Description

Technical Field

[0001] The utility model relates to the technical field of RGV, in particular to an RGV conveying device with a self-contained lifting platform. Background Art

[0002] With the popularity of Industry 4.0, automated transportation equipment is becoming more and more popular. With the logistics industry and automobile manufacturing and assembly industry as pioneers, other traditional manufacturing and assembly industries are also using automated transportation equipment. The trolley is the main carrier and worker for the transportation of goods and pallets. It consists of a traveling trolley and a chain conveyor. The trolley travels forward on two ground tracks, and the chain conveyor is mounted on the trolley to pick up and deliver pallets and goods. The ground track integrates the power supply system, communication system, and positioning system. The trolley integrates the power supply system, information reading interaction system, and position reading interaction system;

[0003] Traditional RGV carts can generally only perform simple position transfer of items and parts, and cannot adjust the storage height, so workers are required to carry items up and down. As a result, the transportation efficiency of traditional RGV carts cannot meet the needs of some manufacturing and assembly industries. In order to solve this problem and improve the transportation efficiency and transportation range of automated transportation equipment, an RGV conveying device with its own lifting platform is designed. Utility Model Content

[0004] The main purpose of the utility model is to provide an RGV conveying device with a self-contained lifting platform, which can effectively solve the problem that the traditional RGV trolley cannot be lifted or lowered to adjust the storage height of articles, resulting in general conveying efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An RGV conveying device with a built-in lifting platform comprises a trolley frame, a conveyor body is installed at both ends of the trolley frame, a sliding trolley group and an active trolley group are fixedly installed on the lower side of the trolley frame, a guide wheel group is fixedly installed on the bottom of the sliding trolley group and the active trolley group, a lifting component for lifting drive is installed inside the trolley frame, and a storage platform for storing articles is fixedly installed on the upper end of the lifting component.

[0007] Preferably, the lifting assembly includes an assembly frame, a first support frame and a second support frame. The upper ends of the first support frame and the second support frame are rotatably connected to the storage platform. The middle parts of the first support frame and the second support frame are rotatably installed with a connecting shaft. The assembly frame is fixedly installed inside the trolley frame.

[0008] Preferably, the lower end of the first support frame is slidably mounted inside the component frame, and the lower end of the second support frame is rotatably mounted inside the component frame.

[0009] Preferably, a transfer roller is installed on the lower side of the second support frame, and a second take-up roller is movably connected to the upper side of the second support frame via a contraction spring.

[0010] Preferably, a rotating seat is fixedly installed on one side of the component frame, and a first belt-taking roller is rotatably installed inside the rotating seat. A lifting platform motor is fixedly installed on one end of the component frame, and the output end of the lifting platform motor is fixedly connected to the first belt-taking roller. The first belt-taking roller and the second belt-taking roller are connected to a pulling belt through a transfer roller.

[0011] Preferably, a conveyor motor is fixedly mounted on one end of the trolley frame, and an output end of the conveyor motor is connected to the conveyor body.

[0012] Preferably, anti-collision barriers are fixedly installed at both ends of the trolley frame, and guardrails are fixedly installed on the upper surface of the trolley frame and on both sides of the storage platform.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The present application utilizes lifting components to significantly improve efficiency. The overall frame structure of the present application is completely different from the overall frame structure design concept of a traditional trolley. On the basis of a traditional trolley, the overall frame is welded to improve the strength of the vehicle body, and the vehicle body is enlarged due to the lifting components. The overall frame structure of a traditional trolley only ensures strength. The overall frame structure of the present application improves the carrying capacity while ensuring strength. Compared with traditional trolleys, the present application has a wider range of applications, more stable operation, and greater space utilization, making automated transportation equipment more and more popular.

[0015] (2) By starting the lifting platform motor to rotate forward, the first belt roller is driven to rotate and the belt is reeled in, so that the belt pulls the second belt roller toward the middle of the application and causes the lower end of the first support frame to retract inward, thereby lifting the storage platform upward under the action of the connecting shaft. Similarly, starting the lifting platform motor to rotate reversely makes the belt looser, and then the storage platform is pressed downward under the influence of gravity, and causes the lower end of the first support frame to expand outward, thereby realizing the descent of the storage platform. The above structure can realize automatic lifting and lowering operation of the storage platform, which can adapt to different work needs, greatly increase the space for trolley transportation, and further improve the efficiency during transportation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, an RGV conveying device with a built-in lifting platform includes a trolley frame 2, a conveyor body 1 is installed at both ends of the trolley frame 2, a sliding trolley group 4 and an active trolley group 5 are fixedly installed on the lower side of the trolley frame 2, a guide wheel group 6 is fixedly installed at the bottom of the sliding trolley group 4 and the active trolley group 5, a lifting component 8 for lifting drive is installed inside the trolley frame 2, and a storage platform 10 for storing articles is fixedly installed on the upper end of the lifting component 8.

[0023] There are six wheel groups at the bottom of the trolley frame 2. The positions of the wheel groups can be referred to Figure 3 , one side is two sets of active trolley groups 5. The other side is two sets of sliding trolley groups 4. Each wheel group is provided with four sets of guide wheel groups 6, which are symmetrically arranged up and down, four along the upper edge of the track, and four along the lower edge of the track, so that the trolley keeps running on the track.

[0024] In this embodiment, the lifting assembly 8 includes an assembly frame 801, a first support frame 802 and a second support frame 803. The upper ends of the first support frame 802 and the second support frame 803 are rotatably connected to the storage platform 10. The middle parts of the first support frame 802 and the second support frame 803 are rotatably installed with a connecting shaft 808. The assembly frame 801 is fixedly installed inside the trolley frame 2.

[0025] In this embodiment, the lower end of the first support frame 802 is slidably installed inside the component frame 801, and the lower end of the second support frame 803 is rotatably installed inside the component frame 801.

[0026] In this embodiment, a transfer roller 806 is installed on the lower side of the second support frame 803, and a second take-up roller 809 is movably connected to the upper side of the second support frame 803 via a contraction spring.

[0027] In this embodiment, a rotating seat 804 is fixedly installed on one side of the component frame 801, and a first belt-taking roller 805 is rotatably installed inside the rotating seat 804. A lifting platform motor 7 is fixedly installed on one end of the component frame 801, and the output end of the lifting platform motor 7 is fixedly connected to the first belt-taking roller 805. The roller bodies of the first belt-taking roller 805 and the second belt-taking roller 809 are connected to a pulling belt 807 through a transfer roller 806.

[0028] By starting the lifting platform motor 7 to rotate forward, the first belt roller 805 is driven to rotate, and the reeling belt 807 is rolled up, so that the reeling belt 807 pulls the second belt roller 809 toward the middle of the application, and the lower end of the first support frame 802 is retracted inward, so that the storage platform 10 is lifted upward under the action of the connecting shaft 808.

The guardrails 3 are provided to ensure the minimum distance between the trolleys when the barcode system fails, thereby preventing mechanical damage.

[0031] The working principle of the RGV conveying device with its own lifting platform:

[0032] When in use, the conveyor motor 11 is started to drive the conveyor body 1 to quickly store the items on the storage platform 10, and then the active trolley group 5 is started to cooperate with the sliding trolley group 4 to drive the trolley frame 2 to move as a whole, so as to move the position of the items;

[0033] After the object is moved to the desired position, the lifting platform motor 7 is started to rotate forward to drive the first take-up roller 805 to rotate, and the take-up belt 807 is rolled up, so that the take-up belt 807 pulls the second take-up roller 809 to approach the middle of the application, and the lower end of the first support frame 802 is retracted inward, so that under the action of the connecting shaft 808, the storage platform 10 is lifted upward, so that it is convenient for personnel to quickly take out the objects;

[0034] After the items are taken out, the lifting platform motor 7 is started to reverse, so that the pulling belt 807 becomes loose, and then the storage platform 10 is pressed downward under the influence of gravity, and the lower end of the first support frame 802 is expanded outward, so as to realize the descent of the storage platform 10 and reset the storage platform 10 to cooperate with the conveyor body 1 for the next round of rapid material storage, thereby realizing efficient transportation operations.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
