[0002] A hoist is a device that lifts a bucket to a designated position on the equipment. It typically includes a support frame, a hydraulic lifting device, and a lifting seat. The hydraulic lifting device is located at the bottom of the support frame, and the lifting seat moves vertically along the support frame and is raised and lowered under the drive of the hydraulic lifting device.

[0003] Some elevators have conveyor lines on their lifting parts to facilitate the delivery of goods. For example, Chinese Patent Publication No. CN207827131U discloses "an elevator" that does not require a column, has a compact structure, small size, and low manufacturing cost. It directly connects to the infeed / outfeed conveyor line on the lifting seat to realize the transfer of goods, and then drives the lifting seat to move up and down to realize the lifting of goods. The structure is simple and easy to implement.

[0004] However, in actual use, the conveyor line of the lifting frame inevitably experiences slight vibrations during the lifting process, which can easily cause products to fall off the conveyor line and affect the performance of the lifting machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the slight vibration that occurs during the lifting process of the conveyor line, which can easily cause products to fall off the conveyor line. Therefore, this invention proposes a lifting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a hoist, including a housing, a mounting frame on the housing, a lifting frame on the housing, a lifting device on the mounting frame that cooperates with the lifting frame, a plurality of rollers rotatably mounted on the lifting frame, the rollers being connected by a belt, and a drive motor that cooperates with the rollers mounted on the lifting frame;

[0008] The lifting frame is equipped with two protective structures, which are positioned opposite each other at both ends of the roller to form a material guiding channel.

[0009] Furthermore, the protective structure includes a support, a mounting plate, and a guardrail, with the support connected to the lifting frame via fasteners.

[0010] Furthermore, the mounting clamp is connected to the support part through a connecting assembly, and the mounting clamp is provided with a connecting frame that is fixedly connected to the guardrail.

[0011] Furthermore, the connecting component includes a guide groove formed on the mounting plate, and a positioning block corresponding to the guide groove is fixedly disposed on the support portion.

[0012] Furthermore, a through groove is provided on the guide groove, and a threaded post corresponding to the through groove is fixedly provided on the positioning block. A hand-tightening nut that abuts against the mounting clamp is threaded onto the threaded post.

[0013] Furthermore, guide blocks are installed on both sides of the lifting frame, and guide rails corresponding to the guide blocks are installed on the inner wall of the outer shell.

[0014] The lifting machine proposed in this utility model has the following advantages:

[0015] In this utility model, by setting two protective structures opposite each other on the lifting frame to form a material guiding channel, the products on the lifting frame are provided with auxiliary protection to prevent the products from falling due to vibration when the lifting frame moves up and down, thereby increasing safety.

[0016] Secondly, in this utility model, the position of the mounting plate and guardrail can be adjusted by setting the connecting components to protect different models of products. At the same time, guide blocks are installed on both sides of the lifting frame, and guide rails corresponding to the guide blocks are installed on the inner wall of the outer shell to increase the stability of the lifting frame when it moves.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A hoist includes a housing 1, a mounting frame 2 on the housing 1, a lifting frame 3 on the housing 1, a lifting device 4 on the mounting frame 2 that cooperates with the lifting frame 3, a plurality of rollers 5 rotatably mounted on the lifting frame 3, the rollers 5 being connected by a belt, and a drive motor that cooperates with the rollers 5 mounted on the lifting frame 3.

[0024] The lifting frame 3 is equipped with two protective structures 6, which are positioned opposite each other at both ends of the roller 5 to form a material guiding channel.

[0025] In this utility model, two protective structures 6 are arranged opposite to each other on the lifting frame 3 to form a material guiding channel. The product is placed in the material guiding channel to provide auxiliary protection for the product and prevent the product from falling due to vibration when the lifting frame 3 moves up and down, thereby increasing safety.

[0026] Furthermore, in this embodiment, the protective structure 6 includes a support part 61, a mounting plate 62, and a guardrail 63. The support part 61 is connected to the lifting frame 3 by fasteners, preferably screws. The support part 61 has a C-shaped structure, with its lower end connected to the lifting frame 3 and its upper end connected to the mounting plate 62.

[0027] Furthermore, in this embodiment, the mounting clamp 62 is connected to the support part 61 through the connecting component 64. The mounting clamp 62 is provided with a connecting frame that is fixedly connected to the guardrail 63. The connecting frame is used to connect with the guardrail 63 and fix the guardrail 63. The guardrail 63 has a cylindrical structure, which reduces the friction caused by contact between some products and the guardrail 63.

[0028] It should be noted that in this embodiment, the connecting component 64 includes a guide groove 641 formed on the mounting clamp 62, and a positioning block 642 corresponding to the guide groove 641 is fixedly provided on the support part 61. The guide groove 641 and the positioning block 642 cooperate to restrict the movement trajectory of the mounting clamp 62 and prevent the two guardrails 63 from being non-parallel.

[0029] Furthermore, in this embodiment, a through groove 643 is provided on the guide groove 641, and a threaded post corresponding to the through groove 643 is fixedly provided on the positioning block 642. A hand-tightening nut 644 that abuts against the mounting clamp 62 is threadedly connected to the threaded post. The threaded post passes through the through groove 643 and extends above it. The hand-tightening nut 644 is located above the through groove 643 and the mounting clamp 62, abutting against the mounting clamp 62 to fix the position of the mounting clamp 62 and the guardrail 63, preventing the mounting clamp 62 and the guardrail 63 from moving and changing their position.

[0030] More specifically, in this embodiment, guide blocks 31 are installed on both sides of the lifting frame 3, and guide rails 32 corresponding to the guide blocks 31 are installed on the inner wall of the outer shell 1. By cooperating with the guide blocks 31 and the guide rails 32, the stability of the lifting frame 3 when moving is increased, the vibration amplitude is reduced, and the product is further prevented from falling.

[0031] Working method: During operation, the guide block 31 cooperates with the guide rail 32 to increase the stability of the lifting frame 3 when it moves, reduce the vibration amplitude and prevent the product from falling. The two protective structures 6 on the lifting frame 3 form a material guide channel. The product is placed in the material guide channel to provide auxiliary protection for the product. The guide groove 641 and the positioning block 642 cooperate to restrict the movement trajectory of the mounting clamp 62 and prevent the two guardrails 63 from being non-parallel. The screw nut 644 is located above the through groove 643 and the mounting clamp 62, and abuts against the mounting clamp 62 to fix the position of the mounting clamp 62 and the guardrail 63.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
