Problems solved by technology

[0002] The chiseling of prefabricated hollow slab web concrete for bridges is currently usually done manually, and the construction efficiency is low. Roughness, depth, and exposure are difficult to meet the requirements; in addition, from the perspective of occupational health, the dust caused by manual chiseling seriously endangers the physical and mental health of workers
Therefore, the chiseling method generally has problems such as difficulty in ensuring the quality of the workmanship, low chiseling efficiency, and serious harm to the human body.
[0003] So far, there is no device that can overcome the above defects

Embodiment Construction

[0033] A kind of equipment for automatic roughening of bridge prefabricated hollow slab web concrete, such as figure 1 and 2 As shown: it includes a carrying frame 2 driven by a walking device. The bottom of the carrying frame 2 is provided with a positioning wheel 3. On both sides of the carrying frame 2, there are two small steel wheels 8 that are controlled by the control device along the above-mentioned carrying frame. 2 The chiseling device can move vertically up and down on both sides, and the control device is driven by a power device;

[0034] The carrying frame 2 is welded by two different types of channel steel, and four positioning wheels 3 are respectively installed at the ends of the channel steel on both sides of the left and right sides of the carrying frame 2;

[0035] like Figure 5 and 6 Shown: the chisel device includes a chisel bracket 7 fitted on a small steel wheel 8, a chisel 4 with a chisel head 5 is fixed on the bracket 7, and at the end of the chis...

Abstract

The invention relates to concrete chiseling equipment and an application method thereof, in particular to automatic concrete chiseling equipment of a prefabricated bridge hollow slab web and a construction method. The equipment is characterized by comprising a bearing frame driven by a walking device; a positioning wheel is arranged at the bottom of the bearing frame; two sides of the bearing frame are provided with two chiseling devices through small steel wheels in a matched manner; the chiseling devices are controlled by a control device, and can vertically move up and down along two sides of the bearing frame; and the control device is driven by a power device. The device is simple in structure, low in construction cost, convenient to use, reliable in performance, convenient to install and dissemble, flexible in use, high in controllability and adaptability and widely popularized and applied in actual construction. The invention further provides the construction method of the automatic concrete chiseling equipment of the prefabricated bridge hollow slab web.

Description

technical field [0001] The invention relates to a concrete chipping device and a method for using the same, in particular to an automatic chipping device and a construction method for bridge prefabricated hollow slab web concrete. Background technique [0002] The chiseling of prefabricated hollow slab web concrete for bridges is currently usually done manually, and the construction efficiency is low. The roughness, depth, and exposure are difficult to meet the requirements; in addition, from the perspective of occupational health, the dust caused by manual chiseling seriously endangers the physical and mental health of workers. Therefore, the ubiquitous problems of the chiseling method are that the process quality is difficult to guarantee, the chiseling efficiency is low, and the human body is seriously injured. [0003] So far, there is no device capable of overcoming the above drawbacks. Contents of the invention [0004] The purpose of the present invention is to ov...
