Problems solved by technology

[0004] The main problems of the above-mentioned mechanical device with the expressway divider guardrail as the running track are: (1) the above-mentioned models are all designed for the single wave beam guardrail of the expressway. There is no report on the design of two parallel wave beam guardrails on the central divider; (2) the above models rely on a pair of small driving pulleys or sheaves on the upper part to hook on the upper edge of the guardrail in a small area On the cross-section, the whole machine is placed obliquely on the inside of the guardrail. Due to the small contact area and the concentrated force, the whole machine is easy to derail; (3) The above-mentioned hook-and-loop design requires that its driving, walking and hooking mechanisms must be arranged obliquely Above the outer side of the guardrail, and the column on the outer side of the guardrail directly limits its installation space, which puts forward higher requirements for its miniaturization design; (4) The above-mentioned hook-and-loop design greatly limits the overall structure, load capacity, and operating speed and the amount of vibration, which indirectly limits the function and work efficiency of the whole machine

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to Figure 1~Figure 4 , the self-propelled work platform that straddles the guardrail of the central divider of the expressway includes a car body 1, a hurdle walking device, a ground wheel lifting device, a power transmission device, and a machine tool carrying device, wherein the car body 1 is driven by two pairs of upper profiling wheels 13 1. Two pairs of lower profiling wheels 12 and a pair of profiling drive wheels 7 make their whole ride on two parallel wave beam guardrails 11 of the expressway median, and the width of the car body 1 is the same as that of the two parallel wave beam guardrails 11. match the width between them.

[0025] refer to Figure 1~Figure 10 The hurdle walking device includ...

Abstract

The invention discloses a self-propelled operating platform that straddles the guardrail of the central divider of an expressway, comprising a car body, a hurdle walking device, a ground wheel lifting device, a power transmission device, and a machine carrying device, and belongs to the field of expressway maintenance machinery. Compared with the prior art, the advantages of the present invention are: (1) The present invention utilizes the central divider of the expressway as the driving space of the working machine, effectively avoiding the problem of occupying the normal driving lane of the traditional vehicle-mounted working machine; (2) ) The design of the hurdle walking device adopted in the present invention relies on the upper and lower profiling wheels to clamp the guardrail of the central divider and uses it as a running guide rail to realize two-way straddling with the help of profiling driving wheels, and the whole machine has a strong anti-derailment ability; (3) The design of the ground wheel lifting device adopted in the present invention can make the whole machine realize walking on the ground with the lower profiling wheels when necessary, and then can realize the external force dragging walking under the condition of no guardrail.

Description

technical field [0001] The invention relates to a work platform that can be attached to and straddle the wave beam guardrail of an expressway, more particularly, refers to a self-propelled work platform that straddles the guardrail of the central divider of the expressway, and belongs to the field of expressway maintenance machinery. Background technique [0002] As of the end of 2014, the total mileage of expressways in my country has reached 112,000 kilometers, surpassing the United States to rank first in the world, and there is undoubtedly a huge demand for expressway maintenance machinery supporting it. At present, highway maintenance machines with a high degree of mechanization are mostly vehicle-mounted, including hedge trimmers, guardrail cleaning machines, road sweepers, and marking machines. The carrying capacity, operating efficiency, operating quality and personnel safety of the vehicle-mounted operating machinery have been effectively improved, but there are als...
