Description
Technical field
The common decelerating of high load capacity described in the utility model belongs to a kind of decelerating speed control device in marshaling yard field speed control device, particularly marshaling yard field hump speed control system.
Background technology
Decelerating is the widely used a kind of automation speed control device in lorry marshalling station field, and it is fixedly mounted on rail, the train speed to be grouped that Based Intelligent Control slides, thus realizes vehicle with the object of safety speed even extension.
Along with a large amount of place in operations of heavy-duty vehicle, existing decelerating and the comformability of speed governing system to heavy-duty vehicle thereof become worse and worse, need the more superior decelerating of performance to meet the Operational requirements of heavy-duty vehicle, ensure transport production safety and carry out smoothly.Although existing traditional decelerating kind is a lot, except function, range of use and performance respectively possess some good points, this decelerating of braking work technical performance index of paramount importance all compares shortcoming, urgently improves.The mounting hole of existing medial and lateral decelerating lacks commonality when various rail type is installed simultaneously.In addition between decelerating sliding oil cylinder and the inwall of housing, and friction between piston rod head and sliding oil cylinder inwall is inevitable when decelerating uses, easily cause the wearing and tearing of piston rod head and movable cylinder body inwall, thus increase the maintenance work amount of decelerating, reduce the service life of decelerating.
Utility model content
The purpose of this utility model is: on existing decelerating product basis, carry out key structure redesign and technological improvement, a kind of there are the properties of product being better than existing product not changing to develop under equipment existing safe handling condition, there is longer service life, there is the decelerating of easier maintenance and repair technology characteristic; Thus improve the braking work of decelerating, increase the global reliability of equipment, to meet the Operational requirements of novel load-carrying lorry, ensure transport production safety and carry out smoothly.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
The common decelerating of high load capacity described in the utility model, comprises sliding oil cylinder, piston rod and speed-reduction top housing, and described sliding oil cylinder adopts heavy caliber structure, and described speed-reduction top housing is provided with mounting hole, also comprises a zerk and an oil extraction mouth.
Further improvement of the utility model is, described speed-reduction top housing inwall respectively has a guide ring up and down.
Further improvement of the utility model is, the head cylindrical of described piston rod and described sliding oil cylinder inwall sliding friction pair are set up twice and supported guide ring, and its material adopts cast-iron alloy.
Further improvement of the utility model is, described piston rod comprises a differential flat valve and a blind hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 2, the common decelerating of the high load capacity that the utility model provides comprises housing assembly and sliding oil cylinder assembly two large divisions, sliding oil cylinder assembly is inserted in the housing 9 of housing assembly, lock to stop flushing device 16, sliding oil cylinder assembly is primarily of compositions such as sliding oil cylinder 6, piston rods 11, sliding oil cylinder 6 is filled with gas mixture as working medium in chamber, and housing 9 assembly thru-bolt 8 (containing nut and spring washer) is arranged on inner side or the outside of stock rail.
The utility model sliding oil cylinder intracavity diameter increases to 65mm by 52mm, thus can reduce decelerating acting idle travel.By increasing decelerating sliding oil cylinder internal diameter, the braking work of this decelerating adds the braking work of about 15% than existing decelerating of the same type.
The sliding friction pair of the utility model piston rod 11 head cylindrical and sliding oil cylinder 6 inwall all have employed novel supporting guide frame and designs, namely on piston rod 11 head cylindrical, twice carrier ring 12 is set up, material adopts cast-iron alloy, resistance to abrasion, dynamic airtightness are good, can service life of prolonged deceleration top piston rod, during maintenance, only need to change carrier ring.
Housing 9 inwall design each guide ring 10 up and down, guide ring 10 adopts copper-based alloy material, resistance to abrasion, guidance quality, good airproof performance, the grease injecting housing oil resevoir can be pinned.This structure design also avoid the mode of original decelerating sliding oil cylinder and housing direct friction, thus plays available protecting to housing.During maintenance, only need to change guide ring, thus can service life of prolonged deceleration top shell body, make the 6 years life cycles specified that are above standard its service life, reach more than 10 years.
Piston rod adopts the structure design of differential flat valve+blind hole, in Fig. 2, differential flat valve 13 is a kind of pressure valve structures that in existing pressure valve structure, Stability and adaptability is higher, this structure not only ensures that decelerating braking work is full, meet decelerating speed governing system Operational requirements, and the external environment condition of this structure to decelerating work is adaptable.The blind hole structure design of piston rod 11, is not only easy to processing, is easy to debugging assembling, saves production and processing cost, and can ensure the consistency of performance of decelerating batch manufacturing.The hydraulic fluid leak problem that blind hole structure is also effectively avoided.
The beneficial effects of the utility model are:
Adopt sliding oil cylinder heavy caliber structure design, add the braking work of about 15% than existing decelerating of the same type.Improve the commonality being adapted to inner side decelerating and outer-side retarder mounting hole.Decelerating oiling adopts two oil nozzle structure design, can save the oiling maintenance time, reduce labor intensity.Be provided with copper-based alloy material guide ring in inner walls, improve sliding oil cylinder and housing guidance quality, resistance to abrasion and leak tightness, thus can service life of prolonged deceleration top shell body.Piston rod head sets up the twice cylinder iron carrier ring that makes of alloy, its resistance to abrasion and dynamic airtightness good, can service life of prolonged deceleration top piston rod.
Piston rod adopts differential flat valve+blind hole structure, is a kind of pressure valve structure that in existing pressure valve structure, Stability and adaptability is higher, thus ensures that decelerating braking work is full, meets the Operational requirements of decelerating speed governing system.
