Description
Technical field
The utility model relates to winning equipment, the safety device in the uncovered zone of fully-mechanized mining working elevating conveyor and front and rear portions drag conveyor head lap-joint particularly, the totally-enclosed telescopic safety device of promptly a kind of elevating conveyor.
Background technology
Elevating conveyor is in the normal operation process; Because elevating conveyor is in work plane front and rear portions drag conveyor head and reprinting place of elevating conveyor overlap joint; In the working surface production process between two heads and and the high shrouding of elevating conveyor between the elevating conveyor inboard uncovered; There is unsafe factor during the equipment operation, possibly the life accident occurs because of the running device totally-enclosed protection of being unrealized.
Summary of the invention
The utility model provides a kind of elevating conveyor simple in structure, esy to use, safe and reliable totally-enclosed telescopic safety device in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
The totally-enclosed telescopic safety device of the elevating conveyor of the utility model; Its special character is: comprise can before and after the totally-enclosed slide plate that slides; Its cross section is the L shaped of Rotate 180 °; Its horizontal component is slidingly mounted between closed cover and the following closed cover, and it vertically partly is positioned at the spillplate outside of elevating conveyor, and its drive unit is installed in down on the closed cover.
Described drive unit is a hydraulic jack, and it is installed in down on the closed cover, and between last closed cover and following closed cover.
The described closed cover of going up is fixed as one through connector at left end with following closed cover; There is the slideway that supplies totally-enclosed cover plate horizontal component left end to slide on the connector right side; Totally-enclosed slide plate horizontal component right part has downward slide rail, and following closed cover right part has the support member that makes progress that supplies slide rail to slide.
The beneficial effect of the utility model is:
1, after the utility model is used; Drag conveyor head uncovered realization in front and back is totally-enclosed; The operating personnel can get on the elevating conveyor in elevating conveyor normal operation process and work above the closed cover, and can not fall in the elevating conveyor, for the staff provides a working platform; Not only make operation convenient, also ensured operating personnel's safety.
2, this device adopts the hydraulic control advanced technology.Between the elevating conveyor on-stream period, through operation hydraulic control valve group, totally-enclosed slide plate stretches out and carries out security protection; After elevating conveyor shut down, staff's totally-enclosed slide plate of withdrawing can get into elevating conveyor then and handle related work.
3, this device all seals the outer uncovered zone of elevating conveyor of front and rear portions drag conveyor head, and the part dust gets into the inside, closed area in the coal stream, can't be diffused among personnel's working environment, has played the effect of the secondary coal dust of indirect minimizing.
4, hydraulic control valve group of this device and feed flow, liquid back pipe road are fixed on the side elevating conveyor spillplate of sidewalk, are convenient to operation, maintenance.
5, this device personnel that eliminated are strayed into the potential safety hazard that causes the accident in the elevating conveyor, thereby have avoided having guaranteed the production time because the production personal, that equipment breakdown causes is incured loss through delay, and have improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, closed cover on 1,2 times closed covers, 3 totally-enclosed slide plates, 4 slideways, 5 spillplates, 6 vertical parts, 7 slide rails, 8 support members, 9 connectors, 10 support bars.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.
The totally-enclosed telescopic safety device of the elevating conveyor of the utility model; Comprise can before and after the totally-enclosed slide plate 3 that slides; Its cross section is the L shaped of Rotate 180 °; Its horizontal component is slidingly mounted between closed cover 1 and the following closed cover 2, and its vertical part 6 is positioned at spillplate 5 outsides of elevating conveyor, and its drive unit is installed in down on the closed cover.Described drive unit is a hydraulic jack, and it is installed in down on the closed cover, and between last closed cover and following closed cover.The described closed cover 1 of going up is fixed as one through connector 9 at left end with following closed cover 2; There is the slideway 4 that supplies totally-enclosed cover plate horizontal component left end to slide on the connector right side; Totally-enclosed slide plate horizontal component right part has downward slide rail 7, and following closed cover right part has the support member that makes progress 8 that supplies slide rail to slide.
The totally-enclosed telescopic safety device of the elevating conveyor of the utility model adopts hydraulic principle, through hydraulic control valve group control hydraulic jack.Hydraulic jack is a kind of through hydraulic principle and the control of hydraulic control valve group, is widely used in the equipment that equipment and weight move.The spillplate 5 of following closed cover 2 right-hand members and the elevating conveyor below it is fixed as one, and there is turning to the right the spillplate lower end, and turning and support bar 10 lower ends are fixed, and post upper and last closed cover 1 are fixing.The vertical part 6 of totally-enclosed slide plate 3 is between spillplate 5 and support bar 10.
The utility model mainly is made up of hydraulic jack, last closed cover, following closed cover, the processing such as (being expansion plate) of totally-enclosed slide plate.This device (is installed between the upper and lower closed cover through utilizing hydraulic jack; Take root in following closed cover) slip on slideway 4 and support member 8 of the totally-enclosed slide plate 3 of drive; Guarantee that the uncovered zone of elevating conveyor is all sealed outside the front and rear portions drag conveyor head, realize the function of security protection.Hydraulic control valve group and feed flow, the liquid back pipe road of controlling this device are fixed on the side elevating conveyor spillplate of sidewalk, are convenient to operation, maintenance.After the staff starts elevating conveyor; Be fixed on the hydraulic control valve group (the control hydraulic jack is flexible) on the side elevating conveyor spillplate of sidewalk through operation; With the uncovered zone sealing of the outer elevating conveyor of front and rear portions drag conveyor head, personnel may stand in totally-enclosed slide plate and went up work of treatment face head zone related work on the closed cover this moment.After elevating conveyor is shut down, staff's totally-enclosed slide plate of can withdrawing, and get into maintenance in the elevating conveyor, change work such as scraper plate, chain.
