Description

Technical Field

[0001] This utility model relates to an elevator, and more specifically to an elevator with a double-speed chain. Background Technology

[0002] A lifting platform is a vertical transportation device, commonly used in construction, warehouses, mines, and other places for moving people or goods up and down. For example, according to publication number CN212291803U, this utility model uses a lifting cylinder to drive the lifting assembly and the conveying assembly to move up and down along an auxiliary guide rail to achieve the lifting function of the workpiece. The conveying assembly uses a reducer to drive the end power shaft to synchronously drive the conveying chains on both sides to achieve the forward and backward translation function of the workpiece. This utility model uses a conveyor belt as the transportation method, which cannot transport heavy objects. Utility Model Content

[0003] The purpose of this invention is to provide a double-speed chain elevator that uses rollers instead of conveyor belts to increase load-bearing capacity.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A lifting platform with a double-speed chain includes a device support, a transport mechanism slidably connected to the device support, and a lifting mechanism for lifting the transport mechanism fixedly connected to the device support.

[0006] The transport mechanism includes a transport support, on which multiple rollers are rotatably connected. The transport support is slidably connected to the device support, and the multiple rollers are connected by transmission. One of the rollers is set as an electric roller with a built-in motor.

[0007] Two drive sprockets are fixedly connected to the side of the roller, and two adjacent rollers are connected by drive sprockets and chains.

[0008] The lifting mechanism includes a cylinder, which is fixedly connected to the device support. A lifting sprocket is rotatably connected to the telescopic end of the cylinder. A chain is connected to the lifting sprocket. One end of the chain is fixedly connected to the device support, and the other end of the chain is fixedly connected to the transport support.

[0009] The transport vehicle is equipped with a pallet;

[0010] Two straightening mechanisms are fixedly connected to the transport mechanism;

[0011] The transport mechanism includes a base plate, which is fixedly connected to the transport support.

[0012] Multiple threaded cylinders are fixedly connected to the base plate, and each threaded cylinder is fitted with a centering wheel with clearance.

[0013] The threaded cylinder is connected to an adjusting pin by a thread. A shim is provided at the bottom of the adjusting pin and on the straightening wheel. A compression spring is provided between the two shims.

[0014] The centering wheel is made of nylon.

[0015] The beneficial effects of this utility model are as follows:

[0016] Rollers are used instead of conveyor belts to increase load-bearing capacity; two straightening mechanisms can effectively straighten the pallet and prevent it from tilting during transport due to improper positioning when it enters the transport mechanism. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown below, the structure and function of a double-speed chain elevator will be described in detail.

[0028] A lifting platform with a double-speed chain includes a device support 1, a transport mechanism 2 slidably connected to the device support 1, and a lifting mechanism 3 for lifting the transport mechanism 2 fixedly connected to the device support 1.

[0029] In use, the pallet 5 is transported by the transport mechanism 2, and the transport mechanism 2 is raised and lowered by the lifting mechanism 3, thereby completing the lateral and vertical transport of the pallet 5.

[0030] The transport mechanism 2 includes a transport support 21, on which multiple rollers 22 are rotatably connected via bearing seats. The transport support 21 is slidably connected to the device support 1 via sliders and slide rails. The multiple rollers 22 are connected by transmission. Two transmission sprockets 23 are fixedly connected to the side of each roller 22. Adjacent rollers 22 are connected by transmission sprockets 23 and chains. Figure 4 As shown, one of the rollers 22 is configured as an electric roller with a built-in motor;

[0031] When one roller 22 is driven to rotate, it will drive another roller 22 to rotate. Through the transmission of the chain and the drive sprocket 23, the common rotation of multiple rollers 22 is completed. The pallet 5 is placed on multiple rollers 22. Through the rotation of multiple rollers 22, the lateral transportation of the pallet 5 is completed.

[0032] The lifting mechanism 3 includes a cylinder 31, which is fixedly connected to the device bracket 1 by screws. A lifting sprocket 32 ​​is rotatably connected to the telescopic end of the cylinder 31 by a bearing with a seat. A chain 33 is connected to the lifting sprocket 32. One end of the chain 33 is fixedly connected to the device bracket 1 by screws, and the other end of the chain 33 is fixedly connected to the transport bracket 21 by screws.

[0033] When cylinder 31 is activated, the extension and retraction end of cylinder 31 drives the lifting sprocket 32 ​​to move up and down. The lifting sprocket 32 ​​forms a movable pulley structure, which causes cylinder 31 to move up and down by S, and the lifting plate to move up and down by 2S, achieving a 2 times displacement, realizing the up and down transportation of pallet 5. The pallet 5 can be used to place objects that need to be transported.

[0034] Furthermore, such as Figures 5 to 7 As shown, in order to ensure that the pallet 5 can be transported upright on the transport mechanism 2, two uprighting mechanisms 4 are fixedly connected to the transport mechanism 2;

[0035] The transport mechanism 2 includes a base plate 41, which is fixedly connected to the transport bracket 21 by screws. Multiple threaded cylinders 42 are welded on the base plate 41. Each threaded cylinder 42 is fitted with a straightening wheel 43 with clearance. The straightening wheel 43 is made of nylon material and provides self-lubrication for the rotation of the straightening wheel 43. Adjusting pins 44 are threadedly connected to the threaded cylinders 42. Washers 45 are provided at the bottom of the adjusting pins 44 and on the straightening wheel 43. A compression spring is provided between the two washers 45.

[0036] The centering wheel 43 has a conical structure. The diameter of the lower end of the centering wheel 43 is smaller than the diameter of the upper end of the centering wheel 43. The side of the centering wheel 43 contacts the side of the pallet 5. When the pallet 5 is transported on multiple rollers 22, the side of the pallet 5 will push the centering wheel 43 to move upward on the threaded cylinder 42. The conical side of the centering wheel 43 limits the side of the pallet 5 to ensure the transport position of the pallet 5.

[0037] Furthermore, in actual use, the pallet 5 may be damaged when it hits the edge of the device support 1 due to the roller 22's inability to stop in time during transport. To prevent damage to the pallet 5, the adjusting pin 44 is rotated, causing it to move on the threaded cylinder 42 through the thread. The adjusting pin 44 compresses the compression spring through the washer 45, and the compression spring compresses the straightening wheel 43. This adjusts the pressure of the straightening wheel 43 on the pallet 5, with the compression spring on the front straightening wheel 43 having a smaller pressure and the compression spring on the rear straightening wheel 43 having a larger pressure, creating damping. As the pallet 5 is transported from front to back, the compressive force of the straightening wheel 43 gradually increases, reducing the risk of the pallet 5 colliding with the device support 1.
