Description

Clamp device for hoisting steel rail

Technical Field

The utility model relates to a hoist and mount rail clamp device belongs to railway system rail hoist and mount special lifting device equipment technical field.

Background

In the process of hoisting and laying the steel rail, steel wire ropes are usually adopted for binding and hoisting operation during hoisting, but when the steel rail is laid, the steel wire ropes are difficult to take out after the steel rail is in place due to the fact that a beam is in contact with the ground or a ground foundation, and construction operation efficiency is affected. The scissor-type lifting appliance is used, the hook head can be freely opened and closed, but when the steel rail is lifted, the hook head is easily unhooked, the progress of construction operation is influenced, the steel rail is damaged, and certain potential safety hazards can be generated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a hoist and mount rail clamping device, the hoist and mount operation of completion rail that can convenient and fast avoids the rail unhook, reduces and impairs or injures staff's danger by a crashing object, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

The utility model provides a hoist and mount rail clamping device, contain the hanging beam, the activity hook plate, fixed hook plate, the pivot, the hole for hoist, the spacer pin, a spring, spring cardboard and spacing hole, the upper end of hanging beam is equipped with the hole for hoist, the lower extreme of hanging beam is fixed into an organic whole structure with fixed hook plate, the lower extreme of hanging beam passes through the pivot and rotates with the activity hook plate to be connected, activity hook plate and fixed hook plate mutual disposition constitute with rail matched with clamp, be equipped with spacing hole on the activity hook plate, be equipped with the spacer pin with spacing hole matched with on the hanging beam, be equipped with the spring on the spacer pin, the both ends of spring are equipped with the spring cardboard respectively.

The limiting pin is fixed on the hanging beam through spring clamping plates at two ends of the spring.

And the spring clamping plate is provided with a limiting pin sliding groove matched with the limiting pin.

The limiting pin is inserted into the limiting hole of the movable hook plate.

Adopt the utility model discloses, extract the spacer pin from spacing hole, lift up the activity hook plate, put the rail undervolume with fixed hook plate, put down the activity hook plate, the spacer pin is in the spacing downthehole of spring action downwardly inserting the activity hook plate, prevents that the activity hook plate from lifting up, and fixed hook plate folds up the rail because of self gravity with the activity hook plate, then can lift by crane the rail.

The utility model has the advantages that: the hoisting operation of completion rail that can convenient and fast avoids the rail unhook, reduces and bumps or injures staff's danger by a crashing object, can reduce the damage of rail moreover.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to the attached figure 1 ~ 4, the clamp device for hoisting the steel rail comprises a hoisting beam 1, a movable hook plate 2-1, a fixed hook plate 2-2, a shaft pin 3, a hoisting hole 4, a limiting pin 5, a spring 6, a spring clamping plate 7 and a limiting hole 9, wherein the hoisting hole 4 is arranged at the upper end of the hoisting beam 1, the lower end of the hoisting beam 1 and the fixed hook plate 2-2 are fixed into an integral structure, the lower end of the hoisting beam 1 is rotatably connected with the movable hook plate 2-1 through the shaft pin 3, the movable hook plate 2-1 and the fixed hook plate 2-2 are oppositely arranged to form a clamp matched with the steel rail, the limiting hole 9 is arranged on the movable hook plate 2-1, the limiting pin 5 matched with the limiting hole 9 is arranged on the hoisting beam 1, the spring 6 is arranged on the limiting pin 5, and the spring clamping plate 7 is respectively arranged.

The specific embodiment is as follows:

In this embodiment, referring to fig. 1-4, the spring catch plate 7 is provided with a stop pin sliding slot 8 matching with the stop pin 5, the stop pin 5 is fixed on the stop pin sliding slot 8 of the hanging beam 1 through the spring catch plates 7 at both ends of the spring 6, and the lower end of the stop pin 5 can be inserted into the stop hole 9 of the movable hook plate 2-1.

The steel rail hoisting process comprises the following steps:

referring to the attached drawings 5 and 6, the limiting pin 5 is pulled out of the limiting hole 9 of the movable hook plate 2-1, the movable hook plate 2-1 is lifted, the fixed hook plate 2-2 is placed below the steel rail, the movable hook plate 2-1 is put down, the limiting pin 5 is downwards inserted into the limiting hole 9 of the movable hook plate 2-1 under the action of the spring 6 to prevent the movable hook plate 2-1 from being lifted, the fixed hook plate 2-2 and the movable hook plate 2-1 are folded to wrap the steel rail due to self gravity, and then the steel rail can be lifted. When the steel rail is lifted, the steel rail generates friction force and shearing force with the fixed hook plate 2-2 and the movable hook plate 2-1 due to gravity, and the limiting pin 5 is inserted into the limiting hole 9 of the movable hook plate 2-1, so that the movable hook plate 2-1 is prevented from opening, and the phenomenon of unhooking of the steel rail is avoided.
