Abstract
The utility model discloses a two-ring horizontal rotary hard connection device for connection of driving vehicles at a gate way, and relates to the technical field of machinery equipment for conveying personnel in an underground roadway. The two-ring horizontal rotary hard connection device comprises a hollow connection sleeve with an end with a large internal diameter and the other end with a small internal diameter, a first connecting shaft which is inserted into the end with a the large internal diameter of the connection sleeve, fixed on the connection sleeve, and provided with a hinge cut formed in one end, and a second connecting shaft which is inserted into the end with the small internal diameter of the connection sleeve and provided with a hinge cut formed in one end, wherein a check ring for preventing the second connecting shaft from being pulled out of the connecting sleeve is arranged at one end, inserted into the connection sleeve, of the second connecting shaft. The two-ring horizontal rotary hard connection device has the advantages as follows: the vehicles can be connected into a whole, a pedestrian vehicle and an electric vehicle can be started, accelerate, run at an even speed, decelerate and stop simultaneously, as a result, the problems that when the vehicles connected through a standard three-ring chain are started and stopped, the impact of the vehicles is large, the vehicles are unstable, personnel in the vehicles are uncomfortable, and the driving vehicles can deviate from the track and are turned over are completely solved.
Description
Technical field
The utility model relates to the mechanical equipment technical field of the underworkings conveying peoples such as a kind of colliery, and specifically a kind of two rings that connect for tunnel man-bus horizontally rotate hard connecting device.
Background technology
Gallery man-powered vehicle is used standard ring chain to be connected with Φ 40mm latch always at present.Three lugless joining shackles of ring chain are nested, and can shrink overlapping and pull open elongation, and this structural disadvantages is: when opening, stopping, car impact is large, not steady, and during top car warehouse-in, intermediate link may erect and can not pull open, and exists the hidden danger that slides down, overturns.
Summary of the invention
For existing practical problems in above-mentioned, the utility model provides a kind of two rings to horizontally rotate hard connecting device.
The utility model is realized with following technical scheme: a kind of two rings horizontally rotate hard connecting device, comprise the hollow coupling bush that large one end, internal diameter one end is little; Insert one end that coupling bush internal diameter is large and be fixed on coupling bush, one end has the first adapter shaft of pin hole; The second adapter shaft that one end that insertion coupling bush internal diameter is little and one end have pin hole; One end that described the second adapter shaft inserts coupling bush is also fixed with and stops that the second adapter shaft pulls out the back-up ring of coupling bush.
It is further: described first adapter shaft one end and coupling bush are welded to connect, and the other end has oblate pin hole.
The second described adapter shaft can rotate in coupling bush, its one end and back-up ring are welded to connect, and the other end has oblate pin hole.
Between the first described adapter shaft and the second adapter shaft, leave space.
This two ring horizontally rotates hard connecting device alternate standard ring chain and uses, adapted Φ 40mm latch, and between two adapter shafts, 360 ° of horizontal rotaries of energy, have 2-5mm free gap, to meet track cross level error needs.
The beneficial effects of the utility model are: adopt this hard connection can make permutation car be linked to be an integral body, can start, acceleration, average rate move, slow down, stop between man-powered vehicle and electric locomotive simultaneously, in starting and stopped process, operate steadily.Can eliminate uncomfortable sensation that the impact of man-powered vehicle in starting and docking process causes occupant.When top car moves, hard connection is subject to jacking force, and people's car exists larger gap not contact all the time between meeting and discussing, so can there is not the danger of overturning, move safer.
Accompanying drawing explanation
Fig. 1 is the structural representation that two rings horizontally rotate hard connecting device
In figure: 1, coupling bush; 2, the first adapter shaft; 3, the second adapter shaft; 4, back-up ring; 5, pin hole.
The specific embodiment
Be below a specific embodiment of the present utility model, by reference to the accompanying drawings the utility model be described further.
As shown in Figure 1, a kind of two rings horizontally rotate hard connecting device, comprise the hollow coupling bush 1 that large one end, internal diameter one end is little; Insert one end that coupling bush 1 internal diameter is large and be welded on coupling bush 1, one end has the first adapter shaft 2 of pin hole 5; Insert the second adapter shaft 3 that one end that coupling bush 1 internal diameter is little and one end have pin hole 5, the second described adapter shaft 3 can the interior rotation of coupling bush 1 and and the second adapter shaft 3 between leave space; One end that the second adapter shaft 3 inserts coupling bushs 1 is also welded with and stops that the second adapter shaft 3 pulls out the back-up ring 4 of coupling bush 1.
It is 27SiMn alloy structureal steel that a kind of two rings horizontally rotate hard connecting device material used.Described coupling bush 1 is turning workpiece: external diameter Φ 95 * 100mm, left end small-bore Φ 45.5 * 30mm, right-hand member inner chamber Φ 65.5 * 70mm.Back-up ring 4 scantling of structure are Φ 45.5 * Φ 65 * 30mm.The second adapter shaft 3 is Forging Parts, latch nose end size Φ 45 * Φ 100mm, thickness 40mm.The first adapter shaft 2 is Forging Parts, latch nose end Φ 45 * Φ 100mm, thickness 40mm, middle segment length 60mm, wide 65mm, thick 40mm, in addition one end Φ 65 * 40mm.
Assembling process: first the second adapter shaft 3 packed into by the Φ 45mm axle head of coupling bush 1 and shift the end onto, then back-up ring 4 covers are installed to the Φ 45mm axle head of the second adapter shaft 3, concordant with axle head, and back-up ring 4 axle heads are connected with the second adapter shaft 3 successive weldings, leg height is 8mm, again the second adapter shaft 3 is return back to the Φ 45mm axle head of coupling bush 1, by Φ 65 * 40mm axle head dress coupling bush 1 Φ 65.5 * 70mm inner chamber of the first adapter shaft 2, make the first adapter shaft 2 and 3 of the second adapter shafts have 2-5mm free gap, the second adapter shaft 3 in coupling bush 1 rotation freely, again the first adapter shaft 2 is connected with coupling bush 1 successive welding, leg height is 8mm.
