Detailed Description

The invention will be further elucidated and described with reference to the drawings and embodiments. The utility model discloses in the technical characteristics of each embodiment under the prerequisite that does not conflict each other, all can carry out corresponding combination.

As shown in fig. 1-3, for the earthwork transportation apparatus suitable for sinking tunnel portal construction provided in a preferred embodiment of the present invention, its main components include a fixed chassis 1, a rotating base 2, a cross brace 3, a suspension rod 4, a winch 5, a support rod 6 and a counterweight 7. The equipment is mainly suitable for heavy object hoisting construction of fields with hole forms such as various manual hole digging piles, open caisson and the like. The equipment device places core devices such as the motor and the balancing weight on the lateral part of the opening, transports earthwork to the outside of a field through the rotatable chassis, and reduces the potential safety hazards of operating personnel in a pile hole and an open caisson. The specific structure of the apparatus is described in detail below.

The rotating base 2 is a round base with a fixed bottom and a rotatable top surface, and a large number of finished products can be directly realized by using products sold in the market in the prior art. The horizontal rotation angle range of the rotating base 2 is 360 °. The rotating base 2 may be an automatic rotating base or a manual rotating base as long as rotation can be achieved. The bottom of the rotating base 2 is erected on at least 1 cross brace 3, the two ends of each cross brace 3 are both extended outwards relative to the rotating base 2, and the supporting range of the rotating base 2 can be expanded by the cross braces 3. If the angle of the suspender 4 is adjusted to the farthest distance and still does not meet the transportation requirement, the device can be supported above the hole by using the cross brace 3 under the fixed chassis. The fixed chassis 1 is fixed on the rotating base 2 and can horizontally rotate along with the rotating base 2.

One end of the suspender 4 is hinged at the front end of the fixed chassis 1, the other end is fixed with a pulley, and the surface of the pulley can bypass a lifting rope for lifting a heavy object so as to reduce the resistance of the lifting rope in the lifting process. The front part of the suspender 4 is supported on the fixed chassis 1 through the supporting rod 6, and the suspender 4, the supporting rod 6 and the fixed chassis 1 form a triangular support, so that the suspender 4 and the fixed chassis 1 form an upward inclined hoisting angle. The size of the hoisting angle can be adjusted according to actual construction requirements, so that the connecting position of the suspender 4 and the supporting rod 6 can be detachably fixed in order to adapt to the adjustment of the hoisting angle. In this embodiment, the connection position of the two is temporarily fixed by the pin 8, when the angle needs to be adjusted, the pin 8 can be detached, and then the length of the support rod 6 can be adjusted. The supporting rod 6 can be set into a telescopic rod or a multi-section splicing form, so that the length of the supporting rod can be conveniently adjusted by dismounting, and the transportation capacity of the equipment device can be furthest guaranteed

In addition, in order to prevent the equipment from overturning, a plurality of balancing weights 7 are placed at the tail part of the fixed chassis 1, heavy pressure is applied to the tail part of the equipment, the gravity of a heavy object in the hoisting process is balanced, and the number of the balancing weights is balanced as required. In order to ensure the stability of the equipment as much as possible, the rotating base 2 extending out of the tail part of the fixed chassis 1 and the balancing weight 7 are placed on the fixed chassis 1 outside the rotating base 2.

The power for transporting the heavy object is provided by a hoist 5 which is mounted on the fixed chassis 1. One end of the lifting rope is wound on the winch 5, and the other end of the lifting rope is suspended downwards after bypassing the pulley at the top of the suspender 4 and is used for hanging the object to be lifted. The lifting rope can adopt a steel wire rope with the strength meeting the requirement.

The particular form of installation of the earth moving equipment may be different for different construction scenarios.

When constructing the small diameter entrance to a cave such as manual hole digging pile, then can install equipment in the subaerial of entrance to a cave lateral part, its fixed chassis 1, rotating base 2 can all be arranged in subaerial, perhaps the tip a little cantilever type is unsettled in the entrance to a cave top, relies on balancing weight 7 at rear to play balanced stable effect. When the device works, objects such as underground earthwork and the like are hoisted to the upper part of the ground through the rotation of the motor by the steel wire rope and the pulley at the front end of the suspender and the steel wire rope, and then the rotating base 2 transfers the hoisted objects to the target position of the ground through horizontal rotation to finish transportation. In this case, no cross brace may be required, and one form of apparatus is shown in fig. 4.

When constructing great entrance to a cave of diameter such as open caisson, install equipment on the ground of entrance to a cave lateral part, even the tip a little cantilever type is unsettled in the entrance to a cave top, probably also can't satisfy the jib and lift by crane the requirement of scope, need carry out span extension with the help of stull 3. At this time, the swivel base 2 may be erected above the opening by one or more wales 3 so that the boom 4 can be extended to a target position. In view of the stability of the apparatus, two parallel and spaced wales 3 are preferably provided. When the device works, objects such as underground earthwork and the like are hoisted to the upper part of the ground through the rotation of the motor by the steel wire rope and the pulley at the front end of the suspender and the steel wire rope, and then the rotating base 2 transfers the hoisted objects to the target position of the ground through horizontal rotation to finish transportation. One form of apparatus is shown in figure 1.

Therefore, the number of the wales 3 can be increased or decreased according to actual needs because construction requirements are different in different scenes. The stull 3 can be fixed through welding or detachable mode with rotating base 2, if to the equipment that often needs to switch different construction sites, preferably adopt detachable mode fixed. The cross brace 3 can be made of channel steel or I-steel.

The above-mentioned embodiments are merely a preferred embodiment of the present invention, but it is not intended to limit the present invention. Various changes and modifications can be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, all the technical schemes obtained by adopting the mode of equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
