Referring to fig. 1-4, the application discloses a suspension device for a high-strength belt carrier roller for underground mining, which comprises a force application rod 100, a suspension chain 200 and a support frame, wherein the suspension chain 200 is arranged at a first end part of the force application rod 100, and a hook 201 is arranged at the lower end of the suspension chain 200; the support frame is provided on the force application rod at the rear side of the hoist chain 200.

The support frame comprises a U-shaped frame body 310 and a limiting part 320, and the middle part of the frame body 310 is connected with the force application rod 100; the limiting portion 320 is arc-shaped, and the two limiting portions 320 are respectively disposed on the two support arms of the frame body. Support the location through spacing portion to as the strong point, be connected with the bearing roller by the couple, and carry out the application of force through the application of force pole, thereby realize the dress of bearing roller and hang the operation, whole operation in-process is quick, convenient operation, construction strength are low.

In order to further improve the structural stability of the device, the limiting portion in this embodiment includes an arc-shaped rod 321, a first limiting rod 322, a second limiting rod 323, and a spring 324, where the arc-shaped rod 321 is a hollow structure; the first limiting rod 322 and the second limiting rod 323 are matched and slidably arranged at two ends of the arc-shaped rod body; the spring 324 is disposed in the arc rod 321, and the spring 324 drives the first limiting rod 322 and the second limiting rod 323 to extend outward. The design of above-mentioned structure can make the carriage just play certain centre gripping effect when supporting, when applying the effort, can keep the spacing effect of certain centre gripping, avoids spacing portion slippage, and the security among the whole operation process obtains effectual improvement.

In order to facilitate installation, the first through groove and the handle 325 which drive the first limiting rod 322 and the second limiting rod 323 are further arranged on the arc-shaped rod body 321 in the embodiment, the handle 325 is connected with the corresponding limiting rod through the first through groove, and the first limiting rod and the second limiting rod can be opened and closed through the handle, so that preliminary alignment support is facilitated.

Further, the structure can be further refined, specifically: the two arms of the frame body 310 all include a first sleeve 311 and a second sleeve 312, the first sleeve 311 and the second sleeve 312 are slidably sleeved together, a corresponding adjusting hole is formed between the first sleeve 311 and the second sleeve 312, a positioning pin shaft 313 is arranged in the adjusting hole in a matched mode, the height of the support frame can be adjusted through the design of the telescopic structure, and therefore different working condition requirements are met.

Because the operation space is limited in the pit, at the in-process of carrying the instrument, if the size is too big, it is comparatively inconvenient, but the application of force pole adopts lever principle, and the length of application of force pole is longer, and corresponding power can be less, therefore the second tip cover of application of force pole 100 in this embodiment is equipped with telescopic link 101, and the cross-section of application of force pole 100 is polygonized structure, and the hole and the application of force pole of telescopic link 101 match, and the outer wall cross-section of flexible 101 pole is circular. A second through groove is formed in the telescopic rod 101, an elastic pressing plate 102 is arranged on the second through groove, and a non-slip mat 104 or non-slip teeth corresponding to the force application rod are arranged on the lower portion of the elastic pressing plate. The telescopic rod is provided with a grab sleeve 103, and the elastic pressing plate 102 is arranged corresponding to one grab sleeve 103. In the operation process, after the pull through the telescopic link is adjusted to certain length, one of them grab gloves is held to the left hand, also grips simultaneously to the elastic pressure plate and pushes down, and the slipmat contacts with the application of force pole this moment, avoids sliding relatively between telescopic link 101 and the application of force pole 100, plays stable effect, and another grab glove is grabbed to the right hand, pushes down, accomplishes the dress of bearing roller and hangs work.

While the above description has described in detail the preferred embodiments for carrying out the invention, it should be understood that these embodiments are presented by way of example only, and are not intended to limit the scope, applicability, or configuration of the invention in any way. The scope of the invention is defined by the appended claims and equivalents thereof.
