Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The examples in the embodiments are intended to be used for explaining the present application and are not to be construed as limiting the present application.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself may be included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Examples: the present embodiment provides a traction mounting device, as shown in fig. 1 and 2, which is used to connect a truck body 8 of a tractor with a hook 90 on a skip 9, and when in use, the traction mounting device 80 is mounted on the truck body 8 of the tractor, and the traction mounting device 80 and the hook 90 are mounted in a butt joint manner by the movement of the truck body of the tractor (that is, a traction pin in the traction mounting device is inserted into a pin hole on the hook), so that the tractor can traction and drive the skip to move along. The traction mounting device comprises a supporting seat 1 and a plurality of components arranged on the supporting seat 1, wherein the components comprise a mounting part 100, a traction pin shaft 2, an electric push rod 3, a limiting piece 4 and an unlocking piece 5. Wherein the mounting portion 100 is adapted for fixed connection with a tractor. The traction pin shaft 2 is provided with a mounting position and an unlocking position, and the traction pin shaft 2 is configured to be inserted into a pin hole of the hook when being positioned in the mounting position and separated from the hook when being positioned in the unlocking position. The electric push rod 3 is used for driving the traction pin shaft 2 to rise from the mounting position to the unlocking position (namely, after the traction work is completed, the traction pin shaft 2 is driven to deviate from the pin hole of the hook and rise to the unlocking position). The limiting piece 4 is used for limiting the traction pin shaft 2 to an unlocking position, the unlocking piece 5 is used for releasing the limitation so that the traction pin shaft 2 descends from the unlocking position to a mounting position under the action of gravity, and the unlocking piece 5 is configured to be pushed by a hook in the mounting process to drive the limiting piece 4 to act so as to release the limitation. When the traction operation is not required, the traction pin shaft 2 is kept at the unlocking position, and when the traction operation is required (namely, when the traction pin shaft 2 is required to be inserted into the pin hole of the hook), the limitation is released through the unlocking piece 5. Therefore, in the mounting operation, the lifting operation of the traction pin shaft 2 is only required to be performed once and then limited to the unlocking position by the limiting piece 4, so that the time of the mounting operation can be saved.

The support base 1 in this embodiment includes a base 10 and a support frame 12 fixed to the base 10, and both are fixed by screw connection of bolts in this embodiment. The support frame 12 is provided with a slideway along the vertical direction, and the traction pin shaft 2 is arranged in the slideway in a sliding way. In addition, the base 10 includes a base plate 101 and a mounting portion 100 fixed to the base plate 101, the mounting portion 100 in this embodiment is plate-shaped, a through hole through which a bolt passes is provided in the mounting portion 100, and in use, the traction mounting device is screwed and connected to the truck body 8 of the tractor by the bolt passing through the through hole in the mounting portion 100. It is easy to understand that in other embodiments, the mounting portion and the body of the tractor may be fixed by welding, clamping, or the like, and the embodiment adopts a threaded connection manner, which has the advantage of easy disassembly. In this embodiment, the electric push rod is used to drive the traction pin to rise from the mounting position to the unlocking position, and in other embodiments, other linear driving mechanisms may be used to drive the traction pin.

The linear driving mechanism can be used for driving the traction pin shaft 2 to ascend from the mounting position to the unlocking position, so that the preparation before mounting is realized; the unlocking piece 5 is pushed by the hook in the mounting operation process to push the limiting piece 4 to act so as to release the limitation of the limiting piece 4 on the traction pin shaft 2, so that the traction pin shaft 2 can descend from the unlocking position to the mounting position under the action of gravity. Thereby realizing the automatic mounting and automatic separation of the traction pin shaft 2 and the hook, saving labor cost and operation time and simultaneously avoiding potential safety hazard. In addition, as described above, in the mounting operation, the lifting operation of the traction pin shaft 2 is only required to be performed once and then limited to the unlocking position by the limiting piece 4, so that the time of the mounting operation can be saved.

As shown in fig. 3, 4 and 5, the base 10 of the present embodiment has a bottom plate 101, the support frame 12 has a support plate 124 above the bottom plate 101, a mounting chamber for the hook to enter is formed between the bottom plate 101 and the support plate 124, and the support plate 124 is located below the slideway and has a through hole for the traction pin 2 to pass through. Two opposite C-shaped baffles 120 are arranged on the support frame 12 at intervals along the vertical direction, a slideway is formed by surrounding the two C-shaped baffles 120, and the traction pin shaft 2 is arranged in the slideway in a sliding way. The traction pin shaft 2 comprises a pin shaft section 20 and a connecting seat 21 fixed on the pin shaft section 20, and a rolling bearing 210 matched with the inner wall of the C-shaped baffle 120 is arranged on the connecting seat 21. In this embodiment, rolling bearings 210 adapted to the C-shaped baffle plates 120 on the corresponding sides are respectively disposed on two opposite side surfaces of the connecting seat 21, three sets of rolling bearings 210 are disposed on each side, two sets of rolling bearings 210 are disposed on each set, it is easy to understand that the inner wall of the C-shaped baffle plate 120 includes a bottom wall and two side walls, one set of rolling bearings 210 in rolling contact with the bottom wall, and the other two sets of rolling bearings 210 in rolling contact with the side walls. The sliding of the traction pin shaft 2 is more stable by the cooperation of the C-shaped baffle 120 and the rolling bearing 210, so that the traction pin shaft 2 can be accurately inserted into the pin hole of the hook when sliding downwards under the action of gravity. Further, in order to reduce the sliding friction force applied to the traction pin 2, in this embodiment, an oilless bushing 125 is further disposed at the bottom of the slideway, and the lower portion of the pin section 20 of the traction pin 2 passes through the oilless bushing 125.

The electric putter 3 in this embodiment is fixed mounting in base 10, specifically, is fixedly provided with the U-shaped mounting bracket in the below of bottom plate 101 to corresponding being provided with on bottom plate 101 and being used for dodging electric putter 3 dodges the hole, with electric putter 3 fixed mounting on the U-shaped mounting bracket and electric putter 3's upper end can be stretched out by dodging the hole. The design can fully utilize the space and reduce the overall height of the traction mounting device. Further, in this embodiment, a connecting rod 30 facing the traction pin 2 is further disposed at the output end of the electric push rod 3, and the connecting rod 30 is configured to be capable of contacting with the traction pin 2 and pushing the traction pin 2 to rise to an unlocking position when driven by the electric push rod 3 to rise. It should be noted that, in this embodiment, the connecting rod 30 is configured to be capable of contacting with the traction pin 2 instead of fixedly connecting the two, specifically, the connecting rod 30 has a pushing portion 301, a pushing block 212 adapted to the pushing portion 301 is disposed on the connecting seat 21 of the traction pin 2, and the pushing block 212 is located directly above the pushing portion 301, so that when the connecting rod 30 is driven to rise to contact with the pushing block 212, a force can be applied to the pushing block 212, thereby driving the traction pin 2 to rise together. Therefore, when the traction pin shaft 2 is required to be separated from the hook, the electric push rod 3 drives the connecting rod 30 to ascend and apply force to the push block 212 so as to drive the traction pin shaft 2 to ascend until unlocking, and then the electric push rod 3 can immediately fall back with the connecting rod 30, so that early-stage preparation work is already done when mounting is required (the connecting rod 30 does not interfere the falling of the traction pin shaft 2), and the time of mounting operation is saved. In order to make the connecting rod 30 stable during lifting, a sliding rail 121 is provided on the supporting frame 12 in the vertical direction in this embodiment, and the connecting rod 30 has a sliding portion 300 slidably disposed on the sliding rail 121.

The structure and the working principle of the stopper 4 and the unlocking member 5 in the present embodiment are described below with reference to fig. 6, 7 and 8: the limiting member 4 in this embodiment includes a base plate 40 and a limiting plate 41, and in order to facilitate assembling the limiting member 4, the supporting frame 12 in this embodiment is provided with a supporting plate 122, and the base plate 40 is rotatably disposed on the supporting plate 122. Specifically, the bearing plate 122 is provided with a rotation shaft, and the base plate 40 is provided with a rotation shaft mounting hole 402 rotatably engaged with the rotation shaft. For ease of description, the axis of the shaft or shaft mounting hole 402 will be referred to as the longitudinal axis, and thus the base plate 40 is rotatably disposed about the longitudinal axis to the carrier plate 122. The limiting plate 41 in this embodiment is rotatably disposed on the base plate 40 around the transverse axis, and the connecting seat 21 of the traction pin shaft 2 is provided with a limiting projection 211 adapted to the limiting plate 41, and since the limiting plate 41 is rotatably connected to the base plate 40, in the ascending process of the traction pin shaft 2, the limiting projection 211 will push the limiting plate 41 to rotate the limiting plate 41, so that the limiting plate 41 will avoid, and the limiting projection 211 can continue to rise to a height higher than the limiting plate 41. In this embodiment, a torsion spring (not shown) is further disposed between the limiting plate 41 and the base plate 40, so that the limiting plate 41 has a downward rotation tendency, and after the limiting bump 211 rises to a height higher than the limiting plate 41, the limiting plate 41 will rotate downward to reset under the action of the torsion spring due to the loss of the pushing force of the limiting bump 211. The base plate 40 in this embodiment further has a locking portion 400, and the limiting plate 41 is pressed against the locking portion 400 when rotated downward to be parallel to the base plate 40, so that the locking portion 400 has a limiting effect on the limiting plate 41, and the limiting plate 41 can have a limiting effect on the limiting bump 211. Through the design, after the electric push rod 3 pushes the traction pin shaft 2 to rise to the preset highest position through the connecting rod 30, the electric push rod 3 drives the connecting rod 30 to fall back to the original position, the traction pin shaft 2 falls after losing the thrust of the connecting rod 30, at the moment, the limiting plate 41 is located below the limiting convex block 211, after the traction pin shaft 2 falls for a small distance, the limiting convex block 211 is propped against the limiting plate 41, the limiting plate 41 limits the traction pin shaft 2, and the traction pin shaft 2 is kept at the unlocking position. Or, a limit structure for limiting the upward rotation range of the limit plate can be arranged on the substrate, and the limit plate is limited to rotate to be perpendicular to the substrate through the limit structure, so that the limit plate always keeps inclined with the substrate in the process of being pushed by the limit position lug to rotate relative to the substrate. Therefore, after the limit lug rises to a height higher than the limit plate, the limit plate can also rotate downwards to reset under the action of gravity due to the loss of the thrust of the limit lug. It is easy to understand that the guiding surface is arranged on the limit bump to facilitate the proceeding of the action process.

The unlocking member 5 in the present embodiment includes a movable plate 50 slidably disposed on the base 10 and a push plate 51 fixedly mounted on the movable plate 50. A first elastic member 123 is disposed between the base plate 40 and the support frame 12 to enable the base plate 40 to have a tendency to rotate around a first set direction, and the supporting plate 122 is provided with a limiting boss 1220 for limiting the rotation degree of the base plate 40 along the first set direction, in this embodiment, the first elastic member 123 is a tension spring, which is always in a stretched state, that is, the tension spring always applies a tensile force to the base plate 40, but the base plate 40 is kept stable relative to the support frame 12 under the action of the limiting boss 1220. When the docking and mounting operation is performed, the hook stretches into the mounting cavity, and along with the forward movement of the hook relative to the tractor, the hook can form a pushing action on the movable plate 50, the movable plate 50 drives the push plate 51 to move together under the pushing of the hook, an actuating part 510 is formed on the push plate 51, and then the actuating part 510 pushes the substrate 40 to rotate along a second setting direction (the second setting direction is opposite to the first setting direction), the substrate 40 drives the limiting plate 41 to synchronously rotate when rotating, so that the limiting plate 41 is separated from the limiting lug 211, and the limitation of the limiting plate 41 on the traction pin shaft 2 is relieved. Because the second setting direction is opposite to the first setting direction, the tension spring is further stretched in the process of butt-joint mounting, when the tractor moves forwards to bring the skip car to move after the butt-joint mounting is completed, the hook moves backwards relative to the tractor, and after the pushing action of the hook is lost, the tension spring drives the base plate 40 to rotate along the first setting direction to restore to the original position by applying a tensile force to the base plate 40. It is readily understood that a person skilled in the art can easily think of a simple modification of the above-disclosed structure based on the principle and concept thereof, for example, if the tension spring in the present embodiment basically has a tendency to rotate counterclockwise, i.e., the first set direction is counterclockwise, when viewed in the top-down direction. However, in other embodiments, the first setting direction may be set to be clockwise, and only the relative positions of the tension spring, the stopper and the unlocking member need to be changed. Further, the base plate 40 in this embodiment is fixedly provided with a longitudinal axis, the longitudinal axis is rotatably provided with a bearing 401, and the actuating portion 510 presses the bearing 401 during mounting. The actuating part 510 pushes the base plate 40 to rotate by pressing the bearing 401, so that friction effect during pressing can be reduced, abrasion is reduced, and the service life of the whole traction mounting device is prolonged.

Although the movable plate 50 is reacted to the movable plate 50 to complete the reset during the reset of the substrate 40, in consideration of the service life and the reset effect of the first elastic member 123, a second elastic member is further disposed between the movable plate 50 and the supporting frame 12 in the present embodiment, so that the movable plate 50 has a tendency to slide toward the hooks, and in the present embodiment, the movable plate 50 is provided with a first mounting post 500, and the second elastic member is a spring (not shown in the figure) sleeved outside the first mounting post 500.

In order to reduce the difficulty of the mounting operation and increase the mounting success rate, in the present embodiment, a left guide plate 60 and a right guide plate 61 for guiding the hooks into the mounting chamber are rotatably disposed between the bottom plate 101 and the support plate 124, and the left guide plate 60 and the right guide plate 61 are configured with a third elastic member 63 such that they have a gathering tendency, and the third elastic member 63 is a torsion spring in the present embodiment. Through the cooperation of bottom plate 101, backup pad 124, left deflector 60 and right deflector 61, can form movable opening at the one end that the mount cavity was towards the couple, can reduce the operation degree of difficulty, promote the success rate in the in-process that the control couple stretches into to the mount cavity inside like this. Further, in this embodiment, a lower guide plate 62 for guiding the hooks into the mounting chamber is also provided on the bottom plate 101. It will be appreciated that in other embodiments, the upper guide plate may be provided instead of the lower guide plate, or both.

The bottom plate 101 in the embodiment is fixedly provided with first limit protrusions 1010 on the inner sides of the left guide plate 60 and the right guide plate 61, and the bottom plate 101 is movably provided with second limit protrusions 70 on the outer sides of the left guide plate 60 and the right guide plate 61; the second stopper protrusion 70 has an extended state and a retracted state, the second stopper protrusion 70 is higher than the upper surface of the bottom plate 101 in the extended state and limits the left and right guide plates 60 and 61, and the second stopper protrusion 70 is lower than the upper surface of the bottom plate 101 in the retracted state. Specifically, as shown in fig. 10, a carrier plate 11 is disposed below the bottom plate 101, a lifting plate 7 is disposed between the carrier plate 11 and the bottom plate 101, and a fourth elastic member 710 is disposed between the carrier plate 11 and the lifting plate 7 such that the lifting plate 7 has a tendency to move toward the bottom plate 101 to apply force to the lifting plate 7, and the second limiting protrusion 70 is fixed to the lifting plate 7. Specifically, in this embodiment, the second mounting post 71 is disposed below the lifting plate 7, and the fourth elastic member 710 is a spring sleeved outside the second mounting post 71. The bottom plate 101 is provided with a through hole for the second limiting protrusion 70 to pass through and a shaft hole 1011 for the lower end of the traction pin shaft 2 to pass through, when the traction pin shaft 2 is positioned at the mounting position, the bottom end of the traction pin shaft 2 presses the lifting plate 7 and the second limiting protrusion 70 is in a retracted state; when the traction pin shaft 2 is in the unlocking position, the lifting plate 7 is lifted up under the action of the fourth elastic piece 710, and the second limiting protrusion 70 is in an extending state.
