DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 The utility model is further described in detail.

[0024] A heavy-duty fork lift transfer machine, such as Figure 1-4 As shown, this embodiment includes a main frame 1, a lifting frame 2, a telescopic fork 3, a driving member 4, a rack 5, a driving gear 6, and a guide rail 7.

[0025] The main frame 1 is provided with four guide rails 7 on its inner side. The lengths of each guide rail 7 are parallel and perpendicular to the horizontal plane. The lifting frame 2 is located inside the main frame 1. Sliders 8 are mounted on the lifting frame 2 at locations corresponding to each guide rail 7. Each slide 8 is slidably connected to its corresponding guide rail 7. The housing of the driver 4 is mounted on the main frame 1. A drive gear 6 is mounted on the driving end of the driver 4. A rack 5 is vertically mounted on the lifting frame 2 and meshes with the drive gear 6. The telescopic fork 3 is mounted on the top of the lifting frame 2. In this embodiment, the driver 4 is a commercially available product, such as a commercially available reduction motor. Alternatively, the driver 4 can be replaced by an integrated motor and reduction gear assembly. The telescopic fork 3 in this embodiment also utilizes a conventional heavy-duty telescopic fork structure suitable for heavy-duty applications. The telescopic fork 3 in this embodiment is divided into two symmetrical left and right sections. The driver 4 and the telescopic fork 3 are each controlled by an external controller. In this embodiment, the telescopic fork 3 extends forward and retracts backward.

[0026] The telescopic fork 3 is used to directly move the cargo or the pallet carrying it horizontally. The driver 4, via the drive gear 6, drives the lifting frame 2, equipped with the rack 5, to move it up and down. The guide rails 7 provide vertical guidance for the lifting frame 2, which in turn drives the telescopic fork 3, the pallet, and cargo it carries, to move upward and downward. The lifting mechanism comprised of the driver 4, drive gear 6, rack 5, and guide rails 7 boasts a greater load capacity and a longer lifting range than conventional lifting mechanisms used in lift transfer machines, making it more suitable for heavy-duty applications and providing a safe and reliable structure.

[0027] Specifically, in this embodiment, the main frame 1 includes two connected guide rail mounting brackets 101 and two side mounting brackets 102. The two guide rail mounting brackets 101 are positioned in a front-to-back relationship, while the two side mounting brackets 102 are positioned in a left-to-right relationship. The front end of each side mounting bracket 102 is bolted to the front guide rail mounting bracket 101, and the rear end of each side mounting bracket 102 is bolted to the rear guide rail mounting bracket 101. In this embodiment, the main frame 1 formed by the two guide rail mounting brackets 101 and the two side mounting brackets 102 is a rectangular parallelepiped frame structure, and the lifting frame 2 also has a corresponding rectangular parallelepiped frame structure.

[0028] In this embodiment, two symmetrical guide rails 7 are mounted on each guide rail mounting bracket 101 via screws. The positions of the guide rails 7 on the front guide rail mounting bracket 101 correspond to the positions of the guide rails 7 on the rear guide rail mounting bracket 101, respectively, so that the lifting frame 2 is subjected to uniform force and the lifting is more stable. Each guide rail 7 is located inside the main frame 1 formed by the two guide rail mounting brackets 101 and the two side mounting brackets 102. By providing a connecting portion for mounting the guide rail 7 on each guide rail mounting bracket 101 and connecting it to the guide rail 7, and then bolting the two guide rail mounting brackets 101 to the two side mounting brackets 102, the problem of the inability to process the connecting surface of an integrated frame can be effectively solved, ensuring the stable installation of the guide rails 7 on the main frame 1. In this embodiment, four lifting rings 11 are evenly arranged on the top surface of the main frame 1, with two on each guide rail mounting bracket 101, to facilitate the lifting and transfer of the entire equipment.

[0029] Specifically, in this embodiment, a driver mounting seat 9 is provided on the guide rail fixing frame 101 located on the front side by bolts, and the outer shell of the driver 4 is installed on the driver mounting seat 9 by bolts. The axial center line of the driving end of the driver 4 and the axial center line of the driving gear 6 are both parallel to the horizontal plane, and the structure of the driver mounting seat 9 itself adopts the existing technology.

[0030] In this embodiment, the front side of the lifting frame 2 is provided with two symmetrical inspection pin insertion holes 201, each for receiving a respective inspection pin 10. The axial centerlines of all inspection pin insertion holes 201 are parallel to the extension and retraction direction of the telescopic forks 3. The extension and retraction direction of the telescopic forks 3 and the axial centerlines of all inspection pin insertion holes 201 are parallel to the horizontal plane. When maintenance is required, one end of each inspection pin 10 is inserted into the corresponding inspection pin insertion hole 201, and the other end of each inspection pin 10 is overlapped on the top surface of the main frame 1. This allows the lifting frame 2 to be supported to a certain height by the inspection pins 10, making it easier for maintenance personnel to pass through the main frame 1 and the lifting frame 2 and enter the interior of the lifting frame 2 to perform maintenance and repairs on the telescopic forks 3. This ensures internal operating space and safety, and prevents the lifting frame 2 from falling during maintenance. When the jacking and transferring machine is operating normally, the inspection pins 10 are removed from the inspection pin insertion holes 201. In this embodiment, the driving member 4 and the inspection pin 10 are both located at the front side of the main frame 1, which also facilitates maintenance personnel to perform maintenance operations in a unified manner.
