Description

Pipeline inspection auxiliary hoisting engineering vehicle Technical Field

[0001] This invention relates to the field of auxiliary testing equipment technology, and in particular to a pipeline testing auxiliary hoisting vehicle. Background Technology

[0002] The pipeline inspection robot, also known as the CCTV inspection robot, consists of four parts: a camera, a crawler, a control system, and a cable reel. It utilizes wireless transmission technology for connection, and an intelligent terminal controls the robot and cable cart for intelligent automatic cable reeling and unloading. Its modular design ensures each part of the machine is independently waterproof. The equipment can perform endoscopic inspections of pipes with diameters from DN200 to 3000 mm, and features four key characteristics: high-definition and high-brightness display, lightweight and efficient operation, digital transmission, and stable performance. The inspection equipment has specific requirements regarding the water flow, pipe diameter, and operating speed within the pipeline. The camera captures clear and accurate images, ensuring proper recording of data and distance from the pipeline.

[0003] Traditionally, CCTV inspection robots need to be placed at pipe openings. Some pipes are located in manholes, requiring manual entry. However, due to the depth of the manholes and the toxic gases produced during pipe use, the traditional method of manual entry can easily lead to poisoning of personnel. Furthermore, manual adjustments are required during equipment operation, resulting in significant waste of human and financial resources and creating unnecessary safety hazards. Summary of the Invention

[0009] Furthermore, the transmission rod of the transmission assembly has a long shaft structure. The transmission rod is rotatably mounted on the upper end of the rotating ring. The transmission rod is configured as two sets, one in front and one behind. Both ends of the transmission rod are provided with external connectors, which are hexagonal prism structures. A synchronous shaft is installed on the left side between the two sets of transmission rods. The synchronous shaft is connected to both sets of transmission rods simultaneously through bevel gears.

[0010] Furthermore, the driven assembly's reel drum is configured to be sleeved and mounted on the shaft of the transmission rod. The inner wall of the reel drum is provided with a protrusion, and the shaft wall of the transmission rod is provided with a groove corresponding to the protrusion on the inner wall of the reel drum. Two sets of reel drums are installed on the transmission rod at the same time. A fixing block is provided in the middle position of the transmission rod, and leaf springs are provided at both ends of the fixing block. The fixing block is located in the middle of the transmission rod.

[0011] Furthermore, rotating frames are rotatably mounted on the outer sides of both ends of the reel drum, and sliding frames are added between the rotating frames. The sliding frames are provided with sliding grooves, and guide buckles are slidably installed in the sliding grooves of the sliding frames. The guide buckles are provided with holes, and steel ropes are inserted through the holes of the guide buckles.

[0012] Furthermore, the walking platform of the bearing component is provided with protruding heads at the front and rear edges, and guide cylinders are snapped onto the protruding heads of the walking platform. Steel ropes are embedded and fixed inside the guide cylinders. The upper end face of the walking platform is set as an arc-shaped structure, and protruding strips are provided at the arc-shaped structure position of the walking platform.

[0013] Furthermore, the top of the control handle is sleeve-shaped, the inner wall of the sleeve is hexagonal, the outer end of the sleeve has an annular groove, and the outer wall of the sleeve has gear teeth. Beneficial Effects

[0014] I. This invention pushes the frame assembly to the designated position of the pipe well via the bottom wheels and handle frame. The self-locking bottom wheels provide stable positioning. The auxiliary component fixed to the lower end of the rotating component on the frame assembly carries the testing instruments and cable winch. The guide wheels on the auxiliary component and the guide wheels on the carrying component both assist in guiding the cables. The carrying component is used to carry the testing vehicle and is controlled by the driven component and the transmission component. All components controlling and lifting the carrying component are installed on the rotating component, allowing the rotating component to better correspond to any angle of the opening at the lower end of the pipe well, thus facilitating the entry of the testing vehicle on the carrying component.

[0015] Second, the present invention installs bottom wheels at the bottom positions of the four corners of the support frame, so that the support frame with bottom wheels can be moved easily. At the same time, the bottom wheels are designed with a locking structure to facilitate fixing the entire frame assembly in a designated position. Since the handlebar frame is installed in a hinged manner, in order to avoid the end bracket of the handlebar frame from contacting the rotating components and other components when the handlebar frame is closed, the end of the handlebar frame is directly set to be inclined, thus avoiding damage to the rotating components and other components by the end of the handlebar frame.

[0016] Third, the present invention provides a horizontal support plate at the support column, which serves as a support instrument for the auxiliary components to be tested for load-bearing capacity inside the vehicle frame assembly. The support plate is also equipped with a winch for cables, so the guide wheel set at the support plate guides the cables of the winch. The guide wheel installed on the support assembly also guides the cables for detecting the position of the vehicle body.

[0017] Fourth, in this invention, a control handle is fitted onto the shaft of the mounting bracket. The control handle presses the positioning block on the shaft of the mounting bracket inward, causing the positioning block to disengage from the rotating ring. When the control handle is rotated, it can drive the rotating ring, thereby adjusting the rotation of the rotating component. Similarly, after the control handle is removed, the positioning block rests against the inner wall of the rotating ring again, thus achieving the circumferential rotation fixation of the rotating component as a whole.

[0018] Fifth, the control handle of this invention can be directly installed at the external connector to achieve the rotation control effect of the control handle on the transmission component. By setting external connectors at both ends of the shaft of the transmission rod, the control handle can control the transmission component from any position. A driven component is installed on the transmission rod, and the driven component is set as the main component of the lifting and bearing component. In order to ensure the balance of the bearing component, the two sets of transmission rods with driven components are connected by a synchronous shaft, which realizes the stable synchronous movement of the two sets of transmission rods and ensures the stable lifting and lowering of the bearing component.

[0019] VI. The transmission rod of the present invention is equipped with two sets of wire pulleys, and the wire pulleys are configured to pull the main components of the bearing assembly through steel ropes. In order to make the bearing assembly more stable as a whole, leaf springs are directly added to both ends of the fixed block on the transmission rod, so that the wire pulleys can be extended outward through the leaf springs, so that the steel rope and the bearing assembly form an inverted trapezoidal structure, which steadily increases the stability of the bearing assembly.

[0020] VII. Guide cylinders are installed at the protruding ends of the walking platform of the present invention. The guide cylinders are designed as vertical structures and are equipped with steel cables. The guide cylinders assist in guiding the steel cables and avoid the problem of damage caused by contact between the steel cables and the inspection vehicle body. The walking platform is designed as an arc-shaped structure, which has a more stable function of supporting the inspection vehicle. The protruding strips on the walking platform are designed to help fix the inspection vehicle body and prevent the inspection vehicle from slipping. Attached Figure Description

[0035] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0036] Example: Please refer to Figures 1 to 9:

[0037] This invention provides a pipeline inspection auxiliary hoisting engineering vehicle, including a frame assembly 1. A rotating assembly 3 is rotatably mounted on the upper end of the frame assembly 1. An auxiliary assembly 2 is arranged on the left side of the frame assembly 1 at the lower end of the rotating assembly 3. Transmission assemblies 4 are installed at the front and rear ends of the top of the rotating assembly 3. Control handles 8 are installed at both the transmission assembly 4 and the rotating assembly 3. A driven assembly 5 is installed on each transmission assembly 4. The lower end of the driven assembly 5 is connected to a bearing assembly 6. The bearing assembly 6 penetrates into the interior of the pipeline well 7.

[0038] The frame assembly 1 has a rectangular frame structure for its support frame 101. Bottom wheels 102 are fixed at the bottom corners of the support frame 101. The bottom wheels 102 are installed at the bottom of the four corners of the support frame 101, making the support frame 101 with bottom wheels 102 easy to move. At the same time, the bottom wheels 102 are designed to be locked, so as to fix the entire frame assembly 1 in a designated position. A mounting rod 103 is provided on the right side of the support frame 101. A handlebar 104 is hinged to the outer end of the mounting rod 103 on the support frame 101. The handlebar 104 is inclined near its end. Since the handlebar 104 is hinged, in order to avoid the end bracket of the handlebar 104 from contacting the rotating component 3 and other components when the handlebar 104 is closed, the end of the handlebar 104 is directly inclined, thus avoiding damage to the rotating component 3 and other components by the end of the handlebar 104.

[0039] In this design, the support column 201 of the auxiliary component 2 is located at the lower left side of the rotating component 3. A horizontal support plate 202 is fixed at the bottom of the support column 201, and the support plate 202 supports the testing instruments and cable winches. A guide wheel 203 is installed on the middle right side of the support plate 202. The horizontal support plate 202 at the support column 201 allows the auxiliary component 2 to support the testing instruments inside the frame component 1. The cable winch is also installed on the support plate 202, thus ensuring the support column supports the testing instruments. The guide wheel 203 at the carrier plate 202 guides the cable of the winch. The guide wheel 203 installed on the bearing assembly 6 also guides the cable for detecting the position of the vehicle body. Two sets of vertical limiting plates 204 are set at the right end of the carrier plate 202. The two sets of limiting plates 204 at the right end of the carrier plate 202 help to block the detection instruments and other equipment carried by the carrier plate 202, so as to prevent the equipment and other instruments from sliding and falling into the pipe well 7.

[0040] The mounting ring 301 of the rotating assembly 3 is configured as an annular structure and is fixed to the top of the frame assembly 1. A rotating ring 302 is rotatably mounted on the mounting ring 301. A slot is provided at the left end of the mounting ring 301, and a mounting bracket 304 is installed at the inner end of the slot. A horizontal shaft is provided on the mounting bracket 304, and a positioning block 303 is sleeved on the shaft of the mounting bracket 304. A spring is installed between the positioning block 303 and the mounting bracket 304. A control handle 8 is sleeved on the outer end of the shaft of the mounting bracket 304. The control handle 8 is initially configured as... The device has a detachable control handle, which allows the control handle 8 to be fitted onto the shaft of the mounting bracket 304. The control handle 8 presses the positioning block 303 on the shaft of the mounting bracket 304 inward, causing the positioning block 303 to disengage from the rotating ring 302. When the control handle 8 is rotated, it drives the rotating ring 302, thereby adjusting the rotation of the rotating component 3. Similarly, after the control handle 8 is removed, the positioning block 303 rests against the inner wall of the rotating ring 302, thus fixing the rotating component 3 in a circumferential rotation.

[0041] In this transmission assembly 4, the transmission rod 401 has a long shaft structure. The transmission rod 401 is rotatably mounted on the upper end of the rotating ring 302. The transmission rod 401 is configured in two sets, front and rear. Both ends of the transmission rod 401 are provided with external connectors 403, which are hexagonal prism structures. By configuring the external connectors 403 as hexagonal prisms, the control handle 8 can be directly mounted at the external connectors 403, thereby achieving the rotation control effect of the control handle 8 on the transmission assembly 4. Furthermore, by providing external connectors 403 at both ends of the shaft of the transmission rod 401, the control handle 8 can move through any position. Both can control the transmission component 4. A synchronous shaft 402 is installed on the left side between the two sets of transmission rods 401. The synchronous shaft 402 is connected to both sets of transmission rods 401 through bevel gears. Since the driven component 5 is installed on the transmission rod 401, and the driven component 5 is set as the main component of the lifting and bearing component 6, in order to ensure the balance of the bearing component 6, the two sets of transmission rods 401 with the driven component 5 are connected to each other through the synchronous shaft 402, so that the two sets of transmission rods 401 form a stable synchronous movement, ensuring the stable lifting and lowering of the bearing component 6.

[0042] In this configuration, the driven assembly 5's reel drum 501 is sleeved and mounted on the shaft of the transmission rod 401. The inner wall of the reel drum 501 has protrusions, and the shaft wall of the transmission rod 401 has grooves corresponding to these protrusions. By sleeved and mounted on the transmission rod 401, the protrusions on the reel drum 501 correspond to the grooves on the transmission rod 401, enabling the reel drum 501 to slide axially on the transmission rod 401. Simultaneously, the reel drum 501 is fixed in the circumferential direction of the transmission rod 401, achieving the transmission effect of the transmission rod 401 sliding and rotating the reel drum 501. Two sets of wire pulleys 501 are installed. A fixing block 502 is set in the middle of the transmission rod 401. Leaf springs 503 are set at both ends of the fixing block 502. The fixing block 502 is set in the middle of the transmission rod 401. Since two sets of wire pulleys 501 are installed on the transmission rod 401, and the wire pulleys 501 are set as the main components that pull the bearing assembly 6 through the steel rope, leaf springs 503 are directly added to both ends of the fixing block 502 on the transmission rod 401 to make the bearing assembly 6 more stable. The wire pulleys 501 are extended outward through the leaf springs 503, so that the steel rope and the bearing assembly 6 form an inverted trapezoidal structure, which stably increases the stability of the bearing assembly 6.

[0043] The spool 501 has rotating frames 504 rotatably mounted on both outer sides of its two ends. A sliding frame 505 is installed between the rotating frames 504. The sliding frame 505 has a groove, and a guide buckle 506 is slidably installed in the groove of the sliding frame 505. The guide buckle 506 has a hole through which a steel rope is inserted. In order to ensure that the steel rope can be stably wound into the spool 501, the rotating frame 504 with the sliding frame 505 is directly rotatably mounted on the spool 501. The guide buckle 506, which slides in the groove of the sliding frame 505, is always on the spool 501, thereby achieving the stable introduction of the steel rope into the spool 501.

[0044] The walking platform 601 of the supporting component 6 has protruding heads at its front and rear edges. Guide cylinders 602 are snapped onto the protruding heads of the walking platform 601. Steel ropes are embedded and fixed inside the guide cylinders 602. The guide cylinders 602 are installed on the protruding heads at both ends of the walking platform 601. The guide cylinders 602 are designed as vertical structures and have steel ropes installed on them. This allows the guide cylinders 602 to assist in guiding the steel ropes and avoids the problem of the steel ropes coming into contact with and being damaged by the inspection vehicle. The upper end face of the walking platform 601 is designed as an arc-shaped structure. A protruding strip 603 is provided at the arc-shaped position of the walking platform 601. The arc-shaped structure of the walking platform 601 provides a more stable support for the inspection vehicle. The protruding strip 603 on the walking platform 601 helps to fix the inspection vehicle and prevent the inspection vehicle from slipping.

[0045] The top of the control handle 8 is sleeve-shaped, the inner wall of the sleeve of the control handle 8 is hexagonal, the outer end of the sleeve is provided with an annular groove, and the outer wall of the sleeve is provided with gear teeth. First, the control handle 8 is set to be used for multiple functions. The inner wall of the sleeve of the control handle 8 is set to a hexagonal structure so that the sleeve of the control handle 8 can be stably installed on the outer connector 403. The gear tooth structure set on the outer wall of the sleeve allows the control handle 8 to realize the transmission control of the sleeve of the control handle 8 to the rotating ring 302 when it is installed at the rotating component 3.

[0046] The specific usage and function of this embodiment: In this invention, bottom wheels 102 are installed at the bottom positions of the four corners of the support frame 101, making the support frame 101 with bottom wheels 102 easy to move. At the same time, the bottom wheels 102 are designed with a locking structure to facilitate fixing the entire frame assembly 1 in a designated position. A horizontal support plate 202 is set at the support column 201, which serves to allow the auxiliary assembly 2 to perform load-bearing detection instruments inside the frame assembly 1. A winch for cables is also installed on the support plate 202, so the guide wheel 203 set at the support plate 202 has the function of guiding the winch cable. The guide wheel 203 installed on the support assembly 6 also guides the cable for detecting the position of the vehicle body. Firstly, the control handle 8 is set as a detachable control handle of the device. The control handle 8 is then fitted onto the shaft of the mounting bracket 304, allowing it to press the positioning block 303 on the shaft of the mounting bracket 304 inwards, causing the positioning block 303 to disengage from the rotating ring 302. Rotating the control handle 8 then drives the rotating ring 302, achieving the function of adjusting the rotation of the rotating component 3. Similarly, after removing the control handle 8, the positioning block 303 again presses against the inner wall of the rotating ring 302, thus achieving the function of fixing the circumferential rotation of the rotating component 3. The outer connector 403 is set as a hexagonal prism structure, allowing the control handle 8 to be directly installed at the outer connector 403, enabling the control handle 8 to control the transmission assembly. The rotation control effect of component 4 is achieved by setting external joints 403 at both ends of the shaft of transmission rod 401, so that the control handle 8 can control the transmission component 4 from any position. Since driven component 5 is installed on transmission rod 401, and driven component 5 is set as the main component of lifting and lowering load-bearing component 6, in order to ensure the balance of load-bearing component 6, the two sets of transmission rods 401 with driven component 5 are connected by synchronous shaft 402, so that the two sets of transmission rods 401 form a stable synchronous movement, ensuring the stable lifting and lowering of load-bearing component 6. Two sets of pulley drums 501 are installed on transmission rod 401, and pulley drums 501 are set as the main components that pull load-bearing component 6 through steel rope, so as to make the load-bearing component 6 more stable as a whole. To ensure stability, leaf springs 503 are added to both ends of the fixed block 502 on the transmission rod 401, allowing the wire pulley 501 to expand outward through the leaf springs 503. This creates an inverted trapezoidal structure between the steel rope and the load-bearing component 6, significantly increasing the stability of the load-bearing component 6. Guide cylinders 602 are installed on the protruding ends of the walking platform 601. The guide cylinders 602 are designed as vertical structures and also have steel ropes attached to them. This allows the guide cylinders 602 to assist in guiding the steel ropes and avoids damage from contact between the steel ropes and the inspection vehicle body. The walking platform 601 is designed as an arc-shaped structure, providing a more stable load-bearing function for the inspection vehicle. Protruding strips 603 are also provided on the walking platform 601 to help fix the inspection vehicle body and prevent it from slipping.
