[0024] The directions involved in the specification are all correct when the mine underground explosion -proof portable distance measuring device of the utility model works normally, are not limited to the directions when it is stored and transported, only represent relative position relations, and do not represent absolute position relations.

[0025] Embodiment one:

[0026] As Figures 1 to 4As shown in the figure, a kind of mine underground explosion-proof portable ranging device, including box 1, the mechanical counter 2 being arranged in box 1, and two respectively rotatingly installed in the both sides of box 1 and with the synchronous rotation of the drive shaft of mechanical counter 2 The roller 3, the rear end of box 1 is detachably installed with connecting plate 4, the rear end of connecting plate 4 is bent upwards, and the rear end of connecting plate 4 is detachably installed with push rod 5.

[0027] Wherein, the front end of connecting plate 4 is installed on box 1 by bolt and nut, and bolt passing hole is formed on box 1 and connecting plate 4.

[0028] When using, by roller 3 walking, the drive shaft of mechanical counter 2 is synchronously rotated, the drive shaft drives each encoding wheel in mechanical counter to rotate, and the counting function is realized.The utility model can meet the requirement of irregular shape distance measurement of mine, is applicable to the measurement of the length of irregular shape such as circle, semicircle and triangle in underground, realizes the place where meter cannot be directly measured, saves measurement time, and improves the labor efficiency of operating personnel.The roller 3 is provided with two, and the stability of ranging device walking can be measured.The setting of connecting plate 4 can facilitate the connection of box 1 and push rod 5, and the replacement of push rod 5.

[0029] Wherein, the drive shaft of mechanical counter 2 can be coaxially connected with the rotating shaft 10 of two rollers 3 at both ends respectively, the drive shaft and rotating shaft 10 can be connected by shaft coupling, or the roller 3 can be directly fixed and sleeved on the drive shaft of mechanical counter 2.Of course, the driving gear can be sleeved on the rotating shaft 10 of roller 3, and the driven gear meshing connection with the driving gear is sleeved on the drive shaft of mechanical counter 2, so that the drive shaft of mechanical counter 2 and the rotating shaft 10 of roller 3 are drivingly connected.

[0030] As a preferred case of the embodiment, the front end of push rod 5 is fixedly connected with connecting seat 6, connecting seat 6 includes vertical plate 60 fixedly connected on push rod 5 and two horizontal plates 61 with rear end fixedly connected on vertical plate 60, the rear end of connecting plate 4 is inserted between two horizontal plates 61, bolt through hole is formed on horizontal plate 61 and connecting plate 4, locking bolt 62 passes through bolt through hole, and the upper end of locking bolt 62 is screw-mounted with locking sleeve 63 abutting on horizontal plate 61, and the upper end of locking sleeve 63 is provided with plum blossom-shaped boss 630.Specifically, connecting seat 6 is welded and connected on push rod 5, and horizontal plate 61 and vertical plate 60 are welded and connected.The setting of connecting seat 6 can facilitate the installation of push rod 5 on connecting plate 4, the setting of plum blossom-shaped boss 630 can facilitate the tightening and loosening of locking sleeve 63, and further facilitate the disassembly of push rod 5.

[0031] Furthermore, a groove 631 is provided on the plum blossom-shaped boss 630, and a locking nut 64 is screwed onto the locking bolt 62 and tightened into the groove 631. The setting of the locking nut 64 and the tightening of the locking nut 64 into the groove 631 can prevent the locking sleeve 63 from loosening, and prevent the push rod 5 from being pushed for a long time, which would cause the locking sleeve 63 to loosen, resulting in the push rod 5 shaking and affecting the use of the ranging device.

[0032] Example 2:

[0033] like Figures 1 to 6 As shown, as a further improvement to Embodiment 1, rotating shafts 10 are rotatably mounted on both sides of the housing 1. Rollers 3 are fixedly mounted on the rotating shafts 10. A limiting plate 11 located between the rollers 3 and the housing 1 is fixedly connected to the rotating shaft 10. A sliding plate 12 is slidably mounted on the housing 1. Pressure blocks 13 capable of pressing against the two limiting plates 11 are fixedly connected to both sides of the sliding plate 12. Rope threading plates 14 are fixedly connected to both sides of the sliding plate 12. An elastic mechanism for driving the sliding plate 12 to move toward the housing 1 is installed on the housing 1. The ranging device also includes a pull rope 16. The two ends of the pull rope 16 are respectively tied to the rope threading holes 15 of the two rope threading plates 14. A rear rope hook 50 is provided on the push rod 5. When the pull rope 16 hooks the rear rope hook 50, the pressure block 13 moves away from the limiting plate 11. Specifically, the limiting plate 11 is welded to the rotating shaft 10, the pressure block 13 is welded to the sliding plate 12, and the rope threading plate 14 is welded to the sliding plate 12. When the distance measurement is completed, the pull rope 16 can be released from the rear rope hook 50. The slide plate 12 moves toward the box 1 under the action of the elastic mechanism. The pressure block 13 presses against the limit plate 11, restricting the rotation of the limit plate 11. This prevents the roller 3 from rotating and causing inaccurate measurements when the worker lowers the push rod 5 to check the value after the distance measurement is completed.

[0034] The mechanical counter 2 can be coaxially connected to the shaft 10 of the two rollers 3 at both ends, and the drive shaft and the shaft 10 can be connected by a coupling.

[0035] Furthermore, the push rod 5 is provided with a front rope hook 51 located in front of the rear rope hook 50. The front rope hook 51 is welded to the push rod 5. The front rope hook 51 is designed so that when the pull rope 16 is released from the rear rope hook 50, the rope can be hooked onto the front rope hook 51, thus preventing the rope from falling to the ground without affecting the pressure block 13 pressing against the limit plate 11.

[0036] As a preferred embodiment, the push rod 5 is also provided with two rope guide plates 52 located in front of the front rope hook 51. The rope guide plates 52 are welded to the push rod 5. The rope guide plates 52 allow the rope to pass through the rope guide holes 53 on the rope guide plates 52 and then be tied to the rope threading plate 14.

[0037] The box body 1 is fixedly connected with a mounting plate 17, the two sides of the mounting plate 17 are fixedly connected with guide rods 18, guide holes 19 matched with the guide rods 18 are formed in the sliding plate 12, the sliding plate 12 is slidably arranged on the guide rods 18, the rear end of the guide rod 18 is provided with a limiting table 180, and the elastic mechanism is a compression spring 181 sleeved on the guide rod 18 between the sliding plate 12 and the limiting table 180. The mounting plate 17 is welded on the box body 1, the guide rods 18 are welded on the mounting plate 17, and the limiting table 180 is welded on the guide rod 18. The sliding plate 12 is mounted on the box body 1 through the guide rods 18, the guide rods 18 and the guide holes 19 are matched, and the sliding of the sliding plate 12 is guided. Through the compression spring 181, after the pull rope 16 is loosened, the sliding plate 12 moves towards the box body 1, the pressing block 13 is pressed against the limiting disc 11, and the rolling of the rolling wheel 3 is limited.

[0038] Further, the front end of the pressing block 13 is provided with an arc-shaped pressing groove 130, and the arc-shaped recess 631 is pressed against the limiting disc 11. The arc-shaped recess 631 is pressed against the limiting disc 11, so that the contact area of the pressing block 13 and the limiting disc 11 is increased, the friction is increased, and the rolling of the rolling wheel 3 is further avoided.

[0039] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
