Description

Technical Field

[0001] This utility model relates to the field of track beam technology, and in particular to a pivot-type track beam for engineering vehicles. Background Technology

[0002] Track beams are mainly used in the main frame structure of engineering vehicles, serving as the carrier for load-bearing, power systems, and structures. They are the most important load-bearing structure in the entire vehicle. Currently, track beams bear relatively light weights, cannot withstand large pressures during use, are not very precise in installation, and have poor stability.

[0003] To address the aforementioned issues, existing technology CN208325440U provides a pivot-type track beam for engineering vehicles, comprising a track beam body. One end of the track beam body has a mounting plate extending beyond one side of the track beam body, with a drive wheel mounting position fixed at the extended end. The other end of the track beam body has a guide wheel mounting position, which is a fork-shaped structure. A pivot seat is connected to the rear of the guide wheel mounting position, and an undercarriage pivot mounting position is located on the upper part of the pivot seat. A tow wheel mounting seat is connected to the middle of the track beam body, and tow wheel mounting positions are located on both the rear of the pivot seat and the tow wheel mounting seat. An undercarriage connecting rod mounting position is also fixed to the track beam body, and a support roller mounting position is located at the bottom of the track beam body. This invention integrates one tow wheel mounting position and one undercarriage pivot mounting position onto the pivot seat, resulting in a high degree of integration for the entire track beam. Because the force is distributed to various parts of the track beam, it can withstand greater pressure.

[0004] However, in the aforementioned prior art, since there are no load-bearing support points on the outer side of the track beam body, it is prone to deformation and damage when subjected to pressure. Utility Model Content

[0005] The purpose of this utility model is to provide a pivot-type track beam for engineering vehicles, which solves the technical problem in the prior art that the track beam body is prone to deformation and damage when subjected to pressure because there are no force support points on the outside.

[0006] To achieve the above objectives, this utility model employs a pivot-type track beam for engineering vehicles, comprising a track beam body and several reinforcing components. Each reinforcing component includes a reinforcing plate, a knob, a drive assembly, two transmission components, two connecting arms, two sliding structures, and two locking rods. The track beam body is provided with several mounting holes. The knob, the drive assembly, the two sliding structures, and the two locking rods are respectively disposed on the reinforcing plate. The drive assembly is fixedly connected to the knob and located at one end of the knob. The two transmission components are slidably connected to the drive assembly and symmetrically disposed at one end of the drive assembly. One end of each connecting arm is rotatably connected to the corresponding transmission component and located at one end of the corresponding transmission component. The other end of each connecting arm is rotatably connected to the corresponding sliding structure and located at one end of the corresponding sliding structure. Each locking rod is fixedly connected to the corresponding sliding structure and located at the other end of the corresponding sliding structure. Each locking rod engages with a corresponding mounting hole.

[0007] The drive assembly includes a drive rod and a bidirectional screw. The drive rod is fixedly connected to the knob and located at one end of the knob. The bidirectional screw is fixedly connected to the drive rod and located at one end of the drive rod.

[0008] Each of the transmission components includes a sliding mechanism and a connecting frame. The sliding mechanism is slidably connected to the bidirectional screw and is located at one end of the bidirectional screw. The connecting frame is fixedly connected to the sliding mechanism and is located at one end of the sliding mechanism.

[0009] Each of the connecting arms includes an arm body and a rotating shaft. One end of the arm body is rotatably connected to the connecting frame and is located at one end of the connecting frame. One end of the rotating shaft is rotatably connected to the arm body and is located in the middle of the arm body. The other end of the rotating shaft is fixedly connected to the reinforcing plate and is located inside the reinforcing plate.

[0010] Each of the sliding structures includes a slide rod and a slide frame. One end of the slide frame is slidably connected to the slide rod and located at one end of the slide rod. The other end of the slide frame is rotatably connected to the arm body and located at one end of the arm body.

[0011] This utility model discloses a pivot-type track beam for engineering vehicles. A knob, a drive assembly, two sliding structures, and two locking rods are respectively disposed on a reinforcing plate. The drive assembly is fixedly connected to the knob and located at one end of the knob. Two transmission components are slidably connected to the drive assembly and symmetrically disposed at one end of the drive assembly. One end of each connecting arm is rotatably connected to a corresponding transmission component and located at one end of the corresponding transmission component. The other end of each connecting arm is rotatably connected to a corresponding sliding structure and located at one end of the corresponding sliding structure. Each locking rod is fixedly connected to a corresponding sliding structure and located at the corresponding sliding structure. At the other end, each locking rod engages with a corresponding mounting hole. The reinforcing plate is placed at the two corresponding mounting holes. Then, the knob is rotated, which drives the drive assembly to rotate. The drive assembly drives the two transmission components to move relative to each other. The two transmission components drive the two connecting arms to move relative to each other within the reinforcing plate. The two connecting arms drive the two locking rods to move relative to each other through the two sliding structures, so that the two locking rods are inserted into the two mounting holes, thereby fixing the reinforcing plate to the outside of the track beam body. This method can effectively solve the problem that the track beam body is prone to deformation and damage when subjected to pressure because there are no force support points on the outside.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-3 ,in Figure 1 This is a structural schematic diagram of a pivot-type track beam for an engineering vehicle according to this utility model. Figure 2 This is a front view of a pivot-type track beam for engineering vehicles according to this utility model. Figure 3 This is the utility model Figure 2 A structural cross-sectional view of line AA.

[0019] This utility model provides a pivot-type track beam for engineering vehicles, including a track beam body 101, a reinforcing plate 102, a knob 103, a locking rod 104, a drive rod 105, a two-way screw 106, a sliding mechanism 107, a connecting frame 108, a boom 109, a rotating shaft 110, a sliding rod 111, and a sliding frame 112. The aforementioned solution solves the problem that the track beam body 101 is prone to deformation and damage when subjected to pressure because there are no force support points on its outer side.

[0020] In this specific embodiment, the track beam body 101 is provided with a plurality of mounting holes 113. The knob 103, the drive assembly, the two sliding structures, and the two locking rods 104 are respectively disposed on the reinforcing plate 102. The drive assembly is fixedly connected to the knob 103 and is located at one end of the knob 103. The two transmission components are slidably connected to the drive assembly and are symmetrically disposed at one end of the drive assembly. One end of each connecting arm is rotatably connected to the corresponding transmission component and is located at one end of the corresponding transmission component. The other end of each connecting arm is rotatably connected to the corresponding sliding structure and is located at one end of the corresponding sliding structure. Each locking rod 104 is fixedly connected to the corresponding sliding structure and is located at the other end of the corresponding sliding structure. The rod 104 engages with the corresponding mounting hole 113, placing the reinforcing plate 102 at the two corresponding mounting holes 113. Then, the knob 103 is rotated, causing the drive assembly to rotate. The drive assembly drives the two transmission components to move relative to each other, which in turn drives the two connecting arms to move relative to each other within the reinforcing plate 102. The two connecting arms, through the two sliding structures, drive the two locking rods 104 to move relative to each other, inserting the two locking rods 104 into the two mounting holes 113. This fixes the reinforcing plate 102 to the outside of the track beam body 101. Since the knob 103 is embedded in the reinforcing plate 102, it will not easily rotate, thus supporting the track beam body 101 and preventing it from deforming under pressure.

[0021] The drive assembly includes a drive rod 105 and a bidirectional screw 106. The drive rod 105 is fixedly connected to the knob 103 and is located at one end of the knob 103. The bidirectional screw 106 is fixedly connected to the drive rod 105 and is located at one end of the drive rod 105. The knob 103 drives the bidirectional screw 106 to rotate through the drive rod 105.

[0022] Secondly, each of the transmission components includes a slide 107 and a connecting frame 108. The slide 107 is slidably connected to the bidirectional screw 106 and is located at one end of the bidirectional screw 106. The connecting frame 108 is fixedly connected to the slide 107 and is located at one end of the slide 107. The bidirectional screw 106 drives the slide 107 to move, and the slide 107 drives the connecting frame 108 to move.

[0023] Meanwhile, each of the connecting arms includes an arm body 109 and a rotating shaft 110. One end of the arm body 109 is rotatably connected to the connecting frame 108 and is located at one end of the connecting frame 108. One end of the rotating shaft 110 is rotatably connected to the arm body 109 and is located in the middle of the arm body 109. The other end of the rotating shaft 110 is fixedly connected to the reinforcing plate 102 and is located inside the reinforcing plate 102. The connecting frame 108 drives one end of the arm body 109 to move. At this time, the arm body 109 rotates with the rotating shaft 110 as the fulcrum.

[0024] In addition, each of the sliding structures includes a slide rod 111 and a slide carrier 112. One end of the slide carrier 112 is slidably connected to the slide rod 111 and is located at one end of the slide rod 111. The other end of the slide carrier 112 is rotatably connected to the arm body 109 and is located at one end of the arm body 109. The other end of the arm body 109 drives the slide carrier 112 to move on the slide rod 111.

[0025] In the specific use of the pivot-type track beam for engineering vehicles according to this embodiment, the reinforcing plate 102 is placed at the corresponding two mounting holes 113, and then the knob 103 is rotated. The knob 103 drives the bidirectional screw 106 to rotate through the drive rod 105. The bidirectional screw 106 drives the two sliding blocks 107 to move relative to each other. The two sliding blocks 107 drive one end of the two arms 109 to move relative to each other through the two connecting frames 108. At this time, the two arms 109 rotate relative to each other with the two rotating shafts 110 as fulcrums. The other end of the two arms 109 drives the two slide frames 112 to move relative to each other on the two slide rods 111. The two slide frames 112 drive the two locking rods 104 to be inserted into the two corresponding mounting holes 113, thereby fixing the reinforcing plate 102 to the outside of the track beam body 101, thereby supporting the track beam body 101 and preventing it from deforming under pressure.

[0026] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
