Abstract

The utility model relates to an auxiliary transportation device of a coal mine roadway, and in particular to an ultra-long mine flat car, which solves the problems that the existing ultra-long flat car cannot be directly turned in the tunnel, and is applicable to the transportation work of different underground narrow roadways. The ultra-long mine flat car comprises a front flat car (11) and a rear flat car (12), wherein the front surface of the rear end of a car body of the front flat car is provided with a connecting male seat (2) with a pin hole, two sides of the rear end of the car body are respectively provided with a fixed device (4) for fixing a dumbbell pin, the front surface of the front end of a car body of the rear flat car is provided with a connecting female seat (1) which is correspondently matched with the connecting male seat and provided with a pin hole, and two sides of the front end of the car body of the rear flat car are respectively provided with a fixed device (4) with a fixed dumbbell pin; the connecting female seat is connected with the connecting male seat through a connecting pin; and the fixed devices on two sides of the front flat car and the rear car are respectively connected with each other through the dumbbell pin (3). The ultra-long mine flat car is reasonable in design and simple in structure, and the transportation requirement of the coal mine equipment train can be met.

Description

The mining flat truck of overlength
Technical field
The utility model relates to the auxiliary conveying equipments of coal mine roadway, is specially the mining flat truck of a kind of overlength.
Background technology
Long flat ore deposit is main force's mine of long flat company, and that produces at present has one, two, four panels.Wherein one, two panel back production modes are the caving coal mining mode, adopt two to advance ventilation type one time, and an air intake lane is crossheading belt lane, and another air intake lane is the equipment train lane for the assistant conveyance lane.The equipment train lane generally is furnished with 21 equipment trains, and all power supplies, water supply, feed flow and control system equipment all are installed on the equipment train.Because fully mechanized coal face electromechanical appliance power supply grade is 3300 VAdopt Bake, Tianjin load center to control; three power supply mobile substation separate unit length are 6m; when using in the past normal length flat truck (length is 3m); the high-head of mobile substation and low pressure side load center are all overhanging outside flat truck; tending to take place height when transportation bows; the load center collision causes device damage; for my ore deposit of protection equipment is transformed into overlength flat truck (length is greater than 6m) to the ordinary flat car that transports the mobile substation; as Fig. 1; shown in 2; bicycle length is 6.3m; because length over ends of body is longer; flat truck wheelbase minimum is more than the 3m; but span length only is 4.8m under the long flat mine; gauge is 600mm, and the bend when turn round in the tunnel all is to require the flat truck wheelbase to control below 2m, otherwise the overlength flat truck will be jumped when turning round; overturn.
The method of Cai Yonging was after the overlength flat truck is transported to the corner in the past, utilized the cat fall that rises accomplish fluently in advance to hang overlength flat truck headstock, cooperate again the place ahead at a slow speed winch slowly little by little turn round.This kind method is time-consumingly to take a lot of work also very dangerously, careless slightly again, and the jack winch of not working good also can overturn, jump the road, and transportation brings great potential safety hazard to mine.
Therefore, be necessary to invent the mining flat truck of a kind of novel overlength.
Summary of the invention
The utility model provides a kind of novel overlength mining flat truck in order to solve the problem that existing overlength flat truck can't turn round voluntarily in existing tunnel.
The utility model is to adopt following technical scheme to realize:
The mining flat truck of a kind of overlength, flat truck and rear plate car before comprising, the front, car body rear end of flat truck is provided with the connection male seat that has pin-and-hole, the anchor fitting that its both sides, car body rear end are respectively equipped with the solid dumbbell pin before described, and the car body front end front of described rear plate car is provided with and the described connection female seat that has pin-and-hole of male seat corresponding matching, the anchor fitting that its car body front end both sides are respectively equipped with the solid dumbbell pin of being connected; Described connection female seat be connected male seat and connect by connecting pin; The both sides anchor fitting of flat truck and rear plate car is connected by dumbbell pin respectively before described.
During work, when the overlength flat truck of the long power supply mobile substation of transportation 6m is transported to the location that need turn round, as long as the connecting pin that will connect male seat and connect between the female seat pulls out, utilize toughness and the activity of dumbbell pin in anchor fitting of dumbbell pin, flat truck and the split of rear plate car before realizing but also keep a kind of soft state (realizing by dumbbell pin) that connects, like this since the rear plate axletree apart from control below 2m, can realize steadily turning round of overlength flat truck, can not overturn, jump the road phenomenon.
Described dumbbell pin is the general a kind of means that are connected in this area with its anchor fitting, does not have technical difficulty to those skilled in the art.
The utility model is reasonable in design, simple in structure, satisfies the transportation request that equipment train is used in the colliery, and the safety that has improved equipment train has solved the problem that the overlength flat truck can't directly directly turn round in the tunnel, be applicable to each narrow opening, down-hole transport.

Among the figure, 1-connects female seat, and 2-connects male seat, 3-dumbbell pin, 4-anchor fitting, flat truck before the 10-flat truck, 11-, 12-rear plate car.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
Shown in Fig. 3,4,5, the mining flat truck of a kind of overlength, flat truck 11 and rear plate car 12 before comprising, the front, car body rear end of described preceding flat truck 11 is provided with the connection male seat 2 that has pin-and-hole, the anchor fitting 4 that its both sides, car body rear end are respectively equipped with the solid dumbbell pin; The car body front end front of described rear plate car 12 is provided with and the described connection female seat 1 that has pin-and-hole of male seat 2 corresponding matching, the anchor fitting 4 that its car body front end both sides are respectively equipped with the solid dumbbell pin of being connected; Described connection female seat 1 be connected male seat 2 and connect by connecting pin; The both sides anchor fitting 4 of flat truck 11 and rear plate car 12 is connected by dumbbell pin 3 respectively before described.
During concrete enforcement, the length ratio of described preceding flat truck 11 and rear plate car 12 is 1:4.
Flat truck 11 has an axletree before described, and described rear plate car 12 has two axletrees.Forward and backward flat truck split keeps the soft state that connects when turning round, and the wheelbase of rear plate car control has simultaneously been satisfied the requirement of turning round in actual tunnel below 2m.
