Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and in particular to a forklift telescopic boom lift and a forklift. Background Technology

[0002] With the implementation of the automated warehousing and logistics project for tire blanks (forming-vulcanization), the formed tire blanks in the forming area are transported to the EMS gripping station in the vulcanization area via a steel structure platform. The tire blank logistics transportation in the vulcanization area adopts a linear reciprocating EMS conveyor system. Tracks are erected in the vulcanization area, and EMS trolleys transport the tire blanks in the air. Partial failures and blockages in the EMS conveyor system can cause the EMS to be unable to grip the tire blanks at the gripping position, resulting in an entire row of vulcanizing machines waiting for tire blanks and stopping production. At this time, a forklift needs to pick up the pallet and lift it up to pick up the tire blank. Two people are needed to work together to lift the tire blank from the conveyor line and place it in the forklift pallet. The forklift driver then lowers it to the corresponding vulcanizing machine storage trolley, and two more people are needed to move the tire blank from the forklift pallet to the storage position on the storage trolley.

[0003] The process of transferring tire blanks after an EMS failure is as follows: a forklift picks up a pallet - the pallet is raised to a steel platform - two people load the tires onto the steel platform - the forklift is lowered to the ground and transferred to the corresponding tire storage trolley - two people on the ground then move the tire blanks to the tire storage trolley. It requires five people to handle this kind of abnormal situation, which has high operating costs and cannot guarantee the continuity of tire blank production. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a forklift telescopic boom lifter and forklift, which uses mechanical claws in conjunction with the forklift to grab tire blanks, thereby improving the efficiency of tire blank picking and placing and ensuring the continuity of the production process.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a forklift telescopic boom lift, including a telescopic boom, one end of which is equipped with a mechanical claw, and the other end is used to connect to a forklift; The boom has a portal frame structure, and a first hydraulic cylinder is installed on the telescopic section of the boom. The boom is equipped with a vehicle-mounted wireless monitoring unit, which is used to acquire the gripping status of the mechanical claw. The mechanical claw includes multiple claw parts evenly distributed around the second hydraulic cylinder.

[0006] As a further implementation, the boom includes a support arm, an inner sleeve, and a connecting pipe, wherein the support arm has an L-shaped structure; One end of the inner sleeve is inserted into the support arm, and the other end is connected to the connecting pipe; the second oil cylinder is fixed to the lower end of the connecting pipe.

Detailed Implementation

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Terminology Explanation: EMS tire positioning: When there are 30 minutes left before the vulcanizing machine starts boiling, the tire will be called. The tire blank conveying system will automatically transport the tire blank to the vulcanizing steel platform above the tire positioning point, below the starting point of the EMS aerial trolley.

[0023] EMS Conveying System: The EMS aerial trolley lowers and grabs the tire blanks on the steel platform conveyor line, then rises and travels to the docking point of the corresponding vulcanizing machine tire storage trolley, completing the descent-release-rise-return to the starting point to wait for tire grabbing.

[0024] Tire storage trolley: Located directly in front of the vulcanizing machine steam pot, it is equipped with a tire tray to receive tires lowered by the EMS aerial trolley and transport them along the guide rail to the vulcanizing machine's robotic arm gripping position.

[0025] Example 1: In existing forklift tire loading and unloading processes, multiple people are required, resulting in high labor intensity, low efficiency, and inability to guarantee production continuity. Therefore, this embodiment provides a forklift telescopic boom lifting device, such as... Figures 1-4 As shown, it includes a mechanical claw 19, which grasps the tire blank through the lifting action of the mechanical claw 19; the mechanical claw 19 is installed at one end of the support arm 5, and the other end of the support arm 5 is used to connect to the forklift.

[0026] The outrigger 5 has an L-shaped structure, consisting of a horizontal section and a vertical section, with reinforcing ribs installed between the two sections. A back plate 1 is installed at the end of the vertical section of the outrigger 5, which is then fixed to the forklift to ensure the stability of the telescopic boom.

[0027] In this embodiment, the back plate 1 is a rectangular frame structure formed by welding multiple square tubes. Multiple connection points are provided on the surface of the back plate 1 facing the forklift to achieve multi-point fixation with the forklift. Specifically, at least two hooks 2 are installed on the top of the back plate 1, and at least two latches 4 are installed on the bottom of the back plate 1. The latches 4 are connected to the back plate 1 through latch seats 3; the connection with the forklift is achieved through the hooks 2 and latches 4. It is understood that in other embodiments, the back plate 1 and the forklift can use other connection methods, such as bolt connection.

[0028] In this embodiment, the support arm 5 is also a square tube structure. The horizontal section of the support arm 5 away from the back plate 1 is provided with an inner sleeve 8, which is inserted into the support arm 5. A rod end double ear seat 9 is installed on the inner sleeve 8. A hydraulic cylinder double ear seat 7 is installed at the end of the horizontal section of the support arm 5 away from the inner sleeve 8. A first hydraulic cylinder 6 is connected between the hydraulic cylinder double ear seat 7 and the rod end double ear seat 9. The extension or retraction of the inner sleeve 8 relative to the support arm 5 is achieved by extending or retracting the first hydraulic cylinder 6, thereby realizing the horizontal adjustment of the mechanical claw 19.

[0029] The bottom of the protruding end of the inner sleeve 8 is fitted with a connecting pipe 13 via a corner flange 12. The connecting pipe 13 is vertically positioned, and the mechanical claw 19 is installed at the end of the connecting pipe 13. The length of the connecting pipe 13 is less than the length of the vertical section of the support arm 5. The shorter connecting pipe 13 allows the mechanical claw 19 to reach into the tire storage trolley's protective netting or the steel platform fence to grab the tire blank. The connecting pipe 13, the inner sleeve 8, and the L-shaped support arm 5 constitute a portal-type boom structure.

[0030] The mechanical gripper 19 is mounted to the end of the connecting pipe 13 via the first flange 15. In this embodiment, the mechanical gripper 19 adopts a lever mechanism, including multiple sets of gripper parts 190. Each gripper part 190 is evenly distributed around the second flange 17. A fulcrum is provided near the top of each gripper part 190, and it is hinged to the second flange 17 via a first pin 18. The top of each gripper part 190 is connected to a fork lever 21. The mating end of the fork lever 21 and the gripper part 190 has a U-shaped structure, which is engaged with the outside of the gripper part 190. The two are then connected via a second pin 20. The second flange 17 has a guide groove, through which the fork lever 21 passes and is hinged to the third flange 22 via a third pin 24.

[0031] The second hydraulic cylinder 14 is connected between the first flange 15 and the third flange 22, and is fixed to the bottom of the first flange 15 by bolts. Multiple connecting plates 16 are arranged around the first flange 15, positioned between adjacent claw portions 190. The connecting plates 16 connect the first flange 15 and the second flange 17. This structure enhances the connection strength of the robotic arm and protects the internal second hydraulic cylinder 14. The second hydraulic cylinder 14 extends to control the opening of the robotic claw 19, and retracts to retract each claw portion 190 to grasp the tire blank.

[0032] The connection end between the claw portion 190 and the second flange 17 has a hook-shaped structure, forming a hook-shaped force application point, which allows the second hydraulic cylinder 14 to open and close the mechanical claw 19 with a small stroke. The specific number of claw portions 190 can be determined according to the weight of the tire blank to be grasped. In this embodiment, the mechanical claw 19 includes six claw portions 190.

[0033] like Figure 1 As shown, the telescopic boom lift in this embodiment is equipped with a vehicle-mounted wireless monitoring unit. The vehicle-mounted wireless monitoring unit is wirelessly connected to the display screen, which allows observation of the status of the mechanical gripper 19 and the tire gripping situation from above. The vehicle-mounted wireless monitoring unit features full-color night vision, solar charging, wireless WIFI transmission, and magnetic attachment for wire-free operation.

[0034] In this embodiment, two vehicle-mounted wireless monitoring units are installed, namely the first vehicle-mounted wireless monitoring unit 10 and the second vehicle-mounted wireless monitoring unit 11. The first vehicle-mounted wireless monitoring unit 10 is installed on the vertical section of the support arm 5, and the second vehicle-mounted wireless monitoring unit 11 is installed on the inner sleeve 8.

[0035] like Figures 1-4 As shown, an oil passage block 23 is also installed at the extended end of the inner sleeve 8. The oil passage of the second oil cylinder 14 passes through the oil passage block 23, making the pipeline arrangement indirect. Furthermore, a throttle valve is installed on the oil passage, so that the opening and closing speed of the mechanical claw 19 is adjustable, ensuring that the embryo is not damaged during gripping.

[0036] The working principle of this embodiment is as follows: When the rod end of the second cylinder 14 extends, it drives the third flange 22 to extend. The third flange 22 drives the fork lever 21 to pull down. Under the action of the second flange 17 as a fulcrum, the mechanical claw 19 opens. The distance between the second flange 17 and the third flange 22 is lengthened, and the mechanical claw 19 changes from a closed state to an open state.

[0037] When the rod end of the second cylinder 14 retracts, it drives the third flange 22 to retract. The third flange 22 drives the fork lever 21 to lift up. Under the action of the second flange 17 as a fulcrum, the mechanical claw 19 closes. The distance between the second flange 17 and the third flange 22 is shortened, and the mechanical claw 19 changes from an open state to a closed state, realizing the gripping of the tire blank.

[0038] When the EMS conveyor line is malfunctioning or under maintenance, forklifts are needed to handle tire blanks. In this embodiment, the two-person handling and loading of tire blanks on the steel platform line and the two-person transfer and unloading of tire blanks on the storage trolley are transformed into mechanical handling. The tire blanks are picked up by mechanical claws 19, which reduces the number of personnel involved in the tire blank transfer process, improves handling efficiency and safety, and ensures production continuity.

[0039] Example 2: This embodiment provides a forklift equipped with the telescopic boom lifter described in Embodiment 1. The original hydraulic system of the forklift is adjusted to have two outputs: one for the extension and retraction of the outrigger 5 and inner sleeve 8, and the other for controlling the opening and closing of the mechanical gripper 19. This enables high-altitude gripping of tire blanks on the steel platform line and tire release from the tire storage trolley, ensuring continuous production. The forklift is equipped with a display screen that shows information such as the gripping status of the mechanical gripper, enabling real-time monitoring of the tire blank gripping process and improving gripping accuracy.

[0040] By operating the handle on the forklift, the second hydraulic cylinder 14 in the telescopic boom can be controlled. When the handle is pushed open, the rod end of the second hydraulic cylinder 14 extends; when the handle is pulled back to close, the rod end of the second hydraulic cylinder 14 retracts.

[0041] It should be noted that the forklift configuration must ensure that the maximum load / load center distance at the maximum lifting height when grabbing the tire blank does not cause the forklift to tip over.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
