Preferably, the main body structure is provided with parallel sliding chutes at the edge of the open area; the slider realizes horizontal displacement in the open area through the moving cooperation with the sliding groove.
Preferably, the retractable shielding component is an organ type mesh.
Preferably, the hoist is provided with a first steel cable and a second steel cable; the movable cover plate device of the hoist comprises a first slider structure for the first steel cable to penetrate through and a second slider structure for the second steel cable to penetrate through.
Preferably, each of said slides is made up of two parts; the width of each portion is less than one-half the width of the open area.
The utility model has the advantages that:
due to the structural design, the movable cover plate device is arranged at the lower side of the hoist; the characteristic that a steel cable of the hoist has horizontal displacement while moving up and down is used as the power for horizontally opening and closing the movable cover plate device, so that the movable cover plate device can automatically and adaptively cover the open area in the whole working process of the hoist, and the hidden danger problems of insanitation and unsafety in the open area in the prior art are solved.
The utility model discloses a remove apron device need not to increase extra power part, and simple structure, easy maintenance.
Drawings
FIG. 1 is a schematic diagram of a prior art structure;
fig. 2 is a schematic structural diagram of a first operating state according to an embodiment of the present invention;
fig. 3 is a schematic structural diagram of a second operating state according to an embodiment of the present invention.
The device comprises a main body structure 1, an open area 11, a slider structure 2, a slider 21, a cable hole 22, a first pulley 23, a second pulley 24, a telescopic shielding component 3, a hoist 6 and a cable 61.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 2, a specific embodiment of the movable cover plate device of the hoist of the present invention is disposed at the lower side of the hoist 6; comprising a body structure 1. An open area 11 for the steel cable 61 of the hoist 6 to pass through is arranged in the middle of the main body structure 1. A horizontally displaceable slide construction 2 is arranged in the open area 11.
The sliding block structure 2 comprises a sliding block 21 provided with a steel cable hole 22, and a first pulley 23 and a second pulley 24 respectively positioned at two sides of the steel cable hole 22. The main body structure 1 is provided with parallel sliding chutes (not shown in the figure) at the edge of the open area 11; the slider 21 achieves a horizontal displacement in the open area 11 by cooperating with the movement of the slide groove.
A telescopic shielding component 3 is arranged between the sliding block 21 and the edge of the open area 11. In this embodiment, the retractable shielding member 3 is an organ-type mesh cloth, and plays a role of moving the cover plate.
In this embodiment, the hoist 1 has two cables 6; the moving cover device thus comprises a first slider structure 2 through which a first cable 6 is passed, and a second slider structure 2 through which a second cable 6 is passed. Each slider structure 2 has a respective first pulley 23 and second pulley 24, and a corresponding cable is inserted into the cable hole 22 between the first pulley 23 and the second pulley 24.
In the above structure, in addition to the retractable shielding member 3 provided between the slider 21 and the edge of the open area 11, an accordion-type mesh cloth is also provided between the two slider structures 2.
As shown in figure 3, when the headstock gear during operation, the utility model discloses a move apron device cooperation of headstock gear and work together, the displacement is controlled in about the displacement about the steel cable about the displacement about in about, and the displacement passes through first pulley, second pulley about the steel cable, drives displacement about the slider structure to drive organ formula screen cloth open, close, realize moving the technological effect of apron.
In other embodiments, the hoist may have only one cable. At this time, the cover plate moving device only needs to be provided with one set of sliding block structures. The two sides of the sliding plate in the sliding block structure are respectively provided with organ type mesh cloth, so that the function of moving the cover plate can be realized.
After the device is used for a period, the organ type mesh cloth needs to be replaced due to various reasons such as damage and the like. But because the steel cable runs through in the steel cable hole of slider, lead to integrative slider can't dismantle, it is very difficult to change organ formula screen cloth. In other embodiments, each slider 21 is composed of a left portion and a right portion; the width of each portion is less than one-half the width of the open area. Specifically, for example, the width of the left half portion in the chute direction is smaller than one-half of the width of the open area. The slider is designed into two pieces to be spliced, and the width dimension of the slider is controlled as much as possible, so that the structural design has the advantages that: the sliding block can be taken out from the sliding groove only by rotating the half sliding block by 90 degrees in the sliding groove. Then, the old organ type mesh cloth fixed on the sliding block can be conveniently detached, the new organ type mesh cloth is replaced and fixed on the sliding block, the half sliding block with the updated organ type mesh cloth is inserted into the sliding groove and is fixed with the other half sliding block, and then normal use can be recovered.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
