Description

A kind of board plug type concrete acoustical barrier acoustic board hoisting device
Technical field
A kind of board plug type concrete acoustical barrier acoustic board hoisting device, it is related to railway, Highways ' sound barrier construction field, More particularly to a kind of handling of sound-absorbing barrier, lifting construction instrument.
Background technology
With the rapid development of the road constructions such as China Express Railway, its corresponding environmentally friendly auxiliary facility is also synchronously built It is the primary hand of Along Railway noise reduction using sound barrier noise reduction if noise-reducing device is the important component of environmentally friendly auxiliary facility One of section.The road noise barriers such as high-speed railway mainly divide board plug type and monoblock type, and board plug type concrete acoustical barrier has construction The advantages that difficulty is small, speed of application is fast, life cycle is long, operation maintenance facilitates, generally uses in China Express Railway construction.
The roads such as high-speed railway are concrete casing parcel sound-absorbing material with the acoustic board of board plug type concrete acoustical barrier Prefabricated block structure.Concrete casing is relatively thin, and exposed face is smooth, and structure is without hole for hoist (ring).Due to the limitation of structure in itself, Acoustic board in entrucking of dispatching from the factory, unload, in installation process, hoist cable be present and be not easy lasso trick, tear rope open, coordinate lasso trick, tear the crowbar work of rope open Tool easily damages the problem of prefabricated components, and prefabricated components breakage rate is high, speed of application is slow, particularly faces side, upper air installing operation Security risk is high.For reduce acoustic board in entrucking of dispatching from the factory, unload, the breakage rate during installation exercise, improve operating efficiency, drop Lower security risk had both facilitated hoist cable lasso trick, has torn rope open, it is necessary to design when one kind lifts, and the not special hanger of damaged member.China Patent discloses a kind of a kind of " existing railway sound barrier panel lifting appliance for installing " patent of Patent No. 201720062615, and this is Frame structure is formed by upper and lower crossbeam and linking beam, hook is set on sill, grab is set to lift sound absorption on linking beam Plate.The device ensure that the safety of lifting, but hoisting process device is not easy to install, removes, and device can not be direct by acoustic board Installation site is hung onto, faces side, upper air installing job safety risk height.
The content of the invention
The problem to be solved in the present invention is to provide one kind device in hoisting process for deficiency above and be easily installed, tear open Remove, face the high sound-absorbing barrier hoisting device of side, upper air installing job safety coefficient.Its technical scheme is as follows:
It includes back timber and the suspension ring being arranged on back timber, and its key technology is to set forearm and postbrachium at back timber both ends, Sleeve is set in the medium position perforate of forearm, hole, adjusting screw rod, adjusting screw rod one end connection limiting plate, limit are set in sleeve Position plate another side sets limited block, and limiting plate is between forearm and postbrachium.
The connected mode of the adjusting screw rod and limiting plate is that adjusting screw rod one end sets anchor head, position of being limited in the middle part of limiting plate Cap, anchor head are snapped in limited cap.
Compared with prior art, the invention has the advantages that:
1st, it sets forearm and postbrachium at back timber both ends, forms n-type notch, sleeve, sleeve are set in the middle part of forearm Adjusting screw rod is inside set, adjusting screw rod one end connection limiting plate, limiting plate is between forearm and postbrachium.In use, by " n " type card Groove is buckled on acoustic board, and limiting plate is adjusted by adjusting screw rod, and forming mounting board to acoustic board fixes, and lifting is firm, utilizes hoist cable Fasten suspension ring and carry out lifting operation, avoid crowbar instrument to the inevitable damage of acoustic board, effectively carried out finished product guarantor Shield, has saved cost, security risk is reduced in terms of power tool and construction technology two.
2nd, using n-type notch, suspender is noiseless to the left and right side of acoustic board and bottom during lifting, will directly can inhale Sound plate hangs onto installation site, hoist cable unblock when solving the problems, such as to face side, work high above the ground, tears rope difficulty open, from power tool and Two aspects of construction technology reduce security risk.
3rd, the division of suspender and acoustic board is controlled using adjusting screw rod, suspender installation, dismounting speed are fast, accelerate construct into Degree, efficiency of construction are improved.
5th, all manufacture materials are steel material, and intensity is high, wear-resistant, anti-fatigue performance is good, is reduced in itself from hoisting device Security risk during operation.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1~Fig. 7, it includes back timber 2 and the suspension ring 1 being arranged on back timber 2, and its key technology is in 2 liang of back timber End sets the forearm 3 and postbrachium 4 vertical with back timber 2, skeleton of the n-type notch as the device is formed, at the middle part of forearm 3 Position perforate, sleeve 8 being threaded in hole, adjusting screw rod 6 being set in sleeve 8, connection limiting plate 10 in the one end of adjusting screw rod 6 is spacing The another side of plate 10 sets limited block 11, and limiting plate 10 is between forearm 3 and postbrachium 4.
The connected mode of the adjusting screw rod 6 and limiting plate 10 is that the one end of adjusting screw rod 6 sets anchor head 9, the middle part of limiting plate 10 If limited cap 12, anchor head 9 is snapped in limited cap 12.
The other end installation rotating handles 5 of the adjusting screw rod 6.
Strengthening steel slab 7 is set positioned at the outside of forearm 3 on the sleeve 8.
The back timber 2, forearm 3 and postbrachium 4 are made of channel-section steel.
The present invention uses step:
Two hoisting devices are a set of, during lifting complete pairing use, be symmetrically arranged in as shown in Figure 6, Figure 7, during use Acoustic board both ends, wherein 13 be acoustic board, 14 be acoustic board preformed hole, and 15 be hoist cable.
Hoisting device is installed:Rotating handles 5 is rotated, it is symmetrical that limited cap 12 is retracted at forearm 3 → two " n " type necks It is buckled in 13 both ends of acoustic board → limited block 11 and is directed at preformed hole 14 → stubborn rotating handles 5, pushes ahead adjusting screw rod 6, make spacing The entrance acoustic board of block 11 preformed hole 14 → tighten adjusting screw rod 6, makes limiting plate 10 clamp acoustic board → lifting with postbrachium 4.
Hoisting device is removed:After acoustic board 13 is lifted on precalculated position, rotating handles 5 is twisted, retreats adjusting screw rod 6, it is spacing Block 11 exits preformed hole 14, and limiting plate 10 unclamps acoustic board → lifting with postbrachium 4, and hoisting device departs from acoustic board.
