Description

[0001] The invention relates to the technical field of transport vehicles, in particular to a transport vehicle with a height detection mechanism. Background Art

[0002] At present, when transporting goods on the market, transport vehicles are generally used for loading. When passing through some height-limited frames or the bottom of viaducts, the driver is required to judge the height limit. Once the judgment fails, the transport truck is often stuck at the bottom of the height-limited frame. Although there are some height-limited frames with elevation settings, the height limit data is often non-standard and there are errors in actual use, which leads to transportation or jamming. In some places without height limit signs, some truck drivers often try to move forward, or when the transport truck moves to the bottom of the height limit, the truck driver gets off the vehicle to check and then moves forward. This method will lead to low travel efficiency and there will be or jamming situations, causing huge economic losses. Therefore, in view of the above problems, a transport vehicle with a height detection mechanism is proposed. Summary of the invention

[0010] At present, when transporting goods on the market, transport vehicles are generally used for loading. When passing through some height-limited frames or the bottom of viaducts, drivers are required to judge the height limit. Once the judgment fails, the transport truck is often stuck at the bottom of the height-limited frame. Although there are some height-limited frames with elevation settings, the height limit data is often non-standard and there are errors in actual use, which leads to transportation or jamming. In some places where there are no height-limited signs, some truck drivers often try to move, or when the transport truck moves to the bottom of the height limit, the truck driver gets off the car to check and move. This method will lead to low travel efficiency and the existence of or jamming, causing huge economic losses. When in use, when the transport truck moves to the height-limited position, the height detection mechanism is driven to extend the height detection frame by starting the adjustment mechanism. At this time, the second motor inside the height detection mechanism is started, the second motor drives the threaded rod to rotate, the threaded rod drives the moving cylinder to move, and the moving cylinder drives the moving frame to move. At this time, the rangefinder above the moving cylinder extends out, and the distance measurement process can be performed on the bottom of the height-limited frame or viaduct to ensure that the transport truck passes the height-limited position smoothly.

[0011] As an optional solution of the transport vehicle with a height detection mechanism described in the present invention, the adjustment mechanism includes an adjustment frame, a connecting frame and a first motor, the outer side of the adjustment frame is rotatably connected to the connecting frame, one side of the connecting frame is fixedly connected to the mounting plate, the outer side of the adjustment frame is fixedly connected to the level meter, and the bottom of the adjustment frame is fixedly connected to the guide frame;

[0012] A first motor is fixedly connected inside the adjustment frame, a threaded shaft is fixedly connected to the end of the main shaft of the first motor, a movable sleeve is spirally connected to the outer side of the threaded shaft, and the other side of the movable sleeve is fixedly connected to the height detection mechanism.

[0013] As an optional solution of the transport vehicle with a height detection mechanism described in the present invention, the bottom of the movable sleeve is fixedly connected to a limit plate, and one side of the limit plate is slidably connected to the adjustment frame.

[0014] When measuring the height, the first motor is started to drive the threaded shaft to rotate, and the threaded shaft drives the movable sleeve to move. At this time, the height detection mechanism can be driven to extend the height detection frame for measuring the height, and the set limit plate can ensure the stable movement of the movable sleeve to prevent its own rotation.

[0015] As an optional solution of the transport vehicle with a height detection mechanism described in the present invention, there are two groups of movable frames, and the movable frames are fixedly connected to the side facing the rotating cylinder with a fixed frame, and the outer side of the fixed frame is slidably connected to the rotating cylinder.

[0017] By starting the third motor to drive the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the mobile frame to rotate. At this time, it can be ensured that the rangefinder inside the mobile frame is in a horizontal state, ensuring that its height measurement data is accurate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] When the present invention is in use, when the transport truck moves to the height-limited position, the height detection mechanism is driven to extend the height detection frame by starting the adjustment mechanism, and at this time, the second motor inside the height detection mechanism is started, the second motor drives the threaded rod to rotate, the threaded rod drives the moving cylinder to move, and the moving cylinder drives the moving frame to move, and at this time, the rangefinder above the moving cylinder extends out, and at this time, the height-limited frame or the bottom of the viaduct can be measured to ensure that the transport truck passes the height-limited position smoothly;

[0020] In actual use, the road surface may be uneven, which will cause the distance meter to measure inaccurately. The device uses a level meter to detect whether the adjustment mechanism is horizontal, and the second hydraulic rod drives the sliding block to move. The sliding block slides inside the guide frame. At this time, the angle of the adjustment mechanism can be adjusted to ensure that the distance meter is in a horizontal state and the measurement data is accurate.

[0021] By starting the third motor to drive the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the mobile frame to rotate. At this time, the rangefinder inside the mobile frame can be kept in a horizontal state, ensuring that its height measurement data is accurate;

[0022] By starting the first hydraulic rod to drive the movable plate upward, the infrared altimeter on the outer side of the movable plate can measure the height of the transport carriage, and compare its height with the measured height to determine whether the transport truck can pass smoothly.

DETAILED DESCRIPTION

[0029] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 , the present invention provides a technical solution:

[0030] A transport vehicle with a height detection mechanism, comprising a transport head 1, a transport carriage 2 and a height detection frame 3;

[0031] A transport carriage 2 is installed on one side of the transport head 1, and a height detection frame 3 is fixedly connected to the top of the transport head 1;

[0032] The interior of the height detection frame 3 is fixedly connected with a mounting plate 4, one side of the mounting plate 4 is fixedly connected with an adjustment mechanism 6, and the other end of the adjustment mechanism 6 is fixedly connected with a height detection mechanism 7, the top of the adjustment mechanism 6 is fixedly connected with a level meter 8, one side of the mounting plate 4 is rotatably connected with a second hydraulic rod 9, the other end of the second hydraulic rod 9 is rotatably connected with a sliding block 10, the top of the sliding block 10 is slidably connected with a guide frame 11, and the top of the guide frame 11 is fixedly connected with the adjustment mechanism 6;

[0033] A first hydraulic rod 5 is fixedly connected inside the mounting plate 4 , a movable plate 12 is fixedly connected to the top of the first hydraulic rod 5 , and an infrared altimeter 13 for measuring the height of the transport carriage 2 is installed on one side of the movable plate 12 .

[0034] The height detection mechanism 7 comprises a fixed cylinder 711, a rotating cylinder 701, a second motor 702 and a threaded rod 703. One side of the fixed cylinder 711 is fixedly connected to the adjustment mechanism 6. The rotating cylinder 701 is rotatably connected inside the fixed cylinder 711. The second motor 702 is fixedly connected to the outer side of the rotating cylinder 701. The two main shafts of the second motor 702 are fixedly connected to the threaded rod 703. The outer side of the threaded rod 703 is spirally connected to the moving cylinder 704. The other end of the moving cylinder 704 is fixedly connected to the moving frame 706. The top of the moving cylinder 704 is fixedly connected to a rangefinder 705.

[0035] At present, when transporting goods on the market, transport vehicles are generally used for loading. When passing through some height-limited frames or the bottom of viaducts, the driver is required to judge the height limit. Once the judgment fails, the transport truck is often stuck at the bottom of the height-limited frame. Although there are some height-limited frames with elevation settings, the height limit data is often non-standard and there are errors in actual use, which leads to transportation or getting stuck. In some places without height limit signs, some truck drivers often try to move forward, or when the transport truck moves to the bottom of the height limit, the truck driver gets off the vehicle to check and then moves forward. This method will lead to low travel efficiency and the possibility of jamming, resulting in huge economic losses. When in use, when the transport truck moves to the height limit position, the height detection mechanism 7 is driven to extend the height detection frame 3 by starting the adjustment mechanism 6. At this time, the second motor 702 inside the height detection mechanism 7 is started, and the second motor 702 drives the threaded rod 703 to rotate, and the threaded rod 703 drives the moving cylinder 704 to move, and the moving cylinder 704 drives the moving frame 706 to move. At this time, the rangefinder 705 above the moving cylinder 704 is extended, and the distance measurement process can be performed on the height limit frame or the bottom of the viaduct to ensure that the transport truck passes the height limit position smoothly.

[0036] In this embodiment, in actual use, the road surface may be uneven sometimes, which will cause the distance meter 705 to measure the height inaccurately. The device detects whether the adjustment mechanism 6 is horizontal through the level meter 8, and has driven the sliding block 10 to move through the second hydraulic rod 9. The sliding block 10 slides inside the guide frame 11. At this time, the angle of the adjustment mechanism 6 can be adjusted to ensure that the distance meter 705 is in a horizontal state and the measurement data is accurate. The second motor 702 is a double-output shaft motor, which can drive the threaded rods 703 on both sides to rotate synchronously, so that the distance meters 705 on both sides can be extended and detected;

[0037] By starting the first hydraulic rod 5 to drive the movable plate 12 to move upward, the infrared altimeter 13 outside the movable plate 12 can measure the height of the transport carriage 2, and compare its height with the measured height to determine whether the transport truck can pass smoothly.

[0038] Example 2: This example is an improvement on Example 1. Figure 3 Specifically, the adjustment mechanism 6 includes an adjustment frame 601, a connecting frame 602 and a first motor 603. The outer side of the adjustment frame 601 is rotatably connected to the connecting frame 602. One side of the connecting frame 602 is fixedly connected to the mounting plate 4. The outer side of the adjustment frame 601 is fixedly connected to the level 8. The bottom of the adjustment frame 601 is fixedly connected to the guide frame 11.

[0039] The inside of the adjustment frame 601 is fixedly connected with a first motor 603 , the end of the main shaft of the first motor 603 is fixedly connected with a threaded shaft 604 , the outer side of the threaded shaft 604 is spirally connected with a movable sleeve 605 , and the other side of the movable sleeve 605 is fixedly connected to the height detection mechanism 7 .

[0040] The bottom of the movable sleeve 605 is fixedly connected to a limiting plate 606 , and one side of the limiting plate 606 is slidably connected to the adjustment frame 601 .

[0041] When measuring the height, the first motor 603 is started to drive the threaded shaft 604 to rotate, and the threaded shaft 604 drives the movable sleeve 605 to move. At this time, the height detection mechanism 7 can be driven to extend the height detection frame 3 for measuring the height, and the set limit plate 606 can ensure the stable movement of the movable sleeve 605 to prevent its own rotation.

[0042] Example 3: This example is an improvement on Example 1. Figure 4 and Figure 5 Specifically, there are two groups of movable frames 706 , and a fixed frame 707 is fixedly connected to one side of the movable frame 706 facing the rotating cylinder 701 , and an outer side of the fixed frame 707 is slidably connected to the rotating cylinder 701 .

[0043] The third motor 709 is also fixedly connected inside the fixed cylinder 711 , and the end of the main shaft of the third motor 709 is fixedly connected to a gear 710 . The outer side of the gear 710 is meshed with a gear ring 708 , and the outer side of the gear ring 708 is fixedly connected to the moving frame 706 .

[0044] By starting the third motor 709 to drive the gear 710 to rotate, the gear 710 drives the gear ring 708 to rotate, and the gear ring 708 drives the mobile frame 706 to rotate. At this time, it can be ensured that the rangefinder 705 inside the mobile frame 706 is in a horizontal state, ensuring that its height measurement data is accurate.
