[0001] The invention belongs to the technical field of traction devices, in particular to a traction device for a construction loader. Background Art

[0002] In addition to shoveling loose materials such as soil, sand, lime, coal, etc., loaders can also perform light shoveling and excavation operations on ore, hard soil, etc. By replacing different auxiliary working devices on the working part of the loader, it can also perform bulldozing, lifting and loading and unloading operations of other materials such as wood. It is widely used in working environments such as roads, railways, construction, hydropower, ports, and mines. When a loader breaks down, a traction device is usually required to tow it.

[0003] A loader traction device with a prior publication number of CN213799126U is provided with a buffer mechanism. When the tractor brakes, the loader body continues to move under the action of inertia, while the piston plate is fixed. The spring and the telescopic rod are compressed to provide corresponding buffering to the piston plate. The air in the air cavity enters the buffer airbag through the air pipe to provide further buffering, thereby preventing the loader from continuing to move and pushing the tractor to move, thereby ensuring the safety of the tractor.

[0004] However, in the process of implementing the above technical solution, it is found that the above technology has at least the following technical problems:

[0005] First, the buffer mechanism for ensuring the safety of the tractor under the action of inertia is arranged inside the loader. As a structural accessory of the loader, it changes the existing structure of the loader and increases the production process of the loader;

[0006] Second, when the tractor is connected to the loader, the buffer mechanism may not be able to connect with the gear ring on the tractor due to the large height difference between the two. Summary of the invention

[0007] In order to overcome the existing deficiencies, an embodiment of the present application provides a traction device for a construction loader, which connects the traction bars on both sides by using a connecting piece, and hinges a traction head at one end of the traction bar. When the traction hook fixed at one end of the traction head is hooked with the first traction ring and the second traction ring, tractors of different heights can be connected to the construction loader, thereby solving the problem that when the tractor is connected to the loader, the buffer mechanism cannot be connected to the gear ring on the tractor due to the large height difference between the two.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A traction device for a construction loader includes a two-part structure, namely: a traction mechanism and a buffer mechanism, the traction mechanism includes a plurality of connecting members, both sides of the connecting members are provided with traction bars, one side of the traction bar is provided with a traction head, one end of the traction head is fixedly connected with a traction hook;

[0010] The buffer mechanism comprises a control disk, the centers of both sides of the control disk are fixedly connected with adapter columns, one end of the adapter column is fixedly connected with a baffle, and a spring is arranged on one side of the baffle.

[0011] In a possible implementation, the connecting member includes two plates, which are respectively located on both sides of the traction bar, and a seat plate is fixedly connected to one side of the two plates close to the center of the cross-section of the control disk, and two pull arms are fixedly connected to the surface of the seat plate, and the internal pins at one end of the two pull arms are connected to the same pull rod.

[0012] In a possible implementation, a second shaft is rotatably connected to one end of the traction bar, a first shaft is rotatably connected to the other end of the traction bar, the second shaft is pin-connected to the inside of the traction head, and the first shaft is pin-connected to the inside of one end of the two plates.

[0013] In a possible implementation, a second shaft is rotatably connected to one end of the traction bar, a first shaft is rotatably connected to the other end of the traction bar, the second shaft is pin-connected to the inside of the traction head, and the first shaft is pin-connected to the inside of one end of the two plates.

[0014] In a possible implementation, a plurality of strip grooves are provided inside the control panel, and a plurality of the pull rods are respectively slidably connected inside the strip grooves.

[0015] In a possible implementation, a plurality of cylindrical grooves are formed inside the spring, and one end of the pull rod is movably connected inside the cylindrical groove.

[0016] In a possible implementation, a support sleeve rod is fixedly connected to the center of one side of the baffle, and the spring is movably sleeved on the outside of the support sleeve rod.

[0017] In a possible implementation, the spring is movably connected between a plurality of traction strips, and the surface of the seat is movably connected to the outer wall of the control disk.

[0018] In a possible implementation, one end of the support sleeve is movably connected to the interior of the traction head, one end of the spring is contact-connected to one side of the traction head, and the other end of the spring is contact-connected to one side of the baffle.

[0022] Second, in this solution, when the traction mechanism is braked and the construction loader moves forward due to inertia, the inertial force is used to push the two traction heads closer to each other, so that one end of the traction bar rotates around the second shaft rod, and the other end of the traction bar moves to the side away from the control disk by pushing the plate, so that the rigidity of the traction mechanism as a whole can be reduced, and at the same time, the spring squeezed by the two traction heads is used for buffering, so that the service life of the overall structure of the traction mechanism can be guaranteed;

[0023] Third, in this scheme, the construction loader applies pressure to the traction mechanism due to the inertia force by braking the tractor, so that the two traction heads are close to each other to squeeze the spring, and the spring can be used for buffering to ensure the safety of traction work;

[0033] The embodiment of the present application provides a traction device for a construction loader. When the traction machine is braked and the construction loader moves forward due to inertia, the inertia force is used to push the two traction heads closer to each other, so that one end of the traction bar rotates around the second shaft rod, and the other end of the traction bar moves to the side away from the control disk by pushing the plate, thereby reducing the overall rigidity of the traction mechanism and cooperating with the spring squeezed by the two traction heads for buffering.

[0034] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0035] Embodiment 1:

[0036] This embodiment introduces a specific structure of a traction device for a construction loader. Figure 1-Figure 7 As shown, it comprises: a traction mechanism 3 and a buffer mechanism 5, the traction mechanism 3 comprises a plurality of connecting members 31, both sides of the connecting members 31 are provided with traction bars 32, one side of the traction bar 32 is provided with a traction head 33, one end of the traction head 33 is fixedly connected with a traction hook 2;

[0037] A first traction ring 1 is hooked inside one of the traction hooks 2, and a second traction ring 4 is hooked inside the other traction hook 2;

[0038] One end of the first traction ring 1 is fixedly connected to a construction loader, and one end of the second traction ring 4 is fixedly connected to a traction machine. During the movement of the traction machine, the second traction ring 4 and a traction hook 2 are used to pull the traction mechanism 3 so that the other traction hook 2 can tow the construction loader through the first traction ring 1;

[0039] Secondly, one traction hook 2 is hooked on the outside of the first traction ring 1, and the other traction hook 2 is hooked on the outside of the second traction ring 4, so that when the traction mechanism 3 is used for traction work, it is not affected by the height difference between the tractor and the construction loader;

[0040] In some examples, the connecting member 31 includes two plates 311, the two plates 311 are respectively located on both sides of the traction bar 32, and a seat 313 is fixedly connected to one side of the two plates 311 close to the center of the cross section of the control disk 54, and two pull arms 314 are fixedly connected to the surface of the seat 313, and the inner pins at one end of the two pull arms 314 are connected to the same pull rod 315;

[0041] The two plates 311 connect the left and right traction bars 32 together, and when the two traction bars 32 are squeezed and moved closer to each other, they can rotate around the first shaft 312, providing a certain movable gap;

[0042] In some examples, in order to prevent the traction bar 32 from rotating around the first shaft 312 and causing the two traction heads 33 to be too close to each other, a plurality of strip grooves 55 are provided inside the control disk 54, and a plurality of pull rods 315 are respectively connected in a sliding manner inside the strip grooves 55. When the two traction bars 32 are pressed and moved close to each other, causing the connecting member 31 to move toward a side away from the center of the cross section of the control disk 54, the pull rod 315 slides from one end of the strip groove 55 close to the center of the cross section of the control disk 54 to the other end away from the center of the cross section of the control disk 54, so that the distance of the connecting member 31 away from the control disk 54 can be controlled;

[0043] In some examples, the second shaft 35 is rotatably connected to one end of the traction bar 32, the first shaft 312 is rotatably connected to the other end of the traction bar 32, the second shaft 35 is pin-connected to the inside of the traction head 33, and the first shaft 312 is pin-connected to the inside of one end of the two plates 311;

[0044] When the two traction bars 32 are squeezed and moved closer to each other, one end of the traction bar 32 rotates around the first shaft 312, and the other end of the traction bar 32 rotates around the second shaft 35;

[0045] In some examples, a plurality of receiving grooves 34 are provided on the outer side of one side of the traction head 33, and the plurality of receiving grooves 34 are equally spaced around the outer side of the traction head 33, and one end of the traction bar 32 is rotatably connected to the inside of the receiving groove 34;

[0046] One end of the traction bar 32 is received in the receiving groove 34 , and when one end of the traction bar 32 rotates around the second shaft 35 and the other end of the traction bar 32 approaches the control plate 54 , the traction mechanism 3 can be free of protrusions around it.

[0047] By adopting the above technical solution:

[0048] The above design uses a connecting piece 31 to connect the traction bars 32 on both sides, and one end of the traction bar 32 is hinged with a traction head 33. When the traction hook 2 fixed at one end of the traction head 33 is hooked with the first traction ring 1 and the second traction ring 4, the tractor at different heights can be connected to the construction loader. The traction head 33 is pulled by the two traction bars 32 on the connecting piece 31, so that the tractor can tow the construction loader. When the tractor is braked and the construction loader moves forward due to inertia, one end of the traction bar 32 rotates around the second shaft rod 35, and the other end of the traction bar 32 is connected to the second shaft rod 35. By pushing the plate 311 to move toward the side away from the control disk 54 and reducing the distance between the two traction heads 33, the overall rigidity of the traction mechanism 3 can be reduced. In the process of the plate 311 moving away from the control disk 54, the pull rod 315 pinned to one end of the pull arm 314 is slidably connected to the inside of the strip groove 55. When the pull rod 315 slides from the end of the strip groove 55 close to the center of the cross section of the control disk 54 to the end away from the center of the cross section of the control disk 54, the distance of the plate 311 away from the control disk 54 can be controlled to prevent the towed construction loader from colliding with the tractor.

[0049] Embodiment 2:

[0050] Based on Example 1, this example introduces the specific structure of a buffer mechanism 5, wherein the buffer mechanism 5 includes a control plate 54, and the centers of both sides of the control plate 54 are fixedly connected with adapter columns 57, and one end of the adapter column 57 is fixedly connected with a baffle plate 51, and a spring 52 is provided on one side of the baffle plate 51;

[0051] The spring 52 is movably connected between the plurality of traction bars 32, and the surface of the seat plate 313 is movably connected to the outer wall of the control plate 54. When the two traction heads 33 approach each other, the spring 52 supported between the traction heads 33 and the baffle plate 51 is compressed, and the baffle plate 51 isolates the control plate 54 from the spring 52, and does not affect the sliding of the pull rod 315 in the strip groove 55.

[0052] In some examples, a plurality of cylindrical grooves 56 are formed inside the spring 52, and one end of the pull rod 315 is movably connected inside the cylindrical groove 56;

[0053] The pull rod 315 is passed through the cylindrical groove 56 and pinned to the inside of the two pull arms 314, so that the pull rod 315 can be slidably connected to the inside of the strip groove 55 without being interfered by the two baffles 51;

[0054] In some examples, in order to control the direction in which the spring 52 contracts between the plurality of traction bars 32, a support sleeve rod 53 is fixedly connected to the center of one side of the baffle 51, and the spring 52 is movably sleeved on the outside of the support sleeve rod 53;

[0055] In some examples, one end of the support sleeve rod 53 is movably connected to the inside of the traction head 33, one end of the spring 52 is contact-connected to one side of the traction head 33, and the other end of the spring 52 is contact-connected to one side of the baffle 51;

[0056] When the two traction heads 33 approach each other to press the spring 52 , the support sleeve rod 53 is slidably connected inside the traction heads 33 .

[0057] In the specific use process:

[0058] S1, the tractor brakes so that the construction loader applies pressure to the traction mechanism 3 due to inertia, so that the two traction heads 33 approach each other;

[0059] S2, the traction bar 32 connected between the traction head 33 and the connecting member 31 pushes the connecting member 31 away from the control plate 54, and compresses the spring 52 supported between the baffle plate 51 and the traction head 33 to perform buffering work;

[0060] S3. When the two traction heads 33 approach each other, the support sleeve rod 53 slides into the interior of the traction head 33.

[0061] By adopting the above technical solution:

[0062] The above design causes the construction loader to apply pressure to the traction mechanism 3 due to inertia when the tractor brakes, so that the two traction heads 33 are close to each other to squeeze the spring 52, and the spring 52 is used for buffering. At the same time, the pull rod 315 slides from one end of the strip groove 55 to the other end to control the maximum distance of the plate 311 away from the control disk 54. The plate 311 can be supported between the plate 311 and the traction head 33, so as to control the distance between the two traction heads 33, and effectively prevent the spring 52 from being over-compressed.

[0063] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the invention.
