Description

Technical Field

[0001] This utility model relates to a track plate assembly interference detection device, belonging to the technical field of track plate detection devices. Background Technology

[0002] Track shoes are crucial components of the undercarriage running gear of construction machinery and mining equipment, such as large electric loaders, excavators, bulldozers, and mining transport vehicles. Track shoes are typically manufactured from high-strength and impact-toughness alloy castings or forgings to ensure they can withstand the pressure of heavy equipment and harsh working conditions. Pins connect multiple track shoes together to form tracks; the assembly between the pins and the track hinge pin holes must be smooth and interference-free.

[0003] A search revealed that existing track plate inspection devices primarily focus on testing the strength, dimensional parameters (e.g., pin hole spacing), and tooth profile of individual track plate workpieces. No devices were found specifically designed to detect interference between multiple assembled track plates. Currently, there is a lack of effective technical means to detect interference between assembled track plates in advance. Interference is typically only detected during actual operation after formal installation, and the specific location of interference is difficult to pinpoint, impacting overall production progress and assembly efficiency. Utility Model Content

[0004] The present invention aims to provide a track plate assembly interference detection device, which can effectively detect in advance whether there is interference in multiple sets of track plates after assembly, thereby improving assembly efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a track plate assembly interference detection device includes a frame, a drive wheel, a safety rope, and a guide wheel. A track plate placement platform is provided on the frame. The drive wheel is rotatably located at the right end of the frame, and the guide wheel is rotatably located at the left end of the frame. The axes of the drive wheel and the guide wheel are both horizontally arranged along the front-back direction. The drive wheel is equipped with a drive mechanism for driving its rotation. A drive gear is coaxially fixed on the drive wheel. The drive gear is used to cooperate with the track plate assembly to form a gear and rack transmission structure. A rope groove is provided on the outer circumference of the drive wheel. One end of the safety rope is fixedly connected to the rope groove and wound in the rope groove. The other end is used to connect to the track plate assembly after passing over the guide wheel. When the drive gear drives the track plate assembly to move from left to right on the track plate placement platform, the safety rope in the rope groove is in the unwinding state.

[0006] A further preferred embodiment is that the drive mechanism of the drive wheel includes a motor, and a torque sensor is mounted on the output shaft of the motor.

[0007] A further preferred embodiment is that the output shaft of the motor is connected to the central shaft of the drive wheel via a coupling, and the output shaft of the motor and the central shaft of the drive wheel are arranged coaxially.

[0008] A further preferred embodiment is that one end of the safety rope is fixedly connected to a safety chain for connecting the track plate assembly, and the end of the safety chain away from the safety rope is provided with a connecting hook.

[0009] A further preferred embodiment is that a connector is fixedly installed on the frame, and the connecting hook forms a detachable connection with the connector.

[0010] A further preferred embodiment is that the safety chain includes multiple safety chain units connected end to end, with a detachable connection between adjacent safety chain units.

[0011] A further preferred embodiment is that two adjacent safety chain units are connected by a threaded rod and a threaded sleeve.

[0012] A further preferred option is that adjacent safety chain units are connected by hooks.

[0013] A further preferred embodiment is that when the drive gear and track plate assembly form a gear and rack transmission structure, the guide wheel is located on the symmetrical center plane of the track plate assembly in the front-rear direction; the guide groove of the guide wheel is V-shaped or U-shaped.

[0014] A further preferred option is to have a tensioning wheel on the frame for controlling the tension of the safety rope.

[0015] In the implementation of the above scheme, the track plate assembly to be tested is laid flat on the track plate placement platform of the frame. One end is connected to a safety rope to prevent it from falling during testing, while the other end is free. The end of the track plate assembly away from the safety rope is connected to the drive wheel via a gear and rack transmission structure. During testing, the drive wheel rotates, causing the track plate assembly to move. When the first track plate detaches from the drive wheel without any abnormal noise or jamming, the first track plate is considered qualified. Subsequent track plate assemblies are then tested continuously; if they detach from the drive wheel without any abnormal noise or jamming, the corresponding track plate is considered qualified. If abnormal noise or jamming occurs during testing, it is necessary to identify which track plate is faulty and address the issue before testing can continue.

[0016] In the preferred embodiment, the drive wheel is driven by a motor, and a torque sensor is installed on the output shaft of the motor. During the specific testing process, the corresponding torque value can also be monitored simultaneously. If the torque value does not exceed the specified value, the corresponding track plate workpiece is qualified; if the torque value exceeds the specified value, it is necessary to detect which track plate workpiece has a problem and take corrective action before continuing the testing.

[0017] The beneficial effects of this invention are as follows: After multiple track plate workpieces are properly assembled, a track plate assembly to be inspected is formed. This invention can simulate actual application scenarios to detect interference and fit issues in the track plate assembly, quickly identifying problematic parts. It can be performed by motor drive or manually. This invention also includes a safety rope to prevent damage from falling track plate assemblies and to prevent injuries during the inspection process, ensuring speed, accuracy, safety, and convenience. This invention solves the previous problems of delayed problem detection after track plate assembly and the difficulty of disassembling assembled track plate assemblies on the production assembly site, thus improving production assembly efficiency.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 4 This utility model includes a frame 1, a drive wheel 2, a safety rope 5, and a guide wheel 6. A track plate placement platform 101 is provided on the frame 1. The track plate placement platform 101 only needs to allow the track plate assembly 8 to be inspected to be laid flat on its top surface. To ensure the frame 1 has a simple and reliable structure, in the preferred embodiment shown in the attached drawings, the track plate placement platform 101 consists of two horizontal beams arranged side by side. The length direction of each horizontal beam is horizontally arranged along the left-right direction, and the spacing between the two horizontal beams can be reasonably determined according to the width of the track plate assembly 8.

[0025] The driving wheel 2 is rotatably arranged at the right end of the frame 1, and the guiding wheel 6 is rotatably arranged at the left end of the frame 1. The axes of the driving wheel 2 and the guiding wheel 6 are both horizontally arranged along the front-back direction. The driving wheel 2 is equipped with a driving mechanism for driving its rotation; coaxially and fixedly arranged on the driving wheel 2 is a driving gear 201, which is used to cooperate with the crawler plate assembly 8 to form a gear-rack transmission structure; the distribution mode of the driving gear 201 can be correspondingly designed according to the crawler plate assembly 8 to be detected. It can be to arrange a driving gear 201 at the middle position in the axial direction of the driving wheel 2, or to arrange a driving gear 201 at both ends in the axial direction of the driving wheel 2 respectively, so as to meet the interference detection requirements of different types of crawler plates.

[0026] A rope winding groove 202 is arranged on the outer peripheral surface of the driving wheel 2. One end of the safety rope 5 is fixedly connected to the rope winding groove 202 and wound in the rope winding groove 202, and the other end is used to connect the crawler plate assembly 8 after passing around the guiding wheel 6 (the safety rope 5 can be directly connected to the crawler plate assembly 8 or indirectly connected to the crawler plate assembly 8 through other connecting members). The safety rope 5 can be a steel rope or a lifting rope with sufficient strength, etc.; when the driving gear 201 drives the crawler plate assembly 8 to move from left to right on the crawler plate placing platform 101, the safety rope 5 in the rope winding groove 202 is in a state of being unreeled correspondingly. That is, when the crawler plate assembly 8 is normally detected, the safety rope 5 connected to the left end of the crawler plate assembly 8 can move synchronously.

[0027] In specific implementation, the crawler plate assembly 8 to be detected is laid flat on the crawler plate placing platform 101 of the frame, one end is connected to the safety rope 5 to prevent falling during detection, and the other end is in a free state; the end of the crawler plate assembly 8 away from the safety rope 5 is connected to the driving wheel 2 in the form of a gear-rack transmission structure. Refer to Figure 2 and Figure 3 , during detection, the driving wheel 2 rotates to drive the crawler plate assembly 8 to move. When the first crawler plate workpiece of the crawler plate assembly 8 breaks away from the driving wheel 2 without abnormal noise and jamming, the first crawler plate workpiece is qualified. The subsequent other crawler plate workpieces are continuously detected. Similarly, if they break away from the driving wheel 2 without abnormal noise and jamming, the corresponding crawler plate workpieces are qualified. If there are abnormal noise and jamming during the detection process, it is necessary to detect which crawler plate workpiece has problems and dispose of them, and then continue the detection after passing the qualification.

[0028] The drive mechanism of the drive wheel 2 can be any manual or electric drive mechanism. For ease of implementation, it preferably includes a motor 4, and a torque sensor 3 is installed on the output shaft of the motor 4. During the specific testing process, the corresponding torque value can also be monitored simultaneously. If the torque value does not exceed the specified value, the corresponding track plate workpiece is qualified; if the torque value exceeds the specified value, it is necessary to detect which track plate workpiece has a problem and deal with it. Only after it is qualified can the testing continue. In this scheme, the motor can also be set to an unloaded mode to achieve manual testing. The motor 4 is preferably an adjustable speed motor to prevent accidents caused by excessive speed, and it is also preferably equipped with a torque overload protection device. The motor 4 can be a servo motor, a frequency converter motor, or a general motor with a reducer, etc. The base of the motor 4 is fixedly connected to the support plate of the frame 1 by bolts.

[0029] To ensure a simple, reliable structure that is easy to manufacture and assemble, the output shaft of motor 4 is connected to the central shaft of drive wheel 2 via a coupling, and the output shaft of motor 4 and the central shaft of drive wheel 2 are coaxially arranged. In some alternative embodiments, the output shaft of motor 4 and the central shaft of drive wheel 2 may also be the same long shaft. Regardless of which structural form is adopted, it is necessary to ensure that the coaxiality meets the design requirements to prevent runout and wobbling.

[0030] The safety rope 5 can be directly connected to the track plate assembly 8, or indirectly connected to the track plate assembly 8 through other connecting components. For ease of assembly, a safety chain 7 for connecting the track plate assembly 8 is preferably fixedly connected to one end of the safety rope 5. A connecting hook 701 is provided at the end of the safety chain 7 away from the safety rope 5. During testing, the connecting hook 701 is used to directly connect to the track plate assembly 8. In a further preferred embodiment, a connector 102 is fixedly provided on the frame 1, and the connecting hook 701 and the connector 102 form a detachable connection. When the device is not working, the connector 102 serves as a temporary connection fixing point for the safety chain 7. The connector 102 can be set at any reasonable position on the frame 1, specifically it can be a connecting support rod, a connecting ring, or other structural forms. In the preferred embodiment shown in the attached figure, the connector 102 adopts the structure of a connecting support rod and is fixedly set on the inner wall of one of the horizontal beams.

[0031] To further facilitate implementation, the safety chain 7 has an adjustable length function. The safety chain 7 comprises multiple safety chain units connected end-to-end, with adjacent safety chain units forming a detachable connection. There are several specific detachable connection methods. For example, adjacent safety chain units can be connected via a threaded rod and a threaded sleeve, meaning one safety chain unit has a threaded rod and the other has a threaded sleeve; or adjacent safety chain units can be connected via hooks. This allows for quick and easy adjustment of the safety chain 7's length to adapt to different track plate assemblies 8.

[0032] During specific testing, the guide wheel 6 is preferably located at the center of symmetry of the track plate assembly 8, serving to adjust for sway; that is, when the drive gear 201 and the track plate assembly 8 form a rack and pinion transmission structure, the guide wheel 6 is located on the center plane of symmetry in the front-rear direction of the track plate assembly 8. The guide groove of the guide wheel 6 is preferably V-shaped or U-shaped. The guide groove of the guide wheel 6 refers to the annular groove used for guiding the safety rope 5. There can be one or more guide wheels 6. In addition, depending on the actual situation, a tensioning wheel for controlling the tension of the safety rope 5 can also be provided on the frame 1.
