Abstract
The utility model relates to a wheel drop mechanism for a passenger train, particularly a device for replacing wheel pairs of a passenger train. The existing passenger trains adopt the wheel drop method that a carriage is jacked by an air cylinder, and then sizing blocks are used for underlying the carriage; the fall of the air cylinder drives the wheel pairs to drop, and people can push out old wheels and push in new wheels for replacement; or the wheel drop method can be that the carriage can be hoisted by a crane, and wheels are replaced manually; both methods are of high work intensity and low efficiency. The utility model is characterized in that four hydraulic hoist cylinders 3 are fixed between a wheel drop platform 1 and a walking platform 2, wherein, two steel rails 6 with same length are fixed on the wheel drop platform 1, and four hydraulic safety cylindrical pin cylinders 7 are fixed under the wheel drop platform 1; four wheels 9 are fixed under the walking platform 2. The utility model is suitable for dropping wheels of passenger trains of various models and has the advantages of convenient operation, strong hoisting capacity due to the adoption of hydraulic transmission, compact structure, small floor area, exact positioning and high safety.
Description
Technical field: the utility model relates to passenger train and changes the right a kind of device of wheel, particularly passenger train wheel drop mechanism.
Background technology: it is to changing on the Luntai position with the compartment traction that existing passenger train changes the wheel method, cylinder on the platform position is with compartment jack-up, then with parallels with on the compartment pad, cylinder falls will take turns falling, choose again and take turns release old, new wheel pushes takes turns replacing, or with crane is sling in the compartment, and then manually changes wheel.These two kinds of methods, labor strength is big, and production efficiency is low, can not adapt to the needs of railway transportation development.
The utility model content: the utility model is a kind of passenger train wheel drop mechanism of development, and it is strong that it should have a jacking capacity, wide accommodation, and work safety is reliable and stable, and is simple to operate, is easy to safeguard the characteristics that production efficiency is high.The utility model includes wheel platform 1, travelling platform 2; Fall to taking turns and be fixed with four hydraulic lifting oil cylinders 3 between platform 1 and the travelling platform 2, fall to taking turns above platform 1 is arranged on, below travelling platform 2 is arranged on, the inferior part of the cylinder block of four hydraulic lifting oil cylinders 3 is separately fixed on four jiaos of travelling platform 2, piston rods 4 in four hydraulic lifting oil cylinders 3 are separately fixed at four jiaos of wheel platform 1, fall to taking turns the top of platform 1 and between two long limit 1-1, two parallel isometric rail 6 are arranged with two long limit 1-1 vertical fixing, the distance of two one steel rails 6 equates with the railway standard gauge, the inboard that falls to taking turns following four piston rods 4 of 1-1 both sides, platform 1 long limit is fixed with four hydraulic safe pin oil cylinders 7 respectively, stretch out the safe pin of returning 8 and be located in the safe pin oil cylinder 7 along falling to taking turns the long limit of platform 1 1-1 vertical direction, the bottom of travelling platform 2 is fixed with four wheels 9, the top of travelling platform 2 is fixed with movable motor 10, Hydraulic Pump 11, pump motor 12, wheel 9 is in transmission connection by chain 16 with movable motor 10, the bottom of operator's station 13 is fixed on the travelling platform 2, hand valve 14, button case 15 is fixed on the operator's station 13.The utility model falls to taking turns applicable to the passenger vehicle of various models, and is easy to operate, reasonable in design, adopts hydrostatic drive, and jacking capacity is strong, wide accommodation, and the compact conformation floor area is little, and accurate positioning is safe and reliable, the production efficiency height.
Description of drawings: Fig. 1 is an integral structure scheme drawing of the present utility model, and Fig. 2 is the utility model and track bond and the timer-operated structural representation of safety post lock.
The specific embodiment: present embodiment includes wheel platform 1, travelling platform 2, fall to taking turns and be fixed with four hydraulic lifting oil cylinders 3 between platform 1 and the travelling platform 2, fall to taking turns above platform 1 is arranged on, below travelling platform 2 is arranged on, the inferior part of the cylinder block of four hydraulic lifting oil cylinders 3 is separately fixed on four jiaos of travelling platform 2, piston rods 4 in four hydraulic lifting oil cylinders 3 are separately fixed at four jiaos of wheel platform 1, fall to taking turns the top of platform 1 and between two long limit 1-1, two parallel isometric rail 6 are arranged with two long limit 1-1 vertical fixing, the distance of two one steel rails 6 equates with the railway standard gauge, the inboard that falls to taking turns following four piston rods 4 of 1-1 both sides, platform 1 long limit is fixed with four hydraulic safe pin oil cylinders 7 respectively, stretch out the safe pin of returning 8 and be located in the safe pin oil cylinder 7 along falling to taking turns the long limit of platform 1 1-1 vertical direction, the bottom of travelling platform 2 is fixed with four wheels 9, the top of travelling platform 2 is fixed with movable motor 10, Hydraulic Pump 11, pump motor 12, wheel 9 is in transmission connection by chain 16 with movable motor 10, the bottom of operator's station 13 is fixed on the travelling platform 2, hand valve 14, button case 15 is fixed on the operator's station 13.
Working process: the utility model generally is two to be used simultaneously, the utility model is installed in the walking passage that is positioned at underground, the walking passage is positioned at the two ends of wheel line, distance is the distance between a joint compartment two bogie trucks between the two walking passages, establish two rail in that the walking channel bottom is auxilliary, the trend of walking passage is with to fall to taking turns line vertical.The compartment traction that needs replacing wheel is right is to the wheel drop mechanism platform position that falls to taking turns on the line, and the wheel that makes replacing is to aiming at two rail 6 on the wheel drop mechanism, rail 6 and the butt and butt of the open circuited circuit rail of quilt walking passage.At first hydraulic safe pin oil cylinder 7 work, safe pin 8 is return from the column keyway in the walking passage, can control the rising of hoist cylinder and landing makes hoist cylinder 3 work by manual and electronic dual mode, allow wheel platform 1 rise, be raised to certain altitude, steady with parallels the compartment pad, fall wheel platform 1 again, the wheel that need fall is to fall thereupon.The wheel that falls will be taken turns sending the wheel line by the moving on walking passage rail of the wheel 9 under the travelling platform 2, send repair line to, transport new wheel back from repair line then, be installed on the compartment that is overhauled, install and rise the compartment and remove parallels, fall to taking turns platform 1 original position that falls back.Must earlier safe pin 8 be stretched out the column keyway that inserts on the walking passage, form safe crane span structure, just the compartment can be pulled out, can guarantee like this vehicle by the time safety.
