Description

Technical Field

[0001] The present invention relates to the field of automated conveying technology, and in particular to a high-precision, heavy-load, high-temperature, explosion-proof, double-station lifting RGV servo trolley. Background Art

[0002] RGV railcar is an automated transport equipment with a guidance system, similar to an automatic guided vehicle (AGV), but the difference is that the movement route of the RGV railcar is usually fixed. It can play an important role in long-distance, repetitive transportation tasks. RGV railcars usually have higher transportation efficiency and accuracy and are widely used in warehouses, production lines and other places. These vehicles usually have high maneuverability and transportation efficiency, and are particularly suitable for use in relatively closed or specific areas.

[0003] With the development of modern logistics and transportation industry, the safety and stability of cargo transportation has become the focus of attention of enterprises and consumers. In the process of cargo transportation, especially when using small transport vehicles (such as RGV rail cars) for cargo handling, a series of problems related to cargo stability are often faced.

[0004] When the RGV rail vehicle is turning, the vehicle speed and the inertia force of the turn will cause the cargo to slide, tilt or roll violently in the carriage, which may easily cause the cargo to move out of the fixed position and fall or be damaged. At the same time, at the moment the vehicle stops, due to the inertia effect, the cargo in the carriage will continue to move, causing the cargo to collide with the inner wall of the carriage or other objects, especially when the vehicle stops suddenly or in a short period of time, the inertial impact force of the cargo is greater, which may cause the cargo to be damaged, broken or fall out of the carriage.

[0005] Chinese patent CN117023023A discloses an RGV rail car automatic handling device, including: an RGV rail car, the top of the RGV rail car is provided with a plurality of first chutes equidistantly from left to right along the front-to-back direction; the front and rear ends of the first guide rod are respectively arranged on the front and rear sides of the inner cavity of the first chutes; there are a plurality of first springs, the plurality of first springs are respectively sleeved on the front and rear sides of the outer walls of the plurality of first guide rods, and the outer ends of the first springs are clamped on the outer side of the inner cavity of the first chutes. The device can prevent the inertia of the goods from falling during emergency braking, thereby improving the handling efficiency and safety of the goods. Secondly, the device can flexibly adjust the loading and unloading direction according to actual needs, thereby meeting the needs of complex logistics scenarios.

[0006] The above patent achieves the clamping of goods by means of clamping arms, but only two sides are clamped, and the other two sides are not protected, so the goods are easy to fall and be damaged. At the same time, when loading goods, the distance between the handling mechanism and the loading platform is far, making it difficult to load goods. Summary of the invention

[0025] S8: After the goods are unloaded, the second lifting rod is driven to descend, and the descent of the second lifting rod drives the loading platform to descend. At this time, the clamping member of the clamping assembly rotates inward; at the same time, the overlapping protection platform rotates toward the loading platform, forming a tightened state on both sides of the loading platform; the RGV rail car is driven to travel in the opposite direction along the track to receive the goods;

[0026] S9: Repeat steps S2 to S8.

[0027] Preferably, in S2 and S6, the specific steps of opening the clamping member of the clamping assembly outward are: when the loading platform rises, the first connecting rod is driven to rotate around the connecting column toward the outside of the baffle, and while rotating, the side of the first connecting rod located inside the baffle slides along the sliding sleeve toward the bottom of the loading platform; the second connecting rod fixedly connected to the first connecting rod rotates outward, driving the clamping member to move toward the outside of the baffle, forming a state in which the clamping member is opened outward;

[0028] The specific steps for rotating and moving the overlapping protection platform outward to form a horizontal loading channel with the loading platform are as follows: when the loading platform rises, one end of the L-shaped rod connected to the loading platform slides toward the outside of the loading platform through the slider, driving the L-shaped rod to rotate outward along the first mounting seat, and at the same time driving the end of the L-shaped rod connected to the frame to rotate toward the outside of the loading platform; through the hinge connection between the loading platform and the overlapping protection platform, under the rotation of the L-shaped rod, the loading platform and the overlapping protection platform form a horizontal loading channel.

[0030] The overlapping protection platform rotates and retracts toward the loading platform to form guardrails on both sides of the loading platform. The specific steps are as follows: when the loading platform descends, the end of the L-shaped rod connected to the loading platform slides toward the inner side of the loading platform through the slider, driving the L-shaped rod to rotate along the first mounting seat toward the inner side of the loading platform, and at the same time driving the end of the L-shaped rod connected to the frame to rotate toward the inner side of the loading platform; through the hinge of the loading platform and the overlapping protection platform, under the rotation of the L-shaped rod, the loading platform is horizontally set and the overlapping protection platform is vertically set, the angle between the loading platform and the overlapping protection platform forms a right angle, and the overlapping protection platforms on both sides of the loading platform form guardrails.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The clamping assembly provided in the present invention drives the first connecting rod to rotate around the connecting column toward the outside of the baffle plate when loading goods, and while rotating, the first connecting rod located on the side of the baffle plate slides along the sliding sleeve toward the bottom of the loading platform; the second connecting rod fixedly connected to the first connecting rod rotates outward, driving the clamping member to move toward the outside of the baffle plate, forming a state in which the clamping member is opened outward; after loading goods, the loading platform is lowered, driving the first connecting rod to rotate around the connecting column toward the inside of the baffle plate, and while rotating, the first connecting rod located on the baffle plate One side of the interior slides along the sliding sleeve toward the side of the loading platform; the second connecting rod fixedly connected to the first connecting rod rotates inwardly, driving the clamping member to move toward the baffle, forming a state in which the clamping member is clamped inwardly. After clamping, the clamping member abuts against the spring and the cargo, so that the cargo is in a clamped state, realizing the clamping function of the cargo and preventing it from falling off due to impact; at the same time, when the vehicle is traveling at a high speed or stops in an emergency, the compression or tension of the spring can give the cargo a buffering function, preventing fragile items from being broken or damaged due to the force of emergency braking.

[0033] (2) The overlapping protection platform and the adjusting rod provided in the present invention provide a channel for loading and unloading goods on the loading platform, and provide a function of preventing the goods on the vehicle from falling. Specifically, before loading or unloading goods, the loading platform is driven to rise, and the end of the L-shaped rod connected to the loading platform slides toward the outside of the loading platform through the slider, driving the L-shaped rod to rotate toward the outside of the loading platform along the first mounting seat, and at the same time driving the end of the L-shaped rod connected to the frame to rotate toward the outside of the loading platform. Further, the loading platform and the overlapping protection platform are hinged, and under the rotation of the L-shaped rod, the loading platform and the overlapping protection platform form a horizontal loading and unloading channel. When loading and unloading goods, the driving motor rotates to drive the roller to roll, and the rolling of the roller drives the goods on and off the vehicle, and then through the overlapping of the overlapping protection platform, it smoothly reaches the receiving platform and the loading platform, thereby solving the problem that it is difficult for goods to be loaded automatically.

[0034] After loading or unloading goods, the loading platform is driven to descend, and the end of the L-shaped rod connected to the loading platform slides toward the inner side of the loading platform through the slider, driving the L-shaped rod to rotate along the first mounting seat toward the inner side of the loading platform, and driving the end of the L-shaped rod connected to the overlapping protection platform to rotate toward one side of the loading platform. The loading platform and the overlapping protection platform are further hinged. Under the rotation of the L-shaped rod, the loading platform is horizontally set, and the overlapping protection platform is vertically set. The angle between the loading platform and the overlapping protection platform forms a right angle, and the overlapping protection platforms on both sides of the loading platform form a guardrail; after loading goods, it has the function of serving as a guardrail to protect the goods; when no goods are loaded, the overlapping protection platform is vertically set, which can reduce the body width of the RGV servo car, and avoids the problem of damage caused by collision between the overlapping protection platform and objects on both sides during driving.

[0035] (3) The RGV servo trolley of the present invention realizes the clamping or loosening of the cargo by the clamping assembly through the lifting and lowering of the second lifting rod, and the overlapping protective platform serves as a loading and unloading passage when loading and unloading cargo, and serves as a protective fence after loading and unloading cargo. The operation is simple, reliable and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The preferred embodiments of the present invention are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0046] Example 1

[0047] like Figures 1 to 8 As shown, a high-precision, heavy-load, high-temperature, explosion-proof, double-station lifting RGV servo trolley comprises an RGV rail car 100, wherein the upper part of the RGV rail car 100 is fixedly connected with two front and rear bases 300 through a first lifting rod 200, and baffles 310 are provided at both ends of the base 300; a loading platform 400 is installed in the base 300, and a plurality of second lifting rods 700 are connected between the loading platform 400 and the base 300; overlapping protection platforms 500 are hinged on both sides of the loading platform 400, and adjusting rods 800 are connected between the two ends of the loading platform 400 and the two sides of the overlapping protection platforms 500 on both sides; clamping assemblies 600 are installed at both ends of the loading platform 400 through baffles 310;

[0048] The RGV rail vehicle 100 is mainly used for traveling on the track. Specifically, the device is also provided with a control system for vehicle travel. The control system manages and directs the movement, stop, turn and other operations of the trolley. The specific control system may be a PLC control system. The control system is responsible for receiving instructions from the upper system or manual operation and dispatching the actions of the trolley. These are all prior art and will not be described in detail here. The control system also controls the lifting and lowering of the first lifting rod 200 and the second lifting rod 700 and the operation of the motor 450. The first lifting rod 200 and the second lifting rod 700 may be retractable electrical cylinders or hydraulic cylinders, which are not limited here. The control system may separately or simultaneously control the lifting and lowering of the loading platforms 400 on the two bases 300. The motor 450 is a forward and reverse synchronous motor. The base 300 is used to install the loading platform 400 and overlap the protective platform 500. The second lifting rod 700 is used to support and lift the loading platform 400.

[0049] The loading platform 400 includes a frame 410, and a plurality of rollers 420 are horizontally rotatably installed between the two side walls of the frame 410. Sprockets 430 are installed at both ends of the rollers 420, and a chain 440 is transmission-connected between the plurality of sprockets 430. A motor 450 is fixed to one side of the frame 410, and the output shaft of the motor 450 passes through the frame 410 and is fixedly connected to the end of one of the rollers 420.

[0050] The loading platform 400 can realize the rolling of the roller 420 by driving the motor 450 to rotate. At the same time, the rotation of the roller 420 drives the chain 440 and the multiple sprockets 430 to transmit the multiple rollers 420 to roll at the same time, driving the goods to get on or off the vehicle.

[0051] In this embodiment, the adjustment rod 800 includes an L-shaped rod 810, a hole 811 is opened at the corner of the L-shaped rod 810, and the first mounting seat 320 is installed at the four corners of the base 300. The L-shaped rod 810 is hinged to the first mounting seat 320 through the hole 811; one end of the L-shaped rod 810 is hinged to the corresponding side of the bottom of the overlapping protection platform 500; the other end of the L-shaped rod 810 is hinged to a slider 820, and sliding grooves 411 are opened on both sides of the bottom of the frame 410, and the sliding end of the slider 820 is slidably connected in the sliding groove 411.

[0052] The adjusting rod 800 is used to connect the loading platform 400 and the overlapping protection platform 500, so that when the loading platform 400 rises or falls, a linkage effect can be generated between the overlapping protection platform 500;

[0053] When the loading platform 400 rises, a loading channel or a unloading channel is formed. When the channel is formed, the overlapping blocks 530 arranged on the outer side of the overlapping protection platform 500 are overlapped on the receiving platform and the delivery platform; specifically, when loading goods, the delivery platform pushes the goods and the rollers of the loading platform 400 roll, so that the goods can be smoothly loaded onto the vehicle through the overlapping protection platform 500. When unloading goods, the goods are delivered by receiving the goods on the receiving platform and rolling the rollers of the loading platform 400, so that the goods can be smoothly unloaded from the vehicle through the overlapping protection platform 500; through the setting of the overlapping protection platform 500, it can withstand greater gravity when loading goods, transport heavier goods, and realize the heavy-load function.

[0054] It should be noted that when delivering goods, the angle between the loading platform 400 and the overlapping protection platform 500 can be adjusted. For example, when receiving goods, the angle between the two can be made slightly less than 180°, and when unloading goods, the angle between the two can be made slightly greater than 180°, so that when the goods pass through the overlapping protection platform 500, it is easier to pass;

[0055] When the loading platform 400 descends, the loading platform 400 and the overlapping protection platform 500 form a right angle, and the overlapping protection platforms 500 on both sides of the loading platform 400 form a guardrail; after loading the goods, it serves as a guardrail to protect the goods; when not loaded with goods, the overlapping protection platform 500 is vertically arranged to reduce the body width of the RGV servo vehicle, thereby avoiding the problem of damage caused by the overlapping protection platform 500 colliding with objects on both sides during driving.

[0056] In this embodiment, the clamping assembly 600 includes a sliding sleeve 610, and second mounting seats 412 are provided at both ends of the frame 410. The mounting end of the sliding sleeve 610 is rotatably connected to the second mounting seat 412. A first connecting rod 620 is slidably connected inside the sliding sleeve 610. A through hole 621 is provided in the middle of the first connecting rod 620. The middle of the first connecting rod 620 is rotatably connected to a connecting column 311 set on the baffle 310 through the through hole 621. The end of the first connecting rod 620 located on the outside of the baffle 310 is fixedly connected to the second connecting rod 630, and the end of the first connecting rod 620 located on the inside of the baffle 310 is fixedly connected to a limiting ball 650, and the other end of the second connecting rod 630 is connected to a clamping member 640.

[0057] The clamping assembly 600 is mainly used to clamp the cargo to prevent the cargo from being damaged due to the inertia generated when the cargo is parked or driving, and to protect the loaded cargo, especially the explosion-proof protection of fragile items;

[0058] The sliding sleeve 610 is rotatably connected to the side of the frame 410, so that the first connecting rod 620 can rotate smoothly and slide in the sliding sleeve 610 when the loading platform 400 rises or falls; when the loading platform 400 rises, the end of the first connecting rod 620 located on the inner side of the baffle 310 rotates upward, and the end of the first connecting rod 620 located on the outer side of the baffle 310 rotates downward, so that the clamping member 640 moves toward the outside of the baffle 310. At this time, it is necessary to load or unload goods, and the opening of the clamping member 640 facilitates the loading and unloading of goods. After loading is completed, the loading platform 400 descends. At this time, the end of the first connecting rod 620 located on the inner side of the baffle 310 rotates downward, and the end of the first connecting rod 620 located on the outer side of the baffle 310 rotates upward, so that the clamping member 640 moves toward the inner side of the baffle 310, clamps the goods on the loading platform 400, and performs limit control.

[0059] It should be noted that the limiting ball 650 limits the sliding connection of one end of the first connecting rod 620 located inside the baffle plate in the sliding sleeve 610, and the rotation of the first connecting rod 620 located on the side inside the baffle plate 310 will not affect the lifting and lowering of the second lifting rod 700, and the two are staggered; at the same time, the sliding of the L-shaped rod 810 in the slide groove 411 will not affect the lifting and lowering of the second lifting rod 700; the clamping assemblies 600 at both ends of the two bases 300 are also staggered and will not cause interference.

[0060] In this embodiment, a convex circular groove 631 is provided inside one end of the second connecting rod 630 located at the clamping member 640, and a spring 632 is installed at the bottom of the convex circular groove 631; the clamping member 640 includes a clamping block 642 and a connecting rod 641, and the connecting rod 641 is slidably connected in the convex circular groove 631, and the end of the connecting rod 641 located in the convex circular groove 631 abuts against the spring 632, and the end of the connecting rod 641 located outside the convex circular groove 631 is fixedly connected to the clamping block 642.

[0061] After the goods are clamped, when the goods are delivered, the inertial force generated when the trolley stops causes the clamping block 642 to abut against the spring 632. At the same time, the compression force of the spring 632 has a buffering function, thereby preventing fragile goods from being broken or damaged.

[0062] In this embodiment, the overlapping protection platform 500 includes a frame 510, and a plurality of rollers 520 are rotatably connected between the two side walls of the frame 510; one end of the frame 510 is hinged to one side of the loading platform 400, and a overlapping block 530 is fixed to the other end of the frame 510.

[0063] In this embodiment, the second connecting rod 630 is an L-shaped connecting rod.

[0064] In this embodiment, a plurality of the second lifting rods 700 are evenly arranged at the bottom of the frame 410; and the motor 450 is an explosion-proof motor.

[0065] A plurality of second lifting rods 700 are evenly arranged at the bottom of the frame 410, and can accurately control the lifting and lowering of the loading platform 400. The motor 450 is an explosion-proof motor, and can prevent explosion caused by sparks generated by external high temperature or electrical failure.

[0066] Example 2

[0068] S1: driving the first lifting rod 200 to adjust the height of the base 300, and adjusting the height to facilitate loading and unloading of goods;

[0069] S2: driving the second lifting rod 700, the second lifting rod 700 rises and drives the loading platform 400 to rise. When the loading platform 400 rises, the clamping member 640 of the clamping assembly 600 moves to the outside of the baffle 310, and the overlapping protection platform 500 rotates and moves outward to the outside of the loading platform 400, and forms a horizontal loading channel with the loading platform 400;

[0070] S3: driving the roller shaft 420 of the loading platform 400 to rotate in the upward direction, the goods are delivered to the loading platform 400 through the delivery platform, and under the push of the delivery platform and the rolling of the roller shaft 420 of the loading platform 400, the goods are delivered to the loading platform 400 through the overlapping protection platform 500;

[0071] S4: After the cargo arrives at the loading platform 400, the second lifting rod 700 is driven to descend, and the descent of the second lifting rod 700 drives the loading platform 400 to descend. At this time, the clamping member 640 of the clamping assembly 600 rotates inward to clamp the cargo; at the same time, the overlapping protection platform 500 rotates and retracts toward the loading platform 400 to form a protection fence on both sides of the loading platform 400;
