Description

Technical Field

[0001] The utility model relates to the technical field of crawler tractors, in particular to a traction structure of a crawler machine. Background Art

[0002] The traction structure of a crawler machine usually refers to the system that drives the movement of the crawler. It can include various designs and configurations. A common traction structure of a crawler machine is a hydraulic drive system that uses hydraulic cylinders or hydraulic motors to drive the rotation of the crawler. This structure is very common in heavy machinery and engineering vehicles. Another is an electric drive system that realizes the forward and backward movement of the crawler through an electric motor and a transmission device.

[0003] The existing patent (publication number: CN218229199U) proposes a crawler traction wheel structure, including a crawler belt, a supporting wheel, a bracket, and a traction wheel. The bracket includes two parallel mounting plates. The mounting plate has a straight section and an inclined section. The supporting wheel is rotatably connected to the straight sections of the two mounting plates, and there is a chute on the inclined section.

[0004] A hydraulic cylinder is arranged on the straight section of the mounting plate. The cylinder body of the hydraulic cylinder is hinged to the mounting plate, and the push rod of the hydraulic cylinder is hinged to the wheel axle of the traction wheel. The wheel axle of the traction wheel is slidably connected in the chute. This utility model has the advantages of improving the comprehensive performance of the crawler walking mechanism, etc.

[0005] However, in actual use, there are still the following deficiencies. For example, the existing crawler machines are not flexible enough when operating in narrow environments. In narrow environments, the operating space of the crawler machine is limited, resulting in the machine being unable to rotate and position freely, thus reducing the operation efficiency. In narrow environments, the crawler machine is more likely to collide with surrounding objects, which may cause equipment damage or personal injury. Therefore, this utility model proposes a traction structure of a crawler machine to solve the above problems. Summary of the Utility Model

[0006] The purpose of this utility model is to solve the deficiencies existing in the prior art and propose a traction structure of a crawler machine.

[0007] To achieve the above purpose, this utility model adopts the following technical scheme: A traction structure of a crawler machine, including a drive wheel, a walking frame is arranged on the drive wheel, a guide wheel is arranged on the walking frame, an adjusting component is arranged on the walking frame, and a crawler is arranged on the drive wheel;

[0008] The adjusting component includes a fixed block and a hydraulic push rod. A rack is slidably connected to the fixed block. A fixing plate is fixed on the rack. The output end of the hydraulic push rod is fixed on the fixing plate. A gear is meshed with the rack. A connecting column is fixed on the gear. The connecting column is rotatably connected to the walking frame. A rotating block is fixed on the connecting column.

[0009] As a preferred embodiment, the fixed block is fixed on the walking frame, and the hydraulic push rod is installed on one side of the walking frame close to the fixed block.

[0010] The beneficial effect of adopting the above further solution is that since the fixed block is fixed on the walking frame, the walking frame can support and fix the fixed block. Since the hydraulic push rod is installed on one side of the walking frame close to the fixed block, the walking frame can provide support and fixation for the fixed block.

[0011] As a preferred embodiment, a chute is formed on the fixed block, a slider is fixed on one side of the rack close to the chute, and the slider is slidably connected in the chute.

[0012] The beneficial effect of adopting the above further solution is that since a chute is formed on the fixed block, a slider is fixed on one side of the rack close to the chute, and the slider is slidably connected in the chute, when the rack moves on the fixed block, the cooperation of the chute and the slider can limit the movement of the rack.

[0013] As a preferred embodiment, a tensioning assembly is arranged on the rotating block. The tensioning assembly includes a protective shell fixed on the rotating block, a transmission motor is installed in the protective shell, and a first rotating rod is fixed to the output end of the transmission motor.

[0014] The beneficial effect of adopting the above further solution is that since the protective shell is fixed on the rotating block, the rotating block can support and fix the protective shell. Since the transmission motor is installed in the protective shell, the protective shell can support and fix the transmission motor and provide protection for it.

[0015] As a preferred embodiment, a second rotating rod is rotatably connected to the first rotating rod, a connecting block is fixed to the second rotating rod, a telescopic block is fixed to the connecting block, and the telescopic block is slidably connected in the rotating block.

[0016] The beneficial effect of adopting the above further solution is that since the output end of the transmission motor is fixed with a first rotating rod and the first rotating rod is rotatably connected with a second rotating rod, after the transmission motor is started, it can drive the first rotating rod and the second rotating rod to rotate. Since the second rotating rod is fixed with a connecting block, the connecting block is fixed with a telescopic block, and the telescopic block is slidably connected in the rotating block, the connecting block can drive the telescopic block to move in the rotating block.

[0017] As a preferred embodiment, a driven wheel is fixed to the telescopic block, and the driven wheel is arranged on the track.

[0018] The beneficial effects of adopting the above further solution are as follows: Since the driven wheel is fixed on the telescopic block and the driven wheel is arranged on the track, the driven wheel can tension the track.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] In the present utility model, the operator starts the hydraulic push rod, and the output end of the hydraulic push rod pushes the fixed plate, so that the fixed plate can drive the rack fixed on the fixed plate to move on the fixed block, so that the rack can drive the gear to rotate on the walking frame, so that the connecting column can drive the rotating block and the driven wheel to rotate, so that the driven wheel rotates to the same horizontal position as the guide wheel, so that the contact length between the track and the road surface is increased, reducing the pressure on the road surface. When the driven wheel is retracted, the contact length between the track and the road surface becomes shorter and the turning radius becomes smaller, thus solving the technical problem that the track machine is not flexible enough when operating in a narrow environment.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1-4 shown, this embodiment provides a technical solution: a traction structure for a crawler machine, including a drive wheel 1, a walking frame 3 is arranged on the drive wheel 1, a guide wheel 2 is arranged on the walking frame 3, an adjustment assembly 4 is arranged on the walking frame 3, and a crawler 6 is arranged on the drive wheel 1;

[0032] As Figures 1-3 shown, the adjustment assembly 4 includes a fixed block 41 and a hydraulic push rod 46. A rack 43 is slidably connected to the fixed block 41. A fixing plate 45 is fixed on the rack 43. The output end of the hydraulic push rod 46 is fixed on the fixing plate 45. A gear 47 is engaged with the rack 43. A connecting column 48 is fixed on the gear 47. The connecting column 48 is rotatably connected to the walking frame 3. A rotating block 49 is fixed on the connecting column 48. After the operator starts the hydraulic push rod 46, its output end pushes the fixing plate 45, causing the rack 43 fixed on the plate to move along the fixed block 41. This action drives the gear 47 to rotate on the walking frame 3, and then the connecting column 48 drives the rotating block 49 and the driven wheel 57 to turn until they are flush with the guide wheel 2. This process increases the contact length between the crawler 6 and the ground, reduces the pressure on the ground, improves the stability of the machine during operation and reduces damage to the road surface. After retracting the driven wheel 57, the turning radius decreases accordingly, greatly improving the operation flexibility of the crawler-type machine in a narrow environment, thus solving the technical problem that the crawler 6 machine is not flexible enough when operating in a narrow environment.

[0033] In the above solution, there is also a problem that the crawler machine cannot meet the requirement of tensioning the crawler 6 during operation, as Figures 1-3As shown in the figure: The fixed block 41 is fixed on the walking frame 3, and the hydraulic push rod 46 is installed on one side of the walking frame 3 close to the fixed block 41. Since the fixed block 41 is fixed on the walking frame 3, the walking frame 3 can support and fix the fixed block 41. Since the hydraulic push rod 46 is installed on one side of the walking frame 3 close to the fixed block 41, the walking frame 3 can provide support and fixation for the fixed block 41. A chute 42 is provided on the fixed block 41, and a slider 44 is fixed on one side of the rack 43 close to the chute 42. The slider 44 is slidably connected in the chute 42. Since the chute 42 is provided on the fixed block 41, the slider 44 is fixed on one side of the rack 43 close to the chute 42, and the slider 44 is slidably connected in the chute 42, when the rack 43 moves on the fixed block 41, through the cooperation of the chute 42 and the slider 44, it can limit the movement of the rack 43;

[0034] As Figures 1-2 and Figure 4 shown in the figure, a tensioning assembly 5 is provided on the rotating block 49. The tensioning assembly 5 includes a protective shell 51. The protective shell 51 is fixed on the rotating block 49. A transmission motor 52 is installed in the protective shell 51. A first rotating rod 53 is fixed to the output end of the transmission motor 52. Since the protective shell 51 is fixed on the rotating block 49, the rotating block 49 can support and fix the protective shell 51. Since the transmission motor 52 is installed in the protective shell 51, the protective shell 51 can support, fix and protect the transmission motor 52. A second rotating rod 54 is rotatably connected to the first rotating rod 53. A connecting block 55 is fixed to the second rotating rod 54. A telescopic block 56 is fixed to the connecting block 55. The telescopic block 56 is slidably connected in the rotating block 49. Since the output end of the transmission motor 52 is fixed to the first rotating rod 53 and the first rotating rod 53 is rotatably connected to the second rotating rod 54, after the transmission motor 52 is started, it can drive the first rotating rod 53 and the second rotating rod 54 to rotate. Since the connecting block 55 is fixed to the second rotating rod 54 and the telescopic block 56 is fixed to the connecting block 55, and the telescopic block 56 is slidably connected in the rotating block 49, the connecting block 5 can drive the telescopic block 56 to move in the rotating block 49. A driven wheel 57 is fixed to the telescopic block 56. The driven wheel 57 is arranged on the crawler belt 6. Since the driven wheel 57 is fixed to the telescopic block 56 and the driven wheel 57 is arranged on the crawler belt 6, the driven wheel 57 can tension the crawler belt 6.

[0035] Working principle:

[0036] As Figures 1-4As shown, first, after the operator starts the hydraulic push rod 46, its output end pushes the fixed plate 45, causing the rack 43 fixed on the plate to move along the fixed block 41. This action drives the gear 47 to rotate on the traveling frame 3, and then the connecting column 48 drives the rotating block 49 and the driven wheel 57 to turn until they are flush with the guide wheel 2. This process increases the contact length between the crawler 6 and the ground, reduces the pressure on the ground, improves the stability of the machine during operation, and reduces damage to the road surface. After the driven wheel 57 is retracted, the turning radius decreases, greatly improving the operation flexibility of the crawler-type machine in a narrow environment. When the crawler 6 becomes loose, the operator starts the transmission motor 52. The output end of the transmission motor 52 drives the first rotating rod 53 and the second rotating rod 54 to rotate, causing the second rotating rod 54 to drive the connecting block 55 and the telescopic block 56 to move within the rotating block 49. When the telescopic block 56 rises, it can tension the crawler 6 to prevent the loosening of the crawler 6 from affecting the normal operation of the crawler 6 machine.

[0037] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
