Description

Technical Field

[0001] This invention relates to the field of surveillance equipment installation technology, specifically to a sliding track-type convenient disassembly and assembly camera fixing device and method for the opening and closing machine room. Background Technology

[0002] As the core area of ​​water conservancy hubs and pumping stations, the gate hoist room has strict requirements for the monitoring and management of the internal equipment operation. A reasonable camera installation position can cover the working area, improve the monitoring field of view, and ensure the safe operation of the equipment. The traditional method of fixing cameras is mainly to fix them directly to the high-altitude wall with expansion bolts and brackets. Although the operation is simple, it has problems such as difficult maintenance and repair, high risk of working at height, and low work efficiency. Therefore, in order to facilitate the maintenance and replacement of equipment, lifting and fixing devices specifically designed for high-altitude monitoring equipment have been widely used.

[0003] Currently, camera fixed lifting devices on the market usually achieve the vertical movement of the equipment through related mechanisms. The principle is mostly based on electric winch traction, pulley rope or rod drive. These devices can lower the camera from a high place to a low place to complete the maintenance work, avoiding the dangers of manually building scaffolding or climbing.

[0004] While existing camera lifting and fixing devices have made progress in terms of ease of maintenance and safety, several shortcomings remain. First, when assembling and connecting cameras, existing devices lack precise lateral limiting and guiding structures. Operators, with obstructed vision, rely on feel to insert connectors, resulting in bent or broken pins or damaged seals. Second, existing devices lack automatic and reliable mechanical parking locks after being raised to the correct position. Prolonged suspension due to their own weight can lead to slippage and falls due to fatigue of components or loosening of latches, posing a safety hazard. Furthermore, existing lifting devices often rely on electric equipment or simple rope traction, making them unable to operate normally for lifting and adjustment during power outages. The fixed dimensions of the mounting base also make them incompatible with different camera sizes, and the exposed connecting cables are prone to snagging and breakage during lifting operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sliding track-type convenient disassembly and assembly method for fixing cameras in the hoisting and closing room, which solves the problems of existing high-altitude cameras having damaged pins due to blind plugging in power, lack of automatic mechanical locking during lifting and falling, and reliance on electrical energy and damage to cables.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sliding track-type convenient disassembly and assembly camera fixing device for a gate control room, comprising:

[0007] The main slide rail is used for wall-mounted support of the overall device and for guiding the internal lifting mechanism. It provides a vertical support foundation by fitting against the wall and uses the inner wall to physically limit the sliding trajectory of the internal components, preventing the camera from tilting laterally during lifting.

[0008] The chain drive mechanism is located inside the main slide rail and is used to smoothly adjust the height of the internal slider by manual drive. It uses the mechanical meshing of gears and chains to convert the manual rotation action of the ground operator into a linear lifting motion at a height, so that the operator can complete the fixed-point displacement of the high-altitude equipment from the ground and eliminate the need for high-altitude operation steps.

[0009] The high-altitude locking mechanism is located at the top inside of the main slide rail. It is used to lock the chain drive mechanism after the height adjustment is completed to prevent it from falling due to gravity. The mechanical locking structure automatically engages the gap of the transmission components when the gear stops rotating, thus physically blocking the reverse slippage phenomenon caused by gravity on the transmission components.

[0010] The hollow adapter mechanism is used to place and clamp cameras of different sizes, while hiding the camera's connecting cable inside. The adjustable clamping structure is compatible with camera bases of various sizes, and the internal cavity isolates the cable from the external environment, preventing the cable from being pulled and broken by outdoor wind at high altitudes.

[0011] The lifting bracket mechanism is located between the chain drive mechanism and the hollow adapter mechanism. It is used to support the hollow adapter mechanism and cooperate to complete blind plug-in power connection and mechanical locking. Relying on the limiting of the guide pin and the linear push-pull action, the power connection pin and the female seat are axially aligned and inserted, avoiding the bending of the pin in blind environment and improving the efficiency of high-altitude power connection and disassembly.

[0012] Preferably, the inner wall of the main slide rail is provided with a central guide groove, the chain drive mechanism includes an upper sprocket and a lower sprocket, a drive chain is driven between the upper sprocket and the lower sprocket, a hand crank is fixedly connected to the front surface of the lower sprocket, a drive traction slider is slidably connected inside the central guide groove, a fixing plate is fixedly connected to the front surface of the drive traction slider, and the rear surface of the fixing plate is fixedly connected to the front surface of the drive chain.

[0013] Preferably, the high-altitude locking mechanism includes a locking housing, a stop block fixedly connected inside the locking housing, a swing plate movably connected to the locking housing via a rotating shaft, an inclined plate fixedly connected to the bottom of the swing plate, the inclined plate correspondingly contacting the stop block, the end of the swing plate engaging with the teeth of the upper sprocket, a push block slidably connected inside the locking housing, one end of the push block extending out of the locking housing and fixedly connected to an insert plate, the end of the insert plate correspondingly engaging with a link of the transmission chain.

[0014] Preferably, the hollow adapter includes a cable box, the inside of which is provided with a cable routing groove, and the upper surface of the cable box is slidably connected to both sides. The top of the adjustment plate is fixedly connected to a limit seat, the two sides of the cable box are connected to push-pull rings, and the lower surface of the cable box is provided with a positioning groove.

[0015] Preferably, the lifting bracket mechanism includes a mobile power supply base, the rear surface of which is fixedly connected to the transmission traction slider, a supporting base plate fixedly connected to the lower end of the front surface of the mobile power supply base, a positioning guide pin fixedly connected to the upper surface of the supporting base plate, the positioning guide pin being inserted into the positioning groove, a blind-plug female seat embedded in the front surface of the mobile power supply base, and lateral pull pins provided on both sides of the mobile power supply base, the lateral pull pins being engaged with the push-pull ring.

[0016] Preferably, a fixing rod is fixedly connected inside the locking housing, and a sliding main shaft and a spring are sleeved on the fixing rod. One end of the sliding main shaft is fixedly connected to the push block.

[0017] Preferably, the adjustment plate has a magnet inside and a wear-resistant pad on its lower surface.

[0018] Preferably, a rubber block is provided at the opening behind the cable box corresponding to the cable routing groove, and a sealing sleeve is provided on the outside of the blind plug socket.

[0019] Preferably, mounting ear plates are fixedly connected to both sides of the main slide rail, a slide rail rear sealing plate is provided on the rear surface of the main slide rail, and a counterweight block is provided at the bottom of the main slide rail.

[0020] This invention also provides a sliding-track type convenient disassembly and assembly method for fixing a camera in a gate control room, comprising the following steps:

[0021] Step 1: Fit the mounting ear plate to the edge of the wall. Fill the gap between the main slide rail and the wall with the back sealing plate to fix it. Place the camera on the upper surface of the cable box. Arrange the connecting wires inside the cable tray. Pass the plug through the rear opening. Use the rubber block to hold and fix the cable. Slide the adjustment plate on the surface of the cable box to change the spacing of the limit seat to hold the camera base. Use the attraction provided by the magnet and the friction of the wear-resistant pad to complete the adjusted positioning.

[0022] Step 2: Place the cable box on the support base plate and position it so that the positioning guide pin is engaged in the positioning groove. The plug at the back of the cable box should be horizontally aligned with the blind plug female socket. Pull the push-pull rings on both sides to insert the plug into the blind plug female socket and seal it with the sealing sleeve. Then hang the push-pull rings on the surface of the side pull pins to completely fix and lock it.

[0023] Step 3: Turn the hand crank to drive the lower sprocket to rotate, and the transmission chain will be displaced, causing the transmission traction slider to slide upward in the central guide groove;

[0024] Step 4: When the transmission chain is displaced, the upper sprocket tooth pitch and the transmission chain links rotate synchronously. The teeth of the upper sprocket press against the swing plate. The swing plate rotates, causing the inclined plate to move and contact the stop block for limitation. When the swing plate is in the tooth gap, the push block is pushed by the spring force to cause the insert plate to disengage from the transmission chain. When the swing plate is pressed by the teeth, the inclined plate pushes the push block to slide inside the locking housing, causing the insert plate to insert into the gap of the transmission chain rollers for engagement. When the height adjustment is completed and rotation stops, the swing plate is in the state of being pressed by the teeth, and the insert plate remains engaged, completing the locking of the transmission chain after height adjustment.

[0025] This invention provides a sliding-track type convenient assembly and disassembly camera fixing device and method for opening and closing machine rooms. It has the following beneficial effects:

[0026] 1. This invention, through the cooperation of the lifting bracket mechanism and the hollow transfer mechanism, uses the positioning guide pin and positioning groove on the supporting base plate to complete the lateral limiting of the cable box. Pulling the push-pull ring backward allows the plug to slide straight into the blind-plug female socket. Then, the push-pull ring is hooked onto the surface of the lateral pull pin, which can realize the blind plug connection and mechanical locking of the power connector, and avoid the bending of the plug pins due to misalignment during operation.

[0027] 2. This invention, by setting up a high-altitude locking mechanism, utilizes the mechanical characteristics of the synchronous operation of the sprocket tooth pitch and the chain pitch. When the upper sprocket is running, the toothed edge squeezes the swing plate, causing the inclined plate to push the push block and drive the insert plate to move in and out of the gap of the chain rollers to avoid collisions. When the transmission chain stops rotating and the swing plate is under pressure, the insert plate remains deeply embedded in the chain link of the transmission chain. This can provide a rigid mechanical parking lock for the transmission components after adjustment, preventing the lifting bracket mechanism and equipment from falling due to their own weight.

[0028] 3. By setting up a chain transmission mechanism, the present invention uses a hand crank to drive the lower sprocket to rotate, causing the transmission chain to shift and pull the transmission traction slider in the central guide groove to slide up and down. This can convert the bottom rotation operation into a vertical lifting action, allowing the operator to adjust the height of the camera from the ground, reducing the safety risks of high-altitude maintenance operations.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a sliding track type convenient disassembly and assembly camera fixing device for a gate control room, comprising:

[0039] The main slide rail 1 is used for wall-mounted support of the overall device and for guiding the internal lifting mechanism. The main slide rail 1 provides wall-mounted support for the overall device, while the internal guide groove restricts the deflection of the internal components during the lifting process, ensuring that the camera 9 moves linearly and smoothly in the vertical direction.

[0040] The chain drive mechanism 5 is located inside the main slide rail 1 and is used to smoothly adjust the height of the internal slider by manual drive. The chain drive mechanism 5 converts the hand-cranked rotational motion at the ground into a vertical linear lifting motion through mechanical traction, so that the operator can adjust the height of the high-altitude camera 9 from the ground, avoiding the process of building scaffolding or using aerial work platforms for high-altitude operations.

[0041] The high-altitude locking mechanism 6 is located at the top of the main slide rail 1. It is used to lock the chain drive mechanism 5 after the height adjustment is completed to prevent it from falling due to gravity. The high-altitude locking mechanism 6 uses the mechanical teeth and the follow-up action of the insert plate 67 to hard lock the chain link when the drive chain 51 stops rotating. This is achieved by the reciprocating stroke of the spring 610 rebounding and the inclined plate 68 pressing, which prevents the lifting bracket mechanism 7 and the camera 9 from slipping and falling under their own weight.

[0042] The hollow adapter mechanism 8 is used to place and clamp and fix cameras 9 of different sizes, while hiding the connecting cable of the camera 9 inside. The hollow adapter mechanism 8 uses the adjustable characteristics of the spacing of the limit seat 86 to clamp cameras 9 of different sizes. At the same time, the cable tray 82 is used to store the excess tail cable of the camera 9, preventing the cable from being exposed to moisture in the outdoor environment for a long time or from being hooked and broken during the lifting operation.

[0043] The lifting bracket mechanism 7 is located between the chain drive mechanism 5 and the hollow transfer mechanism 8. It is used to support the hollow transfer mechanism 8 and cooperate to complete the blind plug connection and mechanical locking. The lifting bracket mechanism 7 uses the positioning guide pin 75 to limit the lateral displacement of the cable box 81, so that the cable box 81 can be pushed backward in a straight line, realizing the axial centering insertion of the power plug and the blind plug socket 73, avoiding plug misalignment or pin bending in the high-altitude environment.

[0044] Please see the appendix Figure 1 - Appendix Figure 3 In one embodiment of the present invention, mounting ear plates 2 are fixedly connected to both sides of the main slide rail 1, a slide rail rear sealing plate 3 is provided on the rear surface of the main slide rail 1, a counterweight block 54 is provided at the bottom of the main slide rail 1, a central guide groove 4 is provided on the inner wall of the main slide rail 1, the chain transmission mechanism 5 includes an upper sprocket 52 and a lower sprocket 53, a transmission chain 51 is connected between the upper sprocket 52 and the lower sprocket 53, a hand crank 55 is fixedly connected to the front surface of the lower sprocket 53, a transmission traction slider 56 is slidably connected inside the central guide groove 4, a fixing plate 57 is fixedly connected to the front surface of the transmission traction slider 56, and the rear surface of the fixing plate 57 is fixedly connected to the front surface of the transmission chain 51.

[0045] Specifically: During installation, fasteners are used to pass through the mounting ear plate 2 to connect the main slide rail 1 to the edge of the wall. The slide rail back sealing plate 3 fills the gap between the main slide rail 1 and the wall surface to increase the contact area and prevent the main slide rail 1 from tilting under load. When adjusting the height, turn the hand crank 55, and the lower sprocket 53 rotates inside the main slide rail 1 and drives the transmission chain 51 to run. The transmission chain 51 pulls the transmission traction slider 56 up and down in the central guide groove 4 through the fixing plate 57. The inner wall of the central guide groove 4 limits the two sides of the transmission traction slider 56 to prevent it from swaying back and forth or left and right during the lifting process. The counterweight block 54 at the bottom is used to increase the weight of the lower end of the main slide rail 1, lower the overall center of gravity, and reduce the vibration of the mechanism when driven by hand.

[0046] Please see the appendix Figure 1 - Appendix Figure 4 In one embodiment of the present invention, the high-altitude locking mechanism 6 includes a locking housing 61, a fixed rod 62 is fixedly connected inside the locking housing 61, a sliding main shaft 63 and a spring 610 are sleeved on the fixed rod 62, a push block 64 is fixedly connected to one end of the sliding main shaft 63, a stop block 66 is fixedly connected inside the locking housing 61, a swing plate 65 is movably connected to the locking housing 61 through a rotating shaft 69, an inclined plate 68 is fixedly connected to the bottom of the swing plate 65, the inclined plate 68 and the stop block 66 are in corresponding contact, the end of the swing plate 65 is engaged with the teeth of the upper sprocket 52 and pressed, one end of the push block 64 extends out of the locking housing 61 and is fixedly connected with an insert plate 67, the end of the insert plate 67 is correspondingly fitted into the link of the transmission chain 51;

[0047] Specifically: When the upper sprocket 52 rotates, the outer edge of the teeth of the upper sprocket 52 contacts the swing plate 65. Utilizing the synchronous characteristic of the tooth pitch of the upper sprocket 52 and the pitch of the transmission chain 51, when the tooth tip of the upper sprocket 52 abuts against the swing plate 65, the swing plate 65 deflects around the rotating shaft 69, causing the inclined plate 68 to press inward against the push block 64. The push block 64 overcomes the resistance of the spring 610, causing the insert plate 67 to slide forward into the gap between adjacent rollers of the transmission chain 51; when the swing plate 65 slides into... When there is a gap between the tooth tips of adjacent teeth of the upper sprocket 52, the squeezing force is lost, the spring 610 pushes the sliding main shaft 63 to drive the push block 64 to reset, and the insert plate 67 is pulled out from the link of the transmission chain 51; when the shaking stops and the tooth tip of the upper sprocket 52 stays at the position of the swing plate 65, the insert plate 67 remains embedded in the transmission chain 51, locking the transmission chain 51, and the stop block 66 is used to block the movement limit distance of the inclined plate 68 to prevent the insert plate 67 from bending and deforming due to excessive force.

[0048] Please see the appendix Figure 5 and attached Figure 7 In one embodiment of the present invention, the hollow transfer mechanism 8 includes a cable box 81, a cable routing groove 82 is provided inside the cable box 81, a rubber block 83 is provided at the opening corresponding to the cable routing groove 82 at the rear of the cable box 81, an adjustment plate 87 is slidably connected to both sides of the upper surface of the cable box 81, a magnet 85 is provided inside the adjustment plate 87, a wear-resistant pad 88 is provided on the lower surface of the adjustment plate 87, a limit seat 86 is fixedly connected to the top of the adjustment plate 87, push-pull rings 84 are connected to the outside of both sides of the cable box 81, and a positioning groove 89 is provided on the lower surface of the cable box 81.

[0049] Specifically: The base of the camera 9 is placed on the upper surface of the cable box 81, the connecting wire is embedded in the cable tray 82, the power plug extends from the opening at the rear of the cable box 81, and the rubber block 83 fills the opening. The pressure deformation of the rubber material squeezes and covers the connecting wire, preventing the cable from being pulled downward by gravity. The adjusting plates 87 on both sides are pushed to move laterally on the upper surface of the cable box 81, so that the two limiting seats 86 retract inward and press against the edge of the base of the camera 9. The magnet 85 attracts the metal parts inside the cable box 81, providing a vertical downward clamping force. The wear-resistant pad 88 increases the static friction of the sliding surface, keeping the adjusting plate 87 in a stationary position, thus completing the clamping and fixing of the camera 9.

[0050] Please see the appendix Figure 5 and attached Figure 6In one embodiment of the present invention, the lifting bracket mechanism 7 includes a mobile power supply base 71. The rear surface of the mobile power supply base 71 is fixedly connected to the transmission traction slider 56. The lower end of the front surface of the mobile power supply base 71 is fixedly connected to a support base plate 76. The upper surface of the support base plate 76 is fixedly connected to a positioning guide pin 75. The positioning guide pin 75 is inserted into the positioning groove 89. The front surface of the mobile power supply base 71 is provided with a blind insertion female seat 73. A sealing sleeve 74 is sleeved on the outside of the blind insertion female seat 73. Lateral pull pins 72 are provided on both sides of the mobile power supply base 71. The lateral pull pins 72 are engaged with the push-pull ring 84.

[0051] Specifically: The operator places the cable box 81 on the surface of the support base plate 76, inserts the positioning guide pin 75 into the positioning groove 89, and restricts the cable box 81 from sliding left and right along the surface of the support base plate 76. At this time, the plug terminal exposed at the rear end of the cable box 81 is on the same horizontal axis as the socket of the blind-plug female socket 73. Pulling the push-pull ring 84 backward, the cable box 81 slides straight backward along the positioning guide pin 75, and the plug is directly inserted into the blind-plug female socket 73 to conduct power. After the connection is completed, the rear side wall of the cable box 81 squeezes the sealing sleeve 74, so that the sealing sleeve 74 is tightly attached to the outer periphery of the mating surface, preventing external rainwater from entering the conductive pin part. Then, the push-pull ring 84 is sleeved on the outer surface of the lateral pull pin 72. The structural interference after the push-pull ring 84 is attached prevents the cable box 81 from sliding forward and backward, keeping the connection between the plug and the blind-plug female socket 73 from falling off.

[0052] This invention also provides a method for using a sliding track-type convenient disassembly and assembly camera fixing device for the gate control room, comprising the following steps:

[0053] Step 1: Fit the mounting ear plate 2 to the edge of the wall, fill the gap between the main slide rail 1 and the wall with the slide rail back sealing plate 3 to complete the fixation, place the camera 9 on the upper surface of the cable box 81, arrange the connecting wires inside the cable tray 82, and pass the plug through the rear opening. Use the rubber block 83 to clamp and fix the cable. Inside the cable box 81, slide the adjustment plate 87 to change the spacing of the limit seat 86 to clamp the camera 9. The adjusted position is fixed by the attraction of the magnet 85 and the wear-resistant pad 88.

[0054] Step 2: Place the cable box 81 on the support base plate 76, so that the positioning guide pin 75 is inserted into the positioning groove 89 to complete the lateral limit. The plug at the rear of the cable box 81 is horizontally aligned with the blind plug female socket 73. Pull the push-pull rings 84 on both sides backward to push the plug into the blind plug female socket 73 and seal it with the pressure of the sealing sleeve 74. Then, hang the push-pull rings 84 on the surface of the lateral pull pin 72 to restrict the cable box 81 from moving forward.

[0055] Step 3: Turn the hand crank 55 to drive the lower sprocket 53 to rotate, and the transmission chain 51 will be displaced, causing the transmission traction slider 56 to slide upward in the central guide groove 4;

[0056] Step 4: When the transmission chain 51 is displaced, taking advantage of the synchronous operation of the tooth pitch of the upper sprocket 52 and the links of the transmission chain 51, the teeth of the upper sprocket 52 press against the swing plate 65. The swing plate 65 rotates, causing the inclined plate 68 to move and contact the stop block 66 for limitation. When the swing plate 65 is located in the gap of the teeth of the upper sprocket 52, the push block 64 is pushed by the spring 610 to drive the insert plate 67 to disengage from the transmission chain 51. When the swing plate 65 is pressed by the tooth tip of the upper sprocket 52, the inclined plate 68 pushes the push block 64 to slide inside the locking housing 61, causing the insert plate 67 to be inserted into the gap of the rollers of the transmission chain 51 for engagement. When the height adjustment is completed and rotation stops, the swing plate 65 is in the state of being pressed by the tooth tip, and the insert plate 67 remains engaged with the transmission chain 51 to complete the locking.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended description and its equivalents.

10. A method for fixing a camera in a sliding-track type convenient disassembly and assembly opening / closing machine room, characterized in that, Using the sliding-type convenient disassembly and assembly camera fixing device for the gate control room as described in any one of claims 1-9 includes the following steps: Step 1: Fit the mounting ear plate (2) to the edge of the wall, fill the gap between the main slide rail (1) and the wall with the slide rail back sealing plate (3) to complete the fixation, place the camera (9) on the upper surface of the cable box (81), arrange the connecting wires inside the cable tray (82), and pass the plug through the rear opening. Use the rubber block (83) to clamp and fix the cable. Slide the adjustment plate (87) on the surface of the cable box (81) to change the spacing of the limit seat (86) to clamp the base of the camera (9). Use the attraction provided by the magnet (85) and the friction of the wear-resistant pad (88) to complete the position fixation. Step 2: Place the cable box (81) on the support base plate (76) and position it so that the positioning guide pin (75) is inserted into the positioning groove (89). The plug at the back of the cable box (81) is horizontally aligned with the blind plug female socket (73). Pull the push-pull rings (84) on both sides backward to insert the plug into the blind plug female socket (73) and seal it with the sealing sleeve (74). Then hang the push-pull rings (84) on the surface of the side pull pin (72) for complete fixation and locking. Step 3: Turn the hand crank (55) to drive the lower sprocket (53) to rotate, and the transmission chain (51) will be displaced, causing the transmission traction slider (56) to slide upward in the central guide groove (4); Step 4: When the transmission chain (51) is displaced, the tooth pitch of the upper sprocket (52) and the link of the transmission chain (51) are synchronously rotated. The tooth of the upper sprocket (52) presses against the swing plate (65). The swing plate (65) rotates and drives the inclined plate (68) to move and contact the stop block (66) for limitation. When the swing plate (65) is located in the tooth gap, the push block (64) is pushed by the spring (610) to drive the insert plate (67) to disengage from the transmission chain (51). When the swing plate (65) is pressed by the tooth, the inclined plate (68) pushes the push block (64) to slide inside the locking housing (61), driving the insert plate (67) to insert into the roller gap of the transmission chain (51) for engagement. When the height adjustment is completed and the rotation stops, the swing plate (65) is in the state of being pressed by the tooth top, and the insert plate (67) remains engaged with the transmission chain (51) to complete the locking.
