Description

Technical Field

[0001] The invention relates to the technical field of transport vehicles, in particular to an assembly vehicle transport device which is easy to operate. Background Art

[0002] An assembly vehicle refers to a vehicle equipped with special tools and equipment and provided to maintenance personnel in a movable form. In the prior art, an assembly vehicle frame disclosed in Chinese patent application No. 202023079706.1 provides a specific structure and working principle of an assembly vehicle.

[0003] Existing assembly vehicles are usually pushed manually. In order to save manpower, some assembly vehicles are combined with power systems, such as the existing AGV cart that can be used as a transport vehicle (AGV is an unmanned transport vehicle equipped with automatic guidance devices such as electromagnetic or optical devices. AGV can travel along a specified guide path, has safety protection and various transfer functions, and is an important equipment in the field of modern industrial automation and intelligence). A support frame is directly set on the AGV, so that the AGV can be used as a self-driven assembly vehicle after modification, such as the fuel cell system assembly vehicle disclosed in Chinese patent application No. 202223553703.6.

[0004] However, the assembly vehicle is essentially a mobile tool, and most of the processing of the parts that move on the assembly vehicle is not carried out on the assembly vehicle, but the parts need to be removed from the assembly vehicle for processing. In the process of removing the parts from the assembly vehicle, the assembly vehicle can only remain motionless, and the power system of the assembly vehicle cannot work during this period; in addition, since the demand for different parts in different production links is different, directly equipping the assembly vehicle with a power structure will result in different types of assembly vehicles required in different links, and the power system itself is high-cost. Equipping enough assembly vehicles will increase the production cost of the workshop (i.e., the purchase cost of the assembly vehicle and the maintenance cost of the assembly vehicle).

[0005] In order to allow the transport vehicle to drive the assembly vehicle to move, a hook structure that cooperates with the assembly vehicle needs to be set on the transport. In the prior art, for example, Chinese patent application No. 201720578608.1 discloses an AGV traction hook identification device and a traction AGV, which has a hook that allows a pallet truck (equivalent to the above-mentioned assembly vehicle) to be hung on the AGV through the hook, thereby realizing the movement of the pallet truck driven by the transport vehicle.

[0006] However, the above-mentioned reference document is very troublesome when connecting and separating the AGV and the assembly vehicle. First, the bottom plate 42 needs to be aligned with the hole on the traction hook 5, and then the traction pin 44 needs to be inserted into the aligned hole. The operation of aligning the holes and passing the pin through the two aligned holes at the same time is cumbersome. Therefore, the connection process of connecting the transport vehicle and the assembly vehicle is cumbersome. Summary of the invention

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should be noted that the terms used in the present invention are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0026] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0027] Embodiment 1:

[0028] The existing transport vehicle and assembly vehicle are inconvenient to operate when connecting, mainly because the steps of aligning the holes on the transport vehicle with the holes on the assembly vehicle and inserting the pins into the two holes for fixing are cumbersome. In order to simplify these steps, the transport vehicle and the assembly vehicle are convenient to assemble, thereby facilitating the user to connect the transport vehicle and the assembly vehicle and improving work efficiency, the assembly vehicle transport device with easy operation provided in Embodiment 1 of the present invention is as follows: Figures 1 to 7 As shown, it includes a transport vehicle body 1 and a hook assembly body 2; the hook assembly body 2 includes a fixed seat 21 and a transport pin assembly 22; the fixed seat 21 is fixed on the transport vehicle body 1; the fixed seat 21 includes an automatic clamp 211; the transport pin assembly 22 includes a transport pin shaft 221; the automatic clamp 211 includes an open state and a closed state; after the transport pin shaft 221 moves into the automatic clamp 211 in the open state, the automatic clamp 211 can automatically switch to the closed state to limit the transport pin shaft 221.

[0029] When the easy-to-operate assembly vehicle transportation device provided in Example 1 of the present invention is in use, it is necessary to fix the transport pin assembly 22 on each assembly vehicle in advance, so that the user can push the assembly vehicle to push the transport pin shaft assembly 22 to cooperate with the fixed seat 21; when actually controlling the connection between the assembly vehicle and the transport vehicle, the staff pushes the assembly vehicle to move the transport pin shaft 221 toward the open automatic clamp 211 (the automatic clamp 211 is a prior art, such as the automatic clamp 211 disclosed in Chinese patent application No. 202122954906.5, which is not described in detail here), until the transport pin shaft 221 is completely moved into the automatic clamp 211, the automatic clamp 211 automatically closes, thereby clamping the transport pin shaft 211 to a limit position; in the prior art, it is necessary to align the two holes, and then insert the pin shaft to align the two holes (the holes on the assembly vehicle and the transport vehicle) The hole on the transport trolley) is limited, thereby realizing that the assembly trolley and the pin shaft can be rotatably fixed, and the transport trolley and the pin shaft can be rotatably fixed; the structure provided in this embodiment can more simply realize the rotatable connection between the assembly trolley and the transport trolley (after the automatic clamp 211 limits the transport pin shaft 221, the limiting pin shaft 221 can rotate along its own pin shaft axis), which is more simply reflected in that the automatic clamp 211 in the open state has a larger accommodating space than the hole of a fixed pin shaft, and the automatic clamp 211 can drive the limiting pin shaft 221 to move during the process of switching to the closed state, thereby moving the fiber pin shaft 221 to the specified position. Therefore, compared with the prior art, the equipment provided in this embodiment can more simply realize the rotatable connection between the assembly trolley and the transport trolley, so the connection steps between the transport trolley and the assembly trolley are convenient, saving the connection time of the staff and improving the connection efficiency of the staff.

[0030] The easy-to-operate assembly vehicle transport device provided by the embodiment of the present invention solves the problem of complicated steps in connecting the transport vehicle and the assembly vehicle in the prior art, and can facilitate the connection between the transport vehicle and the assembly vehicle.

[0031] In order to realize the switching of the automatic clamping jaw 211 between the open state and the closed state, as a preferred solution, in this embodiment, the fixing seat 21 also includes a bottom plate 212; the automatic clamping jaw 211 includes a left clamping jaw 2111, a right clamping jaw 2112, a spring 2113 and a positioning assembly 3; the left clamping jaw 2111 can be rotatably fixed on the bottom plate 212; the right clamping jaw 2112 can be rotatably fixed on the bottom plate 212; the left clamping jaw 2111 and the right clamping jaw 2112 are connected by a spring 2113; in the process of the left clamping jaw 2111 rotating relative to the bottom plate 212 and the right clamping jaw 2112 rotating relative to the bottom plate, the automatic clamping jaw 211 switches between the open state and the closed state; the left clamping jaw 2111 and the right clamping jaw 2111 are connected by a spring 2113. When only affected by the tension of the spring 2113, the automatic clamp 211 is in an open state; abutment surfaces are provided on the left clamp 2111 and the right clamp 2112; when the transport pin 221 moves toward the automatic clamp 211 in the open state, the transport pin 221 will contact the abutment surfaces on the left clamp 2111 and the right clamp 2112; when the transport pin 221 contacts the abutment surfaces, the transport pin 221 can push the left clamp 2111 and the right clamp 2112 to rotate relative to the bottom plate, and make the spring 2113 stretched and tightened until the automatic clamp 211 is rotated to the closed state; the positioning assembly 3 is fixed on the bottom plate 212; the positioning assembly 3 can lock and release the closed state of the automatic clamp 211. When the assembly vehicle and the transport vehicle need to be connected, after the transport pin 221 moves to the automatic clamp 211 in the open state, the transport pin 221 will contact the abutment surface and push the left clamp 2111 and the right clamp 2112 to rotate relative to the bottom plate 212, thereby tightening the left clamp 2111 and the right clamp 2112. At the same time, the spring 2113 will be stretched, and the left clamp 2111 and the right clamp 2112 will be locked by controlling the positioning component 3 (i.e., controlling the left clamp 2111 and the right clamp 2112 relative to the bottom plate). 212 is fixed and cannot rotate) to achieve the limitation of the automatic clamp 211 on the transport pin 221; when it is necessary to separate the assembly vehicle and the transport vehicle, the locking state of the left clamp 2111 and the right clamp 2112 is released by controlling the positioning component 3, and the left clamp 2111 and the right clamp 2112 are both transported by the spring and rotated relative to the bottom plate 212, so that the left clamp 2111 and the right clamp 2112 are restored to the open state of the automatic clamp 211, and the transport pin 221 can be separated from the automatic clamp 211 in the open state.

[0032] In order to specifically realize the functions of locking and releasing the left clamping jaw 2111 and the right clamping jaw 2112 of the above-mentioned positioning assembly 3, as a preferred solution, in this embodiment, the positioning assembly 3 includes a pedal 31, a fulcrum block 32 and two positioning pins 33; the fixing seat 21 also includes a positioning plate 213; the left clamping jaw 2111 and the right clamping jaw 2113 are respectively provided with a first positioning hole 2114 extending in a vertical direction; the pedal 31 can be rotatably fixed on the fulcrum block 32; the positioning pin 33 is fixed to the fulcrum block 32 of the pedal 31. The same side of the point block 32; during the rotation of the pedal 31 relative to the fulcrum block 32, the positioning pin 33 can move in the vertical direction; the positioning plate 213 is fixed on the base plate 212; two second positioning holes are provided on the positioning plate 213; when the automatic clamp 211 is in a closed state, the positioning pin 33 can pass through the first positioning hole 2114 and the second positioning hole at the same time during the vertical movement; the positioning pin 33 can pass through the first positioning hole 2114 and the second positioning hole from the vertical top.The connection structure between the assembly vehicle and the transport vehicle body 1, that is, the transport pin assembly 22 and the fixed seat 21 are usually arranged at the bottom. This is to lower the center of gravity so that the transport vehicle body 1 can stably transport the assembly vehicle (such as an AGV traction hook identification device and traction AGV disclosed in Chinese patent application No. 201720578608.1, which sets the connection structure at the bottom. In this embodiment, the fixed seat 21 is also arranged at the bottom of the transport vehicle body 1. The transport pin assembly 22 on the assembly vehicle is connected to the fixed seat 21 and is arranged at the same height. Unlike the prior art that can only play a traction effect, the present embodiment The transport vehicle body 1 itself also has the function of transporting items. When the staff needs to assemble the items on the assembly vehicle, they can assemble them through the general tools carried on the transport vehicle body 1). Therefore, a pedal 31 is provided in this embodiment to facilitate the staff to control the positioning assembly 3 by stepping on it. The staff steps on the pedal 31 to rotate the pedal 31 relative to the fulcrum block 32, thereby realizing the vertical movement of the positioning pin 33. During the vertical movement of the positioning pin 33, the first positioning hole 2114 and the second positioning hole can be inserted and passed through. When the positioning pin 33 passes through the first When the positioning hole 2114 and the second positioning hole are aligned, the position of the first positioning hole 2114 is restricted, so that the left clamp 2111 and the right clamp 2112 cannot rotate relative to the bottom plate 212 (the rotation axis of the left clamp 2111, the right clamp 2112 and the bottom plate is vertical, the first positioning hole 2114 is opened on the left clamp 2111 and the right clamp 2112, and when the pin shaft 33 fixes the position of the first positioning hole 2114, the left clamp 2111 and the right clamp 2112 will be restricted from rotating), so that the automatic clamp 211 is stable in the closed state. When the assembly vehicle and the transport vehicle body 1 need to be separated, The staff can step on the pedal 31, and the pedal 31 rotates relative to the fulcrum block 32, and one end of the pedal 31 fixed with the positioning pin 33 is tilted, so that the positioning pin 33 is lifted vertically upward, so that the positioning pin 33 passes through the first positioning hole 2114, and there is no positioning pin 33 blocking the first positioning hole 2114, so that the left clamping jaw 2111 and the right clamping jaw 2112 are no longer restricted from rotating by the positioning pin 33. After the transport pin 221 is taken out, the left clamping jaw 2111 and the right clamping jaw 2112 rotate due to the stretching of the spring 2113, so that the bullet clamping jaw 211 is switched to an open state.

[0033] In order to realize that the positioning pin 33 remains vertical after the pedal 31 rotates relative to the fulcrum block 32, as a preferred solution, in this embodiment, the positioning plate 213 is arranged above the automatic clamp 211; a guide block 214 is fixed on the positioning plate 213; two guide holes 2141 are vertically penetrated on the guide block 214; two positioning pins 33 can slide through the guide holes 2141 to be fixed; the positioning pins 33 are always in the guide holes 2141 during the vertical movement; the upper end of the positioning pin 33 is rotatably fixed to the pedal 31. The positioning pin 33 is always in the guide hole 2141 of the guide block 214. Since the guide hole 2141 is arranged in the vertical direction, the positioning pin in the guide hole 2141 always remains vertical, and the positioning pin 33 is rotatably connected to the pedal 31. Therefore, when the positioning pin 33 moves in the vertical direction, the positioning pin 33 automatically rotates between the pedal 31.

[0034] In order to specifically realize the rotatable fixation of the pedal 31 relative to the fulcrum block 32, and the vertical movement of the positioning pin shaft 33 relative to the guide hole of the guide block 214, as a preferred solution, in this embodiment, the fulcrum block 32 includes a fixed block 321 and a hinge 322; the fixed block 321 is fixed on the positioning plate 213; the fixed block 321 and the pedal 31 are rotatably fixed by a hinge 322 with a horizontal axis. The hinge 322 is a prior art, and the hinge 322 has an axis. The structure on the two plates fixed on the hinge 322 can rotate relative to the axis of the hinge. The pedal 31 and the fixed block 321 are respectively fixed on the hinge 322 and rotated through the hinge, thereby realizing the rotation of the pedal 31 and the fixed block 321. The fixed block 321 is fixed on the positioning plate 213, and the guide block 214 is fixed on the positioning plate 213. Therefore, when the pedal 31 rotates, it will rotate relative to the positioning plate 213, and the guide block 214 will not move relative to the positioning plate 213. The positioning pin shaft 33 rotatably fixed at the end of the pedal 31 can move relative to the positioning plate 213, that is, the positioning pin shaft 33 can move vertically relative to the guide hole of the guide block 214.

[0035] To facilitate the fixation of the transport pin shaft assembly 22 and the assembly vehicle, in the present embodiment, the transport pin assembly 22 also includes an upper rotating plate 222, a lower rotating plate 223 and an assembly vehicle fixing plate 224; the upper rotating plate 222 and the lower rotating plate 223 can be rotatably fixed on the two ends of the transport pin shaft 221 respectively; the upper rotating plate 222 and the lower rotating plate 223 are both fixedly connected to the assembly vehicle fixing plate 224; a distance is left between the transport pin shaft 221 and the assembly vehicle fixing plate 224 for the claws of the left clamp 2111 and the right clamp 2112 to pass through. The assembly vehicle fixing plate 224 is fixed to the assembly vehicle so that the height of the transport pin 221 is consistent with the height of the automatic clamp. The upper rotating plate 222 and the lower rotating plate 223 are used to maintain a rotatable connection with the transport pin 221, so that the automatic clamp 211 can directly fix the transport pin 221 instead of simply restricting the transport pin 221. The connection structure between the automatic clamp 211 and the transport pin 221 is simple. A distance is left between the transport pin 221 and the assembly vehicle fixing plate 224 for the claws of the left clamp 2111 and the right clamp 2112 to pass through, in order to facilitate the automatic clamp 211 to clamp the transport pin 221.
