Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wiring harness plug-in unit for a paver. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. The paving work is completed by the cooperation of various systems, mainly including the travel system, hydraulic system, material distribution system, etc. During the operation of the paver, in order to maintain the paving accuracy, the lower and middle surface layers are generally paved with wire ropes to guide the elevation control. When using wire ropes to guide the elevation control, a wiring structure is required to support and fix the wire rope. In order to maintain the stability of the wire rope, the wiring structure connected to the wire harness needs to be firmly connected to the ground to avoid shaking and offset of the wiring structure.

[0003] Most of the existing wiring structures are fastened to the ground by bolts or pluggable limit pins. During the construction of the paver, there is uncertainty in the construction environment. If the construction environment is a muddy ground, the surface soil of the muddy ground is relatively soft after rainy weather. The wiring structure adopts the original bolt and limit pin installation method, and the stability will be destroyed, which in turn affects the stability of the wire rope and the working efficiency of the paver. Utility Model Content

[0004] In response to the above problems, the present application provides a wiring harness plug-in for a paving machine.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a wiring harness plug-in for a paving machine, comprising a support seat and a positioning rod plugged into the inner side of the top end of the support seat, the bottom end of the support seat is fixedly connected to the base plate, and an embedded rod that can be raised and lowered is arranged on the inner side of the support seat, and the embedded rod can be lowered and extended from under the base plate.

[0006] The outer surface of the support seat is provided with a traction ring that can be raised and lowered, and the side surface of the traction ring is fixedly connected with linkage seats at both ends along its radial position. When the embedded rod descends to a certain extent, the traction ring and the linkage seat descend synchronously, and the linkage seat is connected to a first movable arm that can be descended and extended to the bottom of the base plate through a rotating shaft, and the bottom end of the first movable arm is connected to a rotatable second movable arm through a rotating shaft, and the end of the second movable arm away from the first movable arm is connected to the base plate through a rotating shaft.

[0007] Furthermore, the bottom end of the embedded rod shrinks inwardly to form a tapered portion, and the shrinking end of the tapered portion has a sawtooth structure.

[0008] Furthermore, a pair of follower plates and an extension plate are fixedly connected to the outer surface of the embedded rod and close to the upper side, and the extension plate is located directly above the linkage seat.

[0009] Furthermore, the surface of the support seat is provided with accommodating channel 1 and accommodating channel 2 which can respectively accommodate the ascending and descending sliding of the follower plate and the extension plate. The linkage seat is opposite to the inner side of the accommodating channel 2. When the extension plate is located on the inner side of the accommodating channel 2 and slides down to a certain extent, it contacts the linkage seat.

[0010] Furthermore, a guide channel for accommodating the passage of the first movable arm is provided on the surface of the bottom plate, the guide channel is connected to the second accommodating channel, and a receiving groove for accommodating the second movable arm to be rotated out and in is provided on the lower surface of the bottom plate.

[0011] Furthermore, a guide rod is fixedly connected to the inner cavity of the support seat, and the guide rod extends to the inner cavity at the top end of the embedded rod. When the embedded rod moves up and down, the embedded rod slides and contacts with the side surface of the guide rod.

[0013] The utility model can be installed on a muddy ground with a relatively soft surface soil. The embedding rod can be lowered and extended from the bottom of the base plate until it is embedded in the muddy ground, thereby improving the stability of the base plate and preventing the base plate and the support seat from shaking or tipping over. After the embedding rod is lowered to a certain extent, the traction ring and the linkage seat can be driven to descend synchronously, and the first movable arm pushes the second movable arm to rotate out, forming a triangular support structure under the base plate and embedding in the muddy ground. The embedding strength of the entire base plate for the muddy ground with a relatively soft surface soil is improved, and the stability of the base plate and the support seat under the impact of external forces is further improved, thereby improving the protective effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1 , Figure 2 The wiring harness plug-in for a paving machine shown in the figure includes a support seat 1 and a positioning rod 7 inserted into the inner side of the top of the support seat 1. The bottom end of the support seat 1 is fixedly connected to the base plate 2, and the inner side of the support seat 1 is provided with an embedding rod 3 that can move up and down. When the wiring harness plug-in needs to be installed on a muddy ground with a relatively soft surface soil, the embedding rod 3 can be lowered and extended from the bottom of the base plate 2 until it is embedded in the muddy ground, thereby improving the stability of the base plate 2 and avoiding shaking and tipping of the base plate 2 and the support seat 1.

[0023] The outer surface of the support seat 1 is sleeved with a traction ring 4 that can be raised and lowered, and the side surface of the traction ring 4 is fixedly connected with a linkage seat 41 at both ends of its radial position. After the embedded rod 3 is lowered to a certain extent, the traction ring 4 and the linkage seat 41 are lowered synchronously, and the linkage seat 41 is connected to a first movable arm 5 that can be lowered and extended to the bottom of the base plate 2 through a rotating shaft, and the bottom end of the first movable arm 5 is connected to a rotatable second movable arm 6 through a rotating shaft, and the end of the second movable arm 6 away from the first movable arm 5 is connected to the base plate 2 through a rotating shaft. Therefore, as the first movable arm 5 descends, the second movable arm 6 can be rotated and pushed out, forming a triangular support structure below the base plate 2 and embedded in the muddy ground.

[0024] Through this support structure, the embedding strength of the entire base plate 2 in the muddy ground with relatively soft surface soil can be improved, the stability of the base plate 2 and the support seat 1 under external force impact is further improved, the protection effect of the support seat 1 and the positioning rod 7 is improved, and the applicability and stability of the wiring harness plug-in during installation and operation are enhanced.

[0025] like Figure 3 , Figure 4 As shown, the bottom end of the embedding rod 3 shrinks inward to form a tapered portion 31, and the conical portion 31 has a sawtooth structure. When the embedding rod 3 is lowered and embedded in the ground, the setting of the tapered portion 31 can reduce the resistance during the embedding process and improve the smoothness of the descending movement.

[0026] like Figure 1 , Figure 3 As shown, a pair of follower plates 32 and an extension plate 33 are fixedly connected to the outer surface of the embedded rod 3 and close to the upper side, and the extension plate 33 is located directly above the linkage seat 41. The setting of the follower plate 32 can be convenient for the staff to press to achieve the purpose of driving the embedded rod 3 to fall.

[0027] like Figure 1 , Figure 3 As shown, the surface of the support seat 1 is provided with a receiving channel 11 and a receiving channel 2 12 which can respectively accommodate the ascending and descending sliding of the follower plate 32 and the extension plate 33, and the linkage seat 41 is directly opposite to the inner side of the receiving channel 2 12. When the extension plate 33 is located inside the receiving channel 2 12 and slides down to a certain extent, it contacts the linkage seat 41. As the extension plate 33 continues to descend, the linkage seat 41 and the traction ring 4 are driven down under the pressure until the first moving arm 5 pushes the second moving arm 6 to rotate out.

[0028] like Figure 2 , Figure 4 As shown, the surface of the bottom plate 2 is provided with a guide channel 21 for accommodating the first movable arm 5 to pass through, the guide channel 21 is connected with the accommodating channel 2 12, and the lower surface of the bottom plate 2 is provided with a receiving groove 22 for accommodating the second movable arm 6 to be rotated out and in. In a natural state, the second movable arm 6 extends into the inside of the receiving groove 22 to keep the bottom of the bottom plate 2 flat, and further maintain that when the bottom plate 2 is installed on the muddy ground, the first movable arm 5 can push the second movable arm 6 to rotate out, forming a triangular support structure below the bottom plate 2, embedded in the mud.

[0029] like Figure 5 As shown, the inner cavity of the support seat 1 is fixedly connected with a guide rod 13, and the guide rod 13 extends to the inner cavity at the top end of the embedded rod 3. When the embedded rod 3 moves up and down, the embedded rod 3 slides in contact with the side surface of the guide rod 13. The sliding connection between the guide rod 13 and the embedded rod 3 can maintain the linearity of the embedded rod 3 during movement, and avoid shaking and deviation of the embedded rod 3.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
