Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to an unpowered roller conveyor. Background Art

[0002] Unpowered roller conveyors are commonly used in material handling, relying on gravity or manual propulsion to transport items. Their simple structure, consisting primarily of rollers, a frame, and support legs, allows for efficient cargo transfer and sorting, and is widely used in warehousing, cold chain logistics, and production lines. Because they operate without electricity, they save energy and reduce maintenance costs, making them environmentally friendly and economical conveying equipment.

[0003] The four supporting legs of the existing unpowered roller conveyor are set at a fixed height. Therefore, when used in an uneven location, the supporting legs are easily left in the air, making the overall conveyor installation unstable, which makes it inconvenient to support the conveyor on uneven ground, making the unpowered roller conveyor less applicable. For this reason, we propose an unpowered roller conveyor. Utility Model Content

[0004] The purpose of the utility model is to provide a non-powered roller conveyor to solve the problem that the conveyor proposed in the above background technology is not convenient for supporting and using on uneven ground.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-powered roller conveyor, comprising an external frame, a sliding frame slidably connected to the internal part of the external frame, a roller rotatably connected to the side wall of the sliding frame, a slide rail fixed to the side wall of the external frame, a sliding member slidingly matched to the outside of the slide rail, a support column fixed to the bottom of the sliding member, a locking bolt provided on the side wall of the sliding member, an anti-slip pad provided on the bottom of the support column, a support member fixed to the bottom of the external frame, a sliding column slidably matched to the internal part of the support member, a pressure plate fixed to the front side wall of the sliding column, a locking knob matched to the support member provided on the side wall of the sliding column, a telescopic rod embedded in the bottom of the sliding column, and an extension column fixed to the bottom of the telescopic rod.

[0006] Preferably, a connecting rod is fixedly connected to the side wall of the sliding frame, and an outer wall of the connecting rod is provided with an external thread.

[0007] Preferably, a connecting cylinder matched with the external thread is provided on the outside of the connecting rod, and the connecting rod is matched with the side wall of the roller.

[0008] Preferably, a locking pin that cooperates with the sliding frame is provided on the top of the external frame, and a pin hole is opened on the top of the sliding frame.

[0009] Preferably, a plurality of mounting holes are provided on the side wall of the sliding frame, and bearings are provided inside the mounting holes.

[0010] Preferably, a sliding hole is provided on the side wall of the support member, and the locking knob is fitted into the side wall of the sliding hole.

[0011] Preferably, a pad is provided at the bottom of the extension column, and the extension column is matched with the bottom of the sliding column.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model supports the unpowered roller conveyor with support columns, and then pushes the external frame back and forth under the support of the support columns and locks it with locking bolts. Then, the pressure plates of the four support members can be slid up and down to make the sliding columns move downward and contact the ground to support the top external frame. After the support columns are used for pre-support, the external frame can be slid to adjust the position of the support members. In combination with the four telescopically adjustable support members, it can be used for support on uneven sites, thereby improving the applicability of the unpowered roller conveyor.

[0014] 2. When the roller needs to be replaced, the pin can be pulled out, and then the sliding frame can be pulled out of the outer frame as a whole. Then, the connecting tube is turned so that the connecting tube is rotated to the outside of the connecting rod at one end. At this time, the sliding frames on both sides are separated, so that all the rollers are unlocked and disassembled. Then, when the roller is deformed or damaged, it can be conveniently disassembled and replaced, eliminating the trouble of turning multiple bolts and saving manpower.

A telescopic rod 152 is embedded in the bottom of the sliding column 141. The telescopic rod 152 uses a common electric push rod on the market. The electric push rod is usually composed of a motor, a transmission system, and a push rod. The working principle of the electric push rod is to drive the transmission system through the motor to make the push rod run in a straight line. When the sliding column 141 slides to the end and the extension column 150 cannot touch the ground for support, the telescopic rod 152 can continue to be controlled to make the extension column 150 continue to extend. The push rod structure at the bottom of the telescopic rod 152 is fixed to the extension column 150 by bolts.

[0023] Specifically, a connecting rod 112 is fixed to the side wall of the sliding frame 110, and the ends of the connecting rods 112 of the front and rear opposing sliding frames 110 are in contact and in the same straight line. When the connecting tube 113 is rotated to the outside of the ends of the two connecting rods 112, the two connecting rods 112 can be locked and connected. When the connecting tube 113 cooperates with the external thread 114 to rotate toward the outside of one of the connecting rods 112 and away from the other connecting rod 112, the two connecting rods 112 are unlocked, thereby unlocking the two opposing sliding frames 110. The outer wall of the connecting rod 112 is provided with an external thread 114.

[0024] Furthermore, a connecting tube 113 is provided on the outside of the connecting rod 112 to be matched with the external thread 114 , and the connecting rod 112 is matched with the side wall of the roller 111 .
