Description

Technical Field

[0002] The limit device of a logistics shuttle is a safety device used to control the travel range of the shuttle within the track or work area. The limit device mainly prevents the shuttle from exceeding the predetermined range of motion to ensure the safe operation of the equipment. Usually, limit devices such as buffers or baffles are set at both ends of the shuttle. When the shuttle reaches the limit position, the limit device will prevent it from moving further to avoid collision or damage caused by exceeding the travel range. Due to the inaccurate positioning of the limit device in the related art, position deviation may occur during the installation process, causing the shuttle to stop in an unexpected range, thereby affecting normal work efficiency.

The return spring allows the buffer mechanism to quickly return to its original position after impact, maintaining continuous system operation, eliminating frequent manual adjustments, and improving work efficiency. By adjusting the stopper nut, the tension of the buffer and return springs can be varied, thereby adjusting the buffering force and return speed to suit different logistics shuttles and load requirements. The two-level protection of the buffer spring and return spring can absorb impacts of varying intensities, providing a gentler cushioning effect and reducing equipment wear and the risk of failure. The combination of the buffer block and buffer mechanism significantly reduces noise at the shuttle's endpoint, improving work comfort. The buffer mechanism acts as a physical barrier between the stopper and the fixed base, effectively preventing the shuttle from traveling beyond its intended range, thereby protecting the safety of the entire system.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] A limiting device for a logistics shuttle vehicle, such as Figure 1As shown, it includes a limit baffle 501, a fixed base 401, an adjustable detection mechanism, two side support structures, two mounting structures 402 and two buffer mechanisms; the limit baffle 501 is connected to the fixed base 401 through two buffer mechanisms, and the two buffer mechanisms are symmetrically arranged on the fixed base 401; the two side support structures are symmetrically arranged at the left and right ends of the fixed base 401, and the left and right ends of the adjustable detection mechanism are detachably connected to each side support structure, and the adjustable detection mechanism is used to detect the position of the logistics shuttle vehicle; the two mounting structures 402 are symmetrically arranged at the left and right ends of the upper end surface of the fixed base 401, and the mounting structures 402 are used to connect to the guide rails. A thickened pad 502 is provided on the end surface of the limit baffle 501 facing the fixed base 401. The mounting structure 402 includes an L-shaped mounting plate, the top of the L-shaped mounting plate is provided with a strip hole for installation and positioning, and the bottom of the L-shaped mounting plate is welded to the fixed base 401.

[0032] like Figure 2 As shown, the buffer mechanism includes a guide slide 601, a buffer spring 603, a return spring 602, and a limit nut. One end of the guide slide 601 is threadedly connected to the limit baffle 501, and the other end of the guide slide 601 is threadedly connected to the limit nut. The buffer spring 603 and the return spring 602 are both arranged on the guide slide 601. The guide slide 601 passes through the fixed base 401. The buffer spring 603 is arranged on the inside of the fixed base 401, and the return spring 602 is arranged on the outside of the fixed base 401. The limit nut is used to compress the return spring 602. It also includes a buffer pad, which is arranged on the inner end surface of the fixed base 401. The buffer mechanism, through the combination of the guide slide 601, the buffer spring 603, and the return spring 602, effectively reduces the impact force when the shuttle car contacts the limit baffle 501, protects the shuttle car and the limit device, and extends the service life of the equipment. The guide slide 601 and limit nut ensure the stability of the buffer mechanism, allowing it to maintain proper function even under repeated impacts, ensuring smooth and reliable limiting action. The presence of a return spring 602 allows the buffer mechanism to quickly return to its original position after an impact, maintaining continuous system operation, eliminating frequent manual adjustments, and improving work efficiency. By adjusting the limit nut, the compression of the buffer spring 603 and return spring 602 can be varied, thereby adjusting the buffering force and reset speed to suit different logistics shuttle vehicles and load requirements. The buffer spring 603 and return spring 602 provide two levels of protection, absorbing impacts of varying intensities and providing a gentler cushioning effect, reducing equipment wear and the risk of failure. The combination of the buffer block and the buffer mechanism significantly reduces noise at the shuttle's endpoint, improving work comfort. The buffer mechanism acts as a physical barrier between the limit baffle 501 and the fixed base 401, effectively preventing the shuttle from operating beyond its intended range, thereby protecting the safety of the entire system.

The left and right ends of the adjustment base 201 are connected to a side support structure through a locking device. An arched groove is provided in the middle of the adjustment base 201, and the two photoelectric sensors 202 are symmetrically arranged in the arched groove. The adjustment base 201 can accurately adjust the detection position, and in conjunction with the photoelectric sensor 202, it can more accurately detect the current position of the logistics shuttle vehicle and prevent operational errors caused by position deviation. The locking device ensures that the adjusted detection mechanism is stable in a fixed position and is not easily displaced by external force or vibration, thereby ensuring the reliability of the detection results. The adjustable detection mechanism can adapt to logistics shuttle vehicles of different sizes and types, and the position of the photoelectric sensor 202 can be adjusted as needed, which increases the versatility of the equipment. The design of the adjustment and locking device makes maintenance and replacement of sensors simpler and more convenient, reduces downtime, and improves maintenance efficiency.

[0034] The side support structure includes a first reinforcing rib, a second reinforcing rib, a support rod 101, a connecting plate 103 and a guide plate 102. One end of the support rod 101 is welded to the guide plate 102, and the other end of the support rod 101 is welded to the fixed base 401.

The guide plate 102 is provided with a guide groove, and the guide groove is connected to the adjustment base 201 through a locking device. A connecting plate 103 is set at the end of the guide plate 102 away from the support rod 101.

[0035] like Figure 4 As shown, the locking device includes a locking screw 301, a locking nut 302, an annular pressure plate 303 and an anti-slip gasket. The locking screw 301 passes through the locking nut 302, the annular pressure plate 303, the anti-slip gasket, the guide groove and the end of the adjustment base 201 in sequence. The ends of the locking nut 302 and the adjustment base 201 are both threadedly matched with the locking screw 301.
