Description

Technical Field

[0001] This invention relates to a telescopic pedal for a paver, belonging to the technical field of engineering machinery pavers. Background Technology

[0002] Due to its functional requirements, the screed area of ​​the paver is quite high, requiring workers to take large steps to reach the top. Furthermore, in various environments, the paver's screed is raised, increasing the distance between the top and the ground, making it even more difficult for users to climb onto it. All these factors make the working environment unsafe, especially as climbing while the paver is in motion increases the risk of falls.

[0003] Currently, the common solution for pavers is to add a fixed step to the lower part of the screed. However, the larger the paver, the higher the fixed step becomes, which also leads to the problem of users taking too large steps when boarding the machine, making operation difficult.

[0004] The current ironing board design is somewhat limited, making it difficult to modify the existing structure. We could try to improve the boarding experience for staff by focusing on the ironing board's accessories. Summary of the Invention

[0005] The purpose of this invention is to provide a telescopic footboard for a paver, which solves the problem of adding a fixed footboard to the lower part of the screed in the prior art. However, as the paver grows larger, the height of the fixed footboard also increases, which also results in the drawback of the user taking too large a step when boarding the machine, making operation difficult.

[0006] A telescopic pedal for a paver, comprising:

[0007] A suspension assembly, the suspension assembly including a top assembly, the top assembly having two parallel waist-shaped grooves on each side, and a first limiting hole at the end of the two waist-shaped grooves;

[0008] A connecting assembly includes a connecting rod that connects to the waist-shaped grooves on both sides of the top assembly. The bottom of the connecting rod is connected to a pedal assembly. The side of the pedal assembly is provided with a second limiting hole. When the first limiting hole and the second limiting hole are aligned, they are limited by a plug pin.

[0009] A support shaft for supporting the connecting component is provided between the two sides of the suspension assembly.

[0010] Furthermore, a limiting rod is provided between the connecting rods.

[0011] Furthermore, a foot pedal axle is provided at the bottom between the connecting rods.

[0012] Furthermore, the pedal assembly is provided with a handle.

[0013] Furthermore, the top component has a threaded hole at its top for connection with the ironing plate.

[0014] Furthermore, the bottom of the connecting rod is hinged to the pedal assembly.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention adopts a telescopic pedal design, which reduces the user's boarding height, optimizes the operating experience, and thus improves the comfort of human-machine operation.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, a telescopic pedal for a paver is disclosed, comprising:

[0025] The suspension assembly 2 includes a top assembly 21, on each side of the top assembly 21 there are two parallel waist-shaped grooves 24, and a first limiting hole 23 is provided at the end of the two waist-shaped grooves 24; the top of the top assembly 21 is provided with a threaded hole for connecting to the ironing board.

[0026] The connecting assembly 3 includes a connecting rod 32 connected to the waist-shaped grooves 24 on both sides of the top assembly 21. The bottom of the connecting rod 32 is connected to a pedal assembly 4, which has a handle. The bottom of the connecting rod 32 is hinged to the pedal assembly 4. The side of the pedal assembly 4 has a second limiting hole 41. When the first limiting hole 23 is aligned with the second limiting hole 41, it is limited by a plug pin 1. A support shaft 22 for supporting the connecting assembly 3 is provided between the two sides of the suspension assembly 2.

[0027] In this embodiment, a limiting rod 31 is provided between the connecting rods 32. Due to the presence of the limiting rod 31, the connecting rods 32 are always parallel, thus avoiding stroke error.

[0028] like Figures 5-6 As shown, when the pedal assembly 4 is retracted, the plug pin 1 acts as a limit, passing through the first limit hole 23 on the suspension assembly 2 and the second limit hole 41 on the pedal assembly 4, and the three are connected.

[0029] When the insertion pin 1 rotates and extends out of the limiting hole, the pedal assembly 4 can move forward and backward without restriction. The connecting assembly 3 moves linearly along the waist-shaped groove 24. When the connecting assembly 3 slides to the end of the waist-shaped groove 24, the limiting rod 31 no longer works with the suspension assembly 2 to limit the upper and lower positions of the connecting rod 32, and the connecting rod 32 can be adjusted up and down. Due to the presence of the limiting rod 31, the connecting rod 32 remains parallel, avoiding stroke error.

[0030] When lowered to its lowest position, the support shaft 22 supports the connecting assembly 3, bearing most of the pressure and also acting as a limiter, thus fixing the overall shape of the telescopic pedal. Finally, the pedal shaft 33 and the pedal assembly 4 together form the user area. The extension of the telescopic pedal is completed; the retraction is achieved by simply reversing the operation.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
