Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment support technology, specifically to a telescopic adjustable pan-tilt frame for monitoring blasting sites. Background Technology

[0002] In blasting operations such as mining and tunnel construction, monitoring equipment is typically installed at the blasting site to record the entire process, ensuring operational safety, assessing blasting effectiveness, and conducting subsequent accident analysis. This monitoring equipment usually needs to be mounted on a dedicated pan-tilt mount for stable support.

[0003] Due to the complex and varied terrain at blasting sites, and the need to mount monitoring equipment at different heights or distances to obtain the best monitoring perspective, a pan-tilt mount with telescopic functionality, capable of easily adjusting its height or length, is crucial for on-site deployment.

[0004] In the process of realizing this utility model, the inventors discovered that: Existing pan-tilt units with multi-angle adjustment lack precision. Mechanical transmission gaps and hand tremors make it difficult to accurately align with the target, resulting in easily shifted and blurred images. Operation in special locations is inconvenient, and debugging in high-altitude or remote areas requires climbing or traveling back and forth, posing safety hazards and low efficiency. Manual operation can easily accumulate angle errors, and multiple units working together can easily create monitoring blind spots, increasing maintenance workload. Operators also experience high physical and mental exertion, making it difficult to adapt to scenarios that require frequent switching of viewing angles, resulting in poor adaptability. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model provides a telescopic adjustable gimbal for monitoring blasting sites, which has the characteristics of convenient operation.

[0006] Therefore, the technical solution of this utility model is as follows: a telescopic adjustable gimbal frame for monitoring blasting sites, including a gimbal support base and a support telescopic assembly disposed above the gimbal support base. The support telescopic assembly includes a fixed support and an extension support rotatably inserted inside the fixed support. The feature is that it also includes a direction adjustment mechanism, which includes a flexible swing block. The bottom of the flexible swing block is rotatably connected to the free end of the flexible swing arm and the arm end of the U-shaped swing arm at different positions, and is driven by a motor.

[0007] Preferably, the direction adjustment mechanism further includes a gimbal mounting base plate, which is fixedly connected to the top of the flexible swing block, serving as the final support platform for the monitoring gimbal, and swings synchronously with the flexible swing block to achieve viewing angle adjustment.

[0008] Preferably, the direction adjustment mechanism includes a support plate, which is fixedly connected to the end of the extension bracket away from the gimbal bracket base, serving as the mounting platform for the entire direction adjustment mechanism.

[0009] Preferably, the direction adjustment mechanism further includes motor one and motor two, which are fixedly mounted side by side on the support plate as a power source for realizing the direction adjustment of the gimbal.

[0010] Preferably, the direction adjustment mechanism further includes a swing arm 1 and a flexible swing arm 2 that are connected to the motor 1. One end of the swing arm 1 is rotatably connected to the output shaft of the motor 1, and the other end is rotatably connected to the flexible swing arm 2, forming a first set of transmission links.

[0011] Preferably, the direction adjustment mechanism further includes a U-shaped swing arm that is connected to the second motor. The middle part of the U-shaped swing arm is rotatably connected to the output shaft of the second motor, forming a second set of transmission links. The flexible swing block serves as a motion convergence point, receiving and integrating the motion from the two sets of transmission links.

[0012] Preferably, the fixed bracket has a guide groove on its support wall, and the extension bracket has a guide pin fixed on its support wall. The guide pin is slidably disposed in the guide groove. When the extension bracket rotates around its own axis, the extension bracket is driven to extend or retract along the axis of the fixed bracket through the cooperation of the guide pin and the guide groove. The fixed bracket is covered with a protective cover to prevent dust from entering and causing jamming or difficulty in operation.

[0013] Preferably, the support telescopic assembly also includes a protective sleeve, which is arranged in a ring and respectively attached to the port of the fixed support and the outer wall of the extension support, for sealing and protecting the connection between the fixed support and the extension support, and can effectively prevent external dust, moisture and other impurities from entering.

[0014] Beneficial Effects: This utility model solves the problem of existing technologies being unable to safely, remotely, and precisely adjust the monitoring angle in dangerous environments such as blasting sites by using a dual-motor driven linkage mechanism to control the attitude of the pan-tilt mounting base. This achieves the technical effects of remote control, rich adjustment dimensions, and precise positioning. By using a guide groove on the fixed bracket and a guide pin on the extension bracket in sliding engagement, the rotational motion of the extension bracket is converted into smooth axial telescopic motion. This solves the problems of complex, easily jammed, and unstable height adjustment processes in existing technologies, achieving convenient telescopic adjustment operation, a smooth process, and precise positioning. By adding a protective sleeve and cover at the connection between the fixed bracket and the extension bracket for sealing, the problem of existing telescopic structures being easily invaded by dust and moisture from blasting sites, leading to jamming or wear, is solved. This effectively protects the internal transmission structure and improves the overall durability and environmental adaptability of the device. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0021] This utility model is as follows Figures 1 to 4 As shown: A telescopic adjustable pan-tilt unit for monitoring blasting sites is proposed, which aims to solve the problems of inconvenient operation of the telescopic structure when adjusting the height of existing monitoring pan-tilt units used at blasting sites, and the instability caused by dust pollution.

[0022] Figure 1 As shown, it includes a pan-tilt bracket base 1 and a bracket telescopic assembly 2 fixedly connected to the top of the pan-tilt bracket base 1; the pan-tilt bracket base 1 is used to securely install the entire device on the working plane, and the bracket telescopic assembly 2 is used to realize the axial adjustment of the installation height of the monitoring equipment. Specifically, refer to Figure 2 The support telescopic assembly 2 includes a fixed support 21 and an extension support 23. The extension support 23 is rotatably inserted into the fixed support 21, and the telescopic function is achieved by rotating the extension support 23. In order to convert the rotational motion into a smooth linear telescopic motion, the core structure of the support telescopic assembly 2 is as follows: Figure 3The extension bracket 23 has an outwardly extending guide pin 22 fixed on its bracket wall. Correspondingly, the fixed bracket 21 has a guide groove 25 that cooperates with the guide pin 22 on its bracket wall. In the assembled state, the guide pin 22 is slidably disposed in the guide groove 25. When the bracket height needs to be adjusted, the extension bracket 23 is rotated. While the extension bracket 23 rotates around its own axis, the guide pin 22 on it slides along the trajectory of the guide groove 25 on the fixed bracket 21. This pin-groove cooperation structure smoothly converts the rotational motion of the extension bracket 23 into its extension or retraction motion along the axial direction of the fixed bracket 21, thereby realizing the adjustment of the overall height of the monitoring pan-tilt unit. At the same time, limit grooves are also provided at different height positions of the guide groove to prevent the extension bracket from retracting under the action of gravity.

[0023] Reference Figure 2 A protective sleeve 24 is also provided at the connection between the fixed bracket 21 and the extension bracket 23. The protective sleeve 24 is ring-shaped and fits between the outer edge of the port of the fixed bracket 21 and the outer wall of the extension bracket 23. It is used to seal the expansion and contraction gap between the fixed bracket 21 and the extension bracket 23. At the same time, a protective cover 4 is provided on the outside of the fixed bracket 21 to prevent dust, water vapor or debris from the blasting site from entering the guide groove 25, thereby ensuring smooth and reliable expansion and contraction adjustment. It should be noted that when the extension bracket 23 moves relative to the fixed bracket 21, it is above the fixed bracket 21. Therefore, the protective cover 4 will not interfere with the movement of the extension bracket 23. Figure 1 and Figure 4 In the process, the gimbal frame also includes a direction adjustment mechanism 3, which is integrally installed on the end of the extension bracket 23 away from the gimbal frame base 1. The direction adjustment mechanism 3 includes a support plate 31 as its mounting base, which is fixedly connected to the top of the extension bracket 23. The power source of the direction adjustment mechanism 3 is provided by motor 1 32 and motor 2 35, which are fixedly installed side by side on the top surface of the support plate 31. The transmission part of the direction adjustment mechanism 3 consists of a linkage mechanism, including a swing arm 1 33 and a flexible swing arm 2 34 that are connected to motor 1 32, and a U-shaped swing arm 36 that is connected to motor 2 35. The specific connection relationship is as follows: one end of the swing arm 33 is rotatably connected to the output shaft of the motor 32, and the other end of the swing arm 33 is rotatably connected to the flexible swing arm 34; the middle part of the U-shaped swing arm 36 is rotatably connected to the output shaft of the motor 35. The direction adjustment mechanism 3 also includes a flexible swing block 37 as a motion hub. The bottom of the flexible swing block 37 is rotatably connected to the free end of the flexible swing arm 34 and the arm end of the U-shaped swing arm 36 at different positions, so that the flexible swing block 37 can receive the combined drive from the motor 1 32 and the motor 2 35 and generate complex compound swing motion. The direction adjustment mechanism 3 also includes a pan-tilt mounting base plate 38 for mounting the monitoring equipment. The pan-tilt mounting base plate 38 is fixedly connected to the top of the flexible swing block 37. The pan-tilt mounting base plate 38 swings synchronously with the movement of the flexible swing block 37, thereby realizing remote and precise control of the shooting angle of the monitoring equipment.

[0024] The working principle of this utility model: When adjusting the height, the extension bracket 23 is rotated by external force. As the extension bracket 23 rotates around its own axis, the guide pin 22 fixed on its bracket wall slides along the guide groove 25 on the bracket wall of the fixed bracket 21. This pin-groove transmission structure smoothly converts the rotational motion of the extension bracket 23 into axial linear motion, thereby enabling the extension bracket 23 to extend or retract relative to the fixed bracket 21 to adjust the overall installation height of the monitoring equipment. This solves the problem of inconvenience in manual adjustment. At the same time, the protective sleeve 24 and the protective cover 4 seal the telescopic structure to prevent on-site pollutants from interfering with it.

[0025] When adjusting the monitoring direction, the external control system starts motor 32 or motor 35. When motor 32 is working, its output shaft drives swing arm 33 to swing. Swing arm 33 then transmits the motion to flexible swing block 37 through flexible swing arm 34, which is rotatably connected to it. When motor 35 is working, its output shaft drives U-shaped swing arm 36 to swing. U-shaped swing arm 36 also transmits the motion to flexible swing block 37. Through the coordinated or individual work of motors 32 and 35, the entire linkage mechanism is driven to move, ultimately causing flexible swing block 37 to produce a preset swing posture. The gimbal mounting base plate 38 fixed on the top of flexible swing block 37 swings synchronously, thereby driving the monitoring gimbal mounted on it to achieve multi-dimensional direction adjustment, meeting the needs of remote safety monitoring at the blasting site.

[0026] Any aspects not described in detail in this specification are techniques well-known in the art.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
