Abstract
An auxiliary device for excavating a groove formed in an I-shaped steel beam. Which comprises a raking head, a raking rod and a raking trouser; wherein the front end of the raking bar is connected with the upper end of the raking head through the raking trousers. Compared with the prior art, the utility model provides an auxiliary device for excavating I-steel crossbeam sets up the slot's beneficial effect is: can dig railway ballast and soil layer below the railway fast, like this, under the prerequisite of guaranteeing existing circuit driving safety, reach the purpose that the I-steel crossbeam of excavation set up the slot fast among the circuit strengthening process for construction speed, and the operation process is simple nimble, and the security is higher, has reduced the I-steel crossbeam of excavation and has set up constructor's in the slot excavation process quantity and intensity of labour, and then reduce cost.
Description
Technical Field
The utility model belongs to the technical field of railway engineering construction professional equipment, especially, relate to an auxiliary device for excavating I-steel crossbeam sets up the slot.
Background
At present, with the rapid development of national economy, infrastructure construction of each large city is expanded in a large area, the original railway becomes a ground obstacle for expanding the development of the city, the existing urban road cannot meet the requirement of the development of the city, the bridge construction of the underpass railway becomes a normal state, and the top bridge becomes the most common construction method for passing through the railway in the city.
In order to ensure the safe and normal operation of the railway, the top bridge must be constructed on the premise of ensuring the minimum influence on the railway operation in the shortest time. Existing line reinforcement has been widely used in top bridge construction as a technical assurance measure. At present, each construction unit of railway engineering still adopts a track reinforcing system of a fastening rail and an I-shaped steel longitudinal beam when carrying out top bridge construction. The I-shaped steel cross beam is arranged under the existing line, a groove needs to be dug out under the existing line before the I-shaped steel cross beam is arranged, and then the I-shaped steel cross beam penetrates into the groove. Because the weight of the I-shaped steel beam is large, and no special tool for arranging the groove is excavated, a large amount of time, manpower and material resources are needed in the process, the construction cost is high, and the speed is low, so that the method cannot meet the requirement of the construction progress under the conditions of large engineering quantity and short construction period.
In order to better ensure the firmness and safety of the existing line reinforcement and ensure the construction period, the I-shaped steel beam crossing the existing line must be completed safely and quickly.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model aims to provide an auxiliary device of simple structure, operation swiftly just can accelerate excavation I-steel crossbeam operating speed.
In order to achieve the purpose, the auxiliary device for excavating the I-shaped steel beam arrangement groove provided by the utility model comprises a raking head, a raking rod and a pair of raking trousers; wherein the front end of the raking bar is connected with the upper end of the raking head through the raking trousers.
The raking head adopts an inverted isosceles triangle steel plate, the raking rod adopts a wood rod, and the front end of the raking rod is connected to the middle part of the upper end of the raking head through raking trousers.
The axis of the derrick mast is vertical to the derrick mast.
The length of the bottom edge of the raking head is 20cm, and the length of the waist is 25 cm.
Compared with the prior art, the utility model provides an auxiliary device for excavating I-steel crossbeam sets up the slot's beneficial effect is: can dig railway ballast and soil layer below the railway fast, like this, under the prerequisite of guaranteeing existing circuit driving safety, reach the purpose that the I-steel crossbeam of excavation set up the slot fast among the circuit strengthening process for construction speed, and the operation process is simple nimble, and the security is higher, has reduced the I-steel crossbeam of excavation and has set up constructor's in the slot excavation process quantity and intensity of labour, and then reduce cost.
Drawings
Fig. 1 is a schematic structural view of an auxiliary device for excavating a groove formed in an i-steel beam provided by the present invention;
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the auxiliary device for excavating the groove formed in the i-steel beam provided by the present invention comprises a raking head 1, a raking rod 2 and raking trousers 3; wherein the front end of the raking bar 2 is connected with the upper end of the raking head 1 through a raking trouser 3.
The raking head 1 is an inverted isosceles triangle steel plate with the thickness of 0.2cm, the raking rod 2 is a wood rod, and the front end of the raking rod 2 is connected to the middle of the upper end of the raking head 1 through raking trousers 3.
The axis of the derrick mast 2 is vertical to the derrick mast 1.
The length of the bottom edge of the raking head 1 is 20cm, and the length of the waist is 25 cm.
Will now the utility model provides an application method for excavating auxiliary device that I-steel crossbeam set up the slot explains as follows:
firstly, a constructor holds the rear end of the derrick mast 2 by hands, then uses the lower part of the derrick mast 1 to take off the ballast and the rail bottom soil, and then puts the ballast and the rail bottom soil into a leather bag to be transported out of a line. Because the digging head 1 is in a triangular shape, soil is conveniently cleaned, and time and labor are saved. The auxiliary device not only can utilize the advantages of pickaxe raking, but also can rapidly convey away ballast and rail bottom soil under the existing line, so that the number and labor intensity of constructors in the process of penetrating the I-shaped steel beam into the groove can be greatly reduced, the operation process is simple and flexible, and the construction speed and the cost can be accelerated. In addition, the equipment has a simple structure, so the cost is extremely low.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
