Description

Technical Field

[0001] The utility model relates to the technical field of water level gauge test trolley driving, in particular to an adjustable driving shock absorbing mechanism and a water level gauge test trolley. Background Art

[0002] The statements in this section merely mention the background technology related to the present invention and do not necessarily constitute the prior art.

[0003] The water level gauge test cart assists in the calibration and testing of water level gauges. The cart uses magnetic navigation sensors at its front and rear ends to perform linear reciprocating motion along a magnetic strip laid on the ground. A proprietary controller controls the drive mechanism's movement. If the magnetic navigation sensor deviates from the magnetic strip, the controller adjusts the drive mechanism's motor speed to adjust the direction of travel. Within a 10-meter test range, the water level gauge test cart must calibrate and test 25-30 points. At each point, the cart is stopped to complete the calibration.

[0004] Therefore, the current water level gauge test trolley mainly realizes the operation of the trolley through the traction of the driving mechanism and the assistance of the driven mechanism. The driving mechanism and the auxiliary driven mechanism are often directly arranged on the chassis of the trolley.

[0005] When the drive mechanism is directly installed on the chassis of the trolley, since the drive wheels in the drive mechanism are directly connected to the motor, when the test trolley encounters a bumpy road surface during operation, the motor will be impacted and damaged due to the weight of the test trolley, thereby affecting the operation of the entire drive mechanism.

[0006] At the same time, the driving mechanism and the driven mechanism in the test trolley work together. Due to the different friction coefficients between different floors (concrete floors, epoxy floors, tiles) and the driving wheels of the driving mechanism, the friction forces are different, and the driving effects are also different.

[0007] Therefore, at present, the driving mechanism and the auxiliary driven mechanism are directly set on the trolley chassis. This form of direct fixed connection cannot adapt to the requirements of different ground surfaces and different loads for the operation of the driving mechanism, and cannot ensure the smooth operation of the test trolley when it makes a straight line back and forth motion along the magnetic strip laid on the ground during the water level gauge calibration and testing process. Utility Model Content

[0008] In order to address the deficiencies of the prior art, the utility model provides an adjustable drive shock-absorbing mechanism for a water level gauge test trolley. Through the shock-absorbing assembly, the impact of the direct connection between the motor and the drive wheel is avoided by buffering through springs and their components on bumpy roads, thereby protecting the motor, extending the service life of the drive mechanism, improving the carrying capacity of the equipment, assisting in the calibration and testing of the water level gauge, and ensuring that the test trolley runs smoothly throughout the entire test process.

[0009] An adjustable drive damping mechanism includes an adapter sleeve, a floating plate, and a damping assembly; one end of the adapter sleeve is sleeved onto the shaft of the motor, and the other end is inserted into the inner hole of the drive wheel, so as to drive the drive wheel to rotate through the rotation of the motor;

[0010] The floating plate is fixedly connected to the motor; flange-type linear sleeves are provided on both the front and rear sides of the floating plate, and the floating plate moves up and down under the action of the shock-absorbing assembly;

[0012] The shock-absorbing limit plate is connected to the fixed plate through a hexagon socket tip set screw, and the height of the limit plate can be adjusted by rotating the hexagon socket tip set screw.

[0013] Furthermore, the hole end of the adapter sleeve is sleeved onto the shaft of the motor and is locked and fixed by a set screw; the shaft end of the adapter sleeve is inserted into the inner hole of the driving wheel and is used in conjunction with a key bar and a shaft retaining ring.

[0014] Furthermore, it also includes a U-shaped bracket and a fixing plate; the U-shaped bracket is fixedly connected to the fixing plate.

[0015] Furthermore, it also includes a positioning shaft, the bottom of the positioning shaft is fixedly connected to the U-shaped bracket through bolts, and the top of the positioning shaft is fixedly connected to the fixing plate through bolts.

[0016] Furthermore, the flange-type linear sleeve is sleeved on the positioning shaft, and rows of balls are placed inside the sleeve, which slide up and down under the action of the shock-absorbing assembly.

[0017] Furthermore, the flange-type linear sleeve is fixed to the front and rear sides of the floating plate by means of hexagon socket bolts.

[0018] Furthermore, two V-shaped positioning holes are evenly distributed on the shock-absorbing limit plate.

[0019] Furthermore, the motor is fixed to the floating plate by means of hexagon socket bolts, and is used to provide power to the adjustable drive damping mechanism to drive the mechanism to operate.

[0020] Furthermore, the number of bolts fixing the motor to the floating plate is four.

[0021] A water level gauge test trolley comprises the aforementioned adjustable drive shock absorbing mechanism and driven wheels; the adjustable drive shock absorbing mechanisms are respectively arranged at the middle and left positions of the water level gauge test trolley to provide power for the trolley to operate;

[0022] The driven wheels are respectively arranged on the four corners of the trolley to provide support for the operation of the trolley.

The shock-absorbing mechanism includes a shock-absorbing spring and a shock-absorbing limit plate.

[0041] It should be noted that the present invention is a construction scheme.

[0042] Example 1

[0043] In order to solve the above problems, the utility model provides an adjustable drive shock absorbing mechanism. Figure 1This is a front view of an adjustable drive damping mechanism, including: a drive wheel 1, a motor 2, a floating plate 3, a fixed plate 4, a U-shaped bracket 5, a positioning shaft 7, a damping compression spring 8, a damping limit plate 9, and a hexagon socket tip set screw 11. A represents a cross-sectional view of the adjustable drive damping mechanism A surface, that is, Figure 7 As shown in the cross-sectional view AA.

[0044] Figure 2 This is a rear view of an adjustable drive shock absorbing mechanism. Figure 3 This is a top view of an adjustable drive shock absorbing mechanism. Figure 4 This is a bottom view of an adjustable drive shock absorbing mechanism. Figure 5 This is a left view of an adjustable drive damping mechanism, wherein B represents a cross-sectional view of the adjustable drive damping mechanism B surface, as shown in FIG. Figure 8 As shown in the cross-sectional view BB.

[0045] Figure 6 This is a right view of an adjustable drive damping mechanism, including: a drive wheel 1, a motor 2, a fixing plate 4, a U-shaped bracket 5, and an adapter sleeve 10. C represents a cross-sectional view of the adjustable drive damping mechanism of the water level gauge test trolley on the C side. Figure 9 As shown in cross-sectional view CC. Figure 9 This is a cross-sectional view CC of an adjustable drive damping mechanism, which includes: a drive wheel 1, a motor 2 and an adapter sleeve 10.

[0046] like Figure 2-Figure 6 and Figure 9 As shown, the hole end of the adapter sleeve 10 is fitted onto the shaft of the motor 2 and is locked and fixed by a set screw; the shaft end of the adapter sleeve 10 is inserted into the inner hole of the drive wheel 1, and the key bar and the shaft retaining spring are used in conjunction with each other to drive the drive wheel to rotate through the adapter sleeve 10 when the motor rotates;

[0047] The motor primarily powers the adjustable damping mechanism. The motor's rotation, through the adapter sleeve, drives the drive wheel, effectively driving the mechanism. The adapter sleeve 10, a custom-made machined part, better connects the motor and drive wheel, ensuring a consistent fit and preventing misalignment.

[0048] During the rotation of the motor, the key bar can prevent the shaft end of the adapter sleeve and the inner hole of the drive wheel from rotating, so that there is no rolling friction between the two; at the same time, a shaft retaining spring is installed on the outside to prevent the drive wheel from running off during movement and reduce axial movement.

[0049] Figure 7 This is a cross-sectional view AA of an adjustable drive shock absorbing mechanism, which includes: a flange-type linear sleeve 6, a shock absorbing compression spring 8, and a shock absorbing limit plate 9.

[0050] Figure 8This is a main view BB of an adjustable drive shock absorbing mechanism, which includes: a flange-type linear sleeve 6, a shock absorbing compression spring 8, a shock absorbing limit plate 9, and a hexagon socket tip set screw 11.

[0051] like Figure 1 and Figure 9 As shown, the motor 2 is fixed to the floating plate 3 by four M5*12mm hexagon socket bolts.

[0052] like Figure 1 、 Figure 6 and Figure 8 As shown, flange-type linear sleeves 6 are provided on both sides of the bottom of the floating plate 3, and are fixed to the front and rear sides of the floating plate 3 by four M4*8mm hexagon socket bolts, and move up and down under the action of the shock-absorbing assembly.

[0053] The shock absorbing assembly includes a shock absorbing compression spring 8 and a shock absorbing limit plate 9. Figure 7 and Figure 8 As shown, a shock-absorbing compression spring 8 is mounted on the outer side of the flange-type linear sleeve 6, and a shock-absorbing limit plate 9 is provided on the top of the shock-absorbing compression spring 8. Two V-shaped positioning holes are evenly distributed on the shock-absorbing limit plate 9. The shock-absorbing limit plate is connected to the fixed plate 4, and a hexagonal tip set screw is provided on the fixed plate 4. The set screw can be rotated with a wrench.

[0054] The shock-absorbing compression spring 8 can be better positioned on the shaft sleeve and will not be deflected due to force; and the shock-absorbing limit plate 9 can protect the spring from being compressed and ensure uniform force.

[0055] V-shaped positioning holes are evenly distributed on the shock-absorbing limit plate, so that when the tip fastening screw is pressed against the V-shaped hole for adjustment, no deviation will occur.

[0056] like Figure 1 、 Figure 6 and Figure 9 As shown, the U-shaped bracket 5 is fixed to the fixing plate 4 with four M6*10mm hexagon socket bolts. The bottom of the positioning shaft 7 is fixed to the U-shaped bracket 5 with bolts, and the top of the positioning shaft 7 is fixed to the fixing plate 4 with bolts. The flanged linear sleeve 6 is used in conjunction with the positioning shaft 7. The flanged linear sleeve is mounted on the positioning shaft and contains rows of balls that slide up and down under the action of the shock-absorbing assembly.

[0057] The U-shaped bracket primarily serves as a lower limit, limiting the downward movement of the motor and drive wheel driven by the floating plate, preventing excessive downward movement. The fixed plate secures the adjustable drive damper to the test vehicle chassis. The drive damper is a single unit, secured to the vehicle via the fixed plate after assembly. The locating shaft connects the fixed plate to the U-shaped bracket and serves primarily as a guide for flanged linear bushings.

[0058] Therefore, the motor drives the driving wheel to rotate, the driving mechanism runs, the motor and the floating plate are fixedly connected, the flange-type linear shaft sleeve is fixedly connected to the front and rear sides of the floating plate, and forms a whole with the floating plate. The flange-type linear shaft sleeve is put on the positioning shaft, and the positioning shaft is fixedly connected to the U-shaped bracket, and the U-shaped bracket is connected to the fixed plate.

[0059] The flange-type linear bushing drives the floating plate to slide up and down along the positioning shaft under the action of the shock-absorbing compression spring, so that the motor fixedly connected to the floating plate drives the drive wheel to move up and down. On bumpy roads, the spring and its components provide buffering to avoid the impact of the direct connection between the motor and the drive wheel, thereby protecting the motor, extending the service life of the drive mechanism, and improving the load-bearing capacity of the equipment.

[0060] like Figure 7 and Figure 8 As shown, a hexagon socket tip set screw is also provided on the fixed plate 4. When the hexagon socket tip set screw is rotated with a wrench, it can be used to adjust the height of the limit plate. Since the shock-absorbing limit plate 9 is connected to the fixed plate 4, the compression degree of the spring can be adjusted by adjusting the height of the limit plate.

[0061] When encountering different ground conditions, the drive shock absorption can be adjusted according to the load of the test trolley and the different ground conditions (concrete floor, epoxy floor, ceramic tile) and the different friction coefficients of the drive wheel of the drive mechanism. By rotating the set screw with a wrench, the height of the limit plate can be adjusted to achieve the compression degree of the shock-absorbing spring to adapt to different ground and different load working environments.

[0062] The specific working principle of the adjustable drive shock absorbing mechanism provided by the present disclosure is:

[0063] The rotation of the motor drives the driving wheel to rotate synchronously through the adapter sleeve, driving the operation of the mechanism;

[0064] When the mechanism is running and encounters a bumpy road surface, the flange-type linear bushing moves up and down along the positioning shaft under the action of the shock-absorbing compression spring, so that the floating plate drives the motor and the drive wheel to move up and down. At the same time, the U-shaped plate acts as a lower limit, limiting the amplitude of the downward movement of the motor and the drive wheel driven by the floating plate.

[0065] When encountering different ground conditions, according to the load of the test trolley and the friction coefficient between the different ground conditions and the driving wheel of the driving mechanism, use a wrench to rotate the hexagon socket tip set screw set on the fixing plate to adjust the height of the limit plate to achieve the compression degree of the shock-absorbing spring.

[0066] Therefore, the specific force transmission process of an adjustable drive shock-absorbing mechanism provided by the present invention is: during operation, when encountering bumps, the driving wheel first receives the vibration and transmits it to the motor through the adapter sleeve; when the spring receives different compression forces, it will drive the flange-type linear sleeve and the floating plate to move up and down along the positioning shaft to reduce vibration and achieve the purpose of shock absorption.

[0069] The driven wheels are respectively arranged on the four corners of the trolley to provide support for the operation of the trolley.

[0070] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
