Abstract
The utility model relates to a tank car sealing lock which is characterized in that a through hole (1) and a communicated inclined hole (2) are formed in a lock body (4); the two holes form an included angle of 14-18 degrees; a steel ball (8) and a spring (9) are arranged in the inclined hole (2); a connection column (5) is in scarf joint with the end part of the lock body; the connection column is connected with a steel cable (6); the other end of the steel cable is connected with a plug head (7); the plug head (7) is inserted in the through hole (1) to push the steel ball to the inclined hole; and when the steel cable bears stress in the opposite direction, the steel ball applies force on the steel cable along the inclined hole under the action of the spring so as to form the stepless self-locking of the steel cable. The utility model has the advantages that the technical scheme of the stepless pulling and locking structure is adopted so that the tank car to be locked is tightly locked without looseness; in the locking state, the entire static tension fracture load reaches 1.8 times of standard requirements; and the stepless sealing lock of the tank car is convenient and reliable, without false locking and secondary locking.
Description
Technical field:
The utility model relates to a kind of tank car sealing lock that is exclusively used in the transportation by railroad.
Background technology:
Present widely used sealing lock is mainly used in container or box car is executed envelope, but for tank car, and it is bigger to execute the envelope difficulty because that tank car shakes in transit is very big, sealing lock easily with phenomenon such as tank body generation friction, often cause some unnecessary damages.In addition, existing sealing lock structure more complicated can not stepless locking, and the cost of sealing lock is also higher.
The utility model content:
The purpose of this utility model is exactly a kind of tank car sealing lock that proposes for the defective that solves the prior art existence.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of tank car sealing lock, it comprises lock body, it is characterized in that: a through hole and an inclined hole are set in the lock body, two holes communicate and are 14-18 degree angle, be provided with steel ball and spring in the inclined hole, joint pin of lock body end interlocking, connect steel cable in the joint pin, the other end of wire rope connects a bolt head, when the bolt head inserts in the through hole steel ball is squeezed back in the inclined hole, reverse when stressed when wire rope, steel ball is exerted pressure to wire rope at the effect lower edge of spring inclined hole and is formed the wire rope self-locking, can reach the purpose of stepless tension locking.
The utlity model has following advantage:, make by the lock tank car and seal the tight lock of realization non-loosening owing to adopt above-mentioned stepless tension locking structure technology scheme.Whole static fail in tension load reaches 1.8 times of standard-required under locking states.The stepless tension tank car of this structure sealing lock is convenient and reliable, does not have false locking and secondary locking.
Description of drawings:
Fig. 1 is a cut-open view of the present utility model;
Embodiment:
As shown in Figure 1, tank car sealing lock described in the utility model, it comprises lock body 4, a through hole 1 and an inclined hole 2 are set in the lock body 4, two holes communicate and are 15-16 degree angle, are provided with steel ball 8 and spring 9 in the inclined hole 2, and the bottom is blocked inclined hole 2 and spring 9 with end socket 2.Joint pin 5 of lock body upper end interlocking, connect steel cable 6 in the joint pin, the other end of wire rope connects a bolt head 7, when bolt head 7 inserts in the through hole 1 steel ball is squeezed back in the inclined hole, when wire rope reverse when stressed, steel ball is exerted pressure to wire rope at the effect lower edge of spring inclined hole and is formed the wire rope self-locking, can reach the purpose of stepless tension locking.
