Abstract

The utility model relates to a mousing-hook self-locking device which belongs to the technical field of a safety protection device for mine track transport. The mousing-hook self-locking device comprises a first fixing plate, a driven hook, a drive hook, a second fixing plate, a spring and a connecting rod, wherein the drive hook and the driven hook are articulated with the fixing plates respectively; the connecting rod is used for connecting the drive hook with the driven hook so that the drive hook and the driven hook can perform relative movement; the spring is connected with the connecting rod and the drive hook; due to a restoring force of the spring, the drive hook acts on the driven hook by the connecting rod when no external force is applied on the drive hook, so that the device can automatically return; and when the mousing-hook self-locking device is used, only a manipulation connecting rod at one end of the drive hook needs to be pulled. The mousing-hook self-locking device has a main purpose that additional mechanical protection is adopted for a lifting cab, and the mousing-hook self-locking device can prevent cab lifting misoperation in the transport process of a monorail crane.

Description

The lock hook self-locking device

Technical field

The utility model relates to the safety guard of mine rail transportation, especially a kind of lock hook self-locking device for preventing the maloperation of monorail crane transportation cab lift.

Background technology

The monorail crane operator's compartment utilizes hydraulic actuating cylinder pushing tow carriage to drive the roller that is fixed on the carriage and rolls to realize lifting along guide rail, and the monorail crane operator's compartment does not have fender guard after rising, and may have an accident because maloperation descends monorail crane operator's compartment when operation.

The utility model content

The utility model is for the deficiencies in the prior art, and a kind of lock hook self-locking device that prevents cab lift maloperation in the monorail crane transportation is provided.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the lock hook self-locking device, comprise: the first adapter plate, driven hook, active hook, the second adapter plate, spring, connecting rod, the top of described active hook and driven hook is hook, active hook and driven hook are staggered relatively, it is characterized in that: the bottom-hinged of described driven hook is on the first adapter plate, and the middle part of active hook is hinged on the second adapter plate; One end of described connecting rod and the middle part of driven hook are hinged, and the other end of connecting rod and the middle and lower part of active hook are hinged, and an end of spring and the middle part of connecting rod are hinged, and the other end of spring is connected with the middle and upper part of active hook; Described active hook and driven hook can hang on the boss that matches with active hook and driven hook.

The handle of the bottom of described active hook for ease of holding.

Described the first adapter plate upper end is fixed on operator's compartment top board lower surface one side, and the second adapter plate upper end is fixed on operator's compartment top board lower surface opposite side.

The hook portion that described active hook and driven hook pass operator's compartment top board mating holes is positioned on the operator's compartment top board, on the boss above hook portion can hang on the fixed mount.

The beneficial effect that the utility model compared with prior art has is: adopts the lock hook self-locking device, improved the safety factor of operator's compartment, it can oneself not fallen in the situation of maloperation, thus many one mechanical protections; Utilize the spring reset principle, need not manually to reset to handling cross bar, easy to operate; This apparatus structure is simple, cost is low, be convenient to maintenance.

Description of drawings

Be described in further detail below in conjunction with the specific embodiment of accompanying drawing to the utility model lock hook:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is use constitution diagram of the present utility model;

Among the figure: 1 is the first adapter plate, and 2 is driven hook, and 3 is active hook, and 4 is the second adapter plate, and 5 is spring, and 6 is connecting rod.

The specific embodiment

Lock hook self-locking device as shown in Figure 1 comprises: the first adapter plate 1, driven hook 2, active hook 3, the second adapter plate 4, spring 5 and connecting rod 6, and the top of described active hook 3 and driven hook 2 is hook, and active hook 3 and driven hook 2 are staggered relatively; The bottom-hinged of described driven hook 2 is on the first adapter plate 1, and the middle part of active hook 3 is hinged on the second adapter plate 4; One end of described connecting rod 6 and the middle part of driven hook 2 are hinged, and the middle and lower part of the other end of connecting rod 6 and active hook 3 is hinged, and an end of spring 5 and the middle part of connecting rod 6 are hinged, and the other end of spring 5 is connected with the middle and upper part of active hook 3; Described active hook 3 and driven hook 2 can hang on the boss that matches with active hook 3 and driven hook 2.

The handle of the bottom of described active hook 3 for ease of holding.

Described the first adapter plate 1 upper end is fixed on operator's compartment top board lower surface one side, and the second adapter plate 4 upper ends are fixed on operator's compartment top board lower surface opposite side.

Described active hook 3 is positioned on the operator's compartment top board with the hook portion that driven hook 2 passes operator's compartment top board mating holes, on the boss above hook portion can hang on the fixed mount.

As shown in Figure 2: when the boss on the walker of operator's compartment top moved downward, boss acted on the gib head inclined-plane of driven hook 2 and active hook 3 simultaneously, makes driven hook 2 and active hook 3 to outward turning, spring 5 elongations; Boss on the walker of operator's compartment top is during down to end position, and the gib head application force of boss and driven hook 2 and active hook 3 disappears, and spring 5 shrinks, and driven hook 2 and active hook 3 are resetted, the realization self-locking.

Manipulation cross bar when downward pulling active hook 3 belows, active hook 3 is take its second adapter plate 4 hinge-points as axial inner rotary, active hook 3 drives driven hook 2 outside turns by connecting rod 6, spring 5 applied elongation, then can cancel locking, the walker a bit of distance that rises in operator's compartment top is unclamped hand, because be subjected to the restoring force of spring 5, the lock hook self-locking device automatically resets.

The utility model lock hook self-locking device, reliable and stable, compact conformation, easy to operate.

The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
