Abstract
The utility model relates to the mobile step being applicable to underworkings, comprises support belt, and be disposed in an evenly spaced relation in the step on support belt, step is fixedly connected with support belt by fastening bolt.The utility model, can be convenient to the gug that opens a hole, stop potential safety hazard, reduces cost of production; When other ramps need, and can the step temporarily do not used be moved on the ramp of emergency, not need the time of at substantial and manpower to carry out new ramp and arrange, guarantee workman up and down ramp that can be safe in time.
Description
Technical field
The utility model relates to the apparatus field of underground coal mine, particularly relates to the mobile step being applicable to underworkings.
Background technology
During down-hole in colliery is produced, in the tunnel of down-hole, the some places gradient is comparatively large, must arrange step, so that staff walks and carries material on ramp; But there is projection in down-hole because the pressure of both sides, tunnel often can cause comparatively greatly bottom tunnel; and the tunnel being provided with step occur the end convex after; step is caused to damage; need often cleaning, and ramp, down-hole inconvenient maintenance, the time of frequent at substantial and manpower; if but can not on-call maintenance, when material up and down ramp is especially carried in workman's walking, easily produce security incident.
Summary of the invention
For the defect of prior art, the utility model proposes the mobile step being applicable to underworkings, can the gug that opens a hole be convenient to, stop potential safety hazard, reduce cost of production.
For achieving the above object, the utility model proposes the mobile step being applicable to underworkings, comprise support belt, be disposed in an evenly spaced relation in the step on support belt, step is fixedly connected with support belt by fastening bolt.
That described support belt is rectangle and with ramp with the use of belt.
The rectangular triangle in cross section of described step, step adopts the material of wood, and the hypotenuse of step profile section is fixed by fastening bolt and support belt.
Beneficial effect
The utility model is by the wooden step installed on the support belt that arranges and support belt, when needing, the support belt being provided with wooden step is layered on ramp, during the ramp needing cleaning protruding, support belt is taken away, support belt is repaved after having cleared up, can convenient construction timely, avoid workman and occur unexpected security incident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. support belt, 2. step, 3. ramp, 4. fastening bolt.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model uses the rectangle belt mated with ramp, tunnel 3 as support belt 1, uses wooden step 2, makes the wooden length of step 2 and being used in combination of ramp, down-hole 3, the rectangular triangle in cross section of wooden step 2; The hypotenuse in step 2 cross section is fixedly connected with belt by fastening bolt 4, and on belt and wooden step 2, first all arrange the circular hole mated with fastening bolt 4, on each step 2, uniform intervals arranges multiple circular hole, preferably, step 2 is arranged four circular holes.Step 2 is fixedly connected with belt by fastening bolt 4, and step 2 is according to the length of belt, and on belt, uniform intervals is equipped with multiple.Be laid on by the belt being provided with step 2 on ramp, down-hole 3, workman just can up and down ramp easily, there is projection in the middle of ramp, down-hole after, belt is moved, only need, by after the cleaning of the part of projection, again the belt with step 2 to be laid on ramp, down-hole, just to complete housekeeping.When other ramps need, can also the belt with step 2 temporarily do not used be moved on the ramp of emergency, do not need the time of at substantial and manpower to carry out new ramp to arrange, guarantee workman up and down ramp that can be safe in time, avoids occurring security incident.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
