Description

Technical Field

[0001] This utility model relates to the field of belt conveyor inspection vehicles, and in particular to a special inspection vehicle for overhead cable belt conveyors. Background Technology

[0002] Cable-stayed belt conveyors, as material conveying equipment adapted to special terrains, are widely used in complex geographical environments such as plateaus and mountains due to their significant advantages, including long spans, minimal terrain limitations, short construction periods, and low steel structure requirements. Compared to traditional belt conveyors, their suspension structure enables the conveyor belt to be erected at high altitudes, greatly reducing the difficulty of foundation construction and civil engineering costs. However, the unique nature of this structure presents unique challenges to its operation and maintenance.

[0003] The inspection method for cable belt conveyors differs from that of traditional belt conveyors located on the ground. Traditional belt conveyor inspections typically involve an inspection trolley traveling on the ground to different locations on the conveyor for inspection. The structure of this inspection trolley is clearly unsuitable for the inspection of cable belt conveyors that are suspended in the air, and it is also necessary to ensure the stability and safety of the inspection trolley during its operation. Utility Model Content

[0004] In order to overcome the problems in the background art mentioned above, this utility model provides a special inspection vehicle for overhead cable belt conveyors. By setting up an inspection vehicle suitable for traveling on suspended high-altitude tracks, it is convenient to inspect overhead cable conveyors, and has the beneficial effects of good stability and safety.

[0005] The technical solution of this utility model is as follows:

[0006] A special inspection vehicle for an overhead cable belt conveyor includes an inspection vehicle body. The inspection vehicle body is provided with traveling wheels that are connected to an overhead track at the bottom. The inspection vehicle body can move back and forth along the overhead track under the action of a traction device.

[0007] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0008] By incorporating wheels in the inspection vehicle body that connect with the elevated track, the inspection vehicle can travel on the elevated track and inspect the cable conveyor, thus solving the problem in the prior art where existing ground-based inspection trolleys cannot inspect cable conveyors. Furthermore, the inspection vehicle body travels on the elevated track via a traction device, ensuring stability and safety during travel.

[0009] Preferably, the inspection vehicle body includes a frame longitudinal beam arranged along the length of the elevated track and a frame crossbeam passing through the frame longitudinal beam; the traveling wheels are arranged at the bottom of the frame longitudinal beam.

[0010] More preferably, the frame has two longitudinal beams, and the two ends of the frame crossbeams pass vertically through the middle of the frame longitudinal beams and are fixedly connected to them; each frame longitudinal beam has a wheel on the front and rear sides at the bottom.

[0011] Its beneficial effects are as follows: This configuration is conducive to the overall balance of the inspection vehicle body, so that the inspection vehicle body remains stable during driving. The two ends of the frame crossbeam extend through the frame longitudinal beam, which facilitates the suspension of the basket. The inspection vehicle body is supported by four wheels in the front, rear, left and right, which can better balance and move more stably.

[0012] More preferably, two baskets are suspended below the two ends of the vehicle frame crossbeam, and the two baskets are arranged symmetrically; the baskets are fixed to the vehicle frame crossbeam by means of suspension rods.

[0013] Its beneficial effects are as follows: the suspended basket is used to carry large tools and inspection personnel for inspection and replacement work. By setting up two suspended baskets, the loading capacity of the inspection vehicle is increased, and it also helps to improve the overall balance of the inspection vehicle. In addition, the two suspended baskets are suspended below the left and right sides of the inspection vehicle, which can lower the center of gravity of the inspection vehicle, making the inspection vehicle more stable when moving. The boom is used to fix the suspended basket to the inspection vehicle body.

[0014] More preferably, the top of the boom extends upward and passes vertically through the end of the frame crossbeam. An end plate is fixed to the side of the end of the frame crossbeam. Fasteners pass through the end plate and the boom body to fix the two together. The lower part of the boom is fixedly connected to the side of the basket by fasteners. The basket is equipped with a storage box and has climbing poles arranged around its circumference for people to climb.

[0015] Its advantages are: the climbing pole makes it easy for maintenance personnel to go up and down the basket to maintain the conveyor, while the storage box is used to store some commonly used maintenance tools and a small number of spare parts.

[0016] More preferably, the traveling wheel is provided with annular grooves that match the structure of the elevated track; the elevated track is erected on the truss of the conveyor and is made of steel rails or steel wire ropes.

[0017] Its beneficial effects are as follows: by laying the high-altitude track on the truss and having the inspection vehicle pass over the high-altitude track, the inspection vehicle is positioned above the conveyor, while the basket is suspended below the inspection vehicle. This allows the inspection personnel inside the basket to more easily inspect the main components of the conveyor (such as the idler roller assembly structure), and also makes it easier for them to reach the conveyor from inside the basket to replace components.

[0018] More preferably, a wheel frame is fixed to the bottom of the longitudinal beam of the vehicle frame, the traveling wheel is installed in the wheel frame, and slots are opened on both sides of the wheel frame. The two ends of the axle of the traveling wheel pass through the slots and are fixed in the slots by a plate.

[0019] Its beneficial effects are: by setting up a wheel frame for mounting the traveling wheels, and by setting up a clamping plate, the axle of the traveling wheels can be stably placed in the clamping groove.

[0020] More preferably, the traction device includes a traction rope and a drive device. The traction rope is in the form of a loop, with one side wound around the drive device and the other side passing through the front of the inspection vehicle body and exiting from its rear.

[0021] Its beneficial effects are as follows: the inspection vehicle moves back and forth by the traction force of the traction rope, which can stabilize the wheels on both sides of the inspection vehicle on the high-altitude track, so that it can travel smoothly on the high-altitude track and avoid safety hazards such as derailment, thereby improving the stability and safety of the inspection vehicle during operation.

[0022] More preferably, the drive device is a variable frequency winch, which drives the inspection vehicle body to move back and forth by rotating the motor forward and backward via the traction rope.

[0023] Its beneficial effects are as follows: the inspection vehicle moves back and forth by the traction force of the traction rope, which can stabilize the wheels on both sides of the inspection vehicle on the high-altitude track, so that it can travel smoothly on the high-altitude track and avoid safety hazards such as derailment, thereby improving the stability and safety of the inspection vehicle during operation.

[0024] More preferably, the crossbeam of the vehicle frame is fixed with a rope-pressing plate, and the rope-pressing plate extends downwards to its end with two clamps for fixing the traction rope. The two clamps extend along the running direction of the inspection vehicle body, and the opposite side of the two clamps has fixing holes for fixing the traction rope. There are two sets of fixing holes arranged vertically and parallel to each other, and the two ends of the traction rope are respectively embedded in the corresponding fixing holes. The length of the fixing holes ranges from 1100 to 1200 mm. The two clamps are fixedly connected by fasteners, and the two sets of fixing holes are located on the centerline of the inspection vehicle body in the running direction.

[0025] Its beneficial effects are as follows: the two clamps clamp and fix the two ends of the traction rope in the fixing holes; increasing the contact area between the end of the traction rope and the fixing holes can ensure the stability of the connection between the two, so that the traction rope can more reliably drive the inspection vehicle body to move; the two sets of fixing holes are located on the center line of the inspection vehicle body, which can make the traction force applied by the traction rope to the inspection vehicle body in the middle of the inspection vehicle body, avoiding the imbalance of force on both sides of the inspection vehicle body and the resulting tilt, which would lead to poor stability and, in severe cases, a rollover accident.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1: As Figures 1 to 4 The diagram illustrates a dedicated inspection vehicle for overhead cable conveyors. It includes a vehicle body with wheels 11 mounted below it, which connect to an elevated track 2. The vehicle body can move back and forth along the elevated track 2 under the action of a traction device. Therefore, by incorporating wheels 11 in the vehicle body that connect to the elevated track 2, the inspection vehicle can travel on the elevated track 2 and inspect the cable conveyor, solving the problem in the prior art where existing ground-based inspection trolleys cannot inspect cable conveyors. Furthermore, the vehicle body's movement on the elevated track 2 via the traction device ensures stability and safety during operation.

[0034] Example 2: Based on Example 1, the structure of the inspection vehicle body is optimized, such as... Figure 1 and Figure 3As shown, the inspection vehicle body includes a frame longitudinal beam 12 arranged along the length of the elevated track 2 and a frame crossbeam 13 passing through the frame longitudinal beam 12. Specifically, there are two frame longitudinal beams 12, which are respectively arranged directly above the two monorails of the elevated track 2. The two ends of the frame crossbeam 13 pass vertically through the middle of the opposite inner sides of the two frame longitudinal beams 12 and are welded and fixed thereto. This arrangement is beneficial to the overall structural balance of the inspection vehicle body, so that the inspection vehicle body remains stable during operation. The two ends of the frame crossbeam 13 continue to extend outward after passing through the frame longitudinal beam 12, which facilitates the suspension of the basket 3.

[0035] Furthermore, two baskets 3 are suspended below the two ends of the frame crossbeam 13 extending out of the frame longitudinal beam 12. The two baskets 3 are symmetrically arranged on the left and right sides of the inspection vehicle body. The baskets 3 are used to carry large tools and inspection personnel for inspection and replacement work. By setting two baskets 3, the loading capacity of the inspection vehicle body is increased, and it is also beneficial to the overall balance of the inspection vehicle body. In addition, the two baskets 3 are suspended below the left and right sides of the inspection vehicle body, which can also lower the center of gravity of the inspection vehicle body, making the inspection vehicle body more stable when driving.

[0036] In a further preferred embodiment, the suspended basket 3 is fixed to the crossbeam 13 of the vehicle frame via a suspension rod 31, which is used to fix the suspended basket 3 to the inspection vehicle body. Specifically, the top ends of the suspension rods 31 of the two suspended baskets 3 pass vertically upward through the ends of the two crossbeams 13 of the vehicle frame, and end plates 131 are fixed to the outer side of the two crossbeams 13 of the vehicle frame. Fasteners pass horizontally through the end plates 131 and the rods 31 to fix them together. The lower part of the suspension rods 31 is close to the outer side of the suspended basket 3 and is fixedly connected by fasteners. In this embodiment, the fasteners can be bolts and nuts that fit together. The suspended basket 3 is circumferentially arranged with climbing poles 33 for people to climb. A storage box 32 is provided on one side of the suspended basket 3. The climbing poles 33 facilitate maintenance personnel to go up and down the suspended basket 3 to maintain the conveyor 6, and the storage box 32 is used to store some commonly used maintenance tools and a small number of spare parts.

[0037] Furthermore, the wheels 11 are arranged at the bottom of the longitudinal beams 12 of the frame. Each longitudinal beam 12 has a wheel 11 on both the front and rear sides at the bottom. That is, the inspection vehicle body is supported by four wheels 11, which can better balance and move more stably. The wheels 11 are made of nylon material.

[0038] Further preferred, such as Figure 4As shown, the traveling wheel 11 has an annular groove 111 circumferentially formed to match the structure of the elevated track 2. The upper surface of the elevated track 2 is engaged in the annular groove 111, allowing the traveling wheel 11 to roll stably on the surface of the elevated track 2. The elevated track 2 is made of steel rail or steel wire rope. The elevated track 2 is laid on the truss 21 of the conveyor 6 and arranged along its length. The truss 21 is usually arranged above the conveyor 6 and extends along the transport direction. By laying the elevated track 2 on the truss 21, and with the inspection vehicle body passing over the elevated track 2, the inspection vehicle body is located above the conveyor 6, while the basket 3 is suspended below the inspection vehicle body. This allows the inspection personnel in the basket 3 to more conveniently inspect the main components of the conveyor 6 (such as the idler roller assembly structure) and to more easily access the conveyor 6 from the basket 3 for component replacement.

[0039] Further preferred, such as Figures 3 to 4 As shown, a wheel frame 121 is fixed to the bottom of the longitudinal beam 12 of the vehicle frame. The traveling wheel 11 is installed in the wheel frame 121. Slots 122 are respectively opened on both sides of the wheel frame 121. The two ends of the axle 112 of the traveling wheel 11 pass through the slots 122 respectively. A retaining plate 123 is fixed to the two outer sides of the wheel frame 121. The retaining plate 123 is located at the lower part of the slot 122, close to the side of the wheel frame 121, and is fixedly connected to the wheel frame 121 by fasteners. The axle 112 of the traveling wheel 11 passes through the slot 122 and is secured in the slot 122 by the retaining plate 123. The wheel frame 121 is used to install the traveling wheel 11, and the retaining plate 123 ensures that the axle 112 of the traveling wheel 11 is stably located in the slot 122.

[0040] Example 3: Based on the above examples, the traction device is optimized. The traction device includes a traction rope 4 and a drive device. The traction rope 4 is a loop structure, with one side wrapped around the drive device and the other side extending towards the inspection vehicle body. It enters from the front of the inspection vehicle body and exits from the rear, finally returning to the drive device. The inspection vehicle body moves back and forth by the traction force of the traction rope 4. The traction rope 4 can stabilize the wheels 11 on both sides of the inspection vehicle body on the elevated track 2, allowing it to travel smoothly on the elevated track 2 and avoiding safety hazards such as derailment, thus improving the stability and safety of the inspection vehicle body during operation.

[0041] The drive unit is a variable frequency winch, used for winding ropes or wire ropes. The winch is located in the transfer room at the tail end of conveyor 6. The winch uses the forward and reverse rotation of its motor to drive the traction rope 4, moving the inspection vehicle forward and backward. Specifically, the motor's forward and reverse rotation causes the two ends of the traction rope 4 wound on the winch to extend or retract. When one end extends, the other retracts, propelling the inspection vehicle forward; similarly, when one end retracts, the other extends, propelling the vehicle backward. The inspection speed of the vehicle can also be adjusted by changing the motor's speed. Besides being controlled locally, the winch can also be controlled wirelessly. The wireless remote can be mounted on the conveyor tower 6 to increase the remote control distance. When operating the winch using a handheld wireless remote, the winch automatically stops when the finger is removed. If the wireless signal is interfered with or the wireless equipment malfunctions, the winch can also be automatically stopped or returned to a suitable position using local control.

[0042] Furthermore, such as Figures 1 to 2 As shown, a rope-pressing plate 5 is fixed in the middle of the crossbeam 13 of the vehicle frame. The rope-pressing plate 5 extends downward and bends horizontally to one side of the longitudinal beam 12 of the vehicle frame. Two clamping plates 51 are provided at its ends to fix the traction rope 4. The two clamping plates 51 extend along the running direction of the inspection vehicle body. The opposite sides of the two clamping plates 51 are provided with grooves. The two grooves are combined to form a fixing hole 52 for fixing the traction rope 4. The fixing hole 52 is provided in two parallel sets. The two ends 41 of the traction rope 4 are respectively embedded in the corresponding fixing hole 52 and extend outward, respectively extending out of the fixing hole 52 from the front and rear direction of the inspection vehicle body. That is, the two clamping plates 51 clamp and fix the two ends 41 of the traction rope 4 in the fixing hole 52.

[0043] The length of the fixing hole 52 ranges from 1100 to 1200 mm. Increasing the contact area between the end 41 of the traction rope 4 and the fixing hole 52 ensures the stability of the connection between the two, allowing the traction rope 4 to more reliably drive the inspection vehicle body to move. The two clamping plates 51 are tightly fixed together by several fasteners, which are bolts and nuts that are matched and connected. The two sets of fixing holes 52 are located on the center line of the inspection vehicle body, and the direction of the center line is consistent with the driving direction of the inspection vehicle body. This setting allows the traction force applied by the traction rope 4 to the inspection vehicle body to be in the middle of the inspection vehicle body, avoiding the imbalance of force on both sides of the inspection vehicle body and the resulting tilt, which would lead to poor stability and, in severe cases, a rollover accident.

[0044] During inspection, the inspection vehicle is positioned on the elevated track 2, and the traction rope 4 is taut. One end 41 of the traction rope 4 is fixed inside the inspection vehicle, and the rope extends towards the drive device and is wound around the drive device. Then it continues to extend towards the inspection vehicle, and finally, the other end 41 is also fixed inside the inspection vehicle. When the drive device rotates, the traction rope 4 at one end of the inspection vehicle can pull it to travel on the elevated track 2. The forward and reverse rotation direction and speed of the motor of the drive device can change the forward and backward movement direction and speed of the inspection vehicle.

[0045] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
