DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] Reference Figs. 1-3The utility model provides a kind of auxiliary support for horizontal directional drilling, it is mainly composed of two pipe trailer monomers.Every pipe trailer monomer includes frame body 1, support block 3 and drive assembly.Frame body 1 is equipped with travelling wheel 2 on lower surface, so that the whole support can be flexibly moved on ground.Two frame bodies 1 are connected by detachable connection, and it is convenient to assemble and split according to actual use demand.Support block 3 is slidably connected on the upper surface of frame body 1 along horizontal direction.Concretely, the lower end of support block 3 is connected or integrally formed with sliding block 4, and the surface of frame body 1 is provided with sliding groove 5 along horizontal direction, and sliding block 4 is matched with sliding groove 5 and can slide in it.Through this sliding connection mode, support block 3 can be adjusted in position on the upper surface of frame body 1 along horizontal direction, so as to better carry pipe of different diameters.

[0030] Drive assembly is the key component for realizing the position adjustment of support block 3.Each frame body 1 includes two support seats 6 and a screw rod 7 on it.Two support seats 6 are fixedly connected at two ends of sliding groove 5 along its length direction, and screw rod 7 is rotatably connected between two support seats 6.Screw rod 7 penetrates sliding block 4 and is threadedly connected with sliding block 4.Especially, the thread directions of two screw rods 7 located on two frame bodies 1 are opposite, and can selectively rotate synchronously.When screw rod 7 rotates, due to opposite thread directions, two support blocks 3 will approach or move away from each other, so as to realize clamping or loosening operation of pipe.

[0031] In order to realize the synchronous rotation of two screw rods 7, one end of one of two screw rods 7 that approaches each other is outwardly protruded to form first insertion block 8, and the other end that approaches each other is inwardly recessed to form first recess 9.First insertion block 8 is detachably connected with first recess 9, and can ensure synchronous rotation in connected state.In the axial direction of screw rod 7, the cross section of first insertion block 8 and first recess 9 is designed as "one" character structure or "ten" character structure, which can not only ensure the stability of connection, but also facilitate synchronous rotation.

[0032] In order to facilitate the manual driving of screw rod 7 by operator, one end of one of two screw rods 7 that moves away from each other is provided with hand wheel 10.Operators can drive screw rod 7 to rotate by rotating hand wheel 10, so as to realize the position adjustment of support block 3, which is simple and convenient to operate.

[0033] One end face of one of two frame bodies 1 that approaches each other is outwardly protruded to form a plurality of second insertion blocks 11, and the other end face that approaches each other is inwardly recessed to form a plurality of second recesses 12.A plurality of second insertion blocks 11 are detachably connected with a plurality of second recesses 12 one by one, and the matching mode of this structure can ensure the stability and reliability of two frame bodies 1 when connected.

[0034] In order to further ensure the stability of the two frame bodies 1 after being connected, a locking clamp 13 is arranged on one side wall of one of the two frame bodies 1, and a locking buckle is arranged in the other frame body 1. The locking buckle is selectively locked with the locking clamp 13, and when the two frame bodies 1 are connected, the locking of the locking buckle with the locking clamp 13 can effectively prevent accidental separation between the frame bodies 1, thereby improving the stability and safety of the whole support during use.

[0035] The end faces of the two supporting blocks 3 close to each other are provided with a circular arc concave surface, the shape of the circular arc concave surface is matched with the outer surface of the pipe, the pipe can be better matched, and the stability and reliability of the bearing are improved. The anti-skid pad 15 is fixedly connected on the circular arc concave surface, the material of the anti-skid pad 15 can be selected from rubber material, the anti-skid pad 15 can increase the friction between the supporting block 3 and the pipe, prevent the pipe from sliding on the supporting block 3, and further improve the stability of the pipe during bearing.

[0036] The use process of the auxiliary support for horizontal directional drilling is as follows:

[0037] S1, assembling the support

[0038] Preparation of components: first, prepare two pipe support monomers that can be assembled with each other.

[0039] Connecting the frame body 1: the two frame bodies 1 are close to each other, the plurality of second insertion blocks 11 on one frame body 1 are inserted into the plurality of second grooves 12 on the other frame body 1 one by one, the first insertion block 8 is inserted into the first groove 9, and preliminary connection is realized. Then, the locking buckle and the locking clamp 13 are locked and matched, and the two frame bodies 1 are further fixed, so that the connection is stable and reliable.

[0040] S2, bearing the pipe

[0041] Moving the support to the designated position: through the walking wheels 2 on the lower surface of the frame body 1, the assembled support is moved to the appropriate position of the horizontal directional drilling construction area, so that the support can conveniently bear the pipe and subsequent operation, the support is arranged at intervals along the length direction of the pipe, the number is adjusted according to the length of the pipe, and the pipe between adjacent supports is not in contact with the ground when bearing the pipe.

[0042] Adjusting the position of the supporting block 3: according to the length of the pipe and the required bearing position, the hand wheel 10 is rotated to drive the screw rod 7 to rotate. Since the threads of the two screw rods 7 are opposite and rotate synchronously, the two supporting blocks 3 will move closer or farther away from each other. The operator observes and adjusts so that the circular arc concave surfaces of the two supporting blocks 3 can be accurately aligned with the two sides of the pipe, thereby providing a suitable supporting space for placing the pipe.

[0043] Placing the drag pipe: slowly place the drag pipe on the arc concave surface of the two support blocks 3, the anti-skid pads 15 on the arc concave surface can increase the friction between the drag pipe and the support blocks, preventing the drag pipe from sliding during placement. After the drag pipe is completely placed on the support blocks 3, adjust the position of the support blocks 3 again to make the support blocks 3 tightly fit the drag pipe, ensuring the stability and safety of the drag pipe during loading.

[0044] S3, moving the drag pipe

[0045] Driving the support frame to move: after the drag pipe is stably loaded, push or pull the support frame to move the drag pipe together with the support frame to the drilling position of the horizontal directional drill by rolling the walking wheels 2. During the movement, the support blocks 3 continuously support the drag pipe to ensure that the drag pipe does not fall or shift during the movement.

[0046] S4, disassembling the support frame

[0047] Loosening the support blocks 3: as the drag pipe is gradually introduced into the borehole under the driving of the drill rod 1 during the drag pipe construction process, the support frame near the borehole needs to be disassembled from the drag pipe in time. First, turn the hand wheel 10 to move the two support blocks 3 away from each other, loosen the clamping of the drag pipe, and then remove the drag pipe from the support blocks 3.

[0048] Separating the frame body 1: unlock the lock and the lock clip 13, then pull out the second insertion block 11 on one frame body 1 from the second groove 12 on the other frame body 1 to separate the two frame bodies 1. The separated frame bodies 1 can be stored or reassembled for use as needed.

[0049] Through the above detailed use process description, the auxiliary support frame for horizontal directional drilling of the present application can efficiently and stably assist the loading and movement of the drag pipe, providing strong support for horizontal directional drilling construction, improving the construction efficiency and safety.

[0050] In use, the two support blocks cooperate with each other to accurately load the drag pipe. The arc concave surface of the support blocks tightly fits the outer surface of the drag pipe, and the anti-skid pads fixedly connected on the concave surface further enhance the friction between the drag pipe and the support blocks. This design enables the drag pipe to be stably placed on the support blocks during loading and movement by relying on the friction between the drag pipe and the support blocks. Since there is no relative sliding between the overall device and the drag pipe, unnecessary friction between the drag pipe and the support blocks or frame during movement is effectively avoided. This is of great significance to protecting the anticorrosive coating of the drag pipe, reducing coating wear caused by friction, prolonging the service life of the drag pipe, and also reducing the risk of corrosion caused by coating damage, ensuring the construction quality and subsequent use performance of the drag pipe.

[0051] The auxiliary support of the utility model has no relative sliding with the drag pipe in the use process, reduces the friction loss, thereby reduces the abrasion degree of each part of the device, effectively reduces the maintenance and repair cost of the auxiliary support of the utility model, and improves the economy and practicality of the device.

[0052] The walking wheels drive the drag pipe to move, and the operator can easily move the drag pipe together with the support to the specified position of the construction area, improving the continuity and efficiency of the construction.

[0053] In the construction process, the stable bearing and non-relative sliding of the drag pipe effectively avoid safety accidents that may be caused by the sliding or falling of the drag pipe. The arc concave surface and non-slip pad design of the support block provide reliable support and non-slip protection for the drag pipe, so that the drag pipe can remain stable and not easily displace or fall off even if it encounters vibration or impact during construction. In addition, the stable connection between the frame bodies and the design of the locking parts ensure the stability of the entire support during use, further improving the safety of the construction and providing a safer and more reliable working environment for the construction personnel.

[0055] The above-described embodiments are only preferred modes of the utility model, and do not limit the scope of the utility model, and various modifications and improvements to the technical solutions of the utility model made by those skilled in the art without departing from the design spirit of the utility model should fall within the protection scope of the utility model claim.
