Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to Figure of description, describe according to the measurement backup system of the CMS detection instrument of the utility model embodiment.The measurement backup system of this CMS detection instrument is mainly to transform measuring baseline system and mounting system, and it is time saving and energy saving that improved measurement mechanism not only sets up, and degree of safety is high, also can meet the measurement requirement under various narrow environments.
As shown in Figure 2, the mounting system of the measurement backup system of CMS detection instrument comprises cross bar (1), fore-stock, rear vertical rod (3) and fine setting lifter.
As shown in Figure 3, cross bar is used for carrying CMS detection instrument probe (8), CMS detection instrument probe (8) can be fixed on to cross bar one end, and former and later two strong points that rely on fore-stock and rear vertical rod to provide, CMS detection instrument probe (8) is delivered to goaf stope is surveyed.In order to be convenient for carrying and to install, the utility model utilizes telescopic cross bar, and cross bar adopts high-strength material to make, and requires inside and outside wall smooth, and the telescopic joint lap of splice is greater than 100mm, and single-unit length is greater than 2000mm, and total length is greater than 9000mm.
As Fig. 4 (a) with 4(b), fore-stock unitary construction is prismatoid, is the open shape of the Eight characters.Mainly comprise prismatoid that four pillars (11) surround or the foot rest of cone-shaped body, and the fixing U-shaped groove (10) in foot rest top.On base plate in U-shaped groove groove, be provided with deep-slotted chip breaker (24) (being that pipe in axial direction excises a part), deep-slotted chip breaker (24) back-off is (axial slices that is deep-slotted chip breaker overlaps with U-shaped trough floor) in U-shaped trough floor, and deep-slotted chip breaker (24) axis is vertical with U-shaped fluted shaft line.Described deep-slotted chip breaker (24) outside surface provides front support point for cross bar, when utilizing its support and lifting cross bar (1), while guaranteeing that cross bar (1) in the horizontal direction or leaning forward or during hypsokinesis direction, cross bar can be tangent with deep-slotted chip breaker (24) outside surface, avoid directly take the edge of U-shaped groove (10) one end as supporting in cross bar inclination situation, cause the unstable of support.As shown in Figure 4 (a), U-shaped groove cell body width is greater than cross bar diameter, allows cross bar to do trace adjustment and limits its setting range simultaneously, has increased the controllability of equipment.In order to strengthen the friction force of deep-slotted chip breaker (24) Yu the cross bar (1) of support rail, deep-slotted chip breaker (24) outside surface is pasted skid resistant course (13), as rubber layer simultaneously.
In fore-stock foot rest, each pillar (11) can insert bedrock surface as support, strengthens the stability of foot rest, is provided with between two brace summer (12a, 12b) between pillar, further improves the steadiness of foot rest.
Fore-stock overall height (vertical height on U-shaped groove top to ground) is below 2m, both the needs that set up surveying instrument had been met, do not contact with back (4) again, avoid front vertical rod in prior art closely to oppress back, the potential safety hazard that causes top board rubble to fall and cause.
Rear vertical rod (3) middle part is provided with gland (2), can press cross bar rear end downwards, for cross bar provides described rear support point.
