Embodiment Construction

[0029] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] The invention relates to a method for installing a trolley propulsion beam guard plate, and the specific steps include:

[0031] (1) Disassemble other accessories on the trolley propulsion beam one by one, mark them in order and arrange them neatly;

[0032] (2) Install and buckle the guard plate on the advancing beam of the trolley to match it;

[0033] (3) Fixedly install the anti-retraction device at the rear end of the propulsion beam of the trolley;

[0034] (4) Fix and install the auxiliary fixing device 1 of the guard board and the top device in sequence at the front end of the propulsion beam of the trolley;

[0035] (5) Reinstall the other acces...

Abstract

The invention provides a method for mounting a berm plate of a push beam of a trolley. The method comprises steps as follows: other accessories on the push beam of the trolley are dismounted one by one, marked in sequence and then placed in order; the berm plate is mounted and buckled on the push beam of the trolley to be matched with the push beam of the trolley; a retaining device is fixedly mounted at the back end of the push beam of the trolley; an auxiliary berm plate fixing device and a tip device are sequentially and fixedly mounted at the front end of the push beam of the trolley; the dismounted accessories are mounted one by one; inspection and commissioning are performed. The improved mounting method is simple and low in cost, and faults that two ends of the push beam completely deform and warp upwards due to stress and abrasions during early rock drilling operation can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of engineering equipment, and in particular relates to a method for installing a trolley propulsion beam guard plate. Background technique [0002] The full hydraulic driving jumbo is mainly suitable for the excavation and driving of roadways, tunnels and culverts in the fields of mining, metallurgy, hydropower, railways and highways. It has the characteristics of strong mobility, high operating efficiency and easy operation. After long-term on-site operations, it was found that the trolley propulsion beam guard plate is prone to deformation and warping at the 200MM position of the front end of the propulsion beam, which affects the normal excavation operation, and it is easy to injure the operator when going up and down the drilling tools, causing safety hazards. [0003] Such as figure 1 As shown, since the trolley propulsion beam guard plate is snap-fitted on the propulsion beam, no bolts are used to fix it. Whe...
