In some embodiments, the above-described features of the translation member 3 and the lift assembly 6 may be configured as shown in fig. 7, 8 and 11. Referring to fig. 7, 8 and 11, the translation member 3 has a receiving groove 31 therein, the receiving groove 31 is adapted to be inserted by the support member 4, and a groove bottom of the receiving groove 31 has a through hole 32 penetrating through the translation member 3. When the translation piece 3 is arranged between the two side vertical plates 11, the opening of the accommodating groove 31 is arranged upwards, and the axial direction of the through hole 32 is parallel to the vertical direction; in the present embodiment, it can be understood that the receiving groove 31 is disposed on the upper surface of the translation member 3, and the through hole 32 is disposed through the lower surface of the translation member 3. A sleeve body 41 suitable for being inserted into the through hole 32 is integrally connected to the support member 4, and when the support member 4 is combined with the translation member 3, the sleeve body 41 penetrates through the through hole 32 from top to bottom and extends out.

The lifting assembly 6 comprises a double rod cylinder 61 and an insert 62.

The double-rod cylinder 61 is fixedly arranged on the upper surface of the base 1, the power output axial direction of the double-rod cylinder is parallel to the vertical direction, and the power output end faces upwards.

The plug-in 62 is fixedly connected to the power output end of the double-rod cylinder 61, is suitable for being inserted into the sleeve body 41 from bottom to top, and the outer peripheral wall of the plug-in 62 is connected with the inner peripheral wall of the sleeve body 41; through the combination of the plug-in 62 and the sleeve body 41, the connection relation between the double-rod cylinder 61 and the support piece 4 can be strengthened, and the pipe body can be stably driven to lift by the driving of the double-rod cylinder 61.

By adopting the technical scheme, the stability of the lifting and descending process of the pipe body is improved by utilizing the stable driving of the double-rod cylinder 61 and the structural strength of the combined structure of the plug-in unit 62 and the sleeve body 41, and the separation phenomenon between the pipe body and the supporting piece 4 is avoided.

In some embodiments, the structure shown in fig. 7 can be used between the above-mentioned feature support 4 and the movable member 3. Referring to fig. 7, when the support member 4 is fitted into the receiving groove 31, the upper surface of the support member 4 is coplanar with the upper surface of the translation member 3. The upper surface of the support 4 is fixedly connected with a non-slip mat 42, the surface of the non-slip mat 42 is used for supporting the pipe body, and the non-slip mat is made of a high-elasticity polymer material with reversible deformation performance.

By adopting the technical scheme, after the supporting piece 4 and the sliding piece 3 are combined, the anti-skid pad 42 protrudes out of the upper surface of the sliding piece 3; meanwhile, when the pipe body is placed in the anti-slip pad 42, the anti-slip pad 42 deforms adaptively, so that the pipe body can be effectively limited from rolling back and forth and translating left and right, and the stability and reliability of the combined structure of the pipe body and the support piece 4 are improved.

In some embodiments, the structure shown in fig. 1 and 3 can be used between the characteristic lateral plate 11 and the movable member 3. Referring to fig. 1 and 3, each of the side plates 11 has a guide channel 111 thereon, and the guide channel 111 penetrates the side plate 11 in the left-right direction and extends in the front-back direction. In addition, in the present embodiment, the height of the guide cavity 111 in the up-down direction is equal to the thickness of the translation element 3, so as to avoid the situation that one side or one end of the translation element 3 tilts upwards in the process of moving back and forth.

In this embodiment, since the upper surface of the supporting member 4 and the upper surface of the translation member 3 are coplanar and the non-slip pad 42 can be deformed when the supporting member 4 and the translation member 3 are combined, the combined structure of the supporting member 4 and the translation member 3 can be translated in the left-right direction to be separated from the guide channel 111. It should be noted that, in actual operation, if the deformation of the anti-skid pad 42 cannot ensure that the translation member 3 is separated from the guide channel 111, the translation member 3 may be separated from the other side plate 11 by first separating one end of the translation member 3 from the corresponding side plate 11, and then moving the translation member 3 back to the other side plate 11. In addition, during actual preparation, the vertical height of the guide cavity 111 can be designed to be slightly larger than the thickness of the translation part 3, so that the translation part 3 can slightly move relative to the side vertical plate 11, and a certain included angle is formed between the length direction of the translation part 3 and the horizontal direction.

The upper end face of the side vertical plate 11 is provided with a piece inlet hole 112, and the piece inlet hole 112 extends from top to bottom and is communicated with one end of the guide cavity channel 111; in this embodiment, since the tube starts to be conveyed from the rear end, the feeding hole 112 communicates with the rear end of the guide channel 111; further, the inlet hole 112 is provided to penetrate the side vertical plate 11 in the left-right direction, so that the end portion of the movable element 3 can pass through the inlet hole 112 from top to bottom. In this embodiment, the width of the feeding hole 112 in the front-rear direction is equal to the width of the translation member 3 in the front-rear direction, so as to ensure accurate positioning of the translation member 3 when being inserted into the guide channel 111.

By adopting the technical scheme, the end part of the translation part 3 is suitable for passing through the part inlet hole 112 and entering the guide cavity channel 111 from top to bottom so as to be suitable for moving to the other end of the guide cavity channel 111 along the length direction of the guide cavity channel 111, so that the effective limit on the movement of the translation part 3 is improved, and the stability of the mechanism in use is enhanced; moreover, when the translation piece 3 moves to the end far away from the piece inlet hole 112, the translation piece 3 is suitable for moving in the left-right direction to be separated from the two side vertical plates 11, so that the separation phenomenon at the end point of the pipe body conveying is avoided, and the stability of the mechanism in use is improved.

In some embodiments, the two ends of the above-described characteristic translation member 3 may adopt the structure shown in fig. 7 and 8. Referring to fig. 7 and 8, one end of the translation member 3 is provided with a limit plate 33, and the limit plate 33 is located at the left end of the translation member 3 and extends outwards along the end face of the translation member 3 to abut against the outer wall of one of the side vertical plates 11. And, the other end of the translation member 3 is detachably connected with a baffle 34, and the baffle 34 is used for abutting against the outer side wall of the other side vertical plate 11 to cooperate with the limit plate 33 to limit the position of the translation member 3. In the present embodiment, as shown in fig. 8, the end surfaces of the stopper 34 and the movable member 3 are detachably connected by a combination structure of bolts and screw holes.

Through adopting above-mentioned technical scheme, when translation piece 3 was in between two side riser 11, the both ends of translation piece 3 were suitable for respectively through the outside that guide cavity says 111 and stretch out to side riser 11, and limiting plate 33 and baffle 34 butt respectively the lateral surface of two side riser 11, and the removal of restriction translation piece 3 along left and right directions has improved the structural stability of this device.
