Description
Technical field
The utility model relates to a kind of tool-class that in coal production and associated machines manufacturing enterprise, the coal face hydraulic support maintenance is used that belongs to, and relates in particular to a kind of maintenance tool ladder.
Background technology
Combining and adopting (putting) working surface hydraulic support is the important component part of fully-mechanized mining equipment, at first will determine during the machine of combining is supporting; Hydraulic support need reliable and effective support and the top board of controlling work plane prevent coal wall caving, the isolation goaf prevents that spoil from entering work plane, and effective work, ventilation, pedestrian, transport space are provided.Hydraulic support and coal-winning machine support the use, realize the coal mining comprehensive mechanization, solve the problem that in mechanical coal mining work, the roof timbering management lags behind coal cutting, coalings, transports coal, realize that work plane cuts, fills, transports, props up carrying out in order of technique, brought into play to greatest extent to the greatest extent the usefulness of coal mining and haulage device, make the fully-mechanized mining working mechanization degree reach 100%, make worker's work situation labour intensity, operating efficiency that essential lifting arranged.
The development of advancing by leaps and bounds along with science and technology, scientific development level, the equipment of mining industry have equally also had extraordinary development, new technology, new equipment continue to bring out, high-power, large mining height past according to geological conditions, safe and efficient development, the supporting height of hydraulic support is also constantly refreshing, at present domesticly mining height occurred developing and reached the full-seam mining support of 6.5 meters, provide technical support for the safe and efficient work face creates, realized the green condition of having created of exploiting for improving former coal recovery; But, the all hydraulic support is due to a variety of causes, such as reason of reason, pin and the jack of pipeline etc., the phenomenon of altering liquid appears leaking, affect the performance of hydraulic support, affect supporting effect, require the support maintenance personal in time support to be maintained for this reason, constantly keep support that a good state is arranged; Because the coal-face mining height increases, the post stroke alive of bracket upright post is also increasing thereupon, and like this, jack and the pipeline of changing set cap are just very difficult; Originally we adopted four legs of surface structures use to climb ladder, but due to the work plane limited space, the base plate inclination angle is large, also has transporter etc., four legs are climbed ladder and are difficult to fix, and during work, two people's staircases all are difficult to make it firm, and waste of manpower does not also reach safe effect, we through practice and gradual perfection, have developed coal face hydraulic support special tool for service ladder for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of maintenance tool ladder, solves the fixation problem of climbing ladder, and is naturally fixing, solid and reliable, and having processed seat, is that personnel can do maintenance in the above, up and down freely, flexible convenient, saved the manpower problem, without personnel's staircase, welcome by the maintenance personal.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of maintenance tool ladder comprises pole, it is characterized in that: the front end of pole is installed treadle for hook, the both sides of pole.
According to described maintenance tool ladder, it is characterized in that: the bottom socket pin pipe of described pole, pole is provided with bolt, and pin pipe is provided with pin-and-hole.
According to described maintenance tool ladder, it is characterized in that: the upper erecting tools case of described pole.
According to described maintenance tool ladder, it is characterized in that: the upper erection support of described pole, bearing upper mounting plate stool.
The utility model has the advantages of and be: solve the fixation problem of climbing ladder, naturally fixing, solid and reliable, and processed seat, that personnel can do maintenance in the above, up and down freely, flexible convenient, saved the manpower problem, without personnel's staircase, welcome by the maintenance personal.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
In accompanying drawing: 1, hook; 2, tool box; 3, pole; 4, stool; 5, bearing; 6, treadle; 7, bolt; 8, pin-and-hole; 9, pin pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of maintenance tool ladder comprises pole 3, it is characterized in that: the front end of pole 3 is installed treadle 6 for hook 1, the both sides of pole 3.According to described maintenance tool ladder, it is characterized in that: the bottom socket pin pipe 9 of described pole 3, pole 3 is provided with bolt 7, and pin pipe 9 is provided with pin-and-hole 8.According to described maintenance tool ladder, it is characterized in that: erecting tools case 2 on described pole 3.According to described maintenance tool ladder, it is characterized in that: erection support 5 on described pole 3, bearing 5 upper mounting plate stools 4.
Use principle of the present utility model is as shown in Figure 1: hook 1 is hung on pipeline, then pin pipe 9 is inserted under ground, bolt 7 spiral shells are advanced in pin-and-hole 8, can be put into instrument in tool box 2.The people can sit on and carry out maintenance work on stool 4.
1, adopt suspending way ladder to be fixed on the support of required maintenance, each support is designed with lifting eye, ladder is fixed on lifting eye, the below is a movable fixed bar that can stretch, movable fixed bar contact base plate, make the ladder of climbing to a higher point to do the circle type activity, accomplished time all fixed.
2, material: diameter is the steel pipe of Φ 25mm, and the ladder height can be according to the height design of pole 3, and we adopt is the steel pipe of 3.13 meters, does a crooked hook 1 at an end of steel pipe according to lifting eye, length 60mm, flexibility 180 degree.For convenience of the up and down, every the treadle 6 of a symmetry of 250mm processing, at, 1.7 meters of bottoms of distance steel pipe, a stool 4 is installed from steel pipe bottom, is convenient to maintenance personal's reliable maintenance aloft, in tool box 2 of design, 500mm place, distance top, be convenient to deposit maintenance tool.Be convenient to maintenance personal's storing tools, avoid what instrument of maintenance personal all hand held in, taking with oneself affects its flexibility.
3, this maintenance special-purpose ladder is through for several times perfect, reach the maintenance that the earth has facilitated the coal-face support after using, saved manpower, make the maintaining support of the single just energy of maintenance personal safety, avoided down-hole high-altitude maintenance operation user of service many, fix the state not firm, that safety factor is low, improved safety factor, solved unsafe condition of things, ensured worker's safety work, saved maintenance time and improved operating efficiency.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model all should fall into protection domain of the present utility model.
