Description

Technical Field

[0001] This utility model relates to the field of shaft construction technology, and more specifically, to a concrete pouring and ash distribution device for shafts. Background Technology

[0002] The mining industry is gradually shifting from surface to underground operations and from shallow to deep construction, with vertical shaft construction exceeding 1,000 meters becoming the mainstream. For ultra-deep vertical shafts, in order to meet the requirements of rapid and safe concrete pouring, each form of concrete needs to be lowered from the shaft opening through a mortar hopper to the lower flared end of a three-layer hoisting platform. Then, the concrete is transported through the bottom of the mortar hopper to the mortar distributor, and finally, the concrete is delivered to the pouring position via a steel wire hose at the bottom of the mortar distributor.

[0003] The ash separator currently in use lacks a supporting structure. During use, the ash separator needs to be suspended from the column of the hanging platform by steel wire rope. When discharging ash, the ash separator often shakes and spills, which brings certain risks and instabilities to the concrete pouring construction. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a vertical shaft concrete pouring ash distribution device to solve the problems of swaying, spillage and high risk factors in the existing technology, since the ash distributor has no supporting structure and needs to be suspended from the column of the hanging plate by steel wire rope during use.

[0005] The vertical shaft concrete pouring and ash-distributing device provided by this utility model includes an ash-distributing main structure and an adjustable support mechanism; wherein...

[0006] The ash-distributing main structure includes an ash-distributing trough and an ash-discharging pipe; an ash-discharging hole is provided at the bottom of the ash-distributing trough, and the upper end of the ash-discharging pipe is connected to the ash-discharging hole.

[0007] The adjustable support mechanism includes a base fixed to the bottom of the ash distribution trough, a first support arm and a second support arm hinged to the two opposite ends of the base.

[0008] Furthermore, a preferred structure is that the ash distribution trough is a trapezoidal structure with an opening cross-section larger than the bottom cross-section, and is formed by welding steel plates.

[0009] Furthermore, a preferred configuration is that a short connecting pipe is fixedly installed at the ash chute; the upper end of the ash chute is connected to the lower end of the short connecting pipe via a detachable connector.

[0010] Furthermore, in a preferred configuration, the upper end of the short connecting pipe is welded to the ash chute.

[0011] Furthermore, a preferred configuration is that the detachable connector is a flange.

[0012] Furthermore, in a preferred configuration, the number of ash chute holes is at least two, and each ash chute hole is connected to an ash chute pipe.

[0013] In addition, a preferred structure is that the base is welded and fixed to the bottom of the ash distribution trough, and a ash chute through hole is provided on the base corresponding to the ash chute hole.

[0014] Furthermore, a preferred configuration is that the first support arm is hinged to the end of the base via a first shaft mechanism; and / or, the second support arm is hinged to the end of the base via a second shaft mechanism.

[0015] Furthermore, a preferred structure is that the first shaft mechanism includes a first bearing seat disposed on both sides of the upper end of the first support arm, a first bearing disposed inside the first bearing seat, a first hinge lug disposed at the end of the base, and a first hinge shaft passing through the first hinge lug.

[0016] The two ends of the first hinge shaft are respectively located inside the first bearing on both sides of the upper end of the first support arm.

[0017] Furthermore, a preferred structure is that the second shaft mechanism includes a second bearing seat disposed on both sides of the upper end of the second support arm, a second bearing disposed inside the second bearing seat, a second hinge lug disposed at the end of the base, and a second hinge shaft passing through the second hinge lug.

[0018] The two ends of the second hinge shaft are respectively located inside the first bearing on both sides of the upper end of the second support arm.

[0019] As can be seen from the above technical solution, the vertical shaft concrete pouring ash-distributing device provided by this utility model, by adding an adjustable support mechanism to the main structure of the ash-distributing device, can reliably support the ash-distributing trough by simply adjusting the hinge angle between the first and second support arms and the base fixed at the bottom of the ash-distributing trough according to the space conditions on site. It has stability and flexibility; it avoids the instability and easy scattering of the ash-distributing device when the concrete is transported during shaft construction. Moreover, through the structural design of the first and second support arms, the lower ends of the first and second support arms can be fixed on the hanging platform, avoiding the safety hazards caused by suspending the ash-distributing trough. This utility model can effectively solve the problems of existing ash-distributing devices that do not have a support structure and need to be suspended on the column of the hanging platform by steel wire rope during use, resulting in swaying, spillage, and high risk factors.
