Description

Technical Field

[0001] The utility model belongs to the field of transport equipment, in particular to an automatic screw transport vehicle. Background Art

[0002] Some film manufacturing companies need to use plastic extrusion equipment. Usually, this plastic extrusion equipment is equipped with a large screw for stirring and pushing plastic raw materials. When a batch of plastic raw materials is extruded, the plastic extrusion equipment needs to be stopped for cleaning and the screw in the plastic extrusion equipment needs to be taken out. However, the screw weighs several tons, and the equipment needs to be used for transportation after the screw is taken out. Currently, the commonly used transportation equipment is a trolley that needs to be pushed by manpower. There are two problems with this type of transportation equipment. First, the trolley needs to be pushed manually to undertake and transport the screw, which may cause the trolley to collapse and the screw to injure the staff. Second, the screw is long, and the scene of transporting the screw is indoors. The turning radius of the general trolley is too large, which is inconvenient to operate. Therefore, it is necessary to provide a screw automatic transporter that can automatically transport the screw and has flexible turning. Utility Model Content

[0003] The utility model aims to provide an automatic screw transporter to solve the technical problems that when a trolley is manually pushed to receive and transport the screw, the trolley may collapse and the screw may injure the staff, and the screw is long and the screw is transported indoors, and the turning radius of the general trolley is too large, which makes the operation inconvenient.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] A screw automatic transport vehicle includes: a base: including a chassis and universal wheels arranged in a rectangular shape around the chassis; a receiving platform: provided with a base for receiving and limiting the screw; a lifting component: supported between the base and the receiving platform; a QR code navigation component: including a QR code sticker and a code reader, the QR code sticker is laid on the ground along the travel path of the automatic transport vehicle, and the code reader is installed on the side of the chassis close to the ground. Through such a design, the code reader can locate the screw automatic transport vehicle by identifying the information contained in the QR code sticker and obtain the next operation instruction, so that the screw automatic transport vehicle can automatically transport the screw along a fixed route, and the universal wheel provides convenience for the screw automatic transport vehicle to rotate in a small indoor space.

[0006] Furthermore, a motor is provided in the chassis, and the motor is connected to the universal wheel. The universal wheel is a Mecanum wheel. There are four Mecanum wheels, including two left-handed Mecanum wheels and two right-handed Mecanum wheels. Along the forward direction of the screw automatic transport vehicle, the left front wheel is a right-handed Mecanum wheel; the right front wheel is a left-handed Mecanum wheel; the left rear wheel is a left-handed Mecanum wheel; and the right rear wheel is a right-handed Mecanum wheel. With such a design, the Mecanum wheel can enable the screw automatic transport vehicle to achieve multi-directional translation, preventing the inconvenience of indoor transportation due to the excessive length of the screw.

[0007] Furthermore, the base includes at least one set of symmetrically arranged bosses, the bosses have inclined surfaces that are arranged opposite to each other and tilt away from the opposite bosses from low to high, and the inclined surfaces of the two bosses cooperate to form a receiving position for the screw. With such a design, screws of different thicknesses can be transported, and the screws can be limited to prevent them from rolling down during transportation.

[0008] Furthermore, the inclined surface and the receiving platform are partially paved with a flexible layer. This design can prevent the screw from being damaged during transportation and reduce its service life.

[0009] Furthermore, the lifting assembly includes an upper table, a lower table, an outer bracket, an inner bracket and a hydraulic rod, the upper table is arranged parallel to the lower table, and support rods are provided at the end positions of the outer bracket and the inner bracket, the outer bracket and the inner bracket are cross-supported between the upper table and the lower table, one end of the outer bracket is rotatably fixed to the upper table; a roller is provided at the other end to cooperate and abut against the lower table, and one end of the inner bracket is rotatably fixed to the lower table; a roller is provided at the other end to cooperate and abut against the upper table, a rotation fixing part is passed through the overlapping part of the outer bracket and the inner bracket, a force-bearing rod is provided at the middle position of the inner bracket, the hydraulic rod is supported between the force-bearing rod and the support rod of the outer bracket close to the chassis, and the two ends of the hydraulic rod are respectively rotatably fixed to the force-bearing rod and the support rod of the outer bracket close to the chassis. With such a design, when the screw is pulled out of the extrusion equipment, the lifting assembly drives the receiving platform to descend and wait at a predetermined position. After the screw is extended to a certain distance, the lifting assembly lifts the receiving platform to abut against the screw.

[0010] Furthermore, a notch is provided on one side of the chassis close to the ground, and the code reader is arranged in the notch. By means of such a design, obstacles on the driving path of the screw automatic transport vehicle are prevented from damaging the code reader.

[0011] Furthermore, the receiving platform is provided with a distance sensor. With such a design, when the screw automatic transport vehicle reaches the predetermined position to prepare to transport the screw, the distance change between the receiving surface and its upper portion is detected to determine whether the screw has extended to the position of the screw automatic transport vehicle, thereby controlling the lifting of the lifting device.

[0012] Furthermore, the screw automatic transport vehicle includes at least two vehicles, and a receiving platform of one of the screw automatic transport vehicles is provided with a baffle. With such a design, the transport vehicle provided with the baffle is at the end position of the screw during transport, and when the screw is pushed into the extrusion device, the baffle pushes the end of the screw.

[0013] The beneficial effects of the utility model are as follows: the code reader locates the screw automatic transport vehicle and obtains the next operation instruction by identifying the information contained in the two-dimensional code sticker, so that the screw automatic transport vehicle can automatically transport the screw along a fixed route, and the universal wheel provides convenience for the screw automatic transport vehicle to rotate in a small indoor space.

DETAILED DESCRIPTION

[0020] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0021] It should be noted that the method for removing the screw of some extrusion equipment is to remove some parts and then push one end of the screw forward so that the screw is slowly pulled out from the other end. The present disclosure is most suitable for this type of extrusion equipment.

[0022] Example 1

[0023] A screw automatic transport vehicle comprises: a base, which comprises a chassis 1 and universal wheels arranged in a rectangular shape around the chassis 1; a receiving platform, which comprises a base 4 for receiving and limiting a screw 3; a lifting component, which is supported between the base and the receiving platform; a QR code navigation component, which comprises a QR code sticker and a code reader 5, wherein the QR code sticker is laid on the ground along the travel path of the automatic transport vehicle, and the code reader 5 is installed on the side of the chassis 1 close to the ground.

[0024] A motor is provided in the chassis 1, and the motor is drivingly connected to the universal wheel. The universal wheel is a Mecanum wheel 6, and four Mecanum wheels 6 are provided. The Mecanum wheels 6 include two left-handed Mecanum wheels 6 and two right-handed Mecanum wheels 6. Along the forward direction of the screw automatic transport vehicle, the left front wheel is a right-handed Mecanum wheel 6; the right front wheel is a left-handed Mecanum wheel 6; the left rear wheel is a left-handed Mecanum wheel 6; and the right rear wheel is a right-handed Mecanum wheel 6.

[0025] The implementation of the above embodiment is as follows:

[0026] The QR code will be accompanied by specific information, such as location, direction and operation. The screw automatic transport vehicle obtains this information through the code reader 5, and sets the QR code evenly on the ground to control the movement of the screw automatic transport vehicle, so that the transportation process is automated to prevent workers from being hit by the screw 3.

[0027] Example 2

[0028] The base 4 includes at least one group of symmetrically arranged bosses 7, each of which has inclined surfaces that are relatively arranged and inclined away from the opposite boss 7 from low to high. The inclined surfaces of the two bosses 7 cooperate to form a receiving position for the screw 3.

[0029] A flexible layer 8 is laid on the inclined surface and part of the receiving platform.

[0030] The implementation method of the above embodiment is as follows: the receiving position formed by the two bosses 7 supports the screw rod 3, and due to the setting of the inclined surface, the screw rods 3 of different thicknesses can be adapted to the receiving position.

[0031] Example 3

[0032] The lifting assembly includes an upper table 9, a lower table 10, an outer bracket 11, an inner bracket 12 and a hydraulic rod 13. The upper table 9 is arranged in parallel with the lower table 10. The end positions of the outer bracket 11 and the inner bracket 12 are provided with support rods 14. The outer bracket 11 and the inner bracket 12 are cross-braced between the upper table 9 and the lower table 10. One end of the outer bracket 11 is rotatably fixed to the upper table 9; the other end is provided with a roller 15 that cooperates with the lower table 10. The inner bracket 1 2 is rotatably fixed to the lower table 10; the other end is provided with a roller 15 which cooperates with the upper table 9, a rotatable fixing member 2 is penetrated at the intersection of the outer bracket 11 and the inner bracket 12, a force rod 16 is provided at the middle position of the inner bracket 12, and the hydraulic rod 13 is supported between the force rod 16 and the support rod 14 of the outer bracket 11 close to the chassis 1, and the two ends of the hydraulic rod 13 are rotatably fixed to the force rod 16 and the support rod 14 of the outer bracket 11 close to the chassis 1.

[0033] A notch 17 is formed on a side of the chassis 1 close to the ground, and the code reader 5 is disposed in the notch 17 .

[0034] The implementation method of the above embodiment is as follows: the hydraulic rod 13 changes the distance between the force-bearing rod 16 and the support rod 14 on the side of the outer bracket 11 close to the chassis 1 by telescoping, but since the force-bearing rod 16 and the support rod 14 are both fixed parts, and the outer bracket 11 and the inner bracket 12 are penetrated by the rotating fixed part 2, the outer bracket 11 and the inner bracket 12 can only change the crossing angle by rotating the fixed part 2 to adapt to the push of the hydraulic rod 13, and the crossing angle between the inner bracket 12 and the outer bracket 11 changes, and the distance between the upper table 9 and the lower table 10 will also change, thereby realizing the lifting and lowering of the upper table 9.

[0035] Example 4

[0036] The receiving platform is provided with a distance sensor 18 .

[0037] The screw rod automatic transport vehicle comprises at least two vehicles, and a baffle 19 is provided on the receiving platform of one of the screw rod automatic transport vehicles.

[0038] The implementation method of the above embodiment is: before the two screw automatic transport vehicles reach the extrusion position of the screw 3 according to the instructions of the QR code sticker, the screw automatic transport vehicle without the baffle 19 is the vehicle a and is closer to the extrusion position, and the screw automatic transport vehicle with the baffle 19 is the vehicle b and is far away from the extrusion position.

[0039] When the screw 3 is slowly extended, the screw 3 first passes over the top of the trolley a and is detected by the distance sensor 18, but the lifting component of the trolley a is not lifted at this time. When the screw 3 is extended to the top of the trolley b and is detected by the distance sensor 18, the lifting component of the trolley b is lifted, and the trolley b receives the screw 3 and moves forward as the screw 3 is extended. After a certain period of time (calculated based on the distance between the trolley a and the trolley b, the length of the screw 3 and the extension speed of the screw 3), the lifting component of the trolley a is lifted. At this time, the screw 3 is lifted by the trolley a and the trolley b, and then the screw 3 is transported according to the instructions of the QR code sticker.
