Problems solved by technology

However, there is usually such a problem at the construction site, that is, the dust removal fan that moves forward and backward with the fully mechanized excavator is often derailed due to poor runway quality and uneven roadway floor. Once the dust removal fan derails, it will not only affect the normal operation of the dust removal fan, but also affect In the construction of fully mechanized excavation, a lot of time was wasted in dealing with the derailment of the dust removal fan. At the same time, there are also great safety hazards in the process of derailment
[0003] At present, the single-frame runway of the dust removal fan is basically connected to the tail of the second transport machine of the fully mechanized excavator through a connecting rod. The runway is uneven and straight due to irregularities and changes in roadway conditions, and the dust removal fan is easy to derail. The traditional single-wheel type cannot meet its fixed needs. It will derail when it encounters an uneven place, and sometimes it will cause rollover. , the potential safety hazard is great, and it also has a great impact on production efficiency.

Embodiment 1

[0028] Such as Figure 1-Figure 3 As shown, a dust removal fan runway stretcher anti-derailment protection device includes a stretcher 1, a splint 2 fixed on both sides of the stretcher 1, and a guard wheel 4 hinged to the splint 2 and located outside the track 3, wherein the guard wheel 4 and The lower bottom surface of the track upper bar 31 abuts against each other.

[0029] The stretcher 1 is a ship-shaped stretcher with an upward opening, and two partitions 11 are arranged in sequence along its transverse direction; the cavity surrounded by the stretcher 1 and the partitions 11 is the first cavity 111, the second cavity 112 and the first cavity from left to right. The third cavity 113, wherein the first cavity 111 and the third cavity 113 are respectively the first cavity 111 and the third cavity 113 with part of the opening covered by the splint 2, and the second cavity 112 is fixedly connected A vertical support base 12 with a fixed plate 121; in addition, the bottom o...

Embodiment 2

[0035] A method for using a runway stretcher anti-derailment protection device for a dust removal fan, comprising the following steps:

[0036] (1) the anti-derailment protection devices of the dust removal fan runway stretcher in two embodiments 1 are installed on two parallel tracks 3 successively;

[0037] (2) An "I"-shaped steel 5 is horizontally mounted on two fixed flat plates 121 and fixed with fixing pins (such as Figure 4 shown);

[0038] (3) Move the dedusting fan smoothly on the "I" shaped steel 5 that has been fixed on the fixed plate 121.

Embodiment 3

[0040] This embodiment is basically the same as Embodiment 2, and the difference is that four dust removal fan runway stretcher anti-derailment protection devices are used, two groups, the front and rear distance lengths of each group are equal to the length of the dust removal fan, and then each group Follow the steps in Example 2.

Abstract

The invention discloses a derail-proof protecting device for a dust-removing fan track stretcher. The derail-proof protecting device comprises a stretcher, clamping plates and guard rail wheels, wherein the clamping plates are fixed to the two sides of the stretcher correspondingly, and the guard rail wheels are hinged to the clamping plates correspondingly and located on the outer side of a rail.The opening of the stretcher faces upward, and a supporting seat is vertically arranged in one of the internal cavities, and at least one stretcher wheel located on the outer side of the rail are arranged at the bottom of the stretcher. The invention further discloses a using method of the derail-proof protecting device for the dust-removing fan track stretcher. The derail-proof protecting devicefor the dust-removing fan track stretcher and the using method thereof have the advantages that the structure is simple; operation is easy; derail of the dust-removing fan is effectively prevented; sliding of the stretcher wheels can be limited; and when a roadheader moves forward and backward, the derail-proof protecting device can moves forward and backward along with the roadheader, and the derail of the dust-removing fan is not caused, and therefore, normal dust removing of a dust-removing fan is not affected, good security is provided for a downhole operating environment, and meanwhile the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of anti-derailment devices, in particular to an anti-derailment protection device for a runway stretcher of a dust removal fan and a method for using the same. Background technique [0002] A large amount of dust will be generated during the construction of the fully mechanized excavator, which will cause great harm to the health of the workers on the construction site. Through the use of dust removal fan, dust can be greatly reduced. However, there is usually such a problem at the construction site, that is, the dust removal fan that moves forward and backward with the fully mechanized excavator is often derailed due to poor runway quality and uneven roadway floor. Once the dust removal fan derails, it will not only affect the normal operation of the dust removal fan, but also affect In the construction of comprehensive excavation, a lot of time was wasted in dealing with the derailment of the dust removal...
