Technical Field

[0001] The present application relates to the technical field of transport vehicles, and in particular to an intelligent transport vehicle. Background Art

[0002] An intelligent transport vehicle refers to a transport vehicle equipped with electromagnetic, optical or visual automatic guidance devices, which can safely deliver goods to designated locations without a driver; intelligent transport vehicles can transport different objects, especially items that are inconvenient for workers to carry or dangerous items, such as the transportation of lead cans containing radioactive liquid medicine.

[0003] Regarding the above-mentioned related technologies, when transporting lead cans, they may overturn, resulting in a defect of low safety during the transportation process. Summary of the Invention

[0004] In order to solve the defect of low safety in the transportation process, the present application provides an intelligent transport vehicle.

[0005] The present application provides an intelligent transport vehicle, which adopts the following technical solutions: comprising: a transport vehicle body; a accommodating cylinder, which is a rectangular tubular structure with a closed bottom end, the accommodating cylinder is vertically inserted into the transport vehicle body and fixedly connected to the transport vehicle body, and the upper end surface of the accommodating cylinder is coplanar with the carrying surface of the transport vehicle body; a carrying plate, which is a circular plate-shaped structure, is located in the accommodating cylinder and slides along the length direction of the accommodating cylinder, and is used to carry items to be transported; the upper surface of the carrying plate is coplanar with the upper end surface of the accommodating cylinder; the carrying plate is provided with a clearance groove along its radial direction, and there are two clearance grooves, and the two clearance grooves are opposite to each other; a clamping member, which is connected to the accommodating cylinder, The clamping member includes a clamping rod, a clamping plate and an adjusting shaft; there are two clamping rods, and the two clamping rods are respectively located in the two give way grooves; the adjusting shaft passes through the clamping rod and is rotatably connected to the clamping rod and is fixedly connected to the accommodating cylinder, and the distance between the two clamping rods gradually increases from the end close to the adjusting shaft to the end away from the adjusting shaft; the clamping plate is an arc-shaped plate structure, the clamping plate is connected to the top of the clamping rod and the concave surfaces of the two clamping plates are facing each other; the transmission member is connected to the carrying plate, and is used to drive the two clamping plates to move toward the side close to each other and clamp the items to be transported.

[0006] By adopting the above technical solution, the items to be transported are placed on the upper surface of the carrying plate during use. At this time, the carrying plate moves downward under the action of the gravity of the transported items. Under the action of the transmission part, the clamping rod drives the two clamping plates to move toward each other until the two clamping plates clamp the items to be transported. At this time, the carrying plate no longer slides down, which achieves the effect of locking and fixing the items by utilizing the gravity of the transported items. At the same time, the gravity of the items to be transported is proportional to the force of the clamping parts clamping the items, thereby achieving the effect of improving the safety of the item transportation process.

[0007] Preferably, the transmission member includes: a connecting rod, which is vertically fixedly connected to the center position of the lower surface of the supporting plate; a support plate, which is vertically fixedly connected to the remaining end of the connecting rod and is parallel to the supporting plate; two transmission rods are provided, and the bottom ends of the transmission rods are hinged to the support plate; the distance between the two transmission rods gradually increases from the bottom end to the top end; the two transmission rods are located on the side of the two clamping rods facing away from each other; a transmission block, which is fixedly connected to the top end of the transmission rod and abuts against the two clamping rods respectively; a limiting ring, which is sleeved on the outside of the two transmission rods and located at the bottom ends of the two transmission rods; the limiting ring is used to adjust the distance between the top ends of the two transmission rods to reduce; a support spring, which is fixedly connected to the lower surface of the support plate.

[0008] By adopting the above technical solution, the carrying plate moves along the length direction of the accommodating cylinder under the action of the gravity of the items to be transported, and under the action of the connecting rod, it drives the support plate to move downward, and then drives the transmission rod hinged on the upper surface of the support plate to move downward. Under the action of the limit ring, the top ends of the two transmission rods move toward the side close to each other, and at the same time, under the action of the transmission block, the two clamping rods are pushed to move toward the side close to each other, thereby clamping the items; the heavier the items to be transported, the higher the clamping force, thereby realizing automatic clamping of the items to be transported, and achieving the effect of facilitating use by the staff.

[0009] Preferably, the accommodating cylinder is fixedly connected to a guide rod, which passes through the supporting plate and is slidably connected to the supporting plate.

[0010] By adopting the above technical solution, the guide rod limits the support plate from moving up and down along the accommodating tube. At the same time, the support plate is in a relatively fixed state with the supporting plate under the action of the connecting rod, thereby limiting the sliding of the supporting plate along the length direction of the accommodating tube, thereby improving the stability of use.

[0011] Preferably, a return spring is provided between the top ends of the side walls of the two clamping rods facing away from each other and the inner wall of the accommodating tube.

[0012] By adopting the above technical solution, when the upper surface of the carrying plate is coplanar with the upper surface of the carrier body, the top ends of the two clamping rods are tilted to the side away from each other, making it easier for staff to place items between the two clamping plates, thereby achieving the effect of facilitating use by staff.

[0013] Preferably, a rocker arm is provided between the clamping rod and the clamping plate, one end of the rocker arm is fixedly connected to the clamping rod, and the remaining end is hinged to the clamping plate.

[0014] By adopting the above technical solution, the setting of the swing rod can facilitate the clamping plate to adjust the clamping objects according to the different shapes of the objects to be transported.

[0015] Preferably, the side wall of the transmission block close to the clamping rod is an arc surface.

[0016] By adopting the above technical solution, the contact surface between the transmission block and the clamping rod is an arc-shaped surface, which reduces the friction between the transmission block and the clamping rod while pushing the clamping rod, thereby reducing wear.

[0017] Preferably, a locking groove is provided along the radial direction of the support plate, and there are two locking grooves, which are opposite to each other; a locking piece is provided in the accommodating tube, and the locking piece includes a locking ring, a locking rod and a locking spring; the locking spring is located in the locking groove; the locking rod is inserted into the locking groove and fixedly connected to the locking spring; the side walls of the two locking rods facing away from each other gradually incline from the top to the bottom toward the side close to the locking spring; a plurality of locking rings are provided and distributed along the length direction of the accommodating tube, and the locking rod is inserted between two adjacent locking rings; the locking piece is connected to an unlocking piece, and the unlocking piece is used to accommodate the locking rod into the locking groove.

[0018] By adopting the above technical solution, when the clamping plate clamps the item to be transported, under the action of the locking spring, the locking spring pushes the locking rod to be inserted between the two adjacent locking rings, thereby achieving the relative position between the fixed support plate and the accommodating cylinder, thereby improving the stability of the item clamping.

[0019] Preferably, the connecting rod is a hollow tubular structure and passes through the support plate; the unlocking part includes an unlocking rod and an unlocking steel cable; the unlocking steel cable is fixedly connected to the side walls of the two locking rods close to each other and is slidably connected to the support plate; the unlocking rod is inserted into the connecting rod and abuts the unlocking steel cable.

[0020] By adopting the above technical solution, after the item to be transported is taken out from between the two clamping plates, the unlocking rod is used to abut the unlocking steel cable and push the unlocking rod downward. At this time, the unlocking steel cable drives the two locking rods to retract into the locking groove, thereby achieving the effect of being convenient for staff to use.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Place the item to be transported on the upper surface of the carrier plate. The carrier plate then moves downward under the weight of the item to be transported. Under the action of the transmission member, the clamping rod drives the two clamping plates to move closer to each other until the two clamping plates clamp the item to be transported. At this time, the carrier plate no longer slides down, thus achieving the effect of locking and fixing the goods by utilizing the weight of the transported goods. At the same time, the weight of the item to be transported is proportional to the force of the clamping member clamping the item, thereby achieving the effect of improving the safety of the item transportation process.

[0023] 2. The load plate moves along the length of the accommodating cylinder under the action of the gravity of the object to be transported. Under the action of the connecting rod, the supporting plate is driven downward, which in turn drives the transmission rod hinged to the upper surface of the supporting plate to move downward. Under the action of the limit ring, the top ends of the two transmission rods move toward each other. At the same time, the transmission block pushes the two clamping rods toward each other to clamp the object. The heavier the object to be transported, the higher the clamping force. This realizes automatic clamping of the object to be transported, making it convenient for workers to use.

[0024] 3. After the clamping plate clamps the item to be transported, the locking spring pushes the locking rod to be inserted between the two adjacent locking rings under the action of the locking spring, thereby fixing the relative position between the support plate and the accommodating cylinder, thereby improving the clamping stability of the item.

[0031] refer to Figure 1 and Figure 2The clamping member 4 is connected to the accommodating tube 2 and is used to fix and clamp the items to be transported. Specifically, the clamping member 4 includes a clamping rod 41, a clamping plate 42, and an adjustment shaft 43. Two clamping rods 41 are provided, and the two clamping rods 41 are respectively located in the two clearance grooves 31. The adjustment shaft 43 passes through the clamping rod 41 and is rotatably connected to the clamping rod 41. The adjustment shaft 43 is fixedly connected to the accommodating tube 2. The distance between the two clamping rods 41 gradually increases from the end close to the adjustment shaft 43 to the end away from the adjustment shaft 43. The clamping plate 42 is an arc-shaped plate structure. The clamping plate 42 is connected to the top of the clamping rod 41, and the concave surfaces of the two clamping plates 42 are facing each other. Specifically, a rocker arm 8 is provided between the clamping rod 41 and the clamping plate 42. One end of the rocker arm 8 is fixedly connected to the clamping rod 41, and the remaining end is hinged to the clamping plate 42. A return spring 7 is provided between the top ends of the side walls of the two clamping rods 41 which are away from each other and the inner wall of the accommodating tube 2 .

[0032] refer to Figure 1 and Figure 2 The transmission member 5 is connected to the carrier plate 3 and is used to drive the two clamping plates 42 toward each other and clamp the items to be transported. Specifically, the transmission member 5 includes a connecting rod 51, a support plate 52, a transmission rod 53, a transmission block 54, a retaining ring 55, and a support spring 56. The connecting rod 51 is vertically fixed to the center of the lower surface of the carrier plate 3. The support plate 52 is vertically fixed to the remaining end of the connecting rod 51 and is parallel to the carrier plate 3. The upper surface of the support plate 52 is fixedly connected to the connecting rod 51. In this embodiment, the connecting rod 51 is a hollow tubular structure, and the cavity of the connecting rod 51 passes through the carrier plate 3 and the support plate 52.

[0033] refer to Figure 1 and Figure 2 There are two transmission rods 53, and the bottom ends of the two transmission rods 53 are hinged to the support plate 52. The distance between the two transmission rods 53 gradually increases from the bottom end to the top end; and the two transmission rods 53 are located on the side of the two clamping rods 41 that are away from each other; the transmission block 54 is fixedly connected to the top end of the transmission rod 53 and respectively abuts against the two clamping rods 41. The side wall of the transmission block 54 close to the clamping rod 41 is an arc surface. The limiting ring 55 is sleeved on the outside of the two transmission rods 53 and is located at the bottom end of the two transmission rods 53; the limiting ring 55 is used to adjust the distance between the top ends of the two transmission rods 53 to decrease. The support spring 56 is fixedly connected to the lower surface of the support plate 52. The bottom end of the accommodating cylinder 2 is fixedly connected to a guide rod 6, which passes through the support plate 52 and is slidably connected to the support plate 52.

[0034] During use, the load plate 3 moves along the length of the accommodating tube 2 under the action of the gravity of the items to be transported. At this time, the load plate 3 drives the connecting rod 51 downward, which in turn drives the support plate 52 downward. This in turn drives the transmission rod 53 hinged to the upper surface of the support plate 52 downward. Because the position and diameter of the limit ring 55 remain unchanged, the limit ring 55 causes the top ends of the two transmission rods 53 to move toward each other. Simultaneously, the transmission block 54 pushes the two clamping rods 41 toward each other, thereby clamping the items. The heavier the items to be transported, the higher the clamping force. This achieves automatic clamping of the items to be transported, making it easier for workers to use. After the items placed on the upper surface of the load plate 3 are removed, the spring drives the support plate 52 upward, returning the load plate 3 to its original position. The clamping rods 41 are then reset under the action of the reset spring 7.

[0035] refer to Figure 1 and Figure 2 The support plate 52 is provided with a locking groove 521 along its radial direction, and there are two locking grooves 521, which are opposite to each other; a locking piece 9 is provided in the accommodating tube 2, and the locking piece 9 includes a locking ring 91, a locking rod 92 and a locking spring 93; the locking spring 93 is located in the locking groove 521; the locking rod 92 is inserted into the locking groove 521 and is fixedly connected to the locking spring 93; the side walls of the two locking rods 92 that are away from each other gradually tilt from the top end to the bottom end toward the side close to the locking spring 93.

[0036] refer to Figure 1 and Figure 2 , multiple locking rings 91 are provided, and the locking rings 91 are evenly spaced along the length direction of the accommodating tube 2, and the locking rod 92 is inserted between two adjacent locking rings 91. The locking member 9 is connected to the unlocking member 10. The unlocking member 10 is used to accommodate the locking rod 92 in the locking groove 521. The connecting rod 51 is a hollow tubular structure, and the connecting rod 51 passes through the supporting plate 52; the unlocking member 10 includes an unlocking rod 101 and an unlocking cable 102; the unlocking cable 102 is fixedly connected to the side walls of the two locking rods 92 that are close to each other and is slidably connected to the supporting plate 52; the unlocking rod 101 is inserted into the connecting rod 51 and abuts the unlocking cable 102.

[0037] During use, after the clamping plate 42 clamps the item to be transported, under the action of the locking spring 93, the locking spring 93 pushes the locking rod 92 to be inserted between the two adjacent locking rings 91, thereby achieving the relative position between the fixed support plate 52 and the accommodating cylinder 2, thereby improving the stability of the item clamping; after the item to be transported is taken out from between the two clamping plates 42, the unlocking rod 101 is used to abut the unlocking steel cable 102 to push the unlocking rod 101 downward, at this time the unlocking steel cable 102 drives the two locking rods 92 to retract into the locking groove 521, thereby achieving the effect of being convenient for staff to use.

[0038] The operating principle of the intelligent transport vehicle according to the embodiment of the present application is as follows: the items to be transported are placed on the upper surface of the carrier plate 3. Under the action of the gravity of the items to be transported, the carrier plate 3 drives the connecting rod 51 and the supporting plate 52 downward. Under the limit of the limiting ring 55, the top ends of the two transmission rods 53 tilt toward each other. This causes the transmission block 54 to push the clamping rod 41 toward each other and tilt, thereby clamping the items to be transported, thereby improving the safety of the transportation process. At the same time, the locking rod 92 is inserted between two adjacent locking rings 91 to fix the relative position between the supporting plate 52 and the accommodating cylinder 2, further improving the safety of the transportation process.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
