Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically to an inspection device based on guide rail technology. Background Technology
[0002] This fire inspection device, based on guide rail technology, is specifically designed for building fire safety monitoring. It constructs a full-coverage inspection channel using modular guide rail components (wall-mounted / ceiling-mounted). Equipped with a high-definition camera, temperature and humidity sensors, smoke detectors, and gas detection modules, the device moves precisely along pre-set guide rails to achieve 24-hour automated inspection of key building areas (evacuation routes, equipment rooms, storage areas, etc.). Its core advantage lies in the stable movement guided by the guide rails, overcoming blind spots in manual inspections and adapting to complex scenarios such as high-rise buildings and large factories. It collects environmental data in real time and synchronizes it to the fire monitoring platform. Abnormal situations (overheating, smoke, gas leaks) immediately trigger audible and visual alarms and location tracking, linking with the emergency response system for rapid response. This device significantly improves inspection efficiency and accuracy, reduces manual maintenance costs, and builds a robust intelligent protection barrier for fire safety.
[0003] In existing technologies, the stable movement characteristics of guide rails can achieve full coverage and no blind spots in key fire protection areas of buildings, effectively breaking through the height limitations and blind spots of manual inspections. They are suitable for complex scenarios such as high-rise buildings, large factories, and warehouses. However, most of them use a single guide rail for guidance and movement, which has poor load-bearing capacity and stability. Moreover, they do not have a braking component, which makes it difficult for the device to brake quickly as a whole. Their practicality is poor and they are not easy to promote and use. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an inspection device based on guide rail technology. It can effectively solve the problems in the existing technology, which mostly uses a single guide rail for guiding movement, has poor load-bearing capacity and stability, and does not have a brake component, making it difficult for the whole device to brake quickly, resulting in poor practicality and difficulty in promotion and use.
[0005] The technical solution adopted by this utility model is: an inspection device based on guide rail technology, including a first guide rail, a second guide rail and a housing. The inner wall of the housing is fixedly installed with a first fixing rod and a second fixing rod. The outer wall of the first guide rail is fixedly provided with a pulley assembly and a drive assembly. The outer wall of the second guide rail is provided with a pulley assembly and a drive assembly. The inner wall of the housing is fixedly installed with a first mounting bracket. The outer wall of the first mounting bracket is fixedly installed with a dual-axis motor. The end of the housing near the first guide rail is fixedly installed with a second mounting bracket. The end of the second mounting bracket away from the housing is provided with a brake assembly. The end of the housing away from the first guide rail is fixedly installed with a camera pan-tilt unit.
[0006] Preferably, the pulley assembly one and the fixing rod one are fixedly installed, and the pulley assembly two and the fixing rod two are fixedly installed.
[0007] Through the above technical solution, the design of pulley assembly one and pulley assembly two serves as the core load-bearing components for the overall movement along the guide rail. In scenarios where the inspection device reciprocates along the guide rail for a long time, the fixed connection can effectively disperse the vibration and impact force generated during the movement, preventing problems such as operation jamming and deviation caused by loose connection.
[0008] Preferably, both pulley assembly one and pulley assembly two are provided in two identical units, with the two pulley assemblies one being symmetrically distributed about the center line of the fixed rod one, and the two pulley assemblies two being symmetrically distributed about the center line of the fixed rod two.
[0009] The above technical solution, through the design of two pulley assemblies, further improves the overall load-bearing capacity, prevents the device from swaying or tilting when moving along the guide rail, ensures that the camera pan-tilt unit and other detection components always maintain a stable shooting angle, and improves the accuracy of inspection data.
[0010] Preferably, both drive component one and drive component two are driven by a dual-axis motor.
[0011] The above technical solution, through the design of a dual-axis motor, can simultaneously provide power to both drive component one and drive component two, avoiding the power imbalance problem caused by differences in motor parameters when using two independent motors. This prevents "dragging" or "deviation" when the device moves along the dual guide rails, ensuring smooth operation on both straight and curved guide rails. It also reduces the manufacturing cost and weight of the device, decreases potential failure points, and facilitates later maintenance and repair. Preferably, the brake assembly includes an electric telescopic cylinder, with a connecting rod rotatably mounted on the output end of the electric telescopic cylinder. A fixed seat is fixedly mounted on the outer wall of the second mounting bracket, and a rotating shaft is rotatably mounted on the outer wall of the fixed seat. A third mounting bracket is fixedly mounted on the outer wall of the rotating shaft. A positioning groove and a threaded hole are fixedly installed on the outer wall of the third mounting bracket. A bolt is threadedly connected to the outer wall of the third mounting bracket. A mounting plate is provided at the end of the third mounting bracket away from the rotating shaft. A positioning block is fixedly mounted on the side of the mounting plate near the third mounting bracket. A threaded hole is provided on the side of the mounting plate near the third mounting bracket. A brake block is fixedly mounted on the side of the mounting plate away from the third mounting bracket. A protrusion is fixedly mounted on the side of the brake block away from the mounting plate. The connecting rod and the rotating shaft are fixedly mounted. Two identical brake blocks are provided, one brake block located inside the first guide rail and the other brake block located inside the second guide rail.
[0012] With the above technical solution, the staff activates the electric telescopic cylinder, the output end of the electric telescopic cylinder extends, and through the cooperation of the connecting rod and the rotating shaft, the rotating shaft drives the rotating shaft to rotate. The rotation of the rotating shaft drives the mounting frame to rotate, and the rotation of the mounting frame drives the brake block to rotate, so that the brake block abuts against the first guide rail and the second guide rail, forming a double guide rail synchronous braking, which greatly improves the braking effect and avoids the device tilting or sliding caused by single guide rail braking. It is especially suitable for inspection scenarios at high altitudes or with tilted guide rails, ensuring the safety of equipment and the site.
[0013] Preferably, the bumps are provided in multiple identical manner, and the multiple bumps are distributed at equal intervals.
[0014] The above technical solution, through the design of multiple protrusions, increases the contact area between the brake block and the first and second guide rails, thereby further improving the braking performance of the brake assembly.
[0015] Preferably, the positioning block and the positioning groove are installed by plugging in, and the bolt extends through the first threaded hole to the inside of the second threaded hole, wherein the first threaded hole and the second threaded hole have the same diameter.
[0016] Using the above technical solution, the staff inserts the positioning block into the positioning groove, and then inserts the bolt through the threaded hole one to the threaded hole two, which can realize the quick installation of the brake block and facilitate its replacement after long-term use.
[0017] Compared with the prior art, this utility model provides an inspection device based on guide rail technology, which has the following advantages: 1. This inspection device based on guide rail technology, through the design of the brake assembly, can form synchronous braking of dual guide rails, which greatly improves the braking effect and avoids the device tilting or sliding caused by single guide rail braking. It is especially suitable for inspection scenarios with high altitude or inclined guide rails, ensuring the safety of equipment and site. Through the design of multiple protrusions, the contact area between the brake block and the first and second guide rails is increased, further improving the braking performance of the brake assembly. Through the cooperation of the positioning block and positioning groove and bolts, and threaded hole one and threaded hole two, the brake block can be quickly installed and is easy to replace after long-term use. 2. This inspection device based on guide rail technology uses pulley assembly one and pulley assembly two as the core load-bearing components for the overall movement along the guide rail. In scenarios where the inspection device moves back and forth along the guide rail for a long time, the fixed connection can effectively disperse the vibration and impact force generated during the movement, preventing problems such as operation jamming and deviation caused by loose connection. The design of pulley assembly one and pulley assembly two further improves the overall load-bearing capacity, preventing the device from swaying or tilting when moving along the guide rail, ensuring that the detection components such as the camera pan-tilt unit always maintain a stable shooting angle, and improving the accuracy of inspection data. The design of dual-axis motors can provide power to drive assembly one and drive assembly two at the same time, avoiding the power imbalance problem caused by the difference in motor parameters when using two independent motors, preventing "dragging" or "deviation" when the device moves along the dual guide rails, ensuring that the device can operate smoothly on straight or curved guide rails, while reducing the manufacturing cost and weight of the device, reducing the number of failure points, and facilitating later maintenance and repair.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: As Figure 1-6 As shown, the present invention provides an inspection device based on guide rail technology, comprising a first guide rail 1, a second guide rail 14, and a housing 2. A first fixing rod 3 and a second fixing rod 4 are fixedly installed on the inner wall of the housing 2. A first pulley assembly 5 and a first drive assembly 7 are fixedly installed on the outer wall of the first guide rail 1. A second pulley assembly 6 and a second drive assembly 8 are installed on the outer wall of the second guide rail 14. A first mounting bracket 9 is fixedly installed on the inner wall of the housing 2. A dual-axis motor 10 is fixedly installed on the outer wall of the first mounting bracket 9. A second mounting bracket 11 is fixedly installed at the end of the housing 2 closest to the first guide rail 1. A brake assembly 12 is provided at the end of the second mounting bracket 11 furthest from the housing 2. A camera pan-tilt unit 13 is fixedly installed at the end of the housing 2 furthest from the first guide rail 1.
[0022] Specifically, pulley assembly 5 and fixed rod 3 are fixedly installed, and pulley assembly 6 and fixed rod 4 are fixedly installed. The advantage is that, through the design of pulley assembly 5 and pulley assembly 6, they serve as the core load-bearing components for the overall movement along the guide rail. In scenarios where the inspection device reciprocates along the guide rail for extended periods, the fixed connection effectively disperses the vibration and impact forces generated during movement, preventing problems such as operational jamming and misalignment caused by loose connections.
[0023] Specifically, both pulley assembly 5 and pulley assembly 6 have two identical components. The two pulley assemblies 5 are symmetrically distributed about the center line of the fixing rod 3, and the two pulley assemblies 6 are symmetrically distributed about the center line of the fixing rod 4. The advantage is that the design of the two pulley assemblies 5 and 6 further improves the overall load-bearing capacity, prevents the device from swaying or tilting when moving along the guide rail, ensures that the camera pan-tilt unit 13 and other detection components maintain a stable shooting angle, and improves the accuracy of inspection data.
[0024] Specifically, both drive assembly 7 and drive assembly 8 are driven by a dual-axis motor 10. The advantage is that the dual-axis motor 10 design can simultaneously power both drive assembly 7 and drive assembly 8, avoiding the power imbalance caused by differences in motor parameters when using two independent motors. This prevents "dragging" or "deviation" when the device moves along the dual guide rails, ensuring smooth operation on both straight and curved guide rails. It also reduces manufacturing costs and weight, decreases potential failure points, and facilitates later maintenance and repair. Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.
[0025] Specifically, the brake assembly 12 includes an electric telescopic cylinder 1201. A connecting rod 1202 is rotatably mounted on the output end of the electric telescopic cylinder 1201. A fixed seat 1203 is fixedly mounted on the outer wall of the mounting bracket 11. A rotating shaft 1204 is rotatably mounted on the outer wall of the fixed seat 1203. A mounting bracket 1205 is fixedly mounted on the outer wall of the rotating shaft 1204. A positioning groove 1206 and a threaded hole 1207 are fixedly mounted on the outer wall of the mounting bracket 1205. Bolts 1208 are threadedly connected to the outer wall of the mounting bracket 1205. A mounting plate 1209 is provided at the end of the mounting bracket 1205 away from the rotating shaft 1204. A positioning block 1210 is fixedly installed on the side of the mounting plate 1209 near the mounting bracket 1205. A threaded hole 1211 is opened on the side of the mounting plate 1209 near the mounting bracket 1205. A brake block 1212 is fixedly installed on the side of the mounting plate 1209 away from the mounting bracket 1205. A protrusion 1213 is fixedly installed on the side of the brake block 1212 away from the mounting plate 1209. The connecting rod 1202 and the rotating shaft 1204 are fixedly installed. Two identical brake blocks 1212 are provided. One brake block 1212 is located inside the first guide rail 1, and the other brake block 1212 is located inside the second guide rail 14. The advantage is that when the operator starts the electric telescopic cylinder 1201, the output end of the electric telescopic cylinder 1201 extends, and through the cooperation of the connecting rod 1202 and the rotating shaft 1204, the rotating shaft 1204 is driven to rotate. The rotation of the rotating shaft 1204 drives the mounting bracket 1205 to rotate, and the rotation of the mounting bracket 1205 drives the brake block 1212 to rotate, so that the brake block 1212 abuts against the first guide rail 1 and the second guide rail 14, forming a double guide rail synchronous braking, which greatly improves the braking effect and avoids the device tilting or sliding caused by single guide rail braking. It is especially suitable for inspection scenarios at high altitudes or with tilted guide rails, ensuring the safety of equipment and the site.
[0026] Specifically, multiple identical protrusions 1213 are provided, and the multiple protrusions 1213 are distributed at equal intervals. The advantage is that by designing multiple protrusions 1213, the contact area between the brake block 1212 and the first guide rail 1 and the second guide rail 14 is increased, further improving the braking performance of the brake assembly 12.
[0027] Specifically, the positioning block 1210 and the positioning groove 1206 are installed by insertion. The bolt 1208 extends through the first threaded hole 1207 and into the second threaded hole 1211. The diameters of the first threaded hole 1207 and the second threaded hole 1211 are the same. The advantage is that the operator can quickly install the brake block 1212 by inserting the positioning block 1210 into the positioning groove 1206 and then extending the bolt 1208 through the first threaded hole 1207 into the second threaded hole 1211. After long-term use, it is easy to replace.
[0028] Working Principle: During installation, the operator inserts the positioning block 1210 into the positioning slot 1206, and then extends the bolt 1208 through the threaded hole 1207 to the threaded hole 1211, enabling quick installation of the brake block 1212. This facilitates replacement after prolonged use. During operation, the pulley assembly 5 and pulley assembly 6 form the core load-bearing components for the overall movement along the guide rail. In scenarios where the inspection device reciprocates along the guide rail for extended periods, the fixed connection effectively disperses vibrations and impacts generated during movement, preventing issues such as jamming or offset due to loose connections. The design of the two pulley assemblies 5 and 6 further enhances the overall load-bearing capacity, preventing lateral swaying or tilting of the device while moving along the guide rail, ensuring that the camera pan-tilt unit 13 and other detection components maintain a stable shooting angle, thus improving the accuracy of inspection data. The dual-axis motor 10 provides power to both drive assembly 7 and drive assembly 8 simultaneously, avoiding the performance issues caused by differences in motor parameters when using two independent motors. To address force imbalance issues and prevent "dragging" or "deviation" during the device's movement along the dual guide rails, ensuring smooth operation on both straight and curved guide rails, the device's manufacturing cost and weight are reduced. This also minimizes potential failure points and facilitates later maintenance and repair. When the entire device is moved to the appropriate position, the operator activates the electric telescopic cylinder 1201. The output end of the electric telescopic cylinder 1201 extends, driving the rotating shaft 1204 through the cooperation of the connecting rod 1202 and the rotating shaft 1204. The rotation of the rotating shaft 1204 then drives the mounting bracket 120... 5. Rotation of the mounting bracket 1205 causes the brake block 1212 to rotate, making the brake block 1212 contact the first guide rail 1 and the second guide rail 14, forming a double guide rail synchronous braking, which greatly improves the braking effect and avoids the device tilting or sliding caused by single guide rail braking. It is especially suitable for inspection scenarios at high altitudes or with tilted guide rails, ensuring the safety of equipment and the site. Through the design of multiple protrusions 1213, the contact area between the brake block 1212 and the first guide rail 1 and the second guide rail 14 is increased, further improving the braking performance of the brake assembly 12.
[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
