At present, the amplitude tube clamp group of the rotary drilling rig is fixed on a hydraulic hose, and the tube clamp group is directly connected with the amplitude hose through bolts. In the working process of the rotary drilling rig, the variable amplitude hose can change from a mast-falling state to a mast-standing state, at the moment, the variable amplitude hose can generate relative motion with a certain amplitude, and as the pipe clamp group is fixedly connected with the hose, the pipe clamp group can not only cause certain limitation on the motion of the hose, but also can possibly cause forced bending of the hose, further the hose is cut, and the service life of the hose is reduced. In the prior art, there is no technical solution capable of solving the above problems in a targeted manner, and for this technical problem, it is generally adopted to increase the maintenance frequency of the hose, and at the same time, increase the replacement frequency of the hose, so as to maintain the normal working state of the hose. For the above reasons, the present invention discloses a hose clamp group device 200.
Referring to fig. 1, fig. 1 is a schematic view showing a structure of a hose clamp group device according to an embodiment of the present invention; the present embodiment provides a hose clamp assembly device 200 that includes a first clamping portion 210 and at least one second clamping portion 220 that are interconnected.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a first clamping portion according to an embodiment of the invention; the first clamping portion 210 is provided with a plurality of first mounting holes 211, and the plurality of first mounting holes 211 are used for being fixed in one-to-one correspondence with a corresponding plurality of hoses.
The second clamping portion 220 includes at least one second mounting hole 221, the second mounting hole 221 being configured to allow a corresponding plurality of hoses to be simultaneously movably passed therethrough, such that the hose located within the second mounting hole 221 is movable relative to the first clamping portion 210 under the influence of external force.
According to the hose clamp group device 200 provided in the present embodiment, the operating principle of the hose clamp group device 200 is:
the hose clamp group device 200 includes a first clamp portion 210 and a second clamp portion 220, and the first clamp portion 210 and the second clamp portion 220 are interconnected. When the first clamping part 210 is connected with a plurality of hoses to be tidied, the first mounting holes 211 of the first clamping part 210 are respectively connected with the corresponding hoses in a one-to-one correspondence manner, and when the hoses are matched with the corresponding first mounting holes 211, the outer walls of the hoses are tightly attached to the inner walls of the first mounting holes 211, so that after the plurality of hoses are matched with the corresponding first mounting holes 211, the first clamping part 210 can be relatively fixed on the plurality of hose groups.
Meanwhile, when the first clamping portion 210 is connected to and relatively fixed to a portion of the hose, another portion of the hose corresponding to the second clamping portion 220 may pass through the second mounting hole 221, and a certain restriction effect may be exerted on the portion of the hose through the second mounting hole 221, that is, the corresponding hose may move within the second mounting hole 221 relative to the first clamping portion 210, and its movement may be restricted by the second mounting hole 221.
Therefore, the hose clamp assembly device 200 can enable the hose connected with the first clamping part 210 and the hose passing through the second clamping part 220 to move relatively within a certain movement range by fixing part of the hose and limiting the movement of the rest of the hose when the hose changes from the inverted state to the upright state in the working process of the rotary drilling machine, and further can avoid the damage of the hose.
Further, in the present embodiment, in order to reduce the assembly difficulty and improve the installation efficiency, the first clamping portion 210 and the second clamping portion 220 are detachably connected when the first clamping portion 210 and the second clamping portion 220 are provided.

That is, the first clamping portion 210 is formed by combining a first pressing plate 212, a second pressing plate 213, a plurality of connecting studs 214, and a pipe clamp 215, so that the first clamping portion 210 is conveniently abutted with the hose. It should be noted that, in the use process, the first clamping portion 210 may be used alone according to different actual use situations.
In addition, as is apparent from the above description, the first mounting hole 211 for interfacing with the hose is provided in the pipe clamp body 215, so that the pipe clamp body 215 may include a first portion 216 and a second portion 217 for abutting against the first pressure plate 212 and the second pressure plate 213, respectively, when the pipe clamp body 215 is provided, and semicircular grooves 218 are provided on opposite sides of the first portion 216 and the second portion 217, respectively, and the two semicircular grooves 218 provided opposite to each other are used for forming one first mounting hole 211 when the first portion 216 and the second portion 217 are engaged. The purpose of this arrangement is to facilitate the engagement of each first mounting hole 211 with a corresponding hose. Thus, the installation efficiency is improved, and when the semicircular groove 218 is arranged, the semicircular groove 218 can be arranged according to the size parameter of the corresponding hose so that the first installation hole 211 can be matched with the corresponding hose to be tightly attached.
In the prior art, according to the arrangement mode of the hoses, a plurality of hoses can be sequentially divided into an upper hose, a middle hose and a lower hose, so that the hoses are protected, and the upper hose, the middle hose and the lower hose are provided with a certain range of movement requirements.
