Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
As shown in fig. 1 and 2, the utility model provides a wear station dust door gear for dust excluding hood in cast tube, including curtain cloth 4, be connected with curtain cloth 4 and be used for controlling curtain cloth 4 and carry out the winding mechanism that switches with the expansion state at the roll-up state, set up in the balancing weight 8 of curtain cloth 4 lower extreme and be used for carrying out the guiding mechanism who leads to curtain cloth 4, guiding mechanism includes vertical guide bar 6 and the level that sets up on the dust excluding hood and sets up the gag lever post 5 that just is located winding mechanism one side in the dust excluding hood, guide bar 6 has the guide way that lets balancing weight 8 and curtain cloth 4 imbed.
Specifically, as shown in fig. 1 and 2, the winding mechanism includes a drum 3 rotatably disposed and a winding motor 1 connected to the drum 3, the drum 3 is parallel to a limiting rod 5, the curtain cloth 4 is connected to the drum 3, and the curtain cloth 4 passes through between the drum 3 and the limiting rod 5. Winding motor 1 is fixed to be set up on the dust excluding hood and is located the top of dust excluding hood, and cylinder 3 is the level setting, and cylinder 3 is the cylinder, and the axis of cylinder 3 is located the horizontal plane. The cylinder 3 is rotatable and sets up in the top of dust excluding hood, and the upper end and the cylinder 3 fixed connection of curtain cloth 4, the one end and the motor shaft of rolling motor 1 of cylinder 3 are connected, and rolling motor 1 operates, can drive cylinder 3 and rotate around its axis, and then can realize the roll-up and the expansion of curtain cloth 4. When the curtain cloth 4 is switched from the unfolding state to the folding state, the rolling motor 1 drives the roller 3 to rotate, the curtain cloth 4 is gradually wound on the roller 3, and the end part of the dust hood enables the door opening through which the cast pipe enters and exits to be gradually opened; when the curtain cloth 4 is switched from a furling state to a spreading state, the winding motor 1 drives the roller 3 to rotate reversely, the curtain cloth 4 wound on the roller 3 is gradually released, and the curtain cloth 4 gradually closes the door opening at the end part of the dust removing cover. When the inner grinding station is used for production, namely when the inner wall of the polyurethane pipe in the dust hood is ground, the curtain cloth 4 is in the unfolding state, the curtain cloth 4 in the unfolding state seals the door opening of the dust hood, the dust removal effect can be improved, the field environment is improved, and the health injury to field workers is avoided.
As shown in fig. 1 and 2, two parallel guide rods 6 are arranged, the two guide rods 6 are positioned on the same straight line parallel to the limiting rod 5, the guide rods 6 are positioned below the limiting rod 5, the length direction of the limiting rod 5 is parallel to the axis of the roller 3, the guide grooves are grooves extending on the guide rods 6 along the length direction of the guide rods 6, and two opposite sides of the curtain cloth 4 are respectively embedded into the guide grooves of the two guide rods 6. The balancing weight 8 is located between two guide bars 6, the lower extreme fixed connection of balancing weight 8 and curtain cloth 4, and the length direction of balancing weight 8 parallels with the length direction of gag lever post 5, and the both ends of balancing weight 8 imbed respectively in the guide way of two guide bars 6, and balancing weight 8 is used for switching to the in-process of expansion state at curtain cloth 4 by the roll-up state, relies on self gravity to stimulate curtain cloth 4 downstream. When the curtain cloth 4 is switched between the furled state and the unfolded state, the guide rod 6 can guide the counterweight block 8 and the curtain cloth 4, so that the stable lifting operation of the curtain cloth 4 is ensured.
Preferably, the height of the limiting rod 5 is smaller than that of the roller 3, the limiting rod 5 is located below the side of the roller 3, the curtain cloth 4 penetrates through the limiting rod 5 and the roller 3, the limiting rod 5 and the roller 3 are not arranged side by side and are arranged in a staggered mode in the height direction, and the curtain cloth 4 can be prevented from deviating in the lifting process.
As shown in fig. 1 and fig. 2, the dust-proof door device for the cast pipe internal grinding station dust hood of the present invention further includes a switch support 9 disposed on the dust hood and a limit switch 7 disposed on the switch support 9. Switch bracket 9 is located the lower extreme of dust excluding hood, and limit switch 7 is fixed to be set up on switch bracket 9, and limit switch 7 cooperatees with balancing weight 8, and limit switch 7 is used for detecting whether balancing weight 8 targets in place.
The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
