Description

Technical Field

[0001] The utility model relates to the technical field of RGV trolleys, in particular to a high-speed RGV trolley with limited position and anti-slip function. Background Art

[0002] RGV trolley is a rail-guided vehicle, which is often used in warehouses where goods are concentrated. It transports goods in the warehouse by rail. It has the advantages of full automation and fast transportation speed. Usually, the operation mode of RGV trolley adopts multiple vehicles on the same track, so it is easy for multiple vehicles to collide. In order to protect the RGV trolley and the goods transported by the trolley, the RGV trolley multi-vehicle avoidance device is developed accordingly.

[0003] Announcement No. CN219362284U discloses a multi-vehicle avoidance device for RGV trolleys. The device achieves the purpose of automatically braking the RGV trolley in the event of a collision through the cooperation between wheels, detection rods, toggle blocks, sliding resistors, coils, deceleration blocks and magnetic blocks. At the same time, the greater the collision force, the greater the braking force of the deceleration block on the wheel, that is, the greater the collision force, the shorter the braking time of the RGV trolley, which solves the problem that the traditional device cannot perform emergency braking on the RGV trolley after a collision, making the RGV trolley easily run out of the track during the collision, causing greater damage. However, the patent still has the following problems in actual use:

[0004] The device achieves the purpose of automatically braking the RGV trolley in the event of a collision through the cooperation between the wheels, detection rods, toggle blocks, sliding resistors, coils, speed reduction blocks and magnetic blocks, thereby preventing the RGV trolley from easily running off the track during a collision and causing greater damage. Although the device can protect both ends of the RGV vehicle, it cannot protect both sides of the RGV. As a result, when the RGV trolley is hit on the side, it may cause uneven force on the trolley and generate lateral or tilting torque, thereby increasing the risk of derailment and bringing danger to the staff when using it.

[0005] A high-speed RGV trolley with limited position and anti-slipping function is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a high-speed RGV trolley with limited position and anti-slipping function, so as to solve the problem proposed in the above-mentioned background technology that the RGV trolley can be automatically braked in the event of a collision through the cooperation between wheels, detection rods, toggle blocks, sliding resistors, coils, deceleration blocks and magnetic blocks, thereby avoiding the problem that the RGV trolley is easy to run off the track during the collision and cause greater damage. Although the device can protect both ends of the RGV vehicle, it cannot protect both sides of the RGV, and thus when the side of the RGV trolley is collided, it may cause uneven force on the trolley, generate lateral or tilting torque, thereby increasing the risk of derailment and bringing danger to the staff when using it.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed RGV trolley with limited position and anti-slipping, comprising a base, a vehicle body is installed on the top of the base, and buffer mechanisms are symmetrically arranged on the outer sides of both ends of the vehicle body, and two sets of wheels are symmetrically arranged on the bottom of the base; protective mechanisms are symmetrically arranged on both sides of the vehicle body, and mounting components are arranged inside the protective mechanisms;

[0008] Among them, the protection mechanism includes a mounting frame, and the mounting frames are symmetrically arranged on both sides of the vehicle body, and protection plates are symmetrically arranged on both sides of the vehicle body, and connecting frames are symmetrically installed at both ends of the mounting frame, and support rods are symmetrically installed inside the mounting frame, and the outer side of the support rod is slidably connected to the sliding frame, and the bottom end of the sliding frame passes through the mounting frame for sliding connection, and the outer side of the support rod is sleeved with a first telescopic spring, and slide plates are symmetrically slidably connected inside the two ends of the mounting frame, and connecting rods are symmetrically rotationally connected on both sides of the sliding frame, and one end of the connecting rod is rotationally connected to the slide, and a push plate is installed at one end of the slide, and a retraction rod is symmetrically installed between the push plate and the inner side of the connecting frame, and the outer side of the retraction rod is sleeved with a second telescopic spring.

[0009] Preferably, the mounting assembly includes mounting plates symmetrically and slidably connected to the inside of both sides of the vehicle body, and fixing boxes are symmetrically installed on both sides of the vehicle body, and mounting grooves are opened inside the fixing boxes, and screws are rotatably connected between the mounting grooves and the fixing boxes, and push blocks are threadedly connected to the outer sides of the screws, and a sliding groove is opened inside one side of the fixing boxes, and an inclined plate is slidably connected inside the sliding groove, and an insert plate is installed on one side of the inclined plate, and the insert plate is plugged into the mounting plate, and one side of the mounting frame is fixedly connected to the mounting plate.

[0010] Preferably, limiting grooves are symmetrically provided on the inner side of the installation frame, and one side of the slide plate is slidably connected to the limiting grooves.

[0012] Preferably, a guide groove is formed inside one end of the fixed box, a connecting block is slidably connected inside the guide groove, one end of the inclined plate is fixedly connected to the connecting block, and a third telescopic spring is installed between the connecting block and the inside of the guide groove.

[0013] Preferably, a third shock-absorbing rubber block is installed between the mounting plate and the protection plate.

[0014] Preferably, the push block is slidably connected inside the installation groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this high-speed RGV car with limit and anti-disengagement, the specific content is as follows: when the two sides of the car body are impacted by external forces, at this time, the protection plate is impacted and the distance between it and the car body becomes narrower, so that the sliding frame can be driven to slide outside the support rod, and then the first telescopic spring contracts, realizing the effect of longitudinal buffering. Then, the movement of the sliding frame drives the two groups of connecting rods to rotate, and the rotation of the connecting rods pushes the sliding plate to slide inside the two ends of the installation frame, and then the push plate slides inside the connecting frame, and then the retractable rod and the second telescopic spring contract, thus realizing the effect of transverse buffering. Furthermore, through longitudinal and transverse buffering, the shock feeling is absorbed layer by layer, thereby greatly reducing the impact intensity of the external force on the protection plate, and then being able to reduce the phenomenon of the car body deviating and derailing, having a certain function of anti-collision and limiting for the car body. By rotating the screw rod to drive the rotation inside the installation groove, the push block can be driven to slide inside the inner side of the installation groove. Through the cooperation between the convex slope on the surface of the push block and the inclined plate, the inclined plate can be pushed to slide inside the fixed box, and then multiple plug plates are inserted into the mounting plate, thus being able to achieve the effect of quickly installing and disassembling the mounting plate, and then being able to facilitate the staff to detect and repair the protection mechanism, greatly improving the daily maintenance efficiency of the staff.

[0016] 1. When an external force impacts both sides of the vehicle body, first, the protective plates on both sides of the vehicle body are impacted first. Since the protective plates are impacted, the distance between them and the vehicle body becomes narrower, which can drive the sliding frame to slide inside the installation frame. At this time, the sliding frame slides outside the support rod, causing the first telescopic spring to contract, achieving the effect of longitudinal buffering. Then, the movement of the sliding frame drives the rotation of two groups of connecting rods. The rotation of the connecting rods pushes the sliding plate to slide inside both ends of the installation frame, causing the push plate to slide inside the connecting frame, and further causing the contraction rod and the second telescopic spring to contract, thus achieving the effect of transverse buffering. Through longitudinal and transverse buffering, the shock feeling is absorbed layer by layer, greatly reducing the impact intensity of the external force on the protective plate, reducing the phenomenon of the vehicle body deviating and derailing, having a certain anti-collision and limiting function for the vehicle body, improving the safety of the vehicle body, reducing losses caused by collisions, and enhancing the stability of the vehicle body. Through the design of the first shock-absorbing rubber block, the second shock-absorbing rubber block, and the third shock-absorbing rubber block, the buffering effect of the protective plate on the external force can be further improved, bringing convenience to the staff during use;

[0017] 2. By inserting the installation plate into both sides of the vehicle body and then driving the rotation inside the installation groove by rotating the screw rod, the push block can be driven to slide inside the installation groove. Through the cooperation between the convex slope on the surface of the push block and the inclined plate, the inclined plate can be pushed to slide inside the fixed box, and multiple groups of plug plates are inserted into the installation plate, thus achieving the effect of quickly installing and disassembling the installation plate, facilitating the detection and maintenance of the protection mechanism by the staff, greatly improving the daily maintenance efficiency of the staff, and bringing convenience to the staff during use.

[0029] Working principle: Before using this kind of high-speed RGV car with limit and anti-disengagement, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 6As shown in the figure, when the two sides of the vehicle body 101 are impacted by an external force, first, the protective plates 2011 on both sides of the vehicle body 101 are impacted first. Since the protective plates 2011 are impacted, the distance between them and the vehicle body 101 becomes narrower, which can drive the sliding frame 204 to slide inside the mounting frame 201. At this time, the sliding frame 204 slides outside the support rod 203, and then the first telescopic spring 205 contracts, achieving the effect of longitudinal buffering. Then, the movement of the sliding frame 204 drives the two groups of connecting rods 208 to rotate. The rotation of the connecting rods 208 pushes the sliding plate 207 to slide inside the two ends of the mounting frame 201, and then the push plate 209 slides inside the connecting frame 202, and then the retractable rod 210 and the second telescopic spring 211 contract, thus achieving the effect of lateral buffering. Furthermore, through the longitudinal and lateral buffering, the shock feeling is absorbed layer by layer, which greatly reduces the impact intensity of the external force on the protective plate 2011, and can reduce the phenomenon of the vehicle body 101 deviating and derailing. It has a certain anti-collision and limiting function for the vehicle body 101, which can improve the safety of the vehicle body 101, reduce the losses caused by collisions, and also enhance the stability of the vehicle body 101. Through the design of the first shock-absorbing rubber block 213, the second shock-absorbing rubber block 214, and the third shock-absorbing rubber block 215, the buffering effect of the protective plate 2011 on the external force can be further improved, bringing convenience to the staff during use. Since one side of the sliding plate 207 is slidably connected to the limiting groove 212, the movement of the sliding plate 207 can be made more stable;

[0030] By inserting the mounting plate 301 into the two sides inside the vehicle body 101, and then driving the rotation inside the mounting groove 303 by rotating the screw rod 304, the push block 305 can be driven to slide inside the mounting groove 303. Through the cooperation between the convex slope on the surface of the push block 305 and the inclined plate 307, the inclined plate 307 can be pushed to slide inside the fixed box 302, and then multiple plug plates 308 are inserted into the mounting plate 301, thus achieving the effect of quickly installing and disassembling the mounting plate 301, and then facilitating the detection and maintenance of the protection mechanism 2 by the staff, greatly improving the daily maintenance efficiency of the staff, and bringing convenience to the staff during use. The movement of the inclined plate 307 drives the connecting block 310 to slide inside the guide groove 309. At this time, the third telescopic spring 311 contracts. Through the resetting property of the third telescopic spring 311, the subsequent reset movement of the inclined plate 307 can be assisted, bringing convenience to the staff during use.
