-installation mechanism for a tower crane hook camera, such as... Figures 1-6As shown, the system includes a clamp 101, an n-shaped block 102, an I-beam frame 103, a camera 104, an I-beam 105, a pulley 108, a support rod 201, an upper permanent magnet 202, a guide rod 203, a lower permanent magnet base 204, and a locking assembly. The clamp assembly consists of two clamps 101, which are bolted to a pre-installed position on the tower crane boom 1. Guide grooves 106 are provided on the left and right sides of the clamps 101. When the two clamps 101 are closed, the corresponding guide grooves 106 form a ring-shaped guide structure. The n-shaped block 102 is inserted... Attached to the outside of the clamp 101, pulleys 108 are respectively mounted on the left and right sides of the upper part of the n-shaped block 102 via a rotating joint. The pulleys 108 precisely engage with the guide groove 106, enabling the n-shaped block 102 to slide smoothly along the annular guide groove 106. Notches 107 are pre-reserved on the left and right sides of the upper end of the two clamps 101. The size of these notches 107 is adapted to the pulleys 108, ensuring that the pulleys 108 can smoothly pass through the notches 107 and enter the guide groove 106 during the installation of the n-shaped block 102. The pulleys 108 are made of MC nylon material and have brass shafts embedded inside. The MC nylon bushing handles external friction and reduces weight, while the brass bushing addresses internal rotational accuracy and heat dissipation. Together, they enable the pulley 108 to withstand frequent quick-assembly and disassembly operations while maintaining stable performance under complex conditions such as tower crane vibration and load variations. The top of the n-block 102 is connected to an I-beam frame 103, and the bottom of the camera 104 is connected to an I-beam component 105. The I-beam component 105 and the I-beam frame 103 form a sliding guide pair. The initial assembly of the camera 104 and the n-block 102 is achieved through their sliding interlocking. Four support rods 201 are connected in a square array on the lower side of the 05. An upper permanent magnet 202 is slidably installed between the four support rods 201. The bottom surface of the upper permanent magnet 202 is flush with the bottom surface of the I-shaped part 105. Four guide rods 203 are correspondingly arranged on the upper side of the n-shaped block 102. A lower permanent magnet base 204 is slidably installed between the four guide rods 203. The top surface of the lower permanent magnet base 204 is flush with the top surface of the n-shaped block 102, and the lower permanent magnet base 204 and the upper permanent magnet 202 form a magnetic coupling. A clamping component is provided on the clamping part 101.

[0030] like Figures 5-6 As shown, the positioning assembly includes a reset spring 205, a top block 206, and a roller 207. The top of each of the two clamping parts 101 is welded with a top block 206. After the top blocks 206 are fitted together, they form a trapezoidal structure with inclined surfaces on the front and back sides. The guide rod 203 is fitted with a reset spring 205 on its outer side. The upper and lower ends of the reset spring 205 are fixedly connected to the bottom of the lower permanent magnet base 204 and the inside of the n-shaped block 102, respectively. The roller 207 is rotatably connected to the middle of the bottom of the lower permanent magnet base 204. The roller 207 maintains a dynamic contact relationship with the top block 206, so that the reset spring 205 is in a stretched state, providing a reset pulling force for the lower permanent magnet base 204.

[0031] During the installation of camera 104, the clamp 101 is first fixed to the designated position on the tower crane boom 1. Then, the n-shaped block 102 is inserted into the clamp 101 from top to bottom. The pulley 108 on the n-shaped block 102 precisely aligns with the notch 107 of the clamp 101. During insertion, the roller 207 inside the n-shaped block 102 contacts the top block 206. The top block 206 abuts against the roller 207, while the n-shaped block 102 continues to move downward, causing the return spring 2 to... 05 Gradually stretch, the lower permanent magnet base 204 will move and become flush with the top surface of the n-shaped block 102. After the n-shaped block 102 is fixed, align the I-shaped component 105 on the camera 104 with the I-shaped frame 103, and slide the camera 104 horizontally so that the I-shaped component 105 and the I-shaped frame 103 can slide and interlock, completing the pre-installation of the camera 104. At this time, the upper permanent magnet 202 and the lower permanent magnet base 204 will achieve initial adsorption due to mutual magnetic attraction. Subsequently, the camera 104 is rotated 180 degrees around the circumference of the clamp 101. The pulley 108 rolls in the guide groove 106 and is offset from the notch 107, forming a circumferential limit to prevent the n-shaped block 102 from axially disengaging from the clamp 101. During the rotation, the roller 207 gradually disengages from the top block 206. Under the tension of the return spring 205, the lower permanent magnet base 204 and the roller 207 slide inward along the guide rod 203. Due to the magnetic cooperation between the lower permanent magnet base 204 and the upper permanent magnet 202, the upper permanent magnet 202 will be driven to slide synchronously along the support rod 201. The upper permanent magnet 202 is embedded inside the n-shaped block 102, realizing the mechanical and magnetic dual locking of the I-beam 105 and the n-shaped block 102, significantly improving the stability of the camera 104 after installation. After installation, the camera 104 accurately faces the working area. When it is necessary to disassemble the camera 104, rotate the camera 104 180 degrees in the opposite direction so that the pulley 108 and the notch 107 of the clamp 101 are aligned again. The roller 207 re-contacts the top block 206. Under the guidance of the inclined surface of the top block 206, the roller 207 drives the lower permanent magnet base 204 to move outward, while pushing the upper permanent magnet 202 to slide back along the support rod 201 until the bottom surface of the upper permanent magnet 202 is flush with the bottom surface of the I-beam 105, thus releasing the latch. Then, move the camera 104 backward along the sliding direction of the I-beam frame 103 so that the I-beam 105 is separated from the I-beam frame 103, thus completing the disassembly of the camera 104. The upper permanent magnet 202 and the lower permanent magnet base 204 are demagnetized. Finally, lift the n-shaped block 102 upward to remove it from the clamp 101, thus completing the disassembly operation of the entire quick-release mechanism.

[0032] Example 2: Based on Example 1, such as Figures 7-9As shown, it also includes a triangular push rod 301, a compression spring 302, a slider 303, an arc-shaped retaining rod 304, a return spring 306, and a ball bearing 4. The triangular push rod 301 is symmetrically slidably connected to the front and rear sides of the n-shaped block 102, with its triangular portion extending above the top surface of the n-shaped block 102. A compression spring 302 connects the bottom of the triangular push rod 301 to the interior of the n-shaped block 102, providing upward elastic support for the triangular push rod 301. A slider 303 is slidably connected to the lower side of the triangular push rod 301, and an arc-shaped retaining rod 304 is rotatably connected to the inner side of the slider 303. The curvature of the arc-shaped retaining rod 304 matches the curvature of the outer surface of the retaining member 101. Arc-shaped grooves 305 are formed on the n-shaped block 102 at positions corresponding to the arc-shaped retaining rod 304. The arc-shaped retaining rod 304 and the arc-shaped groove 305... 5 forms a sliding guide pair. A return spring 306 is connected between the slider 303 and the triangular push rod 301. When the I-beam 105 slides with the I-beam frame 103, the bottom surface of the I-beam 105 contacts the inclined surface of the triangular push rod 301. The inclined surface force pushes the triangular push rod 301 downward. The inner side of the arc-shaped retaining rod 304 adopts an embedded structure to evenly arrange multiple balls 4. When the arc-shaped retaining rod 304 surrounds the outer surface of the retaining member 101, the balls 4 form rolling contact with the outer surface of the retaining member 101. During the process of the n-shaped block 102 driving the arc-shaped retaining rod 304 to rotate around the retaining member 101, the balls 4 convert sliding friction into rolling friction, effectively reducing frictional resistance, making the rotation operation smoother, and reducing the wear of the arc-shaped retaining rod 304 and the surface of the retaining member 101.

[0033] like Figure 10 As shown, it also includes a motor 501, a gear 502, and a toothed block 503. The motor 501 is mounted on the front right side of the n-shaped block 102 by screws. The output shaft of the motor 501 is connected to the gear 502 via a coupling. A gear ring structure is set on the outer surface of the right end of the two clamping parts 101 at the position corresponding to the gear 502. The gear ring is composed of multiple spaced toothed blocks 503, and the distribution area of ​​the toothed blocks 503 avoids the notch 107 position of the clamping part 101. The gear 502 and the toothed blocks 503 mesh with each other. During the installation of the camera 104, the motor 501 is in a de-energized state. When the n-shaped block 102 rotates circumferentially along the clamping part 101, the gear 502 moves accordingly and meshes with the toothed blocks 503. When the motor 501 is off, its output shaft will idle. When the camera 104 needs to be adjusted, the remote control system sends an electrical signal to the motor 501 drive module. The motor 501 starts and drives the gear 502 to rotate. Through the meshing of the gear 502 and the toothed block 503, the n-shaped block 102 is forced to rotate circumferentially along the clamp 101, thereby driving the camera 104 to rotate synchronously to the target angle. This allows for viewing the tower crane's perspective when hoisting buildings, or checking the surrounding environment. After use, the motor 501 drives the camera 104 back to its initial working position (i.e., downward position), and the motor 501 automatically shuts off.

[0034] During the installation of camera 104, when the I-beam 105 slides along the I-beam frame 103, regardless of whether the sliding direction is from front to back or from back to front, the I-beam 105 will contact the triangular top rod 301 and push it downward. The compression spring 302 is compressed and stores elastic potential energy. During the downward movement of the triangular top rod 301, the movement of the triangular top rod 301 will push the arc-shaped retaining rod 304 to slide along the arc-shaped groove 305 through the slider 303. The slider 303 will then slide outward along the triangular top rod 301, and the return spring 306 will be compressed, ultimately causing the arc-shaped retaining rod 304 to... The n-shaped block 102 fits tightly against the outer surface of the clamp 101, thereby increasing the contact area between the clamp 101 and the n-shaped block 102, improving the friction and connection tightness between them. When the camera 104 needs to be disassembled, the I-beam 105 separates from the I-beam frame 103, relieving the pressure on the triangular top rod 301. The compression spring 302 releases elastic potential energy to push the triangular top rod 301 to move upward and reset. The slider 303 slides inward under the action of the return spring 306, causing the arc-shaped clamp 304 to slide in the opposite direction along the arc-shaped groove 305 and retract, so that the n-shaped block 102 returns to the detachable state.

[0035] like Figure 4 As shown, it also includes a locking block 601 and a locking spring 602. The locking block 601 is slidably connected to the notch 107 of the clamp 101. The locking block 601 and the inside of the clamp 101 are connected by the locking spring 602. The inclined surfaces of the two opposing locking blocks 601 cooperate to form a guide entrance, which facilitates the pulley 108 to enter the notch 107. When the n-type block 102 is installed, the pulley 108 is released from the inclined surface of the locking block 601 and pushes the locking block 601 to move outward, compressing the locking spring 602. After the pulley 108 has completely passed through the locking block 601, the locking spring 602 resets so that the locking block 601 blocks the pulley 108 from exiting the path, preventing the n-type block 102 from accidentally disengaging. When disassembling, the locking block 601 must be manually pushed outward to release the blockage of the notch 107 before the n-type block 102 can be taken out upward.

[0036] like Figure 4 As shown, it also includes a protruding rod 701. The upper side of the rear side of the front clamp 101 has two slots 702, and two protruding rods 701 are welded to the corresponding positions on the lower side. The structure of the front side of the rear clamp 101 is complementary to that of the front clamp 101. The upper side is provided with a protruding rod 701, and the lower side is provided with a slot 702. During installation, the front and rear clamps 101 are pre-positioned by the engagement of the protruding rods 701 and the slots 702, and then the clamps are fastened with bolts to form a complete clamp assembly.
