Description

Technical Field

[0001] This utility model relates to the field of roller conveying, specifically a flexible telescopic roller conveyor that can adapt to slopes. Background Technology

[0002] Telescopic roller conveyors are widely used in logistics, warehousing, and manufacturing industries. Traditional telescopic roller conveyors rely on the horizontal deployment and retraction of a scissor-type telescopic frame, which facilitates flexible layout of various conveyor lines on flat ground. However, in sloping areas, the vertical displacement of the scissor units is restricted by the pivot joints connecting them, making it difficult for the scissor-type telescopic frame to adapt to the slope and affecting the adaptability and performance of the telescopic roller conveyor. Utility Model Content

[0003] The purpose of this utility model is to provide a flexible telescopic roller conveyor that can adapt to both upward and downward slopes, which can be arranged in sloping sites and has good applicability.

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

[0005] A flexible telescopic roller conveyor adaptable to slopes includes two sets of scissor-type telescopic frames, several H-shaped support legs, several rollers, several first pivot joints, and several second pivot joints.

[0006] The two sets of scissor-type telescopic frames are arranged at intervals between each other. Each set of scissor-type telescopic frames includes multiple scissor units arranged from left to right. Each scissor unit includes two diagonal arms arranged in a cross configuration.

[0007] The two inclined arms in each scissor lift unit are pivotally connected in the middle by the first pivot connector to form a middle pivot point. The upper and lower ends of the two inclined arms are pivotally connected to the corresponding inclined arms in the adjacent scissor lift unit by the second pivot connector to form upper pivot points and lower pivot points respectively. Several rollers are rotatably connected between the corresponding upper pivot points in the two sets of scissor lift telescopic frames.

[0008] The H-shaped outriggers are arranged at intervals along the length of the scissor-type telescopic frame, and the two sets of scissor-type telescopic frames are located between the two sides of the H-shaped outriggers.

[0009] In the two sets of scissor-type telescopic frames, the pivot points located on the left or right sides of each H-shaped leg are designed to be de-pivoted to accommodate changes in the local slope of the scissor-type telescopic frame.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. By de-pivoting the pivot point in the middle of the adjacent scissor unit on the right side of each H-type support leg, the scissor telescopic frame can be bent up and down in some areas, thereby adapting to the changes in the slope of the installation site and improving the adaptability and performance of the telescopic roller conveyor.

[0012] 2. Through the sliding fit between the sliding groove at the lower end of the connecting plate and the second pivot member, the H-type outrigger can adapt to the height changes caused by the extension of the scissor unit during the horizontal stretching or retraction of the scissor telescopic frame, thus improving the ease of use and support stability of the H-type outrigger.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0020] like Figure 1-5 The diagram shown is a schematic representation of an embodiment of a flexible telescopic roller conveyor adaptable to slopes provided by this utility model:

[0021] A flexible telescopic roller conveyor adaptable to slopes includes two sets of scissor-type telescopic frames 1, several H-shaped support legs 2, several rollers 3, several first pivot joints 4, and several second pivot joints 5.

[0022] The two sets of scissor-type telescopic frames 1 are arranged at an interval between front and back. Each set of scissor-type telescopic frames 1 includes multiple scissor units 10 arranged from left to right. Each scissor unit 10 includes two diagonal arms 101 arranged in a cross configuration.

[0023] The two inclined arms 101 in each scissor unit 10 are pivotally connected in the middle by the first pivot 4 to form a middle pivot point. The upper and lower ends of the two inclined arms 101 are pivotally connected to the corresponding inclined arms 101 in the adjacent scissor unit 10 by the second pivot 5, forming an upper pivot point and a lower pivot point respectively. Several rollers 3 are rotatably connected between the corresponding upper pivot points in the two sets of scissor telescopic frames 1.

[0024] The H-shaped support legs 2 are arranged at intervals along the length of the scissor-type telescopic frame 1, and the two sets of scissor-type telescopic frames 1 are located between the two sides of the H-shaped support legs 2.

[0025] In the two sets of scissor-type telescopic frames 1, the pivot points located on the left or right sides of each H-shaped support leg 2 are designed to be de-pivoted in order to adapt to changes in the local slope of the scissor-type telescopic frame 1.

[0026] It should be specifically noted that the H-type support leg 2 is an existing product on the market. The H-type support leg 2 can be extended and retracted to adjust the overall height of the H-type support leg 2. Both sides of the bottom of the H-type support leg 2 are equipped with casters with brakes.

[0027] Furthermore, the roller 3 can be made of rubber or stainless steel.

[0028] The upper part of the inner wall of both sides of the H-shaped support leg 2 is fixed with a connecting plate 20, and each connecting plate 20 is connected to the scissor-type telescopic frame 1 on its corresponding side.

[0029] The upper end of the connecting plate 20 is fixedly connected to the upper pivot point of the corresponding scissor-type telescopic frame 1. The lower part of the connecting plate 20 is provided with a vertically extending sliding groove 201, and the sliding groove 201 is slidably engaged with the second pivot member 5 at the corresponding lower pivot point.

[0030] Preferably, in the two sets of scissor-type telescopic frames 1, the central pivot points adjacent to each H-shaped leg 2 on the right side are designed to be de-pivoted to adapt to changes in the local slope of the scissor-type telescopic frame 1.

[0031] Preferably, both the first pivot member 4 and the second pivot member 5 are pivots with bushings sleeved on the outer side.

[0032] The installation method of this utility model is roughly as follows:

[0033] Based on the varying installation slope of the site, several H-shaped support legs 2 are first arranged sequentially and at intervals along the conveying path, with the H-shaped support legs 2 positioned on the left side of the slope change point. Then, the two sets of scissor-type telescopic frames 1 are connected to each H-shaped support leg 2 via connecting plates 20. It should be noted that when the scissor-type telescopic frame 1 is horizontally stretched or retracted, the overall height of the scissor unit changes due to the change in the extension state of each scissor unit 10. At this time, the second pivot member 5 slides adaptively within the slide groove 201. Subsequently, a de-pivot design is implemented at the middle pivot point on the adjacent right side of each H-shaped support leg 2, i.e., the first pivot member 4 in the middle of the two inclined arms 101 at this location is removed, allowing the scissor-type telescopic frame 1 to locally bend vertically, thus adapting to changes in the installation slope of the site. Finally, several rollers 3 are installed at the upper pivot points of the two scissor-type telescopic frames 1, completing the installation.

[0034] 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.
