Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 5 to Figure 10 As shown, a self-moving driving bridge for connecting the open-pit mine stope and the internal dump, including the main bridge deck top plate 1, two main bridge deck side plates 2, the lifting platform 3, and the stope side folding bridge deck 7. The first folded bridge deck 9 on the side of the dump site and the second folded bridge deck 11 on the side of the dump site. 1 The right end of the lower surface is connected to one end of the other main deck side plate 2, the front ends of the two main deck side plates 2 are connected to the first side guard plate 4, and the rear ends of the two main deck side plates 2 are connected to the second side guard plate Connected, two first hydraulic cylinders 5 are arranged between the first side guard plate 4 and the main bridge deck top plate 1, the cylinder end o...

Abstract

The invention relates to a self-moving vehicular bridge for connecting an open-pit mine stope and an inner waste dump, and belongs to the technical field of self-moving vehicular bridges. The bridge comprises a main bridge floor top plate, a main bridge floor side plate, a lifting platform, a side protecting plate, first hydraulic cylinders, supporting hydraulic cylinders, a stope side folding bridge floor, a stope side folding hydraulic cylinder, a waste dump side first folding bridge floor, a waste dump side folding hydraulic cylinder, a waste dump side second folding bridge floor, a stope first side face guard, a stope second side face guard, a third hydraulic cylinder, a waste dump first side face guard, a waste dump second side face guard, a waste dump third side face guard, a fourthhydraulic cylinder, a fifth hydraulic cylinder, a track walking mechanism and a cab, a part, which is originally formed by piling up loose earth rock, of a steel structure is changed into a whole self-moving steel structure, and secondary stripping does not need to be carried out on the part of the steel structure during coal pressing under a subsequent mining structure. Due to the fact that the vehicular bridge needs to be moved and erected repeatedly, the secondary stripping cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of self-moving driving bridges, and in particular relates to a self-moving driving bridge for connecting an open-pit mine stope and an internal dump. Background technique [0002] In order to solve the problem of increasing the internal discharge distance caused by the excessively long working line when the internal dump of the near-level open-pit mine adopts tracking mining, most of the near-level open-pit mines use an earth-stone bridge between the stope and the internal dump. A solution to reduce transport distances. See the attached schematic diagram of the scheme figure 1 , see the attached step profile figure 2 . The accumulation angle of the earth-rock discharge bridge is the natural repose angle of loose materials, which is 33°, the slope angle on the side of the stope is taken as the slope angle of the coal step, and 70° is taken, and the slope angle of the loose material step is taken on the si...
