[0045] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the protection scope of the present application.

[0046] In combination Figures 1-7 , the screw motor carrying device for underground coal mine drilling construction of the present application is provided with a transport frame 1, two rotary assemblies 2 are symmetrically connected to the middle part of the transport frame 1; one lifting assembly 3 is hung from each rotary assembly 2; a clamping assembly 4 is arranged at the bottom of the transport frame 1 and is perpendicular to the lifting direction of the lifting assembly 3, the lifting direction of the lifting assembly 3 refers to the axial direction of the screw motor 6 loaded thereon, that is, the arrangement direction of the clamping assembly 4 is perpendicular to the axial direction of the screw motor 6. The transport frame 1 is used to vertically lift the screw motor 6 to a certain height and carry it to another place under the pushing of manpower; the lifting assembly 3 is used to connect the screw motor 6 and the transport frame 1; the clamping assembly 4 is used to clamp the screw motor 6, mainly used for complex road conditions such as rough and uneven road surface and large slope, so that the connection between the screw motor 6 and the transport frame 1 is more firm, when the road condition is good, the transport frame 1 and the lifting assembly 3 can also complete the carrying. The screw motor 6 of the present application is arranged at the symmetric axis position of the transport frame 1, which can greatly increase the stability of the vehicle body during carrying, solves the technical problem of short-distance carrying of the screw motor, uses the lever principle to lift the screw motor to a certain height, and uses the vehicle body and wheels to carry, which is simple to operate; the present application does not need other power sources, uses the lever principle to lift the screw motor and control the wheel group to rise, which is convenient to use.

A rectangular track is arranged in the lower middle part of the right side of the transfer frame 1, and the third cross beam 14 can slide in the track. Two groups of first springs 13 are arranged between the third cross beam 14 and the lateral connecting rod 15, and the elastic force of the first springs 13 pushes the third cross beam 14 to one end of the rectangular track under no external force. The rotating assembly 2 is installed on the third cross beam 14 and the first cross beam 11, and the rotating assembly 2 can rotate around the axis of the third cross beam 14 or the first cross beam 11.

During the lifting or lowering of the screw motor 6, the transfer wheel frame 5 does not bear the weight of the transfer frame 1 and the screw motor 6, and the transfer frame 1 will not slide along the ground due to the force generated by the lever 7 lifting or lowering the screw motor 6, making the lifting or lowering process of the screw motor 6 more stable. When transferring the screw motor 6, the transfer wheel frame 5 supports the entire upper weight, and the screw motor 6 is transferred by the rolling of the rollers.

The pin hole in the fixed plate 142 cooperates with the pin hole 23 in the rotating assembly 2 to limit the rotating assembly 2.

[0049] In combination Figure 4In the embodiment of the present disclosure, the rotating assembly 2 is provided with a body, a shaft sleeve 24 is arranged in the middle of the body, and a plurality of pin holes 23 are arranged around the shaft sleeve 24; a first lever socket 21 is arranged at the top of the body, and a lifting ring 25 is fixedly arranged at the lower part. The shaft sleeve 24 in the rotating assembly 2 is sleeved on the rotating shaft 143, and the rotating assembly 2 can rotate around the rotating shaft 143; four pin holes 23 are arranged in the rotating assembly 2, and a pin can be inserted into any one of the four pin holes 23 and a pin hole in the fixed plate 142 together; the pin is inserted into different pin holes 23 to position the rotating angle of the rotating assembly 2, and further control the lifting height of the screw motor 6. In order to facilitate two people to turn over the rotating assembly 2 at the same time, a second lever socket 22 is arranged vertically with the first lever socket 21 on the body, and both can be used for inserting a lever 7 to control the rotation of the rotating assembly 2. The lifting ring 25 is fixedly connected in the rotating assembly 2, and a gap is arranged at the upper part of the lifting ring 25 for hanging a lifting rope 31.

[0050] In combination Figure 5 In the embodiment of the present disclosure, the lifting assembly 3 is provided with a lifting rope 31, a hook 32 is arranged on the lifting rope 31, and a lifting ring 33 is arranged in hanging connection with the hook 32.

[0051] In combination Figure 6In the embodiment of the present disclosure, the clamping assembly 4 is provided with a base 43, and the base 43 is provided with a support 42; a sliding rod 46 is connected to the end of the support 42, the other end of the sliding rod 46 is fixedly provided with a clamping plate 41, and the sliding rod 46 is sequentially sleeved with a second spring 45 and a sliding cylinder 44 from outside; the clamping assembly 4 is an axisymmetric structure with the clamping plate 41 as the center. The clamping assembly 4 is an axisymmetric structure, and two supports 42 are arranged on the upper end of the base 43. The support 42 is connected to the base 43 by a bolt. Two sliding rods 46 are arranged on the support 42, and the two ends of the sliding rod 46 are fixed to the support 42 by a nut. The sliding rod 46 is provided with the clamping plate 41, the second spring 45 and the sliding cylinder 44, and under the pre-tightening force of the second spring 45, the two clamping plates 41 form a V-shaped structure for supporting the weight of the screw motor 6; the axial length of the sliding cylinder 44 is less than the axial length of the second spring 45, and when the second spring 45 is compressed to a certain amount, the lower end of the clamping plate 41 is in contact with the sliding cylinder 44, thereby limiting the movement range of the clamping plate 41. When the clamping assembly 4 supports the screw motor 6, the surface of the clamping plate 41 with the bevel tooth groove is in contact with the screw motor 6, so as to increase the friction force between the screw motor 6 and the clamping plate 41. The movement range of the clamping plate 41 is controlled by setting the axial length of the sliding cylinder 44. If the sliding cylinder 44 is not provided, in order to achieve the use effect that the clamping plate 41 is in contact with the screw motor 6, the stiffness coefficient of the second spring 27 needs to be increased, and too large spring stiffness coefficient will cause the screw motor 6 to be difficult to be taken out of the clamping assembly 4. If the axial length of the sliding cylinder 44 is too short, the screw motor 6 will be in contact with the lower rectangular frame of the clamping plate 41, and not in contact with the bevel tooth groove surface of the clamping plate 41, thereby causing the friction force between the clamping plate 41 and the screw motor 6 to be too small, and affecting the fixing effect of the clamping assembly 4 on the screw motor 6. The bevel tooth groove is arranged on the surface of the clamping plate 41, and the bevel tooth groove increases the friction force between the screw motor 6 and the clamping plate 41, so that the screw motor 6 is fixed more firmly in the clamping assembly 4.
