Description

Skid plate formula hydraulic support device of boarding

Technical field

Skid plate formula hydraulic support device of boarding of the present invention, belongs to fortune unwheeling technical field.

Background technology

Support needs to realize by fortune unwheeling during transition is transported, and how support is steadily positioned in fortune unwheeling, it it is a common problem, in prior art, the unwheeling of hoisting type fortune there is problems of front end hook difficulty, i.e. when support is got on the bus, need to be lifted by crane by support by chain, often there is unhook phenomenon in such mode, and need when hook to be manually entered inside fortune unwheeling and could will be connected by chain between fortune unwheeling and support, thus there is the biggest potential safety hazard, additionally, when support lifts by crane, flexibility due to chain, during lifting, support oscillatory is the biggest, often rub with fortune unwheeling and collide, cause the damage of equipment.

Although prior art using the added mode of shovel-type overcome the unstability of the added mode of hoisting type, but it being long to bring the added stroke of traction, the problem that frictional force is big.

Summary of the invention

Instant invention overcomes the deficiency that prior art exists, provide skid plate formula hydraulic support device of boarding, steel wire rope is used to replace original round-link chain that support is drawn, steel wire rope is easier to fix with support and be difficult to break off relations, distracted position uses bracket base rear, pulling force is produced in the horizontal direction so that support enters in fortune unwheeling while angle of inclination becomes level angle while lifting support rear.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is: skid plate formula hydraulic support device of boarding, including U-shaped frame and stent bearing plank, described stent bearing plank is between two sidewalls of U-shaped frame, support to be got on the bus is set on described stent bearing plank, the upper surface of two sidewalls of described U-shaped frame is respectively arranged with drawing oil cylinder, described drawing oil cylinder is vertically installed in the opening of U-shaped frame sidewall, the movable end of described drawing oil cylinder is arranged upward, it is respectively arranged with pulley on the movable end of two described drawing oil cylinder, the steel wire rope for towing bracket it is wound with respectively on two described pulleys, the upper surface of the sidewall of U-shaped frame is fixed in one end of described steel wire rope, the other end of described steel wire rope is arranged on support.

Being provided with hole for hoist on described support, described hole for hoist is two, is symmetricly set in the base rear end of support.

The both sides of the upper surface of described stent bearing plank are respectively arranged with roller, and the quantity of described roller is multiple, symmetrical and be distributed in the both sides of stent bearing plank upper surface uniformly, the width being smaller than support between roller described in symmetrical both sides.

The opening part of described U-shaped frame is provided with for the added hang plate of support.

The present invention compared with prior art has the advantages that

1, this device uses steel wire rope to replace the hook traction of original round-link chain, it is difficult to break off relations, support is first drawn to hang plate during stretching out by drawing oil cylinder at the uniform velocity smoothly from bottom surface, again by the rear portion stretching hoisting bracket of drawing oil cylinder, support is made to be transformed to level angle from angle of inclination, inclination pulling force due to steel wire rope, its component becomes vertically and horizontally both direction, therefore, support rear portion is moved during promoting inside U-shaped frame simultaneously, when support level, support just completely into U-shaped frame inside, process safety of getting on the bus is steady, steel wire only need to be connected with the hole for hoist on support by operator at stent outer, without entering the inside of U-shaped frame, stop potential safety hazard during hook.

2, this device uses roller to replace the added mode of shovel-type, and after support becomes level angle, roller replaces the face of original shovel board to contact with the linear contact lay of support, greatly reduces the frictional force of support and fortune unwheeling so that traction becomes to be more prone to.

3, this apparatus structure is simple, easy to operate, has stopped the phenomenon that chain breaks off relations, greatly reducing manual operation and energy resource consumption.

Fig. 2 is the top view of the present invention.

Figure 1 is U-shaped frame, 2 be stent bearing plank, 3 be support, 4 be drawing oil cylinder, 5 be pulley, 6 be steel wire rope, 7 be hole for hoist, 8 be roller, 9 for hang plate.

Detailed description of the invention

As depicted in figs. 1 and 2, skid plate formula hydraulic support device of boarding of the present invention, including U-shaped frame 1 and stent bearing plank 2, described stent bearing plank 2 is between two sidewalls of U-shaped frame 1, support 3 to be got on the bus is set on described stent bearing plank 2, the upper surface of two sidewalls of described U-shaped frame 1 is respectively arranged with drawing oil cylinder 4, described drawing oil cylinder 4 is vertically installed in the opening of U-shaped frame 1 sidewall, the movable end of described drawing oil cylinder 4 is arranged upward, it is respectively arranged with pulley 5 on the movable end of two described drawing oil cylinder 4, the steel wire rope 6 for towing bracket 3 it is wound with respectively on two described pulleys 5, the upper surface of the sidewall of U-shaped frame 1 is fixed in one end of described steel wire rope 6, the other end of described steel wire rope 6 is arranged on support 3.

Being provided with hole for hoist 7 on described support 3, described hole for hoist 7 is two, is symmetricly set in the base rear end of support 3.

The both sides of the upper surface of described stent bearing plank 2 are respectively arranged with roller 8, and the quantity of described roller 8 is multiple, symmetrical and be distributed in the both sides of stent bearing plank 2 upper surface uniformly, the width being smaller than support 3 between roller 8 described in symmetrical both sides.

The opening part of described U-shaped frame 1 is provided with for the added hang plate 9 of support 3.

Concrete operation method:

First fortune unwheeling is moved to support 3, then start to holder orientation, until hang plate 9 is moved the lower section to support 3, now support 3 tilts upward due to the effect of hang plate 9, then steel wire rope 6 is connected with hole for hoist 7, start drawing oil cylinder 4, the rear portion of support 3 is gradually lifted while upwardly extending by drawing oil cylinder 4, and support 3 is become level from inclination, while support 3 is lifted, traction due to steel wire rope 6 rake angle direction, support 3 can gradually move in U-shaped frame 1, owing to being provided with roller on stent bearing plank 2, therefore support 3 is easy to mobile in the horizontal direction, when support 3 is level by traction, support 3 is in the horizontal direction completely in U-shaped frame.

Above in conjunction with accompanying drawing, embodiments of the invention are explained in detail, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to various changes can be made on the premise of without departing from present inventive concept.
