[0002] Logistics warehousing refers to a series of activities that use self-built or leased warehouses and sites to store, keep, load, unload, and distribute goods. It is not only a means of material storage, but also an indispensable part of the modern logistics system. The main functions of logistics warehousing include: storage function, ensuring the safe and orderly storage of goods through reasonable arrangement of storage space to cope with market demand fluctuations; safekeeping function, properly keeping inventory goods to prevent damage, loss or deterioration, and ensuring the quality of goods; sorting and packaging, quickly and accurately sorting inventory goods according to order requirements, and carrying out necessary packaging processing; distribution function, delivering the sorted goods to the designated location through appropriate transportation methods according to customer requirements; information processing, realizing inventory monitoring, order processing, logistics tracking and other functions through information technology to improve operational efficiency.

[0003] When loading and unloading goods in logistics warehouses, trucks will be driven to designated locations for loading and unloading. In order to ensure safe operation and prevent the truck from slipping and causing safety accidents, the truck tires will be assisted in blocking. Currently, there are also various types of automatic blocking devices, whose structure is generally that the driving source drives the blocking components on both sides to move synchronously, and the tires on both sides of the truck are clamped in a limited position.

[0004] However, since the truck is not necessarily straight after reversing, the tires on both sides of the truck may not completely abut against the blocking components, and there may be a gap on one side, posing certain safety hazards. Utility Model Content

[0005] In view of the above problems, the utility model provides a vehicle positioning device for a logistics warehouse, which can effectively solve the problem of safety hazards caused by incomplete abutment between tires and blocking components.

[0006] The technical solution adopted to solve the above technical problems is: a vehicle positioning device for a logistics warehouse, including a platform, two blocks and a matching piece. The two blocks are respectively slidably connected to the two sides of the platform, and an arc surface is set on the upper side of the block. The two blocks can be moved forward and backward for fine adjustment. Each block is slidably connected with a matching piece on both sides, and the matching piece rotates along the curvature of the block. The upper side of the matching piece is set with an arc surface, and the arc surface of the matching piece is flush with the arc surface of the block.

[0007] Further, it further includes an installation groove, a limiting strip, and a sliding groove. Installation grooves are formed on both sides of the blocking member. The cooperating member is connected in the installation groove. Limiting strips are connected to both sides of the cooperating member. The limiting strip has the same curvature as the cooperating member. A sliding groove matching the limiting strip is formed on the blocking member, and the limiting strip slides in the sliding groove.

[0008] Further, it further includes two locking racks, two locking gears, a first hydraulic cylinder, two friction wheels, and two cooperating wheels. The two locking racks correspond to the blocking member. The locking racks are connected to the lower side of the blocking member. The two locking gears are respectively rotatably connected to both sides inside the platform. The locking gears mesh with the corresponding locking racks. The first hydraulic cylinder is connected inside the platform. The first hydraulic cylinder is a two-way hydraulic cylinder. The two friction wheels are respectively connected to the output shafts on both sides of the first hydraulic cylinder. The two cooperating wheels are respectively coaxially fixed to the locking gears. The friction wheels and the cooperating wheels are engaged to achieve braking.

[0009] Further, it further includes an arc rack, a double-shaft motor, and a spur gear. An arc rack is connected to the outside of the cooperating member. A double-shaft motor is connected inside each blocking member. Spur gears are connected to the output shafts on both sides of the double-shaft motor. The spur gears mesh with the corresponding arc racks.

[0010] Further, it further includes a return spring and two second hydraulic cylinders. Return springs are connected to both sides of the blocking member along the sliding direction. The two second hydraulic cylinders are respectively connected to both sides inside the platform. The second hydraulic cylinders correspond to the blocking member. The output end of the second hydraulic cylinder abuts against the side surface of the blocking member.

[0011] Further, it further includes a plurality of folding telescopic plates. A plurality of folding telescopic plates are connected to both sides of the blocking member.

[0012] The beneficial effects of the present utility model are as follows: Through the two sliding blocking members, fine-tuning is respectively performed by moving forward and backward. When the truck reverses to the loading and unloading point, the truck is not in a proper state. For the two rear wheels on both sides of the truck, there is a situation where one is in front and the other is behind with a gap relative to the blocking member. At this time, the blocking member on the side with the adjustable gap can move until the blocking member is in full contact with the rear wheel on that side. Due to the integrated setting of the cooperating member and the blocking member, the cooperating member and the blocking member move synchronously, and there is no need to additionally adjust the position of the cooperating member. After the rear blocking member is in contact with the rear wheel, only by rotating the cooperating member can the tire be quickly clamped. The arc-shaped surfaces on the upper sides of the blocking member and the cooperating member provide better stability when clamping the tire, thereby effectively solving the problem of potential safety hazards caused by the incomplete contact between the tire and the blocking component.

Detailed implementation manners

[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] As Figures 1-6 shown, a vehicle positioning device for a logistics warehouse provided in this embodiment includes a platform 1, two stoppers 2 and fittings 3. The two stoppers 2 are respectively slidably connected to both sides of the platform 1, and the upper arc surface of the stopper 2 is arranged. The two stoppers 2 can be respectively moved back and forth for fine adjustment. A fitting 3 is slidably connected to both sides of each stopper 2, and the fitting 3 rotates along the arc of the stopper 2. The upper arc surface of the fitting 3 is arranged, and the arc surface of the fitting 3 is flush with the arc surface of the stopper 2.

[0022] In the above embodiments, through the two slidably arranged stoppers 2, fine adjustment is performed by moving back and forth respectively. When the truck reverses to the loading and unloading point, the truck is not in a straight state. For the two rear wheels of the truck relative to the stopper 2, there is a situation where there is a gap between the front and the back. At this time, the stopper 2 on the side of the gap can be adjusted to move until the stopper 2 is in full contact with the rear wheel on that side. Through the integrated setting of the fitting 3 and the stopper 2, the fitting 3 and the stopper 2 move synchronously, and there is no need to additionally adjust the position of the fitting 3. After the rear stopper 2 is in contact with the rear wheel, only by rotating the fitting 3 can the tire be quickly clamped. The settings of the upper arc surfaces of the stopper 2 and the fitting 3 provide better stability when clamping the tire, thereby effectively solving the problem of potential safety hazards caused by the incomplete contact between the tire and the blocking component.

[0023] Specifically, it further includes an installation groove 4, a limiting strip 5 and a sliding groove 6. Installation grooves 4 are provided on both sides of the blocking member 2. The cooperating member 3 is connected in the installation groove 4. Limiting strips 5 are connected to both sides of the cooperating member 3. The limiting strip 5 has the same radian as the cooperating member 3. A sliding groove 6 matching the limiting strip 5 is provided on the blocking member 2, and the limiting strip 5 slides in the sliding groove 6.

[0024] In the above embodiments, through the cooperation of the limiting strip 5 and the sliding groove 6, the stable rotational sliding operation of the cooperating member 3 is realized.

[0025] Specifically, it further includes two locking racks 7, two locking gears 8, a first hydraulic cylinder 9, two friction wheels 10 and two cooperating wheels 11. The two locking racks 7 correspond to the blocking member 2. The locking rack 7 is connected to the lower side of the blocking member 2. The two locking gears 8 are respectively rotatably connected to both sides inside the platform 1. The locking gear 8 meshes with the corresponding locking rack 7. The first hydraulic cylinder 9 is connected inside the platform 1. The first hydraulic cylinder 9 is a two-way hydraulic cylinder. The two friction wheels 10 are respectively connected to the output shafts on both sides of the first hydraulic cylinder 9. The two cooperating wheels 11 are respectively fixedly connected coaxially with the locking gears 8. The friction wheel 10 and the cooperating wheel 11 are engaged to achieve braking.

[0026] In the above embodiments, when the blocking members 2 on both sides are in close contact with the truck tire, the first hydraulic cylinder 9 can be operated. The output shafts on both sides of the first hydraulic cylinder 9 extend simultaneously, pushing the friction wheel 10 and the cooperating wheel 11 to engage. There is good friction between the friction wheel 10 and the cooperating wheel 11, thereby braking and locking the locking gear 8, making the locking rack 7 no longer move, and further locking the blocking member 2.

[0027] Specifically, it further includes an arc rack 12, a double-shaft motor 13 and a spur gear 14. An arc rack 12 is connected to the outside of the cooperating member 3. A double-shaft motor 13 is connected inside each blocking member 2. Output shafts on both sides of the double-shaft motor 13 are both connected with spur gears 14, and the spur gears 14 mesh with the corresponding arc racks 12.

[0028] In the above embodiments, by rotating the double-shaft motor 13 to drive the spur gears 14 on both sides, the two cooperating members 3 on the blocking member 2 are synchronously driven to extend and retract.

[0029] Specifically, it further includes a return spring 15 and two second hydraulic cylinders 16. Return springs 15 are connected to both sides of the blocking member 2 along the sliding direction. The two second hydraulic cylinders 16 are respectively connected to both sides inside the platform 1. The second hydraulic cylinder 16 corresponds to the blocking member 2, and the output end of the second hydraulic cylinder 16 abuts against the side surface of the blocking member 2.

[0030] In the above embodiments, when there is no truck on the platform 1, the return spring 15 causes the stopper 2 to be in the initial state. When the truck reverses into the loading and unloading location, the second hydraulic cylinder 16 pushes the stopper 2 to tightly abut against the rear wheels of the truck. The output end of the hydraulic cylinder is in a separated state from the stopper 2 and only makes abutting and pushing movements.

[0031] Specifically, it further includes a plurality of folding telescopic plates 17, and a plurality of folding telescopic plates 17 are connected to both sides of the stopper 2.

[0032] In the above embodiments, the folding telescopic plates 17 shield the notch, having a dust-proof and protective effect.

[0033] The working principle of the present utility model is as follows: The platform 1 is installed at the loading and unloading port of the logistics warehouse. When the truck reverses onto the platform 1, the rear wheels of the truck abut against the stopper 2, or there is a gap on one side without abutting. The rear wheels of the truck can push the stopper 2 to slide. At this time, the return spring 15 is compressed, and the stopper 2 drives the locking rack 7 to move, and the locking gear 8 rotates synchronously;

[0034] After the truck stops, the two second hydraulic cylinders 16 on both sides are operated to respectively push the stoppers 2 on both sides, so that the stoppers 2 tightly abut against the truck tires. During this process, the locking rack 7 and the locking gear 8 move synchronously. Then, the first hydraulic cylinder 9 is operated to push the friction wheels 10 on both sides, and the friction wheels 10 on both sides are engaged with the mating wheels 11 to achieve braking, achieving a good braking effect on the locking gear 8, the locking rack 7, and the stopper 2. Then, the second hydraulic cylinders 16 can be retracted;

[0035] Then, the two double-shaft motors 13 on both sides are operated. The double-shaft motors 13 drive the spur gears 14 on both sides to rotate, and further drive the arc-shaped rack 12 to rotate, so that the fitting 3 rotates out of the stopper 2 and cooperates with the stopper 2 to clamp the tire.

[0036] As described above.
