Description
Technical field
The utility model relates to a kind of car retarder, particularly relates to a kind of easy-to-mount car retarder brake clamp group.
Background technology
Brake clamp group in traditional car retarder is to utilize the boss of rail bearing itself to be suspended on plane on the flange of rail of rail, and the rail bearing is an integral structure, must wear inward from an end of rail during installation.12～18 brake clamp groups will be installed on the rail of a common 25m.In the use, change wherein some rail bearings if desired, just must all withdraw from rail to the rail bearing of its front (or back), single rail bearing 1 is non-dismountable, and the difficulty of replacing is very big.
Change the rail bearing in the brake clamp group for convenience, a kind of car retarder with open rail bearing has appearred, the rail bearing of described car retarder no longer includes boss, but be provided with boss at the head of medial and lateral brake clamp, and be supported on the last plane of the rail flange of rail respectively, when needs are changed the rail bearing, only the main shaft that open rail bearing need be connected with inside and outside brake clamp is removed, described rail bearing is promptly separated with brake clamp, conveniently independently dismantles from rail.
But above-mentioned car retarder has increased the difficulty of independent replacing brake clamp.Because what be responsible for supported and suspended whole brake clamp group is the brake clamp that has boss, when changing brake clamp, the rail bearing can't independent suspension on rail, must install with the brake clamp after changing, this has increased the work difficulty of independent replacing brake clamp to a certain extent.
The utility model content
The purpose of this utility model is to provide a kind of new easy-to-mount car retarder brake clamp group, by between brake clamp and rail bearing back-up block being set, can make things convenient for rail socket mounting and replacing, also can make things convenient for the installation and the replacing of brake clamp simultaneously.
The technical scheme that the utility model adopted is: a kind of easy-to-mount car retarder brake clamp group, and this brake clamp group has: a pair of brake clamp lays respectively at the rail both sides, and shape and size are identical; A pair of braking rail lays respectively at the rail both sides and is fixed on the brake clamp of homonymy; One rail bearing is asymmetric, open, detachable bearing, and rail bearing both sides have spindle hole, are connected with brake clamp by main shaft; It is characterized in that:
Between described brake clamp and the rail bearing back-up block is set, back-up block is positioned at rail bearing inboard, back-up block is connected with the rail bearing by axle sleeve, and brake clamp, rail bearing, back-up block and axle sleeve connect into assembly by main shaft, and assembly is suspended on rail by back-up block;
Described brake clamp head arranged outside one confined planes is provided with another confined planes on the contiguous block of rail bearing.
Further preferred scheme is: described rail bearing comprises stiffening plate, and two back-up blocks are set between each brake clamp and the rail bearing, and an end is suspended on the last plane of the rail flange of rail, and the stiffening plate of the other end and rail bearing is fitted.
The external cylindrical surface of axle sleeve described in the technique scheme is a step surface, and axle sleeve is installed on the rail bearing from inside to outside.
Facade and bottom surface transition that described rail bearing is positioned at the side plate of rail inboard are the inclined-plane, and the facade and the bottom surface transition that are positioned at the side plate in the rail outside are arc surface.
The beneficial effects of the utility model are:
(1) rail both sides brake clamp shape and size are identical, avoid must laying in two kinds of different brake clamps in time changing, and bring great convenience for equipment working service unit.
When (2) changing brake clamp, the rail bearing still can be suspended on the rail by axle sleeve and back-up block.When needs are changed the rail bearing, the brake clamp of dismantling, the back-up block of dismantling again, the rail bearing just can directly be unloaded down from rail, and will other rail bearing not withdraw from one by one from rail.
(3) on the contiguous block of brake clamp and rail bearing a confined planes is set respectively, fits when brake clamp rotates to latter two confined planes of certain position, the restriction brake clamp excessively overturns, the safety when having guaranteed car retarder work.
(4) external cylindrical surface of axle sleeve is a step surface, and axle sleeve is installed on the rail bearing from inside to outside, has both connected back-up block and rail bearing, has prevented the end float misalignment of self again.
(5) to be positioned at the facade and the bottom surface transition of the side plate of rail inboard be the inclined-plane to the rail bearing, and the facade and the bottom surface transition that are positioned at the side plate in the rail outside are arc surface, avoids non-symmetrical rail bearing to adorn reversing sense.

The specific embodiment
Below in conjunction with accompanying drawing the concrete structure that this is suitable for novel proposition is further described:
As shown in Figure 1, two brake clamps 2 are identical.Inequality for the end face of the braking rail 3 that guarantees both sides from the centre distance of rail 5, avoid the brake clamp of wheel 4 backing inboards to increase wearing and tearing, adopted asymmetric rail bearing, a ≠ b among the figure.For avoiding rail bearing dress anti-, making an inclined-plane near on the side plate 11 of orbit centre, opposite side is an arc surface.
Fig. 2 is the car retarder release position scheme drawing with this brake clamp group.
From Fig. 2 to Fig. 1, the confined planes 9 of brake clamp 2 is progressively fitted with the confined planes 10 of rail bearing 1, and the excessive upset of brake clamp has been limited, the safety when having guaranteed car retarder work.
Because when car retarder was in the release position, the brake clamp group must be suspended on the rail 5, as shown in Figure 2.For realizing this function, both sides at each brake clamp 2 increase by 2 back-up blocks 7, and back-up block 7 is installed in the inboard of detachable rail bearing 1, is connected with rail bearing 1 by axle sleeve 8, one end is suspended on the rail 5, and the stiffening plate 12 of the other end and rail bearing 1 is fitted.Brake clamp 2, axle sleeve 8, back-up block 7, rail bearing 1 etc. connect into an assembly by main shaft 6, as shown in Figure 3.When changing brake clamp 2, rail bearing 1 still can be suspended on the rail 5 by axle sleeve 8 and back-up block 7.When needs are changed certain rail bearing 1, the back-up block 7 of dismantling again, rail bearing 1 just can directly be unloaded down from rail 5, and will other rail bearing 1 not withdraw from one by one from rail 5.
The structural representation at the brake clamp group main shaft place that Fig. 3 carries for the utility model.The external cylindrical surface of axle sleeve 8 is a step surface, and axle sleeve 8 is installed on rail bearing 1 from inside to outside.Adopt step surface, both connected rail bearing 1 and back-up block 7, prevented the end float misalignment of self again.
As shown in Figure 4, rail bearing 1 is asymmetric, open, detachable rail bearing, need not to wear rail 5 during dismounting.
Fig. 5 is the structural representation of back-up block 7.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the covering scope of the utility model patent.
