Description

Technical Field

[0001] The embodiments of this utility model relate to the field of transport vehicle support technology, specifically, to a bracket transport vehicle support mechanism. Background Technology

[0002] A pallet truck is a logistics handling device used for moving goods. It is the simplest, most efficient, and most common loading, unloading, and handling tool among pallet transport vehicles in a handling station.

[0003] In existing technologies, simply using the deployment of outriggers to balance the center of gravity is insufficient to effectively prevent slippage of the outriggers. This leads to slippage of the outriggers when they encounter heavy objects, resulting in instability of the machine. Therefore, we propose a support mechanism for a support vehicle. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a support mechanism for a bracket transport vehicle, which solves the problem in the related technology of being unable to prevent the machine body from slipping and provide stable support.

[0005] According to one aspect, at least one embodiment of the present invention provides a support mechanism for a bracket transport vehicle, including a main frame, a driver's cab at the top of the main frame, an emulsion system at the top of the main frame, an engine assembly at the top of the main frame, a hydraulic system at the top of the main frame, a tracked walking part at the bottom of the main frame, a cantilever beam at the front end of the main frame, a transport mechanism at the side of the cantilever beam, a support rod at the side of the cantilever beam, and an anti-slip mechanism inside the support rod; The anti-slip mechanism includes a mounting groove and a micro motor. The mounting groove is located on the side of the support rod, and its interior is fixedly connected to the top of the micro motor. A threaded rod is fixedly connected to the output end of the micro motor, and a threaded sleeve is threaded onto the circumferential surface of the threaded rod. A first support frame is fixedly connected to the side of the threaded sleeve, and a connecting plate is hinged inside the first support frame. A support shaft is rotatably connected inside the mounting groove, and a rotating plate is fixedly connected to the circumferential surface of the support shaft. A second support frame is fixedly connected to the side of the rotating plate, and its interior is hinged to one end of the connecting plate. A support plate is fixedly connected to the bottom of the support rod, and an extension plate is slidably connected to the bottom of the support plate. A movable rod is fixedly connected to the top of the extension plate. The purpose of this mechanism is to increase the contact area and friction, thereby improving the anti-slip effect.

[0006] For example, in at least one embodiment of the present invention, a support mechanism for a bracket transport vehicle is provided, which further includes: a tension spring fixedly connected inside the support plate, one end of the tension spring away from the inside of the support plate being fixedly connected to the side of the extension plate, and an inclined groove being provided inside the support plate, the purpose of which is to ensure that the extension plate can automatically reset when it is not under force, thereby reducing manual intervention.

[0007] A spring post is slidably connected through the top of the extension plate, and an anti-slip suction cup is fixedly connected to the bottom end of the spring post to improve the anti-slip effect.

[0008] The side of the moving rod is located on the displacement trajectory of the rotating plate, and the inclined surface of the sloping groove is located on the displacement trajectory of the spring column. The purpose is to ensure that the rotation of the rotating plate can push the moving rod, and then the spring column moves and is squeezed by the inclined surface of the sloping groove.

[0009] The number of mounting slots and micro motors is set to two, and they are symmetrical to each other along the vertical central axis of the main frame. The number of expansion plates, inclined slots and spring columns is set to four, and they are symmetrical to each other along the vertical central axis of the main frame. The purpose is to improve the overall protection effect of the main frame through multiple components.

[0010] According to another aspect, at least one embodiment of the present invention also provides a support mechanism for a support vehicle, including a locking mechanism. The locking mechanism includes a hydraulic cylinder, the bottom of which is fixedly connected to the top of a support plate. One end of the hydraulic cylinder is slidably connected to a force rod via a piston, and the other end of the hydraulic cylinder is slidably connected to a hydraulic rod via another piston. A locking block is fixedly connected to the end of the hydraulic rod away from the side of the hydraulic cylinder. A locking groove is provided on the side of the tracked walking part, the purpose of which is to lock the stopped tracked walking part and prevent the main frame from slipping.

[0011] For example, in at least one embodiment of the present invention, a support mechanism for a support vehicle is provided, which further includes: a return spring fixedly connected to the side of the hydraulic cylinder, and the end of the return spring away from the side of the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The purpose is to ensure that the force-bearing rod can automatically reset and reduce manual intervention.

[0012] The locking groove is rotatably connected to a control shaft, and a protective plate is fixedly connected to the circumferential surface of the control shaft. The initial state of the return spring is a relaxed state, which is to prevent debris from entering the locking groove when the main frame moves, thus affecting the locking effect.

[0013] A torsion spring is fixedly connected inside the locking groove. The end of the torsion spring away from the inside of the locking groove is fixedly connected to the circumferential surface of the control shaft. The purpose of this is to ensure that the control shaft can automatically reset and reduce manual intervention.

[0014] The side of the protective plate is located on the displacement trajectory of the locking block. The number of hydraulic cylinders and return springs is set to two, and they are symmetrical to each other along the vertical central axis of the main frame. The purpose is to ensure that the movement of the locking block can push the protective plate into the locking groove.

[0015] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, through the cooperation of components such as the micro motor, extension plate, and anti-slip suction cup of the anti-slip mechanism, when the operator operates the main frame in the cab, it moves to the designated position via the tracked walking part. Before the items need to be moved, the operator controls the support rod to support the main frame through the hydraulic system. Then, the micro motor is started, which causes the rotating plate to push the moving rod, and the extension plate leaves the inside of the support plate and contacts the ground, increasing the contact area between the support plate and the ground. At the same time, the spring column is subjected to the squeezing force, which drives the anti-slip suction cup to make close contact with the ground. This design achieves the effect of protecting the support frame and effectively improves the stability of the machine body.

[0016] 2. In this utility model, through the cooperation between the hydraulic cylinder, locking block, and protective plate of the locking mechanism, the moving rod squeezes the force rod during its movement, causing the force rod to enter the hydraulic cylinder. At this time, the hydraulic rod extends outward under the pressure of the liquid inside the hydraulic cylinder. The movement of the hydraulic rod drives the locking block to move, and the movement of the locking block pushes the protective plate. The protective plate rotates through the control shaft, thereby opening the locking groove and allowing the locking block to enter the locking groove, locking the tracked wheels and thus locking the entire main frame. This design achieves the effect of locking the tracked parts, effectively preventing the tracked wheels from slipping. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-6 As shown, it illustrates a support mechanism for a support vehicle in one embodiment of the present invention, including a main frame 1, a driver's cab 2 at the top of the main frame 1, an emulsion system 3 at the top of the main frame 1, an engine assembly 4 at the top of the main frame 1, a hydraulic system 5 at the top of the main frame 1, a tracked walking part 6 at the bottom of the main frame 1, a cantilever beam 7 at the front end of the main frame 1, a transport mechanism 8 on the side of the cantilever beam 7, a support rod 9 on the side of the cantilever beam 7, and an anti-slip mechanism 10 inside the support rod 9. The anti-slip mechanism 10 includes a mounting groove 101 and a micro motor 102. The mounting groove 101 is located on the side of the support rod 9. The inside of the mounting groove 101 is fixedly connected to the top of the micro motor 102. A threaded rod 103 is fixedly connected to the output end of the micro motor 102. A threaded sleeve 104 is threadedly connected to the circumferential surface of the threaded rod 103. A support frame 105 is fixedly connected to the side of the threaded sleeve 104. A connecting plate 106 is hinged inside the support frame 105. A component is rotatably connected inside the mounting groove 101. A support shaft 107 is provided, and a rotating plate 108 is fixedly connected to the circumferential surface of the support shaft 107. A second support frame 109 is fixedly connected to the side of the rotating plate 108. The interior of the second support frame 109 is hinged to one end of the connecting plate 106. A support plate 1010 is fixedly connected to the bottom end of the support rod 9. An extension plate 1011 is slidably connected to the bottom of the support plate 1010. A moving rod 1012 is fixedly connected to the top of the extension plate 1011. The purpose of this is to increase the contact area, increase the friction, and thus improve the anti-slip effect.

[0027] In some examples, the support plate 1010 is also equipped with a tension spring 1013 fixedly connected inside the support plate 1010. One end of the tension spring 1013 away from the inside of the support plate 1010 is fixedly connected to the side of the extension plate 1011. The support plate 1010 is provided with a slanted groove 1014 inside the support plate, the purpose of which is to ensure that the extension plate 1011 can automatically reset when it is not under force, thereby reducing manual intervention.

[0028] A spring post 1015 is slidably connected through the top of the extension plate 1011, and an anti-slip suction cup 1016 is fixedly connected to the bottom end of the spring post 1015 to improve the anti-slip effect.

[0029] The side of the moving rod 1012 is located on the displacement trajectory of the rotating plate 108, and the inclined surface of the inclined groove 1014 is located on the displacement trajectory of the spring column 1015. The purpose is to ensure that the rotation of the rotating plate 108 can push the moving rod 1012, and then the spring column 1015 moves and is squeezed through the inclined surface of the inclined groove 1014.

[0030] The number of mounting slots 101 and micro motors 102 is set to two, and they are symmetrical to each other along the vertical central axis of the main frame 1. The number of extension plates 1011, inclined slots 1014 and spring columns 1015 is set to four, and they are symmetrical to each other along the vertical central axis of the main frame 1. The purpose is to improve the overall protection effect of the main frame 1 through multiple components.

[0031] For example, such as Figures 1-6As shown, when the operator operates the main frame 1 in the cab 2, it moves to the designated position via the tracked walking unit 6. Before moving items, the operator controls the support rod 9 to support the main frame 1 via the hydraulic system 5. Then, the micro motor 102 is started, and the output end of the micro motor 102 rotates. The rotation of the output end of the micro motor 102 drives the threaded rod 103 to rotate, which in turn drives the threaded sleeve 104 to move. The movement of the threaded sleeve 104 drives the connecting plate 106 to move via the first support frame 105. The movement of the connecting plate 106 pushes the rotating plate 108 via the second support frame 109. The rotating plate 108 is subjected to force through the support shaft 107. The rotating plate 108 pushes the moving rod 1012 during rotation, causing the moving rod 1012 to move the extension plate 1011 inside the support plate 1010. The extension plate 1011 leaves the inside of the support plate 1010 and contacts the ground, increasing the contact area between the support plate 1010 and the ground, thus increasing friction. As the extension plate 1011 moves, it also moves the spring column 1015. When the spring column 1015 moves to the inclined surface of the inclined groove 1014, it is subjected to the squeezing force of the inclined groove 1014, which causes the spring column 1015 to drive the anti-slip suction cup 1016 to make close contact with the ground. Through the increase in area and the anti-slip suction cup 1016, the anti-slip effect of the support rod 9 is improved.

[0032] like Figures 1-6 As shown, it illustrates a support mechanism for a support vehicle in another embodiment of the present invention. It is largely the same as the above-described technical solution, so only the differences are described. It includes a locking mechanism 11, which includes a hydraulic cylinder 111. The bottom of the hydraulic cylinder 111 is fixedly connected to the top of the support plate 1010. One end of the hydraulic cylinder 111 is slidably connected to a force rod 112 via a piston. The other end of the hydraulic cylinder 111 is slidably connected to a hydraulic rod 113 via another piston. A locking block 114 is fixedly connected to the end of the hydraulic rod 113 away from the side of the hydraulic cylinder 111. A locking groove 115 is provided on the side of the tracked walking part 6. The purpose of this is to lock the stopped tracked walking part 6 and prevent the main frame 1 from slipping.

[0033] In some examples, a return spring 118 is fixedly connected to the side of the hydraulic cylinder 111. The end of the return spring 118 away from the side of the hydraulic cylinder 111 is fixedly connected to the circumferential surface of the force rod 112. The purpose is to ensure that the force rod 112 can automatically reset and reduce manual intervention.

[0034] The locking groove 115 is rotatably connected to a control shaft 116. A protective plate 117 is fixedly connected to the circumferential surface of the control shaft 116. The initial state of the return spring 118 is a relaxed state. The purpose is to prevent debris from entering the locking groove 115 when the main frame 1 is moving, which would affect the locking effect.

[0035] A torsion spring 119 is fixedly connected inside the locking groove 115. One end of the torsion spring 119 away from the inside of the locking groove 115 is fixedly connected to the circumferential surface of the control shaft 116. The purpose is to ensure that the control shaft 116 can automatically reset and reduce manual intervention.

[0036] The side of the protective plate 117 is located on the displacement trajectory of the locking block 114. The number of hydraulic cylinders 111 and return springs 118 is set to two, and they are symmetrical to each other along the vertical central axis of the main frame 1. The purpose is to ensure that the movement of the locking block 114 can push the protective plate 117 into the locking groove 115.

[0037] For example, such as Figures 1-6 As shown, during the movement of the moving rod 1012, it compresses the force rod 112, causing the force rod 112 to enter the hydraulic cylinder 111. At this time, the hydraulic rod 113 extends outward under the pressure of the liquid inside the hydraulic cylinder 111. The movement of the hydraulic rod 113 drives the locking block 114 to move. During the movement of the locking block 114, it pushes the protective plate 117. The protective plate 117 rotates through the control shaft 116 under force, thereby opening the locking groove 115 and allowing the locking block 114 to enter the locking groove 115, locking the wheels of the tracked walking part 6, and thus locking the entire main frame 1 to prevent slippage. When the force rod 112 is no longer under force, it is reset by the return spring 118, causing the locking block 114 to leave the locking groove 115. At the same time, the protective plate 117 is reset by the torsion spring 119, closing the locking groove 115 and preventing debris from entering the locking groove 115.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
