Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a vibration-resistant support structure for a visual building construction tower crane hook camera. Background Technology

[0002] In the construction industry, tower cranes are core lifting equipment, and real-time monitoring of their hook operation area is crucial for construction safety and efficiency. Currently, the industry commonly uses cameras installed on the tower crane boom to achieve visual monitoring of the hook. However, due to the high-frequency vibrations that occur during tower crane operation (such as vertical impacts when lifting heavy objects, centrifugal swaying when the boom rotates, and resonance in strong winds), cameras are easily affected by vibrations, resulting in blurry, shaky images, and even problems such as lens shift and loose parts. In severe cases, continuous vibration may damage the camera, affecting the continuity of monitoring.

[0003] The existing camera support structure has obvious limitations in its shockproof design: some use a single spring for shock absorption, which can only buffer low-frequency vibrations in the vertical direction and has poor attenuation effect on horizontal and high-frequency vibrations; some use rigid connections with rubber pads for shock absorption, which is simple in structure, but the rubber is prone to aging, and the shockproof performance drops significantly after long-term use, and it cannot adapt to the complex and ever-changing vibration conditions of tower cranes. Summary of the Invention

[0004] To overcome the shortcomings mentioned in the background art, the present invention provides a shock-resistant support structure for a visual construction tower crane hook camera.

[0005] The technical implementation scheme of this invention is as follows: A vibration-resistant support structure for a visual construction tower crane hook camera includes a tower crane boom, a mounting frame, a connecting plate, guide rods, a buffer spring, a fixed frame, a sliding frame, a camera, and mounting components. The mounting frame is snapped and fixed to the tower crane boom. The connecting plate is mounted on the mounting frame via the mounting components. Guide rods are slidably inserted through the four corners of the connecting plate. The bottom ends of the guide rods are all fixed to the fixed frame. Buffer springs are sleeved on the guide rods. The upper and lower ends of the buffer springs are respectively connected to the top surface of the fixed frame and the bottom surface of the connecting plate. A sliding frame is slidably connected to the bottom of the fixed frame. The camera is rotatably mounted via the mounting components. At the bottom of the sliding frame, there are also X-shaped folding frames, sliders, piston cylinders, air rods, and return springs. The top corner of the fixed frame and the bottom corner of the connecting plate are both provided with grooves. Sliders are slidably embedded in the grooves. X-shaped folding frames are hinged between the front sliders and between the rear sliders. Piston cylinders are fixedly connected to the connecting plate and the fixed frame near the sliders. Air rods are slidably and sealed inside the piston cylinders. The outer end of the air rods is fixedly connected to the corresponding slider. A return spring is connected between the air rods and the inner wall of the piston cylinders. The inner end of the piston cylinders is open and closed by the air rods. Air holes are provided on the outer side of the top of the piston cylinders.

[0006] More preferably, a damping structure is provided at the sliding connection between the guide rod and the connecting plate, and the damping structure is a high-viscosity damping grease filled at the sliding connection between the guide rod and the connecting plate.

[0007] More preferably, the piston cylinder is made of seamless steel pipe with a precision polished inner wall.

[0008] More preferably, the mounting assembly includes positioning blocks, locking blocks, pull rods, and long springs. Positioning blocks are symmetrically mounted on the top of the connecting plate. The mounting frame is U-shaped. The positioning blocks slide and adapt to the U-shaped groove of the mounting frame. Locking blocks are slidably connected to the front and rear sides of the upper side of the positioning blocks. Long springs are connected between two locking blocks inside the positioning blocks. Pull rods are connected to the outer walls of the locking blocks. Several locking slots are vertically opened on the front and rear side walls of the U-shaped groove of the mounting frame. The locking blocks are locked into the locking slots.

[0009] More preferably, it also includes support blocks, arc-shaped pipes, semi-circular piston rods, and fixing components. Support blocks are symmetrically connected to both sides of the sliding frame, and arc-shaped pipes are connected to the bottom of each support block. A semi-circular piston rod is slidably and sealed between the two arc-shaped pipes on the front side, and a semi-circular piston rod is also slidably and sealed between the two arc-shaped pipes on the rear side. Fixing components are installed on both sides of the lower part of the camera, and the fixing components are fixedly sleeved with the middle of the semi-circular piston rods on the adjacent side.

[0010] More preferably, it also includes a delivery pipe, a circulation pipe, a piston plate, and a return spring. The delivery pipe is connected through the inner sides of the two support blocks on the left, and another delivery pipe is connected through the inner sides of the two support blocks on the right. The two ends of the delivery pipe are connected to the corresponding arc-shaped pipes. The middle of the delivery pipe is connected to the circulation pipe through a connector. The inner end of the circulation pipe passes through the fixed frame through a sealing connector. The piston plates are symmetrically slidably connected inside the fixed frame. The inner end of the circulation pipe passes through the corresponding piston plate and is fixedly connected to it. The outer side of the piston plate is connected to the inner wall of the fixed frame through a return spring. The chamber between the two piston plates in the fixed frame and the inside of the arc-shaped pipe are filled with hydraulic oil.

[0011] More preferably, it also includes rubber retaining beads and retaining springs. Rubber retaining beads are slidably connected to both ends of the semi-ring piston rod at intervals along the circumference. A retaining spring is connected between the rubber retaining beads and the inside of the semi-ring piston rod. Several retaining holes are opened at intervals on the inner wall of the arc-shaped tube at positions corresponding to the rubber retaining beads. The rubber retaining beads are inserted into the retaining holes at corresponding heights.

[0012] More preferably, it also includes a positioning cylinder, a conical top rod, a trapezoidal block, and a compression spring. A fixing hole is opened at the top of the tower crane boom, and a positioning cylinder is connected to the middle of the mounting frame. The positioning cylinder is inserted into the fixing hole. Trapezoidal blocks are slidably connected in four directions inside the positioning cylinder. A compression spring is connected between the trapezoidal block and the inside of the positioning cylinder. A conical top rod is connected to the middle of the top of the connecting plate. A through hole is opened at the bottom of the tower crane boom for the conical top rod to pass through. The conical surface of the conical top rod forms a contact fit with the trapezoidal block.

[0013] Compared with the prior art, the present invention has the following advantages: 1. By using the damping structure of the buffer spring and guide rod, the pneumatic buffering of the piston cylinder and air rod in combination with the X-shaped folding frame, the hydraulic damping of the semi-ring piston rod and the arc-shaped through pipe, and the mechanical damping of the rubber ball and the locking hole, a multi-directional and multi-level composite vibration reduction system is formed, which can effectively attenuate the vertical, horizontal and multi-angle swing vibrations generated during the operation of the tower crane, ensuring that the camera captures clear and stable images and providing reliable image data for construction monitoring.

[0014] 2. The locking block and slot bevel structure of the mounting components enable quick and easy locking and fixing of the connecting plate and mounting bracket; during disassembly, simply pulling the lever releases the lock, making operation convenient. Meanwhile, the auxiliary fixing structure of the positioning cylinder and conical top rod ensures installation stability without increasing the complexity of assembly and disassembly, significantly reducing the time and cost of camera inspection and maintenance.

[0015] 3. The double fixing of the mounting frame and the tower crane boom (with locking blocks and slots + trapezoidal block locking) and the fit between the positioning cylinder and the fixing holes ensure that the device is not easily loosened or detached under complex working conditions such as strong winds at high altitudes and frequent start-ups and shutdowns of the tower crane. The sealed sliding and elastic connection design between various components combines buffering and rigid support capabilities, extending the service life of the equipment.

Detailed Implementation

[0027] Example: A vibration-resistant support structure for a visual construction tower crane hook camera, such as... Figures 1-8As shown, the system includes a tower crane boom 1, a mounting frame 101, a connecting plate 102, guide rods 103, a buffer spring 104, a fixing frame 105, a sliding frame 106, a camera 107, an X-shaped folding frame 201, a slider 202, a piston cylinder 203, a pneumatic rod 204, a return spring 205, and mounting components. The mounting frame 101 is detachably snapped onto the tower crane boom 1. The connecting plate 102 is mounted on the mounting frame 101 via the mounting components. Guide rods 103 slide through each of the four corners of the connecting plate 102. A damping structure is provided at the sliding connection between the guide rods 103 and the connecting plate 102. The damping structure is filled with... The high-viscosity damping grease at the sliding connection between the guide rod 103 and the connecting plate 102 ensures smooth sliding of the guide rod 103 while effectively attenuating vibration energy. A fixed frame 105 is fixedly connected to the bottom of all four guide rods 103. A buffer spring 104 is sleeved on each guide rod 103, with its upper and lower ends connected to the top surface of the fixed frame 105 and the bottom surface of the connecting plate 102, respectively. A sliding bracket 106 is slidably connected to the bottom of the fixed frame 105 in the left-right direction. A camera 107 is rotatably mounted on the bottom of the sliding bracket 106 via a mounting component. The camera 107 captures images through its bottom lens. The four top surfaces of the fixed frame 105 are also connected to the bottom. Grooves are provided at the four corners of the lower end of the connecting plate 102, and sliders 202 are slidably embedded in the grooves. An X-shaped folding frame 201 is hinged between the four sliders 202 on the front side, and an X-shaped folding frame 201 is also hinged between the four sliders 202 on the rear side. The two X-shaped folding frames 201 are respectively located on the front and rear sides of the connecting plate 102 and the fixing frame 105. A piston cylinder 203 is fixedly connected to the connecting plate 102 and the fixing frame 105 near the sliders 202. A gas rod 204 is slidably and sealed inside the piston cylinder 203. The outer end of the gas rod 204 is fixedly connected to the corresponding slider 202. The piston cylinder 203 is made of seamless steel tubing. The inner wall of the piston cylinder 203 is precision polished to ensure the sealing and sliding accuracy of the air rod 204. A return spring 205 is connected between the air rod 204 and the inner wall of the piston cylinder 203 to provide buffering force. The inner end of the piston cylinder 203 is open and closed by the air rod 204. Through grooves are opened on the connecting plate 102 and the fixing frame 105 at the position corresponding to the inner port of the piston cylinder 203, so that the inner port of the piston cylinder 203 is connected to the outside. An air hole 206 is opened on the outer side of the top of the piston cylinder 203. Through grooves are also opened on the connecting plate 102 and the fixing frame 105 at the position corresponding to the air hole 206, so that the air hole 206 in the piston cylinder 203 is connected to the outside.

[0028] like Figure 2 and Figures 6-8As shown, the mounting assembly includes a positioning block 301, a locking block 302, a pull rod 303, and a long spring 305. The positioning blocks 301 are symmetrically mounted on the top of the connecting plate 102 by screws. The mounting bracket 101 is U-shaped. The positioning blocks 301 are slidably adapted to the U-shaped groove of the mounting bracket 101. The locking blocks 302 are slidably connected to the front and rear sides of the upper side of the positioning block 301. A long spring 305 is connected between the two locking blocks 302 inside the positioning block 301. The pull rod 303 is connected to the outer side wall of the locking blocks 302. Several slots 304 are vertically opened on the front and rear side walls of the U-shaped groove of the mounting bracket 101. The outer side of the locking block 302 is provided with a guide slope. The top surface of the slot 304 is provided with a mating slope adapted to the locking block 302. The locking blocks 302 are inserted into the slots 304 to fix the positioning blocks 301.

[0029] When using this device, the mounting bracket 101 is snapped and fixed in the preset position of the tower crane boom 1. The connecting plate 102 is moved so that the positioning block 301 is aligned with the U-shaped groove of the mounting bracket 101. When the positioning block 301 drives the locking block 302 to move upward, the guide slope of the locking block 302 contacts the mounting bracket 101 and is forced to move inward. The long spring 305 undergoes elastic deformation and stores force. When the locking block 302 is aligned with the locking groove 304, the locking block 302 is pushed outward into the locking groove 304 under the reset action of the long spring 305. The locking block 302 and the locking groove 304 are then used to achieve the desired effect. The inclined surface of 4 allows the locking block 302 to move smoothly upwards past the locking slot 304 until the positioning block 301 reaches the target position, completing the installation of the camera 107. After locking, the locking block 302, due to its flat bottom surface, cannot move downwards to ensure stability. The bottom lens of the camera 107 is aimed at the tower crane hook area for real-time shooting. When the tower crane boom 1 moves, the camera 107 is subjected to vertical forces. The buffer spring 104 provides elastic buffering for the fixed frame 105 and the camera 107. The guide rod 103 slides along the connecting plate 102, preventing... The damping structure provides damping resistance to attenuate vibration energy. Simultaneously, the X-shaped folding frame 201 unfolds or retracts. When unfolded, the slider 202 drives the air rod 204 to slide outward along the piston cylinder 203. The air rod 204 compresses the air inside the piston cylinder 203 and discharges it through the air hole 206 and the corresponding through slot. External air enters through the inner end of the piston cylinder 203 and the corresponding through slot. When the X-shaped folding frame 201 retracts, the slider 202 moves inward, and the air rod 204 compresses the air inside the piston cylinder 203 and discharges it through the inner port. External air enters through the air hole. 206 enters, the sealed sliding fit between the gas spring 204 and the piston cylinder 203 provides damping buffer for the X-shaped folding frame 201, and the return spring 205 effectively eliminates the vertical vibration force. When the camera 107 needs to be disassembled for inspection and maintenance, pull the lever 303 to move the locking block 302 inward and disengage it from the slot 304. The long spring 305 is then compressed, and the locking block 302 and the slot 304 are disengaged, so the camera 107 can be removed. After releasing the lever 303, the long spring 305 drives the locking block 302 and the lever 303 to return to their original positions.

[0030] Example 2: Based on Example 1, such as Figures 1-3 and Figure 9 As shown, it also includes a support block 401, an arc-shaped through pipe 402, a semi-ring piston rod 403, and a fixing member 404. The front and rear side walls of the sliding frame 106 are symmetrically connected to the support blocks 401 by bolts. The bottom of the support blocks 401 is connected to the arc-shaped through pipe 402. The semi-ring piston rod 403 is sealed and slidably connected between the two arc-shaped through pipes 402 on the front side, and the semi-ring piston rod 403 is also sealed and slidably connected between the two arc-shaped through pipes 402 on the rear side. The fixing member 404 is installed on the front and rear side walls of the lower part of the camera 107. The fixing member 404 is fixedly sleeved with the middle of the semi-ring piston rod 403 on the adjacent side. The rotation arc of the camera 107 is adapted to the sliding arc of the semi-ring piston rod 403 along the arc-shaped through pipe 402.

[0031] like Figure 2 and Figure 9 As shown, it also includes a delivery pipe 501, a circulation pipe 502, a piston plate 503, and a return spring 504. The delivery pipe 501 is connected through the inner side of the two support blocks 401 on the left, and another delivery pipe 501 is connected through the inner side of the two support blocks 401 on the right. The front and rear ends of the delivery pipe 501 are connected to the corresponding arc-shaped through pipes 402 on the same side. The middle part of the delivery pipe 501 is connected to the circulation pipe 502 through a connector. The inner end of the circulation pipe 502 passes through the fixed frame 105 through a sealing connector and can slide along the left and right direction of the fixed frame 105. The piston plate 503 is symmetrically slidably connected to the left and right sides inside the fixed frame 105. The inner end of the circulation pipe 502 passes through the corresponding piston plate 503 and is fixedly connected to it to achieve synchronous movement. Two return springs 504 are connected between the outer side of the piston plate 503 and the inner wall of the fixed frame 105. The chamber between the two piston plates 503 and the inside of the arc-shaped through pipe 402 in the fixed frame 105 are filled with hydraulic oil.

[0032] When the camera 107 is working, its rotating connection structure with the sliding frame 106 provides the camera 107 with a certain angular adjustment margin, which can avoid rigid damage caused by vibration. When the camera 107 is vibrating, the fixing part 404 drives the semi-ring piston rod 403 to slide along the arc-shaped pipe 402. The sealing cooperation between the semi-ring piston rod 403 and the arc-shaped pipe 402 forms hydraulic damping. The semi-ring piston rod 403 squeezes the hydraulic oil in the arc-shaped pipe 402, so that the oil enters the circulation pipe 502 through the delivery pipe 501 to achieve directional flow. As the vibration direction of the camera 107 changes, the swing direction of the semi-ring piston rod 403 changes accordingly, and the flow direction of the hydraulic oil switches synchronously. The viscous resistance of the hydraulic oil further attenuates the swing energy. When the device is subjected to left-right vibration force, the camera 107 drives the sliding frame 106 to slide left and right along the fixed frame 105. The circulation pipe 502 simultaneously drives the piston plate 503 to slide within the fixed frame 105. The return spring 504 undergoes elastic deformation and provides buffering force. The piston plate 503 pushes the hydraulic oil within the fixed frame 105 to flow left and right. By utilizing the incompressibility and flow resistance of the hydraulic oil, a two-way hydraulic buffer structure is formed. Combined with the return spring 504, it achieves efficient attenuation of left-right vibration, ultimately achieving a multi-angle, all-round composite vibration reduction effect.

[0033] like Figure 10 As shown, it also includes rubber retaining beads 601 and retaining springs 602. Four rubber retaining beads 601 are slidably connected to the left and right ends of the semi-ring piston rod 403 at circumferential intervals. A retaining spring 602 connects the rubber retaining beads 601 to the interior of the semi-ring piston rod 403. Several retaining holes 603 are spaced along the length of the inner wall of the arc-shaped tube 402 at positions corresponding to the rubber retaining beads 601. The rubber retaining beads 601 are engaged in the retaining holes 603 at corresponding heights. When the semi-ring piston rod 403 moves along the arc-shaped tube 402... During internal sliding, the engagement of the rubber ball 601 and the locking hole 603 increases the sliding resistance between them. When the sliding force is large enough, it will squeeze the rubber ball 601 inward into the semi-ring piston rod 403, and the locking spring 602 will be compressed accordingly. When the rubber ball 601 is aligned with the next locking hole 603, it will quickly pop outward and lock into the locking hole 603 under the reset action of the locking spring 602. The locking holes 603 are distributed along the length direction, which can effectively enhance the sliding resistance of the semi-ring piston rod 403.

[0034] like Figures 6-9As shown, it also includes a positioning cylinder 701, a conical top rod 702, a trapezoidal block 703, and a compression spring 704. A fixing hole is opened at the top of the tower crane boom 1. The positioning cylinder 701 is connected to the middle of the mounting frame 101. The positioning cylinder 701 is inserted into the fixing hole. Trapezoidal blocks 703 are slidably connected in the four directions of front, back, left, and right inside the positioning cylinder 701. A compression spring 704 is connected between the trapezoidal block 703 and the inside of the positioning cylinder 701. The inner and outer sides of the trapezoidal block 703 are both inclined structures. A conical top rod 702 is welded to the middle of the top of the connecting plate 102. A through hole is opened at the bottom of the tower crane boom 1 for the conical top rod 702 to pass through. The conical surface of the conical top rod 702 forms a contact fit with the trapezoidal block 703. In the initial state, the connecting plate 102 and the mounting frame 101 are in a preliminary installation state, and the outer end of the trapezoidal block 703 is aligned with the inner top surface of the tower crane boom 1.

[0035] When installing the camera 107, the mounting bracket 101 is first fitted onto the tower crane boom 1, ensuring that the positioning cylinder 701 is inserted into the fixing hole. Then, the connecting plate 102 is brought close to the mounting bracket 101 from bottom to top, so that the positioning block 301 gradually moves upward through the cooperation of the locking block 302 and the locking groove 304. The conical top rod 702 moves upward along the through hole on the tower crane boom 1. When the conical top rod 702 contacts the inner inclined surface of the trapezoidal block 703, it will push the trapezoidal block 703 to move outward. The compression spring 704 is compressed accordingly, and the trapezoidal block 703 moves outward and is inserted into the tower crane boom 1, thereby locking the inner top surface of the tower crane boom 1. At the same time, the positioning block 301 is inserted into the locking groove 304 through the locking block 302, completing the installation and fixing of the connecting plate 102 and the camera 107. The design of the trapezoidal block 703 can further improve the stability of the connecting plate 102 after installation, and at the same time, it can reinforce the mounting frame 101. When the connecting plate 102 is disassembled, the control block 302 is first disengaged from the slot 304, and then the connecting plate 102 and the positioning block 301 are pushed down, so that the conical top rod 702 is disengaged from the trapezoidal block 703. The compression spring 704 then drives the trapezoidal block 703 to move inward and disengage from the inside of the tower crane boom 1, and the mounting frame 101 can be removed from the tower crane boom 1.
