Problems solved by technology

When the diameter and shape of the segments in the track are different, different track installation bases need to be used. At the same time, during the laying process of the track bed slab, the track needs to be assembled and disassembled continuously, making the overall construction efficiency low

Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, unless stated otherwise, the used orientation words such as "front and rear" are usually relative to the direction of the boards transported by the roller set.

[0034] Such as Figure 1-5 As shown, the present disclosure provides a pallet truck for walking on irregular roads, the pallet truck includes a frame 1, a steering mechanism 2, wheels 3, a pallet transport mechanism 4, and actively adjusts the wheels to swing up and down relative to the frame 1 Angled suspension mechanism 5 as well as two cabs.

[0035] The steering mechanism 2 includes a slewing support 21 and a steering drive member 22 . The slewing support 21 i...

Abstract

The invention relates to a suspension mechanism (5) of a board transporting vehicle. The suspension mechanism comprises a suspension frame (51), a first axle balancing arm (52a), a second axle balancing arm (52b), a first lifting driving piece (53a) and a second lifting driving piece (53b); one end of the first lifting driving piece and one end of the second lifting driving piece are correspondingly hinged to the two sides of the upper end of the suspension frame; the other end of the first lifting driving piece and the other end of the second lifting driving piece are correspondingly hinged to one end of the first axle balancing arm and one end of the second axle balancing arm; and the other end of the first axle balancing arm and the other end of the second axle balancing arm are correspondingly hinged to the two sides of the lower end of the suspension frame. A tire is driven to swing up and down through expansion and retraction of the first lifting driving piece and the second lifting driving piece so that the vehicle can adapt to arc, U-shaped or other irregular grounds and can stably run; and therefore, the erection of transporting rails in tunnels is avoided, and the construction efficiency is enhanced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular, to a suspension mechanism for a pallet truck. Background technique [0002] The construction of existing subway tunnels mostly adopts the construction technology of shield tunneling plus prefabricated segments. Before the laying of tracks and track bed slabs, the construction sections of subway tunnels are mainly arc-shaped, horseshoe-shaped and other irregular shapes. When transporting the road bed in the tunnel, the road surface that the transport vehicle touches during walking is arc-shaped or horseshoe-shaped, while the traditional engineering vehicle sets the axle to be arranged in the vertical direction, adapting to the horizontal and straight road surface, and the contact arc When the road surface is shaped or horseshoe-shaped, there will be many disadvantages such as smaller contact surface with the tire, wheel slippage, severe partial wear of the tire, and easy d...
