Abstract
The utility model discloses an arc trolley used for horizontally transporting penstock in a hole. The arc trolley comprises a wheel carrier, wheels which are located on a bottom of the wheel carrier and are installed on the wheel carrier and a trolley body installed on the wheel carrier. A top surface of the trolley body is a cambered surface which is cooperated with an outer wall of the penstock. By using the arc trolley of the utility model, penstock installation and transportation requirements in the hole are satisfied; a vehicle and lifting equipment are not needed to assist the transport and unloading in the hole; a circular degree of the penstock can not be out-of-round during the penstock transportation; usage is safe and high-efficient and cost is low.
Description
Technical field:
The utility model relates to a kind of transportation chassis, particularly be level transportation arc chassis in a kind of major diameter penstock hole that can be used for field such as power station.
Background technology:
At present; The penstock that the design of hydropower station pressure steel pipe, construction are generally exposed conduit formula or embedded, particularly embedded pressure piping is installed in the world and even China's genus majority, and the expansion of embedded pressure piping is dug size and considered the investment total price again; Operated by rotary motion is less than normal; So just to penstock transportation, install and brought trouble, mainly be because the hole dig size can not satisfy large lifting equipment installation, can not lift, and the tonnage of domestic embedded penstock is bigger than normal; General vehicle can't carry out hole internal pressure steel pipe transportation, special-purpose sky anchor and hoist cable also need be set just can carry out transportation in the penstock hole; So just give transportation in the penstock hole, install and brought very big difficulty.
The utility model content:
The purpose of the utility model is in order to overcome above deficiency; A kind of satisfy hole internal pressure steel pipe installation, transportation request are provided; Transportation is unloaded and is not needed vehicle, weight-lifting equipment to assist in the hole; Penstock circularity can not lost circle when guaranteeing the transport pressure steel pipe, level transportation arc chassis in the penstock hole safe, efficient, with low cost.
The purpose of the utility model realizes like this:
Level transportation arc chassis comprises wheel carrier in the utility model penstock hole, is positioned at being loaded on wheel on the wheel carrier, being loaded on the vehicle body on the wheel carrier of wheel carrier bottom, and the vehicle body end face is the cambered surface that cooperates with the penstock outer wall.
Above-mentioned vehicle body is made up of the many radian beams that are loaded on the wheel carrier parallel to each other, and the end face of every radian beam is the cambered surface that cooperates with the penstock outer wall.
The chassis dedicated track is installed in the pressure piping hole in advance; Utilize in the utility model penstock hole level transportation arc chassis vehicle body cambered surface and the penstock radian is fitted, fix, utilize interim weight-lifting equipment on penstock tube coupling handling to the utility model arc chassis; The utility model arc chassis, penstock tube coupling are as a whole at the enterprising line slip of dedicated track, until being transported to the installation position.Penstock is installed, adjustment is taken out the utility model arc chassis recycling after in place.
The utility model utilizes vehicle body arc top surface radian and perfect, the compact applying of penstock outer wall radian; Reduced the center of gravity of horizontal positioned in the penstock hole, can prevent effectively in the horizontal transportation of penstock that the circularity distortion makes penstock reliable installation in the transportation in the hole; Also reduce simultaneously the quantities of hole wall excavation, practiced thrift the project gross investment.But transportation in the direct saving penstock hole, lifting or secondary are had bad luck the correlative charges of generation, only need get final product (but and the track demolition, installation are reusable) by the requirement and the operating mode laying track of camp site.
The utility model compact conformation, dexterous convenient, it is low, reusable to be convenient to making and cost of manufacture.Behind the utility model chassis place in operation, the safety of putting down section, upward flat section penstock installation, transportation in the hole down there is good assurance, the lease expenses of saving transport vehicle, lifting appliance.The utility model is applicable in the penstock hole of any thickness of slab with caliber and transports.
