Description

Technical Field

[0001] The utility model belongs to the technical field of lifting machinery detection devices, especially a crane track measuring vehicle. Background Technique

[0002] The crane running track is an important part of the crane. A common problem that often occurs during the operation of the crane running on the track is wheel rail biting, where the wheel flange and the side of the track generate severe friction, resulting in wear and deformation of both the wheel flange and the track, affecting the safe operation of the crane; when the rail biting is severe, derailment accidents may occur. Therefore, it is necessary to measure the track and evaluate its installation quality.

[0003] The existing Chinese patent publication number CN218754643U discloses a device for measuring crane tracks. This solution can adapt to crane tracks of different models and sizes and can firmly fix the prism on the support; however, there has not yet appeared a detection device with a simple structure and stable measurement in the prior art.

[0023] The following combines the drawings and specific embodiments to elaborate on the utility model in detail.

[0024] Please refer to Figure 1 As shown, in an embodiment of the utility model, a crane track measuring vehicle includes a chassis 1. A pair of motor fixing compartments 7 are respectively hinged to the front side and the rear side of the chassis 1. A spring 11 is arranged between the pair of motor fixing compartments 7. A battery compartment 2 is fixedly connected above the chassis 1. A battery is arranged in the battery compartment 2. The battery is connected to a driving device. The driving device is fixedly connected with a driving wheel shaft 10 below. The driving device is arranged on the motor fixing compartment 7. A motor cover plate 8 for protecting the driving device is fixed on the motor fixing compartment 7. A prism 3 is fixedly connected to the top of the battery compartment 2.

[0025] Refer to Figure 2, during operation, first, open the two pairs of motor fixing bins outward, place the measuring vehicle on the crane track 12. Under the action of spring tension, the driving wheel shafts at the bottom of each pair of motor fixing bins clamp both sides of the crane track, and the driving wheel shafts can stably fit on the side wall of a single track. The driving device drives the driving wheel shafts to rotate, thereby enabling the entire measuring vehicle to run along the crane track. The crane track is detected through a prism, and the angle of the prism can be adjusted according to measurement needs. The measuring vehicle is powered by a battery.

[0026] Furthermore, the battery can adopt a lithium battery power supply to ensure that the measuring vehicle can work continuously for more than 8 hours.

[0027] Please refer to Figure 1 As shown, in an embodiment of the present invention, a wireless receiver 9 for receiving signals is fixed on the top of the battery bin 2. The wireless receiver 9 is connected to a controller, and the controller controls the movement of the trolley. The wireless receiver 9 is connected to the driving device for signal interaction.

[0028] In addition, the measurement information can also be transmitted to a tablet computer or a laptop computer through the wireless receiver by means of WiFi communication to ensure the efficiency and reliability of data transmission; at the same time, the wireless sensor continuously receives the execution command signals sent by the tablet computer or the laptop computer, and the driving device drives the driving wheel shafts to rotate to achieve the measurement function.

[0029] In an embodiment of the present invention, an infrared sensor is provided on the chassis to prevent the measuring vehicle from falling when running to both ends of the guide rail.

[0030] In another embodiment of the present invention, the driving device is a permanent magnet synchronous motor, and a magnet cover plate is directly fixed between the chassis and the battery bin; the magnet cover plate plays a protective role for the battery in the battery bin. The permanent magnet synchronous motor is used in conjunction with the field-oriented control (FOC) algorithm, and is combined with the high-precision angle sensor built in the motor to achieve precise control of the motor torque and the motor position. At the same time, the motor driver has a complete and reliable motor on-board diagnostic (OBD) monitoring mechanism and protection function to ensure the safe and reliable operation of the motor. Among them, the reduction gear uses a new harmonic meshing tooth profile "P tooth profile", which overcomes the disadvantages of the previous harmonic meshing, greatly improving the service life of the flexspline. At the same time, due to the characteristic of relatively low tooth height, a large meshing amount can be obtained without a very deep meshing distance, and it can withstand a large torque.

[0031] Please refer to Figure 1 As shown, in an embodiment of the present invention, a battery upper cover plate 5 is fixedly connected above the battery bin 2, and a battery lower cover plate 6 is fixedly connected below; the battery upper cover plate 5 and the battery lower cover plate 6 are used to fix the battery and also play a protective role.

[0032] Please refer to Figure 1As shown, in one embodiment of the utility model, the prism 3 is a 360° prism, and the 360° prism is fixed above the battery upper cover; the 360° prism can perform all-round reflection, and the measurement effect is better.

[0033] See also Figure 1 As shown, in one embodiment of the utility model, the motor fixing compartment 7 includes a motor baffle 4, which is protruded upward on all sides to form an enclosure shape, and a motor cover 8 is fixed above the motor baffle 4. The motor cover 8 is tightly combined with the motor baffle 4 and fixedly connected by bolts. The structure is stable, and at the same time, it plays a role in fixing and protecting the drive device.

[0034] In another embodiment of the utility model, a power interface is provided on the battery upper cover plate 5. The power interface is used to charge the battery with an external power source.

[0035] In another embodiment of the present invention, the driving wheel shaft 10 is a flexible rolling wheel, which may be a double-layer rubber wheel.

[0036] The chassis 1 of the utility model has the characteristics of high load-to-weight ratio and strong adaptability to curved surfaces, and can be applied to regional operations on crane tracks.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
