The invention discloses a railway vehicle body chassis structure. The railway vehicle body chassis structure soles the problems that the giant torque force is caused due to the fact that a front-arrangement type vehicle hook mounting hole is formed in the side face of a vertical plate of a traction beam, and no operation space exists for mounting a steering frame traction base. The railway vehicle body chassis structure comprises two chassis edge beams, a chassis end beam and a sleeper beam arranged between the two chassis edge beams, a traction beam, a vehicle hook mounting sectional material and a traction guide beam are arranged between the sleeper beam and the chassis end beam, the traction beam is fixed between the sleeper beam and the vehicle hook mounting sectional material, and the traction guide beam is fixed between the vehicle hook mounting sectional material and the chassis end beam. Traction wing plates are fixedly arranged on the two sides of the vehicle hook mounting sectional material, the traction wing plates are fixedly connected with the chassis edge beams on the corresponding sides, and a jumper box is arranged between the traction wing plates and the traction guide beam. The problems are completely solved by optimizing the structures of vehicle hook mounting sectional material, the traction beam and other components, and the high-intensity performance that a vehicle body can bear 1000 kN of compression loads is kept.

The invention discloses a disc drawer used in an optical disc library, which comprises a casing and a linked first claw and a second claw arranged on the casing, and the claws of the two claws located on one side of the casing are The hooks form a set of drawer claws, and the two claw hooks on the other side of the housing form another set of drawer claws. When one set of drawer claws closes inward, the other set of drawer claws opens outward. The invention also discloses an optical disc library. When the disc tray in the disc case is completely drawn out by one set of drawer claws of the disc drawer, another set of drawer claws can enter the unlocking hole of the disc case facing the set of drawer claws. The invention only needs two claws to unlock the disc boxes on both sides, and has a simple structure. The present invention creatively uses the space in the disc box to accommodate the jaws of the disc drawer, thereby more effectively utilizing the space in the disc library, and skillfully solves the problem that the space of the disc library is too narrow to accommodate the double-sided drawer.

Provided a starting device for a vehicular power unit arranged on the opposite side of a drive wheel shaft sandwiching a crankshaft for outputting rotational driving force to a transmission device. The power unit 6 has an engine 19 loaded on a three-wheeled motorcycle 1 for outputting rotational driving force from the crankshaft 26 arranged in parallel to a rear wheel shaft 33 with rear wheels 4L,4R connected thereto, and a transmission 37 for transmitting the rotational driving force of the crankshaft 26 via a counter shaft arranged in parallel to the rear wheel shaft 33. The power unit 6 isstructured by a kick shaft 49 arranged in parallel to the crankshaft 26, a kick arm 50 arranged at the tip end of the kick shaft 49, and a kick starting mechanism 28 for starting the engine 19 by rotating the kick shaft 49 by making the kick arm 50 kick and transmitting the rotation to the crankshaft 26. The kick shaft 49 sandwiches the crankshaft 26 and is arranged on the opposite side of the rear wheel shaft 33.

The invention discloses a method for reinforcing unloading beams of an unloading station of a coal mine. The method includes technological steps of (1), chiseling away concrete of redundant portions of inner sides of the unloading beams A and B; (2), increasing widths of reinforced concrete beams of outer sides of the unloading beams; (3), welding anchor bars on steel plates which have thicknesses ranging from 8mm to 12mm and are used as formworks, and then anchoring the steel plates on the inner sides of the unloading beams; (4), grouting and compacting high-strength non-shrinkage grouting materials in gaps among the steel plates and the unloading beams; (5), additionally arranging concealed beams on an access slope between the unloading beams to prevent the unloading beams from continuing deforming inwardly after the unloading beams are reinforced; and (6), grooving parts among the unloading beams and a concrete slab of the top of a coal bunker. The method has the advantages that the method is simple in implementation process, easy to implement, short in period, and low in cost, and becomes effectively quickly, the deformation resistance and the bearing capacity of the unloading beams can be effectively improved, service lives of the unloading beams of the coal bunker are prolonged, safe running of production of the coal mine is guaranteed, and problems that unloading beams deform and tramcars cannot run through due to deformation of an unloading chamber are effectively solved.

The invention discloses a central beam assembly applicable to a railway wagon having a large weight-concentrating capability. The central beam assembly is characterized by comprising two abdominal central beams made of H-type steel, wherein an inner interval of two web plates of the central beams is 400-600mm; the web plates are connected through a central beam separating plate; the height of an abdominal part of each of the central beams is above 700mm and is gradually reduced toward two ends; inner towing beams shaped like a Chinese character 'ji' are nested between the web plates at two ends of the central beams; and the inner interval of the inner towing beams is 350mm. According to the invention, the two abdominal central beams made of H-type steel and the nested hat-shaped inner towing beams are installed and welded into a nested double-web plate central beam structure, the interval of web plates of the two abdominal central beams can be increased to 400-600mm, the effect of using large-size structural steel with wider winged edges as the central beams is realized, and an operation space for welding the central beam separating plate is ensured; and through installing and welding of large-size structural steel central beams, the central beams can achieve higher stiffness and strength and are applicable to the railway wagon having a 80t or 90t weight-concentrating capability. The nested hat-shaped inner towing beams are used for realizing mounting and barffing of a 350mm wagon coupler buffering device.

Disclosed is a confluence regulation and storage type deep tunnel constructed through a rectangle-like shield machine. The confluence regulation and storage type deep tunnel constructed through the rectangle-like shield machine is excavated through the rectangle-like shield machine and formed in a lining mode. The bin wall of the deep tunnel has a rectangle-like section. A rainwater bin and a sewage bin are arranged on the left side and the right side correspondingly and each have a round or square-like section, preferably the square-like section. Water bin abutments are arranged on the lower portions of the rainwater bin and the sewage bin, a vehicle traveling overhaul passage is arranged between the rainwater bin and the sewage bin, and pedestrian overhaul passages are arranged on two sides correspondingly. The confluence regulation and storage type deep tunnel constructed through the rectangle-like shield machine has the beneficial effects that rainwater and sewage are effectively separated, water pollution is prevented to the maximum extent, an efficient, reliable and safe repair system and repair space are guaranteed, and the space utilization rate is improved.
