Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-2, the small-gradient inclined shaft concrete conveying device comprises a chute main body 1 and an enamel layer 2, wherein the enamel layer 2 is covered and bonded on the chute main body 1.
The arc that chute main part 1 is the semicircle platelike structure, offer the bolt hole 3 that two sets of chutes of being convenient for butt joint each other on the chute main part 1, in this embodiment, chute main part 1 is long 1M, nominal thickness 2.5mm, arc length 720mm, diameter 400 mm's semicircle platelike structure, M10 bolt hole 3 is reserved at four angles in both ends, adopt length 20 mm's M10 screw thread can be fixed, realize two sections chute overlap joint length 60mm, realize chute main part 1's connection and fixed. The chute main body 1 adopts a cold-rolled steel plate (Q235) with the thickness of 2.5mm to be flat through opening, shearing, punching, pickling, soaking in alkaline water, cleaning with clear water, applying enamel glaze on the chute main body in a dry mode, applying the enamel glaze for the second time after one minute, moving the chute main body to a drying room to be dried to form an enamel layer 2, starting burning after drying, burning and bonding the enamel to a steel plate after about 850 ℃ for 5 minutes, and finally pressing to form a semicircular plate structure. The concrete conveying chute has the advantages that the concrete of the inclined shaft with the small gradient of 10-18 degrees is conveyed to the concrete bin surface in a chute mode, the friction coefficient of an enamel chute is smaller in an enamel sheet or a PVC plate, the adsorption force with the surface of the concrete is smaller, the durability is better, and the concrete can flow on the small gradient slope section conveniently.
Hanging hole 3 has been seted up to chute main part one end, and the other end is provided with and is used for setting up couple 4 on hanging hole 3, and chute main part bottom sets up locating piece 5, and locating piece 5 is fixed a position accurately in the work progress, can prevent that the chute from swinging and chute long distance roll, realizes the accuracy and the fixed stability of chute location, and the front end of enamel pipeline chute reserves 3 rear ends in hanging hole of 50mm 30mm and sets up couple 4 of 40mm 25 mm. The entrance to a cave at the inclined shaft sets up the head end of the fixed enamel pipeline of enamel pipeline fixed bolster, and the chute main part from top to bottom is laid on the side wall bottom plate, and next chute main part overlap joint in last chute main part bottom, and the hanging hole 3 that adopts next chute main part and the fixed formation of hangers of last chute main part are whole during the overlap joint, and whole enamel pipeline is terminal to extend to the concrete storehouse face. Before concrete pouring, the enamel pipeline is moved or extended to a proper position, and a small amount of water is poured into the enamel pipeline from an inlet at the upper end to play a lubricating role, so that the water loss when the concrete flows is reduced, and the concrete can be conveyed to a warehouse surface.
The utility model discloses can be used to the concrete transport of the slope inclined shaft of little slope, the concrete is less to enamel chute's adhesive force and frictional force, change and realize the continuity transport at the slope inclined shaft of little slope, and enamel chute durability is better, the use cost contrast is lower, concrete transportation process is less and simple, the transport efficiency is high (the concrete volume of putting into storage) and continuous every hour, it explodes not to occupy winch hoist system influence inclined shaft drilling, can realize that inclined shaft drilling explodes and concrete lining synchronous construction, and simultaneously, quick dismouting is realized to the combination of two chute main part accessible couples and hanging hole, realize accuracy and the stability of chute location through the locating piece, installation effectiveness and result of use have been promoted greatly.
