Description

Technical Field

[0001] This utility model relates to the field of trolley track technology, and in particular to a trolley track with shock absorption function. Background Technology

[0002] In the application scenarios of stamping equipment, the trolley track plays a key role. Traditional tracks are fixed with screws and washers. During the movement of the trolley and the stamping process, they are subjected to huge impact forces, making it difficult to avoid vibration problems. Long-term vibration will reduce the preload of the screws on the track, and may even cause the screws to break or the track to slip off, which seriously affects the parallelism and overall stability of the track, and thus has an adverse effect on the processing accuracy and service life of the stamping equipment.

[0003] Chinese utility model patent CN214005272U discloses a vibration-damping track for industrial robots, including a track body, a pre-embedded steel plate, a rubber pad, and a vibration-damping device. The track body has feet on both sides; the pre-embedded steel plate is laid at the lower end of the track body; the rubber pad is located between the pre-embedded steel plate and the feet and connected by the vibration-damping device; the vibration-damping device includes a screw and a support sleeve, a pressure cap, and a spring coaxially fitted with the screw; the pressure cap has a cavity, and the spring is compressed within the cavity. Although this invention provides a certain vibration-damping effect through the combination of rubber pads and springs on both sides of the track, the vibration generated when the trolley performs stamping work on the track cannot be effectively absorbed and will still seriously affect the track. Furthermore, this invention lacks real-time status monitoring and early warning functions. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a trolley track with shock absorption function, which can not only effectively absorb the vibration generated by the trolley at each stage, but also has a vibration monitoring function to deal with overload conditions in a timely manner.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a trolley track with shock absorption function, including a track and a mounting base. The two ends of the track are connected to the mounting base through a first shock absorption mechanism. A shock absorption pad is installed between the track and the mounting base. A third shock absorption mechanism is provided on the track. The third shock absorption mechanism is used to absorb the vibration generated when the trolley works on the track. At least one vibration sensor is fixed on the track. The vibration sensor is used to detect the vibration parameters of the track.

[0006] Furthermore, the first damping mechanism includes a spring, a washer, and a set screw. One end of the spring abuts against the washer, and the other end abuts against the track. The set screw passes through the washer, spring, track, and damping pad in sequence and is then fixed in the mounting base.

[0007] Furthermore, the third damping mechanism includes a hydraulic damping unit and a fixed seat embedded in the mounting base. The hydraulic damping unit is fixed in the fixed seat. The hydraulic damping unit includes a hydraulic cylinder and a gasket. The hydraulic cylinder is fixed to the fixed seat, and the gasket is fixed to the upper end of the main shaft of the hydraulic cylinder and abuts against the surface of the track.

[0008] Furthermore, two vibration sensors are fixed to the bottom of the track. The two vibration sensors are respectively installed on the inner side of the mounting bases at both ends of the track. The vibration sensors are used to detect vibration parameters when the trolley enters or leaves the track.

[0009] Furthermore, a limiting block is fixed on the mounting base, and the limiting block is used to position the installation position of the track.

[0010] Furthermore, the track is an I-beam type track.

[0011] Compared with the prior art, the advantages of this utility model are that it adds a hydraulic damping unit to absorb the vibration generated when the trolley is stamping on the track. The hydraulic damping unit, together with the first damping mechanism and the damping pad, forms a multi-level damping mechanism, which can more comprehensively and efficiently reduce the vibration generated by the trolley on the track. In addition, the vibration sensor fixed on the track realizes real-time monitoring of the vibration parameters of the trolley when it is running on the track, effectively preventing potential accidents such as track deformation, loosening and breakage of connecting parts, and improving operational safety.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-3As shown, a trolley track with shock absorption function includes a track 1 and a mounting base 2. Both ends of the track 1 are connected to the mounting base 2 via a first shock absorption mechanism 3. A shock absorption pad 4 is installed between the mounting base 2 and the track 1. The first shock absorption mechanism 3 includes a spring 31, a washer 32, and a set screw 33. One end of the spring 31 abuts against the washer 32, and the other end abuts against the track 1. The set screw 33 passes through the washer 32, spring 31, track 1, and shock absorption pad 4 in sequence and is then fixed to the mounting base 2. A limit block 21 is fixed on the mounting base 2. The limit block 21 is used to position the installation position of the track 1, ensuring the accuracy and parallelism of the track 1 installation. The track 1 is provided with a third shock absorption mechanism 5, which is used to absorb the vibration generated when the trolley 8 works on the track 1. The third shock absorption mechanism 5 includes a hydraulic shock absorption unit and a fixed seat 51 pre-embedded in the mounting base 7. The vibration damping unit is fixed inside the fixed base 51. The hydraulic damping unit includes a hydraulic cylinder 52 and a pad 53. The hydraulic cylinder 52 is fixed to the fixed base 51, and the pad 53 is fixed to the upper end of the main shaft 521 of the hydraulic cylinder 52 and abuts against the surface of the track 1. The third damping mechanism 5, together with the first damping mechanism 3 and the damping pad 4, forms a multi-stage damping mechanism, which can more comprehensively and efficiently reduce the vibration of the trolley 8 on the track 1. Two vibration sensors 6 are fixed at the bottom of the track 1. The two vibration sensors 6 are respectively installed on the inner side of the mounting base 2 at both ends of the track 1. The vibration sensors 6 are used to detect the vibration parameters when the trolley 8 enters or leaves the track 1, so that the track 1 has real-time vibration monitoring and overload warning functions, and the safety and maintainability are greatly improved. In this embodiment, the track 1 adopts an I-beam steel track, which saves costs while ensuring structural strength and load-bearing capacity.

[0017] The vibration sensor 6 and hydraulic cylinder 52 used in this embodiment are both existing technologies and will not be described in detail here.
